Surveillance of microbial contamination of mobile phones, reported behaviour and hand hygiene practices of healthcare personnel related to mobile phone use: A prospective observational study
Sunil Kumar Poonia, Poonam Joshi, Rakesh Lodha, Arti Kapil, M Srinivas
January-April 2017, 5(1):40-44
Objectives: To compare the microbial flora on the mobile phones of Health care personnel (HCP) and general public (GP) and to study the reported behaviour and observed hand hygiene practices of the HCP related to mobile phone use in paediatric medical and surgical Intensive Care Units (ICUs). Methodology: Front surface of the mobile phones of enrolled HCP and GP was sampled for culture using sterile swabs. Behaviour of the HCP was assessed using a self-report structured behaviour assessment tool. A total of 360 observations on the hand hygiene practices of the HCP related to mobile phone use in ICUs were carried out over 8 weeks using an observation checklist. Results: Of the 47 HCPs enrolled in the study, 78.7% were nurses and 21.3% were doctors. Majority of the HCPs had smartphones (85%;). Nearly 77% of mobile phones of HCP and GP were contaminated with various pathogenic, commensal and environmental bacteria. Most of HCPs were using mobile phones 1–3 times during working hours for communication, E-mailing and searching information. Two-thirds of the HCP (66) were not cleaning their phones; 38 seldom practiced hand hygiene before using the mobile phones, while better hand hygiene practices were reported after using the mobile phones (60%). More than 50% of the observed hand hygiene practices related to mobile phone usage were inappropriate or wrong. Conclusion: Mobile phones of the HCP and GP were equally contaminated; more pathogenic microorganisms were seen on the mobile surfaces of HCP. Reported behaviour and hand hygiene practices of HCP related to mobile phone use in the ICUs were inappropriate or wrong.

Air sampling procedures to evaluate microbial contamination: A comparison between active and passive methods at high-risk areas in a Tertiary Care Hospital of Delhi
Rumpa Saha, Shrreya Agarawal, Amir Maroof Khan
January-April 2017, 5(1):18-23
Context: The microbial quality of air in the operation theatres (OTs) is a parameter which appreciably controls the healthcare-associated infections. However, there is currently no international consensus on the most suitable method to be used for air sampling or any set policy on how to achieve the total viable count (TVC) values although the optimum goals have been set. Aims: This study aims to evaluate the microbial air quality in different OTs of our tertiary care hospital at rest and inoperational by comparing active and passive air sampling. Settings and Design: The Department of Microbiology and all the OT rooms of UCMS and GTB Hospital, Delhi. There are 18 OT rooms. This was a cross-sectional, comparative study. Subjects and Methods: Five at rest samples (before the start of operation) and five inoperational samples (during operation) were collected from each of the 18 OTs by both active (using air sampler) and passive (gravity settle plate technique as per the 1/1/1 scheme) methods using five percent sheep blood agar in 9 cm petri plates. The number of personnel present inoperational was recorded, and the number of colony forming units on the petri dish was counted after incubation and compared. Statistical Analysis Used: As the data followed a non-normal distribution, non-parametric tests were applied. Wilcoxon signed rank test, Spearman's correlation coefficient, Simple linear regression and Independent sample t-test. Results: The total bioburden in the OTs exceeded the maximum acceptable limit value during both moments of sampling. There was a significant positive correlation in the TVC values obtained by active and passive sampling methods in the two moments. Conclusions: The present study demonstrates a comparability of results obtained by the two different sampling techniques at two sampling moments. However, authentication of this result necessitates additional studies. In the interim, it is promising to conclude that both methods can be used for universal scrutinising of air biocontamination.

A review of prevention of surgical site infections in Indian hospitals based on global guidelines for the prevention of surgical site infection, 2016
A Arora, P Bharadwaj, H Chaturvedi, P Chowbey, S Gupta, D Leaper, GK Mani, SK S Marya, R Premnath, K Quadros, A Srivastava, A Tendolkar
January-April 2018, 6(1):1-12
While the global estimates of surgical site infection (SSI) have varied from 0.5% to 15%, studies in India have consistently shown higher rates ranging from 23% to 38%. The incidence of SSI may be influenced by factors such as pre-operative care, the theatre environment, post-operative care and the type of surgery. Many other factors influence surgical wound healing and determine the potential for, and the incidence of, infection. Therefore, the prevention of these infections is complex and requires the integration of a range of preventive measures before, during and after surgery. No standardised guidelines backed by evidence are currently established in India for the prevention of SSI. Hence, there is a need for an adaptable, executable National Guideline for low- and middle-income countries which includes India. An effort to draw out most doable and must doable action points to prevent SSI was undertaken by the panelists involved in this paper on the basis of recent global guidelines for the prevention of SSI.

Namita Jaggi, Pushpa Nirwan, Meenakshi Chakraborty
January-April 2018, 6(1):13-18
Introduction: The surgical antibiotic prophylaxis guidelines are developed to provide surgeons with a standardised approach to the rational, safe and effective use of antimicrobial agents for the prevention of surgical-site infections based on international, national and local recommendations. However, despite the availability of these guidelines, the adherence to the set protocols is a challenge. This study was carried out to evaluate the adherence to presurgical antibiotic prophylaxis in a tertiary care hospital. Materials and Methods: The antibiotic audit was prospectively carried out for 29 months January 2014—May 2016 for randomly selected clean and clean-contaminated surgeries. Measurable parameters for each selected case were choice of antibiotic, timing of administration and duration. The results were statistically analysed (Minitab 17.0 software). Results: A total of 1549 surgeries were audited. Out of this, 1501 (96.9%) surgeries fulfilled the inclusion criteria and 76.8% were clean. Mean age of the patients was 42.9 ± 18 years with the majority being females 52.5%. The most commonly used antibiotics were amikacin 32.5%, cefuroxime 29.5% and cefazolin 22.9%. The three parameters tested for adherence showed individual compliance of 87.3% for appropriate selection of antibiotic, 85.3% for appropriate administration and 34.9% for appropriate duration of antibiotic, respectively. Overall adherence to presurgical antibiotic prophylaxis guidelines by the surgeons showed significant results (69.2%, P < 0.05). Conclusion: The present study highlights the adherence and challenges faced in transforming hospital-specific guidelines into practice. The adherence to SAP protocols by surgeons was found comparable with that of the developed countries. This is due to their involvement in the formulation of antibiotic guidelines.

Catheter-associated urinary tract infection in a Tertiary Care Hospital
Areena Hoda Siddiqui, Vipul Kumar Srivastava, PP Aneeshamol, Carolyn Prakash
January-April 2017, 5(1):7-11
Background: Catheter-associated urinary tract infection (CAUTI) is due to inadvertent use of urinary catheter. This study was done to determine the confirmed CAUTI cases, infection rate, prevalence of organisms, and their sensitivity profile. Materials and Methods: A total of 1874 Foleys catheter cases were followed for 3 months. Cases were confirmed as per the Centers for Disease Control and Prevention guideline. Results: A total of 21 (6.93') CAUTI cases were confirmed from 303 culture positive samples. The most common isolate was Escherichia coli (28.57'). Isolates were found resistant to fluoroquinolones and decreased sensitivity was found to other urinary drugs with the exception being colistin which was 100' sensitive. Average infection rate was 1.78/1000 catheter days. Average of catheter days was 11825. Conclusion: To reduce morbidity and length of hospital stay and costs to the patient, unnecessary catheter insertion should be avoided. If Foley catheter insertion is needed, aseptic precaution during catheter insertion must be practiced and removal of Foleys must be done as soon as possible. Continuous education and training of the health-care workers and surveillance by infection control team play an important role in improving the practice and reducing infection.

Efficacy studies on peracetic acid against pathogenic microorganisms
Gunjan Katara, Nanda Hemvani, Sheetal Chitnis, Vikrant Chitnis, Dhananjay Sadashiv Chitnis
January-December 2016, 4(1):17-21
Background: The peracetic acid (PAA) has antimicrobial activity against bacteria and fungi including spores and is envirosafe. Despite its widespread use in food industry and effluent treatment, it is not widely used in hospitals. The present work was aimed to find out its efficacy against hospital pathogens, bacterial and fungal spores and mycobacteria. Methods: Multidrug-resistant, wild hospital isolates of Gram-positive, Gram-negative bacteria, tough organisms such as Mycobacterium fortuitum, Mycobacterium tuberculosis and Candida albicans and spores of Bacillus subtilis, Clostridium perfringens and Aspergillus niger were checked by modified Kelsey-Sykes suspension test. For vegetative bacteria, exposure time was 1 min. For bacterial and fungal spores, Candida and Mycobacteria, exposure time varied from 10 to 30 min. Results: More than 5-log reduction was seen for vegetative bacteria just after 1 min exposure to PAA. Ten minute exposure to PAA could inactivate 99.5% bacterial and fungal spores. Mycobacteria were inactivated within 10 min of exposure to PAA. PAA rapidly inactivates pathogenic bacteria within 1 min and inactivates mycobacteria and fungi within 10 min and sterilises spores within 30 min and remains active in the presence of proteins. Conclusions: It is economic, eco-friendly and deserves major share in hospital disinfection.

Presence of Qnr genes related to resistance to quinolones, first-, second- and third-generation in diarrhoeagenic Escherichia coli
Abbas Mokhtari-Farsani, Abbas Doosti, Zahra Mohammadalipour
January-December 2016, 4(1):5-9
Background: Resistance genes transferred by plasmids are important factors that can contribute to the occurrence of quinolone resistance, specifically in Escherichia coli strains. Methods: A total number of 117 diarrhoeagenic E. coli strains were tested for the resistance to nalidixic acid, ofloxacin, ciprofloxacin and levofloxacin and for the presence of qnrA, qnrB and qnrS genes determinants by polymerase chain reaction. Antibiotic susceptibility test was performed using the Clinical and Laboratory Standard Institute standard method. Results: The highest resistance belonged to the nalidixic acid (52.14%) and the least resistance to levofloxacin (37.61%). In this study, among a total of 117 samples, 23 (19.66%) strains were susceptible to all the studied antibiotics. Among the remainder, 94 (80.34%) samples resistant to at least one quinolone, three genes including qnrA, qnrB and qnrS were present in 19.15%, 88.30% and 78.72% isolates, respectively. Furthermore, 51.06% of strains had A, B+ and S+ pattern that seems to have a significant association (P < 0.001) with resistance to quinolones. Conclusions: The results of present study show the presence of a high frequency of qnr genes in E. coli strains resistant to quinolones in clinical samples from southwest of Iran. In addition, this study approved that plasmid-mediated quinolone resistance is a possible mechanism among the quinolones-resistant E. coli isolated from patients with diarrhoea in the study, and also qnrB and qnrS genes seem to be more important in resistance to quinolones.

Priyam Batra, S Thomas, Jacinta Gunjyal, Purva Mathur, Babita Gupta, Chhavi Swahnney, Deepak Agarwal, Ashish Bindra, Keshav Goyal, Richa Aggarwal, Kapil Soni, Rajesh Malhotra
May-August 2018, 6(2):59-62
Introduction: Central venous catheters are vital in critical care which can be associated with infectious and non-infectious adverse events. Materials and Methods: This case–control study was conducted over 1 year in trauma centre of India. All patients admitted in intensive care units (ICUs) having central line inserted during the study period (November 2013–October 2014) were included as cases. Historical controls with non-antibiotic-impregnated dressings were used as controls (November 2012–October 2013). Standard central line insertion and maintenance checklist was followed. Results: A total of 2034 patients were admitted in ICUs during study period, and the central line-associated bloodstream infection (CLABSI) rate was 2.89/1000 catheter days. During the year 2012–2013, 2100 patients were admitted and CLABSI rate was 3.04/1000 catheter days. The mean central line insertion bundle compliance rate was 76.8% in 2012–2013 and 78.37% in 2013–2014. The compliance with scrubbing the access port was minimum 34% while that with change in dressing was the maximum 79%. Discussion: Since CLABSI rate reduction was not statistically significant, the use of biopatch in our setting could not be justified and its use was not found to be cost-effective. In maintenance bundle, compliance with scrubbing the hub was least only 35%. Thus, the use of effective maintenance bundle parameters could easily reduce CLABSI rate.

Chithra Valsan, Jane Paul, Praveenlal Kuttichira, Resmi Varghese, Sophiya Joseph
May-August 2017, 5(2):47-51
Background: Health-care workers (HCWs) are always at risk of occupational exposures (OEs) to bloodborne pathogens which mostly occur through needlestick injuries (NSIs). Knowledge about the magnitude and profile of such incidents in a hospital can help to plan effective intervention strategies to reduce such mishaps. Objectives: This study was carried out to find out the magnitude and trends in OE that had occurred in the past 2 years to the HCWs of our hospital which is an 1800 bedded centre to plan effective strategies for the prevention of such incidents. Materials and Methods: An observational study was carried out by collecting data on OEs among our HCWs in the past 2 years from the OE register maintained by the Hospital Infection Control Committee. The circumstances at which these incidents occurred also were analysed. Results: A total of 172 incidents were reported of which 161 (93.6%) were NSIs and 11 (6.4%) splashes. Nurses sustained highest number (38.95%) of NSIs, and maximum incidents occurred in the medical wards (34.9%) and the morning shift (51.3%). Majority (43.6%) occurred during recapping of needles. Discussion and Conclusion: NSIs occur in all categories of HCWs. A multilevel approach that includes regular awareness programmes that can bring about changes in attitude, strict waste management policies and innovative needles and syringes can reduce such incidents.

There is more to hand hygiene than routine training of health workers and display of promotional materials
Ashmitaa Srianand, Marina Thomas
January-December 2016, 4(1):1-4
Background/Objective: Hand hygiene (HH) non-compliance is a major cause of hospital-acquired infections, and a gap between knowledge and practice is observed widely. Health researchers are now using a new approach called 'Positive Deviance' (PD) to tackle such behavioural/cultural/social problems leading to adverse health issues. Therefore, can PD approach be used to improve knowledge and compliance of HH practices also? This study is designed to find what are the reasons for PD among nursing staff of our hospital and whether these behavioural changes can be imbibed by others if motivated and trained appropriately. Materials and Methods: The level of compliance to HH and PD among 25 Intensive Care Unit nurses was noted. This was followed by a second and a third interface consisting of focus group discussions and one-to-one interviews to motivate them based on the PD noted and to detect the possible betterment of compliance to HH. Results: The practice of HH was followed by 20% of the nurses, and they were identified as positive deviants and when reasons which made them to be compliant were reinforced and impressed on the rest of the nurses, a further 32% became compliant. Awareness of the fact that HH prevents colonisation with potential pathogens was shown by 100% after the intervention. Conclusions: A PD strategy yielded an improvement in HH compliance. An improvement in knowledge and practice of HH was noted. Multimodal interventions are needed to induce sustained HH practice improvements and this will reduce the gap between knowledge and practice of HH in hospitals and thereby reduce hospital-acquired infections.

Blood culture contamination rates in two district general hospitals in the Southeast of England
Nadeem Sajjad Raja, Bill O'Neill
May-August 2017, 5(2):57-61
Introduction: Blood culture is considered an important diagnostic tool to identify the causative agent of bloodstream infection (BSI) as well as to direct the definitive therapy. High contamination rate in any healthcare institution is directly linked with increased cost, use of unnecessary antibiotics and additional testing in the diagnostic laboratories. The audit team determined the blood culture contamination rate and the distribution of microorganisms causing BSIs in patients for the East Sussex Healthcare Trust, United Kingdom. Materials and Methods: This is a retrospective study which analyses the blood culture results over 2 years period (January 2014 to December 2015). Positive blood cultures were grouped into significant, contaminant or unknown significance by reviewing patient clinical data collected at the time of positive blood culture and the microbiology records. Results: A total of 11036 blood cultures were processed in the microbiology laboratory during the study (January 2014 to December 2015). A total of 1641 (14.9%) blood cultures were positive. Of 1641, 1298 (11.8%) and 286 (2.6%) were grouped as significant and contaminant, respectively. Fifty-six positive blood culture sets remained indeterminate due to the lack of the clinical information. The overall contamination rates in both hospitals in 2014 and 2015 were 0.9% and 1.7%, respectively. The average yearly contamination rate is 1.3%. Higher contamination rates were recorded from the paediatric, emergency, orthopaedics and surgical departments. A total of 1753 microorganisms were isolated. The most common isolated organisms include Escherichia coli 482, (27.5%), Coagulase-negative Staphylococcus, 274 (15.6%), Streptococcus species, 183 (10.4%), Staphylococcus aureus, 162 (9.2%), Klebsiella species, 135 (7.7%), Enterococcus species, 109 (6.2%) and Streptococcus pneumonia, 48 (2.7%). Thirty-three Candida species were isolated. The prevalence of methicillin-resistant S. aureus and the extended-spectrum b-lactamase producing Enterobacteriaceae were low. Conclusion: The present data showed lower contamination rate in the Trust than the acceptable rates. It also supports the need for regular training and education of healthcare professional that collect blood culture where the contamination rates are high.

Areena Hoda Siddiqui, Vipul Kumar Srivastava, PP Aneeshamol, Carolyn Prakash
January-December 2016, 4(1):22-24
Background: In the era of multidrug-resistant organisms and dearth of new antimicrobials, hand hygiene has become an important tool in reducing the burden of healthcare associated infections (HAIs). The content of this article is based on awareness and practice of hand hygiene among healthcare workers (HCWs). Objectives: Hand hygiene has emerged as one of the most important strategies to prevent HAIs. Hand hygiene practice has led to the decrease in infections. The present study was undertaken to assess the compliance among HCWs. Materials and Methods: Hand hygiene compliance and number of opportunities were evaluated for 2 years (2013 and 2014), and the data were compared. The study was carried out in the emergency department and critical care areas of our hospital. Results: It was found that the number of events monitored and compliance increased considerably in the subsequent year. The compliance rate on an average increased from 57.6% to 61.6%. Conclusions: The present results emphasise on the regular training and education of hand hygiene among HCWs. They should be made aware of the HAIs and that hand wash and hand rub help in decreasing the rate of HAIs.

Prevalence of surgical site infections and antimicrobial sensitivity pattern in patients attending a Tertiary Care Hospital in South India: A prospective study
Giridharan Shanmugam, Selvi Rangam, KK Kayalvili, Lakshmi Sundaram
January-April 2017, 5(1):12-17
Background: Nosocomial infections account for 1.7 million cases every year costing between $35.7 billion and $45 billion of losses to the system and surgical site infections (SSIs) were responsible for 77' of the death of patients. This study aims to analyse the factors involved and thereby reduce them. Materials and Methods: Ninety-six patients undergoing both emergency and elective procedures in the surgery department during a period of 1 month were selected and followed up pre-operatively, intraoperatively, post-operatively and till 30 days after surgery. Results: The prevalence rate of SSI was 41.6' with women (52') and patients of the age group of 41–60 years (30') being affected more. Alcohol, smoking, tobacco use, diabetes, hypertension, tuberculosis, duration of surgery hospital stay and the American Society of Anesthesiologists classification proved to be important factors in the prevalence rate. Emergency surgeries had twice the rate than electives. Staphylococcus aureus (22') and Escherichia coli (22') followed by Pseudomonas aeruginosa (18') and Proteus mirabilis (17') were the organisms isolated. All S. aureus isolates were methicillin sensitive but erythromycin resistant. E. coli isolates were sensitive to the antibiotics except for cefotaxime and ampicillin (41.6'). Pseudomonas showed resistance to bacitracin (80') and ampicillin (90'), and all were sensitive to ceftazidime. The Proteus species were all resistant to cefotaxime. Conclusion: The high prevalence rate in the study can be reduced by following a systematic approach during pre-operative workup of the patient with proper pre-operative hair removal and smoking cessation at least 1 month before surgery and post-operative monitoring and educating the patient.

Sanjay Kumar Gupta, Sunitha Lorin Mathias, Ibrahim Saifi Al Harbi
May-August 2017, 5(2):52-56
Introduction: Hand hygiene (HH) is now considered as one of the most important measure of infection control activities. In the time of the growing burden of health care associated infections (HCAIs), the increasing severity of illness and complexity of management, threatened by multi-drug resistant (MDR) pathogen infections, health care workers (HCWs) are reversing back to the basics of infection preventions by simple measures like hand hygiene. Objectives: To find out the hindrance or obstacles in hand hygiene practice among health care workers. Methodology: Hospital based cross sectional study. Observation's: In the present study we asked about their opinion about hand hygiene (HH) around 21(28%) responded were fully correct, we also access their correct knowledge about WHO five moments/ indication of hand hygiene (HH) 70 (94%) had correct knowledge regarding indication of hand hygiene. We also access according to their day to day difficulties/obstacles in hand hygiene practice majority of them responded often too busy or insufficient time 18 (25%) followed by hands don't look dirty and skin irritation 17 (23%) & 17 (23%) respectively, some peoples also influenced by others behavior because they don't practice so we 13 (17.56%) also responded no difficulties in practicing hand hygiene (HH) in day to day work. We also asked their suggestions for improvement in hand hygiene compliance among health care workers majority of them suggested encourage the staff to do hand hygiene practice every now and then. Conclusion: Most of the respondents in present study were young females, most common obstacle in hand hygiene practice was often too busy and hand don't look dirty. Common suggestion for improvement was head of unit should ask to staffs daily in morning meeting about hand hygiene compliance and those who not follow after all these efforts to be punished.

Risk stratification of surgical site infection in a Tertiary Care Hospital: A prospective case-control study
Murali Chakravarthy, Sukanya Rangaswamy, Antony George, Tejaswini Anand, Priyadarshini Senthilkumar, Suganya Arul Rose
May-August 2017, 5(2):73-77
Introduction: Health care associated infections are preventable cause of morbidity and mortality in healthcare setting. Surgical site infections are no different. It is essential to identify patients who are at high risk of getting SSI and preventive measures instituted even prior to admission for surgery Methods: This study comprising of all the SSIs that we encountered over two years and about 10 to 12 patients (per infected patient ) without infection as 'controls'. These two sets of data was used to identify the weightage of each risk factor using logistic regression. Results: We encountered thirty infections during the years 2015 and 2016, three hundred thirty non infected cases were used as control to arrive the weightage of each factor. Using a backward stepwise multivariate logistic regression model in the whole cohort, body mass index > 30 kg/m2, duration of preoperative stay and use of preoperative antiseptic shower were found to be independent predictors for SSIs. We could predict incidence of SSI with good discrimination (area under ROC curve – 0.855 , 95% confidence intervals 0.81-0.89). Three factors appear to stand out in our study, they are BMI, preoperative stay and preoperative antiseptic shower. These factors appeared to weigh differently in each specialty. Conclusion: The authors are now able assign scores to each of their patients depending on the type of surgery, sex of the patient, body mass index, number of preoperative days in the hospital, and whether chlorhexidine shower was given or not.

A cross-sectional pilot survey of sharp injuries among dental students in a tertiary care dental hospital in Lucknow, India
Rhythm Bains, Vivek K Bains, Reema Kumari
September-December 2018, 6(3):78-82
Aim: This study aims to estimate the frequency of sharp injuries among the post-graduate and undergraduate dental students and evaluate their knowledge regarding the needle-stick/sharp injuries, proper handling and disposal of sharp waste. Methodology: A written questionnaire containing questions regarding frequency of sharps injury, source of injury, status of immunisation and knowledge regarding handling and disposal of sharps waste was personally distributed to the participants and collected on the same day. Informed consent was obtained from the participants, and the purpose of the study was explained to them. The data obtained was statistically analysed. Percentage distribution of responses for Bachelor of Dental Surgery (BDS) and Master of Dental Surgery (MDS) students was recorded. Furthermore, the comparison of responses for BDS and MDS was analysed using the t-test. Chi-square test was used to find the significance difference between responses by BDS and MDS students. Results: The results of the present questionnaire study revealed that 38.5% (10/26) post-graduate students and 37.2% (16/42) undergraduate respondents had a history of sharps injury (P = 0.917). Most common reason for the injury among post-graduates was recapping of needles 84.6% (22/26) followed by endodontic instruments 11.5% (3/26) and use of probes/explorer 3% (1/26). Among the undergraduates, the most common source of injury was again recapping of needles 97.7% (42/43), followed by endodontic instruments 2.3% (1/43). Conclusion: Both undergraduates and post-graduates reported with history of sharps injury, though the difference among them was not significant. Needle-stick or sharps injury can prove to be fatal, and as dental students have an early clinical exposure, they should be trained early in their curriculum regarding correct disposal and handling of sharps.

Manipriya Ravindran, Sivasundari Gowtham, Priyanka Mehta, Palaniappan Narayanan
May-August 2017, 5(2):69-72
Background: Pregnancy is an immunocompromised state where in infections are common. H1N1 (hemagglutinin type 1 and neuraminidase type 1) Influenza is a seasonal epidemic, considered as an alarming infection across the world with high rates of maternal mortality each year. The principal intention of this study was to elicit the clinical profile of antenatal mothers with H1N1 and subsequently to analyse the risk factors, prognosis and the materno-fetal outcome. Extensive review of literature with current guidelines and management protocols has been highlighted. Methodology: This is a retrospective observational study performed in Sri Ramachandra University and Research Institute over the period of one year from January 2016 – March 2017, the clinical course of the patients who were confirmed with H1N1 influenza using throat swab RT-PCR assay was analysed. Statistical analysis was done by SPSS, version 11. Results: A total of 62 antenatal patients with symptoms suggestive of H1N1 influenza were tested for H1N1 out of which 12 were positive, which accounted for 19.35% positivity. The mean age was 24 years with a range of 22-30 years. The epidemic peaked in the month of November to January. Fever with cough was the most common clinical manifestation. Most of the patients were hospitalized and treated with oseltamivir. All the positive patients, were advised home isolation for 5-7 days after discharge. This indexed study had an overall mortality rate of 8.3%. Acute respiratory distress syndrome and multiple organ dysfunction were the most common cause of death. Conclusion: Most of the patients recuperated well with close vigilance, symptomatic and antiviral treatment, went on to deliver healthy baby. Proper prevention steps, personal hygiene and admission to designated swine flu ward can be helpful in preventing the spread in the community. Respiratory failure and sepsis were the cause of mortality among the patients of this study.

Sanjay Kumar Gupta, Fahd Khaleefah Al Khaleefah, Ibrahim Saifi Al Harbi, Marilou A Torre, Sinimol Jabar, Sunitha Lorin Mathias, Omar Al Romaih
January-April 2018, 6(1):27-31
Background: Ventilator-associated pneumonia (VAP) is defined as pneumonia that occurs after 48—72 h following endotracheal intubation, characterised by the presence of a new or progressive infiltrate showing in X-ray, signs and symptom of systemic infection such as fever, change in white blood cell count, changes in sputum characteristics and the detection of a causative agent in the sample. Aim: This study aims to find out the epidemiological pattern of the VAP in Intensive Care Unit and their sensitivity pattern. Materials and Methods: This was retrospective observational study. Results: In the past 5 years, 69 (20.24%) cases of VAP were reported out of total healthcare-associated infections (n = 331). The male cases 54 (78%) were nearly four times higher than that of female cases 15 (22%), and difference is statistically significant (χ2 = 15.2, P = 0.01). Most of the cases observed were above 60 years of age (n = 24) whereas, least cases observed in cases below 15 years of age (n = 4). In the present study, VAP was observed in increasing trend (2012—2015) 16% to 27%. Mean hospital-wide infection rate was higher in 2015 (4.34; standard deviation [SD] =3.33) than 2016 (2.14; SD = 2.25). The most common organism isolated from VAP was Acinetobacter baumannii followed by Pseudomonas aeruginosa. Conclusion: The VAP cases reported four times higher among males than females and common above 60 years of age, most common causative organism isolated from VAP patients was A. baumannii. Majority of the isolates of A. baumannii and P. aeruginosa were resistant to commonly used antibiotics.

Vijeta Bajpai, Deepak Gupta, Ashish Bindra, Rajesh Malhotra, Purva Mathur
January-April 2018, 6(1):23-26
Introduction: Antibiotic stewardship practices require that antimicrobial treatment should be tailored according to microbiological culture. Therefore, the aim of this study was to describe the antibiotic prescription pattern and to assess how frequently the surgeons request for a specimen culture during the patient's stay. Materials and Methods: This was an observational study; conducted in level-1 trauma center for 10 months and all consecutive neurosurgery patients, admitted in the hospital were included in the study. Detail of microbiology culture and anti-microbial-sensitivity results were recorded. Antibiotic prescriptions were recorded in each patient during their hospital stay. Results: A total of 1216 consecutive patients admitted to the neurosurgery unit were included in the study. The mean age (± standard deviation) of patients was 33.29 (±16.27) years, predominantly male patients; 1038 (85.4%). Overall, culture-confirmed infections were present in 216 (19.4%) patients. Prevalence of Gram-negative bacteria; 195 (90.2%) was more than Gram-positive bacteria; 21 (4.7%) (P < 0.001). The most frequently used antibiotic was cephalosporin; 1030 (84.7%), followed by aminoglycoside; 952 (78.3%), fluoroquinolone; 422 (34.7%), penicillin; 311 (25.6%) and metronidazole 277 (22.8%). A total of 400 (13.15%) antibiotics were prescribed appropriately in patients with culture-confirmed infection while 2640 (86.8%), antibiotics were given inappropriately in rest of the patient in whom there was no matching culture-confirmed infection (P < 0.001). Conclusion: A very small number of antimicrobial prescriptions were based on culture reports. Hospitals in developing countries including India need to institute surgical antibiotic policies soon since most hospitals are facing a severe problem of antimicrobial resistance.

January-April 2018, 6(1):19-22
Introduction: Mobile phones have become an inevitable mode of communication. Dental office and the dental operators along with their mobile phones are exposed to numerous pathogens as a part of their profession, leading to nosocomial infection. This study aimed at assessing the effectiveness of isopropyl alcohol and a customised ultraviolet-based (UV) sanitiser in decontamination of mobile phones. Methods: A cross-sectional study was carried out on 30 touch screen mobile phones belonging to dental professionals in a college setting. Swabs were collected along the screen, camera lens and on/off buttons of mobile phones. Swabs were streaked onto nutrient agar and incubated at 37°C for 24 h for the assessment of microbial load before and after the disinfection procedures. The disinfection process was performed using 70% isopropyl alcohol and an UV-based sanitiser. Mann—Whitney U-test was used to compare the values between the two groups. Wilcoxon signed-ranks test was used to compare values within each group Results: There was a statistically significant reduction in the mean number of colonies (P = 0.001) after decontamination by the two groups (isopropyl alcohol and UV-based sanitiser) indicating that both agents were effective in disinfection. Conclusion: The study concluded that the percentage reduction in microbial load of the mobile phones was better with isopropyl alcohol compared to UV-based sanitiser. It is recommended that mobile phones in the dental setup be regularly decontaminated and dentists must adhere to strict infection control protocols specifically in relation to hand hygiene.

Bacterial spectrum and antimicrobial-resistance pattern of bloodstream infections in neutropenic and non-neutropenic adult cancer patients
Nadeem Sajjad Raja, Sunil Gupta, Bill O'Neill
May-August 2017, 5(2):83-88
Background: Bloodstream infections (BSI) in cancer patients remain associated with significant morbidity and mortality. The choice of an empirical antibiotic regimen is usually based on the local epidemiology of the microorganisms and their antimicrobial susceptibility profile. We present the spectrum and the antimicrobial susceptibility of the causative agents of BSI in adult cancer patients in East Sussex Healthcare Trust (ESHT), UK. Materials and Methods: This retrospective study was conducted at ESHT from January 2006 to December 2015. Demographic and laboratory data were collected from the pathology information system. Results: A total of 640 episodes of BSI occurred in 297 patients (159 male). Of the 297 patients, 239 (80%) had haematology malignancies, whereas 54 (18%) had solid organ tumours. Four patients had both. Majority of BSI (383, 60% episode) occurred in neutropenic patients. A total of 802 organisms (477 [59%] and 325 [41%] organisms from neutropenic and non-neutropenic patients, respectively) were isolated. Of 802, 406 (51%) Gram-positive and 386 (49%) Gram-negative organisms were isolated. Seven Mycobacterium species and three Candida species were isolated. Most common organisms in neutropenic patients were coagulase-negative Staphylococcus (CoNS) (22%), Klebsiella species (14%), Escherichia coli (13%), Streptococcus species (10%) and Pseudomonas species (10%). In non-neutropenic patients, CoNS (29%), E. coli (11%), Pseudomonas species (8%), Streptococcus species (7%) and Klebsiella species (5%) were isolated. Twelve glycopeptide-resistant Enterococci (26% of total 47 Enterococcus species) were isolated. Four methicillin-resistant Staphylococcus aureus (14% of total 28 S. aureus) were isolated. Furthermore, 15 extended-spectrum β-lactamase producing Gram-negative bacilli were isolated. Among Gram-negative organisms, more than 91% isolates were sensitive to piperacillin/tazobactam, ceftazidime and ciprofloxacin and higher sensitivity rates (>95%) were recorded in gentamicin, polymyxin B and meropenem. Conclusion: This study highlights an ongoing trend towards Gram-positive organisms causing BSI in cancer patients. The antimicrobial regimens used in our institution are highly effective against commonly isolated organisms. The identification and the antimicrobial susceptibility of the microorganisms causing BSI in cancer patients remain important to develop antimicrobial treatment strategies including antimicrobial guidelines as well as infection control and to prevent the spread of antimicrobial resistance.

Objective: Healthcare associated infections cause significant morbidity, mortality and escalation of cost of care. It is the responsibility of all concerned to work towards reducing this potentially preventable increase in morbidity, mortality and cost caused by healthcare associated infections. Such data in Indian subcontinent has been studied sparingly. The objective of this study was to understand the degree of the cost escalation, morbidity and mortality associated with healthcare associated infections. Design: This prospective case controlled observational study was carried out from the year 2007 onwards. All the infections that occurred unto 2014 were included. Cost, morbidity and mortality of two similar matched controls for each infected case were chosen. Setting: Tertiary referral hospital. Participants: All patients with healthcare associated infections and twice that number as control. Interventions: None. Main outcome measure: Escalation of cost, morbidity and mortality due to healthcare. Results: There were five hundred fifteen infections during the study period. The escalation of cost due to infection was $ 4611. The mean mortality in the infected group was 8.75% in contrast to 2.5 in the non infected group. The mortality due to central line associated blood stream infection and ventilator associated pneumonia was more than 30% each. The length of stay in the intensive care unit was 8 days in the infected group in contrast to 2.27 days in the non infected group. Length of stay in the hospital was 33.5 days in the infected patients in contrast to 10.3 days in the non infected group. Conclusions: Healthcare associated infections caused escalation of cost, length of stay in the intensive care unit and hospital. Mortality in the infected cohort was more in contrast to the controls.

Background: Surgical site infections (SSIs) still continue to be a major cause of morbidity and mortality despite the improvement in methods for infection control as well as surgical practices. The aim of this work is the presentation and analysis of SSI control practices in selected surgical wards in Poland as compared to other European countries. Methodology: The presented data were obtained using a standardised questionnaire within a European project devoted to describing and analysing the surveillance of nosocomial infections in individual European countries. Results: In all studied wards, written procedures of SSI prevention were present, as well as obligatory training of ward personnel concerning infection control. Alcohol-based hand rub dispensers were available in over 75% points of care in most wards, as opposed to belt/pocket bottles, which were available for a small number of ward personnel. Alcohol solutions were most often used for skin preparation. Shaving immediately before operations was the most common way of hair removal. A WHO checklist was used in 20% of the studied wards. Conclusions: Based on the results of the study, the organisation of surveillance infections in Polish surgical wards appears to be satisfactory. However, practical implementation of SSI prophylaxis calls for significant alterations, both in terms of executing training and implementing practices in the wards or the operating room. On the one hand, due to a lack of multicentre studies on the epidemiology of SSI in Polish surgical wards, actual exposure to SSI cannot be assessed.
