Comparison of hand hygiene compliance among healthcare workers in Intensive care units and wards of COVID-19: A large scale multicentric study in India.

BACKGROUND: Hand hygiene is a significant component involved in preventing transmission of health care associated infections including COVID-19. Compliance to hand hygiene among the health care workers (HCWs) requires evaluation and timely feedback. "You can't improve what you can't measure" is a famous saying and this multicentric study was designed to measure hand hygiene compliance and have birds eye view on hand hygiene compliance in COVID Intensive care units (ICUs) and wards across India. METHODS: A prospective multicentric observational study was conducted for a period of 6 months in 92 health care facility across India which included varied type of public and private hospitals. Hand hygiene audit was conducted in COVID ICU and COVID non-ICU wards in all these facilities by their HCWs using the IBHAR mobile application based on WHO's hand hygiene audit tool. Hand hygiene total adherence rate (HHTAR) and hand hygiene complete adherence rate (HHCAR) were analyzed and compared between 2 locations. Adherence rates were analyzed based on the zones, institute type, profession and for each WHO moments. RESULTS: A total of 1,61,056 hand hygiene opportunities were documented and adherence rates were recorded higher in COVID wards (HHTAR-61.4%; HHCAR-28.8%) than COVID ICUs (HHTAR-57.8%; HHCAR-25.6%). Overall, the adherence rates were observed higher in COVID wards (HHTAR- 68.1%; HHCAR-38.3%) of private hospitals, COVID wards of the west zone (HHTAR- 70.2%; HHCAR-36.8%), cleaning staffs of the COVID ward scores better compliance than all other professions in COVID ICUs and COVID wards. HHTAR was found to be the higher in moment 3 (After body fluid exposure-76.3%) followed by moment 4 (after touching patient-73.7%) done in COVID wards compared to moments done in ICUs. CONCLUSIONS: This study highlights the practice of hand hygiene in COVID care locations across India. Effective strategies need to be implemented in COVID ICUs across the facilities to improve the compliance.

Impact of conducting hand hygiene audit in COVID-19 care locations of India-A large scale national multicentric study - HHAC study.

PURPOSE: Hand hygiene (HH), the core element in infection prevention in healthcare, especially for multidrug resistant organism's transmission. The role of HH audits and HH adherence rates in the COVID-19 pandemic, especially in resource limited settings, are yet to be established. METHODS: A nationwide multicenter study was conducted in India, involving public, private, teaching and non-teaching COVID healthcare facilities (COVID-HCFs) using the IBhar mobile application based on WHO's hand hygiene audit tool. The HH adherence rates (HHAR) such as complete HHAR (HHCAR), total HHAR (HHTAR), profession specific HHAR, WHO's 5 HH moment specific HHAR and associated variables were measured over 6 month duration (June-December 2021). RESULTS: A total of 2,01,829 HH opportunities were available and the HHCAR and HHTAR were 27.3% and 59.7%. The HHTAR was significantly higher in the west zone (72.2%), private institutes (65.6%), non-teaching institutes (67.7%), nurses (61.6%), HH moments 2 (71.8%) and 3 (72.1%), and morning shift (61.4%). The HHTAR was better in non-COVID HCFs (65.4%) than COVID-HCFs (57.8%) as well as non-COVID ICUs (68.1%) than COVID ICUs (58.7%). The HHTAR was increased from month 1 to month 6 except a small decrease in the month of December. CONCLUSIONS: The hand hygiene adherence is comparable with adherence rate during COVID-19 pandemic in western countries as well as the resource limited settings. The use of gloves during the pandemic and simplified HH techniques and their influence over the HH adherence to be studied further. The sustainable adherence rate over long duration needs to be ensured by continuing the HH audit using multimodal interventions.

Effectiveness of Multimodal Intervention to Improve Blood Culture Collection in the Emergency Department.

Introduction: The blood culture (BC) contamination was a significant problem in our hospital, especially in the emergency department (ED). The study, therefore, was undertaken to improve the BC collection in the ED. Methods: The study was conducted for 1 year divided into two phases of 6 months each: Preintervention phase and intervention phase (regular and phlebotomist groups). The interventions comprised implementing standard protocol for BC collection and conducting educational sessions. In preintervention and regular groups, the BCs were collected by interns and technicians, while dedicated phlebotomist did so in the phlebotomist group. Data were analyzed and interpreted for the contamination rate as well as compliance in adequate filling of the requisition form. Statistical Package for the Social Sciences (SPSS) version 22. A value of P < 0.005 was considered statistically significant, and P < 0.01 was considered statistically significant. Results: In the preintervention group, 13.7% of specimens were reported as contaminated which was reduced to 4.2% and 3.2% in the regular and phlebotomist group, respectively, after intervention. Compliance of health-care workers to various elements of BC collection protocol was also found to be significantly improved in the intervention phase compared to the preintervention phase (P < 0.001). Conclusions: Implementation of this multimodal intervention resulted in a drastic reduction in BC contamination and improvement in compliance to BC collection protocol and filling of various parameters in the BC requisition form, thus improving the overall effectiveness of BC testing. It was also noted that the contamination rate was further reduced by implementing dedicated phlebotomist.

Clinical profile, visual outcome and root cause analysis of post-operative cluster endophthalmitis due to Burkholderia cepacia complex.

PURPOSE: To present varied clinical presentations, surveillance reports, and final visual outcomes of a rare outbreak of cluster endophthalmitis caused by gram-negative, opportunistic bacilli, Burkholderia cepacia complex (Bcc). METHODS: Details of five patients who developed postoperative cluster endophthalmitis were collected. For each patient, an undiluted vitreous sample was collected during vitreous tap. Bacterial culture from the vitreous sample in each case had grown Bcc. Surveillance investigations for root cause analysis (RCA) were performed in the operating room (OR), admission, and day-care wards to localize the source. RESULTS: Four patients had undergone phacoemulsification surgery, and one patient had undergone penetrating keratoplasty. Each patient received an initial dose of empiric intravitreal ceftazidime and vancomycin. The organism isolated in each case was sensitive to ceftazidime, cotrimoxazole, and meropenem and resistant to other antibiotics. Core vitrectomy was done after 48-60 hours in four patients along with intravitreal imipenem injection. One patient did not provide consent for core vitrectomy and subsequently developed phthisis bulbi. Three patients had subsequent recurrences. Two patients had a final BCVA of 20/60, two had BCVA better than 20/200, while one patient had no perception of light. None of the surveillance samples from the OR complex could isolate Burkholderia. CONCLUSION: Extensive OR surveillance should be done to identify the potential source of infection. However, the source may not be identifiable in few instances like in our case. Longer follow-up is recommended in cases of Bcc endophthalmitis due to the persistent nature of the infection.

Increasing Trend of Vancomycin-resistant Enterococci Bacteremia in a Tertiary Care Hospital of South India: A Three-year Prospective Study.

Introduction: Vancomycin-resistant enterococci (VRE) are emerging as an important multidrug-resistant pathogen causing nosocomial infections, predominantly bacteremia and urinary tract infections. VRE bacteremia has caused a significant increase in the duration of the hospital stay and mortality and had caused high public health threat due to limited treatment options. Materials and methods: Between October 2017 and September 2020, all consecutive patients with culture-proven bloodstream infection with Enterococcus species, isolated for the first time, were included in the study. A total of 427 Enterococcus species were identified, and antimicrobial susceptibility tests were performed and interpreted using Clinical and Laboratory Standard Institute guidelines. Results: Of the total 427 Enterococcus species isolated, 63 (45.6%) were VRE. Among them, 51/63 (81%) were Enterococcus faecium (E. faecium) and 5/63 (8%) were Enterococcus faecalis. There was an increased trend of VRE rate in the bloodstream infections of 6.12% (2018), 13.2% (2019), and 19.2% (2020). The majority of the VRE patients [43/63 (68%)] were admitted to the intensive care units (ICUs). Vancomycin A (VanA) is the most common phenotype isolated from 51/63(81%) patients. Conclusion: This increasing trend of VRE bacteremia is a red alert to the clinicians and the infection control practitioners, so that strict antibiotic policies and proper adherence to the infection control practices can be initiated to reduce the VRE rate.

Burkholderia cepacia infection in a non-cystic fibrosis patient: an arcane presentation.

INTRODUCTION: Burkholderia cepacia is an aerobic, Gram-negative bacillus, which exhibits innate resistance to multiple antibiotics and disinfectants. Although it is a chronic colonizer of the respiratory tract, it may rarely present with fatal necrotizing pneumonia-like features in immunosuppressed individuals, as those with chronic granulomatous disease, or patients with significant pulmonary compromise, like cystic fibrosis. CASE PRESENTATION: A 76-year-old male presented with complaints of breathlessness, cough with mucoid expectoration and fever for 3 days. He had a history of coronary artery disease, chronic obstructive pulmonary disease (COPD), diabetes mellitus and hypertension, under treatment. Pulmonary function tests were suggestive of very severe obstruction (FEV1/FVC was 55 %). So, clinical diagnosis of acute exacerbation of COPD was established. Sputum culture grew B. cepacia . The patient was treated with ceftazidime and meropenem along with inhalational bronchodilators and steroids, and showed symptomatic response to therapy. CONCLUSION: There is paucity of the literature describing B. cepacia as a potential cause for acute exacerbations in relatively common clinical conditions, such as COPD. This case report highlights the speculation of this rare possibility, thereby alerting a clinician dealing with such cases.

Clinical outcomes of suspected Catheter Related Blood Stream Infection at a tertiary care center in south India.

BACKGROUND: Catheter related blood stream infection (CRBSI) makes up a significant proportion of Hospital acquired infection and increases the morbidity and mortality of those affected. AIMS AND OBJECTIVES: Primary aim was to study the clinical outcomes of patients with suspected Catheter Related Blood Stream Infection (CRBSI). RESULTS: Of the 150 participants suspected of having CRBSI, 100(67%) had CRBSI, 26(16%) patients were colonizers and 24(17%) patients had BSI from another source. Gram negative microbes were predominant. Clinical outcomes were studied with respect to mortality, complications and length of hospital stay. CRBSI participants had a significantly prolonged hospital stay. However no specific factors related to the host or the pathogen influenced this outcome. CONCLUSION: CRBSI prolongs the hospital stay for patients who would have otherwise been discharged, hence increases the burden on hospital and human resources.

A pilot study to evaluate urine LAM assay for diagnosis of pulmonary tuberculosis among non-HIV patients.

There is a great need to improve diagnostic tools for tuberculosis where the majority are without HIV co-infection in resource-poor settings and high-burden areas such as India. The urine LAM assay has not hitherto been studied and may have a role to play. Our study found that, as a stand-alone diagnostic tool, the assay was suboptimal when compared to Xpert MTB/Rif. However, a combination of LAM assay along with sputum microscopy may be useful in settings where molecular testing is unavailable.
