Biomedical waste segregation compliance scoring system: to analyze, strengthen, monitor, and step up waste management in healthcare facilities.

Introduction: segregation of biomedical waste (BMW) is the foremost and prime step for effective BMW management. This study was taken up to assess the BMW segregation compliance in patient care areas using a checklist-based scoring system to analyze the segregation compliance and establish feedback-based training programs. Methods: this study was conducted between January 2020 to December 2021 at a government tertiary care hospital in Hyderabad. The compliance was calculated by giving a score of one for each day, such that if there was no noncompliance (NC) the score was 100% for a given location at the end of the month. A score of minus one was given for each day a noncompliance was noted and transfigured into percentages. A score of 100% was considered good, and below 95% was considered an action point necessitating root cause analysis and training. Results: the BMW segregation compliance scores of the hospital for the year 2020 (96.5%) were compared with 2021 scores (97.5%). The outpatient department (OPD) and ICU had the poorest compliance rate of 93.7% and 93.6% respectively, compared to wards (96.2%). The most common factors influencing NC in BMW segregation were the joining of new staff, relocation, or new establishment of wards. The most common segregation error was found in the yellow disposal bags pertaining to the disposal of personal protective equipment. Conclusion: this easy and simple scoring system was established to improve the segregation compliance of BMW. End of each month an area wise compliance is easily made such that areas with low scores could be trained.

Continuous ambulatory peritoneal dialysis peritonitis: Microbiology and outcomes.

Context: Continuous ambulatory peritoneal dialysis (CAPD) is now a preferred mode of the treatment in patients with end-stage renal disease, but peritonitis remains to be a shortcoming of CAPD. High-culture negativity, emerging drug resistance and peritoneal dialysis (PD)-related morbidity and mortality have been a challenge to tackle. Aims: The present study was taken up to compare the the various culture methods and to identify the spectrum of organisms causing CAPD peritonitis and their outcome. Settings and Design: A prospective, observational, cross-sectional study was conducted at a tertiary care teaching hospital in Hyderabad over a period of 1 year. Subjects and Methods: Dialysate fluid from 100 episodes of clinically suspected peritonitis in 75 patients was processed by conventional centrifuging, water lysis, direct inoculation and addition of centrifuged pellet into brain-heart infusion broth and by automated blood culture system. Identification and antibiotic susceptibility of organisms was done, and the outcome of PD-related peritonitis was analysed. Statistical Analysis Used: The categorical data and continuous data were analysed using the Chi-square test and Student's t-test, respectively. P < 0.05 was considered statistically significant. Results: Of the 100 PD fluids, 87 were culture positive. Automated blood culture systems detected 87 episodes, whereas conventional centrifuge method detected only 53 episodes (P = 0.00001). Peritonitis due to Gram-negative organisms (62.3%) was higher than that of Gram-positive peritonitis (31.1%) and fungi (6.4%). Nineteen per cent episodes were constituted by relapse (9), refractory (4), recurrent (4) and repeat (2) peritonitis. Outcomes were analysed as recovery (77%), catheter removal (15%) and death (2.6%). Conclusions: Direct inoculation of peritoneal fluid into automated blood culture bottles increases the positivity rate and also aids in the early detection of CAPD peritonitis, helping reduce morbidity and mortality of PD patients.

Incidence, Microbiological Profile, and Impact of Preventive Measures on Central Line-associated Bloodstream Infection in Liver Care Intensive Care Unit.

AIMS AND OBJECTIVES: Central line-associated bloodstream infection (CLABSI) is among one of the preventable healthcare-associated infections (HAIs). The data for the CLABSI rate in liver care intensive care unit (LCICU) patients are scarce, so the present study was conducted to ascertain the CLABSI rate, the microbiological profile, and the impact of preventive measures for reduction of infection. MATERIALS AND METHODS: This is a prospective observational study done on LCICU patients during the period of January 2017-December 2018. We followed up patients on the central venous catheter for the development of CLABSI as a part of routine surveillance of HAIs. The impact of introduction and implementation of the CLABSI bundle to reduce the CLABSI rate was analyzed and the microbiological profile of infection was determined. RESULTS: During the study period, the total number of patients admitted in LCICU were 1,336 (648 in 2017 and 688 in 2018) and a total of 995 central lines were inserted for various indications. A total of 57 patients were meeting the CLABSI criteria among 7,324 central line catheter days of surveillance. In year 2017, rate of CLABSI was 11.78/1,000 catheter days and after implementation of the bundle in 2018 the rate reduced to 3.99/1,000 catheter days. Gram-negative organisms (86%) predominated with Pseudomonas aeruginosa being the most common pathogen (19.3%). Out of 49 isolates of gram-negative bacilli (GNB), 40 (81.6%) were multidrug resistant (MDR) and 9 (18.4%) were pan-drug resistant. CONCLUSION: We found significant reduction in the CLABSI rate after implementation of the bundle of care. Gram-negative bacilli were the most common pathogen in our study and antimicrobial resistance was very high, which suggest hospital environment as a source of infection. CLINICAL SIGNIFICANCE: Knowledge of the microbiological profile and the preventive strategy of CLABSI is essential for prevention and timely initiation of the most appropriate anti-infective therapy, if it happens.
