Awake Prone Positioning In COVID Positive Patients: A Retrospective Study.

BACKGROUND: While the advanced health care settings are struggling hard to handle the sudden surge of COVID-19 cases, resource poor settings in developing countries like Nepal can barely stand to fight the increasing number of severe cases. Easily available cost effective interventions would be great blessing for such settings. This study aimed to study if awake prone positioning can be used as such intervention in COVID 19. METHODS: The retrospective study involved 150 patients admitted between November 2020 and January 2021 at Nepal Armed Police Force Hospital and met specific inclusion criteria. Data was obtained at four different time points in relation to prone position and was analysed using International Business Machines Statistical Package for the Social Sciences (SPSS) version 23. RESULTS: It was found that among 150 patients, majority (109; 72.7%) were males and 60(40%) had some comorbidities. The mean oxygen saturation was found to increase significantly from 87.18 %(SD 3.531) to 91.08(SD 2.206) after fifteen minutes of prone positioning. One way ANOVA test showed that there was significant difference in oxygen saturation between at least two time points. (F (3,596) = [180.005], p=0.000). Games Howell Post Hoc test for multiple comparisons showed that the mean value of SPO-2 was significantly different across all four time points, at significance level 0.05. CONCLUSIONS: This study found Awake Prone positioning as a promising cost effective and feasible intervention for improving oxygenation in COVID 19 and thus could be a blessing to the resource poor health care settings.

Sepsis among Adults Admitted to Intensive Care Unit of a Tertiary Care Centre.

Introduction: Sepsis is a syndrome that starts with an infection, causes organ dysfunction, and leads to death is a global health issue in critically ill patients. While its epidemiology is well-known in high-income countries, it is poorly understood in low- and middle-income countries, including Nepal. This study aimed to find out the prevalence of sepsis among adults admitted to the intensive care unit of a tertiary care centre. Methods: This descriptive cross-sectional study was conducted among adults admitted to the intensive care unit after obtaining ethical approval from the Ethical Review Board. Data was collected from 11 January 2022 and 29 December 2022 from hospital records. A convenience sampling method was used. The point estimate was calculated at a 95% Confidence Interval. Results: Among 195 patients, the prevalence of sepsis was seen in 74 (37.95%) (31.14-44.76, 95% Confidence Interval). Septic patients had a median age of 44 (interquartile range: 33.75±60.25) years. A total of 40 (54.05%) were male. A total of 28 (37.84%) septic patients were identified with ≥2 diagnoses, while 9 (12.16%) had ≥2 comorbidities. Conclusions: The prevalence of sepsis among adult patients admitted to the intensive care unit was higher as compared to other studies done in other international studies. Keywords: intensive care units; prevalence; sepsis.

Antimicrobial Susceptibility Pattern in Opportunistic Pathogens Isolated from Immunocompromised Patients.

BACKGROUND:  Brought with the advancements in transplantation science and the development of immunosuppressive agents, immunocompromised patients characterized with defective immunity have increased throughout the world with increased risk for opportunistic infections. This study provides an overview of the antimicrobial susceptibility pattern among opportunistic pathogens isolated from immunocompromised patients.  Methods: Clinical and laboratory records of immunocompromised patients [patients with chronic kidney disease neutropenia, diabetes, rheumatic heart disease acquired immune deficiency syndrome hepatitis B, hepatitis C, who were subjected to microbiological culture analysis in the Department of Clinical Microbiology, KIST Medical College and Teaching Hospital, for 2 years (January 2019 and December 2020) were analyzed. RESULTS:  Out of 8,402 immunocompromised patients, 954 (11.4%) patients were subjected to microbiological culture analysis. Among 954 patients, 253 (26.5%) patients [median(interquartile range) age: 52(31-67) years; male 138 (54.5%)] were infected. A total of 295 pathogens were isolated from 1,331 cultured samples. Infections due to Escherichia coli (n=71, 24.1%), Klebsiella spp. (n=55, 18.6%), Acinetobacter calcoaceticus-baumannii complex (n=35, 11.9%), Candida albicans (n=30, 10.2%), and Staphylococcus aureus (n=28, 9.5%) were frequently observed. Among the bacterial isolates (n=239), 81.6% (n=195) of bacteria were ß-lactamase producers, 51.0% (n=122) were multi-drug resistant, 9.2% (n=195) were extensively-drug resistant, 0.8% (n=195) were pan-drug resistant, and 35.7% (n=10) of S. aureus were methicillin-resistant Staphylococcus aureus. CONCLUSIONS:  The majority of infection in immunocompromised patients is caused by Gram-negative bacteria, and is often associated with a higher number of ß-lactamase producers and multi-drug resistant organisms. Prescriptions of antibiotics on the grounds of antimicrobial stewardship might help to reduce the burden of antimicrobial resistance.
