RESUMO
Background: Carbapenem-resistant Enterobacteriaceae, especially Klebsiella pneumonia, have become a severe global problem with a significant threat to public health, but few studies have investigated the risk factors and epidemiology of carbapenem-resistant K. pneumonia (CRKP) infections in India. Methods: We performed a retrospective observational study of 224 participants with K. pneumoniae who were admitted to the medical intensive care unit (ICU) of Institute of Medical Sciences and SUM Hospital, Bhubaneswar, India, between January 1 and December 30, 2020. Antibiotic susceptibility testing was done by automated broth microdilution VITEK® 2 (BioMerieux, Inc., Hazelwood, USA). The Clinical and Laboratory Standards Institute document M100-S22 (January 2020) was used to interpret antimicrobial susceptibility testing. Data were obtained from paper medical records. Results: Two hundred and twenty-four subjects with culture-positive for K. pneumonia were retrieved during the study period, out of which 108 had CRKP. The risk factors for univariate analysis were Acute Physiology and Chronic Health Evaluation II, ICU length of stay (LOS), invasive mechanical ventilator days, central venous catheter days, and arterial line days. The multivariate analysis showed invasive mechanical ventilation and ICU LOS were independent risk factors for CRKP infection. Mortality in the CRKP group was 48 (44%) compared to 27 (23%) in the carbapenem-sensitive K. pneumonia (CSKP) group, which was statistically significant (P < 0.01). Conclusion: Infection due to CRKP in the ICU was associated with 1.9 times higher mortality as compared to CSKP. Invasive mechanical ventilation and ICU LOS were found to be independent risk factors for CRKP infection.
RESUMO
BACKGROUND AND AIMS: Simulation is one of the important learning tools when it comes to skill acquisition and as a supplemental tool for training in high stake situations like COVID-19. The aim of this study is to meet the global requirements of knowledge on ventilatory management, prepare and to evaluate the effectiveness of the teaching module for non-anesthesiology trainees on COVID-19 patients. METHODS: Quasi experimental cross sectional pilot study was conducted with a sample of twenty-six trainees. A teaching module was prepared and validated which consisted of lectures, audio-video sessions, demonstrations with hands-on training, debriefing, analytical-phase and reflection. Pre and Post evaluations from student t-test and direct observation of procedural skills (DOPS) were used for knowledge and skill assessment respectively and feedback obtained from Likert's score. RESULTS: Pre- and Post-tests had a mean score of 7.42 ± 2.12 and 14.92 ± 2.9 respectively (P value 0.00001). DOPS included 16 point score, in which 23 trainees (88.4%) met the expectations and above expectations as per training objectives. A five-point Likert's score feedback revealed satisfactory and highly satisfactory scores of 100% (ABG), 96.1% (mechanical ventilation), and 84.6% (ventilation in COVID-19 patients). Overall satisfaction for the workshop among respondents was 100 per cent. Confidences of handling scores were 84.5% (interpreting ABG), 65.3% (maneuvering mechanical ventilation), and 96.15% (intubation in COVID-19 patients). CONCLUSION: A planned teaching module in ventilation management helps to train non-anaesthesiologists more effectively as a part of COVID-19 preparedness. Simulation with debriefing based training to the medical fraternity is the best alternative in the present pandemic and it will also ensure the safety of health care professionals.
