Mortality Profile of Critical Patients in Medical Intensive Care Unit of Government Medical College of Central India

Abstract

Introduction: Mortality rate is always very high in Intensive Care Units (ICU) even with the best possible set ups, we should try to cater the need of the society according to the disease burden so that better care can be provided. Aim: To estimate the prevalence of various medical disease mortality profile of critically ill patients admitted in Medical Intensive Care Unit (MICU) of our institution. Materials and Methods: This was a retrospective observational study done at MICU of Bundelkhand Medical College and Hospital Sagar, Madhya Pradesh, India for a duration of one year (1st January 2019 to 31st December 2019). Data was retrieved from Medical Records Department (MRD) and total data of 349 deaths were registered. Disease was classified based upon ICD 10 (International Statistical classification of Diseases and related health problems) Score. Results: A total of 349 deaths occurred in MICU during the period of one year at the institution, out of which male deaths were 55.9% and Female deaths were 44.1%. MICU deaths occurred in higher numbers in males with Male: Female ratio of 1.2:1. This difference in ratio of male and female mortality was not statistically significant (p-value >0.05). Mean age of males at time of death was 58.4±16.3 years whereas mean age of females were 55.2±19.7 years. This difference in mortality with age and gender was not statistically significant (p-value >0.05). In present study, most common systemic causes of mortality were cardiovascular (29.8%), followed by respiratory (17.5%), renal (16.5%) and cerebrovascular diseases (13.8%). Mortality was documented in 276 (79%) individuals within duration of seven days of admission, whereas mortality in 46 (13.1%) and 27 (7.7%) cases were documented within 8 to 14 days and >14 days, respectively. The present study documented no statistically significant association between length of stay and age of patients (p-value >0.05). Conclusion: Cardiovascular diseases are the most common causes leading to mortality especially in elderly male patients. Also, higher number of deaths is reported within seven days of admission signifying severity of illness at the time of admission.
