Introduction:
Intensive care units (ICUs) play a vital role in managing critically ill patients, but mortality rates remain high, especially in resource-limited settings like Nepal. This study aimed to describe the patterns and clinical characteristics of mortality cases in the ICU of a tertiary care hospital in western Nepal, with specific focus on sex-based differences and their associated comorbidities.
Methods:
A retrospective study was conducted at Lumbini Medical College Teaching Hospital, Nepal, over a one-year period (January 1 to December 31, 2024). This record-based study included mortality data of all ICU patients who died during their hospital stay and had complete medical records. Data on demographics, clinical parameters, comorbidities, laboratory findings, and need for mechanical ventilation were extracted using a structured proforma.
Results:
A total of 82 (21.93%) ICU mortality cases were included out of 374 ICU admissions, consisting of 45 (54.88%) male and 37 (45.12%) female. Median age was 63 (IQR: 46-73) years in males and 70 (IQR: 58-78) years in females. There was clustering of mortality, with 13 (15.85%) deaths occuring in September and 11 (13.41%) in November. The median age of diabetic patients was 72 (IQR: 66-77) years, while the median age of non-diabetic patients was 57.50 (IQR: 44 -73.50) years. The mean systolic blood pressure in diabetic patients was 117.79±22.64 mmHg, and in non-diabetic patients was 102.35±30.20 mmHg.
Conclusions:
The clustering of mortality was seen during a four-month period from August through November. Male patients constituted a majority of ICU deaths due to natural causes.

HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.
