Factors affecting Mortality in Neurosurgical ICU of Manipal Teaching Hospital, Pokhara, Nepal

Abstract

Introduction: Mortality is an important self-assessment tool in medical practice. This study assesses various factors associated with mortality in Neurosurgery ICU (NS-ICU).

Methods: A prospective, cross-sectional study was carried out from January 2017 to December 2017 in 416 patients admitted to NS-ICU. The age, sex, diagnosis, GCS, pupil’s abnormality, vital parameters, laboratory parameters, comorbidities were compared in between mortality and survival group. The individual component of GCS was further evaluated.

Results: Out of 416 patients, 374 (89.90%) patients were in survival group and 42 (10.10%) patients in mortality group. Trauma 188(45.20%) and Cerebrovascular accident 133(31.97%) were commonest diagnosis on admission. The GCS, eye-opening and motor component of GCS, abnormal pupils, hypertension (HTN), diabetes mellitus (DM), diastolic blood pressure (DBP), heart rate (HR), operated cases and serum urea levels were found to have significant difference between mortality and survival group. These parameters were further subjected to binary logistic regression which showed DBP (B-0.01, p=0.00), HR (B0.02, p=0.00), motor score of GCS (B-0.50, p=0.04), operated cases (B 1.13,p=0.00), abnormal pupils (B1.85,p=0.00), DM (B1.56, p=0.00) to have significant association with mortality.

Conclusions: High heart rate, low diastolic BP, low motor score of Glasgow Coma Scale, abnormal pupils, diabetes mellitus and operated cases were found to be significantly associated with mortality.
