A knowledge of the extent and distribution of chronic comorbidity plays an essential role in providing appropriate care, and allocating health resources to the patients admitted to the emergency department. We performed a cross-sectional study to quantify the chronic diseases presenting in the Emergency Department of PGIMER, Chandigarh (India). Out of 205 patients, 133 (64.9%) had pre-existing comorbidity. Common were chronic kidney disease (29, 14.1%), chronic liver disease (23, 11.2%), diabetes mellitus (21, 10.2%), malignancy (20, 9.8%), cardiac diseases (17, 8.3%), and chronic obstructive pulmonary disease (9, 4.4%). The median Charlson comorbidity index score was 2 (range, 0–9). In-hospital mortality was 43 (21%) and was predicted by older age (median, 60 v. 50 years; p-value, 0.017). Deaths with previous stroke (66.6%), chronic obstructive pulmonary disease (55.6%), and diabetes (28.6%) were higher than cardiac (2.3%) and renal (6.9%) comorbidity. Increasing comorbidity requires a shift in existing models of emergency care.
