Cost of acute stroke care at a tertiary care hospital in Karachi, Pakistan.

OBJECTIVE: To evaluate cost of acute stroke care and its determinants at a tertiary care hospital in Karachi and to find out predictors of high cost care. Acute stroke is a leading cause of morbidity and mortality. Cost of care is the single most important determinant in availability of acute stroke care at a tertiary care hospital in Pakistan. It is also an important factor in development of public health policies and medical insurance plans. Average annual income in Pakistan is 4881 rupees (85 U dollars).

METHODS: Medical and billing records of 443 patients with acute stroke were retrospectively reviewed from 1998-2001 at The Aga Khan University Hospital (AKUH), Karachi. Acute stroke care at AKUH usually includes routine laboratory investigation including Lipid profile, Magnetic resonance imaging/angiography (MRI/MRA), Echocardiogram, Carotid Doppler's ultrasound and medical management in the Stroke care unit.

RESULTS: 443 patients were included in study. Age range was 25-98 years (Mean 58 years). 269 (61%) were male. Length of hospital stay was 1 day; 67 patients, 2 days; 83 patients, 3 days; 70 patients, 4-5 days; 87 patients, 6-10 days; 75 patients, 11-30 days; 49 patients and more than 30 days; 12 patients. Average length of stay was five days and median length was three days. Average total cost was 70,714 rupees (1179 U dollars) which included average radiology cost; 12,507 rupees (208 U dollars), average laboratory cost; 8365 rupees (139 U dollars), average pharmacy cost; 13,320 rupees (222 U dollars) and average bed/room charges; 27,552 rupees (459 U dollars). Length of hospital stay is the most important determinant of cost. Average total cost for patients who stayed for 1 day was 19,597 rupees (326 U dollars), 2-3 days; 25,568 rupees (426 U dollars), 4-7 days; 49,705 rupees (828 U dollars), 8-30 days; 153,586 rupees (2559 U dollars), more than 30 days; 588,239 rupees (9804 U dollars). Average cost for general ward was 60,574 rupees (1010 U dollars), private ward was 74,880 rupees (1248 U dollars) and intensive care unit was 155,010 rupees (2583 U dollars).
