چکیده

length of hospital stay (los) is a key indicator for hospital management. reducing hospital stay is a priority for all health systems. we aimed to determine the length of hospital stay following coronary artery bypass surgery (cabg) based on its clinical and non-clinical factors. a cross-sectional study of 649 consecutive patients who underwent coronary artery bypass graft surgery was conducted in imam khomeini and shariati university hospitals, tehran, iran. data was analyzed by using non-parametric univariate tests and multiple linier regression models. thirty seven independent variables including pre-operative, intra-operative and post-operative variables were analyzed. finally, an appropriate model was constructed based on the associated factors. the results showed that 70.3% of the patients were male, and the mean age of the patients was 59.3 ± 10.4 years. the mean (±sd) and median of the los were 11.7 ± 7.1 and 9 days, respectively. of 37 investigated variables, 24 qualitative and quantitative variables were significantly associated with length of stay (p<0.05). multiple linear regression analysis showed that independent variables including age, medical insurance type, body mass index, and prior myocardial infarction; admission day, admission season, cross-clamp time, pump usage, admission type, the number of laboratory tests and the number of specialty consultation had more effect on the hospital stay. we concluded that some significant factors influencing hospital stay after cabg were predictable and modifiable by hospital managers and decision makers to manage hospital beds. |
