Medical center in Northern Taiwan as example
 
The study aims to explore the differences between unplanned return operation and the planned surgery in patient¡¦s 
length of stay in hospital, in intensive care unit (ICU) and died within 30 days after surgery. 

Methods: 


The study adapted retrospective and case match design. Data source was 15,024 hospitalized surgical patients, included 
inpatient surgery and after emergency surgery, from a medical center in northern Taiwan. Experimental group (unplanned 
return) was accordance with the type of surgery by physicians ticked (n=185). Control group (planned surgery) patients 
was matched sequentially according to the experimental patient's surgery department, sex, and age (¡Ó 2 years) (n=352). 
Using STATA11.2 software distributes to the frequency, percentage, the average, standard deviation, chi-square test, t 
test, ANOVA analysis, logistic regression and multiple regression analysis. 

Results: 


Under the control of patient¡¦s anesthesia type, operation duration, wound classifications variables, compared to the 
planned surgery, unplanned return surgery does significantly affect the length of stay in hospital (£]=0.889, p=0.000), stay 
in ICU days (£]=0.628, p=0.001). The occurrence of unplanned return surgery patients died within 30 days after surgery 
was significantly higher than planned surgery does (OR=3.39, P=0.026). 

Conclusion: 


These results confirm the difference in length of stay in hospital, ICU and died within 30 days after surgery of unplanned 
return surgery patients compare to the planned surgery. Unplanned return surgery rates may be useful for monitoring 
quality across hospitals and for identifying opportunities for quality improvement locally.
