[Cost analysis of inguinal hernia surgery in ambulatory and inpatient management].

In Belgium 27,426 hernia repairs were performed in 1994 but only 1,451 (5.29%) were done on ambulatory basis, whereas in the U.S. over 50% of the yearly 600,000 hernia repairs are one day surgery procedures with interstate variation ranging from 6% to 89%. The mean treatment cost of inguinal hernia repair (doctors fees + hotel cost) was 53,704 BEF for inpatients vs. 30,510 BEF (general anesthesia) and 27,501 BEF (local anesthesia) for outpatients. Rates of complication and recurrence were not significantly different. This difference in total costs for hospital admission are determined by the mean length of stay and by the individual forfeitairy day price according to size of the hospital. Also the use of routine diagnostic procedures (clinical chemistry and medical imaging) - not necessarily essential for treatment - is higher at hospitalization. Even with 50% of all hernia repairs carried out in the one day clinic, total cost savings for treatment will hardly exceed 20% if the mean length of stay of the remaining inpatients will not decrease simultaneously. Supplementary and dramatic cost reductions however are possible by an earlier resumption of professional activities. The mean advised sick leave period of 4 weeks (+/- 2) still depends on irrelevant parameters as tradition, patients' preferences, job characteristics and type of insurance. Total costs for work incapacity add up to 2.5 billion BEF (vs. 1.4 billion BEF for total treatment costs) and can be cut by 50.18% via a mean 2 weeks earlier return to work. Since open primary hernia repair under local anesthesia can be easily carried out on outpatients resuming unrestricted daily activities in less than 1 week, the laparoscopic procedure with general anesthesia, higher treatment cost (endoscopic material) and still debated advantages in convalescence time and long-term outcome is not the gold standard for uncomplicated inguinal hernia.
