[Costs of appendicitis treatment by diagnosis-related groups in a third-level pediatric hospital].

BACKGROUND

Diagnosis-related groups (DRGs) are widely used in Europe. They allow performing comparisons in hospitals and incurrent hospital payment systems, defining the payment categories. We undertook this study to classify children who underwent appendectomy according to DRGs.

METHODS

Cross-sectional study. Comorbidities, length of hospitalization, histopathologic classification, and DRG classifications were analyzed.

RESULTS

We included 313 patients, 62% males, with an average age of 8 ± 3 years; 91% were referred by another hospital and 67% were treated at night. Average length of hospitalization was 4 ± 3 days. There were comorbidities in 8% and surgical complications in 11%. According to histopathology, appendicitis was edematous (11%), suppurative (36%), gangrenous (22%), perforated (29%), and abscessed (2%). At discharge, 97% of the patients were healthy. Total cost for DRG 343 was $10,470,173.00 (Mexican pesos), DRG 342 was $1,227,592.00 and DRG 340 was $511,521.00. The global amount was $12,209,286.00 (Mexican pesos).

CONCLUSION

The unitary cost for treatment of appendectomy for DRG 343 was $37,935.00, for DRG 342 was $49,103.00 and for DRG 340 was $42,626.00 (Mexican pesos). Because 88% of the cases of appendicitis were uncomplicated, this amount of money could be spent to treat these patients in a second-level hospital, using reimbursement 343 without generating additional expenses.
