Purpose
To analyze the impact of postoperative remote infections (PRIs) on medical expenditure.
Methods
The subjects of this retrospective study were 338 patients who had undergone gastroenterological surgery at one of the 20 Japanese institutions within the Japan Society for Surgical Infection (JSSI) and mainly authorized as educational institutions. The patients were allocated to 169 pairs of those with a PRI (PRI (+) group) matched with those without a PRI (PRI (−) group). PRIs included pneumonia, urinary tract infection (UTI), catheter-associated blood stream infection (CA-BSI), and antibiotic-associated enteritis.
Results
SSI developed in 74 of the 338 patients (22 without PRI and 52 with PRI). The SSI incidence was significantly higher in the PRI (+) group (p < 0.001). The difference in the median postoperative length of hospital stay was 15 days, indicating a significant prolongation in the PRI (+) group (p < 0.001). The PRI (+) group also had a higher rate of inter-hospital transfer (p < 0.01) and mortality (p < 0.001). Similarly, the difference in median postoperative medical fees was $6832.3, representing a significant increase in the PRI (+) group (p < 0.001).
Conclusions
The postoperative length of hospital stay is longer and the postoperative medical expenditure is higher for patients with a PRI than for those without a PRI.
