(Tuesday, May 17, HealthDay News) - obese patients at significantly increased risk for surgical infections after suffering a partial ablation or full colon, a new study concludes.
It consisted of 7,020 patients, aged 18 to 64 years who had a partial or total colectomy for cancer of the colon, diverticulitis or a inflammatory bowel disease between 2002 and 2008. Of these patients, 1 243 were obese.
The overall rate of infection of surgical was 10.3%, but the rate was higher in obese patients (14.5%) than non-obese patients (9.5%). After adjustment for a certain number of factors, the researchers calculated that obese patients were more likely to develop infections of surgical and non-obese patients of 60 per cent.
The average cost of colectomy for all patients was $ 16,399, but the average price of obese patients was approximately $295 for non-obese patients.
The researchers also found that surgical infections significantly increased the cost of the procedure. The average total cost for patients who have developed surgical infections was $31,933, compared to $14,608 for patients without infection.
Patients with surgical infections were also more average hospitalizations (9.5 days against 8.1 days) and a higher rate of readmission (27.8% vs. 6.8%) of the hospital.
"We conclude that patients undergoing colorectal surgery who develop SSIs [surgical infections], many of whom are obese, taxing the health care system,", wrote Dr. Elizabeth c. Wick, the Johns Hopkins School of Medicine in Baltimore and his colleagues.
Of the programmes of measures incentives Surgeons of reward for costs and improving outcomes for patients must take into account that obese people are more at risk of infection, according to the authors.
The study appears in the may issue of Archives of surgery.
