RISK FACTORS FOR WOUND INFECTION; A CASE CONTROL STUDY

Dr. Abdul Wasay, Dr. Afshan Fayyaz, Dr. Usbah Khalid

Abstract: Wound infections lead to prolonged hospital stay and increase treatment cost and treatment burden on in hospital settings. The mortality and morbidity rate increases. The risk factors responsible for wound infections are needed to be studied so that timely control can reduce the drastic outcome. A case control study was conducted on patients with colorectal surgery, they were admitted in postoperative ward on surgical floor. Two groups of patients were selected. One was labeled as case group; those who already had infected wound following colorectal surgery and other control group which included colorectal patients with healthy wounds. There were 57 patients in case group, 57% underwent emergency surgery while elective surgery whether in the form of laparoscopy or open was performed on 88%, laparoscopy was later converted to open surgery in a few patients depending upon their surgical complications. High ASA grade was present in 40% patients. Obesity and open surgery was more commonly associated with wound infection. Duration of hospital admission following surgery was twice longer in patients with infected wounds than that of healthy wounds. Increasing rate of laparoscopic surgeries and adopting modified wound care protocols for obese patients can help reduce the post-operative wound infections in colorectal patients and will result in lowering risk for long term morbidity and will reduce mortality and treatment cost. Keywords: Colorectal surgery, laparoscopy, wound, infections, obesity, open surgery, treatment, factors.
