From January 1 to July 31, 1989, there were 774 operations performed and qualified for this prospective study. The various factors that may affect the development of surgical wound infection were presented and those found significant are:(1) Degree of contamination - the operation type specific surgical wound infection rate are higher than acceptable which include even clean operation at 2.5%.(2) The infection rate for consultants and residents as operators were comparable.(3) Surgical wound infection rates were found to be higher in the following settings: prolonged operations, emergency procedures, secondary wound closure, shaving the operative site more than 2 hours before surgery, overindulgence in combination hemostatic control (suture ligation and electrocautery) and use of cat gut in subcutaneous layer and presence of complicating conditions such as sepsis and malnutrition. Knowing these different variables in the development of surgical wound infection, carefulness in handling a surgical patient not only in terms of expertise in extirpating the deceased organ but more importantly in the proper handling of surgical wounds should be developed.

The study aimed to: (1) determine the surgical wound infection (SWI) rate among performed operations in the department of surgery and (2) determine the various factors contributory to the development of this wound infection.
