Nigerian surgical outcomes - Report of a 7-day prospective cohort study and external validation of the African surgical outcomes study surgical risk calculator.

Background: Surgical outcomes study for individual nations remains important because of international differences in patterns of surgical disease. We aimed to contribute to data on post-operative complications, critical care admissions and mortality following elective surgery in Nigeria and also validate the African Surgical Outcomes Study (ASOS) surgical risk calculator in our adult patient cohort.

Materials And Methods: We conducted a 7-day, national prospective observational cohort study in consented consecutive patients undergoing elective surgery with a planned overnight hospital stay following elective surgery during a seven-day study period.

Music in the operating theatre: opinions of staff and patients of a Nigerian teaching hospital.

Background: The role of music during surgery has been studied, including its effect on theatre staff, users and patients. However, little attention has been paid to its application especially in our environment.

Methods: It was a prospective study, involving theatre staff, users, and patients.
