Incidence and root causes of surgery cancellations at an academic medical center in Iran: a retrospective cohort study on 29,978 elective surgical cases

Abstract

Abstract Introduction Canceling scheduled surgeries on the day of surgery places a heavy burden on healthcare providers and has psychological, social, and financial consequences on patients and their families. This study aimed to investigate the main reasons for cancellations of elective procedures and provide appropriate recommendations to reduce the rate of such avoidable cancellations. Methods Data were collected retrospectively from all consecutive elective cases scheduled for various elective surgeries from January 1, 2020 to March 31, 2022 at Namazi Teaching Hospital, a major referral center in southern Iran with a capacity of 938 beds. Daily data were collected on the number of planned electives, cancellations, and reasons for cancellations. Surgical cancellation reasons were categorized as patient-related, surgeon-related, hospital/system-related, and anesthesia-related. Data were expressed as frequency (percentage) and analyzed with SPSS version 19 software. Results The cancellation rate on surgery day for elective procedures in all fields was 6.3%. The highest cancellation rate was related to minor surgeries (19%), followed by urology (8%), pediatrics (7%), and plastic surgery (7%). The most common reasons for cancellation were patients not suitable for the procedure (37%), followed by patients who did not follow instructions (10%), lack of time (10.5%), and equipment/supplies problems (10%), and refusal to consent (6%). Conclusions According to this study, patients’ unsuitability for surgery, non-compliance with instructions, lack of time, and problems with equipment/supplies are the main reasons for canceling surgery. Proper preoperative assessment and preparation of patients and improved communication between medical teams and patients reduce the cancellation of booked surgeries.
