INTRODUCTIONThe cost of health care delivery is increasing everyday. Hence there is need for healthcare teams to encourage cost effectiveness in every aspect of patient care. It also leads to prolonged hospital stay and in many cases repetition of various aspects of pre-operative preparation. Apart from economic loss to hospital, it is also stressful for patients and their families. All of these increase patients therapeutic expense. Avoidance of cancellation of elective surgery, therefore should lead to reduction in the overall cost of treatment.In UK 8% of scheduled elective operations are cancelled nationally, within 24 hours of surgery.1 In total 10 to 40% of booked elective operations are cancelled before the surgery takes place. The reasons include cancellation by the patient, cancellation for poorly optimized medical conditions or cancellations due to poor organization, lack of co-ordination among the surgical team and the anaesthetist, or sometimes poor co-ordination between the patient and the hospital administration.2 A variety of studies have examined the reasons for late cancellations based on the retrospective analysis of hospital records. [3][4][5][6][7][8][9][10][11][12] This audit was a retrospective study in a medical teaching hospital. The aim was to assess the causes of cancellation of orthopedic procedures scheduled on day of surgery and ABSTRACT Background: A retrospective observational study was conducted to find out the reasons for cancellation of elective orthopedic surgical inpatients on the day of surgery and to plan for future suggestive actions to decrease unnecessary cancellations. Methods: This was a retrospective observational study conducted at medical teaching hospital for 3 years from January 1, 2012 to December 31, 2014. The data was collected from postponement register. The files of cases that were cancelled were reviewed for the reasons of cancellations. The reasons were classified as anaesthetist related, administrative issues, surgeon related and patient related issues. Results: During the study period, 7673patients were posted for elective orthopedic procedures. 6.49 % patients were cancelled on the day of surgery. The frequency of cancellations was more in anesthetist related issues (38.9%). Cancellations due to administrative issues, patient related issues and surgeon related were 30%, 27.7% & 3.4% respectively. Conclusions: Although cancellations were only 6.49% of total elective operations, this can be reduced by implementing and following the recommendations that have been proposed. More thorough and detailed documentation is needed to achieve this.
