Alternatively, the model could be fitted using the generalized estimation equations [37]. 4 Intermediate events In prospective studies, information is often available on intermediate events that patients may experience between registration and admission to hospital for treatment. These include delay in scheduling the operation, 16 1 Health services research on access to care cancellation of booked services, reinstatement following medical deferral, and failure to attend. The occurrence of the events preceding admission may alter the admission rate in one group and have no effect in the other, have the same effect in both groups, or have different effects in each group.

1) For example, the estimated proportion of patients who were admitted for surgery during week i from the time of their registration on a wait list is estimated as pˆi = ei . 2) In this example, the event is surgery during week i, and the patients at risk are those who were still on the wait list at the beginning of that week. Another example is the proportion of patients who underwent surgery within the TAT, which is estimated by pˆ = 1 n0 ei . 3) {i|ti ≤TAT} Here, the event of interest is surgery within the TAT from registration, and the patients at risk are all those accepted on a wait list.

Conversely, scheduled surgery may be moved ahead if an operating room time slot becomes available. On the day of a scheduled procedure, the anesthesiologist and the attending surgeon assess the patient before transfer to the operating room holding area. After the operation, the patient is taken to the postanesthesia care unit for monitoring and treatment of possible side effects of anesthesia. The anesthesiologist performs a postsurgical assessment, and the patient is transferred to the intensive care unit or to a hospital ward for further treatment [14].
