Temporal patterns in the use of health services leading to cholecystectomy: a process evaluation using insurance records.
Data from Saskatchewan's public medical and hospital insurance programs are used to estimate a multivariate model of health services utilization among cholecystectomy patients. A methodology is developed which partitions the care process into an assessment period, a waiting period, and a hospitalization period. The general hypothesis is that presurgical and surgical decisions of physicians are influenced by extra-medical factors, including the social condition of the patient and the availability of health resources. This hypothesis is only weakly supported by the data.
