Authors' objectives:

To assess the effects of the introduction of extracorporeal shock-wave lithotripsy (ESWL) on the utilization of health care resources (coasts and bed-days) in Quebec.

Authors' results and conclusions: The introduction of ESWL has been associated with a marked reduction in the cost per renal stone patient treated. However, it has not resulted in a reduction of total costs to the Quebec health care system. The main reason why no cost reduction has been realized is that there has been a concomitant, major increase in age-standardized intervention rates (33% for males and 53% for females) and an approximately 59% increase in the number of individuals treated. It is unknown whether this increased rate represents an appropriate new level of intervention due to the availability of a new non-invasive procedure or the treatment of some individuals harbouring asymptomatic stones that would have never become symptomatic. From the point of view of Quebec hospitals, between 1984 and 1992, there has been a shift in bed utilization related to the treatment of urinary calculi from the 65 hospitals without a lithotripter (-7,518 bed-days) to the three hospitals possessing a lithotripter (+1,528 bed-days).
Authors' recomendations: It is suggested that the appropriateness of the additional number of interventions observed in recent years be reviewed by relevant health professionals. It is also important that the shift in resource utilization from one group of hospital to another be recognized by hospital and health care authorities when hospital budgets are reviewed.
