How will the colonoscopy base volumes at each hospital be measured for 2006/07?
Current base volumes for colonoscopies are based on the 2005/06 physician billing data (OHIP) and the rate of growth of colonoscopies since 1997/98. The OHIP data were supplemented with data from NACRS to identify the hospitals where the services were provided. Unfortunately, the NACRS diagnostic and procedure codes and practices do not definitively identify a colonoscopy, but this is being addressed for 2007/08 to make them more identifiable. We recognize that hospitals do not have access to OHIP data. CCO has a query for the MOHLTC Provincial Health Planning Database that allows LHINs to count colonoscopies using the OHIP-NACRS linkage approach. The program can share this with LHINs as requested.
