DIRECT COSTS


OTHER COSTS


Other health care system costs have not been studied in Canada (such as, laboratory tests and procedures, non-physician professional services, home care, long-term care). They have not been well studied, if at all, in other countries. Often, they are reported without enough detail in order to accurately convert data to a current Canadian cost. As mentioned earlier, patterns of care in other countries are not necessarily the same as in Canada. However, international studies are needed to get an estimate of these other costs, because there are no Canadian sources. In this situation, it is important to be as conservative as possible – that is, to underestimate the costs wherever there is uncertainty in the results. We can piece together estimates from other countries where they do not overlap with any other resources. This procedure may end up missing some costs, but it is conservative estimate.

Canada was estimated based on the cost in the US or in Australia, to reflect the size of the Canadian IBD population. A total of $101 million in additional health care system costs is estimated for IBD in Canada, corresponding to $433 per person per year.


TOTAL DIRECT COSTS


Total direct costs top $1.2 billion, and are shown in Figure 1. They are not broken down into CD versus UC because the prescription drug costs could not be reliably and accurately separated by disease. Drug costs were the single largest component of cost, followed by inpatient hospitalization. Together these two items constituted 76% of the direct medical costs of IBD.
