A comparative study of the costliness of Manitoba hospitals.
OBJECTIVE
In light of ongoing discussions about health care policy, this study offered a method of calculating costs at Manitoba hospitals that compared relative costliness of inpatient care provided in each hospital.


METHODS
This methodology also allowed comparisons across types of hospitals-teaching, community, major rural, intermediate and small rural, as well as northern isolated facilities.


METHODS
Data used in this project include basic hospital information, both financial and statistical, for each of the Manitoba hospitals, hospital charge information by case from the State of Maryland, and hospital discharge abstract information for Manitoba. The data from Maryland were used to create relative cost weights (RCWs) for refined diagnostic related groups (RDRGs) and were subsequently adjusted for Manitoba length of stay. These case weights were then applied to cases in Manitoba hospitals, and several other adjustments were made for nontypical cases. This case mix system allows cost comparisons across hospitals.


RESULTS
In general, hospital case mix costing demonstrated variability in hospital costliness, not only across types of hospitals but also within hospitals of the same type and size.


CONCLUSIONS
Costs at the teaching hospitals were found to be considerably higher than the average, even after accounting for acuity and case mix.
