Utilization of hospital services by cardiovascular patients, Alberta, Canada.

Using hospital discharge records, and United States DRG (diagnosis related groups) data, we studied hospital utilization by cardiovascular patients, associated hospital expenditures, and the per capita cost of treating cardiovascular diseases in Alberta, Canada between 1971 and 1986. Expressed in constant 1984 Canadian dollars, the estimated total hospital cost increased from $84 million in 1971 to $131 million in 1986; during this period the Province of Alberta spent about $51 Canadian per resident each year for cardiovascular hospital services. It was noted that rural residents consumed a higher volume of resources per capita than their urban counterparts. A patient origin-destination analysis indicated an increasing dependence of rural patients on urban hospitals for secondary or tertiary care, underscoring the effects of medical technology on referral patterns.
