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.
利用医院出院记录和美国诊断相关组（DRG）数据，我们研究了1971年至1986年间加拿大艾伯塔省心血管疾病患者的医院利用率、相关医院支出以及治疗心血管疾病的人均成本。按1984年不变加拿大元计算，估计医院总费用从1971年的8400万美元增加到1986年的1.31亿美元；在此期间，艾伯塔省每年为每位居民的心血管医院服务花费约51加元。值得注意的是，农村居民人均消耗的资源量高于城市居民。一项患者来源-目的地分析表明，农村患者对城市医院二级或三级护理的依赖程度日益增加，突显了医疗技术对转诊模式的影响。
