Between 1966 and 1976, overall surgical rates in Canada remained relatively unchanged and consistently 60% higher than those in England and Wales. Overall United States rates were the highest of the three countries and increased 25% over the ten years. Numbers of surgeons per capita increased in both Canada and England and Wales but overall surgical rates in the two operative rates increased. During the decade, Canada had more hospital beds per capita than the United States while England and Wales had the fewest. Since 1970, the percentage of gross national product spent on health care has been greatest in the United States, intermediate in Canada, and lowest in England and Wales. These expenditures may better reflect national priorities and value and, thus be more important than per capita numbers of hospital beds or surgeons in explaining the cross-national difference in rates of surgery.
1966年至1976年间,加拿大的总体手术率相对保持不变,始终比英格兰和威尔士高60%。美国的总体手术率在这三个国家中最高,在十年间增长了25%。加拿大和英格兰及威尔士的人均外科医生数量都有所增加,但两国的手术率总体上都有所上升。在这十年间,加拿大的人均医院病床数比美国多,而英格兰和威尔士的最少。自1970年以来,美国在医疗保健方面支出占国民生产总值的百分比最高,加拿大居中,英格兰和威尔士最低。这些支出可能更能反映国家的优先事项和价值,因此在解释各国手术率差异方面可能比人均医院病床数或外科医生数量更重要。
