使用选择算法对1987年南澳卫生规划区的住院分离记录进行了审查，以确定所有涉及腰椎手术（LSS）的腰痛或腿痛住院。在16个卫生规划地区（另外两个地区由于观察数量少而被排除在分析之外）中，LSS率变化几乎是四倍，从25/10万到92/10万，平均值为55/10万。失业率是分析中唯一的重要变量，解释了16个地区手术率变化的11%。这一发现与其他国家的研究一致，这些研究表明，小区域的特征并不能基本预测择期手术的发生率。外科医生及其患者的决策过程仍然定义不清;医疗保健提供系统、医生行为或患者期望对腰椎手术率的贡献尚未确定。
The hospital separation records for 1987 in the health planning regions of South Australia were reviewed using a selection algorithm to identify all hospitalizations involving a lumbar spine surgery (LSS) for low back or leg pain. Among 16 health planning regions (two additional regions were excluded from the analysis because of the low number of observations) the LSS rate varied almost four‐fold, from 25 to 92/100000, with a mean of 55/100000.The effect of 24 socioeconomic and health care supply characteristic variables upon observed differences in rates were tested. The unemployment rate was the only significant variable in the analysis, explaining 11 % of the variation in the surgery rates for the 16 regions. This finding is in agreement with studies from other countries that suggest that characteristics of small areas do not substantially predict the rates of elective surgical procedures. The decision‐making processes of surgeons and their patients remain poorly defined; the contributions to the rate of lumbar spine surgery by the health care delivery system, physician behaviours or patient expectations are not yet identified.
