Hospital discharge rates vary substantially among 60 communities in Michigan. (R2 = 90 percent and R2 = 85 percent of the systematic variance is explained by community effects for nonsurgical and surgical discharges, respectively.) The ranking of communities by discharge rates is stable over a five-year period (Spearman rho = 0.78 for nonsurgical discharges and 0.72 for surgical discharges). Surgical discharge rates decreased substantially (4 percent per year) over this time period, while nonsurgical rates showed no consistent pattern. Communities with exceptional discharge rates showed no substantial or significant regression toward the mean through the five-year study.
密歇根州60个社区的医院出院率差异很大。（对于非手术和手术出院情况，社区效应分别解释了系统方差的90%和85%。）出院率的社区排名在五年期间保持稳定（非手术出院情况的斯皮尔曼等级相关系数为0.78，手术出院情况为0.72）。在此期间，手术出院率大幅下降（每年4%），而非手术出院率则没有一致的模式。在为期五年的研究中，出院率异常的社区没有出现向均值的大幅或显著回归。
