The patient history file of a medical care insurance plan can be used for statistical purposes in many ways. This is illustrated by the use of the records of the Saskatchewan Medical Care Insurance Commission to study the survival of patients receiving kidney transplants in the period 1970--74. During this period 48 males and 23 females received at least one renal transplant; these patients represented 34% of all males and 28% of all females undergoing regular renal dialysis. These period prevalence estimates are consistent with calculations based on incidence and point prevalence reported elsewhere. Life-table calculations showed the 4-year survival rate following first kidney transplantation in Saskatchewan to be 45% for all patients, 55% for those less than 45 years of age and 26% for those 45 years of age or older.
医疗保险计划的患者病史档案可在很多方面用于统计目的。萨斯喀彻温省医疗保险委员会的记录被用于研究1970年至1974年期间接受肾移植患者的存活率，这说明了这一点。在此期间，48名男性和23名女性接受了至少一次肾移植；这些患者分别占所有接受常规肾透析男性的34%和所有接受常规肾透析女性的28%。这些期间患病率估计值与基于其他地方报告的发病率和点患病率的计算结果一致。生命表计算显示，萨斯喀彻温省所有患者首次肾移植后的4年生存率为45%，45岁以下患者为55%，45岁及以上患者为26%。
