Hospitalization tables of the U.S. Renal Data System allow description of national hospitalization rates among incident and prevalent dialysis patients in five-year age groups. These rates are further stratified by sex, race, and four primary disease categories. Based on these tables derived from the data on over 250,000 incident and prevalent patients during 1991 to 1993, a methodology is described that allows comparison of local (for example, dialysis facility) or regional "first admission" rates among incident and prevalent dialysis patients to the national rates. A standardized hospitalization ratio is introduced to facilitate such comparisons, and methods for assessing statistical significance are discussed. Since this methodology allows adjustment for age, race, sex, and primary disease, it can serve as useful tool for dialysis research. It can also be used at the dialysis facility level, alone or in conjunction with the standardized mortality ratio, to facilitate local quality assurance.
美国肾脏数据系统的住院表格能够描述按五岁年龄组划分的新发病例和长期透析患者的全国住院率。这些比率进一步按性别、种族和四种主要疾病类别进行分层。基于1991年至1993年期间超过250,000例新发病例和长期透析患者的数据得出的这些表格，本文描述了一种方法，该方法可以将新发病例和长期透析患者的本地（例如透析机构）或区域“首次入院”率与全国率进行比较。引入了标准化住院率以促进此类比较，并讨论了评估统计学显著性的方法。由于该方法能够对年龄、种族、性别和主要疾病进行调整，它可作为透析研究的有用工具。它也可单独或与标准化死亡率一起用于透析机构层面，以促进本地质量保证。
