The Department of Family Medicine and Practice at the University of Wisconsin-Madison has devised and implemented an alpha-numeric system of identifying patient records together with a system of chart filing based on a variation of terminal digit filing. The system provides each patient with a unique identification number. This permanently assigned number is used as part of the medical record (chart) information, as the basis for assigning an account number, as the basis for determining the storage location of the chart in the record room, and as the basis for a family identification number. The number defines the patient's sex and position within the family, and its permanency ensures a capability for conducting both short- and long-term ambulatory care research in the family context.
威斯康星大学麦迪逊分校的家庭医学与实践系设计并实施了一种用于识别患者记录的字母数字系统，以及一种基于末位数字归档变体的图表归档系统。该系统为每位患者提供一个唯一的识别号码。这个永久分配的号码用作病历（图表）信息的一部分，用作分配账号的依据，用作确定图表在档案室存储位置的依据，以及用作家庭识别号码的依据。该号码定义了患者的性别和在家庭中的位置，其永久性确保了在家庭环境中进行短期和长期门诊护理研究的能力。
