Good quality data are required to plan and evaluate diabetes services and to assess progress against targets for reducing hospital admissions and bed days. The aim of this study was to assess the completeness of recording of diabetes in hospital admissions using recent national data for Scotland.
Data derived from linkage of the Scottish National Diabetes Register and hospital admissions data were analysed to assess the completeness of coding of diabetes in hospital inpatient admissions between 2000 and 2007 for patients identified with diabetes prior to hospital admission.
In 2007, only 59% of hospital inpatient admissions for people previously diagnosed with diabetes mentioned diabetes, whereas over 99% of people with a mention of diabetes on hospital records were included in the diabetes register. The completeness of diabetes recording varied from 44 to 82% among mainland National Health Service Boards and from 34 to 89% among large general hospitals. Completeness of recording of diabetes as a co-morbidity also varied by primary diagnosis: 70 and 41% of admissions with coronary heart disease and cancer as the primary diagnosis mentioned co-existing diabetes, respectively.
There is wide variation in the completeness of recording of diabetes in hospital admission data. Hospital data alone considerably underestimate the number of admissions and bed days but overestimate length of stay for people with diabetes. Linkage of diabetes register data to hospital admissions data provides a more accurate source for measuring hospital admissions among people diagnosed with diabetes than hospital admissions data.
需要高质量的数据来规划和评估糖尿病服务，并评估在减少住院人数和住院天数方面的目标进展情况。本研究旨在利用苏格兰最近的全国数据评估 2000 年至 2007 年期间，在住院前确诊为糖尿病的患者的住院记录中糖尿病记录的完整性。
通过链接苏格兰国家糖尿病登记处和住院数据，对数据进行了分析，以评估 2007 年之前诊断为糖尿病的患者的住院记录中糖尿病编码的完整性。
在 2007 年，仅有 59%的住院患者在住院前被诊断为糖尿病时提到了糖尿病，而在住院记录中提到糖尿病的人中，超过 99%都被纳入了糖尿病登记处。在国民医疗服务体系内地各委员会中，糖尿病记录的完整性从 44%到 82%不等，在大型综合医院中从 34%到 89%不等。作为合并症的糖尿病记录的完整性也因主要诊断而异：分别有 70%和 41%的冠心病和癌症住院患者提到了并存的糖尿病。
在住院患者数据中，糖尿病记录的完整性存在广泛差异。仅医院数据会大大低估糖尿病患者的住院人数和住院天数，但会高估其住院时间。将糖尿病登记处数据与住院数据进行链接，为衡量已确诊糖尿病患者的住院人数提供了比住院数据更准确的来源。
