目标。制定自我管理的共病问卷（SCQ），并评估其心理测量特性，包括该工具的预测效度，以反映其与1年后健康状况和医疗保健利用的关系。对来自内科和外科护理单位的170名住院患者进行了SCQ与基于图表抽象的标准测量（Charlson指数）的横断面比较。横断面评估SCQ与基于图表的合并症工具和健康状况（简表36）的关联。它们之间的联系。随访1年后，评估患者健康状况及资源利用情况。SCQ与Charlson指数的Spearman相关系数为0.32。在限制每个测量只包括可比较项目后，测量之间的相关性更强（Spearman r = 0.55）。SCQ与指标入院时的资源利用措施、1年后的健康状况和资源利用有适度的相关性。SCQ与广泛使用的基于病历的合并症仪器以及随后的健康状况和使用情况有适度的相关性。这项新措施是评估临床和卫生服务研究中合并症的有效方法。在没有医疗记录的情况下，它将特别有用。
Objective. To develop the Self-Administered Comorbidity Questionnaire (SCQ) and assess its psychometric properties, including the predictive validity of the instrument, as reflected by its association with health status and health care utilization after 1 year.Methods. A cross-sectional comparison of the SCQ with a standard, chart abstraction-based measure (Charlson Index) was conducted on 170 inpatients from medical and surgical care units. The association of the SCQ with the chart-based comorbidity instrument and health status (short form 36) was evaluated cross sectionally. The association between these. measures and health status and resource utilization was assessed after 1 year.Results. The Spearman correlation coefficient for the association between the SCQ and the Charlson Index was 0.32. After restricting each measure to include only comparable items, the correlation between measures was stronger (Spearman r = 0.55). The SCQ had modest associations with measures of resource utilization during the index admission, and with health status and resource utilization after 1 year.Conclusion. The SCQ has modest correlations with a widely used medical record-based comorbidity instrument, and with subsequent health status and utilization. This new measure represents an efficient method to assess comorbid conditions in clinical and health services research. It will be particularly useful in settings where medical records are unavailable.
