The Patient-Reported Incident in Hospital Instrument (PRIH-I): assessments of data quality, test–retest reliability and hospital-level reliability

The PRIH-I comprises 13 questions about patient-perceived incidents in hospitals, and can be easily and cost-effectively included in national patient-experience surveys with an acceptable increase in respondent burden. Although the missing-item rate and test-retest reliability were poor for several items, the hospital-level reliability was satisfactory for most of the items. The incident items contribute to a patient-reported incident index, with excellent data quality and hospital-level reliability.
