Theoretical concepts and instruments for measuring hospital discharge readiness: A scoping review

Background: The Discharge Readiness of adult patients in a hospital setting is a multidimensional concept which is becoming increasingly important internationally as part of discharge planning. To date, there has been a lack of reviews of existing measurement instruments as well as theoretical concepts of discharge readiness. Objective: To provide an overview of existing measurement instruments and theoretical concepts regarding readiness for hospital discharge in adult patients. Design and methods: A scoping review was conducted in accordance with the Joanna Briggs Institute methodological manual and PRISMA ScR reporting principles. A literature search was conducted using the CINAHL and LIVIVO databases (including MEDLINE and PSYINDEX) in October 2021. After test screening, all identified articles were screened by two independent reviewers using predefined inclusion and exclusion criteria before the content was extracted and mapped. Results: Of the 1823 records identified, 107 were included in this review. Of these, 30 studies were included as development or validation studies of measurement instruments assessing discharge readiness, 68 were included as empirical studies with readiness for hospital discharge as the primary outcome or key concept, and nine publications were included as theoretical papers or reviews. Five dimensions of readiness for hospital discharge were extracted:1) Physical, 2) Psychological, 3) Education and Knowledge, 4) Adequate Individual Support, and 5) Social and Organisational Determinants. Of the 47 instruments identified for measuring discharge readiness, 33 were validated. The Readiness for Hospital Discharge Scale (RHDS) was the most frequently used instrument. Conclusions: The systematic measurement of readiness for hospital discharge, particularly from the patient's perspective combined with the nurse's perspective, might be useful in reducing negative outcomes such as readmissions. This review provides an overview of existing and validated instruments for the systematic assessment of discharge readiness in acute inpatient care, as well as an overview of the theoretical concepts of readiness for hospital discharge. Further research is needed on the relationship between organisational determinants and readiness for discharge.
