Global case management: Hong Kong. Care for the hospital-discharged frail elders by nurse case managers: a process evaluation of a longitudinal case management service project.

Using quantitative and qualitative methodology, a study was conducted on the process of case management performed by nurse case managers on a group of 45 post-discharged frail elderly patients in 2001-2002. The quantitative data provided the common reasons for client-initiated telephone calls to nurse case managers and the nurse case managers' interventions to these calls. Qualitative data yielded 9 major themes on which a sequential and dynamic process model of case management was conceptualized. Another 7 thematic descriptions on essential factors for the successful implementation of case management were configured in a dual-dimensional framework of staff and structural factors.
