A meta-analysis of the effect of hospital-based case management on hospital length-of-stay and readmission

BACKGROUND

Although many hospital-based case management (CM) interventions have been studied, there is little work summarizing the effectiveness of these studies.

OBJECTIVES

The purpose of this study was to investigate the effect of hospital-based CM compared with usual care on length of hospital stay and readmission rate.

METHOD

A meta-analytic method was employed to analyze the effect sizes of CM intervention on outcomes. Eligible studies were retrieved using computerized database searches, footnote chasing, and contact with content experts. The authors reviewed the final 12 studies, and the effect size, 95% confidence interval (CI), sensitivity, homogeneity, and publication bias were analyzed.

RESULTS

The overall average weighted effect size on length of stay (LOS) was 0.094 with a 95% CI of -0.032 to 0.220. The overall odds ratio for readmission was 0.87 with a 95% CI of 0.69 to 1.04. Overall, hospital-based CM interventions were not significantly effective in reducing LOS and readmissions. However, CM for patients with heart failure (effect size of 0.241 with a 95% CI of 0.012 to 0.470) was significantly effective in reducing LOS, although it was not effective for stroke patients (effect size of -0.226 with a 95% CI of -0.542 to 0.089) and frail elders (effect size of 0.126 with a 95% CI of -0.073 to 0.324). Analysis indicated that in this meta-analysis publication bias was unlikely.

DISCUSSION

The findings of this meta-analysis demonstrate a 6% decrease in readmission rate for patients who received hospital-based CM interventions. Further meta-analytic studies are needed to investigate the effectiveness of CM on other outcomes.

The impact of a liaison nurse on ICU nurses' perceptions of discharge planning

The objective of the study was to examine the impact of a discharge liaison nurse on intensive care unit (ICU) nurses' perceptions of discharge planning. The discharge liaison nurse coordinated the discharge of patients from ICU to the ward, assisted with hospital discharge, provided clinical teaching and support to both ICU and ward nurses and supported patients and families during hospitalisation. A block intervention design was used. All ICU nurses within one Australian teaching hospital were surveyed prior to and following the implementation of the discharge liaison nurse. Measures included the perceptions of discharge planning scale and the general perceived self-efficacy scale. Following implementation of the liaison nurse, less nurses perceived that discharge planning in the ICU was premature (chi2(2, n=117)=7.759, p=0.021) and that ICU nurses lack an understanding of the discharge planning process (chi2(2, n=118)=15.557, p<0.001). Discharge planning was more frequently seen as the responsibility of the bedside nurse (chi2(2, n=115) =15.270, p<0.005) but there was greater recognition of discharge planning as a time consuming process (chi2(2, n=117)=8.560, p=0.015). Self efficacy in relation to discharge planning did not change over time. Some support was found for the role of the discharge liaison nurse in promoting attitudinal change towards discharge planning in the ICU. Future research is needed to investigate the processes by which the liaison nurse fosters attitudinal change and to document the actual discharge planning practices undertaken in ICU.

ICU nurses' perceptions of discharge planning: a preliminary study

The role that intensive care unit (ICU) nurses could play in hospital discharge planning remains relatively unexplored. Using a case study, all ICU nurses in one hospital were surveyed about their perceptions of their role in the discharge process. Over 70% of the 58 nurses who responded thought that discharge planning was both appropriate in the ICU and not premature. However, several obstacles including patient acuity, time constraints and limited experience with this process were evident. While ICU nurses are aptly placed to manage discharge planning, they cannot be expected to undertake this important role without a systematic approach to its implementation.

Patient problems and nurse interventions during acute care and discharge planning

Standardization and computerization of medical documentation has provided a method to describe patient care by naming and linking patients' needs with nursing interventions. This study used a standardized nursing classification system to describe the types and frequency of problems experienced by elders hospitalized and discharged to home and the interventions used by staff nurses and advanced practice nurses (APNs) as they provided acute care and discharge planning for these cardiac patients. The patients' hospital records and the APN logs were content analyzed and then coded using the Problem Classification Scheme and Intervention Scheme of the Omaha System. Patients experienced an average of 8.6 problems that required a total of 7,000 interventions in all four Omaha System intervention categories. The results provided a description of the most frequent problems experienced by the patients linked with the most common nursing interventions. The nature, complexity, and prevalence of patient problems and the importance of communication across settings are evident. In addition, the study findings increase understanding of the contribution of nurses to the care of hospitalized elders as they make the transition from hospital to home.
