Development and evaluation of Intensive Case Management Screening Sheet in the Japanese population

Is intensive case management screening sheet score associated with service intensity?

AIMS

Since April 2020, the new Japanese mental health system has used the Intensive Case Management Screening Sheet (ICMSS) to identify patients' needs for case management services. This study aimed to examine the association between ICMSS score and service intensity and compare the magnitude of association between ICMSS score and service intensity with other scales.

METHODS

We recruited patients who received case management services from a staff member in a psychiatric outpatient service, psychiatric day-care program, or outreach team based at one psychiatric hospital. Case management service needs and functioning were assessed using ICMSS, Global Assessment Functioning (GAF), and Personal and Social Performance (PSP). The case manager also documented all services received by the participant for 2 months. The association between each scale and service duration was examined. Furthermore, the magnitude of the association between each scale and service intensity was compared.

RESULTS

Overall, 138 participants were included in the analysis. The most common diagnosis was schizophrenia. Mean total service duration was weakly but significantly correlated with ICMSS (Spearman's ρ = 0.320), GAF (ρ = -0.198), and PSP (ρ = -0.275) scores. Poisson's regression models and postestimation testing showed that the coefficient for ICMSS score (B = 0.144; 95% CI = 0.141, 0.148) was significantly larger than the coefficients for GAF (B = -0.017, 95% CI = -0.017, -0.016, χ2  = 15.70, P < 0.001) and PSP (B=-0.016, 95% CI = -0.017, -0.016, χ2  = 14.64, P < 0.001) scores.

CONCLUSION

ICMSS may provide preliminary information on case management service needs, but the level of service should be based on the individual needs of each patient and shared decision-making between the patient and case manager.

Core services of intensive case management for people with mental illness: A network analysis

BACKGROUND

In intensive case management (ICM), users receive a wide variety of services of varying content, which makes it difficult to understand the global features of ICM programs.

AIMS

The aim of this study was to examine the features of ICM programs using network analysis.

METHODS

A total of 233 ICM users in two Japanese medical institutions were recruited to participate. All received services were recorded for 2 months. In the network analysis, nodes represented types of ICM services and edges between two nodes depicted when over 5% of participants received both types of services.

RESULTS

We found high centrality values for 'H5. Hospital-based counseling', 'O13. Outreach support for mental health medications', 'H13. Hospital-based support for mental health medication', 'T5. Counseling via telecommunication', 'H3. Hospital-based coordination of services in the medical institution' and 'T2. Coordination of services with other institutions via telecommunication'. These results indicated that these services were associated with various other types of services. Social functioning was related to 'O13. Outreach support for mental health medication', whereas need for ICM was related to 'H13. Hospital-based support for mental health medications', 'T5. Counseling via telecommunication' and 'T2. Coordination of services with other institutions via telecommunication'.

CONCLUSION

Based on these findings, we speculated that there are at least five types of core services in ICM: regular face-to-face contact, outreach services, hospital-based services, easy contacts and coordination. These findings clarified the features of ICM programs, which may help improve the understanding of case managers' practice.
