Effectiveness of multidisciplinary team case management: difference-in-differences analysis.

Area of Science:

• Health Services Research
• Clinical Management
• Public Health

Background:

• High-risk patients often incur substantial healthcare costs.
• Effective interventions are needed to manage complex patient needs and reduce hospital utilization.
• Multidisciplinary team (MDT) case management is a strategy employed to coordinate care for such populations.

Purpose of the Study:

• To evaluate the effectiveness of a multidisciplinary team (MDT) case management intervention for high-risk patients.
• To assess both direct effects on individual patients and indirect (spillover) effects at the practice level.
• To determine the clinical significance and cost-effectiveness of the intervention.

Main Methods:

• A difference-in-differences design was used, analyzing hospital admissions data.
• Individual-level analysis involved propensity score matching for 2049 intervention patients against control patients.
• Practice-level analysis compared 30 practices using a staged implementation natural experiment.

Main Results:

• At the individual level, the intervention showed clinically trivial increases in inpatient non-elective admissions and 30-day re-admissions.
• No evidence suggested that the highest-risk patients benefited more from the intervention.
• A small, non-robust decrease in inpatient non-elective admissions was observed at the practice level.

Conclusions:

• The multidisciplinary team (MDT) case management intervention did not meet its primary objective of improving outcomes for high-risk patients.
• The clinical significance and cost-effectiveness of the observed small practice-level effects are questionable.
• There is a continued need for developing effective strategies to reduce secondary care utilization in high-risk populations.
