Health Care Hotspotting - A Randomized, Controlled Trial

Area of Science:

• Health Services Research
• Public Health Interventions
• Patient Care Management

Background:

• Superutilizers, patients with very high healthcare utilization, are a focus for cost reduction and quality improvement programs.
• The Camden Coalition's hotspotting program is a nationally recognized intervention for superutilizers, involving post-discharge care coordination and social service linkage.
• This program aims to improve health outcomes and reduce healthcare spending among high-need patient populations.

Purpose of the Study:

• To evaluate the effectiveness of the Camden Coalition's care-transition program in reducing hospital readmissions among superutilizers.
• To determine if the hotspotting intervention leads to a significant decrease in 180-day hospital readmission rates compared to usual care.
• To assess the impact of a multidisciplinary team approach on healthcare utilization for complex patients.

Main Methods:

• A randomized controlled trial was conducted with 800 hospitalized patients exhibiting complex medical and social conditions.
• Participants had at least one prior hospitalization within six months and were assigned to either the care-transition program or usual care.
• The primary outcome measured was hospital readmission within 180 days post-discharge.

Main Results:

• The 180-day hospital readmission rate was 62.3% for the intervention group and 61.7% for the usual care group.
• The difference in readmission rates between the groups was not statistically significant (0.82 percentage points).
• A misleading apparent decline in admissions within the intervention group was observed due to not accounting for a similar decline in the control group.

Conclusions:

• The randomized trial found no significant reduction in hospital readmission rates for patients receiving the care-transition program compared to usual care.
• The hotspotting intervention, as implemented, did not demonstrate improved healthcare quality in terms of readmission rates for superutilizers.
• Further research may be needed to refine or identify alternative strategies for managing high-cost, high-need patient populations effectively.
