Early Infectious Diseases Specialty Intervention Is Associated With Shorter Hospital Stays and Lower Readmission...

Area of Science:

• Infectious Diseases
• Health Services Research
• Hospital Administration

Background:

• Infectious diseases (ID) physician intervention improves outcomes in Medicare patients.
• The impact of ID physician involvement on privately insured patients is less understood.
• This study focuses on privately insured individuals under 65 hospitalized with common infections.

Purpose of the Study:

• To assess if ID physician involvement leads to better outcomes in privately insured patients under 65.
• To compare outcomes based on the timing of ID intervention (early vs. late vs. none).

Main Methods:

• Retrospective analysis of administrative claims data from 2014.
• Inclusion of privately insured individuals under 65 with selected infections during an acute-care stay.
• Categorization of patients into early (by day 3), late (after day 3), or no ID intervention groups.
• Key outcomes: mortality, cost, length of stay, readmission rates, and total 30-day post-discharge costs.

Main Results:

• Early ID intervention was associated with shorter length of stay, lower spending, and reduced mortality during the index hospitalization compared to no intervention.
• Early ID intervention also led to fewer readmissions and lower post-discharge healthcare payments compared to late intervention.
• Patients receiving early ID intervention experienced significantly better outcomes across all measured metrics.

Conclusions:

• Early infectious diseases physician intervention is associated with improved outcomes for privately insured patients under 65.
• Key benefits include lower mortality rates, shorter hospital stays, reduced readmissions, and decreased overall healthcare spending.
• This highlights the value of timely ID consultation for this demographic.
