Hospital Outcomes Project for the Elderly (HOPE): rationale and design for a prospective pooled analysis

Area of Science:

• Geriatric Medicine
• Clinical Trials
• Health Services Research

Background:

• Acutely ill elderly patients are at high risk for functional decline during hospitalization.
• Previous single-center trials have had limited statistical power to assess interventions.
• A collaborative approach is needed to improve outcomes for this vulnerable population.

Purpose of the Study:

• To describe a collaborative investigation of six clinical studies focused on reducing functional decline in acutely-ill hospitalized elderly patients.
• To utilize a pooled analysis of multicenter trials to enhance statistical power and generalizability.
• To examine the consistency of interventions and outcomes across different hospital settings.

Main Methods:

• A prospective, multicenter pooled analysis of six related intervention trials.
• Involved five university-affiliated and one community hospital.
• Included elderly patients (65-75 years) admitted for acute illnesses, with site-specific interventions targeting exercise, delirium detection, geriatric care units, and nursing programs.
• Functional status was the primary outcome measure.

Main Results:

• The Hospital Outcomes Project for the Elderly (HOPE) employed a prospective, multicenter design for innovative analysis.
• Qualitative comparisons across sites will enhance generalizability despite variations in populations and interventions.
• The pooled analysis offers greater statistical power than previous single-center trials.

Conclusions:

• The HOPE pooled analysis project provides a robust framework for evaluating interventions to reduce functional decline in hospitalized elderly patients.
• This multicenter approach enhances the ability to detect primary and secondary outcomes.
• Findings will improve understanding and consistency of geriatric care interventions across diverse settings.
