Recurrent readmissions in medical patients: a prospective study

Area of Science:

• Geriatric Medicine
• Internal Medicine
• Health Services Research

Background:

• Hospital readmissions represent a significant burden on healthcare systems.
• Previous hospitalization is a key indicator of increased risk for future readmissions.
• Identifying factors for recurrent readmissions is crucial for effective patient management.

Purpose of the Study:

• To determine predictors of recurrent unplanned hospital readmissions.
• Focus on medical patients with multiple recent hospitalizations.
• Identify targets for post-hospital interventions.

Main Methods:

• Prospective cohort study conducted in Australian teaching hospital acute medical wards.
• Included 142 inpatients aged 50 years or older with recent prior hospitalization.
• Assessed demographics, medical history, comorbidities, nutritional status, functional status, cognition, mood, and social factors post-discharge.

Main Results:

• 38.7% of participants experienced an unplanned readmission within six months.
• Multivariate analysis identified chronic disease (aOR 3.4), depressive symptoms (aOR 3.0), and underweight (aOR 12.7) as significant predictors.
• These factors remained significant after adjusting for age, length of stay, and functional status.

Conclusions:

• Multiple chronic conditions, depressive symptoms, and underweight status are significant risk factors for readmission in high-risk older medical patients.
• Post-hospital care strategies should incorporate interventions targeting nutritional status and mood.
• These targeted interventions may help reduce recurrent hospitalizations in this vulnerable population.
