Rapid (7-Day) Readmissions to an Inpatient Medical Service at a Tertiary, Academic Medical Center

Area of Science:

• Internal Medicine
• Healthcare Quality Improvement

Background:

• Rapid hospital readmissions within 7 days are linked to increased morbidity and mortality.
• Understanding the drivers of these readmissions is crucial for improving patient outcomes and healthcare efficiency.

Purpose of the Study:

• To identify the primary causes of rapid (7-day) hospital readmissions.
• To specifically investigate the role of clinical judgment errors in these readmissions.
• To inform strategies for enhancing discharge practices and reducing readmission rates.

Main Methods:

• Retrospective review of 371 patient records from an inpatient medical service.
• Analysis of patients readmitted within 7 days of discharge.
• Classification of readmission causes into 10 categories, including diagnostic/therapeutic errors.

Main Results:

• Disease severity or treatment failure accounted for 50% of rapid readmissions.
• Adherence issues, high hospital utilization, and substance use/psychiatric conditions contributed to 32.4%.
• Clinical judgment errors were identified in 6.5% of readmissions (24 cases), involving diagnostic and therapeutic mistakes with infections, diabetes, and anticoagulation management.

Conclusions:

• The majority of rapid readmissions are primarily driven by the severity of the patient's condition during the initial hospitalization.
• Clinical judgment errors represent an infrequent but significant cause, particularly concerning high-risk medications and symptoms demanding heightened clinician vigilance.
