Hospital readmission refers to a situation where a patient is discharged from a hospital but returns for treatment within a specific time frame, often within 30 days. This can occur due to complications from the original condition, inadequate follow-up care, or other health issues that arise after discharge. Reducing hospital readmissions is a key focus for healthcare providers, as frequent readmissions can indicate poor quality of care and lead to increased healthcare costs. Strategies to prevent readmissions include better discharge planning, patient education, and improved communication between healthcare providers and patients.
