Readmissions refer to the phenomenon where a patient is admitted to the hospital for the same or a related condition shortly after being discharged. This can be a sign of poor quality of care, inadequate discharge planning, or lack of coordination between healthcare providers. Research in this area seeks to understand the factors contributing to readmissions, develop strategies to reduce them, and improve the overall quality of patient care and outcomes. Studies may examine the impact of patient factors, hospital practices, and healthcare policies on readmission rates, and identify interventions to prevent unnecessary readmissions.
