Insights
Pediatric heart transplant readmissions are common, especially within the first year and 30 days post-discharge. Infections are the leading cause, with infant transplant, longer hospital stays, and Hispanic ethnicity increasing readmission risk.
Area of Science:
- Pediatric Cardiology
- Transplant Surgery
- Health Outcomes Research
Background:
- Hospital readmission following pediatric heart transplantation is not well understood.
- Characterizing readmission patterns is crucial for developing targeted interventions.
- Previous studies lack comprehensive data on readmission causes and risk factors.
Purpose of the Study:
- To determine the incidence and identify risk factors for hospital readmission within 30 days and 1 year after pediatric heart transplantation.
- To analyze the primary indications for readmission in this vulnerable population.
- To inform strategies aimed at reducing readmission rates and improving post-transplant care.
Main Methods:
- Utilized data from the Clinical Trials in Organ Transplantation for Children (CTOTC-04) study.
- Analyzed readmission rates within 30 days and 1 year for 227 pediatric heart transplant recipients.
- Employed Cox proportional hazard models to identify independent risk factors for readmission.
Main Results:
- Over half (56.8%) of pediatric heart transplant recipients were readmitted within one year; 71 experienced multiple readmissions.
- The most frequent causes for readmission were infection (25.0%), rejection (10.6%), and fever without infection (6.2%).
- Risk factors for 1-year readmission included infant transplant, longer initial hospitalization, lower UNOS urgency status, and Hispanic ethnicity.
Conclusions:
- Hospital readmission is frequent in the first year post-pediatric heart transplant, with the highest risk in the initial 30 days.
- Infection is a more common reason for readmission than rejection, and death during readmission is infrequent.
- Identifying patient-specific risk factors can guide tailored strategies to minimize hospital readmissions and enhance long-term outcomes.
Abstract:
The frequency, indications, and outcomes for readmission following pediatric heart transplantation are poorly characterized. A better understanding of this phenomenon will help guide strategies to address the causes of readmission. Data from the Clinical Trials in Organ Transplantation for Children (CTOTC-04) multi-institutional collaborative study were utilized to determine incidence of, and risk factors for, hospital readmission within 30 days and 1 year from initial hospital discharge. Among 240 transplants at 8 centers, 227 subjects were discharged and had follow-up. 129 subjects (56.8%) were readmitted within one year; 71 had two or more readmissions. The 30-day and 1-year freedom from readmission were 70.5% (CI: 64.1%, 76.0%) and 42.2% (CI: 35.7%, 48.7%), respectively. The most common indications for readmissions were infection followed by rejection and fever without confirmed infection, accounting for 25.0%, 10.6%, and 6.2% of readmissions, respectively. Factors independently associated with increased risk of first readmission within 1 year (Cox proportional hazard model) were as follows: transplant in infancy (P = .05), longer transplant hospitalization (P = .04), lower UNOS urgency status (2/IB vs 1A) at transplant (P = .04), and Hispanic ethnicity (P = .05). Hospital readmission occurs frequently in the first year following discharge after heart transplantation with highest risk in the first 30 days. Infection is more common than rejection as cause for readmission, with death during readmission being rare. A number of patient factors are associated with higher risk of readmission. A fuller understanding of these risk factors may help tailor strategies to reduce unnecessary hospital readmission.
