Physician associates (PAs) and nurse practitioners (NPs) are widely used in liver transplant care. A dedicated PA and NP team was associated with a shorter length of stay, suggesting potential cost savings.
Area of Science:
- Transplant Surgery
- Healthcare Management
- Clinical Practice
Background:
- Physician associates (PAs) and nurse practitioners (NPs) play an increasing role in specialized medical fields.
- Their integration into liver transplant programs is not fully characterized, particularly regarding their financial impact.
Purpose of the Study:
- To assess the utilization and perceptions of PAs and NPs in liver transplant centers.
- To determine the financial effect of employing PAs and NPs in liver transplant care.
Main Methods:
- A survey was distributed to leaders of liver transplant programs (performing ≥25 transplants in 2020).
- A single-center retrospective analysis compared length of stay (LOS) and readmission rates before and after implementing a dedicated PA team for liver and simultaneous liver-kidney transplants.
- Statistical analyses included chi-square and t-tests.
Main Results:
- The survey achieved a 77% response rate, with 98% of institutions reporting the use of PAs and NPs.
- The retrospective analysis revealed a significantly shorter mean LOS post-transplant in the cohort with a dedicated PA team (P = .0005).
- No significant difference was observed in 30-day readmission rates.
Conclusions:
- PAs and NPs are broadly integrated into the post-liver transplant care continuum.
- The reduction in LOS suggests that a dedicated PA and NP team may offer a financial benefit and contribute to cost savings in liver transplantation.
