Advanced practice providers spend significant time on prior authorizations (PAs). This study found no correlation between PA methods, time spent, and approval rates, indicating a need for more efficient processes.
Area of Science:
- Health Services Research
- Clinical Practice Management
Background:
- Advanced practice providers (APPs) are increasingly managing prior authorizations (PAs).
- The administrative burden of PAs impacts clinical workflow and resource allocation.
Purpose of the Study:
- To investigate the relationship between prior authorization processes and approval outcomes.
- To determine if the time spent on PAs correlates with their approval rates.
Main Methods:
- Data collected on PA variables including type, method, time, peer-to-peer reviews, and outcomes.
- Statistical analyses included Chi-square tests and 2-sample t-tests.
- Study focused on PAs completed by a nurse practitioner in one region.
Main Results:
- No significant association was found between the method of PA request and time spent.
- The number of attempts did not correlate with the time spent on approved PAs.
- Time spent on prior authorizations did not significantly predict approval outcomes.
Conclusions:
- Current prior authorization processes do not show a correlation between time invested and successful approval.
- Further research is required to identify strategies for reducing the time and opportunity costs associated with PAs.
- Optimizing PA workflows is essential for improving APP efficiency and patient care.
