Potentially inappropriate medication prescribing by nurse practitioners and physicians.

ABSTRACT:

Background

Potentially inappropriate medication (PIM) use is a risk factor for hospitalization and mortality. However, there were few studies focusing on the impact of provider type on PIM use.

Objective

We aimed to estimate the initial and refill PIM prescribing rate for physician visits and nurse practitioner (NP) visits and the impact of provider type on PIM prescribing.

Research design

We used 100% Texas Medicare data to define physician visits and NP visits in 2016. The rate of visits with a PIM prescription from the same provider was measured, distinguishing between initial and refill prescription to estimate the PIM rate and adjusted odds ratio (OR) by provider type.

Results

There were 24.1 per 1000 visits with a prescription for a PIM: 9.0 per 1000 visits for an initial PIM and 15.1 per 1000 visits for a refill PIM. A visit to an NP was less likely to result in an initial (OR = 0.74, 95% confidence interval [CI] = 0.70-0.79) or refill (OR = 0.54, 95% CI = 0.51-0.57) PIM. The association of lower odds of receiving a prescription for an initial PIM from an NP was substantially stronger among black enrollees than white enrollees (OR = 0.44, 95%CI = 0.30-0.65 for blacks and OR = 0.73, 95%CI = 0.68-0.78 for white enrollees). The association of an NP provider with lower odds of receiving a PIM refill was more pronounced in older patients and in those with more comorbidities.

Conclusions

NPs prescribed fewer initial PIMs and were less likely to refill a PIM after an outpatient visit than physicians. The lower odds of receiving PIMs during an NP visit varied by age, race/ethnicity, rurality, and number of comorbidities.
