Abstract

Objective

The aim of this study was to identify provider characteristics associated with hormone therapy prescribing.

Methods

The study design is cross-sectional. In December 2005, we mailed surveys to providers practicing in two integrated healthcare delivery systems located in the northwestern and northeastern United States; 379 responded (74%) and 249 (49% of total) granted access to their automated data. Data included provider demographics, practice characteristics, and perceptions about hormone therapy. Provider-specific annual hormone therapy prescribing frequency was calculated as days supply of hormone therapy filled divided by the number of visits (among women aged 45-80 y). Factors associated with higher rates of hormone therapy prescribing were identified using bivariate and multivariate analyses.

Results

We report results separately for primary care providers (internists and family practitioners) and obstetrician/gynecologists because significant correlates differed in these two groups. For both primary care providers and obstetrician/gynecologists, in multivariate analyses, hormone therapy prescribing varied by site (P < or = 0.002) and years at the healthcare organization (P < or = 0.01). For primary care providers only, higher hormone therapy prescribing was associated with reported expert knowledge of the hormone therapy trials (P < or = 0.001). For obstetrician/gynecologists, higher hormone therapy prescription was related to feeling well prepared to counsel women on hormone therapy (P < or = 0.007), believing that the risks of estrogen with progestogen had been exaggerated (P = 0.04), and seeing younger aged patients (P = 0.03).

Conclusions

After the release of the Women's Health Initiative findings and practicing under similar clinical guidelines, hormone therapy prescribing is associated with providers' confidence, practice location, and time with a healthcare organization.
