Description: The use of resources by primary care providers in office settings is an important determinant of health care costs. Family nurse practitioners (FNPs) can reduce costs because they are less expensive to train than physicians, and have lower salaries. Whether direct cost savings result from differential use of resources by FNPs in providing patient care is not well established. This study examines resource use by FNPs and family practice physicians (FPPs) not in practice together, using two tracer conditions: hypertension and pharyngitis.

Using a cross-sectional quasi-experimental design with random samples of providers in six urban counties, the study examined data on visits, diagnostic tests, medications and consultations from over 500 cases for each tracer condition. Age, sex and types of secondary diagnoses were similar for both providers' patients, though FNP's patients had greater comorbidity. More FNP patients were MediCal and HMO members; more FPP patients had private insurance and Medicare.

Different patterns of resource use were evident. FNPs ordered more diagnostic tests, but used less complex tests. General measures were used substantially more by FNPs for both conditions. FNPs obtained more consults but the rate was very low for both providers. For hypertension, FNPs used fewer and less expensive drugs, and had slightly more visits over six months. Lower mean blood pressure and more visits with BP in control were achieved by FNPs. For pharyngitis, FNPs had fewer visits but used more non-prescription drugs for symptom relief, while FPPs used more antibiotics. The complication rate was the same.

Resource use scales were constructed combining tests, drugs, visits and consults; using California Relative Value Studies units and Pharmacy Blue Book prices. Using multiple regression, higher resource use in hypertension was best predicted by being a non-board certified physician, fewer years in practice, graduating from a prestige medical school, and being in private practice. In pharyngitis, the best predictors were having the physician billed for outside lab tests, having less belief in individual responsibility for health, more office visits per week, being a physician, and fewer years in practice.

FNPs had lower resource use, though their patients were more complex and their care outcomes were equivalent or better than FPPs. Cost savings offered by FNPs extend beyond training and salary to less costly health care management.
