Systematic review of whether nurse practitioners working in primary care can provide equivalent care to doctors.
OBJECTIVE
To determine whether nurse practitioners can provide care at first point of contact equivalent to doctors in a primary care setting.


METHODS
Systematic review of randomised controlled trials and prospective observational studies.


METHODS
Cochrane controlled trials register, specialist register of trials maintained by Cochrane Effective Practice and Organisation of Care Group, Medline, Embase, CINAHL, science citation index, database of abstracts of reviews of effectiveness, national research register, hand searches, and published bibliographies.


METHODS
Randomised controlled trials and prospective observational studies comparing nurse practitioners and doctors providing care at first point of contact for patients with undifferentiated health problems in a primary care setting and providing data on one or more of the following outcomes: patient satisfaction, health status, costs, and process of care.


RESULTS
11 trials and 23 observational studies met all the inclusion criteria. Patients were more satisfied with care by a nurse practitioner (standardised mean difference 0.27, 95% confidence interval 0.07 to 0.47). No differences in health status were found. Nurse practitioners had longer consultations (weighted mean difference 3.67 minutes, 2.05 to 5.29) and made more investigations (odds ratio 1.22, 1.02 to 1.46) than did doctors. No differences were found in prescriptions, return consultations, or referrals. Quality of care was in some ways better for nurse practitioner consultations.


CONCLUSIONS
Increasing availability of nurse practitioners in primary care is likely to lead to high levels of patient satisfaction and high quality care.
