Background: To evaluate the impacts of nurse-led clinic and nurse-led prescription on hemoglobin A1c (HbA1c) control in type 2 diabetes.
Methods: We searched relevant publications in English and Chinese database and conducted meta-analysis by Stata 12.0. We divided the case groups of included studies into 2 categories according to the role of nurse: nurse-led clinic and nurse-led prescription. Nurse-led clinic was implemented on the basis of standard diabetes care provided by doctor, and control group also receive the standard diabetes care but without nurse-led clinic. The doctor mentioned above might work alone or in a health care team. Nurse-led prescription was prescribed by nurse independently and compared with that of doctor.
Results: The meta-analysis shown that, compared with the standard diabetes care, nurse-led clinic significantly decreases HbA1c level (standard mean difference [SMD] = -0.767; 95% confidence interval [CI]: -1.062, -0.471; P < .001). In subgroup analysis, nurse-led clinic also had positive impacts on controlling HbA1c level, no matter in developed countries (SMD = -0.353; 95% CI: -0.6, -0.106; P = .005) or developing countries (SMD = -1.114; 95% CI: -1.498, -0.73; P < .001). Additionally, there was no significant difference between nurse-led prescription and doctor prescription in controlling HbA1c levels (SMD = -0.203; 95% CI: -0.434, 0.029; P = .086).
Conclusion: The nurse-led clinic had positive significance for HbA1c control. Meanwhile, the impact of nurse-led prescription on controlling HbA1c is comparable to that of doctor. It is valuable to provide nurse-led clinic on the basis of standard diabetes care provided by doctor to better control HbA1c, and nurse-led prescription should be provided when doctor-led service is limited.
