Community Health Workers Versus Nurses as Counselors or Case Managers in a Self-Help Diabetes Management Program.
OBJECTIVES To confirm the effectiveness of community health workers ' involvement as counselors or case managers in a self-help diabetes management program in 2009 to 2014 . METHODS Our open-label , r and omized controlled trial determined the effectiveness of a self-help intervention among Korean Americans aged 35 to 80 years in the Baltimore-Washington metropolitan area with uncontrolled type 2 diabetes . We measured and analyzed physiological and psychobehavioral health outcomes of the  community health worker-counseled ( n = 54 ) and registered nurse (RN)-counseled ( n = 51 ) intervention groups in comparison with the control group ( n = 104 ) . RESULTS The community health workers ' performance was comparable to that of the RNs for both psychobehavioral outcomes ( e.g. , self-efficacy , quality of life ) and physiological outcomes . The community health worker-counseled group showed hemoglobin A1C reductions from baseline ( -1.2 % , -1.5 % , -1.3 % , and -1.6 % , at months 3 , 6 , 9 , and 12 , respectively ) , all of which were greater than reductions in the RN-counseled ( -0.7 % , -0.9 % , -0.9 % , and -1.0 % ) or the control ( -0.5 % , -0.5 % , -0.6 % , and -0.7 % ) groups . CONCLUSIONS Community health workers performed as well as or better than nurses as counselors or case managers in a self-help diabetes management program in a Korean American community
