Some research provided robust analyses of the affected population s ’ health inequities and demonstrated how a task shifting intervention redressed those concerns .
Introduction Task shifting interventions have been implemented to improve health and address health inequities .
Little is known about how inequity and vulnerability are defined and measured in research on task shifting .
We conducted a systematic review to identify how inequity and vulnerability are identified , defined and measured in  task shifting research from high-income countries .
Randomized Controlled Trial of a Community Health Worker Self-Management Support Intervention Among Low-Income Adults With Diabetes, Seattle, Washington, 2010–2014
Introduction Community health workers ( CHWs ) can improve diabetes outcomes ; however , questions remain about translating research findings into practical low-intensity models for safety-net providers . We tested the effectiveness of a home-based low-intensity CHW intervention for improving health outcomes among low-income adults with diabetes . Methods Low-income patients with glycated hemoglobin A1c ( HbA1c ) of 8.0 % or higher in the 12 months before enrollment from 3 safety-net providers were r and omized to a 12-month CHW-delivered diabetes self-management intervention or usual care . CHWs were based at a local health department . The primary outcome was change in HbA1c from baseline enrollment to 12 months ; secondary outcomes included blood pressure and lipid levels , quality of life , and health care use . Results The change in HbA1c in the intervention group ( n = 145 ) ( unadjusted mean of 9.09 % to 8.58 % , change of −0.51 ) compared with the control group ( n = 142 ) ( 9.04 % to 8.71 % , change of −0.33 ) was not significant ( P = .54 ) . In an analysis of participants with poor glycemic control ( HbA1c > 10 % ) , the intervention group had a 1.23-point greater decrease in HbA1c compared with controls ( P = .046 ) . For the entire study population , we found a decrease in reported physician visits ( P < .001 ) and no improvement in health-related quality of life ( P = .07 ) in the intervention group compared with the control group . Conclusion A low-intensity CHW-delivered intervention to support diabetes self-management did not significantly improve HbA1c relative to usual care . Among the subgroup of participants with poor glycemic control ( HbA1c > 10 % at baseline ) , the intervention was effective
