Achievement of diabetes care goals is suboptimal globally. Diabetes-focused quality improvement (QI) is effective but remains untested in South Asia.


To compare the effect of a multicomponent QI strategy versus usual care on cardiometabolic profiles in patients with poorly controlled diabetes.


Parallel, open-label, pragmatic randomized, controlled trial. (ClinicalTrials.gov: NCT01212328)


Diabetes clinics in India and Pakistan.


1146 patients (575 in the intervention group and 571 in the usual care group) with type 2 diabetes and poor cardiometabolic profiles (glycated hemoglobin [HbA1c] level ≥8% plus systolic blood pressure [BP] ≥140 mm Hg and/or low-density lipoprotein cholesterol [LDLc] level ≥130 mg/dL).


Multicomponent QI strategy comprising nonphysician care coordinators and decision-support electronic health records.


Proportions achieving HbA1c level less than 7% plus BP less than 130/80 mm Hg and/or LDLc level less than 100 mg/dL (primary outcome); mean risk factor reductions, health-related quality of life (HRQL), and treatment satisfaction (secondary outcomes).


Baseline characteristics were similar between groups. Median diabetes duration was 7.0 years; 6.8% and 39.4% of participants had preexisting cardiovascular and microvascular disease, respectively; mean HbA1c level was 9.9%; mean BP was 143.3/81.7 mm Hg; and mean LDLc level was 122.4 mg/dL. Over a median of 28 months, a greater percentage of intervention participants achieved the primary outcome (18.2% vs. 8.1%; relative risk, 2.24 [95% CI, 1.71 to 2.92]). Compared with usual care, intervention participants achieved larger reductions in HbA1c level (−0.50% [CI, −0.69% to −0.32%]), systolic BP (−4.04 mm Hg [CI, −5.85 to −2.22 mm Hg]), diastolic BP (−2.03 mm Hg [CI, −3.00 to −1.05 mm Hg]), and LDLc level (−7.86 mg/dL [CI, −10.90 to −4.81 mg/dL]) and reported higher HRQL and treatment satisfaction.


Findings were confined to urban specialist diabetes clinics.


Multicomponent QI improves achievement of diabetes care goals, even in resource-challenged clinics.
