Results of a successful telephonic intervention to improve diabetes control in urban adults: a randomized trial.

ABSTRACT: To compare the effectiveness of a telephonic and a print intervention over 1 year to improve diabetes control in low-income urban adults.A randomized trial in Spanish and English comparing a telephonic intervention implemented by health educators with a print intervention. Participants (N = 526) had an A1C ?7.5% and were prescribed one or more oral agents. All were members of a union/employer jointly sponsored health benefit plan. Health coverage included medications. Primary outcomes were A1C and pharmacy claims data; secondary outcomes included self-report of two medication adherence measures and other self-care behaviors.Participants were 62% black and 23% Hispanic; 77% were foreign born, and 42% had annual family incomes <$30 thousand. Baseline median A1C was 8.6% (interquartile range 8.0-10.0). Insulin was also prescribed for 24% of participants. The telephone group had mean ± SE decline in A1C of 0.23 ± 0.11% over 1 year compared with a rise of 0.13 ± 0.13% for the print group (P = 0.04). After adjusting for baseline A1C, sex, age, and insulin use, the difference in A1C was 0.40% (95% CI 0.10-0.70, P = 0.009). Change in medication adherence measured by claims data, but not by self-report measures, was significantly associated with change in A1C (P = 0.01). Improvement in medication adherence was associated (P = 0.005) with the telephonic intervention, but only among those not taking insulin. No diabetes self-care activities were significantly correlated with the change in A1C.A 1-year tailored telephonic intervention implemented by health educators was successful in significantly, albeit modestly, improving diabetes control compared with a print intervention in a low-income, insured, minority population.

Project description:AimsTo assess the intervention effects of BREATHE (BRief intervention to Evaluate Asthma THErapy), a novel brief shared decision-making intervention and evaluate feasibility and acceptability of intervention procedures.DesignGroup-randomized longitudinal pilot study.MethodsIn total, 80 adults with uncontrolled persistent asthma participated in a trial comparing BREATHE (N = 40) to a dose-matched attention control intervention (N = 40). BREATHE is a one-time shared decision-making intervention delivered by clinicians during routine office visits. Ten clinicians were randomized and trained on BREATHE or the control condition. Participants were followed monthly for 3 months post-intervention. Data were collected from December 2017 - May 2019 and included surveys, lung function tests, and interviews.ResultsParticipants were Black/multiracial (100%) mostly female (83%) adults (mean age 45). BREATHE clinicians delivered BREATHE to all 40 participants with fidelity based on expert review of audiorecordings. While the control group reported improvements in asthma control at 1-month and 3-month follow-up, only BREATHE participants had better asthma control at each timepoint (β = 0.77; standard error (SE)[0.17]; p ≤ 0.0001; β = 0.71; SE[0.16]; p ≤ 0.0001; β = 0.54; SE[0.15]; p = .0004), exceeding the minimally important difference. BREATHE participants also perceived greater shared decision-making occurred during the intervention visit (β = 7.39; SE[3.51]; p = .03) and fewer symptoms at follow-up (e.g., fewer nights woken, less shortness of breath and less severity of symptoms) than the controls. Both groups reported improved adherence and fewer erroneous medication beliefs.ConclusionBREATHE is a promising brief tailored intervention that can be integrated into office visits using clinicians as interventionists. Thus, BREATHE offers a pragmatic approach to improving asthma outcomes and shared decision-making in a health disparity population.ImpactThe study addressed the important problem of uncontrolled asthma in a high-risk vulnerable population. Compared with the dose-matched attention control condition, participants receiving the novel brief tailored shared decision-making intervention had significant improvements in asthma outcomes and greater perceived engagement in shared decision-making. Brief interventions integrated into office visits and delivered by clinicians may offer a pragmatic approach to narrowing health disparity gaps. Future studies where other team members (e.g., office nurses, social workers) are trained in shared decision-making may address important implementation science challenges as it relates to adoption, maintenance, and dissemination.

Project description:Scalable self-management interventions are necessary to address suboptimal diabetes control, especially among minority populations. The study tested the effectiveness of a telephone behavioral intervention in improving glycemic control among adults with diabetes in the New York City A1c Registry.RCT comparing a telephone intervention to print-only intervention in the context of the A1c Registry program.Nine hundred forty-one adults with diabetes and hemoglobin A1c (A1c) >7% from a low-income, predominantly Latino population in the South Bronx were recruited from the A1c Registry.All study participants were mailed print diabetes self-management materials at baseline and modest lifestyle incentives quarterly. Only the telephone participants received four calls from health educators evenly spaced over 1 year if baseline A1c was >7%-9%, or eight calls if baseline A1c was >9%. Medication adherence was the main behavioral focus and, secondarily, nutrition and exercise.Primary outcome was difference between two study arms in change in A1c from baseline to 1 year. Secondary outcomes included diabetes self-care activities, including self-reported medication adherence. Data were collected in 2008-2012 and analyzed in 2012-2014.Participants were predominantly Latino (67.7%) or non-Latino black (28%), with 69.7% foreign-born and 55.1% Spanish-speaking. Among 694 (74%) participants with follow-up A1c, mean A1c decreased by 0.9 (SD=0.1) among the telephone group compared with 0.5 (SD=0.1) among the print-only group, a difference of 0.4 (95% CI=0.09, 0.74, p=0.01). The intervention had significant effect when baseline A1c was >9%. Both groups experienced similar improvements in self-care activities, medication adherence, and intensification.A telephone intervention delivered by health educators can be a clinically effective tool to improve diabetes control in diverse populations, specifically for those with worse metabolic control identified using a registry. This public health approach could be adopted by health systems supported by electronic record capabilities. CLINICALTRIALS.NCT00797888.

Project description:BackgroundDiagnoses of Type 2 Diabetes in the United States have more than doubled in the last two decades. One minority group at disproportionate risk are Pacific Islanders who face numerous barriers to prevention and self-care. To address the need for prevention and treatment in this group, and building on the family-centered culture, we will pilot test an adolescent-mediated intervention designed to improve the glycemic control and self-care practices of a paired adult family member with diagnosed diabetes.MethodsWe will conduct a randomized controlled trial in American Samoa among n = 160 dyads (adolescent without diabetes, adult with diabetes). Adolescents will receive either a six-month diabetes intervention or a leadership and life skills-focused control curriculum. Aside from research assessments we will have no contact with the adults in the dyad who will proceed with their usual care. To test our hypothesis that adolescents will be effective conduits of diabetes knowledge and will support their paired adult in the adoption of self-care strategies, our primary efficacy outcomes will be adult glycemic control and cardiovascular risk factors (BMI, blood pressure, waist circumference). Secondarily, since we believe exposure to the intervention may encourage positive behavior change in the adolescent themselves, we will measure the same outcomes in adolescents. Outcomes will be measured at baseline, after active intervention (six months post-randomization) and at 12-months post-randomization to examine maintenance effects. To determine potential for sustainability and scale up, we will examine intervention acceptability, feasibility, fidelity, reach, and cost.DiscussionThis study will explore Samoan adolescents' ability to act as agents of familial health behavior change. Intervention success would produce a scalable program with potential for replication in other family-centered ethnic minority groups across the US who are the ideal beneficiaries of innovations to reduce chronic disease risk and eliminate health disparities.
