Longitudinal Analysis of Quality of Diabetes Care and Relational Climate in Primary Care

To assess the influence of relational climate on quality of diabetes care. The study was conducted at the Department of Veterans Affairs (VA). The VA All Employee Survey (AES) was used to measure relational climate. Patient and facility characteristics were gathered from VA administrative datasets. Multilevel panel data (2008-2012) with patients nested into clinics. Diabetic patients were identified using ICD-9 codes and assigned to the clinic with the highest frequency of primary care visits. Multiple quality indicators were used, including an all-or-none process measure capturing guideline compliance, the actual number of tests and procedures, and three intermediate continuous outcomes (cholesterol, glycated hemoglobin, and blood pressure). The study sample included 327,805 patients, 212 primary care clinics, and 101 parent facilities in 2010. Across all study years, there were 1,568,180 observations. Clinics with the highest relational climate were 25 percent more likely to provide guideline-compliant care than those with the lowest relational climate (OR for a 1-unit increase: 1.02, p-value <.001). Among insulin-dependent diabetic veterans, this effect was twice as large. Contrary to that expected, relational climate did not influence intermediate outcomes. Relational climate is positively associated with tests and procedures provision, but not with intermediate outcomes of diabetes care.

Fidelity of implementation to a care team redesign and improved outcomes of diabetes care.

We assessed fidelity of implementation (FOI) to the intended features of a primary care team redesign that integrated registered nurse care managers and patient health coaches onto existing care teams. The relation of FOI ranking and improvements in intermediate outcomes of diabetes care was examined. We assessed FOI by interviewing frontline primary care team members (n = 20). We explored the relation of FOI and outcomes of diabetes care (n = 10 206 patients) over a 3-year period (2010-12). Multilevel, multivariate regression estimated the relation of FOI and improvements in outcomes of diabetes care. Five primary care practices in greater Los Angeles, CA, USA. Ten thousand, two hundred and six adult patients with diabetes; 20 frontline primary care clinicians and staff. Blood pressure, hemoglobin A1c (HbA1c) and low-density lipoprotein cholesterol (LDL-C) control among adult diabetic patients. All practices improved diabetic patients' LDL-C control over time. In adjusted analyses, the practice with the highest FOI achieved the largest improvement in blood pressure and HbA1c control among diabetic patients. In contrast, the practice with the lowest FOI had the least improvements in blood pressure, HbA1c and LDL-C control. FOI was an inconsistent predictor of intermediate outcomes of diabetes care for other practices. FOI assessment can be useful for identifying low FOI to a redesign so that technical assistance and resources can be provided to improve team functioning and patient outcomes. High FOI can enable greater improvements in patient outcomes in the context of primary care practice redesign.

Revisit frequency and its association with quality of care among diabetic patients: Translating Research Into Action for Diabetes (TRIAD)

ObjectiveTo describe patient and provider characteristics associated with outpatient revisit frequency and to examine the associations between the revisit frequency and the processes and intermediate outcomes of diabetes care. Research design and methodsWe analyzed data from Translating Research Into Action for Diabetes (TRIAD), a prospective, multicenter, observational study of diabetes care in managed care. ResultsOur analysis included 6040 eligible adult participants with type 2 diabetes (42.6%≥65years of age, 54.1% female) whose primary care providers were the main provider of the participants’ diabetes care. The median (interquartile range) revisit frequency was 4.0 (3.7, 6.0) visits per year. Being female, having lower education, lower income, more complex diabetes treatment, cardiovascular disease, higher Charlson comorbidity index, and impaired mobility were associated with higher revisit frequency. The proportion of participants who had annual assessments of HbA1c and LDL-cholesterol, foot examinations, advised or documented aspirin use, and influenza immunizations were higher for those with higher revisit frequency. The proportion of participants who met HbA1c (<9.5%) and LDL-cholesterol (<130mg/dL) treatment goals were higher for those with a higher revisit frequency. The predicted probabilities of achieving more aggressive goals, HbA1c <8.5%, LDL-cholesterol <100mg/dL, and blood pressure <130/85 or even <140/90mmHg were not associated with higher revisit frequency. ConclusionsRevisit frequency was highly variable and was associated with both sociodemographic characteristics and disease severity. A higher revisit frequency was associated with better processes of diabetes care, but the association with intermediate outcomes was less clear.

Racial Comparisons of Diabetes Care and Intermediate Outcomes in a Patient-Centered Medical Home

OBJECTIVETo assess racial differences in diabetes processes and intermediate outcomes of care in an internal medicine, patient-centered medical home (PCMH) group practice.RESEARCH DESIGN AND METHODSWe conducted a retrospective cohort study of 1,457 adults with diabetes receiving care from 89 medical providers within a PCMH-designated academic practice between 1 July 2009 and 31 July 2010. We used mixed models to assess independent associations between patient race (non-Hispanic white or black) and 1) receipt of processes of care (A1C and LDL testing, foot and retinal examination, and influenza and pneumococcal vaccination) and 2) achievement of intermediate outcomes (LDL <100 mg/dL, blood pressure [BP] <140/90 mmHg, A1C <7.0% [<53 mmol/mol], and A1C >9.0% [>75 mmol/mol]), controlling for sociodemographic factors, health status, treatment intensity, and clinical continuity.RESULTSCompared with non-Hispanic white patients, black patients were younger, were more often single, had lower educational attainment, and were less likely to have commercial insurance. In unadjusted analyses, fewer black patients received a retinal examination and influenza vaccination during the study period or any lifetime pneumococcal vaccination (P < 0.05 [all comparisons]). Fewer black patients achieved an LDL <100 mg/dL, BP <140/90 mmHg, or A1C <7.0% (<53 mmol/mol), while more black patients had an A1C >9.0% (>75 mmol/mol) (P < 0.05 [all comparisons]). In multivariable models, black patients were less likely to receive A1C testing (odds ratio [OR] 0.57 [95% CI 0.34–0.95]) or influenza vaccination (OR 0.75 [95% CI 0.57–0.99]) or to achieve an LDL <100 mg/dL (OR 0.74 [95% CI 0.55–0.99]) or BP <140/90 mmHg (OR 0.64 [95% CI 0.49–0.84]).CONCLUSIONSRacial differences in processes and intermediate outcomes of diabetes care were present within this PCMH-designated practice, controlling for differences in sociodemographic, clinical, and treatment factors.

Improving diabetes management with electronic medical records

Most primary-care physicians have adopted electronic medical records (EMRs) for the management of patients in ambulatory care. Observational trials suggest that the use of EMRs improves the achievement of the recommended standards of diabetes care and intermediate outcomes. A French group of general practitioners has shown, in a randomized controlled trial of diabetes care, the beneficial effects of a follow-up module integrated into an EMR. Electronic reminders, eHealth technology and e-mail messaging to patients integrated into the EMR have also been reported to have a beneficial effect on diabetes care. Some recommendations have been devised for the meaningful use of EMRs to improve the process and, possibly, intermediate outcomes of diabetes care as well. Another potential benefit to consider is the extraction and aggregation of data to create diabetes registers. Large regional and national diabetes registers have been set up in the US and Europe for various purposes, including patient recall, description of care patterns and outcomes, improvement of practices, drug safety, observational research and retrospective trials. In France, the government initiative towards an Internet-based personal health record (PHR) provides an appropriate framework for implementing and sharing the information needed to improve diabetes care, such as electronic summaries of health information, personalized health plans (PHPs), and standardized and structured hospital-discharge forms. All of these materials can be generated from EMRs. The widespread and optimalized use of EMRs for diabetes care with links to the national diabetes register and the capacity to supply PHRs are major considerations. Achieving these goals requires a common initiative comprising primary care and diabetes scientific societies in cooperation with diabetes patients'associations.

Analysis of a primary care led diabetes annual review programme in a multi ethnic cohort in Wellington, New Zealand

Introduction In 2000 a primary care led “Get Checked” programme of free annual diabetes reviews was introduced in New Zealand. This report explores changes in clinical variables over five annual visits in relation to ethnicity. Methods From 19,054 people in the Wellington region all 2967 with Type 2 diabetes completing five visits between 2000 and 2006 contributed data. This included weight, blood pressure, HbA1c, lipids, and urinary albumin:creatinine ratio. Mixed linear models examined changes in clinical variables by visit and the relationships with ethnicity. Results Of the 2967, 69.5% were European, 10.0% Maori, 8.6% Pacific and 10.4% Asian. Weight, systolic and diastolic blood pressure declined. HbA1c initially declined with time in Maori, Pacific and Asian and then rose. Total cholesterol decreased and HDL cholesterol rose. Urinary albumin:creatinine ratio fell at first and then rose and the degree of change was dependent on ethnicity. Use of diabetes medications and ACE inhibitor prescription increased in all ethnicities. Statin prescriptions rose from 20 to 61%. Current smoking rates fell from 10.7% to 9.4%. Conclusion This programme showed improvements in intermediate outcomes of diabetes care across all ethnic groups highlighting the benefit of reducing barriers to, and increasing engagement with, good primary health care.

Outpatient EHR-Based Diabetes Clinical Decision Support That Works: Lessons Learned From Implementing Diabetes Wizard

In Brief Electronic health record-based clinical decision support (CDS) can improve key intermediate outcomes of diabetes care in primary care settings and could be deployed in conjunction with additional care improvement strategies. It is important to understand how to incorporate CDS strategies into primary care practices to obtain high provider use rates and satisfaction. This article describes the process for successful implementation of a CDS tool called Diabetes Wizard.

Effect of Advanced Access Scheduling on Processes and Intermediate Outcomes of Diabetes Care and Utilization

The impact of open access (OA) scheduling on chronic disease care and outcomes has not been studied. To assess the effect of OA implementation at 1 year on: (1) diabetes care processes (testing for A1c, LDL, and urine microalbumin), (2) intermediate outcomes of diabetes care (SBP, A1c, and LDL level), and (3) health-care utilization (ED visits, hospitalization, and outpatient visits). We used a retrospective cohort study design to compare process and outcomes for 4,060 continuously enrolled adult patients with diabetes from six OA clinics and six control clinics. Using a generalized linear model framework, data were modeled with linear regression for continuous, logistic regression for dichotomous, and Poisson regression for utilization outcomes. Patients in the OA clinics were older, with a higher percentage being African American (51% vs 34%) and on insulin. In multivariate analyses, for A1c testing, the odds ratio for African-American patients in OA clinics was 0.47 (CI: 0.29-0.77), compared to non-African Americans [OR 0.27 (CI: 0.21-0.36)]. For urine microablumin, the odds ratio for non-African Americans in OA clinics was 0.37 (CI: 0.17-0.81). At 1 year, in adjusted analyses, patients in OA clinics had significantly higher SBP (mean 6.4 mmHg, 95% CI 5.4 - 7.5). There were no differences by clinic type in any of the three health-care utilization outcomes. OA scheduling was associated with worse processes of care and SBP at 1 year. OA clinic scheduling should be examined more critically in larger systems of care, multiple health-care settings, and/or in a randomized controlled trial.

Impact of Pay for Performance on Ethnic Disparities in Intermediate Outcomes for Diabetes: A Longitudinal Study

OBJECTIVE—The purpose of this study was to examine the impact of a major pay for performance incentive on trends in the quality of diabetes care in white, black, and South Asian ethnic groups in an urban setting in the U.K.RESEARCH DESIGN AND METHODS—We developed longitudinal models examining the quality of diabetes care in a cohort of ethnically diverse patients in Southwest London using electronic family practice records. Outcome measures were mean blood pressure and A1C values between 2000 and 2005.RESULTS—The introduction of pay for performance was associated with reductions in mean systolic and diastolic blood pressure, which were significantly greater than those predicted by the underlying trend in the white (−5.8 and −4.2 mmHg), black (−2.5 and −2.4 mmHg), and South Asian (−5.5 and −3.3 mmHg) groups. Reductions in A1C levels were significantly greater than those predicted by the underlying trend in the white group (−0.5%) but not in the black (−0.3%) or South Asian (−0.4%) groups. Ethnic group disparities in annual measurement of blood pressure and A1C were abolished before the introduction of pay for performance.CONCLUSIONS—The introduction of a pay for performance incentive in U.K. primary care was associated with improvements in the intermediate outcomes of diabetes care for all ethnic groups. However, the magnitude of improvement appeared to differ between ethnic groups, thus potentially widening existing disparities in care. Policy makers should consider the potential impacts of pay for performance incentives on health disparities when designing and evaluating such programs.

Use of Chronic Care Model Elements Is Associated With Higher-Quality Care for Diabetes

In 30 small, independent primary care practices, we examined the association between clinician-reported use of elements of the Chronic Care Model (CCM) and diabetic patients' hemoglobin A(1c) (HbA(1c)) and lipid levels and self-reported receipt of care. Ninety clinicians (60 physicians, 17 nurse-practitioners, and 13 physician's assistants) completed a questionnaire assessing their use of elements of the CCM on a 5-point scale (never, rarely, occasionally, usually, and always). A total of 886 diabetic patients reported their receipt of various diabetes care services. We computed a clinical care composite score that included patient-reported assessments of blood pressure, lipids, microalbumin, and HbA(1c); foot examinations; and dilated retinal examinations. We computed a behavioral care composite score from patient-reported support from their clinician in setting self-management goals, obtaining nutrition education or therapy, and receiving encouragement to self-monitor their glucose. HbA(1c) values and lipid profiles were obtained by independent laboratory assay. We used multilevel regression models for analyses to account for the hierarchical nature of the data. Clinician-reported use of elements of CCM was significantly associated with lower HbA(1c) values (P = .002) and ratios of total cholesterol to high-density lipoprotein cholesterol (P = .02). For every unit increase in clinician-reported CCM use (eg, from "rarely" to "occasionally"), there was an associated 0.30% reduction in HbA(1c) value and 0.17 reduction in the lipid ratio. Clinician use of the CCM elements was also significantly associated with the behavioral composite score (P = .001) and was marginally associated with the clinical care composite score (P = .07). Clinicians in small independent primary care practices are able to incorporate elements of the CCM into their practice style, often without major structural change in the practice, and this incorporation is associated with higher levels of recommended processes and better intermediate outcomes of diabetes care.

Measuring the quality of diabetes care in urban and rural Indian health programs.

The purpose of this study was to compare the quality of diabetes care provided to American Indians/Alaska Natives (AI/AN) by urban and rural Indian health programs. Medical record review data collected by the Indian Health Service as part of the Diabetes Care and Outcomes Audit in 2002. Seventeen urban Indian health clinics and 225 rural Indian health programs. All urban AI/AN patients (n = 710) and random sample records of rural AI/AN patients (n=1420). Adherence to guidelines for process measures and intermediate outcomes of diabetes care. Compared to the rural sample, urban patients were more likely to have received diabetes education during the prior year (P < or = .05). Annual dental examinations were less common among urban patients than rural patients (19% vs 41%, P < or = .001). Completion of laboratory testing and immunizations were similar in both groups. Adjusted mean levels for intermediate outcomes of diabetes care and the percentage achieving recommended levels varied slightly but were not statistically or clinically significant. Few differences in the quality of diabetes care were found between urban and rural Indian health sites. Differences in the receipt of dental examinations may reflect differences in resources and staffing between urban and rural settings. This study serves as a baseline for the assessment of ongoing interventions aimed at improving the quality of care.
