Randomized controlled trial of the effects of nurse case manager and community health worker interventions on risk factors for diabetes-related complications in urban African Americans

BACKGROUND African Americans suffer disproportionately from diabetes complications, but little research has focused on how to improve diabetic control in this population. There are also few or no data on a combined primary care and community-based intervention approach. METHODS We randomly assigned 186 urban African Americans with type 2 diabetes (76% female, mean A SD age 59 A 9 years) to 1 of 4 parallel arms: (1) usual care only; (2) usual care + nurse case manager (NCM); (3) usual care + community health worker (CHW); (4) usual care + nurse case manager/community health worker team. Using the framework of the Precede-Proceed behavioral model, interventions included patient counseling regarding self-care practices and physician reminders. RESULTS The 2-year follow-up visit was completed by 149 individuals (84%). Compared to the Usual care group, the NCM group and the CHW group had modest declines in HbA(1c) over 2 years (0.3 and 0.3%, respectively), and the combined NCM/CHW group had a greater decline in HbA(1c) (0.8%. P = 0.137). After adjustment for baseline differences and/or follow-up time, the combined NCM/CHW group showed improvements in triglycerides (-35.5 mg/dl; P = 0.041) and diastolic blood pressure, compared to the usual care group (-5.6 mmHg; P = 0.042). CONCLUSIONS Combined NCM/CHW interventions may improve diabetic control in urban African Americans with type 2 diabetes. Although results were clinically important, they did not reach statistical significance. This approach deserves further attention as a means to reduce the excess risk of diabetic complications in African Americans.

The Effects of a Nurse Case Manager and a Community Health Worker Team on Diabetic Control, Emergency Department Visits, and Hospitalizations Among Urban African Americans With Type 2 Diabetes Mellitus: A Randomized Controlled Trial

BACKGROUND Although African American adults bear a disproportionate burden from diabetes mellitus (DM), few randomized controlled trials have tested culturally appropriate interventions to improve DM care. METHODS We randomly assigned 542 African Americans with type 2 DM enrolled in an urban managed care organization to either an intensive or minimal intervention group. The intensive intervention group consisted of all components of the minimal intervention plus individualized, culturally tailored care provided by a nurse case manager (NCM) and a community health worker (CHW), using evidence-based clinical algorithms with feedback to primary care providers (eg, physicians, nurse practitioners, or physician assistants). The minimal intervention consisted of mailings and telephone calls every 6 months to remind participants about preventive screenings. Data on diabetic control were collected at baseline and at 24 months by blind observers; data emergency department (ER) visits and hospitalizations were assessed using administrative data. RESULTS At baseline, participants had a mean age of 58 years, 73% were women, and 50% were living in poverty. At 24 months, compared with the minimal intervention group, those in the intensive intervention group were 23% less likely to have ER visits (rate difference [RD], -14.5; adjusted rate ratio [RR], 0.77; 95% confidence interval [CI], 0.59-1.00). In on-treatment analyses, the rate reduction was strongest for patients who received the most NCM and CHW visits (RD, -31.0; adjusted RR, 0.66; 95% CI, 0.43-1.00; rate reduction downward arrow 34%). CONCLUSION These data suggest that a culturally tailored intervention conducted by an NCM/CHW team reduced ER visits in urban African Americans with type 2 DM.

Racial Comparisons of Health Care and Glycemic Control for African American and White Diabetic Adults in an Urban Managed Care Organization

The excess risk of diabetic complications in African Americans may be due to poor glycemic control arising from suboptimal use and/or quality of diabetes-related health care. However, little is known about racial differences in these factors, particularly in urban populations. We conducted a cross-sectional study using medical claims and encounter data on 1,106 adults with diabetes aged > or =30 years who were members of an urban managed care organization in capitated health plans. We examined health care and routine hemoglobin A(1c) (HbA(1c)) testing in a biracial cohort for 12 months. We then followed individuals for an additional 12 months, using a retrospective cohort design, to determine how this health care predicted subsequent emergency room visits. On average, compared with their white counterparts, African Americans had fewer primary care visits (85% vs. 91% with four or more visits) and fewer HbA(1c) tests (56% vs. 68% with two or more HbA(1c) tests) (all P < 0.05). Likewise, in the subset who underwent one or more HbA(1c) measurement (n = 855), African Americans displayed poorer glycemic control (HbA(1c) 9.1 +/- 2.9%) than whites (8.5 +/- 2.2%; P = 0.001). In multivariate analyses, racial differences in visit frequency and HbA(1c) testing were attenuated by adjustment for age, sex, and type of capitated plan and did not remain statistically significant. The relationship of health care to subsequent emergency room visits differed by race; in African Americans, fewer primary care visits and HbA(1c) tests predicted greater risk of emergency room visits. Even in a capitated, managed care setting, urban African Americans with diabetes are less likely than their white counterparts to undergo routine primary care visits and laboratory testing and are more likely to have suboptimal glycemic control. Differences in age, sex, and insurance type seemed to explain some of the disparities. Future research should determine the individual contributions of physician, patient, and system factors to the racial disparities in health care.

Factors Associated With Intensification of Oral Diabetes Medications in Primary Care Provider-Patient Dyads: A Cohort Study

OBJECTIVE—Although suboptimal glycemic control is known to be common in diabetic adults, few studies have evaluated factors at the level of the physician-patient encounter. Our objective was to identify novel visit-based factors associated with intensification of oral diabetes medications in diabetic adults. RESEARCH DESIGN AND METHODS—We conducted a nonconcurrent prospective cohort study of 121 patients with type 2 diabetes and hyperglycemia (A1C ≥8%) enrolled in an academically affiliated managed-care program. Over a 24-month interval (1999–2001), we identified 574 hyperglycemic visits. We measured treatment intensification and factors associated with intensification at each visit. RESULTS—Provider-patient dyads intensified oral diabetes treatment in only 128 (22%) of 574 hyperglycemic visits. As expected, worse glycemia was an important predictor of intensification. Treatment was more likely to be intensified for patients with visits that were “routine” (odds ratio [OR] 2.55 [95% CI 1.49–4.38]), for patients taking two or more oral diabetes drugs (2.82 [1.74–4.56]), or for patients with longer intervals between visits (OR per 30 days 1.05 [1.00–1.10]). In contrast, patients with less recent A1C measurements (OR >30 days before the visit 0.53 [0.34–0.85]), patients with a higher number of prior visits (OR per prior visit 0.94 [0.88–1.00]), and African American patients (0.59 [0.35–1.00]) were less likely to have treatment intensified. CONCLUSIONS—Failure to intensify oral diabetes treatment is common in diabetes care. Quality improvement measures in type 2 diabetes should focus on overcoming inertia, improving continuity of care, and reducing racial disparities.

Urban health and primary care at Johns Hopkins: urban primary care medical home resident training programs.

Johns Hopkins University recently implemented two novel urban health residency training programs (UHR). The programs include increased access programs, community health worker-delivered care, substance abuse screening and treatment, community psychiatry/ mental health programs, case and disease management teams, and interprofessional training. These programs are designed to create well-trained physicians who competently provide care for the underserved inner-city patient.

Perceptions of Health System Orientation Quality, Patient Centeredness, and Cultural Competency

As part of a pragmatic trial to reduce hypertension disparities, we conducted a baseline organizational assessment to identify aspects of organizational functioning that could affect the success of our interventions. Through qualitative interviewing and the administration of two surveys, we gathered data about health care personnel’s perceptions of their organization’s orientations toward quality, patient centeredness, and cultural competency. We found that personnel perceived strong orientations toward quality and patient centeredness. The prevalence of these attitudes was significantly higher for these areas than for cultural competency and varied by occupational role and race. Larger percentages of survey respondents perceived barriers to addressing disparities than barriers to improving safety and quality. Health care managers and policy makers should consider how we have built strong quality orientations and apply those lessons to cultural competency.

Implementation of a training and structured skills assessment program for medical assistants in a primary care setting.

&NA; As part of ongoing efforts to improve quality of care through clinical education of our medical assisting staff, we developed a competency‐based training and assessment program. At the time of program implementation, we assessed clinical skills of 111 certified medical assistants and found that 10% were unable to accurately measure blood pressure, 9% were unable to correctly perform an intradermal injection, and 48% were unable to correctly draw specified volumes into syringes. More than 10 years after program implementation, we continue to detect and remediate clinical skills in newly hired employees. This case study report describes the evolution of the program and assessment findings.

The Relationship Between Safety Culture and Voluntary Event Reporting in a Large Regional Ambulatory Care Group

Objectives The safety culture in the workplace may affect event reporting. We evaluated the relationship of safety culture and voluntary event reporting within a large network of ambulatory practices, most of which provided primary care. Methods This study was an observational, retrospective cohort study. Patient safety event reporting rates for 35 ambulatory practices were collected using a standard tool (UHC Patient Safety Net [PSN]) and normalized based on the number of patient visits in each practice. The overall and domain-specific safety culture of each practice was measured with a validated instrument (Safety Attitudes Questionnaire [SAQ]), distributed to 828 employees in 2013. We compared safety culture scores and the average event reporting rates during a 4-month window before and after the survey distribution. Poisson regression analyses were performed to determine the relationship between PSN reporting rates and SAQ results. Results The SAQ response rate was 87%. Practices varied widely in rates of reporting events, from 0.00 to 6.99 reports per 1000 total patient visits per month. Regression analyses indicated a positive association between PSN reporting rates and SAQ scores for the domains of overall culture (incidence rate ratio [IRR], 1.019; P = 0.004) and 4 safety culture domains: teamwork climate (IRR, 1.016; P = 0.019), safety climate (IRR, 1.018; P = 0.004), working conditions (IRR, 1.017; P = 0.006), and perceptions of local management (IRR, 1.016; P = 0.040). Conclusions Our work provides new evidence to show that in the ambulatory setting more events and near misses are reported when there is a strong culture of safety.

Fostering Clinical Excellence Across an Academic Health System.

Objectives Changes in the US healthcare economic system are requiring academic health centers (AHCs) to restructure in pursuit of their traditional tripartite missions; engaging the individuals focused on clinical care is becoming more important. We conducted this study to guide our institution’s transformation by identifying ways to formally recognize clinicians who are excelling in patient care and understand which forms of acknowledgment would be acceptable and motivating. Methods A survey was developed by a large committee with representation spanning the AHC and was sent electronically in spring 2014 to stakeholders across the institution. Items assessed perceptions of the importance and present state of valuing clinical excellence, the utility of 14 potential metrics to assess clinical excellence, and the meaningfulness of seven potential rewards for clinical excellence. Bivariate and multivariate logistic regression models analyzed differences (P < 0.05) by respondent sex, ethnicity, academic rank, primary clinical affiliation, and time spent in patient care and research activities. Results A total of 1716 of 3168 (54%) stakeholders responded, including 1198 of 2151 (56%) individuals from academic hospitals, 114 of 276 (41%) from the outpatient affiliated practices, and 304 of 741 (54%) from satellite locations. Nearly everyone (96%) agreed that clinical accomplishments should be recognized, although a minority (47%) believed that clinicians were already valued. Most respondents selected 7 or more of 14 metrics as valid and reasonable for assessing clinical excellence. Popular metrics (eg, clinical productivity) were not believed to represent clinical excellence as much as others (eg, professionalism). Multivariate analysis found the least agreement among stakeholders on using published scholarship as evidence for clinical excellence, with the widest differences comparing senior faculty versus nonfaculty (88% vs 27%) and those with >75% of their time spent in patient care versus others (37% vs 73%). Most (six of seven) types of reward were perceived as meaningful by the majority of respondents, with little variation among subgroups across bivariate and multivariate analyses. Conclusions This system-wide assessment was successful at identifying new strategies for recognizing clinical excellence. Other AHCs seeking institutional transformation may wish to perform a similar assessment.

Design and implementation of a longitudinal ambulatory clerkship in the first-year curriculum at the Johns Hopkins School of Medicine

Abstract In response to calls for medical education reform we designed and implemented a new Longitudinal Ambulatory Clerkship (LAC) at the Johns Hopkins University School of Medicine. The LAC provides first-year medical students with their initial exposure to clinical medicine during a 12-month experience consisting of weekly clinic sessions with a practicing physician-mentor (preceptor) and longitudinal experience with a population of patients. The LAC allows students to experience firsthand many of the personal, professional, and organizational issues that impact the practice of medicine. This paper reviews the rationale, development, and challenges during implementation of this clerkship.
