Preventive health care among rural American Indians in New Mexico

BACKGROUND: Incidence of and mortality from cardiovascular disease, cancer, diabetes, and other chronic diseases are rapidly increasing among American Indians; however, the utilization of preventive services for these conditions is not well characterized in these ethnic groups. METHODS: We interviewed 1,273 American Indian adults in New Mexico, ages 18 years and older, by telephone regarding routine health checks, including blood pressure, blood cholesterol, mammograms, clinical breast exams, Pap smears, influenza and pneumonia vaccinations, and diabetes using items from the CDC Behavioral Risk Factor Surveillance System. RESULTS: We found that utilization of preventive service was surprisingly high among rural American Indians. Routine health checks and blood pressure checks within the past year were reported by more than 70% of the population. Blood cholesterol checks (41.1%) and pneumonia vaccinations (30.7%) were less commonly reported. Utilization of cancer screening for the most common women's cancers was also high. Most women reported ever having a Pap smear test (88.3%), a clinical breast examination (79.5%), and a mammogram (75.6%). The prevalence of diagnosed diabetes (8.8% overall and 26.4% for ages 50 years and older) greatly exceeds the nationwide prevalence. CONCLUSIONS: The utilization of preventive services delivered by a unique governmental partnership is high among American Indians in New Mexico and, except for cholesterol screening, is comparable with rates for the U.S. population. Because cardiovascular disease is on the rise, more attention to preventive services in this arena is warranted. The high and increasing prevalence of diagnosed diabetes suggests that aggressive diabetes screening and interventions are needed.     

Do income effects mask social and behavioural factors when looking at universal health care provision?

Summary Objectives: To investigate whether permanent and transitory income effects mask the impact of unobservable factors on the uptake of health check-ups in Britain. Methods: We used a secondary data representative of the British population, the British Household Panel Survey. Outcome variables included uptake of dental health check-ups, eyesight tests, blood pressure checks, cholesterol tests, mammograms and cervical smear tests. Transitory income was measured as monthly household income and permanent income as average income over 13 years. Estimation method applied dynamic random effect probit model. Results: Results showed the absence of permanent and transitory effects on the uptake of eyesight tests, cholesterol tests, mammograms and cervical smear tests. Permanent income was associated with dental check-ups and transitory income with uptake of blood pressure tests. Conclusions: The presence of income effects on the uptake of blood pressure checks may be due to factors associated with income, such as stress or lifestyles, rather than income per se. A permanent income effect on dental health care in Britain, which is not free of charge, could indicate the possibility of economic constraints to service uptake, but it does not guarantee that income is the only factor that matters as there may important cultural and behavioural barriers.

Race, rural residence, and control of diabetes and hypertension

PURPOSE: African Americans are at increased risk for diabetes mellitus and hypertension, and rural residents have historically had decreased access to care. It is unclear whether living in a rural area and being African American confers added risks for diagnosis and control of diabetes and hypertension. The purpose of this study was to examine the prevalence of diagnosed diabetes and hypertension, as well as control of both conditions, among rural and urban African Americans and whites. METHODS: We conducted an analysis of the Third National Health and Nutrition Examination Survey (1988-1994). Non-Hispanic African Americans and non-Hispanic white adults 20 years and older were classified according to rural or urban residence (n = 11,755). Investigated outcomes were previously diagnosed diabetes mellitus and hypertension and control of diabetes and hypertension. RESULTS: The prevalence of diagnosed diabetes was 4.5% for urban whites, 6.5% for rural whites, 6.0% for urban African Americans, and 9.5% for rural African Americans. Among patients with diagnosed diabetes, 33% of rural whites, 43% of urban whites, 45% of urban African American, and 61% of rural African Americans had glycosylated hemoglobin (HbA(1c)) levels of 8% or higher (P < .01). Among patients with diagnosed hypertension, 11% of rural whites, 13% of urban whites, 20% of urban African Americans, and 23% of rural African Americans had diastolic blood pressure greater than 90 mmHg (P < .01). In regression models controlling for relevant variables, including body mass index, health status, access to care, education, income, and insurance, compared with rural African Americans, rural and urban whites were significantly more likely to have better glycemic control and diastolic blood pressure control. Urban African Americans also had better diabetes control than rural African Americans. CONCLUSIONS: In this nationally representative sample, rural African Americans are at increased risk for a lack of control of diabetes and hypertension.     

Relationship of diabetes-specific knowledge to self-management activities, ambulatory preventive care, and metabolic outcomes

BACKGROUND: Educational interventions increase diabetes patients' knowledge and self-care activities, but their impact on the use of health services to prevent diabetes complications is unclear. We sought to determine the relationship of patients' diabetes-specific knowledge with self-management behaviors, use of ambulatory preventive care, and metabolic outcomes. METHODS: We surveyed 670 adults with diabetes from three managed care plans to assess diabetes knowledge (using an eight-item scale) and self-management activities. With chart review, we assessed five processes of care--retinal and foot examinations, low-density lipoprotein cholesterol (LDL-C) testing, hemoglobin A1c (HbA1c) testing, and urine microalbumin testing--and three metabolic outcomes--HbA1c < or = 9.5%, LDL-C <130 mg/dL (3.36 mmol/L), and last blood pressure <140/90 mm Hg. RESULTS: In adjusted analyses, a one-point increase on the knowledge scale was associated with following a diabetes diet (OR 1.23, 95% CI 1.10-1.38), blood glucose self-measurement (OR 1.29, 95% CI 1.13-1.48), and regular exercise (OR 1.15, 95% CI 1.03-1.28) but not with processes of care or metabolic outcomes. CONCLUSIONS: Knowledgeable patients were more likely to perform self-management activities but not to receive recommended ambulatory care or reach metabolic outcome goals. Providing patient education about diabetes care processes should be tested as a means of increasing ambulatory care to prevent diabetes complications.     

Quality of diabetes care among low-income patients in North Carolina.

BACKGROUND: Diabetes is a leading cause of death and disability, disproportionately affecting most ethnic minority groups, people of low socioeconomic status, the elderly, and people in rural areas. Despite the availability of evidence-based clinical recommendations, barriers exist in the delivery of appropriate diabetes care. The purpose of this study is to examine the level of diabetes care among low-income populations in North Carolina. METHODS: Baseline medical record abstractions were performed (N=429) on diabetic patients at 11 agencies serving low-income populations (community health centers, free clinics, primary care clinics, and public health clinics) across the state participating in a quality-of-diabetes-care initiative. Data were collected for four process (measurement of glycosylated hemoglobin and lipids, dilated eye examination, nephropathy assessment) and two outcome (glycemic and lipid control) measures based on the Diabetes Quality Improvement Project (DQIP) and the Health Plan Employer Data and Information Set (HEDIS), and three additional indicators (blood pressure measurement and control, and lower limb assessment). Compliance rates to individual measures were calculated overall and by demographic and health characteristics. RESULTS: Diabetes care compliance rates ranged from 77.9% for blood pressure testing to 3.3% for complete foot examinations. Differences in care were observed by age, insulin use, and prevalent disease. CONCLUSIONS: This study indicates low compliance with diabetes care guidelines in underserved North Carolinians, and inconsistency of care according to some demographic and health characteristics. These results stress the need for quality improvement initiatives that enhance the level of care received by patients with diabetes, particularly those most vulnerable to diabetes and its complications.     

Quality of diabetes care in a university health center in Lebanon.

OBJECTIVE: To assess the quality of care provided to diabetic patients by family physicians in a university health clinic, using measures of glycemic and cardiovascular risk control as well as documentation of and adherence to World Health Organization (WHO) guidelines for diabetes primary care. DESIGN: Chart review of the previous year's medical notes for all identified diabetics in the practice over 2.5 years. RESULTS: Two-hundred and four diabetic patients were identified, with an estimated prevalence of 4.1%. The majority was type II diabetics, on oral hypoglycemic agents. Glycosylated hemoglobin was documented in 39.7% of patients, fasting plasma glucose in 99%, cholesterol in 93.1%, triglycerides in 91.2% and blood pressure in 85.8%; optimal control of these indicators was noted in 28.4%, 17.8%, 34%, 29.6% and 55.4% respectively. Fifty percent of the diabetics were referred for retinal checks. Physicians documented the presence of nephropathy in 46.8% and neuropathy in 59.6%; however, they documented patient instruction on foot care, diet, exercise and diabetes self-care poorly. CONCLUSION: There is a need for interventions to improve management and documentation in diabetes care in order to achieve early detection and prevention of complications. Developing a protocol for the clinic based on standard guidelines, and the use of flow sheets may be helpful in improving these intermediate indicators of quality of care.     

Outcomes of diabetes care: a population-based study.

AIMS: To describe prevalence, metabolic control, and complications of diabetes mellitus in a county in Northern Sweden, in order to improve diabetes care and guide decision makers. METHODS: A population-based, cross-sectional, retrospective study of medical records of all registered persons with diabetes mellitus (n = 5251) in the area. Assessments and examinations concerning metabolic control and complications were studied over a period of 15 months. RESULTS: Of the 5143 patients included, 13% had Type 1, 86% Type 2, and 1% other types of diabetes. An annual check-up was performed in 84% of patients. Glycosylated haemoglobin (HbA1c) was assessed in 88%, and had a mean value of 7.3% (sd 1.3%). Metabolic control was good in 33% and acceptable in another 26%. Risk factors for complications were found in 64%; in 35% body mass index was > 30; 50% had hypertension; 22% were smokers; 51% had macro- and/or microvascular complications; ischaemic heart disease 26%; a cerebrovascular lesion 13%; amputation 1.8%; proteinuria 7.9%; microalbuminuria 2.6%; peripheral neuropathy 30%; impaired peripheral circulation 29%; and retinopathy 37%. CONCLUSIONS: The majority of patients with diabetes in the study area attended an annual check-up, had acceptable metabolic control and severe complications were uncommon. Nevertheless, the number of undocumented examinations was high, 40% of the patients had unacceptable metabolic control and more than 50% had macrovascular risk factors. These findings emphasize the importance in diabetes care of smoking cessation and intensive treatment of high blood pressure.     

Management of cardiovascular risk factors in people with diabetes in primary care: cross-sectional study

OBJECTIVES: Cardiovascular disease is the major cause of morbidity and mortality in people with diabetes. The management of cardiovascular risk factors in people with diabetes in primary care was compared with National Institute of Clinical Excellence guidelines. DESIGN: A cross-sectional study in 26 general practices, with a combined list size of 256,188 patients, participating in the Kent, Surrey and Sussex Primary Care Research Network. Primary outcomes were process of care measures. METHODS: Analysis of general practice computer data on the management of 5980 patients with diabetes, of whom 86% were aged 45 years and over. RESULTS: The prevalence of diabetes was 2.0% in women and 2.6% in men, much lower than the estimated expected prevalence of 4.8% for women and 3.3% in men. Blood pressure was well recorded (96% in both sexes), cholesterol levels less well (79% of women, 84% of men). Hypertension (78% of women, 72% of men) was common. Twenty-one percent of women and 16% of men had a blood pressure above 160/100 mmHg, suggesting under use of antihypertensive therapy. Cholesterol levels were >or=5 mmol/l in 46% of women and 38% of men. Lipid-lowering drugs were prescribed in 38% of women and men. Aspirin was prescribed in 38% of women and 40% of men. CONCLUSIONS: There is an under-diagnosis of diabetes and an under-treatment of blood pressure and blood cholesterol, more marked in women than in men. There is scope for improved management within general practice, including addressing sex inequalities.     

Improvements in Care and Reduced Self-management Barriers Among Rural Patients With Diabetes

CONTEXT: Improved preventive care and clinical outcomes among patients with diabetes can reduce complications and costs; however, diabetes care continues to be suboptimal. Few studies have described effective strategies for improving care among rural populations with diabetes. PURPOSE: In 2000, the Park County Diabetes Project and the Montana Diabetes Control Program collaboratively implemented a countywide effort, which included health systems interventions and coordinated diabetes education, to improve the quality of diabetes care. METHODS: Clinical data from the diabetes registries in 2 primary care practices, in addition to baseline and follow-up telephone surveys, were used to evaluate improvements in care, outcomes, education, and barriers to self-management. FINDINGS: In the cohort of patients, the proportion receiving the following services increased significantly from 2000 to 2003: annual foot examination (43% to 58%), influenza (30% to 53%), and pneumoccocal immunizations (39% to 70%). The median hemoglobin A1c values decreased significantly from baseline to follow-up (7.2% to 6.8%). Mean systolic and diastolic blood pressure decreased significantly over the 2 time periods (139 mmHg to 135 mmHg, and 78 mmHg to 75 mmHg, respectively). Significant decreases were also observed in barriers to self-management, including lack of knowledge (decrease from 12% to 5%), difficulties making lifestyle changes (36% to 27%), cost of monitors and test strips (25% to 16%), cost of medications (37% to 24%), and diabetes education (22% to 4%). CONCLUSIONS: Findings suggest that system changes in primary care practices and the implementation of accessible diabetes education can improve care and reduce barriers for rural patients with diabetes.     

Use of diabetes preventive care and complications risk in two African-American communities

BACKGROUND: We examined levels of diabetes preventive care services and glycemic and lipid control among African Americans with diabetes in two North Carolina communities. METHODS: Cross-sectional, population-based study of 625 African-American adults with diagnosed diabetes. Participants had a household interview to determine receipt of preventive care services including glycosylated hemoglobin (HbA(1c)), blood pressure, lipid, foot, dilated eye, and dental examinations; diabetes education; and health promotion counseling. A total of 383 gave blood samples to determine HbA(1c) and lipid values. RESULTS: Annual dilated eye, foot, and lipid examinations were reported by 70% to 80% of the population, but only 46% reported HbA(1c) tests. Rates of regular physical activity (31%) and daily self-monitoring of blood glucose (40%) were low. Sixty percent of the population had an HbA(1c) level >8% and one fourth had an HbA(1c) level >10%. Half of the population had a low-density lipoprotein value >130 mg/dL. Lack of insurance was the most consistent correlate of inadequate care (odds ratio [OR]=2.3; 95% confidence interval [CI]=1.3-3.9), having HbA(1c) >9.5% (OR=2.1, 95% CI=1.1-4.2), and LDL levels >130 mg/dL (OR=2.1; 95% CI=1.0-4.5). CONCLUSIONS: Levels of diabetes preventive care services were comparable to U.S. estimates, but glycemic and lipid control and levels of self-management behaviors were poor. These findings indicate a need to understand barriers to achieving and implementing good glycemic and lipid control among African Americans with diabetes.     

Quality of diabetes care among patients managed by teleconsultation

We studied a new teamwork-based teleconsultation model for treating patients with diabetes, where a specialist in diabetes care, a diabetes nurse and a patient attended by videoconference. The study series consisted of all the patients (n = 101) at three health centres in northern Finland whose care was provided by a single physician at a remote diabetes clinic. A total of 101 patients with diabetes (19 of type 1 and 82 of type 2) were studied at baseline and at 10-14 months after the first consultation. Mean HbA(1c) was 8.0% at baseline and 7.6% at follow-up (P = 0.007). The proportion of patients with poor glycaemic control decreased from 32% to 13%. Mean LDL cholesterol was 3.3 mmol/L at baseline and 2.7 mmol/L at follow-up (P < 0.001). The percentage of patients with optimum lipid levels increased from 20% to 50%. Mean systolic blood pressure was 146 mmHg at baseline and had decreased by 6 mmHg at follow-up (P = 0.004). The percentage of patients with poor blood pressure control decreased from 19% to 8%. The most common changes in medication were the introduction or modification of insulin treatment and the introduction of statin and antihypertensive drugs and acetylsalicylic acid. Although the study was uncontrolled, there were improvements in glucose and LDL cholesterol levels and blood pressure in patients who were managed by teleconsultation.     

Electronic Patient Registries Improve Diabetes Care and Clinical Outcomes in Rural Community Health Centers

ABSTRACT:  Context: Diabetes care is challenging in rural areas. Research has shown that the utilization of electronic patient registries improves care; however, improvements generally have been described in combination with other ongoing interventions. The level of basic registry utilization sufficient for positive change is unknown. Purpose: The goal of the current study was to examine differential effects of basic registry utilization on diabetes care processes and clinical outcomes according to level of registry use in a rural setting. Methods: Patients with diabetes (N = 661) from 6 Federally Qualified Health Centers in rural West Virginia were entered into an electronic patient registry. Data from pre- and post-registry were compared among 3 treatment and control groups that had different levels of registry utilization: low, medium, or high (for example, variations in the use of registry-generated progress notes examined at the point-of-care and in the accuracy of registry-generated summary reports to track patients' care). Data included care processes (annual exams, screens to promote wellness, education, and self-management goal-setting) and clinical outcomes (HbA1c, LDL, HDL, cholesterol, triglycerides, blood pressure). Findings: The registry assisted in significantly improving 12 of 13 care processes and 3 of 6 clinical outcomes (HbA1c, LDL, cholesterol) for patients exposed to at least medium levels of registry utilization, but not for the controls. For example, the percent of patients who had received an annual eye exam at follow-up was 11%, 34%, and 38% for the low, medium, and high utilization groups, respectively; only the latter groups improved. Conclusions: As an initial step to achieving control of diabetes, basic registry utilization may be sufficient to drive improvements in provider-patient care processes and in patient outcomes in rural clinics with few resources.     

Associations between technical quality of diabetes care and patient experience

Aims It has long been held that high‐quality care has both technical and interpersonal aspects. The nature and strength of any association between both aspects remain poorly explored. This study investigated the associations between diabetes patients’ reports of receiving recommended care (as measures of technical quality) and their experience and ratings (as measures of interpersonal care). Methods Using data from a cross section of 3096 patients with diabetes nested within 24 diabetes‐care‐networks, we conducted multilevel regression analysis of the relationships between nine indicators of receiving care recommended in practice guidelines and: six scales of patient experience and global ratings of general practitioner, nurses, and overall diabetes care. Results On average, reporting having received recommended care was associated with reporting better patient experience and ratings. The extent and frequencies of these associations varied across the different care processes. Receiving foot examination, physical activity advice, smoking status check, eye examination, and HbA_1c testing, but not nutritional advice, urine, cholesterol or blood pressure checks, were statistically associated with better patient experience and global ratings. Those who received HbA_1c testing rated their overall care 1.002 points higher (95% confidence interval: 0.726–1.278) on a scale of 0–10 than those who did not. Conclusions Higher self‐reported technical quality of care in diabetes appears to be frequently but not always associated with better experiences and ratings. It is possible that the former leads to the latter and/or that both share a common cause within providers. Both care aspects do not seem interchangeable during performance assessment.     

Socio-economic status, ethnicity and diabetes management: an analysis of time trends using the health survey for England

BACKGROUND: The National Health Service (NHS) has invested substantially in recent years to reduce variations in health care for chronic conditions such as diabetes. We examined trends in the management of diabetes in England between socio-economic and ethnic groups from 1998 to 2004. METHODS: Secondary analyses of Health Survey for England data comparing achievement of national treatment target for blood glucose, blood pressure and cholesterol and use of medications in survey respondents with diabetes. RESULTS: The proportion of respondents with diabetes achieving national treatment targets increased significantly between 1998 and 2004. There was a significantly lower increase in blood pressure control in the black group [13.9% (95% confidence interval (CI) 13.0-14.8%)] but higher increase in south Asian and white Irish groups when compared to the white British group [15.7% (95% CI 15.4-16.0%)]. Manual workers experienced lower improvements in blood pressure control [15.3% (95% CI 14.9-15.7%) versus 16.7% (95% CI 16.2-17.2%)] but higher improvements in cholesterol control [10.3% (95% CI 9.7-10.9%) versus 7.4% (95% CI 6.8-8.0%)] when compared to non-manual workers. CONCLUSION: There were considerable improvements in the management of diabetes in England during a period of sustained investment in health care quality but these were not distributed uniformly across ethnic and socio-economic groups.

目的:了解我国农村地区产前保健状况,探讨存在的问题。方法:利用联合国儿童基金会与中国卫生部目前在中国13个省50个县进行的"母子系统保健项目"的基线调查资料进行描述性分析和分层描述。结果:5岁以下儿童母亲和孕中晚期孕妇产前检查率分别为82.9%和88.9%;孕早期检查率分别为45.9%和50.0%;首次产前检查地点均以乡卫生院为主;产前检查次数分布为产前检查率较高,而至少4次检查率低、按时检查率低;5个基础项目全部检查率分别为17.6%和16.5%。四类农村地区之间,产前保健各项指标均随经济水平下降而下降。结论:被调查农村地区产前保健服务存在一定的质量问题,且四类地区间发展不平衡,应大力提高产前保健服务质量。     

Impact of electronic health record clinical decision support on diabetes care: a randomized trial

PURPOSE We wanted to assess the impact of an electronic health record–based diabetes clinical decision support system on control of hemoglobin A_1c (glycated hemoglobin), blood pressure, and low-density lipoprotein (LDL) cholesterol levels in adults with diabetes.METHODS We conducted a clinic-randomized trial conducted from October 2006 to May 2007 in Minnesota. Included were 11 clinics with 41 consenting primary care physicians and the physicians’ 2,556 patients with diabetes. Patients were randomized either to receive or not to receive an electronic health record (EHR)–based clinical decision support system designed to improve care for those patients whose hemoglobin A_1c, blood pressure, or LDL cholesterol levels were higher than goal at any office visit. Analysis used general and generalized linear mixed models with repeated time measurements to accommodate the nested data structure.RESULTS The intervention group physicians used the EHR-based decision support system at 62.6% of all office visits made by adults with diabetes. The intervention group diabetes patients had significantly better hemoglobin A_1c (intervention effect −0.26%; 95% confidence interval, −0.06% to −0.47%; P=.01), and better maintenance of systolic blood pressure control (80.2% vs 75.1%, P=.03) and borderline better maintenance of diastolic blood pressure control (85.6% vs 81.7%, P =.07), but not improved low-density lipoprotein cholesterol levels (P = .62) than patients of physicians randomized to the control arm of the study. Among intervention group physicians, 94% were satisfied or very satisfied with the intervention, and moderate use of the support system persisted for more than 1 year after feedback and incentives to encourage its use were discontinued.CONCLUSIONS EHR-based diabetes clinical decision support significantly improved glucose control and some aspects of blood pressure control in adults with type 2 diabetes.     

Implementation of diabetes prevention programs in rural areas: Montana and south-eastern Australia compared

Objective: To identify the key elements that enabled the Greater Green Triangle Diabetes Prevention Project (GGT DPP) and the Montana Cardiovascular Disease and Diabetes Prevention (CDDP) programs successful establishment and implementation in rural areas, as well as identifying specific challenges or barriers for implementation in rural communities. Methods: Focus groups were held with the facilitators who delivered the GGT DPP in Australia and the Montana CDDP programs in the USA. Interview questions covered the facilitators' experiences with recruitment, establishing the program, the components and influence of rurality on the program, barriers and challenges to delivering the program, attributes of successful participants, and the influence of community resources and partnerships on the programs. Results: Four main themes emerged from the focus groups: establishing and implementing the diabetes prevention program in the community; strategies for recruitment and retention of participants; what works in lifestyle intervention programs; and rural‐centred issues. Conclusions: The results from this study have assisted in determining the factors that contribute to developing, establishing and implementing successful diabetes prevention programs in two rural areas. Recommendations to increase the likelihood of success of programs in rural communities include: securing funding early for the program; establishing support from community leaders and developing positive relationships with health care providers; creating a professional team with passion for the program; encouraging participants to celebrate their small and big successes; and developing procedures for providing post‐intervention support to help participants maintain their success.     

Management of cardiovascular risk in the usual care of Medicaid recipients

Uncontrolled risk factors contribute substantially to cardiovascular disease burden. With retrospective chart review, we examined rates of cardiovascular risk factor assessment and intervention during the course of usual care for a representative sample of 3,742 adult North Carolina Medicaid recipients with diagnosed hypertension managed by a primary care provider. Most patients had been established with their provider for at least three years. Ninety-six percent had multiple modifiable risk factors. Blood pressure and cholesterol were above goal for 52.9% and 37.2% of patients, respectively. Among those with uncontrolled blood pressure, only 44.3% had intensification of therapy within the prior year. Half of patients with cholesterol above goal were treated with medication; and half of current smokers had documented advice to quit. Documentation of aspirin use or counseling was rare. Despite Medicaid coverage and access to care, many effective strategies to prevent cardiovascular events were underutilized, even among patients at highest risk.
