Achievable benchmarks of care for primary care quality indicators in a practice-based research network.

A number of sources publish health care quality reports in the United States, but there is limited information about achievable performance in primary care settings. The objective of this article is to report Achievable Benchmarks of Care (ABCs) for 54 quality indicators. Eighty-seven practices participating in a demonstration project in the Practice Partner Research Network (PPRNet), representing 35 US states and 711 969 patients, were included in the analyses. PPRNet practices use a common electronic medical record (Practice Partner, Seattle, Washington). ABCs ranged from 25% to 99%. High ABCs (> or =90%) were achieved for blood pressure screening, lipid screening, and avoiding antibiotics in upper respiratory infection. Some calculated ABCs may be lower than the actual ABCs due to incomplete data recording or abstracting. Primary care practices can achieve high performance across a number of quality indicators, and PPRNet ABCs can serve as benchmarks for primary care practitioners and payers.

Long-term prognostic value of resting heart rate in subjects with prehypertension.

BACKGROUND: Increased resting heart rate increases cardiovascular risk in individuals with hypertension. The extent to which such risk extends to people with prehypertension is not known. The purpose of this study was to determine whether elevated resting heart rate contributes to increased coronary heart disease (CHD) risk in people with prehypertension. METHODS: The cohort for the current study consisted of 3275 persons from the Atherosclerosis Risk in Communities (ARIC) study, 45 to 64 years old in 1986 to 1989, with a mean follow-up of 10.1 years. The primary outcomes were CHD and all-cause mortality. RESULTS: Individuals with prehypertension and elevated resting heart rate had 50% higher all-cause mortality than people with prehypertension and lower resting heart rate (hazard ratio [HR] 1.50, 95% confidence interval [CI] 1.0-2.15), which was essentially unchanged after controlling for age, ethnicity, gender, diabetes, smoking status, LDL-cholesterol, exercise, and use of antilipemic agents (P < .01). Similarly, in unadjusted analyses, CHD risk was 49% higher for people with increased heart rate (HR 1.49, 95% CI 1.03-2.14). In adjusted analyses, elevated resting heart rate remained a factor in increased risk of CHD in women (adjusted HR 2.18, 95% CI 1.08-4.42), but not in men. CONCLUSIONS: Resting heart rate is an easily accessible tool that may be helpful for stratifying CHD and mortality risk in people with prehypertension.

Evidence of nephropathy and peripheral neuropathy in US adults with undiagnosed diabetes.

PURPOSE: Nearly one third of diabetes cases in the United States is undiagnosed, with mounting evidence that complications accrue even before clinical diagnosis. We wanted to determine whether persons with undiagnosed diabetes have signs of nephropathy and peripheral neuropathy. METHODS: We examined the prevalence of positive screening tests for nephropathy and peripheral neuropathy in adults aged > or = 40 years with undiagnosed diabetes using secondary analysis of survey and examination data from the population-based United States National Health and Nutrition Examination Survey 1999-2002. We defined a positive screening test for nephropathy as a spot urine albumin-creatinine ratio > 30.0 mg/g, representing at least microalbuminuria. We defined > or = 1 insensate area on Semmes-Weinstein monofilament testing as a positive finding for neuropathy. Undiagnosed diabetes was defined as a combination of no history of diagnosed diabetes and a measured fasting glucose > or = 126 mg/dL. We used SUDAAN for chi2 and regression analyses. RESULTS: The prevalence of a positive test when screening for nephropathy among those with undiagnosed diabetes was 26.5% compared with 7.1% in those with no diabetes (chi2, P <.01). After adjusting for age and diagnosed or undiagnosed hypertension, the association of undiagnosed diabetes with nephropathy persisted (odds ratio = 2.35; 95% confidence interval, 1.38-4.01). For peripheral neuropathy, 21.5% with undiagnosed diabetes had positive screening tests compared with 10.1% with no diabetes (chi2, P <.01); however, this effect was not significant after adjustment for age. There was no significant difference in positive screening tests for nephropathy or neuropathy when comparing those with undiagnosed and diagnosed diabetes. CONCLUSIONS: A significant proportion of adults with undiagnosed diabetes have signs of nephropathy and peripheral neuropathy. These findings may influence policies about early screening for diabetes.

The logic behind a multimethod intervention to improve adherence to clinical practice guidelines in a nationwide network of primary care practices.

The gap between evidence-based guidelines for clinical care and their application in medical settings is well established and widely discussed. Effective interventions are needed to help health care providers reduce this gap. Whereas the development of clinical practice guidelines from biomedical and clinical research is an example of Type 1 translation, Type 2 translation involves successful implementation of guidelines in clinical practice. This article describes a multimethod intervention that is part of a Type 2 translation project aimed at increasing adherence to clinical practice guidelines in a nationwide network of primary care practices that use a common electronic medical record (EMR). Practice performance reports, site visits, and network meetings are intervention methods designed to stimulate improvement in practices by addressing personal and organizational factors. Theories and evidence supporting these interventions are described and could prove useful to others trying to translate medical research into practice. Additional theory development is needed to support translation in medical offices.

Prehypertension and cardiovascular morbidity.

PURPOSE: The Seventh Report of the Joint National Commission (JNC 7) on High Blood Pressure established prehypertension (120 to 139 mm Hg systolic or 80 to 89 mm Hg diastolic) as a new risk category. We aim to determine the risk of major cardiovascular events associated with blood pressure in the prehypertensive range in a longitudinal, population-based cohort. METHODS: Analyses were conducted on participants in the National Health and Nutrition Examination Survey I (1971-1975) observed for 18 years for major cardiovascular disease events. Cox proportional hazard ratios were calculated to assess relative risk of cardiovascular disease, including stroke, myocardial infarction, and heart failure, in participants with prehypertension and normal blood pressure (<120/80 mm Hg). RESULTS: Prehypertension was associated with increased risk for cardiovascular disease (1.79 [95% confidence interval (CI) 1.40-2.24]) in unadjusted analysis. After adjustment for cardiovascular risk factors, the relationship of prehypertension to cardiovascular disease was diminished but persisted (1.32 [95% CI 1.05-1.65]). Ninety-three percent of prehypertensive individuals had at least 1 cardiovascular risk factor. Low prehypertension (120-129/80-84 mm Hg) was associated with increased cardiovascular disease in unadjusted analyses (1.56 [95% CI 1.23-1.98]) but was not statistically significant in adjusted analyses (1.24 [95% CI 0.96-1.59]). High-normal blood pressure (130-139/85-89 mm Hg) remained a predictor of cardiovascular disease in unadjusted (2.13 [95% CI 1.64-2.76]) and adjusted (1.42 [95% CI 1.09-1.84]) analyses. CONCLUSIONS: In a longitudinal, population-based, US cohort, prehypertension was associated with increased risk of major cardiovascular events independently of other cardiovascular risk factors. These findings, along with the presence of cardiovascular risk factors in the majority of participant sample with prehypertension, support recommendations for physicians to actively target lifestyle modifications and multiple risk reduction in their prehypertensive patients.

Prehypertension and mortality in a nationally representative cohort.

The Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure 7 recommendations include early identification of prehypertension (120 to 139 mm Hg systolic or 80 to 89 mm Hg diastolic). Although prehypertension is a risk factor for hypertension, little is known of prehypertension's independent risk for mortality. We conducted an analysis of a nationally representative cohort in the second National Health and Nutrition Examination Survey 1976 to 1980 (NHANES II) and the NHANES II Mortality Study, 1992. The cohort included 9,087 patients aged 30 to 74 years at baseline, who represented nearly 95 million Americans. Cox proportional-hazards models were conducted for both cardiovascular disease (CVD) and all-cause mortality. The unadjusted relative risk of both all-cause (hazard ratio [HR] 1.27, 95% confidence interval [CI] 1.02 to 1.58) and CVD (HR 1.66, 95% CI 1.21 to 2.26) mortality is increased for patients with prehypertension over patients with normal blood pressure (BP). Almost all patients with hypertension (93%), prehypertension (90%), and normal BP (85%) have other CVD risk factors. When the presence of any CVD risk factor is adjusted for in the survival analysis, the adjusted relative risk of both all-cause (HR 0.82, 95% CI 0.64 to 1.04) and CVD (HR 1.00, 95% CI 0.72 to 1.39) mortality is no longer increased for patients with prehypertension. Similarly, in analyses of patients aged >/=55 years, there is no significant independent mortality risk for prehypertension. Lifestyle interventions targeting multiple risk factors including BP may be the most effective prevention strategy.

Strategies to accelerate translation of research into primary care within practices using electronic medical records.

This research describes implementation strategies used by primary care practices using electronic medical records in a national quality improvement demonstration project, Accelerating Translation of Research into Practice, conducted within the Practice Partner Research Network. Qualitative methods enabled identification of strategies to improve 36 quality indicators. Quantitative survey results provide mean scores reflecting the integration of these strategies by practices. Nursing staff plays important roles to facilitate quality improvement within collaborative primary care practices.

Virtual medical care: how are our patients using online health information?

An increasing percentage of Internet users are seeking health information online. The purpose of our study was to determine the extent of Internet access and online health-seeking and the feasibility of implementing Internet services for our urban, residency-based practice. Using a self-administered survey, we obtained information on use of the Internet, demographics and socioeconomic profile, presence of a chronic medical condition and self-rated health from 300 consecutive patients. Complete surveys were obtained by 203 (68 percent). Responses were compared based on demographic, socioeconomic, and medical variables using Chi-square analysis. Results showed that our sample population tended to be under age 50, female, non-Hispanic Black, low income, and healthy. Seventy-seven percent of respondents had accessed the Internet at least once, 79 percent had used the Internet to find health-related information, 73 percent used the online information to make a health-related decision, 50 percent shared the information with their provider. In conclusion, we confirmed a high rate of Internet usage in our specific patient population, characterized by low socioeconomic status, low education level, and high minority percentages. Our patients not only access online health information, but also make changes based on this information, with only about half of all patients sharing this information with their physicians. It is unclear how this system of 'virtual medical care' influences overall patient health.

Initial steps taken by nine primary care practices to implement alcohol screening guidelines with hypertensive patients: the AA-TRIP project.

Many medical conditions are caused or exacerbated by heavy drinking, necessitating alcohol screening and discussion in primary care practices. This is particularly true of hypertension, the most common primary diagnosis in the United States, which has been linked to the regular consumption of 3 or more standard alcoholic beverages a day. The Accelerating Alcohol Screening-Translating Research into Practice (AA-TRIP) project was designed to improve detection and management of alcohol problems in primary care patients with hypertension. Medical providers are being trained using the Practice Partner Research Network's- Translating Research into Practice (PPRNet-TRIP) quality improvement model. This includes a multi-method intervention (electronic medical records, on-site academic detailing, practice feedback reports and annual network meetings) to help practices increase adherence to clinical guidelines. Qualitative analyses of initial steps taken by nine primary care practices toward the routine implementation of alcohol screening guidelines are presented. Organizational factors and provider and patient characteristics all influenced the method and consistency of alcohol screening and intervention. Perceived time constraints, patient sensitivity to questions about alcohol, and possible stigma associated with a diagnosis of alcoholism were also relevant barriers requiring problem solving.

How to guide patients for online information: focus on chronic disease.

The purpose of this study was to evaluate the accessibility and utility of a common Internet search strategy so physicians might provide this guidance to their patients seeking health information on chronic disease. We selected three common chronic diseases: diabetes, hypertension, and osteoarthritis. We then formulated basic questions from a patient perspective about diagnosis, treatment, and prognosis. A non-medical professional attempted to answer these questions by typing the disease name into the Google search engine. Focusing on the first ten web sites on the Google list was a successful strategy for finding sites that could answer the study questions (average of 61% of the time). The average number of clicks required to answer any question was 1.6. Web sites sponsored by government agencies (89% success) and hospitals (100% success) yielded answers to the questions more often than other sites. In conclusion, despite the multitude of web sites that appear when the name of a chronic disease is entered into a search engine, the top ten results are usually adequate to provide relevant information on common clinical questions to the average patient. Physicians can guide patients to relevant information by instructing them to type the name of the disease itself into a search engine and focusing on government and hospital-sponsored Web sites.
