Nurse consultation support to primary care practices to increase delivery of health behavior services.

Tobacco use, lack of physical activity, poor diet, and alcohol use are the key preventable causes of death in the United States. This study tested the use of nurses as consultants to primary care practices to assist practice clinicians and staff in identifying and carrying out plans to help their adult patients improve these health behaviors. A pre-post chart audit was conducted, and 17 of 20 practices (85%, p = <.01) increased documentation of health behavior delivery a mean absolute increase of 5.5% after the intervention. Nurse consultation may be an effective strategy to increase health behavior delivery to patients in primary care.

The community health educator referral liaison (CHERL): a primary care practice role for promoting healthy behaviors.

BACKGROUND: Tobacco use, unhealthy diet, physical inactivity, and risky alcohol use are leading causes of preventable death. As there are many barriers that prevent primary care clinicians from effectively assisting patients with these behaviors, connecting patients with health behavior resources may reduce these unhealthy behaviors. METHODS: A new adjunct role in primary care practice, the community health educator referral liaison (CHERL), was tested in 15 practices in three Michigan communities. All practices were advised how to access this liaison, and nine practices were randomly selected to receive support to develop a systematic referral process. Adult patients needing improvement in at least one of the four unhealthy behaviors were eligible for referral. The CHERL contacted referred patients by telephone; assessed health risks; provided health behavior-change counseling, referral to other resources, or both; and sent patient progress reports to referring clinicians. Data were collected from February 2006 through July 2007. RESULTS: The CHERLs received 797 referrals over 8 months, a referral rate of 0%-2% per practice. Among referred patients, 55% enrolled, and 61% of those participated in multiple-session telephone counseling; 85% were referred to additional resources. Among patients enrolling, improvements (p<0.001) were reported at 6 months for BMI, dietary patterns, alcohol use, tobacco use, health status, and days of limited activity in the past month. CONCLUSIONS: The results of this study suggest that through relationships with practices, patients, and community resources, these liaisons successfully facilitated patients' behavior change. The CHERL role may fill a gap in promoting healthy behaviors in primary care practices and merits further exploration.

Diagnosis of heart failure in adults.

Heart failure is a common, progressive, complex clinical syndrome with high morbidity and mortality. Coronary artery disease is its most common cause. The evaluation of symptomatic patients with suspected heart failure is directed at confirming the diagnosis, determining the cause, identifying concomitant illnesses, establishing the severity of heart failure, and guiding therapy. The initial evaluation should include a focused history and physical examination, a chest radiograph, and an electrocardiogram. The presence of heart failure can be confirmed by an echocardiogram. Heart failure is highly unlikely in the absence of dyspnea and an abnormal chest radiograph or electrocardiogram. Radionuclide angiography or contrast cineangiography may be necessary when clinical suspicion for heart failure is high and the echocardiogram is equivocal. Patients with confirmed heart failure should undergo additional testing, including a more detailed history and physical examination; a complete blood count; blood glucose measurement; liver function tests; serum electrolyte, blood urea nitrogen, and creatinine measurements; lipid panel; urinalysis; and thyroid-stimulating hormone level. A serum ferritin level, human immunodeficiency virus test, antinuclear antibody assays, rheumatoid factor test, or metanephrine measurements may be required in selected patients. Patients with coronary artery disease, hypertension, diabetes mellitus, exposure to cardiotoxic drugs, alcohol abuse, or a family history of cardiomyopathy are at high risk for heart failure and may benefit from routine screening.

The treatment of adults with essential hypertension.

Hypertension is arbitrarily defined as diastolic blood pressure (DBP) of 90 mm Hg or higher, systolic blood pressure (SBP) of 140 mm Hg or higher, or both, on 3 separate occasions. Essential hypertension is hypertension without an identifiable cause. Essential hypertension, also known as primary or idiopathic hypertension, accounts for at least 95% of all cases of hypertension. According to the third National Health and Nutrition Examination Survey (NHANES III), approximately 60% of the 50 million Americans with hypertension are at increased risk for cardiovascular disease resulting from uncontrolled hypertension. This is because only 53% of hypertensive patients are being treated and only 24% have their hypertension under control. Physicians must play an active role in identifying and treating hypertension. In an earlier Applied Evidence article, an approach to the diagnosis of hypertension was presented. This article reviews the treatment of essential hypertension in adults and the prognosis of untreated hypertension. Risk stratification, alternative therapies, lifestyle modification, drug therapy, and prognosis will each be reviewed sequentially.
