Examining the sustainability potential of a multisite pilot to integrate alcohol screening and brief intervention within three primary care systems.

The U.S. Preventive Services Task Force recommends that clinicians adopt universal alcohol screening and brief intervention as a routine preventive service for adults, and efforts are underway to support its widespread dissemination. The likelihood that healthcare systems will sustain this change, once implemented, is under-reported in the literature. This article identifies factors that were important to postimplementation sustainability of an evidence-based practice change to address alcohol misuse that was piloted within three diverse primary care organizations. The Centers for Disease Control and Prevention funded three academic teams to pilot and evaluate implementation of alcohol screening and brief intervention within multiclinic healthcare systems in their respective regions. Following the completion of the pilots, teams used the Program Sustainability Assessment Tool to retrospectively describe and compare differences across eight sustainability domains, identify strengths and potential threats to sustainability, and make recommendations for improvement. Health systems varied across all domains, with greatest differences noted for Program Evaluation, Strategic Planning, and Funding Stability. Lack of funding to sustain practice change, or data monitoring to promote fit and fidelity, was an indication of diminished Organizational Capacity in systems that discontinued the service after the pilot. Early assessment of sustainability factors may identify potential threats that could be addressed prior to, or during implementation to enhance Organizational Capacity. Although this study provides a retrospective assessment conducted by external academic teams, it identifies factors that may be relevant for translating evidence-based behavioral interventions in a way that assures that they are sustained within healthcare systems.

Use and perceptions of antibiotics for upper respiratory infections among college students.

BACKGROUND: Upper respiratory infections (URIs) are mainly viral in nature, rendering antibiotics ineffective. Little is known about what college students believe concerning the effectiveness of antibiotics as a treatment for URIs. METHODS: Students (n=425) on 3 college campuses were surveyed using a survey describing 3 variations in presentation of an uncomplicated URI. Participants were questioned about their likelihood of using a variety of treatments for the URI and about their likelihood of seeking a physician's care. RESULTS: The percentage of students endorsing antibiotic use differed significantly by symptom complex. Likelihood of seeking medical care also differed significantly across symptom groups, with greater endorsement in the discolored nasal discharge and low-grade fever scenarios. Stepwise multiple regression analysis revealed that belief in antibiotic effectiveness for cold symptoms decreased with tic and Therapeutic increasing years of higher education. Likelihood of antibiotic use across different scenarios increased with age. Likelihood of seeking care across different scenarios was related to type of health insurance and belief in antibiotic effectiveness. CONCLUSIONS: Undergraduate college students show poor recognition of typical presentations of the common cold and have misconceptions about effective treatment. Although increasing years of college correlated with decreasing belief in antibiotics' effectiveness for a cold, more health education at the college level is recommended.

Alternative therapies: Part II. Congestive heart failure and hypercholesterolemia.

Natural supplements are widely used by the American public but, while claims of their therapeutic effects abound, medical research does not always support their effectiveness. Clinical trials using Q10 for the management of congestive heart failure have had conflicting results; hawthorn is prescribed in Germany for the treatment of this condition, but no trials have been conducted in the United States. Although initial research about the use of garlic in the management of hypercholesterolemia was encouraging, follow-up studies have failed to verify these results. Substituting soy protein for high-fat animal protein diets, however, does have a beneficial effect on serum lipid levels. So far, cholestin (a natural product containing several statins) has proved to be a cost-saving lipid-lowering medication, and fenugreek may offer modest improvement as well. Gugulipid is also promising but requires further research.

Alternative therapies: Part I. Depression, diabetes, obesity.

Natural supplements are widely used in the United States and, while claims of their therapeutic effects abound, medical research does not always support their effectiveness. St. John's wort acts as a weak selective serotonin reuptake inhibitor with fewer side effects. S-Adenosylmethionine (SAMe) has enough of an antidepressant effect to warrant further research. More human studies are needed before garlic, bitter melon, soy and fenugreek supplements can be recommended for the management of diabetes, although chromium may be a promising treatment in some cases. Alpha lipoic acid is used in the treatment of diabetic neuropathy. The effects of ma huang/guarana combinations in obesity have not been well studied. These combinations may have potentially serious side effects but may also offer some benefit. The combination of hydroxycitric acid and garcinia has proved no more effective than placebo.

Hypertension.

The current JNC-VI criteria for diagnosis and classification of hypertension are discussed. The laboratory evaluation of both essential and secondary hypertension is examined, and recommendations are made in this regard. Finally, the complications and treatment of essential hypertension and the causes and management of resistant hypertension are discussed.

A managed care curriculum: developing a managed care curriculum for primary care residents.

INTRODUCTION: Managed care in its numerous forms is continuing to change the face of the healthcare system in the United States. IMPACT OF MANAGED CARE ON MEDICAL EDUCATION: As managed care continues to invade the market, it has a substantial influence in shaping the parameters of graduate medical education. Various surveys have shown that residents are under-trained in managed care principles and practice. There is a clear need for a residency curriculum that fully prepares students to keep pace with modern markets. EDUCATIONAL METHODOLOGY: This manuscript describes a curriculum which emphasizes the role of the primary care physician, cost-effective practice, multidisciplinary practice and evidenced-based strategies. Educational methods and concepts presented here are based on the recommendations of healthcare educators, extensive literature searches and United States advisory panels. After the curriculum is completed, the resident will: 1. Practice cost-effectively under 100% capitation and learn proper risk management. 2. Utilize epidemiological thinking and community-oriented primary care. 3. Function as a part of healthcare team and understand how to achieve cost-effective care for patients. 4. Practice the principles of continuous quality improvement and assess patient satisfaction. 5. Practice and adopt evidence-based medicine and guidelines. 6. Become skilled with computers including facility with literature searches, databases and the internet. 7. Practice a full spectrum of primary care emphasizing patient education and psychosocial health. 8. Understand the ethical issues pertinent to managed care practices. EVALUATION: The residency curriculum committee will evaluate the managed care curricular elements on an on-going basis. CONCLUSION: This comprehensive curriculum for primary care residents can help ensure success in the new healthcare marketplace.

Practice patterns for peptic ulcer disease: are family physicians testing for H. pylori?

BACKGROUND: Peptic ulcer disease (PUD) is a problem common in family medicine. Recent evidence of Helicobacter pylori as an etiological agent of PUD has led to National Institutes of Health recommendations for treatment to eradicate H. pylori through antibiotic therapy. The purpose of this study is to examine practice patterns of family physicians in treating PUD, their use of H. pylori testing, and knowledge of current recommendations for PUD. MATERIALS AND METHODS: A mail survey was sent to a random sample of 1,500 members of the American Academy of Family Physicians. Six hundred thirty useable surveys (49.1%) were available for analysis. Descriptive statistics were obtained, as were inferential statistics focusing on the relationship of physician background characteristics to practices. RESULTS: Thirty-eight percent of the respondents order diagnostic procedures for the majority (50% or more) of their suspected PUD cases. Of the physicians who reported ordering any diagnostic tests, 52% ordered the combination of upper gastrointestinal series and endoscopic gastroduodenoscopy. For patients with clinical diagnoses of PUD, 77% of doctors reported ordering a diagnostic test for H. pylori. Approximately 68% were aware that some kind of guidelines existed; only 11% reported that they were familiar with the National Institutes of Health recommendations for PUD. CONCLUSIONS: Although some of the practices of family physicians for treatment of PUD deviate from current recommendations, the majority of practices are consistent with current evidence.

Screening and referral patterns for glaucoma in family practice.

The purpose of this study was to determine whether family physicians in Louisiana were (1) aware of risk factors for glaucoma; and (2) complying with USPSTF recommendations. A brief, confidential survey was mailed to family physicians. Knowledge of glaucoma and its risk factors was assessed, as were physicians' decisions to refer high-risk patients for ophthalmologic evaluation. Questions addressed awareness of treatment guidelines and screening of glaucoma, as well as select demographic data. A total of 533 surveys were distributed. Sixty-three surveys were returned by the post office, which left a usable sample size of 470. The overall response rate was 40.22% (N = 189). Seventy percent of respondents considered diabetes and hypertension risk factors. Roughly 25% routinely screened high-risk patients for glaucoma; 75% did not. Sixty percent showed correct clinical judgment in referring patients to ophthalmologists based on history and physical examination. Sixty-five percent of respondents were unaware of any guidelines or consensus statements for the treatment of glaucoma. While most family physicians can identify risk factors for glaucoma, they do not routinely screen for patients with high-risk factors.

A different look at corticosteroids.

Systemic corticosteroids have been used in the treatment of numerous medical conditions for approximately 50 years. Short-acting products such as hydrocortisone are the least potent. Prednisone and methylprednisolone, which are intermediate-acting products, are four to five times more potent than hydrocortisone. Dexamethasone is a long-acting, systemic corticosteroid; its potency is about 25 times greater than the short-acting products. Corticosteroids reduce the need for hospitalization in patients with croup and decrease morbidity and the incidence of respiratory failure in the treatment of patients with AIDS who have Pneumocystis carinii pneumonia. Other often overlooked indications for corticosteroids are the treatment of hyperthyroid states, including thyroid storm, subacute thyroiditis and ophthalmopathy of Graves' disease. Systemic steroids can be used as adjuvant analgesics in the treatment of neuropathic and cancer-related pain. They may also decrease mortality in patients with severe alcoholic hepatitis and concomitant encephalopathy. Corticosteroids can reduce complications in patients with meningitis caused by Haemophilus influenzae or Mycobacterium tuberculosis.

Guidelines on the care of diabetic nephropathy, retinopathy and foot disease.

Diabetes mellitus is a common disease frequently managed by family physicians. Because of its high prevalence and associated comorbidity, diabetes mellitus has received a great deal of attention from several specialty organizations. The American Diabetes Association, the American Board of Family Practice and the Centers for Disease Control and Prevention have published specific practice guidelines and recommendations for the care of diabetic patients. These recommendations include annual comprehensive foot examinations, yearly ophthalmologic screening for retinopathy, and urinalysis for microalbuminuria. The use of angiotensin converting enzyme inhibitors is advocated for the majority of diabetic patients with proteinuria or hypertension. Based on recent evidence, improved glycemic control is also increasingly advocated. Compliance with practice guidelines by primary care physicians has historically been poor. Mechanisms such as the use of patient problem lists and diabetic flow sheets can serve as reminders to physicians and can facilitate closer adherence to practice guidelines.

Patient knowledge of upper respiratory infections: implications for antibiotic expectations and unnecessary utilization.

BACKGROUND: Upper respiratory infections (URIs) account for many of the visits in primary care and are commonly treated with ineffective antibiotic therapy. The purpose of this study was to examine patient beliefs in the effectiveness of antibiotics and the likelihood of seeking care for normal presentations of URIs. METHODS: We conducted a survey of 961 adults (> or = 18 years of age) from an undifferentiated patient population in a university-based family practice residency clinic in metropolitan Kentucky, a private internal medicine practice in nonmetropolitan Kentucky, and, in metropolitan Louisiana, an emergency department and a convenience sample from the community. RESULTS: Seventy-two percent of the sample reported that they would seek care with a condition of 5 days' duration with cough, sore throat, and discolored nasal discharge. Sixty-one percent of the sample expressed their belief that antibiotics are effective for a condition of 5 days' duration with cough, sore throat, and clear nasal discharge; 79% said that they believed antibiotics are effective when there is discolored discharge (P = .0001). Medicaid recipients were most likely to seek care across the symptom complexes. Higher education was related to a decreased belief in the effectiveness of antibiotics for the scenario with clear discharge (P .001), but to an increased belief in the effectiveness of antibiotics in the scenario with discolored discharge (P = .003). The strongest predictor of both likelihood of utilization and belief in effectiveness of antibiotics was usual use of antibiotics for the URI symptom complexes. CONCLUSIONS: Patients lack understanding of the normal presentation of a URI and the effectiveness of antibiotics as a treatment. A confusion about the meaning of discolored nasal discharge is particularly evident, and past antibiotic use may contribute to inappropriate utilization and expectations for antibiotics.

Streptococcal diagnostic testing and antibiotics prescribed for pediatric tonsillopharyngitis.

BACKGROUND: This study examined a 1-year cross-sectional sample of Kentucky Medicaid claims for the use of streptococcal diagnostic tests for pediatric tonsillopharyngitis and the empiric use of antibiotics. METHODS: Subjects were individuals older than 3 and younger than 18 years old seen in an ambulatory setting for tonsillopharyngitis; 3478 individuals accounted for the 5067 separate outpatient and emergency room encounters for pediatric tonsillopharyngitis; 849 encounters coded as streptococcal sore throat were also examined. RESULTS: Diagnostic tests for group A streptococcal tonsillopharyngitis were performed in only 22% (n = 1130) of the tonsillopharyngitis encounters and 36% (n = 306) of the streptococcal sore throat encounters. Urban physicians were more likely than rural physicians to use a diagnostic test (P = 0.0001). Emergency room encounters and outpatient encounters were not significantly different in the likelihood of having a diagnostic test (P = 0.16). In encounters for tonsillopharyngitis antibiotics were prescribed in 72% of the total encounters and in 73% of the encounters without a diagnostic streptococcal test. In encounters for streptococcal sore throat, antibiotics were prescribed for 68% of the total encounters and 69% of the encounters without a diagnostic streptococcal test. CONCLUSIONS: Current practices in the Kentucky Medicaid program do not follow the American Academy of Pediatrics guidelines for streptococcal tonsillopharyngitis.

Practice patterns of rural family physicians based on the American Diabetes Association standards of care.

The purpose of this study was to examine practice patterns of rural family physicians in the care of non-insulin-dependent diabetes mellitus based on the standards of care of the American Diabetes Association (ADA). One hundred patient charts were randomly chosen, twenty for each physician, from the practices of five family physicians in rural Ohio. A standardized collection protocol was used, based upon the ADA recommendations. The charts were reviewed for compliance with the ADA parameters. The patients' records demonstrated 66% compliance with dietary counseling and 33% with counseling about exercise. Moreover, there was low compliance with physical examination guidelines. Specifically, 66% of the patients had fundoscopic examination and 64% had a complete foot examination done. With respect to the laboratory guidelines, 70% of the charts reviewed had a urinalysis ordered and 45% annual lipids measured. However, glycosylated hemoglobin was performed in only 15% of the patients. The results suggest that rural family physicians do not consistently follow the ADA standards of care.

Current management of acute bronchitis in ambulatory care: The use of antibiotics and bronchodilators.

OBJECTIVE: To examine the treatment regimens for acute bronchitis in adults in a Medicaid population seen in ambulatory care settings. DESIGN: Cross-sectional sample of Kentucky Medicaid claims (July 1, 1993, through June 30, 1994). PARTICIPANTS: Individuals 18 years old or older seen in an ambulatory setting for acute bronchitis. Anyone with a primary diagnosis of asthma or chronic obstructive pulmonary disease within the time frame was excluded. Twelve hundred ninety-four individuals accounted for 1635 separate outpatient and emergency department encounters for acute bronchitis. Outpatient visits accounted for 89% (n=1448) of the encounters. RESULTS: In 22% (n=358) of the encounters, no medication was prescribed; in 61% (n=997), antibiotics alone were prescribed, in 3% (n=43), bronchodilators alone were prescribed; and in 14% (n=237), both antibiotics and bronchodilators were prescribed. Some type of medication was more likely to be prescribed in emergency departments than in outpatient settings (P=.04), and antibiotic/bronchodilator combination therapy was more likely to be prescribed in rural practices than in urban practices (P<.001). Broad-spectrum were more likely than narrow-spectrum antibiotics to be used in combination with a bronchodilator (P=.001). Penicillins were the most widely used antibiotics (37%), but broad-spectrum agents, such as second- and third-generation cephalosporins (10%) and fluoroquinolones (5%), were also prescribed. CONCLUSIONS: Although evidence suggests that antibiotic treatment is not usually indicated for treatment of acute bronchitis, these results indicate that antibiotics are still the predominant treatment regimen in ambulatory care. Furthermore, the evidence suggesting that bronchodilators are effective symptomatic treatments has not been widely adopted. These results have significant implications for the production of antibiotic-resistant bacteria and suggest investigation into why physicians have not used this information in their treatment of acute bronchitis.
