Improving blood pressure control through provider education, provider alerts, and patient education: a cluster randomized trial.

BACKGROUND: Inadequate blood pressure control is a persistent gap in quality care. OBJECTIVE: To evaluate provider and patient interventions to improve blood pressure control. DESIGN: Cluster randomized, controlled trial. SETTING: 2 hospital-based and 8 community-based clinics in the Veterans Affairs Tennessee Valley Healthcare System. PATIENTS: 1341 veterans with essential hypertension cared for by 182 providers. Eligible patients had 2 or more blood pressure measurements greater than 140/90 mm Hg in a 6-month period and were taking a single antihypertensive agent. INTERVENTION: Providers who cared for eligible patients were randomly assigned to receive an e-mail with a Web-based link to the Seventh Report of the Joint National Committee on the Prevention, Detection, Evaluation and Treatment of High Blood Pressure (JNC 7) guidelines (provider education); provider education and a patient-specific hypertension computerized alert (provider education and alert); or provider education, hypertension alert, and patient education, in which patients were sent a letter advocating drug adherence, lifestyle modification, and conversations with providers (patient education). MEASUREMENTS: Proportion of patients with a systolic blood pressure less than 140 mm Hg at 6 months; intensification of antihypertensive medication. RESULTS: Mean baseline blood pressure was 157/83 mm Hg with no differences between groups (P = 0.105). Six-month follow-up data were available for 975 patients (73%). Patients of providers who were randomly assigned to the patient education group had better blood pressure control (138/75 mm Hg) than those in the provider education and alert or provider education alone groups (146/76 mm Hg and 145/78 mm Hg, respectively). More patients in the patient education group had a systolic blood pressure of 140 mm Hg or less compared with those in the provider education or provider education and alert groups (adjusted relative risk for the patient education group compared with the provider education alone group, 1.31 [95% CI, 1.06 to 1.62]; P = 0.012). LIMITATIONS: Follow-up blood pressure measurements were missing for 27% of study patients. The study could not detect a mechanism by which patient education improved blood pressure control. CONCLUSIONS: A multifactorial intervention including patient education improved blood pressure control compared with provider education alone.

Differences in antibiotic prescribing among physicians, residents, and nonphysician clinicians.

PURPOSE: State legislatures have increased the prescribing capabilities of nurse practitioners and physician assistants and broadened the scope of their practice roles. To determine the impact of these changes, we compared outpatient antibiotic prescribing by practicing physicians, nonphysician clinicians, and resident physicians. METHODS: Using the National Ambulatory Medical Care Survey (NAMCS) and the National Hospital Ambulatory Medical Care Survey (NHAMCS), we conducted a cross-sectional study of patients >/=18 years of age receiving care in 3 outpatient settings: office practices, hospital practices, and emergency departments, 1995-2000. We measured the proportion of all visits and visits for respiratory diagnoses where antibiotics are rarely indicated in which an antibiotic was prescribed by practitioner type. RESULTS: For all patient visits, nonphysician clinicians were more likely to prescribe antibiotics than practicing physicians for visits in office practices (26.3% vs 16.2%), emergency departments (23.8% vs 18.2%), and hospital clinics (25.2% vs 14.6%). Similarly, for the subset of visits for respiratory conditions where antibiotics are rarely indicated, nonphysician clinicians prescribed antibiotics more often than practicing physicians in office practices (odds ratio [OR] 1.86, 95% confidence intervals [CI]: 1.05 to 3.29), and in hospital practices (OR 1.55, 95% CI: 1.12 to 2.15). In hospital practices, resident physicians had lower prescribing rates than practicing physicians for all visits as well as visits for respiratory conditions where antibiotics are rarely indicated (OR 0.56, 95% CI: 0.36 to 0.86). CONCLUSION: Nonphysician clinicians were more likely to prescribe antibiotics than practicing physicians in outpatient settings, and resident physicians were less likely to prescribe antibiotics. These differences suggest that general educational campaigns to reduce antibiotic prescribing have not reached all providers.

Trends in antibiotic prescribing for adults in the United States--1995 to 2002.

CONTEXT: The impact of national efforts to limit antibiotic prescribing has not been fully evaluated. OBJECTIVES: To analyze trends in outpatient visits associated with antibiotic prescription for U.S. adults. DESIGN: Cross-sectional study of data (1995 to 2002) from the National Ambulatory Medical Care Survey and the National Hospital Ambulatory Medical Care Survey. PARTICIPANTS: Adults > or =18 years with an outpatient visit to an office- or hospital-based medical practice or to an emergency department. All visits were classified into 1 of 4 diagnostic categories: (1) acute respiratory infection (ARI)-antibiotics rarely indicated, (2) ARI-antibiotics often indicated, (3) nonrespiratory infection-antibiotics often indicated, and (4) all others. MEASUREMENTS: Trends in: (1) Proportion of outpatient visits associated with an antibiotic prescription; (2) proportion of antibiotic prescriptions that were broad spectrum; and (3) number of visits and antibiotic prescriptions per 1,000 U.S. adults > or =18 years of age. RESULTS: From 1995-1996 to 2001-2002, the proportion of all outpatient visits that generated an antibiotic prescription decreased from 17.9% to 15.3% (adjusted odds ratio [OR] 0.84, 95 % confidence interval [CI] 0.76 to 0.92). The entire reduction was because of a decrease in antibiotic prescriptions associated with visits for ARIs where antibiotics are rarely indicated from 59.9% to 49.1% (adjusted OR 0.64 95% CI 0.51 to 0.80). However, the proportion of prescribed antibiotics for these visits that were classified as broad-spectrum antibiotic prescription increased from 41.0% to 76.8%. Overall outpatient visits increased from 1693 to 1986 per 1,000 adults over the 8 years studied, but associated antibiotic prescriptions changed little, from 302 to 304 per 1,000 adults. CONCLUSION: During the study period, outpatient antibiotic prescribing for respiratory infections where antibiotics are rarely indicated has declined, while the proportion of broad-spectrum antibiotics prescribed for these diagnoses has increased significantly. This trend resulted in a 15% decline in the total proportion of outpatient visits in which antibiotics were prescribed. However, because outpatient visits increased 17% over this time period, the population burden of outpatient antibiotic prescriptions changed little.

Prescriptions for chronic high-dose cyclooxygenase-2 inhibitors are often inappropriate and potentially dangerous.

OBJECTIVE: To describe the use of coxibs outside of licensed indications and recommended dosing ranges including rofecoxib 50 mg, valdecoxib 20 to 40 mg, and celecoxib 400 mg. DESIGN: Cross-sectional study of coxib utilization in 2002 and 2003 and retrospective cohort analysis of new users. PARTICIPANTS: Patients with known age and sex enrolled in Tennessee's Medicaid program. MEASUREMENTS: The prevalence of coxib use by dose and duration, and the proportion of persons initially prescribed a high-dose coxib and indications for such use. RESULTS: The estimated daily prevalence of nonaspirin prescription nonsteroidal anti-inflammatory drugs (NSAIDs) was 8.7% in 2002 to 2003 (45.7% coxibs). NSAID use peaked at age 65 to 74 with a prevalence of 19.8% (56.3% coxibs). Doses above the recommended daily dose for osteoarthritis accounted for 33.2% (95% confidence intervals [CIs] 32.4%, 33.9%) of celecoxib use, 14.9% (95% CI 14.4%, 15.5%) of rofecoxib use, and 52.2% (95% CI 50.6%, 53.8%) of valdecoxib use. Most of these prescriptions were for a month's supply. For new coxib users, 13.5% were given a month's supply for the highest dose category, and 28% refilled their prescriptions within 7 days of the end of the original prescription. Of these new chronic high-dose users, 17.2% had ischemic heart disease and 7.1% had heart failure. CONCLUSIONS: A substantial portion of coxib prescriptions were for a month's supply at doses above those recommended for most chronic indications. New users were also prescribed high doses despite evidence for cardiovascular comorbidity. These prescribing patterns at doses outside licensed indications are both inappropriate and potentially dangerous.

A three-part intervention to change the use of hormone replacement therapy in response to new evidence.

BACKGROUND: Slow adaptation of new information by providers may result in suboptimal care. OBJECTIVE: To evaluate changes in prescriptions for combination hormone replacement therapy (HRT) after a multicomponent intervention to deliver new information to patients and providers. DESIGN: Quasi-experimental study with multiple baselines. SETTING: Veterans Affairs Tennessee Valley Healthcare System (VA-TVHS). PATIENTS: Female veterans age 50 to 79 years who had a prescription filled at the VA-TVHS for combination HRT between 1 January 2002 and 1 July 2002. MEASUREMENTS: Discontinuation of HRT. INTERVENTION: A 3-part intervention consisted of 1) notifying patients who were using combination HRT of the results of the Women's Health Initiative study (patient education component), 2) sending all providers an e-mail with the Women's Health Initiative study results (provider education component), and 3) placing an electronic alert in each eligible patient's chart (provider care component). The alert asked providers to reevaluate the need for combination HRT. The intervention was implemented at different VA-TVHS sites in a stepwise fashion to differentiate intervention effect from media effect. Study follow-up continued through 31 December 2002. RESULTS: The total rate of discontinuation of combination HRT was 70.3% in 2002. The proportion of discontinuation from time of media release until intervention was 23.3%. After initiation of the intervention, an additional 43% of the original cohort discontinued use of HRT; this percentage represents a 59% relative decrease in HRT use among patients. After adjustment for time, the discontinuation rate per day was 4.9 times higher after the multifacted intervention than after the media release (95% CI, 1.8 to 13.1). LIMITATIONS: A true control group is lacking. CONCLUSION: A multifaceted approach in an integrated health care system with standardized methods of communication is an effective way to implement patient-centered, effective, and timely care with changing medical knowledge.

Improving documentation of patient acuity level using a progress note template.

BACKGROUND: Accurately documenting patient comorbidities and complications improves case-mix representation, coding accuracy, and risk-adjusted mortality estimates for benchmarking. We hypothesized that a progress note template containing comorbidities and complications would improve documentation and teach residents to correctly document comorbidities and complications. STUDY DESIGN: Surgical residents and patients on three inpatient services were followed for a 1-year prospective cohort study. After a 6-month baseline period, a progress note template was developed and implemented for 6 months, and administrative data were retrieved. Residents were given three case examinations assessing documentation knowledge pre- and postintervention, and a satisfaction survey. Demographics, Charlson comorbidity score, ICD-9 codes, template-specific ICD-9 codes, All Patient Refined (APR)-DRG patient severity, DRG relative weight, predicted mortality (University Healthcare Consortium), pre- and postexam scores, and resident satisfaction were collected. RESULTS: No difference in age, gender, race, or Charlson comorbidity score existed between pre- and postintervention patient groups. The length of stay decreased from 5.5 days to 4.8 days (p = 0.013). In the intervention group, total ICD-9 codes, template-specific ICD-9 codes, APR-DRG, DRG weight, and UHC predicted mortality had significant increases. Residents exposed to the progress note template improved their knowledge scores from 52% to 63% (p < 0.001), and 73% agreed that the progress note template was an improvement over handwritten notes. Residents not exposed to the progress note template did not improve their scores. CONCLUSIONS: A progress note template improves documentation of comorbidities and complications, APR-DRG patient severity for benchmarking, and case-mix index, and increases patient-specific predicted mortality. The progress note template also improves surgical residents' documentation knowledge and satisfaction.

Over-the-counter analgesics in older adults: a call for improved labelling and consumer education.

The use of analgesics increases with age and on any given day 20-30% of older adults take an analgesic medication. Over-the-counter (OTC) analgesics are generally well tolerated and effective when taken for brief periods of time and at recommended dosages. However, their long-term use, use at inappropriately high doses, or use by persons with contraindications may result in adverse effects, including gastrointestinal haemorrhage, cardiovascular toxicity, renal toxicity and hepatotoxicity. Many OTC drugs are also available through a prescription, for a broader range of indications and for longer durations of use and wider dose ranges, under the assumption that healthcare providers will help patients make safe choices about analgesics. Safe and effective use of medications is one of the greatest challenges faced by healthcare providers in medicine. More than 60% of people cannot identify the active ingredient in their brand of pain reliever. Additionally, about 40% of Americans believe that OTC drugs are too weak to cause any real harm. As a result of a recent US FDA policy, the conversion of prescription to OTC medications will result in a 50% increase of OTC medications. To reduce the risks of potential adverse effects from OTC drug therapy in older adults, we propose that the use of analgesics will be enhanced through the use of patient and healthcare provider education, as well as improved labelling of OTC analgesics. Improved labelling of OTC analgesics may help consumers distinguish common analgesic ingredients in a wide variety of preparations and facilitate informed decisions concerning the use of OTC drugs.
