A randomized trial at a family medicine center compared three ways of improving the rates of recording patients' smoking behavior: letter, telephone, and reminding physicians to inquire at visits. Telephone produced the highest rate of recordings, while physician reminder was most cost-effective. We recommend physician reminder with telephone calls from the practice nurse for patients who do attend.

OBJECTIVE: To assess the impact of an automated intraoperative alert to redose prophylactic antibiotics in prolonged cardiac operations. DESIGN: Randomized, controlled, evaluator-blinded trial. SETTING: University-affiliated hospital. PATIENTS: Patients undergoing cardiac surgery that lasted more than 4 hours after the preoperative administration of cefazolin, unless they were receiving therapeutic antibiotics at the time of surgery. INTERVENTION: Randomization to an audible and visual reminder on the operating room computer console at 225 minutes after the administration of preoperative antibiotics (reminder group, n = 137) or control (n = 136). After another 30 minutes, the circulating nurse was required to indicate whether a follow-up dose of antibiotics had been administered. RESULTS: Intraoperative redosing was significantly more frequent in the reminder group (93 of 137; 68%) than in the control group (55 of 136; 40%) (adjusted odds ratio, 3.31; 95% confidence interval, 1.97 to 5.56; P < .0001). The impact of the reminder was even greater when compared with the 6 months preceding the study period (129 of 480; 27%; P < .001), suggesting some spillover effect on the control group. Redosing was formally declined for 19 of the 44 patients in the reminder group without redosing. The rate of surgical-site infection in the reminder group (5 of 137; 4%) was similar to that in the control group (8 of 136; 6%; P = .42), but significantly lower than that in the pre-study period (48 of 480; 10%; P = .02). CONCLUSION: The use of an automatic reminder system in the operating room improved compliance with guidelines on perioperative antibiotic prophylaxis.

BACKGROUND: Deciding which patients should receive thrombolytic therapy or percutaneous transluminal coronary angioplasty (PTCA) for acute myocardial infarction (AMI) can be difficult, especially for less-obvious candidates and when consulting physicians are off site. OBJECTIVE: To test whether the electrocardiograph-based Thrombolytic Predictive Instrument (TPI) improves use of thrombolytic and overall reperfusion therapy. DESIGN: 22-month randomized, controlled, clinical effectiveness trial. SETTING: Emergency departments at 28 urban, suburban, and rural hospitals in the United States. PATIENTS: Persons presenting to the emergency department with AMI and ST-segment elevation on an electrocardiogram (ECG). INTERVENTION: TPI predictions automatically printed on ECG text headers. MEASUREMENTS: Percentages of patients receiving thrombolytic therapy, thrombolytic therapy within 1 hour of initial ECG, and overall reperfusion (thrombolytic therapy or PTCA). RESULTS: Of 2875 patients with AMI, 1243 (43.2%) had ST-segment elevation. Of these, 1197 were randomly assigned to study groups; 732 (61.2%) had inferior AMI, and 465 (38.8%) had anterior AMI. A total of 60.5% of controls and 62.1% of TPI patients (P = 0.2) received thrombolytic therapy, 52.5% of controls and 53.3% of TPI patients received thrombolytic therapy within 1 hour (P > 0.2), and 67.6% of controls and 70.3% of TPI patients received overall reperfusion (P = 0.2). Of patients with inferior AMI in the control group versus the TPI group, 61.1% versus 67.6% (P = 0.03) received thrombolytic therapy, 53.2% versus 58.6% (P = 0.08) received thrombolytic therapy within 1 hour, and 67.7% versus 74.7% (P = 0.03) received overall reperfusion. Of patients with anterior AMI in the control group versus the TPI group, 59.5% versus 53.9% (P > 0.2) received thrombolytic therapy, 51.4% versus 45.3% (P > 0.2) received thrombolytic therapy within 1 hour, and 67.6% versus 63.8% (P > 0.2) received overall reperfusion. Among women (n = 398) in the control group versus the TPI group, 48.1% versus 58.2% (P = 0.03) received thrombolytic therapy, 40.5% versus 48.4% (P = 0.10) received thrombolytic therapy within 1 hour, and 55.7% versus 65.7% (P = 0.04) received overall reperfusion. Of patients who required physician consultation by telephone (n = 271) in the control group versus the TPI group, 47.3% versus 63.2% (P = 0.01) received thrombolytic therapy, 41.1% versus 53.6% (P = 0.04) received thrombolytic therapy within 1 hour, and 50.7% versus 66.4% (P = 0.01) received overall reperfusion. CONCLUSIONS: The TPI increased use of thrombolytic therapy, use of thrombolytic therapy within 1 hour, and use of overall coronary reperfusion by 11% to 12% for patients with inferior AMI, 18% to 22% for women, and 30% to 34% for patients with an off-site physician. Although its effect was minimal on patients with high baseline reperfusion rates, the TPI increased use and timeliness of reperfusion in often-missed groups and when involved physicians were off site.

OBJECTIVE: To develop a longitudinal model to characterize the delivery of mammography services using repeated observations of mammography referral rates during a randomized controlled trial (RCT) of physician mammography reminders. DATA SOURCES/STUDY SETTING: Administrative records of a health department and observational data on mammography appointment scheduling. STUDY DESIGN: The design was a longitudinal study of month-specific referral rates during a 1-year RCT. A retrospective case-control study was used to investigate differences between women with timely and delayed (or absent) mammography referral assessed at the end of the intervention year. DATA COLLECTION/EXTRACTION METHODS: Month-specific indicators for referrals and missed clinical opportunities, that is, months when clinic visitors were due for a mammogram and not referred, were constructed using administrative and observational data. FINDINGS: In the unadjusted analysis, the effectiveness of the reminder declined over time. However, in a multivariate analysis that controlled for the number of missed opportunities, the effectiveness was constant over time. On a monthly basis, physician reminders were significantly associated with higher referral rates among clinic visitors newly due for mammography (adjusted OR = 2.8, 95 percent CI = 1.3, 5.8) or who had one previously missed clinical opportunity (adjusted OR = 3.0, 95 percent CI = 1.6, 5.3) but were not for those with two or more missed clinical opportunities (adjusted OR = 1.2, 95 percent CI = 0.7, 2.3). Factors independently associated with delayed referral were age over 65, presence of more than one chronic illness, and the absence of a physician mammography reminder. CONCLUSIONS: Longitudinal models that examine rates of referral over time and include information about outcomes on previous visits can enhance our understanding of how intervention strategies work in practice.

OBJECTIVE: To evaluate the use of a computerised support system for decision making for implementing evidence based clinical guidelines for the management of asthma and angina in adults in primary care. DESIGN: A before and after pragmatic cluster randomised controlled trial utilising a two by two incomplete block design. Setting: 60 general practices in north east England. PARTICIPANTS: General practitioners and practice nurses in the study practices and their patients aged 18 or over with angina or asthma. MAIN OUTCOME MEASURES: Adherence to the guidelines, based on review of case notes and patient reported generic and condition specific outcome measures. RESULTS: The computerised decision support system had no significant effect on consultation rates, process of care measures (including prescribing), or any patient reported outcomes for either condition. Levels of use of the software were low. CONCLUSIONS: No effect was found of computerised evidence based guidelines on the management of asthma or angina in adults in primary care. This was probably due to low levels of use of the software, despite the system being optimised as far as was technically possible. Even if the technical problems of producing a system that fully supports the management of chronic disease were solved, there remains the challenge of integrating the systems into clinical encounters where busy practitioners manage patients with complex, multiple conditions.

CONTEXT: Prescribing practices for otitis media are not consistent with current evidence-based recommendations. OBJECTIVE: To determine whether point-of-care evidence delivery regarding the use and duration of antibiotics for otitis media decreases the duration of therapy from 10 days and decreases the frequency of prescriptions written. DESIGN: Randomized, controlled trial. SETTING: Primary care pediatric clinic affiliated with university training program. Intervention. A point-of-care evidence-based message system presenting real time evidence to providers based on their prescribing practice for otitis media. MAIN OUTCOME MEASURES: Proportion of prescriptions for otitis media that were for <10 days and frequency with which antibiotics were prescribed. RESULTS: Intervention providers had a 34% greater reduction in the proportion of time they prescribed antibiotics for <10 days. Intervention providers were less likely to prescribe antibiotics than were control providers. CONCLUSIONS: A point-of-care information system integrated into outpatient pediatric care can significantly influence provider behavior for a common condition.

OBJECTIVES: To examine the effectiveness and cost-effectiveness of two primary care based interventions aimed at increasing breast screening uptake for women who had recently failed to attend. SETTING: 13 General practices with low uptake in the second round of breast screening (below 60%) in north west London and the West Midlands, United Kingdom. Participants were women in these practices who were recent non-attenders for breast screening in the third round. METHODS: Pragmatic factorial randomised controlled trial, with people randomised to a systematic intervention (general practitioner letter), an opportunistic intervention (flag in women's notes prompting discussion by health professionals), neither intervention, or both. Outcome measures were attendance for screening 6 months after randomisation and cost-effectiveness of the interventions. RESULTS: 1,158 Women were individually randomised as follows: 289 control; 291 letter; 290 flag; 288 both interventions. Attendance was ascertained for 1,148 (99%) of the 1,158 women. Logistic regression adjusting for the other intervention and practice produced an odds ratio (OR) for attendance of 1.51 (95% confidence interval (95% CI 1.02 to 2.26; p=0.04) for the letter, and 1.39 (95% CI 0.93 to 2.07; p=0.10) for the flag. Health service costs/ additional attendance were 35 pounds (letter) and 65 pounds (flag). CONCLUSIONS: Among recent non-attenders, the letter was effective in increasing breast screening attendance. The flag was of equivocal effectiveness and was considerably less cost-effective than the letter.

BACKGROUND: Different methods for changing blood test-ordering behavior in primary care have been proven effective. However, randomized trials comparing these methods are lacking. OBJECTIVE: To compare the effect of two versions of BloodLink, a computer-based clinical decision support system, on blood test ordering among general practitioners. DESIGN: Randomized trial. SETTING: 44 practices of general practitioners in the region of Delft, the Netherlands. PARTICIPANTS: 60 general practitioners in 44 practices who used computer-based patient records in their practices. INTERVENTION: After stratification by solo practices and group practices, practices were randomly assigned to use BloodLink-Restricted, which initially displays a reduced list of tests, or BloodLink-Guideline, which is based on the guidelines of the Dutch College of General Practitioners. MEASUREMENTS: Average number of blood tests ordered per order form per practice. RESULTS: General practitioners who used BloodLink-Guideline requested 20% fewer tests on average than did practitioners who used BloodLink-Restricted (mean [+/-SD], 5.5 +/- 0.9 tests vs. 6.9 +/- 1.6 tests, respectively; P = 0.003, Mann-Whitney test). CONCLUSIONS: Decision support based on guidelines is more effective in changing blood test-ordering behavior than is decision support based on initially displaying a limited number of tests. Guideline-driven decision support systems can be effective in reducing the number of laboratory tests ordered by primary care practitioners.

CONTEXT: Nonsteroidal anti-inflammatory drugs (NSAIDs) are among the most frequently prescribed drugs for patients 65 years of age or older, primarily for musculoskeletal symptoms of osteoarthritis. Because NSAIDs frequently cause serious gastrointestinal (GI) and other complications among elderly patients, expert guidelines for osteoarthritis recommend acetaminophen-based regimens, which are safer and often as effective as NSAIDs. OBJECTIVE: Evaluate a physician education program that communicated guidelines for management of osteoarthritis in elderly patients that emphasized avoidance of NSAIDs when possible. The program reviewed NSAID risks and benefits and recommended: re-evaluating continuous NSAID users, considering substitution of up to 4 g/d of acetaminophen for the NSAID, and trying topical agents and nonpharmacologic measures. DESIGN AND SETTING: Randomized controlled trial among community-dwelling Tennessee Medicaid enrollees. SUBJECTS: Study physicians had 5 or more patients who: were community-dwelling Medicaid enrollees 65 years of age or older; had used NSAIDs regularly for at least 180 days; had had no medical care encounters during this period suggesting an indication other than osteoarthritis; and had 1 year of baseline and follow-up data. The study thus included 209 physicians (103 intervention/106 control) with 1,566 qualifying regular NSAID users (768/798). INTERVENTIONS: Face-to-face visit to study physicians by another physician, and reminder placements in the charts of patients eligible to have NSAID use reevaluated. OUTCOMES: Change between baseline and follow-up years in: days of prescribed NSAIDs, acetaminophen, other drugs for musculoskeletal disorders, and GI drugs; outpatient visits and inpatient days of stay; SF36 measures of general health, physical function, and bodily pain (from 40% random patient sample); and over-the-counter NSAIDs (from the sample). RESULTS: Intervention-attributable reduction of 7% (95% CI, 3% to 11%) in days of prescribed NSAIDs use with concomitant increase in acetaminophen use. No significant changes in other study endpoints. The intervention effect was greater among 75 physicians with a completed study visit, whose 564 patients had a 10% (95% CI, 6% to 14%) attributable reduction in NSAID use. CONCLUSIONS: The educational program modestly reduced NSAID exposure in community-dwelling elderly patients without undesirable substitution of other medications or detectable worsening of musculoskeletal symptoms.
