Self-reported familiarity with acute respiratory infection guidelines and antibiotic prescribing in primary care

Impact evaluation of a brief online training module on physician use of the Maryland, USA, Prescription Drug Monitoring Program

Background

Prescription Drug Monitoring Programs (PDMPs) are electronic databases that track controlled substance prescriptions in a state. They are underused tools in preventing opioid abuse. Most PDMP education research measures changes in knowledge or confidence rather than behavior.

Objective

To evaluate the impact of online case-based training on healthcare provider use of the Maryland (USA) PDMP.

Methods

We used e-mail distribution lists to recruit providers to complete a brief educational module. Using a pre-training and post-training survey in the module, we measured self-reported PDMP use patterns and perceived PDMP value in specific clinical situations and compared pre- and post-training responses. Within the module, we presented three fictional pain cases and asked participants how they would manage each, both before, and then after presenting prescription drug history simulating a PDMP report. We measured changes in the fictional case treatment plans before and after seeing prescription history. Finally, we measured and compared how often each participant accessed the Maryland PDMP database before and after completing the educational module. We used multivariate logistic regression to measure the effect of the intervention on actual PDMP use frequency.

Results

One hundred and fifty participants enrolled and completed the training module, and we successfully retrieved real-world PDMP use data of 137 of them. Participants’ decisions to prescribe opioids changed significantly after reviewing PDMP data in each of the fictional cases provided in the module. In the months following the training, the rate of PDMP use increased by a median of four use-cases per month among providers in practice for less than 20 years (p = 0.039) and two use-cases per month among infrequent opioid prescribers (p = 0.014).

Conclusion

A brief online case-based educational intervention was associated with a significant increase in the rate of PDMP use among infrequent opioid prescribers and those in practice less than 20 years.

Comparing Hospital and Primary Care Physicians' Attitudes and Knowledge Regarding Antibiotic Prescribing: A Survey within the Centre Region of Portugal

BACKGROUND

Antibiotic resistance is a worldwide public health problem, leading to longer hospital stays, raising medical costs and mortality levels. As physicians' attitudes are key factors to antibiotic prescribing, this study sought to explore their differences between primary care and hospital settings.

METHODS

A survey was conducted between September 2011 and February 2012 in the center region of Portugal in the form of a questionnaire to compare hospital (n = 154) and primary care (n = 421) physicians' attitudes and knowledge regarding antibiotic prescribing.

RESULTS

More than 70% of the attitudes were statistically different (p < 0.05) between hospital physicians (HPs) and primary care physicians (PCPs). When compared to PCPs, HPs showed higher agreement with antibiotic resistances being a public health problem and ascribed more importance to microbiological tests and to the influence of prescription on the development of resistances. On the other hand, PCPs tended to agree more regarding the negative impact of self-medication with antibiotics dispensed without medical prescription and the need for rapid diagnostic tests. Seven out of nine sources of knowledge's usefulness were statistically different between both settings, with HPs considering most of the knowledge sources to be more useful than PCPs.

CONCLUSIONS

Besides the efforts made to improve both antibiotic prescribing and use, there are differences in the opinions between physicians working in different settings that might impact the quality of antibiotic prescribing. In the future, these differences must be considered to develop more appropriate interventions.

Information technology interventions to improve antibiotic prescribing for patients with acute respiratory infection: a systematic review

OBJECTIVES

Information technology (IT) interventions provide physicians with easy and quick access to information at the point of care and can play a major role in clinical decision-making for antibiotic prescribing. This study aimed to examine the effects and characteristics of IT interventions on improving antibiotic prescribing for patients with acute respiratory infection (ARI).

METHODS

A comprehensive search was performed in Medline (through PubMed), ISI web of science, Embase, and Cochrane databases from inception to 31 August 2020. Randomized controlled trial (RCT) and cluster RCT (CRCT) studies examining the effectiveness of IT interventions in improving antibiotic prescribing for patients with ARI were included. Participants were patients with ARI. IT interventions were used for improving antibiotic prescribing. Two researchers independently extracted data from studies on methods, characteristics of interventions, and results. The characteristics of interventions were extracted based on three dimensions of IT design, data entry source, and implementation characteristics.

RESULTS

Eighteen studies (15 CRCTs and three RCTs) were included. Most of included studies (n = 11) were conducted in the United States. In 12 studies (66.7%), IT interventions improved the level of antibiotic prescribing, and in eight of the 12 studies the effect was statistically significant. In two studies the intervention had a statistically significant negative effect, and in two studies the level of antibiotic prescribing was not changed. Seventeen studies (94.4%) used clinical decision support systems (CDSSs) for the intervention. In 12 studies (66.7%) CDSSs were integrated with electronic health records (EHRs).

CONCLUSIONS

Information technology interventions have the potential to improve prescription of antibiotics for patients with acute respiratory infection and to change physicians' behaviours in this regard. Factors affecting the acceptance of IT-based interventions to improve prescription of antibiotics should be investigated in future studies.

Following the Script: An Exploratory Study of the Therapeutic Reasoning Underlying Physicians' Choice of Antimicrobial Therapy

PURPOSE

Physicians frequently prescribe antimicrobials inappropriately, leading to an increase in the rate of resistance, which in turn, harms patients. To better understand why physicians prescribe specific antimicrobials in particular cases, the authors investigated the decision-making processes underlying physicians' antimicrobial choice (i.e., their antimicrobial reasoning).

METHOD

Applying a clinical reasoning framework, the authors conducted semi-structured, qualitative interviews with a purposive sample of attending physicians in infectious diseases and hospital medicine at 2 hospitals in fall 2018. An interviewer asked participants to describe how they would choose which antimicrobial to prescribe in 3 clinical vignettes, to recall how they chose an antimicrobial in an example from their own practice, and to indicate their steps in antimicrobial selection generally. The authors identified steps and factors in antimicrobial reasoning through thematic analysis of interviews and the note cards that participants used to delineate their general antimicrobial reasoning processes.

RESULTS

Sixteen participants described 3 steps in the antimicrobial reasoning process: naming the syndrome, delineating pathogens, and selecting the antimicrobial (therapy script). They mentioned 25 different factors in their reasoning processes, which the authors grouped into 4 areas: preexisting patient characteristics, current case features, provider and health care system factors, and treatment principles. Participants used antimicrobial (therapy) scripts that included 14 different drug characteristics. The authors present the steps and factors in a framework for antimicrobial reasoning.

CONCLUSIONS

Through this exploratory study, the authors identified steps and factors involved in physicians' antimicrobial reasoning process, as well as the content of their antimicrobial (therapy) scripts. They organized all these findings into a framework for antimicrobial decision making. This information may ultimately be adapted into educational tools to improve antimicrobial prescribing across the spectrum of learners and practicing physicians.

Practice variation and practice guidelines: Attitudes of generalist and specialist physicians, nurse practitioners, and physician assistants

Objective

To understand clinicians' beliefs about practice variation and how variation might be reduced.

Methods

We surveyed board-certified physicians (N = 178), nurse practitioners (N = 60), and physician assistants (N = 12) at an academic medical center and two community clinics, representing family medicine, general internal medicine, and cardiology, from February—April 2016. The Internet-based questionnaire ascertained clinicians' beliefs regarding practice variation, clinical practice guidelines, and costs.

Results

Respondents agreed that practice variation should be reduced (mean [SD] 4.5 [1.1]; 1 = strongly disagree, 6 = strongly agree), but agreed less strongly (4.1 [1.0]) that it can realistically be reduced. They moderately agreed that variation is justified by situational differences (3.9 [1.2]). They strongly agreed (5.2 [0.8]) that clinicians should help reduce healthcare costs, but agreed less strongly (4.4 [1.1]) that reducing practice variation would reduce costs. Nearly all respondents (234/249 [94%]) currently depend on practice guidelines. Clinicians rated differences in clinician style and experience as most influencing practice variation, and inaccessibility of guidelines as least influential. Time to apply standards, and patient decision aids, were rated most likely to help standardize practice. Nurse practitioners and physicians assistants (vs physicians) and less experienced (vs senior) clinicians rated more favorably several factors that might help to standardize practice. Differences by specialty and academic vs community practice were small.

Conclusions

Clinicians believe that practice variation should be reduced, but are less certain that this can be achieved. Accessibility of guidelines is not a significant barrier to practice standardization, whereas more time to apply standards is viewed as potentially helpful.

Categorical Risk Perception Drives Variability in Antibiotic Prescribing in the Emergency Department: A Mixed Methods Observational Study

BACKGROUND

Adherence to evidence-based antibiotic therapy guidelines for treatment of upper respiratory tract infections (URIs) varies widely among clinicians. Understanding this variability is key for reducing inappropriate prescribing.

OBJECTIVE

To measure how emergency department (ED) clinicians' perceptions of antibiotic prescribing risks affect their decision-making.

DESIGN

Clinician survey based on fuzzy-trace theory, a theory of medical decision-making, combined with retrospective data on prescribing outcomes for URI/pneumonia visits in two EDs. The survey predicts the categorical meanings, or gists, that individuals derive from given information.

PARTICIPANTS

ED physicians, residents, and physician assistants (PAs) who completed surveys and treated patients with URI/pneumonia diagnoses between August 2014 and December 2015.

MAIN MEASURES

Gists derived from survey responses and their association with rates of antibiotic prescribing per visit.

KEY RESULTS

Of 4474 URI/pneumonia visits, 2874 (64.2%) had an antibiotic prescription. However, prescribing rates varied from 7% to 91% for the 69 clinicians surveyed (65.2% response rate). Clinicians who framed therapy-prescribing decisions as a categorical choice between continued illness and possibly beneficial treatment ("why not take a risk?" gist, which assumes antibiotic therapy is essentially harmless) had higher rates of prescribing (OR 1.28 [95% CI, 1.06-1.54]). Greater agreement with the "antibiotics may be harmful" gist was associated with lower prescribing rates (OR 0.81 [95% CI, 0.67-0.98]).

CONCLUSIONS

Our results indicate that clinicians who perceive prescribing as a categorical choice between patients remaining ill or possibly improving from therapy are more likely to prescribe antibiotics. However, this strategy assumes that antibiotics are essentially harmless. Clinicians who framed decision-making as a choice between potential harms from therapy and continued patient illness (e.g., increased appreciation of potential harms) had lower prescribing rates. These results suggest that interventions to reduce inappropriate prescribing should emphasize the non-negligible possibility of serious side effects.

Decision support during electronic prescription to stem antibiotic overuse for acute respiratory infections: a long-term, quasi-experimental study

BACKGROUND

Interventions to support decision-making can reduce inappropriate antibiotic use for acute respiratory infections (ARI), but they may not be sustainable. The objective of the study is to evaluate the long-term effectiveness of a clinical decision-support system (CDSS) interposed at the time of electronic (e-) prescriptions for selected antibiotics.

METHODS

This is a retrospective, observational intervention study, conducted within a large, statewide Veterans Affairs health system. Participants are outpatients with an initial visit for ARI. A CDSS was deployed upon e-prescription of selected antibiotics during the study period. From 01/2004 to 05/2006 (pre-withdrawal period), the CDSS targeted azithromycin and the fluoroquinolone gatifloxacin. From 05/2006 to 12/2011 (post-withdrawal period), the CDSS was retained for azithromycin but withdrawn for the fluoroquinolone. A manual record review was conducted to determine concordance of antibiotic prescription with ARI treatment guidelines.

RESULTS

Of 1131 included ARI visits, 380 (33.6%) were guideline-concordant. For azithromycin, concordance did not change between the pre- and post-withdrawal periods, and adjusted odds of concordance was 8.8 for the full study period, compared to unrestricted antibiotics. For fluoroquinolones, guideline concordance decreased from 88.6% (39 of 44 visits) to 51.3% (59 of 115 visits), pre- vs. post-withdrawal periods (p < 0.005). The adjusted odds of concordance compared to "All Other Antibiotics" visits decreased from 24.4 (95% CI 9.0-66.3) pre-withdrawal to 5.5 (95% CI 3.5-8.8) post-withdrawal (p = .008). Concordance did not change between those same time periods for antibiotics that were never subjected to the intervention ("All Other Antibiotics").

CONCLUSIONS

A CDSS interposed at the time of e-prescription of selected antibiotics can shift their use toward ARI treatment guidelines, and this effect can be maintained over the long term as long as the CDSS remains in place. Removal of the CDSS after 3.5 years of implementation resulted in a rise in guideline-discordant antibiotic use.

What Drives Variation in Antibiotic Prescribing for Acute Respiratory Infections?

BACKGROUND

Acute respiratory infections are the most common symptomatic reason for seeking care among patients in the US, and account for the majority of all antibiotic prescribing, yet a large fraction of antibiotic prescriptions are inappropriate.

OBJECTIVE

We sought to identify the underlying factors driving variation in antibiotic prescribing across clinicians and settings.

DESIGN, PARTICIPANTS

Using electronic health data for adult ambulatory visits for acute respiratory infections to a retail clinic chain and primary care practices from an integrated healthcare system, we identified a random sample of clinicians for survey.

MAIN MEASURES

We evaluated independent predictors of overall prescribing and imperfect antibiotic prescribing, controlling for clinician and site of care. We defined imperfect antibiotic prescribing as prescribing for non-antibiotic-appropriate diagnoses, failure to prescribe for an antibiotic-appropriate diagnosis, or prescribing a non-guideline-concordant antibiotic.

KEY RESULTS

Response rates were 34 % for retail clinics and 24 % for physicians' offices (N = 187). Clinicians in physicians' offices prescribed antibiotics less often than those in retail clinics (53 % versus 67 %; p < 0.01), but had a higher imperfect antibiotic prescribing rate (65 % versus 31 %; p < 0.01). Feeling rushed was associated with higher antibiotic prescribing (OR 1.34; 95 % CI 1.03, 1.75). Antibiotic prescribing was also associated with clinician disagreement that antibiotics are overused (OR 1.60, 95 % CI, 1.16, 2.20). Imperfect antibiotic prescribing was associated with receiving antibiotic prescribing feedback (OR 1.35, 95 % CI 1.04, 1.75) and disagreement that patient demand was a problem (OR 1.66, 95 % CI 1.00, 2.73). Imperfect antibiotic prescribing was less common with clinicians who perceived that they prescribed antibiotics less often than their peers (OR 0.63, 95 % CI 0.46, 0.87).

CONCLUSIONS

Poor-quality antibiotic prescribing was associated with feeling rushed, believing less strongly that antibiotics were overused, and believing that patient demand was not an issue, factors that can be assessed and addressed in future interventions.

Effects of knowledge, attitudes, and practices of primary care providers on antibiotic selection, United States

Primary care providers were familiar with recommendations for antibiotic drug selection for common infections, but do not always comply with them.

Appropriate selection of antibiotic drugs is critical to optimize treatment of infections and limit the spread of antibiotic resistance. To better inform public health efforts to improve prescribing of antibiotic drugs, we conducted in-depth interviews with 36 primary care providers in the United States (physicians, nurse practitioners, and physician assistants) to explore knowledge, attitudes, and self-reported practices regarding antibiotic drug resistance and antibiotic drug selection for common infections. Participants were generally familiar with guideline recommendations for antibiotic drug selection for common infections, but did not always comply with them. Reasons for nonadherence included the belief that nonrecommended agents are more likely to cure an infection, concern for patient or parent satisfaction, and fear of infectious complications. Providers inconsistently defined broad- and narrow-spectrum antibiotic agents. There was widespread concern for antibiotic resistance; however, it was not commonly considered when selecting therapy. Strategies to encourage use of first-line agents are needed in addition to limiting unnecessary prescribing of antibiotic drugs.

Evaluating Guideline-Recommended Antibiotic Practices for Childhood Respiratory Infections: Is It Time to Consider Case-Based Formats?

OBJECTIVE

We sought to better understand barriers to adherence to published guidelines for respiratory infections among community providers.

METHODS

A case-based survey was developed and emailed to all members of the state pediatric society. Providers chose their preferred management for acute otitis media, acute bacterial sinusitis, and community-acquired pneumonia. An "answer key" and a follow-up questionnaire were distributed to assess reevaluation of current practices.

RESULTS

We received 173 completed surveys (15% response rate). While most responders followed guideline recommendations (6 of the 10 questions with ≥ 65% choosing recommended antibiotic), discrepancies existed in several cases. After receiving the answer key, respondents said they reviewed the guidelines (69%), adjusted their practice (26%), used cases for teaching (9%), and discussed guidelines with colleagues (21%).

CONCLUSIONS

The majority of respondents followed published guidelines, but there was a tendency to overuse azithromycin in certain cases. Future guidelines including case-based discussions may enhance adherence.

Association Between Outpatient Antibiotic Prescribing Practices and Community-Associated Clostridium difficile Infection

A modest, 10% reduction in outpatient antibiotic prescribing among U.S. adults could result in a substantial 17% reduction in Clostridium difficile infections that originate in the community.

Background. Antibiotic use predisposes patients to Clostridium difficile infections (CDI), and approximately 32% of these infections are community-associated (CA) CDI. The population-level impact of antibiotic use on adult CA-CDI rates is not well described.

Methods. We used 2011 active population- and laboratory-based surveillance data from 9 US geographic locations to identify adult CA-CDI cases, defined as C difficile-positive stool specimens (by toxin or molecular assay) collected from outpatients or from patients ≤3 days after hospital admission. All patients were surveillance area residents and aged ≥20 years with no positive test ≤8 weeks prior and no overnight stay in a healthcare facility ≤12 weeks prior. Outpatient oral antibiotic prescriptions dispensed in 2010 were obtained from the IMS Health Xponent database. Regression models examined the association between outpatient antibiotic prescribing and adult CA-CDI rates.

Methods. Healthcare providers prescribed 5.2 million courses of antibiotics among adults in the surveillance population in 2010, for an average of 0.73 per person. Across surveillance sites, antibiotic prescription rates (0.50–0.88 prescriptions per capita) and unadjusted CA-CDI rates (40.7–139.3 cases per 100 000 persons) varied. In regression modeling, reducing antibiotic prescribing rates by 10% among persons ≥20 years old was associated with a 17% (95% confidence interval, 6.0%–26.3%; P = .032) decrease in CA-CDI rates after adjusting for age, gender, race, and type of diagnostic assay. Reductions in prescribing penicillins and amoxicillin/clavulanic acid were associated with the greatest decreases in CA-CDI rates.

Conclusions and Relevance. Community-associated CDI prevention should include reducing unnecessary outpatient antibiotic use. A modest reduction of 10% in outpatient antibiotic prescribing can have a disproportionate impact on reducing CA-CDI rates.

Community-acquired pneumonia: why aren't national antibiotic guidelines followed?

AIMS

Adherence to guidelines for the management of community-acquired pneumonia (CAP) has been shown to improve patients' clinical outcomes. This study aimed to assess adherence to the Australian Therapeutic Guidelines (TG14) for the empirical management of CAP, and explore the potential barriers affecting adherence to these guidelines.

METHODS

Medical records were reviewed for all patients who were diagnosed with CAP within 24 h of presentation at the Royal Hobart Hospital, the main teaching hospital in Tasmania, Australia, between July 2010 and March 2011. A survey of emergency department and medical team prescribers was also undertaken to identify potential barriers to adhere with the guidelines. χ(2) and Fisher's exact tests were used to test the significance between categorical data. To compare categorical and scale data, the Mann-Whitney U-test was used.

RESULTS

A total of 193 patient records were assessed. The overall adherence to TG14 for the empirical antibiotic management of CAP was 16.1% (3.1%, 20.7% and 25.4% for patients with mild, moderate and severe CAP, respectively). Ceftriaxone was prescribed to 34.4%, 26.8% and 57.4% of patients with mild, moderate and severe CAP, respectively. The response rate to the barrier survey was 43.1%; of those who responded, 46.4% thought the influence of senior doctors on junior doctors could be a factor affecting adherence to the guidelines. Other barriers noted were a lack of guideline awareness (39.3%), the requirement to calculate the severity of CAP (35.7%), and the existence of other guidelines that conflict with TG14 (28.6%).

CONCLUSIONS

Adherence to CAP treatment guidelines was poor, especially in patients with mild disease. Prescribing was mainly influenced by senior doctors. Efforts to improve compliance with CAP treatment guidelines should consider the potential barriers that hinder adherence.

Management of patients with sore throats in relation to guidelines: an interview study in Sweden

OBJECTIVE

To explore how a group of Swedish general practitioners (GPs) manage patients with a sore throat in relation to current guidelines as expressed in interviews.

DESIGN

Qualitative content analysis was used to analyse semi-structured interviews.

SETTING

Swedish primary care.

SUBJECTS

A strategic sample of 25 GPs.

MAIN OUTCOME MEASURES

Perceived management of sore throat patients.

RESULTS

It was found that nine of the interviewed GPs were adherent to current guidelines for sore throat and 16 were non-adherent. The two groups differed in terms of guideline knowledge, which was shared within the team for adherent GPs while idiosyncratic knowledge dominated for the non-adherent GPs. Adherent GPs had no or low concerns for bacterial infections and differential diagnosis whilst non-adherent GPs believed that in patients with a sore throat any bacterial infection should be identified and treated with antibiotics. Patient history and examination was mainly targeted by adherent GPs whilst for non-adherent GPs it was often redundant. Non-adherent GPs reported problems getting patients to abstain from antibiotics, whilst no such problems were reported in adherent GPs.

CONCLUSION

This interview study of sore throat management in a strategically sampled group of Swedish GPs showed that while two-thirds were non-adherent and had a liberal attitude to antibiotics one-third were guideline adherent with a restricted view on antibiotics. Non-adherent GPs revealed significant knowledge gaps. Adherent GPs had discussed guidelines within the primary care team while non-adherent GPs had not. Guideline implementation thus seemed to be promoted by knowledge shared in team discussions.

Leukocyte populations and C-reactive protein as predictors of bacterial infections in febrile outpatient children

Objective: Infections remain the major cause of unnecessary antibiotic use in pediatric outpatient settings. Complete blood count (CBC) is the essential test in the diagnosis of infections. C-reactive protein (CRP) is also useful for assessment of young children with serious bacterial infections. The purpose of the study was to evaluate leukocyte populations and CRP level to predict bacterial infections in febrile outpatient children.

Materials and Methods: The values of CBC by Cell-DYN 4000 autoanalyzer and serum CRP levels were evaluated in 120 febrile patients with documented infections (n:74 bacterial, n:46 viral) and 22 healthy controls.

Results: The mean CRP, neutrophil and immature granulocyte (IG) values were significantly higher in bacterial infections than in viral infections and controls (p<0.05). C-reactive protein was significantly correlated with neutrophil level in bacterial infections (r: 0.76, p<0.05). Specificity of IG was greatest at 93%, only a modest 56% for neutrophil and mild 18% for CRP, whereas 100% for combination of IG, neutrophil and CRP.

Conclusion: Acute bacterial infection seems to be very unlikely in children with normal leukocyte populations and CRP values, even if clinically signs and symptoms indicate acute bacterial infections.

Does a 30-min quality improvement clinical practice meeting reviewing the recommended Papanicolaou test guidelines for adolescents improve provider adherence to guidelines in a pediatric primary care office?

PURPOSE

The purpose of this quality improvement project was to evaluate adherence to Papanicolaou (Pap) test guidelines 6 months prior to and 6 months following a 30-min educational clinical practice meeting in a pediatric primary care office. Guidelines for Pap tests have been revised in recent years by the American Academy of Obstetrics and Gynecology, the American Cancer Society, and the U.S. Preventive Task Force, but providers often do not adhere to the guidelines.

DATA SOURCES

A total of 777 charts from a pediatric primary care office were reviewed. Eighty-four percent (652) met criteria for inclusion.

CONCLUSIONS

Among sexually active adolescents, there was a statistically significant relationship between rates of Pap tests following the clinical practice meeting (χ(2) (1) = 13.5, p = .001). Prior to the meeting there were 29 Pap tests recorded, whereas after there were two Pap tests done. After the focused clinical practice meeting, providers performed far fewer Pap tests, which is in accordance with the guidelines for this population.

IMPLICATIONS FOR PRACTICE

Providers may not always practice in accordance with recommended clinical practice guidelines for various reasons. Focused, in-office educational interventions via clinical practice meetings may be an effective way of discussing recommended guidelines to improve provider adherence.

Use of an electronic health record clinical decision support tool to improve antibiotic prescribing for acute respiratory infections: the ABX-TRIP study

BACKGROUND

Antibiotics are often inappropriately prescribed for acute respiratory infections (ARIs).

OBJECTIVE

To assess the impact of a clinical decision support system (CDSS) on antibiotic prescribing for ARIs.

DESIGN

A two-phase, 27-month demonstration project.

SETTING

Nine primary care practices in PPRNet, a practice-based research network whose members use a common electronic health record (EHR).

PARTICIPANTS

Thirty-nine providers were included in the project.

INTERVENTION

A CDSS was designed as an EHR progress note template. To facilitate CDSS implementation, each practice participated in two to three site visits, sent representatives to two project meetings, and received quarterly performance reports on antibiotic prescribing for ARIs.

MAIN OUTCOME MEASURES

1) Use of antibiotics for inappropriate indications. 2) Use of broad spectrum antibiotics when inappropriate. 3) Use of antibiotics for sinusitis and bronchitis.

KEY RESULTS

The CDSS was used 38,592 times during the 27-month intervention; its use was sustained for the study duration. Use of antibiotics for encounters at which diagnoses for which antibiotics are rarely appropriate did not significantly change through the course of the study (estimated 27-month change, 1.57% [95% CI, -5.35%, 8.49%] in adults and -1.89% [95% CI, -9.03%, 5.26%] in children). However, use of broad spectrum antibiotics for ARI encounters improved significantly (estimated 27 month change, -16.30%, [95% CI, -24.81%, -7.79%] in adults and -16.30 [95%CI, -23.29%, -9.31%] in children). Prescribing for bronchitis did not change significantly, but use of broad spectrum antibiotics for sinusitis declined.

CONCLUSIONS

This multi-method intervention appears to have had a sustained impact on reducing the use of broad spectrum antibiotics for ARIs. This intervention shows promise for promoting judicious antibiotic use in primary care.

Physicians' discussions about body weight, healthy diet, and physical activity with overweight or obese elderly patients

OBJECTIVE

To investigate the correlates of physician-patient discussions about body weight, healthy diet, and physical activity.

METHOD

Subjects were 635 adults (≥65 years; mean 72.8 years) who had an increased body mass index (BMI≥25 kg/m2) and participated in a self-administered community survey. Logistic regression analyses were performed.

RESULTS

While approximately half of study participants reported having discussed healthy diets (51%) and physical activity (52%) with their physician, only 42% of those who were overweight or obese reported being recognized as such by their physician. Being moderately or severely obese, more chronic conditions, and more frequent physician visits increased the likelihood of being recognized as overweight or obese and reporting lifestyle discussions.

DISCUSSION

The health care provider is important in recognizing older patient's weight problems and discussing practical lifestyle changes. Tools for more proactive screening and implementation of follow-up behavioral counseling can help the health care providers better address obesity prevention in clinical practice.
