The effect of a physician-targeted intervention on metoclopramide prescribing practice.

ABSTRACT: BACKGROUND:Metoclopramide use is associated with serious and potentially irreversible neurologic side effects. However, it is often used for questionable or unclear indications in clinical practice. OBJECTIVES:To (1) determine whether an intervention targeted at the prescribing physician would increase the rate of metoclopramide discontinuation among patients prescribed the medication for questionable or unclear indications; and (2) assess the durability of the discontinuation. STUDY DESIGN:A randomized controlled trial. SETTING:Ambulatory practices of a quaternary care medical center. PARTICIPANTS:Ambulatory, electronic medical record-utilizing clinicians of the quaternary medical center. INTERVENTION:A letter regarding participating clinicians' prescription(s) of metoclopramide for patients with questionable or unclear indications. MAIN OUTCOME MEASURES:The rate and the durability of metoclopramide discontinuation. RESULTS:Fourteen of 31 (45%) patients of intervention group clinicians and 10 of 30 (33%) patients of nonintervention group clinicians had metoclopramide discontinued within 12 weeks, yielding a risk ratio for metoclopramide discontinuation of 1.4 (95% confidence interval [CI] 0.6-3.0) in the intervention versus nonintervention group. Of the 29 patients who had their metoclopramide discontinued during the study, 26 (90%, 95% CI 73%-98%) still had no active metoclopramide prescription in the subsequent 6 months. No adverse events were detected during the follow-up period. CONCLUSION:A physician-targeted intervention letter did not lead to a statistically significantly increased rate of metoclopramide discontinuation among patients who had questionable or unclear indications for the medication. Discontinuation of metoclopramide therapy for questionable or unclear indications was durable in most patients.

Project description:IntroductionManagement of prescription medicines is challenging for older patients due to frail health and the prevalence of multiple chronic conditions. A salient policy challenge of prescribing practices is that all physicians are not well informed about the national clinical guidelines. A feasible policy intervention to mitigate the harms caused by Potentially Inappropriate Medications is to influence the frequency of prescribing and other prescribing attributes of the drugs by providing accurate and up-to-date information about the national clinical guidelines.ObjectivesThe objective of this study was to examine the effect of a nationwide information intervention on physicians' prescribing practices and patients' healthcare utilization.MethodsWe used a quasi-experimental research design based on difference-in-differences variation and nationwide register data on prescribers and purchasers of pregabalin, nortriptyline, and amitriptyline combinations in Finland between January 2018 and May 2019. The study included 68,914 patients and 11,432 physicians.ResultsWe found that the information letter sent to all prescribers of pregabalin, nortriptyline, or amitriptyline combinations to patients aged 75 years or older decreased the probability of prescribing of these medications. The estimated effect of - 3.3 percentage points (95% confidence interval [- 0.041, - 0.024]) corresponds to a 29% reduction compared to the baseline mean of the outcome. The filled quantity, measured in Defined Daily Doses, of pregabalin, nortriptyline, and amitriptyline combinations per month was reduced by 11.7% [- 14.5% to - 8.9%] among patients aged 75 years or older. No effect on patients' healthcare utilization was observed.ConclusionsFindings of the study suggest that personal information intervention was an effective policy tool for nudging physicians to reduce prescribing of potentially inappropriate medicines, whereas the reduction in prescribing was not accompanied by improvements or adverse effects in patients' health.

Project description:BackgroundInterventions designed to narrow the gap between research findings and clinical practice may be effective, but also costly. Economic evaluations are necessary to judge whether such interventions are worth the effort. We have evaluated the economic effects of a tailored intervention to support the implementation of guidelines for the use of antihypertensive and cholesterol-lowering drugs. The tailored intervention was evaluated in a randomized trial, and was shown to significantly increase the use of thiazides for patients started on antihypertensive medication, but had little or no impact on other outcomes. The increased use of thiazides was not expected to have an impact on health outcomes.Methods and findingsWe performed cost-minimization and cost-effectiveness analyses on data from a randomized trial involving 146 general practices from two geographical areas in Norway. Each practice was randomized to either the tailored intervention (70 practices; 257 physicians) or control group (69 practices; 244 physicians). Only patients that were being started on antihypertensive medication were included in the analyses. A multifaceted intervention was tailored to address identified barriers to change. Key components were an educational outreach visit with audit and feedback, and computerized reminders. Pharmacists conducted the visits. A cost-minimization framework was adopted, where the costs of intervention were set against the reduced treatment costs (principally due to increased use of thiazides rather than more expensive medication). The cost-effectiveness of the intervention was estimated as the cost per additional patient being started on thiazides. The net annual cost (cost minimization) in our study population was 53,395 US dollars, corresponding to 763 US dollars per practice. The cost per additional patient started on thiazides (cost-effectiveness) was 454 US dollars. The net annual savings in a national program was modeled to be 761,998 US dollars, or 540 US dollars per practice after 2 y. In this scenario the savings exceeded the costs in all but two of the sensitivity analyses we conducted, and the cost-effectiveness was estimated to be 183 US dollars.ConclusionsWe found a significant shift in prescribing of antihypertensive drugs towards the use of thiazides in our trial. A major reason to promote the use of thiazides is their lower price compared to other drugs. The cost of the intervention was more than twice the savings within the time frame of our study. However, we predict modest savings over a 2-y period.

Project description:BackgroundPhysician characteristics and perceptions and their effect on choice of therapies for patients with thyroid cancer have been well studied. Some data also exist about physician characteristics and prescribing treatment for subclinical hypothyroidism. The effect of physician characteristics on prescribing thyroid preparations for treating overt hypothyroidism is less studied.MethodsMembers of the American Thyroid Association were surveyed in 2017. Physicians were presented with 13 different theoretical patients with hypothyroidism and asked to choose among six therapeutic options, including levothyroxine, synthetic combination therapy, thyroid extract, and liothyronine monotherapy. The 13 patient scenarios incorporated parameters that potentially provide reasons for considering combination therapy (presence of symptoms, low serum triiodothyronine concentration, and documentation of deiodinase polymorphisms). Repeated-measures logistic regression analysis was performed to examine the prescribing of the various therapies. Data regarding the responding physicians were also collected. These data included number of years in practice, country of practice, and specialty. Multivariate repeated-measures logistic regression analysis of prescribing patterns was also conducted controlling for all patient and physician characteristics.ResultsOf the 389 survey respondents, 93% prescribed therapy for hypothyroidism. Fifty-three percent of respondents had been in practice for >20 years, and 23% had been in practice for 11-20 years. Sixty-four percent practiced in North America, and 18% practiced in Europe. Eight-six percent were endocrinologists, and 5% were surgeons. In multivariate analysis, physicians from North America were both more likely to prescribe any triiodothyronine-containing therapies (odds ratio [OR] = 1.8 [confidence interval (CI) 1.3-2.4]) and more likely to add liothyronine to levothyroxine therapy (OR = 1.9 [CI 1.2-2.9]). In addition, they were more likely to prescribe desiccated thyroid extract or liothyronine monotherapy (OR = 1.7 [CI 1.0-2.9]).ConclusionsA previous analysis of this survey showed that patient characteristics profoundly affect physician prescribing patterns. The current multivariate analysis shows that physician characteristics affect prescribing patterns. Whether this is due to impact upon physicians of patient-related experiences, media exposure, influence from pharmaceutical companies, educational activities, or other concerns cannot be determined. However, these results have potential importance for understanding physician-patient interactions at a time when the benefits and risks of triiodothyronine-containing therapies have not been fully documented.

Project description:BackgroundClinical vignettes have been used widely to compare quality of clinical care and to assess variation in practice, but the effect of different response formats has not been extensively evaluated. Our objective was to compare three clinical vignette-based survey response formats - open-ended questionnaire (A), closed-ended (multiple-choice) questionnaire with deceptive response items mixed with correct items (B), and closed-ended questionnaire with only correct items (C) - in rheumatologists' pre-treatment assessment for tumor-necrosis-factor (TNF) blocker therapy.MethodsStudy designProspective randomized study.SettingRheumatologists attending the 2004 French Society of Rheumatology meeting. Physicians were given a vignette describing the history of a fictitious woman with active rheumatoid arthritis, who was a candidate for therapy with TNF blocking agents, and then were randomized to receive questionnaire A, B, or C, each containing the same four questions but with different response formats, that asked about their pretreatment assessment.MeasurementsLong (recommended items) and short (mandatory items) checklists were developed for pretreatment assessment for TNF-blocker therapy, and scores were expressed on the basis of responses to questionnaires A, B, and C as the percentage of respondents correctly choosing explicit items on these checklists.Statistical analysisComparison of the selected items using pairwise Chi-square tests with Bonferonni correction for variables with statistically significant differences.ResultsData for all surveys distributed (114 As, 118 Bs, and 118 Cs) were complete and available for analysis. The percentage of questionnaire A, B, and C respondents for whom data was correctly complete for the short checklist was 50.4%, 84.0% and 95.0%, respectively, and was 0%, 5.0% and 5.9%, respectively, for the long version. As an example, 65.8%, 85.7% and 95.8% of the respondents of A, B, and C questionnaires, respectively, correctly identified the need for tuberculin skin test (p < 0.0001).ConclusionIn evaluating clinical practice with use of a clinical vignette, a multiple-choice format rather than an open-ended format overestimates physician performance. The insertion of deceptive response items mixed with correct items in closed-ended (multiple-choice) questionnaire failed to avoid this overestimation.

Project description:ImportanceThe frequency of use of endovenous thermal ablation (EVTA) to treat chronic venous insufficiency has increased rapidly in the US. Wide variability in EVTA use among physicians has been documented, and standard EVTA rates were defined in the 2017 Medicare database.ObjectiveTo assess whether providing individualized physician performance reports is associated with reduced variability in EVTA use and cost savings.Design, setting, and participantsThis prospective quality improvement study used data from all US Medicare patients aged 18 years or older who underwent at least 1 EVTA between January 1, 2017, and December 31, 2017, and between January 1, 2019, and December 31, 2019. All US physicians who performed at least 11 EVTAs yearly for Medicare patients in 2017 and 2019 were included in the assessment.InterventionA performance report comprising individual physician EVTA use per patient with peer-benchmarking data was distributed to all physicians in November 2018.Main outcomes and measuresThe mean number of EVTAs performed per patient was calculated for each physician. Physicians who performed 3.4 or more EVTA procedures per patient per year were considered outliers. The change in the number of procedures from 2017 to 2019 was analyzed overall and by inlier and outlier status. An economic analysis was also performed to estimate the cost savings associated with the intervention.ResultsA total of 188 976 patients (102 222 in 2017 and 86 754 in 2019) who had an EVTA performed by 1558 physicians were included in the analysis. The median patient age was 72.2 years (IQR, 67.9-77.8 years); 67.3% of patients were female, and 84.9% were White. Among all physicians, the mean (SD) number of EVTAs per patient decreased from 2017 to 2019 (1.97 [0.85] vs 1.89 [0.77]; P < .001). There was a modest decrease in the mean number of EVTAs per patient among inlier physicians (1.83 [0.57] vs 1.78 [0.55]; P < .001) and a more substantial decrease among outlier physicians (4.40 [1.01] vs 3.67 [1.41] ; P < .001). Outliers in 2017 consisted of 90 physicians, of whom 71 (78.9%) reduced their EVTA use after the intervention. The number of EVTAs per patient decreased by a mean (SD) of 0.09 (0.46) procedures overall (median, 0.10 procedures [IQR, -0.10 to 0.30 procedures]; P < .001). The estimated cost savings associated with the decrease was $6.3 million in 2019.Conclusions and relevanceIn this quality improvement study, substantial variability in the number of EVTAs performed per patient was observed across the US. When physicians were provided with a 1-time peer-benchmarked performance report card, the timing of the intervention was associated with a significant decrease in the number of EVTAs performed per patient, particularly among outlier physicians. This quality improvement initiative was associated with reduced variability in EVTA use in the US and a substantial savings for Medicare.

Project description:Studies have demonstrated that physician/pharmacist collaboration can improve management of chronic conditions.The purpose of this study was to determine whether a correlation exists between existing clinical pharmacy services within a practice-based research network (PBRN) and provider attitudes and beliefs regarding implementing a new pharmacy intervention based on the Theory of Planned Behavior (TPB).A validated survey was completed by one clinical pharmacist from each office. This instrument evaluated the current clinical pharmacy services provided in the medical office. TPB instruments were developed that measured beliefs concerning implementation of a clinical pharmacy intervention for either blood pressure or asthma. The pharmacy services and TPB surveys were then administered to physicians and pharmacists in 32 primary care offices throughout the United States.Physicians returned 321 (35.9%) surveys, while pharmacists returned 40 (75.5%). The Cronbach's alpha coefficients generally ranged from 0.65 to 0.98. TPB subscale scores were lower in offices rated with lower pharmacy service scores, but these differences were not statistically significant. There was no correlation between clinical pharmacy service score and providers' TPB subscale scores. In both the hypertension and asthma groups, pharmacists scores were significantly higher than physicians' scores on the attitudes subscale in the multivariate analysis (P < 0.001 and P < 0.05, respectively).Pharmacists consistently scored higher than physicians on the TPB, indicating that they felt the hypertension or asthma intervention would be more straightforward for them to implement than did physicians. There was no significant correlation between clinical pharmacy service scores and attitudes toward implementing a future physician/pharmacist collaborative intervention using the TPB. Future studies should investigate the ability of the TPB instrument to predict implementation of a similar intervention in offices of physicians never exposed to clinical pharmacy services.

Project description:BackgroundOur previous study demonstrated that pediatricians prescribe antibiotics without proper clinical justification to patients with enterovirus infection, although antibiotics are not effective in treating the infections caused by these viruses. To improve the quality of healthcare, we aim to evaluate the association of clinical and demographic characteristics of patients and further to identify the determining factors for prescribing antibiotics to children experiencing enterovirus infection.MethodsWe retrospectively reviewed the medical records of children who were hospitalized between January 2008 and December 2016 with a diagnosis of herpangina or hand-foot-mouth disease (HFMD). We identified those children who were prescribed antibiotics for at least 24 hours during admission. We conducted a retrospective descriptive study to analyze data in order to determine the factors associated with pediatrician antibiotics prescribing for enterovirus infection.ResultsIn the nine years of study period, the rate of antibiotics use was about 13% in these patients. A total of 3659 patients were enrolled during 2008~2012 and analyzed in detail. Elevated levels of C-reactive protein (CRP) and presence of leukocytosis in blood (WBC) were both significantly associated with pediatrician antibiotic prescribing for enterovirus infection (p<0.001). Between different specialistic devisions, there was significantly different proportion of antibiotics utilization for patients. In further analysis of antibiotics prescribing by Receiver operating characteristic (ROC) curve method, the level of CRP significantly had more the area under curve (0.708) compared with the count of WBC (p<0.05).ConclusionsThe present study indicates that higher serum level of CRP is strongly associated with pediatricians prescribing antibiotics for children experiencing herpangina or HFMD. Antibiotic prescribing is a complex process. Pediatricians should be more judicious in decision-making time by their specialistics. Our findings would shed new light on process and allay the concern about inappropriate antibiotics.
