Long-term effect of a practice-based intervention (HAPPY AUDIT) aimed at reducing antibiotic prescribing in patients with respiratory tract infections.

Objectives: Few studies have evaluated the long-term effects of educational interventions on antibiotic prescription and the results are controversial. This study was aimed at assessing the effect of a multifaceted practice-based intervention carried out 6 years earlier on current antibiotic prescription for respiratory tract infections (RTIs). Methods: The 210 general practitioners (GPs) who completed the first two registrations in 2008 and 2009 were invited to participate in a third registration. The intervention held before the second registration consisted of discussion about the first registration of results, appropriate use of antibiotics for RTIs, patient brochures, a workshop and the provision of rapid tests. As in the previous registrations, GPs were instructed to complete a template for all the patients with RTIs during 15 working days in 2015. A new group of GPs from the same areas was also invited to participate and acted as controls. A multilevel logistic regression analysis was performed considering the prescription of antibiotics as the dependent variable. Results: A total of 121 GPs included in the 2009 intervention (57.6%) and 117 control GPs registered 22 247 RTIs. On adjustment for covariables, compared with the antibiotic prescription observed just after the intervention, GPs assigned to intervention prescribed slightly more antibiotics 6 years later albeit without statistically significant differences (OR 1.08, 95% CI 0.89-1.31, P = 0.46), while GPs in the control group prescribed significantly more antibiotics (OR 2.74, 95% CI 2.09-3.59, P < 0.001). Conclusions: This study shows that a single multifaceted intervention continues to reduce antibiotic prescribing 6 years later.

Effectiveness of two types of intervention on antibiotic prescribing in respiratory tract infections in Primary Care in Spain. Happy Audit Study.

OBJECTIVE: To evaluate the effectiveness of two types of intervention in reducing antibiotic prescribing in respiratory tract infections (RTI). DESIGN: Before-after audit-based study. SETTING: Primary Care centres in Spain. PARTICIPANTS: General practitioners (GPs) registered all patients with RTIs for 15 days in winter 2008 (pre-intervention), and again in winter 2009 (post-intervention). INTERVENTIONS: Intervention activities included meetings, with the presentation and discussion of the results, and several training meetings on RTI guidelines, information brochures for patients, workshops on point-of-care tests - rapid antigen detection tests and C-reactive protein rapid test - and provision of these tests in the clinic. All GPs, with the exception of those in Catalonia, made up the full intervention group (FIG); conversely, Catalan doctors underwent the same intervention, except for the workshop on rapid tests (partial intervention group, PIG). Multilevel logistic regression was performed taking the prescription of antibiotics as the dependent variable. RESULTS: Out of a total of 309 GPs involved in the first register, 281 completed the intervention and the second register (90.9%), of which 210 were assigned to the FIG, and 71 to the PIG. The odds ratio of antibiotic prescribing after the intervention was 0.99 (95% CI: 0.89-1.10) among GPs assigned to PIG, and 0.50 (95% CI: 0.44-0.57, p<0.001) among those who were allocated to FIG. The reduction in antibiotic prescribing in FIG was more marked in flu infection, common cold, acute pharyngitis, acute tonsillitis, and acute bronchitis. CONCLUSIONS: Active participation of GPs with the performance of point-of-care tests in the clinic is accompanied by a drastic reduction of antibiotic use in RTIs, primarily in infections considered as mainly viral.

[Physicians with access to point-of-care tests significantly reduce the antibiotic prescription for common cold]. / Los médicos que disponen de pruebas rápidas disminuyen significativamente la prescripción de antibióticos en el resfriado común.

OBJECTIVE: This study was aimed at evaluating the effect of two levels of intervention on the antibiotic prescribing in patients with common cold. METHODS: Before and after audit-based study carried out in primary healthcare centres in Spain. General practitioners registered all the episodes of common cold during 15 working days in January and February in 2008 (preintervention). Two types of intervention were considered: full intervention, consisting in individual feedback based on results from the first registry, courses in rational antibiotic prescribing, guidelines, patient information leaflets, workshops on rapid tests -rapid antigen detection and C-reactive protein tests- and provision of these tests in the surgeries; and partial intervention, consisting of all the above intervention except for the workshop and they did not have access to rapid tests. The same registry was repeated in 2009 (postintervention). In addition, new physicians filled out only the registry in 2009 (control group). RESULTS: 210 physicians underwent the full intervention, 71 the partial intervention and 59 were assigned to the control group. The 340 doctors prescribed antibiotics in 274 episodes of a total of 12,373 cases registered (2.2%).The greatest percentage of antibiotic prescription was found in the control group (4.6%). The partial intervention increased the antibiotic prescription percentage from 1.1% to 2.7% while only doctors who underwent the complete intervention lead to a significant reduction of antibiotics prescribed, from 2.9% before to 0.7% after the intervention (p<0.001). CONCLUSION: Only physicians with access to rapid tests significantly reduced antibiotic prescription in patients with common cold.

C-reactive protein testing in patients with acute rhinosinusitis leads to a reduction in antibiotic use.

OBJECTIVE: To evaluate the effect of C-reactive protein (CRP) testing on the antibiotic prescribing in patients with acute rhinosinusitis. METHODS: Audit-based study carried out in primary care centres in Spain. GPs registered episodes of rhinosinusitis during 3-week period before and after an intervention. Two types of intervention were considered: full intervention group (FIG) consisting in individual feedback based on results from the first registry, courses in rational antibiotic prescribing, guidelines, patient information leaflets, workshops on rapid tests and use of the CRP test. GPs in the partial intervention group (PIG) underwent all the above intervention except for the workshop and they did not have access to CRP. Multilevel logistic regression analysis was performed considering the prescription of antibiotics as the dependent variable. RESULTS: Two hundred and ten physicians were assigned to FIG and 71 to PIG. In 2009, 59 new physicians were included as a control group. Two hundred and sixty-seven GPs visited contacts with rhinosinusitis (78.5%) registering a total of 836 cases. In the group of GPs with access to CRP rapid test, 207 patients with rhinosinusitis (75.3%) were tested and antibiotics were prescribed in 156 patients (56.7%). Antibiotics were prescribed in 87 patients (82.9%) in the group of GPs exposed to PIG and in 52 patients (86.7%) in the control group (P < 0.001). Antibiotic prescription was significantly reduced after the intervention among physicians assigned to FIG, with an odds ratio of antibiotic prescribing of 0.12 (95% confidence interval: 0.01-0.32). CONCLUSION: Physicians with access to CRP tests significantly reduced antibiotic prescription in patients with rhinosinusitis.

Effect of two interventions on reducing antibiotic prescription in pharyngitis in primary care.

OBJECTIVES: to evaluate the effect of two interventions on reducing antibiotic prescription in pharyngitis. METHODS: a prospective, non-randomized, before-after controlled study was carried out in primary care centres throughout Spain. General practitioners (GPs) registered all cases of pharyngitis during a 3 week period before and after two types of intervention in 2008 and 2009, respectively. Full intervention consisted of discussion sessions of the results of the first registry, courses for GPs, guidelines, patient information leaflets, workshops on rapid tests and the use of rapid antigen detection tests (RADTs) in their consulting offices. The physicians in the partial intervention group underwent all the above intervention except for the workshop, and RADTs were not provided. A control group was also included in 2009. Multilevel logistic regression was performed considering the prescription of antibiotics as the dependent variable. RESULTS: a total of 280 GPs registered cases with pharyngitis (70 partial intervention and 210 full intervention). Fifty-nine new physicians were included as a control group. A total of 6849 episodes of pharyngitis were registered. Antibiotic prescription was significantly lower after intervention for the full intervention group, but not for the partial intervention group. According to the multivariate model, in comparison with the control group, the odds ratio of antibiotic prescription after the intervention was 0.52 [95% confidence interval (95% CI) 0.23-1.18] in the partial intervention group and 0.23 (95% CI 0.11-0.47) in the full intervention group. CONCLUSIONS: intervention was beneficial for reducing the prescription of antibiotics, but was only statistically significant when the GPs were provided with RADTs.

ObjetivoEl estudio Happy Audit es un proyecto financiado por la Comunidad Europea, y tiene por objetivo mejorar la prescripción antibiótica en las infecciones del tracto respiratorio (ITR). Se realizó el presente estudio para conocer el tratamiento antibiótico administrado en las ITR en España y conocer qué criterios se asocian a su prescripción.DiseñoEstudio transversal realizado en enero y febrero de 2008.EmplazamientoCentros de atención primaria.ParticipantesMédicos de atención primaria de España que registraron durante 3 semanas todas las ITR mediante una plantilla.Mediciones principalesEdad y sexo, días con síntomas, signos presentes (fiebre, tos, otorrea purulenta, odinofagia, exudado amigdalar, adenopatías cervicales, disnea, aumento de esputo, esputo purulento), diagnóstico, tratamiento antibiótico y demanda de antibiótico. Se efectuó regresión logística y se consideró como variable dependiente la prescripción antibiótica.ResultadosDe los 332 médicos a los que se invitó a participar, 309 (93,1%) rellenaron los registros. Se registraron 16.751 ITR; las más frecuentes fueron el resfriado (39,7%), la faringitis (14,4%) y la bronquitis aguda (12,6%). Se prescribieron antibióticos en 4.675 ITR (27,9%), principalmente en neumonía (89,9%), amigdalitis (88,9%) y otitis media (87,3%). El criterio que más se asoció a prescripción antibiótica fue la presencia de exudado amigdalar (odds ratio [OR] de 32,1; intervalo de confianza [IC] del 95%: 24,5 a 42), seguido de otorrea (OR de 25,2; IC del 95%: 18,2 a 35) y esputo purulento (OR de 18,1; IC del 95%: 15,5 a 21,2); en cambio, fue protectora la tos (OR de 0,4; IC del 95%: 0,3 a 0,5).DiscusiónLa prescripción antibiótica en las ITR es muy elevada en España.
