Impact of a multifaceted intervention to improve antibiotic prescribing: a pragmatic cluster-randomised controlled trial.

OBJECTIVES: This study sought to assess the effectiveness and return on investment (ROI) of a multifaceted intervention aimed at improving antibiotic prescribing for acute respiratory infections in primary care. DESIGN: Large-sized, two-arm, open-label, pragmatic, cluster-randomised controlled trial. SETTING: All primary care physicians working for the Spanish National Health Service (NHS) in Galicia (region in north-west Spain). PARTICIPANTS: The seven spatial clusters were distributed by unequal randomisation (3:4) of the intervention and control groups. A total of 1217 physicians (1.30 million patients) were recruited from intervention clusters and 1393 physicians (1.46 million patients) from control clusters. INTERVENTIONS: One-hour educational outreach visits tailored to training needs identified in a previous study; an online course integrated in practice accreditation; and a clinical decision support system. MAIN OUTCOME MEASURES: Changes in the ESAC (European Surveillance of Antimicrobial Consumption) quality indicators for outpatient antibiotic use. We used generalised linear mixed and conducted a ROI analysis to ascertain the overall cost savings. RESULTS: Median follow-up was 19 months. The adjusted effect on overall antibiotic prescribing attributable to the intervention was - 4.2% (95% CI: - 5.3% to - 3.2%), with this being more pronounced for penicillins - 6.5 (95% CI: - 7.9% to - 5.2%) and for the ratio of consumption of broad- to narrow-spectrum penicillins, cephalosporins, and macrolides - 9.0% (95% CI: - 14.0 to - 4.1%). The cost of the intervention was €87 per physician. Direct savings per physician attributable to the reduction in antibiotic prescriptions was €311 for the NHS and €573 for patient contributions, with an ROI of €2.57 and €5.59 respectively. CONCLUSIONS: Interventions designed on the basis of gaps in physicians' knowledge of and attitudes to misprescription can improve antibiotic prescribing and yield important direct cost savings.

Knowledge, attitudes, perceptions and habits towards antibiotics dispensed without medical prescription: a qualitative study of Spanish pharmacists.

OBJECTIVE: To investigate community pharmacists' knowledge, attitudes, perceptions and habits with regard to antibiotic dispensing without medical prescription in Spain. METHODS: A qualitative research using focus group method (FG) in Galicia (north-west Spain). FG sessions were conducted in the presence of a moderator. A topic script was developed to lead the discussions, which were audiorecorded to facilitate data interpretation and transcription. Proceedings were transcribed by an independent researcher and interpreted by two researchers working independently. We used the Grounded Theory approach. SETTING: Community pharmacies in Galicia, region Norwest of Spain. PARTICIPANTS: Thirty pharmacists agreed to participate in the study, and a total of five FG sessions were conducted with 2-11 pharmacists. We sought to ensure a high degree of heterogeneity in the composition of the groups to improve our study's external validity. Pharmacists' participation had no gender or age restrictions, and an effort was made to form FGs with pharmacists who were both owners and non-owners, provided in all cases that they were Official Colleges of Pharmacists-registered community pharmacists. For the purpose of conducting FG discussions, the basic methodological principle of allowing groups to attain their 'own structural identity' was applied. MAIN OUTCOME MEASUREMENTS: Community pharmacists' habits and knowledge with regard to antibiotics and identification of the attitudes and/or factors that influence antibiotic dispensing without medical prescription. RESULTS: Pharmacists attributed the problem of antibiotics dispensed without medical prescription and its relationship to antibiotic resistance to the following attitudes: external responsibility (doctors, dentists and the National Health Service (NHS)); acquiescence; indifference and lack of continuing education. CONCLUSIONS: Despite being a problem, antibiotic dispensing without a medical prescription is still a common practice in community pharmacies in Galicia, Spain. This practice is attributed to acquiescence, indifference and lack of continuing education. The problem of resistance was ascribed to external responsibility, including that of patients, physicians, dentists and the NHS.

Development and validation of the knowledge and attitudes regarding antibiotics and resistance (KAAR-11) questionnaire for primary care physicians.

OBJECTIVES: The aim of this study was to develop a novel, self-administered questionnaire to identify primary-care physicians' knowledge and attitudes regarding antibiotics and resistance (KAAR). METHODS: The study population comprised primary care physicians. The study was conducted in five phases. Phase I consisted of a systematic review and qualitative focus-group study (n = 33 physicians), in which items were formulated so as to be measured on a continuous, visual analogue scale (VAS); in Phase II, content validation and face validity were evaluated by a panel of experts, which reformulated, added and deleted items; Phase III consisted of a pilot study on a population possessing similar characteristics (n = 15); in Phase IV, we analysed reliability by means of a test-retest study (n = 91) and calculated the intraclass correlation coefficients (ICCs); and in Phase V, we assessed construct validity by applying the known-groups technique, measuring the differences between contrasting groups of physicians formed according to antibiotic prescription quality indicators (group 1, n = 156 versus group 2, n = 191). RESULTS: Following Phases I and II, the questionnaire contained 16 knowledge and attitude items. Participants in the pilot study (Phase III) reported no difficulty. The test-retest study (Phase IV) showed that 11 of the 16 initial knowledge and attitude items yielded an ICC > 0.5, while analysis of known-groups validity (Phase V) showed that 13 of the 16 initial items which assessed knowledge and attitudes discriminated between physicians with good and bad indicators of antibiotics prescription. CONCLUSION: The final 11 item KAAR questionnaire appears to be valid, reliable and responsive.

Effect of Physicians' Attitudes and Knowledge on the Quality of Antibiotic Prescription: A Cohort Study.

Resistance increases with the use and abuse of antibiotics. Since physicians are primarily responsible for the decision to use antibiotics, ascertaining the attitudes and knowledge that underlie their prescribing habits is thus a prerequisite for improving prescription. Three-year follow-up cohort study (2008-2010) targeting primary-care physicians (n = 2100) in Galicia, a region in NW Spain. We used data obtained from a postal survey to assess knowledge and attitudes. A physician was deemed to have demonstrated Appropriate Quality Prescription of Antibiotics (dependent variable) in any case where half or more of the indicators proposed by the European Surveillance of Antimicrobial Consumption had values that were better than the reference values for Spain. The mail-questionnaire response rate was 68·0% (1428/2100). The adjusted increase in the interquartile OR of displaying good prescribing of antibiotics for each attitude was: 205% for fear ("When in doubt, it is better to ensure that a patient is cured of an infection by using a broad-spectrum antibiotic"; 95%CI: 125% to 321%); 119% for better knowledge ("Amoxicillin is useful for resolving most respiratory infections in primary care"; 95%CI: 67% to 193%); and 21% for complacency with patients' demands ("Antibiotics are often prescribed due to patients' demands"; 95%CI: 0% to 45%). Due to the fact that physicians' knowledge and attitudes are potentially modifiable, the implementation of purpose-designed educational interventions based on the attitudes identified may well serve to improve antibiotic prescription.

Determinants of antibiotic dispensing without a medical prescription: a cross-sectional study in the north of Spain.

OBJECTIVES: Antibiotic resistance is a major public health concern and is greatly exacerbated by inappropriate antibiotic use at a community level. The aim of this study was to ascertain which attitudes of community pharmacists were related to inappropriate antibiotic dispensing. METHODS: We conducted a cross-sectional study of community pharmacists in a region situated in northern Spain (n = 393). Personal interviews were conducted using a self-administered questionnaire. The degree of agreement with each item of knowledge and attitude was measured using an unnumbered, horizontal visual analogue scale, with replies being scored from 0 (total disagreement) to 10 (total agreement). The data were analysed using logistic regression. RESULTS: Of the total of 286 pharmacists (72.8%) who completed the questionnaire, 185 (64.7%) acknowledged having undertaken dispensing of antibiotics without a medical prescription (DAwMP). Attitudes such as patient complacency, external responsibility, indifference and insufficient knowledge were shown to be related to DAwMP. In contrast, no association was found with any of the pharmacists' personal or professional traits. CONCLUSIONS: This study confirms that, albeit unlawful, DAwMP is a common practice in Spanish pharmacies. DAwMP was seen to be usually associated with some of the attitudes evaluated.

Portuguese community pharmacists' attitudes to and knowledge of antibiotic misuse: questionnaire development and reliability.

OBJECTIVE: To develop and evaluate the reliability of a self-administered questionnaire designed to assess the attitudes and knowledge of community pharmacists in Portugal about microbial resistance and the antibiotic dispensing process. METHODS: This study was divided into the following three stages: (1) design of the questionnaire, which included a literature review and a qualitative study with focus-group sessions; (2) assessment of face and content validity, using a panel of experts and a pre-test of community pharmacists; and, (3) pilot study and reliability analysis, which included a test-retest study covering fifty practising pharmacists based at community pharmacies in five districts situated in Northern Portugal. Questionnaire reproducibility was quantified using the intraclass correlation coefficient (ICC; 95% confidence interval) computed by means of one-way analysis of variance (ANOVA). Internal consistency was evaluated using Cronbach's alpha. RESULTS: The correlation coefficients were fair to good (ICC>0.4) for all statements (scale-items) regarding knowledge of and attitudes to antibiotic resistance, and ranged from fair to good to excellent for statements about situations in which pharmacists acknowledged that antibiotics were sometimes dispensed without a medical prescription (ICC>0.8). Cronbach's alpha for this section was 0.716. CONCLUSIONS: The questionnaire designed in this study is valid and reliable in terms of content validity, face validity and reproducibility.

Strategies to improve adverse drug reaction reporting: a critical and systematic review.

BACKGROUND: Underreporting is the major limitation of a voluntary adverse drug reaction (ADR) reporting system. Many studies have assessed the effectiveness of different interventions designed to reduce underreporting. OBJECTIVE: We aimed to conduct a critical review of papers that assessed the effectiveness of different strategies to increase ADR reporting, regardless of the health professionals or patients included. DATA SOURCES: Scientific papers were selected after a search of the MEDLINE-PubMed and EMBASE scientific databases up to 7 December 2010. STUDY SELECTION: We included papers in English, French or Spanish that analysed an intervention aimed at increasing the number of reported ADRs, and quantify the results of the intervention in terms of number of reports. DATA EXTRACTION: The abstracts retrieved in both computerized searches were reviewed independently by two of the authors. Initially selected papers were thoroughly read to evaluate if they met inclusion and exclusion criteria. Data in finally selected papers were independently extracted by both authors and set in pre-designed tables. A third author took the final decision in case of disagreement. For each study, we analysed study design, type of intervention, assessment period, and results of the intervention. RESULTS: Of the 4,221 papers located that fulfilled the search criteria, 43 met the selection criteria. With the exception of one study, the interventions assessed were deemed to be effective. The vast majority of papers displayed methodological and formal limitations that lowered the grade of evidence. Multiple interventions seem to have had more impact than did single interventions. There were very few cases in which interventions were designed on the basis of inappropriate attitudes and mistaken beliefs about ADRs. CONCLUSIONS: In general, there is a need for studies of better methodological quality in this topic, so that more evidence of the effectiveness of the respective strategies can be collected for the purpose of improving ADR reporting by health professionals. It is probable that multiple interventions cause greater increases in the ADR reporting rates than single.
