Christensen LD, Vestergaard CH, Keizer E, Bech BH, Bro F, Christensen MB, Huibers L. Point-of-care testing and antibiotics prescribing in out-of-hours general practice: a register-based study in Denmark. BMC PRIMARY CARE 2024; 25:31. [PMID: 38262975 PMCID: PMC10804570 DOI: 10.1186/s12875-024-02264-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/08/2022] [Accepted: 01/02/2024] [Indexed: 01/25/2024]
Abstract
BACKGROUND Point-of-care testing may reduce diagnostic uncertainty in case of suspicion of bacterial infection, thereby contributing to prudent antibiotic prescribing. We aimed to study variations in the use of point-of-care tests (C-reactive protein test, rapid streptococcal antigen detection test, and urine dipstick) among general practitioners (GPs) and the potential association between point-of-care testing and antibiotic prescribing in out-of-hours general practice. METHODS We conducted a population-based observational register-based study, based on patient contacts with out-of-hours general practice in the Central Denmark Region in 2014-2017. The tendency of GPs to use point-of-care testing was calculated, and the association between the use of point-of-care testing and antibiotic prescribing was evaluated with the use of binomial regression. RESULTS Out-of-hours general practice conducted 794,220 clinic consultations from 2014 to 2017, of which 16.1% resulted in an antibiotic prescription. The GP variation in the use of point-of-care testing was largest for C-reactive protein tests, with an observed variation (p90/p10 ratio) of 3.0; this means that the GPs in the 90th percentile used C-reactive protein tests three times as often as the GPs in the 10th percentile. The observed variation was 2.1 for rapid streptococcal antigen detection tests and 1.9 for urine dipsticks. The GPs who tended to use more point-of-care tests prescribed significantly more antibiotics than the GPs who tended to use fewer point-of-care tests. The GPs in the upper quintile of the tendency to use C-reactive protein test prescribed 22% more antibiotics than the GPs in the lowest quintile (21% for rapid streptococcal antigen detection tests and 8% for urine dipsticks). Up through the quintiles, this effect exhibited a positive linear dose-response correlation. CONCLUSION The GPs varied in use of point-of-care testing. The GPs who tended to perform more point-of-care testing prescribed more antibiotics compared with the GPs who tended to perform fewer of these tests.

Attitudes and practices of physicians toward law enforcement on dispensing antibiotics without prescription antibiotics: Findings from a cross-sectional survey. J Family Med Prim Care 2023; 12:679-685.

Abstract
Background The government of Saudi Arabia implemented a law to enforce the law and regulations prohibiting the dispensing of antibiotics without a prescription, and studies have been conducted to assess the impact of such a law in Saudi Arabia. However, the extent to which law enforcement has changed the perceptions and attitudes of health care professionals, mainly physicians, toward antibiotic resistance is unknown in Saudi Arabia. Material and Methods A cross-sectional study was conducted in Riyad, Saudi Arabia, on 378 physicians. These physicians were mainly working in primary care centers. An online questionnaire was sent to the physicians, and it consisted of 35 items and was divided into four sections: 6 items were on sociodemographic characteristics of participants; 13 items were on the knowledge of physicians about antibiotic resistance; 8 items were on the attitude the physicians toward enforcement law, and the final 8 items were on the attitude the patients toward enforcement law in an outpatient setting. Results Around 90% of the physicians acknowledged that physicians should stop prescribing antibiotics without indication. About 29.1 % of the physicians agreed, and 56.3% showed strong agreement that law enforcement is for the patient's benefit. Similarly, 33.6% agreed, and 50.8% strongly agreed that law enforcement limits the resistance of bacteria. Around 24.3% of the patients disagreed, and 23% strongly disagreed that law enforcement does not affect anything. Around one-third of the physicians (34.4%) agreed, and 23.5% strongly agreed that the new regulation of law enforcement of antibiotic prescription increases public awareness regarding the misuse of antibiotics. Conclusion It seems that law enforcement has impacted the knowledge and attitude of physicians as they agree with law enforcement and its associated benefits for patients. They also acknowledged that law enforcement could limit the resistance to bacteria. However, not all physicians agree that law enforcement has an effect on anything, and new regulation of antibiotic prescription law increases public awareness regarding the misuse of antibiotics.

Abstract
BACKGROUND We aimed to evaluate the level of theoretical knowledge of rational antibiotic use and awareness about emergence of multidrug resistance (MDR) among the senior students at a medical school and the actively-working family physicians. METHODS This cross-sectional research was carried out between 1 February and 30 April 2019 in Malatya province. Two-hundred twenty-five senior students in the Inonu University Medical School (Group 1) and 230 actively-working family physicians in Malatya primary health care services who were found to be eligible (Group 2) were included in this study. Power analysiscalculated the minimum of 240 participants with a proportion difference of 0.18 between the groups, a type I error of 0.05 and a type II error of 0.20. A questionnaire including seven sections and 28 questions was applied to the participants. RESULTS Doctors were more hesitant in pre-graduation and more self-confident in the post-graduation period for the decision to start antibiotic treatment. In addition, doctors forget their theoretical knowledge of antibiotics over time and are unable to follow current developments after graduation. The most important concern in the pre-graduation period was the choice of antibiotics from the wrong group, while in the post-graduation period it is the fear of the presence of unproven infection. CONCLUSION Physicians' antibiotic prescribing habits, attitudes and behaviors vary before and after graduation. Sustainable education for antibiotic use for physicians after graduation can contribute positively to reduce of antimicrobial resistance rates and to increase awareness about the use of rational antibiotics.

Abstract
OBJECTIVE To investigate the relationship between guidelines and the medical practitioners' perception of optimal care for patients attending with an apparently uncomplicated acute sore throat in five countries (Australia, Germany, Sweden, UK and USA). DESIGN International cross-sectional survey. SETTING Primary healthcare (PHC). PARTICIPANTS Medical practitioners working in PHC. MAIN OUTCOME MEASURES ORs for: (A) perception of throat swabs as important, (B) perception of blood tests (C reactive protein, B-ESR and B-leucocytes) as important and (C) antibiotic prescriptions if no pathogenic bacteria isolated on throat swab. RESULTS Guidelines differed significantly; those recommending throat swabs (Sweden and USA) were associated with practitioners perceiving them as important. The UK guideline was the only one actively discouraging the use of throat swabs. Hence, compared with the USA (reference), a throat swab showing no pathogenic bacteria increased the probability of antibiotic prescribing in the UK with OR 3.2 (95% CI 1.7 to 6.1) for adults, whereas it reduced the probability in Sweden for adults OR 0.35 (95% CI 0.13 to 0.96) and children 0.19 (95% CI 0.069 to 0.50). CONCLUSIONS The differences between practitioners' perceptions of best management were associated with their guidelines. It remains unclear if guidelines influenced medical practitioners' perception or if guidelines merely reflect the consensus of current practice. A larger effort should be made to reach an international consensus in high-income countries about the best management of patients attending for an uncomplicated acute sore throat.

Abstract
Background Acute otitis media (AOM) is a common and most often self-limiting infection in childhood, usually managed in general practice. Even though antibiotics are only recommended when certain diagnostic and clinical criteria are met a high antibiotic prescription rate is observed. The study’s objective was to analyse associations between patient- and general practitioner (GP) characteristics and antibiotic prescribing for children with AOM in an effort to explain the high antibiotic prescribing rates. Methods All general practices in the Northern, Southern and Central regions of Denmark were invited to record symptoms, examinations, findings and antibiotic treatment for all children ≤7 years of age diagnosed with AOM during a four-week winter period in 2017/2018. Associations were analysed by means of multivariate logistic regressions. The study design was cross-sectional. Results GPs from 60 general practices diagnosed 278 children with AOM of whom 207 (74%) were prescribed antibiotics, most often penicillin V (60%). About half of the children had tympanometry performed. Antibiotic prescribing rates varied considerably between practices (0–100%). Antibiotic prescribing was associated with fever (odds ratio (OR) 3.69 95% confidence interval (CI) 1.93–7.05), purulent ear secretion (OR 2.35 95% CI 1.01–5.50) and poor general condition (OR 3.12 95% CI 1.31–7.46), and the practice’s antibiotic prescribing rate to other patients with symptoms of an acute respiratory tract infection (OR 2.85 CI 95% 1.07–7.60) and specifically to other children with AOM (OR 4.15 CI 95% 1.82–9.47). Conclusion GPs’ antibiotic prescribing rates for children with AOM vary considerably even considering the of signs, symptoms, request for antibiotics, and use of tympanometry. Interventions to reduce overprescribing should be targeted high-prescribing practices.

Abstract
Background Antimicrobial resistance (AMR), especially carbapenem-resistant Pseudomonas aeruginosa (CRPA), causes a serious increase in morbidity, mortality and costs. Medical professionals play an important role in curbing AMR. Previous studies overlooked the impact of workload on the relationship between medical professionals and AMR. This study aimed to explore the relationship between medical professionals and the CRPA rate as well as the moderating effect of medical professionals’ workload on this relationship. Methods A provincial-level panel dataset from 2014 to 2017 was constructed. Medical professionals were measured by the numbers of physicians, registered nurses, pharmacists, and clinical microbiologists per 1000 population. Workload was measured by the number of daily physician visits. Fixed effect model and hierarchical regression analysis were performed to explore the moderating effect of workload on medical professionals and the CRPA rate. Results The numbers of physicians, registered nurses, pharmacists and clinical technicians were significantly negative associated with the CRPA rate (coef. = − 0.889, − 0.775, − 1.176, and − 0.822; P = 0.003, 0.003, 0.011, and 0.007, respectively). Workload had a significant and positive moderating effect on physicians, registered nurses, pharmacists, clinical technicians and the CRPA rate (coef. = 1.270, 1.400, 2.210, and 1.634; P = 0.004, 0.001, 0.035, and 0.003, respectively). Conclusions Increasing the number of medical professionals may help curb the CRPA rate. Measures aimed at reducing medical professionals’ workload should be implemented to further improve CRPA performance.

Abstract
BACKGROUND This study analyzes the trajectories of antibiotic consumption using different indicators of patients' socioeconomic status, category and age-group of physicians. METHODS This study uses a pooled, cross-sectional, time series analysis. The data focus on 22 European countries from 2000 to 2014 and were obtained from the European Center for Disease and Control, Organization for Economic Co-operation and Development, Eurostat and Global Economic Monitor. RESULTS There are large variations in community and hospital use of antibiotics in European countries, and the consumption of antibiotics has remained stable over the years. This applies to the community (b = 0.07, p = 0.267, 95% -0.06, 0.19, b-squared <0.01, p = 0.813, 95% = -0.01, 0.02) as well as the hospital sector (b = -0.02; p = 0.450; CI 95% = -0.06, 0.03; b-squared <0.01; p = 0.396; CI95% = > -0.01, <0.01). Some socioeconomic variables, such as level of education, income, Gini index and unemployment, are not related to the rate of antibiotic use. The age-group of physicians and general practitioners is associated with the use of antibiotics in the hospital. An increase in the proportion of young doctors (<45 years old) leads to a significant increase in antibiotics consumption, and as the percentage of generalist practitioners increases, there use of antibiotics in hospitals decreases by 0.04 DDD/1000 inhabitants. CONCLUSIONS Understanding that age-groups and categories (general/specialist practitioners) of physicians may predict antibiotic consumption is potentially useful in defining more effective health care policies to reduce the inappropriate antibiotic use while promoting rational use.

Abstract
Objectives In Denmark, general practice is responsible for 75% of antibiotic prescribing in the primary care sector. We aimed to identify practice-related factors associated with high prescribers, including prescribers of critically important antibiotics as defined by WHO, after accounting for case mix by practice. Methods We performed a nationwide register-based survey of antibiotic prescribing in Danish general practice from 2012 to 2013. The unit of analysis was the individual practice. We used multivariable regression analyses and an assessment of relative importance to identify practice-related factors driving high antibiotic prescribing rates. Results We included 98% of general practices in Denmark ( n = 1962) and identified a 10% group of high prescribers who accounted for 15% of total antibiotic prescriptions and 18% of critically important antibiotic prescriptions. Once case mix had been accounted for, the following practice-related factors were associated with being a high prescriber: lack of access to diagnostic tests in practice (C-reactive protein and urine culture); high use of diagnostic tests (urine culture and strep A throat test); a low percentage of antibiotic prescriptions issued over the phone compared with all antibiotic prescriptions; and a high number of consultations per 1000 patients. We also found that a low number of consultations per 1000 patients was associated with a reduced likelihood of being a high prescriber of antibiotics. Conclusions An apparent underuse or overuse of diagnostic tests in general practice as well as organizational factors were associated with high-prescribing practices. Furthermore, the choice of antibiotic type seemed less rational among high prescribers.

Abstract
BACKGROUND Characteristics of high and low prescribers of antibiotics in German primary care were analysed using population data. We aimed to evaluate differences in prescribing rates and factors being associated with high prescribing, and whether high prescribers made the diagnosis of perceived bacterial infections more often. METHODS Routine data were provided by the Bavarian Association of Statutory Health Insurance Physicians. Routine data are delivered by primary care practices on a quarterly basis. We analysed data from 2011 and 2012. Patients older than 15 years with respiratory tract infections consulting a primary care physician were selected (6.647 primary care practices). Patient and physician characteristics associated with high prescribing were identified using stepwise logistic regression. RESULTS Mean prescribing rate of antibiotics was 24.9%. Prescribing rate for high prescribers was 43.5% compared to 8.5% for low prescribers. High prescribers made the diagnosis of perceived bacterial infections more often (Mhigh = 64.5%, Mlow = 45.2%). In the adjusted regression model, perceived bacterial infections were strongly associated with high prescribing (OR = 13.9, 95% CI [10.2, 18.8]). Treating patients with comorbidities was associated with lower prescribing of antibiotics (OR = 0.6, 95% CI [0.4, 0.8]). High prescribers had a higher practice volume, a higher degree of prescribing dominance, and were situated more often in deprived areas and in rural settings. INTERPRETATION Compared to findings of studies in other European countries, prescribing rates were low. There was a considerable difference between prescribing rates of high and low prescribers. Diagnostic labelling was the best predictor for high prescribing. Current guidelines recommend considering antibiotic treatment for patients with co-morbidities. In our study, treating a large number of high-risk patients was not associated with high prescribing.

Abstract
BACKGROUND Elderly people, particularly those with dementia, are sensitive to adverse anticholinergic drug effects. This study examines the prevalence of anticholinergic medication, and anticholinergic load and its predictors, in community-dwelling elderly patients (aged 75 years and older) in Australia. METHODS A research nurse visited the home of each participant (n = 1,044), compiled a list of current medications, and assessed participants' cognitive status using a subsection of the revised Cambridge Examination for Mental Disorders of the Elderly (CAMCOG-R). Anticholinergic load was determined for each patient using the Anticholinergic Drug Scale (ADS). RESULTS Multivariate analysis identified several patient factors that were associated with higher anticholinergic burden, including polypharmacy (i.e. taking five or more medications) (p < 0.001), increasing age (p = 0.018), CAMCOG-R dementia (p = 0.003), depression (p = 0.003), and lower physical quality of life (p < 0.001). The dementia group (n = 86) took a significantly higher number of medications (4.6 vs. 3.9; p = 0.04), and had a significantly higher anticholinergic load (1.5 vs. 0.8; p = 0.002) than those without dementia (n = 958). Approximately 60% of the dementia group and 40% of the non-dementia group were receiving at least one anticholinergic drug. This difference was due to the higher proportion of dementia patients taking level 1 (potentially anticholinergic) (p = 0.002) and level 3 (markedly anticholinergic) (p = 0.005) drugs. CONCLUSIONS There is considerable scope for the improvement of prescribing practices in the elderly, and particularly those with dementia. Importantly, level 1 anticholinergics have been identified as major contributors to the anticholinergic load in people with dementia. Longitudinal studies are required to determine the effects of increased and decreased anticholinergic load on cognitive function and other clinical outcomes for people with dementia.

Abstract
BACKGROUND The role of infection in the aetiology of childhood leukaemia is unknown. We used prescriptions of antibiotics from Danish pharmacies as a proxy measure for the occurrence of infections. PROCEDURE We investigated the association between exposure to antibiotics, from conception to leukaemia diagnosis, and the risk of leukaemia. Incident cases of leukaemia among children in Denmark, 1995-2008, with mothers having their earliest conception date in 1995, were individually matched to population controls by age, sex and municipality. Conditional logistic regression analyses assessed antibiotic redemptions in different time periods from conception up to 6 months before the diagnoses of all leukaemia types, acute lymphoblastic leukaemia [ALL] and ALL in 2- to 5-year-old children, adjusting for several potential confounders. RESULTS A total of 120/360 (33.3%) leukaemia mothers and 1,081/3,509 (30.8%) control mothers redeemed antibiotics during pregnancy (P = 0.32). For children, the equivalent numbers were 276 (76.7%) and 2,665 (75.9%) (P = 0.76). Histograms of antibiotic redemptions showed no temporal differences between leukaemia mothers/children and controls, which was confirmed in adjusted regression analyses (OR [95% CI]: 1.02 [0.75-1.38]). Only antibiotics redeemed during the first year after birth differed from this (OR [95% CI] for ALL diagnosed in 2- to 5-year-old children: 0.46 [0.31-0.66]). CONCLUSIONS In this hypothesis generating study, the similar amount and pattern of antibiotic redemptions in children with and without leukaemia indicate that infections play a minor role in the aetiology of childhood leukaemia. However, less antibiotic redemptions during the first year of life conform to Greaves' 'delayed infection hypothesis'.

Abstract
Objective To examine how primary care physicians (PCPs) and otolaryngologists use proton pump inhibitors (PPIs), antibiotics, antihistamines, oral and inhaled steroids, and histamine 2 antagonists in the treatment of laryngeal disorders. Study Design and Setting Retrospective analysis of data from a large, national administrative US claims database. Subjects and Methods Patients with laryngeal disorders based on ICD-9-CM codes from January 1, 2004, to December 31, 2008, seen as an outpatient by a PCP, otolaryngologist, or both and continuously enrolled for 12 months were included. Pharmacy claims, age, gender, geographic location, comorbid conditions, provider type, and laryngeal diagnosis were collected. Random-effects logistic regression and multinomial logistic regression analyses were performed. Results Of approximately 55 million individuals, 135,973 had a laryngeal diagnosis, 12 months post–index date follow-up, and an outpatient encounter with a PCP, otolaryngologist, or both. Acute laryngitis was one of the most common reasons PCPs prescribed each medication class. Nonspecific dysphonia was the most common reason otolaryngologists prescribed each medication class. Patients seen by a PCP had a higher odds ratio for receiving an antibiotic and antihistamine, and patients seen by an otolaryngologist had a greater odds ratio for receiving a PPI and inhaled steroids. After adjusting for other variables in the model, the probability that a patient seen by a PCP would receive an antibiotic was .55 and a PPI .13. If seeing an otolaryngologist, it was .44 and .22, respectively. Conclusion Differences exist regarding the prescribing patterns of PCPs and otolaryngologists in treating patients with laryngeal disorders.

Abstract
BACKGROUND Antibiotic resistance is one of the principal public health problems worldwide. Currently, inappropriate use of antibiotics is regarded as the principal determinant of resistance, with most of these drugs being prescribed outside a hospital setting. This systematic review sought to identify the factors, attitudes and knowledge linked to misprescription of antibiotics. METHODS A systematic review was conducted using the MEDLINE-PubMed and EMBASE databases. The selection criteria required that papers: (1) be published in English or Spanish; (2) designate their objective as that of addressing attitudes/knowledge or other factors related with the prescribing of antibiotics; and (3) use quality and/or quantity indicators to define misprescription. The following were excluded: any paper that used qualitative methodology and any paper that included descriptive analysis only. RESULTS A total of 46 papers that met the inclusion criteria were included in the review. They were very heterogeneous and displayed major methodological limitations. Doctors' socio-demographic and personal factors did not appear to exert much influence. Complacency (fulfilling what professionals perceived as being patients'/parents' expectations) and, to a lesser extent, fear (fear of possible complications in the patient) were the attitudes associated with misprescription of antibiotics. CONCLUSIONS Before designing interventions aimed at improving the prescription and use of antibiotics, studies are needed to identify precisely which factors influence prescribing.

Abstract
OBJECTIVES To examine general practitioners' (GPs') antibiotic prescribing patterns for acute respiratory tract infections (ARTIs) as compared with national guidelines. We also wanted to explore possible predictors of antibiotic prescription patterns. METHODS Observational study based on prescription data from 440 Norwegian GPs in December 2004 through to November 2005. Outcome measures were the type and frequency of antibiotic prescriptions for various ARTI diagnoses, with patients' and GPs' characteristics as explanatory variables. RESULTS In the study period, the 440 GPs treated a total of 142 900 ARTI episodes. In 33.5% [95% confidence interval (CI): 31.9%-35.1%] of these episodes an antibiotic was issued, of which penicillin V (pcV) accounted for 41.2% (95% CI: 37.4%-44.9%). GPs with a high number of total annual encounters had higher antibiotic prescription rates for ARTIs and used more non-pcV antibiotics compared with GPs with fewer annual patient encounters. GPs in the highest quintile with respect to the total annual encounter rate had 1.6 times the odds of prescribing antibiotics compared with GPs in the lowest quintile. Correspondingly, the odds of choosing a non-pcV antibiotic were 2.8 times higher in the top quintile of GPs compared with GPs in the bottom quintile with respect to antibiotic prescription rates. CONCLUSIONS ARTIs are frequently treated with antibiotics and often with broader spectrum agents than pcV, which is the recommended first-line antibiotic in the Norwegian guidelines. GPs with a high practice activity are, in general, more liberal with respect to the prescription of antibiotics for ARTIs, and the higher the antibiotic prescription rate, the larger the share of non-pcV agents.

Are physicians with better clinical skills on licensing examinations less likely to prescribe antibiotics for viral respiratory infections in ambulatory care settings? Med Care 2011; 49:156-65.

Abstract
BACKGROUND Viral respiratory infections (VRIs) are a common reason for ambulatory visits, and 35% are treated with an antibiotic. Antibiotic use for VRIs is not recommended, and it promotes antibiotic resistance. Effective patient-physician communication is critical to address this problem. Recognizing the importance of physician communication skills, licensure examinations were reformed in the United States and Canada to evaluate these skills. OBJECTIVE To assess whether physician clinical and communication skills, as measured by the Canadian clinical skills examination (CSE), predict antibiotic prescribing for VRI in ambulatory care. RESEARCH DESIGN AND SUBJECTS A total of 442 Quebec general practitioners and pediatricians who wrote the CSE in 1993-1996 were followed from 1993 to 2007, and their 159,456 VRI visits were identified from physician claims. MEASURES The outcome was an antibiotic prescription from a study physician dispensed within 7 days of the VRI visit. Multivariate logistic regression analyses were used to estimate the association between antibiotic prescribing for VRI and CSE score, adjusting for physician, patient, and encounter characteristics. RESULTS Better clinical and communication skills were associated with a reduction in the risk of antibiotic prescribing, but only for female physicians. Every 1-standard deviation increase in CSE score was associated with a 19% reduction in the risk of antibiotic prescribing (risk ratio, 0.81; 95% confidence interval, 0.68-0.97). Better clinical skills were associated with an even greater reduction in risk among female physicians with higher workloads (risk ratio, 0.48; 95% confidence interval, 0.29-0.79). CONCLUSION Physician clinical and communication skills are important determinants of antibiotic prescribing for VRI and should be targeted by future interventions.

Abstract
OBJECTIVES To estimate consumption of five subgroups of antihypertensive drugs by primary care areas and to analyze its variation. METHODS We performed an ecological, descriptive study of antihypertensive consumption in 239 primary care areas in the autonomous region of Valencia in 2005 followed by analysis of the variability observed. The 239 primary care areas were studied by descriptive analysis of dispensation [defined daily dose (DDD) per 1,000 inhabitants/day in pensioners (DDD/1000p/day) and in the active population (DDD/1000a/day)] and standardized consumption ratios. Small-area variation analysis was used to analyze the observed variability. Associations among dispensations of the distinct therapeutic subgroups were also analyzed. RESULTS Overall antihypertensive use in the autonomous region of Valencia in 2005 was 235.6DDD/1000/day. This consumption was concentrated in pensioners (800DDD/1000p/day vs. 73DDD/1000a/day). Consumption of antihypertensive subgroups oscillated from 442DDD/1000p/day for drugs with action on the renin-angiotensin system to 32DDD/1000p/day for doxazosin. The active population showed similar patterns. Variation in consumption was moderate, with coefficients of variation from 0.20 to 0.40 (slightly greater for the active population). Associations among dispensations of the different therapeutic subgroups were strong. CONCLUSIONS This study shows major variations in the overall consumption of antihypertensive drugs among primary care areas of the autonomous region of Valencia. These results suggest that variation may be associated with problems of underutilization in areas with lower consumption.

Abstract
OBJECTIVE Inappropriate use of antibiotics is associated with increased antibiotic resistance in the community. About 90% of all antibiotic prescriptions in Norway are issued by general practitioners and in 60% issued for respiratory tract infections. The article describes and analyses antibiotic prescription patterns by general practitioners in Vestfold, Norway. DESIGN Prospective cohort study. SUBJECTS A total of 145 list-holding general practitioners in Vestfold, Norway in February to March 2003. METHODS Merging of two electronic administrative data sets: antibiotic prescriptions dispensed in pharmacies and general practitioners' electronic bills from the National Insurance Agency. MAIN OUTCOME MEASURES Proportion and type of antibiotic prescribed for different respiratory tract infectious diagnoses. RESULTS We found large variations among general practitioners' antibiotic prescription habits. In 27% of consultations with RTI diagnoses, an antibiotic was prescribed; 37% were for Penicillin V and 28% for a macrolide. Quinolones and cephalosporins were only rarely prescribed. In a logistic regression analysis the following factors were independently associated with antibiotic prescription rate: type of infection, type of contact, being a general practitioner specialist, and years since medical exam. In another logistic regression analysis the following factors were independently associated with broad-spectrum antibiotic prescription: type of infection, age of patient, type of contact, being a specialist, length of list, and being a high prescriber of antibiotics. CONCLUSION The variation in proportion of total antibiotic prescribing and broad-spectrum prescription for respiratory tract infections is high, and reveals potentials to change general practitioners' prescription behaviour, in order to maintain the positive situation in Norway as to antibiotic resistance.

Abstract
BACKGROUND Inappropriate use of antibiotics promotes antibiotic resistance. Little is known about physician characteristics that may be associated with inappropriate antibiotic prescribing. Our objective was to assess whether physician knowledge, time in practice, place of training and practice volume explain the differences in antibiotic prescribing among physicians. METHODS A historical cohort of 852 primary care physicians in Quebec who became certified between 1990 and 1993 was followed for their first 6-9 years of practice (1990-1998). We evaluated whether inappropriate antibiotic prescribing had occurred during the study period (1990-1998) for viral (prescription of antibiotics) and bacterial (prescription of second-or third-line antibiotics given orally) infections. We used logistic regression to estimate the independent contributions of time in practice, practice volume, place of medical training and scores on licensure examinations. Physician sex and visit setting were controlled for, as were patient age, sex, education, income and geographic area of residence. RESULTS A total of 104 230 patients who received a diagnosis of a viral infection and 65 304 who received a diagnosis of a bacterial infection were included in our study. International medical graduates were more likely than University of Montréal graduates to prescribe antibiotics for viral respiratory infections (risk ratio [RR] 1.78, 95% confidence interval [CI] 1.30-2.44). Inappropriate antibiotic prescribing increased with time in practice. Physicians with a high practice volume were more likely than those with low practice volume to prescribe antibiotics for viral respiratory infections (RR 1.27, 95% CI 1.09-1.48) and to prescribe second-and third-line antibiotics as first-line treatment (RR 1.20, 95% CI 1.06-1.37). Physician scores on licensure examinations were not predictive of inappropriate antibiotic prescribing. INTERPRETATION International medical graduates, physicians with high-volume practices and those who were in practice longer were more likely to prescribe antibiotics inappropriately. Developing effective interventions will require increased knowledge of the mechanisms that underlie these predictors of inappropriate antibiotic prescribing.

Abstract
PURPOSE To analyse the association between general practitioners' clinical interest and prescribing rates in four clinical areas: dyspepsia, depression, headache and diabetes. METHODS Data concerning general practitioners' prescribing during 2004 were retrieved from a pharmacy database and linked with data from a physician questionnaire and the National Health Insurance Register. To counterbalance differences in practice populations all 1-year prevalences of prescribing were standardised according to age and gender. Participants were asked 'To what extent do you find the following areas interesting from a professional point-of- view?' Four rating categories were used. The association between clinical interest and standardised prescribing rates was investigated using logistic regression, the Kruskal-Wallis test and a trend test. RESULTS A total of 68 (72%) single-handed general practitioners representative of the total group completed the questionnaire. We observed a two-fold ratio between the 90% and the 10% percentiles of the 1-year prevalences of antisecretory drugs, antidepressants, migraine drugs as well as anti-diabetics. The variation in prescribing of antidepressant and antisecretory drugs was far above chance level. No significant association with clinical interest could, however, be observed for any of the four clinical areas. CONCLUSION General practitioners' prescribing of the four classes of medical drugs varied considerably. However, only part of this variation was based on chance. This study did not confirm our hypothesis that general practitioners' level of clinical interest in one area corresponds with their prescribing of drugs used within that area.

Abstract
Background More than half of all antibiotic prescriptions in general practice are issued for respiratory tract infections (RTIs), despite convincing evidence that many of these infections are caused by viruses. Frequent misuse of antimicrobial agents is of great global health concern, as we face an emerging worldwide threat of bacterial antibiotic resistance. There is an increasing need to identify determinants and patterns of antibiotic prescribing, in order to identify where clinical practice can be improved. Methods/Design Approximately 80 peer continuing medical education (CME) groups in southern Norway will be recruited to a cluster randomized trial. Participating groups will be randomized either to an intervention- or a control group. A multifaceted intervention has been tailored, where key components are educational outreach visits to the CME-groups, work-shops, audit and feedback. Prescription Peer Academic Detailers (Rx-PADs), who are trained GPs, will conduct the educational outreach visits. During these visits, evidence-based recommendations of antibiotic prescriptions for RTIs will be presented and software will be handed out for installation in participants PCs, enabling collection of prescription data. These data will subsequently be linked to corresponding data from the Norwegian Prescription Database (NorPD). Individual feedback reports will be sent all participating GPs during and one year after the intervention. Main outcomes are baseline proportion of inappropriate antibiotic prescriptions for RTIs and change in prescription patterns compared to baseline one year after the initiation of the tailored pedagogic intervention. Discussion Improvement of prescription patterns in medical practice is a challenging task. A thorough evaluation of guidelines for antibiotic treatment in RTIs may impose important benefits, whereas inappropriate prescribing entails substantial costs, as well as undesirable consequences like development of antibiotic resistance. Our hypothesis is that an educational intervention program will be effective in improving prescription patterns by reducing the total number of antibiotic prescriptions, as well as reducing the amount of broad-spectrum antibiotics, with special emphasis on macrolides.

Abstract
OBJECTIVE To examine the strategies that general dental practitioners (GDPs) use to administer antibiotic prophylaxis and to study the agreement between the administration strategies of GDPs and local recommendations. METHODS Postal questionnaires in combination with telephone interviews were used. Two hundred GDPs in two Swedish counties, Skåne and Orebro, were asked to participate. The response rate was 51% (n = 101). The GDPs were presented with eight simulated cases of patients with different medical conditions for which antibiotic prophylaxis might be considered necessary when performing dental procedures (scaling, tooth removal, root canal treatment). The administration strategies of the GDPs were compared with local recommendations. RESULTS In general, the variation in the administration strategies of the GDPs was large. For two medical conditions, type 1 diabetes that was not well controlled and hip prosthesis, significantly more GDPs in Skåne than in Orebro administered antibiotic prophylaxis for tooth removal. Agreement between the administration strategies of the GDPs and local recommendations was low. Differences between the two counties were non-significant. Furthermore, within Orebro, GDPs who did not have formal access to local recommendations did not differ in their administration strategies from those who did. The choice of substance was seldom in agreement with the substance recommended, while the majority followed the recommended duration of treatment. CONCLUSION Although recommendations existed, their impact appeared to be limited. This is significant, since the implementation of recommendations is crucial in making clinical practice more effective and in promoting the health of patients.

Abstract
OBJECTIVE To assess the face validity of both simple and advanced quality indicators for prescribing in general practice. METHODS In a three-round Delphi study, 100 randomly selected general practitioners (GPs) in Denmark rated 18 indicators for prescribing of non-steroidal anti-inflammatory drugs. All indicators were based on prescription register data and focused on different prescribing aspects. Advanced indicators contained information at the patient level, viz. age, sex and history of drug use, while simple indicators only used drug statistics at practice level. Indicators were rated on a nine-point Likert scale. Consensus among GPs was defined as interquartile ranges of three or less. A median rating of 7-9 was interpreted as face validity and a median rating of 1-3 as no face validity. RESULTS Participation in the study was accepted by 44 GPs and 37 completed all three rounds. Three indicators based on patient level data and focusing on adverse effects were assessed to have face value. One indicator focusing on costs and based on practice level data was considered unsuitable for evaluating the quality of prescribing. Consensus was not reached for the remaining indicators. CONCLUSIONS GPs do not regard simple indicators based on aggregated data at practice level as suitable for evaluating the prescribing quality in general practice, but prefer indicators that rest on clinical data at the patient level.

Eur J Clin Pharmacol 2003; 59:143-9.

Abstract
OBJECTIVE The use of antidepressants (ADs) has escalated and prompted considerable debate. Many depressed patients go unrecognised or under-treated and the area of indication of the new ADs is widening. The aim of this study was to analyse (i). the variation in general practitioners' prescribing of ADs by comparing with prescribing of other drug groups and (ii). whether the general prescribing behaviour, practice activity and demography are associated with the AD prescribing. METHODS Analysis of AD prescribing patterns among 174 general practices (93.5%) in the County of Funen, Denmark. Age- and sex-standardised 1-year incidences and prevalences of AD prescribing for patients listed were calculated using individual prescription data from Odense University Pharmacoepidemiologic Database. Data about health services and practice demography were obtained from the Health Insurance Register. The variation in AD 1-year prevalence was compared with other drug groups by a variation index (90%/10% percentile). Univariate linear regression analysis was used to examine associations between practice characteristics and prescribing. RESULTS The 1-year prevalence of AD prescribing varied sixfold, no more than the prevalence of five other drug groups. Practices with high yearly: general prescribing prevalence, mean number of drugs per medicated patient, number of surgery consultations/100 patients and counsellings/100 surgery consultations showed the highest yearly prevalence of AD prescribing. Single-handed practices had higher AD prescribing rates than partnerships. The relative use of selective serotonin re-uptake inhibitors and other new ADs showed only little variation (10% and 90% percentiles as close as 66-86%), but practices with high 1-year prevalence and incidence most often chose the new ADs. CONCLUSION Analysis of inter-practice variation showed no extraordinary quality problems with regard to AD prescribing, but does not exclude that there might be problems. The general prescribing pattern of the general practitioners seems essential to their attitude to AD prescribing. The relationship between counselling and prescribing was a feature specific to ADs and deserves further investigation. Quality indicators are needed to understand differences in AD prescribing, and studies based on prescription data have to be supplemented with individual clinical data.

Abstract
Limited information is available about systemic antibiotic use among children in Germany. We therefore assessed prescription patterns by office-based physicians to analyse antibiotic consumption in early childhood. A total of 331 children < 6 years were eligible for inclusion. The number of antibiotic prescriptions, consumed daily doses, number of treatment courses, types of antibiotics and diagnoses for prescribing were determined. The prevalence of systemic antibiotic treatment was 42.9%. Antibiotic consumption was highest between 2 and 3 years of age (55.8%). The percentage of children receiving one, two or three courses of antibiotic treatment was 49.3, 28.2 and 16.2%, respectively. Acute otitis media (32.2%), upper respiratory tract infections (18.9%), tonsillitis (15.9%) and acute bronchitis (15.4%) were principal indications for treatment. Macrolides were most frequently prescribed (48.1%), followed by penicillin V (21.3%), broad-spectrum penicillins (14.3%), sulfonamides (10.5%) and cephalosporins (5.8%). Antibiotics not recommended for particular indication were selected in 5-43% of cases. The considerable prescription of systemic antibiotics to children in many European countries is also the case in Germany. A noteworthy trend emerged for suboptimal prescribing with second-line antibiotics. As such treatment may be associated with the development of bacterial resistance, improved guidelines for antibiotic treatment should be drawn up and enforced.

Abstract
As the ultimate consumers, patients play an important role in the emergence, spread and control of bacterial resistance to antibiotics. Improved knowledge of antibiotics and the problem of resistance, as well as a better understanding of beliefs, pressures/concerns, and expectations, from both the patient's and physician's perspectives, are fundamental for controlling antibiotic use. There is growing evidence to suggest that empowering patients through implementation of patient-centered health-care strategies, such as shared decision-making, in conjunction with educational initiatives help to change attitudes and behavior, and improve access to and completion of appropriate antimicrobial therapy. This, in turn, may help to control the development and spread of resistance to antibiotics.

Abstract
The reported association between antibiotic prescribing and resistance may be subject to bias or confounding. Bias describes any effect at any stage of investigation or inference tending to produce results that depart systematically from the true value. A confounding variable is one that is associated independently with both exposure and outcome. Confounding variables may create an apparent association or mask a real association. Pharmacoepidemiology is the study of the use and the effects of drugs in large numbers of people. We have used standard pharmacoepidemiological methods to investigate sources of bias and confounding in the association between prescribing and resistance. We conclude that the association is statistically valid and that the consistency of evidence supports a cause-effect relationship. Nonetheless, several important sources of bias and confounding must be taken into account in future studies that analyze the impact of prescribing policies on resistance.

Abstract
The prescribing habits of a randomly selected approximately 10 per cent sample of South Australian general dental practitioners were obtained by postal questionnaire. Sixty-eight (61 per cent) usable replies were received and analysed. Generally, there was an appropriate level of knowledge of antibiotic prescription. However, there was a tendency toward over-prescription and a demonstrated lack of knowledge of the incidence of adverse reactions, development of multiresistant strains and prophylaxis against bacterial endocarditis. All of these areas are real challenges to the profession, whether in an overall global community health sense or in a highly individualized clinical or medico-legal sense. These issues are discussed and the profession is urged to reconsider and re-educate itself on these challenges.
