New paradigms on antibiotic recommendations for community-acquired infections in Spain.

Over the last years, the susceptibility activity of the most common microorganisms causing community-acquired infections has significantly changed in Spain. Based on the susceptibility rates of Streptococcus pyogenes, Streptococcus pneumoniae, Haemophilus influenzae, Escherichia coli, and Klebsiella pneumoniae collected from outpatients aged 15 or older with symptoms of respiratory or urinary tract infections in several Microbiology Departments in Catalonia in 2021, penicillin V should be first choice for most respiratory tract infections, amoxicillin and clavulanate for chronic obstructive pulmonary disease exacerbations and a single dose of fosfomycin or a short-course nitrofurantoin should remain first-line treatments for uncomplicated urinary tract infections. Updated information on antimicrobial resistance for general practitioners is crucial for achieving appropriate empirical management of the most common infections by promoting more rational antibiotic use.

Clinical prediction of laboratory-confirmed influenza in adults with influenza-like illness in primary care. A randomized controlled trial secondary analysis in 15 European countries.

BACKGROUND: Clinical findings do not accurately predict laboratory diagnosis of influenza. Early identification of influenza is considered useful for proper management decisions in primary care. OBJECTIVE: We evaluated the diagnostic value of the presence and the severity of symptoms for the diagnosis of laboratory-confirmed influenza infection among adults presenting with influenza-like illness (ILI) in primary care. METHODS: Secondary analysis of patients with ILI who participated in a clinical trial from 2015 to 2018 in 15 European countries. Patients rated signs and symptoms as absent, minor, moderate, or major problem. A nasopharyngeal swab was taken for microbiological identification of influenza and other microorganisms. Models were generated considering (i) the presence of individual symptoms and (ii) the severity rating of symptoms. RESULTS: A total of 2,639 patients aged 18 or older were included in the analysis. The mean age was 41.8 ± 14.7 years, and 1,099 were men (42.1%). Influenza was microbiologically confirmed in 1,337 patients (51.1%). The area under the curve (AUC) of the model for the presence of any of seven symptoms for detecting influenza was 0.66 (95% confidence interval [CI]: 0.65-0.68), whereas the AUC of the symptom severity model, which included eight variables-cough, fever, muscle aches, sweating and/or chills, moderate to severe overall disease, age, abdominal pain, and sore throat-was 0.70 (95% CI: 0.69-0.72). CONCLUSION: Clinical prediction of microbiologically confirmed influenza in adults with ILI is slightly more accurate when based on patient reported symptom severity than when based on the presence or absence of symptoms.

Influenza is usually diagnosed clinically. However, the accuracy of a diagnosis of influenza based on clinical features is limited because symptoms overlap considerably with those caused by other microorganisms. This study examined whether identification of the severity rather than the presence of key signs and symptoms could aid in the diagnosis of influenza, thereby helping clinicians to determine when antiviral agent use is appropriate. The authors used the database of a previous randomized clinical trial on the effectiveness of an antiviral carried out in primary care centers in 15 countries in Europe during three epidemic periods from 2015/2016 to 2017/2018. Participants with influenza symptoms were included and they were asked about the presence and severity of different symptoms during the baseline visit with their doctors and a nasopharyngeal swab was taken for microbiological analysis. Overall, only 51% of the patients aged 18 or older had a confirmed influenza infection. Clinical findings are not particularly useful for confirming or excluding the diagnosis of influenza. However, the results of our study recommend considering how intense the different symptoms are, since key symptoms rated as moderate or severe are slightly better for predicting flu rather than the presence or absence of these symptoms.

Sociodemographic characterisation of antibiotic heavy users in the Danish elderly population.

AIMS: The development of effective interventions to reduce inappropriate use of antibiotics in the elderly population requires knowledge on who can benefit from such interventions. Thus, we aimed to identify and characterise antibiotic heavy users among elderly patients in general practice with respect to sociodemographic variables. METHODS: We conducted a retrospective nationwide register-based study on all Danish elderly citizens (⩾65 years) who redeemed an antibiotic prescription in 2017. Heavy users were defined as the 10% with the highest excess use, that is, their recorded use minus the average use for their sex, age group and comorbidity level as estimated from a linear regression model. Comparative analyses of sociodemographic characteristics (civil status, employment status, urbanity, educational level and country of origin) of heavy users and non-heavy users were performed using logistic regression models. RESULTS: The study population consisted of 251,733 elderly individuals, who in total redeemed 573,265 prescriptions of antibiotics. Heavy users accounted for 68% of all excess use of antibiotics. In multivariable analyses, individuals with an educational level above basic schooling, non-retired, residing in an urban municipality and being born in a country outside Scandinavia all had lower odds of being a heavy user. Widowed, divorced or single individuals had higher odds of being a heavy user compared with married individuals. Relative importance analyses showed that civil status and educational level contributed considerably to the explained variance. CONCLUSIONS: This study found an association between sociodemographic characteristics and risk of being a heavy user, indicating that sociodemographic variation exists with regard to antibiotic prescribing.

Use and quality of point-of-care microscopy, urine culture and susceptibility testing for urinalysis in general practice.

Objective: To describe the use and quality of point-of-care (POC) microscopy, urine culture and susceptibility testing performed in general practice in Northern Denmark from 2013 to 2018.Design: Descriptive studySetting: General practices receiving a fee for examining urine samples.Subjects: Simulated urine samples containing uropathogenic bacteria distributed by the organisation for improvement of microbiological quality (MIKAP).Main outcome measures: Percentage of use and correct answers for microscopy, culture and susceptibility testing.Results: A total of 5361 samples were analysed by the use of microscopy (39.7%), culture (66.0%) and/or susceptibility testing (76.5%). For culture, Flexicult SSI urinary kittm (87.6%) demonstrated the highest percentage of correct answers followed by chromogenic agar (85.1%) and 2-plate dipslide (85.2%). Mueller Hinton agar with tablets had the highest percentage of correct answers for susceptibility testing of most bacterial strains (84.6%), followed by Flexicult (77.2%). Furthermore, susceptibility testing with tablets (range: 76.1-84.6%) was found to be more accurate than discs (range: 72.9-75.5%). Overall, the highest percentage of correct answers was obtained when examining urine samples containing Escherichia coli: Microscopy (78.3%), culture (87.0%) and susceptibility testing (range: 84.3-90.7%).Conclusion: The quality of POC testing in general practice was high when examining urine samples containing the most common uropathogen E. coli. Surprisingly, susceptibility testing was more frequently used than culture. This approach may compromise the treatment decision as only cultures contribute with information about the flora composition and bacterial quantification. Interestingly, microscopy was the least used method even though the result may be reached within a few minutes.Key pointsThe quality of POC tests (microscopy, urine culture, susceptibility testing) performed in general practice was high when examining urine containing E. coli, whereas difficulties were observed for samples including S. saprophyticus or K. pneumoniae.Susceptibility testing was more often performed than urine culture, which indicates a problem as only urine cultures contribute with information about the flora composition and bacterial quantification.

Oseltamivir plus usual care versus usual care for influenza-like illness in primary care: an open-label, pragmatic, randomised controlled trial.

BACKGROUND: Antivirals are infrequently prescribed in European primary care for influenza-like illness, mostly because of perceived ineffectiveness in real world primary care and because individuals who will especially benefit have not been identified in independent trials. We aimed to determine whether adding antiviral treatment to usual primary care for patients with influenza-like illness reduces time to recovery overall and in key subgroups. METHODS: We did an open-label, pragmatic, adaptive, randomised controlled trial of adding oseltamivir to usual care in patients aged 1 year and older presenting with influenza-like illness in primary care. The primary endpoint was time to recovery, defined as return to usual activities, with fever, headache, and muscle ache minor or absent. The trial was designed and powered to assess oseltamivir benefit overall and in 36 prespecified subgroups defined by age, comorbidity, previous symptom duration, and symptom severity, using a Bayesian piece-wise exponential primary analysis model. The trial is registered with the ISRCTN Registry, number ISRCTN 27908921. FINDINGS: Between Jan 15, 2016, and April 12, 2018, we recruited 3266 participants in 15 European countries during three seasonal influenza seasons, allocated 1629 to usual care plus oseltamivir and 1637 to usual care, and ascertained the primary outcome in 1533 (94%) and 1526 (93%). 1590 (52%) of 3059 participants had PCR-confirmed influenza infection. Time to recovery was shorter in participants randomly assigned to oseltamivir (hazard ratio 1·29, 95% Bayesian credible interval [BCrI] 1·20-1·39) overall and in 30 of the 36 prespecified subgroups, with estimated hazard ratios ranging from 1·13 to 1·72. The estimated absolute mean benefit from oseltamivir was 1·02 days (95% [BCrI] 0·74-1·31) overall, and in the prespecified subgroups, ranged from 0·70 (95% BCrI 0·30-1·20) in patients younger than 12 years, with less severe symptoms, no comorbidities, and shorter previous illness duration to 3·20 (95% BCrI 1·00-5·50) in patients aged 65 years or older who had more severe illness, comorbidities, and longer previous illness duration. Regarding harms, an increased burden of vomiting or nausea was observed in the oseltamivir group. INTERPRETATION: Primary care patients with influenza-like illness treated with oseltamivir recovered one day sooner on average than those managed by usual care alone. Older, sicker patients with comorbidities and longer previous symptom duration recovered 2-3 days sooner. FUNDING: European Commission's Seventh Framework Programme.

Antibiotic prescribing in Danish general practice in the elderly population from 2010 to 2017.

OBJECTIVE: This study aimed to describe prescription of antibiotics to the elderly population in general practice in Denmark from 2010-2017. DESIGN: This is a national register-based observational study. SETTING: General practice, Denmark. MAIN OUTCOME MEASURE: The main outcome measure was prescriptions/1,000 inhabitants/day (PrID) in relation to year, age and sex, indication, and antibiotic agent. SUBJECTS: In this study, we included inhabitants of Denmark, ≥65 years of age between 01st July 2010-30th June 2017. RESULTS: A total of 5,168,878 prescriptions were included in the study. Antibiotic prescriptions decreased from 2.2 PrID to 1.7 (-26.9%, CI95% [-31.1;-22.4]) PrID during the study. The decrease in PrID was most noticeable among 65-74-year-olds (-25%). The ≥85-year-olds were exposed to twice as many PrID than the 65-74-year-olds, but only accounted for 20% of the total use. Urinary tract infection (UTI) was the most common indication for antibiotic prescription and increased with advancing age. The most commonly prescribed antibiotics were pivmecillinam and phenoxymethylpenicillin. Prescribing with no informative indication was present in one third of all cases. CONCLUSION: The prescription of antibiotics in the elderly population in general practice decreased from 2010 to 2017. The oldest age group was exposed twice as frequently to antibiotic prescriptions as the 65-74-year-olds. The smallest reduction was observed for the ≥85-year-olds, suggesting targeting interventions at this group.Key PointsHigh antibiotic use among elderly is well known and studies indicate mis- and overuse within this population. Our study shows.The prescription rate is decreasing within all age groups of the elderly population.The ≥85-year-olds receive twice as many prescriptions/1000/day as the 65-74-years-olds.

Association Between Danish Physicians' Religiosity and Spirituality and Their Attitudes Toward End-of-Life Procedures.

Several studies in different countries have investigated the influence of physician characteristics (such as ethnicity, gender and personal values) on attitudes in end-of-life (EOL) decision-making. While patients and relatives formally decide about issues related to EOL, the physician often ends up with a pivotal role in the decision-making process. Consequently, the influence of the personal beliefs and values of physicians on decisions in EOL care is central in the clinical encounter. The aim of this study was to investigate whether the religious and spiritual characteristics of Danish physicians are associated with their attitudes toward certain EOL decisions, particularly concerning euthanasia (E), physician-assisted suicide (PAS), sedation into unconsciousness in dying patients (SUDP), and withdrawal of life support. The study is based on a questionnaire that was mailed to 1485 physicians in the Region of Southern Denmark. We found that being more religious meant being more likely to object to E/PAS, with gender also being a significant factor, in that females were more likely to object to E/PAS than males. Being more religious also meant being more likely to object to SUDP. In a medical practice, revolving around patient-centered care, and often linked with ideals of value neutrality, it is important to gain an understanding of the influences of personal values of physicians on attitudes toward several areas of clinical decision-making. This study contributes to the knowledge of, and possible reflections upon, the impact of physicians' personal beliefs and values on their attitudes toward important decisions in their patients' lives.

Reducing antibiotic prescribing for lower respiratory tract infections 6 years after a multifaceted intervention.

AIMS: Few studies have evaluated the long-term impact of interventions on antibiotic prescription for lower respiratory tract infections (LRTI). This study was aimed at evaluating the use of antibiotics prescribed for LRTIs by general practitioners (GP) who underwent a multifaceted intervention carried out 6 years earlier. METHODS: General practitioners who had completed two registrations in 2008 and 2009 were again invited to participate in a third audit-based study in 2015. A multifaceted intervention was held 1-3 months before the second registration. A new group of GPs with no previous training on the rational use of antibiotics were also invited to participate and acted as controls. Multilevel logistic regression was performed considering the prescription of antibiotics as the dependent variable. RESULTS: A total of 121 GPs of the 210 who underwent the intervention (57.6%) and 117 control GPs registered 4333 episodes of LRTIs. On adjustment for covariables, compared with the antibiotic prescription for LRTIs observed just after the intervention, antibiotic prescription slightly increased 6 years later among GPs who had undergone the intervention (OR 1.17, 95% CI 0.95-1.43), while control GPs prescribed significantly more antibiotics (OR 2.31, 95% CI 1.62-3.29). However, withholding antibiotic prescribing with C-reactive protein (CRP) values <10 mg/L was more frequently observed just after the intervention compared 6 years later (12.7% vs 32.2%; P < 0.01). CONCLUSIONS: Antibiotic prescribing for LRTIs remains low 6 years after an intervention, although GPs are less confident to withhold antibiotic therapy in patients with low CRP levels.

Characteristics of Religious and Spiritual Beliefs of Danish Physicians: And Likelihood of Addressing Religious and Spiritual Issues with Patients.

This study investigated the association between physicians' R/S characteristics and frequency of addressing patients' R/S issues. Information was obtained through a questionnaire mailed to 1485 Danish physicians (response rate 63%) (42% female). We found significant associations between physicians' personal R/S and the frequency of addressing R/S issues. Moreover, we identified significant gender differences in most R/S characteristics. However, no differences in frequency of addressing R/S issues were identified across gender. This raises some questions regarding the effects of gender on associations between R/S characteristics and frequency of addressing R/S issues.

Ibuprofen versus pivmecillinam for uncomplicated urinary tract infection in women-A double-blind, randomized non-inferiority trial.

BACKGROUND: Although uncomplicated urinary tract infections (UTIs) are often self-limiting, most patients will be prescribed antibiotic treatment. We assessed whether treatment with ibuprofen was non-inferior to pivmecillinam in achieving symptomatic resolution by day 4, with a non-inferiority margin of 10%. METHODS AND FINDINGS: This was a randomized, controlled, double-blind non-inferiority trial. We recruited patients from 16 sites in a general practice setting in Norway, Sweden, and Denmark. Non-pregnant women aged 18-60 years presenting with symptoms of uncomplicated UTI were screened for eligibility from 11 April 2013 to 22 April 2016. Patients with informed consent were randomized (1:1 ratio) to treatment with either 600 mg ibuprofen or 200 mg pivmecillinam 3 times a day for 3 days. The patient, treating physician, and study personnel were blinded to treatment allocation. The primary outcome was the proportion of patients who felt cured by day 4, as assessed from a patient diary. Secondary outcomes included the proportion of patients in need of secondary treatment with antibiotics and cases of pyelonephritis. A total of 383 women were randomly assigned to treatment with either ibuprofen (n = 194, 181 analyzed) or pivmecillinam (n = 189, 178 analyzed). By day 4, 38.7% of the patients in the ibuprofen group felt cured versus 73.6% in the pivmecillinam group. The adjusted risk difference with 90% confidence interval was 35% (27% to 43%) in favor of pivmecillinam, which crossed the prespecified non-inferiority margin. Secondary endpoints were generally in favor of pivmecillinam. After 4 weeks' follow-up, 53% of patients in the ibuprofen group recovered without antibiotic treatment. Seven cases of pyelonephritis occurred, all in the ibuprofen group, giving a number needed to harm of 26 (95% CI 13 to 103). Five of these patients were hospitalized and classified as having serious adverse events; 2 recovered as outpatients. A limitation of the study was the extensive list of exclusion criteria, eliminating almost half of the patients screened. We did not register symptoms in the screening process; hence, we do not know the symptom burden for those who declined to participate. This might make our results less generalizable. CONCLUSIONS: Ibuprofen was inferior to pivmecillinam for treating uncomplicated UTIs. More than half of the women in the ibuprofen group recovered without antibiotics. However, pyelonephritis occurred in 7 out of 181 women using ibuprofen. Until we can identify those women who will develop complications, we cannot recommend ibuprofen alone as initial treatment to women with uncomplicated UTIs.

Comparison of antibiotic prescribing and antimicrobial resistance in urinary tract infections at the municipal level among women in two Nordic regions.

Objectives: To describe and compare the prescribing of antibiotics used for urinary tract infections and its correlation with resistance in Escherichia coli in urinary samples across two adjacent regions-the Capital Region and the Skaane Region-and their municipalities in Denmark and Sweden. Methods: The Capital Region consists of 29 municipalities and 725 960 female inhabitants aged ≥18 years and the Skaane Region consists of 33 municipalities and 515 668 female inhabitants aged ≥18 years. Aggregated data from outpatient care on the prescribing of pivmecillinam, trimethoprim and nitrofurantoin from both regions were analysed. The Department of Clinical Microbiology in both regions provided data on E. coli resistance in urinary samples from women aged ≥18 years. Data were measured as the number of prescriptions/1000 women/year, number of DDDs/1000 women/year and DDDs/prescription. Correlation analyses between antibiotic prescribing and antibiotic resistance rates were performed. Results: Antibiotic prescribing and resistance rates were significantly higher in the Capital Region compared with the Skaane Region. Large variations in prescription and resistance rates were found at the municipal level, but there were no correlations between the antibiotic prescription and resistance rates when each region was analysed separately. Conclusions: Although closely related, there are large differences in antibiotic prescribing and antibiotic resistance. It is suggested that the regional guidelines are an important driver and explanatory factor for the variations; however, further research is needed in this new field and factors such as the influence of cultural aspects should be the target of further research.

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.

Use of diagnostic tests and the appropriateness of the treatment decision in patients with suspected urinary tract infection in primary care in Denmark - observational study.

BACKGROUND: Inappropriate prescription of antibiotics is the leading driver of antimicrobial resistance (AMR). The majority of antibiotics are prescribed in primary care. Understanding how general practitioners (GPs) use diagnostic tests and the effect on treatment decision under daily practice conditions is important to reduce inappropriate prescription of antibiotics. The aim of the study was to investigate the use of diagnostic tests in primary care patients with suspected urinary tract infection (UTI) and to assess the appropriateness of the treatment decision (TD) under daily practice conditions in Denmark. METHODS: Prospective observational study. Symptomatic adult patients consulting general practice with suspected UTI recruited over 12 months. The diagnostic workup was registered in a standardized form. The appropriateness of the TD was assessed based on the results of a culture performed at a reference microbiological laboratory. TD was considered appropriate if a patient had a positive culture and was prescribed antibiotics or had a negative culture and was not prescribed antibiotics. TD was considered inappropriate if a patient had a negative culture and was prescribed antibiotics (overtreatment) or had a positive culture and was not prescribed antibiotics (undertreatment). RESULTS: Four hundred and eighty-eight patients were included. Dipstick was used in 98% of the patients and urine culture was used in 89% of the patients; 317 had the culture performed in practice and 117 had the culture performed at the hospital. The appropriateness of the final TD was significantly (p = 0.04) lower in patients without culture (55%) than in patients with culture performed in practice (71%) or at hospital (69%). CONCLUSION: In a context with wide availability of diagnostic tests, GPs use diagnostic tests for the decision-making process in all patients with suspected UTI. Urine culture is used in the majority of the patients and is associated with a higher proportion of appropriate treatment decisions. Performance of urine culture is therefore important in reducing inappropriate antibiotic prescribing in patients with suspected UTI seeking care in general practice in Denmark.

Quality assessment in general practice: diagnosis and antibiotic treatment of acute respiratory tract infections.

OBJECTIVE: To investigate areas in need of quality improvement within the diagnostic process and antibiotic treatment of acute respiratory tract infections (RTIs) in Danish general practice by using quality indicators (QIs). DESIGN AND SETTING: During a 4-week period in winter 2017, a prospective registration of patients diagnosed with RTIs was conducted in general practice in two regions of Denmark. SUBJECTS: Throughout the registration period each patient with symptoms of an RTI was registered. Information about age, symptoms and findings, duration of symptoms, the use and result of clinical tests, allergy towards penicillin, referral to secondary care and the antibiotic given were recorded. MAIN OUTCOME MEASURES: Values and acceptable ranges for QIs focusing on the diagnostic process, the decision to prescribe antibiotics and the choice of antibiotics for patients with RTIs. RESULTS: Regarding the diagnostic process nearly all QIs for patients diagnosed with acute pharyngotonsillitis and pneumonia fell within the acceptable range. Contrarily, the diagnostic QIs for patients with acute otitis media and acute rhinosinusitis were outside the acceptable range. All indicators designed to measure overuse of antibiotics were outside the acceptable range and nearly all indicators assessing if patients were sufficiently treated fell within the acceptable range. QIs assessing use of the recommended type of antibiotic were only within the acceptable range for patients diagnosed with acute pharyngotonsillitis. CONCLUSION: The findings indicate an overuse of antibiotics for RTIs in Danish general practice. Especially management of acute rhinosinusitis and acute bronchitis should be targeted in future quality improvement projects. KEY POINTS: To improve antibiotic prescribing in general practice it is important to focus on both the diagnostic process and the prescribing patterns. The findings indicate an overuse of antibiotics for acute respiratory tract infections in Danish general practice. Especially the diagnostic process and antibiotic prescribing patterns for acute rhinosinusitis and acute bronchitis could benefit from future quality improvement interventions.

Identifying practice-related factors for high-volume prescribers of antibiotics in Danish general practice.

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.

Antibiotic prescriptions for suspected respiratory tract infection in primary care in South America.

OBJECTIVES: To describe and compare antibiotic prescribing patterns for primary care patients with respiratory tract infections (RTIs) in four South American countries. METHODS: This was a prospective observational study. General practitioners (GPs) from Argentina, Bolivia, Paraguay and Uruguay registered data about all consultations of patients with suspected RTIs in the winter of 2014 (June-August). Variation in antibiotic prescriptions was assessed using a two-level hierarchical logistic model. RESULTS: Participating GPs (n = 171) registered 11 446 patients with suspected RTI; 3701 (33%) of these received an antibiotic prescription. There was a wide variation across countries in the use and selection of antibiotics. For example, 94% of patients with acute bronchitis were prescribed antibiotics in Bolivia, while in Uruguay only 21% received antibiotics. Amoxicillin was the most commonly prescribed antibiotic across countries, but prescription rates varied between 45% in Bolivia and 69% in Uruguay. Compared with the overall mean prescribing rate, and after adjusting for clinical presentation and demographics, prescribing of antibiotics varied by a factor of 6, the OR ranging from 0.37 (95% CI = 0.21-0.65) in Uruguay to 2.58 (95% CI = 1.66-4) in Bolivia. CONCLUSIONS: The large variation in use and selection of antibiotics across countries is not explained by different patient populations. It could be explained by diagnostic uncertainty and contextual characteristics beyond clinical practice. Reducing uncertainty and country variation requires greater support from the healthcare systems by providing GPs with evidence-based guidelines and tools to apply them.

Prevalence of antimicrobial resistant Escherichia coli from patients with suspected urinary tract infection in primary care, Denmark.

BACKGROUND: Escherichia coli is the most common pathogen causing Urinary Tract Infections (UTI). Data from the current National Surveillance program in Denmark (DANMAP) may not accurately represent the prevalence of resistant E. coli in primary care, because only urine samples from complicated cases may be forwarded to the microbiological departments at hospitals for diagnostic examination. The aim of this study was to assess the prevalence of resistant E. coli to the most commonly used antimicrobial agents in primary care in a consecutive sample of patients from general practice. METHODS: Observational study carried out from December 2014 to December 2015. Thirty-nine general practices from The Capital Region of Denmark included adult patients with urinary tract symptoms and suspected UTI. All urine samples were sent to the central laboratory Statens Serum Institut (SSI). Significant bacteriuria was interpreted according to the European Urinalysis Standards. Susceptibility testing was performed and interpreted according to the European Committee on Antimicrobial Susceptibility Testing (EUCAST) standards. RESULTS: From the 39 general practices 505 patients were recruited. Completed data were obtained from 485 (96%) patients. According to the European Urinalysis Standards, 261 (54%) patients had positive bacteriuria. The most common uropathogen in patients with uncomplicated (uUTI) and complicated (cUTI) urinary tract infection was E. coli 105 (69%) and 76 (70%), respectively. Eighty-two (45%) of 181 E. coli isolates were resistant to at least one of the tested antibiotics and 50 out of 82 isolates were resistant to two or more antimicrobial agents. The highest resistance-rate was found against ampicillin 34% (95% CI 24;42) in uUTI and 36% (24;46) in cUTI. There were no differences in the distribution of resistance between uncomplicated and complicated cases. The prevalence of resistance was similar to the one reported in DANMAP 2014. CONCLUSION: In E. coli from uUTI there is high resistance rates to antimicrobial agents commonly used in primary care. There was no difference in the distribution of resistant E. coli in suspected uUTI vs cUTI. In Denmark, data from the National Surveillance program DANMAP can guide the decision for choice of antibiotic in patients with suspected UTI seeking care in primary care.

Microbiological point of care testing before antibiotic prescribing in primary care: considerable variations between practices.

BACKGROUND: Point-of-care testing (POCT) in primary care may improve rational antibiotic prescribing. We examined use of POCT in Denmark, including patient- and general practitioner (GP)-related predictors. METHODS: We linked nationwide health care databases to assess POCT use (C-reactive protein (CRP), group A streptococcal (GAS) antigen swabs, bacteriological cultures, and urine test strips) per 1,000 overall GP consultations, 2004-2013. We computed odds ratios (OR) of POCT in patients prescribed antibiotics according to patient and GP age and sex, GP practice type, location, and workload. RESULTS: The overall use of POCT in Denmark increased by 45.8% during 2004-2013, from 147.2 per 1,000 overall consultations to 214.8. CRP tests increased by 132%, bacteriological cultures by 101.7% while GAS swabs decreased by 8.6%. POCT preceded 28% of antibiotic prescriptions in 2004 increasing to 44% in 2013. The use of POCT varied more than 5-fold among individual practices, from 54.9 to 394.7 per 1,000 consultations in 2013. POCT use varied substantially with patient age, and males were less likely to receive POCT than females (adjusted OR = 0.75, 95% CI 0.74-0.75) driven by usage of urine test strips among females (18% vs. 7%). Odds of POCT were higher among female GPs and decreased with higher GP age, with lowest usage among male GPs >60 years. GP urban/rural location and workload had little impact. CONCLUSION: GPs use POCT increasingly with the highest use among young female GPs. In 2013, 44% of all antibiotic prescriptions were preceded by POCT but testing rates vary greatly across individual GPs.

Quality indicators for the diagnosis and antibiotic treatment of acute respiratory tract infections in general practice: a RAND Appropriateness Method.

OBJECTIVE: To develop quality indicators for the diagnosis and antibiotic treatment of acute respiratory tract infections, tailored to the Danish general practice setting. DESIGN: A RAND/UCLA Appropriateness Method was used. SETTING: General practice. SUBJECTS: A panel of nine experts, mainly general practitioners, was asked to rate the relevance of 64 quality indicators for the diagnosis and antibiotic treatment of acute respiratory tract infections based on guidelines. Subsequently, a face-to-face meeting was held to resolve misinterpretations and to achieve consensus. MAIN OUTCOME MEASURES: The experts were asked to rate the indicators on a nine-point Likert scale. Consensus of appropriateness for a quality indicator was reached if the overall panel median rating was 7-9 with agreement. RESULTS: A total of 50 of the 64 proposed quality indicators attained consensus. Consensus was achieved for 12 indicators focusing on the diagnostic process and 19 indicators focusing on the decision about antibiotic treatment and choice of antibiotics, respectively. CONCLUSION: These newly developed quality indicators may be used to strengthen Danish general practitioners' focus on their management of patients with acute respiratory tract infections and to identify where there is a need for future quality improvements.

Clinical indications for antibiotic use in Danish general practice: results from a nationwide electronic prescription database.

OBJECTIVE: To assess the availability and applicability of clinical indications from electronic prescriptions on antibiotic use in Danish general practice. DESIGN: Retrospective cohort register-based study including the Danish National Prescription Register. SETTING: Population-based study of routine electronic antibiotic prescriptions from Danish general practice. SUBJECTS: All 975,626 patients who redeemed an antibiotic prescription at outpatient pharmacies during the 1-year study period (July 2012 to June 2013). MAIN OUTCOME MEASURES: Number of prescriptions per clinical indication. Number of antibiotic prescriptions per 1000 inhabitants by age and gender. Logistic regression analysis estimated the association between patient and provider factors and missing clinical indications on antibiotic prescriptions. RESULTS: A total of 2.381.083 systemic antibiotic prescriptions were issued by Danish general practitioners in the study period. We identified three main clinical entities: urinary tract infections (n = 506.634), respiratory tract infections (n = 456.354) and unspecified infections (n = 416.354). Women were more exposed to antibiotics than men. Antibiotic use was high in children under 5 years and even higher in elderly people. In 32% of the issued prescriptions, the clinical indication was missing. This was mainly associated with antibiotic types. We found that a prescription for a urinary tract agent without a specific clinical indication was uncommon. CONCLUSION: Clinical indications from electronic prescriptions are accessible and available to provide an overview of drug use, in casu antibiotic prescriptions, in Danish general practice. These clinical indications may be further explored in detail to assess rational drug use and congruence with guidelines, but validation and optimisation of the system is preferable.
