Antibiotics for the common cold and acute purulent rhinitis

User initiated symptom assessment with an electronic symptom checker. Study protocol for mixed-methods validation. (Preprint)

BACKGROUND

The national Omaolo digital social welfare and health care service of Finland provides a symptom checker, Omaolo, which is a medical device (based on Duodecim Clinical Decision Support EBMEDS software) with a CE marking (risk class IIa), manufactured by the government-owned DigiFinland Oy. Users of this service can perform their triage by using the questions in the symptom checker. By completing the symptom checker, the user receives a recommendation for action and a service assessment with appropriate guidance regarding their health problems on the basis of a selected specific symptom in the symptom checker. This allows users to be provided with appropriate health care services, regardless of time and place.

OBJECTIVE

This study describes the protocol for the mixed methods validation process of the symptom checker available in Omaolo digital services.

METHODS

This is a mixed methods study using quantitative and qualitative methods, which will be part of the clinical validation process that takes place in primary health care centers in Finland. Each organization provides a space where the study and the nurse triage can be done in order to include an unscreened target population of users. The primary health care units provide walk-in model services, where no prior phone call or contact is required. For the validation of the Omaolo symptom checker, case vignettes will be incorporated to supplement the triage accuracy of rare and acute cases that cannot be tested extensively in real-life settings. Vignettes are produced from a variety of clinical sources, and they test the symptom checker in different triage levels by using 1 standardized patient case example.

RESULTS

This study plan underwent an ethics review by the regional permission, which was requested from each organization participating in the research, and an ethics committee statement was requested and granted from Pirkanmaa hospital district's ethics committee, which is in accordance with the University of Tampere's regulations. Of 964 clinical user-filled symptom checker assessments, 877 cases were fully completed with a triage result, and therefore, they met the requirements for clinical validation studies. The goal for sufficient data has been reached for most of the chief symptoms. Data collection was completed in September 2019, and the first feasibility and patient experience results were published by the end of 2020. Case vignettes have been identified and are to be completed before further testing the symptom checker. The analysis and reporting are estimated to be finalized in 2024.

CONCLUSIONS

The primary goals of this multimethod electronic symptom checker study are to assess safety and to provide crucial information regarding the accuracy and usability of the Omaolo electronic symptom checker. To our knowledge, this will be the first study to include real-life clinical cases along with case vignettes.

Treatment of the most common respiratory infections in children

Acute respiratory infections are the most common group of infective diseases in the pediatric population. Although the improvement of health care and vaccination program has led to a significant reduction in the incidence of certain respiratory infections, the combination of a high prevalence in vulnerable pediatric categories and uncritical prescription of antibiotics, due to the inability to adequately distinguish between viruses and bacterial etiology, still represents a significant challenge for the public health system. In order to promote rational antibiotic therapy with an overall improvement of both diagnostic and therapeutic principles, acute respiratory diseases have been the subject of consideration in numerous publications and national guidelines. Nonspecific clinical manifestations with pathogen heterogeneity and both anatomical and physiological characteristics of the child's respiratory system during growth and development have created the need for individualized therapy. Since the guidelines emphasize the undoubtful and crucial benefits of symptomatic therapy (e.g. analgesics in acute otitis media, supplemental oxygen in lower respiratory tract infections with hypoxemia), the use of antibiotics and corticosteroids is indicated in selected cases with a severe clinical picture. The choice of antibiotic depends on the clinical condition, presumed causative agent, and local epidemiologic circumstances. Respiratory support (oxygen therapy and/or artificial ventilation) is reserved for inpatient treatment of cases with a particularly severe clinical picture and associated complications.

Association between Physicians' Perception of Shared Decision Making with Antibiotic Prescribing Behavior in Primary Care in Hubei, China: A Cross-Sectional Study

Shared decision-making (SDM) has been advocated as one effective strategy for improving physician–patient relationships and optimizing clinical outcomes. Our study aimed to measure physicians’ perception of SDM and establish the relationship between physicians’ perception of SDM and prescribing behavior in patients with upper respiratory tract infections. One cross-sectional study was conducted in Hubei Province from December 2019 to January 2020. The SDM questionnaire and prescription data of 2018 from electronic health records data were matched for each physician in this study. Multilevel modeling was applied to explore the relationship between physicians’ perception of SDM and antibiotic prescribing in primary care. Analyses were statistically controlled for demographic characteristics of the physicians and patients. Physicians’ positive perception of SDM had small but statistically significant effects on lower prescribing of antibiotics in the patient group aged over 40 years (odds ratio (OR) < 1; p < 0.05). Moreover, female physicians (OR = 0.71; p = 0.007) with higher educational levels (bachelor’s degree and above; OR = 0.71; p = 0.024) were significantly associated with the prescribing of less antibiotics (p < 0.05). A more positive perception of SDM was demonstrated as one significant predictor of less prescribing of antibiotics in the patient group over 40 years. There may be a promising focus of implementing SDM strategies targeting physician–patient communication in primary care.

Is sharing the TARGET respiratory tract infection leaflet feasible in routine general practice to improve patient education and appropriate antibiotic use? A mixed methods study in England with patients and healthcare professionals

BACKGROUND

Patient education on treatment choices for common respiratory tract infections (RTIs) is important to encourage appropriate antibiotic use. Evidence shows that use of leaflets about RTIs can help reduce antibiotic prescribing. TARGET leaflets facilitate patient-clinician communication in consultations.

AIM

To explore patient, healthcare professional (HCP) and general practice (GP) staff views on the current Treating Your Infection (TYI)-RTI leaflet and proposed new 'antibiotic effect' column aimed at sharing information on the limited effect antibiotics have on the duration of RTIs.

METHODS

Service evaluation underpinned by Com-B behavioural framework, using patient and HCP questionnaires, and GP staff interviews/focus groups.

RESULTS

Patients completed 83 questionnaires in GP waiting rooms. A lack of patient understanding about usual illness duration influenced their use of antibiotics for some RTIs. Patients provided positive feedback about the leaflet, reporting it increased their capability to self-care, re-consult when necessary and increase understanding of illness duration. Patients indicated they would value information on the difference antibiotics can make to illness duration. In total, 43 HCP questionnaires were completed and 16 GP staff participated in interviews/focus groups. Emerging themes included: barriers and facilitators to leaflet use; modifications; and future dissemination of the leaflet. GP staff stated that the 'antibiotic effect' column should not be included in the leaflet.

CONCLUSION

Patient education around usual illness duration, side effects of antibiotics and back-up prescriptions gives patients a greater control of their infection management. As GP staff opposed the extra information about benefits of antibiotics on illness duration, this will not be added.

Prescription of Systemic Steroids for Acute Respiratory Infections in Korean Outpatient Settings: Overall Patterns and Effects of the Prescription Appropriateness Evaluation Policy

OBJECTIVES

The objective of this study was to identify individual and institutional factors associated with the prescription of systemic steroids in patients with acute respiratory infections and to investigate the role of a policy measure aimed to reduce inappropriate prescriptions.

METHODS

We used data from the National Health Insurance Service-National Sample Cohort from 2006 to 2015 and focused on episodes of acute respiratory infection. Descriptive analysis and multiple logistic regression analysis were performed to identify individual-level and institution-level factors associated with the prescription of systemic steroids. In addition, steroid prescription rates were compared with antibiotic prescription rates to assess their serial trends in relation to Health Insurance Review and Assessment Service (HIRA) Prescription Appropriateness Evaluation policy.

RESULTS

Among a total of 9 460 552 episodes of respiratory infection, the steroid prescription rate was 6.8%. Defined daily doses/1000 persons/d of steroid increased gradually until 2009, but rose sharply since 2010. The steroid prescription rate was higher among ear, nose and throat specialties (13.0%) than other specialties, and in hospitals (8.0%) than in tertiary hospitals (3.0%) and other types of institutions. Following a prolonged reduction in the steroid prescription rate, this rate increased since the HIRA Prescription Appropriateness Evaluation dropped steroids from its list of evaluation items in 2009. Such a trend reversal was not observed for the prescription rate of antibiotics, which continue to be on the HIRA Prescription Appropriateness Evaluation list.

CONCLUSIONS

Specialty and type of institution are important correlates of steroid prescriptions in cases of acute respiratory infection. Steroid prescriptions can also be influenced by policy measures, such as the HIRA Prescription Appropriateness Evaluation policy.

A review on the therapeutic effects of NetiKriya with special reference to JalaNeti

Neti kriya is an integral part of shatkarmas/the six cleansing techniques that form the most important aspect of hatha yoga. Neti helps in preventing and managing upper respiratory tract diseases. An attempt is being made to collate and review articles that highlight the therapeutic effects of neti kriya. Databases like PubMed (January 1980–April 2016), Scopus and Ayush Portal were searched. We used keywords like jala neti, neti kriya, neti combined with terms such as yoga, sinusitis, rhinitis, common cold, vision, snoring, nasopharyngeal carcinoma and mental health for the search. As only a few results were obtained, we reviewed relevant studies with saline nasal irrigation. Evidence emerging from this review suggests that neti offers manifold benefits and relief from the antibiotic grip. Most studies support the role of neti in treating sinusitis, rhinosinusitis, allergic conditions and in improving vision. Jala neti has a significant role in improving the presence of mind and intelligence. We identified that it can be applied in mitigating post irradiation rhinosinusitis in nasopharyngeal carcinoma. However, randomized control trials must be conducted to substantiate the therapeutic efficacy of this simple cost-effective, non-pharmacological mode of treatment.

Prescription and non-prescription antibiotic dispensing practices in part I and part II pharmacies in Moshi Municipality, Kilimanjaro Region in Tanzania: A simulated clients approach

Antibiotic dispensing without a prescription poses a threat to public health as it leads to excessive antibiotic consumption. Inappropriate antibiotic availability to the community has been documented to be amongst drivers of antimicrobial resistance emergence. Community pharmacies are a source of antibiotics in low and middle-income countries (LMICs). We aimed at assessing antibiotic dispensing practices by community pharmacy retailers in Moshi urban, Kilimanjaro, Tanzania and recommend interventions to improve practice. Using a Simulated Client (SC) Method, an observational cross-sectional survey of antibiotic dispensing practices was conducted from 10th June to 10th July 2017. Data analysis was done using Stata 13 (StataCorp, College Station, TX, USA). A total of 82 pharmacies were visited. Part I pharmacies were 26 (31.71%) and 56 (68.29%) were part II. Overall 92.3% (95% CI 77.8-97.6) of retailers dispensed antibiotics without prescriptions. The antibiotics most commonly dispensed without a prescription were ampiclox for cough (3 encounters) and azithromycin for painful urination (3 encounters). An oral third generation cephalosporin (cefixime) was dispensed once for painful urination without prescription by a part I pharmacy retailer. Out of 21, 15(71.43%) prescriptions with incomplete doses were accepted and had antibiotics dispensed. Out of 68, 4(5.9%) retailers gave instructions for medicine use voluntarily. None of the retailers voluntarily explained drug side-effects. In Moshi pharmacies, a high proportion of antibiotics are sold and dispensed without prescriptions. Instructions for medicine use are rarely given and none of the retailers explain side effects. These findings support the need for a legislative enforcement of prescription-only antibiotic dispensing rules and regulations. Initiation of clinician and community antibiotic stewardship and educational programs on proper antibiotic use to both pharmacists and public by the regulatory bodies are highly needed.

Antibiotics for prolonged wet cough in children

BACKGROUND

Cough is a frequent symptom presenting to doctors. The most common cause of childhood chronic (greater than fours weeks' duration) wet cough is protracted bacterial bronchitis (PBB) in some settings, although other more serious causes can also present this way. Timely and effective management of chronic wet or productive cough improves quality of life and clinical outcomes. Current international guidelines suggest a course of antibiotics is the first treatment of choice in the absence of signs or symptoms specific to an alternative diagnosis. This review sought to clarify the current evidence to support this recommendation.

OBJECTIVES

To determine the efficacy of antibiotics in treating children with prolonged wet cough (excluding children with bronchiectasis or other known underlying respiratory illness) and to assess risk of harm due to adverse events.

SEARCH METHODS

We undertook an updated search (from 2008 onwards) using the Cochrane Airways Group Specialised Register, Cochrane Register of Controlled Trials (CENTRAL), MEDLINE, Embase, trials registries, review articles and reference lists of relevant articles. The latest searches were performed in September 2017.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) comparing antibiotics with a placebo or a control group in children with chronic wet cough. We excluded cluster and cross-over trials.

DATA COLLECTION AND ANALYSIS

We used standard methods as recommended by Cochrane. We reviewed results of searches against predetermined criteria for inclusion. Two independent review authors selected, extracted and assessed the data for inclusion. We contacted authors of eligible studies for further information as needed. We analysed data as 'intention to treat.'

MAIN RESULTS

We identified three studies as eligible for inclusion in the review. Two were in the previous review and one new study was included. We considered the older studies to be at high or unclear risk of bias whereas we judged the newly included study at low risk of bias. The studies varied in treatment duration (from 7 to 14 days) and the antibiotic used (two studies used amoxicillin/clavulanate acid and one used erythromycin).We included 190 children (171 completed), mean ages ranged from 21 months to six years, in the meta-analyses. Analysis of all three trials (190 children) found that treatment with antibiotics reduced the proportion of children not cured at follow-up (primary outcome measure) (odds ratio (OR) 0.15, 95% confidence interval (CI) 0.07 to 0.31, using intention-to -treat analysis), which translated to a number needed to treat for an additional beneficial outcome (NNTB) of 3 (95% CI 2 to 4). We identified no significant heterogeneity (for both fixed-effect and random-effects model the I² statistic was 0%). Two older trials assessed progression of illness, defined by requirement for further antibiotics (125 children), which was significantly lower in the antibiotic group (OR 0.10, 95% CI 0.03 to 0.34; NNTB 4, 95% CI 3 to 5). All three trials (190 children) reported adverse events, which were not significantly increased in the antibiotic group compared to the control group (OR 1.88, 95% CI 0.62 to 5.69). We assessed the quality of evidence GRADE rating as moderate for all outcome measures, except adverse events which we assessed as low quality.

AUTHORS' CONCLUSIONS

Evidence suggests antibiotics are efficacious for the treatment of children with chronic wet cough (greater than four weeks) with an NNTB of three. However, antibiotics have adverse effects and this review reported only uncertainty as to the risk of increased adverse effects when they were used in this setting. The inclusion of a more robust study strengthened the previous Cochrane review and its results.

Clinical Practice Guideline: Hoarseness (Dysphonia) (Update)

Objective

This guideline provides evidence-based recommendations on treating patients who present with dysphonia, which is characterized by altered vocal quality, pitch, loudness, or vocal effort that impairs communication and/or quality of life. Dysphonia affects nearly one-third of the population at some point in its life. This guideline applies to all age groups evaluated in a setting where dysphonia would be identified or managed. It is intended for all clinicians who are likely to diagnose and treat patients with dysphonia.

Purpose

The primary purpose of this guideline is to improve the quality of care for patients with dysphonia, based on current best evidence. Expert consensus to fill evidence gaps, when used, is explicitly stated and supported with a detailed evidence profile for transparency. Specific objectives of the guideline are to reduce inappropriate variations in care, produce optimal health outcomes, and minimize harm. For this guideline update, the American Academy of Otolaryngology—Head and Neck Surgery Foundation selected a panel representing the fields of advanced practice nursing, bronchoesophagology, consumer advocacy, family medicine, geriatric medicine, internal medicine, laryngology, neurology, otolaryngology–head and neck surgery, pediatrics, professional voice, pulmonology, and speech-language pathology.

Action Statements

The guideline update group made strong recommendations for the following key action statements (KASs): (1) Clinicians should assess the patient with dysphonia by history and physical examination to identify factors where expedited laryngeal evaluation is indicated. These include, but are not limited to, recent surgical procedures involving the head, neck, or chest; recent endotracheal intubation; presence of concomitant neck mass; respiratory distress or stridor; history of tobacco abuse; and whether the patient is a professional voice user. (2) Clinicians should advocate voice therapy for patients with dysphonia from a cause amenable to voice therapy. The guideline update group made recommendations for the following KASs: (1) Clinicians should identify dysphonia in a patient with altered voice quality, pitch, loudness, or vocal effort that impairs communication or reduces quality of life (QOL). (2) Clinicians should assess the patient with dysphonia by history and physical examination for underlying causes of dysphonia and factors that modify management. (3) Clinicians should perform laryngoscopy, or refer to a clinician who can perform laryngoscopy, when dysphonia fails to resolve or improve within 4 weeks or irrespective of duration if a serious underlying cause is suspected. (4) Clinicians should perform diagnostic laryngoscopy, or refer to a clinician who can perform diagnostic laryngoscopy, before prescribing voice therapy and document/communicate the results to the speech-language pathologist (SLP). (5) Clinicians should advocate for surgery as a therapeutic option for patients with dysphonia with conditions amenable to surgical intervention, such as suspected malignancy, symptomatic benign vocal fold lesions that do not respond to conservative management, or glottic insufficiency. (6) Clinicians should offer, or refer to a clinician who can offer, botulinum toxin injections for the treatment of dysphonia caused by spasmodic dysphonia and other types of laryngeal dystonia. (7) Clinicians should inform patients with dysphonia about control/preventive measures. (8) Clinicians should document resolution, improvement or worsened symptoms of dysphonia, or change in QOL of patients with dysphonia after treatment or observation. The guideline update group made a strong recommendation against 1 action: (1) Clinicians should not routinely prescribe antibiotics to treat dysphonia. The guideline update group made recommendations against other actions: (1) Clinicians should not obtain computed tomography (CT) or magnetic resonance imaging (MRI) for patients with a primary voice complaint prior to visualization of the larynx. (2) Clinicians should not prescribe antireflux medications to treat isolated dysphonia, based on symptoms alone attributed to suspected gastroesophageal reflux disease (GERD) or laryngopharyngeal reflux (LPR), without visualization of the larynx. (3) Clinicians should not routinely prescribe corticosteroids for patients with dysphonia prior to visualization of the larynx. The policy level for the following recommendation about laryngoscopy at any time was an option: (1) Clinicians may perform diagnostic laryngoscopy at any time in a patient with dysphonia.

Disclaimer

This clinical practice guideline is not intended as an exhaustive source of guidance for managing dysphonia (hoarseness). Rather, it is designed to assist clinicians by providing an evidence-based framework for decision-making strategies. The guideline is not intended to replace clinical judgment or establish a protocol for all individuals with this condition, and it may not provide the only appropriate approach to diagnosing and managing this problem. Differences from Prior Guideline (1) Incorporation of new evidence profiles to include the role of patient preferences, confidence in the evidence, differences of opinion, quality improvement opportunities, and any exclusion to which the action statement does not apply (2) Inclusion of 3 new guidelines, 16 new systematic reviews, and 4 new randomized controlled trials (3) Inclusion of a consumer advocate on the guideline update group (4) Changes to 9 KASs from the original guideline (5) New KAS 3 (escalation of care) and KAS 13 (outcomes) (6) Addition of an algorithm outlining KASs for patients with dysphonia

The effect of interventions aiming to optimise the prescription of antibiotics in dental care-A systematic review

BACKGROUND

Abundant evidence in dentistry suggests that antibiotics are prescribed despite the existence of guidelines aiming to reduce the development of antibiotic resistance. This review investigated (1) which type of interventions aiming to optimise prescription of antibiotics exist in dentistry, (2) the effect of these interventions and (3) the specific strengths and limitations of the studies reporting on these interventions.

METHOD

Literature search was based on Medline, Embase, Global Health, Cochrane CENTRAL, ClinicalTrials.gov and Current Controlled Trials. Studies with one of the two primary outcomes were included: (1) The number of antibiotics prescribed and/or (2) the accuracy of the prescription, commonly measured as a percentage of adherence to local clinical guidelines.

RESULTS

Nine studies met these inclusion criteria. Five studies reported on the prescription of antibiotics in primary dental care and four studies focused on outpatient dental care. Interventions used in primary dental care included a combination of audit, feedback, education, local consensus, dissemination of guidelines and/or academic detailing. Trials in the outpatient setting made use of expert panel discussions, educational feedback on previous acts of prescribing, the dissemination of guidelines and the establishment of internal guidelines. All studies successfully reduced the number of antibiotics prescribed and/or increased the accuracy of the prescription. However, most studies were confounded by a high risk of selection bias, selective outcome reporting and high variance across study groups. In particular, information relating to study design and methodology was insufficient. Only three studies related the prescriptions to the number of patients treated with antibiotics.

CONCLUSIONS

This systematic review was able to offer conclusions which took the limitations of the investigated studies into account. Unfortunately, few studies could be included and many of these studies were confounded by a low quality of scientific reporting and lack of information regarding study methodology. High-quality research with objective and standardised outcome reporting, longer periods of follow-up, rigorous methodology and adequate standard of study reporting is urgently needed.

E-health and consultation rates for respiratory illnesses in infants: a randomised clinical trial in primary care

BACKGROUND

It is assumed that clear and complete information on the internet can reduce healthcare consumption.

AIM

We assessed in a randomised clinical trial whether a personalised online parent information program on infant respiratory symptoms can reduce primary care utilisation.

DESIGN AND SETTING

Randomised clinical trial in primary healthcare centres in a new residential area in the Netherlands.

METHOD

A web-based program (WHISTLER-online) was developed for parents that offered general information on childhood respiratory disease and personalised risk assessments. Parents of infants who enrolled from June 2009 to June 2012 in WHISTLER, an ongoing population-based birth cohort, were randomly allocated to 'WHISTLER-online' or 'usual care'. Information about, first, consultations and, second, associated prescriptions for respiratory symptoms during the first year of life was collected from the electronic patient files.

RESULTS

A total of 323 infants were randomly assigned to WHISTLER-online and 322 to usual care, and 314 and 305, respectively, were analysed. Of the parents, 70% used WHISTLER-online, and 99% of them judged it to be clear and useful information. There were differences neither in consultation rates for respiratory symptoms (incidence rate ratio 0.96 [95% CI = 0.85 to 1.09, P = 0.532]) nor in associated drug prescriptions.

CONCLUSION

Although parents greatly appreciate the provided facilities, a personalised e-support program on respiratory illnesses in infants does not substantially reduce healthcare utilisation.

A mixed methods study to understand patient expectations for antibiotics for an upper respiratory tract infection

Background

Antimicrobial resistance is a public health challenge supplemented by inappropriate prescribing, especially for an upper respiratory tract infection in primary care. Patient/carer expectations have been identified as one of the main drivers for inappropriate antibiotics prescribing by primary care physicians. The aim of this study was to understand who is more likely to expect an antibiotic for an upper respiratory tract infection from their doctor and the reasons underlying it.

Methods

This study used a sequential mixed methods approach: a nationally representative cross sectional survey (n = 1509) and four focus groups. The outcome of interest was expectation and demand for an antibiotic from a doctor when presenting with a cold or flu.

Results

The study found 19.5 % of survey respondents reported that they would expect the doctor to prescribe antibiotics for a cold or flu. People younger than 65 years of age, those who never attended university and those speaking a language other than English at home were more likely to expect or demand antibiotics for a cold or flu. People who knew that ‘antibiotics don’t kill viruses’ and agreed that ‘taking an antibiotic when one is not needed means they won’t work in the future’ were less likely to expect or demand antibiotics. The main reasons for expecting antibiotics were believing that antibiotics are an effective treatment for a cold or flu and that they shortened the duration and potential deterioration of their illness. The secondary reason centered around the value or return on investment for visiting a doctor when feeling unwell.

Conclusion

Our study found that patients do not appear to feel they have a sufficiently strong incentive to consider the impact of their immediate use of antibiotics on antimicrobial resistance. The issue of antibiotic resistance needs to be explained and reframed as a more immediate health issue with dire consequences to ensure the success of future health campaigns.

Cost-Effectiveness of Decision Support Strategies in Acute Bronchitis

BACKGROUND

A recent clinical trial suggests that printed (PDS) and computer decision support (CDS) interventions are safe and effective in reducing antibiotic use in acute bronchitis relative to usual care (UC).

OBJECTIVE

Our aim was to evaluate the cost-effectiveness of decision support interventions in reducing antibiotic use in acute bronchitis.

DESIGN

We conducted a clinical trial-based cost-effectiveness analysis comparing UC, PDS and CDS for management of acute bronchitis. We assumed a societal perspective, 5-year program duration and 30-day time horizon.

PATIENTS

The U.S. population aged 13-64 years presenting with acute bronchitis in the ambulatory setting.

INTERVENTIONS

Printed and computer decision support interventions relative to usual care.

MAIN MEASURES

Cost per antibiotic prescription safely avoided.

KEY RESULTS

In the base case, PDS dominated UC and CDS, with lesser total costs (PDS: $2,574, UC: $2,768, CDS: $2,805) and fewer antibiotic prescriptions (PDS: 3.79, UC: 4.60, CDS: 3.95) per patient over 5 years. In one-way sensitivity analyses, PDS dominated UC across all parameter values, except when antibiotics reduced work loss by ≥ 1.9 days or the probability of hospitalization within 30 days was ≥ 0.9 % in PDS (base case: 0.2 %) or ≤ 0.4 % in UC (base case: 1.0 %). The dominance of PDS over CDS was sensitive both to probability of hospitalization and plausible variation in the adjusted odds of antibiotic use in both strategies.

CONCLUSIONS

A PDS strategy to reduce antibiotic use in acute bronchitis is less costly and more effective than both UC and CDS strategies, although results were sensitive to variation in probability of hospitalization and the adjusted odds of antibiotic use. This simple, low-cost, safe, and effective intervention would be an economically reasonable component of a multi-component approach to address antibiotic overuse in acute bronchitis.

A systematic review of parent and clinician views and perceptions that influence prescribing decisions in relation to acute childhood infections in primary care

OBJECTIVES

To investigate the views of parents, clinicians, and children pertaining to prescribing decisions for acute childhood infection in primary care.

METHODS

A systematic review of qualitative studies. Meta-ethnographic methods were used, with data drawn from the primary studies in an interpretive analysis.

RESULTS

A total of 15 studies met the inclusion criteria. The literature was dominated by concerns about antibiotic over-prescription. Children's views were not reported. Clinicians prescribed antibiotics when they felt pressured by parents or others (e.g. employers) to do so, when they believed there was a clear clinical indication, but also when they felt uncertain of clinical or social outcomes they prescribed "just in case". Parents wanted antibiotics when they felt they would improve the current illness, and when they felt pressure from daycare providers or employers. Clinicians avoided antibiotics when they were concerned about adverse reactions or drug resistance, when certain they were not indicated, and when there was no perceived pressure from parents. Parents also wished to avoid adverse effects of antibiotics, and did not want antibiotics when they would not relieve current symptoms. Some parents preferred to avoid medication altogether. Within paediatric consultations, parents sought a medical evaluation and decision. Primary care clinicians want satisfied parents and short consultations.

CONCLUSIONS

Antibiotic prescriptions for childhood infections in primary care often result from "just in case" prescribing. These findings suggest that interventions which reduce clinician uncertainty regarding social or clinical outcomes and provide strategies to meet parents' needs within a short consultation are most likely to reduce antibiotic prescribing.

Clinical and haematological predictors of antibiotic prescribing for acute cough in adults in Swiss practices--an observational study

Background

Acute cough is a common problem in general practice and is often caused by a self-limiting, viral infection. Nonetheless, antibiotics are often prescribed in this situation, which may lead to unnecessary side effects and, even worse, the development of antibiotic resistant microorganisms worldwide. This study assessed the role of point-of-care C-reactive protein (CRP) testing and other predictors of antibiotic prescription in patients who present with acute cough in general practice.

Methods

Patient characteristics, symptoms, signs, and laboratory and X-ray findings from 348 patients presenting to 39 general practitioners with acute cough, as well as the GPs themselves, were recorded by fourth-year medical students during their three-week clerkships in general practice. Patient and clinician characteristics of those prescribed and not-prescribed antibiotics were compared using a mixed-effects model.

Results

Of 315 patients included in the study, 22% were prescribed antibiotics. The two groups of patients, those prescribed antibiotics and those treated symptomatically, differed significantly in age, demand for antibiotics, days of cough, rhinitis, lung auscultation, haemoglobin level, white blood cell count, CRP level and the GP’s license to self-dispense antibiotics. After regression analysis, only the CRP level, the white blood cell count and the duration of the symptoms were statistically significant predictors of antibiotic prescription.

Conclusions

The antibiotic prescription rate of 22% in adult patients with acute cough in the Swiss primary care setting is low compared to other countries. GPs appear to use point-of-care CRP testing in addition to the duration of clinical symptoms to help them decide whether or not to prescribe antibiotics.

Public reporting improves antibiotic prescribing for upper respiratory tract infections in primary care: a matched-pair cluster-randomized trial in China

BACKGROUND

Inappropriate use and overuse of antibiotics is a serious concern in the treatment of upper respiratory tract infections (URTIs), especially in developing countries. In recent decades, information disclosure and public reporting (PR) has become an instrument for encouraging good practice in healthcare. This study evaluated the impact of PR on antibiotic prescribing for URTIs in a sample of primary care institutions in China.

METHODS

A matched-pair cluster-randomized trial was undertaken in QJ city, with 20 primary care institutions participating in the trial. Participating institutions were matched into pairs before being randomly assigned into a control and an intervention group. Prescription statistics were disclosed to patients, health authorities, and health workers monthly within the intervention group, starting from October 2013. Outpatient prescriptions for URTIs were collected from both groups before (1st March to 31st May, 2013) and after the intervention (1st March to 31st May, 2014). A total of 34,815 URTI prescriptions were included in a difference-in-difference analysis using multivariate linear or logistic regression models, controlling for patient attributes as well as institutional characteristics.

RESULTS

Overall, 90% URTI prescriptions required antibiotics and 21% required combined use of antibiotics. More than 77% of URTI prescriptions required intravenous (IV) injection or infusion of drugs. PR resulted in a 9 percentage point (95% CI -17 to -1) reduction in the use of oral antibiotics (adjusted RR = 39%, P = 0.027), while the use of injectable antibiotics remained unchanged. PR led to a 7 percentage point reduction (95% CI -14 to 0; adjusted RR = 36%) in combined use of antibiotics (P = 0.049), which was largely driven by a significant reduction in male patients (-7.5%, 95% CI -14 to -1, P = 0.03). The intervention had little impact on the use of IV injections or infusions, or the total prescription expenditure.

CONCLUSIONS

The results suggest that PR could improve prescribing practices in terms of reducing oral antibiotics and combined use of antibiotics; however, the impacts were limited. We suggest that PR would probably be enhanced by provider payment reform, management and training for providers, and health education for patients.

Effects of computer-aided clinical decision support systems in improving antibiotic prescribing by primary care providers: a systematic review

OBJECTIVE

To assess the effectiveness of computer-aided clinical decision support systems (CDSS) in improving antibiotic prescribing in primary care.

METHODS

A literature search utilizing Medline (via PubMed) and Embase (via Embase) was conducted up to November 2013. Randomized controlled trials (RCTs) and cluster randomized trials (CRTs) that evaluated the effects of CDSS aiming at improving antibiotic prescribing practice in an ambulatory primary care setting were included for review. Two investigators independently extracted data about study design and quality, participant characteristics, interventions, and outcomes.

RESULTS

Seven studies (4 CRTs, 3 RCTs) met our inclusion criteria. All studies were performed in the USA. Proportions of eligible patient visits that triggered CDSS use varied substantially between intervention arms of studies (range 2.8-62.8%). Five out of seven trials showed marginal to moderate statistically significant effects of CDSS in improving antibiotic prescribing behavior. CDSS that automatically provided decision support were more likely to improve prescribing practice in contrast to systems that had to be actively initiated by healthcare providers.

CONCLUSIONS

CDSS show promising effectiveness in improving antibiotic prescribing behavior in primary care. Magnitude of effects compared to no intervention, appeared to be similar to other moderately effective single interventions directed at primary care providers. Additional research is warranted to determine CDSS characteristics crucial to triggering high adoption by providers as a perquisite of clinically relevant improvement of antibiotic prescribing.

Cost-effectiveness of procalcitonin-guided antibiotic therapy for outpatient management of acute respiratory tract infections in adults

BACKGROUND

Two clinical trials suggest that procalcitonin-guided antibiotic therapy can safely reduce antibiotic prescribing in outpatient management of acute respiratory tract infections (ARTIs) in adults. Yet, it remains unclear whether procalcitonin testing is cost-effective in this setting.

OBJECTIVE

To evaluate the cost-effectiveness of procalcitonin-guided antibiotic therapy in outpatient management of ARTIs in adults.

DESIGN

Cost-effectiveness model based on results from two published European clinical trials, with all parameters varied widely in sensitivity analyses.

PATIENTS

Two hypothetical cohorts were modeled in separate trial-based analyses: adults with ARTIs judged by their physicians to require antibiotics and all adults with ARTIs.

INTERVENTIONS

Procalcitonin-guided antibiotic therapy protocols versus usual care.

MAIN MEASURES

Costs and cost per antibiotic prescription safely avoided.

KEY RESULTS

We estimated the health care system willingness-to-pay threshold as $43 (range $0–$333) per antibiotic safely avoided, reflecting the estimated cost of antibiotic resistance per outpatient antibiotic prescribed. In the cohort including all adult ARTIs judged to require antibiotics by their physicians, procalcitonin cost $31 per antibiotic prescription safely avoided and the likelihood of procalcitonin use being favored compared to usual care was 58.4 % in a probabilistic sensitivity analysis. In the analysis that included all adult ARTIs, procalcitonin cost $149 per antibiotic prescription safely avoided and the likelihood of procalcitonin use being favored was 2.8 %.

CONCLUSIONS

Procalcitonin-guided antibiotic therapy for outpatient management of ARTIs in adults would be cost-effective when the costs of antibiotic resistance are considered and procalcitonin testing is limited to adults with ARTIs judged by their physicians to require antibiotics.

Use of text messages to communicate clinical recommendations to health workers in rural China: a cluster-randomized trial

OBJECTIVE

To compare the effectiveness of mobile phone text messaging and that of traditional health worker training in communicating clinical recommendations to health workers in China.

METHODS

A cluster-randomized controlled trial (Chinese Clinical Trial Register: ChiCTR-TRC-09000488) was conducted in 100 township health centres in north-western China between 17 October and 25 December 2011. Health workers were allocated either to receive 16 text messages with recommendations on the management of viral infections affecting the upper respiratory tract and otitis media (intervention group, n = 490) or to receive the same recommendations through the existing continuing medical education programme - a one-day training workshop (control group, n = 487). Health workers' knowledge of the recommendations was assessed before and after messaging and traditional training through a multiple choice questionnaire. The percentage change in score in the control group was compared with that in the intervention group. Changes in prescribing practices were also compared.

FINDINGS

Health workers' knowledge of the recommendations increased significantly in the intervention group, both individually (0.17 points; 95% confidence interval, CI: 0.168-0.172) and at the cluster level (0.16 points; 95% CI: 0.157-0.163), but not in the control group. In the intervention group steroid prescriptions decreased by 5 percentage points but antibiotic prescriptions remained unchanged. In the control group, however, antibiotic and steroid prescriptions increased by 17 and 11 percentage points, respectively.

CONCLUSION

Text messages can be effective for transmitting medical information and changing health workers' behaviour, particularly in resource-limited settings.

Assessing the construct validity and reliability of the Parental Perception on Antibiotics (PAPA) scales

BACKGROUND

The overuse of antibiotics is becoming an increasing concern. Antibiotic resistance, which increases both the burden of disease, and the cost of health services, is perhaps the most profound impact of antibiotics overuse. Attempts have been made to develop instruments to measure the psychosocial constructs underlying antibiotics use, however, none of these instruments have undergone thorough psychometric validation. This study evaluates the psychometric properties of the Parental Perceptions on Antibiotics (PAPA) scales. The PAPA scales attempt to measure the factors influencing parental use of antibiotics in children.

METHODS

1111 parents of children younger than 12 years old were recruited from primary schools' parental meetings in the Eastern Province of Saudi Arabia from September 2012 to January 2013. The structure of the PAPA instrument was validated using Confirmatory Factor Analysis (CFA) with measurement model fit evaluated using the raw and scaled χ2, Goodness of Fit Index, and Root Mean Square Error of Approximation.

RESULTS

A five-factor model was confirmed with the model showing good fit. Constructs in the model include: Knowledge and Beliefs, Behaviors, Sources of information, Adherence, and Awareness about antibiotics resistance. The instrument was shown to have good internal consistency, and good discriminant and convergent validity.

CONCLUSION

The availability of an instrument able to measure the psychosocial factors underlying antibiotics usage allows the risk factors underlying antibiotic use and overuse to now be investigated.

Acetaminophen (paracetamol) for the common cold in adults

BACKGROUND

Acetaminophen is frequently prescribed for treating patients with the common cold, but there is little evidence as to whether it is effective.

OBJECTIVES

To determine the efficacy and safety of acetaminophen in the treatment of the common cold in adults.

SEARCH METHODS

We searched CENTRAL 2013, Issue 1, Ovid MEDLINE (1950 to January week 5, 2013), EMBASE (1980 to February 2013), CINAHL (1982 to February 2013) and LILACS (1985 to February 2013).

SELECTION CRITERIA

We included randomised controlled trials (RCTs) comparing acetaminophen to placebo or no treatment in adults with the common cold. Studies were included if the trials used acetaminophen as one ingredient of a combination therapy. We excluded studies in which the participants had complications. Primary outcomes included subjective symptom score and duration of common cold symptoms. Secondary outcomes were overall well being, adverse events and financial costs.

DATA COLLECTION AND ANALYSIS

Two review authors independently screened studies for inclusion, assessed risk of bias and extracted data. We performed standard statistical analyses.

MAIN RESULTS

We included four RCTs involving 758 participants. We did not pool data because of heterogeneity in study designs, outcomes and time points. The studies provided sparse information about effects longer than a few hours, as three of four included studies were short trials of only four to six hours. Participants treated with acetaminophen had significant improvements in nasal obstruction in two of the four studies. One study showed that acetaminophen was superior to placebo in decreasing rhinorrhoea severity, but was not superior for treating sneezing and coughing. Acetaminophen did not improve sore throat or malaise in two of the four studies. Results were inconsistent for some symptoms. Two studies showed that headache and achiness improved more in the acetaminophen group than in the placebo group, while one study showed no difference between the acetaminophen and placebo group. None of the included studies reported the duration of common cold symptoms. Minor side effects (including gastrointestinal adverse events, dizziness, dry mouth, somnolence and increased sweating) in the acetaminophen group were reported in two of the four studies. One of them used a combination of pseudoephedrine and acetaminophen.

AUTHORS' CONCLUSIONS

Acetaminophen may help relieve nasal obstruction and rhinorrhoea but does not appear to improve some other cold symptoms (including sore throat, malaise, sneezing and cough). However, two of the four included studies in this review were small and allocation concealment was unclear in all four studies. The data in this review do not provide sufficient evidence to inform practice regarding the use of acetaminophen for the common cold in adults. Further large-scale, well-designed trials are needed to determine whether this intervention is beneficial in the treatment of adults with the common cold.

Use of behavioral economics and social psychology to improve treatment of acute respiratory infections (BEARI): rationale and design of a cluster randomized controlled trial [1RC4AG039115-01]--study protocol and baseline practice and provider characteristics

BACKGROUND

Inappropriate antibiotic prescribing for nonbacterial infections leads to increases in the costs of care, antibiotic resistance among bacteria, and adverse drug events. Acute respiratory infections (ARIs) are the most common reason for inappropriate antibiotic use. Most prior efforts to decrease inappropriate antibiotic prescribing for ARIs (e.g., educational or informational interventions) have relied on the implicit assumption that clinicians inappropriately prescribe antibiotics because they are unaware of guideline recommendations for ARIs. If lack of guideline awareness is not the reason for inappropriate prescribing, educational interventions may have limited impact on prescribing rates. Instead, interventions that apply social psychological and behavioral economic principles may be more effective in deterring inappropriate antibiotic prescribing for ARIs by well-informed clinicians.

METHODS/DESIGN

The Application of Behavioral Economics to Improve the Treatment of Acute Respiratory Infections (BEARI) Trial is a multisite, cluster-randomized controlled trial with practice as the unit of randomization. The primary aim is to test the ability of three interventions based on behavioral economic principles to reduce the rate of inappropriate antibiotic prescribing for ARIs. We randomized practices in a 2 × 2 × 2 factorial design to receive up to three interventions for non-antibiotic-appropriate diagnoses: 1) Accountable Justifications: When prescribing an antibiotic for an ARI, clinicians are prompted to record an explicit justification that appears in the patient electronic health record; 2) Suggested Alternatives: Through computerized clinical decision support, clinicians prescribing an antibiotic for an ARI receive a list of non-antibiotic treatment choices (including prescription options) prior to completing the antibiotic prescription; and 3) Peer Comparison: Each provider's rate of inappropriate antibiotic prescribing relative to top-performing peers is reported back to the provider periodically by email. We enrolled 269 clinicians (practicing attending physicians or advanced practice nurses) in 49 participating clinic sites and collected baseline data. The primary outcome is the antibiotic prescribing rate for office visits with non-antibiotic-appropriate ARI diagnoses. Secondary outcomes will examine antibiotic prescribing more broadly. The 18-month intervention period will be followed by a one year follow-up period to measure persistence of effects after interventions cease.

DISCUSSION

The ongoing BEARI Trial will evaluate the effectiveness of behavioral economic strategies in reducing inappropriate prescribing of antibiotics.

Intranasal ipratropium bromide for the common cold

BACKGROUND

The common cold is one of the most common illnesses in humans and constitutes an economic burden both in terms of productivity and expenditure for treatment. There is no proven cure for the common cold and symptomatic relief is the mainstay of treatment. The use of intranasal ipratropium bromide (IB) has been addressed in several studies and might prove an effective treatment for the common cold.

OBJECTIVES

To determine the effect of IB versus placebo or no treatment on severity of rhinorrhoea and nasal congestion in children and adults with the common cold. Subjective overall improvement was another primary outcome and side effects (for example, dry mucous membranes, epistaxis and systemic anticholinergic effects) were reported as a secondary outcome.

SEARCH METHODS

In this updated review we searched CENTRAL 2013, Issue 3, MEDLINE (1950 to March week 4, 2013), MEDLINE in-process and other non-indexed citations (8 April 2013), EMBASE (1974 to April 2013), AMED (1985 to April 2013), Biosis (1974 to February 2011) and LILACS (1985 to April 2013).

SELECTION CRITERIA

Randomised controlled trials (RCTs) comparing IB to placebo or no treatment in children and adults with the common cold.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data and assessed trial quality. We used a standardised form to extract relevant data and we contacted trial authors for additional information.

MAIN RESULTS

Seven trials with a total of 2144 participants were included. Four studies (1959 participants) addressed subjective change in severity of rhinorrhoea. All studies were consistent in reporting statistically significant changes in favour of IB. Nasal congestion was reported in four studies and was found to have no significant change between the two groups. Two studies found a positive response in the IB group for the global assessment of overall improvement. Side effects were more frequent in the IB group, odds ratio (OR) 2.09 (95% confidence interval (CI) 1.40 to 3.11). Commonly encountered side effects included nasal dryness, blood tinged mucus and epistaxis. The overall risk of bias in the included studies was moderate.

AUTHORS' CONCLUSIONS

For people with the common cold, the existing evidence, which has some limitations, suggests that IB is likely to be effective in ameliorating rhinorrhoea. IB had no effect on nasal congestion and its use was associated with more side effects compared to placebo or no treatment although these appeared to be well tolerated and self limiting. There is a need for larger, high-quality trials to determine the effectiveness of IB in relieving common cold symptoms.

Antibiotics for the common cold and acute purulent rhinitis

BACKGROUND

It has long been believed that antibiotics have no role in the treatment of common colds yet they are often prescribed in the belief that they may prevent secondary bacterial infections.

OBJECTIVES

To determine the efficacy of antibiotics compared with placebo for reducing general and specific nasopharyngeal symptoms of acute upper respiratory tract infections (URTIs) (common colds).To determine if antibiotics have any influence on the outcomes for acute purulent rhinitis and acute clear rhinitis lasting less than 10 days before the intervention.To determine whether there are significant adverse outcomes associated with antibiotic therapy for participants with a clinical diagnosis of acute URTI or acute purulent rhinitis.

SEARCH METHODS

For this 2013 update we searched CENTRAL 2013, Issue 1, MEDLINE (March 2005 to February week 2, 2013), EMBASE (January 2010 to February 2013), CINAHL (2005 to February 2013), LILACS (2005 to February 2013) and Biosis Previews (2005 to February 2013).

SELECTION CRITERIA

Randomised controlled trials (RCTs) comparing any antibiotic therapy against placebo in people with symptoms of acute upper respiratory tract infection for less than seven days, or acute purulent rhinitis less than 10 days in duration.

DATA COLLECTION AND ANALYSIS

Both review authors independently assessed trial quality and extracted data.

MAIN RESULTS

This updated review included 11 studies. Six studies contributed to one or more analyses related to the common cold, with up to 1047 participants. Five studies contributed to one or more analyses relating to purulent rhinitis, with up to 791 participants. One study contributed only to data on adverse events and one met the inclusion criteria but reported only summary statistics without providing any numerical data that could be included in the meta-analyses. Interpretation of the combined data is limited because some studies included only children, or only adults, or only males; a wide range of antibiotics were used and outcomes were measured in different ways. There was a moderate risk of bias because of unreported methods details or because an unknown number of participants were likely to have chest or sinus infections.Participants receiving antibiotics for the common cold did no better in terms of lack of cure or persistence of symptoms than those on placebo (risk ratio (RR) 0.95, 95% confidence interval (CI) 0.59 to 1.51, (random-effects)), based on a pooled analysis of six trials with a total of 1047 participants. The RR of adverse effects in the antibiotic group was 1.8, 95% CI 1.01 to 3.21, (random-effects). Adult participants had a significantly greater risk of adverse effects with antibiotics than with placebo (RR 2.62, 95% CI 1.32 to 5.18) (random-effects) while there was no greater risk in children (RR 0.91, 95% CI 0.51 to 1.63).The pooled RR for persisting acute purulent rhinitis with antibiotics compared to placebo was 0.73 (95% CI 0.47 to 1.13) (random-effects), based on four studies with 723 participants. There was an increase in adverse effects in the studies of antibiotics for acute purulent rhinitis (RR 1.46, 95% CI 1.10 to 1.94).

AUTHORS' CONCLUSIONS

There is no evidence of benefit from antibiotics for the common cold or for persisting acute purulent rhinitis in children or adults. There is evidence that antibiotics cause significant adverse effects in adults when given for the common cold and in all ages when given for acute purulent rhinitis. Routine use of antibiotics for these conditions is not recommended.

Complementary and integrative treatments: upper respiratory infection

The combination of nasal congestion, rhinorrhea, sore throat, cough, and malaise is the symptomatic profile that constitutes an uncomplicated upper respiratory tract infection (URI), also known as the common cold. Because no known cure exists for a URI, numerous products are available, each marketed with the promise of alleviating the associated symptoms and/or shortening the duration of illness. The evidence supporting these claims is variable and is the focus of this article, with an emphasis on complementary and integrative therapies.

Systemic antibiotic use among children and adolescents in Germany: a population-based study

The aim of the study was to comprehensively describe antibiotic use among children and young adolescents in Germany. Outpatient prescriptions of systemic antibiotics to children (<15 years) were analysed using data from four German statutory health insurances for the years 2004 to 2006. Annual prevalence of antibiotic prescriptions was determined using the average number of insured children during the respective year as reference population. Annual antibiotic prescription rates were calculated per 1,000 person years. Both figures were stratified by age (0-4, 5-9 and 10-14 years) and sex. Frequent indications for prescribing were analysed. Annual prevalence of antibiotic prescriptions rose from 35.68 % [95 % confidence intervals (CI), 35.62-35.75] in 2004 to 37.79 % [95 % CI, 37.72-37.86] in 2006. Prescription rates slightly increased by 6.01 % from 668.54 [95 % CI, 667.34-669.72] antibiotic prescriptions per 1,000 person years in 2004 to 708.71 [95 % CI, 707.47-709.95] in 2006. In 2006, prescriptions of broad-spectrum penicillins (25.09 %), second-generation cephalosporins (18.11 %) and narrow-spectrum penicillins (16.45 %) were most frequent. The most common indication for antibiotic prescribing was tonsillitis followed by bronchitis, otitis media, acute upper respiratory infections and scarlet fever.

CONCLUSION

In contrast to other northern European countries, paediatric prescription rates are high in Germany. This and the frequent prescribing of broad spectrum agents for the treatment of mostly viral self-limiting conditions indicate limited adherence to evidence-based practice guidelines in antibiotic prescribing in the German outpatient setting.

Rationale, design and organization of the delayed antibiotic prescription (DAP) trial: a randomized controlled trial of the efficacy and safety of delayed antibiotic prescribing strategies in the non-complicated acute respiratory tract infections in general practice

Background

Respiratory tract infections are an important burden in primary care and it’s known that they are usually self-limited and that antibiotics only alter its course slightly. This together with the alarming increase of bacterial resistance due to increased use of antimicrobials calls for a need to consider strategies to reduce their use. One of these strategies is the delayed prescription of antibiotics.

Methods

Multicentric, parallel, randomised controlled trial comparing four antibiotic prescribing strategies in acute non-complicated respiratory tract infections. We will include acute pharyngitis, rhinosinusitis, acute bronchitis and acute exacerbation of chronic bronchitis or chronic obstructive pulmonary disease (mild to moderate). The therapeutic strategies compared are: immediate antibiotic treatment, no antibiotic treatment, and two delayed antibiotic prescribing (DAP) strategies with structured advice to use a course of antibiotics in case of worsening of symptoms or not improving (prescription given to patient or prescription left at the reception of the primary care centre 3 days after the first medical visit).

Discussion

Delayed antibiotic prescription has been widely used in Anglo-Saxon countries, however, in Southern Europe there has been little research about this topic. The DAP trial wil evaluate two different delayed strategies in Spain for the main respiratory infections in primary care.

Trial registration

This trial is registered with ClinicalTrials.gov, number http://NCT01363531.

Risks and benefits associated with antibiotic use for acute respiratory infections: a cohort study

PURPOSE

Antibiotics are frequently prescribed for acute nonspecific respiratory infections (ARIs), presumably to avoid small risks of progression to serious bacterial illness. However, even low risks of associated adverse drug events could result in many such events at the population level. Our objective was to assess the risks and benefits of antibiotic use in a cohort of patients with ARIs, comparing outcomes of patients who were prescribed antibiotics with outcomes of patients not receiving antibiotics.

METHODS

We used a June 1986 to August 2006 cohort of adult patients with ARI visits from a UK primary care database. Exposure was an antibiotic prescribed with the visit. Primary outcomes were hospitalization within 15 days for (1) severe adverse drug events (hypersensitivity, diarrhea, seizure, arrhythmia, hepatic or renal failure), and (2) community-acquired pneumonia.

RESULTS

The cohort included 1,531,019 visits with an ARI diagnosis; prescriptions for antibiotics were given in 65% of cases. The adjusted risk difference for treated vs untreated patients per 100,000 visits was 1.07 fewer adverse events (95% CI, -4.52 to 2.38; P = .54) and 8.16 fewer pneumonia hospitalizations (95% CI, -13.24 to -3.08; P = .002). The number needed to treat to prevent 1 hospitalization for pneumonia was 12,255.

CONCLUSIONS

Compared with patients with ARI who were not treated with antibiotics, patients who were treated with antibiotics were not at increased risk of severe adverse drug events and had a small decreased risk of pneumonia hospitalization. This small benefit from antibiotics for a common ambulatory diagnosis creates persistent tension; at the societal level, physicians are compelled to reduce antibiotic prescribing, thus minimizing future resistance, whereas at the encounter level, they are compelled to optimize the benefit-risk balance for that patient.

Treatment of common cold patients with the shi-cha capsule: a multicenter, double-blind, randomized, placebo-controlled, dose-escalation trial

This study was designed to determine the therapeutic efficacy and safety of the Shi-cha capsule, a Chinese herbal formula, in the treatment of patients with wind-cold type common cold. In our multi-center, prospective, double-blind, randomized, placebo-controlled, dose-escalation trial, patients with wind-cold type common cold received 0.6 g of Shi-cha capsule plus 0.6 g placebo (group A), 1.2 g of Shi-cha capsule (group B), or 1.2 g placebo (group C), three times daily for 3 days and followed up to 10 days. The primary end point was all symptom duration. The secondary end points were main symptom duration, minor symptom duration, the changes in cumulative symptom score, main symptom score, and minor symptom score 4 days after the treatment, as well as adverse events. A total of 377 patients were recruited and 360 met the inclusive criteria; 120 patients constituted each treatment group. Compared with patients in group C, patients in groups A and B had significant improvement in the all symptom duration, main symptom duration, minor symptom duration, as well as change from baseline of cumulative symptom score, main symptom score, and minor symptom score at day 4. The symptom durations and scores showed slight superiority of group B over group A, although these differences were not statistically significant. There were no differences in adverse events. The Shi-cha capsule is efficacious and safe for the treatment of patients with wind-cold type common cold. Larger trials are required to fully assess the benefits and safety of this treatment for common cold.

Assessment of antibiotic prescribing in Latvian general practitioners

BACKGROUND

Though general antibiotic consumption data is available, information on the actual patterns of prescribing antibiotics locally is difficult to obtain. An easy to use methodology was designed to assess ambulatory management of infections by Latvian general practitioners (GPs).

METHODS

GPs were asked to record data in a patient data collection form for every patient that received antibiotics. Study period - (7 days) one week in November, 2008. Data recorded included the following details: an antibiotic, the prescribed dose, dosing interval, route of administration combined with the demographic factors of the patient and clinical diagnosis based on a pre-defined list.

RESULTS

Two hundred forty eight forms out of the 600 (41%) were returned by post. Antibiotics were prescribed in 6.4% (1711/26803) of outpatient consultations. In total, 1763 antibiotics were prescribed during the study period. Ninety seven percent of the patients received monotherapy and only 47 (2.7%) patients were prescribed two antibiotics. The most commonly prescribed antibiotics were amoxicillin (33.9% of prescribed), amoxicillin/clavulanate (18,7%) and clarithromycin (7.6%). The most commonly treated indications were pharyngitis (29.8%), acute bronchitis (25.3%) and rhinosinusitis (10.2%). Pneumonia was mostly treated with amoxicillin/clavulanate (25,7%), amoxicillin (15.7%) and clarithromycin (19.3%).

CONCLUSIONS

Methodology employed provided useful additional information on ambulatory practice of prescribing antibiotics and could be used in further assessment studies. Educational interventions should be focused on treatment of acute pharyngitis and bronchitis in children and unnecessary use of quinolones in adults for uncomplicated urinary tract infection.

Antibiotics for clinically diagnosed acute rhinosinusitis in adults

BACKGROUND

In primary care settings, the diagnosis of rhinosinusitis is generally based on clinical signs and symptoms. Technical investigations are not routinely performed, nor recommended. Individual trials show a trend in favour of antibiotics, but the balance of benefit versus harm is unclear.

OBJECTIVES

To assess the effect of antibiotics in adults with clinically diagnosed rhinosinusitis in primary care settings.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 2, 2012), MEDLINE (January 1950 to February week 4, 2012) and EMBASE (January 1974 to February 2012).

SELECTION CRITERIA

Randomised controlled trials (RCTs) of antibiotics versus placebo in participants with rhinosinusitis-like signs or symptoms.

DATA COLLECTION AND ANALYSIS

Two authors independently extracted data and assessed the risk of bias. We contacted trial authors for additional information. We collected information on adverse effects from the trials.

MAIN RESULTS

We included 10 trials involving 2450 participants. Overall, the risk of bias in these studies was low. Irrespective of the treatment group, 47% of participants were cured after one week and 71% after 14 days. Antibiotics can shorten the time to cure, but only five more participants per 100 will cure faster at any time point between 7 and 14 days if they receive antibiotics instead of placebo (number needed to treat to benefit (NNTB)) 18 (95% confidence interval (CI) 10 to 115, I(2) statistic 0%, eight trials). Purulent secretion resolves faster with antibiotics (odds ratio (OR) 1.58 (95% CI 1.13 to 2.22)), (NNTB 11, 95% CI 6 to 51, I(2) statistic 0%, three trials). However, 27% of the participants who received antibiotics and 15% of those who received placebo experienced adverse events (OR 2.10, 95% CI 1.60 to 2.77) (number needed to treat to harm (NNTH)) 8 (95% CI 6 to 13, I(2) statistic 13%, seven trials). More participants in the placebo group needed to start antibiotic therapy because of an abnormal course of rhinosinusitis (OR 0.49, 95% CI 0.36 to 0.66), NNTH 20 (95% CI 14 to 35, I(2) statistic 0%, eight trials). Only one disease-related complication (brain abscess) occurred in a patient treated with antibiotics.

AUTHORS' CONCLUSIONS

The potential benefit of antibiotics in the treatment of clinically diagnosed acute rhinosinusitis needs to be seen in the context of a high prevalence of adverse events. Taking into account antibiotic resistance and the very low incidence of serious complications, we conclude that there is no place for antibiotics for the patient with clinically diagnosed, uncomplicated acute rhinosinusitis. This review cannot make recommendations for children, patients with a suppressed immune system and patients with severe disease, as these populations were not included in the available trials.

'The body gets used to them': patients' interpretations of antibiotic resistance and the implications for containment strategies

BACKGROUND

Interventions promoting evidence based antibiotic prescribing and use frequently build on the concept of antibiotic resistance but patients and clinicians may not share the same assumptions about its meaning.

OBJECTIVE

To explore patients' interpretations of 'antibiotic resistance' and to consider the implications for strategies to contain antibiotic resistance.

DESIGN

Multi country qualitative interview study.

PARTICIPANTS

One hundred and twenty-one adult patients from primary care research networks based in nine European countries who had recently consulted a primary care clinician with symptoms of Lower Respiratory Tract Infection (LRTI).

APPROACH

Semi-structured interviews with patients following their consultation and subjected to a five-stage analytic framework approach (familiarization, developing a thematic framework from the interview questions and the themes emerging from the data, indexing, charting, and mapping to search for interpretations in the data), with local network facilitators commenting on preliminary reports.

RESULTS

The dominant theme was antibiotic resistance as a property of a 'resistant human body', where the barrier to antibiotic effectiveness was individual loss of responsiveness. Less commonly, patients correctly conceptualized antibiotic resistance as a property of bacteria. Nevertheless, the over-use of antibiotics was a strong central concept in almost all patients' explanations, whether they viewed resistance as located in either the body or in bacteria.

CONCLUSIONS

Most patients were aware of the link between antibiotic use and antibiotic resistance. The identification of the misinterpretation of antibiotic resistance as a property of the human body rather than bacterial cells could inform clearer clinician-patient discussions and public health interventions through emphasising the transferability of resistance, and the societal contribution individuals can make through more appropriate antibiotic prescribing and use.

Treating children without antibiotics in primary healthcare

The overuse of antibiotics in children is becoming a major public health problem. Although most of the common childhood infections such as diarrhea and upper respiratory tract infections are caused by viruses, large volumes of antibiotics are prescribed for these infections in children in the primary care settings. Excessive use of antibiotics is the fundamental risk factor for the development of antibiotic resistance. It is estimated that 90% of upper respiratory tract infections are self limiting viral illnesses and even bacterial infections like acute otitis media often run a self limiting course. Clinical trials have shown that antibiotic use to treat common upper respiratory tract infections like sore throat, nasopharyngitis and otitis media has no or minimal benefit on the clinical outcome. This report discusses two strategies considered to reduce the use of antibiotic in these conditions: i) No prescription, and ii) Delayed prescription of antibiotics for common upper respiratory tract infections. Moreover, this report calls for a significant modification of the prescribing habits of physicians, and to also extend community awareness on the harms of the misuse and overuse of antibiotics. It is imperative to educate health workers as well as the Community in a coordinated and sustainable manner about the growing public health problem of antibiotic resistance.

Developing and evaluating interventions to reduce inappropriate prescribing by general practitioners of antibiotics for upper respiratory tract infections: a randomised controlled trial to compare paper-based and web-based modelling experiments

BACKGROUND

Much implementation research is focused on full-scale trials with little evidence of preceding modelling work. The Medical Research Council Framework for developing and evaluating complex interventions has argued for more and better theoretical and exploratory work prior to a trial as a means of improving intervention development. Intervention modelling experiments (IMEs) are a way of exploring and refining an intervention before moving to a full-scale trial. They do this by delivering key elements of the intervention in a simulation that approximates clinical practice by, for example, presenting general practitioners (GPs) with a clinical scenario about making a treatment decision.

METHODS

The current proposal will run a full, web-based IME involving 250 GPs that will advance the methodology of IMEs by directly comparing results with an earlier paper-based IME. Moreover, the web-based IME will evaluate an intervention that can be put into a full-scale trial that aims to reduce antibiotic prescribing for upper respiratory tract infections in primary care. The study will also include a trial of email versus postal invitations to participate.

DISCUSSION

More effective behaviour change interventions are needed and this study will develop one such intervention and a system to model and test future interventions. This system will be applicable to any situation in the National Health Service where behaviour needs to be modified, including interventions aimed directly at the public.

Comparative effectiveness of medical interventions in adults versus children

OBJECTIVE

To estimate the comparative effectiveness of medical interventions in adults versus children.

STUDY DESIGN

We identified from the Cochrane Database of Systematic Reviews (Issue 1, 2007) meta-analyses with data on at least 1 adult and 1 pediatric randomized trial with binary primary efficacy outcome. For each meta-analysis, we calculated the summary odds ratio of the adult trials and the pediatric trials, respectively; the relative odds ratio (ROR) of the adult versus pediatric odds ratios per meta-analysis; and the summary ROR across all meta-analyses. ROR <1 means that the experimental intervention is more unfavorable in children than adults.

RESULTS

Across 128 eligible meta-analyses (1051 adult and 343 pediatric trials), the summary ROR did not show a statistically significant difference between adults and children (0.96; 95% confidence intervals, 0.86 to 1.08). However, in all meta-analyses except for 1, the individual ROR's 95% confidence intervals could not exclude a relative difference in efficacy over 20%. In two-thirds, the relative difference in observed point estimates exceeded 50%. Nine statistically significant discrepancies were identified; 4 of them were also clinically important.

CONCLUSIONS

Treatment effects are on average similar in adults and children, but available evidence leaves large uncertainty about their relative efficacy. Clinically important discrepancies may occur.

Health Economics of Antibiotics

Antibiotics have made a significant contribution to improving patient health, but policy makers and health care payers are concerned about the costs of antibiotics in addition to their effectiveness. This paper aims to assess the value of antibiotics by examining incremental cost-utility ratios of antibiotics. Evidence was derived from cost-utility analyses of antibiotics included in the Tufts-New England Center Cost-Effectiveness Analysis Registry through September 2009. The analysis included 85 incremental cost-utility ratios from 23 cost-utility analyses. The findings showed that 38.8% of incremental cost-utility ratios related to dominant antibiotics (i.e., more effective and less costly than the comparator); 45.9% referred to antibiotics that improved effectiveness, but also increased costs; and 15.3% related to dominated antibiotics (i.e., less effective and more costly than the comparator). The median ratio was 748 € per quality-adjusted life year. Using threshold values of 20,000 € per quality-adjusted life year and 50,000 € per quality-adjusted life year, the probability that an antibiotic provides value for money was 64% and 67%, respectively. The current evidence base suggests that the majority of antibiotics provide value for money and that antibiotics can aid decision makers to attain further population health improvements, whilst containing pharmaceutical expenditures.

Trends in publications regarding evidence-practice gaps: a literature review

BACKGROUND

Well-designed trials of strategies to improve adherence to clinical practice guidelines are needed to close persistent evidence-practice gaps. We studied how the number of these trials is changing with time, and to what extent physicians are participating in such trials.

METHODS

This is a literature-based study of trends in evidence-practice gap publications over 10 years and participation of clinicians in intervention trials to narrow evidence-practice gaps. We chose nine evidence-based guidelines and identified relevant publications in the PubMed database from January 1998 to December 2007. We coded these publications by study type (intervention versus non-intervention studies). We further subdivided intervention studies into those for clinicians and those for patients. Data were analyzed to determine if observed trends were statistically significant.

RESULTS

We identified 1,151 publications that discussed evidence-practice gaps in nine topic areas. There were 169 intervention studies that were designed to improve adherence to well-established clinical guidelines, averaging 1.9 studies per year per topic area. Twenty-eight publications (34%; 95% CI: 24% - 45%) reported interventions intended for clinicians or health systems that met Effective Practice and Organization of Care (EPOC) criteria for adequate design. The median consent rate of physicians asked to participate in these well-designed studies was 60% (95% CI, 25% to 69%).

CONCLUSIONS

We evaluated research publications for nine evidence-practice gaps, and identified small numbers of well-designed intervention trials and low rates of physician participation in these trials.

Mechanisms of symptoms of common cold and flu

It is the familiar symptoms of sore throat, runny nose, sneezing, and nasal congestion, muscle aches, chilliness and fever, etc., that define the common cold and flu syndromes as self-diagnosed illnesses. Although there is much information about the molecular biology of the viruses that cause the common cold and flu syndromes, there is relatively little research on the immunological, physiological and pathophysiological mechanisms involved in generating the symptoms. This chapter studies the mechanisms that cause local symptoms associated with local inflammation of the airway (sore throat, sneezing, rhinorrhoea and purulent nasal discharge, nasal congestion, sinus pain, watery eyes and cough), and the mechanisms that cause systemic symptoms associated with release of cytokines from leukocytes (headache, chilliness and fever, psychological effects, malaise and mood changes, loss of appetite, and muscle aches and pains).

Infectious disease and boxing

There are no unique boxing diseases but certain factors contributing to the spread of illnesses apply strongly to the boxer, coach, and the training facility. This article examines the nature of the sport of boxing and its surrounding environment, and the likelihood of spread of infection through airborne, contact, or blood-borne routes of transmission. Evidence from other sports such as running, wrestling, and martial arts is included to help elucidate the pathophysiologic elements that could be identified in boxers.

Clinical Practice Guideline: Hoarseness (Dysphonia)

Objective:

This guideline provides evidence-based recommendations on managing hoarseness (dysphonia), defined as a disorder characterized by altered vocal quality, pitch, loudness, or vocal effort that impairs communication or reduces voice-related quality of life (QOL). Hoarseness affects nearly one-third of the population at some point in their lives. This guideline applies to all age groups evaluated in a setting where hoarseness would be identified or managed. It is intended for all clinicians who are likely to diagnose and manage patients with hoarseness.

Purpose:

The primary purpose of this guideline is to improve diagnostic accuracy for hoarseness (dysphonia), reduce inappropriate antibiotic use, reduce inappropriate steroid use, reduce inappropriate use of anti-reflux medications, reduce inappropriate use of radiographic imaging, and promote appropriate use of laryngoscopy, voice therapy, and surgery. In creating this guideline the American Academy of Otolaryngology—Head and Neck Surgery Foundation selected a panel representing the fields of neurology, speech-language pathology, professional voice teaching, family medicine, pulmonology, geriatric medicine, nursing, internal medicine, otolaryngology–head and neck surgery, pediatrics, and consumers.

Results

The panel made strong recommendations that 1) the clinician should not routinely prescribe antibiotics to treat hoarseness and 2) the clinician should advocate voice therapy for patients diagnosed with hoarseness that reduces voice-related QOL. The panel made recommendations that 1) the clinician should diagnose hoarseness (dysphonia) in a patient with altered voice quality, pitch, loudness, or vocal effort that impairs communication or reduces voice-related QOL; 2) the clinician should assess the patient with hoarseness by history and/or physical examination for factors that modify management, such as one or more of the following: recent surgical procedures involving the neck or affecting the recurrent laryngeal nerve, recent endotracheal intubation, radiation treatment to the neck, a history of tobacco abuse, and occupation as a singer or vocal performer; 3) the clinician should visualize the patient's larynx, or refer the patient to a clinician who can visualize the larynx, when hoarseness fails to resolve by a maximum of three months after onset, or irrespective of duration if a serious underlying cause is suspected; 4) the clinician should not obtain computed tomography or magnetic resonance imaging of the patient with a primary complaint of hoarseness prior to visualizing the larynx; 5) the clinician should not prescribe anti-reflux medications for patients with hoarseness without signs or symptoms of gastroesophageal reflux disease; 6) the clinician should not routinely prescribe oral corticosteroids to treat hoarseness; 7) the clinician should visualize the larynx before prescribing voice therapy and document/communicate the results to the speech-language pathologist; and 8) the clinician should prescribe, or refer the patient to a clinician who can prescribe, botulinum toxin injections for the treatment of hoarseness caused by adductor spasmodic dysphonia. The panel offered as options that 1) the clinician may perform laryngoscopy at any time in a patient with hoarseness, or may refer the patient to a clinician who can visualize the larynx; 2) the clinician may prescribe anti-reflux medication for patients with hoarseness and signs of chronic laryngitis; and 3) the clinician may educate/counsel patients with hoarseness about control/preventive measures.

Disclaimer:

This clinical practice guideline is not intended as a sole source of guidance in managing hoarseness (dysphonia). Rather, it is designed to assist clinicians by providing an evidence-based framework for decision-making strategies. The guideline is not intended to replace clinical judgment or establish a protocol for all individuals with this condition, and may not provide the only appropriate approach to diagnosing and managing this problem.

Effect of using an interactive booklet about childhood respiratory tract infections in primary care consultations on reconsulting and antibiotic prescribing: a cluster randomised controlled trial

OBJECTIVE

To establish whether an interactive booklet on respiratory tract infections in children reduces reconsultation for the same illness episode, reduces antibiotic use, and affects future consulting intentions, while maintaining parental satisfaction with care.

DESIGN

Pragmatic cluster randomised controlled trial.

SETTING

61 general practices in Wales and England.

PARTICIPANTS

558 children (6 months to 14 years) presenting to primary care with an acute respiratory tract infection (7 days or less). Children with suspected pneumonia, asthma or a serious concomitant illness, or needing immediate hospital admission were excluded. Three withdrew and 27 were lost to follow-up, leaving 528 (94.6%) with main outcome data.

INTERVENTIONS

Clinicians in the intervention group were trained in the use of an interactive booklet on respiratory tract infections and asked to use the booklet during consultations with recruited patients (and provide it as a take home resource). Clinicians in the control group conducted their consultations as usual.

MAIN OUTCOME MEASURES

The proportion of children who attended a face-to-face consultation about the same illness during the two week follow-up period. Secondary outcomes included antibiotic prescribing, antibiotic consumption, future consulting intentions, and parental satisfaction, reassurance, and enablement.

RESULTS

Reconsultation occurred in 12.9% of children in the intervention group and 16.2% in the control group (absolute risk reduction 3.3%, 95% confidence interval -2.7% to 9.3%, P=0.29). Using multilevel modelling (at the practice and individual level) to account for clustering, no significant difference in reconsulting was noted (odds ratio 0.75; 0.41 to 1.38). Antibiotics were prescribed at the index consultation to 19.5% of children in the intervention group and 40.8% of children in the control group (absolute risk reduction 21.3%, 95% confidence interval 13.7 to 28.9), P<0.001). A significant difference was still present after adjusting for clustering (odds ratio 0.29; 0.14 to 0.60). There was also a significant difference in the proportion of parents who said they would consult in the future if their child developed a similar illness (odds ratio 0.34; 0.20 to 0.57). Satisfaction, reassurance, and parental enablement scores were not significantly different between the two groups.

CONCLUSIONS

Use of a booklet on respiratory tract infections in children within primary care consultations led to important reductions in antibiotic prescribing and reduced intention to consult without reducing satisfaction with care.

Off-label prescribing to children in the United States outpatient setting

OBJECTIVE

The aim of this study was to determine the frequency of off-label prescribing to children at United States outpatient visits and to determine how drug class, patient age, and physician specialty relate to off-label prescribing.

METHODS

Data from the 2001 through 2004 National Ambulatory Medical Care Surveys (NAMCS) consisted of a sample of 7901 outpatient visits by children aged 0 through 17 years in which prescriptions were given, representative of an estimated 312 million visits. We compared FDA-approved age and indication to the child's age and diagnoses. We used multivariate logistic regression to determine adjusted differences in probabilities of off-label prescribing.

RESULTS

Sixty-two percent of outpatient pediatric visits included off-label prescribing. Approximately 96% of cardiovascular-renal, 86% of pain, 80% of gastrointestinal, and 67% of pulmonary and dermatologic medication prescriptions were off label. Visits by children aged <6 years had a higher probability of off-label prescribing (P < .01), especially visits by children aged <1 year (74% adjusted probability). Visits to specialists also involved a significantly increased probability (68% vs 59% for general pediatricians, P < .01) of off-label prescribing.

CONCLUSIONS

Despite recent studies and labeling changes of pediatric medications, the majority of pediatric outpatient visits involve off-label prescribing across all medication categories. Off-label prescribing is more frequent for younger children and those receiving care from specialist pediatricians. Increased dissemination of pediatric studies and label information may be helpful to guide clinical practice. Further research should be prioritized for the medications most commonly prescribed off label and to determine outcomes, causes, and appropriateness of off-label prescribing to children.

Upper respiratory tract infections (including otitis media)

Upper respiratory tract infections (including otitis media) are the most common illnesses affecting children. Most illnesses are mild and resolve completely without specific treatment, but the frequency of infection and association with fever and constitutional symptoms creates significant distress for the child and the family. By understanding the evidence available from high-quality studies, the clinician can advise the families on appropriate action. The goal of this article is to support clinicians in answering the following questions: (1) What happened to children with these conditions when no additional treatment was provided? (2) Which interventions have been assessed in well-designed studies? (3) Which interventions have been shown to improve outcomes? (4) How large is the overall benefit?

Antibiotic prescribing patterns and hospital admissions with respiratory and urinary tract infections

OBJECTIVE

To explore the relationship between antibiotic prescribing indicators for assessing the prescribing quality of general practitioners (GPs) and populations' health outcome indicators.

DESIGN

Descriptive cross-sectional study.

SETTING

Aljarafe Primary Health Care Area (population 321,034) under the administrative jurisdiction of the Andalusian Public Health Care Service, Spain. In total, 162 GPs, representing 95.29% of the total number of GPs in the study area, were included in the analysis.

METHODS

Antibiotic prescribing indicators based on clinical evidence and recommendations from local resistance patterns were chosen by the consensus group technique. Hospital admissions due to respiratory tract and urinary infections in the three hospitals of the study area were recorded. Multiple regression analysis was carried out to determine the relationship between community prescribing of antibiotics and hospital admissions due to serious complications from respiratory and urinary infections.

RESULTS

The higher prescribing of antibiotics adjusted for patients and working days was associated with a significantly higher number of adjusted hospital admissions due complications arising from respiratory and urinary infections (p < 0.001) (R (2) = 0.142). This relationship was not found for indicators based on the relative prescribing of recommended first-line versus second and third-line antibiotics. There were fewer patients of women GPs admitted to hospitals (p = 0.021).

CONCLUSIONS

Our findings show a statistically significant relationship-at the GPs level-between the quantitative antibiotic prescribing rate and standardized hospital admissions due to complications arising from respiratory and urinary infections of the assisted patients. Strategies should be addressed to reduce unnecessary antibiotic prescribing in primary care.

Public beliefs on antibiotics and respiratory tract infections: an internet-based questionnaire study

BACKGROUND

Patient expectations are among the strongest predictors of clinicians' antibiotic prescribing decisions. Although public knowledge, beliefs, and experiences of antibiotics contribute to these expectations, little is known about these public views.

AIM

To gain insight into public knowledge, beliefs, and experiences of antibiotics and respiratory tract infections.

DESIGN OF STUDY

Cross-sectional, internet-based questionnaire study.

SETTING

Members of the general public aged 16 years and over in the Netherlands.

METHODS

Public knowledge, beliefs, and experiences of antibiotics and respiratory tract infections, as well as predictors of accurate knowledge of antibiotic effectiveness, were measured using 20 questions with sub-items. The questionnaire was given to a Dutch community-based nationwide internet panel of 15 673 individuals. Of these, 1248 eligible responders were invited to participate; 935 responders (75%) completed the questionnaire.

RESULTS

Of the participants, 44.6% accurately identified antibiotics as being effective against bacteria and not viruses. Acute bronchitis was considered to require treatment with antibiotics by nearly 60% of responders. The perceived need for antibiotics for respiratory tract infection-related symptoms ranged from 6.5% for cough with transparent phlegm, to 46.2% for a cough lasting for more than 2 weeks.

CONCLUSION

Public misconceptions on the effectiveness of, and indications for, antibiotics exist. Nearly half of all responders (47.8%) incorrectly identified antibiotics as being effective in treating viral infections. Doctors should be aware that unnecessary prescribing could facilitate misconceptions regarding antibiotics and respiratory tract infections. Expectations of receiving antibiotics were higher for the disease label 'acute bronchitis' than for any of the separate or combined symptoms prominently present in respiratory tract infection. Public beliefs and expectations should be taken into account when developing interventions targeting the public, patients, and physicians to reduce unnecessary prescribing of antibiotics for respiratory tract infections.
