Background Point of care testing for C-reactive protein (CRP) has shown promise as a measure to reduce unnecessary antibiotic prescribing in respiratory tract infections (RTI), but its use in primary care is still controversial. We aimed to evaluate the effect of CRP testing on the prescription of antibiotics, referral for radiography, and the outcome of patients in general practice with acute cough/RTI. Methods An open-cluster randomized clinical trial was conducted, with CRP testing performed in the intervention group. Antibiotic prescribing and referral for radiography were the main outcome measures. Results A total of 179 patients were included: 101 in the intervention group and 78 in the control group. The two groups were similar in clinical characteristics. In the intervention group, the antibiotic prescribing rate was 37.6%, which was significantly lower than that in the control group (58.9%) (P = 0.006). Referral for chest X-ray was also significantly lower in the intervention group (55.4%) than in the control group (75.6%) (P = 0.004). The recovery rate, as recorded by the GPs, was 92.9% and 93.6% in the intervention and control groups, respectively. Conclusion The study showed that CRP testing in patients with acute cough/RTI may reduce antibiotic prescribing and referral for radiography, probably without compromising recovery.

BACKGROUND: High-volume prescribing of antibiotics in primary care is a major driver of antibiotic resistance. Education of physicians and patients can lower prescribing levels, but it frequently relies on highly trained staff. We assessed whether internet-based training methods could alter prescribing practices in multiple health-care systems. METHODS: After a baseline audit in October to December, 2010, primary-care practices in six European countries were cluster randomised to usual care, training in the use of a C-reactive protein (CRP) test at point of care, in enhanced communication skills, or in both CRP and enhanced communication. Patients were recruited from February to May, 2011. This trial is registered, number ISRCTN99871214. RESULTS: The baseline audit, done in 259 practices, provided data for 6771 patients with lower-respiratory-tract infections (3742 [55·3%]) and upper-respiratory-tract infections (1416 [20·9%]), of whom 5355 (79·1%) were prescribed antibiotics. After randomisation, 246 practices were included and 4264 patients were recruited. The antibiotic prescribing rate was lower with CRP training than without (33% vs 48%, adjusted risk ratio 0·54, 95% CI 0·42-0·69) and with enhanced-communication training than without (36% vs 45%, 0·69, 0·54-0·87). The combined intervention was associated with the greatest reduction in prescribing rate (CRP risk ratio 0·53, 95% CI 0·36-0·74, p<0·0001; enhanced communication 0·68, 0·50-0·89, p=0·003; combined 0·38, 0·25-0·55, p<0·0001). INTERPRETATION: Internet training achieved important reductions in antibiotic prescribing for respiratory-tract infections across language and cultural boundaries.

PURPOSE: The purpose of the study was to assess the long-term effect of family physicians' use of C-reactive protein (CRP) point-of-care testing and/or physician training in enhanced communication skills on office visit rates and antibiotic prescriptions for patients with respiratory tract infections. METHODS: We conducted a 3.5-year follow-up of a pragmatic, factorial, cluster-randomized controlled trial; 379 patients (20 family practices in the Netherlands) who visited their family physician for acute cough were enrolled in the trial and had follow-up data available (88% of original trial cohort). Main outcome measures were the average number of episodes of respiratory tract infections for which patients visited their family physician per patient per year (PPPY), and the percentage of the episodes for which patients were treated with antibiotics during follow-up. RESULTS: The mean number of episodes of respiratory tract infections during follow-up was 0.40 PPPY in the CRP test group and 0.56 PPPY in the no CRP test group (P = .12). In the communication skills training group, there was a mean of 0.36 PPPY episodes of respiratory tract infections, and in the no training group the mean was 0.57 PPPY (P = .09). During follow-up 30.7% of all episodes of respiratory tract infection were treated with antibiotics in the CRP test group compared with 35.7% in the no test group (P = .36). Family physicians trained in communication skills treated 26.3% of all episodes of respiratory tract infection with antibiotics compared with 39.1% treated by family physicians without training in communication skills (P = .02) CONCLUSIONS: Family physicians' use of CRP point-of-care testing and/or training in enhanced communication skills did not significantly affect office visit rates related to respiratory tract infections. Patients who saw a family physician trained in enhanced communication skills were prescribed significantly fewer antibiotics during episodes of respiratory tract infection in the subsequent 3.5 years.

OBJECTIVE: To assess the impact of four patient information leaflets on patients' behavior in primary care. DESIGN: Cluster randomized multicenter controlled trial between November 2009 and January 2011. PARTICIPANTS: French adults and children consulting a participating primary care physician and diagnosed with gastroenteritis or tonsillitis. Patients were randomized to receive patient information leaflets or not, according to the cluster randomization of their primary care physician. INTERVENTION: Adult patients or adults accompanying a child diagnosed with gastroenteritis or tonsillitis were informed of the study. Physicians in the intervention group gave patients an information leaflet about their condition. Two weeks after the consultation patients (or their accompanying adult) answered a telephone questionnaire on their behavior and knowledge about the condition. MAIN MEASURES: The main and secondary outcomes, mean behavior and knowledge scores respectively, were calculated from the replies to this questionnaire. RESULTS: Twenty-four physicians included 400 patients. Twelve patients were lost to follow-up (3 %). In the group that received the patient information leaflet, patient behavior was closer to that recommended by the guidelines than in the control group (mean behavior score 4.9 versus 4.2, p < 0.01). Knowledge was better for adults receiving the leaflet than in the control group (mean knowledge score 4.2 versus 3.6, p < 0.01). There were fewer visits for the same symptoms by household members of patients given leaflets (23.4 % vs. 56.2 %, p < 0.01). CONCLUSION: Patient information leaflets given by the physician during the consultation significantly modify the patient's behavior and knowledge of the disease, compared with patients not receiving the leaflets, for the conditions studied.

The appropriate prescribing of antibiotics is a challenge in primary care12. We performed an interventional trial to determine if providing an information leaflet on antibiotics with a delayed antibiotic prescription influenced the patient's decision to use the antibiotic for a respiratory tract infection (RTI). The control group (n = 69) where given a delayed prescription and the intervention group (n = 46) were given an information leaflet on antibiotics with the delayed prescription. In the control group, 72% (n = 50) of patients indicated they subsequently used the antibiotic, and in the intervention group, 43%(n = 20) indicated they used the antibiotic, this difference was statistically significant (p = 0.0018.) The key conclusion of this study is that delayed prescriptions should be issued with an appropriate information sheet.

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

OBJECTIVE: To evaluate the effectiveness and costs of a multifaceted flexible educational programme aimed at reducing antibiotic dispensing at the practice level in primary care. DESIGN: Randomised controlled trial with general practices as the unit of randomisation and analysis. Clinicians and researchers were blinded to group allocation until after randomisation. SETTING: 68 general practices with about 480,000 patients in Wales, United Kingdom. PARTICIPANTS: 34 practices were randomised to receive the educational programme and 34 practices to be controls. 139 clinicians from the intervention practices and 124 from control practices had agreed to participate before randomisation. Practice level data covering all the clinicians in the 68 practices were analysed. INTERVENTIONS: Intervention practices followed the Stemming the Tide of Antibiotic Resistance (STAR) educational programme, which included a practice based seminar reflecting on the practices' own dispensing and resistance data, online educational elements, and practising consulting skills in routine care. Control practices provided usual care. MAIN OUTCOME MEASURES: Total numbers of oral antibiotic items dispensed for all causes per 1000 practice patients in the year after the intervention, adjusted for the previous year's dispensing. Secondary outcomes included reconsultations, admissions to hospital for selected causes, and costs. RESULTS: The rate of oral antibiotic dispensing (items per 1000 registered patients) decreased by 14.1 in the intervention group but increased by 12.1 in the control group, a net difference of 26.1. After adjustment for baseline dispensing rate, this amounted to a 4.2% (95% confidence interval 0.6% to 7.7%) reduction in total oral antibiotic dispensing for the year in the intervention group relative to the control group (P=0.02). Reductions were found for all classes of antibiotics other than penicillinase-resistant penicillins but were largest and significant individually for phenoxymethylpenicillins (penicillin V) (7.3%, 0.4% to 13.7%) and macrolides (7.7%, 1.1% to 13.8%). There were no significant differences between intervention and control practices in the number of admissions to hospital or in reconsultations for a respiratory tract infection within seven days of an index consultation. The mean cost of the programme was £2923 (€3491, $4572) per practice (SD £1187). There was a 5.5% reduction in the cost of dispensed antibiotics in the intervention group compared with the control group (-0.4% to 11.4%), equivalent to a reduction of about £830 a year for an average intervention practice. CONCLUSION: The STAR educational programme led to reductions in all cause oral antibiotic dispensing over the subsequent year with no significant change in admissions to hospital, reconsultations, or costs. Trial registration ISRCT No 63355948.

This before-after study aimed to evaluate the effect of two interventions on lowering the prescription of antibiotics in lower respiratory tract infections (LRTI) in Spain. General practitioners (GPs) registered all cases with LRTIs over 3-week periods before and after an intervention, in 2008 and 2009. Two types of intervention were considered: full-intervention group (FIG), consisting of discussion sessions of the results of the first registry, courses for GPs, guidelines, patient information leaflets, workshops on rapid tests and use of the C-reactive protein (CRP) test; GPs in the partial-intervention group (PIG) underwent all of the above interventions except for the workshop on rapid tests, and they did not have access to CRP. A multilevel logistic regression analysis was performed considering the prescription of an antibiotic as the dependent variable. 210 physicians were assigned to FIG and 70 to PIG. In 2009, 58 new physicians were included as a control group. 5,385 LRTIs were registered. Compared with the control group, the OR of antibiotic prescription after the intervention in the PIG was 0.42 (95% CI: 0.22-0.82) and 0.22 (95% CI: 0.12-0.38) in the FIG. Intervention led to a reduction in the prescription of antibiotics, mainly when CRP testing was available.

<b>BACKGROUND: </b>Few interventions have proven effective in reducing the overuse of antibiotics for acute respiratory infections. We evaluated the effect of DECISION+2, a shared decision-making training program, on the percentage of patients who decided to take antibiotics after consultation with a physician or resident.<b>METHODS: </b>We performed a randomized trial, clustered at the level of family practice teaching unit, with 2 study arms: DECISION+2 and control. The DECISION+2 training program included a 2-hour online tutorial followed by a 2-hour interactive seminar about shared decision-making. The primary outcome was the proportion of patients who decided to use antibiotics immediately after consultation. We also recorded patients' perception that shared decision-making had occurred. Two weeks after the initial consultation, we assessed patients' adherence to the decision, repeat consultation, decisional regret and quality of life.<b>RESULTS: </b>We compared outcomes among 181 patients who consulted 77 physicians in 5 family practice teaching units in the DECISION+2 group, and 178 patients who consulted 72 physicians in 4 family practice teaching units in the control group. The percentage of patients who decided to use antibiotics after consultation was 52.2% in the control group and 27.2% in the DECISION+2 group (absolute difference 25.0%, adjusted relative risk 0.48, 95% confidence interval 0.34-0.68). DECISION+2 was associated with patients taking a more active role in decision-making (Z = 3.9, p &lt; 0.001). Patient outcomes 2 weeks after consultation were similar in both groups.<b>INTERPRETATION: </b>The shared decision-making program DECISION+2 enhanced patient participation in decision-making and led to fewer patients deciding to use antibiotics for acute respiratory infections. This reduction did not have a negative effect on patient outcomes 2 weeks after consultation. ClinicalTrials.gov trial register no. NCT01116076.

BACKGROUND AND OBJECTIVE: Use of antibiotics in outpatients with community-acquired pneumonia (CAP) is empirical, which may lead to overuse and selection pressure for resistance. Procalcitonin (PCT) levels may predict the severity of CAP and may be used to guide antibiotic use in hospitalized patients. This study evaluated the value of PCT measurements for guiding antibiotic use in low-risk outpatients with CAP. METHODS: This was a randomized intervention trial conducted between February 2005 and December 2008 that included 172 consecutive patients with suspected CAP, of whom 156 completed the study. The control group received antibiotics according to current guidelines. In the PCT group, antibiotic treatment was based on PCT levels as follows: <0.1 µg/L, strongly discouraged; ≤0.25 µg/L, discouraged; >0.25 µg/L, encouraged. The primary end-points were total antibiotic use and duration of antibiotic treatment; laboratory and clinical outcomes were measured. RESULTS: Prescription of antibiotics on admission (84.4% vs 97.5%; P = 0.004), total antibiotic exposure (relative risk 0.55, 95% CI: 0.51-0.60; P = 0.003) and duration of antibiotic treatment (median 5 days vs 7 days; P < 0.001) were reduced in the PCT guidance group, compared with patients treated according to current guidelines. At 4-week follow up, all patients had survived and laboratory and clinical outcomes were similar in the two groups. CONCLUSIONS: Under PCT guidance, antibiotic use was reduced and duration of antibiotic treatment was shortened in low-risk outpatients with CAP, without apparent harm.
