Adherence-adjusted estimates of benefits and harms from treatment with amoxicillin for LRTI: secondary analysis of a 12-country randomised placebo-controlled trial using randomisation-based efficacy estimators

Pragmatic randomised controlled trial of guided self-help versus individual cognitive behavioural therapy with a trauma focus for post-traumatic stress disorder (RAPID)

Background

Guided self-help has been shown to be effective for other mental conditions and, if effective for post-traumatic stress disorder, would offer a time-efficient and accessible treatment option, with the potential to reduce waiting times and costs.

Objective

To determine if trauma-focused guided self-help is non-inferior to individual, face-to-face cognitive-behavioural therapy with a trauma focus for mild to moderate post-traumatic stress disorder to a single traumatic event.

Design

Multicentre pragmatic randomised controlled non-inferiority trial with economic evaluation to determine cost-effectiveness and nested process evaluation to assess fidelity and adherence, dose and factors that influence outcome (including context, acceptability, facilitators and barriers, measured qualitatively). Participants were randomised in a 1 : 1 ratio. The primary analysis was intention to treat using multilevel analysis of covariance.

Setting

Primary and secondary mental health settings across the United Kingdom's National Health Service.

Participants

One hundred and ninety-six adults with a primary diagnosis of mild to moderate post-traumatic stress disorder were randomised with 82% retention at 16 weeks and 71% at 52 weeks. Nineteen participants and ten therapists were interviewed for the process evaluation.

Interventions

Up to 12 face-to-face, manualised, individual cognitive-behavioural therapy with a trauma focus sessions, each lasting 60-90 minutes, or to guided self-help using Spring, an eight-step online guided self-help programme based on cognitive-behavioural therapy with a trauma focus, with up to five face-to-face meetings of up to 3 hours in total and four brief telephone calls or e-mail contacts between sessions.

Main outcome measures

Primary outcome: the Clinician-Administered PTSD Scale for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, at 16 weeks post-randomisation. Secondary outcomes: included severity of post-traumatic stress disorder symptoms at 52 weeks, and functioning, symptoms of depression, symptoms of anxiety, alcohol use and perceived social support at both 16 and 52 weeks post-randomisation. Those assessing outcomes were blinded to group assignment.

Results

Non-inferiority was demonstrated at the primary end point of 16 weeks on the Clinician-Administered PTSD Scale for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition [mean difference 1.01 (one-sided 95% CI -∞ to 3.90, non-inferiority p = 0.012)]. Clinician-Administered PTSD Scale for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, score improvements of over 60% in both groups were maintained at 52 weeks but the non-inferiority results were inconclusive in favour of cognitive-behavioural therapy with a trauma focus at this timepoint [mean difference 3.20 (one-sided 95% confidence interval -∞ to 6.00, non-inferiority p = 0.15)]. Guided self-help using Spring was not shown to be more cost-effective than face-to-face cognitive-behavioural therapy with a trauma focus although there was no significant difference in accruing quality-adjusted life-years, incremental quality-adjusted life-years -0.04 (95% confidence interval -0.10 to 0.01) and guided self-help using Spring was significantly cheaper to deliver [£277 (95% confidence interval £253 to £301) vs. £729 (95% CI £671 to £788)]. Guided self-help using Spring appeared to be acceptable and well tolerated by participants. No important adverse events or side effects were identified.

Limitations

The results are not generalisable to people with post-traumatic stress disorder to more than one traumatic event.

Conclusions

Guided self-help using Spring for mild to moderate post-traumatic stress disorder to a single traumatic event appears to be non-inferior to individual face-to-face cognitive-behavioural therapy with a trauma focus and the results suggest it should be considered a first-line treatment for people with this condition.

Future work

Work is now needed to determine how best to effectively disseminate and implement guided self-help using Spring at scale.

Clinical diagnosis and treatment of common respiratory tract infections in relation to microbiological profiles in rural health facilities in China: implications for antibiotic stewardship

BACKGROUND

This paper tries to describe prevalence and patterns of antibiotics prescription and bacteria detection and sensitivity to antibiotics in rural China and implications for future antibiotic stewardship.

METHODS

The study was implemented in one village clinic and one township health center in each of four rural residential areas in Anhui Province, China. It used mixed-methods comprising non-participative observations, exit-survey and microbiological study. Observations were conducted to record clinical diagnosis and antibiotic prescription. Semi-structured questionnaire survey was used to collect patient's sociodemographic information and symptoms. Sputum and throat swabs were collected for bacterial culture and susceptibility testing.

RESULTS

A total of 1068 (51.0% male vs 49.0% female) patients completed the study with diagnosis of respiratory tract infection (326,30.5%), bronchitis/tracheitis (249,23.3%), pharyngitis (119,11.1%) and others (374, 35.0%). They provided 683 sputum and 385 throat swab specimens. Antibiotics were prescribed for 88% of the RTI patients. Of all the specimens tested, 329 (31%) were isolated with bacteria. The most frequently detected bacteria were K. pneumonia (24% in all specimens), H. influenza (16%), H. parainfluenzae (15%), P. aeruginosa (6%), S.aureus (5%), M. catarrhalis (3%) and S. pneumoniae (2%).

CONCLUSIONS

The study establishes the feasibility of conducting microbiological testing outside Tier 2 and 3 hospitals in rural China. It reveals that prescription of antibiotics, especially broad-spectrum and combined antibiotics, is still very common and there is a clear need for stewardship programs aimed at both reducing the number of prescriptions and promoting single and narrow-spectrum antibiotics.

Information on antibiotics in an Indonesian hospital outpatient setting: What is provided by pharmacy staff and recalled by patients?

Background:

The provision of information by pharmacy staff is a key factor to ensure patients’ understanding and quality use of medications, including antibiotics. However, little is known regarding the transmission of information between pharmacy staff and patients in Indonesia.

Objective:

This study aimed to identify information on antibiotics provided by pharmacy staff and recalled by patients in an Indonesian outpatient setting.

Methods:

The study was conducted in a hospital outpatient clinic in Malang, Indonesia, in 2019. A checklist was used to obtain the data on information provided by pharmacy staff, while interviews were conducted to determine information recalled by patients (only presenting patients were included); a total of 15 information items – i.e. 14 essential and one secondary – were observed. Descriptive analysis was used to summarise data on the checklists (‘given’ versus ‘not given’) as well as responses from the interviews (‘recalled’ versus ‘missed’).

Results:

Eleven pharmacy staff (two pharmacists and nine pharmacy technicians) were involved in providing information for patients obtaining oral antibiotics during the study period. Of 14 essential information items, only about half was given by pharmacy staff, with pharmacists significantly providing on average more information items than pharmacy technicians (7.96 versus 7.67 respectively; p<0.001). The most frequently information items provided (>90%) included “antibiotic identification”, “indication”, administration directions (i.e. “dosage”, “frequency”, “hour of administration”, “administration before/after meal”, “route of administration”), and “duration of use”. A total of 230 patients consented to the study, giving 79.9% response rate. The average number of information items recalled by patients was 7.09 (SD 1.45). Almost all patients could recall information on administration directions [i.e. “route of administration” (97.0%), “frequency” (95.2%), “dosage” (92.6%), “hour of administration” (85.7%), “administration before/after meal” (89.1%)] and “duration of use” (90.9%). Fewer patients were able to recall “antibiotic identification” (76.5%) and “indication” (77.0%).

Conclusions:

Pharmacy staff provided antibiotic information in a limited fashion, while patients showed adequate ability to recall the information given to them. Further study is needed to better understand the effective process of information transmission between pharmacy staff and patients, especially if more information was provided, to better optimise the use of antibiotics in outpatient settings in Indonesia.

Impact of antibiotics for children presenting to general practice with cough on adverse outcomes: secondary analysis from a multicentre prospective cohort study

Background

Clinicians commonly prescribe antibiotics to prevent major adverse outcomes in children presenting in primary care with cough and respiratory symptoms, despite limited meaningful evidence of impact on these outcomes.

Aim

To estimate the effect of children’s antibiotic prescribing on adverse outcomes within 30 days of initial consultation.

Design and setting

Secondary analysis of 8320 children in a multicentre prospective cohort study, aged 3 months to <16 years, presenting in primary care across England with acute cough and other respiratory symptoms.

Method

Baseline clinical characteristics and antibiotic prescribing data were collected, and generalised linear models were used to estimate the effect of antibiotic prescribing on adverse outcomes within 30 days (subsequent hospitalisations and reconsultation for deterioration), controlling for clustering and clinicians’ propensity to prescribe antibiotics.

Results

Sixty-five (0.8%) children were hospitalised and 350 (4%) reconsulted for deterioration. Clinicians prescribed immediate and delayed antibiotics to 2313 (28%) and 771 (9%), respectively. Compared with no antibiotics, there was no clear evidence that antibiotics reduced hospitalisations (immediate antibiotic risk ratio [RR] 0.83, 95% confidence interval [CI] = 0.47 to 1.45; delayed RR 0.70, 95% CI = 0.26 to 1.90, overall P = 0.44). There was evidence that delayed (rather than immediate) antibiotics reduced reconsultations for deterioration (immediate RR 0.82, 95% CI = 0.65 to 1.07; delayed RR 0.55, 95% CI = 0.34 to 0.88, overall P = 0.024).

Conclusion

Most children presenting with acute cough and respiratory symptoms in primary care are not at risk of hospitalisation, and antibiotics may not reduce the risk. If an antibiotic is considered, a delayed antibiotic prescription may be preferable as it is likely to reduce reconsultation for deterioration.

Booklet for Childhood Fever in Out-of-Hours Primary Care: A Cluster-Randomized Controlled Trial

PURPOSE

Fever is the most common reason for a child to be taken to a physician, yet the level of unwarranted antibiotic prescribing remains high. We aimed to determine the effect on antibiotic prescribing of providing an illness-focused interactive booklet on fever in children to out-of-hours primary care clinicians.

METHODS

We conducted a cluster-randomized controlled trial in 20 out-of-hours general practice centers in the Netherlands. Children aged younger than 12 years with fever were included. Family physicians at the 10 intervention sites had access to an illness-focused interactive booklet between November 2015 and June 2016. The primary outcome was antibiotic prescribing during the index consultation. Analysis was performed by fitting 2-level random intercept logistic regression models.

RESULTS

The trial took place among 3,518 family physicians and 25,355 children. The booklet was used in 28.5% of 11,945 consultations in the intervention group. Compared with usual care, access to the booklet did not significantly alter antibiotic prescribing during the index consultation (odds ratio = 0.90; 95% CI, 0.79-1.02; prescription rate, 23.5% vs 25.2%; intracluster correlation coefficient = 0.005). In contrast, use of the booklet significantly reduced antibiotic prescribing (odds ratio = 0.83; 95% CI, 0.74-0.94; prescription rate, 21.9% vs 25.2%; intracluster correlation coefficient = 0.002). Children managed by family physicians with access to the booklet were less likely to receive any drug prescription, and parents in the booklet group showed a reduced intention to consult again for similar illnesses.

CONCLUSIONS

Benefit of an illness-focused interactive booklet in improving outcomes of childhood fever in out-of-hours primary care was largely restricted to the cases in which family physicians actually used the booklet. Insight into reasons for use and nonuse may inform future interventions of this type.

Bronchitis (acute)

INTRODUCTION

Acute bronchitis affects more than 40 in 1000 adults per year in the UK. The causes are usually considered to be infective, but only around half of people have identifiable pathogens. The role of smoking or of environmental tobacco smoke inhalation in predisposing to acute bronchitis is unclear. One third of people may have longer-term symptoms or recurrence.

METHODS AND OUTCOMES

We conducted a systematic review, aiming to answer the following clinical question: What are the effects of treatments for acute bronchitis in people without chronic respiratory disease? We searched: Medline, Embase, The Cochrane Library, and other important databases up to May 2015 (Clinical Evidence overviews are updated periodically; please check our website for the most up-to-date version of this overview).

RESULTS

At this update, searching of electronic databases retrieved 420 studies. After deduplication and removal of conference abstracts, 306 records were screened for inclusion in the overview. Appraisal of titles and abstracts led to the exclusion of 245 studies and the further review of 61 full publications. Of the 61 full articles evaluated, three updated systematic reviews and three RCTs were added at this update. We performed a GRADE evaluation for 12 PICO combinations.

CONCLUSIONS

In this systematic review we categorised the efficacy for six intervention-comparison combinations, based on information about the effectiveness and safety of the following interventions: antibiotics, antihistamines, antitussives, beta2 agonists (inhaled), and expectorants/mucolytics.
