Clinical guidelines recommend non-pharmacological therapies, but the evidence to support this recommendation is sparse. This study aims to evaluate the effect of a 12-week group cognitive-behavioural therapy (CBT) programme for adolescents with ADHD aged 14-18 years, who still have impairing symptoms after treatment with medication. We will study the effect of the treatment on ADHD symptoms and examine moderators and mediators of the effect of the treatment on ADHD. METHODS AND ANALYSIS We conduct a randomised controlled trial of CBT group therapy in adolescents with ADHD recruited from child psychiatric outpatient units in Mid-Norway. 99 adolescents who met inclusion criteria and consented to participation have been randomised to a 12-week group intervention or to a control group receiving treatment as usual. Assessments are made at admission to the clinic, preintervention, postinoyer(s)) 2020. Re-use permitted under CC BY-NC. No commercial re-use. See rights and permissions.

METHODS AND ANALYSIS We will search the following databases (PubMed, Web of Science, EMBASE, Cochrane Library, CINAHL, Clinicaltrials.gov, WHO International Clinical Trials Registry Platform, Google Scholar, Chinese National Knowledge Infrastructure, Chinese Science and Technology Periodicals Database, Chinese BioMedical Database and Wanfang Data) from the date of database inception to January 2019. Only randomised controlled trials will be included. For the data analysis, we will use RevMan V.5.3.5 software to evaluate the risk of bias, and the heterogeneity will be investigated using the Q statistic and P index. Additionally, the Grading of Recommendations Assessment, Development and Evaluation system will be used to assess the quality of evidence. ETHICS AND DISSEMINATION No ethics approval will be required since this is a systematic review of published studies. We aim to report information regarding the effects of peer support on patient anxiety during the perioperative period of coronary angiography or PCI. This systematic review and meta-analysis will be submitted to a peer-reviewed journal for publication. PROSPERO REGISTRATION NUMBER CRD42019123290. © Author(s) (or their employer(s)) 2020.

Experts argue that feedback is critical for performance improvement, but the evidence is limited. The aim of this systematic review was to investigate the effect of face-to-face verbal feedback from a health professional, compared with alternative or no feedback, on the objective workplace task performance of another health professional. DESIGN Systematic review and meta-analysis. METHODS We searched the full holdings of Ovid MEDLINE, CENTRAL, Embase, CINAHL and PsycINFO up to 1 February 2019 and searched references of included studies. Two authors independently undertook study selection, data extraction and quality appraisal. Studies were included if they were randomised controlled trials investigating the effect of feedback, in which health professionals were randomised to individual verbal face-to-face feedback compared with no feedback or alternative feedback and available as fulinterventions, instruction and practice opportunities. CONCLUSIONS Verbal face-to-face feedback in the health professions may result in a moderate to large improvement in workplace task performance, compared with no feedback. However, the quality of evidence was low, primarily due to risk of bias and publication bias. Further research is needed. In particular, we found a lack of high-quality trials that clearly reported key components likely to influence performance.

DESIGN Prospective cohort study. SETTING Patients were recruited from six primary health clinics in Johannesburg. PARTICIPANTS Overall, 1029 newly diagnosed HIV positive adults (≥18 years) were consecutively enrolled by referral from the testing counsellor between April and December 2015 (pre-UTT n=146), July and August 2017 (UTT, n=141) and October 2017 and August 2018 (SDI, n=742). MAIN OUTCOME MEASURES Cox proportional hazards regression was used to assess predictors of 30 days ART initiation. Additionally, predictors of immediate ART initiation were evaluated using Poisson regression. RESULTS Overall, 30 days ART proportions were 71.9% overall, 36.9% pre-UTT (44.3% of those eligible), 65.9% under UTT and 79.9% under the SDI policy. The median days to ART initiation declined from 21 pre-UTT (IQR 15-30) to 8 (IQR 6-16) under UTT and 5 days (IQR 0-8) under the SDI policy. However, only 150 (20.2%) of the SDI cohort-initiated ART immediately after HIV diagnosis. Living in a two-adult home (adjusted HR (aHR) 1.2 vs living alone, 95% CI 1.0 to 1.5) increased the likelihood of 30-day ART. Missing baseline cluster of differentiation four (CD4) data decreased the likelihood of 30 days ART by 40% (aHR 0.6 vs CD4 10 months, 95% CI 0.1 to 0.4). CONCLUSIONS The study results highlight a positive move towards earlier ART initiation during the UTT and SDI periods and emphasise a need to increase same-day ART implementation further. © Author(s) (or their employer(s)) 2020.
