Evaluation of the completeness of intervention reporting in Cochrane surgical systematic reviews using the TIDieR-SR checklist: a cross-sectional study

INTRODUCTION

Complete reporting of systematic reviews of interventions is essential to the interpretation of research findings and the reproducibility of research results. The Template for Intervention Description and Replication (TIDieR) checklist-and the version specific to systematic reviews (TIDieR-SR)-was created to provide authors and researchers an evidence-based guide for reporting trial and systematic review interventions. In this study, we apply TIDieR-SR to Cochrane systematic reviews of surgical interventions.

METHODS

We searched the Cochrane Database for relevant systematic reviews. Two investigators applied inclusion/exclusion criteria to all titles/abstracts and full texts. These same investigators extracted all data in duplicate while masked to the other's data. The primary outcome was adherence to TIDieR-SR items.

RESULTS

Two hundred and thirty-eight systematic reviews were included. Overall, included SRs adhered to a median of 6 (IQR 5-7) out of eight TIDieR-SR items. The item with the lowest adherence was item 7 (share intervention materials, 1/238 (0.4%).

DISCUSSION

Our results are encouraging, but the generalisability of our findings is compromised by the inclusion of only Cochrane systematic reviews. Future reporting of intervention materials is likely to improve the application of effective surgical interventions in the clinical practice.

Strategies to Improve Recruitment to a De-escalation Trial: A Mixed-Methods Study of the OPTIMA Prelim Trial in Early Breast Cancer

AIMS

De-escalation trials are challenging and sometimes may fail due to poor recruitment. The OPTIMA Prelim randomised controlled trial (ISRCTN42400492) randomised patients with early stage breast cancer to chemotherapy versus 'test-directed' chemotherapy, with a possible outcome of no chemotherapy, which could confer less treatment relative to routine practice. Despite encountering challenges, OPTIMA Prelim reached its recruitment target ahead of schedule. This study reports the root causes of recruitment challenges and the strategies used to successfully overcome them.

MATERIALS AND METHODS

A mixed-methods recruitment intervention (QuinteT Recruitment Intervention) was used to investigate the recruitment difficulties and feedback findings to inform interventions and optimise ongoing recruitment. Quantitative site-level recruitment data, audio-recorded recruitment appointments (n = 46), qualitative interviews (n = 22) with trialists/recruiting staff (oncologists/nurses) and patient-facing documentation were analysed using descriptive, thematic and conversation analyses. Findings were triangulated to inform a 'plan of action' to optimise recruitment.

RESULTS

Despite best intentions, oncologists' routine practices complicated recruitment. Discomfort about deviating from the usual practice of recommending chemotherapy according to tumour clinicopathological features meant that not all eligible patients were approached. Audio-recorded recruitment appointments revealed how routine practices undermined recruitment. A tendency to justify chemotherapy provision before presenting the randomised controlled trial and subtly indicating that chemotherapy would be more/less beneficial undermined equipoise and made it difficult for patients to engage with OPTIMA Prelim. To tackle these challenges, individual and group recruiter feedback focussed on communication issues and vignettes of eligible patients were discussed to address discomforts around approaching patients. 'Tips' documents concerning structuring discussions and conveying equipoise were disseminated across sites, together with revisions to the Patient Information Sheet.

CONCLUSIONS

This is the first study illuminating the tension between oncologists' routine practices and recruitment to de-escalation trials. Although time and resources are required, these challenges can be addressed through specific feedback and training as the trial is underway.

Challenging traditional research: A synopsis of the National Research Collaborative Meeting (NRCM) in 2017

Introduction

The National Research Collaborative Meeting (NRCM) 2017 was jointly hosted between the West Midlands Research Collaborative (WMRC) and Student Audit and Research in Surgery (STARSurg) on 30th November 2017 in Birmingham. The NRCM 2017 theme was ‘Challenging Traditional Research’.

Methods

Narrative review, outlining key challenges and recommendations for trainee collaborative research groups across medical and surgical disciplines based on the core themes from the NRCM 2017 meeting.

Results

Core themes of: (1) surgical oncology trials; (2) placebo-controlled surgical trials; (3) research funding; (4) medical student involvement in research; (5) emergency care; (6) patient and public involvement. Recommendations were made for planning future collaborative studies, based on these topic areas.

Conclusions

The collaborative research model has demonstrated longevity and effectiveness in delivering high-quality, practice-changing research both within the NHS and internationally. Learning between groups and highlighting areas for interdisciplinary collaboration will drive a meaningful, patient-centred agenda for the future.
