Quality of reporting inflammatory bowel disease randomised controlled trials: a systematic review.

OBJECTIVE: Our objective was to perform a systemic evaluation of the risk of bias in randomised controlled trial (RCT) reports published on inflammatory bowel disease (IBD). DESIGN: We assessed the risk of bias using the Cochrane tool, as indicators of poor methodology or subsequently poor reporting. We systematically selected, with dual independent judgements, all studies published on IBD with no time limits and assessed the methodological quality of included studies again using independent dual ratings. RESULTS: 563 full texts were included after selection and review. No abstract publications were free of any source of bias. Full-text publications still fared badly, as only 103 full-text papers exhibited a low risk of bias in all reporting domains when excluding blinding. RCTs published in journals with higher impact factor (IF) were associated with an overall reduced rate of being at high risk. However, only 6% of full RCT publications in journals with an IF greater than 10, published in the past 5 years, were free of bias.The trend over time is towards improved reporting in all areas. Trials published by larger author teams, in full-text form and by industry and public sponsorship were positively correlated with a lower risk of bias. Only allocation concealment showed a statistically significant improvement with time (p=0.037). CONCLUSION: These findings are consistent with those of other specialties in the literature. While this unclear risk of bias may represent poor reporting of methods instead of poor methodological quality, it leaves readers and future secondary researchers with significant questions regarding such key issues.

Pitfalls preventing bone union with EXOGEN Low-Intensity Pulsed Ultrasound.

OBJECTIVES: To evaluate the efficacy of EXOGEN in achieving union and common pitfalls in its use within the Manchester Foundation Trust (MFT) and Salford Royal Foundation Trust (SRFT). METHOD: Patients receiving EXOGEN therapy between 01/01/2017 and 31/12/2019 at hospitals within MFT and SRFT were identified using EXOGEN logbooks and hospital IT systems. An equal number of patients were included from both sites. Data were retrospectively collected from clinical documents detailing clinical presentation comorbidities, and radiographic images, determining the radiological union post EXOGEN therapy. In addition, local practices were observed and compared to EXOGEN's standardized guidance for clinicians. RESULTS: Fifty-eight patients were included in the primary review, with 9 subsequently excluded based on insufficient clinical data. 47% of patients achieved radiological union following completion of EXOGEN therapy. Outcomes of the 23 patients with persistent non-union were as follows - 18 were referred for revision surgery, 5 were prescribed further EXOGEN therapy, 2 refused or were unfit for further intervention, and 1 did not have a plan documented. No significant baseline differences were present in both outcome groups. However, at MFT and SRFT, rates of union with EXOGEN are below that previously published in the literature. CONCLUSION: EXOGEN has proven successful in facilitating union in established cases of non-union without the risk and cost associated with revision surgery. Centre outcome differences may be explained by failure to educate clinicians and patients on the correct use of the EXOGEN device, failure to standardize follow-up or monitor compliance, and must be addressed to improve current services.

The what, why and when of wide awake local anaesthesia no tourniquet surgery.

Wide awake local anaesthesia no tourniquet, also known as WALANT, is the practice of performing surgery under local anaesthetic in the absence of a tourniquet. This technique uses the vasoconstrictive effects of adrenaline and the local anaesthetic effects of lignocaine to establish a Bier block with haemostatic control. Permitting active patient participation intraoperatively, wide awake local anaesthesia no tourniquet surgery improves patient compliance with rehabilitation and yields higher patient satisfaction. With reduced cost and equipment requirements, this method improves accessibility for patients and productivity for healthcare institutions. This is of particular benefit within the current COVID-19 climate, as wide awake local anaesthesia no tourniquet technique provides a means of overcoming restrictions to theatre access and anaesthetic support. This review delves into the current uses of wide awake local anaesthesia no tourniquet surgery, outlining the initial conception of the practice by Canadian surgeons. The advantages and disadvantages are considered, and potential future applications of this technique are discussed.
