Barriers to uptake of the hip fracture core outcome set: An international survey of 80 hip fracture trialists

Assessing the Uptake of the Lung Cancer Core Outcome Set: A Cross-Sectional Analysis

Introduction

A core outcome set (COS) helps standardize outcome measurements across clinical trials. Although lung cancer is the leading cause of cancer-related deaths, research exploring COS implementation across lung cancer trials remains limited. We aim to analyze the uptake of the lung cancer COS and identify potential gaps in COS adherence.

Methods

On June 26, 2023, we conducted a cross-sectional analysis of clinical trials that evaluated lung cancer interventions. Our sample consisted of studies registered on ClinicalTrials.gov and the WHO International Clinical Trials Registry Platform between September 2011 and June 2023. In a masked and duplicate fashion, investigators extracted data regarding trial characteristics and COS adoption. An interrupted time series analysis was conducted to evaluate the adherence of lung cancer COS before and after its publication.

Results

Of the 626 observed trials, we found no overall significant difference in lung cancer COS uptake pre- and post-publication (0.01%, 95% confidence interval: -0.16% to 0.19%, p=0.85). The most frequently measured outcomes were "overall survival" (91.69%%) and "treatment-related mortalities" (54.69%). Health-related quality of life questionnaires were typically used to evaluate outcomes in the "Degree of health" domain (49.20%). Outcomes related to "time from diagnosis to treatment" (0%), "place of death" (0.16%), and "duration of time spent in the hospital at the end of life" (1.60%) were rarely measured.

Conclusions

Despite the advantages of COS implementation, adherence across lung cancer clinical trials remains alarmingly low-which could compromise data reliability and patient care. Our findings showcase these inconsistencies and emphasize the need for proactive approaches to improve uptake.

Development of a Core Outcome Set for Studies Assessing Interventions for Diabetes-Related Foot Ulceration

OBJECTIVE

Diabetes affects 537 million people globally, with 34% expected to develop foot ulceration in their lifetime. Diabetes-related foot ulceration causes strain on health care systems worldwide, necessitating provision of high-quality evidence to guide their management. Given heterogeneity of reported outcomes, a core outcome set (COS) was developed to standardize outcome measures in studies assessing treatments for diabetes-related foot ulceration.

RESEARCH DESIGN AND METHODS

The COS was developed using Core Outcome Measures in Effectiveness Trials (COMET) methodology. A systematic review and patient interviews generated a long list of outcomes that were rated by patients and experts using a nine-point Likert scale (from 1 [not important] to 9 [critical]) in the first round of the Delphi survey. Based on predefined criteria, outcomes without consensus were reprioritized in a second Delphi round. Critical outcomes and those without consensus after two Delphi rounds were discussed in the consensus meeting where the COS was ratified.

RESULTS

The systematic review and patient interviews generated 103 candidate outcomes. The two consecutive Delphi rounds were completed by 336 and 176 respondents, resulting in an overall second round response rate of 52%. Of 37 outcomes discussed in the consensus meeting (22 critical and 15 without consensus after the second round), 8 formed the COS: wound healing, time to healing, new/recurrent ulceration, infection, major amputation, minor amputation, health-related quality of life, and mortality.

CONCLUSIONS

The proposed COS for studies assessing treatments for diabetes-related foot ulceration was developed using COMET methodology. Its adoption by the research community will facilitate assessment of comparative effectiveness of current and evolving interventions.

Factors associated with reporting of the Prevention of Falls Network Europe (ProFaNE) core outcome set domains in randomized trials on falls in older people: a citation analysis and correlational study

Background

Core outcome sets are advocated as a means to standardize outcome reporting across randomized controlled trials (RCTs) and reduce selective outcome reporting. In 2005, the Prevention of Falls Network Europe (ProFaNE) published a core outcome set identifying five domains that should be measured and reported, at a minimum, in RCTs or meta-analysis on falls in older people. As reporting of all five domains of the ProFaNE core outcome set has been minimal, we set out to investigate factors associated with reporting of the ProFaNE core outcome set domains in a purposeful sample of RCTs on falls in older people.

Methods

We conducted a systematic citation analysis to identify all reports of RCTs focused on falls in older people that cited the ProFaNE core outcome set between October 2005 and July 2021. We abstracted author-level, study-level, and manuscript-level data and whether each domain of the ProFaNE core outcome set was reported. We used penalized LASSO regression to identify factors associated with the mean percentage of ProFaNE core outcome set domains reported.

Results

We identified 85 eligible reports of RCTs. Articles were published between 2007 and 2021, described 75 unique RCTs, and were authored by 76 unique corresponding authors. The percentage of ProFaNE core outcome set domains reported ranged from 0 to 100%, with a median of 40% and mean (standard deviation, SD) of 52.2% (25.1). RCTs funded by a non-industry source reported a higher mean percentage of domains than RCTs without a non-industry funding source (estimated mean difference = 17.5%; 95% confidence interval (CI) 1.8–33.2). RCTs examining exercise (15.4%; 95% CI 1.9–28.9) or multi-component/factorial (17.4%; 95% CI 4.7–30.1) interventions each reported a higher mean percentage of domains than RCTs examining other intervention types.

Conclusions

We found that RCTs funded by at least one non-industry source, examining exercise or multi-component/factorial interventions, reported the highest percentages of ProFaNE core outcome set domains. Findings may help inform strategies to increase the impact of the ProFaNE core outcome set. Ultimately, this may lead to enhanced knowledge of the effectiveness and safety of interventions to prevent and/or manage falls in older people.

Short- and long-term prognostic factors associated with functional recovery in elderly patients with hip fracture: A systematic review

This systematic review aimed to identify short- and long-term associated factors to functional recovery of elderly hip fracture patients after discharge. We identified 43 studies reporting 74 associated factors to functional recovery; most of them were biological, sociodemographic, or inherent factors to patients' baseline characteristics, including their pre-facture functional capacity.

PURPOSE

This systematic review aimed to identify short- and long-term associated factors to functional recovery of elderly hip fracture patients after hospital discharge. We assessed the use of the hip fracture core-set and key-performance indicators for secondary fracture reduction.

METHODS

A search was performed in seven electronic databases. Observational studies reporting predictors after usual care of elderly patients with hip fracture diagnoses receiving surgical or conservative treatment were included. Primary outcomes considered were part of the domains corresponding to functional capacity.

RESULTS

Of 3873 references identified, and after the screening and selection process, 43 studies were included. Sixty-one functional measures were identified for ten functional outcomes, including BADLs, IADLs, ambulation, and mobility. Biological characteristics such as age, sex, comorbidities, cognitive status, nutritional state, and biochemical parameters are significantly associated. Determinants such as contact and size of social network and those related to institutional care quality are relevant for functional recovery at six and 12 months. Age, pre-fracture function, cognitive status, and complications continue to be associated five years after discharge. We found 74 associated factors to functional recovery of elderly hip fracture patients. Ten of the studies reported rehabilitation programs as suggested in KPI 9; none used the complete hip fracture core-set.

CONCLUSION

Most of the associated factors for functional recovery of elderly hip fracture were biological, sociodemographic, or inherent factors to patients' baseline characteristics, including their pre-facture functional capacity. For the core-set and KPI's, we found an insufficient use and report. This study reports 61 different instruments to measure functional capacity.

A survey of knowledge, perceptions and use of core outcome sets among clinical trialists

Background

Core outcome sets (COS) are standardised sets of outcomes, which represent the minimum outcomes that should be measured and reported in clinical trials. COS can enhance comparability across health trials by reducing heterogeneity of outcome measurement and reporting and potentially minimising selective outcome reporting. Examining what researchers involved in trials know and think about COS is essential to increase awareness and promote COS uptake. The aim of this study is therefore to examine clinical trialists’ knowledge, perceptions and experiences of COS.

Methods

An online survey design was used. Participants were clinical trialists, operationalised for the current study as researchers named as the contact person on a trial registered on the International Standard Randomised Controlled Trial Number (ISRCTN) Trial repository between 1 January 2019 and 21 July 2020. Survey items assessed clinical trialists’ familiarity with and understanding of COS, along with experiences of COS use and development.

Results

Of 1913 clinical trialists contacted to participate, 62 (3%) completed the survey. Forty (65%) participants were familiar with COS and, of those familiar with COS, 21 (55%) had been involved in a trial that used a COS. Of clinical trialists who used COS in a trial(s), less than half (n = 9, 41%) reported that all COS outcomes were used. The main barriers to using COS are poor knowledge about COS (n = 43, 69%) and difficulties identifying relevant COS (n = 42, 68%). Clinical trialists also reported perceptions of COS as restrictive and often containing too many outcomes. The main enablers to using COS are clear understanding (n = 51, 82%) and perceived importance of COS (n = 44, 71%).

Conclusions

Enhancing clinical trialists’ use of all COS outcomes is needed to reduce outcome heterogeneity and enhance comparability across trial findings. Enhancing awareness of COS importance among researchers and funders is needed to ensure that COS are developed and used by clinical trialists. Education and training may further promote awareness and understanding of COS.

Core Outcome Set Use in Poststroke Aphasia Treatment Research: Examining Barriers and Facilitators to Implementation Using the Theoretical Domains Framework

Purpose A core outcome set (COS; an agreed minimum set of outcomes) was developed to address the heterogeneous measurement of outcomes in poststroke aphasia treatment research. Successful implementation of a COS requires change in individual and collective research behavior. We used the Theoretical Domains Framework (TDF) to understand the factors influencing researchers' use and nonuse of the Research Outcome Measurement in Aphasia (ROMA) COS. Method Aphasia trialists and highly published treatment researchers were identified from the Cochrane review of speech and language therapy for aphasia following stroke and through database searches. Participants completed a theory-informed online survey that explored factors influencing COS use. Data were analyzed using descriptive statistics and qualitative content analysis. Results Sixty-four aphasia researchers from 13 countries participated. Most participants (81%) were aware of the ROMA COS, and participants identified more facilitators than barriers to its use. The TDF domain with the highest agreement (i.e., facilitator) was "knowledge" (84% agree/strongly agree). Participants had knowledge of the measures included in the ROMA COS, their associated benefits, and the existing recommendations. The TDF domains with the least agreement (i.e., barriers) were "reinforcement" (34% agree/strongly agree); "social influences" (41% agree/strongly agree); "memory, attention, and decision processes" (45% agree/strongly agree); and "behavioral regulation" (49% agree/strongly agree). Hence, participants identified a lack of external incentives, collegial encouragement, and monitoring systems as barriers to using the ROMA COS. The suitability and availability of individual measurement instruments, as well as burden associated with collecting the COS, were also identified as reasons for nonuse. Conclusions Overall, participants were aware of the benefits of using the ROMA COS and believed that its implementation would improve research quality; however, incentives for routine implementation were reported to be lacking. Findings will guide future revisions of the ROMA COS and the development of theoretically informed implementation strategies. Supplemental Material https://doi.org/10.23641/asha.16528524.
