Development of a core outcome set for clinical trials aimed at improving antimicrobial stewardship in care homes

ABSTRACT:

Background

Diverse outcomes reported in clinical trials of antimicrobial stewardship (AMS) interventions in care homes have hindered evidence synthesis. Our main objective was to develop a core outcome set (COS) for use in trials aimed at improving AMS in care homes.

Methods

A refined inventory of outcomes for AMS interventions in care homes, compiled from a previous study, was rated in a three-round international Delphi survey with 82 participants, using a nine-point Likert scale (from 1, unimportant, to 9, critical). This was followed by an online consensus exercise with 12 participants from Northern Ireland to finalise the COS content. Subsequently, a suitable outcome measurement instrument (OMI) was selected for each outcome in the COS by: identifying existing OMIs through a literature search and experts’ suggestions, assessing the quality of OMIs, and selecting one OMI for each core outcome via a two-round international Delphi survey with 59 participants.

Results

Of 14 outcomes initially presented, consensus was reached for inclusion of five outcomes in the COS after the three-round Delphi survey and the online consensus exercise, comprising the total number of antimicrobial courses prescribed, appropriateness of antimicrobial prescribing, days of therapy per 1000 resident-days, rate of antimicrobial resistance, and mortality related to infection. Of 17 potential OMIs identified, three were selected for the two-round Delphi exercise after the quality assessment. Consensus was reached for selection of two OMIs for the COS.

Conclusion

This COS is recommended to be used in clinical trials aimed at improving AMS in care homes.

Project description:ObjectivesMore children are surviving critical illness but are at risk of residual or new health conditions. An evidence-informed and stakeholder-recommended core outcome set is lacking for pediatric critical care outcomes. Our objective was to create a multinational, multistakeholder-recommended pediatric critical care core outcome set for inclusion in clinical and research programs.DesignA two-round modified Delphi electronic survey was conducted with 333 invited research, clinical, and family/advocate stakeholders. Stakeholders completing the first round were invited to participate in the second. Outcomes scoring greater than 69% "critical" and less than 15% "not important" advanced to round 2 with write-in outcomes considered. The Steering Committee held a virtual consensus conference to determine the final components.SettingMultinational survey.PatientsStakeholder participants from six continents representing clinicians, researchers, and family/advocates.Measurements and main resultsOverall response rates were 75% and 82% for each round. Participants voted on seven Global Domains and 45 Specific Outcomes in round 1, and six Global Domains and 30 Specific Outcomes in round 2. Using overall (three stakeholder groups combined) results, consensus was defined as outcomes scoring greater than 90% "critical" and less than 15% "not important" and were included in the final PICU core outcome set: four Global Domains (Cognitive, Emotional, Physical, and Overall Health) and four Specific Outcomes (Child Health-Related Quality of Life, Pain, Survival, and Communication). Families (n = 21) suggested additional critically important outcomes that did not meet consensus, which were included in the PICU core outcome set-extended.ConclusionsThe PICU core outcome set and PICU core outcome set-extended are multistakeholder-recommended resources for clinical and research programs that seek to improve outcomes for children with critical illness and their families.

Project description:BackgroundAntimicrobial resistance is both a global public health and patient safety problem driven by overprescribing of antibiotic and other antimicrobial drugs. To conserve the effectiveness of antibiotics for future generations, antibiotic stewardship approaches to using them only where appropriate and necessary are advocated. Dentistry accounts for about 10% of antibiotic prescriptions across global healthcare, with 80% not in accordance with guidance in some countries. Core outcome sets enable the results of studies to be compared in order to maximise the value which can be derived from them. The aim of this study is to develop an international consensus on a core outcome set for dental antibiotic stewardship.MethodsConsensus on outcomes which are critical for inclusion in the core outcome set for dental antibiotic stewardship will be sought through two rounds of a Delphi survey (using the DelphiManager online system) followed by a final online consensus meeting. Thirty participants will be recruited to the Delphi Panel from across three stakeholder groups: ten dentists, ten academics and ten adults experienced with dental antibiotics as either a patient or parent/carer of a patient who has been prescribed them. Consensus will be achieved if more than 70% of the panel agree that an outcome is critical, with at least one from each stakeholder group in agreement. A long-list of candidate core outcomes has been developed from previously published studies with additions recommended by the steering group. The steering group will oversee development of the core outcome set and includes people from around the world with experience of dental antibiotics: clinicians, researchers and people with experience of being prescribed dental antibiotics and/or surviving an antibiotic resistant infection.DiscussionTo date, few studies of dental antibiotic stewardship have been published. Internationally, dental antibiotic guidelines and patterns of use vary widely, so a core outcome set is particularly important to facilitate meaningful comparisons between studies. This core outcome set will encompass antibiotic prescribing for both therapeutic indications, such as for people with acute infections, and for prophylactic indications, such as the prevention of distant site infections (like infective endocarditis) following dental procedures.

Project description:BackgroundPeople living in care homes have experienced devastating impact from COVID-19. As interventions to prevent the transmission of COVID-19 are developed and evaluated, there is an urgent need for researchers to agree on the outcomes used when evaluating their effectiveness. Having an agreed set of outcomes that are used in all relevant trials can ensure that study results can be compared.ObjectiveThe aim of the study was to develop a core outcome set (COS) for trials assessing the effectiveness of pharmacological and non-pharmacological interventions for preventing COVID-19 infection and transmission in care homes.MethodsThe study used established COS methodology. A list of candidate outcomes was identified by reviewing registered trials to evaluate interventions to prevent COVID-19 in care homes. Seventy key stakeholders participated in a Delphi survey, rating the candidate outcomes on a nine-point scale over two rounds, with the opportunity to propose additional outcomes. Stakeholders included care home representatives (n = 19), healthcare professionals (n = 20), people with personal experience of care homes (n = 7), researchers (n = 15) and others (n = 9). Outcomes were eligible for inclusion if they met an a priori threshold. A consensus meeting with stakeholders resulted in agreement of the final outcome set.ResultsFollowing the Delphi and consensus meeting, twenty-four outcomes were recommended for inclusion. These are grouped across four domains of infection, severity of illness, mortality, and 'other' (intervention specific or life impact). Due to the considerable heterogeneity between care homes, residents, and interventions, the relevance and importance of outcomes may differ between trial contexts. Intervention-specific outcomes would be included only where relevant to a given trial, thus reducing the measurement burden.ConclusionUsing a rapid response approach, a COS for COVID-19 prevention interventions in care homes has been developed. Future work should focus on identifying instruments for measuring these outcomes, and the interpretation and application of the COS across different trial contexts. Beyond COVID-19, the outcomes identified in this COS may have relevance to other infectious diseases in care homes, and the rapid response approach may be useful as preparation for future pandemics.

Project description:BackgroundBronchiectasis is a chronic respiratory disease characterised by airways widening and recurrent infections, resulting in episodes of chronic cough, sputum expectoration, and dyspnoea. This leads to deterioration in daily function, repeated hospital admissions and poor quality of life. The prevalence and mortality related to bronchiectasis is increasing worldwide with growing economic burden on healthcare systems. Physiotherapy for bronchiectasis aims to decrease accumulation of sputum, dyspnoea, and improve exercise capacity and daily function. A robust evidence base to support physiotherapy in bronchiectasis is currently lacking. This is partly because of inconsistency and poor reporting of outcomes in available studies. A core outcome set is the minimum acceptable group of outcomes that should be used in clinical trials for a specific condition. This decreases research waste by improving consistency and reporting of key outcomes and facilitates the synthesis of study outcomes in systematic reviews and guidelines. The aim of the study is therefore to develop a core outcome set and outcome measurement set for physiotherapy research in adults with bronchiectasis. This will ensure outcomes important to key stakeholders are consistently used and reported in future research.Methods and analysisThis project will use the COMET Initiative and COSMIN guidelines of core outcome set development and will include three phases. In the first phase, a comprehensive list of outcomes will be developed using systematic review of reported outcomes and qualitative interviews with patients and physiotherapists. Then consensus on key outcomes will be established in phase two using a Delphi survey and a consensus meeting. Finally, in phase three, we will identify appropriate instruments to measure the core outcomes by evaluating the psychometric properties of available instruments and a stakeholders' meeting to establish consensus.EthicsThe study was reviewed and has received ethical approval from the health-related Research Ethics Committee- Edge Hill University (ETH2021-0217).RegistrationThis study is registered with the COMET database. https://www.comet-initiative.org/Studies/Details/1931.
