Barriers and facilitators to healthcare professional behaviour change in clinical trials using the Theoretical Domains Framework: a case study of a trial of individualized temperature-reduced haemodialysis

Barriers and facilitators to using a clinical decision support tool for the management of osteoarthritis pain in patients undergoing hemodialysis: a qualitative study

BACKGROUND

While osteoarthritis is a significant issue within the hemodialysis population and contributes to reduced quality of life, pain related to osteoarthritis is poorly managed by healthcare professionals (HCPs) in hemodialysis settings due to the absence of clinical guidance applicable to this population. The purpose of this study was to explore the perceptions of HCPs on the barriers and facilitators to using a clinical decision support tool for osteoarthritis pain management in the hemodialysis setting.

METHODS

A qualitative descriptive study was conducted. Purposeful and snowball sampling techniques were used to recruit hemodialysis clinicians from academic and community settings across multiple Canadian provinces. One-to-one interviews were conducted with clinicians using a semi-structured, open ended interview guide informed by the Theoretical Domains Framework, a behavior change framework. A general inductive approach was applied to identify the main themes of barriers and facilitators.

RESULTS

A total of 11 interviews were completed with 3 nephrologists, 2 nurse practitioners and 6 pharmacists. Findings revealed 6 main barriers and facilitators related to the use of the clinical decision support tool. Alignment of the tool with practice roles emerged as a key barrier and facilitator. Other barriers included challenges related to the dialysis environment, varying levels of clinician comfort with pain medications, and limited applicability of the tool due to patient factors. An important facilitator was the intrinsic motivation among clinicians to use the tool.

CONCLUSIONS

Most participants across the included hemodialysis settings expressed satisfaction with the clinical decision support tool and acknowledged its overall potential for improving osteoarthritis pain management among patients on hemodialysis. Future implementation of the tool may be limited by existing roles and practices at different institutions. Increased collaboration among hemodialysis and primary care teams may promote uptake of the tool.

The Ottawa Statement implementation guidance document for cluster randomized trials in the hemodialysis setting

Research teams are increasingly interested in using cluster randomized trial (CRT) designs to generate practice-guiding evidence for in-center maintenance hemodialysis. However, CRTs raise complex ethical issues. The Ottawa Statement on the Ethical Design and Conduct of Cluster Randomized Trials, published in 2012, provides 15 recommendations to address ethical issues arising within 7 domains: justifying the CRT design, research ethics committee review, identifying research participants, obtaining informed consent, gatekeepers, assessing benefits and harms, and protecting vulnerable participants. But applying the Ottawa Statement recommendations to CRTs in the hemodialysis setting is complicated by the unique features of the setting and population. Here, with the help of content experts and patient partners, we co-developed this implementation guidance document to provide research teams, research ethics committees, and other stakeholders with detailed guidance on how to apply the Ottawa Statement recommendations to CRTs in the hemodialysis setting, the result of a 4-year research project. Thus, our work demonstrates how the voices of patients, caregivers, and all stakeholders may be included in the development of research ethics guidance.

Does cooled dialysate still have a role in reducing intradialytic stress? Implications of the MyTEMP trial

PURPOSE OF REVIEW

There is an excess of cardiovascular morbidity and mortality in the maintenance haemodialysis population. Targeting traditional risk factors (e.g. hypercholesterolaemia) do not improve cardiovascular outcomes. Repeated myocardial stunning during haemodialysis is an important nontraditional risk, resulting in pathological cardiac remodelling and fibrosis. This review explores dialysate cooling as a management strategy to promote haemodynamic stability, reduce myocardial injury, and improve cardiovascular disease outcomes for individuals receiving maintenance haemodialysis.

RECENT FINDINGS

Observational data and small interventional studies demonstrate dialysate cooling has the potential to reduce end-organ damage and provide cardioprotection, renal protection and neuroprotection compared with standard care. These data are limited by the small sample sizes, short follow-up times and lack of long-term patient important outcomes. The MyTEMP study, a multicentre pragmatic randomized controlled trial, demonstrated cooled dialysate (0.5°C below body temperature) vs. standard care did not improve cardiovascular outcomes for prevalent haemodialysis patients.

SUMMARY

Dialysate cooling has been widely adopted into routine clinical practice; the MyTEMP study challenges the unit-level approach to implementing dialysate cooling. Due to methodological limitations, the absence of other important patient outcome measures, and lack of granularity of patient-level data, dialysate cooling should not be hastily removed from all dialysis care and warrants further research.

Challenges and opportunities for conducting pre-hospital trauma trials: a behavioural investigation

BACKGROUND

Trials in pre-hospital trauma care are relatively uncommon. There are logistical and methodological challenges related to designing and delivering trials in this setting. Previous studies have assessed challenges reported in individual trials rather than across the pre-hospital trial landscape to identify over-arching factors. The aim of this study was to investigate the challenges and opportunities related to the set-up, design and conduct of pre-hospital trauma trials from across the pre-hospital trial landscape and a specific pre-hospital trauma feasibility study.

METHODS

Semi-structured interviews were conducted with two cohorts of participants: research personnel who had experience of pre-hospital trials, either through direct involvement in conduct or through strategic oversight of national initiatives (n = 7), and clinical staff (n = 16) involved in recruitment to a pre-hospital trauma feasibility study. Thematic analyses were used to assess the barriers and enablers of conducting pre-hospital trauma trials. Two frameworks (The Capability Opportunity Motivation-Behaviour and the Theoretical Domains Framework) were used to guide analyses.

RESULTS

The barriers and enablers reported were relevant to several TDF domains and COM-B components. Across both cohorts, challenges associated with opportunities were reported and included the lack of research experience amongst pre-hospital staff, team dynamics within a rotating shift schedule, and the involvement of external organisations with diverse institutional priorities and infrastructures (e.g. Air Ambulances). The infrequency of eligible cases was also reported to affect the trial design, set-up, and conduct. Other barriers reported related to clinical equipoise amongst staff and institutional pressures, which affected motivation.

CONCLUSIONS

This study has highlighted that pre-hospital trials face many context-specific but also generic challenges. Pre-hospital trauma trial teams could consider the findings to develop targeted, behaviourally focused, solutions to the challenges identified in order to enhance the set-up and conduct of trials in this setting.

Barrieren und Förderfaktoren für die Implementierung eines Konzepts zur Förderung evidenzbasierten Arbeitens in der Physiotherapie – Eine Mixed-Methods-Studie

Hintergrund In der Physiotherapie in Deutschland besteht Bedarf an theoretisch und wissenschaftlich fundierten Implementierungsstrategien zur Förderung des evidenzbasierten Arbeitens (EBP). Bei der Entwicklung solcher Strategien ist es notwendig, die Rahmenbedingungen und Einflussfaktoren im individuellen Kontext zu erfassen und zu berücksichtigen. In diesem Zusammenhang wurde das „science4practice“-Konzept mit dem Ziel entwickelt, die Umsetzung von EBP in physiotherapeutischen Einrichtungen zu fördern.

Ziel Erhebung von Barrieren und Förderfaktoren für die Implementierung des „science4practice“-Konzepts.

Methode Im Rahmen einer Mixed-Methods-Studie wurden qualitative, semistrukturierte Interviews sowie eine quantitative Erhebung anhand eines Online- und Papierfragebogens durchgeführt. An den Interviews nahmen Geschäfts- und Therapieleitungen therapeutischer Einrichtungen sowie Physiotherapeut*innen ohne Leitungsverantwortung teil. An der quantitativen Befragung nahmen Physiotherapeut*innen ohne Leitungsverantwortung teil. Die Daten der Interviews wurden mittels thematischer Inhaltsanalyse ausgewertet. Die Daten der quantitativen Erhebung wurden deskriptiv analysiert.

Ergebnisse Aus den 15 durchgeführten Interviews konnten die mangelnden Fähigkeiten zur Literaturrecherche und -bewertung, negative Erfahrungen mit Veränderungsprozessen sowie unzureichende Zugangsmöglichkeiten zu wissenschaftlicher Literatur als Barrieren abgeleitet werden. Als Förderfaktoren wurden die Unterstützung durch Vorgesetzte sowie die Verfügbarkeit von Ressourcen für die Implementierung des Konzepts identifiziert. Die Umfrageergebnisse von 47 Physiotherapeut*innen ohne Leitungsverantwortung zeigen kumulierte Zustimmungswerte („trifft voll zu“ und „trifft eher zu“) von 83–91 % für die Bereitschaft zur Umsetzung des „science4practice“-Konzepts. Durch die Zusammenführung der quantitativen und qualitativen Daten konnte die Bereitschaft des Teams zur Konzeptumsetzung abschließend als Förderfaktor eingeordnet werden.

Schlussfolgerung Die Studie identifiziert Barrieren und Förderfaktoren aus Sicht der Teilnehmenden mit und ohne Leitungsverantwortung. Einerseits unterstreichen die Daten national und international identifizierte Barrieren wie mangelnde wissenschaftliche Kompetenzen oder unzureichende Zugänge zu wissenschaftlicher Literatur. Andererseits zeigen die Ergebnisse das Potential des Konzepts als EBP-Implementierungsvorhaben in der Physiotherapie in Deutschland. Im nächsten Schritt sollten Studien durchgeführt werden, um die Machbarkeit des Konzepts zu überprüfen.

Personalised cooler dialysate for patients receiving maintenance haemodialysis (MyTEMP): a pragmatic, cluster-randomised trial

BACKGROUND

Haemodialysis centres have conventionally provided maintenance haemodialysis using a standard dialysate temperature (eg, 36·5°C) for all patients. Many centres now use cooler dialysate (eg, 36·0°C or lower) for potential cardiovascular benefits. We aimed to assess whether personalised cooler dialysate, implemented as centre-wide policy, reduced the risk of cardiovascular-related death or hospital admission compared with standard temperature dialysate.

METHODS

MyTEMP was a pragmatic, two-arm, parallel-group, registry-based, open-label, cluster-randomised, superiority trial done at haemodialysis centres in Ontario, Canada. Eligible centres provided maintenance haemodialysis to at least 15 patients a week, and the medical director of each centre had to confirm that their centre would deliver the assigned intervention. Using covariate-constrained randomisation, we allocated 84 centres (1:1) to use either personalised cooler dialysate (nurses set the dialysate temperature 0·5-0·9°C below each patient's measured pre-dialysis body temperature, with a lowest recommended dialysate temperature of 35·5°C), or standard temperature dialysate (36·5°C for all patients and treatments). Patients and health-care providers were not masked to the group assignment; however, the primary outcome was recorded in provincial databases by medical coders who were unaware of the trial or the centres' group assignment. The primary composite outcome was cardiovascular-related death or hospital admission with myocardial infarction, ischaemic stroke, or congestive heart failure during the 4-year trial period. Analysis was by intention to treat. The study is registered at ClinicalTrials.gov, NCT02628366.

FINDINGS

We assessed all of Ontario's 97 centres for inclusion into the study. Nine centres had less than 15 patients and one director requested that four of their seven centres not participate. 84 centres were recruited and on Feb 1, 2017, these centres were randomly assigned to administer personalised cooler dialysate (42 centres) or standard temperature dialysate (42 centres). The intervention period was from April 3, 2017, to March 31, 2021, and during this time the trial centres provided outpatient maintenance haemodialysis to 15 413 patients (about 4·3 million haemodialysis treatments). The mean dialysate temperature was 35·8°C in the cooler dialysate group and 36·4°C in the standard temperature group. The primary outcome occurred in 1711 (21·4%) of 8000 patients in the cooler dialysate group versus 1658 (22·4%) of 7413 patients in the standard temperature group (adjusted hazard ratio 1·00, 96% CI 0·89 to 1·11; p=0·93). The mean drop in intradialytic systolic blood pressure was 26·6 mm Hg in the cooler dialysate group and 27·1 mm Hg in the standard temperature group (mean difference -0·5 mm Hg, 99% CI -1·4 to 0·4; p=0·14).

INTERPRETATION

Centre-wide delivery of personalised cooler dialysate did not significantly reduce the risk of major cardiovascular events compared with standard temperature dialysate. The rising popularity of cooler dialysate is called into question by this study, and the risks and benefits of cooler dialysate in some patient populations should be clarified in future trials.

Effectiveness of public health education on the uptake of iron and folic acid supplements among pregnant women: a stepped wedge cluster randomised trial

INTRODUCTION

Iron deficiency is the most prevalent micronutrient deficiency in pregnancy globally responsible for nearly 120 000 maternal deaths per year and a fifth of maternal mortality. Over 46% of pregnant women in Africa and 62% of pregnant women in Kenya are anaemic. Anaemia has severe economic and health consequences. Daily iron and folic acid supplementation (IFAS) is an efficacious strategy recommended in pregnancy to reduce the risk of anaemia and improve maternal and neonatal survival. However, most pregnant women do not consume IFAS as recommended. Limited knowledge on IFAS, its benefits and its connection with anaemia, and mitigation of its side effects lead to poor consumption. The main objective of this trial is to determine the effectiveness of public health education on uptake of antenatal IFAS.

METHODS AND ANALYSIS

A stepped wedge cluster randomised trial with antenatal clinics as units of randomisation. Twelve clusters will be randomised to receive the intervention and levels of IFAS uptake compared with preintervention period. The 9-month trial will enrol 1205 pregnant women. The primary outcome will be the proportion of pregnant women effectively taking up IFAS measured through self-reports, residual pill count and inspection of pill reminder cards. Routine clinical data on haemoglobin counts and fetal growth monitoring will also be used. Descriptive and bivariate analysis will be conducted in Stata using Pearson's χ2 test for association, and multivariate logistic regression to identify determinants of uptake. The potential public health benefits will be estimated using the number needed to treat and the preventable fraction.

ETHICS AND DISSEMINATION

Ethical approval was granted by Kenyatta University Ethics Review Committee (PKU/2443/11575). The research permit is obtained from Kenya National Commission for Science, Technology and Innovation (NACOSTI/P/22/16168). Findings will be disseminated through peer-reviewed publications and public health conferences.

Identifying barriers and enablers to opt-out hepatitis C virus screening in provincial prisons in Quebec, Canada: A multilevel, multi-theory informed qualitative study with correctional and healthcare professional stakeholders

BACKGROUND

Diffuse implementation of hepatitis C virus (HCV) treatment is dependent on universal screening for HCV, but screening strategies are heterogenous across prisons in the province of Quebec (Canada). We sought to identify barriers and enablers to universal opt-out HCV screening and to describe the multisectoral decision-making processes related to HCV screening in Quebec provincial prisons.

METHODS

A multilevel, multi-theory informed qualitative descriptive approach was used to conduct semi-structured interviews. Interview guides and analyses with correctional stakeholders were informed by the Consolidated Framework for Implementation Research (CFIR) and those with healthcare professionals (HCPs) were based on the Theoretical Domains Framework (TDF). Directed content analysis was used to identify domains within CFIR and TDF reflecting barriers and enablers to opt-out HCV screening.

RESULTS

Sixteen interviews (correctional stakeholders: n = 8; HCPs: n = 8) were conducted in April-May 2021. Twelve CFIR constructs were identified as barriers, seven as enablers, and two as neutral factors for the implementation of opt-out HCV screening. Correctional stakeholders underscored the need for political will (construct: external policy and incentives), highlighted limited resources (construct: available resources), and expressed concerns for the lack of consideration of implementation issues (constructs: trialability, planning). Six TDF domains were identified among HCPs as relevant to the implementation of opt-out HCV screening: beliefs about consequences (mixed = enablers and barriers), environmental context and resources (barrier), social influences (barrier), optimism (mixed), emotions (mixed), and behavioural regulation (barrier). The decision-making processes vis-à-vis HCV care in Quebec correctional settings were found to be hierarchical and complex.

CONCLUSIONS

The use of CFIR and TDF was helpful in identifying barriers and enablers to HCV screening at multiple levels for people incarcerated in Quebec provincial prisons. Going forward, several political, structural, and organizational factors should be addressed through the engagement of stakeholders and people with lived experience of incarceration.

Behavioural optimisation to address trial conduct challenges: case study in the UK-REBOA trial

BACKGROUND

Clinical trials comprise multiple processes at various stages of the trial lifecycle. These processes often involve complex behaviours such as recruiting vulnerable patient populations and clinicians having to deliver complex trial interventions successfully. Few studies have utilised a behavioural framework to assess challenges and develop strategies for effective trial recruitment and delivery of trial interventions. This study reports the application of an innovative methodological approach to understand core trial processes, namely recruitment and intervention delivery, using a behavioural science approach to develop strategies designed to mitigate trial process problems.

METHODS

The UK-REBOA trial aims to evaluate the clinical and cost-effectiveness of resuscitative endovascular balloon occlusion of the aorta (a novel intervention) in injured patients with exsanguinating haemorrhage. A behavioural investigation ('diagnosis') was conducted using theory-informed (Theoretical Domains Framework, TDF) semi-structured interviews with site staff from the UK-REBOA trial to examine trial processes which could be improved in relation to trial recruitment and delivery of the intervention. Interviews were analysed using the TDF to identify influences on behaviour, which were then mapped to techniques for behaviour change and developed into potential solutions.

RESULTS

The behavioural diagnosis of the challenges experienced during trial processes highlighted factors relevant to a range of TDF domains: Skills, Environmental context and resources, Beliefs about capabilities, Beliefs about consequences, Social influences, and Memory, attention, and decision-making processes. Within the solution development phase, we identified 24 suitable behaviour change techniques that were developed into proposed solutions to target reported process problems with the aim of changing behaviour to improve recruitment and/or intervention delivery. Proposed solutions included targeted changes to trial training content, suggestions to restructure the environment (e.g. reinforced the purpose of the trial with information about the social and environmental consequences) and other strategies to reduce barriers to recruitment and intervention delivery.

CONCLUSIONS

This study demonstrates the feasibility of applying a behavioural approach to investigate ('diagnose') behavioural trial process problems and subsequently develop and implement targeted solutions ('treatment') in an active trauma trial. Understanding the factors that affected behaviour, attitudes and beliefs in this trauma trial allowed us to implement theoretically informed, evidence-based solutions designed to enhance trial practices.

Theory-guided interviews identified behavioral barriers and enablers to healthcare professionals recruiting participants to maternity trials

OBJECTIVE

To conduct a behavioral investigation, using the Theoretical Domains Framework (TDF), to identify barriers and enablers to maternity healthcare professionals (HCP) inviting all eligible women to participate in a maternity care trial.

STUDY DESIGN AND SETTING

We invited HCP recruiters from maternity care trials in high priority research areas including, diabetes, preeclampsia and breastfeeding, from across Ireland and the UK, to take part in a semi-structured interview. Data collection was informed by the TDF, followed by inductive thematic analysis and deductive mapping to the TDF.

RESULTS

Twenty-two recruiters including midwives, nurses, allied health professionals and doctors were interviewed online or by telephone phone. Thematic analysis generated four global themes; Availability and accessibility of resources, Navigating the recruitment pathway, Prioritising clinical responsibilities over research responsibilities and The influence of colleagues and peers. Themes were mapped to the TDF, identifying 13 domains relevant to the behaviour.

CONCLUSION

This paper identifies the factors enabling or inhibiting maternity HCP recruiters to invite all eligible women to participate in a maternity care trial. The findings provide guidance for researchers designing trials for this population and the essential first step in developing a recruiter-focused behaviour change intervention to support recruitment to trials in maternity care.

Understanding potential barriers and enablers to a perioperative early phase cell therapy trial

BACKGROUND AIMS

Early-phase cell therapy clinical trials depend on patient and physician involvement, yet barriers can impede their participation.

METHODS

To optimize engagement for a planned cell therapy trial to prevent perioperative cardiac complications, the authors conducted semi-structured interviews with at-risk patients and physicians who could potentially be involved in the study. The authors used the theoretical domains framework to systematically identify potential barriers and enablers.

RESULTS

Forty-one interviews were conducted to reach data saturation, and four overall potential barriers to participation (themes) were identified. Theme 1 emphasizes that patients and physicians need accessible information to better understand the benefits and risks of the novel therapy and trial procedures and to address misconceptions. Theme 2 underscores the need for clarity on whether the trial's primary purpose is safety or efficacy, as this may influence patient and physician decisions. Theme 3 recognizes the resource and logistic realities for patients (e.g., convenient follow-up appointments) and physicians (e.g., personnel to assist in trial procedures, competing priorities). Theme 4 describes the importance of social influences (e.g., physicians and family, peers/colleagues) that may affect decisions to participate and the importance of patient preferences (e.g., availability of physicians to discuss the trial, including caregivers in discussions).

CONCLUSIONS

Prospectively addressing these issues may help optimize feasibility prior to conducting an expensive, resource-intensive trial.

Do pharmacy practice standards effectively describe behaviour? Reviewing practice standards using a behavioural specificity framework

Background

Guidelines and practice standards exist to communicate the conduct and behaviour expected of health care professionals and ensure consistent quality practice. It is important that they describe behaviours explicitly so they can be interpreted, enacted and measured with ease. The AACTT framework specifies behaviour in terms of the: Action to be performed, Actor who performs the action, Context where the action occurs, Target who the action is performed with/for and Time when the action is performed (AACTT). It provides the most up to date framework for specifying behaviours and is particularly relevant to complex behavioural problems that involve sequences of behaviours performed by different people. Behavioural specificity within pharmacy practice standards has not been explored.

Aim

To determine if behaviours described in the Professional Practice Standards for Australian Pharmacists specify Action, Actor, Context, Target and Time.

Methods

Two researchers independently reviewed the scope and structure of the practice standards and one extracted action statements (behaviours) verbatim. Through an iterative process, the researchers modified and developed the existing AACTT definitions to operationalise them for application to review of the action statements in the practice standards. The operational definitions, decision criteria and curated examples were combined in a codebook. The definitions were consistently applied through a directed content analysis approach to evaluate all extracted action statements by one researcher. For consistency 20% was independently checked for agreement by a second researcher.

Results

A novel codebook to apply AACTT criteria to evaluate practice standards was developed. Application of this codebook identified 768 independent behaviours. Of these, 300 (39%) described at least one discrete observable action, none specified an actor, 25 (3%) specified context, 131 (17%) specified target and 88 (11%) specified time.

Conclusion(s)

The behaviours detailed in practice standards for Australian pharmacists do not consistently specify behaviours in terms of Action, Actor, Context, Target and Time. Developers in the pharmacy profession, and beyond, should consider the behavioural specificity of their documents to improve interpretability, usability and adherence to the behaviours detailed. This also has implications for the development and evaluation of interventions to change such behaviours and improve quality of care.

Extrinsic and intrinsic factors acting as barriers or facilitators in nurses' implementation of clinical practice guidelines: a mixed-method systematic review

BACKGROUND AND AIM OF THE WORK

Greater evaluations are needed to identify barriers or facilitators in nurses' guidelines adherence. The current review aims to explore extrinsic and intrinsic factors impacting nurses' compliance.

METHODS

Mixed-method systematic review with a convergent approach, following the PRISMA checklist and the JBI Mixed Methods Review Methodological Guidance was conducted. MEDLINE, Embase, CINAHL were systematically searched, to find studies published between 2010 and 2021, including qualitative, quantitative or mixed-methods articles.

RESULTS

Sixty studies were included, and the major findings were analysed by aggregating them in two main themes: intrinsic and extrinsic factors. The intrinsic factors were: a) knowledge and skills; b) attitudes of health personnel; c) sense of belonging towards guidelines. The extrinsic factors were: a) organizational and environmental factors; b) workload; c) guidelines structure; d) patients and caregivers' attitude.

CONCLUSIONS

The included studies report lack of resources, among environmental factors, as the main barrier perceived. Nurses, who are at the forefront in addressing the direct application of knowledge and skills to ensure patient safety, have a higher perception of this kind of barriers than other healthcare personnel. Potential facilitators emerged in the review are positive feedback and reinforcements at the workplace, either from the members of the team or from the leaders. Moreover, the level of active participation of the patient and caregiver could have a positive impact on nurses' guidelines adherence. Guidelines implementation remains a complex process, resulting in a strong recommendation to support health policymakers and nursing leaders in implementing continuing education programs.

From intention to action: A systematic literature review of provider behaviour change-focused interventions in physical health and behavioural health settings

RATIONALE, AIMS AND OBJECTIVES

It is clear there are significant delays in the uptake of best practices as part of routine care in the healthcare system, yet there is conflicting evidence on how to specifically align provider behaviour with best practices.

METHOD

We conducted a review of interventions utilized to change any aspect of provider behaviour. To extend prior research, studies were included in the present review if they had an active intervention targeting behaviour change of providers in health or behavioural-health settings and were published between 2001 and 2020.

RESULTS

Of 1547 studies, 44 met inclusion criteria. Of 44 studies identified, 28 studies utilized contextually relevant interventions (eg, tailored to a specific provider population). Twenty six interventions with a contextually relevant approach resulted in provider behaviour change.

CONCLUSIONS

Findings are promising for encouraging provider behaviour change when interventions are tailored to be contextually relevant, as both single-component and multifaceted interventions were successful when they were contextually relevant. It is critical to conduct additional research to ensure that providers sustain behaviour changes over a long-term beyond an intervention's implementation and evaluation period.

Modelling enablers of efficiency and sustainability of healthcare: a m-TISM approach

Purpose

It would not be an exaggeration to say that healthcare is the most crucial one in today's perspective. The healthcare sector, in general, is engaged in working on various dimensions simultaneously like the safety, care, quality and cost of services, etc. Still, the desired outcomes from this sector are far away, and it becomes pertinent to address all such issues associated with healthcare on a priority basis for sustaining the outcomes in a long-term perspective. The present study aims to explore the healthcare sector and list out the directly associated enablers contributing to increasing the viability of the healthcare sector. Besides, the interrelationship among the enlisted enablers needs to be studied, which further helps in setting-out the priority to deal with individual enablers based on their impedance in the contribution towards viability increment.

Design/methodology/approach

The authors have done an extensive review to list out the enablers of the healthcare sector to perform efficiently and effectively. Further, the attempt has been made on the enablers to rank them by using the modified Total Interpretative Structure Modelling (m-TISM) approach. The validation of the study reveals the importance of enablers based on their position in the hierarchical structure. Further, the MICMAC analysis on the identified enabler is performed to categorize the identified enablers in the different clusters based on their driving power and dependence.

Findings

The research tries to envisage the importance of the healthcare sector and its contribution towards national development. The outcomes of the m-TISM model in the present study reveal the noteworthy contribution of the organizational structure in managing the healthcare facilities and represented it as the perspective of future growth. The well-designed organizational structure in the healthcare industry helps in establishing better employee–employer cooperation, workforce coordination and inter-department cooperation.

Research limitations/implications

Every research work has limitations. Likewise, the present research work also has limitations, i.e. input taken for developing the models are from very few experts that may not reflect the opinion of the whole sector.

Practical implications

The healthcare sector is the growing sector in the present-day scenario, and it is essential to keep the quality of treatment in check along with the quantity. The present study has laid down the practical foundations for improvement in the healthcare sector viability. Besides, the study emphasized on accountability of the healthcare sector officials to go with the enablers having the strong driving power for effective utilization of all the resources. This would further help them in customer (patients) satisfaction.

Originality/value

Despite an increase in demand for good quality healthcare facilities worldwide, the growth of this sector is bounded by the economic, demographic, cultural and environmental concerns, etc. The present study proposed a unique framework that provides a better understanding of the enablers. It would further help in playing a key role in increasing the viability of the healthcare sector. The hierarchy developed with the help of m-TISM and MICMAC analysis will help the viewers to recognize the important enablers based on their contribution to the viability improvement of the healthcare sector.

Barriers and facilitators affecting implementation of the Canadian clinical practice guidelines for the diagnosis of acute aortic syndrome

BACKGROUND

Acute aortic syndrome (AAS) is an uncommon, life-threatening emergency that is frequently misdiagnosed. The 2020 Canadian clinical practice guidelines for the diagnosis of AAS incorporate all available evidence into four key recommendations. In order to facilitate the implementation of these recommendations, a clinical decision aid was created. The objective of this study was to identify barriers and facilitators among physicians prior to implementation of the guideline recommendations in a multicentre step wedge cluster randomized control trial.

METHODS

We conducted semi-structured interviews with nine emergency room physicians working at five sites distributed between urban academic and rural settings. We used purposive sampling, contacting physicians until data saturation was reached. Interview questions were designed to understand potential barriers and facilitators to guideline recommendation uptake and use. Responses were analysed according to the Theoretical Domains Framework, and overarching themes describing these barriers and facilitators were identified.

RESULTS

Two themes and six subthemes encompassing 13 theoretical domains were identified. These included clinical decision-making support, awareness of the evidence, social factors, expected consequences, ability of physicians to acquire the necessary data and ease of use. A majority of interviewees anticipated that the guideline recommendations would support clinical decision making and more effectively risk-stratify patients. Other facilitators included endorsement of the guidelines by professional organizations and peers. Barriers to implementation include the fact that laboratory testing and knowledge of the rationale for its use in the investigation of AAS were not widespread. The complexity of the clinical decision aid and concerns about test specificity were also identified as potential barriers to use.

CONCLUSION

Physicians were amenable to using the AAS guideline recommendations to support clinical decision-making and to reduce resource use. A structured intervention should be developed to address the identified barriers and leverage the facilitators in order to ensure successful implementation. Our findings may have implications for the implementation of other guidelines used in emergency departments.

Barriers and enablers to effective interprofessional teamwork in the operating room: A qualitative study using the Theoretical Domains Framework

Background

Effective teamwork is critical for safe, high-quality care in the operating room (OR); however, teamwork interventions have not consistently resulted in the expected gains for patient safety or surgical culture. In order to optimize OR teamwork in a targeted and evidence-based manner, it is first necessary to conduct a comprehensive, theory-informed assessment of barriers and enablers from an interprofessional perspective.

Methods

This qualitative study was informed by the Theoretical Domains Framework (TDF). Volunteer, purposive and snowball sampling were conducted primarily across four sites in Ontario, Canada and continued until saturation was reached. Interviews were recorded, transcribed, and de-identified. Directed content analysis was conducted in duplicate using the TDF as the initial coding framework. Codes were then refined whereby similar codes were grouped into larger categories of meaning within each TDF domain, resulting in a list of domain-specific barriers and enablers.

Results

A total of 66 OR healthcare professionals participated in the study (19 Registered Nurses, two Registered Practical Nurses, 17 anaesthesiologists, 26 surgeons, two perfusionists). The most frequently identified teamwork enablers included people management, shared definition of teamwork, communication strategies, positive emotions, familiarity with team members, and alignment of teamwork with professional role. The most frequently identified teamwork barriers included others’ personalities, gender, hierarchies, resource issues, lack of knowledge of best practices for teamwork, negative emotions, conflicting norms and perceptions across professions, being unfamiliar with team members, and on-call/night shifts.

Conclusions

We identified key factors influencing OR teamwork from an interprofessional perspective using a theoretically informed and systematic approach. Our findings reveal important targets for future interventions and may ultimately increase their effectiveness. Specifically, achieving optimal teamwork in the OR may require a multi-level intervention that addresses individual, team and systems-level factors with particular attention to complex social and professional hierarchies.

Using behavioral theory and shared decision-making to understand clinical trial recruitment: interviews with trial recruiters

BACKGROUND

Clinical trial recruitment is a continuing challenge for medical researchers. Previous efforts to improve study recruitment have rarely been informed by theories of human decision making and behavior change. We investigate the trial recruitment strategies reported by study recruiters, guided by two influential theoretical frameworks: shared decision-making (SDM) and the Theoretical Domains Framework (TDF) in order to explore the utility of these frameworks in trial recruitment.

METHODS

We interviewed all nine active study recruiters from a multi-site, open-label pilot trial assessing the feasibility of a large-scale randomized trial. Recruiters were primarily nurses or master's-level research assistants with a range of 3 to 30 years of experience. The semi-structured interviews included questions about the typical recruitment encounter, questions concerning the main components of SDM (e.g. verifying understanding, directive vs. non-directive style), and questions investigating the barriers to and drivers of their recruitment activities, based on the TDF. We used directed content analysis to code quotations into TDF domains, followed by inductive thematic analysis to code quotations into sub-themes within domains and overarching themes across TDF domains. Responses to questions related to SDM were aggregated according to level of endorsement and informed the thematic analysis.

RESULTS

The analysis helped to identify 28 sub-themes across 11 domains. The sub-themes were organized into six overarching themes: coordinating between people, providing guidance to recruiters about challenges, providing resources to recruiters, optimizing study flow, guiding the recruitment decision, and emphasizing the benefits to participation. The SDM analysis revealed recruiters were able to view recruitment interactions as successful even when enrollment did not proceed, and most recruiters took a non-directive (i.e. providing patients with balanced information on available options) or mixed approach over a directive approach (i.e. focus on enrolling patient in study). Most of the core SDM constructs were frequently endorsed.

CONCLUSIONS

Identified sub-themes can be linked to TDF domains for which effective behavior change interventions are known, yielding interventions that can be evaluated as to whether they improve recruitment. Despite having no formal training in shared decision-making, study recruiters reported practices consistent with many elements of SDM. The development of SDM training materials specific to trial recruitment could improve the informed decision-making process for patients.

Using a behavioural approach to explore the factors that affect questionnaire return within a clinical trial: a qualitative study based on the theoretical domains framework

Objectives

To identify barriers and enablers to participant retention in trials requiring questionnaire return using the theoretical domains framework (TDF).

Study design and setting

We identified and subsequently invited participants who did not return at least one questionnaire during their participation in a clinical trial for one-to-one semi-structured telephone interviews. We used a behavioural framework (TDF) to explore whether any of the behavioural domains (eg, beliefs about consequences, emotion) affected questionnaire return. Thereafter, we generated a series of belief statements which summarised the content of participants’ main responses and coded these under separate themes.

Participants

We distributed invites to 279 eligible individuals and subsequently interviewed 9 participants who took part in the C-Gall trial. The C-Gall trial required participants to complete five postal questionnaires during their participation.

Results

Nine participants were interviewed. We developed 7 overarching themes which were relevant for returning postal questionnaires and identified both barriers and enablers from 11 core domains: knowledge; beliefs about consequences; environmental context and resources; reinforcement; emotion; beliefs about capabilities; behavioural regulation; social professional role and identity; skills; intentions and goals. Relevant content coded under these salient domains were categorised into seven key themes: unclear expectations of trial participation, personal attributes for questionnaire return, commitment to returning questionnaires given other priorities, sources of support in returning the questionnaires, individual preferences for presentation mode and timing of the questionnaires, internal and external strategies to encourage questionnaire return and the significance of questionnaire non-return.

Conclusion

We demonstrate how a behavioural approach may be useful for clinical trials associated with significant participation burden (e.g. trials that require multiple questionnaire responses), acting as the essential groundwork for the development of appropriate evidence-based solutions to combat retention issues.

What influences adherence to guidance for postoperative instillation of intravesical chemotherapy to patients with bladder cancer?

OBJECTIVE

To understand the barriers and facilitators to single instillation of intravesical chemotherapy (SI-IVC) use after resection of non-muscle-invasive bladder cancer (NMIBC) in Scotland and England using a behavioural theory-informed approach.

SUBJECTS AND METHODS

In a cross-sectional descriptive study of practices at seven hospitals, we investigated care pathways, policies, and interviewed 30 urology staff responsible for SI-IVC. We used the Theoretical Domains Framework (TDF) to organise our investigation and conducted deductive thematic analyses, while inductively coding emergent beliefs.

RESULTS

Barriers to SI-IVC were present at different organisational levels and professional roles. In four hospitals, there was a policy to not instil SI-IVC in theatre. Six hospitals' staff reported delays in mitomycin C (MMC) ordering and/or local storage. Lack of training, skills and perceived workload affected motivation. Facilitators included access to modern instilling devices (four hospitals) and incorporating reminders in operation proforma (four hospitals). Performance targets (with audit and feedback) within a national governance framework were present in Scotland but not England. Differences in coordinated leadership, sharing best practices, and disliking being perceived as underperforming, were evident in Scotland.

CONCLUSIONS

High-certainty evidence shows that SI-IVC, such as MMC, after NMIBC resection reduces recurrences. This evidence underpins international guidance. The number of eligible patients receiving SI-IVC is variable indicating suboptimal practice. Improving SI-IVC adherence requires modifications to theatre instilling policies, delivery and storage of MMC, staff training, and documentation. Centralising care, with bladder cancer expert leadership and best practices sharing with performance targets, likely led to improvements in Scotland. National quality improvement, incorporating audit and feedback, with additional implementation strategies targeted to professional role could improve adherence and patient outcomes elsewhere. This process should be controlled to clarify implementation intervention effectiveness.

Barriers and enablers of recognition and response to deteriorating patients in the acute hospital setting: A theory-driven interview study using the Theoretical Domains Framework

AIM

To explore barriers and enablers of recognition and response to signs of patient deterioration by nursing staff in an acute hospital.

DESIGN

A theory-driven interview study underpinned by the Theoretical Domains Framework of behaviour change.

METHODS

Between 07/01/2019 and 18/12/2019 a purposive sample of registered nurses and healthcare assistants was recruited to participate in a semi-structured (audio-recorded) interview, to explore the determinants of seven specified behaviours of the afferent limb. Anonymised transcripts were deductively coded (using the 14 Theoretical Domains Framework domains as coding categories) and then extracts within each domain were inductively analysed to synthesise belief statements and themes. Prioritisation criteria from published literature were applied.

RESULTS

Thirty-two semi-structured interviews were conducted. From 1,888 quotes, 184 belief statements and 66 themes were synthesised. One hundred and forty-six belief statements, represented by 58 themes, met prioritisation criteria. Nine domains of the Theoretical Domains Framework were of high importance: Knowledge; Social, Professional Role and Identity; Beliefs about Consequences; Reinforcement; Intentions; Goals; Memory, Attention and Decision Processes; Environment, Context and Resources and Social Influences.

CONCLUSIONS

Barriers and enablers most likely to impact on nursing staff afferent limb behaviour were identified in nine domains of the Theoretical Domains Framework.

Patient and public involvement in numerical aspects of trials: a mixed methods theory-informed survey of trialists' current practices, barriers and facilitators

OBJECTIVE

We aimed to find out if trialists involve patients and the public in numerical aspects of trials, how and what are the barriers and facilitators to doing it.

DESIGN

We developed a survey based on the Theoretical Domains Framework. We used a mixed methods approach to analyse the data and to identify important domains.

SETTING

Online survey targeting UK-based trial units.

PARTICIPANTS

Stakeholders working in UK-based clinical trials, 18 years old or over, understand English and agree to take part in the study.

OUTCOME MEASURES

Trialists' behaviour of involving patients and the public in numerical aspects of trials and its determinants.

RESULTS

We included 187 respondents. Majority were female (70%), trial managers (67%) and involved public and patient partners in numerical aspects of trials (60%). We found lack of knowledge, trialists' perception of public and patient partners' skills, capabilities and motivations, scarce resources, lack of reinforcement, and lack of guidance were barriers to involving public and patient partners in numerical aspects of trials. Positive beliefs about consequences were an incentive to doing it.

CONCLUSIONS

More training, guidance and funding can help trialists involve patient and public partners in numerical aspects, although they were uncertain about public and patient partners' motivation to be involved. Future research should focus on identifying public and patient partners' motivations and develop strategies to improve the communication of numerical aspects.

Why trials lose participants: A multitrial investigation of participants' perspectives using the theoretical domains framework

OBJECTIVES

To use the Theoretical Domains Framework (TDF) to identify barriers and enablers to participant retention in trials requiring questionnaire return and/or attendance at follow-up clinics.

STUDY DESIGN AND SETTING

We invited participants (n = 607) from five pragmatic effectiveness trials, who missed at least one follow-up time point (by not returning a questionnaire and/or not attending a clinic visit), to take part in semistructured telephone interviews. The TDF informed both data collection and analysis. To establish what barriers and enablers most likely influence the target behavior the domain relevance threshold was set at >75% of participants mentioning the domain.

RESULTS

Sixteen participants (out of 25 showing interest) were interviewed. Overall, seven theoretical domains were identified as both barriers and enablers to the target behaviors of attending clinic appointments and returning postal questionnaires. Barriers frequently reported in relation to both target behaviours stemmed from participants' knowledge, beliefs about their capabilities and the consequences of performing (or not performing) the behavior. Two domains were identified as salient for questionnaire return only: goals; and memory, attention and decision-making. Emotion was identified as relevant for clinic attendance only.

CONCLUSION

This is the first study informed by behavioural science to explore trial participants' accounts of trial retention. Findings will serve as a guiding framework when designing trials to limit barriers and enhance enablers of retention within clinical trials.

Investigating the Adoption of Clinical Genomics in Australia. An Implementation Science Case Study

Despite the overwhelming interest in clinical genomics, uptake has been slow. Implementation science offers a systematic approach to reveal pathways to adoption and a theory informed approach to addressing barriers presented. Using case study methodology, we undertook 16 in-depth interviews with nongenetic medical specialists to identify barriers and enablers to the uptake of clinical genomics. Data collection and analysis was guided by two evidence-based behaviour change models: the Theoretical Domains Framework (TDF), and the Capability, Opportunity Motivation Behaviour model (COM-B). Our findings revealed the use of implementation science not only provided a theoretical structure to frame the study but also facilitated uncovering of traditionally difficult to access responses from participants, e.g., “safety in feeling vulnerable” (TDF code emotion/COM-B code motivation). The most challenging phase for participants was ensuring appropriate patients were offered genomic testing. There were several consistent TDF codes: professional identity, social influences, and environmental context and resources and COM-B codes opportunity and motivation, with others varying along the patient journey. We conclude that implementation science methods can maximise the value created by the exploration of factors affecting the uptake of clinical genomics to ensure future interventions are designed to meet the needs of novice nongenetic medical specialists.

Barriers and enablers to source plasma donation by gay, bisexual and other men who have sex with men under revised eligibility criteria: protocol for a multiple stakeholder feasibility study

Background

Blood donation policy in Canada for gay, bisexual and other men who have had sex with men (gbMSM) has changed progressively in the last decade from indefinite deferral to 3-month deferral from last male-to-male sex. Driven by safety data and overseen by the national regulator, more inclusive policies continue to redress the disparity in donation for gbMSM. At the same time, the need for source plasma to prepare fractionated blood products is growing worldwide. The collection and processing of source plasma ensures greater safety compared to whole blood donation with respect to transfusion-transmitted infection. This greater safety offers an opportunity to evolve policies for gbMSM from time-based to behaviour-based deferral using revised eligibility criteria. However, changing policies does not in itself necessarily guarantee that gbMSM will donate or that staff in donor clinics are ready to support them to do so. In anticipation of a move to behaviour-based donation screening for gbMSM in Canada, we aim to assess the acceptability of and perceived barriers and enablers to source plasma donation using revised screening criteria for gbMSM among key stakeholders to inform policy implementation strategies.

Methods

This mixed-methods feasibility study will involve gbMSM and donor centre staff to understand modifiable barriers to implementing more inclusive eligibility criteria. Key informant interviews and surveys will be rooted in the Theoretical Domains Framework to identify modifiable factors associated with source plasma donation motives in gbMSM and training needs in donation centre staff. We will use an integrated knowledge translation approach involving a partnership between researchers, the national blood operator and gbMSM, situating knowledge users as key research team members to ensure their perspectives inform all aspects of the research.

Discussion

Our integrated knowledge translation approach will provide a more comprehensive and collaborative understanding of blood operator and gbMSM needs while accelerating the implementation of study findings. Given the historical backdrop of the decades of exclusion of sexually active gbMSM from blood donation, this study has the potential not only to inform a process and policy for gbMSM to donate source plasma, a blood product, but also offers opportunities for new relationships between these knowledge users.

Defining and assessing context in healthcare implementation studies: a systematic review

BACKGROUND

The implementation of evidence-based healthcare interventions is challenging, with a 17-year gap identified between the generation of evidence and its implementation in routine practice. Although contextual factors such as culture and leadership are strong influences for successful implementation, context remains poorly understood, with a lack of consensus regarding how it should be defined and captured within research. This study addresses this issue by providing insight into how context is defined and assessed within healthcare implementation science literature and develops a definition to enable effective measurement of context.

METHODS

Medline, PsychInfo, CINAHL and EMBASE were searched. Articles were included if studies were empirical and evaluated context during the implementation of a healthcare initiative. These English language articles were published in the previous 10 years and included a definition and assessment of context. Results were synthesised using a narrative approach.

RESULTS

Three thousand and twenty-one search records were obtained of which 64 met the eligibility criteria and were included in the review. Studies used a variety of definitions in terms of the level of detail and explanation provided. Some listed contextual factors (n = 19) while others documented sub-elements of a framework that included context (n = 19). The remaining studies provide a rich definition of general context (n = 11) or aspects of context (n = 15). The Alberta Context Tool was the most frequently used quantitative measure (n = 4), while qualitative papers used a range of frameworks to evaluate context. Mixed methods studies used diverse approaches; some used frameworks to inform the methods chosen while others used quantitative measures to inform qualitative data collection. Most studies (n = 50) applied the chosen measure to all aspects of study design with a majority analysing context at an individual level (n = 29).

CONCLUSIONS

This review highlighted inconsistencies in defining and measuring context which emphasised the need to develop an operational definition. By providing this consensus, improvements in implementation processes may result, as a common understanding will help researchers to appropriately account for context in research.

Barriers to Participation in Therapeutic Clinical Trials as Perceived by Community Oncologists

PURPOSE

Despite considerable research on the barriers to enrollment in cancer therapeutic trials, few studies have elicited barriers from the perspective of community physicians, who provide the majority of cancer care. The purpose of this study was to characterize barriers to and facilitators of cancer therapeutic trials as perceived by oncologists in community practices.

METHODS

Twenty semistructured interviews were conducted with oncologists at six community sites affiliated with City of Hope National Medical Center from March to June 2018. Responses were recorded digitally and transcribed. Data were analyzed using qualitative content analysis.

RESULTS

Of the 20 participants, 4 (20%) were women, 13 (65%) had > 10 years of practice experience, and 16 (80%) reported that < 5% of their patients were enrolled in a therapeutic trial. Participants identified four system-level barriers: lack of appropriate trials for community-based settings, insufficient infrastructure support, restrictive eligibility criteria, and financial limitations; three physician-level barriers: lack of awareness of available trials, lack of knowledge of trial details, and lack of time; and two patient-level barriers: patient burden and negative beliefs/attitudes toward research. Efforts aimed to increase trial availability, clinical trial support personnel, and physician knowledge were identified as major facilitators.

CONCLUSION

Community oncologists face numerous complex, multifaceted barriers to cancer therapeutic trial enrollment. Although expanding clinical research beyond the academic setting allows access to a larger and more diverse patient population, increasing generalizability and relevance of trial findings, there remains a substantial need for new strategies to improve cancer research delivery in the community.

What are potential barriers and enablers to patient and physician participation in Canadian cell therapy trials for stroke? A stakeholder interview study

OBJECTIVES

Early phase cell therapy trials face many barriers to successful, timely completion. To optimise the conduct of a planned clinical trial of mesenchymal stem cell (MSC) therapy for chronic stroke, we sought patient and physician views on possible barriers and enablers that may influence their participation.

DESIGN

Semistructured interview study.

SETTING

Patients were recruited from three rehabilitation centres in Ontario, Canada; physicians were recruited from across Canada through snowball sampling.

PARTICIPANTS

Thirteen chronic stroke patients (patients who had experienced a stroke at least 3 months prior; 10 male, 3 female) and 15 physicians (stroke physiatrists; 9 male, 6 female) participated in our interview study. Data adequacy was reached after 13 patient interviews and 13 physician interviews.

METHODS

Interview guides and directed content analysis were based on the Theoretical Domains Framework (TDF). Interviews were coded, and relevant themes were identified.

RESULTS

Most patients were optimistic about participating in an MSC therapy clinical trial, and many expressed interest in participating, even if it was a randomised controlled trial with the possibility of being allocated to a placebo group. However, the method of administration of cells (intravascular preferred to intracerebral) and goal of the trial (efficacy preferred to safety) may influence their intention to participate. All physicians expressed interest in screening for the trial, though many stated they were less motivated to contribute to a safety trial. Physicians also identified several time-related barriers and the need for resources to ensure feasibility.

CONCLUSIONS

This novel application of the TDF helped identify key potential barriers and enablers prior to conducting a clinical trial of MSC therapy for stroke. This will be used to refine the design and conduct of our trial. A similar approach may be adopted by other investigators considering early phase cell therapy trials.

Understanding factors influencing venous leg ulcer guideline implementation in Australian primary care

The aim of this study was to gain a better understanding of the venous leg ulcer (VLU) management in primary health care settings located in Melbourne metropolitan and rural Victoria, Australia. We explored health professionals' perspective on the use of the Australian and New Zealand Venous Leg Ulcer Clinical Practice Guideline (VLU CPG) to identify the main challenges of VLU CPG uptake in clinical practice. We conducted semi-structured interviews with 15 general practitioners (GPs) and 20 practice nurses (PNs), including two Aboriginal health nurses. The Theoretical Domains Framework guided data collection and analysis. Data were analysed using a theory-driven analysis. We found a lack of awareness of the VLU CPGs, which resulted in suboptimal knowledge and limited adherence to evidence-based recommendations. Environmental factors, such as busy nature of clinical environment and absence of handheld Doppler ultrasound, as well as social and professional identity factors, such as reliance on previous experience and colleague's advice, influenced the uptake of the VLU CPGs in primary care. Findings of this study will inform development of interventions to increase the uptake of the VLU CPG in primary care settings and to reduce the evidence-practice gap in VLU management by health professionals.

Major Outcomes With Personalized Dialysate TEMPerature (MyTEMP): Rationale and Design of a Pragmatic, Registry-Based, Cluster Randomized Controlled Trial

BACKGROUND

Small randomized trials demonstrated that a lower compared with higher dialysate temperature reduced the average drop in intradialytic blood pressure. Some observational studies demonstrated that a lower compared with higher dialysate temperature was associated with a lower risk of all-cause mortality and cardiovascular mortality. There is now the need for a large randomized trial that compares the effect of a low vs high dialysate temperature on major cardiovascular outcomes.

OBJECTIVE

The purpose of this study is to test the effect of outpatient hemodialysis centers randomized to (1) a personalized temperature-reduced dialysate protocol or (2) a standard-temperature dialysate protocol for 4 years on cardiovascular-related death and hospitalizations.

DESIGN

The design of the study is a pragmatic, registry-based, open-label, cluster randomized controlled trial.

SETTING

Hemodialysis centers in Ontario, Canada, were randomized on February 1, 2017, for a trial start date of April 3, 2017, and end date of March 31, 2021.

PARTICIPANTS

In total, 84 hemodialysis centers will care for approximately 15 500 patients and provide over 4 million dialysis sessions over a 4-year follow-up.

INTERVENTION

Hemodialysis centers were randomized (1:1) to provide (1) a personalized temperature-reduced dialysate protocol or (2) a standard-temperature dialysate protocol of 36.5°C. For the personalized protocol, nurses set the dialysate temperature between 0.5°C and 0.9°C below the patient's predialysis body temperature for each dialysis session, to a minimum dialysate temperature of 35.5°C.

PRIMARY OUTCOME

A composite of cardiovascular-related death or major cardiovascular-related hospitalization (a hospital admission with myocardial infarction, congestive heart failure, or ischemic stroke) captured in Ontario health care administrative databases.

PLANNED PRIMARY ANALYSIS

The primary analysis will follow an intent-to-treat approach. The hazard ratio of time-to-first event will be estimated from a Cox model. Within-center correlation will be considered using a robust sandwich estimator. Observation time will be censored on the trial end date or when patients die from a noncardiovascular event.

Exploring the experiences and perspectives of substitute decision-makers involved in decisions about deceased organ donation: a qualitative study protocol

INTRODUCTION

In Canada, deceased organ donation provides over 80% of transplanted organs. At the time of death, families, friends or others assume responsibility as substitute decision-makers (SDMs) to consent to organ donation. Despite their central role in this process, little is known about what barriers, enablers and beliefs influence decision-making among SDMs. This study aims to explore the experiences and perspectives of SDMs involved in making decisions around the withdrawal of life-sustaining therapies, end-of-life care and deceased organ donation.

METHODS AND ANALYSIS

SDMs of 60 patients admitted to intensive care units will be enrolled for this study. Ten hospitals across five provinces in Canada in a prospective multicentre qualitative cohort study. We will conduct semistructured telephone interviews in English or French with SDMs between 6 and 8 weeks after the patient's death. Our sampling frame will stratify SDMs into three groups: SDMs who were not approached for organ donation; SDMs who were approached and consented to donate and SDMs who were approached but did not consent to donate. We will use two complementary theoretical frameworks-the Common-Sense Self-Regulation Model and the Theoretical Domains Framework- to inform our interview guide. Interview data will be analysed using deductive directed content analysis and inductive thematic analysis.

ETHICS AND DISSEMINATION

This study has been approved by the Centre Hospitalier de l'Université de Montréal Research Ethics Board. The findings from this study will help identify key factors affecting substitute decision-making in deceased organ donation, reasons for non-consent and barriers to achieve congruency between SDM and patient wishes. Ultimately, these data will contribute to the development and evaluation of tools and training for healthcare providers to support SDMs in making decisions about organ donation.

How actionable are staff behaviours specified in policy documents? A document analysis of protocols for managing deteriorating patients

BACKGROUND

To optimise care of deteriorating patients, healthcare organisations have implemented rapid response systems including an "afferent" and "efferent" limb. Afferent limb behaviours include monitoring vital signs and escalating care. To strengthen afferent limb behaviour and reduce adverse patient outcomes, the National Early Warning Score was implemented in the UK. There are no published reports of how National Early Warning Score guidance has translated into trust-level deteriorating patient policy and whether these documents provide clear, actionable statements guiding staff.

AIM

To identify how deteriorating patient policy documents provide "actionable" behavioural instruction for staff, responsible for actioning the afferent limb of the rapid response system.

DESIGN

A structured content analysis of a national guideline and local policies using a behaviour specification framework.

METHODS

Local deteriorating patient policies were obtained. Statements of behaviour were extracted from policies; coded using a behaviour specification framework: Target, Action, Context, Timing and Actor and scored for specificity (1 = present, nonspecific; 2 = present, specific). Frequencies and proportions of statements containing elements of the Target, Action, Context, Timing and Actor framework were summarised descriptively. Reporting was guided by the COREQ checklist.

RESULTS

There were more statements related to monitoring than escalation behaviour (65% vs 35%). Despite high levels of clear specification of the action (94%) and the target of the behaviour (74%), context, timing and actor were poorly specified (37%, 37% and 33%).

CONCLUSION

Delay in escalating deteriorating patients is associated with adverse outcomes. Some delay could be addressed by writing local protocols with greater behavioural specificity, to facilitate actionability.

RELEVANCE TO CLINICAL PRACTICE

Numerous clinical staff are required for an effective response to patient deterioration. To mitigate role confusion, local policy writers should provide clear specification of the actor. As the behaviours are time-sensitive, clear specification of the time frame may increase actionability of policy statements for clinical staff.

Dialysate temperature reduction for intradialytic hypotension for people with chronic kidney disease requiring haemodialysis

BACKGROUND

Intradialytic hypotension (IDH) is a common complication of haemodialysis (HD), and a risk factor of cardiovascular morbidity and death. Several clinical studies suggested that reduction of dialysate temperature, such as fixed reduction of dialysate temperature or isothermal dialysate using a biofeedback system, might improve the IDH rate.

OBJECTIVES

This review aimed to evaluate the benefits and harms of dialysate temperature reduction for IDH among patients with chronic kidney disease requiring HD, compared with standard dialysate temperature.

SEARCH METHODS

We searched Cochrane Kidney and Transplant's Specialised Register up to 14 May 2019 through contact with the Information Specialist using search terms relevant to this review. Studies in the Register are identified through searches of CENTRAL, MEDLINE, EMBASE, conference proceedings, the International Clinical Trials Register (ICTRP) Search Portal, and ClinicalTrials.gov.

SELECTION CRITERIA

All randomised controlled trials (RCTs), cross-over RCTs, cluster RCTs and quasi-RCTs were included in the review.

DATA COLLECTION AND ANALYSIS

Two authors independently extracted information including participants, interventions, outcomes, methods of the study, and risks of bias. We used a random-effects model to perform quantitative synthesis of the evidence. We assessed the risks of bias for each study using the Cochrane 'Risk of bias' tool. We assessed the certainty of evidence using Grades of Recommendation, Assessment, Development and Evaluation (GRADE).

MAIN RESULTS

We included 25 studies (712 participants). Three studies were parallel RCTs and the others were cross-over RCTs. Nineteen studies compared fixed reduction of dialysate temperature (below 36°C) and standard dialysate temperature (37°C to 37.5°C). Most studies were of unclear or high risk of bias. Compared with standard dialysate, it is uncertain whether fixed reduction of dialysate temperature improves IDH rate (8 studies, 153 participants: rate ratio 0.52, 95% CI 0.34 to 0.80; very low certainty evidence); however, it might increase the discomfort rate compared with standard dialysate (4 studies, 161 participants: rate ratio 8.31, 95% CI 1.86 to 37.12; very low certainty evidence). There were no reported dropouts due to adverse events. No study reported death, acute coronary syndrome or stroke.Three studies compared isothermal dialysate and thermoneutral dialysate. Isothermal dialysate might improve the IDH rate compared with thermoneutral dialysate (2 studies, 133 participants: rate ratio 0.68, 95% CI 0.60 to 0.76; I² = 0%; very low certainty evidence). There were no reports of discomfort rate (1 study) or dropouts due to adverse events (2 studies). No study reported death, acute coronary syndrome or stroke.

AUTHORS' CONCLUSIONS

Reduction of dialysate temperature may prevent IDH, but the conclusion is uncertain. Larger studies that measure important outcomes for HD patients are required to assess the effect of reduction of dialysate temperature. Six ongoing studies may provide much-needed high quality evidence in the future.

So You Want to Give Stem Cells to Babies? Neonatologists and Parents' Views to Optimize Clinical Trials

OBJECTIVE

To identify barriers and enablers that may influence parents' and neonatologists' participation in clinical trials of mesenchymal stromal cells for bronchopulmonary dysplasia.

STUDY DESIGN

This qualitative study involved one-on-one semistructured interviews with parents of extremely preterm infants (n = 18) and neonatologists (n = 16). Interview guides and directed content analysis were framed using the theoretical domains framework, a tool specifically developed for implementation research to identify influences on behavior.

RESULTS

Key barriers for parents included their lack of knowledge about clinical trial processes in general, stem cells, and concerns about their risks and side effects. Importantly, parents preferred to be approached for recruitment directly by a neonatologist, either before delivery or 1 or 2 weeks after birth. However, the majority of neonatologists felt that approaching parents was not part of their role. Neonatologists reported competing priorities, time commitment, costs, and lack of institutional support as significant barriers to their ability to recruit patients.

CONCLUSIONS

By integrating stakeholders early into the development of a clinical trial of mesenchymal stromal cell therapy, we identified and can address important barriers to enrollment. Some identified barriers were unanticipated and could have compromised recruitment had they not been identified by this study. We suggest that this approach can be used more broadly for other early phase clinical trials in pediatrics.

Anesthesiology Control Tower-Feasibility Assessment to Support Translation (ACTFAST): Mixed-Methods Study of a Novel Telemedicine-Based Support System for the Operating Room

Background

Despite efforts to improve patient outcomes, major morbidity and mortality remain common after surgery. Health information technologies that provide decision support for clinicians might improve perioperative and postoperative patient care. Evaluating the usability of these technologies and barriers to their implementation can facilitate their acceptance within health systems.

Objective

This manuscript describes usability testing and refinement of an innovative telemedicine-based clinical support system, the Anesthesiology Control Tower (ACT). It also reports stakeholders’ perceptions of the barriers and facilitators to implementation of the intervention.

Methods

Three phases of testing were conducted in an iterative manner. Phase 1 testing employed a think-aloud protocol analysis to identify surface-level usability problems with individual software components of the ACT and its structure. Phase 2 testing involved an extended qualitative and quantitative real-world usability analysis. Phase 3 sought to identify major barriers and facilitators to implementation of the ACT through semistructured interviews with key stakeholders.

Results

Phase 1 and phase 2 usability testing sessions identified numerous usability problems with the software components of the ACT. The ACT platform was revised in seven iterations in response to these usability concerns. Initial satisfaction with the ACT, as measured by standardized instruments, was below commonly accepted cutoffs for these measures. Satisfaction improved to acceptable levels over the course of revision and testing. A number of barriers to implementation were also identified and addressed during the refinement of the ACT intervention.

Conclusions

The ACT model can improve the standard of perioperative anesthesia care. Through our thorough and iterative usability testing process and stakeholder assessment of barriers and facilitators, we enhanced the acceptability of this novel technology and improved our ability to implement this innovation into routine practice.

Mālama nā makua i nā keiki me ka hānō: Native Hawaiian Parents Caring for Their Children with Asthma (Part 2)

Objective: Native Hawaiian children have the highest prevalence of asthma among all ethnicities in Hawai'i. Mālama Part 2 describes continuing research, exploring contemporary native Hawaiian parents' perspective, and experience of caring for their children with asthma in the context of uncertainty while living on the islands of Hawai'i, Kaua'i, Maui, Moloka'i and Lāna'i. Design: Descriptive qualitative approach by means of directed content analysis using focus groups was applied to this study. Eight open-ended questions elicited asthma history, asthma management, and how the Hawaiian culture affects parents' health practices. Directed content analysis applied Mishel's Uncertainty in Illness Theory (UIT) to guide data collection, organization, and analysis. Sample: Thirty-three native Hawaiian parents with a child with asthma met in 9 separate focus groups during 2012-2015 on the islands of Hawai'i, Kaua'i, Maui, Moloka'i, and Lāna'i. Results: The study's findings were congruent with the first Mālama study results of focus groups on O'ahu. Contextual influences including indigenous worldview, cultural values, history, and assimilation and acculturation factors affected native Hawaiian parents' perceptions and experiences with conventional asthma care. Moreover, Hawaiian parents living on islands outside of metropolitan O'ahu reported geographic barriers that contributed to their uncertainty. Conclusion: Political action is required for comprehensive medical care, health education, and nursing services to be delivered to families living on all islands. Integrating Hawaiian cultural values, involving 'ohana, and applying complementary alternative therapies as well as standard asthma management will strongly support native Hawaiian parents caring for their children with asthma.

Leveraging pragmatic clinical trial design to advance phosphate management in end-stage renal disease

PURPOSE OF REVIEW

Phosphate lowering toward the normal range is advocated and widely practiced in patients with end-stage renal disease receiving dialysis. This approach is guided by basic science data and large observational studies that have demonstrated a consistent association between hyperphosphatemia and adverse events, including cardiovascular morbidity and all-cause mortality. There has never been a clinical trial to assess the efficacy of phosphate lowering in maintenance dialysis recipients.

RECENT FINDINGS

Despite several trials comparing the effect of different phosphate-binding agents on biochemical targets, no trial has evaluated whether targeting normophosphatemia using phosphate binders mediates better patient outcomes. Recent work has highlighted the feasibility of conducting a randomized trial comparing two strategies for phosphate control. We believe that this research question is optimally suited to a pragmatic trial design.

SUMMARY

There is a pressing need for a well-designed randomized controlled trial to evaluate whether intensive phosphate lowering confers improved cardiovascular outcomes in patients receiving maintenance dialysis. We propose a broad framework for such a trial using the principles of pragmatic trial design. The ultimate objective of such a trial will be to provide patients and clinicians with reliable and broadly applicable information on whether reducing serum phosphate toward the normal range improves patient-important outcomes.

Improving the sustainability of hospital-based interventions: a study protocol for a systematic review

INTRODUCTION

Sustaining effective interventions in hospital environments is essential to improving health outcomes, and reducing research waste. Current evidence suggests many interventions are not sustained beyond their initial delivery. The reason for this failure remains unclear. Increasingly research is employing theoretical frameworks and models to identify critical factors that influence the implementation of interventions. However, little is known about the value of these frameworks on sustainability. The aim of this review is to examine the evidence regarding the use of theoretical frameworks to maximise effective intervention sustainability in hospital-based settings in order to better understand their role in supporting long-term intervention use.

METHODS AND ANALYSIS

Systematic review. We will systematically search the following databases: Medline, AMED, CINAHL, Embase and Cochrane Library (CENTRAL, CDSR, DARE, HTA). We will also hand search relevant journals and will check the bibliographies of all included studies. Language and date limitations will be applied. We will include empirical studies that have used a theoretical framework (or model) and have explicitly reported the sustainability of an intervention (or programme). One reviewer will remove obviously irrelevant titles. The remaining abstracts and full-text articles will be screened by two independent reviewers to determine their eligibility for inclusion. Disagreements will be resolved by discussion, and may involve a third reviewer if required. Key study characteristics will be extracted (study design, population demographics, setting, evidence of sustained change, use of theoretical frameworks and any barriers or facilitators data reported) by one reviewer and cross-checked by another reviewer. Descriptive data will be tabulated within evidence tables, and key findings will be brought together within a narrative synthesis.

ETHICS AND DISSEMINATION

Formal ethical approval is not required as no primary data will be collected. Dissemination of results will be through peer-reviewed journal publications, presentation at an international conference and social media.

Developing Behavior Change Interventions for Self-Management in Chronic Illness: An Integrative Overview

More people than ever are living longer with chronic conditions such as obesity, type 2 diabetes, and heart disease. Behavior change for effective self-management can improve health outcomes and quality of life in people living with such chronic illnesses. The science of developing behavior change interventions with impact for patients aims to optimize the reach, effectiveness, adoption, implementation, and maintenance of interventions and rigorous evaluation of outcomes and processes of behavior change. The development of new services and technologies offers opportunities to enhance the scope of delivery of interventions to support behavior change and self-management at scale. Herein, we review key contemporary approaches to intervention development, provide a critical overview, and integrate these approaches into a pragmatic, user-friendly framework to rigorously guide decision-making in behavior change intervention development. Moreover, we highlight novel emerging methods for rapid and agile intervention development. On-going progress in the science of intervention development is needed to remain in step with such new developments and to continue to leverage behavioral science's capacity to contribute to optimizing interventions, modify behavior, and facilitate self-management in individuals living with chronic illness.

Barriers and Facilitators to Self-Directed Learning in Continuing Professional Development for Physicians in Canada: A Scoping Review

PURPOSE

This scoping review explored the barriers and facilitators that influence engagement in and implementation of self-directed learning (SDL) in continuing professional development (CPD) for physicians in Canada.

METHOD

This review followed the six-stage scoping review framework of Arksey and O'Malley and of Daudt et al. In 2015, the authors searched eight online databases for English-language Canadian articles published January 2005-December 2015. To chart and analyze data from the 17 included studies, they employed a two-step analysis process composed of conventional content analysis followed by directed coding applying the Theoretical Domains Framework (TDF).

RESULTS

Conventional content analysis generated five categories of barriers and facilitators: individual, program, technological, environmental, and workplace/organizational. Directed coding guided by the TDF allowed analysis of barriers and facilitators to behavior change according to two key groups: physicians engaging in SDL, and SDL developers designing and implementing SDL programs. Of the 318 total barriers and facilitators coded, 290 (91.2%) were coded for physicians and 28 (8.8%) for SDL developers. The majority (209; 65.7%) were coded in four key TDF domains: environmental context and resources, social influences, beliefs about consequences, and behavioral regulation.

CONCLUSIONS

This scoping review identified five categories of barriers and facilitators in the literature and four key TDF domains where most factors related to behavior change of physicians and SDL developers regarding SDL programs in CPD were coded. There was a significant gap in the literature about factors that may contribute to SDL developers' capacity to design and implement SDL programs in CPD.

Barriers and Enablers to Organ Donation After Circulatory Determination of Death: A Qualitative Study Exploring the Beliefs of Frontline Intensive Care Unit Professionals and Organ Donor Coordinators

Background

A shortage of transplantable organs is a global problem. The purpose of this study was to explore frontline intensive care unit professionals' and organ donor coordinators' perceptions and beliefs around the process of, and the barriers and enablers to, donation after circulatory determination death (DCDD).

Methods

This qualitative descriptive study used a semistructured interview guide informed by the Theoretical Domains Framework to interview 55 key informants (physicians, nurses, and organ donation coordinators) in intensive care units (hospitals) and organ donation organizations across Canada.

Results

Interviews were analyzed using a 6-step systematic approach: coding, generation of specific beliefs, identification of themes, aggregation of themes into categories, assignment of barrier or enabler and analysis for shared and unique discipline barriers and enablers. Seven broad categories encompassing 29 themes of barriers (n = 21) and enablers (n = 4) to DCDD use were identified; n = 4 (14%) themes were conflicting, acting as barriers and enablers. Most themes (n = 26) were shared across the 3 key informant groups while n = 3 themes were unique to physicians. The top 3 shared barriers were: (1) DCDD education is needed for healthcare professionals, (2) a standardized and systematic screening process to identify potential DCDD donors is needed, and (3) practice variation across regions with respect to communication about DCDD with families. A limited number of differences were found by region.

Conclusions

Multiple barriers and enablers to DCDD use were identified. These beliefs identify potential individual, team, organization, and system targets for behavior change interventions to increase DCDD rates which, in turn, should lead to more transplantation, reducing patient morbidity and mortality at a population level.
