The effectiveness of a de-implementation strategy to reduce low-value blood management techniques in primary hip and knee arthroplasty: a pragmatic cluster-randomized controlled trial

Impact of consensus guideline publication on the timing of elective pediatric umbilical hernia repair

BACKGROUND

The American Academy of Pediatrics published consensus guidelines advising observation of asymptomatic umbilical hernias until age 4 or 5, given unnecessary risks of early intervention and substantial practice variation. Yet, the impact of guidelines on early repair (age <4) or if certain groups remain at risk for avoidable intervention is unclear.

METHODS

This retrospective study used data from children's hospitals participating in the Pediatric Health Information System database. Children aged 17 years and younger who underwent umbilical hernia repair from July 2017 to August 2022 were eligible for inclusion. Children with recurrent hernias, an emergency, or urgent presentation were excluded. An interrupted time series using segmented multivariable logistic regression estimated the association of guideline publication in November 2019 with the odds of guideline-adherent repair (age ≥4) after adjusting for sociodemographic characteristics and hospital-level random effects.

RESULTS

16,544 children underwent repair, of which 3,115 (18.8%) were children <4 years old. After adjustment, guideline publication was associated with an immediate increase in guideline-adherent repairs (odds ratio = 1.25 95% confidence interval = 1.05-1.49). The interrupted time series found that each month after publication was associated with a 2% increase in the odds of guideline-adherent repair (odds ratio = 1.02, 95% confidence interval = 1.01-1.03). Children with public insurance were nearly 20% less likely to receive guideline-adherent repair than privately insured children (odds ratio = 0.82, 95% confidence interval = 0.74-0.91). Children in the Midwest had lower odds of guideline-adherent repair (Midwest versus Northeast: odds ratio = 0.45. 95% confidence interval = 0.24-0.84).

CONCLUSION

Guideline publication was associated with greater odds of guideline-adherent repair, yet public insurance coverage and Midwest location remain significant predictors of early repair against recommendations.

Intraoperative use of balanced crystalloids versus 0.9% saline: a systematic review and meta-analysis of randomised controlled studies

BACKGROUND

The evidence regarding optimal crystalloid use in the perioperative period remains unclear. As the primary aim of this study, we sought to summarise the data from RCTs examining whether use of balanced crystalloids compared with 0.9% saline (saline) leads to differences in patient-important outcomes.

METHODS

We searched Ovid MEDLINE, Embase, the Cochrane library, and Clinicaltrials.gov, from inception until December 15, 2022, and included RCTs that intraoperatively randomised adult participants to receive either balanced fluids or saline. We pooled data using a random-effects model and present risk ratios (RRs) or mean differences (MDs), along with 95% confidence intervals (CIs). We assessed individual study risk of bias using the modified Cochrane tool, and certainty of evidence using GRADE.

RESULTS

Of 5959 citations, we included 38 RCTs (n=3776 patients). Pooled analysis showed that intraoperative use of balanced fluids compared with saline had an uncertain effect on postoperative mortality analysed at the longest point of follow-up (RR 1.51, 95% CI: 0.42-5.36) and postoperative need for renal replacement therapy (RR 0.95, 95% CI: 0.56-1.59), both very low certainty. Furthermore, use of balanced crystalloids probably leads to a higher postoperative serum pH (MD 0.05, 95% CI: 0.04-0.06), moderate certainty.

CONCLUSIONS

Use of balanced crystalloids, compared with saline, in the perioperative setting has an uncertain effect on mortality and need for renal replacement therapy but probably improves postoperative acid-base status. Further research is needed to determine whether balanced crystalloid use affects patient-important outcomes.

Has the Use of Electrodiagnostic Studies for Carpal Tunnel Syndrome Changed After the 2016 American Academy of Orthopaedic Surgeons Clinical Practice Guideline?

PURPOSE

A 2016 American Academy of Orthopaedic Surgeons (AAOS) clinical practice guideline (CPG) de-emphasized the need for electrodiagnostic studies (EDS) for carpal tunnel syndrome (CTS). We tested the hypothesis that use of EDS decreased after the AAOS CPG.

METHODS

Using a national administrative claims database, we measured the proportion of patients with a diagnosis of CTS who underwent EDS within 1 year after diagnosis between 2011 and 2019. Using an interrupted time series design, we defined 2 time periods (pre-CPG and post-CPG) and compared EDS usage between the periods using segmented regression analysis. We conducted a subgroup analysis of preoperative EDS usage in patients who underwent carpal tunnel release.

RESULTS

Of 2,081,829 patients with CTS, 315,449 (15.2%) underwent EDS within 1 year after diagnosis. The segmented regression analysis showed a decrease in the level of EDS usage after publication of the AAOS CPG (-11.50 per 1,000 patients [95% CI, -1.47 to -0.95 per 1,000 patients]); however, the rate of EDS usage increased in the post-CPG period (+1.75 per 1,000 patients per quarter [95% CI, 0.97-2.54 per 1,000 patients per quarter]). Of 473,753 eligible patients who underwent carpal tunnel release, 139,186 (29.4%) underwent EDS within 6 months before surgery. After publication of the AAOS CPG, preoperative EDS usage decreased by -23.57 per 1,000 patients (95% CI, -37.72 to -9.42 per 1,000 patients). However, these decreasing trends in EDS usage predated the 2016 AAOS CPG.

CONCLUSIONS

The overall and preoperative EDS usage for CTS has been decreasing since at least 2014, predating the 2016 AAOS CPG, reflecting the rapid implementation of evidence into practice. However, EDS usage has increased in the post-CPG period, and a considerable proportion of patients who underwent carpal tunnel release still received EDS.

CLINICAL RELEVANCE

Given its high costs and disputed value, routine EDS usage should be considered for further deimplementation initiatives.

Strategies for de-implementation of low-value care-a scoping review

BACKGROUND

The use of low-value care (LVC) is a persistent problem that calls for knowledge about strategies for de-implementation. However, studies are dispersed across many clinical fields, and there is no overview of strategies that can be used to support the de-implementation of LVC. The extent to which strategies used for implementation are also used in de-implementing LVC is unknown. The aim of this scoping review is to (1) identify strategies for the de-implementation of LVC described in the scientific literature and (2) compare de-implementation strategies to implementation strategies as specified in the Expert Recommendation for Implementing Change (ERIC) and strategies added by Perry et al. METHOD: A scoping review was conducted according to recommendations outlined by Arksey and O'Malley. Four scientific databases were searched, relevant articles were snowball searched, and the journal Implementation Science was searched manually for peer-reviewed journal articles in English. Articles were included if they were empirical studies of strategies designed to reduce the use of LVC. Two reviewers conducted all abstract and full-text reviews, and conflicting decisions were discussed until consensus was reached. Data were charted using a piloted data-charting form. The strategies were first coded inductively and then mapped onto the ERIC compilation of implementation strategies.

RESULTS

The scoping review identified a total of 71 unique de-implementation strategies described in the literature. Of these, 62 strategies could be mapped onto ERIC strategies, and four strategies onto one added category. Half (50%) of the 73 ERIC implementation strategies were used for de-implementation purposes. Five identified de-implementation strategies could not be mapped onto any of the existing strategies in ERIC.

CONCLUSIONS

Similar strategies are used for de-implementation and implementation. However, only a half of the implementation strategies included in the ERIC compilation were represented in the de-implementation studies, which may imply that some strategies are being underused or that they are not applicable for de-implementation purposes. The strategies assess and redesign workflow (a strategy previously suggested to be added to ERIC), accountability tool, and communication tool (unique new strategies for de-implementation) could complement the existing ERIC compilation when used for de-implementation purposes.

Neurodevelopmental Therapy for Cerebral Palsy: A Meta-analysis

BACKGROUND AND OBJECTIVE

Bobath therapy, or neurodevelopmental therapy (NDT) is widely practiced despite evidence other interventions are more effective in cerebral palsy (CP). The objective is to determine the efficacy of NDT in children and infants with CP or high risk of CP.

METHODS

Cumulative Index to Nursing and Allied Health Literature, Cochrane Library, Embase, and Medline were searched through March 2021. Randomized controlled trials comparing NDT with any or no intervention were included. Meta-analysis was conducted with standardized mean differences calculated. Quality was assessed by using Cochrane Risk of Bias tool-2 and certainty by using Grading of Recommendations Assessment, Development, and Evaluation.

RESULTS

Of 667 records screened, 34 studies (in 35 publications, 1332 participants) met inclusion. Four meta-analyses were conducted assessing motor function. We found no effect between NDT and control (pooled effect size 0.13 [-0.20 to 0.46]), a moderate effect favoring activity-based approaches (0.76 [0.12 to 1.40]) and body function and structures (0.77 [0.19 to 1.35]) over NDT and no effect between higher- and lower-dose NDT (0.32 [-0.11 to 0.75]). A strong recommendation against the use of NDT at any dose was made. Studies were not all Consolidated Standards of Reporting Trials-compliant. NDT versus activity-based comparator had considerable heterogeneity (I2 = 80%) reflecting varied measures.

CONCLUSIONS

We found that activity-based and body structure and function interventions are more effective than NDT for improving motor function, NDT is no more effective than control, and higher-dose NDT is not more effective than lower-dose. Deimplementation of NDT in CP is required.

Determinants of the de-implementation of low-value care: a multi-method study

Background

There is an urgent need to understand the determinants (i.e., barriers and facilitators) of de-implementation. The purpose of this study was to develop a comprehensive list of determinants of the de-implementation of low-value care from the published literature and to compare this list to determinants identified by a group of stakeholders with lived experience with de-implementation.

Methods

This was a two-phase multi-method study. First, a systematic review examined published barriers and facilitators to de-implementation. Articles were identified through searches within electronic databases, reference lists and the grey literature. Citations were screened independently and in duplicate and included if they were: 1) written in English; and 2) described a barrier or facilitator to de-implementation of any clinical practice in adults (age ≥ 18 years). ‘Raw text’ determinants cited within included articles were extracted and synthesized into a list of representative determinants using conventional content analysis. Second, semi-structured interviews were conducted with decision-makers (unit managers and medical directors) and healthcare professionals working in adult critical care medicine to explore the overlap between the determinants found in the systematic review to those experienced in critical care medicine. Thematic content analysis was used to identify key themes emerging from the interviews.

Results

In the systematic review, reviewers included 172 articles from 35,368 unique citations. From 437 raw text barriers and 280 raw text facilitators, content analysis produced 29 distinct barriers and 24 distinct facilitators to de-implementation. Distinct barriers commonly cited within raw text included ‘lack of credible evidence to support de-implementation’ (n = 90, 21%), ‘entrenched norms and clinicians’ resistance to change (n = 43, 21%), and ‘patient demands and preferences’ (n = 28, 6%). Distinct facilitators commonly cited within raw text included ‘stakeholder collaboration and communication’ (n = 43, 15%), and ‘availability of credible evidence’ (n = 33, 12%). From stakeholder interviews, 23 of 29 distinct barriers and 20 of 24 distinct facilitators from the systematic review were cited as key themes relevant to de-implementation in critical care.

Conclusions

The availability and quality of evidence that identifies a clinical practice as low-value, as well as healthcare professional willingness to change, and stakeholder collaboration are common and important determinants of de-implementation and may serve as targets for future de-implementation initiatives.

Trial registration

The systematic review was registered in PROSPERO CRD42016050234.

Using theories and frameworks to understand how to reduce low-value healthcare: a scoping review

BACKGROUND

There is recognition that the overuse of procedures, testing, and medications constitutes low-value care which strains the healthcare system and, in some circumstances, can cause unnecessary stress and harm for patients. Initiatives across dozens of countries have raised awareness about the harms of low-value care but have had mixed success and the levels of reductions realized have been modest. Similar to the complex drivers of implementation processes, there is a limited understanding of the individual and social behavioral aspects of de-implementation. While researchers have begun to use theory to elucidate the dynamics of de-implementation, the research remains largely atheoretical. The use of theory supports the understanding of how and why interventions succeed or fail and what key factors predict success. The purpose of this scoping review was to identify and characterize the use of theoretical approaches used to understand and/or explain what influences efforts to reduce low-value care.

METHODS

We conducted a review of MEDLINE, EMBASE, CINAHL, and Scopus databases from inception to June 2021. Building on previous research, 43 key terms were used to search the literature. The database searches identified 1998 unique articles for which titles and abstracts were screened for inclusion; 232 items were selected for full-text review.

RESULTS

Forty-eight studies met the inclusion criteria. Over half of the included articles were published in the last 2 years. The Theoretical Domains Framework (TDF) was the most commonly used determinant framework (n = 22). Of studies that used classic theories, the majority used the Theory of Planned Behavior (n = 6). For implementation theories, Normalization Process Theory and COM-B were used (n = 7). Theories or frameworks were used primarily to identify determinants (n = 37) and inform data analysis (n = 31). Eleven types of low-value care were examined in the included studies, with prescribing practices (e.g., overuse, polypharmacy, and appropriate prescribing) targeted most frequently.

CONCLUSIONS

This scoping review provides a rigorous, comprehensive, and extensive synthesis of theoretical approaches used to understand and/or explain what factors influence efforts to reduce low-value care. The results of this review can provide direction and insight for future primary research to support de-implementation and the reduction of low-value care.

A tailored intervention does not reduce low value MRI's and arthroscopies in degenerative knee disease when the secular time trend is taken into account: a difference-in-difference analysis

PURPOSE

To evaluate the effectiveness of a tailored intervention to reduce low value MRIs and arthroscopies among patients ≥ 50 years with degenerative knee disease in 13 Dutch orthopaedic centers (intervention group) compared with all other Dutch orthopaedic centers (control group).

METHODS

All patients with degenerative knee disease ≥ 50 years admitted to Dutch orthopaedic centers from January 2016 to December 2018 were included. The tailored intervention included participation of clinical champions, education on the Dutch Choosing Wisely recommendation for MRI's and arthroscopies in degenerative knee disease, training of orthopaedic surgeons to manage patient expectations, performance feedback, and provision of a patient brochure. A difference-in-difference analysis was used to compare the time trend before (admitted January 2016-June 2017) and after introduction of the intervention (July 2017-December 2018) between intervention and control hospitals. Primary outcome was the monthly percentage of patients receiving a MRI or knee arthroscopy, weighted by type of hospital.

RESULTS

136,446 patients were included, of whom 32,163 were treated in the intervention hospitals. The weighted percentage of patients receiving a MRI on average declined by 0.15% per month (β =  - 0.15, P < 0.001) and by 0.19% per month for arthroscopy (β =  - 0.19, P < 0.001). However, these changes over time did not differ between intervention and control hospitals, neither for MRI (β =  - 0.74, P = 0.228) nor arthroscopy (β = 0.13, P = 0.688).

CONCLUSIONS

The extent to which patients ≥ 50 years with degenerative knee disease received a MRI or arthroscopy declined significantly over time, but could not be attributed to the tailored intervention. This secular downward time trend may reflect anoverall focus of reducing low value care in The Netherlands.

Transfusion thresholds for guiding red blood cell transfusion

BACKGROUND

The optimal haemoglobin threshold for use of red blood cell (RBC) transfusions in anaemic patients remains an active field of research. Blood is a scarce resource, and in some countries, transfusions are less safe than in others because of inadequate testing for viral pathogens. If a liberal transfusion policy does not improve clinical outcomes, or if it is equivalent, then adopting a more restrictive approach could be recognised as the standard of care.  OBJECTIVES: The aim of this review update was to compare 30-day mortality and other clinical outcomes for participants randomised to restrictive versus liberal red blood cell (RBC) transfusion thresholds (triggers) for all clinical conditions. The restrictive transfusion threshold uses a lower haemoglobin concentration as a threshold for transfusion (most commonly, 7.0 g/dL to 8.0 g/dL), and the liberal transfusion threshold uses a higher haemoglobin concentration as a threshold for transfusion (most commonly, 9.0 g/dL to 10.0 g/dL).

SEARCH METHODS

We identified trials through updated searches: CENTRAL (2020, Issue 11), MEDLINE (1946 to November 2020), Embase (1974 to November 2020), Transfusion Evidence Library (1950 to November 2020), Web of Science Conference Proceedings Citation Index (1990 to November 2020), and trial registries (November 2020). We  checked the reference lists of other published reviews and relevant papers to identify additional trials. We were aware of one trial identified in earlier searching that was in the process of being published (in February 2021), and we were able to include it before this review was finalised.

SELECTION CRITERIA

We included randomised trials of surgical or medical participants that recruited adults or children, or both. We excluded studies that focused on neonates. Eligible trials assigned intervention groups on the basis of different transfusion schedules or thresholds or 'triggers'. These thresholds would be defined by a haemoglobin (Hb) or haematocrit (Hct) concentration below which an RBC transfusion would be administered; the haemoglobin concentration remains the most commonly applied marker of the need for RBC transfusion in clinical practice. We included trials in which investigators had allocated participants to higher thresholds or more liberal transfusion strategies compared to more restrictive ones, which might include no transfusion. As in previous versions of this review, we did not exclude unregistered trials published after 2010 (as per the policy of the Cochrane Injuries Group, 2015), however, we did conduct analyses to consider the differential impact of results of trials for which prospective registration could not be confirmed.   DATA COLLECTION AND ANALYSIS: We identified trials for inclusion and extracted data using Cochrane methods. We pooled risk ratios of clinical outcomes across trials using a random-effects model. Two review authors independently extracted data and assessed risk of bias. We conducted predefined analyses by clinical subgroups. We defined participants randomly allocated to the lower transfusion threshold as being in the 'restrictive transfusion' group and those randomly allocated to the higher transfusion threshold as being in the 'liberal transfusion' group.

MAIN RESULTS

A total of 48 trials, involving data from 21,433 participants (at baseline), across a range of clinical contexts (e.g. orthopaedic, cardiac, or vascular surgery; critical care; acute blood loss (including gastrointestinal bleeding); acute coronary syndrome; cancer; leukaemia; haematological malignancies), met the eligibility criteria. The haemoglobin concentration used to define the restrictive transfusion group in most trials (36) was between 7.0 g/dL and 8.0 g/dL.  Most trials included only adults; three trials focused on children. The included studies were generally at low risk of bias for key domains including allocation concealment and incomplete outcome data. Restrictive transfusion strategies reduced the risk of receiving at least one RBC transfusion by 41% across a broad range of clinical contexts (risk ratio (RR) 0.59, 95% confidence interval (CI) 0.53 to 0.66; 42 studies, 20,057 participants; high-quality evidence), with a large amount of heterogeneity between trials (I² = 96%). Overall, restrictive transfusion strategies did not increase or decrease the risk of 30-day mortality compared with liberal transfusion strategies (RR 0.99, 95% CI 0.86 to 1.15; 31 studies, 16,729 participants; I² = 30%; moderate-quality evidence) or any of the other outcomes assessed (i.e. cardiac events (low-quality evidence), myocardial infarction, stroke, thromboembolism (all high-quality evidence)). High-quality evidence shows that the liberal transfusion threshold did not affect the risk of infection (pneumonia, wound infection, or bacteraemia). Transfusion-specific reactions are uncommon and were inconsistently reported within trials. We noted less certainty in the strength of evidence to support the safety of restrictive transfusion thresholds for the following predefined clinical subgroups: myocardial infarction, vascular surgery, haematological malignancies, and chronic bone-marrow disorders.

AUTHORS' CONCLUSIONS

Transfusion at a restrictive haemoglobin concentration decreased the proportion of people exposed to RBC transfusion by 41% across a broad range of clinical contexts. Across all trials, no evidence suggests that a restrictive transfusion strategy impacted 30-day mortality, mortality at other time points, or morbidity (i.e. cardiac events, myocardial infarction, stroke, pneumonia, thromboembolism, infection) compared with a liberal transfusion strategy. Despite including 17 more randomised trials (and 8846 participants), data remain insufficient to inform the safety of transfusion policies in important and selected clinical contexts, such as myocardial infarction, chronic cardiovascular disease, neurological injury or traumatic brain injury, stroke, thrombocytopenia, and cancer or haematological malignancies, including chronic bone marrow failure.  Further work is needed to improve our understanding of outcomes other than mortality. Most trials compared only two separate thresholds for haemoglobin concentration, which may not identify the actual optimal threshold for transfusion in a particular patient. Haemoglobin concentration may not be the most informative marker of the need for transfusion in individual patients with different degrees of physiological adaptation to anaemia. Notwithstanding these issues, overall findings provide good evidence that transfusions with allogeneic RBCs can be avoided in most patients with haemoglobin thresholds between the range of 7.0 g/dL and 8.0 g/dL. Some patient subgroups might benefit from RBCs to maintain higher haemoglobin concentrations; research efforts should focus on these clinical contexts.

Optimizing red blood cell transfusion practices in the intensive care unit: a multi-phased health technology reassessment

Background

Health technology reassessment (HTR) is a process to manage existing health technologies to ensure ongoing optimal use. A model to guide HTR was developed; however, there is limited practical experience. This paper addresses this knowledge gap through the completion of a multi-phase HTR of red blood cell (RBC) transfusion practices in the intensive care unit (ICU).

Objective

The HTR consisted of three phases and here we report on the final phase: the development, implementation, and evaluation of behavior change interventions aimed at addressing inappropriate RBC transfusions in an ICU.

Methods

The interventions, comprised of group education and audit and feedback, were co-designed and implemented with clinical leaders. The intervention was evaluated through a controlled before-and-after pilot feasibility study. The primary outcome was the proportion of potentially inappropriate RBC transfusions (i.e., with a pre-transfusion hemoglobin of 70 g/L or more).

Results

There was marked variability in the monthly proportion of potentially inappropriate RBC transfusions. Relative to the pre-intervention phase, there was no significant difference in the proportion of potentially inappropriate RBC transfusions post-intervention. Lessons from this work include the importance of early and meaningful engagement of clinical leaders; tailoring the intervention modalities; and, efficient access to data through an electronic clinical information system.

Conclusions

It was feasible to design, implement, and evaluate a tailored, multi-modal behavior change intervention in this small-scale pilot study. However, early evaluation of the intervention revealed no change in technology use leading to reflection on the important question of how the HTR model needs to be improved.

Theory and practical guidance for effective de-implementation of practices across health and care services: a realist synthesis

Background

Health-care systems across the globe are facing increased pressures to balance the efficient use of resources and at the same time provide high-quality care. There is greater requirement for services to be evidence based, but practices that are of limited clinical effectiveness or cost-effectiveness still occur.

Objectives

Our objectives included completing a concept analysis of de-implementation, surfacing decision-making processes associated with de-implementing through stakeholder engagement, and generating an evidence-based realist programme theory of ‘what works’ in de-implementation.

Design

A realist synthesis was conducted using an iterative stakeholder-driven four-stage approach. Phase 1 involved scoping the literature and conducting stakeholder interviews to develop the concept analysis and an initial programme theory. In Phase 2, systematic searches of the evidence were conducted to test and develop this theory, expressed in the form of contingent relationships. These are expressed as context–mechanism–outcomes to show how particular contexts or conditions trigger mechanisms to generate outcomes. Phase 3 consisted of validation and refinement of programme theories through stakeholder interviews. The final phase (i.e. Phase 4) formulated actionable recommendations for service leaders.

Participants

In total, 31 stakeholders (i.e. user/patient representatives, clinical managers, commissioners) took part in focus groups and telephone interviews.

Data sources

Using keywords identified during the scoping work and concept analysis, searches of bibliographic databases were conducted in May 2018. The databases searched were the Cochrane Library, Campbell Collaboration, MEDLINE (via EBSCOhost), the Cumulative Index to Nursing and Allied Health Literature (via EBSCOhost), the National Institute for Health Research Journals Library and the following databases via the ProQuest platform: Applied Social Sciences Index and Abstracts, Social Services Abstracts, International Bibliography of the Social Sciences, Social Sciences Database and Sociological Abstracts. Alerts were set up for the MEDLINE database from May 2018 to December 2018. Online sources were searched for grey literature and snowballing techniques were used to identify clusters of evidence.

Results

The concept analysis showed that de-implementation is associated with five main components in context and over time: (1) what is being de-implemented, (2) the issues driving de-implementation, (3) the action characterising de-implementation, (4) the extent that de-implementation is planned or opportunistic and (5) the consequences of de-implementation. Forty-two papers were synthesised to identify six context–mechanism–outcome configurations, which focused on issues ranging from individual behaviours to organisational procedures. Current systems can perpetuate habitual decision-making practices that include low-value treatments. Electronic health records can be designed to hide or remove low-value treatments from choice options, foregrounding best evidence. Professionals can be made aware of their decision-making strategies through increasing their attention to low-value practice behaviours. Uncertainty about diagnosis or patients’ expectations for certain treatments provide opportunities for ‘watchful waiting’ as an active strategy to reduce inappropriate investigations and prescribing. The emotional component of clinician–patient relationships can limit opportunities for de-implementation, requiring professional support through multimodal educational interventions. Sufficient alignment between policy, public and professional perspectives is required for de-implementation success.

Limitations

Some specific clinical issues (e.g. de-prescribing) dominate the de-implementation evidence base, which may limit the transferability of the synthesis findings. Any realist inquiry generates findings that are essentially cumulative and should be developed through further investigation that extends the range of sources into, for example, clinical research and further empirical studies.

Conclusions

This review contributes to our understanding of how de-implementation of low-value procedures and services can be improved within health-care services, through interventions that make professional decision-making more accountable and the prominence of a whole-system approach to de-implementation. Given the whole-system context of de-implementation, a range of different dissemination strategies will be required to engage with different stakeholders, in different ways, to change practice and policy in a timely manner.

Enhancing the translation of health behaviour change research into practice: a selective conceptual review of the synergy between implementation science and health psychology

Health psychology is at the forefront of developing and disseminating evidence, theories, and methods that have improved the understanding of health behaviour change. However, current dissemination approaches may be insufficient for promoting broader application and impact of this evidence to benefit the health of patients and the public. Nevertheless, behaviour change theory/methods typically directed towards health behaviours are now used in implementation science to understand and support behaviour change in individuals at different health system levels whose own behaviour impacts delivering evidence-based health behaviour change interventions. Despite contributing to implementation science, health psychology is perhaps doing less to draw from it. A redoubled focus on implementation science in health psychology could provide novel prospects for enhancing the impact of health behaviour change evidence. We report a Health Psychology Review-specific review-of-reviews of trials of health behaviour change interventions published from inception to April 2020. We identified 34 reviews and assessed whether implementation readiness of behaviour change interventions was discussed. We then narratively review how implementation science has integrated theory/methods from health psychology and related discipline. Finally, we demonstrate how greater synergy between implementation science and health psychology could promote greater follow-through on advances made in the science of health behaviour change.

Social norms interventions to change clinical behaviour in health workers: a systematic review and meta-analysis

Background

A social norms intervention seeks to change the clinical behaviour of a target health worker by exposing them to the values, beliefs, attitudes or behaviours of a reference group or person. These low-cost interventions can be used to encourage health workers to follow recommended professional practice.

Objective

To summarise evidence on whether or not social norms interventions are effective in encouraging health worker behaviour change, and to identify the most effective social norms interventions.

Design

A systematic review and meta-analysis of randomised controlled trials.

Data sources

The following databases were searched on 24 July 2018: Ovid MEDLINE (1946 to week 2 July 2018), EMBASE (1974 to 3 July 2018), Cumulative Index to Nursing and Allied Health Literature (1937 to July 2018), British Nursing Index (2008 to July 2018), ISI Web of Science (1900 to present), PsycINFO (1806 to week 3 July 2018) and Cochrane trials (up to July 2018).

Participants

Health workers took part in the study.

Interventions

Behaviour change interventions based on social norms.

Outcome measures

Health worker clinical behaviour, for example prescribing (primary outcome), and patient health outcomes, for example blood test results (secondary), converted into a standardised mean difference.

Methods

Titles and abstracts were reviewed against the inclusion criteria to exclude any that were clearly ineligible. Two reviewers independently screened the remaining full texts to identify relevant papers. Two reviewers extracted data independently, coded for behaviour change techniques and assessed quality using the Cochrane risk-of-bias tool. We performed a meta-analysis and presented forest plots, stratified by behaviour change technique. Sources of variation were explored using metaregression and network meta-analysis.

Results

A total of 4428 abstracts were screened, 477 full texts were screened and findings were based on 106 studies. Most studies were in primary care or hospitals, targeting prescribing, ordering of tests and communication with patients. The interventions included social comparison (in which information is given on how peers behave) and credible source (which refers to communication from a well-respected person in support of the behaviour). Combined data suggested that interventions that included social norms components were associated with an improvement in health worker behaviour of 0.08 standardised mean differences (95% confidence interval 0.07 to 0.10 standardised mean differences) (n = 100 comparisons), and an improvement in patient outcomes of 0.17 standardised mean differences (95% confidence interval 0.14 to 0.20) (n = 14), on average. Heterogeneity was high, with an overall I 2 of 85.4% (primary) and 91.5% (secondary). Network meta-analysis suggested that three types of social norms intervention were most effective, on average, compared with control: credible source (0.30 standardised mean differences, 95% confidence interval 0.13 to 0.47); social comparison combined with social reward (0.39 standardised mean differences, 95% confidence interval 0.15 to 0.64); and social comparison combined with prompts and cues (0.33 standardised mean differences, 95% confidence interval 0.22 to 0.44).

Limitations

The large number of studies prevented us from requesting additional information from authors. The trials varied in design, context and setting, and we combined different types of outcome to provide an overall summary of evidence, resulting in a very heterogeneous review.

Conclusions

Social norms interventions are an effective method of changing clinical behaviour in a variety of health service contexts. Although the overall result was modest and very variable, there is the potential for social norms interventions to be scaled up to target the behaviour of a large population of health workers and resulting patient outcomes.

Future work

Development of optimised credible source and social comparison behaviour change interventions, including qualitative research on acceptability and feasibility.

Multiple-dose tranexamic acid for perioperative blood loss in total knee arthroplasty in patients with rheumatoid arthritis：a single-blinded, randomised, parallel-controlled study protocol in China

INTRODUCTION

This clinical trial is designed to evaluate the effect of multiple-dose tranexamic acid (TXA) on perioperative blood loss in patients with rheumatoid arthritis (RA).

METHODS AND ANALYSIS

A randomised, single-blinded, parallel-controlled study will be designed. Patients with RA (age 50-75 years) undergoing unilateral primary end-stage total knee arthroplasty will be randomly divided into group A or group B. Group A will be treated with one dose of TXA (1 g; intravenous injection 3 hours postsurgery) and group B with three doses (1 g; intravenous injection at 3, 6 and 12 hours postsurgery) after surgery. The primary outcomes will be evaluated with blood loss, maximum haemoglobin drop and transfusion rate. The secondary outcomes will be evaluated with knee function and complications.

ETHICS AND DISSEMINATION

The Shanghai Guanghua Hospital of Integrated Traditional Chinese Medicine and Western Medicine Ethics Committee approved in this study in July 2019. Informed consent will be obtained from all participants. Results of the trial will be published in the Dryad and repository in a peer-reviewed journal. Additionally, deidentified data collected and analysed for this study will be available for review from the corresponding author on reasonable request.

Use of the theoretical domains framework and behaviour change wheel to develop a novel intervention to improve the quality of multidisciplinary cancer conference decision-making

BACKGROUND

Multidisciplinary Cancer Conferences (MCCs) are prospective meetings involving cancer specialists to discuss treatment plans for patients with cancer. Despite reported gaps in MCC quality, there have been few efforts to improve its functioning. The purpose of this study was to use theoretically-rooted knowledge translation (KT) theories and frameworks to inform the development of a strategy to improve MCC decision-making quality.

METHODS

A multi-phased approach was used to design an intervention titled the KT-MCC Strategy. First, key informant interviews framed using the Theoretical Domains Framework (TDF) were conducted with MCC participants to identify barriers and facilitators to optimal MCC decision-making. Second, identified TDF domains were mapped to corresponding strategies using the COM-B Behavior Change Wheel to develop the KT-MCC Strategy. Finally, focus groups with MCC participants were held to confirm acceptability of the proposed KT-MCC Strategy.

RESULTS

Data saturation was reached at n = 21 interviews. Twenty-seven barrier themes and 13 facilitator themes were ascribed to 11 and 10 TDF domains, respectively. Differences in reported barriers by physician specialty were observed. The resulting KT-MCC Strategy included workshops, chair training, team training, standardized intake forms and a synoptic discussion checklist, and, audit and feedback. Focus groups (n = 3, participants 18) confirmed the acceptability of the identified interventions.

CONCLUSION

Myriad factors were found to influence MCC decision making. We present a novel application of the TDF and COM-B to the context of MCCs. We comprehensively describe the barriers and facilitators that impact MCC decision making and propose strategies that may positively impact the quality of MCC decision making.

Perspectives on program mis-implementation among U.S. local public health departments

BACKGROUND

Public health resources are limited and best used for effective programs. This study explores associations of mis-implementation in public health (ending effective programs or continuing ineffective programs) with organizational supports for evidence-based decision making among U.S. local health departments.

METHODS

The national U.S. sample for this cross-sectional study was stratified by local health department jurisdiction population size. One person was invited from each randomly selected local health department: the leader in chronic disease, or the director. Of 600 selected, 579 had valid email addresses; 376 completed the survey (64.9% response). Survey items assessed frequency of and reasons for mis-implementation. Participants indicated agreement with statements on organizational supports for evidence-based decision making (7-point Likert).

RESULTS

Thirty percent (30.0%) reported programs often or always ended that should have continued (inappropriate termination); organizational supports for evidence-based decision making were not associated with the frequency of programs ending. The main reason given for inappropriate termination was grant funding ended (86.0%). Fewer (16.4%) reported programs often or always continued that should have ended (inappropriate continuation). Higher perceived organizational supports for evidence-based decision making were associated with less frequent inappropriate continuation (odds ratio = 0.86, 95% confidence interval 0.79, 0.94). All organizational support factors were negatively associated with inappropriate continuation. Top reasons were sustained funding (55.6%) and support from policymakers (34.0%).

CONCLUSIONS

Organizational supports for evidence-based decision making may help local health departments avoid continuing programs that should end. Creative mechanisms of support are needed to avoid inappropriate termination. Understanding what influences mis-implementation can help identify supports for de-implementation of ineffective programs so resources can go towards evidence-based programs.

Decreasing the number of arthroscopies in knee osteoarthritis - a service evaluation of a de-implementation strategy

BACKGROUND

The Personalised Knee Improvement Programme (P-KIP) was developed based on previously published work, with the hypothesis that surgeons would refer patients to a well-structured conservative management intervention instead of for arthroscopy (de-implementation of arthroscopy by substitution with P-KIP). This meets NICE guidelines and international recommendations but such programmes are not widely used in the UK. Our aim was to determine whether P-KIP would reduce the number of arthroscopies performed for knee osteoarthritis.

METHODS

P-KIP is a conservative care pathway including a group education session followed by individually tailored one-to-one dietician and physiotherapy sessions. Virtual clinic follow-up is conducted three to 6 months after completion of the programme. The service began in July 2015. The number of arthroscopies saved, measured from hospital level coding data, is the primary outcome measure. Interrupted time series analysis of coding data was conducted. As a quality assurance process, patient reported outcome measures (Oxford Knee Score; Euroqol 5D) were collected at baseline and at follow up.

RESULTS

Time series analysis demonstrates that the programme saved 15.4 arthroscopies a month (95% confidence interval 9-21; p < 0.001), equating to 184 arthroscopies a year in a single hospital. The PROMs data demonstrated improvements in patient reported outcome scores consistent with previous published reports of conservative interventions in similar patient populations.

CONCLUSIONS

Results suggest that P-KIP reduces the number of arthroscopies performed, and patients who took part in P-KIP had an improvement in their knee and general health outcomes. P-KIP has the potential to deliver efficiency savings and relive pressure on operative lists, however replication in other sites is required.

Barriers and Facilitators to De-Implementation of the Choosing Wisely® Guidelines for Low-Value Breast Cancer Surgery

BACKGROUND

To address overuse of unnecessary practices, several surgical organizations have participated in the Choosing Wisely^® campaign and identified four breast cancer surgical procedures as unnecessary. Despite evidence demonstrating no survival benefit for all four, evidence suggests only two have been substantially de-implemented. Our objective was to understand why surgeons stop performing certain unnecessary cancer operations but not others and how best to de-implement entrenched and emerging unnecessary procedures.

METHODS

We sampled surgeons who treat breast cancer in a variety of practice types and geographic regions in the United States. Using a semi-structured guide, we conducted telephone interviews (n = 18) to elicit attitudes and understand practices relating to the four identified breast cancer procedures in the Choosing Wisely^® campaign. Interviews were recorded, transcribed, and anonymized. Transcripts were analyzed using inductive and deductive thematic analysis.

RESULTS

For the two procedures successfully de-implemented, surgeons described a high level of confidence in the data supporting the recommendations. In contrast, surgeons frequently described a lack of familiarity or skepticism toward the recommendation to avoid sentinel-node biopsy in women ≥ 70 years of age and the influence of other collaborating oncology providers as justification for continued use. Regarding contralateral prophylactic mastectomy, surgeons consistently agreed with the recommendation that this was unnecessary, yet reported continued utilization due to the value placed on patient autonomy and preference.

CONCLUSIONS

With a growing focus on the elimination of ineffective, unproven or low value practices, it is imperative that the behavioral determinants are understood and targeted with specific interventions to decrease utilization rapidly.

Comparative Analysis Investigating the Impact of Implant Design on Hospital Length of Stay and Discharge Destination in a Dutch Hospital With an Established Enhanced Recovery Program

BACKGROUND

Global demand for total knee arthroplasty (TKA) is increasing, driven by an aging and increasingly overweight patient population, culminating in higher healthcare costs. In the Netherlands, the number of TKA surgeries performed annually increased from 21,000 in 2010 to 29,000 in 2017. This study aimed to assess the impact of implant design on hospital length of stay (LOS), surgery time, and discharge destination (home vs a rehabilitation center) in a Dutch hospital with an established enhanced recovery program and short baseline LOS.

METHODS

A retrospective review of consecutive adult patients who underwent primary TKA in a Dutch hospital between 2015 and 2017 using either the comparator device or the control device.

RESULTS

A total of 200 patients were enrolled in the study (100 per group). Patients who received a comparator device had a significantly shorter LOS (adjusted mean 2.76 days; 95% confidence interval [CI]: 2.45, 3.11) vs the control group (adjusted mean 3.43 days; 95% CI: 3.08, 3.81; P < .01). The proportion of patients discharged to a rehabilitation center, instead of home, was also significantly lower in the comparator device group (adjusted 4.4%; 95% CI: 1.8, 10.7 vs adjusted 11.4%; 95% CI: 6.0, 20.6; P < .05). There was no difference in surgical time between the 2 groups. None of the sensitivity analyses performed affected the original analysis outcome.

CONCLUSION

This study shows a modest but significant reduction in length of stay and lower rate of discharge to a rehabilitation center in the comparator device group.

Blood management in fast-track orthopedic surgery: an evidence-based narrative review

BACKGROUND AND PURPOSE

Innovations able to maintain patient safety while reducing the amount of transfusion add value to orthopedic procedures. Opportunities for improvement arise especially in elective procedures, as long as room for planning is available. Although many strategies have been proposed, there is no consensus about the most successful combination. The purpose of this investigation is to identify information to support blood management strategies in fast-track total joint arthroplasty (TJA) pathway, to (i) support clinical decision making according to current evidence and best practices, and (ii) identify critical issues which need further research.

METHODS AND MATERIALS

We identified conventional blood management strategies in elective orthopedic procedures. We performed an electronic search about blood management strategies in fast-track TJA. We designed tables to match every step of the former with the latter. We submitted the findings to clinicians who operate using fast-track surgery protocols in TJA at our research hospital.

RESULTS

Preoperative anemia detection and treatment, blood anticoagulants/aggregants consumption, transfusion trigger, anesthetic technique, local infiltration analgesia, drainage clamping and removals, and postoperative multimodal thromboprophylaxis are the factors which can add best value to a fast-track pathway, since they provide significant room for planning and prediction.

CONCLUSION

The difference between conventional and fast-track pathways does not lie in the contents of blood management, which are related to surgeons/surgeries, materials used and patients, but in the way these contents are integrated into each other, since elective orthopedic procedures offer significant room for planning. Further studies are needed to identify optimal regimens.

Changing behaviour 'more or less'-do theories of behaviour inform strategies for implementation and de-implementation? A critical interpretive synthesis

BACKGROUND

Implementing evidence-based care requires healthcare practitioners to do less of some things (de-implementation) and more of others (implementation). Variations in effectiveness of behaviour change interventions may result from failure to consider a distinction between approaches by which behaviour increases and decreases in frequency. The distinction is not well represented in methods for designing interventions. This review aimed to identify whether there is a theoretical rationale to support this distinction.

METHODS

Using Critical Interpretative Synthesis, this conceptual review included papers from a broad range of fields (biology, psychology, education, business) likely to report approaches for increasing or decreasing behaviour. Articles were identified from databases using search terms related to theory and behaviour change. Articles reporting changes in frequency of behaviour and explicit use of theory were included. Data extracted were direction of behaviour change, how theory was operationalised, and theory-based recommendations for behaviour change. Analyses of extracted data were conducted iteratively and involved inductive coding and critical exploration of ideas and purposive sampling of additional papers to explore theoretical concepts in greater detail.

RESULTS

Critical analysis of 66 papers and their theoretical sources identified three key findings: (1) 9 of the 15 behavioural theories identified do not distinguish between implementation and de-implementation (5 theories were applied to only implementation or de-implementation, not both); (2) a common strategy for decreasing frequency was substituting one behaviour with another. No theoretical basis for this strategy was articulated, nor were methods proposed for selecting appropriate substitute behaviours; (3) Operant Learning Theory makes an explicit distinction between techniques for increasing and decreasing frequency.

DISCUSSION

Behavioural theories provide little insight into the distinction between implementation and de-implementation. Operant Learning Theory identified different strategies for implementation and de-implementation, but these strategies may not be acceptable in health systems. Additionally, if behaviour substitution is an approach for de-implementation, further investigation may inform methods or rationale for selecting the substitute behaviour.

Letting Go: Conceptualizing Intervention De-implementation in Public Health and Social Service Settings

The discontinuation of interventions that should be stopped, or de-implementation, has emerged as a novel line of inquiry within dissemination and implementation science. As this area grows in human services research, like public health and social work, theory is needed to help guide scientific endeavors. Given the infancy of de-implementation, this conceptual narrative provides a definition and criteria for determining if an intervention should be de-implemented. We identify three criteria for identifying interventions appropriate for de-implementation: (a) interventions that are not effective or harmful, (b) interventions that are not the most effective or efficient to provide, and (c) interventions that are no longer necessary. Detailed, well-documented examples illustrate each of the criteria. We describe de-implementation frameworks, but also demonstrate how other existing implementation frameworks might be applied to de-implementation research as a supplement. Finally, we conclude with a discussion of de-implementation in the context of other stages of implementation, like sustainability and adoption; next steps for de-implementation research, especially identifying interventions appropriate for de-implementation in a systematic manner; and highlight special ethical considerations to advance the field of de-implementation research.

De-implementation: A concept analysis

AIM

The purpose of this concept analysis is to explore the meaning of de-implementation and provide a definition that can be used by researchers and clinicians to facilitate evidence-based practice.

BACKGROUND

De-implementation is a relatively unknown process overshadowed by the novelty of introducing new ideas and techniques into practice. Few studies have addressed the challenge of de-implementation and the cognitive processes involved when terminating harmful or unnecessary practices. Also, confusion exists regarding the myriad of terms used to describe de-implementation processes.

DESIGN

Walker and Avant's method (2011) for describing concepts was used to clarify de-implementation.

DATA SOURCE

A database search limited to academic journals yielded 281 publications representing basic research, study protocols, and editorials/commentaries from implementation science experts. After applying exclusion criterion of English language only and eliminating overlap between databases, 41 articles were selected for review.

REVIEW METHODS

Literature review and synthesis provided a concept analysis and a distinct definition of de-implementation.

RESULTS

De-implementation was defined as the process of identifying and removing harmful, non-cost-effective, or ineffective practices based on tradition and without adequate scientific support.

CONCLUSIONS

The analysis provided further refinement of de-implementation as a significant concept for ongoing theory development in implementation science and clinical practice.

Towards a systematic approach for (de)implementation of patient blood management strategies

Despite the increasing availability of evidence in transfusion medicine literature, this evidence does not automatically find its way into practice. This is also applicable to patient blood management (PBM). It may concern the lack of implementation of effective new techniques or treatments, or it may apply to the (over)use of techniques and treatments (e.g. inappropriate transfusions) that have proven to be of limited benefit for patients (low-value care) and could be abandoned (de-implementation). In PBM literature, the implementation of restrictive transfusion thresholds and the de-implementation of inappropriate transfusions are described. However, most implementation strategies were not preceded by the identification of relevant barriers, and the used strategies were not often supported by literature on behavioural changes. In this article, we describe implementation vs de-implementation, highlight the current situation of (de)implementation in PBM and describe a systematic approach for (de)implementation illustrated by an example of a PBM de-implementation study regarding '(cost-) effective patient blood management in total hip and knee arthroplasty'. The systematic approach used for (de)implementation is based on the implementation model of Grol, which consists of the following five steps: the detection of improvement goals, a problem analysis, the selection of (de)implementation strategies, the execution of the (de)implementation strategy and an evaluation. Based on the description of the current situation and the experiences in our de-implementation study, we can conclude that de-implementation may be more difficult than expected as other factors may play a role in effective de-implementation compared to implementation.

How the dual process model of human cognition can inform efforts to de-implement ineffective and harmful clinical practices: A preliminary model of unlearning and substitution

RATIONALE AND OBJECTIVES

One way to understand medical overuse at the clinician level is in terms of clinical decision-making processes that are normally adaptive but become maladaptive. In psychology, dual process models of cognition propose 2 decision-making processes. Reflective cognition is a conscious process of evaluating options based on some combination of utility, risk, capabilities, and/or social influences. Automatic cognition is a largely unconscious process occurring in response to environmental or emotive cues based on previously learned, ingrained heuristics. De-implementation strategies directed at clinicians may be conceptualized as corresponding to cognition: (1) a process of unlearning based on reflective cognition and (2) a process of substitution based on automatic cognition.

RESULTS

We define unlearning as a process in which clinicians consciously change their knowledge, beliefs, and intentions about an ineffective practice and alter their behaviour accordingly. Unlearning has been described as "the questioning of established knowledge, habits, beliefs and assumptions as a prerequisite to identifying inappropriate or obsolete knowledge underpinning and/or embedded in existing practices and routines." We hypothesize that as an unintended consequence of unlearning strategies clinicians may experience "reactance," ie, feel their professional prerogative is being violated and, consequently, increase their commitment to the ineffective practice. We define substitution as replacing the ineffective practice with one or more alternatives. A substitute is a specific alternative action or decision that either precludes the ineffective practice or makes it less likely to occur. Both approaches may work independently, eg, a substitute could displace an ineffective practice without changing clinicians' knowledge, and unlearning could occur even if no alternative exists. For some clinical practice, unlearning and substitution strategies may be most effectively used together.

CONCLUSIONS

By taking into account the dual process model of cognition, we may be able to design de-implementation strategies matched to clinicians' decision-making processes and avoid unintended consequence.
