Association between a genetic index for digital dermatitis resistance and the presence of digital dermatitis, heel horn erosion and interdigital hyperplasia in Holstein cows

Digital dermatitis (DD) is a polybacterial disease endemic to most UK dairy farms. It poses a major financial and welfare threat and is characterized by high incidence and recurrence rates. We aimed to investigate the association between the UK estimated breeding value for resistance to digital dermatitis, the Digital Dermatitis Index (DDI) and the frequency of DD, heel horn erosion (HHE), and interdigital hyperplasia (IH) in a population of Holstein dairy cows. We enrolled and genotyped 2,352 cows from 4 farms in a prospective cohort study. Foot lesion records were recorded by veterinary surgeons for each animal at 4 time points during a production cycle, starting at approximately 2 mo before calving and ending in late lactation. Importantly, these records were not used in the calculation of the DDI. Lesion records were matched to the animal's own DDI (n = 2,101) and their sire's DDI (n = 1,812). Digital Dermatitis Index values in our study population ranged from -1.41 to +1.2 and were transformed to represent distance from the mean expressed in standard deviations. The relationship between the DDI and the presence of DD was investigated using a logistic regression model, with farm, parity, and a farm-parity interaction fitted as covariates. A multivariable logistic regression model was fitted to evaluate the relationship between HHE and DDI with farm fitted as a covariate. Finally, a univariable logistic regression model with DDI as explanatory variable was used to investigate the relationship between IH and DDI. The odds ratio of an animal being affected by DD was 0.69 for one standard deviation (SD) increase in the animal's DDI (95% confidence interval (CI) = 0.63-0.76). The odds of HHE and IH were 0.69 (95%CI = 0.62-0.76) and 0.58 (95%CI = 0.49-0.68) respectively for one SD increase in DDI. The adjusted probability of DD was 32% (95% CI = 27-36%) for cows with mean DDI value of 0 while it was 24% (95% CI = 20-29%) in cows with a DDI value of +1. Sire DDI breeding values were standardized in the same way and then binned into terciles creating an ordinal variable representing bulls of high, medium, and low genetic merit for DD resistance. The daughters of low genetic merit bulls were at 2.05 (95% CI = 1.60-2.64), 1.96 (95% CI = 1.53-2.50), and 2.85 (95% CI = 1.64-5.16) times greater odds of being affected by DD, HHE, and IH respectively compared with the daughters of high genetic merit bulls. The results of this study highlight the potential of digital dermatitis genetic indexes to aid herd management of DD, and suggest that breeding for resistance to DD, alongside environmental and management control practices, could reduce the prevalence of the disease.

Racial and ethnic disparities in common inpatient safety outcomes in a children's hospital cohort

BACKGROUND

Emerging evidence has shown racial and ethnic disparities in rates of harm for hospitalised children. Previous work has also demonstrated how highly heterogeneous approaches to collection of race and ethnicity data pose challenges to population-level analyses. This work aims to both create an approach to aggregating safety data from multiple hospitals by race and ethnicity and apply the approach to the examination of potential disparities in high-frequency harm conditions.

METHODS

In this cross-sectional, multicentre study, a cohort of hospitals from the Solutions for Patient Safety network with varying race and ethnicity data collection systems submitted validated central line-associated bloodstream infection (CLABSI) and unplanned extubation (UE) data stratified by patient race and ethnicity categories. Data were submitted using a crosswalk created by the study team that reconciled varying approaches to race and ethnicity data collection by participating hospitals. Harm rates for race and ethnicity categories were compared with reference values reflective of the cohort and broader children's hospital population.

RESULTS

Racial and ethnic disparities were identified in both harm types. Multiracial Hispanic, Combined Hispanic and Native Hawaiian or other Pacific Islander patients had CLABSI rates of 2.6-3.6 SD above reference values. For Black or African American patients, UE rates were 3.2-4.4 SD higher. Rates of both events in White patients were significantly lower than reference values.

CONCLUSIONS

The combination of harm data across hospitals with varying race and ethnicity collection systems was accomplished through iterative development of a race and ethnicity category framework. We identified racial and ethnic disparities in CLABSI and UE that can be addressed in future improvement work by identifying and modifying care delivery factors that contribute to safety disparities.

Pediatric Ventilator-Associated Events Before and After a Multicenter Quality Improvement Initiative

Importance

Pediatric ventilator-associated events (PedVAEs, defined as a sustained worsening in oxygenation after a baseline period of stability or improvement) are useful for surveillance of complications from mechanical ventilation. It is unclear whether interventions to mitigate known risk factors can reduce PedVAE rates.

Objective

To assess whether adherence to 1 or more test factors in a quality improvement bundle was associated with a reduction in PedVAE rates.

Design, Setting, and Participants

This multicenter quality improvement study obtained data from 2017 to 2020 for patients who were mechanically ventilated and cared for in neonatal, pediatric, and cardiac intensive care units (ICUs). These ICUs were located in 95 hospitals participating in the Children's Hospitals' Solutions for Patient Safety (SPS) network in North America. Data analyses were performed between September 2021 and April 2023.

Intervention

A quality improvement bundle consisted of 3 test factors: multidisciplinary apparent cause analysis, daily discussion of extubation readiness, and daily discussion of fluid balance goals. This bundle was distributed to a subgroup of hospitals that volunteered to participate in a collaborative PedVAE prevention initiative under the SPS network guidance in July 2018.

Main Outcomes and Measures

Each SPS network hospital submitted monthly PedVAE rates from January 1, 2017, to May 31, 2020, and test factor data were submitted from July 1, 2018, to May 31, 2020. Analyses focused on hospitals that reliably submitted PedVAE rate data, defined as outcomes data submission through May 31, 2020, for at least 80% of the baseline and postbaseline periods.

Results

Of the 95 hospitals in the SPS network that reported PedVAE data, 21 were grouped in the Pioneer cohort and 74 in the non-Pioneer cohort. Only 12 hospitals (57%) from the 21 Pioneer hospitals and 33 (45%) from the 74 non-Pioneer hospitals were considered to be reliable reporters of outcome data. Among the 12 hospitals, the PedVAE rate decreased from 1.9 to 1.4 events per 1000 ventilator days (absolute rate difference, -0.6; 95% CI, -0.5 to -0.7; P < .001). No significant change in the PedVAE rate was seen among the 33 hospitals that reliably submitted PedVAE rates but did not implement the bundle. Of the 12 hospitals, 3 that reliably performed daily discussion of extubation readiness had a decrease in PedVAE rate from 2.6 to 1.2 events per 1000 ventilator days (absolute rate difference, -1.4; 95% CI, -1.0 to -1.7; P < .001), whereas the other 9 hospitals that did not implement this discussion did not have a decrease.

Conclusions and Relevance

This study found that a multicenter quality improvement intervention targeting PedVAE risk factors was associated with a substantial reduction in the rate of PedVAEs in hospital ICUs. The findings suggest that ICU teams seeking to reduce PedVAEs incorporate daily discussion of extubation readiness during morning rounds.

Compliance With Central Line Maintenance Bundle and Infection Rates

BACKGROUND

Reliable bundle performance is the mainstay of central line-associated bloodstream infections (CLABSI) prevention despite an unclear relationship between bundle reliability and outcomes. Our primary objective was to evaluate the correlation between reported bundle compliance and CLABSI rate in the Solutions for Patient Safety network. The secondary objective was to identify which hospital and process factors impact this correlation.

METHODS

We examined data on bundle compliance and monthly CLABSI rates from January 11 to December 21 in 159 hospitals. The correlation (adjusting for temporal trend) between CLABSI rates and bundle compliance was done at the network level. Negative binomial regression was done to detect the impact of hospital type, central line audit rate, and adoption of a comprehensive safety culture program on the association between bundle compliance and CLABSI rates.

RESULTS

During the study, hospitals reported 27 196 CLABSI on 20 274 565 line days (1.34 CLABSI/1000 line days). Out of 2 460 133 observed bundle opportunities, 2 085 700 (84%) were compliant. There was a negative correlation between the monthly bundle reliability and monthly CLABSI rate (-0.35, P <.001). After adjusting for the temporal trend, the partial correlation was -0.25 (P = .004). On negative binomial regression, significant positive interaction was only noted for the hospital type, with Hospital Within Hospital (but not freestanding children's hospitals) revealing a significant association between compliance ≥95% and lower CLABSI rates.

CONCLUSIONS

Adherence to best practice guidelines is associated with a reduction in CLABSI rate. Hospital-level factors (hospitals within hospitals vs freestanding), but not process-related (central line audit rate and safety culture training), impact this association.

Applying an equity lens to hospital safety monitoring: a critical interpretive synthesis protocol

INTRODUCTION

Hospital safety monitoring systems are foundational to how adverse events are identified and addressed. They are well positioned to bring equity-related safety issues to the forefront for action. However, there is uncertainty about how they have been, and can be, used to achieve this goal. We will undertake a critical interpretive synthesis (CIS) to examine how equity is integrated into hospital safety monitoring systems.

METHODS AND ANALYSIS

This review will follow CIS principles. Our initial compass question is: How is equity integrated into safety monitoring systems? We will begin with a structured search strategy of hospital safety monitoring systems in CINAHL, EMBASE, MEDLINE and PsycINFO for up to May 2023 to identify papers on safety monitoring systems generally and those linked to equity (eg, racism, social determinants of health). We will also review reference lists of selected papers, contact experts and draw on team expertise. For subsequent literature searching stages, we will use team expertise and expert contacts to purposively search the social science, humanities and health services research literature to support the development of a theoretical understanding of our topic. Following data extraction, we will use interpretive processes to develop themes and a critique of the literature. The above processes of question formulation, article search and selection, data extraction, and critique and synthesis will be iterative and interactive with the goal to develop a theoretical understanding of equity in hospital monitoring systems that will have practice-based implications.

ETHICS AND DISSEMINATION

This review does not require ethical approval because we are reviewing published literature. We aim to publish findings in a peer-reviewed journal and present at conferences.

Exploring the lived experience of patients and families who speak language other than English (LOE) for healthcare: developing a qualitative study

BACKGROUND

Patients who use Languages other than English (LOE) for healthcare communication in an English-dominant region are at increased risk for experiencing adverse events and worse health outcomes in healthcare settings, including in pediatric hospitals. Despite the knowledge that individuals who speak LOE have worse health outcomes, they are often excluded from research studies on the basis of language and there is a paucity of data on ways to address these known disparities. Our work aims to address this gap by generating knowledge to improve health outcomes for children with illness and their families with LEP. BODY: We describe an approach to developing a study with individuals marginalized due to using LOE for healthcare communication, specifically using semi-structured qualitative interviews. The premise of this study is participatory research-our overall goal with this systematic inquiry is to, in collaboration with patients and families with LOE, set an agenda for creating actionable change to address the health information disparities these patients and families experience. In this paper we describe our overarching study design principles, a collaboration framework in working with different stakeholders and note important considerations for study design and execution.

CONCLUSIONS

We have a significant opportunity to improve our engagement with marginalized populations. We also need to develop approaches to including patients and families with LOE in our research given the health disparities they experience. Further, understanding lived experience is critical to advancing efforts to address these well-known health disparities. Our process to develop a qualitative study protocol can serve as an example for engaging this patient population and can serve as a starting point for other groups who wish to develop similar research in this area. Providing high-quality care that meets the needs of marginalized and vulnerable populations is important to achieving an equitable, high-quality health care system. Children and families who use a Language other than English (LOE) in English dominant regions for healthcare have worse health outcomes including a significantly increased risk of experiencing adverse events, longer lengths of stay in hospital settings, and receiving more unnecessary tests and investigations. Despite this, these individuals are often excluded from research studies and the field of participatory research has yet to meaningfully involve them. This paper aims to describe an approach to conducting research with a marginalized population of children and families due to using a LOE. We detail protocol development for a qualitative study exploring the lived experiences of patients and families who use a LOE during hospitalization. We aim to share considerations when conducting research within this population of families with LOE. We highlight learning applied from the field of patient-partner and child and family-centred research and note specific considerations for those with LOE. Developing strong partnerships and adopting a common set of research principles and collaborative framework underlies our approach and initial learnings, which we hope spark additional work in this area.

Modelling growth in Suffolk and Charollais sheep populations using random regression models and validation of constrained polynomial correlation values

Random regression modelling has been used across multiple animal species to model longitudinal data. The random regression model for growth accounts for the genetic correlation between measures of the same trait over time and the wide environmental variability in growth, but this requires adequate weight records across the age range. However, contemporary management practices in sheep in the United Kingdom generally focus on growing lambs and neglect mature weight recordings. This study examined modelling strategies for growth data in Suffolk and Charollais sheep, provided by the Agriculture and Horticulture Development Board, with polynomial random regression modelling with many early life weight recordings but limited weight recordings in mature animals. Two methods were employed to model the data. In Method A, missing mature weight records were predicted for those animals that did not have a recorded mature weight. The animals were sorted into groups based on the identity of their sires and the year in which the animal was born. Mature weight values were predicted within each group with a multiple regression model. The dataset, including predicted values, was analysed with random regression models using polynomials and simple linear regression for animal and permanent environmental (PE) effects. In Method B, the dataset with missing mature weight records was analysed using a random linear regression animal model with random animal and PE effects. Due to problems of convergence because the parameters were close to the boundary space, fixing the correlation between the intercept and slope of the Legendre polynomial at different levels was investigated. The heritability values resulting from the model with a fixed correlation between intercept and slope parameters at 0.5 for the Suffolk dataset resulted in heritability values ranging from 0.2 to 0.5 from 1 to 619 days of age. Corresponding estimates for the Charollais dataset ranged from 0.18 to 0.49 from 1 to 640 days of age. For the Suffolk data, the genetic correlations ranged from 1.00 to 0.08 between weight at day 1 to weight at day 619, while for the Charollais, the correlations ranged from 1.00 to 0.05 from 1 to 640 days of age. Validation procedures were undertaken using a multitrait approach to examine the estimated breeding values when the correlation between the intercept and slope are fixed at different levels. The results indicated that fixing the correlation at 0.5 gave the most appropriate estimates for the Suffolk and Charollais datasets.

Implementation of the I-PASS handoff program in diverse clinical environments: A multicenter prospective effectiveness implementation study

BACKGROUND

Handoff miscommunications are a leading source of medical errors. Harmful medical errors decreased in pediatric academic hospitals following implementation of the I-PASS handoff improvement program. However, implementation across specialties has not been assessed.

OBJECTIVE

To determine if I-PASS implementation across diverse settings would be associated with improvements in patient safety and communication.

DESIGN

Prospective Type 2 Hybrid effectiveness implementation study.

SETTINGS AND PARTICIPANTS

Residents from diverse specialties across 32 hospitals (12 community, 20 academic).

INTERVENTION

External teams provided longitudinal coaching over 18 months to facilitate implementation of an enhanced I-PASS program and monthly metric reviews.

MAIN OUTCOME AND MEASURES

Systematic surveillance surveys assessed rates of resident-reported adverse events. Validated direct observation tools measured verbal and written handoff quality.

RESULTS

2735 resident physicians and 760 faculty champions from multiple specialties (16 internal medicine, 13 pediatric, 3 other) participated. 1942 error surveillance reports were collected. Major and minor handoff-related reported adverse events decreased 47% following implementation, from 1.7 to 0.9 major events/person-year (p < .05) and 17.5 to 9.3 minor events/person-year (p < .001). Implementation was associated with increased inclusion of all five key handoff data elements in verbal (20% vs. 66%, p < .001, n = 4812) and written (10% vs. 74%, p < .001, n = 1787) handoffs, as well as increased frequency of handoffs with high quality verbal (39% vs. 81% p < .001) and written (29% vs. 78%, p < .001) patient summaries, verbal (29% vs. 78%, p < .001) and written (24% vs. 73%, p < .001) contingency plans, and verbal receiver syntheses (31% vs. 83%, p < .001). Improvement was similar across provider types (adult vs. pediatric) and settings (community vs. academic).

Association Between Hospital-Acquired Harm Outcomes and Membership in a National Patient Safety Collaborative

IMPORTANCE

Hospital engagement networks supported by the US Centers for Medicare & Medicaid Services Partnership for Patients program have reported significant reductions in hospital-acquired harm, but methodological limitations and lack of peer review have led to persistent questions about the effectiveness of this approach.

OBJECTIVE

To evaluate associations between membership in Children's Hospitals' Solutions for Patient Safety (SPS), a federally funded hospital engagement network, and hospital-acquired harm using standardized definitions and secular trend adjustment.

DESIGN, SETTING, AND PARTICIPANTS

This prospective hospital cohort study included 99 children's hospitals. Using interrupted time series analyses with staggered intervention introduction, immediate and postimplementation changes in hospital-acquired harm rates were analyzed, with adjustment for preexisting secular trends. Outcomes were further evaluated by early-adopting (n = 73) and late-adopting (n = 26) cohorts.

EXPOSURES

Hospitals implemented harm prevention bundles, reported outcomes and bundle compliance using standard definitions to the network monthly, participated in learning events, and implemented a broad safety culture program. Hospitals received regular reports on their comparative performance.

MAIN OUTCOMES AND MEASURES

Outcomes for 8 hospital-acquired conditions were evaluated over 1 year before and 3 years after intervention.

RESULTS

In total, 99 hospitals met the inclusion criteria and were included in the analysis. A total of 73 were considered part of the early-adopting cohort (joined between 2012-2013) and 26 were considered part of the late-adopting cohort (joined between 2014-2016). A total of 42 hospitals were freestanding children's hospitals, and 57 were children's hospitals within hospital or health systems. The implementation of SPS was associated with an improvement in hospital-acquired condition rates in 3 of the 8 conditions after accounting for secular trends. Membership in the SPS was associated with an immediate reduction in central catheter-associated bloodstream infections (coefficient = -0.152; 95% CI, -0.213 to -0.019) and falls of moderate or greater severity (coefficient = -0.331; 95% CI, -0.594 to -0.069). The implementation of the SPS was associated with a reduction in the monthly rate of adverse drug events (coefficient = -0.021; 95% CI, -0.034 to -0.008) in the post-SPS period. The study team observed larger decreases for the early-adopting cohort compared with the late-adopting cohort.

CONCLUSIONS AND RELEVANCE

Through the application of rigorous methods (standard definitions and longitudinal time series analysis with adjustment for secular trends), this study provides a more thorough analysis of the association between the Partnership for Patients hospital engagement network model and reductions in hospital-acquired conditions. These findings strengthen previous claims of an association between this model and improvement. However, inconsistent observations across hospital-acquired conditions when adjusted for secular trends suggests that some caution regarding attributing all effects observed to this model is warranted.

Striving for high reliability in healthcare: a qualitative study of the implementation of a hospital safety programme

BACKGROUND

Healthcare leaders look to high-reliability organisations (HROs) for strategies to improve safety, despite questions about how to translate these strategies into practice. Weick and Sutcliffe describe five principles exhibited by HROs. Interventions aiming to foster these principles are common in healthcare; however, there have been few examinations of the perceptions of those who have planned or experienced these efforts.

OBJECTIVE

This single-site qualitative study explores how healthcare professionals understand and enact the HRO principles in response to an HRO-inspired hospital-wide safety programme.

METHODS

We interviewed 71 participants representing hospital executives, programme leadership, and staff and physicians from three clinical services. We observed and collected data from unit and hospital-wide quality and safety meetings and activities. We used thematic analysis to code and analyse the data.

RESULTS

Participants reported enactment of the HRO principles 'preoccupation with failure', 'reluctance to simplify interpretations' and 'sensitivity to operations', and described the programme as adding legitimacy, training, and support. However, the programme was more often targeted at, and taken up by, nurses compared with other groups. Participants were less able to identify interventions that supported the HRO principles 'commitment to resilience' and 'deference to expertise' and reported limited examples of changes in practices related to these principles. Moreover, we identified inconsistent, and even conflicting, understanding of concepts related to the HRO principles, often related to social and professional norms and practices. Finally, an individualised rather than systemic approach hindered collective actions underlying high reliability.

CONCLUSION

Our findings demonstrate that the safety programme supported some HRO principles more than others, and was targeted at, and perceived differently across professional groups leading to inconsistent understanding and enactments of the principles across the organisation. Combining HRO-inspired interventions with more targeted attention to each of the HRO principles could produce greater, more consistent high-reliability practices.

The perceptions of construction workers on designing a workplace nutrition intervention in the UK

 

According to the European Commission, construction is an important industry providing the EU with 18 million jobs and contributing to 9% of the EU's GDP in 2020. Construction workers struggle with healthy food choices due to lack of knowledge, long working hours, remote site locations, poor food facilities on site, and temporary accommodation. Yet, nutrition interventions in construction are rare, with no UK studies. This is an exploratory study designed to investigate workers' perceptions of a workplace intervention to facilitate healthy nutrition choices. Engaging participants in the intervention design showed positive results on behaviour change. Five internally homogenous focus groups were conducted on three different construction sites (in three companies); two with managers (n = 11) and three with workers (including subcontractors) (n = 27). Sites differed in size (14; 50-100; and 300 workers); two were temporary. Framework Analysis was used to analyse data. The main themes uncovered in the focus groups were; 1) the need for workers to learn about food to sustain good energy levels, as deemed crucial for their job 2) the desire to get an understanding about portion sizes, food labels, impacts of food on mood and practical ideas of healthy snacks and meal planning and 3) the importance of intervention accessibility for everybody on site (including subcontractors), convenient scheduling and location, and managers support to encourage participation. A participatory approach was used to explore workers' suggestions on the content and delivery of the nutrition intervention. Education and practicality of recommendations were of the essence to workers, who suggested that individual characteristics, the nature of construction jobs (e.g. busy schedules, transient jobs), and resources available (e.g. storage) need to be considered when designing the intervention. Inclusivity, accessibility and managerial support were regarded as valuable in the intervention delivery.

Key messages

This research produced recommendations to encourage the development and implementation of inclusive nutrition interventions in construction, to improve the health and wellbeing of workers. This research invites public health consultants and senior leaders in construction to invest in supporting healthy behaviours of workers, with a consideration of job and workplace characteristics.

Implementation of a central-line bundle: a qualitative study of three clinical units

Background

Evidence for the central line-associated bloodstream infection (CLABSI) bundle effectiveness remains mixed, possibly reflecting implementation challenges and persistent ambiguities in how CLABSIs are counted and bundle adherence measured. In the context of a tertiary pediatric hospital that had reduced CLABSI by 30% as part of an international safety program, we aimed to examine unit-based socio-cultural factors influencing bundle practices and measurement, and how they come to be recognized and attended to by safety leaders over time in an organization-wide bundle implementation effort.

Methods

We used an interpretivist qualitative research approach, based on 74 interviews, approximately 50 h of observations, and documents. Data collection focused on hospital executives and safety leadership, and three clinical units: a medical specialty unit, an intensive care unit, and a surgical unit. We used thematic analysis and constant comparison methods for data analysis.

Results

Participants had variable beliefs about the central-line bundle as a quality improvement priority based on their professional roles and experiences and unit setting, which influenced their responses. Nursing leaders were particularly concerned about CLABSI being one of an overwhelming number of QI targets for which they were responsible. Bundle implementation strategies were initially reliant on unit-based nurse education. Over time there was recognition of the need for centralized education and reinforcement tactics. However, these interventions achieved limited impact given the influence of competing unit workflow demands and professional roles, interactions, and routines, which were variably targeted in the safety program. The auditing process, initially a responsibility of units, was performed in different ways based on individuals’ approaches to the process. Given concerns about auditing reliability, a centralized approach was implemented, which continued to have its own variability.

Conclusions

Our findings report on a contextualized, dynamic implementation approach that required movement between centralized and unit-based approaches and from a focus on standardization to some recognition of a role for customization. However, some factors related to bundle compliance and measurement remain unaddressed, including harder to change socio-cultural factors likely important to sustainability of the CLABSI reductions and fostering further improvements across a broader safety agenda.

Interprofessional and multiprofessional approaches in quality improvement education

The imperative for all healthcare professionals to partake in quality improvement (QI) has resulted in the development of QI education programs with participants from different professional backgrounds. However, there is limited empirical and theoretical examination as to why, when and how interprofessional and multiprofessional education occurs in QI and the outcomes of these approaches. This paper reports on a qualitative collective case study of interprofessional and multiprofessional education in three longitudinal QI education programs. We conducted 58 interviews with learners, QI project coaches, program directors and institutional leads and 135 h of observations of in-class education sessions, and collected relevant documents such as course syllabi and handouts. We used an interpretive thematic analysis using a conventional and directed content analysis approach. In the directed content approach, we used sociology of professions theory with particular attention to professional socialization, hierarchies and boundaries in QI, to understand the ways in which individuals' professional backgrounds informed the planning and experiences of the QI education programs. Findings demonstrated that both interprofessional and multiprofessional education approaches were being used to achieve different education objectives. While each approach demonstrated positive learning and practice outcomes, tensions related to the different ways in which professional groups are engaging in QI, power dynamics between professional groups, and disconnects between curricula and practice existed. Further conceptual clarity is essential for a more informed discussion about interprofessional and multiprofessional education approaches in QI and explicit attention is needed to professional processes and tensions, to optimize the impact of education on practice.

Experiential Learning in Project-Based Quality Improvement Education: Questioning Assumptions and Identifying Future Directions

PURPOSE

Project-based experiential learning is a defining element of quality improvement (QI) education despite ongoing challenges and uncertainties. The authors examined stakeholders' perceptions and experiences of QI project-based learning to increase understanding of factors that influence learning and project experiences.

METHOD

The authors used a case study approach to examine QI project-based learning in 3 advanced longitudinal QI programs, 2 at the University of Toronto and 1 at an academic tertiary-care hospital. From March 2016 to June 2017, they undertook 135 hours of education program observation and 58 interviews with learners, program directors, project coaches, and institutional leaders and reviewed relevant documents. They analyzed data using a conventional and directed data analysis approach.

RESULTS

The findings provide insight into 5 key factors that influenced participants' project-based learning experiences and outcomes: (1) variable emphasis on learning versus project objectives and resulting benefits, tensions, and consequences; (2) challenges integrating the QI project into the curriculum timeline; (3) project coaching factors (e.g., ability, capacity, role clarity); (4) participants' differing access to resources and ability to direct a QI project given their professional roles; and (5) workplace environment influence on project success.

CONCLUSIONS

The findings contribute to an empirical basis toward more effective experiential learning in QI by identifying factors to target and optimize. Expanding conceptualizations of project-based learning for QI education beyond learner-initiated, time-bound projects, which are at the core of many QI educational initiatives, may be necessary to improve learning and project outcomes.

A comparison of 4 different machine learning algorithms to predict lactoferrin content in bovine milk from mid-infrared spectra

Lactoferrin (LF) is a glycoprotein naturally present in milk. Its content varies throughout lactation, but also with mastitis; therefore it is a potential additional indicator of udder health beyond somatic cell count. Condequently, there is an interest in quantifying this biomolecule routinely. First prediction equations proposed in the literature to predict the content in milk using milk mid-infrared spectrometry were built using partial least square regression (PLSR) due to the limited size of the data set. Thanks to a large data set, the current study aimed to test 4 different machine learning algorithms using a large data set comprising 6,619 records collected across different herds, breeds, and countries. The first algorithm was a PLSR, as used in past investigations. The second and third algorithms used partial least square (PLS) factors combined with a linear and polynomial support vector regression (PLS + SVR). The fourth algorithm also used PLS factors, but included in an artificial neural network with 1 hidden layer (PLS + ANN). The training and validation sets comprised 5,541 and 836 records, respectively. Even if the calibration prediction performances were the best for PLS + polynomial SVR, their validation prediction performances were the worst. The 3 other algorithms had similar validation performances. Indeed, the validation root mean squared error (RMSE) ranged between 162.17 and 166.75 mg/L of milk. However, the lower standard deviation of cross-validation RMSE and the better normality of the residual distribution observed for PLS + ANN suggest that this modeling was more suitable to predict the LF content in milk from milk mid-infrared spectra (R²v = 0.60 and validation RMSE = 162.17 mg/L of milk). This PLS +ANN model was then applied to almost 6 million spectral records. The predicted LF showed the expected relationships with milk yield, somatic cell score, somatic cell count, and stage of lactation. The model tended to underestimate high LF values (higher than 600 mg/L of milk). However, if the prediction threshold was set to 500 mg/L, 82% of samples from the validation having a content of LF higher than 600 mg/L were detected. Future research should aim to increase the number of those extremely high LF records in the calibration set.

The evolution of an asset-based community led alcohol harm intervention in the North West England

Background

Communities in Charge of Alcohol (CICA) is an Asset Based Community Development (ABCD) place-based approach to reducing alcohol harm. Local volunteers, from areas with multiple indicators of deprivation, train to become accredited 'Alcohol Health Champions' (AHCs). AHCs, supported by a local co-ordinator, provide brief opportunistic advice at an individual level and mobilise action on alcohol availability through influencing licensing decisions at a community level. CICA is the first programme we are aware of globally that has attempted to build local AHC capacity. Here we explore lessons learned from four case study areas (of the original ten) that persisted with the intervention for more than 12 months.

Methods

A case study approach to investigate the context, acceptability, facilitators and barriers to maintaining CICA. Descriptive analysis of ongoing recruitment of champions, numbers of training events and activity of champions (as reported by area coordinators). Framework analysis of interviews with AHCs and stakeholders.

Results

CICA has increased public health capacity by training 123 AHCs in its first year. The four areas that continued with CICA have trained a further 34. The different approaches in the four areas include: embedding champions in wider health champion/volunteering projects; innovative use of new technology (portable fibroscan); expansion into different geographical areas. AHCs and coordinators report significant social value from participation in CICA.

Conclusions

The likelihood of embedding CICA into a local area's activities appeared to be dependent on the energy and enthusiasm of the local area's co-ordinator, and may be dependent on that individual remaining in post. ABCD programmes may be more likely to be sustainable if capacity building is supported. CICA might be more sustainable if it was embedded in a wider programme of ABCD, since health issues are interrelated and AHCs often wish to broaden their portfolio.

Key messages

A volunteer alcohol health champions programme increased public health capacity in areas of social deprivation by utilising the assets (skills) of local people. Embedding a community alcohol health champions programme in a wider programme of asset based community development is more sustainable and allows champions to broaden their volunteering portfolio.

Ethical aspects in the use of radiation in medicine: update from ICRP Task Group 109

Whereas scientific evidence is the basis for recommendations and guidance on radiological protection, professional ethics is critically important and should always guide professional behaviour. The International Commission on Radiological Protection (ICRP) established Task Group 109 to advise medical professionals, patients, families, carers, the public, and authorities about the ethical aspects of radiological protection of patients in the diagnostic and therapeutic use of radiation in medicine. Occupational exposures and research-related exposures are not within the scope of this task group. Task Group 109 will produce a report that will be available to the different interested parties for consultation before publication. Presently, the report is at the stage of a working document that has benefitted from an international workshop organised on the topic by the World Health Organization. It presents the history of ethics in medicine in ICRP, and explains why this subject is important, and the benefits it can bring to the standard biomedical ethics. As risk is an essential part in decision-making and communication, a summary is included on what is known about the dose-effect relationship, with emphasis on the associated uncertainties. Once this theoretical framework has been presented, the report becomes resolutely more practical. First, it proposes an evaluation method to analyse specific situations from an ethical point of view. This method allows stakeholders to review a set of six ethical values and provides hints on how they could be balanced. Next, various situations (e.g. pregnancy, elderly, paediatric, end of life) are considered in two steps: first within a realistic, ethically challenging scenario on which the evaluation method is applied; and second within a more general context. Scenarios are presented and discussed with attention to specific patient circumstances, and on how and which reflections on ethical values can be of help in the decision-making process. Finally, two important related aspects are considered: how should we communicate with patients, family, and other stakeholders; and how should we incorporate ethics into the education and training of medical professionals?

Using e-cigarettes for smoking cessation: evaluation of a pilot project in the North West of England

AIMS

E-cigarettes have been advocated as an effective smoking cessation intervention, with evidence indicating that they are substantially less harmful than conventional cigarettes. As a result, a pilot to encourage people to swap from conventional cigarettes to e-cigarettes was conducted in 2018 in a socially deprived area in the North West of England. This evaluation highlights the key findings from the pilot.

METHODS

An analysis of secondary data at 4 weeks (n = 1022) was undertaken to predict those who used solely used e-cigarettes (i.e. had quit tobacco, as confirmed by a carbon monoxide test, CO < 10 ppm) from baseline characteristics, using chi-square tests and logistic regression. Baseline data were demographics, smoking levels and service provider type.

RESULTS

Of the 1022 participants who engaged with the pilot 614 were still engaged at 4 weeks, of whom 62% had quit; quitting was more likely in younger participants (aged 18-24) and less likely in those who were sick and disabled. Of those who still smoked tobacco at week 4 (n = 226), smoking had reduced from a baseline of 19.1 cigarettes/day to 8.7. Overall, 37% (381) of those initially enrolled were confirmed to be using an e-cigarette on its own at follow-up. Successful quit was associated with occupation (unemployed, 33% vs intermediate, 47%, p = .023) and residing in the less deprived quintiles of deprivation (50% vs 34% in the most deprived quintile, p = .016).

CONCLUSIONS

Making the conservative assumption that all those not in contact at 4 weeks were still smoking tobacco, for every five people entering the scheme, three people stayed on the programme and reduced their cigarette smoking and one person cut out tobacco altogether. E-cigarettes appear to be an effective nicotine replacement therapy; however, further research is required to determine whether e-cigarette users are more likely to reduce their overall nicotine consumption in the longer term.

Accelerating Improvement in Children's Healthcare Through Quality Improvement Collaboratives: A Synthesis of Recent Efforts

Purpose of review

Quality improvement collaboratives can accelerate quality improvement and patient safety efforts. We reviewed major pediatric quality improvement collaboratives that have published results in the past five years and discussed common success factors and barriers encountered by these collaboratives.

Recent Findings

Many pediatric quality improvement collaboratives are active in neonatal, cystic fibrosis, congenital heart disease, hematology/oncoogy, chronic kidney disease, rheumatology, critical care, and general pediatric care.

Summary

Factors important to the success of these pediatric quality improvement collaboratives include data sharing and communication, trust among institutions, financial support, support from national organizations, use of a theoretical framework to guide collaboration, patient and family involvement, and incentives for participation at both the individual and institutional levels. Common barriers encountered by these collaboratives include insufficient funding or resources, legal concerns, difficulty coming to consensus on best practices and outcome measures, and overcoming cultural barriers to change. Learning from the successes and challenges encountered by these collaboratives will enable the pediatric healthcare quality improvement community to continue to evolve this approach to maximize benefits to children.

"All the ward's a stage": a qualitative study of the experience of direct observation of handoffs

Direct observation of clinical skills is central to assessment in a competency-based medical education model, yet little is known about how direct observation is experienced by trainees and observers. The objective of the study is to explore how direct observation was experienced by residents and faculty in the context of the I-PASS Handoff Study. In this multi-center qualitative study, we conducted focus groups and semi-structured interviews of residents and faculty members at eight tertiary pediatric centers in North America that implemented the I-PASS Handoff Bundle. We employed qualitative thematic analysis to interpret the data. Barriers to and strategies for direct observation were described relating to the observer, trainee, and clinical environment. Residents and faculty described a mutual awareness that residents change their performance of handoffs when observed, in contrast to their usual behavior in a clinical setting. Changes in handoff performance may depend on the nature of the observer or 'audience'. Direct observation also highlighted the importance of handoffs to participants, recognized as a clinical activity that warrants feedback and assessment. Dramaturgical theory can be used to understand our finding of 'front-stage' (observed) versus 'backstage' (unobserved) handoffs as distinct performances, tailored to an "audience". Educators must be cognizant of changes in performance of routine clinical activities when using direct observation to assess clinical competence.

Patient safety after implementation of a coproduced family centered communication programme: multicenter before and after intervention study

OBJECTIVE

To determine whether medical errors, family experience, and communication processes improved after implementation of an intervention to standardize the structure of healthcare provider-family communication on family centered rounds.

DESIGN

Prospective, multicenter before and after intervention study.

SETTING

Pediatric inpatient units in seven North American hospitals, 17 December 2014 to 3 January 2017.

PARTICIPANTS

All patients admitted to study units (3106 admissions, 13171 patient days); 2148 parents or caregivers, 435 nurses, 203 medical students, and 586 residents.

INTERVENTION

Families, nurses, and physicians coproduced an intervention to standardize healthcare provider-family communication on ward rounds ("family centered rounds"), which included structured, high reliability communication on bedside rounds emphasizing health literacy, family engagement, and bidirectional communication; structured, written real-time summaries of rounds; a formal training programme for healthcare providers; and strategies to support teamwork, implementation, and process improvement.

MAIN OUTCOME MEASURES

Medical errors (primary outcome), including harmful errors (preventable adverse events) and non-harmful errors, modeled using Poisson regression and generalized estimating equations clustered by site; family experience; and communication processes (eg, family engagement on rounds). Errors were measured via an established systematic surveillance methodology including family safety reporting.

RESULTS

The overall rate of medical errors (per 1000 patient days) was unchanged (41.2 (95% confidence interval 31.2 to 54.5) pre-intervention v 35.8 (26.9 to 47.7) post-intervention, P=0.21), but harmful errors (preventable adverse events) decreased by 37.9% (20.7 (15.3 to 28.1) v 12.9 (8.9 to 18.6), P=0.01) post-intervention. Non-preventable adverse events also decreased (12.6 (8.9 to 17.9) v 5.2 (3.1 to 8.8), P=0.003). Top box (eg, "excellent") ratings for six of 25 components of family reported experience improved; none worsened. Family centered rounds occurred more frequently (72.2% (53.5% to 85.4%) v 82.8% (64.9% to 92.6%), P=0.02). Family engagement 55.6% (32.9% to 76.2%) v 66.7% (43.0% to 84.1%), P=0.04) and nurse engagement (20.4% (7.0% to 46.6%) v 35.5% (17.0% to 59.6%), P=0.03) on rounds improved. Families expressing concerns at the start of rounds (18.2% (5.6% to 45.3%) v 37.7% (17.6% to 63.3%), P=0.03) and reading back plans (4.7% (0.7% to 25.2%) v 26.5% (12.7% to 7.3%), P=0.02) increased. Trainee teaching and the duration of rounds did not change significantly.

CONCLUSIONS

Although overall errors were unchanged, harmful medical errors decreased and family experience and communication processes improved after implementation of a structured communication intervention for family centered rounds coproduced by families, nurses, and physicians. Family centered care processes may improve safety and quality of care without negatively impacting teaching or duration of rounds.

Genome-wide association analyses based on a multiple-trait approach for modeling feed efficiency

Genome-wide association (GWA) of feed efficiency (FE) could help target important genomic regions influencing FE. Data provided by an international dairy FE research consortium consisted of phenotypic records on dry matter intakes (DMI), milk energy (MILKE), and metabolic body weight (MBW) on 6,937 cows from 16 stations in 4 counties. Of these cows, 4,916 had genotypes on 57,347 single nucleotide polymorphism (SNP) markers. We compared a GWA analysis based on the more classical residual feed intake (RFI) model with one based on a previously proposed multiple trait (MT) approach for modeling FE using an alternative measure (DMI|MILKE,MBW). Both models were based on a single-step genomic BLUP procedure that allowed the use of phenotypes from both genotyped and nongenotyped cows. Estimated effects for single SNP markers were small and not statistically important but virtually identical for either FE measure (RFI vs. DMI|MILKE,MBW). However, upon further refining this analysis to develop joint tests within nonoverlapping 1-Mb windows, significant associations were detected between either measure of FE with a window on each of Bos taurus autosomes BTA12 and BTA26. There was, as expected, no overlap between detected genomic regions for DMI|MILKE,MBW and genomic regions influencing the energy sink traits (i.e., MILKE and MBW) because of orthogonal relationships clearly defined between the various traits. Conversely, GWA inferences on DMI can be demonstrated to be partly driven by genetic associations between DMI with these same energy sink traits, thereby having clear implications when comparing GWA studies on DMI to GWA studies on FE-like measures such as RFI.

Oncolytic reovirus therapy: Pilot study in dogs with spontaneously occurring tumours

Oncolytic virotherapy is a novel treatment involving replication-competent virus in the elimination of cancer. We have previously reported the oncolytic effects of reovirus in various canine cancer cell lines. This study aims to establish the safety profile of reovirus in dogs with spontaneously occurring tumours and to determine a recommended dosing regimen. Nineteen dogs with various tumours, mostly of advanced stages, were treated with reovirus, ranging from 1.0 × 10⁸ to 5.0 × 10⁹ TCID₅₀ given as intratumour injection (IT) or intravenous infusion (IV) daily for up to 5 consecutive days in 1 or multiple treatment cycles. Adverse events (AEs) were graded according to the Veterinary Cooperative Oncology Group- Common Terminology Criteria for Adverse Events (VCOG-CTCAE) v1.1 guidelines. Viral shedding, neutralizing anti-reovirus antibody (NARA) production and immunohistochemical (IHC) detection of reovirus protein in the tumours were also assessed. AE was not observed in most dogs and events were limited to Grade I or II fever, vomiting, diarrhoea and inflammation of the injected tumour. No infectious virus was shed and all dogs had elevated NARA levels post-treatment. Although IHC results were only available in 6 dogs, 4 were detected positive for reovirus protein. In conclusion, reovirus is well-tolerated and can be given safely to tumour-bearing dogs according to the dosing regimen used in this study without significant concerns of viral shedding. Reovirus is also potentially effective in various types of canine tumours.

Concepts, models and measurement of continuity of care in mental health services: A systematic appraisal of the literature

WHAT IS KNOWN ON THE SUBJECT?: Care continuity is considered to be a cornerstone of modern mental health care. As community mental health services have become increasingly fragmented and complex, the crucial criterion for best quality care has become the degree to which treatment delivered by separate services and professionals is continuous and well coordinated. However, clarification of the key elements of continuity has proved challenging and a consensus has not been reached. Recent research has shown significant levels of variation in the quality of care coordination across England and Wales, with potentially detrimental consequences for individuals. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: Studies on care continuity identified in this review are grouped into three categories: studies defining concepts of care continuity, studies providing models of continuity and studies describing development of questionnaires about care continuity. There are many similarities and parallels between concepts of continuity described in the studies under review. Therefore, there is potential for developing a consensus on the nature of care continuity as a multidimensional concept. The priority placed upon the patient's experience of care continuity is identified as a major focus in these studies. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: A consensus on the nature of care continuity would benefit both theory and practice in mental health nursing. It would provide a firmer foundation for new research seeking to improve continuity for people using services, and enable mental health nurses working as care coordinators to have a better understanding of the elements of their role that are most effective.

ABSTRACT

Introduction The increased complexity of community mental health services, and associated fragmentation of traditional dividing lines between services, has underscored the centrality of care continuity and coordination in modern mental health care. However, clarification of the key features of the care continuity concept has proved difficult and a consensus has not been reached. Aim/Question This review draws together and critically examines latest evidence concerning concepts, models and scales based on a multidimensional understanding of care continuity. Method Databases ASSIA, PubMed, MEDLINE and Cochrane were searched for papers dating from January 2005 to July 2016, of which 21 articles met the inclusion criteria. These were subjected to quality appraisal based on CASP and COSMIN checklists. Studies were grouped into three thematic categories describing concepts, models and scales of care continuity. Results/Discussion Synthesis indicated correspondence between independent, multidimensional models of care continuity, providing greater clarity regarding the essential features of the concept. Association, although not causation, between care continuity factors and health outcomes is supported by current evidence. Implications for practice Clarification of care continuity in mental health services may enable nurses working as care coordinators to develop a better understanding of key elements of their role, and provide guidance for future service development.

Parent Preferences for Medical Error Disclosure: A Qualitative Study

OBJECTIVE

According to disclosure guidelines, patients experiencing adverse events due to medical errors should be offered full disclosure, whereas disclosure of near misses is not traditionally expected. This may conflict with parental expectations; surveys reveal most parents expect full disclosure whether errors resulted in harm or not. Protocols regarding whether to include children in these discussions have not been established. This study explores parent preferences around disclosure and views on including children.

METHODS

Fifteen parents of hospitalized children participated in semistructured interviews. Three hypothetical scenarios of different severity were used to initiate discussion. Interviews were audiotaped, transcribed, and coded for emergent themes.

RESULTS

Parents uniformly wanted disclosure if harm occurred, although fewer wanted their child informed. For nonharmful errors, most parents wanted disclosure for themselves but few for their children.With respect to including children in disclosure, parents preferred to assess their children's cognitive and emotional readiness to cope with disclosure, wishing to act as a "buffer" between the health care team and their children. Generally, as event severity decreased, they felt that risks of informing children outweighed benefits. Parents strongly emphasized needing reassurance of a good final outcome and anticipated difficulty managing their emotions.

CONCLUSIONS

Parents have mixed expectations regarding disclosure. Although survey studies indicate a stronger desire for disclosure of nonharmful events than for adult patients, this qualitative study revealed a greater degree of hesitation and complexity. Parents have a great need for reassurance and consistently wish to act as a buffer between the health care team and their children.

Resident Experiences With Implementation of the I-PASS Handoff Bundle

BACKGROUND

The I-PASS Handoff Study found that introduction of a handoff bundle (handoff and teamwork training for residents, a mnemonic, a handoff tool, a faculty development program, and a sustainability campaign) at 9 pediatrics residency programs was associated with improved communication and patient safety.

OBJECTIVE

This parallel qualitative study aimed to understand resident experiences with I-PASS and to inform future implementation and sustainability strategies.

METHODS

Resident experiences with I-PASS were explored in focus groups (N = 50 residents) at 8 hospitals throughout 2012-2013. A content analysis of transcripts was conducted following the principles of grounded theory.

RESULTS

Residents generally accepted I-PASS as an ideal format for handoffs, and valued learning a structured approach. Across all sites, residents reported full adherence to I-PASS when observed, but selective adherence in usual practice. Residents adhered more closely when patients were complex, teams were unfamiliar, and during evening handoff. Residents reported using elements of the I-PASS mnemonic variably, with Illness Severity and Action Items most consistently used, but Synthesis by Receiver least used, except when observed. Most residents were receptive to the electronic handoff tool, but perceptions about usability varied across sites. Experiences with observation and feedback were mixed. Concern about efficiency commonly influenced attitudes about I-PASS.

CONCLUSIONS

Residents generally supported I-PASS implementation, but adherence was influenced by patient type, context, and individual and team factors. Our findings could inform future implementation, particularly around the areas of resident engagement in change, sensitivity to resident level, perceived efficiency, and faculty observation.

Families as Partners in Hospital Error and Adverse Event Surveillance

Importance

Medical errors and adverse events (AEs) are common among hospitalized children. While clinician reports are the foundation of operational hospital safety surveillance and a key component of multifaceted research surveillance, patient and family reports are not routinely gathered. We hypothesized that a novel family-reporting mechanism would improve incident detection.

Objective

To compare error and AE rates (1) gathered systematically with vs without family reporting, (2) reported by families vs clinicians, and (3) reported by families vs hospital incident reports.

Design, Setting, and Participants

We conducted a prospective cohort study including the parents/caregivers of 989 hospitalized patients 17 years and younger (total 3902 patient-days) and their clinicians from December 2014 to July 2015 in 4 US pediatric centers. Clinician abstractors identified potential errors and AEs by reviewing medical records, hospital incident reports, and clinician reports as well as weekly and discharge Family Safety Interviews (FSIs). Two physicians reviewed and independently categorized all incidents, rating severity and preventability (agreement, 68%-90%; κ, 0.50-0.68). Discordant categorizations were reconciled. Rates were generated using Poisson regression estimated via generalized estimating equations to account for repeated measures on the same patient.

Main Outcomes and Measures

Error and AE rates.

Results

Overall, 746 parents/caregivers consented for the study. Of these, 717 completed FSIs. Their median (interquartile range) age was 32.5 (26-40) years; 380 (53.0%) were nonwhite, 566 (78.9%) were female, 603 (84.1%) were English speaking, and 380 (53.0%) had attended college. Of 717 parents/caregivers completing FSIs, 185 (25.8%) reported a total of 255 incidents, which were classified as 132 safety concerns (51.8%), 102 nonsafety-related quality concerns (40.0%), and 21 other concerns (8.2%). These included 22 preventable AEs (8.6%), 17 nonharmful medical errors (6.7%), and 11 nonpreventable AEs (4.3%) on the study unit. In total, 179 errors and 113 AEs were identified from all sources. Family reports included 8 otherwise unidentified AEs, including 7 preventable AEs. Error rates with family reporting (45.9 per 1000 patient-days) were 1.2-fold (95% CI, 1.1-1.2) higher than rates without family reporting (39.7 per 1000 patient-days). Adverse event rates with family reporting (28.7 per 1000 patient-days) were 1.1-fold (95% CI, 1.0-1.2; P = .006) higher than rates without (26.1 per 1000 patient-days). Families and clinicians reported similar rates of errors (10.0 vs 12.8 per 1000 patient-days; relative rate, 0.8; 95% CI, .5-1.2) and AEs (8.5 vs 6.2 per 1000 patient-days; relative rate, 1.4; 95% CI, 0.8-2.2). Family-reported error rates were 5.0-fold (95% CI, 1.9-13.0) higher and AE rates 2.9-fold (95% CI, 1.2-6.7) higher than hospital incident report rates.

Conclusions and Relevance

Families provide unique information about hospital safety and should be included in hospital safety surveillance in order to facilitate better design and assessment of interventions to improve safety.

Learning Through Experience: Influence of Formal and Informal Training on Medical Error Disclosure Skills in Residents

BACKGROUND

Residents' attitudes toward error disclosure have improved over time. It is unclear whether this has been accompanied by improvements in disclosure skills.

OBJECTIVE

To measure the disclosure skills of internal medicine (IM), paediatrics, and orthopaedic surgery residents, and to explore resident perceptions of formal versus informal training in preparing them for disclosure in real-world practice.

METHODS

We assessed residents' error disclosure skills using a structured role play with a standardized patient in 2012-2013. We compared disclosure skills across programs using analysis of variance. We conducted a multiple linear regression, including data from a historical cohort of IM residents from 2005, to investigate the influence of predictor variables on performance: training program, cohort year, and prior disclosure training and experience. We conducted a qualitative descriptive analysis of data from semistructured interviews with residents to explore resident perceptions of formal versus informal disclosure training.

RESULTS

In a comparison of disclosure skills for 49 residents, there was no difference in overall performance across specialties (4.1 to 4.4 of 5, P = .19). In regression analysis, only the current cohort was significantly associated with skill: current residents performed better than a historical cohort of 42 IM residents (P < .001). Qualitative analysis identified the importance of both formal (workshops, morbidity and mortality rounds) and informal (role modeling, debriefing) activities in preparation for disclosure in real-world practice.

CONCLUSIONS

Residents across specialties have similar skills in disclosure of errors. Residents identified role modeling and a strong local patient safety culture as key facilitators for disclosure.

Use of genotype × environment interaction model to accommodate genetic heterogeneity for residual feed intake, dry matter intake, net energy in milk, and metabolic body weight in dairy cattle

Feed efficiency in dairy cattle has gained much attention recently. Due to the cost-prohibitive measurement of individual feed intakes, combining data from multiple countries is often necessary to ensure an adequate reference population. It may then be essential to model genetic heterogeneity when making inferences about feed efficiency or selecting efficient cattle using genomic information. In this study, we constructed a marker × environment interaction model that decomposed marker effects into main effects and interaction components that were specific to each environment. We compared environment-specific variance component estimates and prediction accuracies from the interaction model analyses, an across-environment analyses ignoring population stratification, and a within-environment analyses using an international feed efficiency data set. Phenotypes included residual feed intake, dry matter intake, net energy in milk, and metabolic body weight from 3,656 cows measured in 3 broadly defined environments: North America (NAM), the Netherlands (NLD), and Scotland (SAC). Genotypic data included 57,574 single nucleotide polymorphisms per animal. The interaction model gave the highest prediction accuracy for metabolic body weight, which had the largest estimated heritabilities ranging from 0.37 to 0.55. The within-environment model performed the best when predicting residual feed intake, which had the lowest estimated heritabilities ranging from 0.13 to 0.41. For traits (dry matter intake and net energy in milk) with intermediate estimated heritabilities (0.21 to 0.50 and 0.17 to 0.53, respectively), performance of the 3 models was comparable. Genomic correlations between environments also were computed using variance component estimates from the interaction model. Averaged across all traits, genomic correlations were highest between NAM and NLD, and lowest between NAM and SAC. In conclusion, the interaction model provided a novel way to evaluate traits measured in multiple environments in which genetic heterogeneity may exist. This model allowed estimation of environment-specific parameters and provided genomic predictions that approached or exceeded the accuracy of competing within- or across-environment models.

Prime-boost using separate oncolytic viruses in combination with checkpoint blockade improves anti-tumour therapy

The anti-tumour effects associated with oncolytic virus therapy are mediated significantly through immune-mediated mechanisms, which depend both on the type of virus and the route of delivery. Here, we show that intra-tumoral oncolysis by Reovirus induced the priming of a CD8+, Th1-type anti-tumour response. By contrast, systemically delivered Vesicular Stomatitis Virus expressing a cDNA library of melanoma antigens (VSV-ASMEL) promoted a potent anti-tumour CD4+ Th17 response. Therefore, we hypothesised that combining the Reovirus-induced CD8+ T cell response, with the VSV-ASMEL CD4+ Th17 helper response, would produce enhanced anti-tumour activity. Consistent with this, priming with intra-tumoral Reovirus, followed by an intra-venous VSV-ASMEL Th17 boost, significantly improved survival of mice bearing established subcutaneous B16 melanoma tumours. We also show that combination of either therapy alone with anti-PD-1 immune checkpoint blockade augmented both the Th1 response induced by systemically delivered Reovirus in combination with GM-CSF, and also the Th17 response induced by VSV-ASMEL. Significantly, anti-PD-1 also uncovered an anti-tumour Th1 response following VSV-ASMEL treatment that was not seen in the absence of checkpoint blockade. Finally, the combination of all three treatments (priming with systemically delivered Reovirus, followed by double boosting with systemic VSV-ASMEL and anti-PD-1) significantly enhanced survival, with long-term cures, compared to any individual, or double, combination therapies, associated with strong Th1 and Th17 responses to tumour antigens. Our data show that it is possible to generate fully systemic, highly effective anti-tumour immunovirotherapy by combining oncolytic viruses, along with immune checkpoint blockade, to induce complementary mechanisms of anti-tumour immune responses.

Modeling genetic and nongenetic variation of feed efficiency and its partial relationships between component traits as a function of management and environmental factors

Feed efficiency (FE), characterized as the fraction of feed nutrients converted into salable milk or meat, is of increasing economic importance in the dairy industry. We conjecture that FE is a complex trait whose variation and relationships or partial efficiencies (PE) involving the conversion of dry matter intake to milk energy and metabolic body weight may be highly heterogeneous across environments or management scenarios. In this study, a hierarchical Bayesian multivariate mixed model was proposed to jointly infer upon such heterogeneity at both genetic and nongenetic levels on PE and variance components (VC). The heterogeneity was modeled by embedding mixed effects specifications on PE and VC in addition to those directly specified on the component traits. We validated the model by simulation and applied it to a joint analysis of a dairy FE consortium data set with 5,088 Holstein cows from 13 research stations in Canada, the Netherlands, the United Kingdom, and the United States. Although no differences were detected among research stations for PE at the genetic level, some evidence was found of heterogeneity in residual PE. Furthermore, substantial heterogeneity in VC across stations, parities, and ration was observed with heritability estimates of FE ranging from 0.16 to 0.46 across stations.

Patient disclosure of medical errors in paediatrics: A systematic literature review

Medical errors are common within paediatrics; however, little research has examined the process of disclosing medical errors in paediatric settings. The present systematic review of current research and policy initiatives examined evidence regarding the disclosure of medical errors involving paediatric patients. Peer-reviewed research from a range of scientific journals from the past 10 years is presented, and an overview of Canadian and international policies regarding disclosure in paediatric settings are provided. The purpose of the present review was to scope the existing literature and policy, and to synthesize findings into an integrated and accessible report. Future research priorities and policy implications are then identified.
