Building a Program Theory of Implementation Using Process Evaluation of a Complex Quality Improvement Trial in Nursing Homes

BACKGROUND AND OBJECTIVES

Significant quality problems exist in long-term care (LTC). Interventions to improve care are complex and often have limited success. Implementation remains a black box. We developed a program theory explaining how implementation of a complex intervention occurs in LTC settings-examining mechanisms of impact, effects of context on implementation, and implementation outcomes such as fidelity.

RESEARCH DESIGN AND METHODS

Concurrent process evaluation of Safer Care for Older Persons in residential Environments (SCOPE)-a frontline worker (care aide) led improvement trial in 31 Canadian LTC homes. Using a mixed-methods exploratory sequential design, qualitative data were analyzed using grounded theory to develop a conceptual model illustrating how teams implemented the intervention and how it produced change. Quantitative analyses (mixed-effects regression) tested aspects of the program theory.

RESULTS

Implementation fidelity was moderate. Implementation is facilitated by (a) care aide engagement with core intervention components; (b) supportive leadership (internal facilitation) to create positive team dynamics and help negotiate competing workplace priorities; (c) shifts in care aide role perceptions and power differentials. Mixed-effects model results suggest intervention acceptability, perceived intervention benefits, and leadership support predict implementation fidelity. When leadership support is high, fidelity is high regardless of intervention acceptability or perceived benefits.

DISCUSSION AND IMPLICATIONS

Our program theory addresses important knowledge gaps regarding implementation of complex interventions in nursing homes. Results can guide scaling of complex interventions and future research.

Changes in Health and Well-Being of Care Aides in Nursing Homes From a Pre-Pandemic Baseline in February 2020 to December 2021

Nursing homes were profoundly affected by the COVID-19 pandemic, influencing work outcomes of care aides who provide the most direct care. We compared care aides' quality of work life by conducting a repeated cross-sectional analysis of data collected in February 2020 and December 2021 from a stratified random sample of urban nursing homes in two Canadian provinces. We used two-level random-intercept repeated-measures regression models, adjusting for demographics and nursing home characteristics. 2348 and 1116 care aides completed the survey in February 2020 and December 2021, respectively. The 2021 sample had higher odds of reporting worked short-staffed daily to weekly in the previous month than the 2020 sample. The 2021 sample also had a small but significant drop in professional efficacy and mental health. Despite the worsening changes, our findings suggest that this workforce may have withstood the pandemic better than might be expected.

Nursing assistants' use of best practices and pain in older adults living in nursing homes

BACKGROUND

Inadequate pain management persists in nursing homes. Nursing assistants provide the most direct care in nursing homes, and significantly improving the quality of care requires their adoption of best care practices informed by the best available evidence. We assessed the association between nursing assistants' use of best practices and residents' pain levels.

METHODS

We performed a cross-sectional analysis of data collected between September 2019 and February 2020 from a stratified random sample of 87 urban nursing homes in western Canada. We linked administrative data (the Resident Assessment Instrument-Minimum Data Set [RAI-MDS], 2.0) for 10,093 residents and survey data for 3547 nursing assistants (response rate: 74.2%) at the care unit level. Outcome of interest was residents' pain level, measured by the pain scale derived from RAI-MDS, 2.0. The exposure variable was nursing assistants' use of best practices, measured with validated self-report scales and aggregated to the unit level. Two-level random-intercept multinomial logistic regression accounted for the clustering effect of residents within care units. Covariates included resident demographics and clinical characteristics and characteristics of nursing assistants, unit, and nursing home.

RESULTS

Of the residents, 3305 (30.3%) were identified as having pain. On resident care units with higher levels of best practice use among nursing assistants, residents had 32% higher odds of having mild pain (odds ratio, 1.32; 95% confidence interval, 1.01-1.71; p = 0.040), compared with residents on care units with lower levels of best practice use among nursing assistants. The care units did not differ in reported moderate or severe pain among residents.

CONCLUSIONS

We observed that higher unit-level best practice use among nursing assistants was associated with mild resident pain. This association warrants further research to identify key individual and organizational factors that promote effective pain assessment and management.

Safer Care for Older Persons in (residential) Environments (SCOPE): a pragmatic controlled trial of a care aide-led quality improvement intervention

BACKGROUND

The increased complexity of residents and increased needs for care in long-term care (LTC) have not been met with increased staffing. There remains a need to improve the quality of care for residents. Care aides, providers of the bulk of direct care, are well placed to contribute to quality improvement efforts but are often excluded from so doing. This study examined the effect of a facilitation intervention enabling care aides to lead quality improvement efforts and improve the use of evidence-informed best practices. The eventual goal was to improve both the quality of care for older residents in LTC homes and the engagement and empowerment of care aides in leading quality improvement efforts.

METHODS

Intervention teams participated in a year-long facilitative intervention which supported care aide-led teams to test changes in care provision to residents using a combination of networking and QI education meetings, and quality advisor and senior leader support. This was a controlled trial with random selection of intervention clinical care units matched 1:1 post hoc with control units. The primary outcome, between group change in conceptual research use (CRU), was supplemented by secondary staff- and resident-level outcome measures. A power calculation based upon pilot data effect sizes resulted in a sample size of 25 intervention sites.

RESULTS

The final sample included 32 intervention care units matched to 32 units in the control group. In an adjusted model, there was no statistically significant difference between intervention and control units for CRU or in secondary staff outcomes. Compared to baseline, resident-adjusted pain scores were statistically significantly reduced (less pain) in the intervention group (p=0.02). The level of resident dependency significantly decreased statistically for residents whose teams addressed mobility (p<0.0001) compared to baseline.

CONCLUSIONS

The Safer Care for Older Persons in (residential) Environments (SCOPE) intervention resulted in a smaller change in its primary outcome than initially expected resulting in a study underpowered to detect a difference. These findings should inform sample size calculations of future studies of this nature if using similar outcome measures. This study highlights the problem with measures drawn from current LTC databases to capture change in this population. Importantly, findings from the trial's concurrent process evaluation provide important insights into interpretation of main trial data, highlight the need for such evaluations of complex trials, and suggest the need to consider more broadly what constitutes "success" in complex interventions.

ORGANIZATIONAL CONTEXT'S EFFECT ON CARE AIDES' PSYCHOLOGICAL EMPOWERMENT IN WESTERN CANADA

This quantitative cross-sectional sub project investigated the effects of organizational context and individual characteristics on psychological empowerment of care aides working in nursing homes. We analyzed data collected from 3765 care aides from 91 nursing homes across Western Canada between 09/2019 and 03/2020. From the random-intercept mixed effects regression models we identified significant predictors at different levels for each component of psychological empowerment. At the organizational outer context level: region and home ownership model. At the inner context (care unit) level: formal interactions (β=-0.07, p=0.03; competence), evaluation (β=0.20, p<0.02; self-determination), culture (β=0.20, p<0.02; self-determination), communication (β=0.16, p<0.001; self-determination), and social capital (β=0.22, p=0.01; impact). At the individual level: care aides’ sex, language and job satisfaction.These findings suggest important ways in which contextual elements may influence staff quality of work life characteristics and underscore the need to consider context operating at different levels, as well as consider individual and contextual interaction.

ORGANIZATIONAL CONTEXT AND QUALITY INDICATORS IN NURSING HOMES: A MICROSYSTEM LOOK

This cross-sectional quantitative sub-project assessed the association of organizational context (modifiable elements of work environments) with quality indicators (QIs) at the clinical microsystem (care unit) level. We used TREC data collected 09/2019-03/2020. The sample included 285 care units within 91 Western Canadian nursing homes. Outcomes included thirteen practice-sensitive QIs derived from the Minimum Data Set 2.0. Results from random-intercept logistic regression for each dichotomized QI showed that higher unit-aggregated scores on contextual elements as identified by the Alberta Context Tool, specifically care aide participation in decision-making (OR=3.7-8.4, p<.05), care aide perceived staffing (OR=2.6, p<.05) and time for completing tasks (OR=5.1-7.0, p<.05), and care aide rated unit-level leadership (OR=20.1, p<.05), were associated with a better unit-level performance on delirium symptoms, indwelling catheter use, behavioral symptoms, pain, and late-loss physical function. The findings suggest that targeting modifiable contextual elements is an important avenue for quality improvement interventions in nursing homes.

SUPPORTING NURSING HOME MANAGERS TO ACT ON PERFORMANCE FEEDBACK DATA: A PROVINCEWIDE IMPLEMENTATION

INFORM (Improving Nursing home care through Feedback on perfoRMance data) is a tested research intervention targeting care managers that demonstrated positive two year follow up results and has subsequently been shaped into an operationally acceptable “implementation package”. This package or innovation is being scaled up in one Canadian province’s total Long-Term-Care (LTC) home population with in depth process evaluation during the first cohort of LTC homes. This evaluation will, among other things, assess sector needs for adaptation (vs fidelity). At its core INFORM is designed to address managers’ learning needs with respect to using data to make positive change in a continuous learning loop. We will discuss the transformation of a research intervention to a sector innovation and report on interim process evaluation results.

The Influence of Context on Implementation and Improvement: Protocol for a Mixed Methods, Secondary Analyses Study

Background

Caring for the well-being of older adults is one of the greatest challenges in modern societies. Improving the quality of care and life for older adults and the work lives of their care providers calls for effective knowledge translation of evidence-based best practices.

Objective

This study’s purpose is to contribute to knowledge translation by better understanding the roles of organizational context (workplace environment) and facilitation (process or role) in implementation and improvement success. Our study has 2 goals: (1) to advance knowledge translation science by further developing and testing the Promoting Action on Research Implementation in Health Services framework (which outlines how implementation relies on the interplay of context, facilitation, and evidence) and (2) to advance research by optimizing implementation success via tailoring of modifiable elements of organizational context and facilitation.

Methods

This is secondary analyses of 15 years of longitudinal data from the Translating Research in Elder Care (TREC) program’s multiple data sources. This research is ongoing in long-term care (LTC) homes in western Canada. TREC data include the following: 5 waves of survey collection, 2 clinical trials, and regular ongoing outcome data for LTC residents. We will use a sequential exploratory and confirmatory mixed methods design. We will analyze qualitative and quantitative data holdings in an iterative process: (1) comprehensive reanalysis of qualitative data to derive hypotheses, (2) quantitative modeling to test hypotheses, and (3) action cycles to further refine and integrate qualitative and quantitative analyses. The research team includes 4 stakeholder panels: (1) system decision- and policy makers, (2) care home managers, (3) direct care staff, and (4) a citizen engagement group of people living with dementia and family members of LTC residents. A fifth group is our panel of external scientific advisors. Each panel will engage periodically, providing their perspectives on project direction and findings.

Results

This study is funded by the Canadian Institutes of Health Research. Ethics approval was obtained from the University of Alberta (Pro00096541). The results of the secondary analyses are expected by the end of 2023.

Conclusions

The project will advance knowledge translation science by deepening our understanding of the roles of context, the interactions between context and facilitation, and their influence on resident and staff quality outcomes. Importantly, findings will inform understanding of the mechanisms by which context and facilitation affect the success of implementation and offer insights into factors that influence the implementation success of interventions in nursing homes.

Transdiagnostic cognitive-behavioral group therapy for anxiety disorders: Therapists’ perception of group management in community-based care

Introduction

Cognitive-behavioral therapy (CBT) is recognized as an effective treatment for anxiety disorders. Transdiagnostic group CBT (tCBT) targets cognitive and behavioural intervention strategies common to anxiety disorders. tCBT allows the treatment of a larger number of patients simultaneously and therapists only need to master a single intervention protocol. However, tCBT may present several challenges for therapists, particularly regarding group management.

Objectives

To explore therapists’ perceptions and experience of group management during tCBT for mixed anxiety disorders.

Methods

A qualitative study embedded in a randomized controlled trial of group tCBT (Roberge & Provencher; CIHR, 2015-2021). Semi-structured interviews were conducted with 18 of the 21 therapists to document their perceptions and to identify improvements for tCBT delivery. The data were analyzed using a deductive approach and based on the interactive cyclical process of data reduction, display and conclusion drawing.

Results

Therapists raised the challenge of the heterogeneous characteristics of participants’ anxious profile, since they had to be creative to provide exercises that were suitable for a whole group. Exposure exercises, a key component of tCBT, were particularly affected by the composition of the groups. Previous group animation experience and the ability to establish a therapeutic alliance from a group perspective were important facilitators. Co-therapy also facilitated the intervention, since it allowed the therapists to be more vigilant to group dynamics and favored the organization of tCBT.

Conclusions

This study highlights the importance of exploring therapists’ perceptions and experience about group management in order to identify facilitators and barriers of group tCBT in community-based care.

Panic Disorder Severity Scale self-report: transcultural validation and sensitivity to change of the French-Canadian adaptation

Introduction

The self-report version of the Panic Disorder Severity Scale (PDSS-SR) is a reliable and valid instrument to assess panic disorder, but is unavailable in French.

Objectives

The aim of this study was to conduct a transcultural validation of the French-Canadian PDSS-SR and examine its psychometric properties.

Methods

This study is part of a pragmatic RCT of group transdiagnostic CBT for anxiety disorders, and includes 272 adults meeting DSM-5 panic disorder diagnostic criteria. At baseline, participants completed the Anxiety and Related Disorders Interview Schedule (ADIS-5), the French-Canadian PDSS-SR and self-report measures. Convergent validity was assessed with Spearman correlations, Cronbach’s α was used to analyse internal consistency, and confirmatory factor analysis (CFA) evaluated its factor structure. Sensitivity to change was assessed with paired sample t-tests in patients (n = 72) meeting DSM-5 criteria for panic disorder at baseline with posttreatment data.

Results

108 patients met DSM-5 criteria for panic disorder, including 58 with agoraphobia. The majority were women (85.3%) and mean age was 37.1 (SD = 12.4). Internal consistency (Cronbach’s α) was 0.91. For convergent validity, the highest correlation was with the Beck Anxiety Inventory (r = 0.64). CFA suggested a two-factor model. Optimal threshold for probable diagnosis was 10. Analyses support sensitivity to change when comparing transdiagnostic group CBT and control conditions.

Conclusions

With its good psychometric properties in primary care patients, the French-Canadian self-report version of the Panic Disorder Severity Scale is an efficient and practical instrument for both clinicians and researchers working in the field of mental health.

0473 The impact on treatment adherence of adding a bedpartner to CBT-I: preliminary findings from a randomised controlled trial (Project REST)

Introduction

Cognitive Behavioural Therapy for Insomnia (CBT-I) includes often difficult-to-implement behavioural change, and this can result in poor adherence to treatment recommendations. In other CBTs, adding a significant other to “individual” therapy increases adherence. Here, we report preliminary findings from a randomised controlled trial (RCT) of a newly developed partner-assisted CBT-I.

Methods

117 adults with DSM-5 Insomnia Disorder (age M±SD=47.9±15.3yrs; 73F) and their live-in partners participated in a single-blind parallel RCT. They were assigned 1:1:1 to 7wk individual CBT-I (Ind-CBTI), partner-assisted CBT-I (PA-CBTI), or sleep management control (CTRL) conditions. Participants completed daily sleep diary throughout the intervention. Adherence in CBT-I conditions was assessed for Sleep Restriction Therapy (deviation from bed and wake times, naps) and Stimulus Control Therapy (wake time-in-bed during daytime, overnight, and after final morning awakening). Intention-to-treat, mixed effects models examined differences in adherence for “Build” (initial phase to build sleep debt) and “Maintain” (starting the first week when sleep opportunity was titrated upwards) stages of therapy.

Results

All conditions showed significant increase in sleep efficiency (p&lt;.001), with significantly faster increase in Ind-CBTI and PA-CBTI compared to CTRL (ps&lt;.001). Sleep Restriction Therapy: Build stage (vs Maintain) had greater adherence to prescribed wake time (p=.045); Condition by Stage interaction (p=.010) showed PA-CBTI (vs Ind-CBTI) adhered better in avoiding naps during Build (vs Maintain). Stimulus Control Therapy: PA-CBTI (vs Ind-CBTI) adhered better to avoiding daytime wake time-in-bed (p=.017), especially during Build (interaction p=.071); Condition by Stage interaction (p=.017) showed PA-CBTI (vs Ind-CBTI) adhered better to avoiding overnight wake time-in-bed during Maintain (vs Build). Both conditions had better adherence to avoiding daytime and wake time-in-bed after final awakening during Maintain (vs Build) Stage (ps&lt;.001).

Conclusion

Adherence to CBT-I includes multiple indicators showing distinct features as the intervention progresses across different stages. Aspects of adherence appear modifiable, and adding bedpartners to CBT-I improved adherence to specific aspects of the intervention (i.e., avoiding naps, daytime wake time-in-bed, overnight wake time-in-bed). The Build and Maintain stages of treatment appear to be associated with better adherence to different aspects of the intervention (Sleep Restriction Therapy and Stimulus Control Therapy, respectively).

SCOPE: safer care for older persons (in residential) environments-a pilot study to enhance care aide-led quality improvement in nursing homes

Background

Nursing home residents require daily support. While care aides provide most of this support they are rarely empowered to lead quality improvement (QI) initiatives. Researchers have shown that care aide-led teams can successfully participate in a QI intervention called Safer Care for Older Persons in Residential Care Environments (SCOPE). In preparation for a large-scale study, we conducted a 1-year pilot to evaluate how well coaching strategies helped teams to enact this intervention. Secondarily, we measured if improvements in team cohesion and communication, and resident quality of care, occurred.

Methods

This study was conducted using a prospective single-arm study design, on 7 nursing homes in Winnipeg Manitoba belonging to the Translating Research in Elder Care research program. One QI team was selected per site, led by care aides who partnered with other front-line staff. Each team received facilitated coaching to enact SCOPE during three learning sessions, and additional support from quality advisors between these sessions. Researchers developed a rubric to evaluate how well teams enacted their interventions (i.e., created actionable aim statements, implemented interventions using plan-do-study-act cycles, and used measurement to guide decision-making). Team cohesion and communication were measured using surveys, and changes in unit-level quality indicators were measured using Resident Assessment Instrument-Minimum Data Set data.

Results

Most teams successfully enacted their interventions. Five of 7 teams created adequate-to-excellent aim statements. While 6 of 7 teams successfully implemented plan-do-study-act cycles, only 2 reported spreading their change ideas to other residents and staff on their unit. Three of 7 teams explicitly stated how measurement was used to guide intervention decisions. Teams scored high in cohesion and communication at baseline, and hence improved minimally. Indicators of resident quality care improved in 4 nursing home units; teams at 3 of these sites were scored as ‘excellent’ in two or more enactment areas, versus 1 of the 3 remaining teams.

Conclusions

Our coaching strategies helped most care aide-led teams to enact SCOPE. Coaching modifications are needed to help teams more effectively use measurement. Refinements to our evaluation rubric are also recommended.

Care Aides’ Perceptions of Caring for Nursing Home Residents With Past Psychological Trauma

The dynamic interplay between dementia and psychological trauma can exert powerful effects on nursing home residents’ behavioral symptoms and quality of life. Our objectives in this exploratory study were to assess care aides’ perceptions of how often they worked with residents with past psychological trauma, the types of trauma encountered, and reasons for these beliefs. We conducted semi-structured cognitive interviews (n = 10) with care aides in June 2019 to inform the development of a trauma needs assessment (4 questions) that we included in a large survey of nursing staff (2019 - 2020). Care aides (n = 3761) were sampled from 91 randomly selected urban nursing homes stratified by health region, owner operator model, and size. We completed basic statistics and content analyses. Care aides identified residents they believed to have psychological trauma histories and provided reasons for their beliefs. Approximately 12% of the reported traumatic events were disclosed to staff. The most common, broad categories of trauma to emerge during analysis were abuse (40%) and war exposure (30%). Each had sub-categories. The most common categories of signs of trauma were re-experiencing symptoms such as flashbacks and nightmares (28%), and avoidance of specific triggers, such as water or intimate care (24%). The majority of the reported signs of trauma were persistent and distressing for staff and residents. Some behaviours assumed to be responsive behaviours of dementia may relate to traumatic stress symptomatology. Implementing trauma-informed supports for residents and care aides is essential to person-centred care and optimal quality of life.

Intervention to decrease salt intake inadequacy using a control device to monitor and control salt use when cooking at home – iMC SALT preliminary results

Introduction

Excessive salt intake is one of the greatest risks to public health, making urgent to propose measures to reduce its intake and bring great benefits to reduce cardiovascular diseases risk. In the Portuguese population, the main source of salt consumption is the salt that is added during food preparation and cooking meals.

Purpose

The main aim of this study was to assess whether an intervention using a dosing salt device (Salt Control H) in food preparation and cooking has beneficial effects in salt intake.

Methods

This was a two-arm randomized controlled trial. A total of 88 workers from a public university (50% female; mean age 47.2±11.4 years), were randomly assigned to a intervention (I; n=42) or a control group (C; n=46). The intervention was delivered by health professionals in an occupational medicine setting, asking participants to use a salt control device that delivers the maximum amount of salt to add in food preparation and cooking, according to the number and age of the persons who will consume the meal, during 8 weeks. Primary outcome was the 24-hour urinary sodium excretion (Na24), validated by creatinine coefficient, and secondary outcome was 24-h urinary sodium-to-potassium ratio (Na/K24). Parametric tests were used to assess differences between urinary data stratified by C or I group and Mann-Whitney to evaluate differences between stratified groups according to meet WHO daily recommendations of intake.

Results

At baseline, there was no significant differences in mean Na24 (C: 3145.5±1420.1 and I:3268.7±1159.8 mg/d, p=0.096) and Na/K24 (C: 2.0±0.9 and I: 2.1±0.8 mg/d, p=0.792) between the two groups. After 8 weeks intervention, a Na24 and Na/K24 non statistically significant decrease was observed in the I group (to 3094.1±1391 and 2.0±0.8 mg/d), as opposed to the C group (to 3262.5±1527.0 and 2.2±0.9 mg/d). The proportion of participants from I group that present Na&lt;2000 mg/d increased (from 17 to 29%) as the proportion of participants that present Na/K24 &lt;1 (from 0 to 12%) without significant differences from C group (p=0.214 for Na &lt;2000 mg/d and p=0.383 for Na/K24 &lt;1).

Conclusion

The Salt Control H measurement device showed promising results to increase adherence to daily salt intake recommendations. The device is a useful and practical tool for educating individuals about dietary salt doses to add to meals cooked at home.

Making Quality Improvement Data Meaningful for Long-Term Care Administrators

Tailoring feedback data to engage end-user stakeholders when sharing organizational context data is a central component of quality improvement and integrated knowledge translation. For over a decade, our research team has collected survey data (using the validated Alberta Context Tool) on modifiable aspects of organizational context from long-term care (LTC) staff (e.g., nurses, unregulated providers) across a representative cohort of 94 LTC facilities in Western Canada. We have fed back data at the facility and care unit level with the goal of making research findings more useful for decision-making and aiding improvement efforts. We have used a binary method (more favourable / less favourable organizational context) to report multidimensional data. While useful to our stakeholders (e.g., administrators) we are continually seeking ways to increase the detail in our reporting, while maintaining usability for stakeholders. We have now developed a more detailed method – the context rank summary, which displays rankings of care units within and across LTC facilities. In this study, we used a qualitative descriptive design to explore perspectives of administrators and managers (leaders) from LTC facilities on the two different methods for reporting survey data. We conducted a total of three focus groups with 16 leaders in the Maritimes and Ontario, Canada. Transcripts were analysed using content analysis. Leaders preferred a feedback report that combines a binary method with the greater detail of the context rank summary. Providing organizational context data that is more meaningful, relevant and actionable could offer an additional path to identifying areas for improvement.

Who Doesn't Come Home? Factors Influencing Mortality Among Long-Term Care Residents Transitioning to and From Emergency Departments in Two Canadian Cities

Residents of long-term care (LTC) whose deaths are imminent are likely to trigger a transfer to the emergency department (ED), which may not be appropriate. Using data from an observational study, we employed structural equation modeling to examine relationships among organizational and resident variables and death during transitions between LTC and ED. We identified 524 residents involved in 637 transfers from 38 LTC facilities and 2 EDs. Our model fit the data, (χ² = 72.91, df = 56, p = .064), explaining 15% variance in resident death. Sustained shortness of breath (SOB), persistent decreased level of consciousness (LOC) and high triage acuity at ED presentation were direct and significant predictors of death. The estimated model can be used as a framework for future research. Standardized reporting of SOB and changes in LOC, scoring of resident acuity in LTC and timely palliative care consultation for families in the ED, when they are present, warrant further investigation.

Association of Work Environment With Missed and Rushed Care Tasks Among Care Aides in Nursing Homes

IMPORTANCE

In Canada, approximately 81% of residents of nursing homes live with mild to severe cognitive impairment. Care needs of this population are increasingly complex, but resources, such as staffing, for nursing homes continue to be limited. Staff risk missing or rushing care tasks and interfering with quality of care and life.

OBJECTIVE

To assess the association of work environment with missing and rushing essential care tasks in nursing homes.

DESIGN, SETTING, AND PARTICIPANTS

This cross-sectional study used survey data collected from a random sample of 93 urban nursing homes in Western Canada, stratified by health region, owner-operator model, and facility size, between May and December 2017. All 5411 eligible care aides were invited to participate, and 4016 care aides agreed and completed structured, computer-assisted interviews in person. Analyses were conducted from July 4, 2018, to February 27, 2019.

MAIN OUTCOMES AND MEASURES

Self-reported number of essential care tasks missed (range, 0-8) or rushed (range, 0-7) in the most recent shift. Two-level random intercept hurdle regressions controlled for care aide, care unit, and nursing home characteristics.

RESULTS

Of 4016 care aides, 2757 (68.7%) were 40 years or older, 3574 (89.1%) were women, and 1353 (66.3%) spoke English as an additional language. For their most recent shift, 2306 care aides (57.4%) reported missing at least 1 essential care task and 2628 care aides (65.4%) reported rushing at least 1 essential care task. Care aides on units with more favorable work environments (eg, more effective leadership, better work culture, higher levels of buffering resources) were less likely to miss any care tasks (odds ratio, 1.59; 95% CI, 1.34-1.90; P < .001) and less likely to rush any care task (odds ratio, 1.66; 95% CI, 1.38-1.99; P < .001).

CONCLUSIONS AND RELEVANCE

This study found that rates of missed and rushed essential care in Canadian nursing homes were high and were higher in units with less favorable work environments. This finding suggests that work environment should be added to the list of modifiable factors associated with improving nursing home care, as it may be an important pathway for improving quality of care. Further research is needed to understand associations of missed and rushed care and of improving work environments with outcomes among residents of nursing homes.

Group differences in social inclusion between young adults aged 18 to 25 with serious mental illness and same-aged peers from the general community

AIMS

Young adults with serious mental illness (SMI) are thought to be socially excluded. However, psychometric measures of social inclusion have not been employed to examine group differences relative to peers from the general community. The aim of this study was to employ such a measure to determine differences in social inclusion between young adults with SMI and peers from the general community.

METHODS

A cross-sectional hierarchical logistic regression was conducted to identify which dimensions and individual indicators from the Filia Social Inclusion Measure (F-SIM) discriminated between n = 152 young adults aged 18-25 from the general community (M = 21.36, SD = 2.16) and n = 159 young adults aged 18-25 with SMI (M = 21.13, SD = 2.21).

RESULTS

Group membership was accounted for by Interpersonal Connections (Nagelkerke R² = .32), Vocational & Financial Security (Nagelkerke R² = .32) and Healthy Independent Lifestyle (Nagelkerke R² = .08) dimensions of the F-SIM. Relative to young adults from the general community, those with SMI were five times less likely to feel they had friends who would call on them in a crisis, odds ratio (OR) = .19 (95%CI = .04, .53), p = .04, almost five times more likely to live with their parents, OR = 4.79 (95%CI = 1.98,11.15), p = .004, almost four times less likely to have worked/studied any time over the past 12 months, OR = .27 (95%CI = .11,.64), p < .001, and three-and-a-half times more likely to report unstable accommodation, OR = 3.58 (95%CI = 1.14, 11.15), p = .03.

CONCLUSION

Young adults with SMI are socially excluded relative to peers from the general community in terms of interpersonal connections, vocational engagement, autonomy/independence and housing stability. In addition to the well-established focus on vocational engagement, interventions to improve social inclusion in this population must promote reciprocity within social relationships and healthy autonomy/independence (including stable housing).

Emergence of carriage of CTX-M-15 in faecal Escherichia coli in horses at an equine hospital in the UK; increasing prevalence over a decade (2008-2017)

Background

This study investigated changes over time in the epidemiology of extended-spectrum β-lactamase (ESBL) producing Escherichia coli within a single equine referral hospital in the UK. Faecal samples were collected from hospitalised horses in 2008 and 2017, processed using selective media and standard susceptibility laboratory methods. A novel real-time PCR with high resolution melt analysis was used to distinguish bla_CTX-M-1 and bla_CTX-M-15 within CTX-M-1 group.

Results

In 2008, 457 faecal samples from 103 horses were collected, with ESBL-producing E. coli identified in 131 samples (28.7, 95% CI 24.6–33.1). In 2017, 314 faecal samples were collected from 74 horses with ESBL-producing E. coli identified in 157 samples (50.0, 95% CI 44.5–55.5). There were 135 and 187 non-duplicate ESBL-producing isolates from 2008 and 2017, respectively. In 2008, 12.6% of isolates belonged to CTX-M-1 group, all carrying bla_CTX-M-1, whilst in 2017, 94.1% of isolates were CTX-M-1 group positive and of these 39.2 and 60.8% of isolates carried bla_CTX-M-1 and bla_CTX-M-15, respectively. In addition, the prevalence of doxycycline, gentamicin and 3rd generation cephalosporin resistance increased significantly from 2008 to 2017 while a decreased prevalence of phenotypic resistance to potentiated sulphonamides was observed.

Conclusions

The real-time PCR proved a reliable and high throughput method to distinguish between bla_CTX-M-1 and bla_CTX-M-15. Furthermore, its use in this study demonstrated the emergence of faecal carriage of CTX-M-15 in hospitalised horses, with an increase in prevalence of ESBL-producing E. coli as well as increased antimicrobial resistance to frequently used antimicrobials.

The effect of profession on burnout in hospital staff

Background

A high level of burnout has been described in health professionals. However, literature regarding other hospital employees is scarce.

Aims

To assess the prevalence of burnout in different professional groups of hospital staff and how the professional category is associated with levels of burnout.

Methods

Employees of a University Hospital in Portugal completed a self-administered online questionnaire in 2014-2015. We used the Portuguese version of the Maslach Burnout Inventory-Human Services Survey and scored three dimensions of burnout (emotional exhaustion, depersonalization, personal accomplishment) as low, average or high. We estimated odds ratios (OR) and 95% confidence intervals (95% CI) by logistic regression, adjusting for age, sex, use of anxiolytic/antidepressant drugs and job satisfaction.

Results

There was a 10% response rate; 368 questionnaires were available for analysis. High levels of burnout due to emotional exhaustion were observed in all professional categories. Nurses, administrative staff and technicians more frequently scored higher levels of emotional exhaustion (59%, 50% and 50%, respectively) and lack of personal accomplishment (41%, 52% and 38%, respectively) than physicians and healthcare assistants. Not all professionals scored highly for depersonalization. Emotional exhaustion scores were significantly lower in healthcare assistants than nurses (adjusted OR 0.26, 95% CI 0.10-0.64).

Conclusions

Burnout affects all professional categories of hospital staff. Future studies should use larger, more representative samples of hospital staff, perform longitudinal analyses and analyse data on specifics of each professional category and other potential confounders.

Implementing Frontline Worker-Led Quality Improvement in Nursing Homes: Getting to "How"

BACKGROUND

Despite emerging frameworks for quality improvement (QI) implementation, little is known about how the implementation process works, particularly in nursing home settings. A study was conducted to describe "how"' a complex frontline worker-led QI program was implemented in nursing homes.

METHODS

Six focus groups were conducted in February 2017 with participants of a year-long, multicomponent, unit-level QI intervention in seven nursing homes in the Canadian province of Manitoba. Constant comparative analysis was used to examine perspectives of different groups of QI program participants-35 health care aides, health professionals, and managers.

RESULTS

Five themes important to the implementation process were identified: (1) "supportive elements of the QI program structure," (2) "navigating the workplace," (3) "negotiating relationships," (4) "developing individual skills," and (5) "observable program impact." Data on theme integration suggest that "supportive elements of the QI program structure" (Theme 1), "developing individual skills" (Theme 4), and "observable program impact" (on residents, health care aides, and leaders; Theme 5) operated as part of a reinforcing feedback loop that boosted team members' ability to navigate the workplace, negotiate relationships, and implement the QI program.

CONCLUSION

Health care aide-led QI teams are feasible. However, a leadership paradox exists whereby worker-led QI programs also must incorporate concrete mechanisms to promote strong leadership and sponsor support to teams. The findings also point to the underexplored impact of interpersonal relationships between health care aides and professional staff on QI implementation.

Four paradigms: traffic safety in the twentieth-century United States

Traffic safety, once neglected within the larger history of the automobile in the United States, has finally been getting the attention it always deserved. Nevertheless, historians still sometimes misappraise traffic safety in one era by the standards of another. Ahistorical assumptions have contributed to misinterpretations-for example, that Americans of the 1920s were extraordinarily tolerant of traffic casualties because they did not respond to them as more recent traffic-safety paradigms would prescribe. As a corrective, four paradigms, approximately sequential, are proposed: Safety First, Control, Crashworthiness, and Responsibility. Historians are invited to borrow, modify, or replace them, and to consider their applicability to other countries. Whether these particular paradigms survive review or not, historians who are alert to safety paradigms will produce more reliable scholarship on the history of traffic safety.

Integrating patient safety into health professionals' curricula: a qualitative study of medical, nursing and pharmacy faculty perspectives

BACKGROUND

As efforts to integrate patient safety into health professional curricula increase, there is growing recognition that the rate of curricular change is very slow, and there is a shortage of research that addresses critical perspectives of faculty who are on the 'front-lines' of curricular innovation. This study reports on medical, nursing and pharmacy teaching faculty perspectives about factors that influence curricular integration and the preparation of safe practitioners.

METHODS

Qualitative methods were used to collect data from 20 faculty members (n=6 medical from three universities; n=6 pharmacy from two universities; n=8 nursing from four universities) engaged in medical, nursing and pharmacy education. Thematic analysis generated a comprehensive account of faculty perspectives.

RESULTS

Faculty perspectives on key challenges to safe practice vary across the three disciplines, and these different perspectives lead to different priorities for curricular innovation. Additionally, accreditation and regulatory requirements are driving curricular change in medicine and pharmacy. Key challenges exist for health professional students in clinical teaching environments where the culture of patient safety may thwart the preparation of safe practitioners.

CONCLUSIONS

Patient safety curricular innovation depends on the interests of individual faculty members and the leveraging of accreditation and regulatory requirements. Building on existing curricular frameworks, opportunities now need to be created for faculty members to act as champions of curricular change, and patient safety educational opportunities need to be harmonises across all health professional training programmes. Faculty champions and practice setting leaders can collaborate to improve the culture of patient safety in clinical teaching and learning settings.

Dermoscopic evaluation of nodular melanoma

IMPORTANCE

Nodular melanoma (NM) is a rapidly progressing potentially lethal skin tumor for which early diagnosis is critical.

OBJECTIVE

To determine the dermoscopy features of NM.

DESIGN

Eighty-three cases of NM, 134 of invasive non-NM, 115 of nodular benign melanocytic tumors, and 135 of nodular nonmelanocytic tumors were scored for dermoscopy features using modified and previously described methods. Lesions were separated into amelanotic/hypomelanotic or pigmented to assess outcomes.

SETTING

Predominantly hospital-based clinics from 5 continents.

MAIN OUTCOME MEASURES

Sensitivity, specificity, and odds ratios for features/models for the diagnosis of melanoma.

RESULTS

Nodular melanoma occurred more frequently as amelanotic/hypomelanotic (37.3%) than did invasive non-NM (7.5%). Pigmented NM had a more frequent (compared with invasive non-NM; in descending order of odds ratio) symmetrical pigmentation pattern (5.8% vs 0.8%), large-diameter vessels, areas of homogeneous blue pigmentation, symmetrical shape, predominant peripheral vessels, blue-white veil, pink color, black color, and milky red/pink areas. Pigmented NM less frequently displayed an atypical broadened network, pigment network or pseudonetwork, multiple blue-gray dots, scarlike depigmentation, irregularly distributed and sized brown dots and globules, tan color, irregularly shaped depigmentation, and irregularly distributed and sized dots and globules of any color. The most important positive correlating features of pigmented NM vs nodular nonmelanoma were peripheral black dots/globules, multiple brown dots, irregular black dots/globules, blue-white veil, homogeneous blue pigmentation, 5 to 6 colors, and black color. A model to classify a lesion as melanocytic gave a high sensitivity (>98.0%) for both nodular pigmented and nonnodular pigmented melanoma but a lower sensitivity for amelanotic/hypomelanotic NM (84%). A method for diagnosing amelanotic/hypomelanotic malignant lesions (including basal cell carcinoma) gave a 93% sensitivity and 70% specificity for NM.

CONCLUSIONS AND RELEVANCE

When a progressively growing, symmetrically patterned melanocytic nodule is identified, NM needs to be excluded.

Surgical preparation: are patients "ready" for stress urinary incontinence surgery?

INTRODUCTION AND HYPOTHESIS

Patient preparedness for stress urinary incontinence (SUI) surgery is associated with improvements in post-operative satisfaction, symptoms and quality of life (QoL). This planned secondary analysis examined the association of patient preparedness with surgical outcomes, treatment satisfaction and quality of life.

METHODS

The ValUE trial compared the effect of pre-operative urodynamic studies with a standardized office evaluation of outcomes of SUI surgery at 1 year. In addition to primary and secondary outcome measures, patient satisfaction with treatment was measured using a five-point Likert scale (very dissatisfied to very satisfied) that queried subjects to rate the treatment's effect on overall incontinence, urge incontinence, SUI, and frequency. Preparedness for surgery was assessed using an 11-question Patient Preparedness Questionnaire (PPQ).

RESULTS

Based on PPQ question 11, 4 out of 5 (81 %) of women reported they "agreed" or "strongly agreed" that they were prepared for surgery. Selected demographic and clinical characteristics were similar in unprepared and prepared women. Among SUI severity baseline measures, total UDI score was significantly but weakly associated with preparedness (question 11 of the PPQ; Spearman's r = 0.13, p = 0.001). Although preparedness for surgery was not associated with successful outcomes, it was associated with satisfaction (r s = 0.11, p = 0.02) and larger PGI-S improvement (increase; p = 0.008).

CONCLUSIONS

Approximately half (48 %) of women "strongly agreed" that they felt prepared for SUI. Women with higher pre-operative preparedness scores were more satisfied, although surgical outcomes did not differ.

Relating centromeric topography in fixed human chromosomes to α-satellite DNA and CENP-B distribution

Despite extensive analyses on the centromere and its associated proteins, detailed studies of centromeric DNA structure have provided limited information about its topography in condensed chromatin. We have developed a method with correlative fluorescence light microscopy and atomic force microscopy that investigates the physical and structural organization of α-satellite DNA sequences in the context of its associated protein, CENP-B, on human metaphase chromosome topography. Comparison of centromeric DNA and protein distribution patterns in fixed homologous chromosomes indicates that CENP-B and α-satellite DNA are distributed distinctly from one another and relative to observed centromeric ridge topography. Our approach facilitates correlated studies of multiple chromatin components comprising higher-order structures of human metaphase chromosomes.

Feedback reporting of survey data to healthcare aides

Background

This project occurred during the course of the Translating Research in Elder Care (TREC) program of research. TREC is a multilevel and longitudinal research program being conducted in the three Canadian Prairie Provinces of Alberta, Saskatchewan, and Manitoba. The main purpose of TREC is to increase understanding about the role of organizational context in influencing knowledge use in residential long-term care settings. The purpose of this study was to evaluate healthcare aides’ (HCAs) perceptions of a one-page poster designed to feed back aggregated data (including demographic information and perceptions about influences on best practice) from the TREC survey they had recently completed.

Methods

A convenience sample of 7 of the 15 nursing homes participating in the TREC research program in Alberta were invited to participate. Specific facility-level summary data were provided to each facility in the form of a one-page poster report. Two weeks following delivery of the report, a convenience sample of HCAs was surveyed using one-to-one structured interviews.

Results

One hundred twenty-three HCAs responded to the evaluation survey. Overall, HCAs’ opinions about presentation of the feedback report and the understandability, usability, and usefulness of the content were positive. For each report, analysis of data and production and inspection of the report took up to one hour. Information sessions to introduce and explain the reports averaged 18 minutes. Two feedback reports (minimum) were supplied to each facility at a cost of CAN$2.39 per report, for printing and laminating.

Conclusions

This study highlights not only the feasibility of producing understandable, usable, and useful feedback reports of survey data but also the value and importance of providing feedback to survey respondents. More broadly, the findings suggest that modest strategies may have a positive and desirable effect in participating sites.

Core competencies for patient safety research: a cornerstone for global capacity strengthening

Background

Tens of millions of patients worldwide suffer disabling injuries or death every year due to unsafe medical care. Nonetheless, there is a scarcity of research evidence on how to tackle this global health priority. The shortage of trained researchers is a major limitation, particularly in developing and transitional countries.

Objectives

As a first step to strengthen capacity in this area, the authors developed a set of internationally agreed core competencies for patient safety research worldwide.

Methods

A multistage process involved developing an initial framework, reviewing the existing literature relating to competencies in patient safety research, conducting a series of consultations with potential end users and international experts in the field from over 35 countries and finally convening a global consensus conference.

Results

An initial draft list of competencies was grouped into three themes: patient safety, research methods and knowledge translation. The competencies were considered by the WHO Patient Safety task force, by potential end users in developing and transitional countries and by international experts in the field to be relevant, comprehensive, clear, easily adaptable to local contexts and useful for training patient safety researchers internationally.

Conclusions

Reducing patient harm worldwide will require long-term sustained efforts to build capacity to enable practical research that addresses local problems and improves patient safety. The first edition of Competencies for Patient Safety Researchers is proposed by WHO Patient Safety as a foundation for strengthening research capacity by guiding the development of training programmes for researchers in the area of patient safety, particularly in developing and transitional countries, where such research is urgently needed.

Validity of administrative data claim-based methods for identifying individuals with diabetes at a population level

OBJECTIVES

This study assessed the validity of a widely-accepted administrative data surveillance methodology for identifying individuals with diabetes relative to three laboratory data reference standard definitions for diabetes.

METHODS

We used a combination of linked regional data (hospital discharge abstracts and physician data) and laboratory data to test the validity of administrative data surveillance definitions for diabetes relative to a laboratory data reference standard. The administrative discharge data methodology includes two definitions for diabetes: a strict administrative data definition of one hospitalization code or two physician claims indicating diabetes; and a more liberal definition of one hospitalization code or a single physician claim. The laboratory data, meanwhile, produced three reference standard definitions based on glucose levels +/- HbA1c levels.

RESULTS

Sensitivities ranged from 68.4% to 86.9% for the administrative data definitions tested relative to the three laboratory data reference standards. Sensitivities were higher for the more liberal administrative data definition. Positive predictive values (PPV), meanwhile, ranged from 53.0% to 88.3%, with the liberal administrative data definition producing lower PPVs.

CONCLUSIONS

These findings demonstrate the trade-offs of sensitivity and PPV for selecting diabetes surveillance definitions. Centralized laboratory data may be of value to future surveillance initiatives that use combined data sources to optimize case detection.

A longitudinal examination of factors predicting anxiety during the transition to middle school

The transition from elementary to middle or junior high school is commonly regarded as a period of stress and turmoil for young adolescents, and has been associated with changes in anxiety and other psychological problems. However, less is known about risk and resilience factors that may predict these changes. This study examined changes in anxiety, as well as predictors of these changes among 77, predominantly Caucasian (88%), male and female (52%) adolescents from Grades 6 to 8. Repeated measures analysis of variance was conducted to examine the predicted grade and gender differences. Multiple regression analyses were conducted to examine the prediction of eighth grade anxiety symptoms by sixth grade self-worth, perceived social acceptance, and social support, as well as the potential moderating role of gender in these relations. Results suggested a significant decrease in anxiety, particularly social anxiety, over this period for boys but not girls. Examination of predictors of changes in anxiety suggested that, in general, global self-worth, social acceptance, and gender were each associated with overall and social anxiety. Findings are integrated with extant literature on developmental changes associated with anxiety and school transitions and clinical implications of these findings are discussed.

Review Paper: Gene Expression Profiling in Veterinary and Human Medicine: Overview of Applications and Proposed Quality Control Practices

High throughput molecular analysis of veterinary tissue samples is being applied to a wide range of research questions aimed at improving survival, development of diagnostic assays, and improving the economics of commercial production of animal products. Many of these efforts also, implicitly or explicitly, have ramifications for the clinical care of humans and, potentially, animals. Here we provide an overview of applications of gene expression profiling in veterinary research and practice. We then focus on the current state of quality control and quality assurance efforts in gene expression profiling studies, underscoring lessons learned from such analysis of human samples. Finally, we propose practices aimed at ensuring the reliability and reproducibility of such assays. The implementation of quality assurance practices by a trained pathologist is an essential link in the chain of events leading ultimately to reliable and reproducible research findings and appropriate clinical care.

Reference urodynamic values for stress incontinent women

OBJECTIVE

To determine reference urodynamic values for preoperative urodynamic studies in women undergoing surgery for pure or predominant stress urinary incontinence (SUI).

MATERIALS AND METHODS

Six hundred fifty-five women with pure or predominant SUI were enrolled in a multicenter surgical trial and were randomized to undergo a Burch or autologous fascia sling procedure as part of the Urinary Incontinence Treatment Network (UITN) Stress Incontinence Surgical Treatment Efficacy Trial (SISTEr). Preoperative free uroflowmetry, filling cystometry, and pressure flow studies were performed in all women using a standardized research protocol and standardized urodynamic interpretation guidelines. We define the normal range of urodynamic values in this population as the values that encompass 95% of the results.

RESULTS

In 655 women undergoing filling cystometry in the standing position, baseline vesical and abdominal pressures were between 12 and 60 cm H(2)O. The upper limit of detrusor pressure increase during bladder filling to maximum cystometric capacity was 16 cm H(2)O. Ten percent of women who qualified for stress incontinence surgery with a positive cough stress test on physical exam did not demonstrate urodynamic stress incontinence (USI) and less than 10% of subjects in this study demonstrated detrusor overactivity.

CONCLUSIONS

Results from a large cohort of women with SUI are now available for quantitative plausibility assessments or as reference values when interpreting urodynamic studies.
