RESUMO

The National Institute on Aging Alzheimer's Disease/Alzheimer's Disease and Related Dementias Research Implementation Milestones emphasize the need for implementation research that maximizes up-take and scale-up of evidence-based dementia care practices across settings, diverse populations, and disease trajectories. Organizational readiness for implementation is a salient consideration when planning and conducting embedded pragmatic trials, in which interventions are implemented by provider staff. The current article examines the conceptual and theoretical underpinnings of organizational readiness for implementation and the operationalization of this construct. We offer a preliminary conceptual model for explicating and measuring organizational readiness and describe the unique characteristics and demands of implementing evidence-based interventions targeting persons with dementia and/or their care partners.

RESUMO

There are 200+ tested interventions for care partners (family, friends, and fictive kin) of people living with dementia (PLWD). But these interventions do not systematically cover relevant settings. Nor do these interventions affect all relevant outcomes that matter to people and healthcare systems. We present an evidence map of settings and outcomes from translated interventions to identify gaps. Of 190 studies identified, 31 unique interventions were retained in the evidence map. Identified setting gaps included studies set solely in hospitals/medical centers or set in multiple settings. Identified outcome gaps included interventions that improved care partner beliefs about providing care, care partner negative coping strategies, PLWD resources (e.g., social support), and PLWD coping strategies. Armed with an understanding of present gaps, we call on researchers to fill the identified gaps to ensure systematic coverage of settings and evaluation of outcomes that matter to people and healthcare systems.

RESUMO

BACKGROUND: Persons living with Alzheimer's disease and related dementia (ADRD) in nursing homes (NH) are often excluded from conversations about their health/safety. These omissions impinge on personhood and the rights to have care preferences heard and honored. While persons with ADRD maintain the ability to communicate their preferences long after their decision-making abilities are affected, little is known about how persons with ADRD understand the risks associated with their preferences. METHODS: As part of a larger focused ethnography, in-depth interviews and an adapted risk propensity questionnaire explored the risk perceptions of NH residents with ADRD (N=7) associated with their preferences for care and activities of daily living. RESULTS: Residents generally self-identified as risk avoiders (M=3.2±1.84) on the risk propensity scale and were able to rate risk associated with preferences described within 5 thematic categories: 1) participation in decision-making, 2) risk awareness, 3) paying attention to safety, 4) reliance on nursing home staff and family, and 5) impacts on quality of life and quality of care. DISCUSSION: Results suggest NH residents with ADRD can express risk surrounding their preferences and should be encouraged to participate in discussions about their health and safety.

RESUMO

OBJECTIVES: The current study aimed to develop and preliminarily validate an initial version of an instrument to assess the leisure activity preferences of people receiving adult day services (ADS). METHODS: Based on previously conducted concept mapping steps, we identified 12 clusters of preferences for leisure activities. We adopted the structure of the Preferences for Everyday Living Inventory and phrased our cluster labels as questions to develop a first draft of the Preferences for Leisure Activities Inventory (P-LAI). We conducted cognitive interviews (n = 8) to revise, preliminarily validate, and preliminarily finalize the P-LAI. RESULTS: The draft of the P-LAI included 25 questions. Based on the results of the cognitive interviews, the number of questions was reduced to 21, three questions were rephrased, and evidence to support the preliminary validity of the P-LAI based on the response processes was provided. CONCLUSIONS: The P-LAI is the first instrument to assess preferences for leisure activities in the ADS environment. CLINICAL IMPLICATIONS: The preliminary results of the P-LAI allow ADS providers and healthcare professionals to assess the preferences for leisure activities of people who receive ADS in a structured way. Based on these results, preference-based services can be designed and planned, and the person-centered philosophy of care can be further operationalized in the ADS environment.

RESUMO

OBJECTIVES: The Individualized Positive Psychosocial Interaction (IPPI) is a non-pharmacological, person-centered, intervention for nursing home (NH) residents living with moderate to severe dementia. The purpose of this study was to assess the pragmatic implementation of the IPPI by leveraging Ohio's Nursing Home Quality Improvement Program (QIP). METHODS: Implementation teams collected resident mood ratings pre- and post-IPPI and completed virtual interviews to assess their Organizational Readiness for Implementing Change as well as the acceptability, feasibility, and appropriateness of the IPPI. Implementation strategies included: providing ongoing consultation; identifying and preparing champions; assessing for readiness and identifying barriers; and developing and distributing effective educational materials. RESULTS: Fifteen NHs completed the QIP (65% completion rate) and reported high organizational commitment to change and high change efficacy. NHs engaged n = 65 residents in n = 638 IPPIs. Residents experienced a positive mood change after 47% of IPPIs. NHs found the IPPI program to be highly acceptable, feasible, and appropriate. CONCLUSIONS: Overall, 65% of NHs successfully implemented the IPPI QIP with people living with moderate to severe dementia. CLINICAL IMPLICATIONS: Given the positive mood changes and high staff satisfaction, results suggest that these brief, individualized activities can be effective strategies to address the communication of distress among PLWD.

RESUMO

Currently it is unknown what people receiving adult day services (ADS) understand as leisure and the activities they prefer remain unknown. To address these gaps, we investigated the understanding of leisure of people receiving ADS. We conducted semistructured interviews with 15 people receiving ADS in Germany. Interviews were analyzed using reflexive thematic analysis. The sweet bitter symphony emphasizes the sensations that shape participant's understanding of leisure. Young, wild & free! describes the types of preferred activities. Is this our last tango? refers to the barriers. Anchors aweigh! the [ongoing] voyage describes the process by which leisure is transferred from private domain to the ADS environment. The beginning is the end is the beginning illustrates the paradox of understanding the ADS as offering a form of leisure and the adaptation to engage in nonpreference-based activities. Our findings indicate the importance in offering leisure activities that enable preference-based engagement in the ADS.

RESUMO

BACKGROUND AND OBJECTIVES: Providing preferred leisure activities appears to be an important approach to support and empower people receiving adult day services (ADS) allowing them to age in place. To provide the conceptualization for a preference instrument, we actively involved people receiving ADS in exploring the content and structure of their preferences for leisure activities. RESEARCH DESIGN AND METHODS: We chose a concept mapping methodology and involved 16 people receiving ADS. We systematically reviewed the literature and conducted semistructured interviews to generate a set of 80 preferences. Analysis of structuring these preferences resulted in a 3-dimensional cube with 12 clusters. A graphical representation was then interpreted, and the clusters were labeled. RESULTS: Our conceptualization divides preferences for leisure activities into the following: 1. Take a trip, 2. Revel in memories and catch up on the news (most important), 3. Do something for yourself and come to rest, 4. Play intelligence and parlor games, 5. Make/produce and try something alone or in a group, 6. Keep fit and cheer others on in sports (least important), 7. Learn, educate, and share knowledge, 8. Have contact with other people, 9. Attend at entertainment, cultural, and amusement events, 10. Enjoy music, your homeland, or other countries, 11. Engage in outdoor activities, and 12. Get involved, offer support, and provide companionship. DISCUSSION AND IMPLICATIONS: Our results may lead to the development of instruments and thus opens the field for further research and theory building on preferences for leisure activities of people receiving ADS.

RESUMO

Nursing homes receive complaints when actual care provided to residents misaligns with desired care, suggesting that person-centered care (PCC) and honoring resident preferences in care delivery may help prevent complaints from arising. We explore whether nursing home implementation of a PCC tool, the Preferences for Everyday Living Inventory (PELI), is related to measures of complaints. Publicly available data on Ohio nursing homes was used to examine 1,339 nursing home-year observations. Regression techniques were used to evaluate the relationship between the extent of PELI implementation and four complaint outcomes: any complaint, number of complaints, any substantiated complaint, and number of substantiated complaints. Nursing homes with complete PELI implementation were less likely to have any complaints by 4.7% points (P < .05) and any substantiated complaints by 11.5% points (P < .001) as compared to partial PELI implementers. When complete PELI implementers did have complaints, they were fewer than partial PELI implementers. Complete PELI implementers were not immune from receiving complaints; however, the complaints they did receive were fewer in number and less likely to be substantiated as compared to communities who only partially implemented a PCC tool.

RESUMO

Seven self-care behaviors-healthy coping, healthy eating, being active, taking medication, monitoring, reducing risk, and problem-solving-are recommended for individuals with diabetes to achieve optimal health and quality of life. People newly diagnosed with type 2 diabetes may find it challenging to learn and properly incorporate all of these self-care behaviors into their life. This qualitative study explored the experiences and perceived immediate self-management and psychosocial support needs in individuals newly diagnosed with type 2 diabetes. Data analysis revealed the significant challenges individuals encounter after a type 2 diabetes diagnosis. Five main themes were identified: 1) type 2 diabetes diagnosis competes with other complex life challenges, 2) difficulty in performing behavior modification actions, 3) lack of support, 4) emergence of emotional and psychological issues, and 5) need for planned individualized follow-up support after a type 2 diabetes diagnosis. This study revealed a gap in care after type 2 diabetes diagnosis. Individualized support is needed to assist people in moving successfully from diagnosis to being well equipped with the knowledge and skills necessary to properly manage the condition.

RESUMO

Background: The Preferences for Everyday Living Inventory (PELI) is a person-centered care (PCC) tool that uncovers/honors older adults' important preferences. PCC implementation in nursing homes (NHs) often requires additional resources, such as staff time. We explored if PELI implementation is associated with NH staffing levels. Methods: Using NH-year as the unit of observation (n = 1307), 2015 and 2017 data from Ohio NHs was used to examine the relationship between complete versus partial PELI implementation and staffing levels, measured in hours per resident day, for various positions and total nursing staff. Results: Complete PELI implementation was associated with higher nursing staff levels in both for-profits and not-for-profits; however, total nursing staff levels in not-for-profits were higher than for-profits (0.16 vs. 0.09 hours per resident day). The specific nursing staff associated with PELI implementation varied by ownership. Discussion: For NHs to fully implement PCC, a multifaceted approach to improve staffing is needed.

RESUMO

Background and Objectives: Person-centered care practices are essential to providing high-quality care for nursing home (NH) residents. A key component of implementing person-centered care is the assessment and fulfillment of residents' preferences. However, few NHs consistently assess and implement residents' preferences into care. From 2015 to 2019, the Ohio Department of Medicaid added the Preference for Everyday Living Inventory (PELI), a scientifically validated tool to assess residents' preferences, as a quality indicator to improve the person centeredness of Ohio's NHs. In this study, we sought to identify the associations between resident and organizational characteristics and PELI implementation in Ohio NHs. Research Design and Methods: We constructed an NH-level database that merged data from the Ohio Biennial Survey of Long-Term Care Facilities, Ohio Medicaid Cost Reports, the Certification and Survey Provider Enhanced Reports data, the WWAMI Rural Health Research Center, and the Minimum Data Set. Freestanding NHs were included if they were owned by a for-profit or not-for-profit organization, and had data collected in 1 of 2 years (n = 1,320; year 2015, n = 814; year 2017, n = 506). Descriptive statistics and multiple logistic regression were used to understand the relationships between resident demographics, NH organizational characteristics, and partial versus complete PELI implementation. Results: Most NHs (71.2%) reported complete implementation of the PELI over 2 years with implementation increasing over time. There was a relationship between complete PELI implementation and for-profit status, higher number of beds, higher Medicare funding, higher certified nursing assistants and activity staff hours, and urban location. Discussion and Implications: This work has important implications for the implementation of person-centered care interventions in NHs and our understanding of what NH characteristics are related to successful implementation. The next steps should include a continued, detailed assessment of PELI implementation and an exploration of the potential impact of PELI implementation on residents, staff, and organizational outcomes.

RESUMO

The diagnosis of type 2 diabetes initiates a new health-illness transition. However, little is known about the immediate support that people need to successfully cope with this diagnosis. This qualitative study explored the experiences and immediate support needed at the point of diagnosis among individuals with type 2 diabetes. The findings suggest the need for health care professionals to render immediate emotional support in the form of reassurance and partnership to manage the condition together. Pre- and post-counseling sessions can minimize the emotional and psychological strain associated with the new diagnosis. Individuals should be given information on available resources, as well as an immediate connection with a health care partner who can provide guidance and help with the transition.

RESUMO

OBJECTIVES: The purpose of this study is to expand on previous work testing the relationship between person-centered care (PCC) and quality outcomes in the nursing home (NH) setting. We explore if the Preferences for Everyday Living Inventory (PELI) implementation is a predictor of NH quality, as defined by deficiencies. DESIGN: Secondary data analysis of repeated cross-sections. SETTING AND PARTICIPANTS: Data from 6 sources on Ohio NHs were merged to examine 1300 NH-year observations. METHODS: Logistic regression techniques were used to evaluate the relationship between PELI implementation and 3 survey deficiency outcomes: whether the NH had a 4- or 5- deficiency star rating, deficiency score, and whether the NH had a deficiency score of 0. RESULTS: NHs with complete PELI implementation increased the probability of having a 4- or 5- deficiency star rating by 6 percentage points (P = .039). Results also show complete PELI implementation is related to lower deficiency scores and an increased probability of having a deficiency score of 0, but only a 0 deficiency score was marginally significant. CONCLUSIONS AND IMPLICATIONS: The findings indicate PCC stands to improve quality outcomes; however, benefits take time to show. Future research should seek to help improve NHs level of commitment to PCC and buy-in from policymakers.

RESUMO

The Checklist for Evidence of Person-Centered Care Approaches for Behavioral and Psychological Symptoms of Distress (BPSD) in Care Plans was developed to assess the person-centeredness of care plans for nursing home residents living with behavioral and psychological symptoms associated with dementia. The purpose of the current study was to evaluate the reliability and validity of a revised version of the Checklist. Data from a larger randomized clinical trial testing the implementation of the Evidence of Integration Triangle for BPSD were used. One hundred seventy-nine care plans for 103 residents were examined. Descriptive statistics, Rasch analysis, and inter-rater reliability were used. The Checklist demonstrated evidence of inter-rater reliability and validity based on model fit and acceptable INFIT and OUTFIT statistics. This study serves as pilot work for future Checklist use and validation efforts on a larger scale. Findings encourage a discourse on the inclusion of BPSD and person-centered approaches in care plans for those living with dementia. [Research in Gerontological Nursing, 15(6), 303-311.].

RESUMO

Nursing homes (NHs) are challenged to consistently deliver person-centered care (PCC), or care based on residents' values and preferences. NH staff associate certain resident preferences with risk. However, there are limited evidence-based person-centered risk management strategies to assist NH staff with risky resident preferences. The purpose of the current study was to explore NH staff perceptions of health and safety outcomes associated with honoring NH residents' risky preferences to inform intervention development. This descriptive, qualitative study used sequential focus groups and content analysis, revealing that nursing staff perceive negative and positive outcomes for staff and residents when seeking to honor residents' risky preferences. This finding is supported by three themes: Potential Harms to Staff, Potential Harms to Residents, and Positive Shared Outcomes. These results contribute a set of nurse-driven quality of life and quality of care outcomes for NH staff and residents associated with PCC delivery in NHs.

RESUMO

Importance: Assisted living (AL) is the largest provider of residential long-term care in the US, and the morbidity of AL residents has been rising. However, AL is not a health care setting, and concern has been growing about residents' medical and mental health needs. No guidance exists to inform this care. Objective: To identify consensus recommendations for medical and mental health care in AL and determine whether they are pragmatic. Evidence Review: A Delphi consensus statement study was conducted in 2021; as a separate effort, the extent to which the recommendations are reflected in practice was examined in data obtained from 2016 to 2021 (prepandemic). In the separate effort, data were from a 7-state study (Arkansas, Louisiana, New Jersey, New York, Oklahoma, Pennsylvania, Texas). The 19 Delphi panelists constituted nationally recognized experts in medical, nursing, and mental health needs of and care for older adults; dementia care; and AL and long-term care management, advocacy, regulation, and education. One invitee was unavailable and nominated an alternate. The primary outcome was identification of recommended practices based on consensus ratings of importance. Panelists rated 183 items regarding importance to care quality and feasibility. Findings: Consensus identified 43 recommendations in the areas of staff and staff training, nursing and related services, resident assessment and care planning, policies and practices, and medical and mental health clinicians and care. To determine the pragmatism of the recommendations, their prevalence was examined in the 7-state study and found that most were in practice. The items reflected the tenets of AL, the role of AL in providing dementia care, the need for pragmatism due to the diversity of AL, and workforce needs. Conclusions and Relevance: In this consensus statement, 43 recommendations important to medical and mental health care in AL were delineated that are highly pragmatic as a guide for practice and policy.

RESUMO

BACKGROUND: Nursing homes (NHs) are required to provide person-centered care, efforts often folded into broader culture change initiatives. Despite the known benefits of culture change, it is difficult to measure. This study aims to assess the criterion validity of the Preferences for Everyday Living Inventory (PELI) Implementation Indicator with other culture change measures. METHODS: Using data from Ohio-based NHs (n = 771), logistic regression techniques demonstrated the relationship between the PELI Implementation Indicator and two validated culture change measures, the Resident Preferences for Care (RPC) and Certified Nursing Assistant (CNA) Empowerment scales. RESULTS: There was a significant relationship between the two scales and complete PELI implementation holding all other variables constant. The RPC and CNA Empowerment scales were significantly associated with complete PELI implementation. DISCUSSION: Findings suggest that the PELI Implementation Indicator can be used as a pragmatic indicator of a community's adoption of person-centered care and culture change.

RESUMO

BACKGROUND: Nursing education influences medication administration practices, which involve clinical decision making and risk perceptions. METHOD: This mixed-methods concurrent nested study explored the relationship among knowledge, personality traits, and self-efficacy related to medication administration error in fourth-year, prelicen-sure nursing students (n = 60) who were recruited from three campuses of a large university. RESULTS: Results indicated low mean knowledge (70.75) and neuroticism (2.44) scores, and high mean self-efficacy and confidence (5.78) and conscientiousness (4.51) scores. Conscientiousness was correlated with both knowledge (r = .271, p = .036) and neuroticism (r = -.313, p = .015). Thematic analysis yielded four themes: nature of risk perceptions, more opportunities to learn, experiences with medication administration error, and intrinsic characteristics influence errors. Convergence was evident in both knowledge and personality data; self-efficacy/confidence and risk perceptions data diverged. CONCLUSION: Knowledge, personality traits, and self-efficacy appear to influence nursing students' risk perceptions of medication administration error, indicating an area for future research.

RESUMO

Nursing home (NH) providers would benefit from adopting evidence-based measures for gathering and utilizing resident preference information in their daily care activities. However, providers face barriers when implementing assessment tools used to promote person-centered care (PCC). Although Agile methodology is not commonly used in NH settings, this case study shows how it can be used to achieve the goal of delivering preference-based, PCC, within a large NH. We present a road map for breaking down care processes, prioritizing, and implementing iterative plan, do, study, act cycles using Agile methodology to enhance group collaboration on quality improvement cycles, to achieve our goal of providing preference-based PCC. We first determined if care plans reflected each resident's important preferences, developed a method for tracking whether residents attended activities that matched their preferences, and determined if residents were satisfied that their preferences were being met. These efforts had positive effects throughout the NH particularly when COVID-19 limited visitors and significantly modified staff workflow. Specifically, Agile processes helped staff to know how to honor preferences during quarantines which necessitated a shift to individualized (and not group) approaches for meeting preferences for social contact, comfort, and belonging. The ready availability of preference-based reporting was critical to quickly informing new staff on how to meet residents' most important preferences. Based on lessons learned, we describe a developmental approach that other providers can consider for adoption. Implications of this work are discussed in terms of the need for provider training in Agile methodologies to support iterative improvements, the need for policies that reimburse providers for their efforts, and additional research around workflow processes.

RESUMO

Background and Objectives: Behavioral and psychological symptoms of dementia (BPSD) commonly occur in persons living with dementia. Bright light (BL) interventions have shown some positive impact on BPSD. Ambient lighting is a more efficient approach to delivering BL with better compliance and less staff workload than individual-based lighting interventions. Yet, its effect has not been systematically reviewed. This review synthesized research evidence on the effect of ambient BL on BPSD. Research Design and Methods: This review searched literature from PubMed (Medline), CINAHL, Scopus, Web of Science, and Cochrane in February 2021. Original research testing the effect of ambient BL on BPSD in persons with dementia was included. Two reviewers independently screened, extracted data, and assessed the quality of each article. Results: Nine studies were reviewed with 1 randomized controlled trial and 8 quasi-experimental studies. The sample size ranged from 14 to 89 participants across care settings. While not all studies showed positive results, evidence from multiple studies revealed the positive effect of ambient BL on depressive symptoms and agitation in persons with dementia. The ambient BL that showed a positive effect targeted at approximately 350-750 lux, 4,500-9,325 K, and/or circadian stimulus = 0.375-0.4 for 10-12 hr a day for 4 weeks or longer. Evidence on other BPSD was mixed or too limited to draw conclusions. Discussion and Implications: A preponderance of evidence suggests that, when properly designed and implemented, ambient BL shows promise in reducing depressive symptoms and agitation. Future research, using more rigorous designs, is needed to further test the effect of ambient BL on BPSD with attention to lighting parameters, measurement approaches, and intervention fidelity.
