Contextually appropriate nurse staffing models: a realist review protocol

INTRODUCTION

Decisions about nurse staffing models are a concern for health systems globally due to workforce retention and well-being challenges. Nurse staffing models range from all Registered Nurse workforce to a mix of differentially educated nurses and aides (regulated and unregulated), such as Licensed Practical or Vocational Nurses and Health Care Aides. Systematic reviews have examined relationships between specific nurse staffing models and client, staff and health system outcomes (eg, mortality, adverse events, retention, healthcare costs), with inconclusive or contradictory results. No evidence has been synthesised and consolidated on how, why and under what contexts certain staffing models produce different outcomes. We aim to describe how we will (1) conduct a realist review to determine how nurse staffing models produce different client, staff and health system outcomes, in which contexts and through what mechanisms and (2) coproduce recommendations with decision-makers to guide future research and implementation of nurse staffing models.

METHODS AND ANALYSIS

Using an integrated knowledge translation approach with researchers and decision-makers as partners, we are conducting a three-phase realist review. In this protocol, we report on the final two phases of this realist review. We will use Citation tracking, tracing Lead authors, identifying Unpublished materials, Google Scholar searching, Theory tracking, ancestry searching for Early examples, and follow-up of Related projects (CLUSTER) searching, specifically designed for realist searches as the review progresses. We will search empirical evidence to test identified programme theories and engage stakeholders to contextualise findings, finalise programme theories document our search processes as per established realist review methods.

ETHICS AND DISSEMINATION

Ethical approval for this study was provided by the Health Research Ethics Board of the University of Alberta (Study ID Pro00100425). We will disseminate the findings through peer-reviewed publications, national and international conference presentations, regional briefing sessions, webinars and lay summary.

The relationship between nursing home staffing and resident safety outcomes: A systematic review of reviews

BACKGROUND

Resident safety is an important topic for nursing home practice with up to 33 % of residents subjected to an adverse event. In spite of a large evidence base examining the relationship between nursing home staffing and resident outcomes, the findings of several systematic reviews remain inconclusive and contradicting, possibly due to methodological shortcomings.

OBJECTIVE

The main aim of this review was to provide a comprehensive overview of the literature on nursing home staffing and its relationship with resident safety outcomes.

DESIGN

We undertook a systematic review of reviews. We searched Medline, CINAHL and Embase by the end of November 2022. Reviews were included if they assessed the relationship between nursing home staffing and resident safety outcomes using objective measures and data at resident level. Quality appraisal was conducted using the SIGN-checklist, but we did not exclude any reviews based on quality assessment. We used a narrative approach, tables and figures to summarize the findings.

RESULTS

We included 13 systematic reviews published between 2006 and 2022 building on primary evidence from 1977 to 2022. Twelve reviews investigated the relationship between nurse staffing and resident safety outcomes (187 unique primary studies), and one review focused on allied health professionals (28 primary studies). Five reviews originated as work to inform governmental recommendations on staffing. We found diverse approaches used to investigate the staffing-outcome relationship with regard to design, timeframe, operationalization, data-source and theoretical rationales guiding the studies. The most prominently reported resident safety outcomes were pressure ulcers and urinary tract infections. Commonly reported staffing measures included number and level of education of nursing home staff. Based on narrative summaries, staffing seems to have a favorable relationship with resident safety outcomes, but logic models explaining the mechanisms of this relationship were sparsely reported.

CONCLUSIONS

The existing literature shows methodological limitations that demand a change in research on the staffing-outcome relationship in the nursing home setting. Our work highlights the need for carefully designed primary studies that address the pertinent shortcomings by design, timeframe, operationalization, data-source and theoretical rationales. These future studies will allow to carefully examine the causal relationship between selected staffing measures and resident safety outcomes in further detail and serve as legitimate evidence bases to inform action plans for clinical practice and to evaluate staffing policies.

Determinants of Quality of Life (QoL) in Female Caregivers in Elderly Care Facilities in Korea

BACKGROUND

The purpose of this study was to analyze the effects of general characteristics, fatigue, depression, self-efficacy, job stress and interpersonal relationships on the quality of life (QoL) of caregivers in nursing hospitals and use them as basic data for intervention programs to improve the quality of life of caregivers.

METHODS

The participants in the study were 137 caregivers, aged 52-76, who were actively working in nursing hospitals. Data were collected from caregivers by visiting 9 hospitals in 6 cities, with a questionnaire of fatigue, depression, self-efficacy, job stress, interpersonal relationship, quality of life.

RESULTS

Age, marriage, marital satisfaction, education, education experience of QoL, monthly income, perceived economic status, hobby or leisure activity, and number of disease showed differences in the degree of QoL at a statistically significant level. In stage 1, economic status (β = -0.18, p = 0.033) and hobby or leisure activity (β = 0.19, p = 0.025) were influencing factors (F = 4.58, p < 0.001). In stage 2, monthly income (β = -0.19, p = 0.034) and perceived economic status (β = -0.18, p = 0.035) were influencing factors. In stage 3, age (β = -2.80, p = 0.006), perceived economic status (β = -2.41, p = 0.017), self-efficacy (β = 3.19, p = 0.002) and interpersonal relationship (β = 7.12, p < 0.001) were influencing factors which showed 61.5% explanatory power (F = 12.88, p < 0.001). Since the subject's fatigue, depression, and stress did not affect the quality of life, further research is needed.

CONCLUSIONS

In order to improve the quality of life of caregivers, it would be necessary to develop interventions for raising their self-efficacy and interpersonal relationship by considering their degree of economic status, hobby or leisure activity, monthly income, and age.

Flanders Nursing Home (FLANH) project: Protocol of a multicenter longitudinal observational study on staffing, work environment, rationing of care, and resident and care worker outcomes

BACKGROUND

While the demand for high quality of care in nursing homes is rising, it is becoming increasingly difficult to recruit and retain qualified care workers. To date, evidence regarding key organizational factors such as staffing, work environment, and rationing of care, and their relationship with resident and care worker outcomes in nursing homes is still scarce. Therefore, the Flanders Nursing Home (FLANH) project aims to comprehensively examine these relationships in order to contribute to the scientific knowledge base needed for optimal quality of care and workforce planning in nursing homes.

METHODS

FLANH is a multicenter longitudinal observational study in Flemish nursing homes based on survey and registry data that will be collected in 2023 and 2025. Nursing home characteristics and staffing variables will be collected through a management survey, while work environment variables, rationing of care, and care worker characteristics and outcomes will be collected through a care worker survey. Resident characteristics and outcomes will be retrieved from the Belgian Resident Assessment Instrument for long-Term Care Facilities (BelRAI LTCF) database. Multilevel regression analyses will be applied to examine the relationships between staffing variables, work environment variables, and rationing of care and resident and care worker outcomes.

CONCLUSION

This study will contribute to a comprehensive understanding of the nursing home context and the interrelated factors influencing residents and care workers. The findings will inform the decision-making of nursing home managers and policymakers, and evidence-based strategies to optimize quality of care and workforce planning in nursing homes.

An organizational design perspective on the monthly self-scheduling process in nursing homes: A multiple case study

AIMS

To describe the monthly self-scheduling process in nursing homes (NH), to determine how specific organizational design characteristics (including interpersonal relationships and leadership style) influence this process, and to examine the effect on individual, team, and organization-related outcomes.

DESIGN

A multiple case study using an organizational design perspective as the overarching theoretical and explanatory framework.

METHODS

Data collection was performed in four Belgian NH during Spring 2019 using semi-structured interviews (n = 39), documents, and observations. Open, axial, and selective coding was used for the data reduction process, and a within-case and cross-case analysis was performed. The COREQ checklist was used for reporting the findings.

RESULTS

One group (two NH) used self-scheduling because it corresponds with their decentralized organizational design. Together with a motivating head nurse and additional resources during the core phase of the process, this led to positive outcomes. In contrast, another group used self-scheduling under the assumption that it would solve the mismatch between their organizational design and other organizational problems, which resulted in less positive work attitudes.

CONCLUSION

Self-scheduling should match the organizational structure and culture. Additional resources and an adaptive leadership style can help mobilize and support employees. Future research may use quantitative methods to confirm positive outcomes.

IMPACT

This study contributes to the rare literature on self-scheduling in NHs by focusing on the monthly self-scheduling process and by including an organizational design perspective. NH management can become informed of different self-scheduling methodologies and the impact of specific organizational characteristics on this process. Head nurses can become aware that they need to adapt their leadership style to obtain improved outcomes.

PATIENT OR PUBLIC CONTRIBUTION

Three members of the study team met with several caregivers during field visits to conduct interviews and to observe the monthly self-scheduling process.

Daily Variation in Nursing Home Staffing and Its Association With Quality Measures

IMPORTANCE

Average staffing measures are a focus of nursing homes' quality assessments and reporting. They may, however, mask daily variation in staffing, additional information that could be important for understanding nursing home quality and relative ranking.

OBJECTIVE

To examine daily variation in staffing, its association with quality, and whether daily variation provides information regarding quality ranking of nursing homes over and above the information provided by average staffing levels.

DESIGN, SETTING, AND PARTICIPANTS

This quality improvement study included registered nurses (RNs) and certified nurse aide (CNAs) at 13 339 certified nursing homes throughout the United States during 2017 to 2018. Retrospective analyses of the Payroll-Based Journal, Medicare Cost Reports, and Nursing Home Care Compare were conducted. Data were analyzed from January 2017 to December 2018.

MAIN OUTCOMES AND MEASURES

Three measures of daily variation, ie, coefficient of variation (COV), total outlier days (TOD), and low outlier days (LOD), were calculated for RNs and CNAs. The association between these measures and quality rankings and other facility characteristics were evaluated.

RESULTS

A total of 13 339 nursing homes were included in this study, with 9476 (71%) for-profit facilities. The mean (SD) hours-per-resident-day were 0.41 (0.29) for RNs and 2.16 (0.49) for CNAs, and a mean (SD) 55% (26%) of residents were Medicaid beneficiaries. Outcome measures were as follows: mean (SD) COV, 0.5 (0.6) for RNs and 0.1 (0.1) for CNAs; mean (SD) TOD, 220 (69) for RNs and 44 (45) for CNAs; and mean (SD) LOD, 116 (45) for RNs and 22 (24) for CNAs. All 3 variation measures, for both RNs and CNAs, were significantly associated with both the 5-Star Quality Measures (COV among RNs, -0.014 [95% CI, -0.021 to -0.007]; P < .001; COV among CNAs: -0.004 [95% CI, -0.006 to -0.003]; P < .001; TOD among RNs, -3.79 [95% CI, -4.59 to -2.99]; P < .001; TOD among CNAs, -2.52 [95% CI, -3.08 to -1.96]; P < .001; LOD among RNs, -2.46 [95% CI, -3.03 to -1.88]; P < .001; LOD among CNAs, -1.29 [95% CI, -1.58 to -0.99]; P < .001) and the 5-Star Survey rankings (COV among RNs,-0.026 [95% CI, -0.033 to -0.019]; P < .001; COV among CNAs: -0.006 [95% CI, -0.007 to -0.004]; P < .001; TOD among RNs, -5.10 [95% CI, -5.97 to -4.23]; P < .001; TOD among CNAs, -4.16 [95% CI, -4.77 to -3.55]; P < .001; LOD among RNs, -3.04 [95% CI, -3.65 to -2.44]; P < .001; LOD among CNAs, -1.97 [95% CI, -2.29 to -1.65]; P < .001) published in Nursing Home Care Compare. Low κ values, ranging from 0.23 to 0.63, indicated that the variation measures add information about ranking to the information provided by average staffing measure.

CONCLUSIONS AND RELEVANCE

These findings highlight the importance of reporting daily variation in staffing to improve understanding of the relationship between staffing and quality. They suggest that 2 facilities with the same average staffing achieve different quality of resident care and survey ratings in association with on the day-to-day variation in staffing. Measures of daily staffing may enhance the value of Nursing Home Care Compare for nursing homes and others engaged in quality improvement and consumers searching for high quality nursing homes.

Effects of registered nurse staffing levels, work environment, and education levels on adverse events in nursing homes

This study examined the effects of nurse staffing levels, work environment, and education levels on adverse events in nursing homes. A cross-sectional study was conducted involving 216 nurses working in 62 nursing homes in South Korea, using self-reported questionnaires and data from the National Health Insurance Service of South Korea. A logistic regression model was used to investigate the effects of nurse staffing levels, work environment, and nursing education levels on the adverse events experienced by residents. An increase of one resident per nurse was significantly associated with a higher incidence of medication error, pressure ulcers and urinary tract infections. A poor work environment increased the incidence of adverse events. Compared to nurses with a bachelor’s degree or higher, those with diplomas reported increased incidence rates of pressure ulcers. Improving the health outcomes of residents in nursing homes requires efforts that strengthen the nursing workforce in terms of numbers and educational level, and which improve their work environment at institutional and policy levels.

The relationship between quality and staffing in long-term care: A systematic review of the literature 2008-2020

BACKGROUND

Higher staffing levels in long-term care have been associated with better outcomes for residents in several landmark studies. However previous systematic reviews found mixed results, calling into question the effectiveness of higher levels of staff. With persistent concerns about quality, rising resident acuity, and a growing demographic of seniors requiring more services, understanding the relationship between quality and long-term care staffing is a growing concern.

OBJECTIVES

This review considered the following question: What is the influence of nursing and personal care staffing levels (registered nurse, licensed practical nurse, and nursing assistant) and / or skill mix on long-term care residents, measured by quality of care indicators?

DESIGN

Preferred Reporting Items for Systematic Review and Meta-analysis Protocols guided the report of this systematic review.

DATA SOURCES

Published articles focused on quality and nursing and personal care staffing in long-term care in peer-reviewed databases (MEDLINE, CINAHL, and AGELINE) and several Cochrane databases to retrieve studies published between January 2008 and June 2020.

REVIEW METHODS

A systematic review was conducted. 11,096 studies were identified, of which 34 were included in this review. The Strengthening the Reporting of Observational Studies in Epidemiology checklist was used to evaluate study quality and risk of bias, and five quality measures were selected for in-depth analyses: pressure ulcers, hospitalizations, physical restraints, deficiencies and catherization.

RESULTS

This review confirms previous review findings that evidence on the relationships between quality and long-term care staffing level and skill mix, remain mixed. Higher staffing levels and skill mix generally supported better rather than worse outcomes. Significant and consistent findings were more evident when staffing levels were further analyzed by indicator and staffing category. For example, registered nurses were consistently associated with significantly fewer pressure ulcers, hospitalizations, and urinary tract infections. Few studies examined the impact of total nursing and personal care hours compared to the impact of specific categories or classes of nursing staff on outcomes.

CONCLUSIONS

Evidence on the relationship between quality and long-term care staffing remains mixed, however some categories of nursing staff may be more effective at improving the quality of certain indicators. Study quality has improved minimally over the last decade. Although research continues to standardize units of measurement, and longitudinal and instrumental variable analyses are increasingly being used, very few studies controlled for endogeneity, conducted adequate risk-adjustment, and used resident-level data. Additional strides must still be made to improve the rigor of long-term care staffing research.

Nurses' Work-Related Quality of Life and Its Influencing Demographic Factors at a Public Hospital in Western Iran: A Cross-Sectional Study

BACKGROUND

The quality of life as a concept beyond physical health stands one of the protuberant indexes, and various health-based studies required distinct measurements, which deemed necessary for their significant implications. The nurses fight at the front and play a leading role in providing services to patients at healthcare centers. They deserve a higher quality of life in catering to physical health services. This present study focuses on examining nurses' work-life quality standards and how demographic variables contribute to the hospital of Imam Reza in Kermanshah of Western Iran.

METHODS

This descriptive-analytical study recruited a sample of 271 nurses affiliated with Imam Reza Hospital and Kermanshah University of Medical Sciences by incorporating the stratified random sampling in 2019. This study used a two-part questionnaire to collect data from the targeted respondents. The first part presented the participants' demographic profiles, and the second part showed the nurses' work-related quality of life (WRQoL) on the scale developed by Van Laar et al. The study screened the data and performed analyses through the SPSS version-23. The research study conducted a descriptive analysis to measure mean and standard deviation with inferential statistics, including independent samples t-test and one-way ANOVA (P < 0.05).

RESULTS

The study findings specified that nurses' average quality of the work-life was at a moderate level 3.11 ± 0.47. Besides, results indicated that 57.50% of the nurses reported high standards of quality of work-life, 36.50% showed a modest and 5.20% revealed a lower level of work-life quality. The findings indicated that the quality of work-life significantly correlated with respondent'' age, marital status, education, work experience, position, department, shifts, and employment status (p < 0.05).

CONCLUSION

The findings of this research demonstrated that the nurses' quality of work-life was higher than the average standard. The results provide useful insight for nurses and hospital managers. The policymakers and health managers need to pay more attention to providing a better quality of work-life to the nurses.

Innovation to enhance health in care homes and evaluation of tools for measuring outcomes of care: rapid evidence synthesis

Background

Flexible, integrated models of service delivery are being developed to meet the changing demands of an ageing population. To underpin the spread of innovative models of care across the NHS, summaries of the current research evidence are needed. This report focuses exclusively on care homes and reviews work in four specific areas, identified as key enablers for the NHS England vanguard programme.

Aim

To conduct a rapid synthesis of evidence relating to enhancing health in care homes across four key areas: technology, communication and engagement, workforce and evaluation.

Objectives

(1) To map the published literature on the uses, benefits and challenges of technology in care homes; flexible and innovative uses of the nursing and support workforce to benefit resident care; communication and engagement between care homes, communities and health-related organisations; and approaches to the evaluation of new models of care in care homes. (2) To conduct rapid, systematic syntheses of evidence to answer the following questions. Which technologies have a positive impact on resident health and well-being? How should care homes and the NHS communicate to enhance resident, family and staff outcomes and experiences? Which measurement tools have been validated for use in UK care homes? What is the evidence that staffing levels (i.e. ratio of registered nurses and support staff to residents or different levels of support staff) influence resident outcomes?

Data sources

Searches of MEDLINE, CINAHL, Science Citation Index, Cochrane Database of Systematic Reviews, DARE (Database of Abstracts of Reviews of Effects) and Index to Theses. Grey literature was sought via Google™ (Mountain View, CA, USA) and websites relevant to each individual search.

Design

Mapping review and rapid, systematic evidence syntheses.

Setting

Care homes with and without nursing in high-income countries.

Review methods

Published literature was mapped to a bespoke framework, and four linked rapid critical reviews of the available evidence were undertaken using systematic methods. Data were not suitable for meta-analysis, and are presented in narrative syntheses.

Results

Seven hundred and sixty-one studies were mapped across the four topic areas, and 65 studies were included in systematic rapid reviews. This work identified a paucity of large, high-quality research studies, particularly from the UK. The key findings include the following. (1) Technology: some of the most promising interventions appear to be games that promote physical activity and enhance mental health and well-being. (2) Communication and engagement: structured communication tools have been shown to enhance communication with health services and resident outcomes in US studies. No robust evidence was identified on care home engagement with communities. (3) Evaluation: 6 of the 65 measurement tools identified had been validated for use in UK care homes, two of which provide general assessments of care. The methodological quality of all six tools was assessed as poor. (4) Workforce: joint working within and beyond the care home and initiatives that focus on staff taking on new but specific care tasks appear to be associated with enhanced outcomes. Evidence for staff taking on traditional nursing tasks without qualification is limited, but promising.

Limitations

This review was restricted to English-language publications after the year 2000. The rapid methodology has facilitated a broad review in a short time period, but the possibility of omissions and errors cannot be excluded.

Conclusions

This review provides limited evidential support for some of the innovations in the NHS vanguard programme, and identifies key issues and gaps for future research and evaluation.

Future work

Future work should provide high-quality evidence, in particular experimental studies, economic evaluations and research sensitive to the UK context.

Process, structural, and outcome quality indicators of nutritional care in nursing homes: a systematic review

Background

The quality of nursing homes (NHs) has attracted a lot of interest in recent years and is one of the most challenging issues for policy-makers. Nutritional care should be considered an important variable to be measured from the perspective of quality management. The aim of this systematic review is to describe the use of structural, process, and outcome indicators of nutritional care in NHs and the relationship among them.

Methods

The literature search was carried out in Pubmed, Embase, Scopus, and Web of Science. A temporal filter was applied in order to select papers published in the last 10 years. All types of studies were included, with the exception of reviews, conference proceedings, editorials, and letters to the editor. Papers published in languages other than English, Italian, and Spanish were excluded.

Results

From the database search, 1063 potentially relevant studies were obtained. Of these, 19 full-text articles were considered eligible for the final synthesis. Most of the studies adopted an observational cross-sectional design. They generally assessed the quality of nutritional care using several indicators, usually including a mixture of many different structural, process, and outcome indicators. Only one of the 19 studies described the quality of care by comparing the results with the threshold values. Nine papers assessed the relationship between indicators and six of them described some significant associations—in the NHs that have a policy related to nutritional risk assessment or a suitable scale to weigh the residents, the prevalence or risk of malnutrition is lower. Finally, only four papers of these nine included risk adjustment. This could limit the comparability of the results.

Conclusion

Our findings show that a consensus must be reached for defining a set of indicators and standards to improve quality in NHs. Establishing the relationship between structural, process, and outcome indicators is a challenge. There are grounds for investigating this theme by means of prospective longitudinal studies that take the risk adjustment into account.

Relationship of Employees' Achievement Motivation and Quality of Working Life with Their Self-efficacy at Selected Hospitals with a Multi-group Analysis: Moderating Role of Organizational Ownership

Introduction:

Motivational deficiencies and the low quality of working life significantly reduce employees’ work performance and consequently their efficacy (effectiveness and proper performance in doing a task or specific tasks).

Aim:

The aim of this study was to determine the relationship between achievement motivation and quality of working life with self-efficacy among staff working in Mazandaran hospitals, by taking organizational ownership as a mediator variable.

Materials and Methods:

This study was an applied descriptive-correlation. Research population consisted of all staff working in selected hospitals of Mazandaran Province, Iran. 341 employees were selected with randomly-stratified sampling as the statistical sample. Three valid questionnaires were used for data collection. Data were analysis based on structured equations and path analysis with SPSS19 and AMOS.

Results:

In private hospitals, there was a significant relationship between the quality of working life and self-efficacy (p<0.001). In relationship between achievement motivation and self-efficacy, there was no significant differences between university hospitals and social security hospitals, but relationship between the quality of working life and self-efficacy was significant (p <0. 05). Considering achievement motivation and self-efficacy in private hospitals and university hospitals, a significant differences was observed (p<0. 05).

Conclusion:

The hospital ownership has a moderating in relationship of achievement motivation and quality of working life with self-efficacy. Staff’s empowerment courses for university hospitals and improvement in the overall space of job, increase in job security, reducing salary differences is suggested for private hospitals.

Professional care providers in dementia care in eight European countries; their training and involvement in early dementia stage and in home care

Knowledge concerning professionals involved in dementia care throughout its trajectory is sparse; the focus has mainly been on nursing-home care and less on home care, diagnosis and treatment of the disease and its complications despite the fact that home care is the most prominent type of care. The aim of this study was to explore and describe professional care providers involved in dementia care and their educational level applying the International Standard Classification of Education (ISCED) and further to investigate practice in the RightTimePlaceCare-countries with regard to screening, diagnostic procedures and treatment of dementia and home care. The findings demonstrate more similarities than differences in terms of type of professionals involved among the countries although untrained staff were more common in some countries. Findings also show that many types of professionals are involved, who to turn to may not be clear, for instance in terms of medical specialities and it may be unclear who bears the ultimate responsibility. The professionals involved in diagnosis, treatment and care are educated to bachelor’s level or above whilst everyday care is provided by people trained at a lower ISCED level or with no formal training. Registered nurses as well as occupational therapists have bachelor’s degrees in most countries, but not in Germany or Estonia. Professionals specifically trained in dementia care are not so common. Further research is needed to reveal not only who provides the diagnostics and treatment, but also how home care is organised and quality assured. Many different types of professionals serve as providers along the trajectory of the disease which may be difficult for the patient and the informal caregiver to cope with.

Structural characteristics of specialised living units for people with dementia: a cross-sectional study in German nursing homes

Background

Living units (LU) specialised for people with dementia are an important feature of nursing homes. Little is known about their structural characteristics, and an international definition is lacking. This study explored characteristics of the environment and staff from defined LU types to identify differences between them.

Design

Cross-sectional study comparing five types of LUs. LUs were defined based on their living concept (segregated and integrated), size (small and large scale), and funding (extra funded and not extra funded). Differences were identified using descriptive statistics, Chi-Square resp. Kruskal-Wallis-Test and post-hoc analysis with Bonferroni corrections.

Results

In total, 103 LUs from 51 nursing homes participated: 63 integrated and 40 segregated LUs; 48 integrated and 31 segregated LUs were large. Sixteen large segregated LUs were extra funded. Regarding the environment, a distinctive feature of small LUs was a higher percentage of single rooms. Small integrated LUs provided and served meals more in a homelike manner than other LUs. LUs did not differ in their interior and access for the residents to use outdoor areas. Regarding the staff, small LUs provided more staff, but they were not exclusively assigned to the LUs. Large segregated LUs with additional funding provided more registered nurses and nurses with a special qualification per resident than the other large LUs.

Conclusion

Nursing homes implemented different features in their specialised LUs. Because single room availability, homelike provision of meals, staff quantity, quality and continuity may influence residents’ outcomes, it is necessary to investigate whether differences are apparent in future evaluation studies of specialised LUs for people with dementia.
