Epidemiology and assessments of delirium in nursing homes and rehabilitation facilities: a cross-country perspective

PURPOSE

Delirium represents a significant healthcare challenge in long-term care settings. This study aims to investigate the epidemiology of delirium in long-term care facilities (LTCFs) across various countries, examining point prevalence and assessment methods.

METHODS

This descriptive analysis included data from 94 surveys conducted in LTCFs on World Delirium Awareness Day (WDAD), March 15th, 2023. Group comparisons were made between rehabilitation facilities (RFs) and nursing homes (NHs).

RESULTS

Of the participating units/wards, primarily from Europe and Australia, 65 were RFs and 29 were NHs. The overall reported delirium point prevalence was approximately 12%, with higher rates in RFs than in NHs. While most units/wards reported using a validated delirium detection tool, notable differences emerged in the frequency of assessments, the personnel conducting them, and delirium awareness interventions across settings.

CONCLUSION

Despite the well-documented impact of delirium on residents, the international variability in clinical practices within LTCFs highlights the current inadequacy in adopting effective and consistent strategies to address this condition.

Organizational Context and Facilitation Interactions on Delirium Risk in Long-Term Care: A Cross-Sectional Study

OBJECTIVES

Organizational context (eg, leadership) and facilitation (eg, coaching behaviors) are thought to interact and influence staff best practices in long-term care (LTC), including the management of delirium. Our objective was to assess if organizational context and facilitation-individually, and their interactions-were associated with delirium in LTC.

DESIGN

Retrospective cross-sectional analysis of secondary data.

SETTING AND PARTICIPANTS

We included 8755 residents from 281 care units in 86 LTC facilities in 3 Canadian provinces.

METHODS

Delirium (present/absent) was assessed using the Resident Assessment Instrument-Minimum Data Set 2.0 (RAI-MDS 2.0). The Alberta Context Tool (ACT) measured 10 modifiable features of care unit organizational context. We measured the care unit's total care hours per resident day and the proportion of care hours that care aides contributed (staffing mix). Facilitation included the facility manager's perception of RAI-MDS reports' adequacy and pharmacist availability. We included unit managers' change-oriented organizational citizenship behavior (OCB) and an item reflecting how often care aides recommended policy changes. Associations of organizational context, facilitation, and their interactions with delirium were analyzed using mixed-effects logistic regressions, controlling for covariates.

RESULTS

Delirium symptoms were prevalent in 17.4% of residents (n = 1527). Manager-perceived adequacy of RAI-MDS reports was linked to reduced delirium symptoms [odds ratio (OR) = 0.63]. Higher care hours per resident day (OR = 1.2) and an available pharmacist in the facility (OR = 1.5) were associated with increased delirium symptoms. ACT elements showed no direct association with delirium. However, on care units with low social capital scores (context), increased unit managers' OCB decreased delirium symptoms. On care units with high vs low evaluation scores (context), increased staffing mix reduces delirium symptoms more substantially.

CONCLUSIONS AND IMPLICATIONS

Unit-level interactions between organizational context and facilitation call for targeted quality improvement interventions based on specific contextual factors, as effectiveness may vary across contexts.

Preventing, identifying and managing delirium in nursing homes and acute settings

Older people, particularly those in nursing homes, are vulnerable to delirium, which is a condition characterised by confusion. This article outlines the risk factors, prevention, identification and management of delirium in older people in nursing homes and acute settings. It uses a case study approach to encourage nurses to consider the challenges faced in these settings and how they could address delirium. The article also details the multicomponent interventions that can be used for prevention, as well as the available delirium assessment tools, with a focus on selecting tools based on the person's health status and the healthcare setting.

Development and Evaluation of Clinical Practice Guideline for Delirium in Long-Term Care

Delirium is highly prevalent and leads to several bad outcomes for older long-term care (LTC) residents. For a more successful translation of delirium knowledge, Clinical Practice Guidelines (CPGs) tailored to LTC should be developed and applied based on the understanding of the barriers to implementation. This study was conducted to develop a CPG for delirium in LTC and to determine the barriers perceived by healthcare professionals related to the implementation of the CPG. We followed a structured, evidence- and theory-based procedure during the development process. After a systematic search, quality appraisal, and selection for eligible up-to-date CPGs for delirium, the recommendations applicable to the LTC were drafted, evaluated, and confirmed by an external group of experts. To evaluate the barriers to guideline uptake from the users' perspectives, semi-structured interviews were conducted which resulted in four major themes: (1) a lack of resources, (2) a tendency to follow mindlines rather than guidelines, (3) passive attitudes, and (4) misunderstanding delirium care in LTC. To minimize adverse prognoses through prompt delirium care, the implementation of a CPG with an approach that comprehensively considers various barriers at the system, practice, healthcare professional, and patients/family levels is necessary.
