Non-pharmacological interventions to prevent and treat delirium in older people: An overview of systematic reviews

Exploring academic and clinical nurses' perspectives on evidence-based nursing course for undergraduates from perspectives of academic-practice partnerships: a qualitative study

AIM

To explore nurses' perceptions of evidence-based nursing courses for undergraduates through academic-practice partnerships.

DESIGN

A deductive thematic analysis based on the practice-academic logic model.

METHODS

Fifteen academic and clinical nurses were interviewed between November and December 2023, either online or through face-to-face meetings. Each interview lasted 20-30 min. The interview outline was constructed based on the practice-academic partnership logic model, which was followed during the process of recorded, analyzed, and checked.

RESULTS

Themes identified include inputs (e.g., stakeholder commitment), activities (e.g., communication), outputs (e.g., nursing projects), and outcomes (e.g., improved competence). These themes highlight the various aspects and outcomes of academic-practice partnerships in evidence-based nursing courses.

CONCLUSION

Effective academic-practice partnerships are crucial for developing evidence-based nursing courses, leading to positive educational and professional outcomes.

IMPACT

Nurses' perceptions provide valuable guidelines for developing effective evidence-based nursing courses.

Cognitive and functional change in skilled nursing facilities: Differences by delirium and Alzheimer's disease and related dementias

BACKGROUND

Whether cognitive and functional recovery in skilled nursing facilities (SNF) following hospitalization differs by delirium and Alzheimer's disease related dementias (ADRD) has not been examined.

OBJECTIVE

To compare change in cognition and function among short-stay SNF patients with delirium, ADRD, or both.

DESIGN

Retrospective cohort study using claims data from 2011 to 2013.

SETTING

Centers for Medicare and Medicaid certified SNFs.

PARTICIPANTS

A total of 740,838 older adults newly admitted to a short-stay SNF without prevalent ADRD who had at least two assessments of cognition and function.

MEASUREMENTS

Incident delirium was measured by the Minimum Data Set (MDS) Confusion Assessment Method and ICD-9 codes, and incident ADRD by ICD-9 codes and MDS diagnoses. Cognitive improvement was a better or maximum score on the MDS Brief Interview for Mental Status, and functional recovery was a better or maximum score on the MDS Activities of Daily Living Scale.

RESULTS

Within 30 days of SNF admission, the rate of cognitive improvement in patients with both delirium/ADRD was half that of patients with neither delirium/ADRD (HR = 0.45, 95% CI:0.43, 0.46). The ADRD-only and delirium-only groups also were 43% less likely to have improved cognition or function compared to those with neither delirium/ADRD (HR = 0.57, 95% CI:0.56, 0.58 and HR = 0.57, 95% CI:0.55, 0.60, respectively). Functional improvement was less likely in patients with both delirium/ADRD, as well (HR = 0.85, 95% CI:0.83, 0.87). The ADRD only and delirium only groups were also less likely to improve in function (HR = 0.93, 95% CI:0.92, 0.94 and HR = 0.92, 95% CI:0.90, 0.93, respectively) compared to those with neither delirium/ADRD.

CONCLUSIONS

Among older adults without dementia admitted to SNF for post-acute care following hospitalization, a positive screen for delirium and a new diagnosis of ADRD, within 7 days of SNF admission, were both significantly associated with worse cognitive and functional recovery. Patients with both delirium and new ADRD had the worst cognitive and functional recovery.

Effectiveness of nurse-led non-pharmacological interventions on outcomes of delirium in adults: A meta-analysis of randomized controlled trials

BACKGROUND

Delirium is a common complication among adults. It is essential to improve the outcomes of delirium.

AIM

To systematically synthesize the evidence on the effectiveness of the nurse-led non-pharmacological interventions on outcomes of delirium in adults.

METHODS

Electronic databases including CINAHL, Cochrane Library, MEDLINE, EMBASE, PubMed, Web of Science, PsycINFO, and Clinical Trial Registration were searched comprehensively by the authors. The authors reviewed the full text and assessed the risk of bias using the Cochrane Risk of Bias Tool 2.0. The meta-analysis was performed using RevMan and Stata software. The forest plots showed the overall effect of the included study and the I2 test was used to assess the degree of heterogeneity between studies. Random effects models were used to analyze studies with significant heterogeneity.

RESULTS

A total of 32 studies (10,122 participants) were included in the meta-analysis. Nurse-led non-pharmacological interventions resulted in a significantly lower incidence of delirium compared with the usual care/control group (risk ratio = 0.74, p < .001) and reduced mortality in the hospital compared with usual care (risk ratio = 0.81, p = .04). However, the implementation of nurse-led, non-pharmacological interventions had no significant effect on the duration, severity of delirium, or length of hospital stay.

LINKING EVIDENCE TO ACTION

Our findings suggest that the nurse-led, non-pharmacological strategy was effective in reducing the incidence of delirium and mortality in the hospital. Multicomponent interventions were the most effective strategy for reducing the incidence of delirium in adults.

Development of a complex intervention to prevent delirium in older hospitalized patients by optimizing discharge and transfer processes and involving caregivers: A multi-method study

BACKGROUND

Delirium is a common yet challenging condition in older hospitalized patients, associated with various adverse outcomes. Environmental factors, such as room changes, may contribute to the development or severity of delirium. Most previous research has focused on preventing and reducing this condition by addressing risk factors and facilitating reorientation during hospital stay.

OBJECTIVE

We aimed to systematically develop a complex intervention to prevent delirium in older hospitalized patients by optimizing discharge and transfer processes and involving caregivers during and after these procedures. The intervention combines stakeholder and expert opinions, evidence, and theory. This article provides guidance and inspiration to research groups in developing complex interventions according to the recommendations in the Medical Research Council framework for complex interventions.

DESIGN AND METHODS

A stepwise multi-method study was conducted. The preparation phase included analysis of the context and current practice via focus groups. Based on these results, an expert workshop was organized, followed by a Delphi survey. Finally, the intervention was modeled and a program theory was developed, including a logic model.

RESULTS

A complex intervention was developed in an iterative process, involving healthcare professionals, delirium experts, researchers, as well as caregiver and patient representatives. The key intervention component is an 8-point-program, which provides caregivers with recommendations for preventing delirium during the transition phase and in the post-discharge period. Information materials (flyers, handbook, videos, posters, defined "Dos and Don'ts", discharge checklist), training for healthcare professionals, and status analyses are used as implementation strategies. In addition, roles were established for gatekeepers to act as leaders, and champions to serve as knowledge multipliers and trainers for the multi-professional team in the hospitals.

CONCLUSIONS

This study serves as an example of how to develop a complex intervention. In an additional step, the intervention and implementation strategies will be investigated for feasibility and acceptability in a pilot study with an accompanying process evaluation.

TWEETABLE ABSTRACT

Delirium prevention can benefit from optimizing discharge and transfer processes and involving caregivers of older patients in these procedures.
