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.

Exploring influential factors on patient safety culture in delirium nursing care within long-term care facilities: a cross-sectional survey

BACKGROUND

Elderly residents with physical and cognitive impairments in long-term care facilities are vulnerable to safety risks.

PURPOSE

This study investigated factors that influence patient safety cultures in delirium nursing care in long-term care facilities.

METHODS

A cross-sectional survey was conducted among 214 nurses working in 12 long-term care facilities using a structured questionnaire from February 15, 2022, to March 14, 2022. Data analysis was performed using Pearson's correlation coefficients and hierarchical analysis with SPSS/WIN 25.0 software.

RESULTS

Significant factors associated with patient safety culture were identified. Organizational factors included the availability of delirium care manuals, nursing education and experience in delirium care, and the perceived necessity of delirium education. Individual factors included nurse-to-patient ratios, and nurses marital status.

CONCLUSION

To foster a strong patient safety culture, attention should be given to the availability of delirium care resources, the promotion of specialized and ongoing education and experience, and adequate staffing levels.
