Diagnosis and Risk Factors for Delirium in Elderly Patients in the Emergency Rooms and Intensive Care Unit of the National Geriatric Hospital Emergency Department: A Cross-Sectional Observational Study

A survey of non-consultant hospital doctors' perspectives, knowledge, and practices toward delirium in a large Irish hospital

BACKGROUND

Delirium is a common condition in hospitals, particularly among older people. This refers to a dramatic decline in mental capabilities, which is marked by diminished concentration and consciousness.

AIM

The purpose of this study was to assess the views, knowledge, and behavior of non-consultant hospital doctors in managing delirium in a large Irish hospital.

METHODS

Questionnaires were administered to 28 healthcare professionals from various departments according to Davis and MacLullich (Age Ageing 38(5):559-563, 2009). It was conducted between July and September 2023, with an emphasis on determining the prevalence rate, diagnostic criteria, and management strategies for delirium.

RESULTS

The study established that the majority of respondents recognized the importance of delirium, but there appears to be a gap in the practical management of this clinical syndrome. Although many doctors agreed that delirium was significant, most lacked confidence in its diagnosis and management. The use of standardized assessment tools, such as the 4AT, was limited.

CONCLUSIONS

This study highlights the disparity between what is known and practiced by hospital doctors regarding delirium care. This implies increased training for delirium management with frequent use of assessment tools and ongoing education aimed at enhancing patient outcomes in cases of delirium.

Nutrition care for older adults with delirium: A scoping review

AIMS

This scoping review aimed to identify and map the available information on the nutrition care process in older adults with delirium to analyse and summarise key concepts, and gaps, including the barriers and enablers to providing nutrition care for this group.

DESIGN

Scoping review.

METHODS

This review was conducted in accordance with the JBI methodology for scoping reviews. Published and grey sources in English were considered.

DATA SOURCES

Databases searched were CINAHL, Medline, Embase, JBI Evidence-based Practice, Scopus, ProQuest and Google. The initial search was conducted from October 2021 to March 2022 and repeated in October 2023.

RESULTS

The database search identified 1561 articles, 186 underwent full-text review and 17 articles were included. The grey literature search identified eight articles. Malnutrition and delirium were identified as mutually reinforcing, and nutrition strategies were included as part of multicomponent interventions for delirium management. There was no mention of barriers or enablers to nutrition care and minimal descriptive or empirical data available to guide nutrition care processes in this group.

CONCLUSION

This scoping review revealed a need for further research into nutrition care processes in older patients with delirium, in particular the barriers and enablers, to inform appropriate management strategies in this vulnerable group.

IMPLICATIONS FOR THE PROFESSION AND PATIENT CARE

Providing nutrition care for older patients with delirium is important and further practical guidance could help patients, healthcare staff and families.

IMPACT

This scoping review yielded instructive data suggesting that delirium is an important risk factor for malnutrition and vice versa, which leads to poor patient and health service outcomes.

REPORTING METHOD

This scoping review adhered to relevant EQUATOR guidelines and used the Preferred Reporting Items For Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR).

Effect of using eye masks and earplugs in preventing delirium in intensive care patients: A single-blinded, randomized, controlled trial

BACKGROUND

Delirium, which is frequently encountered in intensive care patients, can be prevented with multicomponent nursing interventions, and thus the negative consequences can be reduced.

AIM

To examine the effect of using eye masks and earplugs in preventing delirium in intensive care units (ICUs).

STUDY DESIGN

A randomized, controlled, single-blind intervention study. This study was conducted in the medical and surgical ICUs of a tertiary hospital, and nurses were given pre-study training on delirium risks, diagnosis, prevention, and management. Data were collected using the patient information form, the Nursing Delirium Screening Scale, the Richard-Campbell Sleep Scale, and the daily follow-up form. Various environmental modifications were made in the ICUs for all patients, and evidence-based nonpharmacological nursing interventions were applied to the patients in both groups during the day and night shifts for 3 days. In addition, the patients in the intervention group were provided with eye masks and earplugs for three nights.

RESULTS

The study included a total of 60 patients (30 in the intervention group and 30 in the control group). There was a statistically significant difference in the development of delirium between the intervention and control groups (night of the 2nd day, p = .019; day of the 3rd day p < .001; night of the 3rd day p ≤ .001). The average total sleep quality score of the intervention group was found to be significantly higher than the control group (p ≤ .001 for three nights). Staying in the internal medicine ICU affected (odds ratio [OR], 11.84; 95% confidence interval [CI], 3.00-46.66; p = .017) more on the development of delirium than in coronary ICU, being in the age group of 65 and over, having a hearing impairment, coming to ICU from the operating room, and education level had an effect.

CONCLUSIONS

The earplugs and eye masks used by the intensive care patients overnight were found to be effective in increasing sleep quality and preventing delirium.

RELEVANCE TO CLINICAL PRACTICE

The use of eye masks and earplugs is recommended for ICUs in preventing delirium.

Validation to Spanish of nursing assessment scale for early diagnosis of delirium - Nu-DESC

Objective

This work aimed to determine the validity and reliability of the Colombian Spanish version of the Nursing Delirium Screening Scale (Nu-DESC).

Methods

A psychometric study was conducted to achieve the goal of this study, which measured face validity, content validity, sensitivity, specificity and predictive values of the Nu-DESC.

Results

. Face validity obtained a total Aiken V of 0.89, and content validity showed a modified Lawshe index of 0.92. When Nu-DESC was applied to 210 adult patients hospitalized in the Intensive Care Unit, it was found that 14.2% had suspected delirium. The instrument showed a sensitivity of 91.6%, specificity of 95.6%, positive predictive value of 73.3%, negative predictive value of 98.8%, good internal consistency with Cronbach's α of 0.8 and good concordance according to Cohen's Kappa index of 0.788.

Conclusion

The Spanish version of the Nu-DESC scale for Colombia has appropriate psychometric values for assessing delirium risk. In addition, this scale is easy to apply, so the adaptation of nursing personnel for its employability favors routine monitoring and timely detection of delirium.

Non-Pharmacological Nursing Interventions to Prevent Delirium in ICU Patients-An Umbrella Review with Implications for Evidence-Based Practice

Delirium in ICU patients is a complication associated with many adverse consequences. Given the high prevalence of this complication in critically ill patients, it is essential to develop and implement an effective management protocol to prevent delirium. Given that the cause of delirium is multifactorial, non-pharmacological multicomponent interventions are promising strategies for delirium prevention. (1) Background: To identify and evaluate published systematic review on non-pharmacological nursing interventions to prevent delirium in intensive care unit patients. (2) Methods: An umbrella review guided by the Joanna Briggs Institute was utilized. Data were obtained from PubMed, Scopus, EBSCO, Web of Science, Cochrane Library, and Google Scholar. The last search was conducted on 1 May 2022. (3) Results: Fourteen reviews met the inclusion criteria. Multicomponent interventions are the most promising methods in the fight against delirium. The patient's family is an important part of the process and should be included in the delirium prevention scheme. Light therapy can improve the patient's circadian rhythm and thus contribute to reducing the incidence of delirium. (4) Conclusions: Non-pharmacological nursing interventions may be effective in preventing and reducing the duration of delirium in ICU patients.
