An evaluation of a national program to implement the Cornell Scale for Depression in Dementia into routine practice in aged care facilities

The External Validation of the Nursing Homes Short Depression Inventory in Older Adults with Major Neurocognitive Disorders in Long-Term Care Centers

INTRODUCTION

Depression is often difficult to detect in long-term care (LTC) patients with major neurocognitive disorders (MNCD), and an observer-rated screening scale could facilitate assessments. This study aimed to establish the external validity and reliability of the Nursing Homes Short Depression Inventory (NH-SDI) in LTC patients with MNCD and to compare its estimates to the Cornell Scale for Depression in Dementia (CSDD), the most used scale for depression in MNCD.

METHODS

A focus discussion group of experts assessed the content validity of the NH-SDI. Then, a convenience sample of 93 LTC patients with MNCD was observer-rated by trained nurses with the NH-SDI and CSDD. For 57 patients, a medical assessment of depression was obtained, and screening accuracy estimates were generated.

RESULTS

The prevalence of depression was 8.8% as per reference standard. NH-SDI's content validity was judged acceptable with minor item wording modifications and specifications. The NH-SDI (cut-off ≥3) achieved 100% (95% confidence interval [CI]: 46-100%) sensitivity, 83% (95% CI: 69-91%) specificity, and 36% (95% CI: 14-64%) positive predictive value (PPV). The CSDD (cut-off ≥3) achieved 100% (95% CI: 46-100%) sensitivity, 75% (95% CI: 61-86%) specificity, and 28% (95% CI: 11-54%) PPV. No significant differences in areas under the receiver operating characteristic curve were found between scales. The NH-SDI and CSDD were highly correlated (rs = 0.913; p < 0.001) and reliable (ICC = 0.77; p < 0.001).

CONCLUSION

The NH-SDI appears valid and reliable in LTC patients with MNCD and quicker than the CSDD to rule out depression in a busy or short-staffed setting.

Trajectory and Predictors of Mental Health Symptoms and Wellbeing in Newly Admitted Nursing Home Residents

OBJECTIVES

This study determined changes in multiple aspects of mental health and wellbeing in newly admitted nursing home residents, and identified risk and protective factors.

METHODS

Participants were 204 residents recently admitted to one of 42 nursing homes in Melbourne, Australia. A subgroup of 82 participants were followed up eight months post-admission. Depression, anxiety, stress, adjustment, and quality of life were assessed at baseline and follow-up. Predictive factors (demographics, health, transition factors, nursing home characteristics) were examined in multiple regression analyses.

RESULTS

Rates of depression and anxiety were high at both baseline and follow-up. Low self-rated health and medical comorbidity predicted poor wellbeing at baseline. Higher perceived control in the relocation to the nursing home and engagement in meaningful activities were associated with better post-admission outcomes. Baseline psychotropic medication use predicted lower anxiety at follow-up but did not impact depressive symptoms.

CONCLUSIONS

There were no significant changes in mental health and wellbeing from one to eight months post-admission. The negative effect of residing in a for-profit nursing home requires further investigation.

CLINICAL IMPLICATIONS

Individual activity scheduling and an opportunity to participate in relocation decision-making and planning may support resident wellbeing post-admission.

The effectiveness of the Program to Enhance Adjustment to Residential Living (PEARL) in reducing depression in newly admitted nursing home residents

BACKGROUND

Depression is common in nursing homes, particularly among newly admitted residents. This cluster randomised controlled trial evaluated the effectiveness of the Program to Enhance Adjustment to Residential Living (PEARL) in reducing depression in this group.

METHODS

Participants were 219 newly-admitted residents (mean of 4.4 weeks since admission) in 42 nursing homes in Melbourne, Australia, with a mean age of 85.5 years (SD = 7.3). Nursing homes were randomly allocated to the intervention or standard care condition. Level of depressive symptoms was evaluated at baseline (T1), one week post- intervention (T2), 2 months post-intervention (T3, primary end point), and 6 months post-intervention (T4). Changes in depressive symptoms in the intervention and control groups over time were compared using a multilevel model, with nursing homes modelled as random intercept.

RESULTS

In intention to treat analyses, depressive symptoms reduced from T1 to T3 to a greater degree in the intervention condition (M_change=2.56, SD_change=5.71) than in the control (M_change=0.63, SD_change=5.25), with a significant, small-medium treatment effect size (p=.035; Cohen's d=0.36). The reduction in depressive symptoms from T1 to T4 was not significant (p=.369; Cohen's d=0.32).

LIMITATIONS

The findings require replication, particularly comparing PEARL with an active control condition.

CONCLUSIONS

PEARL is a simple, brief program that was effective in reducing symptoms of depression in newly admitted nursing home residents.

Measuring the impact of system level strategies on psychotropic medicine use in aged care facilities: A scoping review

BACKGROUND

Psychotropic medication use in the elderly population is associated with significant adverse effects. Robust evidence for the efficacy of psychotropic medications for behavioural and psychological symptoms of dementia is lacking. Despite national bodies, governments, and policymakers employing interventions to optimise the use of psychotropic medicines in this population, there is little research on their overall impact.

OBJECTIVE

To identify and categorise system level strategies that have been implemented internationally and assess their impact on psychotropic medicine use in aged care facilities.

METHODS

A systematic search of health-related databases including Medline, Embase, CINAHL, Web of Science and Scopus was performed. Empirical studies published in English prior to March 2019 that reported on the impact of system level strategies on psychotropic medicine use in aged care facilities were included. Studies were mapped to the RE-AIM (Reach, Effectiveness, Adoption, Implementation, Maintenance) framework to measure impact and were assessed for risk of bias.

RESULTS

This review identified 36 studies which examined mandatory (n = 22) and non-mandatory (n = 14) system level strategies. The impact of strategies was highly dependent on implementation as well as organisational and patient factors. Mandatory strategies had greater evidence of impact on drug utilisation patterns compared to non-mandatory strategies which primarily focussed on adoption and implementation, rather than outcomes. The Omnibus Budget Reconciliation Act 1987 (OBRA-87) in the United States of America had the greatest reach and implementation of the interventions examined, with an observed reduction in psychotropic medicine use post-implementation. There was no substantive body of evidence reporting on the sustainability of strategies or the influence of cost on outcomes.

CONCLUSIONS

Despite the implementation of system level strategies, psychotropic medicine use in aged care facilities remains problematic. There is a need for revised or novel system level strategies which consider sustainability, economic influences and patient outcomes in their design and implementation.

The prevalence, reporting, and treatment of anxiety among older adults in nursing homes and other residential aged care facilities

BACKGROUND

Little is known about anxiety in aged care populations, despite its increase in this frail population. This study investigated the prevalence, recording, and treatment rate of anxiety disorders among aged care residents.

METHODS

A cross-sectional, observational design was used to assess 180 elderly residents from 12 aged care facilities in Melbourne, Australia. Participants were assessed for threshold and subthreshold anxiety disorders and comorbid depression using the MINI for DSM-5. Medical files were also reviewed to determine whether there was any indication that anxiety had previously been detected, and what treatment those with a threshold/subthreshold diagnosis were receiving.

RESULTS

Overall prevalence of threshold and subthreshold anxiety disorders was 19.4% and 11.7%, respectively. Generalized anxiety disorder was the most common threshold disorder and agoraphobia was the most prevalent subthreshold anxiety disorder. While less than half of those with a threshold or subthreshold anxiety disorder had an indication of anxiety in their file, the majority received psychotropic medication. Cognitive impairment was not significantly associated with the prevalence or treatment of anxiety.

CONCLUSIONS

The prevalence of threshold and subthreshold anxiety in aged care settings is high, but remains under-reported by staff and GPs. Facility staff and GPs should ensure they are aware of how anxiety presents in elderly residents and routinely screen for this common mental health issue. This cohort had poor access to psychological treatments for their condition.

A pilot trial of acceptance and commitment therapy for symptoms of depression and anxiety in older adults residing in long-term care facilities

OBJECTIVES

The aim of this study was to evaluate the efficacy and acceptability of a psychological intervention based on acceptance and commitment therapy (ACT) to improve symptoms of depression and anxiety among older adults living in long-term care.

METHOD

Forty one residents aged between 63 and 97 years (M = 85.3 years) participated in this study. Residents were allocated to receive either a 12 session ACT intervention implemented by trainee psychology therapists or a wait-list control group. Measures of depression and anxiety were collected at baseline and 8 week post-intervention, and residents who received the intervention were tracked for three months. A treatment satisfaction questionnaire was administered to residents who received the intervention and a sample of 10 facility staff members.

RESULTS

Using an intention to treat approach and controlling for baseline scores, scores on depression measures were significantly lower after the ACT intervention than after the wait-list control. These outcomes were maintained at three-month follow-up. Treatment satisfaction was rated highly by both residents and their care staff.

CONCLUSION

This preliminary trial suggests that ACT shows promise as a therapeutic approach to address symptoms of depression in long-term care.

Validity of the geriatric depression scale and the collateral source version of the geriatric depression scale in nursing homes

BACKGROUND

Depression is a common psychiatric disorder in older people. The study aimed to examine the screening accuracy of the Geriatric Depression Scale (GDS) and the Collateral Source version of the Geriatric Depression Scale (CS-GDS) in the nursing home setting.

METHODS

Eighty-eight residents from 14 nursing homes were assessed for depression using the GDS and the CS-GDS, and validated against clinician diagnosed depression using the Semi-structured Clinical Diagnostic Interview for DSM-IV-TR Axis I Disorders (SCID) for residents without dementia and the Provisional Diagnostic Criteria for Depression in Alzheimer Disease (PDCdAD) for those with dementia. The screening performances of five versions of the GDS (30-, 15-, 10-, 8-, and 4-item) and two versions of the CS-GDS (30- and 15-item) were analyzed using receiver operating characteristic (ROC) curves.

RESULTS

Among residents without dementia, both the self-rated (AUC = 0.75-0.79) and proxy-rated (AUC = 0.67) GDS variations performed significantly better than chance in screening for depression. However, neither instrument adequately identified depression among residents with dementia (AUC between 0.57 and 0.70). Among the GDS variations, the 4- and 8-item scales had the highest AUC and the optimal cut-offs were >0 and >3, respectively.

CONCLUSIONS

The validity of the GDS in detecting depression requires a certain level of cognitive functioning. While the CS-GDS is designed to remedy this issue by using an informant, it did not have adequate validity in detecting depression among residents with dementia. Further research is needed on informant selection and other factors that can potentially influence the validity of proxy-based measures in the nursing home setting.

The clinical utility of the Cornell Scale for Depression in Dementia as a routine assessment in nursing homes

OBJECTIVE

To examine the clinical utility of the Cornell Scale for Depression in Dementia (CSDD) in nursing homes.

SETTING

14 nursing homes in Sydney and Brisbane, Australia.

PARTICIPANTS

92 residents with a mean age of 85 years.

MEASUREMENTS

Consenting residents were assessed by care staff for depression using the CSDD as part of their routine assessment. Specialist clinicians conducted assessment of depression using the Semi-structured Clinical Diagnostic Interview for DSM-IV-TR Axis I Disorders for residents without dementia or the Provisional Diagnostic Criteria for Depression in Alzheimer Disease for residents with dementia to establish expert clinical diagnoses of depression. The diagnostic performance of the staff completed CSDD was analyzed against expert diagnosis using receiver operating characteristic (ROC) curves.

RESULTS

The CSDD showed low diagnostic accuracy, with areas under the ROC curve being 0.69, 0.68 and 0.70 for the total sample, residents with dementia and residents without dementia, respectively. At the standard CSDD cutoff score, the sensitivity and specificity were 71% and 59% for the total sample, 69% and 57% for residents with dementia, and 75% and 61% for residents without dementia. The Youden index (for optimizing cut-points) suggested different depression cutoff scores for residents with and without dementia.

CONCLUSION

When administered by nursing home staff the clinical utility of the CSDD is highly questionable in identifying depression. The complexity of the scale, the time required for collecting relevant information, and staff skills and knowledge of assessing depression in older people must be considered when using the CSDD in nursing homes.

Improving delirium care for hospitalized older patients. A qualitative study identifying barriers to guideline adherence

RATIONALE, AIMS AND OBJECTIVES

Guidelines are intended as a means of getting research evidence into practice and ensuring provided care is of sufficient quality. However, the effect of guidelines is hindered by limited guideline adherence. The aim of this study is to identify and classify barriers to adherence by nurses to a guideline on delirium care.

METHODS

Open-ended interviews were conducted with a purposive sample of 63 research participants. The sample included 28 nurses, 18 doctors and 17 policy advisors working in 19 hospitals in the Netherlands. The interviews were conducted between June and September 2011. The data were analysed using thematic analysis.

RESULTS

Barriers to guideline adherence that were identified could be grouped into four themes: motivation and goals, knowledge and skills, professional role and identity, and context and resources. While the interviews with nurses, doctors and policy advisors produced similar views of the current situation, doctors and policy advisors placed a higher importance on education as a means of stimulating adherence.

CONCLUSIONS

This study illustrates that individual, social and organizational factors play a role in nurse's adherence to a delirium guideline. The potential benefits of following a guideline, both for patients and for nursing staff, need to be highlighted in order to motivate nurses. When formulating new guidelines, nurses' perceptions of their professional role and patient care need to be taken into account to ensure that policy makers and managers are realistic about guideline adherence and engage with nurses from a position of mutual respect and trust.

Staff-focused interventions to increase referrals for depression in aged care facilities: a cluster randomized controlled trial

OBJECTIVE

While there is evidence that depression training can improve the knowledge of staff in residential care facilities, there is an absence of research determining whether such training translates into practice change. This study aimed to evaluate the impact of staff training and the introduction of a protocol for routine screening and referral for depression on the numbers of residents detected and referred by care staff for further assessment.

METHOD

A cluster randomized controlled design was used to compare the referral rates for residents in seven facilities randomly allocated into one of three conditions: staff training, staff training plus a screening and referral protocol and wait-list control. Participants were 216 aged care residents (M age = 87 years), who agreed to a 12-month audit of their facility file.

RESULTS

Staff training on its own did not increase the rate of referrals for depression; however, staff training plus the screening protocol and referral guidelines did lead to a significant increase in the number of residents who were referred to a medical practitioner for further assessment. However, this increase in care staff referrals did not result in substantial changes in the treatment prescribed for residents.

CONCLUSION

Staff training in depression, supplemented with a protocol for routine screening and guidelines on referring residents, can improve pathways to care. However, strategies to overcome barriers to appropriate subsequent treatment of depression are required for staff-focused initiatives to translate into better outcomes for depressed older adults. Methodological limitations of this study are discussed.
