Influence of pre-admission factors on quality of life and adaptation in nursing home residents with dementia: the QOL-EHPAD study protocol

French cross-cultural adaptation and validation of the Quality of Life-Alzheimer's Disease scale in Nursing Homes (QOL-AD NH)

BACKGROUND

No specific scale to measure Quality of Life in Alzheimer's Disease in Nursing Homes (QoL-AD NH) exists in French. We aimed to translate and culturally adapt the QoL-AD NH participant scale into a French version and evaluate its psychometric properties with residents in French nursing homes (EHPAD).

METHODS

First, the QoL-AD NH was cross-culturally adapted into French according to guidelines. Secondly, a convenience group of residents with mild to moderate dementia answered the Folstein's test and the QoL-AD NH. They also answered the Dementia Quality of Life and the Geriatric Depression Scale to test convergent and divergent validity. Known-group validity was tested with a comparison group of residents without dementia. Exploratory Structural Equation Modeling (ESEM) was used after Exploratory Factor Analysis (EFA) to identify factors and measure invariance across age and mental state groups. Reliability (internal consistency, McDonald's omega and test-retest) were also measured.

RESULTS

Following successful adaptation of the QoL-AD NH, 174 residents (mean age 86.6) from 7 nursing homes with mild to moderate dementia participated in the validation study. We retained a 3-factor model of the scale after ESEM identifying: "Intra & interpersonal environment-related QoL", "Self-functioning-related QoL" and "Perceived current health-related QoL" that were invariant across age and mental state groups. The QoL-AD NH had acceptable convergent (ρ range 0.24-0.53) and divergent validity (ρ range - 0.43 to - 0.57) and good known-group validity with 33 residents without dementia (t(205) = 2.70, p = .007). For reliability, the results revealed very good and adequate internal consistency (α = 0.86 for total scale and ≥ 0.71 for subscales). All total omega values exceeded the threshold 0.70. The hierarchical omega was 0.50, supporting the multidimensionality of the scale. Hierarchical omega subscale values exceeded the minimal level 0.50 except for the third factor, although reliable, would deserve more items. Test-retest was good with ICC (3,1) = 0.76.

CONCLUSIONS

The QoL-AD NH French participant version has globally good reliability and validity for evaluating residents' quality of life. However, further studies must rework and confirm the factor structure, test sensitivity to change and responsiveness.

Impact of care pathway for nursing home residents treated for cancer: ONCO-EHPAD study

PURPOSE

Few data are known about cancer management in frail nursing home residents.

METHODS

Objective of our prospective, interventional study was to set up in the Marseille area, a care pathway for nursing homes residents with a suspected cancer. It combined cancer diagnosis procedures and comprehensive geriatric assessment (CGA), both made in our geriatric oncology outpatient unit, before oncologic advice for treatment decision. In standard care, CGA is carried out after therapeutic decision, to determine whether the planned treatment is compatible with the patient's frailties. CGA and quality of life were performed at enrolment and at 6 months. This study was registered in ClinicalTrials.gov (NCT03103659).

RESULTS

Between April 2017 and March 2020, 48 residents from 38 nursing homes were included: 24 had the care pathway (PP), and 24 the standard care (NPP). Six were excluded (no cancer). PP had more frailties than NPP. All PP and 75% of NPP had outpatient care. Curative treatment was given to 77% of NPP (including chemotherapy in 10 cases), and 25% of PP (surgery, radiotherapy, hormone therapy). A majority of PP (75%) had supportive care. At 6 months, 16 patients died (11 NPP, 5 PP). Quality of life evolution was available for 11 PP and 7NPP: it showed stability in PP and degradation in NPP.

CONCLUSION

Even if part of residents were too frail to get curative treatment, the care pathway enabled them to benefit from oncologic advice and appropriate supportive care while preserving their quality of life. Further investigations are needed to confirm these findings.

Factors influencing the deterioration from cognitive decline of normal aging to dementia among nursing home residents

BACKGROUND

A dearth of differential research exists regarding the determinants of mild cognitive impairment (MCI) and moderate cognitive impairment or dementia among nursing home residents. This study aimed to identify and examine the association between medical factors (number of comorbidities, hospitalization, disability, depression, frailty and quality of life) and moderate cognitive impairment or dementia in nursing homes residents.

METHODS

A cross-sectional design was used in this study. Convenience sampling of 182 participants was conducted in nursing homes located in the central part of Jordan. Montreal cognitive assessment (MoCA) was used to screen both MCI and moderate cognitive impairment or dementia. Bivariate analysis, including t-test and ANOVA test, and logistic and linear regression models were used to examine and identify the medical factors associated with moderate cognitive impairment or dementia compared to mild cognitive impairment.

RESULTS

Most nursing home residents had MCI (87.4%) compared to a few with moderate cognitive impairment or dementia. Age (t = - 2.773), number of comorbidities (t = - 4.045), depression (t = - 4.809), frailty (t = - 4.038), and quality of life physical (t = 3.282) and mental component summaries (t = 2.469) were significantly different between the stages of cognitive impairment. Marital status (t = - 4.050, p <  0.001), higher-income (t = 3.755, p <  0.001), recent hospitalization (t = 2.622,p = 0.01), depression (t = - 2.737, p = 0.007), and frailty (t = 2.852, p = 0.005) were significantly associated with mental ability scores among nursing home residents.

CONCLUSION

The coexistence of comorbidities and depression among nursing home residents with MCI necessitates prompt management by healthcare providers to combat depressive symptoms in order to delay the dementia trajectory among at-risk residents.
