Reliability and validity of the Spanish version of the IDEAL Schedule for assessing care needs in dementia: Cross-sectional, multicenter study

What is new within staging of care for people with dementia? The IDEAL schedule and other recent work

PURPOSE OF REVIEW

This review provides an overview of recent progress within work centred around the 'International schedule for the integrated assessment and staging of care for dementia' (IDEAL schedule), and places it within the context of recent work around other staging models for dementia.

RECENT FINDINGS

The IDEAL schedule assesses the severity of dementia across seven dimensions. A 'Menu of care options' of recommended priorities for interventions accompanies the schedule. A user manual for the schedule has just been published. Other staging models for dementia include those based on biomarkers, such as in the recently published research framework for Alzheimer's disease by the National Institute on Aging and Alzheimer's Association (NIA-AA), or those based on specific aspects of dementia, principally cognitive impairment.

SUMMARY

The IDEAL schedule is a global staging model to guide the organization of dementia care. The schedule covers a range of domains that extend beyond cognitive functioning and include care needs; it is applicable to all types and stages of dementia; and can be used by any healthcare professional, both within clinical practice and research. The schedule is not in opposition to, or is even complementary to, other staging models for dementia.

Reliability and validity of the international dementia alliance schedule for the assessment and staging of care in China

BACKGROUND

Clinical and social services both are important for dementia care. The International Dementia Alliance (IDEAL) Schedule for the Assessment and Staging of Care was developed to guide clinical and social care for dementia. Our study aimed to assess the validity and reliability of the IDEAL schedule in China.

METHODS

Two hundred eighty-two dementia patients and their caregivers were recruited from 15 hospitals in China. Each patient-caregiver dyad was assessed with the IDEAL schedule by a rater and an observer simultaneously. The Clinical Dementia Rating (CDR), Mini-Mental Status Examination (MMSE), and Caregiver Burden Inventory (CBI) were assessed for criterion validity. IDEAL repeated assessment was conducted 7-10 days after the initial interview for 62 dyads.

RESULTS

Two hundred seventy-seven patient-caregiver dyads completed the IDEAL assessment. Inter-rater reliability for the total score of the IDEAL schedule was 0.93 (95%CI = 0.92-0.95). The inter-class coefficient for the total score of IDEAL was 0.95 for the interviewers and 0.93 for the silent raters. The IDEAL total score correlated with the global CDR score (ρ = 0.72, p < 0.001), the CDR-sum of box (CDR-SOB, ρ = 0.74, p < 0.001), the total score of MMSE (ρ = -0.65, p < 0.001) and CBI (ρ = 0.70, p < 0.001). All item scores of the IDEAL schedule were associated with the CDR-SOB (ρ = 0.17 ~ 0.79, all p < 0.05).

CONCLUSION

The IDEAL schedule is a valid and reliable tool for the staging of care for dementia in the Chinese population.
