Optimal MoCA cutoffs for detecting biologically-defined patients with MCI and early dementia

OBJECTIVE

In this phase II psychometric study on the Montreal cognitive assessment (MoCA), we tested the clinicometric properties of Italian norms for patients with mild cognitive impairment (PwMCI) and early dementia (PwD) and provided optimal cutoffs for diagnostic purposes.

METHODS

Retrospective data collection was performed for consecutive patients with clinically and biologically defined MCI and early dementia. Forty-five patients (24 PwMCI and 21 PwD) and 25 healthy controls were included. Raw MoCA scores were adjusted according to the conventional 1-point correction (Nasreddine) and Italian norms (Conti, Santangelo, Aiello). The diagnostic properties of the original cutoff (< 26) and normative cutoffs, namely, the upper limits (uLs) of equivalent scores (ES) 1, 2, and 3, were evaluated. ROC curve analysis was performed to obtain optimal cutoffs.

RESULTS

The original cutoff demonstrated high sensitivity (0.93 [95% CI 0.84-0.98]) but low specificity (0.44 [0.32-0.56]) in discriminating between patients and controls. Nominal normative cutoffs (ES0 uLs) showed excellent specificity (SP range = 0.96-1.00 [0.88-1.00]) but poor sensitivity (SE range = 0.09-0.24 [0.04-0.36]). The optimal cutoff for Nasreddine's method was 23.50 (SE = 0.82 [0.71-0.90]; SP = 0.72 [0.60-0.82]). Optimal cutoffs were 20.97, 22.85, and 22.29 (SE range = 0.69-0.73 [0.57-0.83], SP range = 0.88-0.92 [0.77-0.97]) for Conti's, Santangelo's, and Aiello's methods, respectively.

CONCLUSION

Using the 1-point correction, combined with a cutoff of 23.50, might be useful in ambulatory settings with a large turnout. Our optimal cutoffs can offset the poor sensitivity of Italian cutoffs.

Effects of the tailored activity program (TAP) on dementia-related symptoms, health events and caregiver wellbeing: a randomized controlled trial

Background

People living with dementia (PLWD) and caregivers are adversely impacted by lack of meaningful activity leading to worse symptoms and impaired quality-of-life. There is a critical need to develop effective and well-tolerated treatments that mitigate clinical symptoms, engage PLWD and support caregiver wellbeing. We tested whether, compared to attention control, the Tailored Activity Program (TAP) reduced clinical symptoms and health-related events, and improved caregiver wellbeing, and if TAP activities were well-tolerated.

Methods

We conducted a single-blind randomized controlled trial among 250 dyads recruited from Baltimore-Washington DC (2012–2016) with a dementia diagnosis and clinically significant agitation/aggression. Dyads were randomized to TAP (n = 124) or attention control (n = 126), and interviewed at baseline, 3 (endpoint) and 6-months (follow-up) by interviewers masked to group allocation. TAP assessed PLWD abilities/interests, instructed caregivers in using prescribed activities, and provided dementia education and stress reduction techniques. Attention controls received disease education and home safety tips. Both groups had up to 8 home visits over 3-months. The primary outcome was frequency by severity scores for agitation/aggression subscales of Neuropsychiatric Inventory-Clinician using caregiver ratings. Secondary outcomes included number of instrumental (IADL) and activities of daily living (ADL) needing assistance, caregiver wellbeing, and confidence using activities. Health-related events (PLWD death, hospitalizations, caregiver hospitalization, depression) and perceived study benefits were captured over 6 months. PLWD tolerability of prescribed activities was examined.

Results

Of 250 dyads, most caregivers were female (81.2 %, n = 203), non-spouses (54.4 %, n = 136), white (59.2 %, n = 145) or African American (36.7 %, n = 90) with mean age = 65.4 (SD = 12.6). PLWD were mostly female (63.2 %, n = 158) with mean age = 81.4 (SD = 7.9), and mean MMSE = 14.3 (SD = 7.8). At 3-months, compared to controls, TAP conferred no benefit to agitation/aggression (p = 0.43, d = 0.11), but resulted in less IADL (p = 0.02, d=-0.33), and ADL (p = 0.04, d=-0.30) assistance, improved caregiver wellbeing (p = 0.01, d = 0.39), and confidence using activities (p = 0.02, d = 0.32). By 6-months, 15 PLWD in TAP had ≥ 1 health-related event versus 28 PLWD in control, demonstrating 48.8 % improvement in TAP (p = 0.03). TAP caregivers were more likely to perceive study benefits. Prescribed activities were well-tolerated.

Conclusions

Although TAP did not benefit agitation/aggression, it impacted important outcomes that matter to families warranting its use in dementia care.

A qualitative exploration of family carer's understandings of people with dementia's expectations for the future

BACKGROUND

There is little evidence that outlines how family carers understand the person with dementia's perspective, values and anticipated future needs. Whilst people with dementia should be consulted about their own quality of life and care values, carers - otherwise known as care partners - require such understandings to ensure that the support the person receives into the future upholds their quality of life and is consistent with what they desire.

AIM

This research aimed to explore and describe family carers' experience of supporting the person with dementia to maintain their quality of life by understanding how carers developed an awareness and understanding of the person with dementia's expectations for the future and what they believed was important for the person to whom they provided care.

METHOD

Using an application of the grounded theory method, data were collected from 21 carers during semi structured interviews and analysed using constant comparative analysis.

FINDINGS

Four categories emerged from the data: Knowing the person, Process of decision making, Maintaining normalcy and quality of life and Out of their control.

DISCUSSION

This study provides insights into how carers developed awareness of the expectations of people with dementia. Findings also illuminate carers' perspectives of the changing nature of decision making during the dementia trajectory.

CONCLUSION

Understanding the perspective of the person living with dementia is essential to facilitate advocacy and support that is 'person centred' now and into the future. Assisting carers to incorporate this perspective into caring has the potential to be better facilitated by health professionals and merits further investigation.

Sorting Through the Spheres of Influence: Using Modified Pile Sorting to Describe Who Influences Dairy Farmers' Decision-Making About Safety

OBJECTIVES

The primary goal of this study was to describe the mutually perceived influence of bankers and insurers on their agricultural clients' decision-making regarding health and safety.

METHODS

Semistructured interviews were conducted with 10 dairy farmers, 11 agricultural bankers, and 10 agricultural insurers from central Wisconsin. Three of the interview questions involved pile sorting. Pile sorting included 5-point Likert-like scales to help participants sort through 32 index cards. Each card represented an individual or group that was thought to possibly affect farmers' decision-making, both generally and about health and safety. Results (photographs of piles of cards quantified into spread sheets, fieldnotes, and interview transcripts) were analyzed with SAS and NVivo.

RESULTS

All three groups expressed moderate-to-strong positive opinions about involving agricultural bankers (x2(2) = 2.8155, p = 0.2695), although bankers qualitatively expressed apprehension due to regulations on the industry. Insurance agents received more positive support, particularly from bankers but also from dairy farmers themselves, and expressed more confidence in being involved in designing and implementing a farm safety program.

CONCLUSION

Agricultural bankers and insurers can influence individual farmer's decision-making about health and safety. Both are believed to be good purveyors of safety programs and knowledge, especially when leveraging financial incentives. Insurance agents are thought to be more critical in the design of safety programs. Insurers and bankers being financially tied to safety programs may prove both positive and negative, as farmers may be skeptical about the intention of the incentives, making messaging critical.
