CONTROLLED STUDIES

Hilgeman et al. (2014) [17]

United States

To examine the impact of the Preserving Identity and Planning for Advance Care (PIPAC) intervention on coping strategies in early stages of dementia.

Two-group randomized controlled block design.

Qualitative and quantitative

Yes,

a minimal support-based intervention focused on empathic listening and supportive reflection through two phone calls (10–30 min.). When no phone was available, brief face-to-face interactions were used.

People with early-stage dementia aged 55 and older and their family members/friends.

Depression and anxiety symptoms; quality of life; meaning in life; emotional support; health-related quality of life; perceptions of uncertainty in choosing future medical care; coping strategies for managing memory problems.

PIPAC group: 10 dyads. People with dementia: Mean age 80.8 (SD: 4.5); 7 female; mean years of education 13.9 (SD 3.4). Family contacts mean age 66.2 (SD: 11.3); 6 female; mean year of education 15.8 (SD 1.8).

Minimal support group: 7 dyads and 1 person with dementia alone. People with dementia: Mean age 84.3 (SD: 8.0); 6 female; mean years of education 16.8 (SD 3.2). Family contacts mean age 68.6 (SD: 11.7); 5 female; mean year of education 16.3 (SD 1.8).

Yes,

routine memory clinic services (nurse-led review and access to services such as psychiatry, psychology, occupational therapy, social services)

Song et al. (2019) [19]

United States

To adapt an efficacious Advanced Care Planning intervention, SPIRIT (sharing patient’s illness representations to increase trust), to be suitable for people with dementia and their surrogates.

To assess whether people with dementia could meaningfully participate in the modified SPIRIT intervention and complete the outcome assessments.

Randomized controlled trial.

Qualitative

Yes,

the modified version of SPIRIT for people with dementias was tested. A remote and in-person version were compared.

People with (mild or moderate) dementia and their surrogates.

Quantitative preparedness outcomes in the person with dementia and the surrogate:

Dyad congruence in decision making, patient decisional conflict, and surrogate decision making confidence.

Feasibility of SPIRIT - 1) tracking technical difficulties during SPIRIT remote sessions, 2) scoring PWD’s articulation of end-of-life care preferences, 3) rating their level of recollection of the SPIRIT session, and 4) tracking measures and items that PWDs found difficulty to understand.

Acceptability and impact of SPIRIT - semi structured interview guide with each member of the dyad regarding their experience, perceived impact, facets that were experienced helpful or unhelpful, and suggestions for improvement.

23 people with dementia and their surrogates (11 in the remote group and 12 in the in-person group).

Remote (intervention) group:

People with dementia: Mean age 74.7 (SD: 7.9); 5 female.

Surrogates: Mean age 69.7 (SD: 9.8); 7 female.

Control (in-person) group:

People with dementia: Mean age 73.7 (SD: 7.5); 7 female.

Surrogates: Mean age 63.1 (SD: 11.8); 8 female.

Stockwell-Smith et al (2018) [16]

Australia

To evaluate the effect of EDDI (Early Diagnosis Dyadic Intervention) a targeted community-based psychosocial intervention on self-efficacy outcomes for dementia dyads (person with dementia and their family carer) living with early-stage dementia.

Cluster randomized controlled design

Quantitative and qualitative.

Yes,

control participants were provided with two information manuals.

Dyads of a person with early-stage dementia and their family carer.

Outcome measures was the self-rated self-efficacy (questionnaire). Data was collected at baseline, post-intervention (4 months’ postbaseline for the control group), and 4-month post-intervention.

Post-intervention evaluation interviews were conducted with the dyad and the interventionist.

88 people with dementia and their surrogates (45 in the intervention group and 43 in the control group).

Intervention (EDDI) group:

People with dementia: mean age 77.2 (SD 7.7); 14 female.

Carers: mean age 68.9 (SD 10.9); 37 female.

Control group:

People with dementia: mean age 78.5 (SD 6.4); 24 female.

Carers: mean age 69.0 (SD 11.6); 34 female.

UNCONTROLLED STUDIES

Orsulic-Jeras et al. (2016) [20]
