Dementia care mapping in nursing homes: effects on caregiver attitudes, job satisfaction, and burnout. A quasi-experimental trial.

BACKGROUND: The Dementia Care Mapping (DCM) method is an internationally recognized complex intervention in dementia research and care for implementing person-centered care. The Leben-QD II trial aimed to evaluate the effectiveness of DCM with regard to caregivers. METHODS: The nine participating nursing home units were allocated to three groups: (1) DCM method experienced ≥ 1 year, (2) DCM newly introduced during this trial, and (3) regular rating of residents' quality of life (control group). Linear mixed models were fit to cluster-aggregated data after 0, 6, and 18 months, adjusting for repeated measurements and confounders. The primary outcome was the Approaches to Dementia Questionnaire (ADQ) score; the secondary outcomes were the Copenhagen Psychosocial Questionnaire (COPSOQ) and the Copenhagen Burnout Inventory (CBI). RESULTS: The analysis included 201 caregivers with 290 completed questionnaires (all three data collection time points). The ADQ showed a significant time and time*intervention effect. At baseline, the estimated least-square means for the ADQ were 71.98 (group A), 72.46 (group B), and 71.15 (group C). The non-linear follow-up of group A indicated an estimated-least square means of 69.71 (T 1) and 68.97 (T 2); for group B, 72.80 (T 1) and 72.29 (T 2); and for group C, 66.43 (T 1) and 70.62 (T 2). CONCLUSIONS: The DCM method showed a tendency toward negatively affecting the primary and secondary outcomes; this finding could be explained by the substantial deviation in adherence to the intervention protocol.

Dementia care mapping: effects on residents' quality of life and challenging behavior in German nursing homes. A quasi-experimental trial.

BACKGROUND: Person-centered care (PCC) is a widely recognized concept in dementia research and care. Dementia Care Mapping (DCM) is a method for implementing PCC. Prior studies have yielded heterogeneous results regarding the effectiveness of DCM for people with dementia (PwD). We aimed to investigate the effectiveness of DCM with regard to quality of life (QoL) and challenging behavior in PwD in nursing homes (NHs). METHODS: Leben-QD II is an 18-month, three-armed, pragmatic quasi-experimental trial. The sample of PwD was divided into three groups with three living units per group: (A) DCM applied since 2009, (B) DCM newly introduced during the study, and (C) a control intervention based on a regular and standardized QoL rating. The primary outcome was QoL measured with the Quality of Life-Alzheimer's Disease (QoL-AD) proxy, and the secondary outcomes were QoL (measured with QUALIDEM) and challenging behavior (measured with the Neuropsychiatric Inventory Nursing Home version, NPI-NH). RESULTS: There were no significant differences either between the DCM intervention groups and the control group or between the two DCM intervention groups regarding changes in the primary or secondary outcomes. At baseline, the estimated least square means of the QoL-AD proxy for groups A, B, and C were 32.54 (confidence interval, hereafter CI: 29.36-35.72), 33.62 (CI: 30.55-36.68), and 30.50 (CI: 27.47-33.52), respectively. The DCM groups A (31.32; CI: 28.15-34.48) and B (27.60; CI: 24.51-30.69) exhibited a reduction in QoL values, whereas group C exhibited an increase (32.54; CI: 29.44-35.64) after T2. CONCLUSIONS: DCM exhibited no statistically significant effect in terms of QoL and challenging behavior of PwD in NHs. To increase the likelihood of a positive effect for PwD, it is necessary to ensure successful implementation of the intervention.
