BackgroundThe Older Persons and Informal Caregivers Survey Minimal Dataset’s (TOPICS-MDS) questionnaire which measures relevant outcomes for elderly people was successfully incorporated into over 60 research projects of the Dutch National Care for the Elderly Programme. A composite endpoint (CEP) for this instrument would be helpful to compare effectiveness of the various intervention projects. Therefore, our aim is to establish a CEP for the TOPICS-MDS questionnaire, based on the preferences of elderly persons and informal caregivers.MethodsA vignette study was conducted with 200 persons (124 elderly and 76 informal caregivers) as raters. The vignettes described eight TOPICS-MDS outcomes of older persons (morbidity, functional limitations, emotional well-being, pain experience, cognitive functioning, social functioning, self-perceived health and self-perceived quality of life) and the raters assessed the general well-being (GWB) of these vignette cases on a numeric rating scale (0–10). Mixed linear regression analyses were used to derive the preference weights of the TOPICS-MDS outcomes (dependent variable: GWB scores; fixed factors: the eight outcomes; unstandardized coefficients: preference weights).ResultsThe mixed regression model that combined the eight outcomes showed that the weights varied from 0.01 for social functioning to 0.16 for self-perceived health. A model that included “informal caregiver” showed that the interactions between this variable and each of the eight outcomes were not significant (p > 0.05).ConclusionA preference-weighted CEP for TOPICS-MDS questionnaire was established based on the preferences of older persons and informal caregivers. With this CEP optimal comparing the effectiveness of interventions in older persons can be realized.

BackgroundTo assess the effectiveness of geriatric interventions, The Older Persons and Informal Caregivers Survey – Composite Endpoint (TOPICS-CEP) has been developed based on health valuations of older persons and informal caregivers. This study explored the influence of the raters’ age on the preference weights of TOPICS-CEP’s components.MethodsA vignette study was conducted with 200 raters (mean age ± standard deviation: 72.5±11.8 years; 66.5% female). Profiles of older persons were used to obtain the preference weights for all TOPICS-CEP components: morbidity, functional limitations, emotional well-being, pain experience, cognitive functioning, social functioning, self-perceived health, and self-perceived quality of life. The raters assessed the general wellbeing of these vignettes on a 0–10 scale. Mixed linear regression analysis with interaction terms was used to explore the effects of raters’ age on the preference weights.ResultsInteraction effects between age and the TOPICS-CEP components showed that older raters gave significantly (P<0.05) more weight to functional limitations and social functioning and less to morbidities and pain experience, compared to younger raters.ConclusionResearchers examining effectiveness in elderly care need to consider the discrepancies between health valuations of younger olds and older olds when selecting or establishing outcome measures. In clinical decision making, health care professionals need to be aware of this discrepancy as well. For this reason we highly recommend shared decision making in geriatric care.

BackgroundPreference-weighted multi-faceted endpoints have the potential to facilitate comparative effectiveness research that incorporates patient preferences. The Older Persons and Informal Caregivers Survey—Composite endpoint (TOPICS-CEP) is potentially a valuable outcome measure for evaluating interventions in geriatric care as it combines multiple outcomes relevant to older persons in a single metric. The objective of this study was to validate TOPICS-CEP across different study settings (general population, primary care and hospital).MethodsData were extracted from TOPICS Minimum Dataset (MDS), a pooled public-access national database with information on older persons throughout the Netherlands. Data of 17,603 older persons were used. Meta-correlations were performed between TOPICS-CEP indexed scores, EuroQol5-D utility scores and Cantril’s ladder life satisfaction scores. Mixed linear regression analyses were performed to compare TOPICS-CEP indexed scores between known groups, e.g. persons with versus without depression.ResultsIn the complete sample and when stratified by study setting TOPICS-CEP and Cantril’s ladder were moderately correlated, whereas TOPICS-CEP and EQ-5D were highly correlated. Higher mean TOPICS-CEP scores were found in persons who were: married, lived independently and had an education at university level. Moreover, higher mean TOPICS-CEP scores were found in persons without dementia, depression, and dizziness with falls, respectively. Similar results were found when stratified by subgroup.ConclusionThis study supports that TOPICS-CEP is a robust measure which can potentially be used in broad settings to identify the effect of intervention or of prevention in elderly care.

Background: The Older Persons and Informal Caregivers Minimum Data Set (TOPICS-MDS) is a standardized data set that was developed to evaluate the quality of multidimensional geriatric care. There is an inherent need to reduce the number of TOPICS-MDS survey items to core outcomes to allow it to be more easily applied as a patient-reported outcome measure in clinical settings. Objectives: To create a TOPICSshort form (TOPICS-SF) and examine its validity. Methods: Data in the TOPICS-MDS from persons aged 65 years and older in the Netherlands were used for the following analyses. Multiple linear regression analyses were performed to select the items and to derive domain weights of TOPICS-SF. A priori hypotheses were made on the basis of psychometric properties of the full-length TOPICS-MDS preference-weighted score (TOPICS-CEP). The validity of TOPICS-SF was evaluated by 1) examining the meta-correlation of the TOPICS-SF score with TOPICS-CEP and two quality-of-life measures, that is, the Cantril Ladder score and the EuroQol five-dimensional questionnaire utility index, and 2) performing mixed multiple regression of TOPICS-SF scores across key sociodemographic characteristics. Results: TOPICS-SF scores were strongly correlated with the TOPICS-CEP (r ¼ 0.96) and had stronger correlation with the EuroQol five-dimensional questionnaire utility index compared with the Cantril Ladder (r ¼ 0.61 and 0.38, respectively). TOPICS-SF scores were higher among older persons who were married, living independently, and having higher levels of education. Conclusions: We have developed the 22-item TOPICS-SF and demonstrated its validity, supporting its use as a patient-reported outcome measure in geriatric care.

In shared decision making, the exploration of preferred personal health outcomes is important. Patient-reported outcome measures (PROMs) provide input for discussions between patients and healthcare professionals. The Older Persons and Informal Caregivers Survey Minimum DataSet (TOPICS-MDS) PROM is a multidimensional questionnaire on the physical and mental health and wellbeing of older adults. This study investigates how the TOPICS-MDS could be used in individual healthcare conversations. We explored views of older adults regarding 1) whether the health domains they want to discuss are included in the TOPICS-MDS and 2) the comprehensibility of the TOPICS-MDS for healthcare conversations with older adults. A three-round Delphi study was conducted. A total of 57 older adults participated in the study, the mean (SD) age was 71.5 (8.5) years, and 78.9% of the participants were female. The participants were divided into four panels based on educational level and cultural background. We used online questionnaires and focus groups. Consensus was pre-defined to be the point when ≥75% of the participants agreed that a domain was important or very important (scored on a 5-point Likert scale). The inter-expert agreement was computed for Round 1 and 3 with Kendall’s W. Round 2 was a focus-group. Qualitative data were analyzed by content analysis. Older adults considered 'functional limitations', 'emotional wellbeing', 'social functioning' and 'quality of life' to be important domains of the TOPICS-MDS to discuss in healthcare conversations. The participants added 'coping with stress', 'dealing with health conditions and the effects on life' as extra domains for healthcare conversations. Challenges regarding the comprehensibility of the TOPICS-MDS included difficult words and lengthy or sensitive questions. Questions that included multiple topics were difficult to understand. The TOPICS-MDS covers the domains of life that older adults value as important to discuss with healthcare professionals, and two additional domains were identified. For older adults with a low level of education or a culturally diverse background, the TOPICS-MDS needs to be adjusted for comprehensibility.
