Social connectedness in older people: who is responsible?

Social connectedness and self-perceived health of older adults in New Zealand

The objective of this research was to explore social connectedness and associations with self-perceived health amongst older adults in New Zealand at a population level. The data for this analysis were derived from the 2016 Health and Lifestyle Survey, a nationally representative survey administered via face-to-face interviews. The findings from this analysis of 1,374 respondents, all of whom were over the age of 55 years, highlight that being female, belonging to older age groups (above 70 years), being employed full-time or part-time, connecting online with known people, considering cultural connections to be important and not feeling isolated from others are significantly and positively associated with positive self-perceived health. The findings underscore the resilience potential of older adults and importance of social connectedness for positive health and well-being. In addition, the findings reveal target areas that would benefit by intervention and support by health professionals and policy makers.

Lifestyle Matters Randomized Controlled Trial of a Preventive Health Intervention for Older People: Qualitative Sub Study with Participants and Intervention Facilitators

OBJECTIVE

This qualitative study embedded within a randomized controlled trial was conducted to explore the acceptability, experiences of, and short-term impact of a preventive health intervention (Lifestyle Matters) from the perspectives of those who took part, and to uncover any evidence for the theorised mechanisms of action (improved participation and self efficacy) underpinning the intervention. It was also conducted to help explain the quantitative trial results.

METHODS

A purposive sample of 13 trial participants who had been randomized to receive the Lifestyle Matters intervention (approximately 10%) were individually qualitatively interviewed immediately following their involvement. All four intervention facilitators were also individually interviewed.

RESULTS

Evidence of the hypothesized behavioural changes could be identified within the interview data, demonstrating the potential of this intervention. However, lack of adherence to the overall intervention eroded receipt of benefit. This finding complements the quantitative trial results which found that the study had failed to recruit those who considered themselves to be at risk of age-related decline.

CONCLUSION

This form of preventive health intervention requires proactive identification of those who recognise the need to make lifestyle changes. This is difficult if reactive health and social care systems are the main referral routes. The methodological approaches taken towards the study of complex interventions requires reconsideration if potential benefits are to be accurately assessed.

Access to health care for older people with intellectual disability: a modelling study to explore the cost-effectiveness of health checks

Background

Whilst people with intellectual disability grow older, evidence has emerged internationally about the largely unmet health needs of this specific ageing population. Health checks have been implemented in some countries to address those health inequalities. Evaluations have focused on measuring process outcomes due to challenges measuring quality of life outcomes. In addition, the cost-effectiveness is currently unknown. As part of a national guideline for this population we sought to explore the likely cost-effectiveness of annual health checks in England.

Methods

Decision-analytical Markov modelling was used to estimate the cost-effectiveness of a strategy, in which health checks were provided for older people with intellectual disability, when compared with standard care. The approach we took was explorative. Individual models were developed for a selected range of health conditions, which had an expected high economic impact and for which sufficient evidence was available for the modelling. In each of the models, hypothetical cohorts were followed from 40 yrs. of age until death. The outcome measure was cost per quality-adjusted life-year (QALY) gained. Incremental cost-effectiveness ratios (ICER) were calculated. Costs were assessed from a health provider perspective and expressed in 2016 GBP. Costs and QALYs were discounted at 3.5%. We carried out probabilistic sensitivity analysis. Data from published studies as well as expert opinion informed parameters.

Results

Health checks led to a mean QALY gain of 0.074 (95% CI 0.072 to 0.119); and mean incremental costs of £4787 (CI 95% 4773 to 5017). For a threshold of £30,000 per QALY, health checks were not cost-effective (mean ICER £85,632; 95% CI 82,762 to 131,944). Costs of intervention needed to reduce from £258 to under £100 per year in order for health checks to be cost-effective.

Conclusion

Whilst findings need to be considered with caution as the model was exploratory in that it was based on assumptions to overcome evidence gaps, they suggest that the way health systems deliver care for vulnerable populations might need to be re-examined. The work was carried out as part of a national guideline and informed recommendations about system changes to achieve more equal health care provisions.
