Vaccination programs for older adults in an era of demographic change.

ABSTRACT:

Objectives

Populations are aging worldwide. This paper summarizes some of the challenges and opportunities due to the increasing burden of infectious diseases in an aging population.

Results

Older adults typically suffer elevated morbidity from infectious disease, leading to increased demand for healthcare resources and higher healthcare costs. Preventive medicine, including vaccination can potentially play a major role in preserving the health and independence of older adults. However, this potential of widespread vaccination is rarely realized. Here, we give a brief overview of the problem, discuss concrete obstacles and the potential for expanded vaccination programs to promote healthy aging.

Conclusion

The increasing healthcare burden of infectious diseases expected in aging populations could, to a large extent, be reduced by achieving higher vaccination coverage among older adults. Vaccination can thus contribute to healthy aging, alongside healthy diet and physical exercise. The available evidence indicates that dedicated programs can achieve substantial improvements in vaccination coverage among older adults, but more research is required to assess the generalizability of the results achieved by specific interventions (see Additional file 1).

Project description:IntroductionFall rates and fall-related injuries among community-dwelling older adults (≥65 years) are expected to increase rapidly, due to the aging population worldwide. Fall prevention programs (FPPs), consisting of strength and balance exercises, have been proven effective in reducing fall rates among older adults. However, these FPPs have not reached their full potential as most programs are under-enrolled. Therefore, this study aims to identify promising strategies that promote participation in FPPs among community-dwelling older adults.MethodsThis is an exploratory qualitative study. Previously, barriers and facilitators for participation in FPPs by older adults had been identified. Next, six strategies had been designed using the Intervention Mapping approach: (1) reframing; (2) informing about benefits; (3) raising awareness of risks; (4) involving social environment; (5) offering tailored intervention; (6) arranging practicalities. Strategies were validated during semi-structured interviews with community-dwelling older adults (n = 12) at risk of falling. Interviews were audio-recorded, transcribed, and analyzed following a qualitative thematic methodology, with a hybrid approach.ResultsAll strategies were considered important by at least some of the respondents. However, two strategies stood out: (1) reframing 'aging' and 'fall prevention': respondents preferred to be approached differently, taking a 'life course' perspective about falls, and avoiding confronting words; and (2) 'informing about benefits' (e.g., 'living independently for longer'); which was mentioned to improve the understanding of the relevance of participating in FPPs. Other strategies were considered important to take into account too, but opinions varied more strongly.DiscussionThis study provides insight into potential strategies to stimulate older adults to participate in FPPs. Results suggest that reframing 'aging' and 'fall prevention' may facilitate the dialogue about fall prevention, by communicating differently about the topic, for example 'staying fit and healthy', while focusing on the benefits of participating in FPPs. Gaining insight into the strategies' effectiveness and working mechanisms is an area for future research. This could lead to practical recommendations and help professionals to enhance older adults' participation in FPPs. Currently, the strategies are further developed to be applied and evaluated for effectiveness in multiple field labs in a central Dutch region (Utrecht).

Project description:Background/objectivesRecently revised vaccination recommendations for US adults, aged 65 years and older, include both 23-valent pneumococcal polysaccharide vaccine (PPSV23) and 13-valent pneumococcal conjugate vaccine (PCV13), with PCV13 now recommended for immunocompetent older people based on shared decision making. The public health impact and cost-effectiveness of this recommendation or of pneumococcal vaccine uptake improvement interventions are unclear.DesignMarkov decision analysis.Setting and participantsHypothetical 65-year-old general and black population cohorts.InterventionCurrent pneumococcal vaccination recommendations for US older people, an alternative policy omitting PCV13 in immunocompetent older people, and vaccine uptake improvement programs.ResultsThe current pneumococcal vaccination recommendation was the most effective strategy, but afforded slight public health benefits compared to an alternative (PPSV23 for all older people plus PCV13 for the immunocompromised) and cost greater than $750 000 per quality-adjusted life-year (QALY) gained in either population group with a vaccine uptake improvement program (absolute uptake increase = 12.3%; cost = $1.78/eligible patient) in place. The alternative strategy was more economically favorable, but cost greater than $100 000/QALY in either population, with or without an uptake intervention. Results were robust in sensitivity analyses; however, in black older people, the alternative strategy with an uptake program was most likely to be favored in probabilistic sensitivity analyses at a $150 000/QALY gained threshold.ConclusionCurrent pneumococcal vaccination recommendations for US older people are economically unfavorable compared to an alternative strategy omitting PCV13 in the immunocompetent. The alternative recommendation with an uptake improvement program may be economically reasonable in black population analyses and could be worth considering as a population-wide recommendation if mitigating racial disparities is a priority.
