What and how can we learn from complex global problems for antimicrobial resistance policy? A comparative study combining historical and foresight approaches.

Objectives: To (i) develop a methodology for using historical and comparative perspectives to inform policy and (ii) provide evidence for antimicrobial-resistance (AMR) policymaking by drawing on lessons from climate change and tobacco control.

Methods: Using a qualitative design, we systematically examined two other complex, large-scale policy issues-climate change and tobacco control-to identify what relevance to AMR can be learned from how these issues have evolved over time. During 2018-2020, we employed a five-stage approach to conducting an exploratory study involving a review of secondary historical analysis, identification of drivers of change, prioritisation of the identified drivers, scenario generation and elicitation of possible policy responses.

The effectiveness of community-based social innovations for healthy ageing in middle- and high-income countries: a systematic review.

Objectives: Community-based social innovations (CBSIs) are one type of intervention that may help to address the complex needs of ageing populations globally. The aim of this research was to assess evidence for the effectiveness and cost-effectiveness of CBSIs involving in such contexts.

Methods: We conducted a systematic review of CBSIs for healthy ageing in middle- and high-income countries, including any CBSI that aimed to empower people aged 50 and over by motivating them to take initiative for their own health and wellbeing.
