Prevention is better than cure-but how to value prevention and incentivise investment?The health of the population is inextricably linked to wider economic prosperity, and COVID-19 has brought this into sharp relief (1). With deaths due to COVID-19 reaching 7 million worldwide (2), there has never been a more pivotal time to call for greater protection against future health threats. However, one of the greatest challenges is recognizing and quantifying the full value of prevention and preparedness to patients, health systems and society. Any such valuation must be comprehensively estimated to include not only the adverse consequences avoided, but also the wider benefits of effective interventions. This will align incentives to invest in patient and population health.The COVID-19 pandemic has starkly revealed how interventions that prevent illness and maintain good health, such as vaccines, antimicrobials and antivirals, provide value beyond the healthcare system alone. Not only do they alleviate illness, they also mitigate disease transmission, protecting the wider population and enabling education, work, caring and social interactions to continue. Prevention of non-communicable diseases such as heart disease and diabetes also confer similar types of value. However, traditional approaches to assessing the effectiveness of such interventions rarely capture value added beyond the healthcare setting. Something needs to change.
Realigning incentives to promote investment in population health prioritiesBy viewing through a lens of health being an asset rather than illness being a cost, the healthcare system could promote health in communities, rather than paying for treatment of ill health. Unfortunately, neither good health nor the resilience across health systems that this would support are commonly valued or incentivised (3).There are signs of progress. NICE is exploring wider definitions of value (4, 5), and its latest guidance on antimicrobial resistance (AMR) is designed to reward innovation and delink payment from quantity sold (5, 6), to support appropriate use of the antimicrobials. This echoes recent research that found therapeutic benefit was most commonly regarded as a measure of innovation (7). Secondly, the societal impacts of vaccines (8) and antivirals
