Achieving universal health coverage is the most important means to advance health and wellbeing during the next decade. Too many countries—and not only in low-income or middle-income settings—do not have a health system that provides “access to quality essential health-care services and access to safe, effective, quality and affordable essential medicines and vaccines for all”, as described in Sustainable Development Goal 3.8. Even many high-income countries, such as the USA and the UK, see important inequalities in income, life expectancy, and health outcomes, and the prevailing political and economic landscapes are not encouraging for a reversal of this trend in the foreseeable future. At the same time, changing demographics in many countries mean that the share of the population with two or more chronic conditions will increase. As a result, the resilience and sustainability of health systems will be put under even more pressure. In a recent report by the Organisation for Economic Co-operation and Development, it is estimated that the proportion of the population in European Union countries aged 65 years or older will increase from 20% in 2015 to 30% by 2060. The same report states that in 2013, more than 1·2 million people in European Union countries died from avoidable illnesses and injuries— people who would not have died had there been more effective public health and prevention policies in place, or more timely and effective health care. Yet all countries are struggling with spiralling costs of health and social care, with the prospect of rationing and restricting services—a strategy that would increase inequality and injustice still further. Failure to provide treatment and preventive care at all remains the unacceptable reality in many low-income and middle-income countries for most of their populations. Clearly, something has to change in our thinking about the provision of health and health care to achieve health and wellbeing for all. In a Series of papers and Comments in The Lancet, Vikas Saini and colleagues provide a framework for such a change of thinking. The Right Care Series examines the areas and extent of overuse and underuse of health and medical services around the world. It defines overuse as “the provision of medical services that are more likely to cause harm than good”, and underuse as “the failure to use effective and affordable medical interventions”. The Series authors argue that both overuse and underuse happen side-by-side in different countries, within countries, among populations, within institutions, and even for a single person. This situation offers an enormous (and currently poorly recognised) opportunity to tackle underuse and overuse together to achieve the right care for health and wellbeing. What is right care? In its simplest definition it is care that weighs up benefits and harms, is patient-centred (taking individual circumstances, values, and wishes into account), and is informed by evidence, including cost-effectiveness. The Series authors acknowledge that most medical services fall into a grey zone where the benefit and harm ratio for a given individual is unknown. However, an important start is to think about, and aim to influence, the drivers of poor, unnecessary, and harmful care. The authors argue that these drivers fall into three important categories: money, finance, and organisations; knowledge, beliefs, assumptions, bias, and uncertainty; and power and human relationships. To begin to address each of these levels, the roles of all actors have to be examined closely: patients, community leaders, and civil society; health-care providers and health service organisations; national policy makers and health technology assessment institutions; and global health leaders and professional societies. The best example, where progress is slowly being made, is perhaps that of reduced antibiotic prescribing to combat antibiotic resistance.
