OPTIMISING HEALTHCARE
T here is no panacea for the huge challenges facing the NHS. The Covid-19 pandemic, arriving after a decade of austerity, stretched services like never before. This has been exacerbated by a crisis in social care and a shortage of doctors and nurses. Curing these ills requires major policy change and investment. In the meantime, behavioural science can be an invaluable tool, encouraging medics, managers, and patients to make manageable and cost-effective changes. Here are three ways nudges can support better outcomes, drawn from our policy briefs. 1 Protecting public health The Covid-19 pandemic shone a spotlight on the challenges that policymakers face in mobilising the population to protect public health. This was particularly apparent with the reluctance of many people to have the Covid-19 vaccine. By better understanding their reasons for hesitating, we could make several recommendations to increase uptake. To boost confidence, information about the safety and effectiveness of the vaccine needed to be widely accessible, branded by the NHS, and personalised by people’s local GP where possible. The vaccine-booking system had to be user friendly, offer information about how the jab was delivered, and emphasise that it was free. It was also important to tap into individual’s desires, such as protecting those close to them, rather than themselves, and easing lockdown restrictions

We found that well-worded text messages, warning patients that each missed appointment costs £160, could prevent 400,000 missed hospital appointments each year, saving the NHS an estimated £64 million (or more if the NHS had mobile numbers for more than 20 per cent of patients). Text message reminders can also increase the number of women who attend cervical screening. NHS leaders can also use behavioural science to encourage healthcare practitioners to implement guidance on prescribing antibiotics or sedatives and making referrals. Targeting practitioners with personal letters is a low-cost intervention. Our findings suggest that it can significantly enhance decision-making. Again, framing is key. Letters that highlighted characteristics that the sender and the recipient shared, appealed to social norms, and supported a positive self-image were more effective. So were those providing clear instructions for the recipient and explaining the consequences for their patients.
understanding individual motives and barriers to immunisation can be applied to other health protection programmes, such as the annual flu vaccination programme. 2 Encouraging healthy behaviour We all know that obesity, sedentary lifestyle, and excess alcohol consumption are key contributors to ill health and lost years of life. But many of us struggle to convert that into a healthy lifestyle. This is fertile ground for carefully constructed nudges to deliver better outcomes and significant savings for the NHS and society more generally. Take alcohol, for example. We sent 101 students, all of whom drank excessively, four different text messages over four weeks and found the framing had a significant affect on the impact. When their drinking was compared to the recommended limits, just 5 per cent requested links to alcohol education websites. This rose to 45 per cent when it was compared to what others drank. Messages about healthy diet could deliver similar benefits. Losing weight through diet and exercise is only half the battle. Most people regain half of what they have lost within a year and 80 per cent return to – or exceed – their pre-diet size. But teenagers who were sent texts encouraging them to commit to healthy behaviours, such as eating a bowl of cereal each morning or fruit for dessert, and checking on their progress, were more successful at keeping the weight off. Even something as simple as changing the order that items appear on a menu can help. Our research with McDonald’s showed that moving Coke Zero to the top
