UK hospitals have been criticized for fuelling obesity by allowing contracts with food retailers selling high fat and high-sugar products on hospital premises.
We assessed the impact for a major retailer of increasing healthy food choices at their Royal Free London NHS Foundation Trust outlet. To assess the impact on sales, profit and acceptability to customers, a multi-component intervention based on behavioural insights theory was enacted over 2 months (November-December 2014) at the Royal Free site WHSmith. Sales data on all food and drink were assessed over three time periods: (i) 2 months immediately prior to, and (ii) immediately after the intervention, and (iii) the equivalent period 10 months later. Acceptability to customers was assessed via questionnaires, and profit assessed as a proxy for retailer satisfaction.
Compared to the pre-intervention period, total sales increased immediately after the intervention, and again 10 months after the intervention. Sales of healthier options increased as a proportion of total sales following the intervention, sales of sweets and chocolates decreased, while the relative sales of other items remained similar.
We demonstrated that healthier alternatives could be provided in a hospital retail premises without negatively affecting total sales, retailer or customer satisfaction.
英国医院因允许在医院内销售高脂肪、高糖产品的食品零售商签订合同而受到批评，认为此举导致肥胖问题加剧。
我们评估了在伦敦皇家自由国民保健制度信托基金会的皇家自由医院分店，增加主要零售商的健康食品选择对其销售、利润和客户接受度的影响。为了评估对销售、利润和客户接受度的影响，我们实施了基于行为洞察理论的多组分干预措施，为期两个月（2014 年 11 月至 12 月）在皇家自由医院的 WHSmith 分店。在三个时间段评估了所有食品和饮料的销售数据：（i）干预前的两个月，（ii）干预后立即，和（iii）10 个月后的等效时间段。通过问卷调查评估客户的接受度，通过评估利润作为零售商满意度的代理指标。
与干预前相比，干预后立即和 10 个月后总销售额增加。干预后，健康选择的销售额占总销售额的比例增加，糖果和巧克力的销售额下降，而其他商品的相对销售额保持相似。
我们证明了在医院零售场所可以提供更健康的替代品，而不会对总销售额、零售商或客户满意度产生负面影响。
