Abstract
Purpose
The experiment introduces nutritional labelling, healthier products and product placement designs to the hospital vending machines, to promote healthy lifestyles.
Design/methodology/approach
The site where this experiment happens is a major London hospital, serving over a million patients every year. In the experiment, the hospital’s snack and drink vending machines are redesigned. The impact on product sales are then analysed using robust statistical methods.
Findings
Nutritional labelling has a statistically significant impact on product sales. Less of the unhealthiest products are sold. Healthier products and product placement designs have a larger impact but with less statistical significance. They require further testing.
Research limitations/implications
Experts in service operations can use this experiment’s regression modelling methods. The methods are ideal for measuring change over time in counting data sets in complex real world environments.
Practical implications
There are suggestions for practical vending service change in this research. They are in line and add a practical example to Government policy guidance.
Social implications
People using the redesigned vending machines have more opportunity for healthy lifestyle choices.
Originality/value
The experiment provides statistical evidence in support of catering for healthier lifestyles.
