Objective This study evaluated whether a consumer codesigned leaflet about the common skin infection cellulitis would improve patient satisfaction. Methods A patient information leaflet was codesigned with consumers incorporating health literacy principles and attached to a new adult lower limb cellulitis management plan launched in three regional Victorian health services. Health service staff were educated to provide the leaflet during hospital care. Patients discharged with a diagnosis of cellulitis in an 8-month period were followed-up via telephone between 31 and 60 days after their discharge. Each patient was asked to provide feedback on the utility of the leaflet (if received) and their overall satisfaction with the information provided to them using a five-point scale (with scores of 4 or 5 considered to indicate satisfaction). Results In all, 81 of 127 (64%) patients (or carers) were contactable, consented to the study and answered the questions. Of these, 27% (n = 22) reported receiving, accepting and reading the leaflet. The proportion of patients who were satisfied with the information provided to them about cellulitis was 100% for those who received the leaflet, compared with 78% for those who did not receive the leaflet (95% confidence interval 4.8–34%; P = 0.02). Conclusion The provision of a consumer codesigned leaflet increased patient satisfaction with the information received about cellulitis. Real-world strategies to embed the delivery of such resources are required to ensure that more patients receive the benefit. What is known about the topic? There are known deficiencies in the information provided to patients about the common skin condition cellulitis. There is little published evaluation of strategies to address these knowledge deficiencies. What does this paper add? This study evaluated a simple strategy to address patient knowledge deficiencies on cellulitis. It highlights that pertinent information delivered in an accessible way can significantly increase patient satisfaction with the information provided to them. What are the implications for practitioners? These findings are a timely reminder for practitioners that even a simple intervention, such a providing a hard copy information leaflet, can improve patient satisfaction. A national repository of similar consumer codesigned materials would be valuable and could minimise existing duplication of effort in resource development across health sectors. Real-world strategies to embed the delivery of such resources is required to ensure that more patients receive the benefit.
