The impact of a patient decision aid on treatment choices after anterior cruciate ligament injuries

Purpose The present study aimed to investigate whether exposure to a patient decision aid (PDA) had an impact on the proportion of patients selecting non-surgical or surgical treatments after anterior cruciate ligament (ACL) injuries and whether exposure to a PDA affected the proportion of patients switching from non-surgical to surgical treatment within the first year. Methods In a consecutive case series, proportions of surgery and non-surgery were compared before and after patients’ exposure to a PDA. Data were collected from the health records of patients with ACL injuries who presented to the Clinic of Sports Traumatology. To identify proportional differences between the two groups, t-tests and proportion tests were used. Results In total, 1,053 patients with ACL injuries were included: 563 patients with no exposure to the PDA (January 2015 to January 2017) and 490 patients with exposure to the PDA (January 2017 to January 2019). Before implementing the PDA, 27% of the patients selected non-surgical treatment. After implementing the PDA, 30% choose non-surgical treatment ( p > 0.05). Before implementing the PDA, 21% of patients who initially chose non-surgical treatment had surgery within the first year. After implementation of the PDA, this number fell to 16%, but the difference was not statistically significant ( p > 0,05). Conclusion Exposure to the PDA did not significantly alter the proportion of ACL injury patients selecting non-surgical or surgical treatments or the proportion of patients switching to surgery within the first year.
