Introduction: The ADAPT-CP to guide screening, assessment and management of anxiety and depression in adult cancer patients is based on evidence review and refined through comprehensive stakeholder review and a Delphi consensus process1,2. The ADAPT-CP follows a stepped care model incorporating iterative screening at recommended intervals, with triage to one of five steps, each with a recommended management plan for those with minimal or mild levels of anxiety and/or depression, to specialist care for those with severe anxiety and/or depression), with review and change in step where necessary.
Aims: The ADAPT Cluster RCT3 evaluated the level of implementation support required (core versus enhanced) to achieve adherence to the ADAPT CP over a 12-month period.
Methods: We developed resources and implementation strategies guided by the Promoting Action Research in Health Services (PARiHS) framework4 . We specified adherence as the percentage of all CP components (such as screening, triage, referral and re-screening) appropriate to the patient’s level of anxiety and depression to provide a site-level adherence score of 0-100. To provide a more clinically relevant measure of adherence, we further defined a categorical outcome (adherent: ≥70% of patients experienced ≥70% of key ADAPT-CP components (e.g. screening, triage, referral and re-screening); or non-adherent: <70% of patients experienced ≥70% of key ADAPT-CP components, based on accepted implementation targets.
Results: While adherence did not differ significantly between implementation arms, there was a trend toward differences between implementations arms with greater adherence to the clinical pathway for patients scoring high on clinical levels of distress in enhanced compared to core services.
Conclusions: The findings from this study confirm cancer services require additional support when implementing practice change related to more complex clinical decisions such as management of clinical anxiety and/or depression.
