The effects of cancer clinical decision support systems on patient-reported outcomes: A systematic review

Abstract

Purpose: The implementation of high-quality decision-making support are integral to ensuring the delivery of quality cancer care and subsequently achieving positive patient outcomes. Decision Support Systems (DSS) are increasingly used, however it is not known what the effects are beyond supporting the decision-making process. We aimed to identify and synthesize the available literature regarding the effects of DSS on patient-reported outcomes both during and after cancer treatment.; Methods: A systematic review was conducted using dual processes to identify empirical literature that reported an evaluation of DSS interventions and patient-reported outcomes. We appraised study quality using the Mixed Methods Appraisal Tool (MMAT). Data were narratively synthesized.; Results: We included 15 studies, categorized as symptom assessment interventions or interactive educational interventions. Findings were mixed regarding the effectiveness of DSS interventions in improving total symptom distress and severity, whereas the majority were effective in reducing mean scores for worst and usual pain. Interventions were not effective in improving other health-related patient-reported outcomes including quality of life, global distress, depression, or self-efficacy and there were mixed effects for reducing decisional conflict. There was moderate to high patient adherence to the interventions and generally high satisfaction and acceptability, yet minimal evidence for the effect of DSS interventions in clinician adherence to intervention recommendations.; Conclusions: Including patient-reported outcomes in the evaluation of DSS is critical to understand their impact. Inconsistencies in reporting of interventions may, however, be a contributing factor to heterogeneous effects of clinical DSS regarding a broad range of patient-reported outcomes.; Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests.Natalie Bradford reports financial support was provided by National Health and Medical Research Council.
