Summary
A computer-based decision aid (DA) for prenatal screening was found usable and useful by pregnant women, clinicians, and policymakers. Future implementation will incorporate user feedback for enhanced engagement and clinical practice integration.
Area of Science:
- * Health Informatics
- * Reproductive Health
- * Shared Decision-Making
Background:
- * Mobile health tools can enhance shared decision-making in healthcare.
- * A computer-based decision aid (DA) was developed to support informed decisions regarding prenatal screening for trisomy among pregnant women and their partners.
Purpose of the Study:
- * To assess the usability and usefulness of the computer-based DA.
- * To evaluate the DA's impact on pregnant women's decision-making confidence.
- * To gather feedback from pregnant women, clinicians, and policymakers for future improvements.
Main Methods:
- * A mixed-methods sequential explanatory study design.
- * Convenience sampling of 45 pregnant women, 14 clinicians, and 8 policymakers.
- * Participants navigated the DA, followed by quantitative surveys and qualitative interviews exploring usability, usefulness, quality, acceptability, and satisfaction.
Main Results:
- * High usefulness (80/100) and self-efficacy (88/100) scores reported by pregnant women.
- * Positive usability scores across all participant groups (pregnant women: 84/100, clinicians: 77/100, policymakers: 79/100).
- * Participants found the information balanced and sufficient, with suggestions for increased engagement and integration into clinical guidelines.
Conclusions:
- * The computer-based DA is perceived as usable and useful by pregnant women, clinicians, and policymakers.
- * User-suggested improvements for engagement will be incorporated.
- * Implementation of the DA into clinical practice is the recommended next step.
