Area of Science:

  • Digital health interventions
  • Healthcare technology usability
  • Sexual assault care protocols

Background:

  • Mobile applications offer potential for improving healthcare delivery.
  • Usability and acceptability are critical factors for the adoption of new health technologies by healthcare professionals.
  • The sexual assault care algorithm (SACA) is a novel mobile application designed to aid in evidence-based practice.

Purpose of the Study:

  • To conduct a preliminary evaluation of the usability and acceptability of the sexual assault care algorithm (SACA) mobile application.
  • To explore user perceptions and identify areas for improvement in the SACA application.

Main Methods:

  • An explanatory sequential mixed methods design was employed, starting with quantitative surveys followed by qualitative interviews and observations.
  • A small convenience sample of four participants was recruited for one-on-one testing.
  • Quantitative data were collected using the Post-Study System Usability Questionnaire (PSSUQ) and Acceptability e-Scale, while qualitative data were gathered through interviews, observation, and documentation.

Main Results:

  • Quantitative data indicated high usability (mean score 5.05 ± 1.83) and acceptability (mean score 3.81 ± 1.22) of the SACA application.
  • Qualitative feedback revealed that participants found SACA easy to use and beneficial, with most willing to recommend it.
  • Suggested improvements included adding features for elapsed time calculation post-assault, clarifying button functions, and providing user training.

Conclusions:

  • Mixed methods research designs are valuable for assessing the usability and acceptability of health technologies.
  • Nurses are more inclined to adopt new technologies that are user-friendly, useful, and efficient in accessing guideline evidence.
  • Tailored training programs should be developed considering the specific characteristics of end-users to facilitate technology adoption.
