Implementation of a Personalized Digital Application for Pediatric Pre-Anesthesia Evaluation and Education: An Ongoing Usability Analysis and Dynamic Improvement Scheme (Preprint)

Abstract

: Pre-anesthesia evaluation session is a basic practice preceding any surgical procedure, aimed at tailoring individualized anesthetic plan per patient, improving safety, and providing patients with educational knowledge and tools in preparation for the surgery day. In the last two decades, electronic health (eHealth) and mobile health (mHealth) settings gradually replaced part of the face-to-face encounters as the platform for pre-anesthesia communication between doctor and patient, yielding a range of benefits as demonstrated in recent publications. Yet, there is a lack of studies examining the effectiveness of surgical mHealth applications focusing on the pediatric preanesthetic setting and addressing their usability among families.

This study describes a dynamic approach for the development process of GistMD’s pre-anesthesia mHealth system, a mobile-based educational and management system designed for the pediatric setting.

The study was conducted in four departments in a 1500-beds quaternary, academic medical center in Tel Aviv, Israel. During the study period, pre-anesthesia system was sent via text message to families whose children were about to undergo surgery. The system included pre-anesthesia questionnaires, educational videos, downloadable instructions, and consent forms. Ongoing collection and examination of usability data were conducted during the implementation term including responsiveness, effectiveness, and satisfaction indicators. The information collected in each stage was used to draw conclusions regarding potential usability gaps of the system and to plan product adjustments for the following period.

In a period of 141 days of implementation, GistMD pre-anesthesia management system was sent to 769 families. Three product fit actions were applied during this term: (1) Change of text message scheduling, aimed at addressing learnability and accessibility, resulted in a significant increase of 27% in view rates and 27.4% in satisfaction rates; (2) Reduce the number of screens, aimed at increasing efficiency and operability, resulted in a significant decrease of 11.4% of cases in which the video was stopped before reaching its midpoint; (3) Patient-focused campaign in two departments aimed at addressing memorability, resulted in significant increases in eight of twelve usability indicators.

Our results indicate that mHealth product-fit decisions derived from theory-based approach and ongoing usability data analysis allow tailoring of most appropriate responses for usability gaps, as reflected in increasing use rates and satisfaction. In the case of the pre-anesthesia management system in the pediatric setting, increased usability conveyed important benefits for patients and families. This work suggests a framework and study methods that may also be applicable in other mHealth settings and domains.
