ods to assess GvHD: their own knowledge, ‘fast facts’ sheets, scor- ing sheets, standard operating procedures, copies of original guide- line publications, or any other chosen resource.
Intervention Group: participants randomized to the “APP” group received the eGVHD App as a stand-alone GvHD assessment aid. Post-test user satisfaction and experience: post-test user satisfaction and experience was recorded in “APP” users only by “Survey 2” using a semi-structured self-report questionnaire, and two validated instruments, the “perceived usefulness” subscale of the technology acceptance model (TAM) and the Post-Study System Usability Questionnaire (PSSUQ), as described previously4 (see Online Supplementary Methods and Online Supplementary Table S4 for details).
Statistical analysis
For details of the statistical analysis see the Online Supplementary Methods.
Results
Seven out of the eleven Belgian allogeneic HCT centers participated in the study (response rate 64%). They were
essentially academic centers, covering together more than 80% of the Belgian allogenic transplantation activity (Online Supplementary Table S1).
A total of 103 individuals participated in the workshops (Figure 2). Seventy-eight professionals met the inclusion cri- teria and were randomized. One participant dropped-out due to a medical emergency in the clinic, hence data from 77 professionals were available for analysis: 37 in the “APP” Group and 40 in the “No APP” group. There was a median of 8 participants per center (range: 7-20) (Online Supplementary Table S1). Professional characteristics were similar in both groups (Table 1). The majority of partici- pants were medical doctors (75%), female (64%), and had a median age of 39 years (IQR: 20, range 22-62). Professionals reported a median experience in allogeneic HCT of six years (IQR: 11, range 0-32), and evaluated a median of one allogeneic HCT patient for GvHD per week (IQR: 5, range 0-30). The majority of healthcare profession- als reported having expertise in adult patient care. Self- reported proficiency in English was high with a median score of 7 (IQR: 1; range: 2-10) on a Likert scale of 1 (not at all fluent) to 10 (extremely fluent).
