153 7 Improving Enhanced Recovery After Surgery (ERAS): The Effect of a Patient-Centred Mobile Application RESULTS A total of 170 participants provided informed consent and were randomized. Of these participants, respectively 72 and 68 patients were analysed in the intervention and control groups and 30 participants were lost to follow-up (figure 3). The baseline characteristics of the participants, presented in Table 2, were similar between the two groups, with a predominantly male population (54.9%), a median age of 57 years, and a majority of malignant diagnoses (60.1%). Despite randomization, diverticulitis was significantly more prevalent in the control group (p=0.044). Minimally invasive surgery was the predominant mode of surgery in both groups (91.5%), and both groups had sufficient scores on the mobile proficiency questionnaire. Baseline PROM’s are reported in Table 6. Figure 3: Treatment assignment and study flow
