AbstractRotavirus vaccination reduces the incidence and severity of acute gastroenteritis due to rotavirus infection. However, because of a lack of understanding and private payment for the rotavirus vaccine, the rotavirus vaccination rate is still low in some countries. We intended to assess the impact of shared decision-making (SDM) with the assistance of patient decision aids (PDAs) on the rotavirus vaccination rate, and the knowledge, confidence, and congruence of value among baby's parents when decision-making. The study was a two-group, outcome assessor-blind, randomized, controlled trial. The families of 1-month-old infants for routine vaccination were enrolled; they were divided randomly into non-SDM and SDM groups. The influence of SDM on the acceptance of rotavirus vaccination was assessed when their infants were 2 months old. Outcome measures were decisional conflict, decision-making difficulties, and rotavirus vaccine knowledge, and the overall rotavirus vaccination rate. The study enrolled 180 participants. SDM, parents' education level, and rotavirus vaccination of a previous child were variables that influenced acceptance of rotavirus vaccination. The SDM group scored significantly higher for understanding the information on the oral rotavirus vaccine than the non-SDM group, which helped them to decide whether to vaccinate the baby against rotavirus. The rotavirus vaccination rate was 16.7% higher in the SDM group than the non-SDM group. SDM assisted with PDAs gives more information and helps infants' families understand what they need, reduces their decision conflict, and increases their baby's vaccination against rotavirus, which promotes public health. The clinical trial is registered at ClinicalTrials.gov (NCT03804489).Copyright © 2020 Elsevier Inc. All rights reserved.
