Background In 2010, the human papillomavirus (HPV) vaccination was introduced in the Dutch National Immunization Program for 12-year-old girls, aiming to reduce the incidence of cervical cancer in women. HPV vaccination uptake turned out to be lower than expected: 61% versus 70%, respectively. Mothers were shown to play the most important role in the immunization decision about this vaccination. They had also expressed their need for interactive personal information about the HPV vaccination over and above the existing universal general information. To improve the effectiveness of the existing education about the HPV vaccination, we systematically developed a Web-based tailored intervention with virtual assistants providing mothers of girls to be invited with tailored feedback on their decision making about the HPV vaccination. Objective The aim of this study was to evaluate the effectiveness of the Web-based tailored intervention for promoting HPV vaccination acceptance by means of a randomized controlled trial (RCT). Methods Mothers were recruited via the Dutch vaccination register (Praeventis) (n=36,000) and three Web-based panels (n=2483). Those who gave informed consent (N=8062) were randomly assigned to the control (n=4067) or intervention condition (n=3995). HPV vaccination uptake, as registered by Praeventis once the HPV vaccination round was completed, was used as the primary outcome. Secondary outcomes were differential scores across conditions between baseline (before the provided access to the new tailored intervention) and follow-up (just before the first vaccination) regarding the mothers’ degree of informed decision making (IDM), decisional conflict, and critical determinants of HPV vaccination uptake among which are intention, attitude, risk perception, and outcome beliefs. Results Intention-to-treat analysis (N=8062) showed a significant positive effect of the intervention on IDM, decisional conflict, and nearly all determinants of HPV vaccination uptake (P<.001). No effect was found on uptake (P=.60). This may be attributed to the overall high uptake rates in both conditions. Mothers evaluated the intervention as highly positive, including the website as well as the virtual assistants that were used to deliver the tailored feedback. Conclusions This computer-tailored intervention has the potential to improve HPV vaccination acceptability and IDM and to decrease decisional conflict among mothers of invited girls. Implications for future research are discussed.

BACKGROUND In the Netherlands, human papillomavirus (HPV) vaccination uptake remains low. To improve informed decision making (IDM) and HPV vaccination acceptability, we systematically developed an interactive, web-based tailored intervention to which mothers of Dutch girls were invited to participate. OBJECTIVE The aim of this study was to provide insight into the intervention’s working mechanisms by evaluating (1) program use, (2) program acceptability, and (3) the relationship of program use with program acceptability and intervention effects (ie, dose-response relationship). METHODS Only mothers from the intervention arm of a randomized controlled trial that assessed the effectiveness of the web-based, tailored intervention were included in this study. They were invited to visit the website of the web-based intervention between baseline (January 2015, just before access to the intervention) and follow up (March 2015, prior to the first HPV vaccination). Indicators for program use were time of website use (ie, duration of intervention exposure) and completeness (ie, proportion of all available web pages visited). HPV vaccination uptake registered by Praeventis was used as the primary outcome. Secondary outcomes were IDM, decisional conflict, and social-psychological determinants of HPV vaccination uptake. RESULTS Among the 3995 invited mothers, 2509 (62.80%) logged on to the website, 2239 of whom (89.24%) visited at least one page of the intervention components. On average, mothers spent 21.39 minutes (SD 12.41) on the website and completed 50.04% (SD 26.18%) of the website components. Participants rated the website 7.64 (SD 1.39) on a 10-point scale. Program acceptability was significantly associated with completeness (β=4.36, <i>P</i>&lt;.001), but not with time of website use (β=–.07, <i>P</i>=.77). Intention-to-treat analysis (N=3995) showed a significant positive effect of completeness on all outcome measures (all <i>P</i>&lt;.003; Bonferroni-corrected α=.05/15 factors), including on HPV vaccination uptake. Time of website use had a significant positive effect on all outcomes (all <i>P</i>&lt;.003), except for uptake (<i>P</i>=.20), risk perception when not vaccinated (<i>P</i>=.14), subjective norms (<i>P</i>=.03), and habit (<i>P</i>=.01). CONCLUSIONS Program use and acceptability of the intervention were adequate. Completeness was positively associated with acceptability. Furthermore, positive effects (ie, dose-response effects) were found for completeness and time of website use on the mothers’ IDM, decisional conflict, and almost all of the social-psychological determinants of HPV vaccination acceptability. In addition, the extent to which mothers completed the intervention had a positive impact on their daughters’ vaccination uptake. This indicates that the web-based, tailored intervention fits well with the mothers’ needs, and that completeness of use is essential for improving HPV vaccination uptake, acceptability, and IDM. Program use should therefore be promoted. CLINICALTRIAL Netherlands Trial Register NTR4795; https://www.trialregister.nl/trial/4795

7033 Background: Shared decision making to confront choices with clinical equipoise, has been the privilege of those patients with access to time intensive consults with oncologists. We conducted a randomized controlled trial for breast cancer patients to use an online, self-administered, out-of-the-medical-encounter decision aid (DA) to choose between breast conserving surgery (BCS) and mastectomy. Methods: Navya Patient Preference Tool (Navya PPT) is a multilingual DA based on adaptive conjoint analysis of tradeoffs between cost, adverse effects of radiation, and breast conservation. Prior analysis established high internal reliability and external validity of the Navya PPT. Eligible cT1/2, cN0 breast cancer patients planned for surgery were block randomized, in 1:1:1 ratio, to receive the research questionnaire (RQ) to measure decisional conflict on choice of surgery (control, arm 1), Navya PPT followed by RQ (experimental, arm 2) or Navya PPT followed by RQ administered with key male family member (experimental, arm 3). Groups were stratified with respect to age, socio-economic status (SES) and educational level. The study was powered to detect a decrease in Decisional Conflict Index (DCI) by 0.25 (β-0.8, two sided α- 0.01). Results: Between June 2017 and December 2019, 247/255 patients were randomized to arm 1 (83), arm 2 (84), and arm 3 (80). Median age was 48 years (IQR 23-76), and median pT size was .5 cm (0.5-6 cm). 59% of patients were middle or lower SES and 46.2% had ≤ 12th grade education. DCI was significantly reduced in arm 2 as compared with arm 1 (1.34 vs. 1.65, Cohen’s d 0.49 (± 0.31) p<0.05) as well as in arm 3 as compared with arm 1 (1.30 vs. 1.65, Cohen’s d 0.54 (± 0.31) p<0.05). 80% (± 6%) of patients underwent surgery of choice as determined by Navya PPT. BCS rate was similar in all three arms (85.2, 88.9 and 86.5% respectively (p=0.779). Conclusions: Online, self-administered, adaptive DAs used out of the medical encounter can reduce decisional conflict and increase access to shared decision making for every patient; especially in practices with low doctor to patient ratios.
