Evaluation of a Serious Video Game to Facilitate Conversations About Human Papillomavirus Vaccination for Preteens: Pilot Randomized Controlled Trial.

ABSTRACT:

Background

In the United States, the most common sexually transmitted infection, human papillomavirus (HPV), causes genital warts and is associated with an estimated 33,700 newly diagnosed cancer cases annually. HPV vaccination, especially for preteens aged 11 to 12 years, is effective in preventing the acquisition of HPV and HPV-associated cancers. However, as of 2018, completion of the 2- or 3-dose HPV vaccination series increased only from 48.6% to 51.1% in teens aged 13 to 17 years, and this increase was observed only in boys. By comparison, 88.7% of teens had more than one dose of the recommended vaccine against tetanus, diphtheria, and acellular pertussis (Tdap), and 85.1% of teens had more than one dose of meningococcal vaccine. Immunizations for Tdap, meningococcal disease, and HPV can occur at the same clinical visit but often do not.

Objective

Vaccination against HPV is recommended for routine use in those aged 11 to 12 years in the United States, yet it is underutilized. We aimed to develop an educational video game to engage preteens in the decision to vaccinate.

Methods

Land of Secret Gardens is a metaphor for protecting seedlings (body) with a potion (vaccine). We screened 131 dyads of parents and preteens from 18 primary practices in North Carolina who had not initiated HPV vaccination. We measured vaccination intentions, story immersion, and game play and documented HPV vaccination rates. A total of 55 dyads were enrolled, and we randomly assigned 28 (21 completed) to play the game and 27 (26 completed) to the comparison group.

Results

In total, 18 preteens reported playing the game. The vaccination self-efficacy score was higher in the comparison group than the intervention group (1.65 vs 1.45; P=.05). The overall mean decisional balance score trended toward greater support of vaccination, although differences between the groups were not significant.. Vaccine initiation and completion rates were higher in the intervention group (22% vs 15%; P=.31) than in the comparison group (9% vs 2%; P=.10), although the difference was not significant.

Conclusions

Video games help preteens in the decision to pursue HPV vaccination. A serious video game on HPV vaccination is acceptable to parents and preteens and can be played as intended. Gamification is effective in increasing preteen interest in HPV vaccination, as game features support decision making for HPV vaccination.

Project description:BackgroundAdvances in emergency and critical care have improved outcomes, but gaps in communication and decision-making persist, especially in the emergency department (ED), prompting the development of a checklist to aid in serious illness conversations (SIC) in China.MethodsThis was a single-centre prospective interventional study on the quality improvement of SIC for life-sustaining treatment (LST). The study recruited patients consecutively for both its observational baseline and interventional stages until its conclusion. Eligible participants were adults over 18 years old admitted to the Emergency Intensive Care Unit (EICU) of a tertiary teaching hospital, possessing full decisional capacity or having a legal proxy. Exclusions were made for pregnant women, patients deceased upon arrival, those who refused participation, and individuals with incomplete data for analysis. First, a two-round Delphi process was organized to identify major elements and generate a standard process through a checklist. Subsequently, the efficacy of SIC in adult patients admitted to the EICU was compared using the Decisional Conflict Scale (DCS) score before (baseline group) and after (intervention group) implementing the checklist.ResultsThe study participants presented with the most common comorbidities, such as diabetes, myocardial infarction, cerebrovascular disease, moderate-to-severe renal disease, congestive heart failure, and chronic pulmonary disease. The median Charlson Index did not differ between the baseline and intervention cohorts. The median length of hospital stay was 11.0 days, and 82.9% of patients survived until hospital discharge. The total DCS score was lower in the intervention group than in the baseline group. Three subscales, including the informed, values clarity, and support subscales, demonstrated significant differences between the intervention and baseline groups. Fewer intervention group patients agreed with and changed their minds about cardiopulmonary resuscitation (CPR) compared to the baseline group.ConclusionThe use of a SIC checklist in the EICU reduced the DCS score by increasing medical information disclosure, patient value awareness, and decision-making support.

Project description:BACKGROUND:The design and use of serious video games for children have increased in recent years. To maximize the effects of these games, it is essential to understand the children's experiences through playing. Previous studies identified that enjoyment and user experience satisfaction of the players are principal factors that can influence the success of serious video games and the learning of their players. However, research about the relationship between enjoyment and user experience satisfaction with learning in children 8 to 10 years old is sparse. OBJECTIVE:We examined the relationship of enjoyment and user experience satisfaction with the learning of children aged 8 to 10 years while playing a serious video game for health, FoodRateMaster. This serious video game teaches children about the characteristics of healthy and unhealthy foods and how to identify them in their environment. METHODS:Children aged 8 to 10 years were recruited from a primary school in Mexico. Participants completed 12 individual gaming sessions with FoodRateMaster in 6 weeks. A food knowledge questionnaire was administered before and after game play to assess the players' food knowledge. In addition, after the gaming sessions, the children's enjoyment and user experience satisfaction were evaluated using the EGameFlow questionnaire and the Game User Experience Satisfaction Scale (GUESS) questionnaire. RESULTS:We found significant positive associations for children's (n=60) posttest knowledge with enjoyment (r58=0.36, P=.005) and user experience satisfaction (r58=0.27, P=.04). The children's posttest knowledge scores were also positively correlated with challenge (r58=0.38, P=.003), knowledge improvement (r58=0.38, P=.003), and goal clarity (r58=0.29, P=.02) EGameFlow subscales and with narrative (r58=0.35, P=.006), creative freedom (r58=0.26, P=.04), and visual esthetics (r58=0.32, P=.01) GUESS subscales. Regression analysis indicated that the EGameFlow (F7,52=2.74, P=.02, R2=0.27) and the GUESS (F8,51=2.20, P=.04, R2=0.26) ratings significantly predicted the children's posttest knowledge scores. EGameFlow challenge (?=0.40, t52=2.17, P=.04) and knowledge improvement (?=0.29, t52=2.06, P=.04) subscales significantly contributed to predicting children's learning. None of the GUESS subscales significantly contributed to predicting children's learning. CONCLUSIONS:The findings of this study suggest that both enjoyment and user experience satisfaction for children aged 8 to 10 years were positively correlated with their learning and that were significant predictors of it. Challenge, knowledge improvement, narrative, creative freedom, and visual esthetics subscales correlated positively with children's learning. In addition, challenge and knowledge improvement contributed to predicting their learning. These results are relevant to consider during the design stages of serious games developed for young children's learning purposes.

Project description:BackgroundHospitalization offers an opportunity for healthcare providers to initiate advance care planning (ACP) conversations, yet such conversations occur infrequently. Barriers to these conversations include attitudes, skill, and time. Our objective was to develop a theory-based, provider-level intervention to increase the frequency of ACP conversations in hospitals.MethodsWe followed a systematic process to develop a theory-based, provider-level intervention to increase ACP conversations between providers and their hospitalized patients. Using principles established in Intervention Mapping and the Behavior Change Wheel, we identified a behavioral target, a theory of behavior change, behavior change techniques, and a mode of delivery. We addressed a limitation of these two processes of intervention development by also establishing a framework of design principles to structure the selection of intervention components. We partnered with a game development company to translate the output into a video game.ResultsWe identified willingness to engage in ACP conversations as the primary contributor to ACP behavior, and attitudes as a modifiable source of this willingness. We selected self-determination theory, and its emphasis on increasing autonomous motivation, as a relevant theory of behavior change and means of changing attitudes. Second, we mapped the components of autonomous motivation (i.e., autonomy, competence, and relatedness) to relevant behavior change techniques (e.g., identity). Third, we decided to deliver the intervention using a video game and to use the narrative engagement framework, which describes the use of stories to educate, model behavior, and immerse the user, to structure our selection of intervention components. Finally, in collaboration with a game development company, we used this framework to develop an adventure video game (Hopewell Hospitalist).ConclusionsThe systematic development of a theory-based intervention facilitates the mechanistic testing of the efficacy of the intervention, including the specification of hypotheses regarding mediators and moderators of outcomes. The intervention will be tested in a randomized clinical trial.

Project description:BackgroundSerious illness conversations may lead to care consistent with patients' goals near the end of life. The emergency department could serve as an important time and location for these conversations.AimTo determine the feasibility of an emergency department-based, brief motivational interview to stimulate serious illness conversations among seriously ill older adults by trained nurses.DesignA pre-/post-intervention study.Settings/participantsIn an urban, tertiary care, academic medical center and a community hospital from January 2021 to January 2022, we prospectively enrolled adults ⩾50 years of age with serious illness and an expected prognosis <1 year. We measured feasibility outcomes using the standardized framework for feasibility studies. In addition, we also collected the validated 4-item Advance Care Planning Engagement Survey (a 5-point Likert scale) at baseline and 4-week follow-up and reviewing the electronic medical record for documentation related to newly completed serious illness conversations.ResultsAmong 116 eligible patients who were willing and able to participate, 76 enrolled (65% recruitment rate), and 68 completed the follow-up (91% retention rate). Mean patient age was 64.4 years (SD 8.4), 49% were female, and 58% had metastatic cancer. In all, 16 nurses conducted the intervention, and all participants completed the intervention with a median duration of 27 min. Self-reported Advance Care Planning Engagement increased from 2.78 pre to 3.31 post intervention (readiness to "talk to doctors about end-of-life wishes," p < 0.008). Documentation of health care proxy forms increased (62-70%) as did Medical Order for Life Sustaining Treatment (1-11%) during the 6 months after the emergency department visit.ConclusionA novel, emergency department-based, nurse-led brief motivational interview to stimulate serious illness conversations is feasible and may improve advance care planning engagement and documentation in seriously ill older adults.
