Brief summary

This clinical trial compares usual care to interpersonal communication training and vaccination workflow training, alone or in combination, for improving communication about and recommendations for human papillomavirus (HPV) and other vaccinations in pharmacies. Low HPV vaccination in the United States has placed unvaccinated children at risk of developing cancers as adults that could have been prevented. Pharmacies can be convenient for vaccination because they are open longer hours, have shorter wait times, can see patients without appointments and may cost less. However, many people are not aware that vaccination is available in pharmacies and some pharmacies lack the commitment from staff to vaccinate or may not have protocols in place for vaccination. Proactive communication approaches to recommending HPV vaccination have been shown to be effective in medical offices but have not been tested in the pharmacy setting. Interpersonal communication training incorporates the 5 A's (assess, advice, agree, assist and arrange) behavioral counseling framework to strongly recommend HPV and other vaccines and effectively answer any questions or concerns about vaccination. Vaccination workflow training establishes vaccination decision support strategies that pharmacies use to improve vaccination workflows. Interpersonal communication training and vaccination workflow training alone or in combination may improve communication and recommendations for HPV vaccination and increase HPV vaccination in pharmacies.

Detailed description

OUTLINE: OBJECTIVE 1: Parents are randomized to receive messages on 1 of 6 topics. TOPIC I (SAFETY AND SIDE EFFECTS): Parents review 4 messages on safety and side effects and complete a survey over 15-20 minutes in support of intervention refinement on study. TOPIC II (VACCINE EFFECTIVENESS): Parents review 4 messages on vaccine effectiveness and complete a survey over 15-20 minutes in support of intervention refinement on study. TOPIC III (SEXUAL ACTIVITY): Parents review 4 messages on sexual activity and complete a survey over 15-20 minutes in support of intervention refinement on study. TOPIC IV (HPV VACCINE FOR BOYS): Parents review 4 messages on HPV vaccine for boys and complete a survey over 15-20 minutes in support of intervention refinement on study. TOPIC V (AGE TO START VACCINE): Parents review 4 messages on age to start vaccine and complete a survey over 15-20 minutes in support of intervention refinement on study. TOPIC VI (SCHOOL ENTRY REQUIREMENTS): Parents review 4 messages on school entry requirements and complete a survey over 15-20 minutes in support of intervention refinement on study. OBJECTIVE 2: Pharmacies are assigned to a strata of 4 pharmacies with similar characteristics and pharmacies within each strata are randomized to 1 of 4 groups. GROUP I (CONTROL): Pharmacy staff provide vaccinations per usual care. GROUP II (STRATEGY A): Pharmacy staff receive interpersonal communication training over 120 minutes and provide vaccinations using the interpersonal communication strategy. GROUP III (STRATEGY B): Pharmacy staff receive the vaccination workflow training and provide vaccinations using the vaccination workflow training strategy. GROUP IV (STRATEGIES A AND B): Pharmacy staff receive interpersonal communication training as well as vaccination workflow training and provide vaccinations using both the interpersonal communication strategy and the vaccination workflow training strategy.

Design outcomes

Primary

MeasureTime frameDescription
Perceived fit, relevance, or compatibility of human papillomavirus (HPV) vaccination or the communication strategy for a given practice site, provider, or patient (Appropriateness: Pharmacy Staff)At baseline, 2 months post-training delivery, and 12 months post-training deliveryAssessed via survey. The survey was developed by study researchers based upon the Implementation Outcomes Questionnaire (IOQ) (Livet M, et al. 2021.). It was used to capture change of participants' perceptions pre/post training. There are five answers to each survey question and each answer is given a score from 1 to 5, with 1 being strongly disagree and 5 being strongly agree. Higher numerical scores on the 5-point scale indicate greater level of agreement that the intervention was appropriate to support HPV vaccination delivery to children ages 9-17. Study researchers will calculate the average scale based on numeric scores. For questions that are asked in a reverse fashion, study researchers will reverse the score accordingly.
Perceived fit, relevance, or compatibility of human papillomavirus (HPV) vaccination or the communication strategy for a given practice site, provider, or patient (Appropriateness: Parents)The outcome will be measured at one time point, at a time frame from the date of vaccine administration to up to 8 weeks after that vaccine administration dateAppropriateness outcomes will be assessed via survey to parents following their child's HPV vaccination. The four questions to evaluate appropriateness are sourced from evidence-based assessments of Intervention Appropriateness Measure (IAM) from Weiner et al. (2017). There are five answers to each survey question and each answer is given a score from 1 to 5, with 1 being strongly disagree and 5 being strongly agree. Higher numerical scores on the 5-point Likert scale indicate greater level of agreement that the intervention was appropriate in supporting HPV vaccination delivery to children ages 9-17.
Perceptions that HPV vaccinations or the communication strategy is agreeable, palatable, or satisfactory (Acceptability: Pharmacy Staff)At baseline, 2 months post-training delivery, and 12 months post-training deliveryAssessed via survey. The survey was developed by study researchers based upon the Implementation Outcomes Questionnaire (IOQ) (Livet M, et al. 2021.). It was used to capture change of participants' perceptions pre/post training. There are five answers to each survey question and each answer is given a score from 1 to 5, with 1 being strongly disagree and 5 being strongly agree.

Extent to which the communication strategy was successfully implemented and used at pharmacies to support HPV vaccine delivery (Feasibility)At baseline, 2 months post-training delivery, and 12 months post-training deliveryAssessed via survey. The survey was developed by study researchers based upon the Implementation Outcomes Questionnaire (IOQ) (Livet M, et al. 2021.). It was used to capture change of participants' perceptions pre/post training. There are five answers to each survey question and each answer is given a score from 1 to 5, with 1 being strongly disagree and 5 being strongly agree.

Study researchers will calculate the average scale based on numeric scores. For questions that are asked in a reverse fashion, study researchers will reverse the score accordingly.
HPV vaccination delivery (Fidelity: Pharmacy Staff)Up to completion of the 12 month trial periodWill conduct audits of the pharmacy electronic records to assess adherence to HPV vaccination protocols, by comparing the proportion of HPV vaccines given "on time" to children aged 9-10 and 11-12 versus "late" to children aged 13-17.
HPV vaccination delivery (Fidelity: Parents)The outcome will be measured at one time point, at a time frame from the date of vaccine administration to up to 8 weeks after that vaccine administration dateHPV vaccine delivery fidelity will be assessed via survey to parents following their child's HPV vaccination. Parents will be asked to indicate which of seven, if any, supportive vaccination behaviors occurred during their visit in a "select all that apply" format. The seven experiences correspond to vaccination behaviors that have been shown in formative research to support HPV vaccine delivery and parents' perceptions of acceptability and appropriateness of HPV vaccination workflows using the 5As Behavioral Counseling Model (Sturgiss et al. 2017). The supportive behaviors include eligibility screening, recommendation, counseling, documentation and record retrieval support, PCP reporting, and scheduling for follow up. To summarize the overall fidelity to the workflow per respondent, study researchers will create a composite "fidelity score" by summing the number of behaviors each parent endorsed (range: 0-7). Higher scores will indicate greater adherence to the recommended workflow.
Self-efficacyAt baseline, 2 months post-training delivery, and 12 months post-training deliveryAssessed via survey. The survey was developed by study researchers and includes validated measures from a 31-item medication therapy management (MTM) efficacy scale (Martin B, et al. 2010) and a statewide survey of healthcare providers (McRee AL, et.al. 2014). It will be used to capture change of participants' perceptions pre/post training. For this outcome there are five answers to each survey question reflecting how confident the respondent is in performing tasks related to providing HPV vaccinations to children, and each answer is given a score from 1 to 5, with 1 being not at all confident/strongly disagree and 5 being completely confident/strongly agree. Higher numerical scores on the 5-point scale reflect higher levels of self-efficacy or confidence in personal ability to complete vaccination process actions. Study researchers will calculate the average scale based on numeric scores.
