Increasing Human Papillomavirus Vaccine Uptake in Low-Income, Ethnic Minority Adolescents in Los Angeles County
The primary aim of the project is to increase human papillomavirus (HPV) vaccine receipt rates among low-income, ethnic minority adolescents (girls and boys 11-17 years of age) in Los Angeles County. We will accomplish this goal by implementing and rigorously evaluating interventions in multiple venues that serve our target population, including the Los Angeles County Department of Public Health (LACDPH) and two large Federally Qualified Health Centers (FQHCs).
Our hypotheses are:
Primary hypothesis:
The intervention group will have a higher rate of HPV vaccine initiation at follow-up compared to the control group.
Secondary hypothesis:
- The intervention group will have higher vaccine completion rates (3 doses) at follow-up compared to the control group.

Detailed Description
The primary aim of the project is to increase HPV vaccine receipt rates among low-income, ethnic minority adolescents (girls and boys ages 9-17 years) in LA County. We will accomplish this goal by implementing and rigorously evaluating interventions in multiple venues that serve our target population, including the Los Angeles County Department of Public Health (LACDPH) and two large Federally Qualified Health Centers (FQHCs).
Our hypotheses are:
Primary hypothesis:
The intervention group will have a higher rate of HPV vaccine initiation at follow-up compared to the control group.
Secondary hypothesis:
- The intervention group will have higher vaccine completion rates (3 doses) at follow-up compared to the control group.
Recruitment Venue 1: Los Angeles County Department of Public Health. At the LACDPH, the multi-component intervention will be directed at caregivers of age-eligible adolescents (11-17 years) and include brief individually-tailored telephone education, referral to a clinic offering low cost/free vaccine, and a mailed brochure. The control group will receive usual care and a standard Centers for Disease Control and Prevention (CDC) HPV vaccine fact sheet.
Additional secondary hypotheses for this recruitment venue include:
- The intervention group will have higher knowledge of HPV and the HPV vaccine than the control group.
- The intervention will have a greater effect on the more acculturated than less acculturated participants (moderator effect).
- The intervention will exert its effect on vaccine receipt by increasing knowledge and reducing barriers (mediator effects).
This recruitment venue will utilize a two-arm time-randomized (on-off) controlled design to assess the effect of a multi-component intervention targeting mothers and fathers, to increase HPV vaccine uptake among their adolescents (ages 11-17). Hotline users will be randomized into the intervention or control condition on an alternating (on/off) weekly schedule. Eligible participants will complete a baseline telephone interview. Immediately following the baseline interview, participants calling during intervention weeks will receive the individually-tailored multi-component intervention, including tailored education and clinic referral. A tailored print intervention will also be mailed to intervention participants. All participants will be re-contacted at 3 months and 9 months for telephone follow-up interviews. Control group participants will receive the intervention after the 9-month follow-up. Prior to study protocol implementation, about 25-50 individuals will be recruited to pre-test the baseline survey in different languages (English, Spanish, Chinese, Armenian) to ensure the baseline questionnaires are similar in content across languages and the questions are clear.
The study site will enroll men and women of diverse racial-ethnic backgrounds from the Office of Women's Health (OWH) women's health telephone hotline database. The database includes contact information about adult women LA County residents who telephoned a 1-800 hotline to receive information and referrals about women's health issues, including cervical cancer and cervical cancer screening. Male callers also use the hotline. The OWH has promoted the hotline through partnerships with over 300 community-based organizations. Recruitment of callers from the database will consist of operators calling women to invite them to be screened for study eligibility. Recruitment of new hotline callers will take place during their first contact with the hotline. Upon receiving an incoming call, operators will first respond to the caller's request using routine hotline protocols which include screening for income eligibility (<200% of poverty) for county services. Following this, operators invite the caller to be screened for study eligibility. Eligible participants will be asked to complete the baseline interview.
Callers will be randomized to the intervention or control condition on alternating weeks (on-off or time randomized design). This randomization scheme was selected in close consultation with OWH to ensure the integrity of the randomization process and minimize disruption of routine hotline operation. The telephone intervention will be delivered immediately following the baseline telephone interview to participants calling during intervention weeks. The intervention is based on the Health Behavior Framework and pilot study findings and incorporates individual-level tailoring. The three segments of the telephone intervention include: 1) basic information about the HPV vaccine; 2) individually-tailored information to address each participant's primary concerns regarding the vaccine; 3) individually-tailored referral to a local clinic where free/low cost vaccine is available.
Baseline interviews (10-15 mins) will be conducted immediately following the eligibility screener and the verbal informed consent, via a Computer Assisted Telephone Interviewing System. All eligible subjects who complete the baseline interview will receive brief (<10 mins) 3 and 9-month follow-up telephone interviews.
Following the 3-month interviews, half of intervention participants will receive a "booster" intervention wherein we will repeat the clinic referral procedure/language given during the intervention at baseline. Intervention participants will be randomized to the "booster" or no "booster" condition based on the order in which they completed the baseline survey.
Recruitment Venue 2: AltaMed Health Services Corporation. At AltaMed Health Services Corporation, the largest federally qualified health center in the nation, we will implement a multi-level intervention that includes patient (i.e., caregiver) and provider reminders, physician, nurse, and other staff training regarding the HPV vaccine and processes and procedures for its delivery. We will utilize a quasi-experimental study design to assess the effect of this multi-level intervention to increase HPV vaccine initiation and completion among adolescents (ages 9-17). Eight clinic sites that serve the majority of AltaMed's adolescent population will be matched based on the size of the adolescent population served and baseline HPV vaccination rates. We will randomly assign matched paired clinics to either the intervention (n=4) or usual care group (n=4).
Clinics assigned to the usual care condition will only receive: (1) the standing order for the HPV vaccine, which authorizes non-physician providers to assess adolescents' immunization eligibility and administer the HPV vaccine without a physician examination or order and (2) a required web-based training module for medical assistants and nurses containing basic information on HPV, the HPV vaccine, and standing order implementation.
In addition to usual care activities, intervention clinics will receive the following: (1) health care provider training on the importance of HPV vaccination and a strong provider recommendation, strategies to appropriately frame the HPV vaccine conversation, and recommended processes and procedures for vaccine delivery; (2) staff training on the importance of HPV vaccination, strategies to promote uptake of the vaccine, and recommended processes and procedures for vaccine delivery; (3) patient and provider reminders to promote completion of the three-dose vaccine series; and (4) organizational strategies to improve processes for vaccine delivery, in addition to usual care activities.
The intervention will be developed in close collaboration with administrative leadership and providers, who will provide input at each stage of the design, implementation, and evaluation process. A physician vaccine champion from the organization will assist with the development of and lead a one-hour, in-person provider presentation and discussion. For the staff training presentation, nurse managers will be convened regularly to discuss processes for HPV and general standing order implementation, strategies to optimize clinical workflow and increase follow-up, and development of back office staff training. Using a train-the-trainer approach, the nurse mangers will lead the approximate one-hour presentation and discussion at their respective clinics. They will also monitor process implementation through direct staff observation and quality reports and retrain staff as needed.
In addition to provider and staff trainings, organizational strategies at intervention sites will include implementation of standard practices for HPV vaccine delivery that complement existing clinical workflow. At intake, back office staff will check vaccination history at each visit, implement needed standing orders, inform caregivers of vaccines due, and notify the provider of vaccines ordered. During the provider encounter, providers will confirm recommended vaccinations and recommend the HPV vaccine as part of other routine vaccines. At check-out, back office staff will administer vaccines, schedule a visit for the second dose, and provide caregivers both a standard appointment card and an intervention site reminder magnet. A clinic provider vaccine champion will be identified to monitor implementation, adapt processes, and serve as a resource at intervention sites.
To estimate intervention effects, we will use data extracted from AltaMed's electronic medical record system to measure HPV vaccine initiation and completion rates among adolescents ages 9-17 at baseline and at regular intervals post intervention implementation. Patient, provider and clinic factors associated with vaccine receipt will also be examined.
Recruitment Venue 3: Northeast Valley Health Corporation. At Northeast Valley Health Corporation, another large federally qualified health center, we will implement and evaluate the effects of three different clinic-level reminder systems (mailed letter, automated/robo telephone call, text message) on HPV vaccine initiation and completion among adolescents (ages 12-13).
We will utilize a quasi-experimental study design. This FQHC comprises 8 sites that provide primary care for medically underserved adults and adolescents in LA County. We will select 6 clinics matched on baseline vaccine receipt rates and other clinic characteristics and randomly assign matched paired clinics to usual care or one of the three reminder system interventions: mailed letter, automated/robo telephone call, or text message. Eligible caregivers of adolescent boys and girls ages 12-13 who have received no doses or only one dose of the HPV vaccine will be identified through Northeast Valley's electronic medical record and population health management systems.
After identification of eligible patients (i.e. caregivers), the centralized call center will generate a standard letter and the automated/robocalls. A third-party vendor will send the text messages. The reminder content will be adapted from existing clinical message scripts and include a short message, which will be consistent across all modalities, on the importance of HPV vaccination and how to make an appointment. Reminder messages will be delivered in the patients' preferred language (either English or Spanish). The same reminder type (either letter, call, or text message) will be used on up to two occasions: once at baseline and a second time approximately one month after baseline for those who have not yet received the targeted vaccine dose. To monitor receipt of reminders, number of unaccepted telephone calls, returned letters, and stopped text messages will be monitored. Clinics assigned to the usual care condition will receive standard of care, which does not include any systematic reminders.
Similar to the AltaMed FQHC site, to estimate intervention effects, we will use data extracted from electronic medical records to measure HPV vaccine initiation and completion rates at baseline and at regular intervals post intervention implementation.
