Adolescent Immunization Delivery in School-Based Health Centers: A National Survey

PURPOSE Vaccinating adolescents in a variety of settings may be needed to achieve high vaccination coverage. School-based health centers (SBHCs) provide a wide range of health services, but little is known about immunization delivery in SBHCs. The objective of this investigation was to assess, in a national random sample of SBHCs, adolescent immunization practices and perceived barriers to vaccination. METHODS One thousand SBHCs were randomly selected from a national database. Surveys were conducted between November 2007 and March 2008 by Internet and standard mail. RESULTS Of 815 survey-eligible SBHCs, 521 (64%) responded. Of the SBHCs, 84% reported vaccinating adolescents, with most offering tetanus-diphtheria-acellular pertussis, meningococcal conjugate, and human papillomavirus vaccines. Among SBHCs that vaccinated adolescents, 96% vaccinated Medicaid-insured and 98% vaccinated uninsured students. Although 93% of vaccinating SBHCs participated in the Vaccines for Children program, only 39% billed private insurance for vaccines given. A total of 69% used an electronic database or registry to track vaccines given, and 83% sent reminders to adolescents and/or their parents if immunizations were needed. For SBHCs that did not offer vaccines, difficulty billing private insurance was the most frequently cited barrier to vaccination. CONCLUSIONS Most SBHCs appear to be fully involved in immunization delivery to adolescents, offering newly recommended vaccines and performing interventions such as reminder/recall to improve immunization rates. Although the number of SBHCs is relatively small, with roughly 2000 nationally, SBHCs appear to be an important vaccination resource, particularly for low income and uninsured adolescents who may have more limited access to vaccination elsewhere.

Influenza and Pertussis Vaccination Among Pregnant Women and Their Infants' Close Contacts: Reported Practices and Attitudes.

Background: Our objectives were to describe the receipt of influenza and tetanus-diphtheria-acellular pertussis (Tdap) vaccines among postpartum women and their close contacts and the factors associated with cocooning. Methods: A survey between February 2013 and April 2013 of 613 postpartum women from 9 obstetrics practices assessed vaccine receipt among respondents and close contacts, demographics and 5 domains of health beliefs (benefits, barriers, susceptibility, severity and social norms). Multivariable models assessed the association of these factors with Tdap or influenza ”cocooning,” defined as the mother plus at least 1 close contact of her newborn receiving the vaccine. Results: The response rate was 45%; 61% of mothers reported that they and at least 1 close contact of their newborn had received influenza vaccine, and 67% reported this for Tdap. Infants whose mothers received influenza vaccine had a mean of 2.8 close contacts who also received influenza vaccine versus a mean of 0.9 contacts for infants whose mothers did not receive influenza vaccine (P < 0.0001). Infants whose mothers received Tdap vaccine had an average of 2.4 contacts who also received it versus 0.8 for infants whose mothers did not receive Tdap (P < 0.0001). Factors associated with influenza and Tdap cocooning included obstetrician recommendation, high perceived benefits, low perceived barriers and perceived susceptibility to disease. For Tdap, race/ethnicity was associated with cocooning (Hispanic/Latino, adjusted odds ratio 0.26, 95% confidence interval: 0.10–0.64 referent to White). Conclusion: Maternal vaccination and obstetrician recommendation are associated with infant cocooning. Interventions to increase cocooning of infants should focus on encouraging strong provider recommendations, increasing maternal knowledge of disease risk and addressing identified barriers. Reasons for possible racial/ethnic differences should be further explored.

Acceptability of human papillomavirus vaccines among women older than 26 years

OBJECTIVE To examine older womens (>26 years) acceptance of the human papillomavirus (HPV) vaccine, and factors associated with this outcome. STUDY DESIGN A convenience sample of 872 women age 26-77 years were surveyed regarding the likelihood they would accept the HPV vaccine if offered to them by their provider, and factors associated with this outcome. Binomial regression, Chi square and MacNemars analyses were used to determine associations of this outcome with demographic, attitudinal, and experiential variables. RESULTS The response rate was 60.8%. Half the respondents indicated they would want the vaccine, even if they had to pay for it. In multivariable analyses, the only factor associated with wanting the vaccine was higher self-reported knowledge about HPV (risk ratio 1.43, 95% Confidence Interval 1.12, 1.83). A majority of participants also believed that older women in general would want the vaccine if it were covered by insurance. However, this perspective was significantly diminished if the vaccine had to be paid for out of pocket (97% vs. 22% for 26-45 year olds; 84% vs. 20% for 46-65 year olds, 60% vs. 8% for 66+ year olds, p<0.001). Nearly all (93%) believed primary care physicians should routinely discuss the vaccine with older women. CONCLUSIONS A high proportion of women over 26 would want the HPV vaccine if offered by their provider, even if they had to pay for it out of pocket. This suggests that if providers were to routinely offer the HPV vaccine to their older patients, many women would choose to get vaccinated.

Evidence-based vaccination strategies in obstetrics and gynecology settings: Current practices and methods for assessment.

Obstetrician-gynecologists have the potential to play an important role in the delivery of immunizations to women. However, despite national recommendations, immunization rates among pregnant women and adults in general remain low. Pragmatic immunization delivery trials are needed to demonstrate how best to deliver vaccines in such settings. We report the development and implementation of 2 novel methodologies for immunization delivery research and quality improvement in such settings. The first was the development and application of a 47-point Immunization Delivery Scale that formally assessed variability among practices in their engagement in a variety of evidence-based practices for improving immunization rates. The second was a covariate-constrained randomization technique – a method for achieving balance between study arms in cluster-randomized trials that is especially applicable to pragmatic trials.. To best achieve meaningful and interpretable findings, we recommend use of these or similar techniques in future immunization research and quality improvement projects in OB/GYN settings.

Improving Provider Communication about HPV Vaccines for Vaccine-Hesitant Parents Through the Use of Motivational Interviewing

Human papillomavirus (HPV) vaccine uptake is below that of other routine adolescent vaccines. This is due in part to the fact that the HPV vaccine is often not routinely recommended by providers to all eligible adolescents. While providers’ recommendations are crucial, even a strongly stated recommendation can be insufficient among HPV vaccine-hesitant parents. Providers must be prepared to respond to parental concerns following giving the recommendation for the HPV vaccine. This paper presents the analysis of implementation of an intervention aimed at improving provider communication with HPV vaccine-hesitant parents. Healthcare providers and staff at eight pediatric and family medicine clinics received communication training that included motivational interviewing (MI) techniques. Process evaluation in the form of serial surveys, as well as program evaluation in the form of focus groups with participating providers and staff, assessed the perceived efficacy of the intervention. Outcomes included time spent discussing the HPV vaccine during clinical visits, providers’ self-efficacy for addressing parental HPV vaccine hesitancy, and their general perceptions of the effectiveness of MI techniques. Overall, findings indicate the intervention improved providers’ communication with HPV vaccine-hesitant parents and providers reported the use of MI played a central role in improved HPV vaccine acceptance. Lessons learned and recommendations for future interventions are also discussed.

Facilitators and barriers to the use of standing orders for vaccination in obstetrics and gynecology settings.

BACKGROUND: Many young and middle‐aged women receive their primary health care from their obstetrician‐gynecologists. A recent change to vaccination recommendations during pregnancy has forced the integration of new clinical processes at obstetrician‐gynecology practices. Evidence‐based best practices for vaccination delivery include the establishment of vaccination standing orders. OBJECTIVES: As part of an intervention to increase adoption of evidence‐based vaccination strategies for women in safety‐net and private obstetrician‐gynecology settings, we conducted a qualitative study to identify the facilitators and barriers experienced by obstetrician‐gynecology sites when establishing vaccination standing orders. STUDY DESIGN: At 6 safety‐net and private obstetrician‐gynecology practices, 51 semistructured interviews were completed by trained qualitative researchers over 2 years with clinical staff and vaccination program personnel. Standardized qualitative research methods were used during data collection and team‐based data analysis to identify major themes and subthemes within the interview data. RESULTS: All study practices achieved partial to full implementation of vaccine standing orders for human papillomavirus, tetanus diphtheria pertussis, and influenza vaccines. Facilitating factors for vaccine standing order adoption included process standardization, acceptance of a continual modification process, and staff training. Barriers to vaccine standing order adoption included practice‐ and staff‐level competing demands, pregnant womens preference for medical providers to discuss vaccine information with them, and staff hesitation in determining HPV vaccine eligibility. CONCLUSIONS: With guidance and commitment to integration of new processes, obstetrician‐gynecology practices are able to establish vaccine standing orders for pregnant and nonpregnant women. Attention to certain process barriers can aid the adoption of processes to support the delivery of vaccinations in obstetrician‐gynecology practice setting, and provide access to preventive health care for many women.

Evaluation of the Implementation of a Multi-Component Intervention to Improve Healthcare Provider Communication about HPV Vaccination

OBJECTIVE To evaluate the relative use, usefulness, and facilitators and barriers to use as perceived by providers of 5 different components in a human papillomavirus vaccine communication intervention-which was found to be effective at improving human papillomavirus vaccination rates. METHODS Four serial surveys of 108 providers (doctor of medicine, nurse practitioner, or doctor of osteopathic medicine) from intervention clinics involved in the study assessed the use and usefulness of the 5 communication intervention components during a 12-month period. RESULTS Survey response rates were 79% to 86%. The fact sheet (64%-77%) and motivational interviewing techniques (MI; 86%) were the most used components-use was sustained during the 12-month period. These components also were perceived as somewhat or very useful by most providers, and this perceived usefulness increased over time (very or somewhat useful at end of study, 97% fact sheet, 98% MI, respectively). Although fewer providers reported using the Web site (15%-42%), or disease images (6%-17%), when these were used, most providers (67%-87%) felt they were somewhat or very useful. The decision aid was not used frequently (17%-41% of providers), and 43% of providers felt it was not very or not at all useful. Facilitators and barriers were identified for each component. The fact sheet and MI were perceived as the easiest to integrate into the clinic workflow. CONCLUSIONS The fact sheet and MI were the most used and most useful intervention components. Both were easy to integrate into clinic workflow, and their use was sustained over time. Dissemination of similar interventions in the future should focus on these 2 specific components.

Provider and Parent Perspectives on Enhanced Communication Tools for Human Papillomavirus Vaccine–Hesitant Parents

OBJECTIVE Human papillomavirus (HPV) vaccine initiation and completion rates remain far below the Healthy People 2020 goal, suggesting that additional tools and training may be needed to help medical staff provide a quality recommendation. As part of a larger pragmatic trial, we conducted a qualitative study to understand how a multifaceted communication intervention used by medical staff with HPV vaccine-hesitant parents can improve HPV vaccination rates in the primary care setting. METHODS At 8 primary care intervention clinics in the Denver metro area, medical staff and parents of adolescent boys and girls ages 11 to 17 years eligible to start the HPV vaccine series at a recent well care visit were recruited for study participation. Focus groups with medical staff and in-depth interviews with hesitant parents were conducted during the post-intervention period. All data were recorded, transcribed, and analyzed using established qualitative methods. RESULTS Twenty parents and 46 medical staff participated. All parents and medical staff felt that the overall intervention was beneficial and should continue to be used and preferred the HPV vaccine fact sheet component. Medical staff reported that communication trainings (intervention component) that taught a presumptive approach and motivational interviewing were the most beneficial for introducing the HPV vaccine and for countering HPV vaccine hesitancy, respectively. Least favorable components were the decision aid, disease images, and parent website. CONCLUSIONS Select components of a multifaceted communication intervention were seen as beneficial to HPV vaccine-hesitant parents and medical staff. Future studies should look at how to implement these intervention components in a greater number of primary care settings.
