NHPS & NHMS HPV Grant Survey December 9-10, 2013“Please indicate which of the following best describes your practice:” Fredenburg 2014 HPV Webinar
“Approximately how many prescribing clinicians see patients at your site?” “Which of the following best describes your practice location?” Fredenburg 2014 HPV Webinar
“Do the clinicians or other staff at your site routinely recommend the HPV vaccine for female or male adolescents at 11-12 years of age?” Fredenburg 2014 HPV Webinar
“Do the clinicians or other staff at your site routinely recommend the HPV vaccine for female adolescents at 11-12 years of age? If no, why not?” • do not see patient of that age group • The prison is for men, though we do have a few female inmates within the walls. • we do it at 14, 9th grade • Our adolescent population usually enters our program at age 14 and over. • parents sometimes decline • I did when still seeing out patients • not sure, time factor • I do not know about my partners • Not our age group patients. • Not seeing patients in this age group here • Not sure • Parents more receptive when girls are older around 14 or 15 when they may become sexually active and we are OK with this because our population is not active at such a young age.Also they are getting menactra/menveo around this age plus flu vaccine or hep A and the kids themselves want to space the imms out. • Most of the patients that we see have PCP office and receive that vaccine from them. • We don't see this age group • "They feel that it is a parents personal choice and that the parents should hae the option of having these kinds of discussions with their child first. • On the parents side they seem very reluctant at the earlier ages stating"" we don't need to deal with that yet"" presumingly meaning that they don't need to consider it as the child is not sexually active yet" • Active population is age 14 and older • physicians decided as a group what age group they wanted to start • The providers feel that the age is too young. We begin at age 13 • Sometimes at 11-12 but more commonly offered around 13 • I believe most offer at this time but recommendations are stronger in teen years ~ 14-16. • Not at 11 as we are giving 2-3 other vaccines then. We do start at 12 yrs usually. Fredenburg 2014 HPV Webinar
“Do the clinicians and office staff at your site routinely recommend the HPV vaccine for male adolescents at 11-12 years of age? If no, why not?” • NA • I do, but my partner does not. • I do, but do not know if my partners do. • slow uptake of evidence • They are not seen here prior to age 18 • usually do it later age 14 • The adolescents enter our program at age 14 and older. • same • This may have changed by now • Not yet but we should • not all feel it is that easy to convince the parents. • Same as for females • starting to • difficult subject on STD prevention in this age group. for girls, its more about cancer prevention and easier • I believe this is simply because it has not entered people's consciousness in the same way as for females • usually, there may be some incosistency when it comes to boys • Females only. • slow to adopt new recommendations • same • We do recommend and show them the information when a child comes in for a PE at that age (Physical Exam) and let them decide. There are patients that do not want the vaccine and they are quite clear about the reasons. • just not consistenly • not sure, actually • It is increasing but not something that is as remembered as the females. • same answer as for girls • Do not see male patients. • Followed by outside PCP • We don't see this age group. • forget to • Do not see patients of this age • the physicians decided as a group what age group they wanted to start • again they feel the age is too young • Most do, but some to not promote it as much as I think they should • None of them want it that early... better accepted later at 14-15 • see last comment Fredenburg 2014 HPV Webinar
“Are parents and adolescents knowledgeable about diseases associated with HPV and vaccination before the 11-12 year physical exam?” • “How have they learned this information?” • Sources cited media, internet, commercials, older siblings, general knowledge • Only 18 out of 41 (43.9%) of responses mentioned medical office as source of HPV info Fredenburg 2014 HPV Webinar
