- Abstract
Objectives: In 2008, a national human papillomavirus (HPV) vaccination programme for females was introduced in England using the bivalent vaccine (HPV16 and 18 only). In 2012, the programme changed to offer the quadrivalent vaccine that includes protection against the two HPV types that cause the majority of anogenital warts (AGW; HPV6 and 11). We present data reporting AGW diagnoses in sexual health clinics (SHCs) in England to the end of 2017, including diagnoses among birth cohorts offered the quadrivalent vaccine., Methods: Using data from all SHCs across England, we performed ecological analyses to consider rates of AGW diagnoses by age, gender and sexual orientation. We tested for trends over time of diagnoses of AGW in young females, heterosexual males, and men who have sex with men (MSM) between the ages of 15 and 24 years during both bivalent (2009 to 2013) and quadrivalent (2014 to 2017) vaccine time periods using Poisson regression., Results: Between 2014 and 2017, there was strong evidence for a decreasing trend in the rate of AGW diagnoses at SHC among females aged 15-17 years from 257.5 to 45.7 per 100 000 population (82.3% decline) and same aged heterosexual males from 59.1 to 19.1 per 100 000 population (67.7% decline). The reductions in the incidence of AGW diagnoses in MSM aged 15-17 years were less clear (decreased by 13.6% between 2014 and 2017, from 129.9 to 112.2 per 100 000 population)., Conclusions: The moderate, unexpected declines in AGW seen since the introduction of a high-coverage HPV vaccination programme using the bivalent vaccine are being followed, as expected, by much larger declines among females offered the quadrivalent vaccine and same-aged heterosexual males. Surveillance plans are in place to continue to monitor AGW diagnoses to evaluate the impact of both female and targeted MSM HPV vaccination on early disease outcomes., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2019.

- Abstract
Background: Many economic evaluations of human papillomavirus vaccination should ideally consider multiple disease outcomes, including anogenital warts, respiratory papillomatosis and non-cervical cancers (eg, anal, oropharyngeal, penile, vulvar and vaginal cancers). However, published economic evaluations largely relied on estimates from single studies or informal rapid literature reviews., Methods: We conducted a systematic review of articles up to June 2016 to identify costs and utility estimates admissible for an economic evaluation from a single-payer healthcare provider's perspective. Meta-analyses were performed for studies that used same utility elicitation tools for similar diseases. Costs were adjusted to 2016/2017 US$., Results: Sixty-one papers (35 costs; 24 utilities; 2 costs and utilities) were selected from 10 742 initial records. Cost per case ranges were US$124-US$883 (anogenital warts), US$6912-US$52 579 (head and neck cancers), US$12 936-US$51 571 (anal cancer), US$17 524-34 258 (vaginal cancer), US$14 686-US$28 502 (vulvar cancer) and US$9975-US$27 629 (penile cancer). The total cost for 14 adult patients with recurrent respiratory papillomatosis was US$137 601 (one paper).Utility per warts episode ranged from 0.651 to 1 (12 papers, various utility elicitation methods), with pooled mean EQ-5D and EQ-VAS of 0.86 (95% CI 0.85 to 0.87) and 0.74 (95% CI 0.74 to 0.75), respectively. Fifteen papers reported utilities in head and neck cancers with range 0.29 (95% CI 0.0 to 0.76) to 0.94 (95% CI 0.3 to 1.0). Mean utility reported ranged from 0.5 (95% CI 0.4 to 0.61) to 0.65 (95% CI 0.45 to 0.75) (anal cancer), 0.59 (95% CI 0.54 to 0.64) (vaginal cancer), 0.65 (95% CI 0.60 to 0.70) (vulvar cancer) and 0.79 (95% CI 0.74 to 0.84) (penile cancer)., Conclusions: Differences in values reported from each paper reflect variations in cancer site, disease stages, study population, treatment modality/setting and utility elicitation methods used. As patient management changes over time, corresponding effects on both costs and utility need to be considered to ensure health economic assumptions are up-to-date and closely reflect the case mix of patients., Competing Interests: Competing interests: MJ reports grants from the National Institute for Health Research during the conduct of the study., (© Author(s) (or their employer(s)) 2019.
