A cross-sectional study estimating the burden of illness related to genital warts in South Korea.

ABSTRACT:

Objectives

Estimate the prevalence of genital warts (GW) and GW-related healthcare resource use and costs among male and female patients seeking treatment in South Korea.

Design

To estimate GW prevalence, physicians in five major South Korean regions recorded daily logs of patients (n=71?655) seeking care between July 26 and September 27, 2011. Overall prevalence estimates (and 95% CIs) were weighted by the estimated number of physicians in each specialty and the estimated proportion of total patients visiting each specialist type. Healthcare resource use was compared among different specialties. Corresponding p values were calculated using Mann-Whitney U tests.

Setting

The database covers 5098 clinics and hospitals for five major regions in South Korea: Seoul, Busan, Daegu, Gwangju and Daejeon.

Participants

Primary care physicians (general practice/family medicine), obstetricians/gynaecologists, urologists and dermatologists with 2-30 years' experience.

Results

The estimated overall GW prevalence was 0.7% (95% CI 0.7% to 0.8%). Among women, GW prevalence was 0.6% (95% CI 0.6% to 0.7%); among men prevalence was 1.0% (95% CI 0.9% to 1.0%), peaking among patients aged 18-24 years. Median costs for GW diagnosis and treatment for male patients were US$58.2 (South Korean Won (KRW) ?66?857) and US$66.3 (KRW?76?113) for female patients.

Conclusions

The estimated overall GW prevalence in South Korea was 0.7% and was higher for male patients. The overall median costs associated with a GW episode were higher for female patients than for male patients.

Project description:BackgroundHuman papillomavirus (HPV) infections are the etiologic agents of genital warts (GW). HPV is one of the most frequent sexually transmitted viral infections, and nearly 65% of individuals with partners who have GW also develop GW. In Russia, as in many other countries, overall GW prevalence data are scarce. Given the lack of Russian data, our study estimated GW prevalence in physician practices and GW-related health care resource use in Russia among male and female patients aged 18-60 years.MethodsRussian physicians recorded daily patient logs for a two-week period and conducted a 30-minute survey to estimate GW prevalence and related resource use between January and June 2012. Age, gender, and GW diagnosis status was recorded. Prevalence was obtained for each physician and calculated into a single estimate across all physician types. Overall prevalence estimate and 95% confidence interval were weighted by the estimated number of physicians in each specialty and the proportion of total patients visiting each specialist type. Health care resource use was reported and compared among different physician specialties.ResultsThe overall GW prevalence estimate was 9162 cases per 100 000 for male and female patients aged 18-60 years, with 9917 for obstetrician/gynecologists (OB/GYN), 8298 for urologists (URO), and 7833 for dermatologists (DERM). For males, GW prevalence was 8769 cases per 100 000, with the highest prevalence in the 30-34 age group. In females, GW prevalence was 9304 cases per 100 000, with the highest prevalence in the 18-24 age group. Among overall existing GW cases, 63.1% were recurrent and 34.2% were resistant. For all patients in our study, GW prevalence was higher in females. Male patients had the highest prevalence for those aged 30-34 years, and female patients for those aged 18-24 years. These results are consistent with data reported in other countries. Study limitations include estimates and results representative of the urban population of Russia. Despite its limitations, this study provides a GW prevalence estimate in Russia not previously available.ConclusionsGW is a significant public health concern in Russia, and the GW prevalence was higher in female patients compared to male patients.

Project description:ObjectivesTo estimate self-reported human papillomavirus (HPV) disease-related psychosocial impact among male and female patients in South Korea.DesignIn this multicentre cross-sectional study, psychosocial impacts were estimated using a one-time survey capturing HPV Impact Profile (HIP) results, CuestionarioEspecifico en Condilomas Acuminados (CECA; in Spanish)-'Specific questionnaire for Condylomata Acuminata' and the EuroQol-5 Dimension (EQ-5D) surveys. Student's t-tests or Mann-Whitney U tests were used for continuous comparisons; χ2 or Fisher's exact tests were applied for categorical comparisons.Setting5098 clinics throughout Seoul, Busan, Daegu, Kwangju and Daejeon (South Korea).ParticipantsPatients with and without genital warts (GW) (males) and selected HPV diseases (females) visiting primary care physicians, obstetricians/gynaecologists, urologists and dermatologists with 2-30 years experience.ResultsOf 150 male and 250 female patients, HIP scores showed 85.3% of male patients with GW and 32.0% without reported moderate psychological impact (p<0.0001). In categorised total scores, 88.5% of female patients with and 66.0% without selected HPV-related diseases reported moderate or high psychological impacts (p=0.0004). In the CECA questionnaire, male patients had mean (SD) scores of 10.51 (3.79) in 'emotional health' and 15.90 (6.13) in 'sexual activity'. Female patients with GW reported lower scores in both dimensions with mean scores of 7.18 (4.17) in 'emotional health' and 10.97 (5.80) in 'sexual activity' (p<0.0001), indicating worse health-related quality of life (HRQoL). For the EQ-5D, male patients with GW reported lower mean Visual Analogue Scale (VAS) scores than those without (75.1 vs 81.13, p<0.0135). Mean VAS score and utility values were lower for females with HPV-related diseases than those without (72.18 vs 76.86 and 0.90 vs 0.94, respectively).ConclusionIn South Korea, GW in men and HPV-related diseases in women negatively impact patient well-being and HRQoL scores. Among women, those with GW suffered a greater psychosocial impact than those with other selected HPV-related diseases.

Project description:BackgroundGenital warts (GW) are the most common sexually transmitted infections. To date, few studies using a human papillomavirus (HPV)-specific questionnaire have focused on the impact of quality of life (QoL) among patients with GW in developing countries. The origins of GW related psychosocial burdens and variations between genders were poorly characterized as well.MethodsA hospital-based survey was conducted in Beijing and Nanjing of China in 2008. Eligible patients aged 18-65 who had a diagnosis of GW within 3 months were recruited. Demographic information, HPV knowledge, and assessment of psychosocial burden were collected by the HPV Impact Profile (HIP). The HIP examined 7 specific psychosocial domains by 29 items: (1) worries and concerns, (2) emotional impact, (3) sexual impact, (4) self-image, (5) partner and transmission, (6) interactions with physicians, and (7) control/life impact. HIP scores are reversely relates to the subjects' QoL, by which a higher score indicating a heavier psychosocial burden.ResultsPatients with GW experienced heavier psychosocial burdens than those of the general population, and females experienced heavier burdens than males (male vs. female: 49.20 vs.51.38, P?<?0.001). "Self Image" and "Sexual Impact" were the two domains that affected patients the most, with mean HIP scores of 63.09 and 61.64, respectively. Women suffered heavier psychosocial burdens than men in the domain of "Worries and Concerns" (female vs. male: 54.57 vs. 42.62, P?<?0.001), but lower psychosocial burdens in the domains of "Sexual Impact" (female vs. male: 59.16 vs. 65.26, P?<?0.001) and "Interactions with Doctors" (female vs. male: 34.40 vs. 41.97, P?<?0.001). Patients from Nanjing suffered a higher psychosocial burden than those of Beijing, especially in domains of "Emotional Impact", "Sexual Impact", "Partner and Transmission", and "Interactions with Doctors".ConclusionsPatients with GW suffered heavy psychological burden, and self-image and sexual-related concern were the primary cause of burdens. It's important to change the current biomedical model to bio-psycho-social model, and establish psychosocial support systems. The distinctions of origins of psychosocial burden between genders identified will be informative for prevention of GW and control efforts in China and other similar settings.

Project description:BackgroundThe recently-observed trend towards younger stroke patients in Korea raises economic concerns, including erosion of the workforce. We compared per-person lifetime costs of stroke according to the age of stroke onset from the Korean societal perspective.MethodsA state-transition Markov model consisted of three health states ('post primary stroke event', 'alive post stroke', and 'dead') was developed to simulate the natural history of stroke. The transition probabilities for fatal and non-fatal recurrent stroke by age and gender and for non-stroke causes of death were derived from the national epidemiologic data of the Korean Health Insurance Review and Assessment Services and data from the Danish Monitoring Trends in Cardiovascular Disease study. We used an incidence-based approach to estimate the long-term costs of stroke. The model captured stroke-related costs including costs within the health sector, patients' out-of-pocket costs outside the health sector, and costs resulting from loss of productivity due to morbidity and premature death using a human capital approach. Average insurance-covered costs occurring within the health sector were estimated from the National Health Insurance claims database. Other costs were estimated based on the national epidemiologic data and literature. All costs are presented in 2008 Korean currency values (Korean won = KRW).ResultsThe lifetime costs of stroke were estimated to be: 200.7, 81.9, and 16.4 million Korean won (1,200 KRW is approximately equal to one US dollar) for men who suffered a first stroke at age 45, 55 and 65 years, respectively, and 75.7, 39.2, and 19.3 million KRW for women at the same age. While stroke occurring among Koreans aged 45 to 64 years accounted for only 30% of the total disease incidence, this age group incurred 75% of the total national lifetime costs of stroke.ConclusionsA higher lifetime burden and increasing incidence of stroke among younger Koreans highlight the need for more effective strategies for the prevention and management of stroke especially for people between 40 and 60 years of ages.

Project description:Background: Substantial declines in genital warts have been observed in countries with quadrivalent/nonavalent human papillomavirus (q/n HPV) vaccination programmes, with Australia showing the most pronounced and long-term reductions. No study has assessed progress towards elimination of genital warts in a nation-wide sample of patients, and migrants' contribution to population-level control of genital warts. We assessed Australia's progress towards genital warts elimination by examining trends in diagnoses in Australian- and overseas-born patients of sexual health clinics (SHCs) across Australia. Methods: A cross-sectional trend analysis of new genital warts diagnoses among first-time patients of 34 SHCs, between 2004 and 2018, was performed. Rate ratios (RR) were calculated using Poisson regression models, for comparing trends in proportions of new genital warts diagnoses in Australian- and overseas-born patients during the pre-vaccination era (2004-2007) and the vaccination era (2008-2018), and by 2018 relative to 2004-2007. Findings: A total of 439,957 new patients (Australian-born: 230,230; overseas-born: 209,727) were seen at SHCs, 6•4% were diagnosed with genital warts (Australian-born: 7•1%; overseas-born: 5•6%). By 2018, there had been a 64% reduction in the proportion of all SHC patients with a genital warts diagnosis relative to 2004-2007 (RR: 0•36, 95% CI: 0•35-0•38). The decline was more pronounced at 72% (RR: 0•28, 95% CI: 0 •27-0•30) among Australian-born patients, with the greatest reduction in women and men aged <21 years, at 98% (RR: 0•02, 95% CI: 0•01-0•03) and 92% (RR: 0•08, 95% CI: 0•06-0•11), respectively. By 2018, there was a 49% reduction in the proportion of overseas-born patients diagnosed with genital warts (RR: 0•51, 95% CI:0•48-0•54), and a 21% reduction in overseas-born patients from countries with no or bivalent HPV (bHPV) vaccination programme (RR: 0•79, 95% CI: 0•71-0•90). Interpretation: The substantial reductions in Australian-born people is a testament to the efficacy of quadrivalent (qHPV) and nonavalent (nHPV) vaccines and the high and wide-spread vaccination coverage in Australia. However, population-wide elimination of genital warts in Australia is dependent on other countries initiating or expanding their own HPV vaccination programmes.
