Hepatitis C incidence among patients attending primary care health services that specialise in the care of people who inject drugs, Victoria, Australia, 2009 to 2020.

BACKGROUND: Monitoring trends in hepatitis C virus (HCV) incidence is critical for evaluating strategies aimed at eliminating HCV as a public health threat. We estimate HCV incidence and assess trends in incidence over time among primary care patients. METHODS: Data were routinely extracted, linked electronic medical records from 12 primary care health services. Patients included were aged ≥16 years, tested HCV antibody negative on their first test recorded and had at least one subsequent HCV antibody or RNA test (January 2009-December 2020). HCV incident infections were defined as a positive HCV antibody or RNA test. A generalised linear model assessed the association between HCV incidence and calendar year. RESULTS: In total, 6711 patients contributed 17,098 HCV test records, 210 incident HCV infections and 19,566 person-years; incidence was 1.1 per 100 person-years (95% confidence interval (CI): 0.9 to 1.2). Among 559 (8.2%) patients ever prescribed opioid-related pharmacotherapy (ORP) during the observation period, 135 infections occurred during 2,082 person-years (incidence rate of 6.5 per 100 person-years (95% CI: 5.4 to 7.7)). HCV incidence declined 2009-2020 overall (incidence rate ratio per calendar year 0.8 (95% CI: 0.8 to 0.9) and among patients ever prescribed ORT (incidence rate ratio per calendar year 0.9, 95% CI: 0.75 to 1.0). CONCLUSION: HCV incidence declined among patients at primary care health services including among patients ever prescribed ORP and during the period following increased access to DAA therapy.

Comparing sexual behaviours and knowledge between domestic students and Chinese international students in Australia: findings from two cross-sectional studies.

Few studies investigate sexual health among Chinese international students in Australia. We recruited domestic (n = 623) and Chinese international (n = 500) students for separate online surveys on sexual behaviours and knowledge. Samples were compared using Chi square, Fisher's exact and equality of medians tests. Domestic students were more likely than international students to have ever touched a partner's genitals (81% vs. 53%, p < 0.01), had oral sex (76% vs. 44%, p < 0.01), vaginal intercourse (67% vs. 41%, p < 0.01) and anal intercourse (31% vs. 6%, p < 0.01). Domestic students were younger when they first touched a partner's genitals (16 vs. 18 years, p < 0.01), had oral sex (17 vs. 18 years, p < 0.01) and vaginal intercourse (17 vs. 18 years, p < 0.01). Domestic students were less likely than Chinese international students to report only one lifetime partner for touching genitals (22% vs. 50%, p < 0.01), oral sex (25% vs. 55%, p < 0.01), vaginal intercourse (30% vs. 58%, p < 0.01) and anal intercourse (54% vs. 88%, p < 0.01). Domestic students were more likely than Chinese international students to use the oral contraceptive pill (48% vs. 16%, p < 0.01) and long-acting reversible contraceptives (19% vs. 1%, p < 0.01). Domestic students scored higher than international students on a contraception and chlamydia quiz (4/5 vs. 2/5, p < 0.01). Domestic and Chinese international students differed in sexual behaviours and knowledge highlighting the need for relevant sexual health promotion for both groups.

Two decades of surveillance data show late presentation among a diverse group of women diagnosed with HIV in Victoria, Australia.

OBJECTIVE: To develop an HIV response suited to women and to inform appropriate services, we describe the characteristics of women diagnosed and living with HIV using 22 years of high-quality surveillance data. METHODS: Data on women newly diagnosed with HIV between 1994 and 2016 and women living with diagnosed HIV in Victoria at 31 December 2016 were extracted from the Victorian Public Health Surveillance System. Descriptive analysis by place of birth was performed and Poisson regression used to assess trends over time. RESULTS: There were 465 new diagnoses among women in Victoria between 1994 and 2016 and 613 women living with HIV in 2016. Women were diagnosed late, and frequently reported no HIV testing history, AIDS-defining illness or other symptoms of HIV at diagnosis. These indicators of delayed diagnosis were even greater for non-Australian-born women. Conclusions and implications for public health: For Victoria to reach the ambitious targets for diagnosis, treatment and viral suppression in 95% of people living with HIV, prevention programs and efforts to increase early diagnosis as well as support services must consider the epidemiology and diversity of women.

Paying the price in an era of HIV treatment as prevention: a retrospective study of the cost burden of HIV treatment for people living with HIV in Victoria, Australia.

UNLABELLED: Background An estimated 25700 people live with diagnosed HIV (PLWH) in Australia and ~1200 newly diagnosed cases were notified in 2012. New HIV prevention strategies focus on individual uptake of treatment; however, a potential barrier is the financial burden of antiretroviral treatment (ART). We describe HIV ART dispensed and the estimated associated costs for PLWH in Victoria. METHODS: A retrospective cross-sectional study of pharmacy data on ART dispensed between January 2012 and November 2013 from a hospital network, including Victoria's largest sexual health clinic was conducted. Estimated annual patient costs of ART were calculated by the number of items dispensed per year, concession status, dispensing site and applicable co-payment. RESULTS: A total of 60225 dispensing records from 3903 individuals were included; this represented 83.8% of pharmaceutical benefits scheme-recorded ART dispensed in Victoria over this period. The estimated annual co-payment costs for patients without a concession card and who were collecting two medications was $433.20. One-fifth of patients (21.3%) collected four or more items, equating to an estimated annual cost of at least $866.40 without a concession card and $141.60 with a concession card. Of those dispensed four or more items, 40.4% were concession card holders. CONCLUSIONS: There may be meaningful patient costs associated with accessing ART for some PLWH. New HIV treatment-based prevention strategies need to consider financial vulnerabilities and appropriately targeted initiatives to alleviate patient costs associated with ART, ensuring they do not act as a barrier to commencement of and adherence to HIV treatment.

Prevalence survey of dermatological conditions in mountainous north India.

BACKGROUND: Dermatological conditions account for a substantial proportion of the global burden of disease in low and middle income countries (Bickers D, Lim H, Margolis D, et al. The burden of skin diseases: 2004. A joint project of the American Academy of Dermatology Association and the Society for Investigative Dermatology. J Am Acad Dermatol 2006; 55: 490-500) and place major pressures on primary healthcare centers (Satimia F, McBride S, Leppard B. Prevalence of skin disease in rural Tanzania and factors influencing the choice of health care, modern or traditional. Arch Dermatol 1998; 134: 1363-1366). In mountainous North India, where limited resources are available for skin care, no dermatological data exists on prevalence, treatment patterns, or associations. The study aimed to measure prevalence and treatment of dermatological conditions and associated factors in Uttarakhand so to inform delivery of dermatological care and prevention programs in India. METHODS: Single stage cluster randomized sampling generated seven cluster units or villages. Household members (n = 1275) from each cluster were interviewed, and where possible, examined and offered treatment. RESULTS: Dermatological conditions were prevalent (45.3%), with 33% being of infectious etiology. Atopic dermatitis (9.2%), scabies (4.4%), tinea corporis (4.1%), and pityriasis alba (3.6%) were most prevalent. Multivariate analysis showed that cohabitation with animals (OR = 1.62, 95% CI-1.35, 1.95) was a predictor of any skin diseases. A health practitioner was not consulted in 64.7% of dermatological conditions, and where consulted, approximately 69% received inappropriate or ineffective treatments. Excessive spending on dermatological care was commonplace. Limitations associated with cross-sectional cluster methodology included the underrepresentation of seasonal conditions and conditions of short duration. Caste proved difficult to randomize across clusters given villages were often composed according to caste. CONCLUSION: These results demonstrate a high prevalence of dermatological conditions and a pattern of conditions somewhat distinctive to this mountainous area of North India. These findings will assist development of appropriate and cost-effective dermatological services in these mountainous regions.
