RESUMO

Introduction: Anemia remains a prevalent global health issue with varying severity. Intravenous iron supplementation, particularly with ferric carboxymaltose (FCM), has appeared as a possible therapeutic intervention for individuals with moderate to severe anemia. The study aimed to assess the efficacy and safety of ferric carboxymaltose (FCM) in reducing anemia. Methods: We searched electronic databases, registries, websites, e-libraries, reference lists of reviews, citations, etc. We included randomized control trials (RCTs), non-RCTs, and single-arm studies, while observational studies, case series, and case studies were excluded. Two reviewers independently screened the studies and extracted the data. We included studies of moderate-to-severely anemic Indians and excluded Indians with other comorbidities. We assessed the risk of bias and the overall quality of evidence (QoE) using GRADE GDT. Result: We identified 255 studies and included 14 studies (11 RCT, one non-RCT, and two single-arm studies) with 1,972 participants for qualitative analysis and 10 studies in the meta-analysis. All the included studies detailed the use of FCM for anemia. The primary outcomes assessed in the included studies were anemia, hemoglobin, and adverse events. The outcomes assessed ranged from 2 weeks to 12 weeks. The risk of bias varied across different studies with different outcomes. FCM is consistent with a fewer number of adverse events as compared to other interventions and provides "moderate" to "very low" QoE. Conclusion: A slow single infusion of 1 gram of FCM is well-tolerated, safe, and effective in treating iron deficiency anemia (IDA) and surpasses other interventions (Iron Sucrose Complex (ISC), Iron sucrose, and ferrous ascorbate) in elevating hemoglobin levels and replenishing iron stores.

RESUMO

Background: Optimal breastfeeding (BF) practices are essential for child survival and proper growth and development. The purpose of this overview is to evaluate the effectiveness of different interventions for promoting and optimizing breastfeeding. Methods: We included systematic reviews (SRs) [including trials from Low-Income (LICs) and Low Middle-Income countries (LMICs)] that have evaluated the effect of various interventions for promoting and optimizing breastfeeding and excluded non-systematic reviews, and SRs based on observational studies. We searched various electronic databases. We followed the standard methodology as suggested by the Cochrane Handbook for Systematic Reviews of Interventions. Two sets of reviewers undertook screening followed by data extraction and assessment of the methodological quality of included SRs. Result: We identified and screened 1,002 Cochrane SRs and included six SRs in this overview. Included SRs reported only two of the primary outcomes, early initiation of breastfeeding (EIBF) and/or exclusive breastfeeding (EBF). None of the included SR reported continued BF up to 2 years of age. The results were evaluated using two major comparisons groups: BF intervention against routine care and one type of BF intervention vs. other types of BF intervention. Overall results from included SRs showed that there were improvements in the rates of EIBF and EBF among women who received BF intervention such as BF education sessions and support compared to those women who received only standard care. However, BF intervention via mobile devices showed no improvements. In Target Client Communication (TCC) via mobile devices intervention group, no significant improvements were reported in BF practices, and also the reported evidence was of very low certainty. Conclusion: Community Based Intervention Packages (CBIP) delivered to pregnant and reproductive-age women during their Antenatal care (ANC) and/or Postnatal care (PNC) periods by Ancillary Nurse-Midwives reported the highest improvement in EIBF compared to women who received standard care. However, insufficient evidence was reported to suggest that BF intervention showed improvements in EBF in both the comparison groups. This overview highlighted the gaps in primary research regarding the uncertainty about the settings such as LICs or LMICs, lack of evidence from LMICs, and also identified gaps in the availability of reliable up-to-date SRs on the effects of several BF interventions to promote and optimize practices.

RESUMO

Background: Preventive public health has been suggested as methods for reducing the transmission of COVID-19. Safety and efficacy of one such public health measure: WASH intervention for COVID-19 has not been systematically reviewed. We undertook a rapid review to assess the effect of WASH intervention in reducing the incidence of COVID-19. Methods: We conducted searches in PubMed, MEDLINE, and EMBASE. We undertook screening of studies in two stages and extracted data and assessed the quality of evidence for the primary outcome using GRADE recommendations. Main results: We included a total of 13 studies with three studies on COVID-19 and 10 on SARS. The study found that hand washing, sterilization of hands, gargling, cleaning/shower after attending patients of COVID-19, or SARS was protective. Evidence also found that frequent washes can prevent SARS transmission among HCWs. However; one study reported that due to enhanced infection-prevention measures, front-line HCWs are more prone to hand-skin damage. The certainty of the evidence for our primary outcome as per GRADE was very low. We did not find any studies that assessed the effect of WASH on hospitalizations, and mortality due to COVID-19. Also; we did not find any study that compared WASH interventions with any other public health measures. Conclusions: Current evidence of WASH interventions for COVID-19 is limited as it is largely based on indirect evidence from SARS. Findings from the included studies consistently show that WASH is important in reducing the number of cases during a pandemic. Timely implementation of WASH along with other public health interventions can be vital to ensure the desired success. Further good-quality studies providing direct evidence of the efficacy of WASH on COVID-19 are needed.

RESUMO

Wild reservoirs of Japanese encephalitis virus are under-studied globally, which presents critical knowledge gaps for JEV epidemiology and infection ecology despite decades of received wisdom regarding this high-impact mosquito-borne virus. As a result, ardeid birds, generally understood to be the primary reservoirs for JEV, as well as other waterbirds occupying landscapes at high risk for spillover to humans, are frequently ignored by current surveillance mechanisms and infrastructure. This is particularly true in India, which experiences a high annual burden of human outbreaks. Incorporating wild reservoirs into surveillance of human and livestock populations is therefore essential but will first require a data-driven approach to target individual host species. The current study sought to identify preliminary waterbird target species for JEV surveillance development based on species' distributions in high-risk landscapes. Twenty-one target species were identified after adjusting species presence and abundance for the biotic constraints of sympatry. Furthermore, ardeid bird species richness demonstrated a strong non-linear association with the distribution of human JEV outbreaks, which suggested areas with the highest ardeid species richness corresponded to low JEV outbreak risk. No association was identified between JEV outbreaks and anatid or rallid richness. The lack of association between Anatidae and Rallidae family-level diversity and JEV outbreak risk notwithstanding, this study did identify several individual species among these two bird families in high-risk landscapes. The findings from this work provide the first data-driven evidence base to inform wildlife sampling for the monitoring of JEV circulation in outbreak hotspots in India and thus identify good preliminary targets for the development of One Health JEV surveillance.

RESUMO

BACKGROUND: Japanese encephalitis virus (JEV) is a zoonotic mosquito-borne virus that causes a significant burden of disease across Asia, particularly in India, with high mortality in children. JEV circulates in wild ardeid birds and domestic pig reservoirs, both of which generate sufficiently high viraemias to infect vector mosquitoes, which can then subsequently infect humans. The landscapes of these hosts, particularly in the context of anthropogenic ecotones and resulting wildlife-livestock interfaces, are poorly understood and thus significant knowledge gaps in the epidemiology of JEV persist. This study sought to investigate the landscape epidemiology of JEV outbreaks in India over the period 2010-2020 to determine the influence of shared wetland and rain-fed agricultural landscapes and animal hosts on outbreak risk. METHODS: Using surveillance data from India's National Centre for Disease Control Integrated Disease Surveillance Programme, JEV outbreaks were modelled as an inhomogeneous Poisson point process and externally validated against independently sourced data. RESULTS: Outbreak risk was strongly associated with the habitat suitability of ardeid birds, both pig and chicken density, and the shared landscapes between fragmented rain-fed agriculture and both river and freshwater marsh wetlands. CONCLUSION: The results from this work provide the most complete understanding of the landscape epidemiology of JEV in India to date and suggest important One Health priorities for control and prevention across fragmented terrain comprising a wildlife-livestock interface that favours spillover to humans.

RESUMO

Kyasanur forest disease virus (KFDV) is a rapidly expanding tick-borne zoonotic virus with natural foci in the forested region of the Western Ghats of South India. The Western Ghats is one of the world's most important biodiversity hotspots and, like many such areas of high biodiversity, is under significant pressure from anthropogenic landscape change. The current study sought to quantify mammalian species richness using ensemble models of the distributions of a sample of species extant in the Western Ghats and to explore its association with KFDV outbreaks, as well as the modifying effects of deforestation on this association. Species richness was quantified as a composite of individual species' distributions, as derived from ensembles of boosted regression tree, random forest, and generalised additive models. Species richness was further adjusted for the potential biotic constraints of sympatric species. Both species richness and forest loss demonstrated strong positive associations with KFDV outbreaks, however forest loss substantially modified the association between species richness and outbreaks. High species richness was associated with increased KFDV risk but only in areas of low forest loss. In contrast, lower species richness was associated with increased KFDV risk in areas of greater forest loss. This relationship persisted when species richness was adjusted for biotic constraints at the taluk-level. In addition, the taluk-level species abundances of three monkey species (Macaca radiata, Semnopithecus hypoleucus, and Semnopithecus priam) were also associated with outbreaks. These results suggest that increased monitoring of wildlife in areas of significant habitat fragmentation may add considerably to critical knowledge gaps in KFDV epidemiology and infection ecology and should be incorporated into novel One Health surveillance development for the region. In addition, the inclusion of some primate species as sentinels of KFDV circulation into general wildlife surveillance architecture may add further value.

RESUMO

Since the recent introduction of several viable vaccines for SARS-CoV-2, vaccination uptake has become the key factor that will determine our success in containing the COVID-19 pandemic. We argue that game theory and social network models should be used to guide decisions pertaining to vaccination programmes for the best possible results. In the months following the introduction of vaccines, their availability and the human resources needed to run the vaccination programmes have been scarce in many countries. Vaccine hesitancy is also being encountered from some sections of the general public. We emphasize that decision-making under uncertainty and imperfect information, and with only conditionally optimal outcomes, is a unique forte of established game-theoretic modelling. Therefore, we can use this approach to obtain the best framework for modelling and simulating vaccination prioritization and uptake that will be readily available to inform important policy decisions for the optimal control of the COVID-19 pandemic.

RESUMO

BACKGROUND: In TB, therapeutic drug monitoring (TDM) is recommended for linezolid; however, implementation is challenging in endemic settings. Non-invasive saliva sampling using a mobile assay would increase the feasibility of TDM. OBJECTIVES: To validate a linezolid saliva assay using a mobile UV spectrophotometer. METHODS: The saliva assay was developed using NanoPhotometer NP80® and linezolid concentrations were quantified using second-order derivative spectroscopy. Sample preparation involved liquid-liquid extraction of saliva, using saturated sodium chloride and ethyl acetate at 1:1:3 (v/v/v). The assay was validated for accuracy, precision, selectivity, specificity, carry-over, matrix effect, stability and filters. Acceptance criteria were bias and coefficient of variation (CV) <15% for quality control (QC) samples and <20% for the lower limit of quantification (LLOQ). RESULTS: Linezolid concentrations correlated with the amplitude between 250 and 270 nm on the second-order derivative spectra. The linezolid calibration curve was linear over the range of 3.0 to 25 mg/L (R2 = 0.99) and the LLOQ was 3.0 mg/L. Accuracy and precision were demonstrated with bias of -7.5% to 2.7% and CV ≤5.6%. The assay met the criteria for selectivity, matrix effect, carry-over, stability (tested up to 3 days) and use of filters (0.22 µM Millex®-GV and Millex®-GP). Specificity was tested with potential co-medications. Interferences from pyrazinamide, levofloxacin, moxifloxacin, rifampicin, abacavir, acetaminophen and trimethoprim were noted; however, with minimal clinical implications on linezolid dosing. CONCLUSIONS: We validated a UV spectrophotometric assay using non-invasive saliva sampling for linezolid. The next step is to demonstrate clinical feasibility and value to facilitate programmatic implementation of TDM.

RESUMO

INTRODUCTION: Differentiation between relapse and reinfection in cases with tuberculosis (TB) recurrence has important implications for public health, especially in patients with human immunodeficiency virus (HIV) co-infection. We compared Mycobacterial Interspersed Repeat Unit (MIRU) typing and spoligotyping with whole genome sequencing (WGS) to differentiate between relapse and reinfection in patients (HIV-positive and HIV-negative) with TB recurrence. We also assessed the value of WGS to track acquired drug resistance in those with relapse after successful treatment. METHOD: Forty-one paired M. tuberculosis isolates collected from 20 HIV-positive and 21 HIV-negative patients were subjected to WGS in addition to spoligotyping and MIRU typing. Phylogenetic and Single Nucleotide Substitution (SNP) clustering analyses were performed to determine whether recurrences were due to relapse or re-infection. RESULTS: Comparison of M. tuberculosis genomes indicated that 95% of TB recurrences in the HIV-negative cohort were due to relapse, while the majority of TB recurrences (75%) in the HIV-positive cohort was due to reinfection (P = 0.0001). New drug resistance mutations were acquired in 5/24 cases (20.8%) that experienced relapse. CONCLUSIONS: WGS provided increased resolution, but differentiation between relapse and reinfection was broadly consistent with MIRU and spoligotyping. The high contribution of reinfection among HIV infected patients experiencing TB recurrence warrants further study to explore risk factors for TB exposure.

RESUMO

The health and economic impacts of infectious disease pandemics are catastrophic as most recently manifested by coronavirus disease 2019 (COVID-19). The emerging infections that lead to substantive epidemics or pandemics are typically zoonoses that cross species boundaries at vulnerable points of animal-human interface. The sharing of space between wildlife and humans, and their domesticated animals, has dramatically increased in recent decades and is a key driver of pathogen spillover. Increasing animal-human interface has also occurred in concert with both increasing globalisation and failing health systems, resulting in a trifecta with dire implications for human and animal health. Nevertheless, to date we lack a geographical description of this trifecta that can be applied strategically to pandemic prevention. This investigation provides the first geographical quantification of the intersection of animal-human interfaces, poor human health system performance and global connectivity via the network of air travel. In so doing, this work provides a systematic, data-driven approach to classifying spillover hazard based on the distribution of animal-human interfaces while simultaneously identifying globally connected cities that are adjacent to these interfaces and which may facilitate global pathogen dissemination. We present this geography of high-impact spillover as a tool for developing targeted surveillance systems and improved health infrastructure in vulnerable areas that may present conduits for future pandemics.

RESUMO

BACKGROUND: Global health education has attracted significant attention in recent years from academic institutions in developed countries. In India however, a recent analysis found that delivery of global health education is fragmented and called for academic institutions to work towards closing the developing country/developed country dichotomy. Our study explored the understanding of global health in the Indian setting and opportunities for development of a global health education framework in Indian public health institutions. METHODS: The study involved semi-structured interviews with staff of Indian public health institutes and other key stakeholders in global health in India. The interview questions covered participants' interpretation of global health and their opinion about global health education in India. Thematic analysis was conducted. A theoretical framework developed by Smith and Shiffman to explain political priority for global health initiatives was adapted to guide our analysis to explore development of global health education in Indian public health institutions. RESULTS: A total of 17 semi-structured interviews were completed which involved 12 faculty members from five public health institutes and five stakeholders from national and multilateral organisations. Global health was viewed as the application of public health in real-world setting and at a broader, deeper and transnational scale. The understanding of global health was informed by participants' exposure to work experiences and interaction with overseas faculty. Most common view about the relationship between global health and public health was that public health has become more global and both are interconnected. Integration of global health education into public health curriculum was supported but there were concerns given public health was still a new discipline in India. Most participants felt that global health competencies are complementary to public health competencies and build on core public health skills. Employability, faculty exposure to global health and 'sensitisation' of all stakeholders were key barriers to offering global health education programs. CONCLUSION: Global health as a concept and educational practice is embryonic in India but there is considerable potential to grow in order to ensure that education meets the needs of future practitioners of global health in the context of sustainable development.

RESUMO

Background Transmitted human immunodeficiency virus type 1 (HIV-1) drug resistance (TDR) is an important contributor to antiretroviral treatment failure, and is associated with HIV-1 transmission among men who have sex with men (MSM), non-MSM clusters and individuals diagnosed with concurrent sexually transmissible infections (STI). Western Sydney has a culturally diverse population, with a high proportion of non-Australian-born individuals. This study describes the prevalence of TDR and non-B HIV-1 subtypes in a clinic-based population. METHODS: A clinic database was examined for all newly diagnosed treatment-naïve HIV-1 patients and information on their HIV-1 resistance and subtype, demographics including country of birth and diagnosis of a bacterial sexually transmissible infection was collected. RESULTS: Data were available from 74/79 individuals (62 cis-male, 16 cis-female and 1 transgender woman). Of the 74 genotypes, the prevalence of non-B subtypes and TDR was 43/74 (58%; 95%CI = 46.9-69.3) and 14/74 (19%; 95%CI = 10.0 to 27.8). It was also found that 30/79 (38%) had a concurrent bacterial STI. TDR was associated with subtype B infection (OR 3.53; 95%CI = 1.41-8.82; P = 0.007) and being born in Australia (OR 12.0; 95%CI = 2.45-58.86; P = 0.002). CONCLUSION: The relative prevalence of non-B HIV-1 subtypes and TDR is higher in Western Sydney than in the rest of Australia. TDR is associated with subtype B HIV-1 and being Australian born, suggesting ongoing local transmission. This highlights the diversity of the HIV epidemic locally and the need for interventions to prevent ongoing HIV transmission.

RESUMO

Global health discipline is of increasing interest for educators and students in public health across the world. Public health education is recently gaining momentum in India, but global health is still at an embryonic stage. Value of students as stakeholders in curriculum development is increasingly recognized but literature about perspectives of public health students regarding global health education is limited. This study aimed to explore Indian public health students' perspectives about global health education and to provide platform for the development of global health education framework for future public health professionals. This study involved a series of focus groups with students and sought to understand perceptions about global health and global health education framework. We recruited public health students at three institutes across India for focus group discussions. Focus groups questions covered current understanding of global health, opinions regarding global health education for public health curriculum and the relevance of global health competency domains for future employment. Recordings were transcribed verbatim and the transcripts were read along with field notes and then analyzed thematically. A total of 36 students participated in four focus groups. There was a general recognition that global health is transnational and that a global outlook is now essential. But there were concerns regarding local and global priorities in public health. Global health was regarded as being wider than public health by some, but others viewed public health being the umbrella term with global health as a specialization. Global health competencies were viewed as a "step up" from the public health competencies but core public health competencies were considered essential. International experiences and use of technology were key themes for delivery of global health education. Employability and career progression for global health graduates were of concern for many participants. This study provides insight into the student perspectives regarding global health education for public health programs in India. Clear direction in terms of curriculum and its utility for career growth and employability as a global health professional needs to be established for global health education in India and other similar settings.

RESUMO

INTRODUCTION: Disclosure of HIV status to sexual partners can help HIV prevention efforts and enable HIV positive people to receive social support, as well as increasing access and adherence to treatment. This study was conducted to determine the rate, processes, outcomes, and correlates of HIV status disclosure to sexual partners among HIV positive individuals. METHOD: A cross-sectional study was conducted between September and November 2015 at two HIV outpatient clinics in Addis Ababa, Ethiopia. Data were collected using an interviewer- administered semi-structured questionnaire. Logistic analysis was used to determine the independent correlates of serostatus disclosure. RESULTS: Of 742 participants, (371 men and 371 women), 727 (98%) were on antiretroviral therapy and 676 (91.1%) had at least one sexual partner since their HIV diagnosis, of whom 558 (82.5%) had disclosed their HIV status to their most recent sexual partner. Of those who reported having disclosed their status to their most recent sexual partner, 82 (14.7%) had at least one unprotected sexual encounter with the partner, after HIV diagnosis but prior to disclosure. The most commonly reported initial outcome of disclosure was gaining emotional and/or financial support. Some (11.3%) also reported that their disclosure immediately initiated their partner for HIV testing. Negative outcomes to disclosure, such as stigma and discrimination, were more common among females (26.2%) compared to males (12.7%). In the multiple regression analysis, disclosure was associated with greater condom use, greater social support, knowing the partner's HIV status, having a good relationship with the partner, and cohabiting with the partner. CONCLUSION: HIV disclosure was common amongst participants, although sometimes delayed, with possible consequences for onward transmission. Fear of negative outcomes, such as verbal abuse and physical violence, were major barriers to disclosure. Efforts to support disclosure have the potential to contribute to HIV control and prevention by encouraging safer sexual practice, initiating partners for HIV testing, and enhancing support for people living with HIV.

RESUMO

INTRODUCTION: Rates of new HIV-1 diagnoses are increasing in Australia, with evidence of an increasing proportion of non-B HIV-1 subtypes reflecting a growing impact of migration and travel. The present study aims to define HIV-1 subtype diversity patterns and investigate possible HIV-1 transmission networks within Australia. METHODS: The Australian Molecular Epidemiology Network (AMEN) HIV collaborating sites in Western Australia, South Australia, Victoria, Queensland and western Sydney (New South Wales), provided baseline HIV-1 partial pol sequence, age and gender information for 4,873 patients who had genotypes performed during 2005-2012. HIV-1 phylogenetic analyses utilised MEGA V6, with a stringent classification of transmission pairs or clusters (bootstrap ≥98%, genetic distance ≤1.5% from at least one other sequence in the cluster). RESULTS: HIV-1 subtype B represented 74.5% of the 4,873 sequences (WA 59%, SA 68.4%, w-Syd 73.8%, Vic 75.6%, Qld 82.1%), with similar proportion of transmission pairs and clusters found in the B and non-B cohorts (23% vs 24.5% of sequences, p = 0.3). Significantly more subtype B clusters were comprised of ≥3 sequences compared with non-B clusters (45.0% vs 24.0%, p = 0.021) and significantly more subtype B pairs and clusters were male-only (88% compared to 53% CRF01_AE and 17% subtype C clusters). Factors associated with being in a cluster of any size included; being sequenced in a more recent time period (p<0.001), being younger (p<0.001), being male (p = 0.023) and having a B subtype (p = 0.02). Being in a larger cluster (>3) was associated with being sequenced in a more recent time period (p = 0.05) and being male (p = 0.008). CONCLUSION: This nationwide HIV-1 study of 4,873 patient sequences highlights the increased diversity of HIV-1 subtypes within the Australian epidemic, as well as differences in transmission networks associated with these HIV-1 subtypes. These findings provide epidemiological insights not readily available using standard surveillance methods and can inform the development of effective public health strategies in the current paradigm of HIV prevention in Australia.

RESUMO

During the last decade, the literature about global health has grown exponentially. Academic institutions are also exploring the scope of their public health educational programs to meet the demand for a global health professional. This has become more relevant in the context of the sustainable development goals. There have been attempts to describe global health competencies for specific professional groups. The focus of these competencies has been variable with a variety of different themes being described ranging from globalization and health care, analysis and program management, as well as equity and capacity strengthening. This review aims to describe global health competencies and attempts to distill common competency domains to assist in curriculum development and integration in postgraduate public health education programs. A literature search was conducted using relevant keywords with a focus on public health education. This resulted in identification of 13 articles that described global health competencies. All these articles were published between 2005 and 2015 with six from the USA, two each from Canada and Australia, and one each from UK, Europe, and Americas. A range of methods used to describe competency domains included literature review, interviews with experts and employers, surveys of staff and students, and description or review of an academic program. Eleven competency domains were distilled from the selected articles. These competency domains primarily referred to three main aspects, one that focuses on burden of disease and the determinants of health. A second set focuses on core public health skills including policy development, analysis, and program management. Another set of competency domains could be classified as "soft skills" and includes collaboration, partnering, communication, professionalism, capacity building, and political awareness. This review presents the landscape of defined global health competencies for postgraduate public health education. The discussion about use of "global health," "international health," and "global public health" will continue, and academic institutions need to explore ways to integrate these competencies in postgraduate public health programs. This is critical in the post-MDG era that we prepare global public health workforce for the challenges of improving health of the "global" population in the context of sustainable development goals.

RESUMO

UNLABELLED: Background In Australia, general practitioners (GPs) manage the majority of sexually transmissible infections (STIs). Most STIs are diagnosed and treated by GPs as a result of symptom recognition or risk identification. We aimed to determine how frequently six common STIs were managed by GPs, the characteristics of the GPs and patients, and any changes over time. METHODS: Data from the Bettering the Evaluation and Care of Health (BEACH) program for April 2000-March 2012 were analysed. BEACH is a national study of GP activity. The overall management rates of genital herpes (herpes simplex virus, HSV), genital warts, HIV, chlamydia (Chlamydia trachomatis), gonorrhoea (Neisseria gonorrhoeae) and syphilis were calculated. RESULTS: In total, 11784 GPs recorded details of 1178400 patient encounters. These included: 115 cases of genital HSV per 100000 encounters, 92 of genital warts, 67 of HIV, 39 of chlamydia, 6 of gonorrhoea and 7 of syphilis. Higher management rates occurred among patients who were male, 15-24 years old, more socially advantaged, Aboriginal or Torres Strait Islander, resident in a major city or of English-speaking background. GPs who were female and those aged under 60 years had higher STI management rates than their counterparts. CONCLUSIONS: HSV and warts were the most common STIs managed. Lower management rates for the other STIs may reflect lower incidence or lower testing rates, because these other STIs are frequently asymptomatic. It is important to determine whether existing approaches effectively target the most at-risk communities and what barriers to presentation exist.

RESUMO

OBJECTIVE: To determine the characteristics of general practitioners (GPs) who test and patients who are tested for HIV in Australia. DESIGN AND SETTING: A secondary analysis of data from the Bettering the Evaluation and Care of Health programme; a cross-sectional, national survey of GP activity. METHODS: We identified GP, patient and encounter characteristics that were associated with HIV testing between April 2000 and March 2010. We looked at testing rates for patients with different characteristics, whether they had attended for screening and GP 'risk factor' identification. Multiple logistic regression was used to measure the independent effect of each GP, patient and encounter characteristic on testing for HIV. RESULTS: Data were available for 984,200 encounters from 9842 GPs. 1796 (18.2%) of GPs performed at least one HIV test. On logistic regression, independent predictors of HIV testing included the management of a 'risk factor' (OR 19.4, 95% CI 17.4 to 21.6), screening (OR 10.6, 95% CI 9.4 to 12.1), younger GP age, practice in a metropolitan area (OR 1.4, 95% CI 1.2 to 1.6), patient age, gender (male > female OR 3.0, 95% CI 2.7 to 3.3), being new to that practice (OR 2.1, 95% CI 1.8 to 2.3) and being Indigenous (OR 1.7, 95% CI 1.3 to 2.4). CONCLUSION: The most significant independent predictors of testing were identification of a risk factor and attendance for screening. Unless barriers to testing are addressed it is unlikely that altering guidelines alone will improve testing rates and reduce transmission.
