The authors describe and critically evaluate the existing indicators and propose studies to validate them.

Several indicators have been developed to measure governments' political commitment to respond to national HIV epidemics—the AIDS Program Effort Index, the United Nations General Assembly Special Session on HIV/AIDS Declaration of Commitment Indicators and the AIDS Policy Aggressiveness Indicators—but the validity of these measures has not been systematically assessed. The indicators differ in their intended use, collection methods, content categories, data coverage, and strengths and limitations. Several types of studies could be used to test indicator validity (based on indicator content, comparisons of the same indicator using different elicitation methods, relationship patterns between indicators, relations between indicators and other variables and the consequences of using the indicators).

The existing indicators of political commitment to respond to national HIV epidemics are useful for many purposes, including research, policymaking and advocacy. A range of studies could improve the understanding of indicator validity. New data collection and measurement approaches offer opportunities to improve how actors in the HIV community capture the complicated, multidimensional concept of political commitment.

The authors examine the effect of the shift in intervention strategy on (1) outcome measurement, (2) cost measurement, (3) study-design options and the (4) technical and (5) political feasibility of programme evaluation.

As intervention structure changes from vertical to horizontal, outcome and cost measurements are likely to become more difficult (because the number of relevant outcomes and costs increases and the sources holding data on these measures become more diverse); study-design options become more limited (because it is often impossible to identify a rigorously defined counterfactual in horizontal interventions); the technical feasibility of interventions is reduced (because lag times between intervention and impact increase in length and effect-mediating and -modifying factors increase in number) and political feasibility of evaluation is decreased (because national policymakers may be reluctant to support the evaluation).

In the choice of intervention strategy, policymakers need to consider the effect of intervention strategy on impact evaluation. Methodological studies are needed to identify the best approaches to evaluate the population health impact of horizontal interventions.

Official development assistance for health, HIV programmes and non-HIV programmes were tracked using data from 2000 to 2009. A review of the literature on efficiency, treatment and health systems was conducted.

The rate of growth of donor funding to HIV programmes has slowed in recent years at levels below those required to sustain programmes and to move towards universal access to treatment. These trends are likely due to increased pressure on foreign aid budgets and donor fatigue for HIV programmes.

There is great need to consider how the limited resources available can be used most efficiently to increase the number of lives saved and to ensure that these resources also benefit health systems. Improving efficiency is much more than just improving the productive efficiency and also about ensuring that resources are going to where they will be the most beneficial and making investments that are the most efficient over time. These choices may be essential to achieving the goal of universal access to treatment as well as the sustainability of these programmes.

Systematic literature review. Search of electronic databases, manual searching and snowball sampling. Studies that presented results on cost, efficiency or cost-effectiveness of integrated HIV services were included, focusing on low- and middle-income countries. Evidence was analysed and synthesised through a narrative approach and the quality of studies assessed.

Of 666 citations retrieved, 46 were included (35 peer reviewed and 11 from grey literature). A range of integrated HIV services were found to be cost-effective compared with ‘do-nothing’ alternatives, including HIV services integrated into sexual and reproductive health services, integrated tuberculosis/HIV services and HIV services integrated into primary healthcare. The cost of integrated HIV counselling and testing is likely to be lower than that of stand-alone counselling and testing provision; however, evidence is limited on the comparative costs of other services, particularly HIV care and treatment. There is also little known about the most efficient model of integration, the efficiency gain from integration beyond the service level and any economic benefit to HIV service users.

In the context of increasing political commitment and previous reviews suggesting a strong public health argument for the integration of HIV services, the authors found the evidence on efficiency broadly supports further efforts to integrate HIV services. However, key evidence gaps remain, and there is an urgent need for further research in this area.

To describe HIV care in the USA in 2011 and to consider future trends.

Literature review.

Though evidence for effectiveness of HIV care teams is increasing, HIV care in the USA in 2011 is severely challenged. Low reimbursements, rising caseloads and increasing care complexity are leading to clinician shortages. Access to antiretrovirals through Medicare and Medicaid is worsening, and deficiencies in AIDS Drug Assistance Programs are increasing. Durable health insurance will become available for most Americans in 2014 through new health reforms, but the likelihood of incomplete coverage, fierce political opposition and the uncertain details are reasons for concern. At the same time, recent trends in HIV epidemiology, pathogenesis and care services have reinforced the need for multidisciplinary teams with strong community linkages.

HIV advocates have their greatest challenge to date to ensure that the gains and lessons in HIV care learnt from the past are not lost in the transition to national health reform in the next turbulent 5 years in the USA.

To describe how collaboration in antiretroviral procurement in 2011/2012 aimed to significantly reduce drug acquisition costs, ensure equity of prescribing and protect the quality and experience of care and treatment for patients.

Greater clinical leadership and engagement and involvement of patient representatives enabled an approach to drug procurement focused on clinical outcomes at a patient and population level while reducing cost. Consensus guidelines for implementation were developed and agreed by all London lead clinicians while people living with HIV produced a patient information leaflet to explain the tender process and outcomes. A planned audit is underway at all services to monitor prescribing changes and outcomes for those on treatment.

HIV clinicians, pharmacists and patient representatives were directly involved in this novel therapeutic tendering approach to antiretroviral drug procurement. Modelling indicates that £8–£10 million savings will be released through the process over 2 years.

Clinically led therapeutic tendering of antiretroviral drugs provides an opportunity to protect quality and improve productivity in HIV. The approach is novel in HIV in the UK, and the emergent learning has implications for quality and cost improvement in HIV spending in the UK and potentially in other countries.

This global assessment explores Chinese systems for detecting and treating those with HIV infection with a particular focus on groups at increased risk of sexually transmitted HIV.

Published literature, grey sources and non-governmental reports were reviewed to describe HIV testing and care systems in China.

HIV testing and care in China involve several parallel health systems and have been largely successful in reaching large numbers of vulnerable individuals. Provider-initiated testing and counselling has been more effective than voluntary counselling and testing programmes for expanding HIV testing efforts in China. Individuals with sexually transmitted HIV infection are underrepresented in the antiretroviral care system compared with other high-risk groups.

Comprehensive HIV testing and care bring together a number of Chinese health systems, but there are still gaps and challenges. Research and programmes focused on HIV testing and care for those with increased sexual risk are needed.

In case studies at two government hospitals, the authors reviewed national reporting guidelines, interviewed nurses and undertook a retrospective analysis of routine hospital data from antenatal care, maternity and HIV services from January 2009 to June 2010. Each woman attending these services was given a unique study number to enable analysis of her recorded use of PMTCT services across different hospital visits. These data were compared with the hospitals' monthly PMTCT reports to the district.

Where a woman made more than one visit, PMTCT drug provision could be reported multiple times for the same woman, and women known to be HIV positive prior to pregnancy were omitted from the denominator of PMTCT coverage calculations. Practices for reporting data on maternal PMTCT prophylaxis provision varied in the two hospitals. According to the study data, using the hospital registers and accounting for multiple visits by the same woman, 642 women were known to have HIV and 412 (64%) were given maternal PMTCT prophylaxis. According to the monthly reports, 430 women were diagnosed as having HIV in pregnancy-related services and 538 (125%) were given maternal PMTCT prophylaxis.

If replicated elsewhere, these reporting practices could lead to overestimation of national PMTCT coverage. Simple yet accurate routine data collection systems are needed to monitor PMTCT coverage accurately and to highlight where changes need to be made so as to ensure that infants are born HIV free.

To examine the effectiveness of shared care models of HIV between primary care and specialty care and how primary care providers can assist in improving the care of people with HIV.

Three databases, PubMed, Medline and EMBase, were searched for relevant terms from studies published in the period from 1996 to 2011. Studies that integrated primary care in HIV management and included highly active antiretroviral therapy (HAART) as part of the treatment modality were included.

Eleven studies that met the inclusion criteria were included in this review. Primary care was found to be at least as effective in HIV counselling, testing and treatment and, to a lesser degree, prevention, when compared with specialty care alone. Screening for HIV at a primary care level was cost-effective, especially in a high HIV prevalence and high-risk community. There were no significant adverse clinical outcomes reported in a primary care approach. Effectiveness of various interventions using a primary care approach was demonstrated in the review, including HAART adherence programmes, home care, the involvement of peer health workers and perinatal use of HAART.

Primary care has an important role in the shared care of the diagnosis and management of people with HIV. Some improvements with current guidelines on the management in primary care of people with HIV in developing countries should be considered.

A thematic analysis was conducted of semistructured interviews carried out in 2010 with 24 professionals holding senior roles in government, non-government and professional organisations that influence Australian HIV care policy.

The strengths of the role of the GP were described as their community setting, collaborative partnership with other medical and health professions, and focus on patient needs. A number of associated challenges were also identified including the different needs of GPs with high and low HIV caseloads, the changing expectations of professional roles in general practice, and barriers to service accessibility for people living with HIV.

While there are many advantages to delivering HIV services in primary care, GPs need flexible models of training and accreditation, support in strengthening relationships with other health and medical professionals, and assistance in achieving service accessibility. Consideration of how to support the GP workforce so that care can be made available in the broadest range of geographical and service settings is also critical if systems of HIV care delivery are to be realistic and cost-effective and meet consumer needs.

The authors developed a model of care using 72 private practitioners in five provinces in urban and rural areas of South Africa with centralised clinical support, training, pharmacy control and data management. The authors describe the programme, its quality control measures and patient outcomes using a cohort analysis.

Between January 2005 and December 2008, 9102 individuals were started on ART, 62% female, median age 34 years, median viral load 50 655 copies/ml and median baseline CD4 count 123 cells/μl. Retention (alive and in care) after 12 months was 63% in the 2005 cohort (646 of 1026) and remained similar in the other calendar years, 58%, 68% and 64% in 2006, 2007 and 2008, respectively. After 36 months, retention was 50% and 41% for those enrolled in 2005 and 2006, respectively. The percentage virally suppressed remained similar at 6 months, 82% vs 84%, 84% and 85% from 2005, 2006, 2007 to 2008, respectively, p=0.66; but improved slightly at 12 months, 78% vs 83%, 83% and 84% from 2005 to 2008, p=0.05. At 36 months, it was 84% and 82% for the 2005 and 2006 cohorts, respectively.

The results show that a well-managed private practitioner model can achieve comparable results to public services, although long-term retention needs further evaluation. This model of ART delivery can be used to expand access to ART in areas where the public sector is unable to meet the demand.

Using a comprehensive framework of access, interviews were conducted with over 1200 ART users to assess barriers along three dimensions: availability, affordability and acceptability. Summary statistics were computed and comparisons of access barriers between sites were explored using multivariate linear and logistic regressions.

While availability access barriers in rural settings were found to be mitigated through a more decentralised model of service provision in one site, affordability barriers were considerably higher in rural versus urban settings. 50% of respondents incurred catastrophic healthcare expenditure and 36% borrowed money to cover these expenses in one rural site. On acceptability, rural users were less likely to report feeling respected by health workers. Stigma was reported to be lowest in the two sites with the most decentralised services and the highest coverage of those in need.

While results suggest inequitable access to ART for rural relative to urban users, nurse-led services offered through primary healthcare facilities mitigated these barriers in one rural site. This is an important finding given current policy emphasis on decentralised and nurse-led ART in South Africa. This study is one of the first to present comprehensive evidence on access barriers to assist in the design of policy solutions.

Following a narrative approach, in-depth interviews were conducted with 20 patients successfully and unsuccessfully (ie, with interruptions) receiving ART in urban Johannesburg and rural Bushbuckridge, using a detailed interview guide structured to illuminate interviewees' life circumstances and contextualise illness and treatment trajectories. Participants were interviewed by trained fieldworkers in their local languages. The translated and transcribed interviews were coded by several team members. Codes were cross-examined and showed good congruence.

All interviewees emphasised the positive aspects of receiving ART, the lifeline and hope it provided by improving health, increasing their ability to live actively and reducing visible signs of (stigmatised) illness. Important factors supporting continuing adherence included social and economic support by individuals, role models and networks as well as positive experiences within the healthcare system and of the treatment itself. The main challenges were linked to patients' difficult life circumstances, especially those related to poverty (eg, transport and food costs) and health system constraints, including perceived lack of compassion and flexibility by healthcare workers.

While there are many challenges for the sustainability of ART on an individual and health system level, this study emphasised the need for a patient-centric focus to continue to provide and increase the number of HIV-positive people receiving this lifeline, receiving hope.
