Scale-up of national antiretroviral therapy programs: progress and challenges in the Asia Pacific region.

BACKGROUND: There has been tremendous scale-up of antiretroviral therapy (ART) services in the Asia Pacific region, which is home to an estimated 4.7 million persons living with HIV/AIDS. We examined treatment scale-up, ART program practices, and clinical outcome data in the nine low-and-middle-income countries that share over 95% of the HIV burden in the region. METHODS: Standardized indicators for ART scale-up and treatment outcomes were examined for Cambodia, China, India, Indonesia, Myanmar, Nepal, Papua New Guinea, Thailand, and Vietnam using data submitted by each country to the WHO/The Joint United Nations Programme on HIV/AIDS (UNAIDS)/UNICEF joint framework tool for monitoring the health sector response to HIV/AIDS. Data on ART program practices were abstracted from National HIV Treatment Guidelines for each country. RESULTS: At the end of 2009, over 700,000 HIV-infected persons were receiving ART in the nine focus countries. Treatment coverage varies widely in the region, ranging from 16 to 93%. All nine countries employ a public health approach to ART services and provide a standardized first-line nonnucleoside reverse transcriptase inhibitor-based regimen. Among patients initiated on first-line ART in these countries, 65-88% remain alive and on treatment 12 months later. Over 50% of mortality occurs in the first 6 months of therapy, and losses to follow-up range from 8 to 16% at 2 years. CONCLUSION: Impressive ART scale-up efforts in the region have resulted in significant improvements in survival among persons receiving therapy. Continued funding support and political commitment will be essential for further expansion of public sector ART services to those in need. To improve treatment outcomes, national programs should focus on earlier identification of persons requiring ART, decentralization of ART services, and the development of stronger healthcare systems to support the provision of a continuum of HIV care.

Process evaluation of a community-based intervention promoting multiple maternal and neonatal care practices in rural Nepal.

BACKGROUND: The challenge of delivering multiple, complex messages to promote maternal and newborn health in the terai region of Nepal was addressed through training Female Community Health Volunteers (FCHVs) to counsel pregnant women and their families using a flipchart and a pictorial booklet that was distributed to clients. The booklet consists of illustrated messages presented on postcard-sized laminated cards that are joined by a ring. Pregnant women were encouraged to discuss booklet content with their families. METHODS: We examined use of the booklet and factors affecting adoption of practices through semi-structured interviews with district and community-level government health personnel, staff from the Nepal Family Health Program, FCHVs, recently delivered women and their husbands and mothers-in-law. RESULTS: The booklet is shared among household members, promotes discussion, and is referred to when questions arise or during emergencies. Booklet cards on danger signs and nutritious foods are particularly well-received. Cards on family planning and certain aspects of birth preparedness generate less interest. Husbands and mothers-in-law control decision-making for maternal and newborn care-seeking and related household-level behaviors. CONCLUSIONS: Interpersonal peer communication through trusted community-level volunteers is an acceptable primary strategy in Nepal for promotion of household-level behaviors. The content and number of messages should be simplified or streamlined before being scaled-up to minimize intervention complexity and redundant communication.

A framework for developing reproductive health policies and programmes in Nepal.

Based on experience in Nepal from 1996-2001, this paper presents a six-element framework to support governments in poor countries in developing and implementing reproductive health programmes. The six elements of the framework are: (i) collaborative planning and programming; (ii) strategic assessment; (iii) policy and strategy development; (iv) guideline and material development; (v) reproductive health programme management; and (vi) policy review. Its implementation calls for collaborative work between policymakers and programme managers at all levels of the health system, external donors and development agencies. Change in Nepal is constrained by poor human and financial resources, extremely difficult geography and strong cultural, religious and social traditions. An informal assessment at district level and below found that information tools, clinical protocols and operational guidelines were highly relevant, though problems with utilisation and motivation were noted. Utilisation of strategy and policy documents and tools was reported to be high at national level, but no causal link can be drawn between instruments in the framework and changes in reproductive health indicators. However, access to the tools described in this article can contribute to improvements in coverage and quality of reproductive health services in the hands of motivated people; improved indicators in family planning use, antenatal care and assisted delivery in Nepal in this period support this view.

Vasectomy effectiveness in Nepal: a retrospective study.

The main purpose of this retrospective, cross-sectional study was to evaluate the effectiveness of vasectomy in an ongoing public sector program in Nepal. We evaluated semen samples from men who had previously had a vasectomy, and asked about the occurrence of pregnancies in the men's partners. In addition, the surgeons who performed the vasectomies completed a questionnaire about their techniques. A two-stage stratified sampling procedure was used to select 1263 men from among over 30,000 men, who had previously undergone a no-scalpel vasectomy, mostly by ligation and excision, in 32 districts between July 1996 and June 1999. Semen samples were preserved and analyzed at a central laboratory. A US andrology laboratory validated the lab results. Twenty-three men (2.3%, 95% confidence interval [CI] 1.1-3.6) had >/=500,000 sperm/mL in their semen. Fifteen of those men reported pregnancies conceived after their vasectomy. In addition, six men with azoospermia reported pregnancies for which conception occurred within 3 months after vasectomy. Eleven men with azoospermia reported pregnancies for which conception occurred more than 3 months after vasectomy. Reported pregnancy was more likely in younger partners. The life table pregnancy rates for all men interviewed were 0.7 (95% CI 0.2-1.1), 1.7 (95% CI 1.4-2.1) and 4.2% (95% CI 3.2-5.2) at 3, 12 and 36 months, respectively. In low-resource, programmatic settings, vasectomy failure rates may be higher than commonly cited rates, especially in younger populations. Additional research is needed to determine if other occlusion techniques could reduce failure rates. Counseling on vasectomy should always convey the possibility of failure and partner pregnancy.
