Brief Summary

The purpose of the study is to compare the safety, effectiveness, and acceptability of medical abortion provided by doctors and midlevel providers in a developing country where doctors are scarce, such as Nepal. This study is the first to evaluate the independent provision of medical abortion by trained nurses and auxiliary nurse midwives compared to doctors by assessing differences in safety, clinical outcomes, case management decision-making, and acceptability. This study provides scientifically valid data on the administration of medical abortion by midlevel providers working independently in a low-resource, developing country setting. The evidence generated by the study will assist policy makers in developing countries interested in expanding safe abortion services by eliminating the legal requirement limiting prescription of medical abortion to doctors where medical abortion is not restricted by law.

Detailed Description

Each year, some 210 million women throughout the world become pregnant and nearly one in five chooses to terminate the pregnancy (Singh et al., 2009). Approximately, 22 million pregnancies are terminated unsafely; of these, the vast majority (98%) take place in developing countries (WHO, Forthcoming). Access to safe abortion services is a challenge for many women with unwanted pregnancies in developing countries because of restrictive legislation, a shortage of skilled staff or other barriers.

Non-surgical methods of abortion, known as medical abortion, have been developed that use safe and effective drug-based methods for induced abortion. Prescribing authority is generally limited to doctors, however. As a result, medical abortion remains under-utilized and is often inaccessible for many women in developing countries seeking public sector providers trained in medical abortion in areas where there are no doctors.

Midlevel providers (non-physician clinicians such as nurses and midwives) have the potential to provide accessible, low-cost, and safe abortion services in many countries, especially in the developing world. They are more cost-effective to employ than doctors and often work in areas where doctors are in short supply, providing much needed health services to under-served areas while conserving resources. Training midlevel providers in the independent provision of medical abortion with appropriate referral systems would expand access to safe abortion services to lower levels of the health care system where there is no doctor and complement a global health systems trend towards task-shifting where doctors are costly and scarce (WHO, 2007).

The overall objective of the study is to obtain evidence on the safety and effectiveness of medical abortions performed by government trained and certified midlevel providers and physicians to inform policy makers interested in or committed to expanding and decentralizing medical abortion services.

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: HEALTH_SERVICES_RESEARCH
• Blinding Strategy: NONE

Study Groups

Midlevel provider

Patients were assigned to a midlevel provider (arm 1) or to a physician (arm 2) for their abortion.

Group Type: OTHER

Type of provider

Intervention Type: OTHER

Different types of clinicians have different types of medical training. This study tested whether midlevel providers were as safe and effective in administering medical abortion as doctors. All types of providers underwent the same training in medical abortion and used the same medical abortion regimen.

Physician arm

Patients were assigned to a midlevel provider (arm 1) or to a physician (arm 2) for their abortion.

Group Type: OTHER

Intervention Type: OTHER

Different types of clinicians have different types of medical training. This study tested whether midlevel providers were as safe and effective in administering medical abortion as doctors. All types of providers underwent the same training in medical abortion and used the same medical abortion regimen.
