Non-surgical adult male circumcision using the PrePex device: task-shifting from physicians to nurses.

The Republic of Rwanda is implementing a program of voluntary male circumcision (MC) to reduce HIV transmission but lacks the infrastructure for conventional surgical MC on a nationwide scale. Nonsurgical MC using the PrePex device was first assessed in 5 subjects on an inpatient basis. Subsequent procedures were on an outpatient basis. Physicians performed 100 outpatient procedures (Phase 1 of this study) and trained nurses in the technique; the nurses then independently performed 47 procedures (Phase 2). All subjects achieved complete circumcision and healing within 6 weeks. There were no cases of infection or bleeding. In Phase 1, one case of transient moderate diffuse edema occurred. In Phase 2, no adverse events were reported. Thus, outcomes of MC performed by nurses using the PrePex device were not inferior to outcomes achieved by physicians, suggesting that task-shifting MC by this method from physicians to nurses is feasible in Rwanda.

Cost Analysis of Adult Male Circumcision with the PrePex Device versus Surgery in Rwanda.

In this study from Rwanda, voluntary adult male circumcision costs 33% less with trained nurses using the PrePex device compared with physician-nurse teams performing dorsal-slit surgery. These cost savings and the documented safety, speed, and efficacy of the PrePex procedure, serve Rwanda's HIV prevention program.

Assessing Odor Level when Using PrePex for HIV Prevention: A Prospective, Randomized, Open Label, Blinded Assessor Trial to Improve Uptake of Male Circumcision.

The PrePex is a WHO--prequalified medical device for adult male circumcision for HIV prevention. The Government of Rwanda was the first country to implement the PrePex device and acts as the leading center of excellence providing training and formal guidelines. As part of the Government's efforts to improve PrePex implementation, it made efforts to improve the psychological acceptability of device by men, thus increasing uptake with VMMC in sub-Saharan Africa. Some men who underwent the PrePex procedure complained of foreskin odor while wearing the PrePex 3-7 days after it was placed. This complaint was identified as potential risk for uptake of the device. Researchers from Rwanda assumed there is a possible relation between the level of foreskin odor and patient foreskin hygiene technique. The Government of Rwanda decided to investigate those assumptions in a scientific way and conduct a trial to test different hygiene-cleaning methods in order to increase the acceptability of PrePex and mitigate the odor concern. The main objective of the trial was to compare odor levels between three arms, having identical personal hygiene but different foreskin hygiene techniques using either clear water with soap during a daily shower, soapy water using a syringe, or chlorhexidine using a syringe. One hundred and one subjects were enrolled to the trial and randomly allocated into three trial arms. Using chlorhexidine solution daily almost completely eliminated odor, and was statistically significant more effective that the other two arms. The trial results suggest that odor from the foreskin, while wearing the PrePex device, could be related to the growth of anaerobic bacteria, which can be prevented by a chlorhexidine cleaning method. This finding can be used to increase acceptability by men when considering PrePex as one of the leading methods for HIV prevention in VMMC programs.

Occupational health and gorilla conservation in Rwanda.

The design and implementation of an employee health program for people who work with mountain gorillas in Rwanda is described. This program aims to improve worker health and to reduce human-to-gorilla transmission of infectious disease. The program covered approximately 111 workers, generally healthy men and women 25-45 years old, including essentially all people in Rwanda who have regular contact with gorillas. Initial assessment included a questionnaire, medical examination, and local tests. U.S. laboratory facilities were utilized to confirm some results and for serologic testing for zoonotic (simian) viruses. Initial interventions included STD/HIV prevention health education, tetanus immunization, and anthelminthic treatment. Local physicians continue to provide health services, including follow-up testing and treatment. Mountain Gorilla Veterinary Project (MGVP) veterinarians assist in planning and implementing continuing program components in collaboration with local health authorities and the other employing organizations.
