Health Volunteers Overseas

ASH partners with Health Volunteers Overseas (HVO), a nonprofit organization dedicated to improving global health through education, to bring invaluable consultation and training to hospitals in the developing world. Training provided by ASH members takes the form of rounds in the clinics, bedside consultations, classroom lectures, training in laboratories, and more. The objective is to develop sustainable improvement in the management of hematology patients at these institutions.

Each program has an ASH member program director and on-site coordinators who oversee volunteer visits at the institutions and provide feedback on their evolving needs and goals. Additionally, onsite hematology, laboratory scientists, blood bankers, faculty, administrators, and others work with ASH and HVO consultants to formulate the mid and long term goals of each site and create profiles for volunteer hematologists who can help fulfill these needs.

Assignments spanning one- to four-weeks are available for pediatric or adult hematology/oncology clinicians, laboratory scientists, and academicians.

How to Apply

To be considered, applicants must be members of both ASH and HVO. Volunteers from outside the United States are encouraged to apply. For more information on the sites, complete the online form, or contact:

Management of a large cohort of patients with acute lymphocytic leukemia (ALL) is a high priority for this volunteer site in Arequipa, Peru. The Catholic University of Santa Maria and affiliated Carlos Alberto Seguin Escobedo Hospital enthusiastically receive ASH volunteers to help address this disease burden, as well as other lymphomas and aplastic anemia. In addition, training in the interpretation of blood smears and bone marrow aspirates, flow cytometry, blood banking, and hematopathology is highly desired. Volunteers are needed for short-term assignments to provide didactic instruction, training and consultations in the clinics, laboratories, blood bank, mentorship, and the modification or preparation of teaching materials.

Current needs and goals at this site include:

  • Adult and pediatric patient management for ALL
  • Performance and interpretation of smear and bone marrow aspirates
  • Development of assessment processes for hematology students, residents, and clinicians
  • Development of protocols and treatment guidelines for blood banking and transfusion medicine
  • Development of protocols and treatment guidelines for benign and malignant hematology

Hematopathologists are particularly desired at Muhimbili National Hospital (MNH) in Dar es Salaam, which is currently experiencing a great need for training in smear review and interpretation of morphology in both peripheral smears and bone marrow aspirates. Blood banking and transfusion medicine experts are also desired at this site on a recurring basis. Sickle cell experts, laboratory scientists, and blood banking and transfusion medicine volunteers are needed as well. Six hematologists work diligently at MNH to manage a large population of hematology patients, but the expertise of ASH members can make an indelible impact toward progress here in the clinics, laboratory, on-site blood bank, and classrooms. The hospital is affiliated with the adjacent Muhimbili University for Health and Allied Sciences (MUHAS), where volunteers are also asked to provide lectures to supplement the hematology curriculum.

This program seeks to improve training in hematology for clinicians, laboratory technicians, technologists, and students at the Mulago Hospital in Kampala. Volunteers provide training in diagnosis, bone marrow and blood smear interpretations, pediatric and adult hematology, and hematologic oncology. This program also works to provide an interface between the laboratory staff and the clinical staff in the interpretation and diagnosis of blood-related illnesses. Volunteers should have a current medical license and be board-certified/eligible in hematology and/or oncology. Previous international travel and/or work experience is preferred. Assignments are from 2 to 4 weeks.

Current needs and goals at this site include:

  • Performance and interpretation of smear and bone marrow aspirates
  • Delivery of standard hematological workups
  • Teaching of techniques (bone marrow biopsy)
  • Performance and interpretation of smears and staining

At Angkor Hospital for Children (AHC) in Siem Reap, hematology volunteers with expertise in clinical laboratory hematology assist in optimizing the functioning of the laboratory, using a systems-based approach. Pediatric hematologists/oncologists with experience running a lab are specifically recruited to work toward this goal. Pediatric hematologists/oncologists provide lectures on benign hematology and pediatric oncology to trainee physicians at AHC, where they also help staff implement treatment for patients with leukemia. Volunteers are needed at specific times to provide training as part of the hematology module offered to pediatric residents. Assignments range 2 to 4 weeks.

Current needs and goals at this site include:

  • Diagnosis and management of ALL
  • Smear interpretation
  • Develop trigger values for low counts (high prevelance of aplastic anemia)
  • Limited bedside training with in-patient department, in-patient rounds on specific presentations
