Cases will be identified at Mae Tao Clinic by local staff.  The local staff and the BCMF Program Manager will assess children that need special medical procedures. The BCMF Medical Advisor will also be consulted for difficult cases and to assess the prospects of a patient. A decision will be made as to whether a child will be referred to a major hospital for treatment taking into consideration many factors, such as cost/availability of resources, chances of survival without treatment, expected improvement in the quality of life, and overall prognosis.  Cases with the greatest likelihood of being corrected with a single surgery will be given priority.
