Results from a horizon scan on risks associated with transplantation of human organs, tissues and cells: from donor to patient.

The successful transplantation of human materials such as organs, tissues and cells into patients does not only depend on the benefits, but also on the mitigation of risks. To gain insight into recent publications on risks associated with the process of transferring human materials from donor to recipient we performed a horizon scan by reviewing scientific literature and news websites of 2011 on this subject. We found there is ample information on how extended donor criteria, such as donor age, affect the survival rates of organs or patients. Interestingly, gender mismatch does not appear to be a major risk factor in organ rejection. Data on risks of donor tumor transmission was very scarce; however, risk categories for various tumor types have been suggested. In order to avoid rejection, a lot of research is directed towards engineering tissues from a patient's own tissues and cells. Some but not all of these developments have reached the clinic. Developments in the field of stem cell therapy are rapid. However, many hurdles are yet to be overcome before these cells can be applied on a large scale in the clinic. The processes leading to genetic abnormalities in cells differentiated from stem cells need to be identified in order to avoid transplantation of aberrant cells. New insights have been obtained on storage and preservation of human materials, a critical step for success of their clinical use. Likewise, quality management systems have been shown to improve the quality and safety of human materials used for transplantation.

Development of a needs assessment system in rehabilitation.

The aim of this project was to develop a standardized, valid and reliable instrument for determining needs of patients and quality of care as perceived by patients. A questionnaire was constructed based upon the Service Quality Model. This model, patient expectations and experiences all play an important role in the questionnaire. The questionnaire contains a general part which includes ten determinants of care, the information the patient got and the perceived quality of care in general. The questionnaire also contains a specific part which includes questions about the actual care for diagnosis related problems. Twenty-four spinal cord injured patients, staying at a Dutch rehabilitation centre, participated in this study. It is concluded that with the developed questionnaire the perceived quality of care according to the Service Quality Model can be assessed. Major contributions of the questionnaire to rehabilitation care will be its ability to highlight patient needs related to identified symptoms, and to provide a tool to signal aspects in the organization that can be improved. Thus it becomes a tool for quality management. Recommendations have been made for further research to make future use of the questionnaire in other settings and populations possible.
