Chapter topics on evaluation and adjuvant therapy include neurologic presentation; radiographic, electrodiagnostic and metastatic evaluation; chemotherapy, external beam radiotherapy, and
stereostatic radiosurgery.
We controlled for technological sophistication, measured by the number of high-technology services offered (trauma,
stereostatic radiology, MRI, PET scanner, kidney transplant, organ transplant, thyroid transplant, bone marrow transplant), because such services are costly and therefore might provide hospitals with a greater impetus to adopt TQM for technical efficiency purposes.
