High-resolution brain SPECT imaging in ADHD.

Children and adolescents with ADHD were evaluated with high-resolution brain SPECT imaging to determine if there were similarities between reported PET and QEEG findings. Fifty-four children and adolescents with ADHD by DSM-III-R and Conners Rating Scale criteria were evaluated. A non-ADHD control group was also studied with SPECT. Two brain SPECT studies were done on each group, a resting study and an intellectual stress study done while participants were doing a concentration task. Sixty-fiver percent of the ADHD group revealed decreased perfusion in the prefrontal cortex with intellectual stress, compared to only 5% of the control group. These are findings consistent with PET and QEEG findings. Of the ADHD group who did not show decreased perfusion, two-thirds had markedly decreased activity in the prefrontal cortices at rest.

Business process reengineering: a remedy for health care.

Health care organizations are facing significant economic constraints that threaten to dismantle core services. The perceived need for reform is great. Business process reengineering may be the strong medicine required to achieve dramatic productivity improvement without jeopardizing the quality and scope of core health care services. Reengineering challenges health care organizations to eliminate functions that do not contribute to a flattened organization structure in which fewer care providers deliver a wider range of health care services. Information technology is used to displace manual checks and controls. Reengineering may facilitate the implementation of contemporary management models, such as patient-focused care, case management and product or program management. The product of reengineering can be enhanced over time by Continuous Quality Improvement.
