A survey of all hospitals accredited by the American Hospital Association was made to ascertain how the physically handicapped performed at jobs in medical laboratories. Detailed questionnaires were sent to laboratory directors, and the results were processed by computer to determine whether correlations exist between the number of disabled persons employed and the type of hospital, size of laboratory, and geographic location, and whether the type of disability has a significant relationship to type and time of training, job assignment, level of responsibility, and quality of work. A field study and demonstration program were also conducted in three states using interviews with the disabled and their supervisors. Most disabilities did not prevent successful performance of laboratory jobs, but there was a widespread lack of communication between counselors who advised the disabled and those who hired and trained workers. Of the 693 disabled included in the hospital survey, 91 percent were performing satisfactorily on the job. Attendance records were equal to or better than those of other employees; moreover, it was found that disabled persons remain on the job longer than the nondisabled. (BC)
