The general objectives of the study were to determine whether one can motivate users of health personnel, such as hospitals, to modify their hiring-in-requirements to the actual needs of the job, to restructure health occupational skills, and to develop inservice training programs which permit upward job mobility. Five hospitals, representing a variety of types, cooperated in the study. The research design included a primary care questionnaire, visits to the hospitals, analysis of standards, interviews, and recommendations. Data is tabulated and findings summarized. The summaries reinforce earlier findings in that the more skilled professional (i.e., the RN and LPN) spends large amounts of time on tasks which require very little skill, while persons in entry-level occupations in fact perform some of the more sophisticated functions. Research findings related to marginal medical functions and health manpower employment are discussed, the progress of the general work of the Center for Medical Manpower Studies reported on, and future plans presented. The appendix includes letters, a description of the five participating hospitals, and a reprinted article on the duties of the nurse practitioner. (MW)
