The Chief Nurses, US Army Health Services Command and Office of the Surgeon General, Department of the Army (HQDA) are interested in the validity of the 1.11 nonproductive factor used in present staffing guides (AR 570-4, 17 Nov 75 and DA Pam 570-4, 8 Apr 74), especially for the Department of Nursing at the Army Medical Department activities. The purposes of the study were to determine the validity of the present factor, to identify other allowable categories of nonproductive time that should be used in determining the nonproductive factor, and to recommend a new nonproductive factor if the present factor is not valid. It was concluded that: (1) The present 1.11 factor does not appear to be valid for all MTFs; (2) A separate factor (or range of factors) according to facility size (MEDCEN, Large MEDDAC, or Small MEDDAC) would offer more appropriate standards; (3) Several additional categories of lost time have been identified for consideration in determining a new nonproductive standard; (4) A model, similar to the Air Force Standard Workweek and Man-Hour Availability, could be developed using the data from the identified categories of lost time; (5) Consideration could be given by the Secretary of Defense to using the models as standards for all Services in compliance with GAO recommendations; and (6) No new specific factor or model has been developed.
