Abstract
I just finished reading with interest the report by Roach et al entitled “The Relationship Between Duration of Physical Therapy Services in the Acute Care Setting and Change in Functional Status in Patients With Lower-Extremity Orthopedic Problems” in the January 1998 issue. I agree with authors that more outcome research is needed in acute care settings, using standardized tools. I commend the authors for their research. The authors refer to a study by Van Dillen and Roach1 and state that the Acute Care Index of Function (ACIF) has established reliability and validity in an acute care setting. The authors fail to mention that the study by Van Dillen and Roach was completed on a neurological case mix to the exclusion of other types of conditions. The inferential leap from neurological to orthopedic conditions is tenuous.… Kathryn E Roach, PhD, PT Associate Professor, Division of Physical Therapy, University of Miami School of Medicine, 5915 Ponce de Leon Blvd, Coral Gables, FL 33146, (kroach@mednet.med.miami.edu)
