title: How unit level nursing responsibilities are structured in US hospitals.
abstract: OBJECTIVE
  To describe (1) the extent to which acute and intensive care units use the elements of nursing models (team, functional, primary, total patient care, patient-focused care, case management) and (2) the deployment of non-unit-based personnel resources.
  
  
  BACKGROUND
  The lack of current data-based behavioral descriptions of the extent to which elements of nursing models are implemented makes it difficult to determine how work models may influence outcomes.
  
  
  METHODS
  Nurse managers of 56 intensive care units and 80 acute care adult units from 40 randomly selected US hospitals participated in a structured interview regarding (1) day-shift use of patient assignment behaviors associated with nursing models and (2) the availability and consistency of assignment of non-unit-based support personnel.
  
  
  RESULTS
  No model was implemented fully. Almost all intensive care units reported similar assignment behaviors except in the consistency of patient assignment. Non-intensive care units demonstrated wide variation in assignment patterns. Patterns differed intra-institutionally. There were large differences in the availability and deployment of non-unit-based supportive resources.
  
  
  CONCLUSIONS
  Administrators must recognize the differences in work models within their institutions as a part of any quality improvement effort. Attempts to test new work models must be rigorous in the measurement of their implementation.
