title: Comparison of nursing interventions classification and current procedural terminology codes for categorizing nursing activities.
abstract: OBJECTIVE
  To compare the frequency with which nursing activity terms could be categorized using Nursing Interventions Classification (NIC) and Current Procedural Terminology (CPT) codes.
  
  
  METHODS
  Descriptive. The sample was 201 patients with AIDS hospitalized 1989-1992 for pneumocystis carinii pneumonia in three US medical centers.
  
  
  METHODS
  Nursing activity terms (n = 21,366) were collected from patient interviews, nurse interviews, intershift reports, and patient records, then were categorized using NIC and CPT codes.
  
  
  RESULTS
  Nursing activity terms were categorized into 80 NIC interventions across 22 classes and into 15 CPT codes. All terms in the data set were classifiable using the NIC system and the majority (60%) of the terms were classified into 14 NIC intervention categories; 6% of the terms were classifiable by CPT codes. The most frequently used CPT code was "pulse oximetry." Significantly (p < .0001) greater numbers of nursing activity terms could be categorized in the NIC system compared to the CPT system.
  
  
  CONCLUSIONS
  Findings provide evidence that NIC is superior to CPT for categorizing nursing activities in this study's population. The findings support the importance of discipline-specific classifications for categorization of health care interventions. Nursing-specific intervention classification systems such as NIC, the Omaha System, and the Home Health Care Classification are essential to defining the contribution of nursing to both quality and cost outcomes.
