CINAHL uses some subject headings that include acronyms at the end of the heading, such as Animal Assisted Therapy (Iowa NOC), Sensory-Perceptual Alterations (NANDA), or Risk Identification (Iowa NOC). These acronyms refer to nursing classification systems. When searching CINAHL for a topic, it is recommended that a more general subject heading be used. Only use the nursing classification subject headings if you are looking for records that specifically mention the classification.
NANDA. North American Nursing Diagnosis Association (added to CINAHL in 1989)
Iowa NIC. Nursing Interventions Classification from the Iowa Intervention Project (added to CINAHL in 1994)
Saba HHCC. Saba Home Health Care Classification (added to CINAHL in 1995)
Iowa NOC. Nursing Outcomes Classification from the Iowa Intervention Project (added to CINAHL in 1999). Records are indexed with IOWA NOC terms only if the document states its use or inclusion.
