Interventions Employed By Licensed Nurses in Nursing Homes: Refinement and Validation of an Existing Omaha System Nursing Intervention Set

Abstract

Background and Purpose:Demands on long-term services and supports for older adults are growing, although geriatric workforce shortages have persisted for decades. Methods to define and quantify practice of licensed nurses in nursing homes are needed for work optimization within limited nurse resources available in nursing homes. This study aimed to refine and validate observable nursing interventions for nursing homes, using the Omaha System.Methods:Based on the existing corpus of Omaha System interventions for acute care nursing, this multi-phase, multi-method study included a mapping procedure of interviews from licensed nurses in nursing homes, the evaluation of content validity and coding of the interventions using a survey, and inter-observer reliability assessment using TimeCaT.Results:This study validated 57 observable interventions for nursing homes. Of the previously identified acute care nursing interventions, eight interventions were deemed out of scope. One additional intervention was identified. Refined intervention definitions were related to procedures common in acute care settings such as tracheal intubations/extubations and nasogastric tube insertion that were not performed in nursing homes. Expert agreement for content validity and coding of the interventions was high (S-CVI = 0.97), and inter-observer reliability levels (Cohen’s κ value >0.4; proportion agreement >60%) were acceptable for all case studies.Implications for Practice:The validated observable Omaha System nursing interventions for nursing home practice have potential for use in future studies of nursing home practice to understand evidence-based practice, and gaps in care provided. The methodology may be extended to define observable interventions for other roles and settings.
