Using a Systems Approach in Developing a Survey to Assess the Contributing Factors to Needlestick Injuries
Needlestick injuries (NSIs) are the result of multiple factors which interact in a complex manner. In an attempt to understand the causes of NSIs, a systems approach was adopted. An extensive literature review identified behaviors, equipment, safety and interpersonal environments, and administrative policies and procedures as potential contributors to NSIs. Two phases in the development of an instrument that measures the contributions of the individual, organization, and environment are reported. In phase one, a questionnaire was developed using the critical incident technique and tested on nursing and paramedic students and nursing professors. In phase two, a revised survey was administered to 205 nurses. The following factors representing different levels of a health care system emerged: safety environment, stressors, conflicting or conflicting procedures, critical behaviors, and knowledge. The discussion addresses how the questionnaire can be used to test the relative influences of these factors on the occurrence of NSIs and generate recommendations for system-wide interventions.
