The correct answer is D, "A monitoring system must be in place following implementation of interventions," as this is essential to the quality improvement (QI) process. According to the Certification Board of Infection Control and Epidemiology (CBIC) guidelines, a key component of any QI initiative, such as studying the incidence of infections in patients with triple lumen catheters, is the continuous evaluation of interventions to assess their effectiveness and ensure sustained improvement. A monitoring system allows the infection preventionist (IP), Cancer Committee, and Intravenous Therapy Department to track infection rates, identify trends, and make data-driven adjustments to infection control practices post-intervention (CBIC Practice Analysis, 2022, Domain II: Surveillance and Epidemiologic Investigation, Competency 2.4 - Evaluate the effectiveness of infection prevention and control interventions). This step is critical to validate the success of implemented strategies, such as catheter care protocols, and to prevent healthcare-associated infections (HAIs).
Option A (establish subjective criteria for outcome measurement) is not ideal because QI processes rely on objective, measurable outcomes (e.g., infection rates per 1,000 catheter days) rather than subjective criteria to ensure reliability and reproducibility. Option B (recommendations for intervention must be approved by the governing board) is an important step for institutional support and resource allocation, but it is a preparatory action rather than an essential component of the ongoing QI process itself. Option C (study criteria must be approved monthly by the Cancer Committee) suggests an unnecessary administrative burden; while initial approval of study criteria is important, monthly re-approval is not a standard QI requirement unless mandated by specific policies, and it does not directly contribute to the improvement process.
The emphasis on a monitoring system aligns with CBIC’s focus on using surveillance data to guide and refine infection prevention efforts, ensuring that interventions for triple lumen catheter-related infections are effective and adaptable (CBIC Practice Analysis, 2022, Domain II: Surveillance and Epidemiologic Investigation, Competency 2.5 - Use data to guide infection prevention and control strategies). This approach supports a cycle of continuous improvement, which is foundational to reducing catheter-associated bloodstream infections (CABSI) in healthcare settings.
