A client in the ICU experiences a sentinel event related to central line catheter care that resulted in serious injury. What performance improvement (PI) model should the unit use to identify errors that led to the sentinel event?

Informed consent is a fundamental component of ethical research involving human participants. It ensures that individuals voluntarily agree to participate after receiving full disclosure about the purpose, risks, benefits, and their rights.

Rationale for correct answer:

D. Right to self-determination: This right means individuals have the freedom to make their own choices-including the right to refuse participation in research-without pressure, coercion, or fear of losing care.

Rationale for incorrect answers:

A. Right not to be harmed: This right protects participants from physical, emotional, or psychological harm during a study. While the situation is ethically concerning, the client did not report harm from the research itself-only pressure to participate.

B. Right to full disclosure: Full disclosure involves providing complete and understandable information about the research, including its purpose, risks, benefits, and procedures.

C. Right to privacy and confidentiality: This right pertains to the handling of personal information-ensuring that any data collected is kept confidential and used appropriately. There's no indication in the scenario that the client’s private health information was mishandled.

Take home points:

• The right to self-determination is foundational in research ethics, requiring that all participation be voluntary and free of coercion.
• Pressure, manipulation, or fear of withdrawal of care invalidates informed consent.

When you implement an intervention you must choose appropriate measures. Distinguish process measures (was the intervention delivered?), behavioral measures (did patients change what they do?), and clinical/physiologic outcomes (did health status change?).

Rationale for correct answer:

D. Checking patients’ blood sugars: Blood glucose (or A1c) is a clinical outcome closely tied to medication adherence for diabetes and therefore a meaningful measure of whether the educational intervention produced the desired behavioral effect.

Rationale for incorrect answers:

A. Measuring the patients’ weight: Weight may change from many factors and is not a direct indicator of diabetes medication adherence over a short timeframe.

B. Chart auditing teaching sessions: This is a process measure (documents that teaching occurred), not a measure of patients’ behavior or clinical response.

C. Observing patients viewing the videos: That shows exposure to the intervention (process), not whether they actually take medications correctly and on time.

Take home points:

• Match your measure to the outcome: process (was it done?), behavior (did patients change actions?), or clinical outcome (did health improve?).
• When direct behavioral measures aren’t available, use meaningful clinical proxies (e.g., blood sugars for diabetes adherence), but be aware they can be influenced by other factors.
