A pre-anesthesia timeout significantly improved patient confidence and safety perceptions. This enhanced patient-centered care led to reduced perioperative pain and greater overall satisfaction.
Area of Science:
- Anesthesiology
- Patient Safety
- Psychometrics
Background:
- Regional anesthesia is a common procedure for orthopedic surgery.
- Patient perception and satisfaction are crucial components of perioperative care.
- Preprocedural verification processes, like the anesthetic timeout, are standard but their impact on patient psychometric outcomes requires further investigation.
Purpose of the Study:
- To evaluate the psychometric outcomes of patients undergoing regional anesthesia.
- To assess patient perceptions of safety, confidence, anxiety, and positive sentiments during a preprocedural timeout.
- To determine the correlation between these perceptions and perioperative pain and satisfaction.
Main Methods:
- A postoperative survey was administered to patients undergoing peripheral nerve blockade for elective orthopedic surgery.
- Numeric rating scales measured patient perceptions of safety, confidence, anxiety, and positive sentiments during the block timeout.
- Logistic regression models analyzed the relationship between these perceptions and perioperative pain and satisfaction.
Main Results:
- Over 90% of the 175 participating patients strongly agreed they felt safe, confident, relaxed, and positive about the timeout.
- Strong positive perceptions during the timeout were significantly associated with lower reported perioperative pain.
- Enhanced feelings of safety and confidence correlated with higher overall patient satisfaction.
Conclusions:
- A patient-centered preprocedural timeout significantly enhances patient confidence and safety perceptions in regional anesthesia.
- Positive patient attitudes fostered by the timeout process are linked to a superior perioperative experience.
- Implementing and optimizing preprocedural timeouts can improve patient satisfaction and potentially reduce pain.
