1. Researchers investigated surgical checklist intervention to reduce infection rates and unplanned OR returns. How did this intervention affect outcomes?
Answer: C
The surgical checklist intervention indicated positive outcomes for infection rates.
The intervention utilizing surgical checklists resulted in a statistically significant p-value, showcasing positive outcomes concerning infection rates.
A) p-value indicates insignificance for OR returns
This option is incorrect as it suggests that the p-value did not show significant results regarding operating room (OR) returns. However, the focus of the checklist intervention was primarily on reducing infection rates, and any implications regarding OR returns would need to be separately addressed.
B) Negative impact on infection rates
This option is incorrect because it contradicts the findings of the research. The surgical checklist intervention was designed to enhance safety and reduce complications, including infections, and did not demonstrate a negative impact on infection rates.
C) p-value indicates positive outcomes for infection rates
This option is correct as the research findings support that the surgical checklist intervention led to a statistically significant reduction in infection rates, as indicated by the p-value. This demonstrates the effectiveness of the intervention in improving patient outcomes.
D) No impact
This option is incorrect as it implies that the surgical checklist had no effect on infection rates. The research demonstrated that the checklist intervention did have a measurable positive impact, thereby refuting the notion of "no impact."
Conclusion
The correct answer is definitively supported by the evidence showing that the surgical checklist intervention resulted in a statistically significant reduction in infection rates, as indicated by the p-value. All other options fail to accurately reflect the outcomes of the intervention, either misrepresenting the results or suggesting a lack of impact where evidence suggests otherwise.
