Question

Nurse Noseinabook wants to find out if the hospital policy at Mercy General Hospital regarding frequency of Foley catheter tubing changes is based on evidence. The policy currently states that Foley catheter tubing should be changed once a month at the same time as the replacement of the Foley itself. The policy was created in 1995 and updated in 2005. Only one reference was indicated as a source of evidence supporting the data: guidelines from the Urologists Association of America (UAA) dated 2002. 25. Nurse Noseinabook searches for the 2002 guidelines and discovers them at the UAA website. They were written in 2002 and were based on 2 correlational studies, 1 descriptive study, and expert opinion. Is this evidence strong enough to base nursing practice or hospital policy on? a. Yes, as long as the power of each study was above 0.80. b. Yes, although it would have been stronger to have a clinical trial included. c. No. These studies do not provide evidence that is strong enough.

Answer 1

In a study a power which is 0.80 or above is an indicator of its quality,worthiness,usefulness accuracy ,etc., and it can be accepted.

Including a clinical trial is an additional benefits because there are high chances for the expected results to change or not. This itself can be a study to analyze the effectiveness of the implemented policy. Conducting a clinical trial can be an added advantage in identifying the strength and weaknesses. Hence this study provides evidences.

Ans:Yes,although it would have been stronger to have a clinical trial included.
