ECRI Response to Reviewers' Comments on Technology Assessment:
Air-fluidized Beds Used for Treatment of Pressure Ulcers in the Home Environment
November 7, 2001
1. Dr. David Brienza
Additional wording was added to emphasize that the objective of this report was to determine the efficacy of support surfaces in the treatment of Stage III and IV pressure ulcers in order to provide supporting information for CMS policy NCDs. Therefore, we excluded clinical trials of prevention in our analysis of efficacy.
Corrections were made in direct response to per page and line comments except for explaining the selection of 1985 as a cut off date for reference inclusion.
2. Dr. David Margolis
In the discussion of the normalized healing rate, "wounds" was changed to "pressure ulcers" to reflect that the references for this measurement refer only to pressure ulcers.
3. Dr. George Xakellis
No changes were necessary
The discussion of what types of support surfaces belong in Groups 1, 2, and 3 was enlarged with a more detailed description of each group. Because water mattresses are only included in group 1, one of the clinical studies included in our analysis of Group 2 support surfaces was removed. The data from this study was moved to Question 3's discussion of pressure ulcer healing during the first 30 days of treatment.
