Section snippets
Sample
A survey questionnaire was distributed twice to all 188 OMFS registered with the Michigan Society of OMFS in July 2005. Anonymous prepaid postage return envelopes were provided. The surveys were numbered for the sole purpose of preventing duplication of data entry. The individual respondents were never identified with their answers.
Survey
A 2-part questionnaire was developed to allow for simple data acquisition. The questions were as follows:
- 1)
Please indicate the maximal INR you would tolerate for
Results
All 188 surgeon members of the Michigan Society of OMFS received an initial mailing followed by a duplicate second mailing 2 weeks later. Fifteen of the surgeons were excluded because of retirement or incorrect address. One hundred twenty-seven surveys were returned for data collection for an overall response rate of 72.8%; however, 4 surveys were excluded. Three because of incomplete information, and 1 respondent returned both surveys with the same information.

Discussion
In patients requiring anticoagulation, INR values are maintained within a therapeutic range set forth by recommendations provided by various anticoagulation committees. An INR range between 2.0 to 3.0 is deemed appropriate for patients at risk for arterial and venous thrombosis.48, 49, 50, 51, 52, 53, 54, 89 An INR range from 2.5 to either 3.5 or 4.0 is advocated for mechanical heart valves by American Heart Association/American College of Cardiology48, 49 and European Society of
