In a national survey of U.S. medical practices, SK&A Information Services, Inc., a leading provider of healthcare information and research, found that office managers wield as much influence as lead physicians in determining the policy for allowing industry sales representatives to visit with physicians. Of the medical practices that allow visits, 48 percent of respondents said the office manager sets the policy while 47 percent said the lead physician sets the policy. Another five percent of survey respondents said the policy is established at the group headquarters level. Moreover, 97 percent said their sales rep visitation policy has been in place for two or more years.
