Nonmelanoma Skin Cancer Visits and Procedure Patterns in a Nationally Representative Sample: National Ambulatory Medical Care Survey 1995-2007
ABSTRACT BACKGROUND: The rising incidence of nonmelanoma skin cancer (NMSC) is well documented, but data are limited on the number of visits and treatment patterns of NMSC in the outpatient setting. OBJECTIVES: To evaluate practice and treatment patterns of NMSC in the United States over the last decade and to characterize differences according to sex, age, race, insurance type, and physician specialty. METHODS AND MATERIALS: Adults with an International Classification of Diseases, Ninth Revision, diagnosis of NMSC were included in this cross-sectional survey study of the National Ambulatory Medical Care Survey between 1995 and 2007. Primary outcomes included population-adjusted NMSC visit rates and odds ratios of receiving a procedure for NMSC using logistic regression. RESULTS: Rates of NMSC visits increased between 1995 and 2007. The number of visits was significantly higher in men, particularly those aged 65 and older. Fifty-nine percent of NMSC visits were associated with a procedure, and the individuals associated with that visit were more likely to be male, to be seen by a dermatologist, and to have private-pay insurance. CONCLUSIONS: Nonmelanoma skin cancer visit rates increased from 1995 to 2007 and were higher in men than women. Visits to a dermatologist are more likely to be associated with a procedure for NMSC, and there may be discrepancies in treatment patterns based on insurance type and sex.
