Objective. To examine trends in melanoma visits in the ambulatory care setting. Methods. Data from the National Ambulatory
Medical Care Survey (NAMCS) from 1979 to 2010 were used to analyze melanoma visit characteristics including number of visits,
age and gender of patients, and physician specialty. Tese data were compared to US Census population estimates during the same
time period. Results. Te overall rate of melanoma visits increased ( < 0.0001) at an apparently higher rate than the increase in
population over this time. Te age of patients with melanoma visits increased at approximately double the rate (0.47 year per interval
year, < 0.0001) of the population increase in age (0.23 year per interval year). Tere was a nonsignifcant ( = 0.19) decline in
the proportion of female patients seen over the study interval. Lastly, ambulatory care has shifed towards dermatologists and
other specialties managing melanoma patients and away from family/internal medicine physicians and general/plastic surgeons.
Conclusions. Te number and age of melanoma visits has increased over time with respect to the overall population, mirroring
the increase in melanoma incidence over the past three decades. Tese trends highlight the need for further studies regarding
melanoma management efciency.
1. Introduction
In 2013, the American Cancer Society estimates that there
will be 76,690 new cases of melanoma diagnosed, with 61,300
being melanoma in situ [1]. Melanoma management costs
the US billions of dollars in direct annual expenses [2].
Worldwide, during the past several decades, there has been
a substantial increase in the incidence of melanoma, particu-
larly among white populations [3, 4]. In the US, the incidence
of melanoma also continues to rise. From 1973 to 1994, US
melanoma incidence rates increased 154.4% in males (from
6.8 to 17.3 per 100,000) and 90.2% in females (from 6.1 to 11.6
per 100,000) [5]. Te melanoma incidence rates during 2006
to 2010 reveal a similar trend in males (27.4 per 100,000) and
females (16.7 per 100,000), nearly quadrupling in men and
tripling in women over the past three to four decades [6].
More specifcally, during this period, the incidence rates per
100,000 persons were 31.9 and 20.0 in white men and women,
respectively; 4.7 and 4.4 in Hispanic men and women, respec-
tively; 1.6 and 1.1 in Asian men and women, respectively; and
1.1 and 1.0 in black men and woman, respectively [6].
According to the National Cancer Institute Surveillance
Epidemiology End Results data, from 2006 to 2010, the
median age at diagnosis for melanoma was 61 years, with
approximately 65% of cases occurring in those 55 years and
older [6]. Current estimates of lifetime risk for Americans
experiencing melanoma are 1 in 37 for men and 1 in 56 for
women, which contrasts with the lifetime risk of 1 in 1,500
