OBJECTIVE: Adolescents are a primary reservoir for propagating
pertussis infection. This study aimed to describe diagnosis and testing practices for adolescent
pertussis among a national sample of primary care physicians. METHODS: From January to March, 2007 we administered a written survey to a United States sample of American Medical Association physicians that included 725
family practitioners (FPs) and 725 general
pediatricians (PDs). RESULTS:
Response rate was 60% (n=702). Overall, 16% of respondents indicated that they did not test adolescents for
pertussis as part of their clinical practice. A similar proportion did not recognize the clinical manifestations of
pertussis in a standardized adolescent case patient. FPs were less likely than PDs to test for
pertussis in general and to diagnose the case patient with
pertussis. Barriers to testing adolescents for
pertussis included delay in obtaining test results (52%), inconvenience of sample collection (29%), lack of testing supplies (29%), lack of familiarity with testing protocols (28%) and cost (22%). CONCLUSION: Our results suggest that a substantial number of primary care physicians do not utilize
pertussis testing and may not be able to recognize the
clinical symptoms of this
infection in adolescents. Interventions to improve physician knowledge about this important
public health issue may be warranted.
