Physician knowledge of the diagnosis and management of Rocky Mountain spotted fever: Mississippi, 2002.
Rocky Mountain spotted fever (RMSF), a tick-borne illness that has its highest incidence in the south central and southeastern United States, is often a diagnostic challenge, as patients frequently present with nonspecific symptoms during the early stages of illness. RMSF has a high case fatality rate among untreated individuals, and the median time from onset of symptoms to death is only eight days, making early recognition and treatment of RMSF crucial. In two Mississippi public health districts, 148 primary care physicians were randomly selected and mailed surveys regarding RMSF diagnosis, treatment, and prevention. Eighty-four of the 148 (57%) physicians responded. Responses from different specialties and different health districts were compared using chi square statistics. Almost all (99%) physicians correctly identified doxycycline as the antibiotic agent of choice for treating adults and adolescents. However, only 21% of family practice physicians, and 25% of emergency medicine physicians correctly identified the antibiotic of choice for treating children with RMSF. Twenty-three percent of physicians responded that waiting for the development of a rash before prescribing antibiotics is an appropriate treatment strategy. The current standard of care-doxycycline as the agent of choice among children 8 years of age or younger with suspected RMSF-has not been effectively communicated to all physicians caring for children. Also, many physicians are not familiar with the rationale underlying initiation of antibiotic therapy prior to the development of rash in patients with suspected RMSF. Continuing education efforts should focus on antibiotic selection in pediatric patients and initiation of therapy prior to the onset of rash in appropriate patients.
