Women Beware-The Threat of COPD

Transcription

1 Page 1 Speaker: Catherine Cooke attained her Bachelor in Pharmacy from the University of Iowa and then went on to receive her Pharm.D. from the Medical University of South Carolina. Subsequently, she completed a specialty residency in Ambulatory Care/Managed Care through the Philadelphia College of Pharmacy and Science. After post-graduate training, Dr. Cooke served as a full-time Assistant Professor at the University of Maryland School of Pharmacy where she became a Board Certified Pharmacotherapy Specialist. Currently, she is an Independent Consultant working in health care quality and research. In addition, she provides clinical pharmacy services such as hypertension, dyslipidemia and smoking cessation management to patients in Maryland. Her main research interests are in the areas of cardiovascular pharmacotherapeutics and pharmacy services in the managed care environment with specific interest in discrepancies in health care based on sex or ethnicity.

By 2000, the number of women dying from COPD surpassed the number of men. But the rising number of cases in women has not been matched by medical understanding of the disease's apparent gender-bias. This program will increase the awareness of COPD in women. The program will focus on the pharmacists role in identifying patients with COPD (women in particular), reducing the risk factors for developing COPD (such as smoking cessation), and managing the disease. Objectives: Review the etiology and epidemiology of chronic obstructive pulmonary disease (COPD) in women. Identify the impact of COPD on women and the differences in how the disease manifests itself in women compared to men. Provide an update on the efficacy, safety, and role of available treatments in the management of COPD. Describe how pharmacist s can play a critical role in COPD identification, management and education (particularly with women).
