Relationship Between Physician Supply and Breast Cancer Survival: A Geographic Approach

Abstract

Breast cancer is the most common cancer in women, accounting for nearly 30% of all female cancers. Breast cancer is the second leading cause of cancer mortality in women in the US. During the last two decades, the benefits of early detection, early intervention, and postoperative treatment have resulted in decreased breast cancer mortality in the US general population. However, the distribution of breast cancer mortality varies among geographic regions of the US. The reasons for this variation remain largely unknown. We choose to look for a possible association between the numbers of physicians in each city within the State of Florida and breast cancer survival among women aged 40+ residing in that particular city. Using Cox Proportionate Hazard Modeling, we found a direct association between the number of physicians practicing in a particular city and breast cancer survival in that particular city (P=0.0153), while controlling for other known risk factors affecting survival. To our knowledge, this is the first study to report an association between physician supply and cancer survival within defined geographic areas. This association shows as physician density consistently dropped in a defined geographic area so did time of survival among women with breast cancer.

Pediatric Orthopaedic Workforce in 2014: Current Workforce and Projections for the Future

“…In a recent study of POS fellowship graduates, 86% chose employment based on geography and family preferences. [33][34][35][36] Another interesting finding is the increase in the percentage of female pediatric orthopaedists being trained. Pediatric specialists cluster in dense population areas because of greater access to patients, technology, and children's hospitals.…”

Influence of Primary Care on Breast Cancer Outcomes Among Medicare Beneficiaries

“…[57][58][59][60][61] Research has also suggested a strong relationship between the receipt of primary medical care and recommendations for breast cancer screening. 1,62,63 Our study confi rms the fi ndings of others that Medicare benefi ciaries having greater numbers of primary care physician visits were more likely to receive mammography before diagnosis and were more likely to have early-stage breast cancer.…”

Higher Physician Density is Associated with Lower Incidence of Late-stage Colorectal Cancer

“…Higher physician density has been associated with earlier stage of diagnosis of malignant melanoma 28 , lower incidence of cervical cancer 29 and earlier stage at diagnosis of breast cancer 30,31 . There has been limited prior research examining the relation between physician density and CRC.…”
