Determinants of First Practice Location Choice by New Physicians Chiu-Fang Chou 1,2, Dr.PH and Anthony T. Lo Sasso 2, Ph.D., Midwest Center for Health Workforce Studies 1, Division of Health Policy and Administration 2 University of Illinois at Chicago, Chicago, Illinois Introduction Materials and Methods This study is aimed at understanding how new physicians choose their initial practice locations. There is considerable disagreement on the role of malpractice premiums on physicians’ practice decisions. New physicians’ practice location decisions can have a lasting impact on the future healthcare workforce because relocation can be particularly costly for physicians. The objectives of this study are threefold: (1) The impact of malpractice premiums and laws affecting premiums; (2) Policies aimed at encouraging physicians to practice in underserved areas (3) The ethnic and racial backgrounds of physicians. Statistical analysis involved fixed effects models to examine the factors affecting the choice of initial practice location by new physicians. Data are from a unique survey of exiting medical residents acquired by the HRSA-funded New York Workforce Center at SUNY Albany. These data are matched to data on malpractice premiums from Medical Liability Monitor. Additional location information is from the Area Resource File (ARF). The sample consists of 9,137 physicians who just finished their residency training in New York and California in and who are beginning their careers in patient care. The dependent variable is the choice of location among the 357 metropolitan statistical areas (MSAs) and non-metropolitan areas within each state in the United States. Where appropriate, independent variables have been weighted by area population. Other local market characteristics include the number of hospital beds, per capita income, and the local unemployment rate. Results Conclusions  The results suggest that malpractice premiums may be an important factor for some risky subspecialties. New surgeons were less likely to practice in areas with increasing malpractice premiums. OB/GYNs were less sensitive to malpractice premiums than were surgeons. PCPs appeared to be drawn to areas with higher malpractice premiums, suggesting a potential substitution effect.  Symmetric results were observed for the impact of state damage award caps. New surgeons and OBs were more likely to practice in areas with caps. New PCPs were less likely to practice in areas with caps.  The results suggest that health professional shortage areas may not be an important factor. Only OB/GYNs and PCPs without debt (18% and 36%of the respective samples) were more likely to practice in areas with HPSAs. Suggesting the program as structured does not appear to draw physicians.  Racial/ Ethnicity matching plays an important role on location choices for new physicians. he estimates are relevant for policy given the amount of interest in increasing the presence of minority physicians in predominantly minority communities. Educational debts is also found to be a factor influencing location choice of new physicians.  Limitation of this study:  This study used the new physicians who finished their residency training in New York and California states, which are urban state.  Malpractice data is limited because it does not have detailed information on the number of physicians that each company represents in the state; so it is rough average premium rather than a weighted average premium. This map displays MSAs chosen by new physicians. The most frequently chosen option for all three specialty groups in the sample located in New York City. The second and third most common location was Nassau-Suffolk, NY (Long Island) and Los Angeles-Long Beach, CA.

Hypothesis are the following: Hypothesis 1: New physicians will be more likely to practice in a place with lower malpractice premium rate. Hypothesis 2: New physicians will be more likely to practice in a place with a malpractice damage award cap. Hypothesis 3: New physicians with higher educational debt will be more likely to practice in a health professional shortage area. Hypothesis 4: New physicians will be more likely to locate in areas with higher proportion of the population of their race. The determinants of first practice location choices for physicians vary by specialty.  Policy makers who create programs regarding the physician workforce need to consider the different needs of physicians in different specialties.  Increasing malpractice premiums do appear to deter some specialists from locating in certain area; although malpractice damage award caps may be an effective tool for state policy makers to attract some traditionally high malpractice premium specialists.  Policy makers need to reevaluate the existing programs regarding HPSAs and to study the impacts of these program on physicians’ distribution or promote these programs to new physicians.  Table 4 Racial/Ethnicity matching: Racial/Ethnicity matching plays an important role on location choices for new physicians. That is, minority doctors appear to prefer to practice in areas that have more population of their own race and ethnicity. For example, in the Hispanic community, the results indicate that 1 % increase in the proportion of the population that is Hispanic makes a Hispanic OB/GYN 13.7% increase in the probability of locating in an area. The estimate is statistically significant for OB/GYNs (p<.05), PCPs (p<.01) and surgeons (p<.1).

Premiums grew quite slowly between 1998 and 2000, but they increased rapidly after 2000, with OB/GYN premiums increasing roughly 50% by 2003 and surgeon and PCP premiums increasing over 70% by In 2003 OB/GYN premiums were still nearly 1.5 times greater than premiums faced by surgeons and nearly 5 times greater than premiums faced by PCPs. Table 1 presents the characteristics of locations chosen by new physicians trained from NY and CA during Malpractice premiums average nearly $65,000 annually for OB/GYNs and roughly half that figure for surgeons. PCPs by contrast faced premiums of roughly $12,000 per year. Beyond the striking difference in malpractice premiums, location differences between the three specialist types were not particularly apparent. Surgeons appeared somewhat more likely to locate in states with malpractice damage award caps.

No significant effect on the probability of choosing to locate in a given area for OB/GYNs, a statistically significant positive effect for PCPs. The magnitude of the result indicates that a one standard deviation increase in malpractice premiums for surgeons (approximately $17,500) would make a surgeon 0.1percentage point less likely to move to a given location, or roughly 8%.  Malpractice damage caps: Statically significant (p<.01) for surgeons and no statistically significant effect for OBs. The magnitude of the result indicates that surgeons are 0.28 of a percentage point more likely to locate in an area with a cap – suggesting a 23.9% (for surgeons) increase in the probability of locating in an area.

However, PCPs with no debt are significantly more likely to locate in areas with higher HPSA values. The magnitude of the result for PCPs without educational debt suggests that they are 14% more likely to locate in an area that is entirely a HPSA.
