N2 - Purpose. To characterize the patterns of primary surgical care for ovarian cancer in a statewide population according to annual surgeon and hospital case volume. Methods. The Maryland hospital discharge database was accessed for annual surgeon and hospital ovarian cancer case volume for the time intervals: 1990-1992, 1993-1995, 1996-98, and 1999-2000. Annual surgeon case volume was categorized as low (≤4), intermediate (5-9), or high (≥10). Annual hospital case volume was categorized as low (≤9), intermediate (10-19), or high (≥20). Logistic regression models were used to evaluate for significant trends in case volume distribution over time and factors associated with access to high-volume care. Results. Overall, 2417 cases were performed by 531 surgeons at 49 hospitals. The distribution according to annual surgeon case volume was low (56.3%), intermediate (9.2%), and high (34.5%). Between 1993 and 2000, there was no significant increase in the proportion of cases performed by high-volume surgeons (OR = 1.03, 95% CI = 0.81-1.33, P = 0.79). Access to high-volume surgeons was positively associated with care at high-volume hospitals and negatively associated with residence ≥50 miles from a high-volume hospital. The overall hospital volume case distribution was low (49.6%), intermediate (27.6%), and high (22.8%). There was a statistically significant decrease in access to high-volume hospitals between 1990 and 1998 (OR = 0.39, 95% CI = 0.30-0.50, P < 0.0001). Conclusion. A large proportion of primary ovarian cancer surgeries are performed by low-volume surgeons at low-volume hospitals. In light of positive volume-outcomes data for malignancies treated with technically complex operative procedures, increased efforts to concentrate the surgical care of women with ovarian cancer are warranted. Condensed abstract. A large proportion of primary ovarian cancer surgeries are performed by low-volume surgeons at low-volume hospitals.
