Highlights The current COVID-19 pandemic has stretched advanced health systems beyond their capacities. Previous pneumonia severity scores have been promoted as useful tools to help clinicians predict outcomes and guide clinical decisions. The CURB-65 and Quick COVID-19 Severity Index scoring systems showed a good performance for predicting in-hospital mortality. The Quick COVID-19 Severity Index score and the Brescia-COVID Respiratory Severity Scale prediction rule showed a good performance for predicting intensive care unit admission.

BACKGROUND Breast‐conserving surgery (BCS) with radiation (BCSR) requires a multidisciplinary care approach between surgeons and radiation oncologists. METHODS This retrospective cohort study examined the use of preoperative radiation oncology consultation and whether use of or distance to this care was associated with treatment choice among 1188 women age ≥ 65 years who were diagnosed with local or regional breast carcinoma in Washington State in 1994 and 1995. Study outcomes included rates of BCSR; BCS alone; and mastectomy; and radiation therapy among women who underwent BCS. RESULTS Only 29% of patients in the current study consulted with a radiation oncologist preoperatively, and less than half of the patients (46.6%) consulted with either a medical oncologist or a radiation oncologist. Among women who underwent either BCSR or mastectomy, the odds of undergoing BCSR among women who had a preoperative radiation oncology consultation were 6.7 times the odds of women who did not have the consultation (P ≤ 0.001). Similarly, the odds of receiving radiation therapy among women who underwent BCS and had a preoperative radiation oncology consultation were 5 times the odds of women who did not have the consultation (P < 0.001). The 3.4% of women who lived > 50 miles from the radiation therapy center had the lowest BCSR rate (15.8%) and had the lowest radiation therapy rate among women who underwent BCS (54.5%), although these findings were not statistically significant in adjusted analyses. CONCLUSIONS A preoperative visit with a radiation oncologist was associated strongly with BCSR use. More should be done to evaluate the role of multidisciplinary consultation in the decision to use BCSR. Cancer 2004;100:701–9. © 2004 American Cancer Society.
