“It isn’t a shilah.”
After I posted that I realized that it might be misleading. She has consulted with distinguished rabbis over exactly what and what not a doctor can do to treat patients on Shabat, and under what conditions. We also rule leniently in matters of doubt because of pikuach nefesh. And very little that doctors do on Shabat is actually melachah d’oraita. The “it isn’t a shilah” is that a doctor does not distinguish between Jewish and non-Jewish patients, not that there isn’t a lot of halachah that one must learn in order to treat patients on Shabat.
