We don't have enough information in the article to pass judgment on whether or not the Muslim doctor deliberately neglected the plight of the Jewish patient. It's an open question. We would know more if we had access to the legal papers in the malpractice suit.
Every Muslim is not a terrorist.
True, but most terrorists in today's world are Muslims. Even if a very small percentage of the 1.2 billion Muslims are terrorists, Muslim terrorism is a vast problem. Furthermore, with the influx of Muslim physicians into the US, expecially into big city and suburban hospitals which treat significant numbers of elderly Jewish patients, the scenario that Debbie describes in this blog is realistic generically, regardless of the particular facts in this particular event in Skokie, IL.
This does not mean that foreign physicians, taken as a group, function as well on average in the American medical system as American educated and trained physicans, taken as a group. There also tend to be more language and cultural differences between foreign physicians and American patients than between American-educated physicians and American patients. These sometimes have a negative impact on the physician-patient relationship and on the quality of care - not even considering the small possibility that the foreign physician might be a Muslim coming from a jihadist ideological background.
