Nidal Hasan's supervisor at the Walter Reed Medical Center warned that the psychiatrist was unprofessional and lazy in a harshly critical performance evaluation in 2007. Hasan "demonstrates a pattern of poor judgment and a lack of professionalism," the report states, noting that he proselytized to his patients and allowed a homicidal patient to escape from the emergency room. Hasan only treated 30 patients in 38 weeks, the report states, about a tenth of other psychiatrists' workload.
Despite the scathing review, Hasan treated some of the most at-risk soldiers. The report said Hasan "was able to self-correct with supervision," but leading psychiatrists say he would never have been able to get a job in civilian life with that report on his record. "Even if we were desperate for a psychiatrist, we would not even invite him for an interview," the chief of one Baltimore-area practice told NPR.
