The second report---Deprivation and Dispair

As mentioned below there are two new important reports out. This is the second and it looks at the medical care of the detainees (or more precisely, the lack thereof) and the psychological trauma from the years of being imprisoned without charge and with no end in sight.
From the executive summary:

There have been many more such assertions in the intervening years and since. Following an in-depth review of publicly available information related to medical care at Guantánamo—both past and present—as well as consultations with independent civilian medical experts and detainees’ lawyers, the Center for Victims of Torture and Physicians for Human Rights have determined that none of those assertions is accurate. To the contrary, notwithstanding Guantánamo’s general inaccessibility to independent civilian medical professionals, over the years a handful of them have managed to access detainees, review medical records, and interface with Guantánamo’s medical care system to a degree sufficient to document a host of systemic and longstanding deficiencies in care. These include: • Medical needs are subordinated to security functions. For example, prosecutors in a military commission case told the judge explicitly that the commander of Guantánamo’s detention operations is free to disregard recommendations of Guantánamo’s senior medical officer. • Detainees’ medical records are devoid of physical and psychological trauma histories. This is largely a function of medical professionals’ inability or unwillingness to ask detainees about torture or other traumatic experiences during their time in the CIA’s rendition, detention, and interrogation program, or otherwise with respect to interrogations by U.S. forces—which has led to misdiagnoses and improper treatment. • In large part due to a history of medical complicity in torture, many detainees distrust military medical professionals which has led repeatedly to detainees reasonably refusing care that they need. DEPRIVATION AND DESPAIR: The Crisis of Medical Care at Guantánamo 4 • Guantánamo officials withhold from detainees their own medical records, including through improper classification. • Both expertise and equipment are increasingly insufficient to address detainees’ health needs. For example, a military cardiologist concluded that an obese detainee required testing for coronary artery disease, but that Guantánamo did not have the “means to test” him, and so the testing was not performed. With regard to mental health, effective torture rehabilitation services are not, and cannot be made, available at Guantánamo. • Detainees have been subjected to neglect. One detainee urgently required surgery for a condition he disclosed to Guantánamo medical personnel in 2007—and they diagnosed independently in 2010—but he did not receive surgery until 2018 and appears permanently damaged as a result. • Military medical professionals rotate rapidly in and out of Guantánamo, which has caused discontinuity of care. For example, one detainee recently had three primary care physicians in the course of three months. • Detainees’ access to medical care and, in some cases, their exposure to medical harm, turn substantially on their involvement in litigation. For example, it appears extremely difficult, if not impossible, for detainees who are not in active litigation to access independent civilian medical professionals, and for those who are to address a medical need that is not related to the litigation. For detainees charged before the military commissions, prosecution interests have superseded medical interests, as with a detainee who was forced to attend court proceedings on a gurney writhing in pain while recovering from surgery. These deficiencies are exacerbated by—and in some cases a direct result of—the damage that the men have endured, and continue to endure, from torture and prolonged indefinite detention.
