28 CFR § 549.65 - Refusal to accept treatment.
(a) When, as a result of inadequate intake or abnormal output, a physician determines that the inmate's life or health will be threatened if treatment is not initiated immediately, the physician shall give consideration to forced medical treatment of the inmate.
(b) Prior to medical treatment being administered against the inmate's will, staff shall make reasonable efforts to convince the inmate to voluntarily accept treatment. Medical risks faced by the inmate if treatment is not accepted shall also be explained to the inmate. Staff shall document their treatment efforts in the medical record of the inmate.
(c) When, after reasonable efforts, or in an emergency preventing such efforts, a medical necessity for immediate treatment of a life or health threatening situation exists, the physician may order that treatment be administered without the consent of the inmate. Staff shall document their treatment efforts in the medical record of the inmate.
