LRB104 17044 RLC 30459 b A BILL FOR HB4583 LRB104 17044 RLC 30459 b 1 AN ACT concerning criminal law. 2 Be it enacted by the People of the State of Illinois, 3 represented in the General Assembly: 4 Section 5. The Unified Code of Corrections is amended by 5 adding Section 3-6-9 as follows: 6 (730 ILCS 5/3-6-9 new) 7 Sec. 3-6-9. Treatment for committed persons with substance 8 use disorders. 9 (a) The General Assembly finds the followings: 10 (1) The Department of Corrections does not currently 11 have extensive medication-assisted treatment programs 12 readily available to meet the needs of all committed 13 persons with opioid use disorder, despite estimates that 14 more than half of the committed population meets the 15 criteria for having a substance use disorder. 16 (2) Providing timely access to medication-assisted 17 treatment in correctional settings reduces recidivism, 18 overdose risk following release, and improves treatment 19 retention. Withholding evidence-based opioid use disorder 20 treatment increases risk for death during detention and 21 upon release. 22 (3) According to the Department of Human Services, up 23 to 75% of parolees who leave prison without treatment for HB4583 - 2 - LRB104 17044 RLC 30459 b 1 an identified substance use disorder resume substance use 2 within 3 months of release. 3 (4) Studies demonstrate that in the first 2 weeks 4 after release, the risk of opioid overdose is 40 times 5 higher for those who were incarcerated compared to the 6 general population. 7 (5) It is the stated position of the U.S. Substance 8 Abuse and Mental Health Services Administration that no 9 justification exists for denying access to medications for 10 opioid use disorder because psychosocial services are 11 unavailable or individuals are unwilling to avail 12 themselves of those services. 13 (6) The U.S. Department of Justice has determined that 14 individuals with opioid use disorder are protected under 15 the Americans with Disabilities Act of 1990. 16 (7) In community-based settings, such as opioid 17 treatment programs and primary care facilities, 18 medication-assisted treatment has been proven to reduce 19 overdose deaths and illicit opioid use. Individuals with 20 opioid use disorder living in correctional settings are 21 entitled to the same level of care as those in 22 community-based settings. 23 (b) In alignment with the State of Illinois Overdose 24 Action Plan, the purpose of this Section is to facilitate 25 timely access to medication-assisted treatment options and 26 therapies to all individuals under the care of the Department HB4583 - 3 - LRB104 17044 RLC 30459 b 1 of Corrections who are diagnosed with opioid use disorder. 2 (c) In this Section: 3 "Authorized health care professional" means a physician 4 licensed to practice medicine in all its branches, a licensed 5 physician assistant with prescriptive authority, a licensed 6 advanced practice registered nurse with prescriptive 7 authority, an advanced practice registered nurse or physician 8 assistant who practices in a hospital, hospital affiliate, or 9 ambulatory surgical treatment center and possesses appropriate 10 clinical privileges in accordance with the Nurse Practice Act, 11 or a pharmacist licensed to practice pharmacy under the 12 Pharmacy Practice Act. 13 "Department" means the Department of Corrections. 14 "Medication-assisted treatment" means the use of U.S. Food 15 and Drug Administration-approved medications, in combination 16 with counseling and behavioral therapies, to provide a whole 17 patient approach to the treatment of substance use disorders. 18 (d) The Department shall ensure all persons under its care 19 are assessed for substance use disorder, as defined in the 20 Substance Use Disorder Act. This process includes screening 21 and assessment for opioid use disorders. For a committed 22 person diagnosed with opioid use disorder, the Department 23 shall offer, or facilitate access to, all medication-assisted 24 treatment options deemed appropriate by an authorized health 25 care professional. The Department shall not impose limitations 26 on the types of medication assisted treatment that may be HB4583 - 4 - LRB104 17044 RLC 30459 b 1 recommended by an authorized health care professional as part 2 of a treatment plan. 3 (e) An individual receiving medication-assisted treatment 4 prior to being committed to a Department of Corrections 5 facility shall be entitled to, upon request, continue such 6 treatment in the medication assisted treatment program for any 7 period of time deemed medically necessary by an authorized 8 health care professional. No person shall be denied 9 participation in medication-assisted treatment program on the 10 basis of a positive drug screening upon entering the 11 Department's custody; nor shall any person receive a 12 disciplinary infraction for such positive drug screen. No 13 person shall be denied participation in medication-assisted 14 treatment based on prior success or failure of any 15 medication-assisted treatment program. 16 (f) For each Parole District, the Department shall develop 17 a plan to facilitate access to medication-assisted treatment 18 for persons diagnosed with opioid use disorder in the 19 community following release. 20 (g) The Department may adopt rules for the implementation 21 of this Section. 22 Section 99.
