阿片类药物使用障碍的 ED 观察

Participants will have standard Emergency Department visit as per standard operating procedures which should last approximately 3 -5 hours.

Standard visit

Participants will have extended Emergency Department visit by having an observation (which could be up to 23 hours) time in addition to the standard ED visit. In addition, information will be gathered about about the participants, use of opioids, healthcare visits, the quality of health, life, and treatment, and other topics. Urine or saliva or both may also be collected.

Emergency Department Observation Units (EDOU) would allow the highest risk patients - those presenting for nonfatal overdose - to receive their first dose of BUP before leaving the ED.

Operationally defined to include placement in an observation unit and/or placement under observation status with care provided by Emergency Medicine and/or other services (e.g., Internal medicine, Psychiatry)

Receipt of ED-initiated BUP will be operationally defined to include administration of BUP and/or prescription for BUP as part of the ED/Emergency Department Observation (Units) (EDOU) visit. This measure will be abstracted from the health record primarily.

Receipt of ED-initiated/expedited BUP will be operationally defined to include the provision of a specific "warm" referral or transfer of care to a provider, clinic, or treatment setting with the capacity to administer and/or prescribe BUP within 24 hours of completion of the ED/EDOU visit. Eligible transition of care will be will described further in the Manual of Operations (MOP) and will include direct transport or handoff to an outpatient provider immediately from the ED, provision of an appointment within 24 hours (with a specific time and location), transfer to general inpatient or inpatient OUD/addiction treatment. Neither confirmation of a completed appointment (i.e., patient shows up and is seen) nor receipt of BUP at the dedicated follow-up appointment will be required as the patient and treating provider may elect to treat with alternative regimes (e.g., methadone, naltrexone). This measure will be abstracted from the health record primarily.

Receipt of ED-initiated MOUD, inclusive of BUP, methadone, or naltrexone.

Successful linkage to formal addiction treatment will be defined as confirmed attendance at formal addiction treatment for OUD following completion of the ED/EDOU visit. Formal addiction treatment will be those treatments consistent with the American Society of Addiction Medicine's (ASAM) level of care (1-4) and will include a range of clinical settings, including office-based providers of BUP or naltrexone, Opioid Treatment Programs (OTPs), intensive outpatient, inpatient, or residential treatments. Means of confirmation will include direct contact with the facility and/or treating clinician or other objective means (e.g., medical record review).

Engagement in treatment for OUD will be defined as confirmed enrollment in formal addiction treatment for OUD on the 30th day following completion of the ED/EDOU visit. Attendance at two or more visits for formal addiction treatment within the 30-day period also constitutes engagement.

Measured by the Timeline Follow-Back (TLFB) procedure will be used to elicit the participant's self-reported use of illicit substances at baseline and throughout study participation.

EuroQol-5 Dimensions (EQ-5D): The EuroQol is a structured interview that collects general health information applicable to a wide range of health conditions and treatment, providing a simple descriptive profile and a single index value for health status between 0 (dead) and 1 (full health).

Assessment of quality of life in seven health domains (physical function, fatigue, pain interference, depressive symptoms, anxiety, ability to participate in social roles and activities, and sleep disturbance) all assessed using the PROMIS-29 questionnaire. PROMIS-29 is scored on a T-score metric with a mean of 50 and a standard deviation of 10 in the U.S. general population, with a higher score representing more symptoms.

The PHQ-9 is a 9-item instrument used for screening, diagnosing, monitoring and measuring the severity of depression. Each item is rated from 0 (not at all) to 3 (nearly every day). Total scores range from 0-27. Scores are interpreted as follows: Minimal Depression: 0-4, Mild depression: 5-9, Moderate depression: 10-14, Moderately severe depression: 15-19, Severe depression: 20-27.

Treatment Effectiveness Assessment (TEA) scale is comprised of 4 questions about substance use, health, lifestyle, and community. Participants respond the questions on how they have improved in that area on a scale from 1 (not better at all) to 10 (very much better). Higher scores indicate overall improvement and effectiveness of treatment.
