The starting compound chosen was the copper thiospinel CuTi& (cubic lattice parameter a = 999.8 pm), prepared at 1100 K from the elements[41. We found that the Cu' ions are mobile at ambient temperature and that the electronic properties of the system are consistent with the following redox reaction:CuTizSl e Cu,Ti2S4 + (1x) Cu@ + (1 -x) eG
ChemInform Abstract The trans-Ir complexes (I) react with PH3 or AsH3 (II) to give the oxidative addition products (III) which are monoisomeric. (Ia) forms with SbH3 the two isomers (IVa) and (IVb). The reactions of the Ir-PH2 system in (IIIb) are explored. The PH2 ligand is easily displaced by Cl or SeH in reactions with HCl or Cl2 and H2Se, and can be oxidized with Se. The chemical behavior of (IIIc) is similar. Both, (IIIb) and (IIIc) react with the Ru dimer (V) to yield the binuclear EH2-bridged title complexes (VI). All the complexes prepared are characterized by NMR spectra. Structures of the title complexes (IIIc) (space group P21, Z=2), (VIa) and (VIb) (for both P21/a, Z=4) are determined (yields not given).
Background
The COVID-19 pandemic has had especially devastating effects on people who use drugs. Due to pandemic protocols in the USA, medication-assisted treatment (MAT) regulations became more flexible, permitting our community-based nonprofit organization to transition its low-threshold MAT clinic to an audio-only telehealth model of care in 2020. Lessons learned have the potential to improve MAT delivery to people with OUD.
Case presentation
This case study describes our transition from a low-threshold community-based in-person MAT clinic to an audio-only telehealth model. We extracted data from electronic health records to describe patient characteristics and to calculate treatment retention rates. Patients were predominantly male (74.4%) and black (90.6%). The mean age was 53 years old with more than half of the clients aged 55 or older. Less than half (42.3%) of the patients lived in stable housing. Patients commonly had self-reported comorbid conditions such as hypertension (35.4%), hepatitis C (23.5%), diabetes (11.9%), human immunodeficiency virus (HIV) (7.2%). A majority of patients (68.6%) reported engagement with behavioral health care. We measure the success of our intervention relative to published retention rates, both overall as well as for in-person and telehealth care. In-person retention rates at 90- and 180-days were substantially higher than telehealth retention rates (93.9% vs 68.4% and 91.5% vs 51.9%, respectively).
Conclusions
Low-threshold medication-assisted treatment in the care of people with opioid use disorder is essential to increasing treatment access and continuity. We found that an audio-only telehealth model was viable. Although we had decreased retention rates following the transition to an audio-only telehealth model, our rates remained excellent compared to published values for in-person MAT care. We call for advocacy and regulations to support continued use of telehealth services throughout and beyond the COVID-19 pandemic.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
