Using Qualitative, Community-Based Input to Steer Post-COVID-19 Pharmacy Practice in Substance Use

Background

The coronavirus disease 2019 (COVID-19) pandemic has had a disproportionately negative impact on individuals with a substance use disorder (SUD). A rapidly changing public health and treatment environment has resulted in increased needs for pharmacist engagement in SUD-focused patient care.

Objectives

This study used semistructured interviews of SUD professionals to evaluate where they believe pharmacy practice could better support people at risk of or having SUD in light of challenges posed by the COVID-19 pandemic.

Methods

Professionals dedicated to the care of individuals with SUD were recruited from a large community substance use coalition to participate in a qualitative study examining how pharmacists could take a more active role in SUD prevention, intervention, recovery, and harm reduction (HR). A consensual qualitative research approach was used in data analysis.

Results

Domains identified in analysis included pharmacists as educators of patients and communities, pharmacists as educators of health care providers, pharmacists as advocates for individuals with SUD, the need for increased pharmacist engagement owing to COVID-19 challenges for individuals with SUD, the need for expanded pharmacy practice interventions, and the need for pharmacist self-development.

Conclusion

Increased medication counseling, HR practices, addressing stigma, and community-level education focused on SUD were among the most commonly reported areas for pharmacy practice development. In addition, the urgent need to adjust pharmacy practice in response to the COVID-19 pandemic was also identified by interviewees.

Repeated dose multi-drug testing using a microfluidic chip-based coculture of human liver and kidney proximal tubules equivalents

A microfluidic multi-organ chip emulates the tissue culture microenvironment, enables interconnection of organ equivalents and overcomes interspecies differences, making this technology a promising and powerful tool for preclinical drug screening. In this study, we established a microfluidic chip-based model that enabled non-contact cocultivation of liver spheroids and renal proximal tubule barriers in a connecting media circuit over 16 days. Meanwhile, a 14-day repeated-dose systemic administration of cyclosporine A (CsA) alone or in combination with rifampicin was performed. Toxicity profiles of the two different doses of CsA on different target organs could be discriminated and that concomitant treatment with rifampicin from day6 onwards decreased the CsA concentration and attenuated the toxicity compared with that after treatment with CsA for 14 consecutive days. The latter is manifested with the changes in cytotoxicity, cell viability and apoptosis, gene expression of metabolic enzymes and transporters, and noninvasive toxicity biomarkers. The on chip coculture of the liver and the proximal tubulus equivalents showed its potential as an effective and translational tool for repeated dose multi-drug toxicity screening in the preclinical stage of drug development.
