Telehealth Use and Legal Considerations in Drug Health Services During Pandemics: Systematic Scoping Review
Background: The COVID-19 pandemic impacted patients with substance use disorder (SUD) more than the general population and resulted in substantially increased emergency department admissions. Routine care of patients attending drug health services during the pandemic transitioned, with telehealth being important in delivering appropriate care. However, telehealth introduces unique risks such as privacy, confidentiality, and data safety. Providing health care through telehealth may fail if the legal impacts are not fully identified and acted on by health professionals. It also poses unintended risks for patients and can result in ineffectiveness, damages, medical negligence, and detracts from the best intentions of governments and health professionals. Understanding the legal framework ensures that medical professionals operate health care through telehealth within the law. Providing health care successfully through telehealth depends on the balance between innovation and legal compliance. By considering these aspects, clinicians and practitioners can provide effective and safe telehealth services during pandemics or any other natural disaster. Objective: We aimed to explore the legal impact of autonomy consent, confidentiality, privacy, data security, professional indemnity, and liability when delivering telehealth to patients with SUD. The scoping review also aimed to provide legal, ethical, and clinical considerations to minimize legal risks with using telehealth in drug health service outpatient settings. Methods: We performed a scoping review to provide an overview of existing research, statutes, and case laws for the incorporation of clinical, ethical, and legal considerations into telehealth use. Six databases for medical and 6 databases for legal publications were searched, as well as Australian national and selected international regulatory standards. Medical articles published up to June 2022 were included in this review. Our search yielded 1436 publications, 614 abstracts were reviewed, and 80 published studies met the inclusion criteria from 614 legal and medical search results. Current regulations related to technology use in drug health services, relevant cases, and international regulatory standards are discussed. Results: In total, 43 legal documents including 15 statutes, 4 case laws, and 37 medical publications were reviewed. The themes arising from the literature were consent and autonomy (20/80, 25%), confidentiality (8/80, 10%), privacy (8/80, 10%), data security (7/80, 9%), and professional indemnity issues (3/80, 4%) in telehealth use. Further, 24 studies identified legal issues associated with telehealth use in patients with SUD. Conclusions: Our review identified potential legal issues associated with telehealth use in patients with SUD. Several legal and medical research articles provide frameworks, codes of conduct, or suggestions for clinicians to consider, but there was little discussion or evidence of how legal considerations are being applied when providing telehealth consultations at drug health services. Clinicians should be aware of the medicolegal implications when providing health care via telehealth at drug health services.

Prevalence and factors associated with polydrug use among clients seeking treatment for alcohol misuse
Introduction: The aim of this paper was to examine the client and psychosocial characteristics associated with polydrug use in patients with alcohol misuse as their primary drug of concern (PDC) seeking treatment from substance use treatment centres.Methods: Self‐report surveys were undertaken with clients attending 1 of 34 community‐based substance use treatment centres across Australia with alcohol as their PDC. Survey items included client's socio‐demographic characteristics, level of alcohol dependence, use of other drugs including tobacco, health and wellbeing factors including health‐related quality of life. The factors associated with polydrug use (alcohol use concurrent with at least one other drug) were examined.Results: In a sample of 1130 clients seeking treatment primarily for alcohol problems, 71% reported also using another drug. The most frequently used drug was tobacco (50%) followed by cannabis (21%) and benzodiazepines (15%). Excluding tobacco use, 35% of participants reported polydrug use. Factors associated with any polydrug use were younger age, lower education levels, lower levels of mental health related quality of life and housing risk (i.e., risk of eviction or experienced homelessness in past 4 weeks). When tobacco was excluded, factors associated with polydrug use were age, lower physical and mental health‐related quality of life, and housing risk.Discussion and Conclusions: Most adults seeking treatment for alcohol misuse as their PDC reported using another drug in addition to alcohol. Treatment services should be designed accordingly to maximise the likelihood of treatment engagement and success.

‘It’s a fragile open door’—enhancing COVID-19 vaccination rates in people receiving treatment for substance use disorder
Background: People with substance use disorder are at high risk of harms from COVID-19 infection. Vaccine hesitancy is common in this population and compounds pre-existing barriers to accessing health care. A drug and alcohol service in Sydney, Australia introduced strategies to enhance COVID-19 vaccination in people receiving opioid agonist treatment (OAT). We report vaccination outcomes and staff experiences of this. Methods: This mixed methods study (i) retrospectively evaluated vaccine uptake in people accessing OAT and (ii) explored perceptions of staff who delivered vaccination interventions through surveys and semi-structured interviews. Results: Of the 984 patients receiving OAT on 9 December 2021, 90.9% had received the first COVID-19 vaccination and 86.7% the second. Australia wide vaccination rates on that date were 93.1% and 88.7% for first and second doses, respectively. Staff commented that having a deep knowledge, understanding and connection with the patient group drove implementation and success of vaccination interventions. This was further supported by staff engagement with the vaccination interventions, and communication and sharing information, both between staff and with patients. Conclusion: High rates of COVID-19 vaccination can be achieved in a vulnerable population. Engaged staff providing information and facilitating access to healthcare underpin this success.

COVID-19 Impact on Australian Patients with Substance Use Disorders: Emergency Department Admissions in Western Sydney before Vaccine Roll Out
Background: In this study, we determined the impact of the COVID-19 pandemic on Western Sydney patients with substance use disorders (SUD) by comparing emergency department (ED) admission rates before and after the onset of the COVID-19 pandemic and before the rollout of COVID-19 vaccination. Methods: ED admission data for patients with SUD were retrieved from the local electronic medical record (eMR) on the hospital central database. ED data collected from 25 January to 25 July 2019 (before the COVID-19 pandemic) were compared with data from 25 January to 25 July 2020 (early pandemic). ED admission reasons were categorised based on the presenting complaints and ED diagnoses. Results: Despite an overall reduction in ED admissions during the early pandemic, compared to the pre-pandemic period, admissions for patients with SUD increased significantly (1.7% to 3.4%, p < 0.01). ED admission rates related to infection (0.05% to 0.12%, p < 0.01), local infection (0.02% to 0.05%, p < 0.01), trauma (0.06% to 0.12%, p < 0.01), alcohol (0.01% to 0.03%, p < 0.05), and other issues (0.06% to 0.10%, p < 0.05) increased significantly among Indigenous patients with SUD. ED admission rates related to drugs (0.12% to 0.39%, p < 0.01), infection (0.21% to 0.34%, p < 0.01), local infection (0.07% to 0.18%, p < 0.01), gastrointestinal (0.15% to 0.23%, p < 0.05), trauma (0.14% to 0.25%, p < 0.01), alcohol (0.36% to 0.74%, p < 0.01), and ‘other’ issues (0.47% to 0.91%, p < 0.01) increased significantly among non-Indigenous patients with SUD. Four cases of COVID-19 were reported among these patients. Conclusions: There was an increase in ED admissions for patients with SUD in the initial six months of the COVID-19 pandemic (before vaccine rollout), mainly for drugs, systemic infection, local infection, trauma, and alcohol-related reasons. Now that most people in New South Wales have been vaccinated against COVID-19, a further study is needed to quantify the effect of the pandemic on patients with SUD in the post-vaccine era.
