Brief summary
Hepatitis C virus (HCV) disproportionally affects certain populations, including those facing substance use and mental health challenges. In the past, many individuals with mental illness were not treated due to the psychiatric side-effects of interferon. However, the development of highly effective, direct-acting antivirals (DAA) has revolutionized HCV treatment such that cure rates are \>95% with 8-12 weeks of simple, safe, and well-tolerated therapy. A recent systematic review reported that across 13 North American studies, HCV prevalence among people admitted to psychiatric hospitals was a staggering 17.4% (13.2-22.6%). Despite these concerning figures, mental health facilities have not been a focus of HCV elimination efforts to date. The Centre for Addiction and Mental Health (CAMH) in Toronto is the largest mental health facility in Canada, with a psychiatric emergency department seeing \ 35 patients per day with many admitted to the acute psychiatric units for safety and stabilization. Currently, psychiatric patients screened for HCV at CAMH have a 75% 'no show' rate at the Toronto Centre for Liver Disease (TCLD), which is located less than 5km away, suggesting that referral upon discharge is ineffective. This study will be the first trial to evaluate whether it would be feasible and beneficial to initiate treatment during an acute psychiatric admission rather than referring to specialty upon discharge. The combination of broad HCV screening with rapid linkage to treatment has led to successful elimination of HCV within defined populations, so-called micro-elimination. The investigators hypothesize that HCV treatment can be effectively delivered by providers in psychiatric care facilities, which will improve treatment uptake over traditional referral models.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| SVR12 by intention to treat (ITT) in each arm | 24 months | To determine whether screening for HCV using rapid diagnostics during an acute psychiatric admission with inpatient initiation of HCV treatment is superior to standard post-discharge referral and treatment by intention to treat (ITT). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| HCV relapse rate | 24 months | To compare the HCV viral relapse rate in both arms (re-appearance of HCV RNA in those undetectable at end of treatment; relapse distinguished from reinfection by sequencing of the recurrent HCV RNA and comparing to baseline). |
| HCV seroprevalence rates | 12 months | To determine HCV seroprevalence rates among acute vs addictions patients admitted to CAMH. |
| SVR12 by modified intention to treat (mITT) in each arm | 24 months | To determine whether screening for HCV using rapid diagnostics during an acute psychiatric admission with inpatient initiation of HCV treatment is superior to standard post-discharge referral and treatment by modified intention to treat (mITT). |
| CAMH staff acceptability of POC antibody and RNA testing | 12 months | CAMH staff involved in the trial will be asked to particiapte in an acceptibility survey regarding rapid POC antibody and RNA testing on the acute units. |
| Concordance of POC HCV RNA with HCV RNA by phlebotomy | 12 months | To determine concordance of POC HCV RNA (GeneXpert) with HCV RNA by phlebotomy (Abbott RealTime). |
| HCV RNA positivity rates | 12 months | To determine HCV RNA positivity rates among acute vs addictions patients admitted to CAMH. |
| Adherence with out-patient follow-up visits | 24 months. | Evaluate and compare out-patient follow-up visit adherence in both arms. |
| Adherence to HCV treatment, by HCV regimen | 24 months. | Evaluate and compare both arms for medication adherence (patient self-report and pill count), and variance by medication regimen. |
| Adverse events while on HCV treatment | 18 months. | To determine and compare adverse events in both arms while patients are on treatment. |
| HCV Reinfection | 24 months. | Reinfection rates by the end of the defined as HCV RNA detectability after prior SVR with demonstration of distinct viral sequence from baseline sample to distinguish |
| Minimum and mean times from diagnosis to treatment initiation | 24 months | Evaluate the mean and minimum times to treatment initiation in both arms, and compare. |
