Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients are referred to this outpatient alcohol and drug service following inpatient hospital admission, by their General Practitioner, or self-referral. Initial assessment is conducted by a clinical nurse or social worker. Initial assessment includes standardised review of psychosocial history, dependency symptoms, dependence severity, and comorbid drug use. Suitable patients are enrolled in the Cognitive-Behavioural Therapy (CBT) for Alcohol Use Disorder (AUD) program. When enrolled in the program patients receive a 1-hour consult with an addiction specialist physician, comprising a medical review, physical examination, assessment of suitability for prescription of adjunct pharmacotherapy (e.g. Acamprosate or naltrexone), and a written report to their primary health-care provider with recommendations for ongoing management. The CBT for AUD program comprises 8x 1hour face-to-face outpatient sessions over 3 months with a clinical psychologist. Following three months of abstinence, less frequent contact is maintained. Breathalyser readings are mandatory and routinely undertaken prior to each session. Standardised assessments are administered each session, monitoring: drinking behaviours (quantity, frequency), adherence to adjunct pharmacotherapy, alcohol craving, and alcohol refusal self-efficacy. The first session is devoted to obtaining a thorough assessment of the problem (including a comprehensive psychometric battery), education about the potential harms associated with alcohol, and affirming commitment to alcohol abstinence for the duration of the program. A CBT intervention plan is then developed collaboratively based on individual needs. The most common targets for intervention include: identification and alteration of alcohol expectancies, enhancement of drinking refusal self-efficacy, craving management, development of alternative coping strategies, problem-solving skills training, goal setting, and lifestyle improvement.

The Tailored Alcoholic Hepatitis (AH) Intervention will match for the existing generic face-to-face CBT Intervention historical benchmark for length of treatment (3 months) and therapist contact (8 hours). When possible, AH patients will be assessed as inpatients, including 1x addiction specialist physician assessment and 1x clinical psychologist review. The clinical psychologist will outline the services available to the patient, offering the CBT for AUD program as a means of ongoing support as an outpatient. Hospital discharge is determined by the treating medical team, not this service.

Post-inpatient hospital discharge, patients will either enrol in The CBT for AUD program or receive 2 x weekly 20 min ‘booster’ telephone sessions for 3 months (totalling 8 hours). The mode of treatment delivery (face-to-face or telephone) will be determined by geographical feasibility. Face-to-face sessions are preferred. Psychometric assessment and intervention targets will not be affected by modality, though AH patients are likely to require greater emphasis on health and lifestyle factors associated with adherence to treatment for AH. Treatment adherence is determined by session attendance, psychometric assessment at each session, and patient self-report of drinking behaviour.

This study is a non-randomised trial. All patients will receive the intervention. All patients enrolled in the CBT for AUD program consent for their anonymous data to be used for program evaluation. Non-consenting patients will not be included in the dataset but will receive the intervention. Participation is voluntary and patients may withdraw a any time without penalty. Patients who do not achieve abstinence will be offered ongoing support or referral options appropriate to their condition and circumstances. Patient outcomes post the 3-month treatment period will not be included in this study.

Comparator / control treatment
Historical control of AH patients referred to the Cognitive-Behavioural Therapy (CBT) program for Alcohol Use Disorder (AUD; Treatment as Usual, TAU) from 01/01/2012 to 01/01/2019. TAU is not manualised or based on specific guidelines. Clinical psychologists are trained in administration of CBT for AUD.

Outcomes
Primary outcome [1] 319741 0
Patient retention as determined by the percentage of patients engaged in treatment at each time point.
Timepoint [1] 319741 0
Each of 8 sessions across 12-week intervention. Time points are non-standard, though will typically occur at 7-14 day intervals.
Secondary outcome [1] 369360 0
Percentage of days alcohol is consumed between sessions. Drinking days are determined by a Time-Line Follow Back procedure conducted by psychologists during each session.
Timepoint [1] 369360 0
Each of 8 sessions across 12-week intervention. Time points are non-standard, though will typically occur at 7-14 day intervals.
Secondary outcome [2] 370317 0
Patient engagement as determined by the proportion of patients offered the CBT for AUD program who commence treatment relative to those who do not.
Timepoint [2] 370317 0
Timepoint 1: Pre-treatment assessment.
Timepoint 2: Session 1.
Time between pre-treatment assessment and session 1 is non-standard.

Eligibility
Key inclusion criteria
All Alcoholic Hepatitis (AH) patients will be diagnosed and medically managed by liver disease specialists (Hepatologists) and Addiction specialist. Liver biopsy remains the gold standard for diagnosis, however indications for physician practice varies. While biopsy is the preferred inclusion criterion, absence will not be an exclusion criterion. For patients without liver biopsy, inclusion requires 1). Consistent alcohol risk history, 2). Absence of other acute liver injury risk; 3) at least 2/3 of: jaundice < 8 weeks, AST/ALT ratio > 2; neutrophilia. Further characterised on AH severity (Maddrey Discriminant Function 32) and the presence of cirrhosis.

Key exclusion criteria
As this is an effectiveness study all patients eligible for enrolment in the hospital based program will be included. Such eligibility requires patients to be able to provide written informed consent.

Statistical methods / analysis
The primary outcome will be assessed via logistic regression, where the outcome is completed treatment (0 = no, 1 = yes) and the independent variable is treatment group (0 = old protocol, 1 = new protocol). Potential confounding variables will be included as covariates (e.g. dependence severity). Depending on the distribution of the number of sessions attended, parametric or non-parametric statistics may be employed to determine whether more sessions were attended on average. Again, potential confounding variables will be included as covariates. Analysis of secondary secondary outcomes (drinking behaviour) will be analysed using non-parametric longitudinal mixed effects models (Multilevel Modelling). LME models are considered the gold standard in psychotherapy research as they have the advantage of modelling the trajectory of longitudinal outcomes. Missing data may therefore be imputed based on individual trajectories.

To determine non-inferiority or superiority of the new treatment protocol when the primary outcome is patient retention non-inferiority requirements were calculated in R version 3.5.0. Holding power level at 80% and alpha at 0.05, with a present response rate for patients with AH completing treatment at 30% and a modest protocol goal of 40%, a sample size of 70 patients is required to support non-inferiority within a 10% equivalence margin. Given that we have historical data for N ~130 patients, we only require 35 (70 / 2 = 35) patients to commence the new protocol for this study to be sufficiently powered.
