This page provides a transparent overview of how Siam Rehab operates as a licensed private residential addiction treatment facility in Chiang Rai, Thailand. It covers legal status and medical licensing under the Thai Ministry of Public Health, screening and detox triage protocols, psychiatric and nursing oversight, staff credentials and ratios, emergency and hospital transfer procedures, program structure, aftercare pathways, and aggregated outcomes for clients treated between 2022 and 2025.
Clinical governance at Siam Rehab accounts for the progressive nature of substance-related risk by aligning assessment, monitoring, and escalation thresholds with evidence-based understanding of neurobiological adaptation and behavioral reinforcement patterns, rather than treating substance use as static or binary.
1. Legal Status, Licensing, and Accreditation
Siam Rehab operates as a private residential rehabilitation facility under the legal entity Can Siam Co., Ltd., registered in Chiang Rai, Thailand. The facility is licensed by the Thai Ministry of Public Health through the Chiang Rai Provincial Health Office as a substance abuse treatment clinic and residential rehabilitation facility, with authority to provide medically supervised detoxification, individual and group counselling, residential rehabilitation, psychiatric evaluation, and psychosocial support services. The current license is valid through 8 September 2026.
The facility has undergone national Healthcare Accreditation (HA) assessment under the MoPH/PMNIDAT regulatory framework and maintains compliance with national standards for residential rehabilitation. Accreditation status is subject to periodic review within the national HA cycle.
2. Medical and Psychiatric Oversight
Medical oversight is provided by Dr. Nattapatt Sukkhosawat (Medical Council of Thailand License No. 155270), Consulting Psychiatrist and Medical Director. Regular on-site psychiatric clinics are conducted seven days per week, with on-call availability for urgent clinical review. The psychiatrist oversees all psychiatric evaluations at or shortly after admission and ongoing medication management for co-occurring mental health conditions.
Nursing care is delivered by registered Thai nurses experienced in addiction and detoxification settings. Nurses conduct scheduled vital sign monitoring, administer prescribed medications per documented protocols, and maintain structured medication administration records. All psychiatric and nursing practice adheres to Ministry of Public Health clinical guidelines.
Standardized screening instruments are employed for risk assessment and clinical monitoring, including CIWA-Ar (alcohol withdrawal), COWS (opioid withdrawal), PHQ-9 (depression), and GAD-7 (anxiety). Results inform risk stratification and treatment planning.
3. Screening, Admission, and Detox Triage
Pre-admission screening includes structured review of medical and psychiatric history, substance use patterns, current medications, allergies, recent hospitalizations, and risk indicators such as prior severe withdrawal, seizures, self-harm, or psychosis. This assessment determines suitability for direct residential admission or requirement for hospital-based stabilization prior to transfer.
Clients are stratified into low, moderate, or high medical risk categories based on standardized tool results and clinical judgment. Exclusion criteria for direct residential admission include unstable cardiovascular, hepatic, or renal conditions; severe withdrawal requiring intensive care; active psychosis; active suicidal behavior; pregnancy (case-dependent review); and unwillingness to taper high-dose maintenance therapy.
For clients approved for on-site detoxification, monitoring follows a structured 72-hour observation protocol with regular vital sign checks, symptom documentation using CIWA-Ar or COWS as indicated, and administration of comfort medications per medical order. Any clinical deterioration triggers immediate escalation to the psychiatrist and potential hospital transfer.
4. Emergency Response and Hospital Transfer
Siam Rehab maintains a written emergency response protocol covering medical, psychiatric, environmental, and security incidents. Staff are trained to recognize early warning signs and activate response procedures without delay. Emergency equipment includes oxygen supply, first-aid kits, automated external defibrillator (AED), and basic monitoring devices.
In emergencies, staff prioritize immediate safety, initiate basic life support measures as indicated, and activate the national emergency medical services system via 1669. Emergency transfers are directed to Mae Chan Hospital, approximately 22 km from the facility. Non-emergency referrals for specialist review or planned stabilization are coordinated with Kasemrad Sriburin Hospital, Chiang Rai.
All transfers are documented with clinical summary, informed consent records, and hospital discharge information to ensure continuity of care.
5. Staff Credentials, Roles, and Ratios
The clinical team comprises a psychiatrist serving as Medical Director, psychologists, addiction counsellors, registered nurses, and supporting roles including fitness, yoga, meditation, and massage instructors. Counsellors hold recognized qualifications in addiction or mental health fields; psychologists hold relevant degrees; all clinical licenses are verified and maintained on file.
Client capacity is capped at 18 residents to preserve therapeutic intensity. Counselor-to-client ratio is maintained at approximately 1:4–5. Including clinical, nursing, and support staff, the overall staff-to-client ratio approximates 1:1.3.
Clinical governance includes weekly internal supervision, external supervision for counsellors, and continuing professional development requirements for all clinical staff. Performance reviews and license verifications are conducted periodically.
6. Program Structure and Therapeutic Model
The residential program follows a non-12-step, abstinence-based framework with individualized treatment planning and a structured daily Active Recovery Model. Core therapeutic modalities include Cognitive Behavioral Therapy (CBT), Motivational Interviewing (MI), Dialectical Behavior Therapy (DBT), Relapse Prevention Therapy, Rational Emotive Behavior Therapy (REBT), psychoeducation, and structured group therapy. Medication-assisted detoxification is provided when clinically indicated. Clients receive a minimum of two individual therapy sessions per week.
The weekly schedule maintains consistency with a balance of group therapy, individual sessions, psychoeducation, structured physical activity, and dedicated reflection periods. Clients undergoing detoxification follow a modified schedule during stabilization.
Complementary components (Muay Thai non-contact training, yoga, meditation, massage therapy, fitness training) are offered as adjuncts to, not replacements for, evidence-based psychotherapy and medical care. Facilities include private en-suite rooms, group therapy rooms, gym, swimming pool, and outdoor spaces, positioned as structured residential infrastructure.
7. Aftercare and Continuity of Support
Siam Rehab provides a structured 12-week aftercare program to support clients during early recovery post-discharge. Contact frequency follows a tapering schedule: weekly check-ins during weeks 1–4, biweekly during weeks 5–8, and monthly during weeks 9–12. Modalities include phone, video, and secure messaging as clinically appropriate.
Aftercare focuses on relapse-risk management, routine reinforcement, lifestyle planning, stress regulation, and support for emerging challenges in relationships, occupation, or health. Where indicated, clients are referred to community-based options such as SMART Recovery, Recovery Dharma, or local outpatient services.
Aftercare also facilitates voluntary follow-up data collection on substance use, mental health status, functioning, and satisfaction, contributing to longitudinal outcome monitoring.
8. Outcomes (2022–2025)
Siam Rehab systematically tracks client outcomes using validated instruments and standard rating scales. Between 2022 and 2025, anonymized aggregate data were analyzed from 250 clients representing 24 countries who completed the residential program. Measures included PHQ-9 (depression), GAD-7 (anxiety), craving levels, sleep quality, wellbeing indices, satisfaction ratings, therapeutic alliance, and Net Promoter Score (NPS).

Methodological Clarification
These data derive from internal observational follow-up reporting. The design is non-randomized, without a control group. Participation in outcomes monitoring is voluntary; follow-up response rates are not 100%, introducing potential attrition bias. Results represent aggregate trends and are not predictive of individual outcomes. Limitations are acknowledged in clinical interpretation and program refinement.
9. Data Protection, Ethics, and Interpretation
All outcome data collection and analysis at Siam Rehab prioritize client safety, confidentiality, and ethical standards. Clients provide explicit informed consent for anonymized, aggregate use of their information. Participation in outcomes monitoring is voluntary and does not influence access to or quality of care.
Data are stored securely, accessed only by authorized clinical personnel, and analyzed exclusively in aggregate form. Validated instruments and consistent internal definitions guide interpretation. Limitations—including follow-up response rates, absence of a control group, and observational design—are explicitly acknowledged.
Outcome reporting is intended to provide transparent, clinically honest information for program evaluation and improvement. Published results do not constitute guarantees of individual treatment outcomes.
