21.1

Controlled Substance Handling Follows a Defined Diversion Control Plan

Non-Negotiable

Storage, dispensing, and any take-home provision of controlled medications used in addiction treatment follows a specific, written diversion control plan — secure storage, dispensing records, identifiable take-home packaging — not general good practice without a defined, documented plan.

In plain terms: Methadone, buprenorphine, and other controlled medicines in addiction treatment are stored, dispensed, and taken home under a written plan that prevents diversion — with records that account for every dose.

Facility category	Crisis	Transition	Small	Standard
Applicability	N/A	Full	Full	Full

Why this matters

Opioid agonist treatment saves lives — and its medicines have street value. Diversion harms the patient who is not taking their dose, the person who buys it, and the programme whose credibility depends on control. A diversion control plan specifies: secure storage with restricted access and a register; supervised consumption for new and unstable patients; take-home eligibility criteria; random callbacks for take-home patients to count remaining doses; urine testing; reconciliation of stock against dispensing daily. Any discrepancy is investigated. A programme without this is a supply.

What good looks like

A specific, written diversion control plan covers storage, dispensing, and take-home provision.
Take-home packaging is specifically identifiable and secure.
Patients receive genuine, documented education on safe storage and transport.

Common failure modes

No specific written plan exists beyond general good practice.
Take-home packaging isn't specifically identifiable or secure.
Patient education on storage and transport is assumed rather than genuinely provided.

Worked example

In practice

An addiction treatment clinic with 150 patients on methadone and buprenorphine.

BeforeMethadone was stored in a locked cupboard with one key held by whoever was on duty. The dispensing record was a notebook. Stock was not reconciled. Take-home doses were given by clinician discretion without written criteria. Two patients were found to be selling take-home doses; the clinic could not account for a 400 ml discrepancy in the previous quarter.

ActionA diversion control plan was written: controlled drug safe with dual-key access and a signed register; daily stock reconciliation with any discrepancy reported to the medical director within 24 hours; supervised consumption for the first 12 weeks and for any patient with positive urine screens; written take-home criteria (stability, negative screens, safe storage confirmed); random callbacks for 10% of take-home patients monthly; a dispensing record with two signatures per dose.

AfterThe Monitor inspected the safe and register, reviewed three months of daily reconciliations with no unexplained discrepancy, reviewed take-home criteria applied in 15 records, and callback records. Verified.

If you are starting from zero — do this first

Reconcile your controlled drug stock today against your dispensing records. Does it balance?
Install dual-key access and a signed register.
Write take-home criteria and supervised consumption rules.
Start random callbacks.

The most common mistake: Storing methadone in a cupboard with a shared key and a notebook — that is not control, it is trust.

Self-assessment questions

1. Is there a specific, written diversion control plan covering storage, dispensing, and take-home provision? — A specific, documented plan, not general good practice assumed to be sufficient.
Evidence: Diversion control plan document

2. Is take-home medication packaged and labeled in a way specifically designed to identify it and deter diversion? — Specific, identifiable packaging, not standard containers without distinguishing features.
Evidence: Take-home packaging protocol

3. Do patients receiving take-home medication receive specific education on safe storage and transport, including household safety? — Genuine, documented education, not assumed common sense.
Evidence: Patient education documentation

Common reasons for a PARTIAL answer

Storage security is strong but dispensing records aren't consistently reconciled against inventory. — Diversion can occur at the dispensing stage even when storage itself is secure.
Take-home packaging is used but doesn't consistently include identifying information. — Identifiable packaging is specifically what allows recovery or accountability if diversion is suspected.
Education happens for new patients but isn't reinforced for those on long-term take-home regimens.

Implementation plan

When	What
Week 1	Review current controlled substance handling against a specific, written diversion control plan standard.
Week 2	Establish or strengthen identifiable, secure take-home packaging.
Week 3	Establish genuine, documented patient education on safe storage and transport.
Ongoing	Reconcile dispensing records against inventory regularly.

How the Monitor verifies this

Method	What	Detail
DOCUMENT	Diversion control plan review	Reviews the written diversion control plan for specificity and completeness.
OBSERVE	Take-home packaging check	Confirms take-home medication packaging is specifically identifiable and secure.
DOCUMENT	Patient education review	Reviews documentation of specific patient education on safe storage and transport.

Supervisor tips

Ask for the actual written diversion control plan, not a general description of careful handling. — A specific, written document is the real evidence of a genuine plan.
Ask a patient receiving take-home medication what storage guidance they were given. — This reveals whether education is genuine practice, not just assumed to have happened.

Evidence base

[92] Established regulatory principles for medications used in the treatment of opioid use disorder, recognized in various forms across many countries, require a written diversion control plan, secure and identifiable take-home medication packaging, and patient education on safe storage and transport.

21.2

Withdrawal Management Uses a Validated Assessment Scale, Not Clinical Impression Alone

Non-Negotiable

Withdrawal severity is assessed using a validated, standardised scale, applied consistently and at defined intervals, with the result actively guiding the management decision — not estimated from clinical impression without a structured, repeatable tool.

In plain terms: Withdrawal severity is measured with a validated scale (COWS for opioids, CIWA-Ar for alcohol) at set intervals, and the score — not the clinician's impression — drives treatment.

Facility category	Crisis	Transition	Small	Standard
Applicability	N/A	Full	Full	Full

Why this matters

Alcohol withdrawal untreated progresses to seizures and delirium tremens, which kills. Opioid withdrawal undertreated drives patients back to using. Clinical impression underestimates both: the patient who 'seems fine' is sweating and tremulous on examination. Validated scales — CIWA-Ar for alcohol, COWS for opioids — give a number that maps to a treatment: below X, observe; X to Y, symptomatic medication; above Y, start the protocol. Scored at defined intervals, the trend shows whether treatment is working. A programme that manages withdrawal by impression will miss the patient heading for a seizure.

What good looks like

A validated scale is used consistently for every applicable patient.
Assessment happens at defined, scheduled intervals.
Management decisions are genuinely and documentably linked to the score.

Common failure modes

Withdrawal severity is estimated from clinical impression without a structured tool.
Assessment happens only reactively, when a concern arises.
Scores are recorded but don't genuinely drive the management decision made.

Worked example

In practice

An outpatient addiction clinic managing alcohol and opioid withdrawal.

BeforeWithdrawal was assessed by asking the patient how they felt. Medication was given 'as needed.' A patient in alcohol withdrawal was sent home as 'mild' and had a seizure that night. No scale was used; no score was documented.

ActionCIWA-Ar and COWS were adopted, administered by trained nurses at every visit and at defined intervals during medically managed withdrawal (e.g. CIWA every 4 hours for outpatient alcohol detox with a home carer). Treatment protocols are triggered by score: CIWA ≥10 → benzodiazepine per protocol; ≥20 or seizure history → inpatient referral. Scores are charted to show trend. Nurses completed a half-day training on scale administration.

AfterThe Monitor reviewed 20 withdrawal management records with scored assessments at protocol intervals and score-driven treatment; two showed inpatient referral for high scores. Training records complete. Verified.

If you are starting from zero — do this first

Pull ten withdrawal records: is a validated scale scored? How often?
Adopt CIWA-Ar and COWS and train nurses to administer them.
Write treatment thresholds by score.
Chart scores to show trend.

The most common mistake: Managing alcohol withdrawal on how the patient looks — the seizure comes when they looked fine an hour ago.

Self-assessment questions

1. Is a validated, standardised withdrawal assessment scale used consistently, not clinical impression alone? — A specific, validated tool, applied the same way every time.
Evidence: Withdrawal assessment scale documentation

2. Is the scale applied at defined intervals appropriate to the withdrawal risk, not only when a concern happens to arise? — A specific, scheduled interval, not reactive assessment alone.
Evidence: Assessment interval protocol

3. Does the scale result actually guide the management decision, not just get recorded alongside a separately made clinical decision? — Genuine, documented linkage between score and decision, not parallel, disconnected processes.
Evidence: Score-to-decision linkage record

Common reasons for a PARTIAL answer

The scale is used consistently during standard hours but less consistently during off-hours coverage. — Withdrawal risk doesn't diminish outside standard operating hours.
Assessment intervals are followed initially but relax as a patient's condition appears to stabilise. — Early stabilisation doesn't eliminate the value of continued, consistent monitoring.
The score is calculated correctly but the specific threshold for changing management isn't clearly defined.

Implementation plan

When	What
Week 1	Review current withdrawal assessment practice for validated scale use versus clinical impression alone.
Week 2	Establish or reinforce a defined assessment interval schedule.
Week 3	Define clear thresholds linking specific scores to specific management decisions.
Ongoing	Audit consistency of scale use across all coverage periods, including off-hours.

How the Monitor verifies this

Method	What	Detail
DOCUMENT	Assessment scale review	Reviews the specific validated scale used and confirms consistent application.
DOCUMENT	Assessment interval review	Reviews the defined interval schedule for withdrawal assessment.
DOCUMENT	Score-to-decision review	Reviews whether management decisions are genuinely linked to the assessment score.

Supervisor tips

Ask staff working off-hours or covering shifts specifically about assessment practice. — This is where consistency most commonly relaxes relative to standard hours.
Ask for a specific example of a score change leading to a specific management change. — A real example reveals whether the score genuinely drives decisions, not just gets recorded.

21.3

Urine Drug Screening Chain of Custody Prevents Tampering

Core

Urine drug screening follows a defined chain-of-custody process — specimen temperature verification, direct observation where clinically indicated, secure transport — that genuinely prevents substitution or tampering, not a process that assumes good faith without verification.

In plain terms: Urine drug tests are collected and handled in a way that stops substitution and tampering — temperature checked, observed when necessary, sealed and tracked — so results can be trusted.

Facility category	Crisis	Transition	Small	Standard
Applicability	N/A	Full	Full	Full

Why this matters

A urine drug screen guides take-home decisions, treatment adjustments, and sometimes legal consequences. A sample that was substituted with a friend's urine, diluted with tap water, or swapped in transit is worse than no sample: it produces a confident wrong answer. Chain of custody means: identity verified; temperature checked within four minutes (32–38°C); observed collection where clinically indicated and with dignity safeguards; sample sealed in the patient's presence and initialled; a log from collection to result. This protects the patient from false accusations as much as it protects the programme from manipulation.

What good looks like

Specimen temperature is verified and documented immediately after collection.
Direct observation follows a specific, defined standard, applied consistently.
Chain of custody is genuinely unbroken and documented, with any gap specifically flagged.

Common failure modes

Temperature verification doesn't happen or isn't documented.
Direct observation is applied inconsistently without a clear standard.
Chain of custody has undocumented gaps or is assumed intact without verification.

Worked example

In practice

An addiction clinic using urine screens to decide take-home eligibility.

BeforePatients were given a cup and pointed to the toilet. No temperature check. No observation. Samples sat unlabelled on a bench until batched. A patient obtained take-home doses for a year on consistently clean screens that were later found to be his partner's urine.

ActionA chain-of-custody procedure was written: two-identifier check; temperature strip read within four minutes with out-of-range samples rejected; observed collection for patients with prior tampering, new admissions, or clinical concern, by a same-gender staff member with a written dignity protocol; sample sealed and initialled by patient and staff at the point of collection; a custody log from collection to result. Adulteration testing added to the lab panel.

AfterThe Monitor observed a collection following the procedure, reviewed the custody log for 50 samples, and reviewed the observed-collection protocol. Verified.

If you are starting from zero — do this first

Watch a urine collection. Is temperature checked? Is the sample sealed in front of the patient?
Buy temperature strips and reject out-of-range samples.
Write criteria for observed collection with a dignity protocol.
Start a custody log.

The most common mistake: Trusting a clean screen without knowing the sample was the patient's — a clean screen from someone else's bladder is a false negative.

Self-assessment questions

1. Is specimen temperature verified immediately after collection, as a specific, documented step? — A specific, documented check, not assumed from general collection procedure.
Evidence: Temperature verification record

2. Is direct observation used where clinically indicated, following a specific, defined standard for when it applies? — A specific standard for when observation is used, not inconsistent, ad hoc application.
Evidence: Direct observation policy

3. Is chain of custody maintained and documented from collection through to result, with any break specifically flagged? — A genuinely unbroken, documented chain, with any gap specifically identified, not assumed intact.
Evidence: Chain of custody documentation

Common reasons for a PARTIAL answer

Temperature verification happens but isn't consistently documented in the specimen record. — An undocumented check is difficult to distinguish from a check that didn't happen.
Direct observation criteria exist but aren't consistently applied by all staff collecting specimens. — A standard needs consistent application across everyone performing collection to provide real protection.
Chain of custody documentation exists but has occasional gaps during transport to an external lab.

Implementation plan

When	What
Week 1	Review current specimen collection practice for temperature verification and documentation.
Week 2	Establish or reinforce a specific, consistently applied direct observation standard.
Week 3	Close any gap in chain-of-custody documentation, particularly during external transport.
Ongoing	Audit chain-of-custody documentation for completeness periodically.

How the Monitor verifies this

Method	What	Detail
DOCUMENT	Temperature verification review	Reviews records confirming specimen temperature is verified immediately after collection.
DOCUMENT	Direct observation policy review	Reviews the specific standard for when direct observation is clinically indicated and applied.
DOCUMENT	Chain of custody review	Reviews documentation for a genuinely unbroken chain of custody from collection to result.

Supervisor tips

Ask to see the actual temperature verification and chain-of-custody documentation for a recent specimen. — Specific, dated records are the only real evidence of a genuinely functioning process.
Ask staff the specific criteria for when direct observation is used. — A specific, consistent answer reveals a genuine standard rather than inconsistent individual judgement.

Evidence base

[94] Specimen temperature verification and defined chain-of-custody procedures are established practice for preventing urine drug screening substitution and tampering in addiction treatment settings.
