Introduction
• Island community
• Illicit drugs are difficult to import and
expensive
• Drug users look to alternative substances
mainly pharmaceuticals
• Implications for local prescribers, treatment,
prognosis and prevention
Clinical picture in Guernsey
• Very different to UK experience
• Anecdotally, little heroin, poor quality.
• Pharmaceuticals esp fentanyl and benzos
misused and implicated in ODs & deaths
• Fentanyl patches ut into strips and cooked up
• Extracted and injected
• Street value £200-300 for 100mcg patch
• Pre-filled syringes available
• Suboxone street value £10/mg (vs £1/mg UK)

Drug treatment in Guernsey

CDAT: NTA tier 2-3; no T4 on island
Charity NTA T1 + NEX
AA active; no NA
OST options are mainly DF-118 (high dose) and
Subuxone > Subutex
Methadone not approved
“NHS” (Mental health, addictions, infectious diseases,
radiology, pathology)
Medical Specialists Group (chambers): all other
secondary care
Primary Care is private
All 3 different systems – including data systems!
Methodology
• 3 Audit results examined:
– Unnatural deaths (2002-2011) [States Pathologist]
– Substances misused from CDAT referrals (2011-13)
– Prescribing data [Prescribing Advisor]
Results (1):Unnatural deaths

Different drug death profiles
•
•
•
•
•
•
•
Higher proportion of fentanyl, benzo deaths
Fentanyl = Heroin (14%) < Heroin E&W (30%)
DHC/Codeine 17% vs E&W 2%
Methadone 4% vs E&W 12%
Paracetamol 4% vs E&W 11%
Guernsey: no cocaine, amphetamine deaths
BUT: small Guernsey numbers (n=106) vs E&W
(27k)
Results (2)
• 280 drug patients were referred/3 yrs
• Buprenorphine (36%), benzodiazepines (30%),
dihydrocodeine (18%), fentanyl (9%), heroin (7%)
and codeine (7%)
• 90%+ misusing prescription only medicines
(POMs) and over the counter (OTC) drugs,
particularly opiates and benzodiazepines
• Reported patterns of use tended to follow local
availability and poly-drug misuse was common

Implications
• Drug users are creative and will find
alternative substances and ways of using them
• Fentanyl-related deaths = heroin-related
deaths at post mortem/case review
• A high risk sub-group of substance misusers
(9%) injecting fentanyl (derived from fentanyl
patches) was identified
• How to address fentanyl and POM availability?
Action Plan
• Discussed with service users, Public Health,
Drug & Alcohol Team, and Drug & Alcohol
Strategy Co-ordinator in 2011
• Suggested a forum be set up to raise concerns,
share info, monitor trends, discuss strategies
to address POM availability
Addictive POM Group
• Public Health, CDAT, Border Agency, Primary Care,
Pain Clinic, Prison HC
Action Plan (2)
•
•
•
•
APOM group met first in 2011 quarterly
Prescribing advisor showed fentanyl px data
Opioid px audit: Primary Care & Pain Clinic
Border agency: aware to look for APOM
imports – changed policy (personal use) and
several arrests
• Prenoxad programme for high risk injectors

Results (2): changes in prescribing
•
•
•
•
•
•
•
Over 2011 to 2013:
Fentanyl prescribing ↓ by 18% and cost ↓ by 45%
Sedative hypnotics ↓ by 13%
Morphine increased…
Oxycodone and Tramadol increased…
Increased awareness among prescribers
Support for various initiatives incl Community
Supervised Consumption, GP shared care
• Annual audit of drugs misused at referral to
continue
Discussion (1)
• High rates of pharmaceutical drug misuse
• May reflect the low availability of illicit drugs:
displacement
• Increases demand for addictive POMs and OTCs.
• Prescribers in isolated communities need to be
more cautious when prescribing addictive POMs
• Pharmacists and Prescribing Advisors may need
to monitor for POM and OTC drug misuse
particularly of opioid-containing medications and
benzos
• Ongoing data monitoring may be helpful
Discussion (2)
• Generalizeable?
• Island, small area, homogeneous population
• Possible to capture almost all of the people
referred for help with substance misuse
• Whether that would translate to big cities is
hard to know. But for other smaller
communities, may give insights into the
problem and possible solutions
Discussion (3)
•
•
•
•

•
•
Future?
Ongoing data monitoring
Cross reference with Drug Testing results
…and Prescribing data (2013-)
…and Unnatural Death data (2012-)
…wider than fentanyl: benzos, DHC
Watch Buprenorphine referrals and as Community
Supervised Consumption was strengthened in 2014
• Watch if new pain meds appear in referrals
• #1 drug cause of death though = alcohol!
Conclusions
•
•
•
•
•
Creative drug users
Demand high – why?
Supply restriction: borders vs prescribers
Prescribing responsibility: wider than patient
Addictive POM group: co-ordinated approach
may reduce prescribed drugs and hence drug
availability – public health initiative
• Questions? Ideas & research links welcome!
Thanks – any questions?
