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)

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]

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

Thanks – any questions?
