PRESCRIPTION OPIATE RISK TOOL (PORT) Developed by
Algosresearch
Based on the latest research (BMC Health Serv Res. 2006 Apr 4;6(1):46) and prior
attempts to define risk of prescription abuse or aberrant behavior in a pain clinic
setting, the following point scale has been defined to assist the physician to
preemptively  detect and monitor patients at risk.  Behaviors that are considered
aberrant are only valid if the patient has knowledge of expectations of the physician
and therefore a printed list of aberrant behaviors that must be avoided must be
available to the patient before prescribing opiates.  This is often in the form of a
narcotic agreement or contract.
Aberrant Behaviors Unacceptable in Pain Management:
1. Use of illicit drugs while receiving opiates
2. Use of alcohol while receiving opiates
3. DUI or arrest for drug diversion
4. Selling or giving away narcotics to anyone, even family members
5. Receiving narcotics from anyone else other than the pain clinic unless there is an
acute need for physician prescribed narcotics, and the patient agrees to contact the
pain clinic within 72 hours with this information.
6. Overuse of prescribed medications or use in a manner not prescribed

20 or higher: These are patients considered to have too high of a risk for treatment in
most pain clinics.  
Unless the pain clinic has a certified addictionologist on staff, it is
suggested these patients be referred to a comprehensive university pain clinic, no matter how
far away.  Typically these patients engage in substance abuse or diversion within the first 2
months of treatment in a typical pain clinic.

15 or higher= Very High Risk of Substance Abuse in the next year.  It is suggested these patients
have very close follow-up with mandatory psychology program participation, never greater than 1 month
intervals on follow up, and no multi-month (eg refills on schedule III meds or 3 month mail in scripts)
prescriptions.  Urine drug screens should be conducted routinely and pill counts should be conducted
randomly by the patient's pharmacist or by the clinic staff.  Initial visits should be 1-2 week intervals.  
Extremely high vigilance is necessary.  Tight control on the amount of narcotics prescribed and on the
patient use of the narcotic is necessary.  Do not escalate dosages of narcotics...these patients are on
long term maintenance therapy and should not be permitted any latitude in their use of the narcotics.

10-14= High risk of substance abuse.  Precautions should be taken with appropriate intensified
monitoring, definitely with random drug screening, and interval of follow-up visits should be no more than
one month.  High level of suspicion regarding any unusual occurrences surrounding prescription
narcotics.

7-10= Moderate risk of substance abuse  Cautious implementation of longer follow-up intervals.

6 or less=Low risk of substance abuse   Only occasional random drug screens needed.  After the
first 3 months of monthly follow-up visits, the intervals of follow-up visits may be increased, but never to
more than 3 months when long acting opiates or significant quantities of short acting schedule II or III
drugs are being prescribed.  If there are any aberrations after initiation of therapy, re-assess the
potential for substance abuse and decrease the intervals between follow up visits.
