Overview

• Opiate and benzodiazepine use in individuals in methadone programs

– With overdose deaths from heroin and prescription pain medications increasing in the U.S., opioid addiction is an important concern for Medicaid programs

– Medicaid beneficiaries have higher rates of opioid addiction than other insured groups 5© 2014 Community Care Behavioral Health Organization

Benzodiazepine Use and Misuse

• Among patients in a methadone program – BMC Psychiatry, May 2011:

– Benzodiazepines (BZD) misuse and abuse is a serious public health problem in the U.S.

– This problem is especially pertinent among those with opiate dependence because these individuals are more likely to experience elevated anxiety after stopping use of opiates

– It has been shown that individuals who abuse BZD are at increased risk of continuing opiate abuse and failing to stay in methadone treatment

Benzodiazepine Use and Misuse

• In a Baltimore methadone program:– Survey conducted at a methadone

treatment program in Baltimore– 194 questionnaires were included in the

final data analysis• 47% reported using BZD with/without

a prescription• 25% said that their initial use began with

a prescription• 54% did not start using BZD until after

entering the methadone program

Page 9: Decreasing the Use of Prescription Opiates and Benzodiazepines Among Individuals Enrolled in Methadone Programs Kim Castelnovo, RPh Pharmacy Manager, Community.

Benzodiazepine Use and Misuse

• When asked patients in a methadone program if they would consider reducing or stopping the use of BZD if the methadone program could provide help that would work:– 40% said “Yes, definitely”– 7% said “Maybe” – 19% said “No” – 33% had already stopped using BZD

Collaboration of Care Implementation Guideline

Presented by:Sara Remaley, MSPC, CAADC, Clinical Supervisor WPIC NATP

Valerie Gualazzi, MS, CADC, Program Director WPIC NATPWestern Psychiatric Institute and Clinic

Page 22: Decreasing the Use of Prescription Opiates and Benzodiazepines Among Individuals Enrolled in Methadone Programs Kim Castelnovo, RPh Pharmacy Manager, Community.

• WPIC NATP is a clinic specializing in opioid dependency in

addition to psychiatric comorbidity.

• WPIC offers methadone maintenance treamtent, suboxone

treatment, psychiatric care and medication management,

mental health, and addiction therapy.

• WPIC currently treats approximately 420 patients on a

regular basis.

Page 23: Decreasing the Use of Prescription Opiates and Benzodiazepines Among Individuals Enrolled in Methadone Programs Kim Castelnovo, RPh Pharmacy Manager, Community.

Rationale

• NATP recognized a need to address the misuse and abuse of prescription benzodiazepines by patients enrolled in medication assisted treatment.

• High rates of patients were enrolling in treatment and concurrently becoming addicted to and abusing benzodiazepines, posing health risks, adverse effects, and ultimately untimely discharge from treatment.

Page 24: Decreasing the Use of Prescription Opiates and Benzodiazepines Among Individuals Enrolled in Methadone Programs Kim Castelnovo, RPh Pharmacy Manager, Community.

Collaboration of Care

• 2012- WPIC NATP redesigned the program’s philosophy and position regarding concurrent use and abuse of prescription benzodiazepines and opiates while taking methadone.

• Contraindications and potential for adverse effects helped NATP move in the direction of ‘therapeutic no tolerance’.

• The “Collaboration of Care” Procedure : indicating NATP’s willingness to work with patients currently on prescription benzodiazepines to taper off and receive evidence based interventions and seek alternative treatment options as needed.

Page 25: Decreasing the Use of Prescription Opiates and Benzodiazepines Among Individuals Enrolled in Methadone Programs Kim Castelnovo, RPh Pharmacy Manager, Community.

Collaboration of Care

• The Collaboration of Care Procedure was developed as a way to inform patients of the new treatment philosophy indicating: use of benzodiazepines and opiates while on methadone is no longer permissible.

• With the understanding that tapering from these type of medication can be a difficult and lengthy process with potential for relapse, NATP developed a procedural guideline to assist both patients and staff through this new process.

Page 26: Decreasing the Use of Prescription Opiates and Benzodiazepines Among Individuals Enrolled in Methadone Programs Kim Castelnovo, RPh Pharmacy Manager, Community.

Page 27: Decreasing the Use of Prescription Opiates and Benzodiazepines Among Individuals Enrolled in Methadone Programs Kim Castelnovo, RPh Pharmacy Manager, Community.

• Difficult tapering process, risk related to withdrawal symptoms, and potential need for medically supervised detoxification.

• High Relapse rates with benzodiazepines.• Concurrent rates of psychiatric comorbidity and the

need to address/treat underlying mental health conditions.

• Collaborating with providers (prescribing physicians) vs. illicit street use.

• Addressing diversion…How does this fit?

Barriers to addressing bzd use:

27

Page 28: Decreasing the Use of Prescription Opiates and Benzodiazepines Among Individuals Enrolled in Methadone Programs Kim Castelnovo, RPh Pharmacy Manager, Community.

• Step 1: Staff Education– Development of Procedural Guideline highlighting

philosophy, procedures and interventions, and processes for team to follow.

• Step 2: Patient Education– An FAQ was developed and handed out to all patients

indicating the new Collaboration of Care and Program Philosophy regarding Concurrent use of benzodiazepines while in treatment.

Let the collaboration begin….

FAQ

Page 30: Decreasing the Use of Prescription Opiates and Benzodiazepines Among Individuals Enrolled in Methadone Programs Kim Castelnovo, RPh Pharmacy Manager, Community.

• Step 3: Patient Acknowledgement and Responsibilities:– Reviewing the new philosophy and Collaboration of Care with

patients, and asking them to acknowledge with their signatures that they have been informed.

– A part of this process is also to explain to patients, the risks, as well as their rights. Albeit patients may reserve the right to refuse collaboration, they are also informed how this may directly impact their ability to remain in treatment.

Page 31: Decreasing the Use of Prescription Opiates and Benzodiazepines Among Individuals Enrolled in Methadone Programs Kim Castelnovo, RPh Pharmacy Manager, Community.

• Step 4: Interventions– Once the Collaboration of Care is initiated, the following

procedures /interventions may be followed:• Urine Drug Screens and CCBHO Report reviewed.• Contact with the prescribing physician (physician to

physician) to discuss recommendations and to create a tapering regimen.

– Pill Counts

• Illicit Street Use: Assessing need for medically supervised detoxification. Resources: Mercy Hospital Emergency Room, WPIC DEC (Diagnostic Evaluation Center).

• UDS Confirmatory tests to determine if “levels” are decreasing- indicating progress/regression.

Page 32: Decreasing the Use of Prescription Opiates and Benzodiazepines Among Individuals Enrolled in Methadone Programs Kim Castelnovo, RPh Pharmacy Manager, Community.

• Interventions Continued:• Assessing underlying mental health and psychiatric disorders such

as anxiety, depression, mood disorder, bipolar disorder, etc. Choosing a modality to effectively work with and treat these disorders in addition to addiction.

– CBT, REBT, Gestalt Therapy, DBT, Motivational Interviewing, Person Centered etc.

• Modifying treatment plans: Increasing therapy, regular appointments with Psychiatrist, following a medication regimen, ongoing collaboration.

• Maintaining focus on individualized care through individualized recommendations. Assessing Progress: How is this done? Regular team meetings and supervision.

Page 33: Decreasing the Use of Prescription Opiates and Benzodiazepines Among Individuals Enrolled in Methadone Programs Kim Castelnovo, RPh Pharmacy Manager, Community.

Response to Interventions

• What happened after the Collaboration of Care was initiated?– NATP experienced responses similarly associated with the Change

Curve (Kubhler-Ross) • Shock, Denial, Anger, Acceptance, Integration

Page 34: Decreasing the Use of Prescription Opiates and Benzodiazepines Among Individuals Enrolled in Methadone Programs Kim Castelnovo, RPh Pharmacy Manager, Community.

• How long did it take before a change was noticeable?– Integration took time and CONSISTENCY IS KEY

• Response to change implementation included:– Compliance and Collaboration.– Increase in individual/group therapy- engagement in regular

psychotherapy.– Increase in psychiatric treatment and psychopharmacology.– Exacerbation of symptoms/negative behaviors.– Increase in referrals to Higher LOC’s. – Decrease in bzd rates.– Increase in compliance/privilege status.

Response to Interventions

BENZODIAZEPINES

INTERNEURONS IN THE VTA APPLY INHIBITORY EFFECTS ON DOPAMINERGIC NEURONS

THESE INHIBITORY INTERNEURONS EXERT THEIR EFFECT ON THE DOPAMINERGIC NEURONS BY WAY OF GABA (GAMMA AMINO BUTYRIC ACID)

BENZODIAZEPINES INHIBIT THIS INHIBITORY EFFECT. THIS INHIBITION RESULTS IN A MASSIVE RELEASE OF DOPAMINE FROM THE DOPAMINERGIC NEURONS.

THIS IS THE SYNERGISM WHICH OCCURS WHEN BENZODIAZEPINES ARE GIVEN WITH AN OPIOID; E.G., METHADONE.

Page 53: Decreasing the Use of Prescription Opiates and Benzodiazepines Among Individuals Enrolled in Methadone Programs Kim Castelnovo, RPh Pharmacy Manager, Community.

OPIOIDS

IN A STABILIZED METHADONE PATIENT ANY ADDITIONAL OPIOID WILL CAUSE DESTABLIZATION ;

IF THE OPIOIDS ARE TAKEN TO AN ANALGESIC LEVEL ONLY THE DESTABILIZATION WILL MAINLY AFFECT THE MEDULLA LOCUS CAERULEUS.

IF THE OPIOIDS ARE TAKEN TO THE EUPHORIC LEVEL THE DESTABILIZATION WILL AFFECT THE DOPAMINERGIC NEURONS AS WELL.

CLONIDINEIN

SEARCH OF DOPAMINE

SINCE THE OPIOID WITHDRAWAL SYNDROME IS DUE IN PART TO HYPERACTIVITY OF THE MEDULLA LOCUS CAERULEUS AND EXCESSIVE CATECHOLAMINES, A DRUG WHICH BLOCKS THIS EFFECT SHOULD TREAT THIS PART OF THE OPIOID WITHDRAWAL SYNDROME.

CLONIDINE( CATAPRESS) IS A CENTRALLY ACTING ALPHA-2 BLOCKER AND DOES THIS WELL.

WHAT ABOUT THE DOPAMINE DEFICIENCY? A BENZODIAZEPINE WAS NEEDED TO BE ADDED TO THE ABOVE REGIMEN TO MAKE THE TREATMENT PALABLE TO THE PATIENT. THIS BENZODIAZEPINE VIA INHIBITING GABA IN INTERNEURONS OF THE VTA SUPPLIED THE DOPAMINE.

CCBHO INITIATIVE

THE EXPRESSED PURPOSE OF THIS INITIATIVE WAS TO DECREASE THE USE OF BENZODIAZEPINES AND OPIOIDS IN METHADONE CENTERS….AND IT WORKED!

CCBHO GIVES THE METHADONE CLINICS A LISTING OF PATIENTS WHO ARE GETTING BENZODIAZEPINE AND/OR OPIOID SCRIPTS. THESE PRESCRIPTIONS WOULD NOT BE REGISTERED AT THE CLINIC NOR WOULD EVIDENCE OF THE DRUGS SHOW IN THE ROUTINE URINES.

Page 57: Decreasing the Use of Prescription Opiates and Benzodiazepines Among Individuals Enrolled in Methadone Programs Kim Castelnovo, RPh Pharmacy Manager, Community.

CCBHO INITIATIVE

THIS SCENARIO WAS VIRTUALLY UNCHANGED. DOCTOR TO DOCTOR COMMUNICATION SPOILED THE ENTERPRISE.
