About this study

Official title: Tapering of Prescribed Opioids in Patients With Long-term Non-malignant Pain - Efficacy and Effects on Pain, Pain Cognitions, and Quality of Life (TOPIO): a Study Protocol for a Randomized Controlled Clinical Trial With a 12 Month Follow-up

This randomized controlled study compares tapering of long-term opioid therapy in a population with chronic non-cancer pain with control group constituted of waiting list. Half of participants receives intervention at baseline and the other half are controls but receives intervention after 4 months. Ethical approval to follow up excluded participants denying tapering at baseline.

Read the detailed description

Chronic non-cancer pain is a major problem in society and a common cause to seek health care. The suffering is complex as it, besides pain, often includes psychological symptoms and may decrease the ability to participate in work life. Pharmacological treatments have limited possibilities to ease suffering. Opioids used in this population have evidence to ease pain and to some extent increase physical ability when used in limited treatment periods and in selected patients. Medium to long-term opioid therapy, extended beyond three months, lack evidence of easing pain or increase physical ability.

The current study is conducted on three specialized pain care units (Skane University Hospital; Lund, Sahlgrenska University Hospital Gothenburg and University Hospital, Linkoeping) and aims at taper long-term opioid therapy with support from physician and nurse and study the effects of tapering.

Method: Randomized controlled study, without concealment. Waiting-list constitutes the control-group. Intervention means tapering with a motivated patient. Follow up at four and twelve months.

Primary end-point: collected opioid prescriptions registered in The National Board of Health and Welfare registry expressed in milligram of morphine equivalent.

Secondary end-point: Data will be retrieved from the Swedish Quality Registry for Pain Rehabilitation. The database contains participants' self-report of variables measuring the impact of rehabilitation on depressive symptoms, anxiety, rating of pain and acceptance to pain. Assessments are made prior to, at the end of and one year after discharge of the rehabilitation program.

As denying tapering or participation is shown to be as common as decision to taper drugs at baseline an extended ethical approval was acquired also retrospective. This approval covers obtaining collected prescribed medication and prescribed opioid replacement therapy (Buprenorphine or Methadone) after one year. The study may describe the excluded population better this way.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Opioid consumption

    Data retrieved from National Boars of Health and Welfare, collected prescribed opioid drugs

    Measured: 12 months

  2. Opioid consumption

    Self reported consumption

    Measured: 4 months

Secondary outcomes (1)
  1. Numeric Pain Rating Scale (NPRS)

    NPRS was used to capture the patient's level of pain intensity. Patients rate their average level of pain the last week. The 11-point scale spans from the left with the phrase "no pain" i.e. 0 and on the right to the phrase "worst imaginable pain" i.e. 10.

    Measured: 12 months
