Use of IMMPACT domains in clinical trials of acupuncture for chronic pain: a protocol for a methodological survey.

ABSTRACT:

Introduction

Pain is one of the most common and most debilitating complaints among patients. It affects the individual, their relationship with friends and family, their ability to function at work, and their sociability. Acupuncture is one of the therapeutic resources for managing chronic pain. Given the variability of outcome measures in controlled randomised clinical trials on non-oncologicchronic pain (CRCT-NOCP), the Initiative in Methods, Measurements and Pain Assessment in Clinical Trials (IMMPACT) recommends six domains to be covered in evaluating the effectiveness of treatments for chronic pain.

Objective

To check whether the methodological quality of outcome reporting in published trials has used IMMPACT recommendations in measuring CRCT-NOCP outcomes when acupuncture was used as a treatment.

Method

This is a methodological study. We will systematically search for eligible studies in specific databases with a defined strategy. We will use the MeSHterms of 'acupuncture', 'chronic pain' and similar terms, without restrictions on idiom. Eligible studies will include those which are randomised and chose NOCP patients to be treated with acupuncture or control (sham acupuncture or no acupuncture), recruited after September 2004, with ?100 patients. The measured outcomes are to be the presence of outcome domains recommended by IMMPACT, domains reported by the patient or clinician, tools used to measure such domains, as well as other features of the studies. We shall conduct a regression analysis to explore factors which can be associated with the presence of outcome domains according to IMMPACT recommendations.

Ethics and dissemination

This survey will be submitted for presentation at congresses and for publication in a scientific journal. The findings obtained in this study will allow us to measure the quality of the evidence and provide greater transparency in decisions regarding the use of acupuncture as a viable alternative to managing chronic pain.

Project description:Acupuncture is one of the therapeutic resources used for the management of chronic pain. Variability in outcome measurements in randomized clinical trials of non-oncologic chronic pain (RCT-NOCP) generates inconsistencies in determining effects of treatments. The objective of this survey was to assess the adherence to the recommendations made by the Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials (IMMPACT) in the measurement of RCT-NOCP of acupuncture. This methodological research made a systematic search for eligible studies from different sources of information. Eligible studies included those with number of patients ≥100, who randomized and allocated patients with chronic non-oncologic pain to be treated with acupuncture or with "sham" acupuncture, or non-acupuncture. This research included the recommendations for IMMPACT in the measurement of RCT-NOCP: presence of outcomes pain, physical function, emotional state and improvement perception of patient, the source of the outcome information pain and the tools used to measure such domains. From a total of 1,386 studies, 24 were included in this survey. Eleven studies presented low risk of bias. Pain outcome was measured in 23 studies, physical function in 22 studies, emotional state in 14 studies and improvement perception of patient in one study. As for the pain outcome, the patient was the information source in 50% of the studies. The measurement tools recommended for IMMPACT were included in eight studies (35%) that evaluated pain, one study that evaluated the emotional state (7%), and one study that evaluated the improvement perception and satisfaction of patient. It was observed that studies which did not adhere to the recommendations had more favorable results for acupuncture in the outcome pain. This study concludes that randomized clinical trials that used acupuncture to manage chronic pain failed to adhere to IMMPACT recommendations. Clinical societies and IMMPACT do not share the same recommendations. This fact reflects in the diversity of outcomes and instruments adopted in the studies, making it difficult to compare the results.

Project description:BackgroundThe purpose of clinical trials of acupuncture is to help clinicians and patients make decisions about treatment. Yet this is not straightforward: some trials report acupuncture to be superior to sham (placebo) acupuncture while others show evidence that acupuncture is superior to usual care but not sham, and still others conclude that acupuncture is no better than usual care. Meta-analyses of these trials tend to come to somewhat indeterminate conclusions. This appears to be because, until recently, acupuncture research was dominated by small trials of questionable quality. The Acupuncture Trialists' Collaboration, a group of trialists, statisticians and other researchers, was established to synthesize patient-level data from several recently published large, high-quality trials.MethodsThere are three distinct phases to the Acupuncture Trialists Collaboration: a systematic review to identify eligible studies; collation and harmonization of raw data; statistical analysis. To be eligible, trials must have unambiguous allocation concealment. Eligible pain conditions are osteoarthritis; chronic headache (tension or migraine headache); shoulder pain; and non-specific back or neck pain. Once received, patient-level data will undergo quality checks and the results of prior publications will be replicated. The primary analysis will be to determine the effect size of acupuncture. Each trial will be evaluated by analysis of covariance with the principal endpoint as the dependent variable and, as covariates, the baseline score for the principal endpoint and the variables used to stratify randomization. The effect size for acupuncture from each trial--that is, the coefficient and standard error from the analysis of covariance--will then be entered into a meta-analysis. We will compute effect sizes separately for comparisons of acupuncture with sham acupuncture, and acupuncture with no acupuncture control for each pain condition. Other analyses will investigate the impact of different sham techniques, styles of acupuncture or frequency and duration of treatment sessions.DiscussionIndividual patient data meta-analysis of high-quality trials will provide the most reliable basis for treatment decisions about acupuncture. Above all, however, we hope that our approach can serve as a model for future studies in acupuncture and other complementary therapies.
