The effectiveness of self-management interventions in adults with chronic orofacial pain: A systematic review, meta-analysis and meta-regression.

BACKGROUND

Psychosocial risk factors associated with chronic orofacial pain are amenable to self-management. However, current management involves invasive therapies which lack an evidence base and has the potential to cause iatrogenic harm.

OBJECTIVES

To determine: (a) whether self-management is more effective than usual care in improving pain intensity and psychosocial well-being and (b) optimal components of self-management interventions.

DATABASES AND DATA TREATMENT

Cochrane Oral Health Group Trials Register, Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, PsycINFO, WHO International Clinical Trials Registry Platform and Clinical Trials.gov were searched. Meta-analysis was used to determine effectiveness, and GRADE was used to rate quality, certainty and applicability of evidence.

RESULTS

Fourteen trials were included. Meta-analyses showed self-management was effective for long-term pain intensity (standardized mean difference [SMD] -0.32, 95% confidence interval [CI] -0.47 to -0.17) and depression (SMD -0.32, 95% CI -0.50 to -0.15). GRADE analysis showed a high score for certainty of evidence for these outcomes and significant effects for additional outcomes of activity interference (-0.29 95% CI -0.47 to -0.11) and muscle palpation pain (SMD -0.58 95% CI -0.92 to -0.24). Meta-regression showed nonsignificant effects for biofeedback on long-term pain (-0.16, 95% CI -0.48 to 0.17, p-value = 0.360) and depression (-0.13, 95% CI -0.50 to 0.23, p-value = 0.475).

CONCLUSIONS

Self-management interventions are effective for patients with chronic orofacial pain. Packages of physical and psychosocial self-regulation and education appear beneficial. Early self-management of chronic orofacial pain should be a priority for future testing.

SIGNIFICANCE

This systematic review provides clear evidence for effectiveness of combined biomedical and psychological interventions (incorporating self-management approaches) on long-term outcomes in the management of chronic orofacial (principally TMD) pain. Self-management should be a priority for early intervention in primary care in preference to invasive, irreversible and costly therapies. Further research is needed firstly to clarify the relative effectiveness of specific components of self-management, both individually and in conjunction, and secondly on outcomes in other types of chronic orofacial pains.
