Treatment-seeking opioid dependent patients present frequently with chronic pain (CP). This pilot study examined the feasibility and utility of a single-item rapid screening tool for identifying CP with implications for SUD treatment in a sample of patients presenting for inpatient opioid detoxification (n=110). Most respondents (91.2%) reported pain in the past week. Forty-seven (42.8%) had CP. Individuals with severe CP had significantly greater depressive symptom severity, pain-related functional interference, and were more likely to be on disability than individuals with mild to moderate CP or no CP. The relationships were supported in a multivariate model. The results suggest it is feasible and important to assess for CP severity in SUD treatment settings.
Keywords chronic pain; opioid dependence; assessmentPatients with opioid use disorders present frequently present with chronic pain (CP). These patients are more likely to have higher rates of psychosocial stressors than their non-pain counterparts, which places them at greater risk for difficulties with their substance use disorder 1, 2 . Because pain is common in SUD populations, clinicians would benefit from an efficient and clinically meaningful method to identify those patients whose pain warrants direct attention in their SUD treatment.In pain clinics, where pain is typically the reason for seeking treatment, assessment of chronic pain includes information regarding pain severity and pain-related functional interference 3 . Pain-related functional interference is associated disproportionately with increased pain severity, with greater interference most likely when pain severity is moderate or greater. When assessing cancer and chronic pain, categorizing the level of pain as mild (1-4), moderate (5-6), or severe (7-10) on a 10-point numeric rating scale provides a simple, reliable, and valid method for communicating with patients about pain and guiding pain-related treatment decisions 4-6 .In contrast, there has been relatively little research regarding the assessment of chronic pain and its severity among patients with co-occurring SUD. In SUD treatment, pain is not generally the primary focus of treatment. Thus, in addition to categorizing pain, clinicians must determine the extent to which pain may be relevant to the SUD. One approach is to determine the extent to which pain is associated with other factors that may affect the likelihood of continued substance use or relapse (e.g. psychosocial stressors) 7 . The purpose of this pilot study was to examine the feasibility and utility of a single-item rapid screening
METHODSParticipants were 110 opioid-dependent adults, age 18 or older, admitted for detoxification to one of three inpatient units in Massachusetts. Participants were excluded if they were unable to provide informed consent due to cognitive impairment, psychiatric instability, or language barrier. After receiving approval from the McLean Hospital Institutional Review Board, the authors obtained written informed consent and admin...
