To test the efficacy of a tailored intervention regarding patient barriers to pain management and pain duration, pain severity, and pain-related interference with daily life
Patients who called the Cancer Information Service and reported moderate to severe pain were asked to stay on the line and queried about consent for study participation. Consenting participants were randomized to one of three groups: the control group, which responded to a single-item screening measure regarding pain and received no intervention; the assessment-only group, which responded to all baseline assessment measurement tools and provided follow-up outcome measures but received no intervention; or the experimental group, which received the intervention. The intervention consisted of determination of barriers, as measured by a standardized assessment, and delivery of a standardized scripted message relating to each barrier identified. Pain duration, pain severity, pain-related interference with life, and barriers were assessed at baseline, during the initial telephone call, and via a follow-up call approximately 28 days after the intervention. Analysis compared the cost of the intervention to the cost of the assessment-only group. Supervisory staff monitored 10% of calls for general quality control regarding eligibility and invitation to participate. Staff who made the follow-up phone calls, to measure outcomes, were blinded to study-group assignment.
Randomized three-group study
The targeted telephonic intervention had a positive impact on attitudinal barriers to pain management but had no impact on other pain-related outcomes. In regard to effect on barriers, results were similar in the assessment-only and intervention groups.
Providing telephonic assessment of patient barriers to pain management and information about pain management are effective means of reducing those barriers. The effectiveness of the specified interventions and the effect of barrier reduction on overall pain control and management remains unclear.
