Abstract

Objective: Testing stepped-care approaches that address both depression and low back pain are needed to optimize outcomes in older adults. Methods: This university-based late-life depression research center assessed 227 adults aged ≥ 60 years with chronic low back pain and depression. In Phase 1 participants received 6 weeks of low-dose venlafaxine (≤150 mg/day). Nonresponders were randomized to 10 weeks of high-dose venlafaxine (up to 300 mg/day) plus problem-solving therapy (PST) or high-dose venlafaxine with supportive management. Definition of response was 2 weeks of Patient Health Questionnaire-9 ≤ 5 and ≥30% pain reduction on a numeric rating scale. Function was measured with the Short Physical Performance Battery (SPPB) and Roland Morris Disability Questionnaire (RMDQ). Results: Of those who completed Phase 1 (N = 209), 78.5% (N = 164) were nonresponders and 139 proceeded to Phase 2, with 68 randomized to venlafaxine/PST and 71 randomized to venlafaxine/supportive management. Of those in venlafaxine/PST, 41.2% (28/68) responded, and of those in venlafaxine/supportive management, 39.4% (28/71) responded. Cumulative proportion responding over time did not differ across the two arms (hazard ratio: 1.07; 95% confidence interval: 0.63–1.80). We observed clinically significant improvements in physical performance (SPPB) and disability (RMDQ) across both Phase 1 and 2, independent of intervention. Over 12 months of follow-up there was no difference between groups for stability of depression, pain, or disability. Conclusion: The combination of antidepressant pharmacotherapy and PST was not superior to antidepressant pharmacotherapy and supportive management. Clinically, the rates of response and stability of response over 1 year observed in both groups suggest that these approaches may have clinical utility in these chronically suffering patients.
