Long Term Outcomes of Lumbar Epidural Steroid Injections for Spinal Stenosis

Not Applicable

Completed

Conditions: Lumbar Spinal Stenosis

Interventions: Other: Individualized report

Registration Number: NCT02260401

Lead Sponsor: University of Washington

Brief Summary: Spinal stenosis is one of the most common causes of low back pain among older adults and can result in significant disability. Despite this, it still isn't known which treatments are most effective or what outcomes are most important to these older adults. Through a Patient Centered Outcomes Research Institute (PCORI) contract, the investigators are building on the existing infrastructure of an AHRQ-funded (ARRA CHOICE award) comparative effectiveness research (CER) trial of epidural steroid injections (ESI) for spinal stenosis (the LESS trial) to address several critical research questions. The proposed study will answer the following key questions. Do decision aids tailored to older adults with spinal stenosis change patient decision-making regarding subsequent treatments? Do patients respond differently at subsequent outcome assessments time-points after receiving tailored decision aids that contain their own individual outcome data from prior treatments? The investigators hypothesize that providing these individualized reports will allow patients to make more informed choices regarding subsequent treatments, leading to reduced use of ineffective treatments and improved outcomes overall.

Detailed Description: LESS trial participants will be randomized to receive the individualized outcome report before the 18-month interview or after the 24-month follow up. Both groups will be asked to rank outcome domains of most importance to them, to answer questions regarding their beliefs about receiving future treatments for spinal stenosis and to complete the standard self-reported outcomes questionnaire. In addition, we will ask the study participants whether the information presented in the individualized report was helpful in deciding their future epidural injection treatments as well as if the content of the reports was easy to understand. At 24 months, we will repeat the interview and the outcomes assessment. We will again compare the groups in terms of their responses to determine if there are lasting differences in how patients who received the individualized reports make decisions regarding future treatments and respond to the self-reported outcomes questions. In addition, we will compare healthcare utilization between the two groups from 18 months to 24 months to determine if providing the individualized outcomes reports changed treatment utilization (i.e., do people who receive the report undergo fewer subsequent injections or other treatments for pain?). We hypothesize that providing these individualized reports will allow patients to make more informed choices regarding subsequent treatments, leading to reduced use of ineffective treatments and improved outcomes overall.

Arm && Interventions

Group	Intervention	Description
Individualized report	Individualized report	Each patient in this group will receive an individualized report with their own outcome data (pain and function) during the first year of the LESS trial. They will receive these reports at 18 months.

Primary Outcome Measures

Name	Time	Method
Utilization of ESI	24 months	We will measure whether or not providing these individualized reports to patients impacts patients decision-making regarding use of epidural steroid injections between 18 and 24 months

Secondary Outcome Measures

Name	Time	Method
Healthcare Utilization	24 months	We will determine if providing individualized reports to the LESS trial participants at 198 months impacts healthcare utilization for spinal stenosis between 18 and 24 months (including doctors visits, physical therapy, surgery, opioid use)
