Effect of Low Back Pain Risk-Stratification Strategy on Patient Outcomes and Care Processes: the MATCH Randomized...

Area of Science:

• Health Services Research
• Clinical Practice Guidelines
• Musculoskeletal Disorders

Background:

• The STarT Back strategy, a risk-stratification approach for low back pain (LBP), has shown promise in improving patient function and reducing costs in England.
• Implementing this strategy in a US healthcare setting required adaptation and evaluation.

Purpose of the Study:

• To evaluate the effectiveness of an adapted STarT Back strategy for managing non-specific low back pain in a US primary care setting.
• To assess the impact of the intervention on patient function, pain severity, and healthcare utilization.

Main Methods:

• A pragmatic cluster randomized trial involving six primary care clinics, with three randomized to the STarT Back intervention and three as controls.
• Adult patients with non-specific LBP were followed for 6 months, with data collected at 2 weeks, 2 months, and 6 months post-visit.
• The intervention included training for primary care clinicians and physical therapists on the STarT Back Tool and its integration into electronic health records.

Main Results:

• Clinicians utilized the STarT Back Tool for approximately half of the patients but did not modify their treatment recommendations based on the risk stratification.
• The intervention demonstrated no statistically significant effect on primary outcomes, including back-related physical function and pain severity, at 2 or 6 months.
• Secondary outcomes, such as healthcare utilization, also showed no significant difference between the intervention and control groups.

Conclusions:

• A resource-intensive implementation of the STarT Back strategy in a US primary care setting did not yield improvements in patient outcomes or healthcare use.
• The findings suggest that adaptation and training alone may not be sufficient to translate the benefits of the STarT Back strategy observed in other settings to the US healthcare context.
