摘要

Introduction

We postulateded that providing medication instruction to patients with various orthopedic diseases and scheduled to receive mirogabalin would improve their satisfaction with treatment. The MiroSearch study investigated the impact of medication instruction on treatment satisfaction with mirogabalin.

Methods

This was a multicenter, open-label, exploratory, interventional study, conducted in Japan. The study included outpatients with mild to more severe neuropathic pain (NeP) (numerical rating scale [NRS] score 0–10) due to various orthopedic diseases. Patients received medication instruction for mirogabalin from a physician or pharmacist at baseline and week 4. The primary endpoint was patient treatment satisfaction with mirogabalin.

Results

Of the 201 patients who provided informed consent, 194 were included, and 166 completed the study. Patient treatment satisfaction (at least satisfied) at week 8 was 52.8% (86/163) (95% confidence interval [CI] 44.8–60.6%). Patient understanding at week 8 was associated with patient treatment satisfaction at week 8 (Cochran-Armitage test, p = 0.021 for trend). In cases in which physicians were satisfied or more with treatment at week 8, agreement rate between patient and physician treatment satisfaction at week 8 was 49.1% (80/163), and the disagreement rate was 30.1% (49/163). Patient satisfaction with communication with the physician was associated with patient treatment satisfaction. The NRS score for pain decreased from baseline to week 8 (change from baseline, − 2.0 [95% CI − 2.4, − 1.5], p < 0.001). Treatment-emergent adverse events occurred in 53.8% (105/195) of patients; most were mild or moderate in severity.

Conclusion

Over half of patients with NeP due to orthopedic diseases were satisfied with mirogabalin treatment. Medication instruction can improve patient understanding of their disease and medications and enhance their treatment satisfaction. Furthermore, communication between patients and physicians/pharmacists may contribute to improving patient treatment satisfaction.
