This study aimed to explore the effect of polypharmacy and hyperpolypharmacy on surgical outcomes in older patients with LSS based on health\u2010related quality of life (HRQOL) and locomotive syndrome.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Consecutive patients aged \u226565\u2009years who underwent lumbar spinal surgery for LSS were retrospectively reviewed. We assessed the preoperative and 1\u2010 and 2\u2010year postoperative scores of three common HRQOL tools and the 25\u2010question Geriatric Locomotive Function Scale. The patients were classified into the hyperpolypharmacy group (those taking \u226510 medications), polypharmacy group (those taking 6\u20139 medications) and non\u2010polypharmacy group (those taking \u22645 medications).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>In total, 148 participants were evaluated. Among them, 35 were included in the non\u2010polypharmacy group. There were no significant changes in the HRQOL and locomotive syndrome stage at baseline, even with polypharmacy progression. However, the HRQOL and locomotive syndrome stage worsened postoperatively with polypharmacy progression. When surgical efficacy was directly examined, results showed that the surgical outcomes were significantly associated with polypharmacy progression in older patients with LSS, even after adjusting for potential confounders.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Polypharmacy, especially hyperpolypharmacy, had a negative impact on surgical outcomes in older patients with LSS.
