处方阿片类药物与加巴喷丁类药物同时使用可能会造成严重的药物相互作用风险。然而,对于老年医疗保险阿片类药物使用者慢性非癌性疼痛中同时使用阿片类-加巴喷丁类药物的趋势和患者特征知之甚少。一项横断面研究在2011年至2018年间随机选择慢性非癌性疼痛诊断(指标日期)后3个月内服用≥1个阿片类药物处方的慢性非癌性疼痛老年医疗保险受益人(年龄≥65岁)中进行。在指标日期前6个月的基线中测量患者特征,在指标日期后3个月的随访中测量同时使用≥1天的阿片类加巴喷丁类药物。采用多变量修正泊松回归评估阿片类-加巴喷丁类同时使用的趋势和特征。分析于2021年1月至6月进行。在464,721名慢性非癌性疼痛和处方阿片类药物的符合条件的老年受益人中,阿片类加巴喷丁类药物同时使用的患病率从2011年的17.0%增加到2018年的23.5%(调整患病率=1.48,95% CI=1.45, 1.53)。同时使用阿片类药物的人与仅使用阿片类药物的人相比,往往是非黑人、低收入补贴接受者和南方居民。与同时使用阿片类加巴喷丁类药物相关的临床因素包括诊断为神经性疼痛、多种用药和阿片类药物相关不良事件的危险因素。2011年至2018年期间,患有慢性非癌症疼痛和处方阿片类药物的老年医疗保险受益人同时使用阿片类-加巴喷丁类药物的人数显著增加。未来的研究需要调查并发用药对老年患者预后的影响。减少不适当同时使用的干预措施可能针对具有确定特征的老年患者。
Concurrent use of prescription opioids with gabapentinoids may pose risks of serious drug interactions. Yet, little is known about the trends in and patient characteristics associated with concurrent opioid–gabapentinoid use among older Medicare opioid users with chronic noncancer pain. A cross-sectional study was conducted among Medicare older beneficiaries (aged ≥65 years) with chronic noncancer pain who filled ≥1 opioid prescription within 3 months after a randomly selected chronic noncancer pain diagnosis (index date) in a calendar year between 2011 and 2018. Patient characteristics were measured in the 6-month baseline before the index date, and concurrent opioid–gabapentinoid use for ≥1 day was measured in the 3-month follow-up after the index date. Multivariable modified Poisson regression hwas used to assess the trends and characteristics of concurrent opioid–gabapentinoid use. Analyses were conducted from January to June 2021. Among 464,721 eligible older beneficiaries with chronic noncancer pain and prescription opioids, the prevalence of concurrent opioid–gabapentinoid use increased from 17.0% in 2011 to 23.5% in 2018 (adjusted prevalence ratio=1.48, 95% CI=1.45, 1.53). Concurrent users versus opioid-only users tended to be non-Black, low-income subsidy recipients, and Southern residents. The clinical factors associated with concurrent opioid–gabapentinoid use included having a diagnosis of neuropathic pain, polypharmacy, and risk factors for opioid-related adverse events. Concurrent opioid–gabapentinoid use among older Medicare beneficiaries with chronic noncancer pain and prescription opioids has increased significantly between 2011 and 2018. Future studies are warranted to investigate the impact of concurrent use on outcomes in older patients. Interventions that reduce inappropriate concurrent use may target older patients with identified characteristics.
