Impact of modified-release opioid use on clinical outcomes following total hip and knee arthroplasty: a propensity score-matched cohort study

Modified-release opioids are often prescribed for the management of moderate to severe acute pain following total hip and knee arthroplasty, despite recommendations against their use due to increasing concerns regarding harm. The primary objective of this multicentre study was to examine the impact of modified-release opioid use on the incidence of opioid-related adverse events compared with immediate-release opioid use, among adult inpatients following total hip or knee arthroplasty. Data for total hip and knee arthroplasty inpatients receiving an opioid analgesic for postoperative analgesia during hospitalisation were collected from electronic medical records of three tertiary metropolitan hospitals in Australia. The primary outcome was the incidence of opioid-related adverse events during hospital admission. Patients who received modified with or without immediate-release opioids were matched to those receiving immediate-release opioids only (1:1) using nearest neighbour propensity score matching with patient and clinical characteristics as covariates. This included total opioid dose received. In the matched cohorts, patients given modified-release opioids (n = 347) experienced a higher incidence of opioid-related adverse events overall, compared with those given immediate-release opioids only (20.5%, 71/347 vs. 12.7%, 44/347; difference in proportions 7.8% [95%CI 2.3–13.3%]). Modified-release opioid use was associated with an increased risk of harm when used for acute pain during hospitalisation after total hip or knee arthroplasty.

农村老年人老化期望现状及影响因素研究

目的 了解农村老年人的老化期望现状，分析其影响因素，为针对干预提供参考。 方法 采用一般资料调查表、UCLA孤独感量表简化版、老化期望量表、简版自我感知老化量表对199名农村老年人进行问卷调查。 结果 老化期望总分为32.72±9.18，孤独感得分为15.11±3.82，自我感知老化得分为52.75±2.76；多元线性回归分析显示，性别、婚姻状况、患慢性病种数、独居、孤独感、自我感知老化及经济来源是农村老年人老化期望的影响因素（调整R2=0.612，均P＜0.05）。 结论 农村老年人的老化期望水平较低，女性、孤独、无配偶、患慢性病较多、老化态度消极及低收入人群是关注的重点。

超微经皮肾镜取石术在直径1.5～2.5 cm肾及输尿管上段结石患者中的应用

目的探讨超微经皮肾镜取石术(UMP)应用于直径1.5~2.5 cm肾及输尿管上段结石患者中的安全性和有效性。方法回顾性分析2018年6月-2020年6月宿迁市第一人民医院收治的60例直径为1.5~2.5 cm肾及输尿管上段结石患者的临床资料,均采用UMP治疗,分析患者手术时间、住院时间、手术成功率、结石清除率、并发症发生率及额外镇痛药使用情况。结果60例患者均一期建立通道并顺利完成手术。所有患者均未行单通道手术,未接受输血,无毗邻脏器损伤(肠道、肝脏和脾脏等),无血气胸发生;存在尿外渗或者有明显症状的腹膜后灌注液患者3例(5.0%),均行保守治疗好转;发热(体温高于38℃)5例(8.3%),均对症治疗后好转;无感染性休克患者。手术时间为35~98 min,平均(56.1±21.3)min;术后住院天数为3~8 d,平均(4.1±1.8)d;术后立即评估结石清除率为85.0%(51/60),术后1个月评估结石清除率为91.7%(55/60);术后镇痛药使用率为15.0%(9/60)。结论UMP是治疗直径1.5~2.5 cm肾及输尿管上段结石安全、有效的治疗方法之一,值得临床推广。
