<p><strong>Importance: </strong>Currently, there are no treatments for nocturnal leg cramps (NLCs) that have been proven to be both safe and effective. Seeking safe and effective approaches for managing NLCs is of crucial importance.</p><p><strong>Objective: </strong>To determine whether vitamin K2 is better than placebo in managing NLCs.</p><p><strong>Design, setting, and participants: </strong>This multicenter, double-blind, placebo-controlled randomized clinical trial was conducted in China between September 2022 and December 2023. This study used a volunteer sample comprising community-dwelling individuals 65 years and older with 2 or more documented episodes of NLCs during 2 weeks of screening. Researchers performed a history and physical screening of candidates recruited from the community through advertisements, and eligible participants were randomized in a 1:1 ratio to receive vitamin K2 or a placebo for 8 weeks.</p><p><strong>Interventions: </strong>Patients orally took capsules containing either vitamin K2 (menaquinone 7), 180 μg, or a similar-looking placebo every day for 8 weeks. The study products were custom manufactured to have identical packaging and for the capsules to have matching appearance and identical excipients that shared similar taste and weight.</p><p><strong>Main outcomes and measures: </strong>The primary outcome was the mean number of NLCs per week between the vitamin K2 and the placebo group. Secondary outcomes included the duration of muscle cramps measured in minutes and the severity of muscle cramps assessed using an analog scale ranging from 1 to 10.</p><p><strong>Results: </strong>Among the 310 participants, 111 participants were excluded. Of the 199 enrolled individuals, 108 (54.3%) were female, and the mean (SD) age was 72.3 (5.5) years. A total of 103 patients (51.8%) were randomly assigned to receive vitamin K2 and 96 (48.2%) were assigned to placebo. The mean (SD) baseline weekly frequency of cramps was comparable in both the vitamin K2 group (2.60 [0.81]) and the placebo group (2.71 [0.80]). During the 8-week intervention, the vitamin K2 group experienced a reduction in the mean (SD) weekly frequency of cramps to 0.96 (1.41). Meanwhile, the placebo group maintained mean (SD) weekly frequency of cramps at 3.63 (2.20). The between-group difference was statistically significant (difference, -2.67; 95% CI, -2.86 to -2.49; P < .001). The vitamin K2 group had a more significant mean (SD) reduction in NLC severity (-2.55 [2.12] points) compared with the placebo group (-1.24 [1.16] points). The vitamin K2 group exhibited a more pronounced mean (SD) decrease in the duration of NLCs (-0.90 [0.88] minutes) than the placebo group (-0.32 [0.78] minutes). No adverse events related to vitamin K2 use were identified.</p><p><strong>Conclusions and relevance: </strong>This randomized clinical trial showed that vitamin K2 supplementation significantly reduced the frequency, intensity, and duration of NLCs in an older popul
重要性:目前,尚无经证实安全有效的夜间腿部抽筋(NLCs)治疗方法。寻求安全有效的方法来控制夜间腿抽筋至关重要:目的:确定维生素 K2 在治疗 NLCs 方面是否优于安慰剂:这项多中心、双盲、安慰剂对照随机临床试验于 2022 年 9 月至 2023 年 12 月在中国进行。该研究使用的志愿者样本包括在两周筛查期间有 2 次或 2 次以上 NLC 发作记录的 65 岁及以上社区居民。研究人员对通过广告从社区招募的候选人进行了病史和体格筛查,符合条件的参与者按1:1的比例随机接受维生素K2或安慰剂治疗,为期8周:患者每天口服含有 180 μg 维生素 K2(甲萘醌 7)的胶囊或外观相似的安慰剂,连续服用 8 周。研究产品是定制生产的,包装完全相同,胶囊的外观和辅料完全相同,口感和重量也相似:主要结果是维生素 K2 组和安慰剂组每周 NLC 的平均次数。次要结果包括肌肉痉挛持续时间(以分钟为单位)和肌肉痉挛严重程度(用 1 到 10 的模拟量表进行评估):在 310 名参与者中,有 111 人被排除在外。在 199 名参加者中,108 人(54.3%)为女性,平均年龄(标准差)为 72.3(5.5)岁。共有 103 名患者(51.8%)被随机分配接受维生素 K2 治疗,96 名患者(48.2%)被分配接受安慰剂治疗。维生素 K2 组(2.60 [0.81])和安慰剂组(2.71 [0.80])每周抽筋频率的平均值(标度)基线相当。在为期 8 周的干预期间,维生素 K2 组的平均(标度)每周抽筋频率降至 0.96 (1.41)。与此同时,安慰剂组的平均(标度)每周抽筋频率保持在 3.63(2.20)次。组间差异具有统计学意义(差异,-2.67;95% CI,-2.86 至 -2.49;P 结论及相关性:这项随机临床试验表明,在老年人群中补充维生素 K2 能显著降低 NLC 的频率、强度和持续时间,且安全性良好:试验注册:ClinicalTrials.gov Identifier:NCT05547750。

<p><strong>Importance: </strong>The Medicare Competitive Bidding Program (CBP), a policy that reduced durable medical equipment prices, was implemented starting in 2011. Legislation introduced in 2024 aims to remove supplemental oxygen from the CBP because of concerns that recent decreases in oxygen prescribing are due to lower prices set by the CBP, which may have decreased supply and, in turn, limited oxygen access for patients with chronic lung diseases. However, low-value prescribing of oxygen is also prevalent in practice, and decreased oxygen prescription rates may not have necessarily caused harm. Little is known about the association of the CBP with patient use, outcomes, or spending.</p><p><strong>Objective: </strong>To examine the association between the 2011 and 2013 implementation of the CBP and supplemental oxygen use, clinical outcomes, and supplemental oxygen spending among patients with chronic obstructive pulmonary disease (COPD).</p><p><strong>Design, setting, and participants: </strong>This cohort study used a difference-in-differences (DID) method to evaluate the association between implementation of the CBP and the outcomes of interest. Patients aged 65 to 100 years with COPD living in CBP areas were compared with those living in areas where the CBP was not yet or never implemented. The study included 100% fee-for-service Medicare data of beneficiaries enrolled between July 1, 2009, and December 31, 2015. The data analysis was performed between June 6, 2023, and August 16, 2024.</p><p><strong>Exposure: </strong>The 2011 and 2013 implementation cycles of the Medicare CBP.</p><p><strong>Main outcomes and measures: </strong>The primary outcomes were new prescriptions of oxygen during a 6-month period among beneficiaries with COPD and discontinuation of oxygen during a 6-month period among beneficiaries with COPD previously prescribed oxygen. Secondary outcomes included switches between oxygen types (gas, liquid, or concentrator), all-cause mortality, all-cause unplanned hospitalizations, COPD hospitalizations, and mean monthly allowed charges (total spending) over a 6-month period. The analysis was performed using the Callaway-Sant'Anna method, a dynamic DID model for policies with staggered implementation.</p><p><strong>Results: </strong>Among 5 753 308 Medicare beneficiaries with COPD (mean [SD] age, 79.2 [8.4] years; 55.1% female), 25.9% received supplemental oxygen for at least one 6-month period during the study. The CBP was not associated with differential changes in new oxygen prescribing (DID estimate, -0.19 percentage points; 95% CI, -2.45 to 2.08 percentage points) or oxygen discontinuations (DID estimate, -0.77 percentage points; 95% CI, -8.15 to 6.60 percentage points). Similarly, differential changes were not observed in the secondary outcomes of oxygen switches (DID estimate, -0.04 percentage points; 95% CI, -0.44 to 0.37 percentage points), all-cause mortality (DID estimate, 0.16 percentage points; 95% CI, -7.52 t
重要性:医疗保险竞争性招标计划 (CBP) 是一项降低耐用医疗设备价格的政策,于 2011 年开始实施。2024 年提出的立法旨在将补充氧气从 CBP 中移除,因为人们担心最近氧气处方的减少是由于 CBP 规定的较低价格造成的,这可能会减少供应,进而限制慢性肺病患者获得氧气的机会。然而,低价值的氧气处方在实践中也很普遍,氧气处方率的下降不一定会造成伤害。人们对 CBP 与患者使用、治疗效果或支出之间的关系知之甚少:研究慢性阻塞性肺病(COPD)患者在 2011 年和 2013 年实施 CBP 与补充氧气的使用、临床结果和补充氧气支出之间的关系:这项队列研究采用差分法(DID)来评估 CBP 的实施与相关结果之间的关系。居住在 CBP 地区的 65-100 岁慢性阻塞性肺病患者与居住在 CBP 尚未实施或从未实施地区的患者进行了比较。研究纳入了 2009 年 7 月 1 日至 2015 年 12 月 31 日期间登记的 100%医疗保险付费服务受益人数据。数据分析在 2023 年 6 月 6 日至 2024 年 8 月 16 日期间进行。研究对象:2011 年和 2013 年医疗保险 CBP 实施周期:主要结果是慢性阻塞性肺病受益人在 6 个月内新开的氧气处方,以及慢性阻塞性肺病受益人在 6 个月内停用氧气的情况。次要结果包括氧气类型(气体、液体或浓缩器)之间的转换、全因死亡率、全因非计划住院率、慢性阻塞性肺病住院率以及 6 个月内平均每月允许费用(总支出)。分析采用卡拉韦-桑塔纳方法,这是一种针对交错实施政策的动态 DID 模型:在 5 753 308 名患有慢性阻塞性肺病的医疗保险受益人中(平均 [SD] 年龄为 79.2 [8.4] 岁;55.1% 为女性),25.9% 的人在研究期间至少有 6 个月接受了补充氧气治疗。CBP 与新开氧气处方(DID 估计值,-0.19 个百分点;95% CI,-2.45 至 2.08 个百分点)或停用氧气(DID 估计值,-0.77 个百分点;95% CI,-8.15 至 6.60 个百分点)的差异变化无关。同样,在氧气转换(DID 估计值,-0.04 个百分点;95% CI,-0.44 至 0.37 个百分点)、全因死亡率(DID 估计值,0.16 个百分点;95% CI,-7.52 至 7.84 个百分点)、全因死亡率(DID 估计值,-0.77 个百分点;95% CI,-8.15 至 6.60 个百分点)等次要结果中也未观察到差异变化。84 个百分点)、全因非计划住院(DID 估计值,-0.20 个百分点;95% CI,-10.94 至 10.53 个百分点)或慢性阻塞性肺病住院(DID 估计值,-0.04 个百分点;95% CI,-2.57 至 2.48 个百分点)。月平均允许费用也出现了不同程度的变化(DID 估计值,-326.22 美元;95% CI,-434.76 美元至-217.68 美元):在本研究中,在慢性阻塞性肺病受益人中,医疗保险 CBP 与不同程度的支出降低有关,但与氧气使用或临床结果的不同变化无关。本研究没有发现证据支持目前从 CBP 中取消补充氧气的政策努力。

Importance: Individuals with Alzheimer disease (AD) and Alzheimer disease-related dementias (ADRD) may be at increased risk for adverse outcomes relating to inappropriate prescribing of certain high-risk medications, including antipsychotics, sedative-hypnotics, and strong anticholinergic agents.

Objective: To evaluate the effect of a patient/caregiver and prescriber-mailed educational intervention on potentially inappropriate prescribing to patients with AD or ADRD.

Design, setting, and participants: This prospective, open-label, pragmatic randomized clinical trial, embedded in 2 large national health plans, was conducted from April 2022 to June 2023. The trial included patients with AD or ADRD and use of any of 3 drug classes targeted for deprescribing (antipsychotics, sedative-hypnotics, or strong anticholinergics).

Interventions: Patients were randomized to 1 of 3 arms: (1) a mailing of educational materials specific to the medication targeted for deprescribing to both the patient and their prescribing clinician; (2) a mailing to the prescribing clinician only; or (3) a usual care arm.

Main outcomes and measures: Analysis was performed using a modified intention-to-treat approach. The primary study outcome was the dispensing of the medication targeted for deprescribing during a 6-month study observation period. Secondary outcomes included changes in medication-specific mean daily dose and health service utilization.

Results: Among 12 787 patients included in the modified intention-to-treat analysis, 8742 (68.4%) were female, and the mean (SD) age was 77.3 (9.4) years. The cumulative incidence of being dispensed a medication targeted for deprescribing was 76.7% (95% CI, 75.4-78.0) in the patient and prescriber mailing group, 77.9% (95% CI, 76.5-79.1) in the prescriber mailing only group, and 77.5% (95% CI, 76.2-78.8) in the usual care group. Hazard ratios were 0.99 (95% CI, 0.94-1.04) for the patient and prescriber group and 1.00 (95% CI, 0.96-1.06) for the prescriber only group compared with the usual care group. There were no differences between the groups for secondary outcomes.

Conclusions and relevance: These findings suggest medication-specific educational mailings targeting patients with AD or ADRD and their clinicians are not effective in reducing the use of high-risk medications.

Trial registration: ClinicalTrials.gov Identifier: NCT05147428.

重要性:阿尔茨海默病(AD)和阿尔茨海默病相关性痴呆(ADRD)患者可能会因某些高风险药物(包括抗精神病药、镇静催眠药和强抗胆碱能药)处方不当而增加不良后果的风险:目的:评估患者/护理者和开药者邮寄的教育干预措施对AD或ADRD患者潜在不适当处方的影响:这项前瞻性、开放标签、务实的随机临床试验于 2022 年 4 月至 2023 年 6 月在 2 个大型国家医疗计划中进行。试验对象包括患有注意力缺失症(AD)或注意力缺失性精神障碍(ADRD)并使用3类目标减量药物(抗精神病药、镇静催眠药或强抗胆碱能药)中任何一类药物的患者:患者被随机分配到 3 个干预组中的 1 个:(1) 向患者及其开处方的临床医生邮寄针对停药目标药物的教育材料;(2) 仅向开处方的临床医生邮寄教育材料;或 (3) 常规护理组:采用改良的意向治疗法进行分析。主要研究结果是在为期 6 个月的研究观察期内,针对取消处方的药物的配发情况。次要结果包括特定药物平均日剂量和医疗服务利用率的变化:在纳入修正意向治疗分析的 12 787 名患者中,有 8 742 人(68.4%)为女性,平均(标清)年龄为 77.3(9.4)岁。在患者和处方医生邮寄组中,被处方为取消处方目标药物的累计发生率为 76.7% (95% CI, 75.4-78.0);在仅处方医生邮寄组中,发生率为 77.9% (95% CI, 76.5-79.1);在常规护理组中,发生率为 77.5% (95% CI, 76.2-78.8)。与常规护理组相比,患者和开处方者组的危险比为 0.99(95% CI,0.94-1.04),仅开处方者组的危险比为 1.00(95% CI,0.96-1.06)。在次要结果方面,各组之间没有差异:这些研究结果表明,针对AD或ADRD患者及其临床医生的特定药物教育邮件并不能有效减少高风险药物的使用:试验注册:ClinicalTrials.gov Identifier:NCT05147428。
