<p><strong>Background: </strong>Gastrointestinal (GI) disorders are highly prevalent, costly, and complex. Multidisciplinary GI care (MGC), integrating medicine, nutrition, and behavioral health, is a best practice for managing GI needs, but access is limited by availability of gastroenterologists and MGC clinics. Virtual MGC may bridge the gap, but it is unclear the extent to which patients engage in virtual MGC and the outcomes of virtual services delivered at scale.</p><p><strong>Objective: </strong>This study describes patient characteristics, engagement, and outcomes of a large-scale virtual MGC program and evaluates whether dietitian and behavioral health support mediates the association between medical engagement and symptom improvement.</p><p><strong>Methods: </strong>We conducted a retrospective cohort study of 11,345 adult patients receiving virtual MGC with gastroenterologists, GI-specialized advanced practice providers (APPs), registered dietitians, licensed psychologists, and care coordinators between 4/2021 and 8/2025. Patients completed virtual onboarding with a GI APP and medical, dietary, and behavioral interventions delivered through synchronous telehealth and asynchronous chat. Data were from online intake forms and electronic health records. Patient-reported outcomes included symptom control and symptom improvement (Yes/No). Descriptive analyses, logistic regression, and path analysis were conducted across 20 imputed datasets.</p><p><strong>Results: </strong>Virtual MGC patients were 43.3 years on average (SD 12.78), and 66.4% were female (7,532/11,345). Patients primarily presented with Disorders of Gut-Brain Interaction ( 4,460/11,345, 39.3%) and Gastroesophageal Reflux Disease (2,775/11,345, 24.5%). The median wait time for an initial appointment was 6 days (IQR 3-9). Patients had a median of 2 GI visits (IQR 1-3), 2 dietitian visits (IQR 1-3), and 1 behavioral health visit (IQR 0-2). As the number of visits increases, the odds of achieving positive outcomes increases significantly after controlling for age, gender, symptom severity at baseline, symptom frequency at baseline, and days in care.

背景:胃肠道疾病是一种非常普遍、昂贵且复杂的疾病。综合了医学、营养和行为健康的多学科胃肠道护理(MGC)是管理胃肠道需求的最佳实践,但由于胃肠病学家和MGC诊所的可用性,这种治疗方法受到限制。虚拟MGC可能会弥补这一差距,但目前尚不清楚患者参与虚拟MGC的程度以及大规模提供虚拟服务的结果。目的:本研究描述了一个大型虚拟MGC项目的患者特征、参与程度和结果,并评估营养师和行为健康支持是否在医疗参与和症状改善之间起中介作用。方法:在2021年4月至2025年8月期间,我们对11,345名接受虚拟MGC治疗的成年患者进行了回顾性队列研究,其中包括胃肠病学家、gi专业高级实践提供者(APPs)、注册营养师、执业心理学家和护理协调员。患者通过GI APP完成虚拟入组,并通过同步远程医疗和异步聊天提供医疗、饮食和行为干预。数据来自在线摄入表格和电子健康记录。患者报告的结果包括症状控制和症状改善(是/否)。对20个输入数据集进行了描述性分析、逻辑回归和路径分析。结果:虚拟MGC患者平均43.3岁(SD 12.78), 66.4%为女性(7532 / 11345)。患者主要表现为肠脑相互作用障碍(4,460/11,345,39.3%)和胃食管反流病(2,775/11,345,24.5%)。初次预约的中位等待时间为6天(IQR 3-9)。患者平均有2次GI检查(IQR 1-3), 2次营养师检查(IQR 1-3)和1次行为健康检查(IQR 0-2)。随着就诊次数的增加,在控制了年龄、性别、基线症状严重程度、基线症状频率和护理天数后,获得积极结果的几率显著增加。在接受4次以上诊疗的患者中,症状得到改善的占92.39%,症状得到控制的占94.67%,症状不明显或症状轻微的占98.13%。通径分析证实,GI APP参与与增加的营养师和行为健康利用显著相关,这与症状改善有关。从GI APP参与到症状改善的直接途径也很重要。结论:这项创新的研究表明,虚拟优先的MGC模型不仅在全国范围内是可行的,而且在临床多样化的胃肠道人群中有效地实现症状控制和改善。我们提供了在传统临床环境之外成功提供高质量护理的证据。这项工作的独特之处在于分析综合护理的机制,特别是医疗参与如何促进专业营养和行为干预的使用,而这些干预在社区护理中往往是无法获得的。在现实世界中,这种模式为专家短缺提供了一种可扩展的解决方案,确保无论患者的位置或当地专家的供应如何,他们都能获得最佳实践护理。临床试验:

Background: Growth of generative artificial intelligence (GenAI) has exploded in recent years. Many have noted its substantial potential to increase access to scalable digital mental health interventions or provide companions for individuals who are socially isolated. At the same time, seeking mental health support from mainstream GenAI models may involve risks. Several recent examples of exacerbation of delusions have received attention in the popular press, leading to a call for empirical research to document the scope of interactions with GenAI among individuals experiencing symptoms of psychosis.

Objective: This study aimed to evaluate associations of psychosis risk to GenAI use frequency, motivations for use, and GenAI interactions involving potential delusions.

Methods: We conducted a large-scale cross-sectional survey of 1003 young adults in United States, divided the sample of individuals that had used GenAI into "elevated risk" (Prodromal Questionnaire, Brief Version Distress Score ≥20; N=267, 28%) and "low risk" groups (Prodromal Questionnaire, Brief Version Distress Score <20; N=685, 72%), and compared groups on several assessments related to GenAI use.

Results: We found that while members of the elevated risk group were no more likely to have ever used GenAI, they were significantly more likely to report intensive use (odds ratio 1.70 to 2.56; ie, several times per day, more than 30 minutes per day, 6 or more chatbot conversations per day). Those at elevated risk were more likely to report using GenAI to receive social and emotional support and significantly more likely to ascribe human-like roles to their chatbot interactions (odds ratio 1.76 to 3.08; ie, companion, friend, therapist, and romantic partner). Delusion-related interactions were also commonly reported among those at risk for psychosis (item endorsements from 13.3% to 30.7%).

Conclusions: While it is unclear whether they have a positive or negative impact overall, GenAI chatbots may have the potential to impact symptom-related experiences among young adults at risk.

背景:近年来,生成式人工智能(GenAI)迅猛发展。许多人注意到它的巨大潜力,可以增加获得可扩展的数字心理健康干预措施的机会,或为社会孤立的个人提供陪伴。同时,从主流GenAI模式寻求心理健康支持可能存在风险。最近几个妄想加剧的例子引起了大众媒体的注意,导致人们呼吁进行实证研究,以记录精神病症状个体与GenAI相互作用的范围。目的:本研究旨在评估精神病风险与GenAI使用频率、使用动机和涉及潜在妄想的GenAI相互作用的关系。方法:我们对1003名美国年轻人进行了大规模的横断面调查,将使用GenAI的个体样本分为“高风险”组(前驱症状问卷,简短版困扰评分≥20;N=267, 28%)和“低风险”组(前症问卷,简短版本痛苦评分结果:我们发现,虽然高风险组的成员不太可能使用过GenAI,但他们更有可能报告密集使用GenAI(比值比为1.70至2.56;即每天多次,每天超过30分钟,每天6次或更多聊天机器人对话)。那些风险较高的人更有可能使用GenAI来获得社会和情感支持,并且更有可能将类似人类的角色归因于他们的聊天机器人互动(比值比为1.76比3.08,即伴侣、朋友、治疗师和恋人)。妄想相关的相互作用也普遍存在于精神病风险人群中(项目认可从13.3%到30.7%)。结论:虽然目前尚不清楚它们的总体影响是积极的还是消极的,但GenAI聊天机器人可能有可能影响处于风险中的年轻人的症状相关体验。

Unlabelled: Artificial intelligence (AI) promises efficiency and equity in health care. However, adoption remains fragmented due to weak foundations of trust. This Viewpoint highlights the gap between intrinsic trust, based on interpretability, and extrinsic trust, based on functional validation. We propose a contractual framework between AI systems and users defined by 3 promises: reliability, scope and equity, and shift and uncertainty. Illustrated through a vignette, we show how health systems can operationalize these promises through structured evidence and governance, translating trustworthy AI into accountable clinical deployment.

<p><strong>Background: </strong>Opioid use disorder (OUD) remains a critical public health crisis in the United States. Despite widespread policy and clinical interventions, early identification of individuals at risk for developing OUD remains challenging due to limitations in traditional screening approaches and a lack of individualized risk stratification methods. Machine learning (ML) methods offer an opportunity to develop timely, high-performing, and explainable predictive models that can enhance OUD prevention strategies in clinical settings.</p><p><strong>Objective: </strong>This study aims to develop and validate an ML model using electronic health record (EHR) data to predict the 3-month risk of incident OUD among adults initiating opioid therapy and to stratify patients into clinically actionable risk groups.</p><p><strong>Methods: </strong>This prognostic modeling study used 2017-2022 OneFlorida+ EHR data to develop and validate ML algorithms predicting 3-month incident OUD risk. We included 182,083 adults (≥18 y) without cancer, overdose, or OUD or hospice history who received ≥1 outpatient, noninjectable opioid prescription. Using 183 predictors measured in sequential 3-month intervals, we developed an elastic net, least absolute shrinkage and selection operator, gradient boosting machine (GBM), and random forest models on randomly split training, testing, and validation sets. Model performance was assessed using C-statistics, predictive values, and number needed to evaluate, with patients stratified into risk deciles for clinical applicability. Model explainability was assessed using Shapley additive explanations, and fairness was evaluated using standard metrics. We externally validated the best-performing model using an independent cohort from the 2018-2020 UPMC (formerly University of Pittsburgh Medical Center) health system.</p><p><strong>Results: </strong>In the validation sample (n=60,694), GBM (C-statistics=0.879, 95% CI 0.874-0.884) and elastic net (C-statistics=0.872, 95% CI 0.867-0.877) outperformed least absolute shrinkage and selection operator (C-statistics=0.846, 95% CI 0.840-0.851) and random forest (C-statistics=0.798, 95% CI 0.792-0.804), with GBM model requiring the fewest predictors (n=75) for predicting 3-month incident OUD. Using the GBM algorithm to predict the subsequent 3-month OUD risk, the top decile subgroup had a positive predictive value of 3.26%, a negative predictive value of 99.8%, and a number needed to evaluate of 31. The top decile (n=6696) captured ~68% of patients with OUD. Shapley additive explanations analysis identified age, number of outpatient visits, history of back and other pain conditions, comorbidity burden, and opioid prescribing patterns as the strongest predictors of incident OUD. Fairness assessment showed an acceptable false negative rate parity across race, age, and sex. In external validation on the UPMC cohort, the GBM model maintained good discrimination (C-statistics=0.756, 9
背景:阿片类药物使用障碍(OUD)在美国仍然是一个严重的公共卫生危机。尽管有广泛的政策和临床干预措施,但由于传统筛查方法的局限性和缺乏个性化的风险分层方法,早期识别有OUD风险的个体仍然具有挑战性。机器学习(ML)方法为开发及时、高性能和可解释的预测模型提供了机会,可以增强临床环境中的OUD预防策略。目的:本研究旨在开发和验证使用电子健康记录(EHR)数据的ML模型,以预测开始阿片类药物治疗的成年人3个月发生OUD的风险,并将患者分为临床可操作的风险组。方法:该预后建模研究使用2017-2022年OneFlorida+ EHR数据来开发和验证预测3个月事件OUD风险的ML算法。我们纳入了182083名成年人(≥18岁),无癌症、用药过量、无OUD或临终关怀病史,且接受过≥1份门诊非注射阿片类药物处方。使用连续3个月间隔测量的183个预测因子,我们开发了弹性网络、最小绝对收缩和选择算子、梯度增强机(GBM)和随机分割训练、测试和验证集的随机森林模型。使用c统计量、预测值和需要评估的人数来评估模型的性能,并根据临床适用性将患者分为风险十分位数。模型可解释性采用沙普利加性解释进行评估,公平性采用标准指标进行评估。我们使用来自2018-2020年UPMC(原匹兹堡大学医学中心)卫生系统的独立队列从外部验证了表现最佳的模型。结果:在验证样本(n=60,694)中,GBM (C-statistics=0.879, 95% CI 0.874-0.884)和弹性网(C-statistics=0.872, 95% CI 0.867-0.877)优于最小绝对收缩和选择算子(C-statistics=0.846, 95% CI 0.840-0.851)和随机森林(C-statistics=0.798, 95% CI 0.792-0.804),其中GBM模型预测3个月事件OUD所需预测因子最少(n=75)。使用GBM算法预测后续3个月的OUD风险,前十分位亚组阳性预测值为3.26%,阴性预测值为99.8%,需要评估的数字为31。前十分位数(n=6696)占OUD患者的68%。Shapley加性解释分析确定年龄、门诊次数、背部和其他疼痛病史、合并症负担和阿片类药物处方模式是发生OUD的最强预测因子。公平评估显示不同种族、年龄和性别的假阴性率均可接受。在UPMC队列的外部验证中,GBM模型保持了良好的判别(C-statistics=0.756, 95% CI = 0.750-0.762)和有效的风险分层。结论:基于OneFlorida+ EHR数据预测事件OUD的ML算法在UPMC数据的外部验证中表现良好。该算法可能对整个卫生系统的事件OUD风险预测和分层有价值,有可能为早期干预提供信息。

The top decile (n=6696) captured ~68% of patients with OUD. Shapley additive explanations analysis identified age, number of outpatient visits, history of back and other pain conditions, comorbidity burden, and opioid prescribing patterns as the strongest predictors of incident OUD. Fairness assessment showed an acceptable false negative rate parity across race, age, and sex.

背景:美国印第安人和阿拉斯加原住民(AI/AN)社区经历了不成比例的高自杀率。虽然利用电子健康记录(EHR)的机器学习(ML)模型已成为识别自杀风险的有前途的工具,但这些模型与现有筛查实践的最佳整合仍不清楚。目的:本研究的目的是比较平行和串行测试策略,结合ML自杀风险模型和问自杀筛查问题(ASQ)与单独使用ASQ。为此,我们对电子病历数据进行了回顾性的二次分析。该队列包括2019年10月1日至2021年10月2日期间在印度卫生服务(IHS)设施急诊部就诊的成人。方法:敏感性、特异性、预测值和95%置信区间在10个交叉验证的患者水平折叠中平均。最终样本包括7897名美国印第安人患者,就诊26896次,其中824人(3.1%)有ASQ阳性结果,102人(0.4%)在就诊后90天内有自杀企图或死亡的结果。先前使用ihs特定数据开发的逻辑回归ML模型分别在第95和75百分位数处进行操作,以评估高风险和中等风险阈值。进行敏感性分析以评估这段时间内所有急诊科就诊的识别方法。结果:与单独使用ML高危阈值(敏感性0.429,95% CI 0.287-0.572;特异性0.751,95% CI 0.725-0.777; PPV 0.012, 95% CI 0.009-0.014; NPV 0.999, 95% CI 0.998- 0.961; PPV 0.035, 95% CI 0.022-0.048; NPV 0.998, 95% CI 0.997-0.999)或单独使用ASQ(敏感性0.178,95% CI 0.073-0.282;特异性0.751,95% CI 0.725-0.777;特异性0.970,95% CI 0.968 ~ 0.971;PPV 0.022, 95% ci 0.010 ~ 0.034;净现值0.997,95% ci 0.996-0.998)。将ML高危阈值与ASQ串联在一起,以降低敏感性(0.129,95% CI 0.036-0.221)为代价,获得了最大的阳性预测能力(PPV 0.050, 95% CI 0.014-0.086)。最后,采用ML中危阈值的平行检测方法获得了最高的灵敏度(灵敏度0.795,95% CI 0.671-0.920;特异性0.742,95% CI 0.716-0.766; PPV 0.012, 95% CI 0.009-0.014; NPV 0.999, 95% CI 0.989-0.999),没有遗漏任何通过筛查发现的病例。结论:与现有的单独评估ML和筛选工具的研究不同,本研究通过在现实环境中评估并行和串行组合测试策略进行了创新。我们证明,虽然串行测试最大化预测准确性,但它通常是不可行的。相反,平行测试带来了临床“安全网”的价值,可以捕捉标准实践错过的高危患者。最终,将机器学习整合到自杀预防中需要平衡统计准确性与特定设置的现实世界工作流程。临床试验:

<p><strong>Background: </strong>The COVID-19 pandemic has significantly accelerated the development of internet-based hospitals and telepharmacy services. However, their characteristics and evolving trends remain unclear.</p><p><strong>Objective: </strong>This study aimed to assess the associations between distinct pandemic phases and the number of prescriptions, patients' demographic characteristics, drug and disease distribution patterns, and pharmacy service indicators in our internet-based psychiatric hospital.</p><p><strong>Methods: </strong>In this retrospective cross-sectional observational study, we conducted a full-sample census of prescriptions issued in the internet-based psychiatric hospital of the Affiliated Brain Hospital of Guangzhou Medical University during November 2020-December 2023. Cancelled, pending, and test prescriptions were excluded, and no sampling procedure was used. The research timespan was divided into pandemic and postpandemic phases, and trends of prescriptions were evaluated using interrupted time series analysis. Outcome measures, including patients' sex and age, diagnosed disease, drug type, pharmacist audit time, and audit outcome, were analyzed using the bootstrap method, Pearson chi-square analysis, and multinomial logistic regression.</p><p><strong>Results: </strong>The segmented regression model revealed significant positive correlation between months and number of prescriptions during pandemic phase (F<sub>1,16</sub>=6.96; P=.02), whereas no significant correlation was detected in postpandemic phase (F<sub>1,10</sub>=2.77; P=.13). Descriptive analysis with bootstrap method revealed that female population were the majority in the pandemic phase (7297/11,812, 61.78%; 95% CI 60.91%-62.70%) and the postpandemic phase (3520/5518, 63.79%; 95% CI 62.58%-65.18%). Young adults aged 18-40 years were the predominant population in the pandemic phase (5606/11,812, 47.46%; 95% CI 46.63%-48.39%) and postpandemic phase (2657/5518, 48.15%; 95% CI 46.79%-49.37%). Depressive disorder and quetiapine were the most frequently diagnosed disease and prescribed drug in both pandemic phases, respectively. The majority of prescriptions were audited within 5 minutes during the pandemic phase (5999/11,812, 50.79%; 95% CI 49.89%-51.65%), while most prescriptions were audited within 1-12 hours in the postpandemic phase (2031/5518, 36.81%; 95% CI 35.61%-37.95%).

Cancelled, pending, and test prescriptions were excluded, and no sampling procedure was used. The research timespan was divided into pandemic and postpandemic phases, and trends of prescriptions were evaluated using interrupted time series analysis. Outcome measures, including patients' sex and age, diagnosed disease, drug type, pharmacist audit time, and audit outcome, were analyzed using the bootstrap method, Pearson chi-square analysis, and multinomial logistic regression.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;The segmented regression model revealed significant positive correlation between months and number of prescriptions during pandemic phase (F&lt;sub&gt;1,16&lt;/sub&gt;=6.96; P=.02), whereas no significant correlation was detected in postpandemic phase (F&lt;sub&gt;1,10&lt;/sub&gt;=2.77; P=.13).

Depressive disorder and quetiapine were the most frequently diagnosed disease and prescribed drug in both pandemic phases, respectively. The majority of prescriptions were audited within 5 minutes during the pandemic phase (5999/11,812, 50.79%; 95% CI 49.89%-51.65%), while most prescriptions were audited within 1-12 hours in the postpandemic phase (2031/5518, 36.81%; 95% CI 35.61%-37.95%).

Artificial intelligence triage in general practice is developing rapidly within the primary care digital transformation, promising efficiency gains and safety standardization in overwhelmed primary care systems. However, current evidence is drawn from retrospective validations, emergency settings, or vignettes, with scant evaluation of real-world outcomes and almost no equity-stratified safety data, despite known disparities across age, ethnicity, language, and deprivation. From a sociotechnical standpoint, which considers the fit between people, tasks, technology, and organizational context, risks arise not only from algorithmic bias and undertriage but also from human factors, workflow misalignment, governance gaps, and inadequate postdeployment monitoring. We argue that ensuring artificial intelligence triage is safe and equitable requires real-world evaluations in primary care settings, equity-focused performance reporting using theoretically informed frameworks, and rigorous postmarket surveillance. Without these, deployment may widen existing health inequalities rather than moderate them.

在初级保健数字化转型中,全科实践中的人工智能分诊正在迅速发展,有望在不堪重负的初级保健系统中提高效率和安全标准化。然而,目前的证据来自回顾性验证、紧急情况或小插曲,缺乏对现实世界结果的评估,几乎没有公平分层的安全性数据,尽管已知年龄、种族、语言和贫困之间存在差异。从社会技术的角度来看,要考虑人员、任务、技术和组织环境之间的契合度,风险不仅来自算法偏差和分类不足,还来自人为因素、工作流程不一致、治理差距和部署后监控不足。我们认为,确保人工智能分类是安全和公平的,需要在初级保健环境中进行真实世界的评估,使用理论上知情的框架进行以股权为中心的绩效报告,以及严格的上市后监督。如果没有这些,部署可能会扩大而不是缓和现有的卫生不平等。
