A female patient in her early 40s presented with a several-month history of gait unsteadiness and dragging her left leg. She had a background of congenital hydrocephalus, treated with a ventriculoatrial shunt. On examination, she had increased tone and brisk reflexes in the lower limbs and a positive Hoffmann sign. A computed tomography (CT) scan and shunt series x-rays identified hydrocephalus secondary to a disconnected shunt. Magnetic resonance imaging (MRI) of her cervical spine was also performed as part of the workup for her presenting symptoms and demonstrated features compatible with degenerative cervical myelopathy (DCM). The patient subsequently underwent a shunt revision. Following the operation, her walking and hand function deteriorated over a period of several weeks. She consequently underwent an anterior cervical decompression and fusion for DCM, which partially improved her symptoms. The sequence of events suggests that the shunt surgery may have precipitated a worsening of the DCM. Possible explanations include spinal cord injury related to neck extension or hypoperfusion during intubation and general anesthesia or the loss of cerebrospinal fluid cushioning following the reinstitution of effective cerebrospinal fluid shunting. Surgeons should be alert to this possibility and offer prompt surgical intervention for DCM if required.

Background: Since most people in low-income countries do not have access to reliable laboratory services, early diagnosis of life-threatening diseases like COVID-19 remains challenging. Facilitating real-time assessment of the health status in a given population, mobile health (mHealth)-supported syndrome surveillance might help identify disease conditions earlier and save lives cost-effectively.
Objective: This study aimed to evaluate the potential use of mHealth-supported active syndrome surveillance for COVID-19 early case finding in Addis Ababa, Ethiopia.
Methods: A comparative cross-sectional study was conducted among adults randomly selected from the Ethio telecom list of mobile phone numbers. Participants underwent a comprehensive phone interview for COVID-19 syndromic assessments, and their symptoms were scored and interpreted based on national guidelines. Participants who exhibited COVID-19 syndromes were advised to have COVID-19 diagnostic testing at nearby health care facilities and seek treatment accordingly. Participants were asked about their test results, and these were cross-checked against the actual facility-based data. Estimates of COVID-19 detection by mHealth-supported syndromic assessments and facility-based tests were compared using Cohen Kappa (κ), the receiver operating characteristic curve, sensitivity, and specificity analysis.
Results: A total of 2741 adults (n=1476, 53.8% men and n=1265, 46.2% women) were interviewed through the mHealth platform during the period from December 2021 to February 2022. Among them, 1371 (50%) had COVID-19 symptoms at least once and underwent facility-based COVID-19 diagnostic testing as self-reported, with 884 (64.5%) confirmed cases recorded in facility-based registries. The syndrome assessment model had an optimal likelihood cut-off point sensitivity of 46% (95% CI 38.4-54.6) and specificity of 98% (95% CI 96.7-98.9). The area under the receiver operating characteristic curve was 0.87 (95% CI 0.83-0.91). The level of agreement between the mHealth-supported syndrome assessment and the COVID-19 test results was moderate (κ=0.54, 95% CI 0.46-0.60).
Conclusions: In this study, the level of agreement between the mHealth-supported syndromic assessment and the actual laboratory-confirmed results for COVID-19 was found to be reasonable, at 89%. The mHealth-supported syndromic assessment of COVID-19 represents a potential alternative method to the standard laboratory-based confirmatory diagnosis, enabling the early detection of COVID-19 cases in hard-to-reach communities, and informing patients about self-care and disease management in a cost-effective manner. These findings can guide future research efforts in developing and integrating digital health into continuous active surveillance of emerging infectious diseases.

<p><strong>Background: </strong>The HIV epidemic remains a major public health concern, particularly among youths living with HIV. While the availability of antiretroviral therapy has significantly improved the health outcomes of people living with HIV, there is growing evidence that youths living with HIV may be at increased risk of cardiovascular disease.

One potential explanation is that HIV-related biomarkers, including detectable viral load (VL) and low cluster of differentiation 4 (CD4) lymphocyte counts, may contribute to increased cardiovascular risk.

We found that those with CD4 lymphocyte counts of ≤200 had significantly higher cardiovascular risk, as assessed by Cardiac Risk Score2, than those with CD4 lymphocyte counts of >200 (P=.002). After adjusting for demographic and clinical factors, we found that for every 1000-point increase in VL copies/mL, the probability of having cardiovascular risk (Cardiac Risk Score2) increased by 38%. When measuring the strength of this connection, we observed a minor effect of VL on increased cardiovascular risk (β=.134, SE 0.014; P=.006). We obtained similar results with Cardiac Risk Score1, but the effect of CD4 lymphocyte counts of ≤200 was no longer significant.

背景:艾滋病毒的流行仍然是一个重大的公共卫生问题,尤其是在感染艾滋病毒的青少年中。虽然抗逆转录病毒疗法的出现大大改善了艾滋病毒感染者的健康状况,但越来越多的证据表明,感染艾滋病毒的青少年罹患心血管疾病的风险可能会增加。然而,人们对艾滋病病毒感染者和心血管疾病之间的内在机制仍然知之甚少。一种可能的解释是,与艾滋病病毒相关的生物标志物,包括可检测到的病毒载量(VL)和低分化4群(CD4)淋巴细胞计数,可能会导致心血管风险增加。尽管这些生物标志物具有潜在的重要性,但对感染 HIV 的青少年中 HIV 相关生物标志物与心血管风险之间的关系研究不足:为了填补这一空白,我们研究了可检测到的 VL 和低 CD4 淋巴细胞计数(两者都是 HIV 未被抑制的表现)是否与感染 HIV 的青少年的心血管风险有关:我们分析了来自美国 7 家青少年 HIV 诊所的电子健康记录数据(813 名青少年 HIV 感染者)。我们使用多变量线性回归法研究了可检测到的 VL 和 CD4 淋巴细胞计数≤200 与心血管风险评分之间的关系:在我们的研究中,近一半的参与者(366/766,47.8%)检测到了 VL,表明艾滋病毒未被抑制,而其中 8.6%(51/593)的 CD4 淋巴细胞计数≤200,表明免疫功能减弱。我们发现,CD4 淋巴细胞计数≤200 者的心血管风险明显高于 CD4 淋巴细胞计数>200 者(P=.002)。在对人口统计学和临床因素进行调整后,我们发现 VL 拷贝数/毫升每增加 1000 个点,心血管风险(心脏风险评分 2)的概率就会增加 38%。在衡量这种联系的强度时,我们观察到 VL 对心血管风险增加的影响较小(β=.134,SE 0.014;P=.006)。我们通过心脏风险评分 1 得出了类似的结果,但 CD4 淋巴细胞计数≤200 的影响不再显著。总之,我们的研究结果表明,在感染艾滋病毒的青少年中,可检测到的VL与心血管风险增加有关,CD4淋巴细胞计数也可能在这种关系中发挥作用:我们的研究强调,在感染艾滋病毒的青少年中,检测到的 VL 所表明的艾滋病毒未得到抑制与心血管风险增加之间存在重要关联。这些发现强调了在这一人群中实施既能抑制 VL 又能降低心血管风险的干预措施的重要性。通过调整干预措施以满足青少年的独特需求,我们可以在整个 HIV 护理过程中和整个生命周期中促进整体健康。最终,这些努力有可能改善感染 HIV 的青少年的健康状况和生活质量:RR2-10.2196/11185。

背景:耗氧量是评价心脏病患者,特别是心力衰竭患者的一个重要指标,可在高级心肺运动试验中测量。然而,技术进步现在允许在许多消费级和医疗级可穿戴设备中估计该参数,使医疗提供者可以在对患者进行初步评估时使用该参数。我们报告一例表面上健康的40岁男性,由于Apple Watch (Apple Inc .)的低心脏健康通知而前来评估。这一警报引发了彻底的检查,诊断为家族性非缺血性心肌病,左心室收缩功能严重降低。虽然使用可穿戴设备测量氧气消耗和相关参数是有希望的,但需要进一步的研究来验证。目的:本报告的目的是研究可穿戴设备作为普通人群和心血管风险增加人群心脏健康筛查和风险分层工具的潜在用途,特别是通过测量峰值耗氧量(VO2)。我们讨论了使用可穿戴设备测量氧气消耗的可能优势,并建议将其整合到常规患者评估和随访过程中。鉴于目前的证据和局限性,我们鼓励研究人员和临床医生探索将可穿戴设备带入临床实践。方法:该病例在Sheba医疗中心确诊,并通过Apple Watch Series 6监测患者的心脏健康状况。病人在就诊后接受了全面的心脏检查。随后,我们检索了有关VO2峰值监测和可用可穿戴设备的临床应用的文献。结果:患者提供的Apple Watch数据显示,VO2峰值(心脏健康的替代指标)降低,在治疗开始后有所改善。心脏病检查证实家族性非缺血性心肌病伴左心室收缩功能严重降低。对文献的回顾揭示了在心脏和非心脏情况下监测峰值VO2的潜在临床益处。此外,市场上的几种设备被确定可以允许准确的耗氧量测量;然而,未来的研究和批准的食品和药物管理局(FDA)仍然是必要的。结论:本病例报告强调了可穿戴设备的峰值VO2测量在普通人群和心血管疾病风险增加人群的早期识别和心脏健康筛查中的潜在效用。将可穿戴设备集成到常规患者评估中可以在诊断工作流程中更早地呈现。心脏健康可以使用可穿戴设备连续测量,允许密切监测功能容量参数。设备需要谨慎使用,进一步的研究是有必要的。

Background: ChatGPT, a dialogue-based artificial intelligence language model, has shown promise in assisting clinical workflows and patient-clinician communication. However, there is a lack of feasibility assessments regarding its use for perioperative patient education in thoracic surgery.
Objective: This study aimed to assess the appropriateness and comprehensiveness of using ChatGPT for perioperative patient education in thoracic surgery in both English and Chinese contexts.
Methods: This pilot study was conducted in February 2023. A total of 37 questions focused on perioperative patient education in thoracic surgery were created based on guidelines and clinical experience. Two sets of inquiries were made to ChatGPT for each question, one in English and the other in Chinese. The responses generated by ChatGPT were evaluated separately by experienced thoracic surgical clinicians for appropriateness and comprehensiveness based on a hypothetical draft response to a patient's question on the electronic information platform. For a response to be qualified, it required at least 80% of reviewers to deem it appropriate and 50% to deem it comprehensive. Statistical analyses were performed using the unpaired chi-square test or Fisher exact test, with a significance level set at P<.05.
Results: The set of 37 commonly asked questions covered topics such as disease information, diagnostic procedures, perioperative complications, treatment measures, disease prevention, and perioperative care considerations. In both the English and Chinese contexts, 34 (92%) out of 37 responses were qualified in terms of both appropriateness and comprehensiveness. The remaining 3 (8%) responses were unqualified in these 2 contexts. The unqualified responses primarily involved the diagnosis of disease symptoms and surgical-related complications symptoms. The reasons for determining the responses as unqualified were similar in both contexts. There was no statistically significant difference (34/37, 92% vs 34/37, 92%; P=.99) in the qualification rate between the 2 language sets.
Conclusions: This pilot study demonstrates the potential feasibility of using ChatGPT for perioperative patient education in thoracic surgery in both English and Chinese contexts. ChatGPT is expected to enhance patient satisfaction, reduce anxiety, and improve compliance during the perioperative period. In the future, there will be remarkable potential application for using artificial intelligence, in conjunction with human review, for patient education and health consultation after patients have provided their informed consent.
背景:ChatGPT是一种基于对话的人工智能语言模型,在辅助临床工作流程和患者-临床医生沟通方面显示出前景。然而,缺乏对胸外科围手术期患者教育的可行性评估。目的:本研究旨在评估中英文胸外科围手术期患者教育中使用ChatGPT的适宜性和全面性。方法:本研究于2023年2月进行。根据指南和临床经验,编制了37个胸外科围手术期患者教育问题。每个问题都向ChatGPT进行了两组查询,一组用英文,另一组用中文。ChatGPT生成的回复由经验丰富的胸外科医生根据对电子信息平台上患者问题的假设回复草稿,分别评估其适当性和全面性。对于合格的回应,至少需要80%的审稿人认为它是适当的,50%的审稿人认为它是全面的。采用非配对卡方检验或Fisher精确检验进行统计分析,显著性水平为:37个常见问题涵盖疾病信息、诊断程序、围手术期并发症、治疗措施、疾病预防和围手术期护理注意事项等主题。在中英文语境中,37个回答中有34个(92%)在适当性和全面性方面都是合格的。其余3个(8%)回答在这两种情况下是不合格的。不合格反应主要涉及疾病症状和手术相关并发症症状的诊断。在这两种情况下,将答复确定为不合格的原因是相似的。差异无统计学意义(34/ 37,92% vs 34/ 37,92%;P=.99)。结论:本初步研究证明了在中英文背景下使用ChatGPT进行胸外科围手术期患者教育的潜在可行性。ChatGPT有望在围手术期提高患者满意度,减少焦虑,提高依从性。在未来,将人工智能与人类审查相结合,在患者提供知情同意后进行患者教育和健康咨询,将有显著的潜在应用。

Background: In recent years, HIV infection in students has been an ongoing concern worldwide. A large number of articles have been published; however, statistical analysis of the data presented in these publications is lacking.
Objective: This study aimed to detect and analyze emerging trends and collaborative networks in research on HIV/AIDS among students.
Methods: Research publications on HIV/AIDS among students from 1985 to 2022 were collected from the Web of Science Core Collection. A topic search was used for this study, and articles in English were included. CiteSpace was used to generate visual networks of countries/regions, institutions, references, and keywords. Citation analysis was used to discover milestones in the field and trace the roots of the knowledge base. Keyword analysis was used to detect research hotspots and predict future trends.
Results: A total of 2726 publications met the inclusion criteria. Over the past 38 years, the number of publications annually has been on the rise overall. The United States had the highest number of publications (n=1303) and the highest centrality (0.91). The University of California system was the core institution. The main target population of studies on HIV/AIDS among students were medical and university students. These studies focused on students' knowledge, attitudes, risk behaviors, and education about HIV/AIDS. The recent bursting keywords (gay, sexual health, adherence, barriers, mental health, HIV testing, stigma, and antiretroviral therapy) revealed research trends and public interest on this topic.
Conclusions: This study identified countries/regions and institutions contributing to the research area of HIV/AIDS among students and revealed research hotspots and emerging trends. The field of research on HIV/AIDS among students was growing rapidly. The United States was at the center, and the University of California system was the core institution. However, academic collaboration should be strengthened. Future research may focus on exploring gay students, sexual health, adherence, barriers, mental health, HIV testing, stigma, and antiretroviral therapy.
背景:近年来,学生HIV感染一直是全球关注的问题。发表了大量文章;然而,缺乏对这些出版物中提供的数据的统计分析。目的:本研究旨在发现和分析学生中HIV/AIDS研究的新趋势和合作网络。方法:从Web of Science Core Collection中收集1985 ~ 2022年学生HIV/AIDS的研究出版物。本研究采用主题检索,纳入英文文章。使用CiteSpace生成国家/地区、机构、参考文献和关键词的可视化网络。引文分析被用来发现该领域的里程碑,并追踪知识库的根源。关键词分析法用于发现研究热点,预测未来趋势。结果:共有2726篇文献符合纳入标准。在过去的38年里,每年的出版物数量总体上呈上升趋势。美国的出版物数量最多(n=1303),中心性最高(0.91)。加州大学系统是核心机构。在学生中进行艾滋病毒/艾滋病研究的主要目标人群是医科学生和大学生。这些研究集中在学生对HIV/AIDS的知识、态度、风险行为和教育方面。最近爆发的关键词(同性恋、性健康、依从性、障碍、心理健康、艾滋病毒检测、耻辱和抗逆转录病毒治疗)揭示了这一主题的研究趋势和公众兴趣。结论:本研究确定了在学生艾滋病研究领域做出贡献的国家/地区和机构,揭示了研究热点和新兴趋势。学生中关于艾滋病毒/艾滋病的研究领域正在迅速发展。美国处于中心,加州大学系统是核心机构。但是,应该加强学术合作。未来的研究可能会集中在探索同性恋学生、性健康、依从性、障碍、心理健康、艾滋病毒检测、耻辱和抗逆转录病毒治疗上。

<p><strong>Background: </strong>Tracheal intubation is a life-saving intervention, and optimizing the patient's head and neck position for the best glottic view is a crucial step that accelerates the procedure. The left head rotation maneuver has been recently described as an innovative alternative to the traditional sniffing position used for tracheal intubation with marked improvement in glottic visualization.</p><p><strong>Objective: </strong>This study compared the glottic view and intubating conditions in the sniffing position versus left head rotation during direct laryngoscopy.</p><p><strong>Methods: </strong>This randomized, open-label clinical trial enrolled 52 adult patients admitted to Baguio General Hospital and Medical Center from September 2020 to January 2021 for an elective surgical procedure requiring tracheal intubation under general anesthesia. Intubation was done using a 45° left head rotation in the experimental group (n=26), while the control group (n=26) was intubated using the conventional sniffing position. Glottic visualization and intubation difficulty with the two procedures were assessed using the Cormack-Lehane grade and Intubation Difficulty Scale, respectively. Successful intubation is measured by observing a capnographic waveform in the end-tidal CO<sub>2</sub> monitor after placement of the endotracheal tube.</p><p><strong>Results: </strong>There was no statistically significant difference in the Cormack-Lehane grade, with 85% (n=44) of patients classified under grades 1 (n=11 and n=15) and 2 (n=11 and n=7) in the left head rotation and sniffing position groups, respectively. In addition, there were no statistically significant differences in the Intubation Difficulty Scale scores of patients intubated with left head rotation or sniffing position; 30.7% (n=8) of patients in both groups were easily intubated, while 53.8% (n=14) in left head rotation and 57.6% (n=15) in sniffing position groups were intubated with slight difficulty. Similarly, there were no significant differences between the 2 techniques in any of the 7 parameters of the Intubation Difficulty Scale, although numerically fewer patients required the application of additional lifting force (n=7, 26.9% vs n=11, 42.3%) or laryngeal pressure (n=3, 11.5% vs n=7, 26.9%) when intubated with left head rotation. The intubation success rate with left head rotation was 92.3% versus 100% in the sniffing position, but this difference was not statistically significant.</p><p><strong>Conclusions: </strong>Left head rotation produces comparable laryngeal exposure and intubation ease to the conventional sniffing position.

背景:气管插管是一种挽救生命的干预措施,优化患者的头颈部位置以获得最佳声门视图是加速手术的关键步骤。左侧头部旋转机动最近被描述为一种创新的替代方案,传统的嗅探位置用于气管插管,声门可见性显著改善。目的:比较直接喉镜下吸气位与左旋头时的声门视点和插管情况。方法:这项随机、开放标签的临床试验招募了2020年9月至2021年1月在碧瑶总医院和医疗中心住院的52名成人患者,他们在全身麻醉下接受了气管插管的选择性外科手术。实验组(n=26)采用头部左旋45°插管,对照组(n=26)采用常规嗅探体位插管。分别采用Cormack-Lehane分级和插管困难量表评估两种方法的声门可见性和插管困难。插管成功与否是通过观察置管后潮汐末CO2监测仪的二氧化碳波形来衡量的。结果:两组患者Cormack-Lehane评分差异无统计学意义,左侧头旋体位组有85% (n=44)的患者分为1级(n=11、n=15)和2级(n=11、n=7)。另外,采用左旋头位和吸气位插管患者的插管困难量表评分差异无统计学意义;两组患者插管容易者占30.7% (n=8),左旋头组插管困难者占53.8% (n=14),嗅位组插管困难者占57.6% (n=15)。同样,在插管困难量表的7个参数中,两种技术之间没有显着差异,尽管在左侧头部旋转插管时需要施加额外的举升力(n=7, 26.9% vs n=11, 42.3%)或喉压(n=3, 11.5% vs n=7, 26.9%)的患者数量较少。左旋头插管成功率为92.3%,而吸气位插管成功率为100%,但差异无统计学意义。结论:与传统的嗅探体位相比,左旋头可使喉部暴露和插管更加容易。因此,对于不能在嗅探位置插管的患者,特别是在没有先进技术(如视频喉镜和柔性支气管镜)的医院,如本研究中的情况,左头部旋转可能是一种替代方法。然而,由于我们的样本量很小,因此有必要对更大的研究人群进行研究,以确定我们的发现的普遍性。此外,我们观察到麻醉师对左头部旋转技术的熟悉程度不足,随着从业者对技术的熟悉程度提高,插管成功率可能会提高。试验注册:国际标准随机对照试验号(ISRCTN)ISRCTN23442026;https://www.isrctn.com/ISRCTN23442026。

Public health research plays a critical role in strengthening health systems and improving their performance and impact. However, scholarly production in public health coming from the Eastern Mediterranean Region (EMR) remains well below the world average and lacks a tangible growth trend over time. During the seventh Eastern Mediterranean Public Health Network Regional Conference, a roundtable session brought together a panel of public health experts representing Global Health Development/Eastern Mediterranean Public Health Network affiliates, universities or academia, and research institutions from the region, where they shared insights on the current situation of public health research; challenges and barriers to research facing the different countries in the EMR and the region in general; and how research agendas, productivity, and quality can be supported through strengthening research capacity in the region. Although the region is diverse in terms of health system capacity and socioeconomic development, several common challenges were identified, including a lack of strategic prioritization to guide health research, insufficient funding, ineffective transfer of knowledge to policy and practice, limited availability of research facilities, and limited national and international research collaboration. Occupied countries and countries in a state of conflict, such as Palestine, face additional barriers, such as personal and social security, lack of control of borders and natural resources, travel and movement restrictions, and confidentiality challenges because of the continuing war conditions and occupation. However, there have been success stories in the EMR regarding research publications and their positive and effective impact on policy and decision-makers. To improve research resilience and public health care in the region, a collaborative approach involving institutions, policymakers, and relevant stakeholders is critical.

<p><strong>Background: </strong>Identifying advanced (stages 4 and 5) chronic kidney disease (CKD) cohorts in clinical databases is complicated and often unreliable. Accurately identifying these patients can allow targeting this population for their specialized clinical and research needs.</p><p><strong>Objective: </strong>This study was conducted as a system-based strategy to identify all prevalent Veterans with advanced CKD for subsequent enrollment in a clinical trial. We aimed to examine the prevalence and accuracy of conventionally used diagnosis codes and estimated glomerular filtration rate (eGFR)-based phenotypes for advanced CKD in an electronic health record (EHR) database. We sought to develop a pragmatic EHR phenotype capable of improving the real-time identification of advanced CKD cohorts in a regional Veterans health care system.</p><p><strong>Methods: </strong>Using the Veterans Affairs Informatics and Computing Infrastructure services, we extracted the source cohort of Veterans with advanced CKD based on a combination of the latest eGFR value ≤30 ml·min<sup>-1</sup>·1.73 m<sup>-2</sup> or existing International Classification of Diseases (ICD)-10 diagnosis codes for advanced CKD (N18.4 and N18.5) in the last 12 months. We estimated the prevalence of advanced CKD using various prior published EHR phenotypes (ie, advanced CKD diagnosis codes, using the latest single eGFR <30 ml·min<sup>-1</sup>·1.73 m<sup>-2</sup>, utilizing two eGFR values) and our operational EHR phenotypes of a high-, intermediate-, and low-risk advanced CKD cohort. We evaluated the accuracy of these phenotypes by examining the likelihood of a sustained reduction of eGFR <30 ml·min<sup>-1</sup>·1.73 m<sup>-2</sup> over a 6-month follow-up period.</p><p><strong>Results: </strong>Of the 133,756 active Veteran enrollees at North Florida/South Georgia Veterans Health System (NF/SG VHS), we identified a source cohort of 1759 Veterans with advanced nondialysis CKD. Among these, 1102 (62.9%) Veterans had diagnosis codes for advanced CKD; 1391(79.1%) had the index eGFR <30 ml·min<sup>-1</sup>·1.73 m<sup>-2</sup>; and 928 (52.7%), 480 (27.2%), and 315 (17.9%) Veterans had high-, intermediate-, and low-risk advanced CKD, respectively. The prevalence of advanced CKD among Veterans at NF/SG VHS varied between 1% and 1.5% depending on the EHR phenotype. At the 6-month follow-up, the probability of Veterans remaining in the advanced CKD stage was 65.3% in the group defined by the ICD-10 codes and 90% in the groups defined by eGFR values. Based on our phenotype, 94.2% of high-risk, 71% of intermediate-risk, and 16.1% of low-risk groups remained in the advanced CKD category.</p><p><strong>Conclusions: </strong>While the prevalence of advanced CKD has limited variation between different EHR phenotypes, the accuracy can be improved by utilizing two eGFR values in a stratified manner.

Accurately identifying these patients can allow targeting this population for their specialized clinical and research needs.</p><p><strong>Objective: </strong>This study was conducted as a system-based strategy to identify all prevalent Veterans with advanced CKD for subsequent enrollment in a clinical trial. We aimed to examine the prevalence and accuracy of conventionally used diagnosis codes and estimated glomerular filtration rate (eGFR)-based phenotypes for advanced CKD in an electronic health record (EHR) database. We sought to develop a pragmatic EHR phenotype capable of improving the real-time identification of advanced CKD cohorts in a regional Veterans health care system.</p><p><strong>Methods: </strong>Using the Veterans Affairs Informatics and Computing Infrastructure services, we extracted the source cohort of Veterans with advanced CKD based on a combination of the latest eGFR value ≤30 ml·min<sup>-1</sup>·1.73 m<sup>-2</sup> or existing International Classification of Diseases (ICD)-10 diagnosis codes for advanced CKD (N18.4 and N18.5) in the last 12 months. We estimated the prevalence of advanced CKD using various prior published EHR phenotypes (ie, advanced CKD diagnosis codes, using the latest single eGFR <30 ml·min<sup>-1</sup>·1.73 m<sup>-2</sup>, utilizing two eGFR values) and our operational EHR phenotypes of a high-, intermediate-, and low-risk advanced CKD cohort. We evaluated the accuracy of these phenotypes by examining the likelihood of a sustained reduction of eGFR <30 ml·min<sup>-1</sup>·1.73 m<sup>-2</sup> over a 6-month follow-up period.</p><p><strong>Results: </strong>Of the 133,756 active Veteran enrollees at North Florida/South Georgia Veterans Health System (NF/SG VHS), we identified a source cohort of 1759 Veterans with advanced nondialysis CKD. Among these, 1102 (62.9%) Veterans had diagnosis codes for advanced CKD; 1391(79.1%) had the index eGFR <30 ml·min<sup>-1</sup>·1.73 m<sup>-2</sup>; and 928 (52.7%), 480 (27.2%), and 315 (17.9%) Veterans had high-, intermediate-, and low-risk advanced CKD, respectively. The prevalence of advanced CKD among Veterans at NF/SG VHS varied between 1% and 1.5% depending on the EHR phenotype. At the 6-month follow-up, the probability of Veterans remaining in the advanced CKD stage was 65.3% in the group defined by the ICD-10 codes and 90% in the groups defined by eGFR values. Based on our phenotype, 94.2% of high-risk, 71% of intermediate-risk, and 16.1% of low-risk groups remained in the advanced CKD category.</p><p><strong>Conclusions: </strong>While the prevalence of advanced CKD has limited variation between different EHR phenotypes, the accuracy can be improved by utilizing two eGFR values in a stratified manner.
