    从经济学角度分析医疗改革。首先,提供医疗保健的经济理由在于,知道那些没有经济能力的人将能够获得医疗服务。然而,这并不能解释为什么他们应该享有相同的服务质量。在实践中,即使在高收入国家,愿意并有能力付费的患者往往更容易获得专科服务。其次,分工并没有提高医疗保健的效率,因为医疗服务是由拥有自主权的专业人员提供的。然而,通过使用临床路径将流程标准化,并将服务从医生转移到护士和技术人员,可以提高效率。第三,成本效益分析正被用于决定将医药产品列入国家处方集,但定价和处方仍然是特殊的。最后,基于此框架对日本的医疗体系进行了分析。
    Healthcare reform is analyzed from an economic perspective. First, the economic rationale for providing access to healthcare lies in the benefit from knowing that those without means would be able to access health services. However, this does not explain why they should be entitled to the same quality of service. In practice, even in high-income countries, patients who are willing and able to pay tend to have better access to specialist services. Secondly, the division of labor has not increased efficiency in healthcare because health services are provided by professionals who have autonomy. However, efficiency can be increased by standardizing the process with clinical pathways and shifting service delivery from physicians to nurses and technicians. Thirdly, cost-effectiveness analysis is being used to making decisions on listing pharmaceutical products in the national formulary, but pricing and prescribing have continued to be made idiosyncratically. Lastly, Japan\'s healthcare system is analyzed based on this framework.

    背景:医疗保健系统正在转变为使用数据驱动和研究知情方法来实现持续改进的学习型卫生系统。这些方法之一是使用临床路径,这些工具可以使特定人群的护理标准化并提高医疗质量。评估临床路径的成熟度是必要的,以告知路径开发团队和卫生系统决策者所需的路径修订或实施支持。为了改善发展,实施,以及省级临床路径的可持续性,我们建立了临床路径成熟度评估矩阵.探索矩阵的初始内容和面形效度,我们用它来评估萨斯喀彻温省卫生部门的一个病例路径,加拿大。
    方法:通过使用迭代的基于共识的流程,我们收集了包括患者和家庭伙伴在内的利益相关者的反馈,政策制定者,临床医生,和质量改进专家,排名,保留,或删除草案矩阵的启用符和子启用符。我们在当地试点地区的初级保健慢性疼痛路径(CPP)上测试了矩阵,并根据CPP开发团队负责人的反馈修改了矩阵。
    结果:最终矩阵包含五个使能者(即,设计,所有权和执行者,基础设施,绩效管理,和文化),20个子推动者,和每个子启用器的三个轨迹定义。为六个子启用者创建了补充文件。CPP在40个可能的成熟点中得到15分。尽管该途径在设计推动者中得分最高(10/12),这需要在几个方面给予更多关注,特别是所有权和执行者以及绩效管理推动者,每个得分为零。此外,基础设施和文化推动者得了2/4和3/8分,分别。CPP的这些领域需要改进,以提高CPP的整体成熟度。
    结论:我们开发了临床路径成熟度矩阵来评估临床路径的开发和实施的各个维度。这项初步工作的目标是开发和验证一种工具,以评估新的或现有途径的成熟度和准备情况,并跟踪途径的修订和改进。
    BACKGROUND: Healthcare systems are transforming into learning health systems that use data-driven and research-informed approaches to achieve continuous improvement. One of these approaches is the use of clinical pathways, which are tools to standardize care for a specific population and improve healthcare quality. Evaluating the maturity of clinical pathways is necessary to inform pathway development teams and health system decision makers about required pathway revisions or implementation supports. In an effort to improve the development, implementation, and sustainability of provincial clinical pathways, we developed a clinical pathways maturity evaluation matrix. To explore the initial content and face validity of the matrix, we used it to evaluate a case pathway within a provincial health authority in Saskatchewan, Canada.
    METHODS: By using iterative consensus-based processes, we gathered feedback from stakeholders including patient and family partners, policy makers, clinicians, and quality improvement specialists, to rank, retain, or remove enablers and sub-enablers of the draft matrix. We tested the matrix on the Chronic Pain Pathway (CPP) for primary care in a local pilot area and revised the matrix based on feedback from the CPP development team leader.
    RESULTS: The final matrix contains five enablers (i.e., Design, Ownership and Performer, Infrastructure, Performance Management, and Culture), 20 sub-enablers, and three trajectory definitions for each sub-enabler. Supplemental documents were created for six sub-enablers. The CPP scored 15 out of 40 possible points of maturity. Although the pathway scored highest in the Design enabler (10/12), it requires more attention in several areas, specifically the Ownership and Performer and the Performance Management enablers, each of which scored zero. Additionally, the Infrastructure and Culture enablers scored 2/4 and 3/8 points, respectively. These areas of the CPP are in need of improvement in order to enhance the overall maturity of the CPP.
    CONCLUSIONS: We developed a clinical pathways maturity matrix to evaluate the various dimensions of clinical pathways\' development and implementation. The goals of this initial work were to develop and validate a tool to assess the maturity and readiness of new or existing pathways and to track pathways\' revisions and improvements.

    背景:为了支持护理时的临床决策,必须提供基于标准操作程序(SOP)的“最佳下一步”和实际准确的患者数据。要做到这一点,文本SOP必须转换成可操作的临床算法,并与正在治疗的患者的数据相关联。对于这种联系,我们需要确切地知道临床医生在某个决策点需要哪些数据,以及这些数据是否可用。这些数据可能与SOP中使用的数据相同,或者可能集成了更广阔的视野。为了解决这些问题,我们从医师的角度检查了SOP使用的数据是否也是完整的,以进行情境决策.方法:我们选择了67例III期黑色素瘤患者,他们接受了辅助治疗,主要有前哨活检指征。首先,我们按照我们的临床算法对患者治疗进行了一步一步的模拟,这是基于医院特定的标准操作程序,使用我们队列的基于快速医疗保健互操作性资源(FHIR)的数据验证算法。第二,我们在算法中向10位皮肤肿瘤学家提出了三种不同的决策情况,专注于这个决策点使用的具体患者数据。结果进行了,分析,并与纯算法模拟进行了比较。结果:使用来自患者电子健康记录的数据,可以按照临床算法对黑色素瘤患者的治疗路径进行回顾性模拟。皮肤科医师随后的评估表明,与SOP使用的数据相比,三个决策点使用的数据的完整性在84.6%至100.0%之间。在一个决策点,缺少"患者年龄(初诊时)"和"首次诊断日期"的数据.结论:我们的决策点所需的数据可在基于FHIR的数据集中获得。此外,与医生在临床实践中所需的数据相比,SOP在决策点使用的数据以及临床算法几乎是完整的.这是进一步研究的重要前提,重点是在与所需患者数据集成的治疗过程中提出决策点。
    Background: To support clinical decision-making at the point of care, the \"best next step\" based on Standard Operating Procedures (SOPs) and actual accurate patient data must be provided. To do this, textual SOPs have to be transformed into operable clinical algorithms and linked to the data of the patient being treated. For this linkage, we need to know exactly which data are needed by clinicians at a certain decision point and whether these data are available. These data might be identical to the data used within the SOP or might integrate a broader view. To address these concerns, we examined if the data used by the SOP is also complete from the point of view of physicians for contextual decision-making. Methods: We selected a cohort of 67 patients with stage III melanoma who had undergone adjuvant treatment and mainly had an indication for a sentinel biopsy. First, we performed a step-by-step simulation of the patient treatment along our clinical algorithm, which is based on a hospital-specific SOP, to validate the algorithm with the given Fast Healthcare Interoperability Resources (FHIR)-based data of our cohort. Second, we presented three different decision situations within our algorithm to 10 dermatooncologists, focusing on the concrete patient data used at this decision point. The results were conducted, analyzed, and compared with those of the pure algorithmic simulation. Results: The treatment paths of patients with melanoma could be retrospectively simulated along the clinical algorithm using data from the patients\' electronic health records. The subsequent evaluation by dermatooncologists showed that the data used at the three decision points had a completeness between 84.6% and 100.0% compared with the data used by the SOP. At one decision point, data on \"patient age (at primary diagnosis)\" and \"date of first diagnosis\" were missing. Conclusions: The data needed for our decision points are available in the FHIR-based dataset. Furthermore, the data used at decision points by the SOP and hence the clinical algorithm are nearly complete compared with the data required by physicians in clinical practice. This is an important precondition for further research focusing on presenting decision points within a treatment process integrated with the patient data needed.

    背景:当21个瑞典县议会决定合作创建基于知识的管理的国家系统时,患者参与是强制性的.患者和近亲代表(PR)与医疗保健专业人员(HPR)共同制作了以人为本和有凝聚力的临床路径。在国家一级,关于医疗保健联合生产的研究很少。这项研究的目的是在瑞典全国医疗保健系统内共同生产基于知识的管理的临床路径时,从PR和HPR的角度探索患者参与的经验。
    方法:进行了定性研究。在2022年8月至2023年1月之间,使用半结构化访谈指南对9个PR和8个HPR的战略样本进行了单独访谈。我们使用归纳内容分析来分析数据。
    结果:确定了三个主要类别:(1)找到适当的患者代表性;(2)促进患者观点的工作方法;(3)患者观点在临床路径中的影响。
    结论:该研究证明了患者和亲属参与国家层面临床路径构建的重要性。这些结果为在国家层面上进一步研究患者参与提供了一个平台,并增加了关于患者在这一层面上的参与是否以及如何影响临床路径在微观层面上的实施的研究。以及在中观层面提供的支持。该研究有助于研究患者参与和共同生产的文献越来越多。
    背景:厄勒布罗县ID276,940。咨询意见是从瑞典伦理审查局(2021-05899-01)获得的。
    与患者和近亲代表共同制作指南和临床路径在国际医疗保健领域的不同层面日益受到重视。然而,关于患者参与国家层面的经验,几乎没有文献记载和探索。当瑞典启动基于知识的国家医疗保健管理系统时,患者参与是强制性的。医疗保健的知识管理是与创建,分享,使用和管理组织的知识和信息。瑞典的所有21个地区和政府都支持这一合作系统,该系统由具有患者代表的多专业国家工作组组成。这些小组开发临床路径,旨在加强协调,平等和有效的医疗保健。以人为本的临床路径描述了评估,诊断,对条件的规划和评估,例如对于髋部骨折的患者,或者充血性心力衰竭.该研究侧重于患者参与国家工作组的经验。我们采访了来自11个不同小组的9名患者代表和8名医疗保健专业代表。我们的研究结果表明,确定和找到适当的患者代表性的重要性,具有促进患者观点和影响临床路径的患者观点的工作方法。这项关于患者参与国家一级临床路径建设的研究有助于越来越多的关于共同生产知识支持的文献。研究结果强调了在国家一级继续发展有意义的患者参与的重要学习。这也引起了人们对联合生产的国家方法如何影响使用准则的地方级别的好奇心。
    BACKGROUND: When the 21 Swedish county councils decided to collaborate in the creation of a national system for knowledge-based management, patient participation was mandatory. Patient and next-of-kin representatives (PR) co-produced person-centred and cohesive clinical pathways together with healthcare professionals (HPR). Research on co-production in healthcare at the national level is scarce. The aim of this study is to explore experiences of patient participation from the perspectives of both PRs and HPRs when co-producing clinical pathways within the Swedish nationwide healthcare system for knowledge-based management.
    METHODS: A qualitative study was conducted. A strategic sample of nine PRs and eight HPRs were interviewed individually between August 2022 and January 2023 using a semi-structured interview guide. We analysed data using an inductive content analysis.
    RESULTS: Three main categories were identified: (1) Finding appropriate patient representativeness; (2) Working methods that facilitate a patient perspective; and (3) Influence of the patient perspective in the clinical pathways.
    CONCLUSIONS: The study demonstrates the importance of patient and next-of-kin participation in the construction of clinical pathways at the national level. The results provide a platform for further research on patient participation on the national level and add to studies on if and how patient participation on this level has an impact on how the clinical pathways are put into practice at the micro level, and the support provided at the meso level. The study contributes to the growing body of literature studying patient participation and co-production.
    BACKGROUND: Region Örebro County ID 276,940. An advisory opinion was obtained from the Swedish Ethical Review Authority (2021-05899-01).
    Co-production of guidelines and clinical pathways with patients and next-of-kin representatives is increasingly emphasised at different levels in healthcare internationally. However, little has been documented and explored regarding experiences of patient participation on a national level. Patient participation was mandatory when a national system for knowledge-based management of healthcare was launched in Sweden. Knowledge management of healthcare is the collection of methods relating to creating, sharing, using and managing the knowledge and information of an organization. All 21 of Sweden’s regions and the government have supported this collaborative system consisting of multi-professional national working groups with patient representatives. The groups develop clinical pathways aiming to enhance a coordinated, equal and effective healthcare. The person-centred clinical pathways describe assessment, diagnosis, planning and evaluation for a condition, for example for patients with a hip fracture, or congestive heart failure. The study focuses on experiences of patient participation in the national working groups. We interviewed nine patient representatives and eight healthcare professional representatives from eleven different groups. Our findings show the importance of identifying and finding appropriate patient representativeness, having working methods that facilitate a patient perspective and the patient perspective influencing the clinical pathways. This study on patient participation in the construction of clinical pathways at the national level contributes to the growing body of literature on co-production of knowledge support. The findings highlight important learning for the continued development of meaningful patient participation on the national level. It also raises curiosity on how the national approach with co-production influences local levels where the guidelines are used.

    增强手术后恢复(ERAS)方案在改善患者预后和降低普外科费用方面的成功得到了广泛认可。现在已经在骨科中开发了ERAS指南,并提出了以下建议。术前,患者应进行医学优化,重点是戒烟,教育,减少焦虑。术中,使用神经轴麻醉和周围神经阻滞等多模式和区域性治疗可促进当天出院。术后,早期营养与适当的血栓预防和早期动员至关重要.随着患者预后和满意度改善的证据继续存在,这些途径在优化骨科患者护理方面将被证明是无价的。
    The success of enhanced recovery after surgery (ERAS) protocols in improving patient outcomes and reducing costs in general surgery are widely recognized. ERAS guidelines have now been developed in orthopedics with the following recommendations. Preoperatively, patients should be medically optimized with a focus on smoking cessation, education, and anxiety reduction. Intraoperatively, using multimodal and regional therapies like neuraxial anesthesia and peripheral nerve blocks facilitates same-day discharge. Postoperatively, early nutrition with appropriate thromboprophylaxis and early mobilization are essential. As the evidence of their improvement in patient outcomes and satisfaction continues, these pathways will prove invaluable in optimizing patient care in orthopedics.

    背景:快速进化,复杂性,和肿瘤治疗的专业化使得医生根据最新和最好的证据提供护理具有挑战性。我们假设医生会使用基于证据的可信护理途径,如果它们易于使用并在护理点整合到临床工作流程中。
    方法:在大型综合护理提供系统中,我们召集临床专家来定义和更新药物治疗途径,将它们编码为与电子病历集成的在线图书馆中的流程图,传达了临床医生将为每位符合条件的患者使用这些途径的期望,并组合来自多个来源的数据,以了解一段时间的使用情况。
    结果:我们能够在两年内通过这些途径订购的合格方案的利用率达到>75%,>90%的个体肿瘤学家至少咨询过这种途径,尽管没有与途径使用相关的要求或外部激励措施。用户的反馈有助于改进和更新指南。
    结论:通过使我们的临床决策支持易于获得和可操作,我们发现,在让医生在治疗决策中咨询最新证据的目标方面,我们已经取得了相当大的进展。
    BACKGROUND: The rapid evolution, complexity, and specialization of oncology treatment makes it challenging for physicians to provide care based on the latest and best evidence. We hypothesized that physicians would use evidence-based trusted care pathways if they were easy to use and integrated into clinical workflow at the point of care.
    METHODS: Within a large integrated care delivery system, we assembled clinical experts to define and update drug treatment pathways, encoded them as flowcharts in an online library integrated with the electronic medical record, communicated expectations that clinicians would use these pathways for every eligible patient, and combined data from multiple sources to understand usage over time.
    RESULTS: We were able to achieve > 75% utilization of eligible protocols ordered through these pathways within two years, with > 90% of individual oncologists having consulted the pathway at least once, despite no requirements or external incentives associated with pathway usage. Feedback from users contributed to improvements and updates to the guidance.
    CONCLUSIONS: By making our clinical decision support easily accessible and actionable, we find that we have made considerable progress toward our goal of having physicians consult the latest evidence in their treatment decisions.

    BACKGROUND: We assess the impact of bone health clinical management in breast cancer (BC) patients receiving adjuvant endocrine therapy and design a personalized clinical pathway to reduce bone loss in an Italian research hospital.
    METHODS: The primary endpoint was to assess (through the process improvement organizational method) the clinical pathway that post-surgical BC patients prescribed with endocrine therapy undergo to prevent bone loss. The secondary endpoint was to design a personalized clinical pathway for a prompt implementation of guidelines, to assess and possibly prescribe antiresorptive therapy.
    RESULTS: During the first year of the execution of the new Diagnostic Therapeutic Assistance Pathway, a 60% increase in Dual-Energy X-ray Absorptiometry evaluations within 30 days and a 39.5% increase in antiresorptive therapy prescription within 90 days (since the prescription of endocrine therapy) were shown, thus increasing patients\' compliance.
    CONCLUSIONS: Case managers and bone health specialists in this context can improve patients\' adherence to therapies and bone health, helping physicians to expand their collaboration.

    MRI引导聚焦超声(MRgFUS)损伤是一种创新,安全有效的治疗,为微创立体定向神经外科领域提供了创新的发展。基于聚焦超声能量在全MR规划和热成像控制下的应用,单侧丘脑损伤,丘脑底核,苍白球用于治疗运动障碍,包括特发性震颤,帕金森病,和肌张力障碍.我们于2019年2月开始将该技术应用于运动障碍患者的治疗。作者开发了一种诊断治疗护理途径,本文提出并应用于使用中的标准临床实践的解释。该项目是应用不同方法的结果,如卫生技术评估(HTA),力量,弱点,机会和威胁分析(SWOT)和Demin-Plan,Do,Check,行动(PDCA)循环。该项目的目的是标准化MRgFUS诊断-治疗途径(DTP),描述其应用和不同阶段的适当性(患者选择,干预阶段和随访)。这里,我们详细描述了从2019年至今在610例运动障碍患者中应用DTP的经验.
    MRI-guided focused ultrasound (MRgFUS) lesioning is an innovative, safe and effective treatment which provides an innovative development in the field of minimally invasive stereotactic neurosurgery. Based on the application of focused ultrasound energy under full MR planning and thermal imaging control, unilateral lesioning of the thalamus, subthalamic nucleus, and globus pallidus is indicated for the treatment of movement disorders, including essential tremor, Parkinson\'s disease, and dystonia. We started to apply this technique in February 2019 for the treatment of patients with movement disorders. The authors developed a diagnostic therapeutic care pathway, which is herewith proposed and applied as an explication of standard clinical practice in use. The project was the result of the application of different methods such as Health Technology Assessment (HTA), Strengths, Weaknesses, Opportunities and Threats analysis (SWOT) and Demin -Plan, Do, Check, Act (PDCA) cycle. The aim of this project was to standardize the MRgFUS diagnostic-therapeutic pathway (DTP), describe its application and the appropriateness of different phases (patient selection, intervention phase and follow-up). Here, we described in detail our experience in the DTP application from 2019 up to now in 610 patients with movement disorders.

    背景与目的:医院获得性静脉血栓栓塞(VTEs)是常见且可预防的。昆士兰州健康VTE预防指南,2018年开发,为风险评估提供指导,以及预防和治疗住院患者的抗凝处方。目前,对消化内科患者的建议有限。这项研究调查了VTE风险评估的完成情况,以及VTE预防方案的适当性,符合昆士兰州胃肠病患者健康指南。根据VTE风险和出血风险评估VTE预防方案的质量和安全性。方法:通过随机抽取澳大利亚三级医院收治的消化内科患者进行回顾性研究,从2019年5月1日至2020年5月1日,确定VTE风险评估和血栓预防处方是否符合全州VTE指南。使用改良Caprini和HASBLED评分评估血栓预防的质量和安全性,以及随后的血栓预防相关并发症。结果:在94例患者中,68没有血栓预防的禁忌症。在这68名患者中,32人(47%)在其临床记录中没有记录VTE风险评估,并且在住院期间没有规定任何血栓预防。低VTE风险患者的血栓预防处方之间没有显着差异,与中度至高度VTE风险相比(P=0.075)。随着HASBLED出血风险评分的增加,血栓预防处方有减少的趋势,和中度-高度出血风险的患者不太可能被规定的血栓预防(P=.006)。没有发现与血栓预防相关的并发症。结论:所有患者都必须有明确记录的风险评估,并根据最佳实践指南进行血栓预防。预防静脉血栓栓塞的处方应继续个体化,对每位患者进行全面评估。
    Background and objective: Hospital acquired venous thromboembolisms (VTEs) are common and preventable. The Queensland Health VTE prophylaxis guidelines, developed in 2018, provide guidance for risk assessment, and prescribing of anticoagulation for prophylaxis and treatment of hospital inpatients. Currently, there are limited recommendations for gastroenterology patients. This study investigated the completion of VTE risk assessments, and the appropriateness of VTE prophylaxis regimens, in accordance with Queensland Health guidelines for gastroenterology patients. The quality and safety of VTE prophylaxis regimens was assessed based on their VTE risk and bleeding risk. Method: A retrospective study was conducted by obtaining a random sample of gastroenterology patients admitted to a tertiary Australian hospital, from 1st May 2019 and 1st May 2020, to determine the compliance of VTE risk assessment and thromboprophylaxis prescribing with state-wide VTE guidelines. The quality and safety of thromboprophylaxis was evaluated using the modified Caprini and HASBLED scores, and subsequent thromboprophylaxis-related complications. Results: Of the 94 patients reviewed, 68 did not have contraindications to thromboprophylaxis. Of these 68 patients, 32 (47%) had no VTE risk assessment recorded in their clinical records and were not prescribed any thromboprophylaxis during the hospitalization. There was no significant difference between thromboprophylaxis prescribing for patients with low VTE risk, compared to moderate to high VTE risk (P = .075). There was a trend for decrease in thromboprophylaxis prescribing as HASBLED bleeding risk score increased, and patients with moderate-high bleed risk were less likely to be prescribed thromboprophylaxis (P = .006). There were no thromboprophylaxis related complications identified. Conclusion: It is essential that all patients have a clearly documented risk assessment and are prescribed thromboprophylaxis according to best practice guidelines. The prescription of venous thromboembolism prophylaxis should continue to be individualized, with each patient assessed holistically.

    背景:通过应用于现实世界数据的临床路径推断框架,发现药物治疗处方模式及其与结果的统计关联。
    方法:我们使用2006年至2020年患有重度抑郁症(MDD)的退伍军人队列在我们的框架中应用机器学习步骤。门诊抗抑郁药药房填充,分配住院抗抑郁药物,急诊部门的访问,自我伤害,全因死亡率数据是从退伍军人事务部企业数据仓库中提取的。
    结果:我们的MDD队列由252,179名个体组成。在研究期间,有98,417例急诊科就诊,1016起自残案件,1,507人死于各种原因。在开始使用氟西汀当量为20-39mg的抗抑郁药的个体中,前十种处方模式占数据的69.3%。此外,我们发现结局与剂量变化之间存在关联.
    结论:对于在伊拉克和阿富汗服役的252,179名退伍军人,其电子病历中记录了随后的MDD,我们记录并描述了退伍军人健康管理局提供者实施的主要药物治疗处方模式.十种模式几乎占数据的70%。观察数据中抗抑郁药的使用与结果之间的关联可能会混淆。不良事件的数量少,尤其是那些与全因死亡率相关的,使我们的计算不精确。此外,我们的结果也是疾病和治疗的适应症.尽管有这些限制,我们证明了我们的框架在提供临床实践的操作洞察力方面的有用性,我们的结果强调了在治疗的临界点需要加强监测.
    BACKGROUND: To discover pharmacotherapy prescription patterns and their statistical associations with outcomes through a clinical pathway inference framework applied to real-world data.
    METHODS: We apply machine learning steps in our framework using a 2006 to 2020 cohort of veterans with major depressive disorder (MDD). Outpatient antidepressant pharmacy fills, dispensed inpatient antidepressant medications, emergency department visits, self-harm, and all-cause mortality data were extracted from the Department of Veterans Affairs Corporate Data Warehouse.
    RESULTS: Our MDD cohort consisted of 252,179 individuals. During the study period there were 98,417 emergency department visits, 1,016 cases of self-harm, and 1,507 deaths from all causes. The top ten prescription patterns accounted for 69.3% of the data for individuals starting antidepressants at the fluoxetine equivalent of 20-39 mg. Additionally, we found associations between outcomes and dosage change.
    CONCLUSIONS: For 252,179 Veterans who served in Iraq and Afghanistan with subsequent MDD noted in their electronic medical records, we documented and described the major pharmacotherapy prescription patterns implemented by Veterans Health Administration providers. Ten patterns accounted for almost 70% of the data. Associations between antidepressant usage and outcomes in observational data may be confounded. The low numbers of adverse events, especially those associated with all-cause mortality, make our calculations imprecise. Furthermore, our outcomes are also indications for both disease and treatment. Despite these limitations, we demonstrate the usefulness of our framework in providing operational insight into clinical practice, and our results underscore the need for increased monitoring during critical points of treatment.
