Abstract

Introduction: There are limited real-world data on outcomes in patients with non-cystic fibrosis bronchiectasis (NCFBE). This study assessed clinical characteristics and survival in patients with NCFBE by baseline exacerbation rate.

Methods: Patients with bronchiectasis (≥ 1 inpatient or ≥ 2 outpatient claims with a bronchiectasis diagnosis code, or one outpatient claim with bronchiectasis code and a chest computed tomography scan) were from the 100% Medicare Fee-for-Service database (Jan 2014-Dec 2020). Patients had continuous enrollment ≥ 12 months pre-index (baseline) and post-index (follow-up), with index a random bronchiectasis claim preceded by ≥ 12 months bronchiectasis history. Patients with cystic fibrosis were excluded. Patients were stratified by exacerbations during baseline (0, 1, or ≥ 2). Follow-up exacerbation rate and all-cause mortality were assessed. Controls were identified using a multistep direct matching approach. Time to death from index was estimated by Kaplan-Meier analyses.

Results: Exacerbation analysis included 92,529 patients with NCFBE and 92,529 matched controls. Exacerbations were common (43% had ≥ 1 exacerbation), with patients with more baseline exacerbations more likely to have ≥ 2 exacerbations during follow-up (11.4%, 24.2%, and 46.8% of patients with 0, 1, and ≥ 2 baseline exacerbations, respectively). Survival analysis included 110,298 patients with NCFBE and 110,298 controls. Time to death was shorter in patients with more baseline exacerbations (P < 0.0001). Five-year survival was 55.3%, 62.6%, and 65.4% for patients with ≥ 2, 1, and 0 baseline exacerbations, respectively, compared with 64.1% for controls.

Conclusions: In these patients with NCFBE, exacerbations were common. History of exacerbations was associated with future exacerbations and increased all-cause mortality.

按基线恶化率分列的美国医疗保险非囊性纤维化支气管扩张症患者的生存结果。

导言：有关非囊性纤维化支气管扩张症（NCFBE）患者疗效的实际数据非常有限。本研究根据基线恶化率评估了非囊性纤维化支气管扩张症患者的临床特征和存活率：支气管扩张症患者（≥1次住院或≥2次门诊索赔中包含支气管扩张症诊断代码，或1次门诊索赔中包含支气管扩张症代码和胸部计算机断层扫描）来自100%医疗保险付费服务数据库（2014年1月-2020年12月）。患者在索引前（基线）和索引后（随访）连续注册时间≥ 12 个月，索引为随机支气管扩张索赔，且支气管扩张病史≥ 12 个月。囊性纤维化患者除外。根据基线期间的病情加重情况对患者进行分层（0、1 或≥ 2）。评估随访加重率和全因死亡率。对照组采用多步骤直接匹配法确定。通过 Kaplan-Meier 分析法估算了从发病到死亡的时间：结果：病情加重分析包括 92,529 例 NCFBE 患者和 92,529 例匹配对照。病情恶化很常见（43%的患者病情恶化≥1次），基线病情恶化较多的患者在随访期间病情恶化≥2次的可能性更大（基线病情恶化为0、1和≥2次的患者分别占11.4%、24.2%和46.8%）。生存分析包括 110,298 名 NCFBE 患者和 110,298 名对照组患者。基线病情加重次数越多的患者死亡时间越短（P 结论：基线病情加重次数越多的患者死亡时间越短）：在这些 NCFBE 患者中，病情加重很常见。病情加重史与未来病情加重和全因死亡率增加有关。

期刊介绍： Aims and Scope Pulmonary Therapy is an international, open access, peer-reviewed (single-blind), and rapid publication journal. The scope of the journal is broad and will consider all scientifically sound research from pre-clinical, clinical (all phases), observational, real-world, and health outcomes research around the use of pulmonary therapies, devices, and surgical techniques. Areas of focus include, but are not limited to: asthma; chronic obstructive pulmonary disease; idiopathic pulmonary fibrosis; pulmonary hypertension; cystic fibrosis; lung cancer; respiratory tract disorders; allergic rhinitis and other respiratory allergies; influenza, pneumococcal infection, respiratory syncytial virus and other respiratory infections; and inhalers and other device therapies. The journal is of interest to a broad audience of pharmaceutical and healthcare professionals and publishes original research, reviews, case reports/series, trial protocols and short communications such as commentaries and editorials. Pulmonary Therapy will consider all scientifically sound research be it positive, confirmatory or negative data. Submissions are welcomed whether they relate to an international and/or a country-specific audience, something that is crucially important when researchers are trying to target more specific patient populations. This inclusive approach allows the journal to assist in the dissemination of quality research, which may be considered of insufficient interest by other journals. Rapid Publication The journal’s publication timelines aim for a rapid peer review of 2 weeks. If an article is accepted it will be published 3–4 weeks from acceptance. The rapid timelines are achieved through the combination of a dedicated in-house editorial team, who manage article workflow, and an extensive Editorial and Advisory Board who assist with peer review. This allows the journal to support the rapid dissemination of research, whilst still providing robust peer review. Combined with the journal’s open access model this allows for the rapid, efficient communication of the latest research and reviews, fostering the advancement of pulmonary therapies. Open Access All articles published by Pulmonary Therapy are open access. Personal Service The journal’s dedicated in-house editorial team offer a personal “concierge service” meaning authors will always have an editorial contact able to update them on the status of their manuscript. The editorial team check all manuscripts to ensure that articles conform to the most recent COPE, GPP and ICMJE publishing guidelines. This supports the publication of ethically sound and transparent research. Digital Features and Plain Language Summaries Pulmonary Therapy offers a range of additional features designed to increase the visibility, readership and educational value of the journal’s content. Each article is accompanied by key summary points, giving a time-efficient overview of the content to a wide readership. Articles may be accompanied by plain language summaries to assist readers who have some knowledge of, but not in-depth expertise in, the area to understand the scientific content and overall implications of the article. The journal also provides the option to include various types of digital features including animated abstracts, video abstracts, slide decks, audio slides, instructional videos, infographics, podcasts and animations. All additional features are peer reviewed to the same high standard as the article itself. If you consider that your paper would benefit from the inclusion of a digital feature, please let us know. Our editorial team are able to create high-quality slide decks and infographics in-house, and video abstracts through our partner Research Square, and would be happy to assist in any way we can. For further information about digital features, please contact the journal editor (see ‘Contact the Journal’ for email address), and see the ‘Guidelines for digital features and plain language summaries’ document under ‘Submission guidelines’. For examples of digital features please visit our showcase page https://springerhealthcare.com/expertise/publishing-digital-features/ Publication Fees Upon acceptance of an article, authors will be required to pay the mandatory Rapid Service Fee of €4500/ $5100/ £3650. The journal will consider fee discounts and waivers for developing countries and this is decided on a case by case basis. Peer Review Process Upon submission, manuscripts are assessed by the editorial team to ensure they fit within the aims and scope of the journal and are also checked for plagiarism. All suitable submissions are then subject to a comprehensive single-blind peer review. Reviewers are selected based on their relevant expertise and publication history in the subject area. The journal has an extensive pool of editorial and advisory board members who have been selected to assist with peer review based on the afore-mentioned criteria. At least two extensive reviews are required to make the editorial decision, with the exception of some article types such as Commentaries, Editorials, and Letters which are generally reviewed by one member of the Editorial Board. Where reviewer recommendations are conflicted, the editorial board will be contacted for further advice and a presiding decision. Manuscripts are then either accepted, rejected or authors are required to make major or minor revisions (both reviewer comments and editorial comments may need to be addressed). Once a revised manuscript is re-submitted, it is assessed along with the responses to reviewer comments and if it has been adequately revised it will be accepted for publication. Accepted manuscripts are then copyedited and typeset by the production team before online publication. Appeals against decisions following peer review are considered on a case-by-case basis and should be sent to the journal editor. Preprints We encourage posting of preprints of primary research manuscripts on preprint servers, authors’ or institutional websites, and open communications between researchers whether on community preprint servers or preprint commenting platforms. Posting of preprints is not considered prior publication and will not jeopardize consideration in our journals. Authors should disclose details of preprint posting during the submission process or at any other point during consideration in one of our journals. Once the manuscript is published, it is the author’s responsibility to ensure that the preprint record is updated with a publication reference, including the DOI and a URL link to the published version of the article on the journal website.
