ABSTRACT

BACKGROUND: Cone beam computed tomography (CBCT)-guided bronchoscopic sampling of peripheral pulmonary lesions (PPLs) is associated with superior diagnostic outcomes. However, the added value of a robotic-assisted bronchoscopy platform in CBCT-guided diagnostic procedures is unknown. METHODS: We performed a retrospective review of 100 consecutive PPLs sampled using conventional flexible bronchoscopy under CBCT guidance (FB-CBCT) and 100 consecutive PPLs sampled using an electromagnetic navigation-guided robotic-assisted bronchoscopy platform under CBCT guidance (RB-CBCT). Patient demographics, PPL features, procedural characteristics, and procedural outcomes were compared between the 2 cohorts. RESULTS: Patient and PPL characteristics were similar between the FB-CBCT and RB-CBCT cohorts, and there were no significant differences in diagnostic yield (88% vs. 90% for RB-CBCT, P=0.822) or incidence of complications between the 2 groups. As compared with FB-CBCT cases, RB-CBCT cases were significantly shorter (median 58 min vs. 92 min, P<0.0001) and used significantly less diagnostic radiation (median dose area product 5114 µGy•m2 vs. 8755 µGy•m2, P<0.0001). CONCLUSION: CBCT-guided bronchoscopy with or without a robotic-assisted bronchoscopy platform is a safe and effective method for sampling PPLs, although the integration of a robotic-assisted platform was associated with significantly shorter procedure times and significantly less radiation exposure.

ABSTRACT

BACKGROUND AND OBJECTIVES: Patient experience narratives (narratives) are an increasingly important element of both measurement approaches and improvement efforts in healthcare. Prior studies show that narratives are considered by both clinicians and staff to be an appealing, meaningful, and credible form of evidence on performance. They also suggest that making concrete use of narratives within organizational settings to improve care can be complex and challenging. Our qualitative study was designed to explore how middle managers working in a health system's outpatient clinics value and use written narratives in their day-to-day work. METHODS: We conducted qualitative interviews with 20 middle managers working in 8 outpatient clinics. Interviews were fully transcribed, loaded into MAX-QDA software, and coded using thematic analysis techniques. Code reports were extracted and reanalyzed for subthemes related to the objectives of this paper. RESULTS: Middle managers across sites described valuing narratives as a tool to: enable better patient experience assessment by augmenting data from patient experience scores; deepen understanding of and relationships with patients; provide insight about operational issues; identify areas for needed improvement and potential solutions; and facilitate strategic work. They reported using narratives for a range of activities related to their roles as supervisors, such as focusing attention on positive practices and needed improvements, promoting deeper group learning, motivating change, reinforcing sense of purpose for staff, recognizing staff strengths and training needs, and inspiring transformational thinking. Finally, interviewees reported numerous specific quality improvement projects (both short- and longer-term) that were informed by narratives-for example, by identifying an issue to be addressed or by suggesting a workable solution. Together, these interviews suggest a collective "narrative about narratives" woven by these organizational actors-a story which illustrates how narratives are highly relevant for how middle managers derive meaning from their work, put organizational values such as responsive service provision into practice, and enact their roles as supervisors. CONCLUSIONS: Our results add to the nascent literature a detailed description of how narratives can be used both as a tool for middle managers in their leadership and supervisory roles, and as a blueprint for improvement work within outpatient settings. They also illuminate why patient experience scores may improve when narrative data are collected and used. Finally, our results suggest that for middle managers, perhaps "nothing is more powerful than words" because narratives function as both an insight provider and a compelling tool that adds direction and meaning to workplace endeavors.

ABSTRACT

Policy Points Patients' creative ideas may inform learning and innovation that improve patient-centered care. Routinely collected patient experience surveys provide an opportunity to invite patients to share their creative ideas for improvement. We develop and assess a methodological strategy that validates question wording designed to elicit creative ideas from patients. Health care organizations should consider how to report and use these data in health care delivery and quality improvement, and policymakers should consider promoting the use of narrative feedback to better understand and respond to patients' experiences. CONTEXT: Learning health systems (LHSs) have been promoted for a decade to achieve high-quality, patient-centered health care. Innovation driven by knowledge generated through day-to-day health care delivery, including patient insights, is critical to LHSs. However, the pace of translating patient insights into innovation is slow and effectiveness inadequate. This study aims to evaluate a method for systematically eliciting patients' creative ideas, examine the value of such ideas as a source of insight, and examine patients' creative ideas regarding how their experiences could be improved within the context of their own health systems. METHODS: The first stage of the study developed a survey and tested strategies for elicitation of patients' creative ideas with 600 patients from New York State. The second stage deployed the survey with the most generative open-ended question sequence within a health care system and involved analysis of 1,892 patients' responses, including 2,948 creative ideas. FINDINGS: Actionable, creative feedback was fostered by incorporating a request for transformative feedback into a sequence of narrative elicitation questions. Patients generate more actionable and creative ideas when explicitly invited to share such ideas, especially patients with negative health care experiences, those from minority racial/ethnic backgrounds, and those with chronic illness. The most frequently elicited creative ideas focused on solving challenges, proposing interventions, amplifying exceptional practices, and conveying hopes for the future. CONCLUSIONS: A valid and reliable method for eliciting creative ideas from patients can be deployed as part of routine patient experience surveys that include closed-ended survey items and open-ended narrative items in which patients share their experiences in their own words. The elicited creative ideas are promising for patient engagement and innovation efforts. This study highlights the benefits of engaging patients for quality improvement, offers a rigorously tested method for cultivating innovation using patient-generated knowledge, and outlines how creative ideas can enable organizational learning and innovation.

ABSTRACT

OBJECTIVE: To assess whether an online interactive report designed to facilitate interpretation of patients' narrative feedback produces change in ambulatory staff learning, behavior at the individual staff and practice level, and patient experience survey scores. DATA SOURCES AND SETTING: We studied 22 ambulatory practice sites within an academic medical center using three primary data sources: 333 staff surveys; 20 in-depth interviews with practice leaders and staff; and 9551 modified CG-CAHPS patient experience surveys augmented by open-ended narrative elicitation questions. STUDY DESIGN: We conducted a cluster quasi-experimental study, comparing 12 intervention and 10 control sites. At control sites, narratives were delivered free-form to site administrators via email; at intervention sites, narratives were delivered online with interactive tools for interpretation, accompanied by user training. We assessed control-versus-intervention site differences in learning, behavior, and patient experience scores. DATA COLLECTION: Staff surveys and interviews were completed at intervention and control sites, 9 months after intervention launch. Patient surveys were collected beginning 4 months pre-launch through 9 months post-launch. We used control-versus-intervention and difference-in-difference analyses for survey data and thematic analysis for interview data. PRINCIPAL FINDINGS: Interviews suggested that the interface facilitated narrative interpretation and use for improvement. Staff survey analyses indicated enhanced learning from narratives at intervention sites (29% over control sites' mean of 3.19 out of 5 across eight domains, p < 0.001) and greater behavior change at staff and practice levels (31% and 21% over control sites' means of 3.35 and 3.39, p < 0.001, respectively). Patient experience scores for interactions with office staff and wait time information increased significantly at intervention sites, compared to control sites (3.7% and 8.2%, respectively); however, provider listening scores declined 3.3%. CONCLUSIONS: Patient narratives presented through structured feedback reporting methods can catalyze positive changes in staff learning, promote behavior change, and increase patient experience scores in domains of non-clinical interaction.

ABSTRACT

BACKGROUND: Enthusiasm has grown about using patients' narratives-stories about care experiences in patients' own words-to advance organizations' learning about the care that they deliver and how to improve it, but studies confirming association have not been published. PURPOSE: We assessed whether primary care clinics that frequently share patients' narratives with their staff have higher patient experience survey scores. APPROACH: We conducted a 1-year study of 5,545 adult patients and 276 staff affiliated with nine clinics in one health system. We used multilevel models to analyze survey data from patients about their experiences and from staff about exposure to useful narratives. We examined staff confidence in own knowledge as a moderator because confidence can influence use of new information sources. RESULTS: Frequency of sharing useful narratives with staff was associated with patient experience scores for all measures, conditional on staff confidence in own knowledge ( p < .01). For operational measures (e.g., care coordination), increased sharing correlated with subsequently higher performance for more confident staff and lower performance or no difference for less confident staff, depending on measure. For relational measures (e.g., patient-provider communication), increased sharing correlated with higher scores for less confident staff and lower scores for more confident staff. CONCLUSION: Sharing narratives with staff frequently is associated with better patient experience survey scores, conditional on confidence in knowledge. PRACTICE IMPLICATIONS: Frequently sharing useful patient narratives should be encouraged as an organizational improvement strategy. However, organizations need to address how narrative feedback interacts with their staff's confidence to realize higher experience scores across domains.

ABSTRACT

PURPOSE OF REVIEW: Historically the sampling of peripheral lung lesions via bronchoscopy has suffered from inferior diagnostic outcomes relative to transthoracic needle aspiration, and neither a successful bronchoscopic navigation nor a promising radial ultrasonographic image of one's target lesion guarantees a successful biopsy. Fortunately, many of peripheral bronchoscopy's shortcomings - including an inability to detect and compensate for computed tomography (CT)-body divergence, and the absence of tool-in-lesion confirmation - are potentially remediable through the use of improved intraprocedural imaging techniques. RECENT FINDINGS: Recent advances in intraprocedural imaging, including the integration of cone beam CT, digital tomosynthesis, and augmented fluoroscopy into bronchoscopic procedures have yielded promising results. These advanced imaging modalities may improve the outcomes of peripheral bronchoscopy through the detection and correction of navigational errors, CT-body divergence, and malpositioned biopsy instruments. SUMMARY: The incorporation of advanced imaging is an essential step in the improvement of peripheral bronchoscopic procedures.

ABSTRACT

BACKGROUND: Severe Coronavirus Disease 2019 (COVID-19) infection is associated with prolonged intubation and its complications. Tracheal stenosis is one such complication that may require specialized surgical management. We aimed to describe the surgical management of post-COVID-19 tracheal stenosis. METHODS: This case series describes consecutive patients with tracheal stenosis from intubation for severe COVID-19 infection at our single, tertiary academic medical center between January 1st, 2021, and December 31st, 2021. Patients were included if they underwent surgical management with tracheal resection and reconstruction, or bronchoscopic intervention. Operative through six-month, symptom-free survival and histopathological analysis of resected trachea were reviewed. RESULTS: Eight patients are included in this case series. All patients are female, and most (87.5%) are obese. Five patients (62.5%) underwent tracheal resection and reconstruction (TRR), while three patients (38.5%) underwent non-resection-based management. Among patients who underwent TRR, six-month symptom free survival is 80%; one patient (20%) required tracheostomy after TRR due to recurrent symptoms. Two of the three (66.7%) of patients who underwent non-resection-based management experienced durable relief from symptoms of tracheal stenosis with tracheal balloon dilation, and the remaining patient required laser excision of tracheal tissue prior to experiencing symptomatic relief. CONCLUSIONS: The incidence of tracheal stenosis may increase as patients recover from severe COVID-19 infection requiring intubation. Management of tracheal stenosis with TRR is safe and effective, with comparable rates of success to TRR for non-COVID-19 tracheal stenosis. Non-resection-based management is an option to manage tracheal stenosis in patients with less severe stenosis or in poor surgical candidates.

ABSTRACT

Purpose: To evaluate findings after transbronchial lung cryobiopsy (TBLC) using intraprocedural cone-beam CT (CBCT) and follow-up chest CT examinations. Materials and Methods: A single-center, prospective cohort study was performed with 14 participants (mean age, 65 years ± 13 [SD]; eight male participants) undergoing CBCT-guided TBLC between August 2020 and February 2021 who underwent follow-up chest CT imaging. Intraprocedural CBCT and follow-up chest CT images were interpreted for changes compared with baseline CT images. Statistical analyses were performed using independent samples t test and analysis of variance. Results: A total of 62 biopsies were performed, with 48 in the field of view of CBCT immediately after biopsy. All 48 biopsy sites had evidence of postprocedural hemorrhage, and 17 (35%) had pneumatoceles at the biopsy site. Follow-up CT images showed resolution of these findings. Solid nodules developed at 18 of the 62 (29%) biopsy sites. Conclusion: Postbiopsy hemorrhage and pneumatoceles on intraprocedural CBCT images (which were clinically occult and resolved spontaneously) and new solid nodules on follow-up chest CT images were commonly observed after TBLC. These findings may help alleviate unnecessary follow-up imaging and tissue sampling.Keywords: Biopsy/Needle Aspiration, CT, Lungs, Lung Biopsy, Interventional Bronchoscopy© RSNA, 2023.

ABSTRACT

Malignant central airway obstruction (MCAO) is a debilitating and life-limiting complication that occurs in an unfortunately large number of individuals with advanced intrathoracic cancer. Although the management of MCAO is multimodal and interdisciplinary, the task of providing patients with prompt palliation falls increasingly on the shoulders of interventional pulmonologists. While a variety of tools and techniques are available for the management of malignant obstructive lesions, advancements and evolution in this therapeutic venue have been somewhat sluggish and limited when compared with other branches of interventional pulmonary medicine (e.g., the early diagnosis of peripheral lung nodules). Indeed, one pragmatic, albeit somewhat uncharitable, reading of this article's title might suggest a wry smile and shug of the shoulders as to imply that relatively little has changed in recent years. That said, the spectrum of interventions for MCAO continues to expand, even if at a less impressive clip. Herein, we present on MCAO and its endoscopic and nonendoscopic management-that which is old, that which is new, and that which is still on the horizon.

ABSTRACT

BACKGROUND: The Agency for Healthcare Research and Quality held a research meeting on using Consumer Assessment of Healthcare Providers and Systems (CAHPS®) data for quality improvement (QI) and evaluating such efforts. TOPICS COVERED.: Meeting addressed: 1)What has been learned about organizational factors/environment needed to improve patient experience? 2)How have organizations used data to improve patient experience? 3)What can evaluations using CAHPS data teach us about implementing successful programs to improve patient experience? KEY THEMES: Providers and stakeholders need to be engaged early and often, standardize QI processes, complement CAHPS data with other data, and compile dashboards of CAHPS scores to identify and track improvement. Rigorous study designs are valuable, but much can be learned and accomplished through practical organization-level studies.

ABSTRACT

OBJECTIVE: Adapting mental health-care interventions to the race, ethnicity, or culture of the target group can enhance the acceptance and effectiveness of the treatment. Dialectical behavior therapy (DBT) is an evidence-based treatment that is principle-driven, rendering it well-suited for adaptations across cultural contexts. This article conducts a systematic review of the literature to determine the nature and extent of cultural adaptations of DBT to date. METHOD: We searched databases for original articles describing cultural adaptations of DBT, as applied to both (a) people of color within Western countries and (b) populations within non-Western countries. Consistent with the focus on descriptively characterizing extant DBT cultural adaptations, we included both published and nonpublished studies, as well as both observational and experimental studies. RESULTS: Our search yielded 18 articles that met inclusion criteria. Of these articles, half described adaptations made with people and communities of color within the U.S. Most adaptations involved modifications to language, metaphors, methods, and context. CONCLUSIONS: Culturally adapted DBT has been implemented and accepted among several racial, ethnic, and cultural groups, although there is insufficient evidence to determine whether culturally adapted DBT is more efficacious than nonadapted DBT. We conclude with recommendations for best practices for DBT researchers and clinicians, and situate our findings among larger efforts to render existing evidence-based psychotherapies more optimal for people of color and people from non-Western countries.

ABSTRACT

BACKGROUND: Dialectical behavior therapy (DBT) is an effective approach to decreasing suicidal behaviors; the adapted, family-based model for adolescents (through 18 years old; DBT-A) also demonstrates efficacy. Data on higher dropout rates based on age, initial research on DBT with young adults in the community, and the theory that underlies DBT suggest that adaptations may also be appropriate for young adults. This study examines the effectiveness of DBT-A, presents preliminary data on delivering DBT-A to young adults (ages 18-26), and compares clinical characteristics, service utilization, and outcomes to adolescent clients (ages 13-17) to guide clinical considerations and future research on implementing DBT-A. METHODS: Data were collected from a DBT-A clinic and included results from semi-structured diagnostic interviews, chart review, and scores on self-report measures. The Suicide Ideation Questionnaire and Beck Depression Inventory (BDI), given at program entry, after completion of one rotation through the skills modules, and at graduation, were used to evaluate outcomes. Outcomes were benchmarked against prior DBT-A trials. Adolescents' and young adults' clinical characteristics, service utilization, and outcomes were compared. RESULTS: The effect size observed was smaller than in efficacy trials. Few differences were observed between teens (n = 87) and young adults (n = 45). Young adults were more likely to have participated in intensive services before DBT-A. They participated in fewer family sessions and graduated in fewer months compared to teens. CONCLUSION: This study supports the use of the family-based model of DBT for suicidal teens and young adults although future research is needed to improve the effectiveness of this model when implemented in real-world settings.

ABSTRACT

Several clinical calculators predict intensive care unit (ICU) mortality, however these are cumbersome and often require 24 h of data to calculate. Retrospective studies have demonstrated the utility of whole blood transcriptomic analysis in predicting mortality. In this study, we tested prospective validation of an 11-gene messenger RNA (mRNA) score in an ICU population. Whole blood mRNA from 70 subjects in the Stanford ICU Biobank with samples collected within 24 h of Emergency Department presentation were used to calculate an 11-gene mRNA score. We found that the 11-gene score was highly associated with 60-day mortality, with an area under the receiver operating characteristic curve of 0.68 in all patients, 0.77 in shock patients, and 0.98 in patients whose primary determinant of prognosis was acute illness. Subjects with the highest quartile of mRNA scores were more likely to die in hospital (40% vs 7%, p < 0.01) and within 60 days (40% vs 15%, p = 0.06). The 11-gene score improved prognostication with a categorical Net Reclassification Improvement index of 0.37 (p = 0.03) and an Integrated Discrimination Improvement index of 0.07 (p = 0.02) when combined with Simplified Acute Physiology Score 3 or Acute Physiology and Chronic Health Evaluation II score. The test performed poorly in the 95 independent samples collected > 24 h after emergency department presentation. Tests will target a 30-min turnaround time, allowing for rapid results early in admission. Moving forward, this test may provide valuable real-time prognostic information to improve triage decisions and allow for enrichment of clinical trials.

ABSTRACT

BACKGROUND: Systemic arterial gas embolism (SAGE) is a rare yet serious and underrecognized complication of bronchoscopic procedures. A recent case of presumed SAGE after transbronchial needle aspiration prompted a systematic literature review of SAGE after biopsy procedures during flexible bronchoscopy. METHODS: We performed a systematic database search for case reports and case series pertaining to SAGE after bronchoscopic lung biopsy; reports or series involving only bronchoscopic laser therapy or argon plasma coagulation (APC) were excluded. Patient data were extracted directly from published reports. RESULTS: A total of 29 unique patient reports were assessed for patient demographics, specifics of the procedure, clinical manifestations, diagnostic findings, and clinical outcomes. Cases of SAGE occurred after multiple types of bronchoscopic biopsy and under both positive and negative pressure ventilation. The most common clinical findings were neurologic, followed by cardiac manifestations; temporal patterns included acute onset of cardiac or neurologic emergencies immediately after biopsy, or delayed awakening post-procedure. There was a high mortality rate among cases (28%), with residual neurologic deficits also common (24%). DISCUSSION: SAGE is an underrecognized but severe adverse effect of bronchoscopic lung biopsy, which often presents with acute coronary or cerebral ischemia or delayed awakening from sedation. It is important for all physicians who perform bronchoscopic biopsies to be aware of the clinical manifestations and therapeutic management of SAGE in order to mitigate morbidity and mortality among patients undergoing these procedures.

ABSTRACT

Improved identification of bacterial and viral infections would reduce morbidity from sepsis, reduce antibiotic overuse, and lower healthcare costs. Here, we develop a generalizable host-gene-expression-based classifier for acute bacterial and viral infections. We use training data (N = 1069) from 18 retrospective transcriptomic studies. Using only 29 preselected host mRNAs, we train a neural-network classifier with a bacterial-vs-other area under the receiver-operating characteristic curve (AUROC) 0.92 (95% CI 0.90-0.93) and a viral-vs-other AUROC 0.92 (95% CI 0.90-0.93). We then apply this classifier, inflammatix-bacterial-viral-noninfected-version 1 (IMX-BVN-1), without retraining, to an independent cohort (N = 163). In this cohort, IMX-BVN-1 AUROCs are: bacterial-vs.-other 0.86 (95% CI 0.77-0.93), and viral-vs.-other 0.85 (95% CI 0.76-0.93). In patients enrolled within 36 h of hospital admission (N = 70), IMX-BVN-1 AUROCs are: bacterial-vs.-other 0.92 (95% CI 0.83-0.99), and viral-vs.-other 0.91 (95% CI 0.82-0.98). With further study, IMX-BVN-1 could provide a tool for assessing patients with suspected infection and sepsis at hospital admission.

ABSTRACT

INTRODUCTION: Lung nodules are being identified with increasing frequency. With this growing burden of nodules comes a growing need for diagnostic technologies extending beyond the current reach of conventional bronchoscopy. One such method for diagnosing peripheral lung lesions is electromagnetic navigational bronchoscopy (ENB), which comprises a set of tools designed to aid the bronchoscopist in identifying, accessing, and sampling peripheral lung lesions under virtual guidance. AREAS COVERED: Herein we present an in-depth review of ENB, including commercially available electromagnetic navigation platforms, factors influencing diagnostic yield, adjunctive imaging and biopsy tools, potential risks, cost, technical shortcomings, and competing technologies. A review of the scientific literature was conducted primarily through PubMed, ScienceDirect, and Google Scholar, and pertinent publications and abstracts from the inception of electromagnetic navigation through early 2020 were considered. We also share our perspective on the future of ENB from both a diagnostic and a therapeutic standpoint. EXPERT OPINION: ENB is currently a leading tool in the diagnostic evaluation of peripheral lung lesions. The future of ENB rests not only on its potential to expand into the therapeutic realm but also on its ability to keep pace with competing diagnostic and therapeutic technologies.

ABSTRACT

Patient narratives have emerged as promising vehicles for making health care more responsive by helping clinicians to better understand their patients' expectations, perceptions, or concerns and encouraging consumers to engage with information about quality. A growing number of websites incorporate patients' comments. But existing comments have fragmentary content, fail to represent less vocal patients, and can be manipulated to "manage" providers' reputations. In this article, we offer the first empirical test of the proposition that patient narratives can be elicited rigorously and reliably using a five-question protocol that can be incorporated into large-scale patient experience surveys. We tested whether elicited narratives about outpatient care are complete (report all facets of patient experience), balanced (convey an accurate mix of positive and negative events), meaningful (have a coherent storyline), and representative (draw fulsome narratives from all relevant subsets of patients). The tested protocol is strong on balance and representativeness, more mixed on completeness and meaningfulness.
