Association of patient-reported outcome measures with lung function and mortality in fibrotic interstitial lung disease: a prospective cohort study.

Background: Patient-reported outcome measures (PROMs) may provide clinicians and researchers with direct insights into disease impact and patient well-being. We assessed whether selected PROMs and their domains are associated with baseline and longitudinal changes in lung function and can predict mortality in patients with fibrotic interstitial lung disease (f-ILD). Methods: A single-centre prospective study of adult patients with f-ILD enrolled over 3 years was conducted assessing baseline and short-term changes in PROMs. Three questionnaires, the modified Medical Research Council dyspnoea scale (mMRC), Chronic Respiratory Questionnaire (CRQ) and Self-Management Ability Scale (SMAS-30) were administered at planned intervals and assessed for their association with baseline clinical findings, change in lung function (% predicted forced vital capacity (FVC%) and diffusion capacity of the lung for carbon monoxide (DLCO%)) and all-cause mortality. Results: 199 patients were enrolled with a mean PROM follow-up of 9.6 months. When stratified by FVC% quartiles at presentation, lower mMRC (less dyspnoea), higher CRQ Physical and Emotional domain (better health-related quality of life) and higher total SMAS-30 scores (better self-management ability) were associated with higher FVC%. Short-term changes in all three PROMs appeared to be associated with changes in FVC% and DLCO%. Adjusted and unadjusted baseline and serial PROM changes were also predictive of mortality. Conclusions: Baseline and serial assessments of PROMs were associated with changes in lung function and predicted death in patients with f-ILD. PROMs may strengthen comprehensive assessments of disease impact in clinical practice as well as support patient-centred outcomes in research.

Leveraging multisource feedback to address diversity, equity, and inclusivity.

Multisource feedback has long been a recommended tool to assess clinical competencies within graduate medical education. Additionally, incorporating feedback supplied by patients and other members of the healthcare team can provide the framework to bridge perspectives and viewpoints that may be different from their own. This, in effect, can aid in fortifying values in diversity, equity, and inclusivity by developing more knowledgeable, empathetic, and respectful future healthcare providers.

Decision-Making for Hospitalized Incarcerated Patients Lacking Decisional Capacity.

Importance: Incarcerated patients admitted to the hospital face threats to their rights to privacy and self-determination in medical decision-making. Little is known about medical decision-making processes for hospitalized incarcerated persons who lack decisional capacity. Objective: To characterize the prevalence of incapacity among hospitalized incarcerated patients and describe the decision-making processes, including who served as surrogate decision-makers, involvement of prison employees in medical decisions, and ethical concerns emerging from the patients' care. Design, Setting, and Participants: Retrospective descriptive and qualitative study of medical records for all patients admitted from prison for at least 24 hours between January 1, 1999, and September 1, 2019, at a large Midwestern academic medical center. Data analysis was performed from March 15, 2021, to December 14, 2022. Main Outcomes and Measures: Prevalence of prison-to-hospital admissions for patients with a loss of capacity and characteristics of medical decision-making. Results: During the 20-year study period, 462 patients from the prison were admitted to the hospital, totaling 967 unique admissions. Of these, 131 admissions (14%) involved patients with a loss of capacity and 43 admissions (4%, representing 34 unique patients) required surrogate decision-making. Ten of these patients had advance directives. Surrogate decision-makers often faced decisions about end-of-life care (n = 17) or procedural consent (n = 23). A family member was identified as surrogate decision-maker in 23 admissions. In 6 cases with a kindred surrogate, additional consent was requested from a prison employee. In total, prison employees were documented as being present during or participating in major medical decisions for half of the admissions. Five themes emerged from thematic analysis: uncertainty and misinformation about patient rights and the role of prison employees in medical decision-making with respect to these two themes, privacy violations, deference to prison officials, and estrangement from family and friends outside of the prison. Conclusions and Relevance: In this first in-depth description, to date, of decision-making practices for hospitalized incarcerated patients lacking decisional capacity, admissions of these patients generated uncertainty about their rights, sometimes infringing on patients' privacy and autonomy. Clinicians will encounter incarcerated patients in both hospital and clinic settings and should receive education on how to support ethically and legally sound decision-making practices for this medically vulnerable population.

Evaluation of automated sample preparation system for lymph node sampling.

Background: Endobronchial ultrasound-guided transbronchial fine needle aspiration (EBUS-FNA) has revolutionized the diagnostic and staging approach to non-small cell carcinoma and thoracic lymphadenopathy. However, obstacles to efficacy of rapid on-site evaluation (ROSE) of the samples include variability in sample quality and slow and cumbersome process in the procedure room leading to extended procedure time. The purpose of this pilot study was to evaluate the feasibility and specimen quality of lymph node biopsies prepared through a novel automated system for automated fixation, drying and staining compared to standard slide preparation method. Methods: We performed a prospective, single-center pilot feasibility study of patients undergoing EBUS. Samples were split into conventional standard of care (SOC) slide preparation and preparation using the device ("instrument"). Pathologists compared the SOC slides to the slides prepared by the automated system and assessed the following metrics: nuclear and cytoplasmic quality, presence of debris/artifact, staining quality, creation of a monolayer, and ease of adequacy/diagnosis assessment. A score between 1 (lowest quality) and 3 (highest quality) was assigned to the above metrics. Results: Sixty patients were recruited. One to three lymph nodes were sampled for each patient for a total of 72 samples collected. The mean scores of each assessment category showed no statistical difference between the two preparation techniques except for improved monolayer creation in the instrument samples. Thirty of thirty-one (96.8%) paired samples in the final analysis showed diagnostic equivalency between the automated slides and conventional slides; the discordant pairing was reported to be suspicious on the instrument sample and atypical on the SOC. Conclusions: Study results suggest that slides prepared by the automated system are of adequate quality for adequacy assessment with diagnostic concordance when compared to SOC slides.

Robotic bronchoscopy: potential in diagnosing and treating lung cancer.

INTRODUCTION: Lung cancer remains the deadliest form of cancer in the world. Screening through low-dose CT scans has shown improved detection of pulmonary nodules; however, with the introduction of robotic bronchoscopy, accessing and biopsying peripheral pulmonary nodules from the airway has expanded. Improved diagnostic yield through enhanced navigation has made robotic bronchoscopy an ideal diagnostic technology for many proceduralists. Studies have demonstrated that robotic bronchoscopes can reach further with improved maneuverability into the distal airways compared to conventional bronchoscopes. AREAS COVERED: This review paper highlights the literature on the technological advancements associated with robotic bronchoscopy and the future directions the field of interventional pulmonary may utilize this modality for in the treatment of lung cancer. Referenced articles were included at the discretion of the authors after a database search of the particular technology discussed. EXPERT OPINION: As the localization of target lesions continues to improve, robotic platforms that provide reach, stability, and accuracy paves the way for future research in endoluminal treatment for lung cancer. Future studies with intratumoral injection of chemotherapy and immunotherapy and ablation modalities are likely to come in the coming years.

Home-Based Pulmonary Rehabilitation and Health Coaching in Fibrotic Interstitial Lung Disease: IMPLEMENTATION AND QUALITATIVE ASSESSMENT OF A PILOT TELEHEALTH PROGRAM.

PURPOSE: Pulmonary rehabilitation is a behavioral modification intervention shown to improve exercise tolerance and patient-reported quality of life in patients with fibrotic interstitial lung disease. Home-based rehabilitation may provide easier access for those who struggle to complete center-based rehabilitation programs due to increased symptom burden or frailty. METHODS: We present the quantitative and qualitative findings of a pilot study of 21 patients with fibrotic interstitial lung disease who participated in a 12-wk home-based pulmonary rehabilitation program with activity monitoring and health coaching. RESULTS: Pre- and post-intervention patient-reported outcome questionnaires suggested improvements in dyspnea and respiratory-related quality of life but were underpowered to meet statistical significance. Half had increases in mean daily step counts while a quarter declined because of disease progression. Qualitative analysis of semistructured participant interviews suggested a significant baseline disease burden with related secondary impacts, including anxiety regarding disease progression and prognosis. Many who participated had no specific program expectations or self-determined goals but still found the program impactful, particularly on their abilities to adapt and cope with the disease. CONCLUSION: Our study suggests feasibility in a diverse set of patients with varying severity and diagnostic subtypes. We also provide quantitative and qualitative aspects of program impact on patient well-being and highlight the complex interaction between measured physical and self-reported outcomes and disease experience.

Enhancing Nodule Biopsy Through Technology Integration.

Technology in navigating to peripheral pulmonary nodules has improved in recent years. The recent integration of a robotic platform using shape-sensing technology and mobile cone-beam computed tomography imaging technology has enhanced confidence in sampling lesions with intraprocedural imaging by complimenting the pre-planned navigation to peripheral pulmonary nodules. We present 2 cases using the software integration that improved the robotic catheter positioning to allow for diagnostic specimens to be obtained in the initial biopsies.

Combined portable cone beam computed tomography and robotic-assisted bronchoscopy impacting diagnosis of a solitary pulmonary nodule: a case report.

Background: Lung cancer is the leading cause of cancer-related mortality in men and women throughout the world. Historically, bronchoscopy played a limited role in pulmonary nodule management due to a limited diagnostic accuracy. With the emergence of robotic bronchoscopy, proceduralists can now navigate to more peripheral lesions completely extrinsic to the airways with increased diagnostic yield. Despite the increased diagnostic yield from robotic-assisted bronchoscopy, challenges in exact localization of the lesion during a procedure can occur. This case highlights a novel use of robotic bronchoscopy combined with mobile three-dimensional (3D) imaging to optimize lesion location for biopsy previously not reported in the literature. Case Description: We describe a case where the combination of robotic bronchoscopy with new mobile 3D imaging was essential for the accurate biopsy of an incidentally found pulmonary nodule in a 72-year-old woman. Initial navigation to the nodule using robotic bronchoscopy resulted in the catheter being inferior to the area of interest. After renavigation using the information provided by mobile 3D imaging, we were able to confirmed tool-in-lesion prior to biopsy. The patient was diagnosed with adenocarcinoma with papillary features and underwent a lobectomy with a favorable prognosis. Conclusions: A diagnosis of adenocarcinoma was made for this patient utilizing the novel combined technique of robotic peripheral pulmonary nodule biopsy with portable 3D imaging, which may improve overall diagnostic accuracy of bronchoscopic biopsy.

Combining Shape-Sensing Robotic Bronchoscopy With Mobile Three-Dimensional Imaging to Verify Tool-in-Lesion and Overcome Divergence: A Pilot Study.

Objective: To determine whether CT-to-body divergence can be overcome to improve the diagnostic yield of peripheral pulmonary nodules with the combination of shape-sensing robotic-assisted bronchoscopy (SSRAB) and portable 3-dimensional (3D) imaging. Patients and Methods: A single-center, prospective, pilot study was conducted from February 9, 2021, to August 4, 2021, to evaluate the combined use of SSRAB and portable 3D imaging to visualize tool-in-lesion as a correlate to diagnostic yield. Results: Thirty lesions were subjected to biopsy in 17 men (56.7%) and 13 women (43.3%). The median lesion size was 17.5 mm (range, 10-30 mm), with the median airway generation of 7 and the median distance from pleura of 14.9 mm. Most lesions were in the upper lobes (18, 60.0%). Tool-in-lesion was visualized at the time of the procedure in 29 lesions (96.7%). On the basis of histopathologic review, 22 (73.3%) nodules were malignant and 6 (20.0%) were benign. Two (6.7%) specimens were suggestive of inflammation, and the patients elected observation. The mean number of spins was 2.5 (±1.6) with a mean fluoroscopy time of 8.7 min and a mean dose area product of 50.3 Gy cm2 (±32.0 Gy cm2). There were no episodes of bleeding or pneumothorax. The diagnostic yield was 93.3%. Conclusion: This pilot study shows that the combination of mobile 3D imaging and SSRAB of pulmonary nodules appears to be safe and feasible. In conjunction with appropriate anesthetic pathways, nodule motion and divergence can be overcome in most patients. Trial Registration: https://clinicaltrials.gov Identifier NCT04740047.
