Bronchoscopy Teaching Without a Gold Standard: Attending Pulmonologists' Assessment of Learners, Supervisory Styles, and Variation in Practice.

BACKGROUND: Despite the growing role of simulation in procedural teaching, bronchoscopy training largely is experiential and occurs during patient care. The Accreditation Council for Graduate Medical Education sets a target of 100 bronchoscopies to be performed during pulmonary fellowship. Attending physicians must balance fellow autonomy with patient safety during these clinical teaching experiences. Few data on best practices for bronchoscopy teaching exist, and a better understanding of how bronchoscopy currently is supervised could allow for improvement in bronchoscopy teaching. RESEARCH QUESTION: How do attending bronchoscopists supervise bronchoscopy, and in particular, how do attendings balance fellow autonomy with patient safety? STUDY DESIGN AND METHODS: This was a focused ethnography conducted at a single center using audio recording of dialog between attendings and fellows during bronchoscopies, supplemented by observation of nonverbal teaching. Interviews with attending bronchoscopists and limited interviews of fellows also were recorded. Interviews were transcribed verbatim before analysis. We used constant comparative analysis to analyze data and qualitative research software to support data organization and thematic analysis. Education researchers from outside of pulmonary critical care joined the team to minimize bias. RESULTS: We observed seven attending bronchoscopists supervising eight bronchoscopies. We noted distinct teaching behaviors, classified into themes, which then were grouped into four supervisory styles of modelling, coaching, scaffolding, and fading. Observation and interviews illuminated that assessing fellow skill was one tool used to choose a style, and attendings moved between styles. Attendings accepted some, but not all, variation in both performing and supervising bronchoscopy. INTERPRETATION: Attending pulmonologists used a range of teaching microskills as they moved between different supervisory styles and selectively accepted variation in practice. These distinct approaches may create well-rounded bronchoscopists by the end of fellowship training and should be studied further.

Quality of spirometry and related diagnosis in primary care with a focus on clinical use.

American and European societies' (ATS/ERS) criteria for spirometry are often not met in primary care. Yet, it is unknown if quality is sufficient for daily clinical use. We evaluated quality of spirometry in primary care based on clinical usefulness, meeting ATS/ERS criteria and agreement on diagnosis between general practitioners (GPs) and pulmonologists. GPs included ten consecutive spirometry tests and detailed history questionnaires of patients who underwent spirometry as part of usual care. GPs and two pulmonologists assessed the spirometry tests and questionnaires on clinical usefulness and formulated a diagnosis. In total, 149 participants covering 15 GPs were included. Low agreements were found on diagnosis between GPs and pulmonologists 1 (κ = 0.39) and 2 (κ = 0.44). GPs and pulmonologists rated >88% of the tests as clinically useful, although 13% met ATS/ERS criteria. This real-life study demonstrated that clinical usefulness of routine primary care spirometry tests was high, although agreement on diagnosis was low.

Bronchoscopic Diagnostic Procedures Available to the Pulmonologist.

In the diagnosis of lung cancer, pulmonologists have several tools at their disposal. From the tried and true convex probe endobronchial ultrasound (EBUS)-guided transbronchial needle aspiration to robotic bronchoscopy for peripheral lesions and new technology to unblind the biopsy tools, this article elucidates and expounds on the tools currently available and being developed for lung cancer diagnosis.

Therapeutic Bronchoscopic Techniques Available to the Pulmonologist: Emerging Therapies in the Treatment of Peripheral Lung Lesions and Endobronchial Tumors.

Therapeutic bronchoscopy for both endobronchial tumors and peripheral lung cancer is rapidly evolving. The expected increase in early stage lung cancer detection and significant improvement in near real-time imaging for diagnostic bronchoscopy has led to the development of bronchoscopy-delivered ablative technologies. Therapies targeting obstructing central airway tumors for palliation and as a method of local disease control, patient selection and patient-centered outcomes have been areas of ongoing research. This review focuses on patient selection when considering therapeutic bronchoscopy and new and developing technologies for endobronchial tumors and reviews the status of bronchoscopy-delivered ablative tools for peripheral lung cancers.

Identifying causation in hypersensitivity pneumonitis: a British perspective.

Background: Establishing whether patients are exposed to a 'known cause' is a key element in both the diagnostic assessment and the subsequent management of hypersensitivity pneumonitis (HP). Objective: This study surveyed British interstitial lung disease (ILD) specialists to document current practice and opinion in relation to establishing causation in HP. Methods: British ILD consultants (pulmonologists) were invited by email to take part in a structured questionnaire survey, to provide estimates of demographic data relating to their service and to rate their level of agreement with a series of statements. A priori 'consensus agreement' was defined as at least 70% of participants replying that they 'Strongly agree' or 'Tend to agree'. Results: 54 consultants took part in the survey from 27 ILD multidisciplinary teams. Participants estimated that 20% of the patients in their ILD service have HP, and of these, a cause is identifiable in 32% of cases. For patients with confirmed HP, an estimated 40% have had a bronchoalveolar lavage for differential cell counts, and 10% a surgical biopsy. Consensus agreement was reached for 25 of 33 statements relating to causation and either the assessment of unexplained ILD or management of confirmed HP. Conclusions: This survey has demonstrated that although there is a degree of variation in the diagnostic approach for patients with suspected HP in Britain, there is consensus opinion for some key areas of practice. There are several factors in clinical practice that currently act as potential barriers to identifying the cause for British HP patients.

[Smoking cessation: A challenge for cardiologists and pulmonologists]. / Sevrage tabagique : un défi pour les cardiologues et les pneumologues.

In addition to public health measures that need to be strongly supported politically, smoking is also a major medical issue. Tobacco dependence is a chronic disease, and, given its extremely addictive nature, treatment for tobacco dependence must be addressed actively by all health professionals. Because smoking is a major contributor to many of the pathologies their specialties address, cardiologists and pulmonologists must be at the forefront of this care. In this review we analyse the current state of smoking cessation treatment and its inadequacies, the limiting impact that doctors' own smoking has, as well as the misconceptions held by smokers and sometimes by doctors as well, which act as brakes on smoking cessation. Smoking cessation must become a treatment delivered in real clinical practice and any doctor must know how to manage it fluently. Do not be satisfied with simply advising smokers to quit. Learn how to approach the subject with smokers effectively, know how the various pharmacotherapies are used and know how to organize smoking cessation follow-up, an essential guarantee of success. If optimal management of this major pathological factor is a role for all doctors, it is of course especially so for our two specialties. It's up to us, cardiologists and pulmonologists, to take up this challenge.

Atypical manifestations of granulomatosis with polyangiitis: the diagnostic challenge for pulmonologists.

This is a review considering atypical manifestations of granulomatosis with polyangiitis (GPA). Virtually any organ can be affected, and in some patients, GPA can manifest unusually. Since thoracic involvement of GPA often predominates, the first who might be expected to establish a diagnosis are pulmonary specialists. We would like to familiarize pulmonary specialists with several extra-ELK (E: ear-nose-throat; L: lung; K: kidney) involvements of the disease. We describe sites rarely affected by GPA like the breast, skeletal system, orbit and eye, heart and vessels, central nervous system, urogenital system as well as endocrine and gastrointestinal tract involvement.

Pulmonologist's Road Map to Mediastinal Lymph Node Imaging.

Mediastinal lymph node station maps are intended to facilitate nodal staging in patients with non-small cell lung cancer. These maps have been revised over time and the International Association for Study of Lung Cancer (IASLC) map is the latest rendition. This article illustrates the imaging appearance of each of the IASLC map mediastinal lymph node stations, overviews some of the mediastinal lymph node sampling techniques, and discusses common pitfalls of the IASLC map. It also reviews mediastinal anatomic variants and pathologic features that may simulate lymphadenopathy.

Diagnostic accuracy of a clinical diagnosis of idiopathic pulmonary fibrosis: an international case-cohort study.

We conducted an international study of idiopathic pulmonary fibrosis (IPF) diagnosis among a large group of physicians and compared their diagnostic performance to a panel of IPF experts.A total of 1141 respiratory physicians and 34 IPF experts participated. Participants evaluated 60 cases of interstitial lung disease (ILD) without interdisciplinary consultation. Diagnostic agreement was measured using the weighted kappa coefficient (κw). Prognostic discrimination between IPF and other ILDs was used to validate diagnostic accuracy for first-choice diagnoses of IPF and were compared using the C-index.A total of 404 physicians completed the study. Agreement for IPF diagnosis was higher among expert physicians (κw=0.65, IQR 0.53-0.72, p<0.0001) than academic physicians (κw=0.56, IQR 0.45-0.65, p<0.0001) or physicians with access to multidisciplinary team (MDT) meetings (κw=0.54, IQR 0.45-0.64, p<0.0001). The prognostic accuracy of academic physicians with >20 years of experience (C-index=0.72, IQR 0.0-0.73, p=0.229) and non-university hospital physicians with more than 20 years of experience, attending weekly MDT meetings (C-index=0.72, IQR 0.70-0.72, p=0.052), did not differ significantly (p=0.229 and p=0.052 respectively) from the expert panel (C-index=0.74 IQR 0.72-0.75).Experienced respiratory physicians at university-based institutions diagnose IPF with similar prognostic accuracy to IPF experts. Regular MDT meeting attendance improves the prognostic accuracy of experienced non-university practitioners to levels achieved by IPF experts.

Clinical audit of COPD in outpatient respiratory clinics in Spain: the EPOCONSUL study.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) outpatients account for a large burden of usual care by respirologists. EPOCONSUL is the first national clinical audit conducted in Spain on the medical care for COPD patients delivered in outpatient respiratory clinics. We aimed to evaluate the clinical interventions and the degree of adherence to recommendations in outpatients of current COPD clinical practice guidelines. METHODOLOGY: This is an observational study with prospective recruitment (May 2014-May 2015) of patients with a COPD diagnosis as seen in outpatient respiratory clinics. The information collected was historical in nature as for the clinical data of the last and previous consultations, and the information concerning hospital resources was concurrent. RESULTS: A total of 17,893 clinical records of COPD patients in outpatient respiratory clinics from 59 Spanish hospitals were evaluated. Of the 5,726 patients selected, 4,508 (78.7%) were eligible. Overall, 12.1% of COPD patients did not fulfill a diagnostic spirometry criteria. Considerable variability existed in the available resources and work organization of the hospitals, although the majority were university hospitals with respiratory inpatient units. There was insufficient implementation of clinical guidelines in preventive and educational matters. In contrast, quantitative evaluation of dyspnea grade (81.9%) and exacerbation history (70.9%) were more frequently performed. Only 12.4% had COPD severity calculated according to the Body mass index, airflow Obstruction, Dyspnoea and Exercise capacity (BODE) index. Phenotype characteristics according to Spanish National Guideline for COPD were determined in 46.3% of the audited patients, and the risk evaluation according to Global initiative for chronic Obstructive Lung Disease was estimated only in 21.9%. CONCLUSION: The EPOCONSUL study reports the current situation of medical care for COPD patients in outpatient clinics in Spain, revealing its variability, strengths, and weaknesses. This information has to be accounted for by health managers to define corrective strategies and maximize good clinical practice.

Physician Assessment of Pretest Probability of Malignancy and Adherence With Guidelines for Pulmonary Nodule Evaluation.

BACKGROUND: The annual incidence of pulmonary nodules is estimated at 1.57 million. Guidelines recommend using an initial assessment of nodule probability of malignancy (pCA). A previous study found that despite this recommendation, physicians did not follow guidelines. METHODS: Physician assessments (N = 337) and two previously validated risk model assessments of pretest probability of cancer were evaluated for performance in 337 patients with pulmonary nodules based on final diagnosis and compared. Physician-assessed pCA was categorized into low, intermediate, and high risk, and the next test ordered was evaluated. RESULTS: The prevalence of malignancy was 47% (n = 158) at 1 year. Physician-assessed pCA performed better than nodule prediction calculators (area under the curve, 0.85 vs 0.75; P < .001 and .78; P = .0001). Physicians did not follow indicated guidelines when selecting the next test in 61% of cases (n = 205). Despite recommendations for serial CT imaging in those with low pCA, 52% (n = 13) were managed more aggressively with PET imaging or biopsy; 12% (n = 3) underwent biopsy procedures for benign disease. Alternatively, in the high-risk category, the majority (n = 103 [75%]) were managed more conservatively. Stratified by diagnosis, 92% (n = 22) with benign disease underwent more conservative management with CT imaging (20%), PET scanning (15%), or biopsy (8%), although three had surgery (8%). CONCLUSIONS: Physician assessment as a means for predicting malignancy in pulmonary nodules is more accurate than previously validated nodule prediction calculators. Despite the accuracy of clinical intuition, physicians did not follow guideline-based recommendations when selecting the next diagnostic test. To provide optimal patient care, focus in the areas of guideline refinement, implementation, and dissemination is needed.

Variability in anesthesiologists' approach to the preoperative management of asthmatic children.

OBJECTIVE: No consensus guidelines exist for the preoperative treatment of asthmatic children referred for elective surgery. We investigated the attitude of pediatric anesthesiologists to this issue. DESIGN: A questionnaire survey was conducted. SETTING: National survey. SUBJECTS: Certified Israeli pediatric anesthesiologists from all 24 general hospitals in Israel. MEASUREMENT: Twenty-one questions regarding the approach to preoperative management of asthmatic children including 6 case scenarios with a variety of clinical situations and treatments of asthmatic children. The results were compared with the attitude of pediatric pulmonologists recently published using a similar methodology. MAIN RESULTS: Forty-four pediatric anesthesiologists from all 24 general hospitals in Israel responded. Twenty-five percent of pediatric anesthesiologists answered that, in addition to pediatric anesthesiologists, the primary pediatrician should be consulted, and 70% believed that a pediatric pulmonologists should also be consulted. Overall, results showed a wide variability between responders especially for preschool children and unstable school-aged asthmatic children for both disciplines. The variability referred to the use of any treatment, bronchodilators, inhaled corticosteroids and their combination, addition of systemic corticosteroids, and the length of preoperative treatment. Compared with pediatric pulmonologists, a better within-discipline agreement was observed by the pediatric anesthesiologists for stable school-aged asthmatic children with a lower inclination to augment preoperative treatment (P< .001). No difference was observed for the preschool children with asthma and for the unstable school-aged asthmatic child. CONCLUSIONS: A wide variability exists in pediatric anesthesiologists' approach to the preoperative management of asthmatic children for most common case scenarios. This is probably explained by the heterogeneity of asthma, the type of surgery, the lack of guidelines, and the paucity of data. Similarities as well as differences exist between pediatric anesthesiologists and pulmonologists. Further studies and implementation of consensus guidelines are needed.
