OBJECTIVES The objectives of this study were to describe treatments, exacerbation outcomes and healthcare resource utilization (HCRU) for patients with controlled and uncontrolled SA in Alberta, Canada. METHODS A retrospective cohort of SA patients 12+ years (April 1, 2011 to March 31, 2020) was identified from administrative health data, based on medication dispensed for controlling asthma symptoms, stratified by disease control at index. Treatment patterns were analyzed for incident SA patients. Annualized exacerbation incidence rate ratios (IRR) were estimated throughout follow-up and stratified by disease control at index. Asthma-specific HCRU and direct costs were calculated. RESULTS The study cohort included 74,134 patients (12.4% of eligible asthma patients) of whom 71,099 (95.5%) were classified as controlled and 3,035 (4.1%) as uncontrolled at index. Inhaled corticosteroid + long-acting beta agonist (ICS + LABA) was the most frequent first-line therapy among incident SA patients (n = 53,084), received by 42.7% of patients. A minority received >2 lines of therapy; few received triple therapy. The uncontrolled (at index) versus controlled (at index) cohort had a 5.5 times higher exacerbation rate (IRR: 5.5, 95% CI: 5.1–5.8; p < 0.001), higher HCRU, and higher associated annual costs (mean [SD]: $3,799 [$6,668] uncontrolled vs $1,339 [$2,515] controlled). CONCLUSIONS SA, whether controlled or uncontrolled at index, was associated with ongoing exacerbations and HCRU despite treatment intensification that identified patients as having SA. Some treatment patterns appeared misaligned with guidelines, suggesting potential need for better recognition of asthma severity and escalating therapies.","PeriodicalId":9471,"journal":{"name":"Canadian Journal of Respiratory, Critical Care, and Sleep Medicine","volume":"4 1","pages":"192 - 200"},"PeriodicalIF":0.8,"publicationDate":"2023-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91148503","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Major scientific advances in the last decade have dramatically changed the way we detect and treat lung cancers. British Columbia, Ontario and Quebec have recently launched lung cancer screening programs for high-risk individuals using evidence-based risk prediction models, and many other provinces are in the active planning phase. This review focuses on non-small cell lung cancer (NSCLC), which comprises 80-85% of lung cancers. For patients diagnosed with advanced or metastatic NSCLC, we now have systemic therapy options—targeted therapies, chemotherapies and immune checkpoint inhibitors (ICIs)—that are tailored to the molecular characterization of individual tumor samples for DNA/RNA alterations and PD-L1 protein expression. Molecular characterization is also becoming increasingly crucial for patients diagnosed with earlier and potentially curable NSCLC, as targeted therapies and ICIs make their way into the adjuvant and neoadjuvant therapy space, partnering with radiation and surgery to improve outcomes for patients receiving multimodality curative-intent treatment.","PeriodicalId":9471,"journal":{"name":"Canadian Journal of Respiratory, Critical Care, and Sleep Medicine","volume":"72 1","pages":"201 - 205"},"PeriodicalIF":0.8,"publicationDate":"2023-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74824881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sublingual fentanyl citrate (SLF) has a fast onset of action and a short half-life, both interesting characteristics to treat acute breakthrough dyspnea without inducing metabolite accumulation. The Montreal Chest Institute (MCI) COPD specialty clinic has been using low-dose SLF for patients with advanced COPD experiencing significant episodic dyspnea despite high intensity inhaled therapy. We present here a retrospective chart review, the largest to date, to report on a “real life” experience. METHODS All included patients had a formal diagnosis of COPD and were seen in the MCI COPD specialty clinic between January 1, 2015 and January 1, 2021. All patients prescribed SLF, irrespective of the duration of use, were enrolled in this chart review. Extent of symptom relief, categorized into either major, intermediate or no improvements, and adverse effects were inferred from in-person or telephone follow-up appointment clinical notes. An exacerbation was defined as a self-reported acute increase in symptoms leading to oral corticosteroid use or hospitalization. Rates of exacerbation and hospitalization in the 12 months before SLF initiation and during SLF use were compared. RESULTS In total, 17 COPD patients were given SLF during the study period. The mean FEV1 was 0.51 L (21% predicted). All participants reported MRC5/5 dyspnea and were prescribed regular low-dose oral morphine for daily breathlessness prior to SLF initiation. Most patients used SLF for more than 6 months, and 76.5% of the study group found intermediate or major improvement in breathlessness episodes. There was no significant change in the rates of exacerbation and admission for acute respiratory failure while on SLF. CONCLUSION In this review, we report real-life, long-term data on severe COPD patients using self-controlled as-needed SLF, showing patient acceptability, an improvement in dyspnea, and limited side effects. Hence, this represents an important step toward the first effective alternative rescue medication for the relief of breakthrough dyspnea since short-acting inhalers. Further study using a randomized trial design is required to confirm the efficacy of this therapy.","PeriodicalId":9471,"journal":{"name":"Canadian Journal of Respiratory, Critical Care, and Sleep Medicine","volume":"105 1","pages":"144 - 147"},"PeriodicalIF":0.8,"publicationDate":"2023-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80596567","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

OBJECTIVES A qualitative study was undertaken to explore the impacts of COVID-19 within this context. METHODS Patients who were being assessed or waiting for a lung transplant (n = 22) and their caregivers (n = 3) participated in semi-structured interviews conducted by phone. Interviews were transcribed and imported into NVivo 12 Pro software for the exploration and coding of data to arrive at themes. MAIN RESULTS: The majority of patients (n = 16) described limitations in their access to healthcare, including difficulty seeing their physician, delayed appointments and decreased in-person visits. Physical activity was greatly impacted (n = 15) “diminished,” “restricted” or “limited” or impacted “dramatically” due to COVID-19. Significant limitations were imposed on physical activities (n = 15) and social activities (n = 18), and financial concerns (n = 11) were common amongst this population. For many, these impacts contributed to mental health struggles including increased stress, anxiety and depression. Patients coped using a variety of strategies, including partaking in hobbies, meditation and spirituality, mindset and self-talk, and expressed gratitude for their current situation and hope for the future. CONCLUSION Patients being assessed or listed for lung transplant have been affected by the global pandemic driven by an illness that is respiratory in nature. Patients who continue to struggle should be identified and appropriate supports should be provided. In the event of a future pandemic, the vulnerabilities in this population should be considered.","PeriodicalId":9471,"journal":{"name":"Canadian Journal of Respiratory, Critical Care, and Sleep Medicine","volume":"31 1","pages":"148 - 157"},"PeriodicalIF":0.8,"publicationDate":"2023-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82851530","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

OBJECTIVES The aim of this review was to describe: 1) the role and impact of RTs; 2) the recommendations for RT inclusion; and 3) regional differences in RT practices in adult critical care across Canada. METHODS AND MEASUREMENT A scoping review was performed. Eligible studies described the Canadian RT role in adult critical care. Data extraction was informed by the Respiratory Therapy Practice-Based Outcome Initiative Model (RT-PBOI), a conceptual model that outlines 5 domains of how RTs can contribute to patient care and resource utilization. MAIN RESULTS RTs’ roles across 22 studies were categorized into domains of the RT-PBOI model: Technical skills (n = 20), Approach to practice (n = 20), Leveraging capacity (n = 15), Strategic expertise (n = 16) and Growing value for the future (n = 17). The grey literature (n = 26) provided brief descriptions of the RT role across multiple practice settings, but common RT tasks in critical care were mechanical ventilation management and participation in specialized care teams. One grey literature report recommended RTs to participate as critical response team members and two studies briefly mentioned regional differences in RT roles. CONCLUSION There were minimal studies to report on the impact of RTs in Canadian, adult critical care. Future studies are needed to evaluate the RT role and their value in improving patient care and resource utilization.

ILAs have been identified on chest computed tomography (CT) performed as part of lung cancer screening programs. OBJECTIVES This study characterizes the prevalence and outcomes associated with ILA in a Canadian lung cancer screening cohort. METHODS Patients were identified from the Alberta lung cancer screening trial, a 5-year cohort study. CT reports were screened for terms associated with ILA including specific radiologic features and CT patterns. These were further characterized as non-subpleural, subpleural nonfibrotic and subpleural fibrotic, consistent with published definitions. Retrospective chart review was conducted for those with ILA to define demographics, lung function, and longitudinal outcomes including subsequent investigations for interstitial lung disease (ILD), treatment, and survival. MEASUREMENTS AND MAIN RESULTS Of 806 patients in the lung cancer screening study, 30 (3.7%) were identified as having ILA, with two-thirds (67%) having subpleural fibrotic abnormalities. Half of patients were referred to a Respirologist and underwent pulmonary function testing. Over a median follow-up period of two years, none were diagnosed with an idiopathic interstitial pneumonia, or started on immunomodulatory or antifibrotic therapy. Three of 30 (10%) patients demonstrated disease progression over time, all of whom had subpleural fibrotic ILA on baseline chest CT. CONCLUSIONS The prevalence of ILA in this Canadian lung cancer screening cohort was 3.7%. These data should inform the development of standardized reporting and follow-up for ILA as lung cancer screening programs are implemented.

Pulmonary arteriovenous malformations (PAVMs) affect 35–40% of individuals with HHT and can lead to recurrent embolic neurologic conditions, including stroke and transient ischemic attack (TIA), and the development of brain abscess due to intrapulmonary right-to-left shunt (RLS) in conjunction with intermittent bacteremia. METHODS A retrospective review of the Edmonton HHT Registry was conducted, where participants with possible or definite HHT were evaluated for PAVM-related neurologic conditions. RESULTS A total of 218 study subjects were included, of whom 80 had PAVMs. A trend was noted where those HHT subjects with PAVMs had a greater prevalence of stroke, TIA, migraines, seizures and brain abscess compared to those subjects with HHT who did not have PAVMs. However, the association between individual neurologic conditions and PAVMs was not statistically significant. After controlling for potential confounders of age and sex, HHT-PAVM subjects had 1.44 times the odds of associated serious neurologic condition, compared to those who did not have PAVMs (OR = 1.44, 0.74-2.78, p = 0.28). CONCLUSION Although our study did not show statistical significance, the strong positive trends suggest that PAVMs can give rise to neurologic conditions, in line with existing literature. A larger database may provide more definitive evidence. Future work should evaluate the effect of PAVM feeding artery size, architecture and shunt grade on neurologic conditions.

However, we do not know whether its management is optimal in Canada. Although guidelines are available, awareness of these and implementation of their recommendations are uncertain. OBJECTIVE The objective of this research was to evaluate the diagnostic approach and management of cough, as well as knowledge of cough guidelines in Canada. METHODS A cross-sectional online survey of general practitioners (GPs), specialists (SPs) and allied health professionals (AHPs) was conducted anonymously in Canada. Participants answered multiple-choice questions on etiology, diagnosis, follow-up and treatment (only physicians) of cough and knowledge and application of cough guidelines. MEASUREMENTS AND MAIN RESULTS A total of 248 respondents completed the survey (43 GPs, 27 SPs, and 178 AHPs). In the investigation of a patient with chronic cough, a chest radiograph was the most common test ordered by physicians (GPs: 51.2%, SPs: 59.3%) and spirometry with bronchodilator reversibility (61.2%) by AHPs. GPs most often treated cough of unknown etiology with combined inhaled corticosteroid (ICS)-long-acting β2-agonist (LABA) (25.8%) and SPs with a nasal corticosteroid (NCS)(29.8%). NCS was also the most often prescribed treatment for cough considered originating in the upper respiratory tract (GPs: 60.4%, SPs: 76.2%). When cough was believed to be due to asthma or gastroesophageal reflux disease, treatment was appropriate in most cases. Awareness of current cough guidelines content was poor in all groups (GPs: 14.0%, SPs: 51.9%, AHPs: 26.6%).
