Abstract
This Thoracic Society of Australia and New Zealand Guideline on the provision of home oxygen therapy in adults updates a previous Guideline from 2015. The Guideline is based upon a systematic review and meta-analysis of literature to September 2022 and the strength of recommendations is based on GRADE methodology. Long-term oxygen therapy (LTOT) is recommended for its mortality benefit for patients with COPD and other chronic respiratory diseases who have consistent evidence of significant hypoxaemia at rest (PaO2 ≤ 55 mm Hg or PaO2 ≤59 mm Hg in the presence of hypoxaemic sequalae) while in a stable state. Evidence does not support the use of LTOT for patients with COPD who have moderate hypoxaemia or isolated nocturnal hypoxaemia. In the absence of hypoxaemia, there is no evidence that oxygen provides greater palliation of breathlessness than air. Evidence does not support the use of supplemental oxygen therapy during pulmonary rehabilitation in those with COPD and exertional desaturation but normal resting arterial blood gases. Both positive and negative effects of LTOT have been described, including on quality of life. Education about how and when to use oxygen therapy in order to maximize its benefits, including the use of different delivery devices, expectations and limitations of therapy and information about hazards and risks associated with its use are key when embarking upon this treatment.

Abstract
Home oxygen therapy (HOT) is prescribed to patients with pulmonary dysfunction to improve survival and quality of life. However, ignition of oxygen can lead to burns with significant morbidity and mortality. Providers who routinely treat this patient population face an ethical issue: balancing the obligation to provide beneficial treatment to a patient with the responsibility to protect that patient from suffering avoidable burn injuries. A thorough review was conducted to assess the literature regarding ethical considerations involved in managing patients who have been burned while smoking on HOT and who continue to smoke. Various aspects of this problem and potential approaches to address it were analyzed with respect to 4 core ethical principles of health care: beneficence, nonmaleficence, autonomy, and justice. For patients who repeatedly present with burns acquired secondary to smoking while on oxygen, the authors consider it ethically unacceptable to withhold standard-of-care intervention for acute burns because refusal to treat acute burns conflicts with all 4 ethical principles. A preventive strategy would encourage a more judicious prescription of HOT, supporting the principles of nonmaleficence and beneficence. Additional preventive strategies include upstream solutions such as longitudinal patient education about smoking cessation and the risks of smoking on HOT. Physicians are tasked with the responsibility of both providing optimal care for this patient population and preventing future burn injuries. They may be able to address this challenging situation by thinking more critically about potential solutions while bearing in mind key ethical considerations and obligations.

Abstract
Burns in the elderly are a significant cause of morbidity and mortality. Frailty is an important indicator of patient health and physiologic reserve. Comorbidities and typical age-related changes significantly impact the outcomes of elderly burn patients and decisions made during their burn care. It is essential to have early and thorough discussions about the goals of care and rehabilitation plans. Physiologic changes that occur from aging cause slower wound healing and may make operative treatment more challenging, although techniques such as autographing, skin substitutes, and flaps may all play a role in treating this patient population.

Abstract
The presence of any comorbid condition may lead to worse outcomes after burn injury. Chronic obstructive pulmonary disease (COPD) is a condition with significant morbidity and mortality. In 2018, about 16 million adults in the United States reported a diagnosis of COPD based on data from the American Lung Association. The objective of this study was to explore the outcomes of patients with COPD admitted to our Burn Center with flame burns and/or inhalation injury. Patients were identified using our Institutional Burn Center registry and linked to the clinical and administrative data. All adult flame-injured and/or inhalation injury-only patients admitted to our burn center between July 1, 2011 and June 30, 2020 were included. Demographics, length of stay, burn, and patient characteristics and outcomes, including mortality, were evaluated. Four thousand three hundred ninety-seven patients were included in the study. Patients were divided into two populations, those with COPD (n = 515) and those without a diagnosis of COPD (n = 3882). Patients with COPD were older, more likely to be white and male, and had smaller sized burns, p < .001. Patients with COPD were more likely to be smokers and have comorbid conditions. There was no statistically significant difference between the incidence of inhalation injury, lengths of stay, or number of ventilator days. Burn size and inhalation injury increased mortality risk regardless of COPD severity, as did age among those not on home oxygen. More studies are needed to determine the genomic or proteomic changes in patients with COPD that lead to worse outcomes after flame injury, and/or inhalation injury alone.

Abstract
Abstract
Home oxygen therapy (HOT) burns carry high morbidity and mortality. Many patients are active smokers, which is the most frequent cause of oxygen ignition. We conducted a retrospective review at our institution to characterize demographics and outcomes in this patient population. An IRB-approved single-institution retrospective review was conducted for home oxygen therapy burn patients between July 2016 and January 2021. Demographic and clinical outcome data were compared between groups. We identified 100 patients with oxygen therapy burns. Mean age was 66.6 years with a male to female ratio of 1.3:1 and median burn surface area of 1%. In these patients, 97% were on oxygen for COPD and smoking caused 83% of burns. Thirteen were discharged from the emergency department, 35 observed for less than 24 hours, and 52 admitted. For admitted patients, 69.2% were admitted to the ICU, 37% required intubation, and 11.5% required debridement and grafting. Inhalational injury was found in 26.9% of patients, 3.9% underwent tracheostomy, and 17.3% experienced hospital complications. In-hospital mortality was 9.6% and 7.7% were discharged to hospice. 13.5% required readmission within 30 days. Admitted patients had significantly higher rates of admission to the ICU, intubation, and inhalational injury compared to those that were not admitted (p < .01). Most HOT-related burns are caused by smoking and can result in significant morbidity and mortality. Efforts to educate and encourage smoking cessation with more judicious HOT allocation would assist in preventing these unnecessary highly morbid injuries.

Abstract
There is an increased risk for burn injuries associated with home oxygen therapy of patients with chronic obstructive pulmonary disease since 10 to 50 % of these patients continue to smoke. Enzymatic eschar removal of facial burns is gaining popularity but intubation of this specific patient group often leads to prolonged weaning and can require tracheostomy. This study dealt with the question if enzymatic debridement in these patients can also be performed in analgosedation. A selective review of the literature regarding burn trauma associated with home oxygen use in patients with COPD was performed, as well as a retrospective analysis of all patients with burn injuries associated with home oxygen use and chronic obstructive pulmonary disease that were admitted to the study clinic. In the literature 1746 patients with burns associated with home oxygen use are described, but none of them received enzymatic debridement. In this study seventeen patients were included. All three patients in this study with facial full-thickness burn injuries received enzymatic debridement. The mortality rate in this cohort was 17.6 % (3/17). Up to date, there is limited experience performing regional anesthesia debridement in patients with COPD. This is the first manuscript describing the use of enzymatic debridement in patients with COPD and home oxygen therapy. We could confirm other studies that intubation of these patients leads to prolonged ventilation hours and increases the probability for poor prognosis. Therefore, we described the treatment of enzymatic debridement in analgosedation without intubation.

Abstract
Background: Evidence-based guidelines are needed for effective delivery of home oxygen therapy to appropriate patients with chronic obstructive pulmonary disease (COPD) and interstitial lung disease (ILD).Methods: The multidisciplinary panel created six research questions using a modified Delphi approach. A systematic review of the literature was completed, and the Grading of Recommendations Assessment, Development and Evaluation approach was used to formulate clinical recommendations.Recommendations: The panel found varying quality and availability of evidence and made the following judgments: 1) strong recommendations for long-term oxygen use in patients with COPD (moderate-quality evidence) or ILD (low-quality evidence) with severe chronic resting hypoxemia, 2) a conditional recommendation against long-term oxygen use in patients with COPD with moderate chronic resting hypoxemia, 3) conditional recommendations for ambulatory oxygen use in patients with COPD (moderate-quality evidence) or ILD (low-quality evidence) with severe exertional hypoxemia, 4) a conditional recommendation for ambulatory liquid-oxygen use in patients who are mobile outside the home and require >3 L/min of continuous-flow oxygen during exertion (very-low-quality evidence), and 5) a recommendation that patients and their caregivers receive education on oxygen equipment and safety (best-practice statement).Conclusions: These guidelines provide the basis for evidence-based use of home oxygen therapy in adults with COPD or ILD but also highlight the need for additional research to guide clinical practice.

Abstract
Introduction Two large major trials showed that long-term oxygen therapy (LTOT) improved mortality in patients with chronic obstructive pulmonary disease (COPD) and hypoxemia. Although oxygen accelerates combustion and is an obvious fire hazard, LTOT has traditionally been prescribed to veterans who are actively smoking. Methods We conducted a retrospective chart review of all veterans with COPD at a single center who were prescribed new LTOT between October 2010 and September 2015. Of the 158 patients who met the study criteria, 152 were male. Bayesian logistic regression was used to model the outcome variable fire-related incident with the predictors smoking status, age, race, depression, posttraumatic stress disorder, and type of oxygen used. Results The mean age of the 158 patients with COPD in the study was 71.3 years in nonsmokers and 65.9 years in smokers. The model-estimated odds (SD) of a fire-related incident occurring in a smoker were 31.6 (5.1-372.7) times the odds of a fire-related incident occurring in a nonsmoker. Conclusions Patients who smoke and remain on LTOT put themselves at greater risk of having a fire-related incident than do nonsmokers.

Abstract
Abstract
The Boston Criteria and the Abbreviated Burn Severity Index are two widely accepted models for predicting mortality in burn patients. We aimed to elucidate whether these models are able to predict the risk of mortality in patients who sustain burns while smoking on home oxygen given their clinical fragility. We conducted a retrospective chart review of 48 patients admitted to our burn center from November 2013 to September 2017 who sustained a burn while smoking on home oxygen. Yearlong mortality was the primary outcome of the investigation; secondary outcomes included discharge to facility, length of stay, and need for tracheostomy. We calculated the expected mortality rate for each patient based on Boston Criteria and Abbreviated Burn Severity Index and compared the mortality rate observed in our cohort. Patients in our cohort suffered a 54% mortality rate within a year of injury, compared to a 23.5% mortality predicted by Boston Criteria, which was found to be statistically significant by chi-square analysis (P < .05). Abbreviated Burn Severity Index predicted mortality was 19.7%. While the absolute value of the difference in mortality was greater, this was not significant on chi-square analysis due to sample size. Our secondary outcomes revealed 42% discharge to facility, the average length of stay of 6.2 days, and 6.25% required tracheostomy. Patients whose burns are attributable to smoking on home oxygen may have an increased risk of mortality than prognostication models would suggest. This bears significant clinical impact, particularly regarding family and provider decision making in pursuing aggressive management.

Abstract
Two landmark trials conducted more than 35 years ago provided scientific evidence that, under very specific circumstances, long-term oxygen therapy (LTOT) may prolong life. These two trials enrolled 290 patients with chronic obstructive pulmonary disease and severe daytime hypoxemia documented by direct arterial blood gas measurement. From that time, LTOT became a standard of care, and the indications for oxygen therapy expanded to include nocturnal oxygen therapy for isolated nocturnal oxygen desaturation, ambulatory oxygen to correct exercise-induced desaturation, and short-burst oxygen to relieve dyspnea. In most cases, the rationale for broadening the indications for oxygen therapy is that, if hypoxemia exists, correcting it by increasing the FiO2 should help. However, with the exception of LTOT in severely hypoxemic patients with chronic obstructive pulmonary disease, randomized controlled trials of oxygen therapy have failed to demonstrate clinically significant benefits. Also, adherence to LTOT is usually suboptimal. Important areas for future research include improving understanding of the mechanisms of action of supplemental oxygen, the clinical and biochemical predictors of responsiveness to LTOT, the methods for measuring and enhancing adherence to LTOT, and the cost-effectiveness of oxygen therapy. A standardization of terminology to describe the use of supplemental oxygen at home is provided.

Ensuring equitable access to quality health care historically has focused on gaps in care, where patients fail to receive the high-value care that will benefit them, something termed underuse. But providing high-quality health care sometimes requires reducing low-value care that delivers no benefit or where known harms outweigh expected benefits. These situations represent health care overuse. The process involved in reducing low-value care is known as de-implementation. In this article, we argue that de-implementation is critical for advancing equity for several reasons. First, medical overuse is associated with patient race, ethnicity, and socioeconomic status. In some cases, the result is even double jeopardy, where racial and ethnic minorities are at higher risk of both overuse and underuse. In these cases, more traditional efforts focused exclusively on underuse ignore half of the problem. Second, overuse of preventive care and screening is often greater for more socioeconomically advantaged patients. Within insured populations, this means more socioeconomically disadvantaged patients subsidize overuse. Finally, racial and ethnic minorities may have different experiences of overuse than Whites in the United States. This may make efforts to de-implement overuse particularly fraught. We therefore provide several actions for closing current research gaps, including: adding subgroup analyses in studies of medical overuse; specifying and measuring potential mechanisms related to equity (eg, double jeopardy vs thermostat models of overuse); and testing de-implementation strategies that may mitigate bias.

Abstract
PURPOSE OF REVIEW Oxygen therapy was the first treatment shown to prolong life in patients with chronic obstructive pulmonary disease (COPD) and has been joined by lung volume reduction surgery in selected patients with emphysema, smoking cessation, and potentially noninvasive ventilation in chronic hypercapneic respiratory failure. Although there is consensus around the survival-enhancing effect of supplemental oxygen (SupplO2) for patients with chronic severe hypoxemia at rest, the impact of SupplO2 for COPD patients with moderate hypoxemia and exertional desaturation had been less clear. RECENT FINDINGS The recently published Long-term Oxygen Treatment Trial (LOTT) showed no benefit of SupplO2 for the composite outcome of survival and all-cause hospitalizations, or for component outcomes, severe COPD exacerbations, or quality of life in COPD patients with moderate resting hypoxemia or room air normoxemia with exercise desaturation. SUMMARY Results of the LOTT challenge the practice of prescribing SupplO2 for patients with COPD and moderate resting hypoxemia or isolated exertional desaturation. In the context that LOTT may not have recruited patients for whom SupplO2 conferred subjective benefit, there may be a role for short-term trials of SupplO2 with assessment of subjective benefit in such patients.

Abstract
Background Long-term oxygen therapy (LTOT) improves prognosis in COPD with severe hypoxemia. However, adherence to criteria for eligibility and quality of LTOT is often insufficient and varies between countries. The aim of this study was to evaluate a national structure for prescription and management of LTOT over three decades in Sweden. Methods The study was a prospective, population-based study of 23,909 patients on LTOT from 1987 to 2015 in the Swedish National Register of Respiratory Failure (Swedevox). We assessed the prevalence, incidence, and structure of LTOT; completeness of registration in Swedevox; and validity of prescription and management of LTOT in Sweden according to seven published quality indicators. Results LTOT was prescribed by 48 respiratory or medicine units and managed mainly by specialized oxygen nurses. Swedevox had a stable completeness of 85% of patients starting LTOT since 1987. The national incidence of LTOT increased from 3.9 to 14.7/100,000 inhabitants over the time period. In 2015, 2,596 patients had ongoing therapeutic LTOT in the registry, a national prevalence of 31.6/100,000. Adherence to prescription recommendations and fulfillment of quality criteria was stable or improved over time. Of patients starting LTOT in 2015, 88% had severe hypoxemia (partial pressure of arterial oxygen [PaO2] <7.4 kPa) and 97% had any degree of hypoxemia (PaO2 <8.0 kPa); 98% were prescribed oxygen ≥15 hours/day or more; 76% had both stationary and mobile oxygen equipment; 75% had a mean PaO2 >8.0 kPa breathing oxygen; and 98% were non-smokers. Conclusion We present a structure for prescription, management, and follow-up of LTOT. The national registry effectively monitored adherence to prescription recommendations and most likely contributed to improved quality of care.

Abstract
INTRODUCTION Burns cause physiologic changes in multiple organ systems in the body. Burn mortality is usually attributable to pulmonary complications, which can occur in up to 41% of patients admitted to the hospital after burn. Patients with preexisting comorbidities such as chronic lung diseases may be more susceptible. We therefore sought to examine the impact of preexisting respiratory disease on burn outcomes. METHODS A retrospective analysis of patients admitted to a regional burn center from 2002-2012. Independent variables analyzed included basic demographics, burn mechanism, presence of inhalation injury, TBSA, pre-existing comorbidities, smoker status, length of hospital stay, and days of mechanical ventilation. Bivariate analysis was performed and Cox regression modeling using significant variables was utilized to estimate hazard of progression to mechanical ventilation and mortality. RESULTS There were a total of 7640 patients over the study period. Overall survival rate was 96%. 8% (n=672) had a preexisting respiratory disease. Chronic lung disease patients had a higher mortality rate (7%) compared to those without lung disease (4%, p<0.01). The adjusted Cox regression model to estimate the hazard of progression to mechanical ventilation in patients with respiratory disease was 21% higher compared to those without respiratory disease (HR=1.21, 95% CI=1.01-1.44). The hazard of progression to mortality is 56% higher (HR=1.56, 95% CI=1.10-2.19) for patients with pre-existing respiratory disease compared to those without respiratory disease after controlling for patient demographics and injury characteristics. CONCLUSION Preexisting chronic respiratory disease significantly increases the hazard of progression to mechanical ventilation and mortality in patients following burn. Given the increasing number of Americans with chronic respiratory diseases, there will likely be a greater number of individuals at risk for worse outcomes following burn.

Abstract
The global burden of chronic obstructive pulmonary disease (COPD) continues to grow in part due to better outcomes in other major diseases and in part because a substantial portion of the worldwide population continues to be exposed to inhalant toxins. However, a disproportionate burden of COPD occurs in people of low socioeconomic status (SES) due to differences in health behaviors, sociopolitical factors, and social and structural environmental exposures. Tobacco use, occupations with exposure to inhalant toxins, and indoor biomass fuel (BF) exposure are more common in low SES populations. Not only does SES affect the risk of developing COPD and etiologies, it is also associated with worsened COPD health outcomes. Effective interventions in these people are needed to decrease these disparities. Efforts that may help lessen these health inequities in low SES include 1) better surveillance targeting diagnosed and undiagnosed COPD in disadvantaged people, 2) educating the public and those involved in health care provision about the disease, 3) improving access to cost-effective and affordable health care, and 4) markedly increasing the efforts to prevent disease through smoking cessation, minimizing use and exposure to BF, and decreasing occupational exposures. COPD is considered to be one the most preventable major causes of death from a chronic disease in the world; therefore, effective interventions could have a major impact on reducing the global burden of the disease, especially in socioeconomically disadvantaged populations.

Abstract
PURPOSE We aimed to investigate the association between psychotropic treatment and risk of burn injury in individuals with mental illness. METHODS A nested case-control study was conducted by using the National Health Insurance Research Database in Taiwan. A total of 3187 cases with burn injury under International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes 940-949 and 19 122 matched controls were identified from 2003 to 2012. Four kinds of psychotropic agents (antipsychotics (APs), antidepressants (ADs), benzodiazepines, and z-drugs) were examined. Psychotropic exposure status was measured, and a set of potential confounding factors was adjusted in the analyses. Conditional logistic regressions were applied to determine the effect of psychotropic use on burn injury. RESULTS A significant increased risk of burn injury was observed among psychotropic users compared with non-users (adjusted odds ratio (AOR) = 1.45, 95%CI = 1.31-1.61). When classifying psychotropic users into current, new, continuous, and past users, a significant elevated risk of burn injury was found across all groups (AOR = 1.76, 95%CI = 1.54-2.00 in current users; AOR = 2.02, 95%CI = 1.55-2.65 in new users; AOR = 1.72, 95%CI = 1.50-1.96 in continuous users; and AOR = 1.35, 95%CI = 1.21-1.51 in past users). When assessing each individual kind of examined psychotropic agents, a significant elevated risk of burn injury was found among users of APs, ADs, benzodiazepines, and z-drugs except for current and continuous users of z-drugs. CONCLUSIONS The results demonstrate an elevated risk of burn injury among individuals with current psychotropic use. The findings underscore the need for greater attention to be given to the cognitive performance and psychomotor abilities of individuals taking psychotropic medications in order to prevent the occurrence of burn injury.

Abstract
The objective was to analyze reported flash burns experienced by patients on home oxygen therapy (HOT) in the Veterans Health Administration (VHA) using a qualitative, retrospective review of VHA root cause analysis reports between January 2009 and November 2015. Of 123 cases of reported adverse events related to flash burns, 100 cases (81%) resulted in injury, and 23 (19%) resulted in death. Although 89% of veterans claimed to have quit smoking (n = 109), 92% (n = 113) of burns occurred as a result of smoking. The most common root cause was risk identification issues. Recommended actions were standardized risk assessment policies, patient education, and the adoption of fire stop valves. Patients with a history of smoking who are on HOT should be considered for fire stop valves and offered consistent counseling and follow-up using a combination of harm reduction and shared decision-making techniques. Standardization of risk identification and documentation is recommended.

Abstract
BACKGROUND Long-term oxygen therapy (LTOT) improves the survival time in hypoxemic chronic obstructive pulmonary disease. Despite warnings about potential dangers, a considerable number of patients continue to smoke while on LTOT. The incidence of burn injuries related to LTOT is unknown. The aim of this study was to estimate the rate of burn injury requiring health care contact during LTOT. METHODS Prospective, population-based, consecutive cohort study of people starting LTOT from any cause between January 1, 1992 and December 31, 2009 in the Swedish National Register of Respiratory Failure (Swedevox). RESULTS In total, 12,497 patients (53% women) were included. The mean (standard deviation) age was 72±9 years. The main reasons for starting LTOT were chronic obstructive pulmonary disease (75%) and pulmonary fibrosis (15%). Only 269 (2%) were active smokers when LTOT was initiated. The median follow-up time to event was 1.5 years (interquartile range, 0.55-3.1). In total, 17 patients had a diagnosed burn injury during 27,890 person-years of LTOT. The rate of burn injury was 61 (95% confidence interval, 36-98) per 100,000 person-years. There was no statistically significant difference in the rate of burn injury between ever-smokers and never-smokers, or between men and women. CONCLUSION The rate of burn injuries in patients on LTOT seems to be low in Sweden. The strict requirements in Sweden for smoking cessation before LTOT initiation may contribute to this finding.
