Observational Study
A Retrospective Observational Study of Domiciliary Oxygen Usage in a Subset of Veterans.
Long-term oxygen therapy (LTOT) delivered continuously is known to decrease mortality in patients with COPD and who are hypoxemic; however, supportive data for LTOT use in patients without COPD is lacking. In addition, many patients may be prescribed LTOT without a definitive etiology for hypoxemia. First, we investigated the diagnoses for which oxygen was prescribed to a sample of veterans and whether each diagnosis was supported by confirmatory testing. Second, we looked at the proportion of subjects who were prescribed non-continuous therapy. ⋯ Results of our study showed a 99.4% adherence to Medicare criteria for domiciliary oxygen prescription. Also, 30.3% of the subjects were prescribed LTOT for exertional or nocturnal desaturation or both. Repeated testing at 3 months identified subjects who no longer required oxygen. COPD was the most common etiology for domiciliary oxygen. A small proportion of the subjects (6.9%) were prescribed oxygen without underlying etiology for hypoxia. Exertional and/or nocturnal oxygen prescription was common, and further research to elucidate its utility is clearly warranted.

While medication is an integral component of the effective management of COPD, contemporary studies report that more than half of all people who are prescribed medication for the management of their COPD do not adhere to therapy. Enhancing medication adherence and improving health outcomes for those living with COPD are among the key challenges for the global health community. This systematic review aims to identify the rate of nonadherence among people who are prescribed controller medication for the management of their COPD, and identifies the barriers and facilitators that influence their medication use behavior. ⋯ Adherence to COPD medication was generally low, with the majority of studies identifying the presence of depression and subjects' concern about the harmful effects of the medicine as barriers to adherence. Variability exists on the reported rates of nonadherence, possibly due to different measures utilized to assess adherence. Future research in low-income nations is needed.

COVID-19 has impacted how we deliver care to patients, and much remains unknown regarding optimal management of respiratory failure in this patient population. There are significant controversies regarding tracheostomy in patients with COVID-19 related to timing, location of procedure, and technique. ⋯ Consensus can be reached that patients with COVID-19 should be managed in a negative-pressure environment with proper personal protective equipment, and that performing tracheostomy is a complex decision that should be made through multidisciplinary discussions considering patient prognosis, institutional resources, staff experience, and risks to essential health care workers. A broad range of practices exist because there is no conclusive guidance regarding the optimal timing or technique for tracheostomy.
