Effects of the COVID-19 Pandemic on Respiratory Care Student Enrollment, Retention, and Success on the National Board for Respiratory Care Credentialing Examinations.

BACKGROUND: The purpose of this study was to ascertain whether the COVID-19 pandemic and the instructional changes implemented in response to it affected student enrollment, retention, or success on the National Board for Respiratory Care credentialing examinations at an associate degree respiratory care program in the state of Texas. METHODS: A retrospective analysis of student enrollment, retention data, and graduate success rates on the National Board for Respiratory Care credentialing examinations were used in this study. The data were collected from an associate degree respiratory care program in Texas and included 69 graduates for the 5-year study period. The 3 academic years that led up to the COVID-19 pandemic served as a "pre-pandemic" baseline for comparison. The cohort of 2019-2020 was labeled "early pandemic," the cohort of 2020-2021 was labeled "mid pandemic," and the cohort of 2021-2022 was labeled "late pandemic" for data comparison purposes. Descriptive statistics, the Kruskal-Wallis test, and the Mann-Whitney U test were used for data analysis (P < .05). RESULTS: The number of program applicants significantly decreased between the pre- and late-pandemic groups (P = .001), but overall student enrollment (P = .42) and retention (P = .95) were not significantly affected by the COVID-19 pandemic. The first-time pass rate on the Therapist Multiple-Choice examination low-cut score (P = .005) and high-cut score (P = .007) were significantly reduced in the mid-pandemic group when compared with the previous cohorts. There were no statistically significant differences in the demographic data or online questionnaire responses from the early- and mid-pandemic groups. CONCLUSIONS: The COVID-19 pandemic and the instructional changes implemented in response to it decreased students' first-time pass rate on the Therapist Multiple-Choice examination in the mid-pandemic group compared with the pre- and early-pandemic groups.

Treating COPD Patients with Inhaled Medications in the Era of COVID-19 and Beyond: Options and Rationales for Patients at Home.

COVID-19 has affected millions of patients, caregivers, and clinicians around the world. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spreads via droplets and close contact from person to person, and there has been an increased concern regarding aerosol drug delivery due to the potential aerosolizing of viral particles. To date, little focus has been given to aerosol drug delivery to patients with COVID-19 treated at home to minimize their hospital utilization. Since most hospitals were stressed with multiple admissions and experienced restricted healthcare resources in the era of COVID-19 pandemic, treating patients with COPD at home became essential to minimize their hospital utilization. However, guidance on how to deliver aerosolized medications safely and effectively to this patient population treated at home is still lacking. In this paper, we provide some strategies and rationales for device and interface selection, delivery technique, and infection control for patients with COPD who are being treated at home in the era of COVID-19 and beyond.

Aerosol drug delivery to tracheotomized patients with COVID-19: Pragmatic suggestions for clinicians.

Because of the wide and rapid spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the number of hospitalized patients with coronavirus disease 2019 (COVID-19) has rapidly increased medically complex and resource-intensive treatment requirements in health care settings. Although tracheostomy is frequently needed for critically ill patients requiring extended mechanical ventilation, it has been described as an aerosol-generating procedure that puts health care professionals at an increased risk of viral transmission. In addition, the delivery of aerosolized medications to this patient population has become controversial because of concerns on the transmission of SARS-CoV-2 via droplets. Although aerosol therapy in spontaneously breathing patients with COVID-19 was described in recent publications, innovations in aerosol drug delivery to COVID-19 patients with tracheostomy have not been presented. Therefore, empirically based guidance on how to deliver aerosols safely and effectively to tracheotomized patients with COVID-19 is still lacking. This paper provides recommendations and rationales for device selection, interface selection, delivery techniques, and infection control based on the evolving body of literature.

How to deliver aerosolized medications through high flow nasal cannula safely and effectively in the era of COVID-19 and beyond: A narrative review.

BACKGROUND: The treatments of COVID-19 involve some degree of uncertainty. Current evidence also shows mixed findings with regards to bioaerosol dispersion and airborne transmission of COVID-19 during high flow nasal cannula (HFNC) therapy. While coping with this global pandemic created hot debates on the use of HFNC, it is important to bring detached opinions and current evidence to the attention of health care professionals (HCPs) who may need to use HFNC in patients with COVID-19. AIM: The purpose of this paper is to provide a framework on the selection, placement, and use of nebulizers as well as HFNC prongs, gas flow, and delivery technique via HFNC to help clinicians deliver aerosolized medications through HFNC safely and effectively in the era of COVID-19 and beyond. METHODS: We searched PubMed, Medline, CINAHL, and Science Direct to identify studies on aerosol drug delivery through HFNC using the following keywords: ("aerosols," OR "nebulizers") AND ("high flow nasal cannula" OR "high flow oxygen therapy" OR "HFNC") AND ("COVID-19," OR "SARS-CoV-2"). Twenty-eight articles including in vitro studies, randomized clinical trials, scintigraphy studies, review articles, prospective and retrospective research were included in this review. DISCUSSION AND RESULTS: It is not clear if the findings of the previous studies on bacterial contamination could be applied to viral transmission because they do not provide data that could be extrapolated to the risk of SARS-CoV-2 transmission. In the face of the unknown risk with the transmission of COVID-19 during HFNC therapy, the benefits of HFNC must be weighed against the risk of infection to HCPs and other patients. Due to the limited number of ventilators available in hospitals and the confirmed effectiveness of HFNC in treating hypoxemic respiratory failure, HFNC may prevent early intubation, and prolonged intensive care unit stays in patients with COVID-19. CONCLUSION: Clinicians should review the magnitude of this risk based on current evidence and use the suggested strategies of this paper for safe and effective delivery of aerosolized medications through HFNC in the era of COVID-19 and beyond.

Practical strategies for a safe and effective delivery of aerosolized medications to patients with COVID-19

The COVID-19, the disease caused by a novel coronavirus and named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has spread rapidly across the globe. It has caused outbreaks of illness due to person-to-person transmission of the virus mainly via close contacts and droplets produced by an infected person's cough or sneeze. Exhaled droplets from infected patients with COVID-19 can be inhaled into the lungs and leads to respiratory illness such as pneumonia and acute respiratory distress syndrome. Although aerosol therapy is a mainstay procedure used to treat pulmonary diseases at home and healthcare settings, it has a potential for fugitive emissions during therapy due to the generation of aerosols and droplets as a source of respiratory pathogens. Delivering aerosolized medications to patients with COVID-19 can aggravate the spread of the novel coronavirus. This has been a real concern for caregivers and healthcare professionals who are susceptible to unintended inhalation of fugitive emissions during therapy. Due to a scarcity of information in this area of clinical practice, the purpose of this paper is to explain how to deliver aerosolized medications to mild-, sub-intensive, and intensive patients with COVID-19 and how to protect staff from exposure to exhaled droplets during aerosol therapy.
