Short-Term Health Outcomes of a Structured Pulmonary Rehabilitation Program Implemented Within Rural Canadian Sites Compared With an Established Urban Site: A Pre-Post Intervention Observational Study.

OBJECTIVES: To evaluate congruence in program delivery and short-term health outcomes of a structured pulmonary rehabilitation (S-PR) program implemented at 11 Canadian rural pulmonary rehabilitation (PR) sites compared with an urban reference site. DESIGN: Multi-center, pre- and post-intervention, comparative, observational study. SETTING: Eleven rural Canadian PR sites and 1 urban reference PR site. PARTICIPANTS: Adults with chronic respiratory diseases (CRDs) referred to PR. INTERVENTION: Clinicians at the reference site worked with local clinicians to implement the S-PR program in rural sites. A PR survey evaluated site congruence with the S-PR components, with congruence defined as delivering program components ≥80% in alignment with the S-PR program. Participants were enrolled in 16 sessions of group education and supervised exercise, offered twice or thrice a week. Health outcomes were tracked using a quality assurance database. OUTCOME MEASURES: Main outcomes were congruence in program delivery and changes in the 6-minute walk (6MW) distance and COPD Assessment Test (CAT). RESULTS: A total of 555 participants (rural n=204 and reference n=351) were included in the analyses. There was congruence in exercise and group education; however, individual education varied. Following the S-PR program, 6MW distance increased, with greater changes observed at rural sites (51±67 m at rural sites vs 30±46 m at the reference site). CAT score was reduced by -2.6±5.4 points with no difference between reference and rural sites. Changes in 6MW distance and CAT scores were similar for participants at sites that were congruent vs noncongruent with the individual education component, and similar for patients with COPD, asthma, bronchiectasis, and interstitial lung disease. CONCLUSION: The S-PR program components can be implemented with good congruence in Canadian rural settings, resulting in similar short-term health outcomes as in an established urban site and across CRDs.

The Respiratory Therapy Practice-Based Outcomes Initiative (RT-PBOI): Developing a framework to explore the value added by respiratory therapists to health care in Alberta.

BACKGROUND: There exists a political imperative to have access to data that meets the needs of health care administrators, governments, and funding bodies to support evidence-informed decision making. It is incumbent upon respiratory therapists to examine how they can deliver the highest-quality patient care, but also that they add value to health systems that ensure the benefits of health innovations are shared equitably among all members of our communities. PURPOSE: To explore the perceived value contributed by the respiratory therapy profession to health care and the health care system in the Province of Alberta at patient, team, and system levels. RESEARCH METHODS: An interpretive descriptive approach was adopted, including the formation of a description and exploration of possible associations, relationships, and patterns within a field of practice. CONCLUSIONS: The qualitative data analysis uncovered a framework that could inform research efforts of the respiratory therapy community in a way that contributes to the proposed mechanisms by which the profession generates value for the organization and patients. The RT-PBOI Conceptual Model identified five key concepts relating to the value contributed by respiratory therapists to health care: technical skills, practice across settings, strategic expertise, tools that leverage capacity, and growing value into the future.

Risk of transmission of respiratory viruses during aerosol-generating medical procedures (AGMPs) revisited in the COVID-19 pandemic: a systematic review.

BACKGROUND: In many jurisdictions healthcare workers (HCWs) are using respirators for aerosol-generating medical procedures (AGMPs) performed on adult and pediatric populations with all suspect/confirmed viral respiratory infections (VRIs). This systematic review assessed the risk of VRIs to HCWs in the presence of AGMPs, the role respirators versus medical/surgical masks have on reducing that risk, and if the risk to HCWs during AGMPs differed when caring for adult or pediatric patient populations. MAIN TEXT: We searched MEDLINE, EMBASE, Cochrane Central, Cochrane SR, CINAHL, COVID-19 specific resources, and MedRxiv for English and French articles from database inception to September 9, 2021. Independent reviewers screened abstracts using pre-defined criteria, reviewed full-text articles, selected relevant studies, abstracted data, and conducted quality assessments of all studies using the ROBINS-I risk of bias tool. Disagreements were resolved by consensus. Thirty-eight studies were included; 23 studies on COVID-19, 10 on SARS, and 5 on MERS/ influenza/other respiratory viruses. Two of the 16 studies which assessed associations found that HCWs were 1.7 to 2.5 times more likely to contract COVID-19 after exposure to AGMPs vs. not exposed to AGMPs. Eight studies reported statistically significant associations for nine specific AGMPs and transmission of SARS to HCWS. Intubation was consistently associated with an increased risk of SARS. HCWs were more likely (OR 2.05, 95% CI 1.2-3.4) to contract human coronaviruses when exposed to an AGMP in one study. There were no reported associations between AGMP exposure and transmission of influenza or in a single study on MERS. There was limited evidence supporting the use of a respirator over a medical/surgical mask during an AGMP to reduce the risk of viral transmission. One study described outcomes of HCWs exposed to a pediatric patient during intubation. CONCLUSION: Exposure to an AGMP may increase the risk of transmission of COVID-19, SARS, and human coronaviruses to HCWs, however the evidence base is heterogenous and prone to confounding, particularly related to COVID-19. There continues to be a significant research gap in the epidemiology of the risk of VRIs among HCWs during AGMPs, particularly for pediatric patients. Further evidence is needed regarding what constitutes an AGMP.
