Models Used by Nurse Case Managers in Different Autonomous Communities in Spain: A Scoping Review.

(1) Background: The role of the nurse case manager is unknown to the population. The main objective is to analyze the existing differences within the national territory in order to make known the situation in Spain with a view to the recognition of its functions and the creation of the professional profile in an equal manner. (2) Methods: A scoping review was conducted in order to achieve the main aim. Selected articles were subjected to a critical reading, and the levels of evidence and grades of recommendation of the Joanna Briggs Institute were verified. The search field was limited to the last ten years. (3) Results: Case management models are heterogeneous in different autonomous communities in Spain. Case nurse management is qualified for high-complexity patients, follow up on chronic patients, and coordinate health assistance. (4) Conclusions: It concludes that nursing's role is crucial in the field of case management, being required in the follow-up of chronic patients of high complexity. Despite the proven health benefits, efficacy, and efficiency of case management, there are many heterogeneous models that coexist in Spain. This involves a restriction in the development of a nursing career because of the lack of a definition of its functions and competences.

Exercise Ventilatory Inefficiency in Post-COVID-19 Syndrome: Insights from a Prospective Evaluation.

INTRODUCTION: Coronavirus disease 2019 (COVID-19) is a systemic disease characterized by a disproportionate inflammatory response in the acute phase. This study sought to identify clinical sequelae and their potential mechanism. METHODS: We conducted a prospective single-center study (NCT04689490) of previously hospitalized COVID-19 patients with and without dyspnea during mid-term follow-up. An outpatient group was also evaluated. They underwent serial testing with a cardiopulmonary exercise test (CPET), transthoracic echocardiogram, pulmonary lung test, six-minute walking test, serum biomarker analysis, and quality of life questionaries. RESULTS: Patients with dyspnea (n = 41, 58.6%), compared with asymptomatic patients (n = 29, 41.4%), had a higher proportion of females (73.2 vs. 51.7%; p = 0.065) with comparable age and prevalence of cardiovascular risk factors. There were no significant differences in the transthoracic echocardiogram and pulmonary function test. Patients who complained of persistent dyspnea had a significant decline in predicted peak VO2 consumption (77.8 (64-92.5) vs. 99 (88-105); p < 0.00; p < 0.001), total distance in the six-minute walking test (535 (467-600) vs. 611 (550-650) meters; p = 0.001), and quality of life (KCCQ-23 60.1 ± 18.6 vs. 82.8 ± 11.3; p < 0.001). Additionally, abnormalities in CPET were suggestive of an impaired ventilatory efficiency (VE/VCO2 slope 32 (28.1-37.4) vs. 29.4 (26.9-31.4); p = 0.022) and high PETCO2 (34.5 (32-39) vs. 38 (36-40); p = 0.025). INTERPRETATION: In this study, >50% of COVID-19 survivors present a symptomatic functional impairment irrespective of age or prior hospitalization. Our findings suggest a potential ventilation/perfusion mismatch or hyperventilation syndrome.
