Causes and Risk Factors for Absenteeism among Medical Staff in German Specialized Lung Clinics during the COVID Pandemic.

BACKGROUND: Staff shortages pose a major challenge to the health system. OBJECTIVES: The objective of this study was to clarify the role of different causative factors we investigated on staff absenteeism during the COVID pandemic. METHODS: The prospective multicentre cohort study assessed the private and professional impact of the pandemic on health care workers (HCWs) using a specially developed questionnaire. HCWs from 7 specialist lung clinics throughout Germany were surveyed from December 1 to December 23, 2021. The current analysis addresses pandemic-related absenteeism. RESULTS: 1,134 HCW (55% female; 18.4% male, 26.3% not willing to provide information on age or gender) participated. 72.8% had received at least one vaccination dose at the time of the survey, and 9.4% reported a COVID infection. Of those with positive tests, 98% reported home quarantine for median (IQR) 14 (12-17) days; 10.3% of those who ultimately tested negative also reported quarantine periods of 14 (7-14) days. 32.2% of vaccinated respondents reported absenteeism due to vaccine reactions of 2 (1-3) days. Overall, 37% (n = 420) of HCW reported pandemic-related absenteeism, with 3,524 total days of absenteeism, of which 2,828 were due to illness/quarantine and 696 to vaccination effects. Independent risk factors for COVID-related absenteeism ≥5 days included already having COVID, but also concern about long-term effects of COVID (OR 1,782, p = 0.014); risk factors for vaccine-related absenteeism ≥2 days included concerns of late effects of vaccination (OR 2.2, 95% CI: 1.4-3.1, p < 0.000). CONCLUSION: Staff shortages due to quarantine or infections and vaccine reactogenicity have put a strain on German respiratory specialists. The fact that staff concerns also contributed to absenteeism may be helpful in managing future pandemic events to minimize staff absenteeism.

Gender Differences in Health Care Workers' Risk-Benefit Trade-Offs for COVID-19 Vaccination.

BACKGROUND: Gender differences in vaccine acceptance among health care workers (HCWs) are well documented, but the extent to which these depend on occupational group membership is less well studied. We aimed to determine vaccine acceptance and reasons of hesitancy among HCWs of respiratory clinics in Germany with respect to gender and occupational group membership. METHODS: An online questionnaire for hospital staff of all professional groups was created to assess experiences with and attitudes towards COVID-19 and the available vaccines. Employees of five clinics were surveyed from 15 to 28 March 2021. RESULTS: 962 employees (565 [72%] female) took part in the survey. Overall vaccination acceptance was 72.8%. Nurses and physicians showed greater willingness to be vaccinated than members of other professions (72.8%, 84.5%, 65.8%, respectively; p = 0.006). In multivariate analyses, worries about COVID-19 late effects (odds ratio (OR) 2.86; p < 0.001) and affiliation with physicians (OR 2.20; p = 0.025) were independently associated with the willingness for vaccination, whereas age <35 years (OR 0.61; p = 0.022) and worries about late effects of vaccination (OR 0.13; p < 0.001) predicted vaccination hesitancy; no differences were seen with respect to gender. In separate analyses for men and women, only for men worries about COVID-19 late effects were relevant, while among women, age <35 years, worries about late effects of vaccination and worries about COVID-19 late effects played a role. CONCLUSIONS: There was no overall difference in vaccination acceptance between male and female HCWs, but there were gender-specific differences in the individual reasons on which this decision-making was based.

Pulmonary Hypertension in Adults with Congenital Heart Disease: Real-World Data from the International COMPERA-CHD Registry.

INTRODUCTION: Pulmonary hypertension (PH) is a common complication in patients with congenital heart disease (CHD), aggravating the natural, post-operative, or post-interventional course of the underlying anomaly. The various CHDs differ substantially in characteristics, functionality, and clinical outcomes among each other and compared with other diseases with pulmonary hypertension. OBJECTIVE: To describe current management strategies and outcomes for adults with PH in relation to different types of CHD based on real-world data. METHODS AND RESULTS: COMPERA (Comparative, Prospective Registry of Newly Initiated Therapies for Pulmonary Hypertension) is a prospective, international PH registry comprising, at the time of data analysis, >8200 patients with various forms of PH. Here, we analyzed a subgroup of 680 patients with PH due to CHD, who were included between 2007 and 2018 in 49 specialized centers for PH and/or CHD located in 11 European countries. At enrollment, the patients´ median age was 44 years (67% female), and patients had either pre-tricuspid shunts, post-tricuspid shunts, complex CHD, congenital left heart or aortic disease, or miscellaneous other types of CHD. Upon inclusion, targeted therapies for pulmonary arterial hypertension (PAH) included endothelin receptor antagonists, PDE-5 inhibitors, prostacyclin analogues, and soluble guanylate cyclase stimulators. Eighty patients with Eisenmenger syndrome were treatment-naïve. While at inclusion the primary PAH treatment for the cohort was monotherapy (70% of patients), with 30% of the patients on combination therapy, after a median observation time of 45.3 months, the number of patients on combination therapy had increased significantly, to 50%. The use of oral anticoagulants or antiplatelets was dependent on the underlying diagnosis or comorbidities. In the entire COMPERA-CHD cohort, after follow-up and receiving targeted PAH therapy (n = 511), 91 patients died over the course of a 5-year follow up. The 5-year Kaplan-Meier survival estimate for CHD associated PH was significantly better than that for idiopathic PAH (76% vs. 54%; p < 0.001). Within the CHD associated PH group, survival estimates differed particularly depending on the underlying diagnosis and treatment status. CONCLUSIONS: In COMPERA-CHD, the overall survival of patients with CHD associated PH was dependent on the underlying diagnosis and treatment status, but was significantly better as than that for idiopathic PAH. Nevertheless, overall survival of patients with PAH due to CHD was still markedly reduced compared with survival of patients with other types of CHD, despite an increasing number of patients on PAH-targeted combination therapy.

Bronchoscopic Transparenchymal Nodule Access: Feasibility and Safety in an Endoscopic Unit.

BACKGROUND: The minimal invasive investigation of solitary pulmonary nodules becomes increasingly important with the emergence of lung cancer screening. OBJECTIVES: We report the results of the first utilization of a recently developed procedure in a bronchoscopy suite, which approaches solitary pulmonary nodules via a transparenchymal path. METHODS: This study was a prospective, single-arm interventional study. We investigated patients with a solitary pulmonary nodule detected on CT imaging, which was suspicious for malignancy. The subject's CT was employed to calculate an airway wall point of entry (POE) as well as an avascular path through lung tissue from the POE to the solitary pulmonary nodule. Using a set of catheter-based tools under fused fluoroscopy guidance, a tunnelled tract was created from the POE to the nodule. The patients were surveyed for at least 72 h in our hospital. The primary end point of the study was to evaluate the feasibility to access and biopsy solitary pulmonary nodules outside of an operation theatre. RESULTS: Six patients were recruited, and a tunnel pathway was created in 5 patients. There were no adverse events during the procedures. Two pneumothoraces were diagnosed by chest X-ray 2 h after the procedure, with one pneumothorax requiring drainage. Adequate biopsies were obtained from all 5 patients in whom a tunnel path was created. CONCLUSIONS: This study demonstrates that bronchoscopic transparenchymal access of solitary pulmonary nodules is feasible outside an operation theatre.

The Solitary Pulmonary Nodule.

Due to the high etiological diversity and the potential for malignancy, pulmonary nodules represent a clinical challenge, becoming increasingly frequent as the number of CT examinations rises. The topic gains even more importance as clear evidence for the effectiveness of CT screening was provided by the National Lung Screening Trial (NLST). Yet, the results were tempered by the high false-positive rate and the requirement of performing further diagnostic procedures. The management of those detected solitary pulmonary nodules is currently based on the individuals' risk of developing lung cancer, the pulmonary nodule characteristics and the capability of diagnostic and therapeutic approaches.

Safety and long-term efficacy of transition from sildenafil to tadalafil due to side effects in patients with pulmonary arterial hypertension.

INTRODUCTION: Two phosphodiesterase-type 5 (PDE-5) inhibitors, sildenafil and tadalafil, are approved for treatment of pulmonary arterial hypertension (PAH). It has not yet been observed if transition from sildenafil to tadalafil is beneficial in patients suffering from adverse reactions. Aim of this study was to analyze safety and long-term effects in PAH patients whose treatment was transitioned from sildenafil to tadalafil due to intolerable side-effects. METHODS: A retrospective analysis of PAH-patients who were stable on sildenafil for >3 months and transitioned to tadalafil due to adverse events was performed. Data collected included demographics, PAH-etiology, WHO-functional class, 6 min walking distance (6MWD), echocardiography, lung function tests, and NTproBNP pre-transition and 3, 6, and 12 months post-transition. RESULTS: Included were 13 PAH patients (8 females mean age 64 ± 10 years) who had been on sildenafil for a mean of 12 ± 8.4 months. In six patients (46.1 %) a switch to tadalafil was feasible and resulted in tolerable side effects and a stable clinical course with improvement of symptoms, 6MWD, stable echocardiographic findings, and NTproBNP-levels during a follow-up of 11 ± 3 months. In 5 out of 13 patients (38.5 %) adverse events occurred under tadalafil as well and therapy with PDE-5 inhibitors was discontinued. In two patients (15.4 %) sildenafil-treatment could be successfully restarted after an intermittent switch to tadalafil. CONCLUSIONS: The observations of this study indicate that a transition of sildenafil to tadalafil in case of intolerable side effects is a reasonable therapy option in about 50 % of the patients. These results should be verified by a larger prospective study.

Anxiety and depression disorders in patients with pulmonary arterial hypertension and chronic thromboembolic pulmonary hypertension.

BACKGROUND: The objective of this prospective study was to assess the prevalence of anxiety and depression disorders and their association with quality of life (QoL), clinical parameters and survival in patients with pulmonary hypertension (PH). METHODS: We prospectively assessed 158 patients invasively diagnosed with pulmonary arterial hypertension (n = 138) and inoperable chronic thromboembolic PH (n = 20) by clinical measures including quality of life (QoL, SF-36 questionnaire), cardiopulmonary exercise testing and six minute walking distance and by questionnaires for depression (PHQ-9) and anxiety (GAD-7). According to the results of the clinical examination and the questionnaires for mental disorders (MD) patients were classified into two groups, 1) with moderate to severe MD (n = 36, 22,8%), and 2) with mild or no MD (n = 122). Patients were followed for a median of 2.7 years. Investigators of QoL, SF-36 were blinded to the clinical data. RESULTS: At baseline the 2 groups did not differ in their severity of PH or exercise capacity. Patients with moderate to severe MD (group 1) had a significantly lower QoL shown in all subscales of SF-36 (p < 0.002). QoL impairment significantly correlated with the severity of depression (p < 0.001) and anxiety (p < 0.05). During follow-up period 32 patients died and 3 were lost to follow-up. There was no significant difference between groups regarding survival. Only 8% of the patients with MD received psychopharmacological treatment. CONCLUSION: Anxiety and depression were frequently diagnosed in our patients and significantly correlated with quality of life, but not with long term survival. Further prospective studies are needed to confirm the results.
