Objective To explore the influencing factors of inhalation medication compliance in Chinese asthma patients, and to provide evidence for improving the compliance of patients with inhalation therapy. Methods PubMed, China National Knowledge Infrastructure, Wanfang, Chongqing VIP, and SinoMed were searched for literature on factors influencing inhalation medication compliance in Chinese asthma patients from the establishment of databases to December 2021. Meta-analysis was performed using RevMan 5.2 software. Results A total of 16 studies were included, with a sample size of 2 600 cases, 1 084 cases of good compliance with inhalation administration, 1 516 cases of poor compliance with inhalation administration, and good compliance with inhalation administration accounted for 41.69%. The literature quality evaluation scores were all ≥4 points, all of which were of medium quality and above. Meta-analysis showed that the factors affecting inhalation compliance of asthma patients included age [odds ratio (OR)=0.54, 95% confidence interval (CI) (0.32, 0.91), P=0.02], educational level [OR=0.57, 95%CI (0.36, 0.90), P=0.02], doctor-patient relationship [OR=0.42, 95%CI (0.19, 0.93), P=0.03], disease severity [OR=0.25, 95%CI (0.11, 0.58), P=0.001], degree of mastery of asthma knowledge [OR=2.51, 95%CI (1.11, 5.65), P=0.03], degree of mastery of inhalation technique [OR=8.66, 95%CI (3.20, 23.40), P<0.0001], adverse drug reaction [OR=0.23, 95%CI (0.13, 0.41), P<0.00001]. Conclusion The compliance of inhaled dosing in Chinese asthma patients needs to be improved urgently. Age, education level, doctor-patient relationship, disease severity, mastery of asthma knowledge, mastery of inhalation technology, and adverse drug reactions are the important influencing factors of inhaled medication compliance.
ObjectiveTo investigate the clinical features and prognosis of fibrinous mediastinum and evaluate the value of different examinations in diagnosis and evaluation. MethodsTwenty-eight patients with mediastinal fibrosis diagnosed between January 2015 and September 2020 in China-Japan Friendship Hospital were studied retrospectively. The Clinical manifestations, radiological characteristics, endoscopic features, echocardiography, V/Q SPECT, cardiac catheterization, treatment and prognosis were analyzed.ResultsThe main clinical symptoms were cough (77.6%), expectoration (57.1%), wheezing or suffocating (42.9%), dyspnea (39.3%). There were 67.9% of the cases who were considered previous or present tuberculosis. Imaging findings showed that the fat density in the mediastinum disappeared, the irregular soft tissue of the mediastinum surrounded the airway and pulmonary vessels, and many lymph nodes enlarged and calcified, and multiple bronchus and pulmonary vessels were compressed and narrowed. Pulmonary function was mainly manifested as obstructive ventilate dysfunction and decreased diffusion volume. Under bronchoscopy, the bronchial mucosa showed pigmentation, bronchial distortion or multiple stenosis, even occlusion, and bronchial mucosa edema or congestion. Echocardiography and catheterization of the right heart showed that pulmonary hypertension and diastolic cardiac dysfunction were common complications of fibrillary mediastinum. Pulmonary ventilation perfusion imaging showed impaired blood perfusion in 87.5% of patients and impaired ventilation perfusion in 37.5% of patients. The symptoms of some patients alleviated after anti-infective and symptomatic treatment, but the mediastinal fibrosis was irreversible, and the efficacy of anti-tuberculosis and glucocorticoid therapy was limited. ConclusionsFor patients with clinical consideration of fibrous mediastinum, chest enhanced CT should be performed for clear diagnosis. Relevant examinations, such as pulmonary function, endoscopic, echocardiography, should be conducted to evaluate whether the disease involves airway, pulmonary vessels, pericardium, superior vena cava and esophagus, as well as the degree of functional involvement. Attention should be paid to the evaluation of patients with pulmonary hypertension and diastolic cardiac insufficiency.
