ABSTRACT
Objective To investigate awareness of definition, diagnostic criteria, severity classification and standard diagnosis and treatment for chronic obstructive pulmonary disease (COPD) among primary-care physicians at the grassroots in urban and suburban Shanghai.Methods In total, 298 physicians were surveyed by unified questionnaire for COPD-related knowledge in two secondary-care general hospitals (one in urban and suburban areas each ) and 12 community primary-care centers (four in urban and eight in suburban areas) in Shanghai.One hundred and fifteen physicians in two urban hospitals and one suburban hospital were trained professionally and then evaluated for its effectiveness.Results Awareness of diagnostic criteria of COPD was only 22.4% (35/156), 25.6% ( 10/39), 4.3 % (3/69)and 26.5% (9/34) among physicians in urban primary-care hospitals, urban secondary-care hospitals,suburban primary-care hospitals and suburban secondary-care hospitals, respectively.Their awareness of knowledge about use of anti-cholinergic agents was 13.5 % (21/156), 35.9 % ( 14/39), naught (0/69),and 14.7 % ( 5/34 ), respectively.Only 0.67 % of them ( 2/298 ) knew about severity classification of COPD.Awareness of definition and diagnostic criteria for COPD in the physicians increased to 72.2 % ( 83/115) after training from 18.2% (21/115) before it, and their awareness of severity classification for COPD increased to 45.2% (52/115) after training from 0.8 % (1/115) before it.Conclusions Awareness of COPD-related knowledge, especially of standard diagnosis and treatment for COPD, was poor in primary-care physicians at the grassroots in Shanghai, so it is necessary to strengthen training for them in COPD-related knowledge, including pulmonary function tests.
ABSTRACT
Objective To investigate the influences of Bi-level positive airway pressure(BiPAP)to night-time hy- poxemia and change of sleep structure in the patients with overlap syndrome(OS).Methods 25 patients with OS,19 with primary snoring(PS)were monitored and diagnosed by nocturnal polysomnography(PSG)for parameters of sleep efficiency(SE)and sleep architecture.The data of patients with OS were rechecked after 2-month's BiPAP treatment. Results In OS group,the level of FEV1%,FEV1/FVC,SaO2 A,SaO2 L,SE,REM and S3+4 were significantly lower than those in PS(P
ABSTRACT
Objective To investigate sleep efficiency and characteristics in pediatric obstructive sleep apnea hypopnea syndrome (OSAHS) and primary snoring (PS) children. Methods 32 children with OSAHS, and 27 PS children were monitored by nocturnal polysomnography (PSG). The parameters of sleep efficiency(SE) and sleep composition, including apnea/hyponea index(AHI),stageⅠ sleep(S1)%, stageⅡ sleep(S2)%, slow wave sleep(SWS)% and rapid eye movement(REM)%, were recorded and compared between the two groups. Results In OSAHS group,the SE was significantly lower than that in PS group (P
