Objective: To analyze the status of occupational medical examination (OME) institutions in Guangdong Province and the critical control points affecting their future development. Methods: A total of 211 OME institutions registered in Guangdong Province were selected as the research subjects. Their current statue was investigated, and the risk assessment of their future development was carried out based on hazard analysis and critical control point theory. Results: The OME institutions were mainly concentrated in the Pearl River Delta, accounting for 72.0%. The public and private medical and health institutions accounted for 70.6% and 29.4% respectively. The filing rates of different OME categories from high to low in the order were physical factors, chemical factors, dust, other, radiation factors, biological factors (P<0.01), and the filing rates were 89.6%, 88.6%, 84.8%, 63.0%, 7.1% and 1.0%, respectively. The rates of excellence in the field assessment from high to low in the order were hearing atlas analysis personnel, lung function examination operators, chest film reading personnel, chief examination physician, technical director, quality director (P<0.01), and the rates of excellence were 49.4%, 26.2%, 20.6%, 10.8%, 8.2% and 4.6%, respectively. A total of 37 institutions did not submit OME information, of which 23 institutions did not carry out OME work after filing. The required diagnosis rate and confirmed diagnosis rate of suspected occupational diseases in 2020 were 34.3% and 55.3%, respectively. In 2021, the detection rate of suspected occupational diseases was only 1.1‰. Among the institutions with biological monitoring records, 64.1% did not participate in external quality assessment program in laboratory, and the unqualified rate of 38 participating institutions was 55.3%. The risk assessment results show that the future development of OME institutions needs to focus on private institutions, institutions that have not reported OME information, institutions that have missed diagnosis and missed reporting of suspected occupational diseases, institutions that have not participated in external quality assessment program in laboratory and core personnel such as quality managers, technical leaders, and main inspection physicians. Conclusion: OME institutions in Guangdong Province show the characteristics of centralized filing category, centralized filing region and centralized filing institution nature. Combined with the potential risks of OME institutional capacity building, it is necessary to implement classified management, strengthen information construction, supervision and management, implement post responsibilities, and promote the high-quality development of OME institutions.

Objective To analyze the distribution features of newly reported cases of occupational welder′s pneumoconiosis (OWP) in Guangdong Province from 2013 to 2022. Methods Data of newly reported cases of OWP from National Occupational Disease Network Direct Reporting System of Guangdong Province from 2013 to 2022 was analyzed using conventional data analyzing Methods. Results A total of 294 cases of OWP were reported in Guangdong Province from 2013 to 2022 with an overall downward trend. The average age at diagnosis for new OWP cases was 44±6 years old, and the median of dust exposure duration was 11 years. Males accounted for 99.3% of the cases, and 94.2% of the cases were phase Ⅰ OWP. Guangzhou City had the highest regional distribution with 74.8% of the cases. The industry distribution was mainly manufacturing, accounting for 86.7% of the cases. The scale of enterprises was most common in small enterprises, followed by large and medium-sized enterprises, accounting for 38.4%, 30.6% and 24.5% of the cases respectively. The economic types of enterprises were mostly private enterprises, followed by state-owned enterprises, accounting for 54.1% and 32.0% of the cases respectively. Conclusion In Guangdong Province, the newly reported OWP cases were clustered in terms of disease stage, regional distribution, industry, enterprise scale and enterprise economic type. There was a tendency of younger age at diagnosis and shorter dust exposure duration.

OBJECTIVE: To evaluate the effect of clinical nursing pathway(CNP) on clinical nursing of patients with pneumoconiosis. METHODS: A total of 120 patients with pneumoconiosis were selected as the subjects by the judgment sampling method. The patients were divided into control group and observation group by random number table method, with 60 cases in each group. The patients in the control group were given routine treatment and nursing after admission, while the patients in the observation group were treated similarly to that of the control group plus CNP. The treatment of patients in both groups were carried out until they were discharged from hospital. General Self-Efficacy Scale, Medical Coping Style Questionnaire and Quality of Life Scale were used to measure the self-efficacy, coping style and of quality of life of these two groups before and after the implementation of CNP. RESULTS: Before the implementation of CNP, there was no significant difference in the scores of self-efficacy, three dimensions of coping style and four dimensions quality of life between the two groups(P>0.05). After the implementation of CNP, the scores of self-efficacy, face dimension and quality of life in the observation group were higher than those in the control group(P<0.01). The scores of surrender and avoidance dimensions decreased(P<0.01). CONCLUSION: The implementation of CNP can improve the self-efficacy, coping style and quality of life of pneumoconiosis patients.

OBJECTIVE: To explore the application effect of clinical nursing pathway( CNP) in nursing care on patients with occupational noise-induced deafness( ONID) under medical observation.METHODS: The patients with ONID under medical observation in hospital were randomly selected and divided into CNP group( 50 cases) and control group( 50 cases) by random number table method.The control group was given routine nursing care,and the CNP group was given CNP care according to the nursing path table.Self-Rating Anxiety Scale,Self-rating Depression Scale and SF-36 Scale were used to observe the anxiety, depression and quality of life of these two groups.The time and expenses of hospitalization,and degree of nursing satisfaction were also observed.RESULTS: Before nursing care implementation,the scores of anxiety,depression and 8 dimension of quality of life did not show statistical significance between these two groups( P > 0.05).After nursing care implementation,the improvement of anxiety,depression and quality of life in the CNP group were significantly better than that of the control group( P < 0.01).The patients in the CNP group had shorter duration of hospitalization( P < 0.01),decreased hospitalization expenses( P < 0.05),and increased nursing satisfaction( P < 0.01) compared with the control group.CONCLUSION: CNP implementation can effectively reduce the anxiety and depression symptoms of patient with ONID under medical observation during the diagnostic process of occupational diseases.It can reduce the time and costs of hospitalization,improve their quality of life and satisfaction of nursing care.CNP can be widely used in clinical practice.

OBJECTIVE: To investigate the effect of health education in the treatment of pneumoconiosis patients with bronchoalveoar lavage( BAL) during perioperative period. METHODS: Ninety-six pneumoconiosis patients treated with BAL in hospital were divided into observation group and control group( 48 cases in each group). The patients in the control group were given routine perioperative health education, and the patients in the observation group implemented perioperative health education in accordance with the health education pathway. Adverse reactions in hospital were collected,and the awareness of perioperative health knowledge of BAL was surveyed. RESULTS: Before implement of the health education pathway,there was no difference( P > 0. 05) in the health knowledge between the 2 groups. After implementation of the health education pathway,the awareness of health knowledge of observation group and control group were higher than that of the same group before implementation of the health education pathway( P < 0. 01). The awareness of 15 items of health knowledge was higher( P < 0. 05) and the incidences of intraoperative cough and postoperative low fever were lower in the observation group than in the control group( 4. 2% vs 25. 0%,2. 1% vs 16. 7%,P < 0. 05).CONCLUSION: Executing effective healthy education pathway in perioperative BAL is helpful to improve the knowledge of disease prevention and control in pneumoconiosis patients,and reduce the occurrence of adverse reactions during BAL.
