We used a self-designed questionnaire with good reliability and validity to measure clinical nurses’ knowledge, attitudes, and practice toward catheter-related thrombosis. We used χ2 test, Welch t-test, and multiple linear regression analysis to analyze the data.Results: The knowledge of clinical nurses about catheter-related thrombosis was insufficient (55.00%), while the attitude was positive (88.49%) and the practice was inadequate (68.62%). Knowledge of clinical nurses was significantly associated with job title (β: 1.069, P< 0.001), educational level (β: 0.094, P< 0.05), and training times (β: 0.085, P< 0.05), which were positive factors while whether they are specialized nurses in intravenous therapy (β: − 0.126, P< 0.05), and hospital level (β: − 0.101, P< 0.05) were negative factors. Training times (β: 0.166, P< 0.001), job title (β: 0.099, P< 0.019), and hospital level (β: 0.090, P< 0.05) were associated factors of attitude. Moreover, training times (β: 0.255, P< 0.001) was the only factor associated with the practice.Conclusion: Although clinical nurses hold a positive attitude towards catheter-related thrombosis, their knowledge level was unsatisfactory and their practice was affected by many factors, suggesting that nursing managers should strengthen the training and skill assessment of catheter-related thrombosis. At the same time, the hospital can formulate relevant rules, regulations, and guidelines to reduce the incidence of catheter-related thrombosis.Keywords: knowledge, attitude, practice, clinical nurses, catheter-related thrombosis

At the same time, residents’ health awareness is also increasing. Implementing Internet +home care is an inevitable trend in adapting social development. Currently, Internet +home care is in the pilot stage in China, relevant institutional measures are neither standardized nor perfect, and there is no set of quality supervision indicators (QSIs).Purpose: The construction of Internet +home care QSIs in China will provide a theoretical basis for Internet +home care quality supervision.Materials and Methods: The Service-Quality model was used as the theoretical framework, and a literature review, semi-structured interviews, focus group discussions, and Delphi consultations determined the contents of the QSIs and the weight of each indicator.Results: Internet +home care QSIs were constructed and included 5 first-level indicators, 17 secondary indicators, and 69 tertiary indicators. The effective recovery rates of the two rounds of Delphi expert consultation were 100% and 85%, the expert authority coefficients were 0.810 and 0.833, and the Kendall harmony coefficients were 0.189 and 0.125 (P< 0.01). The final set of Internet +home care QSIs was as follows: tangibility (4 secondary and 16 tertiary indicators), reliability (4 secondary and 19 tertiary indicators), guarantee (5 secondary and 20 tertiary indicators), responsiveness (2 secondary and 8 tertiary indicators), and empathy (2 secondary and 6 tertiary indicators).Conclusion: The construction of Internet +home care QSIs based on the SERVQUAL model is scientifically valid, and the indicators are reliable. They provide guidance and reference values for the continuous improvement and promotion of Internet +home care. This work also provides a theoretical basis for researching and developing an Internet +home care quality supervision platform.Keywords: SERVQUAL model, Internet +home care, delphi survey, quality supervision indicator

The present study aimed to investigate nurses' willingness and demand for Internet +home care services in different levels of hospitals in China and analyze the influencing factors.From October 1 to December 31, 2021, 5714 nurses from 15 hospitals in five regions of China were recruited in this cross-sectional study using a two-stage random sampling method. A self-designed questionnaire with good reliability and validity was used to measure nurses' willingness and demand for Internet +home care services.Nurses were highly willing to provide Internet +home care services. Statistical differences were found in the willingness to provide Internet +home care services and the preference for service distance, service platform, and single service fee between nurses in different levels of hospitals (both P0.05). The willingness to provide "catheter maintenance service" and "rehabilitation nursing service" of nurses in different levels of hospitals were statistically significant (both P0.05). Nurses' demand for Internet +home care services increased with the level of their hospital. Multiple linear regression showed that professional title, educational level, monthly family income, and mortgage or car loan influence nurses' demand for Internet +home care services.Nurses' willingness and demand for Internet +home care services vary with the level of their hospitals. It is recommended that government and hospitals regulate the service items, the service distance, single service fee, and other contents according to nurses' willingness and demand and establish relevant laws and regulations to ensure the steady and orderly development of the Internet +home care services.
