Analyzing the barriers and enablers to internet hospital implementation: a qualitative study of a tertiary hospital using TDF and COM-B framework.

Background: Internet hospitals have become an important way to improve the accessibility of medical services and promote medical equity in China. However, there is still lack of research on the behavior of medical personnel during the process of using Internet medical services, and the elements of behavior that motivate doctors to actively use or resist the use of Internet hospitals are still not fully analyzed. The study applied the Theoretical Domains Framework to examine the factors affecting the engagement of medical personnel in Internet hospitals, with the aim of guiding the design of intervention to enhance Internet hospital participation. Methods: This study utilized qualitative analysis. Semi-structured questionnaires based on the Theoretical Domains Framework (TDF) and Capability-Opportunity-Motivation-Behavior (COM-B) model was developed and administered to 40 doctors and nurses at a Grade A tertiary hospital in Guangdong Province. Data was coded and analyzed using qualitative methods including Nvivo software. Results: The research displayed 19 barriers and 7 enablers for the implementation of Internet hospitals, all 14 TDF domains impacted participation with motivation cited most frequently. Despite challenges, medical personnel exhibited a generally optimistic stance towards utilization of the Internet hospital. Major barriers include the higher requirement of diagnostic ability, objective difficulties brought by online consultation to the decision-making process, limitation of time and other resources, not ideal technological and institutional environment, lack of self-efficacy and negative expectation of results in online consultation. Key enablers include patient needs and the positive impact of online care on the medical process and patient experience. Discussion: This qualitative study identified a range of barriers and enablers to Internet hospital participation according to medical personnel, providing an conceptual framework to guide further research evaluating implementation strategies. Expanded research and targeted interventions design can help optimize participation in this evolving healthcare delivery model.

In situ Preparation of HNbMoO6/C Nanocomposite for Sensitive Detection of Clenbuterol.

In this paper, we synthesized HNbMoO6/C composite through the calcination of octylamine-intercalated HNbMoO6 precursor. The resulting HNbMoO6/C composite showed some new phases of MoO2, MoO3, NbO2, Nb2O5, and carbon, which was fully confirmed via powder X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), selected area electron diffraction (SAED), and X-ray photoelectron spectroscopy (XPS) technologies. Besides, the HNbMoO6/C hybrid was coated on glass carbon electrode to construct an electrochemical sensor for sensitive determination of clenbuterol. The electrochemical behaviors of clenbuterol on the prepared electrode were tested by cyclic voltammetry (CV) and differential pulse voltammetry (DPV) analysis. The results showed that the intercalated carbon can act as active sites to accelerate electron transfer. In addition, more exposed surface areas of the HNbMoO6/C composite will facilitate the electrolyte to permeate. The oxidation peak current of clenbuterol was linearly related to its concentration in the range of 1.04 × 10-5 to 7.51 × 10-4 mol L-1, and the determination limit was calculated to be 3.03 × 10-6 mol L-1 (S/N = 3). This sensor exhibits excellent stability, reproducibility, specificity, and good recoveries when applied to monitor clenbuterol in real samples.

Fabrication of a New Self-assembly Compound of CsTi2NbO7 with Cationic Cobalt Porphyrin Utilized as an Ascorbic Acid Sensor.

A novel sandwich-structured nanocomposite based on Ti2NbO7- nanosheets and cobalt porphyrin (CoTMPyP) was fabricated through electrostatic interaction, in which CoTMPyP has been successfully inserted into the lamellar spacing of layered titanoniobate. The resultant Ti2NbO7/CoTMPyP nanocomposite was characterized by XRD, SEM, TEM, EDS, FT-IR, and UV-vis. It is demonstrated that the intercalated CoTMPyP molecules were found to be tilted approximately 63° against Ti2NbO7- layers. The glass carbon electrode (GCE) modified by Ti2NbO7/CoTMPyP film showed a fine diffusion-controlled electrochemical redox process. Furthermore, the Ti2NbO7/CoTMPyP-modified electrode exhibited excellent electrocatalytic oxidation activity of ascorbic acid (AA). Differential pulse voltammetric studies demonstrated that the intercalated nanocomposite detects AA linearly over a concentration range of 4.99 × 10-5 to 9.95 × 10-4 mol L-1 with a detection limit of 3.1 × 10-5 mol L-1 at a signal-to-noise ratio of 3.0.
