ObjectiveTo explore the application effect of standardized management on video-electroencephalogram (VEEG) monitoring.MethodsIn January 2018, a multidisciplinary standardized management team composed with doctors, technicians, and nurses was established. The standardized management plan for VEEG monitoring from outpatient, pre-hospital appointment, hospitalization and post-discharge follow-up was developed; the special quilt for epilepsy patients was designed and customized, braided for the patient instead of shaving head, standardized the work flow of the staff, standardized the health education of the patients and their families, and standardized the quality control of the implementation process. The standardized managemen effect carried out from January to December 2018 (after standardized managemen) was compared with the management effect from January to December 2017 (before standardized managemen).ResultsAfter standardized management, the average waiting time of patients decreased from (2.08±1.13) hours to (0.53±0.21) hours, and the average hospitalization days decreased from (6.63±2.54) days to (6.14±2.17) days. The pass rate of patient preparation increased from 63.14% to 90.09%. The capture rate of seizure onset increased from 73.37% to 97.08%. The accuracy of the record increased from 33.12% to 94.10%, the doctor’s satisfaction increased from 76.34±29.53 to 97.99±9.27, and the patient’s satisfaction increased from 90.04±18.97 to 99.03±6.51. The difference was statistically significant (P<0.05).ConclusionStandardization management is conducive to ensuring the homogeneity of clinical medical care, reducing the average waiting time and the average hospitalization days, improving the capture rate and accuracy of seizures, ensuring the quality of medical care and improving patient’s satisfaction.
The real-time monitoring of cerebral hemorrhage can reduce its disability and fatality rates greatly. On the basis of magnetic induction phase shift, we in this study used filter and amplifier hardware module, NI-PXI data-acquisition system and LabVIEW software to set up an experiment system. We used Band-pass sample method and correlation phase demodulation algorithm in the system. In order to test and evaluate the performance of the system, we carried out saline simulation experiments of brain hemorrhage. We also carried out rabbit cerebral hemorrhage experiments. The results of both saline simulation and animal experiments suggested that our monitoring system had a high phase detection precision, and it needed only about 0.030 4s to finish a single phase shift measurement, and the change of phase shift was directly proportional to the volume of saline or blood. The experimental results were consistent with theory. As a result, this system has the ability of real-time monitoring the progression of cerebral hemorrhage precisely, with many distinguished features, such as low cost, high phase detection precision, high sensitivity of response so that it has showed a good application prospect.
In order to conduct surface monitoring of the three-dimensional spine morphology of the human body in daily life, a spine morphology measuring method using "single camera, multi-view" to construct stereo vision is proposed. The images of the back of the human body with landmarks of spinous process are captured from multiple angles by moving a single camera, and based on the "Zhang Zhengyou calibration method" and the triangulation principle of binocular stereo vision, the spatial conversion matrices corresponding to each other between all images and the 3D coordinates of the landmarks are calculated. Then the spine evaluation angle used to evaluate the spine morphology is further calculated. The tests’ results showed that the spine evaluation angle error of this method is within ±3°, and the correlation between the results and the X-ray film Cobb angles is 0.871. The visual detection algorithm used in this paper is non-radioactive, and because only one camera is used in the measurement process and there is no need to pre-set the camera's shooting pose, the operation is simple. The research results of this article can be used in a mobile phone-based intelligent detection system, which will be suitable for the group survey of scoliosis in communities, schools, families and other occasions, as well as for the long-term follow-up of confirmed patients. This will provide a reference for doctors to diagnose the condition, predict the development trend of the condition, and formulate treatment plans.
ObjectiveVideo electroencephalography (VEEG) monitoring for health education of elderly patients based on a process-based communication model, and explore the impact of this model on the success rate, negative emotions, nursing satisfaction, and active cooperation rate of such patients.MethodsFrom September 2017 to September 2019, 118 patients with suspected epilepsy, encephalitis and other diseases who required VEEG monitoring in Suining Central Hospital were selected for this study (patients aged 61 to 73 years; 54 males and 64 females). Patients were divided into 2 groups using a random number table method, 59 patients in each group.A group received routine nursing, and B group received health education based on the process communication model. The monitoring success rate, negative emotion, active cooperation rate, and nursing satisfaction were compared between the two groups.ResultsThe total effective rate in the B group was 86.44%, which was significantly higher than 76.27% in the A group (P<0.05). After nursing intervention, the scores of anxiety and depression in the two groups were significantly decreased, but the decline was greater in the B group (P<0.05). The active cooperation rate and nursing satisfaction of the B group were significantly higher than those of the A group (P<0.05).ConclusionCompared with conventional nursing, health education based on process communication mode can significantly improve the success rate of VEEG monitoring in elderly patients, alleviate the negative emotions of patients, improve the active cooperation rate and nursing satisfaction.
Cardiotocography (CTG) is a non-invasive and important tool for diagnosing fetal distress during pregnancy. To meet the needs of intelligent fetal heart monitoring based on deep learning, this paper proposes a TWD-MOAL deep active learning algorithm based on the three-way decision (TWD) theory and multi-objective optimization Active Learning (MOAL). During the training process of a convolutional neural network (CNN) classification model, the algorithm incorporates the TWD theory to select high-confidence samples as pseudo-labeled samples in a fine-grained batch processing mode, meanwhile low-confidence samples annotated by obstetrics experts were also considered. The TWD-MOAL algorithm proposed in this paper was validated on a dataset of 16 355 prenatal CTG records collected by our group. Experimental results showed that the algorithm proposed in this paper achieved an accuracy of 80.63% using only 40% of the labeled samples, and in terms of various indicators, it performed better than the existing active learning algorithms under other frameworks. The study has shown that the intelligent fetal heart monitoring model based on TWD-MOAL proposed in this paper is reasonable and feasible. The algorithm significantly reduces the time and cost of labeling by obstetric experts and effectively solves the problem of data imbalance in CTG signal data in clinic, which is of great significance for assisting obstetrician in interpretations CTG signals and realizing intelligence fetal monitoring.
Objective To explore the factors associated with clinic follow-up of old patients with colorectal cancer and provide more evidence to improve the efficiency and quality of clinic follow-up after sugery. Methods The data of 253 patients who were underwent sugery because of old colorectal cancer in our hospital from January 2009 to May 2010 were reviewed. Data about the rate and times of clinic follow-up within 6 months after operation were collected via Hospital Information Systerm, then the follow-up rate was calculated, and to analyse the possible factors associated with follow-up times and rate. Results The total follow-up rate was 84.2%（213/253）, and the total times of follow-up was between 0 to 24 times per one, （4.08±0.03）times on average. On the times of follow-up, patients inside the city was higher than that outside, patients with medical or postoperative complications were higher than those without, and patients with a stoma was lower than that without, and the differences were statistically significant （P＜0.05）.While on the follow-up rate, patients underwent a radical sugery or with a stoma were lower than those not or without, and the differences were statistically significant （P＜0.05）. Conclusions The clinic follow-up of old colorectal cancer patients is not satisfactory, and the possible factors associated with follow-up times or rate are the distance between residence and hospital, have medical complications or not, have postoperative complications or not, radical sugery or not, and with a stoma or without.
There are already many ion detection methods available, and their development in long-term application practice has become very mature, which can achieve high-precision monitoring of different ion types and ion concentrations. However, in order to meet the requirements of modern smart healthcare, portable ion continuous monitoring methods with good portability, low operational difficulty, and high detection efficiency urgently need to be developed. However, existing detection methods are far from meeting the requirements of real-time and long-term health monitoring due to factors such as detection principles. In recent years, breakthroughs have been made in miniaturized and portable ion continuous monitoring technology, among which high-sensitivity and high-specificity miniature ion sensing components and miniaturized low-power driving measurement circuits have become the main research contents of this technology. This article starts with high-performance ion sensors in the front-end and high-level integrated driving measurement circuits in the back-end, summarizes the current development of miniaturized and portable ion continuous monitoring technology, reviews its applications, and looks forward to the possible development directions of portable ion monitoring technology in the future.

Objective To compare administration of incidence reporting systems for healthcare risk management in the United Kingdom, the United States, Canada, Australia, and Taiwan, and to provide evidence and recommendations for healthcare risk management policy in China. Methods We searched the official websites of the healthcare risk management agencies of the four countries and one district for laws, regulatory documents, research reports, reviews, and evaluation forms concerned with healthcare risk management and assessment. Descriptive comparative analysis was performed on relevant documents. Results (1) A total of 142 documents were included in this study. The United States had the most relevant documents (68). (2) The type of incidents from reporting systems has expanded from medication errors and hospital-acquired infections to near-misses, and now includes all patient safety incidents. (3) The incidence-reporting systems can be grouped into two models: government-led and legal/regulatory/NGO-collaborative. (4) In two cases, reporting systems were established for specific incident types: One for death or serious injury events (the sentinel events database in Britain, SIRL), and one for healthcare-associated infections (NHSN in America). (5) Compared to the four countries, Taiwan’s system put more emphasis on public welfare, confidentiality, and information sharing. The contents of reporting there covered every aspect of risk management to create a more secure environment. Conclusion (1) Britain’s national reporting and learning system was representative of a government-led model; (2) The United States was the earliest country to have a reporting system, which included a limited range of incident types. Management of incidents became more reliable with increased application of laws, regulations, and guidances; (3) Both the Canadian and the Australian systems drew from the American experience and are still developing; (4) The Taiwanese system was comprehensive and is an instructional case.
