ABSTRACT
BackgroundWith the rapid increase in the number of COVID-19 patients in Japan, the number of patients receiving oxygen at home has also increased rapidly, and some of these patients have died. An efficient approach to identify high-risk patients with slowly progressing and rapidly worsening COVID-19, and to avoid missing the timing of therapeutic intervention will improve patient prognosis and prevent medical complications. MethodsPatients admitted to medical institutions in Japan from November 14, 2020 to April 11, 2021 and registered in the COVID-19 Registry Japan were included. Risk factors for patients with High Flow Nasal Cannula invasive respiratory management or higher were comprehensively explored using machine learning. Age-specific cohorts were created, and severity prediction was performed for the patient surge period and normal times, respectively. ResultsWe were able to obtain a model that was able to predict severe disease with a sensitivity of 57% when the specificity was set at 90% for those aged 40-59 years, and with a specificity of 50% and 43% when the sensitivity was set at 90% for those aged 60-79 years and 80 years and older, respectively. We were able to identify lactate dehydrogenase level (LDH) as an important factor in predicting the severity of illness in all age groups. DiscussionUsing machine learning, we were able to identify risk factors with high accuracy, and predict the severity of the disease. Using machine learning, we were able to identify risk factors with high accuracy, and predict the severity of the disease. We plan to develop a tool that will be useful in determining the indications for hospitalisation for patients undergoing home care and early hospitalisation.
ABSTRACT
This research was carried out to review the current state of thinga involving trainees (students and business workers) accepted by Anjo-Kosei Hospital and to clarify the role the Education Center in our hospital is expected to play in supporting trainees. The subjects were medical and non-medical students and business workers who signedup for our internship program and junior and senior high school students who paticipated in the hands-on training program at Anjo-Kosei Hospital between April 2006 and March 2009. A total of about 1,300 students and business workers had experienced the actual hands-on work each year. The number of medical students accepted was 289, 289, and 339 in 2006, 2007, and 2008, respectively. Besides, the number of non-medical students also increased from 847 to 1,045 in the period of three years. The business workers accepted came from 15 different types of occupation. It was found that junior and senior high school students were interested in the nursing-care field and this seemed to help them consider seriously their life as students and members of society, leading to the increased number of students who joined our program. In addition, unfortunately, two-fifths of the program were unfavorable for trainees because of poor management. The present research suggested that the Education Center take on a signification role in managing the internship and the hands-on training programs to accelerate the potential of students and business workers.
ABSTRACT
The main purpose of the introductory education programs designed for newly-hired employees at Anjo Kosei Hospital is to acquaint them with basic knowledge to live as members of society. In recent years, our training and development committee has been drawing up and implementing some introductory education programs about hospital regulations and philosophy for the new employees. The present study was carried out to evaluate the effects of the introductory education programs and the role played by our committee in the programs. Those who signed up for the introductory education programs were the subjects of this study. They were included composed of 154, 140, and 150 new coners in 1997, 1998, and 1999, respectively. Questionnaire surveys were conducted on them when they completed the programs. The training and development committee encouraged all of the new mployees, belonging to different occupational categories, to attend to the programs. Great emphasis who placed on education of the basic philosophy in our hospital. The surveys found that the education program about how to receive visitors was valuable to them, but they reduced education time about it clearly decreased their satisfaction level. The education program about the safety of medical treatment poorly contributed to their satisfaction even though the education time was extended. Among the programs, experience-oriented education programs, such as the in-house tour, the training of infection control, and the training of customer support, were accepted by them with enough satisfaction. These results suggested that the intervention to each program by the training and development committee is needed to satisfy the new employees by improving each program from an educational point of view.
