Evaluation of an ultrasound program in nationwide Continuing Professional Development (CPD) in Korean public health and medical institutions.

BACKGROUND: The Education and Training Centre for Public Healthcare of the National Medical Centre plays a key role in providing continuing professional development (CPD) to 221 public health and medical institutions in South Korea. To assess the realization of the Centre's core value and the intended changes, program evaluations are required. The context, input, process, and product (CIPP) model is particularly suitable for evaluating CPD in the public sector, as it allows for recognizing the dynamic nature of the program environment. METHODS: This research applied the CIPP model to the evaluation of CPD programs, particularly abdominal and thoracic ultrasound programs implemented in 2017 and 2018. Data were collected from 2017 to 2019. The program and its feedback were reviewed in the context evaluation. Based on this, a subsequent program strategy was established for the input evaluation. Observing the program in real time and recording its progress was followed in process evaluation. Finally, the outcomes and impacts of the program were reviewed and compared with baseline data in the product evaluation. RESULTS: In context evaluation, the educational needs of the Centre's CPD program recipients, impediments that inhibit participation in education, and resources that the Centre can utilize were identified through an online survey, focus group interviews and expert consultation. Through input evaluation, we identified the best alternative that satisfied all pre-selected criteria, which were responsiveness to priority system needs, potential effectiveness, fit with existing services, affordability, and administrative feasibility. Observing the program in real time and recording its progress were conducted in process evaluation, demonstrating that the augmented program went as planned, and even had to be expanded due to increased demand. The impact of the program was measured, interpreted, and assessed in the product evaluation. The review committee decided that the intended change had been occurred, thus the Centre decided to maintain the program. CONCLUSION: A thorough evaluation is necessary to determine the potential benefits of CPD. The CIPP methodology is valuable for executing formative and summative evaluations. The CIPP model is particularly useful for securing accountability data for large-scale nationwide educational programs supplied by public funds.

Protocol for the first clinical trial to investigate safety and efficacy of corneal xenotransplantation in patients with corneal opacity, corneal perforation, or impending corneal perforation.

BACKGROUND: Xenotransplantation using fresh porcine corneas has been suggested as a feasible alternative to overcome the shortage of human donor corneas. Successful long-term survival of grafts without evidence of xenozoonosis in clinically applicable pig-to-non-human primate corneal transplantation model has brought researchers close to human clinical trials. Accordingly, we aimed to prepare a clinical trial protocol to conduct the first corneal xenotransplantation. METHODS: We developed the clinical trial protocol based on international consensus statement on conditions for undertaking clinical trials of corneal xenotransplantation developed by the International Xenotransplantation Society. Detailed contents of the protocol have been modified with reference to comments provided by ophthalmologists and multidisciplinary experts, including an infectionist, an organ transplantation specialist, a clinical pharmacologist, a neuropsychiatrist, a laboratory medicine doctor, and a microbiologist. RESULTS: Two patients with bilateral legal corneal blindness (best-corrected visual acuity ≤20/200 in the better eye and ≤20/1000 in the candidate eye) or with (impending) corneal perforation will be enrolled. During the screening period, participants and their family members will have two separate deep consideration periods before signing informed consent forms. Each patient will undergo corneal xenotransplantation using fresh corneas from Seoul National University miniature pigs. Commercially available immunosuppressants will be administered and systemic infection prophylaxis will be performed according to the program schedule. After transplantation, each patient will be monitored at a specialized clinic to investigate safety up to 2 years and efficacy up to 1 year. CONCLUSIONS: A detailed clinical trial protocol for the first corneal xenotransplantation reflecting the global guidelines is provided.

Korean attitudes to Xenotransplantation: a survey conducted in 2009.

BACKGROUND: Xenotransplantation research has been being actively conducted in Korea. However, there are numbers of socio-ethical issues involved in this research, and it is necessary to know public attitudes toward the research, inducing "public consensus" for the sound development of the technology. MATERIALS AND METHODS: A telephone survey consisting of 10 questionnaire items was conducted to investigate the attitudes of Koreans on social and ethical issues related to xenotransplantation. Participants were randomly selected in proportion to the 2009 Korean population census. The response rate was 22.3%. Finally, 500 sets of data were collected and analyzed with SPSS® 12. A statistical analysis was performed using the chi-square test. RESULTS: In the first phase of the study, 69.8% of the respondents were positive about xenotransplantation while 29.0% were negative. However, after being informed of the specific benefit and risk, 58.4% of the respondents stated that xenotransplantation research should be continued, while 38.6% of them indicated that these studies should be prohibited; 63.0% of the respondents agreed with lifelong surveillance after xenotransplantation, while 34.0% disagreed. To avoid triggering immune response in the transplantees, 63.0% of the respondents also approved of the necessity of genetic modification of pigs. If xenotransplantation proves to be safe, 56.8% of the respondents said that they would accept it if necessary; 69.8% of the respondents would recommend it for their family members and friends as a therapeutic option if they are in need. Men were more positive than women about the necessity of animal experimentation for xenotransplantation research, the necessity of lifelong surveillance, and the necessity of genetic modification of pigs. There was no significant difference between the religious and non-religious group except about the issue of lifelong surveillance. CONCLUSION: Korean people have relatively positive attitudes toward xenotransplantation research and animal experiments regarding xenotransplantation.
