BACKGROUND: In the Korean Red Cross Blood Center, ABO blood typing are routinely performed only via red cell grouping at blood donations sites. However, when an error occurs in this process, it is impossible to issue a blood product contrary to the result of the blood type of the Blood Laboratory Center, thereby resulting in delayed supply. Therefore, efforts are needed to reduce typing errors at blood donation sites. METHODS: We analyzed 656,786 donor screenings between January 1, 2016 and December 31, 2016;we also analyzed the statistical data of donor ABO typing between 2013 and 2015. To reduce ABO typing error, we notified and trained nurses at Busan, Gyeongnam, Ulsan, and Daegu-Gyeongbuk Blood centers in June, 2016. We tried to confirm the improvement of ABO typing error at blood donation sites by comparing ABO typing before and after training. For data comparison, chi-square test was conducted (95% confidence interval, 0.05 significant level). RESULTS: The blood typing error rate was significantly lower (P=0.003) four months after training (0.005%) than before training (0.015%), and the blood typing error rate was significantly higher for the first blood donor (P<0.001). CONCLUSION: Educational training for nurses at blood donation sites may be effective in reducing ABO typing error. Continuous and regular training seems to be needed in future to reduce ABO typing error.

Objectives: This study investigated the effectiveness of the intervention program for elementary school students with reading disorders. Methods: The intervention program focused on phonological awareness, phonics, and decoding training applied individually to 25 children with a reading disorder by the teachers in charge for four months. To measure the efficacy, this study evaluated the word reading accuracy, fluency, and the related cognitive functions, including phonemic awareness, phonics, and rapid automatized naming using the Computerized Comprehensive Learning Test-Reading before and after the program. Results: After the intervention, improvements were observed in the following: the reading fluency score and fluency percentile in the word attack test; reading accuracy rate, fluency score, and fluency percentile in the nonword decoding test; fluency score and fluency percentile in the rapid automatized naming tests; accuracy rate in the letter-sound matching test; accuracy rate in the nonword repetition test. On the other hand, there was no significant difference in the paragraph reading fluency test. According to the subtypes of reading disabilities, children with dyslexic or mixed types improved after the intervention. Conclusion Reading accuracy and fluency of school-aged children with reading disorders improved through the intervention program by the schoolteachers.

Purpose: Patient handovers are critical for patient safety. Studies have shown that nurses are often interrupted during handovers, and standardized guidelines are lacking. This study aimed to develop and evaluate the effectiveness of a new handover method for emergency nurses. Methods: This quasi-experimental study implemented a new handover method from August 1, 2022, at the emergency department of a university hospital. Pre- (34 responses) and post-(16 responses, six months later) surveys and post-interviews (six participants) were conducted. In the pre-survey, data were collected regarding handover-related characteristics, cause of handover error, handover perception and handover error experience. Data regarding handover perception and handover error experience were obtained again at the post-survey. Wilcoxon’s signed rank test was used to compare handover perception and handover error experience. The interview results were analyzed using inductive content analysis. Results: There were no significant differences in information quality or interaction and support, but the new handover method was more efficient, and handover errors decreased. Four themes were identified from interview responses. Conclusion By providing a quiet place and allowing emergency nurses to independently review patient records during handovers, we expect to maintain nursing continuity, increase efficiency, and ultimately ensure patient safety and nurses’ job satisfaction.

PURPOSE: Prophylactic cranial irradiation (PCI) is a standard treatment for limited-stage small cell lung cancer (LS-SCLC) showing a response to initial treatment, but many patients do not receive PCI due to comorbidities or refusal. This study aims to define the patient group for whom PCI can be omitted with minimal risk. MATERIALS AND METHODS: Patients with LS-SCLC who underwent radiotherapy with curative aim at our institution between January 2004 and December 2015 were retrospectively reviewed. Patients who did not receive PCI were evaluated for brain metastasis-free survival (BMFS), progression-free survival (PFS), overall survival (OS), and prognostic factors for survival, and treatment outcomes were compared with a patient cohort who received PCI. RESULTS: A total of 350 patients achieved a response following thoracic radiotherapy, and 190 of these patients did not receive PCI. Stage I–II and a complete response (CR) to initial therapy were good prognostic factors for BMFS and OS on univariate analysis. Patients with both stage I–II and a CR who declined PCI showed comparable 2-year BMFS to those who received PCI (92% vs. 89%). In patients who achieved CR, PCI did not significantly improve OS or PFS. CONCLUSION: There should be less concern about omitting PCI in patients with comorbidities if they have stage I–II or a CR, with brain metastasis control being comparable to those patients who receive PCI.

OBJECTIVES: This study investigated whether adherence to the overall lifestyle recommendations in the American Cancer Society (ACS) guidelines on nutrition and physical activity for cancer survivors was associated with inflammation in breast cancer survivors. METHODS: The study included 409 women who had undergone breast cancer surgery at least 1 year before enrollment. A generalized linear model was used to estimate the least square means and 95% confidence intervals of plasma levels of inflammatory markers according to lifestyle factors defined in terms of adherence to the ACS guidelines. RESULTS: Higher overall adherence scores were associated with lower levels of high-sensitivity C-reactive protein (hs-CRP) (p for trend=0.015) and higher levels of adiponectin (p for trend=0.009). Similar significant associations of hs-CRP (p for trend= 0.004) and adiponectin (p for trend=0.010) levels were observed with the score for the body mass index (BMI) component of the adherence score. A higher diet component score was associated with a higher adiponectin level (p for trend=0.020), but there was no significant association for the physical activity component score. CONCLUSIONS The present study’s findings suggest that maintaining a healthy lifestyle according to the ACS guidelines was associated with beneficial effects on inflammatory marker levels, especially hs-CRP and adiponectin, among breast cancer survivors. Among the 3 components of lifestyle guidelines, the BMI component exhibited the most similar tendency to the overall adherence score in relation to inflammatory indicators. Further prospective and intervention studies are needed to investigate longitudinal associations between lifestyle factors and inflammatory markers among breast cancer survivors.

Background: The Arbeitsgemeinschaft für Osteosynthesefragen (AO) and the Orthopaedic Trauma Association (OTA) classification system for diaphyseal fracture has been recently revised to refine and enhance the accuracy of fracture categorization. This study aimed to investigate the interobserver reliability of the new AO/OTA classification and to compare it with the older version in femoral shaft fractures. Methods: We retrospectively analyzed 139 patients (mean age, 43.8 ± 19.5 years; 92 men and 47 women) with femoral shaft fractures who were treated from 2003 to 2017. Four well-trained observers independently classified each fracture following the previous and revised AO/OTA classification system. We calculated the Fleiss kappa for the interobserver reliability. Results: The previous classification showed the kappa value of 0.580 (95% confidence interval [CI], 0.547–0.613), and the revised version showed 0.528 (95% CI, 0.504–0.552). Both the old and the revised versions showed moderate reliability. Conclusions Our study highlights the moderate interobserver reliability of both the previous and new AO/OTA classification systems for diaphyseal femur fractures. These findings emphasize the importance of standardized systems in clinical decision-making and underscore the need for ongoing education and collaboration to enhance fracture classification.
