Background: Respiratory infections play a major role in acute exacerbation of chronic obstructive pulmonary disease (AECOPD). This study assessed the prevalence of bacterial and viral pathogens and their clinical impact on patients with AECOPD. Methods: This retrospective study included 1,186 patients diagnosed with AECOPD at 28 hospitals in South Korea between 2015 and 2018. We evaluated the identification rates of pathogens, basic patient characteristics, clinical features, and the factors associated with infections by potentially drug-resistant (PDR) pathogens using various microbiological tests. Results: Bacteria, viruses, and both were detected in 262 (22.1%), 265 (22.5%), and 129 (10.9%) of patients, respectively. The most common pathogens included Pseudomonas aeruginosa (17.8%), Mycoplasma pneumoniae (11.2%), Streptococcus pneumoniae (9.0%), influenza A virus (19.0%), rhinovirus (15.8%), and respiratory syncytial virus (6.4%). Notably, a history of pulmonary tuberculosis (odds ratio [OR], 1.66; p=0.046), bronchiectasis (OR, 1.99; p=0.032), and the use of a triple inhaler regimen within the past 6 months (OR, 2.04; p=0.005) were identified as significant factors associated with infection by PDR pathogens. Moreover, patients infected with PDR pathogens exhibited extended hospital stays (15.9 days vs. 12.4 days, p=0.018) and higher intensive care unit admission rates (15.9% vs. 9.5%, p=0.030). Conclusion This study demonstrates that a variety of pathogens are involved in episodes of AECOPD. Nevertheless, additional research is required to confirm their role in the onset and progression of AECOPD.

Purpose: This study aimed to improve the reimbursement policies in the service of Korean Advanced Practice Nurses (APNs) to enhance their utilization in practice. Methods: The study was conducted in three stages: 1) reviewing other countries’ APN systems; 2) conducting focus group interviews and online surveys with APNs to gather opinions on their roles, practices, and reimbursement status; and 3) proposal for improving reimbursement policies based on expert consultations. The data was collected between March and June 2023. Results: In the United States, APNs can be reimbursed at 85~100 % of physician fees for services provided under the Balanced Budget Act of 1997. In Japan, reimbursement is only available for 38 tasks performed among specially trained Certified Nurses. Master’s level APN education has been created but not nationally legislated. The results of focus group interviews reveal low awareness and legal limitations of Korean APNs’ roles. The results of online surveys indicate high professional pride but low satisfaction with little reimbursement system, and 71.4% of respondents denote the APN field’s integration. Also, expansion of current reimbursement to other APN fields and regular evaluation of roles and reimbursement were recommended. Conclusion In this study, it is necessary to clarify APNs’ roles, and scope of practice, and establish benefits and reimbursement systems for professional APNs’ health services. This study suggests improvements to enhance the Korean APN system and healthcare quality in Korea.

Purpose: The management of bowel bladder disorder (BBD) has only been indicated for subjective constipation without objective evidence. We attempted to highlight the radiological findings in patients with BBD and construct a scoring system to identify patients with BBD prior to treatment. Materials and Methods: Forty-five patients with lower urinary tract dysfunction (LUTD) received polyethylene glycol for 2 months before bladder medication for LUTD. Based on partial response to LUTD following treatment, we divided the patients into LUTD-fecal impaction (FI) and LUTD not attributed to FI (LUTD-NFI) groups. Pre/post-treatment kidney, ureter, and bladder (KUB) were compared with respect to several radiographic parameters. Items with significant changes after treatment were included in the scoring system. The accuracy and inter-rater agreement were also evaluated. Results: Cecal dilation, descending colon dilation, fecal quality, and overall haziness were found to undergo significant changes after laxative treatment. We assigned 0 to 2 points for each item, with a total score of 8. Receiver operating characteristic curve analysis revealed a cutoff value of 5 between LUTD-FI and LUTD-NFI, with 79% sensitivity and 88% specificity. The scoring system was instructed to six doctors who were unaware of it and was then tested on previous patients, which showed a substantial concordance rate (κ=0.79, p<0.05). Conclusions Fecal scoring system based on KUB was beneficial in identifying children with LUTD attributed to FI. This may provide an opportunity to obtain objective FI data as an alternative to subjective assessment of constipation.
