This paper reviewed structure and current status of laws related to patient safety using patient safety law matrix to promote systematic approach in legal system of patient safety. Laws related to patient safety can be divided into three areas: laws for preventing; laws for knowing about; and laws for responding. In the case of Korea, gaps are especially prominent in the areas of laws for knowing about and responding. Patient safety law which will be enacted in July 2016 will fill the gap in the area of laws for knowing about. This law will be comprehensive law, covering the full spectrum of laws related to patient safety. However, after reviewing current patient safety law in Korea, the following drawbacks were identified: absence of code for grasping the current patient safety level; absence of code for mandatory reporting in patient safety reporting system; and absence of code for privilege about patient safety work product. Furthermore we need wider discussions about covering issues of open disclosure, apology law, coroners system, and complaint management system in patient safety law.

Korean Journal of Ophthalmology 2020;34(5):347-352
Purpose:
To evaluate the effects of each subgroup of prostaglandin analogues (PGAs) on central corneal thickness (CCT) in patients with normal tension glaucoma (NTG).
Methods:
We retrospectively reviewed 55 eyes of 55 patients with NTG who were receiving PGA therapy. Patients who were treated with 0.005% latanoprost (16 eyes), 0.0015% tafluprost (16 eyes), or 0.004% travoprost (23 eyes) monotherapy were included. CCT assessments were performed at baseline and 1, 2, and 3 years after initiation of treatment.
Results:
In the NTG group, the mean CCT showed a decreasing trend, and there was a significant difference in mean CCT at 1, 2, and 3 years compared with baseline (baseline, 538.16 ± 32.14; 1 year, 526.55 ± 37.30 µm [p = 0.00]; 2 years, 521.67 ± 36.79 µm [p = 0.00]; 3 years, 520.43 ± 36.88 µm [p = 0.00]). The reduction of CCT was confirmed by subgroup analysis. In the 0.005% latanoprost group, mean CCT was decreased at 1 year (p = 0.11), 2 years (p = 0.00), and 3 years (p = 0.02). In the 0.0015% ta-fluprost group and the 0.004% travoprost group, mean CCT was also significantly decreased at all years (p = 0.00). No statisti-cal difference was observed between the NTG subgroups (p = 0.06).
Conclusions
Topical therapy with PGAs appeared to cause a significant decrease in CCT reduction in patients with NTG. A long-term follow-up study including more participants is needed.

Purpose:
The aim of this study was to identify factors related to the vaccination intentions of nursing students before clinical practice.
Methods:
A descriptive correlational study design was used. The participants were 129 nursing students who were enrolled in one college of nursing in Seoul and were scheduled for clinical training. Data collection was conducted from February 28 to March 7, 2022. The data were analyzed using descriptive statistics, a t-test, ANOVA, Pearson’s correlation coefficient, and a latitudinal regression analysis using the IBM SPSS statistics version 26.0 program.
Results:
The intention to vaccinate showed a significant correlation with vaccination attitude (r=.72, p<.001), subjective norms (r=.68, p<.001), and perceived behavioral control (r=.63, p<.001). The influencing factors on three intent to vaccinate were vaccination attitude (β=.36 p<.001), subjective norms (β=.31, p<.001), and perceived behavioral control (β=.36, p<.001). The explanatory power of these variables was 69.6%.
Conclusion
The vaccination rate before the clinical training of nursing students was related to economic burden, a lack of time, and transportation problems that nursing college students experienced during the vaccination process. Therefore, administrative and financial support is needed for improving the vaccination rates of nursing students.

OBJECTIVES: This study investigated the outcomes of uvula-preserving palatopharyngoplasty (UPPPP) in patients with obstructive sleep apnea syndrome (OSAS). METHODS: Twenty men with obstructive sleep apnea syndrome received the UPPPP operation at our institution. We measured symptom changes after UPPPP using a visual analog scale (VAS), and all patients were examined with polysomnography pre- and post-operatively. 'Surgical success' was defined as reduction in apnea-hypopnea index (AHI) to below 20 events per hour and more than 50% post-operative reduction. RESULTS: Snoring decreased significantly (6.7+/-2.3 to 3.7+/-2.9 on VAS, P=0.002) but the postoperative globus sense did not differ from that preoperatively (2.0+/-2.4 to 2.1+/-2.7 on VAS, P=0.79). Apnea and apnea-hypopnea indices were significantly reduced after UPPPP (34.7+/-20 to 24.2+/-17.2 events/hour, P=0.029). The surgical success rate was 40% regardless of Friedman stage. There was significant reduction in the AHI on supine sleep in both surgically successful and unsuccessful patient groups. CONCLUSION: UPPPP may minimize postoperative globus sense and other complications, with a success rate comparable to that of previously reported surgical methods in OSAS patients. In addition, it may reduce the apnea-hypopnea index in the supine sleep position.

Background:
Atopic dermatitis (AD) has been clarified that imbalance of bacterial and fungal communities in the skin and gut play key roles in immunologic dysfunction. Atopic keratoconjunctivitis (AKC), one of severe ophthalmic manifestation of AD, could be related with dysbiosis as same as AD.
Objective:
In this case-control study, the roles of conjunctival microbial communities in AKC were evaluated by a comparative analysis with healthy controls (HCs).
Methods:
16S rRNA sequencing was used to construct libraries of compositional information for a total of 30 volunteers including 20 patients with AKC and 10 HCs.
Results:
In the results, variation in the conjunctival taxonomic composition was higher in patients with AKC than in the HC group. In an analysis of relative abundance at the genus level, some taxa significantly differed between groups, including Ralstonia, Staphylococcus, Pseudomonas, Proteus, Haemophilus, and Bifidobacterium(p<0.05). Beta diversity was significantly higher in patients with AKC than in HCs (PERMANOVA, p=0.004).
Conclusion
The results indicated that the diversity and composition of the microbiome differs between patients with AKC and HCs.

Purpose:
We quantitatively analyzed the therapeutic effects of intravitreal anti-vascular endothelial growth factor (anti-VEGF) and dexamethasone implants used to treat macular edema caused by retinal vein occlusion.
Methods:
Eighty-three patients with branch retinal vein occlusion (BRVO) or central retinal vein occlusion (CRVO) with macular edema treated from February 2009 to August 2019 via anti-VEGF injections or dexamethasone implants were enrolled. The medical records of 83 eyes were retrospectively analyzed. Horizontal B-scan spectral domain optical coherence tomography images spanning the foveal center were obtained before treatment and 1 month later. These were analyzed with the aid of Image J software and the numbers of pixels corresponding to intraretinal and subretinal fluids calculated.
Results:
In patients with BRVO, the retinal fluid changes were identical 1 month after injection in both the anti-VEGF injection and the dexamethasone implant groups. For CRVO cases, the dexamethasone implant group exhibited a significantly higher loss of retinal fluid and thus a greater reduction in retinal edema than the anti-VEGF group. Linear regression analysis revealed that in BRVO cases poor final visual acuity was associated with a large amount of fluid at baseline and poor visual acuity 1 and 3 months after treatment. In CRVO cases, poor final visual acuity was associated with a large change in the intraretinal fluid level and poor visual acuity 3 months after treatment.
Conclusions
The extent of anatomical and visual acuity improvement did not differ between the anti-VEGF injection and the dexamethasone injection groups with BRVO. For CRVO patients, the short-term anatomical improvement was significantly greater in the latter group, but the extent of vision improvement was significantly higher in the former group.

BACKGROUND/OBJECTIVES:
In the Republic of Korea, “Healthy Restaurant for Sodium Reduction (HRSR)” project have been designated as one of the representative policies for sodium intake reduction. However, as of 2021, only 879 restaurants, less than 0.1% of all restaurants, had been designated. Therefore, to increase the participation of restaurants in this policy, it is necessary to examine the in-depth perception and experience of participants and non-participants in the HRSR.MATERIALS/METHODS: Two focus group discussions were conducted for HRSR project participants and non-participants.
RESULTS:
A total of 260 semantic units were derived from the 2 groups. The units were further classified into 5 upper categories and 11 subcategories. All the study participants knew the importance of low sodium intake, but they had little information on HRSR project.Various attempts have been made to encourage low sodium practice in restaurants, and the participants reported that the amount of salt used in their restaurants currently is reduced compared to that used in the past. However, they were worried about customers’ complaints about the low sodium in their diet and the insignificant beneficent associated with the policy, which makes restaurant owners reluctant to participate in this policy. All the participants agreed on the urgent need for the improvement of public awareness of low-sodium diets and for substantive government support for HRSR.
CONCLUSION
This study concluded that strategies such as more active publicity for the practice of sodium reduction in restaurants, identification of approaches to dispel the perception that low-salt diet is not tasty, and development of plans to increase the sale of food in of HRSR, are needed.

Quantitative and qualitative research explore various social phenomena using different methods. However, there has been a tendency to treat quantitative studies using complicated statistical techniques as more scientific and superior, whereas relatively few qualitative studies have been conducted in the medical and healthcare fields. This review aimed to provide a proper understanding of qualitative research. This review examined the characteristics of quantitative and qualitative research to help researchers select the appropriate qualitative research methodology. Qualitative research is applicable in following cases: (1) when an exploratory approach is required on a topic that is not well known, (2) when something cannot be explained fully with quantitative research, (3) when it is necessary to newly present a specific view on a research topic that is difficult to explain with existing views, (4) when it is inappropriate to present the rationale or theoretical proposition for designing hypotheses, as in quantitative research, and (5) when conducting research that requires detailed descriptive writing with literary expressions. Qualitative research is conducted in the following order: (1) selection of a research topic and question, (2) selection of a theoretical framework and methods, (3) literature analysis, (4) selection of the research participants and data collection methods, (5) data analysis and description of findings, and (6) research validation. This review can contribute to the more active use of qualitative research in healthcare, and the findings are expected to instill a proper understanding of qualitative research in researchers who review qualitative research reports and papers.

Background:
A methodology for comprehensively and reasonably measuring the burden of disease due to adverse events has yet to be clearly established. In this study, a new and systematic method for measuring the burden of disease due to adverse events was tested by utilizing the results of a medical record review, which is commonly used as a gold standard.
Methods:
Using the characteristics of preventable adverse events identified in the 2019 Patient Safety Incidents Inquiry (PSII), conducted to monitor the level of patient safety in Korea accurately, the resulting disability-adjusted life years (DALYs) and economic costs were estimated. DALYs were calculated as the sum of the years lived with a disability for patients who suffered permanent disability, or more, due to preventable adverse events, and the years of life lost due to premature mortality was calculated for patients who died due to preventable adverse events. The economic cost was calculated using the main diagnostic codes of patients who suffered preventable adverse events, identified as prolonged hospitalization in PSII, and the average medical cost by disease category and age group.
Results:
Estimates of DALYs due to preventable adverse events were 1,114.4 DALYs per 100,000 population for the minimum standard and 1,658.5 DALYs per 100,000 population for the maximum standard. Compared to the 2015 Korea Burden of Disease results, the ranking of DALYs due to preventable adverse events was sixth for the minimum standard and third for the maximum standard. The annual medical cost of adverse events in 2016 was estimated to be approximately Korean Republic Won (KRW) 870 billion (700 million US dollars). Medical expenses due to preventable adverse events were calculated to be approximately KRW 150 billion (120 million US dollars) as a minimum standard and approximately KRW 300 billion (240 million US dollars) as a maximum standard.
Conclusion
If this more standard method of systematically calculating the disease burden due to adverse events is used, it will be possible to compare the size of the patient safety problem with that of other diseases. The results of this study indicate that we still need to pay more attention to the issue of patient safety.
