PURPOSE: Childhood asthma has a considerable social impact and economic burden, especially in severe asthma. This study aimed to identify the proportion of childhood asthma severity and to evaluate associated factors for greater asthma severity. METHODS: This study was performed on 667 children aged 5–15 years with asthma from the nationwide 19 hospitals in the Korean childhood Asthma Study (KAS). Asthma was classified as mild intermittent, mild persistent, and moderate/severe persistent groups according to the National Asthma Education and Prevention Program recommendations. Multinomial logistic regression models were used to identify the associated factors for greater asthma severity. RESULTS: Mild persistent asthma was most prevalent (39.0%), followed by mild intermittent (37.6%), moderate persistent (22.8%), and severe persistent asthma (0.6%). Onset later than 6 years of age (adjusted odds ratio [aOR], 1.69 for mild persistent asthma; aOR, 1.92 for moderate/severe persistent asthma) tended to increase asthma severity. Exposure to environmental tobacco smoke (aOR, 1.53 for mild persistent asthma; aOR, 1.85 for moderate/severe persistent asthma), and current dog ownership with sensitization to dog dander (aOR, 5.86 for mild persistent asthma; aOR, 6.90 for moderate/severe persistent asthma) showed increasing trends with greater asthma severity. Lower maternal education levels (aOR, 2.32) and no usage of an air purifier in exposure to high levels of outdoor air pollution (aOR, 1.76) were associated with moderate/severe persistent asthma. CONCLUSIONS: Modification of identified environmental factors associated with greater asthma severity might help better control childhood asthma, thereby reducing the disease burden due to childhood asthma.

PURPOSE: Data are lacking on the association between the allergic rhinitis (AR) phenotype and sensitization to specific allergens or bronchial hyperresponsiveness (BHR) in children. We here investigated risk factors and comorbidities, including sensitization to specific allergens and BHR, for the AR phenotype by AR and its Impact on Asthma (ARIA) classification in a general population-based birth cohort study. METHODS: We enrolled 606 children aged 7 years from the Panel Study of Korean Children. The AR phenotype was assigned in accordance with the ARIA classification in children. Skin prick tests and Provocholine provocation test were performed. Risk factors and comorbidities for AR phenotypes were then analyzed. RESULTS: The prevalence of mild and moderate to severe AR in our study cohort was 37.2% and 8.8%, respectively. Recent use of analgesics or antipyretics and current cat ownership were associated with the risk of mild persistent AR. Sensitizations to Dermatophagoides Pteronyssinus (Der p), Japanese hop and cat were associated with moderate to severe persistent AR. Children with moderate to severe AR had a higher risk of current asthma and BHR compared to mild AR cases (adjusted odds ratio [aOR], 5.26; 95% confidence interval [CI], 1.77–15.62). Moderate to severe AR with allergic sensitization was associated with the highest risk of BHR (aOR, 11.77; 95% CI, 3.40–40.74). CONCLUSIONS: Moderate to severe-persistent AR is more closely related to respiratory comorbidities and sensitizations than mild AR. Stratifying the AR phenotype by ARIA classification may assist in disease management.

PURPOSE: Successful application experiences on public-private partnership (PPP) in different countries, suggest that PPP could be an option in road traffic injury (RTI) prevention. The present study aims at investigating the applicability of PPP policy in RTI prevention in Iran based on the experts' perspectives. METHODS: This is a qualitative study with grounded theory approach which has been conducted in Tabriz University of Medical Sciences, Iran in 2018. The participants were 22 experts in the field of RTIs selected using purposive sampling method. Data were collected by semi-structured interviews and analyzed with content-analysis method. RESULTS: The results were classified under 5 main themes (applicability, scopes and services, challenges, advantages, and strategies) for applying PPP policy and 37 sub-themes. Due to the prevalence of RTIs, the present challenges in public sector, existence of qualified private sector, and successful experiences in other areas, there are opportunities for private sector partnership in prevention of RTIs. Private sector could participate in different scopes and services regarding RTI prevention, including road construction and maintenance, maintenance and provision of vehicles safety and public education. The main challenges including legislation issues, ambiguities in collaboration, political and organizational unsustainability, government's financial hardship and lack of experienced experts in the field of RTI. However, there are significant advantages including high efficiency in program implementation, covering the weaknesses of public sector, effective and efficient management on application of PPP in RTI prevention. The strategies include identifying and prioritizing the assignable activities, identifying the qualified private sector, developing PPP policies and legal frameworks, creating a common language between public and private parties, trying to meet the expectations of the private sector by public sector, developing a comprehensive and sound contract, and cultivating public culture to accept private sector in the field of RTI prevention. CONCLUSION This study sought to determine whether PPP could be used as strategy to reduce the burden of RTIs in Iran. But it requires a lot of preliminary studies to provide the context and conditions for applying this policy.

Background: Through the years of improving quality health service delivery, hospital bed capacity in the Philippines has remained to be a persistent challenge. In light of the aim of the Universal Health Care Act to protect and promote the right to health of every Filipino, one metric used to identify areas that are in most need or are under served, is the number of public hospital beds vis a vis the catchment population. Methods: The systematic review of literature was utilized to generate a policy brief presented to the invited stakeholders of the policy issue for the roundtable discussion participated by all key stakeholders of the policy issue. Evidence and insights were thematically analyzed to generate consensus policy recommendations. Results: With the current hospital bed availability and maldistribution, the Philippines still faces compounded issues in addressing healthcare demands. Currently, the request for increasing bed capacity is done through legislation. In context, this request is also parallel in expanding service capacity through the allocation of more funds and personnel. The ratio of private and charity beds must ensure to have equity among all patients of varying segments of the population. Enjoining private hospitals to share bed capacity for public service was also explored given appropriate subsidies. Conclusion and Recommendation To ensure equity in health service delivery, it is imperative to assess, strategize, and conduct prioritization of the needs of government hospitals for increased bed capacity, considering the distribution, socio-demographic profile, and health needs of the catchment population.

BACKGROUND: Epidemic thunderstorm asthma (ETSA) severely affected Melbourne, Australia in November 2016. There is scant literature on the natural history of individuals affected by ETSA. OBJECTIVE: A multicentre 12-month prospective observational study was conducted assessing symptomatology and behaviors of ETSA-affected individuals. METHODS: We used a structured phone questionnaire to assess asthma symptom frequency, inhaled preventer use, asthma action plan ownership and healthcare utilization over 12 months since the ETSA. Analysis of results included subgroup analyses of the “current,” “past,” “probable,“ and “no asthma” subgroups defined according to their original 2016 survey responses. RESULTS: Four hundred forty-two questionnaires were analyzed. Eighty percent of individuals reported ongoing asthma symptoms at follow-up, of which 28% were affected by asthma symptoms at least once a week. Risk of persistent asthma symptoms was significantly higher in those with prior asthma diagnosis, current asthma, and probable undiagnosed asthma (all p < 0.01). Of 442 respondents, 53% were prescribed inhaled preventers, of which 51% were adherent at least 5 days a week. Forty-two percent had a written asthma action plan and 16% had sought urgent medical attention for asthma in the preceding year. CONCLUSIONS: Following an episode of ETSA, patients experience a pivotal change in asthma trajectory with both loss of asthma control and persistence of de novo asthma. Suboptimal rates of inhaled preventer adherence and asthma action plan ownership may contribute to asthma exacerbation risk and susceptibility to future ETSA episodes. Longer-term follow-up is needed to determine the extent and severity of this apparent change.

OBJECTIVES: Conventional radiological processes have been replaced by digital images and information technology systems within South Africa and other developing countries. Picture Archiving and Communication Systems (PACS) technology offers many benefits to institutions, medical personnel and patients; however, the implementation of such systems can be a challenging task. It has been documented that South Africa has been using PACS for more than a decade in public hospitals with moderate success. The aim of this study was to identify and describe the PACS challenges endured by PACS vendors during implementation in the South African public healthcare sector. METHODS: This was achieved by engaging in a methodological approach that was qualitative in nature collecting data through semi structured interviews from 10 PACS experts/participants which were later analysed qualitatively. RESULTS: The findings show that PACS vendors have countless challenges, some of which include space, insufficient infrastructure, image storage capacity, system maturity and vendor related concerns. It was clear that the PACS experts readily offered contextually appropriate descriptions of their encounters during PACS implementations in South African public healthcare institutions. CONCLUSIONS: PACS vendors anticipate these challenges when facing a public healthcare institution and it is recommended that the hospital management and potential PACS stakeholders be made aware of these challenges to mitigate their effects and aid in a successful implementation.

BACKGROUND: Children today are exposed to various media devices, and their usage of these is increasing. Prior studies have outlined forms of harm this can potentially cause. However, there has been little empirical research on the use of media devices among preschool children in Asia. The aim of this study was to examine and analyze longitudinal trends in media device use among Korean preschool children, focusing on the frequency of engagement, time spent with, and ownership of media devices, delineated by sex. METHODS: Four hundred parents of children aged 2–5 years were invited to enroll. The baseline assessment, Wave 1, was conducted between December 2015 and June 2016, and follow-up assessments, Wave 2 and Wave 3, were conducted annually for the following 2 years. Time of media use, frequency of media use, and ownership of media devices (TV, tablet PCs, and smartphones) were investigated. RESULTS: Ownership of tablet PCs increased significantly between Wave 1 and Wave 3 for boys and girls (corrected P < 0.001). Frequency of media use increased significantly between Wave 1 and Wave 3 only in boys' use of tablet PCs (mean difference 0.8 day/wk). Time of media use increased significantly between Wave 1 and Wave 3 for both sexes in all devices, measured by mean difference on weekdays and weekends (TV by 0.6 and 0.7 hr/day, tablet PCs by 0.6 and 0.8 hr/day, and smartphones by 0.4 and 0.4 hr/day). Children spent more time using media devices during weekends than on weekdays. CONCLUSION: This study observed an increase in the tendency of media device use among preschool children in Korea. The patterns of use indicate that paying attention to the types of devices children use is needed, as well as vigilance on weekends.

Rapid and correct diagnosis is essential for national tuberculosis (TB) control. A greater national concern for quality control (QC) of Mycobacterium tuberculosis (MTB) testing is required to improve the proficiency of domestic clinical laboratories using diverse testing protocols in private and public sectors. External quality assessment (EQA) is an important program accompanying internal QC in clinical TB laboratories. In Korea, the EQA program initiated in 2005 by the Korean Association of External Quality Assessment Service (KEQAS) has made remarkable progress in the harmonization of private and public sectors with governmental support since 2011. An integrative TB EQA program led by the KEQAS with financial support from the Korea Centers for Disease Control and Prevention provides optimized EQA materials for both public and private sectors. In 2017, the KEQAS implemented ‘The Next-Generation Proficiency Testing Program’ equipped with a centralized control system of QC material production and electronic data management, which increased the scale of operating programs from 46 to 54 and recruited 1,700 participants. The TB program was also expanded to provide three times EQA for private laboratories from 2 times a year. For TB EQA programs implemented via the Clinical Microbiology Subcommittee of the KEQAS, survey materials were distributed by sectional orders for tests such as acid-fast bacilli (AFB) smears, AFB culturing and identification, antituberculous drug susceptibility screening, AFB molecular diagnosis, and rapid detection of rifampin and isoniazid resistance. All survey materials were produced by sophisticated manufacturing processes and thoroughly analyzed by various commercial kits, targeted DNA sequencing, and whole-genome sequencing in pre- and post-manufacturing phases for advancement in the EQA program.

PURPOSE: It is controversial whether indoor pet exposure is either a risk or protective factor developing sensitization to pet allergens or asthma. Therefore, we investigated whether indoor pet ownership entails a risk for the development of asthma and sensitization in childhood. METHODS: The Panel Study of Korean Children (PSKC) is a general-population-based birth cohort study that recruited 2,078 mother-baby dyads in Korea between April and July of 2008. Among 1,577 children who were followed up in 2015, 559 underwent skin prick tests, spirometry and bronchial provocation tests using Provocholine. Having a cat or a dog and the prevalence of asthma were evaluated by using self-reported questionnaires and physicians’ medical records. RESULTS: During infancy, the rate of dog ownership was 4.5% (71 of 1,574) and that of cat ownership was 0.5% (8 of 1,574). Of the subjects, 7.9% (n=109) currently had at least 1 dog and 2.5% (n=34) had at least 1 cat. Pet ownership during infancy was associated with sensitization to cats or dogs (adjusted odds ratio [aOR], 4.24; 95% confidence interval [CI], 1.29–13.98), wheezing within 12 months (aOR, 5.56; 95% CI, 1.65–18.75) and current asthma (wheezing episode in the last 12 months+diagnosed asthma by physicians) (aOR, 6.36; 95% CI, 1.54–26.28). In contrast, pet ownership during the last 12 months was not associated with sensitization to cats or dogs or current asthma. CONCLUSION: Indoor pet exposure during infancy can be critical for developing sensitization to cats or dogs and asthma in childhood. Avoidance of pet exposure in early life may reduce sensitization to cats or dogs and development of asthma.

The first hospice care center in Korea dates back to the East West Infirmaries (Dongseodaebiwon in the Korean language) of the Goryeo period in the early 11th century. It has been 50 years since hospice care was introduced in Korea. Initially hospice care was provided in the private sector, including those with a religious background, and its development was slow. In the 1990s, related religious organizations and academic associations were established, and then, a full-swing growth phase was ushered in as the Korean government institutionalized hospice care in the early 2000s. As a result, enhanced quality of hospice care service could be provided, which meant better pain management and higher quality of life for late stage cancer patients and their families. Still, the nation lacked a realistic reimbursement system which was needed to for financial stability of the affected patients. However, the national health insurance scheme began to cover hospice palliative expenses in 2015. In 2016, the Act on Decisions on Life-Sustaining Treatment for Patients in Hospice and Palliative Care or at the End of Life was legislated, allowing terminally-ill patients to refuse meaningless life-sustaining treatments. As the range of diseases subject to hospice palliative care was expanded, more challenges and issues need to be addressed by the service providers.
