PURPOSE: This study was conducted to identify and analyze the trends of theory-based research published in Asian Oncology Nursing (AON) from 2011 to 2017. METHODS: We analyzed 22 theory-based studies taken from among the 232 studies published in AON for 7years. We analyzed the framework developed by researchers, descriptive summaries of theory, keyword classification of nursing meta-paradigms, the generic character of the studies, and the type of research designs. RESULTS: A total of 23 theories were applied in the 22 (9.5%) studies. ‘Nursing’ was the most prevalent field of study (34.8%). In the field of study of theory, nursing theory was the largest with eight (34.8%), and in the method of theory utilization, all 22 studies were theoretical applications 3 middle-range theories were most prevalent. In the keyword classification using meta-paradigm in nursing, we found 83 key words. Among them, ‘Health’ related key words were most frequent (53), followed by ‘Cancer’ keywords (13). CONCLUSION: AON has a high ratio of theoretical study compared to other journals, but the ratio is still less than 10%, which is still weak. Therefore, it is believed that the attention to, utilization of, application, and institutional establishment of nursing theory should be necessary.

OBJECTIVES: This study tried to explore the prevalence of chronic physical diseases in patients with schizophrenia and its effects on total medical costs. METHODS: The Health Insurance Review and Assessment Service data in 2014–2015 was employed. Only the injuries and diseases, identically diagnosed 3 times or more as a major or minor injury and disease, were classified into chronic physical diseases to improve data accuracy. Total medical costs included out-of-pocket and insurer's costs from health care system perspective. RESULTS: It was shown that 24.5%, 17.3% and 23.4% of schizophrenia patients had one, two and three or more chronic physical diseases, respectively. There was a high prevalence of not only metabolic, but also musculoskeletal, diseases in those patients. The amount of 2015 total medical costs of patients with schizophrenia in 2014 was about 1.08 trillion won. The factors affecting the costs included sex, age, number of chronic physical diseases, and health insurance status. CONCLUSIONS: It is considered that clinical practice guidelines based on personal diseases may not sufficiently solve the problems for comorbidities in schizophrenia patients. Accordingly, it should be required to develop models for new types of medical systems capable of treating and caring varied illnesses at the same time.

Airway stenting has become a common treatment for malignant central airway obstruction. Most airway stents are well tolerated, and life-threatening complications are very rare. Here we describe the case of a life-threatening obstruction due to accumulated respiratory secretions. A 33-year-old man had a massive large cell neuroendocrine carcinoma in the anterior mediastinum, which caused extensive extrinsic compression of the whole trachea. Airway stents were successfully inserted into the whole trachea but 1 week after the procedure, the patient complained of worsening dyspnea due to sticky respiratory secretions accumulated inside the stents. Because the patient could not expectorate a large amount of sticky secretions, frequent bronchoscopic toiletings were performed for 2 months. The stent was well maintained for 7 months till the enlarged tumor causes extrinsic compression because stent revision was performed. About 1 year after the first stent insertion, the patient was admitted to the intensive care unit and intubated because of obstruction of the stent by organized secretions. Fortunately, these secretions were successfully removed and the patient was discharged without any sequelae. Thus, respiratory secretions can cause life-threatening complications after airway stent insertion. Clinicians should be aware of this, and careful examination and close follow-up of such patients are needed.

BACKGROUND: Several studies have been conducted regarding people with disabilities, however no studies have estimated the disease burden due to premature death. As such, we aimed to compare the years of life lost (YLLs) due to premature death between a population with disabilities and the total population of Korea. METHODS: To calculate the YLLs in people with disabilities, we combined disability registration data from the 2002–2011 Ministry of Health and Welfare of Korea and the causes of mortality data by Statistics Korea for 3,158,231 people. RESULTS: YLLs of people with disabilities were 517,337, which accounted for 23.4% of YLLs of the total population. YLLs per 100,000 people with disabilities were approximately 3.8 times higher than those in the total Korean population. Ischemic stroke was associated with the highest YLLs per 100,000 people, followed by ischemic heart disease, hemorrhagic, and other non-ischemic stroke, diabetes mellitus, and self-harm. Among individuals with physical disabilities, ischemic heart disease was associated with the highest YLLs. For intellectual disability, epilepsy contributed to the most YLLs. For individuals with mental disability, self-harm was the largest contributor to YLLs. CONCLUSION: The burden of disease was higher in the population with disabilities than that in the general population. Cardiovascular diseases and cancer had a higher burden of disease than did other diseases in the population with disabilities; thus, overall, non-communicable diseases have a higher burden of disease than communicable diseases or injuries in the population with disabilities than in the general population.

BACKGROUND: Disease burden can be represented by health-related parameters such as disability-adjusted life years and economic burden. Economic burden is an important index, as it estimates the maximum possible cost reduction if a disease is prevented. This study aimed to determine the economic burden of 238 diseases and 22 injuries in Korea in 2015. METHODS: Economic burden was estimated with a human resources approach from a social perspective, and direct and indirect costs were calculated from insurance claims data and a cause of death database. Direct costs were divided into medical costs (including hospital admission, outpatient visit, and medication use) and nonmedical costs (including transportation and caregiver costs). Indirect costs from lost productivity, either from the use of healthcare service or premature death, were analyzed. RESULTS: In 2015, the estimated economic burden was USD 133.7 billion (direct: USD 65.5 billion, indirect: USD 68.2 billion). The total cost of communicable diseases was USD 16.0 billion (11.9%); non-communicable diseases, USD 92.3 billion (69.1%); and injuries, USD 25.4 billion (19.0%). Self-harm had the highest costs (USD 8.3 billion), followed by low back pain (LBP, USD 6.6 billion). For men, self-harm had the highest cost (USD 7.1 billion), while LBP was the leading cost (USD 3.7 billion) for women. CONCLUSION A high percentage of Korea's total socioeconomic disease burden is due to chronic diseases; however, unnoticed conditions such as infectious diseases, injuries, and LBP are high in certain age groups and differ by gender, emphasizing the need for targeted social interventions to manage and prevent disease risk factors.

Background: The impact of reflux esophagitis on the decline of lung function has been rarely reported. This study was performed to evaluate the association between erosive reflux esophagitis and lung function changes. Methods: We included patients with normal lung function who underwent esophagogastroduodenoscopy for health screening from a health screening center. Patients with persistent erosive reflux esophagitis on two discrete endoscopic examinations were designated as the erosive reflux esophagitis group. We also selected patients without erosive reflux esophagitis and matched them 1:4 with patients from the erosive reflux esophagitis group. We estimated annual forced expiratory volume in 1 second (FEV1 ) and forced vital capacity (FVC) changes from baseline and compared these estimates by the linear mixed regression model. We also estimated the biannual incidence of chronic obstructive pulmonary disease (COPD). Results: In total, 1,050 patients (210 patients with erosive reflux esophagitis, and 840 matched controls) were included. The median follow-up duration for spirometry was six years. In patients with erosive reflux esophagitis, mild reflux esophagitis (A grade) was most common (165 patients, 78.6%). The adjusted annual FEV1 change in patients with erosive reflux esophagitis was −51.8 mL/yr, while it decreased by 46.8 mL/yr in controls (P = 0.270).The adjusted annual FVC decline was similar between the two groups (−55.8 vs. −50.5 mL/ yr, P = 0.215). The estimated COPD incidence during the follow-up period was not different between the erosive reflux esophagitis and control groups. Conclusion In patients with normal lung function, the presence of erosive reflux esophagitis did not affect the annual declines in FEV1 or FVC.

Sarcoidosis is a multi-organ disease with various clinical manifestations. The lung is the most common site of manifestation; however, unusual findings may delay the correct diagnosis of sarcoidosis. Here we report a case of 32-year-old man with 4-month history of neck mass. Radiological findings revealed multiple pulmonary parenchymal nodules, with initial biopsy results of his neck lymph node showing chronic granuloma with focal necrosis. The patient was treated with anti-tuberculosis medications, but the size of the nodules did not change. Biopsy was performed from one of his pulmonary nodules, which revealed chronic granuloma without necrosis. Therefore, the patient was diagnosed with sarcoidosis. We present a case of sarcoidosis with multiple lung parenchymal nodules that is uncommon in Korea, with an aim to alert physicians of such unusual presentations.

Globally, the incidence of communicable diseases has decreased compared to non-communicable diseases. However, chronic communicable diseases such as HIV/AIDS and tuberculosis persist worldwide. Furthermore, emerging new infections such as H1N1 influenza pose a new threat to public health. However, most studies have focused on non-communicable diseases because of their increasing incidence, with fewer studies investigating communicable diseases. Therefore, we estimated the burden of communicable diseases in Korea using national representative 2012 data. To estimate the disability-adjusted life years (DALY), we used cause of death data from the Statistics Korea to estimate the years of life lost (YLL), applied the Korean garbage code algorithm, and used national claims data from the National Health Insurance Service (NHIS) to estimate years lived with disability (YLD). In 2012, the total DALYs of communicable disease were 445 per 100,000, with 129 YLLs per 100,000 and 316 YLDs per 100,000. The total DALYs in men were 468 per 100,000, greater than the 422 per 100,000 DALYs seen in women. The DALYs of lower respiratory infections were the highest value among communicable diseases at 143/100,000 DALYs followed by tuberculosis and upper respiratory infections. The 40-49 years old age group had the largest number of total DALYs. In contrast, the over 80 years old age group had the largest number of total DALYs per 100,000 followed by the 70-79 and 0-9 years old age groups. These results enable the prioritization of interventions related to communicable diseases and can be used for evidence-based public health policies.
