Trend in medical expenditures for patients with kidney diseases: An analysis from a tertiary hospital in Beijing / 北京大学学报(医学版)

OBJECTIVE@#To investigate trends in hospitalization expenditures in adults with kidney disease, to analyze the time pattern of outpatient and inpatient medical expenditures for patients with kidney diseases, and to support the health care reform by exploring the causes.@*METHODS@#Medical expenditure data for kidney disease patients aged ≥18 years from the outpatient and in-patient data of the information center in the Grade?A tertiary hospital in Beijing, China from January 1, 2012, to December 31, 2017, were retrospectively analyzed. It provided descriptive evidence on the time patterns of expenditures per visit and capita, and potential influencing factors of the time changes were further explored.@*RESULTS@#It was found that medical expenditures had increased rapidly from 2012 to 2017. The result showed that the average outpatient expenditure per capita for kidney disease patients was 4 598 yuan in 2012, with an increasing tendency to 11 536 yuan in 2017. There was an obvious increase in the average number of visits (per year) from 3.94 in 2012 to 9.11 in 2017. Meanwhile, the mean inpatient expenditures per capita had an increasing tendency from 323 753 yuan in 2012 to 45 904 yuan in 2017. There was also an increase of mean inpatient expenditures per admission from 27 184 yuan in 2012 to 34 933 yuan in 2017, with a similar number of admissions over the 6 years. The increases in outpatient and inpatient expenditures per capita were driven by different reasons. The increase in outpatient expenditures per capita was driven by the increase of patient visits, while the increase in inpatient expenditures per capita was driven by the increase of the expenditures per admission. Also, drug and medical materials were the two categories that had the largest contribution to the inpatient expenditures. Drug expenses were the highest one, with an average of 12 524 yuan per visit in 2017, accounting for 32.4% of the average total expenditure in that year, while the average cost of consumables was 9 215 yuan, accounting for 23.9%.@*CONCLUSION@#The increase of outpatient expenditures per capita was related to the increase of patient visits. Meanwhile, the growth of drug and consumable costs contributed to the total increase in the total inpatient healthcare costs. It is necessary to increase the proportion of treatment costs and medical service fees in the total expenditure.

Analysis of Medical Use and Costs of Liver Transplant Patients Using National Patients Sample Data

BACKGROUND: Patients experience significant differences in aspects of mortality, quality of life, and costs between during the year of receiving liver transplant (LT) and the subsequent years (post-LT). This study aimed to estimate the medical utilization and cost of LT for patients compared to post-LT patients by using a recent National Patient Sample (NPS) data provided by the Korean Health Insurance Review and Assessment Service (HIRA). METHODS: This study used a subset of the 2015 HIRA-NPS. Patient claims data that included Z944 (Korean Standard Classification of Diseases code for LT status) were selected. Within the selected data, LT patients were identified based on whether the national health insurance number code of Q80 (procedure code for LT surgery) was included, and they were compared to post-LT patients. RESULTS: In the analysis, 330 patients were included. The average cost per patient was 90,066±36,959 thousand KRW and 10,557±9,668 thousand KRW for LT and post-LT patients, respectively. Especially, LT patients' costs for injection/procedure, surgery/treatment, and examination were higher than other costs, being 35,983±18,115 thousand KRW, 28,246±9,408 thousand KRW, and 12,131±6,604 thousand KRW, respectively. For inpatients, the average number of hospitalized days was 63.5±66.0 days for LT patients and 22.3±35.1 days for post-LT patients. CONCLUSION: Compared to post-LT patients, LT patients had higher costs, especially for injection/procedure, surgery/treatment, and examination. Additionally, the LT group had longer hospitalization duration and higher costs for their hospital admission, whereas they did not show a significant difference in number of visits and medical costs for outpatient-care.

Medical Utilization and Antibiotics Use of Prostatitis Patients in Korea

BACKGROUND: Prostatitis, one of the most common diseases of the prostate, is a complex disease with various clinical features. This study aims to analyze the utilization and prescribing patterns of antibiotics in Korean patients with prostatitis between 2008 and 2015. METHODS: We used the National Health Insurance Database complied from the Health Insurance Review and Assessment Service (HIRA). The outcomes included the number of claims, number of patients, medical cost, and length of stay for each year. In addition, the prescribing patterns of antibiotics, including fluoroquinolone, and low-dose use of ciprofloxacin and levofloxacin were investigated. RESULTS: The total number of patients and medical cost increased by 9.5% and 51.7% from 2008 to 2015, respectively. Most prostatitis patients were classified as chronic prostatitis patients. The prescribing proportion of antibiotics for chronic prostatitis outpatients decreased from 71.0% to 66.9% from 2008 to 2015, and fluoroquinolone accounted for more than half of the total antibiotics. Over 80% of prescription of levofloxacin and ciprofloxacin was identified to be for low-dose use. CONCLUSION: Most of the patients with prostatitis experienced pain relief and condition improvement after antibiotic treatment; however, chronic prostatitis and chronic pelvic pain syndrome recur easily. Therefore, active disease management and further studies are needed to enhance our understanding of effective treatment for prostatitis.

The Effect of Stress and Depression on Unmet Medical Needs

BACKGROUND: Mental health issues such as stress and depression have been regarded as major social problems in Korea. We investigated the relationship between stress and depression with unmet medical needs (UMN). METHODS: Using the nationwide database of 2010 Korea National Health and Nutritional Examination Survey (K-NHANES), subjects aged 19 years or above were selected (n=6,055). In the K-NHANES questionnaire, subjects were asked about their UMN experience, severity of stress, and perceived depression lasting at least 2 weeks over the past year. The effects of stress and depression on UMN were analyzed in 4 models established by adding predisposing, enabling and need factors in a step-wise fashion. The risks for UMN were also assessed according to the causes of UMN. RESULTS: Individuals who felt stress ‘very often’ (odds ratio (OR) 3.28, 95% CI=2.23-4.86) and ‘often’ (OR 2.53, 95% CI=1.93-3.31) and who experienced depression (OR 1.68, 95% CI=1.35-2.10) reported significantly elevated UMN rates, and these effects were substantial especially for the individuals who had UMN due to economic constraint. Females, lower education level, lower income, unemployed status, and negative perceptions about health status were found to be additional risk factors for UMN. CONCLUSION: Our results confirmed the risks of stress and depression on UMN. It is strongly advisable to create initiatives to improve mental health, particularly stress and depression, and to fulfill individuals' medical utilization needs.

Analysis of Medical Use and Costs Related to the Management of Liver Cirrhosis Using National Patients Sample Data

BACKGROUND: Liver cirrhosis causes substantial socio-economic burden and is one of the major severe liver diseases in Korea. Nonetheless, there is only a few studies that analyzes disease burden of liver cirrhosis in Korea. Such study must be carried out due to its increasing need from the invention of new drugs for chronic hepatitis and demand for cost-effectiveness analyses. METHODS: Patient sample data with ensured representativeness was analyzed retrospectively to compare the medical costs and uses for patients with compensated cirrhosis and decompensated cirrhosis. Patient claims data that include K74 and K703 from the year of 2014 were selected. Within the selected data, decompensated cirrhosis patient was identified if complications such as ascites (R18), encephalopathy (B190), hepatic failure (K72), peritonitis (K65), or esophageal varices (I85) were included, and they were compared to compensated cirrhosis patients. RESULTS: 6,565 patients were included in the analysis. The average cost per patient was 6,471,020 (SD 8,848,899) KRW and 2,173,203 (4,220,942) KRW for decompensated cirrhosis and compensated cirrhosis, respectively. For inpatients, the average hospitalized days was 38.0 (56.4) days and 27.2 (57.2) days for decompensated cirrhosis and compensated cirrhosis, respectively. For outpatients, the average number of visits was 8.7 (9.1) days and 5.3 (7.5) days for compensated cirrhosis and decompensated cirrhosis, respectively. CONCLUSION: Compared to compensated cirrhosis patients, decompensated cirrhosis patients had higher costs, especially for hospitalization, injection, examination, and drugs administrated within medical institutions.

Factors Influencing Utilization of Medical Care Among Osteoarthritis Patients in Korea: Using 2005 Korean National Health and Nutrition Survey Data / 예방의학회지

OBJECTIVES: The purpose of this study was to define the association between the medical utilization of osteoarthritis patient and its related factors. METHODS: We used the 2005 Korean National Health and Nutrition Survey data and we enrolled 2833 participants who were forty or older and who were diagnosed as having osteoarthritis by a doctor within 1 year and who had suffered from osteoarthritis for more than 3 months. The Andersen behavioral model was used as the analytic framework, and the variables were categorized into predisposing, enabling, and need factors. To determine the influence of each variable on the medical utilization of osteoarthritis patient, we applied hierarchical logistic regression analysis with two stages: the first stage included the predisposing and enabling factors and the second stage included the need factors. RESULTS: On the hierarchical logistic analysis, the variables of personal income, the type of medical security, the duration of arthritis related symptoms within 1 month, the subjective health status and the duration of osteoarthritis showed a statistically significant difference between whether the medical utilization in men patients. And the variables of age, limitation activity due to osteoarthritis, arthritis related symptoms within 1 month, and the subjective health status had a statistically significant difference between whether the medical utilization in women patients. CONCLUSIONS: The patients who tend to receive less care are those suffer less from symptoms of osteoarthritis, those who are within the initial phase, or those with a low-level severity of osteoarthritis. It is necessary to encourage patients to receive the treatment in the initial phase.

A Model Study on Medical Utilization of Workers with Non-Occupational Diseases : An Application of the Theory of Planned Behavior / 대한산업의학회지

OBJECTIVES: This study was carried out to examine the factors influencing the behavioral intention and behavior of workers with non-occupational diseases when utilizing medical facilities, using the theory of planned behavior (TPB). METHODS: The first TPB questionnaire was administered to 3,116 subjects during workers'periodic health examinations at one health examination institute, between September and December in 2000. An investigation of the medical facilities utilization was also conducted by administering a second survey to the 354 subjects (11.4%) adjudged to be workers with non-occupational diseases from the results of the health examination. RESULTS: The medical utilization rate within one month was 41.5%. To investigate the overall relationship between variables, the authors conducted a linear structural equation model analysis, based on the theory of planned behavior. The attitude toward behavior and the subjective norm both positively influenced the behavioral intention (T> or = 2.0). The perceived behavioral control and behavioral intention both positively influenced the behavior (T> or = 2.0) CONCLUSIONS: To improve the medical utilization by workers found to have diseases as a result of their health examination, the implementation of an intervention program will be necessary to increase the behavioral intention and perceived behavioral control, and care givers must pay more attention to eventually converting behavioral intention into actual behaviors.

Fatigue as a Predictor of Medical Utilization, Occupational Accident and Sickness Absence / 대한산업의학회지

OBJECTIVES: This study examined the relationship of fatigue to medical utilization, occupational accident and sickness absence. Subjects and METHODS: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project, 2002~2004). A total of 30,146 employees categorized within the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were recruited. A structured-questionnaire was used to assess the participants' sociodemographics, job-related factors, health-related behaviors, personality trait, self-perceived fatigue (MFS) and the frequency of medical utilization, occupational accident and sickness absence. Data on medical utilization and occupational accident were confirmed from company health records. Chi-square test and logistic regression analysis were used to elucidate the relationship of self-perceived fatigue to medical utilization, occupational accident and sickness absence. RESULTS: In logistic regression analyses, self-perceived fatigue was associated with medical utilization (outpatient), occupational accident and sickness absence although the strength of the associations was higher in the blue collar workers except for medical utilization. For medical utilization, the white collar workers' adjusted odds ratios of outpatient utilization for workers scoring in the third quartile and the highest quartile, compared to workers scoring in the lowest quartile were 1.50 (95% CI: 1.20-1.87) and 2.16 (95% CI: 1.69-2.75), respectively. The blue collar workers' adjusted odds ratios of outpatient utilization for workers scoring in the second (OR: 1.23, 95% CI: 1.06-1.43), third (OR: 1.42, 95% CI: 1.22- 1.66) and highest quartile (OR: 1.83, 95% CI: 1.55-2.17), respectively, compared to workers scoring in the lowest quartile were statistically significant. However, no associations were found between fatigue and inpatient utilization for either the white or blue collar workers. The blue collar workers' adjusted odds ratios of being injured for workers scoring in the second, third and highest quartile were 1.41 (95% CI: 1.00-2.00), 1.57 (95% CI: 1.10-2.22) and 2.41 (95% CI: 1.69-3.44), respectively, compared to those scoring in the lowest quartile, but, those of the white collar workers were not significant. There was more likely to an increased risk of sickness absence in workers scoring in the second, third and highest quartile compared to those scoring in the lowest quartile in both white and blue collar workers, but the magnitudes of risk were higher in the blue collar workers than the white collars workers. CONCLUSION: This result suggests that fatigue is a determinant predictor of medical utilization, occupational accident and sickness absence, and that the pattern of risks for the three outcomes differs according to the occupational type. Some limitations of this study and considerations for future study were also discussed.

Medical Service Utilization and Trends among Korean Elderly in the Last One Year of Life / 예방의학회지

OBJECTIVES: To analyze medical service utilization and trends among the elderly in the last year of life. METHOD: The subjects of this study were people that had died at the age sixty-five and above between January 1st and June 30th 2000 The names of the deceased and their dates of death were collected from the data of the funeral-expenses-receivers of the National Health Insurance Corporation (NHIC). This data was merged with that of the individual medical expenses of the NHIC. RESULTS: In the first half of 2000, 84.2% of the funeral-expenses-receivers (53, 063) utilized medical services during the year prior to their death; 51.0% (27, 042) were female and 49.0% (26, 021) male. In the last twelve months of life, the medical fees, the number of days receiving medical services and the number of days receiving medicine were 3, 107, 935 Won, 47.88 and 153.21, respectively, for each person. As the age of the groups increased, the level of medical service utilization decreased; the change was more obvious in female group. The level of medical service utilization during the twelve months prior to death drastically increased around the time of death. CONCLUSIONS: This study, from an analysis of the level of medical service utilization prior to death, shows a concentrated volume of medical services during a certain time period prior to death.

Change of Medical Utilization Claims in Self-employees before and after the Economic Crisis in Korea / 예방의학회지

OBJECTIVES: To investigate the changing pattern of medical utilization claims following the economic crisis in Korea. METHODS: The original data consisted of the claims of the 'Medical insurance program of self-employees' between 1997 and 1998. The data was selected by medical treatment day ranging between 1 January and 30 June. Medical utilizations were calculated each year by the frequency of claims, visit days for outpatients, length of stay for inpatients, total days of medication, and the sum of expenses. RESULTS: The length of stay as an inpatient in 1998 was decreased 4.7 percent in comparison to 1997. However, inpatient expenses in 1998 increased 10.8 percent as compared to 1997. Inpatient hospital claims in 1998 increased 6.2 percent over 1997, although general hospital inpatient claims in 1998 decreased 3.3 percent in comparison to 1997. The outpatient claim frequency decreased 7.3 in 1998 percent as compared to 1997. Outpatient visit days of in 1998 were decreased 8.5 percent in comparison to that recorded in 1997. Outpatient claim frequencies of 'gu region' in 1998 decreased 10.5 percent comparison to that in 1997, but 'city and gun region' decreased less than 'gu region'. CONCLUSIONS: Medical utilization in 1998 deceased in relation to 1997. Medical utilization by outpatients decreased more than that of inpatients. Medical utilization by 'gu regio n' decreased more than the other regions.

A study of medical utilization and health status for migrant workers in Korea

BACKGROUND: The number of illegal migrant workers has been increasing in Korea since late 1997 in what was called the IMF era. This study was conducted to evaluate and to recognize the medical utilization and health Status for migrant workers in Korea. The goal of this study was to understand the epidemiological characteristics of the migrant workers and family physician's role as a health provider and gate keeper to them and to provide basic data for public health policy. METHODS: In September 1999, self-administered questionnaires were distributed to the migrant workers in Seoul, Sung-Nam, Pucheon and An-Yang. We classified the reasons for clinical encounters and the prescribed drugs by reviewing the medical records of all patients who visited a clinic of shelter for migrant workers in Sung-Nam from January to December 1998 and analysed the report according to death certification of the shelter for migrant workers in Sung Nam from 1994 to September 1999 RESULTS: The major distribution of nationality were from China, Mongo, and Bangladesh (86.9 %). They were mostly between 30 and 39 years old, males are, and unmarried. Most had high school education. The average income was 756,700 won and the average working hours were 11.5 hours per day in migrant workers being in worse condition than those of Korean workers. Classified according to systems, the respiratory(21.2%), musculoskeletal (20.6%), digestive(15.8%), and cardiovascular(12.5%) symptoms were common. Repayment for death was different between before (87.7%) and after IMF era (13.0%), in late 1997. Average medical expenditure was 43,552 won comprising 5% of the total income of subjects only. Most of them did not benefit from medical insurance. CONCLUSION: Migrant workers' situation seemed poor. The patterns of the disease' were similar to those who visit family medicine clinics in general. Family physicians should take more interest in providing a more effective and better care to migrant workers.

Medical Care Utilization of Tuberculosis Patients in Private Sector / 예방의학회지

In this study we analyzed the insurance claims data to investigate the medical care utilization pattern of tuberculosis patients in private sector. We selected the claims of principal or secondary diagnosis with tuberculosis from claims database of National Federation of Medical Insurance, from December 1995 to November 1996. Both spell-based analysis and person-based analysis were carried out. In spell-based analysis, type and location of treatment facilities, distribution of diagnoses, number of outpatient/inpatient treatments were analyzed. Additionally in person-based analysis, number of tuberculosis patients, demographic characteristics, number of treatments per person, frequency and pattern of change in source of care were analyzed. The results were as follows 1. The number of treatments with tuberculosis was 863,641 from 1 December 1995 to 30 November 1996. The number of patients was 313.964. 2. Most of tuberculosis patients in private sector were treated in general hospital(45.8%) and clinics(42.2%) 3. About 77.7% of tuberculosis patients who were treated more than two times did not change the source of carey. 18,9% of tuberculosis patients changed source of care only once. Even when we limited tuberculosis patient to those who were treated more than five times and whose treatment period were longer than six months, 94.7% of patients did not change source of care at all, or changed treatment facility only once. 4. The probability of change in source of care was higher in pulmonary tuberculosis, in twenties, and in rural area respectively than other tuberculosis. In conclusion, healer shopping of tuberculosis patients was not serious as expected. However special attention is needed to pulmonary tuberculosis in twenties and rural area

A path analysis on prisoners' health behavior and medical utilization

In this thesis, Korean prisoners' health behavior and the characteristics of their medical utilization were surveyed and analysed. Because prisoners are inclined to be mediators of communicable diseases or unhealthy behaviors between prison institution and the outside world, health care for prisoners is directly related to the national population. Data were collected through a self-administered survey of 5 Korean prisons out of a total of 38 correctional facilities and analysed in accordance with a causal model based on a path frame, by serial multiple regressions on health behavior, health status, and medical utilization, etc. According to the survey analysis, while prisoners were generally concerned with their health much more than they were before imprisonment, they perceived that their health status had deteriorated after imprisonment, and that their need for health services was increasing gradually during their time in prison. In the path analysis on the causal relations among variables related to the prisoners' health status and medical utilization, the prisoners' characteristics affected their health concern and health behavior, and subsequently affected their health status and medical utilization, respectively. To sum up these exploratory studies on prisoners' health behavior and health service utilization, some efforts to organize a health care system embracing the correctional institution and health care administration should be made on the level of establishing a health care delivery system for special social groups like prisoners.

A Comparative Study on Medical Utilization between Urban and Rural Korea / 예방의학회지

This study was designed to compare the level of medical utilization between the urban and rural areas of Korea and to explain the differences between the two regions. Data from the National Health Interview survey performed by the korean Institute of Health & social Affairs in 1992 were used for this study utilizing a sample size of 21,841 people. The level of medical utilization such as the number of physician visits and the number of hospital admissions was compared between the regions with ANOVA. Various determinants for medical use were also compared by univariate analysis. Statistical models which included enabling factors, predisposing factors, need factors and region were constructed for bivariate analysis in order to further elucidate the level of medical utilization. The results were as follows: 1. There was greater medical use, both in terms of physician visits and inpatient care in the rural areas in spite of insufficient health resources. The particular reasons for higher medical utilization in rural areas were attributed to a higher number of initial physician visits as well as a longer the length of stay per hospital admission. Therefore, indicators representing the degree of met need (utilization/need) showed no significant difference between rural and urban areas in spite of the fact that the medical need is larger in rural areas. 2. Use of public health facilities received a significant portion of physician visits in the rural area. The government's effort to enhance primary health care through health centers, health subcenters and the nurse practitioner's post in rural areas has contributed to the increase of access to medical care in the rural areas. 3. There were some differences in the socio-demographic characteristics between two regions; There were more elderly people over the age of 65; unstable marital status, less education and lower incomes also characterized the rural areas. Therefore, among rural people, there were more predisposing factors for medical use. Additionally, need factors such as poor self-reported health status and high morbidity level were also high in the rural area. 4. In contrast it was learned that, the supply of health resources was mostly concentrated in the urban areas except for public health facilities. Therefore, geographical access to medical care was lower in the rural area both in terms travel time and travel cost. 5. The coefficient of the region variable was insignificant in the regression model which controlled the supply factor only However, utilization was significantly higher in urban areas if the model included predisposing factors and need factors in addition to the supply factor. The results were interpreted as rural people have greater medical needs.

Medical utilization of the Hand Injured Patients among the Industrial Accident Compensation Insured / 대한산업의학회지

This study attempts to assess the status of hand injured patients and their medical care utilization among the industrial accident compensation insured. The study subjects were the 8,648 hand injured patients (2,951 inpatients and 5,697 outpatients) who were attended in the medical facilities of Seoul area from January, 1986 to August, 1988. The following results were obtained. 1. About 90% of hand injured patients were male, and about 62% of them were less than 30 years of age. 44.4% of inpatients recieved treatment in general hospital and 42.0% of outpatients in clinic. 2. The highest mean medical cost by facility were 929,000 won of general hospital in inpatient, and 108,000 won of clinic and general hospital in outpatient. 3. The highest mean medical cost by injury were 690,000 won of amputation in inpatient and 126,000 won of fracture in outpatient. 4. The longest mean patient days by facility 25.3 days of general hospital in inpatient and 20.7 days of clinic in outpatient. According to the type of injury, 23.1 days of open wound in inpatient and 23.0 days of fracture in outpatient. 5. The, highest mean medical cost per day by facility was 39,000 won of inpatient and 8,000 won of outpatient in general hospital. According to the type of injury, these were 34,000 won of dislocation and burns in inpatient and 7,000 won of dislocation and burns in outpatient.
