Psychiatric inpatient expenditures and public health insurance programmes: analysis of a national database covering the entire South Korean population

Descriptive analysis of prevalence and medical expenses of cancer, cardio-cerebrovascular disease, psychiatric disease, and musculoskeletal disease in Korean firefighters

Background

Firefighters are exposed to many dangerous working conditions. Many studies have identified the risk of disease for firefighters, but only a few studies have addressed the medical expenses of firefighters, which represents a concrete scale of disease. Our purpose in this study was to determine the medical expenditures of firefighters to assess the overall scale of disease in Korea. We focused on cancer, mental disorders, cardio-cerebrovascular disease, and musculoskeletal disease, the prevalence of which was expected to be high in firefighters.

Methods

This study utilized National Health Insurance Service data. We targeted firefighters, police officers, and government officials. We classified disease based on the 10th revision of the International Statistical Classification of Diseases and Related Health Problems codes. We compared prevalence by the age-standardized prevalence rate, considering standard distribution of the population. Medical expenditure of disease was defined as outpatient fees, hospitalization fees, and drug costs. Total medical expenditures were calculated by the sum of those 3 categories.

Results

The age-standardized prevalence of cancer, mental disorders, and cardiovascular disease in firefighters was slightly higher than or similar to that of government officials and police officers (no significant difference). However, medical expenditures for stomach cancer, mental disorders, and most cardio-cerebrovascular diseases were higher in firefighters than in others. In particular, firefighters spent 12 times more money for ischemic heart disease than did government officials. Of musculoskeletal diseases, lumbar disc disorder had the highest expenditures among firefighters.

Conclusions

The age-standardized prevalence of most of diseases of firefighters was not as high as in the other groups, but the medical expenses of firefighters were much higher than those of government officials and police officers.

Rising co-payments coincide with unwanted effects on continuity of healthcare for patients with schizophrenia in the Netherlands

BACKGROUND

Co-payments, used to control rising costs of healthcare, may lead to disruption of appropriate outpatient care and to increases in acute crisis treatment or hospital admission in patients with schizophrenia. An abrupt rise in co-payments in 2012 in the Netherlands offered a natural experiment to study the effects of co-payments on continuity of healthcare in schizophrenia.

METHODS

Retrospective longitudinal registry-based cohort study. Outcome measures were (i) continuity of elective (planned) psychiatric care (outpatient care and/or antipsychotic medication); (ii) acute psychiatric care (crisis treatment and hospital admission); and (iii) somatic care per quarter of the years 2009-2014.

RESULTS

10 911 patients with schizophrenia were included. During the six-year follow-up period the level of elective psychiatric outpatient care (-20%); and acute psychiatric care (-37%) decreased. Treatment restricted to antipsychotic medication (without concurrent outpatient psychiatric care) increased (67%). The use of somatic care also increased (24%). Use of acute psychiatric care was highest in quarters when only antipsychotic medication was received. The majority (59%) of patients received continuous elective psychiatric care in 2009-2014. Patients receiving continuous care needed only half the acute psychiatric care needed by patients not in continuous care. On top of these trends time series analysis (ARIMA) showed that the abrupt rise in co-payments from 2012 onwards coincided with significant increases in stand-alone treatment with antipsychotic medication and acute psychiatric care.

CONCLUSIONS

The use of psychiatric care decreased substantially among a cohort of patients with schizophrenia. The high rise in co-payments from 2012 onwards coincided with significant increases in stand-alone treatment with antipsychotic medication and acute psychiatric care.

Direct medical costs for patients with schizophrenia: a 4-year cohort study from health insurance claims data in Guangzhou city, Southern China

BACKGROUND

Schizophrenia is one of the leading public health issues in psychiatry and imposes a heavy financial burden on the healthcare systems. This study aims to report the direct medical costs and the associated factors for patients with schizophrenia in Guangzhou city, Southern China.

METHODS

This was a retrospective 4-year cohort study. Data were obtained from urban health insurance claims databases of Guangzhou city, which contains patients' sociodemographic characteristics, direct medical costs of inpatient and outpatient care. The study cohort (including all the reimbursement claims submitted for schizophrenia inpatient care during November 2010 and October 2014) was identified using the International Classification of Diseases Tenth version (F20). Their outpatient care information was merged from outpatient claims database. Descriptive analysis and the multivariate regression analysis based on Generalized Estimating Equations model were conducted.

RESULTS

A total of 2971 patients were identified in the baseline. The cohort had a mean age of 50.3 years old, 60.6% were male, and 67.0% received medical treatment in the tertiary hospitals. The average annual length of stay was 254.7 days. The average annual total direct medical costs per patient was 41,972.4 Chinese Yuan (CNY) ($6852.5). The inpatient costs remained as the key component of total medical costs. The Urban Employee Basic Medical Insurance enrollees with schizophrenia had higher average costs for hospitalization (CNY42,375.1) than the Urban Resident Basic Medical Insurance enrollees (CNY40,917.3), and had higher reimbursement rate (85.8% and 61.5%). The non-medication treatment costs accounted for the biggest proportion of inpatient costs for both schemes (55.8% and 64.7%). Regression analysis suggested that insurance type, age, hospital levels, and length of stay were significantly associated with inpatient costs of schizophrenia.

CONCLUSIONS

The direct annual medical costs of schizophrenia were high and varied by types of insurance in urban China. The findings of this study provide vital information to understand the burden of schizophrenia in China. Results of this study can help decision-makers assess the financial impact of schizophrenia.

Psychiatric disorders as main discharge diagnosis by the Portuguese oldest old from 2000 to 2014: exploring national acute inpatient admissions

ABSTRACTBackground:Mental health problems have been reported as one of the principal causes of incapacity and morbidity. According to the World Health Organization approximately 15% of adults aged 60+ and over suffer from a mental disorder. In the oldest old population, a higher deterioration in the mental state is expected, which is ought to increase the risk of incidence of mental problems and use of healthcare services. The aim of this study is to examine inpatient episodes with a mental disorder coded as primary discharge diagnosis between 2000 and 2014 by patients aged 80+ in Portugal mainland.

METHOD

Exploratory descriptive analyses of data regarding the number of episodes and coded diagnosis on admission were performed.

RESULTS

From a total of 1,837,613 inpatient episodes, 16,430 (0.9%) correspond to episodes having a psychiatric disorder as a primary discharge diagnosis. Delirium, dementia and amnestic and other cognitive disorders (60.1%), alcohol-related disorders (17.7%) and mood disorders (8.6%) were the most common diagnosis. An analysis by age group revealed that among octogenarians and nonagenarians delirium, dementia, and amnestic and other cognitive disorders were the most common diagnosis; in the centenarian group; however, these were outweighed by alcohol-related disorders.

CONCLUSIONS

Findings from this study document the importance of neurocognitive disorders as a primary reason for hospitalization in the oldest old, but also highlights the need of paying attention to other mental disorders among this age group. Further studies should examine the prevalence of medical comorbidities in patients with mental disorders.

Regional supply of outreach service and length of stay in psychiatric hospital among patients with schizophrenia: National case mix data analysis in Japan

Several clinical trials have demonstrated that linkage to an outreach service can prevent prolonged length of stay of patients at psychiatric hospitals. However, there has been no investigation of the association between length of stay in psychiatric hospital and regional supply of outreach services using national case mix data. The aim of this study was to clarify the relationship between length of stay in psychiatric hospital and regional supply of outreach services. We used data from the National Patient Survey in Japan, a nationally representative cross-sectional survey of inpatient care conducted every three years from 1996 to 2014. Data from 42,268 patients with schizophrenia who had been admitted to psychiatric hospitals were analyzed. After controlling for patient and regional characteristics, patients in regions with fewer number of visits for psychiatric nursing care at home had significantly longer length of stay in psychiatric hospitals. This finding implies that enhancement of the regional supply of outreach services would prevent prolonged length of stay in psychiatric hospitals.

Towards Actualizing the Value Potential of Korea Health Insurance Review and Assessment (HIRA) Data as a Resource for Health Research: Strengths, Limitations, Applications, and Strategies for Optimal Use of HIRA Data

Health Insurance and Review Assessment (HIRA) in South Korea, also called National Health Insurance (NHI) data, is a repository of claims data collected in the process of reimbursing healthcare providers. Under the universal coverage system, having fee-for-services covering all citizens in South Korea, HIRA contains comprehensive and rich information pertaining to healthcare services such as treatments, pharmaceuticals, procedures, and diagnoses for almost 50 million beneficiaries. This corpus of HIRA data, which constitutes a large repository of data in the healthcare sector, has enormous potential to create value in several ways: enhancing the efficiency of the healthcare delivery system without compromising quality of care; adding supporting evidence for a given intervention; and providing the information needed to prevent (or monitor) adverse events. In order to actualize this potential, HIRA data need to actively be utilized for research. Thus understanding this data would greatly enhance this potential. We introduce HIRA data as an important source for health research and provide guidelines for researchers who are currently utilizing HIRA, or interested in doing so, to answer their research questions. We present the characteristics and structure of HIRA data. We discuss strengths and limitations that should be considered in conducting research with HIRA data and suggest strategies for optimal utilization of HIRA data by reviewing published research using HIRA data.

Trends in elderly psychiatric admissions to the Brazilian public health care system

Objective:

To evaluate trends in psychiatric bed occupancy by elderly inpatients in the Brazilian public health care system between 2000 and 2010 and to determine the leading psychiatric diagnosis for hospital admissions.

Methods:

Data from all 895,476 elderly psychiatric admissions recorded in the Brazilian Public Health Care Database (DATASUS) between January 2000 and February 2010 were analyzed. Polynomial regression models with estimated curve models were used to determine the trends. The number of inpatient days was calculated for the overall psychiatric admissions and according to specific diagnoses.

Results:

A moderate decreasing trend (p < 0.001) in the number of inpatient days was observed in all geriatric psychiatric admissions (R² = 0.768) and in admissions for organic mental disorders (R² = 0.823), disorders due to psychoactive substance use (R² = 0.767), schizophrenia (R² = 0.680), and other diagnoses (R² = 0.770), but not for mood disorders (R² = 0.472). Most admissions (60 to 65%) were due to schizophrenia.

Conclusion:

There was a decreasing trend in inpatient days for elderly psychiatric patients between 2000 and 2010. The highest bed occupancy was due to schizophrenia, schizotypal, and delusional disorders.

Schizophrenia in the Netherlands: Continuity of Care with Better Quality of Care for Less Medical Costs

Background

Patients with schizophrenia need continuous elective medical care which includes psychiatric treatment, antipsychotic medication and somatic health care. The objective of this study is to assess whether continuous elective psychiatric is associated with less health care costs due to less inpatient treatment.

Methods

Data concerning antipsychotic medication and psychiatric and somatic health care of patients with schizophrenia in the claims data of Agis Health Insurance were collected over 2008–2011 in the Netherlands. Included were 7,392 patients under 70 years of age with schizophrenia in 2008, insured during the whole period. We assessed the relationship between continuous elective psychiatric care and the outcome measures: acute treatment events, psychiatric hospitalization, somatic care and health care costs.

Results

Continuous elective psychiatric care was accessed by 73% of the patients during the entire three year follow-up period. These patients received mostly outpatient care and accessed more somatic care, at a total cost of €36,485 in three years, than those without continuous care. In the groups accessing fewer or no years of elective care 34%-68% had inpatient care and acute treatment events, while accessing less somatic care at average total costs of medical care from €33,284 to €64,509.

Conclusions

Continuous elective mental and somatic care for 73% of the patients with schizophrenia showed better quality of care at lower costs. Providing continuous elective care to the remaining patients may improve health while reducing acute illness episodes.

Factors associated with long-stay status in patients with schizophrenia: an analysis of national databases covering the entire Korean population

BACKGROUND

Admissions lasting over six months (long-stay) occur frequently among patients with schizophrenia in South Korea.

AIMS

To identify some patient-level and institution-level factors associated with long-stay status of patients with schizophrenia.

METHODS

This is a retrospective cross-sectional study. We analysed a nationwide population-based reimbursement claims data set consisting of 496,338 claims for 58,287 patients with schizophrenia between 1 January 2005 and 30 June 2006. A two-level random effects logistic regression model was used to identify those factors.

RESULTS

Age (<20 years (ref), 60-69 (OR 2.000, 95% CI: 1.640-2.438), ≥ 70 (2.068, 1.682-2.543)), male gender (1.192, 1.144-1.242), type of national health insurance plan (national health insurance (ref), Medical Care Aid Type 1 (4.299, 4.024-4.593)), secondary diagnosis (none (ref), psychiatric diagnosis (0.719, 0.666-0.777), non-psychiatric diagnosis (0.918, 0.850-0.991)) and type of institution (clinic (ref), psychiatric hospital (2.769, 1.507-5.087)) were associated with likelihood of long-stay status. Institutional variable associated with long-stay status included a higher number of beds (1.073, 1.013-1.137). The number of professionals (0.752, 0.646-0.876) showed negative association with long-stay status.

CONCLUSIONS

Researchers could improve their assessment of long-stay status of patients with schizophrenia by using a two-level analysis including patient-level and institution-level factors. This study suggests that mental health interventions to reduce the long stay of patients with schizophrenia focus on older male patients, those enrolled in a national medical care aid programme and those admitted to psychiatric hospitals.
