Clinical Significance of National Patients Sample Analysis: Factors Affecting Mortality and Length of Stay of Organophosphate and Carbamate Poisoned Patients

Abstract

ObjectivesThis study considered whether there could be a change of mortality and length of stay as a result of inter-hospital transfer, clinical department, and size of hospital for patients with organophosphates and carbamates poisoning via National Patients Sample data of the year 2009, which was obtained from Health Insurance Review and Assessment Services (HIRA). The utility and representativeness of the HIRA data as the source of prognosis analysis in poisoned patients were also evaluated.MethodsOrganophosphate and carbamate poisoned patients' mortality and length of stay were analyzed in relation to the initial and final treating hospitals and departments, as well as the presence of inter-hospital transfers.ResultsAmong a total of 146 cases, there were 17 mortality cases, and the mean age was 56.8 ± 19.2 years. The median length of stay was 6 days. There was no inter-hospital or inter-departmental difference in length of stay. However, it significantly increased when inter-hospital transfer occurred (transferred 11 days vs. non-transferred 6 days; p = 0.037). Overall mortality rate was 11.6%. The mortality rate significantly increased when inter-hospital transfer occurred (transferred 23.5% vs. non-transferred 7.0%; p = 0.047), but there was no statistical difference in mortality on inter-hospital and inter-department comparison at the initial treating facility. However, at the final treating facility, there was a significant difference between tertiary and general hospitals (5.1% for tertiary hospitals and 17.3% for general hospitals; p = 0.024), although there was no significant inter-departmental difference.ConclusionsWe demonstrated that hospital, clinical department, length of stay, and mortality could be analyzed using insurance claim data of a specific disease group. Our results also indicated that length of stay and mortality according to inter-hospital transfer could be analyzed, which was previously unknown.

Incidence of Adult In-Hospital Cardiac Arrest Using National Representative Patient Sample in Korea

“…Korea has a special system in which medical claims are made to the NHIS based on the resident registration number of each citizen [1314]. The health insurance claim data contains extensive information on the use of medical services, but it may be distorted in order to receive more compensation [15]. The scale of data also makes it difficult to identify the desired clinical data for analysis.…”

“…The scale of data also makes it difficult to identify the desired clinical data for analysis. HIRA-NIS-2009, verified as having national representativeness, was obtained from the health insurance claims of 2009 [171819], and it is being used in some studies [15]. Based on HIRA-NIS-2009, this study found that the incidence of IHCA was 2.46 per 1,000 admissions.…”

“…All people who resided in Korea were provided with a fee-for-service system by a single healthcare agent, the NHIS. Every detail about the medical treatment, medication, and diagnosis of all patients was coded, and then input to the Health Insurance Review and Assessment Services (HIRA) [131415]. In May 2012, the National In-patients Sample (NIS) data of about 13% of the in-patients and 1% of outpatients with national representativeness from the year 2009, named HIRA-NIS-2009, was provided [1617].…”
