Concordance between the underlying causes of death on death certificates written by three emergency physicians

Objective This study was conducted to evaluate the concordance between the underlying causes of death (UCOD) on the death certificates written by three emergency physicians (EPs). We investigated errors on the death certificates committed by each EP. Methods This study included 106 patients issued a death certificate in the emergency department of an academic hospital. Three EPs reviewed the medical records retrospectively and completed 106 death certificates independently. The selection of the UCOD on the death certificates by each EP (EP-UCOD) was based on the general principle or selection rules. The gold standard UCOD (GS-UCOD) was determined for each patient by unanimous consent between three EPs. We also compared between the EP-UCOD and the GS-UCOD. In addition, we compared between UCODs of three EPs. The errors on the death certificates were investigated by each EP. Results The rates of concordance between EP-UCOD and the GS-UCOD were 86%, 81%, and 67% for EP-A, EP-B, and EP-C, respectively. The concordance rates between EP-A and EP-B were the highest overall percent agreement (0.783), and those between EP-A and EP-C were the lowest overall percent agreement (0.651). Although each EP had differences in the errors they committed, none of them listed the mode of dying as UCOD. Conclusion This study confirmed that each EP wrote death certificates indicating different causes of death for the same decedents; however, the three EPs made fewer errors on the patients’ death certificates compared with those reported in previous studies

However, little is known about how the two key players, patients and physicians, view the current status of primary care in Korea. This study aims to understand what problems they perceive in respect to the key components of primary care. Methods: We conducted two focus groups; one with six patients and the other with six physicians. We designed and modified the guidelines for each focus group discussion through repeated review and discussion among all authors and then we conducted the groups with a professional interviewer at Gallup Korea. After the focus groups we analyzed the verbatim transcriptions to identify specific meanings and potential implications. Results: From the study we identified that the patients and physicians did not have a correct understanding about the role of primary care. We also identified a significant discrepancy between their perception of primary care. In particular, the patient group perceived the quality of primary care to be poor and unsatisfactory while the physician group perceived the quality of primary care to be better in Korea than in other countries. Conclusions: The focus group discussions revealed that such discrepancies in perception have resulted from Koreas distorted healthcare delivery system, undifferentiated roles among healthcare organizations, patients freedom of choice in selecting healthcare providers and other institutional factors. There are several steps that should be taken to promote primary care in Korea. First, we should undertake efforts to improve the quality of primary care provided by physicians. Second, we should inform the general public about using clinics instead of hospitals for the treatment of simple or minor diseases. Third, we should introduce a new compensation scheme to compensate physicians for services related to health education, disease prevention, behavioral change and nutrition consultation. Finally, we should provide additional reimbursement so that primary care physicians can extend their office hours to better meet the needs of patients.Peer Reviewe

Income-related inequality in quality-adjusted life expectancy in Korea at the national and district levels

Background The aim of this study was to measure differences in quality-adjusted life expectancy (QALE) by income in Korea at the national and district levels. Methods Mortality rates and EuroQol-5D (EQ-5D) scores were obtained from the National Health Information Database of the National Health Insurance Service and the Korea Community Health Survey, respectively. QALE and differences in QALE among income quintiles were calculated using combined 2008–2014 data for 245 districts in Korea. Correlation analyses were conducted to investigate the associations of neighborhood characteristics with QALE and income gaps therein. Results QALE showed a graded pattern of inequality according to income, and increased over time for all levels of income and in both sexes, except for low-income quintiles among women, resulting in a widened inequality in QALE among women. In all 245 districts, pro-rich inequalities in QALE were found in both men and women. Districts with higher QALE and smaller income gaps in QALE were concentrated in metropolitan areas, while districts with lower QALE and larger income gaps in QALE were found in rural areas. QALE and differences in QALE by income showed relatively close correlations with socioeconomic characteristics, but relatively weak correlations with health behaviors, except for smoking and indicators related to medical resources. Conclusions This study provides evidence of income-based inequalities in health measured by QALE in all subnational areas in Korea. Furthermore, QALE and differences in QALE by income were closely associated with neighborhood-level socioeconomic characteristics.This research was supported by a grant of the Korea Health Technology R&D Project through the Korea Health Industry Development Institute (KHIDI), funded by the Ministry of Health & Welfare, Republic of Korea (grant number: HI18C0446)

Medical litigation experience of the victim of medical accident: a qualitative case study

This study aims to demonstrate a comprehensive understanding of the life experience of victims of medical accidents after medical accidents and medical litigations. A single victim of a medical accident participated in the study. Six upper categories were derived as the results: “frustration and anger toward medical accident occurrence,” “desolated struggle for medical litigation,” “distrust of medical litigation related legal profession,” “accepting myself with a disability caused by a medical accident,” “a life with far more unexpected challenges as an athlete with disabilities,” and “find new meaning after the medical accident.” The participant was experiencing physical and psychological distress in the process of accepting the medical accident and the disability. In addition, the participant was exposed to the secondary psychological distress from the medical profession, lawyer, and legal profession in the peculiar situation of medical litigation, and to the third psychological distress in life living as a disabled person

Trend analysis of major cancer statistics according to sex and severity levels in Korea.

Existing epidemiologic reports or studies of cancer statistics in Korea lack sufficient data on cancer severity distributions and observed survival rates. This study analyzed trends in major cancer statistics according to sex and severity levels in Korea from 2006 to 2013. We included eight cancers (hepatocellular carcinoma, and thyroid, colorectal, gastric, lung, prostate, breast, and cervical cancer), using Korea Central Cancer Registry data. Severity level was classified by Surveillance, Epidemiology, and End Results (SEER) stage as follows: localized, regional, distant, or unknown. Numbers of incident cancer cases from 2006 to 2013 were described by sex and SEER stage. We estimated up to 8-year observed survival rates of major cancers by sex and SEER stage, and provided prevalence rates by sex and SEER stage in 2011, 2012, and 2013. Although increases in new cancer cases are slowing and the total number of incident cancer cases in 2013 decreased for the first time since 2006, the number of prevalent cancer cases was 663,530 in 2013, an increase of 13.3% compared to 2011. Among the five cancers affecting both sexes, sex-related differences in 5-year observed survival rates for lung cancer were greatest in the localized stage (men, 31.9%; women, 48.1%), regional stage (men, 20.0%; women, 31.3%), and unknown stage (men, 24.3%; women, 37.5%). The sum of the proportions of localized and regional stages for thyroid and breast cancer was over 90% in 2013, while the sum of the proportions of localized and regional stages for lung cancer was only 56.7% in 2013. Differences in observed survival rates between men and women were prominent in lung cancer for all SEER stages. The reported epidemiologic data from this study can be used to obtain a more valid measure of cancer burden using a summary measure of population health

Occurrence of patient safety incidents during cancer screening: A cross-sectional investigation of the general public

This study aimed to explore the various types and frequency of patient safety incidents (PSIs) during a cancer screening health examination for the general public of Ulsan Metropolitan City, South Korea. Furthermore, the associated elements and responses to PSIs during a cancer screening were examined. The survey, conducted in the five districts of Ulsan, was completed by residents aged 19 years and older who agreed to participate. Descriptive analysis, Chi-square or Fisher exact test, and multivariable logistic regression were performed to analyze the data. A total of 620 participants completed the survey, with 11 (1.8%) individuals who experienced PSIs themselves and 11 (1.8%) by their family members. The highest type of PSIs was those related to procedures. The multivariable logistic regression analysis showed no significant variables associated with experiencing PSIs during cancer screening. However, there was a significant association between the judgment of medical error occurrence and level of patient harm both in experience by family members and total experience of PSIs (P < .05). There was also a significant difference between with and without an experience of PSIs disclosure (P < .001). This study comprehensively analyzed the types and extent of PSIs experienced by Korean individuals and their family members in Ulsan. These findings suggest that patient safety issues during cancer screening should not be overlooked. Furthermore, an investigation system to regularly monitor PSIs in cancer screening should be developed and established
