Background The Web is an important source of health information, but the quality of such online information is highly variable. This study evaluates the quality of health articles published on Naver News, Korea’s most popular portal, using the Health Information Quality Assessment Tool (HIQUAL).
Methods We collected 712 health-related articles published on Naver News from May 1 to 7, 2023. After applying exclusion criteria, we selected 116 articles for analysis. Two clinicians independently assessed the quality of these articles using the HIQUAL, which scores articles based on five domains: “reliability,” “usefulness,” “understandability,” “sufficiency,” and “transparency.”
Results Overall article quality was generally considered recommendable (mean±standard deviation: 7.52±2.00). “Usefulness,” one item of “reliability,” and “understandability” were the three items with the highest levels of satisfaction. “Sufficiency” criteria for costs, risks, and benefits received low scores. Quality scores for articles focused on health risk factors and intervention showed a statistically significant difference.
Conclusion While the overall quality of health information in Korean online newspaper articles is acceptable, room for improvement remains in some areas, particularly with regard to the fair presentation of costs, risks, and benefits. The study highlights the need for ongoing quality improvement and evaluation initiatives for online health information.
Background Patients’ perceptions of care tend to correlate with the quality of care provided. Different health care systems and service environments may show different associations between types of usual source of care (USC) and overall service quality assessment. We attempted to analyze this association as a benefit of having a USC.
Methods This study used the 2012 Korea Health Panel data version 1.1 as representative national household survey data. The total number of subjects aged 18 years or more was 12,708. The number of subjects in the final analysis was 10,665. Multiple logistic regression analysis was used to assess the association between types of USC and overall health care service quality. The main outcome variable was users’ ratings of the quality of health care service.
Results People having a usual doctor (n=1,796) were more likely to positively assess the quality of health care they received than those not having a USC (n=7,920; odds ratio [OR], 1.39; 95% confidence interval [CI], 1.20–1.60) or with those having only a place as a USC without a usual doctor (n=949; OR, 1.29; 95% CI, 1.05–1.58) after adjustment for demographic characteristics and health-related variables.
Conclusion People having a usual doctor rated overall health care service quality as high, which might be due to benefits of primary care attributes related to usual doctors. Further studies are needed to elucidate the causal relationship. This finding implies that health policies encouraging people to have a usual doctor are needed in Korea.

Background Because low quality trials may lead to wrong conclusions, quality assessments are necessary. Thus, this study scrutinizes randomized controlled trials (RCTs) in the Journal of the Korean Academy of Family Medicine (KAFM) to assess the quantity and the quality. Methods: Upon extracting randomized controlled trials from all the articles published in the Journal of the KAFM from 1980 to 2005, assessments were made on the Jadad scale and the adequacy of allocation concealment. The selections and assessments were performed independently by two researchers, and adjustment of the differences were done by a third-party researcher. In addition, the factors that may affect the quality levels were analyzed. Results: Twenty-three trials were included. In 1980s, there were only 1.09% of the total original articles, but in 2000s, 2.63% were RCTs. The mean total Jadad score increased from 1 point in 1980s to 2.17 in 2000s, and the "good quality" trials also increased from 0% to 33.33%. As for the adequate allocation concealment, however, only two studies were observed in 2000s. The most lacking aspect was the appropriate double-blinding. Also, studies intervened by medicine or funded or examined by Institutional Review Boards (IRBs) tended to receive higher quality assessments. Conclusion: Although RCTs consistently increased in quantity and quality, in future studies, researchers should continue to strive towards achieving adequate allocation concealment and appropriate double-blinding. In addition, researchers must become more interested in receiving funds and examination by IRBs.

Background The analysis of the papers on the primary care quality assessment in Korea was performed to summarize existing papers, estimate the level of primary care quality, and suggest the directions and areas of the future research. Methods: Primary care quality-related papers were selected via internet web search engines which were Korean Journal of Family Medicine homepage, KMbase, and KoreaMed. Further papers were added after consultation to primary care quality assessment specialists in Korea. Results: The number of related papers was 29. Data collection was done mostly via mail or telephone questionnaire to suppliers, primary care physicians. Papers on resource capacity area were 11, on services delivery 4, on outcome by service 2, and on clinical performance 12. The total primary care score was low. The themes of clinical performance studies were common diseases in Korea. Conclusion: Research volume on primary care quality assessment was poor, especially on outcome area. Data collection methods and quality indicators are needed to diverse. Future researches using OECD health care quality indicators are needed to make international comparison possible, which fi nally contributes to primary care quality improvement in Korea.

Background Since the Korean Journal of Family Medicine (KJFM) started publishing from 1980, randomized cotrolled trials (RCTs) and non-randomized controlled studies (NRSs) consistently have increased in quality and quantity. Although there have been several studies about the quality assessment of RCTs in Korea, there has been no study about quality assessment of NRS. Thus, this study scrutinies NRS in the KJFM to assess the quantity and quality. Methods: Upon extracting NRSs for assessing a intervention effects from all the articles published in the KJFM from 1980 to 2006, assessments were made on methodological index for non-randomized studies (MINORS). Also the analysis were made upon the proportion of NRSs within original articles according to two categories (comparative study, non-comparative study). The mean scores by research methods and years, and total scores and mean scores of yearly research methods were analyzed. Results: 34 trials on NRSs were selected. In 1980s, 0.65% of the total selected original articles, in 1990s, 1.54%, and in 2000s 5.11% were NRSs. According to the research designs, the mean scores of MINORS were before and after study 8.5, interrupted Time Series 9.7 (out of 16), controlled before and after 13.5, quasi randomized trial 12.6, and non randomized trial 13 (out of 24). Before and after design was the most frequent used (55.9%). Conclusion: Although NRSs consistently increased in quantity, the assessed mean scores were low and most articles used before and after design. Thus, there should be studies using appropriate research methods in the future.

Background : The purpose of this study was to assess the quality of primary care by patient-completed questionnaire, and to investigate whether the results of the assessment were different among the specialties of doctors (especially family medicine) and according to the existence of a family doctor.
Methods : The questionnaire, which covers 7 components of primary care (accessibility, continuity, accountability, comprehensiveness, integration, sustained partnership with patients, whole person orientation), was administered to the applicants of health screening center of a university hospital, and factory workers in Cheonan, and residents living in Seoul. Statistical analysis was performed through the collected samples.
Results : Total of 574 subjects were analyzed. The mean score (%) of each component of the total sample was as follows; accessibility 45.8, continuity 47.8, comprehensiveness 22.5, accountability 55.5, integration 41.8, sustained partnership with patients 48.9, and whole person orientation 31.8. The mean score (%) of all components were 42.0. Doctors were classified into internists, general surgeons, family physicians, general physicians, and others. Family physicians had the best score in accessibility (P=0.01). The mean score of all components of family physicians was better than that of internists and the other specialties (P＜0.05). The number of respondents who had family doctors was 129 (22.5%). The mean score of each component was higher than those without a family doctor (P＜0.05).
Conclusion : Family physicians are providing high quality primary care compared to internists and other specialists. Patients who have a family doctor are provided with higher quality primary care than those who do not. Especially, comprehensiveness and whole person orientation need to be improved.
