Complementing conventional infectious disease surveillance with national health insurance claims data in the Republic of Korea.

ABSTRACT: Surveillance remains an important tool for timely outbreak detection and response. Many countries, including Korea, have established national infectious disease surveillance systems with clinical notification. We aimed to evaluate the National Health Insurance Claims-based Surveillance (NHICS) compared to conventional passive report-based National Infectious Diseases Surveillance (NIDS). Reported to claimed cases ratios (R/C ratio) were evaluated from monthly notifiable disease cases captured by NIDS and NHICS. The relationships between 26 infectious diseases and each surveillance system were analysed using Pearson's correlation analysis and linear regression. There was an overall increase in R/C ratio from 2010-2017 (0.37 to 0.78). In 22 infectious diseases, there was a correlation between NIDS and NHICS. Moreover, claim-based surveillance showed less fluctuating disease incidence rates than report-based surveillance for specific infectious diseases, such as varicella, mumps, and scarlet fever. However, for infectious diseases with episodic outbreaks or low incidence, it was difficult to assess NHICS usefulness. Claim-based surveillance is less affected by limitations of conventional report-based surveillance systems, such as reporting rate. Given delays in claim systems, a claim-based surveillance is expected to be complementary to conventional systems for the detection of various infectious diseases with the advancement of bio-information technology.

Project description:PurposeThe purpose of the study is to develop an algorithm to identify pregnancies in administrative databases and apply it to assess pregnancy rates and outcomes in women prescribed isotretinoin or tretinoin.MethodsUsing the 2011 to 2015 Truven Health MarketScan Database, we identified pregnancies, including losses and terminations. In a cohort design, nonpregnant women filling a prescription for isotretinoin or tretinoin were matched to five women without either prescription. Women were followed for 365 days or until conception, medication discontinuation, or enrollment discontinuation ("prescription episode"). Rates of pregnancy, risks of pregnancy losses, and prevalence of infant malformations at birth were assessed by exposure.ResultsWe identified 2 179 192 livebirths, 8434 stillbirths, 2521 mixed births, 415 110 spontaneous abortions, 124 556 elective terminations, and 8974 unspecified abortions. There were 86 834 isotretinoin and 973 587 tretinoin episodes, matched to 5 302 105 unexposed women. Pregnancy rates were 3 (isotretinoin), 19 (tretinoin), and 34 (unexposed) per 1000 person-years. Risk of spontaneous pregnancy losses were similar; however, terminations were more common in the isotretinoin-exposed (28% [95% CI: 21%-36%]) than the tretinoin-exposed (10% [95% CI: 9%-11%]) or unexposed pregnancies (6%). Malformations occurred in 4.5% (95% CI: 3.5%-5.6%) of the tretinoin-exposed pregnancies and 4.2% of the unexposed pregnancies (adjusted odds ratio: 1.16 [95% CI: 0.85-1.58]); isotretinoin-exposed births were too few to assess malformations.ConclusionsAdministrative databases can complement risk evaluation and mitigation strategies (REMS) for known teratogens and contribute to safety surveillance for other medications. Here, isotretinoin-exposed pregnancy rates were low, but existent, and many pregnancies were terminated. Tretinoin exposure was not associated with a meaningfully elevated risk of losses or malformations as compared with unexposed pregnancies.

Project description:Objective To measure incidence of early death after discharge from emergency departments, and explore potential sources of variation in risk by measurable aspects of hospitals and patients.Design Retrospective cohort study.Setting Claims data from the US Medicare program, covering visits to an emergency department, 2007-12.Participants Nationally representative 20% sample of Medicare fee for service beneficiaries. As the focus was on generally healthy people living in the community, patients in nursing facilities, aged ≥90, receiving palliative or hospice care, or with a diagnosis of a life limiting illnesses, either during emergency department visits (for example, myocardial infarction) or in the year before (for example, malignancy) were excluded.Main outcome measure Death within seven days after discharge from the emergency department, excluding patients transferred or admitted as inpatients.Results Among discharged patients, 0.12% (12 375/10 093 678, in the 20% sample over 2007-12) died within seven days, or 10 093 per year nationally. Mean age at death was 69. Leading causes of death on death certificates were atherosclerotic heart disease (13.6%), myocardial infarction (10.3%), and chronic obstructive pulmonary disease (9.6%). Some 2.3% died of narcotic overdose, largely after visits for musculoskeletal problems. Hospitals in the lowest fifth of rates of inpatient admission from the emergency department had the highest rates of early death (0.27%)-3.4 times higher than hospitals in the highest fifth (0.08%)-despite the fact that hospitals with low admission rates served healthier populations, as measured by overall seven day mortality among all comers to the emergency department. Small increases in admission rate were linked to large decreases in risk. In multivariate analysis, emergency departments that saw higher volumes of patients (odds ratio 0.84, 95% confidence interval 0.81 to 0.86) and those with higher charges for visits (0.75, 0.74 to 0.77) had significantly fewer deaths. Certain diagnoses were more common among early deaths compared with other emergency department visits: altered mental status (risk ratio 4.4, 95% confidence interval 3.8 to 5.1), dyspnea (3.1, 2.9 to 3.4), and malaise/fatigue (3.0, 2.9 to 3.7).Conclusions Every year, a substantial number of Medicare beneficiaries die soon after discharge from emergency departments, despite no diagnosis of a life limiting illnesses recorded in their claims. Further research is needed to explore whether these deaths were preventable.

Project description:BackgroundFluoroquinolones are one of the commonly used antibiotics for the initial empiric combination treatment. However, there is insufficient evidence to support the use of fluoroquinolones combination therapy for the treatment of hospital-acquired pneumonia (HAP). This study aimed to evaluate the effectiveness of fluoroquinolones as part of the empiric combination therapy for HAP using national health insurance claims data in Korea.MethodsWe compared the clinical outcomes of patients with HAP who received fluoroquinolones combination and those treated with cefepime or piperacillin/tazobactam monotherapy. The primary outcome was hospital mortality, and the secondary outcome was readmission caused by pneumonia as the primary cause of hospitalization within 7 days after discharge from index hospitalization. The association between the combination with fluoroquinolones and outcomes was evaluated with logistic regression analysis.ResultsAmong the 9,955 patients with HAP administered with cefepime or piperacillin/tazobactam, 4,918 (49%) received fluoroquinolones combination. During hospitalization, 1,059 (11%) patients with HAP died. Compared with the monotherapy group, the fluoroquinolones combination therapy group was associated with a higher mortality risk [adjusted odds ratio (OR), 1.30; 95% confidence interval (CI): 1.02-1.65]. After adjusting for potential confounding factors, the association remained significant in the non-high-risk HAP group (adjusted OR, 1.30; 95% CI: 1.02-1.66). Meanwhile, the mortality risk was similar between the fluoroquinolones combination therapy group and the monotherapy group of patients with high-risk HAP (adjusted OR, 0.99; 95% CI: 0.35-1.16). Among the patients alive and discharged (n=8,896), 152 (1.7%) were readmitted within 7 days after discharge. The fluoroquinolones combination therapy group was more likely to be readmitted because of pneumonia than the monotherapy group in patients with high-risk HAP (adjusted OR, 1.60; 95% CI: 1.04-2.47).ConclusionsFluoroquinolones combined with β-lactams was prescribed in nearly half of patients with low-risk HAP, and it was associated with a higher mortality risk in real-world practice. However, it was not associated with hospital mortality even in patients with high-risk HAP.
