Antibiotics are used for the prevention and treatment of infections. This study aimed to investigate the patterns of dental antibiotic prescription in children and adolescents. The Health Insurance Review and Assessment Service provided data on patients who visited medical institutions. It was categorized according to year, sex, age, insurance type, dental institution, and region. Chi-square tests, Fisher's exact tests, and one-way analyses of variance were performed. Statistical analyses were performed using SAS software (ver. 9.2; SAS Institute, Cary, NC, USA). Amoxicillin and cephalosporins, the most commonly used antibiotics, accounted for approximately 96% of the prescriptions. The younger the child, the more antibiotics were prescribed for trauma, pulpitis, and dental abscesses. However, closer to adolescence, the antibiotics were primarily prescribed to manage impacted teeth and periodontal problems. Antibiotics were prescribed for 3.13 days on average. There were significant differences in the prescription rates according to age, sex, type of insurance, type of medical institution, and region (p < 0.05). This study suggested that antibiotic prescriptions should be closely monitored to ensure appropriate usage of antibiotics.

The rate of antibiotics prescription for an acute airway infection significantly varies depending upon the diagnosis type, specialty, and the location of the hospital along with many other related factors. The objective of this study is to empirically investigate the possible relationship between the antibiotics prescription rates for an acute airway infection and the degree of competition in the hospital market regions of mainly the providers of primary medical care services such as clinics, internal medicines, pediatrics and otorhinolaryngology department. Using the data from Health Insurance Review and Assessment Service (HIRA) regarding the hospitals' antibiotics prescription rates for the acute airway infection and controlling for selected variables of demand and supply sectors, this study tries to figure out that the degree of competition in the hospital market, regardless of what type of competition indexes we employed, has a statistically significant effect on the variations of antibiotics prescription rate of the clinics in local areas. This result implies that as an economic consideration itself, the change in the degree of competition in the hospital market can play a crucial role influencing the treatment behaviors of the medical doctors. More specifically, this study reveals that as the degree of competition increases the antibiotics prescription rate goes up. This result means that if the market becomes more competitive in a specific region so that it might cause a reduction in doctor's income, doctors with rational decision-making process, recognize that the benefit created from inducing patients' seemingly unnecessary demand for medical care (income effect) would be higher than the costs associated with sustaining their targeted income (substitution effect). It is because that the doctors are more likely to prescribe antibiotics which create relatively higher margins than other medical care services in order to sustain their targeted income when the hospital market competition becomes tighter. Even though this study empirically confirms that antibiotics prescription can be affected by the economic incentives, it still raises following issues as limitations of the study: first issue is about the representativeness of the hospital regions segregated for this study, which might be weak in explaining whether these regions are mutually exclusive in reality. Patients actually consider the quality of services, transportation cost, time costs, and any other related factors choosing the doctors or hospitals, and in that sense, this study rules out 'border-crossing' in using the medical care services. Second issue arises in capturing the data of antibiotics prescription rate. Since we use the average rate for each medical institution, we cannot figure out the average rate for each patient so that we are not able to control for the variation of patients' medical conditions. It is because of the unavailability of data regarding each patient's medical condition from HIRA. Thirdly, since this study mainly analyzes the medical institutions providing primary care such as clinics, internal medicines, pediatrics, and otorhinolaryngology department, it is skeptical of whether those institutions can represent the hospital market in respective regions and truly reflect the degree of competition. It needs to extend the study areas and disease types as well as any micro data for future studies.

과거 한국의 식품 오염원 중 법적인 규제 등을 통해 구체적인 통제가 이루어지지 못하고 있는 것이 축산물의 항생제로 알려져 항생제 오 남용으로 인한 내성균의 출현으로 비상이 걸렸던 적이 있었다. 요즘은 항생제를 지나치게 많이 사용해 가축이나 인체 내의 병원성 미생물들이 내성이 생겨 문제가 되고 있어 2011년 7월부터 가축용 사료에 항생제 첨가가 금지하게 된다. 한국은 항생제 내성률 1위로, 2000년 세계보건기구(WHO)에 따르면 대표적 항생제인 페니실린에 대한 폐렴구균의 내성률이 70%로 세계 1위이다. 어느 보고서에 따르면, 축산물 1톤을 생산하는 데 사용되는 항생제가 스웨덴이나 뉴질랜드, 덴마크 등 축산 선진국이 31~44g에 불과한데 비해 한국은 911g에 이른다. 투여 경로는 배합사료에 포함된 양이 54%, 농가의 임의 치료가 40%, 수의사 처방은 겨우 6% 순으로 나타났다. 그러나 OECD 회원국 중 수의사 처방 없이 항생제의 임의 투여를 허용하고 있는 나라는 한국뿐이다. 세계보건기구(WHO)에서는 가축사료에 항생제를 첨가하지 말 것을 권장하고 있으며, 유럽연합(EU)도 항생제는 반드시 수의사의 처방에 의해서만 사용토록 제한하고 있다. 최근 국립수의과학검역원에 의하면, 축산용 항생제 사용량이 2008년에 비해 18%, 2001년에 l해 무려 38%가 감소되었으며, 이중 닭은 20%, 소의 항생제 사용량은 36%가 감소하였다고 밝혔다. 사육 가축들의 항생제 오남용을 줄이기 위해서는 사료에 첨가하는 항생제나 성장호르몬, 비소 투여 등의 투여 대신에 미생물 생균사료나 녹차사료, 한약재사료 등의 천연면역물질을 함유한 사료를 먹여 스트레스를 덜 받고 면역력 증강에 좋은 사료를 먹여 키운 건강한 가축으로 생산한 육류는 맛도 특별히 좋다. 본 자료의 대부분은 금년부터 3년간 농촌진흥청 국립축산과학원과 중국청도농업대학과 "고품질 축산물생산을 위한 중약제를 이용한 질병방지체제 연구"라는 과제로 공동협력연구를 수행하게 됨에 따라 지난 11월 4일부터 10일까지 필자가 중국 청도농업대학을 방문하여 세미나시 발표한 자료임을 밝혀두며, 국내 수의학 연구에도 도움이 되고 저 소개한다.

This study investigated the medicines prescribed in dental services in order to provide information and materials on dental clinics and hospitals, for the intention of leading the dental circle to make efforts for voluntary improvement, do adequate prescription, and attempt for bench marking through this unfolding of their tendency in continuous prescription behaviors, and leading the people to have a right recognition on adequate medicine use through this information on their medicine-taking behaviors including antibiotics and injections. From the records of outpatient prescriptions of medicines under health insurance over the period of June 1st to September 31th in 2003 in the 34,226 recuperation institutions, antibiotics and injections were analyzed into administration days, prescription frequency, medicine cost per administration day, the number of medicines per prescription, and the number weight of high priced medicines. The findings were as below: 1. Adminstration days of antibiotics was 90.11% in the dental clinics, which was a decrease than the same quarter and the previous quarter of the previous year. While the prescription frequency of antibiotics was 15.5%, higher than the same quarter and the previous quarter of the previous year. In dental hospitals, administration days and prescription frequency of antibiotics were 71.57% and 21.05%, respectively, a little higher than the previous quarter. Compared to other kind of recuperation institutions, dental clinics and hospitals had higher administration days and lower prescription frequency. 2. For injections, adminstration days and prescription frequency in dental clinics were 0.13% and 0.05%, respectively, which were decreases than the same quarter of the previous year. In dental hospitals, adminstration days and prescription frequency were 1.03% and 0.88%, respectively, a little lower than those of the previous quarter. Compared to other kind of recuperation institutions, dental clinics and hospitals were very lower in injection administration days and injection prescription frequency. 3. The number of prescribed medicines was 2.79 in the dental clinics, which was lower than the same quarter of the previous year but higher than the previous quarter. Dental hospitals put 2.67 numbers of medicines per prescription, an increase than the same quarter of the previous year and the previous quarter. Compared to other kind of recuperation institutions, dental clinics and hospitals put smaller number of medicines per prescription. 4. Medicine cost per administration day was 863 won in the dental clinics, which was an increase than the same quarter of the previous year and in the previous quarter. Compared to other kind of recuperation institutions, dental clinics and hospitals had lower medicine cost per administration day. 5. The number weight of high priced medicines was 46.43% in dental clinics, which was an increase than the previous quarter. In dental hospitals, it was 54.05%, so remarkable an increase than the previous quarter. Compared to other kind of hospitals and clinics, dental clinics and hospitals prescribed larger number of high priced medicines. 6. By districts, the frequency of antibiotics prescriptions was the highest in Kwanju and the lowest in Daejeon. The frequency of injection prescriptions was high in all Youngnam districts as was in the second quarter, while low in all the Metropolitan districts. There was a large variation in the prescription frequency to the districts, as the district of the highest prescription frequency had more than 2 times larger frequency than the district of the lowest frequency. Medicine cost per administration day was the highest in Ulsan but the lowest in the north part of Cholla province. The number of medicines per prescription was the largest in Kyonggi province while the smallest in Cheju-do.

This study analyzes the impact of competitions clinics on the total treatment cost and anti-biotics prescription rate. The result of implementing the basic statistics, correlations, and regression analysis by facilitating the evaluation data by Health Insurance Review & Assessment Service in 2015 for acute otitis media in children is shown as follows. First, there is a significant difference for each si-gun-gu for the competition index between total treatment cost and clinics, but there is almost no significant difference for the anti-biotics prescription rate. Second, competition in clinics has statistically important impact on the total examination cost And, third, competition in clinics has no statistically important impact on the anti-biotics prescription rate. There is a need for additional studies on re-examination rate, treatment cost per visit and so forth in order to clarify other factors of competition for medical institutions impacting on the physician behavior in the future studies.

Purpose: Because children with asplenia have an increased risk of fulminant infection associated with a high fatality, chemoprophylaxis, and vaccinations against encapsulated bacteria are recommended. However, there have been few reports of the burden of severe bacterial infection and the current status of chemoprophylaxis and immunization among children with asplenia in Korea. Methods: We conducted a retrospective study including children with asplenia who were treated at our institute between January 1997 and December 2016. Results: From a total of 213 children with asplenia, 114 (53.5%) had congenital asplenia and 58 (27.2%) had functional asplenia. The remaining 41 (19.3%) had acquired asplenia with the median age at splenectomy being 12.2 years (range, 5.0 to 16.9 years); the most common cause of splenectomy was hereditary spherocytosis (39.0%). The chemoprophylaxis rate was 16.4%. The immunization rates were 44.1% for pneumococcus, 53.0% for Haemophilus influenzae type B, and 10.7% for meningococcus. The incidence of invasive bacterial infection among children with asplenia was 0.28/100 person-year; a total of six episodes (2.8%) were observed in five patients with congenital asplenia and one patient with functional asplenia. The median age for these infections was 15 months (range, 4 to 68 months). Five of the six episodes were bacteremia, and the other was meningitis. The most common pathogen was Streptococcus pneumoniae (n=3), followed by H. influenzae (n=1). Three of the six patients (50.0%) died, all of whom had pneumococcal bacteremia. None of the six had chemoprophylaxis or proper vaccinations. Conclusions: Although there is an increased risk of a severe infection proper vaccinations and chemoprophylaxis are still lacking. Physicians should be encouraged to implement appropriate chemoprophylaxis and immunizations for patients with asplenia.

This study was conducted to investigate the changes in patients and medical services before and after the Separation of Prescription and Dispensing in Health Center. For the purpose of this study, prescription data of 5,890 prescribed patients in March 2000(before the Separation of Prescription and Dispensing) and 3,496 prescribed patients in March 2001(after the Separation) in 4 Health Centers located in Gyeongsangbuk-do and Gyeongsangnam-do were collected. For investigation of the change of character of prescribed patients and the disease, sex, age, chief diagnosis, the hind of medical insurance, days of visit, days of prescription were investigated by using National Health Insurance claim data. And for investigation of change of prescription, prescribed drugs per each claim, the use rate of antibiotics, injection, and high-price antiphlogistic drug were investigated for acute respiratory disease and musculoskeletal disease. The major results were as follows: For the changes of prescribed patients of each disease, patients with acute respiratory disease were decreased by 49.7% after the Separation of Prescription and Dispensing than before the Separation of Prescription and Dispensing and patients with hypertension(18.1%), patients with musculoskeletal disease(70.5%), patients with diabetes(8.5%), patients with digestive organ disease(71.2%), patients with chronic respiratory disease(76.4%) were decreased. But patients with urethritis were increased by 66.7%. The mean Health Center visited days of prescribed patients decreased significantly after the Separation of Prescription and Dispensing than before in both male and female(p<0.01) and in health insurance patients(p<0.01). For the each of the disease, hypertension, diabetes, musculoskeletal disease decreased. The mean prescribed days increased after the Separation of Prescription and Dispensing than before(p<0.01). According to the kine of disease, the mean prescribed days increased after the Separation of Prescription and Dispensing than before in all the diseases except the urethritis(p<0.01). For acute respiratory diseases, number of prescribed drugs per each claim decreased significantly after the Separation of Prescription and Dispensing(4.7 drugs) than before(4.9 drugs) and the prescription rate of injection decreased significantly from 63.8% to 7.70%, and the prescription rate of antibiotics decreased significantly from 337% to 19.1%(p<0.01). For musculoskeletal diseases before and after Separation of Prescription and Dispensing, number of prescribed drugs per each claim decreased significantly from 3.7 to 3.2 and the prescription rate of injection decreased significantly from 64.9% to 1.7%, and the prescription rate of high-price antiphlogistic drugs increased significantly from 29.1% to 397%(p<0.01). In consideration of above findings, the mean visited days decreased and on the contrary, the mean prescribed days per each prescription increased after Separation of Prescription and Dispensing than before in health centers. For the prescription pattern of physicians, number of prescribed drugs and the prescription rates of injection and antibiotics per each claim decreased, but the prescription rate of high-price antiphlogistic drugs increased after Separation of Prescription and Dispensing.

Controlling inappropriate antibiotics prescribing for acute upper respiratory infections(URI) is a very important for prudent use of antibiotics and resistance control. Health Insurance Review and Assessment Service (HIRA) introduced Prescribing Evaluation Program and publicly reported antibiotics prescribing rate for URI of each health institution. We performed segmented regression analysis of interrupted time series to estimate the effect of public report on antibiotics prescribing rate using national health insurance claims data. The results indicate that just before the public report period, clinics' monthly antibiotics prescribing rate for URI was 66.7%. Right after the public report, the estimated antibiotics prescribing rate dropped abruptly by 12.3%p. There was no significant changes in month-to-month trend in the prescribing rate before and after the intervention.
