PURPOSE: Since the medical insurance system was started in Korea, there has been an imbalance in the medical charges among the procedural items of special departments. For correcting this problem, the Resource-based Relative Value Scale (RBRVS) was introduced to determine the relative values of physician services and practices. The RBRVS is the prevailing model used today to describe, quantify and reimburse physicians for their services. In this study we attempted to clarify the relative values of the practice characteristics in vascular surgery and evaluate the propriety compared with the relative value unit (RVU) of the American Medical Association (AMA). METHOD: The classification of practice characteristics in vascular surgery was compared with that of the AMA. The propriety of physicians' work was measured according to the Korean and American physicians' work. The rate more than 70, between 50 to 69, and less than 49 were used to decide over-, proper- or under-estimation, respectively. RESULT: The ratio of the number of practice characteristics in Korean and American vascular surgery was 1:3.31 (97:321). The over-, proper- or under-estimated physicians' work among the identical American practice characteristics was 8/46 (17.4%), 19/46 (41.3%) and 19/46 (41.3%) respectively. CONCLUSION: Our results demonstrated that the practice characteristics of Korean vascular surgery are not sorted by detail and a large percentage of physicians' work (41.3%) is under-estimated. Therefore, reasonable payment for physician services or practices can not be determined for Korean vascular surgery.

BACKGROUND: Complex regional pain syndrome (CRPS) is not regarded as an impairment in Korea. Guidelines for rating this impairment are under development by the Korean Academy of Medical Science based on that of the American Medical Association (AMA). However, no studies have been done on the validity of these guidelines in Korea. We therefore evaluated the validity of these guidelines using the criteria from the chapter on the central and peripheral nervous system (CNS-PNS class) and the worksheet for calculating total pain-related impairment score (TPRIS class). METHODS: TPRIS and CNS-PNS classes were calculated through interviews of 28 CRPS patients. The correlation between the two classes was calculated. RESULTS: TPRIS class and CNS-PNS class were well correlated (r = 0.593, P < 0.05). CONCLUSIONS: Both TPRIS or CNS-PNS classes were well correlated and could be used for evaluation of impairment. However, the CNS-PNS class is simpler and quicker to complete.

In 1992 the Korean Medical Association intended to make revised evaluation and rate of physical impairment based upon rate and evaluation of physical impairment according to National Compensation Law which was composed of 14 subdivisions with various rates of physical impairment. Committee of Evaluation of Physical Impairment in Korean Neurosurgical Society provided revised evaluation of nervous or mental impairment, peripheral never impairment and spinal column impairment. Because McBride Disability Evaluation and Guide to the Evaluation of Permanent Impairment by American Medical Association have been used widely in this field the author describe evaluation and rate of physical impairment in each method briefly and compare to revised evaluation by Korean Medical Association in subject of neurologic and spinal impairment.

The American Medical Association's Guides to the Evaluation of Permanent Impairment (Guides) has provided an useful guideline in interpreting information on permanent impairment based on the in-depth knowledge and experience in impairment ratings accumulated for a long period of time. Since its first publication by American Medical Association (1958), as A Guide to the Evaluation of Permanent Impairment of the Extremities and Back', 12 additional guides' has been published by the JAMA over the next 12 years. All the guides were consolidated to become the first official edition of the Guides' in 1971. The 'Guides' has been updated periodically to reflect current scientific clinical knowledge and judgment methods. It has become the best system available to evaluate permanent impairments across many disciplines. The latest sixth edition created a "paradigm shift" in the area of the impairment assessment by introducing a contemporary model of disablement. The standardized methods elaborated in the sixth edition clearly enhances the relevancy of impairment ratings, improves internal consistency of the methods and renders the application of the rating process easier. It adopts the terminology and conceptual framework from the International Classification of Functioning, Disability and Health in order to generate five impairment classes. A diagnosis-based grid has been developed for each organ system. Functional history, physical findings and objective clinical test results are integrated to determine the grade within the impairment class. The Guides' is the most widely used source for assessing and rating permanent impairments in the United States and can be considered as the best available method for the assessment of permanent impairment.

OBJECTIVES: The internet has become an important source of medical information and a great amount of information related to allergic rhinitis (AR) is available on the internet. However, the quality of this information is still a matter of debate. Therefore, this study was conducted to assess the AR-related information on Korean websites. METHODS: The key word "allergic rhinitis" was entered into 4 popular search engines, and this led to identifying 40 websites. After being categorized according to authorship, the informational value of these websites was evaluated using 4 different assessment tools such as the Journal of the American Medical Association (JAMA) benchmarks, the DISCERN questionnaire, the Allergic Rhinitis and its Impact on Asthma (ARIA) 2008 Update and the Health On the Net (HON) code. RESULTS: The 40 websites containing AR-related information were categorized according to their authorship as Western physician: 20, Oriental physician: 14, commercial: 1, and others: 5. The mean citation frequencies of the JAMA benchmarks and the ARIA 2008 Update concepts was 1.23 out of 4 and 4.33 out of 8, respectively, while the mean DISCERN score was 1.92 out of 5. When the websites were evaluated based on the type of authorship, the mean citation frequencies of the ARIA 2008 Update concepts were Western physician: 5.35, Oriental physician: 2.64. Additionally, three websites authored by Western physicians and 13 authored by Oriental physicians contained unreliable information. Among these 16 websites, only 3 websites met the requirements for the HON code "Justification". CONCLUSION: AR-related information available on Korean websites is of variable quality and not all of the information provided is justifiable. Thus, performing surveillance of the medical information on these websites is necessary. Furthermore, common criteria that can be used to evaluate the websites created by both Western and Oriental physicians are also needed.

PURPOSE: The author evaluated the impact of vitreoretinal surgery for proliferative diabetic retinopathy (PDR) on bilateral visual function. METHODS: Anatomic and visual acuity outcomes were reviewed by author for patients who underwent bilateral surgery for PDR. Bilateral visual function was evaluated using the American Medical Association (AMA) Guidelines for Disability scale to quantitate the impact of surgery on visual system disability. RESULTS: There were 18 patients (36 eyes) who underwent vitrectomy for complications of PDR, and the overall anatomic success rate was 100%. Mean visual impairment of the study eyes and visual system according to AMA Guidelines for Disability decreased postoperatively by 22.4% points, and 25.7% points, respectively. A higher functional level of the bilateral visual system resulted postoperatively in 83.2% of all patients, according to eyes with better visual acuity. CONCLUSIONS: Vitreoretinal surgery was associated with a reduction in bilateral visual disability and improved bilateral visual function in patients with PDR.

Nursing language plays an important role in describing and defining nursing phenomena and nursing actions. There are numerous vocabularies describing nursing diagnoses, interventions, and outcomes in nursing domain. However, lack of a standardized, unified nursing language is considered as a problem for further development of the discipline of nursing. With this background this study was conducted to construct a semantic network based on cross mapping of existing nursing terminologies. specifically NANDA taxonomy I, Omaha system, HHCC. and NIC. which arc recognized as standard terminology by the American Nurses Association. The nursing semantic network was proposed with the cross mapping results based on the UMLS semantic network.

PURPOSE: The internet has become one of the most important media outlets used to obtain health information. Therefore, the quality of health information available on the internet is very important. We evaluated the quality of internet-derived health information on allergic rhinitis, rhinitis and sinusitis and compared these results to those of previous studies performed five years ago. METHODS: The terms "allergic rhinitis (AR)", "rhinitis" and "sinusitis" were searched among the four most commonly used search engines in South Korea. These websites were evaluated according to the author, the Journal of the American Medical Association (JAMA) benchmarks, the DISCERN questionnaire and the Allergic rhinitis and its Impact on Asthma (ARIA) 2008 Update. RESULTS: A total of 120 websites were obtained and analyzed. For all diseases, "Oriental physician" had the largest portion (almost half of all websites), followed by "Western physician". Based on analyses using the JAMA benchmark, "Attribution" and "Disclosure" were ignored in almost all surveyed websites. According to the scores of the DISCERN question, the majority of websites did not supply appropriate references for their health information, and information on the negative aspects of treatment such as risks and uncertainty was not provided in several websites. In an analysis based on the ARIA 2008 Update concepts, 65% of websites pertaining to health information on AR contained unreliable information. CONCLUSIONS: The quality of health information on the internet was not acceptable. Thus, governmental regulation or control to improve the quality of health information is required.
