The major objective of this research is to identify those hospital characteristics that best explain cost variation among hospitals and to formulate linear models that can predict hospital costs. Specific emphasis is placed on hospital output, that is, the identification of diagnosis related patient groups (DRGs) which are medically meaningful and demonstrate similar patterns of hospital resource consumption. A casemix index is developed based on the DRGs identified. Considering the common problems encountered in previous hospital cost research, the following study requirements are established for fulfilling the objectives of this research: 1. Selection of hospitals that exercise similar medical and fiscal practices. 2. Identification of an appropriate data collection mechanism in which demographic and medical characteristics of individual patients as well as accurate and comparable cost information can be derived. 3. Development of a patient classification system in which all the patients treated in hospitals are able to be split into mutually exclusive categories with consistent and stable patterns of resource consumption. 4. Development of a cost finding mechanism through which patient groups' costs can be made comparable across hospitals. A data set of Medicare patients prepared by the Social Security Administration was selected for the study analysis. The data set contained 27,229 record abstracts of Medicare patients discharged from all but one short-term general hospital in Connecticut during the period from January 1, 1971, to December 31, 1972. Each record abstract contained demographic and diagnostic information, as well as charges for specific medical services received. The "AUTOGRP System" was used to generate 198 DRGs in which the entire range of Medicare patients were split into mutually exclusive categories, each of which shows a consistent and stable pattern of resource consumption. The "Departmental Method" was used to generate cost information for the groups of Medicare patients that would be comparable across hospitals. To fulfill the study objectives, an extensive analysis was conducted in the following areas: 1. Analysis of DRGs: in which the level of resource use of each DRG was determined, the length of stay or death rate of each DRG in relation to resource use was characterized, and underlying pattern of the relationships among DRG costs were explained. 2. Exploration of resource use profiles of hospitals; in which the magnitude of differences in the resource uses or death rates incurred in the treatment of Medicare patients among this study hospitals was explored. 3. Casemix analysis; in which four types of casemix-related indices were generated, and the significance of these indices in the explanation of hospital costs was examined. 4. Formulation of linear models to predict hospital costs of Medicare patients; in which nine independent variables(i.e., casemix index, hospital size, complexity of service, teaching activity, location, casemix-adjusted death rate index, occupancy rate, and casemix-adjusted length of stay index) were used for determining factors in hospital costs. Results from the study analysis indicated that: 1. The system of 198 DRGs for Medicare patient classification was demonstrated not only as a strong tool for determining the pattern of hospital resource utilization of Medicare patients, but also for categorizing patients by their severity of illness. 2. The weighted mean total case cost(TOTC) of the study hospitals for Medicare patients during the study years was $1127.02 with a standard deviation of $117.20. The hospital with the highest average TOTC ($1538.15) was 2.08 times more expensive than the hospital with the lowest average TOTC ($745.45). The weighted mean per total cost (DTOC) of the study hospitals for Medicare patients during the study years was $107.98 with a standard deviation of $15.18. The hospital with the highest average DTOC ($147.23) was 1.87 times more expensive than the lowest average DTOC($78.49). 3. The linear models for each of the six types of hospital costs were formulated using the casemix index and the eight other hospital variables as the determinants. These models explained variable to the extent of 68.7 percent of total case cost (TOTC), 63.5 percent of room and board cost (RMC), 66.2 percent of total ancillary service cost (TANC), 66.3 percent of per diem total cost (DTOC), 56.9 percent of per diem room and board cost (DRMC), and 65.5 percent of per diem ancillary service cost (DTANC). The casemix index alone explained approximately one half of inter-hospital cost variation; 59.1 percent for TOTC and 44.3 percent for DTOC. These results demonstrate that the casemix index is the most important determinant of inter-hospital cost variation. Future research and policy implications in regard to the results of this study is envisioned in the following three areas: 1. Utilization of casemix-related indices in the Medicare data systems. 2. Refinement of data for hospital cost evaluation. 3. Development of a system for reimbursement and cost control in hospitals.

BACKGROUND: Eosinophils are suggested to play a deleterious role in the inflammatory disease of the respiratory mucosa by releasing granule substances such as major basic prorein and eosinophil cationic protein. To investigate the contribution of eosinophils in the pathogenesis of nasal polyps and the mechanism of their accumulation and activation, we observed the eosinophil inhllration and expression of endotjelial and epithelial cell adhesion molecules in the nasal polyp tissues. MATERIALS AND METHODS: Polyp and inferior turbinate mueosal specimens (polyp group) taken out of 20 patients and 10 inferior turbinate mucosa specimens of non-allergic and non-infectious controls (control group) were immunohistochemically stained using EG1, EG2, and mAb for the ICAM-1, VCAM-1 and E-seleetin. The number of EG1 (+) and EG2 (+) cells within lmm2 of tissue and the expression of ICAM-1, VCAM-1 and E-seleetin on the vessels (% of total vessel) and epithelial eelis (area x intensity) were compared among three groups. RESULTS:The inferior turbinate mucosae of nasal polyp patients .were infiltrated by signifieantly higher number of eosinophils (EG1:17, EG2:16/mm2) compared with those of controls (EGi:0, EG2:0/mm2) (p<0.05), and the polyp tissue revealed much more eosinophils (EG1: 213, EG2:154/mm2) than inferior turbinates of same patients and those of controls (p<0.001). ICAM-1 expression in the vessels was frequenly observed both in polyps and in the turbinate mucosae with significant difference (median:85% vs. 67%, p<0.05), and ICAM-1 expression in the epithelial ceils was significantly different between the polyp and turbinate groups (median:9 vs. 2.5, p<0. 01). VCAM-1 was moderately expressed on the vessels of both polyps and turbinate mucosac (median:37%, 14%, respectively) and their expressions were significantly different (p<0.01). E-selectin expression was moderate to low both in the polyps and in the turbinate mucosae (median:18%, 10% respectively) and their expressions were not significantly different (p>0.05). CONCLUSION: Most of the eosinophils infiltrated into nasal tissue as well as nasal polyps were activated forms and they were significantly increased in the nasal polyps compared to the inferior turbinate mueosae of the same patients and control subjects. Significantly increased expression of ICAM-1 and VCAM-1 on the vessels and increased epithelial ICAM-1 expression in the nasal polyps indicate that interactions of eosinophils with ICAM-1 and VCAM-1 participate in the pathogenesis of nasal polyps.

We aimed to investigate the effect of in vitro allergen challenge on activation of eosinophils and expression of intercellular adhesion molecule-1(ICAM-1) in the epithelial and endothelial cells of the nasal mucosa of allergic rhinitics. MATERIALS AND METHODS: Inferior turbinate mucosal specimens which were obtained from 16 perennial allergic rhinitics and sensitized to D. farinae during conchotomy operations were used. Each mucosal specimen was divided into six pieces. The first two pieces were used as basic control group without culture, the second two pieces as culture-control group which was cultured with diluent only, and the last two pieces as antigen-challenge group cultured with D. farinae solution for 24 hours. Specimens were immunohistochemically stained using monoclonal antibody against eosinophil cationic protein(EG1 for all eosinophils and EG2 for activated forms) and ICAM-1. RESULTS: Average counts of EG1 cells and EG2+ cells within 1 mm of lamina propria of nasal mucosa were 14 and 11 respectively in the basic control group, 17 and 19 in culture control group, and 16 and 16 in the antigen-challenge group. ICAM-1 expression on vessels was observed more than half of t,he vessels in the nasal mucosa and there was no significant difference between groups, however, its expression on the epithelial cells was most prominent in the antigen-challenge group (2.1 in basic control group, 3.3 in culture control group, and 6.2 in antigen-challenge group). CONCLUSION: Most of the eosinophils infiltrating into the nasal mucosae out of vessels in allergic rhinitics are activated forms. Significant up-regulation of epithelial ICAM-1 expression by antigen-challenge suggests that ICAM-1 contributes to the transmigration of eosinophils from the subepithelial tissue into the epithelial cell layer and then finally into the nasal secretion.

Five cases of erythema dyschromicum perstans which seem to be the first cases in Korea are described. They are healthy subjects with moderately pigmented skin. Numerous gray-blue macules are seen on the covered part of the body in two patients, but dark brownish macules in other three patients. Histologic findings reveal the characteristic features of hydropic degeneration of the basal cell layer of the epidermis, perivascular infiltrates of lymphocytes and histiocytes and melanin-laden macrophages in the corium in four patients, however, merely pigmentary incontinence into the corium in one patient. We think that there are some problems in cases which show the chracteristic features of erythema dyschromicum perstans histologically but do not have peculiar clinical features, e.g. color of the lesion, especially in Oriental. In this respect, though there may be down for much discussion in three cases which have not typical color of the lesion, we report these cases with typical two cases under the name of erythema dyschromium perstans in order to accumulate more knowledge of these problems

A case of syringoma with unusual distribution in a young healthy woman is reported. Physical examination revealed numerous angular or lichenoid papules, varing from skin color to light brown in hue, on the anterior aspect of the neck, upper chest, breast, sternal area, inframammary area and abdomen with grouping tendency. Some papules had fine scales on their surface. The histologic findings were those of charateristic features of syringoma.
