PURPOSE: To assess current practice patterns for dry eye patients in South Korea and to evaluate the preference according to the ages and clinic types of physicians. METHODS: Dry eye patients (n = 1,612) were enrolled in this multicenter cross-sectional, observational study. The severity level of dry eye patients was classified based on the Korean guidelines for dry eye treatment. The medical records of the enrolled dry eye patients were evaluated, and the practice styles and the preferences were analyzed according to the ages and clinic types of physicians. RESULTS: Of all patients, dry eye level 1 was most common (47.5%), followed by level 2 (33.5%), level 3 (9.1%), and level 4 (1.1%). Topical anti-inflammatory agents were used in 70.7% of patients with dry eye level 2 and in 80.6% of patients at levels 3 and 4. Topical anti-inflammatory agents were also used in 48.7% of patients with dry eye level 1. Preservative-free artificial tears were preferred at all dry eye levels. The use of topical anti-inflammatory agents did not differ with investigator ages, but older physicians preferred preserved artificial tears more than younger ones. Physicians at referral hospitals also tended to use topical anti-inflammatory agents and preservative-free artificial tears earlier, beginning at dry eye level 1, than those who worked at private eye clinics. CONCLUSIONS: Topical anti-inflammatory agents were commonly prescribed for the treatment of dry eye patients in South Korea, even from dry eye level 1. Preservative-free artificial tears were preferred at all dry eye levels. Practice styles differed somewhat depending on the ages and clinic types of physicians.

Malnutrition is one of the most important factors for the development of nosocomial infection (NI). We performed a study of the correlation between abnormal nutritional factors and NI risk by investigating the patients who stayed longer than 3 days in the intensive care unit (ICU) of our university hospital. The patients were classified into three groups based on serum albumin levels and total lymphocyte counts (TLC). The criteria of Group I (well nourished group) were serum albumin level of 3.5 g/dl or higher and TLC of 1, 400/mm3 or higher. The criteria of Group III (severely malnourished group) were serum albumin of less than 2.8 g/dl and TLC of less than 1, 000/mm3. The other patients were classified as Group II (moderately malnourished group). The occurrences of NI were monitored during the study period and the APACHE III Score was calculated. The probability of first NI infection in Group III was 2.4 times higher than that in Groups I and II. The mortality rate of 20.5% was more significantly correlated with APACHE III Score than nutritional status. Nineteen (53%) of the total 36 NI patients were infected within 10 days after ICU admission and they all belonged to Group III. When we compared the gap period between infections, the time to first infection was significant.
