Abstract: Few studies have reported the time spent outdoors in patients undergoing long-term oxygen therapy\n（LTOT）. Also, few have determined whether time spent outdoors was influenced by psychological impairments. The\naim of the present study was to examine the usage of oxygen cylinders to assess the time spent outdoors of patients\nreceiving LTOT, and to evaluate the prevalence of dementia and depressive states and determine the correlation\nbetween these disorders and time spent outdoors. Fifty-four LTOT patients were enrolled in the present study,\nand dementia and depressive states were investigated using specific questionnaires. Among them, 23 patients were\nreassessed one year after the initial evaluation. There was a large variation in time spent outdoors among LTOT\npatients, and the median number was one hour per day. Measured by the Hasegawa Dementia Scale-Revised（ HDS-R）,\ndementia was observed in 41% of the patients. Depressive state, measured by the Self-Rating Depression Scale（ SDS）,\nwas observed in 24%. There were no correlations between time spent outdoors and psychological impairments. The\npercentage of patients in depressive states was statistically higher in the 2nd assessment. More attention must be\ngiven to LTOT patients’ usage of oxygen cylinders, and dementia and depressive state should be periodically assessed.
