Background: We experienced the earthquake and Tsunami in northeast Japan 3 years ago. We never had enough natural resources, but are an enormous consuming society. Because of the influence of the atomic energy plant shutdown and reflection, we began to save more electricity and turn off air conditioners even in hot humid summer in Tokyo. We are working at a pharmacy next to a diabetes clinic. We felt the necessity to discuss with our patients the preparation of their drugs in case of disasters. Method: We administered a questionnaire in August 2011 asking about their preparation and preservation of their drugs and medication lists of their own. 421 answered (98.6%). Male 232, female 189, average age, 58.9 (SD: 15.0), duration of insulin injection, 7.1 (7.1) years, HbA1c, 7.3 (1.2)%. Result: (1)Where they kept new unopenedmedicine; themost (81.1%) frequent answer was “in the refrigerator”, however, 16.1% was “in the room”. “In the room” patients tended to have the illness longer (p< 0.05 by Wilcoxon test), and older (p = 0.07). (2) Where they kept opened medicine; 77.8% answered “in the room”, and 10.8% answered “in the refrigerator”. Between the two groups, age and length of illness was not significantly different, but GLP-1 and only basal insulin injection patients tended to store in the refrigerator (p< 0.01 by chi-squire test). (3) How they carried medicine when went out; 72.1%, “in the bag”, and 20.3% answered that they “don’t carry injection drugs”. The “don’t carry medicine” group mostly injected GLP-1 or basal insulin only, still 12 patients injected pre-mixed insulin 3 times a day. (4) How often they changed needles; 87.1% answered “every time”, on the other hand, 12.9% answered “changed occasionally” and “using the same needles constantly”. (5) The troubles during injection; 8.3% answered “big bubble in the liquid”. 6 out of 33 were injecting GLP-1. (6) Preparation of the bags whenmedicine was carried outside in an emergency was 55.2%. They tended to be female (p< 0.01), there were no relationships to age, nor duration of injection. (7) 8.2% put injections into an emergency bag. They rotated the drugs every10 days to 5 months. (8) Carrying a medication list in a pocket size notebook we handed out; 26.7% answered that they always did. They were older (p< 0.01). Conclusion: GLP-1 patients kept already opened pens in the refrigerator and experienced gas bubbles more. Comparing with insulin, less frequent injection and differences of devices can be the cause. Who were older and have been injecting longer tended to be unsure about preservation of injection medications. Because of today’s hot weather in Tokyo, even already opened injection devices probably should be kept in a refrigerator (We used to tell our patients not to put an opened device in a refrigerator to protect the precision of the device). We may have to advice patients to check the temperature of their rooms and to carry insulation tools such as small bags. We also recognize the skipping of injections when patients go out. The patients who frequently inject (supposed to be more insulin-dependent) did not always prepare for an emergency. We should advice the necessity of the “emergency bag” and also about storing insulin in many places to access easily. Carrying “medication list” rate was still lower than we expected. We have to convince them of the usability of it in reality of the last disaster. We also have to consider more convenient and easy ways of sharing medication information.
