I recently encountered a patient fall partially r/t hospital door not alarmed. Patient was an 86 y.o. female who's POA was activated & experiencing D.T's from ETOH withdrawal. Pt attempted to get out of bed every 10-15 min. even after receiving Librium and ,Lorazepam as per hospital protocol. The Tech forgot to turn on her bed alarm before leaving her room. 10 minutes later patient walked down hall,passed thru 2 hospital doors (which weren't armed). Pt was found by the tech,who heard the patient yell outside the door lying on the ground. Patient had only a laceration on elbow. When I called maintenance as to why the alarm wasn't on the door, he said it depends if the alarm toggle switch was in the ON position. When I looked @ the panel & said no lights were on- either yellow or red - his response was " Not all the lights work anyway. You'll have to open the door to see if its alarmed. Had the door been alarmed, the patient wouldn't had fallen or gotten outside. Manager said it was nursings fault & not maintenance. What are your opinions?
