Pro Re Nata Prescription and Perception Difference between Doctors and Nurses / 가정의학회지

BACKGROUND: Pro re nata (PRN) prescription is a frequently used prescription method in hospitals. This study was conducted to investigate actual condition of PRN prescription and whether administration error occurred because of perception difference between doctors and nurses. METHODS: From May to July 2012, a survey was conducted among 746 doctors and nurses (88 doctors and 658 nurses) working at 5 hospitals located in Seoul, Gyeong-gi, and Gangwon Province. Doctors generating PRN prescription responded to actual conditions of PRN prescription and both doctors and nurses reported whether administration error occurred due to perception difference. RESULTS: Average number of PRN prescription of surgical residents was 4.6 +/- 5.4, which was larger than that of medical residents (1.7 +/- 1.0). Surgical residents more frequently recorded maximum number of daily intake (P = 0.034) and, although not statistically significant, more often wrote exact single dosage (P = 0.053) and maximum dosage per day (P = 0.333) than medical residents. Doctors expected nurses to notify them before the administration of medication; however, nurses were more likely to conduct PRN administration by their own decision without informing doctors. In addition, some doctors and nurses experienced administration errors because of it. CONCLUSION: Standard prescription methods need to be established since there is a perception difference in PRN prescription between doctors and nurses and this could be related to administration errors.

Recurrent Atopic Myelitis Presenting as an Isolated Lhermitte's Sign / 대한임상신경생리학회지

Atopic myelitis (AM) is a relatively mild form of myelitis associated with allergic diathesis, and present with predominant sensory manifestations. Lhermitte's sign has been considered as a relatively non-specific clinical sign suggesting demyelinating lesion in cervical cord. Here we report a patient with recurrent AM who presented with isolated Lhermitte's sign, both in first and second attacks. This report suggests that either the diagnosis or recurrence of AM can be frequently underdiagnosed because of its predominant sensory manifestations.
