Abstract

Objective. Intentional or unintentional substance intoxications are common in patients presenting to the Emergency Department (ED). When we treat intoxi-cated patients, it is important to know the amount of drug ingestion. We invested the actual amount of semi-quantitative term expressed by patients, and investigated the accuracy of amount estimates by the public and healthcare professionals. Participants and interventions. 200 vol-unteers (86 health care providers and 114 non-practitioners) participated. Partici-pants grabbed the 3 types of tablets (5mm, 10mm, and 15mm) in handfuls and fistfuls and estimated the tablet amounts. Actual amounts were measured. 100 volunteers (58 health care providers and 41 non-prac-titioners) participated in the investigation of accuracy of liquid amount estimation. Participant ingested water in 2.6 cm diam-eter bottle in response to request to take 1 sip, 1 mouthful, and 3 sips.

Results. The estimated tablet counts be-came more accurate in terms of both fist-fuls and handfuls as the size increased within the same shape classification. Par-ticipants tended to underestimate the counts of oval-shaped tablets to a greater extent than round tablets of the same size. The estimated liquids both groups of participants tended to underestimate the amounts but both groups overestimated the volumes when drinking 3 continuous sips. In tablets and liquids, there were no statistically significant differences in accu-racy between the groups.

Conclusions. When approaching intoxi-cated patients who have visited emergency department (ED), treatment should be im-plemented based on the assumption that the actual ingested amounts are higher than the amounts estimated by patients.
