We have previously showed that routine screening of all patients with acute poisoning for salicylates in Hong Kong is unnecessary. We suggested that plasma measurements should be restricted to those suspected of having ingested salicylates. Our results and suggestion have since been presented and discussed in our medical unit meetings. ⋯ In 172 patients (88%), ingestion of salicylates was not suspected; 3 (1.7%) had plasma salicylate concentrations of 0.47-2.05 mmol/L but mild symptoms only. We confirmed that routine screening for salicylates in all patients with acute poisoning was unnecessary. Despite our suggestion, 88% of plasma salicylate measurements in this follow-up study (76% in January 1992-June 1993) involved patients not suspected of having ingested salicylates.
