Are diagnostic testing and admission rates higher in non-English-speaking versus English-speaking patients in the emergency department?
OBJECTIVE
To determine whether non-English-speaking patients who present to an emergency department have more diagnostic tests ordered, higher admission rate, and longer length of stay in the ED than English-speaking patients for 2 common complaints, chest pain and abdominal pain.


METHODS
This prospective, comparative, observational study was conducted at a public hospital ED. The study group was composed of 324 patients (172 non-English-speaking and 152 English-speaking) presenting with nontraumatic abdominal pain (148) or chest pain (176). The main outcome measures were admission rates, length of stay in the ED, and diagnostic test and procedure ordering.


RESULTS
The mean age for the total sample was 45.8+/-15.5 years (range 14 to 87 years); 45.4% (147/324) of the patients were male. For the non-English-speaking patients, the language distribution was Spanish (31.0%), other (9.0%), Cantonese (5.9%), Hindi (2.5%), Mien (1.5%), Arabic (1.9%), Russian (0.9%), Mandarin (0.6%), and Korean (0.3%). The admission rate was 37.8% for English-speaking patients versus 42.8% for non-English-speaking patients in the total sample (mean difference in proportions 5%, 95% confidence interval [CI] -6% to 16%; 34.2% for English-speaking versus 9.1% for non-English-speaking patients presenting with abdominal pain, mean difference in proportions 5%, 95% CI -11% to 21%) and 40.9% for English-speaking versus 45.8% for non-English-speaking patients presenting with chest pain (mean difference in proportions 5%, 95% CI -10% to 20%). Power was 80% to detect a 15% difference in admission rates at an alpha value of.05. There was no statistically significant difference in ordering of diagnostic tests between the non-English-speaking and English-speaking patients with chest pain. Non-English-speaking patients with abdominal pain had 5 tests ordered more often than English-speaking patients. The mean difference in proportions (with 95% CIs) for these tests were CBC count 18.4% (5.1% to 31.7%), serum electrolytes 17.9% (3.8% to 31. 9%), urinalysis 20.0% (4.5% to 35.6%), ECG 23.4% (8.6% to 38.2%), and abdominal computed tomographic scan 10.9% (1.0% to 20.8%). There was no statistically significant difference between English-speaking and non-English-speaking patients for ED length of stay in the total sample (mean difference 29.8, 95% CI -37.5 to 97.1 minutes; for the abdominal pain subgroup, mean difference 19.5, 95% CI -74.6 to 113.5 minutes; and for the chest pain subgroup, mean difference 37.9, 95% CI -58.0 to 133.8 minutes).


CONCLUSIONS
Significantly more tests are ordered for non-English-speaking patients with abdominal pain in the ED, including 3 times as many abdominal computed tomographic scans. There is no increase in test ordering with non-English-speaking patients with complaints of chest pain in the ED. When comparing English-speaking and non-English-speaking patients, there were no statistically significant differences in admission rates or length of stay in the ED.
