Incorrect Data in Table and Text: In the Original Contribution entitled “Emergency Department Use and Subsequent Hospitalizations Among Members of a High-Deductible Health Plan” published in the March 14, 2007, issue of JAMA (2007;297:1093-1102), the third and fifth columns of Table 4 contained miscalculated data. The corrected table appears below. In addition, the third and fourth full paragraphs on page 1098 of the article should read as follows:
“Table 4 shows utilization patterns by deductible level.
The percentages of HDHP members in individual/family plans who had deductibles of $500/$1000, $1000/$2000, and $2000/$4000 were 9.9%/23.3%,
13.9%/32.3%, and 6.2%/14.3%, respectively. Of members in individual HDHPs, 32.2%, 19.8%, and 5.7%, respectively, of members with $500,
$1000, and $2000 deductibles exceeded their deductible during the follow-up period. For those in family plans, 41.4%, 19.4%, and 8.5%,
respectively, of members with $1000, $2000, and $4000 deductibles exceeded their individual or family deductible. Eighty-four percent of all emergency department visits by HDHP members in the follow-up period and 90% of first visits occurred while members were below their deductible level.
There was little difference in the odds of a visit in the follow-up period compared with the baseline period by deductible level. However,
members in individual plans whose spending exceeded the deductible level had a statistically significant higher odds of visiting the emergency department compared with the odds during time spans when members remained below deductible levels (odds ratio, 1.8;
95% CI, 1.4-2.4), with the highest odds of emergency department visits among members with $2000 deductibles (odds ratio, 2.9; 95% CI, 1.1-7.7).
Members of family plans showed similar patterns of utilization after reaching their deductible level compared with members in individual plans.”
