An error occurred when calculating the values for the rows “Quasi-experimental literature (lower-bound point estimate from literature),” “Percentage change relative to overall demand,” “Quasi-experimental literature (upper-bound point estimate from literature),” and “Percentage change relative to overall demand” in Table 4, and as a result the values and percentages in the text on page 81 are erroneous. This was noticed following publication in the March 2014 issue of The Milbank Quarterly.
Table 4 is reproduced below with the correct data in bold.
On page 80, the text in the last paragraph should read:
Table 4 summarizes these results. With respect to inpatient stays, 3 of the 4 scenarios suggest expected increases in demand, ranging from 0 to 1.2 million stays per year (0 to 4.13% of aggregate utilization). But if the newly insured respond in the same way as the privately insured do, inpatient stays are predicted to fall slightly. ED visits also show considerable variation. Two scenarios suggest a drop in ED visits, and 2 scenarios suggest an increase. All 4 scenarios indicate a positive demand response with respect to office-based visits and suggest an increase of between 3.8 million and 52.3 million additional visits per year (a 0.25% to 3.4% increase from current baseline levels overall). Finally, with respect to prescribed medicines, the smallest and largest predicted effects suggest the possibility of no demand response to a 6.4% increase in overall utilization.
The author regrets any inconvenience caused by these errors.
