Are Errors Less Likely with Electronic Prescriptions?

Errors in medical prescriptions occur and a study¹ examined whether electronic prescribing may help reduce errors. Two groups of doctors used written prescriptions and had similar error rates before the study. One group switched to e-prescriptions while the other continued to use written prescriptions, and error rates were measured one year later. The results are given in Table 1.

	Error	No Error	Total
Electronic	254	3594	3848
Written	1478	2370	3848

Table 1 Are prescription error rates different?

Find a 99% confidence interval for the difference in the two proportions, pw-pe, where pw is the proportion of errors using written prescriptions and pe is the proportion of errors using e-prescriptions.

Round your answers to three decimal places.

The 99% confidence interval is Enter your answer; The 99%confidence interval, value 1 to Enter your answer; The 99%confidence interval, value 2.

Is it plausible that there is no difference?

Choose the answer from the menu; Is it plausible that there is no difference?
