The table above gives information for 2011 on vendors, installations, and associated usability ratings for 10 types of Enterprise Electronic Medical Record (EMR) systems. In addition to total installations and the number of adverse events, the table also gives the percent change in the total installations and adverse events from 2010 to 2011 and the rank of the EMR for total installations. The table also includes the number of the adverse events that were preventable and the number that were fatal.

Consider each of the following statements about EMRs. For each statement indicate whether the statement is supported based on the information provided in the table.

Apt0810 · Answer

1)No, since Cerner having second greatest number of installations doesn't have both the third greatest number of adverse
events and the lowest number of fatal adverse events.
2)Yes,since change is -6.1% and Value in 2011 is 185, so value in 2010 is ~ 197
3)Yes,since Healthland is having second greatest decrease installations and here the ratio of preventable to fatal is 4590/45 = 102/1
4)Yes,since Healthland is having ninth rank in total installations,with a reduction in total number of adverse events (-ve % per the graph) and lowest in terms of the number of fatal adverse events

1) No, 2nd greatest number of installations: Cerner. Since Cerner doesn't have both the third greatest number of adverse
events and the lowest number of fatal adverse events, the Answer is NO.
2) If you multiply 197*(1-6.1%) is aproximately (you can estimate 6% of 200 which is 12) 185. Answer is YES
3) Second greatest percent decrease in total installations from 2010 to 2011: Healthland. the ratio is 4590/45 which is 102:1. Answer YES
4) The EMR that ranks ninth in total installations: Healthland. Since the % change is negative, they reduced the amount of adverse events and they still rank 2nd. Answer YES
