From: The impact of EHR and HIE on reducing avoidable admissions: controlling main differential diagnoses

  1. The percentages in the Table were calculated out of the total number of admissions. For instance, the percentage of readmissions when medical history was viewed for all DDs: 4.1% is gained as consequence of dividing the number of Readmissions when medical history was viewed (2956) with the total number of admissions in which medical history was viewed (72,689), See at Table 2. All similar percentages were calculated similarly.
  2. *** p<0.001, ** p<0.01, *p<0.05, + p<0.1; n/a not applicable (all similar tables below use the same conventions).
