CDSS availability (in yellow) and usage (in green) in solo primary care practices with physician owners or physician group owners when the reporting location is entirely electronic records based (n=31 833 providers weighted by physician weight of National Ambulatory Medical Care Survey 2015)
| CDSS | Yes, used routinely (%) (1) | Yes, but not used routinely (%) (2) | Yes, but turned off/not used (%) (3) | Used (%) (1+2) | Availability (%) (1+2+3) |
| EREMIND | 89.3 | 4.4 | ~ | 93.7* | 93.7* |
| EIDPT | 74.5 | 2.4 | 3.6 | 76.9* | 80.5* |
| EWARN | 88.4 | 3.5 | ~ | 91.9* | 91.9* |
| EMEDALG | 97.9 | 2.1 | ~ | 100 | 100 |
| EMEDID | 96.6 | 2.1 | ~ | 98.7 | 98.7 |
| ECPOE | 88.6 | 8.5 | 0.9 | 97.1 | 98.0 |
| EGRAPH | 56.1 | 12.4 | 3.3 | 68.5* | 71.8* |
~ indicates no value was reported in the dataset.
*P<0.001 by proportion tests between solo and non-solo practices that are entirely electronic medical record/electronic health record based for each variable. Many measures in solo practices (eg, routine use and availability) are significantly lower than the measures in non-solo practices.
