Providers' selections of electronic health record systems tend to vary by physician practice size, according to a survey by AmericanEHR Partners, Becker's Health IT & CIO Review reports.

The survey -- conducted between Jan. 1, 2013, and Nov. 6, 2014 -- yielded responses from about 1,400 clinicians (Jayanthi, Becker's Health IT & CIO Review, 5/20).

Findings on EHR System Selection

According to the survey, large practices tended to select EHR systems from a limited pool of products, compared with smaller practices (Durben Hirsch, FierceEMR, 5/18).

Specifically:

• 60% of respondents from practices with 26 or more clinicians reported using one of just 10 different EHR systems; and
• 51% of respondents from practices with one to three clinicians reported using one of 10 EHR systems (Pearson, Clinical Innovation & Technology, 5/21).

According to Shari Erickson -- senior vice president of the division of governmental affairs and medical practice of the American College of Physicians, which co-founded AmericanEHR Partners -- the 40% of larger practices that used an EHR system other than the top 10 were spread out among 86 vendors.

Top Vendors

Overall, the two top vendors were:

• Epic, with 14% of the market share; and
• Allscripts, with 9% of the market share (FierceEMR, 5/18).

Meanwhile, the top vendors among practices with one to three clinicians were:

• Practice Fusion, with 15% of the market share among solo practices and 12% among those with up to three clinicians;
• eClinicalWorks, with 9% of the market share among both solo practices and those with up to three clinicians;
• Epic's ambulatory EHR system, with 5% of the market share among both solo practices and those with up to three clinicians; and
• Amazing Charts, with 5% of the market share among solo practices (Lowes, Medscape, 5/20).

Epic's ambulatory EHR system was the top product among practices with:

• Four to 10 clinicians, with a 14% share;
• 11 to 25 clinicians, with 25%; and
• 26 or more clinicians, with 16% (Becker's Health IT & CIO Review, 5/20).
