Trends in Electronic Health Record System Use Among Office-based Physicians: United States, 2007–2012 [20 May 2014]

Abstract

Objectives—This report presents trends in the adoption of electronic health

records (EHRs) by office-based physicians during 2007–2012. Rates of adoption

are compared by selected physician and practice characteristics.

 

Methods—The National Ambulatory Medical Care Survey (NAMCS) is

based on a national probability sample of nonfederal office-based physicians who

see patients in an office setting. Prior to 2008, data on physician characteristics

were collected through in-person interviews with physicians. To increase the

sample for analyzing physician adoption of EHR systems, starting in 2008,

NAMCS physician interview data were supplemented with data from an EHR

mail survey. This report presents estimates from the 2007 in-person interviews,

combined 2008–2010 data from both the in-person interviews and the EHR mail

surveys, and 2011–2012 data from the EHR mail surveys. Sample data were

weighted to produce national estimates of office-based physician characteristics

and their practices.

 

Results—In 2012, 71.8% of office-based physicians reported using any type

of EHR system, up from 34.8% in 2007. In 2012, 39.6% of physicians had an

EHR system with features meeting the criteria of a basic system, up from 11.8%

in 2007; 23.5% of office-based physicians had an EHR system with features

meeting the criteria of a fully functional system in 2012, up from 3.8% in 2007.

In 2007, a wide gap existed in use of any type of EHR system between

physicians in practices with 11 or more physicians (74.3%) compared with

physicians in smaller practices (20.6% among solo practitioners); the gap,

however, narrowed during 2007–2012. In 2007, no significant gap was observed

in adoption of a fully functional system between primary care (4.7%) and

nonprimary care physicians (2.8%); the gap, however, widened over time (27.9%

compared with 19.4% in 2012). The difference in adoption of a fully functional

system between physicians in practices with 11 or more physicians compared

with solo practitioners was 10.4 percentage points in 2007; the gap widened to

30.6 percentage points in 2012.
