eClinicalWorks offers a hosted EHR that has been widely adopted in the US.
The company is based in Massachusetts. They boast over 100,000 physicians using their system.
eClnicalWorks is focused on outpatient services only, not currently offering an acute system. They have had success selling into hospitals, offering interfaces between the inpatient and outpatient systems.
While they continue to grow, this could prove to be a weakness for them. Many hospitals systems are electing to implement systems with inpatient and outpatient capabilities, such as Epic or Cerner.
eCW leveraged their standardized pricing and efficient implementation processes in a deal with Sam’s Club. They offered their system for providers, paired with Dell equipment for a fixed price.
The emphasis on a best-of-breed ambulatory product has paid off with many FQHCs and standalone clinics signing with them. Even the NFL announced in 2012 that they were using eClincialWorks for their move from paper to EHR.
