Item 8.01 Other Events.

      On February 10, 2005, NextGen Healthcare Information Systems, a subsidiary
of Quality Systems Inc., announced its entry into an agreement with Siemens
Medical Solutions. Under the terms of the agreement, Siemens will add NextGen
Healthcare's EMR and Practice Management Solutions to its global solutions
portfolio. A copy of the press release announcing the agreement is attached
hereto as Exhibit 99 and is incorporated herein by reference.

      The press release contains forward-looking statements within the meaning
of the federal securities laws. Statements regarding future events,
developments, NextGen's future performance, as well as management's
expectations, beliefs, intentions, plans, goals, estimates or projections
relating to the future (including, without limitation, statements concerning
NextGen's opportunity and ability to significantly accelerate its expansion into
international markets and additional domestic markets), are forward-looking
statements within the meaning of these laws and involve a number of risks and
uncertainties. Moreover, these forward-looking statements are subject to a
number of risks and uncertainties, some of which are outlined below. As a
result, actual results may vary materially from those anticipated by the
forward-looking statements. Among the important factors that could cause actual
results to differ materially from those indicated by such forward-looking
statements are: the ability of NextGen and Siemens to deliver and maintain
interoperable solutions; the possibility that these solutions will not achieve
or sustain market acceptance; the timing, cost and success or failure of new
product and service introductions, development and product upgrade releases;
undetected errors or bugs in software; changing economic, political or
regulatory influences in the health-care industry; availability of third-party
products and components; competitive pressures including product offerings,
pricing and promotional activities; general economic conditions; and the risk
factors detailed from time to time in Quality Systems' periodic reports and
registration statements filed with the Securities and Exchange Commission.
Quality Systems undertakes no obligation to publicly update any forward-looking
statements, whether as a result of new information, future events or otherwise.
