Item 4.  Changes in Registrant’s Certifying Accountant.

(a)      Previous Independent Registered Public Accounting Firm.

        On June 10, 2004, the ALARIS Medical Systems Retirement Investment Plan (the "Plan" or the "Registrant") notified PricewaterhouseCoopers LLP that it had engaged Holthouse Carlin & Van Trigt LLP as its independent registered public accounting firm on June 9, 2004, thereby dismissing PricewaterhouseCoopers LLP as its independent registered public accounting firm as of that date.

        The reports of PricewaterhouseCoopers LLP on the financial statements of the Plan for the past two fiscal years did not contain an adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principle.

        In connection with its audits for the two most recent fiscal years and through June 9, 2004, there were no disagreements with PricewaterhouseCoopers LLP on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of PricewaterhouseCoopers LLP, would have caused them to make reference to the subject matter of the disagreements in their reports on the Plan’s financial statements for such years.

        During the two most recent fiscal years and through June 9, 2004, there have been no reportable events (as defined in Regulation S-K 304 (a)(1)(v)).

        The Registrant has requested that PricewaterhouseCoopers LLP furnish it with a letter addressed to the SEC stating whether or not it agrees with the above statements. A copy of such letter is filed herewith as Exhibit 16.1 to this Current Report on Form 8-K.

(b)      New Independent Registered Public Accounting Firm.

        On June 9, 2004, the Registrant engaged Holthouse Carlin & Van Trigt LLP as the new independent registered public accounting firm to audit the Plan’s financial statements as of and for the year ending December 31, 2003.

        During the two most recent completed years ended December 31, 2002 and December 31, 2003 and the subsequent interim period through June 9, 2004, the Plan did not consult with Holthouse Carlin & Van Trigt LLP regarding the application of accounting principles to a specific transaction, either proposed or completed, or the type of audit opinion that might be rendered on the Plan’s financial statements, or any other matters or reportable events as set forth in Items 304(a)(1)(iv) and (v) of Regulation S-K.

Item 7.  Financial Statements, Pro Forma Financial Statement and Exhibits.

(c)      Exhibits.

16.1       Letter from PricewaterhouseCoopers LLP, dated June 16, 2004.
