Report of Independent Registered Public Accounting Firm

To the Plan Administrator of the
ALARIS Medical Systems Retirement Investment Plan:

We have audited the accompanying statements of net assets available for plan benefits of ALARIS Medical Systems Retirement Investment Plan (the “Plan”) as of December 31, 2003, and the related statement of changes in net assets available for plan benefits for the year ended December 31, 2003. These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements based on our audits. The financial statements of ALARIS Medical Systems Retirement Investment Plan as of December 31, 2002 were audited by other auditors whose report dated June 26, 2003, expressed an unqualified opinion on those statements.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principals used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion.

In our opinion the financial statements referred to above present fairly, in all material respects, the net assets available for plan benefits as of December 31, 2003, and the changes in the net assets available for plan benefits for the year ended December 31, 2003 in conformity with accounting principles generally accepted in the United States of America.

Our audit was performed for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule, as listed in the accompanying index, is presented for the purpose of additional analysis and is not a required part of the basic financial statements, but is supplementary information required by the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. The supplemental schedule is the responsibility of the Plan’s management. The supplemental schedule has been subjected to the auditing procedures applied in the audit of the basic financial statements and, in our opinion, are fairly stated in all material respects in relation to the basic financial statements taken as a whole.

ALARIS MEDICAL SYSTEMS RETIREMENT INVESTMENT PLAN

Notes to Financial Statements


NOTE 1 - DESCRIPTION OF PLAN

The following description of the ALARIS Medical Systems Retirement Investment Plan (“Plan”) provides only general information. Participants should refer to the Plan agreement for a more complete description of the Plan’s provisions.

General
The Plan is a defined contribution plan established to provide eligible employees with additional security for their retirement. The Plan covers substantially all eligible employees of ALARIS Medical Systems, Inc. (the “Company”) and is subject to the provisions of the Employee Retirement Income Security Act of 1974 (“ERISA”). Generally, employees are eligible to participate after completing one full payroll cycle. Employees may not be eligible to participate if they are a collectively bargained employee, a leased employee or an employee scheduled to work less than 20 hours per week (unless actual hours worked total more than 1,000 hours per year). An Administrative Committee consisting of four persons, appointed by the Company, has the authority to interpret the Plan and to resolve all questions arising in connection with the interpretation, application and administration of the Plan. Vanguard Fiduciary Trust Company (“VFTC”) serves as the Plan’s trustee.

Effective August 25, 2003, the ALARIS Medical Systems Stock Fund was reopened for contributions into the fund.

Contributions
Participants may make tax deferred contributions to the Plan of up to 20% of their eligible compensation, subject to the maximum permitted under the Plan and the Internal Revenue Code. Participants may also contribute amounts representing distributions from other defined benefit or defined contribution plans.

Effective January 2002, participants who are age 50 and older may make “catch-up” contributions to the Plan in accordance with the tax law that was passed in 2001.

The Company makes matching contributions equal to 50% of the first 8% of eligible compensation contributed. The Company also may make discretionary profit sharing contributions. There were no discretionary profit sharing contributions in 2003 or 2002.

Participant Accounts
Each participant’s account is credited with the participant’s contributions and an allocation of the Company’s contributions and Plan earnings and charged with an allocation of administrative expenses, if any. Plan earnings, which are not taxable to the participant under federal and state tax laws until withdrawn, are allocated on the basis of the participants’ account balances in the various investment alternatives.

Vesting
All participant contributions and related earnings credited to the participants’ accounts are fully vested and non-forfeitable. Company contributions and related earnings become 100% vested after one year of service with the Company.

Participant Loans
Plan participants may borrow up to 50% of their vested account balance, subject to a minimum of $1,000 and a maximum of $50,000. The loans are collateralized by the participants’ account balances. The loans bear interest at a rate of the prime rate plus 1%, determined on a quarterly basis and established when the loan is made. Interest rates range from 5.00% to 10.50% at December 31, 2003. Participants may have only one loan outstanding at a time, and may not have more than one loan in any 12-month period. If the participant is married, spousal consent is required to take a loan.

Notes to Financial Statements (Continued)


NOTE 1 - DESCRIPTION OF PLAN (Continued)

Payment of Benefits
Upon retirement, disability, death or termination of employment, a participant is entitled to 100% of his/her vested account balance, reduced by any participant loan outstanding. Participant accounts with balances up to $5,000 are settled with lump-sum distributions. Participants with a balance greater than $5,000 may elect a distribution, rollover, or to leave their balances in the Plan. Amounts left on deposit with the Plan and the earnings thereon are not forfeitable.

Participants also have an option to take hardship withdrawals, age 59½ withdrawals or other in-service withdrawals, subject to Plan provisions.

Forfeited Accounts
Forfeited balances of terminated participants’ non-vested accounts are used to reduce future Company contributions or pay administrative expenses. There were no forfeitures used in 2003 and forfeitures of $25,987 were used in 2002. At December 31, 2003 and December 31, 2002, forfeited non-vested accounts totaled $2,856 and $7, respectively.

Plan Termination
The Company may terminate the Plan for any reason at any time subject to the provisions of ERISA. In the event of termination, all participants will become 100% vested.

NOTE 2 - SUMMARY OF ACCOUNTING POLICIES

The following accounting policies, which conform with U.S. generally accepted accounting principles, have been used consistently in the preparation of the Plan’s financial statements.

Basis of Accounting
The financial statements of the Plan are prepared under the accrual method of accounting.

Use of Estimates
The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires Plan management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of additions and deductions during the reporting period. Actual results could differ from those estimates.

Investment Valuation and Income Recognition
The Plan’s investments are stated at fair value. Shares of registered investment companies are valued at quoted market prices which represent the net asset value of shares held by the Plan at year-end. Units of the Retirement Savings Trust are valued at net asset value at year-end. The Company stock fund is valued at its year-end unit closing price (comprised of year-end market price plus uninvested cash position). Participant loans are valued at cost which approximates fair value.

Purchases and sales of investments are recorded on a trade-date basis. Interest income is accrued when earned. Dividend income is recorded on the ex-dividend date. Capital gain distributions are included in dividend income.

Payment of Benefits
Benefits are recorded when paid.
