Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions (see General Instruction A.2. below):

As previously announced, IMS Health Incorporated (the “Company”) has entered into an Agreement and Plan of Merger, dated as of November 5, 2009, by and among the Company, Healthcare Technology Holdings, Inc., a Delaware corporation, and Healthcare Technology Acquisition, Inc. (“Merger Sub”), a Delaware corporation and a wholly owned subsidiary of Healthcare Technology Holdings, Inc., providing for the merger (the “Merger”) of Merger Sub with and into the Company.

As previously disclosed in more detail in the Definitive Proxy Statement on Schedule 14A filed with the Securities and Exchange Commission (the “SEC”) by the Company on December 29, 2009 (the “Definitive Proxy Statement”), in connection with the Merger, three putative stockholder class action lawsuits were filed in the Delaware Court of Chancery and two in the Superior Court of Connecticut, Judicial District of Stamford. These lawsuits generally alleged breaches of fiduciary duty by the Company’s directors in connection with the Merger. On December 2, 2009, the three putative shareholder class action lawsuits filed in Delaware were consolidated into a single action, captioned In re IMS Health Inc. Shareholder Litigation, C.A. No. 5057-CC (the “Delaware Action”).

On January 14, 2010, the plaintiffs in the Delaware Action filed a Notice and Order of Voluntary Dismissal of all their claims, without prejudice, in which they represented that no compensation in any form has passed directly or indirectly from defendants to plaintiffs or plaintiffs’ attorneys and that no promise to give any such compensation has been made. The Court of Chancery granted the dismissal on January 15, 2010.

As of the date hereof, the two putative shareholder class action lawsuits filed in the Superior Court of Connecticut, Judicial District of Stamford remain pending.

ADDITIONAL INFORMATION AND WHERE TO FIND IT

In connection with the proposed Merger, the Company filed the Definitive Proxy Statement and a form of proxy with the SEC on December 29, 2009 and the Definitive Proxy Statement and a form of proxy were mailed to the stockholders of record of the Company as of December 28, 2009. BEFORE MAKING ANY VOTING DECISION, STOCKHOLDERS OF THE COMPANY ARE URGED TO READ THE DEFINITIVE PROXY STATEMENT CAREFULLY BECAUSE THE DEFINITIVE PROXY STATEMENT CONTAINS IMPORTANT INFORMATION ABOUT THE PROPOSED MERGER. The stockholders of the Company will be able to obtain, without charge, a copy of the Definitive Proxy Statement and other relevant documents filed with the SEC from the SEC’s website at http://www.sec.gov. The stockholders of the Company will also be able to obtain, without charge, a copy of the Definitive Proxy Statement and other relevant documents by written or telephonic request directed to IMS Health Incorporated, Attn: Investor Relations, 901 Main Avenue, Norwalk, Connecticut 06851, telephone: (203) 845-5200, on the Investors page of the Company corporate website at www.imshealth.com, or from our proxy solicitor, Innisfree M&A Incorporated, toll-free at (888) 750-5835 (banks and brokers call collect at (212) 750-5833).
