Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	The unaudited interim consolidated financial statements of the Company have been prepared in accordance with instructions for Form 10-Q and the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) have been condensed or omitted pursuant to such rules and regulations. The unaudited interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company's 2012 Annual Report on Form 10-K, filed with the SEC on April 1, 2013. Financial statements prepared in accordance with U.S. GAAP require management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses and other disclosures. The financial information included herein is unaudited; however, such information reflects all adjustments that are, in the opinion of the Company's management, necessary for a fair statement of results for the interim periods presented. The results of operations for the three and nine month periods ended September 30, 2013 and 2012 are not necessarily indicative of the results to be expected for any other interim period or the full year. See “Management's Discussion and Analysis of Financial Condition and Results of Operations” for additional information.
Discontinued Operations	On September 30, 2013, the Company completed the sale of certain assets comprising its Portamedic service line. The Portamedic service line is accounted for as a discontinued operation in this Report. Accordingly, the assets and liabilities of Portamedic that were sold have been reclassified and are reported as assets and liabilities held for sale on the December 31, 2012 consolidated balance sheet. The operating results of Portamedic are segregated and reported as discontinued operations in the accompanying consolidated statements of operations for all periods presented. Certain costs presented within continuing operations in the financial statements, notably selling, general and administrative costs, may not be indicative of costs going forward because those costs have historically been shared among service lines and the continuing operations have been and are being restructured. There is no guarantee that costs allocated to Portamedic and included in discontinued operations will be eliminated in future periods. For further discussion on Discontinued Operations, please see Note 6.

Disclosure of accounting policy for any discontinued operations. The results of operations of a component of an entity that either has been disposed of or is classified as held for sale is reported in discontinued operations if both: (a) the operations and cash flows of the component have been (or will be) eliminated from the ongoing operations of the entity as a result of the disposal transaction and (b) the entity will not have any significant continuing involvement in the operations of the component after the disposal transaction. If the entity elects to allocate interest expense to a discontinued operation, it may disclose its accounting policy for this election and describe its method of allocation.
