Indeed, the insertion of central lines is currently performed by a range of health workers, including (junior) doctors from specialties ranging from radiology to anesthesiology as well as nurse specialists. One report,1 which is now 10 years old, estimated the insertion of central lines in the National Health Service of the United Kingdom at 200,000, or 3 lines per 1,000 inhabitants in the United Kingdom. Extrapolating this figure to the United States, where central lines are more frequently used, would result in an estimated 750,000 to 1 million central lines inserted per annum. This number highlights the importance of addressing the insertion of central lines, as any improvement or change in practice will obviously have a significant impact on patient care and on health-care economics. Thus, any improvement of the procedure or any cost saving (even if this seems relatively small, such as with a routine chest radiograph) will result in major savings at a macroeconomic level as well as have an effect on manpower planning (after all, many of these routine radiographs are obtained at bedside and/or out-of-hours).
