The risks of blood stream infections are especially high in patients who have a history of intravenous drug use (IVD). These patients are more likely to manipulate the central line, which may result in a central line-associated bloodstream infection (CLABSI). Claims associated with these infections may not be reimbursed by insurance companies, encumbering the hospital with the costs. Furthermore, such patients cannot be safely discharged to outpatient care or to a skilled nursing facility, which leaves the hospital unable to free up beds.


TEL BOXX is a tamper-evident device that also minimizes unauthorized access to the central line. This device has a specially designed contoured enclosure that covers the lumen interface points in the central line and shows unambiguous evidence of having been opened by either a nurse or a patient. The value of the device has been demonstrated in high-risk patients recovering from endocarditis. The nurses at these hospitals stated that the device would not only demonstrate real evidence of inappropriate access to the central line but would also provide deterrence of inappropriate access to the central line. The nurses also stated that the device is easy to use and does not impair their workflow.
According to National Health Safety Network (September 2017):

“A positive blood specimen meeting LCBI criteria, that is accompanied by documentation of observed or suspected patient injection into vascular access lines, within the BSI infection window period, will be considered an LCBI, BUT NOT a CLABSI for NHSN reporting purposes.”

According to a registered nurse at a hospital that uses TEL BOXX:

“If patient utilize this device and tampering is detected that is basically all the evidence needed to document suspected injecting.”

This device will enable hospitals to discharge patients with a history of IVD to outpatient care for further antibiotic treatment knowing that the IV line will not be used.


  • Provides needed evidence of tampering with the central vascular access device so that the required documentation can be entered into the patient’s medical record can state “Patient is suspected of injecting …” in case a CLABSI is detected in the future
  • Increased safety for patients with a history of IVD requiring vascular access
  • Cost savings by expediting patient transfer to SNFs, LTACHs, or ambulatory clincis for continued treatment
  • Durable and easy to use
  • Minimally impacts nurse work flow
