RT Journal Article SR Electronic T1 Effects of bar code-assisted medication administration (BCMA) on frequency, type and severity of medication administration errors: a review of the literature JF European Journal of Hospital Pharmacy: Science and Practice JO Eur J Hosp Pharm FD British Medical Journal Publishing Group SP 489 OP 494 DO 10.1136/ejhpharm-2012-000058 VO 19 IS 5 A1 Jeroen Jules Margriet Hassink A1 Mark Marinus Peter Maria Jansen A1 Pieter Johan Helmons YR 2012 UL http://ejhp.bmj.com/content/19/5/489.abstract AB Bar code-assisted medication administration (BCMA) is increasingly being adopted as an additional tool in the prevention of medication administration errors. This literature review summarises the evidence behind the effects of BCMA technology on medication safety. Although most studies show an error-reducing effect of BCMA technology, compliance with the new technology after its implementation and the long-term effects on error reduction are often not assessed. Most importantly, the effect of medication error reduction on patient outcomes is limited.
