Integrative Review

Decent Essays

DISCUSSION This integrative review sought to identify and understand the impact of information technology in on medication errors. The review of 14 papers shows that the implementation of medication management systems, which include CPOE, BCMA and automated dispensing machines has successfully reduced medication errors and adverse medication events significantly, particularly the two most susceptible stages of prescription and administration of drugs (Armada et al., 2014). The findings suggested positive impact of CPOE systems in reducing or eliminating disadvantages of manual prescription. Implementation of CPOE systems has improved medication error rates attributed to prescribing (Armada et al., 2014; Helmons et al., 2009; Roberts et …show more content…

The "Hawthorne effect" is often associated with positive results as it creates awareness of being observed, and study participants consciously change their behavior to actively comply with the researcher’s wishes (Wickström & Bendix, 2000). However, some studies suggested a negligible effect of direct observation on the observed participants (Buckley, Erstad, Kopp, Theodorou, & Priestley, 2007; Kopp, Erstad, Allen, Theodorou, & Priestley, 2006). There was no significant difference on medication error rates between the first and last day of observation (DeYoung et al., 2009). The time spent by researches with nurses to acclimate to researchers' presence before the start of study has minimized the Hawthorne effect (Dwibedi et al., …show more content…

One study reported nurses' compliance rates of 90% (Paoletti et al., 2007), but the other study found that 20% of the drugs were administered without scanning the barcode to ensure right medication (Poon et al., 2010). Helmon et al (2009) reported an increased in compliance rate in checking patients' identities by scanning patients' wristbands in medical-surgical wards, but no difference in the ICUs. Possible reasons for non-compliance in ICUs could be due to high nurse-patient ratio, and that the nurses were often assigned to the same patients (Helmons et al., 2009). Non-compliance in barcode scanning and workarounds could possibly affect the medication error rates. Therefore, it is difficult to interpret the effect of BCMA on medication administration errors due to differences in study designs, study settings and outcome measurement. Further research is required to include more patient care units, and to examine the effect of nursing activities on the impact of BCMA and medication
