Data were analysed descriptively for variation with time and between wards. All staff gave verbal consent. Ethics approval was not required as this was a service evaluation. All five outcomes varied weekly as illustrated by the relatively large standard deviations to the mean (Table 1). Table 1 Summary of findings for the five main outcome measures on the two study wards Outcome measures Medical ward Surgical ward n Mean SD Range n Mean SD Range SD, standard deviation. Pharmacists spent 62% of their time reviewing medications and making interventions; 19% ordering medications and transcribing drug charts; and 18% on other ABT-888 mouse tasks. Nurses

spent 82% of their time on medication related tasks; 7% searching for medications and drug charts; and 11% on other tasks. Pharmacists worked alone 81% of the time, 10% with other healthcare professionals (HCPs) and 9% with patients. Nurses Smad inhibitor worked alone and with patients for the majority of the time (50% and 44% respectively), 5% with other HCPs and 1% with others. We identified variation in outcome measures over time and between

two wards; our findings support the use of an interrupted time series method for evaluating an EPMA system and our data collection forms can be used to evaluate the roll-out of the EPMA system in the study hospital. Relatively short study period and local variation in practice limits the generalisability

SPTBN5 of the findings beyond the study hospital. Differences in prescribing error rate, interventions and quality of allergy documentation between wards may be due to differences in ward pharmacy services provided; future data should be collected on both types of pharmacy service days for the same ward. 1. Department of Health.

Pre and post intervention NPSA risk scores were assigned to recipients of a domiciliary medicines support service by a panel of four different healthcare professionals to determine whether receipt of the service reduced the patients’ medicines related risk of harm. Significant reductions in the average NPSA risk scores were observed post intervention, suggesting intervention benefit.
