Is ward round participation by clinical pharmacists a valuable use of time and money? A time and motion study.

Abstract

While the benefits of multidisciplinary ward round (WR) participation by clinical pharmacists have been demonstrated, it can be time-consuming. No previous studies have compared the specific benefits of WR participation and other clinical activities. To assess the clinical impact of different clinical pharmacist activities and analyse patterns of practice based on WR involvement and timing and significance of clinical interventions. In a prospective, observational time and motion study, clinical pharmacists servicing 6 unmatched specialty areas in a major quaternary public hospital were observed and their activities documented. Pharmacists' self-recorded interventions underwent expert panel assessment for significance and potential cost savings. Workflows and interventions were analysed for the 4 pharmacists involved in WRs ('WR pharmacists') during their time 'on' and 'off' rounds and for 2 pharmacists not involved in WRs ('non-WR pharmacists') using chi-square analyses. During 170 h of observation, 267 clinical interventions (53.9% minor, 40.1% moderate, 6.0% major) were recorded. WR pharmacists spent 24.3% of their time on rounds, and 64.8% of interventions were made during this time (intervention rates: 4.5/hour on WR vs. 0.8/hour off WR vs. 1.3/hour for non-WR pharmacists). Differences in WR and non-WR pharmacists' workflows were observed, although there was no difference in time spent on clinical/patient-centred activities (p = 0.70). WR involvement was associated with significantly quicker interventions (p < 0.001). All major interventions were made by WR pharmacists; 80% were made on rounds. Major interventions were estimated to have decreased lengths of stay, intensive care requirements and procedure costs. Clinical pharmacists focussed on patient-centred activities, regardless of WR involvement. Notwithstanding differences in the WR and non-WR specialty areas, WR participation was associated with more significant and timely interventions and potential cost savings. Coupled with the subjective benefits of WR participation observed, these findings support the potential value of clinical pharmacist WR participation.
