Rationale, Aims And ObjectivesTransitions of care between healthcare facilities are associated with increased risk of adverse events and hospital readmissions. Previous studies employing pharmacists in transitions of care showed reduced 30-day readmissions, however, many were without an active comparator. There is no standardized approach to pharmacist involvement in transitions of care services, making it difficult to ascertain where pharmacist expertise is most meaningful. This paper aims to compare the 30-day hospital readmissions between an interprofessional hospital discharge visit (iHDV) with physician and pharmacist involvement to a non-interprofessional HDV (PHDV) without pharmacist involvement.MethodThis was a retrospective quality improvement initiative examining patients of two outpatient clinical practices within a large, academic medical centre. The primary analysis compared 30-day hospital readmission rates for patients with a scheduled PHDV or iHDV within 30-days of index hospital discharge date, regardless of attendance at the HDV. The secondary outcome compared 30-day hospital readmission rates for patients who completed a PHDV or iHDV. Primary and secondary outcomes were evaluated using bivariate analysis and multivariate analysis by stepwise logistic regression, for both intention-to-treat (ITT) and per protocol (PP).ResultsThis study found significantly lower 30-day hospital readmissions for patients scheduled for a PHDV compared to an iHDV (16.7% vs 21.5%, P = .0230) in an unadjusted analysis, but no significant difference in adjusted analyses (P = .4856). Per-protocol analysis found no significant difference in 30-day hospital readmission rates between groups in unadjusted and adjusted analyses. Visit completion rates were significantly different between groups, with approximately twice as many PHDV group patients completing visits as compared to the iHDV group (74.1% vs 61.5%, P < .0001).ConclusionThis study demonstrates an interprofessional clinic visit employing a clinical pharmacist in the post-hospital discharge visit did not significantly reduce 30-day hospital readmission rates compared to a post-hospital discharge visit without pharmacist involvement.© 2020 John Wiley & Sons Ltd.
