BackgroundInaccurate medication documentation in prescriptions and discharge summaries produce poorer patient outcomes, are costly to healthcare systems and result in more readmissions to hospital. Errors in medication documentation are common in Australian hospitals.AimTo determine whether pharmacist‐led partnered prescribing (PPP) on discharge reduced errors and improved accuracy in documentation of medications in the discharge prescription and the discharge summary of people with kidney disease compared with medical prescribing (MP).MethodsThis interventional two‐phase study compared current workflow (MP) with the subsequent implementation of the interventional workflow (PPP) in the renal unit of a tertiary referral hospital. Patients were included if they were discharged within pharmacy working hours and had a discharge prescription and discharge summary. The primary outcome was the percentage of discharge prescriptions with at least one error. The secondary outcome was the percentage of discharge summaries with at least one error.ResultsData were collected from 185 discharged patients (95 in MP phase then 90 in PPP phase). Discharge prescriptions with at least one error reduced from 75.8% in the MP phase to 6.7% in PPP phase (P < 0.001). Discharge summaries with at least one error reduced from 53% in MP phase to 24% in the PPP phase (P < 0.001).ConclusionPPP improves the accuracy of the documentation of medications in both the discharge prescription and the discharge summary of patients with kidney disease.
