Earlier recording of a medically-ready-for-discharge date was associated with fewer unnecessary bed days in a US hospital system

A large US hospital system asked clinicians to estimate and record a Medically-Ready-for-Discharge Date (MRDD) in the electronic health record for hospitalised patients, and tracked a new delay measure, “unnecessary bed days” (UBD): the actual discharge date minus the MRDD. An analysis of the implementation covered discharges for 112,930 patient visits at four hospitals of the University of Rochester Medical Center between January 2021 and July 2022, with a detailed analysis of 33,771 Medicine and Paediatric patients Audit/Data (Dwyer-Matzky et al., PMID 42464290).

The longer the delay in entering the MRDD after admission, the greater the UBD. A longer interval between the first and last MRDD entry was associated with fewer UBD. Discharge disposition, level of care, insurance and day of the week were also significant predictors. The authors used multivariable regression and tree-based machine-learning methods to adjust for medical, demographic and operational characteristics.

These are observational associations from one health system, not proof that recording an MRDD earlier causes shorter delay, and the MRDD is itself a clinician’s estimate. The analysis is hospital-only: it measures time in a bed after medical readiness but not what was available in the community to receive the patient, so it cannot say whether a delay was avoidable by the hospital or set by onward capacity.

Its value for benchmarking is as a worked example of measuring non-value-adding bed time as a quantity, with the explicit unit of days between readiness and departure. The authors frame the gain as improved throughput in capacity-constrained hospitals; the study does not report the patient’s own experience of the extra days.
