Background/objectives: Hospitalized older adults are at risk of receiving potentially inappropriate medication (PIM) doses, driven in part by age-independent dose defaults used by electronic health records (EHRs), leading providers to prescribe for older adults as they do for younger adults. We studied whether an automated EHR-based medication support tool would reduce PIM dosing for hospitalized older adults., Design: Pre-post study design., Setting: Tertiary care, level 1 trauma, academic medical center in Oregon., Participants: Hospitalized adults 75 years and older in the inpatient, nonemergency setting prescribed medications with geriatric-specific dose considerations., Intervention: An EHR-based, automated set of evidence-based, age-specific dose and frequency defaults called the Geriatric Prescribing Context (GPC)., Measurements: The process measure is percentage of orders consistent with geriatric dose recommendations, and outcome measures are average dose (AD) in milligrams and total daily dose (TDD) in milligrams in the 12 months before and after implementation., Results: Use of recommended geriatric doses with the context improved for all 10 of the most commonly ordered medications. In the year after implementation, there was a trend toward decreasing TDD and AD across all drug classes., Conclusion: The GPC is a simple, elegant, and effective means to align prescribing practices with safety standards for older adults, improving prescribing safety for all. It works within the current prescriber workflow without triggering alert fatigue and requires minimal resources for development and maintenance., (© 2020 The American Geriatrics Society.)

Background: The medication‐related death of a hospitalized older adult elucidated the inappropriateness of medication default doses in our electronic health record (EHR) for older adults. In response, we created and implemented the Geriatric Prescribing Context (GPC), an EHR‐based set of age‐specific dose and frequency defaults for patients 75 years and older, in July 2017. Inpatient medication orders aligned with GPC defaults and showed significant dose decreases at one year for nine of ten most commonly used medications. This follow‐up investigation examined GPC alignment of dose and frequency over the 42‐month time period after its implementation. Methods: Order data for the ten most commonly used medications at OHSU Hospital were collected retrospectively from July 2016 through December 2020. We used Statistical Process Control charts to assess the proportion of medication orders aligning with the GPC's recommendations. Signals of special cause were evaluated to identify time periods when shifts in process averages likely occurred and suspected shifts were assessed using binomial proportion tests. We used RStudio (RStudio, Inc., version 1.2.5001) and Microsoft Excel (2016) to perform statistical analyses and control charts, respectively. Results: The preimplementation phase of all medications displayed no special causes. After significant initial improvement in 2017, control charts revealed three different patterns of performance. Eight medications maintained the initial improvement with one medication displaying a second significant improvement at a later date. Two medications showed a subsequent decline in performance not statistically different from baseline. Overall, eight of the ten medications were prescribed at more age‐friendly doses and frequencies compared to baseline after 42 months. Conclusions: The GPC is an effective method to support safer prescribing for hospitalized older patients, but long‐term impacts may be medication‐specific. Further investigation is needed to ensure appropriate prescribing across drug classes and understand the GPC's impact on patient outcomes like adverse drug events. [ABSTRACT FROM AUTHOR]

The impact of a novel Geriatric Prescribing Context (GPC) on hospital clinicians' prescribing workflows is still unknown. A cross-sectional survey was distributed to 346 inpatient pharmacists, physicians, and advance practice providers employed at three pilot site hospitals affected by the GPC to assess awareness and impact to usual workflow. The GPC, a set of medication default doses and frequencies for patients 75 years and older, was unnoticed by 74% of survey respondents (n = 119) with pharmacists more likely to be aware of the context than prescribers. The impact of the GPC on clinicians' workflow differed by setting, with academic respondents reporting no change or decreased time to write or verify orders, and community respondents reporting no change or increased time to write or verify orders. The GPC has smoothly integrated into usual prescribing workflows for both prescribers and pharmacists and both overall reported positive responses to the implementation. [ABSTRACT FROM AUTHOR]
