Daily pharmacist coverage may be a critical part of intensive care
Intensive care units rely on tightly coordinated teams to manage patients with complex, rapidly changing conditions. New research led by the University of Georgia suggests that one member of that team—the critical care pharmacist—may have a measurable association with patient survival when present every day.
The study, published in the journal CHEST, found that ICU patients who went without pharmacist care for even one day during their stay were 20% more likely to die. It also found an association between larger pharmacist workloads and higher mortality: patients were 10% more likely to die when a pharmacist was responsible for more than 15 patients.
The findings do not establish that pharmacist staffing alone causes the difference in outcomes. But they add unusually specific evidence to a broader argument that medication expertise should be continuously available in high-acuity settings, including on weekends and holidays.
What the researchers examined
Researchers analyzed information from 213 pharmacists working across 64 hospitals. The pharmacists reported their workloads and the patients they cared for on each day over a 100-day period. The resulting dataset included more than 28,000 patients, alongside information on illness severity, health outcomes, and other factors.
Lead author Susan Smith, an associate professor in the University of Georgia’s College of Pharmacy who also practices critical care pharmacy, said medication management is central to patient safety in the ICU. Critically ill patients experience an average of 1.7 medical errors per day, according to the article, and medications account for nearly 80% of serious errors.
Critical care pharmacists review medications for interactions, help optimize doses, and assess whether an alternative treatment may better fit a patient’s condition. In an ICU, those decisions can be especially consequential because patients often receive multiple drugs, may have impaired kidney or liver function, and can change clinically over a short period.
Workload emerged as another concern
The analysis also points to workload as a potential operational constraint. For every additional patient assigned to a pharmacist, the odds of a patient dying increased by 1%, according to the study. The reported 10% increase in mortality risk when pharmacists had more than 15 patients suggests that simply assigning a pharmacist to an ICU may not be enough if coverage is spread too thin.
That finding could matter as hospitals face budget pressure and staffing decisions. Around-the-clock specialty pharmacist coverage is not always treated as a priority, but the researchers argue that the costs of adequate staffing may be offset by improved safety and fewer adverse drug events.
The study’s authors frame pharmacist participation as a safeguard in a care environment where medication decisions are frequent and highly individualized. Their results build on previous evidence that pharmacist involvement in ICUs improves outcomes, while adding a focus on consistency of coverage and the number of patients each pharmacist is asked to support.
Implications for hospital staffing
For hospital leaders, the research raises practical questions about how ICU services are staffed across all days of the week. A model that provides pharmacist input only during selected shifts may leave gaps during which medication-related risks are harder to detect or address quickly.
The authors’ central conclusion is that ICU pharmacist services should be available every day of the year. The study also indicates that staffing benchmarks may need to account for caseload, not merely whether a pharmacist is formally assigned to an ICU.
Further research will be needed to clarify how staffing models, hospital resources, and patient populations affect these associations. Still, the new analysis provides evidence that pharmacy coverage belongs in the discussion of critical-care capacity alongside physicians, nurses, respiratory therapists, and other specialists.
- The study covered more than 28,000 patients across 64 hospitals.
- A one-day gap in pharmacist care was associated with 20% higher mortality.
- Higher pharmacist caseloads were also associated with worse patient outcomes.
