BackgroundThe factors that limit primary care providers (PCPs) from intervening for adults with evolving, acute, severe illness are less understood than the increasing frequency of management by acute care providers.MethodsRates of prehospital patient management by a PCP and of communication with acute care teams were measured in a multicenter, cross-sectional, descriptive study conducted in all four of the adult medical ICUs of the three hospitals in central Massachusetts that provide tertiary care. Rates were measured for 390 critical care encounters, using a validated instrument to abstract the medical record and conduct telephone interviews.ResultsPCPs implemented prehospital management for eight episodes of acute illness among 300 encounters. Infrequent prehospital management by PCPs was attributed to their lack of awareness of the patient's evolving acute illness. Only 21% of PCPs were aware of the acute illness before their patient was admitted to an ICU, and 33% were not aware that their patient was in an ICU. Rates of PCP involvement were not appreciably different among provider groups or by patient age, sex, insurance status, hospital, ICU, or ICU staffing model.ConclusionsWe identified lack of PCP awareness of patients' acute illness and high rates of PCP referral to acute care providers as the most frequent barriers to prehospital management of evolving acute illness. These findings suggest that implementing processes that encourage early patient-PCP communication and increase rates of prehospital management of infections and acute exacerbations of chronic diseases could reduce use of acute care services.
