Some veterans who present to smaller facilities, such as rural hospitals, are transferred to larger facilities for diagnostic or therapeutic procedures. But that access also can mean hardship for rural veterans by taking them far from family and adding costs. Moreover, complex care coordination can cause “triage mismatch” when the patients are at their most vulnerable: “over-triage”—transferring patients unlikely to benefit and “under-triage”—failing to transfer those likely to benefit.
Researchers from VA Iowa City Healthcare System and University of Iowa conducted a study to find out what proportion of VHA transfers were potentially avoidable. Their study included all veterans treated in any of 120 VHA emergency departments (EDs) and transferred to a VHA acute care hospital between January 2012 and December 2014.
Potentially avoidable transfers (PATs) were defined as transfers in which the patient was either discharged from the referral ED or admitted to the referral hospital for < 24 hours, without having an invasive procedure. The researchers chose that definition to identify patients whose transfer might have been avoided if real-time specialty telemedicine were available at the index hospital. (They caution that the definition was not intended to suggest that all PATs were inappropriate.)
Over 3 years, 18,852 patients were transferred. Of the total patients transferred, 36% were transferred from 1 VHA ED to another VHA facility. Of the VHA transfers, 8,639 (46%) were transferred to another VHA ED; the rest were transferred to another VHA facility inpatient unit. The median transfer distance was 81.5 miles. Rural residents were transferred 3 times as often as urban residents.
The good news is that PATs are rare. Only 0.8% of VHA ED visits resulted in transfer, and of those, only one-fourth were deemed potentially avoidable. And while rural veterans were more likely to be transferred, PATs were less prevalent among those transfers (20.8% vs 23.9% for urban veterans).
More than half of VHA transfers were for patients diagnosed with mental health, cardiac, and digestive conditions. The top ICD-9 diagnosis related to VHA ED transfer was suicidal ideation. The diagnostic procedures associated with most PATs were mental health (11% potentially avoidable) and cardiac (21% potentially avoidable).
Their research turned up some unexpected data: For example, smaller EDs did not have a higher prevalence of PATs, suggesting that ED size was not associated with transfer appropriateness. And the proportion of PATs was higher in hospitals with > 50% board-certified emergency physicians.
The researchers say their findings highlight important differences between the VHA health care and civilian health care systems, emphasizing that the resources available within the VHA health system “might be unique” and underlining the need for VHA-specific solutions to health care delivery challenges.
The overall purpose of this study, the researchers say, was to identify areas where novel delivery of specialty care might reduce the need for some VHA transfers. Their analysis provides data for developing targeted intervention, such as ED-based telemedicine or “targeted remote care.”
Patients with mental health conditions—who made up more than one-third of all VHA-to-VHA interfacility transfers, higher than that reported in civilian hospitals—represent a “rich target population” for telehealth, the researchers suggest. They also note that because mental health providers are in critical shortage in most of the US, real-time telemedicine providing psychiatric resources could be an important and timely service.
