A radiology department generating hundreds of studies a day still routes most of them through a PACS that has no structured link to the EHR. A lab processing thousands of panels a week still reconciles results manually because the LIS speaks HL7v2 and the EHR expects FHIR. Neither gap shows up as a single failure. It shows up as turnaround time creeping up, as a clinician re-requesting a result because the first one never landed in the chart, as a false positive that gets caught two days too late because no one flagged the trend across three prior results.
These aren’t capacity problems. They’re integration problems wearing a capacity costume. A diagnostic solution that actually closes this gap has to treat PACS, LIS, and EHR as one connected read, not three systems exporting reports at each other.
