One patient, one MRN, one built-in ledger, one live command centre — from the registration counter to the operating theatre.
Why EloHIMSChemotherapy is unforgiving of ambiguity: the wrong drug, dose or cycle carries real harm. EloHIMS runs the day-care unit as a sequence of checks the system enforces — the regimen, the pre-cycle labs, the signed consent, a second person checking the prepared drugs, toxicity grading after the cycle and the date of the next one.
At its core is a chemotherapy plan held against each patient: the regimen from the Regimen Library, its cycle length, and the number of cycles planned. Each cycle then moves through fixed states — scheduled, pre-meds, infusing, completed — and the server decides whether it may move on: the labs must clear the regimen's thresholds, a signed consent must be on file, and the prepared drugs must be checked by a second person. After the cycle, toxicity is graded and the next cycle date is set from the regimen.
When a cycle is booked or started, EloHIMS works out the fitness status itself from the labs entered: ANC, platelets, creatinine, bilirubin, ALT, and weight loss against the weight on the plan. The thresholds are set per regimen in the Regimen Library. A "fit" status sent by the screen is ignored — the server recalculates it.
If the labs fall outside the thresholds, or no labs have been entered, the cycle is held. Going ahead needs a user who holds the chemo override permission and a written override reason, both stored on the cycle. A held cycle cannot be saved as completed, and held cycles show as on hold on the chemo work queue.
An independent double-check of the prepared drugs is only independent if the system can tell the two people apart. In EloHIMS the preparer records the preparation under their own login, and a different user records the check under theirs. Until both are on the cycle, the move to infusing is refused.
The gate result, any override and its reason, the consent and the two users who prepared and checked the drugs all stay on the cycle, so the record shows who cleared each stage.
Once a cycle is completed, the team grades toxicity on CTCAE v5 across 16 terms used in day-care — alopecia graded 0–2, nausea and fatigue 0–3, the rest 0–5. The worst grade is kept on the cycle, and any grade 3 or above is flagged on the patient's plan, where the oncologist sees it before booking the next cycle.
Completion also sets the next cycle date: day 1 of this cycle plus the regimen's cycle length. The plan shows the date, turns it amber when it is overdue, and pre-fills it on the next booking. After the last planned cycle, no next date is set.
A chemotherapy day-care unit where no cycle starts without cleared labs or an authorised override, a signed consent and a second person's drug check — and every cycle ends with graded toxicity and a dated next cycle.
A pre-cycle lab gate, signed consent, a two-person drug check, CTCAE v5 toxicity and the next cycle dated from the regimen — on one patient record.
