Improving Infusion Margin Without Adding Capacity
High-volume ambulatory infusion service with a mixed payer population
These are real cases I led in healthcare leadership roles: recovering aged receivables, improving infusion margin, and reducing technology overhead. Organization names and identifying details are withheld to protect confidentiality.

Situation
Infusion was among the largest revenue lines in the service and among the least profitable. The instinct in the room was to add capacity and hire nurses, on the theory that more volume would fix the margin. The current-state measures said the opposite: every incremental unit of capacity would have amplified the losses already embedded in the workflow.
Chair utilization looked acceptable in aggregate but collapsed under inspection. Appointments were scheduled in uniform blocks regardless of infusion duration, which meant a 90-minute therapy and a five-hour therapy occupied the same slot. Mornings were congested, mid-afternoons were dead, and nursing overtime accrued in the evenings finishing long infusions that had started too late.
Prior authorization was handled reactively. Authorizations were often chased on the day of service, producing same-day cancellations, wasted prepared drug, and rescheduled patients who displaced other bookings.
Drug acquisition was not managed as a margin lever at all. Purchasing followed habit rather than contract terms, vial sizing was not matched to dosing patterns, and waste was accepted as a cost of doing business.
What I Found
These findings shaped what I tackled first.
Uniform scheduling blocks against non-uniform therapies
Slot length ignored infusion duration, which guaranteed both idle chairs and end-of-day overtime in the same week.
Authorization work happened after scheduling, not before
Same-day authorization failures drove cancellations, drug waste, and a rebooking cycle that consumed capacity twice.
Drug spend was treated as pass-through, not managed
Vial sizing, dose rounding practice, and purchasing against contract terms were never reviewed together, so waste and acquisition cost both ran high.
Nursing ratios were set by headcount, not by acuity timeline
Staffing matched the amount of capacity rather than the shape of the day, producing simultaneous idle time and overtime.
What I Changed
Rebuilt the schedule around therapy duration
I grouped therapies into duration tiers and redesigned the template so long infusions started early and short ones filled the afternoon. The change required no capital and no new staff.
Moved prior authorization upstream with a hard rule
I set the rule that no patient went on the schedule without an authorization on file or a documented exception approved by a named person. Same-day authorization scrambles went from routine to rare.
Managed drug acquisition as an operational discipline
We matched vial sizing to actual dosing patterns, bought against contract terms, and tracked and posted waste weekly instead of absorbing it silently.
Matched nursing coverage to the redesigned day
I built coverage around the acuity timeline instead of headcount, which removed most evening overtime while improving the mid-day throughput.
Put a weekly scorecard on the wall
I posted chair utilization, waste rate, same-day cancellations, and overtime hours where the team could see them. The metrics stopped being a monthly surprise and became a daily habit.
What Changed for the Practice
Contribution margin improved by double-digit percentage points without adding physical capacity. Existing chairs were used more effectively, drug waste fell to a low single-digit rate, and nursing coverage aligned more closely with the actual shape of the infusion day.
The improvement came primarily from workflow redesign rather than added volume: scheduling by therapy duration, moving authorization upstream, managing acquisition and waste deliberately, and aligning staffing with demand.
The changes held after I stepped back because the team had a scheduling template, an authorization rule, a purchasing standard, and a visible scorecard.
Why It Worked
When a service line has strong revenue and weak margin, adding capacity multiplies the problem. Fix the workflow first, then decide whether you need more capacity. Most practices discover they do not.
Important Context
Results in your practice will depend on its operations, payer mix, market, leadership, staffing, and execution.
