Why Purchase Price Doesn’t Tell the Whole Story
In blood collection, “cheapest” and “best value” are rarely the same thing. A device’s sticker price ignores costs that matter more to patients and operations—injury risk, redraws, and lost minutes at the bedside. When you model the Total Cost of Safety (TCS) you can justify safety-engineered devices with a business case that stands up to Value Analysis, Supply Chain, and Finance.
This post walks through a simple, defensible model that quantifies (1) injury-cost avoidance, (2) redraw prevention, and (3) labor minutes saved—so your team can choose devices on outcomes, not just on unit price.
The TCS Framework (At a Glance)
Think of TCS as a roll-up of what you pay and what you save:
TCS per year = Device Cost ± Net Change in:
- Sharps Injury Costs (medical testing, treatment, reporting/admin time, lost time)
- Redraw Costs (extra tubes/devices, lab processing, delays, patient experience impact)
- Labor Minutes (fewer activation errors, fewer troubleshooting steps, faster setup/cleanup)
Goal: show leadership how a “higher-priced” safety device can lower total cost per successful draw while improving staff safety and patient experience.
1) Injury-Cost Avoidance (ESIP Matters)
Safety-engineered sharps (ESIP—Engineered Sharps Injury Protection) are designed to reduce needlestick injuries and near-misses. Each prevented injury avoids:
- Direct medical costs: source patient testing, exposed staff testing, prophylaxis when indicated
- Admin & compliance: incident reporting, follow-up, occupational health visits
- Lost time: shift coverage, overtime, and productivity loss
Model it:
- Baseline injury rate with current device (per 100,000 draws)
- Expected injury rate with the safety device (per 100,000 draws)
- Cost per injury (all-in; conservative average)
- Injury savings = (Baseline − Expected) × Cost per injury
Tip: Use conservative numbers and cite your incident logs plus published ranges. Round to the nearest whole injury across annual draw volume.
2) Redraw Prevention (Sample Integrity Is Money)
Redraws cascade into wasted supplies, delayed results, and lower patient trust. Common drivers include hemolysis, underfills, and mislabeling—all of which improve with consistent activation and standardized technique.
Model it:
- Baseline redraw rate (per 100 draws)
- Redraw rate with the proposed device standardized (per 100 draws)
- Cost per redraw (extra device/tubes, staff time, lab processing, potential re-rooming)
- Redraw savings = (Baseline − Expected) × Cost per redraw × Annual draws
Pro move: If units differ (ED vs. Med-Surg), model unit-specific redraw rates and roll up to catch high-impact pockets.
3) Labor Minutes Saved (Activation, Setup, Cleanup)
Not all minutes are equal: fewer steps, fewer activation errors, and less device confusion translate into reclaimed time on busy units. You don’t have to find hours—saving 15–30 seconds per draw becomes meaningful at scale.
Model it:
- Average seconds saved per draw (activation simplicity, fewer do-overs, cleaner disposal)
- Draws per year × seconds saved = total minutes saved
- Multiply by a loaded cost per minute (wage + benefits or blended rate)
- Labor savings = total minutes × cost per minute
Keep it conservative: run a short time-and-motion sample (e.g., 20 draws, two devices) and use the lower bound for decisions.
Pulling It Together: A Simple Worked Example
Assumptions (illustrative):
- Annual draws: 250,000
- Current device unit price: $0.90 → proposed safety device: $1.10
- Injury rates (per 100,000 draws): baseline 7, expected 3; Cost per injury: $3,200
- Redraw rates (per 100 draws): baseline 3.0%, expected 2.2%; Cost per redraw: $28
- Labor time saved: 18 seconds/draw; Loaded cost: $0.60/minute
A) Device spend delta
250,000 × ($1.10 − $0.90) = +$50,000
B) Injury avoidance
((7 − 3) / 100,000) × 250,000 = 10 avoided injuries → −$32,000
C) Redraw prevention
(0.030 − 0.022) × 250,000 = 2,000 redraws avoided → −$56,000
D) Labor minutes saved
250,000 × 18 sec = 4,500,000 sec = 75,000 minutes → −$45,000
Net TCS Impact (year 1)
+$50,000 − $32,000 − $56,000 − $45,000 = −$83,000
Despite the higher unit price, the total program saves ~$83K/year while improving staff safety and patient experience.
How to Build Your Business Case (5 Steps)
- Establish baselines: injury rate, redraw rate, average minutes per draw (same timeframe).
- Pilot & measure: standardize the proposed device on two units (ED/ICU), run 30–60 days, capture near-misses, redraws, and a simple time-and-motion sample.
- Quantify savings: apply conservative, documented rates; prefer ranges (best/expected/worst).
- Include program costs: training time, onboarding materials, initial stock adjustments (pars/FEFO).
- Report TCS per successful draw: show leadership how total cost per completed, acceptable specimen trends down.
What Improves When You Standardize
- Safety activation consistency with a single mechanism (e.g., RELI® Push-Button Safety Blood Collection Set or RELI® Safety Slide™ Blood Collection/Infusion Sets) → fewer activation errors/near-misses.
- Technique reliability (gauge selection, anchoring, order of draw, gentle inversions)—see How to Select the Right Blood Collection Device for a quick refresher.
- Inventory discipline First Expired, First Out (FEFO) rotation, clear pars, fewer substitutions) → fewer expiries and less confusion on carts.
- Training clarity: one activation method → faster onboarding, lower cognitive load.
- Patient experience: fewer re-sticks, faster time-to-result, more trust.
Key Performance Indicators (KPIs) to Track (and Share Monthly)
- Sharps injury rate (per 100,000 draws)
- Redraw rate (per 100 draws) and hemolysis rate
- Cost per successful draw (device, waste, and labor rolled up)
- Minutes per draw (activation → label → disposal)
- Expired SKUs and stockouts per unit (inventory health)
- Near-miss reports related to device activation/technique
Talking Points for Value Analysis & Finance
- Total cost vs. unit cost: the model shows real dollars tied to injuries, redraws, and minutes.
- Risk reduction: fewer sharps injuries reduce direct costs and tail risk.
- Throughput impact: saving seconds per draw scales across high-volume units.
- Measurable within 90 days: an ED/ICU pilot surfaces trends quickly.
- Patient-centered: fewer re-sticks and smoother draws improve experience measures.
Implementation Checklist (90 Days)
Days 0–30
- Select a safety device and lock one activation mechanism.
- Define unit-level pars and mark FEFO rotation.
- Draft quick training cards (activation steps, order of draw, inversion counts).
- Establish baseline metrics and a pilot dashboard.
Days 31–60
- Pilot on two units; 15-minute in-service + bedside coaching.
- Track injuries/near-misses, redraws, and a time-and-motion sample.
- Hold two cadence huddles to remove friction (labeling, bin layout, restock triggers).
Days 61–90
- Present TCS results (best/expected/worst); request go/no-go for scale-up.
- Tune pars; finalize alternates; plan training for next units.
- Publish the first monthly KPI report to Nursing, Lab, and Supply Chain.

Frequently Asked Questions
How do we estimate cost per injury if our data is sparse?
Use a conservative blended figure that includes testing, prophylaxis (when indicated), admin time, and lost time. Round down to avoid overstating the case; sensitivity-test the model at 50–150% of that value.
What if our redraws are already “low”?
Even a 0.5–0.8% absolute reduction is significant at scale and often enough to neutralize a higher unit price when paired with labor savings.
Won’t training time erase the savings?
Training is a one-time cost. Standardizing a single activation mechanism actually reduces future training minutes and onboarding complexity.
Can we track minutes saved without a time study team?
Yes—use a simple stopwatch protocol across 20–30 draws with two devices and two operators. Document conditions and use the lower bound in the model.
