South Florida Hospital System — Cart Fleet Caster Standardization

Background

Miami-Dade has 50+ hospitals and ASCs running thousands of mobile carts — med carts, surgical instrument carts, dietary, pharmacy automation, laundry, IV poles, and supply transport. This hospital system, with 3 campuses across South Florida, was averaging 400+ med carts at any given time.

The Specification Problem

Maintenance was getting caster failures every 6-8 months. The hospital’s procurement team was placing emergency orders 5-6 times per quarter, ordering from whichever vendor responded first. Result: a “caster graveyard” of mixed-spec wheels — different sizes, different mount types, different tread materials — with maintenance staff spending hours hunting for matching replacements.

The root cause was not the casters themselves. It was:

1. Corrosion from daily disinfectant exposure (chlorine, peracetic acid)
2. Inconsistent specs across carts from different OEMs
3. No standardized replacement program — every fix was a one-off

What Douglas Spec’d

After a 2-hour walk-through with facilities and maintenance, Douglas recommended:

• 316 stainless steel housings — survive aggressive sanitizers
• Sealed bearing pack — no chemical ingress
• TPR (thermoplastic rubber) tread — quiet, non-marking, chemical-resistant
• Total-lock brakes — patient safety in transport
• Standardized SKUs — 3 SKUs to cover the entire fleet (light cart, med cart, heavy supply cart)

A standing-order program was set up with consistent inventory and net-30 terms.

The Result (12-Month Audit)

Metric	Before	After 12 months
Caster failures / month	32 average	9 average
Procurement time / quarter	~6 hours	under 1 hour
Number of SKUs in stock	14	3
Total cost (parts + labor) Year 1	Baseline	-$14,000

Cart maintenance shifted from a weekly emergency to a scheduled monthly task. Maintenance staff now grab from a 3-bin inventory and complete swaps in under 5 minutes per cart.

Why It Worked

The win was not the casters — it was the audit. Douglas asked the right questions about cleaning chemicals, floor types, transport distances, and noise constraints. The specification matched the application the first time.
