Staffing Decisions That
Protect Patients and Control Costs

In an era of nursing shortages and labor cost pressure, staffing decisions made without real-time data carry patient safety and financial consequences. Vizier tracks acuity-adjusted ratios, overtime patterns, and patient flow metrics — so you know what you need before the shift starts.

Staffing Ratios & Acuity Adjustment

California Mandated Ratios vs. National Standards — Tracked in Real Time

California AB 394 mandates specific nurse-to-patient ratios: 1:2 in ICU, 1:3 in step-down, 1:4 in medical-surgical, 1:4 in pediatrics, 1:5 in telemetry, and 1:6 in general medical units. These are minimums — not targets. Operating consistently at the minimum with high-acuity patients creates patient safety risk that raw headcount data does not capture.

Acuity-adjusted staffing goes beyond headcount. A medical-surgical unit with six patients at LACE score 8+ is not the same staffing burden as six stable post-op patients. Vizier calculates acuity-weighted patient loads by unit and shift, comparing realized staffing against both regulatory minimums and acuity-adjusted targets.

Nationally, the American Nurses Association recommends acuity-based staffing rather than fixed ratios. The majority of states outside California operate under "adequate staffing" standards without numeric mandates — which means the burden of justifying ratios falls on the nurse manager when sentinel events occur. Real-time data is your documentation.

Patient Flow Analytics

Bed Occupancy, Average LOS, and ED Boarding — Tracked Together

Bed Occupancy Rate
Target
80–85%
Alert threshold
> 90%

Above 90% creates patient flow bottlenecks, increases infection transmission risk, and accelerates nursing staff fatigue. Below 75% suggests discharge planning or admission process inefficiencies.

Average Length of Stay
Target
DRG-specific benchmark
Alert threshold
> 110% of DRG mean

LOS more than 10% above DRG mean for a given diagnosis suggests discharge barrier — social work need, equipment unavailability, or post-acute placement delay. Each excess day costs $1,200–$2,400 in variable costs.

ED Boarding Time
Target
< 60 minutes
Alert threshold
> 4 hours

ED boarding — the time between an admission decision and physical transfer to an inpatient bed — drives ED capacity crisis, ambulance diversion, and downstream nursing workload spikes. CMS tracks this under the Hospital Outpatient Quality Reporting program.

Overtime, Burnout & Float Pool Analytics

Overtime at 1.5–2× Base Cost Is a Staffing Model Problem, Not a Budget Problem

Overtime costs 1.5× base rate for hours 40–48, and many union contracts require 2× for weekend and holiday hours. At an average RN base rate of $42/hour, 20 hours of weekly overtime per unit translates to $43,680 per year in premium labor above base — per unit. A 10-unit hospital with this pattern spends $436,800 annually in avoidable premium labor.

Vizier identifies overtime patterns by unit, shift, and day of week — distinguishing structural overtime (chronic understaffing) from event-driven overtime (census spikes). Structural overtime requires a hiring or float pool solution. Event-driven overtime requires predictive scheduling, not more headcount.

Burnout indicators tracked include: consecutive shifts above 12 hours, rolling overtime percentage (weeks where a nurse worked more than 48 hours), reported call-outs correlated with prior overtime, and voluntary turnover patterns by unit. When a unit's turnover rate climbs above 25%, the data usually shows a 6–12 month pattern of excess overtime before the departures begin.
