# Productivity Metrics

## Worked Hours

**Definition:** Total hours actually worked by employed staff in a period, excluding agency hours.

**Source field:** `worked_hours`

**Includes:** Regular hours + overtime hours worked by employed staff
**Excludes:** Agency and temp staff hours (tracked separately in `agency_hours`)

**Notes:**

* Worked hours is the denominator for OT Rate and Agency Rate calculations
* Ensure consistency — if your payroll system includes agency hours in worked hours, exclude them before uploading

## Scheduled Hours

**Definition:** Total hours scheduled for employed staff in a period — the planned capacity.

**Source field:** `scheduled_hours`

**Notes:**

* Scheduled hours represent the staffing plan, not actual coverage
* The gap between scheduled and worked hours reflects unplanned variance (absences, overtime, early departures)
* Required for Absence Rate calculation

***

## Schedule Variance

**Definition:** The difference between actual worked hours and scheduled hours as a percentage.

**Formula:**

```
Schedule Variance = ((worked_hours − scheduled_hours) ÷ scheduled_hours) × 100
```

**Interpretation:**

* Positive variance: Staff worked more than scheduled (overtime-driven)
* Negative variance: Staff worked less than scheduled (absence-driven)
* Large variance in either direction indicates scheduling instability

## Agency Hours

**Definition:** Hours worked by temporary or agency staff in a period.

**Source field:** `agency_hours`

**Notes:**

* Track separately from employed staff hours
* Agency hours are included in total coverage calculations but excluded from employed staff metrics
* High agency hours alongside high vacancy rates confirms the vacancy is being covered by temporary staff

## HPPD — Hours Per Patient Day

**Definition:** Total worked hours (employed + agency) per patient day — a standard clinical productivity measure in acute care.

**Formula:**

```
HPPD = (worked_hours + agency_hours) ÷ census_days
```

**Requires:** Workload data (patient census) uploaded separately to Senzo.

**Benchmarks:** HPPD targets vary significantly by unit type. ICU: 12–18 HPPD. Medical-Surgical: 6–9 HPPD. Emergency: 4–7 HPPD.

**Notes:**

* HPPD is only meaningful when benchmarked against appropriate unit-type norms
* Senzo displays HPPD in the Metrics Explorer when workload data is present
* HPPD below target indicates potential understaffing; above target may indicate overstaffing or inefficiency

## Nurse-to-Patient Ratio

**Definition:** The ratio of nursing staff to patients at a given point in time.

**Formula:**

```
Nurse-to-Patient Ratio = census ÷ (nursing_headcount × shift_fraction)
```

**Notes:**

* Point-in-time calculation — requires census and shift data
* Senzo approximates from monthly averages when real-time data is not available
* Regulatory minimums vary by province and unit type

## Actual vs Budgeted FTE

**Definition:** The difference between budgeted FTE and filled FTE — the gap between planned and actual capacity.

**Formula:**

```
FTE Variance = filled_fte − budgeted_fte
```

Negative variance: Operating below budget (vacancy or budget hold)
Positive variance: Operating above budget (overtime-driven FTE equivalent)
