Labor Productivity and Food Cost in a 220-Bed Hospital
St. Alban's is a 220-bed community hospital averaging 180 inpatients; 75% are on oral diets and receive three trays daily. The department also runs a cafeteria with 700 transactions per weekday (3,500 transactions per week budgeted). Staffing is 26.4 FTEs, each budgeted 40 hours per week; 4.2 of those FTEs are clerical/diet-office positions. Labor is running 4.8% over budget year-to-date. Cafeteria food cost is 34% of $610,000 in sales against a 30% target. Administration has asked for a 5% labor reduction without reducing tray accuracy or food quality, and the director has proposed moving to room service with a 12-hour order window and on-demand tray assembly.
1. Calculate meals per labor hour and interpret it. What must you verify before making cuts?
Read the worked answer
Labor hours per day = (26.4 FTE × 40 h) ÷ 7 = 150.9 hours/day. Daily meals: 180 patients × 3 trays = 540 patient meals; plus 700 cafeteria transactions = 1,240 total.
- Combined: 1,240 ÷ 150.9 = 8.2 meals per labor hour
- Patient trays only: 540 ÷ 150.9 = 3.6 meals per labor hour
Against a typical hospital benchmark of roughly 12–15 combined MPLH, the department is well under, so there is real room - but verify four things first: (1) whether clinical dietitians and the 4.2 clerical FTEs are inside the productivity denominator (they should not be in production MPLH); (2) whether a cafeteria "transaction" is a full meal or a coffee, since the two inflate the numerator differently; (3) weekend and holiday volume, which is lower and drags the average; (4) the source of the 4.8% overrun - overtime and agency coverage are fixable without cutting positions, while an inflated FTE base is not. Comparing an unadjusted MPLH to a benchmark is how departments cut the wrong jobs.
2. Evaluate the room service proposal against the 5% labor target.

The 5% target is 26.4 × 0.05 = 1.32 FTE, or about 53 hours/week.
Room service does not simply subtract labor; it redistributes it. Batch trayline assembly shrinks, but you add order-taking and call-center coverage, on-demand short-order production across a longer window, and more delivery trips with fewer trays per cart. At 180 beds, the volume is small - you do not get the scale that makes room service efficient in a 500-bed hospital, and you may need additional staffing to cover a 12-hour window that the current schedule does not span.
The realistic gains are food cost (batch overproduction falls, often 20–30%) and patient satisfaction, not labor. Recommend a 90-day pilot on two nursing units: one FTE redeployed from trayline to order-taking, with tracking of trays per labor hour, tray accuracy, late trays, and patient satisfaction. If trays/hour and accuracy do not improve, the pilot costs little and the 1.32 FTE must come from elsewhere - most plausibly overtime control and consolidating the 4.2 clerical FTEs through diet-office automation.
3. Quantify the food cost variance and name two interventions with their expected effect.
Read the worked answer
Excess food cost = (0.34 − 0.30) × $610,000 = 0.04 × $610,000 = $24,400 above target for the period. That is a larger dollar figure than the labor gap is likely to yield, and it is where I would look first.
1. Production forecasting and batch cooking. Overproduction is the most common driver of a 4-point variance. Track overproduction and waste by item for four weeks, then cook to forecast in two batches rather than one. A 25% reduction in waste on the affected items typically recovers several thousand dollars per quarter and requires no capital.
2. Menu engineering and purchasing. Rank cafeteria items by contribution margin; raise the visibility of high-margin items, re-price or drop the chronic losers, and re-bid the prime vendor with actual usage data. A 1-point improvement in food cost is worth $6,100 per period.
Supporting step: separate patient-food cost from cafeteria cost. Blending them hides whether the variance is retail or clinical, and cutting the wrong one damages the service administration asked you to protect.
