Planning a care home: 5 common mistakes and how to avoid them

For three years, I’ve been guiding care homes (Swiss medico-social facilities, EMS) on their care organisation. Different sizes: from 40 to 180 beds. Different resident profiles: from purely social to psychogeriatric units.

And yet, on planning, the same five mistakes recur.

None of them is due to lack of competence. The directors and head nurses I meet are experts in their craft. The mistakes are structural: they come from a planning logic that no longer has the right anchor point.

Mistake 1 — Planning from HR constraints, not resident needs

By far the most frequent mistake.

We start with the HR table: who can work when, who is in training, who has booked leave. We fit care presence on top of that. And we discover, at month-end, that some care slots were under-covered — even though we were at the theoretical headcount required.

The problem is that residents don’t consume care uniformly. The morning between 7am and 10am weighs three times more than the afternoon. The 6pm-8pm slot, with high-dependency residents, is under tension.

The right reflex: start by mapping care needs by time slot (90 minutes max). Then confront the HR plan. The real decisions are made in the gap.

Mistake 2 — Confusing rotation and rota

A rota is the sequence of working / non-working days (e.g., 3 on / 2 off / 4 on / 3 off). A rotation is the alternation between time slots (morning, afternoon, night).

We confuse them because the software handles them together. But they don’t obey the same constraints:

• The rota is constrained by cumulative fatigue and labour law.
• The rotation is constrained by care quality (referent continuity) and carer health.

Optimising one without watching the other produces technically legal schedules that produce real distress.

Mistake 3 — Overloading the morning

Morning is the densest slot in a care home. Personal care, transfers, medication, meals, activities. The temptation is to put every available person in the morning.

Consequence: an under-staffed afternoon, and especially a presence debt accumulated for the night. Night in a care home is critical (falls, dehydration, agitation). Under-staffing it compromises the next day’s care quality.

The right reflex: come back to the resident. What are the real demand peaks? Often, in reality, 9am-10:30am and 5pm-7pm, more than the entire morning.

Mistake 4 — Having no documented Plan B

Absenteeism in Swiss care homes averages 8 to 12%. Always. With a 30-person team, you statistically have two to three absences a week.

And yet, Plan B is rarely written. We handle case by case, verbally, in emergency. Result: the hidden cost of replacement (overtime, agency, degraded quality) explodes.

The right reflex: build replacement standards by absence type (short / long, expected / unexpected, weekend / weekday). Document in an A3. Plan B isn’t pessimism. It’s mature planning.

Mistake 5 — Not measuring cumulative fatigue

The most insidious mistake. Tools measure compliance with the collective agreement: 11 hours minimum rest, etc. They don’t measure cumulative fatigue over a rolling 4 weeks.

A team can be compliant and exhausted. This explains a large share of the turnover in care professions.

The right reflex: add a cumulative fatigue indicator to your planning dashboard. Weight nights, weekends, fast rotations. It’s not exact science — but it’s a thousand times better than not doing it.

The tool isn’t the solution

None of these five mistakes is solved by changing tools. They are solved by changing the entry angle: start from the resident, not the schedule. Think the gesture before the timing.

That’s what the Care home planning demo I offer tries to show: a sandbox where you see the effect of each trade-off before imposing it on your teams.

If you’re rethinking your care organisation, I’d be glad to talk. An hour’s conversation is often enough to see where to make the first cut.
