Every two hours

 When Did “Turn Every Two Hours” Become the Standard?

If you’ve ever spent time in a hospital or nursing home, you’ve probably heard it.

“Turn every two hours.”

It’s one of the best-known “rules” in healthcare.

But have you ever wondered…

Where did it come from?

I did.

And what I discovered surprised me.

The practice became widely adopted in the 1940s and 1950s, particularly after World War II as specialized spinal cord injury centers began developing better ways to prevent pressure injuries.

Frequent repositioning clearly helped.

Over time, two hours became a practical schedule.

It was easy to teach.

Easy to remember.

Easy to document.

Eventually, it became the standard.

But here’s what’s interesting.

Researchers who later looked back at the history found that no one has identified strong scientific evidence that exactly two hours is the ideal interval for every person.

In fact, one historical review noted an anecdotal explanation that the two-hour interval may have reflected the amount of time it took nurses in the Crimean War hospitals to work their way down one side of a ward and back up the other.

Florence Nightingale herself wrote about preventing bedsores and managing positioning.

She did not prescribe turning every two hours.

So what began as a practical guideline gradually became viewed as a universal standard.

Today, pressure injury experts increasingly recognize something important.

People are different.

Modern guidelines encourage individualized repositioning plans based on the person’s:

• medical condition

• circulation

• sensation

• nutrition

• support surfaces

• ability to move

• comfort

• and overall risk.

That makes sense.

Because repositioning has never really been just about preventing pressure sores.

Movement supports the whole person.

For Alex, repositioning may help:

• breathing

• secretion mobilization

• circulation

• digestion

• joint health

• muscle length

• comfort

• autonomic regulation

• and simply feeling better.

When Alex is in his wheelchair, I tilt him back about every hour.

In bed, he is often adjusted much more frequently than every two hours.

Not because we’re ignoring a guideline.

Because we’re responding to his body.

Sometimes he needs repositioned because of secretions.

Sometimes because he’s uncomfortable.

Sometimes because of spasms.

Sometimes because his breathing changes.

Sometimes because he simply says,

“Can you adjust me?”

That request is not separate from his medical care.

It is part of his medical care.

One of the biggest lessons I’ve learned over the past twenty-one years is this:

Guidelines provide a place to begin.

The individual teaches us where to go from there.

Good clinicians understand the principle behind the guideline.

Great clinicians thoughtfully individualize its application to the person in front of them.

Perhaps that’s true of much of healthcare.

Not abandoning standards.

Understanding why they exist…

and then applying them wisely to the unique human being receiving the care.

Because in the end…

Repositioning should not be reduced to a pressure-ulcer-prevention task.

Movement supports the whole person.
