Sit-to-stand and standing aids

Between the patient who needs a full-body lift and the patient who can walk with supervision there is a large group who can do part of the work themselves. They can sit on the edge of the bed, take some weight through their legs and hold on with their hands, but they cannot stand up and turn safely on their own. On 4 West and at Maple Court, this group is often the largest of all, and it is the group most often moved by hand, because staff think of them as "almost independent". The 3 East injury in Lesson 1 was a patient of this kind.

This lesson covers the equipment for this group: powered sit-to-stand aids, non-powered standing and turning aids, gait belts, and walking slings and vests. It explains who each one is for, who it is not for, how it is used, and why getting these patients up with equipment is good for their recovery as well as for staff.

Powered sit-to-stand aids

A powered sit-to-stand aid, sometimes called a standing lift or stand assist lift, is a wheeled machine with a footplate, a pad that the patient's shins or knees rest against, handles to hold, and a powered arm that raises the patient from sitting to standing using a sling or belt around the lower back. The patient helps by taking weight through their legs and holding on; the machine does the lifting and keeps them from falling.

A sit-to-stand aid is right for a patient who:

• can bear weight through at least one leg, at least for a short time;
• can sit on the edge of the bed or chair with little or no support;
• can hold on with at least one hand;
• can follow simple instructions and is reasonably calm; and
• reaches level 3 on the bedside mobility assessment (Lesson 3), or level 2 with some weight-bearing.

It is not right for a patient who:

• cannot bear any weight, or has a fracture, recent surgery or pain in the legs or hips that stops them standing;
• cannot sit upright or hold their head up;
• is very confused, agitated or likely to let go or push backwards;
• has severe contractures that stop the feet going flat on the footplate or the knees meeting the pad;
• has shoulder problems or fragile skin under the arms, because some standing slings pull up under the armpits; or
• is too tired, dizzy or unwell to stand today.

Patients who fall outside these limits need a full-body lift. As always, the assessment can move the plan toward more support, never less.

Using a sit-to-stand aid

• Prepare. Check the care plan, the aid (inspection tag, battery, brakes, controls) and the sling. Explain the move. Make sure the patient is wearing non-slip footwear or has bare feet if the plan says so.
• Position. Help the patient sit near the edge of the bed or chair, with feet flat and hip-width apart. Bring the aid in, open the base legs if needed, and place the patient's feet on the footplate with the shins against the pad. Put the aid's brakes on if the manufacturer says to for standing.
• Fit the sling. Place the standing sling around the patient's lower back, below the shoulder blades and above the waist, and fasten it as the design requires. Attach the sling to the arm with the loop lengths in the plan.
• Stand. Ask the patient to hold the handles and lean slightly forward. Raise them slowly with the hand control while encouraging them to push up with their legs. Stop when they are upright and check: are they comfortable, steady and alert? Is anything pulling under the arms?
• Move. Release the brakes and move the aid slowly to the chair, commode or toilet. Keep the patient upright and close to the aid, and do not travel far.
• Sit. Position the chair behind the patient, put its brakes on, and lower the patient slowly while the second worker guides them back into the seat.

Two staff are present for sit-to-stand transfers at Northbridge unless the patient's care plan says one is enough, which is common for stable residents who use the aid every day. Patients should be kept standing only as long as the task needs. Signs of trouble are dizziness, sweating, pallor, breathlessness, the knees buckling or the patient letting go; the response is to lower them straight back to the bed or chair.

Non-powered standing and turning aids

A non-powered standing aid, often called a stand-and-turn aid or rotating platform, has a footplate that turns, a knee pad and a frame with a bar to hold. The patient pulls themselves up to standing using the bar, with staff supervising and guiding. The worker then turns the platform so the patient faces the other way, and the patient sits down on the chair or commode behind them. No lifting is done by the worker; the patient's own strength does the standing.

Because the patient must be able to stand up with only a little help, these aids are for patients who can already stand but cannot step and turn safely, typically level 4 on the bedside assessment. They are light, quick to use and good for short transfers such as bed to commode at night. They are not a substitute for a powered aid when the patient cannot stand up without being pulled.

Gait belts and transfer belts

A gait belt, also called a transfer belt, is a strong belt fastened around the patient's waist over clothing, usually with handles. It gives staff a secure place to hold a patient who can stand and walk, to steady them, guide them and help them keep their balance. It is a useful tool, and Northbridge's policy requires one for every patient who walks with staff assistance.

A gait belt is not a lifting device. It does not reduce the weight of the patient; it only gives the worker something to hold. When it is used to pull a patient up from a chair or to take their weight as their knees buckle, the worker is doing a manual lift, with the load held at arm's length and often with a twist. That is exactly what happened on 3 East. The rule at Northbridge is simple: a gait belt is for steadying, not for lifting. If a patient needs to be pulled up, they need a sit-to-stand aid. If a patient starts to fall while wearing a gait belt, the belt is used to guide them down, not to hold them up, as Lesson 8 explains.

Walking slings and vests

Getting patients walking again is one of the main goals of hospital care. Walking prevents the loss of strength and balance that comes with bed rest, and it shortens stays. But walking a weak patient is one of the riskiest tasks for staff, because the patient may fall at any moment and the natural reaction is to catch them.

Ambulation vests and walking slings solve this by attaching the patient to a ceiling lift or a floor lift designed for walking. The vest fits around the chest and the lift takes up the slack, so that the patient walks under their own power but cannot fall. If their knees buckle, the lift holds them, and staff can lower them into a chair or back to bed. With a room-covering ceiling track, a patient can walk the length of the room, and some units have track in a corridor or therapy area for longer walks.

At Northbridge, physical therapists lead the early walking of post-operative and stroke patients, and the new program added walking vests to 4 West and 3 East. Grace's argument for them was partly about staff safety and partly about patients: with the vests, nurses walked patients more often between therapy sessions, because they were no longer afraid of a fall.

How many sit-to-stand aids does a unit need?

4 West had one powered sit-to-stand aid, shared with 3 East. Grace suspected that this was why so many level 3 patients were moved by hand. She took the bedside mobility levels recorded each morning for two weeks and counted how many level 3 patients each unit had each day, then estimated how many sit-to-stand transfers that meant.

# Level 3 patients each morning on 4 West and 3 East over 14 days
west = [7, 9, 8, 6, 10, 8, 7, 9, 11, 8, 7, 6, 9, 10]
east = [5, 4, 6, 7, 5, 6, 4, 5, 6, 7, 5, 4, 6, 5]
TRANSFERS_PER_PATIENT = 6      # bed, chair, toilet and back, per day
MINUTES_PER_TRANSFER = 5       # including fetching the aid
AID_HOURS_AVAILABLE = 14       # 0700 to 2100, when most transfers happen

daily = [w + e for w, e in zip(west, east)]
avg = sum(daily) / len(daily)
need_minutes = avg * TRANSFERS_PER_PATIENT * MINUTES_PER_TRANSFER
aids_needed = need_minutes / (AID_HOURS_AVAILABLE * 60)
print(f"average level 3 patients per day: {avg:.1f} (max {max(daily)})")
print(f"sit-to-stand minutes needed per day: {need_minutes:.0f}")
print(f"aids needed if used at 100 per 100 of available time: {aids_needed:.1f}")
print(f"aids needed at 50 per 100 use (to avoid queues): {aids_needed / 0.5:.1f}")

average level 3 patients per day: 13.6 (max 17)
sit-to-stand minutes needed per day: 407
aids needed if used at 100 per 100 of available time: 0.5
aids needed at 50 per 100 use (to avoid queues): 1.0

The two units together averaged about 14 level 3 patients a day, needing about seven hours of sit-to-stand time. A single aid could in theory cover that, but only if it were in use for half of every hour of the day and always in the right place. Equipment that is in use half the time means that the next person who needs it usually has to wait, and on a busy unit waiting turns into a manual lift. Grace recommended at least two aids for each unit, which the committee approved in the next budget, and the number of standing transfers done by hand on the two units fell sharply.
