Low mobility/bedrest is a common occurrence in
hospitalized patients
Functional decline is the leading complication of
hospitalization for the elderly (occurs in 34-50% of
hospitalized older adults)
– Deconditioning and functional decline was found to occur by
day 2 of hospitalization
– Comparison of functional status at baseline and day 2 in 71
hospitalized pts >age 74 showed declining ability in: mobility,
transfer, toileting, feeding, and grooming.

Deconditioning + physiologic changes 2/2 bed rest 
declining ability to perform ADLs / functional decline
› Functional decline increased LOS, increased mortality,
increased institutionalization and need for longer rehab and
home health services, increased healthcare costs.

This leads to previously independent patients being d/c’d
to SNF!

Older people who develop new functional
deficits during hospitalization are less likely
to recover lost function.
 One study: 1279 older adults (>70yrs)
hospitalized for acute medical illness.

› 31% had decline in ADLs at discharge compared
with pre-admission baseline.
› At 3 months, 51% of original study sample
reported new ADL/IADL disabilities (40%)
compared with pre-admission, and 11% had
died.

Bed rest can contribute to development
of delirium.
 Delirium is independently associated with
worse outcomes, longer hospital stay,
higher cost, increased risk of death, and
with greater degrees of cognitive
decline.
 Delirium  increased risk of needing d/c
to SNF!

Study of 162 pts, age >/= 65, admitted for acute
illness, hospital stay at least 2 days.
Placed step activity monitors on all pts. Calculated
step change score between day 1 and day 2.
Results: Adjusted mean difference in LOS between
those who increased their step total by >/= 600
steps was 2.13 days (95% CI, 1.05-3.97).
600 steps corresponds to approx 12 min of slow
walking.
Limitations: observational only. Pts who increased
their step count may have been less ill.

Study looked at 458 pts with CAP admitted to medicine
wards (3 hospitals).
Group randomized trial
Intervention: EM defined as sitting OOB or ambulation at
least 20 min within 1st 24 hrs of hospitalization, with
progressive mobilization on each subsequent hospital
day
Results: next slide. Also noted non-statistically significant
decrease in hospital costs, approx $1000 per pt.
Conclusions: EM of hospitalized patients with CAP
reduces overall hospital length of stay and institutional
resources without increasing the risk of adverse
outcomes.


Results:
› Intervention and control groups were similar: age, gender,
disease severity, door-to-drug delivery time, IV-to-po
switchover time.
› Hospital LOS significantly less (mean, 5.8 vs 6.9 days;
adjusted absolute difference, 1.1 days; 95% confidence
interval, 0.0 to 2.2 days).
› There were no differences in adverse events or other secondary
outcomes (mortality, re-admissions, ED visits, #CXRs)
between treatment groups.
Study with n= 50 pts, adults >/= 60 yrs, admitted
with medical dx, LOS 3+ days, cognitively intact, no
significant physical impairments.
 Compared 2 units (no RNs crossed units).
 Intervention: RNs on tx unit had training including
mobility protocol.
• Measures: Calculated modified Barthel Index (BI)measures capability to do ADLs/functional status
and Up and Go test. Also looked at LOS.

•Scores for Up and Go test not significantly
different between groups (Treatment group: 1.16
admission, 1.04 discharge. Control: 1.35
admission, 1.17 discharge.)
•Treatment group: significantly shorter LOS
(4.96 days treatment vs 8.72 days control;
P<0.001)
Compression and walking versus bed rest in the

Lower overall pain scores.
Significant reduction in leg swelling (lower leg circumference).
Reported significantly improved clinical symptoms including less
pain during walking, reduced pain associated with the sole of the
foot and palpation of the foot.
Less subfascial edema, prefascial edema, a lower skin temperature,
and reduced redness/cyanosis of the affected limb.
Long-term follow-up study of 37 of the 45 original medical
patients (2 yrs later).
Although not statically significant, a lower percentage of
patients in the early ambulation group had swelling (increased
leg circumference) in the affected limb (16/26 early
ambulation group vs 9/11 in the bed-rest group).
A significantly lower percentage of patients in the early
ambulation group (18/26 vs 2/11 in the bed-rest group) had no
symptoms of post-thrombotic syndrome (a significant
complication of DVT).

Study: quality improvement project; evaluated 6 mo period on unit preand post-intervention. All pts for colorectal and urologic surgeries with
no contraindication for ambulation included (n= 1878 pre-intervention,

Intervention: Revising orders, measuring/posting distances on the units,
creating fields in EMR to display ambulation distances, education of
staff, improving dashboard on EMR for easy monitoring of ambulation.

Implementation of the PUMP Plus increased mobility among neurointensive care unit patients by 300% (p <
0.0001).
Reduction in neurointensive care unit length of stay (LOS; p < 0.004), hospital LOS (p < 0.004), hospitalacquired infections (p < 0.05), and ventilator-associated pneumonias (p < 0.001), and decreased the
number of patient days in restraints (p < 0.05).
Additionally, increased mobility did not lead to increases in adverse events as measured by falls or
inadvertent line disconnections.
No difference in falls

Decreased LOS
 Decreased hospital complications
 Decreased cost
 Improved quality of life (and less d/c to SNF)


Implementation does not require significant
cost, and does not cause any adverse
effects (e.g. no increase in falls - may even
prevent falls).



UNM has longer LOS for similar diagnosis compared
to other hospitals.
MDs focus on treatment (meds)
Hospital culture with decreased focus on
mobility/functional status  most of our medicine
patients stay in bed
› We keep patients in bed for fear of increased falls



Our patients develop functional decline over
hospital course. Often MD does not notice until
day of d/c  prolonged stay, more pts need
placement.
Over-reliance on PT for ambulation. In most
hospitals, this is RN-driven initiative.
Other thoughts?

On 7 medicine teams, 8 patients
reported to be remaining in the hospital
“solely for PT/OT needs.”

PT/OT input on how we can help them
maximize their impact

Ideas on how to achieve this?
› What can we as providers do?
› What system processes can we implement?

Most likely RN-driven mobility protocols
› Utilizing techs or other support staff for
ambulation
› Utilizing PT/OT for more complex issues

Things MDs can do to help:
› Activity orders- don’t write bed rest
› D/c Foley
› Judicious use of telemetry (we lack wireless
telemetry)
› Don’t keep isolation patients in their rooms (they
can walk with gowns)

Meta-analysis of 5 studies comparing outcomes of pts with DVT, PE, or both
managed with bed rest vs early ambulation in addition to anticoagulation.
RESULTS: The 5 studies retained in this analysis included a total of 3048 patients.
When compared to bed rest, early ambulation was not associated with a higher
incidence of a new PE (RR 1.03; 95% CI 0.65-1.63; p=0.90). Furthermore, early
ambulation was associated with a trend toward a lower incidence of new PE and
new or progression of DVT than bed rest (RR 0.79; 95% CI 0.55-1.14; p=0.21) and
lower incidence of new PE and overall mortality (RR 0.79; 95% CI 0.402-1.56; p=0.50).
CONCLUSIONS: Compared with bed rest, early ambulation of patients with DVT, PE
or both, was not associated with a higher risk of progression of DVT, new PE or
death. This meta-analysis does not support the systematic recommendation of bed
rest as part of the early management of patients presenting with DVT, PE of both.
