Abstract: Pressure ulcers (PU) are common on stroke patients with immobility. The best turning interval to prevent
PUs development still unknown. The objective of this study was to compare the PUs incidence between
stroke patients turned every 1 h and those turned every 2 h. This study used quasi experiment - post test with
control group design, conducted between January March 2018. Samples recruited within 1-3 days of
admission in neurological ward in two hospital. The experimental group (n=26) was turned every 1 hour
while the control group (n = 23) was done every 2 hours in the day (6 am 6 pm) and every 3 hours in the
night (6 pm 6 am); using 30
o
tilt; continued for the next 5 days. All partisipants (n = 49) were 23 men and
26 women, aging 42-81 y/o. 6/26 patients (23.1%) in the experimental group and 6/23 patients (26.1%) in
the control group developed PUs (p = 1.000; p > 0.05). All PUs were grade 1 (10.2%), grade 2 (12.2%), and
DTI (2%). There was no statistically difference in PUs development over 5 days of turning between stroke
patients those turned at 1 h or 2 h intervals.
1 BACKGROUND
Pressure ulcer incidence is found in stroke patients
with immobility (Amir et al., 2013). Pressure ulcer is
a localized injury in the skin and or the tissues
underneath covering the bone resulting from
pressure or the combination of pressure and shear or
friction (Wiens, 2010; Casey, 2013). Pressure ulcer
caused longer hospitalisation and extra nusing care
(Dealey, et al., 2012), also decreased patient’s health
related quality of life (Thein et al., 2010).
Approximately, more than 2.5 milion patients
hospitalized develop pressure ulcer and 60,000
patients die of the complication of pressure ulcer
(HRET, 2017). Mortality rate due to pressure ulcer
count for 40% annually while patients die after one
year treated with pressure ulcer in hospital count for
60% (Compas 2010 in Tarihoran, et al., 2010). The
highest incidence of mortality resulting from
pressure ulcer occurs in patients aging 75 years old
and septicemia contribute to 39.7% mortality
(Bryant, 2012). Post stroke complication and
mortality increased in patients with pressure ulcer
(Lee et al., 2016).
In Indonesian public hospital, hospital acquired
pressure ulcer reaches 33% in 2007 (Amir, et al.,
2013). The incidence of pressure ulcer of patients
with stroke in ICU & neurological ward in one of
the government hospital in 2011 counted for 10/36
(28%) grade I and 6/36 (17%) grade 2 or higher.
More than 50% of those including patients and
families have been educated while 74% patients
have been repositioned in irregular basis by either
nurses or families (Amir, et al., 2013). Preliminary
study conducted in Stroke Ward of Dr. Ramelan
Military Hospital of Surabaya from April as of
September 2017 found 79 patients developing
pressure ulcer, 56 of whom are patients with stroke
(19 prehospital acquired and 37 hospital acquired).
Pressure ulcer may occur 3 days after skin is
exposed to pressure (Tarihoran, et al., 2010). Several
factor affecting the development of pressure ulcer
include tissue tolerance and pressure (duration and
intensity) (Nursalam, 2016). Factor of pressure is
influenced by decreased mobility, activity, and
sensory perception commoly occurring in patients
with stroke (Bryant, 2012).
Turning every 2 hours is one of the
recommended nursing interventions to prevent the
development of pressure ulcer (Linton, 2012; Miles,
et al., 2014; HRET, 2017) resulting from decreased
mobility and sensory perception in patients with

stroke. However a number of study found that
turning every 2 hours is no longer efficacious to
prevent the development of pressure ulcer
(Ostadabbas et al., 2011; Bergstrom et al., 2013;
Manzano et al., 2014).
Tarihoran, et al. (2010) did turning on patient
with stroke using 30° triangle pillow for 2 hours
interval toward the strong side, 2 hours supination,
and 1 hour toward the weak side, but there was one
patient developing pressure ulcer at sacrum. Study
conducted by Ostadabbas et al. (2011) found that
patients on supine position must be turned within
less than 1 hour. In early 20 century, several books
recommended more frequent turning despite limited
research (Casey, 2013). Reddish body part and or
weak/paralised body part must not be in the same
position for > 30 minutes (Linton, 2012). Demol et
al. (2013) found that the size and severity of deep
tissue injury (DTI) can be reduced by shortened the
repositioning interval. Therefore researcher tries to
shorten turning interval for every 1 hour, 30° lateral
turning position with one pillow and 30° head
elevation in supine position. Shorter turning interval
can reduce duration pressure, 30° lateral position can
reduce pressure intensity while 15-30° head
elevation during supination prevent shear and
pressure against sacrum. This study aims to analyse
the difference of pressure ulcer incidence on patient
with stroke who were turned every 1 hour and 2
hours.
2 METHODS
2.1 Design
This study used quasy experiment - post test with
control group design. This study hypothesis that
there is different incident of pressure ulcer on
patients who were turned every 1 hour opposed to 2
hours.
2.2 Sample
Samples of this study were stroke patients treated in
Neurological Ward of Dr. Ramelan Military
Hospital of Surabaya and Flamboyan Ward of
General Hospital of Jombang for three months (1
January 1, 2018 March, 31 2018) meeting
inclusion criteria. Sample size was 54 patients;
intervention group (n = 27) and control group (n =
27).
2.3 Inclusion and Exclusion Criteria
The main inclusion criteria of this study were stroke
patient adults who were; suffering from immobility,
Braden scale 18, absence of pressure ulcer,
absence of anasarca edema, stable hemodynamic
(systolic blood pressure 100 mmHg), recruited
within 1 3 days of admission in neurological ward.
Exclusion criteria were; restless, having diagnosed
or suspected spinal/ cervical injury/ brain death, on
critical condition, and presence of pressure ulcer at
admission/ before intervension started. Patients were
dropped out if passing away/discharge/moving to
other ward, patient’s condition suddently
deteriorated/ hypotension, and refused to continue
the procedure before intervention was complete (5
days).
2.4 Procedures
Two sample groups were turned by researcher
helped by an assistant. Control group was turned by
using 30° tilt (right side, back, left side, back)
supported by a pillow on the back every 1 hour in
the day (6 am 6 pm) and every 3 hours (supination
and turned to the strong side) at night (6 pm 6 am).
Control group was turned 30° tilt (right side, back,
left side, back) supported by a pillow on the back
every 2 hours in the day (6 am 6 pm) and every 3
hours (supination and turned to the strong side) at
night (6pm 6am).
Pressure ulcer risk assessment used Braden scale.
Result of systematic review meta analysis showed
that Braden scale was more valid for general
population with 87.42% sensitivity and 90%
reliability (García-Fernández, et al., 2013). Similar
studies found that should it be seen from >14 score,
Braden scale would range from 82.4%-100% while
specificity < 15, it wolud range from 72.7%-81.8%.
By using cut of point 15, validity at Braden scale
prediction would be sensitivity 88.2%, specificity
72.7%, FP 27.3% and FN 11.8%, and area beneath
ROC curve was 0,880 (Kale et al., 2014).
Development of pressure ulcer was evaluated
every time the position was changed until 5 x 24
hours using EPUAP-NPUAP 2014 pressure ulcer
grade classification.
2.5 Analysis
Statistical tests utilized were; Chi-Square to figure
out the difference of pressure ulcer incidence
between stroke patients turned every 1 hour and 2
hours; Mann Whitney to compare the difference of

PU grade classificatin between two groups.
Statistical significance was set at the 5% level <
0.05).
2.6 Ethical Considerations
This study has gained approval of ethical eligibility
from ethic commission of health research Dr.
Ramelan Military Hospital of Surabaya number
01/EC/KERS/2018. All informed consents were
signed by the families.
3 RESULTS
Fithty nine patients selected for eligibility with
consecutive sampling, 10 patients were dropped out
due to; discharge (3), moving to the other ward (1),
and passing away (6) before intervention was
complete, leaving a final study sample of 49
patients, who were assigned to intervention group (n
= 26) and control group (n = 23).
Participant distribution ranges from 42 to 81
years old with average age of intervention group
(63.77 years old) and control group (67.26 years
old); infarcted stroke (65.3%) and hemorrhagic
stroke (34.7%); men (46.9%) and women (53.1%);
braden scale > 9 (87.8%) and 9 (12.2%); albumin
level < 3mg/dl (6.1%) and ≥ 3 mg/dl (93.9%) (Table
1).
3.1 Incidence of Pressure Ulcers
Pressure ulcer occurred in both group i.e., 6 patients
(intervention group), 6 patients (control group, and
37 patients no pressure ulcers development were
found (Table 2).
The incidence of pressure ulcer in intervention
group was 6/26 (23.1%) which included 2 patient
developing grade 1 PU on sacrum and tight; and 4
patients developing grade 2 PU on buttocks. The
incidence of pressure ulcer in control group was
6/23 (26.1%) which included 3 patients developing
grade 1 PU on buttocks and trochanter; 2 patient
developing grade 2 PU on buttock, tight, and
shoulder; 1 patient developing deep tissue injury PU
on the tight (Table 2 & 4).
Result of Chi - Square test shows no statistically
difference of pressure ulcer incidence between
intervention group and control group (p = 1.000 or p
>0.05) (Table 2). There was no statistically
difference of pressure ulcer grade classification
between stroke patients who were turned every 1 h
and those turned every 2 h (p>0.05) (Table 3).
This study found that 12/49 patients who
developed pressure ulcer, 7/12 (58.3%) had it in the
buttocks, 1/12 (8.3%) on sacrum, trochanter (2),
tight (3) and left upper arm (1) (Table 4).

4 DISCUSSION
4.1 Age & Gender
Five patients (41.7%) developed pressure ulcer were
aged 71 years old; 3 patients (25%) were aged 60-
70 years old; and 4 patients (33.3%) < 60 years old
(Table 4). Previous study revealed that no significant
association between age and development of
pressure ulcer, but indicate risk. Patients aging 71
years old were 0.8 times greater to suffer from
pressure ulcer (Tarihoran et al., 2010). Pressure
ulcer was significantly increased poststroke
mortality in patients aged 60 years or older (Lee et
al., 2016). Pressure ulcer incidence in elderly can
increase risk for mortality and reduce quality of life
(Khor, et al., 2014).
According to the distribution of sex of PU
development, 12 patients developed PU (6 women; 6
men). It show equal incidence of pressure ulcer both
in men and women (50% : 50%). Pressure ulcer was
correlated with poststroke mortality and
complications in men and women (Lee et al., 2016).
Haast et al. (2012) suggested that women are a
higher risk for bad prognosis such as decreased
quality of life and increased risk for post stroke
depression compared to men.
4.2 Incidence of Pressure Ulcer
This study revealed no difference in pressure ulcer
development between stroke patients turned every 1
hour and those turned every 2 hours. The study
hypothesis was rejected. Previously, there was no
study which turned patients every 1 hour.
The previous studies compared the turning
interval every 2 hours with 3, 4, or 6 hours. A study
conducted by Bergstrom et al. (2013) statistically
revealed no difference in pressure ulcer incidence on
patients who were turned every 2, 3 and 4 hours. A
study conducted by Manzano et al. (2014) also
found no difference in pressure ulcer incidence
between patients who were turned every 2 hours and
4 hours. Result of systematic review cannot prove
the best interval between 2 h vs 3 h, or 4 h vs 6
hours (Gillespie, et al., 2014).
Demol, et al. (2013) conducted a study by
comparing 4 turning interval; every 2, 3, 4, and 6
hours over degree of DTI. The study revealed degree
and extent at deep tissue injury could be reduced by
shortening the turning interval.
Still et al. (2013) conducted an experiment at
turning team who did the turning every 2 hours
around the clock on patients with stable
hemodynamic condition. The study found that
turning every 2 hours by employing a turning team
could reduced pressure ulcer incidence from 15.1%
(before) to 5.24% (after).
No discrepency of pressure ulcer incidence on
both groups turned every 1 h and 2 h resulted from
turning which was not carried out in 24 hours. In the
day (6 am 6 pm) turning was done every 1 h
(intervention group) and 2 h (control group) while at
night (6 pm 6 am) turning was performed every 3
hours. Night turning was carried out every 3 hours
aimed to minimize disturbing sleeping time because
sleeping and rest is important for recovery process
(Latimer et al., 2015). A study conducted by Moore
et al. (2011) found that turning every 3 hours at
night with 30° lateral tilt reduced pressure ulcer
incidence by 67% than those turned every 6 hours
with 90
o
lateral rotation (Moore & Cowman, 2012).
According to a study by Ostadabbas, et al. (2011)
body can maximum tolerate supine position for 1
hour. Erythema can develop within 1-2 hours on
person with healthy skin and adequate circulation
(Linton, 2012). Ischemic stroke affecting motor
cortex leads to weakness/ paralysis on the muscle
innervated by the nerve; as a result, muscle
contraction weakens or loses. If the paralysed or
weak area is underneath and is under prolonged
pressure, it will potentially lead to develompment of

pressure ulcer (Pendit, 2017). Therefore, paralysed
area must not be at similar position for 30 minutes
(Linton, 2012).
An experimental study found that ischemia for at
least 90 minutes lead to organ and root fiber
damage. Prolonged ischemia may reduce adenosine
triphosphate (ATP) and compromise cellular
activities leading to necrosis and subsequent
pressure ulcer (Casey, 2013).
4.3 Location of Pressure Ulcer
This study found only 1 of 12 patients who
developed pressure ulcer at sacrum. Reduced
incidence of pressure ulcer on sacrum due to 30°
lateral position allows distribution of pressure in
wider areas (Nursalam, 2016), and can reduce
pressure against sacrum (Miles et al., 2013).
According to Yoshikawa, et.al. (2015) sacrum is in
intense contact with the surface of the bed during
supination. 3 and 40° lateral position can
minimize contact with the surface of the bed.
This study also found that 7/12 (58.3%) patients
developed pressure ulcer in the buttocks. Different
from theory proposed by Bryant (2012) and
Nursalam (2016) stating that the most frequently
affected areas include sacrum (28.3%), heel
(23.6%), dan buttocks (17.2%). Miles et al. (2013)
found that the most affected area include sacrum,
buttocks, and heel.
Previous studies show no significant association
between body mass index (BMI) and pressure ulcer
incidence, but indicate risk, for patients with BMI <
18 at risk for 0.8 time to develop pressure ulcer
(Tarihoran et al., 2010). People with lower BMI lead
to have extending bone more than those with higher
BMI. However, the prevalence of pressure ulcer is
higher in patients with lower BMI as well as in
patients with low or obesed weight (Kale et al.,
2014).
The latest study found significant association
between buttock shape and risk for pressure ulcer,
round and square buttocks have significant influence
over higher BMI and Waterlow Risk Assessment
scores (Dunk & Gardner, 2016). Other factors likely
to contribute to the development of pressure ulcer in
buttock area include buttock shape correlated with
higher BMI, moisture, and duration of supine
position (3 hours at night). Higher BMI than normal
with round and square buttock shape leads to
pressure against buttock during supination. In
addition, buttock still touches the bed despite 30°
lateral position (supported by 1 pillow on the back).
All patients in this study used diapers. Using diapers
leads to more moisture area. HRET (2017)
suggested not to use diapers when laying down on
the bed to prevent pressure ulcer. Review conducted
by Coleman, et al. (2013) found 3 most contributing
factors in the development of pressure ulcer which
include mobility/activity, perfusion, condition of
skin/pressure ulcer. Skin moisture, age, nutrition,
hematology are also the contributing factors, but are
not as frequent as the three factors mentioned.
4.4 Limitations
This study has some limitation. Both groups were
not turned with equal interval for 24 hours. At night
turning was done every 3 hours at 6pm 6am to
prevent from disturbing the patients during sleep
(ethical consideration). Therefore, the incidence of
pressure ulcer was likely to occur due to length
turning interval at night. Small number of sample is
less strong for generalization. Patients using diapers
can be bias in whether pressure ulcer was caused by
pressure or moisture caused by diaper.
5 CONCLUSIONS
Turning every 1 hour is not better than 2 hours to
prevent the development of pressure ulcer. In
addition to turning, other factors deserve
consideration such as turning duration at night,
material of the mattress, moisture, body and room
temperature as well as diaper utilization. Turning
every 2 hours can still be done in clinical practice as
long as no latest study suggesting the better turning
interval. Further studies with more samples and
equal turning interval for 24 hours are needed.
