Patient‐Reported Outcomes
• What are they?
‘a measurement of any aspect of patient’s health
status that comes directly from the patient (i.e.,
without the interpretation of the patient’s
responses by physician or others)’
– FDA, 2006
PROs: why
such
interest?
• Provide clinically valuable information about
the patient’s experience with treatment or
disease‐related care
• Symptoms
• Toxicities
• Burden

http://slidepdf.com/reader/full/from-pain-to-sleep-listening-to-patient-reported-outcomes 7/33
Distinguishing Fatigue in its Age‐
Related forms
• One of 10 monitored symptoms: Fatigue was rated
as most prevalent and distressing
• Two‐site Fatigue Scholars’ Program (Oncology
Nursing Society)
– Conceptual Definitions
– Instruments
What is
fatigue?
• Cancer‐related fatigue (focus groups,
individual interviews, concept analysis)‐ – In 7 to 12 year olds: a profound sense of being weak or
tired, or of having difficulty with movement such as
arms or legs too heavy to life and eyes to heavy to open.
» Hinds, Hockenberry ‐Eaton, Gilger et al., 1999
– In 13 to 18 year olds: a changing state of
exhaustion that is a physical condition, at other
times a mental
state,
and
at
other
times
a
combination of physical, emotional and mental
tiredness» Hinds, Hockenberry ‐Eaton, Gilger et al.,1999

treatment)
– Collins et al., 2002; Hinds et al., 1999
– During treatment (significantly increased during reinduction for ALL and
during hospitalizations)
– Hockenberry et al., 2003; Hinds et al., 1990; Hinds et al, 2007
– Up to 23 years following treatment (most distressing)
– Crom et

Benefits of Actigraphy
• Small and innocuous
• Able to attach to wrist or ankle for prolonged periods of
time- able to assess motion and thus sleep patterns
overtime
• Provides continuous activity data with little interference
or limitations imposed on the subject
• Can be used in the home environment
• Does not require ongoing monitoring by professionals• Cost effective
American Academy of Sleep Medicine
Recommendations
• Actigraphy has proven useful for
delineating sleep patterns and
documenting treatment response in
normal children, as well as in special
populations
Morgenthaler et al(2007)

http://slidepdf.com/reader/full/from-pain-to-sleep-listening-to-patient-reported-outcomes 15/33
The first
Intervention
• Enhanced Activity in Hospitalized Children
with Cancer
• 2‐site, randomized pilot study
• 27 patients with a solid tumor or AML
diagnosis admitted for chemotherapy
• Peddling twice daily for 20 minutes
• Intervention successfully delivered 85.4% of
scheduled times
8/14/2019 From Pain to Sleep: Listening to Patient-reported Outcomes
http://slidepdf.com/reader/full/from-pain-to-sleep-listening-to-patient-reported-outcomes 16/33
The first Intervention
• Trend towards the activity arm having better quality
sleep (more efficient) (F=4.17, p=0.053)
• Children experiencing 19 or more nocturnal
awakenings were significantly more fatigued the
next day
• Children with higher nocturnal awakenings had
longer
sleep
duration
(F=6.35,
p=0.0007)
Dexamethasone (DEX), Sleep and
Fatigue
• Examining treatment influences on fatigue
and sleep in children with ALL
• Study purpose:
– To assess the relationship between systemic
exposure to DEX and sleep quality and fatigue in
patients with ALL during continuation
8/14/2019 From Pain to Sleep: Listening to Patient-reported Outcomes
http://slidepdf.com/reader/full/from-pain-to-sleep-listening-to-patient-reported-outcomes 17/33
DEX, Sleep and Fatigue
• Two hypotheses:
– 1. DEX contributes to changes in sleep efficiency,
actual sleep minutes, sleep duration, nocturnal
awakenings, total daily sleep minutes, and daily
nap minutes and to increased fatigue
– 2. patient age, sex and ALL risk category influence
the extent
of
change
in
sleep
and
fatigue
observed during DEX treatment

• Age: teens were in bed less time on DEX and had
slept fewer minutes
• Risk group: significantly associated with sleep
efficiency, actual sleep minutes and nocturnal awakenings, but not with fatigue (patient or parent report) – St Jude Standard risk received highest dose DEX (significantly lower
sleep efficiency)
• Gender : males
had
more
nocturnal
awakenings
(and
lower sleep efficiency); females napped more
Fatigue
in
Children
with
Cancer(2 separate studies and populations)
• Hospitalized Fatigue score 23 (9-43)
• Home, pre dex Fatigue score 7.5-11.9
• Home, on dex Fatigue score 13-21
• Highest fatigue score possible is 70
• On dexamethasone, fatigue scores are similar to thescores of hospitalized patients

Fatigue in Adolescents with Cancer(2 separate studies and populations)
• Hospitalized Fatigue score 32
• Home, pre dex Fatigue score 23-29
• Home, on dex Fatigue score 32-33
• On dexamethasone, fatigue is the same as whenhospitalized
• Adolescents report higher fatigue scores than do children
Daily Parent
Report
Diary
• 15 item parent report scale
• Reports parents perceptions of child’s sleep and nap
patterns during the previous 24 hours
• Additional items relate to naps, tiredness,
consumption of selected food items and perceived
energy levels
• Items strongly correlated with actigraph findings(r=0.89;p=0.001) (Sadeh, 1994)
• Completed 4 times during 10 day study period

vs.
No
Dex
•Girls did not have significant differences in wake time consistency
weekday versus weekend
•Boys had more consistent wake time on weekdays compared to
weekends
•Boys had more consistent wake times compared to girls
•Dexamethasone (week 2) did not significantly alter wake time
consistency
Association of fatigue with consistent
wake time
• Multiple regression analysis: younger boys
with more consistent wake times had
lower fatigue scores
• May suggest that consistent morning wake times
for the
younger
child
on

Potential Biological Mechanisms of
Sleep Disturbance and of Fatigue
• What are the potential biological mechanisms? – Steroids?
– PK, PGN
– Albumin?
– Cytokines?
– Neuroanatomy or Neurophysiology?
– Neurochemicals?
Potential Biological Mechanisms of
Sleep Disturbance and of Fatigue
• Steroids contribute to altered sleep
disturbances and fatigue
– How?
• Pharmacokinetics
– Exposure to dexamethasone (AUC) increases with age and is higher
in standard care ALL risk compared to low risk groups
– Wake after
sleep
onset
increases
as
AUC
increases
– A decrease in time to attain threshold of 100 nM is significantly
associated with increased sleep efficiency
– No PK association with fatigue
– No association with clearance and sleep or fatigue

http://slidepdf.com/reader/full/from-pain-to-sleep-listening-to-patient-reported-outcomes 24/33
Potential Biological Mechanisms of
Sleep Disturbance and of Fatigue
• Steroids contribute to altered sleep
disturbances and fatigue
– How?
• Pharmacogenomics: SNP genotype and sleep and
fatigue
– AHSG/C>G exon 7 (sleep efficiency)
– CYP11B2/K1733R (sleep duration)
– IL6/IL6_C‐634‐G (sleep duration)
Potential Biological Mechanisms of
Sleep Disturbance and of Fatigue
• Albumin and dexamethasone – Low albumin likely leads to higher and longer exposure to dexamethasone
– Relationship between albumin and fatigue established in adults (direct
relationship not mediated by a steroid)
• Wang et al., 2002, JCO
– albumin and
dexamethasone
associated
during
reinduction
• Yang, et al., 2008, JCO
– No relationship between albumin and dexamethasone PK during
continuation

http://slidepdf.com/reader/full/from-pain-to-sleep-listening-to-patient-reported-outcomes 25/33
Can we improve sleep and fatigue in
children with cancer?
• Increase daytime physical activity
• Modify the hospital sleep environment
• Use relaxation interventions
• Administer pharmacologic interventions
• Consider complimentary therapies
• Implement Educational interventions:
‐ preparing families for likely and fatigue changes
‐ share with families sleep hygiene principles and hours
of sleep needed for their child
Sleep Hygiene
Principles
• consistent bed times and wake times
• making sure that your child receives enough sleep every
day to feel alert and well rested
• naps based on developmental age and stage
• limiting caffeine before bedtime
• child's bedroom at a comfortable temperature
• Child not
going
to
bed
hungry
• child's bed and bedroom are inviting and comfortable
• a regular bedtime ritual to help child prepare for nighttime
sleep

What will happen to me in this study?
You will have to wear the Actigraph all the time you are in the hospital.The Actigraph looks like a watch. It is a little computer.It will tell us how well you sleep.
You will answer questions one time a day.We will ask you about your sleep and how you feel.
