A Tale of Two “Terrible” Sleepers

Similar Clinical Complaints• Patient #1

• 5 year old girl with frequent night wakings• Falls asleep independently in 10 minutes• 4/7 nights wakes and is up for 2-3 hours• Will go tell parents she’s awake, but then goes

back to room to read

• Patient #2• 2 year old girl with disrupted sleep pattern• Falls asleep independently in 10-30 min• Minimum of 1 waking/night, lasting 3-4 hours• Does not cry for parents, but they hear her

laughing and playing

Detailed Teaching/Instructions

• Care and maintenance

• Care and maintenance • Importance of sleep diary

• Care and maintenance • Importance of sleep diary• Show an example of an actigram

• Care and maintenance • Importance of sleep diary• Show an example of an actigram• Sign receipt

Follow-Up Visit• 60 minute appointment

• Download actigraph• Review sleep diary for anomalies • Set sleep intervals on scoring program• Create summary variables• Review data with patient/family• Print actigram for patient to take home

addition to clinic visit• Category I CPT code (95803)

• Actigraphy, testing, recording, analysis, interpretation and report (minimum of 72-hours to 14 consecutive days of recording, requires the patient to wear a home monitor for 24-hours a day for 3 to 14 days)

Actigraphy Billing - NJH• Standard charges: tech fee $155, pro fee

$95• Medicare allowable: tech fee $54.12, pro

fee $44.05• Medicaid allowable global fee of $49.96• All commercial payers consider actigraphy

experimental• Patients can self-pay global fee of $98• Patients can sign Advance Beneficiary Notice

(ABN) where if insurance denies, patient is responsible for standard charges

Clinical Indications and Pediatric Scoring Considerations

Strongly recommended:• MSLT preceded by >7 days of

actigraphy with sleep log to establish if results biased by insufficient sleep, shift work, or circadian rhythm sleep disorder

Diagnostic Criteria D:The presence of > 1 of the following:1. MSLT shows mean SOL < 8 minutes2. Total 24-hour sleep time is ≥ 660

minutes (11 hrs) by 24-hour PSG or by wrist actigraphy in association with a sleep log (averaged over at least seven days with unrestricted sleep)

Individual Day Analysis

Diagnostic Criteria B:The patient’s sleep time, established by personal or collateral history, sleep logs, or actigraphy is usually shorter than expected for age

Notes: If there is doubt about the accuracy of personal history or sleep logs, then actigraphy should be performed,

Sleep Offset 7:49 a.m.

15 Year Old Female

Diagnostic Criteria D:Sleep log and, whenever possible, actigraphy monitoring for at least 7 days (preferably 14 days) demonstrate a delay in the timing of the habitual sleep period. Both work/school days and free days must be included within this monitoring

Circadian Rhythm Sleep Disorders and Actigraphy

Leg actigraphy has been validated against PSG for the measurement of PLMS and provides a methodology to assess PLMS in large populations, as well as night to night variability

Periodic Limb Movement and Actigraphy

Restless Sleepers

Similar Clinical Complaints• Patient #1

• 10 year old male who is difficult to wake• Restless sleeper, kicks in sleep, no one

wants to share a bed

• Patient #2• 17 year old female who feels unrefreshed

upon waking• Restless sleeper, kicks in sleep, no one

wants to share a bed

Pre-Post Treatment

• 7 year old boy• Difficulties falling asleep and

multiple night wakings• Daytime fatigue and behavior

problems• Restless sleeper• Low serum ferritin (20 ng/mL)

• How much activity is normal?• What if bedtime and wake time are not

clear or consistent?

• How much activity is normal?• What if bedtime and wake time are not

clear or consistent?• What if there isn’t a diary?

• In peds, parent often reports on child’s sleep patterns

• Patients not always good historians/ diary keepers

• Sleep patterns can significantly differ on weekdays, weekends, and holidays

• Watches can get lost/damaged• Placement of device/will child tolerate

Your Turn

Why Are These Wakings Circled?

What Was the Referral Question?

Summary• Actigraphy useful clinical tool in pediatrics

• Provides additional information about sleep-wake patterns

• Should be used prior to MSLT to ensure adequate sleep duration

• Can monitor treatment adherence/outcomes

• Important to have sleep diary/event markers and to get the watch back!
