The systematic review will answer the
following questions. This information is
provided as background. AHRQ is not
requesting that the public provide
answers to these questions.
Contextual and Key Questions (KQ)
Contextual Questions
CQ 1: What measures related to
apneas and hypopneas (e.g., apnea
indices, hypopnea indices, and apneahypopnea indices with various
measurements) or other measures (e.g.,
time spent with oxygen saturation
below 90% or other cutoffs,
electrophysiologic signal analysis
metrics such as time and frequency
domain analyses of heart beats) are used
in contemporary research and clinical
settings? How have standard definitions
of these measures changed over time
and what is the explanation for such
changes?
CQ 2: What are commonly used sleep
questionnaires and how have they been
validated?
CQ 3: What treatment modalities for
OSA are currently being marketed in the
U.S.? What OSA treatments
(experimental or approved) are
currently being investigated in ongoing
trials for patients as an alternative to
CPAP?
CQ 4: What are the variable features
of marketed CPAP devices?
CQ 5: What are the patient-centered
health outcome goals and symptom
relief goals of CPAP devices?
Key Questions
KQ 1: What is the efficacy,
effectiveness, comparative effectiveness,
and harms of CPAP devices to improve
clinically significant outcomes?
KQ 1a: How are respiratory
disturbance events (apnea, hypopnea,
E:\FR\FM\14JYN1.SGM
14JYN1
Federal Register / Vol. 85, No. 135 / Tuesday, July 14, 2020 / Notices
arousal) defined in each study? What
are the diagnostic criteria for OSA (or
criteria to treat with CPAP) in each
study? How do the diagnostic criteria
relate to time of AASM criteria? Do
treatment effects of CPAP differ by the
specific diagnostic criteria used within
or across studies?
KQ 1b: What is the within-study
concordance in CPAP trials among
apnea and hypopnea indices (e.g., AHI),
sleep questionnaires (e.g., Epworth
Sleepiness Scale), and clinically
significant outcomes?*
KQ 1c: Do the clinical effects or harms
of specific CPAP devices differ by
patient subgroups, duration of followup,
or particular CPAP features?
KQ 1d: Summarize the
methodological issues in the existing
studies.
KQ 2: What is the evidence that apnea
and hypopnea-based measures of sleepdisordered breathing (e.g., apneic
indices, hypopnea indices, and apneahypopnea indices) used in current
practice and research are valid surrogate
or intermediate measures for clinically
significant outcomes?
KQ 2a: Summarize the
methodological issues in the existing
studies. What is the ideal study design
for establishing the validity of a
surrogate or intermediate measure?
* Note that the association between
changes in apnea and hypopnea indices
and clinical outcomes across a broader
set of studies is primarily addressed in
KQ 2.

SUPPLEMENTARY INFORMATION:
Proposed Project
Clinical Decision Support (CDS) for
Chronic Pain Management
Prescription opioid pain medication
overuse, misuse, and abuse have been a
significant contributing factor in the
opioid epidemic. The goal of this project
is to develop, implement, disseminate,
and evaluate clinical decision support
(CDS) tools for both patients and
clinicians in the management of chronic
pain. The CDS tools are intended to be
interoperable and publicly-shareable,
and will be designed to meet the needs
of patients and clinicians through both
patient-facing and clinician-facing
channels and formats.
The development and deployment of
CDS tools designed to optimize opioid
dose reduction is intended to support
primary care physicians who are not
pain-management specialists as they
care for patients who are at high risk of
harm from opioids. This goal will be
achieved through the design,
development, implementation, and
evaluation of a clinician-facing CDS tool
for chronic pain management that
optimize presentation of patient data
and evidence-based guidelines to
support opioid tapering. The clinicianfacing CDS tool will help non-pain
specialists detect patients at high risk of
harm from opioids, provide
personalized evidence-based guidelines
to support opioid tapering, optimize the
presentation of patient data, and reduce
unnecessary variation in clinical
practice.
The clinician-facing CDS tool will
also assist non-pain specialists in
determining if an opioid taper is
necessary for a specific patient, aid in

valid surrogate or intermediate measures for clinically significant
outcomes?
KQ 2a: Summarize the methodological issues in the existing studies.
What is the ideal study design for establishing the validity of a
surrogate or intermediate measure?
* Note that the association between changes in apnea and hypopnea
indices and clinical outcomes across a broader set of studies is
primarily addressed in KQ 2.

adherence (i.e., not an intervention of CPAP, per se)
Exclude evaluations of accessories only (e.g., nasal cannulas,
head straps, humidifiers)
Exclude evaluation of CPAP titration methods, per se,
including specific parameters or modes (e.g., starting pressures)
Exclude evaluations of other features meant to improve comfort
or adherence
Exclude other non-CPAP interventions (e.g., different times of
monitoring, scoring), including noninvasive ventilation
Comparators
No CPAP
Non-CPAP active interventions for OSA (e.g., mandibular
advancement device)
[cir] Exclude bariatric surgery (as a comparator treatment)
[cir] Exclude surgical OSA procedure (as a comparator treatment)
Other CPAP modality or protocol (e.g., autoCPAP vs. bilevel
CPAP)
[[Page 42404]]
Exclude comparisons with different accessories, titration methods,
features to improve comfort or adherence, other non-CPAP interventions
(e.g., different times of monitoring, scoring), including noninvasive
Outcomes
As listed above, for both KQs
Sleep and breathing measures (e.g., AHI) and validated sleep
questionnaires (e.g., Epworth Sleepiness Scale) (only for the purpose
of addressing KQ 1b, not as outcomes of interest)
Adverse events related to CPAP use
Mediators of treatment effect (e.g., subgroup analyses; see note
above about mediators)
As listed above, for both KQs
New or prior OSA diagnosis
Treatment na[iuml]ve versus failed prior treatment
First versus second or more use of CPAP
Treatment (CPAP) compliance
Treatment (CPAP) discontinuation
Design
Randomized controlled trials (RCT)
[cir] Consider whether study met power calculation for the
outcome(s) of interest (including adverse events)
Nonrandomized comparative studies (NRCS)
[cir] Restrict to studies that use modeling or other analytic
methods to minimize confounding bias (due to inherent differences
between people who receive one or the other intervention)
[cir] Exclude case-control design
[cir] Exclude ``pre-post'' design (comparison of before and after
CPAP treatment in a single group of participants)
Longitudinal
[cir] Exclude cross-sectional
Additional Eligibility Criteria Specific to KQ 2
For KQ 2, we will include studies that measure a change in the
intermediate/surrogate measure (e.g., AHI) over a period of time and
report on outcomes of interest. We will include studies that provide
formal evaluation of validity of the intermediate/surrogate measure for
the clinical outcome and other studies that report sufficient data to
analyze a potential association between the change in the measure and
the clinical outcome.
Population
Adults
[cir] Do not require a diagnosis of OSA (for evaluations of
associations of measures)
[cir] Exclude populations as described under ``Eligibility Criteria
relevant to Both KQs''
Intermediate/Surrogate measures (variables of interest evaluated
regarding their association with clinical outcomes)
Sleep and breathing measures
[cir] Indices based on apneas or hypopneas (e.g., AHI, RDI) or
other respiratory events such as RERAs, oxygen desaturations
Exclude evaluations of isolated neurophysiologic parameters of
sleep (e.g., respiratory effort, heart rate, air flow, pulse oximetry
alone) and cardiac electrophysiology indices (e.g., heart rate
variability)
Outcomes
As listed above, for both KQs
Each study must report both one or more intermediate/surrogate
measures (i.e., sleep and breathing measures) and one or more outcomes
of interest
Additional mediators of association (e.g., analyzed by subgroup
analyses)
As listed above, for both KQs
Definition of sleep and breathing measure
Study Design
Longitudinal studies informing on person-level associations of
sleep and breathing measure(s) with outcome(s)
[cir] Patient-level association between change in measure and
change or incident outcome (i.e., evaluation of association reported
within study)
[cir] Exclude cross-sectional studies
Comparative or noncomparative (single group) studies
N >= 30 analyzed for a given association between intermediate/
surrogate measure and outcome
