1 Clinical Policy Title: Apnea monitors for infants in-home use Clinical Policy Number: Effective Date: October Initial Review Date: March Most Recent Review Date: April Next Review Date: April 2018 Policy contains: Apnea monitors. Cardiorespiratory monitors. Sudden infant death syndrome. Related policies: None. ABOUT THIS POLICY: Select Health of South Carolina has developed clinical policies to assist with making coverage determinations. Select Health of South Carolina s clinical policies are based on guidelines from established industry sources, such as the Centers for Medicare & Medicaid Serv ices (CMS), state regulatory agencies, the American Medical Association (AMA), medical specialty professional societies, and peer -reviewed professional literature. These clinical policies along with other sources, such as plan benefits and state and federal laws and regulato ry requirements, including any state- or plan-specific definition of medically necessary, and the specific facts of the particular situation are considered by Select Health of South Carolina when making coverage determinations. In the event of conflict between this clinical policy and plan benefits and/or state or federal laws and/or regulatory requirements, the plan benefits and/or state and federal laws and/or regulatory requirements shall control. Select Health of South Carolina s clinical policies are for informational purposes only and not intended as medical advice or to direct treatment. Physicians and other health care providers are solely responsible for the treatment decisions for their patients. Select Health of South Carolina s clinical policies are reflective of evidence-based medicine at the time of review. As medical science evolves, Select Health of South Carolina will update its clinical policies as necessary. Select Health of South Carolina s clinical policies are not guarantees of payment. Coverage policy Select Health of South Carolina considers the use of apnea monitors for infants to be clinically proven and, therefore, medically necessary durable medical equipment (DME) when any of the following criteria are met: Infants who have experienced any apparent life-threatening events (ALTEs) until they remain event-free for six weeks. Infants diagnosed with pertussis with positive cultures, upon discharge from acute care facility. If monitored for pertussis, use of an apnea monitor is considered medically necessary for up to one month post-diagnosis. Infants with tracheostomies or anatomic abnormalities that make them vulnerable to airway compromise.* Infants with neurologic or metabolic disorders affecting respiratory control, including central sleep apnea.* Infants with chronic lung disease (i.e., bronchopulmonary dysplasia), especially those requiring supplemental oxygen, continuous positive airway pressure or mechanical ventilation.* Infants at high risk of recurrent episodes of prolonged apnea with duration greater than 20 seconds, bradycardia (heart rate less than 80 beats per minute) and hypoxemia (oxygen 1

2 saturation below 90 percent) after hospital discharge, until the infant remains event-free for six weeks. Infants with gastroesophageal reflux disease that results in apnea, bradycardia or oxygen desaturation, until the infants remain event-free for six weeks. Infants with apnea accompanied by marked hypotonia; use of an apnea monitor until the infants remain event-free for six weeks. The use of home cardiorespiratory monitoring for infants with apnea of prematurity, defined as sudden cessation of breathing that lasts for at least 20 seconds or at least 10 seconds if accompanied by bradycardia or hypoxemia in infants younger than 37 weeks gestational age. Continued use is considered medically necessary until infants are past post-conceptional age of 43 weeks and are event-free for six weeks. * Except as specified for certain indications noted in this policy, infant apnea monitors are usually considered medically necessary for approximately three months. Continued use of an apnea monitor, during the course specified as medically necessary, is considered medically necessary for the durations noted in this policy, even when infants reach age 12 months. Apnea monitoring for children beyond 12 months old requires physician documentation supporting the continuation of monitoring (e.g., continued alarms, documented apnea, bradycardia, or hemoglobin desaturation). Limitations: All other uses for apnea monitoring for infants are not medically necessary. The use of apnea monitors for remote infrared sensor for the detection of infant sleep apneas is not medically necessary because its effectiveness has not been established. Home cardiorespiratory monitoring is intended in part to alert caregivers to intervene at the time of an event in patients with apnea and is not medically necessary to diagnose sleepdisordered breathing (central or obstructive). Alternative covered services: Increased network physician office visits and evaluation. Background The American Academy of Pediatrics (AAP) defines clinically significant apnea in infants as an unexplained episode of cessation of breathing for 20 seconds or longer, or a shorter respiratory pause associated with bradycardia, cyanosis, pallor, and/or marked hypotonia (AAP 2003). Apnea that occurs in premature infants (gestation under 37 weeks) includes a sudden cessation of breathing for more than 20 seconds or is accompanied by bradycardia or oxygen desaturation (cyanosis). Only a minority of such cases remain unresolved after 37 weeks postmenstrual age, mostly in very premature (gestation under 28 weeks) infants; nearly all of these cases resolve by 43 weeks post- 2

3 conception (AAP 2003). Even among premature infants, apnea and bradycardia are not common; one study of 1403 infants born earlier than 34 weeks gestation found that only 15.8 and 21.5 percent had apnea and bradycardia events after they were otherwise ready for discharge (Lorch 2011). Apnea monitors were introduced in the mid-1960s for the management of apnea of prematurity in hospital settings. Subsequently, cardiorespiratory monitoring became widely used in the care of infants with a variety of acute and chronic disorders. There are three types of infant apnea: Central apnea Both the inspiratory effort and airflow cease simultaneously (absence of chest wall movement and airflow). Obstructive apnea Airflow is absent in the presence of inspiratory efforts (presence of chest wall movement, but no airflow). Mixed apnea Central apnea is preceded or followed by airway obstruction. At one time, experts speculated that sudden infant death syndrome (SIDS) could be caused by sleep apnea. However, apnea is now recognized as not predictive of SIDS, as most apnea cases resolve prior to the usual age of SIDS (45.8 weeks and 52.3 weeks postmenstrual for infants born weeks and all infants). Known practices to reduce SIDS include supine sleep position, firm sleeping surfaces, breastfeeding, roomsharing without bed-sharing, routine immunizations, avoidance of soft bedding and overheating, and elimination of prenatal/postnatal exposure to tobacco smoke. In addition, risk of SIDS in later siblings is known to be extremely low (AAP 2003, Task Force on Sudden Infant Death Syndrome 2011, Eichenwald 2016). Many premature newborns are successfully treated for sleep apnea while in the hospital; caffeine citrate has been shown to be an effective means of treatment, achieving results superior to those from methylxanthamine therapy (Schmidt 2007, Schmidt 2014). The decision of whether or not to discharge an infant after a life-threatening event such as apnea or brachcardia/tachycardia is a difficult one, with limited ability to predict future risk of such an event, according to a systematic review of 37 studies (Tieder 2013). However, if an infant with apnea is otherwise cleared for discharge, the physician recommends the monitor, and the discharge planner, social worker, or case manager coordinate the process. A home apnea monitor is a belt-like device, or involves electrodes. Recently, a remote infrared sensor that does not contact the infant has been developed (Bani Amer 2010). In addition to cardiorespiratory monitors, pulse oximeters with low false-alarm rates can be used to provide information on oxygenation status during events. One study of 37 infants found that 69 percent of 13,228 events lasted fewer than 10 seconds, and that 13 patients needed intervention following alarms, 10 of whom were readmitted to a hospital (Gelinas 2008). Compliance with home sleep apnea monitors has been a concern for practitioners. One review covering 175 families who used 12,862 days of home monitoring documented that families who used telemedicine 3

4 to report results had a higher compliance rate than those using the conventional system, i.e. 70 to 50 percent (Piumelli 2012). While apnea is relatively common among premature infants, the condition is associated only with acute, not chronic, conditions (Fairchild 2016). Searches: Select Health of South Carolina searched PubMed and the databases of: UK National Health Services Centre for Reviews and Dissemination. Agency for Healthcare Research and Quality s National Guideline Clearinghouse and other evidence-based practice centers. The Centers for Medicare & Medicaid Services (CMS). We conducted searches on February Search terms were: home apnea monitor infant and home apnea monitor prematurity. We included: Systematic reviews, which pool results from multiple studies to achieve larger sample sizes and greater precision of effect estimation than in smaller primary studies. Systematic reviews use predetermined transparent methods to minimize bias, effectively treating the review as a scientific endeavor, and are thus rated highest in evidence-grading hierarchies. Guidelines based on systematic reviews. Economic analyses, such as cost-effectiveness, and benefit or utility studies (but not simple cost studies), reporting both costs and outcomes sometimes referred to as efficiency studies which also rank near the top of evidence hierarchies. Findings The 2003 AAP guideline on infant apnea, updated in 2007, recommended home cardiorespiratory monitoring: Should not be used to prevent SIDS. May be warranted for premature infants at high risk for recurring apnea, bradycardia, or hypoxemia after discharge, up to 43 weeks postmenstrual age or after cessation of episodes (whichever is last). Infants dependent on devices such as tracheostomy and continuous positive airway pressure, or who have unstable airways, have rare conditions affecting breathing, or have chronic lung disease. Should only use monitors with an event recorder. Should ensure parents are advised that the technology has not been proven to prevent SIDS. Should ensure promotion by pediatricians of proven practices to decrease SIDS risk (AAP 2003). 4

5 Studies have shown that premature infants who are discharged needed a home monitor for cardiorespiratory functions. One study of 1058 infants found that 96 needed home monitoring, and that 61 of these showed alarms at home. The mean post-conceptional age of stopping alarms was 46 weeks (Naulaers 2007). A 2014 review of 272 discharged infants confirmed that home apnea or pulse oximetry use significantly raised the chance of a readmission within 30 days of discharge (Jurgens 2014). A systematic review of 11 studies (n=2210) assessed the ability of home monitoring to reduce SIDS, but only one study compared results to a control group; the others were cohort studies considered to be level III evidence. The one randomized controlled trial (RCT) calculated the SIDS mortality rate for babies with home monitors to be 5.0 per 1,000, compared to a rates for non-monitored infants ranging from 1.2 to 5.6 per 1,000 (Strehle 2012). An earlier systematic review of 51 studies (n=5901) assessed the ability of portable monitors to diagnose sleep apnea in infants. Results were mixed in terms of low and high likelihood ratios, high or low rates of false negatives/positive, and in terms of whether the evidence level was low or high. Researchers concluded that some studies show increased or decreased chance of diagnosing the disorder via the apnoea/hypopnoea index (Flemons 2003). A study of 1079 infants monitored at home for apnea or bradycardia (over 700,000 hours) found a link between infants with multiple events and less favorable outcomes after one year. Apnea and bradycardia among these infants tended to be preceded by by cardiorespiratory and hemoglobin O 2 saturation changes (Hunt 2008). One assessment of the economic savings of home apnea monitoring for 425 late preterm infants found that home monitoring saved from $62 to $2422 per patient, compared to prolonged inpatient observation (Montenegro 2017).

6 Citation Content, Methods, Recommendations Ability of home apnea monitors to reduce SIDS Systematic review of 11 studies (n=2210) of infants with home apnea monitors. 10 were cohort studies, 1 was randomized controlled trial. 11 deaths documented to be SIDS = event rate of 5.0 deaths per 1000, not different than the rate for non-monitored infants (1.2 to 5.6 per 1000). AAP (2003) Key points: Guideline on use of infant sleep apnea monitoring American Academy of Pediatrics guideline on apnea, SIDS, and home monitoring. Home apnea monitoring should not be used to prevent SIDS. Home apnea monitoring may be warranted for premature infants at high risk for recurring apnea, bradycardia, or hypoxemia after discharge, up to 43 weeks postmenstrual age or after cessation of episodes (whichever is last). Home apnea monitoring should be only for infants dependent on devices such as tracheostomy and continuous positive airway pressure, or who have unstable airways, have rare conditions affecting breathing, or have chronic lung disease.
