ABSTRACT. Home apnea/bradycardia monitoring is fre-quently used in the management of infants at increased risk for sudden infant death syndrome (SIDS). However, some infants have died despite evaluation by infant apnea programs, and the benefits of home monitoring remain unproven. To determine the SIDS rate and risk factors of infants evaluated by infant apnea programs, 31 apnea programs and ten home monitor vendors in California were surveyed. Eleven (35%) of the apnea programs and four (40%) of the vendors responded. Information was obtained on 26 infants who died. Thirteen (50%) deaths were due to SIDS. Abnormal sleep studies did not predict death. Fifteen infants died despite a recommendation for home monitoring. Seven deaths occurred in association with technical errors or noncompliance with monitoring. Four deaths were due to nonaccidental trauma. The ap-nea programs evaluated 3,406 infants during a 5-year period; 1,841 had monitoring recommended. Term in-fants with apnea, subsequent siblings of SIDS victims, and infants evaluated at referral centers were more likely to have monitoring recommended than premature infants with apnea or infants evaluated at nonreferral centers (P < .0001). Infants who had monitoring recommended were at equal risk of dying of SIDS as those who did not.

the ages of 1 month and 1 year.’5 Because the

causes of SIDS are unknown and the SIDS victim

cannot be accurately identified prior to death, SIDS

cannot be prevented.6 However, several groups of

infants have been described as being at increased

risk for SIDS. These groups include term infants

with unexplained apnea,7’1 premature infants,’2”3

and subsequent siblings of SIDS victims.’4”5

Recently, evaluations of respiratory control,

res-piratory stimulants, and home apnea/bradycardia

monitoring have been used in the management of

these infants in an attempt to reduce their risk of

SIDS.8” These techniques are based on the theory

that prolonged apnea may culminate in a SIDS

death.’6”7 Management has increasingly consisted

of home monitoring for apnea and bradycardia.

Caretakers are trained to respond to monitor

alarms with specific interventions aimed at reviving

the baby. The impact of these strategies on

pre-venting deaths in these high-risk groups is

un-known, and home apnea/bradycardia monitoring,

although widely practiced, remains controversial.6

Some infants evaluated and managed by infant

apnea programs offering home apnea/bradycardia

monitoring have died despite these efforts.’#{176}

Pre-vious reports have stressed technical difficulties as

the reason for the failure to prevent these deaths.8

It is possible that advances in monitoring

tech-niques have resulted in fewer deaths in recent years.

However, some infants have died when monitoring

performed correctly.9”#{176}”8 This study attempts to

identify the characteristics of those infants who

(2)

It is hoped that this will increase our understanding

of the outcome of infants at highest risk for SIDS

and possibly identify risk factors.

METHODS

A questionnaire was sent to 31 programs in

Cal-ifornia identified as caring for large numbers of

infants who are at increased risk of dying of SIDS.

Six of the programs (19%) were large

university-affiliated referral centers. Nine (29%) were

hospi-tal-based nonreferral centers mainly caring for

pa-tients presenting to their hospital. The remaining

16 (52%) were smaller private practice infant apnea

programs affiliated with community hospitals,

mostly caring for less than 100 infants in the past

4 years.

The questionnaire contained general questions

regarding the date the program began and the

num-ber of patients evaluated as term infants with

ap-nea, as premature infants with apnea, and as

sub-sequent siblings of SIDS victims from 1980 to 1984.

Term infants with apnea were defined as those with

a convincing history of an apparent life-threatening

event characterized by a color change (cyanosis or

pallor), tone change (limpness), and apnea that

required resuscitation or vigorous stimulation.7

After a diagnostic evaluation, these infants were

categorized as having either unexplained apnea, if

no cause was found, or apnea with a treatable

etiology. It is the practice of all infant apnea

pro-grams in the survey to recommend home

monitor-ing for term infants with unexplained apnea.

Sub-sequent siblings of SIDS victims were defined as

infants with one or both parents having lost a

previous child to SIDS. The diagnosis of SIDS in

the previous child was made on the basis of autopsy

results. Apnea ofprematurity was defined as infants

presenting with apnea at less than 37 weeks’

ges-tational age. The number of patients from each

group for whom monitoring was recommended and

criteria for monitoring and discontinuing

monitor-ing were requested.

The questionnaire also asked for specific

infor-mation about each infant evaluated by the program

between 1980 and 1984 who had subsequently died.

This included the diagnostic category, diagnostic

evaluation, therapy prescribed, parental

compli-ance, circumstances surrounding the death, and

cause of death. Similar questionnaires were sent to

ten vendors of home apnea/bradycardia monitors

in California in order to increase the sample size

when examining characteristics of infants who died.

The overall mortality rate of patients evaluated

by the infant apnea programs and the mortality

rate for SIDS only were calculated and compared

between those exposed and those not exposed to

each risk factor. In this study, the factors evaluated

included the presence of apnea in term infants,

being a sibling of a SIDS victim, apnea of

prema-turity, a recommendation for monitoring, being

cared for in a referral center, and the use of

the-ophylline for infants with apnea or prematurity.

The 95% confidence limits for the death rates

were obtained by assuming that the relatively rare

occurrence of deaths follows a Poisson

distribu-tion.’9 Although the statistical significance of the

difference of two death rates can be determined

when the 95% confidence intervals do not overlap,

it is possible that there is a significant difference

between the means when two 95% confidence limits

overlap.20 Therefore, the probability of each

ob-served number of deaths and its extreme cases was

derived based on the Poisson distribution with

ex-pected number of deaths when no difference

be-tween the groups is assumed.21 This allowed the

determination of the significance of the relative

risk for each risk factor.

RESULTS

Eleven of 31 (30%) infant apnea programs and

four of ten (40%) monitor vendors responded to the

questionnaire. The referral centers had the highest

response rate, followed by hospital-based

nonrefer-ral centers and private practice programs, as shown

in Table 1.

One infant apnea program and all of the monitor

vendors who submitted their results were unable to

provide information regarding total numbers of

in-fants evaluated in each diagnostic category. Their

reports were, therefore, not included in the evalu-ation of the risk factors but were used in the general

descriptions of the infants who died. Data on deaths

that had been monitored for reasons unrelated to

apnea or the risk of SIDS, such as infants with

chronic fatal underlying conditions, were excluded

from analysis.

of the

premature infants who died was 30 ± 3 weeks. The

mean postconceptional age (±SD) at death was 42

56 weeks’ postconceptional age (4 months corrected

age).

Of the

26 infants

who

died,

15 had

monitoring

recommended at the time of death. Seven of these

had a report of noncompliance or a technical error

in monitoring at the time of death. Two families

refused or discontinued monitoring against the

phy-sician’s advice. Three infants were off the monitor

at the time of death: one during a car trip, one

following a bath, and one napping in the parents

bed. One infant’s monitor was nonfunctional, and

the child was unmonitored during the night of

death. In one instance, the caretakers slept through the monitor alarm.

Twenby-one infants who died (81%) were

evalu-ated by sleep studies, either pneumograms or

poly-somnography.2225 Ten had at least one abnormal

study and six of these died of SIDS. Eleven infants

who died had no abnormal test results and five of

these died of SIDS. The cross-tabulation of the

results of sleep studies and types of deaths is shown

in Table 4.

General

Characteristics

of Infant Apnea

Programs

The ten infant apnea programs that completed

the questionnaire fully have evaluated 3,406 infants

for either term apnea, apnea of prematurity, or a

positive family history of SIDS. Of the infants

evaluated, 1,841 (54%) were placed on home apnea/

greater percentages of term infants with apnea and

ap-nea

(P < .0001). When monitoring was

recom-mended, all programs used combined

apnea/brad-ycardia monitors. Referral centers recommended

monitoring for a significantly higher proportion of

infants (P < .0001). Sleep studies, either

pneumo-grams (overnight recordings of ECG and

respira-tory rate) or polysomnography were usually

per-formed in all three groups of infants. An abnormal

study was rarely required to make the diagnosis or

to institute home monitoring in either the term

apnea

or the

subsequent

sibling

group.

Preterm

infants were frequently required to have an

abnor-mal sleep study before home monitoring was

rec-ommended. About half of the programs used

ophylline or caffeine in the management of

pre-mature infants with apnea. About one third of

programs used theophylline for term infants with

apnea. Rare use of theophylline was reported by

two programs for subsequent siblings of SIDS

vic-tims.

The criterion

for discontinuing

home

monitoring

for all programs was 2 to 3 months without an

apparent life-threatening event for all three

diag-nostic categories. Other criteria frequently used by

most programs were normal sleep studies and

Asymptomatic siblings of SIDS victims were

mon-itored until they passed the age of death of the

previous SIDS victim.

Relative

Risks of Mortality

There were 17 deaths reported by apnea

pro-grams among the 3,406 infants evaluated. Eleven

of these were related to SIDS. A comparison of the

overall mortality rates per 1,000 infants evaluated

for each risk factor, comparing the group at risk

with the group not at risk, is shown in Fig. 1. Similar

data for deaths due to SIDS only are shown in Fig.

2.

There was no significant difference in the overall

mortality between the infants exposed to a risk and

those not exposed for any risk factor. The overall

death rate of those who had monitoring

recom-mended was essentially the same as those who did

not. To assess any bias introduced by the higher

percentage

of referral

centers

responding

to the

survey, evaluation of an infant by a referral center

was considered as a separate risk factor. There was

no significant

difference

between

the overall

death

rate from infants evaluated at referral centers and

mortality ofpremature infants from programs using

theophylline frequently was compared with the

mortality of those from programs that rarely or

never used theophylline. The results are shown in

Table 6. No significant differences were found

be-tween the two groups for total deaths and for SIDS

only.

Among the 1,841 infants who had monitoring

recommended, seven subsequently died of SIDS. Of

these deaths, five were associated with technical errors or noncompliance with monitoring

tech-nique. One infant died of SIDS despite proper

tech-nique and parental response. For one infant, the

record of the monitoring technique at the time of

death was unavailable. There were three other

in-fants who died suddenly in the monitored group;

one died of nonaccidental trauma, one did not have

an autopsy, and one was found to have

subarach-noid hemorrhage at autopsy. There were no

moni-toring errors reported for the latter two infants.

There were seven infants who died among the

1,565 infants who did not have a recommendation

for monitoring at the time of death. Four of these

were deaths due to SIDS, two died of nonaccidental

trauma, and for one no autopsy report was

avail-able. Six of the seven deaths among the

unmoni-tored group were infants with a history of

prema-turity.

DISCUSSION

The findings of this study might have been

af-fected by several factors. This is a retrospective

study, combining reports of different programs that

might have different ways of recording information.

All programs attempted to maintain contact with

patients until the infant was at least 1 year of age.

However, it is likely that there were some infants

lost to follow-up. Therefore, it is possible that some

deaths were unreported. Monitored infants may

have had more close follow-up, and reports may be

more complete for this group. Apnea programs that

have had infant deaths might have responded to

the survey differently. Although every apnea

pro-gram known to us in California was surveyed,

met-ropolitan areas are more heavily represented than

rural areas.

The findings of this study demonstrate that

eval-uation by an infant apnea program does not

elimi-nate the risk of SIDS or death from other causes in

all high-risk infants. Those infants who had

moni-toring recommended were at equal risk of dying of

SIDS as those who did not. However, these results

need not necessarily be interpreted to mean that

home monitoring is ineffective. Infants who had

monitoring recommended are those considered to

be at highest risk for SIDS. Therefore, equivalent

SIDS death rates may be the result of an improved

outlook in the monitored infants.

Previous reports have estimated the risk of dying

of SIDS for infants with unexplained apnea, apnea

of prematurity, and as subsequent siblings of SIDS

victims to be five to ten times that of the general

population.7’5 The average SIDS death rate for the

general population in California was 1.6 per 1,000

live births during 4 of the 5 years of the study (1980 to 1983 inclusive; 1984 statistics were unavailable).

Our results show a SIDS death rate for all of the

infants who had monitoring recommended to be 3.8

per 1,000 infants evaluated. This rate is

signifi-cantly higher than the expected 1.6 per 1,000 death

rate for the general populaton in California at P <

.033 based on the Poisson distribution. Although

this is significantly higher than the risk of the

general population, it is much less than the five to

ten times increased risk previously reported. This

suggests that home monitoring may have prevented

SIDS in some high-risk infants.

Sleep studies such as pneumograms or

polysom-nography are used frequently in the evaluation of

shown in our results, sleep studies do not accurately

predict clinical outcome.7’8 Eleven infants who died

of SIDS were studied prior to death. Five of these

infants never had abnormal sleep study findings

prior to death. Because normal sleep study results

do not rule out the possibility of subsequent death

or SIDS, decisions regarding treatment of infants

at increased risk for SIDS should not be made on

the basis of sleep study results alone.

Monitoring errors or noncompliance with

moni-toring technique were commonly reported in

asso-ciation with infant deaths. Seven of the 11 infants

who died of SIDS reported by the apnea programs

had home monitoring recommended at the time of

death. For one infant, the monitoring technique at

the time of death is unknown. For five of the

remaining six infants, there was a technical error

in monitoring at the time of death. If the five

infants whose deaths were associated with a

moni-toring error are considered to have been

unmoni-tored and a new SIDS death rate is calculated, the

difference in SIDS death rate for monitored v

un-monitored becomes significant as shown in Table

7. This is based on the assumption that infants who

were monitored and did not die had no errors in

technique. Also, it is possible that these five infants

would have died despite perfect monitoring

tech-nique. Further studies are needed to settle these

issues; however, at this time it seems prudent to stress compulsive monitoring technique to the

care-takers of infants on home monitors.

Five of the 26 infants who died did so despite

apparently appropriate monitoring technique and

parental response. Two were SIDS deaths, one was

due to a subarachnoid hemorrhage, and, for two, no

autopsy reports are available. These data

demon-strate that home monitoring, even without

appar-ent errors, will not prevent all SIDS deaths.

Oren et al’8 have reported that infants with

re-peat episodes of unexplained sleep apnea requiring

mouth to mouth resuscitation represent an

ex-tremely high-risk group for SIDS (28% SIDS

fatal-ity rate). There were three infants with a similar

history who died of SIDS in our study. Further

evaluation of this extremely high-risk group may

increase our understanding of SIDS and, in time,

decrease the mortality.

Nonaccidental trauma was the cause of death in

four of the 26 deaths reported. Stress within a

family may increase the risk of child abuse. It is

possible that caring for infants at increased risk for

SIDS may increase stress in the family.

Psychoso-cial support for the parents of infants at increased

risk for SIDS should be an integral part of their

care.

$3.2 MILLION SUIT BY

PARENTS

OF SEPTUPLETS

Six months ago, when Samuel and Patricia Frustaci became the parents of

America’s first septuplets, the ebullient father said: “It’s a neat experience.

Family life is great.” But now, with four of the children dead and the survivors

and their mother facing continuing medical problems, the family has sued the

doctor and the clinic who helped make the births possible.

Faced with mounting medical bills, the Frustacis, charging malpractice, are

seeking $3.2 million in damages for the deaths of four of the infants and for

injuries to the three others.

That the three infants survived is a tribute, their doctors say, to neonatal

technology that was unheard of a decade ago. By all accounts there had never

been any survivors in a set of septuplets anywhere in the world.

All three infants are now home with their parents. An alarm is set off if

breathing stops. Then it is usually up to Mrs. Frustaci, who is tied to her infants

through a remote control device attached to the monitors, to shout at the infant

in trouble. Then the infant remembers to breathe.

The infants also have heart and eye problems. One has a hernia. Another can

be fed only while lying on his stomach. Mrs. Frustaci says she now suffers from

a kidney disorder, among other problems.

Mr. Frustaci’s insurance covers each of the children for up to $1 million for

life, but the infants’ problems are expected to continue, and their medical bills

may soon reach $2 million.
