V.12.4 Special Report: Unexpected Newborn Complications Update
(NQF #716 “Healthy Term Newborn”)
I. Introduction
This special report is based on the work of the California Maternal Quality Care Collaborative
(CQMCC), the measure steward for National Quality Forum (NQF) measure #716: Healthy
Term Newborn.i As the measure steward, CQMCC developed this measure in response to a need
for a composite measure to identify the most important outcome for families having a birth --
taking home a healthy baby. While there are several measures looking at specific clinical
practices and outcomes in preterm infants, there were no other measures for outcomes in term
babies (who represent 90% of all births).
Initially endorsed by NQF in January, 2011 the Healthy Term Newborn measure identified the
percent of babies without preexisting conditions (no premature infants, multiple gestations, birth
defects, or other fetal conditions) and who are normally grown and were not exposed to maternal
drug use, that did NOT have any severe or moderate complications. Feedback to the measure
developers has initiated an update to the measure to reverse the numerator and measure
“Unexpected Newborn Complications”, those newborns without preexisting complications who
do have a severe or moderate morbidity.
The source of the data for this measure is administrative claims data, using a combination of
ICD-9 diagnosis and procedure codes and neonatal length of stay (LOS) to categorize
complications. This measure is a key balance to other NQF endorsed measures that examine
obstetric care in this population such as cesarean section and episiotomy rates. Most families
would value having a low chance of unexpected newborn complications and low to medium rates
of these obstetric procedures.
Denominator: Babies without preexisting conditions are identified using patient discharge data.
The denominator (Flow chart: Figures 1 & 2) is comprised of singleton live born babies who are
at least 37.0 weeks of gestation, ≥ 2500 grams in birth weight (normally grown), do not have any
congenital malformations or fetal conditions, and are not exposed to maternal drug use or to
selected maternal conditions (see Flow Chart and Appendices 1 and 2 for a list of ICD-9 codes
and descriptions). This is a group who are expected to do well and go home routinely with the
mother.
Numerator: The numerator (Flow chart: Figures 3 & 4) is divided into two categories: severe
complications and moderate complications. Severe complications (Appendix 3) include
neonatal death, transfer to another hospital for higher level of care, extremely low Apgar score ≤
3 at either 5 or 10 minutes of life), severe birth injuries such as intracranial hemorrhage or nerve
injury, neurologic damage, severe respiratory, neurologic or infectious complications. Parents of
such babies may often worry about short or long term infant outcomes. Moderate complications
(Appendix 4) include diagnoses or procedures that raise concern but at a lower level than the list
for severe (e.g. use of CPAP or bone fracture). Most require an infant LOS that exceeds that of
Page 2
the mother, validating that these are indeed significant complications. Examples include less
severe respiratory complications (e.g. transient tachypnea of the newborn), or infections with a
long LOS but not sepsis. As a “safety net” to capture cases who were under-coded, the
numerator also includes cases from these seemingly normal infants who has a LOS >5 days with
neither any form of jaundice nor a social reason for staying in the hospital (e.g. family disruption
or adoption; Appendix 5).
Measure Calculation: In this analysis, the measure is reported as the percent of Total
Unexpected Newborn Complications (per 100 births) subdivided into serious and moderate
complications (further details are in the Flow Chart and Appendices).
II. Description of Tables and Graphs
The V12.4 Special Report: Unexpected Newborn Complications (UNC) Update (NQF # 716
“Healthy Term Newborn”) is designed to provide you with an understanding of the data and
analysis of unexpected severe and moderate newborn complications. The tables in this analysis
display data for your hospital compared to NPIC/QAS subgroup and database averages. The
report includes data for discharge date range 1/1/12 – 12/31/12. Medical record numbers for
the cases contributing to your hospital’s rates are available by emailing [email protected].
We are happy to answer any questions you may have regarding this report.
Table 1: Overview displays UNC measure population information and rates. (See Flow Chart
and Appendices for measure specification details).
Section A: Inborns shows the count of total inborns for the time period and the percent of total
inborns with valid APGAR 5 information. Apgar score at five minutes is included in the UNC
rate calculations (Total and Severe). If your hospital did not submit valid APGAR 5 information
these rates may be understated. This section also displays the number of inborns that were
excluded from the measure population because they did not meet the initial criteria for inclusion
(preterm inborns or multiple gestations are excluded).
Section B: Denominator begins with the count of inborns in the UNC “starting denominator”
The starting denominator includes all inborn singletons with birthweight ≥ 2500 grams and
gestational age ≥ 37 weeks (birthweight and gestational age were determined using the numeric
and coded information provided in the NPIC/QAS data submission from each hospital). The next
display is the total inborns excluded due to “preexisting” complications (congenital
malformations and genetic disorders, other specified fetal and maternal conditions, and maternal
drug use) shown as a count and as a percent of the starting denominator. The number of
remaining inborns in the measure population (without preexisting complications) is then
displayed as the UNC Final Denominator.
Section C: Unexpected Newborn Complication Rates displays the Total UNC Numerator (the
number of inborns identified with severe or moderate complications in the measure population)
and the Total UNC Rate. This information is then divided into two sub measures, Severe
(includes just those inborns identified with severe complications) and Moderate (inborns with
moderate complications only).
Page 3
Graph 1: Comparative Unexpected Newborn Complication Rates is a bar graph showing
your hospital’s Total UNC Rate with a 95% confidence interval compared to the other hospitals
in your subgroup. The bar displays the percent of severe and moderate complications within the
Total UNC Rate. The average Total UNC Rate for the subgroup and the database are displayed
by two horizontal lines.
Graph 2: Comparative Unexpected Newborn Complication Rates Summary by Subgroup
displays the average Total UNC Rate with the percent of severe and moderate complications for
each NPIC/QAS subgroup and the entire database.
Table 2: Severe Complications by Category provides information for the inborns in the UNC
numerator identified with severe complications.
Section A: Overview shows case counts for the UNC Final Denominator and the Severe UNC
numerator (inborns in the measure population with severe complications) and then displays the
Severe UNC Rate. This section also displays the percent of inborns with severe complications
admitted to a special care nursery (defined as inborn discharges with neonatal intensive care
(NICU) or neonatal intermediate care (NINT) accommodation days or charges on the data
submission).
Section B: Numerator Inclusions: Severe Complications by mutually exclusive categories
displays the case counts for each of the five categories of severe complications included in the
UNC numerator( as described in Figure 3 of the Flow Chart); died, transferred out to a higher
level of care (within 1 day of birth), Apgar score ≤ 3 at five minutes, severe ICD-9 coding
(includes specific diagnosis and procedure codes for birth trauma, hypoxia/asphyxia, shock and
resuscitation, respiratory complications, infection, and neurological complications) and inborns
coded with Septicemia (dx 771.81) with a length of stay greater than four days. The percent of
total severe complications is also displayed for each category. The shaded area shows the
distribution of cases within the code groups of the severe ICD-9 coding category (see
Appendices, Numerator Specifications for ICD -9 code lists). Cases with multiple codes may be
included in more than one of these groups but are only counted once in the numerator.
Table 3: Moderate Complications by Category provides information for the inborns in the
UNC numerator identified with moderate complications.
Section A: Overview shows case counts for the UNC Final Denominator and the Moderate
UNC numerator (inborns in the measure population with moderate complications) and then
displays the Moderate UNC Rate. This section also displays the percent of inborns with
moderate complications admitted to a special care nursery (defined as inborn discharges with
neonatal intensive care (NICU) or neonatal intermediate care (NINT) accommodation days or
charges on the data submission).
Section B: Numerator Inclusions: Moderate Complications by mutually exclusive
categories displays the case counts for each of the three categories of moderate complications
included in the UNC numerator (as described in Figure 4 of the Flow Chart); moderate
complications without a length of stay (LOS) requirement to validate severity, moderate
complications with specific LOS requirements (LOS > 2 days for inborns delivered vaginally;
LOS > 4 days for inborns delivered by c- section; LOS ≤ 4 days for inborns coded with
Page 4
septicemia) and inborns with LOS > 5 days (inborns with specific codes for neonatal jaundice or
social indications for prolonged hospitalization are excluded). The percent of total moderate
complications is also displayed for each category. The shaded areas show the distribution of
cases within the diagnosis and procedure code groups of the Moderate Complication (with or
without LOS requirement) categories. (see Appendices, Numerator Specifications for ICD-9
code lists). Cases with multiple codes may be included in more than one group but are only
counted once in the numerator.
