National Data Review: Five Sources That Could Describe Childhood Asthma on One County's East Side, Judged by the Finest Unit Each Can Resolve, Whether It Counts or Models, and Who Its Frame Leaves Out
The Question the Sources Must Serve
The local profile found that children on our county's east side visit the emergency department for asthma about 6.6 times as often as children elsewhere in the county. Two questions follow that local discharge data cannot answer. Is the high visit rate driven by more children having asthma, or by children with asthma having worse control or poorer access to routine care? And how does the east side compare nationally? This review examines five national data sources against those questions, using three tests: the finest geographic unit the source can resolve, whether its local figures are counted or modeled, and who its sampling frame leaves out.
Source 1: State Emergency Department Databases
What it is. The Healthcare Cost and Utilization Project, a federal program housed at the Agency for Healthcare Research and Quality, assembles state emergency department databases from participating states, with a record for each visit (Agency for Healthcare Research and Quality, n.d.).
Finest unit. The records include patient residence information such as ZIP code, and in some states finer detail, subject to each state's release rules.
Counted or modeled. Counted. Each visit is a record.
Who is left out. Children who have asthma but do not visit an emergency department, and visits in states that do not participate or do not release data.
Verdict. This is the national counterpart of our local source and the right way to compare our visit rate with other places on the same definition. It cannot tell us how many children have asthma, only how many visits occurred.
Source 2: PLACES Small-Area Estimates
What it is. A Centers for Disease Control and Prevention project that publishes estimates of health measures, including current asthma, at the county, city, census tract and ZIP code tabulation area levels (Centers for Disease Control and Prevention, n.d.).
Finest unit. Census tract.
Counted or modeled. Modeled. The estimates are produced from survey responses using multilevel regression and poststratification, which predicts prevalence in small areas from the characteristics of their populations and from patterns in similar areas (Zhang et al., 2014).
Who is left out. The estimates describe adults. There is no tract-level estimate of childhood asthma.
Verdict. Tempting, because it is available for our exact tracts, and misleading if used carelessly. The adult asthma estimate for the east side tracts is a model prediction, not a count, and it concerns adults. It can support a statement that adult asthma is predicted to be more common on the east side, clearly labeled as modeled; it cannot support any statement about children. A modeled figure should never sit in a sentence written as if it were counted.
Source 3: Behavioral Risk Factor Surveillance System
What it is. A state-based telephone survey of adults, conducted with federal support, which asks about asthma and other conditions. Some states add an optional module about asthma in children in the household.
Finest unit. Reliable estimates are generally available at the state level and for larger counties; smaller areas require modeling.
Counted or modeled. Survey estimates, weighted to the state population.
Who is left out. People without telephones, people in institutions and, unless the child module is used, all children. Response rates vary by group, which weighting can only partly correct.
Verdict. Useful for state-level adult asthma prevalence and, where the child module exists, for state-level child estimates. It cannot resolve the east side.
Source 4: National Survey of Children's Health
What it is. A federally sponsored survey in which parents report on their children's health, including current asthma and its severity.
Finest unit. State.
Counted or modeled. Survey estimates.
Who is left out. Children whose parents do not respond; response is lower in some groups, which weighting partly addresses. Children in institutional care.
Verdict. The best national source for how common childhood asthma is, by state and by family characteristics such as income and insurance. It can show whether our state's childhood asthma prevalence is high, and whether children in low-income families have more asthma nationally. It cannot say anything about the east side.
Source 5: National Health Interview Survey
What it is. A long-running household interview survey of the civilian noninstitutionalized population, including children.
Finest unit. The nation and large regions.
Counted or modeled. Survey estimates.
Who is left out. People in institutions, active-duty military and people without a fixed household.
Verdict. Useful for national trends and for differences by race, ethnicity and income nationally. Too coarse for any local comparison.
What the Review Shows
No national source can tell us how many east side children have asthma. The only source that resolves our tracts for children is the one we already use, and it counts visits, not children. PLACES resolves our tracts but only for adults and only by modeling. The surveys that ask about children resolve only to the state.
That gap shapes the next step. To answer whether the east side has more children with asthma or worse-controlled asthma, the county will need local data: school nurse asthma records, Medicaid claims for asthma controller medications by tract, or a local survey. The national sources are best used for context: the state emergency department databases to compare our visit rates with other places on the same definition, and the children's health survey to place our state's childhood prevalence nationally.
What the Review Changes in the County's Plan
The review changes the county's data plan in three ways. First, the county will request an agreement with the state Medicaid office to receive tract-level counts of children with asthma diagnoses and controller medication fills, which would show whether east side children with asthma are receiving controller therapy. Second, the school district's nurses already record which students have asthma action plans on file; aggregated by school attendance zone, those records would give a rough count of children with diagnosed asthma. Third, the county will stop using the PLACES adult asthma estimate in presentations about children, where it had appeared in a slide last year without a label saying it was modeled and adult. None of these steps requires new national data. Each uses local records that already exist, which is where the national review points.

What the NR 550 Week 4 assignment asks for
This week asks you to evaluate national data sources relevant to your population health issue. The prompt usually wants the sources, what each measures, its methods, strengths and limitations, and how it applies to your local question. Start with the local question the sources must serve. For each source, state the finest geographic unit it reports, since that decides whether it can speak to your area at all. Say whether local figures are counted from records or modeled from surveys, and never let a modeled figure stand in a sentence written for a count. Name who the sampling frame leaves out, such as children, people without phones or people in institutions. Give each source a verdict about use. End with what the review changes in your plan. Cite sources and methods papers in APA 7.
How this NR 550 Week 4 example is built
The review opens with two questions the local data cannot answer. Five source sections follow, each with what it is, its finest unit, whether it counts or models, who it leaves out and a verdict. State emergency department databases count visits and are the right national comparison for visit rates. PLACES resolves tracts but models adult asthma from survey data, with a methods paper on multilevel regression and poststratification cited, so it cannot describe children. The adult telephone survey, the children's health survey and the national interview survey resolve only to states or larger areas. A summary finds no source can count east side children with asthma. A final section lists local records to use instead and retires a mislabeled slide.
NR 550 Week 4 rubric: what full points look like
Data source reviews are generally evaluated on accurate description of sources, critical appraisal of methods and coverage, relevance to the local question and practical conclusions. Testing every source for resolution, counting versus modeling and sampling frame shows systematic appraisal. Recognizing that a small-area estimate is modeled, and that it may cover a different population, prevents a common and serious error. Naming who each frame excludes shows understanding of survey limits. Verdicts tied to the local question are more useful than general strengths and weaknesses. A conclusion that changes the data plan, including local sources, shows the review was put to work. Methods papers and official source descriptions cited in APA 7 support the review.
NR 550 Week 4 help from the desk
Reviews often describe national sources in general terms without asking whether they can answer the local question. Start with the question. Another weakness is treating modeled small-area estimates as counts; label them clearly. Some students overlook who a survey leaves out, such as children in an adult survey. Check the frame. Avoid listing every possible source; choose the ones relevant to your outcome and population. Give each a verdict about use, not only strengths and weaknesses. Be honest when national data cannot help, and say what local data could. Check source details against official documentation rather than secondary summaries, since survey methods change over time.

NR 550 Week 4 questions, answered
How do I tell whether an area figure is counted or estimated?
Look for an interval printed beside it. Counts from a complete record system rarely carry one; estimates almost always do, because the producer knows the figure came from a model. The technical documentation will also give sample sizes per area, and where those drop into the dozens for a county, whatever is published for that county has been borrowed from somewhere else.
The national source and my local source disagree. Which one is right?
Usually neither is wrong. They count slightly different things, over different periods, at different depths, and one of them may be modeled. The review earns its marks by saying what each source is able to answer rather than by declaring a winner. If your write-up has to pick one, pick the one measured at the depth your question lives at and state the trade you made.
Can I review more than one national source?
Yes, if each gets the same examination. The common failure is two sources quoted in one sentence at two different geographies, which reads as thoroughness and marks as carelessness. Where your prompt asks for several, keep them in separate passes and add a short paragraph on where they agree, where they do not, and which of the differences is a measurement difference rather than a real one.
Where can I find a free NR 550 Week 4 sample paper?
The five-source national data review is displayed above as the NR 550 Week 4 sample, available in full. If your topic needs different sources, name the outcome and population and a review testing each source can be prepared.
What does counted or modeled mean in NR 550 Week 4?
Whether a local figure is a tally of records or a prediction from survey data and similar places. The sample shows that PLACES tract estimates are modeled and cover adults only.
