HI560 Unit 4 data quality assessment example

Health Care Data Analytics Purdue University Global Free custom sample in 24 to 48h

Eight of 100 sampled South records coded as first births belonged to women who had delivered before. That single finding, drawn from a chart-and-worksheet comparison, decides much of the HI560 Unit 4 data quality assessment for Kestwick Health's composite delivery file, which asks whether the file is sound enough for the cesarean comparison at all, and on what repairs.

What this page holds

Can a delivery extract with misrecorded parity, borrowed weights and a defaulted onset field support a two-hospital cesarean comparison? Yes, after three repairs, this HI560 Unit 4 assessment concludes. Searches like "hi 560 unit 4 assignment example", "hi560 unit 4 sample" and "hi560 unit 4 example" land here.

What a finished HI560 Unit 4 data quality assessment looks like

Six pages, give or take, with a findings table at the center and a verdict at the end. Checks follow the harmonized framework Kahn and colleagues published in 2016: conformance, completeness and plausibility. Automated checks run across all 6,412 rows first, catching 14 deliveries dated before admission and 29 gestational ages outside 20 to 44 weeks. A validation sample follows, 100 NTSV candidates per hospital compared field by field with the birth certificate facility worksheet and the chart. Parity disagreed on 8 South records and 2 North. At South, 18 body mass index values came from the admission weight rather than a pre-pregnancy one. Labor onset read spontaneous on 11 South records with an induction agent ordered before labor. Coded gestational weeks disagreed with the obstetric estimate on 6 records, two of them crossing the 37-week line.

How a HI560 Unit 4 example is structured

Quality is judged against one use, the NTSV comparison, so the assessment opens by naming the five fields that decide who enters the denominator and how the groups are adjusted. Each field then gets the same treatment: the check performed, the count found, the likely cause and the effect on the comparison's direction. Direction is the paper's distinctive move. Multiparous women coded as first births carry lower cesarean risk into South's denominator and pull its rate down; borrowed weights inflate South's apparent body mass index and make any adjustment explain too little of North's excess. Timeliness is treated separately, since December's abstract was 4 percent uncoded at extraction. The verdict follows: fit after reconciling parity, recomputing weight and rebuilding onset from medication orders. A last table shows South's rate moving from 22.4 to 23.5 percent once parity was reconciled.

Fit for which question

Parity, gestational age, plurality, presentation and labor onset decide NTSV membership and adjustment, so the assessment tests those five fields and declares every other column out of scope for now.

Conformance, completeness, plausibility

Automated checks over the whole file find impossible dates, out-of-range gestations and blank values; the counts appear by hospital with each rule written out so another analyst could rerun it.

Two hundred records read twice

A validation sample sets extract fields beside the birth certificate worksheet and the chart. Agreement is given as counts out of 100, not bare percentages, so the reader sees how small the sample is.

Which way each error pushes

Misrecorded parity lowers South's rate; admission weights shrink the apparent body mass index gap. Both errors flatter South, which is why the paper argues that repair must come before any test.

Repairs, and what they moved

Parity reconciled against the worksheet removed 61 South records from the NTSV denominator. South's rate rose from 22.4 to 23.5 percent, and the file was versioned before any later unit used it.

Where marks go in HI560 Unit 4

Assessments that judge data quality in general, without naming the question the data must answer, tend to score in the middle of HI560 rubrics. What instructors usually look for is a small set of decisive fields, each checked with a stated rule, counted by site and tied to its consequence. A validation sample against an independent source, here the birth certificate worksheet, usually earns more than automated checks alone, because range checks cannot catch a plausible wrong value. The direction of each error matters; a paper that finds problems but never says whether they inflate or shrink the comparison leaves the manager unable to judge. Blaming registration staff for a template default reads as misdiagnosis. Credit also follows a clear verdict with conditions, and a versioned file for every later unit.

HI560 Unit 4 questions, answered

What is a validation sample, and do I need one?

A set of records checked against an independent source, such as the chart, a registry or a certificate worksheet, to see whether plausible values are also correct. Automated checks find impossible values; only comparison finds wrong ones. If the prompt supplies a second source, use it. If not, say what source would be needed and why it matters for the question.

Which data quality framework fits health data analytics?

Kahn and colleagues' 2016 harmonized framework, built for secondary use of electronic record data, sorts checks into conformance, completeness and plausibility, which suits analytics well. AHIMA's data quality characteristics are common in HIM courses too. Whichever the course names, the framework should organize checks on the fields that matter for the question rather than generate a definition for every dimension.

Should the assessment fix the data or only report problems?

Report first, then describe any repair with its effect on the numbers, and keep the original file untouched. A versioned, repaired file lets later units state exactly which data they used. Where a repair is a judgment, such as recomputing weight from a different visit, say so and show the result both ways if the difference is large.
