About [63] percent of the rise comes from which patients arrived and the rest from severity tiers; the HI410 Unit 5 analysis then traces much of that remainder to one diagnosis. Searches like "hi 410 unit 5 assignment example", "hi410 unit 5 sample" and "hi410 unit 5 example" land here.
What a finished HI410 Unit 5 case mix index analysis looks like
Three tables and about five pages of prose. The first table gives both years: total relative weight, discharges and the resulting index, [3,178.80] over [2,600] and [3,408.00] over [2,730]. The second holds four families by tier, with counts for each year, and shows joint replacement volume climbing from [260] to [325] while heart failure and pneumonia hold roughly steady in size but move toward their top tiers, each from about [17.5] percent of cases to [25.0]. A counterfactual index of [1.2389], year-two volumes at year-one tier shares, separates the two effects. The third table lists stays whose only major complication was severe malnutrition: [9] in the first year, [47] in the second, [31] of the added cases from one hospitalist group, with dietitian consult volume flat.
How a HI410 Unit 5 example is structured
The analysis opens by refusing the committee's framing in one sentence: a rising index has three possible causes, and the data must choose among them. The decomposition comes next. Holding year-one tier shares constant while applying year-two volumes gives the counterfactual index, and the gap between it and year one, [0.0163], is attributed to case mix in the ordinary sense, mostly the growth in surgical joint cases. The remaining [0.0095] comes from tier movement inside families. That remainder is then tested two ways. Spread across many physicians and many conditions, tier movement is consistent with the documentation program launched early in year two. Concentrated in one condition and one group, without matching clinical indicators, it reads as a drift signal. Here it is both, and the recommendation is a focused review of the malnutrition stays, not a celebration.
Three causes named before any number
Three explanations, more acutely ill patients, more complete records and drift in code assignment, are defined in the opening, each paired with the evidence that would favor it, so the data sections answer a question already posed.
A counterfactual year
Applying year-one tier shares to year-two volumes isolates the part of the rise that arrived with the patients. The method takes three sentences, and the arithmetic sits in a footnote.
Joint cases carry the mix effect
Surgical joint volume grew by a quarter, and those stays weigh far more than a medical admission, which accounts for most of the [0.0163] without any change in how records were written.
Two top tiers, one diagnosis
Heart failure and pneumonia both moved toward their highest tiers. Setting aside stays where severe malnutrition was the sole major complication erases more than half of that movement.
Review, not celebration
The recommendation asks for a sampled clinical validation review of the malnutrition stays against the facility's adopted criteria, and states in advance what result would confirm the documentation explanation instead.
Where marks go in HI410 Unit 5
The heaviest loss goes to papers that explain the rise with one cause, most often better documentation, when the data support more than one. Index values compared without discharge counts lose marks next, since a small change in volume can move an index on its own. Decompositions that compute nothing lose ground: saying that mix and severity both contributed, without a counterfactual or a share, leaves the central question open. Drift is sometimes treated as an accusation and avoided entirely, which costs marks, because the criteria ask for it to be weighed. The opposite error also costs: calling the malnutrition pattern fraud. The finished analysis calls it a signal, names the review that would test it and says what finding would clear it.

HI410 Unit 5 questions, answered
Is a rising case mix index good news?
It depends on the cause. An index that rises because the hospital began treating more complex patients reflects real work, and one that rises because documentation now captures conditions that were always present reflects a more accurate record. An index that rises because codes are assigned without support is an audit exposure. The example treats the number as neutral until the cause is known.
Why use a counterfactual instead of comparing families one by one?
Family-by-family comparison shows where tiers moved but not how much of the total rise each movement explains. The counterfactual answers that directly: it asks what the index would have been if patients had changed and recording had not. It is a simple weighted average, and the example shows the arithmetic so it can be repeated on other figures.
Can the analysis name the physician group?
Within a composite case, the example calls it one hospitalist group and gives no names. In practice, drift findings go to compliance and to the physician adviser before anyone is identified in a report. A paper that names individuals on the strength of a count has gone beyond what the evidence supports, and many rubrics mark that down as overreach.
