Unit 2 Census Computation
[Instructor Name]
[Date]
The hospital, its week and its counts are composite; the census definitions and the sources cited are real.
Definitions Used
Census: the number of inpatients present at the official count time, midnight at this hospital. Inpatient service day: one patient present at the census hour, plus one for each patient admitted and discharged the same day, since that patient used a day of service but was never present at midnight. Average daily census: total inpatient service days for the period divided by the number of days. Newborns in bassinets are reported on their own line, apart from adults and children, as is standard in hospital statistics, and are excluded here (Horton, 2017).
Starting Point
Assumption: the admission, discharge and death list for the week is complete. Had the source given only nightly census figures and no movement, inpatient service days would equal the sum of those counts plus any same-day patients it named.
Midnight census on Sunday, the night before the week begins: 139 adults and children.
The Week
1. Monday: 139 plus 24 admissions minus 23 discharges, including one death, gives 140.
2. Tuesday: 140 plus 19 minus 21 gives 138.
3. Wednesday: 138 plus 26 minus 23 gives 141.
4. Thursday: 141 plus 20 minus 22 gives 139.
5. Friday: 139 plus 25 minus 22 gives 142.
6. Saturday: 142 plus 14 minus 19 gives 137.
7. Sunday: 137 plus 18 minus 15 gives 140.
Sum of the seven midnight counts: 977.
Newborns, Kept on Their Own Line
The nursery's midnight counts for the same seven nights were 11, 12, 12, 10, 13, 12 and 14, for 84 newborn service days and an average of 12.0 newborns a night. These figures stay beside the main count and never inside it, so occupancy for beds and for bassinets can each be computed from the right numbers.
Same-Day Patients
Eight patients were admitted and discharged on the same day during the week: three on Monday, one on Tuesday, two on Wednesday, one on Thursday and one on Friday. Each adds one inpatient service day, because none was present at midnight.
Results
Total inpatient service days: 977 plus 8 equals 985.
Average daily census: 985 divided by 7 equals 140.7. A worksheet that summed only the midnight counts would report 977 days and miss every patient who came and went before midnight.
Transfers Within the Hospital
Twelve intrahospital transfers occurred during the week, mostly from intensive care to medical floors. They do not change the hospital-wide census, because the patient leaves one unit and enters another. They matter only for unit-level census, where each transfer is a discharge from one unit and an admission to another. The worksheet checked that no transferred patient was counted twice at midnight by comparing the unit totals with the hospital total each night.
Why the Census Matters
Census and inpatient service days feed occupancy, staffing ratios and budget projections. Hospitals plan beds against average census, yet research on bed capacity shows that units sized to run near a high average occupancy face frequent delays when admissions arrive unevenly, so the daily pattern behind an average is as important as the average itself (Green, 2002). This week's counts ranged from 137 to 142, a narrow spread, but a winter week at the same hospital ranged from 151 to 178, the kind of swing that simulation studies of emergency admissions show can overwhelm a hospital whose average looks comfortable (Bagust et al., 1999).
Checks Before Reporting
The midnight count reported by nursing each night was compared with the count rebuilt from admissions and discharges. On Wednesday the nursing count read 142, one more than the rebuild. The difference traced to a patient discharged at 11:40 p.m. whose discharge was entered after midnight. The rebuilt figure of 141 was used, and the discharge time was corrected in the system, since every entry in the record must carry an accurate date and time (42 C.F.R. § 482.24, 2024). A census rebuilt from movement should always agree with the count taken on the units; when it does not, the reason must be found before the figure is reported.

HI230 Unit 2 instructions, in plain terms
Unit 2 normally supplies a starting census and a list of daily movement, then asks for each night's count, total inpatient service days and the average daily census for the period. Some prompts add transfers between units, newborns, deaths or patients who arrive and leave on the same day, each of which tests a counting rule. Expect to define your terms before you calculate, to show every day's arithmetic rather than only the totals, and to keep newborns apart from adults and children. A few sections also ask why the census matters to staffing or budgeting, which calls for a short paragraph with a source. The finished worksheet should let a grader follow the week line by line without a calculator. If your prompt gives only midnight counts and no movement, say so and explain how that changes the total.
Inside the HI230 Unit 2 example
The worksheet starts with four definitions, from census to average daily census, and a one-line assumption that the movement list is complete. The starting count of 139 comes next, followed by a numbered list of the seven nights, each showing the previous count plus admissions minus discharges and deaths. The newborn line reports 84 service days for the nursery and keeps them out of the main total. The eight same-day patients get their own section, and a margin note explains why they would vanish from a census built on midnight counts alone. Results come next in two lines, then a section on transfers that shows they change unit counts but not the hospital total. Two cited paragraphs link the census to bed planning, and a final check reconciles the nursing count with the rebuilt figure.
Reading the HI230 Unit 2 grading rubric
Rubrics for census exercises in HI 230 reward accuracy first and clarity second. Most of the points sit on correct nightly counts, the right treatment of same-day patients and deaths, and an average daily census computed from service days rather than from admissions. Further credit goes to clean definitions stated before the arithmetic, so that the grader knows which rules you applied. Newborns reported separately and transfers handled without double counting usually earn their own share of the points. Instructors also value a brief statement of why the figure matters, supported by a cited source. Presentation counts: numbered days, labeled totals and results rounded to one decimal place. A worksheet that reaches the right total with no visible steps may lose points, since the method is what the unit is testing.
HI230 Unit 2 help: mistakes that cost points
The error graders see most often is summing the midnight counts and stopping, which loses every patient who came and went in a single day. Add same-day patients as their own line. Another is treating a death as something other than a discharge, which leaves the next night's count one too high. Students also count internal transfers as admissions and discharges at the hospital level, inflating movement without changing the census, or fold newborns into the adult total. Check each night by subtracting before you add up the week. We can prepare a census worksheet for your own data if you share the movement list and the counting rules your instructor uses. Finally, carry the average to the decimal place your key expects, because a census of 140.7 rounded to 141 may cost a point.

HI230 Unit 2 questions, answered
Is a patient admitted and discharged the same day really a full service day?
Yes, by the standard definition used in hospital statistics. That patient never appears in a midnight count, so without the same-day rule the care would vanish from the census entirely. The example adds such patients to the day's service days and shows the check line, so a grader can see they were counted once, not twice and not zero times.
Why keep newborns separate?
Because hospital statistics conventionally report newborns in bassinets apart from adults and children, and most keys expect that split. Folding them in inflates the census and distorts later rates built on it, especially occupancy, where bassinets have their own count. The example keeps a small newborn block beside the main table so both figures are available without either contaminating the other.
What if my data gives only midnight census figures?
Then service days equal those counts plus any same-day patients the data identifies, and if it identifies none, the census and service days match. The example notes that assumption in a line above the table. If the prompt gives movement instead, the midnight counts have to be built row by row, which is how the example's table works.
Where can I find a free HI230 Unit 2 sample paper?
The complete Unit 2 census computation, with seven nightly counts, eight same-day patients and an average daily census of 140.7, is on this page.
How do you calculate average daily census?
Add up the inpatient service days for the week or month, then divide by how many days it covers. Service days are the midnight counts plus one for each patient admitted and discharged on the same day.
