A 50 Percent Rise in New Hypertension Diagnoses, or a Bigger Denominator?

Composite health center and figures written for a model post. No real organization is described.
Initial Post
Our center's leadership reported last month that hypertension is "surging" among our patients, because new diagnoses rose from 212 to 318, a 50 percent increase, in the year our second site opened. The 106 extra diagnoses are real work for real clinicians. The question is whether they mean that risk is rising, and that depends on the denominator.
Year 1: new diagnoses 212; adults seen 9,640; adults already diagnosed on January 1, 1,740; adults at risk 7,900. Year 2: new diagnoses 318; adults seen 15,300; adults already diagnosed on January 1, 2,900; adults at risk 12,400.
The first candidate denominator is adults seen: 212 / 9,640 = 22.0 per 1,000, then 318 / 15,300 = 20.8 per 1,000. That is better than a raw count, but it is still the weaker choice, because a person diagnosed years ago cannot become a new case and should not sit under an incidence figure. Removing adults who already carry the diagnosis leaves the population actually at risk, and the rate among them barely moves: 212 / 7,900 = 26.8 per 1,000, then 318 / 12,400 = 25.6 per 1,000. Incidence counts new cases among people who could become cases (Celentano & Szklo, 2019).
So the conclusion splits in two. The volume is real: 106 more new diagnoses means more follow-up visits, and that supports hiring a second nurse practitioner for hypertension management. The risk is not rising: the incidence among adults at risk is flat, so a community screening campaign premised on rising incidence would rest on the wrong number. One gap remains. The new site may serve an older population, and hypertension incidence rises with age, so the next check is an age-specific breakdown before anyone concludes that risk is unchanged in every group (Centers for Disease Control and Prevention, 2012).

Your emergency department visit count for asthma doubled, but your hospital also added a pediatric wing that year. What was the denominator for each year? Children living in the service area might give a different picture from total visits.

I like that you used a rate rather than a count. One question: does your population at risk exclude people who already had the condition at the start of the year? If not, your figure might be closer to a mix of prevalence and incidence.

How this MN505 Unit 1 example is structured
The argument runs from the number everyone quoted to the number that answers the center's actual question. It opens on the leadership claim, that hypertension is surging among patients, and grants that 106 more diagnoses is real work for real clinicians. Then the base is rebuilt in stages. Adults seen is the first candidate and is rejected, because a person diagnosed years ago cannot become a new case and should not sit underneath an incidence figure. Subtracting prevalent cases gives the population at risk, and the post names that as the denominator the claim needed. With both rates on the page, the conclusion splits: volume justifies a second nurse practitioner for follow-up, while risk gives no support to a community screening push premised on rising incidence. One sentence flags a remaining gap, that the new site may serve an older population, so an age breakdown is the next check.

MN505 Unit 1 questions, answered
Why remove people already diagnosed from the denominator?
Because incidence measures new cases arising among people who could become one. A patient diagnosed with hypertension three years ago is no longer at risk of a first diagnosis, so leaving that patient in the base dilutes the rate. For a condition as common as hypertension in adults, the difference is large enough to change a conclusion, which is why the example subtracts them in its own table row.
Is a count ever the right number to report?
Yes, when the question is about workload, supplies or staffing. A clinic planning follow-up visits needs to know how many patients are coming, whatever their risk. The mistake is using that count to argue that risk has changed. The example keeps both figures and assigns each to the decision it can support, which is the move instructors usually reward in this first post.
What if my Unit 1 prompt gives no denominator at all?
Then noticing the gap is part of the answer. A strong post names the population that ought to sit underneath the count, says where a figure for it could come from, such as a census table or a clinic panel report, and sketches how the conclusion might shift once it is found. Spotting the missing base usually scores better than inventing a number to fill it.
