Controlled, Uncontrolled and Unseen: A Hypertension Burden Brief for Bluestem Health Network Managers

Who Is Counted

This brief describes adults with hypertension in Bluestem Health Network, the invented rural network of nine clinics used in this course. The population is adults whose primary care is attributed to one of the network's clinicians, aged 18 to 85, the age range used by the HEDIS Controlling High Blood Pressure measure (National Committee for Quality Assurance, 2024), who have hypertension on their problem list or recorded as a diagnosis at two visits in the past two years. Control is judged by the most recent blood pressure in the record, using the measure's threshold of below 140/90. All counts are illustrative and described in relative terms.

Three Groups

Table 1 splits the population three ways.

Table 1

Adults With Hypertension by Control Status (Illustrative)

The unseen group is not counted as controlled or uncontrolled, because the network does not know their pressure.

The Unseen Group

Standard reporting would fold the unseen group into the denominator of a control rate and count them as not controlled, or would leave them out entirely. Both choices hide them. They are adults the network knows have hypertension but has not seen in a year or more. Some have moved or switched providers; some are well and simply stopped coming; and some are uncontrolled and do not know it, since high blood pressure rarely causes symptoms. Their share is large enough that any program working only with adults who come to clinic would miss a fifth of the population. Registries that let a team see who is overdue, not only who is present, are a core element of effective chronic care (Wagner et al., 2001).

By Clinic

Table 2 repeats the split for each clinic, grouped by county.

Where the Unseen Live

Plotted on a map of the five counties, the clinics with the largest unseen shares sit in the two most remote counties, the fourth and fifth, which are farthest from the hub town and have the fewest clinic hours per resident. In those counties, nearly a third of adults with hypertension have had no reading in a year. The uncontrolled share is similar across clinics. The difference between the hub and the remote counties is not mainly in how well pressure is controlled among adults who are seen, but in how many adults are not seen at all.

Consequences

Uncontrolled hypertension is a leading cause of stroke and heart failure, and the network's hospital sees both. In the past year, the hospital's discharge records show that most patients admitted with stroke or new heart failure had hypertension on their problem list beforehand, and a substantial share had either an uncontrolled last reading or no reading in the year before admission. These figures are illustrative but the pattern is typical: much of the network's most expensive and most disabling care begins with blood pressure that was not controlled. National trends show control declining in recent years after long improvement (Muntner et al., 2020), which suggests the problem will grow without deliberate effort.

What the Brief Suggests

Three points follow for managers. First, report hypertension control in three groups, not two, so the unseen are visible on every dashboard. Second, any blood pressure program should start with the unseen group in the remote counties, since that is where the largest gap lies and where clinic-based efforts alone will not reach. Third, the program will need ways to obtain blood pressure readings outside the clinic. Home blood pressure monitoring has been shown to improve control, especially when combined with support from clinical staff (Uhlig et al., 2013), and could bring readings from the unseen group into the record without requiring a drive to the clinic. The Week 4 memo compares care models that could deliver such support.

Limits

The count depends on the problem list, which may miss adults with high readings who were never diagnosed, and includes some adults who have moved away but remain attributed. The latest reading is a single measurement, which can be high because of anxiety or a rushed visit. The clinic-level shares come from small populations at the smallest clinics and will vary from year to year. Despite these limits, the pattern of a large unseen group concentrated in remote counties is strong enough to guide planning.

What Managers Can Do Now

Some steps need no new program. Clinic managers can pull the list of their own unseen patients from the registry each month and ask front desk staff to offer a blood pressure check whenever one of those patients contacts the clinic for any reason, such as a prescription refill or a child's visit. Nurses can record blood pressure readings taken at pharmacies or other clinics when patients report them, with the source noted, so that the record reflects care received elsewhere. Managers at the two remote counties' clinics can review whether clinic hours fit working adults, since a clinic open only on weekday mornings will see few people who work those hours.

These steps will not close the gap on their own. They will, however, test how many unseen patients can be reached with modest effort and give the network an early estimate of how large a dedicated program needs to be. They also start the habit, essential to any population program, of looking at the registry for people who are not coming in rather than waiting for them (Wagner et al., 2001). The results of this first month should be reported back to the planning group along with the next update of Table 1.
