Some of the clinical achievements that contributed to this significant change include
- Increased use of ACE inhibitors or angiotensin receptor blockers (ARBs) (from 42% to 74% over a five-year period)
- Reduced average blood pressure among hypertensive patients (to 133/76 mm Hg)
- Improved blood glucose control (by 10%)
- Increased testing for kidney disease among older patients (50% higher than the rest of the Medicare diabetes population).3
HOW THEY DID IT
This is not rocket science. The IHS staff integrated both population- and team-based approaches to achieve a more impressive decrease than ever could have been expected. In retrospect, perhaps this success should not come as such a surprise—many religious beliefs held by Native Americans focus around society, communal harmony, kinship, and cooperation.
The population health approach focused on promoting the wellness of the entire community and connecting people to local resources, including healthy food, transportation, housing, and mental health care. In the team approach, IHS medical experts implemented strategies to improve patient education, community outreach, care coordination, health outcome tracking, and access to a wide variety of health care providers.3,5
In a place like Alaska—where the northernmost city, Barrow, is more than 700 miles (two hours by plane) from Anchorage, and the southeastern Annette Island is more than 1,000 miles (six hours by plane) from the capital—this can be an especially challenging prospect. To reduce travel burden for rural patients, the IHS sponsors a diabetes team that travels from village to village. Nephrology services are not included in these field visits, however, so the kidney team relies heavily on telehealth. This requires extensive clinic staff coordination, as well as equipment and knowledgeable information systems support teams.
Other challenges require educational and logistical solutions. As noted, the use of ACE inhibitors and ARBs increased through the IHS’s efforts—and contributed to the delayed progression of diabetic kidney disease—but those additional prescriptions necessitate patient education. Understanding of these medications can be limited; many rural patients trust that when the bottle is empty, their practitioner has treated and cured their disease—mistakenly believing that no refills are needed. And even when the need to continue the prescription is understood, rural clinics may have difficulty tracking appointments and prescriptions written by providers at specialty clinics in Anchorage, making ongoing refills an issue.
