HIV Care Continuum (Treatment Cascade)

Updated July 2017

The care continuum, sometimes referred to as treatment cascade, is a calculation of how many Minnesotans diagnosed with HIV are initially linked to care, retained in care, (receiving HIV medical care in 2016), and achieve viral suppression. It is an important tool in measuring the successes of the national HIV/AIDS strategy in Minnesota.

The CDC provided guidance on how to make this calculation, but we modified it based on input from HIV prevention and care providers in Minnesota. It was discovered that health care providers in Minnesota typically only do one lab test per year for patients whose HIV infection is well managed instead of two lab tests that the CDC calculation used. With this modification, we were able to get a better sense of HIV care in Minnesota.

It's important to remember that this data is a point in time and not cumulative. It is a snap shot of how HIV positive persons' clinical care occurred in a given year. We have been calculating the care continuum since 2013. Below is the summary of the 2016 care continuum for people diagnosed through 2015.

The goal of HIV treatment is to achieve viral suppression, meaning the amount of HIV in the body is very low or undetectable. This is important for people living with HIV to stay healthy, live longer, and to reduce their chances of passing HIV to others.

Percentages of persons with HIV engaged in selected stages of the continuum of care, 2016

Percentages of persons with HIV engaged in selected stages of the continuum of care

aDefined as persons undiagnosed (estimate 1,100 [570-1,500], 95% CI) and persons diagnosed (n=8,297) aged 13 or more with HIV infection (regardless of stage at diagnosis) through year end 2015, who were alive at year end 2016.

bDefined as persons diagnosed aged 13 or more with HIV infection (regardless of stage at diagnosis) through year end 2015 who were alive at year-end 2016.

cCalculated as the percentage of persons linked to care within 30 and 90 days after initial HIV diagnosis during 2015. Linkage to care is based on the number of persons diagnosed during 2015 and is therefore shown in a different color than the other bars with a different denominator.

dCalculated as the percentage of persons who had ≥1 CD4 or viral load test results during 2016 among those diagnosed with HIV through year end 2015 and alive at year end 2016.

eCalculated as the percentage of persons who had suppressed viral load (≤200 copies/mL) at most recent test during 2016, among those diagnosed with HIV through year-end 2015 and alive at year end 2016.

Calculated as number of persons who had suppressed VL (≤200 copies/mL) at most recent test during 2016, among those who were retained in care during 2016 (5,253/5,872).
