Strengthening systems of care for people with or at risk for HIV, HCV and opioid use disorder: a call for enhanced data collection.

It is difficult to assess the strategies needed or the progress made towards increasing treatment access and decreasing the burden of disease without the ability to construct an accurate baseline. Using integrated COCs with relevant benchmarks can not only guide public health planning, but also provide meaningful targets for intervention.KEY MESSAGESWhile HIV COCs are available for most states at least annually, they are not disaggregated for populations with co-occurring OUD or HCV.Data to calculate HCV COC are not available and data to calculate OUD COC are partially available, but only for specific payers.States do not have systems in place to measure the scope of the syndemic or to identify targets for quality improvement activities.
