Abstract
|
Before
For many government safety net programs, beneficiaries must regularly demonstrate eligibility to avoid losing benefits. The objective of this field experiment is to identify the effect of outreach strategy on beneficiaries’ maintenance of Medicaid enrollment. The topic is timely because an upcoming policy change after the end of the COVID-19 public health emergency (PHE) will increase demonstration of eligibility requirements for Medicaid beneficiaries nationwide. The experimental population includes an estimated 168,000 cases (members of a household who applied for Medicaid together) in Wisconsin enrolled in fee-for-service Medicaid who must renew or lose their coverage after the end of the public health emergency. The implementing organization is Covering Wisconsin, the navigator organization contracted by the Wisconsin Department of Health Services to conduct outreach to these beneficiaries. Experimental arms will vary the number of outreach messages (1 vs. 2) and the modality of assistance offered (texting with a chatbot vs. calling a hotline to speak with an assister). This research will identify novel, scalable outreach methods to help low-income people maintain access to benefits.

After
For many government safety net programs, beneficiaries must regularly demonstrate eligibility to avoid losing benefits.

The topic is timely because an upcoming policy change after the end of the COVID-19 public health emergency (PHE) will increase demonstration of eligibility requirements for Medicaid beneficiaries nationwide. The experimental population includes an estimated 168,000 cases (members of a household who applied for Medicaid together) in Wisconsin enrolled in fee-for-service Medicaid who must renew or lose their coverage after the end of the public health emergency. The implementing organization is Covering Wisconsin, the navigator organization contracted by the Wisconsin Department of Health Services to conduct outreach to these beneficiaries. The intervention arms will vary the modality of outreach (postcard, text message, or outbound call), the content of the outreach (encouraging a call to a hotline vs. encouraging a text message that connects them with a chatbot) offered, and the number of outreach messages (1 vs. 2); the chatbot can also be used to schedule a call with an assister. This research will identify novel, scalable outreach methods to help low-income people maintain access to benefits.

Power calculation: Minimum Detectable Effect Size for Main Outcomes
|
Before
The study has 80% power to detect a 0.66 percentage point change in enrollment rates due to changes in outreach repetition or suggested modality for contact.
|
After
The study has 80% power to detect a 0.69 percentage point change in enrollment rates due to changes in outreach repetition or suggested modality for contact.
