Abstract
Given the large numbers of people with HIV (PWH) with Medicaid coverage, it is important to understand the patient experience with Medicaid. Understanding experiences with and attitudes around the program have important policy and clinical implications. The objective was to understand the patient perspective of PWH in Virginia, who transitioned to Medicaid in 2019 due to Medicaid expansion. English-speaking PWH who gained Medicaid due to Medicaid expansion in 2019 were recruited at one Virginia Ryan White HIV/AIDS Program clinic. The goal was to enroll >33% of those who newly were on Medicaid for 2019. Participants were surveyed about demographic characteristics, and semistructured interviews were performed. Descriptive analyses were performed for cohort characteristics. Using qualitative description and an open coding strategy, codebooks were generated for the interviews and themes were identified. The cohort (n = 28) met our recruitment goal. Most participants had positive feelings about Medicaid before enrollment (general: 68%; good for general health: 75%, and good for HIV care: 67%) and after enrollment (general: 93% and good for HIV care: 93%). All participants expressed incomplete understanding about Medicaid before enrollment. Seventy-nine percent needed outside help to complete enrollment. Approximately 40% described overlaps of Medicaid with other insurance/payers or gaps in insurance coverage when transitioning from one insurance/payer (such as AIDS Drug Assistance Program [ADAP] medication provision and ADAP-subsidized insurance) to Medicaid. Participants suggested more access or easier access to information about Medicaid and more explanation of Medicaid benefits would be helpful. Our findings indicate participants had mostly positive perceptions of Medicaid before and after enrollment. Even with enrollment help, participants voiced that dealing with insurance is hard. Medicaid and other programs should prioritize more access to information, smoother processes, and less burdensome enrollment/re-enrollment.
Background
Currently, 38
Beginning in 2014, all PWH with low income, who were Virginia AIDS Drug Assistance Program (ADAP) clients, were offered individual private plans or Qualified Health Plans (QHPs) purchased on the ACA Marketplace and funded by the Virginia ADAP. This program resulted in a significant increase in viral suppression 3 and was viewed favorably by patients in a three-clinic mixed-methods study. 4 When Virginia expanded Medicaid in January 2019, many PWH transitioned from ADAP-purchased QHPs to Medicaid. In Virginia, PWH choose a plan from one of six Medicaid Managed Care Organizations (MCO) within the first 90 days of coverage. They are covered by fee-for-service Medicaid for ∼2–6 weeks before the Medicaid MCO plans start. 5
As more states expand Medicaid, more PWH will shift off ADAP-purchased QHPs to Medicaid. 1 In addition, employment changes brought on by the COVID-19 pandemic 6 may result in more PWH transitioning from individual and/or employer-based private insurance to Medicaid. Our recent quantitative analysis demonstrated lower rates of viral suppression in 2019 for PWH who transitioned to Medicaid. 7 Given this observation, it is critical to understand the patient experience of PWH who transition to Medicaid Expansion. Our goal was to understand the patient perspective and health care experience of PWH in Virginia, who transitioned to Medicaid in 2019 due to Medicaid expansion.
Methods
Study setting, participants, and enrollment
Participants were recruited and enrolled from a nonurban academic-affiliated RWHAP clinic at the University of Virginia (UVA). Clinic patients are eligible for RWHAP-supported services with an income below 500% of the federal poverty level (FPL). Approximately 98% of the clinic population received RWHAP-supported services (2018–2019). Among those who did not have Medicare in 2018, 151 RWHAP clients were newly eligible for Medicaid in 2019 due to Medicaid expansion. Of those eligible, 77 (51%) enrolled. 7
This prospective study's goal for recruitment was to enroll at least one-third (≥26) of the RWHAP clients who newly enrolled in Medicaid in 2019 due to Medicaid expansion. The UVA Institutional Review Board approved this study. Participants recruited for the study were English-speaking PWH, had been seen at the studied RWHAP clinic at least once in both 2018 and 2019, did not have Medicaid as their primary insurance in 2018, and newly had Medicaid as their primary insurance in 2019. They were recruited over the phone or face-to-face before or after an HIV medical visit in a medical examination room to ensure privacy and confidentiality. Enrollment took place from February 2020 to June 2020. Participation in the study took approximately of min. Participants received compensation for their time. The study included a descriptive survey and an interview, both of which were administered verbally to minimize any barrier related to low literacy.
Cohort characteristics
Participants were surveyed with validated measurement tools, when possible. We collected age, self-reported gender, race/ethnicity, financial status (annual income as a percentage of the FPL), highest level of education completed, housing stability, 8 self-reported disability status, employment status, hours employed per week, transportation difficulties, travel time to HIV clinic, internet access, food security, 9 use of the Supplemental Food Assistance Program (SNAP), health literacy, 10 and mental health, including depressive symptoms, 11 problem drinking, 12 and illicit drug use. 13 Due to the onset of the COVID-19 pandemic during enrollment, we modified the survey in April 2020 to capture COVID-19 pandemic-related unemployment. We also collected years since HIV diagnosis, self-reported viral suppression status over the past 12 months, and self-reported current viral suppression status. Characteristics were used to provide additional context to the qualitative interviews and were hypothesis generating in nature.
Participant interviews
Semistructured interviews were designed to elicit participants' experiences about switching to Medicaid. Participants were asked about their perceptions before enrollment, during the enrollment process, and after enrollment. Interviews were conducted by two members of the study team, after training in interview methods. Interviewers had no prior relationship with the participants or involvement in their medical care. The interviewers followed the interview guide to ask questions in the same order for each participant. They offered specific prompts if needed for clarity and asked follow-up questions. All interviews were audio-recorded and transcribed verbatim, and then imported into Dedoose (SocioCultural Research Consultants, LLC) for analysis.
Qualitative analysis
Our analysis was guided by qualitative description. 14 A codebook was generated iteratively by the study team, using an open coding approach with constant comparison methodology to capture themes emerging from participants' experiences. During codebook development, interviews were coded independently by two reviewers and any discrepancy resolved by consensus. The codebook was refined until intercoder agreement of 0.74 was achieved, and thematic saturation was reached. The codebook was then applied to all interviews so code frequencies could be determined.
Themes were grouped within temporal categories to capture perceptions at time points of interest (before, during, and after enrollment). Additional categories included themes affecting participants at multiple time points and were cross-cutting in nature, such as social determinants of health. Participant-generated suggestions or recommendations for improvement in the Medicaid enrollment process were also classified and categorized. Participants' perceptions were rated as positive, neutral, or negative, when relevant. To maintain rigor, decisions regarding the analysis were made open to all members of the study team. 15
Results
Participant characteristics
Twenty-eight participants met the enrollment goal (≥26 participants). The participation rate was 47%. Cohort characteristics are described in Table 1. Participants had a median age of 43 [interquartile range (IQR) 32–53]. Sixty-one percent were black participants. Participants had been diagnosed with HIV for a median of 10.5 years (IQR 5.7–18.5). More than half (54%) had incomes at or under 100% FPL. Approximately one-third had unstable housing or stable housing concerns. About 40% reported being disabled. Six participants (21%) reported being employed with median hours of 35 (IQR 20–50) per week. Almost 80% of participants (n = 22) were unemployed. Of those 22, 8 (36%) reported they were looking for work. Of the 12 who enrolled during the COVID-19 pandemic, all reported being unemployed, with 4 (33%) attributing their unemployment to the COVID-19 pandemic. More than half (64%) the participants reported difficulty with transportation to HIV clinic. Participants reported a median travel time of 53 min (IQR 28–120) to HIV clinic. Fourteen percent had no internet access, and 25% had internet access only on a smartphone. Sixty-one percent endorsed depressive symptoms, one-quarter reported problem drinking, and one-quarter reported illicit drug use in the last year. Less than one-third were food secure. Almost 20% had marginal or inadequate health literacy. About 70% reported durable viral suppression for the past year. Eighty-six percent reported having a suppressed viral load at the time of enrollment.

Participant interviews
Perceptions of Medicaid pre-enrollment
In general, 19 participants expressed positive feelings about Medicaid before their enrollment, 15 neutral, and 2 negative (Table 2-A). For all quotes, participants' self-identified race, gender, and age group are stated, except for themes or race-gender categories with only one participant to preserve privacy. Participants could express mixed feelings, as discussed further below. Most participants (75%) felt having Medicaid improved one's general health. One explained their impression was positive “because I could see my regular doctor and I can get all my prescriptions that I need” (black male, 36–45). Of those who addressed whether Medicaid would impact HIV care (15), 10 felt Medicaid's effect would be positive, 4 neutral, and 1 negative. The most commonly expressed themes were better affordability/lower cost of Medicaid and access to care with Medicaid. For example, one participant stated, “it will help out people with their basically their care and kind of like their plans where otherwise they could not get the care they need” (black male, 26–35).

All participants expressed a lack of awareness or incomplete understanding about Medicaid before enrollment. As one stated, “I'm like a lost babe in the woods...I really am uninformed about it to be honest” (white male, 56–64). Others lacked confidence in being able to understand insurance: “when it comes to stuff like that I've never been good at it” (white male, 56–64). Some had a vague impression of Medicaid, but little specific knowledge: “I only know that it was for people who needed help with medical assistance and things like that but like what they offered and stuff like that I didn't really know” (Hispanic male, 26–35). Pre-enrollment perceptions included potentially stigmatizing beliefs that Medicaid is for marginalized individuals, such as those with low income.
Regarding their switch to Medicaid (Table 2-B), most participants (78%) expressed positive feelings, such as “I felt good because it was better than going to the Health Department, find out where I get my, you know, my meds from, that I could go to the hospital” (Hispanic male, 46–55). Only one expressed a negative feeling: “It just made me a little worried about the providers.”
For perceptions with positive, neutral, or negative ratings, some participants expressed more than one type in their interview (Table 3). For perceptions of Medicaid pre-enrollment, six participants expressed both positive and neutral feelings. One participant had positive impressions from others, “I had heard through the grapevine from other people that Medicaid was pretty good,” but also negative impressions they had heard, “the problem with Medicaid that it doesn't help a lot like if you work, especially when a person is sick and they have a lot of health issues” (black female, 36–45). One participant expressed positive, neutral, and negative feelings, sharing a variety of stories they had heard before enrollment and seeing both pros and cons, for example, “It's just that some people say government programs are a little bit slow but besides that some people say they give you a health plan” (Hispanic male, 26–35).
Cross-Query Analysis to Assess Mixed Feelings at Different Time Points of People with HIV in Virginia Regarding Transition to Virginia Medicaid in 2019 Due to Medicaid Expansion
Enrollment process
All participants reported having a formal source of information about Medicaid (e.g., at HIV clinic; Table 2-C). Many also used informal sources (54%) such as friends or family. Some also reported receiving information from Medicaid in the mail (39%). Many participants (79%) needed outside help to complete the administrative process of enrollment, such as from a case manager or social worker (Table 2-D). Most found the information they received to be clear and understandable (71%). Some still expressed difficulty, even with outside help, in navigating the process (25%).
When receiving help with the enrollment process, many participants deferred any decision-making about their plan to the person who assisted them. For example, “I had a case manager that walked me through everything and signed me up for the program” (white female, 46–55). Others expressed self-efficacy in making decisions for themselves (54%). In particular, participants spoke about making choices regarding their plan, based on lowest co-pays or best medication coverage.
When transitioning from one insurance/payer (such as ADAP medication provision and ADAP-subsidized insurance) to Medicaid, some participants encountered difficulty with overlap of Medicaid with other insurance or the Virginia AIDS Drug Assistance Program (11%) and problems with gaps in insurance coverage (32%) either at the time of initial enrollment or re-enrollment. Overlap led to administrative difficulty and confusion. For example, “when they stopped paying for one the Health Department then…it made it complicated because they still had me in the system as active even though I was inactive” (black male, 36–45). Gaps in coverage had a negative impact on participants' access to care and medications: “I don't know if I got it and if I'm gonna be approved for it so right now not having anything is affecting me being able to be seen, you know, or get medicine, things that I need” (black female, 46–55).
For the enrollment process, 18 participants had only positive impressions of the clarity of information they received and 4 had negative only (Table 3). For two participants, both positive and negative statements were expressed. For example, one had a positive experience with initial enrollment, but then was switched from one Medicaid insurance provider to another without understanding why or realizing that would happen. The other encountered a similar problem. Although initially feeling well informed about the enrollment process, they had a subsequent change in Medicaid insurance provider without warning or adequate explanation, causing difficulty obtaining their HIV medications from the specialty pharmacy.
Changes after enrollment
Most participants had no change in providers after Medicaid enrollment (22, 79%; Table 2-E). Three reported a change in HIV care provider and four in other specialist providers. One participant had to change oncology providers and reported a negative impact on their patient-provider relationship: “You build a connection with your doctor, you know, cause he knows you and you know him and I've been dealing with him for so long with my cancer and everything and trying to find someone new and start all over is, you know, is awful” (black female, 36–45).
Most had no change in HIV medication (75%) or non-HIV medication (61%). For those who had changes, these included method of getting medications (e.g., switching from pharmacy pick-up to mail order) or change in coverage for medications. Some gained more reliable access to medications, with subsequent improvement in adherence: “I'm using the same medication and I'm just taking it as scheduled” (black male, 56–65). Others encountered unexpected negative changes: “I thought everything I get is supposed to be free and my medicine's supposed to be free so that's why I'm mad now cause I have to pay for some medicines and some I shouldn't have to pay for” (black female, 46–55).
Almost all participants reported use of Ryan White services (96%). Some reported less utilization of Ryan White support after Medicaid enrollment, because of increased access to services now covered by Medicaid. However, even with Medicaid, Ryan White assistance was still needed to fill coverage gaps: “whatever my dentist doesn't get paid for then the Ryan White picks up” (black male, 36–45).
Although most participants reported no change to their medical care in general (68%), some experienced a change in access to services. Many of these changes were positive with increased access to care or gaining benefits they did not previously have, such as dental coverage. However, some experienced an increase in cost of care and difficulty with co-pays. As one stated, “Some appointments I don't go to because I don't have it, like things that I need to go to I can't go to like cause I don't know if they're gonna charge me and I can't afford to be garnished out of my check...so if I know it's not gonna cover it I'm not gonna go if it ain't life and death” (black female, 46–55).
Overall, most participants reported an improvement in their health after Medicaid enrollment (61%). Positive changes included improvement in management of HIV and other chronic conditions: “I think it's better and I think it's helped with me getting the things that I need with HIV” (black male, 46–55). Only one participant reported a worsening of health post-enrollment. This participant also experienced gaps in coverage due to difficulties with re-enrollment and reluctance to access medical care due to cost concerns.
People could express multiple perceptions toward Medicaid (totals >100%). Most perceptions of Medicaid post-enrollment were generally positive (Table 2-F). Twenty-six (93%) participants made positive statements about their post-enrollment feelings, such as “Medicaid has been very good for me” (black female, 36–45). Six expressed neutral feelings, mostly due to lack of change in care attributable to Medicaid: “nothing's changed so I guess it's fine” (black male, 36–45). One had negative feelings post-enrollment: “If I had a choice I would not have Medicaid.” Most felt Medicaid provided good care for PWH (93%), although two expressed room for improvement: “they could do better” (black female, 56–65).
Regarding their post-enrollment perceptions of whether Medicaid provides good care for PWH, 24 participants expressed positive feelings only, 2 neutral only, and 2 both positive and negative (Table 3). One with mixed feelings reported being satisfied with their coverage from Medicaid, but was encountering difficulties with their transportation assistance. The other was satisfied with the experience, but was concerned about a friend who had difficulty with HIV medication access on Medicaid.
Themes across time points
Themes across multiple time points included medication adherence, trust in providers, and social determinants of health (Table 4). Medication adherence was discussed by four participants. Some were able to improve adherence, due to more reliable access to medications with Medicaid. However, interruption in medication access due to insurance problems had a negative impact on adherence for others. Trust in medical providers and their care team was discussed by five participants. Confidence that the care team had their best interests in mind helped some participants through the enrollment process: “I just go wherever my case manager and my doctors and all thought are best” (white male, 56–64). Some who had a change in providers due to insurance coverage had difficulty re-establishing trust, especially when “meeting a whole new group of people and talk about like very sensitive information and stuff” (black male, 26–35). Of the social determinants of health, participants most frequently discussed transportation (79%). Assistance with transportation was generally considered a positive aspect of Medicaid; however, the process of arranging transportation did not always go smoothly, including unreliable rides causing participants to miss medical appointments. In addition, the logistics were difficult to navigate: “I had to request transportation five days ahead to get it paid for and then fax and do all this and I just think that that's stupid” (black male, 36–45). Many participants continued to use Ryan White services for transportation. Other challenges included food access/security, housing, mental health, and incarceration.

For all quotes, participants' self-identified race, gender, and age group are stated, except for themes or race-gender categories with only one participant to preserve privacy.
Participants' suggestions/recommendations
The most frequent category of suggestions from participants was related to information access (Table 5). Fourteen participants desired more access or easier access to information about Medicaid and 12 wanted more explanation of Medicaid benefits. Some felt better online access to information would be helpful, although not all would be able to take advantage. In particular, some participants expressed a need for more information about re-enrollment, to avoid gaps in coverage, and more warning about any change to their plans with explanation of the implications of any change. Other suggestions from participants included having more assistance with enrollment, improvements in the enrollment and re-enrollment processes, better coverage and lower cost to patients, improvements in the transportation assistance, and ensuring uninterrupted timely access to medications.

Discussion
Participants had mostly positive perceptions of Medicaid both before and after enrollment. Most felt that their own health improved after Medicaid enrollment and that Medicaid allowed PWH to have good care. Even with enrollment help, participants voiced that dealing with insurance is hard. This might have important consequences and may be why a quarter of participants self-reported a detectable viral load in the first year on Medicaid. Some suggestions from our participants to improve Medicaid enrollment included more access to information, smoother processes, and less burdensome re-enrollment. These suggestions can be used by any program/insurance that anticipates new PWH to enroll/re-enroll and may be helpful for the RWHAP and RWHAP case management/insurance assistance programs.
Positive aspects of Medicaid discussed by participants included the following: affordability of care, access to HIV care and other medical and dental care, access to HIV and non-HIV medications, and transportation assistance. From the perspective of patients, expansion of Medicaid seems generally needed to facilitate access to care.
However, some negative experiences were also reported. More than 40% raised the issue of either overlaps of Medicaid and other insurance/ADAP or gaps in insurance coverage when transitioning from one insurance/payer (such as ADAP medication provision and ADAP-subsidized insurance) to Medicaid. While an overlap might not seem like as big of an issue as a gap, we have heard from insurance assisters that both overlaps and gaps can result in lack of access to medications, including HIV medications. 16 We hypothesize that these overlap and gap issues described by this cohort may be the reason for the lower viral suppression among PWH who transitioned to Medicaid in 2019, which was observed in our clinic's quantitative study. 7 Overlaps/gaps may have only been an issue during the transition year (2019). Future studies will need to see if the overlap/gap issue and lower viral suppression persist for this population.
All participants reported difficulty understanding insurance-related information. Half suggested both more explanation of Medicaid benefits or more/easier access to information in general. Our team's previous research demonstrated PWH who learned about the ACA from websites were more likely to have accurate knowledge about HIV-related aspects of the ACA. 17 Websites may be an avenue to increase information dissemination about aspects of Medicaid that are important for PWH.
Similar to what we have found with previous health care transitions for PWH in Virginia, 4 most participants had assistance in the enrollment process from people such as case managers or social workers. Previous work has demonstrated assisters tailor their approaches to HIV-specific and person-specific concerns by navigating challenges related to affordability, formularies, and provider networks. 16 Almost a quarter stressed the importance of having assistance by including it in their suggestions for Medicaid. The insurance enrollment process can be challenging, especially for patients with limited education or low health literacy. This suggestion highlights the key role of case managers and social workers, who are supported by RWHAP funds or federal navigator funds, as sources of accurate and timely knowledge about the health care delivery system. Recently, there were cuts to the federal insurance navigator funds, 18 but in April 2021, the U.S. Health and Human Services announced $80 million or an eightfold increase in funding for navigators to assist people for the 2022 Open Enrollment period. 19 Assisters' roles will continue to be crucial, especially given the various, complex, and often-changing resources and funding for medical care for PWH. PWH view HIV clinicians as a more trustworthy source of information than their health insurance company, 17 so having clinicians and clinic staff help with insurance transitions could be a facilitator to successful insurance enrollment.
Despite assistance, participants still complained about challenges with the enrollment and re-enrollment process. Other negative experiences highlighted included the following: interruptions in access to care and medications due to re-enrollment problems or changes in insurance providers, unexpected increases in costs for medications or services not sufficiently covered, and missed appointments due to cost concerns and unreliable transportation. Some cost concerns may reflect participants' uncertainty about whether they would be charged cost-sharing or co-pays. Even if their actual costs would have been minimal, their perception of risking a cost could still create a barrier to care with potential negative impact on viral suppression. More transparency around medication and visit costs could help address misperceptions.
Having Medicaid was valuable, but not sufficient to achieving medication adherence, engagement in care, and viral suppression. Difficulties with Medicaid had a negative impact on care for some participants. Others faced difficulties beyond Medicaid itself, including needs related to social determinants of health not fully addressed by insurance coverage. Notably, while this group of PWH has access to RWHAP resources, almost a third had unstable housing, and less than one-third were food secure. Housing and food are two social determinants of health where insurance companies could help bolster resources, in addition to the RWHAP resources. Insurance companies, including Medicaid, should consider ways to address barriers to care, including needs related to social determinants of health.
This study has several limitations. All participants in this study were successfully enrolled in Medicaid in 2019. The benefits and challenges with Medicaid identified by this group may not be generalizable. There could be selection bias with people who opted to participate having more positive experiences with Medicaid. This study recruited from one academic medical center within a single state, so results may not be transferable to other care environments or states that expanded Medicaid in 2014. Future studies in other states would be helpful to determine if this study's findings are unique characteristics to Virginia or are more broadly applicable to the Medicaid for PWH in other states. Other questions to explore further in future work include additional investigation of experiences with overlap/gaps in coverage and the potential role of politicization of health policy in shaping participants' views of Medicaid. In addition, this study was cross-sectional in nature. There is a gap in understanding the longitudinal perspective related to care changes and how participants navigate those changes in real time. This gap highlights the need for future longitudinal perspectives.
Given the recent economic disruption caused by COVID-1920 and the co-location of HIV and COVID-19 in areas with greater poverty and unemployment, 21 –24 Medicaid likely played an important role in 2020 and beyond as a safety net in states with Medicaid Expansion. 25 Our own clinic found rapid unemployment with the start of COVID-19. 6 In a recent national survey, 40% of RWHAP clinicians reported changes in their patients' insurance status/coverage, which they described as an increase in clients who were uninsured, followed by private coverage losses, and then increases in clients with Medicaid. 26 State Medicaid programs may be able to learn from our participants' perspective and suggestions. State ADAPs and RWHAP clinics may also find this information valuable, as they are often helping to navigate insurance status/coverage changes for PWH.
