While 55% of patient charts reflected relatively straightforward PrEP access, we identified four categories of barriers to obtaining PrEP in 45% of the 161 unique patient charts reviewed. In addition to barriers, several patterns in the chart timelines were identified that reveal the impact of barriers and characterize some of the individuals who ultimately do obtain PrEP despite the obstacles.
Site Characteristics
Out of 90 sites selected, 45% were in rural locations, 42% were low prescribers, and 58% were medium or high prescribers. Sites also varied by size of HIV patient population served, ranging from 11 patients to over 700, with 53% of the charts sampled from facilities each serving fewer than 300 HIV-positive patients (see Table 1).
Patient Characteristics
The majority (97%) of the PrEP cohort consisted of male veterans whose primary risk factor for HIV was documented as having male sexual partners. Over half (56%) were identified as white. The qualitative sample of 161 patients had similar demographic characteristics to the total cohort (see Table 3).
Findings
We identified four primary barriers to PrEP prescribing: provider knowledge gaps about PrEP, provider knowledge gaps about PrEP-related VHA systems, provider attitudes about PrEP, and clinic purview barriers (see Table 4). We also identified patterns in the timelines of veterans receiving PrEP: evidence of patients initiating conversations about PrEP and delays in prescribing. Lastly, we identified persistence and PrEP knowledge as two qualities consistently characterizing patients who received PrEP.
Table 4 Barriers to PrEP Access Barriers to PrEP Prescribing
Barriers to PrEP were identified within EHR encounter notes, provider-provider communications, and provider-patient communications. We identified four themes associated with PrEP barriers: provider knowledge gaps about PrEP, provider knowledge gaps about PrEP-related VHA systems, provider attitudes, and clinic purview barriers (see Table 4). Barriers were detected in both urban and rural settings, and irrespective of background HIV prevalence. These barriers were detected within both primary care (PC) and infectious diseases (ID) clinics, sometimes even prior to a clinical encounter in interactions with nurses or with clerks.
Provider knowledge gaps about PrEP were cases in which incorrect information about PrEP was communicated to patients or cases in which provider communications revealed knowledge gaps. Some encounter notes indicated that providers were unaware of PrEP, while others underestimated PrEP’s effectiveness. In two cases, veterans attempted to make an appointment for the purpose of inquiring about PrEP and were told by clerks that such medication did not exist. Other knowledge gaps included incorrect dosing schedules provided to patients, or providers confusing PrEP with post-exposure prophylaxis (PEP). Providers required that patients obtain prescriptions from their partner’s provider or provide documented evidence of their partners’ HIV status, steps not recommended in either VHA or CDC guidelines and place a considerable burden on the patient.
Provider knowledge gaps about PrEP-related VHA systems also created barriers for veterans seeking PrEP. These were cases in which providers were misinformed about VHA policy or other systems related to PrEP. Some providers reported difficulty locating information about the availability of PrEP. Others assumed that VHA was not providing PrEP and advised patients to go elsewhere. Other providers assumed PrEP was not formulary or attempted to determine this by asking the pharmacy.
Provider attitudinal barriers were apparent in documentation of counseling of patients, particularly when paired with a refusal to prescribe PrEP. Some providers focused more on behavioral risk reduction strategies, suggesting limiting or even eliminating sexual activity and discouraging PrEP. In other cases, providers refused to prescribe PrEP to patients who appeared to be good candidates, without documenting a reason. Attitudinal barriers were also apparent in how some providers characterized patients seeking PrEP. One provider stated in a consult: “Veteran unwilling to change behaviors and would like to be evaluated for PrEP.” This contrasts with more neutral encounter notes, for example: “patient reports multiple sexual partners, may be at increased risk for HIV.” Some providers also used the term “admitted” in describing patient behaviors: “patient admits to homosexual behavior.” An “admission” (as opposed to a “report” or “disclosure”) implies culpability or that a behavior is problematic.
Clinic purview barriers were a systems issue identified in cases in which lack of agreement within facilities about the location of care for both PrEP initiation and PrEP maintenance led to delays, multiple visits, and patients being “bounced back and forth between primary care and HIV clinics.” Most veterans initially inquired about PrEP in primary care; however, primary care providers often placed consults to ID clinics. In some cases, referral to ID clinics was upsetting or confusing to HIV-negative veterans. For some, visiting ID clinics or making appointments for PrEP posed privacy concerns.
Patterns in Prescribing
Onus on patients to request PrEP. At least 16% of the veterans who requested PrEP had documented historical evidence of elevated risk for contracting HIV, including being treated for a sexually transmitted infection, being prescribed PEP, requesting multiple HIV tests, or previously disclosing sharing needles or having an HIV-positive partner. Yet despite the prevalence of documented HIV risk, the majority (88%) of patient charts had clear documentation that the patient initiated the PrEP request, while 10 charts (6%) documented provider-initiated PrEP conversations. There were nine charts in which the PrEP initiator could not be identified. In most cases, providers noted that the patient was requesting it: “Homosexual male asking to be put on PrEP kit of Truvada.” In other cases, this was recorded in the referral placed from primary care to ID clinics: “Pt requesting HIV prophylaxis for being homosexual and at high risk for HIV.” Still other times, internal messages to providers from medical assistants, nursing staff, or clerks recorded the patient request: “Patient also stated interest in pre-exposure medications for HIV???? Please advise.”
Patients face refusals and delays. In 35% of cases, barriers resulted in delays in obtaining PrEP prescriptions, with the interval between request and fill ranging from five weeks to 16 months. Reasons associated with delays were not always documented. In response to delays or refusals to prescribe PrEP, some patients made follow-up requests. It is not known what percentage of these requests went undocumented in the EHR but of the 142 veterans who made an initial PrEP inquiry, 23% of them had a second request documented in the EHR at a later medical visit or via the EHR electronic messaging system. Eleven patients (8%) requested PrEP three or more times before obtaining a prescription.
Site Variation
While a full exploration of similarities and differences across low, medium, and high prescribing sites would require additional data not gathered for this study, a few patterns are worth noting. Providers at high prescribing sites tended to exhibit more thorough documentation of safer sex counseling and use less judgmental language in their documentation. They also tended to exhibit fewer knowledge gaps about VHA systems related to PrEP. It was interesting to note however that knowledge gaps about PrEP and attitudinal barriers were identified in all three types of sites. Cases of easeful PrEP access could also be located in low prescribing sites.
Patients Exhibit Knowledge and Persistence
Patients who obtained PrEP tended to enter the clinical encounter already educated about PrEP. Providers documented, for example, “Patient has been reading CDC guidelines,” or “He brought in a journal article.” Providers noted sources of patient PrEP awareness, including media, websites, friends, partners, non-VHA providers, and patients who themselves work in healthcare or public health.
Persistence, the ability and willingness to keep trying even after being turned away, also emerged as a theme characterizing patients in this study. Patients not only made multiple requests but they also made multiple clinic visits, requested appointments even when they were told PrEP was unavailable, utilized different strategies when requesting PrEP, and sought PrEP at VHA after being unable to obtain it elsewhere.
Both persistence and knowledge about PrEP were evident in the secure messages recorded in patients’ EHR. After making a documented three PrEP inquiries spanning 13 months with no apparent follow-up from providers, one veteran wrote:
“Hi Dr., I am following up regarding the inquiry I made last year during my annual check-in about being prescribed Truvada, aka PrEP. What were you able to find out because I think I would be a good candidate for it. I still understand that it is another tool to prevent one from getting HIV and I should still use condoms just as women use birth control pills and men condoms to reduce pregnancies. Last time we spoke you said you would ask the HIV specialist there about it. Could you please let me know what was decided?”
Another patient record indicated she had requested PrEP and had not been informed for several weeks about whether it would be prescribed, despite receiving her negative HIV result:
“I received the test results. I’m aware that they were negative, and I would like to commence taking the medication by the name of Pre-Exposure Prophylaxis (PrEP). My partner was tested and was HIV positive, and that’s why I decided to get tested. My partner and I have discussed taking the proper precautions. He, too, has made the right steps to begin the treatment that he needs. As you know my medical history, I would like if you can consider starting me on PrEP.”
