INTRODUCTION
Antiretroviral treatment (ART) can improve health outcomes among people living with HIV (PLHIV) and prevent onward HIV transmission1,2, yet, holistic patient care goes beyond medications. For PLHIV to thrive, not only survive, other components of HIV care need to be present3, including a non-judgmental and supportive clinical environment, peer support and counseling, well-coordinated care across disciplines; and quality communication with their healthcare providers (HCPs). High-value care that is both effective and efficient lies at the intersection of the best scientific evidence, the provider’s clinical expertise, and the patient’s preferences (i.e. evidence-based medicine)4,5.
Separating the perceived unmet needs of PLHIV between those that relate to broader HIV management issues versus those relating specifically to their HIV medication can help identify specific areas to improve the HIV care cascade. These overlapping, yet distinct, facets of patient care can influence each other in complex ways. For example, negative perceptions regarding quality of overall care received may sabotage adherence6. At the same time, medicationrelated challenges could also complicate overall treatment and adherence7-9. Other barriers to adherence include inconvenient dosing schedules, stigma, medication-related privacy concerns, emotional challenges, and polypharmacy (drug-drug interactions)10-13. There is therefore compelling need for flexible ART options that will meet the diversity of unmet medical, psychosocial, and emotional needs among PLHIV. Determining perceived gaps in care, as well as which treatment considerations are most important to patients with specific unmet needs can better help in tailoring treatment.
Currently there is no cure for HIV but there is plenty of research to suggest means for a functional cure may be available soon14,15. For example, long-acting cabotegravir and rilpivirine (CAB LA + RPV LA) is an innovative HIV treatment regimen that provides PLHIV with a long-acting treatment alternative that is as effective as daily oral ART14,15. This novel treatment, which eliminates the need for adherence to daily dosing, has significant potential to mitigate the substantial clinical and humanistic burden associated with daily oral ART. Administered parenterally, the new treatment may be beneficial to PLHIV with conditions that make oral administration of ART challenging (e.g. dysphagia, gastroesophageal reflux disease, and malabsorption), and for those at risk of drug-drug and drug-food interactions.
As the worldview in relation to patient care shifts from conquering diseases to promoting health and wellbeing16,17, and as PLHIV live longer18-20, treatment innovations that address the wide spectrum of patient unmet needs can help meet the fourth ‘90’ target of improving quality of life among PLHIV17. Promising treatment innovations provide an anchor for patients’ aspirations and may incentivize adherence to current treatment. Absent such advances in drug research and development, PLHIV may aspire for better treatment, yet feel nothing can be done, and therefore spiral into despair, nonadherence, and disengagement. However, knowing more is being done to develop treatment alternatives can provide hope and help PLHIV cope with their current treatment challenges. More so, discussing their treatment aspirations can build trust between patients and their providers and help in developing an ideal treatment plan to address identified concerns. PLHIV who are aware of ongoing advances in the field and their potential to positively impact patient care may also be more likely to participate in, and help improve the generalizability of clinical studies, which often underrepresent women and non-white ethnic groups21-23.
With the major strides in drug development, it is important to assess treatment aspirations among PLHIV, separate from their current treatment satisfaction, as these are distinct perceptions. To capture treatment aspirations among PLHIV in 25 countries during 2019, this study had the following objectives: 1) assess dissonance in perceived satisfaction with overall HIV management versus HIV medications; 2) identify what PLHIV consider as the ‘most important improvements’ to HIV medicines; and 3) explore factors associated with preference for innovative treatments.
METHODS
Study population/sampling approach
We conducted a web-based survey of 2389 PLHIV on ART, distributed in the following countries: USA (400), South Africa (179), Russia (150), United Kingdom (123), Australia (120), Canada (120), France (120), Germany (120), Italy (120), Spain (120), Japan (75), Mexico (63), Portugal (60), Brazil (58), Switzerland (55), Taiwan (55), Netherlands (51), Argentina (50), Austria (50), Chile (50), China (50), Ireland (50), Belgium (50), Poland (50), and South Korea (50). We recruited participants from existing panels of confirmed HIV seropositive individuals, as well as from support groups/communities and online platforms. To better understand perceptions and attitudes of key population subgroups, sampling was purposive and aimed at achieving adequate sample sizes within three pre-specified strata: those diagnosed as HIV seropositive within the last two years, women, and persons aged ≥50 years. Single IRB review for the multi-site study was done by the Pearl Institutional Review Board (no. 18–080622). In addition, specific approval for South Africa was obtained from the Sefako Makgatho Research Ethics Committee (no. SMUREC/M/223/2019). Participants provided written informed consent.
Questionnaire development and fielding
Development of the study instrument was done with input from PLHIV and an advisory panel of HIV physicians. Questionnaires were reviewed by local teams to ensure they were culturally and contextually appropriate. The survey instrument was pre-tested to ensure comprehension, flow, and online usability. The survey was administered in 20 languages: English, Canadian French, Latin American Spanish, Brazilian Portuguese, French, German, Italian, Spanish, Portuguese, Dutch, Flemish, Polish, Russian, Afrikaans, Zulu, Sotho, Japanese, Korean, Traditional Chinese, and Simplified Chinese. Translation of the English version of the screener and questionnaire to relevant local language(s) in each country was performed by medically trained translators through an iterative process to ensure accuracy. Once in the target language, additional trained translators proofread the questionnaire prior to final approval by local partners.
Data collection was done electronically using a web-based questionnaire that was self-completed by the respondent. The online questionnaire was rendered for ease of completion on all device types (mobile, tablet and laptop/desktop) and major operating systems (IOS, Android); average completion time was 30 minutes. In a few instances where the respondent could not complete the survey unaided (e.g. because of limited literacy, language barrier, or lack of internet access), their answers were entered by a facilitator asking the questions directly to the respondent or entered by the respondent but with a facilitator on-hand to assist in case of any difficulty. Only in South Africa was this assisted mode of data collection used to a significant extent (29%; 52/179 of South African participants).
Measures
PLHIV treatment experiences and challenges
Participants who rated their health as ‘Good’/‘Very good’ were classified as having ‘optimal’ health (vs ‘Neither good nor poor’/ ‘Poor’/ ‘Very poor’). Polypharmacy was defined as taking ≥5 pills/day for HIV and non-HIV conditions combined, or currently taking medicines for ≥5 medical conditions, including HIV. Data were also collected on formulation of ART medications (single or multiple tablets), difficulty swallowing pills, treatment-related privacy concerns (hiding/disguising HIV medications within the past 6 months), frequency of missed ART doses in past month, and outlook towards dying prematurely from HIV. Poor self-prognosis regarding HIV mortality was an affirmative response (‘Agree’ or ‘Strongly agree’) to either statement below: ‘HIV will reduce my life span’ or ‘Because of my HIV, I do not plan for my old age’. Participants were classified as experiencing side effects from their current HIV medication if they answered ‘Agree’ or ‘Strongly’ agree to the statement: ‘My current HIV medication gives me side effects’. Presence of ‘gastrointestinal side effects (stomach upset, stomachache/pain, diarrhea)’, was further assessed among those reporting any side effects. Suboptimal adherence was defined as a report of ≥1 reason for missing ART ≥5 times within the past month.
Perceived satisfaction with HIV medications and overall management
Patient perception towards treatment is multidimensional; PLHIV may like certain aspects of their treatment (i.e. extent to which it meets their current needs), but not others (i.e. perceived gaps). We created separate derived variables indicating presence or absence of ‘full’ satisfaction with HIV medication and with HIV overall management, respectively. To achieve greater specificity in the definitions, each measure of ‘full’ satisfaction was derived from two variables measuring perceived satisfaction and perceived gaps. We classified PLHIV as perceiving they were fully satisfied with their HIV medication if they reported high levels of satisfaction with their ‘current HIV medication’ (‘satisfied’ or ‘very satisfied’) and at the same time did not strongly perceive that ‘there is room for improvement with [their] current HIV medication’ (scores of ≤3 on a 1–5 ordinal scale); otherwise, they were classified as having some level of dissatisfaction with their current HIV medication. Likewise, PLHIV were classified as being fully satisfied with their overall HIV management if they reported high levels of satisfaction with ‘the management of [their] HIV treatment’ in relation to whether it met their personal needs/things most important to them (scores of ≥4 on a 1–5 ordinal scale) and at the same time did not strongly perceive that ‘I feel there is room for improving the way my HIV is managed’ (scores of ≤3 on a 1–5 ordinal scale); otherwise, they were classified as having some level of dissatisfaction with their overall HIV management. Using these two derived measures, we created a composite variable that assessed whether needs are fully met for management, needs are fully met for medication, and their interaction. With this composite variable, participants were classified as being fully satisfied with: 1) neither their broader HIV management nor their medication; 2) their HIV medication only; 3) their broader HIV management only; and 4) both their broader HIV management and medication.The survey also assessed various aspects of patient-provider communication and information sharing. Participants were further asked: ‘When you first started HIV treatment, other than ensuring that it was effective, what were your most important considerations?’. Multiple responses could be selected.
Perception of ‘most important’ and ‘least important’ improvements to HIV medicines
We used an experimental design within the survey, known as Maximum Diffusion (MaxDiff), to evaluate which of the following seven potential improvements to HIV medicines was perceived to be most desirable to PLHIV: ‘Smaller pills’; ‘Fewer side effects’; ‘Reduced long-term impact on my body’; ‘Less chance of affecting other medicines/drugs/pills I take’; ‘No food restrictions or requirements’; ‘Less HIV medicine each day but just as effective’; and ‘Longer-lasting medicine so I don’t have to take it every day (e.g. a monthly injection administered by a doctor/nurse)’.
The research question we were exploring was: ‘what is the order of patients’ ranking of preferences or perceived importance for these seven treatment attributes?’. In the MaxDiff experiment, nine consecutive blocks (screens) were displayed, each block featuring three attributes selected at random. Participants rated which of the three attributes was, in their opinion, the ‘Most important improvement’, and which was the ‘Least important’. A total of 2158 respondents completed the experiment; no significant differences were seen between these individuals versus the 231 participants who did not complete the experiment, in relation to key demographics including age, gender, and sexual orientation.
Treatment aspirations
The belief that ‘future advances in HIV treatment will improve my overall health and wellbeing’ was based on a response of ‘Agree’ or ‘Strongly agree’ (vs ‘Neither agree nor disagree’, ‘Disagree’, or ‘Strongly disagree’).
Besides assessing perceived importance of certain treatment attributes, the survey also measured participants’ openness towards using novel HIV medications with some of those attributes, including ART with fewer medicines as well as long-acting regimen14,15. Openness towards long-acting regimens was defined as a response of ‘Agree’ or ‘Strongly agree’ to the statement: ‘As long as my HIV stays suppressed, I would prefer not having to take HIV medication every day’. These two perceptions were not mutually exclusive. We previously reported the percentage of PLHIV open to HIV treatments composed of fewer medicines in preliminary analyses of our data from 24 countries.24 Here we provide an update of that estimate based on the full sample of 25 countries, along with additional multivariable analyses.
Analyses
The full sample size of 2389 was used for all analyses, except for the MaxDiff experiment which was completed by 2158 participants. Prevalence estimates for indicators of interest were calculated and compared with chi-squared tests. We used multivariable logistic regression analyses to explore factors associated with discordant perceptions regarding satisfaction with overall HIV management versus HIV medication, assessing for age, ethnicity, education, region, duration of disease, and gender. Exploratory logistic regression analyses were also performed among all participants to assess factors associated with openness towards taking an HIV medication with fewer medicines or a long-acting regimen.
To analyze the MaxDiff experiment, we generated variables for each possible allocation – a total of 63 new variables (9 blocks × 7 attributes)25,26. For each of these 63 generated variables, possible codes assigned were: 0 (attribute shown but not selected); 1 (attribute ranked as ‘Most important’); -1 (attribute ranked as ‘Least important’); or missing (attribute not shown). To account for differential frequency of appearance of the different attributes, we created attribute-specific weights by dividing the number of times each attribute was selected by the number of times it appeared. We computed the weighted probabilities that each individual attribute was ranked in the 1st, 2nd, …7th position; to minimize ties, very small, randomly generated numbers were added to each observation. Across all attributes, we also computed the ‘preference shares’ for the 1st through 7th position or rank. The issue of which rank should be more relevant is determined purposefully, not statistically; here, we present the aggregate percentage of those who ranked each attribute in the first or second position as a measure of overall appeal. All analyses were performed with R v3.4.1. Statistical significance was set at p<0.05.
RESULTS
Of the 2389 study participants, 41.2% were heterosexual, 45.8% were homosexual, while 13.0% identified as ‘other sexual orientation’. By gender, 67.9% identified as men, 29.1% as women, and 2.9% as ‘other gender’ (Table 1). Of all study participants, 21.8% (520/2389) were from the USA/Canada, 46.8% (1119/2389) from Europe, 9.2% (221/2389) from Latin America, 9.6% (230/2389) from Asia, 5.0% (120/2389) from Australia, and 7.5% (179/2389) from South Africa.

Dissonance in satisfaction with HIV management vs medications
Important treatment considerations at time of ART initiation among all participants included: ‘to ensure side effects would be minimal’, 53.8% (1285/2389); ‘to manage symptoms or illnesses caused by HIV’, 51.6% (1232/2389); ‘to ensure that the virus was suppressed enough so that I could not pass it on to a partner’, 49.1% (1173/2389); ‘to minimize the long-term impact of HIV treatment’, 43.4% (1037/2389); ‘to allow flexibility as to when I have to take the HIV medication (time of day, with or without food, etc.)’, 35.4% (846/2389); ‘to keep the number of HIV medicines in my treatment to a minimum’, 34.8% (832/2389); ‘that the treatment is available in my public health facility’, 31.0% (741/2389); that the HIV medication ‘was compatible with other medications/drugs/pills I was taking’, 30.8% (737/2389); ‘cost of the medication’, 24.5% (585/2389); and having ‘the best option to allow me to have children’, 16.8% (402/2389). Subgroup differences are shown in Table 1.
At the time of the survey, only 17.5% (417/2389) of all participants reported being fully satisfied with both their overall HIV management and medication: 26.8% (639/2389) were fully satisfied with only their HIV medication, 9.8% (235/2389) with only their overall HIV management, and 46.0% (1098/2389) with neither (Figure 1). Compared to those fully satisfied with neither their HIV medication nor overall management, those fully satisfied with both had higher prevalence of optimal adherence to treatment (89.2% [372/417] vs 69.5% [763/1098]), optimal overall health (70.3% [293/417] vs 47.8% [525/1098]), and a positive outlook for their HIV survival (67.6% [282/417] vs 38.3% [420/1098]) (all p<0.001) (Figure 2). Among those fully satisfied with their HIV medication, 60.5% (639/1056) reported some level of dissatisfaction with their overall HIV management, while 36.0% (235/652) of those fully satisfied with their overall HIV management reported some level of dissatisfaction with their HIV medication.
Factors associated with reporting some level of dissatisfaction with HIV medication among those otherwise fully satisfied with their overall HIV management included being on a multi-tablet regimen (AOR=2.76; 95% CI: 1.93– 3.96), reporting polypharmacy (AOR=2.10; 95% CI: 1.45–3.03), and experiencing ART side effects (AOR=2.12; 95% CI: 1.49–3.02) (Supplementary file, Figure S1). In contrast, the odds of reporting some level of dissatisfaction with HIV medication among those otherwise fully satisfied with their overall HIV management were lower among those who felt they understood enough about their treatment (AOR=0.41; 95% CI: 0.27–0.62), and those who indicated that their HCP provided them with enough information to be involved in making decisions (AOR=0.45; 95% CI: 0.31–0.67), sought their view before prescribing treatment (AOR=0.59; 95% CI: 0.41–0.86), inquired whether they had any treatment concerns (AOR=0.65; 95% CI: 0.45–0.94), frequently asked if they were experiencing side effects (AOR=0.51; 95% CI: 0.35–0.73), or told them the benefits of being virally undetectable (i.e. Undetectable = Untransmittable; AOR=0.38; 95% CI: 0.26–0.55). Individuals with optimal self-rated health in the various domains assessed, were also less likely to report some level of dissatisfaction with their HIV medication among those otherwise fully satisfied with their overall HIV management. Among those otherwise fully satisfied with their HIV medication, perception of some level of dissatisfaction with their broader HIV management was associated with poor patient–provider communication and experience of side effects as shown in Supplementary file, Figure S1.
Perceived appeal of various potential improvements to HIV medicines
Of the seven potential improvements to HIV medicines evaluated within the MaxDiff experiment, the percentage of PLHIV who ranked each attribute as either the first or second most important was: ‘reduced long-term impact on my body’ (46.7%); ‘longer-lasting medicine so I don’t have to take it every day’ (43.1%); ‘fewer side effects’ (40.5%); ‘less HIV medicine each day but just as effective’ (25.4%); less chance of affecting other medicines/drugs/pills I take’ (21.6%); ‘no food restrictions or requirements’ (14.0%); and ‘smaller pills’ (8.7%) (Figure 3).
In terms of individual ranks, the attributes with the largest preference shares for the top (i.e. first) position were ‘longerlasting medicine so I don’t have to take it every day’ (25.9%), followed by ‘reduced long-term impact on my body’ (23.3%) and ‘fewer side effects’ (19.6%). For the second position, the largest preference shares were for ‘reduced long-term impact on my body’ (23.4%), ‘fewer side effects’ (20.9%), and ‘longer-lasting medicine so I don’t have to take it every day’ (17.2%). For the third position, the largest preference shares were for ‘reduced long-term impact on my body’ (19.2%), ‘less HIV medicine each day but just as effective’ (18.5%), and ‘fewer side effects’ (18.1%).
Treatment aspirations
Overall, 77.1% (1842/2389) of all participants believed that ‘future advances in HIV care will improve [their] overall health and wellbeing’. This aspiration was highest among those who were fully satisfied with their HIV medication only (85.3%, 545/639) and lowest among those fully satisfied with their overall HIV management only (68.1%, 160/235); the two groups at the extremes – those fully satisfied with both, or with neither – reported prevalence of 78.7% (328/417) and 73.7% (809/1098), respectively (p=0.046). Those fully satisfied with neither their medication nor management differed significantly in this aspiration when compared with those fully satisfied with their medication only (p<0.001) but did not differ significantly from those fully satisfied with their overall HIV management only (p=0.081).
Of all participants, 72.2% (1726/2389) were ‘open to taking an HIV treatment composed of fewer medicines’, and 54.7% (1306/2389) indicated preference for a long-acting regimen; country-specific estimates are given in Figure 4. Medication-related privacy concerns were not significantly associated with openness to taking an HIV treatment with fewer medicines but were associated with preference for a long-acting regimen (Table 2); those who ever hid/disguised their HIV medicines had 28% higher odds of preferring a long-acting regimen (AOR=1.28; 95% CI: 1.06–1.55). With increases in the maximum number of times ART was missed for any given reason in the past month, odds of being open to taking an HIV treatment with fewer medicines decreased (AOR=0.69 and 0.56, for 2–4 and ≥5 times of missed dose, respectively, all p<0.05). Conversely, those missing ART for up to 2–4 and ≥5 times within the past month for any reason had 29% and 38% higher odds of preferring a long-acting regimen, respectively, compared to those with no missed dose (all p<0.05). Those who had ever changed their ART ≥2 times had higher odds of being open to an HIV treatment with fewer medicines (AOR=1.72; 95% CI: 1.31–2.26) and also preferring a long-acting regimen (AOR=1.33; 95% CI: 1.04–1.70). Compared to those who never wanted a different HIV medication than the one they were currently on, those who ever wanted one in the past but were not prescribed after discussing with their HCP were more likely to be open to an HIV treatment with fewer medicines (AOR=1.45; 95% CI: 1.05–2.00), as well as preferring a longer-acting regimen (AOR=1.47; 95% CI: 1.12–1.91). Those fully satisfied with their HIV medication had lower odds of preferring a longacting regimen (AOR=0.74; 95% CI: 0.60–0.91), but reported higher odds of being open to taking an HIV treatment with fewer medicines (AOR=1.28; 95% CI: 1.01–1.63). PLHIV who lived in a non-metropolitan area had lower odds than those in a metropolitan area of being open to taking an HIV treatment with fewer medicines (AOR=0.75; 95% CI: 0.61–0.91) or preferring a long-acting regimen (AOR=0.78; 95% CI: 0.65–0.93). Compared to newly diagnosed PLHIV (2017-2019), odds of preferring a long-acting regimen were significantly lower among those diagnosed during 2010–16 (AOR=0.70; 95% CI: 0.55–0.88) and pre-2010 (AOR=0.69; 95% CI: 0.52–0.91). Compared to PLHIV in Northern America, those in Australia had 86% higher odds of being open to an HIV treatment with fewer medicines (AOR=1.86; 95% CI: 1.05–3.27) while those in South Africa had 59% lower odds of indicating preference for longer-acting regimens (AOR=0.41; 95% CI: 0.27–0.62). Having ≥2 comorbidities was positively associated with 31% higher odds of preferring a long-acting regimen, compared to not having any comorbidity (AOR=1.31; 95% CI: 1.05–1.63, Table 2).

Countries by region were: Northern America (U.S. and Canada); Europe (Austria, Belgium, France, Germany, Italy, the Netherlands, Poland, Portugal, Ireland, Russia, Spain, Switzerland, and the UK); Latin America (Argentina, Brazil, Chile, and Mexico), Asia (China, Japan, South Korea, and Taiwan).
DISCUSSION
Less than 1 in 5 (17.5%) of PLHIV were fully satisfied with both their overall HIV management and medications, whereas over 4 in 5 perceived gaps in either their overall HIV management or their medication. Among those otherwise fully satisfied with their overall HIV management, over 1 in 3 (36%) reported some level of dissatisfaction with their HIV medication, especially those experiencing side effects, with polypharmacy, and on multi-tablet ART regimens. On the other hand, among those fully satisfied with their HIV medication, factors like polypharmacy, tablet formulation, or self-rated health status, were not found to be significantly associated with perceived gaps in overall HIV management. The top three treatment attributes perceived as most important were medicines with reduced long-term adverse impact, longer-lasting medicine that eliminated the need for daily intake, and those with fewer side effects.
Enhanced and sustained efforts to improve quality of life among PLHIV must involve holistic care as our results showed that 3 in 5 (60.5%) PLHIV who were fully satisfied with their medication still perceived gaps in their overall HIV management. Notably, the highest percentage of those believing that future advances in HIV treatment will improve their overall wellbeing was seen among PLHIV reporting full satisfaction with their HIV medication only, underscoring the impact of HIV treatment on quality of life, even among those with the most favorable perceived treatment experiences currently. Addressing patients’ preferences and concerns is key to meeting the fourth ‘90’ target, ensuring that PLHIV not only survive, but thrive16,17. Besides ensuring patient convenience, improved quality of life can mitigate treatment failure by tackling the chief causes of non-adherence27, including emotional challenges and psychosocial barriers.
The success of treatment goals may depend on perceived facilitators and impediments at the level of the patient (e.g. lifestyle factors), the disease (e.g. chronicity), treatment of the disease (e.g. side effects), and patient relationship with healthcare providers (e.g. perceived involvement in care)28. In our study, preferences were varied, as were individual circumstances. Study participants who had some unmet needs or constraints with their current treatment (e.g. privacy concerns, poor adherence, and polypharmacy), were all more likely to prefer a long-acting injectable regimen. Several studies have shown a relationship between treatment satisfaction and adherence to daily oral ART, suggesting that providing PLHIV and HCPs with treatment options they value may help further increase treatment adherence, retention in care, and quality of life of PLHIV29-32. Providing flexible treatment options can help patients across the spectrum of unique medical and non-medical needs, to optimize healthrelated outcomes. Our observation of improved indicators of quality of life among those fully satisfied with both their medication and their overall care makes intensified efforts towards holistic HIV care paramount.
Strengths and limitations
This study’s strengths include the collection of information from a large sample of participants from 25 countries using a standardized instrument. It is important to note that this population is not the general population but, rather, is a population of confirmed HIV seropositive individuals, which is a significant strength of the study. In evaluating treatment preferences of PLHIV, we used an experimental technique (Maximum Diffusion) for more robust preference identification under possible inconsistent choice behavior. Some limitations however exist. First, the online fielding of the survey could have limited participation for those with computer literacy and internet access. Second, these data are cross-sectional in nature and only associations can be drawn. Third, participants were selected non-probabilistically, which may limit study generalizability. Selection of eligible countries was also driven by logistical considerations not purely by burden of disease. Despite these limitations, these study findings draw attention to the need for holistic HIV care to improve health outcomes among PLHIV.
CONCLUSIONS
Overall, only 17.5% were fully satisfied with both their overall HIV management and HIV medication. Furthermore, 72.2% were open to taking an HIV treatment with fewer medicines, and 54.7% preferred a long-acting regimen. Preference for a long-acting injectable regimen was higher among those with comorbidities, with suboptimal adherence, and those experiencing ART side effects. The top three treatment improvements perceived as most important were HIV medicines with reduced long-term adverse impact, longer-lasting medicines that eliminated the need for daily intake, and those with fewer side effects. Providing flexible treatment options can help patients across the spectrum of unique medical needs and preferences to improve their health-related quality of life.
