Key informant views on potential acceptability and feasibility of long-acting antiretroviral treatment for HIV in Kenya.

BACKGROUND: In 2020, 14% of diagnosed persons living with HIV (PLWH) in Kenya were not taking antiretroviral therapy (ART), and 19% of those on ART had unsuppressed viral loads. Long-acting antiretroviral therapy (LA-ART) may increase viral suppression by promoting ART uptake and adherence. We conducted key informant (KI) interviews with HIV experts in Kenya to identify product and delivery attributes related to the acceptability and feasibility of providing LA-ART to PLWH in Kenya. METHODS: Interviews were conducted via Zoom on potential LA-ART options including intra-muscular (IM) injections, subcutaneous (SC) injections, implants, and LA oral pills. KI were asked to discuss the products they were most and least excited about, as well as barriers and facilitators to LA-ART roll-out. In addition, they were asked about potential delivery locations for LA-ART products such as homes, pharmacies, and clinics. Interviews were recorded and transcribed, and data were analyzed using a combination of inductive and deductive coding. RESULTS: Twelve KI (5 women, 7 men) participated between December 2021 and February 2022. Overall, participants reported that LA-ART would be acceptable and preferable to PLWH because of fatigue with daily oral pills. They viewed IM injections and LA oral pills as the most exciting options to ease pill burden and improve adherence. KI felt that populations who could benefit most were adolescents in boarding schools and stigmatized populations such as sex workers. SC injections and implants were less favored, as they would require new training initiatives for patients or healthcare workers on administration. In addition, SC injections would require refrigeration and needle disposal after use. Some KI thought patients, especially men, might worry that IM injections and implants would impact fertility, given their role in family planning. Pharmacies were perceived by most KI as suboptimal delivery locations; however, given ongoing work in Kenya to include pharmacies in antiretroviral delivery, they recommended asking patients their views. CONCLUSION: There is interest and support for LA-ART in Kenya, especially IM injections and LA oral pills. Identifying patient preferences for modes and delivery locations and addressing misconceptions about specific products as they become available will be important before wide-scale implementation.

Patient and Plan Spending after State Specialty-Drug Out-of-Pocket Spending Caps.

BACKGROUND: Specialty drugs are used to treat complex or life-threatening conditions, often at high financial costs to both patients and health plans. Three states - Delaware, Louisiana, and Maryland - passed legislation to cap out-of-pocket payments for specialty drugs at $150 per prescription. A concern is that these caps could shift costs to health plans, increasing insurance premiums. Estimates of the effect of the caps on patient and health-plan spending could inform future policies. METHODS: We analyzed a sample that included 27,161 persons under 65 years of age who had rheumatoid arthritis, multiple sclerosis, hepatitis C, psoriasis, psoriatic arthritis, Crohn's disease, or ulcerative colitis and who were in commercial health plans from 2011 through 2016 that were administered by three large nationwide insurers. The primary outcome was the change in out-of-pocket spending among specialty-drug users who were in the 95th percentile for spending on specialty drugs. Other outcomes were changes in mean out-of-pocket and health-plan spending for specialty drugs, nonspecialty drugs, and nondrug health care and utilization of specialty drugs. We compared outcomes in the three states that enacted caps with neighboring control states that did not, 3 years before and up to 3 years after enactment of the spending cap. RESULTS: Caps were associated with an adjusted change in out-of-pocket costs of -$351 (95% confidence interval, -554 to -148) per specialty-drug user per month, representing a 32% reduction in spending, among users in the 95th percentile of spending on specialty drugs. This finding was supported by multiple sensitivity analyses. Caps were not associated with changes in other outcomes. CONCLUSIONS: Caps for spending on specialty drugs were associated with substantial reductions in spending on specialty drugs among patients with the highest out-of-pocket costs, without detectable increases in health-plan spending, a proxy for future insurance premiums.

Assessing Payers' Preferences for Real-World Evidence in the United States: A Discrete Choice Experiment.

OBJECTIVES: To rank the US payers' preferences for attributes of real-world evidence (RWE) studies in the context of chronic disease and to quantify trade-offs among them. METHODS: We conducted a discrete choice experiment in which 180 employees from payer organizations were tasked to choose between 2 RWE studies assuming they were assessing evidence to inform formulary decisions for chronic disease treatment. Each RWE study was characterized by 7 attributes with 3 levels each: very informative, moderately informative, and not measured. We used a D-optimal main-effects design. Survey data were fitted to a conditional logit model to obtain a relative measure of the ranking of importance for each attribute. RESULTS: Clinical outcomes were the most preferred attribute. It was 4.68 times as important as productivity outcomes-the least preferred attribute. It was followed by health-related quality of life (2.78), methodologic rigor (2.09), resource utilization (1.71), and external validity (1.56). CONCLUSIONS: This study provides a quantification of the value payers place on key RWE attributes. Across attributes, payers have higher preferences for clinical and health-related quality of life outcomes than the other attributes. Between attributes' levels, payers prefer high levels of information in clinical outcomes and methodologic rigor but are indifferent in other attributes. Our results bridge the gap between the information that payers seek and the attributes that RWE studies prioritize and effectively guide future research design.

The systematic development of attributes and levels for a discrete choice experiment of HIV patient preferences for long-acting antiretroviral therapies in the United States.

INTRODUCTION: Patient preferences for long-acting antiretroviral therapies (LA-ART) should inform development of regimens with optimal adherence and acceptability. We describe a systematic process used to identify attributes and levels for a discrete choice experiment (DCE) designed to elicit preferences for potential LA-ART options in the US. METHODS: Our approach was conducted in four stages: data collection, data reduction, removing inappropriate attributes, and optimizing wording. We started with 8 attributes defining potential LA-ART products based on existing literature and knowledge of products in development. We conducted 12 key informant interviews with experts in HIV treatment. The list of attributes, the set of plausible levels for each attribute, and restrictions on combinations of attribute levels were updated iteratively. RESULTS: Despite uncertainty about which products will become available, key informant discussions converged on 4 delivery modes (infusions and patches were not considered immediately feasible) and 6 additional attributes. Treatment effectiveness and frequency of clinical monitoring were dropped. Oral lead-in therapy was split into two attributes: pre-treatment time undetectable and pre-treatment negative reaction testing. We omitted product-specific systemic and local side effects. In addition to mode, the final set of attributes included: frequency of dosing; location of treatment; pain; pre-treatment time undetectable; pre-treatment negative reaction testing; and late-dose leeway. CONCLUSIONS: A systematic process successfully captured elements that are both feasible and relevant to evaluating the acceptability of potential LA-ART alternatives to patients.

Association between having a family member with dementia and perceptions of dementia preventability.

BACKGROUND: One's experience with dementia may affect their perceptions about dementia preventability, which in turn could influence preventive health behaviors. We aimed to examine how having a family history of dementia and caregiving experience are associated with perceptions about and self-efficacy for dementia preventability. METHODS: Cross-sectional, self-administered survey. Participants reported whether they have had a family member with dementia and, among those who reported having a family member with dementia, whether they served as a caregiver. Outcomes were perceptions about the likelihood of dementia preventability, self-efficacy for dementia prevention, and benefits of specific dementia prevention strategies. Associations were assessed via partial proportional odds model for ordinal outcome variables and logistic regression for binary outcome variables. RESULTS: Of 1,575 respondents, 71% had a family member with dementia, of which 42% served as a caregiver. People with a family member with dementia were less likely to believe that dementia is preventable (aOR = 0.75, 95% CI: 0.58, 0.96) and had lower self-efficacy for dementia prevention (aOR = 0.71, 95% CI: 0.56, 0.90). The subgroup analysis among those with caregiving experience was consistent with the primary findings, showing less belief in the likelihood of dementia preventability (aOR = 0.69, 95% CI: 0.46, 1.03) and self-efficacy (aOR = 0.75, 95% CI: 0.56, 1.00). CONCLUSION: Having a family member with dementia is associated with unfavorable perceptions about dementia preventability. Incorporating family history of dementia into communication efforts about dementia risk reduction may help address potential barriers to preventive health behaviors.

Difficulty with Taking Medications Is Associated with Future Diagnosis of Alzheimer's Disease and Related Dementias.

BACKGROUND: Medication management requires complex cognitive functioning, and therefore, difficulty taking medications might be an early sign of cognitive impairment and could be a risk factor for Alzheimer's disease and related dementias (ADRD). Accordingly, people with difficulty taking medications may benefit from more detailed cognitive screening, potentially aiding in the diagnosis of ADRD, which is underdiagnosed. We are unaware of evidence on medication management difficulties that precede a real-world ADRD diagnosis in the USA. OBJECTIVE: Examine the association between difficulty taking medications and subsequent real-world ADRD diagnoses. DESIGN: Case-control study, using Health and Retirement Study (HRS) survey data linked to Medicare claims. PARTICIPANTS: A total of 1461 HRS respondents with an ADRD diagnosis observed from 1993 to 2012 (cases), matched by year of birth, wave of HRS entry, and sex to 3771 controls with no ADRD diagnosis. MAIN MEASURES: We examined the association between diagnosis of ADRD and self-reported difficulty taking medications in the preceding years (1-2 and 3-4 years prior to case definition). Control individuals were assigned the index date from their matched case. Conditional logistic regressions adjusted for age, sex, race, education, and comorbidities. KEY RESULTS: Compared with matched controls, cases had higher prevalence of difficulty taking medications 1-2 years prior to diagnosis (11.0% versus 2.3%), and 3-4 years prior to diagnosis (5.8% versus 2.3%). Adjusted analyses showed that compared with individuals without ADRD, those with an ADRD diagnosis had more than four times higher odds of difficulty taking medications 1-2 years prior (OR = 4.56 (CI 3.30-6.31)), and more than two times higher odds of difficulty taking medications 3-4 years prior (OR = 2.41 (CI 1.61-3.59)). CONCLUSIONS: Odds of medication difficulty 1-2 years prior were more than four times greater for individuals with ADRD diagnoses compared with those without ADRD. Medication management difficulties may prompt further cognitive screening, potentially aiding in earlier recognition of ADRD.

Geographic variation in the use of triptans and opioids for the acute treatment of migraine attacks.

OBJECTIVE: To assess the geographic variations in triptan and opioid prescribing patterns for patients with migraine. BACKGROUND: Numerous guidelines recommend triptans as the standard of care for migraine attacks, yet opioids are still widely used for migraine treatment. Variation in the use of opioids and triptans for the treatment of migraine by geographic location is not well known. METHODS: Using a US claims database, we conducted a retrospective cohort study of adults diagnosed with migraine between 2016 and 2018. We used a 12-month follow-up period to assess triptan and opioid utilization, stratified by the nine Census Bureau-designated divisions. To examine the geographic factors that affect triptan and opioid use among patients, we conducted two sets of multivariable analyses. First, we analyzed the odds of a patient being a triptan or opioid user in the follow-up period, defined as ≥1 triptan or opioid claim. We then analyzed the medication use rate among triptan or opioid users. RESULTS: Overall, we had a final study population of 113,921 patients. In the follow-up period, 52.9% (60,247/113,921) [range: 48.0%-56.3%] of patients were triptan users and 41.0% (46,708/113,921) [range: 28.9%-48.4%] of patients were opioid users with significant differences across census divisions (p < 0.001). Triptan users had a mean (SD) of 4.8 (4.7) triptan claims annually with no significant differences across divisions (p = 0.188). Opioid users had a mean (SD) of 5.4 (6.8) opioid claims annually with significant differences across divisions (p < 0.001). The observed variation in opioid use stemmed from the proportion of patients using opioids in each region and not from the number of opioid prescriptions per user. CONCLUSIONS: There was a significant geographic variation in the use of opioids and to a lesser degree the use of triptans. The widespread use of opioids and the large variation in use other than triptans as the standard of care suggest that improvements could be made in the acute treatment of migraine attacks.

Drug therapies for chronic conditions and risk of Alzheimer's disease and related dementias: A scoping review.

INTRODUCTION: Most older Americans use drug therapies for chronic conditions. Several are associated with risk of Alzheimer's disease and related dementias (ADRD). METHODS: A scoping review was used to identify drug classes associated with increasing or decreasing ADRD risk. We analyzed size, type, and findings of the evidence. RESULTS: We identified 29 drug classes across 11 therapeutic areas, and 404 human studies. Most common were studies on drugs for hypertension (93) or hyperlipidemia (81). Fewer than five studies were identified for several anti-diabetic and anti-inflammatory drugs. Evidence was observational only for beta blockers, proton pump inhibitors, benzodiazepines, and disease-modifying anti-rheumatic drugs. For 13 drug classes, 50% or more of the studies reported consistent direction of effect on risk of ADRD. DISCUSSION: Future research targeting drug classes with limited/non-robust evidence, examining sex, racial heterogeneity, and separating classes by molecule, will facilitate understanding of associated risk, and inform clinical and policy efforts to alleviate the growing impact of ADRD.

Alzheimer's disease and related dementias risk: Comparing users of non-selective and M3-selective bladder antimuscarinic drugs.

PURPOSE: Bladder antimuscarinic (BAM) drug use is associated with increased risk of Alzheimer's disease and related dementias (ADRD). It is hypothesized that BAMs with non-selective receptor binding may increase ADRD risk more than M3-selective BAMs. This study compared ADRD risk for users of non-selective and M3-selective BAMs and examines ADRD risk associated with overall BAM use. METHODS: Retrospective cohort study of Medicare claims for 71 688 individuals who used BAM drugs during 2007-2009 without an ADRD diagnosis. We compared ADRD incidence (2011-2016) between non-selective BAM users (fesoterodine, flavoxate, oxybutynin, tolterodine, trospium) and M3-selective BAM users (darifenacin, solifenacin). Logistic regressions compared individuals using target drugs in the same category of total standardized daily doses (TSDD) as a standardized measure of drug exposure, and adjusted for age, sex, race/ethnicity, healthcare utilization, other medication use, socioeconomic status, and comorbidities. Secondary analyses compared ADRD risk associated with different doses of BAMs overall. RESULTS: Non-selective BAM use (compared to M3-selective) was not significantly associated with ADRD incidence. Odds ratios for non-selective use were 0.97 (CI: 0.89-1.04) for 1-364 TSDD, 0.94 (CI: 0.83-1.06) for 365-729, 1.00 (CI: 0.87-1.16) for 730-1094, and 1.03 (CI: 0.88-1.20) for >1094. Higher TSDD of BAMs overall (combining both non-selective and M3-selective BAMs), when compared to 1-364 TSDD, were associated with increased ADRD incidence (OR = 1.05 (CI: 0.99-1.10) for 365-729, OR = 1.11 (CI: 1.05-1.17) for 730-1094, and OR = 1.10 (CI: 1.04-1.15) for >1094). CONCLUSIONS: Non-selective and M3-selective BAM users had similar odds of ADRD incidence, and BAM use overall was significantly associated with ADRD incidence.

Longitudinal analysis of dementia diagnosis and specialty care among racially diverse Medicare beneficiaries.

INTRODUCTION: There is insufficient understanding of diagnosis of etiologic dementia subtypes and contact with specialized dementia care among older Americans. METHODS: We quantified dementia diagnoses and subsequent health care over five years by etiologic subtype and physician specialty among Medicare beneficiaries with incident dementia diagnosis in 2008/09 (226,604 persons/714,015 person-years). RESULTS: Eighty-five percent of people were diagnosed by a nondementia specialist physician. Use of dementia specialists within one year (22%) and five years (36%) of diagnosis was low. "Unspecified" dementia diagnosis was common, higher among those diagnosed by nondementia specialists (33.2%) than dementia specialists (21.6%). Half of diagnoses were Alzheimer's disease. DISCUSSION: Ascertainment of etiologic dementia subtype may inform hereditary risk and facilitate financial and care planning. Use of dementia specialty care was low, particularly for Hispanics and Asians, and associated with more detection of etiological subtype. Dementia-related professional development for nonspecialists is urgent given their central role in dementia diagnosis and care.

The effects of state-level pharmacist regulations on generic substitution of prescription drugs.

Substituting generic for brand name drugs whenever possible has been proposed to control prescription drug expenditure growth in the United States. This work investigates two types of state laws that regulate the procedures under which pharmacists substitute bioequivalent generic versions of brand name drugs. Mandatory substitution laws require pharmacists to use the generic as a default, and presumed consent laws allow them to assume that the patient agrees to the substitution. Both situations can be overruled by the patient. Using plausibly exogenous changes in states' laws, we use difference-in-differences and a discrete choice model to show that although the mandatory switching laws have little effect, the presumed consent laws reduce consumers' probability of purchasing brand name drugs by 3.2% points. The differential effectiveness of the laws is likely caused by pharmacists' profit motives. These results offer important implications for policies that seek to reduce drug expenditures by incentivizing the use of generic drugs.

Analyzing whether countries are equally efficient at improving longevity for men and women.

OBJECTIVES: We examined the efficiency of country-specific health care spending in improving life expectancies for men and women. METHODS: We estimated efficiencies of health care spending for 27 Organisation for Economic Co-operation and Development (OECD) countries during the period 1991 to 2007 using multivariable regression models, including country fixed-effects and controlling for time-varying levels of national social expenditures, economic development, and health behaviors. RESULTS: Findings indicated robust differences in health-spending efficiency. A 1% annual increase in health expenditures was associated with percent changes in life expectancy ranging from 0.020 in the United States (95% confidence interval [CI] = 0.008, 0.032) to 0.121 in Germany (95% CI = 0.099, 0.143). Health-spending increases were associated with greater life expectancy improvements for men than for women in nearly every OECD country. CONCLUSIONS: This is the first study to our knowledge to estimate the effect of country-specific health expenditures on life expectancies of men and women. Future work understanding the determinants of these differences has the potential to improve the overall efficiency and equity of national health systems.

Medicare expenditures among spouses of persons with dementia.

BACKGROUND: Spouses of persons living with dementia face intense strains on their well-being compared with similarly aged adults and spouses of partners with no dementia. This strain can impact spouses' health and healthcare needs, and therefore affect their healthcare utilization and expenditures. METHODS: Using data from the Health and Retirement Study linked with Medicare claims, we matched dyads of spouses and their partners with dementia (SPWD) to a comparison group of similar spouses and their partners with no dementia (SPWND). We then examined Medicare expenditures for spouses in the 5 years following their partner's dementia onset month using a two-part regression model. RESULTS: SPWD cumulative total Medicare expenditures were, on average, $60,043 in the 5 years post dementia onset, compared to $56,068 for SPWND. This difference ($3974, 95% CI = [-$3,199; $11,477]) was not significant. However, there were significant differences in the 5th year's total expenditures (+$2,748 [$321; $5,447]), driven by inpatient expenditures ($1,562 [$22; $3,277]). CONCLUSIONS: Despite the differences in partner's dementia status, we found no significant difference in the 5-year cumulative Medicare expenditures between SPWD and SPWND. Compared to previous studies, we likely captured an earlier stage of dementia more consistently for a broader population which may be less straining on spouses. Further research should examine patterns of expenditures in later years and around critical timepoints in caregiving, such as partner transitions to formal long-term care settings and death, to better understand healthcare expenditures for spouses of persons living with dementia.

Caregiving for dementia: trends pre-post onset and predictive factors of family caregiving (2002-2018).

Persons living with Alzheimer's and other related forms of dementia rely heavily on care from family and friends for assistance with daily activities ("family care"), but little is known about care transitions over time. We analyzed data from the Health and Retirement Study to describe caregiving patterns, from 2 years before dementia onset and up to 6 years after. Using sociodemographic data from the interview prior to dementia onset, we determined if there are significant factors that predict receipt of family care at dementia onset. We found that one-third (33%) of people living with dementia were receiving help with daily activities 2 years prior to their first positive dementia screen and this increased to 60% during the first positive screen. Nearly all of those receiving assistance received family care. We found multiple significant predictors of receiving family care at onset, including race, education, access to private health insurance, number of activities of daily living that were difficult, number of chronic conditions, and already receiving help. This demonstrates potential gaps in dementia care, and which subpopulations may benefit most from targeted interventions for household members who do not have adequate caregiving resources or programs that provide additional formal care.

Health care resource utilization and costs among patients with multiple myeloma with exposure to double-class or triple-class multiple myeloma treatments: A retrospective US claims database analysis.

BACKGROUND: Despite recent advancements in the therapeutic landscape, multiple myeloma (MM) remains incurable. There are multiple treatment options available with a novel mechanism of action, but there is limited evidence describing the economic burden among patients with MM exposed to different drug classes and combinations and across different health care settings. OBJECTIVE: To describe all-cause and MM-related health care resource utilization (HCRU) and costs among patients with MM exposed to different drug classes and combinations (ie, double-class and triple-class-exposed) and characterize the economic burden in different health care settings among these patients with MM. METHODS: We conducted a retrospective cohort study using the IBM MarketScan databases. The study included adult patients (aged ≥18 years) diagnosed with MM between December 1, 2015, and December 31, 2019. The study sample comprised double-class-exposed (DCE) and triple-class-exposed (TCE) cohorts, categorized based on their earliest exposure to different combinations of immunomodulatory drugs, proteasome inhibitors, or targeted monoclonal antibody. Patients with at least 1 subsequent line of therapy following the categorization were included, and the start date of the first subsequent line of therapy was the index date. The primary outcomes were all-cause and MM-related HCRU and costs during the follow-up period. Costs were stratified across 8 care settings defined by place of service. The Kaplan-Meier sample average technique was used to estimate the cumulative mean outcomes, accounting for differential follow-up periods. The outcomes were reported as per patient per month (PPPM). 18 years) diagnosed with MM between December 1, 2015, and December 31, 2019. The study sample comprised double-class-exposed (DCE) and triple-class-exposed (TCE) cohorts, categorized based on their earliest exposure to different combinations of immunomodulatory drugs, proteasome inhibitors, or targeted monoclonal antibody. Patients with at least 1 subsequent line of therapy following the categorization were included, and the start date of the first subsequent line of therapy was the index date. The primary outcomes were all-cause and MM-related HCRU and costs during the follow-up period. Costs were stratified across 8 care settings defined by place of service. The Kaplan-Meier sample average technique was used to estimate the cumulative mean outcomes, accounting for differential follow-up periods. The outcomes were reported as per patient per month (PPPM). RESULTS: The study included 1,521 patients with MM, of whom 1,016 (66.8%) were DCE and 505 (33.2%) were TCE. The mean total all-cause health care costs were $20,338 PPPM, and approximately 85% of the total all-cause costs were MM-related. The mean all-cause and MM-related total costs were driven by overall drug costs primarily attributed to MM treatment and administration costs. The TCE cohort was associated with more HCRU and incurred higher costs than the DCE cohort across all categories. The hospital-based ambulatory setting had the highest all-cause and MM-related costs during the follow-up period: $7,302 (95% CI = $6,801-$7,784) PPPM and $6,695 (95% CI = $6,239-$7,136) PPPM, respectively. CONCLUSIONS: The study findings suggest that the economic burden following exposure to multiple drug classes and combinations is substantial, especially among the TCE cohort and in the ambulatory setting. These findings highlight the need for more effective treatments that can mitigate the economic burden of patients with MM. Future research on the HCRU and costs related to recently approved MM treatments with novel mechanisms is warranted.

U.S. patient preferences for long-acting HIV treatment: a discrete choice experiment.

INTRODUCTION: Recent advances in long-acting antiretroviral therapy (LA-ART) could provide new options for HIV treatment and reduce adherence barriers, if regimens are acceptable to patients. We elicited preferences for key attributes of potential LA-ART regimens among people with HIV (PWH) in the United States, focusing on four treatment modes (oral tablets, subcutaneous injections, intramuscular injections, and implants), product characteristics and location of administration. METHODS: A discrete choice experiment was conducted among PWH aged ≥18 years recruited from HIV clinics in Washington State and Atlanta, Georgia from March 2021 to June 2022. Participants responded to 17 choice scenarios, each with three options: two systematically generated hypothetical LA-ART regimens and a constant opt-out (their current daily oral treatment). LA-ART regimen descriptions included treatment mode, pain, dosing frequency, location, pre-treatment time with undetectable viral load, pre-treatment negative reaction testing and "late-dose leeway" (i.e. flexibility or forgiveness in timing the next dose). We used conditional logistic regression, with an interaction between treatment mode and pain, to estimate preference weights for all attribute levels. RESULTS: Seven hundred participants (350 at each site) enrolled, with median age 51 years (range 18-73); 70% identified as cisgender male, 24% as cisgender female and 6% as non-binary or transgender. LA oral tablets were the only mode preferred over current daily oral treatment, with annual implants and injections the next most preferred LA-ART option. Longer time between doses was preferred, and administration at home was preferred to clinics, which were preferred to pharmacies. Attributes with less impact on preferences included oral lead-in treatment to achieve viral suppression or test for negative reactions and late-dose leeway around the prescribed dosing interval. Participants in Atlanta were more likely to prefer their current daily oral ART than participants from Seattle. CONCLUSIONS: PWH in the United States may soon have several options for LA-ART. Our results suggest that LA oral tablets will be preferred by many patients over their current daily oral treatment, while implants and injections with longer duration may be acceptable to some. Future research should investigate sources of preference heterogeneity and actual uptake of and adherence to LA-ART products, when available.

Preference for daily oral pills over long-acting antiretroviral therapy options among people with HIV.

OBJECTIVE: To examine the characteristics of people with HIV (PWH) who prefer remaining on daily oral antiretroviral therapy (ART), rather than switching to long-acting ART (LA-ART). DESIGN: Building upon a discrete choice experiment (DCE), we examined characteristics of individuals who always selected their current daily oral tablet regimen over either of two hypothetical LA-ART options presented in a series of 17 choice tasks. METHODS: We used LASSO to select sociodemographic, HIV-related, and other health-related predictors of preferring current therapy over LA-ART, and logistic regression to measure the associations with those characteristics. RESULTS: Among 700 PWH in Washington State and Atlanta, Georgia, 11% of participants ( n  = 74) chose their current daily treatment over LA-ART in all DCE choice tasks. We found that people with lower educational attainment, good adherence, more aversion to injections, and who participated from Atlanta to be more likely to prefer their current daily regimen over LA-ART. CONCLUSIONS: Gaps in ART uptake and adherence remain, and emerging LA-ART treatments show promise to address these challenges and help a larger portion of PWH to achieve viral suppression, but preferences for these new treatments are understudied. Our results show that certain drawbacks of LA-ART may help to maintain demand for daily oral tablets, especially for PWH with certain characteristics. Some of these characteristics (lower educational attainment and Atlanta participation) were also associated with a lack of viral suppression. Future research should focus on overcoming barriers that impact preferences for LA-ART among those patients who could benefit most from this innovation.

Opportunity after crisis: enhancing value in the COVID-19 rebound.

As we reset post pandemic, providers and payers are in an excellent position to prioritize a reallocation of health care expenditures driven primarily by individual and population health gains.

Improvements to Survey Design from Pilot Testing a Discrete-Choice Experiment of the Preferences of Persons Living with HIV for Long-Acting Antiretroviral Therapies.

BACKGROUND AND OBJECTIVE: Development of clear and effective discrete-choice experiment surveys is an important step toward ensuring accurate and usable preference results. Pretest interviews and pilot testing are common in the development of discrete-choice experiments, and it is important for researchers to report details of survey changes resulting from patient feedback elicited in pilot work. This paper details pilot testing of an online discrete-choice experiment to elicit preferences for long-acting antiretroviral therapies among patients with HIV. METHODS: The survey included an introduction to hypothetical treatment options, descriptions of attributes, comprehension questions, instructions for completing a discrete-choice experiment, a discrete-choice experiment with 17 choice tasks, and questions about personal characteristics. We piloted the survey with 50 respondents over ten waves. Each wave incorporated design improvements based on observations made during the previous wave. Respondents completed the online survey while screen sharing with a researcher, allowing interactive discussion. We developed a scheme for assessing and categorizing the survey changes. RESULTS: Changes to the pilot were categorized by ways they impacted aspects of the discrete-choice experiment or the likely quality of resulting data. The four categories of impact are: understanding of attributes, underlying discrete-choice experiment and understanding of the choice question, collection of individual characteristics hypothesized to affect preference, and changes that improved clarity and usability of the survey without directly affecting the other categories (e.g., survey navigation and instructional clarity, formatting changes). CONCLUSIONS: Detailed attention to the respondent experience in this large pilot allowed survey improvements that will likely reduce ambiguity, ensure more accurate capture of patient preferences and, ultimately, improve product development for long-acting antiretroviral therapies.

Association Between Informant-Reported Sleep Disturbance and Incident Dementia: An Analysis of the National Alzheimer's Coordinating Center Uniform Data Set.

Informants' reports can be useful in screening patients for future risk of dementia. We aimed to determine whether informant-reported sleep disturbance is associated with incident dementia, whether this association varies by baseline cognitive level and whether the severity of informant-reported sleep disturbance is associated with incident dementia among those with sleep disturbance. A longitudinal retrospective cohort study was conducted using the uniform data set collected by the National Alzheimer's Coordinating Center. Older adults without dementia at baseline living with informants were included in analysis. Cox proportional hazards models showed that participants with an informant-reported sleep disturbance were more likely to develop dementia, although this association may be specific for older adults with normal cognition. In addition, older adults with more severe sleep disturbance had a higher risk of incident dementia than those with mild sleep disturbance. Informant-reported information on sleep quality may be useful for prompting cognitive screening.
