ABSTRACT

Background: Cabotegravir (CAB) + rilpivirine (RPV) dosed monthly or every 2 months is a complete long-acting (LA) regimen for the maintenance of human immunodeficiency virus type 1 virologic suppression. Across the phase 3/3b trials, the most frequently reported adverse events were injection site reactions (ISRs). Methods: We present pooled ISR characteristics and outcomes for participants receiving CAB + RPV LA through week 96 of the FLAIR and ATLAS-2M studies, and survey results from healthcare providers (HCPs) giving injections (eg, injectors) in the ATLAS, FLAIR, and ATLAS-2M studies to determine optimal injection techniques. Surveys were anonymous, self-administered online questionnaires that queried provider demographics, injection experience, and techniques to minimize pre-/postinjection discomfort. Data were summarized using descriptive statistics. Results: Overall, 8453 ISRs were reported by 801 participants receiving ≥1 injection of CAB LA/RPV LA. Most ISRs were mild to moderate in severity (grade 1-2, 99%), with a median duration of 3 days (interquartile range, 2-4 days), and rarely led to withdrawal (2%). Surveys were completed by 181 HCPs across 113 sites. Pushing the intramuscular injection at slow speed (66%), bringing the medication to room temperature (58%), and relaxing the gluteus muscle before injecting (53%) were ranked as effective preinjection/injection procedure practices for minimizing pain. Most injectors (60%) indicated that a prone position provided optimal patient comfort, and 41% had no preference on injection medication order. Conclusions: Taken together, the data demonstrate favorable tolerability with CAB + RPV LA injections over the long term and simple techniques routinely used by injectors to help optimize the administration of CAB + RPV LA injections.

ABSTRACT

INTRODUCTION: The CUSTOMIZE hybrid III implementation-effectiveness study evaluated implementation of once-monthly long-acting (LA) cabotegravir + rilpivirine in diverse US healthcare settings. Here, we report patient participant perspectives after 12 months in CUSTOMIZE. METHODS: CUSTOMIZE was a phase IIIb, 12-month study conducted from July 2019 to October 2020 at eight diverse US HIV clinics that enrolled virologically suppressed people living with HIV-1 (PLHIV) on a stable oral regimen to receive monthly cabotegravir + rilpivirine LA injections after a 1-month oral lead-in. Participants were administered quantitative surveys before injections at months 1 (baseline), 4 and 12. A randomly selected subset of participants was interviewed at baseline and month 12. Data collection at month 12 was completed by October 2020 (during the COVID-19 pandemic). RESULTS: At baseline, 109 and 34 participants completed surveys and interviews, respectively; 87% were male; 35% were Black or African American. All participants who remained in the study at month 12 (n = 102) maintained HIV-1 RNA <50 copies/ml; two participants withdrew due to injection-related reasons. Mean total scores measuring acceptability and appropriateness of cabotegravir + rilpivirine LA were high at baseline (4.5-4.6 out of 5) and month 12 (4.7-4.9). At month 12, 74% of participants reported nothing interfered with receiving LA injections; injection pain or soreness was the most common concern (15%). Time spent in the clinic and coming to the clinic for monthly injections was very or extremely acceptable after 12 months for most participants (93% and 87%, respectively), with 64% reporting having spent ≤30 minutes in the clinic for injection visits. At month 12, 92% of participants preferred LA injections to daily oral tablets (3%); 97% plan to continue LA treatment going forward. In month 12 interviews, 24 (77%) of 31 participants reported the COVID-19 pandemic did not impact their ability to receive treatment. CONCLUSIONS: Once-monthly cabotegravir + rilpivirine LA was highly acceptable among PLHIV who were virologically suppressed on a stable antiretroviral regimen and interested in trying LA therapy, with few participants reporting challenges receiving LA injections. Implementation data from CUSTOMIZE suggest that monthly LA injections provide a convenient and appealing treatment option for PLHIV.

ABSTRACT

INTRODUCTION: CUSTOMIZE evaluated the implementation of long-acting (LA) cabotegravir + rilpivirine, a novel healthcare provider-administered injectable antiretroviral therapy regimen, in diverse US healthcare settings. Findings from staff-study participants (SSPs) through 12 months of implementation are reported. METHODS: CUSTOMIZE was a phase IIIb, 12-month, single-arm, hybrid III implementation-effectiveness study conducted from July 2019 to October 2020 at eight US clinics of five clinic types: private practice (n = 2), federally qualified health centre (n = 2), university (n = 2), AIDS Healthcare Foundation (n = 2) and health maintenance organization (n = 1). Eligible patient participants received monthly cabotegravir + rilpivirine LA injections after a 1-month oral lead-in. At baseline, month 4 and month 12, SSPs (n = 3 each per clinic), including physicians, nurses or injectors, and administrators, completed quantitative surveys and semi-structured interviews to assess implementation outcomes (acceptability, appropriateness and feasibility of intervention measures), programme sustainability and SSP perceptions of, attitudes towards, and expectations for cabotegravir + rilpivirine LA. Month 12 data collection occurred during the COVID-19 pandemic. RESULTS: In surveys, SSPs reported high mean total scores for acceptability, appropriateness and feasibility of cabotegravir + rilpivirine LA implementation at baseline (4.43, 4.52 and 4.38 of 5, respectively) and month 12 (4.45, 4.61 and 4.46 of 5, respectively), regardless of clinic type. At month 12, SSPs were positive about the implementation sustainability (mean Program Sustainability Assessment Tool score, 5.83 out of 7). At baseline, SSPs' top concern was patients' ability to maintain monthly appointments (81%); at month 12, 39% had this concern. The proportion of SSPs reporting patient injection pain or soreness as a barrier was consistent at month 12 versus baseline (48% vs. 46%). Most (78%) SSPs reported optimal implementation of cabotegravir + rilpivirine LA in their clinics was achieved in 1-3 months. In interviews, SSP-reported strategies for successful implementation included teamwork, using a web-based treatment planner and having a designated person to track appointment scheduling. In month 12 interviews, SSP-reported structural changes needed for implementation included changing clinic hours and purchasing refrigerators. CONCLUSIONS: In CUSTOMIZE, cabotegravir + rilpivirine LA was successfully implemented across a range of US healthcare settings. Barriers were mitigated with minor process adjustments.

ABSTRACT

A long-acting injectable (LAI) antiretroviral therapy (ART) regimen is now available as a treatment option for virologically suppressed adults with HIV-1. This study assessed preference for a LAI regimen using an online survey of virally suppressed people living with HIV (PLWH) and physicians treating HIV in the US and Canada. Preference was elicited in a discrete choice experiment (DCE) with three choice options (switch to a LAI regimen, switch to another daily oral ART regimen, or stay on their current daily oral ART regimen) and four treatment attributes. A total of 553 PLWH and 450 physicians completed the survey. From the DCE results, 59% of PLWH were predicted to prefer a LAI over an alternative oral ART or staying on their current oral treatment, and 55-66% of physicians were predicted to recommend LAI for PLWH, depending on the treatment challenge scenario presented. PLWH indicated LAI would remove daily reminders of HIV (75%) and reduce feelings of being stigmatized (68%). A majority of PLWH and physicians preferred a LAI over oral ART to overcome treatment challenges such as daily pill burden and adherence. These benefits of LAI ART along with preferences of PLWH and physicians can help to inform ART choice.

ABSTRACT

OBJECTIVES: Long-acting formulations of cabotegravir (CAB) and rilpivirine (RPV) have demonstrated efficacy in Phase 3 studies. POLAR (NCT03639311) assessed antiviral activity and safety of CAB+RPV long-acting administered every 2 months (Q2M) in adults living with HIV-1 who previously received daily oral CAB+RPV in LATTE (NCT01641809). DESIGN: A Phase 2b, multicenter, open-label, rollover study. METHODS: LATTE participants with plasma HIV-1 RNA less than 50 copies/ml who completed at least 300 weeks on study were eligible. Participants elected to switch to either CAB+RPV long-acting Q2M or daily oral dolutegravir/RPV for maintenance of virologic suppression. The primary endpoint was the proportion of participants with HIV-1 RNA greater than or equal to 50 copies/ml at Month 12 (M12) per the Food and Drug Administration Snapshot algorithm. The incidence of confirmed virologic failure (CVF, two consecutive HIV-1 RNA measurements greater than or equal to 200 copies/ml), as well as safety, laboratory, and patient-reported outcomes (HIV Treatment Satisfaction and preference questionnaires) were also assessed. RESULTS: Of 97 participants enrolled, 90 chose to receive CAB+RPV long-acting and seven chose dolutegravir/RPV. At M12, no participant had HIV-1 RNA greater than or equal to 50 copies/ml or met the CVF criterion in either treatment group. No new safety signals were identified. Total treatment satisfaction was high at Baseline and remained stable through M12 across both treatment groups. Overall, 88% (n = 77/88) of long-acting arm participants preferred CAB+RPV long-acting to oral CAB+RPV. CONCLUSION: CAB+RPV long-acting maintained virologic suppression in participants who had previously received daily oral CAB+RPV for at least 5 years in LATTE, with a favorable safety profile. Most participants preferred CAB+RPV long-acting to their prior oral CAB+RPV regimen at M12.

ABSTRACT

AIMS: Single-tablet regimens (STRs) can improve antiretroviral therapy (ART) adherence; however, the relationship between long-term adherence and patient healthcare resource utilization (HRU) is unclear. The objective of this study was to assess long-term ART adherence among people living with HIV (PLHIV) using STRs and multi-tablet regimens (MTRs) and compare HRU over time by adherence. MATERIALS AND METHODS: This retrospective study analyzed medical and pharmacy claims (Optum Clinformatics Data Mart Database). Included PLHIV were aged ≥18 years, had ≥1 medical claim with an HIV diagnosis, and had pharmacy claims for a complete STR or MTR. Adherence was analyzed as the proportion of days covered (PDC), stratified as ≥95%, very high; 90-95%, high; 80-90%, moderate; <80%, low. Cumulative all-cause and HIV-related HRU were calculated across 4 years. Among PLHIV with ≥4-year follow-up, HRU was assessed by adherence. RESULTS: Among 15,153 PLHIV included, 63% achieved PDC ≥90% during Year 1. Among the subgroup of PLHIV with ≥4-year follow-up (N = 3,818), the proportion maintaining PDC ≥90% fell from 67% in Year 1 to 54% by Year 4. The difference from Years 1 to 4 in the proportion of PLHIV with PDC ≥90% was 13% and 17% in the STR and MTR groups, respectively. Cumulative HRU across the 4-year follow-up was higher in PLHIV with low vs high adherence (27% with low adherence had ≥1 emergency room visit vs 17% for very high, p < .0001; 15% with low adherence had ≥1 inpatient stay vs 7% for very high, p < .0001). CONCLUSIONS: ART adherence showed room for improvement, particularly over the long term. PLHIV receiving STRs exhibited higher adherence vs those receiving MTRs; this difference increased over time. The proportion of PLHIV with higher HRU was significantly higher among those with lower adherence and became greater over time. Interventions and alternative therapies to improve adherence among PLHIV should be explored.

ABSTRACT

Long-acting injectable antiretroviral therapy has been shown to be non-inferior to daily oral antiretroviral therapy in clinical trials and may soon become part of clinical care. While most trial participants to date have been men, approximately one quarter of ongoing Phase 3 trial participants are women offering an important opportunity to understand how long-acting antiretroviral therapy is perceived and experienced by women. We conducted in-depth interviews with 80 people living with HIV participating in Phase 2 and 3 clinical trials of long-acting antiretroviral therapy in the USA and Spain. Fifteen percent (12/80) of trial participants interviewed were women. Interviews were audio-recorded, transcribed and coded using content analysis, focused on gender-specific themes. Women shared many of the positive perceptions expressed by men but also had unique perspectives, including finding that long-acting antiretroviral therapy addressed the challenge of remembering pills amidst busy day-to-day realities including multiple roles and responsibilities, is less time consuming and creates less stress compared to oral antiretroviral therapy, and is emotionally freeing and empowering. The gendered nature of women's lives shaped why and how they were satisfied with long-acting antiretroviral therapy. Findings can inform interventions and support systems to facilitate uptake of and adherence to long-acting antiretroviral therapy in women.

ABSTRACT

OBJECTIVE: Historically, a high burden of resistance to antiretroviral therapy (ART) in heavily treatment-experienced (HTE) persons with HIV (PWH) resulted in limited treatment options (LTOs). We evaluated the prevalence, risk factors, and virologic control of HTE PWH with LTO throughout the modern ART era. DESIGN: We examined all ART-experienced PWH in care between 2000 and 2017 in the Centers for AIDS Research Network of Integrated Clinical Systems cohort. METHODS: We computed the annual prevalence of HTE PWH with LTO defined as having two or less available classes with two or less active drugs per class based on genotypic data and cumulative antiretroviral resistance. We used multivariable Cox proportional hazards models to examine risk of LTO by 3-year study entry periods adjusting for demographic and clinical characteristics. RESULTS: Among 27 133 ART-experienced PWH, 916 were classified as having LTO. The prevalence of PWH with LTO was 5.2-7.5% in 2000-2006, decreased to 1.8% in 2007, and remained less than 1% after 2012. Persons entering the study in 2009-2011 had an 80% lower risk of LTO compared with those entering in 2006-2008 (adjusted hazard ratio 0.20; 95% confidence interval: 0.09-0.42). We found a significant increase in undetectable HIV viral loads among PWH ever classified as having LTO from less than 30% in 2001 to more than 80% in 2011, comparable with persons who never had LTO. CONCLUSION: Results of this large multicenter study show a dramatic decline in the prevalence of PWH with LTO to less than 1% with the availability of more potent drugs and a marked increase in virologic suppression in the current ART era.

ABSTRACT

BACKGROUND: Dolutegravir-based 2-drug regimens (DTG 2DRs) are now accepted as alternatives to 3-drug regimens for HIV antiretroviral treatment (ART); however, literature on physician drivers for prescribing DTG 2DR is sparse. This study evaluated treatment patterns of DTG 2DR components in clinical practice in the US. METHODS: This was a retrospective chart review in adult patients in care in the US with HIV-1 who received DTG 2DR prior to July 31, 2017, with follow-up until January 30, 2018. Primary objectives of the study were to determine reasons for patients initiating DTG 2DR and to describe the demographics and clinical characteristics. All analyses were descriptive. RESULTS: Overall, 278 patients received DTG 2DR (male: 70%; mean age: 56 years). Most patients were treatment experienced (98%), with a mean 13.5 years of prior ART. DTG was most commonly paired with darunavir (55%) or rilpivirine (27%). The most common physician-reported reasons for initiating DTG 2DR were treatment simplification/streamlining (30%) and avoidance of potential long-term toxicities (20%). Before starting DTG 2DR, 42% of patients were virologically suppressed; of those, 95% maintained suppression while on DTG 2DR. Of the 50% of patients with detectable viral load before DTG 2DR, 79% achieved and maintained virologic suppression on DTG 2DR during follow-up. There were no virologic data for 8% of patients prior to starting DTG 2DR. Only 15 patients discontinued DTG 2DR, of whom 4 (27%) discontinued due to virologic failure. CONCLUSIONS: Prior to commercial availability of the single-tablet 2DRs, DTG 2DR components were primarily used in treatment-experienced patients for treatment simplification and avoidance of long-term toxicities. Many of these patients achieved and maintained virologic suppression, with low discontinuation rates.

ABSTRACT

BACKGROUND: HIV is a condition that requires lifelong treatment. Treatment options currently consist of oral antiretroviral therapies (ART) taken once or twice daily. Long-acting injectable HIV treatments are currently in development to be administered monthly or every other month. Preferences for route of administration could influence treatment adherence, which could affect treatment outcomes. The purpose of this study was to examine patient perceptions of oral and injectable routes of administration for ART. METHODS: Qualitative thematic analysis was conducted to examine 5122 online discussion threads by people living with HIV (PLHIV) in the POZ Community Forums from January 2013 to June 2018. Analysis focused on identifying perceptions of oral or injectable routes of administration for ART. Relevant threads were extracted and imported into the qualitative data analysis software package ATLAS.ti.8 so that text could be reviewed and coded. RESULTS: Analyses identified 684 relevant discussion threads including 2626 coded quotations from online posts by 568 PLHIV. The oral route of administration was discussed more frequently than injectable (2516 quotations for oral; 110 injectable). Positive statements on the oral route of administration commonly mentioned the small number of pills (276 quotations), dose frequency (245), ease of scheduling (153), and ease of use (146). PLHIV also noted disadvantages of the oral route of administration including negative emotional impact (166), difficulty with medication access (106), scheduling (131), and treatment adherence (121). Among the smaller number of PLHIV discussing injectable ART, common positive comments focused on dose frequency (34), emotional benefits of not taking a daily pill (7), potential benefits for adherence (6), overall convenience (6), and benefits for traveling (6). Some comments from PLHIV perceived the frequency of injections negatively (10), and others had negative perceptions of needles (8) or appointments required to receive injections (7). CONCLUSIONS: Qualitative analysis revealed that route of administration was frequently discussed among PLHIV on this online forum. While many expressed positive views about their daily oral medication regimen, others perceived inconveniences and challenges. Among PLHIV who were aware of a possible monthly injectable treatment, many viewed this new route of administration as a convenient alternative with potential to improve adherence.

ABSTRACT

INTRODUCTION: Dolutegravir (DTG), Elvitegravir (EVG), Raltegravir (RAL) and Darunavir (DRV) are commonly prescribed core agents for antiretroviral therapy (ART), and a need exists to compare their clinical effectiveness, as defined by virologic failure risks in real-world settings. METHODS: This observational analysis of a US clinical cohort consisted of ART-naïve people living with HIV (PLWH) in the OPERA database initiating DTG-, EVG-, RAL- or DRV-based regimens between August 2013 and July 2016, with follow-up to July 2017. PLWH were observed from first core agent initiation until core agent discontinuation, clinical activity cessation, death, or study end. Key outcomes included viral suppression (HIV RNA < 50 copies/mL) and confirmed virologic failure (two consecutive viral loads > 200 copies/mL or a viral load > 200 copies/mL followed by discontinuation). Association between core agent and time to virologic failure was assessed with multivariate Cox proportional hazards models. RESULTS: Overall, 4049 ART-naïve PLWH initiated EVG (47.4%), DTG (34.7%), DRV (14.6%), or RAL (3.2%). DTG and EVG initiators had generally similar baseline demographics and clinical characteristics, including race, risk of infection, baseline viral load, and baseline CD4 levels. RAL and DRV initiators were older and generally sicker than DTG initiators. During follow-up, more DTG initiators achieved virologic suppression (78.7%) compared with EVG (73.6%; p < 0.05), RAL (51.9%; p < 0.0001) and DRV (48.6%; p < 0.0001) initiators. Compared to DTG, both RAL and DRV were associated with higher rates of virologic failure, with adjusted hazard ratios (95% confidence interval) of 4.70 (3.03, 7.30) and 2.38 (1.72, 3.29), respectively. No difference was observed between EVG and DTG with an adjusted hazard ratio of 1.24 (0.94, 1.64). CONCLUSION: In this large cohort representative of PLWH in care in the US, ART-naïve PLWH prescribed DTG had better virologic outcomes than RAL and DRV, but had virologic failure risks comparable to EVG, although RAL and DRV were preferentially prescribed to sicker individuals.

ABSTRACT

OBJECTIVE: To evaluate the reliability, validity, responsiveness, and utility of the Lupus Impact Tracker (LIT). METHODS: This was a prospective longitudinal study with 20 North American sites participating. Consenting patients completed the LIT, Medical Outcomes Study Short Form 36 (version 2), Patient Health Questionnaire 9 (PHQ-9), LupusQoL, and patient LIT feedback questionnaire. Rheumatologists completed the Safety of Estrogens in Lupus Erythematosus National Assessment (SELENA) version of the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI), Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index, and physician LIT feedback questionnaire. The reliability, convergent validity, construct validity, and responsiveness of the LIT were evaluated. RESULTS: Of the 325 SLE patients enrolled, 90% were female, 53% were white, and 33% were African American. Their mean age was 42 years. The mean ± SD baseline physician's global assessment and total SELENA-SLEDAI scores were 1.04 ± 0.8 and 4.28 ± 3.8, respectively, while 3-month scores were 0.94 ± 0.73 and 4.09 ± 3.79, respectively. Internal consistency reliability was high (>0.9) at both visits. LIT scores correlated highly with other measures of patient-reported outcomes, and construct validity was established against clinical measures. The LIT was highly responsive to patient-reported changes in SLE health status; however, LIT scores were not as responsive to changes in the SELENA-SLEDAI score. The majority of patients and physicians found LIT to be acceptable and feasible to administer in a clinical setting. CONCLUSION: The LIT is a reliable and valid instrument for assessing the impact of SLE on patients and captures unique and important information not included in physician assessments of disease. It may be useful in clinical practice to facilitate communication between the physician and the patient and enable efficient incorporation of the patient's perspective in disease management.

ABSTRACT

BACKGROUND: Systemic lupus erythematosus (SLE) is a chronic autoimmune disorder which can affect multiple organs of the body, requiring ongoing disease management and healthcare resource utilization. The economic impact of SLE has not been evaluated in a Medicare population to date. This study was conducted to assess the prevalence of SLE and its burden in terms of healthcare resource utilization and costs in a US Medicare population. METHODS: This was a retrospective observational study using Medicare medical claims data (5% random sample) for the period spanning 2003 to 2007. SLE patients were identified by having ≥2 medical claims with a primary or secondary diagnosis of ICD-9 code 710.0X. The earliest quarter of SLE diagnosis was defined as the index quarter. Prevalence of SLE, the proportion of SLE cases on disability benefits, and the contribution of SLE to new disability cases were evaluated. Healthcare resource utilization and direct medical costs (2008 US dollars) over 12 months were compared between a cohort of patients with SLE and a cohort without SLE matched on key demographics. Differences in outcomes between cohorts were assessed using McNemar's test for dichotomous variables and paired t-tests for continuous variables. RESULTS: A total of 13,348 patients with SLE were identified. The prevalence of SLE was approximately 3 per 1000 Medicare beneficiaries. After matching, the sample consisted of 6,707 SLE and 13,414 non-SLE patients. On average, the SLE cohort compared with the non-SLE cohort had 2.4 times more physician visits, 2.7 times more hospitalizations, 2.2 times more outpatient visits, and 2.1 times more emergency room visits. A medical cost surplus of approximately $10,229 per patient per year in the SLE cohort relative to the non-SLE cohort was driven largely by inpatient hospitalization costs (p < 0.001). CONCLUSIONS: SLE prevalence was 3 per 1,000 Medicare patients. Patients with SLE consumed significantly more health care resources with significantly greater costs compared with those without SLE. Added costs were largely attributable to inpatient hospitalizations. The Medicare population is an important target for efforts to improve SLE disease management and reduce costs.

ABSTRACT

OBJECTIVE: To derive and validate a brief patient-completed instrument, the Lupus Impact Tracker (LIT), to assess and monitor the impact of systemic lupus erythematosus (SLE). METHODS: Items for the LIT were selected from the LupusPRO, a validated patient-reported outcomes measure, using 3 approaches: confirmatory factor analysis (CFA), stepwise regression, and patient focus groups. CFA was conducted to find items from the LupusPRO that fit a unidimensional structure to allow scoring as a single index. Stepwise regression methods identified items with the strongest relationship (convergent validity) with disease activity measures and patient health rating. Focus groups (n = 26 patients) identified the most important items describing SLE impact. Selected items were evaluated for reliability and validity. RESULTS: CFA found 21 items that fit a unidimensional structure. Stepwise regressions identified 15 of 21 items having good convergent validity with clinical measures. Patient focus groups identified 9 of 15 items as best capturing the impact of SLE. Overall, 7 items were selected across all 3 approaches (CFA, stepwise regression, and focus groups). Another 15 items were selected across 2 approaches. Through consensus with rheumatology clinician experts, a final set of 10 items was selected for the LIT. The LIT items showed good internal consistency (0.89) and test-retest reliabilities (0.87). Mean LIT scores differed significantly (P < 0.05) across criterion groups in the hypothesized direction, providing evidence of discriminant validity and responsiveness. CONCLUSION: The LIT is reliable and valid in SLE patients and offers a practical way for physicians and patients to assess and monitor the impact of SLE.

ABSTRACT

OBJECTIVE: To assess healthcare resource utilization and costs in a cohort of US managed care patients with systemic lupus erythematosus (SLE). METHODS: Claims data from a large managed care plan were used to identify patients of 18-64 years old with SLE-related claims from 2004-2005. Algorithms were developed to retrospectively categorize patients by disease severity and identify flare episodes by flare severity. Descriptive and multivariate analyses were performed to estimate healthcare resource utilization and costs over a 2-year period for the cohort overall and by disease and flare severity. RESULTS: Among the 2990 patients in the study cohort, disease severity was mild in 789 (26.4%), moderate in 1558 (52.1%), and severe in 643 (21.5%). During the 2-year follow-up period, SLE patients utilized the following categories of care: office visit (99.7%), laboratory service (99.5%), outpatient hospital visit (76.0%), emergency room visit (45.6%), and inpatient hospital stay (26.4%). Mean total unadjusted healthcare cost per patient was $30,010 over the 2-year follow-up period, with medical and pharmacy costs comprising 76.5% and 23.5% of total expenditures, respectively. Additionally, 95.7% of patients had one or more flares, with a mean (SD) of 6.7 (3.6) flares during the 2-year follow-up period. The average unadjusted cost per mild, moderate, and severe flare, respectively, was $909, $1539, and $17,059, most of which was for medical cost rather than pharmacy cost. The frequency and cost of flares increased with disease severity. LIMITATIONS: The disease severity and flare severity algorithms were based upon managed care claims data; the algorithm was not verified clinically and may not be generalizable to other health plans. CONCLUSIONS: SLE is associated with high levels of healthcare utilization and costs in a managed care health plan. Inpatient hospital stays were the primary medical cost drivers, followed by physician office visits and outpatient hospital visits.

ABSTRACT

BACKGROUND: The Rhinitis Control Assessment Test (RCAT) is a brief, patient-completed tool to evaluate rhinitis symptom control. OBJECTIVE: We sought to test the reliability, validity, and responsiveness of RCAT and to estimate a cut-point score and minimal important difference (MID). METHODS: A total of 402 patients 12 years of age and older with allergic or nonallergic rhinitis were enrolled in a noninterventional study. Patients completed the RCAT (6 items; score range, 6-30) and had Total Nasal Symptom Scores (TNSSs) measured at baseline and 2 weeks later. Physicians completed a global assessment of rhinitis symptom control (Physician's Global Assessment) and disease severity. Internal consistency, test-retest reliability, convergent validity, known-groups validity, and responsiveness were evaluated. The MID was determined by using distribution- and anchor-based methods. Content validity of the RCAT was assessed in individual interviews with a separate group of 58 adult patients. RESULTS: Internal consistency and test-retest reliability of RCAT scores were 0.77 and 0.78, respectively. Convergent validity correlation between RCAT and TNSS scores was 0.57, and that between RCAT and Physician's Global Assessment scores was 0.34. Mean RCAT scores differed significantly (P < .001) across patient groups, differing in TNSS (F = 72.7), Physician's Global Assessment score (F = 28.6), and disease severity (F = 34.1) in the hypothesized direction. Results suggested a cut-point score of 21 or less can be used to identify patients who are experiencing rhinitis symptom control problems. The preliminary estimate of the MID was 3 points. Patients found RCAT items comprehensive, easy to understand, and relevant. CONCLUSION: The RCAT demonstrated adequate reliability, validity, and responsiveness and was deemed acceptable and appropriate by patients. This tool can facilitate the detection of rhinitis symptom control problems, and its brevity supports its usefulness in clinical care.

ABSTRACT

BACKGROUND: Uncomplicated acute rhinosinusitis (ARS) is usually a self-limiting inflammatory condition often treated with antibiotics. AIMS: To assess the safety and efficacy of fluticasone furoate nasal spray (FFNS) compared with placebo for symptomatic relief of uncomplicated ARS. METHODS: A randomised, double-blind, placebo-controlled, parallel-group, multicentre, 2-week treatment study of FFNS 110 µg once and twice daily was undertaken in adults/adolescents. RESULTS: A statistically significant reduction was seen in the daily major symptoms score, a composite score of three individual symptoms (nasal congestion/stuffiness, sinus headache/pressure or facial pain/pressure, and postnasal drip on a 0-3 scale) by both FFNS doses compared with placebo (least square mean differences vs. placebo of -0.386 (p=0.008) and -0.357 (p=0.014) for once daily and twice daily FFNS, respectively). The differences in median times to symptom improvement were not statistically significant between each dose of FFNS (7 days) and placebo (8 days). There were no treatment differences in antibiotic use for possible fulminant bacterial rhinosinusitis (3% in each group). The safety profile of FFNS was similar to placebo. CONCLUSIONS: FFNS reduces symptoms of uncomplicated ARS compared with placebo and is well tolerated, providing support for withholding antibiotics in selected patients.

ABSTRACT

BACKGROUND: The relationships between validated quality of life tools and control tools have not been explored for rhinitis. This study was designed to determine relationships of the Mini-Rhinitis Quality of Life Questionnaire (MiniRQLQ) and the Rhinitis Control Assessment Test (RCAT) to each other regarding content and predictive abilities. METHODS: Participants were adult members of a large integrated care organization with an encounter diagnosis of rhinitis in the prior 2 years. Patients completed mailed questionnaires at baseline that contained the MiniRQLQ and the RCAT and three follow-up questionnaires that contained those tools as well as questions regarding missed work or school because of rhinitis and frequency and effectiveness of medications used for rhinitis. Medications dispensed during the follow-up year were obtained from computerized pharmacy records. Results of allergy tests were retrieved for patients seen in the Allergy Department. RESULTS: The final cohort included 1051 patients. Baseline RCAT scores were strongly correlated with baseline MiniRQLQ scores in both allergic (r = -0.80) and nonallergic (r = -0.84) patients. Baseline MiniRQLQ and RCAT scores were significantly related to patient reports of missed school/work, medication use, and effectiveness over the next 3 months and to dispensing during the following year of total and some individual rhinitis medications. Test-retest reliability, responsiveness, and a preliminary minimal important difference (>2.5) were shown for the RCAT, using the MiniRQLQ as an anchor. CONCLUSION: The MiniRQLQ and RCAT are strongly related to each other and both predict subsequent rhinitis outcomes. Determining the comparative usefulness of these tools will require further study.

ABSTRACT

BACKGROUND: Relationships of asthma control to other asthma outcomes have been incompletely documented. OBJECTIVE: This study examined the relationship between asthma control and health-related quality of life (HRQL) and subsequent healthcare resource utilization. METHODS: A 1-year online prospective longitudinal survey was conducted in 497 adults and 170 children with asthma treated in the past year. Control was measured by Asthma Control Test™ (ACT) and Childhood ACT™ (C-ACT)™ scores dichotomized into "well-controlled" (scores >19) or "not well-controlled" (scores ≤19), and HRQL was measured using the PedsQL™ 3.0 Asthma Module (children) and the SF-12 Health Survey (adults). Multivariate models were used for analysis. RESULTS: HRQL scores were significantly lower for adults (mean decrease 3.4) and children (mean decrease 12.8) whose asthma was not well-controlled compared to patients with well-controlled asthma. Adults with asthma that was not well-controlled at baseline had a threefold greater risk of an asthma-related doctor visit and a 10-fold greater risk of an emergency department (ED) visit for asthma in the subsequent 9 months (odds ratio (OR) = 3.3 and OR = 11.3, respectively). Children with asthma that was not well-controlled had a nearly fivefold increased risk for subsequent asthma-related doctors' and ED visits (OR = 4.8 and OR = 4.9, respectively). CONCLUSION: Both adults and children with not well-controlled asthma had significantly lower quality of life and were more likely to require an office or ED visit for asthma compared to patients with higher ACT scores. Therefore, it is important to continually assess asthma control and adjust controller therapy accordingly.

ABSTRACT

BACKGROUND: Intranasal corticosteroids are first-line treatment for moderate-to-severe seasonal allergic rhinitis (AR). OBJECTIVES: To compare preferences for fluticasone furoate and fluticasone propionate nasal sprays after 1 week of treatment in patients with symptomatic seasonal AR. METHODS: Patients with seasonal AR were enrolled (n = 360) and randomized 1:1 to active treatment (fluticasone furoate, 110 microg, or fluticasone propionate, 200 microg, followed by crossover treatment for 1 week each) or matched placebo sequence with a 1-week washout before crossover dosing. Fluticasone furoate and fluticasone propionate efficacy was measured by change from baseline during 1 week in daily reflective total nasal symptom score (rTNSS) that assessed severity of rhinorrhea, nasal congestion, nasal itching, and sneezing. Patient preference for fluticasone furoate or fluticasone propionate was assessed at the end of the study by questionnaire. RESULTS: Three hundred sixty patients from 29 clinical sites in the Unites States were randomized and treated between August 1, 2007 and November 30, 2007. Most patients were white (73%) and female (59%), with a mean age of 38.3 years, and had had seasonal AR for at least 10 years (74%). Fluticasone furoate and fluticasone propionate each reduced the daily rTNSS compared with their respective placebos (least squares mean [SD] difference, -0.8 [0.24], P < .001, and -0.6 [0.24], P = .01, respectively). More patients (P < .001) preferred fluticasone furoate to fluticasone propionate based on attributes of scent or odor (58% vs 27%), aftertaste (60% vs 18%), leaking out of the nose and down the throat (59% vs 21%), and mist gentleness (57% vs 26%). No statistically significant differences were seen in preferences regarding ease of use, delivery method, or device comfort. CONCLUSION: Both fluticasone furoate and fluticasone propionate significantly improved symptoms in adult patients with seasonal AR. Most patients preferred the sensory attributes of fluticasone furoate to those of fluticasone propionate after 1 week of treatment.
