Time to next treatment in patients with chronic lymphocytic leukemia initiating first-line ibrutinib or acalabrutinib.

Aim: To investigate real-world time to next treatment in patients with chronic lymphocytic leukemia initiating first-line (1L) ibrutinib or acalabrutinib. Materials & methods: US specialty pharmacy electronic medical records (21/11/2018-30/4/2022) were used; patients initiated 1L on/after 21/11/2019 (acalabrutinib approval). Results: Among 710 patients receiving ibrutinib, 5.9% initiated next treatment (mean time to initiation = 9.2 months); among 373 patients receiving acalabrutinib, 7.5% initiated next treatment (mean time to initiation = 5.9 months). Adjusting for baseline characteristics, acalabrutinib-treated patients were 89% more likely to initiate next treatment (hazard ratio = 1.89; p = 0.016). Conclusion: This study addresses a need for real-world comparative effectiveness between 1L ibrutinib and acalabrutinib and shows that next treatment (a clinically meaningful measure for real-world progression) occurred less frequently with 1L ibrutinib.

Ibrutinib and acalabrutinib are oral medications taken once-daily and twice-daily, respectively. They are recommended as initial treatment for chronic lymphocytic leukemia (CLL). The goal of this study was to compare the efficacy of these treatments as initial treatment for CLL. To meet this goal, real-world US specialty pharmacy electronic medical records between 11/21/2018­4/30/2022 were used. Patients treated with ibrutinib or acalabrutinib as initial treatment for CLL were studied. Treatment had to be started on or after the date of acalabrutinib approval for CLL (11/21/2019). Time to next treatment was used to estimate real-world disease progression. It was defined as the time from the initiation of initial treatment with ibrutinib or acalabrutinib to the initiation of a next treatment. Study results showed that patients were observed for a median of up to 1.5 years. Over this period, next treatment was more likely for acalabrutinib (7.5%) compared with ibrutinib (5.9%). After adjusting for differences in patient characteristics, next treatment was 89% more likely with acalabrutinib than ibrutinib. This study addresses a need to compare the effectiveness of initial treatment with ibrutinib and acalabrutinib in the real-world. It helps better contextualize results from clinical trial data and shows that next treatment occurred less frequently with ibrutinib.

Real-world time to discontinuation of first-line venetoclax + obinutuzumab in chronic lymphocytic leukemia/small lymphocytic lymphoma.

OBJECTIVE: To evaluate the time to discontinuation (TTD) and baseline characteristics among patients with chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL) treated with first-line (1L) venetoclax + obinutuzumab (VO) in the United States. METHODS: A nationwide electronic health record-derived database was used to select adults with CLL/SLL initiating a 1L venetoclax-based regimen between April 11, 2016-July 31, 2020. Study measures included TTD (defined as >120-day treatment gap or switching therapy) and baseline characteristics by discontinuation status. RESULTS: A total of 113 patients receiving 1L VO on/before July 31, 2020 were eligible for analysis (mean age: 65.9 years; 31.9% women). During the first 60 days post-treatment initiation, 3.5% had tumor lysis syndrome (TLS). The proportion of patients using corticosteroids, anti-hyperuricemics, and anti-emetics was higher during the first 60 days post-treatment initiation (100.0%, 78.8%, and 52.2%, respectively) than the period from day 61 onward (67.0%, 45.5%, and 33.9%, respectively). Mean (median) duration of active treatment was 11.6 (12.1) months; 16.8% discontinued treatment before completing 12 cycles, 68.1% completed ≥12 cycles (among which 29.9% completed ≥15 cycles), and 15.0% who did not discontinue treatment were censored before completing 12 cycles. Kaplan-Meier analysis showed that median TTD was 13.8 months. Relative to those completing ≥12 cycles, patients discontinuing treatment before completing the prescribed 12 cycles were older (70.4 vs. 65.1 years) and had poorer renal function (36.8% vs. 13.0% with creatinine clearance <60 mL/min). CONCLUSION: A small proportion of CLL/SLL patients who were older and had poorer baseline renal function discontinued 1L VO prior to completing 12 treatment cycles. Additionally, treatment utilization, including medications related to TLS mitigation and management, was more intense during the initiation phase of VO. Further research with longer follow-up to assess long-term outcomes of VO treatment after early discontinuation is warranted.

Real-World Comparison of First-Line Treatment Adherence Between Single-Agent Ibrutinib and Acalabrutinib in Patients with Chronic Lymphocytic Leukemia.

Purpose: Increased dosing frequency adversely affects treatment adherence and outcomes in chronic diseases; however, such data related to treatment adherence is lacking in chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL). This study compared adherence between patients treated with ibrutinib (once-daily) versus acalabrutinib (twice-daily) as first-line (1L) therapy for CLL/SLL. Patients and Methods: Specialty pharmacy electronic medical records were used to identify adults with CLL/SLL initiating 1L ibrutinib or acalabrutinib between 01/01/2018 and 11/30/2020. Adherence was measured by the proportion of days covered (PDC) and medication possession ratio (MPR) and was compared between cohorts using odds ratios (ORs) obtained from logistic regression models adjusted for baseline characteristics. Results: Between 01/01/2018 and 11/30/2020, 1374 and 140 patients initiated ibrutinib and acalabrutinib, respectively. Based on PDC/MPR ≥80%, patients treated with once-daily ibrutinib were more likely to be adherent than those treated with twice-daily acalabrutinib (OR ranges: PDC: 1.04-1.76; MPR: 1.03-1.58). At 6 months, patients on ibrutinib had a 58-76% higher likelihood of staying adherent compared to patients on acalabrutinib (PDC: 75.9% for ibrutinib vs 63.6% for acalabrutinib, OR: 1.76, P=0.008; MPR: 76.8% vs 66.9%, OR: 1.58, P=0.036) with a similar trend noted for the entire line of treatment (LOT) (PDC: 53.0% vs 41.4%, OR: 1.53, P=0.021; MPR: 58.7% vs 47.1%, OR: 1.50, P=0.027). Conclusion: In this real-world analysis, CLL/SLL patients initiating 1L once-daily ibrutinib had >50% higher treatment adherence than those initiating twice-daily acalabrutinib during their LOT. Given the importance of sustained adherence for disease control in CLL/SLL, dosing frequency may be an important consideration for patients and physicians.

Hypnotic prescription trends and patterns for the treatment of insomnia in Japan: analysis of a nationwide Japanese claims database.

BACKGROUND: There is limited consensus regarding the optimal treatment of insomnia. The recent introduction of orexin receptor antagonists (ORA) has increased the available treatment options. However, the prescribing patterns of hypnotics in Japan have not been comprehensively assessed. We performed analyses of a claims database to investigate the real-world use of hypnotics for treating insomnia in Japan. METHODS: Data were retrieved for outpatients (aged ≥ 20 to < 75 years old) prescribed ≥ 1 hypnotic for a diagnosis of insomnia between April 1st, 2009 and March 31st, 2020, with ≥ 12 months of continuous enrolment in the JMDC Claims Database. Patients were classified as new or long-term users of hypnotics. Long-term use was defined as prescription of the same mechanism of action (MOA) for ≥ 180 days. We analyzed the trends (2010-2019) and patterns (2018-2019) in hypnotics prescriptions. RESULTS: We analyzed data for 130,177 new and 91,215 long-term users (2010-2019). Most new users were prescribed one MOA per year (97.1%-97.9%). In 2010, GABAA-receptor agonists (benzodiazepines [BZD] or z-drugs) were prescribed to 94.0% of new users. Prescriptions for BZD declined from 54.8% of patients in 2010 to 30.5% in 2019, whereas z-drug prescriptions remained stable (~ 40%). Prescriptions for melatonin receptor agonist increased slightly (3.2% to 6.3%). Prescriptions for ORA increased over this time from 0% to 20.2%. Prescriptions for BZD alone among long-term users decreased steadily from 68.3% in 2010 to 49.7% in 2019. Prescriptions for ORA were lower among long-term users (0% in 2010, 4.3% in 2019) relative to new users. Using data from 2018-2019, multiple (≥ 2) MOAs were prescribed to a higher proportion of long-term (18.2%) than new (2.8%) users. The distribution of MOAs according to psychiatric comorbidities, segmented by age or sex, revealed higher proportions of BZD prescriptions in elderly (new and long-term users) and male (new users) patients in all comorbidity segments. CONCLUSION: Prescriptions for hypnotics among new and long-term users in Japan showed distinct patterns and trends. Further understanding of the treatment options for insomnia with accumulating evidence for the risk-benefit balance might be beneficial for physicians prescribing hypnotics in real-world settings.

Factors Associated with Prescriptions for an Orexin Receptor Antagonist Among Japanese Patients with Insomnia: Analysis of a Nationwide Japanese Claims Database.

BACKGROUND: Few studies have examined the prescribing patterns of orexin receptor antagonists (ORAs) in the real-world clinical setting in Japan. OBJECTIVE: We sought to analyze the factors associated with ORA prescriptions for patients with insomnia in Japan. METHODS: Outpatients (aged ≥ 20 to < 75 years old) prescribed one or more hypnotic for insomnia between April 1, 2018 and March 31, 2020 with continuous enrollment for ≥ 12 months were extracted from the JMDC Claims Database. We performed multivariable logistic regression to identify factors (patient demographics and psychiatric comorbidities) associated with ORA prescription in new or non-new users of hypnotics (patients without or with hypnotics prescription history, respectively). RESULTS: Of 58,907 new users, 11,589 (19.7%) were prescribed ORA at the index date. Male sex (odds ratio [OR] 1.17, 95% confidence interval [CI] 1.12-1.22) and presence of bipolar disorders (OR 1.36, 95% CI 1.20-1.55) were associated with greater odds of ORA prescription. Among 88,611 non-new users, 15,504 (17.5%) were prescribed ORA at the index date. Younger age and several psychiatric comorbidities, such as neurocognitive disorders (OR 1.64, 95% CI 1.15-2.35), substance use disorders (OR 1.19, 95% CI 1.05-1.35), bipolar disorders (OR 1.14, 95% CI 1.07-1.22), schizophrenia spectrum disorders (OR 1.07, 95% CI 1.01-1.14), and anxiety disorders (OR 1.05, 95% CI 1.00-1.10), were associated with greater odds of ORA prescription. CONCLUSION: This is the first study to determine the factors associated with ORA prescriptions in Japan. Our findings could help guide appropriate insomnia treatment using ORAs.

A Feasibility Study: Testing Whether a Sleep Application Providing Objective Sleep Data to Physicians Improves Patient-Physician Communication Regarding Sleep Experiences, Habits, and Behaviors.

INTRODUCTION: Sleep tracker data have not been utilized routinely in sleep-related disorders and their management. Sleep-related disorders are common in primary care practice and incorporating sleep tracker data may help in improving patient care. We conducted a pilot study to assess the feasibility of a sleep program using the Fitbit Charge 2™ device and SleepLife® application. The main aim of the study was to examine whether a program using a commercially available wearable sleep tracker device providing objective sleep data would improve communication in primary care settings between patients and their providers. Secondary aims included whether patient satisfaction with care would improve as result of the program. METHODS: A prospective, randomized, parallel group, observational pilot study was conducted in 20 primary care clinics in Indianapolis, IN from June 2018 to February 2019. Inclusion criteria included patients over the age of 18, have a diagnosis of insomnia identified by electronic medical record and/or a validated questionnaire, and were on a prescription sleep aid. The study was not specific to any sleep aid prescription, branded or generic, and was not designed to evaluate a drug or drug class. Each primary care clinic was randomized to either the SleepLife® intervention or the control arm. All patients were provided with a Fitbit Charge 2™ device. Only patients in the intervention arm were educated on how to use the SleepLife® application. Physicians in the intervention arm were set up with the SleepLife® portal on their computers. RESULTS: Forty-nine physicians and 75 patients were enrolled in the study. Patients had a mean age of 57 (SD 12.8) years and 61% were female. Mean age of physicians was 47 (SD 10.6) years. Patients showed high rates of involvement in the program with 83% completing all survey questions. Physician survey completion rate was 55%. Only one physician logged into the SleepLife portal to check their patients' sleep status. At the end of the 6-week intervention, patients' composite general satisfaction scores with sleep health management decreased significantly in the intervention arm when compared to controls (p = 0.03). Patients' satisfaction with communication also decreased significantly in the intervention group (p = 0.01). The sleep outcomes, which were calculated on the basis of study questionnaire answers, improved significantly in the intervention group as compared to the control group (p = 0.04). Physician communication satisfaction scores remained unchanged (p = 0.12). CONCLUSIONS: SleepLife® and its related physician portal can facilitate physician-patient communication, and it captures patient sleep outcomes including behaviors and habits. Patients were highly engaged with the program, while physicians did not demonstrate engagement. The study design and questionnaires do not specifically address the reasons behind the decreased patient satisfaction with care and communication, but it was perceived to be a result of physician non-responsiveness. Sleep quality scores on the other hand showed an improvement among SleepLife® users, suggesting that patients may have implemented good sleep practices on their own. Given that it was a feasibility study, and the sample size was small, we were not able to make major inferences regarding the difference between sleep disorder types. Additionally, we excluded patients with a history of alcohol use, substance abuse, or depression because of concerns that they may affect sleep independently. To promote the growth of technology in primary care, further research incorporating results from this study and physician engagement techniques should be included.

Burden of Insomnia and Sleep Disturbances and the Impact of Sleep Treatments in Patients with Probable or Possible Alzheimer's Disease: A Structured Literature Review.

BACKGROUND: Sleep disturbances are frequent in Alzheimer's disease (AD). OBJECTIVE: To summarize the impact of sleep disturbances on AD patients and their caregivers and the effects of currently available sleep therapies. METHODS: Published studies (January 1985-March 2020) assessing the burden associated with insomnia/sleep disturbances in the AD population and insomnia treatment effects were identified by searching PubMed, Embase, and Cochrane Library and screened against inclusion criteria. RESULTS: 58 studies assessing patient and caregiver burden, institutionalization, and insomnia treatments in AD patients with sleep disturbances were identified. Sleep disturbances were associated with worse cognition, functional ability, and behavioral and neuropsychological functioning. Health status and quality of life of both patients and caregivers were reduced in the presence of sleep disturbances. Sleep disturbances were also associated with institutionalization. Although significant associations between sleep problems and clinical outcomes were apparent, there was generally no control for other influencing factors (e.g., cognitive status). Bright light and behavioral therapies as well as drugs showed some promise in AD patients, but studies were primarily small and limited data were available, particularly in regard to the effect on associated clinical burden. CONCLUSION: Sleep disturbances are a significant problem for AD patients and caregivers, associated with behavioral and psychological problems and cognitive decline. However, they remain poorly characterized and under-researched. As the global population is aging and AD is on thes rise, data from larger, prospective trials are required to fully understand the clinical correlates of sleep disturbances and the impact insomnia treatments can have.

Health-Care and Societal Costs Associated with Non-Persistence with Subcutaneous TNF-α Inhibitors in the Treatment of Inflammatory Arthritis (IA): A Retrospective Observational Study.

OBJECTIVE: A few studies have suggested that patients with inflammatory arthritis (IA) who remain persistent with subcutaneous TNF-α inhibitors (SC-TNFi) incur lower health care costs than patients who discontinue treatment, whereas data on the impact of non-persistence on indirect costs are largely lacking. Furthermore, existing estimates are based on fixed follow-ups, in relation to treatment initiation, and therefore do not measure costs in direct relation to treatment discontinuation. Therefore, by capturing costs in direct relation to treatment discontinuation, this study aimed to estimate direct and indirect costs associated with non-persistence with SC-TNFis in IA. METHODS: Adult Swedish biologic-naïve IA patients initiating biologic treatment with a SC-TNFi (adalimumab, etanercept, certolizumab or golimumab) between May 6, 2010, and December 31, 2017, were identified in population-based registers with almost complete coverage. IA was defined as a diagnosis of rheumatic arthritis, ankylosing spondylitis/unspecified spondyloarthritis or psoriatic arthritis. Non-persistent patients were matched on propensity score to patients persistent with treatment by at least an additional 12 months. This enabled comparisons of direct healthcare costs and indirect costs for sick leave and disability pension, respectively, 12 months before and 12 months after treatment discontinuation. RESULTS: A balanced cohort of 486 matched pairs was generated. The total direct and indirect costs were significantly higher among non-persistent patients already during the 12 months before index ($20,802 [18,335-23,429] vs. $16,600 [14,331-18,696]). However, while non-persistent patients increased their total direct and indirect costs, persistent patients significantly decreased the same, further widening the difference in costs during the 12-month period after index date ($22,161 [19,754-24,556] vs. $13,465 [11,415-15,729]). CONCLUSIONS: Among biologic-naïve Swedish IA patients treated with SC-TNFis, persistent patients incurred about 40% lower aggregated direct and indirect costs compared to non-persistent patients the year following SC-TNFi discontinuation. This highlights the impact of treatment persistence from an economic viewpoint, adding further aspects to the clinical perspective.

Incremental Healthcare Utilization and Cost Burden of Comorbid Insomnia in Alzheimer's Disease Patients.

BACKGROUND: Insomnia is associated with worsened clinical outcomes among Alzheimer's disease dementia (AD) patients, increased caregiver burden, and healthcare utilization. OBJECTIVE: This study aimed to characterize the incremental healthcare burden of insomnia in AD using real-world data. METHODS: A retrospective observational study was conducted on AD patients selected from the IBM® MarketScan Commercial and Medicare Supplemental Databases. AD patients with claims-based evidence of insomnia were direct matched to a non-insomnia cohort based on demographic factors. Healthcare utilization and associated costs were assessed for a 12-month follow-up period. RESULTS: A total of 3,500 insomnia AD patients and 9,884 non-insomnia AD patients were analyzed. The insomnia cohort had a higher comorbidity burden at baseline (mean score on Charlson Comorbidity Index 2.5 versus 2.2, p < 0.001) and higher proportions of patients with baseline diagnoses for other conditions including depression: 40%, insomnia cohort versus 25%, non-insomnia (p < 0.001). AD patients with insomnia were more likely to have a claim for inpatient hospitalizations (39.8%versus 32.3%), emergency room services (56.4%versus 48.0%), and skilled-nursing services (42.6%versus 31.9%) (all p < 0.05). Mean total annual healthcare costs during the 12-month follow-up period were significantly higher among AD patients with insomnia as compared to those without. (Mean costs: $37,356 versus $27,990, p < 0.001). CONCLUSION: AD patients with comorbid insomnia are more likely to use higher-cost healthcare services such as inpatient hospitalization, and skilled nursing, and have higher total healthcare costs. This real-world analysis provides evidence that AD disease management should consider proper treatment of comorbid insomnia due to the incremental burden and cost implications.

Changes in Healthcare Resource Use and Costs in Commercially Insured Insomnia Patients Initiating Suvorexant.

INTRODUCTION: Insomnia diagnosis has been associated with a significant clinical and economic burden on patients and healthcare systems. This study examined changes in healthcare resource use (HCRU) and costs in insomnia patients before and after initiation of suvorexant treatment. METHODS: This retrospective cohort study analyzed Optum Clinformatics Data Mart claims data (Jan 2010-Dec 2018). Patients with ≥ 2 insomnia diagnosis claims and ≥ 1 prescription for suvorexant were included. Prevalent and incident insomnia patients were analyzed separately. The change in the trends of HCRU and costs were examined for 12 months before and 12 months after suvorexant initiation. An interrupted time series (ITS) analysis was conducted to assess the level and slope changes. Subgroups of patients with mental health comorbidities were examined. RESULTS: The study included 18,919 and 5939 patients in the prevalent and incident insomnia cohorts, respectively. For the prevalent cohort, mean (SD) age was 64.5 (14.1) years, 65% were female, 74% had Medicare Advantage coverage, and 61% had a Charlson comorbidity index score ≥ 1. Characteristics for the incident cohort were similar. The ITS results suggested that the trend for monthly total healthcare cost (THC) was increasing before suvorexant initiation (US$52.51 in the prevalent cohort, $74.93 in incident insomnia cohort), but, after suvorexant initiation, the monthly total cost showed a decreasing trend in both cohorts. The decrease in slope for THC after suvorexant initiation were $72.66 and $112.07 per month in the prevalent and incident cohorts, respectively. The monthly trends in HCRU rates also decreased. The subgroup analysis showed that decreases were 1.5-3 times greater for patients with mental health comorbidities. CONCLUSIONS: In this real-world study, suvorexant initiation was associated with immediate and continued decreases in HCRU and costs in insomnia patients. Further research is needed to understand the effect of suvorexant initiation on direct medical costs as well as costs associated with lost productivity in other real-world settings.

A Real-World Assessment of Outcomes in Schizophrenia Patients According to Treatment Response.

OBJECTIVE: To describe and compare demographics, outcomes, and comorbidities among schizophrenia patients according to treatment response. METHODS: A cross-sectional survey was conducted in the United States through the Adelphi Schizophrenia Disease Specific Program from January to May 2014. Participating physicians provided information on the first 10 schizophrenia patients aged ≥ 18 years they saw in daily clinical practice; these patients were invited to voluntarily complete a patient self-completion form. Patients were considered partial responders or responders based on the physician-reported Clinical Global Impressions improvement scale. Regression analyses were performed to identify potential drivers of response and the clinical and humanistic outcomes associated with response. RESULTS: 150 physicians provided data on 433 partial responders and 872 responders; 185 partial responders and 415 responders completed a patient self-completion form. A significant predictor of response was always being adherent with the medication regimen (P < .001). Positive symptoms (P = .006) and moderate (P = .004) or severe (P = .002) illness severity were significant predictors of inadequate response. Responders were more likely to have better EQ-5D (EuroQol 5 Dimensions) visual analog scale, Quality of Life Enjoyment and Satisfaction Questionnaire, and work productivity and impairment scores (all P < .05). CONCLUSIONS: Partial responders were more likely to have significantly poorer clinical and quality of life outcomes compared with responders. Improved therapeutic approaches, either new therapies or optimized treatments, could lead to both better outcomes and improved adherence in this population.

Assessment of Real-Life Outcomes in Schizophrenia Patients according to Compliance.

OBJECTIVE: To describe and compare demographics, outcomes and comorbidities in schizophrenia patients by treatment compliance. METHODS: This was a cross-sectional survey of hospital- or office-based psychiatrists who saw ≥6 schizophrenia patients per week and were responsible for treatment decisions. Recruited physicians completed a patient record form (PRF) for their first 10 consulted schizophrenia patients aged ≥18. These patients voluntarily completed a patient self-completion form (PSC). Compliance was measured by subjective physician assessment. Drivers of and outcomes associated with compliance were identified by regression analyses. RESULTS: A total of 150 physicians completed PRFs for 1489 patients (706 sometimes compliant (SC), 636 always compliant (AC)). A total of 680 patients completed a PSC (327 SC, 295 AC). AC patients were less likely to be male (52.2% vs. 58.6%; P = 0.021) and unemployed (odds ratio (OR) 0.91, 95% confidence interval (CI) 0.82-1.00; P < 0.001) or to have had a treatment regimen change (OR 0.56, 95% CI 0.40-0.80; P = 0.001) than SC patients. AC patients were less likely to have had more comorbidities (OR 0.91, 95% CI 0.82-1.00; P = 0.045) and hospitalizations in the past 12 months (OR 0.59, 95% CI 0.43-0.80; P = 0.001) than SC patients. Overall, AC patients had better clinical and humanistic outcomes. Weight gain was a common side effect for all patients; SC patients with weight gain had poorer outcomes than those without weight gain. CONCLUSION: Schizophrenia patients that were SC experienced poorer clinical outcomes and quality of life. Weight gain may exacerbate these poorer outcomes.

Dose-Dependent Hyperkalemia Among Hospitalized, HIV-Infected Patients Receiving Sulfamethoxazole/Trimethoprim.

Background: Sulfamethoxazole-trimethoprim (SXT) therapy is commonly used in HIV-infected patients and is associated with hyperkalemia and elevated serum creatinine (SCr). Objective: The purpose of this study was to examine the frequency of hyperkalemia and elevated SCr in hospitalized, HIV-infected patients receiving SXT. Methods: This was a retrospective, single-center cohort study. HIV-infected hospitalized patients receiving a minimum of 3 consecutive days of SXT were included. Patients were grouped according to high dose (≥10 mg/kg/d) and low dose (<10 mg/kg/d) trimethoprim. The primary end point was the frequency of hyperkalemia, severe hyperkalemia, and elevated SCr. Secondary end points included an evaluation of concomitant potassium-altering medications and concomitant nephrotoxic drugs. Results: A total of 100 consecutive patients were selected from all possible patients who met inclusion criteria. Overall, 47 patients experienced at least 1 adverse drug event (ADE) of either hyperkalemia or increased SCr, with 20 patients experiencing these ADEs in the low-dose group and 27 patients experiencing these ADEs in the high-dose group (P = 0.229). The ADEs of hyperkalemia or increased SCr occurred after a shorter period (5.5 vs 8.7 days) in the high-dose group (P = 0.049). Overall frequency of elevated SCr was 24% and of elevated serum K was 36%. Hyperkalemia requiring a therapeutic intervention occurred in 12 patients in the high-dose group compared with 2 in the low-dose group (P = 0.009). Conclusion and Relevance: Rates of elevated SCr and hyperkalemia in hospitalized HIV-infected patients receiving SXT are significant. Hyperkalemia requiring intervention is more common in patients receiving high-dose SXT.

Effects of women's autonomy on maternal healthcare utilization in Bangladesh: Evidence from a national survey.

OBJECTIVES: This study aims to construct an index of women's autonomy to analyze its effect on maternal healthcare utilization in Bangladesh. Empirical modeling of the study used instrumental variable (IV) approach to correct for possible endogeneity of women's autonomy variable. METHODS: Data from the Bangladesh Demographic and Health Survey (BDHS) 2011 was used for the study. Women's autonomy variable was obtained through factor analysis of variables related to autonomy in decision making regarding healthcare, financial autonomy and freedom of movement. Conditional mixed process (CMP) models were fitted for three maternal healthcare indicators: at least four antenatal care (ANC) by trained personnel, institutional delivery and postnatal care (PNC) by trained personnel. RESULTS: Study sample consisted of 8753 women with 5.5 mean years of schooling. Women with no formal education, of Islamic faith, from poorest wealth quintile, residing in rural areas and with low autonomy used the maternal healthcare least. Marginal effect shows that if women's autonomy score is increased by one unit, probability of maternal healthcare utilization will increase by 0.14 for ANC, 0.14 for institutional delivery, and 0.13 for PNC. CONCLUSIONS: Women's autonomy is an important driver of maternal healthcare utilization in Bangladesh. Results suggest that women participating in social and economic activities enhances their autonomy. Other factors affecting women's autonomy are female literacy, educational attainment and households' economic status.
