Finding significant indicators of PharmD academic performance to impact future students.

OBJECTIVE: The purpose of this study is to identify which factors, both objective and subjective, from a student pharmacist's background are significantly related to academic performance in the professional PharmD program. METHODS: Texas student pharmacists in their first three professional years during the 2022-2023 academic year were invited to participate in a 41-item survey to gather data on their undergraduate background, work experience, grit, and academic resilience. The survey responses were paired with the student pharmacist's cumulative grade point average (GPA) to assess the relationships between the variables and academic performance using Mann-Whitney U tests, Kruskal-Wallis tests, and Spearman's correlations. RESULTS: Two hundred and fifty-one student pharmacists currently enrolled in a PharmD program in Texas responded to the survey invitation. Spearman's rho correlations showed weak positive and significant relationships between GPA and Grit scores as well as GPA and Resilience scores. Additionally, there is a moderate positive and significant relationship between student pharmacists' Grit and Resilience scores. CONCLUSION: The results suggest that assessing for Grit or Resilience as part of the admission process could aid in identifying future student pharmacists who would experience pharmacy school academic success. Integrating tools that develop Grit and Resilience in the PharmD curriculum could improve student pharmacists' academic performance.

Treatment patterns and outcomes among adults with immune thrombocytopenia receiving pharmaceutical second-line therapies: a retrospective cohort study using administrative claims data.

OBJECTIVES: To describe and compare real-world treatment patterns and clinical outcomes among individuals with immune thrombocytopenia (ITP) receiving second-line therapies (rituximab, romiplostim, or eltrombopag). METHODS: A retrospective cohort study was conducted using a large administrative claims database (January 2013-May 2020) among continuously enrolled patients ≥18 years prescribed second-line ITP therapies. The index date was the date of the first claim of the study medications. Treatment patterns and outcomes were measured during the 12-month follow-up period. Inverse probability of treatment weighting (IPTW) was used to balance covariates across treatment groups. Multivariable logistic regression was used to compare treatment patterns and bleeding risk outcomes. RESULTS: A total of 695 patients were included (rituximab, N = 285; romiplostim, N = 212; eltrombopag, N = 198). After IPTW, all baseline covariates were balanced. Compared to eltrombopag, patients in the rituximab cohort were 57% more likely to receive other ITP therapies (systematic corticosteroids or third-line therapies) during the follow-up period (odds ratio [OR] = 1.571, p = .030). There was no significant difference in the odds of receiving a different second-line therapy or experiencing a bleeding-related episode among three groups (p > .050). Patients in the romiplostim cohort were 69% more likely to receive rescue therapy compared to those in the rituximab cohort (OR = 1.688, p = .025). CONCLUSION: Patients with ITP receiving rituximab were more likely to need other ITP therapies but did not experience higher risk of bleeding compared to those receiving eltrombopag or romiplostim. Benefits, risks, cost-effectiveness, and patient preference should all be considered in optimizing second-line therapy for ITP.

Pregnancy-related risk factors and receipt of postpartum care among Texas Medicaid pregnant enrollees: Opportunities for pharmacist services.

BACKGROUND: The United States (US) experiences the highest rate of maternal mortality of similar countries. Postpartum care (PPC) focused on chronic disease management is potentially lifesaving, especially among pregnancies complicated by risk factors such as diabetes, hypertension, and mental health conditions (MHCs), which are conditions in which pharmacists can have an impact. OBJECTIVE: To evaluate the prevalence of maternal mortality risk factors and their relationships with receipt of PPC among Texas Medicaid enrollees. METHODS: A retrospective study included women with a delivery between 3/25/2014-11/1/2019 who were continuously enrolled in Texas Medicaid during the study period from 84 days pre-delivery to 60 days post-delivery. PPC was defined as ≥1 visit associated with postpartum follow-up services. Maternal mortality risk factors (diabetes, hypertension, and MHCs) during and after pregnancy were identified using diagnoses and medication utilization. Age, race/ethnicity, cesarean delivery, and preterm birth served as covariates. Multivariable logistic regression was used to address the study objective. RESULTS: The sample (N = 617,010) was 26.5±5.7 years, primarily (52.8%) Hispanic, and 33.0% had cesarean deliveries and 9.3% had preterm births. Risk factor prevalence included: diabetes (14.0%), hypertension (14.3%), and MHCs during (6.3%) and after (9.1%) pregnancy. A majority (77.9%) had a PPC visit within 60 days of delivery. The odds of receiving PPC were 1.2 times higher for patients with diabetes (OR = 1.183; 95% CI = 1.161-1.206; P < 0.0001), 1.1 times higher for patients with hypertension (OR = 1.109; 95% CI= 1.089-1.130; P < 0.0001), and 1.1 times higher for patients with MHCs (OR=1.138; 95% CI = 1.108-1.170; P < 0.0001) than patients without, respectively. CONCLUSION: Over three-quarters of Texas Medicaid pregnant enrollees received PPC within 60 days of delivery and risk factors were prevalent and predictive of receipt of PPC. Pharmacists can have a positive impact on maternal health by addressing hypertension, diabetes, and MHC risk factors.

Part 2: Assessment of a virtual vs. onsite interview experience from the interviewer perspective.

INTRODUCTION: The University of Texas at Austin College of Pharmacy transitioned from onsite interviews to virtual interviews in fall 2020. There is limited literature on whether the virtual format impacts an interviewer's assessment of a candidate. This study examined interviewer ability to assess candidates and barriers to participation. METHODS: During the virtual interview process, interviewers utilized a modified multiple mini interview (mMMI) format to evaluate prospective college of pharmacy students. An 18-item survey was emailed to 62 interviewers from the 2020-2021 cycle. Virtual mMMI scores were compared to the previous year's onsite MMI scores. Descriptive statistics and thematic analysis were used to assess the data. RESULTS: The response rate to the survey was 53% (33/62), and 59% of interviewers preferred virtual interviews to in-person. Interviewers stated that there were fewer barriers to participation, increased comfort, and more time with applicants during virtual interviews. For six of the nine attributes evaluated, ≥ 90% of interviewers reported that they were able to assess applicants as well as they did in person. When comparing virtual and onsite MMI scores, seven of nine attributes were statistically significantly higher in the virtual cohort than onsite. CONCLUSIONS: From the perspective of interviewers, the virtual interview decreased barriers to participation and still allowed the ability to assess the candidates. While offering a choice of interview setting to interviewers could increase accessibility, the statistically significant difference in MMI scores between virtual and onsite formats suggests that additional standardization is required to offer both formats simultaneously.

Part 1: Assessment of a virtual vs. onsite interview experience from the interviewee perspective.

INTRODUCTION: The University of Texas at Austin College of Pharmacy transitioned the prospective student interview process for the incoming Class of 2025 from an onsite to a virtual Zoom interview. Differences between the two processes were assessed to determine utility of virtual interviews in the future. The objective was to compare preference, impact, and barriers to onsite and virtual interview experiences for prospective students. METHODS: A survey to assess interviewees' opinions regarding the interview process, preference, and barriers to participation was emailed to candidates following the 2020-2021 interviews. Responses were evaluated using descriptive statistics, chi-square, Mann-Whitney U tests, and constant comparison thematic analysis. RESULTS: The survey response rate was 40%. Of these, 54% preferred virtual interviews. Travel, lodging, and time were identified as barriers, with 80.5% of interviewees reporting at least one of these barriers. Respondents who chose time or had more barriers were more likely to prefer virtual interviews. Hosting a pre-interview day helped candidates prepare. Having a pharmacy student in the breakout room helped reduce stress. Interviewees were able to engage, showcase their personality, and learn the culture of the college despite the virtual nature. CONCLUSIONS: From an interviewee perspective, the virtual interview process is a viable method to continue. Virtual interviews decrease barriers to access for candidates unable to attend onsite interviews while still allowing candidates to feel engaged, learn about the program, and have a positive experience. Pharmacy institutions may consider virtual interviews as an alternative or supplement to onsite interviews.

Impact of adherence to hydroxyurea on health outcomes among patients with sickle cell disease.

Although new pharmaceutical therapy options have recently become available, hydroxyurea is still the most commonly used and affordable treatment option for sickle cell disease (SCD). This study aimed to update the evidence on hydroxyurea adherence and its association with clinical and economic outcomes among individuals with SCD. This retrospective study used Texas Medicaid claims data from 09/2011-08/2016. Individuals were included if they had ≥1 inpatient or ≥2 outpatient SCD diagnoses, had ≥1 hydroxyurea prescription, were 2-63 years of age, and were continuously enrolled in Texas Medicaid between 6 months before and 1 year after the first hydroxyurea prescription fill date (index date). Hydroxyurea adherence (Medication Possession Ratio; MPR), vaso-occlusive crisis (VOC)-related outcomes, healthcare utilization and expenditures (SCD-related and all-cause) during the 1 year following the index date were measured. Bivariate and multivariable analyses were used to address the study objectives. Among 1035 included individuals (age: 18.8 ± 12.5 years, female: 52.1%), 20.9% were adherent to hydroxyurea (defined as MPR≥0.8). After adjustment for demographic and clinical characteristics, compared to being non-adherent, adhering to hydroxyurea was significantly associated with: a lower risk (Odds Ratio [OR] = 0.480, p = .0007) and hazard rate (Hazard Ratio [HR] = 0.748, p = .0005) of a VOC event, fewer VOC events (Incidence Rate Ratio [IRR] = 0.767, p = .0009), fewer VOC-related hospital days (IRR = 0.593, p = .0003), fewer all-cause and SCD-related hospitalizations (IRR = 0.712, p = .0008; IRR = 0.707, p = .0008, respectively) and emergency department visits (IRR = 0.768, p = .0037; IRR = 0.746, p = .0041, respectively), and lower SCD-related total healthcare expenditures (IRR = 0.796, p = .0266). Efforts to increase adherence to hydroxyurea could improve clinical and economic outcomes among individuals with SCD.

Real-world opioid use among patients with migraine enrolled in US commercial insurance and risk factors associated with migraine progression.

BACKGROUND: Migraineurs may be categorized as having episodic migraine (EM: < 15 headache days/month) or chronic migraine (CM: ≥ 15 days/month for > 3 months with ≥ 8 days/month having features of migraine). Opioid use has been linked to progression from EM to CM. OBJECTIVE: To describe the utilization of opioid prescriptions among patients with migraine, to determine the association between opioid use and migraine progression, and to explore demographic and clinical risk factors for migraine progression. METHODS: This retrospective cohort study used Optum's deidentified Clinformatics Data Mart Database from January 2015 to December 2018. Adult patients with a migraine diagnosis and continuous health plan enrollment were included. Opioid use was measured by average daily morphine equivalent dose, also known as morphine milligram equivalent (MME). Descriptive statistics were used to summarize the opioid use by patient demographic and clinical characteristics. A Cox proportional hazards model with stepwise selection was used to determine the risk factors of new-onset CM. RESULTS: Overall, 35% of patients with migraine (27,331 of 78,134) received prescription opioids (> 0 MME/day) during the 12-month follow-up period. Higher opioid dosage was found in patients who had CM and comorbidities of interest. Compared with patients with EM, patients with CM were twice as likely to receive at least 20 MME/day (CM 3.8% vs EM 1.9%) and had a higher median opioid day supply (CM 20 vs EM 10) during follow-up. About 7% of patients with CM with at least 1 opioid prescription had at least 50 MME/day in any 90-day period during follow-up. A significant association was found between MME level and the likelihood of new-onset CM. Additional significant risk factors of migraine progression included younger age, female sex, South and West regions, and having a diagnosis of medication overuse headache, depression, back pain, or fibromyalgia (all P < 0.05). CONCLUSIONS: Despite guidelines and the availability of more migraine-specific treatments, opioids are still commonly prescribed to patients with migraines in real-world practice, especially for those with CM. In this study population, a higher risk of new-onset CM was associated with receiving higher opioid doses.

Healthcare utilization and costs among patients with chronic migraine, episodic migraine, and tension-type headache enrolled in commercial insurance plans.

OBJECTIVE: To quantify and compare healthcare utilization and costs for patients with chronic migraine (CM), episodic migraine (EM), and tension-type headache (TTH) enrolled in US commercial health plans. METHODS: This retrospective cohort study used the Optum Clinformatics® Data Mart database from January 2015 to December 2018. Adult patients with a diagnosis of EM, CM or TTH and at least 12 months of continuous enrollment before and after diagnosis were included. Inverse probability of treatment weighting was used to adjust for baseline differences among the three groups. Patient demographic and clinical characteristics at baseline, and healthcare utilization and costs during follow-up, were described and compared between the three groups. RESULTS: A total of 45,849 patients were included: 8955 with CM, 31,961 with EM, and 4933 with TTH. The total all-cause annual direct medical costs of patients with CM ($17,878) were 1.38 times higher (95% CI: 1.31-1.44) than those with EM ($12,986), and 2.26 times higher (95% CI: 2.08-2.47) than those with TTH ($7902). The annual migraine/TTH-related costs of patients with CM ($1869) were 4.19 times higher (95% CI: 3.92-4.48) than those with EM ($446), and 11.90 times (95% CI: 10.59-13.52) higher than those with TTH ($157). In the adjusted analyses, for all service categories (emergency department, inpatient, outpatient, and prescriptions), the expected costs in the migraine groups were higher than in the TTH group (all p < 0.001), while controlling for covariates. Main findings were consistent in both weighted and unweighted samples, and with both unadjusted and adjusted analyses. CONCLUSION: This study provides an updated assessment of healthcare utilization and expenditures for adult patients with primary headache disorders. Compared to TTH, migraine is associated with higher resource use and direct medical costs, especially for those with a chronic condition. Future studies are needed to understand the indirect medical costs (productivity loss) and humanistic burden (quality of life) between migraine and TTH.

Age-related prescription medication utilization for the -management of sickle cell disease among Texas Medicaid patients.

INTRODUCTION: Sickle cell disease (SCD) is associated with recurrent complications and healthcare burden. Although SCD management guidelines differ based on age groups, little is known regarding actual utilization of preventative (hydroxyurea) and palliative therapies (opioid and nonopioid analgesics) to manage complications. This study assessed whether there were agerelated differences in SCD index therapy type and SCD-related medication utilization. DESIGN AND PATIENTS: Texas Medicaid prescription claims from September 1, 2011 to August 31, 2016 were retrospectively analyzed for SCD patients aged 2-63 years who received one or more SCD-related medications (hydroxyurea, opioid, or nonopioid analgesics). OUTCOME MEASURES: The primary outcomes were SCD index drug type and medication utilization: hydroxyurea adherence, and days' supply of opioid, and nonopioid analgesics. Chi-square, analysis of variance, and Kruskal-Wallis tests were used. RESULTS: Index therapy percentages for included patients (N = 2,339) were the following: opioids (45.7 percent), nonopioids (36.6 percent), dual therapy-opioids and nonopioids (11.2 percent), and hydroxyurea (6.5 percent), and they differed by age-groups (χ2 = 243.0, p < 0.0001). Hydroxyurea as index therapy was higher among children (2-12:9.1 percent) compared to adults (26-40:3.7 percent; 41-63:2.9 percent). Opioids as index therapy were higher among adults (18-25:48.0 percent; 26-40:54.9 percent; 41-63:65.2 percent) compared to children (2-12:36.6 percent). Mean hydroxyurea adherence was higher (p < 0.0001) for younger ages, and opioid days' supply was higher for older ages. CONCLUSIONS: Texas Medicaid SCD patients had low hydroxyurea utilization and adherence across all age groups. Interventions to increase the use of hydroxyurea and newer preventative therapies could result in better management of SCD-related complications and reduce the frequency of pain crises, which may reduce the need for opioid use.

Use of patient assessment skills in advanced pharmacy practice experiences.

INTRODUCTION: Pharmacy programs are required to teach patient assessment (PA) skills. However, pharmacist workforce survey data indicates that limited opportunities exist for students to practice PA skills in real-world settings. The study objectives were to (1) assess how often PA skills are utilized by fourth-year pharmacy (P4) students on advanced pharmacy practice experiences (APPEs), (2) determine perceived competence in performing PA skills, and (3) examine relationships between grade-point average or post-graduation plans and the number of skills performed and between skill use frequency and self-reported competency. METHODS: P4 students completed a questionnaire assessing 13 PA skills. Respondents performing a skill indicated frequency of use and rated their competence using a 5-point scale. Descriptive and bivariate statistics were reported. RESULTS: The response rate was 81%. Measuring blood pressure (BP) (76%) and evaluating metered-dose inhaler (MDI) technique (74%) were most commonly performed. Peak-flow meter evaluation (6%) and lymph node examination (2%) were least commonly performed. Measuring BP and evaluating MDI technique had the highest competency ratings (4.6 + 0.7 for both). Lung (3.4 + 0.7) and heart (2.8 + 1) auscultation had the lowest competency ratings. Positive correlations were found between the frequency of skill use and self-reported competence for assessing MDI technique, peripheral pulses, and peripheral edema. No other findings were significant. CONCLUSIONS: P4 students reported high perceived competency for PA skills performed frequently during APPEs. Preceptor education, requiring skill use, and encouraging students to proactively identify situations to use skills could increase opportunities for use of PA skills.

Prevalence of and Factors Associated with Gabapentinoid Use and Misuse Among Texas Medicaid Recipients.

BACKGROUND AND OBJECTIVES: Gabapentin and pregabalin have been considered relatively safe opioid-sparing adjuncts for pain management. However, rising prescribing trends, presence of gabapentinoids in opioid-related overdoses, and the growing body of evidence regarding gabapentinoid misuse and abuse, have caused gabapentinoids to emerge as a drug class of public health concern. This study aimed to assess the prevalence of, and factors associated with gabapentinoid use and misuse. METHODS: This retrospective study of Texas Medicaid data from 1/1/2012 to 30/8/2016 included patients aged 18-63 years at index date, with ≥ 1 gabapentinoid prescription, and continuously enrolled 6 months pre-index and 12 months post-index. Gabapentinoid misuse was defined as ≥ 3 claims exceeding daily doses of 3600 mg for gabapentin and 600 mg for pregabalin. Age, gender, concurrent opioid use, neuropathic pain diagnoses and gabapentinoid type were independent variables. Descriptive and inferential statistics were used. RESULTS: Of included subjects (N = 39,000), 0.2% (N = 81) met study criteria for gabapentinoid misuse. Overall, the majority (76.4%) of gabapentinoid users were aged 41-63 years with a mean ± SD age of 48.2 ± 10.7 years. Those patients meeting the study criteria for gabapentinoid misuse were significantly younger (45.1 ± 11.0 vs 48.2 ± 10.7, p = 0.0084). Majority of the study sample was female (68.1%). However, a significantly higher proportion of males met the study criteria for gabapentinoid misuse compared to females (0.3% vs 0.2%, p = 0.0079). Approximately one-half (51.9%) of the study sample had neuropathic pain, and gabapentinoid misuse was significantly higher in neuropathic pain patients compared to those without neuropathic pain (0.3% vs 0.1%, p = 0.0078). Over three-quarters (77.4%) of patients were using gabapentin; however, gabapentinoid misuse was significantly higher among pregabalin users (0.4% vs 0.2%, p = 0.0003). Approximately 20% (17.3%) of gabapentinoid users had ≥ 90 days of concurrent opioid use. However, there was no significant difference in gabapentinoid misuse among patients with concurrent opioid use compared to patients without (0.3% vs 0.2%, p = 0.1440). Factors significantly associated with misuse included: male sex (odds ratio [OR] 0.486; 95% confidence interval [CI] 0.313-0.756; p = 0.0013); neuropathic pain (OR 2.065; 95% CI 1.289-3.308; p = 0.0026); and pregabalin versus gabapentin use (OR 2.337, 95% CI 1.492-3.661; p = 0.0002). Concurrent opioid use was not significantly associated with gabapentinoid misuse (OR 1.542, 95% CI 0.920-2.586; p = 0.1006). CONCLUSION: Prevalence of gabapentinoid misuse was low (0.2%) among Texas Medicaid recipients. Younger age, male gender, neuropathic pain diagnosis and pregabalin use were significantly associated with higher levels of gabapentinoid misuse.

Impact of emergency department opioid use on future health resource utilization among patients with migraine.

OBJECTIVE: The purpose of this study was to evaluate the subsequent health resource utilization (HRU) between patients with migraine who received opioid medications at their emergency department (ED) visits ("opioid recipients") versus patients with migraine who did not receive opioid medications at their ED visits ("non-recipients"). BACKGROUND: Previous studies have found that opioid use is common among patients with migraine at emergency settings. Medication overuse, especially the use of opioids, is associated with migraine progression, which can ultimately lead to substantial health resource use and costs. There is limited evidence on opioid use specifically in emergency settings and its impact on future HRU among people with migraine. METHOD: This retrospective cohort study used electronic health record data from the Baylor Scott & White Health between December 2013 and April 2017. Adult patients who had at least 6 months of continuous enrollment before (baseline or pre-index) and after (follow-up) the first date they had an ED visit with a diagnosis of migraine (defined as index date) were enrolled in the study. Opioid use and HRU during follow-up period between opioid recipients and non-recipients were summarized and compared. RESULTS: A total of 788 patients met the eligibility criteria and were included in this study. During the 6-month follow-up period, compared to patients with migraine who were non-recipients at their index ED visits, opioid recipients had significantly more all-cause (3.6 [SD = 6.3] vs. 1.9 [SD = 4.8], p < 0.0001) and migraine-related (1.6 [SD = 4.2] vs. 0.6 [SD = 2.1], p < 0.0001) opioid prescriptions (RXs), and more all-cause (2.6 [SD = 4.3] vs. 1.6 [SD = 2.6], p = 0.002) and migraine-related (0.6 [SD = 1.4] vs. 0.3 [SD = 0.8], p = 0.001) ED visits. In addition, opioid recipients had higher risk of future migraine-related ED visits controlling for covariates (HR = 1.49, 95% CI = 1.09-2.03, p = 0.013). Factors that were significantly (p < 0.05) related to future migraine-related ED visits include previous opioid use (HR = 2.12, 95% CI = 1.24-3.65, p = 0.007), previous ED visits (HR = 2.38, 95% CI = 1.23-4.58, p = 0.010), hypertension (HR = 1.46, 95% CI = 1.07-2.00, p = 0.017), age between 45 and 64 years (HR = 0.68, 95% CI = 0.48-0.97, p = 0.033), female sex (HR = 1.82, 95% CI = 1.12-2.86, p = 0.015), and tobacco use disorder (HR = 1.45, 95% CI = 1.07-1.97, p = 0.017). Sub-analyses were restricted to the group of patients who were opioid naïve at baseline (n = 274, defined as having ≤1 opioid RXs during the 6-month pre-index period). Patients who were baseline opioid naïve but received opioids during their index ED visits were more likely to have future migraine-related ED visits compared to patients who were baseline opioid naïve and did not receive any opioids during their index ED visits, controlling for covariates (HR = 2.90, 95% CI = 1.54-5.46, p = 0.001). CONCLUSION: Opioid use among patients with migraine presenting to the ED is associated with increased future HRU, which highlights the need for optimizing migraine management in emergency settings.

Use of a claims-based algorithm to estimate disease severity in the multiple sclerosis Medicare population.

BACKGROUND/OBJECTIVE: To compare algorithm determined disease severity, risk of multiple sclerosis (MS) relapse, and MS-related hospitalization between the age-eligible and disability-eligible MS Medicare populations. METHODS: Using the Humana claims dataset (2013 - 2015), patients were divided into Medicare age-eligible and disability-eligible groups. A previously developed algorithm, which used MS symptoms and healthcare utilization to categorize MS disease severity into three groups (low, moderate, high) at baseline was employed. Flexible parametric and Cox proportional hazard models were used to estimate the risk for MS relapses and MS-related hospitalizations among the MS disease severity groups and the two eligibility cohorts in the follow-up period. RESULTS: Of the overall sample (N = 6,559), the majority (N = 4,813, 73.4%) were disability-eligible and in the low disease severity group (N = 4,468, 68.1%). In 10 of 16 disease severity algorithm predictors, the prevalence of these predictors was significantly (p<0.001) higher in the disability-eligible group compared to the age-eligible group. Survival analyses revealed that the disability-eligible group had a significantly higher risk for follow-up MS relapses and follow-up MS-related hospitalizations (HR = 1.79 [CI 1.54 - 2.08] and HR = 1.38 [CI 1.11-1.72], respectively) compared to those in the age-eligible group. When both eligibility and disease severity were considered in the model increases in hazard ratios corresponded generally to increases in disease severity. However, the type of Medicare eligibility does not appear to have a clear pattern across MS disease severity groups for either MS relapse or hospitalizations, CONCLUSION: The disability-eligible Medicare population had a significantly higher prevalence of MS comorbidities and higher MS severity scores at baseline. In addition, they had a higher risk for MS-related relapses and MS-related hospitalizations in the follow-up period. It is important to account for disability status when assessing disease severity and healthcare utilization.

Efavirenz versus Protease Inhibitors in Patients with HIV: A Systematic Review and Meta-Analysis

Efavirenz- and protease inhibitor (PI)-based regimens remain viable options across the globe. We conducted a meta-analysis to compare the effectiveness of efavirenz-based regimens relative to PI-based regimens. EMBASE, PubMed, Cochrane, and clinicaltrials.gov were searched for randomized controlled trials conducted between 1987 and 2018 comparing efavirenz- with PI-based regimens. This was followed by title, abstract, and full-text screens. The quality of selected studies was assessed using the Cochrane risk of bias tool. Meta-analysis of the odds of virological suppression was conducted using the robust variance estimation approach. Fifteen studies met the inclusion criteria and totaled 6712 patients (efavirenz arm = 3339; PI arm = 3373), of which 1610 (24.0%) were females. Follow-up ranged from 24 to 144 weeks. Mean/median age ranged from 33 to 44 years. Mean/median baseline CD4 count ranged from 32 to 557 cells/mL while mean/median baseline viral load ranged from log10 4.5 to log10 5.5 copies/mL. Meta-analysis showed that patients receiving efavirenz-based regimens had 37% higher odds of virological suppression compared to PI-based regimens (odds ratio = 1.37, 95% confidence interval = 1.06-1.77, p = 0.02). The Egger test suggested the presence of publication bias (B = 0.927, t = 2.214, p = 0.033). The main threat to the quality of evidence was attrition bias. Regarding virological suppression, efavirenzbased regimens were more effective than PI-based regimens and, therefore, might be ideal for the management of treatment naïve patients with HIV in settings where NNRTIs and PIs are used.

Gender and ethnic differences in rates of immune reconstitution, AIDS diagnosis, and survival.

In this work, we use 2011-2013 Texas HIV surveillance data (N=2,175) and apply hierarchical linear and Cox regression modeling to characterize the association of gender and race/ethnicity with rate of immune recovery and determine whether immune recovery contributes to gender and racial/ethnic disparities in AIDS diagnosis and survival. The associations between gender and rate of immune recovery and between race/ethnicity and rate of immune recovery were not statistically significant (p > 0.05). In the multivariate survival analyses, there was no statistically significant association between gender and AIDS diagnosis (Adjusted Hazard Ratio (AHR) = 1.06, p = 0.61, 95%=0.85-1.32) and between race/ethnicity and AIDS diagnosis (Blacks vs Whites: AHR = 1.10, p = 0.24, 95% CI = 0.94-1.30; Hispanics vs Whites: AHR = 1.06, p = 0.46, 95% CI = 0.91-1.24). Similarly, there were no statistically significant associations with death (males vs females: AHR = 0.88, p = 0.73, 95% CI = 0.43-1.81; Blacks vs Whites: AHR = 0.68 p = 0.25, 95% CI = 0.36-1.30; Hispanics vs Whites: AHR = 0.96, p = 0.88, 95% CI = 0.55-1.67). However, the direction of the point estimates were in the reverse direction when compared to the rate of immune recovery or the AIDS diagnosis models. Our findings suggest that differences in rate of immune recovery may better explain disparities in AIDS diagnosis than disparities in survival. Future studies with longer follow-up may potentially generate statistically significant results.

Identifying subgroups within at-risk populations that drive late HIV diagnosis in a Southern U.S. state.

We aimed to identify subgroups within age, racial/ethnic, and transmission categories that drive increased risk for late HIV diagnosis (LHD).A 1996-2013 retrospective study of HIV-diagnosed individuals (N = 77,844) was conducted. The proportion of individuals with LHD (AIDS diagnosis within 365 days of HIV diagnosis) was determined, stratified by age, race/ethnicity, and transmission category. Logistic regression with interaction terms was used to identify groups/subgroups at risk for LHD during 1996-2001, 2002-2007, and 2008-2013.Respectively, 78%, 27%, 38%, and 31% were male, White, Black, and Hispanic. Overall, 39% had LHD with a 6.7% reduction for each year increase (OR = 0.93, 95% CI = 0.93-0.94, p < 0.01). Older age was significantly associated with increased odds of LHD (OR range = 1.90-4.55). Compared to their White counterparts, all Hispanic transmission categories (OR range = 1.31-2.58) and only Black female heterosexuals and men who have sex with men (MSM) (OR range = 1.14-1.33) had significantly higher odds of LHD during 1996-2001 and/or 2002-2007. Significance was limited to Hispanic MSM (all age categories), MSM/IDUs (30-59 years), and heterosexuals (18-29 years) and Black MSM (30-39 years) during 2008-2013.Older individuals and Hispanics (driven by MSM) are at increased risk for LHD. HIV testing interventions directed at seniors and Hispanic MSM can further reduce rates of LHD.

Patterns and predictors of opioid use among migraine patients at emergency departments: A retrospective database analysis.

OBJECTIVES: To compare medication use and health resource utilization between migraineurs with evidence of opioid use at emergency department visit versus no opioid use at emergency department visit, and to examine predictors of opioid use among migraineurs at emergency department visits. METHODS: This was a retrospective study using REACHnet electronic health records (December 2013 to April 2017) from Baylor Scott & White Health Plan. The index date was defined as the first migraine-related emergency department visit after ≥6 months of enrollment. Adult patients with a migraine diagnosis and ≥6 months of continuous enrollment before and after their index dates were included. Descriptive statistics and bivariate analyses were used to compare medication use and health resource utilization between opioid users and non-opioid users. Multivariable logistic regression was used to examine predictors of opioid use at emergency department visits. RESULTS: A total of 788 migraineurs met eligibility criteria. Over one-third (n = 283, 35.9%) received ≥1 opioid medication during their index date emergency department visit. Morphine (n = 103, 13.1%) and hydromorphone (n = 85, 10.8%) were the most frequently used opioids. Opioid users had more hospitalizations and emergency department visits during their pre-index period (both p < 0.05). Significant (p < 0.05) predictors of opioid use at emergency department visits included past migraine-related opioid use (2-4 prescriptions, Odds Ratio = 1.66; 5-9 prescriptions, Odds Ratio = 2.12; ≥10 prescriptions, Odds Ratio = 4.43), past non-migraine-related opioid use (≥10 prescriptions, Odds Ratio = 1.93), past emergency department visits (1-3 visits, Odds Ratio = 1.84), age (45-64 years, Odds Ratio = 1.45), and sleep disorder (Odds Ratio = 1.43), controlling for covariates. CONCLUSION: Opioids were commonly given to migraineurs at emergency departments. Previous opioid use, health resource utilization, age, and specific comorbidities might be used to identify migraineurs with a high risk of opioid use.

Association of depression with adherence to breast cancer screening among women aged 50 to 74 years in the United States.

RATIONALE, AIMS, AND OBJECTIVES: Previous research has shown inconsistent results regarding the association of depression and screening mammography use behaviours. This study aimed to assess the relationship between women's depression and mammography adherence. METHODS: This cross-sectional study used data from the 2016 Behavioural Risk Factor Surveillance System and employed the Health Belief Model (HBM). The primary independent variable was the presence of depression. The dependent variable was adherence to biennial screening mammography based on the US Preventive Services Task Force guidelines. Demographic characteristics and HBM constructs were included as covariates. Univariate and multivariate logistic regressions were used. RESULTS: A total of 139 550 women were included (weighted n = 48 712 531). Among them, 23.1% reported the presence of depression (n = 32 247). The unadjusted odds ratio (OR) for mammography use in women with depression was 0.85 (95% confidence interval [CI], 0.80-0.91, P < .001) compared with women without depression, and the probability of mammography use was significantly lower in women with depression (76.3%; 95% CI, 75.4-77.3) compared with women without depression (79.1%; 95% CI, 78.5-79.6). However, the adjusted OR was not statistically significant when controlling for demographic and HBM characteristics (1.02; 95% CI, 0.93-1.11, P = .698), and the probabilities of mammography use were similar between women with depression (80.1%; 95% CI, 79.0-81.3) and without depression (79.9%; 95% CI, 79.2-80.6). CONCLUSIONS: Depression itself was related to nonadherence with mammography screening guidelines. However, after controlling for demographic and HBM characteristics, depression was not associated with adherence with mammography screening guidelines.

Association between quality-of-care indicators for HIV infection and healthcare resource utilization and costs.

OBJECTIVES: Multiple care quality indicators for HIV infection exist but few studies examine their impact on health outcomes. This study assessed which HIV care quality indicators were associated with healthcare resource utilization and costs. DESIGN: Retrospective analysis of Texas Medicaid claims data (01 January 2012 to 31 September 2016). METHODS: Included patients had at least two HIV-related medical claims during the identification period (01 July 2012 to 31 August 2014) (index = date of first HIV claim), were 18-62 years at index, and were continuously enrolled in the 6-month pre-index and 1-year post-index periods. Dependent variables included emergency department (ED) visits, inpatient hospitalizations, prescription count, and all-cause healthcare costs. Independent variables included CD4 cell count monitoring, syphilis, chlamydia, gonorrhea, hepatitis B, hepatitis C, and tuberculosis screenings, influenza and pneumococcal vaccinations, retention in care, and HAART initiation. Covariates included age, chronic hepatitis C virus infection, AIDS diagnosis, sex, and baseline healthcare cost. The study objective was addressed using generalized linear modeling. RESULTS: CD4 cell count monitoring and HAART initiation were significantly associated with reduced emergency department visits (P < 0.0001 for each). Influenza vaccination was significantly associated with reduced inpatient hospitalization (P < 0.0001). CD4 cell count monitoring (P < 0.0001), TB screening (P = 0.0006), influenza vaccination (P < 0.0001), and HAART initiation (P < 0.0001) were significantly associated with increase prescription claims. CD4 cell count monitoring, TB screening, and HAART initiation (P < 0.0001 for each) were significantly associated with all-cause healthcare costs. CONCLUSION: HAART may reduce use of emergency care services as early as 1 year following initiation.

Comprehensive health management pharmacist-delivered model: impact on healthcare utilization and costs.

OBJECTIVES: To (1) examine the impact of the Comprehensive Health Management Patient Service (CHaMPS) on unplanned hospital admissions and emergency department (ED) visits in patients with chronic conditions, (2) describe the number and type of pharmacist interventions, and (3) determine the cost savings of CHaMPS. STUDY DESIGN: Retrospective, cross-sectional design with a matched comparator group. METHODS: CHaMPS integrated pharmacists within family medicine clinics to optimize medication use among patients with chronic conditions. Outcomes were the change in unplanned hospital admissions and ED visits from baseline to 180- and 365-day postintervention periods between the CHaMPS and propensity-matched comparator groups. Descriptive, bivariate (t tests and McNemar tests), and multivariate (general linear models) statistical analyses were used. Pharmacist interventions are reported and a cost-benefit analysis was conducted. RESULTS: A total of 624 patients (312 in the CHaMPS group and 312 in the comparator group) were included. Unplanned hospital admissions decreased in the CHaMPS group and increased in the comparator group (not significant). ED visits remained stable in the CHaMPS group but increased significantly in the comparator group, resulting in a significant mean change in ED visits between the groups at the 180- and 365-day postintervention periods (P = .03 for both periods). Pharmacists provided a total of 5705 medication-related problem, education, and medication reconciliation interventions (18.3 per patient). The benefit-cost ratio ranged from 2.1:1 to 2.6:1. CONCLUSIONS: CHaMPS achieved its goals by demonstrating a positive impact on ED visits and a benefit-cost ratio greater than 1.0. The cost savings of the embedded pharmacist model are most beneficial from a payer perspective or an accountable care organization approach to healthcare.
