Factors Associated with Statin Discontinuation Following Metabolic and Bariatric Surgery: A Retrospective Analysis of 2012-2021 Electronic Medical Records Network Data.

BACKGROUND: Bariatric surgery has been shown to improve hyperlipidemia, decreasing the need for statin medications. Although maintaining statin therapy post-surgery for those with a history of atherosclerotic cardiovascular disease (ASCVD) is advised, it is uncertain if discontinuation risks differ between those with and without ASCVD history. AIM: The study aims to analyze the rate and reasons for statin cessation post-bariatric surgery in the US using real-world data. METHODS: Using the TriNetX electronic medical records network from 2012 to 2021, the study involved patients aged 18 or older on statins at the time of bariatric surgery. They were categorized into primary and secondary prevention groups based on prior ASCVD. Statin discontinuation was defined as a 90-day gap post the last statin dosage. The Cox model assessed factors influencing statin cessation. RESULTS: Seven hundred and thirty-three statin users undergoing bariatric surgery were identified, with 564 (77%) in primary prevention. Six months post-surgery, 48% of primary prevention patients and 34.5% of secondary ones stopped statins. Primary prevention patients had a 30% higher likelihood of cessation compared to secondary prevention (hazard ratio, 1.30; 95% CI, 1.06-1.60) as shown by multivariable analysis. CONCLUSIONS: Post-bariatric surgery, primary prevention patients are more likely to discontinue statins than secondary prevention patients.

Metabolic and Bariatric Surgery Utilization Trends in the United States: Evidence From 2012 to 2021 National Electronic Medical Records Network.

Background: Bariatric surgery has evolved over the past 2 decades yet assessing trends of bariatric surgery utilization in the growing eligible population is lacking. Aim: This study aimed to update the trends in bariatric surgery utilization, changes in types of procedures performed, and the characteristics of patients who underwent bariatric surgery in the United States, using real-world data. Method: This retrospective descriptive observational study was conducted using the TriNetX, a federated electronic medical records network from 2012 to 2021, for adult patients 18 years old or older who had bariatric surgery. Descriptive statistical analysis was conducted to assess patients' demographics and characteristics. Annual secular trend analyses were conducted for the annual rate of bariatric surgery, and the specific procedural types and proportions of laparoscopic surgeries. Results: A steady increase in the number of procedures performed in the United States over the first 6 years of the study, a plateau for the following 2 years, and then a decline in 2020 and 2021 (during the coronavirus disease 2019 pandemic). The annual rate of bariatric surgery was lowest in 2012 at 59.2 and highest in 2018 at 79.6 surgeries per 100,000 adults. During the study period, 96.2% to 98.8% of procedures performed annually were conducted laparoscopically as opposed to the open technique. Beginning in 2012, the Roux-en-Y gastric bypass (RYGB) procedure fell to represent only 17.1% of cases in 2018, along with a sharp decline in the adjustable gastric band (AGB) procedure, replaced by a sharp increase in the sleeve gastrectomy (SG) procedure to represent over 74% of cases in 2018. Conclusions: Bariatric surgery utilization in the United States showed a moderate decline in the number of RYGB procedures, which was offset by a substantial increase in the number of SG procedures and a precipitous drop in the annual number of AGB procedures.

Safety reporting of Essure medical device: a qualitative and quantitative assessment on the FDA manufacturer and user facility device experience database in 2018.

Background: There have been numerous cases of adverse events since the introduction of Essure medical devices for sterilization in 2002. This study analyzed the safety event reports of the Essure reported in the Manufacturer and User Facility Device Experience (MAUDE). Methods: A retrospective analysis examined the MAUDE reports between Jan-1, 2018, and Oct-31, 2018 and focused on safety reports related to the Essure device. Safety reports were categorized and analyzed by their event type, device problem, patients' symptoms and the level of harm. Of this study cohort, 10% of samples were randomly selected for quantitative analyses. Thematic analysis was conducted for reports included death cases. Results: A total of 4,994 eligible reports were analyzed. There were ten reports associated with individuals' deaths, and the main themes of safety reports from qualitative analysis were pains, bleeding, surgery, migraine, and infection. Quantitative analysis of 500 randomly selected samples showed that 98% of adverse event reports were associated with different injuries such as surgery, pain, bleeding, hysterectomy, and menorrhagia. Additionally, more than 90% of reports were submitted by the manufacturer. Conclusion: These findings indicated several safety issues of Essure. More meaningful pre- and post-marketing surveillance and regulation are warranted in the medical device market to ensure safety and effectiveness, including investigating complaints, promptly sharing relevant information with regulators and users, and implementing corrective actions.

The Utilization, Expenditure, and Price of Angiotensin-Converting Enzyme Inhibitors and Angiotensin Receptor Blockers in the US Medicaid Programs: Trends Over a 31 Year Period.

BACKGROUND: Angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) are used for several indications including hypertension. Our aim is to evaluate the utilization, expenditure, and drug price of ACEIs and ARBs in the US Medicaid population. METHODS: A retrospective descriptive trend analysis was conducted using Medicaid State Drug Utilization outpatient pharmacy summary files managed by the Centers for Medicare and Medicaid Services from 1991 to 2021. Study drugs included ACEIs (e.g., captopril) and ARBs (e.g., losartan). Annual reimbursement and utilization were calculated for both classes. The average reimbursement per prescription was calculated as a proxy for drug prices. Market share competition between ACEIs and ARBs was analyzed over time. RESULTS: ACEI and ARB utilization rose by 25% from 1991 to 2021. Brand ACEIs utilization peaked in 2002 with 28 million prescriptions while brand ARBs utilization continued to increase until 2005 with over 23 million prescriptions. However, generic products took the lead and exceeded brand ACEI and ARB utilization in 2006 and 2012 respectively. Medicaid spent over $ 33.7 billion on ACEIs and ARBs over 31-year. Brand ACEIs and ARBs average prices increased sharply to $8,104 and $6,908 respectively in 2021. The total prescription market share for ACEIs was 68% compared to 32% of ARBs over the entire study. CONCLUSION: ACEIs and ARBs utilization increased over the last 31 years. Brand utilization switched over to generic resulting in less reimbursement. The average prices of brand ACEIs and ARBs continue to increase even after generics were introduced to the market.

The effect of polypharmacy on quality of life in adult patients with nonalcoholic fatty liver disease in the United States.

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) is a significant epidemiological problem with rising prevalence. Due to limited literature, the objective of this study is to examine the association between polypharmacy and health-related quality of life (QoL) in NAFLD adult patients. METHODS: A retrospective observational study design was conducted to analyze health data collected by Steatohepatitis Clinical Research Network (NASH CRN). Patients were classified as receiving a polypharmacy therapy with five or more medications in their first screening visit. QoL was measured using the Short Form 36 (SF-36) instrument. Each patient self-reported the SF-36 form during the screening visit was compared between polypharmacy and non-polypharmacy groups using Wilcoxon Rank Sum test. Multivariable generalized linear models and multinomial logistic regression were performed to examine each predictor and its effect on QoL. RESULTS: Data included 1067 NAFLD adult patients; 834 patients used polypharmacy. The mean age was 48.64 years, and most patients were female (62%). Comparing NAFLD patients without steatohepatitis, borderline NASH, and definite NASH, the non-polypharmacy group had a significantly higher QoL than the polypharmacy group in Physical Component Summary (PCS) (86.25 vs 66.88, 85 vs 67.5, and 79.375 vs 63.12, respectively, all p < 0.01) and Mental Component Summary (MCS) (83.5 vs 73.38, 78.75 vs 67.62, and 78.75 vs 70.65, respectively, all p < 0.01). DISCUSSION AND CONCLUSION: Adults with NAFLD and polypharmacy have lower QoL than adults with NAFLD and non-polypharmacy. Number of medications had a significant negative impact on PCS, MCS, and all SF-36 domains except mental health, role physical limitation and role emotional limitation domains. Other factors that affect QoL negatively in NAFLD adult patients are female gender, obesity, diabetes, depression, and unemployment. Higher income had favorable effect on QoL.

Off-label medication use in rare pediatric diseases in the United States.

Many pediatric patients with rare diseases use drugs off-label due to limited data in pediatric patients. Off-label treatment remains an important public health issue for neonates, infants, children, and adolescents, especially for pediatric patients with rare diseases. For patients with rare diseases, the majority of medications have no or limited information in labelling for pediatric use. Children present unique considerations in clinical trials due to ethical and clinical concerns, which have limited and even discouraged testing of drugs in the pediatric population. Numerous legislative measures have been enacted to address barriers in pediatric drug testing. This research reviewed off-label medication use in rare pediatric diseases, evaluated recent medication uses in pediatric clinical practice, discussed key regulations for rare pediatric diseases, and summarized recent drug approvals for rare pediatric diseases. This study demonstrates the ongoing medical need for newly approved medications to treat pediatric rare diseases and revealed the positive impact of regulations from the Orphan Drug Act of 1983 to the Research to Accelerate Cures and Equity (RACE) for Children Act on drug development and off-label medication practice in rare pediatric disease management. This article provides informative historical background and current considerations of off-label use of medications in neonates, infants, children, and adolescents with rare diseases.

Comparative effectiveness and persistence of TNFi and non-TNFi in juvenile idiopathic arthritis: a large paediatric rheumatology centre in the USA.

OBJECTIVE: To evaluate the persistence and effectiveness of TNF inhibitors (TNFi) vs non-TNFi among newly diagnosed JIA patients after initiation of biologic DMARD (bDMARD). METHODS: Using longitudinal patient-level data extracted from electronic medical records in a large Midwestern paediatric hospital from 2009 to 2018, we identified JIA patients initiating TNFi and non-TNFi treatment. Treatment effectiveness was assessed based on disease activity. Inverse probability of treatment weighting of propensity score was used to estimate the treatment effectiveness and Kaplan-Meier analyses were conducted to assess persistence. RESULTS: Of 667 JIA patients, most (92.0%) were prescribed one of the class of TNFi as their initial biologic treatment. Etanercept was the most frequently prescribed (67.1%) treatment, followed by adalimumab (27.5%). Only around 5% of patients were prescribed off-label bDMARDs as their first-course treatment; however, >20% were prescribed off-label biologics as their second-course therapy. Some 7.2% of patients received four or more bDMARDs. The median persistence of the first-course bDMARD is 320 days, with TNFi being significantly longer than the non-TNFi (395 vs 320 days, P = 0.010). The clinical Juvenile Disease Activity Score (cJADAS) reduction of TNFi users (6.6, 95% CI 5.7, 7.5) was significant greater compared with non-TNFi users (3.0, 95% CI 1.5, 4.6, P < 0.0001) at 6-month follow-up visit. CONCLUSION: Persistence was significantly longer among patients initiating TNFi as their first biologic therapy than those receiving non-TNFi. Patients receiving TNF therapy had significant greater reduction of cJADAS at the 6-month follow-up visit compared with patients in the non-TNF cohort.

Prescribing Patterns and Impact of Factors Associated with Time to Initial Biologic Therapy among Children with Non-systemic Juvenile Idiopathic Arthritis.

OBJECTIVE: The aim of this study was to examine patterns of initial prescriptions, investigate time to initiation of biologic disease-modifying anti-rheumatic drugs (bDMARDs), and evaluate the impact of clinical and other baseline factors associated with the time to first bDMARD in treating children with newly diagnosed non-systemic juvenile idiopathic arthritis (JIA). METHODS: Using longitudinal patient-level data extracted from electronic medical records (EMR) in a large Midwestern pediatric hospital from 2009 to 2018, the initial prescriptions and prescribing patterns of bDMARDs, conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs), non-steroidal anti-inflammatory drugs (NSAIDs) and glucocorticoids within 3 months of JIA diagnosis were examined. Kaplan-Meier analyses were performed to assess time to initiation of bDMARDs. Cox proportional hazard models were used to identify factors associated with time to first bDMARD. RESULTS: Of 821 children, the proportion of patients with initial csDMARDs increased from 45.3% in 2009 to 60.3% in 2018. Around 57.5% of polyarthritis rheumatoid factor-positive (Poly RF+) patients and 43.2% of polyarthritis rheumatoid factor-negative (Poly RF-) patients received a bDMARD therapy within 3 months of diagnosis, 14.4% as monotherapy and 28.3% in combination with a csDMARD. Among patients who received combination therapy, combination of methotrexate with adalimumab increased from 16.7% in 2009 to 40% in 2018. The proportion of patients treated with adalimumab gradually increased and passed etanercept in 2016. The predictors of earlier initiation of biologic therapy were JIA category enthesitis-related arthritis (ERA) [hazard ratio (HR) vs persistent oligoarthritis 4.82; p < 0.0001], psoriatic arthritis (PsA) (HR 2.46; p = 0.0002), or Poly RF- (HR 2.43; p = 0.0002); the number of joints with limited range of motion (HR 1.02; p = 0.0222), and erythrocyte sedimentation rate (ESR, HR 1.01; p = 0.0033). CONCLUSIONS: There was a substantial increase in the proportion of patients receiving the combination of methotrexate and adalimumab among patients receiving combination therapy. Adalimumab overtook etanercept as the most frequently prescribed bDMARD. Multiple factors affect the time to biologic initiation, including the number of joints with limited range of motion, ESR, and JIA category.

Correlation of the Pharmacy Curriculum Outcomes Assessment and Selected Pre-pharmacy and Pharmacy Performance Variables.

Objective. To identify the correlation between the Pharmacy Curriculum Outcomes Assessment (PCOA) and pre-pharmacy and pharmacy performance variables. Methods. Four years of PCOA data (2012-2015) were analyzed for students taking the assessment in the third professional year (P3). Using the Pearson correlation coefficient, data was correlated to a series of performance variables: pre-pharmacy grade point average (GPA), pre-pharmacy science GPA (pre-pharmacy science courses only), Pharmacy College Admission Test (PCAT) composite score, P3 pre-advanced pharmacy practice experience (APPE) GPA and the North American Pharmacist Licensure Examination (NAPLEX). Scores that were correlated at r ≥ 0.30 were added to a multivariate linear regression model to compare their unique contributions. Results. There was a moderate correlation between PCOA and PCAT (r=0.60), P3 pre-APPE GPA (r=0.60) and the NAPLEX (r=0.64). The multivariate regression analysis explained 60% of the variance of the total PCOA score, with PCAT making the largest unique contribution. Conclusion. The PCOA was moderately to strongly correlated to the pre-APPE GPA, thus providing an acceptable assessment of student learning. The PCOA was also moderately to strongly correlated to the NAPLEX, making it a useful tool in predicting performance and identifying students in need of further remediation before the NAPLEX.

Trends in Utilization, Spending, and Prices of Smoking-Cessation Medications in Medicaid Programs: 25 Years Empirical Data Analysis, 1991-2015.

BACKGROUND: Smoking remains the single largest preventable cause of death and disease. Smoking-cessation medications provide patients a multitude of benefits and can prevent certain diseases, including some cancers. Because of the limited amount of studies on smoking-cessation medications, we wanted to find general trends about the use of these medications. OBJECTIVE: To examine trends in the utilization, pharmacy reimbursement, and prices of smoking-cessation medications and nicotine replacement therapy in the US Medicaid-covered population. METHODS: Using national summary files for outpatient drug utilization and expenditure, we extracted data on smoking-cessation medications from the Centers for Medicare & Medicaid Services in the 25 years from January 1991 through June 2015. We conducted a retrospective drug utilization study to examine the annual (or quarterly) trends of the number of prescriptions, reimbursement expenditures, and the prices of smoking-cessation medications. The study drugs included varenicline (Chantix), bupropion (Zyban), and nicotine. We calculated per-prescription pharmacy reimbursement, which was used as a proxy for drug price, as the total quarterly expenditure for the drug, divided by the total number of prescriptions. All expenditures were inflated to 2015 US dollars using the medical services component of the Consumer Price Index. RESULTS: The total number of prescriptions for smoking-cessation medications increased rapidly from 46,396 in 1991 to 942,562 in 2014, an increase of more than 1931%. During the same period, the total pharmacy reimbursement for smoking-cessation medications in Medicaid increased by 3562%, from approximately $2.8 million in 1991 to approximately $101 million in 2014. The use of the nonnicotine prescription drugs varenicline and bupropion also increased rapidly, with a high cost expenditure. The price per nonnicotine prescription drug increased over time, ranging from approximately $169 for bupropion to approximately $251 for varenicline in 2015. CONCLUSIONS: The substantial increase in nonnicotine prescription drugs and nicotine replacement therapy between 2007 and 2015 may be attributed to smoking-cessation participants nationwide. Cost-containment policies might have inadvertently prevented Medicaid-covered smokers from obtaining appropriate pharmacotherapy.

Utilization, Spending, and Price Trends for Quinolones in the US Medicaid Programs: 25 Years' Experience 1991-2015.

BACKGROUND: Given that the quinolones is one of the antibacterial classes most frequently used to treat patients with bacterial infections in the United States, any change in prescribing patterns of quinolones will impact Medicaid medical expenditures. OBJECTIVES: This study was undertaken to examine trends in utilization, reimbursement, and prices of quinolone antibacterials for the US Medicaid population. METHODS: The publicly available Medicaid State Drug Utilization outpatient pharmacy files were used for this study. Quarterly and annual prescription counts and reimbursement amounts were calculated for each of the quinolones reimbursed by Medicaid from quarter 1, 1991 through quarter 2, 2015. Average per-prescription reimbursement, as a proxy for drug price, was calculated as the drug reimbursement divided by the number of prescriptions. RESULTS: The total annual number of quinolone prescriptions increased 402%, from 247,395 in the first quarter of 1991 to 1.2 million in the second quarter of 2015, peaking at 1.3 million in the first quarter of 2005. Similarly, the total reimbursement for quinolone agents increased by 245.5% over the same period. More than 80% of quinolone prescriptions reimbursed by Medicaid were for the second-generation agent, ciprofloxacin, and the third-generation agent, levofloxacin. The average payment per prescription for quinolones increased from US$43.8 in the first quarter of 1991 to US$87.6 in the second quarter of 2015. CONCLUSIONS: A substantial rise in Medicaid expenditures on quinolones was observed during the 25-year study period, which was mainly because of rising utilization. Therefore, there is a need for additional research that has access to clinically relevant data with which to measure the rate of inappropriate quinolone use among the Medicaid population and associated clinical outcomes and healthcare costs.

Antithrombotic Therapy and Direct Medical Costs in Patients with Acute Coronary Syndrome in Shanghai, China.

BACKGROUND: Acute coronary syndrome (ACS) is a leading cause of morbidity and mortality worldwide. OBJECTIVES: To describe patient profile, treatment patterns, and disease burden for patients with ACS. METHODS: A retrospective descriptive cohort study was conducted. Data were obtained from electronic medical records from seven Shanghai medical centers. Patients with at least one primary diagnosis of ACS from 2006 to 2012 were included. Patient ACS-related antithrombotic medication use, laboratory tests, key comorbidities, health care utilization, and direct medical costs were examined. Log-linear regression was conducted to explore factors associated with total direct medical costs. RESULTS: The mean age for the 6601 patients included was 69.7 ± 12.5 years, and most of the patients (73%) were men. Comorbidities included diabetes (18.2%), hypertension (21.2%), and hyperlipidemia (8.6%). Out of these, 6466 (98%) patients had been hospitalized for ACS with an average length of stay of 14.0 ± 16.4 days per hospitalization. A total of 914 (13.8%) patients had emergency room visits. Of these, 93.5% received any antithrombotic therapy, including antiplatelet agents (92.7%) and anticoagulants (20.8%). ACS-related direct medical costs (in yuan renminbi [¥]) were ¥18,421 ± ¥24,741 per hospitalization, including costs for medications (¥6,776) and laboratory tests (¥1,355), and ¥2,894 ± ¥7,060 per outpatient visit, including costs for medications (¥620) and laboratory tests (¥464). The higher direct medical cost was associated significantly (P < 0.05) with age, being male, antiplatelet and anticoagulant use, and several comorbid disease states (diabetes, hyperlipidemia, hypertension, and chronic kidney disease). CONCLUSIONS: Antithrombotic therapeutic treatments were commonly used among patients with ACS in Shanghai, China. Higher treatment costs for patients with ACS in Shanghai, China, involved their antithrombotic medication use and key comorbidities.

Current Practices in Global/International Advanced Pharmacy Practice Experiences: Preceptor and Student Considerations.

The objective of this article is to describe the key areas of consideration for global/international advanced pharmacy practice experience (G/I APPE) preceptors, students and learning objectives. At the 2013 Annual Meeting of the American Association of Colleges of Pharmacy (AACP), the GPE SIG prepared and presented an initial report on the G/IAPPE initiatives. Round table discussions were conducted at the 2014 AACP Annual Meeting to document GPE SIG member input on key areas in the report. Literature search of PubMed, Google Scholar and EMBASE with keywords was conducted to expand this report. In this paper, considerations related to preceptors and students and learning outcomes are described. Preceptors for G/I APPEs may vary based on the learning outcomes of the experience. Student learning outcomes for G/I APPEs may vary based on the type of experiential site. Recommendations and future directions for development of G/IAPPEs are presented. Development of a successful G/I APPE requires significant planning and consideration of appropriate qualifications for preceptors and students.

Twenty years of triptans in the United States Medicaid programs: Utilization and reimbursement trends from 1993 to 2013.

OBJECTIVE: After sumatriptan was approved by the Food and Drug Administration in 1992, triptans became first-line anti-migraine therapies. Rapidly rising triptan expenditures, however, led payers, including Medicaid, to implement cost-containment policies. We describe triptan utilization and reimbursement trends in Medicaid. METHODS: Using national summary files for outpatient drug utilization, utilization and expenditure data from 1993 to 2013 were extracted and summed for all triptan national drug codes reimbursed by Medicaid. Data were collected separately for tablets, injections and sprays. RESULTS: The number of triptan prescriptions increased from 87,348 in 1993 to 0.9 million in 2004; fell to 0.4 million in 2009; rose to 1 million in 2011; and rose 1.2 million in 2013. In 2013, Medicaid spent $96.8 million on triptans: 74.4%, 18.4% and 7.2% for tablets, injections and sprays, respectively. Average reimbursement per prescription was $54 for tablets, $351 for injections and $235 for sprays in 2013. From 1993 to 2013, sumatriptan was the most widely prescribed among the triptans. CONCLUSIONS: The substantial increase in triptan prescriptions from 2009 to 2011, without being convincingly explained by either rising migraine prevalence or rising Medicaid enrollment, is suggestive of reduced access to these medications prior to 2009. Cost-containment policies may have inadvertently prevented Medicaid migraineurs from obtaining appropriate pharmacotherapy. PRIOR PRESENTATIONS: An earlier version of this paper was presented as a poster at the Annual Meeting of the International Society for Pharmacoeconomics and Outcomes Research, Philadelphia, PA, May 2015, where it received a finalist award.

Roles of the pharmacist in the use of safe and highly effective long-acting reversible contraception: an opinion of the women's health practice and research network of the American College of Clinical Pharmacy.

The U.S. population continues to experience an alarmingly high rate of unintended pregnancies that have an impact on individual families and society alike. Lack of effective contraception accounts for most unintended pregnancies, along with incorrect use of contraceptives. The most common reversible contraceptive method used in the United States is the oral contraceptive pill, which has significant failure and discontinuation rates. Use of long-acting reversible contraceptive (LARC) methods has been increasing in recent years after efforts to educate providers and patients. Women are more likely to use LARC methods when barriers such as access and cost are removed. An uptake in the use of LARC methods would allow for markedly reduced contraception failure rates and higher user satisfaction and thus higher continuation rates than those seen with current contraception use. Promoting the use of LARC methods is an important strategy in improving both individual and public health outcomes by reducing unintended pregnancies. The pharmacist's role in family planning is expanding and can contribute to these efforts. Although knowledge regarding LARC has not been studied among pharmacists, a knowledge deficit exists among health care professionals in general. Thus pharmacist education and training should include LARC methods along with other contraceptives. The American College of Clinical Pharmacy Women's Health Practice and Research Network advocates for the pharmacist's role in the use of safe and highly effective LARC methods. These roles include educating patients, informing providers, facilitating access by providing referrals, and modifying institutional procedures to encourage provision of LARC methods.

Safety of long-acting beta agonists and inhaled corticosteroids in children and adolescents with asthma.

The introduction of long-acting beta agonists (LABAs) was considered a major advance in bronchodilator therapy for adult, as well as pediatric, patients with asthma. However, the use of LABAs has raised safety concerns, especially the potential for severe asthma exacerbations (SAEs) resulting in hospitalizations or even death. Meanwhile, the use of inhaled corticosteroids (ICSs), a cornerstone in the treatment of mild-to-severe persistent asthma, has been associated with growth suppression in children. The purpose of this review was to identify and discuss the major published safety studies surrounding LABA, ICS, and combined LABA/ICS usage in children. By way of a critical search for influential published clinical trials, meta-analyses, and observational studies, six studies relevant to the safety of LABA monotherapy, seven studies relevant to ICS monotherapy, and four studies on the subject of LABA/ICS combination usage were identified and reviewed. Based on the reviewed literature, the controversy surrounding these anti-asthma medications was clearly exposed. On the one hand, there is some evidence that LABA monotherapy may be associated with SAEs and asthma-related death, while ICS monotherapy may be associated with a higher risk of growth suppression. On the other hand, the concurrent use of a LABA with an ICS has been associated with positive outcomes including symptom reduction and reduced rate and severity of exacerbations. Further clinical research is warranted and has been called for by the US Food and Drug Administration.

National burden of pediatric hospitalizations for inflammatory bowel disease: results from the 2006 Kids' Inpatient Database.

OBJECTIVES: : The objective of the present study was to quantify the national pediatric inpatient inflammatory bowel disease (IBD) burden in terms of the number of IBD-related hospitalizations, the number of days spent in the hospital, and hospitalization costs. METHODS: : Hospitalizations for children and adolescents 20 years and younger with a primary diagnosis of either Crohn disease (CD) or ulcerative colitis (UC) were selected from the 2006 Kids' Inpatient Database (KID). Length of the hospital stay in days (LOS) and charges for the hospitalization were found directly in the Kids' Inpatient Database, and cost was calculated using the hospital's cost-to-charge ratio. Predictor variables included patient characteristics, such as age and severity of illness, and hospital characteristics. Ordinary-least-squares regressions were developed and estimated to explain hospitalization costs. RESULTS: : In 2006, there were 10,777 IBD-related hospitalizations. The total and mean costs for CD were $66.3 million and $10,176 (95% confidence interval [CI] $9647-$10,705), and for UC were $48.6 million and $11,836 (95% CI $10,760-$12,912). For CD, 0- to 5-year-old patients had the highest mean LOS (8.10, 95% CI 5.53-10.67, days) and mean cost ($13,894, 95% CI $9053-$18,735), whereas, for UC, 11- to 15-year-old patients had the highest mean LOS (7.49, 95% CI 6.88-8.10, 95% CI 5.53-10.67, days) and mean cost ($13,407, 95% CI $11,704-$15,110). CONCLUSIONS: : For a pediatric disease with a rather low prevalence rate, the estimated annual inpatient pediatric burden of IBD is a sizeable $152.4 million (2010 US$) and 64,985 days spent in the hospital. As medications and outpatient treatments improve for the treatment of IBD, there is an opportunity for significant reduction in inpatient burden.

Risk of serious asthma exacerbations associated with long-acting beta agonists among patients with asthma: a retrospective cohort study.

BACKGROUND: After the Serevent Nationwide Surveillance clinical trial, controversy has surrounded the safety of long-acting beta agonists (LABAs). OBJECTIVE: Examine the association between LABAs and severe asthma exacerbations (SAEs). METHODS: From a multistate Medicaid database, for the years 2002-2007, a total of 940,449 patients (age <40) with asthma were selected and divided into a cohort with newly-diagnosed asthma and one with pre-existing asthma. SAEs included asthma-related emergency department (ED) visits, hospitalizations, and intubations. Patients' asthma severity was determined based on medication regimen as suggested by the 2002 National Asthma Guidelines. Specific use of inhaled corticosteroids (ICSs), LABAs, ICS/LABA combination drugs, short-acting beta agonists (SABAs), and other drugs was tracked. Cox proportional hazard regressions were estimated to assess the risk of SAEs associated with patient severity, drug use, and covariates. RESULTS: Compared to patients taking a SABA only, estimated SAE hazard ratios for newly diagnosed and pre-existing-asthma patients were as follows: 0.63 (95% CI 0.58-0.69) and 0.74 (0.70-0.79) for patients on a LABA without ICS, and 0.79 (0.77-0.81) and 0.90 (0.87-0.92) for those on a LABA/ICS single inhaler. Although hazard ratios were estimated to be similar for ED visits, LABA use was found to be positively associated with hospitalizations and intubations. Other key risk factors (P < .0001) included being African American, an alcohol/substance use disorder, pregnancy, and obesity. CONCLUSION: Relative to SABA-only therapy, LABA use is associated with a lower risk of ED visit. Certain patients with asthma, such as pregnant women and African Americans, are particularly vulnerable to SAE risk of all types.
