Abstract
Purpose Chronic obstructive pulmonary disease (COPD) affects approximately 174 million people worldwide. The objective was to determine the trends of COPD medication use in a group of Colombian patients. Patients and Methods This was a retrospective study on prescription patterns of bronchodilators and other medications used in COPD from a population database with follow-up at 12 and 24 months. Patients older than 18 years of age of any sex with a COPD diagnostic code between 2017 and 2019 were included. Sociodemographic variables, medications, treatment schedules for COPD, comorbidities, comedications, and the specialty of the prescriber were considered. Results Data from 9476 people with COPD was evaluated. The mean age was 75.9 ± 10.7 years, 50.1% were male, and 86.8% were prescribed by a general practitioner. A total of 57.9% had comorbidities, most often hypertension (44.4%). At the baseline measurement, on average, they received 1.6 medications/patient, mainly short-acting antimuscarinics (3784; 39.9%), followed by short-acting β-agonists (2997, 31.6%) and inhaled corticosteroids (ICS) (2239, 23.6%); more than half (5083, 53.6%) received a long-acting bronchodilator. Prescription of triple therapy (antimuscarinic, β-agonist, and ICS) went from 645 (6.8%) at baseline to 1388 (20.6%) at the 12-month mark. Conclusion This group of patients with COPD treated in Colombia frequently received short-acting bronchodilators and ICS, but a growing proportion are undergoing controlled therapy with long-acting bronchodilators, a situation that can improve the indicators of morbidity, exacerbations, and hospitalization.

Real-World Healthcare Resource Utilization and Cost Burden Assessment for Adults With Generalized Myasthenia Gravis in the United States. Front Neurol 2022; 12:809999. [PMID: 35115997 PMCID: PMC8805609 DOI: 10.3389/fneur.2021.809999] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2021] [Accepted: 12/21/2021] [Indexed: 11/30/2022] Open
Abstract
Introduction Limited evidence exists for healthcare resource utilization (HCRU) and costs associated with generalized myasthenia gravis (gMG), a rare autoimmune disorder, for adults in the United States. Methods Adults with ≥1 diagnostic claim for MG between 2014 and 2019 were identified using Symphony Health's Integrated Dataverse®. Using a novel algorithm, HCRU and costs over 12 months following index dates were evaluated for patients with gMG including those with exacerbation events. For patients who experienced crisis events, HCRU and costs were analyzed during the 36 months preceding, during, and 12 months following the events. Results Mean HCRU and costs were higher for newly diagnosed patients compared with previously diagnosed patients (hospitalizations: 0.46 vs. 0.34; all-cause costs: $26,419.20 vs. $24,941.47; direct costs for gMG treatments: $9,890.37 vs. $9,186.47) and further increased for patients with exacerbation events (hospitalizations: 0.72; all-cause costs: $43,734.15; direct costs for gMG treatments: $21,550.02). For patients who experienced crisis events, HCRU and costs markedly increased during the 12 months immediately before the crisis event (hospitalizations: 1.35; all-cause costs: $49,236.68) compared with the 2 preceding years and increased further during the 12 months following the crisis index date (hospitalizations: 2.78; all-cause costs: $173,956.99). Cost increases were, in large part, attributed to treatments received. Discussion New diagnosis, exacerbation, and crisis events were drivers of HCRU and cost for patients with gMG. Particularly, high costs of gMG-specific medications associated with intervention for exacerbation and crisis events contributed to increased all-cause costs.

Real-World Persistence, Maintenance Dosing, and Pre-Post Corticosteroid and Opioid Use Among Crohn's Disease Patients with Prescription Claims for Ustekinumab in the USA. Drugs Real World Outcomes 2021; 8:565-575. [PMID: 34136998 PMCID: PMC8605940 DOI: 10.1007/s40801-021-00264-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 05/18/2021] [Indexed: 12/22/2022] Open
Abstract
Background Real-world evidence for how US Crohn’s disease (CD) patients use ustekinumab is limited. Objectives The aim of this study was to describe the persistence, maintenance dosing, and pre-post corticosteroid and opioid use for CD patients in the USA treated with ustekinumab and those treated with adalimumab as a commonly used descriptive reference product. Methods CD patients aged ≥ 18 years with ≥2 CD diagnoses between 1 October 2012 and 31 May 2018 and ≥ 1 new (i.e., no claim for at least 1 year) outpatient pharmacy claim for ustekinumab or adalimumab (first claim date = index date) on or after 26 September 2016 were selected from Symphony Health database. McNemar’s tests were used to derive the p-values for pre-post changes in corticosteroid and opioid use within each treatment cohort. Results A total of 1073 ustekinumab and 2904 adalimumab patients met analysis criteria. Using a 90-day rule for discontinuation, persistence at 1 year post-index was 69.8% for ustekinumab and 65.1% for adalimumab. The majority received doses within ±30% of the approved labeling (ustekinumab 81.1%; adalimumab 78.8%). Doses higher than US package insert (PI) recommended maintenance dose were 7.0% for ustekinumab and 13.6% for adalimumab for 30% above PI, respectively; and 4.0% versus 9.4% for 50% above PI, respectively. Rates of pre-index biologic use suggest that patients treated with ustekinumab may have greater CD severity based on a greater percentage being biologic-experienced (ustekinumab 51.5% and adalimumab 8.4%). From pre- to post-index, the relative proportion of ustekinumab patients with ≥ 1 pharmacy claim for corticosteroids decreased by 25.5% (p < 0.0001) and opioids decreased by 8.4% (p = 0.0030). Results for adalimumab (a commonly used descriptive reference product in CD) showed generally similar trends. Conclusions In this real-world study, persistence for ustekinumab remained high at 1 year. The majority of the patients in the ustekinumab cohort followed US PI recommended dosing. The percentage of patients with average dose above PI recommendations over 1 year were low for ustekinumab. Reductions in the proportion of patients with claims for corticosteroids or opioids were observed in patients using ustekinumab.

Abstract
AIMS This study compared medication use, healthcare resource utilization (HRU), and exacerbations among individuals with chronic obstructive pulmonary disease (COPD) who initiated glycopyrrolate/eFlow Closed System nebulizer 25 mcg/mL glycopyrrolate (hereafter GLY) in a real-world setting before and after treatment initiation. MATERIALS AND METHODS Retrospective claims and hospital charge master data were used to identify individuals ≥ 40 years of age diagnosed with COPD who initiated GLY between 1 April 2018 and 28 February 2019 (first prescription claim = index date). Patients were excluded if they had ≥1 asthma diagnosis in the 6-month pre-index period. The proportion of patients with COPD-related medications, other outpatient HRU, hospitalizations, and exacerbations were compared between the 6-month pre-index and 6-month follow-up periods. Among patients utilizing the service, per-person utilization rates were compared between the two periods. RESULTS Among patients initiating GLY (n = 767), the mean age was 71.4 years, 56.1% were female, and the mean Charlson Comorbidity Index score was 2.0. The mean number of GLY claims per person was 3.8 during the follow-up period. Compared to the pre-index period, a lower proportion of patients had claims for COPD medications including oral corticosteroids (62.1% vs. 69.1%, p = .0001) and fixed-dose SAMA/SABA (26.1% vs. 33.0%, p < .0001) and a higher proportion of patients had claims for LABA (29.7% vs. 22.6%, p < .0001) during the follow-up period. Fewer patients had ≥1 COPD-related physician office visit (42.4% vs. 49.8%, p < .0001), radiology test (40.7% vs. 46.5%, p = .005), or moderate exacerbation (48.0% vs. 53.2%, p = .01) after initiating GLY. Among patients with linkage to inpatient data (n = 316), fewer were hospitalized (7.9% vs. 13.0%, p = .037) and hospital length of stay was shorter (1.9 vs. 3.6 days, p = .017) after initiating GLY/eFlow. CONCLUSIONS Among patients initiating GLY in a real-world setting, COPD medications, hospitalizations, other HRU, and exacerbations decreased after treatment initiation compared with the 6-month pre-index period.

Abstract
The coronavirus pandemic, known as coronavirus disease 2019 (COVID-19), is an infectious respiratory disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a novel coronavirus first identified in patients from Wuhan, China. Since December 2019, SARS-CoV-2 has spread swiftly around the world, infected more than 25 million people, and caused more than 800,000 deaths in 188 countries. Chronic respiratory diseases such as asthma and chronic obstructive pulmonary disease (COPD) appear to be risk factors for COVID-19, however, their prevalence remains controversial. In fact, studies in China reported lower rates of chronic respiratory conditions in patients with COVID-19 than in the general population, while the trend is reversed in the United States and Europe. Although the underlying molecular mechanisms of a possible interaction between COVID-19 and chronic respiratory diseases remain unknown, some observations can help to elucidate them. Indeed, physiological changes, immune response, or medications used against SARS-CoV-2 may have a greater impact on patients with chronic respiratory conditions already debilitated by chronic inflammation, dyspnea, and the use of immunosuppressant drugs like corticosteroids. In this review, we discuss importance and the impact of COVID-19 on asthma and COPD patients, the possible available treatments, and patient management during the pandemic.
