Initiation of Triple Therapy with Multiple Inhalers in Chronic Obstructive Pulmonary Disease: An Analysis of Treatment Patterns from a U.S. Retrospective Database Study.

BACKGROUND: Evidence suggests that real-world treatment patterns of chronic obstructive pulmonary disease (COPD) do not always follow evidence-based treatment recommendations such as those of the Global Initiative for Chronic Obstructive Lung Disease, which recommends treatment escalation based on disease progression. This U.S. database study evaluated treatment patterns in patients with COPD, focusing on time to initiation of triple therapy using multiple inhalers. OBJECTIVES: To (a) estimate time from diagnosis to initiation of long-acting muscarinic antagonist (LAMA) monotherapy, inhaled corticosteroid (ICS)/long-acting beta2-agonist (LABA) dual therapy, or LAMA/LABA dual therapy; (b) estimate time to initiation of triple therapy from LAMA monotherapy and ICS/LABA or LAMA/LABA dual therapies; and (c) estimate the likelihood of patient progression to triple therapy. METHODS: This study was a retrospective analysis of patients with COPD newly started on LAMA monotherapy, ICS/LABA, or LAMA/LABA therapy between July 1, 2010, and March 31, 2013, as identified in Humana's research database. Patients who were fully insured with commercial or Medicare Advantage insurance plans and were aged ≥ 40 years at index with at least 1 hospitalization, 1 emergency department, or 1 medical office visit claim with a COPD diagnosis in the pre-index year were included in the analysis. Time from diagnosis to initiation of index therapy and time to triple therapy after index therapy were assessed. Multivariable logistic regression models were used to estimate the likelihood of progression to triple therapy. RESULTS: Of 13,541 patients with a confirmed diagnosis of COPD, 4,000 received LAMA monotherapy; 8,207 received ICS/LABA therapy; and 77 received LAMA/LABA therapy at index; mean time (± SD) from COPD diagnosis to initiation of triple therapy was 178 (± 134) days, 185 (± 130) days, and 252 (± 124) days, respectively. During the study, 28% (n = 1,130) of patients receiving LAMA monotherapy and 20% (n = 1,647) of patients receiving dual therapy (ICS/LABA, n = 1,615; LAMA/LABA, n = 32) progressed to triple therapy. Of the patients who progressed to triple therapy, 63% and 57% of patients receiving monotherapy and dual therapy, respectively, progressed in the 12 months after the index date. In the 12 months before initiation of triple therapy, approximately 50% of patients in the LAMA monotherapy, ICS/LABA, and LAMA/LABA therapy groups had an exacerbation. In the multivariable analysis, discontinuation of therapy, smoking history, and concomitant use of xanthenes and short-acting beta2-agonists were significant predictors of progression from index therapy to triple therapy. CONCLUSIONS: Approximately 25% of patients with COPD progressed to triple therapy within 12 months of initiating treatment with monotherapy or dual therapy. Exacerbations were reported in only 50% of these patients, indicating that the other 50% may have escalated to triple therapy for other reasons. Treatment discontinuation, smoking history, the use of a LAMA, and concomitant medication use were significant predictors of progression to triple therapy.

Patterns of Care in Patients with Metastatic Renal Cell Carcinoma Among a U.S. Payer Population with Commercial or Medicare Advantage Membership.

BACKGROUND: Several systemic therapies are now approved for first- and second-line treatment of metastatic renal cell carcinoma (mRCC). Although the National Comprehensive Cancer Network (NCCN) guidelines offer physicians evidence-based recommendations for therapy, there are few real-world studies to help inform the utilization of these agents in clinical practice. OBJECTIVES: To (a) describe the patterns of use associated with systemic therapies for mRCC among Humana members in the United States diagnosed with mRCC, (b) assess consistency with the NCCN guidelines for treatment, and (c) to describe the initial first-line therapy regimen by prescriber specialty and site of care. METHODS: This was a retrospective study using Humana's claims database of commercially insured patients and patients insured by the Medicare Advantage Prescription Drug plan. The study period was from January 1, 2007, to December 31, 2013. Patients with mRCC were identified by ICD-9-CM codes 189.0/189.1 and 196.xx to 199.xx; all patients were between 18 and 89 years of age, had received systemic therapy for their disease, and were followed up for 180 days. Outcome measures included choice of initial systemic therapy, starting and ending doses, first-line treatment persistence and compliance, and choice of second-line therapy. Persistence was measured using time to discontinuation of first-line therapy and proportion of days covered (PDC; the ratio of [total days of drug available minus days of supply of last prescription] to [last prescription date minus first prescription date]). Compliance was measured using the medication possession ratio (MPR; the ratio of [total days supply minus days supply of last prescription] to [last prescription date minus first prescription date]). RESULTS: A total of 649 patients met all inclusion criteria; 109 were insured by commercial plans and 540 were insured by Medicare. The mean ± SD age of patients was 68.6 ± 9.4 years, and 68.6% were male; Medicare patients were older than commercial patients (71.7 ± 7.4 vs. 56.6 ± 9.1 years, respectively; P < 0.001). The most common comorbidities among the patient population were hypertension, hyperlipidemia, diabetes, and heart disease. The majority of patients (68.6%) received an oral tyrosine kinase inhibitor (TKI) as their first line of therapy: 43.9% received sunitinib, 14.0% received sorafenib, 10.0% received pazopanib, and 0.6% received axitinib. Mean ± SD time to discontinuation of first-line TKI treatment was 169.1 ± 29.5 days with sunitinib, 160.3 ± 41.1 days with pazopanib, and 160.1 ± 41.4 days with sorafenib. Other first-line therapies included inhibitors of mammalian target of rapamycin (mTOR) (19.7%) and the antivascular endothelial growth factor agent bevacizumab (9.4%). Among patients receiving mTOR inhibitors, 14.8% were started on temsirolimus and 4.9% were started on everolimus. The median starting and ending doses were the same for each drug except for sunitinib. Mean ± SD times to discontinuation of temsirolimus, everolimus, and bevacizumab were 171.8 ± 26.2, 137.0 ± 62.2, and 150.8 ± 56.0 days, respectively. Persistence on first-line regimen as measured by PDC was high (PDC ≥ 80%) for 89% of oral therapies and 77% of injectable therapies; first-line compliance was high (MPR ≥ 80%) for 77% of oral therapies and 68% of injectables. Among patients who received second-line therapy, the most common regimen was everolimus (29.2%), followed by bevacizumab (19.8%), temsirolimus (15.6%), and sunitinib (13.6%). Specialty codes obtained from the database provider identified internal medicine specialists and oncologists as the most common prescribers of TKIs and mTOR inhibitors. CONCLUSIONS: Patterns of use were similar for each of the prescribed systemic treatments for mRCC, and the majority of patients were highly persistent and compliant with first-line therapies. Time to treatment discontinuation was slightly longer with oral agents compared with injectable drugs.

Pharmacy students' ability to identify plagiarism after an educational intervention.

Objective. To determine if an educational intervention in a doctor of pharmacy (PharmD) degree program increases pharmacy students' ability to identify plagiarism. Methods. First-year (P1), second-year (P2), and third-year (P3) pharmacy students attended an education session during which types of plagiarism and methods for avoiding plagiarism were reviewed. Students completed a preintervention assessment immediately prior to the session and a postintervention assessment the following semester to measure their ability. Results. Two hundred fifty-two students completed both preintervention and postintervention assessments. There was a 4% increase from preintervention to postintervention in assessment scores for the overall student sample (p<0.05). The mean change was greatest for P1 and P2 students (5% and 4.8%, respectively). Conclusion. An educational intervention about plagiarism can significantly improve students' ability to identify plagiarism.

Exploring patient experiences with prescription medicines to identify unmet patient needs: implications for research and practice.

BACKGROUND: Pharmacy services are offered to patients, and often, they decline participation. Research is needed to better understand patients' unmet needs when taking prescribed medications. OBJECTIVE: To identify and characterize patients' unmet needs related to using prescribed medication for chronic conditions. METHODS: Focus groups of patients using prescription medication for chronic conditions discussed their experiences with medications, starting from initial diagnosis to ongoing management. Sessions involved 40 patients from 1 Midwestern U.S. state. Major themes were identified using content analysis. RESULTS: Three major themes emerged. First, patients seek information to understand their health condition and treatment rationale. Patients form an illness perception (its consequence, controllability, cause, and duration) that dictates their actions. Second, patients desire to be involved in treatment decisions, and they often feel that decisions are made for them without their understanding of the risk-to-benefit trade-off. Third, patients monitor the impact of treatment decisions to determine if anticipated outcomes are achieved. CONCLUSION: The results were consistent with Dowell's therapeutic alliance model (TAM) and Leventhal's common sense model (CSM). The TAM can be used to model the consultative services between pharmacists and patients. The impact of the new services (or interventions) can be evaluated using the CSM. Patients expressed a strong desire to be involved in their treatment decisions. The effectiveness of medication therapy management services may be enhanced if pharmacists build on patients' desire to be involved in their treatment decisions and assist them to understand the role of medications and their risks and expected outcomes within the context of the patients' perceptions of illness and desired coping strategies.

Ethnic variation in symptoms and response to risperidone in youths with schizophrenia-spectrum disorders.

BACKGROUND: Evaluation of symptom presentation and antipsychotic response based on ethnicity in children and adolescents with schizophrenia is limited. The purpose of this naturalistic, retrospective database study was to compare symptom presentation of children and adolescents of different ethnicities with schizophrenia-spectrum disorders, and response to risperidone. METHOD: African-American (n = 38), Caucasian (n = 30), or Hispanic (n = 37) youths started on risperidone were eligible. Child Behavior Checklist (CBCL) total, internalizing, and externalizing scores were evaluated at baseline, 90 days, 1 year, and 2 year intervals. RESULTS: At baseline, Hispanic patients had lower CBCL externalizing scores than African-Americans or Caucasians. African-Americans showed significant differences in CBCL total, internalizing, and externalizing scores at 90 days compared to baseline. Hispanics showed improvement in CBCL internalizing scores over the 2 year period. No significant improvements were observed in Caucasians. African-American patients had significantly lower CBCL total at 90 days compared to Hispanic patients. No significant difference existed in 2 year hospitalization rates between groups. CONCLUSIONS: These findings suggest that ethnicity may play a role in symptom presentation and treatment response to risperidone for children and adolescents with schizophrenia-spectrum disorders. Future studies in children and adolescents are necessary to examine ethnospecific differences in antipsychotic use and treatment response.
