Provider and clinical setting characteristics associated with tobacco pharmacotherapy dispensed in the Veterans Health Administration.

INTRODUCTION: While initiation rates of tobacco cessation pharmacotherapy have improved both inside and outside the Department of Veteran Affairs (VA), prescribing rates remain low. The objective of this study was to examine correlation of the characteristics of providers, clinics, and facilities with initiation of tobacco cessation pharmacotherapy. METHODS: This retrospective, observational study used VA outpatient electronic medical record data from federal fiscal year 2011. Logistic regression models estimated the adjusted odds ratio associated with provider characteristics for pharmacotherapy initiation. RESULTS: For the 639507 veterans who used tobacco, there were 30388 providers caring for them. Younger (p<0.001) and female (p<0.001) providers were more likely to initiate tobacco cessation pharmacotherapy. Compared to physicians, pharmacists were 74% more likely to initiate pharmacotherapy, while all groups of nurses were 5-8% and physicians' assistants were 12% less likely (p<0.001). Compared to those seen in primary care clinics, patients assessed in substance use treatment clinics were 16% more likely to have pharmacotherapy initiated (p<0.001), while those in psychiatry were 10% less likely (p<0.001), and those in outpatient surgery were 39% less likely to initiate pharmacotherapy (p<0.001). Compared to almost all other classes of VA facilities, patients seen in primary care community-based outpatient clinics (CBOCs) were 7-28% more likely to initiate pharmacotherapy (p<0.0001). CONCLUSIONS: While the VA is at the leading edge of providing tobacco cessation pharmacotherapy, targeting quality improvement efforts towards providers, clinics, and facilities with low prescribing rates will be essential to continue the declining rates of tobacco use among VA patients.

Use of targeted therapies for advanced renal cell carcinoma in the Veterans Health Administration.

BACKGROUND: The objective of this study is to describe the use of targeted therapies for the treatment of advanced renal cell carcinoma (RCC) and overall survival (OS) among patients in clinical practice in the Veterans Health Administration (VHA). METHODS: A retrospective cohort of 286 patients from 24 VHA Medical Centers diagnosed with advanced clear cell RCC between Fiscal Year (FY) 2010 and FY2014 was followed through September 30, 2016. Among patients who received targeted therapy, we described the medications taken, duration of therapy, and overall survival. We also assessed the effect of the first therapy received on overall survival using Cox Proportional Hazards models. RESULTS: There were 66 patients who did not receive therapy for their advanced RCC. Of the 220 treated patients, the mean (sd) number of medications received was 1.9 (1.1). The medications most commonly used first were sunitinib (61.8%), pazopanib (17.3%), and temsirolimus (10.9%). The median duration of first-line therapy was 86 days (interquartile range [IQR] 42, 210). Median total duration of therapy was 159 days (IQR 58, 397). 62.3% of patients had ≥ 1 dose of therapy held or reduced, mainly due to an adverse drug event (ADE). Median survival from the start of treatment to death was 1.08 years (IQR 0.80, 1.31). Finally, receipt of temsirolimus vs sunitinib (HR 1.95 [95%CI 1.09,3.47]) as the first targeted therapy was independently associated with an increased hazard of death. CONCLUSION: Our analysis of targeted therapies for advanced RCC in VHA suggests duration of treatment is shorter in a real-world setting than in clinical trials, and dose reductions and ADEs are more common.

Cost-effectiveness of real-world administration of tobacco pharmacotherapy in the United States Veterans Health Administration.

BACKGROUND AND AIMS: Cost-effectiveness studies in randomized clinical trials have shown that tobacco cessation pharmacotherapy is among the most cost-effective of health-care interventions. Clinical trial eligibility criteria and treatment protocols may not be followed in actual practice. This study aimed to determine whether tobacco cessation pharmacotherapy is cost-effective in real-world settings. DESIGN: A retrospective analysis of costs and outcomes. SETTING: Hospitals and clinics of the US Veterans Health Administration, USA. PARTICIPANTS: A total of 589 862 US veterans who screened positive for tobacco use in 2011. INTERVENTION AND COMPARATOR: Tobacco users who initiated smoking cessation pharmacotherapy in the 6 months after screening were compared with those who did not use pharmacotherapy in this period. Pharmacotherapy included nicotine replacement therapy, bupropion (if prescribed at 300 mg per day or specifically for tobacco cessation) or varenicline. MEASURES: Effectiveness was determined from responses to a subsequent tobacco screening conducted between 7 and 18 months after the treatment observation period. Cost of medications and prescribing health-care encounters was determined for the period between initial and follow-up tobacco use screening. Multivariate fixed-effects regression was used to assess the effect of initial treatment status on cost and outcome while controlling for differences in case-mix with propensity weighting to adjust for confounding by indication. FINDINGS: Thirteen per cent of participants received tobacco cessation pharmacotherapy within 6 months of initial screening. After an average of an additional 218.1 days' follow-up, those who initially received pharmacotherapy incurred $143.79 in additional treatment cost and had a 3.1% absolute increase in tobacco quit rates compared with those who were not initially treated. This represents an incremental cost-effectiveness ratio of $4705 per quit. The upper limit of the 99.9% confidence region was $5600 per quit. Without propensity adjustment, the cost-effectiveness ratio was $7144 per quit, with the upper limit of the 99.9% confidence region $9500/quit. CONCLUSIONS: Tobacco cessation pharmacotherapy provided by the US Veterans Health Administration in 2011/12 was cost-effective in this real-world setting, with an incremental cost-effectiveness ratio of $4705 per quit.

Effectiveness of tobacco cessation pharmacotherapy in the Veterans Health Administration.

INTRODUCTION: In 2003, the Veterans Health Administration (VHA) implemented a directive that cessation pharmacotherapy be made available to all who use tobacco and are interested in quitting. Despite the efficacy of cessation pharmacotherapy shown in clinical trials, the generalisability of the results in real-world settings has been challenged. Hence, the specific aim of this study was to determine the effectiveness of cessation pharmacotherapies in the VHA. METHODS: This retrospective cohort study used VHA's electronic medical record data to compare quit rates among those who use tobacco and who did vs. did not receive any type of cessation pharmacotherapy. Included were 589 862 Veterans identified as current tobacco users during fiscal year 2011 who had not received cessation pharmacotherapy in the prior 12 months. Following a 6-month period to assess treatment, quit rates among those who were treated versus untreated were compared during the 7-18 months (12 months) post-treatment follow-up period. The estimated treatment effect was calculated from a logistic regression model adjusting for inverse probability of treatment weights (IPTWs) and covariates. Marginal probabilities of quitting were also obtained among those treated versus untreated. RESULTS: Adjusting for IPTWs and covariates, the odds of quitting were 24% higher among those treated versus untreated (OR=1.24, 95% CI 1.23 to 1.25, p<0.001). The marginal probabilities of quitting were 16.7% for the untreated versus 19.8% for the treated based on the weighted model. CONCLUSION: The increased quit rates among Veterans treated support the effectiveness and continuation of the VHA tobacco cessation pharmacotherapy policy.

Trends and Patient Characteristics Associated with Tobacco Pharmacotherapy Dispensed in the Veterans Health Administration.

Introduction: There is evidence suggesting that certain subgroups of people who use tobacco do not receive tobacco pharmacology as consistently as others. Methods: This retrospective, cohort study examined the trend in the use of cessation pharmacotherapy from 2004 to 2013 using Veterans Health Administration (VHA) administrative data. Among Veterans who used tobacco in the fiscal year (FY) 2011 and had not received pharmacotherapy in the prior year, multivariable Cox regression was used to assess the independent associations between patient clinical and demographic characteristics and pharmacotherapy initiation in the 6-months follow-up period. Results: Smoking cessation pharmacotherapy in the VHA increased from 13.8% in 2004 to 25.6% in 2013. In 2011, Veterans (N = 838309) who were more likely to newly receive pharmacotherapy included those with psychiatric disorders (depression, bipolar disorder, non-alcohol substance use disorder, other anxiety, and post-traumatic stress disorder), chronic pulmonary disease, peripheral vascular disorders, and younger Veterans (adjusted rate ratios (ARRs) ranged from 1.03 to 1.92, all p < .001). Veterans less likely to receive pharmacotherapy were those with schizophrenia or other psychosis, males, Hispanics, and those with a medical condition (uncomplicated diabetes, uncomplicated hypertension, fluid and electrolyte disorders, cardiac arrhythmia, valvular disease, hypothyroidism, acquired immunodeficiency syndrome/human immunodeficiency virus, deficiency anemia, renal failure, paralysis, coagulopathy, metastatic cancer, and other neurological disorders) (ARRs ranged from 0.74 to 0.93, all p < .001). Conclusions: Although VHA cessation pharmacotherapy use nearly doubled from 13.8% in 2004 to 25.6% in 2013, reaching undertreated subgroups, especially those with medical comorbidities, may improve cessation outcomes. Implications: Despite evidence that demographics influence the use of pharmacotherapy in smoking cessation, there is limited and contradictory information regarding how psychiatric and chronic medical illnesses affect pharmacotherapy use. Administrative data were used to determine trends and patient characteristics of those receiving pharmacotherapy to aid in smoking cessation in the Veterans Health Administration. From 2004 to 2013, pharmacotherapy use increased from 13.8% to 25.6% of current smokers. Factors associated with increased pharmacotherapy initiation were psychiatric disorders, chronic pulmonary disease, peripheral vascular disorders, and younger age. Veterans with schizophrenia or other psychosis, males, Hispanics, and most medical conditions were less likely to receive pharmacotherapy.

National trends in the provision of smoking cessation aids within the Veterans Health Administration.

OBJECTIVES: To evaluate the effectiveness of the Veterans Health Administration (VHA) in providing treatment for tobacco dependence, accomplished by estimating national trends in the number and percent of smokers receiving smoking cessation aids (SCAs) within the VHA, trends in SCA utilization and expenditures, and the impact of lifting restrictions on patient access to SCAs. STUDY DESIGN AND METHODS: All patients receiving an outpatient SCA prescription were identified within the Veterans Affairs (VA) Pharmacy Benefits Management database over a 4-year period- October 1, 1998 (n = 61 968) to September 30, 2002 (n = 76 641). Smoking prevalence was based on data from the VA's 1999 Large Health Survey of Enrollees. A subsample of sites was classified as having restricted access to SCAs if patients were required to attend smoking cessation classes. Changes in annual SCA utilization rates and expenditures by SCA type and restriction status were measured to assess changes in treatment of tobacco dependence. RESULTS: Approximately 7% of smokers received SCA prescriptions, and SCAs accounted for less than 1% of the VHA's annual outpatient pharmacy budget in any given year. Following downward trends in the cost of 30-day SCA prescriptions, annual SCA expenditures per patient decreased over time. Expenditures were lower for restricted than unrestricted sites. More than two thirds of smokers who were prescribed medications received the nicotine patch, a quarter received bupropion sustained-release, and fewer than 10% received nicotine gum. CONCLUSIONS: Measures of SCA utilization and cost are low, stable, and less than the recommended rates in national smoking cessation guidelines, suggesting that this population of smokers is undertreated. Removing SCA restrictions is not prohibitively expensive and improves access to cost-effective care.
