Disease Burden and Treatment Patterns of Psoriasis in Russia: A Real-World Patient and Dermatologist Survey.

INTRODUCTION: Data regarding disease burden and quality of life (QoL) for patients with psoriasis from Russia are limited. The objective of this study was to describe the demographic and clinical characteristics, comorbidities, and treatment patterns of systemic therapy eligible psoriasis patients in Russia in order to assess the impact of psoriasis on the QoL and work productivity of the patients and to evaluate patient/dermatologist concordance on disease severity, signs/symptoms, and satisfaction with psoriasis treatment. METHODS: Data were collected by the Growth from Knowledge Disease Atlas global real-world evidence programme from nine countries. The data from the Russian population are presented here. Adult patients who had a current or prior history of moderate-to-severe psoriasis and were receiving prescription treatment at the time of the survey were included. Dermatologist-reported data on disease severity, symptoms, comorbidities, and treatment as well as patient-reported data on QoL and work productivity were collected. Descriptive analysis of the data was conducted. Patient/dermatologist concordance was assessed using Cohen's κ. RESULTS: A total of 300 patients from Russia were included. The mean Psoriasis Area and Severity Index score was 9.0 and the mean disease duration was 9.9 years. The proportion of patients with itch, skin pain, and comorbidities increased as current psoriasis severity increased. The disease had a negative impact on patients' QoL (mean Dermatology Life Quality Index score: 7.1) and work productivity (33.2% drop in work productivity), which further deteriorated as disease severity increased. A large proportion of the enrolled patients (60%) were treated with topical agents only. Overall, the level of concordance between patients and their dermatologists regarding psoriasis severity and satisfaction with overall disease control achieved was low. CONCLUSION: Results demonstrate a substantial disease burden on psoriasis patients in Russia, despite receiving treatment for their psoriasis, as well as low patient/dermatologist concordance of views on treatment outcomes. These findings also highlight a need to further incorporate the patient's views into treatment decision-making in Russia. FUNDING: Novartis Pharma AG, Basel, Switzerland.

A cost-effectiveness analysis of varenicline for smoking cessation using data from the EAGLES trial.

BACKGROUND: The cost-effectiveness of varenicline has been demonstrated in the US health care setting using the Benefits of Smoking Cessation on Outcomes (BENESCO) model to simulate the lifetime direct costs and consequences of a hypothetical cohort of US adult smokers who make a single attempt to quit. The aim of this study was to undertake an updated cost-effectiveness analysis, using current epidemiology inputs and recently published smoking cessation data from the Evaluating Adverse Events in a Global Smoking Cessation Study (EAGLES), the largest clinical trial of smoking cessation pharmacotherapies conducted to date. METHODS: BENESCO is a Markov model simulating the effect of a single attempt to quit smoking on four smoking-related diseases: coronary heart disease, stroke, chronic obstructive lung disease, and lung cancer. Inputs were updated to include efficacy from EAGLES and newer data for the epidemiology of smoking in the US, the epidemiology and direct treatment costs of the four morbidities, and the costs of the interventions. Analyses compared varenicline, bupropion, nicotine replacement therapy (NRT) patch, and placebo with regard to the incidence of smoking-related morbidity, the incidence of smoking-related mortality, and cost-effectiveness at a time horizon from 2 years to lifetime. RESULTS: The study cohort comprised of 18,394,068 US adult smokers who made a single quit attempt during the first year of the model. For varenicline, there were an estimated 319,730 fewer smoking-related morbidities at the lifetime compared with placebo. Similarly, smoking-related mortality decreased by 198,240 subjects when varenicline was compared with placebo. For the same time horizon, varenicline was more effective and less costly, ie, dominant, compared with all comparators in the cost-effectiveness analysis. CONCLUSION: Based on the BENESCO model, smoking cessation with varenicline results in reduced incidence of smoking-related morbidity and mortality compared with other smoking cessation interventions and remains a cost-effective strategy in the US population.

Budget impact assessment of Aprokam® compared with unlicensed cefuroxime for prophylaxis of post-cataract surgery endophthalmitis.

BACKGROUND: Intracameral cefuroxime is recommended as prophylaxis against postoperative endophthalmitis (POE) following cataract surgery. Aprokam is the only licensed product for prophylaxis of POE, although unlicensed intracameral cefuroxime may be administered using pre-filled syringes (PFS), either prepared in hospital by reconstituting cefuroxime via serial dilution (prepared PFS), or commercially purchased (purchased PFS). This study aimed to estimate the potential budget impact of using Aprokam over unlicensed cefuroxime for intracameral administration. METHODS: A budget impact model (BIM) was developed from UK NHS hospital perspective to estimate the economic impact of adopting Aprokam compared with purchased PFS or prepared PFS for the prophylaxis of POE following cataract surgery over a 5-year time horizon. The BIM incorporated direct costs only, associated with the acquisition, delivery, storage, preparation, and administration of cefuroxime. Resource utilisation costs were also incorporated; resource utilisation was sourced from a panel survey of hospital pharmacists, surgeons, and theatre nurses who are involved in the delivery, storage, preparation, quality assurance, or administration of cefuroxime formulations. Unit costs were sourced from NHS sources; drug acquisition costs were sourced from BNF. The model base case used a hypothetical cohort comprising of 1000 surgeries in the first year and followed a 5.2 % annual increase each year. RESULTS: The model predicts Aprokam is cost saving compared with purchased PFS, with a modest increase compared prepared PFS over 5 years. There are total savings of £ 3490 with Aprokam compared with purchased PFS, driven by savings in staff costs that offset greater drug acquisition costs. Compared with prepared PFS, there are greater drug acquisition costs which drive an increased total cost over 5 years of £ 13,177 with Aprokam, although there are substantial savings in staff costs as well as consumables and equipment costs. CONCLUSIONS: The lower direct costs of using Aprokam compared with purchased PFS presents a strong argument for the adoption of Aprokam where purchased PFS is administered. The additional benefits of Aprokam include increased liability coverage and possible reduction in dilution errors and contaminations; as such, in hospitals where unlicensed prepared PFS is used, modest additional resources should be allocated to adoption of Aprokam.

Association between long-acting reversible contraceptive use, teenage pregnancy, and abortion rates in England.

BACKGROUND: Since the late 1990s, the British government has launched major strategies to address high teenage pregnancy and abortion rates in England. These have focused in part on improving access to contraception through national campaigns. This study assessed teenage pregnancy and abortion rate trends since 1998 and possible associations with usage of long-acting reversible contraceptives (LARCs). METHODS: Teenage conception rates and age-specific abortion rates were obtained from the Office for National Statistics and the Department of Health. LARC usage data was obtained for Depo-Provera, Implanon/Nexplanon, intrauterine devices, Mirena, and Noristerat from the IMS British Pharmaceutical Index, IMS Hospital Pharmacy Audit, IMS Disease Analyzer, and KT-31 reports. Through linear regression methods, changes in conception and abortion-related outcomes during 1998-2011 and the associations with LARC usage were assessed. RESULTS: Conception rates for girls younger than 18 years of age decreased significantly between 1998-2011, from 46.6 to 30.7 per 1,000 girls. A statistically significant association was observed between this decrease and increased LARC usage (P=0.0024) in this population. Abortion rates among females aged <18 years or aged 18-19 years decreased between 1998-2011, and their associations with increased LARC usage were statistically significant (P=0.0029 and P=0.0479, respectively). The pattern in older women was complex; abortion rates in women aged 20-24 years or 25-34 years increased slightly from 1998 to 2011, with stabilization during 2007-2011. CONCLUSION: Increased LARC usage in England was significantly associated with decreased teenage pregnancy rates and abortion rates in females aged <20 years. Government strategies appears to have a positive impact on these outcomes; however, abortion rates among women over 20 years of age remain an issue.

Compliance with pharmacotherapy and direct healthcare costs in patients with Parkinson's disease: a retrospective claims database analysis.

BACKGROUND: Parkinson's disease (PD) is a progressive neurological disorder for which, at present, there is no cure. Current therapy is largely based on the use of dopamine agonists and dopamine replacement therapy, designed to control the signs and symptoms of the disease. The majority of current treatments are administered in tablet form and can involve multiple daily doses, which may contribute to sub-optimal compliance. Previous studies with small groups of patients suggest that non-compliance with treatment can result in poor response to therapy and may ultimately increase direct and indirect healthcare costs. OBJECTIVE: To determine the extent of non-compliance within the general PD population in the USA as well as the patient characteristics and healthcare costs associated with compliance and non-compliance. METHODS: A retrospective analysis from a managed care perspective was conducted using data from the USA PharMetrics patient-centric claims database. PharMetrics claims data were complete from 31 December 2005 to 31 December 2009. Patients were included if they had at least two diagnoses for PD between 31 December 2005 and 31 December 2008, were older than 18 years of age, were continuously enrolled for at least 12 months after the date of the most recent PD diagnosis, and had no missing or invalid data. The follow-up period was the most recent 12-month block of continuous enrollment that occurred between 2006 and 2009. Patients were required to have at least one PD-related prescription within the follow-up period. The medication possession ratio (MPR) was used to categorise patients as compliant or non-compliant. Direct all-cause annual healthcare costs for patients with PD were estimated for each patient, and regression analyses were conducted to determine predictors for non-compliance. RESULTS: A total of 15,846 patients were included, of whom 46 % were considered to be non-compliant with their prescribed medication (MPR <0.8). Predictors of non-compliance included prescription of a medication administered in multiple daily doses (p < 0.0001), a period of <2 years since the initial PD diagnosis (p = 0.0002), a diagnosis of gastrointestinal disorder (p < 0.0001), and a diagnosis of depression (p < 0.0001). Non-compliance was also found to be related to age, with a lower odds of non-compliance in patients aged 41-80 years than in patients aged ≥81 years (p < 0.05). Although total drug mean costs were higher for compliant patients than non-compliant patients (driven mainly by the cost of PD-related medications), the mean costs associated with emergency room and inpatient visits were higher for patients non-compliant with their prescribed medication. Overall, the total all-cause annual healthcare mean cost was lower for compliant ($77,499) than for non-compliant patients ($84,949; p < 0.0001). CONCLUSION: Non-compliance is prevalent within the general USA PD population and is associated with a recent PD diagnosis, certain comorbidities, and multiple daily treatment dosing. Non-compliance may increase the burden on the healthcare system because of greater resource usage compared with the compliant population. Treatments that require fewer daily doses may have the potential to improve compliance, which in turn could reduce the economic burden associated with PD.

Influence of sociodemographic factors on quality of life during pollen season in seasonal allergic rhinitis patients.

BACKGROUND: Quality of life (QOL) is an important outcome in asthma and seasonal allergic rhinitis (SAR), and its determinants are imperfectly understood. More specifically, the influence of sociodemographic factors on QOL in patients with SAR has been so far little investigated. OBJECTIVE: To examine the changes of QOL during the pollen season in patients with isolated SAR or SAR associated with asthma. METHODS: A prospective cohort study was conducted in southern France. Outpatients aged 18 to 60 years and regularly treated by respiratory physicians for SAR (with or without associated asthma) were identified. Patients were recruited before the grass or ragweed pollination period. At peak pollination, patients completed the French versions of the Mini Rhino-conjunctivitis Quality of Life Questionnaire (mini-RQLQ) and the 12-item Short-Form Health Survey (SF-12) physical component summary (PCS) and mental component summary (MCS). RESULTS: A total of 135 patients was included, 83 with isolated SAR and 52 with associated asthma (mean age, 35.4 years; SD, 10.6 years; 56% female). At pollen peak, QOL scores were lower in women for all instruments, with significant effects on SF-12 MCS and PCS scores in multivariate analyses. Likewise, a university-level education was an independent predictor of higher SF-12 PCS and MCS scores. Patients who lived in rural areas had significantly poorer QOL at pollen peak, as measured by the mini-RQLQ (P = .002) and SF-12 PCS (P = .008). No influence of age, presence of an animal at home, or smoking status could be identified on any QOL scores. CONCLUSIONS: Being a woman, living in the countryside, and having a lower education level were all independent predictors of poorer QOL of SAR patients. These factors must be taken into account when interpreting QOL of patients with SAR. Further studies are needed to confirm these results.

Correlates of quality of life in patients with asthma.

BACKGROUND: Health-related quality of life (HRQOL) is a major outcome in asthma, but the relationships among HRQOL, characteristics of asthma, type of supervision, and sociodemographic characteristics of patients have not been thoroughly explored. OBJECTIVE: To identify major correlates of HRQOL in a survey of patients with asthma. METHODS: Patients with asthma were identified by their usual caregivers, either general practitioners or respiratory physicians. In a standardized interview, data were collected on patients' sociodemographic characteristics, medical history, medical resource use in the past 12 months, and asthma QOL. Intensity of asthma therapy was evaluated from the use of inhaled controllers and oral corticosteroids in the past 12 months, and number of asthma attacks during the same period was used as an indicator of level of asthma symptoms. RESULTS: Ninety-nine patients with asthma were identified (median age, 36 years; 62.6% women). In multivariate analysis, major correlates for lower HRQOL scores were having at least 5 asthma attacks and the number of medical visits in the past 12 months (P < .001 for both). Other significant positive associations were unemployment (P = .01) and female sex (P = .05), but not intensity of therapy, age, or type of asthma supervision (general practitioner vs respiratory physician). CONCLUSIONS: In this survey, HRQOL scores seem to be primarily related to asthma symptoms, as indicated by the number of attacks experienced by the patients and the frequency of medical contacts in a previous period. The relationships among HRQOL, therapy, and the determinants of control should be investigated in prospective studies.

Quality of life during pollen season in patients with seasonal allergic rhinitis with or without asthma.

OBJECTIVES: We studied the evolution of generic and rhinoconjunctivitis-specific quality of life (QOL) during pollen season in patients with isolated seasonal allergic rhinitis (SAR) and those with asthma and concomitant SAR (AS+SAR). Generic QOL between groups was also compared at pollen peak. METHODS: A prospective cohort study was conducted in Southern France in 2002. Outpatients aged 18-60, regularly visiting respiratory physicians for SAR, were recruited before the grass (grass cohort) or ragweed pollination period (ragweed cohort). Before the pollination period (baseline) and at peak pollination, patients completed French versions of the Mini Rhinoconjuctivitis Quality of Life Questionnaire (Mini-RQLQ) and physical and mental Short Form-12 (SF-12) scores (PCS and MCS) to determine rhinoconjunctivitis and generic QOL. RESULTS: Totals of 83 and 52 patients were included in the SAR and AS+SAR groups, respectively (mean age=35.4; 56.4% females). Mini-RQLQ scores indicated slightly worse QOL in the A+SAR group at inclusion, which significantly deteriorated at the time of pollen peak, both in the SAR (p<0.0001) and AS+SAR groups (p=0.003). In univariate analysis, significantly higher SF-12 PCS (meaning better QOL) were observed at pollen peak in the SAR compared with the AS+SAR group (p=0.0008), while the difference for SF-12 MCS was more limited (p=0.05). Results were confirmed in multivariable analyses adjusting for gender, allergy medication use at pollen peak, cohort of inclusion (grass/ragweed) and comorbid conditions. CONCLUSIONS: Significant deterioration in rhinoconjunctivitis-specific QOL was observed through the pollination period in patients with SAR and AS+SAR. At pollen peak, AS+SAR patients experienced significantly worse physical functioning than patients with SAR alone.
