Does a cardiovascular event change adherence to statin treatment in patients with type 2 diabetes? A matched cohort design.

OBJECTIVE: To be effective, adherence to statin treatment is essential. We assessed the effect of an apparent first cardiovascular event on statin adherence rates in type 2 diabetes patients. RESEARCH DESIGN AND METHODS: A matched cohort study was conducted among type 2 diabetes patients initiating statin treatment for primary prevention in the Groningen University IADB.nl pharmacy database. Patients who had a drug-treated cardiovascular event (index date) after statin initiation were matched to a reference patient without such an event with similar gender, age at statin initiation, initiation date, follow-up period and adherence level before the event. Adherence rates were measured as percentages of days covered (PDC), and shifts in adherence levels (non-adherent/partially adherent/fully adherent) and rates around the event were evaluated. RESULTS: We could match 375 of the 855 eligible index patients to a reference patient. Index patients had on average a PDC of 81% after the index date; reference patients had a PDC of 71% (p < 0.001) while both had a PDC of 79% before the index date. Index patients were 4.5 times more likely than reference patients to shift from non-adherent to fully adherent (95% CI 1.1-18.8) and 1.8 times more likely to shift from partially adherent to fully adherent (95% CI 1.2-2.6). In the index group, 26% of patients became more adherent after the first cardiovascular event. In contrast, 20% of patients became less adherent. LIMITATIONS: Medication proxies were used, which could have caused misclassification. Furthermore, a substantial group of index patients could not be matched to a reference patient due to small ranges in matching criteria. CONCLUSIONS: The occurrence of a drug-treated cardiovascular event appeared to avert the declining statin adherence rate observed in diabetes patients without such an event. On the other hand, one in five patients became less adherent after the event, indicating that there are still important benefits to achieve.

Proactive pharmaceutical care interventions decrease patients' nonadherence to osteoporosis medication.

UNLABELLED: Using a protocolled intervention program, pharmacists can decrease nonadherence to osteoporosis medication, by continuous monitoring and tailored counseling sessions, starting at treatment initiation. In the usual care group, 32.8% of patients initiating osteoporosis medication discontinued or were nonadherent, compared to 19.0% of patients in the intervention group. PURPOSE: While community pharmacies have been shown to offer a promising platform for osteoporosis management in patients with osteoporosis, more research is needed to determine pharmacists' effects on improving adherence. The aim of this study was to determine the effects of a community pharmacists' intervention program on the 1-year discontinuation and nonadherence rates of patients initiating osteoporosis medication. METHODS: This intervention study included 937 patients, recruited from 13 Dutch community pharmacies, initiating osteoporosis medication. The intervention group (N = 495), received the Medication Monitoring and Optimization (MeMO) intervention, comprising of continuous monitoring of patients' adherence to their osteoporosis medication and tailored counseling sessions with nonadherent patients. Results were compared to an internal (n = 442) reference group, receiving usual pharmacy care. Primary study outcomes were therapy discontinuation and nonadherence; results were adjusted for potential confounders using Cox proportional hazard analysis. Secondary outcome was patients' satisfaction. RESULTS: In the usual care group, 32.8% of patients initiating osteoporosis medication discontinued or were nonadherent, compared to 19.0% of patients in the intervention group (P < 0.001). Ninety-three percent of the respondents were satisfied with the pharmacies' services provided. Notably, 31% mentioned that the pharmacy was the only place where they received information on various aspects of administration and acting of their medication. CONCLUSION: Pharmacists can decrease nonadherence and discontinuation with osteoporosis medication by providing tailored counseling sessions and continuous monitoring of drug use. Pharmaceutical care programs, such as MeMO, contribute to more optimal use of osteoporosis medication.

COPD in the working age population: the economic impact on both patients and government.

OBJECTIVES: To explore the full economic impact, on both patients and government, as a result of COPD in the working age population. METHODS: The economic impact of COPD due to medical treatment, impaired productivity and early retirement was assessed in a cross sectional cost analysis of the Dutch COPD population aged 45-64 years. The costing year was 2009 and input parameters were derived from both national data sources and the international COPD uncovered survey. RESULTS: While direct medical costs for COPD patients of working age were relatively low (€ 91 million), the amount of lost productivity (income) due to early retirement (€ 223 million) exceeded over two times their medical costs. In addition, costs for the government were considerable because of lost tax revenues (€ 77 million) and COPD related disability pensions paid (€ 180 million). Apart from lost productivity due to early retirement, costs due to impaired productivity for working COPD patients were € 63 million. CONCLUSIONS: The costs of COPD for both patients of working age as for the government were considerable, making this population a priority for prevention and intervention programs of healthcare providers, employers and government.

The pharmacists' potential to provide targets for interventions to optimize pharmacotherapy in patients with asthma.

BACKGROUND: Despite of pharmacists' specialized knowledge of medication and his/her regular contact with patients, the expertise of the pharmacist may not be used enough yet. Furthermore, the potential of pharmacy dispensing data is underestimated. OBJECTIVE: To provide targets for tailored interventions in asthma patients and to illustrate the potential value of pharmacists in the identification of these targets using individual pharmacy dispensing data. SETTING: We performed a cross sectional retrospective analysis assessing the quality of asthma patients' pharmacotherapeutic treatment. METHOD: Drug dispensing data from 2008 to 2009 were retrieved from a Dutch pharmacy database. All asthma patients were screened for potential suboptimal pharmacotherapy in 2009. Results were projected to a single community pharmacy to provide an estimate of the number of patients eligible for potential interventions. MAIN OUTCOME MEASURES: (1) frequent use of short-acting ß-agonists without preventive medication, (2) concomitant use of ß-blockers, (3) multiple short courses of oral corticosteroids without using inhaled corticosteroids and 4) use of long-acting ß-agonist without inhaled corticosteroids. RESULTS: A total of 8,504 patients were eligible for analysis of the quality of their asthma treatment. 20.9 % of all asthma patients used >100 DDD short-acting ß-agonists per year, whereas between 21.2 % (≥ 400 DDD) and 31.4 % (100-199 DDD) of these patients did not receive preventive medication. Approximately 5.2 % of the asthma patients are using ß-blockers concomitantly and 21.8 % of them received non-cardioselective ß-blockers. 6.3 % of the asthma patients received two or more oral courses of corticosteroids in 2008 and 17.4 % of these patients did not receive inhaled corticosteroids in 2009. 2.9 % of the patients used a long-acting ß-agonists without inhaled corticosteroids. 8.4 % of the asthma patients using both long-acting ß-agonists and inhaled corticosteroids received these drugs in two separate inhalers. We estimated that about 400 asthma patients could be identified in an average pharmacy population (8,000 patients) and 33 (95 % CI 22-44) of these patients would be eligible for interventions. CONCLUSION: This study shows the potential for pharmacists to use their own pharmacy records to identify suboptimal therapy of asthma patients, who may be targets for tailored interventions.

Meta-analysis using individual patient data: efficacy and durability of topical alicaforsen for the treatment of active ulcerative colitis.

BACKGROUND: The antisense ICAM-1 inhibitor alicaforsen has been studied in four phase 2 studies in ulcerative colitis (UC). Recruited patients varied as to the extent of their colitis and in the severity of disease at entry. AIM: To investigate the efficacy of alicaforsen enema in specific UC populations. Efficacy was analysed for short-term (week 6-10) and long-term (week 30) outcomes compared with either placebo or a high-dose mesalazine (mesalamine) enema in patients with disease extent up to 40 cm from the anal verge in patients with moderate or severe disease, and in patients with both of these features. METHODS: Individual patient data meta-analyses of 200 patients from four phase 2 studies evaluating nightly alicaforsen 240 mg enema and comparators. Patient data were pooled and analysed in a single data set. Continuous outcomes were evaluated using anova; dichotomous outcomes were evaluated using Pearson chi-square or Fisher's exact tests. RESULTS: Alicaforsen showed superior efficacy vs. placebo in: patients with disease extent up to 40 cm, patients with moderate and severe disease and especially when both those conditions were satisfied. In these patient groups, mesalazine also showed short-term efficacy. At week 30, however, the efficacy of mesalazine waned and alicaforsen became significantly more efficacious. CONCLUSIONS: This post hoc meta-analysis showed that alicaforsen is effective in patients with active UC, especially in patients with distal disease, which is of moderate/severe activity. The efficacy of alicaforsen was durable in these sub-groups, suggesting a disease-modifying effect. This analysis suggests that alicaforsen enema may offer an effective, potentially durable response in moderate/severe distal active UC.
