In the past years, several factors such as evidence-based healthcare culture, quality-linked incentives, and patient-centered actions, associated with an important increase of financial constraints and pressures on healthcare budgets, resulted in a growing interest by policy-makers in enlarging pharmacists’ roles in care. Numerous studies have demonstrated positive therapeutic outcomes associated with pharmaceutical services in a wide array of diseases. Yet, the evidence of the economic impact of the pharmacist in decreasing total health expenditures, unnecessary care, and societal costs relies on well-performed, reliable, and transparent economic evaluations, which are scarce. Pharmacoeconomics is a branch of health economics that usually focuses on balancing the costs and benefits of an intervention towards the use of limited resources, aiming at maximizing value to patients, healthcare payers and society through data driven decision making. These decisions can be guide by a health technology assessment (HTA) process that inform governmental players about medical, social, and economic implications of development, diffusion, and use of health technologies – including clinical pharmacy interventions. This paper aims to provide an overview of the important concepts in costing in healthcare, including studies classification according to the type of analysis method (e.g. budget-impact analysis, cost-minimization analysis, cost-effectiveness analysis, cost-utility analysis), types of costs (e.g. direct, indirect and intangible costs) and outcomes (e.g. events prevented, quality adjusted life year - QALY, disability adjusted life year - DALY). Other key components of an economic evaluation such as the models’ perspective, time horizon, modelling approaches (e.g. decision trees or simulation models as the Markov model) and sensitivity analysis are also briefly covered. Finally, we discuss the methodological issues for the identification, measurement and valuation of costs and benefits of pharmacy services, and suggest some recommendations for future studies, including the use of Value of Assessment Frameworks.

Objective Copayment policies aim to reduce the burden of medication expenditure but may affect adherence and generate inequities in access to healthcare. The objective was to evaluate the impact of two copayment measures on initial medication non-adherence (IMNA) in several medication groups and by income level. Design A population-based study was conducted using real-world evidence. Setting Primary care in Catalonia (Spain) where two separate copayment measures (fixed copayment and coinsurance) were introduced between 2011 and 2013. Participant Every patient with a new prescription issued between 2011 and 2014 (3 million patients and 10 million prescriptions). Outcomes IMNA was estimated throughout dispensing and invoicing information. Changes in IMNA prevalence after the introduction of copayment policies (immediate level change and trend changes) were estimated through segmented logistic regression. The regression models were stratified by economic status and medication groups. Results Before changes to copayment policies, IMNA prevalence remained stable. The introduction of a fixed copayment was followed by a statistically significant increase in IMNA in poor population, low/middle-income pensioners and low-income non-pensioners (OR from 1.047 to 1.370). In high-income populations, there was a large statistically non-significant increase. IMNA decreased in the low-income population after suspension of the fixed copayment and the introduction of a coinsurance policy that granted this population free access to medications (OR=0.676). Penicillins were least affected while analgesics were affected to the greatest extent. IMNA to medications for chronic conditions increased in low/middle-income pensioners. Conclusion Even nominal charge fixed copayment may generate inequities in access to health services. An anticipation effect and expenses associated with IMNA may have generated short-term costs. A reduction in copayment can protect from non-adherence and have positive, long-term effects. Copayment scenarios could have considerable long-term consequences for health and costs due to increased IMNA in medication for chronic physical conditions.

Mental disorders have a huge impact on the European population. Two of the main causes of this impact are stigma and discrimination. The aim of this paper is to assess the stigma regarding mental disorder in Catalonia and to explore factors associated with stigma. Cross-sectional population-based survey of a representative sample of non-institutionalized adult population (n = 1872). We evaluated attitudes (CAMI: Authoritarianism, Benevolence and Support to Community Mental Health care) and intended behaviour (RIBS) regarding mental disorder and experience of discrimination. Higher scores showed more favourable attitudes and intended behavior. Mean values and percentiles of the scales were calculated. Multivariable regression models were used to assess factors associated with stigma. Mean authoritarianism, benevolence and support to community mental health scores corresponded to the 66th, 90th and 78th percentile, respectively. Mean RIBS score corresponded to the 76th percentile. More favourable attitudes were associated with being male, younger, having a higher education, being Spanish, having suffered a mental disorder and having contact with a person with a mental disorder.Similarly, more favourable intended behaviour was associated with being younger, having secondary education, having Spanish nationality, belonging to a higher social class and having contact with a person with a mental disorder. People with depression or anxiety showed lower discrimination experiences than people with other mental disorders. The levels of stigma were generally low among the Catalan population. However, efforts should be made to decrease stigma related to authoritarianism. Interventions addressed to reducing stigma should take into account other mental disorders apart from depression or anxiety. They should be focused on older, immigrant population, people with lower educational attainment and people who have not had contact with someone with a mental disorder.

Reducing public stigma could improve patients’ access to care, recovery and social integration. The aim of the study was to evaluate a mass media intervention, which aimed to reduce the mental health, related stigma among the general population in Catalonia (Spain). We conducted a cross-sectional population-based survey of a representative sample of the Catalan non-institutionalized adult population (n = 1019). We assessed campaign awareness, attitudes to people with mental illness (CAMI) and intended behaviour (RIBS). To evaluate the association between campaign awareness and stigma, multivariable regression models were used. Over 20% of respondents recognized the campaign when prompted, and 11% when unprompted. Campaign aware individuals had better attitudes on the benevolence subscale of the CAMI than unaware individuals (P = 0.009). No significant differences in authoritarianism and support for community mental health care attitudes subscales were observed. The campaign aware group had better intended behaviour than the unaware group (P < 0.01). The OBERTAMENT anti-stigma campaign had a positive impact to improve the attitudes and intended behaviour towards people with mental illness of the Catalan population. The impact on stigma was limited to attitudes related to benevolence. A wider range of anti-stigma messages could produce a stronger impact on attitudes and intended behaviour.
