Background: This study describes the prevalence of non-steroidal anti-inflammatory drug (NSAID) use, and analyses prescribing patterns of NSAIDs and associated gastroprotection. Methods: The study population consisted of 5650 workers at the General Motors automobile assembly plant in Zaragoza, Spain. NSAID prescription data for 2014 were obtained from the prescription database of Aragon (Spain). NSAID consumption was determined based on the number of defined daily doses purchased per year. Heavy NSAIDs users were identified using Lorenz curves. Results: NSAID use in the cohort was high (40.7% of workers, 95% CI 39.4–41.9). The prescription of proton pump inhibitors increased with age. Gastrointestinal protection was lacking in some participants who were being treated with drugs associated with a high risk of gastrointestinal bleeding. Heavy NSAID users (defined as those above the 95th percentile of consumption), accounted for 26% of total DDDs, and consumed a greater proportion of coxibs than non-heavy users. Conclusions: The rate of NSAID consumption in the cohort was high. To reduce the risk of gastrointestinal complications, monitoring and adequate gastroprotection are essential in patients who are prescribed NSAIDs for long periods of time or who are treated concomitantly with drugs that increase the risk of gastrointestinal bleeding.

Aims: This study aimed to analyse the initiation adherence phase to lipid‐lowering therapy for primary prevention of cardiovascular disease in a Spanish population aged 70 years or older. The secondary objective was to identify the determinants of initiation and early discontinuation.Methods: This was an observational study conducted in the CArdiovascular Risk factors for HEalth Service research (CARhES) cohort. People aged 70 and older with a first prescription of a lipid‐lowering drug and without a previous major adverse cardiovascular event (MACE) were selected (2018–2021). Data on sociodemographics, clinical conditions, drugs and use of health services were collected from clinical and administrative electronic databases. The study population was classified into: non‐initiation, early discontinuation (i.e., discontinuation after the first dispensing) and initiation with more than one dispensing. Their characteristics were compared. Determinants of initiation and early discontinuation were explored.Results: Among the 15 019 people studied, 80.2% initiated the medication, 11.2% showed an early discontinuation and 8.6% were non‐initiators. An older age or conditions such as dementia, diabetes or depression reduced the likelihood of initiation, while obesity and a high pharmacological burden increased it. People over 90 years of age or those prescribed a statin in combination were more likely to have an early discontinuation.Conclusions: Non‐initiation and early discontinuation are common among older people prescribed lipid‐lowering drugs as primary prevention of cardiovascular disease for the first time. The presence of chronic pathologies other than cardiovascular ones should be considered when assessing whether or not to prescribe these drugs in the elderly.

We sought to identify specific profiles of new lipid-lowering drug users based on adherence to a healthy lifestyle and persistence with medication, and to characterize co-morbidities, co-treatments, and healthcare utilization for each of the profiles identified. Observational study in 517 participants in the Aragon Workers’ Health Study (AWHS) without previous cardiovascular disease (CVD) and who initiated lipid-lowering therapy. Data were collected from workplace medical examinations and administrative health databases (2010–2018). Using cluster analysis, we identified distinct patient profiles based on persistence with therapy and lifestyle. We then compared characteristics, morbidity, and healthcare utilization across clusters. Participants were aggregated into four clusters based on persistence with therapy, smoking status, adherence to Mediterranean diet, and physical activity. In cluster 1 (n = 113), comprising those with a healthiest lifestyle (14.2% smokers, 84.0% with medium-high adherence to Mediterranean diet, high physical activity), 16.8% were persistent. In cluster 3 (n = 108), comprising patients with the least healthy lifestyle (100% smokers, poor adherence to the Mediterranean diet, low level of physical activity), all were non-persistent. Clusters 2 (n = 150) and 4 (n = 146) both comprised patients with intermediate lifestyle behaviors, but differed in terms of persistence (100 and 0%, respectively). Compared with other clusters, the burden of morbidity, cardiovascular score, and healthcare utilization were lower in cluster 1. The healthy adherer effect was only observed in new lipid-lowering drug users of certain profiles. Furthermore, we found that differences in adherence to lifestyle and medication recommendations for CVD prevention influenced morbidity burden and healthcare utilization.

In this study, we analyzed the effectiveness of statin therapy for the primary prevention of cardiovascular disease (CVD) in low- and medium-risk patients. Using observational data, we estimated effectiveness by emulating a hypothetical randomized clinical trial comparing statin initiators with statin non-initiators. Two approaches were used to adjust for potential confounding factors: matching and inverse probability weighting in marginal structural models. The estimates of effectiveness were obtained by intention-to-treat and per-protocol analysis. The intention-to-treat analysis revealed an absolute risk reduction of 7.2 (95% confidence interval (CI95%), −6.6–21.0) events per 1000 subjects treated for 5 years in the matched design, and 2.2 (CI95%, −3.9–8.2) in the marginal structural model. The per-protocol analysis revealed an absolute risk reduction of 16.7 (CI95%, −3.0–36) events per 1000 subjects treated for 5 years in the matched design and 5.8 (CI95%, 0.3–11.4) in the marginal structural model. The indication for statin treatment for primary prevention in individuals with low and medium cardiovascular risk appears to be inefficient, but improves with better adherence and in subjectvs with higher risk.

Fundamento: La utilización de nuevos fármacos ha aumentado de forma importante en los últimos años. El objetivo de este trabajo es conocer la utilización de novedades farmacéuticas en un área de salud de Zaragoza, describir cuales son las más utilizadas y su evolución en el tiempo y analizar las características de los centros que se asocian con un mayor uso de estos medicamentos. Métodos: Se trata de un estudio descriptivo en el que se analizaron todas las dispensaciones de 50 nuevos principios activos comercializados entre el 1-1-2000 y el 31-12-2003 en un área de salud. Se calculó el porcentaje de utilización de novedades durante el primer año de su comercialización, en cada centro de atención primaria, y se analizaron las características de los centros que se asociaban con mayor grado de innovación. Resultados: El 76% de los 50 nuevos fármacos comercializados eran escasamente innovadores respecto a los ya existentes. Las diez novedades más prescritas comenzaron a utilizarse en el primer cuatrimestre tras su aparición en el mercado. El porcentaje de utilización de novedades respecto al total de fármacos prescritos en los centros de salud estudiados osciló entre el 0,3% y el 1,18%. En el análisis efectuado por centros, el «gasto por paciente» y las «consultas por médico» se correlacionaron positivamente con un mayor uso de medicamentos nuevos, mientras que el porcentaje de pensionistas presentó una relación inversa. Conclusiones: Existe una gran variabilidad en el porcentaje de utilización de novedades farmacológicas entre los centros de atención primaria. Los centros con mayor número de consultas por facultativo son los que tienden a incorporar los nuevos medicamentos con mayor facilidad.

The aim of this study was to know the prevalence and severity of COVID-19 in patients treated with long-term macrolides and to describe the factors associated with worse outcomes. A cross-sectional study was conducted in Primary Care setting. Patients with macrolides dispensed continuously from 1 October 2019 to 31 March 2020, were considered. Main outcome: diagnosis of coronavirus disease-19 (COVID-19). Secondary outcomes: symptoms, severity, characteristics of patients, comorbidities, concomitant treatments. A total of 3057 patients met the inclusion criteria. Median age: 73 (64–81) years; 55% were men; 62% smokers/ex-smokers; 56% obese/overweight. Overall, 95% of patients had chronic respiratory diseases and four comorbidities as a median. Prevalence of COVID-19: 4.8%. This was in accordance with official data during the first wave of the pandemic. The most common symptoms were respiratory: shortness of breath, cough, and pneumonia. Additionally, 53% percent of patients had mild/moderate symptoms, 28% required hospital admission, and 19% died with COVID-19. The percentage of patients hospitalized and deaths were 2.6 and 5.8 times higher, respectively, in the COVID-19 group (p < 0.001). There was no evidence of a beneficial effect of long-term courses of macrolides in preventing SARS-CoV-2 infection or the progression to worse outcomes in old patients with underlying chronic respiratory diseases and a high burden of comorbidity.
