Purpose The COVID‐19 pandemic had an impact on health care, with disruption to routine clinical care. Our aim was to describe changes in prescription drugs dispensing in the primary and outpatient sectors during the first year of the pandemic across Europe. Methods We used routine administrative data on dispensed medicines in eight European countries (five whole countries, three represented by one region each) from January 2017 to March 2021 to compare the first year of the COVID‐19 pandemic with the preceding 3 years. Results In the 10 therapeutic subgroups with the highest dispensed volumes across all countries/regions the relative changes between the COVID‐19 period and the year before were mostly of a magnitude similar to changes between previous periods. However, for drugs for obstructive airway diseases the changes in the COVID‐19 period were stronger in several countries/regions. In all countries/regions a decrease in dispensed DDDs of antibiotics for systemic use (from −39.4% in Romagna to −14.2% in Scotland) and nasal preparations (from −34.4% in Lithuania to −5.7% in Sweden) was observed. We observed a stockpiling effect in the total market in March 2020 in six countries/regions. In Czechia the observed increase was not significant and in Slovenia volumes increased only after the end of the first lockdown. We found an increase in average therapeutic quantity per pack dispensed, which, however, exceeded 5% only in Slovenia, Germany, and Czechia. Conclusions The findings from this first European cross‐national comparison show a substantial decrease in dispensed volumes of antibiotics for systemic use in all countries/regions. The results also indicate that the provision of medicines for common chronic conditions was mostly resilient to challenges faced during the pandemic. However, there were notable differences between the countries/regions for some therapeutic areas.

BackgroundAssociation between psoriasis severity and cerebro- and cardiovascular comorbidities has rarely been investigated.AimWe aimed to investigate differences in cerebro- and cardiovascular comorbidities by psoriasis severity.Materials and methodsUsing Swedish nationwide health-care registers, new adult users of anti-psoriatic drugs (2007–2013) with a recorded diagnosis of psoriasis/psoriatic arthritis or a filled prescription for calcipotriol were included. Psoriasis severity was based on the type of anti-psoriatic treatment (topical/mild, non-biologic systemic/moderate-to-severe, and biologics/ severe). Age standardized prevalence rates of cerebro- and cardiovascular comorbidities and their risk factors were compared between the groups.ResultsWe found that severe psoriasis patients (N=2147) were younger than moderate-to-severe (N=11,919) or mild (N=70,796) patients (median 44, 52, and 55 years). Prevalence of hypertension was 29.9%, 32.6%, and 36.5%, myocardial infarction was 2.5%, 2.3%, and 1.8%, and stroke was 2.4%, 2.2%, and 1.1% in mild, moderate-to-severe, and severe psoriasis patients, respectively. Diabetes prevalence was 7.6% in mild, 8.0% in moderate-to-severe, and 10.7% in severe psoriasis.ConclusionMyocardial infarction and stroke were less common in patients with severe psoriasis while, despite being younger, they had a higher prevalence of diabetes and hypertension.

The divergent results with regard to parity and PBC risk when using sister and population controls suggest that the influence of childbearing may be modified by genotype. Selection bias when using different control groups must also be considered.

ObjectiveTo investigate risk of premenopausal and postmenopausal breast cancer among Multiple Sclerosis (MS) patients, considering tumor stage.MethodsThe Swedish Patient Register identified 19,330 women with MS between 1968 and 2012, matched individually with a cohort of 193,458 without MS. Matching variables were year of birth, sex, region of residence and vital status at the time of diagnosis. The cancer register identified 471 and 5,753 breast cancer cases among the MS and non-MS cohorts, respectively. Cox proportional hazard models estimated hazard ratios (HR) and 95% confidence intervals (CI) for premenopausal and postmenopausal breast cancer.ResultsOverall risk of postmenopausal breast cancer was 13% higher among MS patients compared with women without MS (HR = 1.13, 95% CI 1.02–1.26). Stratified analyses showed that the risk was statistically significantly increased in women diagnosed between 1968 and 1980 and those who were diagnosed at age 65 or older age. We observed a non-statistically significant risk only for stage 0–1 postmenopausal breast cancer (HR = 1.17, 95% CI 0.93–1.48). MS was not associated with premenopausal breast cancer.ConclusionThe modest increased risk of postmenopausal breast cancer in women with MS may be due to surveillance bias, where contact with health services for one disease increases the risk of a second diagnosis being recorded.
