Summary Background and objectives Psoriasis is a common skin disorder with a high physical and psychological burden for patients. Up to 30% of the patients are candidates for a systemic treatment. The aim of this study was to describe the characteristics and the real‐world systemic treatment of psoriasis patients. Patients and methods This study was based on German medical claims data. A cross‐sectional analysis observed all psoriasis patients in 2020. A longitudinal analysis was conducted, addressing psoriasis patients who newly started a systemic treatment. Results In total, 116,507 prevalent psoriasis patients and 13,449 newly treated patients were followed. Of all prevalent patients, 15.2% received systemic treatment in 2020 (8.7% systemic corticosteroids). Of the newly treated patients, 95.2% started with conventional treatment (79.2% systemic corticosteroids), 4.0% with biologics and 0.9% with apremilast. The rate of treatment discontinuation/switch after one year was highest for corticosteroids (91.3%) and lowest for biologics (23.1%). Conclusions Around 15% of psoriasis patients in Germany received a systemic treatment, with > 50% of these prescribed systemic corticosteroids. Therefore, we conclude that systemic treatment is not in line with guideline recommendations in a substantial number of observed patients. The lowest discontinuation/switch rates for biologics support their wider use.

Background: Osteoporosis (OP) and its associated fractures have a significant impact on patients’ quality of life and are impacting their morbidity and mortality. For OP patients at high risk of fracture, guidelines recommend a pharmacological OP treatment. The aim of this study was to describe the real-world medication treatment of postmenopausal women with severe OP at high risk of fracture, their risk to experience a new fracture after having at least one previous fracture, and to assess the associated healthcare resource use (HCRU). Methods: This retrospective cohort study was based on anonymized German claims data (AOK PLUS). All included OP patients were female, ≥55 years old, and had a vertebral and/or femoral fracture. We conducted a cross-sectional analysis in 2018 and a longitudinal analysis, starting with an incident vertebral/femoral fracture (after or simultaneously with the first observed OP diagnosis). In both analyses, patient characteristics, rate of new incident fractures, OP treatment patterns, and HCRU associated with the treatment of patients were investigated. Results: In the cross-sectional setting, 12,180 patients with a mean age of 83.59 years were observed. Of these patients, 14.30% sustained at least one new incident fracture and 34.54% received a pharmaceutical OP treatment during 2018. In this year, 58.50% of the patients had at least one OP-related outpatient visit, and 26.35% had a fracture-related visit. In 160 patients (1.31%), at least one OP-related hospitalization was documented, and in 1,293 patients (10.62%) a fracture-related hospitalization in 2018. In the longitudinal setting, 10,323 patients with a mean age of 83.22 years were included. Of these, 18.96% experienced at least one new incident fracture within the first 12 months after the index fracture, and in total 30.85% in the entire follow-up period (mean 2.03 years). During the 12-month baseline period, 22.12% of the patients received an OP treatment. Three months after the index fracture, the proportion of treated patients remained at 22.30%. During the total follow-up time, 35.54% were prescribed with an OP treatment. Conclusion: We observed a considerable proportion of untreated patients and a high rate of subsequent fractures. The awareness for a proper risk assessment and the appropriate use of available treatments should be increased.

Dopamine receptor agonists (DAs) are commonly used to treat Parkinson's disease (PD) and restless legs syndrome (RLS). In certain situations, switching from oral DAs to rotigotine transdermal patch may be beneficial for the patient (e.g., optimal symptom control/side effects/perioperative management, preference for once-daily/non-oral administration, RLS augmentation treatment). Areas covered: This narrative review summarizes available data on DA dose equivalency, dose conversions, switching schedules, safety, tolerability, efficacy and patient treatment preferences of switching from oral DAs to rotigotine (and vice versa) in patients with PD/RLS. The studies were identified in a PubMed search (up to 8 November 2016) using terms ('dopamine receptor agonist' OR 'rotigotine') AND 'switch'. Expert commentary: Randomized controlled studies often do not address the challenges clinicians face in practice, e.g., switching medications within the same class when dosing is not a one-to-one ratio. The authors describe three open-label studies in PD where oral DAs were successfully switched to rotigotine, and review three studies in RLS where oral DAs/levodopa were switched to rotigotine. Finally, the authors provide a suggested tool for switching from oral DAs to rotigotine, which includes dose conversion factors and switching schedules. The authors' view is that low-dose oral DAs (equivalent to ≤8 mg/24 h rotigotine) may be switched overnight.
