Psoriasis (Pso) is a chronic inflammatory skin disease, and up to 30% of Pso patients develop psoriatic arthritis (PsA), which can lead to irreversible joint damage. Early detection of PsA in Pso patients is crucial for timely treatment but difficult for dermatologists to implement. We, therefore, aimed to find disease-specific immune profiles, discriminating Pso from PsA patients, possibly facilitating the correct identification of Pso patients in need of referral to a rheumatology clinic. The phenotypes of peripheral blood immune cells of consecutive Pso and PsA patients were analyzed, and disease-specific immune profiles were identified via a machine learning approach. This approach resulted in a random forest classification model capable of distinguishing PsA from Pso (mean AUC = 0.95). Key PsA-classifying cell subsets selected included increased proportions ofdifferentiated CD4+CD196+CD183-CD194+ and CD4+CD196-CD183-CD194+ T-cells and reduced proportions of CD196+ and CD197+ monocytes, memory CD4+ and CD8+ T-cell subsets and CD4+ regulatory T-cells. Within PsA, joint scores showed an association with memory CD8+CD45RACD197- effector T-cells and CD197+ monocytes. To conclude, through the integration of in-depth flow cytometry and machine learning, we identified an immune cell profile discriminating PsA from Pso. This immune profile may aid in timely diagnosing PsA in Pso.

Background: Despite the large availability of caregivers, there are no standardized care pathways for patients with acne. This increases the risk of ineffective care and unnecessary medicalizing. To better understand how to provide effective, efficient, and patient-satisfying care, it is necessary to gain insights into the patient journey through acne healthcare services. Objective: To explore the patient journeys, assessed by a series of consecutive steps through acne healthcare. Methods: A cross-sectional survey was conducted among Dutch individuals with acne. Results: A total of 371 respondents completed the questionnaire. Data revealed 58 different pathways through acne healthcare services. Patient with severe acne had a stronger tendency to seek professional care than those with mild acne (p<.05). The highest proportion of clinically relevant improvement was found in patients treated by dermatologists, compared to respondents treated by beauticians, p¼.023 and dermal therapists, p¼.018. Conclusions: Mapping the patient journeys contributed to a better understanding of the gap between professional guidelines and the experiences of patients. Identifying these areas of care implies that there is potential to bring acne care services more in line with the patients’ needs. Further research is recommended; for example by comparing the clinical treatment outcomes of multiple sequences of caregivers.

Abstract Background: Many countries in Europe have implemented managed competition and patient choice during the last decade. With the introduction of managed competition, health insurers also became an important stakeholder. They purchase services on behalf of their customers and are allowed to contract healthcare providers selectively. It has, therefore, become increasingly important to take one's insurance into account when choosing a provider. There is little evidence that patients make active choices in the way that policymakers assume they do. This research aims to investigate, firstly, the role of patients in choosing a healthcare provider at the point of referral, then the role of the GP and, finally, the influence of the health insurer/insurance policies within this process. Methods: We videotaped a series of everyday consultations between Dutch GPs and their patients during 2015 and 2016. In 117 of these consultations, with 28 GPs, the patient was referred to another healthcare provider. These consultations were coded by three observers using an observation protocol which assessed the role of the patient, GP, and the influence of the health insurer during the referral. Results: Patients were divided into three groups: patients with little or no input, patients with some input, and those with a lot of input. Just over half of the patients (56%) seemed to have some, or a lot of, input into the choice of a healthcare provider at the point of referral by their GP. In addition, in almost half of the consultations (47%), GPs inquired about their patients' preferences regarding a healthcare provider. Topics regarding the health insurance or insurance policy of a patient were rarely (14%) discussed at the point of referral. Conclusions: Just over half of the patients appear to have some, or a lot of, input into their choice of a healthcare provider at the point of referral by their GP. However, the remainder of the patients had little or no input. If more patient choice continues to be an important aim for policy makers, patients should be encouraged to actively choose the healthcare provider who best fits their needs and preferences.
