A web-based registry for patients with sarcoidosis.

ABSTRACT: Background/Objective:The objective is to present the development of a novel web-based patient registry for sarcoidosis. We describe recruitment efforts and assess efficacy of internet-based advertising on recruitment. Methods:"Worldwide Sarcoidosis Research Study (WISE)" started in 2011 under the domain www.sarcoidstudy.org. The registry includes thirteen patient-reported surveys about patient characteristics, diagnosis, and treatment. Effects of two internet-based advertising methods (geographically-broad versus geographically-targeted to high sarcoidosis search areas) on recruitment were analyzed with time series regression. Results:Since 2011, over 1500 participants have registered (82% whites, 9% African Americans, 5% mixed, 4% other), with 23% of participants providing saliva samples for DNA. Median age is 43 years (range 21-80). African Americans were more frequently recruited via support groups, while whites had a higher frequency of finding the registry via internet. Generalized internet-based advertising significantly improved recruitment in all demographic groups (p<0.001). However, a higher response rate to internet-based advertising was seen in whites compared to African Americans(p<0.001), females versus males(p=0.043), higher income categories(p=0.048), and increased education level(p<0.001). Targeting advertising campaigns to geographical areas with high internet-search patterns for sarcoidosis, with different demographics, was not effective in raising registry recruitment above baseline or increasing diversity. Conclusions:A web-based registry is an effective method for establishing a cohort of patients with sarcoidosis invested in clinical research with DNA specimens. Despite limitations, opportunities for research in patient-oriented outcomes and broad internet-based research methodology are possible. Our results demonstrate that web-based approaches to recruit study subjects need to be focused to match different target populations.

Project description:BACKGROUND:Hypertension guidelines recommend ambulatory blood pressure (ABP), central aortic pressure (CAP), and pulse wave velocity (PWV) as parameters for estimating blood pressure (BP) control and vascular impairment. Recent advances in technology have enabled devices to combine non-invasive estimation of these parameters over the 24-hour ABP monitoring. However, currently there is limited evidence on the usefulness of such an approach for routine hypertension management. OBJECTIVE:We recently launched an investigator-initiated, international, multicenter, observational, prospective study, the Vascular health Assessment Of The Hypertensive patients (VASOTENS) Registry, aimed at (1) evaluating non-invasive 24-hour ABP and arterial stiffness estimates (through 24-hour pulse wave analysis, PWA) in hypertensive subjects undergoing ambulatory blood pressure monitoring (ABPM) for clinical reasons; (2) assessing the changes in estimates following treatment; (3) weighing the impact of 24-hour PWA on target organ damage and cardiovascular prognosis; (4) assessing the relationship between arterial stiffness, BP absolute mean level and variability, and prognosis; and (5) validating the use of a 24-hour PWA electronic health (e-health) solution for hypertension screening. METHODS:Approximately 2000 subjects, referred to 20 hypertension clinics for routine diagnostic evaluation and follow-up of hypertension of any severity or stage, will be recruited. Data collection will include ABPM, performed with a device allowing simultaneous non-invasive assessment of 24-hour CAP and arterial stiffness (BPLab), and clinical data (including cardiovascular outcomes). As recommended by current guidelines, each patient will be followed-up with visits occurring at regular intervals (ideally every 6 months, and not less than once a year depending on disease severity). A Web-based telemedicine platform (THOLOMEUS) will be used for data collection. The use of the telemedicine system will allow standardized and centralized data collection, data validation by experts and counseling to remote centers, setup and maintenance of the Registry, and prompt data analysis. RESULTS:First follow-up results are expected to be available in the next 2 years. CONCLUSIONS:The results of the VASOTENS Registry will help define the normalcy thresholds for current and future indices derived from 24-hour PWA, according to outcome data, and will also provide supporting evidence for the inclusion of this type of evaluation in hypertension management.

Project description:The prevalence of sarcoidosis is known to be high in the Nordic countries. There are no recent research data on the incidence or prevalence of sarcoidosis in Finland. Our aim was to investigate the epidemiology of sarcoidosis in Finland through a retrospective registry-based study. We made an information request to the Hilmo database on patients who had been treated in Finnish specialised care with a main diagnosis related to sarcoidosis. Data were requested for the period 1 January-31 December for the years 2002, 2012 and 2022. In addition, we examined the age and gender distribution and regional differences in these variables between the five university hospital districts covering the whole of Finland. The incidence of sarcoidosis was 17‒19/100 000/year throughout the follow-up period. The prevalence of sarcoidosis in the ≥18-year-old population had risen from 85/100 000 in 2002-106/100 000 in 2022. There were considerable differences between university hospital districts: The highest prevalence rate was 170/100 000 in the Tampere University Hospital district in 2022, which was twice as high as in the Helsinki University Hospital district (84/100 000). The proportion of pulmonary sarcoidosis in all sarcoidosis cases decreased from 62% to 45% while the proportion of multiorgan sarcoidosis (D86.8) increased from 11% to 34%. The incidence of sarcoidosis was 15/100 000 and the prevalence was 82/100 000 in the age groups of ≥60 years in 2002. In 2022, the incidence in this same age group had risen to 20/100 000 and the prevalence to 109/100 000. In the ≥60-year-old population, the proportion of D86.8 increased from 11% to 35%. Sarcoidosis was a more common disease in Finland than in previous studies. Multiorgan sarcoidosis among the elderly has increased over the past 20 years. This might be explained by changes in environmental factors associated with sarcoidosis. Significant regional differences in prevalence might be partly explained by familial clustering.
