Measuring Disease

5. Measuring Disease and Exposure

At the beginning of this text we noted four key aspects of epidemiology: its multidisciplinary nature, and its concern with populations, measurement, and comparison. As all empirical scientistis, epidemiologists devote a great deal of attention to issues of measurement – the application of numbers to phenomena. Every object of study – a disease, an exposure, an event, a condition – must be defi...

Measuring Spatial Dependence for Infectious Disease Epidemiology

Global spatial clustering is the tendency of points, here cases of infectious disease, to occur closer together than expected by chance. The extent of global clustering can provide a window into the spatial scale of disease transmission, thereby providing insights into the mechanism of spread, and informing optimal surveillance and control. Here the authors present an interpretable measure of s...

Measuring Disease Activity in Psoriatic Arthritis

Over the past decade, the assessment of the disease activity in psoriatic arthritis (PsA) has rapidly evolved in view of the need for valid, feasible, and reliable outcome measures that can be ideally employed in longitudinal cohorts, clinical trials, and clinical practice as well as the growing paradigm of tight disease control and treating to target in the management of PsA. This paper review...
