Second-Order Medicine and Second-Order Healthcare: Functional State Spaces, Networked Care Paths, and Propagation-First Governance

This paper introduces Second-Order Medicine (SOMed) and Second-Order Healthcare(SOHc), a unified discipline built on Human-Centric Functional Modeling (HCFM). Drawingon a set of draft papers (in the accompanying collection) that articulate hierarchies offunctional systems—from cellular regulation through sensorimotor control to cognition andsocial function—we assess whether these can be represented as a hierarchy of functionalstate spaces (FSS) and whether healthcare processes can be formalized as paths through aconceptual space of interventions and transitions. We argue that both are feasible and fruitful.Inspired by second-order frameworks in adjacent sciences, we elevate cross-level mappingsand cross-service care pathways to first-class objects governed by embedded, artifact-levelmetrics: Bridge Pass-Rate (BPR), Cycle-Loss, Minimum Description Length (MDL) deltas,and Overlap Residuals. In doing so, we connect HCFM to systems biology (Kitano, 2002;Barab´asi et al., 2011), developmental dynamics (Thelen & Smith, 1994), predictive processingand active inference (Friston, 2010; Clark, 2013), learning health systems (Friedman et al.,2010; Institute of Medicine, 2013), and value-based and network-integrated care (Porter& Teisberg, 2006; Vanhaecht et al., 2010). We show how network effects among careprocesses can be harnessed to increase outcomes and reliability, provided that second-ordermeasurement and governance ride with the artifacts of care and computation.
