Here we have a basic SEIR model and we will investigate what changes would be appropriate for modelling the 2019 Coronavirus.

The initial parametrization is based on the suggested current data. The initial population is set for Catalonia.

Addition of Incident Reporting and Prevention Interventions to a simple error chain of medication errors for patients in hospital IM-10113 

This model shows the dynamics of use of a new medical technology based on its scope of use and perceived relative benefit. The technology needs cumulative usage to fix its glitches, and the benefits will be diluted  as the scope of use widens.

This is a simpler version of Insight 649 showing the flow of Older People among the Community Hospital and Aged Care Residences

WIP Stock Flow representation of Panarchy Adaptive Cycles

A simple medical workforce model of doctor flows, population and service growth.

A causal loop diagram of thermostat action  including conversions between heat and temperature and outside temperature. (Insight 394) extended to include fiddling with the thermostat controls based on differential house and outside temperatures. The simulation model is at Insightmaker 393.

The dynamics of health care spending, or why it keeps growing. Adapted from Fig 7.6 p154 of Sauwakon Ratanawijitrasin's PhD thesis SUNY Albany 1993 "The dynamics of health care finance: A feedback view of system behavior."

Black and white Unfolding Stock and flow map version of IM 1498

From Evans RG and Stoddardt GL  1990 paper Soc Sci Med 31(12)1347-63 , also published in a book by Evans, Barer and Marmor, Why are some people healthy and others not?: The determinants of population health. This is a steady state model of IM-424 that ignores deaths and population increase. This is extended in IM-451

This is a launchpad for patient flow insights for flows through the emergency department and hospital, including the broader community context. It also includes links to other insights relevant to ED flow improvement.
