Modular structures and the delivery of inpatient care in hospitals: a Network Science perspective on healthcare function and dysfunction.

Background: Reinforced by the COVID-19 pandemic, the capacity of health systems to cope with increasing healthcare demands has been an abiding concern of both governments and the public. Health systems are made up from non-identical human and physical components interacting in diverse ways in varying locations. It is challenging to represent the function and dysfunction of such systems in a scientific manner.

The Maternal Looking Guide: a perinatal clinical tool to support the emerging mother-infant relationship'.

Background: This study explores maternal looking - the unidirectional looking by a mother at her newborn - as a precursor to mother-infant gaze.

Methods: Phase 1 used video as a means of detailed and disciplined observation to examine how mothers look at their newborns (n = 13). Using an iterative design, intensive analysis identified and categorised patterns of looking and looking-related behaviours.

Hospital's instability wedges.

In this study, we define a hospital congestion episode as a situation where the number of new patients needing admission is greater than the number of available beds in the hospital, and investigate the likelihood that the current day's midnight occupancy will exceed any specified threshold level. We demonstrate that this measure of risk exhibits a characteristic sensitivity phenomenon that we have named as hospital's instability wedge. In particular, it is seen that frequently even small changes in the numbers of patients admitted or discharged can dramatically change the risk of exceeding the threshold, thereby changing the risk of subsequent congestion episodes.

Screening for important unwarranted variation in clinical practice: a triple-test of processes of care, costs and patient outcomes.

Objective Unwarranted variation in clinical practice is a target for quality improvement in health care, but there is no consensus on how to identify such variation or to assess the potential value of initiatives to improve quality in these areas. This study illustrates the use of a triple test, namely the comparative analysis of processes of care, costs and outcomes, to identify and assess the burden of unwarranted variation in clinical practice. Methods Routinely collected hospital and mortality data were linked for patients presenting with symptoms suggestive of acute coronary syndromes at the emergency departments of four public hospitals in South Australia.
