The quantitative approach to healthcare system resilience.

Method	Quantification of resilience in healthcare systems	Feature equations	Literature sources
Scorecard model	In terms of hospital geographic information, structural safety, nonstructural safety, and medical functional safety, 145 evaluation indicators were established	N.A	[55]
	There are 43 evaluation indicators in eight areas: hospital safety, emergency leadership and cooperation, emergency preparedness, disaster material management, emergency personnel, emergency training and drills, critical emergency response capacity, and recovery and adaptation mechanisms	N.A	[56]
	151 indicators were used to evaluate the performance of four modules, including potential hospital risk, structural safety, nonstructural safety, and disaster emergency management, to quantify the disaster resilience of the healthcare system	N.A	[47]
	The hospital function was quantified by the scoring weighted summation results of 38 different component indicators, among which 38 indicators had different weight coefficients	N.A	[57]
Functional measures	Hospital functions are divided into four subfunctions: structured, nonstructured, lifeline, and personnel. Then, the respective functions of different functional levels are fully arranged and combined to form a functional tree. Hospital functions are further quantified according to each combination, to quantify hospital functional resilience	—	[58]
	Define hospital functions based on fault trees, and gradually split hospital functions into multiple functional groups. Hospital resilience was finally determined by judging the functional level of the underlying group and going through a series of conduction paths		[48]
	The integral of the healthcare system function curve quantifies the disaster resilience of the healthcare system. The ratio of the number of healthy people in the disaster event to the healthy population reviewed before the disaster event was used as a quantitative indicator of the postdisaster hospital function of the health care system		[59]
	The disaster resilience of the healthcare system is divided into three types of resilience indicators (RIh^Ph,M) for different services: traffic resilience indicators (RIF^Ph,M), ambulance resilience indicators (RIA^Ph,M), and hospital resilience indicators (RIH^Ph,M)		[60]
	The integral of the healthcare system function curve quantifies the disaster resilience of the healthcare system. The function of individual hospitals is quantified in time by treating the wounded		[61]
	Based on the proportion of injured patients, a segmented functional index was proposed, and this was used as a functional index to calculate hospital disaster resilience		[62]
	A quantitative methodology that computes the capacity of hospitals to operate on injured people in the aftermath of a seismic event is presented. The model incorporates variables such as organizational and human preparedness, damage to buildings, the number of operating theatres, the amount of supplies, and the duration of a surgical treatment		[63]
	The objective function C1 (X) measures waiting time across the city as the average time that a patient would take since the earthquake until completing treatment in the operating room		[64]
	The probability of total functionality of the healthcare system, P (Q), can be expressed as a combination of the probability of quantity, P (QV), and the conditional probability of quality, P (QS | QV), of the offered service		[65]
	Hospital operating capacity (HOC) should be defined as the minimum of all the availability probabilities of the departments on the hospital treatment chains for a certain type of patients, which should be a number not more than 1 (can also be set as percentage)		[66]
