Summary List of Empirical Evidence in Teleradiology: Outcomes

REFERENCE	YEAR	COUNTRY	STUDY DESIGN	SAMPLE SIZE	MODALITY/INVERVENTION	FINDINGS	COMMENTS
Ichikawa et al.141	2005	Japan	Observational	Nonempirical	Grid portal	Grid aggregates computational capabilities for brain science	Portal enabled flexibility with large computational power
Zulu et al.142	2007	South Africa	Observational	316	Teleconsult/head injury	Reduced unnecessary travel; 84% treated locally; 16% required transfer	Telemedicine allows access to external resources and ensures optimal use of resources
Fabbri et al.143	2008	Italy	Observational	12,675	Telemedicine/head injury	Predicted unfavorable outcome: sensitivity 95.6%; specificity 86.0%	The scoring system for organ dysfunction is good predictor
