});

var currentUserFhirUrl;
 
FHIR.oauth2.ready(function(fhirClient){
	currentUserFhirUrl = fhirClient.userId;
});

var userIdSections = currentUserFhirUrl.split("/");

$.when(fhirClient.api.read({type: userIdSections[userIdSections.length-2], id: userIdSections[userIdSections.length-1]}))
    .done(function(userResult){

        var user = {name:""};
		if (userResult.data.resourceType === "Patient") {
    		var patientName = userResult.data && userResult.data.name && userResult.data.name[0];
    		user.name = patientName.given.join(" ") + " " + patientName.family.join(" ").trim();
		}
        user.id  = userResult.data.id;
