In which category/categories of haemodialysis patients should an increase in treatment time and/or frequency be considered?

	In patients with haemodynamic or cardiovascular instability
	In patients who remain hypertensive despite maximum possible fluid removal
	In patients with impaired phosphate control
	In malnourished patients
	In none of them
	In all of them

Which of the following statement(s) is(are) correct?

	Treatment time is probably an independent factor in patient outcome
	It is very difficult to separate the effect of treatment time and dose of dialysis
	The role of time as an independent determinant factor of dialysis adequacy requires further studies
	None of them
	All of them

Which of the following statement(s) is(are) not correct?

	More frequent haemodialysis sessions have a deleterious effect on vascular access survival
	Increasing dialysis frequency has a favourable effect on blood pressure control
	Increasing dialysis frequency has a favourable effect on nutrition status
	Increasing dialysis frequency has a favourable effect on hospitalization rate and quality of life

How long should a daily haemodiafiltration session be in order to achieve an adequate phosphate removal (specular to dietary phosphate intake)?

Which of the following statement(s) is(are) not correct when dealing with long nocturnal daily haemodialysis?

	Improved phosphate control has been reported in long nocturnal daily haemodialysis with a marked reduction in the dose of phosphate binders
	A marked decrease of intra-dialysis hypotension episodes and cardiovascular complications has been reported in long nocturnal daily haemodialysis with a marked reduction in anti-hypertensive drugs binders
	A marked decrease in oxygen saturation in patients with sleep apnoea syndrome has been reported in long nocturnal daily haemodialysis

Which of the following statement(s) is(are) correct when dealing with more frequent haemodialysis sessions?

	Potential disadvantages of more frequent haemodialysis sessions are related to cost, organization and repeated vascular access punctures
	Daily haemodialysis has an increased cost of disposable material, treatment preparation time and patient transportation
	The cost analysis for daily haemodialysis should include potential cost reductions, such as less consumption of medications, and a reduction in the hospitalization rate
	All of them
	None of them
