PMID 30517579WHAT IT FOUND
Hemodialysis patients who received video education and follow-up conversations during dialysis were 3.54 times more likely to reach target interdialytic weight loss than controls.
Key findings
01Intervention group patients were 3.54 times more likely to reach the goal than control group patients.
02The intervention group showed lower variability and higher ideal percentage of weight loss than the control group, except at the first measurement.
03Patients who participated in the educational and motivational intervention decreased the pattern of weight gain in interdialytic periods.

What it does not show
Patients were not randomly assigned; they were split by dialysis day, so differences could come from group characteristics or contact between patients on different days. The study was done in one dialysis unit, so it does not show the result in other services or populations. The authors state that the non-randomization was chosen because fixed dialysis schedules and patient interaction could bias outcome evaluation. The authors note that the cost of making the educational video may limit reproducing the intervention in some health services.
The easy way to misread this
Do not assume the video alone caused the weight control improvement. The intervention also included repeated dialogues and reinforcements, and the groups were not randomly assigned.
