The Lufkin Daily News reported on Friday that a former employee of the DaVita Lufkin unit was arrested for injecting two DaVita hemodialysis patients with bleach, confirming the tip from my source. RenalWEB has a news summary of events as they have been reported to date (largely by Jessica Savage Lufkin Daily News reporter).
This is not the end of the story. The incidents that police have identified involving bleach are reported to have resulted in hospitalization but not death. On Wednesday DaVita released a statement saying that they believed four deaths were attributable to the arrested nurse; this means at as minimum six patients are involved. It is unclear what evidence DaVita has indicating murder that the Lufkin police does not have, unless murder or manslaughter charges will be forthcoming.
So many questions need to be answered. Where else did Saenz (the arrested nurse) work? How long had she been working as a dialysis nurse? We need a full accounting of her history. I am concerned by a statement in the Wednesday article:
Dr. David Van Wyck, a nephrologist who is vice president of clinical services for DaVita and working with state officials during the investigation of the Lufkin clinic, said on average two to three patients die a month at dialysis centers.
Does he mean "2 or 3 people die during treatment or immediately after treatment and transport to a hospital" or does he mean 'typically in the US, at a 120 patient unit, several patients die each month", the former would not be usual, the later would be all too true - the overall mortality rate among people on dialysis is stuck stubbornly above 20%. What needs to be made clear is how many deaths had there been among Lufkin patients above the typical general mortality rate of 22 to 24%? What were the number of deaths in comparison to the expected? And were the causes what one would expect? For instance an unexpected number of deaths due to hemolysis or extreme dehydration.
