Two recent US verdicts on healthcare workers charged with murdering patients have highlighted the untenable legal situation of their South Africa counterparts.

Medbrief Africa spoke to two of South Africa’s leading experts in the medico-legal and ethical fields about lessons the verdicts may have for local doctors.

Professor Willem Landman, founding CEO of the Ethics Institute of South Africa, and Dr Graham Howarth, Africa chief for the Medical Protection Society agree; local healthcare practitioners fear practicing normal medicine because of the growing tendency to criminalize unintentional error and the lack of legal clarity around the treatment of afflictions leading to death, especially end-of-life choices.

The US cases involve an award-winning ICU physician at Ohio’s Mount Carmel Hospital, Dr William Husel, and an ICU nurse at Tennessee’s Vanderbilt University Medical Center, RaDonda Vaught.

After a lengthy trial which hinged on intent, Husel was this April acquitted of 14 murder charges arising from his administration of dozens of fatal fentanyl overdoses to ICU patients over a protracted period. Vaught on the other hand, was convicted of criminally negligent homicide and gross neglect of an impaired 75-year-old woman suffering a brain bleed. She accidentally administered a paralytic medication, vecuronium, instead of a sedative. On Friday (May 13th), she was sentenced to three years of supervised probation after being struck off the nurses’ roll. As things stand, she will be a convicted felon for the rest of her life. However, the judge granted her a “judicial diversion” (equivalent to an appeal to another court), which could result in her conviction being dismissed – after a successful probationary period.

The case hinged on her use of a computerised device that dispensed a range of drugs. Evidence was that she initially tried to withdraw Versed from a cabinet by typing “VE” into its search function without realising she should have been looking for its generic name, midazolam. When the cabinet did not produce Versed, she triggered an “override” that unlocked a much larger swath of medications, and then searched for “VE” again. This time, the cabinet offered vecuronium.

The criminal cases took between four and five years to complete.

US nurse verdict has ‘chilling effect’

While both illustrate the trend towards criminalising healthcare workers instead of setting up systems and controls to minimise errors and abuses, the Vaught conviction and sentence have had a particularly chilling effect on healthcare workers – and caused outrage among her colleagues in the US.

Says Landman, “While I don’t have all the facts in front of me, my first reaction is that in every human and/or professional practice we admit that there are errors and abuse. It’s par for the course. But if and when that happens, we don’t abandon the practice – rather we set up systems and controls to minimise errors and abuses.”

He said what was striking about the Vaught case was that she was called upon to both dispense and administer drugs – which enlarged the scope for error. Even in regular, commercial pharmacies, double controls applied to dispensing, with juniors checking prescriptions with seniors, Landman said.

“The question then becomes do we approach this in a litigious frame of mind or say errors happen and we deal with it creatively to make sure the error isn’t repeated? We’re all trying to do our best under pressure and faults creep in, as with any system. We should say let us try and creatively do better,” he said.

Howarth said the fear of facing a criminal investigation was widespread among South African healthcare workers – with justifiable reason.

“Sadly, yet again we see a case, (Vaught), where systemic failure seems to have played a significant part in medical error for which an individual healthcare worker is held to account.”

He added; “criminalising unintentional error in a fast moving and complex healthcare environment cannot be right. As well as families losing a loved one through tragic circumstances, a healthcare worker loses their career and liberty.”

Howarth said the fear of criminal charges created a culture of blame and fear which impeded learning from mistakes.

“Indeed, the Vaught case presents a significant opportunity for quality and safety improvements in electronic prescribing and dispensing systems and processes, so they are failsafe, and errors are avoided in the future, protecting both patients and healthcare workers,” Howarth added.

SA doctors live in constant fear – MPS

He said that in South Africa, “90% of doctors tell us that the prospect of facing a criminal investigation impacts their mental health, and nearly one in two doctors have considered leaving the profession due to this culture of fear. At MPS we’ve urged the South African government to initiate a review into culpable homicide law and its application in a healthcare setting. The importance of achieving a long-term solution for healthcare workers and patients alike, cannot be overstated.”

Landman said that criminalising unintentional error and talking of homicide was “heavy stuff. We know that healthcare workers do fear litigation and criminal and civil liability – more and more so in our environment.”

Turning to the US doctor’s trial, he said that while unable to pronounce on the medical facts, the elevated dosages, seemingly without a stepped approach was conspicuous.

Other salient factors would be the drug tolerances of individual patients, what other drugs they may have been on which impacted on the elevation of the dose, and the perennially vexed question of pain perception.

“If a patient pleads for pain alleviation, a doctor has to make some kind of subjective judgment on how they subjectively experience pain. Suffering is induced either by distress or pain, or both. It can be mental or physical, and for various reasons. Doctors have to judge. I’m always very suspicious of the law putting its big foot in, especially in an area where all you want is good practice. Doctors don’t enter and practice medicine to kill patients. Were there any guidelines on pain management involved here? It’s not always clear with particular drugs and underlying conditions. Moral or legal judgements lean heavily on and can only be as good as the facts.”

“Double effect’ of pain relief

He said that with the Husel case there were some major factors involved that needed elaboration. The concept of ‘double effect,’ meant that alleviating pain could shorten a life – or that the doctor intentionally killed a patient (as in euthanasia).

“How do you distinguish? Our Supreme Court says that to kill in order to stop pain is murder, but if the inevitable result is death, you’re not criminally liable.”

“It depends on the mind of the doctor. Yes, there is causality; an act that led to death, but what is the doctor’s mindset?” Landman stressed.

He said the most prominent current South African euthanasia court application was that of Dieter Harck who suffers from advanced motor neurone disease. Harck is asking to be allowed to be legally assisted with dying when the appropriate time arrives.

“The Supreme Court of appeal (SCA), has said that when an appropriate case comes before our courts the common law will no doubt evolve to conform to our imbedded Constitutional rights which cover compromised autonomy, dignity and bodily integrity,” Landman said.

However this had yet to happen due to various interruptions and delays in Harck’s application, including the death of the presiding judge. The case is due to resume on May 31st.

Landman said the courts would not interfere with the law-making role of parliament and would probably suspend judgment and tell MPs to rectify the current inappropriate common law to bring it into line with the Constitution.

Unfortunately, there was no effective alternative to putting assisted dying on the agenda of SA’s elected representatives other than via the courts. Civil society had ‘negligible powers of persuasion.”

Landman said this made the prospects dim, citing Professor Pieter Carstens, a constitutional law expert, who has bluntly said that our constitutional right to assisted dying faced “the hypocrisy and lack of courage to act by lawmakers and government.”

Landman’s authoritative contributions to the much-needed proposed legal amendments have been ignored by parliament.
