Hand hygiene saves lives

It should be easy - the fact pattern is straightforward enough

Health care workers fail to wash their hands, and health care-associated infections contribute to 10,000 of the 24,000 annual iatrogenic deaths of Canadians

So why is plaintiff success in this area of medical malpractice litigation so elusive? At one operation an elderly woman had a heart valve replaced, another repaired, and a blocked coronary artery bypassed. The operation was a resounding success - but she died of a postoperative infection that was contracted in a prestigious teaching hospital

Vince Lombardi attributed his legendary success as a football coach to practising the basics. The medical profession develops more dazzling footwork every year, but gets tripped up on the basics: interpersonal communication, showing compassion, basic history and examination - and hand hygiene

More than 150 years ago, Hungarian obstetrician Ignaz Philipp Semmelweis reduced maternal mortality from 18% to 3% by requiring his own team of doctors and students to disinfect their hands with chlorinated lime after performing autopsies and before examining labouring women

Hand-washing was not enough

His colleagues’ disbelief and denial - coupled with his lack of diplomacy in dubbing them “murderers” - caused him to be dismissed from his position as head of the prestigious Women’s Hospital in Vienna, Austria

Disbelief and denial...are still alive and well today in Canadian hospitals

In studies of adherence to protocols for hand-washing between patients, compliance rarely exceeds 40%. Casual observation on almost any ward in any Canadian hospital will confirm these research findings. Infections acquired in hospital affect nearly 10% of patients and cost tens of millions of dollars annually

The mini-epidemics that capture public attention - SARS, necrotising fasciitis and Methicillin Resistant Staphylococcus Aureus - are merely drops in a steady stream of preventable cross-infection

The problem is systemic, epidemic and endemic. In a systemic sense, every time an individual caregiver fails to disinfect his/her hands, that single lapse contributes to death and disablement of patients

Medical malpractice litigation, by contrast, is focused on finding one caregiver, or a small number, whose individual act(s) of negligence probably caused a single adverse outcome

Because the delivery of health care is so complex, traditional medical malpractice litigation strategy can rarely succeed in this area. There are occasional exceptions, as when two patients develop necrotising fasciitis and have only simultaneous hospitalization in common

But The Lawyers Weekly is a newspaper not a historical journal

So what’s new? Relatively new (2002) are the U.S. Centers for Disease Control and Prevention completely revised guidelines for hand hygiene in health care settings. Soap and water is for the 10% of the time that hands become visibly soiled; most germs are not killed

90% of the time the prescribed standard routine between handling of patients is a 15-30 second alcohol-based hand rub. The alcohol evaporates and toweling is not required. (Rum on the naval surgeon’s amputation stump?) Echoing what Semmelweis showed more than 150 years ago, washing with soap and water is not enough. Alcohol hand rub removes - actually kills - live bacteria and viruses more effectively than water and any soap, regular or antibacterial. Compliance with the new guidelines has been shown to materially reduce hospital infection rates

In intensive care units, where a health care worker can need up to 40 hand-hygiene procedures per hour in moving between patients, alcohol hand rub for 15-30 seconds while walking from bed to bed is far more practicable than hand-washing with soap and water for 1-2 minutes at a sink. Glycerol in the alcohol rub is also much kinder to the hands than soap

Correct use of disposable surgical gloves is supplemental, does not prevent cross-infection and is not a substitute for correct hand hygiene. Incorrect use of surgical gloves is common and compounds the problem

Not all postoperative infections are caused by cross-infection

Antibiotic-resistance patterns generally distinguish hospital-acquired infections from those that are caused by germs that are normally present on healthy skin or mucous membranes

In most instances, circumstantial evidence is insufficient to identify an individual caregiver who has probably transmitted a germ between patients, so traditional medical malpractice litigation is thwarted

A systemic approach to medical and nursing negligence is largely uncharted territory. In cases of nosocomial (hospital-acquired) infection, an argument might go thus: 1. the plaintiff is one of the 9% of the patients who acquire infection at this hospital; 2. other patient and family witnesses have testified that only one in four caregivers comply with hand-hygiene guidelines; 3. research shows that compliance cuts hospital-acquired infections by four-fifths; and 4. on a balance of probability, therefore, this patient would not have suffered a hospital-acquired infection if the team of caregivers had complied with guidelines

The courts and defence organizations will doubtless take some time to adjust to this approach, but if enough litigators persistently pursue it, defence counsel and judges will need to sit up and take notice

Analogous with the current ‘Sunnyside Hospital prostate biopsy suit’, a class action on behalf of patients who have acquired cross-infection at a particular hospital could develop similar arguments

Failed hand hygiene is a mundane and frequent factor in iatrogenic injury and death. Personal injury litigators can by an unorthodox approach both help their clients recover damages and raise the consciousness of the public and the medical and nursing professions
