When doctors go on strike, patients stop dying

By Dr Raj Persaud, Consultant Psychiatrist, and Dr Peter Bruggen, retired Consultant Psychiatrist

As doctors vote on whether to strike in the UK, what’s the likely impact of withdrawing medical care on the health of the nation? The doctor’s union, the British Medical Association, seems to be throwing its chips on a gamble that the government doesn’t want to alarm the electorate.

But when doctors strike, the scientific evidence finds that patients stop dying.

The most comprehensive review of the medical impact of doctors’ strikes is published in the prestigious academic journal Social Science and Medicine. A team, led by Solveig Cunningham and Salim Yusuf at Emory and Georgetown Universities in the US and McMaster University in Canada, analysed five physician strikes around the world, all between 1976 and 2003.¹

In the different strikes analysed, doctors withdrew their labour for between 9 days and 17 weeks. Yet all the different studies report population mortality either stays the same, or even decreases, during medical strikes. Not a single study found death rates increased during the weeks of the strikes, compared to other times.

For example, in a strike in Los Angeles County, California, in January 1976, doctors went on strike in protest over soaring medical malpractice insurance premiums. For 5 weeks, approximately 50% of doctors in the county reduced their practice and withheld care for anything but emergencies. One analysis, quoted by Cunningham and colleagues, found that the strike may have actually prevented more deaths than it caused.

It’s the fact that elective, or non-emergency surgery, tends to stop during a doctors’ strike, which seems to be the key factor. It looks like a surprising amount of mortality occurs following this kind of procedure which disappears when elective surgery ceases due to doctors withdrawing their labour. Mortality declined steadily from week 1 (21 deaths/100,000 population) to week 6 (13) and 7 (14), when mortality rates were lower than the averages of the previous 5 years. However, as soon as elective surgery resumed, there was a rise in deaths. There were 90 more deaths associated with surgery in the 2 weeks following the strike in 1976 (ie when doctors went back to work) than there had been during the same period in 1975.

But, unlike Los Angeles, what about the impact of doctors’ industrial action where the majority of doctors participate, and the strike lasts several months?

Cunningham and colleagues report on a strike in Jerusalem from 2 March to 26 June 1983 due to a salary dispute between the government and the Israel Medical Association. 8,000 of Jerusalem’s 11,000 physicians refused to treat patients inside hospitals, though many of them set up separate aid stations where they treated emergency cases for a fee.

One analysis examined death certificates from several months surrounding the strike period, 16 February-3 September 1983, and from a control period the previous year, 17 February-3 September 1982. Mortality did not increase during or after the strike, even when elective surgery resumed. The pre-strike deaths for the control period and the strike period were identical at 89; there were six fewer deaths during the strike than during the control period, while in the 10 weeks following the strike, there were seven more deaths than there had been in 1982.

In an intriguing example of how a doctors’ strike can backfire, the authors of this particular mortality analysis argue that this apparent lack of impact of the strike on mortality suggests that there was an over-supply of doctors in Jerusalem at the time. The problem with drawing conclusions remains that the strike did not involve the whole scale deprivation of medical services. Cunningham and colleagues point out in their review paper that striking physicians opened aid stations, supplementing medical care and preventing people from mobbing the hospitals. While physicians were technically on strike during the 4 months of the dispute, most did not in fact adhere to the industrial action regulations. In truth, most doctors in Jerusalem provided care in a private or partially private context, so, while participating in spirit, they did not actually withdraw services.

Another intriguing study analysed changes in mortality by studying the Jerusalem Post’s newspaper reports of funerals during another Jerusalem doctors’ strike, this time between March and June of 2000. This one arose from the Israel Medical Association’s conflict with the government’s proposed wages. The hospitals in the area cancelled all elective admissions and surgeries, but kept emergency rooms and other vital departments, such as dialysis units and oncology departments, open.

The funeral study found a decline in the number of funerals during the 3 months of the strike, compared with the same months of the previous 3 years. One burial society reported 93 funerals during one month of the strike (May 2000) compared with 153 in May 1999, 133 in May of 1998, and 139 in May 1997.

Cunningham and colleagues summarise their review of research assessing the effects of doctors’ strikes on mortality, finding that four of the seven studies report mortality dropped as a result of medical industrial action, and three observedno significant change in mortality during the strike or in the period following.

There are several possible interpretations for this surprising finding. One is that as its elective or non-emergency surgery which is usually most effected in a doctors’ strike, it could be that the mortality findings reflect an impact of elective surgery. The findings could be important because they could illuminate the relatively high risks of elective surgeries, which may actually increase mortality. This might be a finding that would not have been highlighted if it wasn’t for doctors’ strikes.

Another sobering possible conclusion is that the public, and perhaps doctors themselves, overestimate the ability of medicine to stave off or have an impact on mortality.

The problem with interpreting the data, as Cunningham and colleagues point out in their review, in all medical strikes studied so far, not all doctors down tools. In the 1976 Los Angeles strike only 50% of physicians were involved. So doctors’ strikes don’t necessarily drastically reduce access to healthcare. Given the purpose of most strikes is to deprive management of the worker’s labour, and its benefits, this raises the question of how effective a doctors’ strike can ever be in comparison to other occupations. The very difficulty in getting physicians to withdraw their labour in the way other occupations can do hints at a fundamental difference between what it is to be a doctor compared to pursuing other ways of making a living. A doctor, the research on strikes illuminates, isn’t something you do, it’s something you are. This issue of identity is why it’s so much more difficult for doctors to simply discontinue practising medicine. It’s a character flaw prone to exploitation by governments and employers, effectively frustrating standard union tactics.

Another theory as to why patients live longer when doctors go on strike is that the profession finally shakes off the shackles of its employer’s restrictive practices, and returns, albeit temporarily, to practising medicine freely, as it would really like to. And perhaps, British Medical Association take note, that’s actually the most effective sort of industrial action doctors can ever take.
