Rising Mortality Rates for People with Serious Mental Illness

Fig 1 (Hoang et al., 2011). Trend in standardised 365 day all cause mortality ratio for all people discharged from hospital with principal diagnosis of bipolar disorder or schizophrenia.


The "mortality gap" is the differential between the mortality rates for the general population and for persons with serious mental illness (schizophrenia and bipolar disorder). A new study from England examined hospital records for psychiatric patients discharged between 1999 and 2006, and determined how many had died within one year (Hoang et al., 2011). The authors expected to see a drop in the mortality gap over time due to government programs:
Over the past decade several strategies have been implemented in England and Wales aimed at reducing the mortality gap between people with serious mental illness and the general population, including those to address deliberate self harm and to reduce suicide (7 8 9), to decrease smoking (10 11 12), alcoholism, and drug misuse (13 14) and to deal with other lifestyles associated with increased mortality (15 16). Recent studies have suggested that the rate of suicide has been stabilising among people with mental disorders as a whole (17 18 19 20 21); however, trends in mortality for people with schizophrenia or bipolar disorder remain poorly characterised, particularly the relative contributions of natural and unnatural causes. The United Kingdom government’s recent mental health strategy states that “more people with mental health problems will have good physical health” as one of its objectives, specifically stating that “fewer people with mental health problems will die prematurely” (22). It is therefore timely to review the level of and trends in these recognised inequalities.
However, as illustrated in Fig. 1 above, the opposite trend was observed, with increased mortality for those with schizophrenia and bipolar disorder. The standardized mortality ratios show a rise from ~30-60% greater than the general population to about double the population average:
For people discharged with schizophrenia, the ratio was 1.6 in 1999 and 2.2 in 2006 (P<0.001 for trend). For bipolar disorder, the ratios were 1.3 in 1999 and 1.9 in 2006 (P=0.06 for trend). Ratios were higher for unnatural than for natural causes. About three quarters of all deaths, however, were certified as natural, and increases in ratios for natural causes, especially circulatory disease and respiratory diseases, were the main components of the increase in all cause mortality.
These results are alarming (but not new, unfortunately) and similar to those reported by Chang et al. (2011) - see Improving the Physical Health of People With Serious Mental Illness. In that post, I mentioned the possible role of "second generation" or atypical antipsychotics, which can cause substantial weight gain and hence diabetes, hypertension, cardiovascular problems, high cholesterol, and stroke. To counteract these serious side effects, a regular part of mental health treatment should include programs that promote better physical health: smoking cessation and nutritionists and structured exercise classes in addition to standard psychiatric care and substance abuse treatment. For example, a six month intervention pilot study enrolled 63 overweight participants at psychiatric rehabilitation day programs and showed promising initial results (Daumit et al., 2010).

These concerns were mentioned earlier in a systematic review of the literature by Saha et al. (2007), who urged immediate action:
“in light of the potential for second-generation antipsychotic medications to further adversely influence mortality rates . . . optimizing the general health of people with schizophrenia warrants urgent attention.”

October 10 was World Mental Health Day, an event designed to raise public awareness of mental health issues:
This year the theme is "Investing in mental health". Financial and human resources allocated for mental health are inadequate especially in low resource countries. The majority of low- and middle-income countries spend less than 2% of their health budget on mental health.

Many countries have less than one mental health specialist per one million population. Even a considerable part of the limited resources is spent on large mental hospitals and not for services delivered through community and primary health care.

We need to increase investment for mental health and to shift the available resources towards more effective and more humanitarian forms of services.

Excellent article and blog.

Wow. Excellent article. So strange how there is a rise in the maternal mortality rate in the past 40 years and also there is this rise as well. Pretty sobering and disconcerting, with all of our medical gains...look at this.

It is sad that in this day and age we cannot find ways of helping people with serious mental illness. Although it is apparent that there are many people working on the problems and I am sure that eventually the rates will improve.

I covered this study on my blog about a month ago here, and one possible explanation of the data is that, as mental health services are decreased, those that are actually admit (and therefore discharged) are, on average, worse off, so the mortality rates are increasing.

However, at this point, there's really no way to know. I think your hypothesis that the weight gain associated with atypical antipsychotics may be a culprit is plausible. What we need is one that correlates specific illnesses and levels of severity with mortality rates.

Does anyone have stats for what happened for the same time in Canada? Is it the drugs or the lack of health care for people with problems with employment?

And when you wrote "atypical", I instantly thought of this: http://thelastpsychiatrist.com/2011/10/the_rise_and_fall_of_atypical.html

This is a really well written article. It's crazy to think that the mortality rate has been raising, and it's sad to think that these mental illnesses are still not widely understood and supported by the general public.

I have read many such articles and notice that the lack of physical health care on MH wards in the UK is never mentioned. Patients do not receive essential medications for hypertension and cardiac problems. Very abnormal ECGs and blood tests are not reported to the GP in discharge summaries. The only way a GP becomes aware of these problems is if the patient obtains copies of his/her psych records.

Patients' physical problems are also ignored if they attend A&E Departments as doctors refuse to see beyond the MH label.

Bluntly stated, scrap all mental health programs before you start talking mental health. False data has already led us to these abysmal numbers. Trade those cul-de-sacs for Truth.

Look at Scientology, i.e. experts on the mind, who have workable solutions anyone can apply. Clear-up any "misunderstoods" and you'll be fine.

Go to www.scientology.org/fundamentals-of-thought/videos.html click "Online Courses," dealing with 18 'life' problems/solutions. Each is free and short, 1-2 days, but will last a lifetime. Look, don't listen. Something can be done about it!...Semper Fi

giljones - Bluntly stated, Scientologists are absolutely NOT experts on the mind. Instead of wasting time on those crappy "Online Courses", fans of this blog might want to read about how $cientology "expertise" on psychiatric care caused the death of Lisa McPherson.

This report in The Village Voice is also informative.
