However, the study was not so much about the under-diagnosis of depression as it was to discover the rate of post-hospitalization depression and whether it was a risk factor. The researchers were trying to find out if depression, by itself, could cause increased readmissions to the hospital, increased further illnesses, or increased death rates.
The data that was collected included demographic details (race, gender, age, etc.), handicaps, pain levels, forced expiratory volume (breathing) and social network. These are potential risk factors associated in some earlier studies with poorer post-hospitalization survival statistics. It was found that the prevalence of depression in the 311 research participants was 17.4 percent. It was found that depression was the only baseline variable that was associated with reduced survival in the community.
This is very dramatic evidence that mind (brain) often trumps other physical matters in post-hospitalization outcomes. That is why this article is entitled "Depression Kills." Most of us know that depression often kills by leading to suicidal behavior. Now it is clear from this and many other studies that depression kills in other ways by shortening people's lives.
You asked if depression in older adults in the United States is under-diagnosed and, if so, what can be done about it? Professor Ken Wilson, one of the author's of the 2007 UK study has stated "depression is often undiagnosed and both patients and doctors confuse it with other illnesses or general signs of aging." The same is true in the United States. Many studies have confirmed that depression among all populations in the United States is under-diagnosed, but especially in older adults. I don't report this just because I am a psychiatrist. I report this because the studies are clear.
Answering your question "What can be done about it?" will require a much longer discussion than I can offer in this short column. To answer that question, you have to ask, "why is depression under-diagnosed?" Some of the reasons for under-diagnosis are (1) the myth that depression is a normal part of aging (it is not!); (2) the relative lack of mental health care due to "cost-cutting" efforts of hospitals and insurance providers; and, (3) a huge misplaced burden of diagnosis and treatment -- primary care physicians are the sole contact for more than 50% of patients with diagnosable mental conditions and clinical depression is 2 to 3 times more prevalent in primary care patients than in the overall population.
For now, what can be done about doing a better job of diagnosing depression is primarily a consumer burden, since it is not likely that health care systems will change rapidly in the near future to provide better mental health care. Families and friends must be diligent in learning about the symptoms of depression and about getting their loved ones the follow-up and help they need and deserve. In my opinion, over-concern about a life-threatening illness is preferable to under-concern.
