Comorbidity of low back pain: Representative outcomes of a national health study in the Federal Republic of Germany.


This new paper by S Schneider and colleagues from Heidelberg in Germany takes a look into low back pain. It is published in the european journal of pain.
BACKGROUND: Unlike other biopsychosocial risk factors, the role of comorbidity in low back pain is largely unknown.
AIMS: The purpose is (1) to generate prevalence data on back pain in the total adult population and (2) to identify the most common physical comorbidities in subjects with back pain. This paper also (3) analyses the gender-specific and age-specific comorbidity structure.
METHODS: The National German Health Survey is the first study to provide the basis for a representative nationwide analysis of back pain prevalence and the associated comorbidities. The net sample comprises a total of 7124 Germans aged 18-79.
RESULTS: One in three Germans (34%) experienced back pain during the seven days prior to being interviewed. The one-year prevalence rate is 59%. All the morbidities investigated by us are more common in subjects with back pain than in individuals without back pain. The most common comorbidities associated with back pain are musculoskeletal disorders like rheumatoid arthritis, osteoarthritis and osteoporosis, followed by cardiovascular and cerebrovascular disease.
CONCLUSIONS: The present study investigating 31 physical diseases is the most extensive analysis to date on the topic of back pain and comorbidity. This is an attempt to cast light on the tangled relationships involved in developing and coping with back pain. In view of the large percentage of unspecific back pain, we believe it is important for physicians treating back pain to extend their history and diagnostic analysis skills to embrace comorbidities related to the back pain.

Measuring patient quality of life: is the health utility index useful?

This article by R Tempier and colleagues from Saskatchewan university in Canada takes a look at the relationships between psychotic disorders and chronic conditions susch as arthritis. 

The purpose of this paper is to report Health Utility Index Mark 3 (HUI3) scores, at baseline and at one year, for patients with psychotic disorders. Eighty two randomly selected outpatients from a Montreal teaching hospital completed the HUI3 and other measures of symptoms and side-effects. At baseline, the average Global Utility score was 0.64, which is rated in the “dysfunctional” health status range. Improvements were seen at one year follow-up in the Global, Dexterity, Cognition, and Pain Utility scores. The proportion of individuals rated in the “healthy” health status range improved by 32% from baseline to one year. HUI3 scores were negatively related to measures of psychotic symptoms and side-effects. We propose that the HUI3 should be used to assess health-related quality of life (HRQOL) in patients with psychotic disorders. Scores could be compared with other populations affected with chronic conditions (e.g., Alzheimer dementia, cancer, arthritis, etc.).
