[Evaluation and socio-economic relevance of an integrated osteoporosis health care network]. / Evaluation und sozio-ökonomische Bewertung eines Modells zur Integrierten Versorgung zur Behandlung der Osteoporose.

During the last 6 to 7 years, integrated health care has become more and more important in Germany. In August 2005 we initiated a collaborative project involving two orthopaedic clinics in Hanover and one rehabilitation clinic in Bad Pyrmont specialising in the treatment of osteoporosis. Here, we report the results of 633 women (83 ± 7 years) and 162 men (75 ± 10 years) who participated in this programme between August 2005 and August 2012. All participants gave informed consent. All patients were supplemented with 1200 mg of calcium and 800 IU of vitamin D. Intravenous bisphosphonates were given to 91% and parathyroid hormone to 7% of the patients. Two per cent received miscellanous therapeutic agents. Follow-up visits were attended by 89% of the patients after one year and 78% after two years. During this time, a significant improvement was observed in vitamin D, parathyroid hormone and the bone marker desoxypyridinoline. DXA measurements were falsified by degenerative disease or fractures. In the men, however, a significant increase was observed in the total hip. Over the two-year period, 16 vertebral and 3 non-vertebral fractures occurred in the women. In the men, one non-vertebral and 5 vertebral fractures were noted. Among the women, 18 died and 6 were admitted to a nursing home. The corresponding figures among the men were 7 and 4, respectively. According to the figures provided by the central German institute for statistics, the death rates among the women were significantly lower than expected, whereas a tendency toward lower death rates was seen in the men. In addition, the number of new hip fractures in the women was lower than the epidemiological data suggest. This was also noted in the men. Even among the very old, a musculoskeletal rehabilitation programme combined with adequate pharmaceutical therapy may prove very successful when it comes to death rates and nursing home admissions. The latter in particular may be very expensive in the long run and our longitudinal follow-up study may demonstrate cost-effectiveness if the rehabilitation programme is commenced as early as possible.

[Therapy of osteoporosis from the viewpoint of evidence-based medicine]. / Die Therapie der Osteoporose aus dem Blickwinkel einer auf Evidenz basierenden Medizin.

DEFINITION AND SOCIOECONOMIC ASPECTS: Osteoporosis is a disease characterized by low bone mass and an increased susceptibility to fractures. It represents an enormous burden for the social security systems in developed countries. In Germany, approximately two million women and 800,000 men suffer from vertebral fractures and estimates for hip fracture incidence are in the range of 70,000-130,000 per year. The resulting costs for hip fractures alone could be calculated to 3-5 billion German marks. THERAPY ACCORDING TO EVIDENCE-BASED MEDICINE (EBM): According to Sackett et al. 1996, evidence-based medicine is the conscientious, explicit, and judicious use of current best evidence in making decisions about the care of individual patients. The practice of evidence-based medicine means integrating individual clinical expertise with the best available external evidence from systematic research. OSTEOPOROSIS THERAPY: The goal of osteoporosis therapy is to prevent fractures and several therapeutic options are available for this disease. With respect to proven fracture benefit, however, the quality of evidence from randomized clinical trials varies substantially among therapies. From systematic research the best external evidence is available for a supplementation with calcium and vitamin D and a therapy with the bisphosphonates alendronate or risedronate, as well as the SERM raloxifene. For other therapeutic agents like fluorides, vitamin D metabolites, calcitonin, and etidronate the quality of evidence is much lower. So far, there is no evidence for other pharmaceutical therapies. Hip protectors are effective for the prevention of hip fractures.
