[Assessment of osteosynthesis in X-ray images]

Osteosynthesis refers to various surgical procedures, closed or open, for the treatment of fractures of any age. To document and control the osteosynthesis and the healing process X‑ray controls of the affected skeletal segment are performed during the operation and at regular intervals. To assess the quality of an osteosynthesis or to identify a complication, a comprehensive and systematic image review is useful. This includes the assessment of the restoration of the functional anatomy, the position of the material in relation to the surrounding structures, an evaluation of the stability as far as this is possible, and a control of the bone healing in a functionally correct position.

Bond-specific fragmentation of oligopeptides via electronic stopping of swift heavy ions in molecular films

Highly bond-specific fragmentation of oligopeptides induced by swift heavy ion (SHI) irradiation was investigated by means of mass spectrometry. In pronounced contrast to measurements of samples irradiated with keV ions, oligopeptides which were exposed to 946 MeV Au ions show a high abundance of specific fragments. The highly bond-specific nature of SHI-induced fragmentation is attributed to electronic stopping as the most relevant energy loss mechanism for SHI in the oligopeptide samples in combination with the subsequent coupling between the excited electronic and the atomic subsystem. Fragmentation induced by SHI is observed to be further influenced by the structure of the oligopeptides, suggesting that electronic excitation and/or the electronic-vibrational coupling depend on the details of the molecular structure.

[Assessment of patellar dislocations in childhood and adolescence : Accident-related or predisposition-related?]

BACKGROUND

Numerous predisposing factors are known for patellar dislocations but the extent to which these or the trauma cause the dislocation is often unclear.

AIM

This study investigated whether the analysis of the accident mechanism and anatomical predisposition in juvenile patellar dislocations enables a conclusion as to the causality.

MATERIAL AND METHODS

Retrospective cohort study, evidence level III. In-house employers' liability insurance association (BG) cases with the diagnosis of patella dislocation in patients under 18 years were descriptively evaluated with respect to demographic and predisposing aspects as well as regarding accident information. The accident mechanisms were sorted into subgroups: direct impact, trivial trauma, fall, torsional trauma.

RESULTS

A total of 54 patellar dislocations were identified with a patient age of 14 years (range 9-18 years). A mild valgus configuration was found in 39% of the cases, on average normal torsion, a tibial tuberosity-trochlea groove (TTTG) distance of 17 mm (range 8-24mm), with 41% a high proportion of patella alta and a trochlear deformity in 57%. Only 20% of the children had no relevant predispositions. The trivial traumas showed the highest proportion of recurrent dislocations with 50% and in the other accident categories the proportion of first dislocations was >75%. In the fall cohort the rate of children without relevant predisposition was highest.

CONCLUSION

The predisposition rate in infantile patellar dislocations is high; however, falls are always significant accident events as well as medial direct impact. Torsional trauma is also a significant causative factor, unless high-grade trochlear dysplasia is present, whereas trivial traumas are not.

Coulomb blocking of sequential tunnel ionization in complex systems

When atoms and molecules are exposed to intense low frequency laser fields, the dominant response is sequential tunnel ionization of charge states with increasing ionization potential. Sequential ionization is assumed to proceed as separate one electron processes. The theoretical analysis developed here reveals that in complex systems sequential tunnel ionization can be inhibited by Coulomb blocking. When ionization potentials of subsequent charge states are close to each other, multiple tunneling events can occur during a half cycle and in close proximity, so that a tunneled electron can block the next tunneling electron. In sub-nm clusters driven by near infrared single-cycle pulses, Coulomb blocking reduces two-electron sequential tunneling by up to 2-3 orders of magnitude.

The Spirodela polyrhiza genome reveals insights into its neotenous reduction fast growth and aquatic lifestyle

The subfamily of the Lemnoideae belongs to a different order than other monocotyledonous species that have been sequenced and comprises aquatic plants that grow rapidly on the water surface. Here we select Spirodela polyrhiza for whole-genome sequencing. We show that Spirodela has a genome with no signs of recent retrotranspositions but signatures of two ancient whole-genome duplications, possibly 95 million years ago (mya), older than those in Arabidopsis and rice. Its genome has only 19,623 predicted protein-coding genes, which is 28% less than the dicotyledonous Arabidopsis thaliana and 50% less than monocotyledonous rice. We propose that at least in part, the neotenous reduction of these aquatic plants is based on readjusted copy numbers of promoters and repressors of the juvenile-to-adult transition. The Spirodela genome, along with its unique biology and physiology, will stimulate new insights into environmental adaptation, ecology, evolution and plant development, and will be instrumental for future bioenergy applications.

Spirodela, or duckweed, is a basal monocotyledonous plant with both pharmaceutical and commercial value. Here, the authors sequence the genome of Spirodela polyrhiza, suggesting its genome has evolved by neotenous reduction and clonal propagation, and provide a platform for future comparative genomic studies in angiosperms.

[Detection of a Disease Cluster by the Health Authorities of Stendal District due to Campylobacter jejuni in a Nursery After the Consumption of Raw Milk]

A notification from a laboratory concerning the detection of Campylobacter jejuni in a 6-year-old boy initiated the investigation carried out by the health authorities from Stendal district, in order to explain the morbidity rate caused by the germ. The day after the boy's pediatrician informed about a visit to a farm, which was confirmed by the head of the nursery. She told the health authorities about the consumption of raw milk during their visit at the farm.The following days more children fell sick. Within 10 days the total number of diseased children was 21. The health authorities asked for stool samples of the diseased children, nursery nurses and the head of the farm since raw milk presents a potential cause of infection. The health authorities together with the Saxony-Anhalt State Office for Consumer Protection conducted a retrospective cohort study. The aim was to explain the association between the exposure from raw milk consumption and the occurrence of the disease from C. jejuni. Based on a questionnaire data about the food and milk intake at the nursery and at home and about the trip to the farm were collected. 91% of the children's cohort and 86% of the adults' cohort were captured.The exposed group at risk showed a higher risk of falling ill than the group, which was not exposed. The risk factor raw milk explained the difference. Furthermore, the analysis of milk samples taken by the district veterinary office from 2 cows and from the farm's tank was able to detect the germs. The correlation of the illness, the consumption of raw milk, the detection of C. jejuni in the samples taken from the children and the samples taken from the cows was evident. Based on the case the health authorities recommended that heads of nurseries as well as heads of dairy farming in the district of Stendal needed to be advised on raw milk. Nurseries are still allowed to take trips to farms. However, raw animal derivates including milk must not be consumed.

Chromatin organisation in duckweed interphase nuclei in relation to the nuclear DNA content

The accessibility of DNA during fundamental processes, such as transcription, replication and DNA repair, is tightly modulated through a dynamic chromatin structure. Differences in large-scale chromatin structure at the microscopic level can be observed as euchromatic and heterochromatic domains in interphase nuclei. Here, key epigenetic marks, including histone H3 methylation and 5-methylcytosine (5-mC) as a DNA modification, were studied cytologically to describe the chromatin organisation of representative species of the five duckweed genera in the context of their nuclear DNA content, which ranged from 158 to 1881 Mbp. All studied duckweeds, including Spirodela polyrhiza with a genome size and repeat proportion similar to that of Arabidopsis thaliana, showed dispersed distribution of heterochromatin signatures (5mC, H3K9me2 and H3K27me1). This immunolabelling pattern resembles that of early developmental stages of Arabidopsis nuclei, with less pronounced heterochromatin chromocenters and heterochromatic marks weakly dispersed throughout the nucleus.

No evidence of pathogenic involvement of cathelicidins in patient cohorts and mouse models of lupus and arthritis

Apart from their role in the immune defence against pathogens evidence of a role of antimicrobial peptides (AMPs) in autoimmune diseases has accumulated in the past years. The aim of this project was to examine the functional impact of the human cathelicidin LL-37 and the mouse cathelicidin-related AMP (CRAMP) on the pathogenesis of lupus and arthritis. Serum LL-37 and anti-LL-37 levels were measured by ELISA in healthy donors and patients with Systemic Lupus Erythematosus (SLE) and Rheumatoid arthritis (RA). Pristane-induced lupus was induced in female wild type (WT) and cathelicidin-deficient (CRAMP-/-) mice. Serum levels of anti-Sm/RNP, anti-dsDNA, and anti-histone were determined via ELISA, cytokines in sera and peritoneal lavages were measured via Multiplex. Expression of Interferon I stimulated genes (ISG) was determined by real-time PCR. Collagen-induced arthritis (CIA) was induced in male WT and CRAMP-/- mice and arthritis severity was visually scored and analysed histomorphometrically by OsteoMeasure software. Serum levels of anti-LL-37 were higher in SLE-patients compared to healthy donors or patients with RA. However, no correlation to markers of disease activity or organ involvement was observed. No significant differences of autoantibody or cytokine/chemokine levels, or of expression of ISGs were observed between WT and CRAMP-/- mice after pristane-injection. Furthermore, lung and kidney pathology did not differ in the absence of CRAMP. Incidence and severity of CIA and histological parameters (inflammation, cartilage degradation, and bone erosion) were not different in WT and CRAMP-/- mice. Although cathelicidins are upregulated in mouse models of lupus and arthritis, cathelicidin-deficiency did not persistently affect the diseases. Also in patients with SLE, autoantibodies against cathelicidins did not correlate with disease manifestation. Reactivity against cathelicidins in lupus and arthritis could thus be an epiphenomenon caused by extensive overexpression in blood and affected tissues. In addition, other cationic AMPs could functionally compensate for the deficiency of cathelicidins.

Costs of Diabetes Mellitus (CoDiM) in Germany, direct per-capita costs of managing hyperglycaemia and diabetes complications in 2010 compared to 2001

INTRODUCTION

To identify direct health care costs of patients with diabetes in Germany in 2010, with focus on costs of treating hyperglycaemia and costs caused by diabetes complications, and to compare findings with results from the CoDiM study 2001.

MATERIAL AND METHODS

The cost analysis was based on administrative data (18.75% random sample of 1.5 million insured persons). Medical costs covered by statutory health insurance and costs covered by nursing care insurance were included. Incremental differences in costs of patients with diabetes (n=30 987) and age and sex-matched subjects without a diagnosis of diabetes (controls) were estimated according to the number and type of complications. Costs were standardised to the German population.

RESULTS

In 2010, incremental medical costs attributed to diabetes were € 2 391 (95% confidence interval: 2 257-2 524) per patient with diabetes. Of that amount, 26.5% were spent for the management of hyperglycaemia (€ 633 (622-644)) and 73.5% for the treatment of comp-lications (€ 1 758 (1 627-1 889)). Nursing care contributed incremental costs of € 289 (249-330), of which 98.8% was due to complications. From 2001 to 2010 the incremental per-capita costs for medical and nursing care decreased by 4.8% (controls: +3.9%), the per-capita costs for treating hyperglycaemia increased by 2.0% and the per-capita costs for complications decreased by 7.0%.

CONCLUSION

Cost for diabetes is largely caused by management of complications. It is important to prevent complications by consequent management of diabetes as well as by primary prevention of its onset.

[Prevalence and temporal trend of known diabetes mellitus: results of the German Health Interview and Examination Survey for Adults (DEGS1)]

The first wave of the "German Health Interview and Examination Survey for Adults" (DEGS1, 2008-2011) allows for up-to-date, representative prevalence estimates of known diabetes amongst the 18- to 79-year-old resident population of Germany. Temporal trends can be shown by comparing the survey findings with those of the "German National Health Interview and Examination Survey 1998" (GNHIES98). The definition of known diabetes was based on self-reports in physician-administered interviews that asked respondents if they had ever been diagnosed with diabetes by a doctor or were on anti-diabetic medication. Overall, diabetes had been diagnosed in 7.2 % of the adults (7.4 % of the women; 7.0 % of the men). The prevalence increased substantially with advancing age and was higher in persons of low than of high socioeconomic status. Prevalence varied depending on the type of health insurance held and was highest amongst those insured with AOK health insurance funds. In comparison with GNHIES98, there was a 38 % increase in prevalence, of which approximately one third is to be attributed to demographic ageing. In the context of other nationwide studies, the results indicate a figure of at least 4.6 million 18- to 79-year-olds having been diagnosed with diabetes at some point. Planned analyses of undiagnosed diabetes will contribute to the interpretation of the observed increase in the prevalence of known diabetes.

[Rehabilitation in geriatric patients after ischemic stroke--a comparison of 2 organisational systems in Germany using claims data of a statutory health insurance fund]

Due to historical aspects in some federal states in Germany rehabilitation of geriatric patients is organized in geriatric departments in hospitals (§ 109 SGB V). In other states rehabilitation of these patients is mainly realized in geriatric rehabilitation facilities outside hospital care after approval by the health insurance (§ 111 SGB V). Thus, it is of interest to compare both types of health care with respect to differences in population characteristics, resource utilization and outcome parameters (i.e., excess costs, rehospitalization, fracture risk and mortality) using a common geriatric indication, the ischemic stroke, as an example.

METHODS

Claims data of the AOK (Local Health Care Fund) from seven federal states in Germany were used. Insured persons with a documented hospital stay with discharge diagnosis cerebral infarction/stroke (ICD-10 I63, I64, below denoted by "ischemic stroke") in 2007 (N=39,887) were included and allocated to the respective form of rehabilitative health care via the OPS (German procedure classification for inpatient procedures) procedure 8-550 (§ 109, N=1,272) or via admission to a geriatric rehabilitation unit within 1 month after hospital discharge (§ 111, N=2,200). All direct costs were ascertained and presented with and without costs of long-term care. Excess costs were calculated as the difference of costs between the first year after insult and the costs in the previous year. Excess costs in the 2 types of care were compared using multivariate quantile regression analysis. Risk of hospitalization (due to ischemic stroke or fracture) and risk of death in a 1-year follow-up was analysed using multivariate cox regression.

RESULTS

Insured members treated according to health care type § 109 were somewhat older (mean: 81 vs. 80 years of age), more frequently female (72 vs. 67%), more often receiving long-term care (27 vs. 19%) and had more often documented sequelae after insult (>=4 diseases 39 vs. 28%). No significant differences in excess costs between both types of care were observed (quantile regression: 25%-percentile-comparison: p=0.49 and 0.11; median-comparison: p=0.99 and 0.13; 75%-percentile-comparison: p=0.13 and 0.30, with and without costs of long-term care, respectively). Moreover, no significant differences were observed related to the outcomes 'rehospitalization due to ischemic stroke' (hazard ratio - HR [95% confidence interval - CI])=1.12 [0.85-1.48], p=0.43) and death (HR [95% CI]=1.03 [0.88-1.20], p=0.75) in the multivariate model (reference: health care type § 111). Insured members in health care type § 109 had a significant lower risk of rehospitalization due to fracture (HR [95% CI]=0.61 [0.40-0.93], p=0.02).

CONCLUSION

According to health care type § 109 and § 111, geriatric patients differ in certain characteristics such as gender, statutory care and documented sequelae after insult. Except for the outcome 'fracture', no significant differences between both types of care have been observed in the selected outcomes. Primary studies with more differentiated data collection may focus on specific treatment and on aims and achievements of rehabilitation.

The distribution of cDNA sequences on field bean chromosomes

Total polyadenylated RNA was isolated from different organs of the field bean by oligo-dT latex particles. Complementary DNA (cDNA) was reverse transcribed from the mRNAs and used as a probe for fluorescent in situ hybridization to metaphase chromosomes. Hybridization signals covered the whole chromosome complement except for late-replicating Giemsa-banded heterochromatin regions, which are composed mainly (or exclusively) of tandemly arranged repetitive sequences.

Alteration of basic chromosome number by fusion-fission cycles

A complete chromosomal fusion-fission cycle is described for the first time. In the field bean, Vicia faba, this cycle probably started with a reversible fusion of two telocentrics giving rise to the standard metacentric chromosome I. The next step was a recent fission of this chromosome into two stable telocentrics eventually followed by a new fusion reconstituting the metacentric chromosome.

Genetic characterization of a reciprocal translocation present in a widely grown barley variety

Artificially induced translocation stocks have been used to physically map the barley genome; however, natural translocations are extremely uncommon in cultivated genotypes. Albacete is a barley variety widely grown in recent decades in Spain and carrying a reciprocal translocation which obviously does not affect its agronomical fitness. This translocation has been characterized by a combination of cytological and molecular genetic approaches. Firstly, recombination frequencies between markers on chromosomes 1H and 3H were estimated to determine the boundaries of the reciprocal interchange. Secondly, 1H-3H wheat barley telosome addition lines were used to assign selected markers to chromosome arms. Thirdly, fluorescence in situ hybridization (FISH) with rDNA probes (5S and 18S-5.8S-26S) and microsatellite probes [(ACT)(5), (AAG)(5) and (CAG)(5)] was used to determine the locations of the translocation breakpoints more precisely. Fourthly, fine-mapping of the regions around the translocation breakpoints was used to increase the marker density for comparative genomics. The results obtained in this study indicate that the translocation is quite large with breakpoints located on the long arms of chromosomes 1H and 3H, between the pericentromeric (AAG)(5) bands and above the (ACT)(5) interstitial distal bands, resulting in the reciprocal translocation 1HS.1HL-3HL and 3HS.3HL-1HL. The gene content around the translocation breakpoints could be inferred from syntenic relationships observed among different species from the grass family Poaceae (rice, Sorghum and Brachypodium) and was estimated at approximately 1,100 and 710 gene models for 1H and 3H, respectively. Duplicated segments between chromosomes Os01 and Os05 in rice derived from ancestral duplications within the grass family overlap with the translocation breakpoints on chromosomes 1H and 3H in the barley variety Albacete.

Colonoscopy and fecal occult blood test use in Germany: results from a large insurance-based cohort

BACKGROUND AND STUDY AIMS

Colonoscopy and guaiac-based fecal occult blood tests (FOBT) are recommended and offered for colorectal cancer (CRC) screening in Germany. We aimed to explore their utilization in a large insurance-based cohort.

PATIENTS AND METHODS

Claims data from between 2000 and 2008 were collected for 170493 individuals who were insured by a large health insurance plan in the federal state of Hesse, Germany. The percentages of individuals who had recently utilized CRC screening-related procedures were calculated. Additionally, multiple test use and identification of CRC screening providers were ascertained.

RESULTS

Following the inception of the current CRC screening program in 2002, colonoscopy utilization rates varied only slightly and FOBT use decreased in individuals aged ≥50 years. At the end of 2008, the age-standardized percentages of individuals who had undergone colonoscopy within ≤10 years were 23% for men and 26% for women. The proportions of individuals who had used FOBT within ≤1 year were 14% for men and 22% for women. Patient education had been utilized by 38% of eligible persons and was increasingly followed by screening colonoscopy. For women, practices that specialized in gynecology were the main providers of FOBT (93%) and patient education (61%).

CONCLUSIONS

This study provides new insights into the inter-related utilization of colonoscopy, FOBT, and patient education in Germany, and may be particularly informative for the design of strategies to increase CRC screening uptake. It indicates that sex differences in CRC screening test use could result to a large extent from general visits to different types of specialist physicians involved in the CRC screening process.

Direct costs of diabetes mellitus in Germany - CoDiM 2000-2007

INTRODUCTION

The prevalence of treated diabetes in Germany and direct health care costs of individuals with diabetes were analysed for the 8-year period from 2000 to 2007, based on administrative data. Special interest was given to the incremental costs attributed to diabetes.

MATERIAL AND METHODS

An 18.75% sample of all members of a large local German statutory health insurance provider, "AOK - Die Gesundheitskasse" in the federal state of Hesse was analysed with regard to cases of treated diabetes. To assess the incremental diabetes-related direct costs, the cost data of individuals with diabetes was compared to that of an age- and sex-matched group of persons without diabetes. Prevalence and costs were standardized according to the gender and age distribution of the German population.

RESULTS

Between 2000 and 2007, the administrative prevalence of treated diabetes rose continuously in Germany, from 6.5 to 8.9% (+36.8%). The number of patients treated with 'insulin' or 'insulin & oral antidiabetic agents' increased by +54.7 and +61.7%, respectively. Direct costs per patient with diabetes, calculated using the unit costs reimbursed by statutory health and nursing care insurances, rose from € 5 197 to € 5 726 (+10.2%). Incremental per-capita costs were € 2 400 in 2000 and € 2 605 in 2007 (+8.5%). However, the total direct cost burden of diabetes in Germany grew from € 27.8 billion to € 42.0 billion (+51.1%). The incremental diabetes-related cost burden increased from € 12.9 billion to € 19.1 billion (+48.6%).

CONCLUSIONS

There was a continuous increase in the prevalence of diabetes in Germany during the 8-year period. Although there was only a modest increase in annual diabetes-related per-capita costs, total healthcare expenditure rose substantially due to the growing number of patients being treated for diabetes.

[Differences in antibiotic prescribing between general practitioners and pediatricians in Hesse, Germany]

BACKGROUND

A careful consideration of antibiotic prescription is necessary due to emerging antibiotic resistance. Differences in prescription rates between physician groups have only rarely been examined. We compared the prescription of antibiotics for systemic use in children between pediatricians and general practitioners (GPs).

METHOD

Data source was the statutory health insurance sample AOK Hesse/KV Hesse. Overall, 47,033 insured children in 2006 between 2 and 17 years of age were included in the analysis. Odds ratios (OR) and 95% confidence intervals (CI) for an antibiotic prescription were calculated by logistic regression adjusted for confounders, comparing pediatricians with GPs. Diagnosis-specific models were constructed.

RESULTS

GPs and pediatricians prescribed 79.3% of all antibiotics in 2006 (40.6% and 38.7%, respectively). Significantly decreased ORs for an antibiotic prescription were observed for pediatricians, with OR (95% CI) of 0.46 (0.43-0.49), 0.40 (0.30-0.54) and 0.40 (0.30-0.53) for respiratory tract infections, urinary tract infections and nonsuppurative otitis media, respectively. No significant associations were observed assessing scarlet fever, pneumonia and suppurative otitis media, respectively.

CONCLUSION

In this retrospective analysis, pediatricians were associated with a lower antibiotic prescription rate regarding diagnoses where antibiotic therapy is not clearly indicated. However, in diagnoses where antibiotic therapy is clearly indicated, no differences in prescription rates between pediatricians and GPs were observed. Further studies are warranted to gain insight into different treatment strategies between different groups of medical practitioners.

[Herpes zoster in Germany. A retrospective analyse of SHL data]

The incidence of herpes zoster in the elderly (50 years and older) 2004 in Germany was determined by retrospectively analysing representative treatment data of the statutory health insurance sample of AOK Hesse/KV Hesse. The overall observed incidence rate of herpes zoster was 9.4 cases per 1,000 person-years (PY). 10.1% of herpes-zoster-patients suffered at least 1 month from pain, the so called postherpetic neuralgia (PHN1), 6.9% had at least 3 months pain (PHN3). Incidence rate of herpes zoster rose markedly with age: from 6.8 per 1,000 PY in 50 to 54 year-olds to 12.4 PY in persons 80 years and older. Incidence rate in the immunocompromised was higher (11.6 per 1,000 PY) than in the immunocompetent (9.1 per 1,000 PY). According to a standardized extrapolation of the sample to the German population, about 300,000 persons 50 years and older suffered from acute herpes zoster on the year 2004 in Germany.

[Impact of demographic changes on health care expenditure in Germany: an analysis considering the expenditures of decedents]

The purpose of this study was to evaluate the impact of demographic changes on future health care expenditure of the German social health insurances considering the expenditures of survivors and decedents by age. The study analysed data from 269,646 members up to the age of 99 years of the AOK - one of Germany's largest social health insurers - in the State of Hesse in 2000/2001. In order to determine future health care expenditures, per-capita expenditures by age for outpatient, inpatient, rehabilitation, and nursing services of survivors and decedents (death within the next 12 months) were multiplied by the estimated number of survivors and decedents by age in Germany in 2020, 2035 und 2050. Expenditures for all ages were summed together. The paper shows that demographic changes until 2050 will lead to an increase of health care expenditures by 20% in total or less than 1% annually. Considering the future re-duction in workforce, demographic changes until 2050 will result in an estimated increase in health care expenditures per employee by about 57% (undifferentiated model). Considering the cost of survivors and decedents separately, this increase will amount to 50%. Hence, undifferentiated models overestimate the impact of demographic changes by about 10%.

[Persons requiring long-term care: Recommendation and utilization of rehabilitative therapies]

In Germany all members of the statutory health insurance are also compulsory members of the nursing care insurance which financially supports nursing care at home and in nursing homes. Benefits are provided dependent on a standardized medical examination performed at the home of the applicants by trained physicians or nurses of the health insurances' medical service (MDK). The benefits are granted to those persons who are limited in the performance of activities of daily living due to physical, cognitive or mental disorders. In the German Code of Social Law regulating the long-term care system, one important entitlement is "rehabilitation before long-term care". It aims at maintaining life of disabled persons in their familiar surroundings as long as possible. Up to now in the nursing care insurance this aim has been implemented insufficiently. The objective of this study was therefore to investigate the frequency of suggested ambulatory rehabilitation, which is recommended by the MDK at the examinations, and the following prescription of ambulatory rehabilitation, issued by an office-based physician. The database included the medical examinations of the years 2001 to 2002 linked to a random sample of persons insured in a statutory sickness fund in the German federal state of Hesse. Nursing care-related information including recommended rehabilitation therapy was derived from the medical examinations. Insurance data provided information on prescriptions. Data of 7,840 persons could be analyzed. Rehabilitative therapy was recommended in 15% of the nursing care applicants, mostly physiotherapy (ca. 90%). Persons receiving the recommendation were mainly male, they were younger, were more disabled, had less often a diagnosis of the ICD-10 chapter "symptoms and abnormal clinical and laboratory findings" or "mental and behavioral disorders", live less often alone and were more restricted in their motion compared to persons without recommendation for rehabilitative therapy. Only 55.3% of the persons with a recommendation for physiotherapy and only one-third with a recommendation for occupational therapy or logopedics received a prescription for the respective therapy in the following three months after examination. The age younger than 80 years, professional care, no home care, and-as the strongest item-preceding therapy were positively related to receiving a prescription. These findings show that disabled persons have the capability for prevention and rehabilitation, but it is used in only half of them. One possible reason might be the financing of the remedies, which burdens the budget of the health insurance, where instead the nursing care insurance benefits from the possible delay of the utilization of nursing care.
