[Distal Forearm Fractures in Children and Adolescents: Frequency and Health Care Provision in Germany]. / Distale Unterarmfrakturen im Kindes- und Jugendalter: Häufigkeit und Versorgungsgeschehen in Deutschland.

BACKGROUND: Despite their frequent occurrence, there are no standardized recommendations for treating distal forearm fractures in growing children. Due to the marked remodelling capacity, conservative therapy is the first choice treatment of fractures in children. However, there are concerns that the possibilities of conservative treatments are often underestimated. Information on the health care situation in Germany on this issue is scarce. METHODS: The present study is based on routine data of a German Health Insurance fund, the Gmünder ErsatzKasse (GEK). Data on diagnoses and treatment of insured persons aged 0-15 years were analysed for the period from 01/07/2005 to 30/06/2009 regarding the frequency of distal forearm fractures and fracture treatment. RESULTS: The overall incidence rate was 56.8 per 10 000 person-years (64.5 in boys; 48.7 in girls). Most of the distal forearm fractures occurred during spring and summer months. The majority of the fractures were immobilized in a plaster cast (84.2%; n=2 609). 8.7% (n=270) of the fractures were treated with closed reduction and percutaneous osteosynthesis. 4.5% (n=138) were treated with closed reduction without any form of osteosynthesis. Only 1.4% (n=43) of the fractures were treated with open reduction. CONCLUSION: Our study shows that boys suffer distal forearm fractures more frequently than girls and that incidences tend to be higher in older children. In addition, analyses indicated seasonal differences between the age groups. In childhood, distal forearm fractures were treated more often conservatively than operatively. However, it was remarkable that fractures in the case of closed reduction were more frequently fixed with an osteosynthesis than just by immobilization in a plaster cast.

[Health services research : Definition, objective, method and perspectives]. / Versorgungsforschung : Definition, Gegenstand, Methodik und Perspektiven.

This overview article highlights the central role of health services research (HSR) for the further development of the healthcare system. As a young scientific discipline in Germany, HSR covers five important elements with different weighting in different definitions, which are elaborated in some detail in this article: patient orientation, results and outcome orientation at the patient and population levels, implementation perspectives and context relation, complex interventions and improvement, multidisciplinarity and multiprofessionalism. One of the fundamental pillars of HRS is related to the insufficient implementation of scientifically proven treatment methods and improvement strategies into routine patient care. Healthcare research is therefore the so-called second translation of clinical trials in the routine daily care (from bedside to practice) after the first translation from bench to bedside. The scientific methods used in HSR clearly extend beyond the spectrum of (clinical) epidemiology. The methodological standards are developed as consensus memoranda of members of the German network of HSR, which serve as orientation points for qualitatively good HSR. Finally, various perspectives for the long-term safeguarding and improvement of the quality of HSR in Germany are proposed.

[Assessing the added benefit of new ophthalmic drugs : Which additional insights can be extracted from the early benefit assessment?] / Bewertung des Zusatznutzens neuer Ophthalmika : Welchen Erkenntnisgewinn liefert die frühe Nutzenbewertung?

Until now six ophthalmic agents have undergone the German early benefit assessment according to § 35a Social Security Code (SGB) V in a total of eleven indications. Only one agent (ocriplasmin) was recognized by the Federal Joint Committee as having an added benefit based on submitted study data for a subpopulation (indication of a considerable added benefit, limited for 5 years) and another agent, idebenone, received an added benefit due to its orphan drug designation (proof of a not quantifiable added benefit, limited for 2 years). All remaining agents (aflibercept, bromfenac, nepafenac and tafluprost/timolol) were not recognized as having an added benefit. The analysis showed that there was a lack of suitable evidence. Some reasons for the inappropriateness of the conducted trials for the usage in the early benefit assessment are the comparative therapy, the patient population included or the dosage regimens. For two agents (bromfenac and nepafenac) the pharmaceutical company did not even submit a value dossier. The examples from ophthalmology illustrate the methodological and procedural shortcomings of the assessment process and that results of an early benefit assessment should be interpreted with caution.

Prevalence and comorbidities in adults with psoriasis compared to atopic eczema.

BACKGROUND: Most data suggesting an association between psoriasis and cardiovascular disease (CVD) have come from specialized populations at either low or high risk of CVD. Atopic dermatitis (AD) has been associated with a number of modifiable risk factors, particularly obesity. There has been a recent controversy on the suggestion that associations with comorbidities in psoriasis may be due to overreporting or biased by disease severity and therefore not necessarily representative of the general psoriasis population. OBJECTIVES: To evaluate the prevalence of AD and psoriasis and to compare the prevalence rates of comorbidities based on a large sample of health insurance data. METHODS: Data were collected from a database of non-selected individuals from a German statutory health insurance organization that covers all geographic regions. Individuals identified by International Classification of Diseases (ICD)-10 codes applied to all outpatient and inpatient visits in the year 2009. Comorbidities were evaluated by ICD-10 diagnoses. RESULTS: The database consisted of 1 642 852 members of a German statutory health insurance. Of 1 349 671 data sets analyzed, 37 456 patients ≥18 years were diagnosed with psoriasis (prevalence 2.78%), and 48 140 patients ≥18 years of age were diagnosed with AD, equivalent to a prevalence of 3.67%. Patients with psoriasis showed increased rates of comorbidities in all age groups. Comorbidities related to the metabolic syndrome including arterial hypertension [prevalence ratio (PR), 1.94; 95% confidence interval (CI), 1.90-1.98], hyperlipidaemia (PR, 1.77; 95% CI, 1.73-1.81), obesity (PR, 1.74; 95% CI, 1.69-1.79) and diabetes mellitus (PR, 1.88; 95% CI, 1.83-1.94) were significantly more common among patients with psoriasis compared to AD. CONCLUSIONS: Diseases forming part of the metabolic syndrome showed significant lower prevalence rates in patients with AD than in patients with psoriasis. Within the limitations of secondary healthcare data, our study disproves the suggestion that associations with comorbidities in psoriasis may be biased by a higher degree of severity or overreporting.

[Drug assessment: IQWiG, G-BA, and an international comparison]. / Arzneimittelbewertung: IQWiG, G-BA und internationaler Vergleich.

BACKGROUND: Since the Pharmaceutical Market Restructuring Act (Arzneimittelmarktneuordnungsgesetz-AMNOG) went into effect on 1 January 2011, new medicinal products provided under statutory health insurance have to undergo an early benefit assessment, prepared on the basis of scientific dossiers drawn up by the German Institute for Quality and Cost Effectiveness in the Health Care Sector (Institut für Qualität und Wirtschaftlichkeit im Gesundheitswesen-IQWiG) and adopted by the Federal Joint Committee (Gemeinsamer Bundesausschuss-G-BA). These assessments, in which the additional benefit of a product is compared with existing standard therapy and ultimately has a bearing on price negotiations with the pharmaceutical companies, are carried out on the basis of clinical trial data presented by the latter. Results so far, however, show that the IQWIG's and the G-BA's assessments often vary, although both bodies have the same documentation. Such differences can also be observed on an international level. OBJECTIVES: Using selected examples, the differences in the assessments of new pharmaceuticals are presented and reasons for national and international deviations are discussed. CURRENT DATA: As yet, no systematic comparative analysis has been made of assessments of medicinal products by the respective institutions. For this reason, it was not possible to make a systematic selection of pharmaceuticals, and the cases were instead selected according to available information. CONCLUSIONS: An overview of the results shows that the diverging assessments-both national and international-are not always scientifically justifiable, but rather appear to be influenced by the-not always transparent-framework parameters of the respective health system. Assessments are always shaped by certain perspectives on the data and results under scrutiny. It would undoubtedly be worthwhile to evaluate these influences to gain a better understanding of the reasons for national and international discrepancies in the assessment of additional therapeutic value of new pharmaceutical products.

[Age 70 and older a criterion for inclusion - not exclusion]. / 70 plus als Einschlusskriterium - nicht als Ausschluss.

BACKGROUND: Although older people are frequently prescribed more drugs than younger people, they are rarely included in clinical trials. Elderly patients often suffer from multimorbidity and are prescribed many drugs simultaneously. With age, physiological changes occur that can affect the pharmacokinetics and pharmacodynamics of the drugs used, e.g., changes in the duration of action. There are several problematic implications to this, particularly relating to tolerability and possible negative effects for patients. OBJECTIVES: Not only are guidelines for the treatment of elderly patients lacking, but also basic information about efficacy, tolerability, and interactions of drugs that are commonly prescribed to the elderly often missing. Physicians sometimes have no choice but to estimate the correct dosages for the elderly. METHODS: Evaluations of secondary data and clinical trials, discussion, and analysis of basic research work on the basis of expert analysis. RESULTS: There are very few clinical trials that include people over the age of 70. On the one hand, elderly people receive more drug prescriptions due to multimorbidity, compared with younger people, while on the other hand the risk of adverse drug reaction increases for precisely these individuals. CONCLUSIONS: In order to improve treatment safety in older people in terms of duration and dosage, randomized control trials (RCT) are essential to provide evidence of the benefits of a drug to patients. For this reason, the call for clinical trials after as well as before authorization, on patients treated with these drugs-and that especially means elderly patients-is long overdue.

[Pain medication in nursing home residents with and without cancer. Most frequently with metamizole]. / Schmerzmittelversorgung von Pflegeheimbewohnern mit und ohne Krebserkrankung. Am häufigsten mit Metamizol.

BACKGROUND: Pain is a highly prevalent symptom in nursing home residents. The analgesic pharmacotherapy of older adults is associated with challenges; however, studies from Germany examining the prescription pattern of analgesics in nursing home residents are rare. OBJECTIVES: This study was carried out to examine the prescription of analgesics in nursing home residents with and without the diagnosis of cancer. MATERIAL AND METHODS: Using health insurance claims data persons aged ≥ 65 years who were newly admitted to a nursing home between 2004 and 2009 and who survived at least the first 90 days after admission were included in the study. Cancer was identified by outpatient diagnoses of malignant neoplasms (ICD-10: C00-C97). Prescription drugs within the first 90 days after admission to a nursing home were analyzed which means that aspirin and acetaminophen were not taken into account. RESULTS: A total of 5549 nursing home residents were included, who were on average 81.5 years old (56.8 % females). More than half (53.5 %) were assigned to care level I and 781 (14.1 %) were diagnosed with cancer. The study cohort received on average 7.8 different medications (with vs. without cancer: 8.6 vs. 7.6, respectively) and 43.8 % had prescriptions for analgesics (with vs. without cancer: 52.5 vs. 42.3 %, respectively). A total of 37.1 % were taking WHO step 1 analgesics (step 2: 11.4 % and step 3: 9.2 %). The proportion of persons receiving metamizole (dipyrone) was 28.3 % (with vs. without cancer: 35.6 vs. 27.1 %, respectively). Regarding all prescriptions, metamizole was by far the most frequently prescribed medication in nursing homes followed by melperone and omeprazole. CONCLUSION: Approximately one third of nursing home residents received metamizole and most were long-term prescriptions. Considering that metamizole is associated with potentially life-threatening adverse effects, caution is indicated particularly when prescribed over long periods.

Who gets dipyrone (metamizole) in Germany? Prescribing by age, sex and region.

WHAT IS KNOWN AND OBJECTIVE: Metamizole (dipyrone) is an analgesic that has been the focus of considerable controversy regarding its safety. Because of potentially life-threatening blood disorders such as agranulocytosis, it has been withdrawn in many countries but not in Germany, where prescribing even increased over recent years. We aimed to evaluate prescribing of metamizole in Germany with respect to age, sex and regional variations. METHODS: Using data of a statutory health insurance, we analysed a cohort of 1·7 million persons who were insured at least 1 day in each quarter of 2009. Outcome of interest was the outpatient prescription prevalence, for example the proportion of persons receiving at least one prescription of metamizole. RESULTS AND DISCUSSION: A total of 6·8% received metamizole with a higher prescribing prevalence in females (7·8% vs. 6·0%). The prevalence increased with age up to 26·7% in persons ≥85 years (men: 21·1%; and women: 30·4%). We found large regional variations with higher prevalences in the northern part of Germany. Most of the prescriptions were issued by general practitioners (78·9%). 58·3% were liquid oral formulations with considerable regional variations ranging between 32·3% in Mecklenburg-West Pomerania and 67·3% in North Rhine-Westphalia. Overall, liquid oral forms are much more often prescribed in the western than in the eastern part of Germany. WHAT IS NEW AND CONCLUSION: Metamizole - a drug with a relatively narrow indication - is often prescribed in Germany with relevant differences by age, sex and region. Qualitative studies should clarify reasons for this. Further quantitative research should investigate small-area variations, indications and treatment durations.

Underuse of proton-pump inhibitors in older patients newly starting NSAID treatment.

OBJECTIVE: Proton pump inhibitors (PPIs) are recommended for the prevention of traditional non-steroidal anti-inflammatory drugs (tNSAIDs)-related ulcer complications in high-risk patients. We aimed to study to which extent older persons initiating tNSAIDs with and without oral corticosteroids receive PPIs and whether sex and age influence treatment. METHODS: We analysed claims data of the German health insurance company BARMER GEK, covering about 9 million persons. A cohort of new users of tNSAIDs aged 65 years and older starting treatment from 1 January 2011, through 1 December 2012 was included. Concurrent use of oral corticosteroids was assessed within the 28 days before the index date. Persons were categorised as users of PPIs if they filled a prescription within 28 days before or after the index prescription. RESULTS: A total of 83,326 persons met the inclusion criteria (64.1% females; mean age: 74.7 years). Of these new users of tNSAID, 27.8% received PPIs within 28 days before or after the index date (females: 29.4% and males: 25.0%). Of the 2857 persons with concurrent prescriptions of oral corticosteroids, 42.8% also received PPIs (females: 43.4% and males: 41.8%). An increase in prescribing of PPIs with age was found in all new users as well as in those concurrently receiving oral corticosteroids. CONCLUSIONS: We found that gastroprotective agents are not prescribed to older new users of tNSAIDs as recommended. When compared with earlier studies, adherence to guidelines still remains low.

[Economic Evaluation of Integrated Care Systems - Scientific Standard Specifications, Challenges, Best Practice Model]. / Ökonomische Erfolgsmessung von integrierten Versorgungsnetzen - Gütekriterien, Herausforderungen, Best-Practice-Modell.

PURPOSE: Transparency of economic performance of integrated care systems (IV) is a basic requirement for the acceptance and further development of integrated care. Diverse evaluation methods are used but are seldom openly discussed because of the proprietary nature of the different business models. The aim of this article is to develop a generic model for measuring economic performance of IV interventions. METHODS: A catalogue of five quality criteria is used to discuss different evaluation methods -(uncontrolled before-after-studies, control group-based approaches, regression models). On this -basis a best practice model is proposed. RESULTS: A regression model based on the German morbidity-based risk structure equalisation scheme (MorbiRSA) has some benefits in comparison to the other methods mentioned. In particular it requires less resources to be implemented and offers advantages concerning the relia-bility and the transparency of the method (=important for acceptance). Also validity is sound. Although RCTs and - also to a lesser -extent - complex difference-in-difference matching approaches can lead to a higher validity of the results, their feasibility in real life settings is limited due to economic and practical reasons. That is why central criticisms of a MorbiRSA-based model were addressed, adaptions proposed and incorporated in a best practice model: Population-oriented morbidity adjusted margin improvement model (P-DBV(MRSA)). CONCLUSION: The P-DBV(MRSA) approach may be used as a standardised best practice model for the economic evaluation of IV. Parallel to the proposed approach for measuring economic performance a balanced, quality-oriented performance measurement system should be introduced. This should prevent incentivising IV-players to undertake short-term cost cutting at the expense of quality.

[Increased prescribing of proton pump inhibitors in ambulatory care over the years 2005 - 2013]. / Steigende Verordnungszahlen von Protonenpumpenhemmern im ambulant-ärztlichen Bereich über die Jahre 2005 - 2013.

BACKGROUND: In many countries, proton pump inhibitors (PPIs) are increasingly prescribed over recent years and there is evidence of overprescribing. The aim of this article was to analyse the utilization of PPIs in Germany with respect to age and sex and to study regional variations as well as differences regarding medical specialties. METHODS: We used claims data of the BARMER GEK for the years 2005 - 2013. Main outcome was the prescribing prevalence, e. g., the proportion of persons with at least one prescription of PPIs in the corresponding year. In addition, the prescribing medical specialties and regional differences were studied for the year 2013. RESULTS: Over the years 2005 to 2013, the prescribing prevalence increased linearly from 8.2 % to 16.2 % (+ 97 %). Females were more often affected than males. Prevalences were also increasing with age (0 - 5 years: 0.2 % to 95 + years: 39.5 % in 2013). Regional differences were comparatively low (interquartile range of the postal code regions: 15.0 - 17.0 %). General practitioners prescribed a large majority of PPIs (90.1 %) with even higher proportions in the older age (98.1 % in persons aged 95 + years). CONCLUSIONS: The proportion of persons receiving PPIs has doubled over the past 9 years. Physicians should review their prescribing habits critically on a periodic basis.

[The importance of an early accompanying evaluation of new care forms for the development of indicators for quality assurance in outpatient psychiatric integrated care]. / Die Bedeutung einer frühzeitigen begleitenden Evaluation für die Ableitung von Indikatoren zur Qualitätsmessung in der ambulanten psychiatrischen Integrierten Versorgung.

Aim of this contribution is to illustrate the imp-ortance of an early accompanying evaluation of new care forms for the development of indicators. The illustration uses the experience of the accompanying evaluation of the integrated care model for optimisation of outpatient psychiatric care. For the integrated care model we could develop potential indicators by using medical-psychiatric and insured-related routine data, but all potential indicators need further development to enable reliable statements about achieved quality targets. It is shown that the development of indicators in the outpatient psychiatric integrated care is affected by many different factors such as vague target agreements in the contract and missing contractual agreements for the data. As a result it is illustrated that in this project the evaluation was introduced after implementation of this new form of care and the already established contract and the data management impeded the development of indicators.

[Health services research in urology: basis and examples]. / Versorgungsforschung in der Urologie : Basis und Beispiele.

Health services research investigates the supply of individuals and the population with health-relevant products and services under routine daily conditions. It must be understood as a cyclic process whereby an image of the current situation should always be the starting point but which can, for example generate hypotheses for new approaches in clinical research. Health services research cannot be reduced to a specific method but is primarily defined by the question to be answered. The use of health insurance data in particular play a major role in health services research.

[Sex-specific differences in drug utilisation in different phases of life]. / Geschlechtsspezifische Inanspruchnahme bei der Arzneimittelversorgung in verschiedenen Lebensphasen.

The aim of the present study is to analyse sex-specific differences in drug utilisation during different phases of life using relevant diseases as examples. We used a cohort of 1.7 million subjects who were insured with the Gmünder ErsatzKasse (GEK), a German health insurance fund, for at least one day in all four quarters of 2009. We analysed subjects with outpatient diagnoses of the following diseases: attention-deficit/hyperactivity disorder (ADHD) (0-17 years), hypothyroidism (18-49 years), osteoporosis (50-79 years) and coronary heart disease (80 + years). Analysis was performed on an active-substance level. A number of differences were observed in drug treatment for the selected diseases (for example, substances for ADHD were prescribed more often in males and for hypothyroidism more often in females), as well as in prescribing practices relating to other drugs used in these groups. However, clear explanations for these differences, such as drug approval status, were not always apparent.

[Benzodiazepine hypnotics, zolpidem and zopiclone on private prescriptions: use between 1993 and 2012]. / Benzodiazepinhypnotika, Zolpidem und Zopiclon auf Privatrezept : Verbrauch zwischen 1993 und 2012.

OBJECTIVE: Previous analyses showed that benzodiazepine hypnotics as well as zolpidem and zopiclone (Z drugs) were increasingly being dispensed on so-called private prescriptions (Privatverordnungen) in Germany. Any doctor can provide private prescriptions for prescription drugs which are fully funded by the patient. This study aimed to analyze the amount of private prescriptions for hypnotics over the last 20 years. METHODS: We compared utilization data from statutory health insurance claims with purchasing statistics from community pharmacies for the years 1993-2012. RESULTS: From 1993 to 2012 purchased packages of hypnotics decreased (from 14.9 to 9.9 million). Benzodiazepines were dispensed less and Z drugs more often. In 2012 zopiclone (4.3 million packages of which 42.7 % were private prescriptions), zolpidem (3.6 million, 57.6 %) and lormetazepam (0.8 million, 57.8 %) were most often prescribed. CONCLUSION: Trends in prescribing Z drugs are particularly noticeable whereby zolpidem was dispensed more often on private prescriptions than zopiclone. This seems to be further evidence for a higher dependence and abuse potential of zolpidem.

[The epidemiology of chronic diseases and long-term care: results of a claims data-based study]. / Die Epidemiologie von chronischen Krankheiten und Pflegebedürftigkeit : Eine Untersuchung auf der Basis von Abrechnungsdaten der gesetzlichen Krankenversicherung.

BACKGROUND: It is generally assumed that chronic diseases and multimorbidity increase the risk of long-term care. Nevertheless, a systematic study on the nature and the prevalence of those diseases associated with long-term care has not been yet undertaken in Germany. MATERIALS AND METHODS: The study was perfomed using claims data of one nationwide operating statutory health insurance company in 2006. Inclusion criteria were age ≥ 65 years, minimum of 1 out of 46 diagnoses in a minimum of three quarters of the year (n = 8,678). A comparison group was formed with n = 114,962. We calculated prevalences and relative risks -using nominal regression- to determine influential factors on long-term care. RESULTS: A small number of diseases (e.g. dementia, urinary incontinence, chronic stroke and cardiac insufficiency) show high prevalences (> 20%) among long-term care users and at the same time great prevalence differences between users and non-users CONCLUSION: These data are important for improving medical and nursing care of long-term care users. Further research is needed with regard to the question by which mechanisms those diseases produce disability and frailty, thus leading to long-term care requirements.

[Social and economic consequences of night-time aircraft noise in the vicinity of Frankfurt/Main airport]. / Soziale und ökonomische folgen nächtlichen fluglärms im umfeld des flughafens Frankfurt/Main.

A prospective calculation of disease-related social and economic costs due to night-time aircraft noise in the vicinity of Frankfurt/Main airport was performed for the calendar years 2012-2021. It was based on risk estimates for a variety of diagnostic entities (cardiovascular disease, depression, psychosis, diabetes mellitus, dementia and Alzheimer's disease, all cancers except malignancies of the respiratory system) from a previous case-control study on more than 1 million persons enrolled in compulsory sickness funds in the vicinity of the Cologne-Bonn airport, on disease-related cost estimates performed by the German Federal Statistical Office for the calender years 2002-2008, and calculations of the population exposed to night-time aircraft noise in the vicinity of Frankfurt/Main airport (2005 aircraft routes and flight frequencies). Total estimated costs came to more than 1.5 billion € with an excess of 23 400 cases of diseases treated in hospitals and of 3 400 subsequent deaths.

Variation in antibiotic prescriptions: is area deprivation an explanation? Analysis of 1.2 million children in Germany.

PURPOSE: Inadequate use of antibiotics can lead to problems such as resistance. Overuse is especially a problem for children, since they are more affected by acute (often virus-caused) infections. While the problem has been addressed internationally over the past several years, regional variations in prescriptions are striking. Therefore, the present study aims to analyze regional variations in antibiotic prescription on a district level in Germany and tries to identify reasons for those variations through adding possible influencing factors to the analysis on individual and district levels. METHODS: We analyzed 1.2 million children insured in a German health insurance fund. Antibiotic prescriptions were quantified in 2010 and reasons for prescriptions were analyzed in multilevel regressions based on the district of residence, regional deprivation, and age and sex of the child. RESULTS: Thirty-six percent of all children aged 0-17 years received an antibiotic prescription in 2010. In the south, prevalences are generally lower, and also to the very north. The highest prevalences are found in the close-to-border districts in the west, as well as in a band throughout the middle of Germany, in rather low population density areas. Regional variation in the prevalence range from 19 to 53 % between districts. Regional deprivation can explain part of this variation. CONCLUSIONS: Including area deprivation measures helped identify an influence of especially regional income and occupational deprivation on antibiotic prescriptions for children. Regional analysis such as this can help identify specific regions and groups of persons to address information programs on the risks of preventable antibiotic consumption and alternative treatment methods.

[Prescription of high-potency opioids in 2011]. / Verordnung von starken Opioiden im Jahr 2011.

BACKGROUND: The aim of this study was to analyze the prescription of high-potency (WHO step III) opioids with respect to regional differences and to assess the proportion of opioid-naïve new users of transdermal fentanyl. METHODS: Prescription claims data of the largest single German health fund (BARMER GEK) with 9.1 million insured persons from the year 2011 were used. For new users of transdermal fentanyl who had had no prescription in the preceding 6 months it was studied whether they had received other high-potency or low-potency opioids before. RESULTS: A total of 18.9 million defined daily doses (DDD) of high-potency opioids were included corresponding to a mean of 208.6 DDD per 100 persons. Significant regional differences were found with lower values in the south, ranging from 145.9 DDD in Baden-Württemberg to 259.5 DDD per 100 persons in Lower Saxony. Fentanyl was the most frequently used step III opioid (40.8% of DDDs) which is nearly only given transdermally. Of the 11,184 patients with new use of transdermal fentanyl 80.7% had received no other high-potency opioid before and 52.9% had received neither low-potency nor high-potency opioids before. The first prescription exceeded the smallest available dose of 12.5 µg/h for over half of the patients starting treatment. CONCLUSIONS: Although oral morphine, oxycodone and hydromorphone are recommended as first-line step III opioids, transdermal fentanyl seems to be prescribed too often as the first choice and might not be appropriate.

Healthcare utilization of back pain patients: results of a claims data analysis.

OBJECTIVES: The high life-time prevalence of chronic back pain (25-30% according to surveys in small samples) suggests that it may be a major source of healthcare cost and that prevention of chronic back pain may be both ethically and economically recommendable. To obtain valid economic data on the cost of back pain in Germany, a retrospective claims data analysis was performed. METHODS: Using data from 2006 of 5.2 million beneficiaries of a German statutory health insurance fund (DAK Unternehmen Leben) covering ~7% of the German population, mean value analyses report on key healthcare utilization figures from a sickness funds? perspective. In contrast to other studies, cost data are primary data and not extrapolated, but clinical characteristics include surrogate markers as no clinical case descriptions were available. RESULTS: Based on previously investigated diagnosis patterns three types of back pain could be identified: (other) specific back pain (n=211,216), pain due to spinal disk disease (n=195,712), and non-specific back pain (n=534,272). Of all back pain patients, 25.8% were identified as at risk to develop chronic pain, where only 2.6% were detected as patients with chronic back pain. Mean resource utilization and related healthcare costs were significantly higher for beneficiaries with indicators for chronic back pain than for beneficiaries with only risk factors for developing chronic back pain. This especially holds for outpatient analgesic prescriptions (p<0.05), for in-hospital multimodal pain therapy (p<0.05), for in-hospital care in general (p<0.05), as well as for direct cost of care (p<0.05). CONCLUSION: The results show the potential that could be made accessible by an early detection of back pain patients who bear a risk of pain becoming chronic, both in terms of quality-of-life as well as in financial terms.
