[Development of quality indicators for the care of patients with chronic kidney disease : Results of a structured consensus process using the Delphi technique]. / Entwicklung von Qualitätsindikatoren für die Versorgung von Patient:innen mit chronischer Nierenerkrankung : Ergebnisse einer strukturierten Konsensfindung mittels Delphi-Verfahrens.

BACKGROUND: Chronic kidney disease (CKD) is a common condition, especially in the elderly. In order to prevent progression and complications of the disease, guideline-adherent outpatient care of patients with CKD should be prioritized. Quality indicators (QIs) can be used to measure and evaluate the quality of ambulatory care for patients with CKD. QIs specifically made for evaluating CKD care in Germany are not yet available. The goal of this work was to develop QIs for the quality assessment of outpatient care for patients over the age of 70 with CKD not requiring dialysis. MATERIALS AND METHODS: QIs were operationalized from the recommendations of the German national guideline for CKD and others were proposed based on a published review of international QIs. The resulting QIs were divided into sets based on routine data (e.g., health insurance billing data) and data collection in practices (chart review). A panel of experts from various disciplines as well as a patient representative evaluated the proposed QIs in a two-stage Delphi process via online survey in October 2021 and January 2022 and a final consensus conference in March 2022. In addition, ranking lists of the most important QIs from each set were created. RESULTS: An incidence indicator and a prevalence indicator were established; these were not subject to vote. Further, 21 QIs were voted upon by the expert panel. The seven most important QIs in each set (billing data or chart review) were selected. Only one QI was rated by the expert panel as not suitable for additional use in adults under the age of 70 years. DISCUSSION: The QIs will enable the evaluation of the quality of outpatient care for patients with CKD with the long-term aim of optimizing guideline-adherent outpatient care.

Monitoring and management of chronic kidney disease in ambulatory care - analysis of clinical and claims data from a population-based study.

BACKGROUND: Although chronic kidney disease (CKD) is highly prevalent in the general population, little research has been conducted on CKD management in ambulatory care. Objective was to assess management and quality of care by evaluating CKD coding in ambulatory care, patient diagnosis awareness, frequency of monitoring and whether appropriate patients are referred to nephrology. METHODS: Clinical data from the population-based cohort Study of Health in Pomerania (SHIP-START) were matched with claims data of the Association of Statutory Health Insurance Physicians. Quality of care was evaluated according international and German recommendations. RESULTS: Data from 1778 participants (56% female, mean age 59 years) were analysed. 10% had eGFR < 60 ml/min/1.73m2 (mean age 74 years), 15% had albuminuria. 21% had CKD as defined by KDIGO. 20% of these were coded and 7% self-reported having CKD. Coding increased with GFR stage (G3a 20%, G3b 61%, G4 75%, G5 100%). Serum creatinine and urinary dip stick testing were billed in the majority of all participants regardless of renal function. Testing frequency partially surpassed recommendations. Nephrology consultation was billed in few cases with stage G3b-G4. CONCLUSION: CKD coding increased with stage and was performed reliably in stages ≥ G4, while CKD awareness was low. Adherence to monitoring and referral criteria varied, depending on the applicability of monitoring criteria. For assessing quality of care, consent on monitoring, patient education, referral criteria and coordination of care needs to be established, accounting for patient related factors, including age and comorbidity. TRIAL REGISTRATION: This study was prospectively registered as DRKS00009812 in the German Clinical Trials Register (DRKS).

Referral criteria for chronic kidney disease: implications for disease management and healthcare expenditure-analysis of a population-based sample.

BACKGROUND: Clinical practice guidelines recommend specialist referral according to different criteria. The aim was to assess recommended and observed referral rate and health care expenditure according to recommendations from: • Kidney Disease Improving Global Outcomes (KDIGO,2012) • National Institute for Health and Care Excellence (NICE,2014) • German Society of Nephrology/German Society of Internal Medicine (DGfN/DGIM,2015) • German College of General Practitioners and Family Physicians (DEGAM,2019) • Kidney failure risk equation (NICE,2021) METHODS: Data of the population-based cohort Study of Health in Pomerania were matched with claims data. Proportion of subjects meeting referral criteria and corresponding health care expenditures were calculated and projected to the population of Mecklenburg-Vorpommern. RESULTS: Data from 1927 subjects were analysed. Overall proportion of subjects meeting referral criteria ranged from 4.9% (DEGAM) to 8.3% (DGfN/DGIM). The majority of patients eligible for referral were ≥ 60 years. In subjects older than 60 years, differences were even more pronounced, and rates ranged from 9.7% (DEGAM) to 16.5% (DGfN/DGIM). Estimated population level costs varied between €1,432,440 (DEGAM) and €2,386,186 (DGfN/DGIM). From 190 patients with eGFR < 60 ml/min, 15 had a risk of end stage renal disease > 5% within the next 5 years. CONCLUSIONS: Applying different referral criteria results in different referral rates and costs. Referral rates exceed actually observed consultation rates. Criteria need to be evaluated in terms of available workforce, resources and regarding over- and underutilization of nephrology services.

The course of thyroid nodules and thyroid volume over a time period of up to 10 years: a longitudinal analysis of a population-based cohort.

OBJECTIVE: Thyroid disorders are common. Information on the long-term progression of morphologic disorders is scarce. The aim of this study was to describe the course of thyroid nodules and volume over a period of up to 10 years. DESIGN AND METHODS: Data from the population-based Study of Health in Pomerania were used for longitudinal analysis of 10 years, on average. Billing data from the Association of Statutory Health Insurance Physicians were matched to the data to exclude participants with thyroid surgery, radioiodine therapy and thyroid carcinoma. Changes in the number and size of thyroid nodules and thyroid volume were observed using ultrasound. RESULTS: A total of 1270 participants were included (53% female, median age at baseline 51 years). The proportion of subjects with at least one thyroid nodule increased from 34.9 to 47.5% after 10 years. The majority of participants had an unchanged or reduced number of nodules. About one-quarter had at least one nodule of size ≥ 1 cm. The proportion of participants with goitre increased from 35 to 37% after 10 years. Nevertheless, individual thyroid volume increased by < 1 mL (95% CI: 0.38-3.66) after adjusting for age and BMI irrespective of thyroid medication. CONCLUSION: Thyroid nodules and goitre are common. After 10 years, the number of nodules did not increase in about 70% of people. This proportion did not differ substantially when excluding people with thyroid medication. Thyroid volume increased slightly over the follow-up period. These changes do not seem clinically relevant. Our results support a more restrictive approach regarding follow-up diagnostics in asymptomatic patients with thyroid nodules or minimally enlarged thyroid.

European* clinical practice recommendations on opioids for chronic noncancer pain - Part 1: Role of opioids in the management of chronic noncancer pain.

BACKGROUND: Opioid use for chronic non-cancer pain (CNCP) is complex. In the absence of pan-European guidance on this issue, a position paper was commissioned by the European Pain Federation (EFIC). METHODS: The clinical practice recommendations were developed by eight scientific societies and one patient self-help organization under the coordination of EFIC. A systematic literature search in MEDLINE (up until January 2020) was performed. Two categories of guidance are given: Evidence-based recommendations (supported by evidence from systematic reviews of randomized controlled trials or of observational studies) and Good Clinical Practice (GCP) statements (supported either by indirect evidence or by case-series, case-control studies and clinical experience). The GRADE system was applied to move from evidence to recommendations. The recommendations and GCP statements were developed by a multiprofessional task force (including nursing, service users, physicians, physiotherapy and psychology) and formal multistep procedures to reach a set of consensus recommendations. The clinical practice recommendations were reviewed by five external reviewers from North America and Europe and were also posted for public comment. RESULTS: The key clinical practice recommendations suggest: (a) first optimizing established non-pharmacological treatments and non-opioid analgesics and (b) considering opioid treatment if established non-pharmacological treatments or non-opioid analgesics are not effective and/or not tolerated and/or contraindicated. Evidence- and clinical consensus-based potential indications and contraindications for opioid treatment are presented. Eighteen GCP recommendations give guidance regarding clinical evaluation, as well as opioid treatment assessment, monitoring, continuation and discontinuation. CONCLUSIONS: Opioids remain a treatment option for some selected patients with CNCP under careful surveillance. SIGNIFICANCE: In chronic pain, opioids are neither a universal cure nor a universally dangerous weapon. They should only be used for some selected chronic noncancer pain syndromes if established non-pharmacological and pharmacological treatment options have failed in supervised pain patients as part of a comprehensive, multi-modal, multi-disciplinary approach to treatment. In this context alone, opioid therapy can be a useful tool in achieving and maintaining an optimal level of pain control in some patients.

European clinical practice recommendations on opioids for chronic noncancer pain - Part 2: Special situations.

BACKGROUND: Opioid use for chronic non-cancer pain (CNCP) is under debate. In the absence of pan-European guidance on this issue, a position paper was commissioned by the European Pain Federation (EFIC). METHODS: The clinical practice recommendations were developed by eight scientific societies and one patient self-help organization under the coordination of EFIC. A systematic literature search in MEDLINE (up until January 2020) was performed. Two categories of guidance are given: Evidence-based recommendations (supported by evidence from systematic reviews of randomized controlled trials or of observational studies) and Good Clinical Practice (GCP) statements (supported either by indirect evidence or by case-series, case-control studies and clinical experience). The GRADE system was applied to move from evidence to recommendations. The recommendations and GCP statements were developed by a multiprofessional task force (including nursing, service users, physicians, physiotherapy and psychology) and formal multistep procedures to reach a set of consensus recommendations. The clinical practice recommendations were reviewed by five external reviewers from North America and Europe and were also posted for public comment. RESULTS: The European Clinical Practice Recommendations give guidance for combination with other medications, the management of frequent (e.g. nausea, constipation) and rare (e.g. hyperalgesia) side effects, for special clinical populations (e.g. children and adolescents, pregnancy) and for special situations (e.g. liver cirrhosis). CONCLUSION: If a trial with opioids for chronic noncancer pain is conducted, detailed knowledge and experience are needed to adapt the opioid treatment to a special patient group and/or clinical situation and to manage side effects effectively. SIGNIFICANCE: If a trial with opioids for chronic noncancer pain is conducted, detailed knowledge and experience are needed to adapt the opioid treatment to a special patient group and/or clinical situation and to manage side effects effectively. A collaboration of medical specialties and of all health care professionals is needed for some special populations and clinical situations.

[Patient safety in the treatment of rheumatic diseases : Laboratory monitoring in methotrexate treatment]. / Patientensicherheit in der Rheumatherapie : Labormonitoring bei Methotrexat.

BACKGROUND: Methotrexate (MTX) is the most commonly prescribed disease-modifying drug in the treatment of rheumatic diseases. Regular laboratory testing is recommended to recognize side effects, such as hepatotoxicity and myelotoxicity as well as decreases in renal function that may cause toxic MTX accumulation. Additionally, folic acid is recommended as prophylaxis against specific side effects. In this study we investigated whether laboratory monitoring and prescription of folic acid took place according to published recommendations. MATERIAL AND METHODS: Claims data from the statutory health insurance from 1 January 2009 to 31 December 2013 were retrospectively analyzed. A total of 40,087 adults with a rheumatic diagnosis (ICD10 codes M05-M18), no malignant disease and no previous MTX prescription within 12 months were extracted from the InGef (Institute for Applied Health Research in Berlin, formerly Health Risk Institute) research database. The frequency of recommended laboratory testing, appointments with rheumatologists and the prescription of folic acid prophylaxis were investigated. RESULTS: Of the patients 12,451 began treatment with MTX in the observation period. Between 42% and 46% of recommended blood counts, liver values and kidney function tests and 14% of urinalyses were performed according to recommendations. Of the patients 84% were seen regularly by a rheumatologist and 74% received a prescription for prophylactic folic acid. Serious conditions potentially resulting from MTX treatment were observed in 0.7-3.5 cases/1000 person years. DISCUSSION: Laboratory monitoring in the context of MTX treatment is carried out less frequently than recommended in the literature. Potential MTX-associated serious complications are rare from a practice perspective. On the one hand solutions are needed for a better coordination of laboratory monitoring. On the other hand more empirical evidence is needed regarding the benefits of laboratory monitoring and the appropriate intervals thereof.

The effects of incidental findings from whole-body MRI on the frequency of biopsies and detected malignancies or benign conditions in a general population cohort study.

Magnetic resonance imaging (MRI) yields numerous tumor-related incidental findings (IFs) which may trigger diagnostics such as biopsies. To clarify these effects, we studied how whole-body MRI IF disclosure in a population-based cohort affected biopsy frequency and the detection of malignancies. Laboratory disclosures were also assessed. Data from 6753 participants in the Study of Health in Pomerania (SHIP) examined between 2008 and 2012 were utilized. All underwent laboratory examinations and 3371 (49.9%) a whole-body MRI. Electronic biopsy reports from 2002 to 2017 were linked to participants and assigned to outcome categories. Biopsy frequency 2 years pre- and post-SHIP was investigated using generalized estimating equations with a negative-binomial distribution. Overall 8208 IFs (laboratory findings outside reference limits: 6839; MRI: 1369) were disclosed to 4707 participants; 2271 biopsy reports belonged to 1200 participants (17.8%). Of these, 938 biopsies occurred pre-SHIP; 1333 post-SHIP (event rate/100 observation years = 6.9 [95% CI 6.5; 7.4]; 9.9 [9.3; 10.4]). Age, cancer history, recent hospitalization, female sex, and IF disclosure were associated with higher biopsy rates. Nonmalignant biopsy results increased more in participants with disclosures (post-/pre-SHIP rate ratio 1.39 [95% CI 1.22; 1.58]) than without (1.09 [95% CI 0.85; 1.38]). Malignant biopsy results were more frequent post-SHIP (rate ratio 1.74 [95% CI 1.27; 2.42]). Biopsies increased after participation in a population-based cohort study with MRI and laboratory IF disclosure. Most biopsies resulted in no findings and few malignancies were diagnosed, indicating potential overtesting and overdiagnosis. A more restrictive policy regarding IF disclosure from research findings is required.

Recall accuracy of notifications about incidental findings from an MRI examination: results from a population-based study.

BACKGROUND: Self-reports of medical findings are indispensable in clinical practice and research but subject to recall bias. We analysed the recall accuracy of notifications about incidental findings (IFs) from a whole-body MRI examination and assessed determinants of recall error. METHODS: Data from 3746 participants of a postal follow-up survey conducted on average 2.47 years after examination in the population-based Study of Health in Pomerania were analysed. Among those, 2185 (58.3%) underwent whole-body MRI at baseline, and findings of potential clinical relevance were disclosed in standardised postal letters. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were calculated to determine the accuracy of self-reports. Poisson regression analysis was conducted to analyse predictors for false-positive and false-negative recall. RESULTS: An IF was disclosed to 622 (28.5%) individuals; 81.5% had tumour relevance. The overall sensitivity and PPV of participants' self-reports were 80% and 60%, respectively. PPvs were higher among women, better educated and married participants and among those with good verbal memory. Among MRI participants, lower educational level was associated with a higher risk of false-positive recall (risk ratio (RR) 1.44, 95% CI 1.01 to 2.03), while increasing age was associated with a higher risk of false-negative recall (RR 1.64, 95% CI 1.33 to 2.01). CONCLUSIONS: Most participants correctly recalled disclosed IFs. However, the probability of an event in case of a positive recall is barely above 50%. Therefore, relying on subjects' recall of disclosed IFs will lead to a relevant proportion of errors. Clinicians and researchers should be aware of this problem and of participants' characteristics which may moderate the probability of correct decisions based on recalled findings.

[Effect of ambulatory geriatric rehabilitation on polypharmacy and potentially inappropriate medication-an observational study]. / Effekt der ambulanten geriatrischen Komplexbehandlung auf Polypharmazie und potenziell inadäquate Arzneimittel ­ eine Beobachtungsstudie.

BACKGROUND: Ambulatory geriatric rehabilitation (AGR) is a prevention program for multimorbid patients with the contractual agreement to prevent the need for care and hospital admissions and to promote self-sufficiency. It provides an opportunity to reduce the prevalence of polypharmacy and to discontinue potentially inadequate medication (PIM). AIM: The study investigated the effect of AGR on the number of drugs and PIM. MATERIAL AND METHODS: The observational longitudinal study was based on claims data from the statutory health insurance AOK Nordost. A comparison of the prescribed drugs with the PRISCUS list was performed. The study investigated the effect of AGR on the number of drugs prescribed and PIM in the period of two quarterly periods before and two quarterly periods after AGR. The numbers of prescribed statins, opioids, antidementia drugs, proton pump inhibitors and antidepressants were assessed and grouped into further prescriptions, new prescriptions and discontinued drug prescriptions. RESULTS: Out of 699 participants 682 (73% women, mean age 79 years, SD ± 5 years) were analyzed. The number of substances and PIM remained at the same levels after AGR. Psycholeptic, antiphlogistic and psychoanaleptic drugs were the most frequently prescribed PIM. The majority of statins, opioids, antidementia drugs, proton pump inhibitors and antidepressants were prescribed further. Antidementia drugs were the medication with the most newly started prescriptions. CONCLUSION: The AGR has no influence on the number of prescribed drugs and PIM. A structured drug review and a conversation with the general practitioner should be strengthened to improve drug safety and reduce polypharmacy as well as undertreatment.

The association of intensive care with utilization and costs of outpatient healthcare services and quality of life.

BACKGROUND: Little is known about outpatient health services use following critical illness and intensive care. We examined the association of intensive care with outpatient consultations and quality of life in a population-based sample. METHODS: Cross-sectional analysis of data from 6,686 participants of the Study of Health in Pomerania (SHIP), which consists of two independent population-based cohorts. Statistical modeling was done using Poisson regression, negative binomial and generalized linear models for consultations, and a fractional response model for quality of life (EQ-5D-3L index value), with results expressed as prevalence ratios (PR) or percent change (PC). Entropy balancing was used to adjust for observed confounding. RESULTS: ICU treatment in the previous year was reported by 139 of 6,686 (2,1%) participants, and was associated with a higher probability (PR 1.05 [CI:1.03;1.07]), number (PC +58.0% [CI:22.8;103.2]) and costs (PC +64.1% [CI:32.0;103.9]) of annual outpatient consultations, as well as with a higher number of medications (PC +37.8% [CI:17.7;61.5]). Participants with ICU treatment were more likely to visit a specialist (PR 1.13 [CI:1.09; 1.16]), specifically internal medicine (PR 1.67 [CI:1.45;1.92]), surgery (PR 2.42 [CI:1.92;3.05]), psychiatry (PR 2.25 [CI:1.30;3.90]), and orthopedics (PR 1.54 [CI:1.11;2.14]). There was no significant effect regarding general practitioner consultations. ICU treatment was also associated with lower health-related quality of life (EQ-5D index value: PC -13.7% [CI:-27.0;-0.3]). Furthermore, quality of life was inversely associated with outpatient consultations in the previous month, more so for participants with ICU treatment. CONCLUSIONS: Our findings suggest that ICU treatment is associated with an increased utilization of outpatient specialist services, higher medication intake, and impaired quality of life.

Proactive multipurpose health risk screening in health care settings: Methods, design, and reach.

OBJECTIVES: Real world implementation of proactive screening and brief intervention in health care is threatened by high cost. Using e-health interventions and screening for multiple health risk factors may provide more efficiency. We describe methodological details of a proactive multipurpose health risk screening in health care settings and report on participation rates, participants' characteristics, and participation factors. METHODS: Patients between 18 and 64 years from ambulatory practices and hospitals were proactively approached by study assistants at three sites for a computerized screening on harmful alcohol and tobacco consumption, depressive symptoms, insufficient fruit/vegetable consumption, physical inactivity and overweight. On the basis of their health risk pattern, a computerized algorithm allocated patients to one of five studies each of them addressing a psychiatric research question. RESULTS: Among all eligible patients, 13,763 (86.5%) were screened. Younger age and being female predicted screening participation. Of those with complete data (n = 12,828), 82.9% reported at least two health risks and 34.0% were eligible for a study. Study participation ranged between 35.2% and 50.8%, and was associated with socio-demographics and problem severity. CONCLUSIONS: This study supports the use of systematic proactive screening for multiple health risks in health care settings as it is more resource-saving than single focused screening.

[Prevalence of Cardiovascular Risk Factors at The Population Level: A Comparison of Ambulatory Physician-Coded Claims Data With Clinical Data From A Population-Based Study]. / Untersuchung der Prävalenz kardiologischer Risikofaktoren in der Allgemeinbevölkerung: Ein Vergleich ambulanter ärztlicher Abrechnungsdaten mit Daten einer populationsbasierten Studie.

OBJECTIVE: The study assesses the validity of ICD-10 coded cardiovascular risk factors in claims data using gold-standard measurements from a population-based study for arterial hypertension, diabetes, dyslipidemia, smoking and obesity as a reference. METHODS: Data of 1941 participants (46 % male, mean age 58±13 years) of the Study of Health in Pomerania (SHIP) were linked to electronic medical records from the regional association of statutory health insurance physicians from 2008 to 2012 used for billing purposes. Clinical data from SHIP was used as a gold standard to assess the agreement with claims data for ICD-10 codes I10.- (arterial hypertension), E10.- to E14.- (diabetes mellitus), E78.- (dyslipidemia), F17.- (smoking) and E65.- to E68.- (obesity). RESULTS: A higher agreement between ICD-coded and clinical diagnosis was found for diabetes (sensitivity (sens) 84%, specificity (spec) 95%, positive predictive value (ppv) 80%) and hypertension (sens 72%, spec 93%, ppv 97%) and a low level of agreement for smoking (sens 18%, spec 99%, ppv 89%), obesity (sens 22%, spec 99%, ppv 99%) and dyslipidemia (sens 40%, spec 60%, ppv 70%). Depending on the investigated cardiovascular risk factor, medication, documented additional cardiovascular co-morbidities, age, sex and clinical severity were associated with the ICD-coded cardiovascular risk factor. CONCLUSION: The quality of ICD-coding in ambulatory care is highly variable for different cardiovascular risk factors and outcomes. Diagnoses were generally undercoded, but those relevant for billing were coded more frequently. Our results can be used to quantify errors in population-based estimates of prevalence based on claims data for the investigated cardiovascular risk factors.

[Local Allergic Reaction to Subcutaneous Treatment with Procaine in a Patient with Shoulder Pain - a Case Study]. / Lokale allergische Reaktion nach subkutaner Applikation von Procain bei einem Patienten mit Schulterschmerzen ­ Fallbericht.

HISTORY: A 53-year-old man presented at the general practitioner's office with 2 weeks of existing shoulder pain without radiation. On physical examination, no abnormalities were found, except for left-sided tension of the shoulder muscles. FINDINGS AND DIAGNOSIS: Because of the expected self-limiting nature of the complaints, no further tests were conducted. Based on shoulder pain with local muscle tension, the working diagnosis cervicobrachialgia was adopted. THERAPY AND COURSE: The pain was treated with local subcutaneous administration of procaine. 4 days later, the patient presented with distinct patches of urticaria at the injection sites, which regressed spontaneously over the course of 2 weeks. DISCUSSION: Allergic reactions occuring after treatment with procaine are rare, but can be life-threatening if systemic or afflicting vital structures.Patients should be informed about the importance of the allergy in relation to medical procedures, such as dental treatment, and about cross-reactivity with other medication.

[Drug Prescribing for Patients with Chronic Kidney Disease in General Practice: a Cross-Sectional Study]. / Arzneimittelverordnung bei Patienten mit chronischer Niereninsuffizienz in der hausärztlichen Versorgung.

BACKGROUND: Many drugs require dose adjustment or are contraindicated in patients with chronic kidney disease (CKD) to avoid adverse events. The aims of this study were to assess if medication was appropriately dose adjusted in patients with CKD in primary care, to identify medications that were frequently prescribed inappropriately and to identify factors predicting mal-prescription. METHODS: We conducted a cross-sectional observational study in 34 general practioners' offices, assessing the medication of patients with CKD stage ≥ 3 according to the corresponding pharmaceutical product information. Additional information was extracted from recommendations of scientific societies and regulatory authorities. Contraindicated and overdosed medications were identified. Predictive factors for inadequate prescribing were analyzed with multiple logistic regression. RESULTS: 589 patients (Ø 78 years, 63 % female) with CKD stage ≥ 3 were included. A total of 5102 medications were extracted from the medication sheets (94,6 % regular, 5,4 % "as needed"). 4,2 % were judged as being inadequate according to pharmaceutical information (2,1 % contraindicated, 2,1 % overdosed). 173 patients (29 %) had ≥ 1 inadequate prescription. The proportion of inadequate prescriptions fell to 3,5 % after adjustment for the most recent recommendations of scientific societies and regulatory authorities. Most frequent inappropriate prescriptions were ACE-inhibitors, diuretics, oral antidiabetic drugs, methotrexate and potassium supplements. Most important predictors for inadequate prescriptions were CKD stage ≥ 3b and number of medications. CONCLUSION: A quarter of all patients had a least one inadequate prescription. The overall proportion of inadequately prescribed drugs was low. Adjustment for recommendations by scientific societies and regulatory authorities further reduced the number of inadequate prescriptions. Valid data on the clinical relevance of inadequate prescriptions is scarce and further research is required. Because of the time and effort needed to assess all medications, future quality improvement projects should focus on CKD stage ≥ 3b, patients with polypharmacy and crucial medication.

Comparison of traditional diabetes risk scores and HbA1c to predict type 2 diabetes mellitus in a population based cohort study.

AIMS: Compare performances of diabetes risk scores and glycated hemoglobin (HbA1c) to estimate the risk of incident type 2 diabetes mellitus (T2DM) in Northeast Germany. METHODS: We studied 2916 subjects (20 to 81years) from the Study of Health in Pomerania (SHIP) in a 5-year follow-up period. Diabetes risk scores included the Cooperative Health Research in the Region of Augsburg (KORA) base model, the Danish diabetes risk score and the Data from the Epidemiological Study on the Insulin Resistance syndrome (D.E.S.I.R) clinical risk score. We assessed the performance of each of the diabetes risk scores and the HbA1c for 5-year risk of T2DM by the area under the receiver-operating characteristic curve (AUC) and calibration plots. RESULTS: In SHIP, the incidence of T2DM was 5.4% (n=157) in the 5-year follow-up period. Diabetes risk scores and HbA1c achieved AUCs ranging from 0.76 for the D.E.S.I.R. clinical risk score to 0.82 for the KORA base model. For diabetes risk scores, the discriminative ability was lower for the age group 55 to 74years. For HbA1c, the discriminative ability also decreased for the group 55 to 74years while it was stable in the age group 30 to 64years old. CONCLUSIONS: All diabetes risk scores and the HbA1c showed a good prediction for the risk of T2DM in SHIP. Which model or biomarker should be used is driven by its context of use, e.g. the practicability, implementation of interventions and availability of measurement.

[Management of Patients with CKD in Clinical Practice]. / Chronische Nierenerkrankungen ­ was der Praktiker wissen sollte.

Chronic kidney disease (CKD) affects between 3 and 17 % of the population in Europe, especially elderly persons. CKD is a clinical syndrome which may develop in patients with e. g. diabetes mellitus, arterial hypertension or autoimmune diseases. A poorer renal function - especially in old age - is to be considered irrespective of the medication. Many antibiotics and painkillers require dose adjustments. Therapy should be done in a manner which is suitable for indication. Polypharmacy should be avoided as far as possible. Diuretics and RAAS inhibitors are useful drugs in therapy of CKD. Changes of lifestyle are important, so as weight reduction, restriction of salt and fructose, sufficient drinking, strict control of blood glucose, blood pressure and hypercholesterolaemia. Additional acute lesions have to be avoided ("acute-on-chronic renal failure").

Oral Health and nutritional status in nursing home residents-results of an explorative cross-sectional pilot study.

BACKGROUND: This study was performed to assess oral and nutritional status of nursing home residents in a region of Lower Saxony, Germany. The aim was to show potential associations between oral status (dentate or edentulous), further anamnestic factors (dementia, age, smoking) and the risk for malnutrition in this population. METHODS: In this observational cross-sectional pilot study of residents from four nursing homes Mini Nutritional Assessment (MNA), Body-Mass-Index (BMI), dental status (DMF-T) and periodontal situation (PSR®/PSI) were recorded. Associations of recorded factors with oral health and nutritional status were examined in univariate and multivariate analysis. RESULTS: Eighty-seven residents participated in the study (mean age: 84.1 years; female: 72%, demented: 47%). Average BMI was 26.2 kg/m2; according MNA 52% were at risk for malnutrition. 48% of the residents were edentulous, and the average DMF-T of dentulous was 25.0 (3.7) (D-T: 2.0 [3.1], M-T: 15.0 [8.3], F-T: 8.0 [7.4]); PSR®/PSI 3 and 4 (need for periodontal treatment) showed 79% of residents. In univariate analysis dementia (OR 2.5 CI95 1.1-5.6) but not being edentulous (OR 2.0 CI95 0.8-5.8) were associated with being at risk for malnutrition. Dementia remained associated in multivariate analysis adjusting for age and sex, (OR 3.1 CI95 1.2-8.2) and additionally being edentulous (OR 2.8 CI95 1.1-7.3) became associated significantly. Furthermore, nursing home residents with dementia had more remaining teeth (OR 2.5 CI95 1.1-5.9). CONCLUSION: Dementia was a stronger predictor for risk of malnutrition in nursing home residents than being edentulous. Further studies to elucidate the possible role of oral health as cofactor for malnutrition in dementia are needed.

[Cancer screening in the elderly: Explorative mixed methods study]. / Krebsfrüherkennungsuntersuchungen im hohen Alter: Explorative "Mixed-methods"-Studie.

BACKGROUND: The benefits of cancer screening in the elderly are uncertain. While the risk of cancer increases with age the participation in cancer screening decreases. AIM: The study investigated the attitudes of older adults towards cancer screening as well as their motives for or against participation. MATERIAL AND METHODS: This population-based explorative mixed methods study was based on a survey of residents aged 69-89 years from the district of Western Pomerania-Greifswald (northeast Germany). Criteria for exclusion were cognitive deficits and/or cancer. Attitudes towards different statements regarding cancer screening were assessed by a questionnaire using 5-point Likert scales. Semi-structured interviews were used to explore the motivations. RESULTS: Out of 630 contacted residents, 120 (19%) with an average age of 77 years (SD ± 6 years) participated in the face-to-face survey. The majority were in favor of lifelong cancer screening, 14% stated other health problems to be more important than cancer screening and 7% assumed that they would not live long enough to benefit from screening.
