Extravertebral low back pain: a scoping review.

BACKGROUND: Low back pain (LBP) is one of the most common reasons for consultation in general practice. Currently, LBP is categorised into specific and non-specific causes. However, extravertebral causes, such as abdominal aortic aneurysm or pancreatitis, are not being considered. METHODS: A systematic literature search was performed across MEDLINE, Embase, and the Cochrane library, complemented by a handsearch. Studies conducted between 1 January 2001 and 31 December 2020, where LBP was the main symptom, were included. RESULTS: The literature search identified 6040 studies, from which duplicates were removed, leaving 4105 studies for title and abstract screening. Subsequently, 265 publications were selected for inclusion, with an additional 197 publications identified through the handsearch. The majority of the studies were case reports and case series, predominantly originating from specialised care settings. A clear distinction between vertebral or rare causes of LBP was not always possible. A range of diseases were identified as potential extravertebral causes of LBP, encompassing gynaecological, urological, vascular, systemic, and gastrointestinal diseases. Notably, guidelines exhibited inconsistencies in addressing extravertebral causes. DISCUSSION: Prior to this review, there has been no systematic investigation into extravertebral causes of LBP. Although these causes are rare, the absence of robust and reliable epidemiological data hinders a comprehensive understanding, as well as the lack of standardised protocols, which contributes to a lack of accurate description of indicative symptoms. While there are certain disease-specific characteristics, such as non-mechanical or cyclical LBP, and atypical accompanying symptoms like fever, abdominal pain, or leg swelling, that may suggest extravertebral causes, it is important to recognise that these features are not universally present in every patient. CONCLUSION: The differential diagnosis of extravertebral LBP is extensive with relatively low prevalence rates dependent on the clinical setting. Clinicians should maintain a high index of suspicion for extravertebral aetiologies, especially in patients presenting with atypical accompanying symptoms.

The Preventiometer - reliability of a cardiovascular multi-device measurement platform and its measurement agreement with a cohort study.

BACKGROUND: Multimedia multi-device measurement platforms may make the assessment of prevention-related medical variables with a focus on cardiovascular outcomes more attractive and time-efficient. The aim of the studies was to evaluate the reliability (Study 1) and the measurement agreement with a cohort study (Study 2) of selected measures of such a device, the Preventiometer. METHODS: In Study 1 (N = 75), we conducted repeated measurements in two Preventiometers for four examinations (blood pressure measurement, pulse oximetry, body fat measurement, and spirometry) to analyze their agreement and derive (retest-)reliability estimates. In Study 2 (N = 150), we compared somatometry, blood pressure, pulse oximetry, body fat, and spirometry measurements in the Preventiometer with corresponding measurements used in the population-based Study of Health in Pomerania (SHIP) to evaluate measurement agreement. RESULTS: Intraclass correlations coefficients (ICCs) ranged from .84 to .99 for all examinations in Study 1. Whereas bias was not an issue for most examinations in Study 2, limits of agreement for most examinations were very large compared to results of similar method comparison studies. CONCLUSION: We observed a high retest-reliability of the assessed clinical examinations in the Preventiometer. Some disagreements between Preventiometer and SHIP examinations can be attributed to procedural differences in the examinations. Methodological and technical improvements are recommended before using the Preventiometer in population-based research.

Effect evaluation of a tele-neurologic intervention in primary care in a rural area in Germany-the NeTKoH study protocol of a stepped-wedge cluster randomized trial.

BACKGROUND: Neurological disorders account for a large and increasing proportion of the global burden of disease. Therefore, it is important to strengthen the management of neurologic care, particularly in rural areas. The use of tele-neurology in primary care in rural areas is internationally considered to have the potential to increase access to health care services and improve the quality of care in these underserved areas. NeTKoH aims to address the existing knowledge gap regarding the effects of a tele-neurologic intervention in primary care under real-world conditions in a rural area in Germany. METHODS: NeTKoH is a cluster-randomized controlled trial with a stepped-wedge design involving 33 outpatient general practitioner's (GP) offices (clusters) in a rural area in Northeast Germany. During 11 predetermined steps, all clusters are randomized before they cross over into groups from the control to the intervention arm. The targeted sample size is 1,089 patients with neurologic symptoms that are continuously being recruited. In the intervention arm, tele-neurologic consultations will be provided via a face-to-face video conferencing system with a neurologic expert at a university hospital. The control arm will receive usual care. The primary outcome is the proportion of neurologic problems being solved at the GP's office. Secondary outcomes will comprise hospital stays and days, time until neurologic specialist appointments and diagnostics, patients' health status and quality of life, outpatient and inpatient referrals. A concurrent observational study, together with a process, implementation, and health economic evaluation, will also be conducted. DISCUSSION: Using a stepped-wedge cluster design in a real-life situation can help with logistic challenges and enhance the motivation of the participating GPs, as all, at some point, will be in the intervention phase. With the additional implementation evaluation pertaining to external validity, an observational study, and a health economic evaluation, NeTKoH will be able to provide an extensive evaluation for health policy decision-makers regarding the uptake into standard care.

[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.

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.

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).

Ivy leaf (Hedera helix) for acute upper respiratory tract infections: an updated systematic review.

PURPOSE: Acute cough due to viral upper respiratory tract infections (URTIs) and bronchitis is a common reason for patients to seek medical care. Non-antibiotic over-the-counter cough medications such as ivy leaf extract are frequently used but their efficacy is uncertain. Our purpose was to update our previous systematic review and evaluate the effectiveness and tolerability of ivy leaf in the treatment of acute URTIs in adult and pediatric populations. METHODS: We searched MEDLINE, EMBASE, the Cochrane Library, and clinical trial registries from December 2009 to January 2020. Randomized controlled trials (RCTs), controlled clinical trials (CCTs), and observational studies (OSs) investigating ivy leaf mono- or combination preparations were included. Two independent reviewers assessed records for eligibility and risk of bias and performed data extraction. RESULTS: Six RCTs, 1 CCT, and 4 OSs were identified. Since the publication of our previous review, the number of RCTs has increased. All studies concluded that ivy leaf extract is an effective and safe option for the treatment of cough due to URTIs and bronchitis. Three RCTs reported a more rapid reduction in cough severity and/or frequency under ivy leaf treatment. The clinical significance of these effects appears to be minimal. No serious adverse effects were reported. The overall quality of reporting was low and the risk of bias was high. CONCLUSIONS: Ivy leaf preparations are safe for use in cough due to acute URTIs and bronchitis. However, effects are minimal at best and of uncertain clinical importance.

Lack of association between proton pump inhibitor use and brain aging: a cross-sectional study.

PURPOSE: Due to conflicting scientific evidence for an increased risk of dementia by intake of proton pump inhibitors (PPIs), this study investigates associations between PPI use and brain volumes, estimated brain age, and cognitive function in the general population. METHODS: Two surveys of the population-based Study of Health in Pomerania (SHIP) conducted in Northeast Germany were used. In total, 2653 participants underwent brain magnetic resonance imaging (MRI) and were included in the primary analysis. They were divided into two groups according to their PPI intake and compared with regard to their brain volumes (gray matter, white matter, total brain, and hippocampus) and estimated brain age. Multiple regression was used to adjust for confounding factors. Cognitive function was evaluated by the Verbal Learning and Memory Test (VLMT) and the Nuremberg Age Inventory (NAI) and put in relation to PPI use. RESULTS: No association was found between PPI use and brain volumes or the estimated brain age. The VLMT score was 1.11 lower (95% confidence interval: - 2.06 to - 0.16) in immediate recall, and 0.72 lower (95% CI: - 1.22 to - 0.22) in delayed recall in PPI users than in non-users. PPI use was unrelated to the NAI score. CONCLUSIONS: The present study does not support a relationship between PPI use and brain aging.

[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.

Dual renin-angiotensin-aldosterone blockade: Implementation of published research and Dear Doctor letters in ambulatory care: A retrospective observational study using prescription data.

PURPOSE: This study aims to assess the implementation of published research, contraindications, and warnings on the prescription of dual renin-angiotensin-hormone system (RAS) blockade in ambulatory care in Germany. METHODS: Cohort study based on health claims data of 6.7 million subjects from 2008 to 2015. Yearly prevalence and incidence for dual RAS blockade with (a) angiotensin-converting enzyme inhibitors and angiotensin-receptor blockers (ACEI + ARB) and (b) aliskiren and ACEI or ARB (aliskiren + ACEI/ARB) were calculated. We assessed prescriber specialty and associations between discontinuing dual RAS blockade with specialist (internal medicine, cardiology, nephrology) visits and hospital discharge in the previous year. RESULTS: A total of 2 984 517 patients were included (age 51.4 ± SD 18.4 y, 48.5% male). Prescription rates for ACEI + ARB decreased from 0.6% (n = 17 907) to 0.4% (n = 12 237) and for aliskiren + ACEI/ARB from 0.23% (n = 6634) to 0.03% (n = 818). Incident prescriptions decreased from 0.23% (n = 6705) to 0.19% (n = 5055) (ACE + ARB) and from 0.1% (n = 2796) to 0.005% (n = 142) (aliskiren + ACE/ARB); 59% of ACEI + ARB and 48% of aliskiren + ACE/ARB combinations were prescribed only by one physician. Of those, 73% (ACEI + ARB) and 58% (aliskiren + ACE/ARB) were primary care providers (PCPs). Discontinuing dual RAS blockade was associated with specialist care and hospital discharge in the previous year (specialist care: RR 1.4, 95% CI, 1.3-1.6; hospital visit: RR 1.5, 95% CI, 1.3-1.6). CONCLUSIONS: Our results suggest a delayed uptake of treatment recommendation for ACEI + ARB and a higher impact of Dear Doctor letters addressing PCPs directly compared with published research, contraindications, and warnings. Targeted continuous medical education, practice software alerts, and stronger involvement of pharmacists might improve the implementation of medication safety recommendations in ambulatory care.

Evaluation of an ambulatory geriatric rehabilitation program - results of a matched cohort study based on claims data.

BACKGROUND: Ambulatory geriatric rehabilitation (AGR) is a multidisciplinary outpatient prevention program designed to decrease hospitalisation and dependence on nursing care in multimorbid patients ≥70 years of age. We evaluated the effectiveness of AGR compared to usual care on progression of nursing care levels, nursing home admissions, hospital admissions, incident fractures, mortality rate and total cost of care during a one-year follow-up period. METHODS: Analyses were based on claims data from the health insurance company AOK Nordost. Propensity Score matching was used to match 4 controls to each person receiving the AGR intervention. RESULTS: A total of 632 AGR participants and 2528 matched controls were included. The standardized mean difference of matching variables between cases and controls was small (mean: + 1.4%; range: - 4.4/3.9%). In AGR patients, the progression of nursing care levels (+ 2.2%, 95%CI: - 0.9 /5.3), nursing home admissions (+ 1.7%, 95%CI: - 0.1/3.5), hospital admissions (+ 1.1%, 95%CI: - 3.2/5.4), incident fractures (+ 11.1%, 95%CI: 7.3/15) and mortality rate (+ 1.2%, p = 0.20) showed a less favourable course compared to controls. The average total cost per AGR participant was lower than in the control group (- 353€, 95%CI: - 989€/282€), not including costs for AGR. CONCLUSIONS: Analysis based on claims data showed no clinical benefit from AGR intervention regarding the investigated outcomes. The slightly worse outcomes may reflect limitations in matching based on claims data, which may have insufficiently reflected morbidity and psychosocial factors. It is possible that the intervention group had poorer health status at baseline compared to the control group.

Frequency of thyroid function tests and examinations in participants of a population-based study.

BACKGROUND: Thyroid disorders are common in the adult German population. Little is known about guideline implementation in clinical practice and the prevalence of diagnostic procedures in ambulatory care. The study aims to investigate the use of thyroid hormone measurements, thyroid ultrasound, thyroid scintiscan and associated costs in ambulatory care at population level. METHODS: Data were derived from two independent population-based cohorts of the Study of Health In Pomerania (SHIP). Ambulatory billing data from the Association of Statutory Health Insurance Physicians Mecklenburg-Vorpommern were individually linked for the period 2002-2016 with SHIP data. The main outcomes were the frequency of outpatient ultrasound, scintiscan, serum TSH level measurement, free triiodothyronine (fT3) and free thyroxine (fT4) measurement, TSH-receptor-antibodies and microsomal antibodies measurement within 1 year and 3 years prior to the study entrance of the participants. Multinomial logistic regression models were used to assess the association of age, sex, thyroid medication intake and Charlson-Comorbidity-Index with frequency of TSH measurements and ultrasound examinations. RESULTS: A total of 5552 participants (47% male, median age 55) were included in the analysis. 25% (1409/5552) had a diagnosed thyroid disorder or treatment, 40% (2191/5552) had clinical findings based on ultrasound or laboratory testing in SHIP only and 35% (1952/5552) neither a coded thyroid disorder or clinical finding nor thyroid medication. In the total study population 30% (1626/5552) received at least one TSH measurement, 6.8% (378/5552) at least one thyroid ultrasound and 2.6% (146/5552) at least one scintiscan within the past year before the study examination. Tests were performed more frequently in patients with thyroid medication and coded thyroid disorders. Hence, this group caused the highest expenditures. CONCLUSIONS: Given the high prevalence of thyroid disorders, diagnostic and monitoring tests should be used rationally with regard to costs. TSH levels should be monitored regularly in patients on thyroid medication. A consensus on monitoring frequency and iteration of monitoring of morphological thyroid disorders with TSH and ultrasound and specific guideline recommendations are needed.

Concordance of patient beliefs and expectations regarding the management of low back pain with guideline recommendations - a cross-sectional study in Germany.

BACKGROUND: Low back pain is a common reason for patients to seek medical care. Physician non-adherence to clinical guidelines has been observed. We investigated the extent to which patient expectations correspond to recommendations of the German national guideline for management of low back pain (G-LBP) and whether patient characteristics, history of LBP and previous treatment experience are associated with expectations. METHODS: A cross-sectional study including patients from 13 general practices was conducted. Data were collected using a questionnaire. Inverse probability weights were used to address non-response bias. Descriptive analysis and multivariate logistic regression models were performed. RESULTS: A total of 977 patients were included in analyses (median age 57 years, 39% male). 75% of patients reported experiencing LBP currently or within the last year. More than 65% indicated they would agree to forgo further examinations if their LBP was judged by their physician to be of no serious concern. This was associated with the highest level of education and no prior imaging, and negatively associated with good-to-poor health status and moderate-to-severe pain intensity. 40% of participants expected imaging. The highest educational level, female gender and no prior imaging were associated with a decreased expectation of imaging. 70% expected prescriptions for massages. Females, participants with good-to-poor health status, current LBP or LBP in the last 12 months had an increased expectation for massages. Expectations for injection therapy (45%) were mainly associated with previous injections. Expectations for physiotherapy (64%) were associated with female gender, lower educational level, good-to-poor health status, current LBP or in the last 12 months. The perspective that daily activities should be continued (66%) was associated with female gender and higher educational level. Participants who agreed to the statement 'There is no effective treatment for LBP' (11%) had a poor health status, current LBP and a severe pain intensity. CONCLUSION: Patient views regarding LBP management are partially concordant with guideline recommendations and are strongly influenced by previous treatment experiences and education level. Exploration of patient expectations and experiences in LBP treatment may help minimize dissatisfaction of patients expecting treatments not endorsed by guidelines and simultaneously increase physician guideline adherence.

[Frequencies of musculoskeletal symptoms and disorders in the population-based German National Cohort (GNC)]. / Häufigkeiten muskuloskelettaler Symptome und Erkrankungen in der bevölkerungsbezogenen NAKO Gesundheitsstudie.

BACKGROUND: Musculoskeletal diseases and symptoms are very common in the general population. They lead to high healthcare costs and pose a significant burden to the national economy. OBJECTIVES: Based on data from the population-based German National Cohort (GNC), frequencies of musculoskeletal symptoms and diseases are reported, including back pain, osteoporosis, osteoarthritis, and arthritis. MATERIALS AND METHODS: Data were collected from March 2014 to March 2017 in adults aged 20-75 years during the first half of the baseline survey of the GNC. The sample comprised 101,779 interviewed subjects, including 9370 subjects who underwent clinical musculoskeletal examinations. The interview included questions about specific musculoskeletal disorders. A clinical examination of the hand provided information about palpable swollen joints and pressure-sensitive joints. Resting pain of the knees and hips was also assessed by a clinical examination. Frequencies were standardized to the German standard population of the year 2011. RESULTS: Having ever been diagnosed with recurrent back pain (22.5%) or osteoarthritis (20.6%) were the most common complaints reported in the interview; osteoporosis (2.9%) and rheumatoid arthritis (1.9%) were stated more seldom. According to the hand examination, 6.0% of all participants experienced pain in at least one finger joint. Resting pain was present in at least one knee among 8.2% and in at least one hip among 5.1% of the participants as assessed during the clinical examination. Women were more likely to report musculoskeletal disorders and symptoms than men. The proportion of adults affected by musculoskeletal diseases increased strongly with age. CONCLUSION: Musculoskeletal disorders and symptoms occur frequently. The burden of complaints and diagnoses is comparable to previous population-based surveys.

[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.

[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.

[Effectiveness of a risk-tailored short intervention to prevent chronic low back pain : A cluster-randomized study in general practice]. / Effekte einer risikoadaptierten Kurzintervention zur Prävention der Chronifizierung bei akuten Rückenschmerzen : Eine clusterrandomisierte Studie in Hausarztpraxen.

BACKGROUND: A subgroup of patients with acute low back pain (LBP) will develop chronic LBP. Risk factors summarized as yellow flags are fear-avoidance beliefs, depression, catastrophizing, and work-related problems. OBJECTIVE: The aim was to evaluate the effectiveness of screening for yellow flags in general practice followed by a risk-tailored group intervention compared to care as usual. METHODS: This is a cluster-randomized controlled trial in 35 general practices with 354 patients with acute LBP. Information or a standardized group intervention was offered to patients in the intervention group according to the screening algorithm with a short questionnaire for physical and psychosocial risk factors for chronic LBP. Standardized group information contained education concerning back pain and strategies for physical activities and planning of actions. Primary outcome was functional capacity assessed after 6 and 12 months with a questionnaire. Secondary outcomes were pain severity, fear avoidance beliefs, depression score, self-rated health and health service utilization. RESULTS: The intervention had no clinically relevant effect on the primary outcome functional capacity and secondary outcomes, although the course was consistently slightly better. Adherence to the offered intervention was low. Health service utilization was not altered to a relevant extent. A subgroup analysis comparing adherent and non-adherent patients showed a consistently better course of adherent patients. CONCLUSIONS: A risk-tailored short intervention to prevent chronic LBP in general practice had no significant impact on the clinical course compared to care as usual. A subgroup analysis comparing adherent and non-adherent patients suggests that it is possible to have a positive impact on patient-relevant outcomes.

[Course of Treatment and Sustainability of Ambulatory Geriatric Rehabilitation - An Analysis of 128 Geriatric Patients]. / Behandlungsverläufe und Nachhaltigkeit der Ambulanten Geriatrischen Komplexbehandlung ­ eine Analyse von 128 geriatrischen Patienten.

AIM OF THE STUDY: The observational study aims to investigate the course of clinical outcomes of geriatric, multimorbid patients who received ambulatory geriatric rehabilitation (AGR) for four weeks. METHODS: Analyses were based on data from 128 patients. Basic geriatric assessment tests and the EQ5D-Scale were used before, directly after the intervention, as well as after 6 and 12 months. Data were analyzed using Mixed-Effects Regression-Models. RESULTS: AGR improved self-dependence, mobility, balance, risk of falls and general state of health. The cognitive conditions reduced slightly. CONCLUSIONS: The patient-related clinical endpoints indicate a positive influence of functional deficits.

[Prevalence of thyroid abnormality: a comparison of ambulatory claims data with data from a population-based study]. / Schilddrüsenveränderungen: Ein Vergleich ambulanter Abrechnungsdaten mit Daten einer populationsbasierten Studie.

BACKGROUND: Billing diagnoses are used for quality assurance, estimates of prevalence and resource allocation. Validity studies showed relevant limitations. In Germany, there are no population-based data on the agreement of outpatient billing diagnoses with clinical data of thyroid disorders. OBJECTIVES: The study investigated the agreement of ICD-diagnosed thyroid nodules, goitre, hyperthyroidism, hypothyroidism and thyroiditis with clinical and self-reported data from the population-based cohort study called the Study of Health in Pomerania (SHIP). MATERIALS AND METHODS: Billing data from the Association of Statutory Health Insurance Physicians Mecklenburg-Vorpommern were linked on an individual level for the period from 2002-2016 with data from SHIP. The agreement was evaluated using sensitivity, specificity and positive and negative predictive value (PPW, NPW). Data were weighted to ensure population representativeness. RESULTS: The data of 5746 participants were analysed (46% male, average age 55 years, SD [standard deviation] ± 15, min: 20 years, max: 93 years). Based on clinical data, 63% (3451/5511, missing values n = 235) and based on billing data 25% (1421/5746) of the participants had thyroid disorders. The sensitivity was 12-36%, the specificity was 84-98%, the PPW was highest for thyroid nodules (75%) and hypothyroidism (70%) and the NPW was between 63 and 94%, depending on the investigated thyroid disorder. CONCLUSIONS: Thyroid disorders are common and often undiagnosed. Billing data have a low sensitivity to identify clinically relevant thyroid disorders.
