Little literature exists on emergencies within primary care offices.We aimed to study the occurrence of emergencies and confidence in dealing with them among primary care physicians (PCPs) in Germany.We conducted a cross-sectional study among all PCPs with licences to practice with an own office (Answers from 375 PCPs could be analysed (response: 41.0%); 95.7% reported at least one emergency in their office within the last 12 months (mean 12.9). PCPs from rural offices reported more emergencies (on average 13.7 vs. 9.6). Acute coronary syndrome, cardiac arrhythmia and dyspnoea were the most common emergencies. A greater likelihood of feeling more confident in managing medical emergencies was found among male physicians, general internists, PCPs additionally qualified as emergency physicians and those with previous training in the emergency department and intensive care unit. In contrast, more general practitioners felt secure treating paediatric emergencies than general internists (highest level of confidence 22.1% vs. 16.3%).In Germany, emergencies in primary care offices occur on average once a month and more often in rural than urban areas. While most PCPs are confident in managing medical emergencies, some differences related to the training path became apparent. Ongoing training programmes may be tailored to improve emergency skills.

Background A shortage of general practitioners (GPs) is common to many European countries. To counteract this, it is essential to understand the factors that encourage or discourage medical students from choosing to become a GP Objective To evaluate medical students’ attitudes towards general practice and to identify factors that discourage them from considering a career as a GP. Methods In this multinational cross-sectional online survey, 29 284 students from nine German, four Austrian and two Slovenian universities were invited to answer a questionnaire consisting of 146 closed and 13 open-ended items. Results Of the 4486 students that responded (response rate: 15.3%), 3.6% wanted to become a GP, 48.1% were undecided and 34.6% did not want to be a GP. Significant predictors for interest in becoming a GP were higher age [odds ratio (OR) = 1.06; 95% confidence interval (CI) = 1.02–1.10], positive evaluation of the content of a GP’s work (OR = 4.44; 95% CI = 3.26–6.06), organizational aspects (OR = 1.42; 95% CI = 1.13–1.78), practical experience of general practice (OR = 1.66; 95% CI = 1.08–2.56) and the country of the survey [Slovenian versus German students (Reference): OR = 2.19; 95% CI = 1.10–4.38; Austrian versus German students (Reference): OR = 0.50; 95% CI = 0.32–0.79]. Conclusion Strategies to convince undecided students to opt for a career as a GP should include a positive representation of a GP’s work and early and repeated experience of working in a general practice during medical school.

Background Provision of ambulatory care by medical specialists for nursing home residents (NHR) is discussed to be inadequate in Germany, however with only incomplete evidence on this topic. We wanted to know whether the transition to a nursing home is associated with a general decrease in medical specialist care and therefore compared contact rates before and after institutionalization. Methods Claims data of 18,779 newly admitted NHR in 2013 were followed for the whole year prior to and up to two years after admission. The frequencies of contacts to specialists were assessed and stratified by sex, age, care level, dementia diagnosis and chronic conditions. Multivariate analyses were conducted to identify predictors for contacts to specialists. Results One year after institutionalization the most pronounced decrease was found in contacts with ophthalmologists (38.4% vs. 30.6%) whereas with most other specialties only small changes were found. The only specialty with a large increase were neurologists and psychiatrists (27.2% vs. 43.0%). Differences depending on sex and age were rather small while NHR with dementia or a higher care level had lower contact rates after institutionalization. Before institutionalization most patients were referred to a specialist by a general practitioner (61.7–73.9%) while thereafter this proportion decreased substantially (27.8–58.6%). The strongest predictor for a specialist contact after admission to a nursing home was a contact to a specialist before (OR 8.8, CI 7.96–9.72 for contacts to neurologists or psychiatrists). A higher nursing care level and a higher age were also predictors for specialist contacts. Conclusions Relevant decreases of ambulatory specialist care utilization after institutionalization are restricted to ophthalmologists. NHR of higher age and higher nursing care level had a lower chance for a specialist contact. The assessment of the adequacy of the provided care after institutionalization remains inconclusive due to little investigated but assumable changes in care needs of NHR. The decreased coordination of care by general practitioners after institutionalization conflicts with health policy goals.

Epistaxis is a common symptom in the medical practice. It is associated with various comorbidities and the use of medications, especially anticoagulants. Despite the high lifetime prevalence, there is limited data on prevalence and possible risk factors.The study examines epistaxis care in a large patient population (AOK Lower Saxony) over a ten-year period (2007-2016). Risk factors, age at diagnosis, concomitant medication and comorbidities were analysed and the prevalence in the study period calculated.162,167 patients visited their doctors between 2007-2016 (308,947 cases). Most patients were treated as outpatients (96.6%) and 54% of patients were men. Over the study period, the prevalence of epistaxis rose by 21% (increase from 8.6 to 9.3 per 1000 insured persons per year) with a comparatively stable prevalence for the inpatient setting (0.2 per 1000 insured persons per year). In 54,105 of all epistaxis cases (17.5%), the use of antithrombotic drugs was recorded (oral anticoagulants: 9.5%). During the study period, increased prescribing of oral anticoagulants (from 7.7% of cases in 2007 to 11.8% in 2016), especially of NOAC was documented (from 0.1% of cases in 2011 to 5.1% in 2016).In addition to arterial hypertension, the predominant male sex and the typical age distribution, we found that cases of epistaxis often received anticoagulation therapy. This study showed an increase of epistaxis along with rising prescriptions of NOAC. In contrast, no increase of severe epistaxis cases leading to hospitalization was found.HINTERGRUND: Die Epistaxis ist ein häufiges Symptom in der Arztpraxis und assoziiert mit verschiedenen Komorbiditäten und Medikamenten, insbesondere Antikoagulanzien. Trotz ihrer Alltäglichkeit gibt es nur wenige Daten zur Häufigkeit ihres Auftretens und möglichen Risikofaktoren.Die Studie untersuchte anhand einer großen Patientenpopulation (AOK Niedersachsen) über 10 Jahre (2007–2016) die Versorgung von Epistaxis in Niedersachsen. Alter bei Diagnose, Begleitmedikation und Komorbiditäten wurden analysiert und die Prävalenz dargestellt.162.167 Versicherte der AOK Niedersachen wurden zwischen 2007 und 2016 aufgrund einer Epistaxis in 308.947 Fällen ärztlich vorstellig. Die meisten Patienten wurden ausschließlich ambulant behandelt (96,6 %). Über den Studienzeitraum stieg die Prävalenz um 21 % (Anstieg von 8,7 auf 9,3 pro 1000 Versicherte/Jahr) bei stabiler Prävalenz für stationäre Vorstellungen (0,2 pro 1000 Versicherte/Jahr). Die höchsten Prävalenzen fanden sich bei Personen bis 20 und über 80 Jahre. In 17,5 % aller Epistaxisfälle wurden Antithrombotika erfasst (9,5 % orale Antikoagulanzien). Über den Studienzeitraum konnte eine erhöhte Verschreibung von Antikoagulanzien (7,7 % in 2007 auf 11,8 % in 2016, insbesondere NOAK) dokumentiert werden.Neben der arteriellen Hypertonie, dem männlichen Geschlecht sowie der typischen Altersverteilung bestand auch häufig eine Medikation mit Antikoagulanzien. Über den untersuchten Zeitraum zeigte sich eine Zunahme von Epistaxisfällen bei gleichzeitig ansteigender Verschreibungshäufigkeit von NOAK, nicht jedoch von schweren hospitalisationsbedürftigen Epistaxisfällen. Eine abschließende Beurteilung hinsichtlich eines möglichen kausalen Zusammenhangs muss in weiteren Studien untersucht werden.

Objectives: On the basis of current treatment guidelines, we developed and validated a medication-based chronic disease score (medCDS) and tested its association with all-cause mortality of older outpatients.Study Design and Setting: Considering the most prevalent chronic diseases in the elderly German population, we compiled a list of evidence-based medicines used to treat these disorders. Based on this list, a score (medCDS) was developed to predict mortality using data of a large longitudinal cohort of older outpatients (training sample; MultiCare Cohort Study). By assessing receiver-operating characteristics (ROC) curves, the performance of medCDS was then confirmed in independent cohorts (ESTHER, KORA-Age) of community-dwelling older patients and compared with already existing medication-based scores and a score using selected anatomical-therapeutic-chemical (ATC) codes.Results: The final medCDS score had an ROC area under the curve (AUC) of 0.73 (95% CI 0.70-0.76). In the validation cohorts, its ROC AUCs were 0.79 (0.76-0.82, KORA-Age) and 0.74 (0.71-0.78, ESTHER), which were superior to already existing medication-based scores (RxRisk, CDS) and scores based on pharmacological ATC code subgroups (ATC3) or age and sex alone (Age&Sex).Conclusions: A new medCDS, which is based on actual treatment standards, predicts mortality of older outpatients significantly better than already existing scores.

Background Due to the increasing number of non-urgent visits to emergency departments, it is becoming increasingly important to also investigate emergency care in out-of-hours (OOH) primary care. The aim of this study was to provide an insight into the care structures of an OOH primary care centre, to evaluate the reasons for encounter (RFE) and to assess the urgency of the treatment from the physicians´ point of view. Methods In the summer of 2017, we conducted a cross-sectional study over four weeks in the OOH primary care centre of Oldenburg, a city in Lower Saxony with about 160,000 inhabitants. We collected socio-demographic data, RFE and the duration of the complaints. The International Classification for Primary Care 2nd Edition (ICPC-2) was used to categorize symptoms. The attending physicians supplemented information on further treatment (including hospitalization) and the urgency of consultation in the OOH primary care centre. Results A total of 892 of the 1098 OOH patients which were visiting the OOH primary care centre took part in the study (participation: 81.2%). More than half of the patients were between 18 and 39 years old. A quarter of all RFE named by study participants were in the ICPC-2 category “skin”. More than 60% of patients had the symptoms for more than two days before visiting the OOH primary care centre. In 34.5% of all cases no medication was prescribed and one in six patients received further diagnostic tests such as urinalysis and blood tests (15.8%). From the physicians’ point of view, 26.3% of all study participants could have been treated by the family doctor during the regular consultation hours. Conclusion The study shows that in the OOH primary care centre about a quarter of all patients could have waited until regular consultation hours. Mostly young patients used the easily accessible and free care in the OOH primary care centre. Further studies are necessary to better understand the individual reasons of patients to use the OOH primary care centre.

Importance Controversies about the choice of antibiotic agent and treatment modality exist in the management of erythema migrans in early cutaneous Lyme borreliosis (LB). Objective To conduct a network meta-analysis (NMA) of all randomized clinical trials on various antibiotic agents and treatment modalities in early cutaneous LB. Data Sources Electronic searches in MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials were conducted from inception until July 2017. The reference lists of the included studies were hand searched, authors were contacted, and ongoing trials were searched at ClinicalTrials.gov. Study Selection One reviewer screened the titles and abstracts of the 9975 reports identified by the electronic searches. Full-text copies of 161 potentially relevant articles were obtained, and 2 reviewers independently assessed those articles for inclusion. Adults with a physician-confirmed early localized skin infection who were treated with antibiotics of any dose or duration were included. Data Extraction and Synthesis Two reviewers independently extracted data on study, patient, and intervention characteristics. Network meta-analyses on treatment effects and adverse outcomes were calculated with a frequentist approach using the R package netmeta. The Grading of Recommendations Assessment, Development and Evaluation guidance for NMA was used to assess the certainty of evidence. Main Outcomes and Measures Treatment effects for response to treatment (resolution of symptoms) and treatment-related adverse events. Results Overall, 19 studies (2532 patients) were included. The mean patient age ranged between 37 and 56 years, and the percentage of female patients ranged from 36% to 60%. The antibiotics investigated were doxycycline, cefuroxime axetil, ceftriaxone, amoxicillin, azithromycin, penicillin V, and minocycline. Pooled effect sizes from NMAs did not suggest any significant differences in treatment response by antibiotic agent (eg, amoxicillin vs doxycycline odds ratio, 1.26; 95% CI, 0.41-3.87), dose, or duration (eg, doxycycline, 200 mg/d for 3 weeks, vs doxycycline, 200 mg/d for 2 weeks, odds ratio, 1.28; 95% CI, 0.49-3.34). Treatment failures were rare at both 2 months (4%; 95% CI, 2%-5%) and 12 months (2%, 95% CI, 1%-3%) after treatment initiation. There were also no differences in the effect sizes among antibiotic agents and treatment modalities for treatment-related adverse outcomes, which were generally mild to moderate. Certainty of evidence was categorized as low and very low mostly because of imprecision, indirectness, and study limitations (high risk of bias) of the included studies. Conclusions and Relevance This NMA suggests that neither the antibiotic agent nor treatment modality contributed to comparative effectiveness or drug-related adverse outcomes. This finding is relevant for physicians treating patients with LB and for patient decision making.

Aims This population-based study assesses the healthcare utilization of people with Type 2 diabetes by analysing routine data from Allgemeine Orts-Krankenkasse (AOK), the largest statutory health insurance provider in Germany. Methods Anonymized billing data from all AOK-insured persons with at least one day of insurance during the evaluation year 2010 were analysed. Treatment and cost data from all areas of inpatient and outpatient care were available, as was information regarding patient age and sex. International Classification of Diseases (ICD–10) diagnosis and Anatomical Therapeutic Chemical (ATC) classification were used to identify 2.7 million insured persons with diabetes. Results The age- and sex-standardized prevalence of Type 2 diabetes was 9.8%. Of those patients identified, 33.9% had at least one diabetes-related complication and 83.0% had a diagnosis of hypertension. Almost two-thirds (63.1%) received antihyperglycaemic medication. Metformin and sulfonylurea were prescribed most often; medications without proof of benefit in endpoint studies were prescribed much less frequently. People without diabetes were admitted to hospital only half as often as those with Type 2 diabetes. The projected total expenditure in Germany for all people with Type 2 diabetes amounted to approximately €33.3 billion in 2010. Conclusions This study shows an increase in both the prevalence of diabetes and treatment costs. The majority of people with Type 2 diabetes were aged 70 years or older. One third of this group has diabetes-related complications. Antihyperglycaemic medications without proof of benefit in endpoint studies were prescribed much less frequently than drugs with proof of benefit.

Summary 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.

Background: Influenza vaccination coverage in Germany does not meet the recommendation of the World Health Organization. Nursing home residents are an especially vulnerable subgroup. It is not known whether vaccination coverage rates differ between nursing home residents and non-institutionalised persons[for full text, please go to the a.m. URL], 51.

Background: To test whether quality of life depends on the psyche of patients after successful bypass surgery for peripheral arterial disease (PAD). Patients and methods: A total of 74 consecutive patients aged 36–69 years (57.7 ± 8.8 years) with symptomatic PAD in the stages Fontaine IIb–IV were enrolled in a prospective study after successful bypass surgery. Because of bypass failure and one death during the study period, 11 of these patients were excluded from evaluation. Prior to surgery, Doppler sonography and digital subtraction angiography were carried out in all patients. Before and after revascularization, the ankle / brachial index (ABI) was determined in all study objects and the pain free walking distance (PFWD) in those with PAD stage Fontaine IIb. Health-related quality of life was measured by using the "Medical Outcomes Study Group Short Form 36" (SF-36), and personality was determined by employing the Psycho-Diagnostic-Test (PDT). Results: After surgery, there was an increase in ABI from 0.32 ± 0.13 to 0.79 ± 0.19 (p < .01), in PFWD from 42.6 m ± 38.6 m to 419.7 m ± 152.3 m (p < .01), and in the SF-36 scales "Physical functioning", "Bodily pain", "General health perceptions", and "Role-functioning physical" (p < .05). ABI correlated positively with "Bodily pain" (p < .01), "General health perceptions" (p < .01) and "Mental health" (p < .05). Among SF-36 and PDT-scales, "Role-functioning physical" correlated negatively with "Moodiness" / "Neuroticism" (p < .05), and "Social functioning" correlated positively with "General activity" (p < .01). Conclusions: Whether objective clinical improvement increases quality of life mainly depends on the psyche of patients: A high level of general activity favors an improved quality of life and neurotic characteristics are more likely to be a hindrance.

Introduction Benign epilepsy with centrotemporal spikes (BECTS) is a common epilepsy syndrome in childhood. Besides the occurrence of seizures, mild cognitive impairments and behavioral problems affecting language skills, spatial perception, memory, executive function, and academic achievement might be present. There is no international consensus about the decision whether or not to treat affected children. The influence of treatment on cognitive functions is debated. Methods Patients diagnosed with BECTS were assessed in short term auditory memory, long-term verbal memory, intelligence and behavior using the “number recall” test from the Kaufman assessment battery for children, the “verbal learning memory test”, the “culture free intelligence test” and the “child behavior checklist” prior to a randomized controlled antiepileptic therapy and after a treatment period of 6 months with either sulthiame or levetiracetam. Results 43 of 44 randomized patients were analyzed. One patient had to be excluded due to protocol violation. Patients who completed the study showed a non-significant improvement in parent-reported behavioral problems under therapy. Cognitive skills were not affected. Conclusion The present data suggest that antiepileptic drug treatment of children with BECTS with either sulthiame or levetiracetam does not affect cognitive performance. Behavior improved in a subset of patients though not reaching statistical significance.

Background Erythema migrans represents an early cutaneous and most common manifestation of Lyme borreliosis. Recommendations regarding pharmacological agents, dose and duration of treatment are subject of intense debate. This review aims to explore differences in efficacy and safety between pharmacological treatments and control treatment. Methods To identify relevant studies, we will conduct a systematic literature search. We will include randomised controlled trials (RCTs) and non-RCTs. Eligible comparative studies need to (1) consider patients with a diagnosis of erythema migrans resulting from Lyme borreliosis and (2) compare different pharmacological agents against each other, against any other non-pharmacological treatment, placebo or no treatment. Two review authors will independently assess included studies for risk of bias according to the methods of the Cochrane Handbook for Systematic Reviews of Interventions and related to specific study designs. We will address patient-relevant outcomes including clinical remission of cutaneous symptoms, any treatment-related adverse events, quality of life and progressive symptoms such as neuroborreliosis or Lyme carditis and flu-like symptoms. Provided that the identified trials are comparable in terms of clinical issues, combined estimates will be provided. Estimations of treatment effects will be calculated based on a random effects model. Heterogeneity will be evaluated based on I2 and chi-square test. In case of significant heterogeneity, a pooled estimate will not be provided, but heterogeneity will be investigated on the basis of methodological and clinical study aspects. We plan subgroup analysis to reveal potential differences in the effect estimates between patient populations and treatment specifications. We will consider risk of bias using sensitivity analyses to decide whether to rely on the pooled estimates. The quality of a body of evidence for individual outcomes will be assessed using the GRADE approach. Discussion Benefits and harms of pharmacological treatment in erythema migrans have not yet been adequately assessed. This systematic review will evaluate and summarise available evidence addressing benefits and harms of different pharmacological treatments. In addition, this summary of clinical evidence will inform decision-making between clinicians and patients and will play an important part in patient care.

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.This study was carried out to examine the prescription of analgesics in nursing home residents with and without the diagnosis of cancer.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.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.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.

Increased brain natriuretic peptide (BNP) expression in the ventricles antedates elevated blood pressure (BP) in experimental studies. We hypothesized that higher plasma BNP levels in nonhypertensive individuals may be associated with a greater likelihood of future BP increase and/or hypertension. We evaluated the relations of plasma BNP to longitudinal BP tracking and incidence of hypertension in 1801 nonhypertensive Framingham Heart Study participants (mean age, 56 years; 57% women) by using gender-specific multivariable logistic regression. Progression of BP stage was defined as an increment of one or more BP categories, as classified by the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC VI). Hypertension was defined as a systolic BP ≥140 or diastolic BP ≥90 mm Hg or use of antihypertensive medications. On follow-up 4 years from baseline, progression of BP category was observed in 36.2% of men and 33.1% of women; hypertension developed in 16.4% of men and 15.5% of women. In multivariable models adjusting for known risk factors, elevated plasma BNP level was associated with increased risk of BP progression in men (odds ratio of 1.15 for trend across categories, P =0.046) but not in women ( P =0.82). There were no significant trends of increasing incidence of hypertension across BNP categories in men or women. In our community-based sample, higher plasma BNP levels were associated with increased risk of BP progression in men but not women. Additional investigations are warranted to confirm these findings and elucidate the basis for these gender-related differences.

Introduction Multimorbidity is a major concern in primary care. Nevertheless, evidence of prevalence and patterns of multimorbidity, and their determinants, are scarce. The aim of this study is to systematically review studies of the prevalence, patterns and determinants of multimorbidity in primary care. Methods Systematic review of literature published between 1961 and 2013 and indexed in Ovid (CINAHL, PsychINFO, Medline and Embase) and Web of Knowledge. Studies were selected according to eligibility criteria of addressing prevalence, determinants, and patterns of multimorbidity and using a pretested proforma in primary care. The quality and risk of bias were assessed using STROBE criteria. Two researchers assessed the eligibility of studies for inclusion (Kappa = 0.86). Results We identified 39 eligible publications describing studies that included a total of 70,057,611 patients in 12 countries. The number of health conditions analysed per study ranged from 5 to 335, with multimorbidity prevalence ranging from 12.9% to 95.1%. All studies observed a significant positive association between multimorbidity and age (odds ratio [OR], 1.26 to 227.46), and lower socioeconomic status (OR, 1.20 to 1.91). Positive associations with female gender and mental disorders were also observed. The most frequent patterns of multimorbidity included osteoarthritis together with cardiovascular and/or metabolic conditions. Conclusions Well-established determinants of multimorbidity include age, lower socioeconomic status and gender. The most prevalent conditions shape the patterns of multimorbidity. However, the limitations of the current evidence base means that further and better designed studies are needed to inform policy, research and clinical practice, with the goal of improving health-related quality of life for patients with multimorbidity. Standardization of the definition and assessment of multimorbidity is essential in order to better understand this phenomenon, and is a necessary immediate step.

Background Neuroborreliosis is a tick-borne infectious disease of the nervous system caused by Borrelia burgdorferi. Common clinical manifestations of neuroborreliosis are cranial nerve dysfunctions, polyradiculoneuritis, and meningitis. Diagnosis is usually based on clinical presentation, serologic testing, and analysis of cerebrospinal fluid. Many aspects of pharmacological treatment, such as choice of drug, dosage, and duration are subject of intense debate, leading to uncertainties in patients and healthcare providers alike. To approach the questions regarding pharmacological treatment of neuroborreliosis, we will perform a systematic review. Methods We will perform a comprehensive systematic literature search for potentially eligible studies that report outcomes after pharmacological interventions. To adequately consider the wealth of research that has been conducted so far, this review will evaluate randomized controlled trials (RCTs) and non-randomized studies on treatment of neuroborreliosis. We will assess potential risk of bias for each RCT meeting our selection criteria using the Cochrane risk of bias tool for RCTs. For non-randomized studies, we will use the Newcastle-Ottawa Scale and the recently piloted Cochrane risk of bias tool for non-randomized studies. Our primary outcome of interest will be neurological symptoms and the secondary outcomes will be disability, patient-reported outcomes (quality of life, and, if reported separately from other neurological symptoms, pain, fatigue, depression, cognition, and sleep), adverse events, and cerebrospinal fluid pleocytosis. Pooling of data and meta-analysis will only be deemed justified between studies with similar design (e.g., RCTs are only combined with other RCTs), characteristics (e.g., similar populations), and of acceptable heterogeneity (I2

Older patients, suffering from numerous diseases and taking multiple medications are the rule rather than the exception in primary care. A manifold of medical conditions are often associated with poor outcomes, and their multiple medications raise additional risks of polypharmacy. Such patients account for most healthcare expenditures. Effective approaches are needed to manage such complex patients in primary care. This paper describes the results of a scoping exercise, including a two-day workshop with 17 professionals from six countries, experienced in general practice and primary care research as well as epidemiology, clinical pharmacology, gerontology and methodology. This was followed by a consensus process investigating the challenges and core questions for multimorbidity research in primary care from a clinical perspective and presents examples of the best research practice. Current approaches in measuring and clustering multimorbidity inform policy-makers and researchers, but research is needed to provide support in clinical decision making. Multimorbidity presents a complexity of conditions leading to individual patient's needs and demanding complex processes in clinical decision making. The identification of patterns presupposes the development of strategies on how to manage multimorbidity and polypharmacy. Interventions have to be complex and multifaceted, and their evaluation poses numerous methodological challenges in study design, outcome measurement and analysis. Overall, it can be seen that complexity is a main underlying theme. Moreover, flexible study designs, outcome parameters and evaluation strategies are needed to account for this complexity. © 2014 Informa Healthcare.

Background. Data on the economic impact of Lyme borreliosis (LB) on European health care systems is scarce. This project focused on the epidemiology and costs for laboratory testing in LB patients in Germany.Materials and Methods. We performed a sentinel analysis of epidemiological and medicoeconomic data for 2007 and 2008. Data was provided by a German statutory health insurance (DAK) company covering approx. 6.04 million members. In addition, the quality of diagnostic testing for LB in Germany was studied.Results. In 2007 and 2008, the incident diagnosis LB was coded on average for 15,742 out of 6.04 million insured members (0.26%). 20,986 EIAs and 12,558 immunoblots were ordered annually for these patients. For all insured members in the outpatient sector, a total of 174,820 EIAs and 52,280 immunoblots were reimbursed annually to health care providers (cost: 2,600,850€). For Germany, the overall expected cost is estimated at 51,215,105€. However, proficiency testing data questioned test quality and standardization of diagnostic assays used.Conclusion. Findings from this study suggest ongoing issues related to care for LB and may help to improve future LB disease management.

BACKGROUND: Slow hospital discharges reduce efficiency and compromise care for patients awaiting a bed. Although efficient discharge is a widely held goal, the natural history of the discharge process has not been well studied. OBJECTIVE: To describe the discharge process and identify factors associated with longer and later discharges. DESIGN: Prospective cohort study. SETTING: A general medicine ward without house-staff coverage, in a tertiary care hospital (The Johns Hopkins Hospital) in Baltimore, Maryland, from January 1, 2005 to April 30, 2005. PATIENTS: Two hundred and nine consecutively discharged adult inpatients. MEASUREMENTS: Discharge time (primary outcome) and discharge duration (secondary outcome). RESULTS: Median discharge time was 3:09 PM (25th% to 75th%: 1:08 to 5:00 PM). In adjusted analysis, discharge time was associated with ambulance used on discharge (1.5 hours), prescriptions filled prior to discharge (1.4 hours), subspecialty consult prior to discharge (1.2 hours), and procedure prior to discharge (1.1 hours). Median duration of the discharge process was 7 hours 34 minutes (25th% to 75th%: 4.0 to 22.0 hours). Discharge duration was associated with discharge to a location other than home (28.9 hours), and with need for consultation (14.8 hours) or a procedure (13.4 hours) prior to discharge (all P values

Twenty-six Austrian, Dutch, German, and Swiss epilepsy centers were asked to report on use of the Wada test (intracarotid amobarbital procedure, IAP) from 2000 to 2005 and to give their opinion regarding its role in the presurgical diagnosis of epilepsy. Sixteen of the 23 centers providing information had performed 1421 Wada tests, predominantly the classic bilateral procedure (73%). A slight nonsignificant decrease over time in Wada test frequency, despite slightly increasing numbers of resective procedures, could be observed. Complication rates were relatively low (1.09%; 0.36% with permanent deficit). Test protocols were similar even though no universal standard protocol exists. Clinicians rated the Wada test as having good reliability and validity for language determination, whereas they questioned its reliability and validity for memory lateralization. Several noninvasive functional imaging techniques are already in use. However, clinicians currently do not want to rely solely on noninvasive functional imaging in all patients.

To develop a disease-specific measuring instrument for quality of life in German-speaking patients with peripheral arterial occlusive disease in the stage of critical ischemia and to test it in a prospective study for validity and reliability.We developed a questionnaire compiling items representing subjective disease relevant health states. With 35 of these items, we designed the scales comorbidity (KO), physical pain (SZ), physical functioning (KF), physical state (KS), social functioning (SB), mental health (PB), and therapy-induced limitations (TE). Each item was to be valued as never, seldom, often or always. The scales were standardized with a control group of 40 individuals without peripheral arterial occlusive disease who were interviewed twice in an interval of 6 months using both the FLeQKI and the Medical Outcomes Study Group Short Form 36 (SF-36). Convergent and discriminative validity was determined in 65 consecutive in-patients with peripheral occlusive arterial disease in the stage of critical ischemia who were interviewed with FLeQKI and SF-36 prior to percutaneous transluminal angioplasty (PTA) or bypass operation and 1 month and 6 months after. The internal consistency and test-retest reliability of the FLeQKI were determined in the control group. For statistical analysis, Cronbach's alpha Test and Pearsons Product Moment Correlation were used.The control group consisted of 21 men and 19 women with an age of 73.4+/-7.8, and the treatment group was comprised of 35 men and 30 women with an age of 75.1+/-7.0. In the treatment group, convergent validity reached high values in the scales SB, KF, PB, and SZ (r=0.41-0.70). With their discriminative validity (r=-0.04-0.30), TE and KS were independent, specific dimensions of life quality. The control group showed good values for internal consistency (Cronbach's alpha=0.54-0.93) and for test-retest reliability (r=0.44-0.96).The FLeQKI is well suited for determining the specific impairments of life quality in patients with peripheral arterial occlusive disease at the stage of critical ischemia. Its psychometric scores for validity and reliability corresponded to those of the SF-36.

To test the "Questionnaire for Life Quality in Patients with Peripheral Arterial Occlusive Disease at the Stage of Critical Ischemia" (FLeQKI) in a prospective study with respect to responsiveness and practicability.The responsiveness of the FLeQKI for therapy-induced changes of health related quality of life was prospectively determined in 65 consecutive patients with peripheral occlusive arterial disease at the stage of critical ischemia prior to percutaneous transluminal angioplasty (PTA) or bypass operation, and 1 month and 6 months after. 40 healthy individuals who were matched for age and questioned with the FLeQKI twice within 6 months served as the control. Additionally, all patients and healthy volunteers were questioned with the "Medical Outcomes Study Group Short Form" (SF-36). In all patients, the ankle/brachial index (ABI) was measured along with each of the three interviews. To validate practicability, we measured the time needed to fill out the questionnaires and asked the patients to indicate on a visual analog scale (VAS) graduated from 0 - 10 how strenuous they found the questionnaires to be. For statistical analysis, two-sided paired t-tests were used.The treatment group consisted of 35 men and 30 women with an age of 75.1+/-7.0 years, and the control group was comprised of 21 men and 19 women with an age of 73.4+/-7.8 years. In the control group, none of the FLeQKI scales showed significant changes over time (p0.05). In the pAVK group, all scales improved between the interviews before and 6 months after therapy. Changes were either significant (comorbidity, p0.05) or highly significant (all other scales, p0.005 or p0.0001). ABI increased above 0.5 (p0.05). With an average of 12 minutes, the FLeQKI required less time than the SF-36 with an average of 15.57 minutes (p0.05). Both questionnaires were evaluated with a VAS value of less than 1 (p0.05) as non-strenuous.Regarding responsiveness and practicability, the FLeQKI is well suited for determining the specific impairments of life quality in patients with peripheral arterial occlusive disease in the stage of critical ischemia. Compared with the SF-36, the FLeQKI reached similar or better psychometric values.

Relevant criteria to assess specific diseases have been heavily discussed since Rudolf Virchow when morphologic changes represented the center of interest. However, nowadays presence and severity of disease cannot exclusively depend on the mere absence or presence of morphologic criteria anymore. The progress in basic and clinical science, moral values and economic constraints imply to reflect, concretize and ultimately operationalize the goals of medical therapy. Recent advances in molecular biology and genetics have lead to further understanding of pathophysiological mechanisms of disease and opened new ways for sophisticated and individualized therapeutical approaches. It is important to reconsider the definition of health and appropriately address functional and quality of life aspects. The categorical classification of therapeutical options, i.e. curative versus palliative therapy, does not provide satisfying answers to several clinical scenarios such as early stage prostate cancer in older adults or functional limitations in patients with peripheral arterial disease. Clinical research does acknowledge increasingly that relevant outcomes extend well beyond the quantitative prolongation of life. The scientific field of health services research is supposed to increase the evidence base of these decisions. Lastly, the goals of therapy should not be defined by physicians alone. It is important to inform the patient appropriately and discuss individual prognosis, therapeutical options and goals. Ultimately, therapy should be based on a shared decision making process.

To determine the current incidence of major amputations, bypass procedures and percutaneous transluminal angioplasties (PTA) in a study population of patients with peripheral arterial occlusive disease in a German referral center.In a retrospective study, we recruited patients with peripheral arterial occlusive disease who underwent an amputation, bypass procedure, or PTA in the region of the pelvis or lower limbs between 1996 and 2003 at the Augsburg Medical Center. Patients were identified via the hospital database. This was performed with the help of the International Classification of Diseases (ICD 9 and 10), the operation code (OPS), and appropriate invoices. The incidence of PTAs was further estimated with 200 charts.Of 5379 patients, 627 underwent amputation, 1832 a bypass procedure, and 2920 a PTA. The incidence of PTAs increased during the study period from 51.3/100 000/year to 64.4/100 000/year (p0.01), while the number of amputations and bypass procedures remained stable. The incidence of PTAs was exceeded by that of bypass procedures only in patients older than 85 years. The age of the amputees decreased during the study period from 72.2 to 70.5 years (p0.01). The age of patients who underwent a bypass procedure increased from 67.2 to 69.4 years, and the age of patients who underwent PTA increased from 66.3 to 69.8 years (p0.01). Bypass procedures and PTAs were performed in men 6.3 years earlier than in women (p0.01).The result is a population-corrected need of 8.4/100 000/year major amputations, 23/100 000/year bypass procedures and 64.4/100 000/year PTAs for patients with peripheral arterial occlusive disease within the referral area of our hospital. The performance of major amputations and bypass procedures stagnates, while the incidence of PTAs is increasing.

Hip fractures are among the most important causes for disability, reduced quality of life, and death in older persons. Hip fracture patients are typically characterized by older age and a large complexity in their underlying conditions, comorbidities, and clinical histories. Therefore, large, well-designed studies are difficult to perform and the available evidence for most treatments is limited compared with other disease entities of this magnitude. This paper illuminates the current issues and recommendations for post-operative hip fracture care. Efforts to improve osteoporosis assessment and management, the multidisciplinary team approach, and clinical pathways are areas that have received attention recently.

Background and Purpose— Previous studies have shown that midlife systolic blood pressure (SBP) predicts late-life cognitive decline and incident dementia. This study explores whether this association is attributable to the pulsatile, ie, pulse pressure (PP), or the nonpulsatile component of blood pressure (BP). Methods— Data are from the Honolulu-Asia Aging Study, a community-based study of Japanese American men. Midlife BP was measured in 1971 to 1974 and dementia assessment was conducted in late-life. The 2505 men who were dementia free in 1991 and had complete follow-up data were re-examined for incident dementia in 1994 to 1996 and 1997 to 1999. Their age ranged from 71 to 93 years. Survival analysis with age as the time scale was performed to estimate the risk (hazard ratio [HR] and 95% CI) for incident dementia associated with mid- and late-life tertiles of PP and mean arterial BP, as well as SBP and diastolic BP categories. Results— Over a mean of 5.1 years of follow-up, 189 cases (7.5%) of incident Alzheimer disease or vascular dementia were identified. After adjustment for cerebrovascular risk factors, dementia was significantly associated with SBP (HR 1.77; 95% CI, 1.10 to 2.84, for SBP ≥140 mm Hg compared with SBP Conclusions— Midlife PP is not independently associated with dementia incidence. Midlife SBP is the strongest BP component predicting incident dementia.

Congestive heart failure (CHF) is a disease condition that is increasing in prevalence and is associated with significant morbidity and mortality. Left ventricular systolic dysfunction (LVSD) is a treatable precursor of CHF, but remains asymptomatic in about half of the individuals afflicted. This observation has spurred interest in screening for LVSD. Plasma B-type natriuretic peptide (BNP) is a widely accepted test for the diagnosis of overt CHF. In this review, we examine the potential role for plasma BNP as a screening tool for asymptomatic LVSD. The performance of any screening test depends on its accuracy, the prevalence of the disease condition screened for, and the availability of resources for follow-up of individuals in whom the disease was detected. In the context of community-wide screening for LVSD, a test with high specificity would be important so as to minimize the costs of expensive definitive follow-up tests (i.e. echocardiography). The prevalence of significant LVSD (ejection fraction 20.40) is low, limiting the enthusiasm for a screening program targeting the general population. This is especially true for women, in whom the condition is rare, and the performance characteristics of plasma BNP are sub-optimal. In men, plasma BNP may be a useful screening test in high-risk individuals in whom there are no other clinical indications for echocardiography. The choice of the appropriate plasma BNP threshold that triggers further work-up in such high-risk individuals may vary according to the availability of resources, and with the healthcare priorities of a community.

Tuberous sclerosis complex (TSC) is frequently associated with focal epilepsy due to cerebral tubers. Seizures are the first symptoms in most patients with brain involvement. These epilepsies are frequently severe, drug-resistant and may have a negative impact on the child's global development. Although most epilepsies are multicentric, these patients may be candidates for epilepsy surgery, if it is possible to determine a leading epileptogenic tuber. Nine patients with TSC were examined with long-term video-EEG monitoring, different neuroimaging techniques and neuropsychological tests. A main epileptogenic tuber could be identified in all of our patients. We found good correlations between neuroimaging and EEG. Surgery was performed in eight patients. Seizure outcome was good in all. Two patients became seizure-free, one patient had a single prolonged seizure five days postoperatively, four patients had a significant seizure reduction of more than 75 % and one patient had a seizure reduction of more than 50 % after surgery without additional neurologic deficits. In conclusion, patients with TSC and drug-resistant epilepsy may benefit from epilepsy surgery with reduction in frequency and severity of seizures as well as improved mental and behavioural development leading to a better quality of life. In view of recent developments in functional and metabolic imaging, primary epileptogenic lesions will be more easily detectable in patients with diffuse brain involvement in TSC and surgical treatment may be more specifically applied at an earlier age to a selected subgroup of patients with this disorder.

Aspiration of gastric content frequently induces early onset of pneumonia in patients with impaired consciousness after closed head injury and thus worsens the prognosis. Early detection of aspiration and appropriate therapy are essential. The purpose of the study was to assess the diagnostic value of procalcitonin (ProCT) in aspiration of gastric content and to evaluate its prognostic impact in patients with closed head injury.Twenty-three patients with isolated closed head injury (Glasgow Coma Scale [GCS] scoreor = 8) were studied. Bronchoscopy was done on admission; chest radiographs and routine laboratory examination including C-reactive protein were performed daily. ProCT was analyzed 12, 24, 36 and 72 hours after trauma using an immunoluminometric assay.ProCT was higher throughout the study period in 9 patients with persistent radiological signs suspect for aspiration of gastric content and there was evidence of aspiration of gastric content during bronchoscopy on admission. Median ProCT values of 1.397 ng/ml (range, 0.372 to 8.358 ng/ml) on admission increased to 2.144 ng/ml (range, 0.716 to 6.910 ng/ml) 24 hours after trauma, and then decreased to baseline values of 1.711 ng/ml (range, 0.611 to 6.639 ng/ml) as early as 36 hours after trauma. In patients without signs of aspiration of gastric content, ProCT values did not exceed 0.418 ng/ml. Non-survivors had higher serum levels of ProCT throughout the study period.Our findings suggest that ProCT is a useful diagnostic marker for detecting aspiration of gastric content while the prognostic value of ProCT for predicting survival after isolated closed head injury was moderate.

The cuffed oropharyngeal airway (COPA), a modified Guedel-type airway with a cuff at the distal end, has recently been introduced into anesthetic practice. The aim of this study was to compare the COPA with the well established laryngeal mask airway (LMA). Special consideration was granted to the difficult airway.Two hundred and fifty-two women of ASA class I or II undergoing elective gynecological or breast surgery under general anesthesia were randomly assigned to either cuffed oropharyngeal or laryngeal mask airway management. Insertion and removal of the device, airway maintenance throughout the procedure, and postoperative course and complications were assessed.A patent airway was obtained with either device in all patients. Global first-time success rates for insertion were similar in the two study groups. Initial failure of correct placement occurred more frequently in the COPA as compared to the LMA group if the interincisor gap was5 cm and mandibular protrusion impossible (p0.01). Neither thyromental distance nor Mallampati scores nor body mass index (BMI) were of relevance for insertion success. The incidence of postoperative complaints and of mucosal injuries was significantly higher with the LMA.On the whole, high overall success and low complication rates render COPA and LMA equally suitable for routine anesthetic airway management.

Electrical stimulation of the vestibular system may prevent nausea and vomiting. We studied the influence of transcutaneous impulse stimulation in prevention of postoperative nausea and vomiting (PONV) following gynaecological surgery.In this randomised study 70 women undergoing elective gynaecological surgery under general anaesthesia were assigned to receive either the activated (stimulation group) or the inactivated (non-stimulation group) impulse stimulator. The stimulator comprises the stimulator itself, two negative electrodes on a headset applied over both mastoid processes and a nuchal positive electrode. The device yielded a pulse frequency of 5 Hz direct current, individually adjustable between 0.5 and 4 mA. A trapezoid stimulation of 50 ms was applied. Nausea, vomiting, dizziness and the amount of antiemetic drugs used were assessed during the first 4 h postoperatively.Lower postoperative nausea scores with a lower incidence of vomiting and postoperative dizziness were found in the stimulation group. A lower amount of antiemetic drugs was needed in the stimulation group when compared to the non-stimulation group (P0.01 between groups).This study suggests that electrical stimulation of the vestibular system may be useful in prevention of PONV.

Breast surgery is frequently associated with post-operative nausea, vomiting, pain and painful restricted movement. Paravertebral block may be an alternative to general anaesthesia for this type of surgery. We studied the single-injection paravertebral block at the level of T4 and report a comparison of single-injection paravertebral block to general anaesthesia for breast surgery.After written informed consent was obtained, 86 patients were enrolled in this prospective study. Forty-four women were randomly allocated to receive a single-injection paravertebral block at the level of T4, while 42 women received general anaesthesia. The surgical procedures varied from lumpectomy (wide local excision of a tumour) to modified radical mastectomy with axillary dissection. The block was performed according to the guidelines described by Eason and Wyatt using 0.3 ml x kg(-1) (maximum dose 150 mg) of bupivacaine 0.5%. The skin and the underlying tissues were infiltrated with local anaesthetic solution two fingers (about 3 cm) from the anatomical midline and level with the cephalad end of the vertebral spine.Time for performance of blocks lasted from 4 to 9 min. Recovery from anaesthesia or sedation was shortened, while postoperative pain scores (VAS), the incidence of vomiting and the requirement for analgesics were lower in the paravertebral group. Less painful restricted movement was observed in the paravertebral block group. Paravertebral block was inadequate in 6.8% of patients. Epidural spread with paraparaesis and Horner triad was assumed in one patient.Single-injection paravertebral block at the level of T4 represents a suitable alternative to general anaesthesia in women undergoing breast surgery.

In cataract surgery high quality is demanded. That is why high precision in calculation of IOL power is necessary for predicting postoperative refraction.In a series of 103 patients the predicted refraction--calculated by the SRK II formula for only one type of IOL (A-constant 118.9)--was compared to the received early and late (3 month) postoperative refraction.The accuracy of IOL calculations in 95% was acceptable--within a range of 2 diopters. The prediction errors of extended values were only shown in cases of axial length of more than 26 millimeters.The results confirm the fact that by means of SRK II formula the accuracy of IOL calculation is satisfactory in respect of predicted refraction. In eyes of elongated axial length the accuracy is limited.

The present work deals with the problem of abdominal injuries in polytraumatized patients. The results were obtained from a retrospective study of the records of 530 polytraumatized patients treated at the Central Hospital of the German Federal Armed Forces (Bundeswehr). In all, 193 of these patients had abdominal injuries. The overall mortality was 23.8% (n = 126): mortality among the patients with abdominal injuries was 26% (n = 50). Abdominal injuries alone led to death in 9.1% (n = 1), but mortality increased to 18.4% when at least one extra-abdominal injuries was also present. A combination of abdominal injuries and two or more extra-abdominal lesion led to a mortality rate of 27%. Mortality was found to be age- and sex-related: in young children and patients over 55 years (especially those around 70) mortality was 33.3%-72%. Among the cases with fatal outcome there was a female-to-male ratio of 3:2. The most common causes of death were: hemorrhage shock (62.3%), head injuries (37.7%), septicemia (8.1%), pneumonia, and ARDS (5.4% each). Within the last eight years we have used the following supplementary examination methods: computed tomography, peritoneal lavage, and ultrasonography. The retrospective study has shown that CT is not the examination of choice. The reliability with lavage and ultrasonography was approximately the same, but lavage was found to be more dangerous. Therefore, we abandoned lavage and used sonography only. However, we are of the opinion that any surgeon should use the examination method that has yielded the best results for him or her, to ensure the best possible outcome for the patient.

Gallbladder septa, for example, in "phrygian cap" deformity, may in rare cases lead to a misdiagnosis of gallbladder stones when B-mode ultrasound with gray scale is used. Among 4,000 upper abdominal ultrasound examinations which included the gallbladder one such case was observed. In view of the frequency of septated gallbladders (about 15%) this, although very rare, cause of false-positive diagnosis of stone should be taken into consideration when interpreting ultrasound tracings.

It was examined whether in anatomically intact specific adenic parenchyma of the gastric mucosa achlorhydria can persist after maximal stimulation or whether there is support to the conception of functional achlorhydria ("functional anacidity") furthermore. Relating to the anatomic structure of the gastric mucosa secretion of chloric acid was studied after submaximal and maximal stimulation in 101 cases. It was shown that there is no correlation between the morphology and the secretion of chloric acid in anatomically intact gastric mucosa after submaximal stimulation. In 18 cases out of 28 only the secretion of acid was in correspondence to the histological condition. In two cases out of 37 with atrophic gastric mucosa diverging results were found. After maximal stimulation with histamine chloride and pentagastrine one out of two cases with histologically intact mucosa showed normochlorhydria after seven days, whereas the second case remained achlorhydric. These results must be interpreted as functional achlorhydria. Submaximal stimulation of gastric secretion as it is practised today does not allow corresponding consequences concerning the morphological condition of the gastric mucosa. Discrepant results are found especially in histologically normal mucosa. There is more congruence in atrophic gastric mucosa.

Background and purpose Our aim was to evaluate the available evidence for pharmacological treatment of acute Lyme neuroborreliosis as a basis for evidence-based clinical recommendations in a systematic review. Methods A systematic literature search of Medline, EMBASE, the Cochrane Library and three trial registries was performed. Randomized controlled trials (RCTs) and non-randomized studies (NRS) were evaluated. Risk of bias was assessed using the Cochrane risk of bias tools. The primary outcome was ‘residual neurological symptoms’ whilst the secondary outcomes were disability, quality of life, pain, fatigue, depression, cognition, sleep, adverse events and cerebrospinal fluid pleocytosis. The quality of the evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. Results After screening 5779 records, eight RCTs and eight NRS were included. Risk of bias was generally high. No statistically significant difference was found between doxycycline and beta-lactam antibiotics in a meta-analysis regarding residual neurological symptoms at 4–12 months [risk ratio (RR) 1.27, 95% confidence interval (CI) 0.98–1.63, P = 0.07] or adverse events (RR 0.82, 95% CI 0.54–1.25, P = 0.35). Significantly fewer neurological symptoms for cefotaxime compared with penicillin were found (RR 1.81, 95% CI 1.10–2.97, P = 0.02). Adverse events were significantly fewer for penicillin (RR 0.56, 95% CI 0.38–0.84, P = 0.005). Conclusions Evidence regarding pharmacological treatment of acute Lyme neuroborreliosis is scarce and therefore insufficient to recommend preference of beta-lactam antibiotics over doxycycline or vice versa. However, due to considerable imprecision, relevant differences between treatments cannot be excluded. No evidence suggesting benefits of extended antibiotic treatments could be identified. Further well-designed trials are needed. Individual treatment decisions should address patients' preferences and individual conditions like prior allergic reactions.
