Sepsis incidence, suspicion, prediction and mortality in emergency medical services: a cohort study related to the current international sepsis guideline.

PURPOSE: Sepsis suspicion by Emergency Medical Services (EMS) is associated with improved patient outcomes. This study assessed sepsis incidence and recognition by EMS and analyzed which of the screening tools recommended by the Surviving Sepsis Campaign best facilitates sepsis prediction. METHODS: Retrospective cohort study of claims data from health insurances (n = 221,429 EMS cases), and paramedics' and emergency physicians' EMS documentation (n = 110,419); analyzed outcomes were: sepsis incidence and case fatality compared to stroke and myocardial infarction, the extent of documentation for screening-relevant variables and sepsis suspicion, tools' intersections for screening positive in identical EMS cases and their predictive ability for an inpatient sepsis diagnosis. RESULTS: Incidence of sepsis (1.6%) was similar to myocardial infarction (2.6%) and stroke (2.7%); however, 30-day case fatality rate was almost threefold higher (31.7% vs. 13.4%; 11.8%). Complete vital sign documentation was achieved in 8.2% of all cases. Paramedics never, emergency physicians rarely (0.1%) documented a sepsis suspicion, respectively septic shock. NEWS2 had the highest sensitivity (73.1%; Specificity:81.6%) compared to qSOFA (23.1%; Sp:96.6%), SIRS (28.2%; Sp:94.3%) and MEWS (48.7%; Sp:88.1%). Depending on the tool, 3.7% to 19.4% of all cases screened positive; only 0.8% in all tools simultaneously. CONCLUSION: Incidence and mortality underline the need for better sepsis awareness, documentation of vital signs and use of screening tools. Guidelines may omit MEWS and SIRS as recommendations for prehospital providers since they were inferior in all accuracy measures. Though no tool performed ideally, NEWS2 qualifies as the best tool to predict the highest proportion of septic patients and to rule out cases that are likely non-septic.

"We never lived together either": Couples' housing (re-) arrangements in later life.

Social gerontology mainly addresses couples' housing arrangements in later life by focusing on partner's care, related adaptations in place, and changing role expectations within the couple relationship. Thereby, the resulting image does not fully represent today's diversity of couples' housing arrangements. This article considers housing arrangement and relationship orientation of older couples as entangled in social practice, providing a broader perspective on the diversity and dynamics of couples living arrangements in later life. In a qualitative study, we conducted joint in-depth interviews with ten couples from Germany aged 58 to 88 years. Couples talked about their shared biography and living together today. Data were merged with fieldnotes on housing constellations and analyzed following the documentary method. Couples co-constitute living together by using space in different ways. We found three relationship orientations of couples corresponding to practices of couples' housing arrangements: balancing physical and emotional presence by negotiating shared space, exploring presence by having a third common place, and reducing presence by separate housing. These orientation types which are linked with spatial (re-) arrangements reveal positioning to housing preferences in past relationships and point to societal concepts of coupledom as regards housing in later life. Space gives options for both being apart from and feeling close to the partner, partially at the same time. Diversity and dynamics of housing arrangements correspond to diversified and altering relationship orientations in later life. Considering couples' housing arrangements in later life as mutually constitutive broadens the options to examine the meaning of space in aging together. Moreover, this perspective can be combined with a critical approach towards stereotypical (hetero-) normative biases in research.

Evaluation of a Digital Decision Support System to Integrate Type 2 Diabetes Mellitus and Periodontitis Care: Case-Vignette Study in Simulated Environments.

BACKGROUND: As highlighted by the recent World Health Organization Oral Health Resolution, there is an urgent need to better integrate primary and oral health care. Despite evidence and guidelines substantiating the relevance of integrating type 2 diabetes mellitus (T2DM) and periodontitis care, the fragmentation of primary and oral health care persists. OBJECTIVE: This paper reports on the evaluation of a prototype digital decision support system (DSS) that was developed to enhance the integration of T2DM and periodontitis care. METHODS: The effects of the prototype DSS were assessed in web-based simulated environments, using 2 different sets of case vignettes in combination with evaluation surveys among 202 general dental practitioners (GDPs) and 206 general practitioners (GPs). Each participant evaluated 3 vignettes, one of which, chosen at random, was assisted by the DSS. Logistic regression analyses were conducted at the participant and case levels. RESULTS: Under DSS assistance, GPs had 8.3 (95% CI 4.32-16.03) times higher odds of recommending a GDP visit. There was no significant impact of DSS assistance on GP advice about common risk factors for T2DM and periodontal disease. GDPs had 4.3 (95% CI 2.08-9.04) times higher odds of recommending a GP visit, 1.6 (95% CI 1.03-2.33) times higher odds of giving advice on disease correlations, and 3.2 (95% CI 1.63-6.35) times higher odds of asking patients about their glycated hemoglobin value. CONCLUSIONS: The findings of this study provide a proof of concept for a digital DSS to integrate T2DM and periodontal care. Future updating and testing is warranted to continuously enhance the functionalities of the DSS in terms of interoperability with various types of data sources and diagnostic devices; incorporation of other (oral) health dimensions; application in various settings, including via telemedicine; and further customization of end-user interfaces.

Heterogeneous Preferences for Colorectal Cancer Screening in Germany: Results of a Discrete Choice Experiment.

OBJECTIVES: Colorectal cancer (CRC) screening tests differ in benefits, harms, and processes, making individual informed decisions preference based. The objective was to analyze the preferences of insurees in Germany for characteristics of CRC screening modalities. METHODS: A generic discrete choice experiment with 2-alternative choice sets and 6 attributes (CRC mortality, CRC incidence, complications, preparation, need for transportation, and follow-up; 3 levels each) depicting characteristics of fecal testing, sigmoidoscopy, and colonoscopy was generated. Participants completed 8 choice tasks. Internal validity was tested using a within-set dominated pair. Between June and October 2020, written questionnaires were sent to a stratified random sample (n = 5000) of 50-, 55-, and 60-year-old insurees of the AOK (Allgemeine Ortskrankenkasse) Lower Saxony, who had previously received an invitation to participate in the organized screening program including evidence-based information. Preferences were analyzed using conditional logit, mixed logit, and latent-class model. RESULTS: From 1282 questionnaires received (26% [1282 of 4945]), 1142 were included in the analysis. Approximately 42% of the respondents chose the dominated alternative in the internal validity test. Three heterogeneous preference classes were identified. Most important attributes were preparation (class 1; n = 505, 44%), CRC mortality (class 2; n = 347, 30%), and CRC incidence (class 3; n = 290, 25%). Contrary to a priori expectations, a higher effort was preferred for bowel cleansing (class 1) and accompaniment home (classes 1 and 2). CONCLUSION: Internal validity issues of choice data need further research and warrant attention in future discrete choice experiment surveys. The observed preference heterogeneity suggests different informational needs, although the underlying reasons remained unclear.

Attributes in stated preference elicitation studies on colorectal cancer screening and their relative importance for decision-making among screenees: a systematic review.

INTRODUCTION: The SIGMO study (Sigmoidoscopy as an evidence-based colorectal cancer screening test - a possible option?) examines screening eligible populations' preferences for colorectal cancer (CRC) screening in Germany using a discrete choice experiment (DCE). Attribute identification and selection are essential for the construction of choice tasks and should be evidence-based. As a part of the SIGMO study this systematic review provides an overview of attributes included in studies eliciting stated preferences for CRC screening tests and their relative importance for decision-making. METHODS: Systematic search (November 2021) for English-language studies published since January 2000 in PubMed, Embase, Web of Science, Biomedical Reference Collection: Corporate Edition, LIVIVO and PsycINFO. DCEs and conjoint analysis ranking or rating tasks on screening eligible populations' preferences for stool testing, sigmoidoscopy, and/or colonoscopy were included. Attributes were extracted and their relative importance was calculated and ranked. Risk of bias (RoB) of included studies was assessed using a modified GRADE (Grading of Recommendations Assessment, Development and Evaluation) approach. Study selection and RoB rating were carried out independently by two reviewers. Data were extracted by one reviewer and checked by another one. RESULTS: A total of 23 publications on 22 studies were included. Overall RoB was rated as serious/critical for 21 studies and as moderate for 2 studies. Main reasons for high RoB were non-random sampling, low response rates, lack of non-responder analyses, and, to a lesser extent, weaknesses in the measurement instrument and data analysis. Extracted attributes (n = 120) referred to procedure-related characteristics (n = 42; 35%), structural characteristics of health care (n = 24; 20%), test characteristics (n = 23; 19%), harms (n = 16; 13%), benefits (n = 13; 11%), and level of evidence (n = 2; 2%). Most important attributes were reduction in CRC mortality (and incidence) (n = 7), test sensitivity (n = 7), out-of-pocket costs (n = 4), procedure (n = 3), and frequency (n = 2). CONCLUSIONS: Health preference studies on CRC were found to have a high RoB. The composition of choice tasks revealed a lack of attributes on patient-important outcomes (like incidence reduction), while attributes not considered relevant for individual screening decisions (like sensitivity) were frequently used. Future studies eliciting stated preferences in cancer screening should apply the principles of informed decision-making in attribute identification and selection.

Feasibility assessment of patient-controlled EEG home-monitoring: More results from the HOMEONE study.

OBJECTIVE: The feasibility phase of the HOME (Home-Monitoing and Education) project aims to show the practical feasibility of Electroencephalography (EEG)home-monitoring using a patient-controlled mobile system. Its objective is to assess the potential diagnostic and therapeutic yields of home-monitoring compared to conventional healthcare. METHODS: 16 office-based practitioners chose 97 patients and recorded standard 20-minute EEGs using conventional recorders. After training, the same patients used a patient-controlled mobile dry electrode EEG system in their home environment. The practitioners in charge and two additional raters assessed all recordings. We conducted inter-rater and intra-rater comparisons between the diagnostic findings. RESULTS: 89 patients successfully conducted home-monitoring recordings. The intra-rater comparison results for the diagnostic findings of the conventional recordings and the patient-made recordings show a fair Cohen's kappa value (0.21). Additionally, we documented a change of patient management in 9 cases. CONCLUSIONS: The feasibility of EEG home-monitoring using a patient-controlled device is confirmed. The yield of EEG home-monitoring comprises information that can influence patient management. SIGNIFICANCE: Patient-controlled EEG home-monitoring is feasible as part of routine care for neurological outpatients as its technical efficacy and practical feasibility are shown and significantly positive effects on patient management are evidenced.

Apart from the Medical Complaints, Why do Patients Use Emergency Medical Services? Results of a Patient Survey.

INTRODUCTION: Many countries face an increased use of emergency medical services (EMS) with a decreasing percentage of life-threatening complaints. Though there is a broad discussion among experts about the cause, patients' self-perceived, non-medical reasons for using EMS remain largely unknown. METHODS: The written survey included EMS patients who had≥1 case of prehospital emergency care in 2016. Four German health insurance companies sent out postal questionnaires to 1312 insured patients. The response rate was 20%; 254 questionnaires were eligible for descriptive and interferential analyses (t-tests, chi2-tests, logistic models). RESULTS: The majority of respondents indicated that their EMS use was due to an emergency or someone else's decision (≥84%; multiple checks allowed); 56% gave need for a quick transport as a reason. Other frequently stated reasons addressed the health care system (e. g., complaints outside of physicians' opening hours) and insecurity/anxiety about one's state of health (>45% of the respondents). "Social factors" were similarly important (e. g., 42% affirming, "No one could give me a ride to the emergency department or doctor's office."). Every fifth person had contact with other emergency care providers prior to EMS use. Respondents negating an emergency as a reason were less likely to confirm wanting immediate medical care on site or quick transports compared to those affirming an emergency. Patients using EMS at night more often denied having an emergency compared to patients with access to care during the day. CONCLUSION: The study identified a bundle of reasons leading to EMS use apart from medical complaints. Attempts for needs-oriented EMS use should essentially include optimization of the health care and social support system and measures to reduce patients' insecurity.

Public Preferences for Exit Strategies From COVID-19 Lockdown in Germany-A Discrete Choice Experiment.

Objectives: To decrease the rapid growth of SARS-CoV-2 in Germany, a stepped lockdown was conducted. Acceptance and compliance regarding entering and exiting lockdown measures are key for their success. The aim of the present study was to analyse the population's preferences for exiting lockdown measures. Methods: To evaluate population's preferences and identify trade-offs between different exit strategies, a discrete choice experiment was conducted on 28-29 April (n = 1,020). Overall, six attributes and 16 choice sets (fractional-factorial design) without an opt-out were chosen. Conditional logit and latent class models were conducted. Results: Most attributes proved to be significant. Two attributes dominated all others: Avoiding a mandatory tracing app, and providing sufficient intensive care capacities. Preventing a high long-term unemployment rate and avoiding the isolation of persons aged 70+, were relevant, though utilities were comparatively lower. We identified subgroups (elderly persons and persons with school children) with different utilities, which indicates specific attributes affecting them dissimilarly. Conclusions: The population prefers cautious re-opening strategies and is at least sceptical about the adoption of severe protection measures. Government should balance interests between subgroups.

Finding common (research) ground between general practitioners and neuroscientists: the vital role of knowledge circulation in closing the evidence-to-practice gap.

BACKGROUND: It may take 15 years or longer before research evidence is integrated into clinical practice. This evidence-to-practice gap has deleterious effects on patients as well as research and clinical processes. Bringing clinical knowledge into the research process, however, has the potential to close the evidence-to-practice gap. The NEUROTRANS-Project attempts to bring research and practice together by focusing on two groups that usually operate separately in their communities: general practitioners and neuroscientists. Although both groups focus on dementia as an area of work, they do so in different contexts and without opportunities to share their expertise. Finding new treatment pathways for patients with dementia will require an equal knowledge exchange among researchers and clinicians along with the integration of that knowledge into research processes, so that both groups will benefit from the expertise of the other. METHODS: The NEUROTRANS-Project uses a qualitative, multi-stage research design to explore how neuroscientists and general practitioners (GPs) approach dementia. Using a grounded theory methodology, it analyzes semi-structured interviews, case vignettes, focus groups with GPs in Saxony-Anhalt, Germany, and informal conversations with, and observations of, neuroscientists from the German Center for Neurodegenerative Diseases in Magdeburg. RESULTS: The NEUROTRANS-Project identified a clear division of labor between two highly specialized professional groups. Neuroscientists focus abstractly on nosology whereas general practitioners tend to patient care following a hermeneutic approach integrating the patients' perspective of illness. These different approaches to dementia create a barrier to constructive dialogue and the capacity of these groups to do research together with a common aim. Additionally, the broader system of research funding and health care within which the two groups operate reinforces their divide thereby limiting joint research capacity. CONCLUSIONS: Overcoming barriers to research collaboration between general practitioners and neuroscientists requires a shift in perspective in which both groups actively engage with the other's viewpoints to facilitate knowledge circulation (KC). Bringing 'art into science and science into art', i.e. amalgamating the hermeneutic approach with the perspective of nosology, is the first step in developing joint research agendas that have the potential to close the evidence-to-practice gap.

How do specialist surgeons treat the atrophic tooth gap? A vignette-based study among maxillofacial and oral surgeons.

BACKGROUND: There is little information available regarding the decision-making process of clinicians, especially in the choice of therapy for a severely atrophic tooth gap. The aim of this research was to use case vignettes to determine the influence of possible factors on the decision making of maxillofacial and oral surgeons. METHODS: A total of 250 maxillofacial (MFS) and oral (OS) surgeons in southern Germany were surveyed for atrophic single- or multiple-tooth gap with the help of case vignettes. The influence of different determinants on the therapy decision was investigated. Two case vignettes were designed for this purpose: vignette 1 with determinants "patient age" and "endocarditis prophylaxis" and vignette 2 with determinants "anxiety" and "bisphosphonate therapy". Furthermore, the specialist designation was assessed for both. The options available to achieve a sufficient implant site were "bone split", "bone block", "augmentation with bone substitute material" and "bone resection". Therapy was either recommended or rejected based on principle. RESULTS: A total of 117 participants returned the questionnaire: 68 (58%) were OS and 49 (42%) MFS. "Patient age" and "patient anxiety" were not significantly associated with any therapy decision. However, required "endocarditis prophylaxis" led to significantly higher refusal rates for "bone split", "bone block" and "bone replacement material" and to higher rates of general refusal of a therapy. "Bisphosphonate therapy" was significantly associated with general refusal of therapy, but with no significant correlation with different therapy options. In vignette 1, OS refused therapy significantly more often than MFS, though there was no association with the specialist designation for other therapy modalities. In vignette 2, specialty was not significantly associated with the therapy decision. CONCLUSION: "Patient age" as well as "patient anxiety" appear to have no or little influence on the treatment decision for severely atrophic single- or multiple-tooth gap by specialist surgeons. Surgeons more often refuse treatment for patients with endocarditis prophylaxis and bisphosphonate therapy.

Harms and Benefits of Cancer Screening.

In recommending and offering screening, health services make a health claim ('it's good for you'). This article considers ethical aspects of establishing the case for cancer screening, building a service programme, monitoring its operation, improving its quality and integrating it with medical progress. The value of (first) screening is derived as a function of key parameters: prevalence of the target lesion in the detectable pre-clinical phase, the validity of the test and the respective net utilities or values attributed to four health states-true positives, false positives, false negatives and true negatives. Decision makers as diverse as public regulatory agencies, medical associations, health insurance funds or individual screenees can legitimately come up with different values even when presented with the same evidence base. The main intended benefit of screening is the reduction of cause-specific mortality. All-cause mortality is not measurably affected. Overdiagnosis and false-positive tests with their sequelae are the main harms. Harms and benefits accrue to distinct individuals. Hence the health claim is an invitation to a lottery with benefits for few and harms to many, a violation of the non-maleficence principle. While a public decision maker may still propose a justified screening programme, respect for individual rights and values requires preference-sensitive, autonomy-enhancing educational materials-even at the expense of programme effectiveness. Opt-in recommendations and more 'consumer-oriented' qualitative research are needed.

Decision-Making in Implantology-A Cross-Sectional Vignette-Based Study to Determine Clinical Treatment Routines for the Edentulous Atrophic Mandible.

This cross-sectional study aimed to investigate the influence of possible factors in the patient history on decision making in the therapy for a severely atrophied edentulous mandible. A vignette-based survey among 250 maxillofacial and oral surgeons was conducted. Determinants that could influence the therapy decision were patient age, smoking, fear of surgery, and radiotherapy in the head and neck area (the implant region is not in the direct radiation area). To achieve a suitable implant site, the options offered to the surgeons were bone split, bone block, augmentation with bone substitute material, and bone resection. There also was the option of rejecting any therapy. The response rate was 47%. Patient age, radiotherapy, and fear of surgery did not influence the approval of a therapy. Smoking was associated with a significantly lower endorsement of a treatment. Resection was preferred by a large majority to all other forms of therapy, regardless of the four determinants. Surgeons tend to refrain from bone block transplants in older patients. In summary, it can be said that, of the four determinants, only smoking influenced treatment refusal. Bone resection is the preferred therapy independent of all determinants.

General populations' preferences for colorectal cancer screening: rationale and protocol for the discrete choice experiment in the SIGMO study.

INTRODUCTION: In Germany, the organised colorectal cancer (CRC) screening programme includes the immunologic faecal occult blood test and colonoscopy. The sigmoidoscopy is recommended for individuals rejecting colonoscopy but is not included into the screening programme. To examine whether the evidence based sigmoidoscopy should be additionally offered, the first objective of this study is to evaluate the demand for sigmoidoscopy by analysing the German general populations' preferences for CRC screening. METHODS AND ANALYSIS: Preference data will be collected using a discrete choice experiment (DCE). Identification and selection of the attributes and their levels will be supported by evidence resulting from a systematic literature search and focus groups. An efficient, fractional factorial choice design will be generated. In a cross-sectional study, the DCE will be administered as a written questionnaire to a random sample of 4000 members of the statutory health insurance company in Lower Saxony (AOK Lower Saxony). Insured persons 50-60 years of age without CRC or a chronic inflammatory bowel disease will be eligible. The collected choice data will be analysed by conducting a conditional logit regression model and latent class models. ETHICS AND DISSEMINATION: Ethical approval for this study was obtained from the Ethics Committee of Hannover Medical School (reference number 8671_BO_K_2019). The study results will be disseminated via conference presentations, publications in peer-reviewed journals and, to participants, the membership magazine of the AOK Lower Saxony. TRIAL REGISTRATION NUMBER: DRKS00019010.

Pre-implantological treatment routines for alveolar ridge atrophy - an investigation among maxillofacial and oral surgeons in southern Germany.

BACKGROUND: It is not well-known which pre-implantological procedures are preferred by maxillofacial (MFS) and oral surgeons (OS) for the narrow atrophic alveolar ridge under practice based conditions and, if different training paths in surgery lead to other pre-implantological techniques being preferred. This study aims to identify which procedures are preferred by the respective specialists in which indication. METHODS: A questionnaire was sent to a total of 300 MFS and OS in southern Germany. The questionnaire examined pre-implantological procedures (bone block, bone grafting material and/or particulate autogenous bone, titanium mesh, bone split, resection) in the edentulous severely atrophic mandible and in the severely atrophic single-tooth gap. Kendall's Tau-b test was used for statistical analyses. RESULTS: One hundred seventeen participants returned the questionnaire. 68 (58%) were OS and 49 (42%) were MFS. In the edentulous mandible, bone substitute material and resection were most preferred by both specialists. Bone blocks were statistically significantly more frequently associated with MFS and bone substitute materials with OS. Bone split was more frequently used in the atrophic single tooth gap than in the edentulous mandible. OS preferred bone blocks in the single tooth gap more often than in the edentulous mandible. MFS and OS preferred resection in the edentulous mandible significantly more frequently than in the single tooth gap. CONCLUSIONS: MFS in general prefer more invasive pre-implantological therapies with the same initial diagnosis than OS, which seems to be attributed to different training paths.

The Effects of Intensive Versus Routine Treatment in Patients with Acute Kidney Injury.

BACKGROUND: In patients with acute kidney injury (AKI), specialized treatment-initiated in response to an early-warning system- may be beneficial compared with routine treatment. METHOD: To explore effect estimators in a pilot trial (DRKS00010530), patients with AKI on regular wards of a university hospital were treated either in the usual way (control group) or more intensively (intervention group). The subjects were allotted randomly to the two treatment groups. The more intensive treatment consisted of an early warning system for a rise in the serum creatinine concentration, immediate consultation of a specialist, and the issuance of a patient kidney passport. The primary endpoint was recovery of renal function after AKI during the index hospitalization. Renal complications and process indicators were the secondary endpoints. RESULTS: The proportion of patients whose renal function returned to baseline after AKI was 50% in the intervention group (N = 26) and 42% in the control group (N = 26) (odds ratio 1.4, 95% confidence interval [0.5; 4.0], p = 0.58). The calculated glomerular filtration rate went down, from hospital admission to discharge, by 3 mL/min/1.73 m2 (1st-3rd quartile: [6; -20]) in the intervention group and by 13 mL/min/1.73 m2 in the control group (1st-3rd quartile: [0; -25]; p = 0.09). Complications of AKI such as hyperkalemia, pulmonary edema, and renal acidosis were rarer in the intervention group (15% versus 39%; p = 0.03). In the intervention group, compared with the control group, the cause of AKI was identified more frequently (27% versus 4%; p = 0.05); drugs with relevance to the kidney were discontinued more frequently (65% versus 31%; p = 0.01); and the diagnosis of AKI was more frequently documented in the patient's chart (58% versus 37%; p = 0.03). CONCLUSION: Specialized consultations supported by an early warning system for AKI seem to be beneficial for patients. The findings of this pilot trial should be verified in larger-scale randomized controlled trials.

[Manfred Pflanz (1923-1980), Health Services Researcher: his Early Contribution to the Medical Care Pattern of Appendectomy]. / Manfred Pflanz (1923­1980), Versorgungsforscher ­ sein früher Beitrag zur Versorgungsepidemiologie der Appendektomie.

This article is a reminder of an early example of health services research and quality assurance in Germany. The occasion for this was the 50th anniversary of the opening of the Institute of Social Medicine and Epidemiology at Hannover Medical School in 1968. The founding director of the institute, Prof. Dr. med. Manfred Pflanz, a board-certified internist, had gained reputation by publishing on psychosomatic and medico-social issues. In 1971, Sigrid Lichtner, a doctoral student, and Pflanz published a paper on the epidemiology and medical care pattern of appendectomy [1]. In the late 1960s certified appendicitis mortality in the Federal Republic of Germany used to be 3 times higher than in comparable countries. A regional analysis of all appendectomies in Hannover discovered further "odd" findings such as a weekly profile of operations not in line with an acute emergency condition and clear social as well as regional differences in the appendectomy rate. The most probable reason why the mortality from appendicitis was 3 times higher in the Federal Republic than in any other country, the authors conjectured, was that appendectomy was performed 3 times more frequently than elsewhere - questioning the doctrine of early surgical intervention in suspected appendicitis. Since then, management of appendicitis has changed, quality assurance has been implemented, evidence broadened, laparoscopic and non-operative treatment evaluated in RCTs. Appendicitis mortality has continued to decline with an acceleration of the falling trend in the early 1970s. Absolute numbers of deaths are now very low. Numbers of appendectomies are declining. In this respect, health services have become more effective and efficient.

Health care utilisation and medication one year after myocardial infarction in Germany - a claims data analysis.

BACKGROUND: After myocardial infarction, guidelines recommend pharmaceutical treatment with a combination of five different types of drugs for prevention in patients. However, studies from different countries have shown that this goal is not achieved in many patients. The aim of this study was to assess both healthcare and prescribed pharmaceutical treatment in the fourth quarter after index myocardial infarction. METHODS: We conducted a claims data analysis with the data of patients who had had a myocardial infarction in the years 2013 or 2014, using information from the largest German health insurance fund ('AOK'). We analysed contact with physicians, hospital care and actual prescriptions for medication recommended in international guidelines, referring to beta-blockers, ACE inhibitors or angiotensin II receptor blockers, P2Y12-antiplatelet agents, acetylsalicylic acid and statins, one year after myocardial infarction. Analysis was stratified by age and sex, compared between patient groups and over time. RESULTS: We identified 2352 patients who had survived myocardial infarction. Some 96.9% of these participants had at least one contact with their general practitioner (GP) one year after myocardial infarction, 22.8% contacted a cardiologist and 19.7% were hospitalised. Prescription rates range from 37.8% for acetylsalicylic acid to 70.4% for ACE inhibitors. However, only 24.1% received statins, beta-blockers, ACE inhibitors and an antiplatelet drug simultaneously. Prescription of recommended drugs after myocardial infarction decreased steadily over time. DISCUSSION: Long-term medical prevention after myocardial infarction is improvable. GPs should take care of the pharmaceutical prevention after myocardial infarction as they are the physicians seen most intensively in this period.

What understanding of economics do medical students have?

Introduction: Economic topics appear in the medical studies curriculum at different times. Despite socio-political relevance, there is hardly any information about the degree of understanding that medical students have of "economics in medicine". The present study addresses the questions: What understanding of "economics in medicine" do medical students have before the start of the Practical Year? To what extent is economic teaching content understood as "economization" from outside the profession? Method: Magdeburg medical students in the 5th year of study, who participated in preparatory seminars for the Practical Year (PY) in 2014 and 2015 (60 participants each), assessed the relevance of various seminar topics four months prior to the start of the semester. On the basis of a three-stage qualitative-reconstructive partial evaluation, students' economic understanding is explored through secondary analysis: deductive derivation of the analysis units; integrative basic method ("segmentation", "micro-linguistic detailed analysis", "central theme"); development of a theoretical model by placing the central themes in context following Grounded Theory. Results: Based on the theory, 19 free-text answers with economic reference were identified from the total of all free-text answers. Each answer was assigned to at least one of a total of six themes of the students' understanding of economics: de-professionalizing economization, deciding and working economically, ambivalent requirements for efficiency and equity, the doctor as an entrepreneur, economics as relevant learning content, PY as a conflict-laden setting for economized working and learning. The theoretical model contains social, praxeological and professional references, which can themselves be ambivalent and conflicting. Conclusion: Despite their critical attitude, the surveyed medical students are neither hostile to economics nor do they regard economics in medicine as a taboo subject. Economic learning content is recognized as relevant. Educational formats that tackle the tension between patient and system orientation in a problem-oriented manner can be a productive setting for economic reflection.
