Analysis of the Results of Sonographic Screening Examinations According to the Maternity Guidelines Before and After the Introduction of the Extended Basic Screening (IIb Screening) in Hesse.

AIM OF THE STUDY: The aim of the study is to examine the detection rates of malformations before and after the introduction of extended basic screening in Hesse by the Federal Joint Committee (Gemeinsamer Bundesausschuss, GQH) on July 1, 2013. METHOD: This is a retrospective, mainly exploratory data analysis of quality assurance data from the Office for Quality Assurance in Hesse (GQH). The data was collected in the period from January 1, 2010 to December 31, 2016 in the obstetric departments of the Hessian hospitals using documentation forms. The classification and evaluation of the diagnoses is based on ICD-10-GM-2019. RESULTS: At least one malformation is present in 0.7% of the cases. With a share of 30.0%, most of the congenital malformations are from the musculoskeletal system. 12.2% of the malformations come from the facial cleft, closely followed by malformations of the circulatory system with 11.3%. The highest prenatal detection rate (PDR) is found in congenital malformations of the nervous system at 56.8%. The lowest PDR is found in those of the genital organs with 2.1%. The PDR of cardiovascular malformations is 32.9%. Overall, a PDR of 25.2% is achieved. There was no change in the number of prenatal malformation diagnoses after the introduction of extended basic ultrasound. The distribution of malformation diagnoses not detected prenatally to the organ systems also has not changed after the introduction. CONCLUSION: The introduction of extended basic ultrasound did not bring the desired improvement with regard to the PDR in Hesse. Alternative approaches should be considered.

[Specialization of Acute Stroke Care in Germany: Structural Changes During 2006-2017]. / Spezialisierung der Schlaganfallversorgung in Deutschland: Strukturveränderungen im Zeitraum von 2006­2017.

HINTERGRUND: Um die Schlaganfallversorgung zu optimieren, wurden in Deutschland in den letzten Jahren verschiedene qualitätsfördernde Maßnahmen (qfM) in regional unterschiedlichem Maß eingeführt. Ob sich diese Maßnahmen über die Jahre flächendeckend etabliert haben, ist unklar. METHODE: Für die strukturbezogenen Analysen der Schlaganfallversorgung in Deutschland wurden alle relevanten dokumentierten Schlaganfälle (ICD-10) aus den Qualitätsberichten (QB) deutscher Krankenhäuser und eine repräsentative Stichprobe von Krankenversicherungsdaten (AOK) im Zeitraum von 2006 (QB)/2007 (AOK) bis 2017 verwendet. Diese Informationen wurden u. a. durch Angaben zu zertifizierten Stroke Units der Deutschen Schlaganfall-Gesellschaft (DSG) und Daten zur Führung von regionalen Schlaganfall-Registern der Arbeitsgemeinschaft Deutschsprachiger Schlaganfall-Register (ADSR) ergänzt. Zur Verfolgung der Veränderungen des Versor-gungsgeschehens im deutschen Bundesgebiet wurden die Daten mit geografischen Daten (Bundesamt für Kartographie und Geodäsie) verknüpft. Es erfolgten univariate Analysen der Daten und eine Trend-Analyse der verschiedenen qfM im Jahresverlauf (Konkordanzkoeffizient nach Kendall). ERGEBNISSE: Die QB Analysen zeigten einen Anstieg kodierter Schlaganfälle in Krankenhäusern mit qfM um 14-20%. In 2006 wurden 80% der Schlaganfälle (QB) in einem Krankenhaus mit min. einer qfM kodiert, in 2017 95%. Diese Entwicklungen spiegelten sich auch in den AOK-Routinedaten wider, wobei in 2007 89% und in 2017 97% der Patient:innen unter mindestens einer qfM behandelt wurden. Dabei waren in 2007 bei 55% der behandelnden Krankenhäuser qfM vorhanden, in 2017 bei 72%. SCHLUSSFOLGERUNG: Patient:innen werden inzwischen signifikant häufiger in Krankenhäusern mit Spezialisierung auf die Schlaganfallversorgung behandelt. Auch die verschiedenen qfM haben sich im Laufe der Jahre im gesamten Bundesgebet verbreitet, jedoch existieren noch Versorgungslücken, die geschlossen werden sollten, damit in Zukunft alle Patient:innen qualitativ hochwertig behandelt werden können. BACKGROUND: In order to optimize stroke care, various quality-enhancing measures (qfM) have been introduced in Germany in recent years to varying degrees across regions, with the aim of achieving the best possible quality of care. It is unclear whether these measures have become established nationwide over the years. METHOD: For the structural analyses of stroke care in Germany, all relevant documented strokes (ICD-10) from the quality reports (QB) of German hospitals and a representative sample of health insurance data (AOK) for the period from 2006 (QB)/2007 (AOK) to 2017 were used. This information was supplemented by data on certified stroke units from the German Stroke Society (DSG) and data on the maintenance of regional stroke registries from the Working Group of German-Speaking Stroke Registers (ADSR), among others. To track changes in patterns of care in Germany, the data were linked with geographic data (Federal Agency for Cartography and Geodesy). Univariate analyses of the data and a trend analysis of the different qfM over the year (Kendall concordance coefficient) were performed. RESULTS: The analyses (QB) showed an increase in coded strokes in hospitals with qfM between 14-20%. In 2006, 80% of strokes (QB) were coded in hospitals with at least one qfM and 95% in 2017. Comparing years, AOK data showed similar trends: in 2007, 89% of patients were treated in hospitals with at least one qfM and 97% in 2017. In 2007, 55% of treating hospitals had qfM and 72% in 2017. CONCLUSION: Meanwhile, patients are more often treated in hospitals that specialise in stroke care. In addition, the various qfM have spread across the nation over the years, but there are still gaps in care that should be addressed to ensure quality care for all patients in the future.

Associations between structure- and process-orientated measures and stroke long term mortality - an observational study based on routine data.

OBJECTIVES: Various measures are used to improve the quality of stroke care. In Germany, these include concentrating treatment in specialized facilities (stroke units), mandatory quality comparisons of hospitals in some German states, and treatment according to prespecified structure and process specifications (neurological complex treatment 8-981 or 8-98b). These measures have previously only been analyzed individually and regarding short-term patient outcomes. This study analyzes these measures in combination, considering patients' comorbidities as well as stroke severity in a longitudinal perspective. MATERIALS/METHODS: Analyses were based on data from 243,415 insurees of Germany's biggest health insurance (AOK) admitted to hospitals between 2007 and 2017 with cerebral infarction. Mortality risk was calculated using Cox regressions adjusted for various covariates. Kaplan-Meier analyses were differentiated by treatment site (stroke unit/external quality assurance/ Federal State Consortium of Quality Assurance Hesse - LAGQH) were performed, followed by log-rank tests and p-value adjustment. Trend analyses were performed for treatment types in combination with treatment sites. RESULTS: All analyses showed significant advantages for patients who received Neurological Complex Treatment, especially when the treatment was performed under external quality assurance conditions and/or in stroke units. There was an increasing frequency of specialized stroke treatment. CONCLUSIONS: Quality-enhancing structures and processes are associated with a lower mortality risk after stroke. There appears to be evidence of a cascading benefit from the implementation of neurological complex treatment, external quality assurance, and ultimately, stroke units. Consecutively, care should be concentrated in hospitals that meet these specifications. However, since measures are often applied in combination, it remains unclear which specific measures are crucial for patient outcome.

Long-term outcomes of stroke unit care in older stroke patients: a retrospective cohort study.

BACKGROUND: older patients are less frequently treated in stroke units (SUs). Clinicians do not seem convinced that older patients benefit from specialised treatment in SU similarly to younger patients. OBJECTIVE: our study aimed to compare older patients' long-term outcomes with and without SU treatment. METHODS: this study used routinely collected health data of 232,447 patients admitted to hospitals in Germany between 2007 and 2017 who were diagnosed with ischaemic stroke (ICD 10 I63). The sample included 29,885 patients aged ≥90 years. The outcomes analysed were 10-, 30- and 90-day, and 1-, 3- and 5-year mortality and the combinations of death or recurrence, inpatient treatment and increase in long-term care needs. Bivariate chi-square tests and multivariable logistic regression analyses were used, adjusting for the covariates age, sex, co-morbidity, long-term care needs before stroke and socioeconomic status of the patients' region of origin. RESULTS: between 2007 and 2017, 57.1% of patients aged <90 years and 49.6% of those aged ≥90 years were treated in a SU. The 1-year mortality rate of ≥90-year-olds was 56.9 and 61.9% with and without SU treatment, respectively. The multivariable-adjusted risk of death in ≥90-year-olds with SU treatment was odds ratio (OR) = 0.67 (95% confidence interval [CI] = 0.62-0.73) 10 days after the initial event and OR = 0.76 (95% CI = 0.71-0.82) 3 years after stroke. CONCLUSIONS: even very old patients with stroke benefit from SU treatment in the short and long term. Therefore, SU treatment should be the norm even in older patients.

Association Between Adherence to Quality Indicators and 7-Day In-Hospital Mortality After Acute Ischemic Stroke.

BACKGROUND AND PURPOSE: Quality indicators (QI) are an accepted tool to measure performance of hospitals in routine care. We investigated the association between quality of acute stroke care defined by overall adherence to evidence-based QI and early outcome in German acute care hospitals. METHODS: Patients with ischemic stroke admitted to one of the hospitals cooperating within the ADSR (German Stroke Register Study Group) were analyzed. The ADSR is a voluntary network of 9 regional stroke registers monitoring quality of acute stroke care across 736 hospitals in Germany. Quality of stroke care was defined by adherence to 11 evidence-based indicators of early processes of stroke care. The correlation between overall adherence to QI with outcome was investigated by assessing the association between 7-day in-hospital mortality with the proportion of QI fulfilled from the total number of QI the individual patient was eligible for. Generalized linear mixed model analysis was performed adjusted for the variables age, sex, National Institutes of Health Stroke Scale and living will and as random effect for the variable hospital. RESULTS: Between 2015 and 2016, 388 012 patients with ischemic stroke were reported (median age 76 years, 52.4% male). Adherence to distinct QI ranged between 41.0% (thrombolysis in eligible patients) and 95.2% (early physiotherapy). Seven-day in-hospital mortality was 3.4%. The overall proportion of QI fulfilled was median 90% (interquartile range, 75%-100%). In multivariable analysis, a linear association between overall adherence to QI and 7-day in-hospital-mortality was observed (odds ratio adherence <50% versus 100%, 12.7 [95% CI, 11.8-13.7]; P<0.001). CONCLUSIONS: Higher quality of care measured by adherence to a set of evidence-based process QI for the early phase of stroke treatment was associated with lower in-hospital mortality.

Variations in use of childbirth interventions in 13 high-income countries: A multinational cross-sectional study.

BACKGROUND: Variations in intervention rates, without subsequent reductions in adverse outcomes, can indicate overuse. We studied variations in and associations between commonly used childbirth interventions and adverse outcomes, adjusted for population characteristics. METHODS AND FINDINGS: In this multinational cross-sectional study, existing data on 4,729,307 singleton births at ≥37 weeks in 2013 from Finland, Sweden, Norway, Denmark, Iceland, Ireland, England, the Netherlands, Belgium, Germany (Hesse), Malta, the United States, and Chile were used to describe variations in childbirth interventions and outcomes. Numbers of births ranged from 3,987 for Iceland to 3,500,397 for the USA. Crude data were analysed in the Netherlands, or analysed data were shared with the principal investigator. Strict variable definitions were used and information on data quality was collected. Intervention rates were described for each country and stratified by parity. Uni- and multivariable analyses were performed, adjusted for population characteristics, and associations between rates of interventions, population characteristics, and outcomes were assessed using Spearman's rank correlation coefficients. Considerable intercountry variations were found for all interventions, despite adjustments for population characteristics. Adjustments for ethnicity and body mass index changed odds ratios for augmentation of labour and episiotomy. Largest variations were found for augmentation of labour, pain relief, episiotomy, instrumental birth, and cesarean section (CS). Percentages of births at ≥42 weeks varied from 0.1% to 6.7%. Rates among nulliparous versus multiparous women varied from 56% to 80% versus 51% to 82% for spontaneous onset of labour; 14% to 36% versus 8% to 28% for induction of labour; 3% to 13% versus 7% to 26% for prelabour CS; 16% to 48% versus 12% to 50% for overall CS; 22% to 71% versus 7% to 38% for augmentation of labour; 50% to 93% versus 25% to 86% for any intrapartum pain relief, 19% to 83% versus 10% to 64% for epidural anaesthesia; 6% to 68% versus 2% to 30% for episiotomy in vaginal births; 3% to 30% versus 1% to 7% for instrumental vaginal births; and 42% to 70% versus 50% to 84% for spontaneous vaginal births. Countries with higher rates of births at ≥42 weeks had higher rates of births with a spontaneous onset (rho = 0.82 for nulliparous/rho = 0.83 for multiparous women) and instrumental (rho = 0.67) and spontaneous (rho = 0.66) vaginal births among multiparous women and lower rates of induction of labour (rho = -0.71/-0.66), prelabour CS (rho = -0.61/-0.65), overall CS (rho = -0.61/-0.67), and episiotomy (multiparous: rho = -0.67). Variation in CS rates was mainly due to prelabour CS (rho = 0.96). Countries with higher rates of births with a spontaneous onset had lower rates of emergency CS (nulliparous: rho = -0.62) and higher rates of spontaneous vaginal births (multiparous: rho = 0.70). Prelabour and emergency CS were positively correlated (nulliparous: rho = 0.74). Higher rates of obstetric anal sphincter injury following vaginal birth were found in countries with higher rates of spontaneous birth (nulliparous: rho = 0.65). In countries with higher rates of epidural anaesthesia (nulliparous) and spontaneous births (multiparous), higher rates of Apgar score < 7 were found (rhos = 0.64). No statistically significant variation was found for perinatal mortality. Main limitations were varying quality of data and missing information. CONCLUSIONS: Considerable intercountry variations were found for all interventions, even after adjusting for population characteristics, indicating overuse of interventions in some countries. Multivariable analyses are essential when comparing intercountry rates. Implementation of evidence-based guidelines is crucial in optimising intervention use and improving quality of maternity care worldwide.

[Critical Outcome and Hypoxic Ischemic Encephalopathy - A quality Assurance Issue]. / Kritisches Outcome und Hypoxisch-Ischämische Enzephalopathie (HIE) ­ Ein Thema der Qualitätssicherung.

The study evaluates the predictive value of the critical status of a newborn as to the risk of developing hypoxic ischemic encephalopathy (HIE). METHODS: On the basis of the data set from the perinatal survey in Hesse, Germany, in the year 2016, including 52,122 live births (singleton, 37+0 GA), cases of critical newborns were identified. A conjoined analysis with the data set of the neonatal survey from the identical period provided the basis to evaluate the relationship to cases compromised by HIE. RESULTS: The incidence of cases with a critical outcome (n=11) and those with HIE (n=29) was low. The sensitivity of the status of the newborn for detecting a risk of HIE was 10.34%. The specificity was 99.98%. The positive predictive value was 27.35%. The negative predictive value was 99.95%. The detailed, confidential single-case analysis indicated the ability to avoid negative outcomes in about one third of cases with a critical status of the newborn (4/11) and HIE (9/29). DISCUSSION AND CONCLUSION: The likelihood of developing encephalopathy (HIE) increases after a critical outcome after birth. Intensified monitoring of these newborns is justified. A single-case analysis identifies the potential ways to improve perinatal outcomes. Measures of external quality assurance should integrate the analysis of both perinatal and neonatal surveys as a basis for quality management (QM).

[Is it Reasonable to Establish an Independently Managed Obstetric Unit in a Small Hospital and Does it Result in Measurable Changes in Quality of Maternity Care?] / Ist eine eigenständige Geburtshilfe in einem Haus der Grund- und Regelversorgung sinnvoll und führt sie zu messbaren Veränderungen in der Versorgung?

INTRODUCTION: An independently managed, specialty obstetric unit in a small hospital setting resulted in measurable changes in quality of maternity care. MATERIAL AND METHODS: We present obstetric data from a level I (basic care) hospital in Frankfurt, Germany. We compare data from the mandatory state register collected in 2013, when the obstetric unit was under single management with the gynaecology department, with data collected in 2016 after the establishment of independent obstetric unit and a specialised service. RESULTS: Between 2013 and 2016, the birth rate in our hospital increased by 46.4%, from 803 to 1176 births/year. CS rates decreased by 8.9%, from 34.9 to 26% (p<0.01). Operative vaginal delivery rates increased by 5.2 (p<0.01%). Transfer of neonates to NICU decreased from 5.6% to 3.1% (p<0.01). Other obstetric interventions also decreased, including induction of labour (10.1 to 9.4%, p=0.632) and rate of episiotomy (13.4 to 1.1%, p<0.01). Rates of severe fetal acidosis (p<0.05) increased from no events in 2013 to 2 events in 2016. There were non-significant reductions in planned caesarean section for primiparous women and repeat caesarean section. CONCLUSION: An independently managed, specialised obstetric unit separate from an Obstetric & Gynaecology Department previously under single management can lead to measurable changes and quality improvement in a short period of time.

Stroke unit care in germany: the german stroke registers study group (ADSR).

BACKGROUND: Factors influencing access to stroke unit (SU) care and data on quality of SU care in Germany are scarce. We investigated characteristics of patients directly admitted to a SU as well as patient-related and structural factors influencing adherence to predefined indicators of quality of acute stroke care across hospitals providing SU care. METHODS: Data were derived from the German Stroke Registers Study Group (ADSR), a voluntary network of 9 regional registers for monitoring quality of acute stroke care in Germany. Multivariable logistic regression analyses were performed to investigate characteristics influencing direct admission to SU. Generalized Linear Mixed Models (GLMM) were used to estimate the influence of structural hospital characteristics (percentage of patients admitted to SU, year of SU-certification, and number of stroke and TIA patients treated per year) on adherence to predefined quality indicators. RESULTS: In 2012 180,887 patients were treated in 255 hospitals providing certified SU care participating within the ADSR were included in the analysis; of those 82.4% were directly admitted to a SU. Ischemic stroke patients without disturbances of consciousness (p < .0001), an interval onset to admission time ≤3 h (p < .0001), and weekend admission (p < .0001) were more likely to be directly admitted to a SU. A higher proportion of quality indicators within predefined target ranges were achieved in hospitals with a higher proportion of SU admission (p = 0.0002). Quality of stroke care could be maintained even if certification was several years ago. CONCLUSIONS: Differences in demographical and clinical characteristics regarding the probability of SU admission were observed. The influence of structural characteristics on adherence to evidence-based quality indicators was low.

Is mortality a useful parameter for public reporting in pacemaker implantation? Results of an obligatory external quality control programme.

AIMS: To evaluate if public reporting of pacemaker implantation-associated mortality is meaningful in a large contemporary patient cohort. METHODS AND RESULTS: The database of the obligatory external quality control programme in the Federal State of Hessen, Germany, of patients undergoing permanent pacemaker (PPM) implantation was evaluated retrospectively. We compared the baseline features of patients who died compared with those who did not during hospitalization after PPM. Of 5079 patients who underwent PPM implantation in 2009, 74 (1.5%) died during the hospital stay. Cause of death was available in 70/74 patients (94.6%) who died. Deceased patients were older (79.6 ± 8.7 vs. 76.3 ± 9.9 years, P = 0.006), had worse American Society of Anesthesiologists (ASA) physical status (P < 0.001), lower ejection fraction (P < 0.001), a greater prevalence of high-degree atrioventricular-block (44.3 vs. 35.0%, P = 0.001), and were more likely to receive single-chamber devices (41.4 vs. 25.0%, P < 0.002). Perioperative complications were similar in both cohorts. Death was not attributable directly to PPM procedure in any patients but was related to (i) non-device-related infections (28.6%), (ii) heart failure (25.7%), (iii) extracardiac diseases (21.4%), (iv) multiorgan failure (8.6%), (v) previous resuscitation with hypoxic brain damage (8.6%), and (vi) arrhythmogenic death (7.1%). CONCLUSION: Mortality associated with PPM implantation in vast majority of cases was not related to the procedure, but to comorbidities and other existing diseases at the time of PPM implantation. Thus, PPM implantation in-hospital mortality should not be chosen for public reporting comparing hospital quality, even after adjusting for baseline risk.

Estimating the Quantitative Demand of NOAC Antidote Doses on Stroke Units.

BACKGROUND: The first specific antidote for non-vitamin K antagonist oral anticoagulants (NOAC) has recently been approved. NOAC antidotes will allow specific treatment for 2 hitherto problematic patient groups: patients with oral anticoagulant therapy (OAT)-associated intracerebral hemorrhage (ICH) and maybe also thrombolysis candidates presenting on oral anticoagulation (OAT). We aimed to estimate the frequency of these events and hence the quantitative demand of antidote doses on a stroke unit. METHODS: We extracted data of patients with acute ischemic stroke and ICH (<24 h after symptom onset) in the years 2012-2015 from a state-wide prospective stroke inpatient registry. We selected 8 stroke units and determined the mode of OAT upon admission in 2012-2013. In 2015, the mode of OAT became a mandatory item of the inpatient registry. From the number of anticoagulated patients and the NOAC share, we estimated the current and future demand for NOAC antidote doses on stroke units. RESULTS: Eighteen percent of ICH patients within 6 h of symptom onset or an unknown symptom onset were on OAT. Given a NOAC share at admission of 40%, about 7% of all ICH patients may qualify for NOAC reversal therapy. Thirteen percent of ischemic stroke patients admitted within 4 h presented on anticoagulation. Given the availability of an appropriate antidote, a NOAC share of 50% could lead to a 6.1% increase in thrombolysis rate. CONCLUSIONS: Stroke units serving populations with a comparable demographic structure should prepare to treat up to 1% of all acute ischemic stroke patients and 7% of all acute ICH patients with NOAC antidotes. These numbers may increase with the mounting prevalence of atrial fibrillation and an increasing use of NOAC.

Impact of maternal body mass index on the cesarean delivery rate in Germany from 1990 to 2012.

AIMS: Maternal obesity is a risk factor for cesarean delivery (CD). The aim of this analysis was to determine the association between early-pregnancy body mass index (BMI) and the rate of CD over the past two decades. METHODS: We retrospectively analyzed data from the perinatal quality registry of singleton deliveries in the state of Hesse in Germany from 1990 to 2012. We divided the patients into groups according to the WHO criteria for BMI: underweight (<18.5), normal weight (18.5-<25), overweight (25-<30), obese class I (30-<35), obese class II (35-<40), and obese class III (≥40). RESULTS: The analysis included 1,092,311 patients with available data regarding maternal BMI and mode of delivery. The CD rates for underweight (<18.5), normal weight (18.5-<25), overweight (25-<30), obese class I (30-<35), obese class II (35-<40), and obese class III (≥40) women increased from 14.4%, 16.1%, 19.5%, 22.3%, 25%, and 26.9% in the year 1990 to 27.9%, 31.4%, 38.8%, 45.1%, 50.2%, and 55.2% in the year 2012, respectively (P<0.001). CONCLUSION: Maternal BMI in early pregnancy is linearly associated with the incidence of CD. We found a disproportionate increase of CD in morbidly obese women compared with the CD incidence in the reference BMI population over the past two decades.

Interinstitutional variations in mode of birth after a previous caesarean section: a cross-sectional study in six German hospitals.

AIMS: Regional and interinstitutional variations have been recognized in the increasing incidence of caesarean section. Modes of birth after previous caesarean section vary widely, ranging from elective repeat caesarean section (ERCS) and unplanned repeat caesarean section (URCS) after trial of labour to vaginal birth after caesarean section (VBAC). This study describes interinstitutional variations in mode of birth after previous caesarean section in relation to regional indicators in Germany. MATERIAL AND METHODS: A cross-sectional study using the birth registers of six maternity units (n=12,060) in five different German states (n=370,209). Indicators were tested by χ2 and relative deviations from regional values were expressed as relative risks and 95% confidence intervals. RESULTS: The percentages of women in the six units with previous caesarean section ranged from 11.9% to 15.9% (P=0.002). VBAC was planned for 36.0% to 49.8% (P=0.003) of these women, but actually completed in only 26.2% to 32.8% (P=0.66). Depending on the indicator, the units studied deviated from the regional data by up to 32% [relative risk 0.68 (0.47-0.97)] in respect of completed VBAC among all initiated VBAC. CONCLUSIONS: There is substantial interinstitutional variation in mode of birth following previous caesarean section. This variation is in addition to regional patterns.

Secondary stroke prevention in atrial fibrillation: a challenge in the clinical practice.

BACKGROUND: Despite clear evidence for the effectiveness of oral anticoagulation (OA) in patients with atrial fibrillation (AF), there is evidence for the underutilisation of this therapy in the secondary stroke prevention. We therefore investigate the link between the use of OA in stroke patients with AF and favourable clinical outcome following the acute event. METHODS: The study population was determined by identifying the overlap of two different databases: a stroke registry and claims data of a health insurance company. Baseline data originated from the registry; documented dementia and the prescriptions for OA were derived from the insurance database. Patients with AF, minor physical impairment, and evidence of more than 30 days without further hospitalisation within the subsequent 90 days after the acute event were selected for the analysis. RESULTS: 1828 patients were selected (mean age 77.6 years), 1064 patients (58.2%) were female. 827 patients (45%) received a prescription for OA. The following factors were independently associated with no prescription for oral anticoagulants: increased age (OR: 0.54, CI: 0.46-0.63; P < 0.0001), female sex (OR: 0.77, CI: 0.63-0.94; P < 0.011), worsening disability status at discharge (OR: 0.88, CI: 0.81-0.96; P < 0.006), and documented dementia (OR: 0.54, CI: 0.39-0.73; P < 0.001). Conversely, treatment in a neurological department was associated with prescription for OA (OR: 1.47, CI: 1.19-1.81; P < 0.003). CONCLUSIONS: In more than half of the patients with AF who suffered a stroke OA was not prescribed. The factors associated with reluctance in prescribing anticoagulants are increasing age, female sex, treatment at a non-neurological department, worsening disability, and dementia.

Errors in the classification of pregnant women according to Robson ten-group classification system.

OBJECTIVES: The Robson Ten-Group Classification System (TGCS) is widely used as a classification system for perinatal analyses such as Caesarean section (CS) rates. In Germany, standardised data sets on deliveries are classified by quality assurance institutions using the TGCS. This observational study aims to evaluate potential errors in the TCGS classification of deliveries. STUDY DESIGN: Manual TGCS classification of all 1370 deliveries in an obstetric unit in 2018 and comparison with semi-automatic TGCS classifications of the quality assurance institution. RESULTS: In the manual classification, 259 out of 1370 births (18.9 %) were assigned to a different Robson group than in the semi-automatic classification. The proportions of births by Robson group were significantly different in TGCS group 1 (32.2 % vs. 37.6 %, p = 0.0034) and group 2 (18.4 % vs. 14.4 %, p = 0.0053). Concordance between manual and semi-automatic classifications ranged from 59.5 % in group 2 to 100.0 % in groups 6, 7, 8, and 9. The most frequent mismatches were for the parameters "onset of labour" in 184 cases (13.4 %), "parity" in 42 cases (3.1 %) and "previous uterine scars" in 23 cases (1.7 %). In the manual classification, there were significant differences in the CS rate in group 1 (7.9 % vs. 2.5 %, p < 0.0001), group 2 (30.2 % vs. 48.2 %, p < 0.0001), and group 4 (14.1 % vs. 37.4 %, p = 0.0004), compared to the semi-automatic classification. CONCLUSIONS: Due to incorrect data entry and unclear definitions of criteria, quality assurance data in obstetric databases may contain a relevant proportion of errors, which could influence statistics with TGCS in context of CS rates in international comparisons.

Trends in stroke severity at hospital admission and rehabilitation discharge before and during the COVID-19 pandemic in Hesse, Germany: a register-based study.

BACKGROUND: The COVID-19 pandemic has affected acute stroke care, resulting in a decrease in stroke admissions worldwide. We examined trends in stroke severity at hospital admission, including (1) probable need for rehabilitation (National Institutes of Health Stroke Scale score > 6 points) and (2) probable need for assistance (modified Rankin Scale score > 2 points), and discharge to rehabilitation after acute care among inpatients with acute ischemic stroke and intracerebral hemorrhage. METHODS: We compared quality assurance data for acute ischemic stroke and intracerebral hemorrhage during the pandemic with the period before the pandemic in Hesse, Germany, using logistic regression analyses. RESULTS: Fewer inpatients with a probable need for rehabilitation were present at the beginning of the second wave of the COVID-19 pandemic in September 2020 (adjusted OR (aOR) 0.85, 95% CI [0.73, 0.99]), at the end of the second national lockdown in May 2021 (aOR 0.81, 95% CI [0.70, 0.94]), and at the approaching peak of COVID-19 wave 4 in November 2021 (aOR 0.79, 95% CI [0.68, 091]). Rates of probable need for assistance were significantly lower at the beginning of COVID-19 wave 2 in August 2020 (aOR 0.87, 95% CI [0.77, 0.99]) and at the beginning of COVID-19 wave 3 in March 2021 (aOR 0.80, 95% CI [0.71, 0.91]). Rates of discharge to rehabilitation were lower from the beginning in October 2020 to the peak of COVID-19 wave 2 in December 2020 (aOR 0.83, 95% CI [0.77, 0.90]), at the beginning and end of COVID-19 wave 3 in March 2021 and May 2021 (aOR 0.86, 95% CI [0.79, 0.92]), respectively, and at the beginning of COVID-19 wave 4 in October 2021 (aOR 0.86, 95% CI [0.76, 0.98]). CONCLUSIONS: The results suggest that the COVID-19 pandemic had an impact on stroke management during the pandemic, but the absolute difference in stroke severity at hospital admission and discharge to rehabilitation was small.

Intracerebral hemorrhage in the very old: future demographic trends of an aging population.

BACKGROUND AND PURPOSE: In most European societies and in the United States, the percentage of patients ≥80 years has been rising over the past century. The present study was conducted to observe this demographic change and its impact on patients with intracerebral hemorrhage (ICH). METHODS: We reviewed patients' data with the diagnosis of ICH from January 2007 to December 2009. All data were collected out of a prospective stroke registry covering the entire state of Hesse, Germany. Incidence rates and absolute numbers of patients with ICH for 2009 to 2050 were calculated. RESULTS: Of 3448 patients, 34% had an age ≥80 years. Hospital mortality was 35.9% for patients ≥80 years and 20.0% for patients <80 years. Unfavorable outcome (modified Rankin Scale score >2) was more often found in patients ≥80 years compared with patients <80 years (84.9% versus 74.8%). By the year 2050, the proportion of all patients with ICH ≥80 years will be 2.5-fold higher than in 2009. The total number of ICH cases will increase approximately 35.2% assuming that ICH probability stays the same. The number of patients who die in the hospital will increase approximately 60.2%. The total number of patients with severe disability due to ICH will increase approximately 36.8%. CONCLUSIONS: If current treatment strategies according to age remain unchanged, an increase of in-hospital mortality and a higher proportion of patients who need lifelong care after ICH can be expected in the coming decades.

Reduction of Ischemic Stroke Associated Disability in the Population: A State-Wide Stroke Registry Analysis over a Decade.

(Background): Effective prevention strategies and acute therapies have been established and distributed in recent years to reduce the global burden of stroke. However, beyond randomized clinical trials, limited data exist on the real-world impact of these measures. Our goal was to analyze whether the stroke-associated disability in the population decreased over time based on a state-wide stroke registry analysis. (Methods): Consecutive data from a state-wide inpatient stroke registry covering the entire federal state of Hesse, Germany, were obtained. The clinical data of 141,287 patients with ischemic stroke (ICD-10: I63) admitted between 2010 and 2019 were included. The primary outcome was the odds ratio for a change of modified Ranking Scale (mRS) at discharge over time, estimated by ordinary logistic regression and adjusted for age and sex. The secondary outcome was the odds ratio for a lower National Institutes of Health Stroke Scale (NIHSS) score at hospital admission. (Results): The absolute number of severely disabled (mRS 4−5) stroke patients at discharge decreased over time (2010: 3223 (equivalent to 53/100,000 population); 2019: 2429 [39/100,000 population]). The odds at hospital admission for a higher mRS at discharge decreased significantly by 3.7% per year (OR 0.963 (95% CI 0.960−0.966), p < 0.001). The absolute number of severely affected stroke patients (NIHSS > 15) at admission declined over time (2010: 1589 [26/100,000]; 2019: 1185 [19/100,000]; p < 0.001). The odds for a higher NIHSS score at admission to hospital decreased by 3.8% per year (OR 0.962 (95% CI 0.959−0.965), p < 0.001). Trends were most prominent for patients aged 80 years and older and for patients with atrial fibrillation but absent in patients <60 years. (Conclusions): Stroke-associated disability in the population steadily decreased between 2010 and 2019. The improved prevention of severe strokes in elderly patients may be a major driver of this observation.
