RESUMEN
BACKGROUND: Sepsis is associated with about 20% of deaths worldwide. It often presents with non-specific initial symptoms, making its emergency treatment an interdisciplinary and cross-sectoral challenge. Three in four sepsis survivors suffers from new cognitive, psychological, or physical sequelae for which specific treatment concepts are scarce. The AVENIR project aims to improve the understanding of patient pathways, and subjective care experiences and needs along the entire healthcare pathway before, with and after sepsis. Based on this, concrete recommendations for the organization of care and patient information materials will be developed with close patient participation. METHODS: Mixed-methods study including (1) analysis of anonymized nationwide health claims data from Germany, (2) linkage of health claims data with patient care reports (PCR) of emergency medical services from study regions in two federal states within Germany, and (3) qualitative exploration of the patient, relative, and care provider perspective on sepsis care. In (1), we analyze inpatient and outpatient health care utilization until 30 days pre-sepsis; clinical sepsis care including intra- and inter-hospital transfers; and rehabilitation, inpatient and outpatient aftercare of sepsis survivors as well as costs for health care utilization until 24 months post-sepsis. We attempt to identify survivor classes with similar health care utilization by Latent Class Analyses. In (2), PCR are linked with health claims data to establish a comprehensive database outlining care pathways for sepsis patients from pre-hospital to follow-up. We investigate e.g., whether correct initial assessment is associated with acute (e.g., same-day lethality) and long-term (e.g., new need for care, long-term mortality) outcomes of patients. We compare the performance of sepsis-specific screening tools such as qSOFA, NEWS-2 or PRESEP in the pre-clinical setting. In (3), semi-structured interviews as well as synchronous and asynchronous online focus groups are conducted and analyzed using qualitative content analyses techniques. DISCUSSION: The results of the AVENIR study will contribute to a deeper understanding of sepsis care pathways in Germany. They may serve as a base for improvements and innovations in sepsis care, that in the long-term can contribute to reduce the personal, medical, and societal burden of sepsis and its sepsis sequelae. TRIAL REGISTRATION: Registered at German Clinical Trial Register (ID: DRKS00031302, date of registration: 5th May 2023).

BACKGROUND: Post-traumatic stress has been identified as a frequent long-term complication in survivors of critical illnesses after sepsis. Little is known about long-term trajectories of post-traumatic stress and potentially modifiable risk factors following the ICU stay. Study objective was to explore and compare different clinical trajectories of post-traumatic stress symptoms in sepsis survivors up to two years after discharge from ICU. METHODS: Data on post-traumatic stress symptoms by means of the Post-traumatic Symptom Scale (PTSS-10) were collected in sepsis survivors at one, six, 12 and 24 months after discharge from ICU. Data on chronic psychiatric diagnoses prior ICU were derived from the primary care provider's health records, and data on intensive care treatment from ICU documentation. Trajectories of post-traumatic symptoms were identified ex post, discriminating patterns of change and k-means clustering. Assignment to the trajectories was predicted in multinomial log-linear models. RESULTS: At 24 months, all follow-up measurements of the PTSS-10 were completed in N = 175 patients. Three clusters could be identified regarding clinical trajectories of PTSS levels: stable low symptoms (N = 104 patients [59%]), increasing symptoms (N = 45 patients [26%]), and recovering from symptoms (N = 26 patients [15%]). Patients with initially high post-traumatic symptoms were more likely to show a decrease (OR with 95% CI: 1.1 [1.05, 1.16]). Females (OR = 2.45 [1.11, 5.41]) and patients reporting early traumatic memories of the ICU (OR = 4.04 [1.63, 10]) were at higher risk for increasing PTSS levels. CONCLUSION: Post-traumatic stress is a relevant long-term burden for sepsis patients after ICU stay. Identification of three different trajectories within two years after ICU discharge highlights the importance of long-term observation, as a quarter of patients reports few symptoms at discharge yet an increase in symptoms in the two years following. Regular screening of ICU survivors on post-traumatic stress should be considered even in patients with few symptoms and in particular in females and patients reporting traumatic memories of the ICU.

INTRODUCTION: The delegation of tasks and responsibilities from general practitioners (GPs) to medical practice assistants (MPAs) can contribute to ensuring primary care in Germany. The aim of the study was to collect and analyze attitudes and procedures of GPs and MPAs regarding the delegation of physician-related tasks and activities. METHODOLOGY: A self-designed, piloted questionnaire was sent to all GPs listed within the regional Associations of Statutory Health Insurance Physicians (KV) in Thuringia, Berlin, and Brandenburg (n=5,516) and their MPAs. Participants were asked to indicate which physician-related activities were already delegated and on which occasions further delegations could be considered. RESULTS: 890 GPs (response rate: 16.1%) and 566 MPAs participated in the written survey. The participants were predominantly female and most of them worked in urban areas. Numerous activities, such as medical history taking, triage, Disease Management Program (DMP) controls, vaccinations and home visits, have already been delegated. The willingness to delegate further tasks (e. g., follow-up prescriptions and referrals, independent takeover of simple consultations, assessing the necessity of physician consultation) was high. CONCLUSION: The survey showed a high level of willingness of both occupational groups to delegate physician-related activities to MFAs. An expansion seems possible under certain conditions. Many activities have already been delegated to MPAs in primary care practices. Our survey provides suggestions regarding further tasks suitable for delegation, some of which go beyond the delegation agreement valid in Germany.

INTRODUCTION: Various developments result in increasing workloads in general practices. New models of care and a restructuring of the division of tasks could provide relief. One approach is to extend the delegation of medical tasks from general practitioners (GPs) to medical practice assistants (MPAs). So far, there has been a lack of information about specific situations in which patients are willing to be treated exclusively by MPAs. METHODS: In three German federal states, patients who visited a general practice were surveyed exploratively and cross-sectionally with a self-designed, paper-based questionnaire. The data were analysed descriptively and multivariate. A mixed binary logistic regression model was calculated to account for cluster effects at practice level (random intercept model). The dependent variable was patients' acceptance of task delegation. RESULTS: A total of 1861 questionnaires from 61 general practices were included in the analysis. Regarding the current problem/request, a total of 30% of respondents could imagine being treated only by MPAs. Regarding theoretical reasons for consultation, more than half of the patients agreed to be treated by MPAs. According to the regression model, MPAs were preferred when patients were younger (10-year OR = 0.84, 95%-CI [0.75, 0.93]) or had a less complicated issue (OR = 0.44, 95%-CI [0.26, 0.8]). For four current problems/requests ("acute complaints" OR = 0.27, 95%-CI [0.17, 0.45], "routine health check" OR = 0.48, 95%-CI [0.3, 0.79], "new problem" OR = 0.13, 95%-CI [0.06, 0.28], "known problem" OR = 0.16, 95%-CI [0.1, 0.27]) patients prefer to be treated by GPs instead of MPAs. DISCUSSION: For the first time, statements could be made on patients' acceptance of task delegation in relation to current and theoretical reasons for treatment in general practices in Germany. The discrepancy in response behaviour on a theoretical and individual level could be explained by different contexts of questions and differences at practice level. Overall, patients seem to be open to increased delegation of medical tasks, depending on the reason for treatment. Selection and response biases should be considered in the interpretation. CONCLUSION: The results are not completely opposed to an extension of task delegation. Further interventional studies could provide information on the possible effects of expansion of delegable tasks.

BACKGROUND: ICU survivors often suffer from prolonged physical and mental impairments resulting in the so called "Post-Intensive Care Syndrome" (PICS). The aftercare of former ICU patients affected by PICS in particular has not been addressed sufficiently in Germany so far. The aim of this study was to evaluate the feasibility of a pragmatic randomised trial (RCT) comparing an intensive care unit (ICU) follow-up clinic intervention to usual care. METHODS: This pilot study in a German university hospital evaluated the feasibility of a pragmatic RCT. Patients were assigned in a 1:1 ratio to an ICU follow-up clinic intervention or to usual care. The concept of this follow-up clinic was previously developed in a participatory process with patients, next of kin, health care professionals and researchers. We performed a process evaluation and determined acceptability, fidelity, completeness of measurement instruments and practicality as feasibility outcomes. The RCT's primary outcome (health-related quality of life) was assessed six months after ICU discharge by means of the physical component scale of the Short-Form-12 self-report questionnaire. RESULTS: The pilot study was conducted from June 2020 to May 2021 with 21 and 20 participants in the intervention and control group. Principal findings related to feasibility were 85% consent rate (N = 48), 62% fidelity rate, 34% attrition rate (N = 41) and 77% completeness of outcome measurements. The primary effectiveness outcome (health-related quality of life) could be measured in 93% of participants who completed the study (N = 27). The majority of participants (85%) needed assistance with follow-up questionnaires (practicality). Median length of ICU stay was 13 days and 85% (N = 41) received mechanical ventilation, median Sequential Organ Failure Assessment Score was nine. Six-month follow-up assessment was planned for all study participants and performed for 66% (N = 41) of the participants after 197 days (median). CONCLUSION: The participatory developed intervention of an ICU follow-up clinic and the pragmatic pilot RCT both seem to be feasible. We recommend to start a pragmatic RCT on the effectiveness of the ICU follow-up clinic.

The rate of the final step in the astrophysical αp process, the ^{34}Ar(α,p)^{37}K reaction, suffers from large uncertainties due to a lack of experimental data, despite having a considerable impact on the observable light curves of x-ray bursts and the composition of the ashes of hydrogen and helium burning on accreting neutron stars. We present the first direct measurement constraining the ^{34}Ar(α,p)^{37}K reaction cross section, using the Jet Experiments in Nuclear Structure and Astrophysics gas jet target. The combined cross section for the ^{34}Ar,Cl(α,p)^{37}K,Ar reaction is found to agree well with Hauser-Feshbach predictions. The ^{34}Ar(α,2p)^{36}Ar cross section, which can be exclusively attributed to the ^{34}Ar beam component, also agrees to within the typical uncertainties quoted for statistical models. This indicates the applicability of the statistical model for predicting astrophysical (α,p) reaction rates in this part of the αp process, in contrast to earlier findings from indirect reaction studies indicating orders-of-magnitude discrepancies. This removes a significant uncertainty in models of hydrogen and helium burning on accreting neutron stars.

BACKGROUND: The results of critical illness and life-saving invasive measures during intensive care unit treatment can sometimes lead to lasting physical and psychological impairments. A multicentre randomized controlled trial from Germany (PICTURE) aims to test a brief psychological intervention, based on narrative exposure therapy, for post-traumatic stress disorder symptoms following intensive care unit treatment in the primary care setting. A qualitative analysis was conducted to understand feasibility and acceptance of the intervention beyond quantitative analysis of the main outcomes in the primary study. METHODS: Qualitative explorative sub-study of the main PICTURE trial, with eight patients from the intervention group recruited for semi-structured telephone interviews. Transcriptions were analysed according to Mayring's qualitative content analysis. Contents were coded and classified into emerging categories. RESULTS: The study population was 50% female and male, with a mean age of 60.9 years and transplantation surgery being the most frequent admission diagnosis. Four main factors were identified as conducive towards implementation of a short psychological intervention in a primary care setting: 1) long-term trustful relationship between patient and GP team; 2) intervention applied by a medical doctor; 3) professional emotional distance of the GP team; 4) brevity of the intervention. CONCLUSION: The primary setting has certain qualities such as a long-term doctor-patient relationship and low-threshold consultations that offer good opportunities for implementation of a brief psychological intervention for post-intensive care unit impairments. Structured follow-up guidelines for primary care following intensive care unit treatment are needed. Brief general practice-based interventions could be part of a stepped-care approach. TRIAL REGISTRATION: The main trial was registered at the DRKS (German Register of Clinical Trials: DRKS00012589) on 17/10/2017.

BACKGROUND: Due to the increasing use of online health information, symptom checkers have been developed to provide an individualized assessment of health complaints and provide potential diagnoses and an urgency estimation. It is assumed that they support patient empowerment and have a positive impact on patient-physician interaction and satisfaction with care. Particularly in the emergency department (ED), symptom checkers could be integrated to bridge waiting times in the ED, and patients as well as physicians could take advantage of potential positive effects. Our study therefore aims to assess the impact of symptom assessment application (SAA) usage compared to no SAA usage on the patient-physician interaction in self-referred walk-in patients in the ED population. METHODS: In this multi-center, 1:1 randomized, controlled, parallel-group superiority trial, 440 self-referred adult walk-in patients with a non-urgent triage category will be recruited in three EDs in Berlin. Eligible participants in the intervention group will use a SAA directly after initial triage. The control group receives standard care without using a SAA. The primary endpoint is patients' satisfaction with the patient-physician interaction assessed by the Patient Satisfaction Questionnaire. DISCUSSION: The results of this trial could influence the implementation of SAA into acute care to improve the satisfaction with the patient-physician interaction.

BACKGROUND: Symptom checkers are digital tools assisting laypersons in self-assessing the urgency and potential causes of their medical complaints. They are widely used but face concerns from both patients and health care professionals, especially regarding their accuracy. A 2015 landmark study substantiated these concerns using case vignettes to demonstrate that symptom checkers commonly err in their triage assessment. OBJECTIVE: This study aims to revisit the landmark index study to investigate whether and how symptom checkers' capabilities have evolved since 2015 and how they currently compare with laypersons' stand-alone triage appraisal. METHODS: In early 2020, we searched for smartphone and web-based applications providing triage advice. We evaluated these apps on the same 45 case vignettes as the index study. Using descriptive statistics, we compared our findings with those of the index study and with publicly available data on laypersons' triage capability. RESULTS: We retrieved 22 symptom checkers providing triage advice. The median triage accuracy in 2020 (55.8%, IQR 15.1%) was close to that in 2015 (59.1%, IQR 15.5%). The apps in 2020 were less risk averse (odds 1.11:1, the ratio of overtriage errors to undertriage errors) than those in 2015 (odds 2.82:1), missing >40% of emergencies. Few apps outperformed laypersons in either deciding whether emergency care was required or whether self-care was sufficient. No apps outperformed the laypersons on both decisions. CONCLUSIONS: Triage performance of symptom checkers has, on average, not improved over the course of 5 years. It decreased in 2 use cases (advice on when emergency care is required and when no health care is needed for the moment). However, triage capability varies widely within the sample of symptom checkers. Whether it is beneficial to seek advice from symptom checkers depends on the app chosen and on the specific question to be answered. Future research should develop resources (eg, case vignette repositories) to audit the capabilities of symptom checkers continuously and independently and provide guidance on when and to whom they should be recommended.

Hundreds of thousands of individuals who experience lasting sequelae after sepsis and infections in Germany do not receive optimal care. In this White Paper we present measures for improvement, which were developed by a multidisciplinary expect panel as part of the SEPFROK project. Improved care rests on four pillars: 1. cross-sectoral assessment of sequelae and a structured discharge and transition management, 2. interdisciplinary rehabilitation and aftercare with structural support, 3. strengthening the specific health literacy of patients and families, and 4. increased research into causes, prevention and treatment of sequelae. To achieve this, appropriate cross-sectoral care structures and legal frameworks must be created.

Background: Survivors of sepsis often face long-term sequelae after intensive care treatment. Compared to the period of hospitalization, little is known about the ambulatory healthcare utilization in sepsis patients. The study evaluated healthcare utilization and associated costs of sepsis care including allied health professions after initial hospitalization. Methods: Secondary analysis was performed on data in 210 sepsis patients prospectively enrolled from nine intensive care study centers across Germany. Data was collected via structured surveys among their Primary care (Family-) physicians (PCPs) within the first month after discharge from ICU (baseline) and again at 6, 12 and 24 months after discharge, each relating to the period following the last survey. Costs were assessed by standardized cost unit rates from a health care system's perspective. Changes in healthcare utilization and costs over time were calculated using the Wilcoxon rank-sum test. Results: Of the 210 patients enrolled, 146 (69.5%) patients completed the 24 months follow-up. In total, 109 patients were hospitalized within the first 6 months post-intensive care. Mean total direct costs per patient at 0-6 months were 17,531 (median: 6047), at 7-12 months 9029 (median: 3312), and at 13-24 months 18,703 (median: 12,828). The largest contributor to the total direct costs within the first 6 months was re-hospitalizations (13,787 (median: 2965). After this first half year, we observed a significant decline in inpatient care costs for re-hospitalizations (p ≤ 0.001). PCPs were visited by more than 95% of patients over 24 months. Conclusions: Sepsis survivors have high health care utilization. Hospital readmissions are frequent and costly. Highest costs and hospitalizations were observed in more than half of patients within the first six months post-intensive care. Among all outpatient care providers, PCPs were consulted most frequently. Clinical impact: Sepsis survivors have a high healthcare utilization and related costs which persist after discharge from hospital. Within outpatient care, possible needs of sepsis survivors as physiotherapy or psychotherapy seem not to be met appropriately. Development of sepsis aftercare programs for early detection and treatment of complications should be prioritized.
RESUMEN
As of July 31, 2021, SARS-CoV-2 had infected almost 200 million people worldwide. The growing burden of survivorship is substantial in terms of the complexity of long-term health effects and the number of people affected. Persistent symptoms have been reported in patients with both mild and severe acute COVID-19, including those admitted to the intensive care unit (ICU). Early reports on the post-acute sequelae of SARS-CoV-2 infection (PASC) indicate that fatigue, dyspnoea, cough, headache, loss of taste or smell, and cognitive or mental health impairments are among the most common symptoms. These complex, multifactorial impairments across the domains of physical, cognitive, and mental health require a coordinated, multidisciplinary approach to management. Decades of research on the multifaceted needs of and models of care for patients with post-intensive care syndrome provide a framework for the development of PASC clinics to address the immediate needs of both hospitalised and non-hospitalised survivors of COVID-19. Such clinics could also provide a platform for rigorous research into the natural history of PASC and the potential benefits of therapeutic interventions.

BACKGROUND: Advances in critical care medicine have led to a growing number of critical illness survivors. A considerable part of them suffers from long-term sequelae, also known as post-intensive care syndrome. Among these, depressive symptoms are frequently observed. Depressive symptom trajectories and associated factors of critical illness survivors have rarely been investigated. Study objective was to explore and compare different trajectories of depressive symptoms in sepsis survivors over 1 year after discharge from ICU. METHODS: Data of a randomized controlled trial on long-term post-sepsis care were analyzed post hoc. Depressive symptoms were collected at 1, 6 and 12 months post-ICU discharge using the Major Depression Inventory (MDI), among others. Statistical analyses comprised descriptive analysis, univariate and multivariate, linear and logistic regression models and Growth Mixture Modeling. RESULTS: A total of 224 patients were included into this analysis. We identified three latent classes of depressive symptom trajectories: Over the course of 1 year, 152 patients recovered from mild symptoms, 27 patients showed severe persistent symptoms, and 45 patients recovered from severe symptoms. MDI sum scores significantly differed between the three classes of depressive symptom trajectories at 1 and 6 months after ICU discharge (p < 0.024 and p < 0.001, respectively). Compared with other classes, patients with the mild recovered trajectory showed lower levels of chronic pain (median sum score of 43.3 vs. 60.0/53.3 on the Graded Chronic Pain Scale, p < 0.010) and posttraumatic stress (4.6% with a sum score of ≥ 35 on the Posttraumatic Stress Scale 10 vs. 48.1%/33.3%, p < 0.003); and higher levels of health-related quality of life (HRQOL) using the Short Form-36 scale within 1 month after ICU discharge (p < 0.035). CONCLUSIONS: In the first year after discharge from ICU, sepsis survivors showed three different trajectories of depressive symptoms. Course and severity of depressive symptoms were associated with chronic pain, posttraumatic stress and reduced HRQOL at discharge from ICU. Regular screening of sepsis survivors on symptoms of depression, chronic pain and posttraumatic stress within 1 year after ICU may be considered. Trial registration ISRCTN, ISRCTN 61744782.

BACKGROUND: Patients surviving critical illnesses, such as sepsis, often suffer from long-term complications. After discharge from hospital, most patients are treated in primary care. Little is known how general practitioners (GPs) perform critical illness aftercare and how it can be improved. Within a randomised controlled trial, an outreach training programme has been developed and applied. OBJECTIVES: The aim of this study is to describe GPs' views and experiences of caring for postsepsis patients and of participating a specific outreach training. DESIGN: Semistructured qualitative interviews. SETTING: 14 primary care practices in the metropolitan area of Berlin, Germany. PARTICIPANTS: 14 GPs who had participated in a structured sepsis aftercare programme in primary care. RESULTS: Themes identified in sepsis aftercare were: continuity of care and good relationship with patients, GP's experiences during their patient's critical illness and impact of persisting symptoms. An outreach education as part of the intervention was considered by the GPs to be acceptable, helpful to improve knowledge of the management of postintensive care complications and useful for sepsis aftercare in daily practice. CONCLUSIONS: GPs provide continuity of care to patients surviving sepsis. Better communication at the intensive care unit-GP interface and training in management of long-term complications of sepsis may be helpful to improve sepsis aftercare.

In recent years 3D-bioprinting technology has been developed as an alternative to animal testing. It possesses a great potential for in vitro testing as it aims to mimic human organs and physiology. In the present study, an alginate-gelatin-Matrigel based hydrogel was used to prepare 3D-bioprinted HepaRG cultures using a pneumatic extrusion printer. These 3D models were tested for viability and metabolic functions. Using 3D-bioprinted HepaRG cultures, we tested the toxicity of aflatoxin B1 (10 or 20 µM) in vitro and compared the results with 2D HepaRG cultures. There was a dose-dependent toxicity effect on cell viability, reduction of metabolic activity and albumin production. We found that 3D-bioprinted HepaRG cultures are more resistant to aflatoxin B1 treatment than 2D cultures. Although the metabolic activities were reduced upon treatment with aflatoxin B1, the 3D models were still viable and survived longer, up to 3 weeks, than the 2D culture, as visualized by fluorescence microscopy. Furthermore, albumin production recovered slightly in 3D models after one and two weeks of treatment. Taken together, we consider using 3D-bioprinting technology to generate 3D tissue models as an alternative way to study toxicity in vitro and this could also provide a suitable alternative for chronic hepatotoxicity studies in vitro.
RESUMEN
BACKGROUND: Patients who survive critical illness suffer from a significant physical disability. The impact of rehabilitation strategies on health-related quality of life is inconsistent, with population heterogeneity cited as one potential confounder. This secondary analysis aimed to (1) examine trajectories of functional recovery in critically ill patients to delineate sub-phenotypes and (2) to assess differences between these cohorts in both clinical characteristics and clinimetric properties of physical function assessment tools. METHODS: Two hundred ninety-one adult sepsis survivors were followed-up for 24 months by telephone interviews. Physical function was assessed using the Physical Component Score (PCS) of the Short Form-36 Questionnaire (SF-36) and Activities of Daily Living and the Extra Short Musculoskeletal Function Assessment (XSFMA-F/B). Longitudinal trajectories were clustered by factor analysis. Logistical regression analyses were applied to patient characteristics potentially determining cluster allocation. Responsiveness, floor and ceiling effects and concurrent validity were assessed within clusters. RESULTS: One hundred fifty-nine patients completed 24 months of follow-up, presenting overall low PCS scores. Two distinct sub-cohorts were identified, exhibiting complete recovery or persistent impairment. A third sub-cohort could not be classified into either trajectory. Age, education level and number of co-morbidities were independent determinants of poor recovery (AUROC 0.743 ((95%CI 0.659-0.826), p < 0.001). Those with complete recovery trajectories demonstrated high levels of ceiling effects in physical function (PF) (15%), role physical (RP) (45%) and body pain (BP) (57%) domains of the SF-36. Those with persistent impairment demonstrated high levels of floor effects in the same domains: PF (21%), RP (71%) and BP (12%). The PF domain demonstrated high responsiveness between ICU discharge and at 6 months and was predictive of a persistent impairment trajectory (AUROC 0.859 (95%CI 0.804-0.914), p < 0.001). CONCLUSIONS: Within sepsis survivors, two distinct recovery trajectories of physical recovery were demonstrated. Older patients with more co-morbidities and lower educational achievements were more likely to have a persistent physical impairment trajectory. In regard to trajectory prediction, the PF score of the SF-36 was more responsive than the PCS and could be considered for primary outcomes. Future trials should consider adaptive trial designs that can deal with non-responders or sub-cohort specific outcome measures more effectively.

BACKGROUND: Evidence-based psychological interventions for posttraumatic stress disorder (PTSD) are available in specialized settings, but adequate care in primary care is often lacking. The aim of this systematic review was to determine the effectiveness of psychological interventions for PTSD involving primary care physicians (PCPs) and to characterize these interventions as well as their providers. METHOD: A systematic review and meta-analyses of randomized controlled trials (RCTs). Primary outcome were symptoms of PTSD. RESULTS: Four RCTs with a total of 774 patients suffering from PTSD symptoms were included, all applying cognitive behavioural based interventions. Three studies with psychological interventions being conducted by case managers were pooled in a meta-analysis. Interventions were not effective in the short term (0-6 months; SMD, - 0.1; 95% CI, - 0.24-0.04; I2 = 0%). Only two studies contributed to the meta-analysis for long term (12-18 months) outcomes yielding a small effect (SMD, - 0.23; 95% CI, - 0.38- -0.08; I2 = 0%). CONCLUSIONS: Psychological interventions for PTSD in primary care settings may be effective in the long term but number and quality of included studies was limited so the results should be interpreted with caution.

BACKGROUND: Sepsis survivors face mental and physical sequelae even years after discharge from the intensive care unit. The aim of this study was to evaluate the long-term courses of sepsis survivors and the effects of a primary care management intervention in sepsis aftercare. METHODS: This study presents a 24-month follow-up of a randomized controlled trial that recruited 291 patients who survived sepsis (including septic shock) from nine German intensive care units. Participants were randomized to usual care (n=143) or to a 12-month-intervention (n=148). The intervention included training of patients and their primary care physicians (PCP) in evidence-based post-sepsis care, case management provided by trained nurses, and clinical decision support for PCPs by consulting physicians. Usual care was provided by PCPs in the control group. At the 24-month follow-up, 12 months after the 1-year-intervention, survival and measures of mental and physical health were collected by telephone interviews. RESULTS: One hundred eighty-six (63.9%, 98 intervention, 88 control) of 291 patients completed the 24-month follow-up, showing both increased mortality and recovery from functional impairment. Unlike the intervention group, the control group showed a significant increase of posttraumatic stress symptoms according to the Posttraumatic Symptom Scale (difference between baseline and 24-months follow-up values, mean [standard deviation] 3.7 [11.8] control vs -0.7 [12.1] intervention; Pâ¯=â¯.016). There were no significant differences in all other outcomes between the intervention and control groups. CONCLUSIONS: Twelve months after completion, a primary care management intervention among survivors of sepsis did not improve mental health-related quality of life. Patients in the intervention group showed less posttraumatic stress symptoms.

BACKGROUND: There have not yet been any prospective registry studies in Germany with active investigation of the long-term survival of patients with sepsis. METHODS: The Jena Sepsis Registry (JSR) included all patients with a diagnosis of sepsis in the four intensive care units of Jena University Hospital from January 2011 to December 2015. Long-term survival 6-48 months after diagnosis was documented by asking the treating general practitioners. The survival times were studied with Kaplan-Meier estimators. Cox regressions were calculated to show associations between possible predictors and survival time. RESULTS: 1975 patients with sepsis or septic shock were included. The mean time of observation was 730 days. For 96.4% of the queries to the general practitioners, information on long-term survival was available. Mortality in the intensive care unit was 34% (95% confidence interval [32; 37]), and in-hospital mortality was 45% [42; 47]. The overall mortality six months after diagnosis was 59% [57; 62], the overall mortality 48 months after diagnosis was 74% [72; 78]. Predictors of shorter survival were age, nosocomial origin of sepsis, diabetes, cerebrovascular disease, duration of stay in the intensive care unit, and renal replacement therapy. CONCLUSION: The nearly 75% mortality four years after diagnosis indicates that changes are needed both in the acute treatment of patients with sepsis and in their multi-sector long-term care. The applicability of these findings may be limited by their having been obtained in a single center.

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