Interprofessional collaboration and patient-reported outcomes: a secondary data analysis based on large scale survey data.

BACKGROUND: While interprofessional collaboration (IPC) is widely considered a key element of comprehensive patient treatment, evidence focusing on its impact on patient-reported outcomes (PROs) is inconclusive. The aim of this study was to investigate the association between employee-rated IPC and PROs in a clinical inpatient setting. METHODS: We conducted a secondary data analysis of the entire patient and employee reported data collected by the Picker Institute Germany in cross-sectional surveys between 2003 and 2016. Individual patient data from departments within hospitals was matched with employee survey data from within 2 years of treatment at the department-level. Items assessing employee-rated IPC (independent variables) were included in Principal Component Analysis (PCA). All questions assessing PROs (overall satisfaction, less discomforts, complications, treatment success, willingness to recommend) served as main dependent variables in ordered logistic regression analyses. Results were adjusted for multiple hypothesis testing as well as patients' and employees' gender, age, and education. RESULTS: The data set resulted in 6154 patients from 19 hospitals respective 103 unique departments. The PCA revealed three principal components (department-specific IPC, interprofessional organization, and overall IPC), explaining 67% of the total variance. The KMO measure of sampling adequacy was .830 and Bartlett's test of sphericity highly significant (p < 0.001). An increase of 1 SD in department-specific IPC was associated with a statistically significant chance of a higher (i.e., better) PRO-rating about complications after discharge (OR 1.07, 95% CI 1.00-1.13, p = 0.029). However, no further associations were found. Exploratory analyses revealed positive coefficients of department-specific IPC on all PROs for patients which were treated in surgical or internal medicine departments, whereas results were ambiguous for pediatric patients. CONCLUSIONS: The association between department-level IPC and patient-level PROs remains - as documented in previous literature - unclear and results are of marginal effect sizes. Future studies should keep in mind the different types of IPC, their specific characteristics and possible effect mechanisms.

A systematic review and time-response meta-analysis of the optimal timing of elective caesarean sections for best maternal and neonatal health outcomes.

BACKGROUND: The rate of caesarean sections (CS) has increased in the last decades to about 30% of births in high income countries. Many CSs are electively planned without an urgent medical reason for mother or child. An early CS though may harm the newborn. Our aim was to evaluate the gestational time point after the 37 + 0 week of gestation (WG) (after prematurity = term) of performing an elective CS with the lowest morbidity for mother and child by assessing the time course from 37 + 0 to 42+ 6 WG. METHODS: We performed a systematic literature search in MEDLINE, EMBASE, CENTRAL and CINAHL in November 2018. We included studies that compared different time points of elective CS at term no matter the reason for elective CS. Our primary outcomes were the rate of admissions to the neonatal intensive care unit (NICU), neonatal death and maternal death in early versus late term elective CS. Various binary and dose response random effects meta-analyses were performed. RESULTS: We identified 35 studies including 982,749 women. Except one randomised controlled trial, all studies were cohort studies. We performed a linear time-response meta-analysis on the primary outcome NICU admission on 14 studies resulting in a decrease of the relative risk (RR) to 0.63 (95% CI 0.56, 0.71) from 37 + 0 to 39 + 6 WG. RR for neonatal death showed a decrease to 39 + (0-6) WG (RR 0.59 95% CI 0.43 to 0.83) and increase from then on (RR 2.09 95% CI 1.18 to 3.70) assuming a U-shape course and using a cubic spline model for meta-analysis of four studies. We only identified one study analyzing maternal death resulting in RR of 0.38 (95% CI 0.04 to 3.40) for 37 + 0 + 38 + 6 WG versus ≥39 + 0 WG. CONCLUSION: Our systematic review showed that elective CS (primary and repeated) before the 39 + 0 WG lead to more NICU admissions and neonatal deaths, although death is rare and increases again after 39 + 6 WG. We did not find enough evidence on maternal outcomes. There is a need for more research, considering maternal outcomes to provide a balanced decision between neonatal and maternal health.

["If they were to stop coming, I'd panic" : Palliative care networks from the perspectives of patients and informal care givers]. / "Wenn die mal nicht mehr kommen würden, dann kriege ich eine Krise" : Netzwerke der ambulanten Palliativversorgung aus Sicht von Patienten und Angehörigen.

OBJECTIVE: This study examines the perspectives of patients and family caregivers on outpatient palliative care networks. It contrasts primary palliative care (AAPV) and specialized outpatient care (SAPV) services, particularly in regard to pain management. METHODS: The study is based on 27 semi-structured, problem-focussed interviews with 21 patients and 19 informal caregivers. Recruitment was based on purposive sampling in two regions of Brandenburg, Germany. The data were analysed using qualitative content analysis. RESULTS: In AAPV, the general practitioner (GP) is both the central point of contact as well as the coordinator of the care network. In SAPV, the GP plays a less important role. This can lead to conflicts between GPs and health care professionals of the palliative care team. Compared to AAPV, palliative care teams are attributed greater intervention capacities in acute situations as well as expertise in pain therapy. Thus, the option of parenteral administration of opioids is considered a benefit of specialized care. The use of nursing services varies considerably depending on the individual care network-in some cases care is completely taken over by relatives. Relatives are the closest to the patient within the care network and perform key tasks. CONCLUSION: The personal and professional composition of networks of outpatient palliative care varies individually according to care situation and form. Care networks of AAPV and SAPV differ with regard to the accessibility of health care professionals and pain therapy. Home-based palliative care is often made possible by informal care givers in the first place.

External Validation and Update of the RICP-A Multivariate Model to Predict Chronic Postoperative Pain.

Objective: The development of chronic postsurgical pain (CPSP) is influenced by several factors. The risk index for chronic pain (RICP) was developed to identify patients at high risk for CPSP. The aim of this study was the external validation and update of the RICP. Design: Prospective cohort study. Setting: Two German hospitals. Subjects: Participants who underwent orthopedic surgery, general surgery, visceral surgery, and neurosurgery. Methods: The predicted outcome was CPSP at six months. We validated the original RICP externally and performed a model update. Analysis was performed using logistic regression. We analyzed the discrimination and calibration of the model. Furthermore, the updated model was internally validated. Results: We included 205 patients. The mean age of participants was 51 years. CPSP was reported by 53.9% of participants. In our population, the original RICP (preoperative pain in the operating field, other preoperative pain, postoperative acute pain, capacity overload, and comorbid stress symptoms) showed a sensitivity of 0.708 and a specificity of 0.727 (area under the curve [AUC] = 0.766, 95% confidence interval [CI] = 0.688-0.843). The updated RICP (preoperative pain in the operating field, other preoperative pain, postoperative acute pain, sex, marital status) yielded a sensitivity of 0.746 and a specificity of 0.726 (AUC = 0.813, 95% CI = 0.740-0.886). The results were confirmed by cross-validation. Pre- and postoperative pain measures showed the highest predictive ability. Discussion: The study indicates external validity of the original RICP. The updated RICP also showed good predictive ability. The results are limited by the small sample size and the amount of missing outcome data.

Guideline appraisal with AGREE II: online survey of the potential influence of AGREE II items on overall assessment of guideline quality and recommendation for use.

BACKGROUND: The AGREE II instrument is the most commonly used guideline appraisal tool. It includes 23 appraisal criteria (items) organized within six domains. AGREE II also includes two overall assessments (overall guideline quality, recommendation for use). Our aim was to investigate how strongly the 23 AGREE II items influence the two overall assessments. METHODS: An online survey of authors of publications on guideline appraisals with AGREE II and guideline users from a German scientific network was conducted between 10th February 2015 and 30th March 2015. Participants were asked to rate the influence of the AGREE II items on a Likert scale (0 = no influence to 5 = very strong influence). The frequencies of responses and their dispersion were presented descriptively. RESULTS: Fifty-eight of the 376 persons contacted (15.4%) participated in the survey and the data of the 51 respondents with prior knowledge of AGREE II were analysed. Items 7-12 of Domain 3 (rigour of development) and both items of Domain 6 (editorial independence) had the strongest influence on the two overall assessments. In addition, Items 15-17 (clarity of presentation) had a strong influence on the recommendation for use. Great variations were shown for the other items. The main limitation of the survey is the low response rate. CONCLUSIONS: In guideline appraisals using AGREE II, items representing rigour of guideline development and editorial independence seem to have the strongest influence on the two overall assessments. In order to ensure a transparent approach to reaching the overall assessments, we suggest the inclusion of a recommendation in the AGREE II user manual on how to consider item and domain scores. For instance, the manual could include an a-priori weighting of those items and domains that should have the strongest influence on the two overall assessments. The relevance of these assessments within AGREE II could thereby be further specified.

SYSTEMATIC REVIEWS OF ECONOMIC EVALUATIONS IN HEALTH TECHNOLOGY ASSESSMENT: A REVIEW OF CHARACTERISTICS AND APPLIED METHODS.

OBJECTIVES: When making decisions in health care, it is essential to consider economic evidence about an intervention. The objective of this study was to analyze the methods applied for systematic reviews of health economic evaluations (SR-HEs) in HTA and to identify common challenges. METHODS: We manually searched the Web pages of HTA organizations and included HTA-reports published since 2015. Prerequisites for inclusion were the conduct of an SR-HE in at least one electronic database and the use of the English, German, French, or Spanish language. Methodological features were extracted in standardized tables. We prepared descriptive statistical (e.g., median, range) measures to describe the applied methods. Data were synthesized in a structured narrative way. RESULTS: Eighty-three reports were included in the analysis. We identified inexplicable heterogeneity, particularly concerning literature search strategy, data extraction, assessment of quality, and applicability. Furthermore, process steps were often missing or reported in a nontransparent way. The use of a standardized data extraction form was indicated in one-third of reports (32 percent). Fifty-four percent of authors systematically appraised included studies. In 10 percent of reports, the applicability of included studies was assessed. Involvement of two reviewers was rarely reported for the study selection (43 percent), data extraction (28 percent), and quality assessment (39 percent). CONCLUSIONS: The methods applied for SR-HEs in HTA and their reporting quality are very heterogeneous. Efforts toward a detailed, standardized guidance for the preparation of SR-HEs definitely seem necessary. A general harmonization and improvement of the applied methodology would increase the value of SR-HE for decision makers.

[Patients are Satisfied with the Physician-Patient Communication: A Pilot Study Applying the "Individual Clinician Feedback" Questionnaire]. / Patienten zeigen sich zufrieden mit der Arzt-Patienten-Kommunikation ­ eine Pilotstudie mit dem "Individual Clinician Feedback"- Fragebogen.

AIM OF THE STUDY: Patient-centeredness as an essential aspect of quality of patient care is becoming increasingly important. The aim of the pilot study is to gain insight into the physician-patient communication from the patient's perspective. A German questionnaire in a maximum care hospital was tested. METHODS: The German "Individual Clinician Feedback" questionnaire (ICF) was tested in a pilot study in the special consultation in a voluntary cohort of surgeons. In the survey period from June to August 2015, the questionnaire was given to the patient. The physicians received their assessment results as a compressed score. They were rated on a scale of 1-10 on which 10 is "very good". RESULTS: 12 physicians were recruited from five departments. There was a high response rate of 46% (n=219). The patients evaluated the communication as very good (on average over all items and physicians 8.5 to 9.5 points). 89% of the patients had the feeling that the doctor took adequate time for them, while 50% of the patients had a consultation time of 11-20 min. 12% of the patients had still open questions after treatment that they did not ask. 19% and 21% of patients reported that the physician has not asked them if they had any questions, or that they just forgot about it at the end of treatment. CONCLUSION: The results of the pilot study are associated with a good response rate and patients were mostly very satisfied with the physician-patient communication. However, a selection bias among participating physicians is likely.

The European guideline on management of major bleeding and coagulopathy following trauma: fourth edition.

BACKGROUND: Severe trauma continues to represent a global public health issue and mortality and morbidity in trauma patients remains substantial. A number of initiatives have aimed to provide guidance on the management of trauma patients. This document focuses on the management of major bleeding and coagulopathy following trauma and encourages adaptation of the guiding principles to each local situation and implementation within each institution. METHODS: The pan-European, multidisciplinary Task Force for Advanced Bleeding Care in Trauma was founded in 2004 and included representatives of six relevant European professional societies. The group used a structured, evidence-based consensus approach to address scientific queries that served as the basis for each recommendation and supporting rationale. Expert opinion and current clinical practice were also considered, particularly in areas in which randomised clinical trials have not or cannot be performed. Existing recommendations were reconsidered and revised based on new scientific evidence and observed shifts in clinical practice; new recommendations were formulated to reflect current clinical concerns and areas in which new research data have been generated. This guideline represents the fourth edition of a document first published in 2007 and updated in 2010 and 2013. RESULTS: The guideline now recommends that patients be transferred directly to an appropriate trauma treatment centre and encourages use of a restricted volume replacement strategy during initial resuscitation. Best-practice use of blood products during further resuscitation continues to evolve and should be guided by a goal-directed strategy. The identification and management of patients pre-treated with anticoagulant agents continues to pose a real challenge, despite accumulating experience and awareness. The present guideline should be viewed as an educational aid to improve and standardise the care of the bleeding trauma patients across Europe and beyond. This document may also serve as a basis for local implementation. Furthermore, local quality and safety management systems need to be established to specifically assess key measures of bleeding control and outcome. CONCLUSIONS: A multidisciplinary approach and adherence to evidence-based guidance are key to improving patient outcomes. The implementation of locally adapted treatment algorithms should strive to achieve measureable improvements in patient outcome.

Laparoscopic versus open appendectomy in patients with suspected appendicitis: a systematic review of meta-analyses of randomised controlled trials.

BACKGROUND: Several systematic reviews (SRs) of randomised controlled trials (RCTs) comparing laparoscopic versus open appendectomy have been published, but there has been no overview of SRs of these two interventions. This overview (review of review) aims to summarise the results of such SRs in order to provide the most up to date evidence, and to highlight discordant results. METHODS: Medline, Embase, Cinahl, the Cochrane Database of Systematic Reviews and the Database of Abstracts of Reviews of Effects were searched for SRs published up to August 2014. Study selection and quality assessment using the AMSTAR tool were carried out independently by two reviewers. We used standardised forms to extract data that were analysed descriptively. RESULTS: Nine SRs met the inclusion criteria. All were of moderate to high quality. The number of randomized controlled trials (RCTs) they included ranged from eight to 67. The duration of surgery pooled by eight reviews was 7.6 to 18.3 minutes shorter using the open approach. Pain scores on the first postoperative day were lower after laparoscopic appendectomy in two out of three reviews. The risk of abdominal abscesses was higher for laparoscopic surgery in half of six meta-analyses. The occurrence of wound infections pooled by all reviews was lower after laparoscopic appendectomy. One review showed no difference in mortality. The laparoscopic approach shortened hospital stay from 0.16 to 1.13 days in seven out of eight meta-analyses, though the strength of the evidence was affected by strong heterogeneity. CONCLUSION: Laparoscopic and open appendectomy are both safe and effective procedures for the treatment of acute appendicitis. This overview shows discordant results with respect to the magnitude of the effect but not to the direction of the effect. The evidence from this overview may prove useful for the development of clinical guidelines and protocols.

[Genius between music and disease: Medical considerations on Ludwig van Beethoven]. / Genie zwischen Kunst und Krankheit: Medizinische Betrachtungen zu Ludwig van Beethoven.

Ludwig van Beethoven is nowadays considered to be one of the greatest composers in the history of music and his myth-like reputation is enhanced by his deafness; however, deafness was not the only condition which affected his genius. Due to the many lamentations contained in his letters about continuously recurring health problems, various attempts at an interpretation of Beethoven's personality have been undertaken. These included psychoanalytical considerations with respect to his father-mother relationship and also diagnostic attempts with reference to the symptoms of a possible borderline personality syndrome. The aim of this article is to comprehensively analyze the diseases of the patient Beethoven from the perspective of specialized medical disciplines based on new research results, to summarize various discipline-specific considerations and to make a contemporary assessment from the viewpoint of current scientific results.

Adipose-derived stem cells and keratinocytes in a chronic wound cell culture model: the role of hydroxyectoine.

Chronic wounds represent a major socio-economic problem in developed countries today. Wound healing is a complex biological process. It requires a well-orchestrated interaction of mediators, resident cells and infiltrating cells. In this context, mesenchymal stem cells and keratinocytes play a crucial role in tissue regeneration. In chronic wounds these processes are disturbed and cell viability is reduced. Hydroxyectoine (HyEc) is a membrane protecting osmolyte with protein and macromolecule stabilising properties. Adipose-derived stem cells (ASC) and keratinocytes were cultured with chronic wound fluid (CWF) and treated with HyEc. Proliferation was investigated using MTT test and migration was examined with transwell-migration assay and scratch assay. Gene expression changes of basic fibroblast growth factor (b-FGF), vascular endothelial growth factor (VEGF), matrix metalloproteinases-2 (MMP-2) and MMP-9 were analysed by quantitative real-time polymerase chain reaction (qRT-PCR). CWF significantly inhibited proliferation and migration of keratinocytes. Addition of HyEc did not affect these results. Proliferation capacity of ASC was not influenced by CWF whereas migration was significantly enhanced. HyEc significantly reduced ASC migration. Expression of b-FGF, VEGF, MMP-2 and MMP-9 in ASC, and b-FGF, VEGF and MMP-9 in keratinocytes was strongly induced by chronic wound fluid. HyEc enhanced CWF induced gene expression of VEGF in ASC and MMP-9 in keratinocytes. CWF negatively impaired keratinocyte function, which was not influenced by HyEc. ASC migration was stimulated by CWF, whereas HyEc significantly inhibited migration of ASC. CWF induced gene expression of VEGF in ASC and MMP-9 in keratinocytes was enhanced by HyEc, which might partly be explained by an RNA stabilising effect of HyEc.

Acute and chronic wound fluids influence keratinocyte function differently.

Wound healing requires a proper functioning of keratinocytes that migrate, proliferate and lead to a competent wound closure. Impaired wound healing might be due to a disturbed keratinocyte function caused by the wound environment. Basically, chronic wound fluid (CWF) differs from acute wound fluid (AWF). The aim of this study was to analyse the effects of AWF and CWF on keratinocyte function. We therefore investigated keratinocyte migration and proliferation under the influence of AWF and CWF using MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] test and scratch assay. We further measured the gene expression by qRT-PCR regarding growth factors and matrixmetalloproteinases (MMPs) involved in regeneration processes. AWF had a positive impact on keratinocyte proliferation over time, whereas CWF had an anti-proliferative effect. Keratinocyte migration was significantly impaired by CWF in contrast to an undisturbed wound closure under the influence of AWF. MMP-9 expression was strongly upregulated by CWF compared with AWF. Keratinocyte function was significantly impaired by CWF. An excessive induction of MMP-9 by CWF might lead to a permanent degradation of extracellular matrix and thereby prevent wounds from healing.

Incidence of chronic postsurgical pain (CPSP) after general surgery.

OBJECTIVE: This study investigated the incidence and determinants of chronic postsurgical pain (CPSP) in a general surgical patient population. DESIGN: This is a prospective cross-sectional study at a university-affiliated clinic/level 1 trauma center. Patients were followed at least 1 year postoperatively. By surgical discipline, procedures were 50% orthopedic/trauma, 33% general (abdominal/visceral), and 17% vascular. SETTING: All patients admitted during one year (N = 3020) were eligible. Exclusion criteria were cognitive impairment, communication/language barrier, nonoperative treatment, and refusal to participate. A CPSP questionnaire was completed. Step-by-step analysis followed with a 2(nd) questionnaire to detect CPSP with numeric rating scale (NRS) pain intensity ≥3. Finally, individual follow-up examinations were performed. RESULTS: 911 patients responded (30.2%). 522 complained of pain intensity ≥3 on NRS (scale 0-10). The second step identified 214 patients with chronic pain (NRS ≥3, mean 29 months postoperatively). On final examination, 83 CPSP patients (14.8%) were identified. By surgical discipline, 28% were general, 15% vascular, and 57% trauma/orthopedic surgery. Most oftenly cited pain sites were joint (49.4%), incisional/scar (37.7%), and nerve pain (33.7%). By procedure, patients underwent pelvic surgery, colon surgery, laparoscopies, inguinal herniorrhaphies, arthroscopies, and hardware extractions. All patients in the "laborer" and "unemployed" categories reported chronic pain. CONCLUSION: Bias due to study design and/or heterogeneity of patients is possible, but there was a high CPSP rate after 2 years both generally and particularly in orthopedic/trauma (57%) patients. Both "major" and "minor" surgical procedures led to CPSP.

George Gershwin -- a case of new ways in neurosurgery as well as in the history of Western music.

George Gershwin, the famous American composer, died in 1937 of a temporal lobe glioma. An emergency surgery was performed by R. Nafziger and W. E. Dandy. The case of George Gershwin indicates the beginning of a new era in music history as well as in the history of neurosurgery.

Correlation between Obesity and Socioeconomic and Psychological Characteristics of Students Attending Different Rural School Types.

We examined the prevalence of obesity in two types of schools-a comprehensive school and a grammar school-in a rural German region of Brandenburg. METHODS: In a cross-sectional study, BMI values were measured in 114 students in grades 5, 7, and 10. In addition to the demographic data, data on nutrition, physical activity, and mental well-being were collected using a questionnaire. RESULTS: A total of 44% (11/25) of the comprehensive school students and 15% (13/89) of the high school students are overweight, and 24% (6/25) of the comprehensive school pupils and 6% (5/89) of the grammar school pupils (p = 0.009) are obese. In addition, 91% (10/11) of the students with obesity, 36% (4/11) of the students with pre-obesity, and 31% (26/84) of the normal-weight students (p = 0.001) are concerned about their weight. Among the children with obesity, 82% (9/11) are afraid of gaining weight. In addition, 6% (5/82) of the normal-weight students, 25% (3/12) of the students with pre-obesity, and 70% (7/10) of the students with obesity feel restricted by their weight when exercising. CONCLUSION: School attendance and parental socioeconomic status appear to correlate with students' weight statuses. There is a high level of suffering, and they feel uncomfortable with their bodies and worry about weight regulation.

Interprofessional collaboration and patient-reported outcomes in inpatient care: a systematic review.

BACKGROUND: Interprofessional collaboration (IPC) is seen as the "gold standard" of comprehensive care, but credible evidence concerning the effects on patient-reported outcomes (PRO) is lacking. The aim of this systematic review is to study the effect of IPC on PRO in inpatient care. METHODS: We systematically searched six electronic databases (PubMed, Web of Science/Social Science Citation Index, CENTRAL (Cochrane Library), Current Contents (LIVIVO), CINAHL, and Embase) for studies published between 1997 and 2021. Additional studies were identified through citation tracking, manually searching the Internet and Google Scholar, and consultation of experts. Risk of bias (RoB) was assessed using the RoB 2 tool for randomized controlled trials (RCTs) and ROBINS-I for non-randomized studies (NRS). The included controlled before-and-after study (CBA) was assessed using both the ROBINS-I and the Effective Practice and Organization of Care (EPOC) quality criteria. Results were synthesized through narrative description, grouping, and thematic analysis of extracted data. RESULTS: The search yielded 10,213 records, from which 22 studies (16 RCTs, five NRS, and one CBA) fulfilled the inclusion criteria. In all but five studies, RoB was assessed as being high (RoB 2) resp. critical or serious (ROBINS-I). Within these 22 studies, nine inductively derived outcomes were assessed: (i) quality of life, (ii) coping, (iii) functional ability and health status, (iv) psychiatric morbidity, (v) pain, (vi) managing one's own health care, (vii) treatment success, (viii) satisfaction, and (ix) therapeutic relationship. While some studies do not report effect estimates, and some of the reported effects appear to be imprecisely estimated, the overall results indicate that IPC may affect PRO positively across all outcomes. CONCLUSIONS: Due to high clinical heterogeneity and high RoB, the question whether IPC affects PRO cannot be answered conclusively. Methodically rigorous studies are needed in order to answer the question of effectiveness of IPC. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42017073900.

Relationship between volume and outcome for gastroschisis: A systematic review.

BACKGROUND: Newborns with gastroschisis need surgery to reduce intestines into the abdominal cavity and to close the abdominal wall. Due to an existing volume-outcome relationship for other high-risk, low-volume procedures, we aimed at examining the relationship between hospital or surgeon volume and outcomes for gastroschisis. METHODS: We conducted a systematic literature search in Medline, Embase, CENTRAL, CINAHL and Biosis Previews in June 2021 and searched for additional literature. We included (cluster-) randomized controlled trials (RCTs) and prospective or retrospective cohort studies analyzing the relationship between hospital or surgeon volume and mortality, morbidity or quality of life. We assessed risk of bias of included studies using ROBINS-I and performed a systematic synthesis without meta-analysis and used GRADE for assessing the certainty of the evidence. RESULTS: We included 12 cohort studies on hospital volume. Higher hospital volume may reduce in-hospital mortality of neonates with gastroschisis, while the evidence is very uncertain for other outcomes. Findings are based on a low certainty of the evidence for in-hospital mortality and a very low certainty of the evidence for all other analyzed outcomes, mainly due to risk of bias and imprecision. We did not identify any study on surgeon volume. CONCLUSION: The evidence suggests that higher hospital volume reduces in-hospital mortality of newborns with gastroschisis. However, the magnitude of this effect seems to be heterogeneous and results should be interpreted with caution. There is no evidence on the relationship between surgeon volume and outcomes.

Early short-term inpatient psychotherapeutic treatment versus continued outpatient psychotherapy on psychosocial outcome: a randomized controlled trial in trauma patients.

BACKGROUND: Inpatient psychotherapeutic support has been shown to reduce mental health problems in severely injured patients. However, this effect mostly disappears after discharge. The aim of this study was to compare short-term inpatient versus continued long-term outpatient psychotherapeutic support. METHODS: Patients with at least two injuries of a combined Abbreviated Injury Scale Severity Score Index≥5 were included in the study. Of 862 screened patients, 113 met all inclusion criteria. They were randomly assigned to a short-term group (n=59), where only inpatient support was given, and a long-term group (n=54), with additional outpatient sessions. The cognitive behavioral treatment was standardized by a manual. Psychological assessment for depression, anxiety, and posttraumatic stress disorder (PTSD) was performed in written form at the time of inclusion, discharge, and 6 months, 12 months, and 18 months after trauma. RESULTS: Forty-one percent (n=46) of all patients completed follow-up visits. The results show that symptoms of depression, anxiety, and PTSD disappeared more often in the long-term group than in the short-term group 1 year after trauma. Differences nearly reach significance for anxiety (p=0.051) and PTSD (p=0.059). Twenty-one percent of the short-term group patients showed at least one mental health disorder compared with no patients in the long-term group 1 year after trauma (p=0.035). CONCLUSION: Psychotherapeutic support of severely injured patients seems to be more effective in reducing depression, anxiety, and PTSD if extended further into outpatient care. This conclusion should be considered preliminary because of the small number of study patients.
