Abstract Background: Despite being considered as a low prevalence country for hepatitis B (HBV), some populations in Germany are at higher risk of infection. In the context of the World Health Organization’s (WHO) viral hepatitis elimination goals a valid epidemiological data base is needed to plan and monitor the national response. Prevention strategies include general and targeted HBV vaccination programmes. Objective: The aim of this work was to estimate the HBV vaccination coverage (VC) in the general population (GP) and different population groups in Germany from available evidence and to identify current evidence gaps for future research.Methods: We conducted a systematic review on HBV VC in the general population and populations at high risk of HBV exposure or severe infection in Germany. We included eligible publications (01/01/2017 to 06/06/2020) from databases Embase, Pubmed and Livivo, from a previous scoping review (including data published 01/01/2005-17/03/2017), from the national surveillance system and screened the reference lists of all publications at full text level. Risk of bias was assessed using the Hoy et al tool. Results: We included 68 publications of 67 studies and assigned them to the respective population groups. Twenty-one studies contained data among children/adolescents and three among adults from the GP (VC 65.8% - 90.5% and 22.9% - 52.1%, respectively), one among travellers to HBV endemic countries (VC 89%), 13 among immunocompromised populations (VC 11.5% - 89%), 16 among populations with occupational risk and 16 with non-occupational risk of HBV exposure (VC 63.6% - 96.5% and 4.4% - 52%, respectively). Conclusion: Comprehensive evidence at low risk of bias was identified for children/adolescents. owever, 25 years after including HBV in the national immunisation schedule, VC in Germany is still below the 95%-goal defined by WHO. For people at occupational risk of HBV exposure, VC was mostly reported to be over the WHO goal of 80%, but quality of evidence was heterogenous and should be improved. For people at non-occupational risk of HBV exposure, evidence was sparse and of low quality. The low VC highlights the need for future research to plan vaccination programmes targeting these populations.

Twenty-one studies contained data among children/adolescents and three among adults from the GP (VC 65.8–90.5% and 22.9–52.1%, respectively), one among travelers (VC 89.0%), 13 among immunocompromised populations (VC 7.8–89.0%), 16 among populations with occupational risk and 16 with non-occupational risk of HBV exposure (VC 63.6–96.5% and 4.4–84.5%, respectively). Conclusion Comprehensive evidence at low risk of bias was identified for children/adolescents. However, 25 years after including HBV in the national immunisation schedule, VC in Germany is still below the 95%-goal defined by WHO.

Police, ambulance and mental health tri-response services are a relatively new model of responding to people experiencing mental health crisis in the community, but limited evidence exists examining their efficacy. To date there have been no systematic reviews that have examined the association between the tri-response model and rates of involuntary detentions. A systematic review examining co-response models demonstrated possible reduction in involuntary detention, however, recommended further research. The aim of this protocol is to describe how we will systematically review the evidence base around the relationship of the police, ambulance mental health tri-response models in reducing involuntary detentions. We will search health, policing and grey literature databases and include clinical evaluations of any design. Risk of bias will be determined using the Effective Public Health Practice Project Quality Assessment Tool and a narrative synthesis will be undertaken to synthesis key themes. Risk of bias and extracted data will be summarized in tables and results synthesis tabulated to identify patterns within the included studies. The findings will inform future research into the effectiveness of tri-response police, ambulance, and mental health models in reducing involuntary detentions.

Digital Surveillance

Abstract Background Nocturnal digital surveillance technologies are being widely implemented as interventions for remotely monitoring elderly populations, and often replace person-based surveillance. Such interventions are often placed in care institutions or in the home, and monitored by qualified personnel or relatives, enabling more rapid and/or frequent assessment of the individual’s need for assistance than through on-location visits. This systematic review summarized the effects of these surveillance technologies on health, welfare and social care provision outcomes in populations ≥ 50 years, compared to standard care. Method Primary studies published 2005–2020 that assessed these technologies were identified in 11 databases of peer-reviewed literature and numerous grey literature sources. Initial screening, full-text screening, and citation searching steps yielded the studies included in the review. The Risk of Bias and ROBINS-I tools were used for quality assessment of the included studies. Result Five studies out of 744 identified records met inclusion criteria. Health-related outcomes (e.g. accidents, 2 studies) and social care outcomes (e.g. staff burden, 4 studies) did not differ between interventions and standard care. Quality of life and affect showed improvement (1 study each), as did economic outcomes (1 study). The quality of studies was low however, with all studies possessing a high to critical risk of bias. Conclusions We found little evidence for the benefit of nocturnal digital surveillance interventions as compared to standard care in several key outcomes. Higher quality intervention studies should be prioritized in future research to provide more reliable evidence.

AbstractComputed tomographic pulmonary angiography (CTPA) is the gold standard for pulmonary embolism (PE) diagnosis. However, this diagnosis is susceptible to misdiagnosis. In this study, we aimed to perform a systematic review of current literature applying deep learning for the diagnosis of PE on CTPA. MEDLINE/PUBMED were searched for studies that reported on the accuracy of deep learning algorithms for PE on CTPA. The risk of bias was evaluated using the QUADAS-2 tool. Pooled sensitivity and specificity were calculated. Summary receiver operating characteristic curves were plotted. Seven studies met our inclusion criteria. A total of 36,847 CTPA studies were analyzed. All studies were retrospective. Five studies provided enough data to calculate summary estimates. The pooled sensitivity and specificity for PE detection were 0.88 (95% CI 0.803–0.927) and 0.86 (95% CI 0.756–0.924), respectively. Most studies had a high risk of bias. Our study suggests that deep learning models can detect PE on CTPA with satisfactory sensitivity and an acceptable number of false positive cases. Yet, these are only preliminary retrospective works, indicating the need for future research to determine the clinical impact of automated PE detection on patient care. Deep learning models are gradually being implemented in hospital systems, and it is important to understand the strengths and limitations of these algorithms.

SUMMARYIn Australia, hepatitis B (HBV) vaccination is recommended for injecting drug users (IDUs), Indigenous adults and prisoners. We compared immunity to HBV in prisoners and the general population obtained from national serosurveys in 2007. Individuals with HBV surface antibody (HBsAb) positive sera were considered immune from past infection [HBV core antibody (HBcAb) positive] or from vaccination (HBcAb negative). Male prisoners aged 18–58 years had a higher HBsAb seroprevalence than the general population (46·4% vs. 39·4%, P = 0·061). Comparison of HBcAb results was possible for males aged 18–29 years. In this group, higher HBsAb seroprevalence was due to past infection (12·9% vs. 3·0%, P < 0·001), rather than vaccine-conferred immunity (35·3% vs. 43·4%, P = 0·097). All prisoner groups, but especially IDUs, those of Indigenous heritage or those with a previous episode of imprisonment had higher levels of immunity from past infection than the general population (19·3%, 33·0%, 17·1%, respectively, vs. 3·0%, P < 0·05). Indigenous prisoners, non-IDUs and first-time entrants had significantly lower levels of vaccine-conferred immunity than the general population (26·4%, 26·2% and 20·7% respectively vs. 43·4%, P < 0·05). Improving prison-based HBV vaccination would prevent transmission in the prison setting and protect vulnerable members of the community who are at high risk of both infection and entering the prison system.

Background/objectives: A systematic review was conducted to assess if frailty and sarcopenia were associated with poorer outcomes in older adults admitted to an acute medical unit (AMU). Methods: Eligible studies included older adults with an unplanned admission to an AMU and included a measure of frailty or sarcopenia, completed within 72 hours of admission. Risk of bias was assessed. Results: Of 1659 identified articles, 16 were included (4 on sarcopenia and 12 on frailty). There was significant study heterogeneity. Overall, frailty and sarcopenia were associated with worse outcomes. Targeted interventions appeared to improve outcomes. Conclusion: Current evidence suggests some benefit in screening older adults admitted to an AMU for frailty and sarcopenia. However, further studies are required before clinical adoption.

ObjectivesWeight loss is commonly recommended for gout, but the magnitude of the effect has not been evaluated in a systematic review. The aim of this systematic review was to determine benefits and harms associated with weight loss in overweight and obese patients with gout.MethodsWe searched six databases for longitudinal studies, reporting the effect of weight loss in overweight/obese gout patients. Risk of bias was assessed using the tool Risk of Bias in Non-Randomised Studies of Interventions. The quality of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation.ResultsFrom 3991 potentially eligible studies, 10 were included (including one randomised trial). Interventions included diet with/without physical activity, bariatric surgery, diuretics, metformin or no intervention. Mean weight losses ranged from 3 kg to 34 kg. Clinical heterogeneity in study characteristics precluded meta-analysis. The effect on serum uric acid (sUA) ranged from −168 to 30 μmol/L, and 0%–60% patients achieving sUA target (<360 μmol/L). Six out of eight studies (75%) showed beneficial effects on gout attacks. Two studies indicated dose–response relationship for sUA, achieving sUA target and gout attacks. At short term, temporary increased sUA and gout attacks tended to occur after bariatric surgery.ConclusionsThe available evidence is in favour of weight loss for overweight/obese gout patients, with low, moderate and low quality of evidence for effects on sUA, achieving sUA target and gout attacks, respectively. At short term, unfavourable effects may occur. Since the current evidence consists of a few studies (mostly observational) of low methodological quality, there is an urgent need to initiate rigorous prospective studies (preferably randomised controlled trials).Systematic review registrationPROSPERO, CRD42016037937.

AbstractObjectiveTo synthesize the existing evidence base of systematic reviews of interventions to improve healthcare worker (HCW) hand hygiene compliance (HHC).MethodsPRISMA guidelines were followed, and 10 information sources were searched in September 2017, with no limits to language or date of publication, and papers were screened against inclusion criteria for relevance. Data were extracted and risk of bias was assessed.ResultsOverall, 19 systematic reviews (n=20 articles) were included. Only 1 article had a low risk of bias. Moreover, 15 systematic reviews showed positive effects of interventions on HCW HHC, whereas 3 reviews evaluating monitoring technology did not. Findings regarding whether multimodal rather than single interventions are preferable were inconclusive. Targeting social influence, attitude, self-efficacy, and intention were associated with greater effectiveness. No clear link emerged between how educational interventions were delivered and effectiveness.ConclusionsThis is the first systematic review of systematic reviews of interventions to improve HCW HHC. The evidence is sufficient to recommend the implementation of interventions to improve HCW HHC (except for monitoring technology), but it is insufficient to make specific recommendations regarding the content or how the content should be delivered. Future research should rigorously apply behavior change theory, and recommendations should be clearly described with respect to intervention content and how it is delivered. Such recommendations should be tested for longer terms using stronger study designs with clearly defined outcomes.

Abstract The aim of this study was to provide an overview of interventions targeting hospital care of patients with dementia. We conducted a systematic review, including interventional study designs. We searched five electronic databases, conducted a hand search and performed citation tracking. To assess risk of bias, we used Cochrane Collaboration’s tool, ROBANS and AMSTAR. We narratively summarized the outcomes.The findings of twenty studies indicated a broad range of interventions and outcomes. We categorised the interventions into eight intervention types. Educational programmes were the most reported intervention type and resulted in improved staff outcomes. Family-/person-centred care programmes, use of specially trained nurses and delirium management programmes were effective in improving patient-related outcomes. However, current evidence is insufficient to declare which interventions are effective in improving dementia care in acute hospitals. Future research should focus on relevant patient and family caregiver outcomes and must to consider the complexity of the interventions. Trial registration: PROSPERO: CRD42018111032.
