Reviewing factors affecting the effectiveness of decentralised domestic wastewater treatment systems for phosphorus and pathogen removal
Environmental pollution and risks to human health can result from diffuse sources of pollution originating from decentralised wastewater treatment systems (DWTS). In particular phosphorus pollution can lead to eutrophication and the downgrading of the quality of water bodies, for example, under the Water Framework Directive (WFD) in the EU, and pathogen pollution can result in increased risks of human exposure to pathogens and impacts on industries such as shellfish growing and tourism. The study reported in this paper reviews the effectiveness of various DWTS in removing phosphorus and pathogens from onsite systems. It was found that DWTS are typically not designed to specifically treat these pollutants and the most common type of DWTS, septic tanks, provide only basic treatment. Additional treatment such as filtration-based or wetland systems must be used to achieve desired levels of treatments. The performance of these systems is affected by site specific conditions, such as input load and sources, and climatic conditions and as such operational characteristics and treatment measures must be designed to take account of these factors
Investigating the removal of some pharmaceutical compounds in hospital wastewater treatment plants operating in Saudi Arabia
The concentrations of 12 pharmaceutical compounds (atenolol, erythromycin, cyclophosphamide, paracetamol, bezafibrate, carbamazepine, ciprofloxacin, caffeine, clarithromycin, lidocaine, sulfamethoxazole and Nacetylsulfamethoxazol (NACS)) were investigated in the influents and effluents of two hospital wastewater treatment plants (HWWTPs) in Saudi Arabia. The majority of the target analytes were detected in the influent samples apart from bezafibrate, cyclophosphamide, and erythromycin. Caffeine and paracetamol were detected in the influent at particularly high concentrations up to 75 and 12 ug/L, respectively. High removal efficiencies of the pharmaceutical compounds were observed in both HWWTPs, with greater than 90 % removal on average. Paracetamol, sulfamethoxazole, NACS, ciprofloxacin, and caffeine were eliminated by between >95 and >99 % on average. Atenolol, carbamazepine, and clarithromycin were eliminated by >86 % on average. Of particular interest were the high removal efficiencies of carbamazepine and antibiotics that were achieved by the HWWTPs; these compounds have been reported to be relatively recalcitrant to biological treatment and are generally only partially removed. Elevated temperatures and high levels of sunlight were considered to be the main factors that enhanced the removal of these compounds
Can nudge-interventions address health service overuse and underuse? Protocol for a systematic review
IntroductionNudge-interventions aimed at health professionals are proposed to reduce the overuse and underuse of health services. However, little is known about their effectiveness at changing health professionals’ behaviours in relation to overuse or underuse of tests or treatments.ObjectiveThe aim of this study is to systematically identify and synthesise the studies that have assessed the effect of nudge-interventions aimed at health professionals on the overuse or underuse of health services.Methods and analysisWe will perform a systematic review. All study designs that include a control comparison will be included. Any qualified health professional, across any specialty or setting, will be included. Only nudge-interventions aimed at altering the behaviour of health professionals will be included. We will examine the effect of choice architecture nudges (default options, active choice, framing effects, order effects) and social nudges (accountable justification and pre-commitment or publicly declared pledge/contract). Studies with outcomes relevant to overuse or underuse of health services will be included. Relevant studies will be identified by a computer-aided search of the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library), MEDLINE, CINAHL, Embase and PsycINFO databases. Two independent reviewers will screen studies for eligibility, extract data and perform the risk of bias assessment using the criteria recommended by the Cochrane Effective Practice and Organisation of Care (EPOC) group. We will report our results in a structured synthesis format, as recommended by the Cochrane EPOC group.Ethics and disseminationNo ethical approval is required for this study. Results will be presented at relevant scientific conferences and in peer-reviewed literature
Evaluation of a New Recombinant K39 Rapid Diagnostic Test for Sudanese Visceral Leishmaniasis.
A new rK39 rapid diagnostic dipstick test (DiaMed-IT-Leish) was compared with aspiration and a direct agglutination test (DAT) for diagnosis of visceral leishmaniasis (VL) in 201 parasitologically confirmed cases, 133 endemic controls, and in 356 clinical suspects in disease-endemic and -epidemic areas in Sudan. The sensitivity of the rK39 test in parasitologically confirmed VL cases was 90%, whereas the specificity in disease-endemic controls was 99%. The sensitivity of the DAT was 98%. In clinically suspected cases, the sensitivity of the rK39 test was 81% and the specificity was 97%. When compared with the diagnostic protocol based on the DAT and aspiration used by Médecins sans Frontières in epidemic situations, the positive predictive value was 98%, and the negative predictive value was 71%. This rK39 rapid diagnostic test is suitable for screening as well as diagnosis of VL. Further diagnostic work-up of dipstick-negative patients with clinically suspected VL is important. The ease and convenience of the dipstick test will allow decentralization and improved access to care in disease-endemic areas in Sudan

The value of emergency medicine placements for postgraduate doctors: views of Foundation Year 2 doctors and training leads in the emergency department (ED)
Objectives: To examine the delivery of postgraduate training in the emergency medicine setting and its impact on postgraduate doctor (Foundation Year 2) performance and competence.
Methods: A national study in four emergency departments (EDs) in England between 2009 and 2010 was undertaken. Semistructured interviews with ED training leads (TLs) and focus groups with Foundation Year 2 (F2) doctors were carried out in each ED. Interviews and focus group data were analysed to compare the perspectives of F2 doctors and TLs on the delivery of training and performance and confidence of F2 doctors.
Results: Interviews were carried out with eight TLs and focus groups with 30 F2s. F2 doctors and EDTLs agreed that ED was a valuable environment for F2 doctors to develop their competence, with exposure to a broad range of patients and the opportunity to make decisions about clinical care. Diverging views existed around competence and performance of F2s. F2 doctors had anxieties about decision-making (particularly discharging patients) and required regular feedback to feel confident in their care. TLs recognised a need for more supervision and support for F2 doctors but this was challenging in a busy, performance-led service.
Conclusions: Emergency medicine placements were important in the development of confident and competent F2 doctors, particularly in the context of less clinical exposure in other specialty placements. However, there are competing tensions between elements of postgraduate learning and service delivery within emergency medicine that require addressing to enable trainees to optimally develop knowledge and skills in this environment
Characterising non-urgent users of the emergency department (ED): A retrospective analysis of routine ED data
Background
The pressures of patient demand on emergency departments (EDs) continue to be reported
worldwide, with an associated negative impact on ED crowding and waiting times. It has
also been reported that a proportion of attendances to EDs in different international systems
could be managed in settings such as primary care. This study used routine ED data to
define, measure and profile non-urgent ED attendances that were suitable for management
in alternative, non-emergency settings.
Methods
We undertook a retrospective analysis of three years of Hospital Episode and Statistics
Accident Emergency (HES A&E) data for one large region in England, United Kingdom
(April 1st 2011 to March 31st 2014). Data was collected on all adult (>16 years) ED attendances
from each of the 19 EDs in the region. A validated process based definition of nonurgent
attendance was refined for this study and applied to the data. Using summary statistics
non-urgent attenders were examined by variables hypothesised to influence them as follows:
age at arrival, time of day and day of week and mode of arrival. Odds ratios were
calculated to compare non-urgent attenders between groups.
Results
There were 3,667,601 first time attendances to EDs, of which 554,564 were defined as nonurgent
(15.1%). Non-urgent attendances were significantly more likely to present out of
hours than in hours (OR = 1.19, 95% CI: 1.18 to 1.20, P<0.001). The odds of a non-urgent
attendance were significantly higher for younger patients (aged 16–44) compared to those
aged 45–64 (odds ratio: 1.42, 95% CI: 1.41 to 1.43, P<0.001) and the over 65’s (odds ratio:
3.81, 95% CI: 3.78 to 3.85, P<0.001). Younger patients were significantly more likely to
attend non-urgently out of hours compared to the 45–64’s (OR = 1.24, 95% CI: 1.22 to 1.25,
P<0.001) and the 65+’s (OR = 1.38, 95% CI: 1.35 to 1.40, P<0.001). 110,605/554,564 (19.9%) of the non-urgent attendances arrived by ambulance, increasing significantly out of
hours versus in hours (OR = 2.12, 95% CI: 2.09 to 2.15, P<0.001).
Conclusions
Younger adults are significantly more likely as older counterparts to use the ED to obtain
healthcare that could be provided in a less urgent setting and also more likely to do this out
of hours. Alternative services are required to manage non-urgent demand, currently being
borne by the ED and the ambulance service, particularly in out of hours

A data-linkage study of suspected seizures in the urgent and emergency care system in the UK
Introduction
The urgent and emergency care system (UEC) is struggling with increased demand, some of which is clinically unnecessary. Patients suffering suspected seizures commonly present to emergency departments, but most seizures are self-limiting and have low risk of short-term adverse outcomes. We aimed to investigate the flow of suspected seizure patients through the UEC system using datalinkage to facilitate development of new models of care.
Methods
We used a two-stage process of deterministic linking to perform a cross-sectional analysis of data from adults in a large region in England (population 5.4 million) during 2014. The core dataset
comprised a total of 739,436 ambulance emergency incidents, 1,033,778 ED attendances and 362,358 admissions.
Results
A high proportion of cases were successfully linked (86.9% ED-inpatient, 77.7% ED-ambulance). Suspected seizures represented 2.8% of all ambulance service incidents. 61.7% of these incidents led to dispatch of a rapid-response ambulance (8 minutes) and 72.1% were conveyed to hospital. 37 patients died before being conveyed to hospital and 24 died in the ED (total 61; 0.3%). The in-patient death rate was 0.4%. Suspected seizures represented 0.71% of ED attendances, 89.8% of these
arrived by emergency ambulance, 45.4% were admitted and 44.5% of these admissions lasted under 48 hours.
Conclusions
This study confirms previously published data from smaller unlinked datasets, validating the linkage method, and provides new data for suspected seizures. There are significant barriers to realising the full potential of data-linkage. Collaborative action is needed to create facilitative governance frameworks and improve data quality and analytical capacity
