Although time target introduction is associated with changes in patient care, the introduction of a co-located MIU had greater impact.

A patient assessment score can be used by medical staff to raise awareness of the importance of a complete neurological examination from referring physicians.

Background Scotland was the first country to implement minimum unit pricing for alcohol nationally. Minimum unit pricing aims to reduce alcohol-related harms and to narrow health inequalities. Minimum unit pricing sets a minimum retail price based on alcohol content, targeting products preferentially consumed by high-risk drinkers. This study comprised three components. Objectives This study comprised three components assessing alcohol consumption and alcohol-related attendances in emergency departments, investigating potential unintended effects of minimum unit pricing on alcohol source and drug use, and exploring changes in public attitudes, experiences and norms towards minimum unit pricing and alcohol use. Design We conducted a natural experiment study using repeated cross-sectional surveys comparing Scotland (intervention) and North England (control) areas. This involved comparing changes in Scotland following the introduction of minimum unit pricing with changes seen in the north of England over the same period. Difference-in-difference analyses compared intervention and control areas. Focus groups with young people and heavy drinkers, and interviews with professional stakeholders before and after minimum unit pricing implementation in Scotland allowed exploration of attitudes, experiences and behaviours, stakeholder perceptions and potential mechanisms of effect. Setting Four emergency departments in Scotland and North England (component 1), six sexual health clinics in Scotland and North England (component 2), and focus groups and interviews in Scotland (component 3). Participants Research nurses interviewed 23,455 adults in emergency departments, and 15,218 participants self-completed questionnaires in sexual health clinics. We interviewed 30 stakeholders and 105 individuals participated in focus groups. Intervention Minimum unit pricing sets a minimum retail price based on alcohol content, targeting products preferentially consumed by high-risk drinkers. Results The odds ratio for an alcohol-related emergency department attendance following minimum unit pricing was 1.14 (95% confidence interval 0.90 to 1.44; p = 0.272). In absolute terms, we estimated that minimum unit pricing was associated with 258 more alcohol-related emergency department visits (95% confidence interval –191 to 707) across Scotland than would have been the case had minimum unit pricing not been implemented. The odds ratio for illicit drug consumption following minimum unit pricing was 1.04 (95% confidence interval 0.88 to 1.24; p = 0.612). Concerns about harms, including crime and the use of other sources of alcohol, were generally not realised. Stakeholders and the public generally did not perceive price increases or changed consumption. A lack of understanding of the policy may have caused concerns about harms to dependent drinkers among participants from more deprived areas. Limitations The short interval between policy announcement and implementation left limited time for pre-intervention data collection. Conclusions Within the emergency departments, there was no evidence of a beneficial impact of minimum unit pricing. Implementation appeared to have been successful and there was no evidence of substitution from alcohol consumption to other drugs. Drinkers and stakeholders largely reported not noticing any change in price or consumption. The lack of effect observed in these settings in the short term, and the problem-free implementation, suggests that the price per unit set (£0.50) was acceptable, but may be too low. Our evaluation, which itself contains multiple components, is part of a wider programme co-ordinated by Public Health Scotland and the results should be understood in this wider context. Future work Repeated evaluation of similar policies in different contexts with varying prices would enable a fuller picture of the relationship between price and impacts.

BackgroundWe have previously shown that providing more ophthalmoscopes and training does not necessarily increase Foundation Years level of confidence at using an ophthalmoscope. Thus we developed a simple scoring system as an indirect measure of the quality of neurological examination skills- the TOS score, ie asking the patient if they could recollect being examined with a Tendon hammer (T), Ophthalmoscope (O) and Stethoscope (S)- the latter as a measure of recall.MethodsWe assessed TOS scores in 59 in-patients referred for a neurological opinion in two NHS Trusts.ResultsIn Trust A (n=29)—27% of patients could not recall being examined with an ophthalmoscope, 11% could not recall being examined with a tendon hammer. In Trust B (n=30)—80% of patients could not recall ophthalmoscopy, 50% could not recall being examined with a tendon hammer. In both Trusts, only 3% of patients could not recall being examined with a stethosope.ConclusionsMeasurement of TOS scores on patients referred to neurology is a simple method of measurement of quality of in-patient neurological assessment. The results can be feedback to the referring team- we have provided feedback on TOS scores to all medical staff as part of an ongoing survey. Of greater concern, the TOS scores can show how ‘Neurology NAD’ in the notes may actually mean ‘Neurology not actually done’ which has important implications.

Modulating the abundance of the blood-brain barrier (BBB) efflux transporter breast cancer resistance protein (BCRP) has the potential to impact brain levels of drugs and endogenous substrates. Studies have demonstrated that the metal ionophore clioquinol (CQ) increases BBB abundance of P-glycoprotein (Pgp), an effect associated with increased endothelial cell levels of Cu 2þ . This study therefore assessed whether human brain endothelial (hCMEC/D3) cell abundance and function of BCRP is modulated by CQ. hCMEC/D3 cells were treated with CQ, Zn 2þ and Cu 2þ (CZC) (0.5 mM, 0.5 mM, 0.1 mM, respectively) for 24 h and BCRP mRNA and protein abundance was determined by Western blot and qPCR, respectively. After a series of optimisation studies assessing specificity of bodipy prazosin (BP) and Ko143 as a substrate and inhibitor of BCRP, respectively, the impact of CZC on BP uptake was assessed. While CZC did not increase mRNA expression of BCRP, BCRP abundance was increased 1.8 ± 0.1-fold; this was associated with a 68.1 ± 3.3% reduction in accumulation of BP in hCMEC/D3 cells. This is the first study to demonstrate that augmenting metal ion availability enhances protein abundance and function of BCRP at the BBB, which may be exploited to modulate CNS access of therapeutics and endogenous substrates.
