RESUMO
OBJECTIVE: To provide a basis for evaluating post-2007 alcohol policy in Scotland, this paper tests the extent to which pre-2007 policy, the alcohol market, culture or clinical changes might explain differences in the magnitude and trends in alcohol-related mortality outcomes in Scotland compared to England & Wales (E&W). STUDY DESIGN: Rapid literature reviews, descriptive analysis of routine data and narrative synthesis. METHODS: We assessed the impact of pre-2007 Scottish policy and policy in the comparison areas in relation to the literature on effective alcohol policy. Rapid literature reviews were conducted to assess cultural changes and the potential role of substitution effects between alcohol and illicit drugs. The availability of alcohol was assessed by examining the trends in the number of alcohol outlets over time. The impact of clinical changes was assessed in consultation with key informants. The impact of all the identified factors were then summarised and synthesised narratively. RESULTS: The companion paper showed that part of the rise and fall in alcohol-related mortality in Scotland, and part of the differing trend to E&W, were predicted by a model linking income trends and alcohol-related mortality. Lagged effects from historical deindustrialisation and socio-economic changes exposures also remain plausible from the available data. This paper shows that policy differences or changes prior to 2007 are unlikely to have been important in explaining the trends. There is some evidence that aspects of alcohol culture in Scotland may be different (more concentrated and home drinking) but it seems unlikely that this has been an important driver of the trends or the differences with E&W other than through interaction with changing incomes and lagged socio-economic effects. Substitution effects with illicit drugs and clinical changes are unlikely to have substantially changed alcohol-related harms: however, the increase in alcohol availability across the UK is likely to partly explain the rise in alcohol-related mortality during the 1990s. CONCLUSIONS: Future policy should ensure that alcohol affordability and availability, as well as socio-economic inequality, are reduced, in order to maintain downward trends in alcohol-related mortality in Scotland.

OBJECTIVE: This paper tests the extent to which differing trends in income, demographic change and the consequences of an earlier period of social, economic and political change might explain differences in the magnitude and trends in alcohol-related mortality between 1991 and 2011 in Scotland compared to England & Wales (E&W). STUDY DESIGN: Comparative time trend analyses and arithmetic modelling. METHODS: Three approaches were utilised to compare Scotland with E&W: 1. We modelled the impact of changes in income on alcohol-related deaths between 1991-2001 and 2001-2011 by applying plausible assumptions of the effect size through an arithmetic model. 2. We used contour plots, graphical exploration of age-period-cohort interactions and calculation of Intrinsic Estimator coefficients to investigate the effect of earlier exposure to social, economic and political adversity on alcohol-related mortality. 3. We recalculated the trends in alcohol-related deaths using the white population only to make a crude approximation of the maximal impact of changes in ethnic diversity. RESULTS: Real incomes increased during the 1990s but declined from around 2004 in the poorest 30% of the population of Great Britain. The decline in incomes for the poorest decile, the proportion of the population in the most deprived decile, and the inequality in alcohol-related deaths, were all greater in Scotland than in E&W. The model predicted less of the observed rise in Scotland (18% of the rise in men and 29% of the rise in women) than that in E&W (where 60% and 68% of the rise in men and women respectively was explained). One-third of the decline observed in alcohol-related mortality in Scottish men between 2001 and 2011 was predicted by the model, and the model was broadly consistent with the observed trends in E&W and amongst women in Scotland. An age-period interaction in alcohol-related mortality was evident for men and women during the 1990s and 2000s who were aged 40-70 years and who experienced rapidly increasing alcohol-related mortality rates. Ethnicity is unlikely to be important in explaining the trends or differences between Scotland and E&W. CONCLUSIONS: The decline in alcohol-related mortality in Scotland since the early 2000s and the differing trend to E&W were partly described by a model predicting the impact of declining incomes. Lagged effects from historical social, economic and political change remain plausible from the available data.

Methicillin-resistant Staphylococcus aureus (MRSA) is responsible for more than 40% of S. aureus bacteraemias in the UK and is associated with considerable morbidity and mortality. This retrospective audit examined the epidemiology of MRSA bacteraemia (MRSAB) at our institution, where the MRSAB rate has been high. A retrospective case note review was undertaken of all patients dying within 90 days of an episode of MRSAB during a 12-month period. A clinical panel classified deaths as having MRSAB as the main cause, contributing cause or having no bearing on the death. Sixty-two patients had one or more episodes of MRSAB and 30 died within 90 days. The mean age of those dying was 72 (43-96) years and of those surviving was 57 (21-87) years. MRSAB was judged to be the main or contributing cause of death in 24 cases, giving an associated mortality of 39%. All-cause mortality at 7, 30 and 90 days was 19, 40 and 48%, respectively. We investigated the minimum inhibitory contribution (MIC) to vancomycin for 79 MRSAB isolates, of which 70.8% of isolates had an MIC value of 2 mg/l. None of the isolates expressed heteroresistance to vancomycin. Five out of seven patients in whom MRSAB was the main cause of death had community onset of infection. It is unlikely that efforts to reduce delays in delivering effective antimicrobial therapy will have a major impact on mortality. Efforts to reduce the burden of MRSAB should focus on the primary prevention of bacteraemia.
