Comparison of public health and preventive medicine physician specialty training in six countries: Identifying challenges and opportunities.

RATIONALE: Public health and preventive medicine (PHPM) has been recognized internationally as a physician specialty, but national parallels and differences exist between training contexts. This paper reviews PHPM training and employment in Canada, France, Italy, Japan, the United Kingdom, and the USA. METHODS: Information gathered from relevant accreditation bodies and literature searches was used to create descriptive profiles of national training demographics and structure and a narrative outlining trends and challenges facing the specialty. RESULTS: Notable similarities and differences exist between national contexts. Key themes were differences in training strategies and practice scope, specialty stakeholders, certification structure, and funding. Recognition challenges faced the specialty across all six countries. Other challenges included unclear competencies and training strategies and a need for PHPM specialists to highlight their role in combating population health threats. Additional differences existed between comparator countries on the structure of training, funding sources for training programs, availability of training posts, and linkages with other physician specialties. CONCLUSION: Highlighting these themes is a first step to fostering training collaborations between PHPM specialist physicians to augment transnational action on global public health challenges and also supports PHPM physician educators with innovative solutions from abroad that might address domestic specialty challenges.

Socioeconomic status and stroke: an updated review.

BACKGROUND AND PURPOSE: Rates of stroke incidence and mortality vary across populations with important differences between socioeconomic groups worldwide. Knowledge of existing disparities in stroke risk is important for effective stroke prevention and management strategies. This review updates the evidence for associations between socioeconomic status and stroke. Summary of Review- Studies were identified with electronic searches of MEDLINE and EMBASE databases (January 2006 to July 2011) and reference lists from identified studies were searched manually. Articles reporting the association between any measure of socioeconomic status and stroke were included. CONCLUSIONS: The impact of stroke as measured by disability-adjusted life-years lost and mortality rates is >3-fold higher in low-income compared with high- and middle-income countries. The number of stroke deaths is projected to increase by >30% in the next 20 years with the majority occurring in low-income countries. Higher incidence of stroke, stroke risk factors, and rates of stroke mortality are generally observed in low compared with high socioeconomic groups within and between populations worldwide. There is less available evidence of an association between socioeconomic status and stroke recurrence or temporal trends in inequalities. Those with a lower socioeconomic status have more severe deficits and are less likely to receive evidence-based stroke services, although the results are inconsistent. Poorer people within a population and poorer countries globally are most affected in terms of incidence and poor outcomes of stroke. Innovative prevention strategies targeting people in low socioeconomic groups are required along with effective measures to promote access to effective stroke interventions worldwide.

Risk and cumulative risk of stroke recurrence: a systematic review and meta-analysis.

BACKGROUND AND PURPOSE: Estimates of risk of stroke recurrence are widely variable and focused on the short- term. A systematic review and meta-analysis was conducted to estimate the pooled cumulative risk of stroke recurrence. METHODS: Studies reporting cumulative risk of recurrence after first-ever stroke were identified using electronic databases and by manually searching relevant journals and conference abstracts. Overall cumulative risks of stroke recurrence at 30 days and 1, 5, and 10 years after first stroke were calculated, and analyses for heterogeneity were conducted. A Weibull model was fitted to the risk of stroke recurrence of the individual studies and pooled estimates were calculated with 95% CI. RESULTS: Sixteen studies were identified, of which 13 studies reported cumulative risk of stroke recurrence in 9115 survivors. The pooled cumulative risk was 3.1% (95% CI, 1.7-4.4) at 30 days, 11.1% (95% CI, 9.0-13.3) at 1 year, 26.4% (95% CI, 20.1-32.8) at 5 years, and 39.2% (95% CI, 27.2-51.2) at 10 years after initial stroke. Substantial heterogeneity was found at all time points. This study also demonstrates a temporal reduction in 5-year risk of stroke recurrence from 32% to 16.2% across the studies. CONCLUSIONS: The cumulative risk of recurrence varies greatly up to 10 years. This may be explained by differences in case mix and changes in secondary prevention over time However, methodological differences are likely to play an important role and consensus on definitions would improve future comparability of estimates and characterization of groups of stroke survivors at increased risk of recurrence.
