•Socioeconomic factors:
• gender
• age
• Income
•Propensity to seek care according to perceived health needs
•Hospital bed availability
•Regular source of care or continuity of care
•Differences in healthcare service (Public/Private healthcare; Insurances)
•Coding Issues
•Lack in Epidemiological Studies (or inconsistent)
•Intra-regional variations

Conclusions
•From 55 years old on:•There is a clear increase in avoidable hospitalizations•Males present higher avoidable hospitalizations rates
•Differences among years are not significant•Norte presents the best quality/cost ratio
•Portugal shows a more efficient primary healthcare system than USA or Spain.•Some heterogeneity among regions points to uneven primary healthcare supply•Further study is required to evaluate yearly trends and precise factors which influence PQ.

Future Research
• Multivariate analysis of correlations
• Litoral/Interior Analysis
• Wider timespan (Pre and Post SNS restructuration)
• Careful analysis of economical indexes and prevalence of
analysed conditions
• Further International Comparison
