Objective: to discuss strategic challenges in complex health organizations sustained by an analysis in a Medical Genetics Center at a National Health Research Institute in Brazil., Method: Démarche Stratégique adapted for use with research institutes, including the policy formulation function. The study used institution's databases and workshops with key actors between Dec/2014 and Jun/2015., Results: Were defined the segments: clinical diagnosis, lysosomal diseases, osteogenesis imperfecta, genetic counseling, cytogenetics, biochemistry, and genomics. The findings reveal that the segments are aligned with the Institute's mission when it comes to referral care, although investment is required in strategic areas. The clinical diagnosis, lysosomal diseases, and genomics segments stood out in the scientific output portfolio. The findings show that progress needs to be made with policy implementation and planning to improve access to new technologies, together with investment in training and development, and the strengthening of coordination and collaboration between research institutes and referral services and between the wider healthcare network and research, care, and teaching. The inclusion of the policy formulation dimension was essential to highlight the unique role medical genetics plays in Brazil's public health system and the importance of developing action plans in the field of public health.

Objective: To describe the prevalence of hemoglobinopathies in the Brazilian adult population, according to laboratory tests from the National Health Survey., Methods: A descriptive study was carried out with National Health Survey laboratory data collected between 2014 and 2015. The hemoglobinopathies test was performed using the High Performance Liquid Chromatography method. The results of the individual tests were interpreted as providing normal, homozygous or heterozygous results for S, C and D hemoglobin, in addition to other possible hemoglobinopathies. Prevalence of hemoglobinopathies according to gender, skin color, region, age and schooling was estimated., Results: Hemoglobinopathies were present in 3.7% of the population. The main ones were the sickle cell trait (2.49%), thalassemia minor (0.30%) and suspected thalassemia major (0.80%). In relation to the sickle cell trait and suspected thalassemia major, there was a statistically significant difference for the skin color variable (p<0.05). The prevalences found for sickle cell trait according to skin color was: 4.1% among dark-skinned blacks, 3.6% among light-skinned blacks, 1.2% among whites, and 1.7% among others., Conclusion: The most prevalent hemoglobinopathies were the sickle cell trait and minor thalassemia, and were predominate among light- and dark-skinned black people. The study helps in identifying hemoglobinopathies and in genetic counseling in pre-conception.
