    OBJETIVO: Implementar um programa hospitalar de profilaxia de TEV através da criação de uma comissão, da realização de palestras e da distribuição de algoritmos baseados na Diretriz Brasileira para Profilaxia de TEV em Pacientes Clínicos e avaliar seu impacto na adequação da utilização de profilaxia em quatro hospitais de Salvador, Bahia. MÉTODOS: Foram realizados dois estudos de corte-transversal, um antes e um depois da implementação do programa, e comparadas as proporções de pacientes em risco de TEV e as mudanças na adequação da profilaxia. RESULTADOS: Foram avaliados 219 pacientes clínicos antes e 292 depois do programa. As taxas daqueles com pelo menos um fator de risco para TEV e daqueles com contra indicação (CI) para heparina foram semelhantes nos dois grupos: 95% vs. 98% (p=0,13) e 42% vs. 34% (p=0,08), respectivamente. Nos dois estudos, 75% vs. 82% (p=0,06) eram candidates para profilaxia, e 44% vs. 55% (p =0,02) eram candidatos sem qualquer CI para heparina. Após o programa, utilizou-se mais profilaxia mecânica, 0,9% vs. 4,5% (p=0,03) e menos profilaxia farmacológica, 55,3% vs. 47,9% (p=0,04), embora tenha havido um aumento significativo na utilização das doses corretas das heparinas, 53% vs. 75% (pThere is a discrepancy between guideline recommendations and practice of venous thromboembolism (VTE) prophylaxis in hospitals worldwide. OBJECTIVE: To implement a program using a risk-assessment tool (RAT) for VTE and educational lectures based on the Brazilian Guidelines for VTE Prophylaxis for Medical Patients and to evaluate the impact of these tools on adequacy of VTE prophylaxis in 4 hospitals in Salvador, Bahia. METHODS: We performed two cross-sectional surveys before and after the implementation of the program to compare the proportion of patients at-risk of VTE and the changes in the adequacy of VTE prophylaxis. RESULTS: We compared the data of 219 medical patients before with 292 patients after the program. The rates of patients with at least one risk factor for VTE and with contraindications (CI) for heparins were similar: 95% vs. 98% (p=0.13), and 42% vs. 34% (p=0.08), respectively. In both studies, 75% vs. 82% (p=0.06) were candidates for prophylaxis, and 44% vs. 55% (p =0.02) were candidates for prophylaxis and had no CI for heparin. After the program there was an increase in the use of mechanical prophylaxis 0.9% vs. 4.5% (p=0.03) and a decrease in pharmacological prophylaxis, 55.3% vs. 47.9% (p=0.04). However, there was a significant increase of use of the recommended doses of heparins, 53% vs. 75 (p<0.001). CONCLUSION: There is underutilization of VTE prophylaxis in Brazilian hospitals. Strategies based on passive distribution of RAT and educational lectures were not sufficient to improve the practice of prophylaxis, but improved the adequacy of VTE prophylaxis in hospitalized patients

    Dynamics and determinants of SARS-CoV-2 RT-PCR testing on symptomatic individuals attending healthcare centers during 2020 in Bahia, Brazil

    RT-PCR testing data provides opportunities to explore regional and individual determinants of test positivity and surveillance infrastructure. Using Generalized Additive Models, we explored 222,515 tests of a random sample of individuals with COVID-19 compatible symptoms in the Brazilian state of Bahia during 2020. We found that age and male gender were the most significant determinants of test positivity. There was evidence of an unequal impact among socio-demographic strata, with higher positivity among those living in areas with low education levels during the first epidemic wave, followed by those living in areas with higher education levels in the second wave. Our estimated probability of testing positive after symptom onset corroborates previous reports that the probability decreases with time, more than halving by about two weeks and converging to zero by three weeks. Test positivity rates generally followed state-level reported cases, and while a single laboratory performed ~90% of tests covering ~99% of the state's area, test turn-around time generally remained below four days. This testing effort is a testimony to the Bahian surveillance capacity during public health emergencies, as previously witnessed during the recent Zika and Yellow Fever outbreaks
