Abstract
Real-world evidence (RWE) is emerging as a fundamental component of the post-marketing evaluation of medicinal products. Even though the focus on RWE studies has increased in Colombia, the availability of secondary data sources to perform this type of research is not well documented. Thus, we aimed at identifying and characterizing secondary data sources available in Colombia. We performed a systematic literature review on PubMed, EMBASE, and VHL using a combination of controlled vocabulary and keywords for the concepts of electronic health records, epidemiologic studies and Colombia. A total of 323 publications were included. These comprised 123 identified secondary data sources including pharmacy dispensing databases, government datasets, disease registries, insurance databases, and electronic heath records, among others. These data sources were mostly used for cross-sectional studies focused on disease epidemiology in a specific population. Almost all databases (95%) contained demographic information, followed by pharmacological treatment (44%) and diagnostic tests (39%). Even though the database owner was identifiable in 94%, access information was only available in 44% of the articles. Only a pharmacy-dispensing database, local cancer registries, and government databases included a description regarding the quality of the information available. The diversity of databases identified shows that Colombia has a high potential to continue enhancing its RWE strategy. Greater efforts are required to improve data quality and accessibility. The linkage between databases will expand data pooling and integration to boost the translational potential of RWE.

Abstract
We sought to develop individual-level Early Warning Indicators (EWI) of virologic failure (VF) for clinicians to use during routine care complementing WHO population-level EWI. A case-control study was conducted at a Durban clinic. Patients after ≥ 5 months of first-line antiretroviral therapy (ART) were defined as cases if they had VF [HIV-1 viral load (VL)>1000 copies/mL] and controls (2:1) if they had VL ≤ 1000 copies/mL. Pharmacy refills and pill counts were used as adherence measures. Participants responded to a questionnaire including validated psychosocial and symptom scales. Data were also collected from the medical record. Multivariable logistic regression models of VF included factors associated with VF (p<0.05) in univariable analyses. We enrolled 158 cases and 300 controls. In the final multivariable model, male gender, not having an active religious faith, practicing unsafe sex, having a family member with HIV, not being pleased with the clinic experience, symptoms of depression, fatigue, or rash, low CD4 counts, family recommending HIV care, and using a TV/radio as ART reminders (compared to mobile phones) were associated with VF independent of adherence measures. In this setting, we identified several key individual-level EWI associated with VF including novel psychosocial factors independent of adherence measures.

[Risk factors associated with virologic failure in HIV- infected patients receiving antiretroviral therapy at a public hospital in Peru]. Rev Chilena Infectol 2013; 30:42-8. [PMID: 23450408 DOI: 10.4067/s0716-10182013000100006] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2012] [Accepted: 11/17/2012] [Indexed: 10/27/2022] Open
Abstract
OBJECTIVE To describe clinical and biological characteristics of subjects with virologic failure who participated in the sexually transmitted diseases HIV/AIDS National Program from a Peruvian public hospital. MATERIALS AND METHODS An exploratory descriptive study was performed with data from subjects older than 18 who started high activity antiretroviral therapy (HAART) between May 2004 and December 2009 and who had a viral load control after 24 weeks of HAART. Virologic failure was defined as a viral load value above 1000 copies/mL on follow up after 24 weeks on HAART. RESULTS Of 1478 records of patients on HAART analyzed, the median age was 35 years [IQR, 29-41] and 69.6% were male. Also, virologic failure occurred in 24% and 3.7% died. Of subjects with virologic failure, 9.5% died. On multivariate analysis, age, history of antiretroviral use before starting HAART, change of antiretroviral therapy due to toxicity, opportunistic infections during HAART, level of CD4 + lymphocytes below 100 cells/ml at start of HAART, adherence and clinical stage were independently associated with virologic failure. In the group of patient with no history of antiretroviral use before starting HAART, age, opportunistic infections during HAART were associated with virologic failure. CONCLUSION This study identified factors associated with virologic failure. Further studies are needed to evaluate whether the use of these factors can help to identify prospectively patients at high risk of failure, and to design interventions aimed to reduce this risk.
