RESUMO
Avaliar os resultados clínicos de serviços de gerenciamento da terapia medicamentosa (GTM) oferecidos a pessoas vivendo com HIV (PVHIV) em uma unidade de dispensação de medicamentos brasileira. O estudo foi dividido em uma etapa transversal (etapa I), que avaliou o fator associado à identificação de dois ou mais problemas relacionados ao uso de medicamentos (PRM) na avaliação inicial; e uma etapa quasi- experimental (etapa II), realizada com um único grupo de pacientes para avaliar desfechos clínicosForam acompanhadas 52 PVHIV. A média de idade foi de 60±11,3 anos (min. = 29; máx. =78). A presença de dislipidemia (OR=5,38; IC 95%=1,61-17,97; p=0,006) e o uso de sete ou mais medicamentos (OR=4,28; IC 95%=1,32-13,88; p=0,015) foram fatores associados a identificação de dois ou mais PRM. Foi demonstrada uma diferença significativa entre os valores iniciais e finais de pressão arterial sistólica, carga viral do HIV, contagem de células T CD4+ e triglicerídeos (p<0,05). O serviço de GTM favoreceu os desfechos clínicos positivos.
To assess the clinical outcomes of comprehensive medication management (CMM) services offered to people living with HIV (PLHIV) at a Brazilian Antiretroviral Medication Dispensing Unit. The study was divided into a cross-sectional stage (stage I), to evaluate associated factor with the identification of two or more drug therapy problems (DTP) in the initial assessment; and a quasi-experimental stage (stage II), conducted with a single group of PLHIV to evaluate clinical outcomes. A total of 52 PLHIV, with 60±11.3 years of age were followed up. In stage I, the presence of dyslipidemia (OR=5.38; 95%CI=1.61-17.97) and the use of seven or more medications (OR=4.28; 95% CI=1.32-13.88) were factors associated with the identification of DTP. In stage II, a significant difference was demonstrated between the initial and final values of systolic blood pressure, triglycerides, HIV viral load and CD4+T-cells count (p<0,05). The CMM service favored positive clinical outcomes.
RESUMO
BACKGROUND: Acute kidney injury (AKI) is associated with a significant increase in morbidity, mortality, and health care costs. In intensive care units (ICU), AKI is commonly multifactorial and frequently involves diverse factors, such as hypovolemia, sepsis, and the use of nephrotoxic drugs. We aimed to investigate drug therapy and other factors associated with the development of AKI in a Brazilian public hospital. METHODS: This is a cross-sectional study involving critically ill patients at an ICU of a tertiary hospital. All data on sequential serum creatinine (SCr) level, glomerular filtration rate (GFR), and urine output were collected during ICU stay. The primary outcome was the occurrence of AKI assessed by the Acute Kidney Injury Network (AKIN) criterion. Sociodemographics, clinical data and drug therapy were considered as covariates. Factors associated with AKI were assessed using logistic regression. RESULTS: Overall, 122 participants were included in the study. Median age was 46.0 (interquartile range, IQ = 29.0-69.0) years, with a predominance of men (58.2%). Mean number of prescribed drugs throughout ICU stay was 22.0 ± 9.4. The number of potentially nephrotoxic drugs ranged from two to 24 per patient. A total of 29 (23.8%) ICU patients developed AKI. In the AKI-group, patients were older and showed higher Acute Physiology and Chronic Health Evaluation II (APACHE II) scores at admission, higher rates of sedation, mechanical ventilation, and infection. More drugs in general and specifically more vasoactive drugs were prescribed for AKI group. Patients who developed AKI tended to have extended stays in the ICU and a lower probability of being discharged alive than patients with no AKI development. Model adjustments of logistic regression showed that the number of medications (OR 1.15; 95% CI [1.05-1.27]) was the only factor associated with AKI in this study. This association was independent of drug nephrotoxicity. DISCUSSION: Intensive care is characterized by its complexity that combines unstable patients, severe diseases, high density of medical interventions, and drug use. We found that typical risk factors for AKI showed statistical association on bivariate analysis. The contribution of drug therapy in the occurrence of AKI in medical ICUs reinforces the need for prevention strategies focused on early recognition of renal dysfunction and interventions in drug therapy. These actions would help improve the quality of patient care and ensure progress towards medication safety.
RESUMO
: Hospitalized patients require the use of a variety of drugs, many of which individually or in combination have the potential to cause kidney damage. The use of potentially nephrotoxic drugs is often unavoidable, and the need for dose adjustment should be evaluated. This study is aimed at assessing concordance in information on drug-induced nephrotoxicity and dose adjustment recommendations by comparing four drug information sources (DRUGDEX(®), UpToDate(®), Medscape(®) and the Brazilian Therapeutic Formulary) using the formulary of a Brazilian public hospital. A total of 218 drugs were investigated. The global Fleiss' kappa coefficient was 0.265 for nephrotoxicity (p < 0.001; CI 95%, 0.211-0.319) and 0.346 for recommendations (p < 0.001; CI 95%, 0.292-0.401), indicating fair concordance among the sources. Anti-infectives and anti-hypertensives were the main drugs cited as nephrotoxic by the different sources. There were no clear definitions for qualitative data or quantitative values for dose adjustments among the four information sources. There was no advice for dosing for a large number of the drugs in the international databases. The National Therapeutic Formulary offered imprecise dose adjustment recommendations for many nephrotoxic drugs. Discrepancies among information sources may have a clinical impact on patient care and contribute to drug-related morbidity and mortality.
