Polypharmacy in older adults with human immunodeficiency virus infection compared with the general population

Background: The percentage of older HIV-positive patients is growing, with an increase in age-related comorbidities and concomitant medication. Objectives: To quantify polypharmacy and profile types of non-antiretroviral drugs collected at community pharmacies in 2014 by HIV-positive individuals on antiretroviral therapy and to compare these findings with those of the general population. Methods: HIV-positive patients (n=199) were compared with a group of patients from the general population (n=8, 172), aged between 50 and 64 years. The factors compared were prevalence of polypharmacy (=5 comedications with cumulative defined daily dose DDD] per drug over 180), percentage of patients who collected each therapeutic class of drug, and median duration for each drug class (based on DDD). Results were stratified by sex. Results: Polypharmacy was more common in HIV-positive males than in the male general population (8.9% vs 4.4%, P=0.010). Polypharmacy was also higher in HIV-positive females than in the female general population (11.3% vs 3.4%, P=0.002). Percentage of HIV-positive patients receiving analgesics, anti-infectives, gastrointestinal drugs, central nervous system (CNS) agents, and respiratory drugs was higher than in the general population, with significant differences between male populations. No differences were observed in proportion of patients receiving cardiovascular drugs. The estimated number of treatment days (median DDDs) were higher in HIV-positive males than in males from the general population for anti-infectives (32.2 vs 20.0, P<0.001) and CNS agents (238.7 vs 120.0, P=0.002). A higher percentage of HIV-positive males than males from the general population received sulfonamides (17.1% vs 1.5%, P, 0.001), macrolides (37.1% vs 24.9%, P=0.020), and quinolones (34.3% vs 21.2%, P=0.009). Conclusion: Polypharmacy is more common in HIV-positive older males and females than in similarly aged members of the general population. HIV-positive patients received more CNS drugs and anti-infectives, specifically sulfonamides, macrolides, and quinolones, but there were no differences in the percentage of patients receiving cardiovascular drugs. It is essential to investigate nonantiretroviral therapy medication use in the HIV-positive population to ensure these patients receive appropriate management

Drugs use in pregnancy in the Valencia Region and the risk of congenital anomalies

Background Despite the potential risks of drug use during pregnancy, consumption has increased in recent decades. Objective To identify the risk of congenital anomalies (CA) associated with the use of drugs in primary care in pregnant women resident in the Valencia Region. Methods A case-control study, considering a case as a less than one year old live birth in 2009–2010, diagnosed with a CA and resident in the Valencia Region, obtained from the CA population-based registry. Controls were selected from the Metabolic Disease Registry, and the drugs prescribed and dispensed from the Integral Management of Pharmaceutical Services. Crude odds ratio (OR) was calculated with its 95% confidence intervals and adjusted OR was calculated using logistic regression. Results A total of 1.913 cases and 3.826 controls were identified. The most frequently used drug groups were those acting on the musculoskeletal, nervous and respiratory systems, on the blood and blood forming organs, and anti-infection drugs. The most common drugs used were ibuprofen, dexketoprofen, paracetamol, amoxicillin, ferrous sulphate, and a combination of folic acid. A significantly increased risk of CA was identified for drugs acting on the musculoskeletal system (adjusted OR 1.14 [95% confidence interval 1.02–1.28]). A significantly decreased risk was observed for drugs acting on the blood and blood forming organs (adjusted OR 0.87 [95% confidence interval 0.78–0.98]). Conclusions Associations between drugs and CA in pregnant women resident in the Valencia Region have been identified for drugs that act as risk factors of CA, and for drugs that act as protective factors of CA. Antecedentes El consumo de medicamentos durante el embarazo se ha incrementado en las últimas décadas. Objetivo Identificar el riesgo de anomalías congénitas (AC) asociado a la utilización de medicamentos en atención ambulatoria en embarazadas residentes en la Comunitat Valenciana. Métodos Estudio de casos-controles, considerando caso a menores de un año nacidos vivos en 2009-2010 diagnosticados de AC y residentes en la Comunitat Valenciana, obtenidos del registro poblacional de AC. Los controles se seleccionaron del Registro de Metabolopatías y la medicación prescrita y dispensada se obtuvo del módulo Gestión Integral de Prestación Farmacéutica. Se calcularon las odds ratio (OR) y los intervalos de confianza al 95% y las OR ajustadas mediante regresión logística. Resultados Se identificaron 1.913 casos y 3.826 controles. Los grupos de medicamentos más frecuentemente prescritos y dispensados fueron: los que actúan sobre los sistemas musculoesquelético, nervioso, respiratorio, sobre la sangre y órganos hematopoyéticos, y antiinfecciosos. Los medicamentos más habituales fueron: ibuprofeno, dexketoprofeno, paracetamol, amoxicilina, sulfato de hierro y una combinación de ácido fólico. Se identificó un aumento del riesgo de anomalías congénitas significativo para los fármacos de acción sobre el sistema musculoesquelético (OR ajustada de 1,14 [intervalo de confianza al 95% 1,02-1,28]). Se observó una disminución del riesgo significativa en el grupo que actúa sobre la sangre y los órganos hematopoyéticos (OR ajustada de 0,87 [intervalo de confianza al 95% 0,78-0,98]). Conclusiones Se han identificado asociaciones de medicamentos con AC en mujeres embarazadas residentes en la Comunitat Valenciana, tanto para fármacos que actúan como factores de riesgo de AC como para fármacos que actúan como factores protectores de AC

La validez del Conjunto Mínimo Básico de Datos como fuente de identificación de las anomalías congénitas en la Comunitat Valenciana

Objetivo Evaluar la validez del Conjunto Mínimo Básico de Datos (CMBD) para identificar anomalías congénitas mayores en la Comunitat Valenciana. Métodos Se realizó un estudio epidemiológico retrospectivo. Del CMBD se seleccionaron las altas en menores de un año nacidos en 2007, residentes en la Comunitat Valenciana con código de anomalía congénita (740-759 CIE9-MC) y una muestra aleatoria de menores de un año sin altas con estos códigos. Tras revisar la documentación clínica, se clasificaron como verdaderos positivos y negativos y falsos positivos y negativos. Se calcularon el valor predictivo positivo y negativo y la sensibilidad. Se analizaron la concordancia de los diagnósticos entre el CMBD y la documentación clínica utilizando la prueba kappa. Resultados Se identificaron 2305 altas de 1651 pacientes. En los 544 pacientes de la muestra, 4 tenían alguna anomalía congénita mayor. El valor predictivo positivo fue del 56,4% (intervalo de confianza del 95% [IC95%]: 53,9-58,8) y el negativo fue del 99,3% (IC95%: 98,6-100,0). La sensibilidad del CMBD fue del 68,6% (IC95%: 66,1-71,1). Los códigos más frecuentes en los verdaderos positivos fueron: 745.5 (Comunicación interauricular), 745.4 (Comunicación interventricular) y 747.0 (Ductus arterioso persistente), y en los falsos positivos: 747.0, 745.5 y 752.51 (Criptorquidia). El 25,5% de los diagnósticos con anomalía congénita del CMBD no estaban en la historia clínica. Considerando todos los diagnósticos codificados en el CMBD, la concordancia fue de 0,70 (IC95%: 0,68-0,72). Conclusiones El CMBD es la principal fuente de información para la identificación de casos para el Registro Poblacional de Anomalías Congénitas de la Comunitat Valenciana, pero su principal limitación es el elevado número de casos falsos positivos que detecta. Objective To assess the validity of the Spanish Minimum Basic Data Set (MBDS) for identifying major congenital anomalies in the Valencian Community. Methods A retrospective epidemiological study was carried out. Children under the age of one year, born in 2007 and residing in the Valencian Community with congenital anomalies code 740-759 CIE9-MC, were selected from the MBDS, in addition to a random sample of children under the age of 1 year without these discharge codes. Having reviewed the clinical documentation, the cases were classified as true positives and negatives and false positives and negatives. Positive and negative predictive value and sensitivity were calculated. The kappa test was applied to analyse diagnostic consistency between the MBDS and the clinical documentation. Results A total of 2305 discharges of 1651 patients were identified. 4 out of the 5434 patients sampled had a major congenital abnormality. The positive predictive value was 56.4% (95% confidence interval [95%CI]: 53.9-58.8) and the negative predictive value was 99.3% (95%CI: 98.6-100.0). MBDS sensitivity was 68.6% (95%CI: 66.1-71.1). The most common codes in the true positives were: 745.5 (atrial septal defect), 745.4 (ventricular septal defect) and 747.0 (patent ductus arteriosus) and in the false positives: 747.0, 745.5 and 752.51 (cryptorchidism). 25.5% of diagnoses with congenital anomaly from the MBDS were not in the clinical documentation. Considering all diagnoses coded in the MBDS, the correlation was 0.70 (95%CI: 0.68-0.72) Conclusions The MBDS is the main source of information to detect cases in the registry of congenital anomalies of the Valencian Community. Its main limitation is the high number of false positive cases detected
