Association between glycemic control and albuminuria among Peruvian adults with diabetes mellitus 2: a cross-sectional analytical study

ABSTRACT BACKGROUND: Albuminuria is a risk factor for microvascular and macrovascular complications in the diabetic population. However, few studies have correlated poor glycemic control and albuminuria prevalence in Hispanic populations. OBJECTIVE: To evaluate the association between glycemic control and albuminuria among Peruvian adults with type 2 diabetes mellitus (T2DM). DESIGN AND SETTING: Cross-sectional analytical study among adults with T2DM in Lima, Peru. METHODS: We included adults over 18 years old who were in a clinical follow-up program at a private clinic in Lima in 2018. Poor glycemic control was defined as a serum value of glycosylated hemoglobin A1C (HbA1C) ≥ 7%. Albuminuria was defined as albumin values > 30 mg/dl in the first morning urine. We generated generalized linear regression models from the Poisson family with robust variance. We calculated the crude and adjusted prevalence ratios (PRs) with their 95% confidence interval (CI). RESULTS: We analyzed 907 participants of median age 58 years (interquartile range, IQR 49 to 66), and 62.8% were males. The prevalence of poor glycemic control was 39.8%, and the prevalence of albuminuria was 22.7%. The prevalences of albuminuria in groups with poor glycemic control and adequate glycemic control were 32.7% and 16.1%, respectively. In the adjusted regression analysis, we found a statistically significant association between poor glycemic control and albuminuria (annual percentage rate, aPR = 1.70; 95% CI: 1.28-2.27). CONCLUSIONS: The prevalence of poor glycemic control and albuminuria was high in our study population. Moreover, Peruvian T2DM adults with poor glycemic control were more likely to have albuminuria.

Factores epidemiológicos asociados a la referencia temprana al nefrólogo para hemodiálisis crónica en pacientes de un Hospital Público de Perú / Epidemiological factors associated with early referral to a nephrologist to start chronic hemodialysis in patients at a Public Hospital in Peru

OBJETIVO: El objetivo de esta investigación fue establecer la frecuencia de referencia temprana al nefrólogo para el inicio de hemodiálisis (HD) y sus factores epidemiológicos asociados en pacientes con enfermedad renal crónica (ERC) de un hospital público de Perú. MATERIAL Y MÉTODOS: Estudio observacional, analítico, de diseño transversal. El estudio fue llevado a cabo en pacientes que inician HD de un hospital público de Perú. La variable principal fue referencia temprana, definida como todo paciente que recibió indicación de inicio de HD después de 180 días de la primera atención en el servicio de nefrología. Se recolectaron variables epidemiológicas y de laboratorio. Se utilizó modelos lineales generalizados (MLG) crudo y ajustado; y como medida de asociación se calculó la razón de proporciones (PR) con intervalo de confianza (IC) al 95%. RESULTADOS: Se evaluaron 148 pacientes, se encontró referencia temprana en 17% de la población. En el MLG ajustado, los mayores de 60 años tuvieron mayor frecuencia de referencia temprana al nefrólogo PR= 2,17; IC 95% (1.09-4.32); p=0,03. Se encontró menor frecuencia de referencia temprana entre los participantes con anemia severa, PR=0,15; IC 95% (0,02-1,11); p=0,06. CONCLUSIONES: La frecuencia de referencia temprana es baja y debería considerarse como problema de salud pública; se recomienda mejorar los procesos de referencia de las redes de nuestra institución

OBJECTIVE: Our objective was to establish the frequency of early referral to the nephrologist for the initiation of hemodialysis (HD) and its associated epidemiological factors in patients with chronic kidney disease (CKD) in a public hospital in Peru. MATERIAL AND METHODS: We conducted an analytical cross-sectional study in patients who started HD in a public hospital in Peru. Our main variable was early referral, defined as patients who received an indication of onset of HD after 180 days of the first appointment in the nephrology service. We collected epidemiological and laboratory variables. We used crude and adjusted generalized linear models (GLM) and we calculated the proportion ratio (PR) with a 95% confidence interval (CI) as a measure of association. RESULTS: We evaluated 148 patients; we found early referral in 17% of the population. In the adjusted GLM, participants older than 60 years had a higher proportion of early referral to the nephrologist, PR = 2.17; 95% CI (1.09-4.32); p = 0.03. We showed a lower frequency of early referral among participants with severe anemia, PR = 0.15; 95% CI (0.02-1.11); p = 0.06. CONCLUSIONS: The frequency of early referral is low and it should be considered a public health problem. We recommend improving the process of referral in our health care network

Diferencias institucionales en el insuficiente acceso efectivo a medicamentos prescritos en instituciones prestadoras de servicios de salud en Perú: análisis de la Encuesta Nacional de Satisfacción de Usuarios de los Servicios de Salud (ENSUSALUD 2014) / Institutional differences in the ineffective access to prescription medication in health care centers in Peru: analysis of the National Survey on User Satisfaction of Health Services (ENSUSALUD 2014)

RESUMEN Objetivos Estimar la prevalencia de insuficiente acceso efectivo a medicamentos (IAEM) y sus factores asociados en usuariosque reciben prescripción médica en la consulta ambulatoria de instituciones prestadoras de servicios de salud (IPRESS) en Perú. Materiales y métodos Se realizó un análisis secundario de la Encuesta Nacional de Satisfacción de Usuarios en Salud (ENSUSALUD) del año 2014; estudio con muestreo probabilístico bietápico a nivel nacional en IPRESS del Ministerio de Salud y Gobiernos Regionales (MINSA-GR), Seguro Social de Salud (EsSalud), Fuerzas Armadas y Policiales (sanidades), y Clínicas del sector privado. El IAEM se definió como la dispensación incompleta o de ningún medicamento en la farmacia de la IPRESS. Se realizaron modelos lineales generalizados y se estimaron razones de prevalencia (RP) con IC 95% para muestreo complejo. Resultados De los 13 670 entrevistados, el 80,9% (IC 95%: 79,9-81,8%) recibieron indicación de medicamentos, y de éstos el 90,8% (IC 95%: 90,1-91,6%) los solicitaron en la farmacia de la IPRESS, donde el 30,6% (IC 95%:28,8-32,4%) tuvo IAEM. El ser atendido en el MINSA-GR (RP: 4,8; IC95%: 3,5-6,54) y en las sanidades (RP: 3,21; IC 95%: 2,3-4,5), el ser de la tercera edad (RP: 1,17; IC 95%: 1,04-1,34) y el pertenecer al quintil más pobre (RP: 1,21; IC 95%: 1,05-1,41) incrementaron la probabilidad de IAEM. Asimismo, los pacientes atendidos por una enfermedad de menos de 15 días (RP: 1,37; IC 95%: 1,05-1,79) y de 15 días a más (RP: 1,51; IC 95%: 1,16-1,97) tuvieron una mayor prevalencia de IAEM que aquellos atendidos por embarazo u otros controles. Conclusiones El IAEM está asociado al subsistema de salud, edad, pobreza y tipo de consulta realizada. Se sugieren implementar estrategias para fomentar el acceso a medicamentos en la población peruana.

ABSTRACT Objectives To estimate the prevalence of ineffective access to drugs (IAD) and associated factors in patients receiving a prescription in an outpatient clinic in Peru. Materials and Methods We performed a secondary data-analysis of the National Survey on User Satisfaction of Health Services (ENSUSALUD 2014), a two-stage population-based study carried out in health care centers of the Ministry of Health and Regional Governments (MOHRG), Social Security (EsSalud), Armed Forces and Police (AFP) and the private sector across all 25 regions of Peru. IAD was defined as incomplete or no dispensing of any prescribed medication in the health care center pharmacy. Generalized linear models with Poisson distribution for complex survey sampling were fit to estimate prevalence ratios (PR) and 95% confidence intervals (CI). Results Out of 13,360 participants, 80.9 % (95% CI: 79.9-81.8) had an active prescription, and of those, 90.8 % (95% CI: 90.1-91.6) sought their medications in a health care center pharmacy, where 30.6 % (95% CI 28.8-32.4) had IAD. In the multiple regression model, receiving medical attention in the MOHRG (PR 4.8; 95%CI: 3.5-6.54) or AFP (PR: 3.2; 95%CI: 2.3-4.5), being over 60 years old (PR: 1.17; 95%CI: 1.04-1.34) and being in the poorest income quintile (PR: 1.05; 95%CI: 1.05-1.41) increased IAD. Furthermore, in contrast to seeking care for pregnancy or other routine control, IAD was also more common for medical consultation for diseases diagnosed in the last 15 days (PR: 1.37; 95% CI: 1.05-1.79) or more than 15 days prior (PR: 1.51; 95% CI: 1.16-1.97). Conclusions In Peru, IAD is associated with the provider institution, older age, poverty and the reason for medical consultation. We suggest strategies to promote access to medicines, especially in the most disadvantaged segments of the Peruvian population.
