Which Factors may reduce the Health-Related Quality of Life of Ecuadorian Patients with Diabetes?

OBJECTIVE: To quantify the health-related quality of life (HRQoL) of patients with type 2 diabetes mellitus (DM) in Ecuador and to determine its association, or lack thereof, with demographic and clinical variables, particularly with the comorbidities and complications of DM. METHODS: This was an analytical cross-sectional study with 325 patients attending regular care at a primary health care center in Quito, Ecuador. HRQoL was measured using the EuroQol 5-dimension 3-level (EQ-5D-3L) questionnaire. The patients were screened for diabetic nephropathy, retinopathy, and peripheral artery disease (PAD). Clinical files were reviewed to obtain data regarding gender, age, time since diagnosis, type of treatment, glycemic control, and history (if any) of hypertension and/or dyslipidemia. Associations were verified using the Mann-Whitney U or Kruskal-Wallis test, and the confounding effects of the variables "age" and "gender" were controlled for using logistic regression analysis. RESULTS: The mean HRQoL for the population was 0.844 (±0.215) on the EQ-5D-3L index (EQ-Index) and 80.6 (±18.8) on the EQ visual analogue scale (EQ-VAS). The prevalence of DM complications was 1.8% for nephropathy, 14.8% for retinopathy, and 14.5% for PAD. Of the participating patients, 66.8% presented hypertension and 91.4%, dyslipidemia. Significant associations were found between lower scores on the EQ-Index and age (≥65 years) (0.84 vs. 0.87; p = 0.016), time since diagnosis (≥10 years) (0.81 vs. 0.87; p = 0.005), presence of hypertension (0.83 vs. 0.88; p = 0.017), and, after controlling for age and gender, presence of nephropathy. For the EQ-VAS, only time since diagnosis (≥10 years) was associated with a lower score (77.99 vs. 82.97; p = 0.043). CONCLUSION: Older age, longer disease duration, hypertension, and nephropathy are associated with having a lower HRQoL, in patients with type 2 DM in Quito, Ecuador.

Mental health determines the quality of life in patients with cancer-related neuropathic pain in Quito, Ecuador, / La salud mental determina la calidad de vida de los pacientes con dolor neuropático oncológico en Quito, Ecuador

Abstract Objective: To identify the main factors determining the health related quality of life (HRQL) in patients with cancer-related neuropathic pain in a tertiary care hospital. Methods: A cross-sectional analytical study was performed on a sample of 237 patients meeting criteria for cancer-related neuropathic pain. Clinical and demographic variables were recorded including, cancer type, stage, time since diagnosis, pain intensity, physical functionality with the palliative performance scale (PPS), and anxiety and depression with the hospital anxiety and depression scale (HADS). Their respective correlation coefficients (r) with HRQL assessed with the SF-36v2 Questionnaire were then calculated. Linear regression equations were then constructed with the variables that showed an r > 0.5 with the HRQL. Results: The HRQL scores of the sample were 39.3 ± 9.1 (Physical Component) and 45.5 ± 13.8 (Mental Component). Anxiety and depression strongly correlated with the mental component (r = -0.641 and r = -0.741, respectively) while PPS score correlated with the physical component (r = 0.617). The linear regression model that better explained the variance of the mental component was designed combining the Anxiety and Depression variables (r = 77.3%; p < 0.001). Conclusions: The strong influence of psychiatric comorbidity on the HRQL of patients with cancer-related neuropathic pain makes an integral management plan essential for these patients to include interventions for its timely diagnosis and treatment.

Resumen Objetivo: Identificar los principales determinantes de la calidad de vida relacionada con la salud (CVRS) de pacientes con dolor neuropático oncológico en un hospital de tercer nivel de atención. Métodos: Estudio transversal analítico. En una muestra de 237 pacientes con criterios de dolor neuropático de origen oncológico, se midieron variables clínico-demográficas: tipo de cáncer, estadio, tiempo de diagnóstico, intensidad del dolor, funcionalidad física con la escala PPS, y ansiedad y depresión con la escala HADS. Se calcularon sus respectivos coeficientes de correlación (r) con la CVRS medida con el cuestionario SF-36v2TM. Con las variables que mostraron r > 0,5 con la CVRS, se construyeron ecuaciones de regresión lineal. Resultados: La población mostró puntuaciones de CVRS de 39,3 ±9,1 (componente físico) y 45,5 ±13,8 (componente mental). Ansiedad y depresión tuvieron correlación fuerte con el componente mental (r = -0,641 y r = -0,741 respectivamente), mientras que la PPS la tuvo con el componente físico (r = 0,617). El modelo de regresión lineal que mejor explicó la varianza del componente mental fue diseñado con las variables ansiedad y depresión combinadas (R= 77,3%; p< 0,001). Conclusiones: La fuerte influencia de la comorbilidad psiquiátrica en la CVRS de los pacientes con dolor neuropático oncológico hace necesario que el plan de atención integral de estos pacientes incluya intervenciones para su oportuno diagnóstico y tratamiento.
