Calidad de vida relacionada con la salud en personas chilenas con enfermedad pulmonar obstructiva crónica

Resumen

Background: Chronic obstructive pulmonary disease (COPD) has a relevant impact on health-related quality of life (HRQoL). Short Form 6 dimensions (SF-6D) quality of life tool allows researchers to calculate preference-based utilities using data from SF-12 or SF-36 questionnaires. Aim: To provide normative values of SF-6D derived from SF-12 for Chilean patients with COPD. Material and methods: SF-6D utility index was calculated using data from the 2009/2010 Chilean National Health Survey. Sixty nine male and 120 female patients with COPD participated in the survey. Data was stratified by gender, age, region, marital status, smoking status, monthly incomes, educational level and area. Results: The mean (± standard deviation) SF-6D utility index for Chilean patients with COPD was 0.65 ±0.15. The scores for men and women were 0.68 ±0.15 and 0.64 ±0.15, respectively. Patients with high incomes and educational level reported higher SF-6D scores. Ceiling effect was not a limitation when SF-6D was used in these Chilean patients. Conclusions: The current study provides normative values of SF-6D derived from SF-12 for Chilean patients with COPD.
