Abstract
Cíle: Tato studie měla za cíl zjištění diagnostické přesnosti české verze souboru tří otázek ke stanovení diagnózy syndromu neklidných nohou (Restless Legs Syndrome, RLS), které se používají v epidemiologických studiích prováděných dotazníkovou cestou bez asistence investigátora. Originální anglická verze dotazníku byla publikována v roce 2003 Mezinárodní skupinou pro výzkum RLS (International RLS study group) společně s hlavními a vedlejšími diagnostickými kritérii pro klinické nebo telefonické stanovení diagnózy RLS. Soubor a metody: Sada otázek byla přeložena do češtiny a pak zaslepeně zpět do angličtiny, aby nedošlo k posunu významu. Ženy přicházející ke kontrole na Gynekologickou kliniku 1. LF UK a VFN v Praze v 34.–38. týdnu těhotenství byly požádány o vyplnění výše zmíněného dotazníku. Následně lékař vycvičený v diagnostice RLS pacientky kontaktoval na jimi zadaném telefonním čísle k standardnímu diagnostickému rozhovoru k ověření či vyloučení diagnózy RLS. Výsledky obou metod byly porovnávány a byla stanovena senzitivita, specificita, pozitivní a negativní prediktivní hodnoty. Výsledky: Dotazníkovou studii podstoupilo celkem 776 těhotných žen, ve věku 18–49 let. Celkem bylo validováno 199 dotazníků, u 65 osobní pohovor potvrdil diagnózu RLS. Pozitivita všech tří otázek má 89% specificitu, ale jen přibližně 78% pozitivní prediktivní hodnotu a senzitivitu. Za použití pouze první otázky je senzitivita 94 % a negativní prediktivní hodnota 96 %. Ze všech vyšetřených žen na všechny tři otázky odpovědělo pozitivně 28,0 % (95% konfidenční interval je 24,9–31,2 %). Závěr: Studie validovala českou verzi otázek a prokázala jejich relativně vysokou diagnostickou přesnost.
Aims: The aim of this study was to estimate diagnostic accuracy of the Czech version of a self-administered minimum question set to diagnose the Restless Legs Syndrome (RLS). The wording of the three questions was published in 2003 by the International RLS study group together with the diagnostic criteria. Material and methods: The question set was translated into Czech, followed by blind translation back to English. Women in 36th–38th week of pregnancy were asked to complete the questionnaire. Subsequently, the women were contacted over a telephone by a physician trained in diagnosing RLS and a standard telephone interview to establish or exclude the diagnosis of RLS was performed. The results of both methods were compared to estimate sensitivity, specificity, positive and negative predictive values of the minimum question set. Results: We surveyed 776 pregnant women (18–49 years old) who came to a prenatal outpatient clinic to consult an obstetrician at the third trimester (36th–38th week of pregnancy). In total, 199 questionnaires were validated; personal interview confirmed the diagnosis of RLS in 65 of them. Positive response to all three questions yields specificity of 89% but only about 78% sensitivity and positive predictive value. Positive response to the first question only has sensitivity of 94% and negative predictive value of 96%. The prevalence of RLS during pregnancy estimated using the three-question questionnaire was 28% (95% confidence interval from 24.9 to 31.2%). Conclusion: Our study validated the Czech version of the minimal question set for diagnosing RLS and confirmed its high diagnostic accuracy.
