Validation of St. George's Respiratory Questionnaire (SGRQ) in Chronic Obstructive Pulmonary Disease (COPD) at Respira Lung Hospital Yogyakarta

Abstract

ABSTRAKPrevalensi Penyakit Paru Obstruktif Kronis (PPOK) di Indonesia semakin meningkat. Diperkirakan pada tahun 2020 PPOK akan menjadi penyebab kematian ketiga di dunia. Salah satu tujuan terapi dari PPOK sebagai penyakit kronik adalah meningkatkan kualitas hidup pasien. Penelitian ini bertujuan untuk memvalidasi kuesioner St. George's Respiratory Questionnaire (SGRQ) versi Indonesia sebagai instrumen untuk mengukur kualitas hidup pasien PPOK di RS Paru Respira, Yogyakarta. Penelitian ini menggunakan rancangan potong lintang yang dilakukan di RS Paru Respira, Yogyakarta dari bulan Juni-Juli 2016. Pengumpulan data dilakukan dengan menggunakan rekam medik pasien dan wawancara secara langsung kepada pasien menggunakan kuesioner SGRQ. Subyek penelitian yang digunakan adalah pasien PPOK yang berusia 17-80 tahun. Analisis statistik dilakukan untuk mengetahui validitas konstruk, known-group dan reliabilitas kuesioner. Sejumlah 41 responden berpartisipasi dalam penelitian ini. Kuesioner SgRQ versi Indonesia memenuhi kriteria reliabilitas dengan nilai Cronbach alpha mencapai > 0.7 untuk domain gejala, aktivitas dan dampak. Terdapat 17 pertanyaan dan 10 pertanyaan pada ketiga domain yang tidak memenuhi validitas konvergen dan diskriminan. Perbedaan bermakna muncul pada domain gejala berdasar kelompok umur 17-48 dan 49-80 tahun (p<.05). Kuesioner The SGRQ versi Indonesia belum memenuhi kriteria validitas namun masih memenuhi kriteria reliabel. Kata kunci: SGRQ, Indonesia, PPOK, validitas ABSTRACTThe prevalence of COPD in Indonesia is getting increase. Over the world, COPD is predicted to be the third cause of death in 2020. As the chronic disease, quality of life became one of the outcome treatments of COPD. This research was aimed to validate Indonesian version of St. George's Respiratory Questionnaire (SGRQ) Indonesian. This study used cross sectional design approach from June to July 2016, conducted in Respira Lung Hospital, Yogyakarta. Data was collected from medical record and direct interviews to patients using SGRQ. An inclusion criterion was adult patients with COPD. Some statistical tests were performed to analyze construct validity, known group validity and reliability of Indonesian version of SGRQ. We recruited 41 respondents. The SGRQ meet reliability criteria with the value of Cronbach alpha are > 0.7 for symptom, activity and impact domains. There are 17 questions and 10 questions in symptom, activity and impact domains which do not meet convergent and discriminant validity. The significant difference is found in symptom domain for the 17-48 and 49-80 year age. The SGRQ Indonesian version is not valid enough to be used in clinical practice but still reliable.

The Effect of Treatment during A Haze/Post-Haze Year on Subsequent Respiratory Morbidity Status among Successful Treatment Tuberculosis Cases

“…In our study, the overall SGRQ domain score in both groups was still higher (worse morbidity) than that of healthy subjects without a history of respiratory disease [9]. Our findings are consistent with previous studies, indicating that physical (symptom and activity domain) and psycho-social (impact domain) scores after successful treatment of respiratory diseases show a poorer score than in the general population [4,30,32,33].…”

“…There is no routine information available in Indonesia about respiratory morbidity assessment in TB treatment process [4,5]. In this study, we assessed the respiratory morbidity using St Georges Respiratory Questionnaires (SGRQ), which is a validated measurement tool for HRQoL for several chronic respiratory diseases [9,27], including in TB studies in the USA [30] and in Indonesia [31].…”

“…Both respiratory morbidity aspects are covered in Health-related Quality of Life (HRQoL) [2,3]. Despite successful TB treatment bringing significant benefit to patients in terms of relief from physical symptoms [4,5,6], their quality of life compared with the general population is still poor [6,7]. Several factors are already known to be associated with the quality of life of TB patients, including demographic (age, gender), socioeconomic (income, education, social security), behavior (smoking), therapy related (treatment adherence), and psycho-social aspects (stigmatization) [8,9,10].…”

Antibacterial activity of gel hand sanitizer from seaweed extract (Kappaphycus alvarezii)

“…The inhibition zone test was carried out using the disk diffusion method to determine the clear zone created from seaweed extract (K. alvarezii). The diffusion method is the process of measuring and observing the diameter of the clear zone formed in the disc area, the measurement process is carried out after being left for 18-24 hours and then measured using a caliper [27].…”

Identifikasi Fungsi Status Respirasi Pada Pekerja Pabrik Akibat Dampak Dari Limbah Pabrik Kertas

“…Setiap respon kuesioner mempunyai bobot nilai yang berbeda mulai dari 0 dan tertinggi 100. Setiap komponen dari kuesioner dinilai dalam 3 tahap yaitu : bobot item yang tertinggal diurangi dari bobot maksimum untuk tiap komponen, bobot semua item yang tertinggal dikurangi dari bobot maksimum dari total score dan skor dikalkulasi dengan membagi jumlah bobot dengan bobot maksimum dalam komponen dan didapatkan hasil sebagai presentase : Score = 100 x Jumlah Bobot dari Item positif dalam komponen Jumlah bobot semua item dalam komponen Total score dihitung dengan cara yang sama : Score = 100 x Jumlah Bobot dari Item positif dalam komponen Jumlah bobot semua item dalam kuesioner Jumlah bobot maksimum untuk setiap komponen dan totalnya adalah: Gejala : 662,5; Aktivitas: 1209,1; Dampak : 2117,8; Total: 3989,4. di mana nilai dari skor total yang tinggi menunjukkan kualitas hidup pasien yang buruk (Jones, 2003 ;Pratiwi & Perwitasari, 2017). Instrumen SGRQ telah dilakukan uji validitas dan reliabilitas, b).…”
