The King's Brief Interstitial Lung Disease (KBILD) questionnaire: an updated minimal clinically important difference.

Introduction: The King's Brief Interstitial Lung Disease (KBILD) is a 15-item validated health-related quality of life (HRQOL) questionnaire. The method of scoring the KBILD has recently changed to incorporate a logit-scale transformation from one that used raw item responses, as this is potentially a more linear scale. The aim of this study was to re-evaluate the KBILD minimal clinically important difference (MCID) using the new logit -transformed scoring.

Interventions to improve symptoms and quality of life of patients with fibrotic interstitial lung disease: a systematic review of the literature.

Background: Patients with fibrotic interstitial lung disease have symptom control and quality of life (QoL) needs. This review aims to evaluate the evidence for the use of interventions in improving dyspnoea, other symptoms and QoL.

Methods: Eleven databases, relevant websites and key journals were hand-searched.

The development and validation of the King's Sarcoidosis Questionnaire for the assessment of health status.

Rationale: Health status is impaired in patients with sarcoidosis. There is a paucity of tools that assess health status in sarcoidosis. The objective of this study was to develop and validate the King's Sarcoidosis Questionnaire (KSQ), a new modular health status measure.
