TL;DR
For some questionnaires, it is known that the smallest change in score that patients consider important is 0.5 per question, and even if the mean difference between a treatment and a control is appreciably less than the smallest changes that is important, treatment may have an important impact on many patients.

The Paediatric Asthma Quality of Life Questionnaire has good measurement properties and is valid both as an evaluative and a discriminative instrument and captures aspects of asthma most important to the patient and adds additional information to conventional clinical outcomes.

The Paediatric Asthma Caregiver's Quality of Life Questionnaire functions well as both an evaluative and a discriminative instrument and showed acceptable levels of longitudinal and cross-sectional correlations with the child's asthma status and health-related quality of life and with other measures of caregiver health- relatedquality of life.

The 4-hour desensitization protocol may not be suitable for all patients allergic to CP, whereas a modified prolonged protocol seems to be more tolerable, and the short protocol may be at tempted initially but should be replaced by the prolonged protocol if adverse effects appear.

The arguments in favor of the scorecard approach from the clinical medicine viewpoint are that the process of measuring outcome provides a formal approach to improving individual decision making and system-wide allocation of resources, as shown in other complex work environments with the adoption of the Deming method of continuous quality improvement.

Managing the Quality of Care

Quality assurance in health care is about making sure that the service is being provided to a level that has been defined according to pre-determined criteria and standards, but many standards do not exist and if they do they are frequently written in ways that make them very difficult to measure.
