HTA NHS R&D HTA ProgrammeT he research findings from the NHS R&D Health Technology Assessment (HTA) Programme directly influence key decision-making bodies such as the National Institute for Clinical Excellence (NICE) and the National Screening Committee (NSC) who rely on HTA outputs to help raise standards of care. HTA findings also help to improve the quality of the service in the NHS indirectly in that they form a key component of the 'National Knowledge Service' that is being developed to improve the evidence of clinical practice throughout the NHS.The HTA Programme was set up in 1993. Its role is to ensure that high-quality research information on the costs, effectiveness and broader impact of health technologies is produced in the most efficient way for those who use, manage and provide care in the NHS. 'Health technologies' are broadly defined to include all interventions used to promote health, prevent and treat disease, and improve rehabilitation and long-term care, rather than settings of care.The HTA programme commissions research only on topics where it has identified key gaps in the evidence needed by the NHS. Suggestions for topics are actively sought from people working in the NHS, the public...

“…However, proxy reports may be biased by personal beliefs regarding what constitutes QOL from the perspective of a person who is cognitively intact. Therefore, a scale based on direct observation of behavior and affect might have much to offer if it were sensitive to change [10].…”

Background: We report on the responsiveness of a previously validated quality-of-life scale, the Quality of Life in Late-Stage Dementia scale (QUALID), as an outcome measure in a clinical trial of two psychotropic medications. Methods: Secondary analyses were conducted comparing outcome measures used in a randomized double-blind trial of two antipsychotics (olanzapine and risperidone) for the treatment of dementia-related behavioral symptoms. The QUALID was completed for 31 of the patients in addition to several measures of behavior-related dementia symptoms including the Neuropsychiatric Inventory, the Withdrawn Behavior subscale of the Multidimensional Observation Scale for Elderly Subjects, the Mini-Mental State Examination, and the Clinical Global Impression. Measures of safety and adverse effects included the Simpson-Angus Scale and records of specific adverse events. Results: A significant positive relationship was found between QUALID score and improvement in behavioral symptoms, and a negative association was found with adverse medication effects. Conclusions: The QUALID was sensitive to both the treatment effects and the adverse effects of medication in this sample of patients.

“…Furthermore, the perceived difficulties of using everyday technology among people with cognitive impairment must be taken into consideration when evaluating function (Rosenberg et al, 2009). However, during the literature research no instrument was found to include all relevant ADL areas and existing instruments lacked validity and reliability (Sikkes et al, 2009, Demers et al, 2000.…”
