Error reduction therapy in reducing struggle and grope behaviours in apraxia of speech.

We report an intervention study focused on the speech production difficulties present in acquired apraxia of speech (AOS). The intervention was a self-administered computer therapy that targeted whole word production and incorporated error reduction strategies. The effectiveness of the therapy was contrasted to that of a visuospatial sham computer program, and performance across treated words, and two sets of matched words, was assessed. Two groups of participants completed the study which employed a two-phase cross-over treatment design. Participants were randomly assigned to a speech first or sham first condition. Treatments were administered for six weeks, with a four week rest between interventions. Participants were assessed five times in total; twice at baseline, once following each of the intervention phases, and once following a lapse of eight weeks after the end of the second phase of intervention. The occurrence of accurate word production and speech characterised by struggle and groping behaviours was recorded on a repetition task. Participants showed significant gains in speech accuracy and fluency, and reductions in articulatory groping and struggle behaviours following the use of the speech program. These gains were largely maintained once the therapy was withdrawn.

Appropriateness of hospital utilization. The validity and reliability of the Intensity-Severity-Discharge Review System in a United Kingdom acute hospital setting.

Assessing the appropriateness of hospital utilization in the United Kingdom may yield practical solutions to problems faced by both purchasers and providers of health care in the National Health Service. It is, however, essential that such assessment is based on a method that is both valid and reliable--in particular, valid in the context in which it is applied. Whereas American methods for the assessment of appropriateness have been shown to be valid in the United States, it is pertinent to question whether the application of such methods to the National Health Service also is valid given the different circumstances, both cultural and financial, under which health care is provided. A study of the appropriateness of admission and hospital stay for a sample of admissions to a large acute hospital in the United Kingdom was carried out, and the assessment of appropriateness was made using the Intensity-Severity-Discharge Review System with Adult criteria (ISD-A). The validity and reliability of using the ISD-A for assessing hospital utilization in the United Kingdom was evaluated. The ISD-A was found to have high reliability and to be valid for assessing appropriateness in the United Kingdom when a full range of alternative forms of care are presumed to be available. It was not found to be valid currently, therefore, for routine assessment of hospital utilization within the National Health Service, when alternatives often are not available.
