A comparison of remote therapy, face to face therapy and an attention control intervention for people with aphasia: a quasi-randomised controlled feasibility study.

OBJECTIVE: To test the feasibility of a randomised controlled trial comparing face to face and remotely delivered word finding therapy for people with aphasia. DESIGN: A quasi-randomised controlled feasibility study comparing remote therapy delivered from a University lab, remote therapy delivered from a clinical site, face to face therapy and an attention control condition. SETTING: A University lab and NHS outpatient service. PARTICIPANTS: Twenty-one people with aphasia following left hemisphere stroke. INTERVENTIONS: Eight sessions of word finding therapy, delivered either face to face or remotely, were compared to an attention control condition comprising eight sessions of remotely delivered supported conversation. The remote conditions used mainstream video conferencing technology. OUTCOME MEASURES: Feasibility was assessed by recruitment and attrition rates, participant observations and interviews, and treatment fidelity checking. Effects of therapy on word retrieval were assessed by tests of picture naming and naming in conversation. RESULTS: Twenty-one participants were recruited over 17 months, with one lost at baseline. Compliance and satisfaction with the intervention was good. Treatment fidelity was high for both remote and face to face delivery (1251/1421 therapist behaviours were compliant with the protocol). Participants who received therapy improved on picture naming significantly more than controls (mean numerical gains: 20.2 (remote from University); 41 (remote from clinical site); 30.8 (face to face); 5.8 (attention control); P <.001). There were no significant differences between groups in the assessment of conversation. CONCLUSIONS: Word finding therapy can be delivered via mainstream internet video conferencing. Therapy improved picture naming, but not naming in conversation.

The challenging nature of patient identifiers: an ethnographic study of patient identification at a London walk-in centre.

The correct identification of a patient's health record is the foundation of any safe patient record system. There is no building of a ;patient history', no sharing or integration of a patient's data without the retrieval and matching of existing records. Yet there can often be errors in this process and these may remain invisible until a safety incident occurs. This article presents the findings of an ethnographic study of patient identification at a walk-in centre in the UK. We offer a view of patient identifiers as used in practice and show how seemingly simple data, such as a person's name or date of birth, are more complex than they may at first appear and how they potentially pose problems for the use of integrated health records. We further report and discuss a dichotomy between the identifiers needed to access health records and the identifiers used by practitioners in their everyday work.

Evaluating the Benefits of Aphasia Intervention Delivered in Virtual Reality: Results of a Quasi-Randomised Study.

INTRODUCTION: This study evaluated an intervention for people with aphasia delivered in a novel virtual reality platform called EVA Park. EVA Park contains a number of functional and fantastic locations and allows for interactive communication between multiple users. Twenty people with aphasia had 5 weeks' intervention, during which they received daily language stimulation sessions in EVA Park from a support worker. The study employed a quasi randomised design, which compared a group that received immediate intervention with a waitlist control group. Outcome measures explored the effects of intervention on communication and language skills, communicative confidence and feelings of social isolation. Compliance with the intervention was also explored through attrition and usage data. RESULTS: There was excellent compliance with the intervention, with no participants lost to follow up and most (18/20) receiving at least 88% of the intended treatment dose. Intervention brought about significant gains on a measure of functional communication. Gains were achieved by both groups of participants, once intervention was received, and were well maintained. Changes on the measures of communicative confidence and feelings of social isolation were not achieved. Results are discussed with reference to previous aphasia therapy findings.

A pragmatics' view of patient identification.

BACKGROUND: Patient identification is a central safety critical aspect of healthcare work. Most healthcare activities require identification of patients by healthcare staff, often in connection with the use of patient records. Indeed, the increasing reliance on electronic systems makes the correct matching of patients with their records a keystone for patient safety. Most research on patient identification has been carried out in hospital settings. The aim was to investigate the process of identification of patients and their records in the context of a primary healthcare clinic. METHOD: A qualitative field study was carried out at a Walk-In Centre in London (UK). RESULTS: The identification of patients and their records was found to be a context-dependent process, both when formalised in procedures and when relying on informal practices. The authors discovered a range of formal and informal patient identifiers were used in this setting, depending on the task at hand. The theoretical lens of Pragmatics was applied to offer an explanation of this identification process. CONCLUSIONS: Context provides the cognitive scaffolding for a process of 'suitably constrained guesswork' about the identity of patients and their records. Implications for practice and for system design are discussed. Practitioners and technology designers should be aware of the risk for misidentifications inherent in this natural information processing activity.

A method for determining information flow breakdown in clinical systems.

This paper presents Determining Information flow Breakdown (DIB), a method for analyzing adverse events in clinical environments from the perspective of breakdowns in information flow. The larger context for DIB is that it is the first stage in a process that promotes organizational learning in response to adverse events through the design of novel IT solutions. DIB is based on the theoretical view of distributed cognition and adopts a system-wide view of failures. DIB is both a reactive and a proactive method in that it aims to locate the causes of either actual or potential adverse events by investigating all elements of the system related to a chosen aspect of patient care. It was developed and evolved using a case study approach whereby data on actual and potential adverse events in clinical environments was collected, modeled and analyzed using successive versions of the method. We provide an explanation and overview of the DIB method, and discuss our experiences of applying it in practice via a detailed example.
