Clinical and Cost Effectiveness of Alpha-Stim AID CES
Study Details
Study Description
Brief Summary
This is a single-centre research study in patients seen within an NHS Improving Access to Psychological Interventions (IAPT) service with suspected generalised anxiety disorder (GAD). The study will involve 120 patients from the Leicestershire and Rutland area in England, United Kingdom.
Participants will use the Alpha-Stim AID Cranial Electrotherapy Stimulations (CES) medical device, which is approved for use and proven to be safe and work for the treatment for anxiety, depression and insomnia.
Participants will use the Alpha-Stim AID for 60 minutes every day for 6 or 12 weeks, either whilst on the waiting list for standard care treatment from IAPT, or in conjunction with standard care treatment from IAPT.
The study will involve 6 study visits - one face-to-face at visit 1, followed by 5 visits via telephone at week 4, 6, 8, 12 and 24. At each visit, participants will be asked to complete questionnaires to assess anxiety, depression, sleep difficulty, quality of life and work and social functioning.
The purpose of the study is to gather evidence for the clinical benefits and cost effectiveness of the Alpha-Stim AID when used in an NHS setting - how well does it work, and does it's use result in cost savings for the NHS.
The study may show that the Alpha-Stim AID should be available on the NHS for patients with suspected GAD.

Detailed Description
Participants will have a baseline visit (day 1, visit 1) following identification as potentially eligible. The baseline visit will be face-to-face with a member of the research team, held at routine facilities used by the IAPT service. At the baseline visit, the participant will be consented for participation, have a urine pregnancy test first (if a female of child bearing potential) and the research team will administer the GAD-7 secondly, followed by EQ-5D-5L, WASA, PHQ-9, Athens, and CSRI surveys. Participants will then be instructed on how to use the Alpha-Stim AID device, and will have their first 60 minute, self-directed treatment session at home.
All further visits will be facilitated via telephone, scheduled between the research team and participant, within a 5 calendar day window of each time point.
At visit 2 (week 4), visit 3 (week 6), visit 4 (week 8), visit 5 (week 12) and visit 6 (week 24), the research team will administer the GAD-7, EQ-5D-5L, WASA, PHQ-9 and Athens. The CSRI will be repeated only at visit 5 and 6. Compliance with the 60 minute daily treatment session will also be assessed during the 6 or 12 week treatment window, in addition to any adverse events.
The 60-minute self-directed Alpha-Stim AID treatment sessions are undertaken at participant's home, on a daily basis for 6 weeks for all participants. During this 6-week period, participants will be on the waiting list for high intensity psychological therapy interventions.
Following 6 weeks of Alpha-Stim AID CES treatment, participants have the option to receive a further 6 weeks of treatment, which is likely to coincide with start of high intensity psychological therapy interventions as clinically indicated.
Following a maximum of 12 weeks' treatment with Alpha-Stim AID CES, all participants will cease to receive treatment on study.
All participants will continue to receive standard care assessment, as undertaken by the NHS IAPT service, standard care high intensity psychological therapy interventions as clinically indicated and provided by the NHS IAPT service, and standard care pharmacological treatments as prescribed by the participant's GP. Participation in this study will not influence nor compromise standard care treatment - all study procedures are additional to standard care. Participation in the study will have no impact upon the duration of the waiting time for high intensity psychological therapy interventions.

Outcome Measures
Primary Outcome Measures
- Clinical Effectiveness in Generalised Anxiety Disorder Measured by at Least a 5 Point Reduction in Scores on the GAD-7 [24 weeks]
The primary objective of this study is to evaluate the clinical effectiveness of treatment with Alpha-Stim AID Cranial Electrotherapy Stimulations (CES) for participants with a primary working diagnosis of generalised anxiety disorder (GAD), as defined by the NHS IAPT service in terms of reliable improvement (at least a 5 point improvement on the GAD-7),or recovery (total score of less than 7 and at least a 5 point improvement on the GAD-7), from baseline to week 24, following previous treatment with low intensity psychological therapy intervention.
Secondary Outcome Measures
- Cost Effectiveness in Generalised Anxiety Disorder Compared to Current Treatment Approaches [24 weeks]
The secondary objective of this study is to evaluate the cost effectiveness of treatment with Alpha-Stim AID Cranial Electrotherapy Stimulations (CES) for participants with a primary working diagnosis of generalised anxiety disorder (GAD), in terms of health and social care service cost, and patient cost, from baseline to week 24, following previous treatment with low intensity psychological therapy intervention. The health and social care service cost and patient cost will be aggregated to determine the QALY (quality adjusted life year) value of the intervention. QALYs are used by the National Institute for Clinical Excellence (NICE) in the United Kingdom to determine the cost effectiveness of a treatment, and to determine whether it should be made available free at point of use in the National Health Service (NHS).
- Clinical Effectiveness in Depression as Measured by Reduction of at Least 6 Points in Scores on the Personal Health Questionnaire (PHQ-9) [24 weeks]
The third objective of this study is to evaluate the clinical effectiveness of treatment with Alpha-Stim AID Cranial Electrotherapy Stimulations (CES) for depression in participants with a primary working diagnosis of generalised anxiety disorder (GAD), in terms of reliable improvement (a 6 point reduction in scores on the PHQ-9) or recovery (a score of 9 or less and at least a 6 point drop on the PHQ-9), from baseline to week 24, following previous treatment with low intensity psychological therapy intervention.
- Clinical Effectiveness in Insomnia as Measured by at Least a 50% Reduction in Score on the Athens Insomnia Scale (AIS) [24 weeks]
The fourth objective of the tertiary objective of this study is to evaluate the clinical effectiveness of treatment with Alpha-Stim AID Cranial Electrotherapy Stimulations (CES) for insomnia in participants with a primary working diagnosis of generalised anxiety disorder (GAD), in terms of reliable improvement (at least a 50% reduction in scores on the AIS), and recovery (a score of less than 4 and a reduction of at least 50% in AIS score), from baseline to week 24, following previous treatment with low intensity psychological therapy intervention.
