Oximetry-supported self-management for chronic obstructive pulmonary disease: mixed method feasibility pilot project.

BACKGROUND: Pulse oximetry could potentially contribute to self-monitoring. NHS Lothian's 'Light Touch' service provided COPD patients with a self-management plan based on symptoms and oximetry. The service was overseen (though not actively monitored) by respiratory-trained community teams who were contactable by a telephone helpline. We aimed to assess the feasibility, perceived utility and impact of the 'Light Touch' service. METHODS: A before-and-after assessment of St George's Respiratory Questionnaire (SGRQ), Hospital Anxiety and Depression Scale (HADS) and use of healthcare resources during the 6-month feasibility study compared to the previous corresponding 6-months. Paired semi-structured interviews with patients at baseline and 6-months, interviews with managers and a focus group of professionals explored perceptions of the service and self-management. Transcripts were coded, and analysed thematically. RESULTS: We recruited 51 participants (mean age 69.7 years (SD 8.4); 21 (46%) male). 46 participants completed quantitative follow up (2 died, 2 were unwell, 1 refused). SGRQ: 21 (46%) participants improved by 4 or more (the minimum important difference); 12 (26%) deteriorated by 4 or more. HADS: more participants had normal scores for anxiety (65%) and depression (80%) at 6-months than at baseline (51 and 64%). More emergency therapy was prescribed during the study period compared to the previous year. Only 18 participants (39%) contacted the Light Touch Helpline during the 6-month study. Twenty patients provided a total of 36 interviews, 8 clinicians contributed to a focus group and 6 managers were interviewed. Patients considered that the oximetry readings heightened awareness of their condition and gave them confidence to make self-management decisions. Healthcare professionals valued oximetry as a tool for teaching people self-management skills, but were concerned that patients rarely contacted the teams for help or advice during the study. CONCLUSIONS: 'Light Touch' shows promise as a low-cost strategy for empowering patients' self-management skills and reducing reliance on clinical supervision.

Pilot randomised controlled trial of Help4Mood, an embodied virtual agent-based system to support treatment of depression.

INTRODUCTION: Help4Mood is an interactive system with an embodied virtual agent (avatar) to assist in self-monitoring of patients receiving treatment for depression. Help4Mood supports self-report and biometric monitoring and includes elements of cognitive behavioural therapy. We aimed to evaluate system use and acceptability, to explore likely recruitment and retention rates in a clinical trial and to obtain an estimate of potential treatment response with a view to conducting a future randomised controlled trial (RCT). METHODS: We conducted a pilot RCT of Help4Mood in three centres, in Romania, Spain and Scotland, UK. Patients with diagnosed depression (major depressive disorder) and current mild/moderate depressive symptoms were randomised to use the system for four weeks in addition to treatment as usual (TAU) or to TAU alone. RESULTS: Twenty-seven individuals were randomised and follow-up data were obtained from 21 participants (12/13 Help4Mood, 9/14 TAU). Half of participants randomised to Help4Mood used it regularly (more than 10 times); none used it every day. Acceptability varied between users. Some valued the emotional responsiveness of the system, while others found it too repetitive. Intention to treat analysis showed a small difference in change of Beck Depression Inventory II (BDI-2) scores (Help4Mood -5.7 points, TAU -4.2). Post-hoc on-treatment analysis suggested that participants who used Help4Mood regularly experienced a median change in BDI-2 of -8 points. CONCLUSION: Help4Mood is acceptable to some patients receiving treatment for depression although none used it as regularly as intended. Changes in depression symptoms in individuals who used the system regularly reached potentially meaningful levels.
