Design outcomes

Primary

MeasureTime frame
Total ulcer free time with limbs intact over 18 months as measured in days using patient records

Secondary

MeasureTime frame
1. Clinical outcomes (these will be collected from clinical notes over the 18-month follow-up): 1.1. Whether the patient remained ulcer-free 1.2. Time to re-ulceration (measured in days) 1.3. Total number of ulcers 1.4. Proportion of patients deceased 1.5. Time to death 1.6. Whether patient had major amputation 1.7. Time to major amputation operation 1.8. Whether patient had minor amputation operation 1.9. Time to minor amputation 1.10. Days in hospital related to foot ulcer disease 1.11. Days in hospital not related to foot ulcer disease 2. Psychological/behavioural risk factors targeted in REDUCE to examine mechanisms at Baseline, 6 weeks, 3 months, 6 months & 18 months post-randomisation. 2.1. Brief Illness Perception Questionnaire (B-IPQ): Examines the participant’s perception of their illness 2.2. Cognitive and Behavioural Responses Questionnaire (CBRQ) – short version: Examines participant’s beliefs about their symptoms 2.3. Patient Health Questionnaire-9 (PHQ-9): Assesses depression 2.4. International Physical Activity Questionnaire - Elderly (IPAQ-E) – short form: Assesses participant physical activity 2.5. Nottingham Assessment of Functional Footcare (NAFF): Examines foot self-care behaviours 2.6. Scale of Positive And Negative Experience (SPANE-P) - positive items only: Examines positive feelings 2.7. Social Provisions Scale (SPS): Examines social relationships and support 3. Economic outcomes to examine cost-effectiveness at Baseline, 6 months and 18 months post-randomisation. 3.1. ICEpop CAPability measure for Adults (ICECAP-A): Measures capability in adults including attachment, stability, achievement, enjoyment and autonomy 3.2. EQ5D-5L consisting of the EQ5D descriptive system and the EQ Visual Analogue Scale (EQ VAS): Measures mobility, self-care, usual activities, pain/discomfort and anxiety/depression
