Study characteristics
Methods	Design: RCT Baseline time point (T1): hospital admission Outcome time point (T2): 7 days after T1
Participants	Inclusion criteria: aged ≥ 70 years; admitted to the medical wards; unable to walk by themselves, or displayed inhibition going for a walk by themselves; a provisional diagnoses including heart‐, lung‐ and diabetes‐related morbidities Exclusion criteria: unable to understand plain English statement and consent form; people with a stroke and undergoing rehabilitation with the physiotherapist; significant dementia precluding the possibility of gathering reliable exercise self‐efficacy data Exercise arm n at baseline: 27 Age mean: 84.00 (SD 6.19) years Barthel Index (0–100) on admission: 59.15 Control arm n at baseline: 28 Age mean: 82.54 (SD 7.45) years Barthel Index (0–100) on admission: 58.07
Interventions	Exercise arm TIDieR item 1: (brief name: provide the name or a phrase that describes the intervention): supervised or assisted walking. TIDieR item 2: (why: describe any rationale, theory or goal of the elements essential to the intervention): due to benefits observed in walking programmes in other settings the authors aimed to test whether similar benefits are observed in functional independence and exercise self‐efficacy in older hospitalised people. TIDieR item 3: (what (materials): describe any physical or informational materials used in the intervention, including those provided to participants or used in intervention delivery or in training of intervention providers): walking aids as required. TIDieR item 4: (what (procedures): describe each of the procedures, activities or processes (or a combination) used in the intervention, including any enabling or support activities): participants were supervised or assisted by nursing staff to go for a walk twice per day. Participants were provided with a chair to rest midway through their walk. TIDieR item 5: (who provided: for each category of intervention provider (e.g. psychologist, nursing assistant), describe their expertise, background and any specific training given): the nursing staff in the units were encouraged to attend a short education session that covered the intent of the research and the way in which the walking programme was to be implemented. They were instructed that the general intent was to encourage and enable a longer walk on each occasion. TIDieR item 6: (how: describe the modes of delivery (such as face‐to‐face or by some other mechanism, such as Internet or telephone) of the intervention and whether it was provided individually or in a group): face‐to‐face, individually. TIDieR item 7: (where: describe the type(s) of location(s) where the intervention occurred, including any necessary infrastructure or relevant features): 3 medical units. TIDieR item 8: (when and how much: describe the number of times the intervention was delivered and over what period of time including the number of sessions, their schedule, and their duration, intensity or dose): twice per day, 7 days per week. The distance walked twice per day was the maximum distance able to be comfortably walked as decided by that individual at that time. TIDieR item 9: (tailoring: if the intervention was planned to be personalised, titrated or adapted, then describe what, why, when and how): the distance walked twice per day was the maximum distance able to be comfortably walked as decided by that individual at that time. Jirovec's (1991) technique was followed in determining their comfortable limit. TIDieR item 10: (modifications: if the intervention was modified during the course of the study, describe the changes (what, why, when and how)): not specified. TIDieR item 11: (how well (planned): if intervention adherence or fidelity was assessed, describe how and by whom, and if any strategies were used to maintain or improve fidelity, describe them): the supervising staff member was asked to document the walk and the approximate distance. TIDieR item 12: (how well (actual): if intervention adherence or fidelity was assessed, describe the extent to which the intervention was delivered as planned): not specified other than 2 participants were excluded from analyses as they completed < 70% of their walks. Control arm TIDieR item 1: usual care. TIDieR item 2: not specified. TIDieR item 3: not specified. TIDieR item 4: the participants received normal levels of nursing care and assistance during their hospitalisation. They were encouraged to be 'normally ambulant'. Many, if not most of the sample had 1 or 2 visits from a physiotherapist. TIDieR item 5: not specified. TIDieR item 6: not specified. TIDieR item 7: 3 medical units. TIDieR item 8: not specified. TIDieR item 9: not specified. TIDieR item 10: not specified. TIDieR item 11: not specified. TIDieR item 12: not specified.
Outcomes	Barthel Index at T2 Falls during hospitalisation Mortality during hospitalisation Maximum distance able to walk at T2
Notes	Excluded participants discharged before day 7 of hospitalisation (9 participants in intervention group vs 7 participants in control group), and those who completed < 70% of the intervention (2 participants).
