Ambulation following surgery has been found to be beneficial for patients; however, nurses and doctors struggle with getting post-operative, hospitalized patients to walk on their own. One promising strategy to address this might be an ambulation orderly, an employee whose single responsibility is to assure that patients walk 3-4 times per day. However, the effect of the ambulation orderly on post-operative physical activity has not yet been described. It is important to quantify what the ambulation orderly does in order to assess if this is an effective method for helping patients walk. As a result, the investigators will perform a pilot randomized controlled trial to test the effects of an ambulation orderly in patients hospitalized with recent cardiac surgery. Half of the patients will be assigned to walk with the ambulation orderly 3-4 times/day and the control group will be given standard nursing encouragement and assistance and encouragement to walk. The investigators will evaluate the average total daily step counts (over the hospital course, usually 4-7 days) and the change in walking distance between a baseline and a final 6 minute walk test. The investigators will also evaluate exercise physiologic parameters (heart rate, oxygen saturation) during ambulation, patient functional independence, and patient satisfaction.
The investigators will perform a prospective randomized controlled trial at Baystate Medical Center, a 684-bed academic teaching hospital that serves as the referral center for a population of approximately 800,000 people living in Western Massachusetts.
The responsibility of the ambulation orderly is to walk patients after having a cardiac surgery, such as a coronary artery bypass surgery or a valve replacement or repair. Patients will be randomized to receive visits from the ambulation orderly (ambulation group) or to receive the standard care of Baystate Medical Center (control group). The standard of care will be nurse-directed ambulation, as is currently done in all other nursing floors at Baystate Medical Center. Nurses will be instructed to walk with the patients as they did before the initiation of the ambulation orderly and as they do when the orderly is on vacation, at conferences, training, or away for illness.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Ambulation Orderly Intervention | Experimental | Patients that are in this group are those randomized to receive visits from the ambulation orderly (ambulation group). The patients in this group will receive the visits from the ambulation orderly in addition to the standard of care that occurs with the rest of the hospital and with the control group. |
|
| Control Group | No Intervention | This is for the patients who are randomized to receive the standard care of Baystate Medical Center. The standard of care will be nurse-directed ambulation, as is currently done in all other nursing floors at Baystate Medical Center. Nurses will be instructed to walk with the patients as they did before the initiation of the ambulation orderly and as they do when the orderly is on vacation, at conferences, training, or away for illness. These patients will not receive visits from the ambulation orderly. |

| Ambulation orderly | Procedure | The responsibility of the ambulation orderly is to walk patients after having a cardiac surgery, such as a coronary artery bypass surgery or a valve surgery. Baystate Medical Center hired an ambulation orderly May 8, 2013. The ambulation orderly is generally a high school graduate with some training in safe lifting and exercise, but extensive training is not required. In general, the goal is to have 1 ambulation orderly present 7 days a week for 8 hr per day. When available, ambulation orderlies are responsible for walking the patients who have been cleared by the clinical exercise physiologist or nurse up to 4 times per day. The walking of the patients occurs through the halls of the 6th floor of the Mass Mutual wing of Baystate Medical Center. |
| Measure | Description | Time Frame |
|---|---|---|
| Average Daily Step Counts while on M6 (cardiac surgery general floor.) | The patient will wear an accelerometer, which will keep track of the amount of steps the patient took each day over the course of the hospitalization. | From arrival on M6 to hospital discharge. This is typically from post operative day 3 until post operative day 9-12. |
| Average change in walking distance between baseline and final 6-minute walk | Each patient will complete a 6 minute walk after arriving on M6 (from intensive care until) and again at hospital discharge. The difference in distance walked will be compared. | From arrival on M6 (baseline) to hospital discharge (final). This is typically from post operative day 3 until post operative day 9-12 |
| Measure | Description | Time Frame |
|---|---|---|
| Average Slope of Progression in Average Total Daily Step Counts | The patient will wear an accelerometer, which will keep track of the amount of steps the patient took each day. The progression between groups will be compared. | From arrival on M6 to hospital discharge. This is typically from post operative day 3 until post operative day 9-12. |

| Average Daily Step Count on the 3rd day after arrival on M6 | The step counts on the 3rd day after arrival on M6 will be compared in all groups. All patients are expected to still be in the hospital at this time. | 3rd day on M6 as part of study (typically post operative day 6 or 7) |
| Average Total Daily Energy Expenditure | The patient will wear an accelerometer, which will keep track of the total daily expenditure in calories per day. | From arrival on M6 to hospital discharge. This is typically from post operative day 3 until post operative day 9-12. |
