TL;DR
A study of nearly 2,000 adults who had inpatient surgery found that higher daily step counts after surgery were associated with fewer complications, fewer 30-day readmissions and shorter hospital stays. The observational findings show an association, not proof that walking caused the better outcomes.
A study published online May 6, 2026, found that adults who took more steps each day after inpatient surgery had lower rates of complications and 30-day hospital readmission, as well as shorter hospital stays. The analysis covered nearly 2,000 patients, but because it was observational, it cannot establish that walking more caused the improved outcomes.
Researchers analyzed data from a large National Institutes of Health research program. The patients had undergone various types of inpatient surgery and wore step-counting devices for at least seven days before their procedures and for several weeks afterward, on average.
For every additional 1,000 daily steps above a patient’s average presurgery count, the researchers found a 17% lower chance of complications and a 15% lower likelihood of being readmitted to the hospital within 30 days. More walking after surgery was also associated with shorter hospital stays. The report does not give further details here about the types of complications or the length of stay difference.
The source article, written by Lynne Christensen of Harvard Health and distributed by Tribune Content Agency, describes the study as observational. That design can identify relationships in the data but cannot show whether increased walking itself produced the differences. Patients who recover more easily may also be more able to walk.
Step Counts and Recovery Outcomes
The findings add to evidence that mobility after surgery may be relevant to recovery. The source report says medical centers commonly encourage patients to begin walking as soon as it is safe, in part to help prevent problems such as lung complications, blood clots, weakness and longer hospital stays.
For patients and care teams, step counts may offer a practical way to track activity and identify when someone may need additional support. But the study does not establish a universal daily target, or show that patients should push through pain or increase activity without guidance. Safe timing and pace depend on the procedure and the individual patient.

Walking After Inpatient Surgery
Surgical recovery varies with the type of operation, a person’s overall health and any complications, according to the Harvard Health article. Early movement is already used in postoperative care when clinicians consider it safe; the study adds an analysis of device-recorded steps before and after surgery.
Unlike a trial that assigns patients to different walking levels, this research examined patterns in existing data. It compared postoperative activity with each patient’s own average presurgery step count. The reported percentages describe associations for each additional 1,000 daily steps above that baseline; they are not guarantees of an individual patient’s outcome.
“For every additional 1,000 steps patients made each day over their average presurgical step count, researchers found a 17% lower chance of complications and a 15% reduced likelihood of being readmitted to the hospital within 30 days.”

Limits of the Step Count Findings
The available report does not specify whether the researchers adjusted for every factor that could affect both walking and recovery, such as the patient’s condition or the severity of surgery. It also does not establish a minimum effective step count, the best time to increase activity, or whether the same association applies across different procedures and patient groups.
The results cannot show whether walking more reduced complications, or whether people who were recovering well were simply able to walk more. The report also does not provide the study’s detailed methods, patient demographics, or absolute event rates, so readers cannot determine the underlying number of complications or readmissions from the percentages alone.

Follow-up and Patient Guidance
The source material does not identify a planned follow-up study or a next research milestone. Further research, particularly studies designed to test activity guidance, would be needed to clarify whether increasing steps directly improves outcomes and what levels are appropriate for different patients.
For now, patients should ask their surgical team when and how to move more, taking account of their procedure and recovery. Wearable step counters can help track activity, according to the Harvard Health article, and may help care teams spot when additional support is needed. The study does not replace individual medical advice.

Key Questions
What did the study find?
In an analysis of nearly 2,000 adults after inpatient surgery, each additional 1,000 daily steps above a patient’s presurgery average was associated with a 17% lower chance of complications and a 15% lower likelihood of readmission within 30 days. More steps were also linked to shorter hospital stays.
Does the study prove walking prevents complications?
No. It was observational, so it found associations but cannot prove that walking more caused fewer complications or readmissions.
How soon should patients walk after surgery?
The report does not set a universal schedule. It advises patients to ask their surgical team when it is safe to start increasing activity.
Does the study recommend a daily step target?
No specific target is reported. The analysis compared patients’ postoperative activity with their own average presurgery step count; it does not establish a recommended number of steps for recovery.
