2 days shorter hospital stay
The opioid-sparing effect tracked with a roughly two-day shorter median stay after bypass.
The finding
Alongside the morphine reduction, the cardiac work was associated with about a two-day shorter median hospital length of stay after coronary bypass.
Why two days is the number that moves budgets
Inpatient days are among the largest controllable costs in a surgical episode. A two-day reduction, multiplied across a cardiac service line, is the kind of figure that shows up in a hospital's financial model — which is why length-of-stay, not pain, is often what gets a non-drug adjunct adopted at the institutional level. This is also the outcome that maps most directly onto value-based and remote-monitoring economics.
The study design
Length of stay was measured from surgical procedure to discharge order in calendar days. Median rather than mean was the appropriate summary statistic for this endpoint because hospital stays have a skewed distribution — a few very long stays can inflate the mean. The two-day shorter median stay reflects a real shift in the central tendency of the distribution, not simply a reduction in outliers. This is the kind of measurement that hospital administrators recognize as clinically and financially meaningful.
What this means in practice
Two days less in a cardiac ICU or step-down unit means two fewer days of hospital-acquired infection risk, two fewer days of deconditioning, and two fewer days of separation from the home environment where recovery continues. It also means two fewer days of hospital billing — relevant both to the payer and, in high-deductible plans, to the patient. For a cardiac surgery program running 300 CABG cases per year, a two-day reduction per patient is 600 inpatient days recovered — a meaningful operational figure.
Compared to the standard alternative
Enhanced Recovery After Surgery (ERAS) protocols for cardiac surgery are specifically designed to reduce length of stay through early mobilization, multimodal analgesia, and goal-directed care. These protocols are resource-intensive. tPEMF fits naturally within ERAS: it is compatible with all existing protocol components, adds no nursing burden, and contributes an additional mechanism-driven analgesic layer that ERAS protocols do not currently include. The length-of-stay reduction attributed to tPEMF may be partially additive with what ERAS protocols already achieve.
