In a recent post So, you think you can walk? I outlined some of the evidence, rationale, logic, and decision making involved in acute care physical therapist practice. I discussed the important of conceptualizing and studying physical therapists impact “beyond function.”
The authors modeled cost savings utilizing best-case and most conservative estimates of length of stay reductions, upfront costs, and other factors based on existing published data and their specific quality improvement project. The quality improvement project undertaken at Johns Hopkins University within the medical ICU included full time, dedicated physical therapists and occupational therapists in the medical ICU. The vision:
A multidisciplinary team focused on reducing heavy sedation and increasing MICU staffing to include full-time physical and occupational therapists with new consultation guidelines.
In total, the early rehabilitation program cost the hospital approximately $358,00 more per year than the previous standard of care. So, what did the results say? Within 1 year, ICU length of stay decreased by an average of 23% while medical ICU admissions increased by over 20%. An $818,000 per year net savings after accounting for start up costs (approximately $358,000) was observed. Conclusions:
A financial model, based on actual experience and published data, projects that investment in an ICU early rehabilitation program can generate net financial savings for U.S. hospitals. Even under the most conservative assumptions, the projected net cost of implementing such a program is modest relative to the substantial improvements in patient outcomes demonstrated by ICU early rehabilitation programs.
Results: Compared with before the quality improvement project, benzodiazepine use decreased markedly (proportion of MICU days that patients received benzodiazepines [50% vs 25%, P=.002]), with lower median daily sedative doses (47 vs 15 mg midazolam equivalents [P=.09] and 71 vs 24 mg morphine equivalents [P=.01]). Patients had improved sedation and delirium status (MICU days alert [30% vs 67%, P<.001] and not delirious [21% vs 53%, P=.003]). There were a greater median number of rehabilitation treatments per patient (1 vs 7, P<.001) with a higher level of functional mobility (treatments involving sitting or greater mobility, 56% vs 78%, P=.03). Hospital administrative data demonstrated that across all MICU patients, there was a decrease in intensive care unit and hospital length of stay by 2.1 (95% confidence interval: 0.4-3.8) and 3.1 (0.3-5.9) days, respectively, and a 20% increase in MICU admissions compared with the same period in the prior year.
Conclusions: Using a quality improvement process, intensive care unit delirium, physical rehabilitation, and functional mobility were markedly improved and associated with decreased length of stay.
Early mobility in acute care. It’s important.
The physical therapist in acute care. A vital part of the care team.
Looking beyond function to conceptualize and understand the impact of the physical therapist? Necessary.
