Large-scale ERAS program reduces postoperative LOS, complications

 

Key clinical point: An Enhanced Recovery After Surgery program aimed at improving inpatient safety significantly reduced length of stay and complication rates at 20 California hospitals.

Major finding: After the ERAS program was implemented, hospital LOS decreased from 5.1 to 4.2 days in the colorectal resection group and from 3.6 to 3.2 days in the hip fracture group, and complication rates decreased from 18.1% to 14.7% and from 30.8% to 24.9%, respectively.

Data source: A “pre-post” comparison study of patients’ safety outcomes after implementation of an ERAS program, which involved 15,849 surgical patients at 20 hospitals.

Disclosures: The Gordon and Betty Moore Foundation, the Permanente Medical Group, the Kaiser Foundation Health Plan, and the National Institutes of Health funded the study. Dr. Liu and his associates reported having no relevant financial disclosures.

Implementation science taken to the next level

Findings from Liu et al. have clinical, research, and policy relevance. First, they went beyond select surgical procedures from single hospitals. The investigators have robustly taken implementation science to the next level, thus showing that thoughtfully planned quality-improvement endeavors that are integrated with robust research evaluation measures can positively affect our surgical patients. In a similar vein, these results underscore the value proposition of research conducted in large health care systems that goes beyond the limitation of traditional stand-alone hospitals, such as small sample size and referral and practice biases. [In addition,] this investigation raises many and exciting future research opportunities to an eager audience of stakeholders. What are the cost implications of such efforts? How can we better leverage electronic health records with smart tools to better implement and measure the effects of the ERAS program and other quality and safety initiatives? [We also] need to be mindful of its unintended consequences on vulnerable populations and financially strained hospitals.

FROM JAMA SURGERY

Enhanced Recovery After Surgery (ERAS), a program implemented by Kaiser Permanente Northern California – a multihospital integrated health system – significantly reduced length of stay and complication rates, according to a report published in JAMA Surgery.

Beginning in 2014, when the ERAS program was implemented in 20 Kaiser hospitals, progress was made on the goal of improving inpatient safety, as well as improvements in-hospital mortality, rates of early ambulation, patient nutrition, and reduced opioid use, said Vincent X. Liu, MD, of the division of research, Kaiser Permanente Oakland, and his associates. Those outcomes were studied in the context of a similar group of patients in other, non-ERAS hospitals to determine the degree of change in each area.

The investigators assessed the safety outcomes of 15,849 surgical patients 1 year before and 1 year after implementation of an ERAS program across a diverse set of northern California hospitals “that differ significantly in size, patient case mix, teaching status, geographic location, and on-site specialty service availability.” They focused on two very different patient groups: people undergoing elective colorectal resection and people undergoing emergency repair of a hip fracture.

ERAS aimed to reduce opioid use by encouraging multimodal analgesia, which included pre- and postoperative IV acetaminophen and NSAIDs, perioperative IV lidocaine, or peripheral nerve blocks. It encouraged ambulation within 12 hours of surgery completion and a daily goal of walking at least 21 feet during the first 3 postoperative days.

The program enhanced patient nutrition by reducing prolonged preoperative fasting, providing a high-carbohydrate beverage 2-4 hours before surgery, and allowing solids 8-12 hours before surgery. It also provided food within 12 hours of completing surgery. ERAS also encouraged patient engagement in care by use of educational materials and a calendar that detailed what the care process would entail. For clinicians, ERAS provided new electronic tools such as electronic medical record order sets to facilitate standardized practice.

In the first phase of their study, Dr. Liu and his associates assessed changes over time in patient safety outcomes among 3,768 patients undergoing elective colorectal resection and 5,002 undergoing emergency hip fracture repair.

Hospital length of stay decreased significantly after implementation of ERAS, from 5.1 to 4.2 days in the colorectal resection group and from 3.6 to 3.2 days in the hip fracture group. Complication rates decreased from 18.1% to 14.7% and from 30.8% to 24.9%, respectively. Early ambulation rates increased substantially, from 22.3% to 56.5% and from 2.8% to 21.2%, respectively.

The rate of improved nutrition rose from 13.0% to 39.2% in the colorectal resection group and from 45.6% to 57.1% in the hip repair group. And the total dose of morphine equivalents dropped from 52.4 to 30.6 and from 38.9 to 27.0, respectively (JAMA Surg. 2017 May 10. doi: 10.1001/jamasurg.2017.1032).

In the second phase of the study, the investigators compared these changes against the outcomes of two comparator groups who underwent similar surgeries (5,556 resection comparators and 1,523 hip repair comparators) during the same time frame but in hospitals that did not implement the ERAS program.

In this analysis, LOS was significantly shorter and complication rates were significantly lower for both procedures at the hospitals where the intervention was implemented, compared with the other hospitals. In-hospital mortality, opioid use, early ambulation, and discharge to home rather than a rehabilitation facility also favored the intervention groups.

“This study demonstrates the effectiveness of a systems-level approach to ERAS program implementation, even across widely divergent target populations,” Dr. Liu and his associates said.

The Gordon and Betty Moore Foundation, the Permanente Medical Group, the Kaiser Foundation Health Plan, and the National Institutes of Health funded the study. Dr. Liu and his associates reported having no relevant financial disclosures.
