Reduced length of stay and 30-day readmission rate on an inpatient vascular surgery service

Novel Electronic Health Records-Based Consultation Workflow Improves Time to Operating Room for Vascular Surgery Patients in an Acute Setting

BACKGROUND

Inefficient clinical workflows can have downstream effects of increased costs, poor resource utilization, and worse patient outcomes. The surgical consultation process can be complex with unclear communication, potentially delaying care for patients requiring time-sensitive intervention in an acute setting. A novel electronic health records (EHR)-based workflow was implemented to improve the consultation process. After implementation, we assessed the impact of this initiative in patients requiring vascular surgery consultation.

METHODS

An EHR-driven consultation workflow was implemented at a single institution, standardizing the process across all consulting services. This order-initiated workflow automated notification to clinicians of consult requests, communication of patient data, patient addition to consultants' lists, and tracking consult completion. Preimplementation (1/1/2020-1/31/2022) and postimplementation (2/1/2022-12/4/2022) vascular surgery consultation cohorts were compared to evaluate the impact of this initiative on timeliness of care.

RESULTS

There were 554 inpatient vascular surgery consultations (255 preimplementation and 299 postimplementation); 45 and 76 consults required surgery before and after implementation, respectively. The novel workflow resulted in placement of a consult note 32 min faster than preimplementation (preimplementation: 462 min, postimplementation: 430 min, P = 0.001) for all vascular surgery consults. Furthermore, vascular surgery patients with ASA class III or IV status requiring an urgent or emergent operation were transported to the operating room 63.3% faster after implementation of the workflow (preimplementation: 284 min, postimplementation: 180 min, P = 0.02). There were no differences in procedure duration, postoperative disposition, or intraoperative complication rates.

CONCLUSIONS

We implemented a novel workflow utilizing the EHR to standardize and automate the consultation process in the acute inpatient setting. This institutional initiative significantly improved timeliness of care for vascular surgery patients, including decreased time to operation. Innovations such as this can be further disseminated across shared EHR platforms across institutions, representing a powerful tool to increase the value of care in vascular surgery and healthcare overall.

Interventions to Prevent Readmissions in Hospitalized Peripheral Vascular Surgery Patients: A Systematic Review

A large proportion of peripheral vascular patients worldwide experience unplanned hospital readmissions after inpatient vascular surgery. This review was conducted to identify acute care and post-discharge interventions that may help in reducing unplanned vascular surgery readmissions. A computer-based search of four databases was conducted July 2021 for original research reports published 2000 to 2021. Eight studies met inclusion criteria, with interventions including multidisciplinary care teams, advance practice provider discharge coordination, individualized case management, home care nursing, early primary care provider or telephone follow-up, and telehealth driven follow up evaluated. Some reductions in readmission rates were associated with most interventions but were inconsistent across studies. Further research is necessary to clarify and validate these findings, incorporate patient perspectives, and explore the role of technology-based interventions. This work is key to improving the patient's experience, reduce healthcare costs, and strengthen the quality of vascular surgery care.

Implementation of Transitional Care Planning is Associated with Reduced Readmission Rates in Patients Undergoing Lower Extremity Bypass Surgery for Peripheral Arterial Disease

OBJECTIVES

Patients undergoing lower extremity bypasses (LEB) are at high risk of developing post-discharge complications requiring readmission. Health systems have developed several strategies to mitigate this risk. One such measure is developing comprehensive Transition Care Planning (TCP), which includes phone calls to patients after being discharged from the hospital. Our study aimed to assess short-term readmission, mortality, and amputation rates of patients who participated in TCP by completing at least one post-discharge follow-up phone call after undergoing LEB for revascularization for peripheral artery disease (PAD).

METHODS

A retrospective review was completed for patients who underwent LEB surgery between January 2010 and January 2020 to treat PAD at Penn State Hershey Medical Center. Immediate discharge follow-up was done via telephone calls using a standardized script. Patients were then divided into two groups, those who did not have a successful follow-up call (Group I) and those who had at least one successful follow-up call within seven days after discharge (Group II). Univariate analysis was used to compare preoperative demographics, intraoperative variables, and postoperative outcomes. The probability of Readmission and risk factors contributing to it were computed using multiple stepwise forward regression analyses. Epidemiological analysis was done to evaluate the risk of readmission in the group receiving post-discharge follow-up calls.

RESULTS

A total of 457 patients underwent LEB from 2010 to 2020 and qualified for inclusion in the study. Among these patients, 126 (27.6%) did not have a successful post-discharge follow-up call (Group I), whereas 331 (72.4%) patients did complete a successful call (Group II). The mean age of patients was 66.7 years. There were no significant differences in preoperative baseline patient characteristics or intraoperative factors. Patients who completed a successful call had lower readmission rates within thirty days of the operation (8.8% vs. 17.5%, p=0.008), and this was sustained in multivariate analysis (AOR: 0.18, [CI: 0.05-0.66], p=0.009). However, no differences were observed for thirty-day mortality (Group-I: 3.2% vs. Group-II: 1.2%, p=0.152) or amputation (Group-I: 9.6% vs. Group II 5.9%, p=0.162). Among those who had a successful call, patients with a history of smoking (AOR: 4.05 [CI: 1.21, 17.12] p=0.025], diabetes mellitus (AOR: 3.42 [CI:1.35,8.7] p=0.01) and myocardial infarction (AOR: 7.15 [CI:1.76, 20.1] p=0.006) had much higher chances of readmission. Risk analysis using epidemiological methods showed that by receiving a call, the risk of readmission could be dropped to half (RR: 0.50 [CI: 0.30, 0.84]), with an attributable risk reduction of -8.7% (CI:-15.9%,-1.4%).

CONCLUSIONS

This single-institution retrospective study demonstrates the importance of immediate discharge follow-up phone calls in patients who undergo open lower extremity revascularization to reduce thirty-day readmissions. Our analysis showed patients who received immediate follow-up phone calls were less likely to be readmitted to the hospital. The development of reliable and efficient systems to enhance immediate discharge follow-up in vascular surgery patients is pivotal to improving quality of care, preventing readmissions, and reducing healthcare costs.

Impact of Length of Stay on Readmission in Hospitalized Patients

Background Readmission and length of stay (LOS) are two hospital-level metrics commonly used to assess the performance of hospitalist groups. Healthcare systems implement strategies aimed at reducing both. It is possible that tactics aimed at improving one measure in individual patients may adversely impact the other.  Objective We sought to analyze the impact of length of stay on readmission risk in an inpatient general medical population to assess whether patients with a lower length of stays were readmitted more frequently to the hospital. Methods We performed a retrospective analysis of inpatient adult patients admitted to our institution between January 2016 and December 2019. We recorded demographic variables and the outcomes of LOS and 30-day readmission. We excluded patients who expired, left against medical advice, or were transferred to other hospitals. We performed both univariate and multivariate analyses. Results There were 91,723 patients included in the study of which 10,598 (11.6%) were readmitted. The geometric LOS for all patients was 5.37 days and was higher in readmitted patients (6.87 vs 5.18 days, respectively, p < 0.001). Patients with higher readmission rates were older, had a higher proportion of male gender, African-American ethnicity, and were more likely to have Medicare or Medicaid payors. After performing a multivariate regression analysis, we found that a high LOS was associated with a higher likelihood of readmission (P < 0.001). Conclusion Contrary to our initial hypothesis, we found that general medical patients with a higher LOS had a higher likelihood of being readmitted to the hospital after adjusting for other variables. It is possible that factors not captured in the current dataset may help explain both the increase in LOS and readmission risk.
