Same-Day Discharge After Minimally Invasive Colectomy

Trends in use of outpatient minimally-invasive adrenalectomy: A population-based analysis

PURPOSE

To examine temporal trends and outcomes of outpatient adrenalectomy in a population-based sample.

METHODS

We performed a retrospective cohort study using the Healthcare Cost and Utilization Project's State Inpatient and State Ambulatory Surgery Databases, 2016-2020. Patients undergoing minimally invasive adrenalectomy were identified using billing codes. The primary exposure was admission status defined by length of stay. Outcomes included temporal trend in admission type, readmission rates and costs.

RESULTS

Among 4431 adrenalectomies, 51.3 ​% were performed in the outpatient setting. The majority were observed overnight with only 100 patients (2.3 ​%) discharged same-day. Outpatient adrenalectomy increased annually from 44.1 ​% in 2016 to 59.2 ​% in 2020 (p ​< ​0.01). Median costs were similar with a risk-adjusted marginal difference of $179 (same-day: $9565 vs overnight $9491; p ​= ​0.81). Odds of readmission were similar between same-day and overnight stays (OR 0.18; p ​= ​0.10).

CONCLUSION

Given similar costs and readmission rates, case selection and surgeon expertise should continue to guide decision-making on same-day adrenalectomy.

National trends and costs of same day discharge in patients undergoing elective minimally invasive colectomy

BACKGROUND

Enhanced Recovery Pathways (ERPs) have enabled safe same day discharge (SDD) of select patients after elective minimally invasive colectomy. We aimed to analyse the financial impact of SDD in these cases.

METHODS

We queried the Nationwide Readmission Database (2016-2019) and included patients with a hospital length of stay ≤2 days after minimally invasive elective colectomy. Propensity score matched pairs of patients discharged on the day of the operation and those discharged on post operative day 1 or 2 were compared. Our primary outcome was the combined cost of hospitalization and readmission.

RESULTS

SDD patients had lower comorbidity (33 ​% vs 21 ​%) and illness severity (79 ​% vs 63 ​%), more Medicare insurance (44 ​% vs 38 ​%), and more benign neoplasms (52 ​% vs 17 ​%). Most SDD patients underwent right colectomy (89 ​%). Across 647 matched pairs, total cost was significantly lower in SDD patients ($8000 vs. $12,900; p ​< ​0.001) due to cheaper index hospitalizations. No difference in readmission rates or costs emerged.

CONCLUSION

SDD reduced costs of index hospitalization and may be cost-effective in a select cohort of healthier patients.

Same-day Ileostomy Closure Discharge Reduces Costs Without Compromising Outcomes: An Economic Analysis

OBJECTIVE

This study aims to assess the costs of a same-day discharge (SDD) enhanced recovery pathway for diverting loop ileostomy (DLI) closure compared with a standard institutional enhanced recovery protocol.

BACKGROUND

Every year, 50,155 patients in the United States undergo temporary stoma reversal. While ambulatory stoma closure has shown promise, widespread adoption remains slow. This study builds on previous research, focusing on the costs of a novel SDD protocol introduced in 2020.

METHODS

A retrospective case-control study was conducted at Mayo Clinic, Rochester, Minnesota, and Mayo Clinic, Jacksonville, Florida, comparing patients undergoing SDD DLI closure from August 2020 to February 2023 to those in a matched cohort receiving standard inpatient enhanced recovery protocol. Patients were matched based on age, sex, american society of anesthesiologists score, surgery period, and hospital. Primary outcomes included direct hospitalization and additional costs in the 30 days postdischarge.

RESULTS

The SDD group (n = 118) demonstrated a significant reduction in median index episode hospitalization and 30-day postoperative costs compared with the inpatient group (n = 236), with savings of $4827 per patient. Complication rates were similar, and so were readmission and reoperation rates.

CONCLUSIONS

Implementation of the SDD for DLI closure is associated with substantial cost savings without compromising patient outcomes. The study advocates for a shift towards SDD protocols, offering economic benefits and potential improvements in health care resource utilization.

Same-day discharge in craniotomy: A systematic review and meta-analysis

BACKGROUND

Traditionally, patients undergoing craniotomy were subject to extended hospital stays for intensive monitoring and management of potential complications. However, with the evolution of surgical methods, anesthesia, and postoperative protocols, the feasibility and interest in same-day discharge (SDD) are growing. This study aimed to evaluate whether same-day discharge is a safe and feasible approach in craniotomy through a meta-analysis of the available literature.

METHODS

Following PRISMA guidelines, a comprehensive search was conducted across Medline, Embase, Cochrane, and Web of Science databases from inception to December 2023. Eligible studies comprised reports in English with a minimum of 4 patients who underwent craniotomies and were discharged with same-day discharge, whether single-arm or comparative with normal discharge. Single proportion analysis with 95 % confidence interval (CI) was used to pool the studies and Odds Ratio (OR) with 95 % CI was used to measure effects in comparative analysis. A random-effects model was adopted. Endpoints included success and failure of pre-planned same-day discharge, and postoperative complications throughout the hospital stay (until discharge), these complications were further categorized into major and minor complications. Also, need for reoperation, readmission within 24 h, readmission after 24 h, and mortality.

RESULTS

Seven observational studies were included. Five studies were included in the single-arm analysis, comprising data from 715 patients. Four studies comprising 731 patients were included in the comparative analysis, of whom 233 were discharged on SDD, and 498 were discharged normally. The analysis revealed a success rate of 88 % (95 % CI, 83 %-94 %), readmission to the hospital within the initial 24 h rate of 2 % (95 % CI, 1 %-2 %), readmission after 24 h rate of 1 % (95 % CI, 0 %-2 %;), total postoperative complications until discharge rate of 2 % (95 % CI, 1 %-4 %), major complications rate of 0 % (95 % CI, 0 %-0 %), minor complications rate of 2 % (95 % CI, 1 %-4 %), and mortality rate of 0 % (95 % CI, 0 %-0 %). Comparative analysis for complications and mortality showed no difference between both approaches.

CONCLUSION

This systematic review and meta-analysis identified that same-day discharge in craniotomy for selected patients, as well as for tumor resection craniotomies, is highly feasible and safe, with a high success rate, low failure, and reoperation rates. Moreover, for selected patients, no evidence of harm in same-day discharge was identified when compared with normal discharge. Consequently, same-day discharge may be considered a viable option, provided appropriate selection criteria are employed.

Same-Day Discharge After a Minimally Invasive Colectomy: A Successful Approach to Patient Selection

BACKGROUND

Enhanced Recovery After Surgery (ERAS) protocols have been shown to decrease inpatient length of stay (LOS) and improve surgical outcomes in elective abdominal colorectal procedures. Discharging a patient home after a minimally invasive colectomy on the same calendar day is a multifactorial decision that takes into account the patient's decision and baseline condition, social factors, intraoperative findings, and postoperative recovery status. The aim of this study is to evaluate the outcomes of same-day discharge (SDD) following minimally invasive colectomy within an ERAS protocol in a community hospital setting in Houston, Texas.

METHODS

In this retrospective cohort study, all consecutive elective cases were performed by a single surgeon from April 2022 to April 2023. This retrospective analysis aims to report a single senior surgeon's experience of the safety, feasibility, and benefits of same-day discharge after minimally invasive colectomy in preselected patients. Same-day discharge was defined as a discharge on the same calendar day without an overnight stay. Differences between specific groups were compared using the Fisher's exact test and Mann-Whitney U test.

RESULTS

Of 86 non-emergent colectomies, 41 patients (47.7%) were successfully discharged on the same day. The median age of the patients was 63.50 years (interquartile range (IQR) 18). The cohort included 37 females (43%) and 49 males (57%). The median LOS was one day. The median operating time was 148.50 minutes (IQR 68.25). The median intraoperative fluid usage was 1500 mL (IQR 36.25), and the median estimated blood loss (EBL) was 25 mL (IQR 36.25). No readmissions among the SDD patients (0%), while three readmissions were reported in patients who stayed overnight (3.4%).  Conclusion: Same-day discharge after a minimally invasive colectomy is feasible when there is a well-established ERAS protocol and there is adequate education for patients and staff. Adequate patient selection is crucial. Patients with multiple comorbidities and a lack of a support network are not suitable candidates.

Using preoperative C-reactive protein levels to predict anastomotic leaks and other complications after elective colorectal surgery: A systematic review and meta-analysis

AIM

While postoperative C-reactive protein (CRP) is used routinely as an early indicator of anastomotic leak (AL), preoperative CRP remains to be established as a potential predictor of AL for elective colorectal surgery. The aim of this systematic review and meta-analysis is to examine the association between preoperative CRP and postoperative complications including AL.

METHOD

MEDLINE, EMBASE, Web of Science, PubMed, Cochrane Library and CINAHL databases were searched. Studies with reported preoperative CRP values and short-term surgical outcomes after elective colorectal surgery were included. An inverse variance random effects meta-analysis was performed for all meta-analysed outcomes to determine if patients with or without complications and AL differed in their preoperative CRP levels. Risk of bias was assessed with MINORS and certainty of evidence with GRADE.

RESULTS

From 1945 citations, 23 studies evaluating 7147 patients were included. Patients experiencing postoperative infective complications had significantly greater preoperative CRP values [eight studies, n = 2421 patients, mean difference (MD) 8.0, 95% CI 3.77-12.23, p < 0.01]. A significant interaction was observed with subgroup analysis based on whether patients were undergoing surgery for inflammatory bowel disease (X2 = 8.99, p < 0.01). Preoperative CRP values were not significantly different between patients experiencing and not experiencing AL (seven studies, n = 3317, MD 2.15, 95% CI -2.35 to 6.66, p = 0.35), nor were they different between patients experiencing and not experiencing overall postoperative morbidity (nine studies, n = 2958, MD 4.54, 95% CI -2.55 to 11.62, p = 0.31) after elective colorectal surgery.

CONCLUSION

Higher preoperative CRP levels are associated with increased rates of overall infective complications, but not with AL alone or with overall morbidity in patients undergoing elective colorectal surgery.

Rethinking postoperative care: same-day ileostomy closure discharge improves patient outcomes

BACKGROUND

The evolution of enhanced recovery pathways (ERPs) in colon and rectal surgery has led to the development of same-day discharge (SDD) procedures for selected patients. Early discharge after diverting loop ileostomy (DLI) closure was first described in 2003. However, its widespread adoption remains limited, with SDD accounting for only 3.2% of all DLI closures in 2005-2006, according to the American College of Surgeons National Surgical Quality Improvement Program database, and rising to just 4.1% by 2016. This study aimed to compare the outcomes of SDD DLI closure with those of DLI closure after the standard ERP.

METHODS

A retrospective case-matched study compared 125 patients undergoing SDD DLI closure with 250 patients undergoing DLI closure after the standard ERP based on age (±1 year), sex, American Society of Anesthesiologists score, body mass index, surgery date (±2 months), underlying disease, and hospital site. The primary outcome was comparative 30-day complication rates.

RESULTS

Patients in the traditional ERP group received more intraoperative fluids (1221.1 ± 416.6 vs 1039.0 ± 368.3 mL, P < .001) but had similar estimated blood loss. Ten patients (8%) in the SDD-ERP group failed SDD. The 30-day postoperative complication rate was significantly lower in the SDD group (14.8%) than the standard ERP group (25.7%, P = .025). This difference was primarily driven by a lower incidence of ileus in the SDD group (9.6% vs 14.8%, P = .034). There were no significant differences in readmission rate (9.6% of SDD-ERP vs 9.2% of standard ERP, P = .900) and reoperation rates (3.2% of SDD-ERP vs 2.4% of standard ERP, P = .650).

CONCLUSION

SDD ileostomy closure is a safe, feasible, and effective procedure associated with fewer complications than the present study's standard ERP. This could represent a new standard of care. Further prospective trials are required to confirm the findings of this study.

Ambulatory Robotic Colectomy: Factors Affecting and Affected by Postoperative Opioid Use

BACKGROUND

The ongoing opioid crisis demands an investigation into the factors driving postoperative opioid use. Ambulatory robotic colectomies are an emerging concept in colorectal surgery, but concerns persist surrounding adequate pain control for these patients who are discharged very early. We sought to identify key factors affecting recovery room opioid use (ROU) and additional outpatient opioid prescriptions (AOP) after ambulatory robotic colectomies.

METHODS

This was a single-institution retrospective review of ambulatory robotic colon resections performed between 2019 and 2022. Patients were included if they discharged on the same day (SDD) or postoperative day 1 (POD1). Outcomes of interest included ROU [measured in parenteral morphine milligram equivalents (MMEs)], AOP (written between PODs 2 to 7), postoperative emergency department presentations, and readmissions.

RESULTS

Two hundred nineteen cases were examined, 48 of which underwent SDD. The mean ROU was 29.4 MME, and 8.7% of patients required AOP. Between SDD and POD1 patients, there were no differences in postoperative emergency department presentations, readmissions, recovery opioid use, or additional outpatient opioid scripts. Older age was associated with a lower ROU (-0.54 MME for each additional year). Older age, a higher body mass index, and right-sided colectomies were also more likely to use zero ROU. Readmissions were strongly associated with lower ROU. Among SDD patients, lower ROU was also associated with higher rates of AOP.

CONCLUSION

Ambulatory robotic colectomies and SDD can be performed with low opioid use and readmission rates. Notably, we found an association between low ROU and more readmission, and, in some cases, higher AOP. This suggests that adequate pain control during the postoperative recovery phase is a crucial component of reducing these negative outcomes.

Predictive Factors for Successful Same-Day Discharge After Minimally Invasive Colectomy and Stoma Reversal

BACKGROUND

Same-day discharge after minimally invasive colorectal surgery is a safe, effective practice in specific patients that can enhance the efficiency of enhanced recovery pathways.

OBJECTIVE

To identify predictive factors associated with success or failure of same-day discharge.

DESIGN

Prospective cohort study from January 2020 to March 2023.

SETTINGS

Tertiary colorectal center.

PATIENTS

Adult patients eligible for same-day discharge with remote postdischarge follow-up included those with minimal comorbidities, residing near the hospital, having sufficient home support, and owning a mobile device.

INTERVENTIONS

Patients were discharged on the day of surgery upon meeting specific criteria, including adequate pain control, tolerance of oral intake, independent mobility, urination, and the absence of complications. Successful same-day discharge was defined as discharge on the day of surgery without unplanned visits in the first 72 hours.

MAIN OUTCOME MEASURES

Factors associated with successful or failed same-day discharge after minimally invasive colorectal surgery.

RESULTS

A total of 175 patients (85.3%) were discharged on the day of surgery, with 14 patients (8%) having an unplanned visit within 72 hours. Overall, 161 patients (78.5%) were categorized as same-day discharge success and 44 patients (21.5%) as same-day discharge failure. The same-day discharge failure group had a higher Charlson Comorbidity Index (3.7 vs 2.8, p = 0.03). Mean length of stay (0.8 vs 3.0, p = 0.00), 30-day complications (10% vs 48%, p = 0.00), and readmissions (8% vs 27%, p = 0.00) were higher in the same-day discharge failure group. Regression analysis showed that failed same-day discharge was associated with higher comorbidities (OR 0.79; 95% CI, 0.66-0.95) and prolonged postanesthesia care unit time (OR 0.99; 95% CI, 0.99-0.99). Individuals who received a regional nerve block (OR 4.1; 95% CI, 1.2-14) and those who did not consume postoperative opioids (OR 4.6; 95% CI, 1-21) were more likely to have successful same-day discharge.

LIMITATIONS

Single-center study.

CONCLUSIONS

Our findings indicate that comorbidities and prolonged postanesthesia care unit stays were associated with same-day discharge failure, whereas regional nerve blocks and minimal postoperative opioids were related to success. These factors may inform future research aiming to enhance colorectal surgery recovery protocols. See Video Abstract .

Quality indicators for ambulatory colectomy: literature search and expert consensus

BACKGROUND

Care for patients undergoing elective colectomy has become increasingly standardized using Enhanced Recovery Programs (ERP). ERP, encorporating minimally invasive surgery (MIS), decreased postoperative morbidity and length of stay (LOS). However, disruptive changes are needed to safely introduce colectomy in an ambulatory or same-day discharge (SDD) setting. Few research groups showed the feasibility of ambulatory colectomy. So far, no minimum standards for the quality of care of this procedure have been defined. This study aims to identify quality indicators (QIs) that assess the quality of care for ambulatory colectomy.

METHODS

A literature search was performed to identify recommendations for ambulatory colectomy. Based on that search, a set of QIs was identified and categorized into seven domains: preparation of the patient (pre-admission), anesthesia, surgery, in-hospital monitoring, home monitoring, feasibility, and clinical outcomes. This list was presented to a panel of international experts (surgeons and anesthesiologists) in a 1 round Delphi to assess the relevance of the proposed indicators.

RESULTS

Based on the literature search (2010-2021), 3841 results were screened on title and abstract for relevant information. Nine papers were withheld to identify the first set of QIs (n = 155). After excluding duplicates and outdated QIs, this longlist was narrowed down to 88 indicators. Afterward, consensus was reached in a 1 round Delphi on a final list of 32 QIs, aiming to be a comprehensive set to evaluate the quality of ambulatory colectomy care.

CONCLUSION

We propose a list of 32 QI to guide and evaluate the implementation of ambulatory colectomy.

Enhanced recovery and same-day discharge hospital stay: speed versus safety?

Same-day ambulatory major surgery is evolving, but requires more study regarding patient selection and safety.

Same day discharge after minimally invasive adrenalectomy: a national study

BACKGROUND

Same day discharge (SDD) may be considered in some patients undergoing minimally invasive adrenalectomy (MIA). Recent studies have demonstrated similar outcomes between SDD and admitted patients; however, most excluded pheochromocytoma and adrenal metastases. This study evaluates 30-day complications and hospital readmission in a large cohort of patients undergoing MIA.

METHODS

Adult patients undergoing MIA (2010-2020) for benign adrenal disorders, pheochromocytoma, and adrenal metastases were identified within the ACS-NSQIP database. Comparisons between patients having SDD versus admission were performed. Factors associated with 30-day complications and unplanned readmission were evaluated by multivariable regression modeling.

RESULTS

Of 7316 patients who underwent MIA, 254 had SDD. Baseline characteristics were similar between groups, although SDD patients had lower ASA class (p < 0.001) and were more likely to undergo MIA for nonfunctioning adenoma or primary aldosteronism (p = 0.001). After adjusting for covariates, higher ASA class and presence of medical comorbidities were associated with increased complications (p < 0.001; p < 0.05) and unplanned readmission (p < 0.001; p < 0.05). Additionally, prolonged operative time was associated with 30-day complications (p < 0.001). Notably, SDD was not associated with increased complications (OR 0.78, 95% CI 0.38-1.61, p = 0.502) or unplanned readmission (OR 0.76, 95% CI 0.35-1.64, p = 0.490). The rate of SDD for MIA increased from 1.48% in 2017 to 10.81% in 2020.

CONCLUSIONS

Not all patients undergoing MIA should have SDD; however, the current analysis demonstrates a trend toward SDD and supports its safety in select patients with adrenal metastases and benign adrenal disorders including pheochromocytoma.

Same-day discharge (SDD) vs standard enhanced recovery after surgery (ERAS) protocols for major colorectal surgery: a systematic review

BACKGROUND

Enhanced recovery after surgery (ERAS) programs are well-established, resulting in improved outcomes and shorter length of hospital stay (LOS). Same-day discharge (SDD), or "hyper-ERAS", is a natural progression of ERAS. This systematic review aims to compare the safety and efficacy of SDD against conventional ERAS in colorectal surgery.

METHODS

The protocol was prospectively registered in PROSPERO (394793). A systematic search was performed in major databases to identify relevant articles, and a narrative systematic review was performed. Primary outcomes were readmission rates and length of hospital stay (LOS). Secondary outcomes were operative time and blood loss, postoperative pain, morbidity, nausea or vomiting, and patient satisfaction. Risks of bias was assessed using the ROBINS-I tool.

RESULTS

Thirteen studies were included, with five single-arm and eight comparative studies, of which one was a randomised controlled trial. This comprised a total of 38,854 patients (SDD: 1622; ERAS: 37,232). Of the 1622 patients on the SDD pathway, 1590 patients (98%) were successfully discharged within 24 h of surgery. While most studies had an overall low risk of bias, there was considerable variability in inclusion criteria, types of surgery or anaesthesia, and discharge criteria. SDD resulted in a significantly reduced postoperative LOS, without increasing risk of 30-day readmission. Intraoperative blood loss and postoperative morbidity rates were comparable between both groups. Operative duration was shorter in the SDD group. Patient-reported satisfaction was high in the SDD cohort.

CONCLUSION

SDD protocols appear to be safe and feasible in selected patients undergoing major colorectal operations. Randomised controlled trials are necessary to further substantiate these findings.

Beyond enhanced recovery after surgery (ERAS): Evolving minimally invasive colectomy from multi-day admissions to same-day discharge

INTRODUCTION

Early discharge is increasingly important in the resource-limited COVID era. Some groups have reported early experiences with same day discharge (SDD) after colectomy. We implemented a routine SDD protocol and report the evolution in our program's outcomes.

METHODS

We studied a retrospective cohort of robotic colorectal surgeries from 2016 to 2022. Colectomies were analyzed as a sub-group and stratified by year.

RESULTS

The cohort comprised 535 cases, of which 483 were colectomies. Annual case volume increased from 58 to 180 cases (p < 0.001). Operative console time concordantly decreased by 33% (p < 0.001). Average length of stay decreased from five to one days. By 2022, 58% of colectomies were selectively discharged on the same day of surgery. Complication and readmission rates remained constant.

CONCLUSIONS

SDD is feasible and safe in selected patients. We illustrate the practical evolution of a surgical practice toward routine SDD, and discuss the factors we found critical to this transition.
