Predictors of postdischarge complications: role of in-hospital length of stay

Early Discharge after Uncomplicated Elective Colectomy and Risk of Postdischarge Complication

BACKGROUND

This was a retrospective cohort study of adult patients undergoing uncomplicated elective colectomy using the NSQIP database from January 2012 to December 2019. A colectomy is deemed uncomplicated if there are no complications reported during the hospitalization. The objective of this study was to examine the association between discharge timing and postdischarge complications in patients who undergo uncomplicated elective colectomy.

STUDY DESIGN

Patients were stratified into an early discharge group if their length of postoperative hospitalization was ≤3 days for laparoscopic or robotic approaches, or ≤5 days for the open approach, and otherwise into delayed discharge groups. The association between early discharge and any postdischarge complication was examined using unadjusted logistic regression after propensity score matching between early and delayed discharge groups.

RESULTS

Of the 113,940 patients included, 77,979, 15,877, and 20,084 patients underwent uncomplicated laparoscopic, robotic, and open colectomy, respectively. After propensity score matching, the odds of a postdischarge complication were lower for the early discharge group in laparoscopic (odds ratio 0.73, 95% CI 0.68 to 0.79) and robotic (odds ratio 0.63, 95% CI 0.52 to 0.76) approaches, and not different in the open approach (odds ratio 1.02, 95% CI 0.91 to 1.15). There were no clinically meaningful differences in the risk of return to the operating room for all surgical approaches.

CONCLUSIONS

Early discharge after uncomplicated colectomy appears to be safe and is associated with lower odds of postdischarge complications in minimally invasive approaches. Our findings suggest that surgical teams practice sound clinical judgments on selecting patients who benefit from early discharge.

A multidisciplinary approach to decreasing length of stay in acute care surgery patients

AIM

To decrease hospital length of stay in acute care surgery patients.

DESIGN

An observational cohort quality improvement project at a single tertiary referral centre.

METHODS

A multidisciplinary team of physicians, nurses, case managers, and physical and occupational therapists was created to identify patients at risk for prolonged length of stay and implement weekly multidisciplinary rounding, with a systematic method of tracking progress in real time. The main outcome measure was hospital length of stay. The observed/expected ratios for length of stay 2 years before (2012-2014) and after (2014-2016) the intervention were compared.

RESULTS

A total of 6,120 patients was analysed. Early identification and action on barriers to discharge created a significant decrease in risk-adjusted acute care surgery patient days per year (96 days) with limited added cost (1-2 hr per week). Patients discharged to home with or without services benefited most.

CONCLUSION

Decreasing length of stay in acute care surgery patients is possible without adding a significant burden to healthcare providers.

IMPACT

We describe a comprehensive, multidisciplinary initiative to decrease the length of stay of acute care surgery patients. Institutions can use existing resources in a sustainable manner to create a significant decrease in patient days per year with limited added cost. REGISTRATION: https://osf.io/zfc3t.

Impact of Operation Time on 30-Day Complications After Adult Spinal Deformity Surgery

STUDY DESIGN

Retrospective analysis of prospectively collected data.

OBJECTIVE

There is a paucity of data on the effect of operative duration on postoperative complications during adult spinal deformity surgery (ASDS). The study attempts to explore and quantify the association between increased operation times and postoperative complications.

METHODS

A retrospective cohort analysis was performed on the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database from 2010 to 2014. Patients (≥18 years of age) from the NSQIP database undergoing ASDS were separated into cohorts based on quartiles of operation duration. Chi-square and multivariate logistic regression models were used to identify risk factors.

RESULTS

A total of 5338 patients met the inclusion criteria and were divided per quartiles based on operative duration in minutes (154, 235, 346, and 1156 minutes). Multivariate logistic regressions revealed that in comparison to the lowest quartile of operative duration, the highest quartile group was associated significantly with length of stay ≥5 days (odds ratio [OR] = 5.85), any complication (OR = 9.88), wound complication (OR = 5.95), pulmonary complication (OR = 2.85, P = .001), venous thromboembolism (OR = 12.37), intra-/postoperative transfusion (OR = 12.77), sepsis (OR = 5.27), reoperations (OR = 1.48), and unplanned readmissions (OR = 1.29). The odds ratio was higher when comparing a higher quartile group with the reference group across all associations. P < .001 unless otherwise noted.

CONCLUSION

ASDS operation time is associated with multiple postoperative complications, including, but not limited to, wound and pulmonary complications, venous thromboembolism, postoperative transfusion, length of stay ≥5 days, sepsis, reoperation, and unplanned readmission.

Predicting length of stay after robotic partial nephrectomy

INTRODUCTION

To investigate factors predictive of length of stay (LOS) after robotic partial nephrectomy (RPN) in an effort to identify patients suitable for RPN with overnight stay at outpatient surgical facilities.

MATERIALS AND METHODS

Retrospective chart review of patients who underwent RPN at Memorial Sloan Kettering Cancer Center from January 2007 to July 2012 was conducted. Univariate and multivariate analyses were performed to identify the main predictors of LOS. The discrimination of the multivariate model was measured using the area under the curve (AUC); tenfold cross-validation was performed to correct for over-fit.

RESULTS

One hundred and eighty-six patients were included in the analysis; 84 (45 %) had LOS of ≤1 day (median LOS 2 day; interquartile range 1-2). On univariate analysis, preoperative variables associated with LOS > 1 included larger tumors (P < 0.0001), lower estimated glomerular filtration rate (P = 0.003), older age (P = 0.006), female gender (P = 0.035), and higher comorbidity score (P = 0.015); operative variables associated with LOS > 1 day included greater estimated blood loss (P < 0.0001) and longer operative (P < 0.0001) and ischemia (P < 0.0001) times. The AUC of the preoperative model was 0.61 (95 % CI 0.52-0.69) after tenfold cross-validation.

CONCLUSIONS

LOS after RPN is influenced by age, gender, medical comorbidities, and tumor size. However, when analyzed retrospectively, these factors had limited ability to predict LOS after RPN with sufficient accuracy to develop a prediction tool.

Factors influencing the length of stay after radical cystectomy: implications for cancer care and perioperative management

INTRODUCTION

Although radical cystectomy (RC) is the gold standard treatment for muscle invasive bladder cancer it is associated with perioperative complications, readmissions, and a prolonged length of hospital stay (PLOS). We explored the perioperative factors associated with a PLOS after RC and subsequent long-term outcomes.

MATERIAL AND METHODS

Consecutive patients with urothelial bladder cancer undergoing RC with curative intent at our institution were classified into two groups: LOS <12 days and PLOS ≥12 days. Clinicopathological variables were compared on univariate and multivariable analysis. Complications, re-admissions, adjuvant chemotherapy use, recurrence free survival (RFS), and overall survival (OS) were compared between the two groups. Competing risk analysis was performed for bladder cancer specific mortality (BCSM).

RESULTS

330 patients were included in the analysis (median LOS = 9 days [IQR = 8-11]) of which, 274 patients (83 %) had a LOS <12 days (median = 8 days [IQR = 7-10]) and 56 patients (17 %) had a PLOS ≥12 days (median = 16 days [IQR = 13-21.5]). Only female gender, older age, and perioperative complications were associated with a PLOS. 90 day readmission rates were similar (p = 0.75). No difference was seen for BCSM, RFS, or adjuvant chemotherapy usage between the two groups. However, OS was significantly worse for PLOS (median OS = 27.7 vs. 45.6 months [p = 0.046]; HR = 1.53 [95 % CI = 1.01-2.33]).

CONCLUSION

Both female and elderly patients should receive preoperative counseling about their increased risk of a PLOS after RC. Patients who experience a PLOS are at greater risk for subsequent all-cause mortality. These patient groups may benefit from proactive interventions.

Postdischarge Complications Predict Reoperation and Mortality after Otolaryngologic Surgery

Objectives

(1) Determine procedure-specific rates of postdischarge complications (PDCs) and their risk factors in the first 30 days following inpatient otolaryngologic surgery. (2) Evaluate association between PDCs and risk of reoperation and mortality.

Study Design

Retrospective cohort study.

Setting

American College of Surgeons National Surgical Quality Improvement Program (2005-2011).

Subjects and Methods

We identified 48,028 adult patients who underwent inpatient otolaryngologic surgery. Outcomes of interest included complications, reoperation, and mortality in the first 30 days following surgery. Statistical analysis included chi-square, t tests, and multivariate regression.

Results

Laryngectomy, lip, and tongue/floor of mouth surgery had the highest PDC rates (8.0%, 7.4%, and 4.1%, respectively). Within the first 48 hours, week, and 2 weeks post discharge, 10%, 44%, and 73% of PDCs occurred, respectively. Common PDCs included surgical site infections (53.6%), other infections (37.4%), and venous thromboembolic events (7.4%). Multivariate analysis demonstrated that increasing age (odds ratio [OR] = 1.01; 95% confidence interval [CI], 1.01-1.02), prolonged operative time (OR = 1.68; 95% CI, 1.39-2.03), hospital stay >1 day (OR = 1.49; 95% CI, 1.18-1.86), and American Society of Anesthesiologists (ASA) class ≥3 (OR = 1.45; 95% CI, 1.18-1.78) were independently associated with PDCs. Patients with PDCs were more likely to die (0.9% vs 0.1%, P < .001) or have a reoperation (10.4% vs 1.2%, P < .001).

Conclusion

This is the first study of overall postdischarge events after otolaryngologic surgery. PDC rates in otolaryngology occur soon after discharge, are procedure specific, and are associated with reoperation and mortality. Targeted procedure-specific triage and follow-up plans for high-risk patients may improve outcomes.

Can laparoscopy for colon resection reduce the need for discharge to skilled care facility?

BACKGROUND

A significant proportion of patients, especially the elderly undergoing colon resections, are likely to be discharged to a skilled care facility. This study aims to examine whether the technique of colectomy, open versus laparoscopic, contributed to their discharge to a skilled care facility.

METHODS

This was a retrospective analysis using discharge data from the Nationwide Inpatient Sample (NIS), Healthcare Cost and Utilization Project, Agency for Healthcare Research and Quality. Adult patients who underwent colectomy in 2009 were evaluated. SAS and SUDAAN software were used to provide weighted estimates and to account for the complex sampling design of the NIS. We compared routine discharge to nonroutine discharge, defined as transfer to short-term hospital, skilled nursing facility, intermediate care, home health, or another type of facility.

RESULTS

A weighted total of 221,294 adult patients underwent colectomy in 2009 and had the primary outcome of discharge available. Of these colon resections, 70,361 (32 %) were performed laparoscopically and 150,933 (68 %) by open technique. A total of 139,047 (62.8 %) patients had routine discharge and 73,572 (33.3 %) nonroutine. A total of 8,445 (3.8 %) patients died while in the hospital, and 229 (0.1 %) left against medical advice and were excluded from further analysis. On univariate analysis, age ≥ 65 years, female gender, Black/Hispanic race, open technique (compared to laparoscopic), Medicare/Medicaid insurance status, comorbidity index of ≥ 1, and malignant primary diagnosis predicted nonroutine discharge. A multivariate logistic model was then used to predict nonroutine discharge in these patients using variables significant in the univariate analysis at the α = 0.05 significance level. In the multivariate analysis, open compared to laparoscopic technique was independently associated with increased likelihood of discharge to skilled care facilities (odds ratio 2.85, 95 % confidence interval 2.59-3.14).

CONCLUSIONS

In addition to the expected factors like advancing age, female gender, and increasing comorbidity index, open compared to laparoscopic technique for colectomy is associated with an increased likelihood of discharge to skilled care facilities. When feasible, the laparoscopic technique should be considered as an option, especially in the elderly patients who require colon resection, because it may reduce their likelihood of discharge to a skilled care facility.
