The long-term outcome after treatment for patients with tibial fracture treated with intramedullary nailing is not influenced by time of day of surgery and surgeon experience

After-hour elective total knee arthroplasty does not affect clinical outcomes but negatively affects alignment

INTRODUCTION

In cases of limited medical resources, elective total knee arthroplasty (TKA) sometimes needs to be performed after typical work hours. However, surgeon fatigue and logistical factors may potentially affect outcomes. This study aimed to detect whether after-hour procedures impair outcomes after TKA.

MATERIALS AND METHODS

Elective unilateral TKA from Jan 1, 2016 to Nov 31, 2018 was retrospectively selected and separated into two groups. Procedures started from 8:00 A.M. to 5:29 P.M. were identified as day-time surgeries, whereas those started from 5:30 P.M. to 11:59 P.M. were considered after-hour surgeries. Operative period, Knee Society Score (KSS), range of motion (ROM), total blood loss, length of hospital stay (LOS), and postoperative adverse events and complications were compared. Additionally, the components were evaluated radiologically.

RESULTS

A total of 321 patients were selected, including 258 (80.37%) patients in the day-time group and 63 (19.63%) patients in the after-hour group. Operative period, LOS, total blood loss were similar between groups. The overall and each specific incidence of postoperative complications were comparable between the two groups, but the incidence of postoperative vomiting (POV) was higher in the after-hour group. There was no significant difference in knee joint function as shown by the KSS and ROM, both on the 3rd day and at 2 years after surgeries. Radiologically, there were no significant differences between the two groups in the femoral notches (P = 0.592). However, better coronal alignment was detected in the day-time group (P = 0.002), consistent with which there were less outliers (P = 0.033).

CONCLUSION

After-hour TKA procedure does not exert an impact on clinical outcomes, but negatively affects lower limb alignment. Besides, after-hour TKA surgery impairs patients' comfort by increasing POV.

Effect of Surgeon Experience on Long-Term Patient Outcomes in Surgical Repair of Acute Achilles Tendon Rupture

Background:

The effect of surgeon experience on patient outcomes after surgical Achilles tendon rupture (ATR) repair has so far been unknown.

Purpose:

To examine whether patient-reported and functional outcomes as well as adverse events after surgical ATR repair differ between orthopaedic specialist surgeons and resident surgeons.

Study Design:

Cohort study; Level of evidence, 3.

Methods:

We retrospectively analyzed data from 295 patients treated with surgical ATR repair with standardized techniques. The level of surgeon experience (specialist vs resident) and number of adverse events (rerupture, infection, and deep venous thrombosis) were recorded. Patient-reported and functional outcomes were assessed 12 months postoperatively using the validated Achilles tendon total rupture score (ATRS) and the heel-rise test, respectively. Analysis of covariance was used to compare differences in outcomes between specialist surgeons and resident surgeons. Pearson chi-square or Fisher exact test was used for analysis of adverse events.

Results:

The mean ATRS at 12 months for patients operated on by resident surgeons was significantly higher compared with specialist surgeons (85.9 [95% CI, 80.3-91.5] vs 77.8 [95% CI, 73.8-81.9]; P = .028). In addition, the lateral difference (operated vs unoperated side) in mean total concentric work and number of heel-rise repetitions at 12 months was smaller in patients operated on by resident surgeons (P = .011 and 0.015, respectively). The number of adverse events did not differ significantly between the 2 groups.

Conclusion:

Resident surgeons achieved patient-reported and functional outcomes at least as good as those of specialist surgeons in surgical ATR repair, with a similar risk of adverse events.

Adult spinal deformity surgery: the effect of surgical start time on patient outcomes and cost of care

PURPOSE

There are reports investigating the effect of surgical start time (SST) on outcomes, length of stay (LOS) and cost in various surgical disciplines. However, this has not been studied in spine deformity surgery to date. This study compares outcomes for patients undergoing spinal deformity surgery based on SST.

METHODS

Patients at a single academic institution from 2008 to 2016 undergoing elective spinal deformity surgery (defined as fusing ≥ 7 segments) were divided by SST before or after 2 PM. Co-primary outcomes were LOS and direct costs. Secondary outcomes included delayed extubation, ICU stay, complications, reoperation, non-home discharge, and readmission rates.

RESULTS

There were 373 surgeries starting before 2 PM and 79 after 2 PM. The cohorts had similar demographics including age, sex, comorbidity burden, and levels fused. The late SST cohort had shorter operation durations (p = 0.0007). Multivariable linear regression showed no differences in LOS (estimate 0.4 days, CI - 1.2 to 2.0, p = 0.64) or direct cost (estimate $3652, 95% CI - $1449 to $8755, p = 0.16). Multivariable logistic regression revealed the late SST cohort was more likely to have delayed extubation (OR 2.6, 95% CI 1.4-4.9, p = 0.004) and non-home discharge (OR 2.2, 95% CI 1.1-4.2, p = 0.03). All other secondary outcomes were non-significant.

CONCLUSION

Patients undergoing spinal deformity surgery before and after 2 PM have similar LOS and cost of care. However, the late SST cohort had increased likelihood of delayed extubation and non-home discharges, which increase cost in bundled payment models. These findings can be utilized in OR scheduling to optimize outcomes and minimize cost.

Scheduled Emergency Trauma Operation: The Green Line Orthopedic Trauma Surgery Process Of Care

BACKGROUND AND AIMS

Traditionally, patients requiring an orthopedic emergency operation were admitted to an inpatient ward to await surgery. This often led to congestion of wards and operation rooms while, for less urgent traumas, the time spent waiting for the operation often became unacceptably long. The purpose of this study was to evaluate the flow of patients coded green in a traffic light-based coding process aimed at decreasing the burden on wards and enabling a scheduled emergency operation in Central Finland Hospital.

MATERIALS AND METHODS

Operation urgency was divided into three categories: green (>48 h), yellow (8-48 h), and red (<8 h). Patients, who had sustained an orthopedic trauma requiring surgery, but not inpatient care (green), were assigned an operation via green line process. They were discharged until the operation, which was scheduled to take place during office hours.

RESULTS

Between January 2010 and April 2015, 1830 green line process operations and 5838 inpatient emergency operations were performed. The most common green line process diagnoses were distal radial fracture (15.4% of green line process), (postoperative) complications (7.7%), and finger fractures (4.9%). The most common inpatient emergency operation diagnosis was hip fracture (24.3%). Green line process and inpatient emergency operation patients differed in age, physical status, diagnoses, and surgical procedures.

CONCLUSION

The system was found to be a safe and effective method of implementing orthopedic trauma care. It has the potential to release operation room time for more urgent surgery, shorten the time spent in hospital, and reduce the need to operate outside normal office hours.

Rate of Open Reduction for Supracondylar Humerus Fractures Varies Across Pediatric Orthopaedic Surgeons: A Single-Institution Analysis

OBJECTIVES

To (1) define a single institution's rate of open reduction for operative pediatric supracondylar humerus (SCH) fractures; (2) describe variability by surgeon in rates of irreducible fracture (IRF) and open reduction; and (3) determine whether variation in opening rate correlated with surgeon experience.

DESIGN

Retrospective analytic study.

SETTING

Urban tertiary care Level 1 trauma center.

PATIENTS/PARTICIPANTS

Twelve fellowship-trained pediatric orthopaedists.

MAIN OUTCOME MEASUREMENTS

Rate of open reduction for operatively treated SCH fractures (OTA/AO 13-M/3).

RESULTS

One thousand two hundred twenty-nine type II SCH fractures (none of which required open reduction) were excluded from the analysis. A total of 1365 other SCH fractures were included: 1302 type III fractures, 27 type IV fractures, and 36 fractures with unspecified type. 2.9% of type III and 22.2% of type IV fractures required open reduction. None of the injuries with unspecified type required open reduction. The rate of open reduction among 11 surgeons ranged from 0% to 15.0% in type III-IV fractures (P = 0.001). 86% (38/44) of open reductions were performed for IRF. In regression analysis, patient age was associated with open reduction for IRF (odds ratio 1.22, P = 0.001), but surgeon years-in-practice (0.321) and number of previous cases (0.327) were not associated with open reduction. Other indications for opening included suspected vascular or neurologic injury.

CONCLUSIONS

Open reduction was rarely performed in this sample, but IRF was the dominant indication for opening. We found true variation in surgeons' rates of performing open reductions. More experience was not correlated with decreased likelihood of open reduction.
