Effect of weekend admission on geriatric hip fractures

"Off-Hour" Surgical Start Times Do Not Influence Surgical Precision and Outcomes in Middle-aged Patients and Patients 65 Years and Older With Hip Fractures

BACKGROUND

Previous studies show the "off-hour" effect impacts outcomes after surgery in non-orthopedic settings. This study assessed if the off-hour effect impacts surgical precision and outcomes in middle-aged patients and patients 65 years and older with hip fractures.

MATERIALS AND METHODS

All operative patients in an academic medical center's institutional review board-approved hip fracture registry were reviewed for demographics, hospital quality measures, operative details, radiographic parameters, and outcomes. Patients were grouped into standard (7 am to 4:59 pm) and off-hour (5 pm to 6:59 am) cohorts depending on surgical start time and comparative analyses were conducted. Two subanalyses were conducted: one comparing the quality of reduction for patients with intertrochanteric hip fractures and another comparing the rates of inpatient transfusion and postoperative dislocation for patients treated with arthroplasty.

RESULTS

A total of 2334 patients underwent operative treatment. The off-hour cohort had hospital quality measures and outcomes similar to the standard cohort, including length of stay, rates of inpatient complication, mortality, and readmission. Sub-analysis of 814 intertrochanteric hip fractures demonstrated similar tip-apex distance, residual calcar step-off, and post-fixation neck-shaft angle, while subanalysis of 713 patients undergoing arthroplasty showed similar rates of transfusion and dislocation between cohorts.

CONCLUSION

The time of day patients undergo hip fracture repair does not affect surgical outcomes or hospital quality measures. These results highlight the need for standardized hip protocols and treatment pathways to provide equitable care at all hours of the day. [Orthopedics. 2024;47(3):185-191.].

The impact of holiday season and weekend effect on traumatic injury mortality: Evidence from a 10-year analysis

Objectives

Trauma is one of the leading causes of death and its incidence increases annually. The "weekend effect" and "holiday season effect" on traumatic injury mortality remain controversial, whereby traumatic injury patients admitted during weekends and/or holiday season have a higher risk of in-hospital death. The present study is aimed to explore the association between "weekend effect" and "holiday season effect" and mortality in traumatic injury population.

Materials and Methods

This retrospective descriptive study included patients from the Taipei Tzu Chi Hospital Trauma Database between January 2009 and June 2019. The exclusion criterion was age of < 20 years. The primary outcome was the in-hospital mortality rate. The secondary outcomes included intensive care unit (ICU) admission, ICU re-admission, length of stay (LOS) in the ICU, ICU admission duration ≥ 14 days, total hospital LOS, total hospital LOS ≥ 14 days, need for surgery, and re-operation rate.

Results

In this study, 11,946 patients were included in the analysis, and 8143 (68.2%) patients were admitted on weekdays, 3050 (25.5%) on weekends, and 753 (6.3%) on holidays. Multivariable logistic regression revealed that the admission day was not associated with an increased risk of in-hospital mortality. In other clinical outcome analyses, we found no significant increase in the risk of in-hospital mortality, ICU admission, ICU LOS ≥ 14 days, or total LOS ≥ 14 days in the weekend and holiday season groups. The subgroup analysis showed that the association between holiday season admission and in-hospital mortality was noted only in the elderly and shock condition populations. The holiday season duration did not differ in terms of in-hospital mortality. Longer holiday season duration was also not associated with an increased risk of in-hospital mortality, ICU LOS ≥14 days, and total LOS ≥14 days.

Conclusion

In this study, we did not find any evidence that weekend and holiday season admissions in the traumatic injury population were associated with an increased risk of mortality. In other clinical outcome analyses, there was no significant increase in the risk of in-hospital mortality, ICU admission, ICU LOS ≥ 14 days, or total LOS ≥ 14 days in the weekend and holiday season groups.

Identification of preoperative factors and postoperative outcomes in relation to delays in surgery for hip fractures

We evaluated factors and outcomes associated with elapsed time to surgery (ETTS) in 1,081 men and 2,891 women (mean age 83.5 years ±9.1) undergoing hip fracture surgery (from 2009-2019). Mortality rates were 4.8%, 6.3%, 6.2% and 10.3% (chi-squared 19.0; p<0.001), and hospital length of stay (LOS) >19 days were 31.9%, 32.8%, 33.8% and 43.2% (chi-squared 18.5; p<0.001) for ETTS <24 hours, 24-35 hours, 36-47 hours and ≥48 hours, respectively. There were no differences between ETTS categories for failure to mobilise within 1 day of surgery, pressure ulcers or discharge to nursing care. After adjustment for age, sex, American Society of Anesthesiologists' score and years of data collection, compared with Sunday, the risk of ETTS ≥36 hours was highest on Friday (odds ratio (OR) 3.50; 95% confidence interval (CI) 2.43-5.03) and Saturday (OR 4.70; 95% CI 3.26-6.76). Compared with ETTS <24 hours, there were increases in the risk of death when ETTS ≥48 hours (OR 2.31; 95% CI 1.47-3.65) and LOS >19 days (OR 1.34; 95% CI 1.02-1.75). The median (interquartile range (IQR)) LOS for ETTS <24 hours was 12.7 days (IQR 8.0-23.0), 24-35 hours was 13.5 days (IQR 8.4-22.9), 36-47 hours was 14.1 days (IQR 8.9-23.3) and ≥48 hours was 16.9 (IQR 10.8-27.0; p<0.001). The 10-year period of collection did not change the conclusion. Admissions towards the end of the week are associated with delayed ETTS for hip fractures, while delay in surgery, particularly beyond 48 hours, is associated with increased risk of mortality and prolonged LOS.

Orthopaedic trauma on the weekend: Longer surgical wait times, and increased after-hours surgery

INTRODUCTION

Orthopaedic trauma does not present in a linear fashion. Fluctuations in trauma volumes, after-hours surgery and surgical wait times impact orthopaedic surgeons and patients. There is little research focussing on how surgical trauma volumes change throughout the week. This study investigated the relationship between day of the week and surgical orthopaedic trauma volumes, after-hours surgery, and wait times for orthopaedic trauma patients.

METHODS

All unscheduled surgical orthopaedic trauma cases presenting to one level I and three level IV urban adult trauma centers between 2008 and 2018 were retrospectively reviewed. Fluctuations in orthopaedic trauma volumes and amount of after-hours surgeries completed were investigated using Multivariable Poisson regression. Fluctuations in patient wait times were investigated using linear regression.

RESULTS

Weekends were associated with increased surgical wait times (8.9%, p<0.001) despite decreased surgical trauma volumes (9.1%, p<0.001). Surgical orthopaedic trauma volumes were elevated on weekdays and decreased on weekends. More after-hours surgeries were performed from Thursday to Saturday with most performed on Friday night (26.6%, p<0.001). Surgical wait times increased midweek and remained high until Saturday.

CONCLUSION

With a lack of dedicated trauma resources on the weekend, a significant increase in after-hours surgery and surgical wait times was identified following surgical volumes peaking on Thursday and Friday. We suggest adapting resource allocation to reflect surgical volumes. Dedicated weekend orthopaedic trauma resources or an adaptable schedule during increased orthopaedic trauma have the potential to ease this bottleneck, improve patient care, and decrease hospital costs.

Access to care for low trauma hip fractures in South Africa

RATIONALE

Early surgery is recommended for hip fractures.

MAIN RESULT

In this study only one-third of subjects with hip fractures were admitted within 24 h of the fracture, and surgery was delayed beyond 48 h in the majority.

SIGNIFICANCE

These findings highlight the need to improve access to care for hip fracture subjects.

PURPOSE

There is limited data on the timing of admission and surgery following a low trauma hip fracture (HF) in South Africa (SA).

METHODS

A prospective, observational study was conducted at public and private hospitals in three provinces, Gauteng (GP), KwaZulu-Natal (KZN) and the Western Cape (WC), in SA to determine time from fracture to admission and from admission to surgery in patients presenting with low trauma HF. Associations with delayed admission and surgery were explored using logistic regression.

RESULTS

The median age of the 1996 subjects was 73 years (IQR 63-81 years), the majority were women (1346, 67%) and 1347 (67%) were admitted to the public hospitals. In one-third of subjects (661, 33%), admission was delayed to beyond 24 h after the fracture. There was a significantly longer time to admission in public compared to private hospitals (21 h [IQR 10.0-48.5] versus 6 h [IQR 3.3-14.1], p < 0.001), in subjects < 65 years, the WC and when admission occurred on a weekday. Surgery was delayed beyond 48 h in the majority (1272, 69%) of subjects and was significantly longer in public compared to private hospitals (130 h [IQR 62.6-212.4] versus 45.4 h [IQR 24.0-75.5], p < 0.001), in KZN, and when admission occurred after hours.

CONCLUSION

The burden of HFs is higher at public hospitals in SA, where there is a significant delay in admission after a fracture and surgery after admission. This highlights the need for a review of HF care pathways, resources and policies.
