Mortality after proximal femur fracture with a delay of surgery of more than 48 h

Timing of Noncardiac Surgery Following Transcatheter Aortic Valve Replacement: A National Analysis

BACKGROUND

The optimal timing of noncardiac surgery (NCS) following transcatheter aortic valve replacement (TAVR) for aortic stenosis has not been elucidated by current national guidelines.

OBJECTIVES

The aim of this study was to evaluate the effect of the time interval between TAVR and NCS (Δt) on the perioperative risk of major adverse events (MAEs).

METHODS

All adult admissions for isolated TAVR for aortic stenosis were identified in the 2016 to 2020 Nationwide Readmissions Database. Patients who received NCS on subsequent admission were included for analysis and grouped by Δt as follows: ≤30, 31 to 60, 61 to 90, and >90 days. Multivariable regression models were constructed to examine the association of Δt with ensuing outcomes.

RESULTS

Of 3,098 patients (median age = 79 years, 41.6% female), 19.1% underwent NCS at ≤30 days, 22.9% at 31 to 60 days, 16.7% at 61 to 90 days, and 41.3% at >90 days. After adjustment, the odds of MAEs were similar for operations performed at ≤30 days (adjusted OR [AOR]: 1.05; 95% CI: 0.74-1.50), 31 to 60 days (AOR: 0.97; 95% CI: 0.71-1.31), and 61 to 90 days (AOR: 0.95; 95% CI: 0.67-1.34), with those at >90 days as reference. When examining the average marginal effect of the interval to surgery, risk-adjusted MAE rates were statistically similar across Δt groups for elective status and NCS risk category combinations.

CONCLUSIONS

NCS within 30, 31 to 60, or 61 to 90 days after TAVR was not associated with increased odds of MAEs compared with operations after 90 days irrespective of NCS risk category or elective status. Our findings suggest that the interval between NCS and TAVR may not be an accurate predictor of MAE risk in this population.

Prevalence and Clinical Outcomes of Noncardiac Surgery After Transcatheter Aortic Valve Replacement

Aortic stenosis is a prevalent valvular heart disease, especially in the older people. They often coexist with other co-morbidities, and noncardiac surgery carries a higher risk because of the underlying valve condition. Despite the growing concern about the safety and optimal management of noncardiac surgery post-transcatheter aortic valve replacement (TAVR), there is limited evidence on this matter. This study aims to assess the clinical outcomes of noncardiac surgeries after TAVR. This retrospective study included 718 patients who underwent TAVR. Of these, 36 patients underwent noncardiac surgery after TAVR. The primary end point was the incidence of cardiovascular adverse events post-TAVR and the secondary end point was the incidence of structural valve deterioration. Composite end points included disabling stroke, heart failure requiring hospitalization, and cardiac death as defined by Valve Academic Research Consortium 3. Most of these surgeries were orthopedic and classified as intermediate risk. All noncardiac surgeries were performed without perioperative adverse events. There was no observed structural valve deterioration, and the incidence of composite end points did not significantly differ between the surgical and nonsurgical groups during the follow-up period. Noncardiac surgery after TAVR can be performed safely and does not have a negative impact on prognosis. Further studies are warranted to determine the optimal strategy for noncardiac surgery after TAVR.

[Influence of timing of surgery on complication rates after cemented hemiarthroplasty for treatment of medial femoral neck fractures]

BACKGROUND

The optimal timing of the implantation of a cemented hemiarthroplasty in the management of displaced medial femoral neck fractures is still the subject of current research. According to the current recommendations, these cases should be surgically treated within 24 h. The aim of this study was to evaluate the impact of the timing of surgery on operation-specific and nonspecific complications, intensive care treatment as well as mortality.

MATERIAL AND METHODS

Overall, 152 cases were retrospectively investigated regarding several parameters (demographic data, comorbidities, surgery time, duration of hospital stay, intensive care treatment, general, bleeding, operation-specific and nonspecific complications). The statistical analysis was performed using the χ²-test and the unpaired Student's t‑test as well as logistic regression analyses.

RESULTS

A total of 152 patients were included and 71.1% of the operations were performed within 24 h and the remaining 28.9% after 24 h. All groups showed a similar profile of comorbidities. The analysis of the intensive care treatment showed no significant differences between the individual groups. The rate of postoperative pneumonia was moderately higher among the patients with a procedure after 24 h; however, with no severe courses. There were no significant differences regarding all other complications and the mortality rate between the individual time points of surgery.

CONCLUSION

The present study demonstrated that patients operated on after 24 h showed no disadvantages regarding other complications, intensive care treatment or mortality, except from an increased postoperative pneumonia rate. These results could be taken into consideration for the next update of the treatment guidelines.

[Changes in the patient population with proximal femur fractures over the last decade : Incidence, age, comorbidities, and length of stay]

BACKGROUND

Over the last decade, the percentage of people >65 years has increased from 16.6% to 20.7%. In industrialized countries, the annual incidence in people >65 years with a proximal femur fracture is about 600-900 per 100,000 population. The incidence will increase by 3-5% per year. Guidelines advocate early surgery as soon as possible but within 24 h. External quality control requires surgical treatment within 48 h. In this study, the changes in the patient population with proximal femur fractures and their treatment during the last decade were investigated.

METHODS

From 2005-2014, data of all patients ≥65 years with proximal femur fractures were recorded. The patients were treated in a level 1 trauma center certified by the German Society for Trauma Surgery. The evaluation was carried out by means of descriptive statistics.

RESULTS

In all, 2093 patients with proximal femur fractures (1164 trochanteric neck fractures and 929 femoral neck fractures) were evaluated. The annual increase in the percentage of patients was 1.5-2%. Over the decade, the percentage of patients increased by 20% and the average age increased by 2 years. There were no changes in comorbidities or case mix index during the investigation period. Despite the increase of the preoperative waiting times, a decrease in the total length of stay was found.

DISCUSSION

The increase in the number of patients, as well as the requirements of the guidelines and external quality control are relevant challenges for the hospitals. More human and material resources (e. g., surgical capacity) are needed. The increase in the age of the patients, their comorbidities, and medication must be taken into account, e. g., in the context of geriatric orthopedic trauma centers.

[Elderly trauma patients with proximal femur fractures : Statistical evaluation of regular process data from a trauma center for the elderly]

BACKGROUND/AIMS

Proximal femoral fractures are one of the most frequently occurring injuries among elderly people. High rates of inpatient treatment indicate the importance of optimized clinical care.

OBJECTIVES

Based on selected outcome parameters in elderly trauma patients with proximal femoral fractures, the current situation of medical care in a trauma center for geriatric patients is presented.

METHODS

For a descriptive evaluation of outcome parameters, 250 patients aged 70 years and older have been included. A clinical register of a trauma center for the elderly served as the database.

RESULTS

The average length of stay was approximately 25 days. Sixty-seven percent of the patients underwent surgical treatment within 24 h of admission to the hospital. More than half of the patients were taking anticoagulant drugs. Around 18 % of patients presented with one or more complications. Mortality rate was 5.2 %. Thirty-two percent of those patients who had been living at home before admission had been discharged to a nursing home.

DISCUSSION AND CONCLUSIONS

Analyzing the data of a trauma registry enables critical reflection upon the clinical outcome of interdisciplinary treatment procedures. The low rate of mortality may be a result of the geriatric co-treatment, starting right from admission. It remains unclear whether the influence of preoperative interdisciplinary treatment outweighs the effect of a timely surgical procedure.

Timing of surgery for hip fractures in the elderly: A retrospective cohort study

INTRODUCTION

Although early surgery for elderly patients with hip fracture is recommended in existing clinical guidelines, the results of previous studies are inconsistent. The aim of this study was to compare postoperative outcomes of early and delayed surgery for elderly patients with hip fracture.

MATERIALS AND METHODS

In this retrospective study using a national inpatient database in Japan, patients aged 65 years or older who underwent surgery for hip fracture between July 2010 and March 2014 were included. Early surgery was defined as surgery on the day or the next day of admission. Assessed outcomes included death within 30 days and hospital-acquired pneumonia.

RESULTS

In this cohort, 47,073 (22.5%) patients underwent surgery for hip fractures within two days of admission (early surgery group) and 161,805 (77.5%) underwent surgery for hip fractures thereafter (delayed surgery group). Early surgery was significantly associated with lower odds for hospital-acquired pneumonia (odds ratio, 0.42; 95% confidence interval, 0.25-0.69) and pressure ulcers (odds ratio, 0.56, 95%CI: 0.33-0.96, p = 0.035), but was not associated with 30-day mortality (odds ratio, 0.96; 95% confidence interval, 0.49-1.86) or pulmonary embolism (odds ratio, 1.62, 95%CI: 0.58-4.52, p = 0.357).

CONCLUSIONS

These results support current guidelines, which recommend early surgery for elderly hip fractures patients.

Factors Affecting Mortality and Hospital Admissions after Hip Surgery among Elderly Patients with Hip Fracture in Hong Kong - Review of a Three-Year Follow-Up. Hong Kong J Occup Ther 2017;30:6-13. [PMID: 30186075 PMCID: PMC6092006 DOI: 10.1016/j.hkjot.2017.10.004]

Objective

Hip fracture is associated with excess mortalities and high rate of hospital re-admission after discharge from the indexed episode. To improve related post-discharge care, we aimed to find out characteristics that were associated with related higher rates of mortality and hospital re-admission.

Methods

This was a historical cohort study with following up of 273 patients recruited in a local rehabilitation hospital for 3 years. The outcome of interest was cumulative mortalities and hospital re-admissions in the 1st 3 years after their discharge from the rehabilitation hospital. These outcomes were collected in the hospital data warehouse - the Clinical Data Analysis and Reporting System (CDARS). Eighteen predictors, as proposed by similar studies and our own review, were retrieved from our standard clinical forms as well as from the CDARS. Binary logistic regression was used to test their association with the outcomes and to generate the respective odd ratios.

Results

The cumulative overall mortality rates at 0.5-, 1-, 2- and 3- year after hip fracture were 7.2%, 14.0%, 24.6% and 33.4% respectively, while the cumulative "1st ever hospital read-mission" at 0.5-, 1, 2- and 3- years after hip fracture were 29.4%, 41.6%, 59.4% and 71.7% respectively. The most significant predictors i) for mortality at 3- year were: "Being male" (OR 5.33), "Delayed surgery >48 hours" (OR 2.65), "pre-operation albumin level <3.5 g/dl" (OR 2.66), and, ii) for "1st ever hospital readmission" at 0.5-year was "Being Assisted walker or non-walker (after rehabilitation)" (OR 3.83).

Conclusions

Characteristics that define the groups of patients with hip fractures with higher mortality and rate of hospital re-admission were identified. This could help healthcare professionals to focus on target patient groups for closer monitoring and more intensive post-discharge care.

[Length of hospital stay for patients with proximal femoral fractures : Influencing factors]

BACKGROUND

In departments of orthopedic and trauma surgery patients with proximal femoral fractures constitute the largest proportion of trauma patients. The length of stay (LOS) has economic consequences and prolonged LOS leads to a shortage in bed capacity.

OBJECTIVES

In this study treatment and patient-related factors that influence the LOS of patients with proximal femoral fractures were investigated.

MATERIAL AND METHODS

Treatment and patient-related data of 242 patients (age >64 years) were recorded retrospectively and included residential aspects, legal guardianship, time of admission and surgery, hospital mortality, LOS, diagnosis, comorbidities, medication, surgical treatment, general and surgical complications, intensive care therapy and American Society of Anesthesiologists (ASA) classification.

RESULTS

Of the patients, one fifth came from a nursing home and were under supervised care or a healthcare proxy at the time of admission. Two thirds were admitted to hospital and operated on during on-call service periods. One half of the patients did not return to their previous domestic environment and were usually admitted to a nursing home. Patients who came from or were admitted to nursing homes, who were under healthcare supervision as well as patients who rapidly underwent surgery had a shorter LOS. Hospitalization and surgery during on-call service periods did not extend the LOS and showed a tendency towards reduction. Older age correlated with a longer LOS and surgical complications doubled the LOS.

DISCUSSION

Surgical treatment during on-call service periods, short preoperative waiting times and avoidance of surgical complications shortened LOS and thus had an impact on costs and bed capacity.

[Factors influencing course of hospitalization in patients with hip fractures: Complications, length of stay and hospital mortality]

BACKGROUND

Time of surgery, age, sex, and co-morbidities influence the complication and mortality rate in patients with hip fractures. Patients with relevant co-morbidities, who were hospitalized at the weekend have a higher mortality rate. Complications prolong length of stay (LOS), which results in higher costs and shortage of bed capacity.

OBJECTIVES

The influence of various factors on hospitalization with emphasis on complications, LOS, and clinical mortality should be observed.

MATERIALS AND METHODS

Retrospectively, 242 patients with hip fractures (>64a) were observed. In addition to age and sex, time of hospitalization and surgery, intensive care therapy, hospital mortality, LOS, comorbidities, ASA, and complications were recorded. Times were assigned to the work week or the weekend or regular or on-call duty service.

RESULTS

29.8 % were hospitalized at the weekend, 66.1% on on-call duty, 24.1% were operated on the weekend, 67.4% on on-call duty. 86.3% were operated <48 h after admission. The mortality rate was 8.3%. Longer time to surgery results in more frequent intensive care therapy, prolongs the LOS, and increases overall complications. Advanced age increases mortality and LOS. A higher value of the ASA classification leads to increased mortality; co-morbidities lead to more frequent intensive care therapy. Surgical complications prolong LOS of 10.8d (86.4%).

CONCLUSION

Hospitalization is influenced by age, ASA and co-morbidities as well as by time to surgery and operation in day or late and nighttime service. Early surgery and prevention of surgical complications reduce LOS.

Factors Associated With Early Functional Outcome After Hip Fracture Surgery

Background:

Hip fractures are common in the elderly and are likely to become more prevalent as the US population ages. Early functional status is an indicator of longer term outcome, yet in-hospital predictors of functional recovery, particularly time of surgery and composition of support staff, after hip fracture surgery have not been well studied.

Methods:

Ninety-nine consecutive patients underwent hip fracture surgery by a single surgeon between 2009 and 2013. Surgery after 48 hours was deemed as surgical delay, and surgery after 5 pm was deemed as after hours. Surgical support staff experience was determined by experts from our institution as well as documented level of training. Functional status was determined by independent ambulation on postoperative day (POD) 3.

Results:

On POD3, 48 (79%) of 62 patients with no delay were able to ambulate, whereas only 14 (38%) of 37 patients with delayed surgery were able to ambulate (P < .001). This relationship persisted when adjusted for American Society of Anesthesiologist classification. No delay in patients older than 80 (odds ratio [OR], 6.91; 95% confidence interval [CI], 2.16-22.10) and females (OR, 7.05; 95% CI, 2.34-21.20) was associated with greater chance of early ambulation. After-hours surgery was not associated with ambulation (P = .35). Anesthesiologist and circulating nurse experience had no impact on patient’s ambulatory status; however, nonorthopedic scrub technicians were associated with worse functional status (OR 7.50; 95% CI, 1.46-38.44, P = .01).

Conclusion:

Surgical delay and nonorthopedic scrub technicians are associated with worse early functional outcome after hip fracture surgery. Surgical delay should be avoided in older patients and women. More work should be done to understand the impact of surgical team composition on outcome.
