Providing perioperative care for patients with hip fractures

An In-Depth Analysis of Providers and Services of Cancellation in Anesthesia Reveals a Complex Picture after Systemic Analysis

The variances in operating room (OR) cancellation rates between different service lines and operators within these service lines were assessed by reviewing the electronic medical record (EMR) covering 34,561 cases performed by 199 OR operators in 2018. We assumed that cancellations would differ between different service lines, but the between-operators variance was minimal within the service line. We hypothesized that most variability would be secondary to patient-specific (weekdays, time of year, and national holidays), seasonal and administrative issues. Of 4165 case cancellations, the majority (73.1%) occurred before the patient arrived at the hospital. A total of 60% of all cancellations were within gastroenterology, interventional cardiology, and orthopedics. Cancellation rate variability between surgeons operating within the same service line greatly varied between services from very homogenous to very diverse across providers. The top reasons for cancellation were: date change, canceled by a patient, or "no show". The highest cancellation rates occurred on Mondays and Tuesdays, in January and September, and during weeks associated with national holidays. In summary, cancellation variability must be analyzed at the level of individual specialties, operators, and time variability.

Preoperative risk factors for postoperative pneumonia following primary Total Hip and Knee Arthroplasty

BACKGROUND

The purpose of this study is to evaluate risk factors for pneumonia following THA and TKA.

METHODS

Patients were identified from the American College of Surgeons National Quality Improvement Database (NSQIP) who experienced postoperative pneumonia after undergoing primary THA and TKA.

RESULTS

Many characteristics including old age, anemia, diabetes, cardiac comorbidities, dialysis, and smoking were independent risk factors for postoperative pneumonia after THA or TKA.

CONCLUSION

This analysis offers new evidence on risk factors associated with the development of pneumonia after THA and TKA. These risk factors can help guide clinicians in preventing postoperative pneumonia after THA and TKA.

The impact of antithrombotic therapy on surgical delay and 2-year mortality in older patients with hip fracture: a prospective observational study

PURPOSE

To analyze the associations of oral anticoagulant and antiplatelet treatments in older patients requiring surgical treatment for hip fracture with mortality, length of stay, waiting time to surgery and postsurgical immediate complications.

METHODS

A prospective observational study, including surgically treated hip fracture patients aged 65 years and older. We analyzed admission status variables, and time to surgery, length of stay and immediate surgical and medical complications. We recorded a 2-year survival follow-up.

RESULTS

Of the 237 patients studied, 32.5% received antiplatelet treatment and 17.7% received oral anticoagulant treatment. The overall 2-year mortality was 29.1%. The 2-year mortality rate reached the 33.8% for antiplatelet-treated patients (n.s.) and 45.2% for oral anticoagulated patients (p = 0.011). The length of stay increased significantly associated with the oral anticoagulant or high-dose antiplatelet treatment (p < 0.001). The same happened for the time to surgery (p < 0.001), but no delay was observed for patients with low-dose antiplatelet treatment. Oral anticoagulated and antiplatelet-treated patients had a higher Charlson comorbidity index (p = 0.004, p = 0.019) and ASA score (p = 0.006, p = 0.011). Those treatments were also associated with a higher rate of some immediate postsurgical medical complications. We found a relationship between low hemoglobin at admission and high-dose antiplatelet treatment (p = 0.044).

CONCLUSIONS

Hip fracture patients following previous oral anticoagulant treatment have a higher 2-year mortality rate. The oral anticoagulant or high-dose antiplatelet treatments are significantly associated with an increase in the length of stay, related to time to surgery, but we could not demonstrate an effect on early mortality.

Goldman score, but not Detsky or Lee indices, predicts mortality 6 months after hip fracture

Background

Over the past years, several cardiac risk indices were evaluated and modified, including Goldman, Detsky, and Lee scores. The predictive capacity of these scores in hip fracture patients is lacking. Thus, our objective was to compare the Goldman, Detsky, and Lee scores as predictors of mortality in 6 months after hip fracture.

Methods

We prospectively evaluated 80 consecutive patients with hip fractures, over the age of 65 admitted to an orthopedic ward at Botucatu Medical School. Patient demographic information, Goldman, Detsky and Lee scores were recorded. All patients were followed for 6 months after hip fracture, and mortality was recorded. Multiple logistic regression analyses were performed for mortality prediction.

Results

The mortality rate was 23% after a 6-month follow-up period. Patients who died had advanced age and the majority of them were male. They also had lower values of handgrip strength, and higher values of creatinine and urea. In the multiple logistic regression models when adjusted by age, gender, handgrip strength and creatinine, Goldman’s score (OR:3.025; 95%CI:1.022-8.953; p:0.046), but not Detsky (OR:2.328; 95%CI:0.422-12.835; p:0.332) and Lee (OR:1.262; 95%CI:0.649-2.454; p:0.494), was associated with mortality 6 months after hip fracture. Each 1 category increase in Goldman score increased the mortality to more than 3-fold.

Conclusions

In conclusion, our data suggest that Goldman score, but not Detsky or Lee indices, predicts mortality associated with hip fracture at up to 6 months post-injury.

Clinical characteristics and risk factors of postoperative pneumonia after hip fracture surgery: a prospective cohort study

In this study, we attempt to determine the clinical characteristic and risk factors of postoperative pneumonia (POP) after hip fracture surgery in a well-defined hip fracture cohort. We find that intrinsic factors as well as major clinical interventions were all important risk factors of POP.

INTRODUCTION

Postoperative pneumonia (POP) is one of the major complications following hip fractures surgery. However, the risk factors of POP are not well studied in hip fracture cohorts. We attempt to determine the clinical characteristic and risk factors of POP after hip fracture surgery in a well-defined hip fracture cohort.

METHODS

Datasets from a prospective hip fracture cohort study with a 2-year follow-up period, from 2000 to 2011, were reanalyzed for characteristics of POP. Multivariate Cox proportional regression was used to evaluate the association between the incidence of POP and all-cause mortality. Multivariate logistic regression was used to screen for potential risk factors of POP by analyzing demographic factors, comorbidities, major clinical interventions, and hematological parameters.

RESULTS

In 1429 patients who underwent hip surgery, the incidence of POP was 4.9 % (n = 70). All-cause mortality of patients with POP was significantly higher than that of patients without POP at 30 days (hazard ratio (HR) 3.05, 95 % confidence intervals (CI) 1.88-4.94), 1 year (HR 1.87, 95 % CI 1.41-2.48), and 2 years (HR 1.57, 95 % CI 1.23-1.99) postoperatively. Multivariate logistic regression showed that intrinsic factors (advanced age, anemia, diabetes, prior stroke, number of comorbidities, ASA score ≥III, and some laboratory biomarkers) as well as major clinical interventions were all significant risk factors for POP.

CONCLUSION

Intrinsic factors and major clinical interventions were all important risk factors of POP in patients after hip fracture surgery. Targeted preventive measures to mitigate the above risk factors may help in reducing the incidence of POP.

Optimizing perioperative care for patients with hip fracture

Hip fracture is one of the most common orthopedic conditions associated with significant morbidity and mortality. Patients with hip fracture are usually older, with significant comorbidities. Delayed surgical treatment beyond 48 hours after admission is associated with significantly higher mortality. Hereby clinicians are presented with the challenge to optimize the complex hip fracture within a short time period. This article reviews the evidence regarding preoperative, intraoperative, and postoperative considerations, and provides insights into the best strategies with which to optimize the patient's condition and improve perioperative outcomes.

Special anesthetic consideration for the patient with a fragility fracture

In this article, an overview is presented of perioperative management of the patient with a fragility fracture, including preoperative risk stratification and optimization, anesthesia risks, anesthesia options, and postoperative pain management. Issues of preoperative evaluation that are of concern for the anesthesiologist because of their direct effect on intraoperative care are discussed. A team interdisciplinary approach and good communication between specialties involved in care of elderly surgical patients is important for optimal patient outcomes and to avoid perioperative complications. Cooperation between anesthesiology and medicine is indispensable in reaching a reasonable consensus regarding preoperative evaluation and should occur on a case-by-case basis.

Treatment of protrusio fractures of the acetabulum in patients 70 years and older

OBJECTIVE

To present clinical, radiographic, and functional outcomes in patients 70 years and older with a protrusio-type acetabulum fracture.

DESIGN

Retrospective case series.

SETTING

Two level 1 trauma centers.

PATIENTS

Between November 2000 and December 2009, 39 consecutive patients older than 70 years with protrusio acetabulum fractures were enrolled.

INTERVENTION

Open reduction internal fixation using a combination of pelvic brim and infrapectineal plates.

MAIN OUTCOME MEASUREMENTS

Clinical, radiographic, and functional outcomes as assessed with the modified Merle d'Aubigné score.

RESULTS

Twelve patients were lost to follow-up (<12 months), and one patient was excluded from analysis because he was treated with a percutaneous technique. The remaining 26 (67%) had a mean follow-up of 34 months (12-127 months). At the final follow-up, radiographic grades were excellent in 15, good in 3, poor in 3, and 5 patients had a total hip arthroplasty (19%) at an average of 18 months after the index procedure .The average modified Merle d'Aubigné score was 16 (9-18); categorized as excellent in 10, very good in 4, good in 7, fair in 2, and poor in 3.

CONCLUSION

In the senior patient with a protrusio acetabulum fracture, a treatment strategy that optimizes preoperative conditions, minimizes operative time and blood loss, achieves a stable concentric hip joint, and encourages immediate postoperative ambulation can result in reasonable clinical, radiographic, and functional outcomes with acceptable morbidity. This appears to remain true even in the face of a less than anatomic reduction.

Medical management in the acute hip fracture patient: a comprehensive review for the internist

Each year, more than 250,000 Americans will suffer a broken hip from a fall from no more than standing height. The National Osteoporosis Foundation estimates that more than 500,000 acute hip fractures will occur annually by the year 2040. The costs associated with this healthcare phenomenon are staggering and will continue to increase with an aging population.Hospitalists routinely comanage orthopedic patients as either consultants or as primary physicians in the hospital setting. A unique set of problems exists in this population. Among them are perioperative cardiac risk, perioperative anemia from acute blood loss, venous thromboembolism prophylaxis, and problems with the timing of surgery. It is imperative that hospitalists understand the orthopedic surgeon's point of view in managing these particular problems and become familiar with the evidence supporting or refuting treatment modalities related to these subject areas. In addition, an understanding of the anatomy and surgical options and complications related to each type of fracture allows the hospitalist to become familiar with postoperative rehabilitation needs. It cannot be overstated that addressing hip fracture prevention must be a part of every patient's perioperative care because the incidence of a repeat fracture is significant. Morbidity related to the fracture and comorbidities also need close examination.This article aims to provide a solid understanding of the issues associated with the acute hip fracture population to enhance practice and allow for the best outcome for patients.
