Clinical Practice Guidelines Decrease Unnecessary Echocardiograms Before Hip Fracture Surgery

Preoperative Consultations and Their Effect on Surgical Delays and Mortality in Hip Fracture Surgery

OBJECTIVE

The impact of preoperative consultations on mortality and morbidity rates, and their association with delays and hospital stays for surgery, remains a topic of discussion. This study aims to elucidate the necessity of consultations for those undergoing femoral neck fracture surgery, examining their influence on delays, hospital durations, and their correlation with mortality rates.

METHODS

The study examined data from 320 emergency department patients with femoral neck fractures undergoing hip arthroplasty surgery at our hospital between 2011 and 2021, using digital medical records. Patients were consulted in relevant departments for risk optimization. They were categorized into two groups based on the time of surgery: Group 1 (operated within 48 h) and Group 2 (delayed surgery). The analysis included days from admission to surgery, total hospital stay, and time from surgery to discharge. Mortality rates, with a minimum 2-year follow-up, were assessed using digital records, patient contact, or a death notification system. Statistical analyses involved Mann-Whitney U, Kruskal-Wallis, post hoc analysis, Pearson's chi-squared, and Fisher-Freeman-Halton tests (α = 0.05). SPSS v25.0 software was used.

RESULTS

Patients with consultation requests experience significantly delayed surgery compared to those without (p < 0.001). Statistically significant differences were observed between consulted and nonconsulted groups in time until surgery (p < 0.001), time from surgery to discharge (p < 0.001), and overall length of hospital stay (p < 0.001). However, there is no statistically significant difference in 30-day and 1-year mortality between consulted and nonconsulted patients, both departmentally and overall.

CONCLUSION

This study found that advanced age and high ASA scores were the main factors causing surgical delays in hip fracture patients. While modifiable comorbidities could reduce hospital stays, they did not significantly affect postoperative mortality. Streamlining elective consultations and reducing organizational delays could help prevent delayed surgeries and improve outcomes.

Patient, provider, and system-level factors associated with preoperative cardiac testing: A systematic review

BACKGROUND

Overuse of preoperative cardiac testing contributes to high healthcare costs and delayed surgeries. A large body of research has evaluated factors associated with variation in preoperative cardiac testing. However, patient, provider, and system-level factors associated with variation in testing have not been systematically studied.

OBJECTIVE

To conduct a systematic review to better delineate the patient, provider, and system-level factors associated with variation in preoperative cardiac testing.

METHODS

We included studies of an adult US population evaluating a patient, provider, or system-level factor associated with variation in preoperative cardiac testing for noncardiac surgery since 2012. Our search strategy used terms related to preoperative testing, diagnostic cardiac tests, and care variation with Ovid MEDLINE and Embase from inception through January 2023. We extracted study characteristics and factors associated with variation and qualitatively analyzed them. We assessed risk of bias using the Newcastle-Ottawa Scale and Evidence Project Risk of Bias tool.

RESULTS

Twenty-eight articles met inclusion criteria. Older age and higher comorbidity were strongly associated with higher-intensity testing. The evidence for provider and system-level covariates was weaker. However, there was strong evidence that a focus on primary care and away from preoperative clinic and cardiac consultations was associated with less testing and that interventions to reduce low-value testing can be successful.

CONCLUSIONS

There is significant interprovider and interhospital variation in preoperative cardiac testing, the correlates of which are not well-defined. Further work should aim to better understand these factors.

Preoperative echocardiography for patients with hip fractures undergoing surgery in a low-resource setting: Asset or obstacle?

The aim of this study was to determine the rate of preoperative transthoracic echocardiography in hip fracture patients and to evaluate its effects on time to surgery and length of stay. We conducted a retrospective review of all patients with hip fractures treated at a tertiary referral hospital. Data examined included age, sex, comorbidities, time to surgery, length of stay, fracture type and transthoracic echocardiography findings. Forty-eight patients with hip fractures underwent surgery (men 41.7%; mean age 77.2 (49-95)). Nine patients (18.7%) had a preoperative transthoracic echocardiography. Preoperative transthoracic echocardiography was associated with a significantly longer time to surgery an abbreviation for days e.g dys should be added after the values to indicate what time frame is being measured (14.7 versus 6.8, p = 0.0051) and length of stay (23.6 versus 10.4, p = 0.0002). This study demonstrates a high rate of preoperative transthoracic echocardiography in hip fracture patients. The role of transthoracic echocardiography should be reassessed in view of its association with significant surgical delays.

Impact of Preoperative Echocardiograms on In-Hospital Outcomes of Patients Undergoing Surgical Hip Fracture Repair and Their Clinical Appropriateness

OBJECTIVES

Preoperative transthoracic echocardiograms (TTE) before hip fracture repairs are controversial. This study aimed to quantify the frequency of ordering TTE, the appropriateness of testing based on current guidelines, and the impact of TTE on in-hospital morbidity and mortality outcomes.

METHODS

This retrospective chart review of adult patients admitted with hip fracture compared the length of stay (LOS), time to surgery, in-hospital mortality, and postoperative complications between TTE and non-TTE groups. TTE patients were risk stratified using the Revised Cardiac Risk Index (RCRI) to compare TTE indication according to current guidelines.

RESULTS

Of the 490 patients included in this study, 15% received preoperative TTE. The median LOS of the TTE and non-TTE groups was 7.0 and 5.0 d, respectively, whereas the median time to surgery was 34 and 14 h, respectively. The odds of in-hospital mortality remained significantly higher in the TTE group after adjusting for RCRI but not when adjusted for the Charlson Comorbidity Index. Significantly more patients in the TTE groups had postoperative heart failure and up triage in the intensive care unit. Furthermore, 48% of patients with an RCRI score of 0 received preoperative TTE, with cardiac history as the most typical indication. TTE changed perioperative management in 9% of patients.

CONCLUSIONS

Patients subjected to TTE before hip fracture surgery had a longer LOS and time to surgery, with higher mortality and intensive care unit up triage rates. TTE evaluations were typically conducted for inappropriate indications, which rarely made meaningful changes to patient management.

Process mapping of hip fracture orthogeriatric care: Experience from a tertiary hospital in Malaysia

Background: Early surgical repair and mobilization postoperatively is associated with improved outcomes for older people with hip fractures. A process mapping exercise was performed to identify the delivery of this aspect of care in a tertiary center. Methods: Analysis was done on electronic health record data of those ≥65 years who had surgery over a 3-month period. Barriers to surgery within 48 h of admission, and mobilized within the day after surgery were identified. Results: Fourty-two patients had surgery where the majority were female, had an average age of 78 years, frail, and multimorbid. 10/42 (23.8%) and 9/42 (21.4%) patients were operated on and mobilized early. Eighteen (42.9%) patients had pre-operative cardiology assessment and 19 patients (45.2%) had pre-operative echocardiogram. None led to a change in the surgical management plan. Other reasons for the delay to early surgery included the need for further medical optimization, financial constraints, blood transfusion, and being on antiplatelet/anticoagulant. Barriers to early mobilization postoperatively were lack of weekend service, delayed referral to therapists, pain, hypotension, anemia, and delirium. Conclusions: Streamlining referrals, agreed clinical pathways, consolidating multidisciplinary involvement, and continuous audit would address the barriers identified in delivering early surgical repair and mobilization post-operatively.

Early versus delayed surgery for hip fragility fractures in patients treated with direct oral anticoagulants

BACKGROUND

Delaying surgical treatment for hip fragility fractures increases mortality, but early intervention in patients treated with direct oral anticoagulant (DOAC) may increase the risk of perioperative blood loss due to residual drug activity. This study aimed to evaluate the effect of the timing of hip fragility fractures surgeries in patients treated with DOAC.

METHODS

We retrospectively reviewed all records of DOAC-treated patients who underwent surgery for hip fragility fractures between 2011 and 2019. They were divided into three groups according to time to surgery since admission to the emergency room (ER),  ≤ 24, 24-48, and  ≥ 48 h. Blood loss, peri and postoperative complications, readmissions, and short- and long-term mortality were compared between groups.

RESULTS

Of the 171 suitable patients (59 males and 112 females), 32 (18.7%) were in the  ≤ 24 h group, 93 (54.4%) in the 24-48 h group, and 46 (26.9%) in the  ≥ 48 h group. Timing of surgery did not affect blood loss, as indicated by changes in pre- and postoperative hemoglobin levels (p = 0.089) and proportion of perioperatively administered packed cells (p = 0.949). There was a trend towards increased 30-day mortality in the  ≥ 48 h group compared to the 24-48 h and ≤ 24 h groups (13.0, 4.3 and 3.1%, respectively. p = 0.099), and a trend towards increased 90 day mortality (6.5, 3.2, and 0%, respectively. p = 0.298).

CONCLUSIONS

Early surgery did not increase perioperative blood loss. Delayed surgery  ≥ 48 h of patients receiving DOAC who underwent surgery for hip fragility fractures showed a trend towards increased 30 day and 90 day mortality.

Advances in Geriatric Hip Fractures: Pre-Operative Considerations and Tips to Optimize Outcome

Geriatric hip fractures are complicated by increased morbidity and mortality, and their incidence continues to rise around the world. Frequent considerations in treating geriatric hip fractures include optimal time to surgery, need for preoperative cardiac clearance, risks of operating through anticoagulation, utilization of regional anesthesia, and collaborative care between treatment teams. This article aims to summarize these factors as well as to provide some tips and tricks that can be helpful in their surgical management.

Unnecessary Preoperative Cardiology Evaluation and Transthoracic Echocardiogram Delays Time to Surgery for Geriatric Hip Fractures

OBJECTIVE

Delays to surgery for patients with geriatric hip fracture are associated with increased morbidity and mortality. The American Heart Association (AHA) and American College of Cardiology (ACC) Clinical Practice Guidelines (CPG) were created to standardize preoperative cardiology consultation and transthoracic echocardiogram (TTE). This study's purpose is to determine if these practices are over used and delay time to surgery at a safety net hospital.

DESIGN

Retrospective review.

SETTING

Level 1 trauma center and safety net hospital.

PATIENTS

Charts were reviewed for indications of preoperative cardiology consultation or TTE per AHA and ACC CPG in 412 patients admitted with geriatric hip fracture.

INTERVENTION

Criteria meeting the AHA/ACC guidelines for preoperative TTE and cardiac consultations.

MAIN OUTCOME MEASUREMENTS

Time to surgical intervention.

RESULTS

Despite 17.7% of patients meeting criteria, 44.4% of patients received cardiology consultation. Of those patients, 33.8% met criteria for receiving preoperative TTE but 89.4% received one. Time to surgery was greater for patients receiving cardiology consultation (25.42 ± 14.54 hours, P-value <0.001) versus those who did not (19.27 ± 13.76, P-value <0.001) and for those receiving preoperative TTE (26.00 ± 15.33 hours, P-value <0.001) versus those who did not (18.94 ± 12.92, P-value <0.001).

CONCLUSIONS

Cardiology consultation and TTE are frequently used against AHA/ACC CPG. These measures are expensive and delay surgery, which can increase morbidity and mortality. These findings persisted despite limited resources available in a safety net hospital. Hospitals should improve adherence to CPG, or modify protocols.

Clinical Practice Guidelines on Ordering Echocardiography Before Hip Fracture Repair Perform Differently from One Another

BACKGROUND

Osteoporotic hip fractures typically occur in frail elderly patients with multiple comorbidities, and repair of the fracture within 48 h is recommended. Pre-operative evaluation sometimes involves transthoracic echocardiography (TTE) to screen for heart disease that would alter peri-operative management, yet TTE can delay surgery and is resource intensive. Evidence suggests that the use of clinical practice guidelines (CPGs) can improve care. It is unclear which guidelines are most useful in hip fracture patients.

QUESTIONS/PURPOSES

We sought to evaluate the performance of the five commonly used CPGs in determining which patients with acute fragility hip fracture require TTE and to identify common features among high-performing CPGs that could be incorporated into care pathways.

PATIENTS AND METHODS

We performed a retrospective study of medical records taken from an institutional database of osteoporotic hip fracture patients to identify those who underwent pre-operative TTE. History and physical examination findings were recorded; listed indications for TTE were compared against those given in five commonly used CPGs: those from the American College of Cardiology/American Heart Association (ACC/AHA), the British Society of Echocardiography (BSE), the European Society of Cardiology and the European Society of Anaesthesiology(ESC/ESA), the Association of Anaesthetists of Great Britain and Ireland (AAGBI), and the Scottish Intercollegiate Guidelines Network (SIGN). We then calculated the performance (sensitivity and specificity) of the CPGs in identifying patients with TTE results that had the potential to change peri-operative management.

RESULTS

We identified 100 patients who underwent pre-operative TTE. Among those, the patients met criteria for TTE 32 to 66% of the time, depending on the CPG used. In 14% of those receiving TTE, the test revealed new information with the potential to change management. The sensitivity of the CPGs ranged from 71% (ESC/ESA and AAGBI) to 100% (ACC/AHA and SIGN). The CPGs' specificity ranged from 37% (BSE) to 74% (ESC/ESA). The more sensitive guidelines focused on a change in clinical status in patients with known disease or clinical concern regarding new-onset disease.

CONCLUSIONS

In patients requiring fixation of osteoporotic hip fractures, TTE can be useful for identifying pathologies that could directly change peri-operative management. Our data suggest that established CPGs can be safely used to identify which patients should undergo pre-operative TTE with low risk of missed pathology.

Preoperative Noninvasive Cardiac Testing in Older Adults with Hip Fracture: A Multi-Site Study

BACKGROUND/OBJECTIVES

For older adults with acute hip fracture, use of preoperative noninvasive cardiac testing may lead to delays in surgery, thereby contributing to worse outcomes. Our study objective was to evaluate the preoperative use of pharmacologic stress testing and transthoracic echocardiogram (TTE) in older adults hospitalized with hip fracture.

DESIGN

Retrospective chart review.

SETTING

Seven hospitals (three tertiary, four community) within a large health system.

PARTICIPANTS

Patients, aged 65 years and older, hospitalized with hip fracture (n = 1,079; mean age = 84.2 years; 75% female; 82% white; 36% married).

MEASUREMENTS

Data were extracted from electronic medical records. The study evaluated associations between patient factors as well as clinical outcomes (time to surgery [TTS], length of stay [LOS], and in-hospital mortality) and the use of preoperative noninvasive cardiac testing (pharmacologic stress tests or TTE). Descriptive statistics were calculated. Cox regression was performed for both TTS and LOS (evaluated as time-dependent variable); logistic regression was used for in-hospital mortality.

RESULTS

Although 34.3% (n = 370) had a preoperative TTE, .7% (n = 8) underwent a nuclear stress test and none had a dobutamine stress echocardiogram. Median TTS was 1.1 days (IQR [interquartile range] = .8-1.8 days), median LOS was 5.3 days (IQR = 4.2-7.2 days), and in-hospital mortality was 3% (n = 32). Patients admitted to the medical service had 3.5 times greater odds of undergoing a TTE compared with those on the orthopedic service (P < .001). Community hospitals had almost three times greater odds of preoperative TTE than tertiary centers (P < .001). In multivariable analysis, preoperative TTE was significantly associated with increased TTS (P < .001). No difference in mortality was found between patients with and without a preoperative TTE.

CONCLUSION

This study highlights the high rate of TTE in preoperative assessment of older adults with acute hip fracture. Given the association between TTE and longer TTS, further studies must clarify the role of preoperative TTE in this population. J Am Geriatr Soc 68:1690-1697, 2020.

Hospital-based Hip fracture programs: Clinical need and effectiveness

Hospital-based hip fracture programs are essential for effective, efficient care of elderly patients who have sustained hip fractures. Many of the gains in outcomes and patient survival are a result of such integrated care models. We review the rationale, elements, and benefits of such programs across the spectrum of inpatient centers, including low-volume and high-volume community hospitals and trauma centers.

Hip fracture clearance: How much optimisation is necessary?

Patients with hip fractures are typically elderly individuals with several co-morbidities. Upon admission to the hospital, they often present with acute pain, electrolyte disturbances, anaemia, coagulopathy, and delirium. Long waiting times for surgery are associated with increased morbidity and mortality. The balance between the number of clinical tests and optimisation, which may (i.e., fewer complications and better survival) or may not (i.e., more complications and increased mortality due to unnecessary surgical delay) benefit the patient, has been a preoperative challenge. This summary will review existing clinical guidelines and relevant selected studies to evaluate the extent of preoperative optimisation needed prior to hip fracture surgery.

Evaluation of the Clarity and Completeness of Reporting in Orthopedic Clinical Practice Guidelines

Background

Clinical practice guidelines (CPGs) can positively affect the quality of patient care offered by physicians because they decrease variability in clinical practice and may help reduce unnecessary testing, promoting a more responsible use of resources. Building on existing framework for reporting guideline development, including the work of the Enhancing the Quality and Transparency of Health Research Network, the Reporting Items for Practice Guidelines in Healthcare (RIGHT) Working Group created a 2016 checklist of 35 items considered essential for high-quality reporting of CPGs.

Objectives

To evaluate how many previously published CPGs in orthopedic surgery met the RIGHT criteria and assess how improvements can be made in future orthopedic CPGs based on any found deficiencies.

Methods

All 18 CPGs published before January 1, 2018, by the American Academy of Orthopedic Surgeons (AAOS) are publicly available on orthoguidelines.org. Two authors downloaded each file and both of those authors independently scored each CPG using piloted abstraction RIGHT checklist forms.

Results

Of the 35 RIGHT criteria outlined in 22 checklist items, 23 (65.7%) were met across all AAOS guidelines, 6 (17.1%) were not met by any of the AAOS guidelines, and 6 (17.2%) were met by some of the AAOS guidelines.

Conclusion

Overall, the AAOS guidelines addressed many important recommendations within the RIGHT checklist. Assessing adherence to the RIGHT checklist can help ensure that future guidelines are more effectively communicated, hopefully assisting end users in efficient implementation and increasing the level of evidence-based patient care.

Cardiac overscreening hip fracture patients

BACKGROUND

The aim of this study was to prospectively investigate the adherence to the American College of Cardiology (ACC) and the American Heart Association guidelines for perioperative assessment of patients with hip fracture in daily clinical practice and how this might affect outcome.

METHODS

This prospective cohort study from Maastricht University Medical Centre included 166 hip fracture patients within a 3-year inclusion period. The preoperative cardiac screening and adherence to the ACC/AHA guideline were analyzed. Cardiac risk was classified as low, intermediate and high risk. Secondary outcome measurements were delay to surgery, perioperative complications and in-hospital, 30-day, 1-year and 2-year mortality.

RESULTS

According to the ACC/AHA guideline, 87% of patients received correct preoperative cardiac screening. The most important reason for incorrect preoperative cardiac screening was overscreening (> 90%). Multivariate analysis showed that a cardiac consultation (p = 0.003) and overscreening (p = 0.02) as significant predictors for increased delay to surgery, while age, sex, previous cardiac history and preoperative mobility were not. High risk patients had in comparison with low risk patients a significantly higher relative risk ratio for in-hospital mortality (RR 6, 95% CI 2-17). Multivariate analysis showed that a previous cardiac history and increased delay to surgery were predictors for early mortality. High age and previous cardiac history were risk factors for late mortality.

CONCLUSION

Preoperative cardiac screening for hip fracture patients in adherence to the ACC/AHA guideline is associated with a diminished use of preoperative resources. Overscreening leads to greater delay to surgery, which poses a risk for perioperative complications and early mortality.

Clinical predictors of postoperative delirium, functional status, and mortality in geriatric patients undergoing non-elective surgery for hip fracture

STUDY OBJECTIVE

To identify modifiable preoperative factors that might influence the morbidity and mortality associated with non-elective, inpatient hip fracture surgeries in the geriatric surgical population.

DESIGN

Retrospective database analysis from the American College of Surgeons National Surgical Quality Improvement Program Geriatric Surgery Pilot Project.

SETTING

Inpatient, perioperative.

PATIENTS

Geriatric patients undergoing surgery.

INTERVENTIONS

Non-elective hip repair surgery.

MEASUREMENTS

Preoperative demographic, medical, surgical, and anesthetic variables; post-operative rates of delirium, decline in functional status, and 30-day mortality.

MAIN RESULTS

The 1261 patients in this study were predominantly female (74%), white (89%), and non-Hispanic (92%). Ages were distributed across groups from 65 to over 90 years. Most patients were categorized as American Society of Anesthesiologists Physical Status class 3 (64%). General anesthesia (57%) was the most common anesthetic, followed by spinal (38%). Preoperative functional status was recorded in 79% as independent in activities of daily living (ADLs). About one third of patients had baseline dementia. Post-operatively, 42% experienced delirium, and most patients required partial or total assistance with ADLs (72% and 12%, respectively). Reoperation was required in 2.8% of cases. Mortality at 30 days was 5.0%. In the multivariable analysis, risk factors associated with post-operative delirium included dementia and lack of competency to sign consent. In the analysis for postoperative decline in functional status, the major risk factor was a history of falls, while emergently performed surgery was protective. The analysis for mortality at thirty days was under-powered.

CONCLUSIONS

Hip fractures remain a major source of morbidity in geriatric patients. Baseline dementia and inability to sign surgical consent are significant risk factors for adverse outcomes after hip fractures and should be considered in the informed consent process. Data from this study and currently ongoing randomized trials will help guide reductions in morbidity and mortality in this population.

Reducing the Cost of Medicaid: A Multistate Simulation

According to some estimates, the United States wastes as much as 30% of health care dollars. Some of that waste can be mitigated by reducing certain costs associated with Medicaid. We chose 5 areas of savings applicable to Medicaid: (1) modification of physician payment models to reduce unnecessary care, (2) development of a medication adherence program for patients dually eligible for Medicaid and Medicare support ("dual eligibles"), (3) improvement in unnecessary admissions and readmissions for dual eligibles, (4) reduction in emergency department visits among children in Medicaid and dual-eligible beneficiaries, and (5) improvement in adoption of end-of-life advance directives. We chose the states from both ends of the spending spectrum: the 5 with the lowest annual Medicaid expenditures: Wyoming, South Dakota, Montana, Vermont, and Alaska, and those with the highest: California, New York, Texas, Pennsylvania, and Florida. This spectrum demonstrates the range of potential cost-saving measures, from US $23.6 million in Wyoming to US $3.4 billion in California. We conclude that there are a number of ways to reduce Medicaid spending and improve quality. To the extent that states have already adopted programs addressing the same problems, our approach may be supplementary but the total savings may be achieved with a combination of current initiative and those described here. As Medicaid creates savings, physician payment could be increased to attract more physicians into caring for Medicaid patients.

Retrospective Analysis of Geriatric Patients Undergoing Hip Fracture Surgery: Delaying Surgery Is Associated With Increased Morbidity, Mortality, and Length of Stay

Introduction:

Hip fractures are common in elderly patients. However, this population frequently presents with significant medical comorbidities requiring extensive medical optimization.

Methods:

This study sought to elucidate optimal time to surgery and evaluate its effect on postoperative morbidity, mortality, and length of stay (LOS). We performed a retrospective analysis of data collected from 2008 to 2010 on 841 patients who underwent hip fracture surgery. Patients were classified based on time to surgery and were also classified and analyzed according to the American Society of Anesthesiologists (ASA) physical classification system.

Results:

Patients with a delay of greater than 48 hours had a significant increase in overall LOS, postoperative days, and overall postoperative complications. Patients classified as ASA 4 had an odds ratio for postoperative morbidity of 3.32 compared to the ASA 1 and 2 group (P = .0002) and 2.26 compared to the ASA 3 group (P = .0005). Delaying surgery >48 hours was also associated with increased in-hospital mortality compared to 24 to 48 hours (P = .0197). Increasing ASA classification was also associated with significantly increased mortality. Patients classified as ASA 4 had 5.52 times the odds of ASA 1 and 2 (P = .0281) of in-hospital mortality. Those classified ASA 4 had 2.97 times the odds of ASA 3 (P = .0198) of an in-house mortality. Anesthetic technique (spinal vs general) and age were not confounding variables with respect to mortality or morbidity.

Discussion:

Surgical timing and ASA classification were evaluated with regard to LOS, number postoperative days, morbidity, and mortality.

Conclusions:

Delaying surgery >48 hours, especially in those with increased ASA classification, is associated with an increase in overall LOS, postoperative days, morbidity, and mortality. However, rushing patients to surgery may not be beneficial and 24 to 48 hours of preoperative optimization may be advantageous.
