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

IntroductionAlthough 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 MethodsIn 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.ResultsIn 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).ConclusionsThese results support current guidelines, which recommend early surgery for elderly hip fractures patients.     

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

Summary

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.

目的: 探讨老年髋部骨折术后健侧骨折的发生率及其相关危险因素为预防再次骨折提供依据。方法: 回顾分析2012年6月至2017年6月接受髋关节置换术或股骨近端髓内钉固定术治疗的65岁以上股骨颈骨折或转子间骨折452例患者的临床资料,男168例,女284例;年龄65~97(75.5±7.5)岁;股骨颈骨折191例,股骨转子间骨折261例;按照术后健侧髋部是否存在骨折,分为骨折组和无骨折组,记录两组患者性别、年龄、体质量指数、骨折类型、初次治疗方式、骨密度、医疗依从性、术后是否短期谵妄、伤前是否并存内科疾病及末次随访髋关节Harris评分。应用单因素Logostic回归分析筛选出术后健侧骨折的危险因素,再将有统计学意义的危险因素纳入多因素Logostic回归分析,筛选出老年髋部骨折术后健侧骨折的独立危险因素。结果: 452例患者中42例发生健侧髋部骨折,发生率为9.3%,两次骨折发生相隔时间平均(2.9±2.1)年。单因素Logistic回归分析结果示年龄、骨密度、医疗依从性、术后短期谵妄、伤前合并内科疾病及末次随访髋关节Harris评分差异均有统计学意义(P<0.05)。多因素Logistic分析显示年龄(OR=4.227)、骨密度(OR=4.313)、合并内科疾病(OR=5.616),以及末次随访髋关节Harris评分分级低(OR=3.891),是老年髋部骨折术后健侧骨折的独立危险因素(P<0.05)。结论: 年龄、骨密度、合并内科疾病以及末次随访髋关节Harris评分分级低是老年髋部骨折术后健侧骨折的主要危险因素,术后3年内要加强内科疾病的治疗,抗骨质疏松,改善髋关节功能,以预防健侧髋部骨折的发生。     

The influence of anesthetic techniques on postoperative cognitive function in elderly patients undergoing hip fracture surgery: General vs spinal anesthesia

BackgroundHip fracture is common and morbid in elderly patients. Postoperative cognitive dysfunction (POCD) is also very common in these subjects undergoing surgery with an incidence which exceeds 40% in some reports. To date, the evidence is ambiguous as to whether anesthetic technique may affect the patients’ outcome as far as postoperative cognitive function is concerned.ObjectiveThe aim of this study was to compare the effect of general and subarachnoid (spinal) anesthesia on the development of POCD up to 30 days after surgery in elderly patients undergoing hip fracture surgery.Methods Subjects over 65 years with hip fracture undergoing surgery were recruited for this study. They were enrolled and randomized to receive either general anesthesia (GA group) or subarachnoid (spinal) anesthesia (S group). Cognitive function was assessed using a battery of neuropsychological tests undertaken preoperatively and at 30 days postoperatively. The incidence of delirium was examined during the same period and their functional status, in terms of activities of daily living was also recorded.ResultsA total of seventy patients, 33 men and 37 females, mean age of 76 years were analyzed. Thirty-three patients received general anesthesia (GA group) and 37 subarachnoid (spinal) anesthesia (S group). The two groups of patients were similar with respect to baseline characteristics, comorbidities and perioperative data. The results of neuropsychological testing showed that there were no significant differences between the groups in eight out of ten neurocognitive tests at baseline and 30 days after surgery. There was a statistically significant decline of the Instrumental Activities of Daily Living Scale score in S group compared with group GA on the 30th postoperative day (p = 0.043). A significant decline was also present in Color-Word Task test in S group compared with group GA at baseline (p = 0.014) and 30 days postoperatively (p = 0.003). Postoperative delirium was present in four patients (12%) for the GA group, and in 10 patients (27%) for the group receiving subarachnoid anesthesia.ConclusionWe concluded that the choice of anesthesia modality does not appear to influence the emergence of postoperative cognitive dysfunction in elderly patients undergoing hip fracture surgery.     

Pre-Emptive Antifibrinolysis: Its Role and Efficacy in Hip Fracture Patients Undergoing Total Hip Arthroplasty

BackgroundWe aimed to determine the efficacy of pre-emptive antifibrinolysis with tranexamic acid (TXA) in decreasing hidden blood loss (HBL) in the elderly hip fracture patients.MethodsNinety-six elderly hip fracture patients receiving hip arthroplasty were randomized to receive 100 mL of normal saline (group A) or 1.5 g of TXA (group B) intravenously q12 hours from postadmission day 1 (PAD1) to the day before surgery. Both groups were treated with 1.5 g of TXA q12 hours from postoperative day 1 (POD1) to POD3. HBL was calculated by formulas and recorded as the primary outcome.ResultsIn overall analyses, no difference was found in HBL, while the decline of hemoglobin (ΔHb), allogeneic blood transfusion (ABT) rate, fibrinogen degradation product (FDP—on PAD2, PAD3, POD1, and POD2), and d-dimer (D-D—on PAD2, PAD3, and POD1) were lower in group B. In subgroup analyses for patients receiving intervention within 72 hours of injury, group B had lower postoperative HBL, ΔHb, ABT rate, FDP, and D-D levels (on PAD2, PAD3, POD1, and POD2). For patients receiving intervention over 72 hours after injury, no difference was detected in perioperative HBL, ΔHb, and ABT rate between the 2 groups. The FDP and D-D levels were lower in group B on PAD2 and PAD3. No difference was found in coagulation parameters, wound complications, venous thromboembolism rate, and 90-day mortality in all analyses.ConclusionEarly administration (within 72 hours of injury) of multidose of TXA is effective in reducing perioperative HBL in elderly hip fracture patients. Delayed use (over 72 hours after injury) of TXA was not beneficial.     

Postoperative pneumonia after bariatric surgery during the COVID-19 pandemic: a National Surgical Quality Improvement Program study

BackgroundDuring the COVID-19 pandemic, surgical centers had to weigh the benefits and risks of conducting bariatric surgery. Obesity increases the risk of developing severe COVID-19 infections, and therefore, bariatric surgery is beneficial. In contrast, surgical patients who test positive for COVID-19 have higher mortality rates.ObjectiveThis study investigates the national prevalence of postoperative pneumonia during the COVID-19 pandemic in the bariatric surgery population.SettingThe American College of Surgeons National Surgical Quality Improvement Project (ACS-NSQIP) database.MethodsThis is a cross-sectional study using the ACS-NSQIP database. The population of concern included patients who underwent sleeve gastrectomy and Roux-en-Y gastric bypass procedures. Information was extracted on rate of postoperative pneumonia and other 30-day complications between 2018 and 2020.ResultsAll baseline characteristics were similar among patients who underwent bariatric surgery between 2018 and 2020. However, there was a 156% increase in postoperative pneumonia in 2020 compared with the previous year. Furthermore, despite the similar postoperative complication rates across the years, there was a statistically significant increase in all-cause mortality in 2020. The multivariate analysis showed that having surgery in 2020 was a statistically significant risk factor for pneumonia development postoperatively.ConclusionsThis study showed a statistically significant increase in the prevalence of postoperative pneumonia during the COVID-19 pandemic among bariatric surgery patients. Surgical centers must continuously evaluate the risks associated with healthcare-associated exposure to COVID-19 and weigh the benefits of bariatric surgery.     

Is preoperative balloon aortic valvuloplasty of interest for severe aortic stenosis in hip fracture surgery?

PurposeIn elderly patients, the discovery and management of a severe aortic stenosis (AS) prior to emergency non-cardiac surgery is a frequent and controversial issue. The objective of this study was to evaluate preoperative balloon aortic valvuloplasty (BAV) for severe AS in hip fracture surgery.MethodsWe conducted an observational, monocentric, retrospective study from 2011 to 2018. Survival (30-day, 90-day and 180-day mortality) and the occurrence of perioperative complications were analyzed and compared between control (i.e. no BAV prior to surgery) and preoperative BAV groups in patients with hip fracture surgery and a formal transthoracic echocardiographic diagnosis of severe AS (aortic valve area < 1 cm²). Patients' allocation to the intervention and control groups was after a discussion between cardiologist, anesthesiologist and the surgeon.ResultsAmong the 8506 patients who underwent hip fracture surgery, 29 patients in the control group and 30 patients in the BAV group were finally included. Kaplan-Meier survival analysis demonstrated a significant decrease in mortality in the BAV group (p=0.014) despite an increase in median time to operation of about 48 hours (p<0.0001). Multivariate analysis (stepwise logistic regression) showed that postoperative delirium (OR [95%CI]: 17.5 [1.8-168]; p=0.013) and postoperative acute congestive heart failure (OR [95%CI]: 59.4 [5.0-711.1]; p=0.0013) were predictive factors of 30-day mortality with an area under ROC curve of 0.90 (95%CI: 0.80-0.97; p<0.0001).Conclusionspreoperative BAV for severe AS could reduce the mortality of hip fracture patients despite an increase in time to operation. This improved survival could be linked to the decrease in cardiologic and neurologic adverse events. A larger prospective randomized study is necessary before generalizing our results.     

Quality of life after hip fracture in the elderly: A systematic literature review

BackgroundWith an increasing ageing population, hip fractures have become a major public health issue in the elderly. It is important to examine the health status (HS) and health-related quality of life (HRQOL) of the elderly faced with the epidemic of hip fractures.ObjectiveTo provide an overview of reported HS and HRQOL in elderly patients with a hip fracture.DesignA systematic literature search was performed in Embase, Medline, Web of Science, Scopus, CINAHL, Cochrane, PsycINFO, Pubmed, and Google Scholar in July 2014. Studies which reported the HS or HRQOL based on standardised questionnaires in patients older than 65 years with a hip fracture were considered eligible for inclusion.ResultsAfter inspecting the 2725 potentially eligible studies, 49 fulfilled the inclusion criteria. All included studies were randomised controlled trials or prospective cohort studies. The methodological quality of the studies was moderate. Patients’ functioning on the physical, social, and emotional domains were affected after a hip fracture. The HS and HRQOL of the majority of patients recovered in the first 6 months after fracture. However, their HS did not return to prefracture level. Mental state, prefracture functioning on physical and psychosocial domains, comorbidity, female gender, nutritional status, postoperative pain, length of hospital stay, and complications were factors associated with HS or HRQOL. Treatment with total hip arthroplasty or hemi-arthroplasty provided better HS than treatment with internal fixation with displaced femoral neck fractures. Supportive psychotherapy in “low-functioning” patients, (home) rehabilitation programmes and nutritional supplementation appeared to have beneficial effects on HS.ConclusionsOptimizing nutrition intake, (home) rehabilitation programmes, and the possibility for psychological counselling in patients with difficulties in the psychosocial dimensions would be recommended after hip fracture surgery. Besides HS questionnaires like EQ-5D and SF-36, adequate measurements like the WHOQOL-Bref or ICECAP-O are warranted in future studies regarding hip fracture surgery and postoperative treatment options.     

Nonagenarian hip fractures: Morbidity and mortality at a single institution

ObjectivesThe incidence of hip fractures continues to rise dramatically, but few studies have examined these injuries in the population of individuals over 90 years of age, which is one of the fastest growing populations. We present the largest such study specifically examining hip fractures in the super-elderly.MethodsA review of 216 hip fracture patients over 90 years of age were examined for immediate postoperative complications and in-house, 30-day, and 1-year mortality.ResultsOverall 1-year mortality was 38.1%. Statistically-significant risk factors for 1-year mortality included oncologic fracture, dementia, and CHF. Fracture classification and hospital length of stay were associated with perioperative complications including anemia and pneumonia.ConclusionThe nonagenarian hip fracture is associated with a higher 1-year mortality than prior reported rates of mortality for elderly hip fractures. Factors previously reported to influence the risk of 1-year mortality in hip fractures are not observed in the super-elderly.     

Effect of surgical delay on 30-day mortality in patients receiving direct oral anticoagulants and admitted for hip fracture

BackgroundEarly hip fracture surgery is recommended to decrease mortality, however the impact of a delay in surgery due to previous treatment with direct oral anticoagulants (DOA) is unknown. Our objective was to determine if early surgery, defined as surgery within 48 h of hospital admission is associated with decreased postoperative mortality. We tested the hypothesis that early surgery was beneficial with regard for mortality in patients treated with direct oral anticoagulants.MethodsRetrospective cohort study in a French University Hospital including patient admitted for Hip fracture. The main exposure was wait time for surgery defined as the total time, in hours, between hospital admission and surgery. The main outcome was mortality within 30 days after hip fracture surgery.ResultsIn 3429 patients, the overall 30-day mortality was 4.1% (95% CI 3.5%; 4.9%). In DOA + patients, the 30-day mortality rates in the early and delayed surgery groups were 1.2% and 5.9%, respectively, with estimated risk difference of -4.4 (with a 2% probability of this difference is > 0). In the DOA + group, early surgery tended to be associated with a higher percentage receiving red-blood cells (64.6% vs 54.8%, respectively, estimated risk difference of 9.9% with a 93% probability of this difference is > 0) and lower risk of pneumonia (1.2% vs 8.2%, respectively; estimated difference of -6.7% with 0.3% probability of superiority).ConclusionEarly hip fracture surgery was associated with improved survival in patients previously treated with DOAs.     

Early postoperative hypoalbuminemia is a risk factor for postoperative acute kidney injury following hip fracture surgery

IntroductionAcute kidney injury (AKI) is a common and serious complication after hip fracture surgery in older adults. Hypoalbuminemia is a known independent risk factor for AKI. However, few studies have investigated the relationship between early postoperative hypoalbuminemia and AKI after hip fracture surgery. Therefore, we sought to determine the incidence of and risk factors for AKI and the effects of early postoperative hypoalbuminemia on AKI incidence after surgery for hip fractures, especially intertrochanteric fractures of the proximal femur.Patients and methodsIn this retrospective cohort study from a single center, we reviewed the medical records of 481 consecutive patients (>60 years) who underwent surgery for intertrochanteric fracture of the proximal femur. Multiple logistic regression was performed to identify independent risk factors for AKI. After determining the cut-off value of the minimal level of postoperative serum albumin during the first two postoperative days, we divided the patients into two groups: group 1 included 251 patients whose minimal early postoperative serum albumin level was <2.9 g/dL during the first two postoperative days; and group 2 included 230 patients whose minimal early postoperative serum albumin level was ≥2.9 g/dL. The incidence of AKI was analyzed using inverse probability of treatment weighting (IPTW), propensity score matching (PSM), and propensity score matching weighting (PSMW) analyses.ResultsThe incidence of AKI, defined based on the Kidney Disease Improving Global Outcomes criteria, was 11.8% (n = 57). Chronic kidney disease and the minimal early postoperative serum albumin level <2.9 g/dL at any point during the first two postoperative days were independent risk factors for AKI. The IPTW, PSM, and PSMW analyses comparing the incidence of AKI between the two groups revealed that the minimal early postoperative serum albumin level <2.9 g/dL was significantly associated with AKI development (P < 0.001, P = 0.025, and P = 0.011, respectively).ConclusionThe incidence of postoperative AKI was 11.8%. Our findings demonstrate that early postoperative hypoalbuminemia is an independent risk factor for AKI in patients undergoing surgery for intertrochanteric fracture of the proximal femur.     

An analysis of cost and complications for patients sustaining a second,contralateral hip fracture within 1 year

IntroductionHip fractures are an increasingly common occurrence among the aging population. With increased life expectancy and advancements in medicine, patients sustaining a hip fracture are at an increasing risk of sustaining a contralateral hip fracture. Efforts are being made to better understand the environment of these hip fractures so that secondary prevention clinics and guidelines can be made to help prevent recurrent osteoporotic hip fractures. The estimated incidence of a contralateral hip fracture varies from 2 to 10% and is reportedly associated with a higher incidence of complications. Previous studies evaluating contralateral hip fractures compared a single cohort of patients sustaining a second hip fracture with patients who sustained only one hip fracture. We aimed to investigate the overall complications and associated costs as it relates to a patients first hip fracture and contrast this to the same patient's contralateral, second hip fractures.MethodsWe performed a retrospective review of all patients in our health systems electronic database who were found to have surgically treated hip fractures between January 2004 and July 2019. Patients with surgically treated hip fractures (CPT Codes: 27235, 27236, 27245, 27244), who sustained a second contralateral hip fracture were included. Medical complications within 30 days of either procedure (such as pneumonia, UTI, altered mental status and others), length of stay, orthopedic complications (such as wound complications, infection, hardware failure, nonunion), type of implants, costs, comorbidities, and ASA Class as well as Mortality were reviewed.ResultsA total of 4,870 hip fractures were identified during the study period where 137 (2.8%) patients sustained a second hip fracture, and 47 (0.9%) of which were sustained within the first year after their index hip fracture. There was no statistical difference in length of stay (p = 0.68), medical (p>0.99) or orthopedic complications (p>0.99) between patients first and second hip fractures. There was an increased incidence of cognitive impairment with the second hip fracture (P = 0.0002). For patients that underwent operative treatment of a second hip fracture, the total cost of care was higher for the second surgery (mean difference 757. 38 USD) however the difference wasn't statistically significant (p = 0.31). The overall 1-year mortality rate was 14.9 percent.ConclusionsOur study demonstrates there is no statistical difference between the first and second surgery regarding length of stay, medical or orthopedic complications and cost.

Incidence,mortality, and complications of acute myocardial infarction with and without percutaneous coronary intervention in hip fracture patients

IntroductionAcute myocardial infarction (AMI) is a common cause of death following hip fracture surgery. This study aimed to determine the incidence and timing of perioperative AMI treated with percutaneous coronary intervention (PCI) in hip fracture patients, and to compare in-hospital mortality and complications between hip fracture patients who did not have an AMI, those who sustained a perioperative AMI and did not undergo PCI, and those who sustained an AMI and underwent PCI.MethodsThe National Inpatient Sample (NIS) was queried from 2010 through the third quarter of 2015 to identify all patients undergoing hip fracture surgery. Patients were stratified into three cohorts: perioperative AMI but no PCI (no PCI cohort), perioperative AMI with PCI (PCI cohort), and no perioperative AMI or PCI (no AMI cohort). Patient demographics, comorbidities, in-hospital mortality, and complications were compared between cohorts. Multivariable logistic regression adjusting for age, sex, procedure, and Elixhauser score was used to assess the relative odds of in-hospital mortality for each cohort.ResultsA total of 1,535,917 hip fracture cases were identified, with 1.9% in the no PCI cohort, 0.01% in the PCI cohort, and 98.0% in the no AMI cohort. In-hospital mortality was lower in the PCI cohort than in the no PCI cohort (8.8% vs. 14%), and was greater for both than in the no AMI cohort (1.6%, p < 0.001 for all). Both the no PCI cohort (OR, 6.1; 95% CI, 5.6–6.6) and PCI cohort (OR, 4.1; 95% CI, 2.8–6.0) had increased adjusted odds of in-hospital mortality compared to the no AMI cohort. The PCI cohort had a higher rate of bleeding complications than both other cohorts, and the no PCI cohort had a higher rate of transfusion than both other cohorts.ConclusionsPerioperative AMI both with and without PCI independently increases the risk of mortality in hip fracture patients, with the highest risk of mortality in those with AMI without PCI. Providers should understand the increased morbidity and mortality associated with AMI in hip fracture patients, as well as the risks and benefits of perioperative PCI, in order to better counsel and manage these patients.Level of EvidenceIII     

Prevalence of preoperative metabolic disturbances in elderly patients with hip fracture and their association with mortality – A retrospective cohort study

Study objectivesTo assess the prevalence of preoperative acidosis and lactatemia in elderly patients having hip fracture surgery and their association with post-operative mortality.DesignRetrospective cohort study.SettingSingle tertiary medical center.PatientsPatients ≥65 years having first traumatic hip fracture surgery between 2018 and 2021.Measurements90-day postoperative mortality.Main resultsIn total, 1267 patients were included in the primary analysis (mean (SD) age 83(8) years; 802 (69%) females; median [Interquartile Range (IQR)] American Society of Anesthesiologists (ASA) physical score 3 [2,3]). Of these, 1227 were available for the multivariable analyses. Median [IQR] time from hospitalization to surgery was 28 [20, 42] hours. All-cause 90-day mortality rate was 9% (N = 114). The incidence of preoperative acidosis (pH < 7.35) and lactatemia (>1.2 mmol/L) was significantly higher among non-survivors. Mortality was highest in patients with both acidosis and lactatemia (19.1% compared to 4.4% among patients with neither). In a multivariable model, pH <7.35 and lactate >1.2 mmol/L remained independent predictors of 90-day mortality, with adjusted odds ratio (aOR) (95%CI) of 1.99 (1.31 to 3.04) and 2.32 (1.44 to 3.74), respectively, p = 0.001 for both. Time from hospitalization to surgery was not associated with mortality after adjustment for metabolic indices, aOR 1.00 (0.99, 1.00).ConclusionsPreoperative acidosis and lactatemia are common among patients ≥65 years having hip fracture surgery and are associated with 90-day all-cause mortality. Time from hospital admission to surgery is not an independent risk factor, once adjusted for metabolic indices. Future studies should evaluate whether the increased risk associated with preoperative metabolic disturbances is modifiable.     

Effects of perioperative oral care on prevention of postoperative pneumonia after lung resection: Multicenter retrospective study with propensity score matching analysis

BackgroundPostoperative pneumonia can be a fatal complication that may occur after lung resection in cancer patients. Some reports have shown that the incidence of postoperative pneumonia is decreased after esophageal surgery by perioperative oral care; however, there exist no data to suggest that a lack of perioperative oral care can be a risk factor for postoperative pneumonia after lung resection. To investigate the association between the preventive effect of oral care and postoperative pneumonia, we conducted a multicenter, retrospective study of lung cancer patients who underwent lung resection.MethodsBetween January 2014 and December 2016, a total of 721 patients underwent lung resections at 1 of the 6 hospitals included in our study. Among 721 patients, 280 (38.8%) received perioperative oral care, and the remaining 441 (61.2%) did not receive any such care. Propensity score matching was performed to minimize selection biases associated with the comparison of retrospective data between the oral care and control groups.ResultsOf the 721 patients, 54 (7.5%) experienced postoperative pneumonia involving 13 of the 280 patients (4.6%) in the oral care group and 41 of the 441 patients (9.3%) in the control group (P = .02). On propensity score analysis, a significant difference was also found between oral care intervention and incidence of postoperative pneumonia (P = .002).ConclusionOur results suggest that perioperative oral care is an effective method to decrease the occurrence of postoperative pneumonia in patients who have undergone lung resection.     

Increased risk of hip fracture mortality associated with intraoperative hypotension in elderly hip fracture patients is related to under resuscitation

BackgroundAs the US and world population ages, hip fractures are increasingly more common. The mortality associated with these fractures remains high both in the immediate postoperative period and at one year. Perioperative resuscitation in this population is of key interest to prevent organ injury and mortality. Our objectives were to evaluate the effect of fluid resuscitation and hemodynamic status in the form of mean arterial pressure (MAP) on inpatient mortality of hip fracture patients.MethodsAn institutional database was queried to compare elderly hip fracture patients that sustained in-hospital mortality to a matched control cohort. Pre-, intra-, and post-operative intravenous fluid (IVF) administration and MAP were extracted from the electronic medical record. Time from hospital presentation to the OR was also recorded.Results1,114 total hip fractures were identified during the two-year study period, 16 of which suffered inpatient mortalities. The mortality cohort was then matched with a control of 394 hip fracture patients for the same period based on age, sex, and Charlson Comorbidity Index (CCI). Conditional logistical regression analysis found odds ratios (OR) indicating that longer time between presentation and surgery (OR per additional hour: 1.05; 95% CI: 1.01–1.08) and lower intraoperative minimum MAP (OR per 5 mmHg decrease: 0.77; 95% CI: 0.61–0.97) were associated with significantly increased odds of mortality. There was also a marginal relationship between greater intraoperative IVF administration and reduced odds of mortality (OR per 500 cc additional fluid: 0.61; 95% CI: 0.37–1.00).ConclusionExtended time from presentation to surgery and intraoperative hypotension were associated with increased likelihood of inpatient mortality in an elderly hip fracture cohort, with a possible additional effect of under-resuscitation. Further investigation into a safe intraoperative minimum MAP should be pursued.Level of evidenceLevel III.     

Perioperative population management for primary hip arthroplasty reduces hospital and postacute care utilization while maintaining or improving care quality

Study objectivePhysician-led multidisciplinary care coordination decreases hospital-associated care needs. We aimed to determine whether such care coordination can show benefits through the posthospital discharge period for elective hip surgery.DesignTime Series of prospectively recorded and historical data.SettingAcademic tertiary care medical center and health system.Patients449 patients undergoing elective primary hip surgery.InterventionsFor the intervention group we redesigned care with a comprehensive 14–16 week multidisciplinary standardized clinical pathway, the Ochsner hip arthroplasty perioperative surgical home (PSH). Essential pathway components were preoperative medical risk assessment, frailty scoring, home assessment, education and expectation setting. Collaborative team-based care, rigorous application of perioperative milestones, and proactive postoperative care coordination were key elements.MeasurementsThe intervention group was compared to historical controls with regard to demographics, risk factors, quality metrics, resource utilization and discharge disposition, the primary outcomes were hospital length of stay and postacute facility utilization.Main resultsCompared to historical controls, the intervention group had similar risk factors and the same or better quality outcomes. It had less combined skilled nursing facility (SNF) and inpatient rehabilitation facility (IRF) utilization compared to controls (16.5% vs. 27.5%). More intervention patients were discharged with home self-care compared to historical controls (10.7% vs 5.3%). During the intervention period combined SNF/IRF utilization decreased substantially from 19.8% early on, to 13.2% during a later phase. Intervention patients had fewer hospital days compared to historical controls (1.86 vs 3.34 days, respectively; P < 0.0001).ConclusionsA perioperative population management oriented care model redesign was effective in decreasing hospital days and postacute facility-based care utilization, while quality metrics were maintained or improved.     

Impact of Hepatitis B virus infection on postoperative complications and length of stay in elderly patients with hip fracture: A retrospective cohort study

BackgroundOsteoporosis and subsequent fractures are common in the chronic hepatitis B (CHB) population, especially in the elderly. This study investigated the effects of hepatitis B virus (HBV) infection on postoperative outcomes following hip fracture surgery.MethodsThe study identified elderly patients who underwent hip fracture surgery at three academic tertiary care centres between January 2014 and December 2020. Propensity score matching was performed to compare the outcomes of 1,046 patients with HBV infection to 1,046 controls.ResultsThe seroprevalence of HBV among elderly patients undergoing hip surgery was 4.94%. The HBV cohort had significantly higher rates of medical complications (28.1 vs. 22.7%, p = 0.005), surgical complications (14.0 vs. 9.7%, p = 0.003), and unplanned readmissions (18.9 vs. 14.5%, p = 0.03) within 90 days of surgery. Patients with HBV infection were more likely to have increased length of stay (6.2 vs. 5.9 days, p = 0.009) and in-hospital charges (¥52,231 vs. ¥49,832, p < 0.00001). Multivariate logistic regression suggested that liver fibrosis and thrombocytopenia were independent risk factors for major complications and extended LOS.ConclusionPatients with HBV infection were at greater risk of adverse postoperative outcomes. We should pay more attention to the considerable burden of perioperative management of CHB patients. Due to the high proportion of undiagnosed patients in the Chinese elderly population, universal HBV screening should be considered preoperatively.
