Timing of complications following surgery for geriatric hip fractures

Comparison of patient demographics and patient-specific risk factors for readmissions following open reduction and internal fixation for acetabular fractures

PURPOSE

Acetabular fractures are highly complex injuries often resulting from high-energy trauma. The gold standard treatment for these injuries has become open reduction internal fixation (ORIF). The purpose of this study is to further this understanding and investigate how (1) patient demographics and (2) patient-specific risk factors affect 90-day readmission rates.

METHODS

A retrospective, nationwide query of private insurance database from January 1st, 2010 to October 31st, 2020 was performed using ICD-9, ICD-10, and CPT codes. Patients who underwent acetabular ORIF and were readmitted within 90 days following index procedure were included, patients who were not readmitted served as controls. Patients were divided by demographics and specific risk factors associated with readmission.

RESULTS

The query yielded a total of 3942 patients. Age and sex were found to be non-significant contributing risk factors to 90-day readmissions. Data also showed that statistically significant comorbidities included arrhythmia, cerebrovascular disease, coagulopathy, fluid and electrolyte abnormalities, and pathologic weight loss.

CONCLUSION

This study illustrated how several patient-specific risk factors may contribute to increased 90-day readmission risk following acetabular ORIF. A heightened awareness of these comorbidities in patients requiring acetabular ORIF is required to improve patient outcomes and minimize rates of readmission. Further investigation is needed to improve patient outcomes, and increase awareness of potential post-operative complications in these higher-risk patient populations.

Billing rules / global period affect postoperative follow-up practices following total hip arthroplasty

BACKGROUND

Total hip arthroplasty (THA) is a common procedure following which postoperative visits are important to optimize outcomes. The associated global billing period includes the 90 postoperative days (or approximately 13 weeks), during which professional billing is included with the surgery itself. The current study assessed clinical practice patterns relative to the global billing period.

METHODS

Using the PearlDiver M91Ortho dataset, the incidence and timing of Evaluation and Management (E&M) codes in the 26 weeks following THA were assessed. The follow-up visits within and beyond the global billing period, and those conducted by surgeons versus non-surgeon advanced practice providers (APPs) were determined.

RESULTS

77,843 THAs were identified. Follow-up visits peaked at postoperative weeks 3, 7, and 14. The greatest week-to-week variation in the number of follow-ups was from weeks 13 to 14 immediately following the global billing period (representing a greater than 4-fold increase in visits.) During the first 13 postop weeks, 73.8% of patients were seen by orthopedic surgeons (as opposed to APPs). In the following 13 weeks, a significantly greater percentage of visits were with surgeons (86.8%, p<0.0001).

CONCLUSIONS

Following the THA global billing period, there was marked increase in the number of follow-ups and transition to a greater percentage being performed by the surgeons. These results provide interesting insight into the potential impact of the billing structure on how practice is pursued.

Impact of fast-track rehabilitation nursing on pressure ulcers and postoperative complications in patients with inter-trochanteric fractures: A meta-analysis

We sought to investigate the effects of fast-track rehabilitation nursing on pressure ulcers, length of hospital stay and postoperative complications in patients with inter-trochanteric fractures (ITF). The PubMed, Web of Science, Embase, Cochrane Library, China National Knowledge Infrastructure and WanFang databases were searched for randomised controlled trials (RCTs) published from inception to September 2023 on the application of fast-track rehabilitative nursing to ITF. Two investigators independently screened the literature and performed data extraction and quality assessments using the Cochrane Risk of Bias Assessment Tool. The meta-analysis was performed using RevMan 5.4. Overall, 22 RCTs involving 1904 patients were included. Meta-analysis revealed that after fast-track rehabilitation nursing intervention in patients with ITF, the occurrence of pressure ulcers (odds ratio [OR]: 0.29; 95% confidence interval [CI]: 0.18-0.47; p < 0.001) and postoperative complications (OR: 0.19; 95% CI: 0.14-0.26; p < 0.001) were significantly reduced and hospital stay was significantly shorter (standardised mean difference: -3.10; 95% CI: -3.82 to -2.38; p < 0.001). Nursing care for patients with ITF based on the concept of fast-track rehabilitation is conducive to reducing the occurrence of pressure ulcers, lowering the occurrence of complications, shortening the length of hospitalisation and promoting postoperative rehabilitation.

The effect of smoking on 30-day complications following primary repair of Achilles tendon ruptures

PURPOSE

There exists a gap in the knowledge of the impact of smoking on Achilles tendon rupture repair. This study evaluates perioperative and postoperative complications associated with smoking to allow for a more informed evaluation and discussion with the patients when considering the surgical management of Achilles tendon repair in this patient population.

METHODS

The National Surgical Quality Improvement Program database was queried for patients undergoing Achilles tendon rupture repair from 2006 to 2019. Two patient cohorts were defined in this retrospective study: smokers and patients who did not smoke. The various patient demographics, medical comorbidities, and postoperative outcomes were compared using bivariate and multivariate analyses between the smoking and non-smoking groups.

RESULTS

Of 4209 patients who underwent Achilles tendon repair, 3662 patients (87%) did not smoke, whereas 547 patients (13%) were smokers. Patients who were smokers were more likely to be younger and have a higher body mass index. Following multivariate analyses, those who smoked had an increased risk of experiencing wound dehiscence (OR 3.57; p = 0.013) and urinary tract infections (OR 1.21; p = 0.033) compared to non-smoking patients.

CONCLUSION

Despite the rate of complications being relatively low in the short-term perioperative period, individuals who smoke should be counseled on the surgical risks they may experience following Achilles tendon repair, including wound dehiscence and urinary tract infections. Discussion preoperatively between the physician and patient who smoke can include ways in which postoperative care will be done to minimize the risk of adverse events, ultimately reducing costs for both the patient and the hospital.

Enhancing Surgical Outcomes: A Critical Review of Antibiotic Prophylaxis in Orthopedic Surgery

The postoperative burden remains significant due to the possibility of prolonged hospitalization, escalated healthcare costs, and patient distress caused by postorthopedic surgical site infections (SSIs). Orthopedic surgery is likewise faced with a significant challenge posed by these conditions. A positive association has been observed between the presence of postorthopedic SSIs and heightened susceptibility to adverse health outcomes, along with elevated rates of morbidity and mortality. Systemic antibiotic prophylaxis (SAP) reduces the risk of acquiring an SSI. Closed fractures, open fractures, arthroplasty, and percutaneous fixation each possess distinct attributes that impact the data and antimicrobial therapy. When implementing SAP, it is crucial to strike a delicate equilibrium between maintaining effective antibiotic stewardship protocols and preventing the occurrence of SSIs. This practice effectively prevents both the incidence of negative consequences and the emergence of antibiotic resistance. The objective of this study was to examine the existing literature on the use of surgical antibiotic prophylaxis in orthopedic surgery and explore the potential consequences associated with the inappropriate administration of antibiotics.

Timing of Complications Following Surgery for Distal Femur Fractures in Older Adults

Introduction

The purpose of this study was to identify the timing and nature of complications associated with distal femur fracture surgery in patients aged 65 and older using the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database.

Methods

The ACS NSQIP database was queried for adults aged 65 and older who received surgical treatment for a distal femur fracture between 01 January 2015 and 31 December 2021. Cox regression models and risk tables adjusted for baseline clinical characteristics were created for 14 complications (Superficial Surgical Site Infection (SSI), Deep SSI, Organ/Space SSI, Pneumonia, Pulmonary Embolism (PE), Deep Venous Thrombosis (DVT), Urinary Tract Infection (UTI), Stroke/Cerebrovascular accident (CVA), Myocardial Infarction (MI), Renal Failure, Cardiac Arrest (CA), Re-operation, Sepsis, and Death within 30 days of surgery). Model summaries were used to identify significant variables with a Bonferroni correction applied.

Results

A total of 3956 adults met inclusion criteria and were included in analysis. The most common complications were UTI (5.2%), death (4.1%), and pneumonia (3.4%). Complications typically occurred within 14 days after surgery, except for SSI, which occurred between post-op days 11 and 24.

Conclusions

Distal femur fractures are a substantial source of morbidity and mortality in the older adult population. Our findings underscore the need for comprehensive preoperative risk assessment and patient management strategies to mitigate the impact of identified risk factors in this vulnerable population.

Timing of venous thromboemboli in patients with acetabular and pelvic ring fractures

PURPOSE

To determine the timing of symptomatic venous thromboemboli (VTE) in patients sustaining a pelvic and/or acetabular fracture. Secondly, to evaluate for any factors that may influence this timing.

METHODS

A retrospective cohort of 47 patients with acetabular and/or pelvic ring injuries who developed VTEs at a single academic level I trauma center were identified from 2012 to 2018. The chronology of VTE diagnosis in relation to date of injury, initial surgery, final surgery, and date of discharge was evaluated. Patients who developed VTEs were then evaluated based on known risk factors for VTE to determine if any of these affected timing.

RESULTS

Symptomatic VTEs were diagnosed in 3.8% of patients with pelvic and/or acetabular fractures. In patients who developed a thromboembolism, diagnosis occurred on average 21.5 (± 19.2), 20.7 (± 19.9), 9.8 (± 23.4), and 4.3 (± 27.6) days after injury, index procedure, final procedure, and date of discharge. 25% of patients developed VTE more than 4 weeks after their initial injury. No known risk factors effected the timing of VTE.

CONCLUSION

The 2015 OTA expert panel recommends 4 weeks of anticoagulation for orthopedic trauma patients at high risk of VTE, which may be too short a duration. In our cohort, 25% of VTEs occurred greater than 4 weeks after injury. Additional research is needed to clarify the exact duration of anticoagulation after pelvic and acetabular fractures; however, surgeons may want to consider anticoagulating patients for greater than 4 weeks.

Timing of adverse events in patients undergoing acute and elective hip arthroplasty surgery: a multicentre cohort study using the Global Trigger Tool

OBJECTIVE

To explore timing in relation to all types of adverse events (AEs), severity and preventability for patients undergoing acute and elective hip arthroplasty.

DESIGN

A multicentre cohort study using retrospective record review with Global Trigger Tool methodology in combination with data from several registers.

SETTING

24 hospitals in 4 major regions of Sweden.

PARTICIPANTS

Patients ≥18 years, undergoing acute or elective total or hemiarthroplasty of the hip, were eligible for inclusion. Reviews of weighted samples of 1998 randomly selected patient records were carried out using Global Trigger Tool methodology. The patients were followed for readmissions up to 90 days postoperatively throughout the whole country.

RESULTS

The cohort consisted of 667 acute and 1331 elective patients. Most AEs occurred perioperatively and postoperatively (n=2093, 99.1%) and after discharge (n=1142, 54.1%). The median time from the day of surgery to the occurrence of AE was 8 days. The median days for different AE types ranged from 0 to 24.5 for acute and 0 to 71 for elective patients and peaked during different time periods. 40.2% of the AEs, both major and minor, occurred within postoperative days 0-5 and 86.9% of the AEs occurred within 30 days. Most of the AEs were deemed to be of major severity (n=1370, 65.5%) or preventable (n=1591, 76%).

CONCLUSIONS

A wide variability was found regarding the timing of different AEs with the majority occurring within 30 days. The timing and preventability varied regarding the severity. Most of the AEs were deemed to be preventable and/or of major severity. To increase patient safety for patients undergoing hip arthroplasty surgery, a better understanding of the multifaceted nature of the timing of AEs in relation to the occurrence of differing AEs is needed.

Postoperative awake prone position in geriatric patients with hip fractures: a protocol for a randomized controlled trial on the efficacy of postoperative prone position in reducing pulmonary complications and improving oxygenation

INTRODUCTION

Postoperative pulmonary complications (PPCs) are prevalent in geriatric patients with hip fractures. Low oxygen level is one of the most important risk factors for PPCs. Prone position has been proven efficacy in improving oxygenation and delaying the progress of pulmonary diseases, especially in patients with acute respiratory distress syndrome induced by multiple etiologies. The application of awake prone position (APP) has also attracted widespread attention in recent years. A randomized controlled trial (RCT) will be carried out to measure the effect of postoperative APP in a population of geriatric patients undergoing hip fracture surgery.

METHODS

This is an RCT. Patients older than 65 years old admitted through the emergency department and diagnosed with an intertrochanteric or femoral neck fracture will be eligible for enrollment and assigned randomly to the control group with routine postoperative management of orthopedics or APP group with an additional prone position for the first three consecutive postoperative days (PODs). Patients receiving conservative treatment will not be eligible for enrollment. We will record the difference in the patient's room-air-breathing arterial partial pressure of oxygen (PaO₂) values between the 4^th POD (POD 4) and emergency visits, the morbidity of PPCs and other postoperative complications, and length of stay. The incidence of PPCs, readmission rates, and mortality rates will be followed up for 90 PODs.

DISCUSSION

We describe the protocol for a single-center RCT that will evaluate the efficacy of postoperative APP treatment in reducing pulmonary complications and improving oxygenation in geriatric patients with hip fractures.

ETHICS AND DISSEMINATION

This protocol was approved by the independent ethics committee (IEC) for Clinical Research of Zhongda Hospital, Affiliated to Southeast University, and is registered on the Chinese Clinical Trial Registry. The findings of the trial will be disseminated through peer-reviewed journals.

Timing of Adverse Events Within 90 Days of Hip Fracture Surgery: A Database Study

INTRODUCTION

Hip fracture surgery is associated with notable morbidity. Understanding the timing of adverse events can inform strategies for prevention and management. Owing to database limitations, many studies have limited postoperative follow-up to 30 days. However, adverse events may not have plateaued by this time. This study evaluated adverse events after hip fracture surgery out to 90 days.

METHODS

Hip fracture surgeries in patients 65 years or older were identified in the 2010 to 2020 Q3 M91Ortho PearlDiver data set using administrative codes. The 90-day incidence and time of diagnosis of 10 common adverse events were determined and used to calculate median, interquartile range, and middle 80% for time of diagnosis. The number of events occurring before and after 30 days was also determined.

RESULTS

A total of 258,834 hip fracture surgery patients were identified. On average, 70% of adverse events occurred in postoperative days 0 to 30 and 30% occurred in days 31 to 90. The percentage of events in days 31 to 90 ranged from 8% (transfusion) to 42% (wound dehiscence). Compared with patients with a 0- to 30-day adverse event, those with 31- to 90-day adverse events had higher average Elixhauser Comorbidity Index scores (8.6 vs. 7.8, P < 0.001) and a slightly greater proportion of men (31.5% vs. 30.2%, P < 0.001).For specific adverse events, the time of diagnosis (median; interquartile range; middle 80%) were as follows: transfusion (2 days; 1 to 4 days; 1 to 24 days), acute kidney injury (5; 2 to 26; 1 to 55), cardiac event (9; 3 to 35; 1 to 64), urinary tract infection (13; 3 to 39; 1 to 65), hematoma (14; 6 to 28; 3 to 52), pneumonia (15; 5 to 39; 2 to 66), venous thromboembolism (16; 5 to 40; 2 to 64), surgical site infection (23; 14 to 37; 7 to 56), sepsis (24; 9 to 48; 3 to 71), and wound dehiscence (26; 15 to 41; 7 to 64).

DISCUSSION

Nearly one-third of 90-day adverse events after hip fracture surgery were found to occur after postoperative day 30. An understanding of the timing of adverse events is important for improving patient counseling and optimizing patient care.

Determination of risk factors of postoperative pneumonia in elderly patients with hip fracture: What can we do?

Background

Postoperative pneumonia is a serious complication in elderly patients with hip fracture. It is necessary to identify the influencing factors of postoperative pneumonia in patients with hip fracture.

Methods

Elderly patients with hip fractures admitted to a tertiary hospital in China from January 1, 2020 to August 31, 2021 were included. The characteristics of patients with and without postoperative pneumonia were evaluated and compared. Logistic multivariate regression analyses were conducted to assess the risk factors of postoperative pneumonia.

Results

267 patients with hip fracture were included, the incidence of postoperative pneumonia in patients with hip fracture was 13.11%. There were significant differences in the age, diabetes mellitus, anemia, hypoalbuminemia, anesthesia method and duration of surgery between infection and no infection group, no significant differences in the gender, BMI, hypertension, hyperlipidemia, type of fracture, preoperative oxygen saturation, white blood cell count, platelet count, red blood cell count, creatinine, alanine aminotransferase, aspartate aminotransferase, estimated blood loss during surgery were detected between infection and no infection group. Logistic regression analysis showed that age≥70y (OR2.326, 95%CI1.248~3.129), diabetes mellitus (OR2.123, 95%CI1.021~3.551), anemia (OR3.199,95%CI1.943~5.024), hypoalbuminemia (OR2.377, 95%CI1.211~3.398), general anesthesia (OR1.947, 95%CI1.115~3.038), duration of surgery≥120min (OR1.621, 95%CI1.488~2.534) were the risk factors of postoperative pneumonia in elderly patients with hip fracture (all p<0.05). Escherichia Coli (33.33%), Klebsiella pneumoniae (28.57%), Staphylococcus aureus (21.43%) were the most common bacteria of pulmonary infection.

Conclusion

There are many risk factors for postoperative pneumonia in elderly patients with hip fractures after surgery. In clinical practice, medical workers should take targeted interventions for those risk factors to reduce postoperative pneumonia.

Surgical-site infection after hip fracture surgery: preoperative full-body disinfection compared to local disinfection of the surgical site-a population-based observational cohort study

Aim

To compare preoperative full-body disinfection (FBD) prior to hip fracture surgery with local disinfection (LD) of the surgical site regarding incidence of postoperative surgical-site infection (SSI), both procedures performed with 4% chlorhexidine.

Findings

There were 16 (6.8%) cases of SSI in 2018 when FBD was performed and 8 (3.1%) cases in 2019 when LD was performed. FBD (2018) compared to LD (2019) presented an adjusted OR of 2.0 (95% CI 0.8–5.1) in the logistic regression analysis.

Message

Results suggest that LD is not inferior to FBD regarding SSI prevention, meaning patients could potentially be spared significant levels of pain caused by FBD.

Purpose

Swedish national guidelines recommend full-body disinfection (FBD) with 4% chlorhexidine before hip fracture surgery to prevent surgical-site infection (SSI) despite little evidence. Our objective was to compare preoperative FBD with local disinfection (LD) of the surgical site regarding SSI incidence.

Methods

All patients with hip fracture, operated at a hospital in Sweden, January 1, 2018 to December 31, 2019 were included. Patients in 2018 (n = 237) were prepared with FBD and patients in 2019 (n = 259) with LD. Primary outcome was SSI and secondary outcome was SSI and/or death. We adjusted for potential confounders with logistic regression. The adjusted analysis was performed in two models to enable assessment of variables that lacked either outcome; in the first model, these variables were not adjusted, and the second model was restricted to a sub-population not affected by respective variables.

Results

There were 16 (6.8%) cases of SSI in 2018 and 8 (3.1%) cases in 2019. FBD (2018) compared to LD (2019) presented an adjusted OR of 1.9 (95%CI 0.8–4.9, P = 0.16) respectively 2.0 (95%CI 0.8–5.1, P = 0.14) in the two models of the logistic regression. In addition, 40 (16.9%) patients in 2018 and 29 (11.2%) patients in 2019 had the combined outcome of SSI and/or death, adjusted OR 1.6 (95% CI 0.9–2.8, P = 0.08) respectively 1.7 (95% CI 0.9–2.9, P = 0.06).

Conclusion

We found a non-significant increased risk of SSI 2018 compared to 2019 after adjustment. Randomized control trials are needed. Nonetheless, results suggest that LD is not inferior to FBD regarding SSI prevention, meaning patients could potentially be spared substantial pain.

Effect of Antimicrobial Prophylaxis Duration on Health Care-Associated Infections After Clean Orthopedic Surgery: A Cluster Randomized Trial

IMPORTANCE

Postoperative health care-associated infections are associated with a greater deterioration in patients' general health status and social and economic burden, with at least 1 occurring in approximately 4% of acute care hospital patients. Antimicrobial prophylaxis prevents surgical site infections in various orthopedic procedures; however, its relationship with health care-associated infections remains unknown.

OBJECTIVE

To examine whether a shorter antimicrobial prophylaxis duration of less than 24 hours after surgery is not inferior to a longer duration in preventing health care-associated infections after clean orthopedic surgery.

DESIGN, SETTING, AND PARTICIPANTS

This open-label, multicenter, cluster randomized, noninferiority clinical trial was conducted in 5 tertiary referral hospitals in greater Tokyo metropolitan area, Japan, from May to December 2018. Adult patients undergoing clean orthopedic surgery were recruited until the planned number of participants was achieved (500 participants per group). Statistical analysis was conducted from July to December 2019.

INTERVENTIONS

Antimicrobial prophylaxis was discontinued within 24 hours after surgery in group 24 and 24 to 48 hours after surgery in group 48. Group allocation was switched every 2 or 4 months according to the facility-based cluster rule. Study-group assignments were masked from participants.

MAIN OUTCOMES AND MEASURES

The primary outcome was the incidence of health care-associated infections requiring antibiotic therapies within 30 days after surgery. The noninferiority margin was 4%.

RESULTS

Of the 1211 participants who underwent cluster allocation, 633 participants were in group 24 (median [IQR] age, 73 [61-80] years; 250 men [39.5%] and 383 women [60.5%]), 578 participants were in group 48 (median [IQR] age, 74 [62-81] years; 204 men [35.3%] and 374 women [64.7%]), and all were eligible for the intention-to-treat analyses. Health care-associated infections occurred in 29 patients (4.6%) in group 24 and 38 patients (6.6%) in group 48. Intention-to-treat analyses showed a risk difference of -1.99 percentage points (95% CI, -5.05 to 1.06 percentage points; P < .001 for noninferiority) between groups, indicating noninferiority. Results of adjusted intention-to-treat, per-protocol, and per designated procedure population analyses supported this result, without a risk of antibiotic resistance and prolonged hospitalization.

CONCLUSIONS AND RELEVANCE

This cluster randomized trial found noninferiority of a shorter antimicrobial prophylaxis duration in preventing health care-associated infections without an increase in antibiotic resistance risk. These findings lend support to the global movement against antimicrobial resistance and provide additional information on adequate antimicrobial prophylaxis for clean orthopedic surgery.

A Case-Control Study of Hip Fracture Surgery Timing and Mortality at an Academic Hospital: Day Surgery May Be Safer than Night Surgery

Time from hospital admission to operative intervention has been consistently demonstrated to have a significant impact on mortality. Nonetheless, the relationship between operative start time (day versus night) and associated mortality has not been thoroughly investigated. Methods: All patients who underwent hip fracture surgery at a single academic institution were retrospectively analyzed. Operative start times were dichotomized: (1) day operation—7 a.m. to 4 p.m.; (2) night operation—4 p.m. to 7 a.m. Outcomes between the two groups were evaluated. Results: Overall, 170 patients were included in this study. The average admission to operating room (OR) time was 26.0 ± 18.0 h, and 71.2% of cases were performed as a day operation. The overall 90-day mortality rate was 7.1% and was significantly higher for night operations (18.4% vs. 2.5%; p = 0.001). Following multivariable logistic regression analysis, only night operations were independently associated with 90-day mortality (aOR 8.91, 95% confidence interval 2.19–33.22; p = 0.002). Moreover, these patients were significantly more likely to return to the hospital within 50 days (34.7% vs. 19.0%; p = 0.029) and experience mortality prior to discharge (8.2% vs. 0.8%; p = 0.025). Notably, admission to OR time was not associated with in-hospital mortality (29.22 vs. 25.90 h; p = 0.685). Hip fracture surgery during daytime operative hours may minimize mortalities.

Impact of right ventricular systolic pressure in elderly patients admitted to intensive care unit after femur fracture surgery: A retrospective observational study

The number of femoral fractures is expected to continue to increase as the size of the older population rapidly grows. However, old age is accompanied by various comorbidities and is an important postoperative risk factor in itself, meaning that patients who undergo surgery for a femur fracture may require admission to an ICU. We investigated pulmonary complications in patients over the age of 65 admitted to the ICU after femur fracture surgery.In this single-center retrospective observational study, 289 patients over 65 years who admitted to the ICU after femur fracture surgery between June 2008 and December 2016 were investigated.Pulmonary complications occurred in 97 of these patients (33.6%) after surgery. Mean hospitalization days (34.1 ± 25.7 vs 23.1 ± 15.7, P < .001) and mean ICU length of stay (8.4 ± 16.1 vs 2.5 ± 1.1, P = .001) were significantly longer for patients with pulmonary complications than for patients without pulmonary complications after femur fracture surgery. Patients with pulmonary complications were significantly more likely to have pulmonary disease (19.6% vs 8.9%, P = .009) and exhibit sequelae on preoperative chest X-rays (9.3% vs 3.6%, P = .048) than were patients without pulmonary complications. In addition, significant differences were observed in the right ventricular systolic pressure (RVSP) measured during preoperative echocardiography (37.4 ± 10.9 mm Hg vs 40.7 ± 9.3 mm Hg for patients without and with pulmonary complications, P = .010) and in the proportion of each group that had an RVSP of >35 mm Hg, which is a marker for pulmonary hypertension (55.2% vs 76.3% for patients without and with pulmonary complications, P < .001). In multivariate analysis, an RVSP of >35 mm Hg during preoperative echocardiography was associated with pulmonary complications after femur fracture surgery (OR, 2.6; 95% CI, 1.45-4.53).In conclusion, Pulmonary complications in older patients admitted to the ICU after femur fracture surgery was associated with longer hospitalization and ICU stays. Preoperative RVSP measurement could identify those older patients with a high risk of pulmonary complications following transferal to the ICU after femur fracture surgery.

Length of stay and contributing factors in elderly patients who have undergone hip fracture surgery in a tertiary hospital in South Africa

BACKGROUND

Length of stay and factors that contribute to length of stay in elderly patients who have undergone hip fracture surgery is under researched in developing countries, including South Africa. The purpose of this study was to describe the factors that increase length of stay (LOS) among elderly patients who have had hip fracture surgery.

METHODS

A retrospective review of patient records of elderly (>65 years) patients who had hip fracture surgery in a public hospital in South Africa. Descriptive statistics were used to report demographic data, LOS and frequency distributions of individual factors relating to LOS. Two sample t-tests were used to compare the LOS in patients with and without main complications reported.

RESULTS

The mean total length of stay was 33 (19) days. Patients presented with numerous comorbidities, with hypertension (n = 93) being the most prevalent. The most frequently occurring complications included anaemia (n = 42) and wound infection (n = 21). The LOS was significantly lower for patients not presenting with wound infections compared to those who sustained a wound infection (p = 0.041). Social factors delayed departure from the hospital for 48 patients.

CONCLUSION

Elderly patients who had hip fracture surgery and developed wound infections had an increased LOS. However social issues also contributed to the increase in length of stay that could be addressed by proper planning and involvement of families and care givers. The factors identified could be used as a starting point for planning services aimed at decreasing the hospital stay of elderly patients.
