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 4th 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. ETHICS APPROVAL NUMBER: 2021ZDSYLL203-P01 TRIAL REGISTRATION: ChiCTR ChiCTR2100049311 . Registered on 29 July 2021.

The Impact of COVID-19 on the Prevalence, Mortality, and Associated Risk Factors for Mortality in Patients with Hip Fractures: A Meta-Analysis.

OBJECTIVE: This study aimed to assess (1) the prevalence of COVID-19 in patients with hip fracture; (2) the mortality rate of patients with hip fracture associated with COVID-19; (3) risk factors associated with mortality in patients with hip fracture; and (4) the effects of COVID-19 on surgical outcomes of patients with hip fracture. DESIGN: Meta-analysis. SETTING AND PARTICIPANTS: Patients with hip fractures during COVID-19. METHODS: PubMed, Web of Science, and Embase were systematically reviewed. The outcomes included the prevalence of COVID-19, case fatality rate, 30-day mortality, cause of death, risk factors associated with the mortality of patients with hip fracture, time to surgery, surgical time, and length of hospitalization. Risk ratio or weight mean difference with 95% confidence intervals were used to pool the estimates. RESULTS: A total of 60 studies were included in this meta-analysis. The pooled estimate showed that the prevalence of COVID-19 was 21% in patents with hip fractures. Patients with hip fracture with COVID-19 had an increased 30-day mortality risk compared with those without the infection. The main causes of death were respiratory failure, COVID-19-associated pneumonia, multiorgan failure, and non-COVID-19 pneumonia. The hospitalization was longer in patients with COVID-19 when compared with those without the infection, but was shorter in patients during the pandemic period. The surgery time and time to surgery were not significantly different between patients during or before the pandemic period and in those with or without COVID-19. CONCLUSIONS AND IMPLICATIONS: The 30-day mortality rate was significantly higher in patients with hip fracture with COVID-19 infection than those without. Patients with COVID-19 had a higher all-cause mortality rate than those without. This information can be used by the medical community to guide the management of patients with hip fracture with COVID-19.

Complex organisational factors influence multidisciplinary care for patients with hip fractures: a qualitative study of barriers and facilitators to service delivery.

BACKGROUND: Hip fractures are devastating injuries, with high health and social care costs. Despite national standards and guidelines, substantial variation persists in hospital delivery of hip fracture care and patient outcomes. This qualitative study aimed to identify organisational processes that can be targeted to reduce variation in service provision and improve patient care. METHODS: Interviews were conducted with 40 staff delivering hip fracture care in four UK hospitals. Twenty-three anonymised British Orthopaedic Association reports addressing under-performing hip fracture services were analysed. Following Thematic Analysis of both data sources, themes were transposed onto domains both along and across the hip fracture care pathway. RESULTS: Effective pre-operative care required early alert of patient admission and the availability of staff in emergency departments to undertake assessments, investigations and administer analgesia. Coordinated decision-making between medical and surgical teams regarding surgery was key, with strategies to ensure flexible but efficient trauma lists. Orthogeriatric services were central to effective service delivery, with collaborative working and supervision of junior doctors, specialist nurses and therapists. Information sharing via multidisciplinary meetings was facilitated by joined up information and technology systems. Service provision was improved by embedding hip fracture pathway documents in induction and training and ensuring their consistent use by the whole team. Hospital executive leadership was important in prioritising hip fracture care and advocating service improvement. Nominated specialty leads, who jointly owned the pathway and met regularly, actively steered services and regularly monitored performance, investigating lapses and consistently feeding back to the multidisciplinary team. CONCLUSION: Findings highlight the importance of representation from all teams and departments involved in the multidisciplinary care pathway, to deliver integrated hip fracture care. Complex, potentially modifiable, barriers and facilitators to care delivery were identified, informing recommendations to improve effective hip fracture care delivery, and assist hospital services when re-designing and implementing service improvements.

[Translated article] Has the COVID-19 lockdown influenced the mortality of hip fracture? Analysis of one-year mortality.

INTRODUCTION AND OBJECTIVES: The main objective of this study is to analyse the one-year mortality in patients with intracapsular hip fracture who were admitted during severe social confinement in the first months of the COVID-19 lockdown and compare it with previous years. MATERIAL AND METHODS: Retrospective observational study in which a cohort from March 14 to June 21, 2020 (pandemic group, n=62) was compared with a control cohort on the same dates in the years 2017, 2018 and 2019 (control group, n=172). Thirty-day-mortality and one-year-mortality, orthopaedic complications, ASA grade, comorbidities, diagnosis and treatment, time to surgery and mean stay were measured. RESULTS: No significant differences were found in 30-day mortality (p=0.156; 9.7% compared to 4.7%) or in one-year mortality (p=0.47) between the pandemic group (21%) and the control one (16.9%). A decrease in surgical delay and mean stay was observed in the pandemic group, although without statistical significance. CONCLUSION: The State of Alarm modified the distribution of the type of hip fracture with a predominance of intracapsular fracture. Maintaining the same hospital management as prior to the pandemic period made it possible not to increase 30-day mortality and one-year mortality in patients with intracapsular hip fracture.

Have mortality rates in elderly patients with hip fractures changed during pandemic?

OBJECTIVE: The mortality rates of patients over 65 years suffering from hip fractures were compared with/without infection related to SARS-CoV-2 virus during the 3 years of the pandemic. PATIENTS AND METHODS: Patients with femoral proximal region fracture (Type A-B) over 65 years were searched between January 2019 and February 2021 retrospectively. 487 patients met the inclusion criteria and were classified as Group I for surgery before and Group 2 for surgery during the pandemic. Demographic characteristics of the groups, hospitalization time before surgery, hospitalization total time, post-operative time until death and mortality rates were analyzed. RESULTS: The survival rate of hip fracture patients over 65 was higher for the surgeries performed during the pandemic compared to Group I (p=0.032). Patients with 2, 3 or 4 comorbidities in Group I had higher mortality rates (p<0.05). According to fracture type, the mortality rates were higher in Group I (patients with femoral neck fractures) (p=0.005), in contrast mortality rate for trochanteric fractures (p>0.05) remained the same. Mortality rates of Group I and II did not differ according to either time from admission to operation, or time to surgery for fracture types. The mortality rates at 1, 4, 12, and 24 months were determined to be 8.83%, 20.14%, 36.75%, and 45.22%, respectively in Group I, and 8.86%, 23.15%, 32.51%, and 33.49% in Group II with no difference. CONCLUSIONS: The approaches taken in extraordinary circumstances such as a pandemic can change the course or outcomes of a disease. These changes may emerge as different mortality rates between periods of time. Further studies to lower mortality rates depending on hip fracture are warranted especially for patients over 65.

Reduction of early surgical site and other care related infections in 3553 hip fracture patients: lessons learned from the 5-year Safe Hands project.

BACKGROUND: Surgical site infection (SSI) after acute hip fracture surgery is a devastating complication associated with increased suffering and mortality. The aim of the study was to investigate early SSI, sepsis, pneumonia and urinary tract infections over five years, before and after the implementation of the Safe Hands project. METHODS: This was a single-centre observational study with a 5-year longitudinal design, investigating the effects of an infection-prevention intervention targeting the clinical care pathway of individuals with acute hip fracture. Statistical analyses were based on routinely collected patient outcome data comprising 3553 patients. The study conforms to the criteria of the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE). RESULTS: The incidence of early SSIs decreased from 2.5% in years 1-2 to 1.1% in years 4-5. Similar results were observed for sepsis (2.7% to 1.3%) and urinary tract infections (14.2% to 4.2%). The multivariable regression results suggest that, for every observed year, the odds of early SSIs decreased. Male gender, procedure time, sepsis and preoperative skin damage increased the odds significantly. CONCLUSIONS: Our preventive bundle, based on partnership between researchers, managers and clinicians and a strong commitment to change from the involved professions, appear to be effective in reducing the frequency of potentially devastating SSIs and other hospital acquired infections after hip fracture surgery. The use of external and internal facilitators was crucial to enable individual and organisational learning and overcoming barriers to improvements.

IMPACT of COVID-19 on hip fracture services: A global survey by the International Multicentre Project Auditing COVID-19 in Trauma & Orthopaedics.

INTRODUCTION: The Coronavirus Disease 2019 (COVID-19) pandemic resulted in major disruption to hip fracture services. This frail patient group requires specialist care, and disruption to services is likely to result in increases in morbidity, mortality and long-term healthcare costs. AIMS: To assess disruption to hip fracture services during the COVID-19 pandemic. METHODS: A questionnaire was designed for completion by a senior clinician or service manager in each participating unit between April-September 2020. The survey was incorporated into existing national-level audits in Germany (n = 71), Scotland (n = 16), and Ireland (n = 16). Responses from a further 82 units in 11 nations were obtained via an online survey. RESULTS: There were 185 units from 14 countries that returned the survey. 102/160 (63.7%) units reported a worsening of overall service quality, which was attributed predominantly to staff redistribution, reallocation of inpatient areas, and reduced access to surgical facilities. There was a high rate of redeployment of staff to other services: two thirds lost specialist orthopaedic nurses, a third lost orthogeriatrics services, and a quarter lost physiotherapists. Reallocation of inpatient areas resulted in patients being managed by non-specialised teams in generic wards, which increased transit of patients and staff between clinical areas. There was reduced operating department access, with 74/160 (46.2%) centres reporting a >50% reduction. Reduced theatre efficiency was reported by 135/160 (84.4%) and was attributed to staff and resource redistribution, longer anaesthetic and transfer times, and delays for preoperative COVID-19 testing and using personal protective equipment (PPE). CONCLUSION: Hip fracture services were disrupted during the COVID-19 pandemic and this may have a sustained impact on health and social care. Protection of hip fracture services is essential to ensure satisfactory outcomes for this vulnerable patient group.

Risk factors for postoperative medical morbidity and 3-month mortality in elderly patients with hip fracture following hip arthroplasty during COVID-19 pandemic.

BACKGROUND: The purpose of the current study was to investigate the incidence of postoperative medical complications and 3-month mortality in patients ≥ 70 years old with hip fracture following hip arthroplasty (HA) and independent risk factors associated with postoperative medical complications and 3-month mortality during the Coronavirus Disease 2019 (COVID-19) pandemic. METHODS: A multicenter retrospective study was conducted, patients ≥ 70 years old with HA for hip fracture under general anesthesia were included during COVID-19 and before COVID-19 pandemic. The outcome was defined as postoperative medical complications and 3-month mortality. The baseline characteristics and risk factors were collected, multivariable logistic regression was used to identify independent risk factors for postoperative medical complications and 3-month mortality. RESULTS: A total of 1096 patients were included during COVID-19 pandemic and 1149 were included before COVID-19 pandemic in the study. Patients ≥ 70 years with hip fracture for HA had longer fracture to operation duration (7.10 ± 3.52 vs. 5.31 ± 1.29, P < 0.001), and the incidence of postoperative medical complications (21.90% vs. 12.53%, P < 0.001) and 3-month mortality (5.20% vs. 3.22%, P = 0.025) was higher during COVID-2019 pandemic. Multivariate logistic regression analysis showed that dementia (OR 2.73; 95% CI 1.37-5.44; P = 0.004), chronic obstructive pulmonary disease (COPD) (OR 3.00; 95% CI 1.92-4.71; P < 0.001), longer fracture to operation duration (OR 1.24; 95% CI 1.19-1.30; P < 0.001) were associated with increased risk for postoperative medical complications. COPD (OR 2.10; 95% CI 1.05-4.17; P = 0.035), dementia (OR 3.00; 95% CI 1.11-7.94; P = 0.031), postoperative medical complications (OR 4.99; 95% CI 2.68-9.28; P < 0.001), longer fracture to operation duration (OR 1.11; 95% CI 1.04-1.19; P = 0.002) were associated with increased risk for 3-month mortality. CONCLUSIONS: In conclusion, we found that postoperative medical morbidity and 3-month mortality in patients with hip fracture underwent HA were 21.90% and 5.20%, respectively, during the COVID-19. COPD, dementia and longer fracture to operation duration were associated with negative outcome in patients with hip fracture underwent HA during the COVID-19.

The impact of COVID-19 on mortality after hip fracture : a population cohort study from England.

AIMS: Hip fracture commonly affects the frailest patients, of whom many are care-dependent, with a disproportionate risk of contracting COVID-19. We examined the impact of COVID-19 infection on hip fracture mortality in England. METHODS: We conducted a cohort study of patients with hip fracture recorded in the National Hip Fracture Database between 1 February 2019 and 31 October 2020 in England. Data were linked to Hospital Episode Statistics to quantify patient characteristics and comorbidities, Office for National Statistics mortality data, and Public Health England's SARS-CoV-2 testing results. Multivariable Cox regression examined determinants of 90-day mortality. Excess mortality attributable to COVID-19 was quantified using Quasi-Poisson models. RESULTS: Analysis of 102,900 hip fractures (42,630 occurring during the pandemic) revealed that among those with COVID-19 infection at presentation (n = 1,120) there was a doubling of 90-day mortality; hazard ratio (HR) 2.09 (95% confidence interval (CI) 1.89 to 2.31), while the HR for infections arising between eight and 30 days after presentation (n = 1,644) the figure was greater at 2.51 (95% CI 2.31 to 2.73). Malnutrition (1.45 (95% CI 1.19 to 1.77)) and nonoperative treatment (2.94 (95% CI 2.18 to 3.95)) were the only modifiable risk factors for death in COVID-19-positive patients. Patients who had tested positive for COVID-19 more than two weeks prior to hip fracture initially had better survival compared to those who contracted COVID-19 around the time of their hip fracture; however, survival rapidly declined and by 365 days the combination of hip fracture and COVID-19 infection was associated with a 50% mortality rate. Between 1 January and 30 June 2020, 1,273 (99.7% CI 1,077 to 1,465) excess deaths occurred within 90 days of hip fracture, representing an excess mortality of 23% (99.7% CI 20% to 26%), with most deaths occurring within 30 days. CONCLUSION: COVID-19 infection more than doubles the rate of early hip fracture mortality. Those contracting infection between 8 and 30 days after initial presentation are at even higher mortality risk, signalling the potential for targeted interventions during this period to improve survival.Cite this article: Bone Joint J 2022;104-B(10):1156-1167.

Proximal Femoral Fractures in the Elderly: A Few Things to Know, and Some to Forget.

Hip fractures are a leading cause of hospitalisation in elderly patients, representing an increasing socioeconomic problem arising from demographic changes, considering the increased number of elderly people in our countries. Adequate peri-operative treatment is essential to decrease mortality rates and avoid complications. Modern management should involve a coordinated multidisciplinary approach, early surgery, pain treatment, balanced fluid therapy, and prevention of delirium, to improve patients' functional and clinical outcomes. The operative treatment for intertrochanteric and subtrochanteric fractures is intramedullary nail or sliding/dynamic hip screw (DHS) on the basis of the morphology of the fracture. In the case of neck fractures, total hip replacement (THR) or hemiarthroplasty are recommended. However, several topics remain debated, such as the optimum thromboprophylaxis to reduce venous thromboembolism or the use of bone cement. Postoperatively, patients can benefit from early mobilisation and geriatric multidisciplinary care. However, during the COVID-19 pandemic, a prolonged time to operation with a subsequent increased complication rate have burdened frail and elderly patients with hip fractures. Future studies are needed with the aim to investigate better strategies to improve nutrition, postoperative mobility, to clarify the role of home-based rehabilitation, and to identify the ideal analgesic treatment and adequate tools in case of patients with cognitive impairment.

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 treatment for fragility hip fractures during the COVID-19 pandemic resulted in lower short-term postoperative functional outcome and a higher complication rate compared to the pre-pandemic period.

The COVID-19 pandemic adversely affected the functional outcomes of fragility hip fracture patients. This study revealed a higher in-hospital complication rate and lower postoperative function at 3 months among patients treated during the pandemic. Therefore, modified in-hospital and post-discharge protocols should be developed for implementation during pandemic crisis periods. INTRODUCTION: This study aims to investigate the in-hospital complication rate and short-term postoperative functional outcomes of fragility hip fracture (FHF) patients compared between during the COVID-19 pandemic and the same 14-month time period 1 year prior to the pandemic. METHODS: Using data from the Siriraj Fracture Liaison Service registry, FHF patients treated during the COVID-19 pandemic (1 March 2020 to 30 April 2021) were time-matched with FHF patients treated during the pre-pandemic period (1 March 2018 to 30 April 2019). We collected the rate of in-hospital postoperative complications and the postoperative functional outcomes at discharge and 3 months as measured by the Barthel Index (BI) and EuroQol visual analog scale (EQ-VAS). Functional outcome measures were compared between the pre-pandemic and pandemic periods. RESULTS: There were 197 and 287 patients in the pre-pandemic and pandemic groups, respectively. At the 3-month postoperative follow-up, the mean postoperative BI score and change in BI score were both significantly lower in the pandemic group indicating poorer postoperative function. Moreover, FHF patients treated during the pandemic had significantly more in-hospital complications (36.6% vs. 22.8%, p = 0.002). There was no significant difference in the 3-month EQ-VAS or change in the EQ-VAS between groups. CONCLUSION: The results of this study revealed a higher in-hospital complication rate and lower postoperative function at 3 months among FHF patients treated during the COVID-19 pandemic compared to the pre-pandemic period. Therefore, modified in-hospital and post-discharge protocols should be developed for implementation during pandemic crisis periods.

The Impact of COVID-19 on SARSCoV-2-Negative Elderly Patients with Hip Fractures: A Single-Center Retrospective Study from Shanghai, China.

Purpose: Coronavirus disease 2019 (COVID-19) has brought an unprecedented change in wellbeing globally. The spread of the pandemic reportedly reduced the incidence of activity-related trauma, while that of fragility fractures remained stable. Here, we aimed to identify the risk factors associated with the prognosis of SARS-CoV-2 negative elderly patients with hip fractures. Patients and Methods: This retrospective study included elderly patients with hip fractures between 1st January and 9th May during the COVID-19 pandemic (Experiment group) and the same period from 2017 to 2019 (Control group). Perioperative mortality, complications, and functional recovery were compared between two groups of different time frame in the total cohort and patients who received surgical treatment. Multiple linear regression was carried out to identify the risk factors influencing the prognosis of COVID-negative elderly patients with hip fractures. Results: The proportion of patients with admission time less than 24 hours and the 6-month postoperative Parker score were significantly decreased during COVID-19 compared with the pre-COVID-19 period (p < 0.001). Multiple linear regression demonstrated that TTA (defined as time from injury to admission), rehabilitation after discharge and outpatient follow-up were associated with the 6-month Parker score in the total population (p < 0.001) and in patients who received surgical treatment (p < 0.001). Conclusion: Elderly patients with hip fractures had a poorer prognosis in epidemic period despite being COVID-19 negative. Factors including timely admission, postoperative follow-up, and rehabilitation could optimize safety and significantly improve the prognosis of elderly COVID-19 negative patients with hip fractures, even during a pandemic.

Developing a minimum common dataset for hip fracture audit to help countries set up national audits that can support international comparisons.

AIMS: The aim of this study was to explore current use of the Global Fragility Fracture Network (FFN) Minimum Common Dataset (MCD) within established national hip fracture registries, and to propose a revised MCD to enable international benchmarking for hip fracture care. METHODS: We compared all ten established national hip fracture registries: England, Wales, and Northern Ireland; Scotland; Australia and New Zealand; Republic of Ireland; Germany; the Netherlands; Sweden; Norway; Denmark; and Spain. We tabulated all questions included in each registry, and cross-referenced them against the 32 questions of the MCD dataset. Having identified those questions consistently used in the majority of national audits, and which additional fields were used less commonly, we then used consensus methods to establish a revised MCD. RESULTS: A total of 215 unique questions were used across the ten registries. Only 72 (34%) were used in more than one national audit, and only 32 (15%) by more than half of audits. Only one registry used all 32 questions from the 2014 MCD, and five questions were only collected by a single registry. Only 21 of the 32 questions in the MCD were used in the majority of national audits. Only three fields (anaesthetic grade, operation, and date/time of surgery) were used by all ten established audits. We presented these findings at the Asia-Pacific FFN meeting, and used an online questionnaire to capture feedback from expert clinicians from different countries. A draft revision of the MCD was then presented to all 95 nations represented at the Global FFN conference in September 2021, with online feedback again used to finalize the revised MCD. CONCLUSION: The revised MCD will help aspirant nations establish new registry programmes, facilitate the integration of novel analytic techniques and greater multinational collaboration, and serve as an internationally-accepted standard for monitoring and improving hip fracture services.

Variations of the quality of care during the COVID-19 pandemic affected the mortality rate of non-COVID-19 patients with hip fracture.

INTRODUCTION: As COVID-19 roared through the world, governments worldwide enforced containment measures that affected various treatment pathways, including those for hip fractures (HFs). This study aimed to measure process and outcome indicators related to the quality of care provided to non-COVID-19 elderly patients affected by HF in Emilia-Romagna, a region of Italy severely hit by the pandemic. METHODS: We collected the hospital discharge records of all patients admitted to the hospitals of Emilia-Romagna with a diagnosis of HF from January to May in the years 2019 (pre-pandemic period) and 2020 (pandemic period). We analyzed surgery rate, surgery delays, length of hospital stay, timely rehabilitation, and 30-day mortality for each HF patient. We evaluated monthly data (2020 vs. 2019) with the chi-square and t-test, where appropriate. Logistic regression was used to investigate the differences in 30-day mortality. RESULTS: Our study included 5379 patients with HF. In April and May 2020, there was a significant increase in the proportion of HF patients that did not undergo timely surgery. In March 2020, we found a significant increase in mortality (OR = 2.22). Male sex (OR = 1.92), age ≥90 years (OR = 4.33), surgery after 48 hours (OR = 3.08) and not receiving surgery (OR = 6.19) were significantly associated with increased mortality. After adjusting for the aforementioned factors, patients hospitalized in March 2020 still suffered higher mortality (OR = 2.21). CONCLUSIONS: There was a reduction in the overall quality of care provided to non-COVID-19 elderly patients affected by HF, whose mortality increased in March 2020. Patients' characteristics and variations in processes of care partially explained this increase. Policymakers and professionals involved in the management of COVID-19 patients should be aware of the needs of patients with other health needs, which should be carefully investigated and included in future emergency preparedness and response plans.

Is It Possible to Predict the Length of Stay of Patients Undergoing Hip-Replacement Surgery?

The proximal fracture of the femur and hip is the most common reason for hospitalization in orthopedic departments. In Italy, 115,989 hip-replacement surgeries were performed in 2019, showing the economic relevance of studying this type of procedure. This study analyzed the data relating to patients who underwent hip-replacement surgery in the years 2010-2020 at the "San Giovanni di Dio e Ruggi d'Aragona" University Hospital of Salerno. The multiple linear regression (MLR) model and regression and classification algorithms were implemented in order to predict the total length of stay (LOS). Lastly, using a statistical analysis, the impact of COVID-19 was evaluated. The results obtained from the regression analysis showed that the best model was MLR, with an R2 value of 0.616, compared with XGBoost, Gradient-Boosted Tree, and Random Forest, with R2 values of 0.552, 0.543, and 0.448, respectively. The t-test showed that the variables that most influenced the LOS, with the exception of pre-operative LOS, were gender, age, anemia, fracture/dislocation, and urinary disorders. Among the classification algorithms, the best result was obtained with Random Forest, with a sensitivity of the longest LOS of over 89%. In terms of the overall accuracy, Random Forest and Gradient-Boosted Tree achieved a value of 71.76% and an error of 28.24%, followed by Decision Tree, with an accuracy of 71.13% and an error of 28.87%, and, finally, Support Vector Machine, with an accuracy of 65.06% and an error of 34.94%. A significant difference in cardiovascular disease, fracture/dislocation, and post-operative LOS variables was shown by the chi-squared test and Mann-Whitney test in the comparison between 2019 (before COVID-19) and 2020 (in full pandemic emergency conditions).

Early Postoperative Complications and Ambulation in Patients Treated for Hip Fractures, the Unexpected Positive Influence of the COVID-19 Pandemic: A Comparison Study.

BACKGROUND: The influence of the coronavirus disease 2019 (COVID-19) pandemic caused countries worldwide to implement lockdowns. Elective surgeries were temporarily suspended, with surgeries being performed only for emergent/urgent medical conditions such as hip fractures where early surgical intervention has shown decreased rates of morbidity/mortality. OBJECTIVES: To assess the indirect influence of the COVID-19 pandemic and associated lockdown on hip fracture patients, considering factors such as time to surgery, early postoperative complications, and ambulation status. METHODS: A comparative retrospective study was conducted on consecutive patients presenting to our emergency department (ED) with hip fractures that were treated surgically (N=29) during a 1-month period during the government lockdown due to the COVID-19 pandemic. The treatments were compared to consecutive patients who presented with hip fractures and were treated surgically (N=44) during the same timeframe in the previous year (control). Comparisons were made using t-test, ANOVA test, Fisher's exact test, and chi-square test. RESULTS: The COVID-19 group was operated on sooner (20.34 vs. 34.87 hours), had fewer early postoperative complications (10.3% vs. 31.8%), had better ambulatory status at discharge, and experienced a shorter hospital stay (5.93 vs. 8.13 days) with more patients being discharged home (72.4% vs. 22.7%). CONCLUSIONS: Patients presenting with hip fractures to our ED during the COVID-19 pandemic lockdown indirectly benefited from this situation by undergoing earlier surgical treatment, thus experiencing fewer early postoperative complications, faster ambulation, and sooner discharge.
