Yao W, Sun X, Tang W, Wang W, Lv Q, Ding W. Risk factors for hospital-acquired pneumonia in hip fracture patients: A systematic review and meta-analysis. Medicine (Baltimore) 2024; 103:e35773. [PMID: 38457536 PMCID: PMC10919500 DOI: 10.1097/md.0000000000035773] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/19/2023] [Revised: 09/04/2023] [Accepted: 10/03/2023] [Indexed: 03/10/2024] Open
Abstract
BACKGROUND This study aimed to comprehensively assess the prevalence and risk factors for Hospital-acquired pneumonia (HAP) in hip fracture patients by meta-analysis. METHODS Systematically searched 4 English databases and 4 Chinese databases from inception until October 20, 2022. All studies involving risk factors of HAP in patients with hip fractures will be considered. Newcastle-Ottawa Scale was used to evaluate the quality of the included studies. The results were presented through Review Manager 5.4 with the pooled odds ratio (OR) and 95% confidence interval. RESULTS Of 35 articles included in this study, the incidence of HAP was 8.9%. 43 risk factors for HAP were initially included, 23 were eventually involved in the meta-analysis, and 21 risk factors were significant. Among them, the 4 most frequently mentioned risk factors were as follows: Advanced age (OR 1.07, 95% CI 1.05-1.10), chronic obstructive pulmonary disease (COPD) (OR 3.44, 95% CI 2.83-4.19), time from injury to operation (OR 1.09, 95% CI 1.07-1.12), time from injury to operation ≥ 48 hours (OR 3.59, 95% CI 2.88-4.48), and hypoalbuminemia < 3.5g/dL (OR 2.68, 95% CI 2.15-3.36). DISCUSSION Hip fracture patients diagnosed with COPD have a 3.44 times higher risk of HAP compared to the general hip fracture patients. The risk of HAP also increases with age, with patients over 70 having a 2.34-fold higher risk and those over 80 having a 2.98-fold higher risk. These findings highlight the need for tailored preventive measures and timely interventions in vulnerable patient populations. Additionally, hip fracture patients who wait more than 48 hours for surgery have a 3.59-fold higher incidence of HAP. This emphasizes the importance of swift surgical intervention to minimize HAP risk. However, there are limitations to consider in this study, such as heterogeneity in selected studies, inclusion of only factors identified through multivariate logistic regression, and the focus on non-randomized controlled trial studies.

[PMID: 37989653 DOI: 10.1016/j.surge.2023.11.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2023] [Revised: 10/13/2023] [Accepted: 11/07/2023] [Indexed: 11/23/2023]
Abstract
BACKGROUND In studies on infection after hip fracture surgery, a common and serious complication, it remains unknown which comorbidity index is best for case-mix confounder adjustment. We evaluated the predictive ability of Charlson Comorbidity Index (CCI), Elixhauser Comorbidity Index (ECI), Rx-Risk Index (Rx-Risk), and Nordic Multimorbidity Index (NMI) for any infection up to 1 year from discharge after hip fracture surgery. METHODS Using Danish medical registries, we included 92,600 patients (mean age 83 years) surgically treated for hip fracture between 2004 and 2018. Comorbidity-index scores were calculated using prevalence of diagnosis codes, prescription codes, or both. Lookback periods of 1, 5, and 10 years were applied. Logistic regression was used to calculate c-index to assess discrimination of comorbidity indices individually and in combination with a base model of age and sex. Outcome was any infection (not only surgical site infection) in-hospital and 1 year after discharge. RESULTS At 10-year lookback period, the c-index for individual comorbidity indices for in-hospital infections varied from 0.53 to 0.56, similar to base model alone (0.56). The predictive ability of comorbidity indices in combination with base model varied from 0.56 to 0.57. Within 1 year after discharge, NMI in combination with base model had best predictive ability for infection (c-index = 0.62), followed by CCI and ECI (c-index = 0.60) and Rx-Risk (c-index = 0.58). Discrimination was similar for all lookback periods. CONCLUSIONS Comorbidity indices have low predictive ability for any infection up to 1 year after hip fracture surgery, similar to that of age and sex alone. For case-mix adjustment, evaluated comorbidity indices are of equal value.

Abstract
OBJECTIVE This study aimed to systematically assess the incidence and risk factors for hospital-acquired pneumonia (HAP) in hip fracture patients by meta-analysis. METHODS Systematically searched four English databases (PubMed, EMBASE, The Cochrane Library, and Web Of Science) and four Chinese databases (CNKI, CQVIP, Sinomed, and WAN FANG) from inception until 20 November 2023. All studies involving risk factors of HAP in patients with hip fractures were considered. Newcastle-Ottawa Scale was used to evaluate the quality of the included studies. The results were presented with the pooled odds ratio (OR) and 95% confidence interval (95% CI). RESULTS Of 35 articles (337,818 patients) included in this study, the incidence of HAP was 89 per 1000 cases. Twenty-three risk factors were eventually involved in the meta-analysis, and 21 risk factors were significant. Our study has identified four significant risk factors (advanced age, preoperative time, COPD, and hypoalbuminemia) associated with HAP, as follows: Advanced age as a continuous variable (OR 1.07, 95% CI 1.05-1.10), Advanced age > 70 years (OR 2.34, 95% CI 1.77-3.09), Advanced age > 80 years (OR 2.98, 95% CI 2.06-4.31), Chronic obstructive pulmonary disease (COPD) (OR 3.44, 95% CI 2.83-4.19), Time from injury to operation as a continuous variable (OR 1.09, 95% CI 1.07-1.12), Time from injury to operation ≥48 h (OR 3.59, 95% CI 2.88-4.48), Hypoalbuminemia < 3.0 g/dL (OR 3.03, 95% CI 1.93-4.73), and Hypoalbuminemia < 3.5 g/dL (OR 2.68, 95% CI 2.15-3.36). However, it is important to note that all the studies included in our research were retrospective in nature, which introduces certain limitations to the level of evidence and the ability to establish causal inferences. DISCUSSION Patients who have suffered hip fractures are at an increased risk of developing postoperative hospital-acquired pneumonia, which can lead to prolonged hospital stays and adverse clinical outcomes. Consequently, the identification of these risk factors offers novel insights and methodologies for healthcare professionals in terms of both prevention and treatment.

Home Versus Hospital Rehabilitation of Older Adults Following Hip Fracture Yields Similar Patient-Reported Outcome Measures. INQUIRY : A JOURNAL OF MEDICAL CARE ORGANIZATION, PROVISION AND FINANCING 2024; 61:469580241230293. [PMID: 38491840 PMCID: PMC10943717 DOI: 10.1177/00469580241230293] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/18/2023] [Revised: 01/02/2024] [Accepted: 01/08/2024] [Indexed: 03/18/2024]
Abstract
The increase in hip fractures (HF) due to aging of the population and the rise in attractiveness of services provided at home following the COVID-19 pandemic, emphasize the need to compare outcomes of home versus hospital HF rehabilitation. To date, studies comparing the 2 services have focused primarily on clinical outcomes rather than patient-reported outcomes (PROs). This longitudinal observational study evaluated PROs of older adults with HF in the 2 settings. The SF36 questionnaire was used to measure PROs 3 times after surgery. The first PRO was retrospective and reflected pre-fracture health status. Descriptive statistics and mixed-effect logistic regression were used. Of 86 patients participating in the study, 41 had home rehabilitation and 45 had hospital rehabilitation. In both groups, the mental and physical scores plummeted 2 weeks after the HF, compared to pre-fracture status. The difference in improvement from pre-fracture status to recovery in both groups, were not significantly (P < .05) different, except for the pain domain. PROs of home versus hospital rehabilitation were similar, suggesting that rehabilitation at home can be as effective as hospital rehabilitation for suitable patients. This knowledge can improve quality of care in an aging global population.

Osteoporos Int 2023; 34:1739-1749. [PMID: 37330437 PMCID: PMC10511604 DOI: 10.1007/s00198-023-06823-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/20/2023] [Accepted: 06/06/2023] [Indexed: 06/19/2023]
Abstract
Impact of comorbidity on infection risk among hip fracture patients is unclear. We found high incidence of infection. Comorbidity was an important risk factor for infection up to 1 year after surgery. Results indicates a need for additional investment in pre- and postoperative programs that assist patients with high comorbidity. PURPOSE Comorbidity level and incidence of infection have increased among older patients with hip fracture. The impact of comorbidity on infection risk is unclear. We conducted a cohort study examining the absolute and relative risks of infection in relation to comorbidity level among hip fracture patients. METHODS Utilizing Danish population-based medical registries, we identified 92,600 patients aged ≥ 65 years undergoing hip fracture surgery between 2004 and 2018. Comorbidity was categorized by Charlson comorbidity index scores (CCI): none (CCI = 0), moderate (CCI = 1-2), or severe (CCI ≥ 3). Primary outcome was any hospital-treated infection. Secondary outcomes were hospital-treated pneumonia, urinary tract infection, sepsis, reoperation due to surgical-site infection (SSI), and a composite of any hospital- or community-treated infection. We calculated cumulative incidence and hazard ratios (aHRs) adjusted for age, sex, and surgery year, including 95% confidence intervals (CIs). RESULTS Prevalence of moderate and severe comorbidity was 40% and 19%, respectively. Incidence of any hospital-treated infection increased with comorbidity level within 0-30 days (none 13% vs. severe 20%) and 0-365 days (none 22% vs. 37% severe). Patients with moderate and severe comorbidity, compared to no comorbidity, had aHRs of 1.3 (CI: 1.3-1.4) and 1.6 (CI: 1.5-1.7) within 0-30 days, and 1.4 (CI: 1.4-1.5) and 1.9 (CI: 1.9-2.0) within 0-365, respectively. Highest incidence was observed for any hospital- or community-treated infection (severe 72%) within 0-365 days. Highest aHR was observed for sepsis within 0-365 days (severe vs. none: 2.7 (CI: 2.4-2.9)). CONCLUSION Comorbidity is an important risk factor for infection up to 1 year after hip fracture surgery.

A systematic review and meta-analysis of risk factors associated with healthcare-associated infections among hospitalised patients in Chinese general hospitals from 2001 to 2022. J Hosp Infect 2023; 135:37-49. [PMID: 36907333 DOI: 10.1016/j.jhin.2023.02.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2022] [Revised: 02/16/2023] [Accepted: 02/26/2023] [Indexed: 03/13/2023]
Abstract
BACKGROUND Healthcare-associated infections (HAIs) are a serious global public health issue. However, a comprehensive analysis of risk factors for HAIs has yet been undertaken at a large scale among general hospitals in China. The aim of this review is to assess risk factors associated with HAIs in Chinese general hospitals. METHODS Medline, EMBASE and Chinese Journals Online databases were searched to find studies published from January 1st 2001 to May 31st 2022. The random-effects model was used to estimate odds ratio (OR). Heterogeneity was assessed based on the τˆ2 and I2 statistics. RESULTS 5,037 published papers were identified from the initial search and 58 studies were included in the quantitative meta-analysis. 1,211,117 hospitalised patients were incorporated covering 41 regions in 23 provinces of China and 29,737 were identified as having HAIs. Our review showed that HAIs were significantly associated with sociodemographic characteristics including age older than 60 years (OR: 1.74[1.38-2.19]) and male sex (1.33[1.20-1.47]); invasive procedures (3.54[1.50-8.34]); health conditions such as chronic diseases (1.49[1.22-1.82]), coma (OR: 5.12[1.70-15.38]) and immunosuppression (2.45[1.55-3.87]). Other risk factors included long-term bed (5.84[5.12-6.66]), and healthcare-related risk factors as chemotherapy (1.96[1.28-3.01]), haemodialysis (3.12[1.80-5.39]), hormone therapy (2.96[1.96-4.45]), immunosuppression (2.45[1.55-3.87]) and use of antibiotics (6.64 [3.16-13.96]), and longer than 15 hospitalisation days (13.36[6.80-26.26]). CONCLUSIONS Being male and aged over 60 years, invasive procedure, health conditions, healthcare-related risk factors, and longer than 15 hospitalisation days were the main risk factors associated with HAIs in Chinese general hospitals. This supports the evidence base to inform the relevant cost effective prevention and control strategies.
