Abstract
INTRODUCTION The long-term risk of cardiovascular events caused by chronic kidney disease (CKD) is well described in the general population. Less is known concerning the risk of postoperative cardiovascular events in geriatric hip fracture patients with CKD. METHODS This study involved patients at least 65 years of age who received surgery for acute hip fracture between January 2000 and April 2016. We identified CKD patients with a baseline diagnosis of CKD or an estimated glomerular filtration rate (eGFR) < 60 mL/min/1.73 m2 at admission. Each CKD patient was matched, for age, gender, fracture type, and year of admission, with 4 control non-CKD patients. The primary endpoint was a compositepostoperative cardiovascular events, including pulmonary embolism, angina pectoris, myocardial infarction, heart failure, arrhythmia, stroke, and death. Conditional logistic regression was used to evaluate the association between CKD and the outcome after adjusting for potential confounders including age, gender, fracture type, body mass index, preexisting comorbidities, history of cardiovascular events, and the Charlson Comorbidity Index (CCI). RESULTS Three hundred and seventy-five CKD patients were matched with 1,438 non-CKD patients. The mean age of the CKD patients was 81.9 ± 7.0 (mean ± SD), 69.9% were females, and 59.2% had an intertrochanteric fracture. Compared to non-CKD patients, CKD patients had a higher proportion of preexisting comorbidities, including hypertension, coronary heart disease, heart failure, and type 2 diabetes (all p < 0.05). The risk of postoperative cardiovascular events was 125.3 per 1000 persons (95%CI, 91.8-158.8) in CKD patients and 64.7 per 1000 persons (95%CI, 52.0-77.4) in non-CKD patients. A 1.96-fold risk of cardiovascular events after hip fracture surgery was found in CKD patients than those without CKD (adjusted OR, 1.96; 95%CI, 1.23-3.12). CONCLUSION Patients with CKD were more likely to have cardiovascular events after hip fracture surgery than those without CKD. Appropriate preoperative cardiovascular risk assessment and corresponding preventive and therapeutic measures should be given to this vulnerable population to mitigate such complications.

Lean Six Sigma Approach for Reducing Length of Hospital Stay for Patients with Femur Fracture in a University Hospital. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18062843. [PMID: 33799518 PMCID: PMC8000325 DOI: 10.3390/ijerph18062843] [Citation(s) in RCA: 26] [Impact Index Per Article: 8.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/20/2021] [Revised: 03/04/2021] [Accepted: 03/05/2021] [Indexed: 11/30/2022]
Abstract
Surgical intervention within 48 h of hospital admission is the gold standard procedure for the management of elderly patients with femur fractures, since the increase in preoperative waiting time is correlated with the onset of complications and longer overall length of stay (LOS) in the hospital. However, national evidence demonstrates that there is still the need to provide timely intervention for this type of patient, especially in some regions of central southern Italy. Here we discuss the introduction of a diagnostic–therapeutic assistance pathway (DTAP) to reduce the preoperative LOS for patients undergoing femur fracture surgery in a university hospital. A Lean Six Sigma methodology, based on the DMAIC cycle (Define, Measure, Analyze, Improve, Control), is implemented to evaluate the effectiveness of the DTAP. Data were retrospectively collected and analyzed from two groups of patients before and after the implementation of DTAP over a period of 10 years. The statistics of the process measured before the DTAP showed an average preoperative LOS of 5.6 days (standard deviation of 3.2), thus confirming the need for corrective actions to reduce the LOS in compliance with the national guidelines. The influence of demographic and anamnestic variables on the LOS was evaluated, and the impact of the DTAP was measured and discussed, demonstrating the effectiveness of the improvement actions implemented over the years and leading to a significant reduction in the preoperative LOS, which decreased to an average of 3.5 days (standard deviation of 3.60). The obtained reduction of 39% in the average LOS proved to be in good agreement with previously developed DTAPs for femur fracture available in the literature.
