          Abstract

          Background: Delirium is a common complication after surgery in the elderly that leads to increased length of stay and other adverse outcomes. The aim of this study was to better understand the exact causes of post-operative delirium in patients undergoing surgery for neck of femur (NOF) fractures.

          Methods: We performed a prospective cohort study of 381 consecutive patients undergoing surgery for NOF fractures at a single institution. Baseline cognitive status and risk factors were recorded on admission. Post-operative cognitive status was assessed at regular intervals until discharge. Binary logistic regression was performed to identify independent predictors of delirium.

          Results: Patients who developed post-operative delirium ( n = 70) were significantly older (average age 83 vs. 78, p = 0.019) and more likely to be female (79% vs. 67%, p = 0.062) than non-affected patients. The presence of delirium was associated with increased length of stay (13 vs. 10 days, p = 0.001) and 1-year mortality (25.7% vs. 15% p = 0.03). Independent predictors of delirium included age ≥65 years (Odds Ratio = 5.8), presence of anaemia (OR = 2.9), hypoxia (OR = 2.86), cardiac disease (OR = 2.8), Chronic Obstructive Pulmonary Disease (OR = 2.5), new onset electrolyte imbalance (OR = 2.2) and renal failure (OR = 1.9).

          Conclusion: Overall analysis demonstrated an increased incidence of delirium in older females with greater comorbid conditions. It was also found to be associated with increased morbidity and mortality. We recommend clinicians put greater effort into recognising risk factors of delirium and diagnosing it in a timely manner to mitigate its effects.

          Efficacy of a comprehensive geriatric intervention in older patients hospitalized for hip fracture: a randomized, controlled trial.

          To evaluate whether an early multidisciplinary geriatric intervention in elderly patients with hip fracture reduced length of stay, morbidity, and mortality and improved functional evolution. Randomized, controlled intervention trial. Orthopedic ward in a university hospital. Three hundred nineteen patients aged 65 and older hospitalized for hip fracture surgery. Participants were randomly assigned to a daily multidisciplinary geriatric intervention (n=155) or usual care (n=164) during hospitalization in the acute phase of hip fracture. Primary endpoints were in-hospital length of stay and incidence of death or major medical complications. Secondary endpoints were the rate of recovery of previous activities of daily living and ambulation ability at 3, 6, and 12 months. Median length of stay was 16 days in the geriatric intervention group and 18 days in the usual care group (P=.06). Patients assigned to the geriatric intervention showed a lower in-hospital mortality (0.6% vs 5.8%, P=.03) and major medical complications rate (45.2% vs 61.7%, P=.003). After adjustment for confounding variables, geriatric intervention was associated with a 45% lower probability of death or major complications (95% confidence interval=7-68%). More patients in the geriatric intervention group achieved a partial recovery at 3 months (57% vs 44%, P=.03), but there were no differences between the groups at 6 and 12 months. Early multidisciplinary daily geriatric care reduces in-hospital mortality and medical complications in elderly patients with hip fracture, but there is not a significant effect on length of hospital stay or long-term functional recovery.

            Complications of hip fractures: A review.

            Nowadays, fracture surgery represents a big part of the orthopedic surgeon workload, and usually has associated major clinical and social cost implications. These fractures have several complications. Some of these are medical, and other related to the surgical treatment itself. Medical complications may affect around 20% of patients with hip fracture. Cognitive and neurological alterations, cardiopulmonary affections (alone or combined), venous thromboembolism, gastrointestinal tract bleeding, urinary tract complications, perioperative anemia, electrolytic and metabolic disorders, and pressure scars are the most important medical complications after hip surgery in terms of frequency, increase of length of stay and perioperative mortality. Complications arising from hip fracture surgery are fairly common, and vary depending on whether the fracture is intracapsular or extracapsular. The main problems in intracapsular fractures are biological: vascularization of the femoral head, and lack of periosteum -a major contributor to fracture healing- in the femoral neck. In extracapsular fractures, by contrast, the problem is mechanical, and relates to load-bearing. Early surgical fixation, the role of anti-thromboembolic and anti-infective prophylaxis, good pain control at the perioperative, detection and management of delirium, correct urinary tract management, avoidance of malnutrition, vitamin D supplementation, osteoporosis treatment and advancement of early mobilization to improve functional recovery and falls prevention are basic recommendations for an optimal maintenance of hip fractured patients.

              The incidence of delirium associated with orthopedic surgery: a meta-analytic review.

              The aim of this study was to perform a systematic review and meta-analysis of the literature regarding the incidence of delirium following orthopedic surgery. Relevant papers were sourced from online databases and gray literature. Included studies used a validated diagnostic method to measure the incidence of delirium in a prospective sample of adult/elderly orthopedic patients. Data were subject to meta-analysis after stratification by type of surgery (elective v. emergency) and inclusion/exclusion of pre-existing cognitive impairment. A funnel plot assessed for publication bias. 26 publications reported an incidence of postoperative delirium of 4-53.3% in hip fracture samples and 3.6-28.3% in elective samples. Significant heterogeneity was evident, and this persisted despite stratification. Hip fracture was associated with a higher risk of delirium than elective surgery both when the cognitively impaired were included in the sample (random effects pooled estimate = 21.7% [95% CI = 14.6-28.8] vs. 12.1% [95% CI = 9.6-14.6]), and when the cognitively impaired were excluded (random effects pooled estimate = 25% [95% CI = 15.7-34.7] vs. 8.8% [95% CI = 4.1-13.6]). The funnel plot showed a deficit of small studies showing low risk and large studies showing high risk. In eight hip fracture studies, the proportion of delirium cases with a preoperative onset ranged from 34 to 92%. Delirium occurs more commonly with hip fracture than elective surgery, and frequently has a preoperative onset when associated with trauma. Recommendations are made with the aim of standardizing future research in order to further explore and reduce the heterogeneity and possible publication bias observed.
