Four-wheeled walker related injuries in older adults in the Netherlands.

BACKGROUND: With ageing populations worldwide, mobility devices are used more than ever. In the current literature there is no consensus whether the available mobility devices safely improve the mobility of their users. Also, evidence is lacking concerning the risks and types of injuries sustained while using a four-wheeled walker. OBJECTIVE: To assess injury risks and injury patterns in older adults (≥65 years) who presented at Emergency Departments (ED) in the Netherlands with an injury due to using a four-wheeled walker. DESIGN AND SETTING: In this study, the Dutch Injury Surveillance System was used to obtain a national representative sample of annual ED visits in the Netherlands in the adult population (≥65 years) sustaining an injury while using a four-wheeled walker. The numbers of four-wheeled walker users in the Netherlands were obtained from the national insurance board. The numbers of ED visits were divided by the numbers of four-wheeled walker users to calculate age- and sex-specific injury risks. RESULTS: Annually 1869 older adults visited an ED after sustaining an injury while using a four-wheeled walker. Falls were the main cause of injury (96%). The injury risk was 3.1 per 100 users of four-wheeled walkers. Women (3.5 per 100 users) had a higher risk than men (2.0 per 100 users). Injury risk was the highest in women aged 85 years and older (6.2 per 100 users). The majority of injuries were fractures (60%) with hip fracture (25%) being the most common injury. Nearly half of all four-wheeled walker related injuries required hospitalisation, mostly due to hip fractures. Healthcare costs per injury were approximately €12 000. CONCLUSIONS: This study presents evidence that older adults experiencing a fall while using a four-wheeled walker are at high risk to suffer severe injuries.

Postoperative cognitive dysfunction in geriatric patients.

Postoperative cognitive dysfunction (POCD) is a severe long-term complication after surgical procedures. POCD is mainly seen among geriatric patients. Hospitalization, extent of surgery, and systemic inflammatory response might contribute to POCD. The possible influence of the type of anesthesia is discussed. POCD is often not recognized; thus, incidence rates are likely to be underestimated (19-40%). POCD is associated with major consequences for the individual patient, e.g., delayed long-term recovery, reduced quality of life, and an increased mortality rate. Multiple risk factors have been identified over the last decade. However, the exact etiology is still unknown. This mini-review summarizes the recent developments concerning POCD prevention, diagnosis, and treatment.

Perioperative care of the older patient.

Nearly 60% of the Dutch population undergoing surgery is aged 65 years and over. Older patients are at increased risk of developing perioperative complications (e.g., myocardial infarction, pneumonia, or delirium), which may lead to a prolonged hospital stay or death. Preoperative risk stratification calculates a patient's risk by evaluating the presence and extent of frailty, pathophysiological risk factors, type of surgery, and the results of (additional) testing. Type of anesthesia, fluid management, and pain management affect outcome of surgery. Recent developments focus on multimodal perioperative care of the older patient, using minimally invasive surgery, postoperative anesthesiology rounds, and early geriatric consultation.

The available evidence on demineralised bone matrix in trauma and orthopaedic surgery: A systematic review.

OBJECTIVES: The aim of this systematic literature review was to assess the clinical level of evidence of commercially available demineralised bone matrix (DBM) products for their use in trauma and orthopaedic related surgery. METHODS: A total of 17 DBM products were used as search terms in two available databases: Embase and PubMed according to the Preferred Reporting Items for Systematic Reviews and Meta Analyses statement. All articles that reported the clinical use of a DBM-product in trauma and orthopaedic related surgery were included. RESULTS: The literature search resulted in 823 manuscripts of which 64 manuscripts met the final inclusion criteria. The included manuscripts consisted of four randomised controlled trials (level I), eight cohort studies (level III) and 49 case-series (level IV). No clinical studies were found for ten DBM products, and most DBM products were only used in combination with other grafting materials. DBM products were most extensively investigated in spinal surgery, showing limited level I evidence that supports the use Grafton DBM (Osteotech, Eatontown, New Jersey) as a bone graft extender in posterolateral lumbar fusion surgery. DBM products are not thoroughly investigated in trauma surgery, showing mainly level IV evidence that supports the use of Allomatrix (Wright Medical, London, United Kingdom), DBX (DePuy Synthes, Zuchwil, Switzerland), Grafton DBM, or OrthoBlast (Citagenix Laval, Canada) as bone graft extenders. CONCLUSIONS: The clinical level of evidence that supports the use of DBM in trauma and orthopaedic surgery is limited and consists mainly of poor quality and retrospective case-series. More prospective, randomised controlled trials are needed to understand the clinical effect and impact of DBM in trauma and orthopaedic surgery.Cite this article: J. van der Stok, K. A. Hartholt, D.

Epidemiology and health-care utilisation of wrist fractures in older adults in The Netherlands, 1997-2009.

INTRODUCTION: Wrist fractures are common in older adults and are expected to increase because of ageing populations worldwide. The introduction of plate and screw fixation has changed the management of this trauma in many patients. For policymaking it is essential to gain insight into trends in epidemiology and healthcare utilisation. The purpose of this study was to determine trends in incidence, hospitalisation and operative treatment of wrist fractures. METHODS: A population-based study of patients aged 50 years and older using the Dutch National Injury Surveillance System and the National Hospital Discharge Registry. Data on emergency department visits, hospitalisations and operative treatment for wrist fractures within the period 1997-2009 were analysed. RESULTS: In women, the age-standardised incidence rate of wrist fractures decreased from 497.2 per 100,000 persons (95% confidence interval, 472.3-522.1) in 1997 to 445.1 (422.8-467.4) in 2009 (P for trend < 0.001). In men, no significant trends were observed in the same time period. Hospitalisation rates increased from 30.1 (28.3-31.9) in 1997 to 78.9 (75.1-82.8) in 2009 in women (P < 0.001), and from 6.4 (6.0-6.8) to 18.4 (17.3-19.5) in men (P < 0.001). There was a strong increase in operative treatment of distal radius fractures, especially due to plate fixation techniques in all age groups. CONCLUSION: Incidence rates of wrist fractures decreased in women and remained stable in men, but hospitalisation rates strongly increased due to a steep rise in operative treatments. The use of plate and screw fixation techniques for distal radius fractures increased in all age groups.

Better drug knowledge with fewer drugs, both in the young and the old.

Little is known about drug knowledge of patients, which is relevant for both the compliance and quality of pharmacotherapy. Drug knowledge was quantified in 160 patients in the outpatient clinics of the departments of Internal and Geriatric Medicine. Medication knowledge was generally poor, especially among older patients. Better knowledge was associated with the use of fewer drugs. Caregivers of dementia patients performed as well as younger patients, indicating that older people can perform well, if well-instructed.
