Process evaluation of a complex workplace intervention to prevent musculoskeletal pain in nursing staff: results from INTEVAL_Spain

2021

Abstract Background INTEVAL_Spain was a complex workplace intervention to prevent and manage musculoskeletal pain among nursing staff. Process evaluations can be especially useful for complex and multifaceted interventions through identifying the success or failure factors of an intervention to improve the intervention implementation. Objectives This study performed a process evaluation of INTEVAL_Spain and aimed to examine whether the intervention was conducted according to the protocol, to investigate the fulfilment of expectations and the satisfaction of workers. Methods The intervention was a two-armed cluster randomized controlled trial and lasted 1 year. The process evaluation include…

Do adolescents with long-term illnesses and disabilities have increased risks of sports related injuries?

2017

peer-reviewed Background: The aim of this study is to examine the rates of sports related injuries in adolescents based on the severity of their long-term illnesses or disabilities (LTID). Few injury prevention strategies in sports and health promotion have explored disaggregation by disability. Methods: Data obtained from the 2014 Finnish Health Behaviour in School-aged Children survey (n = 3716, mean age = 14.8, SD = 1.03) were grouped into adolescents with and without LTID. A further indicator or severity was determined when adolescents reported their LTID affected their participation (affected LTID). Odds ratio (95% CI) were used to determine the associations between sports related inju…

Procedural Memory Following Moderate-Severe Traumatic Brain Injury: Group Performance and Individual Differences on the Rotary Pursuit Task

2019

The impact of traumatic brain injury (TBI) on procedural memory has received significantly less attention than declarative memory. Although to date studies on procedural memory have yielded mixed findings, many rehabilitation protocols (e.g., errorless learning) rely on the procedural memory system, and assume that it is relatively intact. The aim of the current study was to determine whether individuals with TBI are impaired on a task of procedural memory as a group, and to examine the presence of individual differences in performance. We administered to a sample of 36 individuals with moderate-severe TBI and 40 healthy comparisons (HCs) the rotary pursuit task, and then examined their rat…

A Review of Occlusion as a Tool to Assess Attentional Demand in Driving

2021

Objective The aim of this review is to identify how visual occlusion contributes to our understanding of attentional demand and spare visual capacity in driving and the strengths and limitations of the method. Background The occlusion technique was developed by John W. Senders to evaluate the attentional demand of driving. Despite its utility, it has been used infrequently in driver attention/inattention research. Method Visual occlusion studies in driving published between 1967 and 2020 were reviewed. The focus was on original studies in which the forward visual field was intermittently occluded while the participant was driving. Results Occlusion studies have shown that attentional demand…

Accumulation of sensory difficulties predicts fear of falling in older women

2013

Objectives: To explore whether the accumulation of sensory difficulties predicts fear of falling (FOF), and whether the traits correlate with each other regardless of familial factors. Methods: Self-reported hearing, vision and balance difficulties, and FOF were assessed using structured questionnaires at the baseline and after a 3-year follow-up in 63- to 76-year-old women ( n = 434). Results: Among the women without FOF at baseline ( n = 245), 41% reported FOF at follow-up. Increasing numbers of sensory difficulties at baseline predicted higher incidence of FOF. The relationship between accumulated sensory difficulties and FOF was not mediated by familial factors. Discussion: The accumul…

Towards real-time detection of cognitive effort in driving: Contribution of cardiac measurement

2016

En 2013, on estime que 40 à 50% des accidents corporels seraient dus à des défauts d'attention de la part du conducteur. Des études récentes ont mis en évidence la possibilité de détecter des états attentionnels dégradés afin de pouvoir mieux assister le conducteur ; ce thème de recherche représente donc un nouveau gisement de sécurité routière. Cette étude se concentre sur la détection de l'effort cognitif fournit par les conducteurs et cherche, par l'étude de la variation du rythme cardiaque, à identifier un indicateur d'effort sensible sur de courtes fenêtres temporelles.Chacun des 18 participants a passé 8 conditions expérimentales sur simulateur de conduite : la moitié où seule une tâc…

Video-assisted surgery: suggestions for failure prevention in laparoscopic cholecystectomy

2014

Background: Surgery differs from other medical specialties in its execution. It is often complex and includes considerable individual variations. Observing problems in operating theatres (OT) allows for the identification of system failures which should be defined for learning purposes to increase patient safety and enhance general safety culture within hospital organizations. This study evaluates a common video-assisted surgical procedure, laparoscopic cholecystectomy (LC) through failure analysis. The profile of the LC procedure and failure sources is presented. Methods: Data consisted video-observations and interviews concerning twelve LC operations performed at a day surgery unit. All o…

Evaluation of the effectiveness of occupational injury prevention programs at the company level

2013

The objective was to evaluate the effectiveness of an occupational injury prevention program, known as the Preferential Action Plan (PAP), focused on companies with high incidence rates of occupational injuries. We studied 1189 companies in the industrial, construction and services sectors between 1999 and 2007 in the Valencia region (Spain). Our sample included 507,262 workers, among whom 44,250 non-fatal occupational injuries with at least a workday lost were registered. Companies included in a PAP program were divided into three intervention groups, according to the year that each company entered into a PAP (2000, 2001, and 2002). We calculated annual percentage change in incidence rates…

WHIPLASH INJURIES IN SPORTS ACTIVITIES. CLINICAL OUTCOME AND BIOMECHANICS

2013

Background Cervical whiplash syndrome, or hyperextension-hyperflexion injury, is a common traumatic injury in sports activities. The mechanisms of injury that cause cervical whiplash syndrome vary, but they may be sufficient enough to cause chronic whiplash syndrome. Methods and Patients Over 150 injuries were recorded in sports in our Orthopaedic Departments between the years of 2008 and 2011. Whiplash spine injuries have been reported in most contact sports, including indoor soccer, basketball, and wrestling, and in several non contact sports, such as diving. Whiplash spine injuries are estimated to occur in high percentage of indoor soccer players, and most commonly on defensive players.…
