Integrated approach to prevent functional decline in hospitalized elderly: the Prevention and Reactivation Care Program (PReCaP)

BackgroundHospital related functional decline in older patients is an underestimated problem. Thirty-five procent of 70-year old patients experience functional decline during hospital admission in comparison with pre-illness baseline. This percentage increases considerably with age.Methods/designTo address this issue, the Vlietland Ziekenhuis in The Netherlands has implemented an innovative program (PReCaP), aimed at reducing hospital related functional decline among elderly patients by offering interventions that are multidisciplinary, integrated and goal-oriented at the physical, social, and psychological domains of functional decline.DiscussionThis paper presents a detailed description of the intervention, which incorporates five distinctive elements: (1) Early identification of elderly patients with a high risk of functional decline, and if necessary followed by the start of the reactivation treatment within 48 h after hospital admission; (2) Intensive follow-up treatment for a selected patient group at the Prevention and Reactivation Centre (PRC); (3) Availability of multidisciplinary geriatric expertise; (4) Provision of support and consultation of relevant professionals to informal caregivers; (5) Intensive follow-up throughout the entire chain of care by a casemanager with geriatric expertise. Outcome and process evaluations are ongoing and results will be published in a series of future papers.Trial registrationThe Netherlands National Trial Register: NTR2317

The Prevention and Reactivation Care Program: intervention fidelity matters

BackgroundThe Prevention and Reactivation Care Program (PReCaP) entails an innovative multidisciplinary, integrated and goal oriented approach aimed at reducing hospital related functional decline among elderly patients. Despite calls for process evaluation as an essential component of clinical trials in the geriatric care field, studies assessing fidelity lag behind the number of effect studies. The threefold purpose of this study was (1) to systematically assess intervention fidelity of the hospital phase of the PReCaP in the first year of the intervention delivery; (2) to improve our understanding of the moderating factors and modifications affecting intervention fidelity; and (3) to explore the feasibility of the PReCaP fidelity assessment in view of the modifications.MethodsBased on the PReCaP description we developed a fidelity instrument incorporating nineteen (n=19) intervention components. A combination of data collection methods was utilized, i.e. data collection from patient records and individual Goal Attainment Scaling care plans, in-depth interviews with stakeholders, and non-participant observations. Descriptive analysis was performed to obtain levels of fidelity of each of the nineteen PReCaP components. Moderating factors were identified by using the Conceptual Framework for Implementation Fidelity.ResultsTen of the nineteen intervention components were always or often delivered to the group of twenty elderly patients. Moderating factors, such as facilitating strategies and context were useful in explaining the non- or low-adherence of particular intervention components.ConclusionsFidelity assessment was carried out to evaluate the adherence to the PReCaP in the Vlietland Ziekenhuis in the Netherlands. Given that the fidelity was assessed in the first year of PReCaP implementation it was commendable that ten of the nineteen intervention components were performed always or often. The adequate delivery of the intervention components strongly depended on various moderating factors. Since the intervention is still developing and undergoing continuous modifications, it has been concluded that the fidelity criteria should evolve with the modified intervention. Furthermore, repeated intervention fidelity assessments will be necessary to ensure a valid and reliable fidelity assessment of the PReCaP.Trial registrationThe Netherlands National Trial Register: NTR2317

Situational awareness, relational coordination and integrated care delivery to hospitalized elderly in the Netherlands: A comparison between hospitals

BackgroundIt is known that interprofessional collaboration is crucial for integrated care delivery, yet we are still unclear about the underlying mechanisms explaining effectiveness of integrated care delivery to older patients. In addition, we lack research comparing integrated care delivery between hospitals. Therefore, this study aims to (i) provide insight into the underlying components ‘relational coordination’ and ‘situational awareness’ of integrated care delivery and the role of team and organizational context in integrated care delivery; and (ii) compare situational awareness, relational coordination, and integrated care delivery of different hospitals in the Netherlands.MethodsThis cross-sectional study took place in 2012 among professionals from three different hospitals involved in the delivery of care to older patients. A total of 215 professionals filled in the questionnaire (42% response rate).Descriptive statistics and paired-sample t-tests were used to investigate the level of situational awareness, relational coordination, and integrated care delivery in the three different hospitals. Correlation and multilevel analyses were used to investigate the relationship between background characteristics, team context, organizational context, situational awareness, relational coordination and integrated care delivery.ResultsNo differences in background characteristics, team context, organizational context, situational awareness, relational coordination and integrated care delivery were found among the three hospitals. Correlational analysis revealed that situational awareness (r = 0.30; p < 0.01), relational coordination (r = 0.17; p < 0.05), team climate (r = 0.29; p < 0.01), formal internal communication (r = 0.46; p < 0.01), and informal internal communication (r = 0.36; p < 0.01) were positively associated with integrated care delivery. Stepwise multilevel analyses showed that formal internal communication (p < 0.001) and situational awareness (p < 0.01) were associated with integrated care delivery. Team climate was not significantly associated with integrated care delivery when situational awareness and relational coordination were included in the equation. Thus situational awareness acted as mediator between team climate and integrated care delivery among professionals delivering care to older hospitalized patients.ConclusionsThe results of this study show the importance of formal internal communication and situational awareness for quality of care delivery to hospitalized older patients.

Residential Traffic Exposure and Children's Emergency Department Presentation for Asthma: A Spatial Study

BackgroundThere is increasing evidence that residential proximity to roadways is associated with an elevated risk of asthma exacerbation. However, there is no consensus on the distance at which these health effects diminishes to background levels. Therefore the optimal, clinically relevant measure of exposure remains uncertain. Using four spatially defined exposure metrics, we evaluated the association between residential proximity to roadways and emergency department (ED) presentation for asthma in Perth, Western Australia.MethodThe study population consisted of 1809 children aged between 0 and 19 years who had presented at an ED between 2002 and 2006 and were resident in a south-west metropolitan area of Perth traversed by major motorways. We used a 1:2 matched case-control study with gastroenteritis and upper limb injury as the control conditions. To estimate exposure to traffic emissions, we used 4 contrasting methods and 2 independently derived sources of traffic data (video-monitored traffic counts and those obtained from the state government road authority). The following estimates of traffic exposure were compared: (1) a point pattern method, (2) a distance-weighted traffic exposure method, (3) a simple distance method and (4) a road length method.ResultsRisk estimates were sensitive to socio-economic gradients and the type of exposure method that was applied. Unexpectedly, a range of apparent protective effects were observed for some exposure metrics. The kernel density measure demonstrated more than a 2-fold (OR 2.51, 95% CI 2.00 - 3.15) increased risk of asthma ED presentation for the high exposure group compared to the low exposure group.ConclusionWe assessed exposure using traffic data from 2 independent sources and compared the results of 4 different exposure metric types. The results indicate that traffic congestion may be one of the most important aspects of traffic-related exposures, despite being overlooked in many studies on the exacerbation of asthma.

Effect of Protective Filters on Fire Fighter Respiratory Health: Field Validation During Prescribed Burns

BACKGROUND Bushfire smoke contains a range of air toxics. To prevent inhalation of these toxics, fire fighters use respiratory equipment. Yet, little is known about the effectiveness of the equipment on the fire ground. Experimental trials in a smoke chamber demonstrated that, the particulate/organic vapor/formaldehyde (POVF) filter performed best under simulated conditions. This article reports on the field validation trials during prescribed burns in Western Australia. METHODS Sixty-seven career fire fighters from the Fire and Emergency Services Authority of Western Australia were allocated one of the three types of filters. Spirometry, oximetry, self-reported symptom, and personal air sampling data were collected before, during and after exposure to bushfire smoke from prescribed burns. RESULTS Declines in FEV(1) and SaO(2) were demonstrated after 60 and 120 min exposure. A significant higher number of participants in the P filter group reported increases in respiratory symptoms after the exposure. Air sampling inside the respirators demonstrated formaldehyde levels significantly higher in the P filter group compared to the POV and the POVF filter group. CONCLUSIONS The field validation trials during prescribed burns supported the findings from the controlled exposure trials in the smoke chamber. Testing the effectiveness of three types of different filters under bushfire smoke conditions in the field for up to 2 hr demonstrated that the P filter is ineffective in filtering out respiratory irritants. The performance of the POV and the POVF filter appears to be equally effective after 2 hr bushfire smoke exposure in the field.

An Overview of Medical Geology Issues in Australia and Oceania

Australia and Oceania together make up some of the oldest and youngest geologic formations on the planet, ranging from rocks dating back to 4,400 million years to newly formed volcanic isles in the Pacific. The health issues related to these diverse geological materials range from those derived from exposure to metals and minerals to volcanic emissions including gas and ash, bushfires, dust storms, as well as health threats posed by natural hazards. With the position of a large part of this region within the Ring of Fire, many Australian and Oceanian lives are impacted upon by the forces related to tectonic movement, including earthquakes, tsunamis, and volcanic eruptions. There are also a number of medical geology issues related to the soil in this area. These include geophagy, melioidosis – an infectious disease caused by soil bacteria, and the impacts from ecosystem transformations caused by the disturbance of acid sulfate soils. An example of this is the increase of vector-borne mosquitoes carrying the Ross River virus with the formation of acidic ponds through acid sulfate soil oxidation. The potential adverse health outcomes from disturbing some parts of the land have long been acknowledged by traditional Aboriginal landowners of Australia, who refer to an area particularly rich in uranium and other metals as Sickness Country.

Understanding implementation of comprehensive geriatric care programs: a multiple perspective approach is preferred

Summary Background The Prevention and Reactivation Care Program (PReCaP) provides a novel approach targeting hospital‐related functional decline among elderly patients. Despite the high expectations, the PReCaP was not effective in preventing functional decline (ADL and iADL) among older patients. Although elderly PReCaP patients demonstrated slightly better cognitive functioning (Mini Mental State Examination; 0.4 [95% confidence interval (CI) 0.2–0.6]), lower depression (Geriatric Depression Scale 15; –0.9 [95% –1.1 to –0.6]), and higher perceived health (Short‐form 20; 5.6 [95% CI 2.8–8.4]) 1 year after admission than control patients, the clinical relevance was limited. Therefore, this study aims to identify factors impacting on the effectiveness of the implementation of the PReCaPand geriatric care ‘as usual’. Methods We conducted semi‐structured interviews with 34 professionals working with elderly patients in three hospitals, selected for their comparable patient case mix and different levels of geriatric care. Five non‐participatory observations were undertaken during multidisciplinary meetings. Patient files (n = 42), hospital protocols, and care plans were screened for elements of geriatric care. Clinical process data were analysed for PReCaP components. Results The establishment of a geriatric unit and employment of geriatricians demonstrates commitment to geriatric care in hospital A. Although admission processes are comparable, early identification of frail elderly patients only takes place in hosptial A. Furthermore, nursing care in the hospital A geriatric unit excels with regard to maximizing patient independency, an important predictor for hospital‐related functional decline. Transfer nurses play a key role in arranging post‐discharge geriatric follow‐up care. Geriatric consultations are performed by geriatricians, geriatric nurses, and PReCaP case managers in hospital A. Yet hospital B consultative psychiatric nurses provide similar consultation services. The combination of standardized procedures, formalized communication channels, and advanced computerization contributes significantly to geriatric care in hospital B. Nevertheless, a small size hospital (hospital C) provides informal opportunities for information sharing and decision making, which are essential in geriatric care, given its multidisciplinary nature. Conclusions Geriatric care for patients with multimorbidity requires a multidisciplinary approach in a geriatric unit. Geriatric care, which integrates medical and reactivation treatment, by means of early screening of risk factors for functional decline, promotion of physical activity, and adequate discharge planning, potentially reduces the incidence of functional decline in elderly patients. Yet low treatment fidelity played a major role in the ineffective implementation of the PReCaP. Treatment fidelity issues are caused by various factors, including the complexity of projects, limited attention for implementation, and inadequate interdisciplinary communication.
