The effectiveness of continuing professional development for the residential long-term care workforce: A systematic review

OBJECTIVES

To investigate the effectiveness of continuing professional development in residential long-term care.

DESIGN

Systematic review.

DATA SOURCES

PubMed, Cumulative Index to Nursing & Allied Health (CINAHL), and Web of Science.

REVIEW METHODS

Empirical studies published between 2003 and 2023 describing the effectiveness of continuing professional development in long-term care were selected according to PRISMA guidelines. The type, topic, and effectiveness of continuing professional development activities in long-term care were analysed, in addition to facilitators and barriers. The protocol of this review is registered in PROSPERO.

RESULTS

A total of 155 studies were selected, including over 17,000 participants the majority of whom were nurses. The most common topics were 'dementia care' (n = 22; 14.2 %), and restraint use (n = 14; 9 %). The impact of continuing professional development was mainly evaluated in terms of 'participant satisfaction with continuing professional development' (n = 5; 3 %), 'staff knowledge' (n = 57; 37 %), 'staff competencies and skills' (n = 35; 23 %), 'resident outcomes' (n = 45; 29 %), and 'staff wellbeing' (n = 12; 8 %). A total of 64 (41 %) studies evaluated if impact of continuing professional development was sustained over time. 'Good organisation', 'a supportive learning environment', 'expressing personal preferences', and 'management support' were described as facilitators of continuing professional development.

CONCLUSIONS

Increasing numbers of long-term care residents with complex health conditions require nurses with advanced skills, such as dementia care. To improve the effectiveness of continuing professional development, support from managers, who adopt relational leadership styles, is instrumental to integrate new knowledge and skills into practice. This needs to be linked to career progression, and consequently increase the attractiveness of working in the long-term care sector. This could meet the dual goal of improving outcomes for residents and nurses' job satisfaction.

The experience and attitudes of long-term care workers with teaching and learning modalities for the delivery of continuing professional development activities: a mixed-methods study

AIM

to develop a better understanding of the attitudes and experiences of healthcare workers and managers with face-to-face, online asynchronous (pre-recorded), and online synchronous (live) modalities for Continuing Professional Development (CPD) working in the Long-Term Care (LTC) sector.

BACKGROUND

The recent global pandemic significantly interrupted the delivery and organisation of education and training for healthcare professionals internationally. As a result of the restrictions, healthcare professionals' access to CPD was limited, consequentially education and training activities were mostly delivered online. Research into the experiences of healthcare workers with the various teaching and learning modalities in the LTC setting is limited.

DESIGN

An explanatory mixed methods study using an exploratory sequential design.

METHODS

A two-phase study conducted from January 2022 to September 2022, in the Republic of Ireland. In phase one, researchers conducted four focus groups and in phase two 168 participants completed a survey to explore the results of phase one.

RESULTS

From the focus groups interviews five themes emerged regarding participants' experiences, attitudes and preferences with the three modalities of CPD education and training in the field of LTC: 1) Flexibility, 2) Networking, 3) Resources and Support, 4) Engaging and meaningful learning, and 5) Balancing online and face-to-face learning through Blended Learning. Results from the survey found the preferred modality was face to face (n = 54, 32.1%), followed very closely by blended learning (n = 51, 30.4%). Most of the respondents reported that synchronous online CPD education was convenient, flexible, offers the opportunity to interact with peers, and that its quality depends on educators' skills. The majority of respondents (n = 155, 92.3%) declared that they would require support in the workplace to implement their new knowledge and skills.

CONCLUSIONS

This study revealed the significance participants place on 'engagement' when taking part in education and training. Engagement was described as a key factor to improve the delivery of CPD in the LTC setting. In addition, regardless of the mode of delivery, participants reported that they need to be supported in the workplace to implement their new knowledge and skills. This requires the support and endorsement of employers and managers, who could ensure more protected time for learning, technical support and championing facilitators and mentors in the workplace to enhance the translation of new knowledge into clinical practice.

TWEETABLE ABSTRACT

In LTC settings, face-to-face CPD is the preferred mode of delivery. Although synchronous online CPD is very convenient, educators must be able to engage learners. LTC workers need support by managers to implement their new knowledge and skills in their workplace.

Teaching and learning modalities for continuing professional development in the long-term care: A rapid synthesis review

AIM

To describe the various teaching and learning modalities for the delivery of Continuing Professional Development activities for health care professionals in the long-term care sector.

BACKGROUND

Continuing Professional Development is a key activity that organisations undertake to achieve effective workforce planning, recruitment, retention and upskilling strategies in long-term care settings. During the Covid-19 pandemic there was a rapid move to online modalities of Continuous Professional Development, but there is a paucity of evidence in relation to their effectiveness compared with face-to-face, or in-class learning.

DESIGN

A rapid synthesis review.

METHODS

MEDLINE, CINAHL and HEALTH BUSINESS ELITE databases were used to identify relevant articles that were published between 2016 and 2022. Original studies of any design investigating Continuing Professional Development activities, with or without a comparison between interventions or activities were included. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) was followed. The Kirkpatrick model was adopted as a globally recognised method for evaluating training programmes.

RESULTS

After a full text analysis, 34 papers were included in the review. Face to face was the most common method of delivery followed by online, while blended (a mix of face-to-face and online delivery) was the least common method used. The teaching modalities were not associated with specific learning contents, but were used for a range of content. Most studies obtained positive outcomes following implementation of the educational interventions. Kirkpatrick Level 4 (results) was the most commonly measured outcome.

CONCLUSIONS

While blended learning was the least common method of delivery, it was found to be more beneficial for learners than face-to-face or online exclusively. There are now new spaces to learn and new technologies that allow us to 'reimagine' where, when and how we teach. This requires Continuing Professional Development providers to design and tailor their courses according to health professionals' learning needs and the clinical contexts where they work. We recommend that Continuing Professional Development providers involve employers when designing teaching and learning activities for Long Term Care workers, to decide which modalities enable effective knowledge translation.

Development of a European Centre of Excellence (Coe) for Research in Continuing Professional Development (UPGRADE)

The European Centre of Excellence (CoE) for Research in Continuing Professional Development (UPGRADE) is a pan-European network of researchers, clinicians, regulators, educators, and professional bodies, established in 2020 through a consensus group of experts, who defined its mission, vision, values, aims and objectives. The Centre's aim is to advance the science of Continuing Professional Development (CPD) for healthcare professionals through research and dissemination of best practices for CPD. Debate among UPGRADE partners and interchange of research data will yield best practices across countries to optimise quality CPD programmes. Collaboration, information exchange and communication among CPD experts will be facilitated through UPGRADE via an online Community of Inquiry (CoI). UPGRADE aims to evolve as a driving force network of academics and health professional leaders in research, education, professional regulation, and clinical practice whose collaborative work ensures quality and safe person-centred care. UPGRADE members are from 22 European countries, represented by strategic leaders in diverse sectors of health, policy, academia, and professional organisations. Three research-working groups constitute the pillars of UPGRADE, which addresses gaps in research, collect and create critical databases, and solidify the effectiveness of CPD.

Early detection and recovery of river herring spawning habitat use in response to a mainstem dam removal

Historical loss of river and stream habitats due to impassable dams has contributed to the severe decline of many fish species. Anadromous fishes that migrate from the sea to freshwater streams to spawn have been especially impacted as dams restrict these fish from accessing ancestral spawning grounds. In 2018, Bloede Dam was removed from the Patapsco River near Baltimore, Maryland, restoring approximately 100 km of potential habitat for migratory fish. We assessed the response of anadromous river herring, alewife (Alosa pseudoharengus) and blueback herring (Alosa aestivalis), to this dam removal by monitoring environmental DNA (eDNA) and eggs from 2015 to 2021 at locations upstream and downstream of the dam site during their spawning migrations. We additionally assessed the presence of fish by collecting electrofishing samples and tracked the movements of individual adult fish within the river using passive integrated transponder (PIT) tags. No adult river herring, eDNA, or eggs were detected upstream of Bloede Dam in the four years prior to its removal despite the presence of a fish ladder. Our results suggest initial habitat use recovery by spawning river herring in the first year post-removal, although a relatively small proportion of the population in the river used the newly accessible habitat. In the three years post-removal, the likelihood of detecting river herring eDNA upstream of the former dam site increased to 5% for alewife and 13% for blueback herring. Two adult fish were also collected in electrofishing samples upstream of the dam site in 2021. We found no evidence of changes in egg abundance and no tagged fish were detected upstream of the dam site post-removal. While long term monitoring is needed to assess population changes, this study highlights the value of integrating methods for comprehensive understanding of habitat use following dam removal.

Economic evaluation of CPD activities for healthcare professionals: A scoping review

CONTEXT

Continuing professional development (CPD) activities for healthcare professionals are central to the optimisation of patient safety and person-centred care. Although there is some evidence on the economics of healthcare professionals training, very little is known about the costs and benefits of CPD.

METHODS

This study aimed to review the research evidence on economic evaluations of CPD activities for healthcare professionals. CINAHL, MEDLINE/PubMed, Scopus, Econlit and Web of Science databases were used to identify articles published between 2010 and 2021.

RESULTS

Of the 6791 titles identified, 119 articles met the inclusion criteria and were included in this scoping review. The majority of articles were partial economic evaluations of CPD programmes (n = 70); half were from the USA. Studies that included multiple professions were most prevalent (n = 54), followed by nurses (n = 34) and doctors (n = 23). Patient outcomes were the most commonly reported outcome (n = 51), followed by change in clinical practice (n = 38) and healthcare professionals' knowledge gain (n = 19).

CONCLUSIONS

There is an urgent call for more evidence regarding the economic evaluations of CPD. This is particularly important in view of the rising costs of healthcare globally. The majority of studies included in this review did not provide detailed information on the evaluations and many focused exclusively on the cost of CPD activities rather than outcomes.

Evaluation of prognostic risk models for postoperative pulmonary complications in adult patients undergoing major abdominal surgery: a systematic review and international external validation cohort study

BACKGROUND

Stratifying risk of postoperative pulmonary complications after major abdominal surgery allows clinicians to modify risk through targeted interventions and enhanced monitoring. In this study, we aimed to identify and validate prognostic models against a new consensus definition of postoperative pulmonary complications.

METHODS

We did a systematic review and international external validation cohort study. The systematic review was done in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched MEDLINE and Embase on March 1, 2020, for articles published in English that reported on risk prediction models for postoperative pulmonary complications following abdominal surgery. External validation of existing models was done within a prospective international cohort study of adult patients (≥18 years) undergoing major abdominal surgery. Data were collected between Jan 1, 2019, and April 30, 2019, in the UK, Ireland, and Australia. Discriminative ability and prognostic accuracy summary statistics were compared between models for the 30-day postoperative pulmonary complication rate as defined by the Standardised Endpoints in Perioperative Medicine Core Outcome Measures in Perioperative and Anaesthetic Care (StEP-COMPAC). Model performance was compared using the area under the receiver operating characteristic curve (AUROCC).

FINDINGS

In total, we identified 2903 records from our literature search; of which, 2514 (86·6%) unique records were screened, 121 (4·8%) of 2514 full texts were assessed for eligibility, and 29 unique prognostic models were identified. Nine (31·0%) of 29 models had score development reported only, 19 (65·5%) had undergone internal validation, and only four (13·8%) had been externally validated. Data to validate six eligible models were collected in the international external validation cohort study. Data from 11 591 patients were available, with an overall postoperative pulmonary complication rate of 7·8% (n=903). None of the six models showed good discrimination (defined as AUROCC ≥0·70) for identifying postoperative pulmonary complications, with the Assess Respiratory Risk in Surgical Patients in Catalonia score showing the best discrimination (AUROCC 0·700 [95% CI 0·683-0·717]).

INTERPRETATION

In the pre-COVID-19 pandemic data, variability in the risk of pulmonary complications (StEP-COMPAC definition) following major abdominal surgery was poorly described by existing prognostication tools. To improve surgical safety during the COVID-19 pandemic recovery and beyond, novel risk stratification tools are required.

Fracture liaison services in Ireland-how do we compare to international standards?

In this first na tional survey of public hospitals in The Republic of Ireland, we found fracture liaison services (FLS) to be heterogeneous, limited in many cases and poorly supported. A national strategy is urgently needed to support the implementation and operation of an FLS, and thus help reduce the burden of fragility fractures for patients and the healthcare system.

INTRODUCTION

Fragility/low-trauma fractures are a global concern, whose incidence is rising as the population ages. Many are preventable, and people with a prior fragility fracture are at particularly high risk of further fractures. This patient group is the target of the International Osteoporosis Foundation (IOF) Capture the Fracture campaign, advocating global adoption of fracture liaison services (FLS), with the aim of preventing secondary fragility fractures. We wished to determine the current availability and standards of an FLS in Ireland, ahead of the launch of a National FLS database.

METHODS

We devised a questionnaire encompassing the thirteen IOF standards for an FLS and asked all 16 public hospitals with an orthopaedic trauma unit in Ireland, to complete for the calendar year 2019 in patients aged ≥ 50 years.

RESULTS

All sites returned the questionnaire, i.e. 100% response rate. Nine hospitals stated that they have an FLS, additionally one non-trauma hospital running a FLS responded, and were included. These 10 FLS had identified and managed 3444 non-hip fractures in the year 2019. This figure represents 19% of the expected non-hip fragility fracture numbers occurring annually in Ireland. Implementation of the IOF standards was very variable. All sites reported being inadequately resourced to provide a high-quality service necessary to be effective.

CONCLUSION

The existence and functioning of FLS in Ireland are heterogeneous and suboptimal. A national policy to support the implementation of this programme in line with international standards of patient care is urgently needed.

Change in a clinical measure of cervical movement sense following four weeks of kinematic training

BACKGROUND

Training targeted towards improving cervical movement accuracy is an effective strategy in the management of neck pain. Relatively complex measures have been validated to measure this in research although a simple clinical measure using a head mounted laser tracing a standardised pattern has been shown to be reliable. It is not known if this method demonstrate clinically meaningful change to training.

OBJECTIVE

To assess change responsiveness of the clinical cervical movement sense (CCMS) test following home kinematic training (KT).

STUDY DESIGN

Pre-post treatment observational study.

METHODS

The CCMS measure was assessed in 56 patients with chronic neck pain (41 intervention, 15 control) at baseline and 4 weeks post intervention by blinded assessors. Task completion time and error number were assessed reviewing video of the performances. Change pre-post intervention was compared between groups.

RESULTS

There was a significantly greater mean improvement in the intervention (-9.2 ± 9.3) seconds) for completion time and combined time and error (-13.3 ± 16) compared to the control group for time (-2.0 ± 9.8) and combined time and error (-1.8 ± 14) with moderate to high effect sizes (Cohen's d 0.76). There was a non-significant trend for decreased number of errors in the intervention (-4.1 ± 9.0) compared to control group (0.2 ± 8.3).

CONCLUSION

Completion time of the CCMS test appears to be able to demonstrate meaningful change following four weeks of KT. This further supports its clinical utility as a measure of cervical movement accuracy and provides direction for future clinical use.

Tracheostomy stomal seeding following oral cavity resection

BACKGROUND

Tracheal stoma recurrence following oral cavity surgery is exceedingly rare. Although several different mechanisms for this have been described, the pathogenesis still remains uncertain.

METHODS

We present the case of a gentleman who presented 6-months following oral cavity SCC resection with a large fungating mass at his previous tracheostomy site, and also review the reported literature on this rare phenomenon.

RESULTS

Four weeks after diagnosis of his recurrence he underwent a total laryngectomy, wide-local skin excision and reconstruction with a pectoralis major pedicled flap. He recovered well initially following his operation, however unfortunately contracted nosocomial SARS-Cov2 and succumbed from respiratory complications during his post-operative recovery.

CONCLUSION

Stomal recurrence after temporary tracheostomy for oral cavity malignancies are very rare. Previously reported management of these can vary from surgical to palliative treatment. Methods to prevent these include delaying tracheostomy until after surgical resection, packing the pharynx during resection and adjuvant radiotherapy.

Neonatal screening programme for CF: Results from the Irish Comparative Outcomes Study (ICOS)

The introduction of NBS in Ireland in July 2011, provided a unique opportunity to investigate clinical outcomes using a comparative historical cohort study. Clinical cohort: children clinically diagnosed with CF born 1 July 2008 to 30 June 2011, and NBS cohort: children diagnosed with CF through NBS born 1 July 2011 to 30 June 2016. Clinical data were collected from the CF Registry of Ireland, medical charts, and data on weight/height before diagnosis from public health nurses and family doctors. SPSS was used for analysis. A total of 232 patients were recruited (response 93%) (93 clinically diagnosed, 139 NBS-detected). Following exclusions of meconium ileus (MI) (40), diagnosis outside Ireland (4), and being designated as CFSPID (2), a total of 77 clinically diagnosed patients and 109 NBS detected children were included in analysis. Over half were homozygous for F508del mutation. Being clinically diagnosed was independently associated with hospitalization for infective exacerbation of CF < 36 months (OR, 2.80; 95%CI 1.24-6.29). Diagnosis to first acquisition of Pseudomonas aeruginosa was significantly longer in NBS than clinically detected; from birth there was no significant difference. Weight and length/height were significantly greater in NBS cohort at 6 and 12 months. We provide evidence of improved growth, reduced hospitalization for acute exacerbations, and delayed P. aeruginosa acquisition (from diagnosis) to age 3 for the NBS cohort. Screening practices likely account for the non-significant difference in P. aeruginosa acquisition from birth.

Parental awareness of newborn bloodspot screening in Ireland

BACKGROUND

There is little known regarding how familiar parents are with the newborn bloodspot screening (NBS) test or how well parents of a child with a screen-detected condition understand that condition initially.

AIM

The study aim was to examine parental NBS awareness and conditions screened.

METHODS

Two studies were conducted: [1] Parents of children with cystic fibrosis (CF) detected via NBS and subsequently, diagnosed (n = 124) completed a telephone questionnaire regarding information they received at the time of NBS. [2] A cross-sectional study of women (n = 662 (58%) antenatal; n = 480 (42%) postnatal) attending three large maternity hospitals completed a questionnaire addressing NBS awareness.

RESULTS

Mothers incorrectly identified diabetes/asthma (35% postnatal; 70% antenatal) and sickle cell disease (26%) as conditions on NBS in Ireland. Phenylketonuria was correctly identified by 48/26%, CF by 82/64%, and congenital hypothyroidism by 35/13% postnatal and antenatal women respectively. Of parents of children screen-detected and subsequently, diagnosed with CF, only half (n = 63; 51%) reported awareness at the time of NBS that CF was included. These results should be used to improve the information provided to expectant mothers and to inform health professionals' initial discussions with parents about their child's diagnosis, building on parents' pre-existing knowledge.

An evaluation of pregnant women's knowledge and attitudes about newborn bloodspot screening

OBJECTIVES

research suggests that information provided to parents about newborn bloodspot screening (NBS) can be inconsistent. The majority of international NBS programmes recommend that parents should receive information about NBS in the antenatal period, however prior studies have mostly focused on postnatal women's knowledge, with no quantitative study of women's knowledge in the antenatal period conducted to date. Thus, the aim of this study was to determine if antenatal women received information about NBS in the antenatal period and to evaluate their knowledge and attitudes about NBS.

DESIGN/PARTICIPANTS

we conducted a cross-sectional study among antenatal attendees at three maternity hospitals in Ireland. A total of 662 antenatal women (≥36 weeks gestation) were recruited into the study (279 primiparous, 368 multiparous). Women were asked to complete a self reported knowledge and attitude questionnaire about NBS.

FINDINGS

primiparity (OR 2.75; 95% CI 1.65, 4.59) lower educational status (OR 1.79; 95% CI 1.02, 3.15) and not having private health insurance (OR 1.84; 95% CI 1.19, 2.85) were independently associated with poor NBS knowledge. Fourteen per cent of antenatal women recalled receiving an information leaflet about NBS, yet over 87 % reported that they would like more information. Thirty four per cent of women agreed that they understand everything they need to know about NBS.

CONCLUSIONS/IMPLICATIONS FOR PRACTICE

the process of providing women with information about NBS in the antenatal period is inconsistent; consequently their awareness about NBS is limited. To make an informed choice about NBS women require information to be provided in a more structured format. There are many missed opportunities in the antenatal period for maternity care providers to provide women with information about NBS. Our study recommends that healthcare providers should have a more formal and structured approach with regard to the provision of information about NBS in the antenatal period. This could be achieved by incorporating NBS education into antenatal education classes or through multimedia while women are waiting in the antenatal clinic. Healthcare providers may need education about the importance and benefits of providing women with information about NBS in the antenatal period.

Light intensity impacts the production of biofuel intermediates in Heterosigma akashiwo growing on simulated flue gas containing carbon dioxide and nitric oxide

As a potential biofuel feedstock, the marine microalga, Heterosigma akashiwo, accumulates significant lipids, is capable of long-term growth in outdoor photobioreactors, and is an excellent candidate for the bioremediation of industrial emissions. Here, we evaluated resource partitioning in H. akashiwo growing on a CO2 and NO gas mixture under three light intensities: 160, 560, or 1200μmolquantam(-2)s(-1). Light levels had no effect on growth; however, cultures in high light accumulated 2.3-fold more carbohydrates and 17% fewer lipids. Light levels did not affect the percentage of saturated fatty acids, but mono-unsaturates increased by 6% and poly-unsaturates decreased by 12% in high light. The fatty acid profiles reported here suggest that H. akashiwo is a good candidate for the production of neutral lipids for biodiesel and also omega-3 fatty acids, and that the quality of biodiesel acquired from feedstocks grown under fluctuating light conditions would be relatively stable.

Airflow through Polyurethane Foams with Near-Circular Cell-Face Holes

A range of open-cell slow-recovery polyurethane (PU) foams were found to have roughly circular cell-face holes, which are small compared with the face area. The pressure gradient through the foam was measured for airflow velocities in the range 0.5–5ms 1, and the permeabilities K and inertial flow coefficients B calculated. Computational Fluid Dynamics (CFD) was used for laminar airflow through both an axisymmetric model and a regular Kelvin foam model. The predicted foam permeabilities from the latter were close to the experimental values. Finite Element Analysis (FEA) was used to predict cell-face shape changes under a pressure gradient. The distorted face shapes were then used in the CFD model to explain why the B values were negative for some foams.

Rapid identification and antimicrobial susceptibility testing of positive blood cultures using MALDI-TOF MS and a modification of the standardised disc diffusion test: a pilot study

AIMS

In an era when clinical microbiology laboratories are under increasing financial pressure, there is a need for inexpensive, yet effective, rapid microbiology tests. The aim of this study was to evaluate a novel modification of standard methodology for the identification and antimicrobial susceptibility testing (AST) of pathogens in positive blood cultures, reducing the turnaround time of laboratory results by 24 h.

METHODS

277 positive blood cultures had a Gram stain performed and were subcultured and incubated at 37°C in a CO2 atmosphere for 4-6 h. Identification of the visible growth was performed using matrix-assisted laser desorption time of flight mass spectrometry (MALDI-TOF MS). Taking a modified approach to the Clinical and Laboratory Standards Institute-standardised AST methodology, an inoculum density of 0.5 McFarland was prepared from the early growth for disc diffusion testing. The standard AST method was also performed on the 18-24 h culture.

RESULTS

96% (n=73/76) of gram-negative organisms were correctly identified by MALDI-TOF MS. Comparative analysis of the rapid and standard AST results showed an overall interpretive category error rate of 7.7% (6.7% minor errors, 0.6% major errors and 0.4% very major errors). 100% of Staphylococcus aureus (n=41) and enterococcus isolates (n=9) were correctly identified after 4-6 h incubation. The overall AST categorical agreement was also 100% for these isolates.

CONCLUSIONS

An incubation of 4-6 h directly from positive blood cultures allowed for both a rapid species identification and an antimicrobial susceptibility result approximately 24 h earlier than is possible using standard methodology.

Components of the Risk Instrument for Screening in the Community (RISC) that Correlate with Public Health Nurses' Perception of Risk

BACKGROUND

Functional decline and frailty are common in community-dwelling older adults, leading to an increased risk of adverse outcomes.

OBJECTIVE

To examine the factors that public health nurses perceive to cause risk of three adverse outcomes: institutionalisation, hospitalisation, and death, in older adults, using the Risk Instrument for Screening in the Community (RISC).

DESIGN

A quantitative, correlational, descriptive design was used.

SETTING AND PARTICIPANTS

A sample of 803 community-dwellers, aged over 65 years receiving regular follow-up by public health nurses. Procedure and Measurements: Public health nurses (n=15) scored the RISC and the Clinical Frailty Scale (CFS) on patients in their caseload. We examined and compared correlations between the severity of concern and ability of the caregiver network to manage these concerns with public health nurses' perception of risk of the three defined adverse outcomes.

RESULTS

In total, 782 RISC scores were available. Concern was higher for the medical state domain (686/782,88%) compared with the mental state (306/782,39%) and activities of daily living (595/782,76%) domains. Concern was rated as severe for only a small percentage of patients. Perceived risk of institutionalisation had the strongest correlation with concern over patients mental state,(r=0.53), while risk of hospitalisation,(r=0.53) and death,(r=0.40) correlated most strongly with concern over the medical state. Weaker correlations were found for the other domains and RISC scores. The CFS most strongly correlated with the ADL domain,(r=0.78).

CONCLUSION

Although the prevalence of concern was high, it was mostly rated as mild. Perceived risk of institutionalisation correlated most with concern over the ability of caregiver networks to manage patients' mental state, while risk of hospitalisation and death correlated with patients' medical state. The findings suggest the importance of including an assessment of the caregiver network when examining community-dwelling older adults. Validation of the RISC and public health nurses' ratings are now required.

Newborn bloodspot screening for cystic fibrosis: What do antenatal and postnatal women know about cystic fibrosis?

BACKGROUND

The Republic of Ireland has one of the highest reported incidences of cystic fibrosis (CF) in the world (1/1353) with an estimated carrier rate of 1/20. No cure exists, however there have been significant advances in available treatments. Newborn bloodspot screening (NBS) for CF was added to the NBS programme in Ireland in July 2011. Little is known about antenatal or postnatal women's knowledge about CF.

METHODS

This was a cross-sectional study of 662 antenatal (≥36weeks gestation) and 480 postnatal women (post NBS). Women were asked to self-complete a questionnaire including 14 CF knowledge questions.

RESULTS

Among the respondents significantly more postnatal than antenatal women were aware that CF is included on the NBS (81.8% vs 63.5%; p<0.001). 92.7% believe that there are health consequences to being a carrier and 33.6% believe there is a cure for CF. In the multivariate analysis, lower educational status (OR 2.13; 95% CI 1.31, 3.46) being an antenatal mother (OR 1.51; 95% CI 1.04, 2.18), having no family history of CF (OR 5.82; 95% CI 1.62, 20.90) were associated with poor CF knowledge, while increasing age was found to be protective against poor CF knowledge (OR 0.96; 95% CI 0.92, 0.99).

CONCLUSIONS

Results from this study provide a useful insight into women's preexisting knowledge about CF, which could be used to inform initial discussions with parents about their child's diagnosis.

Direct imaging of changes in aerosol particle viscosity upon hydration and chemical aging

We report quantitative, real-time, online observations of microscopic viscosity changes in aerosol particles of atmospherically relevant composition, using fluorescence lifetime imaging (FLIM) of viscosity.

Organic aerosol particles (OA) play major roles in atmospheric chemistry, climate, and public health. Aerosol particle viscosity is highly important since it can determine the ability of chemical species such as oxidants, organics or water to diffuse into the particle bulk. Recent measurements indicate that OA may be present in highly viscous states, however, diffusion rates of small molecules such as water are not limited by these high viscosities. Direct observational evidence of kinetic barriers caused by high viscosity and low diffusivity in aerosol particles were not available until recently; and techniques that are able to dynamically quantify and track viscosity changes during atmospherically relevant processes are still unavailable for atmospheric aerosols. Here we report quantitative, real-time, online observations of microscopic viscosity changes in aerosol particles of atmospherically relevant composition, using fluorescence lifetime imaging (FLIM) of viscosity. We show that microviscosity in ozonated oleic acid droplets and secondary organic aerosol (SOA) particles formed by ozonolysis of myrcene increases substantially with decreasing humidity and atmospheric oxidative aging processes. Furthermore, we found unexpected heterogeneities of microviscosity inside individual aerosol particles. The results of this study enhance our understanding of organic aerosol processes on microscopic scales and may have important implications for the modeling of atmospheric aerosol growth, composition and interactions with trace gases and clouds.

Paediatric tonsillotomy--an Irish perspective on potential evolving indications

Tonsillotomy is the preferred treatment of some otolaryngologists for younger patients (under 3 years) with low body weight (under 15 kgs) and a history of obstructive sleep apnoea. The use of the technique in the same patient cohort for recurrent tonsillitis remains controversial. The aim of this study was to evaluate the indications and outcomes of paediatric patients undergoing tonsillotomy (with or without adenoidectomy) at a paediatric ENT centre in Ireland. Patients were identified from a prospectively maintained database and chart review was completed. A total of 23 patients were identified who underwent tonsillotomy. The commonest indication was Obstructive Sleep Apnoea (OSA) in 15 patients (65%). Outcomes following tonsillotomy compared favourably with traditional tonsillectomy. No intra-operative or post-operative complications were recorded (0%). No patients required readmission or later tonsillectomy (0%). At follow-up 19/23 patients with OSA (82.6%) had complete symptom resolution. Tonsillotomy appears to represent a safe, effective treatment option in the paediatric population, however, its role in recurrent tonsillitis remains controversial.

A case of quinsy following high-pressure water jet injury

High-pressure water injuries of the oropharynx are uncommon but can cause significant injury and airway compromise when they occur. A small number of cases of high-pressure water injury of the oropharynx have been presented in the literature, detailing a range of effects and outcomes. We describe the first reported case of high-pressure water injury of the oropharynx associated with peritonsillar abscess (quinsy) requiring surgical drainage.

Discharging fused silica optics occluded by an electrostatic drive

Charge accumulation on test masses is a potentially limiting noise source for gravitational-wave interferometers, and may occur due to exposure to an electrostatic drive (ESD) in modern test mass suspensions. We verify that an ESD can cause charge accumulation on a fused silica test mass at a rate of 8 × 10(-16) C/cm(2)/h. We also demonstrate a charge mitigation system consisting of a stream of nitrogen ionized by copper feedthrough pins at 3750 VAC. We demonstrate that the system can neutralize positive and negative charge from 10(-11) C/cm(2) to 3 × 10(-14) C/cm(2) in under 2 h.

Impact of irinotecan and oxaliplatin on overall survival in patients with metastatic colorectal cancer: a population-based study

P2-16-11: Role of Proper Patient Counselling in Combination with Effect of Socioeconomic Deprivation on the Rate of Immediate Breast Reconstruction after Mastectomy

Introduction: current guidelines in the United Kingdom suggest that the possibility of breast reconstruction should be discussed with all patients prior to mastectomy. However, the majority of patients are still treated with mastectomy alone and no reconstruction is carried out. It has also been suggested that women from more deprived areas are less likely to undergo immediate breast reconstruction (IBR). We investigated potential pitfalls in patient counselling and consequent decision making contributing to present IBR rate in combination with the effect of socioeconomic deprivation.

Methods: data from 89 consecutive mastectomy patients was prospectively collected in a single centre in Glasgow between August 2010 and March 2011. Each patient was scored for deprivation based on The Scottish Index of Multiple Deprivation. The patients were then divided into two groups: high and low deprivation levels. Consultations about IR and patients’ acceptance of counselling were analysed. For statistical calculations Fischer's exact test was applied. Results: IBR was offered to 41 (46%) patients, but it was not to 42 (47%) (6 were excluded due to incomplete data). 25 patients accepted IBR, and of those 24 (27%) underwent IBR. 16 of 41 patients refused to undergo IBR due to lack of interest (10), not feeling ready for it (2), preference of delayed procedure (2) and fear of delaying adjuvant therapy (2). Of 42 patients whom IBR was not offered, only 10 were documented in the notes, while there was no reference for discussing reconstruction in 32 (36%) cases. Reasons for not even discussing reconstruction were the following: age (15), co-morbidities (18), locally advanced cancer (2), co-morbidities with age (5), and locally advanced cancer with age (2). As regards to socioeconomic deprivation; 44 (49%) patients were from deprived areas and 39 (44%) from affluent areas. 41 patients were offered IBR and of these 23 (26%) were from affluent areas compared to 18 (20%). Of the 42 patients who were not offered IR, 26 (29%) were from deprived while 16 (18%) from affluent areas (p&lt;0.05). Of the 44 deprived patients, 18 were offered IBR but 26 were not. 15 of 25 patients, who accepted IBR, were from affluent areas. The 16 patients who refused IBR had equal distribution of deprivation.

Conclusions: while none of the reasons for not offering IBR represent absolute contraindication to IBR, decisions about refusal are based mostly on patients’ subjective intuitions. Further, a greater proportion of the patients who were not offered IBR were from more deprived areas, and it seems that patients from affluent areas are more likely to be offered IBR compared to ones from deprived areas. However, confounding factors such as co-morbidities may contribute to the above. We believe, therefore, that detailed counselling about reconstruction of each patient requiring mastectomy is necessary, which is likely to further increase IBR rate.

Abstract P189: Evaluating the Effects of Free the Children on Students' Self-Efficacy, Eating Habits, and Activity Levels

Background: The National Center for Chronic Disease Prevention and Health Promotion reported in 2008, obesity was 19.6% in children ages 6-11 and 18.1% in children ages 12-19. Free The Children (FTC) was created by a 12 year-old student to promote healthy eating habits, physical activity, and community service in his peers. The program has grown in popularity and this study aims to evaluate its effect on middle school students who are directly and indirectly involved with FTC.

Methods: Middle school students from Project Healthy Schools, a school based intervention in southeast Michigan, completed surveys detailing their self-efficacy, eating habits, and activity levels. To determine the direct effect of FTC, only students in FTC schools were surveyed and comparisons were made between participating and non-participating students. To measure indirect effects of FTC, all students were surveyed, regardless of their involvement in FTC, and comparison made between students who attended FTC schools and those who did not. Statistical analysis was conducted using non-parametric, independent t-testing and chi-square analysis.

Results: In the second comparison, students at FTC schools ate better, exercised more, and also had higher self efficacy.

Conclusions: Students who attended schools offering FTC had better eating/activity habits and significantly higher self-efficacy ratings. Students that directly participated in the FTC program showed even better results for diet, activity and self-efficacy. These results suggest that the FTC program may have both a direct and indirect positive impact on health behaviors and emotional status in middle school students.
