Assessment of Answer-Changing Behavior of Nursing Students and Faculty Recommendations

BACKGROUND

Existing literature identifies a general positive benefit to students' examination scores when students change their answer on examinations. Current shifts toward computerized examinations and in test anxiety warrant a literature update on test-taking behaviors.

PURPOSE

This study assessed answer changing on multiple-choice examinations and investigated faculty recommendations related to answer changing.

METHOD

This study used a mixed-methods design using retrospective student data from ExamSoft reports and faculty responses from a national survey of nurse educators.

RESULTS

Findings indicated 55% of students improved their examination score, with an average improvement of 3%, and 24% of students lowered their examination score. However, faculty continue to incorrectly recommend that students should not change answers on examinations.

CONCLUSION

The results of this study support prior literature that answer changing benefits students. However, data are lacking on the characteristics of students who improve or lower their examination scores by changing answers.[J Nurs Educ. 2021;60(6):324-328.].

POS0128 PHYSICIAN AND PATIENT PERCEPTIONS OF SURGICAL PROCEDURES FOR KNEE OA ACROSS JAPAN, THE US AND 5 EU COUNTRIES: RESULTS OF A REAL-WORLD STUDY

Background:

Patients with knee osteoarthritis (OA) who do not achieve adequate pain relief and functional improvement with a combination of non-pharmacologic and pharmacologic therapies are recommended an arthroplasty as an effective option to relieve severe pain and functional limitations. However, some patients are reluctant to undergo surgical interventions, and clinicians may choose to avoid or delay surgery due to safety risks and/or the financial cost. It is of interest to understand if the use and perception of surgery differs between countries, however, few published data exist.

Objectives:

To demonstrate how surgery and the use of surgical procedures differs across Japan, United States of America (US) and 5 major European countries (EU5) and to evaluate patient perception towards surgery.

Methods:

Data were drawn from the Adelphi OA Disease Specific Programme (2017-18), a point-in-time survey of primary care physicians (PCP), rheumatologists (rheums), orthopaedic surgeons (orthos) and their OA patients. Patients with physician-diagnosed knee OA were included and segmented into two categories: had previous surgery (PS) and never had surgery (NS). A Fisher’s exact test was performed on the two groups. Physicians reported on patient demographics; whether patients had undergone surgery; type of surgery; success of surgery; how success was defined; and reasons for wanting to delay surgery. Patients reported their willingness to undergo surgery; reasons for not wanting surgery; how successful their surgery was; and how they defined this success.

Results:

Physician/patient reported data were available for 302,230 (Japan), 527,283 (US) and 1487,726 (EU5) patients with diagnosed knee OA. Patients were categorised by their physicians as mild (40% Japan; 34% US; 24% EU5), moderate (49% Japan; 49% US; 56% EU5) or severe (9% Japan; 17% US; 19% EU5). Patients in Japan were more likely to be female (78% vs 54% US; 58% EU5), older (73 vs 65 US; 66 EU5) and have a lower BMI than patients in the US and EU5. Obesity and diabetes were much less prevalent among patients in Japan. One in ten patients in Japan had undergone a surgery (10%), far fewer than in the US (22%) or EU5 (17%). When surgery was performed, this was more likely to be a total joint replacement (TJR) in Japan, whereas in the EU and US, arthroscopic washout was more commonly performed.

For over half of Japanese patients (56%), successful surgery was more likely to be defined as having no more pain (vs. 35% US; 14% EU5). Improved mobility and a reduction in pain were also commonly reported reasons. Physicians (in each region) were more likely to suggest pain reduction, rather than no pain, and improved mobility as markers of success. Patients in Japan were much more likely to say they would not agree to surgery if recommended by their doctor, or were unsure (84% vs. 68% US; 62% EU5). The main reason for patient reluctance in Japan was fear of surgery, whereas in the US and EU5 the main reason given was that surgery was not needed. This finding was also evident among physicians in Japan, who frequently reported that patient reluctance was a key reason for delaying surgery. Physicians in Japan, do however, report that patient request was one of their main triggers for recommending surgery (45% vs 20% US; 16% EU5).

Conclusion:

Although surgery can be an effective option for those with OA who have exhausted other treatment options, some patients are reluctant to undergo surgery out of fear, especially in Japan, possibly due to the higher patient age. Physicians aiming to delay surgery were driven by patient reluctance in Japan, whereas cost to patient was a bigger factor in the US and EU5. The higher level of TJR vs. other surgery options among patients in Japan may suggest physicians are looking for higher levels of efficacy.

Potent SARS-CoV-2 binding and neutralization through maturation of iconic SARS-CoV-1 antibodies

Antibodies against coronavirus spike protein potently protect against infection and disease, but whether such protection can be extended to variant coronaviruses is unclear. This is exemplified by a set of iconic and well-characterized monoclonal antibodies developed after the 2003 SARS outbreak, including mAbs m396, CR3022, CR3014 and 80R, which potently neutralize SARS-CoV-1, but not SARS-CoV-2. Here, we explore antibody engineering strategies to change and broaden their specificity, enabling nanomolar binding and potent neutralization of SARS-CoV-2. Intriguingly, while many of the matured clones maintained specificity of the parental antibody, new specificities were also observed, which was further confirmed by X-ray crystallography and cryo-electron microscopy, indicating that a limited set of VH antibody domains can give rise to variants targeting diverse epitopes, when paired with a diverse VL repertoire. Our findings open up over 15 years of antibody development efforts against SARS-CoV-1 to the SARS-CoV-2 field and outline general principles for the maturation of antibody specificity against emerging viruses.

POS0337 SOUTHEND PRE-TEST PROBABILITY SCORE AND HALO SCORE AS MARKERS FOR DIAGNOSIS AND MONITORING OF GCA: EARLY RESULTS FROM THE PROSPECTIVE HAS-GCA STUDY

Background:

EULAR recommends doppler ultrasound (US) as the first line imaging in patients with Giant Cell Arteritis (GCA) suspect. Traditionally, US non-compressive halo sign has been used for diagnosis but prospective studies on response and disease monitoring are lacking

Objectives:

The HAS GCA study has the objective of prospectively assessing role of US in diagnosis, prognosis and monitoring in newly diagnosed GCA. We report early baseline and up to month 3 data on our current recruitment in a study that has suffered disruption from the pandemic

Methods:

HAS GCA (IRAS#264294) is an ongoing, prospective, multicentre study recruiting from referrals of suspected GCA to fast track clinics. The objective is to recruit 270 patients, including 68 GCA patients. Based on the Southend GCA clinical pre-test probability score (SPTPS)1, patients were stratified in to low, intermediate and high risk categories2. Temporal and axillary US Halo Scores were calculated from the halo thickness and extent in bilateral temporal arteries, parietal and frontal branches and axillary arteries. These individual scores were summed (TA Halo Score x1 plus; AA Halo Score x3) to generate a Total Halo Score (THS)3.

Mann Whitney U test and Fisher’s exact test were used to compare baseline features between GCA and controls. Wilcoxon signed rank test was used to evaluate disease features at baseline and at 3 months in GCA patients. Sensitivity (Sn) and Specificity (Sp) were calculated, where applicable. P value <0.05 is statistically significant

Results:

Ninety-three patients (29 GCA, 64 controls) have been recruited thus far: 18 completed 3-month follow up assessment; 4 were lost to follow up (2 died, 2 withdrew consent due to pandemic). Demographics, clinical features, and US results are shown (Table 1).

Table 1.

Among GCA patients, 23 had cranial, 2 large-vessel and 4 mixed phenotypes (cranial plus large vessel) disease.

Jaw claudication (66%) and polymyalgic symptoms (55%) were the dominant features in GCA patients. Median age 75 years in GCA (42% females) and 67 years in controls (78% females). GCA and controls were stratified by SPTPS to Low risk (0% vs 48%; Sn-undefined, Sp-97), Intermediate risk (24% vs 39%; Sn-100, Sp-100) and High risk (76% vs 13%; Sn-95, Sp-88). Optimal SPTPS cut-off point was ≥12 (Sn-93, Sp-86); ≥10 (Sn-100 & Sp-69).

Median THS was 21 in GCA and 6 in controls. Optimal cut-off Halo Score in diagnosis was TAHS ≥5 (Sn-90, Sp-98), AAHS ≥11 (Sn-55, Sp-80), THS ≥18 (Sn-72%, Sp-98%). Among the 18 patients who completed 3-months follow up, median TAHS, AAHS and THS reduced from 10 to 2.5, 12 to 6 and 21 to 10, respectively (Figure 1).

Conclusion:

Along with SPTPS, Halo Score successfully discriminates GCA from non GCA mimics. HS is effective in showing 3-month response and may be a useful marker to monitor GCA disease activity.

A grounded theory of clinical nurses' process of coping during COVID-19

AIMS AND OBJECTIVES

To explore clinical nurses' process of coping during COVID-19 and develop a grounded theory that can be used by leaders to support clinical nurses during a disaster.

BACKGROUND

The COVID-19 pandemic has provoked widespread disruption to clinical nurses' work. It is important to understand clinical nurses' processes of coping during disasters to support the nursing workforce during events such as global pandemics.

DESIGN

We employed the Corbin and Strauss variant of grounded theory methodology, informed by symbolic interactionism, and applied the EQUATOR guidelines for qualitative research publication (COREQ).

METHODS

Data collection entailed semi-structured interviews with experienced clinical nurses (n =20) across diverse settings. We analysed data by identifying key points in the nurses' coping processes inductively building concepts around these points.

RESULTS

The predictor of nurses' outcomes in this grounded theory was their confidence in their ability to cope during the pandemic. When nurses lacked confidence, they experienced working in the context of acute COVID-a state of chaos and anxiety, with negative consequences for nurses. However, when nurses were confident in their abilities to cope with the pandemic, they experienced working in the context of chronic COVID, a calmer state of acceptance. There were many workplace factors that influenced nurses' confidence, including adequacy of personal protective equipment, clear information and guidance, supportive leadership, teamwork and adequate staffing.

CONCLUSIONS

Understanding clinical nurses' experience of coping during COVID-19 is essential to maintain the nursing workforce during similar disasters.

RELEVANCE TO CLINICAL PRACTICE

Nurse leaders can target areas that support nurses' confidence, such as adequate PPE and staffing. In turn, increased confidence enables clinical nurses to cope during disasters such as a global pandemic.

What is nursing work? A meta-narrative review and integrated framework

BACKGROUND

There is ample evidence that modern nurses are under strain and that interventions to support the nursing workforce have not recognised the complexity inherent in nursing work. Creating a modern model of nursing work may assist nurses in developing workable solutions to professional problems. A new model may also foster cohesion among broad and diverse nursing roles.

AIM

The aim of this meta-narrative review was to investigate how researchers, using different methods and theoretical approaches, have contributed to the understanding of nursing work.

METHODS

A meta-narrative review was done to evaluate the trajectory of nursing work research, from 1953 to present. This review progressed through the stages of planning, searching, mapping, appraisal, and synthesis.

FINDINGS

A total of 121 articles were included in this meta-narrative review. These articles revealed five narratives of nursing work, where work is conceptualised as labour. These narratives were physical labour (n = 14), emotional (n = 53), cognitive (n = 24), and organisational (n = 1), and combinations of more than one type of labour (n = 29 articles). The paradigms identified in the meta-narrative were the positivist, interpretive, critical, and evidence-based paradigms. Each article in the review corresponded with a paradigm and a labour narrative, creating a comprehensive model.

CONCLUSIONS

Nursing work can be understood as a model of physical, emotional, cognitive, and organisational labour. These different types of labour may be hidden and taken for granted. Nurses can use this model to articulate what they do and how it supports patient safety. Nurses can also advocate for staffing allocations that consider all types of nursing labour. Tweetable abstract Nursing work is complex and includes physical, emotional, cognitive, and organisational labour. Staffing needs to take all nursing labour into account.

Safety of Inpatient Dofetilide Initiation per Cardiology Services: A Retrospective Review

INTRODUCTION

Dofetilide is an antiarrhythmic medication that has the potential to cause life threatening arrhythmias, such as Torsade de pointes. The 2014 ACC/AHA/HRS guidelines for the management of patients with atrial fibrillation state that patients need to meet certain criteria to be initiated on dofetilide. Patients who are not initiated on this therapy according to the guideline criteria are likely to be at higher risk of adverse reactions.

METHODS

This is a single center, retrospective chart review of patients who were initiated on dofetilide from July 2016-December 2019. Patients included in the study were initiated on dofetilide as a new antiarrhythmic and monitored inpatient for 3 days. The primary outcome was a composite of incidence of cardiac arrhythmias, cardiac arrest, cardiac death, and cardiac related hospital readmission.

RESULTS

There were 224 patients included in the analysis: 190 patients who were initiated on dofetilide inappropriately and 34 that were initiated appropriately. The primary outcome (composite of cardiac arrhythmia, cardiac arrest, cardiac death, and hospital readmission) was statistically significant with more patients experiencing an outcome in the group initiated inappropriately.

CONCLUSIONS

Patients are placed at a higher risk of adverse reactions when this potentially dangerous antiarrhythmic medication is not used according to the protocol set forth by the guidelines. Practitioners should use caution when prescribing dofetilide. Other antiarrhythmic medications or non-pharmacologic options should be considered due to the incidence of these dangerous adverse reactions.

Supporting nurses' recovery during and following the COVID-19 pandemic

Research suggests that working during traumatic events can lead to deteriorating physical and mental health for nurses, a phenomenon that has been demonstrated during the coronavirus 2019 (COVID-19) pandemic. However, research has also shown that there are evidence-based strategies that can be used to assist nurses in their recovery from such events. Promoting awareness among individual nurses about the effects of COVID-19 enables them to adopt positive coping strategies, both on an individual and organisational level. This article details strategies including formal and informal debriefing, taking regular breaks, and using stress mitigation strategies during shifts. The article also discusses the potential for post-traumatic psychological growth. This acknowledges that while working in a healthcare environment during COVID-19 can be extremely challenging, it also enables nurses to experience personal growth such as the development of emotional intelligence. As nurses adapt to the 'new normal' of working during COVID-19, healthcare organisations should ensure that they provide nurses with the support that enables them to recover effectively.

Caregiver burden of patients with heart failure with a left-ventricular ejection fraction (LVEF) less than or equal to 60%: a cross-sectional survey in the EU

Background and purpose

The majority of patients with heart failure (HF) have difficulties in independently carrying out activities of daily living and hence, require support from caregivers (CGs). This study assessed the quality of life (QoL) of CGs of HF patients with sub-normal LVEF (≤60%).

Methods

A cross-sectional survey of HF patients and their CGs was conducted in France, Germany, Italy, Spain and the UK. Cardiologists and primary care physicians completed patient record forms (PRF) between June and November 2019. Caregivers of the same patients were invited to complete a caregiver self-completion survey, which included the Family Caregiver QoL Scale (FAMQOL) and EQ-5D. Patient demographics were derived from PRFs.

Results

361 CGs (73.1% female, mean age: 58.8 yrs) and HF patients (39.9% female, mean age: 71.2 yrs) were included. 58.2% of the CGs were spouses, 23.4% a child of the patient. On average, CGs devoted 20 hrs/week in the care of HF patients; this CG time increased from 12 to 26 hrs/week with NYHA class I to III/IV of the HF patient. Further, anxiety/stress was experienced overall by 29/31% of CGs which increased from 27/17% for NYHA I to 40/41% for NYHA III/IV of the HF patient (Table 1).

Conclusions

Caregivers of patients with HF and LVEF ≤60% spend a significant amount of time to provide daily support to HF patients. Patients with progressive disease were older, more polymorbid and had a higher disease duration. These factors likely contributed towards increased caregiver burden of HF patients with increased NYHA class.

Patients with heart failure and a LVEF less than 40% present an overall lower health related quality of life than those with LVEF between 40% and 60%: a multinational real-world survey in EU

Background and purpose

Heart Failure (HF) is associated with symptoms such as dyspnoea and fatigue which can impact patients' health related quality of life (HRQoL). This study aimed to characterize and assess the HRQoL of patients with HF and left-ventricular ejection fraction (LVEF) &lt;40% versus those with ≥40%-60%.

Methods

A cross-sectional study of patients with HF was conducted in France, Germany, Italy, Spain and United Kingdom. Patient record forms (PRFs) were completed by 257 cardiologists and 158 general practitioners (GPs) for consecutively consulting patients. The same patients were invited to provide patient-reported outcomes including self-completion questionnaires, Minnesota Living with Heart Failure Questionnaire (MLHFQ) and EQ-5D-5L VAS.

Results

204 HF patients with LVEF &lt;40% (mean age 67.7 years) and 600 patients with LVEF ≥40–60% (mean age 68.9 years) were included. Proportion of males was significantly higher in the lower LVEF group (73.5% vs. 61.2%, p=0.0017). Overall, the patients with lower LVEF more frequently presented with comorbidities than those with LVEF ≥40–60% (p&lt;0.05, Figure 1). NYHA stage III/IV (35.8%/7.4% vs. 15.3%/0.8%) as well as self-reported HF symptoms were more frequently reported in the lower LVEF group (p&lt;0.05, Figure 1). Similarly, patients with LVEF &lt;40% reported statistically significantly worse HRQoL compared to those with LVEF ≥40–60% (Table 1).

Conclusions

The HRQoL of all HF patients with LVEF ≤60% appears impacted, while those with LVEF &lt;40% had significantly worse HRQoL than those with LVEF ≥40–60%. These differences in HRQoL may not only be related to the LVEF but also to the overall characteristics of these patients. Addressing the HRQoL burden for patients should be a key aspect of HF management strategies for all HF patients.

Cribriform Adenocarcinoma of the Minor Salivary Gland (CAMSG); A Separate and Malignant Entity

Introduction/Objective

Cribriform adenocarcinoma of the minor salivary gland (CAMSG) is a recently described salivary gland neoplasm (SGN) that WHO includes under the polymorphous adenocarcinoma (PAC) subheading. CAMSG is reported to occur mostly in the base of the tongue and lingual tonsils.

Methods

We present a case of CAMSG of buccal mucosa in a 48-year old woman who presented with pain and swelling on the left side of the face that started after tooth extraction. Imaging revealed a large expansile mass (5.8 x 4.3 x 6.1 cm) originating in the left mandibular angle extending into masticator space, maxillary sinus, pterygopalatine fossa, sphenoid, middle cranial fossa, orbit and skull base. Ameloblastoma, primary intraosseous carcinoma, and squamous cell carcinoma were considered. Incisional biopsy revealed a tumor comprised of round to ovoid cells with clear to vesicular nuclei (ground-glass appearance) and occasional mitosis present in irregular solid, cribriform, and microcystic patterns in a hyalinized stroma with the presence of abundant mucin within lobules and stroma.

Results

Differential diagnosis of secretory carcinoma, hyalinizing clear cell carcinoma, and less likely PAC and mucoepidermoid carcinoma were considered, all inconsistent with the imaging findings. The tumor cells were positive for S100 and negative for CD117, ki67, p63, CD117, and TTF-1. Based on a prominent cribriform pattern, vesicular nuclei, and S-100 expression, a diagnosis of cribriform adenocarcinoma of minor salivary gland origin was rendered. The patient subsequently underwent left partial maxillectomy, left partial mandibulectomy, and resection of the skull base and left neck dissection and was staged as pT4bN0, with negative margins and vascular invasion. The patient underwent radiation therapy and at 6- month follow up was alive and healthy. Clinically and histologically CAMSG overlaps with tumors of both salivary and non-salivary gland origin.

Conclusion

Recognition of CAMSG as a distinct entity will help in accurate diagnosis and categorization in the WHO classification of SGNs.

Operationalizing resilient healthcare concepts through a serious video game for clinicians

Resilient healthcare emphasises the importance of adaptive capacity in quality healthcare. This theory has had extensive theoretical development, but comparatively limited translation for clinicians in practice. This study is the first to present resilient healthcare principles in a serious video game. Serious games are an effective tool for engaging users, sharing ideas and eliciting reflections. The aim of this study was to communicate principles from resilient healthcare to clinicians through a serious video game, and to evaluate the game's feasibility as a prompt to reflect on practice. The game, Resilience Challenge, is scenario-based and requires players to resolve dilemmas in clinical practice. It was disseminated online, and was played 1949 times during the four-month study. The game was evaluated using an immediate cross-sectional survey, which included both Likert-style and free text responses. Participants reported that the game was engaging (93%) and that they would recommend it to others (89%). Fewer participants reported learning about resilient healthcare concepts (64%). Resilience Challenge is a promising way to prompt reflections about clinical work, and demonstrates mixed outcomes in communicating resilient healthcare principles to clinicians.

The changing face of reoperative parathyroidectomy: a single-centre comparison of 147 parathyroid reoperations

INTRODUCTION

Reoperative parathyroidectomy for persistent and recurrent primary hyperparathyroidism is dependent on radiology. This study aimed to compare outcomes in reoperative parathyroidectomy at a single centre using a combination of traditional and newer imaging studies.

MATERIALS AND METHODS

Retrospective case note review of all reoperative parathyroidectomies for persistent and recurrent primary hyperparathyroidism over five years (June 2014 to June 2019; group A). Imaging modalities used and their positive predictive value, complications and cure rates were compared with a published dataset spanning the preceding nine years (group B).

RESULTS

From over 2000 parathyroidectomies, 147 were reoperations (101 in group A and 46 in group B). Age and sex ratios were similar (56 vs 62 years; 77% vs 72% female). Ultrasound use remains high and shows better positive predictive value (76% vs 57 %). 99mTc-sestamibi use has declined (79% vs 91%) but the positive predictive value has improved (74% vs 53%). 4DCT use has almost doubled (61% vs 37%) with better positive predictive value (88% vs 75%). 18F-fluorocholine positron emission tomography-computed tomography and ultrasound-guided fine-needle aspiration for parathyroid hormone are novel modalities only available for group A. Both carried a positive predictive value of 100%. Venous sampling with or without angiography use has decreased (35% vs 39%) but maintains a high positive predictive value (86% vs 91%). Cure rates were similar (96% vs 100%). Group A had 5% permanent hypoparathyroidism, 1% permanent vocal cord palsy and 1% haematoma requiring reoperation. No complications for group B.

CONCLUSION

Optimal imaging is key to good cure rates in reoperative parathyroidectomy. High-quality, non-interventional imaging techniques have produced a shift in the preoperative algorithm without compromising outcomes.

Exploring the experiences of having Guillain-Barré Syndrome: A qualitative interview study

Background

Guillain‐Barré syndrome (GBS) is a rare inflammatory disorder affecting the peripheral nerves. Although typically there is full neurological recovery, some people continue to experience residual physical, psychological or social problems longer term. Evidence describing the experiences of people with GBS is limited.

Objective

We aimed to explore the experiences of people with GBS in the UK.

Design

We used qualitative (face‐to‐face and telephone) interviews to explore experiences of people with GBS. Audio‐recorded data were transcribed verbatim and analysed using the Framework Method supported by NVivo 11.

Setting and Participants

We purposively recruited a sample of 16 volunteers with a prior diagnosis of GBS of varying age, sex, ethnicity, location, marital status, time since diagnosis and length of hospital stay to maximize differences in experience. Interviewees were required to have been discharged from hospital, able to give informed consent, able to speak and understand English and currently resident in the United Kingdom.

Results

The key themes arising from the analysis were as follows: the importance of early diagnosis; the experiences of inpatient care; the importance of active support for recovery; the need for communication throughout the course of the illness; the need for greater awareness, knowledge and provision of information by health‐care staff; and path to achieving function.

Conclusion

This is the first qualitative study exploring experiences of people with GBS in the UK through their whole illness journey from onset to recovery. The findings contribute to our understanding of the experiences and support needs of people recovering from GBS.

FRI0397 THE IMPACT OF OSTEOARTHRITIS DISEASE SEVERITY ON HEALTHCARE RESOURCE USE: ANALYSIS OF REAL-WORLD EUROPEAN DATA

Background:

Osteoarthritis (OA) is a chronic joint disease associated with pain and impaired activity. With increasing obesity trends and an ageing population, the prevalence of OA is expected to rise in the future. This represents an increasing societal problem which will lead to an increased burden on healthcare services.

Objectives:

To understand the pattern of healthcare resource utilisation (HCRU) across France, Germany, Italy, Spain and the UK, as OA disease severity increases.

Methods:

Data were drawn from the Adelphi OA Disease Specific Programme (2017-18), a point-in-time study of physicians and their OA patients. OA disease severity was reported by physicians, who categorised patients’ OA severity as mild, moderate or severe. Patients were excluded from the analyses if they suffered from back and neck OA only, and shoulder OA that had not been diagnosed by X-ray. Physicians provided information, on a patient record form, about OA-related visits to healthcare professionals (HCPs), tests/scans conducted, emergency room (ER) visits and surgeries. Statistical comparisons among disease severity groups were made by analysis of variance and chi-squared tests.

Results:

The study included 489 physicians (primary care physicians, rheumatologists, orthopaedists) reporting on 3596 of their patients with OA: 24% mild (n=874), 53% moderate (n=1904) and 23% severe (n=818). Over the last 12 months, the mean number of consultations with HCPs increased with disease severity (3.7 mild, 4.2 moderate and 5.7 severe [<0.001]). This pattern was also observed in relation to the mean number of tests/scans conducted in the last 12 months (6.9 mild, 7.9 moderate and 9.3 severe [<0.001]). More than a quarter of severe patients visited the ER in the last 12 months (26% vs. 4% mild; 9% moderate [<0.001]) and visits to hospital increased with disease severity (Table 1). The proportion of patients that have had a surgery due to their OA rose with worsening disease severity (11%, 13% and 27% for mild, moderate and severe, respectively [<0.001]).

Table 1.

Physician-reported healthcare burden by OA disease severity

Conclusion:

This real-world data demonstrated an increase in visits to HCPs, monitoring tests and scans, hospitalisations, ER visits and surgery as OA disease severity worsened.

OP0190 UNDERSTANDING CURRENT PRESCRIPTION DRUG TREATMENT PARADIGMS FOR PATIENTS WITH OSTEOARTHRITIS IN EUROPE

Background:

Joint pain is the most prevalent symptom for sufferers of osteoarthritis (OA). Pharmacological management of OA is restricted by limited efficacy and considerable toxicity, with growing fears about opioid use.

Objectives:

To understand the current real-world prescribed drug treatment paradigm related to OA disease severity for patients in 5 EU countries; France, Germany, Italy, Spain and the UK.

Methods:

Data were drawn from the Adelphi OA Disease Specific Programme (2017-18), a point-in-time study of physicians and their patients. Physicians classified their patients as currently having mild, moderate or severe disease severity, and provided details on currently prescribed OA therapy and physician satisfaction with therapy, rated from very satisfied to very dissatisfied. Patients were excluded from these analyses if they suffered from back and neck OA only, and shoulder OA that had not been diagnosed by X-ray. Comparisons among disease severity groups were made using analysis of variance and chi-squared tests.

Results:

The study included 489 physicians (primary care physicians, rheumatologists, orthopaedists) reporting on 3596 of their OA patients: 24% mild (n=874), 53% moderate (n=1904), and 23% severe (n=818). Overall, 73% patients were prescribed at least one drug for their OA (65% of mild; 76% of moderate; 77% of severe patients [<0.001]). Paracetamol (34%) was the most commonly prescribed OA treatment. NSAIDs (31%) and opioids (27%) were also frequently prescribed treatments, and worsening severity was associated with an increase in opioid use (11% of mild; 26% of moderate, 47% of severe patients [<0.001]), but not NSAID (Table 1). The mean number of prescription medications increased (0.9 for mild; 1.4 for moderate; 1.6 for severe patients [<0.001]) and physician satisfaction with treatment decreased (86% for mild; 70% for moderate; 41% for severe [<0.001]) with worsening OA disease severity.

FRI0396 HOW DOES OSTEOARTHRITIS PAIN IMPACT FUNCTION, MOBILITY AND REQUIREMENT FOR HELP IN DAILY ACTIVITIES IN EUROPEAN PATIENTS?

Background:

Symptomatic osteoarthritis (OA) leads to functional limitations and loss of independence. OA management focuses on pain relief and preserving physical function using non-pharmacologic and pharmacologic therapy. Additionally, patients commonly manage OA pain by avoiding activities that exacerbate their pain. Informal care, i.e. assistance from an unpaid caregiver, plays a major role in the total care provided to patients with chronic diseases like OA.

Objectives:

To evaluate how OA pain severity affects physical functioning and the subsequent need for assistance with mobility and daily activities in 5 EU countries: France, Germany, Italy, Spain and UK.

Methods:

Data were drawn from the Adelphi OA Disease Specific Programme (2017-18), a point-in-time study of physicians and their OA patients. Patients rated their average pain intensity over the last week on a 0-10 scale (0 = no pain; 10 = worst possible pain) and were then categorised into mild (0-3), moderate (4-6) and severe (7-10) pain groups. Patients also provided an assessment of their physical function (0-10 WOMAC scale where higher scores indicated greater functional impairment), impact on mobility, whether caregiver assistance was required, daily activities requiring caregiver assistance and home modifications made due to their OA. Physicians also rated patients’ functioning on a 0 to 10 scale (0 = fully functional; 10 = completely impaired). Comparisons among pain severity groups were made using chi-squared tests and analysis of variance.

Results:

The analysis included 1750 OA patients: 24% mild pain (n=413); 47% moderate pain (n=822); 29% severe pain (n=515). The patients were predominantly women (58%) and had a mean (SD) age of 65.6 (11.5).

Increased pain severity was associated with greater functional impairment scores as reported by patients (WOMAC scores: mild pain=2.1; moderate pain=4.1; severe pain=5.9) and physician-rated functional impairment (mild pain=3.5; moderate pain=4.3; severe pain=5.6). Mobility was impacted for 78% of patients with severe pain (vs. 41% mild; 63% moderate) and the need for a walking aid such as a walking stick or walking frame increased with worsening severity; wheelchair assistance was needed for 7% of severe patients (compared with <1% of mild or moderate patients). Furthermore, 31% of patients with severe pain reported having to modify their home due to their OA (vs. 11% mild; 18% moderate [p<0.001]), typically adapting their bathroom (23%) or fitting a stairlift (6%).

The need for assistance from a caregiver to help with daily activities was associated with an increase in patients’ pain (9% mild; 20% moderate; 42% severe [p<0.001]). For most patients this was an immediate family member, however, the proportion of patients paying for professional care also increased with severity (1% mild; 2% moderate; 7% severe). Taking the patient to work or doctor’s appointments; help with shopping; preparing/cooking meals and help with travelling out of the home were most frequently reported activities needing caregiver assistance.

Conclusion:

In this study of European patients, increased pain severity was associated with greater functional impairment and impact on mobility as expected; however, this study highlights the substantial need for assistance with daily activities as well as modifications to the home. The unseen costs to the patient with moderate to severe OA pain are significant.

Substrate Supporting Disc Method for Confirmed Detection of Total Coliforms and E. coli in all Foods: Collaborative Study

The Coli Complete® substrate supporting disc (SSD) method for simultaneous confirmed total coliform count and Escherichia coli determination in all foods was compared with AOAC most probable number (MPN) methods, 966.23 and 966.24. Twenty-nine laboratories participated in this collaborative study in which 6 food types were analyzed. Four food types, raw ground beef, pork sausage, raw liquid milk, and nut meats, were naturally contaminated with coliform bacteria. Two foods, dry egg and fresh frozen vegetables, were seeded with coliforms. Three food types, ground beef, raw liquid milk, and pork sausage, were naturally contaminated with E. coli. Although pork sausage was naturally contaminated, the level was very low (&lt;10/50 g); therefore, additional E. coli were inoculated into 1 lot of this food type. Three food types, nut meats, dry egg, and fresh frozen vegetables, were inoculated with E. coli. For naturally contaminated samples, duplicate determinations were made on 3 separate lots for each food type. For inoculated samples, low, medium, and high contamination levels plus uninoculated control samples were examined in duplicate. Data were analyzed separately for total coliform bacteria and for E. coli. Mean log MPN counts were determined by the SSD method and the appropriate AOAC MPN method. Results were then analyzed for repeatability, reproducibility, and mean log MPN statistical equivalence. Results were statistically equivalent for all total coliform levels in all food types except frozen vegetable and raw nut meat uninoculated control samples and 1 lot of pork sausage where the SSD method produced statistically significant greater numbers. For the E. coli determinations, results were statistically equivalent across all samples and all levels for each food type. The SSD method has been adopted first action by AOAC International for confirmed detection of total coliforms and E. coli in all foods.

Enumeration of Total Aerobic Microorganisms in Foods by SimPlate® Total Plate Count–Color Indicator Methods and Conventional Culture Methods: Collaborative Study

The relative efficacy of the SimPlate® Total Plate Count–Color Indicator (TPC–CI) method (SimPlate 35°C) was compared with the AOAC Official Method 966.23 (AOAC 35°C) for enumeration of total aerobic microorganisms in foods. The SimPlate TPC–CI method, incubated at 30°C (SimPlate 30°C), was also compared with the International Organization for Standardization (ISO) 4833 method (ISO 30°C). Six food types were analyzed: ground black pepper, flour, nut meats, frozen hamburger patties, frozen fruits, and fresh vegetables. All foods tested were naturally contaminated. Nineteen laboratories throughout North America and Europe participated in the study. Three method comparisons were conducted. In general, there was &lt;0.3 mean log count difference in recovery among the SimPlate methods and their corresponding reference methods. Mean log counts between the 2 reference methods were also very similar. Repeatability (sr) and reproducibility (sR) standard deviations were similar among the 3 method comparisons. The SimPlate method (35°C) and the AOAC method were comparable for enumerating total aerobic microorganisms in foods. Similarly, the SimPlate method (30°C) was comparable to the ISO method when samples were prepared and incubated according to the ISO method.

Is social support associated with patient-reported outcomes after joint replacement? A systematic review and meta-analysis

BACKGROUND

Identifying prognostic factors for outcomes after joint replacement could improve the provision of stratified care. This systematic review evaluated whether social support is a prognostic factor for better patient-reported outcomes after total hip replacement (THR) and total knee replacement (TKR).

METHODS

MEDLINE, Embase and PsycINFO were searched from inception to April 2019. Cohort studies evaluating the association between social support and patient-reported outcomes at three months or longer after THR or TKR were included. Data were extracted from study reports. Study quality was assessed using the QUIPS tool. Data were synthesized using meta-analysis and narrative synthesis. The review was registered on PROSPERO (CRD42016041485).

FINDINGS

Searches identified 5,810 articles and 56 studies with data from 119,165 patients were included. In meta-analysis, the presence of social support had a beneficial effect on long-term post-operative WOMAC (mean difference 2.88; 95% CIs 1.30; 4.46) and Oxford Knee Score (0.29; 0.12, 0.45). Social support measured using a validated questionnaire was found to be associated with WOMAC pain (0.04; 0.00, 0.08) but not WOMAC function (-0.01; -0.12, 0.11). The presence of social support had a positive association with some SF-36 subscales but not others. For all outcomes, results of narrative synthesis were inconsistent.

INTERPRETATION

There is evidence that social support is a prognostic factor for some outcomes after joint replacement. Development and evaluation of complex interventions to improve social support and social integration is warranted.
