The Many Challenges of Pension Accounting

ACCOUNTING PERSPECTIVES, Issue 2 2009
Thomas H. Beechy
ABSTRACT Accounting for defined benefit pension plans has long been a major issue in accounting. Standard-setters are grappling with revisions to pension accounting standards, and much change has already occurred in the United Kingdom. This paper identifies and discusses most of the major issues that standard-setters must confront in developing new approaches to financial reporting for pensions. Key issues concern how to report the impact of changes in assumptions, how to recognize pension costs on the balance sheet and income statement, and how to reconcile the differences between accountants' and actuaries' approaches to pensions. Current standards assume that accounting estimates are independent of actuarial assumptions, and yet require a direct comparison of the accounting liability with the pension plan assets, when in fact they are incompatible measures based on differing assumptions and differing methodologies. As well, accounting has been complicit in managers' wishes to hide the volatility inherent in a pension plan investment strategy that focuses on higher-risk equities to fund estimated monetary liabilities that have been discounted at low-risk interest rates. Drawing on studies and research done largely in Europe, this paper attempts to consolidate some of the current thinking on the topic and to propose some preferred approaches to dealing with the problems of pension accounting.

A primary care provider's guide to preventive and acute care management of adults and children with sickle cell disease

JOURNAL OF THE AMERICAN ACADEMY OF NURSE PRACTITIONERS, Issue 5 2009
Ardie Pack-Mabien RNC, CRNP (Clinical Nurse Practitioner & Nurse Manager)
Abstract Purpose: To familiarize primary care providers (PCPs) with the pathophysiological processes, diagnostic evaluation, and medical management of sickle hemoglobinopathies and their complications. Current standards of care, clinical research advances, and new treatment options will also be addressed to assist PCPs in the management of sickle cell disease (SCD). Data sources: A selective search and review of the current literature on SCD and the authors' experience. Conclusions: Management of individuals with SCD is very complex, requiring a multidisciplinary approach that includes the patient or parent, PCP, specialist, nurse, and social worker. More patients living with SCD are relying on PCPs in nonspecialty practices for comprehensive disease management. Implications for practice: Newborn screening detects new cases of SCD annually. The median life expectancy has more than doubled for individuals with sickle cell anemia. Healthcare providers are now in an era of increased routine screening, assessment, and management of chronic complications from this illness not previously seen in the care of adults with SCD.

CPA assessment , the regional assessors' experience

CYTOPATHOLOGY, Issue 2007
G. Guthrie
With the introduction in January 2006 of the new posts of Regional Assessors, the process and focus of CPA assessment changed to reflect the inclusion in the current standards of Quality Management systems and processes. Regional Assessors, trained in Quality Management Systems and their assessment against international standards, now form a vital part of the CPA assessment teams, looking specifically at this aspect of laboratory service provision. Their role in the new assessment process will be explained. The presentation will cover differences and similarities in the nature and number of non-compliances experienced since April 2006 when the new format of assessment was introduced. It will also look at a new format of timetable for assessment visits and explain the benefits of good two-way communication between all parties involved in the process - the laboratory, the assessors, particularly the Regional Assessor assigned to that site, and CPA Office staff. Understanding what is required by the standards, particularly in terms of evidential material, their interpretation and their classification of status , Critical, Non-Critical or Observation - is an aspect of assessment which is often not well understood. The presentation will seek to clarify these issues. The successful and timely clearance by laboratories of any non-compliances raised during the visits is vital to the achievement of accredited status and the presentation will give guidance as to how this is best achieved. The current standards, based on the international ISO 15189 standards, are considerably more challenging than the old ones. There is now a significant emphasis on Quality Management and its understanding, ethos and implementation within the laboratory, a key element which underpins all aspects of a laboratory's service. The achievement of accredited status assures our users of,the type of client and patient focused service expected of a modern laboratory. [source]


An evidence-based approach to equine parasite control: It ain't the 60s anymore

EQUINE VETERINARY EDUCATION, Issue 6 2010
R. M. Kaplan
Summary Most veterinarians continue to recommend anthelmintic treatment programmes for horses that derive from knowledge and concepts more than 40 years old. However, much has changed since these recommendations were first introduced and current approaches routinely fail to provide optimal or even adequate levels of parasite control. There are many reasons for this. Recent studies demonstrate that anthelmintic resistance in equine parasites is highly prevalent and multiple-drug resistance is common in some countries, but few veterinarians take this into account when making treatment decisions or when recommending rotation of anthelmintics. Furthermore, the current approach of treating all horses at frequent intervals was designed specifically to control the highly pathogenic large strongyle, Strongylus vulgaris. But this parasite is now quite uncommon in managed horses in most of the world. Presently, the cyathostomins (small strongyles) are the principal parasitic pathogens of mature horses. The biology and pathogenesis of cyathostomins and S. vulgaris are very different and therefore require an entirely different approach. Furthermore, it is known that parasites are highly over-dispersed in hosts, such that a small percentage of hosts harbour most of the parasites. The common practices of recommending the same treatment programme for all horses despite great differences in parasite burdens, recommending prophylactic treatment of all horses without indication of parasitic disease or knowing what species of parasites are infecting the horses, recommending use of drugs without knowledge of their efficacy and failing to perform diagnostic (faecal egg count) surveillance for estimating parasite burdens and determining treatment efficacy, are all incompatible with current standards of veterinary practice. Consequently, it is necessary that attitudes and approaches to parasite control in horses undergo a complete overhaul. This is best achieved by following an evidence-based approach that takes into account all of these issues and is based on science, not tradition. [source]


Observer variation in immunohistochemical analysis of protein expression, time for a change?

HISTOPATHOLOGY, Issue 7 2006
T Kirkegaard
Aim :,Immunohistochemical analysis of protein expression is central to most clinical translational studies and defines patient treatment or selection criteria for novel drugs. Interobserver variation is rarely analysed despite recognition that this is a key area of potential inaccuracy. Therefore our aim was to examine observer variation and suggest the revision of current standards. Methods and results :,We analysed inter- and intra-observer variation, by interclass correlation coefficient (ICCC) and , statistics, in 8661 samples. Intra-observer assessment of nuclear, cytoplasmic and membrane staining for seven proteins in 1323 samples resulted in an ICCC of 0.94 and a , -value of 0.787. Interobserver reproducibility, assessed on 28 proteins by seven observer pairs in 8661 carcinomas, gave an ICCC of 0.90 and a , -value of 0.70. No significant effect of either antibody or cellular compartmentalization was observed. Conclusion :,We have demonstrated that ICCC is a consistent method to assess observer variation when a continuous scoring system is used, compared with , statistics, which depends on a categorical system. Given the importance of accurate assessment of protein expression in diagnostic and experimental medicine, we suggest raising thresholds for observer variation: ICCC of 0.7 should be regarded as the minimum acceptable standard, ICCC of 0.8 as good and ICCC of ,,0.9 as excellent.

Attitudes towards skills examinations for basic surgical trainees

INTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 1 2005
S.D. Bann
Summary Objective measures of surgical skill and cognition are becoming available. A questionnaire study examining surgeons' beliefs towards a skills-based examination, current standards and possible benefits was devised. Three hundred pairs of standardised anonymous questionnaires were sent to consultants and their basic surgical trainees (BSTs) irrespective of surgical speciality. Responses were requested using a Likert scale (1,5, 3 = neutral response). Two-hundred and two replies were received (including 54 pairs). BST experience ranged from 6 to 60 months (mean 24 months). When questioned regarding current training in basic surgical skills, only 34% believed that they were given adequate training at present. Sixty-four per cent of respondents believed the introduction of a skills examination would raise standards and 66% believed it necessary. Eighty-three per cent of respondents believed that they or their BST would practice these skills, if an examination were introduced and 85% wanted or would provide dedicated teaching time for this. However, 68% had no access to a dedicated skills facility, and uptake of these, where available, was variable. When questioned about their ability to perform the six appropriate tasks, there was a poor correlation of scoring between the groups. Consultants and their BSTs do not believe that they are given adequate training in basic skills. The introduction of an examination would lead to practice of these skills and is seen as a positive move. [source]


Effectiveness of a Multidisciplinary Quality Improvement Initiative in Reducing Door-to-Balloon Times in Primary Angioplasty

JOURNAL OF INTERVENTIONAL CARDIOLOGY, Issue 4 2004
F.A.C.C., STUART W. ZARICH M.D.
Primary angioplasty (PA) for acute myocardial infarction (AMI) has emerged as the standard of care in hospitals with cardiac interventional facilities. The benefits from the PA are time dependent, but recent data raise concerns regarding the timeliness of delivery of care in AMI and the level of benefit achieved by current standards. We assessed the effectiveness of an extensive multidisciplinary quality improvement initiative in reducing door-to-balloon (DTB) times in PA. The PA process was divided into six separate time periods, which were assessed individually. Subsequent quality initiatives resulted in a dramatic reduction in the mean DTB time (141.3 minutes preintervention compared to 95.1 minutes postintervention; P < 0.001). [source]


Latest news and product developments

PRESCRIBER, Issue 5 2007
Article first published online: 16 MAY 200
OFT wants PPRS reform The Office of Fair Trading (www.oft.gov.uk) says reform of the Pharmaceutical Price Regulatory Scheme (PPRS) would allow the NHS to re- invest 500 million in drugs it needs. Its investigation of the 50- year-old PPRS concludes that the scheme does not reflect the therapeutic value of drugs and, while providing a financial safety net for the industry, it mitigates against innovation. The OFT believes drugs should be priced according to their therapeutic value based on their cost effectiveness. Analyses would be fast- tracked for new drugs or, if there are insufficient data, a risk-sharing scheme should be adopted. The ABPI insists that its medicines offer the NHS value for money and believes the OFT's proposal for drug- by-drug pricing would delay access to new medicines. Switching saves money and is problem free Switching to cheaper alternatives within a drug class does not affect the quality of care and offers substantial savings, say UK researchers (Int J Clin Pract 2007;61:15-23). They switched selected patients from atorvastatin (Lipitor) to simvastatin and from losartan (Cozaar) to candesartan (Amias). Exclusion criteria included previous unsuccessful use, poor control of lipids or blood pressure, contraindications and potential drug interactions. In 70 patients switched to simvastatin, there was no change in mean total cholesterol after four months; one patient reverted to atorvastatin due to adverse effects. Of 115 switched to candesartan, seven reverted to losartan; in the remainder, blood pressure was slightly reduced after four months. The switch was not associated with adverse effects. Savings for the year 2005/06 were estimated at 12 716 for statins and 13 374 for antihypertensive drugs. Scotland gets donepezil for mild to moderate AD The Scottish Medicines Consortium (www.scottish medicines.org.uk) has approved the use of orodispersible donepezil (Aricept Evess) for the treatment of mild to moderate Alzheimer's disease in NHS Scotland. The decision conflicts with NICE advice that the drug is not appropriate for patients with mild disease. The SMC has not approved rimonabant (Acomplia) as adjunctive treatment for obese patients. Adherence threatens anticoagulation Patients find it difficult to adhere to anticoagulant treatment ,significantly impairing the quality of anticoagulation, US investigators have shown (Arch Intern Med 2007;167:229-35). Using electronic containers to monitor dose adherence over 32 weeks in 136 patients, they found that 92 per cent opened the container at least once too often or too little and one-third missed 20 per cent of scheduled openings. Patients with less than 20 per cent adherence were twice as likely to be undercoagulated compared with adherent patients. Those with overadherence were overcoagulated. Hypo risk greatest with glibenclamide Glibenclamide is associated with a significantly greater risk of hypoglycaemic events than other secretagogues, a new systematic review has concluded (Diabetes Care 2007;30:389-94). The review of 21 randomised trials found that the risk of experiencing at least one hypoglycaemic event was 52 per cent greater with glibenclamide compared with other secretagogues and 83 per cent greater than with other sulphonylureas. In three comparative trials with insulin, there was no significant difference in the risk of hypoglycaemia (though this could not be excluded) but only insulin was associated with weight gain. Glibenclamide was not associated with significantly increased risks of cardiovascular events, weight gain or death. Few major hypoglycaemic events were reported in these trials. Drug groups implicated in ADR admissions Four classes of drugs account for half of hospital admissions for adverse reactions, according to a new systematic review (Br J Clin Pharmacol 2007;63:136-47). Antiplatelet agents (16 per cent of admissions), diuretics (16 per cent), NSAIDs (11 per cent) and anticoagulants (8 per cent) were implicated in drug- related admissions according to a review of nine studies. Analysis of five studies also showed that adherence problems were associated with one-third of drug-related admissions. The authors suggest that focussing resources in these areas could substantially reduce admissions. Value of pharmacist MUR questioned Pharmacist medicines use review (MUR) for older patients does not reduce hospital readmission and is not cost effective by current standards, according to a study from Norfolk (Pharmacoeconomics 2007;25:171-80). A total of 872 patients aged over 80 who had been admitted as an emergency and discharged taking two or more drugs were randomised to MUR by a pharmacist or usual care. The pharmacist visited twice, providing education, removing out-of-date drugs and checking for adverse effects, interactions and the need for compliance aids. After six months, the admissions rate was not reduced among patients who received MUR and quality of life was not significantly improved. The estimated cost per QALY gained was 54 454 , above the conventional threshold for cost effectiveness of 30 000. MHRA review of LABAs The MHRA has clarified which aspects of long-acting beta-agonists (LABAs) are being addressed in its current review. This full review of salmeterol (Serevent) and formoterol, following advice issued in December last year, will consider recent research, whether the two agents differ significantly, dose-response relationships, the effect of concurrent treatment with inhaled steroid and how they are used in practice. Manufacturers have been asked to provide data by the end of March. Interventions for weight gain in schizophrenia There is not enough evidence to support the use of drugs to reduce weight gain associated with schizophrenia, a new Cochrane review has found (Cochrane Database of Systematic Reviews 2007, Issue 1. Art. No.: CD005148. DOI: 10.1002/14651858. CD005148.pub2). Noting a lack of adequate trials, the review found that cognitive/behavioural interventions effectively prevented weight gain by a mean of 3.4kg and reduced established weight gain by a mean of 1.7kg. Drugs prevented weight gain by about 1.2kg. Switching anti-TNFs An analysis of a UK rheumatoid arthritis (RA) registry has shown that patients who stop treatment with their first anti-TNF agent should be switched to a second (Arthr Rheum 2007;56:13-20). Every UK patient with RA who receives an anti-TNF agent is included in the British Society for Rheumatology Biologics Register. Analysis of this database identified 6739 patients who started treatment, of whom 841 stopped within 15 months due to lack of efficacy and 1023 due to toxicity. Of these, 503 and 353 respectively were switched to another anti- TNF agent. Overall, 73 per cent of patients remained on their second drug by the end of follow-up, but patients were two to three times more likely to stop their second treatment for the same reason they discontinued their first.

Research institute for nurse scientists responds to the challenge to expand and strengthen research focused on breast cancer in African American women,

CANCER, Issue S2 2007
Sandra Millon Underwood RN
Abstract In an era where scientifically derived ,evidence' is used as a basis for nursing practice, it is imperative that nurses have a breadth of knowledge relative to the fundamentals of nursing science; knowledge of the current standards of nursing and medical practice; and knowledge of the characteristics, needs, concerns, and challenges of diverse consumer and patient population groups. Yet, while a significant body of ,evidence' that describes the experiences and needs of African American women across the breast care continuum has been generated, research suggests that there is a need to expand and strengthen this body of science. This report presents an overview of a decade of research focused on breast cancer among African American women and describes an initiative funded by the Susan G. Komen Breast Cancer Foundation to expand and strengthen nursing science that aims to reduce and/or eliminate excess breast cancer morbidity and mortality among African American women.

Day procedure intervention is safe and complication free in higher risk patients undergoing transradial angioplasty and stenting.

CATHETERIZATION AND CARDIOVASCULAR INTERVENTIONS, Issue 7 2007
The discharge study
Abstract Objectives: To assess the timeframe of postprocedural complications following transradial percutaneous intervention in selected nonlow-risk risk patients as a feasibility study for same day discharge. Background: Percutaneous coronary intervention (PCI) is traditionally performed as an inpatient procedure. Transradial access with its lower complication rate facilitates safe and same day discharge. We hypothesize that with current standards of pharmacotherapy and intervention, complications post transradial percutaneous coronary angioplasty even in a nonlow-risk patient cohort will be evident within 6 hr or occur more than 24 hr post procedure. Under these circumstances, overnight stay results in no improvement in patient safety. Methods: 2,189 patients underwent transradial PCI at our institution between January 2005 and June 2006. Of these 1,174 were assessed as intermediate or high risk and admitted postprocedure. The remaining 1,015 were assessed as low risk and discharged the day of procedure. All 1,174 inpatients were entered into our study database. Information was collected on patient demographics, angiographic characteristics, post procedural complications, and timing of post procedural events. Results: 1,543 ACC type B2 or C lesions were treated in 1,174 patients. All post-procedural complications were identified within 6 hr of the intervention or occurred more than 24 hr later when patients would have been discharged according to overnight admission protocols. Conclusions: Day case transradial percutaneous intervention with a 6-hr period of post procedure observation is a safe and feasible practice. The presence of higher-risk features should not be considered an absolute indication for overnight admission in patients considered clinically appropriate for discharge. 2007 Wiley-Liss, Inc.

Fine-needle aspiration biopsy and other biopsies in suspected intraocular malignant disease: a review

ACTA OPHTHALMOLOGICA, Issue 6 2009
Nils Eide
Abstract. Ocular oncologists require a strong indication for intraocular biopsy before the procedure can be performed because it carries a risk for serious eye complications and the dissemination of malignant cells. The purpose of this review is to evaluate the extent to which this restricted practice is supported by evidence from previous reports and to outline our main indications and contraindications. The different intraocular biopsy techniques in the anterior and posterior segment are discussed with a focus on our preferred method, fine-needle aspiration biopsy (FNAB). In the literature, complications are typically under-reported, which reduces the possibilities of evaluating the risks correctly and of making fair comparisons with other biopsy methods. In FNAB, the exact placement of the needle is critical, as is an accurate assessment of the size of the lesion. Fine-needle aspiration biopsy is usually not a reliable diagnostic tool in lesions < 2 mm in thickness. It is very advantageous to have a cytopathologist present in the operating theatre or close by. This ensures adequate sampling and encourages repeated biopsy attempts if necessary. This approach reduces false negative results to < 3%. Adjunct immunocytochemistry is documented to increase specificity and is essential for diagnosis and management in about 10% of cases. In some rare pathological processes the diagnosis depends ultimately on the identification of specific cell markers. An accurate diagnosis may have a decisive influence on prognosis. The cytogenetic prognostications made possible after FNAB are reliable. Biopsy by FNA has a low complication rate. The calculated risk for retinal detachment is < 4%. Intraocular haemorrhage is frequently observed, but clears spontaneously in nearly all cases. Only a single case of epibulbar seeding of malignant cells at the scleral pars plana puncture site of transvitreal FNAB has been documented. Endophthalmitis has been reported and adequate standard preoperative preparation is obligatory. An open biopsy is still an option in the anterior segment, but has been abandoned in the posterior segment. Although vitrectomy-based procedures are becoming increasingly popular, we recommend using FNAB as part of a stepwise approach. A vitrectomy-assisted biopsy should be considered in cases where FNAB fails. In any adult patient with suspected intraocular malignancy in which enucleation is not the obvious treatment, the clinician should strive for a diagnosis based on biopsy. When the lesion is too small for biopsy or the risks related to the procedure are too great, it is reasonable to be reluctant to biopsy. The standards applied in the treatment of intraocular malignant diseases should be equivalent to those in other fields of oncology. Our view is controversial and contrary to opinion that supports current standards of care for this group of patients. [source]
