Toward a Continuous Quality Improvement Paradigm for Hemodialysis Providers with Preliminary Suggestions for Clinical Practice Monitoring and Measurement

HEMODIALYSIS INTERNATIONAL, Issue 1 2003
Edmund G. Lowrie
Background: Consensus processes using the clinical literature as the primary source for information generally drive projects to draft clinical practice guidelines (CPGs). Most such literature citations describe special projects that are not part of an organized quality management initiative, and the publication/review/consensus process tends to be long. This project describes an initiative to develop and explore a flexible and dedicated data-driven paradigm for deciding new CPGs that could be rapidly responsive to changing medical knowledge and practice. Methods: Candidate Clinical Practice Monitoring Measures (CPMM) were selected using a large, national database according to the natures and strengths of their associations with mortality risk among patients during 1994. Thresholds above or below which risk of death increased were evaluated for each CPMM using risk profile charts and spline functions. The fractions of patients outside of those thresholds in each dialysis unit (the %Var) were determined for the years 1993, 1994, and 1995. A standardized mortality ratio (SMR) was also determined for each year for each facility. The associations between the %Var and SMR were evaluated in several single-variable and multivariable statistical models. Results: Eleven CPMM were selected and evaluated based on their associations with death risk. These included the urea clearance x dialysis time product (Kt); the concentrations of albumin, potassium, phosphate, bicarbonate, hemoglobin, neutrophils, and lymphocytes in the blood; the body weight/height ratio; diastolic blood pressure; and vascular access type. Even though the CPMM were strongly associated with death risk among patients, the %Var were weakly and inconsistently associated with SMR among facilities. Conclusions: The paradigm was flexible, easy to implement, quickly executed, and potentially able to accommodate evolving medical practice assuming the availability of large database systems such as this. The primary associates of death risk were easily identified and the thresholds easily adopted. The SMR and %Var from the CPMM were only weakly associated, however, suggesting that one cannot be reliably predicted from the other. As such, quality management programs should likely monitor both the processes and outcomes of care among dialysis facilities. [source]


Radiographic periodontal attachment loss as an indicator of death risk in the elderly

JOURNAL OF CLINICAL PERIODONTOLOGY, Issue 2 2000

Abstract Objectives: Oral infections have been associated with serious systemic diseases and an increased risk of death. Our aims were to investigate whether radiographically-observed apical periodontitis lesions, carious teeth, periodontal attachment loss (horizontal bone loss, furcation lesions, number of teeth with infrabony periodontal pockets, the extent of infrabony periodontal pockets) and the sum of all these findings have any relationships with all-cause mortality within 4-year follow-up. Material and methods: 292 community-dwelling elderly persons aged 76, 81 and 86 years. The number of deaths within 4 years was 54 (18.5%). In the dentate 169 subjects, of whom 32 (18.9%) deceased within 4 years, the mean number of teeth was 15.5 in men and 13.2 in women. The imaging method used was panoramic radiography supplemented by intraoral radiographs. Results: 51% of the dentate subjects had infrabony pockets (mean 1.5, s.d. 2.2), and 40% had periapical periodontitis lesions (mean 1.0, s.d. 1.6). After controlling for age and gender, vertical bone loss judged as advanced infrabony pockets was associated with 4-year all-cause mortality (Odds ratio 2.2,1.0,4.7). Other associations were statistically insignificant. Conclusion: Periodontal attachment loss may indicate an increased risk of death in the elderly. [source]

PRESCRIBER, Issue 12 2007

NAO: GPs still not prescribing efficiently The National Audit Office (NAO) says NHS funds are being wasted through inefficient GP prescribing and patients not taking their medicines. The NAO's long-awaited report, Prescribing Costs in Primary Care (www.nao.org.uk), found large variations between PCTs in generic prescribing of statins, ACE inhibitors and angiotensin-II antagonists, and protonpump inhibitors; PCTs were also paying widely differing prices for these products. There was a five-fold variation in prescribing volume for clopidogrel between PCTs. These four drugs accounted for only 19 per cent of total spending but, if all practices matched the performance of the best 25 per cent, the NHS would save £200 million annually. PCTs should do more to rationalise prescribing and support their GPs, the NAO concludes. The NAO says that the cost of medicines dispensed for but not taken by patients lies somewhere in the range £100-£800 million annually. Strategies to reduce waste include public awareness campaigns and restricting supplies to four weeks (or two weeks for new medicines). Rosiglitazone may increase CV death risk A meta-analysis of 42 clinical trials has suggested that rosiglitazone is associated with increased risks of myocardial infarction (MI) and cardiovascular death (N Engl J Med 2007; published online 21 May: doi 10.1056/ NEJMoa072761). Like the COX-2 inhibitors, rosiglitazone was licensed without determining its possible effects on long-term cardiovascular outcomes, and interpretation of the latest findings is complicated by the multiple comparisons involved. For risk of MI, there was no significant difference between rosiglitazone and placebo (though this was of borderline statistical signifi-cance , p=0.07), metformin, sulphonylureas or insulin. Rosiglitazone was associated with a statistically significant 43 per cent increased risk compared with all comparators combined but the absolute increase in risk was very small (0.02 per cent). The trends were similar for risk of cardiovascular death, though rosiglitazone was associated with a 64 per cent increased risk compared with all comparators combined that was of borderline statistical significance (p=0.06). The authors acknowledge that their analysis pooled short-term studies that excluded patients at risk of heart disease and was not designed to determine cardiovascular outcomes, and they had no access to patientlevel data; as a result, there is uncertainty about their findings. Nevertheless, they say there is now an urgent need to clarify the risk associated with rosiglitazone. GlaxoSmithKline has rebutted the findings, stating that the cardiovascular risk profile of rosiglitazone is comparable with that of other oral antidiabetic drugs. The MHRA says warnings in the current SPCs for Avandia and Avandamet already reflect most of the data in the latest US review. The possible effects of rosiglitazone on cardiovascular events is currently being evaluated in the Rosiglitazone Evaluated for Cardiac Outcomes and Regulation of glycaemia in Diabetes (RECORD) study. Good management tool The Department of Health has published a disease management tool to enable PCTs to model local interventions that could reduce emergency admissions. The web-based ,voluntary good practice tool' will demonstrate how interventions in primary care and social care settings can improve the management of long-term conditions including cardiovascular disease, asthma and COPD, and dementia and depression. Counterfeit medicines The MHRA has issued an unprecedented three alerts about fake medicines in the legitimate supply chain, recalling all affected lot numbers. Three batches of Zyprexa 10mg tablets (olanzapine) were withdrawn after a company printing labels became suspicious and alerted Eli Lilly. Two of the batches, which contained 60 per cent of the stated active ingredient, had reached patients but no adverse events were reported. Two lots of parallel-imported Plavix 75mg tablets (clopidogrel) have been withdrawn after counterfeit packs were identified. The lots were in French original packaging but will have been overlabelled for the UK market. The counterfeits were mixed with genuine packs from Sanofi-Aventis. Fake Casodex 50mg tablets (bicalutamide) have been identified in a parallel import from France. The Royal Pharmaceutical Society reports that the fake contains 75 per cent of the stated dose of bicalutamide. Alcohol-free mometasone Schering-plough has introduced an alcohol-free formulation of mometasone furoate nasal spray (Nasonex) for hay fever. The company says that an alcohol vehicle causes nasal irritation and leaves an unpleasant aftertaste, adding that over 40 per cent of patients cite this as the main reason for stopping treatment, and over 50 per cent state a preference for an alcohol-free product. Aid to improve statin adherence Adherence to statin therapy can be improved if patients use a decision aid when they are offered treatment,US investigators say (Arch Intern Med 2007;167:1076-82). The decision aid estimated the individual's 10-year cardiovascular risk and the risk reduction from treatment, and summarised the disadvantages of statins.Patients with diabetes who used the aid knew more about their risk and were less indecisive about treatment than those who did not. The odds of having missed a dose over three months were three times higher for patients who had not used the aid. Online tool calculates switch savings A new online tool can help GPs estimate the savings achievable from switching patients to cheaper medicines. The Switch Saving Calculator, developed by the Prescribing Analysis & Support Team at the NHS Regional Drug and Therapeutics Centre in Newcastle, calculates potential savings based on past, current or projected use of the target drug. It can be applied to individual prescribers or scaled up to practice, commissioning group, PCT, health authority or even national level. Separate calculators are available for primary and secondary care. The current version calculates potential savings by switching from atorvastatin to simvastatin. The Newcastle team says other drugs will be added and they will update prices regularly. The calculator is at www.nyrdtc.nhs.uk:80/Services/presc_supp/ switch_saving_calculator/switch_saving_calculator.html. No improvement in drug information for patients leaving hospital The information given to patients discharged from hospital is not improving, according to the Healthcare Commission's annual patient survey (www.healthcare commission.org.uk). The 2006 survey found that the commonest reason patients were kept waiting for at least four hours to leave hospital was the delay in providing discharge medicines. Provision of written information increased from 62 per cent of patients in 2005 to 65 per cent in 2006. However, only 76 per cent said they had been told about their medicines in a way they could ,completely' understand (79 per cent in 2002). The proportion of patients reporting complete information about sideeffects also fell (from 40 per cent in 2005 to 37 per cent). Aspirin in preeclampsia A new meta-analysis has found that primary prevention with low-dose aspirin modestly but consistently reduces the risk of preeclampsia (Lancet 2007; published online 18 May). The study of 31 trials involving 32 217 women at low to moderate risk found that antiplatelet agents (mostly aspirin) reduced the risk of pre-eclampsia and preterm birth by 10 per cent without an increased risk of bleeding. The benefit was similar across subgroups. There were also nonsignificant reductions in the risk of small for age, stillborn and death before discharge. New from NICE NICE approves varenicline for NHS NICE has endorsed the use of varenicline (Champix) as an aid to smoking cessation within the NHS for England and Wales; it has already been approved for use in Scotland by the Scottish Medicines Consortium. Varenicline is a partial agonist at the ,4,2 nicotinic receptor. It alleviates craving and withdrawal symptoms, and reduces the rewarding and reinforcing effects of smoking. The commonest adverse effect is mild to moderate nausea, which improves with time.1 Varenicline is licensed for smoking cessation in adults; NICE says it should be offered as an option for smokers who say they want to quit as part of a programme of behavioural support. However, treatment should not be withheld if counselling and support are not available. NICE was critical of manufacturer Pfizer's economic arguments in favour of varenicline, which inappropriately included US data, assumed a single quit attempt and may have overestimated its efficacy. It nonetheless concluded that varenicline is more effective than nicotine replacement therapy (NRT) or bupropion (Zyban) in achieving continuous abstinence. NICE estimated that, compared with NRT, the odds of abstinence at one year with varenicline were 54 per cent greater. A Cochrane review1 concluded that abstinence was 66 per cent more likely with varenicline than with bupropion, and three times more likely than with placebo. There was also a benefit from offering smokers a wider choice of treatments. A 12-week course of varenicline costs £163.80; it is also licensed for an additional 12-week course and dose tapering may be considered for those at high risk of relapse. The final appraisal determination does not state which is the treatment of first choice for smoking cessation. NICE is currently preparing guidance on smoking cessation in pri-mary care, pharmacies and workplaces. Copyright © 2007 Wiley Interface Ltd [source]


Incidence, management and mortality of acute hypoxemic respiratory failure and acute respiratory distress syndrome from a prospective study of Chinese paediatric intensive care network

ACTA PAEDIATRICA, Issue 5 2010
X Hu
Abstract Aim:, To investigate the incidence, clinical management, mortality and its risk factors, major outcome and costs of acute hypoxemic respiratory failure (AHRF) and acute respiratory distress syndrome (ARDS) in a Chinese network of 26 paediatric intensive care unit (PICU). Methods: In a consecutive 12-month period, AHRF and ARDS were identified and followed up for 90 days or until death or discharge. Results:, From a total of 11 521 critically ill patients, 461 AHRF were identified in which 306 developed ARDS (66.4%), resulting in incidences of 4% and 2.7%, respectively, with pneumonia (75.1%) and sepsis (14.7%) as main underlying diseases and 83% were 5 years and 1 month-old. In-hospital mortality of AHRF was 41.6% (44.8% for ARDS), accounted for 15.5% of all PICU deaths. For those of pneumonia or sepsis with AHRF and ARDS, mortality and its relative risk were significantly higher than those without. Relatively lower tidal volume and total fluid balance, adequate upper limit of PaCO2 in the early PICU days, and family affordability, tended to result in better outcome. Conclusion:, In this prospective study, AHRF had high possibilities to develop ARDS and death risk, as impacted by ventilation settings and fluid intake in the early treatment, as well as socioeconomic factors, which should be considered for implementation of standard of care in respiratory therapy.

Increased death risk and altered cancer incidence pattern in patients with isolated or combined autoimmune primary adrenocortical insufficiency

CLINICAL ENDOCRINOLOGY, Issue 5 2008
Sophie Bensing
Summary Objectives, Primary adrenocortical insufficiency is mostly caused by an autoimmune destruction of the adrenal cortex. The disease may appear isolated or as a part of an autoimmune polyendocrine syndrome (APS). APS1 is a rare hereditary disorder with a broad spectrum of clinical manifestations. In APS2, primary adrenocortical insufficiency is often combined with autoimmune thyroid disease and/or type 1 diabetes. We analysed mortality and cancer incidence in primary adrenocortical insufficiency patients during 40 years. Data were compared with the general Swedish population. Design and patients, A population based cohort study including all patients with autoimmune primary adrenocortical insufficiency (3299) admitted to Swedish hospitals 1964,2004. Measurements, Mortality risk was calculated as the standardized mortality ratio (SMR) and cancer incidence as the standardized incidence ratio (SIR). Results, A more than 2-fold increased mortality risk was observed in both women (SMR 2·9, 95% CI 2·7,3·0) and men (SMR 2·5, 95% CI 2·3,2·7). Highest risks were observed in patients diagnosed in childhood. SMR was higher in APS1 patients (SMR 4·6, 95% CI 3·5,6·0) compared with patients with APS2 (SMR 2·1, 95% CI 1·9,2·4). Cancer incidence was increased (SIR 1·3, 95% CI 1·2,1·5). When tumours observed during the first year of follow-up were excluded, only the cancer risk among APS1 patients remained increased. Cause-specific cancer incidence analysis revealed significantly higher incidences of oral cancer, nonmelanoma skin cancer, and male genital system cancer among patients. Breast cancer incidence was lower than in the general population. Conclusions, Our study shows a reduced life expectancy and altered cancer incidence pattern in patients with autoimmune primary adrenocortical insufficiency. [source]
