Association between pacifier use and breast-feeding, sudden infant death syndrome, infection and dental malocclusion

INTERNATIONAL JOURNAL OF EVIDENCE BASED HEALTHCARE, Issue 6 2005
Ann Callaghan RN RM BNurs(Hons)
Executive summary Objective, To critically review all literature related to pacifier use for full-term healthy infants and young children. The specific review questions addressed are: What is the evidence of adverse and/or positive outcomes of pacifier use in infancy and childhood in relation to each of the following subtopics: ,breast-feeding; ,sudden infant death syndrome; ,infection; ,dental malocclusion. Inclusion criteria, Specific criteria were used to determine which studies would be included in the review: (i) the types of participants; (ii) the types of research design; and (iii) the types of outcome measures. To be included a study has to meet all criteria. Types of participants,The participants included in the review were healthy term infants and healthy children up to the age of 16 years. Studies that focused on preterm infants, and infants and young children with serious illness or congenital malformations were excluded. However, some total population studies did include these children. Types of research design, It became evident early in the review process that very few randomised controlled trials had been conducted. A decision was made to include observational epidemiological designs, specifically prospective cohort studies and, in the case of sudden infant death syndrome research, case,control studies. Purely descriptive and cross-sectional studies were excluded, as were qualitative studies and all other forms of evidence. A number of criteria have been proposed to establish causation in the scientific and medical literature. These key criteria were applied in the review process and are described as follows: (i) consistency and unbiasedness of findings; (ii) strength of association; (iii) temporal sequence; (iv) dose,response relationship; (v) specificity; (vi) coherence with biological background and previous knowledge; (vii) biological plausibility; and (viii) experimental evidence. Studies that did not meet the requirement of appropriate temporal sequencing of events and studies that did not present an estimate of the strength of association were not included in the final review. Types of outcome measures,Our specific interest was pacifier use related to: ,breast-feeding; ,sudden infant death syndrome; ,infection; ,dental malocclusion. Studies that examined pacifier use related to procedural pain relief were excluded. Studies that examined the relationship between pacifier use and gastro-oesophageal reflux were also excluded as this information has been recently presented as a systematic review. Search strategy, The review comprised published and unpublished research literature. The search was restricted to reports published in English, Spanish and German. The time period covered research published from January 1960 to October 2003. A protocol developed by New Zealand Health Technology Assessment was used to guide the search process. The search comprised bibliographic databases, citation searching, other evidence-based and guidelines sites, government documents, books and reports, professional websites, national associations, hand search, contacting national/international experts and general internet searching. Assessment of quality, All studies identified during the database search were assessed for relevance to the review based on the information provided in the title, abstract and descriptor/MeSH terms, and a full report was retrieved for all studies that met the inclusion criteria. Studies identified from reference list searches were assessed for relevance based on the study title. Keywords included: dummy, dummies, pacifier(s), soother(s), comforter(s), non-nutritive sucking, infant, child, infant care. Initially, studies were reviewed for inclusion by pairs of principal investigators. Authorship of articles was not concealed from the reviewers. Next, the methodological quality of included articles was assessed independently by groups of three or more principal investigators and clinicians using a checklist. All 20 studies that were accepted met minimum set criteria, but few passed without some methodological concern. Data extraction, To meet the requirements of the Joanna Briggs Institute, reasons for acceptance and non-acceptance at each phase were clearly documented. An assessment protocol and report form was developed for each of the three phases of review. The first form was created to record investigators' evaluations of studies included in the initial review. Those studies that failed to meet strict inclusion criteria were excluded at this point. A second form was designed to facilitate an in-depth critique of epidemiological study methodology. The checklist was pilot tested and adjustments were made before reviewers were trained in its use. When reviewers could not agree on an assessment, it was passed to additional reviewers and discussed until a consensus was reached. At this stage, studies other than cohort, case,control and randomised controlled trials were excluded. Issues of clarification were also addressed at this point. The final phase was that of integration. This phase, undertaken by the principal investigators, was assisted by the production of data extraction tables. Through a process of trial and error, a framework was formulated that adequately summarised the key elements of the studies. This information was tabulated under the following headings: authors/setting, design, exposure/outcome, confounders controlled, analysis and main findings. Results, With regard to the breast-feeding outcome, 10 studies met the inclusion criteria, comprising two randomised controlled trials and eight cohort studies. The research was conducted between 1995 and 2003 in a wide variety of settings involving research participants from diverse socioeconomic and cultural backgrounds. Information regarding exposure and outcome status, and potential confounding factors was obtained from: antenatal and postnatal records; interviews before discharge from obstetric/midwifery care; post-discharge interviews; and post-discharge postal and telephone surveys. Both the level of contact and the frequency of contact with the informant, the child's mother, differed widely. Pacifier use was defined and measured inconsistently, possibly because few studies were initiated expressly to investigate its relationship with breast-feeding. Completeness of follow-up was addressed, but missing data were not uniformly identified and explained. When comparisons were made between participants and non-participants there was some evidence of differential loss and a bias towards families in higher socioeconomic groups. Multivariate analysis was undertaken in the majority of studies, with some including a large number of sociodemographic, obstetric and infant covariates and others including just maternal age and education. As might be expected given the inconsistency of definition and measurement, the relationship between pacifier use and breast-feeding was expressed in many different ways and a meta-analysis was not appropriate. In summary, only one study did not report a negative association between pacifier use and breast-feeding duration or exclusivity. Results indicate an increase in risk for a reduced overall duration of breast-feeding from 20% to almost threefold. The data suggest that very infrequent use may not have any overall negative impact on breast-feeding outcomes. Six sudden infant death syndrome case,control studies met the criteria for inclusion. The research was conducted with information gathered between 1984 and 1999 in Norway, UK, New Zealand, the Netherlands and USA. Exposure information was obtained from a variety of sources including: hospital and antenatal records, death scene investigation, and interview and questionnaire. Information for cases was sought within 2 days after death, within 2,4 weeks after death and in one study between 3 and 11 years after death. Information for controls was sought from as early as 4 days of a nominated sudden infant death syndrome case, to between 1 and 7 weeks from the case date, and again in one study some 3,11 years later. In the majority of the studies case ascertainment was determined by post-mortem. Pacifier use was again defined and measured somewhat inconsistently. All studies controlled for confounding factors by matching and/or using multivariate analysis. Generally, antenatal and postnatal factors, as well as infant care practices, and maternal, family and socioeconomic issues were considered. All five studies reporting multivariate results found significantly fewer sudden infant death syndrome cases used a pacifier compared with controls. That is, pacifier use was associated with a reduced incidence of sudden infant death syndrome. These results indicate that the risk of sudden infant death syndrome for infants who did not use a pacifier in the last or reference sleep was at least twice, and possibly five times, that of infants who did use a pacifier. Three studies reported a moderately sized positive association between pacifier use and a variety of infections. Conversely, one study found no positive association between pacifier use at 15 months of age and a range of infections experienced between the ages of 6 and 18 months. Given the limited number of studies available and the variability of results, no meaningful conclusions could be drawn. Five cohort studies and one case,control study focused on the relationship between pacifier use and dental malocclusion. Not one of these studies reported a measure of association, such as an estimate of relative risk. It was therefore not possible to include these studies in the final review. Implications for practice, It is intended that this review be used as the basis of a ,best practice guideline', to make health professionals aware of the research evidence concerning these health and developmental consequences of pacifier use, because parents need clear information on which they can base child care decisions. With regard to the association between pacifier use and infection and dental malocclusion it was found that, due to the paucity of epidemiological studies, no meaningful conclusion can be drawn. There is clearly a need for more epidemiological research with regard to these two outcomes. The evidence for a relationship between pacifier use and sudden infant death syndrome is consistent, while the exact mechanism of the effect is not well understood. As to breast-feeding, research evidence shows that pacifier use in infancy is associated with a shorter duration and non-exclusivity. It is plausible that pacifier use causes babies to breast-feed less, but a causal relationship has not been irrefutably proven. Because breast-feeding confers an important advantage on all children and the incidence of sudden infant death syndrome is very low, it is recommended that health professionals generally advise parents against pacifier use, while taking into account individual circumstances.

Effect of hospitalist attending physicians on trainee educational experiences: A systematic review,

JOURNAL OF HOSPITAL MEDICINE, Issue 8 2009
Pradeep Natarajan MD
Abstract BACKGROUND: Trainees receive much of their inpatient education from hospitalists. PURPOSE: To characterize the effects of hospitalists on trainee education. DATA SOURCES: MEDLINE, Database of Reviews of Effectiveness (DARE), National Health Service (NHS) Economic Evaluation Database (EED), Health Technology Assessment (HTA), and the Cochrane Collaboration Database (last searched October 2008) databases using the term "hospitalist", and meeting abstracts from the Society of Hospital Medicine (SHM) (2002-2007), Society of General Internal Medicine (SGIM) (2001-2007), and Pediatric Academic Societies (PAS) (2000-2007). STUDY SELECTION: Original English language research studies meeting all of the following: involvement of hospitalists; comparison to nonhospitalist attendings; evaluation of trainee knowledge, skills, or attitudes. 711 articles were reviewed, 32 retrieved, and 6 included; 7,062 meeting abstracts were reviewed, 9 retrieved, and 2 included. DATA EXTRACTION: Two authors reviewed articles to determine study eligibility. Three authors independently reviewed included articles to abstract data elements and classify study quality. DATA SYNTHESIS: Seven studies were quasirandomized one was a noncontemporaneous comparison. All citations only measured trainee attitudes. In all studies comparing hospitalists to nonhospitalists, trainees were more satisfied with hospitalists overall, and with other aspects of their teaching, but ratings were high for both groups. One of 2 studies that distinguished nonhospitalist general internists from specialists showed that trainees preferred hospitalists, but the other did not demonstrate a hospitalist advantage over general internists. CONCLUSIONS: Trainees are more satisfied with inpatient education from hospitalists. Whether the increased satisfaction translates to improved learning is unclear.

The Socioeconomic Impact of Atopic Dermatitis in the United States: A Systematic Review

PEDIATRIC DERMATOLOGY, Issue 1 2008
Anthony J. Mancini M.D.
A search was performed using OVID MEDLINE, MEDLINE In-Process and Other Non-Indexed Citations, EMBASE, the International Agency for Health Technology Assessment (INAHTA) database, and the Cochrane Library. All abstracts were reviewed for the following criteria: original cost data, studies performed in the United States, and English language. The search yielded 418 papers. Fifty-nine papers were reviewed in detail, and four studies were found that met the inclusion criteria. These cost-identification analyses estimated the cost of atopic dermatitis heterogeneously and could not be compared directly. National cost estimates ranged widely, from $364 million to $3.8 billion US dollars per year. The cost of atopic dermatitis is significant and will likely increase in proportion to increasing disease prevalence. Measurement of the cost of atopic dermatitis in the United States has been limited to direct cost-identification analyses, with few studies measuring the indirect cost of disease. [source]

Glitazones more than double fracture risk An analysis of the UK General Practice Research Database has found that both glitazones increase the risk of fracture more than two-fold (Arch Intern Med 2008;168:820-5). Compared with nonusers, the odds ratio for fracture (mostly hip and wrist) was 2.59 for pioglitazone and 2.38 for rosiglitazone. The risk increased with dose but was unrelated to age and sex. Reduce antipsychotics in dementia patients Antipsychotics should be prescribed for patients with dementia only as a last resort at times of severe distress or critical need, the All-Party Parliamentary Group on Dementia has concluded. Its inquiry (available at www.alzheimers.org.uk) found that antipsychotics are being prescribed for patients with mild behavioural symptoms and for prolonged periods despite the limited benefits they offer and the risk of serious adverse effects such as stroke. Contributory factors include lack of training for staff, inadequate leadership and exclusion of family and friends from decisions about treatment. High-dose atorvastatin in chronic kidney disease High-dose atorvastatin (Lipitor) reduces cardiovascular events in patients with chronic kidney disease (CKD) more than a low dose , despite similar reductions in LDL-C (J Am Coll Cardiol 2008;51:1448-54). A post hoc subgroup analysis of the Treating-to-New-Targets study involving 10 001 patients with CHD, with or without CKD, found that atorvastatin 10 and 80mg per day reduced LDLC and triglycerides to similar levels; there was no change in HDL-C. After a median follow-up of five years, the incidence of cardiovascular events in patients with CKD was 9.3 per cent at 80mg per day and 13.4 per cent at 10mg per day (number needed to treat to prevent one event, NNT, 24). In patients with no CKD, the corresponding figures were 7.9 vs 9.2 per cent (NNT 74). There was no difference in all-cause mortality; adverse events were more frequent at the higher dose. COX-2 NSAIDs not more cost-effective An economic analysis of COX-2 selective NSAIDs has concluded that they are not more cost effective than older agents plus a proton pump inhibitor (PPI) in the treatment of osteoarthritis and rheumatoid arthritis (Health Technology Assessment 2008;12:No. 11). The analysis concluded that selective and nonselective NSAIDs were similarly effective but selective agents were associated with a lower risk of upper GI events and a higher risk of cardiovascular events. However, the available evidence includes only low numbers of events and further studies are needed. Compared with ibuprofen or diclofenac plus a PPI, the COX-2 selective NSAIDs look ,generally unattractive from a cost effectiveness point of view', even in high-risk patients with a history of peptic ulcer. There were insufficient data to allow a reliable comparison within the COX-2s. Naftidrofuryl helps intermittent claudication Naftidrofuryl increases pain-free walking distance (PFWD) in patients with intermittent claudication, a new Cochrane review has shown (Cochrane Database of Systematic Reviews 2008, Issue 2. Art. No.: CD001368. DOI: 10.1002/ 14651858.CD001368.pub3; also see page 49 in this issue). The meta-analysis of six trials involving a total of 1083 patients found that, compared with placebo, naftidrofuryl increased PFWD by over a third with a proportion successfully treated of 20 per cent (NNT 4.5). Coversyl Arginine To clarify any confusion following our recent news item (Perindopril brand switch, 19 April issue, page 12), Servier has asked us to reiterate that the new formulations Coversyl Arginine 2.5, 5 and 10mg are equivalent to 2, 4 and 8mg of the discontinued Coversyl formulation. Coversyl Arginine contains perindopril arginine, a salt that offers greater stability and a longer shelf-life. Prescriptions for the Coversyl brand of perindopril must in future be written as Coversyl Arginine in its revised strengths. Coversyl Plus has also been replaced by Coversyl Arginine Plus and the same revised dosages apply. Generic formulations of perindopril remain unaffected.

GPs and pharmacists to work more closely Closer working between GPs and community and primary-care pharmacists ,could further improve prescribing quality and therapeutic outcomes for patients', according to a report by the London School of Pharmacy and Alliance Boots. The report suggests that the expansion of primary-care centres and the increasing complexity of care they offer mean that community pharmacists will increasingly need to take on some GP roles. It foresees an increase in shared premises and calls for closer interdisciplinary working between GPs, pharmacists and nurses. Variation in PCT commissioning of enhanced services from pharmacies has resulted in ,a fragmented system of postcode pharmaceutical care rationing'. Full read-write access to patients' records will be essential if the benefits of electronic prescribing are to be realised. How pharmacists can support commissioners The NHS Alliance and Primary Care Pharmacists' Association have published a guide for practice-based commissioners on making the most of primary-care pharmacists. Prescribing Support and Prescribing Advice for Practice Based Commissioners , A Guide for Commissioning Groups and GPs illustrates how pharmacists can support commissioners at all levels of medicines use. Copies are free to NHS Alliance members and cost £10 for others. Directory website aids diabetes management The National Diabetes Support Team is developing a website that brings together different datasets and tools for diabetes management. The Diabetes Data Directory (www.yhpho.org.uk/diabetesdatadirectory/introddd.asp) summarises what other online databases can provide and lists the tools that can be used to answer specific questions. The first edition is now online, providing direct links to the appropriate sites. Flu vaccine efficacy in older people challenged US reviewers have questioned the effectiveness of flu vaccine in older people (Lancet Infect Dis online: 24 September; doi: 10.1016/ S1473-3099(07)70236-0). They were unable to confirm a reduction in flu mortality since 1980, concluding that biased patient selection and nonspecific end-points such as all-cause mortality may have exaggerated the benefits of vaccination in clinical trials. The Department of Health is encouraging younger people in at-risk groups to be vaccinated against flu this winter; last year, 58 per cent of under-65s at risk were not vaccinated. OC cervical cancer risk probably overestimated Recent evidence that oral contraceptives may be associated with a small increase in the incidence of cervical cancer probably overestimates the risk, says the Clinical Effectiveness Unit of the Faculty of Family Planning and Reproductive Health Care (www.ffprhc.org.uk). A recent study in the BMJ reported a 12 per cent reduced overall risk of cancer associated with oral contraceptives but an increased risk of cervical cancer of 38 per 100 000 woman-years after at least eight years' use. The FFPRHC says this study was conducted before the UK cervical screening programme was established, and at a time when the average Inhaled insulin ,unlikely to be cost effective' Inhaled insulin (Exubera) is safe and effective but costs so much more than injected insulin that it is unlikely to be cost effective, according to a new Health Technology Assessment (2007;11:No.33.www.hta.nhsweb.nhs.uk). The review included nine trials (seven of Exubera), in which the only significant difference between inhaled and injected soluble insulin was in patient preference. However, most of the trials used syringes for insulin injection rather than pens. The extra cost of inhaled insulin is put at between £600 and £1000 per year. New topics for NICE The Secretary of State for Health has referred the novel antihypertensive aliskiren (Rasilez) for appraisal by NICE; aliskiren is the first direct renin inhibitor to be introduced. Other referrals to NICE include five clinical guidelines (multiple pregnancy, transient loss of consciousness, lower UTI in men, post-ITU rehabilitation and colorectal and anal cancer). Topics for technology appraisals include cetuximab (Erbitux) for colorectal and head and neck cancers. QOF statistics for 06/07 GPs in England averaged 96.3 per cent of the maximum points available for the clinical domain of the Quality and Outcomes Framework in 2006/07 compared with 97.1 per cent previously, official statistics show. Mean practice scores for most clinical areas were in the mid-90 per cent range, but highest for obesity (100 per cent) and lowest for depression (81 per cent), palliative care (90 per cent), mental health and epilepsy (<95 per cent). NICE consulting on type 2 diabetes guideline NICE is consulting on its draft clinical guideline for the management of type 2 diabetes. Comments should be submitted online by 22 November; publication is scheduled for April 2008. The drug of first choice for glycaemic control is metformin, which should be considered even for patients who are not overweight; a sulphonylurea is an alternative or adjunctive agent if glycaemic control is not achieved with metformin alone. If these regimens fail, a glitazone may be added. Exenatide (Byetta) is recommended only for obese patients for whom other oral treatments have failed. The guidance will update and replace clinical guidelines E, F, G and H, and technology appraisals 53, 60 and 63. Glitazones increase risk of HF but not CV death A new meta-analysis , this time of seven trials involving a total of 20 191 patients with type 2 diabetes or impaired glucose tolerance treated with a glitazone , has concluded that these agents are associated with an increased risk of heart failure but not cardiovascular death (Lancet 2007;370:1129,36). Compared with comparator drugs, glitazones were associated with an increased risk of congestive heart failure (2.3 vs 1.4 per cent; relative risk, RR, 1.72; number needed to harm over 30 months, 107). There was no heterogeneity between studies, showing that this is a class effect. However, the risk of cardiovascular death was not increased for either rosiglitazone (Avandia) or pioglitazone (Actos). Copyright © 2007 Wiley Interface Ltd [source]


One of These Things Is Not Like the Others: The Idea of Precedence in Health Technology Assessment and Coverage Decisions

THE MILBANK QUARTERLY, Issue 2 2005
MITA GIACOMINI
Health plans often deliberate covering technologies with challenging purposes, effects, or costs. They must integrate quantitative evidence (e.g., how well a technology works) with qualitative, normative assessments (e.g., whether it works well enough for a worthwhile purpose). Arguments from analogy and precedent help integrate these criteria and establish standards for their policy application. Examples of arguments are described for three technologies (ICSI, genetic tests, and Viagra). Drawing lessons from law, ethics, philosophy, and the social sciences, a framework is developed for case-based evaluation of new technologies. The decision-making cycle includes (1) taking stock of past decisions and formulating precedents, (2) deciding new cases, and (3) assimilating decisions into the case history and evaluation framework. Each stage requires distinctive decision maker roles, information, and methods. [source]


Economic analysis for clinical practice , the case of 31 national consensus guidelines in the Netherlands

JOURNAL OF EVALUATION IN CLINICAL PRACTICE, Issue 1 2007
Louis W. Niessen MD
Abstract Rationale, aims and objective, Evidence on the cost-effectiveness of health interventions in the development of practice guidelines has become of interest in many countries. Challenges are the quality of economic data, the use of cost-effectiveness criteria, and the consensus process. Our paper aims to assess the quality and use of economic information in the formulation of consensus guidelines in a Dutch pilot programme and to recommend improvements. Methods, ,Retrospective qualitative review of economic evaluations and formulated recommendations, using a checklist based on international standards. Results, The national programme to support the development of guidelines with economic analysis in multidisciplinary consensus groups run from 1998 to 2002. It has included 31 medical guidelines, addressing 23 conditions across seven International Classification of Diseases (ICD)-disease groups. Experts in health technology assessment have participated in the guidelines groups. Economic information in all guidelines varies by all criteria in the level of evidence used. Information on quality-adjusted life years gained is limited as is statistical analysis in most studies. Highest cost-effectiveness ratios reported are between ,20 000 and ,30 000. However, there is no uniformity in the definitions of acceptable cost-effectiveness ratios. Conclusions, Economic recommendations can be included in guidelines. Interaction between clinicians and health economists promotes a balance between medical and economic arguments. Among panellists there appears to be agreement on the level of the cost-effectiveness ratios that is acceptable. It is recommended that economic analysis is used to strengthen the evidence-base of guidelines. An evidence-grading system should include the quality of economic evaluation. Roles of policymakers and providers need to be defined. [source]


RAPID VERSUS FULL SYSTEMATIC REVIEWS: VALIDITY IN CLINICAL PRACTICE?

ANZ JOURNAL OF SURGERY, Issue 11 2008
Amber Watt
Introduction: Rapid reviews are being produced with greater frequency by health technology assessment (HTA) agencies in response to increased pressure from end-user clinicians and policy-makers for rapid, evidence-based advice on health-care technologies. This comparative study examines the differences in methodologies and essential conclusions between rapid and full reviews on the same topic, with the aim of determining the validity of rapid reviews in the clinical context and making recommendations for their future application. Methods: Rapid reviews were located by Internet searching of international HTA agency websites, with any ambiguities resolved by further communication with the agencies. Comparator full systematic reviews were identified using the University of York Centre for Reviews and Dissemination HTA database. Data on a number of review components were extracted using standardized data extraction tables, then analysed and reported narratively. Results: Axiomatic differences between all the rapid and full reviews were identified; however, the essential conclusions of the rapid and full reviews did not differ extensively across the topics. For each of the four topics examined, it was clear that the scope of the rapid reviews was substantially narrower than that of full reviews. The methodology underpinning the rapid reviews was often inadequately described. Conclusions: Rapid reviews do not adhere to any single validated methodology. They frequently provide adequate advice on which to base clinical and policy decisions; however, their scope is limited, which may compromise their appropriateness for evaluating technologies in certain circumstances.

Visually directed high-intensity focused ultrasound for organ-confined prostate cancer: a proposed standard for the conduct of therapy

BJU INTERNATIONAL, Issue 6 2006
Rowland O. Illing
OBJECTIVE To propose a standard for the conduct of visually directed transrectal high-intensity focused ultrasound (HIFU) and to offer a formal description of the changes observed on B-mode ultrasonography (US) during this procedure. We describe our early experience of using two different treatment methods; algorithm-based HIFU and visually directed HIFU for the treatment of organ-confined prostate cancer. PATIENTS AND METHODS Between November 2004 and October 2005, 34 men were treated using the Sonablate®-500 (Focus Surgery, Indianapolis, IN, USA) as primary therapy for T1 or T2 prostate cancer. None had had previous hormone therapy and all had ,,3-month PSA nadirs recorded at the follow-up. Nine men were treated using an algorithm-based protocol (group 1) and 25 using visually directed therapy (group 2). The conduct of visually directed treatment was described and changes seen using B-mode US were categorized using three ,Uchida' grades. RESULTS The mean PSA nadir achieved in group 2 was 0.15 ng/mL, vs 1.51 ng/mL in group 1 (P < 0.005). In group 2, 21 of 25 men achieved PSA nadirs of ,,0.2 ng/mL 3 months after treatment. Seven men achieved undetectable PSA values. The occurrence rate of treatment-related toxicity was similar in both groups. CONCLUSION Visually directed, transrectal HIFU enables clinically important and statistically significantly lower PSA nadirs to be achieved than algorithm-based HIFU. This is the first reported experience of visually directed HIFU for the treatment of organ-confined prostate cancer. We think that this is the first attempt to standardize the conduct of therapy; such standardization facilitates teaching it, and makes it possible to derive quality standards. The standardization of the conduct of therapy is a key step in the process of health technology assessment. [source]


ASERNIP-S: INTERNATIONAL TREND SETTING

ANZ JOURNAL OF SURGERY, Issue 10 2008
Guy Maddern
The Australian Safety and Efficacy Register of New Interventional Procedures , Surgical (ASERNIP-S) came into being 10 years ago to provide health technology assessments specifically tailored towards new surgical techniques and technologies. It was and remains the only organisation in the world to focus on this area of research. Most funding has been provided by the Australian Government Department of Health, and assessments have helped inform the introduction of new surgical techniques into Australia. ASERNIP-S is a project of the Royal Australasian College of Surgeons. The ASERNIP-S program employs a diverse range of methods including systematic reviews, technology overviews, assessments of new and emerging surgical technologies identified by horizon scanning, and audit. Support and guidance for the program is provided by Fellows of the Royal Australasian College of Surgeons. ASERNIP-S works closely with consumers to produce health technology assessments and audits, as well as consumer information to keep patients fully informed of research. Since its inception, the ASERNIP-S program has developed a strong international profile through the production of over 60 reports on evidence-based surgery, surgical technologies and audit. The work undertaken by ASERNIP-S has evolved from assessments of the safety and efficacy of procedures to include guidance on policies and surgical training programs. ASERNIP-S needs to secure funding so that it can continue to play an integral role in the improvement of quality of care both in Australia and internationally. [source]
