In this questionnaire we asked about: (1) the nature of services currently offered to families with hearing impaired children, (2) what recurrence risks they quoted in isolated non-syndromic cases, and (3) what they might suggest for improving the range of genetic services available at present. We noted great variation both in these services and in the recurrence risks quoted in isolated cases. Based on the results of the questionnaire, we have proposed a protocol for the investigation of permanent childhood hearing impairment, which we believe to be both comprehensive and practical in an outpatient clinic setting. It is only by improving existing clinical and social understanding and knowledge of childhood hearing impairment that it will become possible to use recent molecular advances to develop comprehensive and consistent services for these families.  (+info)

Should a history section be included on the National Youth Sports Program preparticipation physical examination? (2/1125)

The National Youth Sports Program (NYSP) is an annual event sponsored by the National Collegiate Athletic Association that provides structured sports and enrichment programs to youth of low socioeconomic status. As part of the program, youths undergo a free medical examination that uses a physical examination checklist but does not include a section on medical history. To determine what additional information a medical history would provide, a history form was used in conjunction with the regular preparticipation examination for participants in the 1996 NYSP at the North Carolina Agricultural and Technical State University. The history form provided information such as family history of sudden death, personal history of asthma or bone injury, and whether participants took medications or used corrective lenses. Seventy-nine percent of the completed history forms documented a positive response to at least one question. Of these, only 5% had physical findings on examination. Conversely, 15% of participants had physical findings that were not reported on the history form. Because much of what is discovered by a medical history often is not found on physical examination and because history information can be used to prevent the occurrence of an accident or illness, this study suggests that the use of such a form is beneficial in providing a more comprehensive screening.  (+info)

Use of laboratory testing for genital chlamydial infection in Norway. (3/1125)

OBJECTIVE: To assess the use of laboratory tests for genital chlamydial infection in Norway. DESIGN: Questionnaire survey of general practitioners' practice in chlamydial testing, retrospective survey of laboratory records, 1986-91, and prospective study of testing in one laboratory during four weeks. SETTING: All 18 microbiological laboratories in Norway (4.2 million population), including one serving all doctors in Vestfold county (0.2 million population). SUBJECTS: 302 general practitioners. MAIN MEASURES: GPs' routine practice, methods used for testing, 1986-91, and sex specific and age group specific testing in 1991. RESULTS: 201(69%) GPs replied to the questionnaire: 101(51%) would test all women younger than 25 years at routine pelvic examination, 107(54%) all girls at first pelvic examination, 131(66%) all pregnant women, and 106(54%) all men whose female partner had urogenital complaints. Nationwide in 1986, 122,000 tests were performed (2.9 per 100 population); 10% were positive and 51% were cell culture tests. In 1991, 341,000 tests were performed (8.0 per 100 population); 4.5% were positive and 15% were cell culture tests. 13,184 tests were performed in Vestfold in 1991 (6.6 per 100 population). The age group specific rates (per 100 population) among women were: age 15-19 years, 22.0(95% confidence interval 18.2 to 25.8); 20-24 years, 47.2(42.1 to 52.3); 25-29 years, 42.3(37.1 to 47.5); 30-34 years, 29.8(25.4 to 34.2); and 35-39 years, 12.5(9.5 to 15.5). CONCLUSIONS: GPs use liberal indications for testing. The dramatic increase in testing, especially by enzyme immunoassays, in populations with a low prevalence of infection results in low cost effectiveness and low predictive value of positive tests, which in women over 29 years is estimated as 17-36%. IMPLICATIONS: Doctors should be educated about the limitations of enzyme immunoassays in screening low prevalence populations, and laboratories should apply a confirmatory test to specimens testing positive with such assays.  (+info)

Description of local adaptation of national guidelines and of active feedback for rationalising preoperative screening in patients at low risk from anaesthetics in a French university hospital. (4/1125)

OBJECTIVE: To describe the effect of local adaptation of national guidelines combined with active feedback and organisational analysis on the ordering of preoperative investigations for patients at low risk from anaesthetics. DESIGN: Assessment of preoperative tests ordered over one month, before and after local adaptation of guidelines and feedback of results, combined with an organisational analysis. SETTING: Motivated anaesthetists in 15 surgical wards of Bordeaux University Hospital, Region Aquitain, France. SUBJECTS: 42 anaesthetists, 60 surgeons, and their teams. MAIN OUTCOME MEASURES: Number and type of preoperative tests ordered in June 1993 and 1994, and the estimated savings. RESULTS: Of 536 patients at low risk from anaesthetics studied in 1993 before the intervention 80% had at least one preoperative test. Most (70%) tests were ordered by anaesthetists. Twice the number of preoperative tests were ordered than recommended by national guidelines. Organisational analysis indicated lack of organised consultations and communication within teams. Changes implemented included scheduling of anaesthetic consultations; regular formal multidisciplinary meetings for all staff; preoperative ordering decision charts. Of 516 low risk patients studied in 1994 after the intervention only 48% had one or more preoperative tests ordered (p < 0.05). Estimated mean (SD) saving for one year if changes were applied to all patients at low risk from anaesthesia in the hospital 3.04 (1.23) mFF. CONCLUSIONS: A sharp decrease in tests ordered in low risk patients was found. The likely cause was the package of changes that included local adaptation of national guidelines, feedback, and organisational change.  (+info)

Using evidence-based techniques to modify anemia screening practice. (5/1125)

Routine screening of adolescents for iron-deficiency anemia is a widespread but unproven practice. Using evidence-based quality improvement techniques, including literature synthesis and presentation of clinic-specific data, my colleagues and I reevaluated a clinic policy of obtaining complete blood counts to screen for anemia in all new adolescent patients. Medical record review revealed clinically unsuspected anemia in 8 (3.5) of 229 patients screened. All cases were mild, and only two patients received iron therapy. These data, coupled with national recommendations, led to a reversal of the clinic's policy requiring screening of all new patients. One year later, complete blood counts were obtained for only 6% of new patients.  (+info)

Cost implications of selective preoperative risk screening in the care of candidates for peripheral vascular operations. (6/1125)

The preoperative identification that patients are at high risk for adverse postoperative outcomes is the first step toward preventing costly in-hospital complications. The economic implications of noninvasive screening strategies in the care of patients undergoing peripheral vascular operations must be clarified. A decision model was developed from the peer-reviewed literature on patients undergoing preoperative screening by means of dipyridamole myocardial perfusion imaging, dobutamine echocardiography, or cardiac catheterization before vascular operations (n = 23 studies). Routine versus selective screening strategies were compared for patients with an intermediate likelihood of having coronary artery disease on the basis of clinical history of coronary disease or typical symptoms. Median costs (1994 US dollars) of preoperative screening strategies were derived with two microcosting approaches: adjusted Medicare charges (top-down approach) and a bottom-up approach with Duke University Center direct cost estimate data. In-hospital cost was 11% higher for preoperative screening by means of routine cardiac catheterization ($27,760) than for routine pharmacologic stress imaging ($24,826, P = 0.001). The total cost of a do-nothing strategy, that is, no preoperative testing, was 5.9% less than that of routine preoperative pharmacologic stress imaging and 15.9% lower than that of cardiac catheterization (P = 0.001). Selective screening among patients with a history of coronary disease or typical angina resulted in further reduction of the cost of care to a level comparable with that of a do-nothing strategy (52.5% reduction in cost with pharmacologic stress imaging, P > 0.20). Use of noninvasive testing for preoperative risk stratification was cost effective for patients 60 to 80 years of age. Cost per life saved ranged from $33,338 to $21,790. However, coronary revascularization after an abnormal noninvasive test was cost effective only for patients older than 70 years. In this economic decision model, substantial cost savings were predicted when selective noninvasive stress imaging was added to preoperative screening for patients about to undergo vascular operations. With a selective screening approach, the economic impact of initial diagnostic testing may be minimized without compromising patient outcomes.  (+info)

Monitoring patients with diabetes mellitus: an application of the probit model using managed care claims data. (7/1125)

The primary objective of this study was to estimate the likelihood of the use of either a glycosylated hemoglobin (HbA1c) test or an eye examination, or both, among a cohort of patients diagnosed with diabetes mellitus. A secondary objective was to provide a step-by-step discussion of the applicability of an econometric model to managed care organizations. The study used medical and pharmacy claims data from a managed care organization for the calendar year 1995. A probit regression model was specified to estimate the probability of occurrence for either an HbA1c test or an eye examination among patients with insulin-dependent, non-insulin dependent, or atypical/unclassified diabetes. Data were available only for patients under 65 years of age due to data truncation for patients covered by Medicare, resulting in a study sample size of 6,841. Results indicate that age, presence of hypertension, hyperlipidemia, multiple cardiovascular comorbidities, ophthalmic disease, and combinations of multiple commonly observed comorbidities were positively correlated with the probability of either HbA1c testing or eye examination. Gender and the type of benefit plan were not statistically significant as predictors of disease monitoring. A total of 1,860 patients with diabetes mellitus were predicted by the model to have undergone one of the two monitoring procedures; but in actuality, these patients were not monitored in 1995. They could be considered as high-risk patients who were not getting recommended monitoring. The probit model shows a predictive power of 64.48%.  (+info)

The clinical value of commonly used spinal fluid diagnostic studies in the evaluation of patients with suspected multiple sclerosis. (8/1125)

OBJECTIVE: This study was designed to evaluate the diagnostic value of cerebrospinal fluid (CSF) oligoclonal banding and immunoglobulin G (IgG) production in the diagnosis of multiple sclerosis. STUDY DESIGN: Spinal fluid changes in patients with suspected multiple sclerosis were compared with clinical data to determine sensitivity, specificity, and predictive value of the procedures. The results were evaluated in terms of cost compared with clinical utility in the managed care environment. PATIENTS AND METHODS: The CSF oligoclonal banding and CSF IgG index were measured in 50 patients being evaluated for possible multiple sclerosis at a multispecialty group practice clinic. RESULTS: CSF oligoclonal banding had a sensitivity of 75% and a specificity of 92% in the diagnosis of multiple sclerosis. The CSF IgG index had a sensitivity of 75% and a specificity of 95% in the diagnosis of multiple sclerosis. CONCLUSIONS: Although neither test would identify 100% of patients with multiple sclerosis, the combination of CSF oligoclonal banding and an elevated CSF IgG index correctly identified most patients with multiple sclerosis and excluded all patients without the disease in this patient population.  (+info)

Logistic regression is a statistical model widely used in cross-sectional and cohort studies to identify and quantify the effects of potential disease risk factors. However, the impact of imperfect tests on adjusted odds ratios (and thus on the identification of risk factors) is under-appreciated. The purpose of this article is to draw attention to the problem associated with modelling imperfect diagnostic tests, and propose simple Bayesian models to adequately address this issue. A systematic literature review was conducted to determine the proportion of malaria studies that appropriately accounted for false-negatives/false-positives in a logistic regression setting. Inference from the standard logistic regression was also compared with that from three proposed Bayesian models using simulations and malaria data from the western Brazilian Amazon. A systematic literature review suggests that malaria epidemiologists are largely unaware of the problem of using logistic regression to model imperfect
Findings: The proportion of patients with suspected malaria for whom a diagnostic test result for malaria was recorded decreased in arm B (adjusted RR (aRR) = 0.97; 99%CI: 0.82,1.14) during IMID, but increased 25% in arm A (aRR = 1.25; 99%CI:0.94, 1.65) during IMID and OSS relative to baseline; (aRRR = 1.28; 99%CI:0.93, 1.78). The estimated proportion of patients that received an appropriate antimalarial among those prescribed any antimalarial increased in arm B (aRR = 1.09; 99%CI: 0.87, 1.36) and arm A (aRR = 1.50; 99%CI: 1.04, 2.17); (aRRR = 1.38; 99%CI: 0.89, 2.13). The proportion of patients with a negative diagnostic test result for malaria prescribed an antimalarial decreased in arm B (aRR = 0.96; 99%CI: 0.84, 1.10) and arm A (aRR = 0.67; 99%CI: 0.46, 0.97); (aRRR = 0.70; 99%CI: 0.48, 1.00). The proportion of patients with a positive diagnostic test result for malaria prescribed an antibiotic did not change significantly in either arm ...

We developed a tool for assessing risk of bias in the results of non-randomised studies of interventions that addresses weaknesses in previously available approaches.4 Our approach builds on recent developments in risk of bias assessment of randomised trials and diagnostic test accuracy studies.8 9 Key features of ROBINS-I include specification of the target trial and effect of interest, use of signalling questions to inform judgements of risk of bias, and assessments within seven bias domains.. The ROBINS-I tool was developed through consensus among a group that included both methodological experts and systematic review authors and editors, and was substantially revised based on extensive piloting and user feedback. It includes a structured approach to assessment of risk of bias due to confounding that starts at the review protocol stage. Use of ROBINS-I requires that review groups include members with substantial methodological expertise and familiarity with modern epidemiological thinking. We ...

Fourteen studies were identified and included in the analysis. Diagnostic tests results indicated that treatment effects were not constant over time in the PH model, and the AFT model better fit the trial data and, therefore, was used in the analysis. Studies using lower dose intensities of DTIC (800 mg/m2/d) were excluded due to heterogeneity. The inverse acceleration factors for OS and PFS for each treatment, compared with DTIC, are shown in the table (values lower than 1 indicate increased survival). ...

We all have a significant amount of challenges into having balance within our lifestyles. Theres just a ton of demands placed on us. And we really have to address and deal with those demands in a way that allows us to relax during the day. So lifestyle factors and our daily routines play a significant role in the development of chronic pain. Whether its poor pacing, feeling rushed, the lack of breaks, sitting too long throughout the day. These risk factors probably play as much of a role in chronic pain as other factors. For example, women on the average spend about 17 minutes of alone time per day. Well, without time to sit and take a deep breath. To think about your day and youre only reacting.

Doctors treating infectious diseases still dont have rapid diagnostic tests which could help them identify the exact strains of pathogens ailing their patients. The development of such tests is complex and expensive, but that may improve thanks to IMIs RAPP-ID project, which developed some of the technologies and innovations needed to speed up the development of such tests in the future. For example, the project developed a prototype of a breath sampler for influenza - the first test which uses something as simple as breathing out to detect the presence of pathogens in patients. Some of the technologies created under RAPP-ID are undergoing further development in new EU-funded projects.
The diagnostic tests including sensitivity, specificity, PVpos; PVneg, likelihood ratio are explained with examples. ROC-curves are also presented. .

INTRODUCTION: Delirium is a severe neuropsychiatric syndrome of rapid onset, commonly precipitated by acute illness. It is common in older people in the emergency department (ED) and acute hospital, but greatly under-recognised in these and other settings. Delirium and other forms of cognitive impairment, particularly dementia, commonly coexist. There is a need for a rapid delirium screening tool that can be administered by a range of professional-level healthcare staff to patients with sensory or functional impairments in a busy clinical environment, which also incorporates general cognitive assessment. We developed the 4 As Test (4AT) for this purpose. This studys primary objective is to validate the 4AT against a reference standard. Secondary objectives include (1) comparing the 4AT with another widely used test (the Confusion Assessment Method (CAM)); (2) determining if the 4AT is sensitive to general cognitive impairment; (3) assessing if 4AT scores predict outcomes, including (4) a health

All dried blood samples at 2,000 parasites/μl retained reactivity (100% sensitivity) at all three temperatures and time points for all nine RDT brands that detect histidine-rich protein-2 (HRP2). The dried blood samples with 200 parasites/μl were detected by six of the nine HRP2-based RDTs at all storage temperatures and time points. The sensitivity for two of the three remaining HRP2-based RDTs was 100% up to four weeks of storage at all temperatures but dropped to 87.5% at week 12. Of the four RDTs that detect plasmodium lactate dehydrogenase (pLDH) in a pan-specific manner, alone or in combination with HRP2, the detection of pLDH in samples with 2,000 parasites/μL was 100% for two RDTs and 80% for the other two RDTs. The mean level for detection of pLDH at 200 parasites/μl was low (29%), with a range of 0% to100%, which was partly attributable to weak initial baseline reactivity. Reactivity of dried 3D7 at 1,000 and 2,000 parasites/μl stored at 4°C was retained at 100% for up to 52 ...
HIV infection, and potentially its treatment, increases the risk of an arterial ischemic stroke. Multiple etiologies and lack of clear case definitions inhibit progress in this field. Several etiologies, many treatable, are relevant to HIV-related stroke. To fully understand the mechanisms and the terminology used, a robust classification algorithm to help ascribe the various etiologies is needed. This consensus paper considers the strengths and limitations of current case definitions in the context of HIV infection. The case definitions for the major etiologies in HIV-related strokes were refined (e.g., varicella zoster vasculopathy and antiphospholipid syndrome) and in some instances new case definitions were described (e.g., HIV-associated vasculopathy). These case definitions provided a framework for an algorithm to help assign a final diagnosis, and help classify the subtypes of HIV etiology in ischemic stroke.,br/, OBJECTIVES: An increasing proportion of people living with HIV are older ...

This manual serves as a guide for facilitators to train village health care and clinic workers on how to use Immunochromatographic rapid diagnostic test for malaria. It also describes the appropriate steps to take for treating a patient after he or she tests positive or negative for the disease.
Rapid diagnostic tests (RDTs) are used to detect in a few minutes the presence of an infection (HIV, malaria, mononucleosis, tonsillitis, etc.), an immune status (tetanus immunity), a physiological situation (e.g. pregnancy), an acute pathological situation (rupture of fetal membranes, myocardial infarction) or the presence of drugs in urine or saliva. These membrane tests, based on the principle of immune-chromatography or immune-filtration, can be used with one drop of blood, serum, plasma, urine, or stool samples, vaginal swab samples or nasopharyngeal swab samples. They are mostly used as screening tools in veterinary and human medicine, and in particular answer the needs of the POC and emergency biology markets. ...

Assessment strategies in current major international guidelines focus on the detection of underlying obstructive CAD. European and American guidelines (ESC and ACC/AHA, respectively) favour a Bayesian approach whereby overall probability of obstructive CAD after testing is determined from pretest probability modified by the diagnostic test results. The ACC/AHA guidelines determine pretest risk from a modified Diamond Forrester model,30 whereas the Europeans favour the CADC (Coronary Artery Disease Consortium) model which avoids overestimation seen with Diamond-Forrester and appears a more accurate assessment of pretest risk.31 Both current guidelines stratify pretest risk into low, intermediate or high groups with use of non-invasive testing suggested in the intermediate group (ACC/AHA arbitrarily defined as 10%-90% or 15%-85% in ESC).. In stark contrast, the NICE CG95 2016 update chest pain of recent onset: assessment and diagnosis discarded the Bayesian pretest risk assessment. NICE ...
