Prenatal Screening and Genetics
Although the term 'genetic screening' has been used for decades, this paper discusses how, in its most precise meaning, genetic screening has not yet been widely introduced. 'Prenatal screening' is often confused with 'genetic screening'. As we show, these terms have different meanings, and we examine definitions of the relevant concepts in order to illustrate this point. The concepts are i) prenatal, ii) genetic screening, iii) screening, scanning and testing, iv) maternal and foetal tests, v) test techniques and vi) genetic conditions. So far, prenatal screening has little connection with precisely defined genetics. There are benefits but also disadvantages in overstating current links between them in the term genetic screening. Policy making and professional and public understandings about screening could be clarified if the distinct meanings of prenatal screening and genetic screening were more precisely observed
Levels of State and Trait Anxiety in Patients Referred to Ophthalmology by Primary Care Clinicians: A Cross Sectional Study
Purpose There is a high level of over-referral from primary eye care leading to significant numbers of people without ocular pathology (false positives) being referred to secondary eye care. The present study used a psychometric instrument to determine whether there is a psychological burden on patients due to referral to secondary eye care, and used Rasch analysis to convert the data from an ordinal to an interval scale. Design Cross sectional study. Participants and Controls 322 participants and 80 control participants. Methods State (i.e. current) and trait (i.e. propensity to) anxiety were measured in a group of patients referred to a hospital eye department in the UK and in a control group who have had a sight test but were not referred. Response category analysis plus infit and outfit Rasch statistics and person separation indices were used to determine the usefulness of individual items and the response categories. Principal components analysis was used to determine dimensionality. Main Outcome Measure Levels of state and trait anxiety measured using the State-Trait Anxiety Inventory. Results State anxiety scores were significantly higher in the patients referred to secondary eye care than the controls (p0.1). Rasch analysis highlighted that the questionnaire results needed to be split into “anxiety-absent” and “anxiety-present” items for both state and trait anxiety, but both subscales showed the same profile of results between patients and controls. Conclusions State anxiety was shown to be higher in patients referred to secondary eye care than the controls, and at similar levels to people with moderate to high perceived susceptibility to breast cancer. This suggests that referral from primary to secondary eye care can result in a significant psychological burden on some patients
On deciding to have a lobotomy:either lobotomies were justified or decisions under risk should not always seek to maximise expected utility
In the 1940s and 1950s thousands of lobotomies were performed on people with mental disorders. These operations were known to be dangerous, but thought to offer great hope. Nowadays, the lobotomies of the 1940s and 1950s are widely condemned. The consensus is that the practitioners who employed them were, at best, misguided enthusiasts, or, at worst, evil. In this paper I employ standard decision theory to understand and assess shifts in the evaluation of lobotomy. Textbooks of medical decision making generally recommend that decisions under risk are made so as to maximise expected utility (MEU) I show that using this procedure suggests that the 1940s and 1950s practice of psychosurgery was justifiable. In making sense of this finding we have a choice: Either we can accept that psychosurgery was justified, in which case condemnation of the lobotomists is misplaced. Or, we can conclude that the use of formal decision procedures, such as MEU, is problematic
A qualitative study of cardiovascular disease risk communication in NHS Health Check using different risk calculators: protocol for the RIsk COmmunication in NHS Health Check (RICO) study. BMC family practice, 20(1), 11.
Background
NHS Health Check is a national cardiovascular disease (CVD) risk assessment programme for 40–74 year olds in England, in which practitioners should assess and communicate CVD risk, supported by appropriate risk-management advice and goal-setting. This requires effective communication, to equip patients with knowledge and intention to act. Currently, the QRISK®2 10-year CVD risk score is most common way in which CVD risk is estimated. Newer tools, such as JBS3, allow manipulation of risk factors and can demonstrate the impact of positive actions. However, the use, and relative value, of these tools within CVD risk communication is unknown. We will explore practitioner and patient CVD risk perceptions when using QRISK®2 or JBS3, the associated advice or treatment offered by the practitioner, and patients’ responses.
Methods
RIsk COmmunication in NHS Health Check (RICO) is a qualitative study with quantitative process evaluation. Twelve general practices in the West Midlands of England will be randomised to one of two groups: usual practice, in which practitioners use QRISK®2 to assess and communicate CVD risk; intervention, in which practitioners use JBS3. Twenty Health Checks per practice will be video-recorded (n = 240, 120 per group), with patients stratified by age, gender and ethnicity. Post-Health Check, video-stimulated recall (VSR) interviews will be conducted with 48 patients (n = 24 per group) and all practitioners (n = 12–18), using video excerpts to enhance participant recall/reflection. Patient medical record reviews will detect health-protective actions in the first 12-weeks following a Health Check (e.g., lifestyle referrals, statin prescription). Risk communication, patient response and intentions for health-protective behaviours in each group will be explored through thematic analysis of video-recorded Health Checks (using Protection Motivation Theory as a framework) and VSR interviews. Process evaluation will include between-group comparisons of quantitatively coded Health Check content and post-Health Check patient outcomes. Finally, 10 patients with the most positive intentions or behaviours will be selected for case study analysis (using all data sources).
Discussion
This study will produce novel insights about the utility of QRISK®2 and JBS3 to promote patient and practitioner understanding and perception of CVD risk and associated implications for patient intentions with respect to health-protective behaviours (and underlying mechanisms). Recommendations for practice will be developed
Does the routine use of global coronary heart disease risk scores translate into clinical benefits or harms? A systematic review of the literature
<p>Abstract</p> <p>Background</p> <p>Guidelines now recommend routine assessment of global coronary heart disease (CHD) risk scores. We performed a systematic review to assess whether global CHD risk scores result in clinical benefits or harms.</p> <p>Methods</p> <p>We searched MEDLINE (1966 through June 13, 2007) for articles relevant to our review. Using predefined inclusion and exclusion criteria, we included studies of any design that provided physicians with global risk scores or allowed them to calculate scores themselves, and then measured clinical benefits and/or harms. Two reviewers reviewed potentially relevant studies for inclusion and resolved disagreement by consensus. Data from each article was then abstracted into an evidence table by one reviewer and the quality of evidence was assessed independently by two reviewers.</p> <p>Results</p> <p>11 studies met criteria for inclusion in our review. Six studies addressed clinical benefits and 5 addressed clinical harms. Six studies were rated as "fair" quality and the others were deemed "methodologically limited". Two fair quality studies showed that physician knowledge of global CHD risk is associated with increased prescription of cardiovascular drugs in high risk (but not all) patients. Two additional fair quality studies showed no effect on their primary outcomes, but one was underpowered and the other focused on prescribing of lifestyle changes, rather than drugs whose prescribing might be expected to be targeted by risk level. One of these aforementioned studies showed improved blood pressure in high-risk patients, but no improvement in the proportion of patients at high risk, perhaps due to the high proportion of participants with baseline risks significantly exceeding the risk threshold. Two fair quality studies found no evidence of harm from patient knowledge of global risk scores when they were accompanied by counseling, and optional or scheduled follow-up. Other studies were too methodologically limited to draw conclusions.</p> <p>Conclusion</p> <p>Our review provides preliminary evidence that physicians' knowledge of global CHD risk scores may translate into modestly increased prescribing of cardiovascular drugs and modest short-term reductions in CHD risk factors without clinical harm. Whether these results are replicable, and translate across other practice settings or into improved long-term CHD outcomes remains to be seen.</p
A needs assessment for a minor eye condition service within Leeds, Bradford and Airedale, UK
YesBackground: There are a number of limitations to the present primary eye care system in the UK. Patients with
minor eye conditions typically either have to present to their local hospital or GP, or face a charge when visiting
eye care professionals (optometrists). Some areas of the UK have commissioned enhanced community services to
alleviate this problem; however, many areas have not. The present study is a needs assessment of three areas
(Leeds, Airedale and Bradford) without a Minor Eye Conditions Service (MECS), with the aim of determining whether
such a service is clinically or economically viable.
Method: A pro forma was developed for optometrists and practice staff to complete when a patient presented whose
reason for attending was due to symptoms indicative of a problem that could not be optically corrected. This form
captured the reason for visit, whether the patient was seen, the consultation funding, the outcome and where the
patient would have presented to if the optometrists could not have seen them. Optometrists were invited to
participate via Local Optical Committees. Results were submitted via a Google form or a Microsoft Excel document and
were analysed in Microsoft Excel.
Results: Seventy-five percent of patients were managed in optometric practice. Nine and 16% of patients required
subsequent referral to their General Practitioner or hospital ophthalmology department, respectively. Should they not
have been seen, 34% of patients would have presented to accident and emergency departments and 59% to their
general practitioner. 53% of patients paid privately for the optometrist appointment, 28% of patients received a free
examination either through use of General Ophthalmic Service sight tests (9%) or optometrist good will (19%) and
19% of patients did not receive a consultation and were redirected to other providers (e.g. pharmacy, accident and
emergency or General Practitioner). 88% of patients were satisfied with the level of service. Cost-analyses revealed a
theoretical cost saving of £3198 to the NHS across our sample for the study period, indicating cost effectiveness.
Conclusions: This assessment demonstrates that a minor eye condition service in the local areas would be economically
and clinically viable and well received by patients
"One for Sorrow, Two for Joy?": American embryo transfer guideline recommendations, practices and outcomes for gestational surrogate patients
In January 2016, Melissa Cook, a California gestational surrogate experiencing a multiple birth pregnancy following the in vitro fertilization (IVF) transfer of three embryos comprised of donor eggs and sperm provided by the intended father went to the media when the intended father requested that she undergo a fetal reduction because twins were less expensive to raise than triplets. Much of the legal interest in this case to date has centered on the enforceability of surrogacy contracts. However, the Cook case also raises troubling issues about fertility treatment practices involving gestational surrogates, twin preference, and third-party reproduction medical decision-making. This paper focuses on multipleembryo transfers in the context of U.S. surrogacy arrangements. Offering an original analysis of data obtained from the U.S. national assisted reproduction registry, it examines single- and multiple-embryo transfer trends over an eleven-year period (2003 to 2014). Findings reveal that recommended guidelines were followed in less than 42% of cases in 2014. The paper argues that ensuring equitable medical treatment for all recipients of IVF requires the adoption of treatment guidelines tailored to, and offering protections for, specific patient groups, and that, once in place, guidelines must be robustly implemente
THE PSYCHOSOCIAL IMPACT OF MASS-SCREENING FOR CARDIOVASCULAR RISK-FACTORS
In Leek, a small town in the north of the Netherlands, 428 men aged between 30–33 years were invited to take part in a screening test for cardiovascular risk factors. Questionnaires were sent to the 267 men who had participated in the screening test as well as to the 161 non-participants, in order to gain an insight into the participatory behaviour and the experience of those involved. The non-participants gave a diversity of motives for not taking part but did not admit to anxiety about finding abnormal results. More than half of the participants who replied (51%, n = 107) were found to have an ‘abnormality’—;that is they scored on one or more of cigarette smoking, overweight, hypertension, hyperlipoproteinaemia, albuminuna or glucosuria. The supplementary information provided on nutrition and smoking caused a large proportion of them to claim they had changed to a more healthy life-style after the screening test. Those who were under the impression that they had led healthy lives but were still found to have an ‘abnormality’ were often very astonished and sometimes worried about the result. The men without ‘abnormalities’ did not lead significantly healthier lives than the rest in terms of exercise, smoking, diet and so on; for them the result might have a ‘certificate of health’ effect justifying their not always healthy behaviou
The function of qualitative research
Due to the prevailing positivistic view on science, qualitative research has only a modest place within the social sciences. There is, however, a growing awareness that a purely quantitative approach is not always satisfactory. This is for instance the case in the field of research into the quality of life. This article discusses a number of theoretical and methodological aspects of qualitative research. The following issues are dealt with: the (in-depth) interview as a research method, and the classification, analysis and interpretation of qualitative data. Subsequently views on the reliability and validity of qualitative research are discussed. After discriptions of a number of fields of application, the potential value of qualitative research is illustrated with reference to recent research
