Valuing injection frequency and other attributes of type 2 diabetes treatments in Australia: A discrete choice experiment
© 2018 The Author(s). Background: Multiple pharmacotherapy options are available to control blood glucose in Type 2 Diabetes Mellitus (T2DM). Patients and prescribers may have different preferences for T2DM treatment attributes, such as mode and frequency of administration, based on their experiences and beliefs which may impact adherence. As adherence is a pivotal issue in diabetes therapy, it is important to understand what patients value and how they trade-off the risks and benefits of new treatments. This study aims to investigate the key drivers of choice for T2DM treatments, with a focus on injection frequency, and explore patients' associated willingness-to-pay. Methods: A discrete choice experiment (DCE) was used to present patients with a series of trade-offs between different treatment options, injectable and oral medicines that were made up of 10 differing levels of attributes (frequency and mode of administration, weight change, needle type, storage, nausea, injection site reactions, hypoglycaemic events, instructions with food and cost). A sample of 171 Australian consenting adult T2DM patients, of which 58 were receiving twice-daily injections of exenatide and 113 were on oral glucose-lowering treatments, completed the national online survey. An error components model was used to estimate the relative priority and key drivers of choice patients place on different attributes and to estimate their willingness to pay for new treatments. Results: Injection frequency, weight change, and nausea were shown to be important attributes for patients receiving injections. Within this cohort, a once-weekly injection generated an additional benefit over a twice-daily injection, equivalent to a weighted total willingness to pay of AUD$22.35 per month. Conclusions: Based on the patient preferences, the importance of frequency of administration and other non-health benefits can be valued. Understanding patient preferences has an important role in health technology assessment, as the identification of the value as well as the importance weighting for each treatment attribute may assist with funding decisions beyond clinical trial outcomes
A combined GPS/Stated Choice experiment to estimate values of crash-risk reduction
This paper details the development and application of a Stated Choice (SC) experiment designed to explore motorists sensitivities to a kilometre-based charging regime focused around crash-risk reduction. Responses are gathered through a SC experiment that pivots off actual driving behaviour collected over a five week period using an in-vehicle Global Positioning System (GPS) device. This provision of greater reality using revealed preference (RP) information ensures that the alternatives in the SC experiment are embedded in reality, providing motorists with a more realistic context for their choices. The study demonstrates with the improved affordability, power and consumer familiarity with GPS devices, the integration of GPS recorded travel information with SC experiments is a now a feasible solution which can help enrich the quality of the reference alternatives in SC experiments in the future
2018 UK national guideline for the management of infection with Neisseria gonorrhoeae
This guideline offers recommendations for the diagnostic tests, treatment regimens and health promotion principles needed for the effective management of gonorrhoea in people aged 16 years and older. For individuals under the age of 16 years please see the British Association for Sexual Health and HIV (BASHH) guideline on STI and Related Conditions in Children and Young People. The guidelines are primarily aimed at level 3 sexual health services within the United Kingdom (UK) although the principles of the recommendations could be adopted at all levels
Detection of the United States Neisseria meningitidis urethritis clade in the United Kingdom, August and December 2019 - emergence of multiple antibiotic resistance calls for vigilance.
Since 2015 in the United States (US), the US Neisseria meningitidis urethritis clade (US_NmUC) has caused a large multistate outbreak of urethritis among heterosexual males. Its 'parent' strain caused numerous outbreaks of invasive meningococcal disease among men who have sex with men in Europe and North America. We highlight the arrival and dissemination of US_NmUC in the United Kingdom and the emergence of multiple antibiotic resistance. Surveillance systems should be developed that include anogenital meningococci
Inotropic effect of nicardipine in patients with heart failure: Assessment by left ventricular end-systolic pressure-volume analysis
AbstractNicardipine, a new dihydropyridine calcium channel blocker, has been investigated for the treatment of coronary artery disease and heart failure. To assess the inotropic effect of nicardipine in humans independent of its vasodilator effect, equihypotensive doses of intravenous nitroprusside (mean infusion rate 65 ± 13 Όg/min) and nicardipine (mean dose 5.2 ± 0.4 mg) were administered to 15 patients with heart failure (New York Heart Association functional classes II to IV, radionuclide left ventricular ejection fraction 0.15 ± 0.02). Left ventricular micromanometer pressure and simultaneous radionuclide left ventricular volume were obtained at baseline, during nitroprusside infusion, during a second baseline period and during nicardipine infusion.Heart rate did not change significantly with either nitroprusside or nicardipine. Mean systemic arterial pressure decreased by an average of 21 mm Hg with both drugs. A greater decrease in left ventricular end-diastolic pressure occurred with nitroprusside (27 ± 2 to 14 ± 2 mm Hg, p < 0.01) than with nicardipine (27 ± 2 to 23 ± 3 mm Hg, p < 0.05), and pulmonary capillary wedge pressure decreased significantly only with nitroprusside. Cardiac index increased from 1.8 ± 0.1 to 2.1 ± 0.1 liters/min per m2(p < 0.05) with nitroprusside and to a greater extent from 1.7 ± 0.1 to 2.4 ± 0.1 liters/min per m2(p < 0.01) with nicardipine. Left ventricular ejection fraction increased with nicardipine (0.15 ± 0.01 to 0.19 ± 0.01, p < 0.01), but not with nitroprusside.Peak positive first derivative of left ventricular pressure (dP/dt) decreased by 9% with both agents. Left ventricular pressure-volume loops were constructed for 14 patients. In 12 patients, the left ventricular end-systolic pressure-volume relation was shifted rightward with nicardipine, indicating a negative inotropic effect, with no shift in the remaining 2 patients.Thus, nicardipine has a negative inotropic effect in patients with heart failure. Despite this effect, left ventricular ejection fraction and cardiac index increased with nicardipine. This overall improvement in ventricular systolic performance was due to a reduction in afterload
A Prospective Randomized Comparison of a Single Antibiotic (Moxalactam) Versus Combination Therapy (Gentamicin and Clindamycin) in Penetrating Abdominal Trauma
From July 1 to December 31, 1983, 50 consecutive patients undergoing abdominal exploration for penetrating abdominal trauma from stab and gunshot wounds were prospectively randomized to receive postinjury, preoperative antibiotic coverage with moxalactam (2 g intravenously every 12 hours) or a combination of gentamicin (3 to 5 mg/kg/day in three equal doses administered every eight hours) and clindamycin (600 mg intravenously every six hours). No intraabdominal abscesses or wound infections developed, and no direct evidence of toxicity of the antibiotic regimens developed in either group. In the study group, moxalactam therapy was an effective alternative to the combination antibiotic regimen. The subsequently documented incidence of moxalactam-induced bleeding episodes precludes its use as a primary preventive antibiotic; however, other less toxic cephalosporins may demonstrate similar effectiveness
Just Google it! Impact of media coverage of an outbreak of high-level azithromycin-resistant Neisseria gonorrhoeae on online searches, and attendances, testing and diagnoses at sexual health clinics in England between 2015 and 2016: an interrupted time series analysis using surveillance data
Objectives To determine if media coverage of an outbreak of high-level azithromycin-resistant Neisseria gonorrhoeae (HL-AziR) impacted online search interest or was temporally associated with health-seeking behaviours in several English cities.
Methods A descriptive analysis of outbreak-related online media articles and relative search interest (RSI) using Google and an interrupted time series analysis using routine surveillance data from sexual health clinics (SHCs) in England (GUMCAD STI surveillance system). The main outcomes were adjusted incidence rate ratios (IRRs) of weekly attendances, gonorrhoea tests and diagnoses of gonorrhoea or âany STIâ in selected cities after media coverage of the outbreak in 2015 and 2016.
Results RSI for outbreak-related terms peaked during media coverage in September 2015 with smaller peaks coinciding with subsequent coverage. The greatest increase in RSI was in Leeds, which coincided with a 63% rise (n=1932; IRR 1.26, 95%âCI 1.12 to 1.43) in SHC attendances by women. There was only a 7% (n=1358; IRR 1.01, 95%âCI 0.91 to 1.11) increase in attendances by men. Modest increases in outcomes occurred in four other cities with a high RSI. There was no evidence of increases in outcomes in cities, other than Leeds, after subsequent media coverage of the outbreak.
Conclusions National and local media coverage of the HL-AziR outbreak coincided with peak RSI for related terms, and a transient increase in attendances, gonorrhoea tests and diagnoses of gonorrhoea or âany STIâ in some cities with a high RSI. Our analysis demonstrates the potential for media coverage to influence health-seeking behaviours during high-profile STI outbreaks
Is previous azithromycin treatment associated with azithromycin resistance inNeisseria gonorrhoeae? A cross-sectional study using national surveillance data in England
OBJECTIVES: It has been suggested that treatment of STIs with azithromycin may facilitate development of azithromycin resistance inNeisseria gonorrhoeae(NG) by exposing the organism to suboptimal doses. We investigated whether treatment history for non-rectalChlamydia trachomatis(CT), non-gonococcal urethritis (NGU) or NG (proxies for azithromycin exposure) in sexual health (GUM) services was associated with susceptibility of NG to azithromycin. METHODS: Azithromycin susceptibility data from the Gonococcal Resistance to Antimicrobials Surveillance Programme (GRASP 2013-2015, n=4606) and additional high-level azithromycin-resistant isolates (HL-AziR) identified by the Public Health England reference laboratory (2013-2016, n=54) were matched to electronic patient records in the national GUMCAD STI surveillance dataset (2012-2016). Descriptive and regression analyses were conducted to examine associations between history of previous CT/NGU/NG and subsequent susceptibility of NG to azithromycin. RESULTS: Modal azithromycin minimum inhibitory concentration (MIC) was 0.25âmg/L (one dilution below the resistance breakpoint) in those with and without history of previous CT/NGU/NG (previous 1âmonth/6 months). There were no differences in MIC distribution by history of CT/NGU (P=0.98) or NG (P=0.85) in the previous 1âmonth/6 months or in the odds of having an elevated azithromycin MIC (>0.25âmg/L) (Adjusted OR for CT/NGU 0.97 (95% CI 0.76 to 1.25); adjusted OR for NG 0.82 (95% CI: 0.65 to 1.04)) compared with those with no CT/NGU/NG in the previous 6 months. Among patients with HL-AziR NG, 3 (4%) were treated for CT/NGU and 2 (3%) for NG in the previous 6 months, compared with 6% and 8%, respectively for all GRASP patients. CONCLUSIONS: We found no evidence of an association between previous treatment for CT/NGU or NG in GUM services and subsequent presentation with an azithromycin-resistant strain. As many CT diagnoses occur in non-GUM settings, further research is needed to determine whether azithromycin-resistant NG is associated with azithromycin exposure in other settings and for other conditions
âItâs my dream to work with Olympic athletesâ: Neophyte sport psychologistsâ expectations and initial experiences regarding service delivery
We examined trainee practitioners' initial experiences of applied sport psychology practice. Semi-structured interviews (4) were conducted over 6 months with 7 full-time MSc students before, during, and after the applied sport psychology module, when they were working with clients. Participants also kept reflective diaries over an 8-week period whilst working with clients. Findings included: (a) motivations and expectations of an ASP practice career, (b) perceptions of service delivery, (c) emotional demands, and (d) pivotal experiences. Findings extend previous literature on the initial stages of practitioner development, providing micro-level detail on aspects of the intense development process during this pivotal perio
