RESUMO

BACKGROUND: Large-scale improvement programmes are a frequent response to quality and safety problems in health systems globally, but have mixed impact. The extent to which they meet criteria for programme quality, particularly in relation to transparency of reporting and evaluation, is unclear. AIM: To identify large-scale improvement programmes focused on intrapartum care implemented in English National Health Service maternity services in the period 2010-2023, and to conduct a structured quality assessment. METHODS: We drew on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews guidance to inform the design and reporting of our study. We identified relevant programmes using multiple search strategies of grey literature, research databases and other sources. Programmes that met a prespecified definition of improvement programme, that focused on intrapartum care and that had a retrievable evaluation report were subject to structured assessment using selected features of programme quality. RESULTS: We identified 1434 records via databases and other sources. 14 major initiatives in English maternity services could not be quality assessed due to lack of a retrievable evaluation report. Quality assessment of the 15 improvement programmes meeting our criteria for assessment found highly variable quality and reporting. Programme specification was variable and mostly low quality. Only eight reported the evidence base for their interventions. Description of implementation support was poor and none reported customisation for challenged services. None reported reduction of inequalities as an explicit goal. Only seven made use of explicit patient and public involvement practices, and only six explicitly used published theories/models/frameworks to guide implementation. Programmes varied in their reporting of the planning, scope and design of evaluation, with weak designs evident. CONCLUSIONS: Poor transparency of reporting and weak or absent evaluation undermine large-scale improvement programmes by limiting learning and accountability. This review indicates important targets for improving quality in large-scale programmes.

RESUMO

OBJECTIVES: Despite their widespread use, the evidence base for the effectiveness of quality improvement collaboratives remains mixed. Lack of clarity about 'what good looks like' in collaboratives remains a persistent problem. We aimed to identify the distinctive features of a state-wide collaboratives programme that has demonstrated sustained improvements in quality of care in a range of clinical specialties over a long period. DESIGN: Qualitative case study involving interviews with purposively sampled participants, observations and analysis of documents. SETTING: The Michigan Collaborative Quality Initiatives programme. PARTICIPANTS: 38 participants, including clinicians and managers from 10 collaboratives, and staff from the University of Michigan and Blue Cross Blue Shield of Michigan. RESULTS: We identified five features that characterised success in the collaboratives programme: learning from positive deviance; high-quality coordination; high-quality measurement and comparative performance feedback; careful use of motivational levers; and mobilising professional leadership and building community. Rigorous measurement, securing professional leadership and engagement, cultivating a collaborative culture, creating accountability for quality, and relieving participating sites of unnecessary burdens associated with programme participation were all important to high performance. CONCLUSIONS: Our findings offer valuable learning for optimising collaboration-based approaches to improvement in healthcare, with implications for the design, structure and resourcing of quality improvement collaboratives. These findings are likely to be useful to clinicians, managers, policy-makers and health system leaders engaged in multiorganisational approaches to improving quality and safety.

RESUMO

BACKGROUND: Coronary microvascular dysfunction may cause myocardial ischemia with no obstructive coronary artery disease (INOCA). If functional testing is not performed INOCA may pass undetected. Stress perfusion cardiovascular MRI (CMR) quantifies myocardial blood flow (MBF) but the clinical utility of stress CMR in the management of patients with suspected angina with no obstructive coronary arteries (ANOCA) is uncertain. OBJECTIVES: First, to undertake a diagnostic study using stress CMR in patients with ANOCA following invasive coronary angiography and, second, in a nested, double-blind, randomized, controlled trial to assess the effect of disclosure on the final diagnosis and health status in the longer term. DESIGN: All-comers referred for clinically indicated coronary angiography for the investigation of suspected coronary artery disease will be screened in 3 regional centers in the United Kingdom. Following invasive coronary angiography, patients with ANOCA who provide informed consent will undergo noninvasive endotyping using stress CMR within 3 months of the angiogram. DIAGNOSTIC STUDY: Stress perfusion CMR imaging to assess the prevalence of coronary microvascular dysfunction and clinically significant incidental findings in patients with ANOCA. The primary outcome is the between-group difference in the reclassification rate of the initial diagnosis based on invasive angiography versus the final diagnosis after CMR imaging. RANDOMIZED, CONTROLLED TRIAL: Participants will be randomized to inclusion (intervention group) or exclusion (control group) of myocardial blood flow to inform the final diagnosis. The primary outcome of the clinical trial is the mean within-subject change in the Seattle Angina Questionnaire summary score (SAQSS) at 6 months. Secondary outcome assessments include the EUROQOL EQ-5D-5L questionnaire, the Brief Illness Perception Questionnaire (Brief-IPQ), the Treatment Satisfaction Questionnaire (TSQM-9), the Patient Health Questionnaire-4 (PHQ-4), the Duke Activity Status Index (DASI), the International Physical Activity Questionnaire- Short Form (IPAQ-SF), the Montreal Cognitive Assessment (MOCA) and the 8-item Productivity Cost Questionnaire (iPCQ). Health and economic outcomes will be assessed using electronic healthcare records. VALUE: To clarify if routine stress perfusion CMR imaging reclassifies the final diagnosis in patients with ANOCA and whether this strategy improves symptoms, health-related quality of life and health economic outcomes. CLINICALTRIALS: GOV: NCT04805814.

RESUMO

BACKGROUND: Workplace programmes to test staff for asymptomatic COVID-19 infection have become common, but raise a number of ethical challenges. In this article, we report the findings of a consultation that informed the development of an ethical framework for organisational decision-making about such programmes. METHODS: We conducted a mixed-method consultation - a survey and semi-structured interviews during November-December 2020 in a UK case study organisation that had introduced asymptomatic testing for all staff working on-site in its buildings. Analysis of closed-ended survey data was conducted descriptively. An analysis approach based on the Framework Method was used for the open-ended survey responses and interview data. The analyses were then integrated to facilitate systematic analysis across themes. Inferences were based on the integrated findings and combined with other inputs (literature review, ethical analysis, legal and public health guidance, expert discussions) to develop an ethical framework. RESULTS: The consultation involved 61 staff members from the case study organisation (50 survey respondents and 11 interview participants). There was strong support for the asymptomatic testing programme: 90% of the survey respondents viewed it as helpful or very helpful. Open-ended survey responses and interviews gave insight into participants' concerns, including those relating to goal drift, risk of false negatives, and potential negative impacts for household members and people whose roles lacked contractual and financial stability. Integration of the consultation findings and the other inputs identified the importance of a whole-system approach with appropriate support for the key control measure of isolation following positive tests. The need to build trust in the testing programme, for example through effective communication from leaders, was also emphasised. CONCLUSIONS: The consultation, together with other inputs, informed an ethical framework intended to support employers. The framework may support organisational decision-making in areas ranging from design and operation of the programme through to choices about participation. The framework is likely to benefit from further consultation and refinement in new settings.

RESUMO

OBJECTIVES: Those who work in health care organisations are a potentially valuable source of information about safety concerns, yet failures of voice are persistent. We propose the concept of 'voiceable concern' and offer an empirical exploration. METHODS: We conducted a qualitative study involving 165 semi-structured interviews with a range of staff (clinical, non-clinical and at different hierarchical levels) in three hospitals in two countries. Analysis was based on the constant comparative method. RESULTS: Our analysis shows that identifying what counts as a concern, and what counts as a occasion for voice by a given individual, is not a straightforward matter of applying objective criteria. It instead often involves discretionary judgement, exercised in highly specific organisational and cultural contexts. We identified four influences that shape whether incidents, events and patterns were classified as voiceable concerns: certainty that something is wrong and is an occasion for voice; system versus conduct concerns, forgivability and normalisation. Determining what counted as a voiceable concern is not a simple function of the features of the concern; also important is whether the person who noticed the concern felt it was voiceable by them. CONCLUSIONS: Understanding how those who work in health care organisations come to recognise what counts as a voiceable concern is critical to understanding decisions and actions about speaking out. The concept of a voiceable concern may help to explain aspects of voice behaviour in organisations as well as informing interventions to improve voice.

RESUMO

OBJECTIVE: Patients with bipolar disorder have recurrent major depression, residual mood symptoms, and limited treatment options. Building on promising pilot data, the authors conducted a 6-week randomized double-blind placebo-controlled trial to investigate the efficacy of adjunctive bright light therapy at midday for bipolar depression. The aims were to determine remission rate, depression symptom level, and rate of mood polarity switch, as well as to explore sleep quality. METHOD: The study enrolled depressed adults with bipolar I or II disorder who were receiving stable dosages of antimanic medication (excluding patients with hypomania or mania, mixed symptoms, or rapid cycling). Patients were randomly assigned to treatment with either 7,000-lux bright white light or 50-lux dim red placebo light (N=23 for each group). Symptoms were assessed weekly with the Structured Interview Guide for the Hamilton Depression Scale With Atypical Depression Supplement (SIGH-ADS), the Mania Rating Scale, and the Pittsburgh Sleep Quality Index. Remission was defined as having a SIGH-ADS score of 8 or less. RESULTS: At baseline, both groups had moderate depression and no hypomanic or manic symptoms. Compared with the placebo light group, the group treated with bright white light experienced a significantly higher remission rate (68.2% compared with 22.2%; adjusted odds ratio=12.6) at weeks 4-6 and significantly lower depression scores (9.2 [SD=6.6] compared with 14.9 [SD=9.2]; adjusted ß=-5.91) at the endpoint visit. No mood polarity switches were observed. Sleep quality improved in both groups and did not differ significantly between them. CONCLUSIONS: The data from this study provide robust evidence that supports the efficacy of midday bright light therapy for bipolar depression.

RESUMO

James McGowan, R&D product designer for Monodraught, a specialist in 'natural ventilation, natural daylight, and natural cooling systems', discusses the development of Cool-phase, the company's latest innovative application of phase change material (PCM) as a thermal energy store used to actively ventilate and cool buildings. As he explains, when the company decided to re-design an already successful product to further enhance its performance, the use of 3D modelling greatly speeded up prototyping, and helped the design process progress considerably more quickly.

RESUMO

Unintended pregnancy is a global sexual health problem. Outcomes of unintended pregnancy include unwanted childbirth and abortion, which may be associated with negative physical and psychosocial health implications for women. In Scotland, the Scottish Sexual Health Strategy has the stated goal of improving the sexual health of the people of Scotland. One aim of the Strategy is to reduce rates of unintended pregnancy and one policy designed to achieve this is 'widening access to emergency contraception'. This paper examines the success of this policy with reference to the implicit link it makes between expanding access to emergency contraception and increasing its effective use, aiming thereby to reduce rates of unintended pregnancy. Since there is evidence that previous policies and strategies expanding access to emergency contraception have failed to reduce such rates, alternative approaches to achieve a reduction in unintended pregnancies are discussed.

RESUMO

BACKGROUND: Patients prescribed opioids for chronic pain may suffer from inadequate postoperative pain control. Ketamine is an adjuvant demonstrating analgesic and opioid-sparing effects. We hypothesize that an intravenous ketamine infusion in addition to opioid-based patient-controlled analgesia (PCA) improves postoperative pain relief in this patient population. METHODS: We evaluated 64 patients with chronic pain taking opioids undergoing nononcologic surgery. Patients were randomized to receive either postoperative hydromorphone PCA and continuous ketamine (0.2 mg/kg/hour), or hydromorphone PCA and saline. Patients provided numeric rating scale (NRS) pain scores for "worst," "average," and "least" pain following surgery. The primary outcome measure was change in patients' postoperative NRS scores compared with baseline NRS. Secondary and tertiary outcomes included postoperative day one 24-hour opioid use and the amount of opioid used 24 hours prior to hospital discharge. RESULTS: Fifty-nine patients were included in the analysis. Baseline patient characteristics were similar with the exception of age. Patients using ketamine had decreased "average" pain scores (percent change between postoperative and preoperative NRS) after surgery (13.5% decrease in the ketamine group vs 15.5% increase in NRS in the placebo group, P = 0.0057). There were no differences in "worst" or "least" pain scores or postoperative opioid use. Side effects between groups were similar. CONCLUSIONS: Our study demonstrates that a postoperative ketamine infusion at 0.2 mg/kg/hour in addition to opioids results in a statistically significant reduction of "average" pain scores in patients undergoing surgery who take opioids for chronic pain. However, "least" and "worst" pain scores and the amount of opioid used postoperatively did not differ between groups. Thus, the use of a postoperative ketamine infusion at 0.2 mg/kg/hour provides limited benefit in improving pain management for this challenging population.

RESUMO

BACKGROUND: Academic medical centers are faced with increasing volumes, higher acuity, and, as a consequence, capacity issues. These affect operating room (OR) use and patient throughput, with negative impact on finances and patient and physician satisfaction. We evaluated our experiences in dealing with OR efficiency at a time of maximum hospital capacity and occupancy. STUDY DESIGN: Using a multidisciplinary approach, we put in place seven agreed-upon strategies: daily communication, improved bed planning, discharge by noon program, internal staffing pool, special assignments for a patient transition unit, incentives, and stepped up environmental services. RESULTS: After institution of these strategies, we were able to realize a gain in OR patient volume of 8% and a decrease in OR holds of 37%. This resulted in a decrease in canceled OR cases from 4.3% to 3.1%. CONCLUSIONS: Academic medical centers face occupancy issues that are not likely to go away and will have an impact on OR volume and productivity. To improve the situation in a short-term fashion, a multidisciplinary approach involving several strategies will be needed.

RESUMO

Microsatellites have proved to be very useful as genetic markers, as they seem to be ubiquitous and randomly distributed throughout most eukaryote genomes. However, our laboratories and others have determined that this paradigm does not necessarily apply to the yellow fever mosquito Aedes aegypti. We report the isolation and identification of microsatellite sequences from multiple genomic libraries for A. aegypti. We identified 6 single-copy simple microsatellites from 3 plasmid libraries enriched for (GA)(n), (AAT)(n), and (TAGA)(n) motifs from A. aegypti. In addition, we identified 5 single-copy microsatellites from an A. aegypti cosmid library. Genetic map positions were determined for 8 microsatellite loci. These markers greatly increase the number of microsatellite markers available for A. aegypti and provide additional tools for studying genetic variability of mosquito populations. Additionally, most A. aegypti microsatellites are closely associated with repetitive elements that likely accounts for the limited success in developing an extensive panel of microsatellite marker loci.

RESUMO

Heart failure is the most common malignant disease in the developed world. Levosimendan (Simdax) is a novel intravenous agent that exerts inotropic effects through sensitization of myofilaments to calcium and vasodilator effects by opening ATP-dependent potassium channels on vascular smooth muscle. Infusion of levosimendan increases cardiac output due to an increase in stroke volume and heart rate, with a fall in pulmonary capillary wedge pressure. It has an active metabolite with a half-life of about 80 h, therefore infusions of 6 to 24 h result in hemodynamic effects that persist for 7 to 10 days. Preliminary observations suggest that a single infusion of levosimendan lasting 6 to 24 h in patients with severe heart failure due to left ventricular systolic dysfunction results in hemodynamic changes, symptomatic benefit and a reduction in morbidity and mortality over the following 2 to 4 weeks compared with placebo in one study and with dobutamine in another. Long-term follow-up suggests no loss of this early benefit over 6 months. Levosimendan is licensed for the treatment of decompensated heart failure in many countries but not in North America. Further large trials are being conducted comparing levosimendan with placebo and with dobutamine in patients with severe heart failure and left ventricular systolic dysfunction. If these studies confirm the benefits of levosimendan, then it may become routine therapy for the management of severe heart failure.

RESUMO

BACKGROUND: An accurate assessment of left ventricular (LV) systolic function is of central importance to the diagnosis and management of heart failure. Echocardiography is currently the technique most widely used for this purpose. METHODS: A systematic review was performed of the evidence for the accuracy of 3 echocardiographic methods--Simpson's rule, wall motion index (WMI), and subjective visual assessment--compared with radionuclide or contrast ventriculography for the assessment of LV ejection fraction (LVEF). RESULTS: Twenty-five studies were identified in which data on agreement between echocardiography and reference methods were obtainable. A further 18 studies provided correlation data alone. For Simpson's rule, Bland-Altman limits of agreement (95% CI) ranged from LVEF +/-7% to +/-25% (median +/-18%); for WMI +/-13% to +/-20% (median +/-16%); and for subjective visual assessment +/-16% to +/-24% (median +/-19%). Subject echogenicity, the nature of underlying disease, and the use of additional imaging technology, including secondary harmonic imaging and contrast agents, is likely to influence the accuracy of different methods. No method appears to systematically under- or overestimate LVEF to any major extent. CONCLUSION: These findings have important implications for the investigation of heart failure and for the practice and reporting of echocardiography.

RESUMO

Levosimendan is a new inotropic and vasodilator agent. The inotropic effect is mediated by calcium concentration-dependent conformational changes in troponin C during systole leading to sensitization of the contractile apparatus to calcium ions. The vasodilator effect is mediated by opening potassium channels on vascular smooth muscle. It has a complex pharmacokinetic profile, with a long-acting metabolite that has hemodynamic effects persisting for approximately 1 week. Although it is absorbed orally, it has been developed only for intravenous use thus far. The hemodynamic effects are not reduced and may be enhanced in the presence of beta-blockers, possibly an important attribute when dealing with exacerbation of heart failure caused by or in the presence of beta-blockers. More patients with heart failure have participated in randomized controlled trials of levosimendan than of any other intravenous inotropic agent. Experience with its use after cardiac surgery is limited. Preliminary observations suggest that hemodynamic changes are associated with symptomatic benefit and a reduction in morbidity and mortality in patients with severe heart failure caused by left ventricular systolic dysfunction, compared with placebo in one study and dobutamine in another. Levosimendan may be the first inotropic agent that it is both safe and effective in altering clinical outcomes relevant for patients. Part of this benefit may be achieved because levosimendan allows other inotropic agents that may have adverse effects on patient outcome to be avoided. Further research is required to confirm whether levosimendan reduces mortality and morbidity compared with a placebo and when administered repetitively. If it does, it may become routine therapy for the treatment of severe heart failure.
