General practitioners' views on use of patient reported outcome measures in primary care: a cross-sectional survey and qualitative study.
No full textBACKGROUND
Patient reported outcome measures (PROMs) are increasingly used to assess impact of disease and treatment on quality of life and symptoms; however, their use in primary care is fragmented. We aimed to understand how PROMs are currently being used in primary care, the barriers and facilitators of this use and if appropriate how it might be optimised.
METHODS
Cross-sectional survey and semi-structured interviews among general practitioners (GPs) in England. GPs' opinions were explored using an electronic, self-completed questionnaire disseminated to 100 GPs via an online doctors' community and semi-structured qualitative interviews with 25 GPs.
RESULTS
Most GPs surveyed (77/100; 77%) reported using one or more PROM, primarily to aid clinical management (n = 66) or as screening/diagnostic tools (n = 62). Qualitative interviews highlighted challenges in identifying and selecting PROMs; however, some GPs valued PROMs for shared decision making and to direct patient discussions. The interviews identified key barriers to PROM use including: time constraints; insufficient knowledge; lack of integration into clinical systems; and PROMs being mandated without consultation or explanation. Evidence of the benefit of PROMs is required to promote uptake and use of PROMs in primary care.
CONCLUSION
Implementation of PROMs in primary care requires integration with clinical systems, a bottom-up approach to PROM selection and system design involving meaningful consultation with patients and primary care clinicians and training/support for use
Effect of age on the relative efficacy of clozapine in schizophrenia.
No full textOBJECTIVE
Early treatment of schizophrenia improves outcomes. Clozapine appears to have unique benefit when other antipsychotic medication has failed. This systematic review and meta-analysis aims to assess clozapine's superiority over alternative antipsychotic medication and examine whether earlier use is associated with additional benefit.
METHOD
Systematic retrieval of blinded, randomized controlled trials comparing clozapine with alternative antipsychotics in adults with schizophrenia. The effect of mean age on relative clozapine response was examined using random effects meta-regression, and multiple linear regression on available patient data.
RESULTS
276 studies were retrieved. Thirty-four studies were included in the meta-analysis. Clozapine was significantly more effective than alternative antipsychotics in reducing psychotic symptoms and increasing response. However, meta-regression failed to show a more significant effect in younger patients (age on effect size (total psychotic symptoms) 0.00, p =0.79 CI -0.03 - 0.03). Individual patient data was available for 2 studies, the larger of which showed a significant interaction between younger age and superiority of clozapine.
CONCLUSION
The results support clozapine's superiority over other antipsychotics. A convincing effect of age on this effect was not demonstrated, although this was suggested in one study. In view of the age of many of the included studies, and changes in reporting practice over time, new clozapine RCTs, which include age of illness onset as well as age at trial time, would be welcome in order to provide meta-analysable data for future use
Guide to preclinical models used to study the pathophysiology of idiopathic intracranial hypertension.
No full textIdiopathic intracranial hypertension (IIH) is characterised by raised intracranial pressure (ICP) and papilloedema in the absence of an identifiable secondary cause typically occurring in young women with obesity. The impact is considerable with the potential for blindness, chronic disabling headaches, future risk of cardiovascular disease and marked healthcare utilisation. There have been marked advances in our understanding the pathophysiology of IIH including the role of androgen excess. Insight into pathophysiological underpinnings has arisen from astute clinical observations, studies, and an array of preclinical models. This article summarises the current literature pertaining to the pathophysiology of IIH. The current preclinical models relevant to gaining mechanistic insights into IIH are then discussed. In vitro and in vivo models which study CSF secretion and the effect of potentially pathogenic molecules have started to glean important mechanistic insights. These models are also useful to evaluate novel therapeutic targets to abrogate CSF secretion. Importantly, in vitro CSF secretion assays translate into relevant changes in ICP in vivo. Models of CSF absorption pertinent to IIH, are less well established but highly relevant and of future interest. There is no fully developed in vivo model of IIH but this remains an area of importance. Progress is being made to improve our understanding of the underlying aetiology in IIH including the characterisation of disease biomarkers and their mechanistic role in driving disease pathology. Preclinical models, used to evaluate IIH mechanisms are yielding important mechanistic insights. Further work to refine these techniques will provide translatable insights into disease aetiology
Investigating Swallowing and Tracheostomy Following Critical Illness: A Scoping Review.
No full textOBJECTIVES
Tracheostomy and dysphagia often coexist during critical illness; however, given the patient's medical complexity, understanding the evidence to optimize swallowing assessment and intervention is challenging. The objective of this scoping review is to describe and explore the literature surrounding swallowing and tracheostomy in the acute care setting.
DATA SOURCES
Eight electronic databases were searched from inception to May 2017 inclusive, using a search strategy designed by an information scientist. We conducted manual searching of 10 journals, nine gray literature repositories, and forward and backward citation chasing.
STUDY SELECTION
Two blinded reviewers determined eligibility according to inclusion criteria: English-language studies reporting on swallowing or dysphagia in adults (≥ 17 yr old) who had undergone tracheostomy placement while in acute care. Patients with head and/or neck cancer diagnoses were excluded.
DATA EXTRACTION
We extracted data using a form designed a priori and conducted descriptive analyses.
DATA SYNTHESIS
We identified 6,396 citations, of which 725 articles were reviewed and 85 (N) met inclusion criteria. We stratified studies according to content domains with some featuring in multiple categories: dysphagia frequency (n = 38), swallowing physiology (n = 27), risk factors (n = 31), interventions (n = 21), and assessment comparisons (n = 12) and by patient etiology. Sample sizes (with tracheostomy) ranged from 10 to 3,320, and dysphagia frequency ranged from 11% to 93% in studies with consecutive sampling. Study design, sampling method, assessment methods, and interpretation approach varied significantly across studies.
CONCLUSIONS
The evidence base surrounding this subject is diverse, complicated by heterogeneous patient selection methods, design, and reporting. We suggest ways the evidence base may be developed
Patient advocacy in head and neck cancer: realities, challenges and the role of the multi-disciplinary team.
No full textThis paper explores the concept of advocacy in head and neck cancer. We define inherent challenges in the development and success of advocacy within this context, and offer ways to embed it within clinical practice. We outline what advocacy is, ways in which it may benefit people with head and neck cancer and the engagement required from health care professionals to facilitate advocacy to improve outcomes

No full textMicronized vaginal progesterone to prevent miscarriage: a critical evaluation of randomized evidence.
No full textProgesterone is essential for the maintenance of pregnancy. Several small trials have suggested that progesterone supplementation may reduce the risk of miscarriage in women with recurrent or threatened miscarriage. Cochrane Reviews summarized the evidence and found that the trials were small with substantial methodologic weaknesses. Since then, the effects of first-trimester use of vaginal micronized progesterone have been evaluated in 2 large, high-quality, multicenter placebo-controlled trials, one targeting women with unexplained recurrent miscarriages (the PROMISE [PROgesterone in recurrent MIScarriagE] trial) and the other targeting women with early pregnancy bleeding (the PRISM [PRogesterone In Spontaneous Miscarriage] trial). The PROMISE trial studied 836 women from 45 hospitals in the United Kingdom and the Netherlands and found a 3% greater live birth rate with progesterone but with substantial statistical uncertainty. The PRISM trial studied 4153 women from 48 hospitals in the United Kingdom and found a 3% greater live birth rate with progesterone, but with a P value of .08. A key finding, first observed in the PROMISE trial, and then replicated in the PRISM trial, was that treatment with vaginal micronized progesterone 400 mg twice daily was associated with increasing live birth rates according to the number of previous miscarriages. Prespecified PRISM trial subgroup analysis in women with the dual risk factors of previous miscarriage(s) and current pregnancy bleeding fulfilled all 11 conditions for credible subgroup analysis. For the subgroup of women with a history of 1 or more miscarriage(s) and current pregnancy bleeding, the live birth rate was 75% (689/914) with progesterone vs 70% (619/886) with placebo (rate difference 5%; risk ratio, 1.09, 95% confidence interval, 1.03-1.15; P=.003). The benefit was greater for the subgroup of women with 3 or more previous miscarriages and current pregnancy bleeding; live birth rate was 72% (98/137) with progesterone vs 57% (85/148) with placebo (rate difference 15%; risk ratio, 1.28, 95% confidence interval, 1.08-1.51; P=.004). No short-term safety concerns were identified from the PROMISE and PRISM trials. Therefore, women with a history of miscarriage who present with bleeding in early pregnancy may benefit from the use of vaginal micronized progesterone 400 mg twice daily. Women and their care providers should use the findings for shared decision-making
Prophylaxis and management of graft versus host disease after stem-cell transplantation for haematological malignancies: updated consensus recommendations of the European Society for Blood and Marrow Transplantation.
No full textGraft-versus-host disease (GVHD) is a major factor contributing to mortality and morbidity after allogeneic stem-cell transplantation. Because of the small number of results from well designed, large-scale, clinical studies there is considerable variability in the prevention and treatment of GVHD worldwide. In 2014, to standardise treatment approaches the European Society of Blood and Marrow Transplantation published recommendations on the management of GVHD in the setting of HLA-identical sibling or unrelated donor transplantation in adult patients with haematological malignancies. Here we update these recommendations including the results of study published after 2014. Evidence was searched in three steps: first, a widespread scan of published trials, meta-analyses, and systematic reviews; second, expert opinion was added for specific issues following several rounds of debate; and third, a refined search to target debated or rapidly updating issues. On the basis of this evidence and the 2014 recommendations, five members of the EBMT Transplant Complications Working Party created 38 statements on GVHD prophylaxis, drug management, and treatment of acute and chronic GVHD. Subsequently, they created the EBMT GVHD management recommendation expert panel by recruiting 20 experts with expertise in GVHD management. An email-based, two-round Delphi panel approach was used to manage the consensus. Modified National Comprehensive Cancer Network categories for evidence and consensus were applied to the approved statements. We reached 100% consensus for 29 recommendations and 95% consensus for nine recommendations. Key updates to these recommendations include a broader use of rabbit anti-T-cell globulin; lower steroid doses for the management of grade 2 acute GVHD with isolated skin or upper gastrointestinal tract manifestations; fluticasone, azithromycin, and montelukast should be used for bronchiolitis obliterans syndrome; and the addition of newer treatment options for resteroid-refractory acute and chronic GVHD. In addition, we discuss specific aspects of GVHD prophylaxis and management in the setting of haploidentical transplantation and in paediatric patients, but no formal recommendations on those procedures have been provided in this Review. The European Society of Blood and Marrow Transplantation proposes to use these recommendations as a basis for the routine management of GVHD during stem-cell transplantation
