Undertaking Doctoral Research with Children and Young People with Life‐limiting or Life‐threatening Conditions

Abstract

Doctoral level research can contribute to the evidence base, particularly in under‐researched areas and numerically small fields such as children and young people's palliative care. It is acknowledged that much of what we currently do in children's and young people's palliative care is eminence‐based, rather than evidence‐based (Together for Short Lives, 2018). Whilst sharing experience and wisdom was valuable, particularly when the specialty was in its infancy, it is important now to develop an evidence base to ensure that children, young people and their families receive the highest standard of care.

Magnitude and modifiers of the weekend effect in hospital admissions: a systematic review and meta-analysis

Por: Chen · Y.-F. · Armoiry · X. · Higenbottam · C. · Cowley · N. · Basra · R. · Watson · S. I. · Tarrant · C. · Boyal · A. · Sutton · E. · Wu · C.-W. · Aldridge · C. P. · Gosling · A. · Lilford · R. · Bion · J.
Objective

To examine the magnitude of the weekend effect, defined as differences in patient outcomes between weekend and weekday hospital admissions, and factors influencing it.

Design

A systematic review incorporating Bayesian meta-analyses and meta-regression.

Data sources

We searched seven databases including MEDLINE and EMBASE from January 2000 to April 2015, and updated the MEDLINE search up to November 2017. Eligibility criteria: primary research studies published in peer-reviewed journals of unselected admissions (not focusing on specific conditions) investigating the weekend effect on mortality, adverse events, length of hospital stay (LoS) or patient satisfaction.

Results

For the systematic review, we included 68 studies (70 articles) covering over 640 million admissions. Of these, two-thirds were conducted in the UK (n=24) or USA (n=22). The pooled odds ratio (OR) for weekend mortality effect across admission types was 1.16 (95% credible interval 1.10 to 1.23). The weekend effect appeared greater for elective (1.70, 1.08 to 2.52) than emergency (1.11, 1.06 to 1.16) or maternity (1.06, 0.89 to 1.29) admissions. Further examination of the literature shows that these estimates are influenced by methodological, clinical and service factors: at weekends, fewer patients are admitted to hospital, those who are admitted are more severely ill and there are differences in care pathways before and after admission. Evidence regarding the weekend effect on adverse events and LoS is weak and inconsistent, and that on patient satisfaction is sparse. The overall quality of evidence for inferring weekend/weekday difference in hospital care quality from the observed weekend effect was rated as ‘very low’ based on the Grading of Recommendations, Assessment, Development and Evaluations framework.

Conclusions

The weekend effect is unlikely to have a single cause, or to be a reliable indicator of care quality at weekends. Further work should focus on underlying mechanisms and examine care processes in both hospital and community.

Health-related quality of life and prevalence of six chronic diseases in homeless and housed people: a cross-sectional study in London and Birmingham, England

Por: Lewer · D. · Aldridge · R. W. · Menezes · D. · Sawyer · C. · Zaninotto · P. · Dedicoat · M. · Ahmed · I. · Luchenski · S. · Hayward · A. · Story · A.
Objectives

To compare health-related quality of life and prevalence of chronic diseases in housed and homeless populations.

Design

Cross-sectional survey with an age-matched and sex-matched housed comparison group.

Setting

Hostels, day centres and soup runs in London and Birmingham, England.

Participants

Homeless participants were either sleeping rough or living in hostels and had a history of sleeping rough. The comparison group was drawn from the Health Survey for England. The study included 1336 homeless and 13 360 housed participants.

Outcome measures

Chronic diseases were self-reported asthma, chronic obstructive pulmonary disease (COPD), epilepsy, heart problems, stroke and diabetes. Health-related quality of life was measured using EQ-5D-3L.

Results

Housed participants in more deprived neighbourhoods were more likely to report disease. Homeless participants were substantially more likely than housed participants in the most deprived quintile to report all diseases except diabetes (which had similar prevalence in homeless participants and the most deprived housed group). For example, the prevalence of chronic obstructive pulmonary disease was 1.1% (95% CI 0.7% to 1.6%) in the least deprived housed quintile; 2.0% (95% CI 1.5% to 2.6%) in the most deprived housed quintile; and 14.0% (95% CI 12.2% to 16.0%) in the homeless group. Social gradients were also seen for problems in each EQ-5D-3L domain in the housed population, but homeless participants had similar likelihood of reporting problems as the most deprived housed group. The exception was problems related to anxiety, which were substantially more common in homeless people than any of the housed groups.

Conclusions

While differences in health between housed socioeconomic groups can be described as a ‘slope’, differences in health between housed and homeless people are better understood as a ‘cliff’.

Code sets for respiratory symptoms in electronic health records research: a systematic review protocol

Por: Jayatunga · W. · Stone · P. · Aldridge · R. W. · Quint · J. K. · George · J.
Introduction

Asthma and chronic obstructive pulmonary disease (COPD) are common respiratory conditions, which result in significant morbidity worldwide. These conditions are associated with a range of non-specific symptoms, which in themselves are a target for health research. Such research is increasingly being conducted using electronic health records (EHRs), but computable phenotype definitions, in the form of code sets or code lists, are required to extract structured data from these large routine databases in a systematic and reproducible way. The aim of this protocol is to specify a systematic review to identify code sets for respiratory symptoms in EHRs research.

Methods and analysis

MEDLINE and Embase databases will be searched using terms relating to EHRs, respiratory symptoms and use of code sets. The search will cover all English-language studies in these databases between January 1990 and December 2017. Two reviewers will independently screen identified studies for inclusion, and key data will be extracted into a uniform table, facilitating cross-comparison of codes used. Disagreements between the reviewers will be adjudicated by a third reviewer. This protocol has been produced in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocol guidelines.

Ethics and dissemination

As a review of previously published studies, no ethical approval is required. The results of this review will be submitted to a peer-reviewed journal for publication and can be used in future research into respiratory symptoms that uses electronic healthcare databases.
