Multicenter StudyUse of out-of-hospital cardiac arrest registries to assess COVID-19 home mortality.
In most countries, the official statistics for the coronavirus disease 2019 (COVID-19) take account of in-hospital deaths but not those that occur at home. The study's objective was to introduce a methodology to assess COVID-19 home deaths by analysing the French national out-of-hospital cardiac arrest (OHCA) registry (RéAC). ⋯ The ratio of COVID-19 out-of-hospital deaths to in-hospital deaths was 12.4%, and so the national statistics underestimated the death rate.

Multicenter StudyFactors associated with missed assessments in a 2-year longitudinal study of acute respiratory distress syndrome survivors.
To evaluate participant-related variables associated with missing assessment(s) at follow-up visits during a longitudinal research study. ⋯ During the recovery process after hospital discharge, dependencies in physical functioning (e.g. ADLs, IADLs) prior to hospitalization and at hospital discharge were associated with higher odds of missed assessments. Conversely, other indicators of poorer health at baseline were associated with lower odds of missed assessments after the initial post-discharge visit. To reduce missing assessments, longitudinal clinical research studies may benefit from focusing additional resources on participants with dependencies in physical functioning prior to hospitalization and at hospital discharge.

Randomized Controlled Trial Multicenter StudyThe effect of postal questionnaire burden on response rate and answer patterns following admission to intensive care: a randomised controlled trial.
The effects of postal questionnaire burden on return rates and answers given are unclear following treatment on an intensive care unit (ICU). We aimed to establish the effects of different postal questionnaire burdens on return rates and answers given. ⋯ In survivors of intensive care, questionnaire burden had no effect on return rates. However, questionnaire burden affected answers to the same questionnaire (EQ-5D-3 L).

Multicenter StudyMultiple triangulation and collaborative research using qualitative methods to explore decision making in pre-hospital emergency care.
Paramedics make important and increasingly complex decisions at scene about patient care. Patient safety implications of influences on decision making in the pre-hospital setting were previously under-researched. Cutting edge perspectives advocate exploring the whole system rather than individual influences on patient safety. Ethnography (the study of people and cultures) has been acknowledged as a suitable method for identifying health care issues as they occur within the natural context. In this paper we compare multiple methods used in a multi-site, qualitative study that aimed to identify system influences on decision making. ⋯ Combining multiple qualitative methods with a collaborative research approach can facilitate exploration of system influences on patient safety in under-researched settings. The paper highlights empirical issues, strengths and limitations for this approach. Feedback workshops were effective for verifying findings and prioritising areas for future intervention and research.

Multicenter Study Clinical TrialImplementing a complex rehabilitation intervention in a stroke trial: a qualitative process evaluation of AVERT.
The implementation of multidisciplinary stroke rehabilitation interventions is challenging, even when the intervention is evidence-based. Very little is known about the implementation of complex interventions in rehabilitation clinical trials. The aim of study was to better understand how the implementation of a rehabilitation intervention in a clinical trial within acute stroke units is experienced by the staff involved. This qualitative process evaluation was part of a large Phase III stroke rehabilitation trial (AVERT). ⋯ The AVERT stroke rehabilitation trial required commitment to deliver an intervention that needed strong collaboration between nurses and physiotherapists and was different to current care models. This qualitative process evaluation contributes unique insights into factors that may be critical to successful trials teams, and as AVERT was a pragmatic trial, success factors to delivering complex intervention in clinical practice.
