Continuous or intermittent? Which regiment of enteral nutrition is better for acute stroke patients? A systematic review and meta-analysis (2019)
Journal Article
Di Paolo, G., Twomlow, E., Hanna, F., Farmer, A., Lancaster, J., Sim, J., & Roffe, C. (2019). Continuous or intermittent? Which regiment of enteral nutrition is better for acute stroke patients? A systematic review and meta-analysis. https://doi.org/10.32474/OJNBD.2019.03.000163

Background and purpose: Enteral nutrition via nasogastric tube in acute stroke patients with dysphagia is an important determinant of patient outcomes. It is unclear whether intermittent or continuous feeding is more efficacious. The aim of this revi... Read More about Continuous or intermittent?

Should treatment effects be estimated in pilot and feasibility studies? (2019)
Journal Article
Sim. (2019). Should treatment effects be estimated in pilot and feasibility studies?. Pilot and Feasibility Studies, 5, Article 107. https://doi.org/10.1186/s40814-019-0493-7

Background
Feasibility studies and external pilot studies are used increasingly to inform planning decisions related to a definitive randomized controlled trial. These studies can provide information on process measures, such as consent rates, treat... Read More about Should treatment effects be estimated in pilot and feasibility studies?.

Focus group methodology: some ethical challenges (2019)
Journal Article
Sim, J., & Waterfield, J. (2019). Focus group methodology: some ethical challenges. Quality and Quantity, 53, 3003–3022. https://doi.org/10.1007/s11135-019-00914-5

Focus group methodology generates distinct ethical challenges that do not correspond fully to those raised by one-to-one interviews. This paper explores, in both conceptual and practical terms, three key issues: consent; confdentiality and anonymity;... Read More about Focus group methodology: some ethical challenges.

Outcome-adaptive randomization in clinical trials: issues of participant welfare and autonomy (2019)
Journal Article
Sim. (2019). Outcome-adaptive randomization in clinical trials: issues of participant welfare and autonomy. Theoretical Medicine and Bioethics, 40, 83 -101. https://doi.org/10.1007/s11017-019-09481-0

Outcome-adaptive randomization (OAR) has been proposed as a corrective to certain ethical difficulties inherent in the traditional randomized clinical trial (RCT) using fixed-ratio randomization. In particular, it has been suggested that OAR redresse... Read More about Outcome-adaptive randomization in clinical trials: issues of participant welfare and autonomy.

Effect on hospital length of stay of tourniquet use during internal fixation of ankle fracture: randomized controlled trial (2018)
Journal Article
Sim, J., Grocott, N., Majeed, H., & McClelland, D. (2019). Effect on hospital length of stay of tourniquet use during internal fixation of ankle fracture: randomized controlled trial. Journal of Foot and Ankle Surgery, 58(1), 114-118. https://doi.org/10.1053/j.jfas.2018.08.023

Approximately 50% of ankle fractures require internal fixation. A tourniquet is often employed to create a bloodless operative field, but its effect on hospital length of stay (LOS) is unclear. This paper reports a parallel-group observer-blinded ran...

MoTaStim-Foot, a Randomized, Single-Blinded, Mixed-Methods, Feasibility Study Exploring Sensory Stimulation of the Foot and Ankle Early Poststroke (2018)
Presentation / Conference
Aries, A. M., Pomeroy, V. M., Sim, J., Read, S., & Hunter, S. M. (2018, November). MoTaStim-Foot, a Randomized, Single-Blinded, Mixed-Methods, Feasibility Study Exploring Sensory Stimulation of the Foot and Ankle Early Poststroke. Presented at 2018 American Society of Neurorehabilitation Annual Meeting, San Diego, CA. United States

Introduction: It is not known whether increasing somatosensation of the foot could improve walking recovery after stroke. This study was undertaken to investigate the feasibility of conducting a future randomized controlled trial (RCT) to determine w...

In his detailed response to our paper on sample size in qualitative research, Norman Blaikie raises important issues concerning conceptual definitions and taxonomy. In particular, he points out the problems associated with a loose, generic applicatio... Read More about The sample size debate: response to Norman Blaikie.

Can sample size in qualitative research be determined a priori? (2018)
Journal Article
Sim, J., Saunders, B., Waterfield, J., & Kingstone, T. (2018). Can sample size in qualitative research be determined a priori?. International Journal of Social Research Methodology, 5, https://doi.org/10.1080/13645579.2018.1454643

There has been considerable recent interest in methods of determining sample size for qualitative research a priori, rather than through an adaptive approach such as saturation. Extending previous literature in this area, we identify four distinct ap... Read More about Can sample size in qualitative research be determined a priori?.
