Appendix 6Characteristics of excluded studies (clinical effectiveness review)

StudyReason for exclusion
Allen et al. 1993No clinical outcomes, interface pressure only recorded
Allman 1997Duplicate
Andrews and Balai 1989Not an RCT
Ballard 1997Data recorded were comfort data, no pressure sore outcomes
Barhyte et al. 1995Not an RCT
Bliss 1995Whilst eight surfaces were evaluated in this prospective trial, not all surfaces were in the trial at any one time and so the surfaces were not truly compared with one another contemporaneously. Furthermore, it was possible for patients to be re-randomised back into the study
Bliss and Thomas 1993Duplicate
Bliss et al. 1967Not an RCT; patients were recruited to the trial based on their risk score
Braniff-Matthews and Rhodes 1997Healing and prevention outcome data not separated
Brienza et al. 2001Study of pressure measurement
Chaloner 1999Not an RCT, controlled clinical trial. Duplicate citation with Chaloner and Cave 2000
Chaloner and Cave 2000Not an RCT, randomisation corrupted, authors report that randomisation compromised on the basis of bed availability
Colin et al. 1996No clinical outcomes recorded, only transcutaneous oxygen tension measurements were taken
Conine and Hershler 1991Not an RCT
de Boisblanc et al. 1993Outcome incidence of pneumonia, no pressure ulcer outcomes
Defloor and Grypdonck 2000Does not compare surfaces
Flam et al. 1995Outcome skin temperature and skin moisture level, no pressure ulcer outcomes
Fleischer and Bryant 1997Not an RCT
Geyer et al. 2000Duplicate of Brienza et al. 2001
Grindley and Acres 1996Patients were crossed over between intervention groups at three days. Outcome used was the assessment of patient comfort
Gunningberg et al. 1998Not an RCT. Study of risk calculation rather than prevention
Hampton 1998Not an RCT
Hawkins 1997Not an RCT
Inman et al. 1999Comparison of a bed rental versus a bed purchase strategy – not a comparison of surfaces
Jacksich 1997Not an RCT
Jesurum et al. 1996Not an RCT
Koo et al. 1995Not an RCT, study of interface pressure in healthy volunteers
Marchand and Lidowski 1993Not an RCT
Ooka et al. 1995Quasi-randomised trial design
Phillips 1999N of 1 trial
Regan et al. 1995Reports an audit of pressure sore incidence policy; it is not a prospective RCT
Reynolds and Suarez 1994Not an RCT
Rosenthal et al. 1996Not an RCT
Scott 1995Ongoing study
Scott et al. 1999No clinical outcomes, healthy volunteer study of interface pressures
Scott 2000Not an RCT
Stoneberg et al. 1986Historical control group
Suarez and Reynolds 1995Controlled clinical trial that records only pressure measurements
Thomas 1994Not an RCT
Wells and Geden 1984Interface pressure measurements only recorded
Wild 1991Interface pressure measurements
Zernike 1997Use of egg crate foam as a heel pressure-relieving device, intervention not a bed or mattress. Incidence of pressure ulcer not reported
