“…The risk of ulceration on alternating pressure across these trials ranged between 0 80,81 and 54%. 82 The study by Conine and colleagues 82 studied patients quite dissimilar from those in this trial, namely, people with neurological disease aged between 18 and 55 years. The studies most similar to this one, evaluating some form of alternating pressure mattress in (mainly) older hospital patients, reported pressure ulcer risk on alternating pressure as follows: Hampton 0, 80 Taylor 0 and 9%, 81 Price 2%, 83 Gebhardt 16%, 84 Exton-Smith 16% and 39% 85 and Stapleton 34%.…”

For European countries the cost is £2 per monograph and for the rest of the world £3 per monograph.You can order HTA monographs from our Despatch Agents:-fax (with credit card or official purchase order) -post (with credit card or official purchase order or cheque) -phone during office hours (credit card only).Additionally the HTA website allows you either to pay securely by credit card or to print out your order and then post or fax it. Contact Payment methods Paying by chequeIf you pay by cheque, the cheque must be in pounds sterling, made payable to Direct Mail Works Ltd and drawn on a bank with a UK address. Paying by credit cardThe following cards are accepted by phone, fax, post or via the website ordering pages: Delta, Eurocard, Mastercard, Solo, Switch and Visa. We advise against sending credit card details in a plain email. Paying by official purchase orderYou can post or fax these, but they must be from public bodies (i.e. NHS or universities) within the UK.We cannot at present accept purchase orders from commercial companies or from outside the UK.

HTA on CD is currently free of charge worldwide.The website also provides information about the HTA Programme and lists the membership of the various committees. HTA NHS R&D HTA ProgrammeT he research findings from the NHS R&D Health Technology Assessment (HTA) Programme directly influence key decision-making bodies such as the National Institute for Health and Clinical Excellence (NICE) and the National Screening Committee (NSC) who rely on HTA outputs to help raise standards of care. HTA findings also help to improve the quality of the service in the NHS indirectly in that they form a key component of the 'National Knowledge Service' that is being developed to improve the evidence of clinical practice throughout the NHS.The HTA Programme was set up in 1993. Its role is to ensure that high-quality research information on the costs, effectiveness and broader impact of health technologies is produced in the most efficient way for those who use, manage and provide care in the NHS. 'Health technologies' are broadly defined to include all interventions used to promote health, prevent and treat disease, and improve rehabilitation and long-term care, rather than settings of care.The HTA Programme commissions research only on topics where it has identified key gaps in the evidence needed by the NHS. Suggestions for topics are actively sought from people working in the NHS, the public, service-users groups and professional bodies such as Royal Colleges and NHS Trusts.Research suggestions are carefully considered by panels of independent experts (including service users) whose advice results in a ranked list of recommended research priorities. The HTA Programme then commissions the research team best suited to und...

“…Several of the full articles selected were located in more than one database (duplicates). From 105 unique full articles that were read, a total of 14 studies were included in the final analysis (1,3,11,24–34), all of which were prospective, controlled clinical trials in which a pressure ulcer prevention program was compared with either a control group or another pressure relief program or system and the number of heel ulcers in each intervention group could be determined.…”

This meta-analysis investigated the effectiveness of a pressure-relieving intervention on the incidence of heel pressure ulcers in a variety of settings. Literature searches of Cumulative Index to Nursing and Allied Health Literature, MEDLINE, PubMed, EMBASE and Cochrane databases were conducted for English-language articles that investigated the effect of pressure relief interventions with or without concurrent prevention programs on the number of heel ulcers occurring on adult humans in a controlled clinical design. Full articles were selected from citations based upon consensus between at least two independent reviewers. Methodological quality of each study was assessed using the Jadad and PEDro scales. A quantitative analysis was performed to determine and compare relative risk (RR) between pressure relief programs/devices that were classified according to similarity of interventions. Fourteen studies that involved a total of 1457 subjects were selected from a total of 105 full articles reviewed. Pressure-reducing/relieving surfaces were associated with a significantly lower incidence of heel ulcers compared with standard hospital mattresses (RR = 0.50, 95% CI = 0.26-0.93, P < 0.03). Foam mattresses also significantly reduced the risk of developing heel ulcers. There is evidence to support the use of certain air or foam mattresses/overlays in the prevention of heel pressure ulcers when compared with a standard hospital mattress. There is insufficient research available at this time to determine if heel-protective devices can prevent heel pressure ulcers. These results need to be interpreted with caution given the relatively low number and poor quality of research articles available to date.

“…Maximum and minimum pressure [23,24] Gives no indication of the time varying nature of the pressure Average pressure [25,26] Does not communicate the extent to which pressure is periodically relieved Tissue deformation index [17] A large number of measurements are required and it is complex to calculate Pressure impulse [35,36] Non-intuitive units of measurement (mmHg h 71 ) and provides no clear idea of pressure-free time Skin temperature and humidity [58,59] Both techniques are influenced by several factors within the body and the environment Skin gas tension [42,43] False readings occur, unless the influence of direct pressure on to the electrode is diffused Pressure relief index [37,38] Requires expensive computerized equipment and useful in looking at alternating systems only Laser Doppler fluxmetry [52,53] Arbitrary units of measurement and results cannot be compared from studies using different monitors Clinical trials [5,6] Often influenced by the increased interest and enthusiasm in both staff and patients involved Figure 1. Different methods used for support surface evaluation.…”

“…Therefore, the pressure relieving power of an APAM or APAC cannot be assessed solely from maximum IP. Some investigators have used average IP readings to compare the performance of both static and dynamic support surfaces [25,26]. It is a highly abstracted and dubious value, as it relies on the exact number and placements of sensors.…”

Assessment of patient support surfaces: principle, practice and limitations

Pressure ulcers cause great pain and suffering to patients as well as unnecessary strain on nursing staff. Their treatment is both costly and time consuming. Every effort therefore should be directed towards their prevention. Understanding of the aetiology of pressure ulcers is still incomplete and assessment of devices aimed at prevention is difficult. Over the years, numerous parameters, including interface pressure and transcutaneous blood gas measurements, have been used to evaluate mattresses and cushions. However, the quality of the data gathered is variable and its clinical interpretation remains unsatisfactory. It could be said that the science of evaluation of support surfaces is still at a formative stage, as clinical validation of many of the approaches has yet to be carried out.
