Inter-rater reliability of the EPUAP pressure ulcer classification system using photographs

Background. Many classification systems for grading pressure ulcers are discussed in the literature. Correct identification and classification of a pressure ulcer is important for accurate reporting of the magnitude of the problem, and for timely prevention. The reliability of pressure ulcer classification systems has rarely been tested. Aims and objectives. The purpose of this paper is to examine the inter-rater reliability of classifying pressure ulcers according to the European Pressure Ulcer Advisory Panel classification system when using pressure ulcer photographs.Design. Survey was among pressure ulcer experts.Methods. Fifty-six photographs were presented to 44 pressure ulcer experts. The experts classified the lesions as normal skin, blanchable erythema, pressure ulcer (four grades) or incontinence lesion. Inter-rater reliability was calculated.Results. The multirater-Kappa for the entire group of experts was 0.80 (P < 0.001).Various groups of experts obtained comparable results. Differences in classifications are mainly limited to 1 degree of difference. Incontinence lesions are most often confused with grade 2 (blisters) and grade 3 pressure ulcers (superficial pressure ulcers).Conclusions. The inter-rater reliability of the European Pressure Ulcer Advisory Panel classification appears to be good for the assessment of photographs by experts. The difference between an incontinence lesion and a blister or a superficial pressure ulcer does not always seem clear.Relevance to clinical practice. The ability to determine correctly whether a lesion is a pressure ulcer lesion is important to assess the effectiveness of preventive measures. In addition, the ability to make a correct distinction between pressure ulcers and incontinence lesions is important as they require different preventive measures. A faulty classification leads to mistaken measures and negative results. Photographs can be used as a practice instrument to learn to discern pressure ulcers from incontinence lesions and to get to know the different grades of pressure ulcers. The Pressure Ulcer Classification software package has been developed to facilitate learning

An investigation of pressure ulcer risk, comfort and pain in medical imaging

In this study, we investigated the interface pressure of healthy volunteers on medical imaging (MI) table surfaces to determine the risks of developing pressure ulcers (PU). We also investigated volunteers’ perception of pain and comfort while lying on the MI table surfaces. Evidence from this study will enhance the understanding of factors contributing to PU formation and help improve service delivery to patients undergoing MI procedures

Pressure RElieving Support SUrfaces: a Randomised Evaluation 2 (PRESSURE 2): study protocol for a randomised controlled trial

Background Pressure ulcers represent a major burden to patients, carers and the healthcare system, affecting approximately 1 in 17 hospital and 1 in 20 community patients. They impact greatly on an individual’s functional status and health-related quality of life. The mainstay of pressure ulcer prevention practice is the provision of pressure redistribution support surfaces and patient repositioning. The aim of the PRESSURE 2 study is to compare the two main mattress types utilised within the NHS: high-specification foam and alternating pressure mattresses, in the prevention of pressure ulcers. Methods/Design PRESSURE 2 is a multicentre, open-label, randomised, double triangular, group sequential, parallel group trial. A maximum of 2954 ‘high-risk’ patients with evidence of acute illness will be randomised on a 1:1 basis to receive either a high-specification foam mattress or alternating-pressure mattress in conjunction with an electric profiling bed frame. The primary objective of the trial is to compare mattresses in terms of the time to developing a new Category 2 or above pressure ulcer by 30 days post end of treatment phase. Secondary endpoints include time to developing new Category 1 and 3 or above pressure ulcers, time to healing of pre-existing Category 2 pressure ulcers, health-related quality of life, cost-effectiveness, incidence of mattress change and safety. Validation objectives are to determine the responsiveness of the Pressure Ulcer Quality of Life-Prevention instrument and the feasibility of having a blinded endpoint assessment using photography. The trial will have a maximum of three planned analyses with unequally spaced reviews at event-driven coherent cut-points. The futility boundaries are constructed as non-binding to allow a decision for stopping early to be overruled by the Data Monitoring and Ethics Committee. Discussion The double triangular, group sequential design of the PRESSURE 2 trial will provide an efficient design through the possibility of early stopping for demonstrating either superiority, inferiority of mattresses or futility of the trial. The trial optimises the potential for producing robust clinical evidence on the effectiveness of two commonly used mattresses in clinical practice earlier than in a conventional design

Prevalência e características das feridas em pessoas idosas residentes na comunidade

RESUMO Objetivo Descrever o perfil e as características de idosos com restrição de mobilidade, residentes na comunidade e com presença de lesões de pele. Método Estudo exploratório e descritivo, parte do Estudo SABE – Saúde Bem-estar e Envelhecimento que avaliou a presença de lesões de pele em uma amostra probabilística de idosos residentes no município de São Paulo segundo aspectos sociodemográficos, biomarcadores sanguíneos, condições de saúde e utilização de serviços. A análise utilizou o teste de qui-quadrado com correção de Rao-Scott para amostras complexas com nível de significância de 5%. Resultados No ano de 2010, 20,7% dos idosos com restrição de mobilidade apresentavam lesões na pele em decorrência desse problema. Os locais mais frequentes foram região sacral para ambos os sexos, escapular para mulheres e trocanteriana para homens. Idade mais avançada, multimorbidade e comprometimento funcional foram mais prevalentes entre os idosos com feridas, assim como a maior frequência de cuidado requerido. A disfuncionalidade familiar mostrou-se associada à maior sobrecarga do cuidador que pode refletir na qualidade do cuidado prestado. Observou-se que esses idosos que são prioritários para a atenção domiciliar não a recebem adequadamente. Conclusão A prevalência de lesões de pele em idosos com restrição de mobilidade na comunidade é baixa, no entanto requerem atenção diferenciada e essa não está sendo adequadamente oferecida. A reorganização das políticas e serviços assistenciais mostra-se essencial
