The impact of nurses' values on the prevention of pressure ulcers : a Straussian grounded theory study

Samuriwo, Raymond K. January 2011 (has links)
This is a Straussian grounded theory study about the impact of nurses’ values on pressure ulcer prevention. Semi-structured interviews were used to gather data from participants (n=16) who were recruited from the non-acute adult medical wards of 14 hospitals in one NHS Trust and a local university. The participants were asked to talk about their experiences of preventing and managing pressure ulcers and their values were elicited from their accounts. The data were analysed and interpreted with Straussian grounded theory. Nurses were found to work according to the value that they placed on pressure ulcer prevention, as this value influenced the manner in which they prioritised and delivered skin care to their patients. Similar links between nurses’ values and their delivery of care with regards to other aspects of nursing were also identified. The delivery of care to prevent pressure ulcers was found to be subject to clinical priorities and other factors. As a result, the majority of care to maintain skin integrity was delivered by nursing auxiliaries and students because nurses were busy doing other things. Despite this, nurses who place a high value on pressure ulcer prevention appear to be more proactive and determined to deliver care that protects the integrity of their patients’ skin than their peers. This is highlighted by the participants’ accounts of how their prioritisation and delivery of care to prevent pressure ulcers changed when the value that they placed on pressure ulcer prevention increased from low to high. This study also identified the manner in which the value that nurses place on pressure ulcer prevention is formed and evolves. The recommendations that arise from this study are: further testing of this grounded theory in other settings to increase its generalisability and a greater awareness of the impact that the value that nurses place on different aspects of patient care has on their delivery of care to patients, especially with regards to pressure ulcer prevention. Nurse education and training must also take into account some of the factors that help to form and change the value that nurses place on pressure ulcer prevention. Greater attention needs to be paid to the value that nurses place on different aspects of nursing in view of the relationship between nurses’ values and care delivery, if patients are to receive the best possible care.

Úlcera por pressão em idosos institucionalizados: um guia para cuidadores

Sperandio Junior, Carlos Augusto 09 November 2014 (has links)
Úlceras por Pressão (UPP) são áreas de necrose isquêmica em partes moles, causadas por uma pressão prolongada maior que a capilar, com ou sem cisalhamento, relacionada à postura e frequentemente localizada junto a uma proeminência óssea em indivíduos com predisposição clínica. Os fatores extrínsecos pressão, fricção, cisalhamento, umidade e alterações de temperatura são relacionados à engenharia biomédica e decorrem da interação do paciente com a superfície de suporte. Já os intrínsecos, notadamente relacionados às condições de saúde, envolvem o desequilíbrio nutricional e as afecções clínicas, tanto as que diminuem a oxigenação tecidual, como as que implicam no comprometimento da mobilidade. Por ser mais prevalente entre os idosos e por decorrer de múltiplas causas e mecanismos patogênicos, as UPP são classificadas como uma Síndrome Geriátrica. Embora associada principalmente a gerontes, o aporte financeiro empregado no grupo de feridas crônicas, como as UPP, remonta o 3o maior bloco de gastos em saúde no mundo. As UPP são frequentes em pacientes hospitalizados, porém ultrapassam este ambiente, havendo expressiva incidência em residentes de Instituições de Longa Permanência para Idosos (ILPIs). No Brasil, as ILPIs são órgãos sociais, o que gera uma lacuna legal quanto à responsabilidade clínica sobre seus residentes e, consequentemente, sobre as afecções que os acometem, particularmente as UPP. Estas feridas são passíveis de prevenção, destacando-se então o cuidador de idosos, ocupação que vem aumentando em número e importância com o envelhecimento da população e que, no entanto, nem sempre é devidamente instruído. Por meio de uma vasta revisão de literatura, esta dissertação objetivou pontuar os fatores relevantes envolvidos na patogenia das UPP, além das especificidades do indivíduo idoso e do ambiente das ILPIs. Neste contexto, o produto final elaborado foi um guia para prevenção de UPP em ILPIs. / Pressure Ulcers (PU) are areas of localized soft tissue ischemic necrosis caused by prolonged pressure higher than the capillary pressure with or without shear, related to posture which usually occurs over a bony prominence in individual with certain clinical susceptibilities. Extrinsic factors – such as pressure, friction and shear, moisture and temperature changes – are related to biomedical engineering and come from the interaction patient-surface. On the other hand, intrinsic factors are related to health conditions and correspond to nutritional imbalance and/or conditions that decrease tissue oxygenation or impair mobility. Since it features different pathogenic mechanisms and it is more prevalent among the elderly, the PU group is classified as a geriatric syndrome. Worldwide, PU are estimated to be the 3rd largest consumer of resources, plus the social burden and consequences of this condition. PU are quite common in hospitals, however there are several cases among the elderly living in Long-Term Care Facilities (LTCFs). In Brazil, these institutions are supported by social organizations, what produces legal gaps with respect to the residents’ clinical responsibility, and reduces the chances of preventing avoidable diseases as PU. The number of elderly caregivers tends to grow accordingly to the population ageing, creating a window of opportunity for continued education of this group of workers. Through an extensive literature review, this thesis aimed to highlight the relevant findings of the different factors involved in PU pathogenesis as well as to ascertain the particularities of elderly individuals and the specific environment of LTCFs. The final product is a PU prevention guide suitable to use in Brazilian long-term care facilities.
