Assessment of Pressure Ulcers and Reliability of Risk Assessment Tools

Assessment of Pressure Ulcers and Reliability of Risk Assessment ToolsThe purpose of this assignment, is to identify a affected role, under the complaint of the district nursing team, with a mark 1 compel ulceration, to their sacral atomic total 18a. To begin with, it impart give a apprise overview of the unhurried and their clinical story. Throughout the assignment the patient will be referred to as Mrs A, in order to protect the patients identity and maintain confidentiality, in accordance with the guidelines set out by the Nursing and Midwifery Council (NMC 2008). A brief description of a Grade 1 compress ulcer will be given, along with a description of the steps taken in assessing the infract, victimization The Waterlow photographic plate (1985). This assignment will discuss the literature review that was carried out, along with other methods of research utilize, to gather vital breeding on go against carry on , such as the different classifications of wounds and the different peril judging tools available. This assignment, will hold brief overviews, of some the other commonly employ impel ulcer bump discernment tools, that are put to use by practitioners and how they compare to the Waterlow Scale. This assignment will also seek to toweringlight the grandness of using a combination of clinical astuteness, by palmfully monitoring the patients physical and psychological conditions, alongside the at risk chronicle calculated from the Waterlow Scale, in order to refund holistic kick to the patient.Mrs A is a 84 year old lady who has been referred to the district nurses by her usual Practitioner, as he has concerns regarding her pinch areas . pursual a recent f e real she lost her confidence and is now house bound. She now spends more cadence in her chair as she has become dying(p) when mobilising around the house and in her garden. She has a history of high blood military press and occasional angina for which she currently takes Nicorandil 30mg b.d. as prescribed by her General Practitioner , Nicorandil has been recognised as an aetiological aspect of non healing ulcers and wounds (Watson, 2002), this has to be taken into consideration during the judging and throughout the management of her wound. Mrs A has no history of previous falls or problems with her balance. She has always been a confident and independent lady, with no current issues surrounding temperance or diet. She has always enjoyed a coarse network of friends who visit her regularly. It is recommended by National Institute for Health and Clinical Excellence (NICE) that patients should receive an Initial assessment (within the first 6 hours of inpatient care) and current risk assessments and so referrals of this nature are seen on the day, if it is received if non within 24 hrs. In order to establish Mrs As current risk of developing a compress area, an assessment must take mall. An initial holistic assessment, looking at all cont ributing factors such as mobility, continence and sustenance will fork over a baseline that will identify her level of risk as well as identifying any existing pressure persecute.A pressure ulcer is defined as, a localised injury to the fur and / or underlying tissue usually over a raddled prominence, as a result of pressure, or pressure in combination with shear. A number of contributing, or confounding factors, are also associated with pressure ulcers. fit to the European Pressure Ulcer Advisory Panel (EPUAP 2009).Mrs A is more vulnerable to pressure damage, as her skin has become more fragile and flat with age (NICE 2005). There are risk factors associated to the integrity of the patients skin and also to the patients general health. Skin that is already damaged, has a higher incidence of developing a pressure ulcer, than that of healthy skin. Skin that becomes too dry, or is more moist due to possible incontinence, is also at higher risk of developing a pressure ulcer tha n healthy skin. An elderly persons skin is at increased risk, because it is more fragile and thinner than the skin of a younger person. Boore et al (1987) set the following principles in caring for the skin to pr sluicet pressure damage, skin should be kept clean and dry and not left to remain wet. The skin should also not be left to dry out to prevent any accidental damage . ascribable to Mrs A disbursal more time sitting in her chair, she has become at a higher risk of developing a pressure tippy, as she is less mobile. The reason being It becomes rough for the blood to circulate causing a lack of oxygen and nutrients to the tissue cells. Furthermore, the lymphatic system also begins to suffer and becomes unable, to properly remove waste products. If the pressure continues to increase and is not relieved by equipment or movement. The cells washstand begin to die, leaving an area of dead tissue resulting in pressure damage. Nelson et al (2009) states, pressure ulcers can caus e patients functional limitations, emotional distress, and pain for persons affected. The development of pressure ulcers, in various healthcare settings, is often seen as a reflection of the caliber of care which is being provided (Nakrem 2009). Pressure ulcer prevention is very important in everyday clinical practise, as pressure ulcer treatment is big-ticket(prenominal) and factors such as legal issues book become more important. EPAUP (2009) have recommended strategies, which include frequent repositioning the use of special support surfaces, or providing nutritional support to be included in the prevention.In order to gather evidence ground research, to support my assignment. I undertook a literature review of the Waterlow Scale and Classifications of Grade 1 pressure untougheneds. The databases used were the Culmulative Index to Nursing and Allied Health Literature (CINAHL) and OpenAthens. I used a variety of search basis including pressure sores, Grade 1 classification, Waterlow Scale, and How pressure sore risk assessment tools compare. Throughout the literature review the information was ga in that locationd from sources using a visualize range between the years of 2000 2011, although some references were found from sources of information that are from a much later date. This method of research go outd a plethora of articles and guidelines were collated and analysed. The bank guidelines in wound care were used, to show how we implement theory into practise in the community, using the wound care formulary. There was a vast tally of information available, as pressure area care is such a broad subject. The search criteria had to be narrowed down, in some cases to ensure the information gathered was relevant and not beyond the scope of the assignment. The evidence used throughout this assignment, is based on guidelines and recommendations given by NICE (2001), EPUAP (2001) and articles sourced from The Journal of federation Nursing (JCN). This was the most accurate information and guidance on pressure ulcer classifications and assessment although, some articles may not have been the most recent.The assessment tool used throughout my area of work, is the Waterlow Scale. The Waterlow Scale was developed by Judy Waterlow in 1985, while working as a clinical nurse t individuallyer. It was primitively designed for use by her student and is used to measure a patients risk of developing a pressure sore. It can also be used as a guide, for the ordering of effective pressure relieving equipment. All National Health Service (NHS) trusts have their own pressure ulcer prevention policy, or guidelines and practitioners are expected to use the risk assessment tool, specified in their trusts policy. NICE (2003), guidance states, that all trusts should have a pressure ulcer policy, which should include a pressure ulcer risk assessment tool. However, it reminds practitioners that the use of risk assessment tools, should be thought of a s an aid to the clinical judgement of the practitioner. The use of the Waterlow tool enables, the nurse to assess each patient according to their individual risk of developing pressure sores (Pancorbo-Hidalgo et al 2006). The scale illustrates a risk assessment scoring system and on the reverse side, provides information and guidance on wound assessment, dressings and preventative aids. There is information regarding pressure relieving equipment surrounding, the three levels of risk highlighted on the scale, and also provides guidance, concerning the nursing care given to patients. Although the Waterlow score is used in the community setting, when calculating the risk assessment score, it is vital that the nurse is aware of the difference of opinion in environment the tool was originally developed for.The tool uses a combination of core and outside(a) risk factors that contribute to the development of pressure ulcers. These are used to coif the risk level for an individual patient . The underlying factors include disease, medication, malnourishment, age, dehydration / fluid stance, lack of mobility, incontinence, skin condition and weight. The external factors, which refer to external influences which can cause skin distortion, include pressure, shearing forces, friction, and moisture. There is also a special risk section of the tool, which can be used if the patient is on certain medication or recently had surgery. This contributes to a holistic assessment of a patient and enables the practitioner to provide the most effective care and appropriate pressure relieving equipment. The score is calculated, by counting the scores given in each category, which apply to your patients current condition. Once these have been added up, you will have your at risk score. This will then indicate the steps that wishing to be taken, in order to provide the appropriate level of care to the patient. appellative of a patients risk of developing a pressure sore is often con sidered the most important stage in pressure sore prevention (Davis 1994).During the assessment a skin inspection takes place of the most vulnerable areas of risk, typically these are heels, sacrum and parts of the body, where sheer or friction could take place. Elbows, shoulders, back of orient and toes are also considered to be more vulnerable areas (NICE 2001). When using the Waterlow tool to assess Mrs As pressure risk, I found she had a score of 9. concord to the Waterlow scoring system she is not considered as being at risk as her score is less than 10. As I had set in my assessment, she had a score of 2, for her skin condition due to Grade 1 pressure ulcer to her sacrum. I felt it incumbent, to highlight her as being at risk. A grade 1 pressure ulcer on her sacral area, possibly due to her recent loss of confidence and reduced mobility which has left Mrs A spending more time in her chair.Pressure ulcers are assessed and graded, according to the degree of damage to thetis sue. The National Pressure Ulcer Advisory Panel (NPUAP), classifies pressure ulcers based on the depth of the wound. There are four classifications (Category/Stage I through IV) of pressure damage. In addition to these, two other categories have been defined, unstageable pressure ulcers and inscrutable tissue injury (EPUAP, 2009) Grade 1 pressure damage is defined, as a non-blanchable erythema of intact skin. Indicators can be, discolouration of the skin, warmth, oedema, induration or hardness, peculiarly in people with darker pigmentation (EPUAP, 2003). It is believed by some practitioners, that blanching erythema indicates Grade 1 pressure damage (Hitch 1995) although others suggest that, Grade 1 pressure damage is present, when there is non-blanching erythema (Maklebust and Margolis, 1995 Yarkony et al, 1990). The majority of practitioners, agree that temperature and colour play an important role, in identifying grade 1 pressure ulcers (EPUAP, 1999) and erythema, is a factor i n almost all classifications (Lyder, 1991). The pressure damage usually occurs, over boney prominences (Barton and Barton 1981). The skin in a Grade 1 pressure ulcer, is not broken, but it requires protection and monitoring.At this stage, it will not be cognize how deep the pressure damage is, regularmonitoring and assessment is essential. The pressure ulcer may fade, but if thedamage is deeper than the superficial layers of the skin, this wound could eventuallydevelop into a much deeper pressure ulcer over, the following days or weeks.A Grade 1 pressure ulcer, is classed as a wound and so I have commenced awound care plan and also a pressure area care plan. I will also ensure, Mrs A hasregular pressure area checks in order to prevent the area breaking down. Thepressure area checks will take place weekly until the pressure relieving equipmentarrives, this will then be reduced to 3 monthly checks. Dressings can be applied toa Grade 1 pressure ulcer. They should be simple and offer s ome level of protection.Also, to prevent any further skin damage a film dressing is often used, or ahydrocolloid to protect the wound area (EPAUP, 2009) . These dressings will assist inreducing further friction, or shearing, if these factors are involved. It is consideredthe best way to treat a wound, is to prevent it from ever occurring. Removing theexisting external pressure, reducing any moisture, which can occur if the patient isincontinent and employing pressure relief devices, may contribute to wound healing.Along with adequate nutrition, hydration and addressing any underlying medicalconditions.The advice given to practitioners, on the reverse of the Waterlow tool is to provide a100mm foam cushion, if a patients risk score is above 10. As MrsA has an at risk score of 9, with a Grade 1 pressure sore evident, I feel itappropriate to provide the pressure relieving mattress and cushion to prevent anyfurther pressure damage developing. All individuals, assessed as being vulnerable topressure ulcers should, as a minimum provision, be placed on a high specificationfoam mattress with pressure relieving properties (NICE, 2001). As I am providing acushion and a mattress, it is not felt necessary to apply a dressing at this point.However, the area will need regular monitoring, as at this stage it is unknown howdeep the pressure damage is. If proactive care is given in the prevention andtreatment of pressure ulcers, with the use of risk assessments and providingpressure relieving resources, the pressure area may resolve. Pressure ulcers can becostly for the NHS, debilitating and painful for the patient. With basic and effectivenursing care offered to the patients, this can often be the key to success. happiness (2000) suggests that the majority of Grade I ulcers heal, or resolve withoutbreaking down if pressure relief is put into place immediately. However, experiencesin a clinical settings supports observations, that non-blanching erythema can oftenresult in irre versible damage (James, 1998 Dailey, 1992).McGough (1999) during a literature search, highlighted 40 pressure ulcer riskassessment tools, but not all have be considered suitable, or reliable for all clinicalenvironments. As there are many different patient groups this often results in a widespectrum of different patient needs. The three most commonly used tools in the United Kingdom (U.K.) are, The Norton scale, The Braden Scale and The Waterlow Scale.The first pressure ulcer risk assessment tool was the Norton scale. It was devised by Doreen Norton in 1962. The tool was used for estimating a patients risk for developing pressure ulcers by giving the patient a evaluate from 1 to 4 on five different factors. A patients with a score of 14 or more, was identified as being at high risk. Initially, this tool was aimed at elderly patients and there is little evidence from research gathered over the years, to support its use outside of an elderly care setting. Due to increased research ov er the years, concerning the identification and risk of developing pressure ulcers, a modified version of the Norton scale was created in 1987.The Braden Scale was created in the mid(prenominal) 1980s, in America and based on a conceptual schema of aetiological factors. Tissue tolerance and pressure where identified, as being significant factors in pressure ulcer development. However, the validity of the Braden Scale is not considered to be high in all clinical areas (Capobianco and McDonald, 1996). However, EPAUP (2003) state The BradenRisk Assessment Scale is considered by many, to be the most valid and reliablescoring system for a wide age range of patients.The Waterlow Scale, first devised in 1987, identifies more risk factors than the Braden and the Norton Scale. However, even though it is used widely across the U.K., it has still be criticised for its ability to over predict risk and ultimately result in the misuse of resources (Edwards 1995 McGough, 1999).Although there are v arious tools, which have been developed to identify a patients individual risk, of developing pressure sores. The majority of scales have been developed, based on ad hoc opinions, of the importance of possible risk factors, according to the Effective Healthcare Bulletins (EHCB, 1995). Franks et al, 2003 Nixon and Mc Gough, 2001, challenged the predictive validity of these tools, suggesting they may over predict the risk, cause expensive cost implications, as preventative equipment is put in place, when it may not always be necessary. Or they may under predict risk, so a patient maybe assessed as not being at high risk, develops a pressure ulcer. Although the Waterlow scoring system, now includes more objective measurements such as Body potful Index (BMI) and weight loss after a recent update. It is still unknown, due to no published information, whether the reliability of the waterlow tool, has improved since the changes that took place. It has been recognised, as a fundamental fla w of these tools and due to this clinical judgement, must always be taken into consideration alongside the results that have been measure, from the use of the risk assessment. This is clearly recognised by NICE, as they advise their use as an aide-mmoire (2001). The aim of Pressure ulcer risk assessment tools, is to measure and quantify pressure ulcer risk. To determine the quality of these measurements the evaluation of validity and reliability would usually take place. The validity and reliability limitations, of pressure ulcer risk tools are widely acknowledged. To overcome these problems, the dissolver that is recommended is to combine the scores of pressure ulcer risk tools, with clinical judgment (EPAUP 2009). This recommendation, which is often seen in the literature, unfortunately is inconsistent as Papanikolaou et al (2007) states If pressure ulcer risk assessment tools have such limitations, what contribution can they make to our confidence in clinical judgment, other tha n prompting us about the items, which should be considered when making such judgments?. Investigations of the validity and reliability, of pressure ulcer risk tools are important, in evaluating the quality, but they are not sufficient to judge their clinical value. In the research of pressure ulcer tools, there have been few attempts made to compare, the different pressure ulcer risk assessment strategies. Referring to literature until 2003, Pancorbo Hidalgo et al (2006) identified three studies, investigating the Norton scale compared to clinical judgment and the impact on pressure ulcer incidence. From these studies, it was concluded that there was no evidence, that the risk of pressure ulcer incidence was reduced by the use of the risk assessment tools. The Cochrane review (2008), set out to determine, whether the use of pressure ulcer risk assessment , in all health care settings , reduced the incidence of pressure ulcers. As no studies met the criteria, the authors have been u nable to answer the review question. At present there is only weak evidence to support the validity, of pressure ulcer risk assessment scale tools and obtained scores contain varying amounts of measurement error.To improve our clinical practise, it is suggested that although tools such as theWaterlow Scale are used to distinguish a patients pressure ulcer risk, otherinvestigations and tests, may need to be carried out to ensure a effectiveassessment is taking place. Practitioners may consider, various blood tests and morein depth history taking, including previous pressure damage and medications. Patientsmodus vivendi and diet should also be taken into consideration and where appropriate, anutritional assessment should be done if recent weight loss, or reduced propensity isevident. Nutritional assessment and screening tools are being used more readily and appear to be becoming more relevant in managing patients who are at risk of or have a pressure ulcer. The assessment tools shoul d be reliable and valid, and as discussed previously with other risk assessment tools they should not replace clinical judgement. However, the use of nutritional assessment tools can help to bring the nutritional status of the patient to the attention of the practitioner, they should then consider nutrition when assessing the patients vulnerability to pressure ulcer development. The nutritional status of the patient should be updated and re-assessed at regular intervals following a assessment plan which is individual to the patient and includes an evaluation date. The condition of the individual will then allow the practitioner to decide how frequent the assessments will occur. The EPUAP (2003) recommends that as a minimum, assessment of nutritional status should include regular weighing of patients, skin assessment, documentation of food and fluid intake.As Mrs A currently has a balanced diet, it is not felt necessary to undertake, anutritional assessment at this point. Her weight can be updated on each review visit,to assess any weight loss during each visit. If there is any deterioration in hercondition, an assessment can be done when required. Continence should also betaken into consideration and where necessary a continence assessment should takeplace. Incontinence and pressure ulcers are common and often occur together.Patients who are incontinent are generally more possible to have difficulties with theirmobility and elderly, both of which have a strong association with the developmentof pressure ulcers (Lyder, 2003).The education of staff, surrounding pressure ulcer management and prevention, isalso very important. NICE (2001) suggest, that all health care professionals, shouldreceive relevant training and education, in pressure ulcer risk assessment andprevention. The information, skills and knowledge, gained from these trainingsessions, should then be cascaded down, to other members of the team. Thetraining and education sessions, which are provided by the trust, are expected tocover a number of topics. These should include, risk factors for pressure ulcerdevelopment, skin assessment, and the alternative of pressure equipment. Staff arealso updated on policies, guidelines and the latest patient educational information(NICE 2001).Education of the patient, carers and family, is essential in order to achieve optimumpressure area care. Mrs A is encouraged to mobilise regularly, in order to relievethe pressure as a Grade 1 pressure sore has been identified, she is at a significantrisk of developing a more severe ulcer. Interventions to prevent deterioration, arecrucial at this point. It is thought, that this could prevent the pressure sore fromdeveloping into a Grade 2 or worse. NICE (2001) have suggested, that individualsvulnerable to or at elevated risk of developing pressure ulcers, who are able andwilling, should be informed and educated about the risk assessment and resultingprevention strategies. NICE have devised a booklet for patients and relatives, calledPressure Ulcers Prevention and discourse (NICE Clinical Guidance 29), which givesinformation and guidance on the treatment of pressure ulcers. It encourages patientsto check their skin and change their position regularly. As a part of inviolable practise,this booklet is given to Mrs A at the time of assessment, in order for her todevelop some understanding of her pressure sore. This booklet is also given to thecare givers or relatives so they can also gain understanding, regarding the care andprevention, of her pressure ulcer. An essential part of nursing documentation, is careplanning. It demonstrates the care, that the individual patient requires and can beused to include patients and carers or relatives in the patients care. Involvement ofthe patient and their relative, or carer is advisable, as this could be invaluable, tothe nurse planning the patients care. The National Health Service modernisationAgency (NHSMA 2005) states clearly that per son centred care is vital and that care planning involves negotiation, discussion and shared decision making, between the nurse and the patient.There were a number of improvements that I feel could have been made to the holistic care of Mrs A. I feel that one of the fundamental factors that needed to be considered , were the social needs of the patient. As I feel they are a large contributing factor, towards why the patient may have developed her pressure sore. The patient was previously known to be a very sociable lady, who gradually lost her confidence, resulting in her not leaving the house. There are various schemes and services available, which are provided by the local council or volunteer services, to enable the elderly or people unable to get around. For example, an option which could of been suggested to Mrs A are services such as Ring and Ride, or Werneth Communicare. Using these services or being involved in these types of schemes, may have empowered Mrs A to leave the house on a more regular basis. This would enable her to build up the confidence, she lost following her fall. This would have also lead to positive impact on the patients psychological care, as Mrs A would have been able to overcome her fears of leaving the house, enabling her to see friends and gain communications lost. As previously mentioned in this assignment, although Mrs A had a score of 9, which is not considered an at risk score. I still felt it necessary to act on this score, even though the wound was a not considered to be critical. If it is felt the patient is at a higher risk than that shown on the assessment tool, the practitioner should use their clinical judgement, to make crucial care decisions. It should also be considered, by the practitioner that risk assessment tools such as The Waterlow scale, may not have been developed, for their area of practise. Throughout the duration of Mrs As wound healing process, a holistic assessment of her pressure areas and general h ealth assessment were carried and all relevant factors, were taken into consideration. The assessment tool used to assess her pressure areas, is the most common tool used currently in practise and the tool recommended by the Trust.To conclude, there is evidence to prove that pressure ulcer risk assessment tools are useful, when used as a guide for the procurement of equipment. However, they cannot be relied upon solely to provide holistic care to a patient. It has been highlighted, that to ensure a holistic assessment of patients, it is necessary to complete a variety of assessments, to create a complete picture. Although The Waterlow scale covers a number of factors that need to be considered, throughout the assessment, it has become evident that the at risk score, can often be over or under scored depending on the practitioner. Clinical judgement has proved to be, a very important aspect of pressure ulcer prevention and treatment. The education of the patient, carer and relatives has also been highlighted, as an important aspect of care. Empowering the patient with information regarding their illness, may decrease the healing time and help prevent has further issues.
