Temporal Scanner Thermometry: A New Method of Core Temperature Estimation in ICU Patients

Background and Aims: Temperature measurement is a routine task of patient care, with considerable clinical impact, especially in the ICU. This study was conducted to evaluate the accuracy and variability of the Temporal Artery Thermometer (TAT) in ICU-patients. Therefore, a convenience sample of 57 adult patients, with indwelling pulmonary artery catheters (PAC) in a 40-bed intensive care unit in a university teaching hospital was used. Methods: The study design was a prospective, descriptive comparative analysis. Body temperature was thereby measured simultaneously with the TAT and the Axillary Thermometer (AT), and was compared with the temperature recording of the PAC. The use of vasoactive medication was recorded. Results and conclusions: Mean temperature of all measurements was: PAC: 37.1°C (SD: 0.87), TAT: 37.0°C (SD: 0.68) and axillary thermometer: 36.6°C (SD: 0.94). The measurements of the TAT and the PAC were not significantly different (mean difference: 0.14°C; SD: 0.51; p= 0.33); whereas the measurements of the PAC and the AT differed significantly (mean difference: 0.46°C; SD: 0.39; p< 0.001). Mean difference in PAC versus TAT analyses, between patients with vasopressor therapy (0.12°C; SD: 0.55), and without vasopressor therapy (0.19°C; SD: 0.48) was not statistically significant (p= 0.47). Conclusion: We can conclude that the temporal scanner has a relatively good reliability with an acceptable accuracy and variability in patients with normothermia. The results are comparable to those of the AT, but they do not seem to be sufficient to prove any substantial benefit compared to rectal, oral or bladder thermometry.

Probabilistic Priority Assessment of Nurse Calls

Current nurse call systems are very static. Call buttons are fixed to the wall, and systems do not account for various factors specific to a situation. We have developed a software platform, the ontology-based Nurse Call System (oNCS), which supports the transition to mobile and wireless nurse call buttons and uses an intelligent algorithm to address nurse calls. This algorithm dynamically adapts to the situation at hand by taking the profile information of staff and patients into account by using an ontology. This article describes a probabilistic extension of the oNCS that supports a more sophisticated nurse call algorithm by dynamically assigning priorities to calls based on the risk factors of the patient and the kind of call. The probabilistic oNCS is evaluated through implementation of a prototype and simulations, based on a detailed dataset obtained from 3 nursing departments of Ghent University Hospital. The arrival times of nurses at the location of a call, the workload distribution of calls among nurses, and the assignment of priorities to calls are compared for the oNCS and the current nurse call system. Additionally, the performance of the system and the parameters of the priority assignment algorithm are explored. The execution time of the nurse call algorithm is on average 50.333 ms. Moreover, the probabilistic oNCS significantly improves the assignment of nurses to calls. Calls generally result in a nurse being present more quickly, the workload distribution among the nurses improves, and the priorities and kinds of calls are taken into account.

Pressure ulcers: knowledge and attitude of nurses and nursing assistants in Belgian nursing homes

AIMS

To gain insight into the knowledge and attitudes of nurses and nursing assistants and to study the correlation between knowledge, attitudes and the compliance with the pressure ulcer prevention guidelines provided to residents at risk of pressure ulcers in nursing homes.

BACKGROUND

There is a lack of evidence on knowledge and attitudes of nurses and nursing assistants towards pressure ulcer prevention in nursing homes.

DESIGN

A cross-sectional multi-centre study.

METHODS

A convenience sample of nine Belgian nursing homes, representing 18 wards was chosen in the study. In total, 145 nurses and nursing assistants were included. The compliance with the guidelines was evaluated in 615 residents, and data were collected using validated instruments.

RESULTS

Fully compliant prevention was found in only 6·9% of the residents at risk. The mean knowledge score of the nurses was 29·3 vs. 28·7% for the nursing assistants. The overall attitude score was 74·5%, and attitude scores were significantly different between nurses and nursing assistants. Nurses showed to have a more positive attitude towards pressure ulcer prevention than nursing assistants, respectively 78·3 and 72·3%. A more positive attitude was a significant predictor of pressure ulcer prevention compliance with the guidelines provided to residents at risk of pressure ulcers in nursing homes.

CONCLUSIONS

Knowledge about pressure ulcer prevention of both nurses and nursing assistants in nursing homes was low. Attitudes were a significant predictor of the application of fully compliant prevention in residents at risk.

RELEVANCE TO CLINICAL PRACTICE

Pressure ulcer prevention is an important aspect in daily care for residents at risk in nursing homes. These insights will contribute to evidence-based practice in this area of care and will form the basis for the development of an education strategy for pressure ulcer prevention and management in nursing homes.

Knowledge and attitudes of nurses on pressure ulcer prevention: a cross-sectional multicenter study in Belgian hospitals

BACKGROUND

Evidence-based guidelines for pressure ulcer prevention have been developed and promoted by authoritative organizations. However, nonadherence to these guidelines is frequently reported. Negative attitudes and lack of knowledge may act as barriers to using guidelines in clinical practice.

AIMS

To study the knowledge and attitudes of nurses about pressure ulcer prevention in Belgian hospitals and to explore the correlation between knowledge, attitudes, and the application of adequate prevention.

METHODS

A cross-sectional multicenter study was performed in a random sample of 14 Belgian hospitals, representing 207 wards. Out of that group, 94 wards were randomly selected (2105 patients). Clinical observations were performed to assess the adequacy of pressure ulcer prevention and pressure ulcer prevalence. From each participating ward, a random selection of at least five nurses completed an extensively validated knowledge and attitude instrument. In total, 553 nurses participated. A logistic regression analysis was performed to evaluate the correlation between knowledge, attitudes, and the application of adequate prevention.

RESULTS

Pressure ulcer prevalence (Category I-IV) was 13.5% (284/2105). Approximately 30% (625/2105) of the patients were at risk (Bradenscore <17 and/or presence of pressure ulcer). Only 13.9% (87/625) of these patients received fully adequate prevention whilst in bed and when seated. The mean knowledge and attitude scores were 49.7% and 71.3%, respectively. The application of adequate prevention on a nursing ward was significantly correlated with the attitudes of the nurses (OR = 3.07, p = .05). No independent correlation was found between knowledge and the application of adequate prevention (OR = 0.75, p = .71).

CONCLUSIONS

Knowledge of nurses in Belgian hospitals about the prevention of pressure ulcers is inadequate. The attitudes of nurses toward pressure ulcers are significantly correlated with the application of adequate prevention. No correlation was found between knowledge and the application of adequate prevention.

An ontology-based nurse call management system (oNCS) with probabilistic priority assessment

Background

The current, place-oriented nurse call systems are very static. A patient can only make calls with a button which is fixed to a wall of a room. Moreover, the system does not take into account various factors specific to a situation. In the future, there will be an evolution to a mobile button for each patient so that they can walk around freely and still make calls. The system would become person-oriented and the available context information should be taken into account to assign the correct nurse to a call.

The aim of this research is (1) the design of a software platform that supports the transition to mobile and wireless nurse call buttons in hospitals and residential care and (2) the design of a sophisticated nurse call algorithm. This algorithm dynamically adapts to the situation at hand by taking the profile information of staff members and patients into account. Additionally, the priority of a call probabilistically depends on the risk factors, assigned to a patient.

Methods

The ontology-based Nurse Call System (oNCS) was developed as an extension of a Context-Aware Service Platform. An ontology is used to manage the profile information. Rules implement the novel nurse call algorithm that takes all this information into account. Probabilistic reasoning algorithms are designed to determine the priority of a call based on the risk factors of the patient.

Results

The oNCS system is evaluated through a prototype implementation and simulations, based on a detailed dataset obtained from Ghent University Hospital. The arrival times of nurses at the location of a call, the workload distribution of calls amongst nurses and the assignment of priorities to calls are compared for the oNCS system and the current, place-oriented nurse call system. Additionally, the performance of the system is discussed.

Conclusions

The execution time of the nurse call algorithm is on average 50.333 ms. Moreover, the oNCS system significantly improves the assignment of nurses to calls. Calls generally have a nurse present faster and the workload-distribution amongst the nurses improves.

Involvement of inpatient mental health clients in the practical training and assessment of mental health nursing students: Can it benefit clients and students?

Even though the central position of the client has been recognized in psychiatric nursing education, the client is seldom formally involved in the feedback provided to students during practical training. This research paper focuses on three questions: (1) What conditions support the gathering of meaningful client feedback to enhance the student's learning process and client's wellbeing? (2) Does the use of the practical model for client feedback lead to positive experiences, and if so, under what conditions? (3) To what extent is a client's feedback on the student's work performance, consistent with feedback from the mentor (nurse from the ward), the teacher and the student? Based on a literature review, participatory observation and contacts with experts, a practical model was developed to elicit client feedback. Using this model in two psychiatric inpatient services, clients were actively and formally involved in providing feedback to four, final year psychiatric nursing students. Clients, nurses, teachers and students were interviewed and data were analysed using a qualitative explorative research approach. Analyses revealed that client feedback becomes meaningful in a safe environment created by the psychiatric nurse. Client feedback generates a learning effect for the student and supports the student's recognition of the value and vulnerability of the psychiatric client.

Assessing the adequacy of pressure ulcer prevention in hospitals: a nationwide prevalence survey

INTRODUCTION

The development of a pressure ulcer is an adverse event and is often avoidable if adequate preventive measures are applied. No large-scale data, based on direct patient observations, are available regarding the pressure ulcer preventive interventions used in hospitals.

PURPOSE

The aim of this study was to obtain insight into the adequacy of interventions used to prevent pressure ulcers in Belgian hospitals.

METHODS

A cross-sectional, multi-centre pressure ulcer prevalence study was performed in Belgian hospitals. The methodology used to measure pressure ulcer prevalence was developed by the European Pressure Ulcer Advisory Panel. The data collection instrument includes five categories of data: general data, patient data, risk assessment, skin observation and prevention.

RESULTS

The total sample consisted of 19,968 patients. The overall prevalence of pressure ulcers Category I-IV was 12.1%. Only 10.8% of the patients at risk received fully adequate prevention in bed and while sitting. More than 70% of the patients not at risk received some pressure ulcer prevention while lying or sitting.

CONCLUSION

Generally, there is a limited use of adequate preventive interventions for pressure ulcers in hospitals, which reflects a rather low quality of preventive care. The implementation of pressure ulcer guidelines requires more attention. The pressure ulcer prevention used in practice should be re-evaluated on a regular basis.

Systematic development and validation of a nursing intervention: the case of lifestyle adherence promotion in patients with leg ulcers

AIMS

To describe and discuss of the added value of systematic development and validation of nursing interventions in nursing care.

BACKGROUND

An adherence-promoting intervention for leg ulcer patients was developed in 2008, based on the model of van Meijel. This model requires a systematic development using an analysis of patients' (lived) experiences and professionals' views on (good) care. It employs a cyclical process of trying out, evaluating, revising and reassessing the adapted intervention in patients. The intervention consists of information and counselling sessions carried out by tissue viability nurses and focuses on wearing compression hosiery, practising leg elevation, physical activity and performing leg exercises.

DISCUSSION

Exploring patients' and nurses' perspectives during the development of intervention increases the likelihood that the resultant intervention is both feasible and attuned to patients' needs. Various implementation issues were identified during the developmental process. Validation of the intervention through its use in nursing care aids in refining the intervention and in linking the techniques most successful in effecting behavioural change to theoretical constructs. It contributes to the refinement of concepts of behavioural theories by clarifying the processes underlying the intervention's effectiveness. Direct involvement of the researcher in the validation phase has great added value.

IMPLICATIONS FOR NURSING

Patient involvement in intervention development is essential, as is the researcher's direct involvement in practical situations in which the intervention is tested. Qualitative (evaluation) approaches are recommended.

CONCLUSION

Although the systematic development of nursing interventions is time-consuming, the contribution to the development of nursing practice and nursing science makes it worthwhile.

Malnutrition and nutritional care practices in hospital wards for older people

AIMS

This paper is a report of a study conducted to gain a better insight into the current nutritional care practices in Belgian hospital wards for older people, and to study the association between these practices and the prevalence of malnutrition.

BACKGROUND

In 1999, the Council of Europe assessed nutritional care practices and support in 12 European countries and showed them to be sparse and inconsistent. At the time of research, no studies had described the association between nutritional care practices and malnutrition prevalence in Belgium.

METHODS

In 2007, a cross-sectional survey was carried out in a representative sample of Belgian hospital wards for older people. In total, 2094 patients from 140 wards for older people were included.

RESULTS

The overall prevalence rate of malnutrition in wards for older people was 31.9%. Nutritional care practices such as nutritional screening and assessment, use of a standardized screening instrument and a nutritional protocol were suboptimal. Multilevel analysis revealed that ward characteristics explained for 9.1% whether a patient was malnourished or not. None of the registered nutritional care practices could explain a patient's individual risk.

CONCLUSION

Malnutrition is a frequently occurring problem on hospital wards for older people. Increased consciousness among healthcare professionals and hospital policy makers of the importance of nutritional care will contribute to further improvement in care quality.

The focus of family members' functioning in the acute phase of traumatic coma: part two: Protecting from suffering and protecting what remains to rebuild life

AIMS

The identification and description of the basic psychological process linked with the focus of family members' functioning during the acute phase of traumatic coma.

BACKGROUND

Earlier research learned that hope is a core category in coping with traumatic coma. Hope seems to be the drive to keep family members going and to enable them to fulfil their main task, namely protecting. In the two articles on the focus of family members functioning, this task is defined and the process linked with it is described.

DESIGN

A qualitative approach according to the 'grounded theory' method.

METHOD

Twenty-four in-depth interviews with 22 family members of 16 patients with traumatic coma.

RESULTS

Family members describe the period after the confrontation with traumatic coma as a battle. During this battle, they feel the urge to protect their relative in coma, other family members and themselves. They go through three phases: protecting life, protecting from suffering, protecting what remains to rebuild life. In this article (Part Two) we describe the phase of protecting from suffering and protecting what remains to rebuild life.

CONCLUSIONS

All relatives go through the three phases. Family members who have already overcome previous set-backs get through the process slightly more quickly and experience less extreme emotions.

RELEVANCE TO CLINICAL PRACTICE

Understanding the process of protecting in different phases may help health care professionals to do anything in their power to avoid unnecessary suffering, to ease the pain and to support family members in their task of protecting.

Determination of standard times of nursing activities based on a Nursing Minimum Dataset

AIM

This paper is a report of a study conducted to determine the standard time per nursing activity and the proportion of nursing time covered by the nursing activities of the Belgian Nursing Minimum Dataset compared to the total time of a nurse shift, and to evaluate the correlation between hospital size and standard times of nursing activities.

BACKGROUND

Because of a shrinking workforce and rising workload, nursing managers need tools that help them to allocate their staff to the wards. Such tools should be based on objective time measurements.

METHODS

The study was performed in surgical, internal medicine and elder care wards in an acute hospital care setting. In the first phase, a two-round Delphi-procedure was used to operationalize the definitions of nursing activities. In the second phase, the standard time for each nursing activity was determined, based on data collected over a 6-month period during 2006-2007. A combination of 13,292 work sampling observations by external observers, 3000 recordings of direct time measurement by self-recording and subjective time assessments yielded times that were used to analyse the duration of the nursing activities.

RESULTS

A standard time for 102 nursing activities was established. The coverage of the Belgian Nursing Minimum Dataset in the surgical, internal medicine and elder care wards was 47.5%, 46.4% and 51.0% respectively. The Belgian Nursing Minimum Dataset was found to cover almost 70% of direct and indirect nursing care.

CONCLUSION

Further research is needed to assess the impact on the standard times of nursing activities of inefficient organizational structures and different cultural interpretations of the way an activity is conducted.

Pressure ulcers: development and psychometric evaluation of the attitude towards pressure ulcer prevention instrument (APuP)

BACKGROUND

Pressure ulcers continue to be a significant problem in hospitals, nursing homes and community care settings. Pressure ulcer incidence is widely accepted as an indicator for the quality of care. Negative attitudes towards pressure ulcer prevention may result in suboptimal preventive care. A reliable and valid instrument to assess attitudes towards pressure ulcer prevention is lacking.

AIMS AND OBJECTIVES

Development and psychometric evaluation of the Attitude towards Pressure ulcer Prevention instrument (APuP).

DESIGN

Prospective psychometric instrument validation study.

METHODS

A literature review was performed to design the instrument. Content validity was evaluated by nine European pressure ulcer experts and five experts in psychometric instrument validation in a double Delphi procedure. A convenience sample of 258 nurses and 291 nursing students from Belgium and The Netherlands participated in order to evaluate construct validity and stability reliability of the instrument. The data were collected between February and May 2008.

RESULTS

A factor analysis indicated the construct of a 13 item instrument in a five factor solution: (1) attitude towards personal competency to prevent pressure ulcers (three items); (2) attitude towards the priority of pressure ulcer prevention (three items); (3) attitude towards the impact of pressure ulcers (three items); (4) attitude towards personal responsibility in pressure ulcer prevention (two items); and (5) attitude towards confidence in the effectiveness of prevention (two items). This five factor solution accounted for 61.4% of the variance in responses related to attitudes towards pressure ulcer prevention. All items demonstrated factor loadings over 0.60. The instrument produced similar results during stability testing [ICC=0.88 (95% CI=0.84-0.91, P<0.001)]. For the total instrument, the internal consistency (Cronbachs alpha) was 0.79.

CONCLUSION

The APuP is a psychometrically sound instrument that can be used to effectively assess attitudes towards pressure ulcer prevention in patient care, education, and research. In further research, the association between attitude, knowledge and clinical performance should be explored.

Economic evaluation of pressure ulcer care: a cost minimization analysis of preventive strategies

The purpose of this study was to determine the cost for prevention and treatment of pressure ulcers from a hospital perspective and to identify the least resource-intensive pressure ulcer prevention strategy. Cost analyses were examined from a hospital perspective using direct costs. The study was carried out alongside a prospective cohort study on the incidence and risk factors for pressure ulcers. Two large teaching hospitals in the Netherlands with (partly) opposing approaches in prevention, a technological versus a human approach, were analyzed. The main outcome measures were resource use, costs of preventive measures and treatment, and pressure ulcer incidence in both hospitals. Pressure ulcer prevention through a predominantly technical approach resulted in a similar incidence rate as prevention through a predominantly human approach. However, the technical approach was considerably less expensive.

Pressure ulcer prevention: development and psychometric validation of a knowledge assessment instrument

BACKGROUND

Profound knowledge of pressure ulcers is important to enable good prevention. Validity and reliability of instruments assessing pressure ulcer knowledge are limited evaluated in previous research.

AIMS AND OBJECTIVES

To develop a valid and reliable instrument to assess knowledge of pressure ulcer prevention.

DESIGN

Prospective psychometric instrument validation study.

METHODS

An extensive literature review was performed to develop an instrument to assess knowledge of pressure ulcer prevention. Face and content validity were evaluated in a double Delphi procedure by an expert panel of nine trustees of the European Pressure Ulcer Advisory Panel (EPUAP) who each have extensive experience in pressure ulcer care and research (PhD level). A convenience sample of 608 nurses and nursing students from Belgium and The Netherlands participated to evaluate validity of the multiple-choice test items (item difficulty, discriminating index, quality of the response alternatives), construct validity, internal consistency, and stability of the instrument. The data were collected between February and May 2008.

RESULTS

A 26-item instrument was developed, reflecting 6 themes expressing the most relevant aspects of pressure ulcer prevention. The content validity was excellent (CVI=0.78-1.00). Group scores of nurses with a (theoretically expected) high level of expertise were found to be statistically significantly higher than those of participants with (theoretically expected) less expertise (P<0.001). The item difficulty index of the questions ranged from 0.27 to 0.87, while values for item discrimination ranged from 0.29 to 0.65. The quality of the response alternatives was found to be good. The overall internal consistency reliability (Cronbach's alpha) was 0.77. The 1-week test-retest intraclass correlation coefficient (stability) was 0.88.

CONCLUSION

The instrument demonstrated acceptable psychometric properties and can be applied in both research and practice for evaluating knowledge about pressure ulcer prevention.

Impact of pressure ulcers on quality of life in older patients: a systematic review

OBJECTIVES

To identify the impact of pressure ulcers (PUs) and PU interventions on health-related quality of life (HRQL).

DESIGN

Systematic review and metasynthesis of primary research reporting the impact of PU and PU interventions on HRQL according to direct patient reports. Quality assessment criteria were developed and applied. Data extraction identified findings in the form of direct quotes from patients or questionnaire items and domain results. Combined synthesis of qualitative and quantitative research was performed using content analysis to generate categories and themes from findings. Thirteen electronic databases were searched, and hand searching, cross-referencing, contact with experts, and an online search was undertaken. No language restrictions were applied.

SETTING

Adults with PUs in acute, community, and long-term care settings across Europe, the United States, Asia, and Australia.

PARTICIPANTS

Thirty-one studies including 2,463 participants with PUs were included in the review. Ages ranged from 17 to 96.

RESULTS

The review included 10 qualitative and 21 quantitative studies; 293 findings, 46 categories, and 11 themes emerged. The 11 HRQL themes were physical impact, social impact, psychological effect, PU symptoms, general health, and other impacts of PUs: healthcare professional-client relationships, need for versus effect of interventions, impact on others, financial impact, perceived etiology, and need for knowledge.

CONCLUSION

There is evidence that PUs and PU interventions have a significant impact on HRQL and cause substantial burden to patients.

Dilemmas in measuring and using pressure ulcer prevalence and incidence: an international consensus

Pressure ulcer prevalence and incidence data are increasingly being used as indicators of quality of care and the efficacy of pressure ulcer prevention protocols. In some health care systems, the occurrence of pressure ulcers is also being linked to reimbursement. The wider use of these epidemiological analyses necessitates that all those involved in pressure ulcer care and prevention have a clear understanding of the definitions and implications of prevalence and incidence rates. In addition, an appreciation of the potential difficulties in conducting prevalence and incidence studies and the possible explanations for differences between studies are important. An international group of experts has worked to produce a consensus document that aims to delineate and discuss the important issues involved, and to provide guidance on approaches to conducting and interpreting pressure ulcer prevalence and incidence studies. The group's main findings are summarised in this paper.

[Differenciated function: prospects for the nursing profession in Belgium]

The hospital and medical contexts are undergoing profound change. All professions must follow this evolution, in particular, the nurse profession. The care offer and the care demand are unbalanced: the clinical situations become more complex and the staff is insufficient quantity. The function differentiation can be a solution for the nurse profession. The aim of this study is to evaluate the feasibility of the function differentiation for the nurse profession in Belgium. Based on 364 "patient situations a derived from hospital experiences, required activities and competencies are depicted by more 200 nurses; the complexity of each competency is also evaluated by standardized scales of complexity. A cluster analysis is performed in order to pool all identified competencies. For each department, four groups are identified; each group is relevant on the statistical level but also on the clinical level. The results speak for a function differentiation in a vertical way, but not in a horizontal way between several different departments, in particular for the competencies needed a clinical judgement because these competencies are too specific by department, In conclusion, a function differentiation can be envisaged for the nurse profession in Belgium. Several models from foreign countries set an example for the practical modalities. Several advices in terms of education, lawful framework, interdisciplinary, and collaboration are formulated

Incidence and risk factors for pressure ulcers in the intensive care unit

AIMS

To determine the incidence of pressure ulcers occurring at least 48 hours after admission and risk factors for pressure ulcers grade 2-4 in a long-stay surgical Intensive Care Unit (ICU) population.

BACKGROUND

The incidence of pressure ulcers in intensive care units is larger than in non-intensive environments.

DESIGN

Prospective descriptive research design.

METHODS

Using pressure ulcers grade 2-4 as an outcome measure, a multivariate logistic regression analysis was used to identify the risk factors. Data were obtained on a daily basis in a surgical intensive care unit of the University Hospital Leuven between November 2003-March 2004. A total of 520 long-stay (>or= 24 hours) intensive care patients were included.

RESULTS

Cumulative incidence of pressure ulcers grade 2-4 was 20.1%. The following variables were positively associated with pressure ulcers grade 2-4: history of vascular disease, treatment with Dopamine or Dobutamine, intermittent haemodialysis (IHD) or continuous veno-venous haemofiltration (CVVH), mechanical ventilation. Also preventive measures were statistically positively associated with pressure ulcers grade 2-4: turning, floating heels, alternating mattresses, adequate prevention. The use of sedatives, body temperature above 38.5 degrees C and sitting in chair where negatively associated with pressure ulcers. Pressure ulcers are statistically associated with different risk factors and preventive measures.

CONCLUSION

The identified risk factors are eligible to be included in a new risk assessment scale for patients admitted to intensive care units.

RELEVANCE TO CLINICAL PRACTICE

The novel insights have implications for risk assessment for patients in intensive care units. Patients admitted to intensive care units have other risk factors for pressure ulcers which are eligible to be included in a new risk assessment scale.

How evidence-based is venous leg ulcer care? A survey in community settings

AIM

This paper is a report of a study to describe venous leg ulcer care regarding compression, pain management and lifestyle advice in community settings and to identify factors that predict the provision of lifestyle advice by nurses.

BACKGROUND

Incongruence between evidence and practice in leg ulcer care has been reported. Little is known about predictive factors related to the provision of lifestyle advice.

METHOD

Two focus interviews and a Delphi procedure were used to develop a self-administered questionnaire based on the Graham questionnaire. Nurses employed by community healthcare organizations and independent nurses in private practices participated (n = 789). The data were collected in 2006.

FINDINGS

Compression was applied in 58.7% of patients with venous ulcers. Pain was present in 82.9%. A third of patients with pain received analgesics, but half of these patients (52.1%) took analgesics as prescribed. Half of the nurses (50.8%) gave lifestyle advice related to the leg ulcer. It was mainly instructions about leg elevation (68.3%), promoting physical activity (39.8%) and optimizing nutrition (16.7%) that were provided. Nurses who perceived themselves to have adequate leg ulcer knowledge and skills were 3.75 times more likely to provide lifestyle advice compared with those lacking such knowledge and skills. Nurses who found leg ulcer care not rewarding, rarely successful or difficult gave statistically significantly less lifestyle advice than those who found it rather rewarding, successful and not difficult.

CONCLUSION

Patients with leg ulcers receive less than optimum care and patient education. A particular challenge lies in leg ulcer education programmes and pain management.

Guidelines for the management of venous leg ulcers: a gap analysis

BACKGROUND AND AIM

Since 1998, many leg ulcer practice guidelines were developed. The aim of this paper is to describe the methodological and clinical content quality of those guidelines. Methods PubMed, CINAHL, Cochrane Library and websites known for publishing or collecting clinical practice guidelines were explored from 1998 up to June 2006. Reference lists of all identified guidelines were reviewed for other guidelines to be included. Guidelines were eligible if they were written in English, Dutch, French or German, if the scope was the treatment of venous leg ulcers, if the guideline was systematically developed and if the steps in guideline development were reported clearly. Seven guidelines were critically appraised.

RESULTS

The venous leg ulcer guidelines were clearly based on evidence. The stakeholder involvement varied during the development process. Especially patients' perspectives were often not considered. There was no uniform method used to weigh the evidence. Limited attention was given to pain and lifestyle advice recommendations. A paucity of information on compliance, quality of life, organizational aspects of care and economic evaluation data was given. Most of the guidelines failed to consider the issues of dissemination and implementation. Revisions of the guidelines for leg ulcer treatment were often not available.

CONCLUSION AND IMPLICATIONS FOR FUTURE GUIDELINE DEVELOPERS

It is recommended that leg ulcer guidelines should incorporate a multidisciplinary approach and patient involvement is necessary. Extensive background information and the formulation of the rationale are needed. The development of an implementation guide that addresses the barriers particular to the adoption of guidelines for leg ulcer treatment could support the process of implementation. Recommendations on pain, lifestyle advice, compliance and other quality-of-life issues should be incorporated in guidelines for leg ulcer treatment.

Pressure ulcers: e-learning to improve classification by nurses and nursing students

AIMS AND OBJECTIVES

To detect problems when classifying pressure ulcers and to examine whether an e-learning program is able to increase the classification skills of qualified nurses and nursing students.

BACKGROUND

Both the distinction between pressure ulcer grades and the differentiation between moisture lesions is difficult. Misclassification and incorrect identification of the lesions results in inadequate preventive and therapeutic measures. Education and training are important for spreading evidence-based insights about this topic.

DESIGN

Repeated measure design, consisting of one pretest and three posttests.

METHODS

The experimental intervention consisted of a one-hour session during which the participants independently went over an e-learning program. The control intervention consisted of a one-hour lecture. Both interventions had the same learning contents. A convenience sample of 212 qualified nurses and 214 final-year nursing students was randomly assigned to an experimental-and a control group.

RESULTS

In the pretest, the classification skills were low. After the intervention, these skills improved significantly in both groups. The nursing students achieved better results when using the e-learning program. Among the qualified nurses, there was no difference between the learning methods. Although the classification skills decreased in the posttests, they did not drop under the level of the pretest.

CONCLUSION

The actual classification system does not provide the necessary information about the severity of a pressure ulcer. The differential diagnosis between a moisture lesion was complicated. The classification skills of the qualified nurses and nursing students increased by both learning methods. Repetition remains, however, necessary.

RELEVANCE TO CLINICAL PRACTICE

Both instruction methods are adequate to acquire the knowledge about the differences between moisture lesions and pressure ulcers. E-learning allows studying in one's own time and place, and could therefore be very suitable for repetition of the training. How to organise this training could be a subject for further research.

Adherence to pressure ulcer prevention guidelines in home care: a survey of current practice

AIMS AND OBJECTIVES

To investigate the pressure ulcer prevalence in home nursing patients and to evaluate guideline adherence of measures for the prevention of pressure ulcers and the participation of informal carers in pressure ulcer prevention.

BACKGROUND

Since 2002, the Belgian Guideline for the Prevention of Pressure Ulcers was published on the Internet, but no information was available on guideline adherence in home care.

METHODS

A cross-sectional survey of pressure ulcer prevalence and guideline adherence was performed in a cluster randomized sample of 2779 clients of nine regional nursing departments in Flanders, Belgium. The Belgian Guideline for the Prevention of Pressure Ulcers was the reference standard for the evaluation of the guideline adherence.

RESULTS

There were 744 subjects at risk for developing pressure ulcers. The overall prevalence of pressure ulcers for the total sample population was 6.8%. The age-, sex- and risk-standardized prevalence per regional department varied between 4.9% and 9.1%. Of the 744 subjects at risk, 33 (4.4%) received preventive measures, which were in adherence to the Belgian Guideline for Prevention of Pressure Ulcers, 482 persons (64.8%) were administered measures, which did not adhere to the Belgian Guideline for Prevention of Pressure Ulcers and in 229 subjects (30.8%) at risk for developing pressure ulcers, prevention was lacking. For subjects with at least one pressure ulcer, the proportions were: 4.8% adherence, 76.6% no adherence and 18.6% no prevention. A proportion of 22.2% of the patients at risk and their informal carers were informed and motivated by the home care nurse to participate in the pressure ulcer prevention and their actual participation in the prevention was 21.4% of all risk cases.

CONCLUSIONS

The adherence of nurses and clients to the guideline for pressure ulcer prevention was low. RELEVANCE TO THE CLINICAL PRACTICE: The study demonstrates a detailed evaluation of guideline adherence to pressure ulcer prevention in an individual patient situation, with special attention for materials and measures, which are not adequate and not recommended by the Belgian Guideline for the Prevention of Pressure Ulcers.

How does information influence hope in family members of traumatic coma patients in intensive care unit?

AIMS

To assess the interplay between hope and the information provided by health care professionals.

BACKGROUND

Earlier research learned that hope is crucial for relatives of traumatic coma patients. Also it has been reported that the need for information is extremely important for relatives of critically ill patients.

DESIGN

A qualitative approach according to the 'grounded theory' method with constant comparison was used.

METHOD

We held 24 in-depth interviews with 22 family members of 16 patients with traumatic coma. Data processing and data analysis took place in a cyclic process wherein the induction of themes was alternated by confrontation with new material.

RESULTS

Family members of traumatic coma patients want information that is as accurate as possible, provided by doctors and nurses in an understandable manner and leaving room for hope. At first, family members can do no more than passively absorb the information they receive. After some time, they actively start working with information and learn what to build their hope on. In this way, concrete hope evolves and seems to be strongly determined by information. Information that is more positive than warranted is not appreciated at all. It leads to false hope and once its real nature becomes apparent, to increased distress and loss of trust in the professionals.

CONCLUSION

The process of hope is crucial in coping with traumatic coma and information can facilitate this process.

RELEVANCE TO CLINICAL PRACTICE

If professionals, especially nurses, keep the process in mind that family members go through in handling information, they can not only facilitate this process but also help them to establish realistic hope.

The process and the meaning of hope for family members of traumatic coma patients in intensive care

In this study, the authors examined the process that family members go through when they are confronted with traumatic coma. They conducted 24 semistructured interviews with 22 family members of 16 coma patients and analyzed the data using the constant comparative method as proposed by grounded theory. Hope was the most prominent theme. It can be described as keeping a possible positive outcome in mind in an uncertain situation, knowing that this outcome is unlikely to happen. Hope was found to evolve stepwise up and down, dependent on further events and information: big steps at first, smaller later on. Hope helps family members to keep going and to manage care for the patient and for each other. Family members were found to protect themselves against false or unjustified hope by seeking valid information. They alternate their moments of despair, and in their interactions they respect each other's hope.

The experience of living with a pressure ulcer

This short paper presents a qualitative study, reported in detail elsewhere (Hopkins et al, 2006) that investigated the experience of older people with pressure ulcers. The researchers were surprised to find how significant pain associated with the pressure ulcer was to patients or the impact it had on their lives. All quotes from the participants are taken from Hopkins et al (2006).

Interventions to enhance patient compliance with leg ulcer treatment: a review of the literature

BACKGROUND AND AIMS

Non-compliance with compression therapy and with leg exercises and leg elevation is a common problem, often reported in patients with venous leg ulceration. Studies on compliance-enhancing interventions and the effectiveness of these interventions in patients with venous leg ulceration were reviewed.

METHODS

MEDLINE, Cochrane, Embase and CINAHL were explored up to April 2005. Reference lists, wound care journals and conference proceedings were searched. Experts and manufacturers of compression systems were contacted. Studies were eligible if they included patients with venous or mixed leg ulcers and reported patient compliance outcome. Twenty studies were included.

RESULTS

Most studies describe patient compliance as the extent to which the compression system was worn and/or the extent to which treatment regimen was followed. Self-reporting was the most commonly used method of compliance assessment. There are indications that class III stockings for patients with venous ulcers enhance compliance compared with short stretch compression bandages. No real evidence is found that intermittent pneumatic compression systems improved compliance. There is no well-documented evidence that healthcare system interventions increase compliance. Educational programmes combining cognitive, behavioural and affective components were shown to have a positive effect on leg elevation, but not on compliance with compression therapy.

CONCLUSION

The included studies have a lack of consistency in defining the standard and operationalization of compliance. Patient compliance plays an ancillary role in research. No study has been able to offer an acceptable and well-documented solution to the non-compliance problem.

RELEVANCE TO CLINICAL PRACTICE

Research might focus on the development of comprehensive compliance-enhancing strategies. A stronger commitment of healthcare providers and society is needed to make progress in this area. The scope of nursing must be expanded to also include the problems experienced by patients with leg ulcers and the improvement of patient compliance.

Pressure ulcer prevalence in Europe: a pilot study

RATIONALE AND AIMS

Numerous prevalence studies have been conducted. The problem with these studies is that prevalence proportions cannot be compared with each other, because of differences in performance of each survey. There is no agreed standardized method for determining prevalence proportions. This study aimed to develop and pilot a uniform data collection instrument and methodology to measure the pressure ulcer prevalence and to get some insight into pressure ulcer prevalence across different patient groups in Europe.

METHODS

Pressure ulcer experts from different European countries developed a data collection instrument, which included five categories of data: general data, patient data, risk assessment, skin observation and prevention. A convenience sample of university and general hospitals of Belgium, Italy, Portugal, UK and Sweden participated in the study. In each participating hospital, teams of two trained nurses who collected the data on the wards were established. All patients admitted before midnight on the day of the survey and older than 18 years were included.

RESULTS

The data collection instrument and study procedure of the survey were found to be effective by all participants. 5947 patients were surveyed in 25 hospitals in five European countries. The pressure ulcer prevalence (grade 1-4) was 18.1% and if grade 1 ulcers were excluded, it was 10.5%. The sacrum and heels were the most affected locations. Only 9.7% of the patients in need of prevention received fully adequate preventive care.

CONCLUSION

The methodology is sufficiently robust to measure and compare pressure ulcer prevalence in different countries. The pressure ulcer prevalence was higher than expected and relatively few patients received adequate prevention. This indicates that more attention to prevention is needed in Europe.

Non-blanchable erythema as an indicator for the need for pressure ulcer prevention: a randomized-controlled trial

AIMS AND OBJECTIVES

To evaluate whether postponing preventive measures until non-blanchable erythema appears will actually lead to an increase in incidence of pressure ulcers (grades 2-4) when compared with the standard risk assessment method.

BACKGROUND

To distinguish patients at risk for pressure ulcers from those not at risk, risk assessment scales are recommended. These scales have limited predictive validity. The prevention of further deterioration of non-blanchable erythema (grade 1 pressure ulcer) instead of the standard way of assigning prevention could be a possible new approach.

DESIGN

Randomized-controlled trial.

METHODS

Patients admitted to surgical, internal or geriatric wards (n = 1617) were included. They were randomly assigned to an experimental and a control group. In the experimental group (n = 826), prevention was started when non-blanchable erythema appeared, in the control group (n = 791) when the Braden score was <17 or when non-blanchable erythema appeared. In both groups, patients received identical prevention, either by using a polyethylene-urethane mattress in combination with turning every four hours or by using an alternating pressure air mattress. Pressure points were observed daily and classified according to the four grades of the European Pressure Ulcer Advisory Panel. The Braden scale was scored every three days.

RESULTS

In the experimental group, 16% of patients received preventive measures, in the control group 32%. The pressure ulcer incidence (grades 2-4) was not significantly different between the experimental (6.8%) and control group (6.7%).

CONCLUSION

Significantly fewer patients need preventive measures when prevention is postponed until non-blanchable erythema appears and those patients did not develop more pressure ulcers than patients who received prevention based on the standard risk assessment method.

RELEVANCE TO CLINICAL PRACTICE

Using the appearance of non-blanchable erythema to allocate preventive measures leads to a considerable reduction of patients in need of prevention without resulting in an increase in pressure ulcers.

Expressive language in persons with Prader-Willi syndrome

The aim of the present study was to add to the delineation of the prevalence and nature of language difficulties in Prader-Willi syndrome (PWS). Subjects of this study were 32 Dutch speaking individuals (20 males, 12 females), with chronological ages ranging from 4;6 to 29,5 and total IQ ranging from 40 to 94. Spontaneous speech samples were subjected to a consensus orthographic transcription and analysed by means of TOAST, a Dutch standardized diagnostic instrument to investigate spontaneous language production. It was found that expressive language is usually problematic in PWS. Clearly, different linguistic levels are affected and some levels are more prone to difficulty than others. In general morphosyntax appears to be poor, whereas phonology is fairly good. Difficulties with vocabulary and/or pragmatics may be present as well. Considerable inter-individual variation was found as to the severity of the language problems.

Effectiveness of turning with unequal time intervals on the incidence of pressure ulcer lesions

AIM

This paper reports a study investigating whether repositioning patients lying on a pressure-reducing mattress alternately for 2 hours in a lateral position and 4 hours in a supine position reduces the incidence of pressure ulcers in comparison with repositioning every 4 hours.

BACKGROUND

Repositioning is commonly recognized as an effective preventive measure. Almost no research has been carried out so far on the necessary turning frequencies to prevent pressure ulcer lesions. The pressure is higher in a lateral than in a supine position.

METHOD

A two-arm randomized controlled trial was conducted in 16 Belgian elder care nursing homes. Patients with non-blanchable erythema were randomly assigned to either an experimental or a control group. In the experimental group (n = 122), patients were repositioned alternately 2 hours in a lateral position and 4 hours in a supine position. In the control group (n = 113), patients were repositioned every 4 hours. The sitting protocol was identical in both groups. Pressure areas were observed daily and classified according to the four grades of the European Pressure Ulcer Advisory Panel.

RESULTS

In the experimental group, 16.4% patients developed a pressure ulcer lesion (grade 2-4), while 21.2% did so in the control group. The incidence was not statistically significantly different between the two groups (P = 0.40). The severity (P = 0.65) and location (P = 0.19) of pressure ulcer lesions, and the time to developing them (P = 0.29) were also similar in both groups. No patient developed a pressure ulcer at the hips. A considerable number of patients changed from a lateral to a supine position between the turning intervals.

CONCLUSION

More frequent repositioning on a pressure-reducing mattress does not necessarily lead to fewer pressure ulcer lesions and consequently cannot be considered as a more effective preventive measure.
