Development of a model for case-mix adjustment of pressure ulcer prevalence rates

BACKGROUND: Acute care hospitals participating in the Dutch national pressure ulcer prevalence survey use the results of this survey to compare their outcomes and assess their quality of care regarding pressure ulcer prevention. The development of a model for case-mix adjustment is essential for the use of these prevalence rates as an outcome measure. OBJECTIVE: The development of a valid model for case-mix adjustment to compare the prevalence rates in the acute care hospitals that participated in the 1998 Dutch pressure ulcer prevalence survey, for the purpose of performance comparisons among the hospitals. DESIGN: Cross-sectional design. SUBJECTS: Subjects were patients residing in the 43 acute care hospitals that participated in the national pressure ulcer prevalence survey on May 26, 1998. MEASURES: The study examined the validity of a model for case-mix adjustment of pressure ulcer prevalence rates and compared hospitals to evaluate the impact of adjusted prevalence rates on their performance. RESULTS: A logistic model was developed for case-mix adjustment, using age, malnutrition, incontinence, activity, mobility, sensory perception, friction and shear, and ward specialty. This model was found to have content, construct, and internal validity. Case-mix adjustment influenced the hospitals' performance. CONCLUSION: The data of the national pressure ulcer prevalence survey can be used to develop a valid model for case-mix adjustment. Conclusions about the quality of care were influenced by the use of case-mix adjusted outcomes as a measure of this quality.

Differences in prevalence of pressure ulcers between the Netherlands and Germany--associations between risk, prevention and occurrence of pressure ulcers in hospitals and nursing homes

Aim. This study compares pressure ulcer prevalence and prevention activities in nursing homes and hospitals within two European countries. Background. Over three years stable differences have been found between the Netherlands (NL) and Germany (GER) with higher pressure ulcer rates in the NL. As previous analyses have shown, the differences cannot be entirely explained by differences in the population’s vulnerability to pressure ulcers because they still remain after risk adjustment. Therefore, the differences in prevalence must be caused by other factors. The purpose of this study is to analyse if any potential differences in preventive activities can account for the varying occurrence of pressure ulcers. Method. In both countries, nation-wide surveys were conducted annually using the same standardised questionnaires. Trained nurses examined all consenting patients of the voluntarily participating facilities. This examination included a skin assessment of the entire body. Data regarding risk factors, prevention and details about wounds were then collected. Results. In-patients of 29 German (n = 2531) and 71 Dutch (n = 10 098) nursing homes and 39 German (n = 8515) and 60 Dutch (n = 10 237) hospitals were investigated. The use of pressure-reducing devices was more common in the NL than in GER, but all other interventions were more frequently provided to German risk patients than to their Dutch counterparts. The pressure ulcer prevalence was significantly higher in the Dutch sample. After adjusting for gender, age, Braden Score and prevention, the probability of having a pressure ulcer was 8·1 times higher for Dutch nursing home residents than for German residents. Conclusion. Some of the variance in pressure ulcer prevalence between the two countries can be explained by varying pressure ulcer prevention. However, some remarkable differences still remain unexplained. Relevance to clinical practice. The extent of pressure ulcer prevention, especially repositioning and nutrition intervention provided to patients at risk, is not in accordance with international guidelines.     

The first national pressure ulcer prevalence survey in county council and municipality settings in Sweden

Aim To report data from the first national pressure ulcer prevalence survey in Sweden on prevalence, pressure ulcer categories, locations and preventive interventions for persons at risk for developing pressure ulcers. Methods A cross‐sectional research design was used in a total sample of 35 058 persons in hospitals and nursing homes. The methodology used was that recommended by the European Pressure Ulcer Advisory Panel. Results The prevalence of pressure ulcers was 16.6% in hospitals and 14.5% in nursing homes. Many persons at risk for developing pressure ulcers did not receive a pressure‐reducing mattress (23.3–27.9%) or planned repositioning in bed (50.2–57.5%). Conclusions Despite great effort on the national level to encourage the prevention of pressure ulcers, the prevalence is high. Public reporting and benchmarking are now available, evidence‐based guidelines have been disseminated and national goals have been set. Strategies for implementing practices outlined in the guidelines, meeting goals and changing attitudes must be further developed.     

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.     

The prevalence of pressure ulcers in four paediatric institutions

Aim and objective. Pressure ulcers are a common nursing care issue in hospitals. They are associated with psychological and physical suffering, an increased morbidity and mortality rate and higher overall health care costs. The aim of the current study is to describe the frequency of pressure ulcers in a paediatric care setting and to identify the population at risk, as well as to assess the factors predisposing to the development of pressure ulcers. Design. A point prevalence study. Methods. The study was conducted in four paediatric hospitals in the German‐speaking part of Switzerland and included children from the age of 0–18 years. The method of data collection was a direct systematic inspection and assessment of the skin, taking into account the clinical condition of the patient for risk assessment. A valid risk assessment and data collection instrument was used and, each patient was assessed by a previously instructed rater pair. Results. Of all possible patients, 81% (n = 155) were included. An overall pressure ulcer prevalence of 27·7% (including grade 1) was registered. Thirty‐six patients (84%) had grade 1 ulcers, including many caused by external medical devices. Sixty‐five per cent (n = 100) of all patients were considered at risk (Braden score ≤ 20) of developing a pressure ulcer. Thirty‐five per cent of patients in the risk group were afflicted with one or more pressure ulcers. Conclusions. The prevalence of pressure ulcers in paediatric patients is greater then previously appreciated and the problem requires further exploration. The high percentage of grade 1 pressure ulcers caused by medical devices requires nursing interventions to prevent lesions for these patients. Relevance to clinical practice. The high prevalence rate in paediatric patients is disconcerting and requires further exploration in terms of interventions needed to improve outcomes for this patient group.     

Studying factors related to pressure ulcers prevention: a marginal scale model for modelling heterogeneity among hospitals

Rationale, aims and objectives The purpose of this study was to analyse risk factors associated with the presence of pressure ulcer development in patients referred to several Italian hospitals, taking properly into account the within‐hospital outcome correlation. Methods We analysed data from a prevalence survey coordinated by the European Pressure Ulcer Advisory Panel on 12 000 hospitalized patients in Italy, collecting information on patient's risk, presence of ulcers and prevention measures. The article describes the bases which generalized estimating equations rely on as well as their statistical properties. The article compares different model specifications in the light of background knowledge of the survey data and model assumptions, and discusses the potential for this modelling approach to apply in similar statistical situations. Results In accordance with existing literature, factors associated with pressure ulcers in hospitalized patients were identified as Braden scale, age and assistance‐connected aspects. Between‐hospital variability seemed to be explained by the adopted degree of prevention (use of preventive equipment combined with a repositioning strategy). Conclusions Modelling the covariance matrix or the scale argument of the correlated binary responses (presence/absence of pressure ulcers) by using moment estimators based on generalized estimating equations prevents optimistic inference and provides an important insight into the role of structural differences among hospitals.     

Pressure ulcer: Prevention protocols and prevalence

Aims and objectives The aim of this paper is to analyse the protocols used in German hospitals and nursing homes for the prevention of pressure ulcers with regard to their contents and accordance with the national standard of the Deutsches Netzwerk für Qualitätsentwicklung in der Pflege (DNQP) and the European Pressure Ulcer Advisory Panel (EPUAP) and Royal College of Nursing (RCN) guidelines. Additionally, it is to show the relation between the existence and contents of the protocols of pressure ulcer prevention and pressure ulcer prevalence in the institutions. Methods On a fixed date trained nursing staff gathers data regarding the frequency of pressure ulcers during a prevalence survey. The existence of a pressure ulcer is established by physical examination after the risk assessment with the Braden‐Scale. The patient’s or resident’s informed consent is a precondition for his or her participation in the survey. The protocols are available as hard copies on paper or electronic files. Results Only two out of the 21 protocols developed in‐house are completely concurrent with the expert standard. The EPUAP and RCN guidelines include the aspect of training and further education that is missing in the in‐house protocols and the DNQP expert standard. Evaluation of the data reveals that there is no relation between the availability of protocols and pressure ulcer prevalence. Neither is there any relation between the contents and pressure ulcer prevalence. The institutions currently developing protocols have the lowest prevalence rates. Conclusion It is obvious that, while developing in‐house protocols, the discussion about pressure ulcer prevention has led to a higher problem awareness in nurses and thus to an increased attentiveness in daily nursing practice which then results in improved outcomes. Two years after its publication, the expert standard is still not very well known, therefore this concentrated form of the most up‐to‐date knowledge is not available to all nursing staff as a basis for evidence‐based practice. In addition, the sometimes outdated knowledge of nursing staff impedes the implementation of evidence‐based practice guidelines. A systematic implementation strategy that assists guidelines being applied in practice is therefore required.     

Explaining the national differences in pressure ulcer prevalence between the Netherlands and Germany – adjusted for personal risk factors and institutional quality indicators

Background Pressure ulcers have a known impact on quality of life as well as on morbidity and mortality of the persons affected. Remarkable differences in pressure ulcer prevalence between the Netherlands and Germany have been found during the last 6 years. This study explores to what extent the individual risk of the population and quality indicators of the institutions can explain the variation in national prevalence. Methods Data of a binational multi‐centred cross‐sectional study in 103 hospitals (n = 21 378 patients) and 129 nursing homes (n = 15 579 residents) were analysed using random effects regression models to calculate the differences in national prevalences within the nursing homes and hospitals, adjusted for personal risk for pressure ulcer and quality indicators. Results The prevalence of pressure ulcers among the at‐risk group (Bradenscore ≤20) in nursing homes was 30.8% in the Netherlands and 8.3% in Germany [OR: 4.9 (CI 95%: 4.2–5.7)]. In hospitals, the prevalence among the at‐risk group was 26.1% in the Netherlands and 21.2% in Germany [OR: 1.3 (CI 95%: 1.2–1.5)]. After adjusting for individual risk factors (age, gender, Bradenscore) as well as for quality structures (use of prevention and treatment protocols, experts groups, information leaflets, nurses training, central pressure ulcer statistics and regular updating of protocols), the chance of developing a pressure ulcer was 6.05 times higher (CI 95%: 4.0–9.2) in a Dutch nursing home than in a German nursing home. Within the hospitals, the OR for Dutch patients was 2.03 (CI 95%: 1.4–3.0). Conclusion A remarkable national variation exists in pressure ulcer prevalence and nursing practice. Neither the populations vulnerability for pressure ulcers nor pressure ulcer management as measured in this study could explain this national variation. Therefore, other risk factors should be taken into consideration. Additionally, it is possible that quality indicators are implemented in differing ways with varying levels of effectiveness. Therefore, further research is needed to examine prospectively and in more detail the reality of care within facilities in both countries.     

Epidemiology of haemoglobin disorders in Europe: an overview

OBJECTIVE: As a result of global population movements, haemoglobin disorders (thalassaemias and sickle cell disorders) are increasingly common in the formerly non-indigenous countries of Northern and Western Europe and in the indigenous countries of Southern Europe. This article presents an overview of the changing picture and a method for assessing service needs. METHOD: Data on country of birth or ethnic origin of residents are adjusted to obtain the estimated proportions of residents and births in non-indigenous groups at risk for haemoglobin disorders in European countries. The results are combined with prevalence data in each country of origin to obtain country prevalence estimates. Service indicators (annual tests or other interventions required to ensure equitable delivery of treatment and prevention) are then derived by country. RESULTS: Haemoglobin disorders now occur at comparable frequency throughout Northern, Western and Southern Europe. Annually, there are more affected conceptions in Northern and Western than in Southern Europe, and sickle cell disorders are more common than thalassaemias. There is growing need for health policy-makers to support motivated professionals working to develop optimal patient care, carrier diagnosis, genetic counselling and access to prenatal diagnosis throughout the Region. CONCLUSION: There is a strong case for pan-European collaboration on haemoglobin disorders to share policies, standards and the instruments required to support them. These include methods for needs assessment, service standards, education and information strategies and materials, and methods for evaluating service delivery.     

Antimicrobial use in Finnish acute care hospitals: data from national prevalence survey, 2005

OBJECTIVES: In Finland, use of antimicrobials in ambulatory care is moderate, but some reports suggest that hospital use is higher than in other European countries. We evaluated the amount and type of antimicrobials administered in Finnish acute care hospitals. PATIENTS AND METHODS: We analysed data collected in the national prevalence survey of nosocomial infections (NIs) during February-March 2005 in all tertiary care, all secondary care and 25% of other acute care hospitals. All inpatients present on the study day in acute care wards for adults were included (n=8234). The names and use-days of antimicrobials in Anatomical Therapeutic Class groups J01-J05 were collected on the study day and retrospectively for the previous 6 days. RESULTS: On the study day, 39% of patients had received at least one, 14% at least two and 3% at least three antimicrobials; patients with NI represented 21%, 29% and 45% of these groups, respectively. The prevalence of patients receiving any antimicrobial was 53% in intensive care patients and varied in other specialties from 0% in ophthalmology to 63% in dental and oral surgery. Within a 7 day period, the total use of antibacterial agents (J01) was 64 use-days per 100 patient-days. Cephalosporins were the most frequently used antimicrobials, followed by quinolones and metronidazole. CONCLUSIONS: The prevalence and spectrum of antimicrobial use in Finnish acute care hospitals were high. NI patients contributed markedly to the total usage. The NI survey with a 7 day data collection period provided insights into the use-density of antimicrobials.     

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 α) 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.     

Current European data collection on emergency department presentations with acute recreational drug toxicity: Gaps and national variations

Background. The number of new (novel) psychoactive substances (NPS) available in the illegal market is increasing; however, current monitoring of the drug situation in Europe focuses mainly on classical drugs of abuse, with limited emphasis on clinical presentation in the emergency department (ED). The European Drug Emergencies Network (Euro-DEN) is a European Commission-funded project that aims to improve the knowledge of acute drug toxicity of both classical recreational drugs and NPS. As a baseline for this project, we performed a study to establish which data are currently being collected and reported in Europe on ED presentations with acute toxicity related to NPS and classical drugs of abuse. Methods. We used a three-pronged approach to identify any systematic collection of data on NPS toxicity in Europe by i) performing a literature search, ii) utilising an online survey of the European Monitoring Centre for Drugs and Drug Addiction Re seau Europe en d’Information sur les Drogues et les Toxicomanies national focal points and iii) exploiting the knowledge and resources of the Euro-DEN network members. Results. The literature search revealed 21 papers appropriate for assessment, but only one described a systematic collection of clinical data on NPS. Twenty-seven of thirty countries responded to the online survey. More than half of all the countries (52%) did not perform any registration at all of such data, 37% collected systematic clinical data on NPS at a national level, while 44% collected data on classical drugs. A few examples for good practice of systematic collection of clinical data on ED presentations due to acute toxicity were identified. Conclusion. The systematic collection of data on ED presentation of toxicity related to NPS and classical drugs in Europe is scarce; the existing collection is limited to single centres, single countries, groups of patients or not focused on novel drugs; the collection of data is highly variable between the different countries. Euro-DEN, a European Commission funded project, aims at closing some of these gaps.     

Nurse Managers’ prerequisite for nursing development: a survey on pressure ulcers and contextual factors in hospital organizations

gunningberg l., brudin l. & idvall e. (2010) Journal of Nursing Management  18, 757–766
Nurse Managers’ prerequisite for nursing development: a survey on pressure ulcers and contextual factors in hospital organizations Aim To describe and compare pressure ulcer prevalence in two county councils and concurrently explore Nurse Managers’ perspective of contextual factors in a hospital organization. Background Despite good knowledge about risk factors and prevention of pressure ulcers, the prevalence of pressure ulcers remains high. Nurse Managers’ have a key role in implementing evidence-based practice. Methods The present study included five hospitals in two Swedish county councils: county council A (non-university setting) and county council B (university setting). A pressure ulcer prevalence study was conducted according to the methodology developed by the European Pressure Ulcer Advisory Panel. The Nurse Managers’ answered a (27-item) questionnaire on contextual factors. Results County council B had significantly less pressure ulcers grade (2–4) (7.7%) than county council A (11.3%). The Nurse Managers’ assessed only two out of the 27 general contextual items significantly differently. Some significant differences were observed in ward organization. Conclusions In county council B, the Nurse Managers’ seemed more aware of prevention strategies compared with Nurse Managers’ in county council A. The Nurse Managers’ should take more responsibility to develop the prerequisite for quality improvement in nursing. Implication for nursing management Nursing outcomes (e.g. pressure ulcers) should be incorporated into national quality registries for benchmarking and Nurse Managers’ competence in evidence-based practice and research methodology increased.     

Pressure ulcer care in Spain: nurses' knowledge and clinical practice

AIM: This paper is a report of a study to determine: (a) Spanish nurses' level of knowledge of existing guidelines for pressure ulcer prevention and treatment, (b) the level of implementation of this knowledge in clinical practice and (c) the professional and educational factors that influence knowledge and practice. BACKGROUND: Improvement in pressure ulcer care depends both on the dissemination of knowledge and on its implementation in clinical practice. Studies carried out in several countries have demonstrated gaps in knowledge about recommendations for pressure ulcer care and deficiencies in their implementation. METHODS: A survey was carried out between September 2001 and June 2002, targeting a cluster randomized sample of 2006 Registered Nurses and Licensed Practice Nurses working at hospitals, primary healthcare centres and elder care centres in Andalusia (Spain). RESULTS: The response rate was 36.9% (n = 740). The level of knowledge of prevention interventions was 79.1%, while that of treatment interventions was 75.9%. The levels of implementation in clinical practice were notably lower: 68.1% for prevention, and 65.3% for treatment. Nurses holding a university degree obtained higher scores, and those who had received specific education in pressure ulcer care obtained higher scores both for knowledge and clinical practice. Taking part in research projects also improved knowledge implementation. CONCLUSION: Although most of the recommendations on pressure ulcer care found in guidelines are well known by nurses, there is a group of interventions about which they have insufficient knowledge and low implementation rates.
