Case study methodology in tissue viability. Part 2: A study to determine the levels of knowledge of nurses providing care for patients with leg ulcers in an acute hospital setting.

One of the main components of the clinical governance framework is a comprehensive programme of quality improvement activity that includes the implementation of evidence-based, everyday clinical practice. This paper addresses the challenges surrounding the implementation of one area of evidence-based practice, the management of leg ulcers in an acute hospital trust. The aim of the study was to distinguish the levels of knowledge of nurses providing care for patients with leg ulcers within an acute hospital setting. The design used was that of a collective case study. Each 'case' was a patient with a leg ulcer and the nurses who cared for that patient. They were studied in order to provide insight into the nurses' understanding of leg ulcer management. A number of themes were identified as being common to all the cases. They are: evidence-based practice, nursing skills, quality of life, patient understanding of their ulcer and pain. Each of these themes identified areas of knowledge deficit in the nurses. As part of the implementation of a leg ulcer policy an education programme is being developed to address these deficits.

Case study methodology in tissue viability. Part 1: Methodological considerations.

Case studies are often presented in relation to tissue viability problems. Within hierarchies of evidence, case studies are sometimes seen to be on a par with expert opinion. This paper examines the case study as a research method and seeks to determine its value in tissue viability research. The term 'case study' denotes a general strategy for research where several methods of data collection are used to provide an in-depth analysis of an individual, group or institution. Three types of case study are used in research: intrinsic, instrumental and collective. All case studies utilize data triangulation within their design, that is, the use of a variety of sources of data within a study. It is one of the major strengths of the case study method. Data sources include documentary data sources, observation and interviews. As in any research, validity and reliability are important in case study methodology; in particular, construct validity, internal validity and external validity. Case studies are potentially vulnerable to observer error and observer bias. Examples are given of potential case studies in tissue viability and their strengths and weaknesses. If undertaken prospectively, with clearly defined multiple sources of data collection and a documented chain of evidence, case studies can add breadth to our knowledge and experience of caring for patients with tissue viability problems.

Pressure ulcer prevention--the UK perspective.

Pressure ulcers are a universal problem. Much attention has been given to them in the United Kingdom in recent years. They are seen as a key indicator of the quality of care. Their prevention has become politically, as well as clinically, important.

Monitoring the pressure sore problem in a teaching hospital.

During 1989 and 1990 a series of three prevalence surveys were undertaken in a West Midlands teaching hospital to identify the numbers of patients at risk of developing pressure sores and the actual number of patients with pressure sores, prior to the purchase of pressure relieving equipment. A further survey was undertaken in January 1993 to examine any improvement in pressure sore prevention strategies and in the care of those with established pressure sores. All in-patients were assessed using the Waterlow score. Full details of all pressure sores and any pressure relieving equipment in use was recorded. The findings were compared with those of the first survey in 1989. The prevalence for 1989 was 8.77%, and this had reduced slightly to 7.9% in 1993. There was no significant difference in these figures. However, in 1989 35 patients had 64 pressure sores and in 1993 32 patients had 46 pressure sores. There was a significant reduction in the actual numbers of pressure sores. There was no significant difference in the grades of sores and the sacrum was the most frequent position in both surveys. The survey showed an improvement in the management of established pressure sores. There was little change in the patient populations with respect to the degree of risk of pressure sore development. Using the Waterlow score, the numbers of patients found to be in the no risk, at risk, high risk and very high risk categories remained remarkably stable. These surveys will continue to provide a basis for selecting pressure relieving equipment.(ABSTRACT TRUNCATED AT 250 WORDS)

A prevention and management aid. Evaluation of the Nimbus II mattress.

1. Pressure relief is an important aspect of pressure sore prevention. 2. There are insufficient controlled clinical trials of the many pressure-relieving products available for use. 3. Clinical evaluations of new products can elicit useful information. 4. Evaluation of the Nimbus II Dynamic Flotation System found it to be useful in pressure sore prevention and management.

The size of the pressure-sore problem in a teaching hospital.

A series of three prevalence surveys were undertaken in a teaching hospital (where medical students are taught) in the West Midlands of England to identify the numbers of patients at risk of developing pressure sores and the actual number of patients with pressure sores, prior to the purchase of pressure-relieving equipment. All in-patients were assessed using the Waterlow score. Full details of all pressure sores and any pressure-relieving equipment in use was recorded. There was a mean pressure sore prevalence of 7.32%, the prevalence for each survey being 8.77%, 5.1% and 8.1% respectively. Grades 2 and 3 were the most commonly reported grades and the sacrum was the most frequent position. It was anticipated that there would be a difference in dependency between the patient populations in each of the three surveys. This was not so and, when using the Waterlow score, the numbers of patients found to be at no risk, at risk and at high risk remained remarkably stable. Only those in the very high risk category fluctuated. It is postulated that the difference between the prevalence in the three surveys is related to the difference in the numbers of patients seen to be at very high risk. These surveys have provided a basis for selecting pressure-relieving equipment and baseline information for monitoring the efficacy of the prevention programme.

Measuring the prevalence and incidence of pressure sores.

There is increasing interest in measuring the prevalence and incidence of pressure sores. These terms are often poorly understood and sometimes used interchangeably, although they refer to different forms of data collection. This article seeks to clarify the differences between them.
