Moving beyond content validation of nursing diagnoses.

TOPIC: Studies to establish construct and criterion-related validity of nursing diagnoses. PURPOSE: The overwhelming majority of previous studies addressed content validation by nurse experts. This paper describes strategies to move beyond content validation research to construct and criterion-related validation. SOURCES: The range of studies that should be conducted for development of nursing diagnoses are reviewed with examples drawn from the field of psychology. Existing studies on the diagnoses of ineffective breathing pattern, ineffective airway clearance and impaired gas exchange are used as examples. CONCLUSIONS: Many types of studies are needed for each nursing diagnosis. Increased funding and support for nursing diagnosis research will be facilitated by attention to the accuracy of nurses' diagnoses and outcomes of the diagnostic process.

I.v. devices and related infections: causes and complications.

The use of intravenous devices has long been established as a life-saving and important part of total patient management. However, such devices are not without risk and their use is frequently complicated by local or systemic infections and complications. Twenty-five million patients are estimated to enter the NHS annually and receive some form of intravenous therapy by the peripheral route (Campbell, 1998). It behoves all staff who are involved in the management of intravenous devices to base their practice on what is agreed by consensus in the literature as being effective in reducing the risk of hospital-acquired infections. This article draws together such literature and presents recommendations for good practice for the management of intravenous-related devices.

Applying the principles of infection control to wound care.

Human skin in healthy adults is inhospitable organisms. A wound may occur from any accidental or deliberate trauma that breaks the surface of the skin. Once this line of defence is broken there is a risk of infection. All soft tissue injuries, whether chronic, traumatic or surgical, involve the same basic biochemical and cellular processes. This article looks at the risk factors associated with healing of such wounds. The principles of asepsis, wound cleansing agents, choice of dressings and the taking of wound swabs are considered.

Descriptive analysis of eating regulation in obese and nonobese children.

Bite rate, sip rate, and concurrent activities of six 7-yr-old children, three obese and three nonobese, were observed at lunchtime over a six-month period. A procedure for decreasing bite rate, putting eating utensils down between bites, was implemented in a multiple-baseline across-subjects design. Sip rates and concurrent activities were observed to assess behavioral covariations. In addition, bite rate and amount of food completed were computed over six food categories to analyze food preferences. Results indicated the control of bite rate acorss all subjects, with a significant reduction in amount of food consumed. Correlations between the response classes indicated they were at least partially independent. Differences in eating behavior of obese and nonobese subjects were observed for breadstuffs and milk drinking.

Screening infants for neuroblastoma: the parents' perspective.

Health visitors collected urine samples from 6-month-old infants in a feasibility study of infant screening for neuroblastoma. As part of the project's evaluation, a study was conducted of the parents' views and experiences of screening. Parents of the most recently screened infants were contacted: 85 (68% of those contacted) were interviewed. Despite intermittent media coverage and written and verbal information being available, parents' overall knowledge of neuroblastoma screening was poor. Thirteen percent reported that they did not know the purpose of the test. Approximately one-third of parents reported initial anxiety about the test. Where samples were repeated because of unsatisfactory results, this percentage increased to 41% for a first-repeat sample. Parents were willing to make considerable effort to provide samples for screening but worried unnecessarily because the information they were given was either inadequate or in an inappropriate format (ie, verbal instead of written).

Screening infants for neuroblastoma: the parents' perspective in false-positive cases.

The objective of this study was to ascertain the reactions and experiences of parents whose children were defined as false-positive cases in a research program of screening 6-month-old babies for neuroblastoma. Parents of seven of the eight infants falling into this category participated in the study. Parents of five children described themselves as worried/very worried at the positive result, some contemplating the treatment involved and the possibility that their child could die. Parents waited a maximum of 3 days before the clinical investigations took place. The mother of one child was dissatisfied with the handling of the investigations, reporting a lack of information and little opportunity to discuss questions; she was subsequently more anxious about her child. Parents of two children reported lasting "concerns" that they attributed to neuroblastoma screening.

Returning to primary school after treatment for cancer.

Questionnaires were sent to the teachers of 14 children returning to school after treatment for childhood cancer and their 11 siblings. Forty-four control children from the same classes were also selected. Behavioral rating scores (Deasy-Spinetta) showed no differences between cases and siblings or control children in terms of learning disabilities, socialization, and emotional behavior. Teachers reported few problems on the case children's return to school, although many had been anticipated. Most children adapted well, and there were no major changes in behavior or performance. Siblings, too, coped well with the experience. The Royal Victoria Infirmary at Newcastle, where the children were treated, has two community liaison nurses and three social workers. The value of the support that they provide to both families and schools is clearly reflected in the ease with which children reintegrate into their school environment after what can be, for some, a prolonged absence.
