Embedding research in clinical practice: differences in attitudes to research participation among clinicians in a tertiary teaching hospital.

Despite a drive to increase research in healthcare settings, clinician participation in research remains infrequent. This paper describes an online survey comparing attitudes with research participation among clinicians (doctors, nurses and allied health professionals) at an Australian tertiary children's hospital. Differences between professional groups support the existence of different professional cultures surrounding research, suggesting that multiple strategies are required to improve participation in research.

A comparison of doctors', parents' and children's reports of health states and health-related quality of life in children with chronic conditions.

BACKGROUND: Health-related quality of life is an important outcome. Self-report is the gold standard, but in the paediatric setting we often rely on proxy reporting. Our understanding of the differences between self- and proxy reports and the factors that influence them is limited. These differences can impact on treatment choices and the patient-doctor relationship. OBJECTIVE: To evaluate differences between children's, parents' and doctors' perceptions of health states and health-related quality of life in children with chronic illness and explore factors which explain these differences. METHODS: Consecutive families attending eligible clinics at a tertiary paediatric centre were invited to complete the Health Utilities Index (HUI) 23 questionnaire. Percentage agreement and kappas were calculated as a measure of the agreement between pairs. Chi-squared tests or Fisher's exact test, if appropriate, were performed to determine if there was an association between level of agreement and participant variables. RESULTS: Data were collected for 130 parent-doctor pairs, 59 child-parent pairs and 59 child-doctor pairs. Overall health-related quality of life scores did not differ between responders, but there was poorer agreement for subjective domains. Doctor-child agreement was lower than parent-child agreement. Children with a diagnosis of cerebral palsy or chronic neurological condition were more likely to have lower inter-rater agreement for both subjective and objective domains. On the HUI2, agreement was lower for parent-child pairs when the father was the respondent. For child-doctor pairs, an increased frequency of patient-doctor visits and doctors' seniority were predictors of poorer agreement on the HUI3 and HUI2 respectively. CONCLUSIONS: We identified factors associated with level of agreement for self- and proxy reporting on the HUI23. Parent-child agreement was higher than doctor-child agreement. Patients with significant pain or emotional distress and patients with a diagnosis of severe cerebral palsy or chronic neurological conditions were more susceptible to under-reporting of subjective aspects of well-being by doctors and parents and may benefit from formal assessment of health-related quality of life in the clinical setting.

Different priorities: a comparison of parents' and health professionals' perceptions of quality of life in quadriplegic cerebral palsy.

OBJECTIVE: Almost all children with quadriplegic cerebral palsy (CP) have feeding difficulties. Our aim was to identify the major determinants of feeding-related quality of life (QoL) in children with quadriplegic CP from the perspective of parents and to compare findings with the perceptions of health professionals. DESIGN: Qualitative cross-sectional study. METHODS: A trained facilitator conducted four semi-structured focus groups with parents (n = 21) of children with quadriplegic CP attending a multi-disciplinary feeding clinic at a paediatric teaching hospital in Sydney, Australia, between November 2003 and February 2005. All sessions were audio- and video-taped. NVivo software was used to facilitate thematic analysis of the transcribed audiotapes and to compare them with data from focus groups conducted by the same research team with health professional participants. RESULTS: Parental perceptions clustered into the same five themes described by health professionals (parent-child interaction; delivery of health services; the child's emotional well-being; the child's physical well-being, and socialisation), but the content of the subthemes and the values attached differed, for example health professionals valued weight gain, whereas parents valued their child feeling loved. Health professionals did not consider the full range of issues important to families. The differences in priorities for treatment outcomes negatively affected the parent-health professional relationship. CONCLUSIONS: Disparities between parents' and health professionals' perceptions provide useful insight into communication between the two, identify the range of issues important to families, and highlight the parents' expert role in assessing the child's emotional and social well-being. The five themes identified provide a framework for a comprehensive evaluation of the health status of children with quadriplegic CP and feeding difficulties.

Health professionals' perceptions of feeding-related quality of life in children with quadriplegic cerebral palsy.

BACKGROUND: Our aim was to identify the major determinants of feeding-related quality of life (QoL) in children with quadriplegic cerebral palsy (QCP) from the perspective of health professionals to provide a framework for comprehensive clinical evaluation of health status in this group. METHODS: A trained facilitator conducted five semi-structured focus groups during September and November 2003. Participants were recruited through the two paediatric hospitals in Sydney and community-based services, and included general and specialist paediatricians (n = 18), nurses (n = 15) and allied health professionals (n = 13), with an 80% response rate. All sessions were audio- and videotaped. NVIVO software was used to facilitate thematic analysis of the transcribed audiotapes. RESULTS: Responses clustered into five themes: delivery of health services, parent-child interaction, the child's physical and emotional well-being, and social participation. Participants thought the QoL of child and parent was inseparable. Parent-child interaction, delivery of services and physical well-being were the topics which prompted most participant interaction. These findings did not vary across disciplines. CONCLUSIONS: Health professionals identified five domains which provide a framework within which clinicians may comprehensively evaluate the health status of children with QCP and feeding difficulties. These five domains may also be used to inform a new feeding-related QoL instrument for use in this group of patients.

Cellular immune responses of the rat to experimental infection with Dermatophilus congolensis.

The host cell-mediated immune response was examined following experimentally-induced infection of rats with Dermatophilus congolensis, the causal agent of the skin disease dermatophilosis. Mononuclear cells (MC) isolated from Wistar rats 10 days following the induction of a third infection underwent a strong and specific proliferative response, as assessed by a [3H]thymidine incorporation assay, when cultured with various concentrations of inactivated D. congolensis cocci. Using specific monoclonal antibodies in an indirect fluorescent antibody test, this in vitro response was found to be characterised by a large expansion of the W3/25 (T-helper phenotype) population to form 56% of the total. Finally, the primed and stimulated MC were assessed for their ability to produce factors capable of inhibiting macrophage migration. The culture supernatants of D. congolensis-stimulated MC from infected rats caused significant migration inhibition of normal rat peritoneal exudate cells, whilst the supernatants of similarly-stimulated MC from naive rats failed to cause significant inhibition. The results show that a MC subpopulation becomes primed following experimentally-induced infection with D. congolensis and becomes activated after subsequent, in vitro, exposure.
