From evidence to influence : dissemination and implementation of scientific knowledge for improved pain research and management

The usual search for explanations and solutions for the research-practice gap tends to analyze ways to communicate evidence-based practice guidelines to practitioners more efficiently and effectively from the end of a scientific pipeline. This examination of the pipeline looks upstream for ways in which the research itself is rendered increasingly irrelevant to the circumstances of practice by the process of vetting the research before it can qualify for inclusion in systematic reviews and the practice guidelines derived from them. It suggests a 'fallacy of the pipeline' implicit in one-way conceptualizations of translation, dissemination and delivery of research to practitioners. Secondly, it identifies a 'fallacy of the empty vessel' implicit in the assumptions underlying common characterizations of the practitioner as a recipient of evidence-based guidelines. Remedies are proposed that put emphasis on participatory approaches and more practice-based production of the research and more attention to external validity in the peer review, funding, publication and systematic reviews of research in producing evidence-based guidelines.

Preliminary studies suggested that pain experienced by infants in the neonatal period may have long-lasting effects on future infant behaviour. The objectives of this study were to find out whether neonatal circumcision altered pain response at 4-month or 6-month vaccination compared with the response in uncircumcised infants, and whether pretreatment of circumcision pain with lidocaine-prilocaine cream (Emla) affects the subsequent vaccination response. We used a prospective cohort design to study 87 infants. The infants formed three groups--uncircumcised infants, and infants who had been randomly assigned Emla or placebo in a previous clinical trial to assess the efficacy of Emla cream as pretreatment for pain in neonatal circumcision. Infants were videotaped during vaccination done at the primary care physician's clinic. Videotapes were scored without knowledge of circumcision or treatment status by a research assistant who had been trained to measure infant facial action, cry duration, and visual analogue scale pain scores. Birth characteristics and infant characteristics at the time of vaccination, including age and temperament scores, did not differ significantly among groups. Multivariate ANOVA revealed a significant group effect (p < 0.001) in difference (vaccination minus baseline) values for percentage facial action, percentage cry time, and visual analogue scale pain scores. Univariate ANOVAs were significant for all outcome measures (p < 0.05): infants circumcised with placebo had higher difference scores than uncircumcised infants for percentage facial action (136.9 vs 77.5%), percentage cry duration (53.8 vs 24.7%), and visual analogue scale pain scores (5.1 vs 3.1 cm). There was a significant linear trend on all outcome measures, showing increasing pain scores from uncircumcised infants, to those circumcised with Emla, to those circumcised with placebo. Circumcised infants showed a stronger pain response to subsequent routine vaccination than uncircumcised infants. Among the circumcised group, preoperative treatment with Emla attenuated the pain response to vaccination. We recommend treatment to prevent neonatal circumcision pain.

A comprehensive review was conducted of the theoretical and empirical work that addresses the preference-match strategy in physician-patient communication. Searches were conducted on Medline, PsychINFO, InFoTrac One File Plus, Sociological Abstracts, and Dissertation Abstracts through 2004. The following keywords were used: patient preferred and received information; patient preferred and actualized treatment decision-making; patient-physician beliefs in shared decision-making; patient-physician match, fit, or concordance; reciprocal relationship or mutuality; doctor-patient affiliation, control, relationship; match/fit between patient and physician in affiliation, control, or relationship. Findings revealed varying degrees of support for the positive effects of matching patients' preferred levels of information, decisional control, and consultative interpersonal behavior. Findings justify not only continued but expanded research efforts in this area that would incorporate recommended changes in research design and implementation. PRACTICE AND RESEARCH IMPLICATIONS: Assessment strategies and match interventions are discussed that, if evidence continues to be supportive, might routinely optimize patient-physician encounters toward more positive outcomes. Methodological guidelines are suggested that can improve future preference-match studies of the patient-physician interaction. Practitioners need to consider adoption of patient-match assessment and intervention strategies in addition to recent exclusive concentrations on patient-centered and shared decision-making approaches.
