The Genetic Counseling Video Project (GCVP): models of practice.

Genetic counseling is conceptualized as having both "teaching" and "counseling" functions; however, little is known about how these functions are articulated in routine practice. This study addresses the question by documenting, on videotape, the practices of a national sample of prenatal and cancer genetic counselors (GCs) providing routine pre-test counseling to simulated clients (SCs). One hundred and seventy-seven GCs recruited at two annual conferences of the National Society of Genetic Counselors (NSGC) were randomly assigned to counsel one of six female SCs of varying ethnicity, with or without a spouse, in their specialty. One hundred and fifty-two videotapes were coded with the Roter Interaction Analysis System (RIAS) and both GCs and SCs completed evaluative questionnaires. Two teaching and two counseling patterns of practice emerged from cluster analysis. The teaching patterns included: (1) clinical teaching (31%) characterized by low psychosocial, emotional and facilitative talk, high levels of clinical exchange, and high verbal dominance; and (2) psycho-educational teaching (27%) characterized by high levels of both clinical and psychosocial exchange, low levels of emotional and facilitative talk, and higher verbal dominance. The counseling patterns included: (1) supportive counseling (33%) characterized by low psychosocial and clinical exchange, high levels of emotional and facilitative talk, and low verbal dominance; and (2) psychosocial counseling (9%) with high emotional and facilitative talk, low clinical and high psychosocial exchange, and the lowest verbal dominance. SCs ratings of satisfaction with communication, the counselor's affective demeanor, and the counselor's use of non-verbal skills were highest for the counseling model sessions. Both the teaching and counseling models seem to be represented in routine practice and predict variation in client satisfaction, affective demeanor, and nonverbal effectiveness.

Level of dyspnoea experienced in mechanically ventilated adults with and without saline instillation prior to endotracheal suctioning.

The purpose of this study was to compare the level of dyspnoea with and without the use of 5-cc saline instillation prior to endotracheal suctioning of mechanically ventilated adults. A crossover, quasi-experimental design was used. Seventeen alert, mechanically ventilated adults were asked to rank their level of dyspnoea using the vertical visual analogue scale at specific time intervals surrounding two suctioning events. Saline was randomly assigned to be instilled prior to one of two suctioning episodes. Dyspnoea was ranked immediately after suctioning, and at 10-, 20-, and 30-minute intervals. Data were analyzed using repeated measures analysis of variance with time of measure (immediately after suctioning, 10-, 20-, and 30-minute intervals) and treatment type (with saline versus without saline instillation). The level of dyspnoea based on treatment type (with or without saline) was non-significant. Treatment type by age group interaction was significant (F(1, 15) = 5.41, P = 0.034). The nature of the interaction revealed that older patients (< or = 60 years of age) experienced less dyspnoea without saline prior to suctioning and greater dyspnoea with saline instillation as compared to the younger subjects (<60 years of age). This study documented no beneficial effects of saline. However, it did demonstrate that saline instillation might precipitate a significantly increased level of dyspnoea for up to 10 minutes after suctioning in patients older than 60 years of age. Recommendations based on the results of this study would be to avoid the use of saline instillation prior to suctioning.

Association of mood disturbance and arrhythmia events in patients after cardioverter defibrillator implantation.

BACKGROUND: Life stresses and negative emotions, such as anxiety and depression, are associated with adverse cardiac events, including arrhythmia. Patients undergoing implantation of an automatic internal cardioverter defibrillator provide a unique opportunity to characterize these relationships since all tachyarrhythmia episodes are recorded by the device. OBJECTIVES: The purpose of this study was to examine the association of emotional status after internal cardioverter defibrillator (ICD) implantation and subsequent arrhythmia events. METHODS: An analysis of data obtained in a prospective longitudinal study of responses to the ICD measured mood disturbance (Profile of Mood States; POMS) before implant and at 1, 3, 6, and 9 months postoperatively. Subjects included 144 men and 32 women with a mean age of 60 +/- 13 years and a mean left ventricular ejection fraction (LVEF) of 33 +/- 12%. Arrhythmia events were measured by self-report of shocks and by ICD device interrogation to obtain the number and type (defibrillation, cardioversion, and antitachycardia pacing) of therapies delivered by the ICD. For each time point, POMS scores of subjects who had arrhythmia events were compared with those who did not. For subjects who had ICD shocks, pre-event and post-event POMS scores were also compared. Multiple logistic regression was used at each time point to determine if clinical, demographic and psychological data could predict arrhythmia events. RESULTS: Patients with arrhythmia events had higher POMS scores throughout the 9 months of follow-up. Higher level of mood disturbance (specifically anxiety, fatigue, and confusion) at 1 and 3 months were independent predictors of subsequent arrhythmia events at 3 and 6 months after controlling for LVEF, the presence of coronary artery disease, pre-implant arrhythmia history, and the use of amiodarone and beta-blocking agents. There were no differences in POMS scores before and after ICD shocks, reinforcing the notion that negative emotions were a cause, rather than a consequence, of arrhythmia events. CONCLUSIONS: Mood disturbances, such as anxiety, may increase the risk for arrhythmia events after ICD insertion.

The psychological impact of warts on patients' lives.

Warts were for many years associated with witches and magic rituals. Caused by the human papilloma virus, warts are a common dermatological problem. Warts can have devastating psychological effects on patients. It is vital that patients are offered support and advice as well as treatment.

Forgetting of pictures over a long retention interval in young and older adults.

Young and older adults were presented with pictures for study. Their recognition of the information was tested at five retention intervals: immediately, and 48 hr, 1 week, 2 weeks, and 4 weeks later. The main finding of interest was that picture recognition did not show an age-related decline until the 1-week retention interval.

Test of a nursing intervention to promote adjustment to fibromyalgia.

PURPOSE: This was a test to detect whether a 4-week cognitive behavioral nursing program was effective in increasing adjustment to fibromyalgia (FM) and if the treatment effect would last over time. DESIGN: This was a control and treatment group experimental longitudinal study with outcome measures obtained at pretest and every 3 months for 1 year. SAMPLE: A sample of 71 subjects continued their participation throughout the first year of the study. FINDINGS: Treatment subjects had improved posttreatment adjustment and symptom severity compared to control subjects. When subjects with high pretest psychosocial distress (n = 5) were removed from the analysis, these findings were statistically significant. IMPLICATIONS FOR NURSING PRACTICE: The article can provide direction for developing new comprehensive nursing intervention for patients seen with orthopaedic problems. The intervention schedule may help nurses expand their use of interventions for FM patients. Orthopaedic nurses are especially suited for this challenge.
