Shared mental models of cancer survivorship care.

Quality cancer survivorship care relies on care continuity within the healthcare team. The purpose of this study was to explore the perspectives of healthcare team members regarding cancer survivorship care using the framework of shared mental models. Semi-structured interviews of cancer survivors, primary support individuals, oncology providers, primary care providers and registered nurses were completed. Data were extrapolated to seven primary themes with associated secondary themes. Primary themes included survivor definition and identity, care setting, team member roles, care gaps, survivor needs, barriers to care and facilitators of care. Through these themes, participants emphasised the individuality of the survivorship experience, acknowledged care gaps and described ongoing needs of cancer survivors. Information provision and communication were noted as care facilitators. Through clarification of team member roles, healthcare providers will be equipped to promote cancer survivor transition by focusing on care continuity, communication and collaboration.

Radiological bladder characteristics in VCU for young children with high-grade VUR.

OBJECTIVES: It has been suggested that infants with dilating vesicoureteral reflux (VUR) often have lower urinary tract (LUT) dysfunction. Signs such as high voiding pressure levels, low bladder capacity and dyscoordination at voiding have previously been thought to be indicative of dysfunction. However, these findings have also been recognised in healthy infants and are, thus, not specific to dysfunction in this age group. The urodynamic findings of interest for LUT dysfunction in children with high-grade VUR have been shown to be high bladder capacity with incomplete emptying, and often with overactivity during filling. Because the bladders in children with VUR are often only investigated with voiding cystourethrography (VCUG) and not urodynamics, the question has arisen as to whether some of the urodynamic findings indicating dysfunction can be recognised as radiological signs. The aim of the present study was to evaluate whether cystometric signs of LUT dysfunction in infants with high-grade VUR could be recognised in VCUG. MATERIALS AND METHODS: One hundred and fifteen infants (80 boys) with Grades III-V VUR were included and investigated repeatedly with videocystometry (VCM) at a median age 6, 21 and 39 months. The sign looked for in the VCUG was bladder size (large, normal or small), according to the chosen levels in the bony pelvis. To validate the chosen levels for the different bladder sizes, bladder capacity data from a longitudinal study in healthy children were used. In addition, abnormalities in bladder wall/form and filling of the posterior urethra without voiding, as signs of bladder overactivity and detrusor-sphincter dyscoordination, were evaluated. RESULTS: Bladder size was estimated on VCUG as large, normal or small, according to pelvic landmarks. Large bladder size was mainly seen at the second and third evaluations (64% and 46%), whereas small capacity was mainly seen during the first year (33%). Corresponding cystometric capacities (ml) showed a significant difference between the groups of small, normal and large bladder size. The cystometric capacities of large and small bladder size were also compared with bladder capacity in healthy controls, where large had significantly higher bladder capacity versus age (P = 0.0001) and small had significantly lower (P = 0.011) bladder capacity versus age than in the healthy controls. Bladder shape/wall pathology was mainly seen during the first year (42%), combined with small capacity, and correlated to overactive contractions during filling. Moreover, filling of the posterior urethra without voiding, indicating detrusor/sphincter dyscoordination at voiding, was quite common during the first year (33%), and then successively decreased. CONCLUSIONS: The clinical implication from this study of small children with high-grade VUR was that a large bladder on VCUG was synonymous with a high-capacity bladder. According to earlier studies, this is a sign of LUT dysfunction in this age group and should therefore be an indicator for additional studies of bladder function. Overactive contractions could also be recognised in VCUG, but only at the infant evaluation, which should also be regarded as an indicator of LUT dysfunction. All other bladder VCUG signs mainly seen during early infancy were signs of immature bladder function and not a result of VUR dysfunction.

Comparison of urodynamic and free voiding pattern in infants with dilating reflux.

PURPOSE: We compared simultaneous investigations of free voiding pattern and urodynamic assessment in infants with dilating reflux to obtain further information on previously suspected bladder dysfunction based on abnormal urodynamic findings. MATERIAL AND METHODS: A total of 33 male and 8 female infants with dilating reflux were included in the study. Free voiding pattern was determined by 4-hour voiding observation compared to previously described voiding pattern studies of healthy infants. Simultaneous invasive urodynamic assessments were performed. RESULTS: The patients were grouped according to urodynamic bladder capacity. Half of the male patients had low bladder capacity with high voiding pressure levels (hypercontractile) and the other half had either normal or high capacity bladders. The low capacity group had frequent small voids and a high rate of interrupted voiding, the high capacity group had infrequent voids of high volumes with high residual urine, and the pattern of the normal capacity group differed only from that of healthy infants by an increase in residual urine. All female infants had the typical characteristics of high capacity bladder on free voiding and urodynamic assessments. CONCLUSIONS: Infants with abnormal invasive urodynamic investigations, including those with a small capacity hypercontractile bladder and those with a high capacity bladder, could be identified on free voiding studies, indicating that an abnormal urodynamic pattern represents bladder dysfunction.
