Mobile health apps are proliferating, but they fail to deliver on a key patient and caregiver requirement - the ability to collaborate using key phone features while leveraging existing web services. Typically, mobile health apps are for single use, proprietary, and deliver closed-world solutions. By making use of web services, both open and proprietary, mobile health apps can be created to support the caregiver network in the community. The full value of telehealth will only be achieved when the spectrum of trusted health care services (preventive, promotion, curative, and rehabilitative) is delivered to the collaborating network of caregivers.

The Rib Vertebra Angle Difference and its Measurement in 3D for the evaluation of early onset scoliosis.
The Rib Vertebra Angle Difference (RVAD) as defined by Mehta (1972) is used to predict the progression of early onset scoliosis. No clear physical significance has been established for this measurement. The purpose of this study was to evaluate the RVAD along the thoracic spine and the equivalent measurement on 3D reconstructions of the spine and rib cage of early onset scoliosis patients in order to determine their relationship with the geometry of the chest wall and evolution along the spine. ⋯ Results indicated that RVAD 3D provides additional information to Mehta's RVAD on the torsional nature of the deformity. Considering the importance of clinical indices to assess the progression of early onset scoliosis, this study raises some questions on looking solely at the RVAD measured on radiographs at the apical vertebra of Phase I patients and suggests considering also levels above the apex of the scoliotic curve and 3D measurements. Further investigation is required to fully understand the 3D nature of the spine and rib cage deformities.

Clinical TrialThe effect of pressure pad location of spinal orthosis on the treatment of adolescent idiopathic scoliosis (AIS).
Patient with moderate AIS is usually prescribed with spinal orthosis aiming to mechanically support and prevent the spine from further deterioration. In the conventional fitting method, pre-brace X-ray is the main reference, thus, the pressure pad of spinal orthosis may not be accurately located to the strategic areas because the spinal deformities could change 3-dimensionally once pressure pad is applied. A high correlation (r > 0.98) between Cobb's angle and spinous process angle (SPA) was found in the recent studies. ⋯ The assessments of in-brace X-rays showed that the mean Cobb's angle of group A decreased from 28.9° (pre-brace) to 18.6° (immediate in-brace) while the mean Cobb's angle of group B decreased from 27.1° (pre-brace) to 22.5° (immediate in-brace). There was a significant difference (p < 0.05) in the correction of Cobb's angle between the two groups. The results showed that accurate pressure pad location does play an important role in the reduction of Cobb's angle and 3D CUS can be considered as a non-invasive and effective assessment tool to improve orthotic treatment of AIS.

An ICU clinical information system - clinicians' expectations and perceptions of its impact.
The Intensive Care Unit (ICU) is an information intense environment where Clinical Information Systems (CISs) can greatly impact patient care and the workload of clinicians. With the introduction of an ICU CIS imminent across New South Wales hospitals, we aimed to understand how ICU clinicians perceived a new system would impact on work practices in Australian ICUs, as much of the current evidence is generated from overseas. We conducted interviews with 66 doctors and nurses in 3 ICUs without a CIS. ⋯ This information provides valuable evidence in the Australian setting regarding clinicians' expectations of a new ICU CIS to assist with future implementations. It also provides baseline data as a foundation for future research once the CIS is implemented. It is clear that robust quantitative studies are required to gain a detailed understanding of how a new CIS will impact clinicians' work processes and that appropriate training is crucial for full benefits to be achieved.

Rate of surgery in a sample of patients fulfilling the SRS inclusion criteria treated with a Chêneau brace of actual standard.
Studies investigating the outcome of conservative scoliosis treatment differ widely with respect to the inclusion criteria used. Prospective cohort studies are available using the SRS inclusion criteria for studies on bracing. This seems to provide a great advantage to compare different strategies of bracing against each other. As we have gathered all data of the patients treated with a Chêneau light TM between June 2005 and November 2007 it was possible to identify the sample of patients fulfilling the SRS inclusion criteria from the whole sample. ⋯ Rate of surgery can be reduced with the help of Chêneau braces of the latest standard and satisfactory in-brace correction. Brace treatment with the Chêneau brace seems effective and therefore clearly is indicated. Clinical outcomes may be more important for the patient than radiologic outcomes.
