Service evaluation of radiographer-led vetting and protocoling of Computed Tomography (CT) scan requests in a Singapore public healthcare institution.

INTRODUCTION: A service improvement project involving the vetting and protocoling of Computed Tomography (CT) scan requests by qualified CT radiographers was initiated in 2018. AIM: This study provides a comprehensive evaluation of how a radiographer-led initiative aims to ensure that the CT scan requests received by the Radiology department are clinically appropriate, which in turn will reduce interruptions to the interpretation and reporting of imaging examinations by radiologists, who might otherwise be required to attend to clinically inappropriate and wrongly protocolled CT scan requests. METHOD: Outpatient CT scan requests received from July to October 2021 were vetted and protocolled by a qualified CT-trained radiographer for parameters which included the appropriateness of the clinical indication, adequacy of patient preparation for the scan, as well as the suitability of the requested examination protocol pertaining to the need for contrast media, multiple contrast-enhanced imaging phases, and the appropriateness of the scan range. RESULTS: Poor patient preparation and insufficient or inaccurate clinical indications were the most common findings during the vetting process (71%). Out of the 64 CT scan requests with protocol errors, 77% were attributed to contrast media type errors. The odds of incorrect CT scan requests increased with the requesting clinician's rank, while there was no such significant correlation with the clinical specialty of the requesting clinician or the CT scan type. CONCLUSION: The meticulous vetting of imaging requests helps to ensure that limited imaging hardware resources are allocated to more clinically appropriate cases, correct protocols are applied to requested imaging scans, and that patients undergoing imaging are adequately prepared, thereby enhancing overall patient care. IMPLICATIONS FOR PRACTICE: Vetting of imaging requests by radiographers, who are capable to make appropriate clinical decisions related to their enhanced level of practice ensures patient safety and optimisation of Radiology resources.

Tai Chi with music improves quality of life among community-dwelling older persons with mild to moderate depressive symptoms: A cluster randomized controlled trial.

Depression leads to a poorer quality of life (QOL) which is a determinant of healthy ageing. Cost-effective solutions for enhancing QOL in the older population are much needed in China, with its rapidly ageing population. We conducted a randomized controlled trial involving 112 community-dwelling older participants with mild to moderate depression, to evaluate the effect of Tai Chi with music on QOL (57 in intervention group, 55 in control group). WHO Quality of Life-BREF was used to measure QOL at baseline and at every month for three months. Following the adjustments for sociodemographic data, the effect of intervention on QOL was assured (F = 25.145, P < 0.001, ηp2= 0.435, F = 18.696, P < 0.001, ηp2= 0.364, F = 17.473, P< 0.001, ηp2= 0.348, and F = 29.576, P < 0.001, ηp2= 0.475 for physical, psychological, social, and environment domains respectively). This intervention represents an economically viable solution to better QOL and healthy ageing in a highly populous developing nation.

Factors associated with nurses' perceptions about quality of end-of-life care.

AIM: To examine the factors associated with nurses' perceptions of the quality of end-of-life care. BACKGROUND: With increasing demand for hospitals to provide end-of-life care, the low quality of palliative care provided in hospital settings is an issue of growing concern in developing countries. Most dying patients receive their care from general nurses, irrespective of the nurses' specialty or level of training. METHOD: A structured cross-sectional questionnaire survey was conducted of 553 nurses working at a teaching hospital in Malaysia. RESULTS: The mean scores for nurses' knowledge about end-of-life care, their attitudes towards end-of-life care and the perceived quality of end-of-life care were low. The factors identified as significantly associated with the quality of end-of-life care were nurses' levels of knowledge and their attitudes towards end-of-life care. DISCUSSION: Factors that contributed to the low quality of end-of-life care were inadequate knowledge and negative attitudes. These findings may reflect that end-of-life care education is not well integrated into nursing education. CONCLUSION: The findings of this study suggest that there is a need to increase the nurses' level of knowledge and improve their attitude towards end-of-life care in order to enhance the quality of care provided to dying patients. IMPLICATIONS FOR NURSING AND HEALTH POLICY: Nurse managers and hospital policymakers should develop strategies to enhance nurses' level of knowledge, as well as providing adequate emotional support for nurses who care for dying patients and their families. Nurses should be proactive in increasing their knowledge and adopting more positive attitudes towards end-of-life care.

The Impact of Combined Music and Tai Chi on Depressive Symptoms Among Community-Dwelling Older Persons: A Cluster Randomized Controlled Trial.

BACKGROUND: The effectiveness of pharmacological treatment may be limited in older persons. Several studies using Tai Chi or music therapy separately confirmed positive effects in the reduction of depressive symptoms. We conducted a cluster randomized controlled trial to evaluate the possible synergistic effect of combined music and Tai Chi on depressive symptoms. METHODS: One hundred and seven older adults with mild to moderate depressive symptoms were recruited from Ya'an city. Fifty-five participants were cluster randomized to combined music and Tai Chi group for three months, while the other fifty-two individuals were randomized to the control group that entailed routine health education delivered monthly by community nurses. The primary outcome of depressive symptoms was measured with the Geriatric Depression Scale (GDS) at baseline and monthly for three months. RESULTS: At three-month follow-up, a statistically significant improvement in depressive symptoms was found in the intervention group compared with control group (F(3,315) = 69.661, P < 0.001). Following adjustments for socio-demographic data, the true effect of intervention on depressive symptoms was significant (F = 41.725, P < 0.01, ηp2 = 0.574). CONCLUSIONS: Combined music and Tai Chi reduced depressive symptoms among community-dwelling older persons. This represents an economically viable solution to the management of depression in highly populous developing nations.

Redefining conversion in laparoscopic colectomy and its influence on outcomes: analysis of 418 cases from a single institution.

BACKGROUND: The reported rates of conversion in laparoscopic colectomy are varied. The incidence of conversion is not, however, well defined. The aim of the present study is to redefine conversion and to analyze differences in outcome. METHODS: Treatment parameters of a total of 418 consecutive patients who underwent laparoscopic colonic resection from 2005 to 2007 were analyzed. Treatment was classified as laparoscopic colonic resection, laparoscopy-assisted colonic resection (lap-assisted), and laparoscopic conversion. RESULTS: There were significant differences in median operating time between laparoscopic colonic resection, lap-assisted, and laparoscopic conversion (125 min, 160 min, and 140 min; p = 0.0001); median hospital length of stay was significantly different (laparoscopic, 5.0 days, versus lap-assisted, 6.0 days, versus laparoscopic conversion, 6.5 days; p = 0.0001); and median incision length was also noted to vary significantly (laparoscopic, 5.0 cm, lap-assisted, 8.0 cm, and conversion, 12.0 cm; p = 0.00001). Multivariate analysis reveals that older age (Odds Ratio [OR] = 1.07, 95% Confidence Interval [CI] = 1.02-1.12), higher Body Mass Index ([BMI], OR = 1.15, 95% CI = 1.03-1.29), and pT stage were significant factors affecting conversion. Disease-free survival for cancers was not influenced by conversion (p = 0.653). The overall complication rate was 16.7% and was significantly increased in lap-assisted cases and in conversion cases (26% versus 13%; p = 0.003). CONCLUSIONS: A consistent definition for conversion in laparoscopic colonic resection is required. Our proposed definitions may provide a solution. The definition of lap-assisted as a separate entity serves as a bridge between laparoscopy and full conversion. Risk factors of age, BMI, and advanced tumor stage are conversion predictors and are associated with increased hospital stay and postoperative morbidity.

Altered cellular but not humoral reactions in children with complicated enterovirus 71 infections in Taiwan.

Enterovirus 71 (EV 71) infections have high neurovirulence and fatality. Immune responses were assessed in 78 patients with EV 71 infection. EV 71 meningoencephalitis occurred more frequently in younger children and in boys. C-reactive protein levels were not elevated, although total leukocyte counts were increased in these patients. The CD40-ligand expression on T cells significantly decreased in children with meningoencephalitis (P=.041). Polymorphism of the cytotoxic T lymphocyte antigen-4 (CTLA-4) at position 49 of exon 1 showed a higher frequency of G/G genotype in patients with EV 71 meningoencephalitis than in those without meningoencephalitis (18/31 vs. 14/47; P=.045) and in control subjects (18/31 vs. 25/93l; P=.007). Specific EV 71 neutralizing antibody titers were detectable but did not differ in children with and without meningoencephalitis in the acute and convalescent stages. Results from this study suggest that younger children with a certain CTLA-4 polymorphism and altered cellular but not humoral response may be linked to EV 71 meningoencephalitis.
