This study aimed at investigating nurse preceptors’ perceptions of use, intention to use and self-efficacy towards digital technology in preceptorship in the Cape Coast Metropolis of Ghana. Methods A concurrent type of mixed-methods design with a non-randomised interventional study using three-phase multi-methods technique was conducted among nurse preceptors in the Cape Coast Metropolis in the Central Region of Ghana. Forty-five nurse preceptors participated in a pre and post training intervention while seven were purposively selected for the qualitative interview. Complimentarity method of triangulation was used in the analysis. The quantitative data were analysed with STATA version 16 and presented using frequencies, percentages, means with standard deviations and McNemar's test while qualitative data were analysed using th...

Materials and Methods: The 1st phase of the study made use of 30 Sprague-Dawley rats aged 4 weeks. Two rats were culled each week for 15 weeks, the femoral bones of the rats were then harvested. Histological sections of the distal femora were prepared and studied. The 2nd phase involved 32 animals that were randomly assigned to four groups of 8 animals each. (Group A to D) Group A was given oral antimalarial drugs only, Group B was inoculated with Plasmodium berghei (NK65) only, Group C was inoculated with P. berghei (NK65) and treated with oral antimalarial drug, and Group D animals were neither inoculated nor given antimalarial drugs. At the end of the experiment histological sections of the femoral epiphysis of the rats were prepared and studied. Results: The microscopic architecture of the epiphyseal cartilage changed significantly as the animals aged. Significant differences were observed in mean bone thickness of the various experimental groups. There was however no significant difference in the mean cartilage thickness when comparison was made within the various groups. Conclusion: Although recurrent bouts of malaria infection appear not to alter the normal histological changes that occur in epiphyseal bone and cartilage layers, it most likely has an adverse effect on the rate of bone tissue deposition.

Such gaps contribute to errors, a significant cause of death in the United States. Method Framed by Ericsson's Expertise Theory, 20 teams of interprofessional health science students rotated through four scenarios with built-in medication errors after exposure to TeamSTEPPS® Essentials skills. Results Huddles improved in size and duration between rounds one and four. Huddle duration was inversely associated with care delays and patient harm. Attitudes toward teamwork improved significantly. Conclusions Multistation simulations facilitate deliberate practice of skills, enabling student improvement over time in critical competencies.

This study aimed to examine the diagnostic accuracy of KTS in predicting emergency department outcomes using timely injury estimation with Abbreviated Injury Scale (AIS) score and physician opinion to calculate KTS scores. This was a diagnostic accuracy study of KTS among injured patients presenting to Komfo Anokye Teaching Hospital A&E, Ghana. South African Triage Scale (SATS); KTS component variables, including AIS scores and physician opinion for serious injury quantification; and ED disposition were collected. Agreement between estimated AIS score and physician opinion were analyzed with normal, linear weighted, and maximum kappa. Receiver operating characteristic (ROC) analysis of KTS-AIS and KTS-physician opinion was performed to evaluate each measure's ability to predict A&E mortality and need for hospital admission to the ward or theatre. A total of 1053 patients were sampled. There was moderate agreement between AIS criteria and physician opinion by normal (κ=0.41), weighted (κlin=0.47), and maximum (κmax=0.53) kappa. A&E mortality ROC area for KTS-AIS was 0.93, KTS-physician opinion 0.89, and SATS 0.88 with overlapping 95% confidence intervals (95%CI). Hospital admission ROC area for KTS-AIS was 0.73, KTS-physician opinion 0.79, and SATS 0.71 with statistical similarity. When evaluating only patients with serious injuries, KTS-AIS (ROC 0.88) and KTS-physician opinion (ROC 0.88) performed similarly to SATS (ROC 0.78) in predicting A&E mortality. The ROC area for KTS-AIS (ROC 0.71; 95%CI 0.66-0.75) and KTS-physician opinion (ROC 0.74; 95%CI 0.69-0.79) was significantly greater than SATS (ROC 0.57; 0.53-0.60) with regard to need for admission. KTS predicted mortality and need for admission from the ED well when early estimation of the number of serious injuries was used, regardless of method (i.e. AIS criteria or physician opinion). This study provides evidence for KTS to be used as a practical and valid triage tool to predict patient prognosis, ED outcomes and inform referral decision-making from first- or second-level hospitals in LMICs.
