Effects of student-led drama on nursing students' attitudes to interprofessional working and nursing advocacy: A pre-test post-test educational intervention study

BACKGROUND

Nursing educators need to equip students to work in interprofessional teams and advocate for patients in increasingly integrated health and social care settings. Drama-based education has been used in nursing to help students understand complex concepts and practices, including communication, empathy, and patient safety. However, few studies have evaluated drama-based education to promote understanding of interprofessional care and advocacy, and none have involved student-led drama where students create dramatic performances to support learning.

OBJECTIVES

To examine the effects of student-led drama on student nurses' attitudes to interprofessional working and advocacy.

DESIGN

Pre-test post-test educational intervention study.

SETTINGS

Public university in Scotland.

PARTICIPANTS

400 undergraduate student nurses enrolled on a 15-week module focussed on health and social care integration and interprofessional working.

METHODS

Students completed paper questionnaires at the start (n = 274, response rate: 80.1 %) and end (n = 175, 63.9 %) of the module. Outcome measures were the validated Attitudes Towards Healthcare Teams Scale (ATHCTS) and Protective Nursing Advocacy Scale (PNAS). Change in mean ATHCTS and PNAS scores were assessed using paired samples t-tests, with Cohen's d to estimate effect size.

RESULTS

ATHCTS scores significantly increased from 3.87 to 4.19 (p < 0.001, d = 0.52). PNAS scores increased from 3.58 to 3.81 (p < 0.001, d = 0.79), with significant improvements in the 'acting as an advocate' (4.18 to 4.51, p < 0.001, d = 0.81) and 'environmental and educational influences' subscales (3.79 to 4.13, p < 0.001, d = 0.75). Statements focussed on promoting holistic, dignified care and enabling health professionals to be responsive to emotional and financial needs of patients, showed greatest change.

CONCLUSIONS

Education based on plays created and performed by student nurses led to significant improvements in student nurses' attitudes towards interprofessional working and nursing advocacy. Student-led drama should be embedded in nursing curricula to enable students to understand the realities and complexities of health and social care integration and interprofessional working.

Design, simulation and comparative analysis of CNT based cascode operational transconductance amplifiers

In this work, design and calibrated simulation of carbon nanotube field effect transistor (CNTFET)-based cascode operational transconductance amplifiers (COTA) have been performed. Three structures of CNTFET-based COTAs have been designed using HSPICE and have been compared with the conventional CMOS-based COTAs. The proposed COTAs include one using pure CNTFETs and two others that employ CNTFETs, as well as the conventional MOSFETs. The simulation study has revealed that the CNTFET-based COTAs have significantly outperformed the conventional MOSFET-based COTAs. A significant increase in dc gain, output resistance and slew rate of 81.4%, 25% and 13.2%, respectively, have been achieved in the proposed pure CNT-based COTA in comparison to the conventional CMOS-based COTA. The power consumption in the pure CNT-COTA is 324 times less in comparison to the conventional CMOS-COTA. Further, the phase margin (PM), gain margin (GM), common mode and power supply rejection ratios have been significantly increased in the proposed CNT-based COTAs in comparison to the conventional CMOS-based COTAs. Furthermore, to see the advantage of cascoding, the proposed CNT-based cascode OTAs have been compared with the CNT-based OTAs. It has been observed that by incorporating the concept of cascode in the CNTFET-based OTAs, significant increases in gain (12.5%) and output resistance (13.07%) have been achieved. The performance of the proposed COTAs has been further observed by changing the number of CNTs (N), CNT pitch (S) and CNT diameter (DCNT) in the CNTFETs used. It has been observed that the performance of the proposed COTAs can be significantly improved by using optimum values of N, S and DCNT.
