Item Private doctors' responses on the implementation of a National Health Insurance Scheme (NHIS)(2018) Botha, Cecilia LizaThere are numerous challenges and concerns, about a future mandatory National Health Insurance Scheme. The proposed South African NHI scheme, is that of capitation and a single-payer model in order to achieve Universal Heath Coverage. The objectives of this study, focused on exploring opinions and responses of medical doctors working in two private health care institutions. [Abbreviated Abstract.

They were interviewed to determine demographic characteristics and attitude towards sleep and sleep problems. Subjects living in the frail care facility were compared to those living independently. In addition, the chronic use of benzodiazepines, and the perceptions of both the subjects, and the medical and nursing personnel caring for them, was studied. The physical and mental status of subjects currently taking benzodiazepines was compared with those who were not. No significant differences in demographic features, was found between the frail and the non-frail subjects. However, when subjects taking benzodiazepines were compared with those who were not, several interesting differences were determined. Frail subjects were more likely to be taking benzodiazepines. Sleep difficulties, and perception of poor sleep quality was more likely in the benzodiazepine group. Subjects taking benzodiazepines were more likely to be anxious, and to have suffered falls and resulting injuries. The daily functioning of subjects was rated using three well-validated scales: Instrumental Activities of Daily Living, Mini Mental State Examination, and the Geriatric Depression scale. Those subjects taking benzodiazepines scored significantly worse on all of these scales, independent of frail status (i.e. within both frail and nonfrail groups, subjects taking benzodiazepines scored significantly worse). In spite of the above findings, subjects’ perception of benzodiazepines was positive, and they believed them to be helpful. Nursing staff also perceived benzodiazepines to be beneficial medications. Most of the general practitioners questioned had doubts as to the safety of benzodiazepine use in elderly patients, however they were also generally happy to continue to prescribe them.Item Factors supporting the intention to use e-prescribing systems: health professionals' use of technology in a voluntary setting(2013-07-16) Jones, Michael EdwardIllegible written prescriptions and “Doctor’s handwriting” may have been synonymous, but this stereotype has begun to change with the gradual uptake of e-prescriptions. These eprescriptions are electronically captured and delivered prescriptions, and are touted as the solution to the many medical risks caused by written prescriptions. Whilst there is published support for the benefits of e-prescriptions, the uptake of e-prescribing has been too gradual for all patients to enjoy these benefits. The inadequate research into physicians’ adoption of e-prescribing systems presents a need for further study in this area, in an effort to improve the general use of these systems. Based on a review of literature, this study proposes six factors which may explain physicians’ intentions to use e-prescribing systems. These factors are based upon the Unified Theory of Acceptance and Use of Technology (UTAUT). This model is extended in this study by Social Dominance Theory, Commitment-Trust Theory and the Product Evaluation Model. Quantitative data was collected to test the proposed hypotheses. This data was gathered from physicians who have had some exposure to an e-prescription system. 72 usable responses were obtained for this study. The results of the study suggest that Performance Expectancy and Price Value have the highest influence on Behavioural Intention. Effort Expectancy and Social Influence had no direct influence on Behavioural Intention when in the presence of other variables, but they, along with Trust, had an indirect effect on Behavioural Intention through Performance Expectancy. Surprisingly, Social Dominance Orientation was not found to have an influence on Behavioural Intention. Implications, contributions and further research are discussed.
