Dissertation presented to the Faculty of Health Sciences at the Durban University of Technology in partial compliance with the requirements for a Master’s Degree in Technology: Chiropractic, 2009 / Background: In order to develop a balanced healthcare system, healthcare integration and inter-professional communication is important and allows for optimum healthcare benefits for a patient and improves cost-effectiveness. The chiropractic profession has been trying to improve inter-professional communication with the medical profession. Kimberly Hospital Complex (KHC) is a tertiary provincial hospital situated in the Northern Cape and since 1998, a permanent chiropractic post exists at this hospital, making it the only state hospital in South Africa with a full-time chiropractic clinic and post. Purpose: To determine the knowledge and perceptions of the medical staff about chiropractic at KHC. Method: This study was achieved by means of a questionnaire, which was modified to suit a South African context by means of a focus group. The questionnaire was personally delivered to 975 medical staff members at KHC. A response rate of 30% (n = 292) was achieved and the data was analysed using SPSS version 15 (SPSS Inc., Chicago, III, USA). Results: The mean age of the respondents was 37.3 years and most were female (78.9%, n = 289). Doctors (62.5%, n = 54) and therapists (61.6%, n = 10) had a higher knowledge percentage score than nurses (48%, n = 213) or other healthcare professions (56.8%, n = 15). Doctors (77.8%, n = 42), therapists (100%, n = 10) and other healthcare professions (69.2%, n = 9) were more inclined to think that chiropractic is an alternative healthcare service, while nurses perceived chiropractic as a primary healthcare service (43.3%, n = 91). Many respondents were unaware of the fact that Diagnostics, Emergency Medical Care, Pharmacology and Radiology are included in the chiropractic curriculum and that chiropractic leads to a Master’s degree. Seventy five percent (n = 203) believed that chiropractors are competent in the general medical iv management of patients, but they would still rather refer patients to physiotherapists and orthopaedic surgeons. Despite the poor level of knowledge of chiropractic, 79.2% (n = 224) believed that it is sufficiently different from physiotherapy to warrant two separate professions and few (24%, n = 69) perceived it as unscientific. A large proportion of the respondents (80.3%, n = 228) believe that chiropractic is not well promoted in South Africa and only 20.8% (n = 59) felt that they know enough about the profession to advise a patient. The majority wanted to learn more about the chiropractic profession (95.8%, n = 277), especially pertaining to the scope and the treatment employed by chiropractors. Seventy-nine percent (n = 212) believed that patients benefit from chiropractic at KHC and 95.4% (n = 268) felt that South African hospitals would benefit from chiropractic care. Conclusion: Due to the poor level of knowledge at KHC, an educational drive should be employed to educate the medical staff in order to increase their understanding of chiropractic and to aid chiropractic integration into the state hospital system of South Africa.

Objectives: To identify the perceptions of community hospital physicians on computerized physician order entry. Design: Multi-method approach consisting of a mail survey of 659 community hospital physicians with active admitting privileges at three PeaceHealth, Inc., along with follow-up personal interviews with stratified random selection from completed survey. Measurements: Perceptions were assessed by means of a mail survey that asked physicians to rank themselves on a scale that represented the five adopter categories contained in the Diffusion of Innovation (DOI) change theory, along with several questions regarding computer use and attitudes toward potential effects of computers and CPOE on medicine and healthcare. Physicians representing four of the five adopter categories were interviewed to assess general perceptions and perceived attributes of innovations, an another construct within the DOI theory. Results: The response rate was 41%. Medical specialty, years in practice, and gender were found not to influence attitudes toward use of computers or, more specifically CPOE in medicine and healthcare. However, more medical specialists favor CPOE implementation at PeaceHealth than expected. Self-ranking on the DOI five adopter categories appears to influence attitudes toward use of computers in medicine and healthcare with positive trends in improving quality, rapport, and patient satisfaction mainly in the Innovator, Early Adopter, and Early Majority categories. A positive trend was seen in the relationship between CPOE's potential effects on improving patient care, not interfering with communication, and improving patient satisfaction with negative relationships with impact on physician workflow and enjoyment of medical practice. A relationship is seen between the five adopter categories and favoring CPOE implementation at PeaceHealth. The perceived attributes of innovations of Ease of Use, Result Demonstrability, and Visibility were supported by interview responses. Relative Advantage seemed to be supported by other questions. The concept of Compatibility was also supported. No steps of the processes of change construct within the Transtheoretical Model were identified during the interviews. Conclusions: This study appears to refute the suggestion that there might be a difference between medical specialists and surgical specialists, age, or gender in their support of computers and specifically CPOE. These data appear to support the Diffusion of Innovation theory is appropriate to consider in investigating CPOE and its diffusion among community hospital physicians. Implementing CPOE according to adopter categories would provide the option for interested physicians to use CPOE, to use CPOE on certain hospital units or patients, and to expand its use before making mandatory. Communication should be targeted toward the adopter categories rather than mass media and emphasize the perceived attributes of innovation. / Graduation date: 2004

In this thesis the applicability of a hospital patient flow model is used in addressing hospital resource allocation problems. Three separate but interrelated models are presented. First, the hospital patient flow model is discussed. The main feature of the hospital patient flow model is the matrix of technical coefficients, which gives the probability of patient transfers throughout the hospital. Given the hospital system's daily patient input, the model provides the patient demands upon the different hospital services. Results from the patient flow model are used in the development of a staff allocation model. The staffing model involves the minimization of a weighted quadratic penalty function. The weighting factors are based on the proportion of patients in each of three carelevels in the wards. The weights are also dependent upon whether overstaffing or understaffing is the situation. Constraints to the model include a desirable mix and number of the available nursing staff. Solution of the allocation model is obtained by using SUMT with a pattern search. A third model concerned with predicting hospital revenues is presented. Again, results from the hospital patient flow model are used to present estimates of the expected values and variance of a hospital's revenue. To illustrate the use of the models, results from a two-week study period of the Montgomery County Hospital are presented and discussed. / Master of Science

Submitted in fulfillment of the requirements for the degree of Master’s of Technology: Radiography, Durban University of Technology, Durban, South Africa, 2015. / Introduction Tuberculosis remains a leading cause of death, second to the Human Immunodeficiency Virus. The risk of latent tuberculosis infection and active tuberculosis disease is a known occupational hazard. In South Africa, a high tuberculosis burden country, the potential of Mycobacterium tuberculosis transmission to health care workers is high. This includes diagnostic radiographers and other radiology staff working in radiology departments. Purpose of the Study This study aimed to investigate the association of demographic and occupational factors with latent tuberculosis infection in radiology staff in public sector hospitals of the eThekwini Health District. Methodology This cross-sectional study was conducted from 26 February 2013 to 07 June 2013. Quantitative methods were used to test for associations of demographic and occupational factors with latent tuberculosis infection in participants. A sample size of 181 participants for an estimated population of 340 radiology staff was recommended at the proposal stage. The study consisted of two phases; the questionnaire survey (phase one) and the administration of a two-step tuberculin skin test (phase two). Data was obtained with regard to demographics, occupational history, social behaviours, medical history; and family and home histories. Demographic and occupational associations with latent tuberculosis infection were made in relation to the size of the first tuberculin skin test induration. Frequency distributions were developed to describe data categories. Pearson’s and Spearman rho’ correlation coefficients were used to test for correlations between the independent variables. The chi-square test was used to determine associations between the categorical independent variables and the dependent variable. Bivariate analyses were performed using these tests. The multivariate analysis was performed using logistic and linear regression on the dependent variable. Results A total of 182 questionnaires were returned from approximately 280 radiology staff. At the outset, all doctors working in the radiology department had to be excluded due to numerous failed attempts to enlist their participation. Fifty-three (29.12 percent) participants were excluded from phase one of the study and a further thirteen participants were excluded from phase two. The total sample was 116 participants. Of the 116 participants, 86.2 percent tested positive for latent tuberculosis infection at the first step of the two-step testing method used. One (0.86 percent) participant went on to convert at the second step, testing positive at this level. Demographic associations with latent tuberculosis infection included age (older) as an associated factor. A significant demographic association with latent tuberculosis infection was the use of alcohol (p-value 0.033 on the multivariate analysis). Occupational associations with latent tuberculosis infection included longer durations of employment. The annual income (higher income earners) displayed significant associations with latent tuberculosis infection (p-value 0.048 on the multivariate analysis). It is necessary in this study to note that participants include support personnel (lower income earners) making up 37.8 percent of the study, diagnostic radiographers making up 48.3 percent; and radiography managers/assistant managers (highest income earners) making up 13.8 percent of the study. Conclusion and recommendations The risk of transmission of Mycobacterium Tuberculosis to health care workers is a known occupational hazard. This study has described the prevalence of latent tuberculosis infection in radiology staff, at district and regional hospitals within the eThekwini Health District. With 23.62 percent of all participants already having active TB disease and 86.2 percent of the tested group displaying positive results for latent tuberculosis infection, using the tuberculin skin tests, the need for tuberculosis screening is essential. The findings of this study will be used as a health improvement mechanism for stakeholders, having identified potential gaps in medical screening in healthcare in Kwa-Zulu Natal. This study makes recommendations for the early detection of active tuberculosis infection and the monitoring of health care workers that are latently infected, thus assisting in reducing the rate of conversion of latent tuberculosis infection to active tuberculosis disease in radiology staff. This reduces long-term exorbitant costs related to health care associated infections, such as tuberculosis. It also reduces rates of transmission and cross infection to both co-workers and already immunocompromised patients, helping to curb the overall epidemic in South Africa.
