Text in English / The purpose of this research was to investigate occupational health and safety challenges and their impact on health care workers (HCWs) in selected public hospitals from the Gauteng Province, South Africa. Method: A quantitative descriptive cross-sectional survey was conducted among HCWs in the study sites. A two-staged sampling that include purposive sampling of study sites and census sampling of 2000 HCWs was used. Self-administered questionnaires were used to obtain data from HCWs. In addition, two different checklists were used to conduct retrospective records reviews to assess occupational health and safety (OHS) policy compliance and occupational injuries and diseases occurrence. The SAS Release 9.3 was used to analyse data. The Fischer Exact test and Chi-square were also used to determine the association of variables and P-value was set at <0.05 to indicate significant association. Results: A total of eight public hospitals and 926 (46.3%) HCWs who were all females nurses participated in this survey. Major occupational health hazards reported by the participants include: needle-stick injuries 275 (54.67%), slips trips and falls 67 (13.32%) and splashes 57 (11.33%). The analysis of open-ended responses indicated increased workloads, long hours of work and shift work as the most reported psychosocial hazards among HCWs. The reviewed records indicated that back injuries 22 (4.37%), tuberculosis (TB) 17 (3.38%) and asthmatic reactions 8 (1.59%) were the commonly reported occupational injuries and diseases among the HCWs. The records review also revealed a lack in the conducting of adequate medical surveillance among participants. The results showed poor compliance with the OHS policy and a negative impact of biological and psychosocial hazards on the HCWs. Conclusion: There was a high risk of exposures to biological hazards whilst providing care to patients, thus warranting the implementation of robust preventive measures. As a result, the guidelines were developed to promote the health and safety of HCWs with a view to promoting policy compliance and preventing the occurrence of occupational injuries and diseases as well as their impact among HCWs. / Health Studies / D.Litt et Phil.

The purpose of this study was to develop and test a measuring instrument based on the Gibb’s Defensive Communication Climate Paradigm (1961) to assess the communication climate focus of professional nurses in selected public hospitals in the Gauteng province. This focus involves the communication behaviour orientation of the professional nurses and their perceptions of the communication behaviour orientation of their operational managers. The Gibb’s model comprises six bipolar conceptual continuums, namely Evaluation-Description, Control-Problem orientation, Strategy-Spontaneity, Neutrality-Empathy, Superiority-Equality and Certainty-Provisionalism Continuums. The study consisted of a non-experimental design, including a developmental phase and a testing phase. During the developmental phase the researcher developed a measuring instrument (a Semantic Differential Scale questionnaire); used a simple, random sample method to pre-test the instrument; analysed the data by applying Cronbach’s Alpha reliability analysis and refined the instrument. Further refinement of this new instrument by future researchers is recommended. During the testing phase the researcher also used a simple, random sample, consisting of professional nurses (N = 270) from three selected public hospitals in Gauteng; tested the items against the biographical data and the three research questions and analysed the obtained data by utilising both descriptive and inferential statistics. A Delphi panel of experts were involved in both phases of the study. The results of the study indicated that although the respondents had a predominantly supportive communication behaviour orientation, they were more focused on the communication behaviour of their operational managers than on their own. Furthermore, the results indicated no significant differences in the influencing factors: age, tenure (periods in hospital), gender, language and institution (public hospital), in terms of the six conceptual continuums. Significant differences were found only in the factor: unit/ward, indicating that the supportiveness of the communication behaviour of professional nurses could be dependent on their specific work environment. Guidelines aimed at the development of a supportive climate were drawn up for the National Department of Health, Gauteng Department of Health, public hospitals, operational managers and professional nurses. It is recommended that implementation of the newly developed guidelines be pivotal for public hospitals, to refocus their communication climates towards supportive communication. / Health Studies / D.
