Item Biokineticist and physiotherapist attitudes in Gauteng towards overweight and obese individuals(2017) Jordaan, Darrin ChristopherIntroduction. Obesity levels have doubled since the 1980s and health professionals have been documented to show weight bias and stigma towards these overweight individuals. Research in South Africa on weight bias has not as yet been conducted. This study aimed to examine bias and prejudice toward overweight and obese individuals in Biokineticists and Physiotherapists Methods. The Fat Phobia Scale (FPS) and The Attitudes Towards Obese Persons (ATOP) questionnaire were used to access bias and prejudice attitudes in the sample of Biokineticists and Physiotherapists. The FPS is a 14-item scale consisting of a five-point semantic differential scale. The ATOP is a 20 point questionnaire that requires a rating of a statement from -3 to +3. Results. A total of 223 Biokineticists and Physiotherapists in the study. Biokineticists were significantly more bias towards overweight and obese patients on both the FPS (p=0.04) and ATOP (p<0.01). Females were also shown to be more prejudice than men (p=0.01), and there was an inverse relationship between the BMI of the healthcare worker, and the fat phobia scale (p=0.02). Lastly, the amount of overweight/obese patients (p=0.56), the age of the healthcare professional (p=0.74) and years of practice did not appear to affect bias and prejudice in this study (p=0.13). Conclusion. These results provide a platform for future research into bias and prejudice for South African health professionals. Future research should include implicit bias and prejudice measures as this study only looked at explicit bias and prejudice.Item The scope of practice of physiotherapists who work in intensive care in South Africa: a questionnaire-based survey(2015-09-17) Lottering, Michele AndersonPatients admitted to the intensive care unit (ICU) require continuous monitoring and care from all staff working in ICU; this includes doctors, nursing staff, physiotherapists, dieticians and various other medical staff. Conventionally ICU was predominantly staffed by physicians and nursing personnel, with other members of health care having a minor part to play in the patient’s care whilst in ICU. Depending on the country, type of unit, amount of staff and level of training, the physiotherapist may screen the patients to assess if they require physiotherapy and if so, what intervention will be required; on the other hand, in some units the physiotherapist may rely on referral from the doctors and administer the treatment requested by the doctor for the particular patient. In 2000, Norrenberg and Vincent conducted a study to establish the profile of physiotherapists working in ICU in Europe. Van Aswegen and Potterton (2005) adjusted the questionnaire compiled by Norrenberg and Vincent (2000) to be more suitable for the South African setting. A pilot study using this questionnaire was done to determine the scope of practice of physiotherapists in ICU in South Africa. The content of the modified questionnaire used by Van Aswegen and Potterton (2005) was not validated prior to its implementation and a sample of convenience was used. Results reported from that survey were therefore only preliminary and no additional surveys had been performed to date. Objectives: The aim of this study was to establish the current scope of practice of physiotherapists in ICU in South Africa. To determine if physiotherapists’ scope of practice in ICU in South Africa has changed since the report published by Van Aswegen and Potterton (2005). To compare South African physiotherapists’ scope of practice in ICU with that reported on an international level. Methodology: A pre-existing questionnaire used by Van Aswegen and Potterton (2005) was content validated for this study. After consensus was reached on the final version of this questionnaire, it was uploaded onto SurveyMonkey. Physiotherapists that worked in ICU in the government sector, hospitals belonging to the Life, MediClinic and NetCare groups or that were members of the Cardiopulmonary Physiotherapy Rehabilitation Group of the South African Society of Physiotherapy were invited to participate in this study. Results: A total of 319 questionnaires were sent out and 108 responses were received. The combined response rate for this survey was 33.9%. An assessment technique that was performed ‘very often’ by respondents was an ICU chart assessment (n=90, 83.3%), auscultation (n=94, 81, 8%) and strength of cough effort (n=81, 75%). Assessment techniques that were ‘almost never’ or ‘never’ used included assessment of lung compliance (n=75; 69.4%), calculation for the presence of hypoxemia (n=74; 68.5%) and patient readiness for weaning (n=63; 58.3%). Treatment techniques performed by respondents ‘very often’ included manual chest clearance techniques (n=101, 93.5%), mobilising a patient in bed (n=91, 84.3%), positioning a patient in bed (n=91, 84.3%), airway suctioning (n=89, 82.4%), mobilising a patient out of bed (n=84, 77.8%), deep breathing exercises (n=83, 76.9%) and peripheral muscle strengthening exercises (n=79, 73.1%). Treatment techniques that were ‘never’ or ‘almost never’ used included the flutter device (n=77, 71.3%), implementation and supervision of non-invasive ventilatory support (n=77, 71.3%) and adjustment of mechanical ventilation settings for respiratory muscle training (n=76, 70.4%). Physiotherapists working in the private sector made up 60.2% (n=65) of the respondents. An afterhours physiotherapy service was provided to ICU patients by 78 (72.2%) of the respondents during the week. One hundred and five (97.2%) of the respondents provided a physiotherapy service for ICU patients over the weekend. When comparing the results of the current study to the studies by Norrenberg and Vincent (2000) and Van Aswegen and Potterton (2005), there was a significant difference (p < 0.05) in the usage of IPPB/NIPPV, weaning patients from MV, adjustment of MV settings and IS between the studies. Results from the current study showed a significant difference (p < 0.05) in the involvement of respondents in suctioning, extubation and adjustment of MV settings compared to that reported by Norrenberg and Vincent (2000). Conclusion: Physiotherapists in this study performed a multisystem assessment of their patient’s which is important since physiotherapists are first line practitioners in South Africa. Physiotherapists play an important role in treating and preventing respiratory and musculoskeletal complications that occur in ICU. The results from this study showed that physiotherapists in South Africa are treating their patient’s according to evidenced based practice but due to the high nonresponse bias these results should be interpreted with caution. The results from this study can be used to develop preliminary clinical practice guidelines for physiotherapists working in ICU in South Africa.
