The development of a clinical management algorithm for early physical activity and mobilization of critically ill patients : synthesis of evidence and expert opinion and its translation into practice
(Sage publishers, 2011-04) Hanekom, Susan; Gosselink, Rik; Dean, Elizabeth; Van Aswegen, Helena; Roos, Ronel; Ambrosino, Nicolino; Louw, Quinette
Objective: To facilitate knowledge synthesis and implementation of evidence supporting early physical activity and mobilization of adult patients in the intensive care unit and its translation into practice, we developed an evidence-based clinical management algorithm. Methods: Twenty-eight draft algorithm statements extracted from the extant literature by the primary research team were verified and rated by scientist clinicians (n¼7) in an electronic three round Delphi process. Algorithm statements which reached a priori defined consensus – semi-interquartile range <0.5 – were collated into the algorithm. Results: The draft algorithm statements were edited and six additional statements were formulated. The 34 statements related to assessment and treatment were grouped into three categories. Category A included statements for unconscious critically ill patients; Category B included statements for stable and cooperative critically ill patients, and Category C included statements related to stable patients with prolonged critical illness. While panellists reached consensus on the ratings of 94% (32/34) of the algorithm statements, only 50% (17/34) of the statements were rated essential.
The implementation and evaluation of a best practice physiotherapy protocol in a surgical ICU
(Stellenbosch : University of Stellenbosch, 2010) Hanekom, Susan; Louw, Q. A.; Coetzee, Andre; University of Stellenbosch. Faculty of Health Sciences. Dept. of Interdisciplinary Sciences
ENGLISH ABSTRACT: Introduction: It is increasingly being recognized that how intensive care services are delivered may have a greater impact on patient outcome than the individual therapies. Uncertainty regarding the optimal physiotherapy service provision model in a surgical intensive care unit (ICU) exists. Methodology: The aims of this study were to 1) develop an evidence-based physiotherapy protocol; 2) validate the content of the protocol; and 3) conduct an explorative intervention trial to compare usual care to the estimated effects of providing a physiotherapy service guided by an evidence-based physiotherapy protocol by a dedicated physiotherapist. A systematic review process was used to synthesize the evidence in eight subject areas. The GRADE system was used to formulate best practice recommendations and algorithm statements. Forty-two experts from a variety of disciplines were invited to participate in a Delphi process. Finally, the evidence-based physiotherapy protocol was implemented in a surgical ICU over four three-week intervention periods by a group of research therapists. The outcomes measured included ventilator time, ventilation proportions, failed extubation proportions, length of ICU and hospital stay, mortality, functional capacity, functional ability and cost (using nursing workload as proxy). Results: Fifty-three research reports in eight subject areas were identified, 23 draft best-practice recommendations and 198 algorithm statements were formulated. The draft protocol consisted of five clinical management algorithms. Fifteen international research experts and twelve national academics in the field of critical care agreed to participate in the Delphi process. Consensus was reached on the formulation of 87% (20/23) recommendations and the rating of 66% (130/198) statements. The risk of an adverse event during the protocol care intervention period was 6:1000 treatment sessions (p=0.34). Patients admitted to the unit during the protocol care intervention period were less likely to be intubated (RR 0.16 95%CI 0.07 – 0.71; RRR 0.84 NNT 5.02; p=0.005) or fail extubation (RR 0.23 95%CI 0.05 – 0.98; RRR =0.77 NNT 6.95; p=0.04). The mean difference in the daily unit TISS-28 score between the two condition periods was 1.99 95%CI 0.65 – 3.35 (p=0.04). Patients managed by the protocol tended to remain in the hospital for a shorter time after unit discharge (p=0.05). There was no difference in the time spent on the ventilator (p=0.50), mortality (p=0.52) or in the six minute walk distance (p=0.65). In addition there was no difference in the proportion of patients who reached independence in any of the Barthel Index activities measured within 48 hours of discharge from the unit. Conclusions: The use of an evidence-based physiotherapy protocol for the comprehensive physiotherapeutic management of patients in a surgical ICU was feasible and safe. The preliminary results of this study suggest that a physiotherapy service, which is guided by an evidence-based protocol and offered by a dedicated unit therapist, has the potential to lower the cost of ICU care and facilitate the functional recovery of patients after unit discharge. This information can now be considered by administrators to optimize the physiotherapy service provided in ICU.
Mapping of a curriculum renewal journey : lessons learned
(Health & Medical Publication Group, 2014-10) Hanekom, Susan
A curriculum is described as an expression of educational ideas in practice.[1] It is a living document which should be adaptable to a changing environment. When faced with specific contextual challenges that required curriculum renewal, we took a phronetic approach. The process was predominantly based on craft knowledge and relied in most part on the insightfulness of staff. The curriculum renewal provided a unique opportunity to evaluate both the content and the mode of delivery. In this edition of AJHPE we share the valuable lessons learned along the journey of curriculum renewal. We started with the end in mind by defining the profile of the Stellenbosch University physiotherapy graduate (Table 1).
Patient-reported outcome measures in key African languages to promote diversity in research and clinical practice (PROUD)—protocol for a systematic review of measurement properties
(BMC (part of Springer Nature), 2021-06-05) Heine, Martin; Mokkink, Lidwine B.; Van Zyl, Chanel; Derman, Wayne; Hanekom, Susan
Introduction: Sub-Saharan Africa is a subcontinent with a proud cultural richness and diversity, yet inexplicably also a region with severe health care challenges and inequity. To challenge this health equity gap and reduce the burden of disease, the patient’s voice in monitoring and evaluation of health and health care interventions is paramount. The aim of this two-phased review is to map the availability of patient-reported outcome measures (PROMs) in a selection of non-English, African Languages, and systematically evaluate the measurement properties of the PROMs that were identified. Methods: This systematic review will be conducted in two phases. In phase 1, we will scope the literature for patientreported outcome measures (PROMs), either developed from scratch or through translation and validation in a sub-Saharan African country and a selection of non-English, African languages (n = 31; spoken in > 10 million people and/or a national language). The availability of PROMs will be mapped against the previously reported burden of disease in the respective countries included. Subsequently, in phase 2, we systematically evaluate the measurement properties of these PROMs using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) methodology for systematic reviews on PROMs. To ensure rigour, secondary searches will be developed to specifically locate articles that report on the measurement properties of the PROMs identified during phase 1. The evidence will be graded using the modified GRADE approach. Discussion: This review will provide a comprehensive overview and quality appraisal of PROMs developed in non-English, African languages. Consequently, this review when concluded may be an important first step in promoting access to these PROMs for use in clinical practice and research, as well as facilitate identification and prioritization of key knowledge gaps.
Physiotherapy in the intensive care unit
(Health & Medical Publishing Group, 2016) Hanekom, Susan
ENGLISH SUMMARY : While physiotherapy has been recommended by scientific societies as integral to the management of critically ill patients, great variation has been reported in the role of the physiotherapist in the intensive care unit (ICU), the service provided and the techniques used.[1] Clearly, this may impact on patient outcome. In a bid to address these variations, ICU physiotherapists have taken the initiative to drive a research agenda and to standardise clinical pathways to facilitate optimal patient outcome.
Post-tuberculosis health-related quality of life, lung function and exercise capacity in a cured pulmonary tuberculosis population in the Breede Valley District, South Africa
(AOSIS, 2019) Daniels, Kurt J.; Irusen, Elvis; Pharaoh, Hamilton; Hanekom, Susan
Background: Pulmonary tuberculosis (PTB) remains a major concern worldwide. Albeit curable, PTB continues to negatively affect patients’ health-related quality of life (HRQoL) and functioning even after cure. Objectives: To describe the demographics, respiratory symptoms, pulmonary airflow patterns, HRQoL and exercise capacity of cured PTB patients, in the Breede Valley district of South Africa. Methods: A cross-sectional study conducted at five primary health care facilities included adult patients diagnosed with PTB, who had completed anti-tuberculosis treatment. Post-treatment bronchodilator lung function, HRQoL and 6-min walk distance (6MWD) were measured. Results: Three hundred and twenty-four patients were screened. Specific challenges resulted in 45 patients being included (male n = 25 [56%]; mean population age 39.9 [± 10.2]). HRQoL was assessed using the short-form 12v2, part of the burden of lung disease core questionnaire. In general, self-reported physical scores (physical health component summary score = 45) were higher than mental scores (mental health component summary score = 39). The mean 6MWD was 294.5 m (± 122.7) m (range 110 m – 600 m), which is well below normal reference values. Forty-eight percent (48%) of the sample presented with abnormal lung function, including obstructive (n = 9; 21%), restrictive (n = 11; 25%) and mixed (n = 1; 2%). Conclusions: This pilot study suggests that most cured PTB patients have decreased HRQoL, exercise capacity and abnormal lung function. This study is the first to describe the combination of these three outcomes in a South African population.
The profile of a surgical ICU in a public sector tertiary hospital in South Africa
(Stellenbosch : University of Stellenbosch, 2004-12) Hanekom, Susan; Faure, M.; Coetzee, Andre; University of Stellenbosch. Faculty of Health Sciences. Dept. of Interdisciplinary Health Sciences. Physiotherapy.
ENGLISH ABSTRACT: Objective: To describe the baseline data of a surgical ICU in South Africa before the implementation of an evidence-based physiotherapy practice protocol. Design: Prospective cohort observational study Setting: Ten-bed closed surgical unit in a university affiliated tertiary hospital. Patients: All adult ICU admissions from 16 June - 30 September 2003. Measurements: The patient’s clinical data including demographic information, admission diagnosis, surgery classification and co-morbidities were recorded on admission to the unit. APACHE II score was calculated. The physiotherapy techniques, positions and functional activities used, the frequency and duration of physiotherapy treatment sessions, the provision of after-hours service and the diagnosis of pulmonary complications were also recorded daily. The time of mechanical ventilation was calculated and the number of re-intubations documented. The ICU length of stay or mortality was recorded. Results: 160 patients were admitted. Patients were 49 +/- 19.95 years of age. The mean APACHE II score was 12.3 +/ 7.19 and a 12.3% mortality was observed. Thirty seven percent of patients were admitted to the unit following elective surgery. Patients stayed in the unit for 5.94 +/- 6.55 days. Hypertension was the most frequent co-morbidity found in this cohort (42%), and 21% of patients tested, tested positive for HIV. Co-morbidities had no significant association with ICU LOS or mortality. Nine hundred and twenty seven physiotherapy records were obtained. Students were responsible for 39% (n=366) of treatment sessions, the unit therapist for 34% (n=311) and the on-call therapists for 27% (n=250). Despite routine daily physiotherapy for all patients in the unit, 39% (n=62) developed excessive secretions, 30% (n=48) of patients developed pneumonia and 27% (n=43) of patients were diagnosed with basal atelectasis. Nineteen patients (12%) died in the ICU. Patients spent a mean of 5.94 (SD 6.55) days in the unit. One hundred patients (63%) were ventilated. Almost a third of ventilated patients (31%) were intubated more than once. The patients spent a mean time of 3.8 days (SD 6.30) on the ventilator every time they were re-intubated. The development of pulmonary complications significantly increased the time on the ventilator and the LOS. Conclusions: This baseline study of a surgical ICU presents a picture of a unit providing care comparable to first world environments. The picture of the physiotherapy service provided in this unit is of a “traditional” service based neither on the available evidence regarding the prevention or management of pulmonary complications, nor on the incorporation of early rehabilitation into the management of mechanically ventilated adult patients in ICU.
Reliability of ultrasonic diaphragm thickness measurement in mechanically ventilated infants and children : a pilot study
(Health & Medical Publishing Group, 2018) Terhart, M. N.; Hanekom, Susan; Lupton-Smith, A.; Morrow, B.
Background: Diaphragmatic atrophy in mechanically ventilated infants and children may be due to ventilator-induced diaphragmatic dysfunction, which could lead to extubation failure. Ultrasound may be used as a means by which diaphragmatic atrophy can be reliably identified. There are currently no data reporting on the use of ultrasound to monitor diaphragm atrophy in the paediatric population. Objectives: To assess the inter- and intra-rater reliability of using ultrasound to measure diaphragm thickness in mechanically ventilated infants and children. Method: Diaphragm thickness measurements were compared between two individual researchers for inter-rater reliability and between multiple measurements from a single researcher for intra-rater reliability. Measurements were compared using Intraclass correlation coefficients and Bland- Altman plots. Results: Results indicated excellent reliability between measurements for both inter-and intra-rater reliability, with slightly better reliability for intra-rater compared with inter-rater reliability. Intraclass correlation coefficients for inter-rater reliability were between 0.77 and 0.98, and 0.94 for intra-rater reliability. Conclusion: Ultrasound measurements of diaphragm thickness can be used to reliably measure diaphragm thickness in mechanically ventilated infants and children. This modality could therefore be used as a reliable outcome measure for future clinical research studies to establish the relationship between ventilator-induced diaphragmatic atrophy and children who are at risk for extubation failure.
Training for transformation : opportunities and challenges for health workforce sustainability in developing a remote clinical training platform
(Frontiers, 2021-04) Muller, Jana; Reardon, Cameron; Hanekom, Susan; Bester, Juanita; Coetzee, Francois; Dube, Kopano; Du Plessis, Elmarize; Couper, Ian
Background: In 2018, Stellenbosch University’s Ukwanda Centre for Rural Health led a faculty initiative to expand undergraduate health professions training to a new site, 9 hours drive from the health sciences campus in the sparsely populated Northern Cape Province of South Africa in the town of Upington. This is part of a faculty strategy to extend undergraduate health sciences training into an under-resourced part of the country, where there is no medical school. During 2019, the first year of implementation, four final year medical students undertook a longitudinal integrated clerkship at this site, while final year students from other programmes undertook short 5-week rotations, with plans for extending rotations and including more disciplines in 2020. The aim of this study was to understand stakeholder perceptions regarding the development of Upington as a rural clinical training site and how this influenced existing services, workforce sustainability and health professions education. Methods: An iterative thematic analysis of qualitative data collected from 55 participants between January and November 2019 was conducted as part of the case study. A constructivist approach to data collection was utilized to explore participants’ perceptions, experiences and understanding of the new training site. Triangulation of data collection and reflexive thematic analysis contributed to the trustworthiness of the data and credibility of the findings. Findings: The perceptions of three key groups of stakeholders are reported: (1) Dr. Harry Surtie Hospital and Academic Programme Managers; (2) Supervising and non-supervising clinical staff and (3) Students from three undergraduate programs of the Faculty. Five themes emerged regarding the development of the site. The themes include the process of development; the influence on the health service; workforce sustainability; a change in perspective and equipping a future workforce. Discussion: This case study provides data to support the value of establishing a rural clinical training platform in a resource constrained environment. The influence of the expansion initiative on the current workforce speaks to the potential for improved capacity and competence in patient management with an impact on encouraging a rural oriented workforce. Using this case study to explore how the establishment of a new rural clinical training site is perceived to influence rural workforce sustainability and pathways, may have relevance to other institutions in similar settings. The degree of sustainability of the clinical training initiative is explored.
