RESUMO

The South African National Department of Health developed a quality improvement (QI) programme to reduce maternal and neonatal mortality and still births. The programme was implemented between 2018 and 2022 in 21 purposively selected public health facilities. We conducted a process evaluation to describe the characteristics and skills of the QI team leaders of well-performing teams. The evaluation was conducted in 15 of the 21 facilities. Facilities were purposively selected and comprised semi-structured interviews with leaders at three time points; reviewing of QI documentation; and 37 intermittently conducted semi-structured interviews with the QI advisors, being QI technical experts who supported the teams. These interviews focused on participants' experiences and perceptions of how the teams performed, and performance barriers and enablers. Thematic data analysis was conducted using Atlas.ti. Variation in team performance was associated with leaders' attributes and skills. However, the COVID-19 pandemic also affected team functioning. Well-performing teams had leaders who effectively navigated COVID-19 and other challenges, who embraced QI and had sound QI skills. These leaders cultivated trust by taking responsibility for failures, correcting members' mistakes in encouraging ways, and setting high standards of care. Moreover, they promoted programme ownership among members by delegating tasks. Given the critical role leaders play in team performance and thus in the outcomes of QI programmes, efforts should focus on leader selection, training, and support.

RESUMO

BACKGROUND: Despite progress, maternal and neonatal mortality and still births remain high in South Africa. The South African National Department of Health implemented a quality improvement (QI) programme, called Mphatlalatsane, to reduce maternal and neonatal mortality and still births. It was implemented in 21 public health facilities, seven per participating province, between 2018 and 2022. METHODS: We conducted a qualitative process evaluation of the contextual and implementation process factors' influence on implementation uptake amongst the QI teams in 15 purposively selected facilities. Data collection included three interview rounds with the leaders and members of the QI teams in each facility; intermittent interviews with the QI advisors; programme documentation review; observation of programme management meetings; and keeping a fieldwork journal. All data were thematically analysed in Atlas.ti. Implementation uptake varied across the three provinces and between facilities within provinces. RESULTS: Between March and August 2020, the COVID-19 pandemic disrupted uptake in all provinces but affected QI teams in one province more severely than others, because they received limited pre-pandemic training. Better uptake among other sites was attributed to receiving more QI training pre-COVID-19, having an experienced QI advisor, and good teamwork. Uptake was more challenging amongst hospital teams which had more staff and more complicated MNH services, versus the primary healthcare facilities. We also attributed better uptake to greater district management support. A key factor shaping uptake was leaders' intrinsic motivation to apply QI methodology. We found that, across sites, organic adaptations to the QI methodology were made by teams, started during COVID-19. Teams did away with rapid testing of change ideas and keeping a paper trail of the steps followed. Though still using data to identify service problems, they used self-developed audit tools to record intervention effectiveness, and not the prescribed tools. CONCLUSIONS: Our study underscores the critical role of intrinsic motivation of team leaders, support from experienced technical QI advisors, and context-sensitive adaptations to maximise QI uptake when traditionally recognised QI steps cannot be followed.

RESUMO

AIM: This study investigates the psychological wellbeing of United Kingdom National Health Service doctors during the Covid-19 pandemic and evaluates how they have been supported managerially. METHOD: A mixed-method sequential study design of online surveys and semi-structured interviews was employed between July-August 2020, with a response rate of 273/300 and 4/4 respectively. The Warwick-Edinburgh Mental Wellbeing Scale (WEMWBS) and Health and Safety Executive Management Standards (HSE MS) were used as measuring tools. The Jobs Demands Resource (JD-R) model and its relation to psychological wellbeing was determined. Survey findings informed semi-structured interviews, coded using thematic analysis. RESULTS: Overall mean WEMWBS, 43.2 (SD = 9.44), was low as was mean managerial support, 2.38 (SD = 0.78). Overall mean clinical demand score was high (2.6 on reverse scale). First year female trainee respondents from frontline specialties were found to have low psychological wellbeing scores. Key correlations were found between high managerial support, low clinical demands and low psychological wellbeing (r > 0.6). Core themes emerged: (1) breakdown of leadership, (2) vulnerability of wellbeing without support, (3) suboptimal navigation through change and (4) poor physical and human resource management. CONCLUSION: Maintaining the psychological wellbeing of doctors requires physical and psychological resources to meet clinical demands and the enhancement of fundamental managerial principles of control, communication, change management and leadership through adversity.

RESUMO

Despite global progress in reducing maternal and neonatal mortality and stillbirths, much work remains to be done to achieve the Sustainable Development Goals. Reports indicate that coronavirus disease (COVID-19) disrupts the provision and uptake of routine maternal and neonatal health care (MNH) services and negatively impacts cumulative pre-COVID-19 achievements. We describe a multipartnered MNH quality improvement (QI) initiative called Mphatlalatsane, which was implemented in South Africa before and during the COVID-19 pandemic. The initiative aimed to reduce the maternal mortality ratio, neonatal mortality rate, and stillbirth rate by 50% between 2018 and 2022. The multifaceted design comprises QI and other intervention activities across micro-, meso-, and macrolevels, and its area-based approach facilitates patients' access to MNH services. The initiative commenced 6 months pre-COVID-19, with subsequent adaptation necessitated by COVID-19. The initial focus on a plan-do-study-act QI model shifted toward meeting the immediate needs of health care workers (HCWs), the health system, and health care managers arising from COVID-19. Examples include providing emotional support to staff and streamlining supply chain management for infection control and personal protection materials. As these needs were addressed, Mphatlalatsane gradually refocused HCWs' and managers' attention to recognize the disruptions caused by COVID-19 to routine MNH services. This gradual reprioritization included the development of a risk matrix to help staff and managers identify specific risks to service provision and uptake and develop mitigating measures. Through this approach, Mphatlalatsane led to an optimization case using existing resources rather than requesting new resources to build an investment case, with a responsive design and implementation approach as the cornerstone of the initiative. Further, Mphatlalatsane demonstrates that agile and context-specific responses to crises such as the COVID-19 pandemic can mitigate such threats and maintain interventions to improve MNH services.

RESUMO

BACKGROUND: Gauteng province, with 26.3% of South Africa's population, is the commercial and industrial powerhouse of the country. During the first epidemic wave in 2020, Gauteng accounted for 32.0% of South Africa's reported COVID-19 cases. AIM: The aim of this study was to describe the health system response to the COVID-19 pandemic during the first epidemic wave in Gauteng province and to explore the perspectives of key informants on the provincial response. MATERIAL AND METHODS: Using an adapted Pandemic Emergency Response Conceptual Framework, this was a qualitative case study design consisting of 36 key informant interviews and a document analysis. We used thematic analysis to identify themes and sub-themes from the qualitative data. RESULTS: Our case study found that Gauteng developed an innovative, multi-sectoral and comprehensive provincial COVID-19 response that aimed to address the dual challenge of saving lives and the economy. However, the interviews revealed multiple perspectives, experiences, contestations and contradictions in the pandemic response. The COVID-19 pandemic exposed and amplified the fragilities of existing systems, reflected in the corruption on personal protective equipment, poor data quality and inappropriate decisions on self-standing field hospitals. Rooted in a chronic under-investment and insufficient focus on the health workforce, the response failed to take into account or deal with their fears, and to incorporate strategies for psychosocial support, and safe working environments. The single-minded focus on COVID-19 exacerbated these fragilities, resulting in a de facto health system lockdown and reported collateral damage. The key informants identified missed opportunities to invest in primary health care, partner with communities and to include the private health sector in the pandemic response. CONCLUSION: Gauteng province should build on the innovations of the multi-sectoral response to the COVID-19 pandemic, while addressing the contested areas and health system fragilities.

RESUMO

BACKGROUND: Use of liquid plasma (LP) has been reported as early as the mid 1930s. Unlike fresh-frozen plasma (FFP), LP is maintained at 1 to 6°C for up to 40 days after collection and processing. Despite its approved use by the US Food and Drug Administration, the coagulation profile of LP is incompletely described. In this study we evaluate the coagulation profile of LP stored up to 30 days. STUDY DESIGN AND METHODS: LP was prepared by removing plasma from nonleukoreduced whole blood within 24 hours of collection. Three LP units from each ABO group were collected and stored at 1 to 6°C. Plasma aliquots were obtained at Postcollection Days 1 to 5, 10, 15, 20, 25, and 30 and then stored at -70°C. Each aliquot was tested for prothrombin time, activated partial thromboplastin time, and other coagulation and fibrinolytic factors. RESULTS: There was a significant decrease in Factor (F)V, FVII, FVIII, von Willebrand factor (VWF), protein S (PS) activity, and endogenous thrombin potential on Day 15 compared with Day 1. No significant difference was observed for PS antigen, D-dimer, or thrombin-antithrombin complex. At least 50% activity of all measured factors was noted on Day 15, compared to Day 1. Considerable heterogeneity was observed between the different blood groups for FVII, FVIII, and VWF. CONCLUSION: These data demonstrate that LP maintains at least 50% of factor activity and thrombin-generating capacity up to 15 days of refrigerated storage. It may be more appropriate to limit LP storage and supplement with FFP when used for management of massively bleeding patients.

RESUMO

Milestones represent the essential knowledge, skills, and attitudes required for the practice of a medical discipline. Defining these milestones for each medical specialty has become a focus for the American Council of Graduate Medical Education (ACGME). Practitioners of Apheresis Medicine come from a variety of medical specialties making it challenging to establish the essential educational milestones for all. The American Society for Apheresis (ASFA) has an interest in promoting standards of excellence for Apheresis Medicine. ASFA's Physician's Curriculum Content Committee is a group of physician educators in the field of Apheresis Medicine, both donor and therapeutic, from across the United States, who have met regularly for several years to discuss the appropriate educational milestones in Apheresis training. The committee members teach residents and fellows from Pathology, Transfusion Medicine, Hematology/Oncology, Nephrology and other specialties. In this document, we have outlined the basic set of Apheresis milestones required in the ACGME defined competency areas of Patient Care and Medical Knowledge. We have also recommended methods of evaluation and estimated the time necessary for the acquisition of these cognitive and behavioral elements.

RESUMO

We previously compared changes in individual protein abundance between the proteomes of GS-NS0 cell lines with varying rates of cell-specific recombinant monoclonal antibody production (qMab). Here we extend analyses of our proteomic dataset to statistically determine if particular cell lines have distinct functional capabilities that facilitate production of secreted recombinant Mab. We categorized 79 proteins identified by mass spectrometry according to their biological function or location in the cell and statistically compared the relative abundance of proteins in each category between GS-NS0 cell lines with varying qMab. We found that the relative abundance of proteins in ER chaperone, non-ER chaperone, cytoskeletal, cell signaling, metabolic, and mitochondrial categories were significantly increased with qMab. As the GS-NS0 cell line with highest qMab also had an increased intracellular abundance of unassembled Mab heavy chain (HC), we tested the hypothesis that the increased ER chaperone content was caused by induction of an unfolded protein response (UPR) signaling pathway. Immunoblot analyses revealed that spliced X-box binding protein 1 (XBP1), a marker for UPR induction, was not detectable in the GS-NS0 cells with elevated qMab, although it was induced by chemical inhibitors of protein folding. These data suggest that qMab is functionally related to the abundance of specific categories of proteins that together facilitate recombinant protein production. We infer that individual cells within parental populations are more functionally equipped for high-level recombinant protein production than others and that this bias could be used to select cells that are more likely to achieve high qMab.

RESUMO

The relationship between spot volume and variation for all protein spots observed on large format 2D gels when utilising silver stain technology and a model system based on mammalian NSO cell extracts is reported. By running multiple gels we have shown that the reproducibility of data generated in this way is dependent on individual protein spot volumes, which in turn are directly correlated with the coefficient of variation. The coefficients of variation across all observed protein spots were highest for low abundant proteins which are the primary contributors to process error, and lowest for more abundant proteins. Using the relationship between spot volume and coefficient of variation we show it is necessary to calculate variation for individual protein spot volumes. The inherent limitations of silver staining therefore mean that errors in individual protein spot volumes must be considered when assessing significant changes in protein spot volume and not global error.

RESUMO

CONTEXT: Transfusion-related acute lung injury (TRALI) is a syndrome that includes dyspnea, hypotension, bilateral pulmonary edema, and fever. TRALI is the third leading cause of transfusion-related mortality, but it is probably underdiagnosed and underreported. OBJECTIVE: To determine if blood products from a frequent plasma donor, whose blood product was implicated in a fatal case of TRALI, caused symptoms of TRALI in other recipients of her plasma. DESIGN, SETTING, AND PARTICIPANTS: Retrospective chart review (conducted from November 2000 through April 2001) of 50 patients who received blood components within 2 years (October 1998 through October 2000) from a donor linked to a transfusion-related fatality. MAIN OUTCOME MEASURE: Occurrence of mild/moderate (dyspnea with fever, chills, hypotension, and/or hypoxemia) or severe (acute pulmonary edema or need for mechanical ventilation) reaction associated with transfusion. RESULTS: Superimposed illness prevented assessment of TRALI in 14 patients. Of the 36 patient charts that could be reviewed, 7 mild/moderate reactions were reported in 6 patients (16.7%) and 8 severe reactions were reported in 8 patients (22.2%). Of 5 patients who received multiple transfusions from the same donor, 2 experienced 2 reactions: one had 2 mild/moderate reactions and the other had both a mild/moderate and a severe reaction. While 5 of the 7 mild/moderate reactions were reported to the hospital transfusion service, only 2 of the 8 severe reactions were reported. Only 2 reactions (1 mild/moderate and 1 severe) were reported to the regional blood collection facility. CONCLUSIONS: TRALI was frequently underdiagnosed and underreported in recipients of blood products from a donor whose blood products may have caused TRALI in several transfusion recipients. Clinical education and awareness of this often-overlooked diagnosis are imperative for appropriate prevention and treatment.
