Laser doppler assessment of gastric mucosal blood flow in normals and its relationship to the systemic activity of growth peptides in healing and non healing gastric ulcers.

Thesis (M.Med.Sc.)-University of Natal, Durban, 1999.The pattern of mucosal blood flow in normal human stomachs, and benign gastric ulcers was assesed with laser Doppler flowmetry and the relationship between a single determination of ulcer blood flow and the systemic level of growth factors was investigated. A significant ascending gradient in mucosal blood flow from the antrum to fundus was demonstrated. Different levels of cellular activity in the regions of the stomach may explain this gradient. In the gastric ulcers that healed on standard medical therapy mucosal blood flow was significantly increased in comparison to normal stomachs. In the ulcers that were refractory to standard medical therapy mucosal blood flow was significantly lower than in normal stomachs and healing ulcers. Higher systemic levels of the growth factor bFGF were demonstrated in healing ulcers compared to non-healing ulcers. Gastric mucosal blood flow can increase in response to the increased metabolic demands of healing, however impairment of this response may be an important factor preventing healing of benign gastric ulcers. It would appear that non-healing of gastric ulcers can be predicted at initial diagnosis by reduced peri-ulcer gastric mucosal blood flow and low blood levels of bFGF

Trauma quality improvement: The Pietermaritzburg Metropolitan Trauma Service experience with the development of a comprehensive structure to facilitate quality improvement in rural trauma and acute care in KwaZulu-Natal, South Africa

Improving the delivery of efficient and effective surgical care in rural South Africa is a mammoth task bedevilled by conflict between the stakeholders, who include rural doctors, surgeons, ancillary staff, researchers, educators and administrators. Management training is not part of most medical school curricula, yet as they progress in their careers, many clinicians are required to manage a health system and find the shift from caring for individual patients to managing a complex system difficult. Conflict arises when management-type interventions are imposed in a top-down manner on surgical staff suspicious of an unfamiliar field of study. Another area of conflict concerns the place of surgical research. Researchers are often accused of not being sufficiently focused on or concerned about the tasks of service delivery. This article provides an overview of management theory and describes a comprehensive management structure that integrates a model for health systems with a strategic planning process, strategic planning tools and appropriate quality metrics, and shows how the Pietermaritzburg Metropolitan Trauma Service in KwaZulu-Natal Province, South Africa, successfully used this structure to facilitate and contextualise a diverse number of quality improvement programmes and research initiatives in the realm of rural acute surgery and trauma. We have found this structure to be useful, and hope that it may be applied to other acute healthcare systems

Developing a multi-faceted approach to improving and uplifting trauma care in the periphery.

Doctor of Philosophy in General Surgery. University of KwaZulu-Natal, Medical School 2013.Introduction Rural trauma care in South Africa is under resourced and the quality of rural trauma care appears to be uneven. This project aimed to assess the quality of rural trauma care in Sisonke Health District and to develop targeted quality improvement programmes to improve it. Methodology A strategic planning methodology consisting of a situational analysis, planning synthesis and implementation was used in the project and was integrated with a health system’s model of inputs, process and outcome to provide a structured overview of the whole process. A number of academic constructs from fields outside of health care were used to analyse the quality of care and to develop targeted quality improvement programmes. Results The table below summarises the results of this project by placing each of the published papers in this thesis into the integrated grid. The various tools that were adopted to assist with the project included error theory and quality metrics for trauma and acute surgery. These are also situated within the grid. Analysis of the inputs of rural trauma care revealed that there were major deficits in terms of the human resources available to manage the large burden of trauma seen in rural hospitals. Analysis of the process revealed deficits in the transfer process and the quality of documentation and observation of trauma patients in our system. Analysis of the outcomes revealed a high incidence of error associated with rural trauma care and poor outcomes for a number of conditions such as burns. Synthesis and Implementation involved the development of a number of strategies and a review of their efficacy. These included a surgical outreach programme, restructured morbidity and mortality meetings, error-awareness training and the use of tick-box clerking sheets. The impact of these various programmes was mixed. The surgical outreach programme was successful at delivering surgical care in the districts but less successful at transferring surgical skills to rural staff. The morbidity and mortality meetings, and the errorawareness training changed the culture of the institution and increased the understanding of the danger of error. The tick-box initiative revealed how difficult it is to change human behaviour. A number of audits have suggested that there is a general improvement in the quality of care. This has resulted in improved outcomes for the management of penetrating abdominal trauma and burns care. Conclusion Rural trauma care has many deficits and these translate into poor outcomes. Addressing these deficits is difficult and requires a multi -faceted approach. Undertaking quality improvement programmes in an ad hoc manner may be counter-productive and using a structured systematic approach may allow planners to contextualise their interventions. Currently trying to increase the inputs and resources available for rural trauma care is difficult and most of the intervention should aim at refining and improving the process of care. A number of projects have emerged from this thesis

Analysis of 5 years of morbidity and mortality conferences in a metropolitan South African trauma service

Background. Since 2008 the Pietermaritzburg Metropolitan Trauma Service (PMTS) has run a structured, self-reporting, metropolitan morbidity and mortality conference (MMC). In 2012 a hybrid electronic medical registry (HEMR) was introduced to capture routine data and to generate reports on morbidity and mortality. This paper reviews our experience in setting up a metropolitan MMC and compares the quality of the reported morbidity data from the pre- and post-HEMR era.Methods. We compared data from the MMC before and after the introduction of the HEMR to audit the impact of these meetings on the reporting and analysis of surgical morbidity and mortality in our service.Results. During the 4-year period from 2008 to 2011, a total of 208 MMCs were held. A total of 10 682 patients were admitted by the PMTS during that period, of whom 87% were males, and the mean age was 26 years. Penetrating trauma accounted for 40.9% (4 344/10 628) of the total workload. A total of 432 (4.1%) morbidities were identified. Of these, 36.6% (158) were related to human error, 32% (138/432) were related to surgical pathologies and the remaining 31.9% (136/432) were related to systemic diseases. There was an exponential increase in the reporting of morbidity each year. The total in-hospital mortality was 3% (358/10 682). Following the introduction of the HEMR, from 2012 to 2014, 6 217 patients were admitted. A total of 1 314 (21.1%) adverse events and 315 (5.1%) deaths were recorded by the HEMR. The adverse events were divided into 875 ‘pathology-related’ morbidities and 439 ‘error-related’ morbidities.Conclusions. The development of the MMC led to increased reporting of morbidity and mortality. The introduction of the HEMR resulted in a dramatic improvement in the capturing of morbidity and mortality data, suggesting that a paper-based self-reporting system tends to underestimate morbidity. Over one-third of all morbidities were related to human error. Common morbidities have been identified

Emergency operation for penetrating thoracic trauma in a metropolitan surgical service in South Africa

IntroductionThis audit examines our total experience with penetrating thoracic trauma. It reviews all the patients who were brought alive to our surgical service and all who were taken directly to the mortuary. The group of patients who underwent emergency operation for penetrating thoracic trauma is examined in detail.MethodologyA prospective trauma registry is maintained by the Pietermaritzburg Metropolitan Complex. This database was retrospectively interrogated for all patients requiring an emergency thoracic operation for penetrating injury from July 2006 till July 2009. A retrospective review of mortuary data for the same period was undertaken to identify patients with penetrating thoracic trauma who had been taken to the forensic mortuary.ResultsOver the 3-year period July 2006 to July 2009, a total of 1186 patients, 77 of whom were female, were admitted to the surgical services in Pietermaritzburg with penetrating thoracic trauma. There were 124 gunshot wounds and 1062 stab wounds. A total of 108 (9%) patients required emergency operation during the period under review. The mechanism of trauma in the operative group was stab wounds (n = 102), gunshot wound (n = 4), stab with compass (n = 1), and impalement by falling on an arrow (n = 1). Over the same period 676 persons with penetrating thoracic trauma were taken to the mortuary. There were 135 (20%) gunshot wounds of the chest in the mortuary cohort. The overall mortality for penetrating thoracic trauma was 541 (33%) of 1603 for stab wounds and 135 (52%) of 259 for gunshot wounds of the chest. Among the 541 subjects with stab wounds from the mortuary cohort, there were 206 (38%) with cardiac injuries. In the emergency operation group there were 11 (10%) deaths. In 76 patients a cardiac injury was identified. The other injuries identified were lung parenchyma bleeding (n = 12) intercostal vessels (n = 10), great vessels of the chest (n = 6), internal thoracic vessel (n = 2), and pericardial injury with no myocardial injury (n = 2). Most patients reached the hospital within 60 minutes of sustaining their injury. A subset of 12 patients had much longer delays of 12 to 24 hours. Surgical access was via median sternotomy in 56 patients and lateral thoracotomy in 52. The overall mortality for penetrating cardiac trauma in our series was 217 (76%) of 282.ConclusionsPenetrating thoracic trauma has a high mortality rate of 30% for subjects with stab wounds and 52% for those with gunshot wounds. Less than a quarter of patients with a penetrating cardiac injury reach the hospital alive. Of those who do and who are operated on, about 90 percent will survive. Other injuries necessitating emergency operation are lung parenchyma, intercostal vessels and internal thoracic vessels, and great vessels of the thorax. Gunshot wounds of the thorax remain more lethal than stab wounds

Tick-box admission forms improve the quality of documentation of surgical emergencies, but have limited impact on clinical behaviour

Introduction. We used modern error theory to develop a tick-box admission form for emergency surgical patients. The tick boxes were designed to actively direct care down appropriate clinical algorithms by encouraging staff to make decisions based on recorded clinical data.Objective. To audit the effect of these tick-box forms on the quality of documentation and of the resuscitation process.Methods. We designed and implemented a standardised tick-box admission form, and audited its impact by comparing 100 emergency surgical admissions before the intervention with 100 thereafter. We assessed the quality of the documentation in both groups and analysed the effect of use of the tick-box admission form and the decision nodes on the clinical behaviour of the admitting clinicians.Results. The introduction of standardised tick-box admission forms dramatically improved the quality of documentation of acute surgical admissions. However, the impact of the decision nodes on clinical behaviour was less obvious. We demonstrated a tendency to cognitive dissonance in that, even though clinicians recorded abnormal physiological data, they did not consistently interpret this information correctly.Conclusions. Although the use of tick-box admission forms improves the quality of documentation, the impact on clinical behaviour is less certain. Quality improvement is a multifactorial endeavour, and without a pervasive culture of patient safety, tick-boxes alone may well be ineffective

Self-expanding metal stent placement for oesophageal cancer without fluoroscopy is safe and effective

Background. Self-expanding metal stents (SEMS) are widely used to palliate patients with oesophageal cancer. Placement is usually done under endoscopic and fluoroscopic guidance. We have developed an exclusively endoscopic technique to deploy these stents. This article documents the technique and periprocedural experience.Patients and methods. All patients who had SEMS placement for oesophageal cancer at Grey’s Hospital, Pietermaritzburg, South Africa, over a 5-year period (2007 - 2011) were reviewed. Stenting was performed without radiological guidance using the technique documented in this article. At endoscopy, the oesophageal lesion was identified, dilated over a guidewire if necessary, and a partially covered stent was passed over the wire and positioned and deployed under direct vision. Data were captured from completed procedure forms and included demographics, tumour length, the presence of fistulas, stent size and immediate complications.Results. A total of 480 SEMS were inserted, involving 453 patients, of whom 43 required repeat stenting. There were 185 female patients (40.8%) and 268 male patients (59.2%). The mean age was 60 years (range 38 - 101). There were 432 black patients (95.4%), 15 white patients (3.3%) and 6 Indian patients (1.3%). The reasons for palliative stenting were distributed as follows: age >70 years n=95 patients, tumour >8 cm n=142, tracheo-oesophageal fistula (TOF) n=29, and unspecified n=170. One patient refused surgery, and one stent was placed for a post-oesophagectomy leak. Repeat stenting was for stent migration (n=15), tumour overgrowth (n=26) and a blocked stent and a stricture (n=1 each). Complications were recorded in six cases (1.3%): iatrogenic TOF (n=2), false tracts (n=3) and perforation (n=1). All six were nevertheless successfully stented. There was no periprocedural mortality.Conclusion. The endoscopic placement technique described is a viable and safe option with a low periprocedural complication rate. It is of particular use in situations of restricted access to fluoroscopic guidance
