RESUMO

In this article, we review the monitoring and evaluation system that is used to measure the performance of primary healthcare delivered through the district health system and district management teams. We then review some global frameworks, especially linked to the World Health Organization, and look at some of the differences between what is internationally recommended and what we do in South Africa. We end with some recommendations to improve the system.

RESUMO

Background. In a previous article on the impact of COVID-19, the authors compared access to routine health services between 2019 and 2020. While differential by province, a number of services provided, as reflected in the District Health Information System (DHIS), were significantly affected by the pandemic. In this article we explore the extent to which the third and fourth waves affected routine services. Objectives. To assess the extent to which waves 3 and 4 of the COVID-19 pandemic affected routine health services in South Africa, and whether there was any recovery in 2021.Methods. Data routinely collected via the DHIS in 2019, 2020 and 2021 were analysed to assess the impact of the COVID-19 pandemic and extent of recovery. Results. While there was recovery in some indicators, such as number of children immunised and HIV tests, in many other areas, including primary healthcare visits, the 2019 numbers have yet to be reached ­ suggesting a slow recovery and continuing impact of the pandemic. Conclusions. TheCOVID-19 pandemic continued to affect routine health services in 2021 in a number of areas. There are signs of recovery to 2019 levels in some of the health indicators. However, the impact indicators of maternal and neonatal mortality continued to worsen in 2021, and if interventions are not urgently implemented, the country is unlikely to meet the Sustainable Development Goals targets

RESUMO

Articles on teenage pregnancies have been proliferating in both the popular press and the medical media. We analysed data available in the public sector database, the District Health Information System, from 2017 to 2021. During this time, the number of births to young teenagers aged 10 - 14 years increased by 48.7% (from a baseline of 2 726, which is very high by developed-country standards) and the birth rate per 1 000 girls in this age category increased from 1.1 to 1.5. These increases occurred year on year in most provinces. In adolescent girls aged 15 - 19, the number of births increased by 17.9% (from a baseline of 114 329) and the birth rate per 1 000 girls in this age category increased from 49.6 to 55.6. These increases also occurred year on year in a continuous upward trend as well as in all provinces, but at different rates. Generally, rates were higher in the more rural provinces such as Limpopo, Mpumalanga and Eastern Cape than in more urban provinces such as Gauteng and Western Cape. The increases during the past 2 years were particularly large and may be due to disruption of health and school services with decreased access to these as a result of COVID-19. These metrics pose serious questions to society in general and especially to the health, education and social sectors, as they reflect socioeconomic circumstances (e.g. sexual and gender-based violence, economic security of families, school attendance) as well as inadequate health education, life skills and access to health services.

RESUMO

BACKGROUND: The COVID-19 pandemic and responses by governments, including lockdowns, have had various consequences for lives and livelihoods. South Africa (SA) was one of the countries that implemented severely restrictive lockdowns to reduce transmission and limit the number of patients requiring hospitalisation. These interventions have had mixed consequences for routine health services. OBJECTIVES: To assess the impact of COVID-19 and restrictions imposed to limit viral transmission on routine health services in SA. METHODS: Data routinely collected via the District Health Information System in 2019 and 2020 were analysed to assess the impact of the COVID-19 pandemic. RESULTS: Access to public health services between March 2020 and December 2020 was limited in all provinces. However, this was not linear, i.e. not all services in all provinces were similarly affected. Services most severely affected were antenatal visits before 20 weeks, access to contraceptives, and HIV and TB testing. The impact on outcomes was also noticeable, with a measurable effect on maternal and neonatal mortality. CONCLUSIONS: The responses to the COVID-19 pandemic, including different levels of lockdowns, the limitation of health services, lack of staff as a result of COVID-19 infection, and fear and stigma, resulted in a reduction in access to routine health services. However, the picture varies by type of service, province and district, with some faring worse than others. It is important to ensure that routine services are not significantly affected during future COVID-19 waves. This will require careful planning on the part of service providers and optimal communication with patients and communities.

RESUMO

South Africa (SA) is committed to reducing tuberculosis (TB) mortality rates in line with the World Health Organization's End TB Strategy and the Sustainable Development Goal (SDG) targets. From mortality reports released by Statistics South Africa, this study analysed reported TB mortality in SA from 2006 to 2016 to inform our understanding of TB mortality and the development of strategies needed to attain the SDG targets. TB mortality includes all deaths reported to the Department of Home Affairs with TB reported as the underlying cause of death based on the 10th revision of the International Statistical Classification of Diseases and Related Health Problems (ICD-10) definition. Although TB remains the leading cause of death, TB mortality rates in SA have fallen substantially in the past decade. From 2006 to 2016, the number of deaths due to TB plummeted from 76 881 to 29 399 and the proportion of all-cause mortality due to TB more than halved from 13% to <6%. Furthermore, the profile of people dying from TB has changed, with a decrease in the proportion of children aged <15 years, adults of reproductive age (15 - 49) and women, and an increase in the proportion aged ≥50. This change has largely mirrored the overall pattern of deaths in SA, with large decreases in deaths in adults aged 15 - 49, especially women, thought to be because of the scale-up of the antiretroviral treatment programme for HIV. The End TB Strategy target of a 95% reduction in TB mortality by 2035 is achievable in SA. However, sustained effort in high-risk groups together with improved vital registration data are needed to ensure attainment of the target.

RESUMO

AIM: To determine the incidence and types of complications associated with oesophageal foreign body (FB) removal in dogs, as well as to evaluate potential risk factors for the development of complications. METHODS: Clinical records were searched within Animal Emergency Service and Veterinary Specialist Services databases between July 2001 and March 2017. Data were collected regarding signalment, FB type, method of removal, medical management and complications. Follow-up records from the referring veterinarian were then obtained by either phone call or email. RESULTS: A total of 349 FB cases were reviewed. The majority of FBs were bones (77.4%), with Staffordshire Bull Terriers (12.3%) and West Highland White Terriers (9.8%) the most common breeds seen. Complications at the time of FB removal occurred in 20 cases (5.9%), with 14 cases of perforation. Persistent gastrointestinal signs were reported in 4.7% of cases within the initial 72-h period following FB removal and 11.9% cases outside this time period. Respiratory signs such as dyspnoea and coughing were also reported in 8 cases (2.3%), all of which occurred within 72 h after FB removal. Follow-up of at least 1 month was available in 151 cases. Delayed complications occurred in 11 cases (7.3%), with stricture occurring in 4 cases (2.6%); 16 animals were either euthanased (n = 14) or died (n = 2) post-FB removal, resulting in a case fatality rate of 4.6%. CONCLUSION: Use of antacid medications and FB type did not have a statistically significant relationship with complications following FB removal.

RESUMO

This study aimed to assess whether modifying the pitch of a 75° ladder ergometer to vertical had a cardiorespiratory or psychophysical effect on climbing. Nine male participants climbed a ladder ergometer at 75° and subsequently at 90°, adjusted for an equivalent vertical climb rate, completing three climbing bouts at different vertical speeds. One participant dropped out being unable to complete the climb under the 90° condition. Each was monitored for heart rate (HR), V˙O2 and rating of perceived exertion (RPE). Results showed vertical climbing induced higher V˙O2 (mean increase 17.3%), higher HR (mean increase 15.8%), and higher RPE at all speeds and that moving from 75°to vertical exacerbates the effect of speed on the cardiorespiratory response to climbing. This may be explained by increased force production required to maintain balance in a vertical climbing position when the body's centre of mass is not above the feet.

RESUMO

BACKGROUND: Monitoring the prevention of mother-to-child transmission (PMTCT) programme to identify gaps for early intervention is essential as South Africa progresses from prevention to elimination of HIV infection in children. Early infant diagnosis (EID) by an HIV polymerase chain reaction (PCR) test is recommended at 6 weeks of age for all HIV-exposed infants. The National Health Laboratory Service (NHLS) performs the PCR tests for the public health sector and stores test data in a corporate data warehouse (CDW). OBJECTIVES: To demonstrate the utility of laboratory data for monitoring trends in EID coverage and early vertical transmission rates and to describe the scale-up of the EID component of the PMTCT programme. METHODS: HIV PCR test data from 2003 to 2012 inclusive were extracted from the NHLS CDW by year, province, age of infant tested and test result and used to calculate EID coverage and early vertical transmission rates to provincial level. RESULTS: Rapid scale-up of EID over the first decade of the PMTCT programme was evident from the 100-fold increase in PCR tests to 350 000 by 2012. In 2012, 73% of the estimated 270 000 HIV-exposed infants requiring an early PCR were tested and the early vertical transmission rate had fallen to 2.4% as a result of successful implementation of the PMTCT programme. CONCLUSIONS: Laboratory data can provide real time, affordable monitoring of aspects of the PMTCT programme and assist in achieving virtual elimination of paediatric HIV infection in South Africa.

RESUMO

BACKGROUND: South Africa (SA) is committed to achieving the goal of eliminating mother-to-child transmission (MTCT) of HIV by 2015. To achieve this, universal coverage of quality antenatal, labour, delivery and postnatal services for all women has to be attained. Over the past decade, the prevention of mother-to-child transmission (PMTCT) programme has been scaled up to reach all healthcare facilities in the country. However, challenges persist in achieving 100% coverage and access to the programme. OBJECTIVES: We describe the process undertaken by the National Department of Health (NDoH), in collaboration with partners, to develop, implement and monitor a data-driven intervention to improve facility, district, provincial and national PMTCT-related performance. METHODS: Between 2011 and 2013, the NDoH developed and implemented an intervention using data-driven participatory processes to understand facility-level bottlenecks to optimise PMTCT implementation and to scale up priority PMTCT actions nationally. RESULTS: There was remarkable improvement across all key indicators in the PMTCT cascade over the 3 years 2011-2013. Simple monitoring tools such as a visual dashboard and data for action reports were successfully used to improve the performance of the PMTCT programme across SA. MTCT has shown a significant downward trend. CONCLUSIONS: It is feasible to implement district-level, data-driven quality improvement processes at a national scale to improve the performance of the PMTCT programme at the local level.

RESUMO

El estudio del ganglio centinela (GC) en el tratamiento del melanoma requiere una estrecha colaboración entre el cirujano plástico, el dermatólogo, el especialista en Medicina Nuclear y el patólogo. Presentamos un estudio retrospectivo sobre un grupo de 123 pacientes con melanoma primario cutáneo en los que se realizó técnica de biopsia selectiva del gangliocentinela (BSGC) entre diciembre de 1999 y diciembre del 2005 en el Hospital Universitario Cruces en Barakaldo (Bizkaia, España) y describimos la evolución a largo plazo y la relación entre los resultados de la BSGC y los eventos clínicos relevantes durante el seguimiento. Fueron extirpados 294 ganglios centinela; en 15 pacientes el patólogo informó de la presencia de micrometástasis en el GC, desarrollando posteriormente metástasis a distancia el 46,6% de esos pacientes frente a un 19% en aquellos con GC negativo (p=0,021). De los 123 pacientes estudiados, 14 fallecieron por melanoma (11´4%):3 en el primer año de seguimiento, 2 en el segundo, 3 en el tercero, 2 en el cuarto y 2 en el quinto año. Nuestra experiencia confirma que la BSGC es una técnica sencilla y útil para el estadiaje del melanoma por mostrar una tendencia hacia la asociación estadística entre la positividad del GC y un peor pronóstico (AU)


The study of sentinel node (SN) in the management of melanoma requires close collaboration among plastic surgeon, dermatologist, specialist in Nuclear Medicine and pathologist. The authors present a retrospective study in a group of123 patients with primary cutaneous melanoma who consented to sentinel node biopsy (SLNB) between December1999 and December 2005 at the University Hospital Cruces (Barakaldo, Bizkaia, Spain). We describe the long-term evolution and the relation between SLNB results and relevant clinical events during follow-up. We removed 294 sentinel nodes; 15 patients had tumour in the centinela node, subsequently developed distant metastasis in 46.6%, compared with 19% in patients with negative SN (p=0.021). Of the 123 patients studied,14 died of melanoma (11´4%): 3 in the first year of follow up, 2 in the second, 3 in the third, 2 in the fourth and2 in fifth year. We corroborate that the SLNB is an easy technique and useful for staging, showing the statistic relationship between positive SN and bad prognostic (AU)

RESUMO

El paciente gran quemado sigue siendo hoy en día un difícil reto al que se enfrentan múltiples profesionales sanitarios. La elevada mortalidad de estos pacientes se justifica por la severa alteración del estado general que sufren, las múltiples complicaciones que se asocian y por la ausencia de piel válida para cubrir las quemaduras, como sucede en el caso de los quemados de gran extensión. Este último inconveniente se solventa de diferentes maneras, siendo una de las más importantes el cultivo de queratinocitos. En la Unidad de Quemados del Hospital Universitario de Cruces en Baracaldo (Vizcaya), España, iniciamos la aplicación de esta técnica en 2001, con una experiencia acumulada en esta década de 14 pacientes. El objetivo de este artículo es mostrar nuestro protocolo de aplicación del procedimiento para la cobertura de quemados extensos, los criterios de inclusión y la terapéutica pre y postaplicación de las láminas de queratinocitos que empleamos en nuestra Unidad. Así mismo, presentamos las características de los pacientes tratados y nuestra propia experiencia en la aplicación de esta técnica que, a pesar de lograr resultados cada vez más satisfactorios y ser en ocasiones la única alternativa para un paciente extensamente quemado, tiene todavía hoy en día tantos detractores (AU)


The severe burn patient continues being nowadays a difficult challenge which multiple sanitary professionals face. The high mortality of these patients justifies itself by the severe alteration of the general condition, the multiple complications that they suffer and the absence of skin for their coverage, as is the case of extensive burns. This last disadvantage is settled in different ways, being one of the most important the treatment with keratinocytes culture. In the Cruces Universitary Hospital Burn Unit in Baracaldo (Vizcaya), Spain, we began the clinical application of this technique in 2001, with a 14 patients accumulated experience in this period of time. The aim of this article is to show our treatment protocol for the coverage of massive burns, the inclusion criteria and the therapeutics pre and postapplication of keratinocytes. Likewise, we expose the characteristics of the treated patients and our own experience in the application of this technique that, although achieving increasingly satisfactory results, even being sometimes the unique alternative for severe burn patients, still has nowadays many detractors (AU)

RESUMO

OBJECTIVE: To determine if elderly osteopenic patients sustaining an intertrochanteric fracture recover sooner when treated with Lazcano hemiarthroplasty compared with those treated with internal fixation, and whether they can return to their prefracture physical activity level. METHODS: A case-control study was conducted at 1o de Octubre ISSSTE Hospital. Patients over age 70 with intertrochanteric hip fracture and advanced osteopenia were enrolled. The cases were treated with Lazcano hemiarthroplasty and the controls (20 patients) with standard internal fixation (angled plate, DHS system, gamma nail). The comorbid conditions and the prefracture activity level were assessed in both groups. The relation between comorbid conditions and complications was studied and the postoperative activity level of both groups was compared. RESULTS: Thirty patients with these characteristics were included. Ten were cases and 20 were controls. No relation was found between the comorbid conditions and the patients' ability to resume gait postoperatively. Patients treated with hemiarthroplasty walk sooner than those treated with standard internal fixation and have a lower complication rate. CONCLUSIONS: The Lazcano hemiarthroplasty is an excellent choice in the treatment of intertrochanteric fractures in osteopenic patients. Long-term studies with more patients are required to assess the presence of complications.

RESUMO

OBJECTIVE: To determine a reference range for serum cobalamin concentration in healthy cats in Australia using a chemiluminescent enzyme immunoassay and to prospectively investigate the prevalence of hypocobalaminaemia in cats with non-alimentary tract disease. DESIGN: Prospective study measuring serum cobalamin concentrations in clinically healthy cats and cats with non-alimentary tract illness. PROCEDURE: Blood was collected from 50 clinically healthy cats that were owned by staff and associates of Veterinary Specialist Services or were owned animals presented to Creek Road Cat Clinic for routine vaccination. Blood was collected from 47 cats with non-alimentary tract illness presented at either clinic. Serum cobalamin concentration was determined for each group using a chemiluminescent enzyme immunoassay. RESULTS: A reference range for Australian cats calculated using the central 95th percentile in the 50 clinically healthy cats was 345 to 3668 pg/mL. Median serum cobalamin concentration in 47 cats with non-alimentary tract illness (1186 pg/mL; range 117-3480) was not significantly different to the median serum cobalamin of the 50 healthy cats (1213 pg/mL, range 311-3688). Using the calculated reference range one sick cat with non-alimentary tract illness had a markedly low serum cobalamin concentration. CONCLUSION: Although hypocobalaminaemia is uncommon in sick cats with non-alimentary tract illness in Australia, its occurrence in this study warrants further investigation.

RESUMO

Operator field of view is of primary importance for efficient and safe operation of field machines such as tractors, forest harvesting machines, and earthmoving equipment. This research uses a light source with a series of light sensors, and a contour plot of a derived visibility index, to quantify the masking effect of obstructions on the light source and to map the blind areas due to inherent obstructions in the field of view. The described method provides a quantified two-dimensional assessment of the blind areas in the workspace and could be used for rapid assessment of potential limitations in operator visibility for field machines.
