The views of family physicians on National Health Insurance in Gauteng Province, South Africa.

BACKGROUND:  Universal health coverage (UHC) improves national health outcomes while addressing social inequalities in access to quality healthcare services. The district health system (DHS) is critical to the success of UHC in South Africa through the National Health Insurance (NHI) scheme. Family physicians (FPs), as champions of primary care, are central to the DHS operation and implementation of NHI. METHODS:  This was a qualitative exploratory study that used semi-structured interviews to explore FPs views and engagement on NHI policy and implementation in their districts. Ten FPs were included through purposive sampling. RESULTS:  Most of the FPs interviewed were not engaged in either policy formulation or strategic planning. The NHI bill was seen as a theoretical ideology that lacked any clear plan. Family physicians expressed several concerns around corruption in governmental structures that could play out in NHI implementation. Family physicians felt unsupported within their district structures and disempowered to engage in rollout strategies. The FPs were able to provide useful solutions to health system challenges because of the design of their training programmes, as well as their experience at the primary care level. CONCLUSION:  Healthcare governance in South Africa remains located in national and provincial structures. Devolution of governance to the DHS is required if NHI implementation is to succeed. The FPs need to be engaged in NHI strategies, to translate plans into actionable objectives at the primary care level.Contribution: This study highlights the need to involve FPs as key actors in implementing NHI strategies at a decentralised DHS governance level.

Vertiginous dizziness: A primary care approach.

Dizziness is an extremely common, yet complex neurological symptom that reflects a disturbance of normal balance perception and spatial orientation. Dizziness is a non-specific, catch-all term commonly used by patients to describe a wide array of symptoms, including a sensation of motion, weakness, light-headedness, unsteadiness, emotional upset and depression. The national 1-year prevalence of dizziness is around 50%, accounting for 4% of emergency department presentations and 1% of primary care consultations in South Africa. This article will focus on a diagnostic approach to the most common cause of dizziness (vertigo).

Guiding the emerging primary care researcher: A report of research capacity-building workshop.

There is an escalating interest in research capacity building across the globe. Research is an integral part of the continuous improvement process, clinical decision making and health system strengthening and should be embedded into the health system. The South African Family Practice Journal editorial team held a workshop on 19 August 2022 at the 24th National Family Practitioners Congress in Cape Town, with the aim of supporting primary care clinicians in their development from early-career researchers to established clinician-scientists. Small group and plenary discussions yielded valuable insights into the lived experiences of early career researchers and highlighted critical action areas to build the landscape of clinician-led research in the South African context.Contribution: This article contributes to current literature by providing insight into the lived experiences of early-career researchers and explores opportunities for research capacity-building.

The use of vagal manoeuvres in narrow complex tachyarrhythmias in primary care.

Supraventricular tachydysrhythmias (SVTs) are a common presenting complaint, with a national prevalence of 3/1000 persons. While most commonly stable, prolonged paroxysms can deteriorate into haemodynamically unstable subtypes or ventricular dysrhythmias. Early recognition with appropriate management is critical to reducing the morbidity associated with this condition. The American Heart Association holds that vagal manoeuvres are a first-line therapy in the management algorithm of stable SVTs. However, they state that no clear recommendations can be made around which manoeuvre to use, highlighting that future research should examine the efficacy and safety profiles of the various manoeuvres. In the South African primary care setting, clinicians must be at the forefront of pragmatic management strategies in the face of resource limitations, such as the unavailability of adenosine - a second-line therapy when vagal manoeuvres fail. In this article, we begin with a case study and review the literature around vagal manoeuvres.

Opinion: The use of point-of-care sonography in primary care: An ethical perspective.

The use of point-of-care ultrasound (PoCUS) is fast becoming a global standard of care. World over, training programmes are embracing the use of PoCUS to improve patient care, reduce risks to patients and reduce the burden of unnecessary referrals and investigations. The South African setting is particularly amenable to the benefits of this diagnostic modality to improve healthcare delivery to rural and marginalised populations. However, as with any technological advancements, the use of PoCUS is also not immune to deleterious consequences and patient harm from overdependence and over-zealous uptake. Family physicians, as the champions of primary care, should take the lead to ensure the effective and proper use of PoCUS in rural and primary care settings through advocacy, training and accreditation of clinicians to safely harness the benefits of PoCUS and minimise harm.

Comparison of curvilinear-array (microconvex) and phased-array transducers for ultrasonography of the lungs in dogs.

OBJECTIVES: To compare the use of curvilinear-array (microconvex) and phased-array transducers for ultrasonographic examination of the lungs in dogs. ANIMALS: 13 client-owned dogs with left-sided congestive heart failure. PROCEDURES: In a prospective methods comparison study, 24 ultrasonographic examinations of the lungs (4 sites/hemithorax) were performed with both curvilinear-array and phased-array transducers at 3 clinical time points. Two observers independently assessed the number of B lines (scored per site and in total), number of sites strongly positive for B lines (ie, those with > 3 B lines/site), and image quality (scored on a 5-point scale). Analyses included assessment of interobserver agreement with κ analysis, comparison of quality scores between transducers with mixed-effects modeling, and investigation of agreement and bias for B-line data and quality scores between transducers with Passing-Bablok regression. RESULTS: Interobserver agreement for total B-line scores and number of strong-positive sites was excellent (κ > 0.80) for both transducers. There was no evidence of analytic bias for the number of B lines or strong-positive sites between transducers. Interobserver agreement for image quality scores was moderate (κ, 0.498 and 0.517 for the curvilinear-array and phased-array transducers, respectively). Both observers consistently assigned higher-quality scores to curvilinear-array images than to phased-array images. CONCLUSIONS AND CLINICAL RELEVANCE: Results indicated both curvilinear-array (microconvex) and phased-array transducers can be used by experienced sonographers to obtain diagnostic ultrasonographic images of the lungs in dogs with acute or resolving left-sided congestive heart failure and suggested the former transducer may be preferred, particularly to aid identification of anatomic landmarks for orientation.

Focused ultrasound of the caudal vena cava in dogs with cavitary effusions or congestive heart failure: A prospective, observational study.

INTRODUCTION: Ultrasonographic indices of the inferior vena cava are useful for predicting right heart filling pressures in people. OBJECTIVES: To determine whether ultrasonographic indices of caudal vena cava (CVC) differ between dogs with right-sided CHF (R-CHF), left-sided CHF (L-CHF), and noncardiac causes of cavitary effusion (NC). MATERIALS AND METHODS: 113 dogs diagnosed with R-CHF (n = 51), L-CHF (30), or NC effusion (32) were enrolled. Seventeen of the R-CHF dogs had pericardial effusion and tamponade. Focused ultrasound was performed prospectively to obtain 2-dimensional and M-mode subxiphoid measures of CVC maximal and minimal size (CVCmax and CVCmin), CVCmax indexed to aortic dimension (CVC:Ao), and CVC collapsibility index (CVC-CI). Variables were compared between study groups using Kruskal-Wallis and Dunn's-Bonferroni testing, and receiver operating characteristics curves were used to assess sensitivity and specificity. RESULTS: All sonographic CVC indices were significantly different between R-CHF and NC dogs (P < 0.001). Variables demonstrating the highest diagnostic accuracy for discriminating R-CHF versus NC were CVC-CI <33% in 2D (91% sensitive and 96% specific) and presence of hepatic venous distension (84% sensitive and 90% specific). L-CHF dogs had higher CVC:Ao and lower CVC-CI compared to NC dogs (P = 0.016 and P = 0.043 in 2D, respectively) but increased CVC-CI compared to the R-CHF group (P < 0.001). CONCLUSIONS: Ultrasonographic indices of CVC size and collapsibility differed between dogs with R-CHF compared to NC causes of cavitary effusions. Dogs with L-CHF have CVC measurements intermediate between R-CHF and NC dogs.

Utility of point-of-care lung ultrasound for monitoring cardiogenic pulmonary edema in dogs.

BACKGROUND: Point-of-care lung ultrasound (LUS) is an effective tool to diagnose left-sided congestive heart failure (L-CHF) in dogs via detection of ultrasound artifacts (B-lines) caused by increased lung water. HYPOTHESIS/OBJECTIVES: To determine whether LUS can be used to monitor resolution of cardiogenic pulmonary edema in dogs, and to compare LUS to other indicators of L-CHF control. ANIMALS: Twenty-five client-owned dogs hospitalized for treatment of first-onset L-CHF. METHODS: Protocolized LUS, thoracic radiographs (TXR), and plasma N-terminal pro-B-type natriuretic peptide were performed at hospital admission, hospital discharge, and recheck examinations. Lung ultrasound findings were compared between timepoints and to other clinical measures of L-CHF. RESULTS: From time of hospital admission to discharge (mean 19.6 hours), median number of LUS sites strongly positive for B-lines (>3 B-lines per site) decreased from 5 (range, 1-8) to 1 (range, 0-5; P < .001), and median total B-line score decreased from 37 (range, 6-74) to 5 (range, 0-32; P = .002). Lung ultrasound indices remained improved at first recheck (P < .001). Number of strong positive sites correlated positively with respiratory rate (r = 0.52, P = .008) and TXR edema score (r = 0.51, P = .009) at hospital admission. Patterns of edema resolution differed between LUS and TXR, with cranial quadrants showing more significant reduction in B-lines compared to TXR edema score (80% vs 29% reduction, respectively; P = .003). CONCLUSIONS AND CLINICAL IMPORTANCE: Lung ultrasound could be a useful tool for monitoring resolution of pulmonary edema in dogs with L-CHF.

Long-term management of congestive heart failure secondary to mitral stenosis in a ring-tailed lemur (Lemur catta).

CASE DESCRIPTION: A 15-year-old sexually intact female ring-tailed lemur (Lemur catta) was evaluated for a heart murmur and progressive radiographic cardiomegaly. CLINICAL FINDINGS: The lemur was clinically normal at the time of initial evaluation. Results of transthoracic echocardiography performed when the animal was anesthetized indicated mitral valve stenosis and severe left atrial dilation. Three months later, signs of left-sided congestive heart failure (CHF; coughing, exercise intolerance, and tachypnea) were observed and confirmed by the presence of radiographic pulmonary edema. TREATMENT AND OUTCOME: Medical treatment that consisted of aspirin, benazepril, furosemide, pimobendan, spironolactone, and ultimately torsemide in lieu of furosemide successfully controlled the lemur's clinical signs for 33 months after the development of CHF. Euthanasia was then elected on the basis of perceived poor quality of life because tachypnea became refractory to progressively higher dosages of diuretic. Necropsy confirmed mitral stenosis with severe left atrial dilation and chronic pulmonary congestion. CLINICAL RELEVANCE: The present report described the long-term medical management of CHF secondary to mitral stenosis in a lemur. Mitral stenosis was suspected to be a congenital defect, similar to the cause of mitral stenosis reported for dogs and cats, rather than to be an acquired change in association with rheumatic heart disease as commonly occurs for people. The lemur's CHF was well managed for 33 months with treatment, including pimobendan, which was well tolerated.

Evaluation of dose-response effects of short-term oral prednisone administration on clinicopathologic and hemodynamic variables in healthy dogs.

OBJECTIVE: To determine whether a dose-response relationship exists between short-term oral prednisone administration and common clinicopathologic variables, cardiovascular biomarkers, and systolic arterial blood pressure (SAP) in healthy dogs. ANIMALS: 8 healthy Beagles. PROCEDURES: Dogs underwent five 5-day experiments (no prednisone treatment [control condition] and prednisone administration at 0.5, 1, 2, and 4 mg/kg, PO, q 24 h), with a 9-day washout period between protocols. Analyses performed before and after treatments included a CBC, serum biochemical analysis, and determination of SAP, fractional excretion of electrolytes, urine protein-to-creatinine ratio, glomerular filtration rate (GFR), serum N-terminal pro B-type natriuretic peptide (NT-proBNP) and plasma cortisol concentrations, and plasma renin activity. Linear mixed-effects modeling was used to compare changes in variables from baseline (day 1 for the same experiment) among treatment conditions. RESULTS: Changes in serum glucose concentration and GFR were significantly greater after administration of prednisone at 4 mg/kg than for the control condition. Fractional excretion of sodium was decreased from baseline when dogs received 0.5, 1, or 4 mg of prednisone/kg, compared with results for the control condition. Several expected changes in clinicopathologic values were observed after prednisone administration at any dose. Changes in serum NT-proBNP concentration, plasma renin activity, and SAP did not differ from changes for the control condition at any prednisone dose. CONCLUSIONS AND CLINICAL RELEVANCE: Oral prednisone administration did not affect SAP, NT-proBNP concentration, or measures of renin-angiotensin-aldosterone system activation in healthy laboratory-housed dogs but was associated with relative increases in GFR and serum glucose concentration.
