Impact of the South African Mental Health Care Act No. 17 of 2002 on regional and district hospitals designated for mental health care in KwaZulu- Natal

Background. The South African Mental Health Care Act (the Act) No. 17 of 2002 stipulated that regional and district hospitals be designated to admit, observe and treat mental health care users (MHCUs) for 72 hours before they are transferred to a psychiatric hospital. Methods. Medical managers in 49 ‘designated’ hospitals in KwaZulu-Natal (KZN) were surveyed on infrastructure, staffing, administrative requirements and mental health care user case load pertaining to the Act for the month of July 2009. Results. Thirty-six (73.4%) hospitals responded to the survey; 30 (83.3%) stated that the Act improved mental health care for MHCUs through the protection of their rights, provision of least restrictive care, and reduction of discrimination; 10 (27.8%) had a psychiatric unit and, of the remaining 26 hospitals, 11 (30.6%) had general ward beds dedicated for psychiatric admissions; 16 (44.4%) had some form of seclusion facility; and 24 (66.7%) provided an outpatient psychiatric service. Seventy-six per cent of admissions were involuntary or assisted. Thirteen of the 32 (40.6%) state psychiatrists in KZN were employed at 8 of these hospitals. Designated hospitals expressed dissatisfaction with the substantial administrative load required by the Act. The Review Board had not visited 29 (80.6%) hospitals in the preceding 6 months. Conclusion. Although ‘designated’ hospitals admit and treat assisted and involuntary MHCUs, they do so against a backdrop of inadequate infrastructure and staff, a high administrative load, and a low level of contact with Review Boards

A telepsychiatry model to support psychiatric outreach in the public sector in South Africa

The access of rural Mental Health Care Users in South Africa to specialist psychiatrists and quality mental health care is currently sub-optimal. Health professionals and planners working in psychiatry lack a well-defined and feasible outreach model to facilitate the delivery of services to remote and rural areas. In response to this challenge, a three-year action research telepsychiatry study was undertaken by the Departments of Psychiatry and TeleHealth at the University of KwaZulu-Natal, to develop a telepsychiatry outreach model based on local research and international evidence. The Model draws on needs and infrastructure assessments of the designated psychiatric hospitals in the province, a review of the published international evidence on telepsychiatry and videoconference-based education, and an evaluation of local clinical and educational telepsychiatry implementations in KwaZulu-Natal. The Model proposed is “virtual”, i.e. not bound to provincial or district referral patterns, aims not to add to the burden onthe current workforce and is intended to be integrated into psychiatry outreach services and policy. The Model should be subjected to in situ testing for validation and implementation. It is hoped that an implementation of this Model will improve the access of Mental Health Care Users to specialist psychiatry care.Keywords: Videoconferencing; Psychiatry; Model; Telepsychiatry; South Afric

Forensic telepsychiatry : a possible solution for South Africa?

Objective: South Africa has a shortage of facilities and psychiatrists to assess adjudicative competence of prisoners awaiting assessment under sections 77 to 79 of the Criminal Procedures Act of 1977. Various solutions have been proposed by the Department of Health. The recent linking of a Magistrate’s court and a prison by videoconferencing offers the opportunity to implement a forensic telepsychiatry service. The literature on forensic telepsychiatry for assessment of adjudicative competence was reviewed. Method: The electronic databases, PubMed, Scopus, Cinahl and Google Scholar were searched for papers on forensic telepsychiatry. The inclusion criterion was papers reporting the use of videoconferencing for assessment of adjudicative competence or for assessment for referral out of the judicial system, by psychiatrists or psychologists. Results: 411 papers were found of which 13, published between 1997 and 2008 were relevant. The use of videoconferencing for forensic psychiatric assessment was reported from four countries. The courts in those jurisdictions have accepted the use of videoconferencing for assessment and no successful appeals have been mounted on the basis of the use of videoconferencing for assessment. User satisfaction has not been reported for assessing adjudicative competence. Forensic telepsychiatry has been found to be cost effective, improve access to scarce specialist skills and reduce transport of prisoners under guard to hospitals or psychiatrists to prisons. Conclusion: There is nothing in the literature to suggest that a forensic telepsychiatry service is not feasible in South Africa and a pilot project is being planned.Keywords: Videoconferencing; Telemedicine; Forensic psychiatry; South Afric

Full left ventricular coverage is essential for the accurate quantification of the area- at- risk by T1 and T2 mapping

T2-weighted cardiovascular magnetic resonance (CMR) using a 3-slice approach has been shown to accurately quantify the edema-based area-at-risk (AAR) in ST-segment elevation myocardial infarction (STEMI). We aimed to compare the performance of a 3-slice approach to full left ventricular (LV) coverage for the AAR by T1 and T2 mapping and MI size. Forty-eight STEMI patients were prospectively recruited and underwent a CMR at 4 ± 2 days. There was no difference between the AARfull LV and AAR3-slices by T1 (P = 0.054) and T2-mapping (P = 0.092), with good correlations but small biases and wide limits of agreements (T1-mapping: N = 30, R2 = 0.85, bias = 1.7 ± 9.4% LV; T2-mapping: N = 48, R2 = 0.75, bias = 1.7 ± 12.9% LV). There was also no significant difference between MI size3-slices and MI sizefull LV (P = 0.93) with an excellent correlation between the two (R2 0.92) but a small bias of 0.5% and a wide limit of agreement of ±7.7%. Although MSI was similar between the 2 approaches, MSI3-slices performed poorly when MSI was <0.50. Furthermore, using AAR3-slices and MI sizefull LV resulted in ‘negative’ MSI in 7/48 patients. Full LV coverage T1 and T2 mapping are more accurate than a 3-slice approach for delineating the AAR, especially in those with MSI < 0.50 and we would advocate full LV coverage in future studies

Depression in older adults: prevalence and risk factors in a primary health care sample

BACKGROUND: Depression in the geriatric population has been identified as a significant problem in view of the associated negative outcomes regarding poor functioning, increased perception of poor health and increased utilisation of medical services. Significantly associated with increased morbidity and mortality, depression has been found to be an independent cause of disability as well as adding to disability due to primary physical illnesses. Early identification and treatment of depression reduces medical costs and lessens caregiver burden. Epidemiological data and prevalence rates of geriatric depression in Africa are limited, although such data are vital to mobilise and plan government mental health initiatives aimed at screening and early intervention. OBJECTIVE: To determine the prevalence of depression and associated clinical and socio-demographic factors amongst older adult patients attending a primary health care clinic in the Ethekwini District in Kwa-Zulu Natal, South Africa. METHODS: The 15-item Geriatric Depression Scale and a socio-demographic questionnaire were administered in English to 255 geriatric outpatients, randomly selected, at a local community clinic in Durban. DATA ANALYSIS: Data were analysed using SPSS version 23®. Descriptive statistics were used to summarise the sample demographics and response rate and non-parametric statistics were used to test for associations and differences. RESULTS: A Cronbach’s alpha for the GDS was calculated (p = 0.793). Some 40% of participants screened positive for depression. Female gender, widowhood and a negative subjective health status rating were significantly associated with depression and marriage appeared to be protective (p < 0.001). Participants with a poor subjective health rating were 21 times more likely to be depressed and widowhood conferred an almost fourfold increased risk of being depressed, with widows at greater risk than widowers. No association between depression and specific medical conditions was identified. CONCLUSION: There is a high rate of undetected depression among the elderly attending a local primary health care clinic with widowhood and poor subjective health being strong predictors of mood disorders. The findings warrant replication in bigger samples.DHE

Robust adaptive immune response against Babesia microti infection marked by low parasitemia in a murine model of sickle cell disease.

The intraerythrocytic parasite Babesia microti is the number 1 cause of transfusion-transmitted infection and can induce serious, often life-threatening complications in immunocompromised individuals including transfusion-dependent patients with sickle cell disease (SCD). Despite the existence of strong long-lasting immunological protection against a second infection in mouse models, little is known about the cell types or the kinetics of protective adaptive immunity mounted following Babesia infection, especially in infection-prone SCD that are thought to have an impaired immune system. Here, we show, using a mouse B microti infection model, that infected wild-type (WT) mice mount a very strong adaptive immune response, characterized by (1) coordinated induction of a robust germinal center (GC) reaction; (2) development of follicular helper T (TFH) cells that comprise ∼30% of splenic CD4+ T cells at peak expansion by 10 days postinfection; and (3) high levels of effector T-cell cytokines, including interleukin 21 and interferon γ, with an increase in the secretion of antigen (Ag)-specific antibodies (Abs). Strikingly, the Townes SCD mouse model had significantly lower levels of parasitemia. Despite a highly disorganized splenic architecture before infection, these mice elicited a surprisingly robust adaptive immune response (including comparable levels of GC B cells, TFH cells, and effector cytokines as control and sickle trait mice), but higher immunoglobulin G responses against 2 Babesia-specific proteins, which may contain potential immunogenic epitopes. Together, these studies establish the robust emergence of adaptive immunity to Babesia even in immunologically compromised SCD mice. Identification of potentially immunogenic epitopes has implications to identify long-term carriers, and aid Ag-specific vaccine development. © 2018 by The American Society of Hematology

Effect of remote ischaemic conditioning on infarct size and remodelling in ST-segment elevation myocardial infarction patients: the CONDI-2/ERIC-PPCI CMR substudy

The effect of limb remote ischaemic conditioning (RIC) on myocardial infarct (MI) size and left ventricular ejection fraction (LVEF) was investigated in a pre-planned cardiovascular magnetic resonance (CMR) substudy of the CONDI-2/ERIC-PPCI trial. This single-blind multi-centre trial (7 sites in UK and Denmark) included 169 ST-segment elevation myocardial infarction (STEMI) patients who were already randomised to either control (n = 89) or limb RIC (n = 80) (4 × 5 min cycles of arm cuff inflations/deflations) prior to primary percutaneous coronary intervention. CMR was performed acutely and at 6 months. The primary endpoint was MI size on the 6 month CMR scan, expressed as median and interquartile range. In 110 patients with 6-month CMR data, limb RIC did not reduce MI size [RIC: 13.0 (5.1–17.1)% of LV mass; control: 11.1 (7.0–17.8)% of LV mass, P = 0.39], or LVEF, when compared to control. In 162 patients with acute CMR data, limb RIC had no effect on acute MI size, microvascular obstruction and LVEF when compared to control. In a subgroup of anterior STEMI patients, RIC was associated with lower incidence of microvascular obstruction and higher LVEF on the acute scan when compared with control, but this was not associated with an improvement in LVEF at 6 months. In summary, in this pre-planned CMR substudy of the CONDI-2/ERIC-PPCI trial, there was no evidence that limb RIC reduced MI size or improved LVEF at 6 months by CMR, findings which are consistent with the neutral effects of limb RIC on clinical outcomes reported in the main CONDI-2/ERIC-PPCI trial

The Effect of Organisational Factors in Motivating Healthcare Employees: A Systematic Review

Healthcare employee motivation is a key concept in the achievement of efficient,effective and good quality healthcare delivery. In this paper a systematic review of primary data from the UK, Europe, Africa and Asia was conducted to consolidate the available evidence on the effect of organisational factors on healthcare employee motivation. Because healthcare delivery is highly labour intensive, it must be acknowledged that human resources are extremely critical in the drive for healthcare organisations to deliver on their organisational goals. The organisational factors which were identified as having a great effect on healthcare employee motivation can be divided into financial and non-financial factors. Remuneration was identified as a strong extrinsic factor, while conducive working conditions, increased responsibilities and appreciation from the communities in which they serve were identified as strong intrinsic factors. Even though there is a cultural aspect to motivation, remuneration, managerial support and career advancement are core factors that affect all healthcare professionals irrespective of country. Many of the factors that were observed in the literature as affecting motivation can be addressed by an overhaul of the reward strategy of healthcare organisations
