“…None were diagnostic accuracy studies and so did not report sensitivity, specificity, predictive values, likelihood ratios, diagnostic odds ratios or receiver operating characteristic curves. Some studies included one or more comparator groups 90,95,97,99,101,102,107 which took the form of a healthy control population or patients with another psychiatric diagnosis. The effectiveness of CT or MRI neuroimaging in healthy subjects or non-psychotic patients was not relevant to this review, so this information was not extracted.…”

HTA on CD is currently free of charge worldwide.The website also provides information about the HTA Programme and lists the membership of the various committees. HTA NIHR Health Technology Assessment ProgrammeT he Health Technology Assessment (HTA) Programme, part of the National Institute for Health Research (NIHR), was set up in 1993. It produces high-quality research information on the effectiveness, costs and broader impact of health technologies for those who use, manage and provide care in the NHS. 'Health technologies' are broadly defined as all interventions used to promote health, prevent and treat disease, and improve rehabilitation and long-term care. The research findings from the HTA Programme directly influence decision-making bodies such as the National Institute for Health and Clinical Excellence (NICE) and the National Screening Committee (NSC). HTA findings also help to improve the quality of clinical practice in the NHS indirectly in that they form a key component of the 'National Knowledge Service'. The HTA Programme is needs-led in that it fills gaps in the evidence needed by the NHS. There are three routes to the start of projects. First is the commissioned route. Suggestions for research are actively sought from people working in the NHS, the public and consumer groups and professional bodies such as royal colleges and NHS trusts. These sugges...

BackgroundThe use of neuroimaging modalities in psychiatry has been evaluated in several studies. The vast majority seem to suggest that neuroimaging may be overutilised in psychiatry. There is a significant constraint on availability and cost related to neuroimaging of patients at general state medical facilities. The routine use of computerised tomography (CT) scanning is thus questioned.MethodsA retrospective analysis was undertaken of all psychiatric inpatients who had CT scans performed from 01 January 2011 to 31 December 2012. Demographic data, mental state examination, physical examination findings, substance use and diagnosis upon admission were recorded. The relationship between these variables and CT scan findings was analysed.ResultsA total of 897 admissions were retrospectively analysed. One hundred and three patients had documented CT scan imaging. In total, 17 of the 23 patients with abnormal findings on CT scan were found to be psychotic (74.0%). The remaining 26.0% included depression and dementia. There was no statistically significant difference between the normal and abnormal CT scan groups with regard to gender, age, family history, substance use and physical examination. The majority (65.2%) had cerebral atrophy and/or cerebral calcifications. A smaller group of other documented findings was noted.ConclusionsSelective indications and clinical markers may be utilised in order to justify brain imaging studies rather than performing them routinely. That being true, a multicentre study with a larger sample size is indicated to further improve the statistical significance and assist in formulating a more concrete guideline for neuroimaging of psychiatric patients.

BackgroundMany neurological conditions manifest with psychiatric symptoms and may be misdiagnosed. Structural neuroimaging, that is, computerised tomography (CT) and magnetic resonance imaging (MRI), can aid in the diagnosis or exclusion of these conditions. Magnetic resonance imaging is preferable in this regard, but is more expensive and less readily available than CT. The indications for requesting MRI in the clinical psychiatric setting remain poorly defined. All published literature on the clinical utility of neuroimaging in Africa is on CT scans.AimThe aim of this study was to describe the clinical characteristics and MRI findings in a cohort of patients presenting with psychiatric symptoms.SettingA specialist psychiatric training hospital, Townhill Hospital, in Pietermaritzburg, KwaZulu-Natal.MethodsA retrospective chart review of all patients who underwent MRI between 01 October 2010 and 31 June 2016 was done. Magnetic resonance imaging findings were correlated with socio-demographic and clinical information, including psychiatric diagnosis, indication for MRI imaging and effect on clinical management.ResultsFifty-three MRIs were performed. Thirty-three (62%) were abnormal. Patients with HIV, neurocognitive disorders, chronic mental illness and involuntary admission were more likely to have abnormal scans (83%, p = 0.089; 80%, p = 0.496; 71%, p = 0.089 and 79%, p = 0.021, respectively). The findings of 54% of abnormal MRIs (24% of all MRIs performed) resulted in referral to other disciplines. No statistically significant associations were found with socio-demographic or clinical factors.ConclusionAbnormalities on MRI scans in mentally ill patients were common and a quarter of patients required referral to other disciplines. Further studies are required to clarify the clinical utility of MRI in patients with psychiatric illness, which could assist in the development of a guide for the rational use of this modality in a resource-constrained environment.
