Item Applying staff experiences and expectations of an optimum environment for psychiatric care toward a holistic design of an inpatient psychiatric facility in KZN.(2016) Goosen, Angela.; Ramlall, Suvira.; Horner, Bridget Marian.This research paper consists of three key time lines within the evolution of the inpatient psychiatric facilities: the past (local and international), the present (within Kwa-Zulu Natal), and a move toward an improved design model for KwaZulu Natal which considers therapeutic milieu and the end-user needs. This approach seeks to provide valuable insight toward the development of the built form, and how it has impacted the quality of life of the healthcare users who are detained within these facilities, and those who provide their care and treatment. Throughout history, and still evident today in South Africa, the predominant style of psychiatric institutions, is the asylum style of architecture. The historical asylum model, used the built form as a measure to control, detain and confine the mentally ill who were believed to be deviant individuals who, as Markus (1993:95) describes, brought “chaos into the social order of normal society”. During the 17th and 18th centuries, various architectural models were established, based on different beliefs and ideas of how to treat and house the mentally ill. Based on these differing ideas, the design of psychiatric institutions “occupies an unstable space between prison and hospital” (Markus (1993:130). Towards the 21st century, there has been growing trends toward community based care and therapeutic environments however inpatient facilities within KwaZulu Natal still resemble highly institutional-like environments, which are not conducive to the care and recovery of patients, and the working environment of the staff. The primary research therefore focuses on creating an optimum environment for therapeutic care and patient rehabilitation, based on an understanding of care-giver experiences and expectations of inpatient psychiatric facilities. Based on the theory of salutogenesis and therapeutic environment theory, core themes including one’s functional, social, and psychological needs, have been used to assess the evolution of the built form, and how this can be used to inform future architectural design of Psychiatric Inpatient facilities for acutely mentally ill adult male and female patients.Item Screening for and diagnosing dementia in an elderly residential home population : a validation study.(2014) Ramlall, Suvira.; Pillay, Basil Joseph.; Bhigjee, Ahmed Iqbal.Background: With the projected increase in the elderly population and expected rise in the prevalence of dementia, particularly in low-and-middle-income countries, early case identification is necessary for planning and delivering clinical services. The effectiveness of dementia screening depends on the availability of suitable screening tools with good sensitivity and specificity to confidently distinguish normal age-related cognitive decline from dementia. The aims of this research study were to report on the prevalence of cognitive impairment (dementia and Mild Cognitive Impairment-MCI), and to assess the performance of selected screening tools and a neuropsychological battery of tests in a heterogeneous local population. Methodology A cross-sectional study was conducted in a heterogeneous elderly South African population and consisted of three stages of data collection. In the first stage, cognitive screening measures were administered to a group of 302 participants, aged +60 years, living in a residential facility for the aged. The second stage consisted of a sub-sample of 140 participants who were assessed for cognitive impairment based on the Diagnostic and Statistical Manual of Mental Disorders 4th Edition-Text Revised criteria (DSM-IV-TR). Criteria A and B for Alzheimer’s and Vascular dementia were applied to assign a diagnosis of dementia without reference to aetiology. The participants were also assessed for Mild Cognitive Impairment (MCI), based on the criteria of the International Working Group on Mild Cognitive Impairment. Of the 140 participants in stage two, 117 were administered a neuropsychological battery of tests in the third stage. The influence of demographic variables and the sensitivity, specificity and optimum cut-off scores were determined for the following seven selected screening measures, individually and in combination: the Mini- Mental State Examination (MMSE), Subjective Memory Complaint (SMC), Subjective Memory Complaint Clinical (SMCC), Subjective Memory Rating Scale (SMRS), Deterioration Cognitive Observee (DECO), Subjective Memory Complaint Clinical (SMCC) and the Clock Drawing Test (CDT). The sensitivity and specificity of the neuropsychological tests in the detection of dementia were also determined. Results Eleven (7.9%) dementia and 38 (27.1%) MCI cases were diagnosed. Performance on the screening measures was influenced by race, age and education. Using ROC analyses, the SMCC, MMSE and CDT were found to be moderately accurate in screening for dementia with AUC >.70. Neuropsychological test performance was influenced by the age, gender, race and education level of participants. With the exception of the Digit Span (forward), Digit Span (total), COWAT-A, Narrative Memory Test (delayed recall), Token Test and the Luria Hand Sequence Test, all the neuropsychological test measures displayed significance in distinguishing between the three classification groups (controls, MCI, dementia). Conclusion SMCC’s are valid screening questions as a first level of ‘rule-out’ screening. The MMSE can be included at a second stage of screening at general hospital level and the CDT in specialist clinical settings. Several measures from the neuropsychological battery of tests evaluated have discriminant validity and diagnostic accuracy for the differential diagnosis of cognitive disturbances in an elderly heterogeneous South African population .
