BackgroundTo date, delirium prevalence and incidence in acute hospitals has been estimated from pooled findings of studies performed in distinct patient populations.ObjectiveTo determine delirium prevalence across an acute care facility.DesignA point prevalence study.SettingA large tertiary care, teaching hospital.Patients311 general hospital adult inpatients were assessed over a single day. Of those, 280 had full data collected within the study's time frame (90%).MeasurementsInitial screening for inattention was performed using the spatial span forwards and months backwards tests by junior medical staff, followed by two independent formal delirium assessments: first the Confusion Assessment Method (CAM) by trained geriatric medicine consultants and registrars, and, subsequently, the Delirium Rating Scale-Revised-98 (DRS-R98) by experienced psychiatrists. The diagnosis of delirium was ultimately made using DSM-IV (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition) criteria.ResultsUsing DSM-IV criteria, 55 of 280 patients (19.6%) had delirium versus 17.6% using the CAM. Using the DRS-R98 total score for independent diagnosis, 20.7% had full delirium, and 8.6% had subsyndromal delirium. Prevalence was higher in older patients (4.7% if <50 years and 34.8% if >80 years) and particularly in those with prior dementia (OR=15.33, p<0.001), even when adjusted for potential confounders. Although 50.9% of delirious patients had pre-existing dementia, it was poorly documented in the medical notes. Delirium symptoms detected by medical notes, nurse interview and patient reports did not overlap much, with inattention noted by professional staff, and acute change and sleep-wake disturbance noted by patients.ConclusionsOur point prevalence study confirms that delirium occurs in about 1/5 of general hospital inpatients and particularly in those with prior cognitive impairment. Recognition strategies may need to be tailored to the symptoms most noticed by the detector (patient, nurse or primary physician) if formal assessments are not available.
Abstract:This paper reports on a qualitative descriptive study that explored student midwives experiences of the Objective Structured Clinical Examination assessment process for obstetric emergencies within a university setting. The development of fundamental clinical skills is an important component in preparing students to meet the responsibilities of a midwife. There is an international concern that the transfer of midwifery education into universities may impact on the development of midwifery clinical skills. Objective Structured Clinical Examinations (OSCEs) have the potential to promote integration and consolidation of skills prior to clinical placement. Twenty six students (n=36) from two midwifery programmes (BSc and Higher Diploma) participated in four focus groups and Burnard's (2006) framework was used for data analysis. Three main themes emerged following analysis: Preparation for the OSCE assessment, the OSCE process and Learning through simulating practice. Preparation for the OSCE's which included lectures, demonstrations, and practice of OSCE's facilitated by lecturers and by the students themselves, was considered central to the process. Learning via OSCEs was perceived to be more effective in comparison to other forms of assessment and prepared students for clinical practice. Positive aspects of the process and areas for improvement were identified. Using OSCE's increased the depth of learning for the students with the steps taken in preparation for the OSCE's proving to be a valuable learning tool. This study adds to the evidence on the use of OSCE's in midwifery education
Background The frequency of full syndromal and subsyndromal delirium is understudied. Aims We conducted a point prevalence study in a general hospital. Method Possible delirium identified by testing for inattention was evaluated regarding delirium status (full/subsyndromal delirium) using categorical (Confusion Assessment Method (CAM), DSM-IV) and dimensional (Delirium Rating Scale-Revised-98 (DRS-R98) scores) methods. Results In total 162 of 311 patients (52%) screened positive for inattention. Delirium was diagnosed in 55 patients (17.7%) using DSM-IV, 52 (16.7%) using CAM and 58 (18.6%) using DRS-R98⩾12 with concordance for 38 (12.2%) individuals. Subsyndromal delirium was identified in 24 patients (7.7%) using a DRS-R98 score of 7-11 and 41 (13.2%) using 2/4 CAM criteria. Subsyndromal delirium with inattention (v. without) had greater disturbance of multiple delirium symptoms. Conclusions The point prevalence of delirium and subsyndromal delirium was 25%. There was modest concordance between DRS-R98, DSM-IV and CAM delirium diagnoses. Inattention should be central to subsyndromal delirium definitions.
The benefits and challenges associated with internship in midwifery are apparent, particularly when students' are contending with two geographically distant sites. Support mechanisms and suggestions for improvements are considered.
Summary:Objective: To explore the attitudes of first time mothers towards antenatal education from the perspective of attenders and non-attenders.Design: A qualitative approach was utilised using focus group interviews to collect the data.Setting: The study was conducted in one Local Health Office Area of the Health Service Executive-South East, Ireland.Participants: A purposive sample of first time mothers were interviewed to explore the area of antenatal education. These women included both attenders and non-attenders at antenatal education.Key conclusions: The findings suggest there are many strengths, weaknesses, opportunities and barriers to antenatal education. Implications for practice: Some fundamental issues related to the provision and delivery of antenatal education were identified.
