Based on increasing evidence that even mild closed head injury (CHI) can cause considerable neural damage throughout the brain, we hypothesized that mild CHI will disrupt the complex cerebral networks concerned with oculomotor and upper-limb visuomotor control, resulting in impaired motor function. Within 10 days following mild CHI (Glasgow Coma Scale(More)
IMPORTANCE Patients with chest pain represent a high health care burden, but it may be possible to identify a patient group with a low short-term risk of adverse cardiac events who are suitable for early discharge. OBJECTIVE To compare the effectiveness of a rapid diagnostic pathway with a standard-care diagnostic pathway for the assessment of patients(More)
OBJECTIVES The purpose of this study was to determine whether a new accelerated diagnostic protocol (ADP) for possible cardiac chest pain could identify low-risk patients suitable for early discharge (with follow-up shortly after discharge). BACKGROUND Patients presenting with possible acute coronary syndrome (ACS), who have a low short-term risk of(More)
AIM To describe the characteristics of adult frequent attenders presenting to a major urban emergency department during a twelve month period. METHODS A retrospective study was performed of all frequent attenders (presenting ten of more times during twelve months) to the Emergency Department (ED) at Christchurch Hospital. RESULTS The proportion of(More)
Increasing patient numbers, changing demographics and altered patient expectations have all contributed to the current problem with 'overcrowding' in emergency departments (EDs). The problem has reached crisis level in a number of countries, with significant implications for patient safety, quality of care, staff 'burnout' and patient and staff(More)
AIMS To test the hypothesis that triaging certain emergency department (ED) patients through a rapid assessment clinic (RAC) improves the waiting times, and times in the department, for all patients presenting to the emergency department. METHODS For ten weeks an additional nurse and doctor were rostered. On the odd weeks, these two staff ran a RAC and on(More)
AIMS Emergency Departments (EDs) worldwide are facing a crisis from overcrowding--a common perception exists that inappropriate use of the ED is the major contributing factor. This study aims to examine the concept of 'inappropriate' ED attendances in relation to the Emergency Department at New Zealand's Christchurch Hospital. It specifically seeks to(More)
AIM To review the current epidemiology of patients with deliberate self-poisoning presenting to Christchurch Emergency Department, and to compare this with 1996, 1992, and 1989 data. METHODS A retrospective analysis of computer and case records over the twelve-month period of 1999 was conducted and compared with published data from 1996,1992 and 1989. (More)
AIM To describe the effect of a pilot national telephone advice service (Healthline) on a public hospital emergency department. METHODS We prospectively gathered information from the Christchurch Hospital Emergency Department (ED) computer- and non-computer-based information systems, for a six-month period during the operation of Healthline. We compared(More)
In this longitudinal study, we compare the effects of different types of relocation and level of affectedness on the incidence and relapse of mood and anxiety symptom treatments identified by publicly funded care or treatment one year before and one and two years after the '2011 Christchurch earthquake' in New Zealand. Based on a subset of Christchurch(More)
