Post-traumatic stress disorder symptoms following a head injury: does amnesia for the event influence the development of symptoms?

BACKGROUND: There is controversy as to whether PTSD can develop following a brain injury with a loss of consciousness. However, no studies have specifically examined the influence of the memories that the individuals may or may not have on the development of symptoms. AIMS: To consider how amnesia for the traumatic event effects the development and profile of traumatic stress symptoms. METHOD: Fifteen hundred case records from an Accident and Emergency Unit were screened to identify 371 individuals with traumatic brain injury who were sent questionnaires by post. The 53 subsequent valid responses yielded three groups: those with no memory (n = 14), untraumatic memories (n = 13) and traumatic memories (n = 26) of the index event. The IES-R was used as a screening measure followed by a structured interview (CAPS-DX) to determine caseness and provide details of symptom profile. RESULTS: Groups with no memories or traumatic memories of the index event reported higher levels of psychological distress than the group with untraumatic memories. Ratings of PTSD symptoms were less severe in the no memory groups compared to those with traumatic memories. CONCLUSIONS: Psychological distress was associated with having traumatic or no memories of an index event. Amnesia for the event did not protect against PTSD; however, it does appear to protect against the severity and presence of specific intrusive symptoms.

Who cares for the patient with head injury now?

OBJECTIVE: A recent report on head injury management from the Royal College of Surgeons of England suggests that surgeons are unsuited to the inpatient care of head injuries (ICHI) and should hand over responsibility entirely to neurosurgeons and accident and emergency (A&E) specialists. This prompted a survey of A&E consultants to establish their opinions on the current and future practice of head injury care. METHODS: Questionnaires were sent to consultant members of the British Association for Accident and Emergency medicine. Of a possible 256 A&E departments from Great Britain and Ireland with over 20 000 annual new attenders 206 (80%) replied. RESULTS: General surgeons contribute to ICHI for adults in 107 of 206 hospitals (52%) compared with orthopaedic surgeons in 73 of 206 (35%) and A&E consultants in 71 of 206 (34%). There was frequent criticism that surgeons are uninterested in head injury care. Fifty nine units (30%) commented on the lack of neurosurgery beds and difficulties experienced in getting patients accepted. Few hospitals seem to have well integrated rehabilitation or follow up services targeted at head injury. One in six patients with head injury admitted to a general hospital or observation ward remain after 48 hours and one in 20 stay beyond one week. Of the 132 A&E units without responsibility for ICHI 54 (41%) either wish to take on this responsibility or are willing to do so if the necessary resources are first put in place. The perceived net revenue cost required to allow 67 A&E units to take on ICHI is about 12.5 million pounds per year. This does not include the cost of further care after 48 hours, follow up or rehabilitation. CONCLUSION: Only one third of A&E units at present have even part of the ICHI role recommended in the RCS report; another third are prepared to accept a new role if training and resources are provided and support is forthcoming from other specialists to take over the care after 48 hours; the remaining third are unwilling to accept responsibility for ICHI.

CPR '98: a practical multimedia computer-based guide to cardiopulmonary resuscitation for medical students.

This paper describes an initiative to build a multimedia computer-based teaching package for cardiopulmonary resuscitation. The project resulted from a perceived gap in the undergraduate medical curriculum allied to concern from medical students. The software application was designed to be networked and used as an adjunct to taught life support courses for undergraduate medical students. The package comprises tutorials and test questions in basic and advanced life support. It incorporates sound, video, graphics and animation to illustrate the techniques involved and is distributed on CD ROM for the PC. The content is based on the 'Advanced Life Support Manual', produced by the Resuscitation Council (UK) and incorporates all changes to the guidelines made during 1997 and 1998. The basic life support section has been networked locally, and has been tested on more than 60 third year medical students attending a local basic life support course. It was found that students who used the package performed significantly better in theoretical assessments than those who did not.

Effect of Strathclyde police initiative "Operation Blade" on accident and emergency attendances due to assault.

OBJECTIVE: To review assault victim attendance at the accident and emergency department of Glasgow Royal Infirmary before and after a police initiative to curb knife carrying and tackle violent assaults ("Operation Blade"). METHODS: Assault victim attendance was reviewed for the month before the implementation of Operation Blade and for one month a year later. The number of victims requiring treatment in the resuscitation room for stab wounds before, during, and after Operation Blade was also reviewed as a crude indicator of the frequency of serious assaults in the city. RESULTS: There were no significant differences in the nature or number of assault victims attending this hospital one year after Operation Blade compared with the month before its implementation. Operation Blade reduced the number of serious stabbings for a period of 10 months, but subsequently numbers surpassed those prevailing before its implementation. CONCLUSIONS: Any attempt to combat this complex and multifactorial problem must be addressed through a combined public health and education initiative in conjunction with regular press and police campaigns to achieve a sustained effect.

Critical analysis of an accident and emergency ward.

OBJECTIVES: To describe the work, both qualitatively and quantitatively, of an accident and emergency (A&E) ward, and discuss some of the advantages and disadvantages associated with this ward. METHODS: An observational study was carried out of all patients admitted to the A&E ward of Glasgow Royal Infirmary from 1 January 1992 to 31 December 1992. Epidemiological and management data were collected for all patients admitted. RESULTS: There were 2460 admissions, of which 69% were related to trauma and 45% to head injury; 47% of the patients had consumed alcohol before admission. Accidental trauma was the commonest reason for admission (57%), followed by assault (33%). Ninety two per cent of admissions stayed for less than 3 d, but 33% of the workload was spent on a small number of patients admitted for longer than 7 d. CONCLUSIONS: This A&E ward presents a significant workload, and some of its most serious problems lie with those patients who stay longer than 72 h. The safe and effective use of the ward depends upon it being well resourced, along with the department it serves.

Inadvertent subclavian artery puncture in an intravenous drug abuser.

Arterial complications from inadvertent arterial puncture in intravenous drug abusers are well recognised. Most reports describe injury to the femoral artery with occasional reports of brachial and radial artery injury. A case of subclavian artery injury is described in this paper, and the pathophysiology and treatment of intraarterial drug injection discussed.

Management of minor head injuries in the accident and emergency department: the effect of an observation ward.

The management of 483 patients presenting with minor head injury to the accident and emergency (A&E) departments of two Scottish hospitals was studied prospectively. Such patients comprised 5.7 and 3.9% of the total attendances to each department. Of the 277 patients assessed in the former department, 83 (30%) fulfilled at least one of the currently accepted criteria for recommending admission to hospital and 49 (17.7%) patients were actually admitted. Patients in whom head injury was not the principal reason for admission were excluded from the study. In the same time period the second department dealt with 206 patients with minor head injury, 49 (24%) of whom had criteria for admission. However, significantly fewer, 10 (4.9%) patients, were actually admitted. The major relevant factor when comparing the two departments was the existence in the former of an observation ward. These results support the view that easy access to hospital beds is a major determinant of management in patients presenting with minor head injury to the A&E department and may be more influential than clinical findings.

The introduction of automatic blood pressure monitoring to an accident & emergency resuscitation room.

Machines for automatic non-invasive blood pressure (BP) monitoring are increasingly available in British accident and emergency departments. Our department recently acquired two machines with this capability for use in the resuscitation room. This provided us with an opportunity to compare the speed and frequency of automatic BP recording with the previously used manual method. We found no significant difference in either the median time to the first recording of BP or in the median number of documented recordings in the first hour. However, the overall frequency of BP recording did show a statistically significant increase. We conclude that automation alone does not improve standard practice in this area greatly.

Unplanned re-attendance in the accident and emergency department.

The notes of patients who re-attended the Accident and Emergency Department with a problem for which they had already been seen and treated were reviewed over a five-week period. Such patients comprised 2.5% of total attendances. The commonest reason for re-attendance was persistent pain following an injury and of such patients, about a half required a significant change in management. It was estimated that two-thirds of re-attendances were unavoidable. Twenty patients were admitted following re-attendance, and of these, two had serious medical conditions which were missed on initial presentation. The role of senior Accident and Emergency doctors is discussed in the light of these findings.

Electrocardiograph interpretation by junior doctors.

The object of this study was to assess the ability of junior doctors in the accident and emergency department to detect electrocardiographic (ECG) abnormalities. The ECG's performed in this department were monitored over a 4 week period. The initial diagnosis by the accident and emergency doctor was compared with the report from the cardiologist on 126 ECG's which showed abnormalities. The error rate was 19.8%. Of those abnormalities which were graded as clinically significant only 2 (4.4%) were missed. The danger of missing acute changes is emphasized and proposals discussed which may reduce their frequency.

The general practitioner's use and expectations of an accident and emergency department.

In an attempt to establish what the general practitioner expects from an accident and emergency department, and how closely the service provided correlates with that view, a 12-point questionnaire was sent to the general practitioners in the Glasgow Royal Infirmary catchment area. Out of the 61.2% of general practitioners who replied, the majority wish to have responsibility for their own patients for conditions which are neither accidents nor emergencies. There is less agreement as to how much should be done within an accident and emergency department and on the appropriate modes of referral and communication between the general practitioner and the hospital service. Further consultation and cooperation are necessary to interpret and resolve these differences.

An evaluation of open scalp wounds.

A retrospective study of 661 adult patients with open scalp wounds attending the Accident and Emergency Department of Glasgow Royal Infirmary, Glasgow, Scotland, was performed. Detailed information was recorded about history, nature of open wounds ('contused' or 'incised'), wound exploration and radiological findings. The commonest cause of injury was assault (40%), followed by falls (34%). Half of the patients had been drinking alcohol. The majority of scalp wounds were 'contused' (84%) resulting equally from assaults and falls; 'incised' wounds (16%) were more commonly due to assault. Although division of the occipitofrontalis aponeurosis was infrequent (18%), most (78%) of the skull fractures occurred in this group. Wound exploration detected nine fractures not evident on skull X-rays. To maximise fracture detection rate, careful wound exploration should be an important adjunct to skull radiography and, in particular, division of the occipitofrontalis aponeurosis should alert the casualty officer to the likelihood of a skull fracture.
