Characteristics and outcome among patients suffering in-hospital cardiac arrest in monitored and non-monitored areas.

AIM: To describe the characteristics and outcome among patients suffering in-hospital cardiac arrest in relation to whether the arrest took place in a ward with monitoring facilities. METHODS: All patients who suffered an in-hospital cardiac arrest during a 4-year period in Sahlgrenska Hospital, Göteborg, Sweden and in whom resuscitative efforts were attempted, were prospectively recorded and described in terms of characteristics and outcome. RESULTS: Among 557 patients, 292 (53%) had a cardiac arrest in wards with monitoring facilities. Those in a monitored location more frequently had a confirmed or possible acute myocardial infarction (AMI) as judged to be the cause of arrest (P < 0.0001), and the arrest was witnessed more frequently (96 vs. 79%; P < 0.0001). Ventricular fibrillation/tachycardia was observed more often as initial arrhythmia in monitored wards (56 vs. 44%; P = 0.006). The median interval between collapse and first defibrillation was 1 min in monitored wards and 5 min in non-monitored wards (P < 0.0001). Among patients with arrest in monitored wards 43.2% were discharged alive compared with 31.1% of patients in non-monitored wards (P = 0.004). Cerebral performance category (CPC-score) at discharge was somewhat better among survivors in monitored wards. CONCLUSION: In a Swedish University Hospital 47% of in-hospital cardiac arrests in which resuscitation was attempted took place in wards without monitoring facilities. These patients differed markedly from those having arrest in wards with monitoring facilities in terms of characteristics, interval to defibrillation and outcome. A shortening of the interval between collapse and defibrillation in these patients might increase survival even further.

Is there a difference between women and men in characteristics and outcome after in hospital cardiac arrest?

AIM: To describe the characteristics and outcome among patients suffering from an in-hospital cardiac arrest in women and men. METHODS: All patients who suffered an in-hospital cardiac arrest during a 4 year period in Sahlgrenska Hospital Göteborg, Sweden, where the cardiopulmonary resuscitation (CPR) team was called, were recorded and described prospectively in terms of characteristics and outcome. RESULTS: There were 557 patients suffering in-hospital cardiac arrest in whom the CPR-team was alerted. Among them, 217 (39%) were women. Women differed from men having a lower prevalence of earlier myocardial infarction, angina pectoris, renal disease and a higher prevalence of rheumatic disease. In terms of aetiology of the cardiac arrest, 47% men and 48% women were judged to have had a confirmed or possible AMI. More men than women were found in ventricular fibrillation/ventricular tachycardia (VF/VT) (57 vs. 41%; P<0.001), whereas more women were found in pulseless electrical activity (30 vs. 15%; P<0.0001). Cerebral performance categories (CPC)-score at discharge did not differ between men and women. Among women, 36.4% survived to discharge as compared with 38.0% among men (NS). Survival from VF/VT was 64.3% in women and 52.7% in men (NS). When correcting for dissimilarities at baseline, the adjusted odd ratio for being discharged alive from hospital among women as compared with men was 1.66 (95% confidence limit 1.06-2.62; P=0.028). CONCLUSION: Thirty nine percent of patients suffering in-hospital cardiac arrest for whom the CPR-team was alerted, were women. Women were less frequently found in VF/VT than men. After correcting for dissimilarities at baseline, female gender was associated with a small improvement in survival.

[Improved survival after in-hospital cardiac arrest].

Internationally, survival among patients suffering in-hospital cardiac arrest is relatively low and unchanged at about 15%. Our experience at Sahlgrenska Hospital in Göteborg indicates a higher rate. We found survival to be related to the type of arrhythmia initially encountered, the highest rate having been observed among patients in ventricular fibrillation. We also found survival among patients suffering cardiac arrest to be higher in monitored as opposed to non-monitored wards. Whether the improved survival rate observed at Sahlgrenska as compared with international observations among patients suffering cardiac arrest is due to improvements in the organization or to patient selection is not clear. In order to achieve a higher survival rate after in-hospital cardiac arrest an efficient organization in which health care providers are given regular training and feed back is most likely of the utmost importance.

A comparison between patients suffering in-hospital and out-of-hospital cardiac arrest in terms of treatment and outcome.

AIM: To compare treatment and outcome amongst patients suffering in-hospital and out-of-hospital cardiac arrest in the same community. PATIENTS: All patients suffering in-hospital cardiac arrest in Sahlgrenska University Hospital covering half the catchment area of the community of Göteborg (500 000 inhabitants) and all patients suffering out-of-hospital cardiac arrest in the community of Göteborg. Criteria for inclusion were that resuscitation efforts should have been attempted. TIME OF SURVEY: From 1 November 1994 to 1 November 1997. METHODS: Data were recorded both prospectively and retrospectively. RESULTS: In total, 422 patients suffered in-hospital cardiac arrest and 778 patients suffered out-of-hospital cardiac arrest. Patients with in-hospital cardiac arrest included more women and were more frequently found in ventricular fibrillation. The median interval between collapse and defibrillation was 2 min in in-hospital cardiac arrest compared with 7 min in out-of-hospital cardiac arrest (< 0.001). The proportion of patients being discharged from hospital was 37.5% after in-hospital cardiac arrest, compared with 8.7% after out-of-hospital cardiac arrest (P < 0.001). Corresponding figures for patients found in ventricular fibrillation were 56.9 vs. 19.7% (P < 0.001) and for patients found in asystole 25.2 vs. 1.8% (P < 0.001). CONCLUSION: In a survey evaluating patients with in-hospital and out-of-hospital cardiac arrest in whom resuscitation efforts were attempted, we found that the former group had a survival rate more than four times higher than the latter. Possible strong contributing factors to this observation are: (i) shorter time interval to start of treatment, and (ii) a prepared selection for resuscitation efforts.

Reorganization of nursing and medical care to reduce the incidence of postoperative delirium and improve rehabilitation outcome in elderly patients treated for femoral neck fractures.

The aim of this study was to evaluate the effectiveness of a nursing and medical intervention programme for the prevention and treatment of delirium in elderly patients treated for femoral neck fractures. Forty-nine patients consecutively admitted to an orthogeriatric rehabilitation unit in a county hospital in northern Sweden were compared with historical cohorts of corresponding patients in the same and other hospitals. There was a total reorganization of nursing and medical care of patients with femoral neck fractures. The intervention programme consisted of staff education, co-operation between orthopaedic surgeons and geriatricians, individual care and planning of rehabilitation, improved ward environment, active nutrition, improved continuity of care and prevention and treatment of complications associated with delirium. The main result of the study was that the incidence of delirium was significantly lower than in all previously published studies. The incidence of other postoperative complications was also lower, and a larger proportion of the patients regained independent walking ability and could return to their previous living conditions on discharge. It can be concluded that the intervention programme reduced the incidence and duration of delirium and improved functional outcome for elderly patients treated for femoral neck fractures.

Antibiotic susceptibility of 629 bacterial blood and CSF isolates from Swedish infants and the therapeutic implications.

Blood and CSF isolates (n = 629) from Swedish infants up to one year of age were tested in vitro against 13 antimicrobial agents in order to update the guidelines for empiric therapy of septicaemia and meningitis. Ampicillin plus gentamicin provided inadequate empiric therapy for meningitis, due to the poor CSF penetration of the aminoglycoside and the frequent occurrence of bacterial resistance to ampicillin. Ceftazidime and cefuroxime were moderately active, particularly against isolates from small infants. Cefotaxime today seemed to provide the best empiric therapy of septicaemia and meningitis in infants. Because of the occurrence of Listeria and enterococcal infections, ampicillin should initially be added and other combinations are also advisable for the occasional cases of Enterobacter, Citrobacter, Serratia, and Pseudomonas infections. For coagulase-negative staphylococci only vancomycin offered a broad activity (100% at achievable serum levels).

Characteristics and outcome among patients with a suspected in-hospital cardiac arrest.

AIM: To describe the characteristics and outcome among patients with a suspected in-hospital cardiac arrest. METHODS: All the patients who suffered from a suspected in-hospital cardiac arrest during a 14-months period, where the cardiopulmonary resuscitation (CPR) team was called, were recorded and described prospectively in terms of characteristics and outcome. RESULTS: There were 278 calls for the CPR team. Of these, 216 suffered a true cardiac arrest, 16 a respiratory arrest and 46 neither. The percentage of patients who were discharged alive from hospital was 42% for cardiac arrest patients, 62% for respiratory arrest and 87% for the remaining patients. Among patients with a cardiac arrest, those found in ventricular fibrillation/ventricular tachycardia had a survival rate of 64%, those found in asystole 24% and those found in pulseless electrical activity 10%. Among patients who were being monitored at the time of arrest, the survival rate was 52%, as compared with 27% for non-monitored patients (P= 0.001). Among survivors of cardiac arrest, a cerebral performance category (CPC) of 1 (no major deficit) was observed in 81% at discharge and in 82% on admission to hospital prior to the arrest. CONCLUSION: We conclude that, during a 14-month period at Sahlgrenska University Hospital in Göteborg, almost half the patients with a cardiac arrest in which the CPR team was called were discharged from hospital. Among survivors, 81% had a CPC score of 1 at hospital discharge. Survival seems to be closely related to the relative effectiveness of the resuscitation organisation in different parts of the hospital.

Clinical profile of delirium in patients treated for femoral neck fractures.

The incidence of delirium, its predisposing factors, clinical profile, associated symptoms and consequences were investigated in 54 consecutive patients, 19 men and 35 women, mean age 77.1 years, admitted to an 'ortho-geriatric unit' with femoral neck fractures. The incidence of postoperative delirium was 15/54 (27.8%) and a logistic regression model found that dementia and a prolonged waiting time for the operation increased the risk of postoperative delirium. Delirium during the night was most common but in 5 patients the delirium was worst in the morning. Patients with delirium suffered more anxiety, depressed mood, emotionalism, delusions and hallucinations. A larger proportion of patients with delirium could not return to their previous dwelling, and a larger proportion of delirious patients were either dead, wheelchair-bound or bedridden at the 6-month follow-up (p < 0.005). The conclusion is that delirium is common and has a serious impact on the outcome after hip fracture surgery.
