Clinical decision support system (CDSS) – effects on care quality

Purpose – Despite their efficacy, some recommended therapies are underused. The purpose of this paper is to describe clinical decision support system (CDSS) development and its impact on clinical guideline adherence. Design/methodology/approach - A new CDSS was developed and introduced in a cardiac intensive care unit (CICU) in 2003, which provided physicians with patient-tailored reminders and permitted data export from electronic patient records into a national quality registry. To evaluate CDSS effects in the CICU, process indicators were compared to a control group using registry data. All CICUs were in the same region and only patients with acute coronary syndrome were included. Findings – CDSS introduction was associated with increases in guideline adherence, which ranged from 16 to 35 per cent, depending on the therapy. Statistically significant associations between guideline adherence and CDSS use remained over the five-year period after its introduction. During the same period, no relapses occurred in the intervention CICU. Practical implications – Guideline adherence and healthcare quality can be enhanced using CDSS. This study suggests that practitioners should turn to CDSS to improve healthcare quality. Originality/value – This paper describes and evaluates an intervention that successfully increased guideline adherence, which improved healthcare quality when the intervention CICU was compared to the control group

Out of hospital cardiac arrest outside home in Sweden, change in characteristics, outcome and availability for public access defibrillation

<p>Abstract</p> <p>Background</p> <p>A large proportion of patients who suffer from out of hospital cardiac arrest (OHCA) outside home are theoretically candidates for public access defibrillation (PAD). We describe the change in characteristics and outcome among these candidates in a 14 years perspective in Sweden.</p> <p>Methods</p> <p>All patients who suffered an OHCA in whom cardiopulmonary resuscitation (CPR) was attempted between 1992 and 2005 and who were included in the Swedish Cardiac Arrest Register (SCAR). We included patients in the survey if OHCA took place outside home excluding crew witnessed cases and those taken place in a nursing home.</p> <p>Results</p> <p>26% of all OHCAs (10133 patients out of 38710 patients) fulfilled the inclusion criteria. Within this group, the number of patients each year varied between 530 and 896 and the median age decreased from 68 years in 1992 to 64 years in 2005 (p for trend = 0.003). The proportion of patients who received bystander CPR increased from 47% in 1992 to 58% in 2005 (p for trend < 0.0001). The proportion of patients found in ventricular fibrillation (VF) declined from 56% to 50% among witnessed cases (p for trend < 0.0001) and a significant (p < 0.0001) decline was also seen among non witnessed cases.</p> <p>The median time from cardiac arrest to defibrillation among witnessed cases was 12 min in 1992 and 10 min in 2005 (p for trend = 0.029). Survival to one month among all patients increased from 8.1% to 14.0% (p for trend = 0.01). Among patients found in a shockable rhythm survival increased from 15.3% in 1992 to 27.0% in 2005 (p for trend < 0.0001).</p> <p>Conclusion</p> <p>In Sweden, there was a change in characteristics and outcome among patients who suffer OHCA outside home. Among these patients, bystander CPR increased, but the occurrence of VF decreased. One-month survival increased moderately overall and highly significantly among patients found in VF, even though the time to defibrillation changed only moderately.</p

The impact of CPR and AED training on healthcare professionals' self-perceived attitudes to performing resuscitation

Background: Healthcare professionals have shown concern about performing mouth-to-mouth ventilation due to the risks to themselves with the procedure. However, little is known about healthcare professionals' fears and attitudes to start CPR and the impact of training. Objective: To examine whether there were any changes in the attitudes among healthcare professionals to performing CPR from before to after training. Methods: Healthcare professionals from two Swedish hospitals were asked to answer a questionnaire before and after training. The questions were relating to physical and mental discomfort and attitudes to CPR. Statistical analysis used was generalized McNemar's test. Results: Overall, there was significant improvement in 10 of 11 items, reflecting various aspects of attitudes to CPR. All groups of health care professionals (physicians, nurses, assistant nurses, and "others" = physiotherapists, occupational therapists, social welfare officers, psychologists, biomedical analysts) felt more secure in CPR knowledge after education. In other aspects, such as anxiety prior to a possible cardiac arrest, only nurses and assistant nurses improved. The concern about being infected, when performing mouth to mouth ventilation, was reduced with the most marked reduction in physicians (75%; P &lt; 0.001). Conclusion: In this hospital-based setting, we found a positive outcome of education and training in CPR concerning healthcare professionals' attitudes to perform CPR. They felt more secure in their knowledge of cardiopulmonary resuscitation. In some aspects of attitudes to resuscitation nurses and assistant nurses appeared to be the groups that were most markedly influenced. The concern of being infected by a disease was low

Hospital employees' theoretical knowledge on what to do in an in-hospital cardiac arrest

<p>Abstract</p> <p>Background</p> <p>Guidelines recommend that all health care professionals should be able to perform cardiopulmonary resuscitation (CPR), including the use of an automated external defibrillator. Theoretical knowledge of CPR is then necessary.</p> <p>The aim of this study was to investigate how much theoretical knowledge in CPR would increase among all categories of health care professionals lacking training in CPR, in an intervention hospital, after a systematic standardised training. Their results were compared with the staff at a control hospital with an ongoing annual CPR training programme.</p> <p>Methods</p> <p>Health care professionals at two hospitals, with a total of 3144 employees, answered a multiple-choice questionnaire before and after training in CPR. Bootstrapped chi-square tests and Fisher's exact test were used for the statistical analyses.</p> <p>Results</p> <p>In the intervention hospital, physicians had the highest knowledge pre-test, but other health care professionals including nurses and assistant nurses reached a relatively high level post-test. Improvement was inversely related to the level of previous knowledge and was thus most marked among other health care professionals and least marked among physicians.</p> <p>The staff at the control hospital had a significantly higher level of knowledge pre-test than the intervention hospital, whereas the opposite was found post-test.</p> <p>Conclusions</p> <p>Overall theoretical knowledge increased after systematic standardised training in CPR. The increase was more pronounced for those without previous training and for those staff categories with the least medical education.</p

Early identification and delay to treatment in myocardial infarction and stroke: differences and similarities

<p>Abstract</p> <p>Background</p> <p>The two major complications of atherosclerosis are acute myocardial infarction (AMI) and acute ischemic stroke. Both are life-threatening conditions characterised by the abrupt cessation of blood flow to respective organs, resulting in an infarction. Depending on the extent of the infarction, loss of organ function varies considerably.</p> <p>In both conditions, it is possible to limit the extent of infarction with early intervention. In both conditions, minutes count.</p> <p>This article aims to describe differences and similarities with regard to the way patients, bystanders and health care providers act in the acute phase of the two diseases with the emphasis on the pre-hospital phase.</p> <p>Method</p> <p>A literature search was performed on the PubMed, Embase (Ovid SP) and Cochrane Library databases.</p> <p>Results</p> <p>In both conditions, symptoms vary considerably. Patients appear to suspect AMI more frequently than stroke and, in the former, there is a gender gap (men suspect AMI more frequently than women).</p> <p>With regard to detection of AMI and stroke at dispatch centre and in Emergency Medical Service (EMS) there is room for improvement in both conditions. The use of EMS appears to be higher in stroke but the overall delay to hospital admission is shorter in AMI. In both conditions, the fast track concept has been shown to influence the delay to treatment considerably.</p> <p>In terms of diagnostic evaluation by the EMS, more supported instruments are available in AMI than in stroke. Knowledge of the importance of early treatment has been reported to influence delays in both AMI and stroke.</p> <p>Conclusion</p> <p>Both in AMI and stroke minutes count and therefore the fast track concept has been introduced. Time to treatment still appears to be longer in stroke than in AMI. In the future improvement in the early detection as well as further shortening to start of treatment will be in focus in both conditions. A collaboration between cardiologists and neurologists and also between pre-hospital and in-hospital care might be fruitful.</p

Occupational affiliation does not influence practical skills in cardiopulmonary resuscitation for in-hospital healthcare professionals

<p>Abstract</p> <p>Background</p> <p>D-CPR (Defibrillator Cardiopulmonary Resuscitation) is a technique for optimal basic life support during cardiopulmonary resuscitation (CPR). Guidelines recommend that healthcare professionals can perform CPR with competence. How CPR training and provision is organized varies between hospitals, and it is our impression that in Sweden this has generally improved during the last 15-20 years. However, some hospitals still do not have any AED (Automated External Defibrillators). The aim was to investigate potential differences in practical skills between different healthcare professions before and after training in D-CPR.</p> <p>Methods</p> <p>Seventy-four healthcare professionals were video recorded and evaluated for adherence to a modified Cardiff Score. A Laerdal Resusci Anne manikin in connection to PC Skill reporting System was used to evaluate CPR quality. A simulated CPR situation was accomplished during a 5-10 min scenario of ventricular fibrillation. Paired and unpaired statistical methods were used to examine differences within and between occupations with respect to the intervention.</p> <p>Results</p> <p>There were no differences in skills among the different healthcare professions, except for compressions per minute. In total, the number of compression per minute and depth improved for all groups (<it>P </it>< 0.001). In total, 41% of the participants used AED before and 96% of the participants used AED after the intervention (<it>P </it>< 0.001). Before intervention, it took a median time of 120 seconds until the AED was used; after the intervention, it took 82 seconds.</p> <p>Conclusion</p> <p>Nearly all healthcare professionals learned to use the AED. There were no differences in CPR skill performances among the different healthcare professionals.</p

Epidemiology of cardiac arrest outside and inside hospital Experiences from registries in Sweden

Cardiac arrest is a dramatic condition leading to sudden death if someone cannot perform two interventions, basic life support and early defibrillation, that have been proved to improve long-term survival. The ‘Utstein style’, recently introduced, represents a standard of practice both inside and outside hospital with recommended guidelines for the uniform reporting of clinical data from the patient suffering cardiac arrest. In Sweden the vast majority of patients suffering from cardiac arrest regardless whether inside or outside hospital are included in webbased national registers (one for out-of-hospital cardiac arrest (OHCA) and one for in-hospital-cardiac arrest (IHCA)). In this article we will present our experiences from OHCA and IHCA separately
