In-hospital cardiac arrest: Incidence, prognostic factors and results

BACKGROUND AND AIMS

In-hospital cardiac arrest (CA) is a clinical entity with high morbidity and mortality that occurs in up to 2% of hospitalized patients. It is a public health problem with important economic, social, and medical repercussions, and as such its incidence needs to be reviewed and improved. The aim of this study was to determine the incidence of in-hospital CA, return of spontaneous circulation (ROSC), and survival rates at Hospital de la Princesa, and to define the clinical and demographic characteristics of patients with in-hospital CA.

PATIENTS AND METHODS

Retrospective observational chart review of patients presenting in-hospital CA and treated by anaesthesiologists from the hospital's rapid intervention team. Data were collected over 1 year.

RESULTS

Forty four patients were included in the study, of which 22 (50%) were women. Mean age was 75.7 years (±15.78 years), and incidence of in-hospital CA was 2.88 per 100,000 hospital admissions. Twenty two patients (50%) achieved ROSC and 11 patients (25%) survived until discharge home. The most prevalent comorbidity was arterial hypertension (63.64%); 66.7% of cases were not witnessed, and only 15.9% presented a shockable rhythm.

CONCLUSIONS

These results are similar to those reported in other larger studies. We recommend introducing immediate intervention teams and devoting time to training hospital staff in in-hospital CA.

Patient-staff safety applications: the evaluation of blue code reports

OBJECTIVE

Blue code systems (BCS) are communication systems that ensure the most rapid and effective resuscitation when a patient is in respiratory or cardiac arrest. A hospital employee faced with the situation of a cardiopulmonary arrest (CPA) starts the system by dialing 6666 from any phone in the hospital. We created a five-person team that includes a doctor, nurse, anesthesia technician, stretcher officer and security guard. The purpose of this study is to share our experiences in initiating the use of the BCS in our hospital.

MATERIALS AND METHODS

In our hospital, the records of calls that were made by Callvision BCS were analyzed retrospectively from May 2010 to the end of January 2011.

RESULTS

A total of 474 calls were made using the blue code system. Of those calls, 402 (84.5%) were determined to be inappropriate calls. The remaining 72 calls were responded to. Of the 72 patients who were treated, 21 were discharged after they were hospitalized in the service or intensive care unit, 45 cases resulted in exitus, and 5 cases were referred to the Ataturk University faculty of medicine.

CONCLUSION

The BCS has achieved its goal. The discharge rate of 29.5% that we achieved is a successful result.

The sounds of cardiac arrest: innovating to obtain an accurate record during in-hospital cardiac arrest

BACKGROUND

To obtain an accurate audit during in-hospital cardiac arrest, following recommendations of the Utstein style and measuring time intervals between the different interventions, is difficult.

OBJECTIVE

To assess whether the use of an audio recording system during in-hospital cardiac arrest resuscitation allows the register of more items during cardiopulmonary resuscitation.

MATERIAL AND METHODS

Prospective observational study between January 2008 and December 2009. The population that were included, were hospitalized patients and non-hospitalized patients assisted by a cardiac arrest team, except for critical areas. An audio recording system with a timer was turned on when cardiac arrest team was alerted. Recordings were reviewed to fill in the items recommended by the Utstein style. Time intervals were calculated. Mean number of completed items per patient were compared between recorded and non-recorded cardiac arrest.

RESULTS

119 CA team alerts took place. 64 (53.7%) cases were real CA and 37 (57.8%) of them were properly recorded. A mean number of items per patient in recorded cardiac arrest cases were 18.18 (±3.2) vs. 15.96 (±4.1) in non-recorded cardiac arrest cases (p<0.05). In the recorded cases, mean times were: alert - arrival: 1.23 (±0.95)min; arrival - cardiopulmonary resuscitation initiation: 0.63 (±0.38)min; arrival - first defibrillation: 2.06 (±1.33)min; arrival - intubation: 8.42 (±4.64)min; arrival - first adrenaline: 3.30 (±1.98)min.

CONCLUSIONS

The audio recording system permits the register of a larger number of items per patient during in-hospital cardiac arrest and allows measurement of time intervals between the different interventions during cardiopulmonary resuscitation.

[Ethics of the cardiopulmonary resuscitation decisions]

Cardiopulmonary Resuscitation (CPR) must be attempted if indicated, not done if it is not indicated or if the patient does not accept or has previously rejected it and withdrawn it if it is ineffective. If CPR is considered futile, a Do-Not-Resuscitate Order (DNR) will be recorded. This should be made known to all physicians and nurses involved in patient care. It may be appropriate to limit life-sustaining-treatments for patients with severe anoxic encephalopathy, if the possibility of clinical evolution to brain death is ruled out. After CPR it is necessary to inform and support families and then review the process in order to make future improvements. After limitation of vital support, certain type of non-heart-beating-organ donation can be proposed. In order to acquire CPR skills, it is necessary to practice with simulators and, sometimes, with recently deceased, always with the consent of the family. Research on CPR is essential and must be conducted according to ethical rules and legal frameworks.
