ICUs worldwide: an overview of critical care medicine in South Africa

South Africa has undergone rapid changes in the political and social arenas since 1994. With new policy-makers in the Department of Health, the distribution of health care resources are being rationalised and redirected to benefit the majority of the previously disadvantaged population of the country. The role and rationalisation of intensive care medicine has to be re-evaluated to ascertain that it is at a level appropriate for a developing country. Despite progress made, the subspecialty of intensive care medicine faces challenges from changing disease patterns and from lack of human and financial resources as these are redirected to primary health care and other priorities facing the country.     

The experience of the nurse caring for families of patients at the end of life in the intensive care unit

The patient who enters at the intensive care unit (ICU) usually does because of health conditions that are sometimes irreversible and lead to death, and the care at the end of life becomes the main factor of this situation; therefore, the aim of this article was to understand the meaning of the experience of giving care to families at the end of life in an ICU. For this reason, a qualitative, hermeneutic phenomenological research was carried out. For the data collection, a semi‐structured interview was conducted to 18 participants, and the results were returned to each of the participants in order to validate each of the categories and interpretations. Among these results, two main categories were identified: emotional response of the nurse to the family and nursing care to the family of patients at the end of life. It was concluded that the nurses working at the ICU are facing aspects related to the end of life that generates emotional and psychological burden; additionally, they do not have specific training in this subject, especially in relation to the care of the families in this situation, for which they provide this care based on empiricism.     

Oral care practices of intensive care nurses: A descriptive study

The aim of this study was to investigate intensive care unit (ICU) nurses’ views and practices on oral care and to define the factors related to oral care measures. A study was carried out in eight ICUs of a teaching hospital in 2008. One hundred one nurses constituted the study sample. The data were collected using ‘Oral Care Practices Survey’ which included demographic characteristics (5 items) and current oral care practices (13 items). Oral care was given the highest priority by nearly 60% of the nurses. The most commonly used solution was sodium bicarbonate (79.2%), and the most frequently used equipment was foam swab (82.2%). Oral care was carried out less than every 4 h per day by 44.5% of the nurses. The oral care products and solutions were reported to be different in almost every unit. The relationship between the use of toothpaste and the place of employment was statistically significant (x² = 24.566, d.f. = 6, P = 0.000). There was a statistical significance between the clinics and frequency of oral care (x² = 81.486, d.f. = 42, P = 0.000). This study suggests that there is a wide variety of type and frequency of oral care measures among ICU nurses. Optimal oral care supported by evidence is an effective prevention method for eliminating oral complications.     

The impact of a physician-staffed mobile intensive care unit

In the United States, mobile intensive care units (MICU) staffed by paramedical personnel are the means by which virtually all patients are transported to hospitals. However, in many other countries, MICUs are physician-staffed. The role of physicians in the MICU in delivering emergency pre-hospital care in Israel was examined. In one year's experience on a physician-attended MICU, 1,200 of 3,919 patients (31%) were definitively treated in the pre-hospital phase and not transported to a hospital facility. A careful follow-up of these patients is reported. In 235 cases death was pronounced by the MICU physician, and the patient was not transported. In 965 cases, the problem was diagnosed and the patient treated without a referral for further immediate treatment. Follow-up was obtained for 869 (90%) of these patients, of whom 843 (97%) required no additional emergency attention during the 48-hour follow-up period. The use of a physician-attended MICU reduces the service load on emergency departments.     

Influence of a dedicated paediatric cardiac intensive care unit on patient outcomes

Background: The impact of a designated intensive care unit (ICU) for postoperative cardiac care in children is not clear. In our hospital (in the USA), we started a new Paediatric Cardiac Surgery programme 5 years ago, in September 2004. During the first 2 years of the programme, postoperative care was accomplished within the general paediatric ICU (PICU or c‐ICU). Subsequently, in September 2006, a dedicated cardiac ICU (d‐ICU) was established. We looked at our experience during these two periods to determine whether the designation of a separate ICU affected outcomes for these children. Design and Methods: We obtained Institutional Review Board (IRB) approval to review the medical records for all postoperative cardiac admissions to the ICU during the first 4 years of the programme (September 2004–September 2008). Variables collected included age, gender, diagnosis, type of cardiac surgery, Risk Adjustment for Congenital Cardiac Surgery, version 1 (RACHS‐1) classification, ventilator use, hospital stay, invasive line infections, ventilator‐related infections, wound infections, need for cardiopulmonary support, return to the operating room, re‐exploration of the chest, delayed sternal closure, accidental extubations, re‐intubation and mortality rates. These variables were summed and compared for the combined PICU and the dedicated paediatric cardiac ICU. Results: There were 199 cases performed in the first 2 years compared with 244 in the following 2 years. We saw a statistically insignificant increase in the number and complexity of cases during the second period (p = 0·08). However, morbidity declined as evidenced by the decrease in wound infection (p < 0·001) and need for chest re‐exploration (p < 0·001). In addition, mortality declined from 7 of 199 (3·5%) to 2 of 244 (0·8%). p < 0·04 and less children required resuscitation (p < 0·01). Conclusions: We believe the designation of a specific area for postoperative cardiac care was instrumental in the growth and development of our cardiac programme. This rapid change accomplished several crucial elements that lead to accelerated improvement in patient care and a decline in morbidity and mortality.
