Outcome of home mechanical ventilation

To determine the outcome of patients discharged home on portable ventilator. The Aga Khan University Hospital, Karachi from January 2000 to December 2004. All ventilator-dependent patients discharged home were contacted. Survivors were administered the EQ-5D Quality-of-Life instrument. SPSS version 13 was used to analyze data. Eleven patients were discharged home on invasive ventilation. Mean age was 49 years [range10-98 years]. Cause of ventilatory failure were cervical spine trauma in 36%, primary neurological disease in 27%, critical illness neuropathy and respiratory failure in 18% each. Survival rate was 73%, with three deaths. Mean duration of ventilation was 9.45 months [95% CI 3.24, 15.67]. Rate of successful weaning after discharge was 36%, with 4 patients off all forms of ventilatory support and 2 on only nocturnal support. A 2.8 [95% CI 0.5, 16.6] relative risk towards successful weaning was associated with the presence of a family member as the primary care giver. Mean scores on the EQ-5D descriptive tool were; mobility 2 [ +/- 0.82], self-care 2 [ +/- 0.82], usual activities 1.86 [ +/- 0.69], pain/discomfort 1.43[ +/- 0.79], anxiety/depression 1.29 [ +/- 0.76]. Mean score on the EQ-VAS was 48.2[ +/- 27.3]. In carefully selected patients, home ventilation is a viable option with the expectation of successful weaning and survival. Patients discharged home on ventilation reported a reasonably good quality of life with proportionately more problems related to independence compared to overall well-being

Apache II score as a predictor of length of stay and outcome in our ICUS

The APACHE II [acute physiology and chronic health evaluation] is used widely for predicting probability of hospital mortality and length of stay in the ICU. APACHE II forms were available to all ICU residents within 24 hours of admission, and a score was assigned to them. Based on our results the APACHE II score has reliably predicted an outcome of the least amount of length of stay [LOS] in the ICU as well as a 100% probability of being shifted out of the ICU for a score of <10 [according to international benchmarks]. This reliable scoring system can be used for predicting mortality and length of stay and therefore, resource allocation, antibiotic use and ethical decisions regarding counseling families about end of life decisions - all within 24 hours of admissions
