UK neonatal intensive care services in 1996. On behalf of the UK Neonatal Staffing Study Collaborative Group.

A census of activity and staff levels in 1996 was conducted in UK neonatal units and achieved a 100% response from 246 units. Among the 186 neonatal intensive care units, the median (interquartile range) number of total cots was 18(14-22); level 1 intensive care cots 4(2-6); total admissions 318(262-405); very low birthweight admissions 40(28-68); and the number ventilated or given CPAP by endotracheal tube 52(32-83). Forty six (25%) intensive care units lacked the recommended minimum of one consultant with prime responsibility for neonatal medicine. As a conservative estimate 79% of intensive care units had a lower nursing provision than that recommended in previously published guidelines. There was substantial variation in activity and staffing levels among units.

A numerical model of an intensive care ventilator-humidifier system.

Current intensive care ventilator-humidifier systems neither monitor nor adequately control inspired gas humidity. Problems of low delivered humidity and condensation within ventilator circuitry are commonly encountered. To help to address these problems, a numerical model of a complete ventilator-humidifier-patient intensive care system has been developed. The model, based on a finite difference technique, can predict pressures, flow-rates, temperatures and relative humidities at discrete points throughout the system. A comparison of numerical predictions and measurements in a real system is reported. A strong qualitative agreement is demonstrated in all cases studied, and a good quantitative agreement is obtained in most cases. It is concluded that such models could be used to assess methods of controlling ventilator-humidifier systems to prevent the occurrence of condensation. Similar models could be developed for other medical gas delivery systems.

Economics of infection at the extremes of age.

People are more vulnerable to infection at the extremes of age for a variety of reasons, the most important being that they are more likely to be in hospital in a crowded ward environment and to be at risk from hospital acquired infection. Recognition of this increased vulnerability to infection should be accompanied by equal emphasis on their increased susceptibility to nosocomial disease arising from the diagnosis or treatment of infection. An economic evaluation of infection at the extremes of age should include an assessment of need made in terms of the capacity of patients to benefit from investigation or treatment. Benefits should not be confused with treatment effects such as reduction in pyrexia or correction of other physiological abnormalities. Ideally benefits should be quantified in a manner which allows comparison with the cost-effectiveness of other uses of health care resources. In order to achieve this aim clinicians must understand the economic terms opportunity cost and marginal cost-effectiveness. These terms are defined in general terms and then applied to examples of investigation, prevention and treatment of infection at the extremes of age.
