Abstract

Objectives.To evaluate the prevalence of long term oxygen therapy(LTOT) and the variables associated with it in Andalusia(population 6,796,964, surface 87,597 Km²).Methods.Prospective cross-sectional multicenter study in which factors influencing LTOT prevalence were analysed. Data on the use of LTOT were obtained from official figures from Local Health Authorities. Possible factors influencing the prescriptions were obtained form a survey sent to 29 public hospitals in the area (see abstract 250264). A study was performed to find out which factors influenced LTOT prevalence with a special emphasis in comparing those centres with a Specific Unit for the Control Of LTOT(SUCOL) and those without it.Results.Global prevalence of LTOT in the area was 184 per 100,000 (range 71 – 473). Significant differences in LTOT prevalence were found between centres with a SUCOL [17(58.6%) centres] and the rest of them (169vs237 per 100,000; p = 0.03). Altitude above sea level was also found to be a factor influencing LTOT prevalence(r = 0.73; p = 0.005). Other factors such as the age of the population, the Department responsible for the first prescription, and the attitude towards low compliant or active smoking patients did not influence LTOT prevalence.Conclusions.The presence of a SUCOL in Respiratory Departments is desirable, since the existence of a SUCOL implies a significant reduction on LTOT prevalence and a better control of the therapy.
