Abstract
Objective. To examine changes in the numbers of inpatient episodes and inpatient days and length of stay in acute exacerbations of COPD (chronic obstructive pulmonary disease) by specialization and by age group and sex distribution relative to the total population in the years 1995–2001.
Design. A register-based study.
Subjects. Data on inpatient episodes for patients aged 45 years or over with a principal diagnosis of COPD beginning in 1995–2001 and lasting less than 90 days were extracted from the hospital discharge register of the Finnish National Research and Development Centre for Welfare and Health.
Main outcome measures. Numbers of inpatient episodes and days by age and sex in the specialities of general practice, pulmonary medicine, and internal medicine.
Results. The annual number of inpatient episodes increased by 10.9% from 1995 to 2001. The number of emergency treatment episodes supervised by a general practitioner increased by 36.8% during the same period and the number of such episodes supervised by a pulmonary specialist by 17.8%. The increase in age-adjusted emergency treatment episodes for men was 0.8% and that for women 18.5%. The average hospital stay shortened from 8.0 (SD 8.0) to 6.5 (SD 6.2) for men and from 8.7 (SD 8.5) to 7.3 (SD 6.8) for women.
Conclusions. The greater increase in inpatient episodes for exacerbations of COPD in relation to the total population among women than among men may be attributed to differences in smoking habits and ageing between the sexes. Responsibility for COPD cases is clearly shifting to general practitioners. This is due partly to the national programme for the treatment of obstructive pulmonary diseases and the associated in-service training provided for general practitioners and partly to financial reasons. More detailed investigations should be made into the quality of the treatment.
