title: [The primary care frequent attender profile].
abstract: BACKGROUND
  Frequent attenders are believed to represent a problem in Primary Care, with human, economic and social impact. The present study aimed to describe these patients' sociodemographic and pathological characteristics.
  
  
  METHODS
  A cross-sectional study with analytical component was conducted in the population of frequent attenders in a Portuguese Primary Health Care Practice, between January 2007 and December 2009, allocated to six General Practitioners. Sociodemographic characteristics as well as data related to physical and mental illness were collected from clinical records. Associations between variables were tested with χ-square and t-test. The top quartile of frequent attenders was compared with the remaining population. The adopted significance level was 0.05.
  
  
  RESULTS
  Of the 582 individuals evaluated, with a mean age of 55.4 years (men 58.6 and women 54.3; p = 0.006), 85% had chronic physical illness and 42% had chronic psychiatric illness. In the upper quartile of frequent attenders was observed a higher prevalence of chronic psychiatric illness (p < 0.001), as well as multiple pathology (p = 0.01), when compared to the remaining population. Individuals with physical illness were older (mean age: 58.0 years vs 40.1 years; p < 0.001) while those with chronic psychiatric illness were younger (mean age 53.7 years vs 56.6; p = 0.035).
  
  
  CONCLUSIONS
  It was drawn a profile of the frequent attender consistent with international literature, at a time when there are no studies in Portuguese Primary Care settings. Information and selection bias were detected and minimized. In order to discriminate between frequent attenders, the upper quartile was compared with the remaining population. Some features seemed to be more associated with frequent attendance, such as advanced age, low educational level and the presence of chronic psychiatric illness.
  
  
  CONCLUSIONS
  The frequent attender of this Portuguese Primary Care Practice is a female, in the sixth decade of life, with low educational level, married or living as a couple, coming from a nuclear family, and often with chronic illness. Knowledge of these patients may allow the development of strategies that lead to more cost-effective health care services. This study shows some guidelines for studies on this important population.
