Does smog increase the general practitioner's workload?

Dublin city experienced a week-long episode of intense smog in November 1988. A retrospective analysis was carried out in ten general practices of the numbers of patients seen during November. Each practice was situated in an area affected by high smog levels. The numbers of patients seen in surgery and on house-calls showed no differences during the weeks preceding the smog outbreak, during the period of high smog levels or during the week after this period. No qualitative data on the reasons for patients' visits were collected and no comments can be made on the nature of patients' illnesses during this period. There was no evidence for an increased workload in general practice caused by this episode of intense smog but a prospective study is necessary to confirm this finding and to examine the nature of patients' problems during such an episode.
