The accessibility by telephone of primary health care was studied in Reykjavik and its surrounding municipalities. Comparison was also made between community run health centres and private practices. About 60% of the total population of Iceland live within the study area. The study used medical secretaries as patient substitutes. During the prescribed telephone time, all "patients" were able to make telephone contact with their practice facilities, and 80% reached their doctor within 10 min. The waiting time for non-acute appointments was never more than three days. The study did not detect any difference in accessibility between community run health centres and privately owned GP practices.
