EVALUATION OF MACROCYTOSIS BY GENERAL-PRACTITIONERS

Objective: Macrocytosis is considered to be an important sign of disea se, although it often seems to be ignored. The aim of the present stud y was to assess the quality of the work done by general practitioners using macrocytosis as an indicator. Method: All consecutive outpatient s at Tampere City Health Center who had blood counts taken during 8 mo nths in 1990 and were found to have macrocytosis (MCV greater than or equal to 100 femtoliters) that had not earlier been examined, were inc luded in this study. The further examinations undertaken were analyzed . Results: Of the 9,527 blood counts, previously unexamined macrocytos is was found in 3% (n = 287, 154 men and 133 women). Further examinati on because of macrocytosis was undertaken in 65 (42%) men and in 48 (3 6%) women. Alcohol abuse was the most common disease present in 52 (80 %) men and in 22 (46%) women. No cause for macrocytosis was found in s even men and in 17 women. No difference between the examined and unexa mined groups was found concerning medical history, medications, sympto ms, or blood count values, including hemoglobin and MCV. Conclusions: Evaluation of macrocytosis, when undertaken, was well done by general practitioners. However, it was performed too seldom and, thus, several diseases, especially alcohol abuse, may have been overlooked.
