Hormone replacement therapy: changes in frequency and type of prescription by Dutch GPs during the last decade of the millennium.
OBJECTIVE
The present study was conducted in order to determine the change of frequency and type of hormone replacement therapy (HRT) regimen newly prescribed by Dutch GPs.


METHODS
A comparison was made of two data sets (multi-stage random samples) collected in 1987/88 and from 1995 to 1998 concerning women 40 years and older who were newly prescribed HRT.


RESULTS
Compared with 1987/88, 50% more patients were newly prescribed HRT in 1998 (2.0 in 1987/88 and 3.0 in 1998 per 1000 registered women, P < 0.01). The age distribution remained about the same, with a peak between 50 and 54 years in each year of registration. Unopposed oestrogens (including plasters) were prescribed less frequently (1.3 per thousand in 1987/88 versus 0.7 per thousand in 1998, P < 0.001), and combinations of oestrogen and progestogen more frequently in 1998 (0. 2 per thousand in 1987/88 versus 1.8 per thousand in 1998, P < 0. 01). Sequential therapy was prescribed slightly more frequently than continuous therapy (65% sequential therapy in 1995; 55% in 1998). The most frequent reason for starting HRT in 1995-1998 was climacteric symptoms (89-98%), followed by osteoporosis prevention (16-28%) and early menopause (13-25%). Rarely were preventive goals the only reason (6%) for prescribing HRT.


CONCLUSIONS
The number of HRT prescriptions increased by 50% over the last decade of the millennium. The age distribution remained the same. There was a tendency to shift from prescribing unopposed oestrogens to combinations of oestrogens and progestogens. Alleviation of climacteric symptoms was the main reason for prescribing HRT throughout the registration period. Prescription of HRT for prevention of osteoporosis and/or cardiovascular disease has so far not been adopted on a large scale by Dutch GPs.
