Hormone therapy prescription among physicians in France and Quebec

Differences in verbal memory performance in postmenopausal women receiving hormone therapy: 17β-estradiol versus conjugated equine estrogens

OBJECTIVE

Much controversy exists and many questions remain unanswered about the effects of hormone therapy (HT) on cognition in postmenopausal women. There is growing evidence suggesting that HT compounds containing conjugated equine estrogen (CEE) have negative effects on cognition whereas 17β-estradiol (17β-E) either has positive or neutral effects. The present study sought to further examine this issue in a sample of postmenopausal women with risk factors for Alzheimer's disease (AD).

DESIGN

Cross-sectional neuropsychological evaluation.

SETTING

Academic research clinic.

PARTICIPANTS

68 healthy postmenopausal women (aged 49-68) receiving either 17β-E or CEE for at least one year with increased risk for AD.

MEASUREMENTS

Neuropsychological test battery of the cognitive domains of attention/working memory/processing speed, verbal memory, visual memory, and executive functioning.

RESULTS

Multivariate analyses of variance (MANOVA) showed significantly better verbal memory performance in women receiving 17β-E compared to women receiving CEE regardless of age, IQ, years of education, risk factors for AD (including APOE-ε4 carriership), duration of endogenous and exogenous estrogen exposure, concurrent progesterone use, or natural versus surgical menopause status.

CONCLUSIONS

Verbal memory performance was better in postmenopausal women receiving 17β-E compared to CEE in a sample population of women with risk factors for AD. Genetic risk for AD as well as other confounds did not affect this finding. The results suggest a differential effect of HT type on verbal memory, with 17β-E being a preferential compound. Further evaluation of HT types, regimens and duration of use on cognitive performance in postmenopausal women in a controlled longitudinal design is warranted.

[Characteristics and determinants of initiation of premenopausal use of oral progestagens in the French E3N cohort]

OBJECTIVE

To describe the characteristics and determinants of initiation of use of progestagens alone - i.e. without concomitant use of estrogen - among French premenopausal women.

METHODS

Forty-one thousand six hundred and three women from the French E3N cohort were included in our analyses. Prevalence of use was calculated from 1992 to 2005. Determinants of progestagens alone initiation were investigated prospectively from 1992 to 2005, using multivariable Cox proportional hazards models.

RESULTS

Fifty-eight per cent of women who had reached menopause between 1992 and 2005 ever used progestagens alone during their premenopause. Between 1992 and the end of 1990s, the increase in the prevalence of progestagens alone use in our cohort was close to 50%. Initiation of progestagens alone was significantly associated with a high level of education (postgraduate compared to high-school graduate: Hazard ratio [HR]: 1.09 95% confidence interval [CI]: 1.01-1.18), with a normal body mass index (overweight and obese women compared to normal-weight women: HR=0.84, 95% CI: 0.79-0.90 and HR=0.79, 95% CI: 0.69-0.89 respectively), history of gynecological disorders (mastalgia, benign breast disease and benign uterine or ovarian disease [HR=1.38, 95% CI: 1.27-1.49, HR=1.18, 95% CI: 1.13-1.24 and HR=1.60, 95% CI: 1.52-1.68 respectively]) and with recent gynaecological screening (as measured by recently performed mammogram or Pap smear HR=1.11, 95% CI: 1.05-1.17 and HR=1.38, 95% CI: 1.27-1.49 respectively).

CONCLUSION

Since, at least in France, use of progestagens alone at premenopause is common, evaluation of its risks and benefits is of public health importance.

Hormone therapy discontinuation: physician practices after the Women's Health Initiative

OBJECTIVE

No guidelines or randomized trials address best practices for hormone therapy (HT) discontinuation.

METHODS

We conducted a survey study to explore HT discontinuation practices at Group Health and Harvard Vanguard, large integrated health systems in the Northwest and Northeast United States, focusing on differences between specialties and study site.

RESULTS

The response rate to the written questionnaire (mailed between December 2005 and May 2006) was 78.5% (736/928); this article reports the results for 483 eligible physicians. To discontinue oral HT, most physicians (91%) advised tapering, not immediate cessation (8%), and most (60%) suggested decreasing both dose and days per week. Almost 60% of physicians reported no experience with tapering patches. Harvard Vanguard physicians were more likely than Group Health physicians to encourage discontinuing HT and less likely to recommend resuming HT when a woman's symptoms returned after discontinuing HT. Physicians were most strongly influenced by their own experience (48%), advice from colleagues (25%), and the woman's preference (19%) when choosing a discontinuation strategy; only 2% relied on research evidence. Physicians endorsed various approaches to manage symptoms after HT discontinuation, most often behavioral changes (44%) and increased exercise (37%), and these approaches were more often endorsed by Harvard Vanguard physicians and obstetrician/gynecologists than Group Health physicians or family practitioners or internists.

CONCLUSIONS

Two health plans in the Northwestern and Northeastern United States have no standard protocol for HT discontinuation. Physicians customized approaches, influenced by their location, colleagues, and specialty. Research is needed to guide approaches to HT discontinuation.

The medical management of menopause: a four-country comparison care in urban areas

OBJECTIVE

To compare the medical management of menopause across urban areas in four countries which differ by level of income and degree of medicalization.

METHODS

Surveys of health providers who advise women on the menopausal transition were carried out in Beirut, Lebanon (n=100), Madrid, Spain (n=60), Worcester, MA, U.S. (n=59), and Rabat, Morocco (n=50) between 2002 and 2004. Physician characteristics, hormone therapy (HT) prescribing practices, and concerns about the management of menopause were compared across countries using chi(2) and logistic regression analyses.

RESULTS

Across sites, physicians were generally well informed about HT and thought that symptom alleviation and disease prevention were equally important. They had concerns about risks associated with HT, particularly breast cancer, and in 3 sites where the survey was conducted after the WHI (Beirut, Rabat, and Madrid) physicians changed their practices to prescribe HT less frequently, for shorter durations, or shifted to other medications. There were significant differences across sites in the recommended duration of HT, time spent talking with patients, perceived benefits of HT, tests recommended before prescribing HT, and concern about the risks associated with HT. Physicians in Madrid and Massachusetts were more likely to report that decisions about the management of menopause were difficult, but in all sites the main reason for difficulties was concerns about risks. The results also suggest discrepancies between physicians' perceptions and women's reports about the reasons why women consult at menopause.

CONCLUSIONS

Prescription patterns and perceived benefits of HT appear to reflect local medical culture rather than simply physician characteristics. The impact of the WHI study was seen in prescribing patterns and concerns about HT. Physicians in all four countries were generally well informed. Financial support: NIH 5 900 000196.

Physicians’ views and practices concerning menopausal hormone therapy

OBJECTIVE

To examine physicians' views and practices concerning estrogen+progestogen therapy (EPT).

DESIGN

Questionnaires were mailed to a random sample of physicians in the United States (US) in 2003. A total of 1614 (53.8%) surveys were returned (633 obstetricians and gynecologists (Ob/Gyns), 571 family practitioners, and 410 internists).

RESULTS

Only a minority of the physicians (16%) would offer EPT to menopausal women in the absence of menopausal symptoms (26% Ob/Gyn, 11% family practitioners, 6% internists, p<0.0001). However, many physicians (62%) believed that EPT could be offered "short term" to menopausal women with menopausal symptoms assuming no contraindications (82% Ob/Gyn, 54% family practitioners, 42% internists; p<0.0001). Irrespective of specialty, the strongest contraindications to EPT use reported by these physicians were personal history of breast cancer (93%), thrombosis (92%), cerebrovascular disease (84%), ischemic heart disease (74%), uterine cancer (73%), as well as women's subjective "concern" about breast cancer (57%). Procedures reported as always required by physicians for continuing women on EPT were breast examination (97%), mammogram (96%), blood pressure measurement (94%), and pelvic examination (91%).

CONCLUSIONS

Internists and family practitioners address more contraindications to EPT use than Ob-Gyns. Although many physicians appear to be accepting of short-term use of EPT for menopausal indications in the absence of contraindications, the majority would not prescribe it for prophylactic purposes.

The menopause in Spain: Results of the DAMES (Decisions At MEnopause) Study

OBJECTIVE

To assess the symptomatology of menopause and the use of hormone therapy among women in Spain.

METHODS

A survey conducted on a representative sample of 300 women aged 45-55 in Madrid. The instrument included closed- and open-ended questions about demographic and socio-economic information, health and reproductive history, symptoms in past month, use of health services, life style, and therapeutic decisions.

RESULTS

Eighty-three percent of respondents report five or more symptoms. Joint pains, weight gain, mood changes and nervousness are the most frequently reported; just under half of respondents report hot flashes; 4/5 report emotional/mental symptoms. The frequencies of some symptoms vary with socio-economic status. Two-thirds of respondents have consulted physicians, and 10% are currently taking hormone therapy; the use of hormone therapy is lower among women from the lower strata. One-fifth of respondents use of nonconventional and alternative medications. Just under half of respondents find that menopause is difficult.

CONCLUSION

Symptom reporting is relatively high, but general symptoms are more frequent than "core" menopausal symptoms. The use of hormone therapy is relatively low, but the use of alternative medicines is relatively high.

Variation in the psychosocial determinants of the intention to prescribe hormone therapy prior to the release of the Women's Health Initiative trial: a survey of general practitioners and gynaecologists in France and Quebec

BACKGROUND

Theory-based approaches are advocated to improve our understanding of prescription behaviour. This study is an application of the theory of planned behaviour (TPB) with additional variables. It was designed to assess which variables were associated with the intention to prescribe hormone therapy (HT). In addition, variations in the measures across medical specialities (GPs and gynaecologists) and across countries (France and Quebec) were investigated.

METHODS

A survey among 2,000 doctors from France and 1,044 doctors from Quebec was conducted. Data were collected by means of a self-administered questionnaire. A clinical vignette was used to elicit doctors' opinions. The following TPB variables were assessed: attitude, subjective norm, perceived behavioural control, attitudinal beliefs, normative beliefs and power of control beliefs. Additional variables (role belief, moral norm and practice pattern-related factors) were also assessed. A stepwise logistic regression was used to assess which variables were associated with the intention to prescribe HT. GPs and gynaecologists were compared to each other within countries and the two countries were compared within the specialties.

RESULTS

Overall, 1,085 doctors from France returned their questionnaire and 516 doctors from Quebec (response rate = 54% and 49%, respectively). In the overall regression model, power of control beliefs, moral norm and role belief were significantly associated with intention (all at p < 0.0001). The models by specialty and country were: for GPs in Quebec, power of control beliefs (p < 0.0001), moral norm (p < 0.01) and cytology and hormonal dosage (both at p < 0.05); for GPs in France, power of control beliefs and role belief (both at p < 0.0001) and perception of behavioural control (p < 0.05) and cessation of menses (p < 0.01); for gynaecologists in Quebec, moral norm and power of control beliefs (both at p = 0.01); and for gynaecologists in France, power of control beliefs (p < 0.0001), and moral norm, role belief and lipid profile (all at p < 0.05).

CONCLUSION

In both countries, compared with GPs, intention to prescribe HT was higher for gynaecologists. Psychosocial determinants of doctors' intention to prescribe HT varied according to the specialty and the country thus, suggesting an influence of contextual factors on these determinants.

French hormones: progestins and therapeutic variation in France

Western medicine is seen as universally valid, but in reality it displays a wide range of national and local variability. Our paper focuses on one such case of local variation: the widespread use of progestins in France to treat various pre-menopausal conditions as well as for contraception. The case of progestins allows us to explore how specific styles of research may come to dominate a particular local medical culture, and how they are influenced by changing criteria of scientific validity and wider social relations. We argue that in the 1980s and 1990s a single prestigious research-oriented Parisian hospital service played a dominant role in the transformation of progestins into scientifically validated medical practice. This status was not called seriously into question until recently when foreign research on a different form of hormone therapy suggested that risk was associated with their use. We also propose that both the research around and medical use of progestins in France was shaped by the positive attitude of many French women, including feminists, to hormonal therapies and to the non-surgical specialty most closely associated with hormones, medical gynaecology.
