British Columbia's health reform: "new directions" and accountability.

The health policy New Directions committed the British Columbia government to a population health perspective and extensive community involvement in the health services reform process. The policy envisaged elected citizen boards with authority to raise revenues and exercise a significant degree of local autonomy. Academic and public attention has been paid to the decision in November 1996 to collapse New Directions' two-tier governance structure into a single level. Less attention has been paid to the profound changes that occurred prior to the government's reversal on the question of governance. This paper focuses on those changes. During the critical three years between the 1993 launch of the reform and its formal revision in 1996, the government's positions on elections, taxation power, local autonomy and scope of action for regional boards all changed. Those changes marked a retreat from political accountability to the community and an advance towards managerial accountability to the government.

Beliefs about contraceptive sterilization among low-income urban women.

Among a group of low-income clinic patients planning to be sterilized, the vast majority--95 percent--reported believing that sterilization is the surest way to avoid getting pregnant and that it is safer than other contraceptive methods. Among a comparison group who also wanted no more children but did not plan to be sterilized, the majority also held these beliefs, but the proportion was lower (76-80 percent). In both groups, however, only between 64 and 70 percent knew that sterilization makes it impossible to have children in the future. Between 63 and 68 percent of the women in the sterilization group believed that having the operation would improve their family relationships, emotional state and other aspects of their lives, but only 35-58 percent of the comparison group held these beliefs. On the other hand, women in the comparison group were more likely than those in the sterilization group to believe that sterilization has negative health and psychological effects--for example, changes in menses (more bleeding or cramping) or defeminization. The beliefs held by both groups suggest that it is a conviction regarding the advantages of sterilization, rather than a relative unawareness of the disadvantages, that distinguishes women who plan to be sterilized from those who, although they want no more children, do not have similar plans. The study results have implications for family planning professionals: Counselors need to be aware that some women seeking sterilization may not understand its permanency or may have an unrealistic appraisal of its potential effect on their lives.(ABSTRACT TRUNCATED AT 250 WORDS)

Determinants of early implant discontinuation among low-income women.

The determinants of contraceptive implant discontinuation within six months of insertion were examined among 786 low-income women attending family planning clinics in three U.S. cities. The six-month cumulative life-table discontinuation rate was 7.6%. Menstrual side effects were the most common reasons given for early implant removal, although women who discontinued use were no more likely than those who continued with the method to report menstrual irregularities. Women who opted for early removal were more likely than those who continued with the method to experience headaches, hair loss, weight gain and arm infection. Logistic regression analysis indicates that dissatisfaction with prior contraceptive methods, a partner who wants a child within the next two years, perceived pressure from health care providers to choose the implant, exposure to negative media coverage and the number of implant side effects significantly predict early implant discontinuation. Women's social and demographic characteristics, Medicaid status and motivation to avoid an unplanned pregnancy were not significantly related to early removal.

Condom use among women choosing long-term hormonal contraception.

CONTEXT: Women who rely on long-term hormonal contraception may neglect to use condoms, and thus increase their risk of contracting sexually transmitted diseases, including AIDS. METHODS: Data from a prospective, multisite study were collected to examine the probability of condom use among 1,073 new users of either the contraceptive implant or injectable; users were interviewed when they accepted their method and again six months to one year later. Multivariate logistic regression analyses identified factors that significantly predicted the likelihood of dual method use. RESULTS: Condom use dropped markedly among women who adopted long-term hormonal contraception. The proportion who always used condoms in the previous three months fell from 21% at the time of adoption to 11% at follow-up. Among women with one sexual partner, this decrease was from 20% to 10%; however, among those with more than one partner, use increased from 25% to 31%. The factors significantly predicting dual method use included previous condom use (odds ratio of 2.5), receipt of AIDS-specific counseling (odds ratio of 1.6), the perception of being at some risk of AIDS at baseline (odds ratio of 1.4) and having had more than one sexual partner over the study period (odds ratio of 5.4). In addition, injectable users, teenagers and black women were more likely than other women to use condoms with their hormonal method. CONCLUSIONS: Although condom use among all women declined markedly once they initiated long-term hormonal contraception, frequency of condom use varied by subgroup and was associated with several factors. Most importantly, women with more than one sexual partner and those who received a message during counseling on the need to continue using condoms were more likely than others to use condoms in conjunction with the implant or injectable.
