A Web-Based Decision Tool to Improve Contraceptive Counseling for Women With Chronic Medical Conditions: Protocol For a Mixed Methods Implementation Study

BACKGROUND

Women with chronic medical conditions, such as diabetes and hypertension, have a higher risk of pregnancy-related complications compared with women without medical conditions and should be offered contraception if desired. Although evidence based guidelines for contraceptive selection in the presence of medical conditions are available via the United States Medical Eligibility Criteria (US MEC), these guidelines are underutilized. Research also supports the use of decision tools to promote shared decision making between patients and providers during contraceptive counseling.

OBJECTIVE

The overall goal of the MiHealth, MiChoice project is to design and implement a theory-driven, Web-based tool that incorporates the US MEC (provider-level intervention) within the vehicle of a contraceptive decision tool for women with chronic medical conditions (patient-level intervention) in community-based primary care settings (practice-level intervention). This will be a 3-phase study that includes a predesign phase, a design phase, and a testing phase in a randomized controlled trial. This study protocol describes phase 1 and aim 1, which is to determine patient-, provider-, and practice-level factors that are relevant to the design and implementation of the contraceptive decision tool.

METHODS

This is a mixed methods implementation study. To customize the delivery of the US MEC in the decision tool, we selected high-priority constructs from the Consolidated Framework for Implementation Research and the Theoretical Domains Framework to drive data collection and analysis at the practice and provider level, respectively. A conceptual model that incorporates constructs from the transtheoretical model and the health beliefs model undergirds patient-level data collection and analysis and will inform customization of the decision tool for this population. We will recruit 6 community-based primary care practices and conduct quantitative surveys and semistructured qualitative interviews with women who have chronic medical conditions, their primary care providers (PCPs), and clinic staff, as well as field observations of practice activities. Quantitative survey data will be summarized with simple descriptive statistics and relationships between participant characteristics and contraceptive recommendations (for PCPs), and current contraceptive use (for patients) will be examined using Fisher exact test. We will conduct thematic analysis of qualitative data from interviews and field observations. The integration of data will occur by comparing, contrasting, and synthesizing qualitative and quantitative findings to inform the future development and implementation of the intervention.

RESULTS

We are currently enrolling practices and anticipate study completion in 15 months.

CONCLUSIONS

This protocol describes the first phase of a multiphase mixed methods study to develop and implement a Web-based decision tool that is customized to meet the needs of women with chronic medical conditions in primary care settings. Study findings will promote contraceptive counseling via shared decision making and reflect evidence-based guidelines for contraceptive selection.

The intrauterine device in modern contraception: Still an actuality?

The intrauterine devices (IUD) is a contraceptive method largely used as an effective, safe and economic method of contraception; IUD efficacy is demonstrated to be about 97%, and copper IUD contraceptive failure frequency is about 0.8% for the first year of use, and this is about 0.1-0.2% for the progestin IUD. IUD benefits are different; it produces a well-defined contraceptive efficacy for long time, is useful for sexual activity and is rather free from common problems. However, IUD utilization is associated with an increasing risk of pelvic infection (0.5%) in the 8 years from initial use, and the common risk of pelvic inflammatory infection (PID) is about one to two cases per year; this risk, for copper IUD users, is 0.2-0.5% per year. The possible side effects of IUD use are: pelvic pain, irregular meshes, infections, bleeding and uterine perforation; we report a uterine perforation due to IUD migration in the Retzius space, diagnosed on transvaginal ultrasonography, confirmed on CT and removed by laparoscopy. In any case, the IUD remains the mainstay of family planning measures in developing countries but, unfortunately, its association with possible serious complications, change the cost-benefit link and restrict its utilization by a large part of the general population.

Effect of a low-dose oral contraceptive on venous endothelial function in healthy young women: preliminary results

BACKGROUND

A possible increase in the incidence of venous thromboembolic events has been reported among users of third generation oral contraceptives. The objective of this study was to evaluate the effect of a low dose oral contraceptive (15 microg ethinyl estradiol/60 microg gestodene) on the venous endothelial function of healthy young women.

METHODS

Prospective case control study using the dorsal hand vein technique. Venous endothelial function was evaluated at baseline and after 4 months in the oral contraceptive users group (11 women) and in a control group (9 women). After preconstriction of the vein with phenylephrine, dose-response curves for acetylcholine and sodium nitroprusside were constructed.

RESULTS

In the contraceptive users group, a reduction occurred in the maximum venodilation response to acetylcholine and sodium nitroprusside after 4 months of oral contraceptive use, but this difference was not statistically significant (P > 0.05). No significant changes were detected in maximum venodilation responses to acetylcholine and sodium nitroprusside at the 4-month time point in the control group.

CONCLUSION

This study found no significant impairment of endothelium-dependent or independent venodilation in healthy young women following oral contraceptive use. Further studies are necessary using the same methodology in a larger sample over a longer follow-up period.

The intrauterine contraceptive device

The intrinsic appeal of the convenience and effectiveness of the IUD has increased interest in these devices in the United States in recent years. Understanding the uniqueness of the Dalkon Shield experience and applying the lessons learned about appropriate candidate selection should continue to reduce any lingering liability concerns. One lawsuit has been filed against the copper IUD in the 12 years that it has been available in the United States. If legislation requiring insurance coverage for IUDs and other prescription contraceptive agents continues to be passed by more states, the use of IUDs will continue to grow. The introduction of new IUDs with different side-effect profiles will expand the number of US women who can and will be interested in using this method of birth control.
