Hormonal contraceptive use in Australian women: Who is using what?

BACKGROUND: In Australia many hormonal contraceptives are not Pharmaceutical Benefits Scheme (PBS) supported, hence the use of different formulations have not been quantified. OBJECTIVES: To document the use of hormonal contraceptives and factors associated with their use. MATERIALS AND METHODS: Cross-sectional, online questionnaire-based study of 6986 Australian women, aged 18-39 years, recruited by email invitation from two large, representative databases. Main outcome measures were the prevalence of use of hormonal contraceptives and associated socio-demographic characteristics. RESULTS: Of the 6600 potential hormone contraceptive users, 43.2% were current users. Most (63.6%) reported using a combined oral contraceptive (COC) of which 30.9% were non-PBS-supported anti-androgenic progestin-containing COCs. Use of long-acting reversible contraceptives (LARC) or an injectable contraceptive was reported by 26.8%. Education beyond secondary school, being Australian born, rural residency, normal body mass index, age <25 years and nulliparity were significantly associated with hormonal contraceptive use. Women who reported polycystic ovary syndrome or acne were more likely to be taking a third or fourth generation COC (P < 0.0001) and endometriosis was significantly associated with intrauterine system (IUS) use. Third or fourth generation COC use was reported by 12.1% of obese, current smokers. CONCLUSION: An estimated one-third of Australian women aged 18-39 are taking a non-PBS-supported anti-androgenic progestin COC, highlighting inequity in access to COC options. That hormonal contraceptive use is higher in rural areas is a novel finding and the proportion of LARC or injectable use suggests that uptake in Australia is higher than previously reported.

The Quality of Information on Combined Oral Contraceptives Available on the Internet.

OBJECTIVE: Combined oral contraceptives (COC) are a popular choice among women. The Internet is an accessible and popular source of information on contraception. The objective of this study was to evaluate the quality of online information on COC. METHODS: A quantitative content analysis was completed on websites containing patient health information on COCs. The search was completed in October 2016 using Google; search terms included "birth control pill," "oral contraception," "oral birth control", "birth control," and "pregnancy prevention." The first three pages of search results were screened according to inclusion criteria. The DISCERN instrument and JAMA Benchmarks were used to assess quality. Websites were analyzed independently by two coders; discrepancies were resolved by third coder (Canadian Task Force Classification III). RESULTS: Of the 155 websites identified, 32 were eligible for review. Most websites mentioned contraceptive benefit (81.3%), and half reported the typical effectiveness of COCs (53.1%). Commonly included non-contraceptive benefits were alleviation of dysmenorrhea (87.5%) and reduced blood loss (84.4%). Risk of venous thromboembolism was listed in 81.3% of websites, including stroke (56.3%) and myocardial infarction (46.9%); however, sites failed to include details with these risks. Only 46.9% provided information on starting COC; the first-day start method was the most common (40.6%). Nearly half lacked details on managing missed pills (46.9%). The mean Flesch-Kincaid Grade Level was 9 ± 2.0. The mean DISCERN score was 46.3 ± 9.37, indicating "fair" quality. CONCLUSION: Online information on COCs was variable in quality, often missing key information for making informed decisions. Health care providers should be aware of information gaps when advising women to seek information online.

Use of simulated patients to evaluate combined oral contraceptive dispensing practices of community pharmacists.

BACKGROUND: Combined oral contraceptive (COC) use is the most commonly used reversible method of birth control. The incorrect use of COCs is frequent and one of the most common causes of unintended pregnancies. Community pharmacists (CPs) are in a strategic position to improve COC use because they are the last health professional to interact with patients before drug use. OBJECTIVE: To evaluate the COC dispensing practices of CPs in a developing country. METHOD: A cross-sectional study was conducted in community pharmacies of Assis and Ourinhos microregions, Brazil, between June 1, 2012, and October 30, 2012. Four simulated patients (SPs) (with counseled audio recording) visited community pharmacies with a prescription for Ciclo 21(®) (a COC containing ethinyl estradiol 30 mcg + levonorgestrel 15 mcg). The audio recording of every SP visit was listened to independently by 3 researchers to evaluate the COC dispensing practice. The percentage of CPs who performed a screening for safe use of COCs (i.e., taking of patients' medical and family history, and measuring of blood pressure) and provided counseling, as well as the quality of the screening and counseling, were evaluated. RESULTS: Of the 185 CPs contacted, 41 (22.2%) agreed to participate in the study and finished the study protocol. Only 3 CPs asked the SP a question (1 question asked by each professional), and all of the questions were closed-ended, viz., "do you smoke?" (n = 2) and "what is your age?" (n = 1). None of the CPs measured the patient's blood pressure. Six CPs provided counseling when dispensing COCs (drug dosing, 5 CPs; possible adverse effects, 2 CPs), and one CP provided counseling regarding both aspects. CONCLUSION: The CPs evaluated did not dispense COC appropriately and could influence in the occurrence of negatives therapeutic outcomes such as adverse effects and treatment failure.

Current issues and available options in combined hormonal contraception.

Development of hormonal contraception marked a revolutionary step in social change that has improved the lives of women and families worldwide. Since the first oral contraceptive was introduced in the 1960s, hormonal contraception has undergone various stages of advancement. Today, oral contraceptive regimens are safer and more tolerable, with equal or improved efficacy, than the early formulations. Incremental decreases in the dose of estrogens have helped to alleviate some of the unwanted estrogenic side effects of combined hormonal contraceptives. Progestogens have also evolved over time, and newer generations of progestins have minimal side effects. New delivery methods have further extended the range of options available to women. Among these, the transdermal patch and vaginal ring are widely used. This review examines available combined hormonal contraceptive options and compares them, where data are available, for efficacy, safety, cycle control, adverse events profiles and associated risks, and user preference and satisfaction. We also examine particular areas of interest, including bone mineral density, venous thrombosis and use of antiepileptic drugs.

Comparison of diaphragm and combined oral contraceptive pill users in the Australian family planning setting.

OBJECTIVES: To determine the number of women fitted with a diaphragm or cervical cap at family planning clinics across the Australian State of New South Wales (NSW) from 2000 to 2005. To compare the demographic characteristics of women fitted with this form of contraceptive with women prescribed the combined oral contraceptive pill (COCP). METHOD: An audit of women presenting for contraceptive services between 2000 and 2005 was undertaken. The demographic characteristics of women fitted with a barrier method or prescribed the COCP between 1st April, 2002, and 31st October, 2004, were obtained from the Family Planning NSW Activity Data Set (FADS). RESULTS: The proportion of women fitted with a diaphragm or cap remained constant between 2001 and 2005 at approximately 5%. During the 31 months that the study period lasted, 793 women were fitted with a diaphragm or cervical cap compared with 8047 women prescribed the COCP during the same time frame (including 76 women who received both a diaphragm and COCP prescription during this period). Women fitted with the barrier contraceptive were significantly more likely to be older, to have received a tertiary level education and to have private health insurance than their counterparts prescribed the COCP. They were less likely to come from a non-English speaking background. DISCUSSION: The diaphragm and cervical cap are viable contraceptive methods for a specific group of older, well-educated women. The possible benefits of female-controlled barrier devices in the prevention of sexually transmissible infections may result in a wider demographic use in the future.

Use of oral contraceptives and hormone replacement therapy in the WHO MONICA project.

AIMS: To compare menopausal age and the use of oral contraceptives (OC) and hormonal replacement therapy (HRT) between the 32 populations of the WHO MONICA Project, representing 20 different countries. METHODS: Using a uniform protocol, age at menopause and the use of OC and HRT was recorded in a random sample of 25-64 year-old women attending the final MONICA population cardiovascular risk factor survey between 1989 and 1997. A total of 39,120 women were included. RESULTS: There were wide variations between the populations in the use of OC and HRT. The use of OC varied between 0 and 52% in pre-menopausal women aged 35-44 years, Central and East Europe and North America having the lowest and West Europe and Australasia the highest prevalence rates. Among post-menopausal women between 45 and 64 years, the prevalence of HRT use varied from 0 to 42%. In general, the use of HRT was high in Western and Northern Europe, North America and Australasia and low in Central, Eastern and Southern Europe and China. With the exception of Canada (45 years), the mean age at menopause differed only little (ranging from 48 to 50 years) between the populations. CONCLUSION: The use of OC and HRT varies markedly between populations, in general following a regional pattern. Whereas, the prevalence rates are mostly similar within a country, there are remarkable differences even between neighbouring countries, reflecting nation-specific medical practice and public attitudes that are not necessarily based on scientific evidence.

The role of emergency contraception.

Emergency contraception is an underused therapeutic option for women in the event of unprotected sexual intercourse. Available postcoital contraceptives include emergency contraceptive pills (ECPs) both with and without estrogen, and copper-bearing intrauterine devices. Each method has its individual efficacy, safety, and side effect profile. Most patients will experience prevention of pregnancy, providing they follow the treatment regimen carefully. There are concerns that women who use ECPs may become lax with their regular birth control methods; however, reported evidence indicates that making ECPs more readily available would ultimately reduce the incidence of unintended pregnancies. In addition, it is typically conscientious contraceptive users who are most likely to seek emergency treatment. Patient education is paramount in the reduction of unintended pregnancies and there are numerous medical resources available to women to assist them in this endeavor. Finally, ECPs are associated with financial and psychologic advantages that benefit both the individual patient and society at large.

Advanced provision of emergency contraception does not reduce abortion rates.

A number of small studies have demonstrated increased use of emergency contraception (EC) when women have a supply available at home. It has been suggested that widespread use of EC could reduce abortion rates. We undertook a community intervention study designed to determine whether offering advanced supplies of EC to large numbers of women influenced abortion rates. All women aged between 16 and 29 years living in Lothian, Scotland, were offered, through health services, five courses of EC without cost to keep at home. Of a population of around 85,000 women in this age group, the study showed that an estimated 17,800 women took a supply of EC home and over 4500 of them gave at least one course to a friend. It was found that nearly half (45%) of women who had a supply used at least one course during the 28 months that the study lasted. In total, an estimated 8081 courses of EC were used. EC was used within 24 h after intercourse on 75% of occasions. Abortion rates in Lothian were compared with those from three other health board areas of Scotland. No effect on abortion rates was demonstrated with advanced provision of EC. The results of this study suggest that widespread distribution of advanced supplies of EC through health services may not be an effective way to reduce the incidence of unintended pregnancy in the UK.

The North Carolina DIAL EC project: increasing access to emergency contraceptive pills by telephone.

OBJECTIVES: To evaluate a telephone prescription service designed to increase access to emergency contraceptive pills (ECPs) in North Carolina. METHODS: Women who wanted ECPs called a toll-free number and were screened over the telephone. Prescriptions were faxed to pharmacies chosen by callers. RESULTS: In 29 months, the service issued 9745 prescriptions to 7774 callers. Forty percent of callers were teens. Only 16% of callers received more than one prescription. Most callers heard about the service through referrals from Planned Parenthood staff and word-of-mouth. CONCLUSIONS: This service was successful in providing prompt access to ECPs to women throughout the state. Frequent use of the service by individual women was uncommon. Callers preferred to obtain ECPs from local pharmacies rather than from Planned Parenthood health centers, despite generally higher prices at pharmacies.

Clinical performance of a levonorgestrel-releasing intrauterine system and oral contraceptives in young nulliparous women: a comparative study.

This 1-year randomized study was carried out at family-planning clinics of two university hospitals to compare the safety and acceptability of a levonorgestrel-releasing intrauterine system (LNG IUS) and oral contraceptives (OCs) in young nulliparous women. The study population consisted of 200 women aged 18-25 years seeking contraception. Ninety-four women entered the LNG IUS group and 99 entered the OC group. Continuation rates, reasons leading to discontinuation, adverse events, menstrual questionnaires, subjective well-being and sexual behavior were evaluated. Nineteen women (20%) in the LNG IUS group discontinued the study during the 1-year observation period, and 27 discontinued (27%) in the OC group. The most common reason (31%) for discontinuation in the IUS group was pain. In the OC group, hormonal side effects were the predominant medical reason for study termination. The safety and acceptability of the LNG IUS for contraception was observed to be as good as with OCs, with a high continuation rate.

Do Mexico City pharmacy workers screen women for health risks when they sell oral contraceptive pills over-the-counter?

CONTEXT: In Mexico, oral contraceptives (OCs) are available to women over-the-counter in pharmacies. While past research has suggested that nonmedical providers, such as pharmacy workers, are capable of screening women for contraindications to OCs, little is known about their practices. METHODS: After selecting a 10% random sample of all pharmacies in Mexico City (n = 108), we surveyed the first available pharmacy worker to learn more about pharmacy workers' screening practices when selling OCs over-the-counter to women. RESULTS: While nearly all of the pharmacy workers surveyed had sold OCs without a prescription, only 31% reported asking women any questions before selling pills. Among those who asked questions, the most commonly asked questions were about other medications a woman was taking, about blood pressure and about alcohol intake. Pharmacy workers did not ask these questions consistently to all clients. CONCLUSION: Training pharmacy workers might be one strategy to improve screening of women for pill contraindications. However, pharmacy workers may lack the time and motivation to carry out such screening. An alternative strategy might be to better inform women to self-screen for pill contraindications.

Emergency contraceptive pills over-the-counter: a population-based survey of young Swedish women.

One year after emergency contraceptive pills (ECP) had become prescription-free, we sent a questionnaire to 800 randomly selected women in mid-Sweden. The aim was to investigate women's knowledge, attitudes and practices regarding the method. The response rate was 71% (n = 564). The majority of the women, 65%, would prefer to purchase ECP over-the-counter (OTC) in a pharmacy. Attitudes toward the method were predominantly positive, but one fourth (24%) had worries about side effects and one third (33%) considered ECP to be a kind of abortion. Logistic regression showed that correct knowledge of and positive attitudes toward ECP contributed to estimated future use of ECP. Although women favored the OTC option, persistent misunderstanding about ECP implies that routine information from gynecologists and health professionals as well as media campaigns is needed along with the deregulation in order to make ECP an accepted and properly used contraceptive method.

Recruitment strategies. Pharmacists' participation in an evaluation project to dispense emergency contraception.

The objective of this article was to describe the effectiveness of a multifocus recruitment strategy to a pilot project allowing direct provision of emergency contraception (EC) in a community pharmacy through collaborative agreements between pharmacists and physicians. The project recruited pharmacies through direct appeals to pharmacists, pharmacy managers and/or owners, and corporate pharmacy chains. The evaluation project was successful in recruiting sufficient numbers of pharmacies to warrant proceeding with the project. The most successful component of the recruitment strategy was reference to the opportunities that participation offered to expand the pharmacist's role in patient-focused care. The importance of peer influence was also noted in terms of encouraging pharmacy involvement.

Out-of-pocket expenditures for oral contraceptives and number of packs per purchase.

OBJECTIVE: Two potential barriers to use of oral contraceptives (OCPs) are out-of-pocket expenditures and the inconvenience of monthly pharmacy visits. This study used nationally representative data to examine the out-of-pocket costs of OCPs and whether women obtain more than 1 pack per purchase. METHODS: We used data from the 1996 Medical Expenditure Panel Survey. Dependent variables were out-of-pocket expenditures per pack and the number of packs obtained per purchase. Chi2 tests were used to examine the bivariate relationships between the dependent variables and covariates. Regression analyses were used to examine the predictors of OCP expenditures and the number of packs obtained per purchase. RESULTS: Women paid an average of 14 dollars per pack of OCPs, and 73% obtained only 1 pack per purchase. On average, privately insured women paid 60% of the total expenditures for OCPs. Women who had no prescription drug coverage, who were uninsured, or who were privately insured but not in managed care plans had higher out-of-pocket expenditures. Women who were without prescription drug coverage or who were in managed care plans were more likely to obtain only 1 pack per purchase. CONCLUSION: Out-of-pocket costs and dispensing restrictions may be barriers to consistent use of OCPs. Women's health care providers should consider options to overcome these barriers, such as the use of mail order prescription services.

Emergency contraception: pharmacy access in Albuquerque, New Mexico.

OBJECTIVE: Emergency contraception could reduce the approximately 3 million unintended pregnancies that occur annually in the United States. Dedicated emergency contraception products may be particularly useful because instructions are easy to understand and simple to follow. However, they must be available within a few days to women who have had unprotected intercourse. The goal of this study was to investigate whether women presenting to pharmacies in a moderately sized metropolitan area with a prescription for Plan B or Preven could get it filled. METHODS: Two research assistants posed as women needing emergency contraception. They visited 89 pharmacies in Albuquerque, New Mexico, presenting a prescription for either Plan B or Preven. The assistants recorded the availability of the products in the pharmacies. When the product was not in stock, the research assistants asked pharmacy providers why the products were not carried. Fisher exact test was performed to compare categoric data. RESULTS: Plan B and Preven were in stock at only 19 visits (11%). Of the pharmacies that did not stock the products, 53% reported they could obtain Plan B or Preven within 24 hours. The most common reason cited by pharmacy providers for not stocking Plan B or Preven was the lack of prescriptions received for them (65%). CONCLUSION: Plan B and Preven were not in stock at the majority of pharmacies in a moderately sized metropolitan area. Lack of availability at the pharmacy constitutes a major barrier to emergency contraception access.

Providing emergency contraceptive pills "behind-the-counter": opinions among Minnesota healthcare providers.

We assessed strategies to increase access to emergency contraceptive pills (ECPs) among healthcare providers in Minnesota. We hypothesized that physicians, mid-level practitioners (nurse practitioners, certified nurse midwives and physician assistants) and pharmacists would support collaborative drug therapy agreements to enable pharmacist provision of ECPs without a prescription ("behind-the-counter"). We assessed these and other strategies to improve access to ECPs among a random sample of 1000 healthcare providers using mailed surveys. Obtaining a 50% response rate (n = 495), we discovered that the majority of total respondents (and a significant proportion of physicians) favored improving ECP availability "behind-the-counter", over-the-counter or both. Support among mid-level practitioners was more guarded: 39% of respondents supported pharmacist provision of ECPs and more than 20% wanted more information. Among pharmacists, 46% said they would participate in a collaborative protocol for provision of ECPs. Results demonstrate the degree of support and illuminate potential obstacles to pharmacist-provided ECPs. While there is general support among Minnesota providers regarding ECPs, a campaign to educate providers about recent scientific data on ECPs and collaborative drug therapy agreements should be initiated.
