Association of Pharmacist Prescription With Dispensed Duration of Hormonal Contraception.

ABSTRACT: Importance:Since 2016, 11 states have expanded the scope of pharmacists to include direct prescription of hormonal contraception. Dispensing greater than 1 month's supply is associated with improved contraceptive continuation rates and fewer breaks in coverage. Scant data exist on the practice of pharmacist prescription of contraception and its outcomes compared with traditional, clinic-based prescriptions. Objective:To compare the amount of hormonal contraceptive supply dispensed between pharmacists and clinic-based prescriptions. Prescribing patterns were assessed by describing prescribing practices for women with contraindications to combined hormonal contraception. Characteristics of women seeking hormonal contraception directly from pharmacists were also described. Design, Setting, and Participants:This cohort study surveyed women aged 18 to 50 years who presented to pharmacies in California, Colorado, Hawaii, and Oregon for hormonal contraception prescribed by a clinician or a pharmacist between January 30 and November 1, 2019. Exposures:Pharmacist or clinic-based prescription of contraception. Main Outcomes and Measures:Months of contraceptive supply dispensed. Results:Four hundred ten women (mean [SD] age, 27.1 [7.7] years) were recruited who obtained contraception directly from a pharmacist (n?=?144) or by traditional clinician prescription (n?=?266). Women obtaining contraception from a pharmacist were significantly younger (82 [56.9%] vs 115 [43.2%] participants aged 18-24 years; P?=?.03), had less education (38 [26.4%] vs 100 [37.6%] with a bachelor degree; P?=?.002), and were more likely to be uninsured (16 [11.1%] vs 8 [3.0%] participants; P?=?.001) compared with women with a prescription from a clinician. Pharmacists were significantly more likely to prescribe a 6-month or greater supply of contraceptives than clinicians (6.9% vs 1.5%, P?

Project description:ImportanceThe incidence of central nervous system (CNS) tumors in children appears to be increasing, yet few risk factors are established. There is limited information regarding whether maternal hormonal contraception use increases this risk.ObjectiveTo examine the association between maternal hormonal contraception use and CNS tumors in children (<20 years).Design, setting, and participantsIn this nationwide cohort study based on population-based registry data, 1 185 063 children born in Denmark between January 1, 1996, and December 31, 2014, were followed up for a diagnosis of a CNS tumor (final follow-up on December 31, 2018).ExposuresMaternal hormonal contraception use was analyzed according to any use, regimen (combined/progestin only), and route of administration (oral/nonoral), categorized as recent use (≤3 months before start and during pregnancy), previous use (>3 months before start of pregnancy), and no use. For injections, implants, and intrauterine devices that are used for a different time period, the categorization was appropriately altered.Main outcomes and measuresHazard ratio (HR) and incidence rate difference (IRD) of CNS tumors diagnosed at younger than 20 years.ResultsAfter 15 335 990 person-years of follow-up (mean follow-up, 12.9 years), 725 children were diagnosed with a CNS tumor. The mean age at diagnosis was 7 years, and 342 (47.2%) of the diagnosed children were female. The adjusted incidence rate of CNS tumors per 100 000 person-years was 5.0 for children born to mothers with recent hormonal contraception use (n = 136 022), 4.5 for children born to mothers with previous use (n = 778 843), and 5.3 for children born to mothers with no use (n = 270 198). The corresponding HRs were 0.95 ([95% CI, 0.74-1.23]; 84 children with CNS tumors; IRD, -0.3 [95% CI, -1.6 to 1.0]) for recent use and 0.86 ([95% CI, 0.72-1.02]; 421 children with CNS tumors; IRD, -0.8 [95% CI, -1.7 to 0.0]) for previous use, compared with no use. No statistically significant associations were found for recent or previous use of oral combined, nonoral combined, oral progestin only, or nonoral products compared with no use of hormonal contraception.Conclusions and relevanceAmong Danish children, there was no statistically significant association between any maternal hormonal contraception use and CNS tumor risk.

Project description:ObjectivesTo investigate the association between contemporary combined hormonal contraceptives (including progestogen types in combined preparations and all progestogen-only products) and overall and specific types of ovarian cancer.DesignProspective, nationwide cohort study.SettingDenmark, 1995-2014.ParticipantsAll women aged 15-49 years during 1995-2014 were eligible. Women were excluded if they immigrated after 1995, had cancer (except non-melanoma skin cancer), had venous thrombosis, or were treated for infertility before entry (final study population included 1?879?227 women). Women were categorised as never users (no record of being dispensed hormonal contraception), current or recent users (?1 year after stopping use), or former users (>1 year after stopping use) of different hormonal contraceptives.Main outcome measuresPoisson regression was used to calculate relative risk of ovarian cancer among users of any contemporary combined hormonal contraceptives and by progestogen type in combined preparations and all progestogen-only products, including non-oral preparations. Separate analyses examined women followed up to their first contraception type switch and those with full contraceptive histories. Duration, time since last use, and tumour histology were examined and the population prevented fraction were calculated.ResultsDuring 21.4 million person years, 1249 incident ovarian cancers occurred. Among ever users of hormonal contraception, 478 ovarian cancers were recorded over 13?344?531 person years. Never users had 771 ovarian cancers during 8?150?250 person years. Compared with never users, reduced risks of ovarian cancer occurred with current or recent use and former use of any hormonal contraception (relative risk 0.58 (95% confidence interval 0.49 to 0.68) and 0.77 (0.66 to 0.91), respectively). Relative risks among current or recent users decreased with increasing duration (from 0.82 (0.59 to 1.12) with ?1 year use to 0.26 (0.16 to 0.43) with >10 years' use; P<0.001 for trend). Similar results were achieved among women followed up to their first switch in contraceptive type. Little evidence of major differences in risk estimates by tumour type or progestogen content of combined oral contraceptives was seen. Use of progestogen-only products were not associated with ovarian cancer risk. Among ever users of hormonal contraception, the reduction in the age standardised absolute rate of ovarian cancer was 3.2 per 100?000 person years. Based on the relative risk for the never use versus ever use categories of hormonal contraception (0.66), the population prevented fraction was estimated to be 21%-that is, use of hormonal contraception prevented 21% of ovarian cancers in the study population.ConclusionsUse of contemporary combined hormonal contraceptives is associated with a reduction in ovarian cancer risk in women of reproductive age-an effect related to duration of use, which diminishes after stopping use. These data suggest no protective effect from progestogen-only products.
