Introduction:

Immediate postpartum long-acting reversible contraception (IPP-LARC) after delivery may decrease rapid repeat pregnancy (RRP). RRP is associated with preterm birth, small for gestational age, low birth weight, and infant/maternal mortality. In April 2017, the Ohio legislature passed SB 332, mandating immediate postpartum LARC coverage. Later that year, our hospital made the IPP-LARC Nexplanon (and not intrauterine devices [IUDs]) available to all delivering patients. This study aimed to see if SB 332 is associated with decreased RRP.

Methods:

Using electronic health record and state registry data, we examined sociodemographic and perinatal care variables for 726 pregnant adolescents and adults delivering at our hospital during the 12 months before and after IPP-LARC became available. We then determined the association between RRP and these variables.

Results:

After LARC became available, 62/368 patients chose Nexplanon. Gravidity (OR: 1.128) and vaginal delivery (OR: 1.682) were negatively associated with RRP while age at delivery was inversely associated (OR: 0.902, p < .001). The adjusted mean probability of RRP was 6% for those who had IPP-LARC placement, compared with 20% for those who did not. LARC availability was positively associated with RRP but not significantly (OR: 1.287, p = .195).

Conclusions:

After SB 332's passage, IPP-LARC availability was positively associated with RRP, but the percentage of patients who chose IPP-LARC was low. However, RRP occurred less often among patients who chose IPP-LARC placement. Hospital systems must actively invest in patient education and provider support to ensure interventions to reduce rapid repeat pregnancy are optimally utilized by vulnerable populations.

Birth Control Methods

Birth Control Methods

Vasectomy is a surgical form of male sterilization that involves severing and sealing the vasa deferentia, preventing sperm from mixing with semen during ejaculation. Because a vasectomy does not impact the testes' ability to produce testosterone, hormone levels, libido, and sexual function generally remain unchanged. While vasectomy is highly effective in preventing pregnancy, with a success rate near 99.85%, rare cases of recanalization (spontaneous reconnection) can occur. Although...

Local Anesthetics: Clinical Application as Epidural Anesthesia

Local Anesthetics: Clinical Application as Epidural Anesthesia

Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

Regression Toward the Mean

Regression Toward the Mean

Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

Drug Product Performance: In Vitro–In Vivo Correlation

Drug Product Performance: In Vitro–In Vivo Correlation

In pharmaceutical development, it's crucial to establish a predictive in vitro–in vivo correlation (IVIVC) for two or more formulations to gain a comprehensive understanding of release properties. IVIVC reduces the need for costly in vivo studies and facilitates the establishment of meaningful dissolution specifications with significant cost savings and decreased regulatory burden. Furthermore, a meaningful IVIVC should predict Cmax and AUC within 20%, aligning with FDA guidance while...

Desensitization and Tachyphylaxis

Desensitization and Tachyphylaxis

Tachyphylaxis is described as a rapid decrease in response to a drug after repeated or continuous administration of the same drug dose. It is a phenomenon where the body becomes less responsive to a particular substance or intervention over time, requiring higher doses or stronger interventions to achieve the same effect. It results from adaptive changes in the body's receptors, signaling pathways, or physiological processes that occur in response to prolonged exposure to a stimulus.
