Free-of-charge long-acting reversible contraception: two-year discontinuation, its risk factors, and reasons.

BACKGROUND: Since 2013, the residents of the city of Vantaa, Finland, have been offered their first long-acting reversible contraceptive method (levonorgestrel-releasing intrauterine system, implant, and copper intrauterine device) free of charge. OBJECTIVE: The primary aim of this study was to assess the 2-year cumulative discontinuation rates of long-acting reversible contraceptive methods when provided free of charge for first-time users in a real-world setting. Additional aims were to describe factors associated with discontinuation and to evaluate the reasons for discontinuation. STUDY DESIGN: This is a retrospective register-based cohort study of 2026 nonsterilized women aged 15 to 44 years, who initiated a free-of-charge long-acting contraceptive method in 2013-2014 in the city of Vantaa. Removals within 2 years after method initiation and reasons for discontinuation were obtained from electronic health records and from national registers. We calculated the 2-year cumulative incidence rates of discontinuation with 95% confidence intervals for each method. Furthermore, we assessed crude and adjusted incidence rate ratios of discontinuation with 95% confidence interval by Poisson regression models comparing implants and copper intrauterine device with levonorgestrel-releasing intrauterine systems. RESULTS: During the 2 -year follow-up, 514 women discontinued, yielding a cumulative discontinuation rate of 28.3 per 100 women-years (95% confidence interval, 26.2-30.4). Among the 1199 women who initiated the levonorgestrel-releasing intrauterine system, the cumulative discontinuation rate was 24.2 per 100 women-years (95% confidence interval, 21.7-26.9); among the 642 implant users, 33.3 per 100 women-years (95% confidence interval, 29.5-37.4); and among the 185 copper intrauterine device users, 37.8 per 100 women-years (95% confidence interval, 31.0-45.7). Compared with women aged 30 to 44 years, women aged 15 to 19 years (adjusted incidence rate ratio, 1.58; 95% confidence interval, 1.17-2.14) and 20 to 29 years (adjusted incidence rate ratio, 1.35; 95% confidence interval, 1.11-1.63) were more likely to discontinue. We observed a higher discontinuation rate in women who had given birth within the previous year (adjusted incidence rate ratio, 1.36; 95% confidence interval, 1.13-1.65), spoke a native language other than Finnish or Swedish (adjusted incidence rate ratio, 1.31; 95% confidence interval, 1.06-1.63), and had a history of a sexually transmitted infection (adjusted incidence rate ratio, 1.62; 95% confidence interval, 1.07-2.46). No association was found in marital status, overall parity, history of induced abortion, socioeconomic status, education level, or smoking status. The most common reason for discontinuation was bleeding disturbances, reported by 21% of women who discontinued the levonorgestrel-releasing intrauterine system, by 71% who discontinued the implant, and by 41% who discontinued the copper intrauterine device. One in 4 women who discontinued the copper intrauterine device reported heavy menstrual bleeding, whereas only 1% who discontinued the levonorgestrel-releasing intrauterine system and none who discontinued implants reported this reason. Abdominal pain was the reported reason for discontinuation in 20% of both intrauterine device users and in only 2% who discontinued implants. CONCLUSION: At 2 years, the use of implants and copper intrauterine devices was more likely to be discontinued than that of the levonorgestrel-releasing intrauterine system. Women younger than 30 years and those who gave birth in the preceding year, spoke a native language other than Finnish or Swedish, or had a history of sexually transmitted infections were more likely to discontinue. The levonorgestrel-releasing intrauterine system was least likely to be removed owing to bleeding disturbances.

Projecting the fiscal impact of South Africa's contraceptive needs: Scaling up family planning post 2020.

BACKGROUND: Evidence-informed priority setting is vital to improved investment in public health interventions. This is particularly important as South Africa (SA) makes the shift to universal health coverage and institution of National Health Insurance. OBJECTIVES: To measure the financial impact of increasing the demand for modern contraceptive methods in the SA public health sector. We estimated the total cost of providing contraceptives, and specifically the budgetary impact of premature removals of long-acting reversible contraceptives. METHODS: We created a deterministic model in Microsoft Excel to estimate the costs of contraception provision over a 5-year time horizon (2018 - 2023) from a healthcare provider perspective. Only direct costs of service provision were considered, including drugs, supplies and personnel time. Costs were not discounted owing to the short time horizon. Scenario analyses were conducted to test uncertainty. RESULTS: The base-case cost of current contraceptive use in 2018 was estimated to be ZAR1.64 billion (ZAR29 per capita). Injectable contraceptives accounted for ~47% of total costs. To meet the total demand for family planning, SA would have to spend ~30% more than the estimate for current contraceptive use. In the year 2023, the 'current use' of modern contraceptives would increase to ZAR2.2 billion, and fulfilling the total demand for family planning would require ZAR2.9 billion. The base-case cost of implantable contraceptives was estimated at ZAR54 million. Assuming a normal removal rate, the use of implants is projected to increase by 20% during the 5-year period between 2019 and 2023, with an estimated 46% increase in costs. The cost of early removal of Implanon NXT is estimated at ZAR75 million, with total contraception costs estimated at ZAR102 million in 2019, compared with ZAR56 million when a normal removal rate is applied. CONCLUSIONS: The costs of scaling up modern contraceptives in SA are substantial. Early and premature removals of implantable contraceptives are costly to the nation and must be minimised. The government should consider conducting appropriate health technology assessments to inform the introduction of new public health interventions as SA makes the shift to universal health coverage by means of National Health Insurance.

Healthcare resource use and costs of diabetic macular oedema for patients with antivascular endothelial growth factor versus a dexamethasone intravitreal implant in Korea: a population-based study.

OBJECTIVES: To estimate the costs and healthcare resources of patients with diabetic macular oedema (DME) who received intravitreal antivascular endothelial growth factor (anti-VEGF) agents or a dexamethasone intravitreal implant (DEX-implant) in Korea. DESIGN: Retrospective cohort study. SETTING: The Korean National Health Insurance claim data from 1 January 2015 to 30 June 2017 were retrieved from the Health Insurance Review and Assessment Service. PARTICIPANTS: Adult patients with DME who were diagnosed with diabetic retinopathy or DME and received ranibizumab, aflibercept or a DEX-implant in conjunction with intravitreal injection were included. Patients whose primary diagnoses were age-related macular degeneration or retinal vein occlusion were excluded. MAIN OUTCOME MEASURES: Healthcare resource utilisation and costs related to DME in the 12-month postindex period. RESULTS: During the study period, 182 patients and 414 patients were identified in the anti-VEGF and DEX-implant groups, respectively, and there was no significant difference in the demographic characteristics between the two groups. The outpatient eye care-related medical costs were US$3002.33 for the anti-VEGF group vs US$2250.35 for the DEX-implant group (p<0.0001). After adjusting the relevant covariates based on the generalised linear model, the estimated outpatient eye care-related medical costs were 33% higher in the anti-VEGF group than in the DEX-implant group (p<0.0001, 95% CI 22% to 45%). The utilisation pattern of the two groups showed no significant difference except for the number of intravitreal injections, which was higher in the anti-VEGF group (2.69±2.29) than in the DEX-implant group (2.09±1.37, p<0.001). CONCLUSION: The average annual eye-related medical cost of the DEX-implant group was significantly lower than that of the anti-VEGF group during the study period, which was mainly due to decreased utilisation of eye care-related injections. Further long-term studies are needed.

Dexamethasone implant for non-infectious uveitis: is it cost-effective?

BACKGROUND: Uveitis is inflammation inside the eye. The objective of this study is to assess the cost-effectiveness of a dexamethasone implant plus current practice (immunosuppressants and systemic corticosteroids) compared with current practice alone, in patients with non-infectious intermediate, posterior or pan-uveitis and to identify areas for future research. METHODS: A Markov model was built to estimate the costs and benefits of dexamethasone. Systematic reviews were performed to identify available relevant evidence. Quality of life data from the key randomised-controlled trial (HURON) was used to estimate the interventions' effectiveness compared with the trial's comparator arm (placebo plus limited current practice (LCP)). The analysis took a National Health Service and Personal Social Services perspective. Costs were calculated based on standard UK sources. RESULTS: The incremental cost-effectiveness ratio (ICER) of one dexamethasone implant compared with LCP is estimated as £19 509 per quality-adjusted life year (QALY) gained. The factors with the largest impact on the results were rate of blindness and relative proportion of blindness cases avoided by dexamethasone. Using plausible alternative assumptions, dexamethasone could be cost saving or it may be associated with an ICER of £56 329 per QALY gained compared with LCP. CONCLUSIONS: Dexamethasone is estimated to be cost-effective using generally accepted UK thresholds. However, there is substantial uncertainty around these results due to scarcity of evidence. Future research on the following would help provide more reliable estimates: effectiveness of dexamethasone versus current practice (instead of LCP), with subgroup analyses for unilateral and bilateral uveitis, incidence of long-term blindness and effectiveness of dexamethasone in avoiding blindness.

Budget impact analysis of dexamethasone intravitreal implant for the treatment of diabetic macular oedema.

OBJECTIVE: To assess the economic impact following the inclusion of an intravitreal implant of dexamethasone for the treatment of diabetic macular oedema in a healthcare area in Spain. METHOD: A 3-year budget impact model was designed to estimate healthcare  direct costs for adult patients with diabetic macular oedema from the National  Health System perspective. The approved therapies in use  (aflibercept/ranibizumab/dexamethasone) were considered. The target  population was estimated from published diabetic macular oedema prevalence  (6.41%) and incidence (0.82%) for a population of 25,000 adults.  Dexamethasone was assumed to be used annually in 20%, 30% and 40% of  patients, respectively. Annual total costs included: drug acquisition (based on  frequency of injections per every year, considering exfactory prices with  mandatory deduction and split of vials), intravitreal administration, patient  monitoring, management of cardiovascular and ocular adverse events  (cataracts, increased intraocular pressure, endophthalmitis, vitreous  haemorrhage and retinal detachment). Detailed resource consumption reflecting  clinical practice was provided from local experts in retina and vitreous. Unitary  costs (€, 2016) were obtained from national databases and literature. Sensitivity  analyses were performed to assess model robustness. RESULTS: The inclusion of intravitreal dexamethasone implant would lead to  annual cost savings of €35,030 (-4.2%), €10,743 (-1.8%) and €5,051 (-0.9%), years 1-3 respectively. Total costs were reduced mainly by the fewer annual  injections required by dexamethasone. The average annual incremental costs  were -€350, -€96 and -€41 per patient. CONCLUSIONS: The inclusion of an intravitreal dexamethasone implant for the  treatment of diabetic macular oedema would lead to cost-savings for the  considered health area, mainly by reducing the administration costs.

Objetivo: Determinar el impacto económico tras la inclusión del implante intravítreo de dexametasona para el tratamiento del edema macular diabético en un área sanitaria en España.Método: Se diseñó un modelo de impacto presupuestario a tres años para  estimar los costes directos en pacientes adultos con edema macular diabético,  desde la perspectiva del Sistema Nacional de Salud, considerando terapias  intravítreas actualmente utilizadas (aflibercept/ranibizumab/dexametasona). La  población diana se obtuvo a partir de la prevalencia (6,41%) e incidencia  (0,82%) del edema macular diabético publicadas para una población de 25.000  pacientes adultos. Se asumió un 20%, 30% y 40% anual de pacientes tratados  con dexametasona, respectivamente. El coste total incluyó: coste farmacológico  (precio de venta del laboratorio con deducción obligatoria y fraccionamiento de  viales, según frecuencia de inyecciones necesarias cada año de tratamiento),  administración intravítrea, seguimiento de pacientes y manejo de eventos  oculares (cataratas, hipertensión ocular, endoftalmitis, hemorragia intravítrea y  desprendimiento de retina) y cardiovasculares. El consumo de recursos según la  práctica habitual fue estimado por expertos en retina y vítreo. Los costes  unitarios (€, 2016) se obtuvieron de la literatura y de bases de datos nacionales.  Los análisis de sensibilidad evaluaron la robustez del modelo. Resultados: La inclusión del implante intravítreo de dexametasona supondría reducciones de 35.030 € (­4,2%), 10.743 € (­1,8%) y 5.051 € (­ 0,9%) cada año, respectivamente, disminuyendo principalmente por el menor  número anual de inyecciones requeridas con dexametasona. La reducción anual  promedio supondría 350 €, 96 € y 41 € por paciente.Conclusiones: La inclusión del implante intravítreo de dexametasona para el  tratamiento del edema macular diabético supone ahorros para el área sanitaria  considerada, fundamentalmente por la reducción de costes de administración.

Cost-effectiveness of subdermal implantable buprenorphine versus sublingual buprenorphine to treat opioid use disorder.

AIMS: Subdermal implantable buprenorphine (BSI) was recently approved to treat opioid use disorder (OUD) in clinically-stable adults. In the pivotal clinical trial, BSI was associated with a higher proportion of completely-abstinent patients (85.7% vs 71.9%; p = .03) vs sublingual buprenorphine (SL-BPN). Elsewhere, relapse to illicit drug use is associated with diminished treatment outcomes and increased costs. This study evaluated the cost-effectiveness of BSI vs SL-BPN from a US societal perspective. METHODS: A Markov model simulated BSI and SL-BPN cohorts (clinically-stable adults) transiting through four mutually-exclusive health states for 12 months. Cohorts accumulated direct medical costs from drug acquisition/administration; treatment-diversion/abuse; newly-acquired hepatitis-C; emergency room, hospital, and rehabilitation services; and pediatric poisonings. Non-medical costs of criminality, lost wages/work-productivity, and out-of-pocket expenses were also included. Transition probabilities to a relapsed state were derived from the aforementioned trial. Other transition probabilities, costs, and health-state utilities were derived from observational studies and adjusted for trial characteristics. Outcomes included incremental cost per quality-adjusted-life-year (QALY) gained and incremental net-monetary-benefit (INMB). Uncertainty was assessed by univariate and probabilistic sensitivity analysis (PSA). RESULTS: BSI was associated with lower total costs (-$4,386), more QALYs (+0.031), and favorable INMB at all willingness-to-pay (WTP) thresholds considered. Higher drug acquisition costs for BSI (+$6,492) were outpaced, primarily by reductions in emergency room/hospital utilization (-$8,040) and criminality (-$1,212). BSI was cost-effective in 89% of PSA model replicates, and had a significantly higher NMB at $50,000/QALY ($20,783 vs $15,007; p < .05). CONCLUSIONS: BSI was preferred over SL-BPN from a health-economic perspective for treatment of OUD in clinically-stable adults. These findings should be interpreted carefully, due to some relationships having been modeled from inputs derived from multiple sources, and would benefit from comparison with outcomes from studies that employ administrative claims data or a naturalistic comparative design.

Public Funding for Contraception, Provider Training, and Use of Highly Effective Contraceptives: A Cluster Randomized Trial.

OBJECTIVES: We determined whether public funding for contraception was associated with long-acting reversible contraceptive (LARC) use when providers received training on these methods. METHODS: We evaluated the impact of a clinic training intervention and public funding on LARC use in a cluster randomized trial at 40 randomly assigned clinics across the United States (2011-2013). Twenty intervention clinics received a 4-hour training. Women aged 18 to 25 were enrolled and followed for 1 year (n = 1500: 802 intervention, 698 control). We estimated the effects of the intervention and funding sources on LARC initiation with Cox proportional hazards models with shared frailty. RESULTS: Women at intervention sites had higher LARC initiation than those at control (22 vs 18 per 100 person-years; adjusted hazard ratio [AHR] = 1.43; 95% confidence interval [CI] = 1.04, 1.98). Participants receiving care at clinics with Medicaid family planning expansion programs had almost twice the initiation rate as those at clinics without (25 vs 13 per 100 person-years; AHR = 2.26; 95% CI = 1.59, 3.19). LARC initiation also increased among participants with public (AHR = 1.56; 95% CI = 1.09, 2.22) but not private health insurance. CONCLUSIONS: Public funding and provider training substantially improve LARC access.

Mydriasert pupillary dilation for cataract surgery: an economic and clinical study.

BACKGROUND: Mydriasert is an insoluble ophthalmic insert indicated for mydriasis prior to cataract surgery, which gradually releases the active ingredients: tropicamide (0.25 mg) and phenylephrine (5.38 mg). This study aimed to evaluate the cost of Mydriasert compared with conventional mydriatic eye drops to induce pupil dilation prior to cataract surgery using a budget impact model. METHODS: A cohort-based, decision tree, budget impact model was developed to estimate the drug, consumable and staff costs for achieving mydriasis with Mydriasert compared to mydriatic eye drops (tropicamide [1%] plus phenylephrine [10%]). Insights from structured interviews with clinicians (n = 5) experienced in using both Mydriasert and mydriatic eye drops and results from the current clinical study of patients undergoing cataract surgery (n = 144) at a Greater London district general hospital were used to obtain key input parameters for the model, and to validate the model approach. RESULTS: The base case analysis in a cohort of 1763 patients undergoing cataract surgery showed that when Mydriasert substituted mydriatic eye drops, annual total costs decreased by 18% and annual total nurse time decreased from 235.1 hours to 44.1 hours over one year (2012-2013). CONCLUSIONS: This study demonstrated that despite its higher unit cost than mydriatic eye drops, Mydriasert resulted in overall savings in health-care costs, mainly associated with reduced nursing time. The economic model developed could assist National Health Service managers and local payers to estimate the budget impact of the introduction of Mydriasert into different clinical settings.

Increasing LARC utilization: any woman, any place, any time.

Intrauterine contraceptive devices and the progestin implant are the most effective long-acting reversible contraception (LARC) methods available for preventing unintended pregnancy. LARC devices are safe, non-user-dependent methods that have the highest rates of continuation and satisfaction of all reversible contraceptives. Use of these contraceptives remains low in the United States due to several barriers including: misperceptions among both providers and patients; cost barriers; and patient access to the devices. Increasing the opportunities for women to access LARC methods in the primary care, postabortion, and postpartum setting can be achieved by addressing the system, provider, and patient barriers that exist.

Changes in hospital and out-patient events and costs following implant naltrexone treatment for problematic alcohol use.

The harmful use of alcohol places a considerable burden on the community, both socially and financially. The aim of this study was to determine if the use of implant naltrexone is associated with a reduction in health care events and costs in patients treated for problematic alcohol use. Ninety four patients (60.6% male) treated between 2002 and 2007 were matched against state hospital, emergency department (ED), mental health out-patients and mortality data sets for 6 months prior to and 6 months post treatment. The number of patients, events, and costs associated with each health event were compared before and after treatment. Overall health care events and costs were reduced from $509033 prior to treatment to $270001 following treatment. Costs associated with hospital admission showed the most significant reduction, falling from $424605 (82 admissions/36 patients) before treatment to $203462 (43 admission/24 patients) after. While costs associated with ED attendances also fell ($74885 to $54712), costs associated with mental health out-patient attendances increased ($9543 to $11827). The use of implant naltrexone was associated with a reduction health events and costs in patients with problematic alcohol use in the first 6 months following treatment.

Game change in Colorado: widespread use of long-acting reversible contraceptives and rapid decline in births among young, low-income women.

CONTEXT: Long-acting reversible contraceptive (LARC) methods are recommended for young women, but access is limited by cost and lack of knowledge among providers and consumers. The Colorado Family Planning Initiative (CFPI) sought to address these barriers by training providers, financing LARC method provision at Title X-funded clinics and increasing patient caseload. METHODS: Beginning in 2009, 28 Title X-funded agencies in Colorado received private funding to support CFPI. Caseloads and clients' LARC use were assessed over the following two years. Fertility rates among low-income women aged 15-24 were compared with expected trends. Abortion rates and births among high-risk women were tracked, and the numbers of infants receiving services through the Special Supplemental Nutrition Program for Women, Infants and Children (WIC) were examined. RESULTS: By 2011, caseloads had increased by 23%, and LARC use among 15-24-year-olds had grown from 5% to 19%. Cumulatively, one in 15 young, low-income women had received a LARC method, up from one in 170 in 2008. Compared with expected fertility rates in 2011, observed rates were 29% lower among low-income 15-19-year-olds and 14% lower among similar 20-24-year-olds. In CFPI counties, the proportion of births that were high-risk declined by 24% between 2009 and 2011; abortion rates fell 34% and 18%, respectively, among women aged 15-19 and 20-24. Statewide, infant enrollment in WIC declined 23% between 2010 and 2013. CONCLUSIONS: Programs that increase LARC use among young, low-income women may contribute to declines in fertility rates, abortion rates and births among high-risk women.

Surgical and anesthetic considerations in histrelin capsule implantation for the treatment of precocious puberty.

BACKGROUND: Precocious puberty treatment traditionally meant anxiety-provoking monthly depot injections until the advent of the annually implanted histrelin capsule. This study is the first to evaluate the surgical and anesthetic aspects of histrelin implantation for precocious puberty. METHODS: All cases from one surgeon at a tertiary pediatric hospital were reviewed for patient age, anesthetic type, technical difficulties, and complications. RESULTS: From 12/2007 to 3/2013, 114 cases (49% implantations, 25% removals/re-implantations, 25% removals) were performed. Local anesthesia was employed in 100% of non-general anesthesia cases (n=109, 96%), augmented by inhaled N2O in 49%. Five patients (4%) underwent general anesthesia: three neurologically-impaired and two coordinated with scheduled MRIs. Procedural difficulties (n=18, 16%) included implant fracture during removal (n=16/58 removals, 28%). Fracture never occurred during implantation. Three children (3%) suffered complications. One infection was treated with antibiotics, and two implants were removed for systemic allergic reaction. Six children (5%) had unscheduled post-operative checks for pain (n=3, 3%), allergy to elastic dressing (n=2, 2%), or rash (n=1, 1%). Mean charges for general anesthesia were $10,188±1292 versus $528±147 for N2O or local alone (p<0.0001). CONCLUSION: While histrelin implantation is straightforward, removal presents technical challenges. Local anesthesia, with possible N2O supplementation, is well-tolerated and introduces substantial resource and cost savings.

Budget impact analysis of 8 hormonal contraceptive options.

OBJECTIVES: To develop a model comparing costs of 8 hormonal contraceptives and determine whether acquisition costs for implants and intrauterine devices (IUDs) were offset by decreased pregnancy-related costs over a 3-year time horizon from a managed care perspective. STUDY DESIGN: A model was developed to assess the budget impact of branded or generic oral contraceptives (OCs), quarterly intramuscular depot medroxyprogesterone, etonogestrel/ethinyl estradiol vaginal ring, etonogestrel implant, levonorgestrel IUD, norelgestromin/ethinyl estradiol transdermal contraceptive, and ethinyl estradiol/levonorgestrel extended-cycle OC. METHODS: Major variables included drug costs, typical use failure rates, discontinuation rates, and pregnancy costs. The base case assessed costs for 1000 women initiating each of the hormonal contraceptives. RESULTS: The etonogestrel implant and levonorgestrel IUD resulted in the fewest pregnancies, 63 and 85, respectively, and the least cost, $1.75 million and $2.0 million, respectively. In comparison, generic OC users accounted for a total of 243 pregnancies and $3.4 million in costs. At the end of year 1, costs for the etonogestrel implant ($800,471) and levonorgestrel IUD ($949,721) were already lower than those for generic OCs ($1,146,890). Sensitivity analysis showed that the cost of pregnancies, not product acquisition cost, was the primary cost driver. CONCLUSIONS: Higher initial acquisition costs for the etonogestrel implant and levonorgestrel IUD were offset within 1 year by lower contraceptive failure rates and consequent pregnancy costs. Thus, after accounting for typical use failure rates of contraceptive products, the etonogestrel implant and levonorgestrel IUD emerged as the least expensive hormonal contraceptives.

Medical cost impact of intrathecal drug delivery for noncancer pain.

INTRODUCTION: As healthcare budgets continue to contract, there is increased payer scrutiny on the use of implantable intrathecal drug-infusion devices. This study utilizes claims data to evaluate the economic effects of intrathecal drug delivery (IDD) based on health services utilization and costs of care before and after implantation. METHODS: We performed a retrospective database study involving 555 noncancer pain patients that received an IDD system implant within a 3-year service period (1/2006-1/2009). IDD patient costs were temporally aligned to implant month and repriced to a standardized, national pricing schedule over a 6-year episode cycle (3 years preimplant, implant month, and 3 years postimplant). Additionally, we made an actuarial projection of postimplant experience, in the absence of IDD intervention, simulating a conventional pain therapy (CPT) protocol by assuming the same slope in costs prior to implantation at standardized, national price levels. Cost projections were produced over a 30-year time horizon at various reimplantation rates. RESULTS: IDD therapy was less costly than the CPT protocol over our baseline implantation cycle. Costs in the month of IDD implantation, and in the year following, are cumulatively $17,317 more than the CPT protocol; however, IDD financial break-even occurs soon after the second year postimplant. The lifetime analysis indicates that IDD per patient per year savings is $3,111 compared with CPT. CONCLUSION: The authors found that patients receiving an implantable IDD system may experience reduced cumulative future medical costs relative to anticipated costs in the absence of receiving IDD. This finding complements published literature on the cost-effectiveness of IDD.

Dedicated providers of long-acting reversible contraception: new approach in Zambia.

BACKGROUND: Long-acting reversible contraception (LARC) is underused in many countries in sub-Saharan Africa. Many previous attempts to increase uptake of this important class of contraception have not been successful. STUDY DESIGN: This program in Zambia employed 18 dedicated providers of LARC, placed them in high volume public sector facilities and collected routine, anonymous information over a 14-month period. We tallied uptake of LARC, analyzed user characteristics to see what populations were reached by the program and compared this to nationally representative data. We also estimated costs per couple-year of protection of the program. RESULTS: In a 14-month period, 33,609 clients chose either a subdermal implant (66%) or an intrauterine device (34%). The program reached a younger and lower parity population compared to nationally representative surveys of Zambian women using contraception. The estimated program costs, including the value of donated commodities, averaged $13.0 per couple-year of protection. CONCLUSION: By having the necessary time, skills and materials - as well as a mandate to both generate informed demand and provide quality services - dedicated providers of LARC can expand contraceptive choice. This new approach shows what can be achieved in a short period and in a region of the world where uptake of LARC is limited.

Steer responses to feeding soybean hulls and steroid hormone implantation on toxic tall fescue pasture.

Crossbred steers were grazed in the spring and early summer on endophyte-infected (Neotyphodium coenophialum), Kentucky-31 tall fescue (Lolium arundinaceum) pastures to evaluate effects and interactions of feeding pelleted soybean hulls (PSBH) and steroid hormone implants (SHI) on steer performance, serum prolactin, and hair coat ratings (HCR). Steers were stratified by BW for assignment to six 3.0-ha toxic tall fescue pastures. With or without daily PSBH feeding, treatments were assigned randomly to pastures as the main plot treatment in a split-plot design. Pelleted soybean hulls were group-fed to provide 2.3 kg(steer·d(-1)) (as fed). With or without SHI (200 mg of progesterone and 20 mg of estradiol) treatments were randomly assigned as the subplot treatment to 2 steer subgroups within each pasture. Sixty-four steers were grazed for 77 d in 2007, and 60 steers were grazed for 86 d in 2008. Pasture forage mass declined linearly over time, but the rate of decline was greater (P = 0.001) in 2007 than in 2008. Pasture forage mass was never below 2,300 kg of DM/ha in either year. Average daily gain for steers on the combined PSBH and SHI treatments was greater (P < 0.01) than for those on the PSBH-only, SHI-only, and control (no SHI, no PSBH) treatments. Average daily gain for the PSBH-only steers was greater (P < 0.01) than for SHI-only and control steers and tended (P = 0.063) to be greater for SHI-only than for control steers. Steroid implants did not affect (P = 0.826) serum prolactin concentrations; however, prolactin concentrations in PSBH steers, with or without SHI, were increased (P = 0.01) 2-fold over SHI-only and control steers. Feeding PSBH and SHI treatments both reduced (P < 0.05) the percentage of steers with rough HCR, and a greater percentage of steers fed PSBH tended (P < 0.076) to have sleek hair coats. An economic analysis was conducted, which determined that costs of additional ADG with PSBH feeding were below breakeven costs over a wide range of PSBH costs and cattle prices. Breakeven costs for PSBH-only treatment for a range of cattle prices of $1.80 to $2.40/kg of BW were less than $120/t, whereas with PSBH feeding combined with SHI the breakeven cost was less than $240/t. Results indicate that steers grazing endophyte-infected tall fescue can be fed PSBH and implanted with steroid hormones to cost effectively increase ADG and that feeding PSBH can increase serum prolactin concentrations and induce some shedding of rough hair coats.

The Contraceptive CHOICE Project: reducing barriers to long-acting reversible contraception.

OBJECTIVE: To introduce and promote the use of long-acting reversible methods of contraception (LARC; intrauterine contraceptives and subdermal implant) by removing financial and knowledge barriers. STUDY DESIGN: The Contraceptive CHOICE Project is a prospective cohort study of 10,000 women 14-45 years who want to avoid pregnancy for at least 1 year and are initiating a new form of reversible contraception. Women screened for this study are read a script regarding long-acting reversible methods of contraception to increase awareness of these options. Participants choose their contraceptive method that is provided at no cost. We report the contraceptive choice and baseline characteristics of the first 2500 women enrolled August 2007 through December 2008. RESULTS: Sixty-seven percent of women enrolled (95% confidence interval, 65.3-69.0) chose long-acting methods. Fifty-six percent selected intrauterine contraception and 11% selected the subdermal implant. CONCLUSION: Once financial barriers were removed and long-acting reversible methods of contraception were introduced to all potential participants as a first-line contraceptive option, two-thirds chose long-acting reversible methods of contraception.
