Interconception Care for Mothers at Well Child Visits After Implementation of the IMPLICIT Model.

INTRODUCTION: Interconception care (ICC) is recommended to reduce maternal risk factors for poor birth outcomes between pregnancies. The IMPLICIT ICC model includes screening and brief intervention for mothers at well child visits (WCVs) for smoking, depression, multivitamin use, and family planning. Prior studies demonstrate feasibility and acceptability among providers and mothers, but not whether mothers recall receipt of targeted messages. METHODS: Mothers accompanying their child at 12- and 24-month WCVs at four sites of a family medicine academic practice were surveyed pre (2012) and post (2018) ICC model implementation. Survey items assessed health history, behaviors, and report of whether their child's physician addressed maternal depression, tobacco use, family planning, and folic acid supplementation during WCVs. Pre and post results are compared using logistic regression adjusting for demographics and insurance. RESULTS: Our sample included 307 distinct mothers with 108 and 199 respondents in the pre and post periods, respectively. Mothers were more likely to report discussions with their child's doctor post-intervention for family planning (31% pre to 86% post; aOR 18.65), depression screening (63-85%; aOR 5.22), and taking a folic acid supplement (53-68%; aOR 2.54). Among mothers who smoked, the percentage that reported their child's doctor recommended cessation increased from 56 to 75% (aOR = 3.66). DISCUSSION: The IMPLICIT ICC model resulted in increased reported health care provider discussions of four key areas of interconception health by mothers attending WCVs. This model holds promise as a primary care strategy to systematically address maternal risks associated with poor pregnancy outcomes.

Adherence in dermatology.

Non-adherence to treatment and medical recommendations is one of the leading causes of treatment failure, poor clinical outcomes, and increased healthcare utilization. Although non-adherence is observed across all medical specialties, adherence to treatment in dermatology deserves special attention given the multiple different routes of treatment. Adherence can be measured using subjective methods (patient reporting and questionnaires) or objective methods (pill counts, electronic chips, and pharmacy records). Adherence to dermatologic treatments varies based on the specific condition but is poor for systemic therapies and even worse with topical agents. Among the factors that influence adherence, duration of treatment, complexity of regimen, and access play a large role. Interventions to improve adherence can range from simplifying treatment regimens to scheduling more frequent office visits. Due to the profound effect on cost, healthcare outcomes, and mortality, understanding and improving adherence is equally as important as making the correct diagnosis and prescribing the correct treatment.

Trends in systemic psoriasis treatment therapies from 1993 through 2010.

BACKGROUND: Moderate-to-severe psoriasis generally requires systemic therapy, and is often undertreated. OBJECTIVE: To determine and analyze what courses of treatment and in what frequency are being utilized to combat psoriasis in the United States. METHODS: Analysis of data from the National Ambulatory Medical Care Survey (NAMCS) and National Hospital Ambulatory Medical Care Survey (NHAMCS) of the National Center for Health Statistics. Data were analyzed to examine the prevalence of different therapy techniques to combat psoriasis from 1993 through 2010. The trends for phototherapy, methotrexate (MTX), retinoids, cyclosporine A (CSA), systemic steroids, and biologics were all analyzed over the entire 18-year period and independently before and after the introduction of biologics in 2002. RESULTS: From 1993 to 2010, the trend for total systemic treatments has not significantly increased (P=0.5). Frequency of phototherapy treatments significantly decreased from 1993 to 2010 (P<0.001). Since the introduction of biologics in 2002, their frequency has significantly increased, becoming the most frequently used treatment from 2008-2010 (P<0.0001). LIMITATIONS: Severity of psoriasis was not recorded in the NAMCS and NHAMCS. CONCLUSIONS: The frequency of systemic treatments to treat psoriasis has not significantly increased from 1993 to 2010. Despite the introduction of biologics, it appears that little progress has been made in reducing under-treatment of moderate-to-severe psoriasis.

Use of St. John's Wort in potentially dangerous combinations.

OBJECTIVES: The objective of this study was to assess how often St. John's wort (SJW) is prescribed with medications that may interact dangerously with it. DESIGN: The study design was a retrospective analysis of nationally representative data from the National Ambulatory Medical Care Survey. SETTINGS: The study setting was U.S. nonfederal outpatient physician offices. SUBJECTS: Those prescribed SJW between 1993 and 2010 were the subjects. OUTCOME MEASURES: The outcome measures were medications co-prescribed with SJW. RESULTS: Twenty-eight percent (28%) of SJW visits involved a drug that has potentially dangerous interaction with SJW. These included selective serotonin reuptake inhibitors, benzodiazepines, warfarin, statins, verapamil, digoxin, and oral contraceptives. CONCLUSIONS: SJW is frequently used in potentially dangerous combinations. Physicians should be aware of these common interactions and warn patients appropriately.

Complementary and alternative medicine use in dermatology in the United States.

BACKGROUND: Complementary and alternative medicine (CAM) has an increasing presence in dermatology. Complementary therapies have been studied in many skin diseases, including atopic dermatitis and psoriasis. OBJECTIVES: This study sought to assess oral CAM use in dermatology relative to medicine as a whole in the United States, using the National Ambulatory Medical Care Survey. DESIGN: Variables studied include patient demographic characteristics, diagnoses, and CAM documented at the visits. A brief literature review of the top 5 CAM treatments unique to dermatology visits was performed. RESULTS: Most CAM users in both dermatology and medicine as a whole were female and white and were insured with private insurance or Medicare. Fish oil, glucosamine, glucosamine chondroitin, and omega-3 were the most common complementary supplements used in both samples. CONCLUSIONS: CAM use in dermatology appears to be part of a larger trend in medicine. Knowledge of common complementary therapies can help dermatologists navigate this expanding field.

Phototherapy trends in dermatology.

BACKGROUND: Use of phototherapy in the United States declined during the 1990s, largely due to unfavorable economic incentives. The trends in phototherapy since then are not well characterized. METHODS: We analyzed the National Ambulatory Medical Care Survey (NAMCS) data on quantity of phototherapy visits and associated diagnoses and payment sources. Trends were assessed by linear regression. RESULTS: There were an estimated 230 000 outpatient phototherapy visits per year, with an increasing trend over time (p = 0.03). Dermatologists managed 87% of the visits. Leading diagnoses associated with phototherapy included psoriasis (25%), dermatitis NOS (6%), vitiligo (6%), other dyschromia (6%), and actinic keratosis (5%). CONCLUSIONS: Use of phototherapy for psoriasis has remained relatively low up to 2010. However, phototherapy may be becoming more frequent for conditions other than psoriasis.

Acitretin prescribing patterns in women of childbearing potential.

BACKGROUND: Acitretin is indicated for severe psoriasis, but it is also a potent teratogen whose use should be avoided in women of childbearing potential. Topical medications, phototherapy, cyclosporine A, and new biologic agents provide safer alternatives for women of childbearing age with moderate to severe psoriasis. PURPOSE: To determine the demographics of acitretin prescribing patterns as an assessment of acitretin use in women of child-bearing potential. METHODS: We examined National Ambulatory Medical Care Survey (NAMCS) data from the years 1990-2009 to determine demographic data on patients who were prescribed etretinate or acitretin. We used age under 50 as a proxy for childbearing potential. RESULTS: From 1996-2009, there were an estimated 29 million office visits for psoriasis. Females accounted for 14.3 million of these visits, and 6.5 million (45.6%) of them were under the age of 50. The NAMCS contained only one record of a female patient under the age of 50 being prescribed acitretin from 1996-2009, the years during which acitretin had been available in the United States. This corresponds to an estimated 2.3% of all psoriasis patients prescribed acitretin during this time (20,000 out of 890,000). LIMITATIONS: The NAMCS estimates national trends based on a large nationwide database. While the use of acitretin in women under 50 is low, the precision of the estimate is limited by the small sample size provided by this database. CONCLUSIONS: There are now many alternative treatments besides acitretin for women of childbearing potential with moderate to severe psoriasis. Acitretin is used at most infrequently in this population. In females of reproductive potential, acitretin should be reserved for non-pregnant patients who are unresponsive to other therapies or whose clinical condition contraindicates the use of other treatments.

Cost effectiveness of biologic therapies for plaque psoriasis.

BACKGROUND: During the last decade, the implementation of biologic agents has changed the therapeutic management of severe psoriasis. Biologic agents have clinically proven efficacy, but their use is associated with a much higher cost compared with traditional treatment options. Therefore, when assessing the use of these drugs for the treatment of psoriasis, it is important to consider their cost effectiveness. OBJECTIVE: The objective of this study was to determine and compare the cost effectiveness of biologic agents with regard to the cost per patient achieving a minimally important difference (MID) in the Dermatology Life Quality Index (DLQI) and the cost per patient achieving a 75% improvement in the Psoriasis Area Severity Index (PASI-75). METHODS: A PubMed literature search was conducted to identify studies describing the efficacy of all currently US FDA-approved biologic therapies. The cost effectiveness of each agent over a 12-week period was determined and a sensitivity analysis was performed. Based on clinical efficacy at 12 weeks, treatment paradigms were extrapolated to estimate cost-effectiveness ratios after 1 year of treatment. Pooled data on each biologic agent at different doses were compared in a one-way sensitivity analysis and in an extreme case scenario analysis. RESULTS: Twenty-seven studies were included in the analysis. Intravenous (IV) infliximab 3 mg/kg was the most cost-effective biologic agent with respect to both the cost per patient achieving PASI-75 and the cost per patient achieving a DLQI MID. The next most cost-effective agents in terms of cost per patient achieving PASI-75 were subcutaneous (SQ) adalimumab 40 mg administered every other week (eow) after an 80-mg loading dose, SQ adalimumab 40 mg eow, and IV infliximab 5 mg/kg. In terms of cost per patient achieving DLQI MID, IV infliximab 5 mg/kg, SQ etanercept 25 mg once weekly, SQ etanercept 50 mg once weekly, and SQ adalimumab 50 mg eow after an 80-mg loading dose were the next most cost-effective agents behind IV infliximab 3 mg/kg. For both costs per patient achieving DLQI MID and PASI-75, alefacept was the least cost-effective agent up to a 10% level of variation at all doses except 0.025 mg/kg once weekly. LIMITATIONS: This study was limited by the use of efficacy data from 12-week clinical trials that did not compare treatments head to head to determine relative efficacy and may not be generalizable to longer treatment periods. Additionally, the estimated cost of treatment did not take into account indirect costs or variations in costs due to insurance company price contracting. CONCLUSIONS: Biologic treatments that were most cost effective were so in respect to both the cost per patient achieving DLQI MID and per patient achieving PASI-75. This suggests that the same agents that are effectively clearing the disease are also effective in improving the patients' subjective assessment of dermatology-related quality of life.

The effect of folate supplementation on methotrexate efficacy and toxicity in psoriasis patients and folic acid use by dermatologists in the USA.

BACKGROUND: Methotrexate (MTX) is an effective treatment for psoriasis but its use is limited by its toxicity. Folate supplementation can be used to reduce the adverse effects of MTX, though this may impact efficacy. The frequency of folic acid supplementation is not well characterized. PURPOSE: The objective of this study was to review the literature involving the use of folate in patients (in particular those with psoriasis) treated with MTX and analyze trends in folic acid use. METHODS: We searched PubMed from 1 May 1989 through 1 April 2012 using the terms 'folic acid,' 'folinic acid,' 'folate,' 'supplementation,' and 'methotrexate.' We also used the National Ambulatory Medical Care Survey (NAMCS) database to collect data regarding trends in MTX use and folic acid supplementation by physicians in the USA from 1993 through 2009. We assessed data including the number of MTX visits, rate of folic acid use, diagnoses, physician specialty, and demographics of patients. We used linear regression to analyze the change in folic acid use over time. RESULTS: Twenty-six published trials were included addressing folic acid supplementation with MTX. The majority found a benefit to folic acid supplementation, but there were only seven studies in psoriasis. Dermatologists were among the highest prescribers of MTX, and psoriasis was commonly treated with MTX. Folic acid supplementation significantly increased over this time period (p < 0.0001). However, dermatologists ranked lowest for their folate use, co-prescribing folate to only 9.1 % of MTX-treated patients. LIMITATIONS: In contrast to rheumatoid arthritis, there is a scarcity of literature describing the effect of folate on MTX toxicity and efficacy in psoriasis patients. NAMCS data only included outpatient visits to non-federally employed physicians, and there is the possibility of healthcare providers not documenting over-the-counter folic acid usage. Lastly, doses of MTX and folic acid were not recorded in the database. CONCLUSION: Dermatologists were the least likely specialists to supplement MTX with folic acid. The evidence for supplementation of folic acid is mixed. The literature confirms a reduction in the adverse effects of MTX but less strongly that there may be a reduction in efficacy too. Keeping in mind the potential for folate to reduce MTX efficacy, folic acid supplementation should be considered in MTX-treated patients.
