Patient Medication Adherence Among Pharmacies Participating in a North Carolina Enhanced Services Network.

BACKGROUND: Improving medication adherence can reduce health care spending, and studies have demonstrated community pharmacists can positively affect adherence through the provision of enhanced services. The North Carolina (NC) Community Pharmacy Enhanced Services Network (CPESN) was formed in early 2014 with the goal of enhancing the care provided through its network pharmacies. OBJECTIVE: To evaluate differences in medication adherence performance scores between pharmacies that participated in the NC-CPESN and control pharmacies in NC that did not. METHODS: Medication adherence performance data for statins, renin-angiotensin system antagonists, oral diabetes medications, and a custom multiple chronic medication measure were gathered from quarterly reports between December 2014 and September 2016. Data for these quarterly reports were derived from NC Medicaid claims. These data were combined with pharmacy demographics and service offerings data from the National Council on Prescription Drug Plans dataQ database. Descriptive statistics were used to evaluate differences in demographics and service offerings between study cohorts. Generalized estimating equations were used to evaluate the relationship between medication adherence and pharmacy cohorts, demographics, and service offerings. RESULTS: There were 267 enhanced services pharmacies and 1,872 control pharmacies included in this analysis. Enhanced services pharmacies were much more likely to be independent pharmacies, located in rural counties, offer multidose compliance packaging, and offer delivery services, but were less likely to offer 24-hour emergency services. Persistently higher adherences scores were observed for enhanced services pharmacies, with differences across measures ranging from 3.0% to 7.2% (P < 0.001). In multivariable models, the difference between enhanced services and control pharmacies was explained by differences in offerings of multidose compliance packaging and delivery services, which were associated with 3.4%-8.2% and 3.3%-4.0% improvements in adherence, respectively (P < 0.001). CONCLUSIONS: This study found that enhanced services pharmacies had greater adherence performance scores for the NC Medicaid population. These differences appear to be due to CPESN enhanced services pharmacies' offering of multidose compliance packaging and delivery. Future work is needed to expand this analysis to other populations, as well as to explore the relationship between delivery and adherence.

A Systematic Review of the Effect of Cancer Treatment on Work Productivity of Patients and Caregivers.

BACKGROUND: Cancer is a leading cause of death with substantial financial costs. While significant data exist on the economic burden of care, less is known about the indirect costs of treatment and, specifically, the effect on work productivity of patients and their caregivers. To examine the full effect of cancer and the potential value of new therapies, all aspects of care, including indirect costs and patient-reported outcomes, should be evaluated. OBJECTIVE: To perform a systematic review of the literature examining the effect of cancer treatment on work productivity in patients and their caregivers. METHODS: Articles, abstracts, and bibliographies were searched in MEDLINE, Cochrane, Scopus, CINAHL, and conference lists from the American Society of Clinical Oncology, International Society for Pharmacoeconomics and Outcomes Research, and Academy of Managed Care Pharmacy up to January 2016. The PRISMA guidelines were used. Controlled search terminology included individual pharmacologic therapies for cancer and terms related to patient and caregiver work productivity. Citations were included if they evaluated the effect of cancer treatment on work productivity, used and described productivity assessments and instruments, and were written in English. Studies that reported only clinical outcomes or assessed only nonpharmacological treatments were excluded. Identified studies were screened and extracted for study inclusion by 2 independent reviewers, with adjudication by 2 secondary reviewers during the final eligibility phase. RESULTS: Of 978 potential citations, 62 articles or abstracts were included. Forty-six studies (74.2%) evaluated patient-related productivity; 10 studies (16.1%) focused on caregivers, and 6 studies (9.7%) were a combination. Sixteen countries contributed literature, including 26 studies (41.2%) conducted in the United States. The most commonly studied cancer was breast cancer (53.2%). Nearly 22% of the studies were conducted on multiple types of cancer. The significant diversity of study methodologies and measurements rendered a single unifying conclusion difficult. A variety of metrics were used to quantify productivity (hours lost, return to work, change of status, and activity impairment). The Work Productivity and Activity Impairment questionnaire was the most commonly used standardized tool (n = 9; 14.5%). Factors found to be associated with impairment in productivity included disease- and treatment-related effects, such as disease progression and severity, cognitive and neurological impairments, poor physical and psychological status, receipt of chemotherapy, and time and expenses required to receive therapy. CONCLUSIONS: This review highlights the considerable variety of studies that have assessed work productivity for cancer treatment and the multifaceted reasons affecting patients and caregivers. With increasing emphasis being given to understanding the value that patients assign to various aspects of cancer treatment, more streamlined information on productivity may be important to patients as they play a greater role in selecting treatment goals through shared decision making with their providers.

Exenatide BID and liraglutide QD treatment patterns among type 2 diabetes patients in Germany.

OBJECTIVES: This study evaluated patient and prescriber characteristics, treatment patterns, average daily dose (ADD), and glycemic control of patients initiating glucagon-like peptide 1 (GLP-1) receptor agonists in Germany. METHODS: The LifeLink™ EMR-EU database was searched to identify patients initiating exenatide twice daily (BID) or liraglutide once daily (QD) during the index period (January 1, 2009-April 4, 2010). Eligible patients had ≥ 180 days pre-index history, ≥ 90 days post-index follow-up, and a pre-index type 2 diabetes diagnosis. Univariate tests were conducted at α=0.05. RESULTS: Six hundred and ninety-two patients were included (exenatide BID 292, liraglutide QD 400): mean (SD) age 59 (10) years, 59% male. Diabetologists prescribed liraglutide QD to a larger share of patients (65% vs 35% exenatide BID) than non-diabetologists (51% vs 49%). GLP-1 receptor agonist choice was not associated with age (p=0.282), gender (p=0.960), number of pre-index glucose-lowering medications (2.0 [0.9], p=0.159), pre-index HbA1c (8.2 [1.5%], p=0.231) or Charlson Comorbidity Index score (0.45 [0.78], p=0.547). Mean (SD) ADD was 16.7 mcg (9.2, label range 10-20 mcg) for exenatide BID and 1.4 mg (0.7, label range 0.6-1.8 mg) for liraglutide QD. Among patients with post-index HbA1c tests, mean unadjusted values did not differ between cohorts. Exenatide BID patients were more likely than liraglutide QD patients to continue pre-index glucose-lowering medications (67.1% vs 60.3%, p=0.027) or to start concomitant glucose-lowering medications at index (32.2% vs 25.0%, p=0.013); exenatide BID patients were less likely to augment treatment with another drug post-index (15.8% vs 22.5%, p=0.027). LIMITATIONS: Results may not be generalizable. Lab measures for clinical outcomes were available only for a sub-set of patients. CONCLUSIONS: Results suggested that some differences exist between patients initiating exenatide BID or liraglutide QD, with respect to prescribing physician specialty and pre- and post-index treatment patterns. Both GLP-1 receptor agonists showed comparable post-index HbA1c values in a sub-set of patients.

Patterns of treatment with chemotherapy and monoclonal antibodies for metastatic colorectal cancer in Western Europe.

BACKGROUND AND OBJECTIVES: Treatment outcomes improved in metastatic colorectal cancer (mCRC) due to the introduction of new chemotherapies and monoclonal antibodies. This study describes current patterns of pharmacological treatment for mCRC in clinical practice in four European countries. METHODS: This cohort study used physician-survey data from the LifeLink Oncology Analyzer Database for mCRC patients in France, Germany, Italy and Spain. All patients aged ≥21 years at mCRC diagnosis and with data collected during 2009 were included. Treatment patterns were examined descriptively by lines of therapy. RESULTS: The study sample included 2682 mCRC patients. In first-line, more patients received FOLFOX (infusional 5-fluorouracil/leucovorin and oxaliplatin)- than FOLFIRI (infusional 5-fluorouracil/leucovorin and irinotecan)-, containing regimens in Germany (42 vs. 30%) and Spain (25 vs. 16%), while in Italy and France the reverse was true (Italy: 34% FOLFIRI vs.29% FOLFOX; France: 26 vs. 19%). In second-line, FOLFIRI-containing regimens were more commonly used than FOLFOX-containing regimens in Germany (36 vs. 18%), Italy (29 vs. 14%), and Spain (34 vs. 6%), while similar proportions of FOLFOX and FOLFIRI were used in France (18 vs. 15%). As part of first-line treatment, bevacizumab use ranged from 44% of patients in Italy to 30% in Spain, with slightly lower rates in second-line. Cetuximab first-line use ranged from 14% of patients in Spain to 7% in Italy, increasing in second-line to 30% in Spain, 26% in Italy, 20% in Germany, and 17% in France. LIMITATIONS: This analysis focused on description of treatment patterns, however, the actual clinical benefits of these treatment regimens on survival or quality of life were not addressed due to lack of relevant information in the data source. Some country differences in treatment patterns were observed. These differences might be partly explained by differences in local treatment guidelines, physician prescribing behaviours, reimbursement policies, and response to various regimens due to genetic differences. CONCLUSIONS: In clinical practice in four European countries, FOLFOX- and FOLFIRI-based regimens are common standard of care chemotherapies for mCRC (FOLFOX and bevacizumab + FOLFIRI are the most common regimens), and monoclonal antibodies are often combined with these chemotherapies.

Major surgery in patients with metastatic colorectal cancer in Western europe.

PURPOSE: Given the potential interference between treatment for metastatic colorectal cancer (mCRC) and surgical procedures, we sought to determine the prevalence of major surgery following mCRC diagnosis in clinical practice. METHODS: This cohort study used physician-surveyed data from the LifeLink™ Oncology Analyzer database for mCRC patients in five European countries (France, Germany, Italy, Spain, and the United Kingdom [UK]). All patients aged ≥21 years at mCRC diagnosis and with data collected during 2009 were included. Major surgical procedures were examined descriptively by the purpose and location of surgery. RESULTS: The study sample included 3,249 mCRC patients; 515, 862, 656, 649, and 567 were from France, Germany, Italy, Spain, and the UK, respectively. Following mCRC diagnosis, at least one major surgical procedure for any purpose was seen in 30.5% (UK), 35.2% (Germany), 35.6% (Spain), 36.3% (France), and 38.4% (Italy) of patients, with a mean of 1.3 (UK) to 1.6 (France) procedures. The rate of major surgery for curative purposes was the highest in Italy (13.4%), followed by France (12.8%), Spain (10.3%), and Germany (9.2%); the lowest was in the UK (7.2%). Major surgery performed on the primary tumor (12.4-27.1% of patients, depending on the country) and metastasis (6.4-14.6%) made up the majority of all surgical procedures. CONCLUSIONS: Major surgery is highly prevalent following mCRC diagnosis, suggesting an important role in meeting the goals of mCRC treatment. The role of pharmacological treatment options and their potential to interfere with both surgery use and surgical outcomes should be considered when evaluating mCRC treatment strategies.

Health care costs associated with treatment modification in type 2 diabetes mellitus patients taking oral anti-diabetic drugs.

OBJECTIVES: To compare health care costs among patients with type 2 diabetes mellitus (T2DM) who added a new oral anti-diabetes drug (OAD) to an initial regimen with those who up-titrated their initial OAD. METHODS: Insurance claims data were obtained from 94 health plans for patients aged ≥18 years with ICD-9-CM diagnosis of T2DM during the period Jan. 1, 2001-June 30, 2007, and a newly prescribed metformin or sulfonylurea monotherapy. Patients were followed after initiating monotherapy to identify occurrence of first-treatment modification (addition or up-titration). Health care costs were analyzed during 360 days after first treatment modification. Subgroup analyses included comparison of addition cohort with two titration subgroups: 1) titration up to or below intermediate doses and 2) titration to beyond intermediate doses. RESULTS: During the post-treatment modification period, all-cause medication costs were 9% higher (p < 0.0001), while inpatient costs were 14% lower for the addition cohort (p < 0.008) as compared to the up-titration cohort. The total risk-adjusted health care costs were slightly lower but statistically insignificant for the addition cohort compared to the up-titration cohort (ratio of cost = 0.99; p = 0.052). These costs patterns remained similar for both the up-titration subgroups. CONCLUSIONS: While addition of another OAD to the initial OAD regimen may result in higher medication costs, the lower inpatient costs and overall offset in the subsequent total costs may indicate clinical benefits with the add-on treatment. When appropriate and clinically beneficial, physicians may want to consider adding an OAD rather than up-titrating the current OAD, particularly beyond intermediate dose levels.

Human growth hormone treatment: synthesis of literature on product delivery systems and administration practices.

PURPOSE: To synthesize current literature on recombinant human growth hormone (rhGH) use and to identify areas of research that have received little to no attention in light of administration practice and patient perception/behavior. DESIGN AND METHODS: Relevant articles for a systematic review were identified through PubMed. RESULTS: A total of 43 articles were identified: 9 (15.9%) studies on product administration practices and 34 (84.1%) on patient behavior patterns. Patients primarily preferred simple, convenient, and easy-to-use delivery devices. However, literature addressing the effect of convenient product administration practices on treatment outcomes using real-world patient/caregiver data is lacking. PRACTICE IMPLICATIONS: Better understanding of real-world product administration practices will help nurses identify areas of improvement in patient education and training.

Prior authorization for topical psoriasis treatments: is it cost-beneficial for managed care?

OBJECTIVE: The introduction of novel therapeutic options for psoriasis has raised managed care's interest in controlling costs associated with dermatological treatments. Prior authorization (PA) can be a successful way of managing costs. However, experience with topical treatments for acne suggests that PA may not be cost-effective. The role of managed care in dermatology and the potential impact of PA requirements for novel topical therapies for psoriasis are considered. METHODS: Using a model based on recent survey data, total annual cost estimates for a managed care organization to cover psoriasis treatment with a topical agent with or without PA requirements were calculated and compared. Costs for treatment and administrative costs associated with PA processes were included. The model assumed 68 000 insured patients required treatment (with an additional 1% to account for abuse/misuse), an average wholesale price of $100 per prescription (each prescription filled 4x/year), and a cost of $20 to process each PA request. RESULTS: The total annual costs were $28 573 600 when PA was required and $27 472 000 when PA was not required. Thus, there was a total annual loss to the managed care organization of $1 101 600 associated with PA requirements. CONCLUSIONS: Requiring PA for novel topical treatments for psoriasis, such as the new two-compound product containing calcipotriene and betamethasone dipropionate (Taclonex((R)); Warner Chilcott (US), Inc.; marketed as Daivobet((R))/Dovobet((R)) outside US by LEO Pharma), is not likely to be cost-effective for a managed care organization.

Prescribing patterns for topical retinoids: analyses of 15 years of data from the national ambulatory medical care survey.

OBJECTIVE: To examine the prescribing patterns of topical retinoids in the United States. METHODS: A retrospective, cross-sectional study was employed. Data from the National Ambulatory Medical Care Survey (1990-2004) were used. The impact of patient diagnosis of acne and other covariates on the probability of getting a retinoid prescription was examined using weighted multivariate logistic regression models. RESULTS: Among the national cohort of patients aged 10 years and older (number of patient visits = 11.7 billion), 41.5 million patients received a topical retinoid prescription. In the retinoid cohort, more than 70% of patients had a diagnosis for acne vulgaris. Diagnosis of acne vulgaris was the strongest predictor of getting a retinoid prescription after controlling for other covariates (OR: 43.39; 95% CI: 32.44, 58.02). CONCLUSIONS: Requiring prior authorization for topical retinoids for all age groups seems unwarranted and may not be cost-beneficial for the managed care organizations based on these and previous findings.

Difficult to swallow: patient preferences for alternative valproate pharmaceutical formulations.

OBJECTIVE: To determine the degree to which swallowing valproate (VP) tablets is an issue, the proportion of patients who would prefer an alternative formulation, and the predictors of preference. METHODS: A quantitative telephone survey of eligible adults (n = 400, >/=18 years old) who currently take (n = 236) or previously took (n = 164) VP tablets within the past 6 months was conducted. RESULTS: More than half of the patients indicated that VP tablets were 'uncomfortable to swallow' (68.5%, n = 274) and were 'very interested' (65.8%, n = 263) in medications that were easier to swallow. When choosing conceptually between taking VP tablet once/day or an equally safe and effective but significantly smaller soft gel capsule twice per day, the 82.8%, (n = 331) preferred the soft gel capsule. In the multivariate regression analysis, perceiving soft gel capsules to be easier to swallow (OR = 73.54; 95% CI = 15.01 to 360.40) and taking VP more frequently (OR = 2.02; 95% CI = 1.13 to 3.61) were significant predictors of soft gel capsule treatment preference. CONCLUSION: VP users would prefer a formulation that is easier to swallow, even if it is needed to be taken twice per day. When choosing between medications with similar efficacy and safety, physicians can consider patient preferences to optimize conditions for medication adherence.

Adjuvant hormonal therapy use among insured, low-income women with breast cancer.

PURPOSE Use of adjuvant hormonal therapy, which significantly decreases breast cancer mortality, has not been well described among poor women, who are at higher risk of cancer-related death. Here we explore use of adjuvant hormonal therapy in an insured, low-income population. METHODS A North Carolina Cancer Registry-Medicaid linked data set was used. Women with hormone receptor-positive or unknown, nonmetastatic breast cancer, diagnosed between 1998 and 2002, were included. Main outcomes were (1) prescription fill within 1 year of diagnosis, (2) adherence (medication possession ratio), and (3) persistence (absence of a 90-day gap in prescription fills over 12 months). Results The population consisted of 1,491 women (mean age, 67 years). Sixty-four percent filled prescriptions. Predictors of prescription fill included the following: older age (odds ratio [OR], 1.01; P = .017), greater number of prescription medications (OR, 1.06; P < .001), nonmarried status (OR, 1.82; P = .001), higher stage (OR, 1.83; P < .001), positive hormone receptor status (positive v unknown, OR, 1.98; P < .001), not receiving adjuvant chemotherapy (OR, 1.74; P = .001), receipt of adjuvant radiation (OR, 1.55; P = .004), and treatment in a small hospital (OR, 1.49; P = .024). Adherence and persistence rates were 60% and 80%, respectively. Nonmarried status predicted greater adherence (OR, 1.90; P = .006) and persistence (OR, 1.75; P = .031). CONCLUSION Prescription fill, adherence, and persistence to adjuvant hormonal therapy among socioeconomically disadvantaged women are low. Improving use of adjuvant hormonal therapy may lead to lower breast cancer-specific mortality in this population.

Understanding medication compliance and persistence from an economics perspective.

OBJECTIVES: An increased understanding of the reasons for noncompliance and lack of persistence with prescribed medication is an important step to improve treatment effectiveness, and thus patient health. Explanations have been attempted from epidemiological, sociological, and psychological perspectives. Economic models (utility maximization, time preferences, health capital, bilateral bargaining, stated preference, and prospect theory) may contribute to the understanding of medication-taking behavior. METHODS: Economic models are applied to medication noncompliance. Traditional consumer choice models under a budget constraint do apply to medication-taking behavior in that increased prices cause decreased utilization. Nevertheless, empiric evidence suggests that budget constraints are not the only factor affecting consumer choice around medicines. Examination of time preference models suggests that the intuitive association between time preference and medication compliance has not been investigated extensively, and has not been proven empirically. The health capital model has theoretical relevance, but has not been applied to compliance. Bilateral bargaining may present an alternative model to concordance of the patient-prescriber relationship, taking account of game-playing by either party. Nevertheless, there is limited empiric evidence to test its usefulness. Stated preference methods have been applied most extensively to medicines use. RESULTS: Evidence suggests that patients' preferences are consistently affected by side effects, and that preferences change over time, with age and experience. Prospect theory attempts to explain how new information changes risk perceptions and associated behavior but has not been applied empirically to medication use. CONCLUSIONS: Economic models of behavior may contribute to the understanding of medication use, but more empiric work is needed to assess their applicability.

Depressive symptomatology, medication persistence, and associated healthcare costs in older adults with glaucoma.

PURPOSE: Depressive symptoms may impact patients' medication use behavior and utilization of healthcare services. This study examined association between depressive symptoms and Glaucoma medication-related persistence and predictors of associated healthcare charges in older adults with primary open angle Glaucoma. METHODS: This study used a retrospective cohort of older adults with primary open angle Glaucoma who completed health status assessment, used Glaucoma medications, and were enrolled in a Medicare Health Maintenance Organization. Baseline assessment surveyed patients on demographics, healthcare service utilization in year before enrollment, lifestyle, and quality of life. Demographic, clinical, and utilization-related economic variables were retrieved from administrative claims database of patients' Health Maintenance Organization. Survival techniques were used to measure time to discontinuation (persistence) and Center for Epidemiologic Studies Depression Scale a 20-item self-reporting scale assessed depressive symptomatology on a range of 0 to 60. Associations were examined using mixed-model regression approach. Sensitivity analysis that considered log-transformed and untransformed specifications of cost variable tested model appropriateness. RESULTS: In total 268 patients were followed for 2 years (N=536). After controlling for potential confounders and temporal effects, depressive symptomatology was associated with decreased Glaucoma medication-related persistence (P<0.005). Patients who lived alone and had cardiovascular disease showed higher odds of experiencing depressive symptoms (P<0.005). Healthcare charges increased with number of comorbidities and prescriptions (P<0.005). CONCLUSIONS: Presence of depressive symptoms in patients lead to poor Glaucoma medication use behavior. Healthcare expenditures increased for patients with increase in comorbidities. Plan enrollees' risk assessment offers advantage of improving health outcomes and reduces healthcare utilization.

Medication adherence and health care costs with the introduction of latanoprost therapy for glaucoma in a Medicare managed care population.

BACKGROUND: Latanoprost, a prostaglandin inhibitor, is increasingly being used in the therapeutic management of glaucoma. However, there is scant literature examining the cost and outcome ramifications of latanoprost. OBJECTIVES: This study examined the medication use behavior (medication-related persistence and adherence rates) and costs associated with the introduction of latanoprost therapy in a treatment-naive older population (aged >or=65 years) enrolled in Medicare. METHODS: The study employed a retrospective observational cohort design and used administrative claims data from a Medicare health maintenance organization (HMO), which offered complete coverage to enrollees, including prescription benefits. The case group consisted of patients with glaucoma who began latanoprost therapy. The control group consisted of enrollees with glaucoma who started any therapy other than latanoprost. Both groups were followed up for 1 year before and after initiation of therapy. Bivariate and multivariate techniques incorporating health care utilization in the year before the start of new therapy were used to determine the study outcomes. RESULTS: The case group comprised 101 patients (mean age, 77.60 years), while the control group included 168 patients (mean age, 77.59 years). There were no significant differences across the 2 groups with respect to age, sex, general health scores on the 12 item Short-Form Health Survey, severity of comorbidity, or the proportion of respondents with perception of worsened health. Introduction of latanoprost therapy was associated with higher medication persistence (hazard ratio, 0.90; 95% CI, 0.68-0.98) and adherence rates (mean [SD], 0.51 [0.26] vs 0.40 [0.25]; P < 0.001) compared with patients starting other glaucoma medication. Furthermore, there were no additional increases in total health care costs in the entire population associated with the introduction of latanoprost therapy, after adjusting for group and time effects, as well as other confounders (mean [SD], $4718.24 [$8982.92] vs $4046.55 [$6505.39]). CONCLUSIONS: Latanoprost therapy offered improved medication use behavior in these older adults enrolled in a Medicare HMO. There were no significant additional increases in overall health care costs as a result of introduction of latanoprost therapy, after adjusting for group and time effects, as well as other baseline confounders in this study cohort.

Prior authorization of newer insomnia medications in managed care: is it cost saving?

STUDY OBJECTIVES: New pharmacotherapeutic treatment options are available to treat patients with 1 or more insomnia symptoms. However, these new pharmaceuticals are subject to a variety of managed-care tools, such as prior authorizations, that may restrict access to these medications. The objective of this study was to evaluate the economic consequences to a health plan that requires prior authorization for nonbenzodiazepine medications approved for the treatment of insomnia characterized by difficulties both falling and staying asleep. METHODS: An economic model was constructed to determine the effects of a typical prior-authorization program across a hypothetical managed-care population. Model parameters were derived from national estimates and a literature review. RESULTS: Economic consequences of a prior-authorization program were based on a hypothetical managed-care plan with 500,000 insured patients. An estimated acquisition cost of $300 per 100 tablets of medication requiring prior authorization, $40 to process each priorauthorization request, and prior-authorization rejection rates of 2% to 5% were considered. Using the default-model inputs of the hypothetical plan characteristics and costs, the economic model estimated a loss of $600,000 to $700,000 per year to the health plan. In a 3-way threshold sensitivity analysis when prior-authorization rejection rate was increased to 5%, the cost of each request in the prior-authorization program was decreased to $20, and the cost of a first-generation nonbenzodiazepine was decreased to a generic price (i.e. $100 per prescription), the model continued to show a net loss to managed care in each case. CONCLUSIONS: This model showed that requiring prior authorization for newer sleep treatments might not be a cost-saving strategy for managed-care organizations.

Measures used in specifying psoriasis lesion(s), global disease and quality of life: a systematic review.

OBJECTIVE: To assess which measures are utilized to quantify lesions, disease severity, and quality of life in the current literature on psoriasis vulgaris. METHODS: A MEDLINE search was performed with the keyword 'psoriasis' and the following limits 'All Adult: 19+ years', 'published in the last 5 years', 'English', 'Randomized Controlled Trial', and 'Humans'. The 'Methods' section of the individual articles were reviewed for inclusion criteria that described the study participants' state of psoriasis or disease generalization at baseline, methods used to classify or measure psoriasis during the study, the primary and secondary endpoints, and the quality of life measures utilized in each study. RESULTS: A search resulted in a total of 180 articles, out of which 134 were utilized for the review. The criteria most commonly utilized were 'moderate to severe psoriasis', 'BSA >/=10%', 'mild to moderate psoriasis', and 'severe psoriasis'. PASI was the most commonly used measure to describe the extent of psoriasis. The most common QoL measure used was DLQI, being used in 54.8% of the articles that used some form of QoL measure/s. DISCUSSION: Various measures are being utilized for the same purpose of generalizing disease/lesion severity and determining 'quality of life'.

How PAs improve access to care for the underserved.

OBJECTIVE: Increasing health care costs and inaccessibility to care create barriers to physicians' services. The physician assistant (PA) profession developed in part to help care for underserved populations. The objective of this study was to test the hypothesis that poorer patients in outpatient clinics are more likely to see PAs than physicians. METHODS: A retrospective analysis of National Ambulatory Medical Care Survey data (1997-2003) on outpatient physicians and their office staff was carried out. Weighted logistic regression analysis was used. RESULTS: After adjusting for covariates such as patient age, gender, race, year of visit, and region, patients covered by Medicare insurance had lower odds of visiting PAs compared to patients possessing private insurance (odds ratio [OR]: 0.48; 95% confidence interval [CI]: 0.29-0.81). Further, patients who paid out-of-pocket had higher odds of visiting PAs compared to patients with private insurance, after adjusting for potential confounders (OR: 1.37; CI: 1.18-1.77). Patients in rural areas were more likely to visit PAs than were patients in urban areas (OR: 2.02; CI: 1.31-3.14). CONCLUSION: Considerable use is made of PAs in all settings, and they tend to be utilized in otherwise underserved, rural populations who do not have health insurance.

Outcomes associated with the use of biologic agents in moderate to severe psoriasis.

An estimated 2.1% of Americans have psoriasis and approximately 30% of them have moderate to severe psoriasis. Although the disease is not associated with mortality, it has a significant impact on health-related quality of life among patients. Several therapies are available for psoriasis including topical agents, phototherapy, and systemic medications. Recently, effective yet expensive biologic agents have been added as treatments for moderate to severe psoriasis. Biologics are recommended in patients for whom all other available treatment options have failed. This extensive review provides important information on the clinical and patient-related outcomes associated with the biologic agents used in psoriasis.

Physician and patient characteristics associated with outpatient breast cancer screening recommendations in the United States: analysis of the National Ambulatory Medical Care Survey Data 1996-2004.

BACKGROUND: The primary goal of breast cancer screening tests is to find cancer at an early stage before a person has any symptoms. Evidence suggests that screening examinations such as mammography and clinical breast examinations (CBE) are effective in early detection of breast cancer. Physician recommendation is an important reason many women undergo screening. This study examined the physician and patients related factors associated with physician recommendations for breast cancer screening in the United States (US) outpatient settings. METHODS: This cross-sectional study used data from the National Ambulatory Medical Care Survey (NAMCS) from 1996-2004. Women aged >or=40 years were included in the study sample. Multivariate logistic regression analyses were used to study the objectives. RESULTS: Weighted analysis indicated that physicians performed 198 million CBEs and made 110 million mammography recommendations over the study period (1996-2004). Patients' age, duration of visits, history of previous breast cancer diagnosis, and source of insurance were significant predictors of screening recommendations in this population. Obstetricians and gynecologists were more likely to perform a CBE and recommend mammography than other specialty physicians. CONCLUSIONS: These findings indicated that there were certain disparities regarding the physician recommendations of breast cancer screening for women in the US outpatient settings.
