Abstract
BACKGROUND AND OBJECTIVES Improvement in seizure control after epilepsy surgery could lead to lower health care resource use and costs, but it is uncertain whether this could offset the high costs related to surgery. This study aimed to evaluate phase-specific and cumulative long-term health care costs of surgery compared to medical therapy in children with drug-resistant epilepsy from the health care payer perspective. METHODS Children who were evaluated for epilepsy surgery and treated with surgery or medical therapy from 2003 to 2018 at the Hospital for Sick Children in Toronto were identified from chart review and linked to their health administrative databases in Ontario, Canada. Inverse probability of treatment weighting with stabilized weights was used to balance the baseline covariates between the 2 groups. Patients were assigned to presurgery, surgery, short-term (first 2 years), intermediate-term (2-5 years), and long-term (>5 years) postsurgery care phases on the basis of treatment trajectory. Phase-specific and cumulative long-term health care costs were evaluated. Costs were converted from Canadian to US dollars year 2018 value. RESULTS There were 372 surgical and 258 medical patients. Costs were higher in surgical than medical patients for presurgery (3 and 39 weeks), surgery, and short-term care phase, and the attributable costs of surgery per 7 patient-days were $1,602 (95% CI $1,438-$1,785), $172 (95% CI $147-$185), $19,819 (95% CI $18,822-$20,932), and $28 (95% CI $22-$32), respectively. Costs were lower in surgical patients for intermediate- and long-term care phase, and the attributable costs were -$72 (95% CI -$124 to -$35) and -$94 (95% CI -$129 to -$63), respectively. In surgical patients, costs were highest for surgery followed by presurgery care phase, with hospitalizations accounting for the highest cost component. In medical patients, costs increased gradually from presurgery to long-term care phase. Cumulative costs were higher for surgical than medical patients in the first 7 years after surgery, but from 8 years on, costs were lower for surgical patients. DISCUSSION This study demonstrated the long-term economic benefits of epilepsy surgery compared to medical therapy for the health care system with the use of real-world data, which would justify the high costs of surgery. The results will support future economic evaluation comparing minimally invasive treatment such as laser therapy to surgery.

Abstract
Aim: To describe the characteristics and medication treatment patterns, healthcare resource utilization (HRU), and associated costs in Japanese patients with systemic lupus erythematosus (SLE).Methods: Claims data from the Japan Medical Data Center (JMDC) database were used to identify patients with SLE-related claims from 2010 to 2017. Algorithms were developed to retrospectively categorize patients by disease severity, treatment experience, and SLE-related manifestations such as lupus nephritis and central nervous system lupus. Descriptive and multivariate analyses were used to describe treatment pattern and estimate HRU and associated costs for the SLE cohort overall and by disease severity and complications.Results: Among 4,733 eligible patients, 2,072 (43.8%) were treatment naïve, 2,214 (46.8%) were previously treated for SLE, and 447 (9.4%) did not receive any treatment. Mean (SD) age of the total SLE cohort was 45.2 (13.1) years and mean (SD) follow-up duration was 1,137.3 (758.0) d. Based on disease severity, 1,383 (29.2%) patients had mild, 2,619 (55.3%) patients had moderate, and 731 (15.4%) patients had severe SLE. Patients on glucocorticoids (both oral and parenteral) received add-on medications the most (35.5%, p < .001). Mean annual cost per SLE patient in the post-index period, inclusive of hospitalizations, outpatient visits, and pharmacy was ¥436,836; ¥1,010,772; and ¥2,136,780 for patients with mild, moderate, and severe SLE, respectively.Limitations: The database only captured information on patients up to 75 years of age. Due to the nature of the database, biases regarding conditions that attribute to the spectrum of SLE severity, flare incidences, or individual physical status cannot be ruled out.Conclusions: This study describes the treatment patterns and economic burden experienced by Japanese patients with SLE. The results highlight an unmet need to derive better treatment strategies for patients with SLE to effectively address the disease burden in Japan.

Abstract
BACKGROUND Increased survival in patients with systemic lupus erythematosus (SLE) has shifted attention towards the burden that SLE imposes upon patients, healthcare systems and society. New interventions aimed at alleviating this burden will require economic evaluation. A summary of the current evidence of the humanistic and economic burden provides a platform for such subsequent studies. OBJECTIVE The objective of this study was to systematically review the current evidence on the humanistic and economic burden of SLE in terms of health-related quality of life (HR-QOL) and costs, and summarize the evidence on the factors found to be associated with this burden. METHODS Relevant literature for the years 1990 to February 2011 were obtained from systematic searches of MEDLINE, EMBASE and Web of Science. Articles reporting the humanistic (preference-based outcome measures or an SLE disease-specific HR-QOL measure) or economic burden (costs) of SLE in adult populations published in English were identified. The following exclusion criteria were applied: studies specifically examining lupus nephritis, SLE not being the main condition of focus (e.g. SLE is a co-existing condition), studies focusing on diagnostics or tests (including genetics and antibodies), mixed patient groups from which SLE could not be separated, paediatric populations, case studies, abstract unavailable, and non-English language studies. Estimates of the burden in terms of either HR-QOL or costs were extracted, tabulated and reported narratively. Annual cost figures were also converted into year 2010 US dollars using the consumer price index (CPI) and the purchasing power parity (PPP) conversion factor to allow for greater comparability across studies. Evidence on the factors found to be independently associated with either HR-QOL or costs was also examined. RESULTS Of the 1969 studies initially identified as being potentially relevant, 32 papers were retained for the final review. Eighteen of these presented estimates of the burden in terms of HR-QOL, and 14 in terms of the economic cost. Mean utility scores reported on preference-based measures of HR-QOL ranged from 0.6 to 0.75. Mean annual direct costs per patient ranged from US$2,214 to US$16,875, and mean annual indirect cost estimates from US$2,239 to US$35,540 (year 2010 values). Disease activity and damage, along with poor mental and physical health, were repeatedly reported to predict both reduced HR-QOL and increased costs. CONCLUSIONS The burden of SLE was found to be substantial, not only for patients but also for the health services that provide care for them. Treatments that are able to alleviate this burden are therefore likely to be highly valued by sufferers. After an extended period in which few therapeutic advances were made or treatments licensed, fundamental developments are finally being made. These new treatments will need to be evaluated for both clinical and cost effectiveness if their use is to be widely implemented.

Abstract
BACKGROUND Individuals' valuation of changes in health states in monetary terms have been measured by examining changes in the direct and indirect costs of disease and by the willingness-to-pay (WTP) methodology. METHODS In 2002, a 2-part study was conducted in Quebec. In one part of the study, 121 rheumatoid arthritis (RA) patients from the McGill University Health Centre were mailed the Stanford Cost Assessment Questionnaire, which enabled the elicitation of direct costs and indirect costs, according to the friction cost and the human capital methods. The other part was a phone survey conducted in a representative sample of the general population and in the same sample of patients, aiming to elicit the societal WTP for a complete cure of RA in the context of 2 different scenarios: a public coverage or private insurance. These estimates were then compared. RESULTS Estimates of the cost of illness of RA ranged from 11,717 to 28,498 Canadian Dollars (CAD) depending on the method. These estimates are higher than those previously published in Canada from the 1990s, which is partly due to the recent and costly biological therapies and to a change in the measurement of productivity losses. These estimates are somewhat lower than the societal WTP elicited from the WTP survey, that is, 26,717 and 36,817 CAD per RA case, depending on the public or private health insurance context in which the cure would be available. CONCLUSION Given that neither method is ideal, data from both methods would provide an important sensitivity analysis when monetary estimates of health state changes are required.

Abstract
OBJECTIVE To track changes in the proportion of persons ages 18-64 with systemic lupus erythematosus (SLE) who were employed from diagnosis through 2004, to estimate changes in annual work hours during this time, and to describe risk factors for work loss among those employed at diagnosis. METHODS A structured telephone survey was administered to a cohort of 982 persons with SLE, which was assembled between 2002 and 2004. Of the 900 enrolled in 2002-2003, 832 (92%) were re-interviewed in 2004. We tabulated the proportion employed at diagnosis, at baseline interview, and at followup in 2004. Among individuals employed at each time frame, we estimated the hours of work per year. We then used the Kaplan-Meier method to estimate time until work loss among individuals employed at diagnosis and Cox proportional hazards regression to describe the risk factors for such work loss. RESULTS Between diagnosis and followup interview, the proportion employed declined from 74% to 54%. Over the same period, hours of work per year declined by 32.2% among all individuals with a work history, but by only 1% among those continuously employed. Among individuals working at diagnosis, the proportion employed declined by 15% and 63% after 5 and 20 years, respectively. Demographics (age, sex, and education) and work characteristics (physical and psychological demands of jobs and level of control) were the principal determinants of work loss. CONCLUSION Total cessation of employment, rather than reduced hours among employed persons, accounts for most of the decline in annual work hours among persons with SLE.

Abstract
OBJECTIVE To evaluate the efficacy and safety of adding intramuscular (IM) gold to the treatment regimen of patients with rheumatoid arthritis (RA) who have a suboptimal response to methotrexate (MTX). METHODS A randomized, double-blind, double-observer, placebo-controlled multicenter trial of 48 weeks was conducted. Sixty-five RA patients who had a suboptimal response to >/=12 weeks of MTX therapy were randomly assigned to receive weekly IM gold or placebo in addition to MTX. Gold was administered according to a standard protocol developed for the study. The primary outcome measure was the percentage of patients who met the American College of Rheumatology (ACR) 20% improvement criteria (achieved an ACR20 response) at week 48. Secondary outcomes included the percentages of patients achieving ACR50 and ACR70 responses, the individual criteria that make up the primary outcome, quality of life, direct and indirect health care costs, intraarticular steroid use, and adverse events, among other measures. Statistical analyses were based on an intent-to-treat strategy. RESULTS Sixty-one percent of patients receiving gold achieved an ACR20 response compared with 30% of patients receiving placebo (chi(2) = 6.04, P = 0.014; logistic regression odds ratio 3.64 [95% confidence interval 1.3, 10.4], P = 0.016). Twenty-six percent of patients receiving gold achieved an ACR50 response compared with 4% of patients receiving placebo (P = 0.017), and 21% of patients receiving gold achieved an ACR70 response compared with 0% of patients receiving placebo (P = 0.011). From both clinical and cost-effectiveness perspectives, gold was the preferred and dominant strategy. Study treatment was discontinued in 23 patients (14 in the placebo group compared with 9 in the gold group; P = 0.022) due to loss to followup, adverse events, or lack of efficacy. CONCLUSION In RA patients with a suboptimal response to MTX, adding weekly IM gold causes significant clinical improvement. Adverse events were minor, and IM gold-related adverse events led to discontinuation in only 11% of the gold group over 48 weeks.

Abstract
For a long time, systemic lupus erythematosus (SLE) was considered a potentially deadly disease. Since the introduction of immunosuppressive therapy, the life expectancy and the quality of life of patients suffering from lupus erythematosus has been dramatically improved. Today, the 5-year survival rate for SLE varies between 50% and 95%. Still, not all patients benefit equally from medical advances. Ethnic and/or socioeconomic minorities show severely disadvantageous prognosis or outcome in various studies. A substantial reduction in the quality of life as well as unemployment are other frequent side effects of this disease. Vocational handicaps related to discoid lupus erythematodes (DLE) was seen in nearly 45% of the patients. Therefore, the management of lupus erythematosus patients requires interdisciplinary cooperation between physicians, psychologists and social workers. The major aim of this article is to summarize the history of lupus erythematosus on the one and the other hand to consider the role of the socioeconomic factors influencing the prognosis of systemic and cutaneous lupus erythematosus.

Abstract
OBJECTIVE To investigate whether ethnicity was associated with differences in Medicaid eligibility, health care utilization, and direct medical costs in a systemic lupus erythematosus (SLE) population. METHODS A retrospective analysis of California Medicaid claims data was conducted on patients with SLE. Patient eligibility and month-by-month utilization and costs were computed and compared across ethnic groups. Descriptive statistics are presented. A mixed regression model on patient-level data was used to verify the trends of the aggregate data, controlling for covariates. A survival regression model on time to ineligibility was used to show eligibility patterns adjusted for covariates. RESULTS Hispanic patients were less likely to have a lengthy eligibility period as compared with other cohorts (approximately 50% versus 70% eligible at month 36, respectively). As treatment progressed, Hispanics generated lower total costs than other cohorts. Results for inpatient frequency, prescription costs, and outpatient/physician/supply (Part B) costs followed similar patterns. Mixed regression model findings revealed that when adjusted for age, sex, and aid program, total costs for Hispanic patients decreased as the length of care increased, in contrast to other ethnic groups. The interaction between ethnicity and treatment progression measured by quarter was significant (P <0.0001), but ethnicity as a main effect was not (P=0.091). This suggests that differences in total costs are small initially, but as the followup period extends, Hispanic patients experience lower total costs as compared with other ethnic groups. CONCLUSION These California Medicaid program data reinforce the importance of investigating treatment differences in ethnic groups with SLE.

Abstract
OBJECTIVE Systemic lupus erythematosus (SLE) is an uncommon, clinically complex disease for which prior experience treating similar patients may be particularly important. This study was undertaken to determine if physician volume is associated with the outcome of hospitalization of patients with SLE. METHODS Data on in-hospital mortality in a population-based sample of 15,509 patients with SLE ages 18 years or older who were hospitalized in 2000, 2001, or 2002 in New York or Pennsylvania were obtained from state health planning agencies. Risks of in-hospital mortality were examined in relation to the average annual number of patients with SLE hospitalized by the admitting physician. RESULTS Physician volume was inversely associated with mortality. Mortality was 4.1% among patients of physicians who treated <1 hospitalized patient with SLE per year, 3.5% among patients of physicians who treated 1-3 patients per year, and 2.5% among patients of physicians who treated >3 patients per year. After adjustment for demographic characteristics, severity of illness, and hospital characteristics, the mortality risk was 20% lower among patients in the middle category of physician volume (odds ratio 0.80, 95% confidence interval 0.66-0.96, P =0.02), and 42% lower among patients in the highest category of physician volume (odds ratio 0.58, 95% confidence interval 0.42-0.82, P = 0.002), compared with patients in the lowest category. The association was stronger among patients with nephritis (n = 2,673), for whom the adjusted odds of mortality were approximately 60% lower among those in the highest category of physician volume. CONCLUSION Our findings indicate that higher disease-specific physician volume is associated with lower risks of in-hospital mortality in patients with SLE.

Abstract
OBJECTIVE To provide estimates of the total medical care expenditures and earnings losses associated with arthritis and other rheumatic conditions (AORC), as well as the increment in such costs specifically attributable to these conditions, in the US in 1997. METHODS The estimates were derived from the 1997 Medical Expenditures Panel Survey (MEPS), a national probability sample of 14,147 households including 34,551 persons, of whom 4,776 self-reported arthritis. After weighting, those who self-reported AORC represent 38.4 million persons. We tabulated all medical care expenditures of the adult MEPS respondents, stratified by arthritis and comorbidity status, and then used regression techniques to estimate the increment in health care expenditures attributable to AORC, after taking comorbidity, demographic characteristics, and insurance status into account. Using the same methods, we also estimated the magnitude of the earnings losses sustained by persons of working ages (18-64 years) who had AORC. RESULTS Persons with AORC incurred mean total medical care expenditures of 4,865 dollars (total 186.9 billion dollars). The largest components of these expenditures were inpatient care (39%), ambulatory care (29%), and prescriptions (14%). The mean increment in medical care expenditures specifically attributable to AORC among those ages 18 years and older was 1,391 dollars(total approximately 51.1 billion dollars). Persons with AORC ages 18-64 years earned 3,812 dollars less on average than did other persons of these ages (total 82.4 billion dollars). Of this average, 1,579 dollars was attributable to the AORC (total 35.1 billion dollars). CONCLUSION In 1997, persons with AORC incurred direct and indirect costs of 269.3 billion dollars, of which 86.2 billion dollars was attributable to these conditions.

Abstract
OBJECTIVE To compare health resource utilization in patients with diabetes between the U.S. and Canada. RESEARCH DESIGN AND METHODS We combined measures of health care utilization, personal, demographic, health status, functional status, and comorbid conditions from the current National Health Interview Survey (U.S.) and the National Public Health Survey (Canada). A binary logistic regression analysis was used to examine how country of residence influences the probability of accessing health care resources in adult Caucasian subjects after controlling for potential confounders. RESULTS Subjects from Canada (n = 521) were more likely to have contact with a general physician (odds ratio [OR] 4.01, 95% CI 2.26-7.14), eye specialists (1.46, 1.08-1. 98), and any physician (3.02, 1.03-8.84) in the past year than their American counterparts (n = 825) but were less likely to have had contact with other medical specialists (0.33, 0.24-0.46). Subjects in Canada were also more likely to have been hospitalized overnight (1.79, 1.17-2.75) or to have contact with a health care professional in the previous 12 months (3.35, 1.01-12.81). CONCLUSIONS Significant disparities exist in health service utilization for adult Caucasian individuals with diabetes in Canada versus the U.S. after controlling for various confounders. From what is known regarding optimal treatment of diabetes, those with diabetes in the U.S. have a greater chance of not receiving recommended care.

Abstract
OBJECTIVE To compare the glycemic control of patients with type 1 diabetes treated in the U.S. and Canada. RESEARCH DESIGN AND METHODS A large multicenter randomized clinical trial conducted in the U.S. and Canada was analyzed. Patients with type 1 diabetes, screened from 1983 to 1989 for enrollment in the Diabetes Control and Complications Trial (DCCT), were categorized as treated in the U.S. (n = 2,604) or Canada (n = 245). HbA(1c) levels were compared between U.S. and Canadian patients, both before and after adjustment for predictors of HbA(1c). RESULTS In general, volunteers screened for the DCCT were highly educated and following healthy lifestyles. Canadians were somewhat younger (25 vs. 27 years of age, P = 0.002), less likely to be college educated (62 vs. 71%, P = 0.002), more likely to receive care through a family doctor (41 vs. 28%, P = 0.001), and had a higher frequency of out-patient visits (4 vs. 3 per year, P = 0.004). Despite these differences in health care delivery, the mean HbA(1c) at baseline was identical in the two countries (8.9 vs. 9.0, P = 0.40). Adjustment for demographic, lifestyle, and clinical predictors of HbA(1c) yielded similar findings (9.0 vs. 9.2, P = 0.15). Equal percentages of American and Canadian patients who were screened ultimately entered the trial (21 vs. 19%, P = 0.20), and those randomized to conventional care achieved similar mean HbA(1c) levels (9.1 vs. 9.2, P = 0.50). CONCLUSIONS Differences in care delivery patterns do not yield large differences in glycemic control for patients with type 1 diabetes who were recruited in the U.S. and Canada for a large randomized trial.

Abstract
OBJECTIVE To compare disease-related medical care and productivity costs, and utilities, in 482 patients with rheumatoid arthritis randomised to receive leflunomide, methotrexate or placebo during a 12-month period. DESIGN AND SETTING Prospective pharmacoeconomic analysis of a 1-year randomised double-blind trial set in North America. PERSPECTIVE Societal and the Ontario Ministry of Health. METHODS Information on healthcare resources, out-of-pocket expenses, loss of working time and time spent on chores, related to the disease or the medication, were collected at 4-week intervals and at study discontinuation. Rating scale and standard gamble (SG) utilities (0 = worse; 100 = best) were collected at baseline and at 6 and 12 months or study exit. Medical care costs in Canadian dollars (Can dollars) were calculated using Ontario reimbursement schedules. US patients' expenses were converted to Can dollars using 1995 purchasing power parity. Lost wages were calculated by age and gender according to 1995 Canadian wage data. All costs were adjusted to 1999 Can dollars and arithmetic mean costs were compared using the nonparametric bootstrap. Analysis of covariance was performed to compare utilities between groups. RESULTS Mean (standard deviation) rating scale values and SG utilities, respectively, for leflunomide, methotrexate and placebo were 67.7 (18.0), 64.8 (18.1) and 57.5 (9.2), and 80.2 (22.1), 83.2 (18.0) and 77.0 (20.5). Both leflunomide and methotrexate had higher rating scale values (p < 0.05) compared with placebo; SG utilities were significantly different between methotrexate and placebo (p < 0.05). Annualised total rheumatoid arthritisb- or drug-related costs for leflunomide, methotrexate and placebo, respectively, were Can dollars 1761, Can dollars 1280 and Can dollars 1324, and medical care costs were Can dollars 753, Can dollars 620 and Can dollars 167 (all costs exclude drug acquisition and monitoring costs). Annual drug acquisition/ routine monitoring costs were estimated, respectively, at Can dollars 3853/Can dollars 483 for leflunomide and Can dollars 258/Can dollars 599 for methotrexate. Differences between overall costs (excluding drug acquisition and monitoring costs) and medical care costs were not statistically significant. The costs of treating patients with leflunomide were significantly higher than for methotrexate when drug acquisition and monitoring costs were included (p < 0.0001). CONCLUSIONS No statistically significant differences in utilities could be found between leflunomide or methotrexate. When drug monitoring and acquisition costs are excluded, leflunomide has an otherwise similar economic profile compared with methotrexate, the current gold standard. The acquisition cost of leflunomide is a driving factor in increasing the costs of therapy. These higher costs need to be assessed relative to the therapeutic value of leflunomide.

Abstract
OBJECTIVE To provide estimates of all medical care expenditures on behalf of persons with musculoskeletal conditions in the United States in 1996, to estimate the increment in expenditures attributable to the musculoskeletal conditions among such persons, and to ascertain the impact of the presence or absence of health insurance and/or managed care on such expenditures. METHODS The estimates were derived from the Medical Expenditure Panel Survey (MEPS), a national probability sample of 9,488 households, which includes responses from 21,571 persons. In the MEPS, respondents are surveyed every 6 months to report on medical care utilization and health care expenditures. Of the 21,571 persons surveyed, 4,161 reported having 1 or more musculoskeletal conditions. After weighting the data, these 4,161 individuals were inferred to represent 53.935 million persons in the nation as a whole. We tabulated all medical care expenditures of these individuals, stratified by comorbidity status, and then compared their expenditures with those among persons with chronic conditions other than musculoskeletal disease or with no chronic conditions. We then used regression techniques to estimate the increment of health care expenditures attributable to the musculoskeletal conditions. Finally, we used regression to estimate the impact of health insurance status and managed care status on the health care expenditures of the persons with musculoskeletal conditions. RESULTS Per capita medical care expenditures in 1996 averaged $3,578 among persons with musculoskeletal conditions, for a national total of $193 billion, the equivalent of 2.5% of the Gross Domestic Product in that year. The largest components were hospital admissions (37%), physician visits (23%), and prescriptions (16%). Estimates of the per capita increment in total medical care expenditures attributable to musculoskeletal conditions ranged from a high of $723 when controlling for the other medical conditions present, to $364 when controlling for these variables and demographics. Persons with musculoskeletal conditions ages 16-64 who lacked health insurance reported total expenditures of $793, versus $3,249 among those with insurance (P < 0.0001). Among such persons with insurance, expenditures did not differ significantly between those in fee-for-service plans and those in managed care health plans. CONCLUSION Persons with musculoskeletal conditions and health insurance experienced high total expenditures for medical care and high expenditures attributable to the musculoskeletal conditions. Insurance coverage under a managed care plan had no effect on the magnitude of these total expenditures, but lack of insurance coverage did have a significant effect among persons with musculoskeletal conditions.

Abstract
The Canadian health care system is a publicly funded system based on the philosophy that health is a right, not a commodity. The implementation of this perspective is hampered by the fact that the Canadian Constitution makes health care a matter of provincial jurisdiction, while most taxing powers lie in the hands of the federal government. Further problems arise because of Canada's geographic nature and a move to regionalization of provincial health care administration. The issue is compounded by recent developments in reproductive technologies, aboriginal health, changes in consent law, etc.

Abstract
PURPOSE To examine the relationship of adolescent alcohol and drug use over a 5-year period to cumulative health problems in late adolescence and young adulthood. METHODS We prospectively examined self-reported health problems in a sample of adolescents, some of whom received treatment for substance use disorders and had consistently poor substance use outcomes (n = 38), some of whom received treatment for substance use disorders and had positive substance use outcomes (n = 30), and a low alcohol and drug use community comparison group (n = 48). Data regarding health-related problems of these adolescents (mean, 15.9 years; 83% Caucasian; 56.5% female) were collected at 2, 4, and 6 years following initial assessments. RESULTS Alcohol and/or drug involvement severe enough to warrant treatment during adolescence was associated with more cumulative health problems and severe health problems for girls and more cumulative health problems for boys. Protracted and continuous abuse of alcohol and drugs was associated with more cumulative and severe health problems for girls and more severe health problems for boys. CONCLUSIONS These results suggest that significant health problems and concerns are related to both brief and protracted alcohol and drug abuse during adolescence. Health problems will likely become even more evident as early-onset, chronic substance abusers continue to age.

Abstract
Quality of life encompasses the net effects that a patient perceives an illness to have on his or her life. Quality of life commonly includes symptoms, physical functioning, work ability, social interaction, psychological functioning, treatment side effects, and financial costs. In ankylosing spondylitis, although symptoms of pain, stiffness, and fatigue are common and moderately severe, few patients develop severe functional disability and most remain employed. The limited information available suggests that most patients with ankylosing spondylitis have few problems with social interactions, although depression is not uncommon. Direct medical costs of ankylosing spondylitis are low, compared with those of other rheumatic diseases.

Abstract
OBJECTIVE To examine the effectiveness of two telephone intervention strategies for improving the health outcomes of patients with systemic lupus erythematosus (SLE). METHODS Fifty-eight SLE patients were randomly assigned to receive a 6-month telephone counseling intervention using either a treatment counseling (TC) or symptom monitoring (SM) strategy. Health outcomes were assessed using the Fatigue Severity Scale (FSS) and the Arthritis Impact Measurement Scales 2 (AIMS2). RESULTS At the 6-month followup, the mean AIMS2 Physical Function scale and AIMS2 Social Support scale scores were significantly improved (P < 0.05) for the TC group compared to the SM groups. The mean FSS score, AIMS2 Affect score, and AIMS2 Pain score were significantly improved (P < 0.05) for both groups. CONCLUSIONS Telephone interventions, especially using the TC approach, can be effective for improving the functional status of persons with SLE.
