To summarise the relationship between joint damage and functional disability in rheumatoid arthritis (RA) patients.
A systematic review of the literature from 1990 to 2008 was conducted using MEDLINE ...and EMBASE databases. The search strategy focused on RA, joint damage and disability. Only longitudinal studies or randomised clinical trials with 1 year or more of follow-up containing data correlating joint damage and disability were included. The comparisons were categorised in four ways: baseline damage versus disability at end of follow-up (correlation A); damage versus disability measured cross-sectionally at each of several time points (correlation B); changes in damage versus final disability (correlation C) and changes in damage versus changes in disability (correlation D).
From a total of 1902 abstracts, 42 studies met the inclusion/exclusion criteria. More than 50% of the studies that measured baseline damage to later disability (A) reported a statistically significant association. Correlation was significant when measured at multiple time points over time (B; 16/19 studies). Statistically significant associations between changes in damage and either disability at end of follow-up or changes in disability were also found (C and D; 11/13 studies).
While many of the studies did not include multivariate analysis with confounder adjustment, the published evidence indicates a link between joint damage and functional disability and that an increase in joint damage is associated with an increase in disability over time. Treatments to limit progressive joint damage may lead to better joint function and improved patient outcome with less disability.
An implantable drug delivery system (IDDS) provides an alternate route of opioid administration for patients with chronic pain. We collected data on systemic opioid use before and after IDDS ...implantation; patients who successfully discontinued systemic opioids; and physician support of discontinuation.
This was a single-center, retrospective chart review of 99 consecutive patients who used IDDSs for at least six months. Data collection included pre/postimplant systemic opioid use and pain scores, and patient demographic and clinical characteristics.
The study population averaged 67 years of age, was 68% women, and 77% were Medicare beneficiaries. Ninety-five percent of patients had low back pain, and 86% had limb pain. The majority (81%) had pain for >5 years. Failed treatments included epidural injections (74%), lumbar spine surgery (46%), spinal cord stimulation (14%), and facet joint injections (11%), with 84% also reporting significant systemic opioid side-effects. All patients taking long-acting opioids discontinued these within one month of implant. Total systemic opioid elimination was accomplished by 68% of patients at one month postimplant, 84% at one year, and 92% at five years. At one month postimplant, 60% of patients reported decreased pain (mean change: -4.07), and at one year, 64% did (mean change: -3.42).
IDDS can provide significant and lasting pain relief and an alternate route of delivery compared with systemic opioids with their associated side-effects. We demonstrated that systemic opioid elimination could be accomplished after IDDS implantation in the majority of cases through appropriate patient selection, monitoring, and participation.
Purpose. To characterize the economic and quality of life burden of diabetic macular edema (DME) in Canadian patients. Patients and Methods. 145 patients with DME were followed for 6 months with ...monthly telephone interviews and medical chart reviews at months 0, 3, and 6. Visual acuity in the worst-seeing eye was assessed at months 0 and 6. DME-related healthcare costs were determined over 6 months, and vision-related (National Eye Institute Visual Functioning Questionnaire) and generic (EQ-5D) quality of life was assessed at months 0, 3, and 6. Results. Mean age of patients was 63.7 years: 52% were male and 72% had bilateral DME. At baseline, visual acuity was categorized as normal/mild loss for 63.4% of patients, moderate loss for 10.4%, and severe loss/nearly blind for 26.2%. Mean 6-month DME-related costs/patient were as follows: all patients ( n = 135 ), $2,092; normal/mild loss ( n = 88 ), $1,776; moderate loss ( n = 13 ), $1,845; and severe loss/nearly blind ( n = 34 ), $3,007. Composite scores for vision-related quality of life declined with increasing visual acuity loss; generic quality of life scores were highest for moderate loss and lowest for severe loss/nearly blind. Conclusions. DME-related costs in the Canadian healthcare system are substantial. Costs increased and vision-related quality of life declined with increasing visual acuity severity.
No recent Canadian studies with physician- and spirometry-confirmed diagnosis of chronic obstructive pulmonary disease (COPD) that assessed the burden of COPD have been published.
To assess the costs ...associated with maintenance therapy and treatment for acute exacerbations of COPD (AECOPD) over a one-year period.
Respirologists, internists and family practitioners from across Canada enrolled patients with an established diagnosis of moderate to severe COPD (Global initiative for chonic Obstructive Lung Disease stages 2 and 3) confirmed by postbronchodilator spirometry. Patient information and health care resources related to COPD maintenance and physician-documented AECOPD over the previous year were obtained by chart review and patient survey.
A total of 285 patients (59.3% male; mean age 70.4 years; mean pack years smoked 45.6; mean duration of COPD 8.2 years; mean postbronchodilator forced expiratory volume in 1 s 58.0% predicted) were enrolled at 23 sites across Canada. The average annual COPD-related cost per patient was $4,147. Across all 285 patients, maintenance costs were $2,475 per patient, of which medications accounted for 71%. AECOPD treatment costs were $1,673 per patient, of which hospitalizations accounted for 82%. Ninety-eight patients (34%) experienced a total of 157 AECOPD. Treatment of these AECOPD included medications and outpatient care, 19 emergency room visits and 40 hospitalizations (mean length of stay 8.9 days). The mean cost per AECOPD was $3,036.
The current costs associated with moderate and severe COPD are considerable and will increase in the future. Appropriate use of medications and strategies to prevent hospitalizations for AECOPD may reduce COPD-related costs because these were the major cost drivers.
Antipsychotic medications are the mainstay of schizophrenia therapy but may need to be changed over the course of a patient's illness to achieve the desired therapeutic goals or minimize medication ...side effects. Investigations of real-world treatment patterns and economic consequences associated with antipsychotic changes, including switching, are limited.
To describe treatment patterns among patients with schizophrenia who initiated oral antipsychotic medication (OAM) monotherapy and assess switching-related health care resource utilization (HCRU) and costs in US Medicare Advantage and commercially insured patients.
Adults with at least 2 claims with a schizophrenia diagnosis who initiated (or reinitiated after ≥6 months) OAM monotherapy between January 1, 2015, and June 30, 2021, were identified in the Optum Research Database. A claims-based algorithm using timing of therapies and treatment gaps identified medication changes, specifically OAM monotherapy switches, among OAM initiators over a period of up to 7 years. Patients who switched from their initial OAM monotherapy to a second OAM monotherapy (initial OAM switchers) were matched based on clinical and demographic characteristics to OAM initiators who had not switched OAMs; switch-related HCRU and costs (incurred up to 3 months before and 3 months after the initial OAM switch) were compared between matched initial OAM switchers and nonswitchers.
Among 6,425 OAM monotherapy initiators, 1,505 (23.4%) had at least 1 OAM monotherapy switch at any time during follow-up, with a mean (SD) time to first switch of 209 (333) days (median, 67 days), a rate of 0.65 switches per person-year of follow-up, and 56% of first switches occurring within 3 months of OAM initiation. Of all OAM initiators, 947 (14.7%) were initial OAM switchers. Compared with 865 matched nonswitchers, 865 initial OAM switchers had greater mean counts of all-cause medical visits and greater mean counts of schizophrenia-related emergency and inpatient visits and longer inpatient stays per patient per month. Mean (SD) total schizophrenia-related costs per patient per month were $1,252 ($2,602) for switchers compared with $402 ($2,027) for nonswitchers (
< 0.001).
Changes to antipsychotic therapy in our sample of patients with schizophrenia were common, with nearly one-fourth switching OAMs, the majority within the first 3 months of therapy. Initial OAM switchers experienced greater HCRU and costs than nonswitchers. These findings highlight the importance of initiating OAM monotherapy that effectively maintains symptom control and minimizes tolerability issues, which would limit the need to switch OAMs and therefore prevent excess HCRU and treatment costs.
Systemic therapies are commonly used for patients with uncontrolled moderate-to-severe atopic dermatitis (AD) and impaired quality of life (QoL). However, real-world treatment patterns and unmet ...needs of adults with moderate-to-severe AD receiving systemic therapies are poorly quantified.
To evaluate unmet needs in patients with moderate-to-severe AD treated with systemic therapies.
Adults with AD diagnosis in past 5 years and a prescription for systemic treatment or phototherapy in past 6 months were identified from the Optum Research Database. Patients completed a survey about symptoms, treatment, and QoL. Chi-squared and t tests analyzed bivariable comparisons of demographics and outcomes. Spearman's rank-order correlation analyses examined the relationship between frequency of flares and outcomes.
Eight hundred and one participants were included (mean age, 45.2 years; 71.8% female). In the 12 months before baseline survey, 38.3% reported no remission from AD. In the month before baseline survey, 63.6% used topical corticosteroids, and 81.3% of patients experienced 1 or more flares. Patients experiencing flares reported worse Patient-Orientated Eczema Measure (POEM), Peak Pruritus Numeric Rating Scale (NRS), and Dermatology Life Quality Index scores (DLQI), lower treatment satisfaction, and greater work productivity loss than patients without flares (all P < .001). Patients with severe atopic dermatitis reported worse POEM, Peak Pruritus NRS, and DLQI, lower treatment satisfaction, and greater work productivity loss than patients with moderate AD (all P < .001).
Despite receiving systemic therapies, adults with moderate-to-severe AD reported disease symptoms, recurrent flares, and impaired QoL, suggesting unmet therapeutic needs.
Abstract
Aim
Patient‐ and physician‐associated barriers impact the effectiveness of basal insulin (BI) titration in the management of type 2 diabetes (T2D). We evaluated the experiences of patients ...with T2D and physicians with BI titration education.
Materials and Methods
In this observational, cross‐sectional study, patients with T2D and physicians treating patients with T2D were identified by claims in the Optum Research Database and were invited to complete a survey. Eligible patients had 12 months of continuous health‐plan enrolment with medical and pharmacy benefits during the baseline period, and recent initiation of BI therapy. Eligible physicians had initiated BI for ≥1 eligible patient with T2D during the past 6 months.
Results
In total, 416 patients and 386 physicians completed the survey. Ninety per cent of physicians reported treating ≥50 patients with T2D; 66% treated ≥25% of patients with BI. Whereas 74% of patients reported that BI titration was explained to them by a physician, 96% of physicians reported doing so. Furthermore, 20% of patients stated they were offered educational materials whereas 56% of physicians reported having provided materials. Physicians had higher expectations of glycaemic target achievement than were seen in the patient survey; their main concern was the patients' ability to titrate accurately (79%).
Conclusions
There is a marked difference in patients' and physicians' experiences of BI titration education. Novel tools and strategies are required to enable effective BI titration, with more educational resources at the outset, and ongoing access to tools that provide clear, simple direction for self‐titration with less reliance on physicians/health care providers.
