Disease burden and costs for patients with hip and knee osteoarthritis and chronic moderate-to-severe refractory pain on treatment with strong opioids in Spain.

INTRODUCTION AND OBJECTIVES: To determine the disease burden and costs in patients with hip or knee OA and chronic moderate-to-severe refractory pain, receiving strong opioids in Spain. MATERIALS AND METHODS: This was a 36-month longitudinal secondary analysis of the real-word OPIOIDS study. Patients aged ≥18 years with hip or knee OA and chronic moderate-to-severe refractory pain receiving strong opioids were considered. The disease burden included analgesia assessments (NRS scale), cognitive functioning (MMSE scale), basic activities of daily living (Barthel index), and comorbidities (severity and frequency). Costs due to the use of healthcare resources and productivity loss were estimated. RESULTS: 2832 patients were analyzed; age was 72.0 years (SD=14.3), 76.8% were women. Patients had mainly been treated with fentanyl (n=979; 37.6%), tapentadol (n=625; 24.0%), oxycodone (n=572; 22.0%), and buprenorphine (n=425; 16.3%). Pain intensity decreased by 1 point (13.7%), with a 2.6-point decline in the cognitive scale (14.3%, with a 5.3%-increase in patients with cognitive deficit) over a mean treatment period of 384.6 days (SD: 378.8). Barthel scores decreased significantly yielding to a slightly increase in proportion of patients with severe-to-total dependency; 1.2%-2.9%. In the first year of treatment, average healthcare costs were €2013/patient, whereas the average productivity loss cost was €12,227/working-active patient. DISCUSSION AND CONCLUSIONS: Strong opioids resulted in high healthcare costs with a limited reduction in pain, an increase in cognitive deficit, and a slight increase of patients with severe to total dependency over 36 months of treatment.

Introducción y objetivos: Determinar la carga de la enfermedad y los costes en pacientes con osteoartritis de cadera y rodilla y dolor crónico refractario moderado-severo, en tratamiento con opioides mayores en España. Materiales y métodos: Se trata de un subanálisis de 36 meses de duración, procedente del estudio observacional OPIOIDS. Participaron pacientes con una edad ≥18 años, diagnosticados con osteoartritis de cadera y rodilla y dolor crónico refractario moderado-severo, en tratamiento con opioides mayores. La carga de la enfermedad incluyó la evaluación de la analgesia (escala NRS), del funcionamiento cognitivo (escala MMSE), de la capacidad para realizar las actividades de la vida diaria (índice de Barthel) y de las comorbilidades (gravedad y frecuencia). También se estimaron los costes asociados al uso de recursos sanitarios y a la productividad laboral. Resultados: Se analizaron 2.832 pacientes (edad: 72,0 años [DE: 14,3]; mujeres: 76,8%), que habían sido principalmente tratados con fentanilo (n=979; 37,6%), tapentadol (n=625; 24,0%), oxicodona (n=572; 22,0%) y buprenorfina (n=425; 16,3%). La intensidad del dolor disminuyó una unidad (13,7%), con una reducción de 2,6 unidades en la escala cognitiva (14,3% y aumento del 5,3% en los pacientes con déficit cognitivo) durante una media de 384,6 días (DE: 378,8). Las puntuaciones en la escala de Barthel disminuyeron significativamente, con un ligero aumento en la proporción de pacientes con dependencia grave/total, entre 1,2% y 2,9%. En el primer año, los costes sanitarios medios fueron 2.013€/paciente, mientras que los costes medios de pérdida de productividad fueron 12.227€/trabajador. Discusión y conclusiones: El tratamiento con opioides mayores durante 36 meses implicó elevados costes sanitarios, con una eficacia analgésica limitada, un aumento del déficit cognitivo y un ligero aumento de los pacientes con dependencia grave/total.(AU)

Sick Leave and Costs in Active Workers with Chronic Osteoarthritis Pain in Spain: Outcomes of the OPIOIDS Real World Study.

Purpose: To estimate the number of sick leave days and productivity costs in active workers with osteoarthritis (OA) who initiated opioid treatment for moderate/severe chronic pain in clinical practice in Spain. Patients and Methods: This is a secondary analysis of the longitudinal, retrospective OPIOIDS study, using electronic medical records (EMR) of patients aged ≥18 years, who started an opioid treatment for moderate/severe chronic OA pain between 2010 and 2015 after treatment failure with ≥1 first-line drugs (acetaminophen, metamizole and/or nonsteroidal anti-inflammatory drugs [NSAIDs]). The number of days of sick leave and productivity costs were analyzed during a follow-up period of 36 months. Results: A total of 5089 patients with moderate/severe chronic OA pain, aged 56.8 years (standard deviation [SD]: 4.6) (56.6% were female), were analyzed: 73.3% of them started a treatment with weak opioids and 26.7% of them were treated with strong opioids. At 36 months, adherence was 21.0% (strong opioids: 15.4%; weak opioids: 23.0%; p<0.001), and 77% of patients had at least one sick leave related with chronic OA pain, with an average of 93 days off work in all working patients (120.5 days in patients with sick leaves). Besides, 16.9% of the study population had sick leave periods that lasted at least 6 months. Pain reduction was modest (-1.2 points; -4.0%, p<0.001). The cost of sick leave was €2594 patient/year, and factors such as older age (ß=0.043), female sex (ß=0.036), comorbidities (ß=0.035) and strong opioid use (ß=0.031) were associated with higher productivity costs (p<0.05 in all associations). Conclusion: Active workers who started opioid treatment for moderate/severe chronic OA pain showed an increased frequency of sick leave and productivity cost, with a modest effect on pain relief. Older age, female sex, comorbidities, and strong opioids were associated with higher costs for society.

Disease Burden and Costs in Moderate-to-Severe Chronic Osteoarthritis Pain Refractory to Standard of Care: Ancillary Analysis of the OPIOIDS Real-World Study.

INTRODUCTION: To determine the disease burden and costs in moderate-to-severe chronic osteoarthritis (OA) pain refractory to standard-of-care treatment in the Spanish National Health System (NHS). METHODS: Ancillary analysis of the OPIOIDS real-world, non-interventional, retrospective, 4-year longitudinal study including patients aged at least 18 years with moderate-to-severe chronic OA pain refractory to standard-of-care with sequential NSAIDs plus opioids. Burden assessment included measurement of analgesia, cognitive functioning, basic activities of daily living, severity and frequency of comorbidities, and all-cause mortality. Costs accounted for healthcare resource utilization and related costs (year 2018). RESULTS: Records of 13,317 patients were analyzed; 68.9 (14.7) years old, 71.3% (70.5-72.1%) women, 58.1% refractory to NSAID plus weak opioid and 41.9% to NSAID plus strong opioid, accounting for 10.7% (10.5-10.8%) of patients with chronic OA pain. Mean number of comorbidities was 2.9 (1.8) and its severity was 1.8 (1.7). Pain decreased by 0.9 points (12.2%) and cognitive declined by 2.3 points (9.1%, with 4.3% more patients with cognitive deficit) and dependency worsened by 0.4 points (0.5%, with 2.3% more patients with severe-to-total dependence) over a mean treatment period of 188.6 (185.4-191.8) days on NSAIDs followed by 400.6 (393.7-407.5) days on opioids. The adjusted mortality rate was higher in patients with OA taking NSAID plus strong opioids; hazard ratio 1.44 (1.26-1.65; p < 0.001). The 4-year healthcare cost was €7350/patient (€7193-7507 or €1838/year) and was higher in those taking strong versus weak opioids; €9886 (€9608-10,164, €2472/year) vs. €5519 (€5349-5689, €1380/year), p < 0.001. Analgesia cost (16.0% of total cost, 70.2% opioids) was higher with strong versus weak opioids, 19.6% vs. 11.3%, p < 0.001. CONCLUSIONS: In routine clinical practice in Spain, patients with moderate-to-severe chronic OA pain refractory to standard analgesic treatment with NSAIDs plus opioids reported modest reductions in pain, while presenting a considerable burden of comorbidities, cognitive impairment, and dependency. Healthcare costs significantly increased for the NHS particularly with NSAIDs plus strong opioids.
