impact of pharmacist intervention on disease knowledge, rehabilitation and medication adherence, treatment induced direct cost, health-related quality of life and satisfaction in patients with rheumatoid arthritis

Conditions: Rheumatoid Arthritis

Summary: the objective of this study was to evaluate effectiveness of pharmacist intervention in improving disease knowledge, adherence to treatment, health related quality of life and direct cost of treatment. the study also documented patient satisfaction with pharmacist counselling as a quality control measure. this is a randomized controlled single-blind two-arm trial in patients with rheumatoid arthritis in karachi, pakistan. the study will enroll patients with established diagnosis of rheumatoid arthritis over three months. the patients after signing written consent would be randomized through a computer-generated list in control group, i.e., usual care and intervention group, i.e., pharmaceutical care with a ratio of 1:1. the study will take place in three patient-visits over the course of three months. the patients would be intervened by pharmacist in intervention group while those in control group will have usual care. primary outcomes include change in mean score at follow-up, i.e., week 12, for disease knowledge, adherence to medications and rehabilitation/physical therapy, health related quality of life (hrqol). the secondary outcomes include change in the mean direct cost of treatment and patient satisfaction from pharmacist counselling. this is a novel study that evaluates the role of pharmacist in improving treatment outcomes of patients with rheumatoid arthritis. the results of this trial could set the foundation for future delivery of care for such patients in pakistan. the results of this trial would be published in a peer-reviewed journal.

rheumatoid arthritis is a chronic inflammatory disease that mainly affects the joints and results in pain, swelling and decreased mobility. the disease over the course of time, leads to joint deformity and disability. the disease ranks third as major cause of disability after osteoarthritis and gout and affects roughly 1% of global population. decrease mobility in patients results in decreased productivity and further worsens their quality of life. while pharmacological treatment may be essential in managing the acute flares and episodic pain associated with the disease, self-care and home-based management of ra is another important area of care which patients need to incorporate to manage it effectively. several studies have reported that self-care in ra effectively reduces acute flares. this could be done through the use of patient education and counselling. pharmacist provide pharmaceutical care that incorporates these areas of care. pharmaceutical care is an individualized patient-centric health service delivered by pharmacists that incorporates, but is not limited to, disease education, therapy management, self-care and self-management of disease and therapy as well as motivational guidance. evidence from several randomized trials indicate that patient counselling, disease education and telephonic interventions have improved self-care practices of patients. educating patients about managing ra empowers them in understanding signs and symptoms of disease and devise ways to reduce or limit aggravating factors. a randomized trial conducted by petkova that involved community pharmacy-based patient education program improved treatment outcomes of arthritis patients. moreover, mary and colleagues demonstrated positive effect of mobile phone short message service on medication adherence of patients with ra. in the last decade there has been only few studies that have evaluated the impact of pharmacist-led pharmaceutical care on treatment outcomes in patients with rheumatoid arthritis. in pakistan, no study has been conducted till date that evaluates the same. since, the disease prevalence has increased in pakistani population of late, and mainly affects the middle-aged individuals, it is expected to affect their productivity, employ-ability and income. this would worsen their health-related quality of life and adds to economic burden of this disease on the society. therefore, a need was felt to evaluate the impact of pharmacist-delivered pharmaceutical care on treatment outcomes in pakistani patients with rheumatoid arthritis.
