Similarities and differences between asthma health care professional and patient views regarding medication adherence.

ABSTRACT: The recent literature has reported disparate views between patients and health care professionals regarding the roles of various factors affecting medication adherence.To examine the perspectives of asthma patients, physicians and allied health professionals regarding adherence to asthma medication.A qualitative, multiple, collective case study design with six focus-group interviews including 38 participants (13 asthma patients, 13 pulmonologist physicians and 12 allied health professionals involved in treating asthma patients) was conducted.Patients, physicians and allied health professionals understood adherence to be an active process. In addition, all participants believed they had a role in treatment adherence, and agreed that the cost of medication was high and that access to the health care system was restricted. Major disagreements regarding patient-related barriers to medication adherence were identified among the groups. For example, all groups referred to side effects; however, while patients expressed their legitimate concerns, health care professionals believed that patients' opinions of medication side effects were based on inadequate perceptions.Differences regarding medication adherence and barriers to adherence among the groups examined in the present study will provide insight into how disagreements may be translated to overcome barriers to optimal asthma adherence. Furthermore, when designing an intervention to enhance medication adherence, it is important to acknowledge that perceptual gaps exist and must be addressed.

Project description:To date, several medication adherence instruments have been developed and validated worldwide. However, most instruments have only assessed medication adherence from the patient's perspective. The aim was to develop and validate the PATIENT-Medication Adherence Instrument (P-MAI) and the HEALTHCARE PROFESSIONAL-Medication Adherence Instrument (H-MAI) to assess medication adherence from the patient's and healthcare professional (HCP)'s perspectives. The P-MAI-12 and H-MAI-12 were developed using the nominal group technique. The face and content validity was determined by an expert panel and piloted. The initial version of these instruments consisted of 12 items were validated from October-December 2018 at a primary care clinic in Malaysia. Included were patients aged ≥21 years, diagnosed with diabetes mellitus, taking at least one oral hypoglycaemic agent and who could understand English. The HCPs recruited were family medicine specialists or trainees. To assess validity, exploratory factor analysis (EFA) and concurrent validity were performed; internal consistency and test-retest were performed to assess its reliability. A total of 120/158 patients (response rate = 75.9%) and 30/33 HCPs (response rate = 90.9%) agreed to participate. EFA found three problematic items in both instruments, which was then removed. The final version of the P-MAI-9 and the HMAI-9 had 9 items each with two domains (adherence = 2 items and knowledge/belief = 7 items). For concurrent validity, the total score of the P-MAI-9 and the H-MAI-9 were not significantly different (p = 0.091), indicating that medication adherence assessed from both the patient's and HCP's perspectives were similar. Both instruments achieved acceptable internal consistency (Cronbach's α: P-MAI-9 = 0.722; H-MAI-9 = 0.895). For the P-MAI-9, 7/9 items showed no significant difference between test and retest whereas 8/9 items in the H-MAI-9 showed significant difference at test and retest (p>0.05). In conclusion, the P-MAI-9 and H-MAI-9 had low sensitivity and high specificity suggesting that both instruments can be used for identifying patients more likely to be non-adherent to their medications.

Project description:Background and Purpose- We assessed ethnic differences in medication adherence 3 months poststroke in a population-based study as an initial step in investigating the increased stroke recurrence risk in Mexican Americans compared with non-Hispanic whites. Methods- Ischemic stroke cases from 2008 to 2015 from the Brain Attack Surveillance in Corpus Christi project in Texas were followed prospectively for 3 months poststroke to assess medication adherence. Medications in 5 drug classes were analyzed: statins, antiplatelets, anticoagulants, antihypertensives, and antidepressants. For each drug class, patients were considered adherent if they reported never missing a dose in a typical week. The χ2 tests or Kruskal-Wallis nonparametric tests were used for ethnic comparisons of demographics, risk factors, and medication adherence. A multivariable logistic regression model was constructed for the association of ethnicity and medication nonadherence. Results- Mexican Americans (n=692) were younger (median 65 years versus 68 years, P<0.001), had more diabetes mellitus ( P<0.001) and hypertension ( P<0.001) and less atrial fibrillation ( P=0.003), smoking ( P=0.003), and education ( P<0.001) than non-Hispanic whites (n=422). Sex, insurance status, high cholesterol, previous stroke/transient ischemic attack history, excessive alcohol use, tPA (tissue-type plasminogen activator) treatment, National Institutes of Health Stroke Scale score, and comorbidity index did not significantly differ by ethnicity. There was no significant difference in medication adherence for any of the 5 drug classes between Mexican Americans and non-Hispanic whites. Conclusions- This study did not find ethnic differences in medication adherence, thus challenging this patient-level factor as an explanation for stroke recurrence disparities. Other reasons for the excessive stroke recurrence burden in Mexican Americans, including provider and health system factors, should be explored.

Project description:BackgroundEmpirical research and health policies on asthma have focused on children and young adults, even though asthma morbidity and mortality are higher among older asthmatics.ObjectiveTo explore the relationship of asthma-related beliefs and self-reported controller medication adherence in older asthmatics.DesignAn observational study of asthma beliefs and self-management among older adults.ParticipantsAsthmatics ages ? 60 years (N?=?324, mean age 67.4 ± 6.8, 28 % white, 32 % black, 30 % Hispanic) were recruited from primary care practices in New York City and Chicago.Main measuresSelf-reported controller medication adherence was assessed using the Medication Adherence Report Scale. Based on the Common Sense Model of Self-Regulation, patients were asked if they believe they only have asthma with symptoms, their physician can cure their asthma, and if their asthma will persist. Beliefs on the benefit, necessity and concerns of treatment use were also assessed. Multivariate logistic regression was used to examine the association of beliefs with self-reported medication adherence.Key resultsThe majority (57.0 %) of patients reported poor adherence. Poor self-reported adherence was more common among those with erroneous beliefs about asthma illness and treatments, including the "no symptoms, no asthma" belief (58.7 % vs. 31.7 %, respectively, p?<?0.001), "will not always have asthma" belief (34.8 % vs. 12.5 %, p?<?0.001), and the "MD can cure asthma" belief (21.7 % vs. 9.6 %, p?=?0.01). Adjusting for illness beliefs, treatment beliefs and demographics, patients with a "no symptoms, no asthma" belief had lower odds of having good self-reported adherence (odds ratio [OR] 0.45, 95 % confidence interval [CI] 0.23-0.86), as did those with negative beliefs about the benefits (OR 0.73, 95 % CI 0.57-0.94) and necessity (OR 0.89, 95 % CI 0.83-0.96) of treatment.ConclusionsIllness and treatment beliefs have a strong influence on self-reported medication adherence in older asthmatics. Interventions to improve medication adherence in older asthmatics by modifying illness and treatment beliefs warrant study.
