Language-concordant automated telephone queries to assess medication adherence in a diverse population: a cross-sectional analysis of convergent validity with pharmacy claims.

ABSTRACT: BACKGROUND:Clinicians have difficulty accurately assessing medication non-adherence within chronic disease care settings. Health information technology (HIT) could offer novel tools to assess medication adherence in diverse populations outside of usual health care settings. In a multilingual urban safety net population, we examined the validity of assessing adherence using automated telephone self-management (ATSM) queries, when compared with non-adherence using continuous medication gap (CMG) on pharmacy claims. We hypothesized that patients reporting greater days of missed pills to ATSM queries would have higher rates of non-adherence as measured by CMG, and that ATSM adherence assessments would perform as well as structured interview assessments. METHODS:As part of an ATSM-facilitated diabetes self-management program, low-income health plan members typed numeric responses to rotating weekly ATSM queries: "In the last 7 days, how many days did you MISS taking your …" diabetes, blood pressure, or cholesterol pill. Research assistants asked similar questions in computer-assisted structured telephone interviews. We measured continuous medication gap (CMG) by claims over 12 preceding months. To evaluate convergent validity, we compared rates of optimal adherence (CMG???20%) across respondents reporting 0, 1, and???2 missed pill days on ATSM and on structured interview. RESULTS:Among 210 participants, 46% had limited health literacy, 57% spoke Cantonese, and 19% Spanish. ATSM respondents reported ?1 missed day for diabetes (33%), blood pressure (19%), and cholesterol (36%) pills. Interview respondents reported ?1 missed day for diabetes (28%), blood pressure (21%), and cholesterol (26%) pills. Optimal adherence rates by CMG were lower among ATSM respondents reporting more missed days for blood pressure (p?=?0.02) and cholesterol (p?

Project description:BACKGROUND:Since the adoption of United Nations' Sustainable Goal 4.2 to ensure that all children have access to quality early child development (ECD) so that they are ready for primary education, the demand for valid ECD assessments has increased in contexts where they do not yet exist. The development of early language ability is important for school readiness. Our objective was to evaluate the validity of a method to develop vocabulary checklists in new languages to assess early language development, based on the MacArthur-Bates Communicative Development Inventories. METHODS:Through asking mothers of young children what words their children say and through pilot testing, we developed 100-word vocabulary checklists in multilingual contexts in Malawi and Ghana. In Malawi, we evaluated the validity of the vocabulary checklist among 29 children age 17-25 months compared to three language measures assessed concurrently: Developmental Milestones Checklist-II (DMC-II) language scale, Malawi Developmental Assessment Tool (MDAT) language scale, and the number of different words (NDW) in 30-min recordings of spontaneous speech. In Ghana, we assessed the predictive validity of the vocabulary checklist at age 18 months to forecast language, pre-academic, and other skills at age 4-6 years among 869 children. We also compared the predictive validity of the vocabulary checklist scores to that of other developmental assessments administered at age 18 months. RESULTS:In Malawi, the Spearman's correlation of the vocabulary checklist score with DMC-II language was 0.46 (p = 0.049), with MDAT language was 0.66 (p = 0.016) and with NDW was 0.50 (p = 0.033). In Ghana, the 18-month vocabulary checklist score showed the strongest (rho = 0.12-0.26) and most consistent (8/12) associations with preschool scores, compared to the other 18-month assessments. The largest coefficients were the correlations of the 18-month vocabulary score with the preschool cognitive factor score (rho = 0.26), language score (0.25), and pre-academic score (0.24). CONCLUSIONS:We have demonstrated the validity of a method to develop vocabulary checklists in new languages, which can be used in multilingual contexts, using a feasible adaptation process requiring about 2 weeks. This is a promising method to assess early language development, which is associated with later preschool language, cognitive, and pre-academic skills.

Project description:BackgroundLanguage concordance can increase access to care for patients with language barriers and improve patient health outcomes. However, systematically assessing and tracking physician non-English language skills remains uncommon in most health systems. This is a missed opportunity for health systems to maximize language-concordant care.ObjectiveTo determine barriers and facilitators to participation in non-English language proficiency assessment among primary care physicians.DesignQualitative, semi-structured interviews.ParticipantsEleven fully and partially bilingual primary care physicians from a large academic health system with a language certification program (using a clinician oral proficiency interview).ApproachInterviews aimed to identify barriers and facilitators to participation in non-English language assessment. Two researchers independently and iteratively coded transcripts using a thematic analysis approach with constant comparison to identify themes.Key resultsMost participants were women (N= 9; 82%). Participants reported proficiency in Cantonese, Mandarin, Russian, and Spanish. All fully bilingual participants (n=5) had passed the language assessment; of the partially bilingual participants (n=6), four did not test, one passed with marginal proficiency, and one did not pass. Three themes emerged as barriers to assessment participation: (1) beliefs about the negative consequences (emotional and material) of not passing the test, (2) time constraints and competing demands, and (3) challenging test format and structure. Four themes emerged as facilitators to increase assessment adoption: (1) messaging consistent with professional ethos, (2) organizational culture that incentivizes certification, (3) personal empowerment about language proficiency, and (4) individuals championing certification.ConclusionsTo increase language assessment participation and thus ensure quality language-concordant care, health systems must address the identified barriers physicians experience and leverage potential facilitators. Findings can inform health system interventions to standardize the requirements and process, increase transparency, provide resources for preparation and remediation, utilize messaging focused on patient care quality and safety, and incentivize participation.

Project description:BackgroundThe health risks associated with poor medication practices in the home suggest that patients would benefit from home-based medication reviews that could detect and resolve these issues. However, remuneration for home visits often excludes ambulatory, nonhomebound patients. A subset of these patients have issues that cannot be adequately identified and resolved during the course of a typical pharmacy-based medication review.PurposeThis study aims to characterize the prevalence and nature of "hidden in the home" medication management issues in nonhomebound patients.MethodsPharmacists facilitated subject enrollment among patients at 6 community pharmacies in Toronto over a 15-month period, from January 2016 to March 2017. Patients taking 5 or more chronic medications who were ambulatory (able to visit the pharmacy) and scored 3 points or higher on a prescreening questionnaire were invited to participate. Visits included a standard medication review, the identification of drug therapy problems and an assessment of the patient's medication and organization/storage practices, followed by a medication cabinet cleanup.ResultsOne hundred patients were recruited, with a mean age of 76.9 years and taking on average 10 chronic medications. Pharmacists identified a total of 275 drug therapy problems (2.75 per patient). The most common issues reported additional therapy required (23.6%), nonadherence (23.3%) and adverse drug reactions (17.8%). For those patients 65 years or older (87%), 32% were found to be using at least 1 medication on the Beers Criteria list, while 6% were using 3 or more. Sulfonylureas, non-steroidal anti-inflammatory drugs and short-acting benzodiazepines were the most commonly implicated drugs. Medications were removed from the homes of 67% of the patients, with expiry of medication being the most common reason for removal (54.2%). The mean duration of a home visit was 49.5 minutes.ConclusionPharmacist-directed home medication reviews offer an effective mechanism to address the pharmacotherapy issues of patients taking multiple medications. These findings highlight the frequency of medication management issues in this group and suggest that home medication reviews could serve to minimize inappropriate use of medication and maximize health care cost savings in this unique patient population.
