Medication Related Self- efficacy among Linguistically Diverse Patients with Chronic Illnesses.

This study examines medication-related self-efficacy in a linguistically diverse group of patients with diabetes, hypertension, and elevated cholesterol. A telephone survey of 509 adults conducted in six languages (English, Spanish, Korean, Vietnamese, Mandarin, and Cantonese) was analyzed. Self-efficacy was assessed with the overall Medication Understanding and Use Self-Efficacy (MUSE) score and its two subscale scores on taking medication and learning about medications. Compared with English proficient (EP) patients, patients with limited English proficiency (LEP) had a lower mean learning self-efficacy subscale score (LEP: 14.5, EP: 15.4; p<.001) and no difference in the mean taking self-efficacy subscale score (LEP: 14.4, EP: 14.6; p=.40). Receiving verbal medication information (VMI) from providers modified the relationship between LEP status and learning self-efficacy. In conclusion, among patients with chronic illnesses, LEP patients had lower medication-related self-efficacy scores than EP patients, which may put them at greater risk for medication taking errors and lower adherence.

Outreach and Reminders to Improve Human Papillomavirus Vaccination in an Integrated Primary Care System.

This study evaluated the impact of health system-based outreach and reminders on human papillomavirus (HPV) vaccine series initiation and completion. Parents of 10 to 12 year olds (n = 1805) were randomized to receive either (1) an outreach letter and brochure recommending HPV vaccination followed by automated HPV vaccine reminders or (2) usual care. We interviewed a subset of 50 parents to assess program acceptability. Outcomes were HPV vaccine initiation during the study period and on-time series completion. Rates of HPV vaccine initiation during the study period (July 2015 to August 2016) were similar between the intervention and control groups, but initiation within 120 days of randomization was higher in the intervention group (23.6% and 18.8%, P = .04) as was completion during the study period (10.3% vs 6.8%, P = .04). Reminders for doses 2 and 3 did not affect completion. The program was acceptable to parents. This study provides evidence that health system-based outreach and reminders can improve HPV vaccination.

Development and Validation of the EXPECT Questionnaire: Assessing Patient Expectations of Outcomes of Complementary and Alternative Medicine Treatments for Chronic Pain.

BACKGROUND: Patient expectations may be associated with outcomes of complementary and alternative medicine (CAM) treatments for chronic pain. However, a psychometrically sound measure of such expectations is needed. OBJECTIVES: The purpose of this study was to develop and evaluate a questionnaire to assess individuals' expectations regarding outcomes of CAM treatments for chronic low back pain (CLBP), as well as a short form of the questionnaire. METHODS: An 18-item draft questionnaire was developed through literature review, cognitive interviews with individuals with CLBP, CAM practitioners, and expert consultation. Two samples completed the questionnaire: (1) a community sample (n = 141) completed it via an online survey before or soon after starting a CAM treatment for CLBP, and (2) participants (n = 181) in randomized clinical trials evaluating CAM treatments for CLBP or fibromyalgia completed it prior to or shortly after starting treatment. Factor structure, internal consistency, test-retest reliability, and criterion validity were examined. RESULTS: Based on factor analyses, 10 items reflecting expectations (used to create a total score) and three items reflecting hopes (not scored) were selected for the questionnaire. The questionnaire had high internal consistency, moderate test-retest reliability, and moderate correlations with other measures of expectations. A three-item short form also had adequate reliability and validity. CONCLUSIONS: The Expectations for Complementary and Alternative Medicine Treatments (EXPECT) questionnaire can be used in research to assess individuals' expectations of treatments for chronic pain. It is recommended that the three hope questions are included (but not scored) to help respondents distinguish between hopes and expectations. The short form may be appropriate for clinical settings and when expectation measurement is not a primary focus.

Disparities in the Use of Internet and Telephone Medication Refills among Linguistically Diverse Patients.

BACKGROUND: Health systems are increasingly implementing remote telephone and Internet refill systems to enhance patient access to medication refills. Remote refill systems may provide an effective approach for improving medication non-adherence, but more research is needed among patients with limited English proficiency with poor access to remote refill systems. OBJECTIVE: To compare the use of remote medication refill systems among limited-English-proficiency (LEP) and English-proficient (EP) patients with chronic conditions. METHODS: Cross-sectional survey in six languages/dialects (English, Cantonese, Mandarin, Korean, Vietnamese, and Spanish) of 509 adults with diabetes, hypertension, or hyperlipidemia. Primary study outcomes were self-reported use of 1) Internet refills, 2) telephone refills, and 3) any remote refill system. LEP was measured by patient self-identification of a primary language other than English and a claims record of use of an interpreter. Other measures were age, gender, education, years in the U.S., insurance, health status, chronic conditions, and number of prescribed medications. Analyses included multivariable logistic regression weighted for survey non-response. RESULTS: Overall, 33.1 % of patients refilled their medications by telephone and 31.6 % by Internet. Among LEP patients (n = 328), 31.5 % refilled by telephone and 21.2 % by Internet, compared with 36.7 % by telephone and 52.7 % by Internet among EP patients (n = 181). Internet refill by language groups were as follows: English (52.7 %), Cantonese (34.9 %), Mandarin (17.4 %), Korean (16.7 %), Vietnamese (24.4 %), and Spanish (12.6 %). Compared to EP patients, LEP patients had lower use of any remote refill system (adjusted odds ratio [AOR] 0.18; p < 0.001), CONCLUSIONS: LEP patients are significantly less likely than EP patients to use any remote medication refill system. Increased reliance on current systems for remote medication refills may increase disparities in health outcomes affecting LEP patients with poor access to telephone and Internet medication refills.

Linking mothers and infants within electronic health records: a comparison of deterministic and probabilistic algorithms.

PURPOSE: To compare probabilistic and deterministic algorithms for linking mothers and infants within electronic health records (EHRs) to support pregnancy outcomes research. METHODS: The study population was women enrolled in Group Health (Washington State, USA) delivering a liveborn infant from 2001 through 2008 (N = 33,093 deliveries) and infant members born in these years. We linked women to infants by surname, address, and dates of birth and delivery using deterministic and probabilistic algorithms. In a subset previously linked using "gold standard" identifiers (N = 14,449), we assessed each approach's sensitivity and positive predictive value (PPV). For deliveries with no "gold standard" linkage (N = 18,644), we compared the algorithms' linkage proportions. We repeated our analyses in an independent test set of deliveries from 2009 through 2013. We reviewed medical records to validate a sample of pairs apparently linked by one algorithm but not the other (N = 51 or 1.4% of discordant pairs). RESULTS: In the 2001-2008 "gold standard" population, the probabilistic algorithm's sensitivity was 84.1% (95% CI, 83.5-84.7) and PPV 99.3% (99.1-99.4), while the deterministic algorithm had sensitivity 74.5% (73.8-75.2) and PPV 95.7% (95.4-96.0). In the test set, the probabilistic algorithm again had higher sensitivity and PPV. For deliveries in 2001-2008 with no "gold standard" linkage, the probabilistic algorithm found matched infants for 58.3% and the deterministic algorithm, 52.8%. On medical record review, 100% of linked pairs appeared valid. CONCLUSIONS: A probabilistic algorithm improved linkage proportion and accuracy compared to a deterministic algorithm. Better linkage methods can increase the value of EHRs for pregnancy outcomes research.
