Telephone-based motivational interviewing for medication adherence: a systematic review

ABSTRACTAdherence to prescribed medications continues to be a problem in the treatment of chronic disease. Motivational interviewing (MI) has been shown to be successful for eliciting patients’ motivations to change their medication-taking behaviors. Due to the constraints of the US healthcare system, patients do not always have in-person access to providers. Because of this, there is increasing use of non-traditional healthcare delivery methods such as telephonic counseling. A systematic review was conducted among published studies of telephone-based MI interventions aimed at improving the health behavior change target of medication adherence. The goals of this review were to (1) examine and describe evidence and gaps in the literature for telephonically delivered MI interventions for medication adherence and (2) discuss the implications of the findings for research and practice. The MEDLINE, CINAHL, psycINFO, psycARTICLES, Academic Search Premier, Alt HealthWatch, Health Source: Consumer Edition, and Health Source: Nursing/Academic Edition databases were searched for peer-reviewed research publications between 1991 and October 2012. A total of nine articles were retained for review. The quality of the studies and the interventions varied significantly, which precluded making definitive conclusions but findings among a majority of retained studies suggest that telephone-based MI may help improve medication adherence. The included studies provided promising results and justification for continued exploration in the provision of MI via telephone encounters. Future research is needed to address gaps in the current literature but the results suggest that MI may be an efficient option for healthcare professionals seeking an evidence-based method to reach remote or inaccessible patients to help them improve their medication adherence.

Parental acceptance of human papillomavirus vaccinations and community pharmacies as vaccination settings: A qualitative study in Alabama

Purpose To determine parents’ knowledge and attitudes regarding human papillomavirus (HPV) vaccinations in their adolescent children and to describe parents’ perceptions of adolescent vaccinations in community pharmacies. Methods In-depth interviews were completed with parents or guardians of children ages 11–17 years from Alabamas Lee and Macon counties. One-hour long, open-ended telephonic or in-person interviews were conducted until the saturation point was reached. Using ATLAS.ti software and thematic analysis, interview transcripts were coded to identify themes. Results Twenty-six parents were interviewed, most of whom were female (80.8%) and white (50%). A total of 12 themes were identified. First, two themes emerged regarding elements facilitating childrens HPV vaccination, the most common being positive perception of the HPV vaccine. Second, elements hindering childrens vaccination contained seven themes, the top one being lack of correct or complete information about the HPV vaccine. The last topic involved acceptance/rejection of community pharmacies as vaccination settings, and the most frequently cited theme was concern about pharmacists’ clinical training. Conclusions Physician-to-parent vaccine education is important, and assurances of adequate pharmacy immunization training will ease parents’ fears and allow pharmacists to better serve adolescents, especially those who do not see physicians regularly.

Pharmacists’ Attitudes and Perceived Barriers to Human Papillomavirus (HPV) Vaccination Services

Use of non-traditional settings such as community pharmacies has been suggested to increase human papillomavirus (HPV) vaccination uptake and completion rates. The objectives of this study were to explore HPV vaccination services and strategies employed by pharmacies to increase HPV vaccine uptake, pharmacists’ attitudes towards the HPV vaccine, and pharmacists’ perceived barriers to providing HPV vaccination services in community pharmacies. A pre-piloted mail survey was sent to 350 randomly selected community pharmacies in Alabama in 2014. Measures included types of vaccines administered and marketing/recommendation strategies, pharmacists’ attitudes towards the HPV vaccine, and perceived system and parental barriers. Data analysis largely took the form of descriptive statistics. 154 pharmacists completed the survey (response rate = 44%). The majority believed vaccination is the best protection against cervical cancer (85.3%), HPV is a serious threat to health for girls (78.8%) and boys (55.6%), and children should not wait until they are sexually active to be vaccinated (80.1%). Perceived system barriers included insufficient patient demand (56.5%), insurance plans not covering vaccination cost (54.8%), and vaccine expiration before use (54.1%). Respondents also perceived parents to have inadequate education and understanding about HPV infection (86.6%) and vaccine safety (78.7%). Pharmacists have positive perceptions regarding the HPV vaccine. Barriers related to system factors and perceived parental concerns must be overcome to increase pharmacist involvement in HPV vaccinations.

Exploration of heterogeneity in distributed research network drug safety analyses

Distributed data networks representing large diverse populations are an expanding focus of drug safety research. However, interpreting results is difficult when treatment effect estimates vary across datasets (i.e., heterogeneity). In a previous study, risk estimates were generated for selected drugs and potential adverse outcomes. Analyses were replicated across eight distributed data sources using an identical analytic structure. To evaluate heterogeneity of risk estimates across data sources, the estimates were combined with summary-level data characterizing the population of each data source. Meta-analysis, meta-regression, and plots of the influence on overall results versus contribution to heterogeneity were examined and used to illustrate an approach to heterogeneity assessment. Heterogeneity, as measured by the I-squared statistic, was high with variability across outcomes. Plots of the relationship between influence on overall results and contribution to heterogeneity suggest that certain datasets and characteristics were influential but there was variability dependent on the drug and outcome being assessed. Exploratory meta-regression identified many possible influential factors, but may be subject to ecological bias and false positive conclusions. Distributed data network drug safety analyses can produce heterogeneous risk estimates that may not be easily explained. Approaches illustrated here can be useful for research that is subject to similar problems with heterogeneity.
