Descriptive study of homeless patients' perceptions that affect medication adherence

A systematic review of approaches to improve medication adherence in homeless adults with psychiatric disorders

Introduction

Medication non-adherence is a significant problem among homeless individuals with psychiatric disorders in the United States. We conducted a systematic review to identify strategies to improve psychiatric medication adherence among homeless individuals with psychiatric disorders, including substance use disorders.

Methods

We searched seven databases (MEDLINE, Embase, PsychInfo, Scopus, Web of Science, CDSR, and CENTRAL) and screened 664 studies by title and abstract followed by full-text review. Our inclusion criteria were studies that: involved an intervention for homeless adults with psychiatric disorders, reported a quantitative outcome of medication adherence, and were published in English in a peer-reviewed journal. We rated the relative effectiveness of strategies described in each study using a self-designed scale.

Results

Eleven peer-reviewed studies met criteria for inclusion in this review. Within these studies, there were seven different approaches to improve medication adherence in this population. Three studies were randomized controlled trials (RCTs) and the remaining were observational studies. Outpatient interventions included Assertive Community Treatment, Cell Phone-Assisted Monitoring, Customized Adherence Enhancement plus Long-Acting Injectable Medications, and Homeless-Designated Pharmacy Clinics. Residential, shelter-based, and inpatient interventions included use of the Housing First model, Modified Therapeutic Communities, and Homeless-Designated Inpatient Care. The approaches described in four of the eleven studies were rated as scoring a 3 or higher on a 5-point scale of effectiveness in improving medication adherence; none received 5 points.

Discussion

The interventions with the strongest evidence for improving medication adherence in this population were Assertive Community Treatment, Customized Adherence Enhancement plus Long-Acting Injectable Medications, and Housing First. Overall, studies on this topic required more rigor and focus on medication adherence as an outcome in this population. This review highlights several promising strategies and the need for larger RCTs to determine effective and diverse ways to improve medication adherence among homeless adults with psychiatric disorders.

Inpatients' information needs about medication: A narrative systematic literature review

OBJECTIVE

To provide an overview of inpatients' information needs about medication, including the best moment to provide this information, how, by whom and what patient characteristics influence these needs.

METHODS

A systematic literature review was conducted. Studies that reported the information needs from inpatients about medication were included from Medline and Embase. The Crowe critical appraisal tool (CCAT) was used to assess the quality of the studies.

RESULTS

Initially, 710 records were retrieved from Medline and Embase. After the forward search, another 609 records were screened and in total, 26 articles were included. The CCAT scores ranged from 17 to 34 points on a 40 point scale and two articles received 0 points.

CONCLUSION

Inpatients main needs about medicine information are information about adverse and beneficial effects of medication, and general rules about how to take medication. Preferably, this information is printed and provided at the time of prescribing by a physician that already has a relationship with the patient. The most recent studies show that patients are open to the use of modern technology.

PRACTICE IMPLICATIONS

This review provides a starting point for providing medicine information to inpatients. Further research should focus on patient characteristics influencing these information needs.

Non-adherence to psychiatric medication in adults experiencing homelessness is associated with incurred concussions

This study investigated the relationship between concussions and medication adherence among 247 adults experiencing homelessness in Oklahoma City, Oklahoma, who were prescribed medication for a psychiatric disorder. Participants were asked whether they had “ever experienced a blow to the head that caused a concussion,” and medication adherence was measured by asking participants whether they had taken their psychiatric medication yesterday. The data were analyzed using univariate and multivariable logistic regressions. Results showed that more than half of the sample had a concussion history (61.9%), and homeless adults with a concussion history had higher odds of non-adherence to psychiatric medications compared with those who reported no concussion history [OR = 2.13 (95% CI = 1.08, 4.18)]. Findings suggest that medication non-adherence is associated with incurred concussions. Raising awareness among service providers of the relationship between traumatic brain injury and medication adherence may increase efforts to improve adherence in this underserved population.
