Improving delirium care: prevention, monitoring, and assessment.

Delirium is an acute change in awareness and attention and is common, morbid, and costly for patients and health care systems. While hyperactive delirium is easily identifiable, the hypoactive form is more common and carries a higher mortality. Hospital systems to address delirium should consist of 3 critical steps. First, hospitals must identify patients who develop or are at intermediate or high risk for delirium. Delirium risk may be assessed using known patient-based and illness-based risk factors, including preexisting cognitive impairment. Delirium diagnosis remains a clinical diagnosis that requires a clinical assessment that can be structured using diagnostic criteria. Hospital systems may be useful to efficiently allocate delirium resources to prevent and manage delirium. Second, it is crucial to develop a systematic approach to prevent delirium using multimodal nonpharmacologic delirium prevention methods and to monitor all high-risk patients for its occurrence. Tools such as the modified Richmond Agitation and Sedation Scale can aid in monitoring for changes in mental status that could indicate the development of delirium. Third, hospital systems can utilize established methods to assess and manage delirium in a standardized fashion. The key lies in addressing the underlying cause/causes of delirium, which often involve medical conditions or medications. With a sustained commitment, standardized efforts to identify and prevent delirium can mitigate the long-term morbidity associated with this acute change. In the face of changes in health care funding, delirium serves as an example of a syndrome where care coordination can improve short-term and long-term costs.

Complexity perplexity: a systematic review to describe the measurement of medication regimen complexity.

INTRODUCTION: Complex medication regimens are error prone and challenging for patients, which may impact medication adherence and safety. No universal method to assess the complexity of medication regimens (CMRx) exists. The authors aim to review literature for CMRx measurements to establish consistencies and, secondarily, describe CMRx impact on healthcare outcomes. AREAS COVERED: A search of EMBASE and PubMed for studies analyzing at least two medications and complexity components, among those self-managing medications, was conducted. Out of 1204 abstracts, 38 studies were included in the final sample. The majority (74%) of studies used one of five validated CMRx scales; their components and scoring were compared. EXPERT OPINION: Universal CMRx assessment is needed to identify and reduce complex regimens, and, thus, improve safety. The authors highlight commonalities among five scales to help build consensus. Common components (i.e., regimen factors) included dosing frequency, units per dose, and non-oral routes. Elements (e.g., twice daily) of these components (e.g., dosing frequency) and scoring varied. Patient-specific factors (e.g., dexterity, cognition) were not addressed, which is a shortcoming of current scales and a challenge for future scales. As CMRx has important outcomes, notably adherence and healthcare utilization, a standardized tool has potential for far-reaching clinical, research, and patient-safety impact.

Aging, antiretrovirals, and adherence: a meta analysis of adherence among older HIV-infected individuals.

INTRODUCTION: Older adults are generally considered to be at greater risk for medication non-adherence due to factors such as medication complexity, side effects, cost, and cognitive decline. However, this generalization may not apply to older adults with human immunodeficiency virus (HIV). Regardless of age, suboptimal adherence to antiretroviral therapy (ART) can lead to increased viral load, immunosuppression, drug-resistant viral strains, co-morbidities, and opportunistic infections. Understanding trends of adherence to ART among older adults is critical, especially as the population of people living with HIV grows older. OBJECTIVES: The purpose of this systematic review and meta-analysis is to determine if older individuals with HIV are less likely to be non-adherent to antiretroviral therapy than younger individuals with HIV. DESIGN: A systematic search in PubMed, Embase, and PsycINFO was conducted to identify peer-reviewed articles evaluating adherence to ART in older adults. Two independent reviewers screened abstracts, applied inclusion criteria, and appraised study quality. The bibliographies of qualifying studies were searched. Data were abstracted from studies by two independent authors. Meta-analyses were conducted, and adherence levels were reported as the relative risk of non-adherence in older individuals compared to younger individuals. RESULTS: The systematic search yielded 1,848 abstracts. Twelve studies met full inclusion criteria. The overall meta-analysis found that older age reduced risk for nonadherence by 27 % (relative risk (RR) 0.72, 95 % confidence interval (CI) 0.64­0.82). Studies assessing both short-term and long-term adherence demonstrated a significant reduction in non-adherence among older patients (RR 0.75, 95 % CI 0.64­0.87 and RR 0.65, 95 % CI 0.50­0.85, respectively). CONCLUSIONS: Older adults with HIV have a reduced risk for non-adherence to ART than their younger counterparts. Future studies should seek to elucidate contributing factors of adherence among older individuals with HIV.

The use of a video interview to enhance gross anatomy students' understanding of professionalism.

There is much room for innovation in teaching medical students professionalism. The goal of this exercise was to enhance first-year Gross Anatomy students' understanding of professionalism, including the attributes of confidentiality, respectful behavior and humanism in medicine through a video interview with a donor family member. Survey results demonstrated that students generally agreed that the video helped them better understand professionalism in the context of the gross anatomy laboratory and gave them a deeper respect for donors. Most students strongly agreed that future medical students would benefit from viewing this video interview.
