Selecting a change and evaluating its impact on the performance of a complex adaptive health care delivery system

Complexity science suggests that our current health care delivery system acts as a complex adaptive system (CAS). Such systems represent a dynamic and flexible network of individuals who can coevolve with their ever changing environment. The CAS performance fluctuates and its members’ interactions continuously change over time in response to the stress generated by its surrounding environment. This paper will review the challenges of intervening and introducing a planned change into a complex adaptive health care delivery system. We explore the role of the “reflective adaptive process” in developing delivery interventions and suggest different evaluation methodologies to study the impact of such interventions on the performance of the entire system. We finally describe the implementation of a new program, the Aging Brain Care Medical Home as a case study of our proposed evaluation process

Alzheimer’s disease multiple intervention trial (ADMIT): study protocol for a randomized controlled clinical trial

Abstract Background Given the current lack of disease-modifying therapies, it is important to explore new models of longitudinal care for older adults with dementia that focus on improving quality of life and delaying functional decline. In a previous clinical trial, we demonstrated that collaborative care for Alzheimer’s disease reduces patients’ neuropsychiatric symptoms as well as caregiver stress. However, these improvements in quality of life were not associated with delays in subjects’ functional decline. Trial design Parallel randomized controlled clinical trial with 1:1 allocation. Participants A total of 180 community-dwelling patients aged ≥45 years who are diagnosed with possible or probable Alzheimer’s disease; subjects must also have a caregiver willing to participate in the study and be willing to accept home visits. Subjects and their caregivers are enrolled from the primary care and geriatric medicine practices of an urban public health system serving Indianapolis, Indiana, USA. Interventions All patients receive best practices primary care including collaborative care by a dementia care manager over two years; this best practices primary care program represents the local adaptation and implementation of our prior collaborative care intervention in the urban public health system. Intervention patients also receive in-home occupational therapy delivered in twenty-four sessions over two years in addition to best practices primary care. The focus of the occupational therapy intervention is delaying functional decline and helping both subjects and caregivers adapt to functional impairments. The in-home sessions are tailored to the specific needs and goals of each patient-caregiver dyad; these needs are expected to change over the course of the study. Objective To determine whether best practices primary care plus home-based occupational therapy delays functional decline among patients with Alzheimer’s disease compared to subjects treated in the control group. Outcomes The primary outcome is the Alzheimer’s Disease Cooperative Studies Group Activities of Daily Living Scale; secondary outcome measures are two performance-based measures including the Short Physical Performance Battery and Short Portable Sarcopenia Measure. Outcome assessments for both the caregiver-reported scale and subjects’ physical performance scales are completed in the subject’s home. Randomization Eligible patient-care giver dyads will be stratified by clinic type and block randomized with a computer developed randomization scheme using a 1:1 allocation ratio. Blinding Single blinded. Research assistants completing the outcome assessments were blinded to the subjects’ treatment group. Trial status Ongoing ClinicalTrial.Gov identifier NCT01314950; date of completed registration 10 March 2011; date first patient randomized 9 March 2011</p

Health Policy Advancing social and economic development by investing in women&apos;s and children&apos;s health: a new Global Investment Framework

A new Global Investment Framework for Women&apos;s and Children&apos;s Health demonstrates how investment in women&apos;s and children&apos;s health will secure high health, social, and economic returns. We costed health systems strengthening and six investment packages for: maternal and newborn health, child health, immunisation, family planning, HIV/ AIDS, and malaria. Nutrition is a cross-cutting theme. We then used simulation modelling to estimate the health and socioeconomic returns of these investments. Increasing health expenditure by just $5 per person per year up to 2035 in 74 high-burden countries could yield up to nine times that value in economic and social benefi ts. These returns include greater gross domestic product (GDP) growth through improved productivity, and prevention of the needless deaths of 147 million children, 32 million stillbirths, and 5 million women by 2035. These gains could be achieved by an additional investment of$30 billion per year, equivalent to a 2% increase above current spending

Disparity in posttraumatic stress disorder diagnosis among African American pregnant women

To determine whether African American women expecting their first infant carry a disproportionate burden of posttraumatic stress disorder morbidity, we conducted a comparative analysis of cross-sectional data from the initial psychiatric interview in a prospective cohort study of posttraumatic stress disorder effects on childbearing outcomes. Participants were recruited from maternity clinics in three health systems in the Midwestern USA. Eligibility criteria were being 18 years or older, able to speak English, expecting a first infant, and less than 28 weeks gestation. Telephone interview data was collected from 1,581 women prior to 28 weeks gestation; four declined to answer racial identity items (n =1,577), 709 women self-identified as African American, 868 women did not. Measures included the Life Stressor Checklist, the National Women’s Study Posttraumatic Stress Disorder Module, the Composite International Diagnostic Interview, and the Centers for Disease Control’s Perinatal Risk Assessment Monitoring System survey. The 709 African American pregnant women had more trauma exposure, posttraumatic stress disorder symptoms and diagnosis, comorbidity and pregnancy substance use, and had less mental health treatment than 868 non-African Americans. Lifetime prevalence was 24.0% versus 17.1%, respectively (OR=1.5, p=0.001). Current prevalence was 13.4% versus 3.5% (OR=4.3, p< 0.001). Current prevalence of posttraumatic stress disorder (PTSD) was four times higher among African American women. Their risk for PTSD did not differ by sociodemographic status, but was explained by greater trauma exposure. Traumatic stress may be an additional, addressable stress factor in birth outcome disparities
