Conventional research methods, including randomized controlled trials, are powerful techniques for determining the efficacy of interventions. These designs, however, have practical limitations when applied to many rehabilitation settings and research questions. Alternative methods are available that can supplement findings from traditional research designs and improve our ability to evaluate the effectiveness of treatments for individual patients. The focus on individual patients is an important element of evidenced-based rehabilitation. This article examines one such alternate approach: small-N research designs. Small-N designs usually focus on 10 or fewer participants whose behavior (outcomes) are measured repeatedly and compared over time. The advantages and limitations of various small-N designs are described and illustrated using 3 examples from the rehabilitation literature. The challenges and opportunities of applying small-N designs to enhance evidence-based rehabilitation are discussed.

Making the Case for Patient-Reported Outcome Measures in Big-Data Rehabilitation Research: Implications for Optimizing Patient-Centered Care

Tamra Keeney, Amit Kumar, Kimberly S. Etter, Amol M. Karmarkar

Summary: Advancements in data science and health informatics have opened up possibilities for integrating patient-reported outcome measures (PROMs) into clinical workflows and improving rehabilitation service delivery. Standardization of PROMs data collection and increased partnerships can help advance rehabilitation health services research.

Factors associated with post-acute functional status and discharge dispositions in individuals with spinal cord injury

Shivayogi V. Hiremath, Amol M. Karmarkar, Amit Kumar, Donna L. Coffman, Ralph J. Marino

Summary: This study examined the association between demographic, clinical, and process of care factors with post-acute functional status and discharge disposition in individuals with SCI, finding that certain factors such as age, length of stay, injury severity, and type of injury had significant impacts on functional outcomes and discharge destination in these patients. Further research is needed to determine the national variations in these associations in order to inform trauma and acute care post-SCI.

Shifting US Patterns of COVID-19 Mortality by Race and Ethnicity From June-December 2020

Amit Kumar, Indrakshi Roy, Amol M. Karmarkar, Kimberly S. Erler, James L. Rudolph, Julie A. Baldwin, Maricruz Rivera-Hernandez

Summary: This study found significant disparities in COVID-19-related mortality rates for nursing homes serving minority residents during the first 12 weeks of the study period. As time progressed, these differences changed, highlighting the need for policy interventions and equitable distribution of vaccines to mitigate the impact of systemic racial injustice on the health outcomes of people of color residing in nursing homes.

Associations of Multiple Chronic Conditions With Physical Performance and Falls Among Older Adults With Back Pain: A Longitudinal, Population-based Study

Sean D. Rundell, Amol Karmarkar, Michael Nash, Kushang V. Patel

Summary: The study found that older adults with back pain who have multiple chronic conditions, especially arthritis, depression, and anxiety, are associated with poor physical functioning and an increased risk of falls over time.

Economic impact of comorbid TBI-dementia on VA facility and non-VA facility costs, 2000-2020

Clara E. Dismuke-Greer, Aryan Esmaeili, Amol M. Karmarkar, Boyd Davis, Carla Garcia, Mary Jo Pugh, Kristine Yaffe

Summary: A study compared the costs associated with Traumatic Brain Injury (TBI) and dementia, finding that the main cost driver was inpatient care costs in non-VA facilities. Veterans had continuously increasing inpatient care costs in non-VA facilities over time.

Clinical features of dementia cases ascertained by ICD coding in LIMBIC-CENC multicenter study of mild traumatic brain injury

William C. Walker, Justin O'Rourke, Elisabeth Anne Wilde, Mary Jo Pugh, Kimbra Kenney, Clara Libby Dismuke-Greer, Zhining Ou, Angela P. Presson, J. Kent Werner, Jacob Kean, Deborah Barnes, Amol Karmarkar, Kristine Yaffe, David Cifu

Summary: This study investigated the presence of dementia cases identified through ICD coding in a multicenter prospective longitudinal study of mild traumatic brain injury in military veterans. The findings suggest a potential link between blast-related mTBI, PTSD, and early dementia, although the specificity of the ICD codes needs to be considered.

Medicare Claim-Based National Institutes of Health Stroke Scale to Predict 30-Day Mortality and Hospital Readmission

Amit Kumar, Indrakshi Roy, Pamela R. Bosch, Corey R. Fehnel, Nicholas Garnica, Jon Cook, Meghan Warren, Amol M. Karmarkar

Summary: This study is a retrospective cohort study of 43,241 Medicare beneficiaries with ischemic stroke, aiming to examine the predictive ability of claim-based NIHSS for 30-day mortality and readmission rates. The NIHSS was found to be significantly associated with 30-day mortality and exhibited stronger discriminant property compared to the Elixhauser comorbidity index.

Impact of Hospital-Based Rehabilitation Services on Discharge to the Community by Value-Based Payment Programs After Joint Replacement Surgery

Amit Kumar, Indrakshi Roy, Meghan Warren, Stefany D. Shaibi, Maximilian Fabricant, Jason R. Falvey, Amit Vashist, Amol M. Karmarkar

Summary: The study examines the impact of hospital-based rehabilitation services on community discharge rates after hip and knee replacement surgery. The findings suggest that higher amounts of rehabilitation services are associated with a higher likelihood of discharge to the community.

Healthcare utilization and costs among high-need and frail Mexican American Medicare beneficiaries

Maricruz Rivera-Hernandez, Amit Kumar, Lin-Na Chou, Tamra Keeney, Nasim Ferdows, Amol Karmarkar, Kyriakos S. Markides, Kenneth Ottenbacher

Summary: This study examines Medicare health care spending and health services utilization among high-need population segments in older Mexican Americans, and explores the impact of frailty on health care spending and utilization. The findings highlight that participants with major complex chronic illnesses who are also pre-frail or frail have higher total costs and utilization compared to the healthy segment.
