Background Recent interventions to improve transitions in care for older adults focus on hospital discharge processes. Limited data exists on patient concerns for care at home after discharge, particularly for vulnerable older adults. Design We used in-depth, in-person interviews to describe barriers to recovery at home after leaving the hospital for vulnerable, older adults. We purposefully sampled by age, gender, race, and English proficiency to ensure a wide breadth of experiences. Interviews were independently coded by two investigators using the constant comparative method. Thematic analysis was performed by the entire research team with diverse backgrounds in primary care, hospital medicine, geriatrics, and nursing. Setting and Participants We interviewed vulnerable older adults (low income/health literacy, and/or Limited English Proficiency) who were enrolled in a larger discharge interventional study within 30 days of discharge from an urban public hospital. All participants were interviewed in their native language (English, Spanish, or Chinese). Results We interviewed 24 patients: mean age 63 (55–84), 66% male, 67% Non-white, 16% Spanish-speaking, 16% Chinese-speaking. We identified an overarching theme of “missing pieces” in the plan for post-discharge recovery at home from which three specific sub-themes emerged: (1) functional limitations and difficulty with mobility and self-care tasks; (2) social isolation and lack of support from family and friends; (3) challenges from poverty and the built environment at home. In contrast, patients described mostly supportive experiences with traditional focuses of transition care such as following prescribed medication and diet regimens. Conclusion Hospital-based discharge interventions that focus on traditional aspects of care may overlook social and functional gaps in post-discharge care at home for vulnerable older adults. Post-discharge interventions that address these challenges may be necessary to reduce readmissions in this population.
Objective To determine in a 48-month longitudinal study the association of thigh muscle cross-sectional area (CSA) and strength on progression of morphologic knee cartilage degeneration using 3T magnetic resonance imaging (MRI). Design Seventy Osteoarthritis Initiative (OAI) subjects aged 50-60 years, with no radiographic evidence of osteoarthritis (OA) and constant muscle strength over 48 months as measured by isometric knee extension testing were included. Baseline right thigh muscle CSAs were assessed on axial T1-weighted MR images, and extensor to flexor CSA ratios were calculated. Degenerative knee abnormalities at baseline and 48-months were graded on right knee 3T MRIs using a modified whole organ MRI score (WORMS). Statistical analysis employed Student's t-tests and multivariable regression models adjusted for age, body mass index and gender. Results Extension strength was significantly and positively correlated with baseline thigh muscle CSA (r=0.65, p<0.001). Greater baseline total thigh muscle CSA was significant associated with increase of cartilage WORMS scores over 48 months in patellar (p=0.027) and trochlear (p=0.038) compartments, but not in other knee compartments. Among specific muscle groups, CSA of extensors (p=0.021) and vastus medialis (VM) (p=0.047) were associated with patellar cartilage increase in WORMS. Baseline E/F ratio had a significant positive association with patellar WORMS cartilage score increase over 48 months, p=0.0015. There were no other significant associations between muscle CSA/ratios and increase in WORMS scores. Conclusion Maintenance of proper extensor to flexor muscle balance about the knee through decreased E/F ratios may slow patellofemoral cartilage deterioration, while higher extensor and VM CSA may increase patellofemoral cartilage loss.
Background Compressive osseointegration is a promising modality for limb salvage in distal femoral oncologic tumors. However, few studies have explored short-term survival rates in a large patient cohort of distal femur compressive endoprostheses or highlighted the risk factors for spindle failures. Questions/purposes We asked: (1) prostheses were implanted for aggressive primary tumors of the distal femur and/or failure of previous oncologic reconstruction. This approach represented approximately 91% of the distal femoral reconstructions performed during that time. Of the patients with prostheses implanted, four patients (four of 116, 3%) had died, and 37 (37 of 116, 32%) were lost to followup before 24 months. The median followup was 84 months (range, 24-198 months), and 71 patients (66% of all patients) were seen within the last 3 years. A retrospective chart review was performed to determine failure modality as defined by radiographs, clinical history, and intraoperative findings. Risk factors including age, sex, BMI, resection length, and perioperative chemotherapy were analyzed to determine effect on spindle and rotational failure rates. Survival analysis was determined using the Kaplan-Meier estimator. Differences in survival between groups were analyzed using the log rank test. Risk factors were determined using Cox proportional hazard modeling.Each author certifies that he or she, or a member of his or her immediate family, has no funding or commercial associations (eg, consultancies, stock ownership, equity interest, patent/licensing arrangements, etc) that might pose a conflict of interest in connection with the submitted article. 123Clin Orthop Relat Res (2016) 474:1714-1723 DOI 10.1007 Clinical Orthopaedics and Related Research ® A Publication of The Association of Bone and Joint Surgeons®Results Spindle survival at 5 and 10 years was 91% (95% CI, 82%-95%). Survival rates from rotational failure at 5 and 10 years were 92% (95% CI, 83%-96%); the majority of failures occurred within the first 2 years postoperatively and were the result of a twisting mechanism of injury. With the numbers available, none of the potential risk factors examined were associated with mechanical failure. The 5-year and 10-year all-cause revision-free survival rates were 57% (95% CI, 44%-67%) and 50% (95% CI, 36%-61%), respectively. Conclusions Distal femur compressive osseointegration is a viable method for endoprosthetic reconstruction. Rotational failure is rare with the majority occurring early. No variables were found to correlate with increased risk of mechanical failure. More research is needed to evaluate methods of preventing mechanical and rotational failures in addition to other common causes of revision such as infection in these massive endoprosthetic reconstructions. Level of Evidence Level IV, therapeutic study.
