The association of race, gender, and comorbidity with mortality and function after hip fracture.

Background: Few studies of hip fracture have large enough samples of men, minorities, and persons with specific comorbidities to examine differences in their mortality and functional outcomes. To address this problem, we combined three cohorts of hip fracture patients to produce a sample of 2692 patients followed for 6 months.

Method: Data on mortality, mobility, and other activities of daily living (ADLs) were available from all three cohorts.

Heterogeneity in hip fracture patients: age, functional status, and comorbidity.

Objectives: To examine unidentified heterogeneity in hip fracture patients that may predict variation in functional outcomes.

Design: Observational, longitudinal, multisite cohort study.

Setting: Three separate cohorts from five hospitals in the metropolitan New York area and eight hospitals in Baltimore.

Effect of inpatient quality of care on functional outcomes in patients with hip fracture.

Objectives: We sought to examine the relationship between functional outcome and process of care for patients with hip fracture.

Research Design And Participants: We undertook a prospective cohort study in 4 hospitals of 554 patients treated with surgery for hip fracture.

Measurements: Information on patient characteristics and processes of hospital care collected from the medical record, interviews, and bedside observations.

Patient relocation in the 6 months after hip fracture: risk factors for fragmented care.

Objectives: To describe the incidence and patterns of patient relocation after hip fracture, identify factors associated with relocation, and examine effect of relocation on outcomes.

Design: Prospective cohort study.

Setting: Four hospitals in the New York metropolitan area.

The effect of perioperative anemia on clinical and functional outcomes in patients with hip fracture.

Objectives: To describe the epidemiology of perioperative anemia in patients with hip fracture and assess the relationship between the hemoglobin measurements and clinical outcomes.

Design: Prospective observational cohort study.

Setting: Four university and community teaching hospitals.

Physical therapy and mobility 2 and 6 months after hip fracture.

Objectives: To examine the relationship between early physical therapy (PT), later therapy, and mobility 2 and 6 months after hip fracture.

Design: Prospective, multisite observational study.

Setting: Four hospitals in the New York City area.

Association of timing of surgery for hip fracture and patient outcomes.

Context: Previous studies of surgical timing in patients with hip fracture have yielded conflicting findings on mortality and have not focused on functional outcomes.

Objective: To examine the association of timing of surgical repair of hip fracture with function and other outcomes.

Design: Prospective cohort study including analyses matching cases of early (< or =24 hours) and late (>24 hours) surgery with propensity scores and excluding patients who might not be candidates for early surgery.

Effects of blood transfusion on clinical and functional outcomes in patients with hip fracture.

Background: Anemia and transfusion are common among elderly patients requiring surgery. The effects of transfusion on morbidity and mortality are controversial. The influence of transfusion on risk-adjusted mortality, readmissions, and functional mobility was examined.

The impact of post-operative pain on outcomes following hip fracture.

Untreated pain is a major health care issue and very little is known about the treatment of pain and the effect of pain on post-operative outcomes in older adults. This study was performed to identify the impact of pain on outcomes following hip fracture in older adults. Four hundred and eleven consecutive cognitively intact patients admitted with hip fracture to four New York hospitals were enrolled in a prospective cohort study.

Hospital readmissions after hospital discharge for hip fracture: surgical and nonsurgical causes and effect on outcomes.

Objectives: To examine the causes of hospital readmission after hip fracture and the relationships between hospital readmission and 6-month physical function and mortality.

Design: Prospective, multisite, observational cohort study.

Setting: Four hospitals in the New York City metropolitan area.

Frequency and impact of active clinical issues and new impairments on hospital discharge in patients with hip fracture.

Background: Hip fracture is associated with significant mortality and disability. Patients who are discharged from the hospital with active clinical problems may have worse outcomes than those patients without active clinical problems.

Objective: To assess the frequency and impact of clinical problems at discharge on clinical and functional hip fracture outcomes.

Patients with hip fracture: subgroups and their outcomes.

Objectives: To present several alternative approaches to describing the range and functional outcomes of patients with hip fracture.

Design: Prospective study with concurrent medical records data collection and patient and proxy interviews at the time of hospitalization and 6 months later.

Setting: Four hospitals in the New York metropolitan area.
