Summary View help for Summary
The Boston Rehabilitative Impairment Study of the Elderly (Boston RISE) was a prospective cohort study of older primary care patients, aged 65 years and older, who were at risk for declining mobility and disability at baseline. The study was designed to investigate which combinations of neuromuscular impairments are most responsible for mobility decline and disability over 2 years of follow up.

Study Design View help for Study Design
The study visits were designed to collect extensive information on medical and rehabilitative impairments according to the aims of the study. An effort was made to evaluate all relevant attributes while also keeping subject burden manageable. During the first baseline visit, a nurse practitioner and a research assistant obtained informed consent and conducted the final eligibility screening. If the participant screened into the study, the nurse practitioner conducted the baseline visit, which generally required 2.5 hours including informed consent. This assessment included a physical examination, medical history, medication inventory, demographics, neuropsychological testing, and questionnaires on pain. The second baseline visit, which was conducted by a research assistant, took place within 2 weeks of the first visit and generally required 2 hours. This assessment included physical performance testing and questionnaires on functional ability, falls, rehabilitative care, and physical activity. Participants received $20 for each baseline visit. Transportation to both visits using commercial wheelchair-accessible vans was provided for all participants as needed. Follow-up assessments were conducted at 12 and 24 months at Spaulding Rehabilitation Hospital Cambridge and used the same 2-visit structure. Between each set of visits, study staff contacted participants by phone every 3 months for a brief interview tracking falls, hospitalizations, emergency department visits, and rehabilitative care. Recruitment was initiated in December 2009 and was completed in January 2012.
Sample View help for Sample
Study recruitment targeted adults aged 65 years or older living within a 10-mile radius from and who were receiving primary care at Massachusetts General Hospital (MGH) or Brigham and Women's Hospital (BWH). Study staff used the Research Patient Data Registry (RPDR) to generate primary care provider specific lists of patients meeting the preliminary eligibility criteria. The RPDR is a centralized clinical data registry housing clinical information from Partners HealthCare facilities. Patients meeting the preliminary inclusion criteria within a provider's panel were randomly selected for inclusion on the recruitment master list. The master list was divided into subgroups based on sex, age, and race, and sorted into a random order to ensure random selection from each subgroup. Screening samples of 50 to 100 patients were created and sent to each provider for review. Oversampling did occur within the sample lists with regard to race, age, and sex to ensure recruitment of a cohort representative of the older adult population living within the recruitment catchment area. The providers received the screening sample by e-mail and were asked to respond within 1 week to corroborate eligibility. Study staff sent a reminder e-mail to nonresponding providers after 1 week. Participating practices were given posters and brochures to display in waiting areas so interested patients could contact study staff directly.
Potential participants approved for contact were sent either a single letter signed by the provider and the principal investigator (for MGH patients) or 2 letters signed separately by the provider and the principal investigator (for BWH patients). The letters described the study and included a postage-paid postcard to return to decline participation. The letters stated that study staff would try to contact patients by phone if there was no response within 2 weeks. Study staff made up to 7 attempts to reach potential participants by phone.
During the initial phone contact, study staff performed an eligibility screening. To be included, participants had to (1) be age 65 or older (2) be able to understand and communicate in English and (3) have difficulty or task modification with walking one-half mile (6 blocks) or climbing 1 flight (10 steps) of stairs. Study staff also asked questions to determine the presence of major medical problems that would interfere with safe completion of the study protocol: significant visual impairment, uncontrolled hypertension, lower extremity amputation, supplemental oxygen use, and myocardial infarction or major surgery in the previous 6 months. Study participation was limited to English speakers because it was not feasible to translate the study instruments and conduct the interviews in the many other languages spoken in the Boston area.
Individuals who expressed interest in participating and met eligibility criteria were scheduled for the 2 baseline visits. Final eligibility was determined at the first visit. Researchers excluded persons with a Mini-Mental State Exam score of less than 18, which indicated moderate or severe cognitive impairment. Researchers also excluded persons scoring less than 4 on the Short Physical Performance Battery (SPPB), which indicated existing disability. To ensure a broad distribution of baseline physical functioning, researchers used the SPPB score to group prospective enrollees based on mobility performance. Researchers excluded individuals scoring 11 or 12 (maximum score) on the SPPB once the preselected threshold was reached.

Description of Variables View help for Description of Variables
There are four datasets in the collection:
Dataset 1 (Main Data File) contains 1,290 cases and 247 variables. The data file includes demographic variables such as education, marital status, and gender. There are scores derived from administered instruments such as the Mini Mental State Exam (MMSE), the Short Physical Performance Battery (SPPB), and the Hopkins Verbal Learning Test (HVLT). There are several variables asking respondents if they have certain health problems such as heart disease, hypertension, or lung disease. Respondents were also asked about their history of smoking and falls. Pain was measured using the Brief Pain Inventory (BPI) and the McGill Pain Map. Additionally, scores derived from the Late Life Function and Disability Instrument (LLFDI) and the Patient Health Questionnaire (PHQ-9) are included. Lastly, there are measures of physical ability and characteristic scores such as range of motion, coordination, endurance, and body mass index (BMI).
Dataset 2 (Falls and Rehabilitation Follow-Up) contains 4,273 cases and 13 variables. The variables pertain to recent falls, hospital stays, rehabilitative care, and emergency room vists.
Dataset 3 (Medications) contains 10,293 cases and 9 variables. The variables relate to medications taken by respondents such as name, strength, route, and number taken. There are also variables for the Iowa Drug Information Service drug name and number.
Dataset 4 (Tracking) contains 430 cases and 7 variables. The variables include the participant's status at Years 1 to 4 and provides a reason if the participant missed a visit or left the study.
Response Rates View help for Response Rates
Of 7,403 primary patients identified using the Research Patient Data Registry (RPDR), 5,333 (72 percent) were approved by primary care providers to receive communication about the study. Recruitment letters were received by 4,495 people and 47 people independently contacted study staff after seeing recruitment materials in primary care offices or hearing about the study from a family member or friend. Among 1,349 people who had phone screenings, 712 (56 percent) met eligibility for the final screening at the clinic study site. Informed consent was given by 523 people, and 443 (85 percent) met eligibility criteria for continuation in the study. Out of those, 430 (96 percent) completed both baseline visits.
