Dataset Information

Declining daily functioning as a prelude to a hip fracture in older persons-an individual patient data meta-analysis.

ABSTRACT:

Background

Daily functioning is known to decline after a hip fracture, but studies of self-reported functioning before the fracture suggest this decline begins before the fracture.

Objective

Determine whether change in functioning in the year before a hip fracture in very old (80+) differs from change in those without a hip fracture.

Design

Two-stage individual patient data meta-analysis including data from the Towards Understanding Longitudinal International older People Studies (TULIPS)-consortium.

Setting

Four population-based longitudinal cohorts from the Netherlands, New Zealand and the UK.

Subjects

Participants aged 80+ years.

Methods

Participants were followed for 5 years, during which (instrumental) activities of daily living [(I)ADL] scores and incident hip fractures were registered at regular intervals. Z-scores of the last (I)ADL score and the change in (I)ADL in the year before a hip fracture were compared to the scores of controls, adjusted for age and sex.

Results

Of the 2,357 participants at baseline, the 161 who sustained a hip fracture during follow-up had a worse (I)ADL score before the fracture (0.40 standard deviations, 95% CI 0.19 to 0.61, P = 0.0002) and a larger decline in (I)ADL in the year before fracture (-0.11 standard deviations, 95% CI -0.22 to 0.004, P = 0.06) compared to those who did not sustain a hip fracture.

Conclusions

In the very old a decline in daily functioning already starts before a hip fracture. Therefore, a hip fracture is a sign of ongoing decline and what full recovery is should be seen in light of the pre-fracture decline.

Project description:BackgroundA Rehabilitation Program for older adults with hip fracture (HIP-REP) based on Activity of Daily Living has been developed. The objectives of this study were to assess the feasibility and safety of the HIP-REP program to inform a future randomized controlled trial (RCT).MethodsA feasibility study Inspired by the Complex-intervention development (Medical Research Council framework phase II) design using quantitative and qualitative research methods were conducted. Eighteen participants (above 65 years) with hip fracture were recruited from the orthopedic wards. The setting was cross sectoral including Copenhagen University Hospital, Herlev and Gentofte and rehabilitation centers in Herlev, Gentofte and Lyngby-Taarbæk municipalities. A cross-sectoral rehabilitation intervention tailored to the needs of older adults with hip fracture highlighting systematic goal setting and strategies focused on activities of daily living was conducted. Pre-defined feasibility criteria: participants recruitment and retention, duration of measuring the outcome, adherence to intervention, and adverse events, along with self-reported outcomes and an objective measurement of performance in activity of daily living. Focus groups were analyzed using a deductive manifest content analysis approach. Descriptive statistical analysis and paired t-tests were performed for assessing change in outcome measures.ResultsRecruitment rate was 4.5/month. Outcome measures were performed but length and number of questionnaires were a burden. Thirteen out of eighteen participants completed the study three dropped out and two died. Adherence among the 13 was 100%. Focus group revealed issues regarding coordinating the intervention, ensuring procedural processes across sectors regarding recruitment of participants, and documentation in the database. Participants expressed satisfaction with the intervention and felt safe during intervention. Assessment of Motor and Process Skills showed better increase between (range 0.4 to 1.6) in ADL motor ability measures and better increase between (range 0.4 to 0.7) for process ability. No clear association between outcome improvements and intervention adherence.ConclusionsThe cross-sectoral intervention based on daily activities was feasible and safe for older adults with hip fracture. A future RCT, with an improved recruitment strategy and reduced number of outcome measures will evaluate the effectiveness in improving independence and safety performance of activity of daily living.Trial registrationClinicalTrials.gov ID: NCT03828240 .

Project description:ObjectivesDefining common patterns of recovery after an acute health stressor (resiliency groups) has both clinical and research implications. We sought to identify groups of patients with similar recovery patterns across 10 outcomes following hip fracture (stressor) and to determine the most important predictors of resiliency group membership.DesignSecondary analysis of three prospective cohort studies.SettingParticipants were recruited from various hospitals in the Baltimore Hip Studies network and followed for up to 1 year in their residence (home or facility).ParticipantsCommunity-dwelling adults aged 65 years or older with recent surgical repair of a hip fracture (n = 541).MeasurementsSelf-reported physical function and activity measures using validated scales were collected at baseline (within 15-22 d of fracture), 2, 6, and 12 months. Physical performance tests were administered at all follow-up visits. Stressor characteristics, comorbidities, and psychosocial and environmental factors were collected at baseline via participant report and chart abstraction. Latent class profile analysis was used to identify resiliency groups based on recovery trajectories across 10 outcome measures and logistic regression models to identify factors associated with those groups.ResultsLatent profile analysis identified three resiliency groups that had similar patterns across the 10 outcome measures and were defined as "high resilience" (n = 163 [30.1%]), "medium resilience" (n = 242 [44.7%]), and "low resilience" (n = 136 [25.2%]). Recovery trajectories for the outcome measures are presented for each resiliency group. Comparing highest with the medium- and low-resilience groups, self-reported pre-fracture function was by far the strongest predictor of high-resilience group membership with area under the curve (AUC) of .84. Demographic factors, comorbidities, stressor characteristics, environmental factors, and psychosocial characteristics were less predictive, but several factors remained significant in a multivariable model (AUC = .88).ConclusionThese three resiliency groups following hip fracture may be useful for understanding mediators of physical resilience. They may provide a more detailed description of recovery patterns in multiple outcomes for use in clinical decision making. J Am Geriatr Soc 67:2519-2527, 2019.
