Background: Hip fracture trials have employed a wide range of patient-reported outcomes (PRO) suggesting a lack of consensus among clinicians on what are considered the most relevant outcomes. Variability in functional outcome reporting in hip fracture management creates challenges in the comparison of results across trials. The purpose of this study was to conduct a systematic review of the functional outcomes fielded in randomized controlled trials in post-operative hip fracture treatment for the aged. We hypothesized that over time there had been an increase in patient-reported outcomes along with aggregate scoring systems of hip function.

Methods: An electronic database search was conducted using key terms combining: ‘hip fracture’ with ‘RCT’ with ‘age 65 years and over’. s and titles were screened in duplicate and independently. All of the articles that met eligibility criteria were reviewed using the 21-point Detsky Quality Assessment Scale.

Results: In 2451 citations, 86 studies were included and also met accepted standards of inter-observer reliability (kappa, 0.92; 95% confidence interval, 0.87 to 0.98). The mean score (and standard error) for the quality of the randomized trials was: 75.8% ± 1.76% (95% confidence interval, 72.3%–79.3%) and 27 (32.6%) of the trials scored < 75%. Medical trials had a higher mean quality score than did surgical trials (83.7% compared with 72.7 %, p = 0.025). 59 trials (30 Surgical, 11 medical and 18 rehabilitation trials) scored > 75% in quality. Out of 86 trials, 8 (13.6%) used EQ-5D for utility and 6 (10.1%) used the SF-36 health status measures. At most, 12 trials used the same composite score: 12 (13.9%) ADL Katz Index, 9 (10.4%) trials used the HHS and 8 (9.3%) trials used Parker’s mobility score.

Conclusion: Although in the past decade more studies have made use of outcome instruments that capture both impairment and functional status in one aggregate score, there is a lack of standardized assessment.

Background: The literature on hip fractures is increasingly reporting patient-reported outcomes along with aggregate scoring systems. However, this rapid growth in the number and types of patient-based outcomes can be confusing. The purpose of this paper is to conduct a systematic review of the functional outcome instruments fielded in high quality randomized clinical trials evaluating postoperative hip fracture management and rehabilitation in the aged.

Methods: An electronic database search was conducted using a variety of key terms combining: ‘hip fracture’ with ‘RCT’ with ‘age 65 years and over’. Abstracts and titles were screened in duplicate and independently. Studies were eligible based on the following criteria: hip fracture, randomized controlled trial, mean age of 65 years, and in the English language. Studies were excluded based on the following criteria: inclusion of fractures other than hip, minimum age of patient enrolment < 50 years old and prevention or fracture risk reduction as primary outcome of study. All of the articles that met eligibility criteria were reviewed using the Detsky Quality Assessment Scale.

Results: In 2451 citations, 86 studies were included and also met accepted standards of inter-observer reliability (kappa, 0.92; 95% confidence interval, 0.87 to 0.98). Discordance was resolved by consensus. The mean score (and standard error) for the quality of the randomized trials was: 75.8% ± 1.76% (95% confidence interval, 72.3%–79.3%) and 27 (32.6%) of the trials scored < 75%. Medical trials had a higher mean quality score than did surgical trials (83.7% compared with 72.7 %, p = 0.025). Data was abstracted from the 59 trials (30 Surgical, 11 medical and 18 rehabilitation trials) scoring > 75% in quality. Surgical trials had 16.7% more measures of disability than measures of impairment. Furthermore, 70% of the surgical trials used composite scores when compared to either medical or rehabilitation trials. Eight trials (13.6%) used EQ-5D for utility and 6 (10.1%) used the SF-36 health status measures. At most, 10 trials used the same composite score: 10 (16,9%) ADL Katz Index, 9 (15.2%) trials used the Harris hip score and 5 (8.5%) trials used Parker’s mobility score.

Discussion/Conclusion: Although there is a trend towards studies assessing functional recovery as a primary outcome in the aged with hip fractures, none of the measures were used consistently. A lack of standardized assessment in these groups of patients will overestimate treatment effects.
