Impact of a Swiss pressure ulcer prevention breakthrough collaborative.

RATIONALE, AIMS AND OBJECTIVES: Pressure ulcers may have severe impacts on the quality of life of patients, including pain, low mood and restrictions in performing daily life and social life activities. In Switzerland, 4% of patients develop hospital-acquired pressure ulcers. Six hospitals teamed up with the Vaud Hospital Federation (Switzerland) in a Breakthrough Collaborative, with the goal of reducing hospital-acquired pressure ulcers by 50%. The aim of this study was to assess the actual reduction. METHODS: A multimodal set of interventions was deployed in all wards except obstetrics and gynaecology, over 18 months starting in October 2016, including systematic risk assessment, use of a prevention bundle, education through e-learning, measurement and feedback, patient engagement and promotion of a safety culture. All six hospitals monitored compliance with the use of the risk assessment, bundle application and patient involvement aspects. A safety calendar was implemented in all wards, for recording and visually displaying the numbers of new patients with pressure ulcers, as well as the presence of such ulcers upon admission and their category. RESULTS: Compliance with performing Braden risk assessments rose from 39% at baseline to 61% by the end of the collaborative (P < .001), prevention bundle compliance from 2% to 30% (P < .001%) and documented patient engagement from 2% to 21% (P < .001%). The percentage of days where one or more patient was reported as having developed one or more pressure ulcers in the ward decreased from 8.21% to 4.18%, a 49% reduction (P < .001) which amounts to preventing 1124 new patients from developing one or more pressure ulcers during the collaborative. CONCLUSIONS: The Breakthrough Collaborative using a multimodal improvement approach combined with measurement and feedback was associated with a statistically and clinically significant improvement in compliance to best practice and with a reduction of hospital-acquired pressure ulcers by half.

Impact of TeamSTEPPS on patient safety culture in a Swiss maternity ward.

OBJECTIVE: To assess the impact of implementation of the TeamSTEPPS teamwork improvement concept on patient safety culture. DESIGN: Pre-post culture assessment using the Hospital Survey on Patient Safety Culture, at baseline and one year after implementation of TeamSTEPPS. SETTING: Two maternity wards within the same 480-bed multisite teaching hospital. INTERVENTION: Implementation of the TeamSTEPPS teamwork improvement concept. MAIN OUTCOME MEASURES: Analysis of variation of the percentage of positive responses (score) in both wards (intervention and control) was conducted. RESULTS: There was a significant increase in scores in three dimensions of patient safety culture in the intervention ward: Supervisor/Manager Expectations and Actions Promoting Safety increased from 48.7% in 2015 to 70.8% in 2016 (P < 0.005); Teamwork Within Units increased from 35.5% in 2015 to 54.5% in 2016 (P < 0.005); Nonpunitive Response to Errors increased from 16.7% in 2015 to 32.3% in 2016 (P < 0.005). Other dimensions showed no significant changes. In the control ward, there was a significant decrease in scores in one dimension. A secondary analysis of differences in differences still shows significant improvement in one dimension (Supervisor/Manager Expectations and Actions Promoting Safety P < 0.005). CONCLUSION: After implementing the TeamSTEPPS teamwork concept, patient safety culture significantly improved for three of twelve dimensions in the intervention group. When controlling for differences in baseline scores between implementation and control wards, a significant improvement remains in one dimension. This suggests that TeamSTEPPS could be considered when seeking to enhance patient safety culture, especially in high-risk environments such as maternity wards.

Are the Cumulated Ambulation Score and Risk Assessment and Prediction Tool useful for predicting discharge destination and length of stay following total knee arthroplasty?

BACKGROUND: Postoperative management of patients undergoing total knee arthroplasty (TKA) is continually changing. Costs related to TKA are driven by implant cost, operating room cost, hospital length of stay (LOS), and rehabilitation approach. Discharges to rehabilitation centers have declined significantly in recent years. AIM: We evaluated the usefulness of the Cumulated Ambulation Score (CAS) and Risk Assessment and Prediction Tool (RAPT) to predict discharge destination and estimate hospital LOS of patients undergoing TKA. DESIGN: Prospective cohort study. SETTING: University hospital inpatients. POPULATION: Patients undergoing elective primary TKA. METHODS: Consecutive patients were prospectively evaluated. Outcome measures were discharge destination and LOS dichotomized at the median (LOS<8 versus LOS≥8). Patients completed five outcome questionnaires and knee range of motion was measured preoperatively. RAPT was considered continuous, and also dichotomized (RAPT≤9 versus RAPT>9; RAPT9). CAS was dichotomized (CAS<11 versus CAS≥11; CAS11). Surgical technique and aftercare were similar for all patients. RESULTS: Sixty-four patients (37 females), mean age 69.3±10.2 years were evaluated. CAS11 and discharge destination were strongly associated: 75.9% of patients with CAS≥11 were discharged home; 85.7% of patients with CAS<11 were discharged to a rehabilitation center (P<0.001). 80.7% of patients with RAPT≤9 were discharged to a rehabilitation center, versus 36.4% of patients with RAPT>9 (P=0.002). Odds ratios for discharge home were 18.9 (CAS11) and 7.3 (RAPT). CAS11 and RAPT were not related to LOS. CONCLUSIONS: The CAS and RAPT can assist clinicians in estimating the discharge destination and developing patient care plans following TKA. However, predicting LOS with such tools alone was inaccurate. CLINICAL REHABILITATION IMPACT: Use of the CAS and RAPT can inform discharge destination and patient care plans following TKA and has the potential to optimise resources and costs. However, due to social and organizational constraints on discharge, predicting LOS with such tools alone revealed to be inaccurate.

Assessment of Avoidable Readmissions in a Visceral Surgery Department with an Algorithm: Methodology, Analysis and Measures for Improvement.

BACKGROUND: Standardized quality indicators assessing avoidable readmission become increasingly important in health care. They can identify improvements area and contribute to enhance the care delivered. However, the way of using them in practice was rarely described. METHODS: Retrospective study uses prospective inpatients' information. Thirty-day readmissions were deemed potentially avoidable or non-avoidable by a computerized algorithm, and annual rate was reported between 2010 and 2014. Observed rate was compared to expected rate, and medical record review of potentially avoidable readmissions was conducted on data between January and June 2014. RESULTS: During a period of ten semesters, 11,011 stays were screened by the algorithm and a potentially avoidable readmission rate (PAR) of 7% was measured. Despite stable expected rate of 5 ± 0.5%, an increase was noted concerning the observed rate since 2012, with a highest value of 9.4% during the first semester 2014. Medical chart review assessed the 109 patients screened positive for PAR during this period and measured a real rate of 7.8%. The delta was in part due to an underestimated case mix owing to sub-coded comorbidities and not to health care issue. CONCLUSIONS: The present study suggests a methodology for practical use of data, allowing a validated quality of care indicator. The trend of the observed PAR rate showed a clear increase, while the expected PAR rate was stable. The analysis emphasized the importance of adequate "coding chain" when such an algorithm is applied. Moreover, additional medical chart review is needed when results deviate from the norm.

Hand Hygiene Improvement and Sustainability: Assessing a Breakthrough Collaborative in Western Switzerland.

OBJECTIVE To assess hand hygiene improvement and sustainability associated with a Breakthrough Collaborative. DESIGN Multicenter analysis of hand hygiene compliance through direct observation by trained observers. SETTING A total of 5 publicly funded hospitals in 14 locations, with a total of 1,152 beds, in the County of Vaud, Switzerland. PARTICIPANTS Clinical staff. INTERVENTIONS In total, 59,272 opportunities for hand hygiene were monitored for the duration of the study, for an average of 5,921 per audit (range, 5,449-6,852). An 18-month Hand Hygiene Breakthrough Collaborative was conducted to implement the WHO multimodal promotional strategy including improved access to alcohol-based hand rub, education, performance measurement and feedback, reminders and communication, leadership engagement, and safety culture. RESULTS Overall hand hygiene compliance improved from 61.9% to 88.3% (P<.001) over 18 months and was sustained at 88.9% (P=.248) 12 months after the intervention. Hand hygiene compliance among physicians increased from 62% to 85% (P<.001) and finally 86% at follow-up (P=.492); for nursing staff, compliance improved from 64% to 90% (P<.001) and finally 90% at follow-up (P=.464); for physiotherapists compliance improved from 50% to 90% (P<.001) and finally 91% at follow-up (P=.619); for X-ray technicians compliance improved from 45% to 80% (P<.001) and finally 81% at follow-up (P=.686). Hand hygiene compliance also significantly increased with sustained improvement across all hand hygiene indications and all hospitals. CONCLUSIONS A rigorously conducted multicenter project combining the Breakthrough Collaborative method for its structure and the WHO multimodal strategy for content and measurement was associated with significant and substantial improvement in compliance across all professions, all hand hygiene indications, and all participating hospitals.

Prediction of potentially avoidable readmission risk in a division of general internal medicine.

INTRODUCTION: The 30-day post-discharge readmission rate is a quality indicator that may reflect suboptimal care. The computerised algorithm SQLape® can retrospectively identify a potentially avoidable readmission (PARA) with high sensitivity and specificity. We retrospectively analysed the hospital stays of patients readmitted to the Department of Internal Medicine of the CHUV (Centre Hospitalier Universitaire Vaudois) in order to quantify the proportion of PARAs and derive a risk prediction model. METHOD: All hospitalisations between January 2009 and December 2011 in our division of general internal medicine were analysed. Readmissions within 30 days of discharge were categorised using SQLape®. The impact on PARAs was tested for various clinical and nonclinical factors. The performance of the developed model was compared with the well-validated LACE and HOSPITAL scores. RESULTS: From a total of 11 074 hospital stays, 777 (7%) were followed with PARA within 30 days. By analysing a group of 6729 eligible stays, defined in particular by the patients' returning to their place of residence (home or residential care centre), we identified the following risk factors: ≥1 hospitalisation in the year preceding index admission, Charlson score >1, active cancer, hyponatraemia, length of stay >11 days, prescription of ≥15 different medications during the stay. These variables were used to derive a risk prediction model for PARA with a good discriminatory power (C-statistic 0.70) and calibration (p = 0.69). Patients were then classified as low (16.4%), intermediate (49.4%) or high (34.2%) risk of PARA. The estimated risk of PARA for each category was 3.5%, 8.7% and 19.6%, respectively. The LACE and the HOSPITAL scores were significantly correlated with the PARA risk. The discriminatory power of the LACE (C-statistic 0.61) and the HOSPITAL (C-statistic 0.54) were lower than our model. CONCLUSION: Our model identifies patients at high risk of 30-day PARA with a good performance. It could be used to target transition of care interventions. Nevertheless, this model should be validated on more data and could be improved with additional parameters. Our results highlight the difficulty to generalise one model in the context of different healthcare systems.

Heightened clinical utility of smartphone versus body-worn inertial system for shoulder function B-B score.

BACKGROUND: The B-B Score is a straightforward kinematic shoulder function score including only two movements (hand to the Back + lift hand as to change a Bulb) that demonstrated sound measurement properties for patients for various shoulder pathologies. However, the B-B Score results using a smartphone or a reference system have not yet been compared. Provided that the measurement properties are comparable, the use of a smartphone would offer substantial practical advantages. This study investigated the concurrent validity of a smartphone and a reference inertial system for the measurement of the kinematic shoulder function B-B Score. METHODS: Sixty-five patients with shoulder conditions (with rotator cuff conditions, adhesive capsulitis and proximal humerus fracture) and 20 healthy participants were evaluated using a smartphone and a reference inertial system. Measurements were performed twice, alternating between two evaluators. The B-B Score differences between groups, differences between devices, relationship between devices, intra- and inter-evaluator reproducibility were analysed. RESULTS: The smartphone mean scores (SD) were 94.1 (11.1) for controls and 54.1 (18.3) for patients (P < 0.01). The difference between devices was non-significant for the control (P = 0.16) and the patient group (P = 0.81). The analysis of the relationship between devices showed 0.97 ICC, -0.6 bias and -13.2 to 12.0 limits of agreement (LOA). The smartphone intra-evaluator ICC was 0.92, the bias 1.5 and the LOA -17.4 to 20.3. The smartphone inter-evaluator ICC was 0.92, the bias 1.5 and the LOA -16.9 to 20.0. CONCLUSIONS: The B-B Score results measured with a smartphone were comparable to those of an inertial system. While single measurements diverged in some cases, the intra- and inter-evaluator reproducibility was excellent and was equivalent between devices. The B-B score measured with a smartphone is straightforward and as efficient as a reference inertial system measurement.

Reliability of the Knee Smartphone-Application Goniometer in the Acute Orthopedic Setting.

The standard goniometer (SG) is the most commonly used tool to assess range of motion (ROM) in patients with knee restrictions. Several medical applications have been designed to measure joint ROM. Little data are available on their reliability in the postoperative clinical setting. The purpose of this study was to assess whether a smartphone accelerometer-based knee goniometer application (App) is as reliable as the SG to measure knee ROM in clinical settings. A total of 60 subjects were included in this cross-sectional reliability trial. Overall, 20 healthy subjects (HS) and 20 acute postoperative patients (PO) underwent three active and three passive measurements in knee flexion and extension, using the SG and the smartphone knee goniometer App. To determine the fatigability of postoperative patients, a third group of 20 patients underwent a single active measurement in knee flexion and extension (PO1). Measurements were performed by three clinicians. For intraobserver reliability, mean intraclass correlation coefficient (ICC) values were higher for the App in all circumstances (overall mean SG 0.85, App 0.91), indicating an excellent correlation. For interobserver reliability, the highest ICC scores were in the PO1 group, with the App more consistent than the SG in all movements. Interobserver reliability was lower in the PO group versus PO1. Interobserver reliability was better for active ROM than for passive measurements. The overall concordance coefficient was very good to excellent with active measurements (range, 0.60-0.97). In conclusion, the App is a reliable tool for use in acute orthopedic care and offers better intra- and interobserver correlation scores for a single active measurement.

Effect of Manual Lymphatic Drainage After Total Knee Arthroplasty: A Randomized Controlled Trial.

OBJECTIVE: To evaluate the effects of manual lymphatic drainage (MLD) on knee swelling and the assumed consequences of swelling after total knee arthroplasty (TKA). DESIGN: Randomized controlled trial. SETTING: Primary care hospital. PARTICIPANTS: Two groups of 30 patients were randomized before TKA surgery (N=60; 65% women [39]; mean age, 70.7±8.8y; weight, 77.8±11.3kg; size, 1.64±0.08m; body mass index, 29.9±4.1kg/m(2)). INTERVENTIONS: Participants received either 5 MLD treatments or a placebo, added to rehabilitation, in between the second day and the seventh day after surgery. MAIN OUTCOME MEASURES: Swelling was measured by blinded evaluators before surgery and at second day, seventh day, and 3 months using bioimpedance spectroscopy and volume measurement. Secondary outcomes were active and passive range of motion, pain, knee function, and gait parameters. RESULTS: At seventh day and 3 months, no outcome was significantly different between groups, except for the knee passive flexion contracture at 3 months, which was lower and less frequent in the MLD group (-2.6°; 95% confidence interval, -5.0° to -0.21°; P=.04; absolute risk reduction, 26.6%; 95% confidence interval, 0.9%-52.3%; number needed to treat, 4). The mean pain level decreased between 5.8 and 8.2mm on the visual analog scale immediately after MLD, which was significant after 4 of 5 MLD treatments. CONCLUSIONS: MLD treatments applied immediately after TKA surgery did not reduce swelling. It reduced pain immediately after the treatment. Further studies should investigate whether the positive effect of MLD on knee extension is replicable.

The impact of an enhanced recovery pathway on nursing workload: A retrospective cohort study.

BACKGROUND & AIMS: The importance of nursing for surgical patients has been frequently underestimated. The success of enhanced recovery programs after surgery (ERAS) depends on preferably complete fulfillment of the protocol and nurses are an important part of it. Due to the additional nursing action required, such protocols are suspected to increase the nursing workload. The aim of the present study was to observe and measure objectively nursing workload before, during and after systematic implementation of a comprehensive enhanced recovery pathway in colorectal surgery. METHODS: The program ERAS was introduced systematically in our tertiary academic centre 2011, since then our experience is based on more than 1500 ERAS patients. Nursing workload was prospectively assessed for all patients on a routine basis by means of a standardized and validated point system (PRN). In a retrospective cohort study, we compared nursing workload based on prospective data before, during and after ERAS implementation and correlated nursing workload to the compliance with the ERAS protocol. RESULTS: The study cohort included 50 patients before ERAS implementation (2010) and 69 (2011) and 148 (2012) consecutive patients after implementation; the baseline characteristics of the 3 groups were similar. Mean PRN values were 61.2 ± 19.7 per day in 2010 and decreased to 52.3 ± 13.7 (P = 0.005) and 51.6 ± 18.6 (P < 0.002) in 2011 and 2012, respectively. Increasing compliance with the ERAS protocol was significantly correlated to decreasing nursing workload (ρ = -0.42; P < 0.001). CONCLUSIONS: Nursing workload is--against a common belief--decreased by systematic implementation of enhance recovery protocol. The higher the compliance with the pathway, the lower the burden for the nurses!

Measurement properties of the smartphone-based B-B Score in current shoulder pathologies.

This study is aimed at the determination of the measurement properties of the shoulder function B-B Score measured with a smartphone. This score measures the symmetry between sides of a power-related metric for two selected movements, with 100% representing perfect symmetry. Twenty healthy participants, 20 patients with rotator cuff conditions, 23 with fractures, 22 with capsulitis, and 23 with shoulder instabilities were measured twice across a six-month interval using the B-B Score and shoulder function questionnaires. The discriminative power, responsiveness, diagnostic power, concurrent validity, minimal detectable change (MDC), minimal clinically important improvement (MCII), and patient acceptable symptom state (PASS) were evaluated. Significant differences with the control group and significant baseline-six-month differences were found for the rotator cuff condition, fracture, and capsulitis patient groups. The B-B Score was responsive and demonstrated excellent diagnostic power, except for shoulder instability. The correlations with clinical scores were generally moderate to high, but lower for instability. The MDC was 18.1%, the MCII was 25.2%, and the PASS was 77.6. No floor effect was observed. The B-B Score demonstrated excellent measurement properties in populations with rotator cuff conditions, proximal humerus fractures, and capsulitis, and can thus be used as a routine test to evaluate those patients.

Impact of a Swiss adverse drug event prevention collaborative.

RATIONALE, AIMS AND OBJECTIVES: The Hospital Federation of Vaud (Switzerland) used a Breakthrough Collaborative with the aim of reducing adverse drug events (ADEs) by 20% in 10 participating hospitals. METHODS: A set of interventions (covering patient identification, high-alert medication and medication preparation in the ward) was deployed over 18 months starting in October 2010. All hospitals monitored discrepancies between drugs prescribed and those prepared for administration, as well as the occurrence of ADEs using the ADE Trigger Tool for 18 months (cohort 1). A subset of five hospitals continued this monitoring for 12 additional months (cohort 2). RESULTS: In cohort 1, pill box discrepancies were present in 5.9% of doses (n = 9772) in 2011 and in 5.8% (n = 2251) in the first 3 months of 2012 (no statistical significance). There were no significant differences in the rate of ADEs/1000 doses across time (1.2 in 2010, 1.0 in 2011 and 1.0 in 2012). In cohort 2, pill box discrepancies were reduced from 6.5% (n = 4846 doses) in 2011 to 4.4% (n = 7355) in 2012 (P < 0.001) to 3.0% for the first 3 months of 2013 (n = 2251; P = 0.004). The rate of ADEs/1000 doses decreased (1.8 in 2010, 1.1 in 2011 and 0.6 in 2012/13 (P = 0.008 for 2010-2011, and P < 0.001 for 2011-2012/2013). CONCLUSIONS: Reductions in drug discrepancies and ADEs occurred in the cohort with the longer monitoring duration. Factors contributing to success may include the strategic status of the project, executive support, perseverance in post-intervention measurement, and institution-wide rather than partial deployment.

Bioimpedance spectroscopy for swelling evaluation following total knee arthroplasty: a validation study.

BACKGROUND: The evaluation of swelling is important for the outcome of total knee arthroplasty (TKA) surgery. The circumference or volume measurements are applicable at the bedside of the patient but are altered by muscular atrophy and the post-surgical dressing. Bioimpedance spectroscopy might overcome these limitations; however, it should be validated. This study aimed to explore the validity, the reliability and the responsiveness of bioimpedance spectroscopy for measuring swelling after TKA. METHODS: The degree of swelling in 25 patients undergoing TKA surgery was measured using bioimpedance spectroscopy (BIS R0), knee circumference and limb volume. The measurements were performed on D-1 (day before surgery), D + 2 (2 days after surgery) and D + 8 (8 days after surgery). The BIS R0 measurements were repeated twice, alternating between two evaluators. The percentage of the difference between the limbs was calculated for BIS R0, circumference and volume. The intra- and inter-observer intraclass correlation coefficients (ICCs), limits of agreement (LOA), effect size (Cohen's d), correlations between the methods and diagnostic sensitivity were calculated. RESULTS: BIS R0, circumference and volume detected swelling < 3.5% at D-1. The swelling at D2 and D8 was greater with BIS R0 [mean (SD) 29.9% (±9.8) and 38.27 (±7.8)] than with volume [14.7 (±9.5) and 14.9 (±8.2)] and circumference [11.1 (±5.7) and 11.7 (±4.1)]. The BIS R0 intra- and inter-evaluator ICCs ranged from 0.89 to 0.99, whereas the LOA were < 5.2%. The BIS R0 correlation was 0.73 with volume and 0.75 with circumference. The BIS R0 Cohen's d was 3.32 for the D-1-D2 evolution. The diagnostic sensitivity was 83% D2 and 96% at D8. CONCLUSION: Bioimpedance is a valid method for the evaluation of swelling following TKA. BIS R0 also demonstrated excellent intra- and inter-evaluator reliability. The diagnostic sensitivity and responsiveness is superior to that of concurrent methods. BIS R0 is an efficient method for post-surgical follow up at the bedside of the patient. The measurement of BIS R0 is a straightforward, valid, reliable and responsive method for lower limb swelling following TKA surgery that could be used in clinics and research.

Total hip replacement with a collarless polished cemented anatomic stem: clinical and gait analysis results at ten years follow-up.

PURPOSE: The aim of this study was to determine outcomes of total hip replacement (THR) with the Lemania cemented femoral stem. METHODS: A total of 78 THR patients were followed and compared to 17 "fit", healthy, elderly and 72 "frail" elderly subjects without THR, using clinical outcome measures and a portable, in-field gait analysis device at five and ten years follow-up. RESULTS: Forty-one patients (53%), mean age 83.4 years, available at ten years follow-up, reported very good to excellent satisfaction. Mean Harris Hip and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores were 81.2 and 10.5 points, respectively, with excellent radiological preservation of proximal femur bone stock. Spatial and temporal gait parameters were close to the fit group and better than the frail group. CONCLUSIONS: Lemania THR demonstrated very good, stable clinical and radiological results at ten years in an older patient group, comparable to other cemented systems for primary THR. Gait analysis confirmed good walking performance in a real-life environment.

Predictors of functional recovery in patients admitted to geriatric postacute rehabilitation.

OBJECTIVE: To examine characteristics associated with functional recovery in older patients undergoing postacute rehabilitation. DESIGN: Observational study. SETTING: Postacute rehabilitation facility. PARTICIPANTS: Patients (N=2754) aged ≥65 years admitted over a 4-year period. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: Functional status was assessed at admission and again at discharge. Functional recovery was defined as achieving at least 30% improvement on the Barthel Index score from admission compared with the maximum possible room for improvement. RESULTS: Patients who achieved functional recovery (70.3%) were younger and were more likely to be women, live alone, and be without any formal home care before admission, and they had fewer chronic diseases (all P<.01). They also had better cognitive status and a higher Barthel Index score both at admission (mean ± SD, 63.3±18.0 vs 59.6±24.7) and at discharge (mean ± SD, 86.8±10.4 vs 62.2±22.9) (all P<.001). In multivariate analysis, patients <75 years of age (adjusted odds ratio [OR]=1.51; 95% confidence interval [CI], 1.16-1.98; P=.003), women (adjusted OR=1.24; 95% CI, 1.01-1.52; P=.045), patients living alone (adjusted OR=1.61; 95% CI, 1.31-1.98; P<.001), and patients without in-home help prior to admission (adjusted OR=1.39; 95% CI, 1.15-1.69; P=.001) remained at increased odds of functional recovery. In addition, compared with those with moderate-to-severe cognitive impairment (Mini-Mental State Examination score <18), patients with mild-to-moderate impairment (Mini-Mental State Examination score 19-23) and those cognitively intact also had increased odds of functional recovery (adjusted OR=1.56; 95% CI, 1.13-2.15; P=.007; adjusted OR=2.21; 95% CI, 1.67-2.93; P<.001, respectively). CONCLUSIONS: Apart from sociodemographic characteristics, cognition is the strongest factor that identifies older patients more likely to improve during postacute rehabilitation. Further study needs to determine how to best adapt rehabilitation processes to better meet the specific needs of this population and optimize their outcome.
