Joint Trajectories of Cognition and Frailty and Associated Burden of Patient-Reported Outcomes.

ABSTRACT: OBJECTIVES:To evaluate joint trajectories of cognition and frailty and their association with the cumulative burden of patient-reported outcomes, including hospitalization, nursing home admission, and disability. DESIGN:Longitudinal study of 754 community-living persons aged 70 or older. PARTICIPANTS:690 participants who had a baseline and at least one follow-up assessment of cognition and frailty between 1998 and 2009. MEASUREMENTS:Cognition was assessed using the Mini-Mental State Examination (MMSE). Frailty was defined by the 5 criteria for the Fried phenotype: muscle weakness, exhaustion, low physical activity, shrinking, and slow walking speed. A group-based, mixture modeling approach was used to fit the joint trajectories of cognition and frailty. The cumulative burden of hospitalization, nursing home admission, and disability over 141 months associated with the joint trajectories was evaluated using a series of generalized estimating equation Poisson models. RESULTS:Four joint trajectories were identified, including No cognitive frailty (27.8%), Slow cognitive decline and progressive frailty (45.5%), Rapid cognitive decline and progressive frailty (20.2%), and Cognitive frailty (6.5%). For each joint trajectory group, the interval-specific incidence density rates of all patient-reported outcomes tended to increase over time, with the exception of hospitalization for which the increasing trend was apparent only for the Slow cognitive decline and progressive frailty group. The No cognitive frailty group had the lowest cumulative burden of all patient-reported outcomes [eg, nursing home admissions, 7.5/1000 person-months, 95% confidence interval (CI): 4.8-11.7], whereas the Cognitive frailty group had the highest cumulative burden (eg, nursing home admissions, 381.1/1000 person-months, 95% CI: 294.5-493.1), with the exception of hospitalization. Compared with the No cognitive frailty group, the 3 other joint trajectory groups all had significantly greater burden of the patient-reported outcomes. CONCLUSION:Community-living older persons exhibit distinct joint trajectories of cognition and frailty and experience an increasing burden of nursing home admission and disability as they age, with the greatest burden for those on a cognitive frailty trajectory.

Project description:BackgroundDespite widely reported success associated with hip and knee replacements, some patients remain dissatisfied with their outcomes. Patient activation, an individual's propensity to engage in adaptive health behaviors, has been measured as a potentially important factor contributing to health outcomes, cost, and patient experience of care. However, to our knowledge, it has not been studied in patients undergoing total joint arthroplasties (TJAs).Questions/purposesWe wanted to determine whether patients with higher activation scores would experience (1) greater resolution of pain and improved activity, (2) greater improvements in postoperative physical and mental health, and (3) greater patient satisfaction after primary THA or TKA.MethodsWe approached 174 patients and enrolled 135 who were undergoing primary THA or TKA at one of two hospitals between January 2013 and May 2014. Patient Activation Measure (PAM) scores were obtained preoperatively and patient-reported outcomes were assessed and completed for 125 patients pre- and postoperatively at the 6- or 12-month visit. We assessed pain and activity with the Hip Disability and Osteoarthritis Outcome Score (HOOS), Knee Injury and Osteoarthritis Outcome Score (KOOS), and University of California Los Angeles (UCLA) activity scores. We measured physical and mental health by calculating SF12v2® scores and measured patient satisfaction with the Hip and Knee Satisfaction Scale (HKSS). Linear regression models were used to test the association between baseline PAM and postoperative patient-reported outcomes.ResultsOverall, patients with a higher baseline PAM score experienced better pain relief using the HOOS/KOOS pain scores (R2=0.311, p=0.048) and symptoms using the HOOS/KOOS symptom scores (R2=0.272, p=0.021). In addition, higher PAM scores were associated with better postoperative mental health using the SF12v2® (R2=0.057, p<0.001), but were not associated with higher physical health (R2=0.176, p=0.173). Finally, higher PAM scores were associated with having greater postoperative satisfaction after surgery using the HKSS questionnaire (R2=0.048, p=0.023).ConclusionsHigher preoperative patient activation was associated with better pain relief, decreased symptoms, improved mental health, and greater satisfaction after TJA. Future efforts should be aimed at studying if improving patient activation before surgery results in better patient-reported outcomes after elective THA or TKA.Level of evidenceLevel II, prognostic study.

Project description:BackgroundHigh-value cancer care balances effective treatment with preservation of quality of life. Chemotherapy is known to affect patients' physical and psychological well-being negatively. Patient-reported outcomes (PROs) provide a means to monitor declines in a patients' well-being during treatment.MethodsWe identified 741 oncology patients undergoing chemotherapy in our electronic health record (EHR) system who completed Patient-Reported Outcomes Measurement Information System (PROMIS) surveys during treatment at a comprehensive cancer center, 2013-2018. PROMIS surveys were collected before, during, and after chemotherapy treatment. Linear mixed-effects models were performed to identify predictors of physical and mental health scores over time. A k-mean cluster analysis was used to group patient PROMIS score trajectories.ResultsMean global physical health (GPH) scores were 48.7 (SD 9.3), 47.7 (8.8), and 48.6 (8.9) and global mental health (GMH) scores were 50.4 (8.6), 49.5 (8.8), and 50.6 (9.1) before, during, and after chemotherapy, respectively. Asian race, Hispanic ethnicity, public insurance, anxiety/depression, stage III cancer, and palliative care were predictors of GPH and GMH decline. The treatment time period was also a predictor of both GPH and GMH decline relative to pre-treatment. Trajectory clustering identified four distinct PRO clusters associated with chemotherapy treatment.ConclusionsPatient-reported outcomes are increasingly used to help monitor cancer treatment and are now a part of care reimbursement. This study leveraged routinely collected PROMIS surveys linked to EHRs to identify novel patient trajectories of physical and mental well-being in oncology patients undergoing chemotherapy and potential predictors. Supportive care interventions in high-risk populations identified by our study may optimize resource deployment.Novelty and impactThis study leveraged routinely collected patient-reported outcome (PROMIS) surveys linked to electronic health records to characterize oncology patients' quality of life during chemotherapy. Important clinical and demographic predictors of declines in quality of life were identified and four novel trajectories to guide personalized interventions and support. This work highlights the utility of monitoring patient-reported outcomes not only before and after, but during chemotherapy to help advert adverse patient outcomes and improve treatment adherence.

Project description:Cirrhosis is associated with disabling symptoms and diminished health-related quality of life (HRQOL). However, for patients with compensated disease, data are limited regarding associations with poor patient-reported outcomes (PROs). We prospectively enrolled 300 patients with cirrhosis and portal hypertension without a history of hepatic encephalopathy (HE) and reviewed medical and pharmacy records. We characterized determinants of PROs using the 8-item Short-Form Health Survey (SF-8) scale (0-100) and sleep quality using the Pittsburgh Sleep Quality Index (PSQI; poor sleep >5). Disability and frailty measures were assessed using activities of daily living (ADLs), falls, hand-grip, and chair-stands. Cognitive function was measured using weighted-lures from the Inhibitory Control Test (ICT). The median age of our cohort was 60 (interquartile range [IQR], 52-66) years, 56.3% were male, and 70% Child class A. All patients had portal hypertension, 76% had varices, and 41% had a history of ascites (predominantly well controlled). The median Model for End-Stage Liver Disease with Sodium (MELD-Na) score was 9 (IQR, 7-13). The overall median SF-8 was 70 (IQR, 54-86). Multivariate analysis showed that after adjusting for age, sex, education, and MELD-Na, performance on chair-stands (9.28 HRQOL points [95% confidence interval {CI}, 4.76-13.8] per 10-stands), ADL dependence (-6.06 [-10.8 to -1.36]), opiate use (-5.01 [-7.84 to -2.19]), benzodiazepine use (-3.50 [-6.58 to -0.42]), and ICT performance (-0.10 [-0.20 to 0.001] per weighted-lure) were significantly associated with HRQOL. Among patients completing the ICT, poor HRQOL (score <50) was significantly associated with chair-stands (odds ratio [OR] per 10-stands, 0.24; 95% CI [0.11-0.56]) and weighted lures (OR per weighted-lure, 1.01 [1.00-1.03]). Poor sleep quality was associated with opiate use (OR, 2.85 [1.11-7.29]) and lures (OR per-lure, 1.03 [1.00-1.05]). Conclusion: Disability, chair-stand performance, cognitive dysfunction, as well as psychoactive medication use are significantly associated with PROs in patients with clinically stable cirrhosis.

Project description:BackgroundTotal joint arthroplasty (TJA) registries traditionally have focused on implant longevity and rates of revision surgery. Registries would benefit from the addition of standardized patient-reported outcomes (PROs) such as pain relief and improved physical function. However, PROs have not been routinely adopted, and their incorporation into TJA registries presents challenges.Questions/purposesWe review current PRO use by existing national registries, challenges to integrating PROs in national registries, lessons from national registries that have integrated PROs, and suggestions to guide future adoption of PROs.MethodsWe conducted a literature search of papers addressing PRO use in national knee and hip arthroplasty registries, resulting in 15 articles. These publications were supplemented by discussions with thought leaders from international registries. WHERE ARE WE NOW?: Some national TJA registries are collecting PROs and valuable research is emerging. However, challenges exist, such as selecting suitable PROs, selection bias in countries without government-mandated participation for all hospitals, and challenges with missing data. WHERE DO WE NEED TO GO?: The ideal system will incorporate PROs into TJA registries. In so doing, it will be important to choose suitable PROs and develop innovative methods to collect PROs to ensure complete data and sustainability. HOW DO WE GET THERE?: New methods are required to meet the challenges related to registry design, logistics of PRO collection, and registry cost and sustainability. Modifications to the traditional hospital- and implant-centric design and new procedures to collect complete data from both patients and clinicians may be necessary. For instance, England and Wales, New Zealand, and Sweden developed methods to collect PROs after TJA directly from patients and a US TJA registry collects PROs as the primary outcome. Finally, to assure long-term sustainability, PRO data must be valuable to multiple stakeholders, including patients, clinicians, researchers, and policy makers.

Project description:IntroductionHidradenitis suppurativa (HS) has a profound negative impact on patients' health-related quality of life (HRQoL). Here we summarize the evidence on HRQoL and Patient Reported Outcomes (PROs) in patients with HS in real-world settings by conducting a systematic literature review (SLR) of observational studies.MethodsData sources included MEDLINE, Embase & PsycINFO between January 1, 2010 and August 29, 2021, and conference proceedings between 2019 and 2021. Identified abstracts were reviewed and screened independently by two reviewers. Eligibility criteria included patients with HS of any severity, sample size ≥ 100, reporting PROs including HRQoL measures. Included studies were critically appraised.ResultsFifty-eight observational studies matched inclusion criteria. Dermatology Life Quality Index (DLQI) was the most commonly utilized instrument: 57% of included studies reported mean baseline DLQI scores, ranging between 8.4 and 16.9, indicating a very large impact on the patients' HRQoL. Higher scores were reported with increasing disease severity and among female patients. Pain was assessed mostly by an 11-point (0-10) numeric rating scale (NRS) with a mean baseline score ranging from 3.6 to 7.7 indicating moderate to high pain levels. There was a negative impact of HS on patients' psychological well-being, based on PRO scores related to depression and anxiety. A high proportion of sexual dysfunction was reported, with a larger impact on women than men. Work productivity and leisure activity were consistently found to be impaired in patients with HS.ConclusionsAll included studies reported a negative impact of HS on patients' lives. A diverse set of disease- and non-disease-specific PRO instruments were utilized highlighting the need for more consistent use of HS-specific validated PRO instruments to assess the impact of HS on the different aspects of patients' HRQoL to allow for data to be more meaningfully interpreted and compared in real-world settings. Patients with HS need better disease management approaches that address the observed low quality of life.
