Unicompartmental Knee Arthroplasty in Octogenarians versus Younger Patients: A Comparison of 30-Day Outcomes

As the United States' octogenarian population (persons 80-89 years of age) continues to grow, understanding the risk profile of surgical procedures in elderly patients becomes increasingly important. The purpose of this study was to compare 30-day outcomes following unicompartmental knee arthroplasty (UKA) in octogenarians with those in younger patients. The American College of Surgeons National Surgical Quality Improvement Program database was queried. All patients, aged 60 to 89 years, who underwent UKA from 2005 to 2016 were included. Patients were stratified by age: 60 to 69 (Group 1), 70 to 79 (Group 2), and 80 to 89 years (Group 3). Multivariate regression models were estimated for the outcomes of hospital length of stay (LOS), nonhome discharge, morbidity, reoperation, and readmission within 30 days following UKA. A total of 5,352 patients met inclusion criteria. Group 1 status was associated with a 0.41-day shorter average adjusted LOS (99.5% confidence interval [CI]: 0.67-0.16 days shorter, p < 0.001) relative to Group 3. Group 2 status was not associated with a significantly shorter LOS compared with Group 3. Both Group 1 (odds ratio [OR] = 0.15, 99.5% CI: 0.10-0.23) and Group 2 (OR = 0.33, 99.5% CI: 0.22-0.49) demonstrated significantly lower adjusted odds of nonhome discharge following UKA compared with Group 3. There was no significant difference in adjusted odds of 30-day morbidity, readmission, or reoperation when comparing Group 3 patients with Group 1 or Group 2. While differences in LOS and nonhome discharge were seen, octogenarian status was not associated with increased adjusted odds of 30-day morbidity, readmission, or reoperation. Factors other than age may better predict postoperative complications following UKA.

Intensive Care Unit-Acquired Weakness: Implications for Case Management

PURPOSE

The purpose of this case study is to provide a specific example of the disease trajectory for one patient's experience with intensive care unit-acquired weakness (ICUAW). This case study provides those in case management with an overview of some of the common signs and symptoms of ICUAW, as well as the possible prognosis and recovery from ICUAW.

PRIMARY PRACTICE SETTING

The events in this case study take place in the acute care setting including the intensive care unit of a mid-sized health center, a general medical-surgical (med-surg) unit, and a long-term acute care facility.

CONCLUSIONS

ICUAW affects the clinical, functional, and financial outcomes of patients. If the patient survives, their quality of life and the quality of life of their family members could be severely impacted. Case management practice has a significant role in coordinating care for those diagnosed with ICUAW. Case managers can use knowledge about ICUAW to improve the patient's transition throughout the hospital stay, improve discharge recommendations, and improve the patient's short-term and long-term outcomes. This may reduce unnecessary utilization of health care resources.

Unmet health and rehabilitation needs of people with long-term neurological conditions in Queensland, Australia

The survival and life expectancy rates of people with traumatic and degenerative neurological conditions are increasing, sometimes up to several decades. Yet compared to the general population, people with a disability continue to experience poorer health and are at greater risk of developing secondary health problems and facing barriers to services they require. These trends have significant implications for provision of health and rehabilitation services. In this study, the adequacy of health and rehabilitation services provided to people with long-term neurological conditions and their unmet needs were explored from the perspectives of individual users, their nominated family members and key service providers. A qualitative research design with maximum variation sampling was used. Data were collected from semi-structured interviews with 65 participants comprising 25 long-term care service users, nominated family members or friends (n = 22) and care service providers (n = 18) in Queensland, Australia. All service users needed assistance with usual daily activities, and 22 were wheelchair dependent. The hours of funded personal care ranged from 2 to 201 hours per week. Data were analysed using framework analysis. Participants generally perceived that specialist medical and hospital services were adequate and satisfactory. They valued supportive health and rehabilitation professionals and receiving client-centred physical rehabilitation. However, the majority of participants (n = 17) had perceived unmet needs for physical rehabilitation (n = 14), other health or rehabilitation services (n = 10) or counselling (n = 6). Community-based physical maintenance rehabilitation was often perceived as inadequate, costly or inconveniently located. Participants highlighted the importance of personal and family counselling and information provision at time points such as diagnosis. The findings contribute to the limited international evidence on the gaps in health and rehabilitation services for people with neurological conditions receiving lifetime care services in the community. A continuum of integrated rehabilitation services to minimise avoidable impairments, optimise independence and functioning, and sustain quality of life is warranted.

Protocol of a longitudinal cohort study on physical activity behaviour in physically disabled patients participating in a rehabilitation counselling programme: ReSpAct

INTRODUCTION

Stimulating physical activity behaviour in persons with a physical disability is important, especially after discharge from rehabilitation. A tailored counselling programme covering both the period of the rehabilitation treatment and the first months at home seems on the average effective. However, a considerable variation in response is observed in the sense that some patients show a relevant beneficial response while others show no or only a small response on physical activity behaviour. The Rehabilitation, Sports and Active lifestyle (ReSpAct) study aims to estimate the associations of patient and programme characteristics with patients' physical activity behaviour after their participation in a tailored counselling programme.

METHODS AND ANALYSIS

A questionnaire-based nationwide longitudinal prospective cohort study is conducted. Participants are recruited from 18 rehabilitation centres and hospitals in The Netherlands. 2000 participants with a physical disability or chronic disease will be followed during and after their participation in a tailored counselling programme. Programme outcomes on physical activity behaviour and patient as well as programme characteristics that may be associated with differences in physical activity behaviour after programme completion are being assessed. Data collection takes place at baseline and 14, 33 and 52 weeks after discharge from rehabilitation.

ETHICS AND DISSEMINATION

The study protocol has been approved by the Medical Ethics Committee of the University Medical Centre Groningen and at individual participating institutions. All participants give written informed consent. The study results will provide new insights into factors that may help explain the differences in physical activity behaviour of patients with a physical disability after they have participated in the same physical activity and sports stimulation programme. Thereby, it will support healthcare professionals to tailor their guidance and care to individual patients in order to stimulate physical activity after discharge in a more efficient and effective way.

Effect of in-home and community-based services on the functional status of elderly in the long-term care insurance system in Japan

BACKGROUND

Japan is setting the pace among aging societies of the world. In 2005, Japan became the country with the highest proportion of elderly persons in the world. To deal with the accelerated ageing population and with an increased demand for long-term care services, in April 2000 the Japanese government introduced a mandatory social Long-Term Care Insurance System (LTCI), making long-term care services a universal entitlement for elderly. Overseas literature suggests that the effectiveness of a home visiting program is uncertain in terms of preventing a decline in the functional status of elderly individuals. In Japan, many studies regarding factors associated with LTC service utilization have been conducted, however, limited evidence about the effect of LTC services on the progression of recipient disability is available.

METHODS

Data were obtained from databases of the LTC insurer of City A. To examine the effect of in-home and community-based services on disability status of recipients, a survival analysis in a cohort of moderately disabled elderly people, was conducted.

RESULTS

The mean age of participants was 81 years old, and females represented 69% of the participants. A decline or an improvement in functional status, was observed in 43% and 27% of the sample, respectively. After controlling for other variables, women had a significantly greater probability of improving their functional status during all phases of the observation period. The use of "one service" and the amount of services utilized (days/month), were marginally (p = < 0.10) associated with a greater probability of improving their functional status at 12 months into the observation period.

CONCLUSIONS

The observed effects of in-home and community-based services on disability transition status were considered fairly modest and weak, in terms of their ability to improve or to prevent a decline in functional status. We suggest two mechanisms to explain these findings. First, disability transition as a measure of disability progression may not be specific enough to assess changes in functional status of LTCI recipients. Secondly, in-home and community-based services provided in City A, may be inappropriate in terms of intensity, duration or quality of care.

Exercise capacity in patients with severe symptomatic aortic stenosis before and six months after transcatheter aortic valve implantation

Few data exist on the use of the 6-minute walk test (6MWT) to measure the exercise capacity of patients with severe symptomatic aortic stenosis considered at very high surgical risk. The objectives of the present prospective study were (1) to determine the feasibility and safety of the 6MWT as a measure of exercise capacity before and after transcatheter aortic valve implantation (TAVI), and (2) to determine the clinical and hemodynamic parameters associated with the exercise capacity changes in such patients. A total of 64 patients (age 80 ± 8 years, logistic European System for Cardiac Operative Risk Evaluation score 21 ± 15%, Society of Thoracic Surgeons' score 7.5 ± 3.9%) who had undergone successful TAVI were included. The 6MWT was performed within the month before TAVI and at the 6-month follow-up visit. The mean distance walked increased from 165.3 ± 79.7 to 231.7 ± 88.9 m (p <0.0001); however, up to 25% of the patients did not improve or even decreased their exercise capacity. After adjustment for the baseline distance walked, multilinear regression analysis showed that a greater degree of renal dysfunction, as evaluated by the serum creatinine levels (r(2) = 0.05, p = 0.03), lower postprocedural hemoglobin values (r(2) = 0.13, p = 0.0012), and a longer hospitalization length (r(2) = 0.08, p = 0.007) were associated with lower improvement in exercise capacity. In conclusion, exercise capacity, as evaluated by the 6MWT, was very poor in patients with severe symptomatic aortic stenosis considered at very high surgical risk. TAVI was associated with a significant increase in exercise capacity, although no improvement was observed in 1/4 of the patients. A greater degree in renal dysfunction, lower postprocedural hemoglobin values, and longer hospitalization stay were predictors of lower improvement in exercise capacity after TAVI. These results suggest that the 6MWT might become an important tool as a part of the evaluation process for TAVI candidates.

Consequences of stroke in community-dwelling elderly: the health and retirement study, 1998 to 2008

BACKGROUND AND PURPOSE

Stroke survivors are at risk of developing comorbidities that further reduce their quality of life. The purpose of this study was to determine the risk of developing a secondary health problem after stroke.

METHODS

We performed a case-control analysis using 6 biennial interview waves (1998 to 2008) of the Health and Retirement Study. We compared 631 noninstitutionalized individuals who had a single stroke with 631 control subjects matched for age, gender, and interview wave. We studied sleep problems, urinary incontinence, motor impairment, falls, and memory deficits among the 2 groups.

RESULTS

Stroke survivors frequently developed new or worsened motor impairment (33%), sleep problems (up to 33%), falls (30%), urinary incontinence (19%), and memory deficits (9%). As compared with control subjects, the risk of developing a secondary health problem was highest for memory deficits (OR, 2.45; 95% CI, 1.34 to 4.46) followed by urinary incontinence (OR, 1.86; 95% CI, 1.31 to 2.66), motor impairment (OR, 1.61; 95% CI, 1.16 to 2.24), falls (OR, 1.5; 95% CI, 1.12 to 2.0), and sleep disturbances (OR, 1.49; 95% CI, 1.09 to 2.03). In contrast, stroke survivors were not more likely to injure themselves during a fall (OR, 1.14; 95% CI, 0.72 to 1.79). After adjusting for cardiovascular risk factors, social status, psychiatric symptoms, and pain, the risks of falling or developing sleep problems were not different from the control subjects.

CONCLUSIONS

The risk of developing a secondary health problem that can impact daily life is markedly increased after stroke. A better understanding of frequencies and risks for secondary health problems after stroke is necessary for designing better preventive and rehabilitation strategies.

Systematic literature review on ICF from 2001 to 2009: its use, implementation and operationalisation

PURPOSE

To present a systematic literature review on the state of the art of the utilisation of the International Classification of Functioning, Disability and Health (ICF) since its release in 2001.

METHOD

The search was conducted through EMBASE, MEDLINE and PsychInfo covering the period between 2001 and December 2009. Papers were included if ICF was mentioned in title or abstract. Papers focussing on the ICF-CY and clinical research on children and youth only were excluded. Papers were assigned to six different groups covering the wide scenario of ICF application.

RESULTS

A total of 672 papers, coming from 34 countries and 211 different journals, were included in the analysis. The majority of publications (30.8%) were conceptual papers or papers reporting clinical and rehabilitation studies (25.9%). One-third of the papers were published in 2008 and 2009.

CONCLUSIONS

The ICF contributed to the development of research on functioning and on disability in clinical, rehabilitation as well as in several other contexts, such as disability eligibility and employment. Diffusion of ICF research and use in a great variety of fields and scientific journals is a proof that a cultural change and a new conceptualisation of functioning and disability is happening.
