Health-related quality of life and prosthesis use among patients amputated due to peripheral arterial disease – a one-year follow-up

Duration, frequency, and factors related to lower extremity prosthesis use: systematic review and meta-analysis

PURPOSE

A systematic review and meta-analysis investigating the duration and frequency of lower extremity prosthesis use and what factors were associated with changes in their use.

MATERIALS AND METHODS

A search of PubMed, CINAHL, and Scopus over 20 years revealed 2409 articles. After review, 29 studies remained, representing 4814 participants with lower limb loss. Quality, funding, publication, and quantitative analyses were addressed.

RESULTS

The mean prosthesis use was 9.6 (5.3) hours/day and 6.4 (1.9) days/week. Distal amputation sites averaged more hours/day of prostheses use than proximal amputations (13.2 [3.2] vs. 10.8 [5.0], p < .001). After hemipelvectomy or hip dislocations, average prostheses use was less hours/day (6.0 [4.7]) than after transfemoral (12.9 [4.8]) or transtibial amputations (14.0 [4.5]) (p < .05). Pooled effects revealed an association between comorbidities and abandonment (OR 0.35, p = .03). The data supported six empirical evidence statements concerning age, sex, social support, amputation proximity, balance, skin condition, comorbidities, pain, falls, and fitness in association with changes in prosthesis utilization.

CONCLUSIONS

The study provided systematic data on lower-extremity prosthesis use, thus helping to inform clinical decision-making and patient education. It also elucidated a path for future studies focused on modifiable factors related to prosthesis use and related outcomes.Implications for rehabilitationLower limb loss can trigger costly and debilitating sequela, which could be mitigated by increased prosthesis use and functionality, but there is no consensus on how often prostheses are being used and what affects changes in their use.When counseling patients on what they can expect after a lower extremity amputation and to set goals, the aggregated means of 9.6 (5.3) hours per day and 6.4 (1.9) days per week can be informative.Individuals who use a lower extremity prosthesis or may have to use one in the future can increase their prosthesis use and mobility by limiting further health deterioration.Rehabilitative care involving the multidisciplinary prioritization of proper socket fit, fitness training, gait training, and social support is associated with increased prosthetic device usage.

Racial disparities in prosthesis abandonment and mobility outcomes after lower limb amputation from a dysvascular etiology in a veteran population

BACKGROUND

Non-Hispanic Black (NHB) individuals have higher rates of amputation and increased risk of a transfemoral amputation due to dysvascular disease than non-Hispanic White (NHW) individuals. However, it is unclear if NHB individuals have differences in prosthesis use or functional outcomes following an amputation.

OBJECTIVE

To determine if there are racial disparities in prosthesis abandonment and mobility outcomes in veterans who have undergone their first major unilateral lower extremity amputation (LEA) due to diabetes and/or peripheral artery disease.

DESIGN

National cohort study that identified individuals retrospectively through the Veterans Affairs (VA) Corporate Data Warehouse (CDW) from March 1, 2018, to November 30, 2020, then prospectively collected their self-reported prosthesis abandonment and mobility. Multiple logistic regression was used to control for potential confounders and identify potential effect modifiers.

SETTING

The VA CDW, participant mailings and phone calls.

PARTICIPANTS

Three hundred fifty-seven individuals who underwent an incident transtibial or transfemoral amputation due to diabetes and/or peripheral arterial disease.

INTERVENTIONS

Not applicable.

MAIN OUTCOMES MEASURES

(1) Self-reported prosthesis abandonment. (2) Level of mobility assessed using the Locomotor Capabilities Index.

RESULTS

Rurally located NHB individuals without a major depressive disorder (MDD) had increased odds of abandoning their prosthesis (adjusted odds ratios [aOR] = 5.3; 95% confidence interval [CI]: [1.3-21.1]). This disparity was nearly three times as large for rurally located NHB individuals with MDD diagnosis, compared with other races from rural areas and with MDD (aOR = 15.8; 95% CI, 2.5-97.6). NHB individuals living in an urban area were significantly less likely to achieve advanced mobility, both with MDD (aOR=0.16; 95% CI: [0.04-7.0]) and without MDD (aOR = 0.26; 95% CI: [0.09-0.73]).

CONCLUSIONS

This study demonstrated that health care disparities persist for NHB veterans following a dysvascular LEA, with increased prosthesis abandonment and worse mobility outcomes.

Needs of Family Caregivers of People with Lower Limb Amputations: A Scoping Review

Lower limb amputation affects several parameters of a patient's life. Family caregivers providing care for these patients experience multiple feelings and needs; knowing caregivers' needs is essential to prepare them for this new role, as well as the health planning of this type of care. This scoping review aimed to identify and map the needs of family caregivers of people with lower limb amputations. This scoping review was conducted in accordance with the JBI methodological framework and the PRISMA-ScR reporting guidelines. A bibliographical search was carried out on the needs of family caregivers of lower limb amputees in 15 databases. Two independent reviewers extracted data using a data extraction tool developed for this scoping review. Eight studies were included in the present review (n = 6 quantitative studies; n = 2 reviews). Results indicate that family caregivers of people with lower limb amputations may experience an extensive range of needs, as follows: (i) mental health and psychological support, (ii) physical health, (iii) health and well-being, (iv) supportive care, (v) social support, and (vi) educational/informational support. The needs identified in this review can help to develop interventions and programs that provide better support during the situational transition process.

Factors influencing satisfaction with prosthetic and orthotic services - a national cross-sectional study in Sweden

PURPOSE

To evaluate client satisfaction with prosthetic and orthotic services in Sweden, determine if satisfaction differs between clients using different devices and identify factors which influence client satisfaction.

MATERIALS AND METHODS

A cross-sectional design was used to survey 7318 clients. The survey included items related to demographics, quality of life, device comfort, device use, the extent to which clients' needs were met and satisfaction with services. Ethics approval was provided by the Swedish Ethical Review Authority.

RESULTS

A total of 2925 surveys were returned reflecting a response rate of 41%. Mean OPUS-CSS point score was 61.9(SD 16.8) with differences observed between device categories (p < 0.001). Factors that were identified as most positively influencing client satisfaction were, being a limb prosthesis user and being under 65 years. When analysing scores for individual OPUS items breast prosthesis users scored higher than users of other devices. Clients were most satisfied with the level of respect they were shown by staff (mean = 2.72/3) and less satisfied with coordination of services with other therapists/doctors(mean = 1.88/3).

CONCLUSIONS

Prosthetic and orthotic users are reasonably satisfied with the services they receive. Attention should be directed towards understanding why prosthetic users are more satisfied than orthotic users and why clients under 65 years report higher satisfaction scores.

Long-term risk prediction after major lower limb amputation: 1-year results of the PERCEIVE study

BACKGROUND

Decision-making when considering major lower limb amputation is complex and requires individualized outcome estimation. It is unknown how accurate healthcare professionals or relevant outcome prediction tools are at predicting outcomes at 1-year after major lower limb amputation.

METHODS

An international, multicentre prospective observational study evaluating healthcare professional accuracy in predicting outcomes 1 year after major lower limb amputation and evaluation of relevant outcome prediction tools identified in a systematic search of the literature was undertaken. Observed outcomes at 1 year were compared with: healthcare professionals' preoperative predictions of death (surgeons and anaesthetists), major lower limb amputation revision (surgeons) and ambulation (surgeons, specialist physiotherapists and vascular nurse practitioners); and probabilities calculated from relevant outcome prediction tools.

RESULTS

A total of 537 patients and 2244 healthcare professional predictions of outcomes were included. Surgeons and anaesthetists had acceptable discrimination (C-statistic = 0.715), calibration and overall performance (Brier score = 0.200) when predicting 1-year death, but performed worse when predicting major lower limb amputation revision and ambulation (C-statistics = 0.627 and 0.662 respectively). Healthcare professionals overestimated the death and major lower limb amputation revision risks. Consultants outperformed trainees, especially when predicting ambulation. Allied healthcare professionals marginally outperformed surgeons in predicting ambulation. Two outcome prediction tools (C-statistics = 0.755 and 0.717, Brier scores = 0.158 and 0.178) outperformed healthcare professionals' discrimination, calibration and overall performance in predicting death. Two outcome prediction tools for ambulation (C-statistics = 0.688 and 0.667) marginally outperformed healthcare professionals.

CONCLUSION

There is uncertainty in predicting 1-year outcomes following major lower limb amputation. Different professional groups performed comparably in this study. Two outcome prediction tools for death and two for ambulation outperformed healthcare professionals and may support shared decision-making.

What Is Hidden behind Amputation? Quanti-Qualitative Systematic Review on Psychological Adjustment and Quality of Life in Lower Limb Amputees for Non-Traumatic Reasons

OBJECTIVE

This systematic review aims to investigate Quality of Life (QoL)/Health Related Quality of Life (HRQoL) and psychological adjustment in non-traumatic lower limb amputees (LLA).

METHODS

PubMed, Scopus, and Web of Science databases were used for the literature search. Studies were read and analysed using the (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) PRISMA statement procedure.

RESULTS

The literature search retrieved 1268 studies, of which 52 were included in the systematic review. Overall, psychological adjustment, especially depression with or without anxiety symptoms, influences the QoL/HRQoL in this clinical population. Other factors influencing QoL/HRQoL include subjective characteristics, physical aspects, the cause and level of the amputation, relational aspects, social support, and the doctor-patient relationship. In addition, the patient's emotional-motivational status, depression and/or anxiety symptoms, and acceptance play a key role in the subsequent rehabilitation process.

CONCLUSIONS

In LLA patients, psychological adjustment is a complex and multifaceted process, and QoL/HRQoL may be influenced by various factors. Shedding light on these issues may provide useful suggestions for promoting clinical and rehabilitative interventions that may be tailored and effective in this clinical population.

GGEM: Gender, Geography, and EMployment differences based on mobility levels among lower limb prosthesis users living in the United States

BACKGROUND

For individuals with a disability, an increase in functional mobility may improve their quality of life and well-being. Greater understanding is needed on how factors such as gender, geography, and employment may play a role in mobility levels among individuals with lower limb amputation.

OBJECTIVES

To assess the relationship between gender, geography, and employment status on mobility among lower limb prosthesis users.

METHODS

A cross-sectional analysis of 7,524 patient mobility outcomes completed across the United States was performed. The regression model included the independent variables, such as age, gender, region, employment status, and amputation level. Mobility was entered as the dependent variable.

RESULTS

Individuals who were employed had 3.6 times the odds of reaching increased mobility (Prosthetic Limb Users' Survey of Mobility ≥ 50) than those unemployed (odds ratio 3.56, 95% confidence interval 3.10-4.09). Gender and geography were significantly associated with mobility as well.

CONCLUSIONS

Being employed is associated with greater odds of reaching increased mobility. Addressing factors such as returning to employment may aid in improving mobility levels among prosthesis users.

Exploring patients' experiences of analgesia after major lower limb amputation: a qualitative study

OBJECTIVES

To explore patient experiences, understanding and perceptions of analgesia following major lower limb amputation.

DESIGN

Qualitative interview study, conducted as part of a randomised controlled feasibility trial.

SETTING

Participants were recruited from two general hospitals in South Wales.

PARTICIPANTS

Interview participants were patients enrolled in PLACEMENT (Perineural Local Anaesthetic Catheter aftEr Major lowEr limb amputatioN Trial): a randomised controlled feasibility trial comparing the use of perineural catheter (PNC) versus standard care for postoperative pain relief following major lower limb amputation. PLACEMENT participants who completed 5-day postoperative follow-up, were able and willing to participate in a face-to-face interview, and had consented to be contacted, were eligible to take part in the qualitative study. A total of 20 interviews were conducted with 14 participants: 10 male and 4 female.

METHODS

Semi-structured, face-to-face interviews were conducted with participants over two time points: (1) up to 1 month and (2) at least 6 months following amputation. Interviews were audio-recorded, transcribed verbatim and analysed using a framework approach.

RESULTS

Interviews revealed unanticipated benefits of PNC usage for postoperative pain relief. Participants valued the localised and continuous nature of this mode of analgesia in comparison to opioids. Concerns about opioid dependence and side effects of pain relief medication were raised by participants in both treatment groups, with some reporting trying to limit their intake of analgesics.

CONCLUSIONS

Findings suggest routine placement of a PNC following major lower limb amputation could reduce postoperative pain, particularly for patient groups at risk of postoperative delirium. This method of analgesic delivery also has the potential to reduce preoperative anxiety, alleviate the burden of pain management and minimise opioid use. Future research could further examine the comparison between patient-controlled analgesia and continuous analgesia in relation to patient anxiety and satisfaction with pain management.

Health-related quality of life after a one-year follow-up of patients undergoing endovascular leg revascularization

BACKGROUND

Lower limb revascularization not only improves walking distance, but also disease-specific and general health-related quality of life (HRQoL). Therefore, we analyzed changes in HRQoL after endovascular leg revascularization in patients with chronic lower limb ischemia during a one-year follow-up.

PATIENTS AND METHODS

The WHOQOL-BREF questionnaire was completed by 50 patients with intermittent claudication (IC) and 50 patients with chronic limb-threatening ischemia (CLTI) who underwent endovascular revascularization with a stent implantation, as well as 40 patients with IC not requiring endovascular intervention who received medical management only. The survey was completed before and then 3 and 12 months after an intervention.

RESULTS

Patients with CLTI before endovascular intervention had the lowest HRQoL in the somatic, psychological, social, and environmental domains. After endovascular revascularization, these patients achieved the greatest improvement in HRQoL. Scores in the HRQoL domains correlated with Rutherford class, ankle-brachial index, and walking distance. The initial score in the somatic domain predicted the risk of target lesion revascularization (TLR) during the one-year follow-up.

CONCLUSIONS

Endovascular leg revascularization improved patients' functioning, not only in the physical, but also in the psychological, environmental and social domains of HRQoL. A higher score in the somatic domain of HRQoL before and at 3 months after an intervention predicted the risk of TLR during the one-year follow-up. It is recommended that scores for general HRQoL domains are added to the standard measures of the direct outcome of leg revascularization due to their one-year prognostic value.

Understanding transitions in care for people with major lower limb amputations from inpatient rehabilitation to home: a descriptive qualitative study

PURPOSE

To understand how people with major limb amputation experience the transition in care from inpatient rehabilitation to the community.

METHOD

A qualitative study was conducted using semi-structured interviews. Individuals were eligible if they had undergone a major lower limb amputation and had been discharged from inpatient rehabilitation to the community within one to twelve months. Interviews explored participants' experiences and factors associated with the transition in care. The interviews were audio-recorded, transcribed, and thematically analyzed.

RESULTS

Nine individuals with major lower limb amputation participated. Five themes were identified to describe the transition in care experience: (a) Preparedness: differing experiences during inpatient rehabilitation; (b) Challenges with everyday tasks: "everything has to be thought out"; (c) Importance of coping strategies; "gradually you accept it more and more" (d) Importance of support and feeling connected; "if I needed anything, they're right there" and (e) Not everyone has access to the same resources: "left to your own devices".

CONCLUSIONS

The identified themes concurrently influenced the transition from inpatient rehabilitation to the community. Common challenges during the initial transition were identified. Areas of improvement within inpatient rehabilitation included individualized care, discussions surrounding expectations, and better access to ongoing community support.Implication for rehabilitationTransition in care are difficult and vulnerable times for people with major lower limb amputation, especially when transitioning home following inpatient rehabilitation.Rehabilitation should prepare individuals for completing meaningful tasks in the home and community.Access to ongoing support in the community in the form of practical and emotional support can ease the challenges of transitioning home.
