Development of the AMPDECIDE Decision Aid to Facilitate Shared Decision Making in Patients Facing Amputation Secondary to Chronic Limb Threatening Ischemia.

INTRODUCTION: We developed a patient decision aid to enhance patient participation in amputation level decision making when there is a choice between a transmetatarsal or transtibial amputation. METHODS: In accordance with International Patient Decision Aid Standards, we developed an amputation level patient decision aid for patients who are being considered for either a transmetatarsal or transtibial amputation, incorporating qualitative literature data, quantitative literature data, qualitative provider and patient interviews, expert panel input and iterative patient feedback. RESULTS: The rapid qualitative literature review and qualitative interviews identified five domains outcome priority domains important to patients facing amputation secondary to chronic limb threatening ischemia: 1) the ability to walk, 2) healing and risk for reamputation, 3) rehabilitation program intensity, 4) ease of prosthetic use, and 5) limb length after amputation. The rapid quantitative review identified only two domains with adequate evidence comparing differences in outcomes between the two amputation levels: mobility and reamputation. Patient, surgeon, rehabilitation and decision aid expert feedback allowed us to integrate critical facets of the decision including addressing the emotional context of loss of limb, fear and anxiety as an obstacle to decision making, shaping the decision in the context of remaining life years, and how to facilitate patient knowledge of value tradeoffs. CONCLUSIONS: Amputation level choice is associated with significant outcome trade-offs. The AMPDECIDE patient decision aid can facilitate acknowledgment of patient fears, enhance knowledge of amputation level outcomes, assist patients in determining their personal outcome priorities, and facilitate shared amputation level decision making.

The Effect of Prosthetic Limb Sophistication and Amputation Level on Self-reported Mobility and Satisfaction With Mobility.

OBJECTIVE: To determine if lower limb prosthesis (LLP) sophistication is associated with patient-reported mobility and/or mobility satisfaction, and if these associations differ by amputation level. DESIGN: Cohort study that identified participants through a large national database and prospectively collected self-reported patient outcomes. SETTING: The Veterans Administration (VA) Corporate Data Warehouse, the National Prosthetics Patient Database, participant mailings, and phone calls. PARTICIPANTS: 347 Veterans who underwent an incident transtibial (TT) or transfemoral (TF) amputation due to diabetes and/or peripheral artery disease and received a qualifying LLP between March 1, 2018, and November 30, 2020. INTERVENTIONS: Basic, intermediate, and advanced prosthesis sophistication was measured by the accurate and reliable PROClass system. MAIN OUTCOME MEASURE: Patient-reported mobility using the advanced mobility subscale of the Locomotor Capabilities Index-5; mobility satisfaction using a 0-10-point Likert scale. RESULTS: Lower limb amputees who received intermediate or advanced prostheses were more likely to achieve advanced mobility than those who received basic prostheses, with intermediate nearing statistical significance at nearly twice the odds (adjusted odds ratio (aOR)=1.8, 95% confidence interval (CI), .98-3.3; P=.06). The association was strongest in TF amputees with over 10 times the odds (aOR=10.2, 95% CI, 1.1-96.8; P=.04). The use of an intermediate sophistication prosthesis relative to a basic prosthesis was significantly associated with mobility satisfaction (adjusted ß coefficient (aß)=.77, 95% CI, .11-1.4; P=.02). A statistically significant association was only observed in those who underwent a TT amputation (aß=.79, 95% CI, .09-1.5; P=.03). CONCLUSIONS: Prosthesis sophistication was not associated with achieving advanced mobility in TT amputees but was associated with greater mobility satisfaction. In contrast, prosthesis sophistication was associated with achieving advanced mobility in TF amputees but was not associated with an increase in mobility satisfaction.

The effect of depression on prosthesis prescription in men and women who have undergone a lower limb amputation.

PURPOSE: To determine gender disparities and potential factors that modify prosthesis prescription practices in veteran patients who have undergone their first major unilateral amputation due to diabetes or peripheral arterial disease. MATERIALS AND METHODS: A retrospective cohort study using the VA Corporate Data Warehouse to compare prosthesis prescription rates and time to prescription between men and women veterans. The primary exposure was gender. The primary outcome was a qualifying prosthesis prescription within 12 months of the incident amputation. The secondary outcome was time to prosthesis prescription. Multiple logistic and linear regression was used to control for potential confounders and identify potential effect modification. RESULTS: 2,862 individuals met study criteria, with 1690 (60%) prescribed a qualifying prosthesis. Men were more likely to receive a prosthesis prescription than women (59% versus 45%, respectively; p = 0.03). This difference was observed primarily among those with a diagnosis of major depressive disorder. In this subgroup, the odds of men receiving a prosthesis over women was over 3 times (adjusted odds ratio = 3.3; 95% Confidence Interval, 1.5, 7.4). Men had a mean shorter time to prescription compared to women (112 ± 72 versus 136 ± 79 days, respectively, p = 0.08).Depression in women negatively impacts their prosthesis prescription rates and time to prescription compared to men. This disparity may have significant impacts on future function and quality of life.Implications for RehabilitationThis study found that men more commonly received a prosthesis prescription and received it earlier than women.This disparity was most extreme among women who had been diagnosed with major depressive disorder.Providers should identify at risk patients early and consider targeted interventions to address depression during the preoperative and immediate postoperative phases.Future research should continue to work to identify gender-specific needs that exacerbate disparity.

PROClass: The Development and Validation of a Novel Prosthetic Component Sophistication Classification System.

Objective: To develop a lower limb prosthesis (LLP) sophistication classification system that categorizes prosthetic component prescriptions into "basic," "intermediate," and "advanced" and assess its content validity, reliability, and accuracy. Design: Classification development and validation study. Setting: The Veterans Affairs (VA) Corporate Data Warehouse database and National Prosthetics Patient Database were used to identify patients undergoing their first amputation at the transtibial or transfemoral level due to diabetes or peripheral artery disease and to identify the associated codes for each LLP. Participants: An expert panel of 6 nationally recognized certified prosthetists, a national expert in VA prosthetics data and coding, a physical medicine and rehabilitation physician, and an epidemiologist developed an LLP classification system (PROClass) using 30 transfemoral and transtibial lower limb amputees. Main Outcome Measures: The expert panel reviewed 20 consecutive participants meeting study criteria for the development of the PROClass system and a subsequent 30 consecutive cases for assessing the inter- and intra-rater reliability and accuracy. Results: The interrater and intrarater reliability was almost perfect with Gwet's AC1 values ranging from .82 to .96 for both expert panel members and research assistants. The accuracy of the research assistant's classifications to the "criterion standard" was excellent with Gwet's AC1 values ranging between .75 and .92. Conclusions: PROClass is a pragmatic, reliable, and accurate prosthetic classification system with strong face validity that will enable the classification of prosthetic components used for large data set research aimed at evaluating important clinical questions such as the effects of sophistication on patient outcomes.

Comparing Patient and Provider Priorities Around Amputation Level Outcomes Using Multiple Criteria Decision Analysis.

BACKGROUND: Patients with chronic limb threatening ischemia may require a transmetatarsal amputation (TMA) or a transtibial amputation. When making an amputation-level decision, these patients face a tradeoff-a TMA preserves more limb and may provide better mobility but has a lower probability of primary wound healing and may therefore result in additional same or higher level amputation surgeries with an associated negative impact on function. Understanding differences in how patients and providers prioritize these tradeoffs and other outcomes may enhance shared decision-making. OBJECTIVES: Compare patient priorities with provider perceptions of patient priorities using Multiple Criteria Decision Analysis (MCDA). METHODS: The MCDA Analytic Hierarchy Process was chosen due to its low cognitive burden and ease of implementation. We included 5 criteria (outcomes): ability to walk, healing after amputation surgery, rehabilitation program intensity, limb length, and ease of use of prosthetic/orthotic device. A national sample of dysvascular lower-limb amputees and providers were recruited from the Veterans Health Administration with the MCDA administered online to providers and telephonically to patients. RESULTS: Twenty-six dysvascular amputees and 38 providers participated. Fifty percent of patients had undergone a TMA; 50%, a transtibial amputation. When compared to providers, patients placed higher value on TMA (72% vs. 63%). Patient versus provider priorities were ability to walk (47% vs. 42%), healing (18% vs. 28%), ease of prosthesis use (17% vs. 13%), limb length (11% vs. 13%), and then rehabilitation intensity (7% vs. 6%). LIMITATIONS: Our sample may not generalize to other populations. CONCLUSIONS: Provider perceptions aligned with patient values on amputation level but varied around the importance of each outcome. IMPLICATIONS: These findings illuminate some differences between patients' values and provider perceptions of patient values, suggesting a role for shared decision-making. Embedding this MCDA framework into a future decision aid may facilitate these discussions.

Perceived shared decision-making among patients undergoing lower-limb amputation and their care teams: A qualitative study.

BACKGROUND: Shared decision-making (SDM) is increasingly advocated in the care of vascular surgery patients. The goal of this investigation was to gain a greater understanding of the patient and provider experience of SDM during clinical decision-making around the need for lower-extremity amputation and amputation level related to chronic limb-threatening ischemia (CLTI) in the Veterans Health Administration. METHODS: Semistructured interviews in male Veterans with CLTI, vascular surgeons, physical medicine and rehabilitation physicians, and podiatric surgeons. Interviews were analyzed using team-based content analysis to identify themes related to amputation-level decisions. RESULTS: We interviewed 22 patients and 21 surgeons and physicians and identified 4 themes related to SDM: (1) providers recognize the importance of incorporating patient preferences into amputation-level decisions and strive to do so; (2) patients do not perceive that they are included as equal partners in decisions around amputation or amputation level; (3) providers perceive several obstacles to including patients in amputation level decisions; and (4) patients describe facilitators to their involvement in SDM. CONCLUSIONS: Despite the recognized importance SDM in amputation decision-making, patients often perceived that their opinion was not solicited. This may result from provider perception of significant challenges to SDM posed by the clinical context of amputation. Patients identified key features that might enhance SDM including presentation of clear, concise information, and the importance of communicating concern during the discussion. These findings point to gaps in the provision of patient-centric care through SDM discussions at the time of amputation.

Mortality Conversations Between Male Veterans and Their Providers Prior to Dysvascular Lower Extremity Amputation.

BACKGROUND: Among patients facing lower extremity amputation due to dysvascular disease, the mortality risk is very high. Given this, as well as the importance of a patient-centered approach to medical care, informing patients about their possible risk of dying may be important during preoperative shared decision-making. The goal of this investigation was to gain an understanding of patient and provider experiences discussing mortality within the context of amputation within the Veterans Health Administration. METHODS: Semistructured interviews were performed with Veterans with peripheral arterial disease and/or diabetes, vascular and podiatric surgeons, and physical medicine and rehabilitation physicians. Interviews were analyzed using team-based content analysis to identify themes related to amputation-level decisions. RESULTS: We interviewed 22 patients and 21 surgeons and physicians and identified 3 themes related to conversations around mortality: (1) both patients and providers report that mortality conversations are not common prior to amputation; (2) while most providers find value in mortality conversations, some express concerns around engaging in these discussions with patients; and (3) some patients perceive mortality conversations as unnecessary, but many are open to engaging in the conversation. CONCLUSIONS: Providers may benefit from introducing the topic with patients, including providing the context for why mortality conversations may be valuable, with the understanding that patients can always decline to participate should they not be interested or comfortable discussing this issue.

AMPREDICT PROsthetics-Predicting Prosthesis Mobility to Aid in Prosthetic Prescription and Rehabilitation Planning.

OBJECTIVE: To develop and validate a patient-specific multivariable prediction model that uses variables readily available in the electronic medical record to predict 12-month mobility at the time of initial post-amputation prosthetic prescription. The prediction model is designed for patients who have undergone their initial transtibial (TT) or transfemoral (TF) amputation because of complications of diabetes and/or peripheral artery disease. DESIGN: Multi-methodology cohort study that identified patients retrospectively through a large Veteran's Affairs (VA) dataset then prospectively collected their patient-reported mobility. SETTING: The VA Corporate Data Warehouse, the National Prosthetics Patient Database, participant mailings, and phone calls. PARTICIPANTS: Three-hundred fifty-seven veterans who underwent an incident dysvascular TT or TF amputation and received a qualifying lower limb prosthesis between March 1, 2018, and November 30, 2020 (N=357). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: The Amputee Single Item Mobility Measure (AMPSIMM) was divided into a 4-category outcome to predict wheelchair mobility (0-2), and household (3), basic community (4), or advanced community ambulation (5-6). RESULTS: Multinomial logistic lasso regression, a machine learning methodology designed to select variables that most contribute to prediction while controlling for overfitting, led to a final model including 23 predictors of the 4-category AMPSIMM outcome that effectively discriminates household ambulation from basic community ambulation and from advanced community ambulation-levels of key clinical importance when estimating future prosthetic demands. The overall model performance was modest as it did not discriminate wheelchair from household mobility as effectively. CONCLUSIONS: The AMPREDICT PROsthetics model can assist providers in estimating individual patients' future mobility at the time of prosthetic prescription, thereby aiding in the formulation of appropriate mobility goals, as well as facilitating the prescription of a prosthetic device that is most appropriate for anticipated functional goals.

The Development and Pilot Study of a Multiple Criteria Decision Analysis (MCDA) to Compare Patient and Provider Priorities around Amputation-Level Outcomes.

Background. Patients with chronic limb-threatening ischemia who are facing a lower-limb amputation often require a transmetatarsal amputation (TMA) or a transtibial amputation (TTA). A TMA preserves more of the patient's limb and may provide better mobility but has a lower probability of primary wound healing relative to a TTA and may result in additional amputation surgeries. Understanding the differences in how patients and providers prioritize key outcomes may enhance the amputation decisional process. Purpose. To develop and pilot test a multiple criteria decision analysis (MCDA) tool to elicit patient values around amputation-level selection and compare those with provider perceptions of patient values. Methods. We conducted literature reviews to identify and measure the performance of criteria important to patients. Because the quantitative literature was sparse, we developed a Sheffield elicitation framework exercise to elicit criteria performance from subject matter experts. We piloted our MCDA among patients and providers to understand tool acceptability and preliminarily assess differences in patient and provider priorities. Results. Five criteria of importance were identified: ability to walk, healing after amputation surgery, rehabilitation intensity, limb length, and prosthetic/orthotic device ease. Patients and providers successfully completed the MCDA and identified challenges in doing so. We propose potential solutions to these challenges. The results of the pilot test suggest differences in patient and provider outcome priorities. Limitations. The pilot test study enrolled a small sample of providers and patients. Conclusions. We successfully implemented the pilot study to patients and providers, received helpful feedback, and identified solutions to improve the tool. Implications. Once modified, our MCDA tool will be suitable for wider rollout. Highlights: Patients and providers have successfully completed our MCDA, and patients feel the MCDA may be useful in clinical practice.We encountered several methodologic challenges and identified approaches to ease participant burden.When data are sparse, using the Sheffield elicitation framework is helpful in creating a performance matrix, although patients relied largely on their amputation experiences to complete the exercise. Blinding the alternatives may help patients better understand the process.

Understanding the experience of veterans who require lower limb amputation in the veterans health administration.

PURPOSE: There is limited qualitative research on the experience of patients undergoing lower limb amputation due to chronic limb threatening ischemia (CLTI) and their participation in amputation-level decisions. This study was performed to understand patient lived experiences related to amputation and patient involvement in shared decision making. MATERIALS AND METHODS: Phenomenological interviews were conducted with Veterans 6-12 months post transtibial or transmetatarsal amputation due to CLTI. Interviews were read and summarized by two analysts who discussed the contents of each interview and relationships between interviews to identify emergent, cross-cutting elements of patient experience. RESULTS: Twelve patients were interviewed between March and August 2019. Three cross cutting elements of patient lived experience and participation in shared decision making were identified: 1) Lacking a sense of decision making; 2) Actively working towards recovery as response to a perceived loss of independence; and 3) Experiencing amputation as a Veteran. CONCLUSIONS: Patients did not report a high level of involvement in shared decision making about their amputation or amputation level. Understanding patient experiences and priorities is crucial to supporting shared decision making for Veterans with amputation due to CLTI.

The Development and Usability of the AMPREDICT Decision Support Tool: A Mixed Methods Study.

OBJECTIVE: Amputation level decision making in patients with chronic limb threatening ischaemia is challenging. Currently, evidence relies on published average population risks rather than individual patient risks. The result is significant variation in the distribution of amputation levels across health systems, geographical regions, and time. Clinical decision support has been shown to enhance decision making, especially complex decision making. The goal of this study was to translate the previously validated AMPREDICT prediction models by developing and testing the usability of the AMPREDICT Decision Support Tool (DST), a novel, web based, clinical DST that calculates individual one year post-operative risk of death, re-amputation, and probability of achieving independent mobility by amputation level. METHODS: A mixed methods approach was used. Previously validated prediction models were translated into a web based DST with additional content and format developed by an expert panel. Tool usability was assessed using the Post-Study System Usability Questionnaire (PSSUQ; a 16 item scale with scores ranging from 1 to 7, where lower scores indicate greater usability) by 10 clinician end users from diverse specialties, sex, geography, and clinical experience. Think aloud, semi-structured, qualitative interviews evaluated the AMPREDICT DST's look and feel, user friendliness, readability, functionality, and potential implementation challenges. RESULTS: The PSSUQ overall and subscale scores were favourable, with a mean overall total score of 1.57 (standard deviation [SD] 0.69) and a range from 1.00 to 3.21. The potential clinical utility of the DST included (1) assistance in counselling patients on amputation level decisions, (2) setting outcome expectations, and (3) use as a tool in the academic environment to facilitate understanding of factors that contribute to various outcome risks. CONCLUSION: After extensive iterative development and testing, the AMPREDICT DST was found to demonstrate strong usability characteristics and clinical relevance. Further evaluation will benefit from integration into an electronic health record with assessment of its impact on physician and patient shared amputation level decision making.

Organizing for thoughtful food: a meshwork approach.

This paper provides an alternative narrative for organizing food systems. It introduces meshwork as a novel theoretical lens to examine the ontological assumptions underlying the shadow and informal dynamics of organizing food. Through a longitudinal qualitative case study, we place relationality and becoming at the centre of organizing food and food systems, demonstrating how entangled relationships can create a complex ontology through the meshwork knots, threads and weave. We show how issues of collective concern come together to form dynamic knots of interactions, how the threads within the meshwork indicate processes of movement, and how the weave suggests degrees of food system resilience-but always in flow. This theoretical approach thus provides a platform for addressing thoughtful concerns about "food matters" including the integrity of our global food system, the negative health and environmental impacts of industrialized food production, and food safety issues.

A Prospective Longitudinal Study of Trajectories of Depressive Symptoms After Dysvascular Amputation.

OBJECTIVES: Characterize the course of depressive symptoms during the first year after dysvascular amputation and identify factors that predict symptom trajectories. DESIGN: Prospective cohort study of individuals undergoing lower extremity amputation (LEA), surveyed at 4 time points (perioperative period, 6 weeks, 4 months, and 12 months postamputation). Multilevel modeling was used to describe and predict trajectories. SETTING: Four Veterans Affairs medical centers, a university hospital, and a level I trauma center. PARTICIPANTS: Participants (N=141; 74% retention) were a consecutive sample, eligible if they were undergoing their first unilateral LEA secondary to dysvascular disease. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: Patient Health Questionnaire-9. RESULTS: Approximately 40% of participants endorsed at least moderate depressive symptoms at perioperative baseline. Individuals with greater depressive symptoms in the perioperative period concurrently reported greater pain, poorer self-rated health, and prior mental health treatment. In the first 6 weeks after amputation there was a substantial improvement in depressive symptoms, especially among individuals with greater symptoms at baseline. Depressive symptoms were generally stable after 6 weeks. None of the covariates assessed significantly predicted trajectories of depressive symptom improvement. CONCLUSIONS: Watchful waiting may be the most appropriate course of action for many patients in the first 6 weeks after amputation. After 6 weeks, however, symptom levels tend to stabilize, suggesting that active intervention is called for if patients remain depressed at this point. Some patients may benefit from more proactive intervention, such as those with prior mental health treatment histories.

Quality of Relationships With Caregivers, Depression, and Life Satisfaction After Dysvascular Lower Extremity Amputation.

OBJECTIVE: To describe the relationship between caregiver-specific support and conflict, and psychosocial outcomes among individuals experiencing their first dysvascular lower extremity amputation (LEA). DESIGN: Cross-sectional cohort study using self-report surveys. SETTING: Department of Veterans Affairs, academic medical center, and level I trauma center. PARTICIPANTS: Individuals undergoing their first major LEA because of complications of peripheral arterial disease (PAD) or diabetes who have a caregiver and completed measures of caregiver support and conflict (N=137; 94.9% men). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The Patient Health Questionnaire-9 to assess depression and the Satisfaction With Life Scale to assess life satisfaction. RESULTS: In multiple regression analyses, controlling for global levels of perceived support, self-rated health, age, and mobility, caregiver-specific support was found to be associated with higher levels of life satisfaction and caregiver-specific conflict was found to be associated with lower levels of life satisfaction and higher levels of depressive symptoms. CONCLUSIONS: The specific relationship between individuals with limb loss and their caregivers may be an important determinant of well-being. Conflict with caregivers, which has received little attention thus far in the limb loss literature, appears to play a particularly important role. Individuals with limb loss may benefit from interventions with their caregivers that both enhance support and reduce conflict.

A Longitudinal Study of Social Participation After Dysvascular Lower Extremity Amputation.

OBJECTIVE: This study examined patterns of social participation among individuals experiencing their first dysvascular lower extremity amputation. We identified the types of social participation valued by this population and explored factors that were associated with individuals' levels of participation and their subjective satisfaction with participation. DESIGN: A prospective cohort was recruited from four Veterans Administration Medical Centers and followed for 1 yr after amputation. Social participation was measured with a modified version of the Community Integration Questionnaire. Potential correlates included the Patient Health Questionnaire-9, Modified Social Support Survey, Locomotor Capability Index 5, Short Portable Mental Status Questionnaire, and self-rated health. RESULTS: At 1-yr postamputation, participants indicated that the most valued aspects of social participation were maintaining close friendships, visiting loved ones, and managing finances. Levels of social participation and satisfaction with participation were modest at 1-yr postamputation. Higher levels of social participation at 1 yr were related to better baseline mental status, better premorbid mobility, and lower amputation level. Higher satisfaction with participation was related to greater baseline social support. CONCLUSIONS: Individuals' social participation may be influenced by physical and cognitive factors, whereas their satisfaction with participation may be influenced by psychosocial factors. Rehabilitation specialists are encouraged to address both aspects of social participation when formulating and pursuing rehabilitation goals.

Communication networks of men facing a diagnosis of prostate cancer.

AIMS AND OBJECTIVES: This study seeks to identify the factors that shape the communication networks of men who face a potential diagnosis of prostate cancer, and how these factors relate to their disclosure about their changing health status. BACKGROUND: Men facing a potential diagnosis of prostate cancer are in a challenging situation; the support benefits of disclosing their changing health status to others in their communication networks is set against a backdrop of the potential stigma and uncertainty of the diagnosis. DESIGN: All men on a prostate biopsy waiting list were eligible for inclusion in an exploratory and interpretive study. METHODS: Semi-structured interviews with 40 men explored their network structures and disclosure of health information. Thematic analysis highlighted the factors which contributed to their network structures and their disclosure about their health status. RESULTS: Four network factors shaped men's perspectives about disclosing their health status: (1) tie strength, comprising both strong and weak ties; (2) knowledgeable others, with a focus on medical professionals in the family; (3) homophily, which included other individuals with a similar medical condition; and (4) geographical proximity, with a preference for face-to-face communication. CONCLUSION: Communication networks influence men's disclosure of their health status and in particular weak ties with medical knowledge have an important role. Men who use the potential for support in their networks may experience improved psychosocial outcomes. RELEVANCE TO CLINICAL PRACTICE: Using these four network factors-tie strength, knowledgeable others, homophily or geographical proximity-to forecast men's willingness to disclose helps identify men who lack potential support and so are at risk of poor psychosocial health. Those with few strong ties or knowledgeable others in their networks may be in the at-risk cohort. The support provided in communication networks complements formal medical care from nurses and other health professionals, and encouraging patients to use their communication networks improves the psychosocial health of the men themselves, their partners and their families.

Sexual activity after dysvascular lower extremity amputation.

OBJECTIVE: This study examined the prevalence and correlates of sexual activity among individuals experiencing their first dysvascular lower extremity amputation. DESIGN: A prospective cohort was recruited from 4 Veterans Affairs Medical Centers. Of 198 potential participants who met inclusion criteria, 113 (57%) agreed to participate within 7 days of amputation (baseline) and 6 weeks, 4 months, and 12 months post-amputation; 105 completed the sexual activity items at baseline. Measures included self-reported frequency of sexual activity; desire for more or less sexual activity; importance of sexual activity to satisfaction with life; Patient Health Questionnaire-9; Locomotor Capability Index-5; pain intensity/frequency; quality of life. RESULTS: Depending on the time period post-amputation, 11%-24% reported engaging in any sexual activity, although a majority indicated that sexual activity is very important to their satisfaction with life. Frequency of sexual activity increased between 6 weeks and 4 and 12 months post-amputation. In univariate analyses, older age was associated with decreased sexual activity at all time points; at 4 and 12 months, greater mobility was associated with increased sexual activity. In multivariable models, mobility was associated with sexual activity at 4 and 12 months; age and race remained associated with sexual activity at 4 and 12 months, respectively. At all time points, frequency and importance of sexual activity were significantly associated with one another. CONCLUSIONS: Although a minority of individuals engaged in any sexual activity during the study period, it remained an important factor in overall satisfaction with life. Younger age and improved mobility were associated with increased sexual activity. Rehabilitation specialists are encouraged to address sexuality and, if relevant, incorporate it into rehabilitation goals. (PsycINFO Database Record

Suicidal ideation among individuals with dysvascular lower extremity amputation.

OBJECTIVE: To examine the estimated prevalence and correlates of suicidal ideation (SI) among individuals 1 year after a first lower extremity amputation (LEA). DESIGN: Cohort survey. SETTING: Four medical centers. PARTICIPANTS: A referred sample of patients (N=239), primarily men, undergoing their first LEA because of complications of diabetes mellitus or peripheral arterial disease, were screened for participation between 2005 and 2008. Of these patients, 136 (57%) met study criteria and 87 (64%) enrolled; 70 (80.5%) of the enrolled patients had complete data regarding SI at 12-month follow-up. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: SI, demographic/health information, depressive symptoms, mobility, independence in activities of daily living (ADL), satisfaction with mobility and ADL, medical comorbidities, social support, self-efficacy. RESULTS: At 12 months postamputation, 11 subjects (15.71%) reported SI; of these, 3 (27.3%) screened negative for depression. Lower mobility, lower satisfaction with mobility, greater impairment in ADL, lower satisfaction with ADL, lower self-efficacy, and depressive symptoms were all correlated with the presence of SI at a univariate level; of these, only depressive symptoms remained significantly associated with SI in a multivariable model. CONCLUSIONS: SI was common among those with recent LEA. Several aspects of an amputee's clinical presentation, such as physical functioning, satisfaction with functioning, and self-efficacy, were associated with SI, although depression severity was the best risk marker. A subset of the sample endorsed SI in the absence of a positive depression screen. Brief screening for depression that includes assessment of SI is recommended.

Relationship between cognition and functional outcomes after dysvascular lower extremity amputation: a prospective study.

OBJECTIVE: The aim of this study was to examine associations between a cognitive screen and four neuropsychologic tests administered at both 6 wks and 4 mos after amputation and five functional outcomes measured 12 mos after lower extremity amputation. DESIGN: This study includes a prospective cohort from four medical centers. Participants were primarily male Veterans experiencing their first lower extremity amputation as a result of complications of diabetes mellitus or peripheral arterial disease. Of those eligible, 87 (64%) enrolled; 75 (86%) were retained at 12 mos. Measures included demographic/health information, four neuropsychologic measures, the Locomotor Capability Index-5, the Gronigen Activity Restriction Scale, prosthetic use, community participation, and social integration. RESULTS: Better performance on the Short Portable Mental Status Questionnaire at 4 mos was associated with greater 12-mo mobility and social integration. Better attention and working memory abilities 6 wks after amputation were associated with increased 12-mo prosthetic wear; and at 4 mos after amputation, with greater 12-mo mobility. Better verbal memory at 6 wks was associated with greater 12-mo social integration and community participation as well as increased prosthetic wear. CONCLUSIONS: These findings highlight the potential value in including a brief, formal cognitive assessment in addition to a general mental status screen. Specific domains of cognitive function are differentially associated with functional outcomes and may inform amputation rehabilitation decisions.

The role of expectations in pain after dysvascular lower extremity amputation.

OBJECTIVE: The objective was to determine the relationship between pain expectations assessed prior to surgery and satisfaction with pain 4 and 12 months after major dysvascular lower extremity amputation. RESEARCH METHOD: The study included a prospective cohort of male (n = 19) veterans experiencing their first lower extremity amputation due to complications of diabetes mellitus or peripheral arterial disease. Measures included presurgical expectations of pain at 4 and 12 months postamputation, actual average pain and satisfaction with pain at 4 and 12 months postamputation, and agreement between expected and actual pain. RESULTS: Sixty-eight percent of participants expected to experience no or minimal pain at 4 months; 95% expected to experience no or minimal pain at 12 months. Thirty-two percent and 58% of participants had more pain than they expected at 4 and 12 months, respectively. Participants whose pain expectations were met reported higher satisfaction with their actual level of pain at 12 months postamputation, even after adjusting for current pain levels. CONCLUSION: The results underscore the potential value of fostering realistic expectations about the degree to which amputation may impact average pain.
