Nuclei have smooth contours and an evenly distributed insomnia in teens discount 25 mg unisom with visa, ﬁnely granular chromatin pattern insomnia ios 511 unisom 25mg fast delivery. Preparation-Speciﬁc Criteria In liquid-based preparations insomnia lyrics audien 25mg unisom with amex, lower uterine segment and directly sampled endome trium tends to exhibit small dense cellular groups containing only epithelium or stroma (Fig insomnia 54 gaming festival discount 25 mg unisom amex. In conventional preparations sleep aid mouth guard buy 25 mg unisom, large cellular groups may have a “stretched” conﬁguration and glands and blood vessels are more commonly noted (Fig insomnia 26 weeks pregnant order unisom 25mg mastercard. Endometrial stromal cells adherent to blood ves sels and ﬂattened against the slide in a fanlike pattern 2. Direct endometrial sam pling can occasionally be present in women with an intact cervix secondary to the vigorous use of an endocervical brush or broom sampling device. Directly sampled endometrial tissue may mimic glandular neoplastic abnormali ties or rarely high-grade squamous lesions due to the presence of hyperchromatic crowded groups with nuclear crowding, nuclear overlap, and high nucleus to cyto plasmic ratios. In contrast to spontaneously exfoliated endometrial cells, direct brushing of endometrial tissue may yield large cellular fragments that can recapitu late their native in situ architecture (so-called organoid differentiation). This appear ance may include branching tubular glands amid stroma composed of round to spindle-shaped cells. The low-power recogni tion of branching glands and glandular-stromal complexes can avoid confusion with ritagoreti26@gmail. In liquid-based preparations, smaller rounded groups may have only one visible component. The most helpful clues in this situation are small nuclear size (approximating that of an intermediate nucleus); smooth, regular nuclear contours; and evenly distributed chromatin. In addition, groups of endometrial stromal cells may contain small vessels that pro trude from the surface of the organoid groups, a feature not seen in neoplastic epi thelial abnormalities. The mean nuclear area is larger than that of the intermediate cell and similar to the parabasal cell at 50 μm. The nuclear to cytoplasmic ratio is variable, and in this instance, it approaches one to one. Squamous metaplastic cells can exhibit a spectrum of morphology from relatively undifferentiated small round cells to highly differentiated intermediate/superﬁcial squamous cells. In metaplasia, stimuli such as infection, inﬂammation, or other type of trauma cause an alteration in the pathway of development of new cells replacing those lost by wear and tear. Routine screening from a 27-year-old woman, day 8 of menstrual cycle shows reactive metaplastic cells with “spidery” cytoplasmic processes, a feature that is seen more often in conventional smears. The metaplastic surface epithelium may eventually become indistinguishable from other squamous mucosa; however, the histologic ﬁnding of glandular spaces ﬁlled by endocervical or metaplastic squamous cells beneath the surface is a marker of the cervical transformation zone and an indication that the overlying epithelium was once glandular (Fig. One of the most difﬁcult tasks in day-to-day cytologic practice is the evalua tion of metaplastic cells, especially those with high nuclear to cytoplasmic ratios. Nuclear enlargement without other nuclear abnormalities in squamous metaplas tic cells should lead to cautious evaluation, so as not to overinterpret the sample. A nuclear to cytoplasmic ratio of less than 50 %, smooth nuclear contours, and even distribution of chromatin all favor benign squamous metaplasia (Fig. A variety of stimuli can trigger an altered pathway of differentiation in the stem cell population that was committed to generating endocervical cells. The cells underneath the mucus secreting epithelial cells have rounded up, lost their ability to secrete mucin, and assumed a protective role, increasing the thickness of barrier between the stimulus and the underlying tis sue. This cohesive group of cells also shows some modest nucleolar prominence that is consistent with reactive/reparative changes 2. Both of these processes lead to hypermaturation of the native squamous epithelium, more closely approximating the normal appearance of skin. Keratotic changes can be considered a second-order protective reaction for subepithelial tissues with metaplasia being the ﬁrst-order reaction. These terms are not speciﬁcally listed in Bethesda terminology due to lack of consensus deﬁnitions. Although some cytologists may choose to include such terms to describe a morpho logic feature that may correlate with leukoplakia on colposcopy, they should not be used as an interpretive category in cytology reports. After metaplastic conversion, continued trauma may lead to formation of cyto plasmic keratohyaline granules (Fig. Intermediate squamous cells showing prominent cytoplasmic keratohyaline granules, a precursor to full keratinization Fig. Both are examples of “typical parakeratosis” showing miniature squamous cells with small bland, pyknotic nuclei ritagoreti26@gmail. Cells may be seen in isolation, in sheets, or in whorls; cell shape may be round, oval, polygonal, or spindle shaped. Nuclei are small (approximately 10 μm2 in cross-sectional area) and dense (pyknotic). Miniature squamous cells with small pyknotic nuclei and orangeophilic to eosinophilic cytoplasm (“parakeratosis”) are a nonneoplas tic reactive cellular change. However, single cells or cell clusters that demonstrate pleomorphism of nuclear shape and/or increased nuclear size and/or chromasia (“atypical parakeratosis,” “dyskeratosis,” or “pleomorphic parakeratosis”) are rep resentative of an epithelial cell abnormality. Anucleate, but otherwise unremarkable mature, squamous cells (“hyperkerato sis”) constitute a nonneoplastic cellular change. Inadvertent contamination of the specimen with vulvar material may also introduce anucleate squamous cells into the cervical cytology specimen. When extensive hyperkeratosis is present, an underly ing neoplastic or nonneoplastic process may be associated and should be considered when evaluating such cytologic preparations [15]. Thick plaques of pleomorphic anucleate squamous cells with irregular contours may rarely be the only clue to an underlying squamous cell carcinoma [16]. Similar to parakeratosis, hyperkeratosis alone does not constitute a speciﬁc interpretive category. This metaplastic epithelium includes several cell types (ciliated cells, peg cells, and goblet cells) [17] (Fig. Tubal metapalsia is a frequent ﬁnding in the upper endocervical canal/lower uterine segment. Nuclei are round to oval and may be enlarged, pleomorphic, and often hyperchromatic. The ciliated cells of tubal metaplasia show prominent terminal bars at the base of the cilia ritagoreti26@gmail. Tubal metaplasia shows prominent pseudostratiﬁcation and can have enlarged nuclei that make it a look-alike for endocervical adenocarcinoma in situ Fig. A goblet cell is seen at the center with its nucleus closer to the top of the image (arrow) Presence of cilia and/or terminal bars is characteristic, but single ciliated cells in isolation are not sufﬁcient for the designation. This is due to the tendency toward enlarged nuclei, crowded nuclei, and nuclear stratiﬁcation. The cervical squamous epithelium is remarkably thinned and made up entirely of parabasal cells. Generalized nuclear enlargement may occur with a slight increase in nuclear to cytoplasmic ratio. Intermediate cells tend to be normochromatic, but parabasal-type cells may have mild hyperchromasia and tend to have more elongated nuclei. An abundant inﬂammatory exudate and basophilic granular background that resem bles tumor diathesis may be present in examples of extreme atrophy (atrophic vaginitis) (Figs. Note ﬂat, monolayer sheet of parabasal-type cells, with preserved nuclear polarity Fig. Note the classic ﬁnding of granular debris in background, degenerating parabasal cells, and polymorphonuclear leukocytes. In liquid-based preparations, the granular debris is often clumped and adheres to atrophic cell clusters in a pattern that may mimic “clinging tumor diathesis” (see Fig. Attention to cellular features is crucial to avoid overinterpretation Globular collections of basophilic amorphous material (blue blobs) reﬂect either degenerated parabasal cells or inspissated mucus. Degenerated orangeophilic or eosinophilic parabasal cells with nuclear pyknosis resembling “parakeratotic” cells may be present (“pseudoparakeratosis”) (Fig. Histiocytes varying in size and shape and containing multiple, round to epithelioid nuclei and foamy or dense cytoplasm may be seen (Fig. Preparation-Speciﬁc Criteria Liquid-Based Preparations: Less nuclear enlargement than in conventional preparations due to immediate ﬁxa tion, rounding up, and a lack of ﬂattening on the slide. Granular background material tends to clump rather than be dispersed, yielding a “cleaner” background (Fig. Note more dissociation of parabasal cells in a relatively clean background Conventional Preparations: Air-drying artifact may result in more prominent cellular enlargement. The degree of atrophic change is thus highly variable, reﬂecting the differing levels of hormonal support that may be present. Cytomorphology can range from intermedi ate cell predominant to parabasal predominant to deeply atrophic (atrophic vagini tis) patterns in postmenopausal women. These differences may reﬂect alternate sources of endogenous estrogen or the presence of exogenous estrogenic substances. In addi tion, atrophy may coexist with dysplasia or neoplasia, and the diffusely increased ritagoreti26@gmail. Multinucleated histiocytic giant cells are a nonspeciﬁc ﬁnding and are often seen in postmenopausal and postpartum specimens. In postmenopausal and postpartum states, multinucleated histiocytes (giant cells) are often found in cervical samples associated with chronic inﬂammatory processes [19] (Fig. In association with this pattern, a particular appearance of the intermediate squamous cell showing prominent glycogen with a ﬂattened “boatlike” appearance is com mon. When progesterone secre tion is prolonged (as in pregnancy), the navicular cells have greatly thickened borders and can form dense clusters (Fig. These cells are derived from hormonally stimulated endocervical or endometrial stroma. On the upper right (histology, H&E) is the corresponding histology showing decidual change. Other multinucleated cells that can be seen in cervical cytology include multinucleated histiocytes in postmenopausal and postpartum women and cells infected with herpes virus ritagoreti26@gmail. Cytoplasm is abundant, granular, or ﬁnely vacuolated and there may be cytoplasmic processes. They may resemble small squamous metaplastic or endometrial cells, as well as high-grade squamous intraepithelial lesion cells. When recognized, the background often has either ﬁndings of exodus or other elements of pregnancy. Cells are small with enlarged nuclei, high nuclear to cytoplasmic ratios, and hyper chromasia. They can be identiﬁed in cervical cytology specimens in late pregnancy and postpartum periods. Nuclei are normochromatic with even chromatin distribution but often have irregu lar nuclear contours. The histology (c, right, H&E) demon strates the exuberant variation in epithelial nuclear morphology due to hormonal stimulation dur ing pregnancy in nonpregnant hormonally stimulated individuals. In histologic specimens, Arias-Stella reaction manifests as pleomorphism of size and shape in glandular cell nuclei, often with bizarre forms, in association with a characteristic smudgy chromatin pattern. Nuclei are large, hyperchromatic with contour irregularities (grooves and pseudoin clusions), and granular to smudgy chromatin. It is important to be aware of the patient’s pregnant or postpartum status to avoid overinterpretation of these ﬁndings. In addition, increased glycogenation can result in cytoplasmic clearing in intermediate (navicular) cells that may mimic koilocytic change; however, the clearing due to glycogenation is typi cally diffuse, involving all or most of the cell, and lacks the sharp “cookie cut ter” edges of koilocyte vacuoles (See Figs. More importantly, the cells lack nuclear atypia, necessary for the interpretation of a squamous preneoplastic abnormality. Reactive glandular cell alterations are also com monly encountered in cervical cytology specimens from pregnant women and have features similar to reactive/reparative endocervical alterations from other causes. However, at low magniﬁcation, these cells are typically larger than dysplastic squa mous cells, particularly those of high-grade lesions. Additionally, the nuclear con tours are typically smooth, the chromatin is ﬁnely granular and evenly distributed, and nucleoli are usually prominent [20, 21]. Syncytiotrophoblast is most likely to be mistaken for herpes infection, but the nuclei lack the ground-glass inclusions seen in herpetic cytopathic effect and show some heterochromatin. The tapering of the cytoplasm at one end (where the cell was attached to the placenta) and “bunching up” of nuclei may be helpful in distinguishing syncytiotrophoblast from other multinu cleated cells. Mild hyperchromasia may be present, but the chromatin structure and distribution remain uniformly ﬁnely granular (Fig. Cytoplasm may show polychromasia, vacuolization, or perinuclear halos but with out peripheral thickening (Figs. Enlarged cells often form cohesive sheets that interdigitate in a classic “school of ﬁsh” architecture or may be mechanically distorted by sampling and elongate to form “taffy pull” cytoplasmic appendages (Figs. Preparation-Speciﬁc Criteria Liquid-Based Preparations: Both squamous and endocervical reparative groups are more rounded and three dimensional and thus darker due to light having to pass through more cytoplas mic and nuclear material. The edges of cells are better ﬁxed and show less streaming relative to conventional preparations (Fig. Conventional Preparations: Reparative changes may be more pronounced as cells ﬂatten out against the slide. This size variability can range from the normal area of squamous or endocervical cell nuclei to markedly enlarged, often within the same cellular ritagoreti26@gmail. Variation in nuclear size, prominent nucleoli, and rare intracytoplas mic polymorphonuclear leukocytes are seen; these features are consistent with endocervical repair. Endocervical cells show variable increase in nuclear size, prominent nucleoli, and ﬁne chromatin. Squamous cells show mild nuclear enlargement with nuclear hypochromasia, perinuclear halos, and cytoplasmic polychromasia result ing in a “moth-eaten” appearance. Examples of reactive perinuclear halos induced by organisms/inﬂammation such as seen in trichomonas infection.

Selection of an endoscopic approach should be tailored to patient selection, surgeon ability, and equipment ability. The surgeon should take into consideration how the procedure may be performed cost-efectively with the fewest complications. Do not perform routine oophorectomy in premenopausal women undergoing hysterectomy for non-malignant indications who are at low risk for ovarian cancer. The long-term risks associated with salpingo-oophorectomy are most pronounced in women who are younger than 45–50 years who were not treated with estrogen. Do not routinely administer prophylactic antibiotics in low-risk laparoscopic procedures. Although the appropriate use of antibiotic prophylaxis for hysterectomy is high, antibiotics are increasingly being administered to women who are less likely to receive beneft. The potential results are signifcant resource use and facilitation of antimicrobial resistance. Avoid the unaided removal of endometrial polyps without direct visualization when hysteroscopic guidance is available and can be safely performed. Though conservative management may be appropriate in some patients, hysteroscopic polypectomy is the mainstay of treatment. Removal without the aid of direct visualization should be avoided due to its low sensitivity and negative predictive value of successful removal compared to hysteroscopy and guided biopsy. Avoid opioid misuse in the chronic pelvic pain patient without compromising care through education, responsible opioid prescribing and advocacy. Providers must also educate and screen for risk factors for opioid misuse and follow patients on chronic opioid therapy for any signs of misuse. Patients with any specifc questions about the items on this list or their individual situation should consult their physicians. The subcommittee of expert surgeons in the feld of minimally invasive surgery recommended and developed a more efective use of health care resources, along with safe techniques to practice.

Can We Rely on Blind Endometrial Biopsy for Detection of Focal Intrauterine Pathology? Strong evidence exists that artifcial nutrition does not prolong life or improve quality of life in patients with advanced dementia. Substantial functional 1 decline and recurrent or progressive medical illnesses may indicate that a patient who is not eating is unlikely to obtain any signifcant or long-term beneft from artifcial nutrition. Feeding tubes are often placed after hospitalization, frequently with concerns for aspirations, and for those who are not eating. Contrary to what many people think, tube feeding does not ensure the patient’s comfort or reduce sufering; it may cause fuid overload, diarrhea, abdominal pain, local complications, less human interaction and may increase the risk of aspiration. Assistance with oral feeding is an evidence-based approach to provide nutrition for patients with advanced dementia and feeding problems. Don’t obtain a urine culture unless there are clear signs and symptoms that localize to the urinary tract. In this situation, it is reasonable to obtain a urine culture if there are objective signs of systemic infection such as fever (increase in temperature of equal to or greater than 2°F [1. Careful diferentiation of cause of the symptoms (physical or neurological versus psychiatric, psychological) may help better defne appropriate 4 treatment options. The therapeutic goal of the use of antipsychotic medications is to treat patients who present an imminent threat of harm to self or others, or are in extreme distress – not to treat nonspecifc agitation or other forms of lesser distress. Released September 4, 2013 (Items 1 – 5), Released March 20, 2015 (items 6–10), Recommendation #8 updated July 2, 2015 Don’t routinely prescribe lipid-lowering medications in individuals with a limited life expectancy. In fact, studies show that elderly patients with the lowest cholesterol have the highest mortality after adjusting other risk factors. In addition, a less favorable risk-beneft ratio may be seen for patients older than 85, where benefts may be more diminished and risks from statin drugs more increased (cognitive impairment, falls, neuropathy and muscle damage). Appropriate indications for indwelling urinary catheter placement include acute retention or outlet obstruction, to assist in healing of deep sacral or perineal wounds in patients with urinary incontinence, and to provide comfort at the end of life if needed. Don’t recommend screening for breast, colorectal or prostate cancer if life expectancy is estimated to be less than 10 years. Benefts of cancer screening occur only after a lag time of 10 years (colorectal or breast cancer) or more (prostate cancer). Patients with a life expectancy shorter than this lag time are less likely to beneft from screening. Prostate cancer screening by prostate-specifc antigen testing is not recommended for asymptomatic patients because of a lack of life-expectancy beneft. False positive “test-of-cure” specimens may complicate clinical care and result in additional courses of inappropriate anti-C. Don’t recommend aggressive or hospital-level care for a frail elder without a clear understanding of the individual’s goals of care and the possible benefts and burdens. Hospital-level care has known risks, including delirium, infections, side efects of medications and treatments, disturbance of sleep, and loss of mobility and function. Therefore, for some frail elders, the balance of benefts and harms of hospital-level care may be unfavorable. To avoid unnecessary hospitalizations, care providers should engage in advance care planning by defning goals of care for the patient and discussing the risks and benefts of various interventions, including hospitalization, in the context of prognosis, preferences, indications, and the balance of risks and benefts. Patients who opt for less-aggressive treatment options are less likely to be subjected to unnecessary, unpleasant and invasive interventions and the risks of hospitalization. Using a reliable, representative method of taking blood pressures with special attention to orthostatic hypotension is important, as orthostatic hypotension has been associated with increased mortality and cardiovascular events. In addition, moderate or high-intensity treatment of hypertension has been associated with an increased risk of serious falls and injury in frail older adults. Suggested elements were considered for appropriateness, relevance to the core of the specialty and opportunities to improve patient care. They were further refned to maximize impact and eliminate overlap, and then ranked in order of potential importance both for the specialty and for the public. A literature search was conducted to provide supporting evidence or refute the activities. The list was modifed and a second round of selection of the refned list was sent to the workgroup for paring down to the fnal “top fve” list. Statements were phrased as specifc overuse statements by using the word “don’t,” thereby refecting the action necessary to improve the value of care.

Acceptance and adoption: Because tasimelteon is the only drug approved to treat non-24 sleep aid during pregnancy buy discount unisom online, clinicians are likely to accept it sleep aid queintrine order unisom 25mg amex, experts thought insomnia toronto buy 25mg unisom mastercard. Its positive safety profile and low potential for abuse may contribute to clinicians’ acceptance insomnia zippy buy 25 mg unisom fast delivery, experts said sleep aid toddler buy unisom 25mg otc. One research expert thought clinician acceptance may be limited because of the length of time sleep aid ingredients discount unisom. For patients who have third-party payer coverage for tasimelteon, acceptance is likely to be high, experts stated. Health care delivery infrastructure and patient management: Little to no impact will be evident in health care delivery infrastructure and patient management, experts agreed, because tasimelteon is an oral drug taken at home. A research expert noted that the additional monitoring for 378 weeks or months to see an effect may have a small impact on patient management. The high cost of tasimelteon is likely to be the largest impact factor, experts concurred, especially among third party payers that are providing coverage. One clinical expert suggested that limited total health care resources mean that payers that weigh the overall societal benefit could limit drug coverage to more 381 severe cases. Health disparities: Health disparities may increase due to the drug’s high cost and uneven coverage from third-party payers, experts agreed, which may limit access for some patients, especially the economically disadvantaged. Patients who use tasimelteon may experience reduced 380 disparities related to quality of life, a health systems expert speculated. Wheelchair users can experience pressure ulcers, osteoporosis, depression, and cardiovascular, respiratory, urinary, and gastrointestinal adverse events associated with confinement to power-assisted devices. To address these issues in a home or community setting, a wearable, battery-powered exoskeleton has been developed to enable select patients with paraplegia to “walk” upright. Intervention: the ReWalk Personal exoskeleton is a wearable, battery-powered exoskeleton with motorized leg braces and crutches for support. The device uses a tilt sensor near the chest to propel the motorized leg braces when patients shift their body weight. The onboard computer and rechargeable batteries are contained in a waist pack; the most recent version (6. The ReWalk system weighs about 35 lb and 384,385 is activated by a controller on a wrist band. The ReWalk system is designed to mimic a natural walking gait and functional speed (up to 1. The system can be used on multiple surfaces and terrains for indoor and outdoor use. It can be used for 4 hours 384,386 of continuous walking (generally one day of use) and recharged overnight. However, patients must be 386 160–190 cm tall (5 feet, 3 inches to 6 feet, 3 inches) and weigh less than 100 kg (220 lb). Patients must have sufficient bone density, flexibility, and cardiovascular health, as determined by a physician’s exam. Although patients control the exoskeleton, trained caregivers must be present to 382 assist during use of the device, even during home use. It is intended for daily, personal use by 385 patients with paraplegia who complete device training at a rehabilitation or training center. A significant potential safety issue with wearable exoskeletons is a computer problem or other device malfunction that puts the user at risk of harm in certain environments or situations. However, a trained caregiver 382 must be with a patient using the exoskeleton and could aid in these scenarios. Patients are also at risk for pressure sores, bruising or abrasions, falls and associated injuries, and diastolic 387 hypertension during use. Clinical trials: Two studies are ongoing to evaluate the ReWalk Personal in community and 388,389 home settings. One study reported in 2012 that all patients (n=12) were able to transfer to the exoskeleton and walk with it independently for 5–10 minutes. All patients made positive comments about emotional and psychosocial benefits, and some patients reported improvements in pain, bowel 390 and bladder function, and spasticity. Another study of 6 patients from 2012 reported that no 391 adverse safety events occurred and that the system was well tolerated. A study published in 2015, after experts commented on this intervention, reported that 10 of 60 candidates (17%) were enrolled and 5 (8%) completed the training program. Primary reasons that candidates were not enrolled included ineligibility (24) and lack of interest in a 10-week training program (16). Walking speeds were faster and walking distances were longer in all exoskeleton users than in individuals not using 49 the device; subjects indicated the exoskeleton did not generally meet their high expectations in 392 terms of hoped-for benefits. Wearable exoskeletons are expected to be used by patients with paraplegia who retain use of their hands and shoulders, can stand using crutches, have good bone density, and have good cardiovascular health. Patients using the equipment need to be comfortable using a computer controlled device and undergoing extensive training in a rehabilitation facility. The technology is contraindicated for people who have a history of neurologic injuries other than spinal cord injury, severe spasticity, significant contractures, unstable spine, unhealed limb or pelvic fractures, or other severe 387 concurrent medical issues. Patients using the systems require extensive training on a ReWalk Rehabilitation unit with rehabilitation specialists before they can purchase a ReWalk Personal. Patients must also be trained how to troubleshoot or compensate for possible malfunctions that occur while using the device. A trained caregiver, such as a family member or home health aide, assists when patients use the 387 device. Diffusion and cost: the manufacturer states that it sold 25 ReWalk systems (both ReWalk Rehabilitation for institutional use and ReWalk Personal systems) in the first half of 2015 and 31 in 393,394 the last quarter of 2014; it is unclear how many were ReWalk Personal systems. The manufacturer stated that diffusion is limited by the time it takes to evaluate and train patients and 393 395 process reimbursement claims. Medicare Part B may cover exoskeletons as durable medical equipment for beneficiaries whose physician has prescribed it for home use. If a durable medical equipment supplier does not accept direct Medicare reimbursement, Medicare cannot limit the amount a supplier can charge. These suppliers cannot charge patients more than 20% coinsurance and any unmet yearly deductible for any equipment or supplies included in 396 the competitive bidding program. Our searches of 11 representative, private, third-party payers that publish their coverage policies online found 8 policies pertaining to the ReWalk Personal exoskeleton. Clinical Pathway at Point of this Intervention Acute spinal cord injury requires immediate medical attention. A physician completes a physical exam, including neurologic exam, to identify the location of the injury. Magnetic resonance 405 imaging, computerized tomography, or spine radiography may be ordered. Emergency treatment of a spinal cord injury involves immobilizing the spine as gently and quickly as possible. Acute treatment includes maintaining breathing, preventing shock, immobilizing the neck, and avoiding 405 possible complications. Ongoing treatment such as physical therapy, occupational therapy, or other rehabilitation therapies, 406 as well as muscle spasticity medications may be needed. Powered wheelchairs for patients with paraplegia can be controlled with a joystick. Other devices that provide upright support, such as stationary standers, compete with exoskeletons to provide benefits associated with upright weight-bearing postures. Overall high-impact potential: wearable, battery-powered exoskeleton (ReWalk Personal) to enable mobility in community or home settings in patients with paraplegia Overall, experts commenting on this intervention agreed that an unmet need exists for a mobility and upright-standing device. An exoskeleton for community or home use may prevent complications associated with prolonged wheelchair use, the experts agreed. They suggested the high cost will have the most effect on patient acceptance and access, possibly contributing to health disparities. Results and Discussion of Comments Six experts, with clinical, research, and health systems backgrounds, provided perspectives on 407-412 this intervention. Unmet need and health outcomes: An alternative to prolonged wheelchair use, associated with functional limitations and health complications, is an important unmet need for patients with paraplegia, the experts agreed. The exoskeleton may potentially improve mobility; independence; pain, bowel and bladder function; spasticity; bone density; and skin integrity, experts speculated, although they also conceded that more studies are needed. Acceptance and adoption: Experts were split over how readily clinicians may accept the exoskeleton for patients with paraplegia. Clinicians who are slow to adopt may point to other options, fall risks, costs, and the amount of training required by staff and patients as reasons for abstaining, experts said. Alternatively, some clinicians may believe the benefits of improved mobility, independence, and quality of life outweigh the risks and recommend consideration of the device, experts suggested. Patients are likely to be guided by their physicians’ views of the exoskeleton and are initially limited to using it in a rehabilitation setting, thus requiring clinician 411,412 buy-in for training before using the exoskeleton in a home setting, two clinical experts stated. Patients who are highly motivated to walk, who can commit to intensive training, and who can afford the device may readily adopt the exoskeleton, experts noted. Health care delivery infrastructure and patient management: Health care delivery infrastructure is likely to be minimally impacted by use of the exoskeleton, experts agreed. The biggest impact will be in the additional training needed for physical therapists, biomedical engineers, and other staff, experts noted. Patient management may also be impacted by the amount of training needed for patients and caregivers in rehabilitation and home settings, experts concurred. Patients and third-party payers may face substantial costs because of the high price of the exoskeleton and a need to replace it every 5 years, experts stated. A clinical expert suggested any overall effects would be 411 limited because the patient population is small. An expert with a research perspective speculated that any controversies over costs may be minimal because many in the affected population are likely 410 combat veterans. Health disparities: Health disparities may increase because of the high cost of the exoskeleton, all experts agreed. A clinical expert noted that patients must pay for 20% of the cost of durable 412 medical equipment that is covered by Medicare, which may be prohibitive for some. Two experts mentioned that additional training and maintenance of the device may be required, adding to costs 407,410 that may affect access. Patients do not have options that provide natural movement, intuitive controls, or tactile 413 sensations. Whether the features of this arm will be available in a commercially 414,415 produced prosthesis is unclear. The device has a metallic external structure with no exposed mechanics, does not require a fabric sleeve, and is dust and water resistant. The entire arm is resistant to light rain, and 415 the fingers up to the base can be immersed in water. An audible vibration indicates when the mode changes between hand and arm, when 414 it moves in or out of standby, and when grip mode or grip pressure is changed. It can be used only by patients who have limb loss at the shoulder joint, mid-upper arm, or mid-lower arm— 416 not at the elbow or wrist. The humeral and shoulder configurations can accommodate an internal 414,415 battery while all configurations can use an external battery worn on a belt or harness. The 415 internal battery has a run time of about 1 hour and the external battery, about 6 hours. The shoulder configuration has 10 powered degrees of freedom and additional passive degrees of freedom that allow for simultaneous, coordinated movement at the shoulder, humeral rotator, 414 elbow, forearm, wrist, thumb, index finger, or fingers three to five. The hand mode has six programmed grips for objects of various sizes and 415 shapes. The detent feature allows users to manipulate an object in the hand without losing the 415 415 grip on it. The shoulder configuration has an endpoint control system that uses software to coordinate joint movements to bring the end of the prosthesis into a desired position from one command instead of a 415 series of commands. A dynamic socket controller regulates inflatable bladders inside transhumeral sockets to stabilize the device and provide pressure relief. For example, the device is able to recognize when it is moving toward the head and reduce its speed to avoid a collision. It can 415 distinguish between intentional foot controls and walking, trips, or stumbles. In targeted muscle reinnervation, surgeons transfer nerve connections that once controlled a patient’s hand or 54 arm to remaining muscles. The procedure offers more intuitive control of a prosthesis because the nerves that once controlled the amputated limb control the reinnervated muscles. Signals from the transferred nerves are amplified by the reinnervated muscle and are more easily detected by surface 413 electrodes. Researchers further reported that patients rated satisfaction and 418 usability higher for the third-generation device than the second-generation device. A prospective, observational cohort study with 75 patients is ongoing to evaluate the change in quality of life while 419 using the device at home for 13 weeks. The system is not yet commercially available because the developer is seeking a partner to manufacture and commercialize the prosthesis. In an interview with the Boston Business Journal, the developer said the cost will depend on the number made, but would ideally be in the range of tens of 425 thousands of dollars. Medicare Part B covers artificial limbs as durable medical equipment for beneficiaries whose physician has prescribed it for home use. In certain geographic areas, Medicare’s competitive bidding program may be in effect, which means that Medicare pays for the equipment and related supplies only if they are obtained from contracted suppliers. These suppliers cannot charge patients more than 20% coinsurance and any unmet yearly deductible for any equipment or supplies 426 included in the competitive bidding program.
