Looking Upstream: Factors Shaping the Demand for Postacute Joint Replacement Rehabilitation

Tian W, DeJong G, Brown M, Hsieh C-H, Zamfirov ZP, Horn SD. Looking upstream: factors shaping the demand for postacute joint replacement rehabilitation.Since 1993, the numbers of hip and knee replacements in the United States have increased 2-fold to 3-fold while lengths of stay in acute care have decreased by about half, leading to a significant growth in the use of postacute rehabilitative care for patients with a joint replacement. To document these trends, this article uses secondary analysis of acute hospital discharge survey data and evaluates projections to 2030. This article uses a market approach to identify 3 sets of factors that influence the use of joint replacements: (1) increasing patient demand, (2) increasing supply of practitioners, and (3) the role of fiscal intermediaries. The article reviews underlying epidemiologic trends, growing numbers of orthopedic surgeons performing the procedure, technologic innovations, changing indications for the procedure, changing payer mix, and the effects of payer attempts to contain joint replacement costs. An unintended effect of Medicare payment policy has been to shift costs from acute care to downstream postacute care. Medicare and private health plan reimbursement policies need to take into account this broader perspective and not examine joint replacement care and payment in isolated care settings. Future research and health policy needs to consider the interdependent features of the health care system by linking changes in postacute care with upstream changes both in society at large and in the organization, delivery, and financing of acute care associated with joint replacement.     

Joint Replacement Rehabilitation Outcomes on Discharge From Skilled Nursing Facilities and Inpatient Rehabilitation Facilities

DeJong G, Horn SD, Smout RJ, Tian W, Putman K, Gassaway J. Joint replacement rehabilitation outcomes on discharge from skilled nursing facilities and inpatient rehabilitation facilities.

Objective

To compare functional outcomes at discharge across postacute settings.

Design

Prospective observational cohort study.

Setting

Eleven inpatient rehabilitation facilities (IRFs), 8 freestanding skilled nursing facilities (SNFs), and 1 hospital-based SNF from across the United States.

Participants

Consecutively enrolled patients (N=2152): patients with knee replacement (n=1401) and patients with hip replacement (n=751).

Interventions

None; examination of existing practice patterns.

Main Outcome Measure

FIM discharge motor score.

Results

Freestanding SNF patients entered with higher motor FIM scores and left with higher scores than did IRF patients. IRF patients, however, achieved larger motor FIM gains and achieved them in a shorter time. In multivariate models controlling for patient differences and onset days, IRFs were associated with better discharge motor outcomes, but the overall setting effect was not large. The largest motor FIM differences were between medium-volume IRFs and low-volume freestanding SNFs: 4.6 motor FIM points for patients with knee replacement and 7.3 motor FIM points for patients with hip replacement. Other differences between settings were much smaller. Multivariate models explained between a third and a half of the variance in outcome.

Conclusions

As a group, IRFs had better motor FIM outcomes than did SNFs, but the size of the IRF advantage was not large. Other important facility and practice characteristics also were associated with discharge outcomes after joint replacement rehabilitation. Earlier and more intensive rehabilitation was associated with better outcomes. The volume of joint replacement patients seen by a facility also plays a part: medium-volume facilities among both SNFs and IRFs had better outcomes.     

Recovery of gait after short-stay total hip arthroplasty

OBJECTIVE: To describe recovery of gait after total hip arthroplasty (THA) based on the assessment of spatiotemporal gait parameters determined with an ambulatory system. DESIGN: A 6-month inception cohort study. SETTING: Inpatient and outpatient setting in an academic hospital. PARTICIPANTS: Sixty-three patients participating in a short-stay program for THA. INTERVENTION: Primary unilateral THA. MAIN OUTCOME MEASURES: Walking speed, step length, step duration, and variability coefficient assessed at different walking speeds while performing an additional cognitive task and an endurance test. All measures were obtained preoperatively and 6 weeks and 6 months postoperatively. RESULTS: Patients improved significantly over time; however, extent and speed of recovery of gait parameters differed for each test part. The relation between walking speed and step length showed systematic improvement when analyzed over a range of speeds. At 6 months, the variability coefficient of the additional task test part was comparable with the preferred walking variability coefficient. The endurance test results could be predicted from the results of preferred walking. CONCLUSIONS: Assessment of recovery of gait function requires more than only assessment of "normal" walking. Particularly, an analysis of walking at different speeds and walking while performing an additional cognitive task demonstrate different aspects of gait recovery after THA.     

Biofeedback Training for Partial Weight Bearing in Patients After Total Hip Arthroplasty

Pataky Z, De León Rodriguez D, Golay A, Assal M, Assal J-P, Hauert C-A. Biofeedback training for partial weight bearing in patients after total hip arthroplasty.

Objective

To evaluate a new biofeedback training method based on visual delivery of information in patients after total hip arthroplasty (THA).

Design

Intervention study with prepost design.

Setting

Hospitalized care in a university referral center.

Participants

Patients (N=11) (age 56.1±9.0y) shortly after THA.

Intervention

A mobile system has been used for biofeedback training with the predefined partial weight bearing (PWB) threshold of 20kg. After the learning period, 4 retention tests, consisting of 3 successive walking cycles without feedback, were recorded for each patient: (1) acquisition test, (2) early retention test (after 30min), (3) the day after, and (4) after 2 days.

Main Outcome Measure

The pressure error and the maximum pressure force at each step before and after biofeedback training.

Results

A significant difference of pressure errors between the beginning and the end of the learning period has been measured (42.5±22.5N vs 3.7±11.4N, P<.001). However, there was no difference between the beginning of the learning period and different retention tests (after 30 minutes, after 1 day, after 2 days). In terms of maximal pressure force, there was a difference between the beginning and the end of learning (251N vs 195N, P<.05). The retention tests did not show significant differences compared with the baseline values.

Conclusions

THA patients were able to use the defined PWB during a short period of time and shortly after stopping the training; both the pressure errors and the maximal pressure force attended the values before training. These results confirm the difficulties to achieve PWB in patients after THA.     

髋关节翻修术中冰冻病理切片与99Tcm三相同位素骨扫描共用诊断髋关节假体周围感染

背景：常规血清学、影像学和实验室诊断方法诊断假体周围感染难以达到理想的灵敏度、特异度和准确性。尤其对于假体置换后晚期假体低毒性感染性松动和无菌性松动之间的鉴别诊断还缺乏普遍接受的诊断标准。术前、术中和术后多种诊断方法的联合运用对于明确感染诊断和制定手术翻修策略有重要的临床意义。目的：通过初次髋关节置换后翻修术前和术中联合运用99Tcm三相同位素骨扫描和冰冻病理切片多形核白细胞计数方法诊断髋关节假体周围感染,并与常规诊断手段相比较。方法：2008年4月至2013年5月共收治44例髋关节置换后翻修病例,结合临床症状和血清学检查指标,18例患者血沉和C-反应蛋白增高诊断为临床怀疑感染病例组;26例血清学指标正常诊断为临床怀疑无菌性松动病例组。所有患者翻修前进行99Tcm三相同位素骨扫描检查,同时结合翻修手术过程中组织冰冻病理切片结果。如两项结果均为阴性,诊断为假体无菌性松动,行一期翻修手术;反之则诊断为假体周围感染,行二期手术翻修。通过术后临床随访血清学指标及手术疗效,采用受试者工作曲线的统计学方法评估联合运用99Tcm三相同位素骨扫描和组织冰冻病理切片的诊断价值。结果与结论：18例临床感染病例组中16例患者术前99Tcm三相同位素骨扫描结果和术中冰冻病理结果均为阳性,诊断为感染,二期翻修;2例结果均阴性,排除感染,一期翻修。26例松动病例组中,25例术前99Tcm三相同位素骨扫描结果和术中冰冻病理结果阴性,诊断为无菌性松动,一期翻修;1例患者术后病原菌微生物学培养送检3个标本中1个标本培养出金黄色葡萄球菌,诊断为假体周围感染,仍采取一期翻修。增加99Tcm三相同位素骨扫描和冰冻病理切片多形核白细胞计数的方法后,工作特征曲线面?     

滑膜切除对全膝关节置换治疗骨性关节炎的影响

目的探讨全膝关节置换术（TKR）治疗骨性关节炎时同时行滑膜切除术对术后失血及临床结果的影响。方法选取符合骨性关节炎诊断标准并拟行单侧TKR的病人374例,随机分为两组,观察组192例,TKR时切除滑膜;对照组182例,TKR时保留滑膜。测定并比较两组术后引流量、输血率,计算隐性失血量;采用疼痛视觉模拟评分（VAS）和膝关节协会临床评分及功能评分（KSS）比较两组治疗效果。结果术前两组病人各项指标差异均无统计学意义（P〉0.05）。术后24h引流量、隐性失血量观察组明显高于对照组,差异有显著性（t=2.137、2.238,P〈0.05）,两组输血率差异无显著性（P〉0.05）。两组术后24h、3d及4周VAS差异无显著性（P〉0.05）。两组术后4周、12个月KSS差异无显著性（P〉0.05）。术后12、24个月时两组KSS、浮髌试验阳性率差异均无显著性（P〉0.05）。结论 TKR治疗骨性关节炎同时切除滑膜会增加术后出血,但对远期临床结果无明显影响。     

连续髂筋膜阻滞和硬膜外阻滞下行全髋置换后镇痛的比较

背景：硬膜外持续镇痛曾被认为是下肢术后镇痛的金标准,其效果确切,全身不良反应较少,临床上普遍采用。但此法有低血压及尿潴留等不良反应,且患者在术后常规需应用低分子肝素抗凝,有增加硬膜外血肿的可能性,限制了硬膜外镇痛的临床使用。目前超声引导下连续髂筋膜腔隙阻滞技术的相关研究报道甚少。 目的：评价连续髂筋膜间隙阻滞和连续硬膜外阻滞两种不同镇痛方法对全髋关节置换后镇痛效果和关节功能恢复的影响。 方法：将60例择期行全髋关节置换患者分为2组：连续髂筋膜间隙阻滞组和连续硬膜外镇痛组（n=30）。两组患者在全身麻醉诱导前均接受预注量,连续髂筋膜间隙阻滞组经髂筋膜间隙注入0.25%罗哌卡因30 mL,连续硬膜外阻滞组经硬膜外导管注入0.20%罗哌卡因10 mL,均留置导管。待镇痛效果明确后,全麻插管。术毕两组分别经髂筋膜间隙、硬膜外连接镇痛泵持续给药,未使用术后自控镇痛单次给药。若疼痛难以忍受时,视其疼痛程度,予补救镇痛（帕瑞昔布20-40 mg/次）。记录目测类比评分、帕瑞昔布补救剂量、麻醉并发症、髋关节Harris评分、下床时间和住院时间。 结果与结论：目测类比评分、额外追加的镇痛药量、Harris 评分、住院日两组无明显差别。但是下床时间连续髂筋膜间隙阻滞组早于连续硬膜外阻滞组,而且连续髂筋膜间隙阻滞组并发症明显低于连续硬膜外阻滞组。提示全髋关节置换后,两种镇痛方式均可提供满意的术后镇痛效果,髋关节功能可得到良好的恢复;但连续髂筋膜间隙阻滞并发症少且有利于患者早期下床活动,对于髋关节置换后镇痛是更好的选择。     

Outcomes after metal-on-metal hip resurfacing: could we achieve better function?

Newman MA, Barker KL, Pandit H, Murray DW. Outcomes after metal-on-metal hip resurfacing: could we achieve better function?

Objective

To report functional outcomes after metal-on-metal (MOM) hip resurfacing.

Design

A cohort of 126 MOM hip resurfacing operations were reviewed 1 year after surgery.

Setting

Hospital trust specializing in orthopedic surgery.

Participants

Sixty-seven right and 59 left hips were reviewed in patients (N=120; 71 men, 49 women; mean age, 56±9y; range, 24-76y).

Interventions

Not applicable.

Main Outcome Measures

Administered once at follow-up. Function was measured using the Oxford Hip Score (OHS), Hip disability and Osteoarthritis Outcome Score, and UCLA Activity Score. Complications, pain, range of motion, Trendelenburg test, strength, walking, single-leg stand, stair climbing, and 10-m walk time were assessed.

Results

Overall examination was satisfactory with few complications. High functional levels were reported. The median OHS was 15 and median UCLA Activity Score 7 (active). For 25%, outcome was poor with persistent pain, reduced hip flexion (mean, 94.46°±12.7°), decreased strength (P<.001), restricted walking, and functional limitations.

Conclusions

Information about outcomes is important for patients undergoing surgery. Hip resurfacing remains an emergent technology, with further follow-up and investigation warranted. One explanation for suboptimal recovery may be current rehabilitation, originally developed after total hip arthroplasty. Rehabilitation tailored to hip resurfacing, paced for this active population and progressed to higher demand activities, may improve outcomes.     

Outcomes after inpatient rehabilitation of primary and revision total hip arthroplasty

OBJECTIVE: To compare the outcomes of patients who have gone to inpatient rehabilitation after primary total hip arthroplasty (THA) and revision THA. DESIGN: Retrospective, comparative study. SETTING: Fifty-bed freestanding, university-affiliated rehabilitation hospital. PARTICIPANTS: Two hundred fifty-five male and female primary THA patients and 147 male and female revision THA patients. INTERVENTION: Interdisciplinary inpatient rehabilitation. MAIN OUTCOME MEASURES: Length of stay (LOS), FIM instrument score and FIM motor score components, hospital charges, and discharge disposition location. RESULTS: FIM scores improved from admission to discharge by 29.7 and 27.9 points for the primary THA and revision THA groups, respectively (P<.05). LOS was shorter for primary THA patients compared with revision THA patients (10.0d vs 11.5d, P<.05). FIM efficiency (DeltaFIM/LOS) was greater for primary THA compared with revision THA (3.4 and 2.7 points/day, P<.05). Total rehabilitation hospital charges were 11,421 US dollars and 13,707 US dollars for the primary and revision THA groups, respectively, with the mechanical and infection revision THAs incurring the greatest charges (14,596 US dollars and 15,386 US dollars, respectively; P<.001). Compared with primary THA, revision THA patients were twice as likely to be discharged to locations other than home. CONCLUSIONS: FIM score improvement was lower and LOS and hospital charges were greater in revision THA than in primary THA after rehabilitation. Infection revision THA patients gained less functional independence and were discharged home less often than mechanical or pain revision THA patients; finally, infection and mechanical revision THA accrued the highest hospital charges.
