Perioperative Opioid Counseling Reduces Opioid Use Following Primary Total Joint Arthroplasty.

Background: Preoperative counseling may reduce postoperative opioid requirements; however, there is a paucity of randomized controlled trials (RCTs) demonstrating efficacy. The purpose of this study was to perform an interventional, telehealth-based RCT evaluating the effect of peri-operative counseling on quantity and duration of opioid consumption following primary total joint arthroplasty (TJA). Methods: Participants were randomized into three groups: 1. Control group, no perioperative counseling; 2. Intervention group, preoperative educational video; 3. Intervention group, preoperative educational video and postoperative acceptance and commitment therapy (ACT). Opioid consumption was evaluated daily for 14 days and at 6 weeks postoperatively. Best-case and worse-case intention to treat analyses were performed to account for non-responses. Bonferroni corrections were applied. Results: 183 participants were analyzed (63 in Group 1, 55 in Group 2, and 65 in Group 3). At 2 weeks postoperatively, there was no difference in opioid consumption between Groups 1, 2, and 3 (p>0.05 for all). At 6 weeks postoperatively, Groups 2 and 3 had consumed significantly less opioids than Group 1 (p=0.04, p<0.001) (Table 1). Group 3 participants were less likely to obtain an opioid refill relative to Group 1 participants (p=0.04). Participants in groups 2 and 3 ceased opioid consumption a median of 6 days and 2 days sooner than Group 1, respectively (p<0.001, p=0.03) (Table 2). Conclusion: Perioperative opioid counseling significantly decreases the quantity and duration of opioid consumption at 6 weeks following primary TJA. Level of Evidence: I.

Automated Text-Messaging After Hip Arthroscopy: A Randomized-Controlled Trial of "Post-Op Buddy".

PURPOSE: To assess an automated text-messaging system for patients after hip arthroscopy and its impact at 90 days on the Hip Disability Osteoarthritis Outcome Score Physical Function Short form (HOOS-PS, HOOS-Pain), compliance with rehabilitation guidelines, and patient satisfaction. METHODS: One hundred twenty-one participants (average age 29 ± 8.7 years, 52% female) undergoing hip arthroscopy at 2 academic institutions were prospectively enrolled and randomized to receive (1) standard perioperative communication or (2) additional automated mobile phone text messages. Inclusion criteria included ability to communicate in written English and access to a mobile phone with text-messaging capability. Patients undergoing revision surgery or simultaneous femoral or acetabular osteotomy were excluded. HOOS-PS and HOOS-Pain were collected preoperatively, and after surgery an automated mobile phone robot sent participants in the therapeutic arm intermittent text messages for 90 days. At 90 days all participants again completed HOOS-PS, HOOS-Pain, and additional survey questions on satisfaction with their experience (10-point scale), communication from the surgical team (10-point scale) and adherence to physical therapy exercises, weight-bearing guidelines, and brace use, The primary outcome assessed was a statistically significant change in HOOS-PS and HOOS-Pain; secondary outcomes included change in satisfaction, communication, and adherence to physical therapy exercises, weightbearing guidelines, or brace use. Wilcoxon rank sum was used to compare HOOS-PS and HOOS-Pain scores at 0 and 90 days. Demographic characteristics and survey variables were compared using Students t test for continuous variables and χ2 or Fisher exact test for categorical variables as appropriate. RESULTS: There were statistically significant and clinically relevant improvements in HOOS-PS and HOOS-Pain in both groups (P < .05). Subjective feedback was strongly positive, with 96% of text message participants reporting they would choose automated messages if it was offered to them again in the future. CONCLUSIONS: Ninety days of automated text messaging after hip arthroscopy failed to show a significant difference in HOOS-PS (P = .09), HOOS-Pain (P = .13), patient-reported compliance with postoperative guidelines, or satisfaction with support and communication from the surgical team. LEVEL OF EVIDENCE: I, randomized control trial (RCT).

The Impact of Psychological Factors and Their Treatment on the Results of Total Knee Arthroplasty.

➤: There is a growing body of evidence implicating psychosocial factors, including anxiety, depression, kinesiophobia, central sensitization, and pain catastrophizing, as negative prognostic factors following total knee arthroplasty (TKA). ➤: Symptoms of anxiety and depression likely represent risk factors for negative outcomes in patients undergoing TKA. However, few studies have assessed the impact of preoperative interventions for these conditions on postoperative outcomes. ➤: The Tampa Scale of Kinesiophobia and the Central Sensitization Inventory have demonstrated value in the diagnosis of kinesiophobia and central sensitization. Higher preoperative indices of kinesiophobia and central sensitization predict worse patient-reported outcomes postoperatively. ➤: Although evidence is limited, cognitive-behavioral therapy for kinesiophobia and duloxetine for central sensitization may help to diminish the negative impact of these preoperative comorbidities. It is important to note, however, that outside the realm of TKA, cognitive-behavioral therapy has been recognized as a more effective treatment for central sensitization than medical treatment. ➤: Awareness of these issues will allow surgeons to better prepare patients regarding postoperative expectations in the setting of a comorbid psychosocial risk factor. Further research into the role of preoperative assessment and possible treatment of these conditions in patients undergoing TKA is warranted.

The Effect of the COVID-19 Pandemic on Hip and Knee Arthroplasty Patients in the United States: A Multicenter Update to the Previous Survey.

BACKGROUND: In March 2020, elective total hip and knee arthroplasty (THA and TKA) were suspended across the United States in response to the COVID-19 pandemic. We had previously published the results of a survey to the affected patients from 6 institutions. We now present the results of a larger distribution of this survey, through May and June 2020, to electively scheduled patients representing different regions of the United States. METHODS: Fifteen centers identified through the American Association of Hip and Knee Surgeons Research Committee participated in a survey study of THA and TKA patients. Patients scheduled for primary elective THA or TKA but canceled due to the COVID-19 elective surgery stoppage (3/2020-5/2020) were included in the study. Descriptive statistics along with subgroup analysis with Wilcoxon rank were performed. RESULTS: In total, surveys were distributed to 2135 patients and completed by 848 patients (40%) from 15 institutions. Most patients (728/848, 86%) had their surgery postponed or canceled by the surgeon or hospital. Unknown length of surgical delay remained the highest source of anxiety among survey participants. Male patients were more likely to be willing to proceed with surgery in spite of COVID-19. There were minimal regional differences in responses. Only 61 patients (7%) stated they will continue to delay surgery for fear of contracting COVID-19 while in the hospital. CONCLUSION: Similar to the previous study, the most anxiety-provoking thought was the uncertainty, over if and when the canceled joint replacement surgery could be rescheduled. Patients suffering from the daily pain of hip and knee arthritis who have been scheduled for elective arthroplasty remain eager to have their operation as soon as elective surgery is allowed to resume.

Preoperative Opioid Prescription Filling Is a Risk Factor for Prolonged Opioid Use After Elbow Arthroscopy.

PURPOSE: To (1) report the frequency of postoperative opioid prescriptions after elbow arthroscopy, (2) evaluate whether filling opioid prescriptions preoperatively placed patients at increased risk of requiring more opioid prescriptions after surgery, and (3) determine patient factors associated with postoperative opioid prescription needs. METHODS: A national claims-based database was queried for patients undergoing primary elbow arthroscopy. Patients with prior total elbow arthroplasty or septic arthritis of the elbow were excluded. Patients who filled at least 1 opioid prescription between 1 and 4 months prior to surgery were defined as the preoperative opioid-use group. Monthly relative risk ratios for filling an opioid prescription were calculated for the first year after surgery. Multiple logistic regression analysis was performed to identify factors associated with opioid use at 3, 6, 9, and 12 months after elbow arthroscopy, with P < .05 defined as significant. RESULTS: We identified 1,138 patients who underwent primary elbow arthroscopy. The preoperative opioid-use group consisted of 245 patients (21.5%), 61 of whom (24.9%) were still filling opioid prescriptions 12 months after surgery. The multivariate analysis determined that the preoperative opioid-use group was at increased risk of postoperative opioid prescription filling at 3 months (odds ratio [OR], 9.02; 95% confidence interval [CI], 5.98-13.76), 6 months (OR, 8.74; 95% CI, 5.57-13.92), 9 months (OR, 7.17; 95% CI, 4.57-11.39), and 12 months (OR, 6.27; 95% CI, 3.94-10.07) after elbow arthroscopy. Patients younger than 40 years exhibited a decreased risk of postoperative opioid prescription filling at 3 months (OR, 0.49; 95% CI, 0.25-0.91), 6 months (OR, 0.19; 95% CI, 0.06-0.50), 9 months (OR, 0.48; 95% CI, 0.22-0.97), and 12 months (OR, 0.44; 95% CI, 0.19-0.94) after surgery. CONCLUSIONS: Preoperative opioid filling, fibromyalgia, and psychiatric illness are associated with an increased risk of prolonged postoperative opioid after elbow arthroscopy. Patient age younger than 40 years and chronic obstructive pulmonary disease are associated with a decreased risk of postoperative opioid prescription filling within the first postoperative year. LEVEL OF EVIDENCE: Level III, retrospective cohort study.

The Effect of the COVID-19 Pandemic on Electively Scheduled Hip and Knee Arthroplasty Patients in the United States.

BACKGROUND: In response to the COVID-19 pandemic, hospitals in the United States were recommended to stop performing elective procedures. This stoppage has led to the cancellation of a large number of hip and knee arthroplasties. The effect of this on patients' physical mental and economic health is unknown. METHODS: A survey was developed by the AAHKS Research Committee to assess pain, anxiety, physical function, and economic ability of patients to undergo a delayed operation. Six institutions conducted the survey to 360 patients who had to have elective hip and knee arthroplasty cancelled between March and July of 2020. RESULTS: Patients were most anxious about the uncertainty of when their operation could be rescheduled. Although 85% of patients understood and agreed with the public health measures to curb infections, almost 90% of patients plan to reschedule as soon as possible. Age and geographic region of the patients affected their anxiety. Younger patients were more likely to have financial concerns and concerns about job security. Patients in the Northeast were more concerned about catching COVID-19 during a future hospitalization. CONCLUSIONS: Patients suffering from the pain of hip and knee arthritis continue to struggle with pain from their end-stage disease. They have anxiety about the COVID-19 pandemic. Few patients feel they will be limited financially and 90% want to have surgery as soon as possible. Age and physical location of the patients affect their causes for anxiety around their future surgery.

Postoperative care via smartphone following carpal tunnel release.

INTRODUCTION: This study explores a novel smartphone application for postoperative care following carpal tunnel release (CTR). We hypothesized that a software-based 'virtual visit' for CTR could be safe, effective and convenient for the patient. METHODS: Our group developed the software application utilized in this study. Interactive steps with video instructions enabled patients to complete dressing and suture removal, capture a wound photo, answer a question about median nerve symptoms and capture a video of finger range of motion. Adult patients undergoing endoscopic or open CTR were enrolled. Prior to their scheduled postoperative visit, patients received and completed the module using their smartphone. Agreement between findings of the virtual visit and the corresponding in-person clinical visit was assessed using kappa values. RESULTS: Twenty-two patients were contacted regarding study enrolment and 17 patients were enrolled (ages 23-63, mean 48.2, 6M, 11F). Of 16 patients who participated, all completed dressing removal. Ten of 16 patients removed their sutures successfully. Fourteen patients captured a clinically adequate wound photo and 15 patients answered a question about median nerve symptoms. Fourteen patients captured a range of motion video. Software assessments of surgical wounds, nerve symptoms and physical exams agreed strongly with clinical assessments. DISCUSSION: Most patients were able to respond to a question about their symptoms, provide clinical assessment of their wound via a photo and record a video of their range of motion. Suture removal was the most difficult task. More investigation is needed to determine which patients can reliably remove their sutures.

Mobile Phone Administration of Hip-Specific Patient-Reported Outcome Instruments Correlates Highly With In-office Administration.

INTRODUCTION: Patient-reported outcome (PRO) instruments typically are delivered via paper or computer; we validated administration of hip-specific instruments over a mobile phone software communication platform outside a clinical encounter. METHODS: Consecutive patients (n = 69) presenting to a hip preservation clinic completed the Hip Disability and Osteoarthritis Outcome Score Short Form physical function and pain subscales (HOOS-PS and HOOS-PAIN) using standard collection techniques. The subsequent day, patients completed these instruments via a text messaging software program. Text reminders were sent to encourage completion of unanswered questions. Correlation between in-office and mobile phone delivery of PROs was assessed. RESULTS: The intraclass correlation coefficient between in-clinic and mobile phone delivery of HOOS-PS and HOOS-PAIN was 0.72 (95% confidence interval, 0.58 to 0.81) and 0.80 (95% confidence interval, 0.69 to 0.87), respectively. Completion rate of 93% (64 of the 69) was observed using mobile phone and software messaging. Nine patients completed their PRO after being sent a text message reminder. Fifty-one percent of patients completed all PRO questions within 5 minutes; 26% took between 5 and 10 minutes, and 16% took 10 to 30 minutes for completion. DISCUSSION: HOOS-PS and HOOS-PAIN PRO instruments administered via text messaging with automated reminders demonstrate good to excellent reproducibility, no minimal detectable change between communication methods, and a high completion rate in adolescents and young adults with hip pain. Mobile phone delivery via automated software may be a valid method for administration of other PROs, allowing for communication with patients anytime and anywhere. LEVEL OF EVIDENCE: Level IV, case series.

Intraoperative Point of View Video Capture and Surgical Segmentation in Carpal Tunnel Release: A Feasibility Analysis.

OBJECTIVE: The purpose of this study was to (1) examine the feasibility of intraoperative point of view video while performing open and endoscopic carpal tunnel release (CTR), (2) define surgical segments of CTR, and (3) describe the duration of various surgical steps of open versus endoscopic CTR in a teaching setting. DESIGN: Fellowship trained hand surgeons reached consensus on surgical segments for CTR. Adult patients 18 and older previously indicated for CTR in clinic were eligible. Head-mounted point-of-view cameras were worn during endoscopic and open CTR by resident surgeons. Video was reviewed to determine segment duration. Independent sample t tests were used for comparison of duration by technique with statistical significance set as p < 0.05. SETTING: University of Iowa Hospitals and Clinics; 200 Hawkins Dr, Iowa City, IA 52242; Tertiary Academic Medical Center. PARTICIPANTS: Orthopedic Surgery Residents and Orthopedic Surgery Faculty. RESULTS: Surgical segments were defined as incision, dissection of superficial soft tissue structures, transection of the carpal ligament, and surgical incision closure. Twelve of 14 video capture events yielded data. In the teaching setting, the average duration of endoscopic CTR was 609.5 seconds (±111.07) versus 547.75 seconds (±82.06) for open with p value = 0.406. No surgical segments were significantly different. Transition time from dissection to ligament transection differed significantly (p = 0.004) between endoscopic (46.88 seconds ± 19.19) and open (9.0 seconds ± 7.90) CTR. Transition time between ligament transection and closure was significantly different (p = 0.029) among endoscopic (50.5 seconds ± 15.0) and open (26.25 seconds ± 2.99) CTR. CONCLUSIONS: Point-of-view video capture is feasible for the capture of video during a common hand surgery procedure. A method for managing device battery power is necessary for future applications. CTR can be defined as, and described in, individual procedure segments potentially useful for surgical education as well as efficiency improvements. Identification of surgical segments may aid the development of better objective tools for the assessment of surgeon skill and competency for common orthopedic procedures.

Prescription Opioid Use Before and After Hip Arthroscopy: A Caution to Prescribers.

PURPOSE: To determine pre- and postoperative opioid utilization while identifying risk factors for prolonged postoperative opioid use following hip arthroscopy. METHODS: All patients undergoing hip arthroscopy between 2007 and the second quarter of 2016 were identified within the Humana Inc. administrative claims database. Chronic preoperative opioid utilization was defined as filling of any opioid prescription 1 to 3 months before surgery, whereas acute preoperative opioid utilization was defined as filling any opioid prescription within 1 month of surgery. Rates of pre- and postoperative opioid utilization were calculated, and patient demographic characteristics and medical conditions associated with pre- and postoperative opioid utilization were identified. RESULTS: Of the 1,208 patients undergoing hip arthroscopy, chronic and acute preoperative opioid utilization was observed in 24.9% and 17.3% of patients, respectively. Chronic preoperative opioid utilization was more frequently observed in obese (P < .001) patients, those ≥50 years of age (P = .002), and those with preexisting anxiety and/or depression (P < .001). In multivariate analysis, chronic preoperative opioid utilization was the strongest predictor of opioid prescription filling at 3, 6, 9, and 12 months postoperatively (odds ratio at 3 months, 18.60, 95% confidence interval, 12.41 to 28.55), whereas preexisting anxiety and/or depression and obesity were additionally identified as predictors of prolonged postoperative opioid utilization. CONCLUSIONS: Chronic preoperative opioid utilization before hip arthroscopy is common at 24.9%. The high rate of chronic preoperative opioid utilization is particularly important considering that chronic preoperative opioid utilization is the strongest predictor of continued postoperative opioid prescription filling out to 12 months postoperatively. LEVEL OF EVIDENCE: Level IV, retrospective case series.

Increasing Perioperative Communication With Automated Mobile Phone Messaging in Total Joint Arthroplasty.

BACKGROUND: Automated mobile phone messaging has not been reported in total joint arthroplasty (TJA). Our purpose was to compare Press Ganey (PG) and Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) scores between TJA patients who did and did not receive perioperative automated mobile phone messages. METHODS: Patients were prospectively enrolled and received messages for 1 week prior until 2 weeks after TJA. Message content included reminders, activity, and pain control. Patients answered select PG/HCAHPS and questions regarding their experience with the automated communication platform. Average PG/HCAHPS scores were compared to historical TJA patients in the 3-year window prior (control group) with significance P < .05. RESULTS: Thirty-seven consecutive patients were approached and 92% (n = 34) were enrolled. The experimental group was 47% male, with 80% patients between 51 and 75 years. The experimental (n = 30) and control groups (n = 26) were similar. Patients receiving messages were more likely to have a good understanding of health responsibilities (P = .024) and feel that the care team demonstrated shared decision-making (P = .024). Of patients enrolled, 87% felt messages helped them be more prepared for surgery, 100% felt messages kept them better informed, and 97% would participate again. CONCLUSION: TJA patients who received perioperative communication via automated mobile phone messaging had improved patient satisfaction scores postoperatively. Patients perceived this form of communication was useful and kept them better informed. Automated mobile phone messaging can be an easily integrated, helpful adjunct to surgeons, healthcare systems, and case managers to more effectively communicate with patients undergoing TJA in this era of value-based care.

Delivery of Patient-Reported Outcome Instruments by Automated Mobile Phone Text Messaging.

BACKGROUND: Patient-reported outcome (PRO) instruments allow patients to interpret their health and are integral in evaluating orthopedic treatments and outcomes. The purpose of this study was to define: (1) correlation between PROs collected by automated delivery of text messages on mobile phones compared with paper delivery; and (2) patient use characteristics of a technology platform utilizing automated delivery of text messages on mobile phones. METHODS: Paper versions of the 12-Item Short Form Health Survey (SF-12) and the short form of the Disabilities of the Arm, Shoulder and Hand (QuickDASH) were completed by patients in orthopedic hand and upper extremity clinics. Over the next 48 hours, the same patients also completed the mobile phone portion of the study outside of the clinic which included text message delivery of the SF-12 and QuickDASH, assigned in a random order. Correlations between paper and text message delivery of the 2 PROs were assessed. RESULTS: Among 72 patients, the intraclass correlation coefficient (ICC) between the written and mobile phone delivery of QuickDASH was 0.91 (95% confidence interval [CI], 0.85-0.95). The ICC between the paper and mobile phone delivery of the SF-12 physical health composite score was 0.88 (95% CI, 0.79-0.93) and 0.86 (95% CI, 0.75-0.92) for the SF-12 mental health composite score. CONCLUSIONS: We find that text message delivery using mobile phones permits valid assessment of SF-12 and QuickDASH scores. The findings suggest that software-driven automated delivery of text communication to patients via mobile phones may be a valid method to obtain other PRO scores in orthopedic patients.

Patient-Reported Outcomes After Multiligament Knee Injury: MCL Repair Versus Reconstruction.

BACKGROUND: Management of the medial collateral ligament (MCL) in the setting of a multiligamentous knee injury (MLKI) represents an area of great controversy. PURPOSE: Our study was designed to compare long-term patient-reported outcomes (PROs) after MCL repair versus reconstruction in the setting of a multiligamentous injury of the knee. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: At a single institution, 68 patients were identified over a 10-year period as having MCL intervention in the setting of MLKI. Of these patients, 34 (50%) were successfully contacted via telephone to collect Lysholm and International Knee Documentation Committee (IKDC) scores. A retrospective chart review of these subjects was also conducted to identify patient and surgical factors affecting PROs. RESULTS: At a mean 6-year follow-up (range, 2-11 years), the mean Lysholm score was 77.4 ± 23.1 and mean IKDC score was 72.6 ± 23.6. Univariate analyses identified time to surgery (P = .005) and MCL reconstruction (P = .001) as risk factors for Lysholm score ≤75. Univariate analyses identified patient age (P = .049), time to surgery (P = .018), and MCL reconstruction (P = .004) as risk factors for IKDC score ≤75. On subsequent multivariate analysis, MCL reconstruction was found to be a predictor of Lysholm or IKDC score of ≤75. CONCLUSION: Patients undergoing MCL repair in the setting of MLKI generally had higher PROs than those undergoing reconstructions at a mean 6 years of follow-up. Further work is needed to elucidate patient and surgical factors that may influence subjective outcomes after multiligament knee injuries.

The AAHKS Clinical Research Award: What Are the Costs of Knee Osteoarthritis in the Year Prior to Total Knee Arthroplasty?

BACKGROUND: Despite American Academy of Orthopaedic Surgeons Clinical Practice Guidelines (CPGs) related to the non-arthroplasty management of osteoarthritis (OA) of the knee, non-recommended treatments remain in common use. We sought to determine the costs associated with non-arthroplasty management of knee OA in the year prior to total knee arthroplasty (TKA) and stratify them by CPG recommendation status. METHODS: The Humana database was reviewed from 2007 to 2015 for primary TKA patients. Costs for hyaluronic acid (HA) and corticosteroid injections, physical therapy, braces, wedge insoles, opioids, non-steroidal anti-inflammatories, and tramadol in the year prior to TKA were calculated. Cost was defined as reimbursement paid by the insurance provider. Costs were analyzed relative to the overall non-inpatient costs for knee OA and categorized based on CPG recommendations. RESULTS: In total 86,081 primary TKA patients were analyzed and 65.8% had at least one treatment in the year prior to TKA. Treatments analyzed made up 57.6% of the total non-inpatient cost of knee OA in the year prior to TKA. Only 3 of the 8 treatments studied have a strong recommendation for their use (physical therapy, non-steroidal anti-inflammatories, tramadol) and costs for these interventions represented 12.2% of non-inpatient knee OA cost. In contrast, 29.3% of the costs are due to HA injections alone, which are not supported by CPGs. CONCLUSION: In the year prior to TKA, over half of the non-inpatient costs associated with knee OA are from injections, therapy, prosthetics, and prescriptions. Approximately 30% of this is due to HA injections alone. If only interventions recommend by the CPG are utilized then costs associated with knee OA could be decreased by 45%.

Can We Predict Discharge Status After Total Joint Arthroplasty? A Calculator to Predict Home Discharge.

BACKGROUND: Postoperative discharge to a skilled nursing facility after total joint arthroplasty (TJA) is associated with increased costs, complications, and readmission. The purpose of this study was to identify the risk factors for discharge to a location other than home to build a calculator to predict discharge disposition after TJA. METHODS: The American College of Surgeons National Surgical Quality Improvement Program database was queried from 2011 to 2013 to identify patients who underwent primary total hip or total knee arthroplasty. Risk factors were compared between patients discharging home vs a facility. Predictors of facility discharge were converted to discrete values to develop a simple numerical calculator. RESULTS: After primary TJA, patients discharged to a facility were typically older (70.9 vs 64.3, P < .001), female (69.5% vs 55.7%, P < .001), had an elevated American Society of Anesthesiologist (ASA) class, and were more likely to be functionally dependent before surgery (3.8% vs 1.1%, P < .001). Patient age, preoperative functional status, nonelective THA for hip fracture, and ASA class were most predictive of facility discharge. After development of a predictive model, scores exceeding 40 and 80 points resulted in a facility discharge probability of 75% and 99%, respectively. CONCLUSION: In patients undergoing TJA, advanced age, elevated ASA class, and functionally dependent status before surgery strongly predicted facility discharge. Given that facility discharge imposes a significant cost and morbidity burden after TJA, patients, surgeons, and hospitals may use this simple calculator to target this susceptible patient population.

Single-incision robotic colectomy: are costs prohibitive?

BACKGROUND: The feasibility, safety, and costs of single-incision robotic colectomy (SIRC) are not known. METHODS: A retrospective review was conducted, comparing the initial 29 consecutive SIRC procedures performed to 36 multiport laparoscopic colectomies (MLC). RESULTS: The groups did not differ significantly on age, body mass index, gender, ASA classification, smoking status, steroid usage or rate of diabetes. Procedure time, conversion rate, infectious complications and length of stay did not differ significantly. The ratio of observed:expected direct hospital costs statistically favoured MLC, although there was no statistical difference between groups for contribution margin, or for observed and expected direct hospital costs. CONCLUSIONS: These results demonstrate safety and technical feasibility for SIRC in selected patients with short-term outcomes and hospital costs comparable to MLC. Contribution margin remained positive and expected costs exceeded observed for SIRC. Increased costs for SIRC are a concern. The comparable but relatively high mortality in both groups may represent an institutional approach to colectomy where significant comorbidity is not a contraindication to minimally invasive surgery.

Utilization of a text-messaging robot to assess intraday variation in concussion symptom severity scores.

OBJECTIVE: To determine the amount of within-day variation of Concussion Symptom Severity Scores (CSSSs) in athletes with a clinically diagnosed concussion. DESIGN: This prospective cohort study used a text-messaging robot to survey concussed athletes using the CSSS 5-times daily while they remained symptomatic. SETTING: Academic sports concussion clinic at a large tertiary care medical center. PARTICIPANTS: Fourteen 14- to 22-year-old athletes with clinically diagnosed concussions were enrolled. All were injured in sport, still in season, English speaking, and used a cellular telephone to text message on a regular basis. ASSESSMENT OF RISK FACTORS: This study did not collect any demographic or other information about the subjects. The only data collected were the individual responses to the questions in the Post Concussion Symptom Score (PCSS). The only aim of this study was to evaluate the variability in responses to the CSSS, which is calculated from the PCSS. MAIN OUTCOME MEASUREMENTS: The primary outcome measure was a repeatability coefficient from a random-effects model. Concussion Symptom Severity Score, mean daily CSSS, and standard deviation of CSSS differences from the mean were also calculated. RESULTS: Mean follow-up was 23.9 days. A total of 24 180 text messages were received from subjects. Eight hundred four complete surveys were analyzed. Repeatability coefficient was ±23.1. CONCLUSIONS: When surveyed frequently by a text-messaging robot, concussed athletes report poorly repeatable Sport Concussion Assessment Tool 2 (SCAT2) Symptom Severity Scores. CLINICAL RELEVANCE: The SCAT2 Symptom Severity Score may be an invalid method of tracking concussion severity and resolution over time.

Arthroscopic validation of the clinical exam for the detection of the symptomatic synovial-plical complex by relief from surgical excision.

PURPOSE: The goal is to introduce a reproducible exam technique that allows clinical diagnosis of symptomatic plical bands and associated synovium about the knee. We then aimed to assess the accuracy of the exam technique through arthroscopic confirmation of these tissues. Lastly, we hope to determine whether arthroscopic plicectomy and partial synovectomy is an effective treatment for alleviating the pain associated with symptomatic plica. METHODS: This retrospective study evaluated 80 consecutive symptomatic knees under the care of a single physician diagnosed with symptomatic plica and associated painful synovium from 2001-2011. These patients underwent diagnostic and therapeutic arthroscopy to verify the presence of a plica and painful synovium with plicectomy and partial synovectomy if necessary. Statistical analysis was performed to determine the sensitivity and positive predictive value of the exam. RESULTS: The medial parapatellar region was the most common location for symptomatic plica and associated synovial tissue. The exam technique described in this study had a sensitivity of 83.8% with a positive predictive value of 98.6% in the specific patient population described. CONCLUSIONS: This study suggests that while the medial plical band is the most common, there is frequently sensitive synovial tissue found in multiple locations about the knee. This study also suggests that a thorough exam technique can accurately diagnose both the plical bands as well as the sensitive synovial tissue. LEVEL OF EVIDENCE: Level II, Diagnostic Study.
