Modified laparoscopic gastrostomy tube placement in children: Does subcutaneous suture type matter?

BackgroundLaparoscopic gastrostomy tube (GT) placement carries the risk of early tube dislodgement and is often modified with absorbable subcutaneously-tunneled transabdominal tacking sutures that can aid in tube replacement. However, these buried sutures may increase the risk of surgical site infection (SSI). This study sought to evaluate SSI rates associated with different types of transabdominal tacking sutures used in modified laparoscopic GT placement.MethodsA single-institution, retrospective review was performed of all patients ≤18 years-old undergoing modified laparoscopic GT placement between September 2016 and March 2020. Patients were stratified into three groups by suture type used, and the primary outcome was SSI within six weeks of surgery. Demographic and perioperative data were analyzed by chi-square or Fisher's exact test.ResultsA total of 113 modified laparoscopic GT placements were performed at a median age of 9 months (interquartile range 3 months to 3 years). Prophylactic antibiotic use was similar between groups. Eleven patients (10%) developed an SSI, and all were treated with antibiotics alone. No SSIs were observed with the use of poliglecaprone suture (n = 46), and higher SSI rates were observed with use of polyglactin (n = 17) and polydioxanone (n = 51) suture (18% polyglactin vs. 16% polydioxanone vs. 0% poliglecaprone, p<0.05). No differences were observed in rates of early postoperative dislodgement, leakage, or granulation tissue.ConclusionAbsorbable braided and long-lasting monofilament transabdominal tacking sutures may increase risk of SSI following modified laparoscopic gastrostomy tube placement. In this cohort, the use of poliglecaprone (Monocryl) suture was associated with no SSIs and similar rates of postoperative dislodgement, leakage, and granulation tissue.Level of Evidence: Treatment Study, Level III     

Resource utilization after gastrostomy tube placement: Defining areas of improvement for future quality improvement projects

BackgroundGastrostomy tube (GT) placement is a frequent procedure at a tertiary care children's hospital. Because of underlying patient illness and the nature of the device, patients often require multiple visits to the emergency room for GT-related concerns. We hypothesized that the majority of our patient visits to the ER related to gastrostomy tube concerns were not medically urgent. The purpose of this study was to characterize the incidence and indications for GT-related emergency room visits and readmission rates in order to develop family educational material that might allow for these nonurgent concerns to be addressed on an outpatient basis.MethodsWe reviewed the medical records of all patients with GT placement in the operating room from January 2011 to September 2012. We evaluated our primary outcome of ER visits at less than 30 days after discharge and 30–365 days after discharge. The purpose of the ER visit was categorized as either mechanical (dislodgement, leaking) or wound-related (infection, granulation tissue). Additional outcomes assessed included readmission rates, reoperation rates, and the use of gastrostomy contrast studies.ResultsDuring the study period, 247 patients had gastrostomy tubes placed at our institution at a median age of 15.3 months (range 0.03 months–22 years). Of the total patient population, 219 were discharged less than 30 days after their operation (89%). Of these, 42 (20%) returned to the emergency room a total of 44 times within 30 days of discharge for concerns related to their GT. Avoidable visits related to leaking, mild clogs, and granulation tissue were seen in 17/44 (39%). An additional 40 patients among the entire cohort of 247 (16%) presented to the ER a total of 71 times 31–365 days post-discharge; 59 (83%) of these visits were potentially avoidable. The readmission rate related to the GT was low (4%).ConclusionsFew studies have attempted to quantify the amount of postoperative resources utilized post-GT placement in children. Our findings indicated this is not an insignificant quantity. In response to these findings, we have developed a series of educational materials and identified a dedicated nurse to perform inpatient gastrostomy education to these patients prior to discharge.     

The effect of standardized discharge instructions after gastrostomy tube placement on postoperative hospital utilization

Background/PurposeGastrostomy tube (GT) placement is a common pediatric procedure with high postoperative resource utilization. We aimed to determine if standardized discharge instructions (SDI) reduced healthcare utilization rates.MethodsWe performed a retrospective cohort study comparing postoperative hospital utilization of patients who underwent initial GT placement pre- and post-SDI protocol implementation from 2014–2019. Statistical analyses included Chi-square tests, multivariable adjusted logistic regression, adjusted Cox proportion hazard regression, and adjusted Poisson regression models when appropriate.Results197 patients were included, 102 (51.8%) before and 95 (48.2%) after protocol implementation. On primary analysis, SDI patients did not have significantly different total postoperative hospital utilization events at 30-days (48.0% vs. 38.9%, p = 0.25). On secondary analysis, SDI patients had lower rates of ED (8.4% vs. 19.6%, p = 0.026) and office visits (11.6% vs. 25.5%, p = 0.017) at 30-days. Non-SDIs patients had greater odds of ED visits (OR2.7, 95%CI 1.3–5.9, p = 0.01), office visits (OR3.7, 95%CI 1.7-8.1, p = 0.001) and phone calls (OR2.6, 95%CI 1.2–5.7, p = 0.016) at 1-year. The adjusted hazard ratio was 2.0 (95%CI 1.4–3.0, p < 0.001). Incident rate ratio were 1.8 (95%CI 1.2–2.5, p = 0.002) at 30-days and 1.9 (95%CI 1.5–2.4, p < 0.001) at 1-year post-discharge.ConclusionsSDIs post-GT placement may reduce multiple aspects of postoperative hospital utilization.     

Operative techniques and long-term outcomes of hypospadias repair in the absence of preputial skin after neonatal circumcision

PurposeTo present the results of hypospadias repair in the absence of preputial skin following neonatal circumcision, and the analyses of surgical techniques and predictors of procedural success.MethodsRecords of all children who underwent hypospadias repair between 10/1999 and 12/2018 were retrospectively reviewed. All of those who underwent neonatal circumcision prior to surgery were included. Patients with any prior penile reconstruction surgery and those with the megameatus intact prepuce variant were excluded. The primary endpoint was the need for reoperation.ResultsA total of 69 patients with a history of neonatal circumcision underwent surgical reconstruction of hypospadias during the study period. Their mean age at surgery was 14 months (interquartile range [IQR] 9,22). Forty-five cases (65%) involved distal hypospadias, and ventral curvature was present in 24 (35%). Dartos flaps were harvested from the dorsal aspect in 37/58 (64%) patients and from the ventral aspect in 21/58 (36%). Twenty-two patients (22/69, 32%) required reoperation after a median follow-up of 9 years (IQR 6,13). Indications for revision surgery included urethral fistula (n = 16, 22%), meatal stenosis (n = 5, 7%), and skin redundancy (n = 1). Ventral curvature (odds ratio [OR] 3.5, p = 0.02) and higher grades of hypospadias. (OR 3.3, p = 0.03) had a higher probability of reoperation (univariate logistic regression).ConclusionHypospadias repair following neonatal circumcision in the absence of preputial skin is a challenging reconstruction. The reoperation rate in our cohort was 30%, similar to reoperative hypospadias surgery. Parents of newborns diagnosed with hypospadias should be encouraged to refrain from pre surgical neonatal circumcision.Level of evidenceTreatment study, level IV     

Predictors of postoperative emergency department visits after laparoscopic bariatric surgery

BackgroundPostoperative emergency department (ED) visits are a quality metric for bariatric surgical programs. Predictive factors of ED visits that do not result in readmission are not clear.ObjectivesWe aimed to identify predictors of ED visits in patients without readmission after laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB).SettingThe Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database.MethodsThe MBSAQIP database was queried for patients who underwent LSG and LRYGB from 2015 through 2017. Patients were grouped by those who presented to the ED (ED group) and those who did not. ED visits analyzed included only those that did not result in readmission. Multivariable forward selection logistic regression was used to report adjusted odds ratios (AORs) with 95% CIs for ED visits.ResultsOf 276,073 patients, 257,985 (93.4%) were in the group who did not present to the ED, and 18,088 (6.6%) were in the ED group. Most underwent LSG (71.9%) versus LRYGB (28.1%). Multivariable forward logistic regression identified outpatient treatment for dehydration (AOR, 22.26; 95% CI, 21.30–23.27; P < .001) as the most predictive factor of an ED visit, followed by urinary tract infection (AOR, 7.25; 95% CI, 6.22–8.46; P < .001), wound disruption (AOR, 4.63; 95% CI, 3.09–6.96; P < .001), and surgical site infection (AOR, 3.80; 95% CI, 3.38–4.28; P < .001).ConclusionsPostoperative complications were the strongest predictors of ED visits after laparoscopic bariatric surgery. Quality improvement initiatives should target these variables to decrease postoperative ED visits.     

Preoperative Risk Factor Optimization Lowers Hospital Length of Stay and Postoperative Emergency Department Visits in Primary Total Hip and Knee Arthroplasty Patients

BackgroundThe evaluation and management of outcomes risk has become an essential element of a modern total joint replacement program. Our multidisciplinary team designed an evidence-based tool to address modifiable risk factors for adverse outcomes after primary hip and knee arthroplasty surgery.MethodsOur protocols were designed to identify, intervene, and mitigate risk through evidence-based patient optimization. Nurse navigators screened patients preoperatively, identified and treated risk factors, and followed patients for 90 days postoperatively. We compared patients participating in our optimization program (N = 104) to both a historical cohort (N = 193) and a contemporary cohort (N = 166).ResultsRisk factor identification and optimization resulted in lower hospital length of stay (LOS) and postoperative emergency department (ED) visits. Patients in the optimization cohort had a statistically significant decrease in mean LOS as compared to both the historical cohort (2.55 vs 1.81 days, P < .001) and contemporary cohort (2.56 vs 1.81 days, P < .001). Patients in the optimization cohort had a statistically significant decrease in 30- and 90-day ED visits compared to the historical cohort (P_30-day = .042, P_90-day = .003). When compared with the contemporary cohort, the optimization cohort had a statistically significant decrease in 90-day ED visits (21.08% vs 10.58%, P = .025). The optimization cohort had a statistically significant increase in the percentage of patients discharged home. We noted nonsignificant reductions in readmission rate, transfusion rate, and surgical site infections.ConclusionOptimization of patients before elective primary total hip arthroplasty and total knee arthroplasty reduced average LOS, ED visits, and drove telerehabilitation use. Our results add to the limited body of literature supporting this patient-centered approach.     

Patterns of readmission and reoperation within 90 days after Roux-en-Y gastric bypass

BackgroundHealth insurance payors harbor concerns regarding the cost of bariatric procedures that are chiefly related to early readmissions and reoperations. We have attempted to identify the avoidable causes of readmission.MethodsWe retrospectively reviewed the indications for short-term (<90-d) emergency department (ED) visits, readmissions, and reoperations from August 2004 through May 2007 for patients undergoing primary Roux-en-Y gastric bypass (RYGB) for morbid obesity at a tertiary care teaching hospital. The electronic medical record of the primary hospital was reviewed, as well as the electronic medical records of 9 local hospitals serving the area, allowing the incorporation of data from 35 locoregional hospitals.ResultsA total of 1222 consecutive patients underwent RYGB, 1051 laparoscopically. Of these 1222 patients, 173 had 252 ED visits, readmissions, and/or reoperations; 147 (58%) visits were to the primary institution and 105 (42%) occurred at a local or regional hospital. No age difference was found between the patients who underwent ED visits, hospital readmissions, or reoperations and those who did not (mean age 43 yr for both groups, P > .05). Patients who were seen in the ED, readmitted to the hospital, or underwent reoperation had had a greater body mass index (50 kg/m² versus 48 kg/m², P = .001). On average, the readmissions occurred 27.3 days (range 2–88) postoperatively, and the mean hospital length of stay for readmitted patients was 3.3 days (range 1–16). Patients who presented for ED visits, readmission, or reoperations were more likely to have undergone open RYGB than laparoscopic RYGB (P = .002). The <90-day all-cause ED visit, readmission, and reoperation rate was 21% (n = 252). Considering all 1222 patients, the incidence of nausea, vomiting, and dehydration, abdominal pain, and wound issues was 5% (n = 65), 4% (n = 50), and 2% (n = 21), respectively. Considering only the 173 patients with ED visits, readmissions, or reoperations (n = 252), the admitting diagnosis was nausea, vomiting, and dehydration in 26%, abdominal pain in 20%, and wound issues in 8%. The unemployed, disabled, or retired were more likely to have been seen in the ED or readmitted compared with the employed, nondisabled, or not retired (P = .01).ConclusionA considerable number of patients are affected by nausea, vomiting, and dehydration, abdominal pain, and wound issues <90 days postoperatively. Socioeconomic and functional status might have an effect on the rate of ED visits and readmissions. By ensuring that the appropriate outpatient mechanisms for management of these problems are available, early ED visits and readmission rates should significantly decrease.     

Emergency department utilization following pediatric gastrostomy tube placement is driven by a small cohort of patients

PurposePediatric gastrostomy tubes (G-tubes) are associated with frequent postoperative problems and consumption of healthcare resources. We hypothesized that a small cohort of patients disproportionately drives healthcare resource utilization after G-tube insertion. This study aimed to characterize this population in order to implement evidence-based pathways to reduce healthcare utilization after G-tube insertion.MethodsAll surgically placed pediatric G-tubes at a quaternary care center between March 2011 and June 2018 were retrospectively reviewed. Healthcare utilization including radiographic studies, emergency department (ED) visits, hospital admissions, procedures, and diagnoses was abstracted. Encounter specific charges based on CPT codes were collected. Statistical analyses were performed with Mann Whitney U, Fisher's Exact Test, and multivariate nominal logistic regression. Institutional review board approval was obtained.ResultsDuring the study period, 189 patients underwent G-tube insertion; 24% of patients presented to the ED two or more times and accounted for 82% of ED visits. This cohort of high ED utilizers was more likely to present with G-tube dislodgement [both within the first three months (early) and after three months (late)], required more radiographic studies, and accrued significantly more charges compared to low ED utilizers. Multivariate analyses demonstrated high ED utilization was significantly associated with non-Caucasian race and the surgeon performing the procedure.ConclusionsAt our institution, a significant proportion of healthcare utilization following G-tube placement is consumed by a relatively small cohort of children. Future efforts will target patients with two or more G-tube related ED visits or an early G-tube dislodgement for additional education and integration with outpatient resources.Type of studyRetrospective study.Level of evidenceLevel II.     

Outcomes of gastrostomy placement with and without concomitant tracheostomy among ventilator dependent children

IntroductionSimultaneous gastrostomy tube (GT) and tracheostomy placement in young children offers potential benefit in limiting anesthetic exposure, but it is unknown whether combining these procedures introduces additional morbidity. This study compared outcomes after combined GT and tracheostomy placement versus GT placement alone among similar ventilator-dependent patients.MethodsVentilator-dependent children <2-years-old who underwent GT placement alone (MV-GT), simultaneous GT and tracheostomy placement (GT+T), and GT placement alone with a pre-existing tracheostomy (T-GT) were identified using 2012–2018 NSQIP-Pediatric Participant User Files. Multiple logistic regression models were used to compare outcomes while adjusting for other group differences.ResultsAmong 1100 children, 351 underwent MV-GT, 494 GT+T, and 255 T-GT. Major complications occurred in 23.6%, 17.0%, and 14.5% of the respective groups (p = 0.01). Major complications with GT+T were similar to T-GT (adjusted odds ratio [aOR]=1.19, 95%CI:0.78–1.83, p = 0.4) and lower than MV-GT (aOR=0.67, 95%CI:0.47–0.95, p = 0.02). Severe complications including mortality, cardiac arrest, and stroke were similar between the three groups (p = 0.8).ConclusionsChildren <2-years-old undergoing GT+T did not experience higher post-operative complications compared to children undergoing T-GT or MV-GT. Utilizing GT+T to limit anesthetic exposure may be reasonable within this high-risk population.Type of StudyTreatment StudyLevel of EvidenceLevel III     

Reasons and Risk Factors for Emergency Department Visits After Primary Total Knee Arthroplasty: An Analysis of 1.3 Million Patients

BackgroundWell-powered studies investigating the relationship of emergency department (ED) visits and total knee arthroplasty (TKA) are limited. Therefore, the specific aims of this study were to: 1) compare patient demographics of patients who did and did not have an ED visit; and for the visits, identified: 2) leading reasons; and 3) risk factors for ED visits (prearthroplasty/postarthroplasty).MethodsPatients undergoing primary TKA who had an ED visit within 90 days after their index procedure were identified from a nationwide database. The query yielded 1,364,655 patients who did (n = 5689) and did not have (n = 1,358,966) an ED visit. Baseline demographics such as age, sex, and comorbidity prevalence between the two cohorts; reasons for ED visits; and prearthroplasty and postarthroplasty risk factors were analyzed. Odds ratios (ORs) of ED visits were assessed using multivariate binomial logistic regression analyses. A P-value less than 0.001 was considered statistically significant.ResultsPatients who did and did not have ED visits differed with respect to age (P < .0001) and mean Elixhauser Comorbidity Index scores (9 vs 6, P < .0001). Musculoskeletal etiologies were the most common reason for ED visits. Hypertension was the greatest contributor to ED visits prearthroplasty and postarthroplasty. Comorbid conditions associated with ED visits postarthroplasty included peripheral vascular disease (OR: 1.61, P < .0001), coagulopathy (OR: 1.58, P < .0001), and rheumatoid arthritis (OR: 1.56, P < .0001).ConclusionBy identifying demographic patterns of patients, reasons, and risk factors, the information found from this study can help identify targets for quality improvement to potentially reduce the incidence of ED visits after primary TKA.     

The effect of inpatient versus outpatient location on postoperative healthcare utilization after neonatal circumcision

Background/PurposeNeonatal circumcision is a common pediatric procedure performed in both the inpatient and outpatient setting. We aimed to determine if procedure location affected 30-day post-procedure healthcare utilization rates, inpatient length of stay (LOS), and amount charged.MethodsWe performed a retrospective cohort study comparing 30-day postoperative healthcare utilization (emergency department (ED) visits, office visits, readmissions) of full-term infants who underwent an outpatient versus inpatient (same admission as birth) circumcision from 2015 to 2020. Statistical analyses included Chi-square tests, multivariable adjusted logistic regression models when appropriate.Results3137 infants were included, 1426 (45.5%) had an outpatient circumcision, 1711 (54.5%) an inpatient. Outpatient had similar overall healthcare utilization rates as inpatients (5.7% vs. 5.6%, p = 0.933). The number of ED visits (1.5% vs 0.8%, p = 0.055), office visits (4.5% vs. 5.1%, p = 0.437), and readmissions (0.2% vs. 0.0%, p = 0.058) were not significantly different. Infants with inpatient circumcisions had longer LOS after adjusting for age, ethnicity and delivery type (Cesarean versus vaginal) with an incident rate ratio of 1.97 (95% confidence interval 1.84–2.11, p<0.001). Outpatient circumcision resulted in average charges of $372 more than inpatient.ConclusionsOutpatient circumcision has a minimal effect on healthcare utilization rates but lead to a shorter hospital stay following birth and increased charge.Study DesignRetrospectiveLevel of EvidenceIII     

Outpatient Total Hip Arthroplasty Performed at an Ambulatory Surgery Center vs Hospital Outpatient Setting: Complications,Revisions, and Readmissions

BackgroundOutpatient total hip arthroplasty (THA) utilization continues to grow. Literature suggests outpatient THA may result in low rates of complications and readmission. There are no studies comparing safety profiles of THA performed at ambulatory surgery centers (ASC) vs hospital outpatient (HOP) settings.MethodsProspectively collected data were reviewed on all patients who underwent THA from 2013 to 2018. ASC and HOP subgroups were compared, investigating difference in demographics, comorbidities, American Society of Anesthesiologists subgroups, all complications, revisions, emergency department (ED) visits, and readmissions within the first 90 days of surgery. An additional subgroup analysis of patients younger than 65 years was performed.ResultsTwo surgeons performed 3063 THAs during the study period, including 965 outpatient cases (ASC = 335; HOP = 630). Thirty-seven (3.8%) complications occurred within 90 days. No differences were found between groups for 90-day complication rates (ASC = 13, 3.9%; HOP = 24, 3.8%; P = .48), revision rates (ASC = 0, 0%; HOP = 2, .3%; P = .30), all-cause reoperation rates (ASC = 1, 0.3%; HOP = 5, 0.8%; P = .35), ED visits (ASC = 3, 0.9%; HOP = 2, 0.3%; P = .23), or readmission rates (ASC = 2, 0.6%; HOP = 9, 1.4%; P = .25).ConclusionTHA can be safely performed in both ASC and HOP settings with low 90-day postoperative complication, revision, reoperation, ED visit, and readmission rates. Based on the populations studied, we identified no statistically significant differences in rates of complications between ASC and HOP groups.     

Evaluation of Emergency Department Visits Following Total Joint Arthroplasty: Same-Day Discharge vs Non–Same-Day Discharge

BackgroundTraditionally, most efforts have focused on readmission rates while little has been reported on emergency department (ED) presentation. This study aims to analyze the difference between same-day discharge (SDD) and non-SDD primary total hip and knee arthroplasty cases to determine the rate and reasons associated with 90-day ED presentations.MethodsWe retrospectively reviewed all patients who underwent primary total hip arthroplasty and total knee arthroplasty between 2011 and 2021. The patients were separated into 2 cohorts: (1) SDD and (2) required a longer length of stay. The primary outcome was an ED visit within 90 days of the index operation. Secondary outcomes included reasons for ED visits and readmission rates. Multivariable logistic regressions were performed to compare the 2 groups while accounting for significant demographic variables.ResultsOf the 24,933 patients included, 1,725 (7%) were SDD and 23,208 (93%) required a longer length of stay. The overall rate of 90-day ED visits was significantly lower for patients who were SDD compared to non-SDD (1.6% vs 4.0%, P = .004). However, when stratified based on the reason for ED visit, no single cause was significant between the 2 cohorts. The most commonly reported reasons were pain (32.1% vs 26.7%, P = .064) and other non–orthopedic-related medical issues (25.0% vs 29.5%, P = .206). Among those who presented to the ED, the readmission rate did not statistically differ (25.0% vs 23.4%, P = .131).ConclusionPatients who underwent SDD were less likely to present to the ED within 90 days following their surgery compared to non-SDD. Approximately three fourths of the patients in both cohorts that visited the ED did not require readmission. Future efforts should focus on developing interventions to reduce the burden of these visits on the healthcare system.Level III EvidenceRetrospective Cohort Study.     

What Goes Bump in the Night: An Evaluation of Emergency Department Visits Following Total Joint Arthroplasty

BackgroundInterest in postoperative healthcare utilization has increased following the implementation of episode-of-care funding for elective orthopedic surgery. Most efforts have focused on readmission; however, little has been reported on emergency department (ED) presentation. We analyzed elective, primary total hip or knee arthroplasty (THA and TKA) cases to determine the rate, reasons, risk factors, timing, and hospital cost associated with 30-day ED presentations.MethodsAn observational study of patients who underwent primary, elective TKA and THA between January 1, 2016, and December 31, 2017, was performed. The primary outcome was an ED visit within 30-days of the index operation. Secondary outcomes included reasons, risk factors, timing, and hospital cost of ED visits. A multivariable logistic regression was undertaken to determine patient factors associated with ED presentation.ResultsOverall, 1690 patients were included, of which 9.2% presented to the ED within 30-days of surgery. Approximately two-thirds of the visits were after-hours, and most were discharged home without readmission (81.4%). The most commonly reported reasons were wound concerns (30.1%) and pain (20.5%). Older age (OR 1.1, P = .03) and preoperative dyspnea (OR 2.1, P < .001) increased the odds of ED visits. The mean cost of an ED visit was significantly greater after-hours (P = .015).ConclusionOverall, 1 in 10 patients undergoing TKA/THA presented to the ED within 30-days of surgery, of which over 80% were not readmitted, and most occurred after-hours where cost is greatest. Our observations suggest ED visits following TKA/THA are common, and most are likely preventable. Future efforts should focus on developing interventions to reduce these visits.     

The Role of Malnutrition in Ninety-Day Outcomes After Total Joint Arthroplasty

BackgroundResearch has linked malnutrition to more complications in total joint arthroplasty (TJA) patients. The role of preoperative albumin in predicting length of stay (LOS) and 90-day outcomes remains understudied. Often, an albumin cut-off ≤3.5 g/dL is used as proxy for malnutrition, although this value remains understudied. This preoperative level may be missing some patients at risk for adverse events post TJA.MethodsTJA patients at a single institution from 2013 to 2018 were reviewed for preoperative albumin level. In total, 4047 cases (total knee arthroplasty: 2058; total hip arthroplasty: 1989) had available data, including 90-day readmissions, 90-day emergency department (ED) visits, and postoperative LOS.ResultsAbout 5.6% experienced a readmission and 9.6% had at least one ED visit within 90 days. Overall prevalence of malnutrition was 3.6%, and this cohort experienced a longer average LOS (3.5 vs 2.2 days, P < .0001) and was more likely to experience a readmission (16% vs 5%, P < .0001) or ED visit (18% vs 9%, P = .0005). Additionally, albumin ≤3.5 g/dL was correlated with more frequent discharge to skilled nursing facility/rehab (30.8% vs 14.7%, P < .0001), increased risk for 90-day readmission with univariable (odds ratio [OR] 1.79, P < .0001) and multivariable logistic regression (OR 1.55, P < .0001), and increased risk for 90-day ED visits with univariable (OR 1.62, P < .0001) and multivariable regression (OR 1.35, P < .0001). The optimal albumin cut-off was 3.94 g/dL in a univariable model for 90-day readmission.ConclusionScreening for malnutrition may serve a role in preoperative evaluation. An albumin cutoff value of 3.5 g/dL may miss some at-risk patients.     

No Difference in the Rate of Periprosthetic Joint Infection in Patients Undergoing the Posterolateral Compared to the Direct Anterior Approach

BackgroundThere remains inconsistent data about the association of surgical approach and periprosthetic joint infection (PJI). We sought to evaluate the risk of reoperation for superficial infection and PJI after primary total hip arthroplasty (THA) in a multivariate model.MethodsWe reviewed 16,500 primary THAs, collecting data on surgical approach and all reoperations within 1 year for superficial infection (n = 36) or PJI (n = 70). Considering superficial infection and PJI separately, we used Kaplan–Meier survivorship to assess survival free from reoperation and a Cox Proportional Hazards multivariate models to assess risk factors for reoperation.ResultsBetween direct anterior approach (DAA) (N = 3,351) and PLA (N = 13,149) cohorts, rates of superficial infection (0.4 versus 0.2%) and PJI (0.3 versus 0.5%) were low and survivorship free from reoperation for superficial infection (99.6 versus 99.8%) and PJI (99.4 versus 99.7%) were excellent at both 1 and 2 years. The risk of developing superficial infection increased with high body mass index (BMI) (hazard ratio [HR] = 1.1 per unit increase, P = .003), DAA (HR = 2.7, P = .01), and smoking status (HR = 2.9, P = .03). The risk of developing PJI increased with the high BMI (HR = 1.04, P = .03), but not surgical approach (HR = 0.68, P = .3).ConclusionIn this study of 16,500 primary THAs, DAA was independently associated with an elevated risk of superficial infection reoperation compared to the PLA, but there was no association between surgical approach and PJI. An elevated patient BMI was the strongest risk factor for superficial infection and PJI in our cohort.Level of EvidenceIII, retrospective cohort study.     

Assessment of safety and effectiveness of non-neurosurgical management for minimal traumatic brain injury (TBI)

BackgroundPatients with mild traumatic brain injury (TBI) and intracranial hemorrhage often receive neurosurgical consultation. However, only a small proportion of patients require intervention. Our hypothesis is that low-risk minimal TBI patients managed without immediate neurosurgical consultation will have a reasonable safety and effectiveness outcome profile.MethodsA non-neurosurgical management protocol for adult minimal TBI was implemented at a level I trauma center as an interdisciplinary quality-improvement initiative in November 2018. Minimal TBI was defined as Glasgow Coma Scale (GCS) of 15 secondary to blunt mechanism, without anticoagulant or antiplatelet therapy, and isolated pneumocephalus and/or traumatic subarachnoid hemorrhage on head CT imaging. Safety was assessed by in-hospital mortality, neurosurgical interventions, and ED revisits within two weeks of discharge. Effectiveness was assessed by neurosurgical consult rate and length of stay. Outcomes were compared 8-months pre- and post-protocol implementation.ResultsA total of 97 patients were included, of which 49 were pre-protocol and 48 were post-protocol There was no difference in rates of in-hospital mortality [0 (0%) vs 0 (0%)], neurosurgical procedure [1 (2.1%) vs 0 (0%)], operations [0 (0%) vs 0 (0%)], and ED revisits [1 (2.0%) vs 2 (4.2%), p = 0.985] between the periods. There was a significant reduction in neurosurgical consults post-protocol implementation (92% vs 29%, p<0.001).ConclusionA protocol for minimal TBI patients effectively reduced neurosurgical consultation without changes in safety profile. Such an interdisciplinary management protocol for low-risk neurotrauma can effectively utilize the neurosurgery consult services by stratifying neurologically stable TBI patient.     

Unicompartmental Knee Arthroplasty: More Conversions,Fewer Complications Than Proximal Tibial Osteotomy in a Young Population

BackgroundPatients with isolated medial compartment osteoarthritis requiring surgical intervention generally have two surgical options: unicompartmental knee arthroplasty (UKA) and proximal tibial osteotomy (PTO). Outcomes of reoperation rates and survivorship are important for counseling patients on treatment options.MethodsA retrospective, comparative cohort study was performed for a consecutive series of patients in the Military Health System who underwent either UKA or PTO between 2003 and 2018. All patients were between 18 and 55 years old and diagnosed with isolated medial compartmental arthritis. Cases with concurrent meniscal or cartilage procedures were included, while cases with concurrent ligament reconstruction were excluded. A minimum 2-year follow-up was required. The primary outcome was conversion to total knee arthroplasty, and the secondary outcome was reoperation for any reason.ResultsA total of 383 procedures were performed for isolated medial compartment arthritis in 303 patients (UKA 270, PTO 113). A multivariate analysis showed that PTO was associated with decreased risk of conversion to TKA compared to UKA (P = .0364). However, the reoperation due to complications was significantly higher in the PTO group (21.2% vs 2.2%; P ≤ .01). The 5-year conversion rate was 13.7% for UKA and 3.5% for PTO (P = .0033) with an average time to conversion of 3.1 years for UKA and 2.9 years for PTO (P = .7805).ConclusionsIn young patients with isolated medial compartment arthritis, conversion rates to TKA are higher with UKA compared to PTO. However, overall reoperation rate is higher with PTO, secondary to complications and revision procedures. Overall survivorship is acceptable for both procedures.     

The impact of intraoperative residual mild regurgitation after repair of degenerative mitral regurgitation

ObjectivesDuring degenerative mitral repair, surgeons must decide if further repair is warranted for residual mild mitral regurgitation. We examined the incidence of mild mitral regurgitation, late echocardiographic and clinical outcomes, and influence of surgical experience in decision making.MethodsFrom April 2004 to June 2018, 1155 of 1195 patients with pure degenerative disease underwent repair (97% repair rate). Propensity score matching was performed between patients with trace/no mitral regurgitation and patients with mild residual mitral regurgitation. Late echocardiographic outcome and freedom from reoperation were compared using competing-risks models. A comparison of outcomes of the referent surgeon (89.8% of repairs) with all other surgeons was performed.ResultsMild mitral regurgitation was present in 73 patients (6%). Propensity score–matched analyses compared 69 patients with mild mitral regurgitation with 198 patients without mitral regurgitation. Late moderate or greater mitral regurgitation was higher in those with mild mitral regurgitation than in those with no mitral regurgitation (17% vs 7%, P = .033), as was late moderate-severe or greater mitral regurgitation (6% vs 1%, P = .016). Ten-year freedom from reoperation was low in both groups (99.5% no vs 96.9% mild; P = .10). The referent surgeon had fewer patients with mild residual mitral regurgitation (6% vs 11%, P = .027) and less progression of mitral regurgitation compared with other surgeons (late moderate or greater mitral regurgitation 6% vs 15%, P = .002).ConclusionsResidual mild mitral regurgitation was uncommon, and late progression to moderate or greater mitral regurgitation was rare and never led to late mitral reoperation. Experienced surgeons may be better able to determine repairs likely to remain stable, and most mild residual mitral regurgitation does not require re-repair.
