Satisfaction With the Process vs Outcome of Care in Total Hip and Knee Arthroplasty.

BACKGROUND: Patient satisfaction, with both process of care and outcome of care, is critical for measuring the quality and value of elective procedures such as arthroplasty. The purpose of this study is to evaluate the correlation between early postoperative satisfaction with the process of care and 2-year satisfaction with the outcome of care after total hip arthroplasty (THA) and total knee arthroplasty (TKA). METHODS: We retrospectively analyzed data from institutional arthroplasty registries. Satisfaction with the outcome of care was measured on a scale of 0-100 by a previously validated questionnaire administered 2 years postoperatively. Patient satisfaction with the process of care was measured by the Press Ganey (PG) inpatient survey, also scored 0-100. We examined the correlation between these 2 measures of satisfaction in patients who underwent primary THA or TKA. RESULTS: In total, 721 TKA patients and 760 THA patients underwent surgery and completed both the PG survey and 2-year satisfaction questionnaire. The mean age was 65.1 years with a mean body mass index of 28.8 and 56% were female. The mean PG survey score for the entire cohort was 95.6. The mean 2-year satisfaction score was 90.3. The Spearman correlation coefficient between the PG survey and the 2-year satisfaction survey was 0.23 for TKA patients (P < .001) and 0.13 for THA patients (P < .001). CONCLUSION: We found a weak correlation between the measurement of satisfaction with the process of care surrounding hip and knee arthroplasty using the PG survey and measurement of satisfaction with the outcome of care after arthroplasty using a validated 2-year satisfaction instrument.

Clinical characteristics and patient-reported outcomes of total shoulder arthroplasty after anterior stabilization: a retrospective matched control study.

BACKGROUND: Instability arthropathy is a known cause of glenohumeral osteoarthritis (OA) among patients with and without prior shoulder stabilization. This study aims to compare the clinical, radiographic, and patient-reported outcome measure (PROM) scores among total shoulder arthroplasty (TSA) patients with and without a history of shoulder stabilization. METHODS: A case-control study was performed comparing 20 patients with a history of anterior shoulder stabilization (11 open, 9 arthroscopic) who underwent TSA to a matched cohort of 20 TSA patients without a history of shoulder surgery (mean follow-up = 2.8 years). Patients were matched by sex, age, and baseline American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) score within 10 points (mean age 59.6 ± 9.6 years). Patient characteristics, operative findings, and preoperative and postoperative radiographic characteristics for both groups were reported. Comparisons were made regarding PROM scores (ASES, 12-Item Short Form Health Survey (SF-12), Shoulder Activity Scale [SAS], numeric rating scale for pain) at baseline, 2 years, and 5 years and patient satisfaction at 2 years. RESULTS: Intraoperative findings of subscapularis scarring or attenuation was common among patients with prior anterior stabilization. The instability cohort did have a higher percentage of B2/B3 glenoid types than the OA cohort (45% vs. 15%), but this was not significantly different possibly because of the small sample size. At 2 years, both instability and OA groups reported significant improvement in pain, function, and activity level. There was no difference between groups on any PROMs or patient satisfaction level. At 5 years, instability patients had significantly lower scores on the ASES and the SF-12 PCS than the OA group. CONCLUSION: There was notable alterations in both soft tissue and bony morphology among patients with prior anterior stabilization. After TSA, both instability and primary OA groups showed significant improvements at 2 years. However, PROMs for instability patients deteriorated at 5 years compared with the control group. Complex bony and soft tissue imbalances may contribute to more unpredictable long-term PROM scores. Thoughtful preoperative consideration of these factors should influence decision making regarding selection of TSA for management of OA in this complex patient cohort.

Medical alert tattoos-A pinch of style along with patient safety.

The use of medical tattoos can potentially be life-saving. We present a 16-year-old patient who chose to tattoo a medical condition on her forearm. Her tattoo is more extensive than most medical tattoos and shows the measures a mother will take to ensure her daughter's safety. To our knowledge, there are no published guidelines recommending an ideal location or symbology for a medical tattoo. Such guidelines would be useful to artists, as well as to medical personnel in emergencies if the patient has a tattoo.

Disease burden and pain in obese cancer patients with chemotherapy-induced peripheral neuropathy.

PURPOSE: Chemotherapy-induced peripheral neuropathy (CIPN) and obesity are prevalent in cancer survivors and decrease quality of life; however, the impact of the co-occurrence of these conditions has garnered little attention. This study investigated differences between obese and non-obese cancer survivors with CIPN and predictors of symptom burden and pain. METHODS: Patients with CIPN were administered the MD Anderson Symptom Inventory and a modified version of pain descriptors from the McGill Pain Inventory. Independent t tests assessed group differences between obese and non-obese survivors, and linear regression analyses explored predictors of patient outcomes. RESULTS: Results indicated a significant difference in symptom severity scores for obese (M = 32.89, SD = 25.53) versus non-obese (M = 19.35, SD = 16.08) patients (t(37.86) = -2.49, p = .02). Significant differences were also found for a total number of pain descriptors endorsed by obese (M = 4.21, SD = 3.45) versus non-obese (M = 2.42, SD = 2.69) participants (t(74) = -2.53, p = .01). Obesity was a significant predictor of symptom severity and total pain descriptors endorsed. Other significant predictors included age and months since treatment. CONCLUSIONS: Cancer survivors with CIPN and co-occurring obesity may be more at risk for decreased quality of life through increased symptom severity and pain compared to non-obese survivors. This paper identified risk factors, including obesity, age, and months since treatment, that can be clinically identified for monitoring distress in CIPN patients. Future research should focus on the longitudinal relationship between obesity and CIPN, and robust interventions to address the multifaceted issues faced by cancer survivors.

Water extract from Pleurotus pulmonarius with antioxidant activity exerts in vivo chemoprophylaxis and chemosensitization for liver cancer.

Chemoprophylaxis and chemosensitization are promising strategies to combat human cancers. Natural antioxidant agents show great promise in cancer therapy, and the use of edible mushrooms against cancer is receiving more interest globally. In this study, the radical scavenging activities including diphenyl-1-picrylhydrazyl, superoxide anion radical, hydroxyl radical, and hydrogen peroxide were compared among hot water extracts from 3 edible mushrooms, among which Pleurotus pulmonarius (Pp) possessed the highest antioxidant potential. Oral administration of Pp 2 wk in advance could markedly inhibit the incidence and size of tumor (Huh7 liver cancer cells) with an inhibition rate of 93.1% in nude mice. No obvious side effect was observed in the Pp-treated mice as indicated by their body weight and histological analysis of major organs. The cancer prevention by Pp treatment might be explained by the inhibition of cancer cell proliferation indicated by reduction of ki-67 staining and the inactivation of phosphoinositide 3-kinase (PI3K)/AKT signaling pathway in the Pp-treated mice. Furthermore, a significant synergistic effect was observed when the mice were treated with a combination of low dose of cisplatin and Pp. Taken together, these results suggest the potential application of Pp as an adjuvant in the chemotherapy of liver cancer.

Comparing the emotional experiences of students in similar dissection- and prosection-based medical gross anatomy courses: A mixed-methods study.

The anatomy laboratory can incite strong emotional reactions in students, which can in turn facilitate growth in empathy, care for vulnerable others, and professionalism. Despite this, little is known about the relative emotional impacts of different laboratory modalities. The response to the COVID-19 pandemic created an opportunity to compare the emotional experiences of students in similar courses in which one group of students dissected donors and the other group learned from prosected donors. The courses were otherwise the same in content, length, instructional design, and assessment. Students in the dissection-based (Fall 2019) and prosection-based (Fall 2020) courses completed a previously validated survey that used quantitative and qualitative questions to assess their feelings about the donors and the anatomy laboratory experience. Students in both cohorts reported overall appreciation for having had the experience. Negative themes experienced by both groups included feeling anxiety, worries about depersonalizing donors, and physical discomfort in the laboratory. Students in the dissection course reported stronger connections with the donors and the donors' families but also more frequently felt negative feelings such as disgust, anxiety, and feeling alone. Students in the prosection course reported more consistently positive responses but worried about not using the donors to the fullest extent possible. Regardless of pedagogical design, students have complex emotional experiences in the anatomy laboratory and our results indicate that these feelings may be more intense in the context of dissection. Anatomists should foster educational settings that enable students to learn to process complex or challenging emotions.

Comparing autism phenotypes in children born extremely preterm and born at term.

Children born preterm are at increased risk for autism spectrum disorder (ASD). There is limited knowledge about whether ASD phenotypes in children born preterm differ from children born at term. The objective of this study was to compare ASD core symptoms and associated characteristics among extremely preterm (EP) and term-born children with ASD. EP participants (n = 59) from the Extremely Low Gestational Age Newborn Study who met diagnostic criteria for ASD at approximately 10 years of age were matched with term-born participants from the Simons Simplex Collection on age, sex, spoken language level, and nonverbal IQ. Core ASD symptomatology was evaluated with the Autism Diagnostic Interview-Revised (ADI-R) and the Autism Diagnostic Observation Schedule (ADOS). Developmental milestones, anthropometrics, seizure disorder, and psychiatric symptoms were also investigated. The EP group had lower parent-reported symptom scores on ADI-R verbal communication, specifically stereotyped language, and restricted, repetitive behaviors. There were no between-group differences on ADI-R nonverbal communication and ADI-R reciprocal social interaction or with direct observation on the ADOS-2. The EP group was more likely to have delayed speech milestones and lower physical growth parameters. Results from female-only analyses were similar to those from whole-group analyses. In sum, behavioral presentation was similar between EP and IQ- and sex-matched term-born children assessed at age 10 years, with the exception of less severe retrospectively reported stereotyped behaviors, lower physical growth parameters, and increased delays in language milestones among EP-born children with ASD.

Racial Differences in Patient Satisfaction With the Hospital Experience Undergoing Primary Unilateral Hip and Knee Arthroplasty: A Retrospective Study.

Background: Press Ganey (PG) inpatient survey is widely used to track patient satisfaction with the hospital experience. Our aim was to use the PG survey to determine if there are racial differences in overall hospital experience and perception of nurses and surgeons following hip and knee arthroplasty. Methods: We retrospectively analyzed Black and White patients from hip and knee arthroplasty registries from a single institution between July 2010 and February 2012. The overall assessment score for the hospital experience and perception of the nurse and surgeon questions from the PG inpatient survey were dichotomized as "not completely satisfied" or "completely satisfied". Multivariable logistic regression models were developed to determine the impact of race on the likelihood of being 'completely satisfied' in the hip and knee cohorts. Results: There were 2517 hip and 2114 knee patients who underwent surgery and completed the PG survey, of whom 3.9% were Black and 96.0% were White. Black patients were less likely to be completely satisfied with their hospital experience compared to White patients in the hip (odds ratio 0.62, confidence interval 0.39-1.00, P = .049) and knee (odds ratio 0.52, confidence interval 0.33-0.82, P = .005) cohorts. Black patients were also less likely to be completely satisfied with multiple aspects of care they received from the nurse and surgeon in both cohorts. Conclusions: We found that the PG Survey shows Black patients were less likely to be completely satisfied than White patients with the hospital experience, including their interactions with nurses and surgeons. More work is needed to understand this difference.

Cardiac medication prescribing and adherence after acute myocardial infarction in Chinese and South Asian Canadian patients.

BACKGROUND: Failure to adhere to cardiac medications after acute myocardial infarction (AMI) is associated with increased mortality. Language barriers and preference for traditional medications may predispose certain ethnic groups at high risk for non-adherence. We compared prescribing and adherence to ACE-inhibitors (ACEI), beta-blockers (BB), and statins following AMI among elderly Chinese, South Asian, and Non-Asian patients. METHODS: Retrospective-cohort study of elderly AMI survivors (1995-2002) using administrative data from British Columbia. AMI cases and ethnicity were identified using validated ICD-9/10 coding and surname algorithms, respectively. Medication adherence was assessed using the 'proportion of days covered' (PDC) metric with a PDC ≥ 0.80 indicating optimal adherence. The independent effect of ethnicity on adherence was assessed using multivariable modeling, adjusting for socio-demographic and clinical characteristics. RESULTS: There were 9926 elderly AMI survivors (258 Chinese, 511 South Asian patients). More Chinese patients were prescribed BBs (79.7% vs. 73.1%, p = 0.04) and more South Asian patients were prescribed statins (73.5% vs. 65.2%, p = 0.001). Both Chinese (Odds Ratio [OR] 0.53; 95%CI, 0.39-0.73; p < 0.0001) and South Asian (OR 0.78; 95%CI, 0.61-0.99; p = 0.04) patients were less adherent to ACEI compared to Non-Asian patients. South Asian patients were more adherent to BBs (OR 1.3; 95%CI, 1.04-1.62; p = 0.02). There was no difference in prescribing of ACEI, nor adherence to statins among the ethnicities. CONCLUSION: Despite a higher likelihood of being prescribed evidence-based therapies following AMI, Chinese and South Asian patients were less likely to adhere to ACEI compared to their Non-Asian counterparts.

The impact of Charlson and Elixhauser comorbidities on patient outcomes following shoulder arthroplasty.

AIMS: To investigate the impact of the Charlson and Elixhauser comorbidity indices on patient-reported outcomes measures (PROMs) following shoulder arthroplasty. METHODS: Patients undergoing total shoulder arthroplasty (TSA), reverse shoulder arthroplasty (RSA), or hemiarthroplasty (HA) from 2016 to 2018 were identified, along with the Charlson and Elixhauser comorbidities listed as their secondary diagnoses in the electronic medical records. Patients were matched to our institution's registry to obtain their PROMs, including shoulder-specific (American Shoulder and Elbow Society (ASES) and Shoulder Activity Scale (SAS)) and general health scales (12-Item Short Form Survey (SF-12) and Patient-Reported Outcomes Measurement Information System-Pain Interference). Linear regression models adjusting for age and sex were used to evaluate the association between increasing number of comorbidities and PROM scores. A total of 1,817 shoulder arthroplasties were performed: 1,017 (56%) TSA, 726 (40%) RSA, and 74 (4%) HA. The mean age was 67 years (SD 10), and 936 (52%) of the patients were female. RESULTS: The most common comorbidities were obesity (1,256, 69%) and hypertension (990, 55%). Patients with more comorbidities had lower ASES and SAS scores at baseline (p < 0.001). Elixhauser comorbidities continued to negatively impact ASES and SAS scores at one year (p = 0.002) and two-year follow-up (p = 0.002). Patients with more comorbidities reported greater pain interference on PROMIS at baseline (p = 0.007), but not at two years. Higher number of Charlson comorbidities were associated with lower scores on the SF-12 mental component at baseline (p < 0.001) and two years (p = 0.020). Higher number of Elixhauser comorbidities were associated with lower SF-12 physical component scores at baseline (p < 0.001) and two years (p = 0.004). CONCLUSION: Higher number of comorbidities was associated with lower baseline scores and worse outcomes on both shoulder-specific and general health PROMs. The presence of specific comorbidities may be used during shared decision-making to manage expectations for patients undergoing shoulder arthroplasty.

Breastfeeding and Risk of Late-Onset Group B Streptococcal Disease.

BACKGROUND: Group B Streptococcus (GBS) is a major contributor to neonatal sepsis worldwide. Late-onset group B Streptococcus disease (LOGBS) and its risk factors remain poorly understood. The isolation of GBS from breast milk has been described in cases of LOGBS. This potential association has raised concerns for mothers and clinicians regarding the safety of ongoing breastfeeding. In this study, we aimed to investigate whether exposure to breast milk is associated with increased risk of LOGBS. METHODS: A case-control study of LOGBS was conducted across 4 hospital networks in Victoria, Australia, including the 2 major tertiary pediatric centers in the state, to evaluate 11 years of data (2007-2017). Cases were captured initially from microbiology databases and recaptured with International Classification of Diseases discharge coding. Each case patient was matched with 4 controls to assess feeding status. Patients were matched for chronological age, gestation, discharge status, recruitment site, and calendar year. RESULTS: We identified 92 cases of LOGBS: 73 cases on initial capture and 76 cases on the recapture analysis. Case patients were matched with 368 controls: 4 controls to each patient. Seventy-two patients were exposed to breast milk at the time of LOGBS (78.3%), compared with 274 controls (74.5%; odds ratio 1.2 [95% confidence interval 0.7-2.3]). CONCLUSIONS: Breastfeeding was not associated with increased risk of LOGBS. Breast milk should not be tested for GBS during a first episode of LOGBS.

Influence of age on Salvia divinorum use: results of an Internet survey.

An Internet-based survey of Salvia divinorum ("salvia") users was conducted to identify correlates surrounding its use. Salvia-knowledgeable persons were recruited via "social networking Internet websites" (n = 23) where notices were posted on recreational salvia group message boards (n = 69). Data collection included demographics, use circumstances, experiences, and age (current and at first salvia use). A total of 219 surveys were analyzed. Salvia users who were young adults (< or = 21 yrs) at first use favored salvia for fun (OR = 1.94, CI = 1.08-3.49, p = 0.03) or to relieve boredom (OR = 2.06 CI = 1.09-3.91, p = 0.02), while salvia users who were adults (> or = 22 yrs) at first use favored salvia for spiritual effects (OR = 2.63, CI = 1.02-6.75, p = 0.04). Being an adult at first use was associated with higher odds of concurrent marijuana (OR = 2.68, CI = 1.50-4.78, p = 0.0007) or tobacco use (OR = 1.94, CI = 1.05-3.60, p = 0.03). Over half of all respondents reported use reduction or cessation in the past 12 months (114 of 219, 52%), citing dislike of the high (33.3%) or loss of interest in salvia (28.9%). Reports of cessation suggest salvia use may be more attributed to curiosity than continual abuse.

Racial Disparities in Total Knee Replacement Failure As Related to Poverty.

OBJECTIVE: To determine whether racial disparities in total knee replacement (TKR) failure are explained by poverty. METHODS: Black and white New York state residents, enrolled in a prospective single-institution TKR registry January 1, 2008 to February 6, 2012, who underwent primary unilateral TKR (n = 4,062) were linked to the New York Statewide Planning and Research Cooperative System database (January 1, 2008 to December 31, 2014) to capture revisions performed at outside institutions. Patients were linked by geocoded addresses to residential census tracts. Multivariable Cox regression was used to assess predictors of TKR revision. Multivariable logistic regression was used to analyze predictors of TKR failure, defined as TKR revision in New York state ≤2 years after surgery, or as Hospital for Special Surgery (HSS) TKR quality of life score "not improved" or "worsened" 2 years after surgery. RESULTS: The mean ± SD age was 68.4 ± 10 years, 64% of patients were female, 8% lived in census tracts with >20% of the population under the poverty line, and 9% were black. Median follow-up time was 5.3 years. A total of 3% of patients (122 of 4,062) required revision a median 454 days (interquartile range 215-829) after surgery. TKR revision risk was higher in blacks than whites, with a hazard ratio of 1.69 (95% confidence interval 1.01-2.81), but in multivariable analysis, only younger age, male sex, and constrained prosthesis were predictors of TKR revision. TKR failure occurred in 200 of 2,832 cases (7%) with 2-year surveys. Risk factors for TKR failure were non-osteoarthritis TKR indication, low surgeon volume, and low HSS Expectations Survey score, but not black race. Community poverty was not associated with TKR revision or failure. CONCLUSION: There was a trend toward higher TKR revision risk in blacks, but poverty did not modify the relationship between race and TKR revision or failure.

Effectiveness of Splanchnic Nerve Neurolysis for Targeting Location of Cancer Pain: Using the Pain Drawing as an Outcome Variable.

The effectiveness of splanchnic nerve neurolysis (SNN) for cancer-related abdominal pain has been investigated using numeric pain intensity rating as an outcome variable. The outcome variable in this study used the grid method for obtaining a targeted pain drawing score on 60 patients with pain from pancreatic or gastro-intestinal primary cancers or metastatic disease to the abdominal region. Results demonstrate excellent inter-rater agreement (intra-class correlation [ICC] coefficient at pre-SNN = 0.97 and ICC at within one month post-SNN = 0.98) for the grid method of scoring the pain drawing and demonstrate psychometric generalizability among patients with cancer-related pain. Using the Wilcoxon signed rank test and associated effect sizes, results show significant improvement in dispersion of pain following SNN. Effect sizes for the difference in pre-SNN to 2 post-SNN time points were higher for the pain drawing than for pain intensity rating. Specifically, the effect size difference from pre- to within one month post-SNN was r = 0.42 for pain drawing versus r = 0.23 for pain intensity rating. Based on a smaller subset of patients who were seen within 1 - 6 months following SNN, the effect size difference from pre-SNN was r = 0.46 for pain drawing versus r = 0.00 for pain intensity rating. Collectively, these data support the use of the pain drawing as a reliable outcome measure among patients with cancer pain for procedures such as SNN that target specific location and dispersion of pain.

Differentiation of Illusory and True Halo in Writing Scores.

This report summarizes an empirical study that addresses two related topics within the context of writing assessment-illusory halo and how much unique information is provided by multiple analytic scores. Specifically, we address the issue of whether unique information is provided by analytic scores assigned to student writing, beyond what is depicted by holistic scores, and to what degree multiple analytic scores assigned by a single rater display evidence of illusory halo. To that end, we analyze student responses to an expository writing prompt that were scored by six groups of raters-four groups assigned single analytic scores, one group assigned multiple analytic scores, and one group assigned holistic scores-using structural equation modeling. Our results suggest that there is evidence of illusory halo when raters assign multiple analytic scores to a single student response and that, at best, only two factors seem to be distinguishable in analytic writing scores assigned to expository essays.

Physiologic or pathologic hypertrophy: how can we know?

Pathologic left ventricular hypertrophy due to hypertrophic cardiomyopathy is typically diagnosed based on compatible clinical and imaging findings. In a subset of patients however, the diagnosis is unclear, either due to the finding of concentric hypertrophy raising the possibility of physiologic hypertrophy due to athlete's heart or due to the potential of so-called hypertrophic cardiomyopathy 'phenocopies', which include Anderson-Fabry disease and cardiac amyloidosis. We review each of these diseases, highlighting important distinguishing features, the knowledge of which should permit the resolution of such diagnostic dilemmas.
