Predictors of No-Shows and Cancellations in an Outpatient Neuropsychology Clinic in a Large Healthcare System.

BACKGROUND: The purpose of this study was to evaluate potential predictors of no-shows and late cancellations in an outpatient clinic within a large healthcare system serving vulnerable communities. METHODS: Demographic data and appointment status were recorded for 537 consecutive patients scheduled for neuropsychological evaluation in an outpatient psychiatry clinic. Patients include 220 males and 317 females with an average formal education of 11.01 years (SD = 3.87) and age of 55.64 years (SD = 16.20). RESULTS: The overall rate of no-shows or late cancellations was 20%. Of the 106 patients who no-showed/late cancelled, 41% rescheduled, and of those, 23% missed or late cancelled their second appointment. No-shows and late cancellations were associated with historical/prior no-show rate, while race/ethnicity and activation of MyChart had slight impacts. CONCLUSIONS: These data suggest that prior no-show rates and MyChart access may be targets for interventions to improve show rates. This is important for the patients' gaining access to care as well as minimizing financial strains for the system and increasing wait times/delays to care for other patients.

Epidemiology and mortality of pelvic and femur fractures-a nationwide register study of 417,840 fractures in Sweden across 16 years: diverging trends for potentially lethal fractures.

Background and purpose - Fractures of the pelvis and femur are serious and potentially lethal injuries affecting primarily older, but also younger individuals. Long-term trends on incidence rates and mortality might diverge for these fractures, and few studies compare trends within a complete adult population. We investigated and compared incidence and mortality rates of pelvic, hip, femur shaft, and distal femur fractures in the Swedish adult population.Patients and methods - We analyzed data on all adult patients ≥ 18 years in Sweden with a pelvic, hip, femur shaft, or distal femur fracture, through the Swedish National Patient Register. The studied variables were fracture type, age, sex, and 1-year mortality.Results - While incidence rates for hip fracture decreased by 18% (from 280 to 229 per 105 person-years) from 2001 to 2016, incidence rates for pelvic fracture increased by 25% (from 64 to 80 per 105 person-years). Incidence rates for femur shaft and distal femur fracture remained stable at rates of 15 and 13 per 105 person-years respectively. 1-year mortality after hip fracture was 25%, i.e., higher than for pelvic, femur shaft, and distal femur fracture where mortality rates were 20-21%. Females had an almost 30% lower risk of death within 1 year after hip fracture compared with males.Interpretation - Trends on fracture incidence for pelvic and femur fractures diverged considerably in Sweden between 2001 and 2016. While incidence rates for femur fractures (hip, femur shaft, and distal femur) decreased or remained constant during the studied years, pelvic fracture incidence increased. Mortality rates were different between the fractures, with the highest mortality among patients with hip fracture.

The outcome of patients with cultured pathogens at time of nonunion surgery.

The purpose of this study is to evaluate incidence, preoperative laboratory markers, and outcomes of patients who positively cultured pathogens (PCP) at time of surgery for long bone fracture nonunion. Two-hundred and eighty-eight patients were enrolled in a trauma study on long bone nonunion. Two-hundred and sixteen of those 288 patients were cultured at the time of fracture nonunion surgery. Laboratory data were collected prior to intervention and infectious laboratory markers ordered on patients suspected for infection. Patients were followed for one year. Wound complications, antibiotic use, healing, function, and re-admission for further surgery were assessed. Cultures returned positive on 59 patients (representing 20.5% of the 288 patient cohort or 27.3% of the 216 patients cultured in the operative suite). More PCP's (47.5%; 28 of 59) developed wound complications, with greater mean antibiotic duration and more frequent returns to the OR averaging 1.3 procedures per patient. Twelve-month follow-up was obtained on 249 of the 288 (86.5%) and PCPs reported globally worse function. Patients who PCP at the time of operative management for long bone nonunion was a prognostic indicator of poorer long-term functional outcomes.

Displaced intra-articular fractures involving the volar rim of the distal radius.

PURPOSE: To describe the features of displaced intra-articular fractures confined to the volar rim of the distal radius and compare outcomes after their operative fixation to complete intra-articular and extra-articular fractures treated with operative fixation. METHODS: A total of 627 distal radius fractures were treated over a 6-year period. Twenty-eight patients had volar rim fractures (type 23-B3, as classified by the Orthopaedic Trauma Association [OTA]), all treated with operative reduction and fixation using a volar buttress plate. Clinical outcome information including radiographs, Short Form-36 health survey, and Disabilities of the Arm, Shoulder, and Hand questionnaire were collected at regular postoperative intervals. Patients with volar rim fractures were compared with patients who sustained other types of operatively managed distal radius fractures (OTA types 23-A, 23-B1/B2, and 23-C). RESULTS: The most common type of volar rim fracture consisted of a single large fragment (OTA 23-B3.2; 46%), followed by comminuted fractures (OTA 23-B3.3; 36%). Restoration of radiographic parameters was similar between groups except for an increased volar tilt in volar rim fractures compared with group 23-B1/B2. Active wrist and finger motion improved in all groups except for wrist extension, which was less in the 23-B1/B2 groups. The 23-B1/B2 group had the greatest pain and worst Short Form-36 scores. Disabilities of the Arm, Shoulder, and Hand questionnaire scores were similar and without differences between groups. CONCLUSIONS: Our data suggest that patients with volar rim distal radius fractures can expect a rapid return to function with minimal risk for complications and have outcomes similar to other types of operatively treated distal radius fractures. Further investigation of type 23-B fractures (23-B1/B2) is warranted owing to evidence of diminished outcomes.

Are race and sex associated with the occurrence of atypical femoral fractures?

BACKGROUND: Prior studies have suggested that Asian patients and women may be more likely to sustain atypical femoral fractures in association with bisphosphonate use. However, they do not account for confounders such as asymptomatic patients who are long-term bisphosphonate users or patients sustaining osteoporotic fractures. QUESTIONS/PURPOSES: The purpose of this study was to determine the differences in sex and racial association with atypical femoral fractures by comparing demographic characteristics of patients who sustained an atypical bisphosphonate-associated fracture with patients on long-term bisphosphonates without fractures and with patients who sustained osteoporotic fractures. METHODS: Three groups from prospective registries were identified: (1) patients with atypical femur fractures associated with long-term bisphosphonate use (BFF) (n = 54); (2) patients on long-term bisphosphonates but with no associated fractures (BNF) (n = 119); and (3) patients with osteoporotic proximal femur fractures not associated with bisphosphonates (PFF) (n = 216). Age, sex, and self-reported race/ethnicity were documented and compared. Multivariate and univariate analyses were done as well as age- and sex-stratified analyses. RESULTS: Age and sex distributions of the BFF and BNF patients were similar. There was a higher percentage of Asian patients in the BFF group (17%) than in the BNF group (3%; p = 0.004) as well as Hispanics (13% versus 3% in BNF; p = 0.011). Patients in the BFF group were younger than those in the PFF group (67.5 versus 78.4 years; p < 0.001) and had fewer males (7% versus 14%; p < 0.001). CONCLUSIONS: These data suggest that Asians are at higher risk for atypical bisphosphonate-associated fractures. We recommend closer followup in Asian patients who are taking bisphosphonates. LEVEL OF EVIDENCE: Level III, prognostic study. See Guidelines for Authors for a complete description of levels of evidence.

Acute Achilles tendon ruptures between 2002-2021: sustained increased incidence, surgical decline and prolonged delay to surgery-a nationwide study of 53 688 ruptures in Sweden.

Introduction: Given the lack of consensus on optimal treatment strategies for acute Achilles tendon rupture (ATR), understanding temporal trends, treatment choice and demographic characteristics is important. Previous research suggests increasing incidence with declining surgical treatment. Current trends in Sweden are not known. Hypothesis/purpose: To assess how incidence rates, treatment trends and time from injury to surgery (TTS) of ATR have changed between 2002 and 2021 in Sweden, with particular attention to changes since 2012. Study design: Descriptive epidemiology study. Methods: We conducted a nationwide register-based study including all inpatients and outpatients ≥18 years of age with an ATR between 2002 and 2021 in Sweden. Results: 53 688 ATRs (78.5% men) were identified during the study period. 15 045 patients (81.5% men) were surgically treated within 30 days. The long-term incidence rate for ATR injury increased by 45%, from 28.8 in 2002 to 41.7 in 2021 per 100 000 person-years (p<0.0001). In the last 5 years of the study, there was a significant, continuing increase in ATR incidence by 21%, from 34.4 in 2017 to 41.7 in 2021 per 100 000 person-years (p<0.0001). The surgical incidence rates decreased from 13.4 to 6.0 per 100 000 person-years (p<0.0001). TTS increased from 0.6 days in 2002 to 5.1 in 2021 (p<0.0001). Conclusion: The observed increase in incidence rates and decrease in surgical treatment of ATR emphasise the need for evidence-based treatment and rehabilitation protocols for non-operated patients of all ages. A significant increase in time from injury to surgery was observed throughout the study period.

[Challanges and possibilities with space travel]. / Rymdmedicin: utmaningar och möjligheter med rymdfärder.

Human space flight poses several challenges to human health, such as microgravity, space radiation, and prolonged confinement. Humans are anatomically and physiologically adapted to the gravitation on earth, and microgravity affects crucial functions. We review the pathophysiological consequences of spaceflight on the sensomotoric, cardiovascular, cerebral, and musculoskeletal systems, as well as effects of space radiation and psychosocial considerations. We also look at the medical capabilities in space, and different research methods on earth and in space.

Increasing incidence of pelvic and acetabular fractures. A nationwide study of 87,308 fractures over a 16-year period in Sweden.

BACKGROUND: Fractures of the pelvis and acetabulum are major injuries, often associated with hospitalization, reduced function and sometimes life-threatening conditions. Current data on nationwide incidence and treatment is sparse. Existing epidemiological studies are either single-centered or investigating only in-patients. The aim of this study was to investigate the epidemiology and treatment of pelvic and acetabular fractures in a nationwide register study including all adult patients in Sweden during 2001-2016. METHODS: We used the Swedish National Patient Register to collect data on the entire Swedish population aged ≥18 years from 2001 to 2016. Variables included age, gender, fracture type and treatment. RESULTS: We found a total of 87,308 pelvic and acetabular fractures (71% females) in Sweden during the 16-year study period and the incidence increased from 64 to 80 per 100,000 person-years from 2001 to 2016. The incidence of pelvic fractures increased from 58 to 73 per 100,000 person-years and the majority of the patients (74%) were female. The incidence of acetabular fracture increased from 8.7 to 11 per 100,000 person years and the majority of the patients (58%) were male. Only 2.0% of all patients with a pelvic fracture were treated surgically, as compared to 15% for acetabular fractures. The rate of surgical treatment was higher for males compared to females for both pelvic (4.4 and 1.2% respectively) and acetabular (19 and 10% respectively) fractures. CONCLUSION: The incidence of pelvic and acetabular fractures increased markedly in Sweden from 2001-2016. Pelvic fractures were more common among females and acetabular among males. The surgical rate was higher for acetabular compared to pelvic fractures. Major gender differences in treatment choices were found with higherproportion of men treated surgically for both fracture types, and in all age groups.

Income change after cruciate ligament injury - A population-based study.

OBJECTIVES: To investigate the association between choice of treatment and patients' income after cruciate ligament (CL) injury and assess the effect of different covariates such as sex, age, comorbidities and type of work. METHODS: This entire-population cohort study in Sweden included working patients with a diagnosed CL injury between 2002 and 2005, identified in The National Swedish Patient Register (n = 13,662). The exposure was the treatment choice (operative or non-operative treatment). The main outcome measure was average yearly income five years after CL diagnosis, adjusted for the following covariates: sex, age, comorbidities, type of work, region, calendar year, education and income. RESULTS: Relative to non-operative treatment, operative treatment was associated with greater average yearly incomes (nine to 15%) after injury among patients between 20 and 50 years, patients with partial university education, patients living in large cities and patients with one comorbidity, despite no overall significant association in the national cohort. Delayed operative treatment (>1 year) had no significant association with income change, whereas early operative treatment (<1 year) was associated with higher average yearly incomes (11 to 16%) among females, patients between 20 and 50 years, patients living in large cities and patients with one comorbidity. CONCLUSIONS: In a broad sense, treatment choice was not associated with changes in income five years after CL injuries among patients in the workforce, however earlier operative treatment was associated with higher average incomes among patients with ages between 20 and 50, females, living in large cities, with one comorbidity and with a high level of education.

The Effect of Socioeconomic Status on the Choice of Treatment for Patients With Cruciate Ligament Injuries in the Knee: A Population-Based Cohort Study.

BACKGROUND: The socioeconomic status (SES) of patients has been widely recognized as playing an important role in many health-related conditions, including orthopaedic conditions, in which a higher SES has been associated with a higher utilization of more advanced medical treatments such as drugs, diagnostics, and surgery. However, the association between SES and cruciate ligament surgery has not been thoroughly investigated. PURPOSE: To evaluate the association between SES and choice of treatment in patients with a cruciate ligament injury. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: All Swedish patients with a diagnosed cruciate ligament injury between 1987 and 2010 were identified from the Swedish National Patient Register (N = 98,349). The Longitudinal Integration Database for Health Insurance and Labor Market Studies (LISA) provided information on household income and highest achieved educational level, which were used as socioeconomic indices. The exposure was the SES of patients as determined by the household income and educational level, and the main outcome measure was treatment choice (surgical reconstruction vs nonoperative treatment). Poisson regression models estimated the association. RESULTS: A total of 52,566 patients were included in the study; of these, 20,660 (39%) were treated operatively. Patients in the highest quartile of household income had a significantly higher likelihood of undergoing surgery than those in the lowest quartile (relative risk [RR], 1.16; 95% CI, 1.11-1.20). Patients classified as highly educated had a significantly increased likelihood of being treated operatively compared with those with a low education (RR, 1.29; 95% CI, 1.19-1.39). CONCLUSION: This study provides a population-based validation that having a higher SES as determined by the household income and/or level of education increases the likelihood of undergoing operative treatment after a cruciate ligament injury. CLINICAL RELEVANCE: All Swedish citizens are entitled by law to the same quality of health care; therefore, unmotivated differences in treatment between different socioeconomic groups are to be seen as a challenge. It is important to evaluate the specific mechanisms by which the patient's SES influences the decision of whether to treat a cruciate ligament injury operatively.

Concomitant Ulnar Styloid Fracture and Distal Radius Fracture Portend Poorer Outcome.

The literature on the effect of ulnar styloid fractures (USFs) on concomitant distal radius fractures (DRFs) is mixed. We conducted a study to determine if associated ipsilateral USFs affect outcomes of DRFs. We retrospectively evaluated 315 DRFs treated (184 operatively, 131 nonoperatively) over a 7-year period. Concomitant USFs were identified. Mean follow-up was 12 months. Disabilities of the Arm, Shoulder, and Hand (DASH) and 36-Item Short Form Health Survey (SF-36) outcome scores, and grip strength and wrist range of motion data, were collected. Statistical analysis was performed with Student t test and analysis of variance. Incidence of concomitant USF and DRF was higher (P < .0002) in the operative group (64.6%) than in the nonoperative group (39.1%). Patients with USFs had worse mean (SD) pain score, 1.80 (2.43) versus 0.80 (1.55) (P = .0001), DASH score, 17.03 (18.94) versus 9.21 (14.06) (P = .001), and SF-36 score, 77.16 (17.69) versus 82.68 (16.10) (P = .022). In the operative group, patients with USFs had more pain and poorer DASH Functional scores than patients without USFs. Results were similar in the nonoperative group. There was no difference in healing time between intra-articular and extra-articular fractures or between presence and absence of USFs. Concomitant occurrence of USFs and DRFs-which is associated with worse pain scores and lower functioning compared with USFs without DRFs-should prompt clinicians to counsel patients about delayed recovery.

Are Locked Plates Needed for Split Depression Tibial Plateau Fractures?

Displaced tibial plateau fractures often require surgical treatment and plate and screw constructs are the most common method of fixation. There has been increased usage of locking plate technology for both complex and simple fracture patterns without any evidence demonstrating their advantage. The purpose of this study was to compare the clinical use of locked versus nonlocked plating for repair of displaced Schatzker type-II (OTA Type 41B) tibial plateau fractures. Seventy-seven consecutive patients treated operatively with one of two types of plate and screw constructs in a nonrandomized fashion for Schatzker type II tibial plateau fractures and they were prospectively followed over a 5-year period. A total of 35 (45.5%) patients were treated using a locked plate and screw construct and 42 (54.5%) patients were treated with a nonlocked plate and screw construct. All patients received the same pre- and postoperative care and there was no difference in plate morphology and length between cohorts. Clinical outcomes were assessed using Short Musculoskeletal Functional Assessment (SMFA) scores, Visual Analogue Score for pain, and knee ranges of motion. Radiographic outcome was assessed with plain radiographs at all follow-up points. Implant costs for both types of constructs were calculated from hospital purchasing records. Patients were assessed at a mean period of 18.5 months (range: 12-72 months). There was no difference in demographic factors, physical examination parameters, radiographic outcomes, and SMFA scores between cohorts. In terms of cost, the cost of locked construct was $905 more than the nonlocked construct. Based on clinical outcomes and cost per implant, we found no evidence to support the routine use of locked plating for simple split depression fractures of the lateral tibial plateau. The use of standard nonlocked, precontoured implants provides adequate fixation for these fracture patterns.

Nature's wrath-The effect of weather on pain following orthopaedic trauma.

BACKGROUND: Despite frequent complaints by orthopaedic trauma patients, to our knowledge there is no data regarding weather's effect on pain and function following acute and chronic fracture. The aim of our study was to investigate the influence of daily weather conditions on patient reported pain and functional status. METHODS: We retrospectively examined prospectively collected data from 2369 separate outpatient visits of patients recovering from operative management of acute tibial plateau fractures, acute distal radius fractures, and chronic fracture nonunions. Pain and functional status were assessed using a visual analogue scale (VAS) and the DASH and SMFA functional indexes. For each visit date, the mean temperature, difference between mean temperature and expected temperature, dew point, mean humidity, amount of rain, amount of snow, and barometric pressure were recorded. Statistical analysis was run to search for associations between weather data and patient reported pain and function. RESULTS: Low barometric pressure was associated with increased pain across all patient visits (p=0.007) and for patients at 1-year follow-up only (p=0.005). At 1-year follow-up, high temperature (p=0.021) and high humidity (p=0.030) were also associated with increased pain. No significant association was noted between weather data and patient reported functional status at any follow-up interval. CONCLUSIONS: Patient complaints of weather influencing pain after orthopaedic trauma are valid. While pain in the immediate postoperative period is most likely dominated by incisional and soft tissue injuries, as time progresses barometric pressure, temperature, and humidity impact patient pain levels. Affirming and counseling that pain may vary based on changing weather conditions can help manage patient expectations and improve satisfaction.

Pectoralis major transosseous equivalent repair with knotless anchors: Technical note and literature review.

INTRODUCTION: Rupture of the pectoralis major (PM) tendon was initially described almost 2 centuries ago, but most of the reported injuries have occurred within the last 30 years. Options for repair have varied widely. The most common methods for repair depend on either transosseous sutures or suture anchors for fixation. Transosseous suture repair allows for docking the tendon into a trough at its anatomic insertion, but risks cortical breakage during suture passing. Our experience has confirmed the value and potential advantages of anchors for a secure fixation. AIMS: To describe a variation of repair using knotless suture anchors and a burred trough to dock the tendon into its anatomic insertion. CONCLUSION: We describe a technique of a transosseous equivalent PM repair technique. To our knowledge, this is the first paper describing such a repair technique for PM rupture.

Failure of Anterior Cruciate Ligament Reconstruction.

The present review classifies and describes the multifactorial causes of anterior cruciate ligament (ACL) surgery failure, concentrating on preventing and resolving such situations. The article particularly focuses on those causes that require ACL revision due to recurrent instability, without neglecting those that affect function or produce persistent pain. Although primary ACL reconstruction has satisfactory outcome rates as high as 97%, it is important to identify the causes of failure, because satisfactory outcomes in revision surgery can drop to as much as 76%. It is often possible to identify a primary or secondary cause of ACL surgery failure; even the most meticulous planning can give rise to unexpected findings during the intervention. The adopted protocol should therefore be sufficiently flexible to adapt to the course of surgery. Preoperative patient counseling is essential. The surgeon should limit the patient's expectations for the outcome by explaining the complexity of this kind of procedure. With adequate preoperative planning, close attention to details and realistic patient expectations, ACL revision surgery may offer beneficial and satisfactory results for the patient.

Symptomatic atypical femoral fractures are related to underlying hip geometry.

The benefits of bisphosphonates are well documented, but prolonged use has been associated with atypical femur fractures. Radiographic markers for fracture predisposition could potentially aid in safer medication use. In this case-control designed study, we compared hip radiographic parameters and the demographic characteristics of chronic bisphosphonate users who sustained an atypical femoral fracture with a group of chronic bisphosphonate users who did not sustain an atypical femur fracture and also a group who sustained an intertrochanteric hip fracture. Radiographic parameters included were neck-shaft angle (NSA), hip-axis length (HAL) and center-edge angle (CE). Multivariate regression was used to evaluate the relationship between radiographic measures and femur fracture. Receiver-operating characteristic analysis determined cut-off points for neck-shaft angle and risk of atypical femur fracture. Ultimately, pre-fracture radiographs of 53 bisphosphonate users who developed atypical fracture were compared with 43 asymptomatic chronic bisphosphonate users and 64 intertrochanteric fracture patients. Duration of bisphosphonate use did not statistically differ between users sustaining atypical fracture and those without fracture (7.9 [±3.5] vs. 7.7 [±3.3] years, p=0.7). Bisphosphonate users who fractured had acute/varus pre-fracture neck-shaft angles (p<0.001), shorter hip-axis length (p<0.01), and narrower center-edge angles (p<0.01). Regression analysis revealed associations between neck-shaft angle (OR=0.89 [95% CI=0.81-0.97; p=0.01), center edge angle (OR=0.89 [95% CI=0.80-0.99]; p=0.03), and BMI (OR=1.15 [95% CI=1.02-1.31; p=0.03) with fracture development. ROC curve analysis (AUC=0.67 [95% CI=0.56-0.79]) determined that a cut-off point for neck-shaft angle <128.3° yielded 69% sensitivity and 63% specificity for development of atypical femoral fracture. Ultimately, an acute/varus angle of the femoral neck, high BMI, and narrow center-edge angle were associated with development of atypical femur fracture in long-term bisphosphonate users. Patients on long-term bisphosphonates should be regularly radiographically evaluated in order to assess for potential risk of atypical fracture.
