Effects on Gait and Balance of VIM Gamma Knife Radiosurgery in Essential Tremor.

INTRODUCTION: Essential tremor (ET) is the most common movement disorder, characterized by an action tremor in the upper limbs. Neurosurgical techniques targeting the thalamic ventrointermediate nucleus (VIM) including thermocoagulation demonstrated a potential risk for gait and posture worsening. This study evaluates the potential effect of VIM Gamma Knife radiosurgery (GKR) in ET on gait and posture performances. METHODS: We conducted a prospective study to quantitatively assess gait and balance in severe ET patients before and 1 year after unilateral GKR. Seventy-three patients were included in this series. RESULTS: First, we confirmed the unilateral GKR efficacy in severe ET patients: global tremor score and impairments in activities of daily living improved, respectively, by 67% and 71.7%. The global gait and posture analysis found no significant differences before and 1 year after GKR. Three patients (4.1%) developed mild to moderate gait and posture impairment with proprioceptive ataxia. All of these AEs were induced by a hyper-response to radiosurgery. CONCLUSIONS: Gait and posture performances were not statistically significant at the population. Nevertheless, gait and posture worsened in 4% of patients after GKR, all in the setting of hyper-response. This study shows that GKR may be a safe neurosurgical alternative to improve ADL in a population of patients with TE.

Pre-operative triAge proCedure to streaMline elective surgicAl patieNts (PACMAN) improves efficiency by selecting patients eligible for phone consultation: A retrospective cohort study.

BACKGROUND: Pre-operative screening is a high volume task consuming time and resource. Streamlining patient flow by gathering information in advance reduces costs, optimises resources and diminishes patient burden whilst maintaining safety of care. OBJECTIVE: To evaluate whether 'Pre-operative triAge proCedure to streaMline elective surgicAl patieNts' (PACMAN) is able to improve pre-operative screening by selecting patients eligible for evaluation by telephone. DESIGN: A single-centre, retrospective, observational cohort analysis. SETTING: A tertiary medical teaching hospital in 's-Hertogenbosch, The Netherlands. PATIENTS AND METHODS: Adults scheduled for clinical interventions under procedural sedation and all types of elective medium or low risk surgery with anaesthetic guidance were eligible. Patients answered a questionnaire to calculate the PACMAN score. This score combined with risk factors related to surgery determines suitability for phone consultation (PhC) or the need for an in-person consultation (in-PC). INTERVENTION: Evaluation of standard care. MAIN OUTCOME MEASURES: Primary outcome was the reduction in number of in-PCs. Secondary outcomes included reliability of PACMAN, peri-operative patient outcomes and cost-effectiveness. RESULTS: Of 965 patients triaged by PACMAN, 705 (73.1%) were identified as suitable for a PhC. Of those, 688 (97.6%) were classified American Society of Anesthesiologists Physical Status (ASA-PS) I to II or III with stable comorbidities. Of the 260 in-PC patients, 47.4% were classified ASA-PS III with unstable comorbidities or ASA-PS IV. The overall incidence of unanticipated adverse peri-operative events was 1.3%. Finally, implementation of PACMAN led to a 20% increase in pre-operative department efficiency due to better deployment of personnel and resources. CONCLUSION: Implementation of PACMAN resulted in a 73.1% reduction in pre-operative in-PCs at our hospital. Given the increasing pressure on healthcare systems globally, we suggest developing further optimisation and integration of smart triage solutions into the pre-operative process.

Effect of interprofessional and intraprofessional clinical collaboration on patient related outcomes in multimorbid older patients - a retrospective cohort study on the Intensive Collaboration Ward.

BACKGROUND: The management and care of older patients with multiple health problems is demanding and complex. Interprofessional and intraprofessional collaboration has the potential to improve both the efficiency and the quality of care for these patients. However, it has proven difficult to demonstrate the efficacy of this approach in terms of objective patient-related outcomes. Recently, a care model with interprofessional and intraprofessional care was started, the Intensive Collaboration Ward (ICW). This ward combines interprofessional care and intraprofessional care for older patients with multiple health problems. The aim of this study was to evaluate the effects of ICW care in older patients with multiple health problems. METHODS: This retrospective cohort study evaluated the effects on patients outcomes. This was done by comparing patients of the new model, the ICW (ICW group), to a historical cohort of comparable patients who would have been eligible for the ICW (control group). Outcomes were medical consultations, allied health professional consultations, radiological procedures, waiting time for radiological procedures, change in primary treating specialty, length of hospital stay, readmission rate, and mortality rate. Linear and logistic regression analyses were performed, adjusted for baseline differences. RESULTS: The ICW group required significantly fewer medical consultations than the control group. Calls to specialists from the emergency room decreased significantly, but there was no change in in-person consultations on the ER. 51% of control patients had ≥ 1 in-hospital consultation compared to 21% of ICW patients (p < 0.05). Patients in the ICW group received significantly more consultations with allied health professionals and more often had a change in primary treating specialty. CONCLUSIONS: Interprofessional and intraprofessional clinical collaboration on the ICW reduced in-hospital consultations and increased allied health professionals' consultations. This approach may decrease fragmentation of care and provide more integrated, efficient and patient centered care. This may improve the overall care of older patients with multiple health problems.

Combined interprofessional and intraprofessional clinical collaboration reduces length of stay and consultations: a retrospective cohort study on an intensive collaboration ward (ICW).

Patients with multiple health problems are a growing population at high risk of receiving fragmented care, resulting in a poorer quality of care, preventable hospitalisations, and higher costs. Health agencies such as the World Health Organization (WHO) advocate the implementation of interprofessional care, which should lead to better patient care. This retrospective cohort study investigated the effect of combined interprofessional and intraprofessional collaboration on the management of mainly elderly patients with multiple health problems on an Intensive Collaboration Ward (ICW). Patient health outcomes, patient experience, and the cost and value of care were assessed. In total, 200 patients admitted to the ICW were compared with 51 control patients with an indication for the ICW who were admitted to a regular ward because of a shortage of ICW beds. Patients admitted to the ICW had a shorter length of hospital stay than control patients (median 5 vs 7 days, p = .004) and had fewer in-hospital consultations (p = .003). Patient satisfaction did not differ between the ICW and control patients (mean rating (1-10) 8.22 vs 8.75, p = .060). This study indicates that interprofessional and intraprofessional clinical collaboration reduces the length of hospital stay and the number of in-hospital consultations, without affecting patient satisfaction.

Correction to: Fewer patients undergo surgery when adding a comprehensive geriatric assessment in older patients with a hip fracture.

The original version of this article unfortunately contained a mistake. The presentation of Figure 1 was incorrect. The correct version of Figure 1 is given in the following page.

Fewer patients undergo surgery when adding a comprehensive geriatric assessment in older patients with a hip fracture.

INTRODUCTION: Geriatricians have been increasingly involved in the pre-operative process in frail elderly patients with a hip fracture which can benefit re-hospitalization, post-operative functional performance, and mortality. The objective of this study was to compare the number of older patients with hip fractures who opted for non-surgical management after the addition of pre-operative comprehensive geriatric assessment (CGA) with shared decision making by a geriatrician to usual care. Secondary objectives were: reasons for non-surgical management, duration of life, and location of death. MATERIALS AND METHODS: A single-center, with a level 2 trauma center, retrospective study comparing care before and after introducing pre-operative CGA with shared decision making in September 2014. Patients ≥ 70 years with a hip fracture, admitted from January 2014 to September 2015, were included. The percentages of patients elected for non-surgical management and palliative care without or with CGA were compared. Differences in secondary objectives (age, sex, medical history, medication use, functional, and social status) were compared descriptively and qualitatively. RESULTS: With pre-operative CGA significantly more patients (or representatives) elected the non-surgical management option after hip fracture (respectively, 9.1% vs 2.7%, p = 0.008). Patient characteristics were comparable. Reported reasons not to undergo surgery include aversion to be more dependent on others, and severe dementia. CONCLUSION: The geriatrician can have an important role in decisions for non-surgical management by shared decision making in the pre-operative period in patients ≥ 70 years with a hip fracture in the emergency room.

Increase in early wound leakage in total knee arthroplasty with local infiltrative analgesia (LIA) that includes epinephrine: a retrospective cohort study.

Background and purpose - After introducing a new local infiltration anesthesia (LIA) protocol with addition of 30 mL ropivacaine 2% and 1 mg epinephrine, we noted an increase in early wound leakage. As wound leakage is associated with prosthetic joint infection, our department aims to minimize postoperative wound leakage. This study evaluates the incidence of early wound leakage and postoperative pain after knee arthroplasty (KA) following adjustment of the LIA protocol with addition of 30 cc ropivacaine 2% and 1 mg epinephrine. Patients and methods - In this retrospective medical dossier study all patients (n = 502) undergoing a primary total or unicondylar knee arthroplasty between January 1, 2018 and July 1, 2019 were included. Patients received an LIA protocol containing 120 mL 2 mg/mL ropivacaine (ROPI- group; n = 256). After October 30, patients received an LIA protocol containing 150 mL 2 mg/mL ropivacaine with 1 mg epinephrine in the first 100 mL (ROPI + group; n = 246). The primary outcome measure was early wound leakage (< 72 hours postoperatively), defined as wound fluid leaking past the barrier of the wound dressing. Secondary outcome measure, 10-point numeric rating scale (NRS) pain (< 72 hours postoperatively) was also assessed. Data was evaluated using logistic regression. Results - The incidence of wound leakage was higher in the ROPI + group: 24% versus 17% in the ROPI- group (p = 0.06). After adjusting for the differences between surgeons the relative risk of this increase was 1.4 (1.0-2.0). The ROPI + and ROPI- group were similar regarding postoperative pain assessment. Interpretation - Adjustment of the LIA protocol with 30 mL 2% ropivacaine and 1 mg epinephrine led to an increase in early wound leakage in knee arthroplasty but no difference in pain scores.

The impact of greenspace and condition of the neighbourhood on child overweight.

Background: Childhood overweight/obesity has been associated with environmental, parenting and socioeconomic status (SES) factors. This paper assesses the influence of the amount of green space, accessibility to a garden and neighbourhood condition on being overweight/obese. It investigates whether parental behaviours moderate or mediate this influence and evaluates the interaction of SES with environmental context. Methods: 6467 children from the UK Millennium Cohort Study living in England were analysed. We estimated logistic regressions to examine the initial association between environment and overweight. Subsequently, parenting determinants comprising: food consumption, physical activity, rules and regularity were evaluated as moderators or mediators. Lastly SES related variables were tested as moderators or mediators of the associations. Results: Statistically significant associations were found between low levels of green space, no access to a garden, run down area and childhood overweight/obesity [odds ratio (OR) [95% confidence interval (CI)] respectively: 1.14 (1.02-1.27), 1.35 (1.16-1.58), 1.22 (1.05-1.42)]. None of the parental constructs mediated or moderated the relationships between environment and childhood overweight/obesity. Including SES, parental education moderated the effect of environmental context. Specifically, among lower educated households lack of garden access and less green space was associated with overweight/obesity; and among higher educated households poor neighbourhood condition influenced the probability of overweight/obesity respectively: 1.38 (1.12-1.70) OR 1.38, 95% CI (1.21-1.70). Conclusions: This study suggests that limits on access to outdoor space are associated with future childhood overweight/obesity although the ways in which this occurs are moderated by parental education level.

Factors related to intentional non-initiation of bisphosphonate treatment in patients with a high fracture risk in primary care: a qualitative study.

BACKGROUND: Adherence to osteoporosis treatment is crucial for good treatment effects. However, adherence has been shown to be poor and a substantial part of the patients don't even initiate treatment. This study aimed to gain insight into the considerations of both osteoporosis patients and general practitioners (GP) concerning intentional non-initiation of bisphosphonate treatment. METHODS: Osteoporosis patients and GPs were recruited from the SALT Osteoporosis Study and a transmural fracture liaison service, both carried out in the Netherlands. Using questionnaires, we identified non-starters and starters of bisphosphonate treatment. Semi-structured interviews were conducted to gain a detailed overview of all considerations until saturation of the data was reached. Starters were asked to reflect on the considerations that were brought forward by the non-starters. Interviews were open coded and the codes were classified into main themes and subthemes using an inductive approach. RESULTS: 16 non-starters, 10 starters, and 13 GPs were interviewed. We identified three main themes: insufficient medical advice, attitudes towards medication use including concerns about side effects, and disease awareness. From patients' as well as GPs' perspective, insufficient or ambiguous information from the GP influenced the decision of the non-starters to not start bisphosphonates. In contrast, starters were either properly informed, or they collected information themselves. Patients' aversion towards medication, fear of side effects, and a low risk perception also contributed to not starting the medication, whereas starters were aware of their fracture risk and were confident of the outcome of the treatment. Concerns about osteoporosis treatment and its side effects were also expressed by several GPs. Some GPs appeared to have a limited understanding of the current osteoporosis guidelines and the indications for treatment. CONCLUSIONS: Many reasons we found for not starting bisphosphonate treatment were related to the patients or the GPs themselves being insufficiently informed. Attitudes of the GPs were shown to play a role in the decision of patients not to start treatment. Interventions need to be developed that are aimed at GPs, and at education of patients.

Adherence and persistence of patients using oral bone sparing drugs in primary care.

Aim: Studies based on pharmacy medication records have shown suboptimal adherence and persistence of osteoporosis treatment with oral bone sparing drugs (OBSD). Little is known about adherence and persistence of OBSD treatment in primary care. We assessed adherence and persistence of OBSD use of patients in general practices and identified associated factors. Methods: Using electronic medical records, adherence and persistence of newly prescribed treatment with OBSD in patients from 16 general practices was retrospectively assessed. The Medication Possession Ratio (MPR) was calculated as a proxy for adherence (MPR > 75%), persistence rates were estimated using survival analysis. Determinants of adherence and persistence using logistic regression and Cox regression analysis were assessed. Results: OBSD treatment was initiated in 957 patients. Seventy-five percent and 45% of the patients persisted OBSD treatment for one and five years, respectively. Being adherent in the first year decreased the risk of long-term non-persistence [hazard ratio (HR) 0.41; 95% confidence interval (CI) 0.3-0.57; P < 0.001]. Patients receiving the majority of their prescriptions by a specialist tended to be more non-persistent (HR 1.37; 96%; CI 0.96-1.94; P = 0.08). Adherence was 62.5% in the first year and 60.8% in the overall treatment period. Non-adherence was associated with the specialist being the main prescriber [odds ratio (OR) 3.76; 95% CI 2.43-5.82; P < 0.001] and younger age (<65 years, OR 1.44; 95% CI 1.01-2.08; P = 0.04). Conclusion: Older age of the patients and the GP prescribing the majority of medication were associated with better adherence and persistence. Good adherence in the first prescription year was associated with better persistence.

Treatment of forefoot problems in older people: a randomized clinical trial comparing podiatric treatment with standardized shoe advice.

PURPOSE: Consultations for forefoot pain are frequent in primary care, but scientific support of treatment options is scarce. The purpose of this study is to investigate the effect of podiatric treatment vs standardized advice on proper shoe characteristics and fit of shoes by means of an information leaflet for people aged 50 years and older with forefoot pain in primary care. METHODS: In this randomized controlled trial, 205 participants aged 50 years and older with hindering nontraumatic forefoot pain have been recruited at their general practitioner's office. Exclusion criteria were treatment of forefoot problem of less than 6 months' duration before inclusion, rheumatoid arthritis, and diabetic neuropathy or having pain considered not to be musculoskeletal (eg, warts). Participants received shoe advice by means of an information leaflet or podiatric care. Foot pain, foot-related dysfunction, general health, and social participation were assessed by means of questionnaires every 3 months for 1 year. Using multilevel analysis, we analyzed results at the level of (1) outcome measures, (2) the individual, and (3) the general practitioner. RESULTS: No differences were found between the 2 treatment groups. Both intervention groups showed an improvement over time in foot pain and foot-related dysfunction. CONCLUSION: This study found that shoe advice provided to patients consulting their general practitioner for forefoot pain and symptom relief resulted in outcomes similar to treatment outcomes in patients consulting a podiatrist. Based on these results, primary care physicians should be cautious when referring a patient to a podiatrist; instead, they should start by providing advice on proper characteristics and fit of shoes.

Development and evaluation of a leaflet containing shoe advice: a randomized controlled trial.

BACKGROUND: Providing advice to wear good quality shoes with appropriate fit is one of the possibilities GPs have when treating patients with foot problems. OBJECTIVES: The aims of this study are to (i) determine which shoe characteristics are important when providing shoe advice; (ii) develop a shoe advice leaflet and (iii) evaluate if women choose better shoes with the aid of the leaflet. METHODS: We performed a literature search on the effect of separate shoe characteristics on foot pathologies and kinematics and developed an information leaflet with the aid of multidisciplinary experts. The leaflet was tested in a group of women aged 50 years or over who did not receive podiatric treatment or shoe advice in the year prior to the study. The women were asked to select shoes; half of them were provided with the leaflet. Shoe characteristics were scored blinded for the condition by two podiatrists. Data were analysed using a t-test for independent measures. RESULTS: The developed leaflet contains nine shoe characteristics. A total of 57 women ranging from 54 to 86 years old (average 69) consented to participate in testing the efficacy of the leaflet. Women using the leaflet (n = 29) selected better shoes than without (P = 0.049). CONCLUSIONS: Based on a literature search and expert opinion, we have developed an information leaflet for GPs to provide as a supplement to oral shoe advice. Women using this leaflet were able to select shoes of better quality and better fit than women selecting shoes without using the leaflet.

Evaluation of the measurement properties of the Manchester foot pain and disability index.

BACKGROUND: The Manchester Foot Pain and Disability Index (MFPDI, 19 items) was developed to measure functional limitations, pain and appearance for patients with foot pain and is frequently used in both observational studies and randomised controlled trials. A Dutch version of the MFPDI was developed. The aims of this study were to evaluate all the measurement properties for the Dutch version of the MFPDI and to evaluate comparability to the original version. METHOD: The MFPDI was translated into Dutch using a forward/backward translation process. The dimensionality was evaluated using exploratory and confirmatory factor analysis. Measurement properties were evaluated per subscale according to the COSMIN taxonomy consisting of: reliability (internal consistency, test-retest reliability and measurement error), validity (structural validity, content validity and cross-cultural validity comparing the Dutch version to the English version) responsiveness and interpretation. RESULTS: The questionnaire consists of three scales, measuring foot function, foot pain and perception. The reliability of the foot function scale is acceptable (Cronbach's α > 0.7, ICC = 0.7, SEM = 2.2 on 0-18 scale). The construct validity of the function and pain scale was confirmed and only the pain scale contains one item with differential item functioning (DIF). The responsiveness of the function and pain scale is moderate when compared to anchor questions. CONCLUSION: Results using the Dutch MFPDI version can be compared to results using the original version. The foot function sub-scale (items 1-9) is a reliable and valid sub-scale. This study indicates that the use of the MFPDI as a longitudinal instrument might be problematic for measuring change in musculoskeletal foot pain due to moderate responsiveness.

Factors associated with conversion to surgical release after a steroid injection in patients with a trigger finger.

AIMS: The aim of this retrospective study was to evaluate the rate of conversion to surgical release after a steroid injection in patients with a trigger finger, and to analyze which patient- and trigger finger-related factors affect the outcome of an injection. METHODS: The medical records of 500 patients (754 fingers) treated for one or more trigger fingers with a steroid injection or with surgical release, between 1 January 2016 and 1 April 2020 with a follow-up of 12 months, were analyzed. Conversion to surgical release was recorded as an unsuccessful treatment after an injection. The effect of patient- and trigger finger-related characteristics on the outcome of an injection was assessed using stepwise manual backward multivariate logistic regression analysis. RESULTS: Treatment with an injection was unsuccessful in 230 fingers (37.9%). Female sex (odds ratio (OR) 1.87 (95% confidence interval (CI) 1.21 to 2.88)), Quinnell stage IV (OR 16.01 (95% CI 1.66 to 154.0)), heavy physical work (OR 1.60 (95% CI 0.96 to 2.67)), a third steroid injection (OR 2.02 (95% CI 1.06 to 3.88)), and having carpal tunnel syndrome (OR 1.59 (95% CI 0.98 to 2.59)) were associated with a higher risk of conversion to surgical release. In contrast, an older age (OR 0.98 (95% CI 0.96 to 0.99)), smoking (OR 0.39 (95% CI 0.24 to 0.64)), and polypharmacy (OR 0.39, CI 0.12 to 1.12) were associated with a lower risk of conversion. The regression model predicted 15.6% of the variance found for the outcome of the injection treatment (R2 > 0.25). CONCLUSION: Factors associated with a worse outcome following a steroid injection were identified and should be considered when choosing the treatment of a trigger finger. In women with a trigger finger, the choice of treatment should take into account whether there are also one or more patient- or trigger-related factors that increase the risk of conversion to surgery.Cite this article: Bone Joint J 2022;104-B(10):1142-1147.

Higher 1-year risk of implant removal for culture-positive than for culture-negative DAIR patients following 359 primary hip or knee arthroplasties.

Background and purpose: To date, the value of culture results after debridement, antibiotics, and implant retention (DAIR) for early (suspected) prosthetic joint infection (PJI) as risk indicators in terms of prosthesis retention is not clear. At the 1-year follow-up, the relative risk of prosthesis removal was determined for culture-positive and culture-negative DAIR patients after primary total hip or knee arthroplasty. The secondary aim of this work was to explore differences in patient characteristics, infection characteristics, and outcomes between these two groups. Methods: A retrospective regional registry study was performed in a group of 359 patients (positive cultures: n = 299 ; negative cultures: n = 60 ) undergoing DAIR for high suspicion of early PJI in the period from 2014 to 2019. Differences in patient characteristics, the number of deceased patients, and the number of subsequent DAIR treatments between the culture-positive and culture-negative DAIR groups were analysed using independent t  tests, Mann-Whitney U  tests, Pearson's chi-square tests, and Fisher's exact tests. Results: The overall implant survival rate following DAIR was 89 %. The relative risk of prosthesis removal was 7.4 times higher (95 % confidence interval (CI) 1.0-53.1) in the culture-positive DAIR group (37 of 299, 12.4 %) compared with the culture-negative DAIR group (1 of 60, 1.7 %). The culture-positive group had a higher body mass index ( p = 0.034 ), a rate of wound leakage of > 10  d ( p = 0.016 ), and more subsequent DAIR treatments ( p = 0.006 ). Interpretation: As implant survival results after DAIR are favourable, the threshold to perform a DAIR procedure for early (suspected) PJI should be low in order to retain the prosthesis. A DAIR procedure in the case of negative cultures does not seem to have unfavourable results in terms of prosthesis retention.

Predicting self-reported functional improvement one year after primary total knee arthroplasty using pre- and postoperative patient-reported outcome measures.

BACKGROUND: Approximately 20% of patients do not perceive functional improvement after a primary total knee arthroplasty (TKA). This study aims to assess which patient-related and clinical determinants at baseline and six months postoperative can predict lack of self-reported functional improvement at 12 months after primary TKA. METHODS: In a retrospective cohort study of 569 patients who received a primary TKA between 2015 and 2018, self-reported functional improvement, measured as ≥7 points increase in Oxford Knee Score (OKS) from baseline to 12 months postoperative, was assessed. Patient characteristics and patient-reported variables at baseline and six months postoperative were entered in a logistic regression model with manual backward elimination. RESULTS: Incidence of functional improvement in this study was 73%. Preoperative variables were no strong predictors of the outcome. An increase in pain between baseline and six months postoperative was a risk factor for not functionally improving (odds ratio (OR) 1.13 (95% confidence interval (CI) 1.03-1.23)). An improvement in knee pain and function was a protective factor for lacking functional improvement (OR 0.78 (95% CI 0.74-0.82)). The prediction model explained 44% of variance and showed good calibration and discrimination. Sensitivity and specificity were 82% and 76%, respectively. CONCLUSIONS: Using pre- and postoperative variables, a prediction model for self-reported functional improvement one year after TKA was developed. This prediction tool was easy to use at six months postoperative and allowed identification of patients at high risk for not functionally improving one year after TKA. This could facilitate early interventions directed at functional improvement after TKA.

The difference between native septic arthritis and prosthetic joint infections: A review of literature.

Current literature occasionally considers septic arthritis in native joints and prosthetic joint infections as equal pathologies. However, significant differences can be identified. The aim of this review of literature is to describe these differences in definitions, pathology, diagnostic workups, treatment strategies, and prognosis.

The Effect of a Screening and Treatment Program for the Prevention of Fractures in Older Women: A Randomized Pragmatic Trial.

Population screening for fracture risk may reduce the fracture incidence. In this randomized pragmatic trial, the SALT Osteoporosis Study (SOS), we studied whether screening for fracture risk and subsequent treatment in primary care can reduce fractures compared with usual care. A total of 11,032 women aged 65 to 90 years with ≥1 clinical risk factor for fractures were individually randomized to screening (n = 5575) or usual care (n = 5457). Participants in the screening group underwent a screening program, including bone densitometry and vertebral fracture assessment. Participants with a high 10-year fracture probability (FRAX) or a vertebral fracture were offered treatment with anti-osteoporosis medication by their general practitioner. Incident fractures as reported by questionnaires were verified with medical records. Follow-up was completed by 94% of the participants (mean follow-up = 3.7 years). Of the 5575 participants in the screening group, 1417 (25.4%) had an indication for anti-osteoporosis medication. Screening and subsequent treatment had no statistically significant effect on the primary outcome fracture (hazard ratio [HR] = 0.97; 95% confidence interval [CI] 0.87-1.08), nor on the secondary outcomes osteoporotic fractures (HR = 0.91; 95% CI 0.81-1.03), major osteoporotic fractures (HR = 0.91; 95% CI 0.80-1.04), hip fractures (HR = 0.91; 95% CI 0.71-1.15), falls (odds ratio [OR] = 0.91; 95% CI 0.72-1.15), or mortality (HR = 1.03; 95% CI 0.91-1.17). Post hoc explorative finding suggested that screening might be most effective after a recent fracture (HR = 0.65; 95% CI 0.44-0.96 for major osteoporotic fractures and HR = 0.38; 95% CI 0.18-0.79 for hip fractures). The results of this study might have been compromised by nonparticipation and medication nonadherence in the screening group. Overall, this study does not provide sufficient indications to consider screening for fracture prevention. However, we cannot exclude its clinical relevance to reduce (major) osteoporotic fractures and hip fractures because of the relatively small number of women with a treatment indication in the intervention group. © 2019 The Authors.

The Effect of an App for Day-to-Day Postoperative Care Education on Patients With Total Knee Replacement: Randomized Controlled Trial.

BACKGROUND: Patients who undergo primary Total Knee Replacement surgery (TKR) are often discharged within 1-3 days after surgery. With this relatively short length of hospital stay, a patient's self-management is a crucial factor in optimizing the outcome of their treatment. In the case of TKR, self-management primarily involves adequate pain management, followed by physiotherapy exercises and daily self-care activities. Patients are educated on all these topics by hospital staff upon discharge from the hospital but often struggle to comprehend this information due to its quantity, complexity, and the passive mode of communication used to convey it. OBJECTIVE: This study primarily aims to determine whether actively educating TKR patients with timely, day-to-day postoperative care information through an app could lead to a decrease in their level of pain compared to those who only receive standard information about their recovery through the app. In addition, physical functioning, quality of life, ability to perform physiotherapy exercises and daily self-care activities, satisfaction with information, perceived involvement by the hospital, and health care consumption were also assessed. METHODS: A multicenter randomized controlled trial was performed in five Dutch hospitals. In total, 213 patients who had undergone elective, primary, unilateral TKR participated. All patients had access to an app for their smartphone and tablet to guide them after discharge. The intervention group could unlock day-to-day information by entering a personal code. The control group only received weekly, basic information. Primary (level of pain) and secondary outcomes (physical functioning, quality of life, ability to perform physiotherapy exercises and activities of daily self-care, satisfaction with information, perceived involvement by the hospital, and health care consumption) were measured using self-reported online questionnaires. All outcomes were measured weekly in the four weeks after discharge, except for physical functioning and quality of life, which were measured at baseline and at four weeks after discharge. Data was analyzed using Student t tests, chi-square tests, and linear mixed models for repeated measures. RESULTS: In total, 114 patients were enrolled in the intervention group (IG) and 99 in the control group (CG). Four weeks after discharge, patients in the IG performed significantly better than patients in the CG on all dimensions of pain: pain at rest (mean 3.45 vs mean 4.59; P=.001), pain during activity (mean 3.99 vs mean 5.08; P<.001) and pain at night (mean 4.18 vs mean 5.21; P=.003). Additionally, significant differences were demonstrated in favor of the intervention group for all secondary outcomes. CONCLUSIONS: In the four weeks following TKR, the active and day-to-day education of patients via the app significantly decreased their level of pain and improved their physical functioning, quality of life, ability to perform physiotherapy exercises and activities of daily self-care, satisfaction with information, perceived involvement by the hospital, and health care consumption compared to standard patient education. Given the rising number of TKR patients and the increased emphasis on self-management, we suggest using an app with timely postoperative care education as a standard part of care.
