Human papillomavirus-based cervical screening and long-term cervical cancer risk: a randomised health-care policy trial in Sweden.

Human papillomavirus (HPV)-based cervical screening is a globally recommended public health policy. Randomised clinical trials find superior performance of primary HPV-based screening compared with cytology for preventing cervical cancer. However, additional evidence from real-world public health policies is needed. In preplanned secondary analysis of a randomised health-care policy trial in Sweden we aimed to evaluate which policy provided better protection against invasive cervical cancer, after two full rounds of screening. The organised cervical screening programme in the capital region of Sweden invited all women aged 30-64 years and eligible for screening to a randomised health-care policy trial of HPV-based versus cytology-based screening. During 2014-16, 395 725 eligible women were randomly assigned (non-concealed) to either policy and the invasive cervical cancer incidences over 8 years of follow-up were compared. Intention-to-screen analyses included all invited women and per-protocol analyses the women that attended baseline screening according to protocol. This trial is registered with ClinicalTrials.gov, NCT01511328. Women invited to HPV-based cervical screening had a 17% lower invasive cervical cancer risk compared with women invited to cytology (hazard ratio [HR] 0·83, 95% CI 0·70-0·98). Women participating in HPV-based screening had a 28% lower invasive cervical cancer risk compared with women participating with cytology (HR 0·72, 95% CI 0·54-0·95). Adverse events were a higher number of referrals to colposcopy with biopsy in the HPV policy (15 832 [7·5%] of 212 199 in intention to screen analyses and 9968 [9·0%] of 110 176 per protocol at baseline) than in the cytology policy (12 650 [6·9%] of 183 120 in intention to screen analyses, and 7179 [7·9%] of 90 821 per protocol at baseline). Women who were HPV-negative at baseline had invasive cervical cancer risks of 1·3 (95% CI 0·6-2·4) per 100 000 person-years, whereas the risk for women with normal cytology was 9·1 (6·7-11·8) per 100 000 person-years. HPV-positive women with negative cytology triage had invasive cervical cancer risks of 79·2 per 100 000 person-years and HPV 16 or HPV 18-positive women with negative cytology triage had risks of 318·2 per 100 000 person-years. This randomised policy trial found HPV-based screening to be superior for preventing invasive cervical cancer in the real-world setting. A single baseline HPV-negative test was associated with a very low invasive cervical cancer risk after 8 years. However, HPV positivity with negative cytology triage was associated with high invasive cervical cancer risks. Region Stockholm, Swedish Cancer Society, and European Union Horizon 2020.

Health care utilization at the end of life in Parkinson’s disease: a population-based register study

BackgroundKnowledge of health care utilization at the end of life in Parkinson’s disease (PD) is sparse. This study aims to investigate end of life health care utilization, characterized by emergency room (ER) visits, receipt of specialized palliative care (SPC), and acute hospital deaths in a Swedish population-based PD cohort.MethodsWe conducted a retrospective cohort study on deceased patients (≥ 18 years) with a PD diagnosis during their last year of life (n = 922), based on health care-provider data from Region Stockholm´s data warehouse, for the study period 2015–2021. Univariable and multivariable logistic regression analyses tested associations and adjusted Odds ratios (aORs) were calculated.ResultsDuring the last month of life, approx. half of the cohort had emergency room (ER) visits and risk of frailty (measured by Hospital Frailty Risk Score) significantly predicted these visits (aOR, 3.90 (2.75–5.55)). In total, 120 people (13%) received SPC during their last three months of life, which positively associated with risk for frailty, (aOR, 2.65 (1.43–4.94, p = 0.002). In total, 284 people (31%) died in acute hospital settings. Among community-dwellers, male gender and frailty were strongly associated with acute hospital deaths (aOR, 1.90 (1.15–3.13, p = 0.01) and 3.70 (1.96–6.98, p < 0.0001)).ConclusionsRates of ER visits at end of life and hospital deaths were relatively high in this population-based cohort. Considering a high disease burden, referral to SPC at end of life was relatively low. Sex-specific disparities in health care utilization are apparent. Identifying people with high risk for frailty could assist the planning of optimal end-of-life care for people with PD.

Geographical variation in prostate cancer testing explained by socio-economic position in Stockholm

Abstract Background Prostate cancer screening using prostate-specific antigen (PSA) testing is controversial but remains prevalent in many countries. Despite its prevalence there is little information in Sweden or globally on the spatial heterogeneity in PSA testing. This study aims to describe the spatio-temporal variation in PSA testing in the Stockholm region specifically at the municipality and small area level. Additionally, it aims to quantify the extent to which socio-economic position (SEP) indicators such as education, income, and country of birth explain the observed variation in PSA testing. Methods A retrospective population-based register study was conducted, encompassing men aged 40 years and older residing in the Stockholm region from 2007 to 2016. Utilizing spatial smoothing techniques, we calculated the age-standardised proportion of men undergoing PSA testing prior to any prostate cancer diagnosis within each area for every calendar year. Furthermore, we used Bayesian logistic regression models with spatial random effects to estimate the individual-level association between PSA testing and socio-economic position. The proportion of variance in PSA testing explained by various measures of SEP was also estimated at both the municipality and small area levels. Results Significant geographical disparities in PSA testing were observed across small areas within Stockholm. The proportion of variance explained in PSA testing at the small area level was highest for income (32.6%), followed by education (9.7%) and country of birth (7.4%). Incorporating all SEP measures led to a higher proportion of explained variance at the small area level (41.6%) compared to the municipality level (24.8%). Conclusions PSA testing was significantly associated with various socio-economic indicators and some of the spatial variation could be explained by SEP. It would be useful to ascertain whether similar patterns are observed in other regions or countries. Key messages • The findings suggested widespread and consistent opportunistic prostate cancer screening practices within the Stockholm region, raising concerns regarding potential overdiagnosis and overtreatment. • The socio-economic differences in prostate cancer screening could partially explain the differences in cancer incidence and mortality.

Serious conditions among conveyed and non-conveyed patients presenting with nonspecific chief complaints to the ambulance service

BackgroundIt is a challenge for the ambulance service to identify which patients to convey to the emergency department (ED). Ideally this would be the patients with serious conditions requiring further care in the ED. However, patients presenting with non-specific chief complaints are difficult to prioritize and typically have normal or near normal vital signs despite up to one third having underlying serious conditions. The proportion of patients with serious conditions among non-conveyed patients with non-specific chief complaints (NSC) as assessed by ambulance clinicians is not known. Therefore, the primary aim was to study the proportion of serious conditions among conveyed and non-conveyed patients presenting to the ambulance service with NSCs. The secondary aim was to study the mortality rate among patients with NSCs in relation to conveyance and serious and nonserious conditions.MethodA retrospective cohort study of patients ≥ 18 years of age presenting with NSCs to the ambulance service in Stockholm Region between January 1st, 2013 and December 31st, 2013. Patients were identified via the ambulance service electronic health record and followed via records from the the National Patient Register and Causes of Death Registry at Sweden’s National Board for Health and Welfare. Descriptive statistics as well as regression analyses were used.ResultsA total of 4744 patients were included with a median age of 76 years. A serious condition was present in 1398 (29.5%) of the patients. After index assessment by the ambulance service, 3780 (79.7%) were conveyed of which 1334 (35.3%) had serious conditions, compared to 964 (20.3%) who were non-conveyed of which 64 (6.6%) had serious conditions. 30-day mortality was 372 (9.8%) in the conveyance group compared to 32 (3.3%) in the non-conveyance group. If serious conditions were present, the mortality rates were 269 (20.2%) in the conveyance group compared to 11 (17.2%) in the non-conveyance group.ConclusionThe results show that serious conditions were more than five times more common among conveyed as compared to non-conveyed patients. Mortality rates were three times higher in the conveyance group as compared to the non-conveyance group. Our results suggest that the ambulance personnel play an important role in identifying patients with serious conditions, hence, likely to be in need of treatment in the ED.Trial registrationN/A

Ascites as a Predictive Factor in Malignancies in the Last Year of Life-Comparison Between Different Cancer Types.

Background: Ascites in malignancies is usually associated with poor prognosis, but the predictive value may vary between different cancer types. Objectives: The aim was to map the frequency and temporal pattern of paracentesis in patients with malignancies in relation to time to death and to evaluate the occurrence of ascites as a predictive factor in different cancer types, with a limitation to the last year of life. Design: A retrospective study based on registry data covering all care visits in the Stockholm Region, Sweden, for seven years was performed. All deceased subjects that had at least one registered paracentesis in the last year of life were included. Results: Of 23,056 subjects dying from cancer, 1863 had undergone paracentesis in the last year of life (8.0%). Ascites requiring paracentesis was most frequently seen in appendiceal cancer (38%), ovarian cancer (35%), cholangiocarcinoma (26%), hepatocellular carcinoma (19%), and pancreatic cancer (17%). The median time for the first paracentesis in all cancer types varied between 248 and 20 days before death. For ovarian cancer, the median time for first paracentesis differed significantly compared with upper gastro-intestinal (GI) cancers, 81 days compared with 30 days (p < 0.0001). Ascites in prostate cancer was rare,1.9%, but when present, a pronounced increase in the frequency of paracentesis was observed in the last three months of life. Conclusion: The occurrence of paracentesis in patients with advanced cancer is generally a sign that death is approaching within the coming months, especially in upper GI cancer. For ovarian and appendiceal cancers, ascites is less useful as a predictive tool.

Health dialogue intervention versus opportunistic screening in primary care for type 2 diabetes and cardiovascular disease prevention in settings with low socioeconomic status (DETECT): study protocol for a pragmatic cluster-randomized trial

BackgroundMeta-analyses of randomized trials suggest that health checks and health promotion interventions targeting behavior change in primary care do not prevent cardiovascular morbidity and mortality in the general population. However, whether such interventions are more effective in high-risk populations, such as people living in low socioeconomic settings, remains unclear, as they have been poorly represented in previous trials. Therefore, we aim to evaluate the effectiveness, cost-effectiveness, and implementation of systematic screening followed by an individually oriented, lifestyle-focused, health dialogue intervention for prevention of type 2 diabetes and cardiovascular disease, as compared to opportunistic screening, in primary care in socioeconomically disadvantaged areas.MethodsUsing an overall pragmatic approach and a cluster-randomized design with two arms, we aim to enroll 3000 participants aged 50–59 years from 30 primary care centers (PCCs) with an above-average level of Care Need Index in Stockholm Region, Sweden. PCCs will be randomized (1:1) either to a health dialogue intervention, which includes inviting enlisted patients to a systematic screening of risk factors followed by an individually oriented lifestyle-focused health dialogue, or to opportunistic screening, which includes screening patients for a smaller set of risk factors during an appointment at their PCC taking place for other reasons. The main outcome will be change in systolic blood pressure during 6- and 12-month follow-ups. Additional short-term outcomes will be changes in other biological risk factors, health-related quality-of-life, and lifestyle habits, as well as process and implementation outcomes, and unintended side effects. The long-term effect on type 2 diabetes and cardiovascular disease incidence and mortality will be examined using regional and nationwide registers. Changes in systolic blood pressure and other health outcomes will be analyzed using mixed-effect generalized linear modeling and mixed-effect Cox regression to capture variability between and within PCCs. A health economic evaluation will assess resource use and costs in the short- and long-term.DiscussionThis trial of lifestyle-focused health dialogues and opportunistic screening in primary care in socioeconomically disadvantaged areas in the largest region of Sweden has the potential to yield valuable insights that could support evidence-based policymaking.Trial registrationClinicalTrials.gov (NCT06067178).

Tick-borne Encephalitis Clinical Characteristics in Adult Patients: A 10-year Retrospective Study in Stockholm, Sweden.

The incidence of Tick-borne encephalitis (TBE) has increased during the last decades in Europe. Our aim was to assess the clinical characteristics and outcome of TBE patients in Region Stockholm, as a high-risk area in Sweden. The notification database at the regional Department of Communicable Disease Control and Prevention was used to identify TBE cases during 2006-2015. Clinical data was retrieved from the included patients' medical records. The associations of specific variables to predefined outcomes of disease severity were evaluated with multivariate logistic regression models. Of 1004 identified TBE cases, 703 adult patients were included. Sixty-one percent were men, and the median age was 50 years (range 18-94). The majority were non-vaccinated. Comorbidity was present in 34%, and 4% had immunomodulatory therapy. Seventy-five percent were hospitalised, and 11% had severe disease. More than 70% of the 79 patients followed up for more than 6 months had persisting symptoms. The case fatality rate was 1.4%, with 15% in the group with immunomodulatory treatment. In the multivariate analysis, severe disease was associated with underlying comorbidities, age ≥50 years, and previous complete TBE vaccination. This is the largest cohort of TBE patients in Scandinavia. Our findings of a more severe course of disease in patients of older age, with immunomodulatory therapy, with comorbidities, and vaccination breakthrough infections must be interpreted in the context of hospitalised patients. Optimised prevention is needed for patients with immunomodulatory therapy, given the considerable case fatality rate. Follow-up visits and rehabilitation should be better standardised.

Estimation of efficacy of a home monitoring and communication platform to prevent frailty among older adults in Sweden- a pilot study with a randomized controlled trial design

BackgroundThe aging population of the world is increasing. Aging leads to risks for frailty and other chronic diseases and health systems must focus more on prevention to guarantee healthy aging. The primary objective was to estimate the efficacy of the POSITIVE-(The Maintaining and imPrOving the intrinSIc capaciTy Involving Primary Care and caregiVErs) system in improving frailty during a 6-month follow-up period. MethodA randomized controlled, assessor-blinded pilot study (RCT) with 50 individual < 70 years, pre-frail or frail was recruited from a primary care center in Stockholm Region. All participants received a drug review, nutritional recommendations, and a Vivifrail physical exercise program. In addition, the intervention group received POSITIVE including a tablet, an application, and portable measurement devices. The intervention group was monitored remotely by a primary care nurse at the primary health care centre during a six-month follow-up period. ResultsAt baseline there was a significance between the groups regarding the FTS-5 scale, and significantly more obese participants in the intervention group. The drug reviews showed that three of 43 participants got a review and new diseases were discovered. The test of interactions showed a tendency for significant differences over time between the groups in frailty measured by Fried Frailty Phenotype's and FTS-5 scales. ConclusionFrailty status over time in the intervention group not differed significantly from the controls. Including individuals to the project even through a pandemic showing that the design is possible for future studies to show effects of new ways of preventing frailty at home.

Randomized Invitation to Systematic NT-proBNP and ECG Screening in 75-Year Olds to Detect Atrial Fibrillation -STROKESTOP II.

Background: Guidelines have suggested screening for atrial fibrillation to enable early treatment and avoid downstream negative clinical events. We aimed to determine if atrial fibrillation screening potentially enhanced by NT-proBNP would reduce stroke or systemic embolism incidence as compared to in a control group and to determine if it was safe for those with low NT-proBNP concentrations to forfeit prolonged screening. Methods: In this randomized controlled trial all 75/76-year-old individuals in Stockholm Region, Sweden were randomized 1:1 to be invited to screening or serve as a control group. NT-proBNP concentration were measured and a single-lead-ECG registered only once if NT-proBNP<125ng/L, whereas if NT-proBNP≥125 ng/L participants underwent prolonged screening, recording single-lead ECGs four times daily for two weeks. If atrial fibrillation was detected, treatment was initiated. Baseline and outcome data were collected from Swedish National Registries. Results: In total 28,712 individuals were randomized, after exclusion of death and emigration 13,905 remained in the intervention group, 13,884 in the control group. Participation rate in the intervention group was 49.2% (6,843/13,905). Participants in the high NT-proBNP group (NT-proBNP≥125 ng/L) without prior atrial fibrillation constituted 60% of the total and underwent prolonged screening. New AF was detected in 2.4% (165/6,843) in the intervention group. There was no difference in AF prevalence or oral anticoagulant treatment between the intervention and the control group after five years follow-up. After a median of 5.1 years (IQR 5.0-5.8) there was no difference in the primary outcome of stroke or systemic embolism between the intervention group and the control group, HR: 0.96 (95% CI 0.86-1.06). The low NT-proBNP-group had significantly fewer strokes or systemic emboli than the control group, HR: 0.59 (95% CI 0.46-0.74), p<0.001. In the high NT-proBNP group the risk of stroke or systemic embolism was higher compared to the low NT-proBNP group, HR: 1.57 (95% CI 1.22-2.02), p=0.001. Conclusions: In this population-based screening trial for atrial fibrillation using NT-proBNP for screening enhancement, there was no difference in risk of stroke or systemic embolism for the intervention group compared to controls. Participation was moderate. The use of NT-proBNP for screening enhancement was safe in identifying low-risk participants. Clinical Trial Registration: www.clinicaltrials.gov; NCT02743416.

Long-term oncological outcomes after multimodal treatment for locally advanced prostate cancer.

The aim of this study is to evaluate treatment patterns and long-term oncological outcomes of patients with locally advanced prostate cancer (LAPCa). This is a population-based study including LAPC (cT3-4, M0) patients from the Stockholm region (Sweden). A sub-analysis was performed in men treated with primary cystoprostatectomy or total pelvic exenteration (TPE) for cT4 prostate cancer (PCa).Cox regression was used to identify predictors of overall mortality (OM) and cancer-specific mortality (CSM). Biochemical progression-free survival (BPFS) and 90 days complications were reported for the radical surgery subgroup. We included 2921 patients with cT3(N= 2713) or cT4(N= 208), M0 PCa diagnosed between 2003 and 2019. Out of these, 249(9%), 1497(51%) and 1175(40%) underwent radical prostatectomy, RT + ADT and androgen deprivation therapy (ADT), respectively. Survival rates were 76% (IQR: 68, 83), 47% (IQR: 44, 50) and 23% (IQR: 20, 27), respectively at 10years. Irrespective of treatment modalities, cT4 patients had worse survival compared to cT3 patients (OM: HR1.44, IQR:1.17,1.77; PCSM: HR1.39, IQR:1.06,1.82). Twenty-seven patients with cT4, N0-1, M0 were treated with cystoprostatectomy or TPE. Twenty-two patients (81.5%) received neoadjuvant ADT. The 5-year BPFS, CSS and OS rates were 39.6%, 68.8% and 63.8%, respectively. Nine patients (33.3%) had Clavien-Dindo grade III and 1 (3.7%) grade IV complication within 90 days after surgery. Pelvic surgery with radical intent as part of a multidisciplinary management may be an effective alternative for selected patients with locally advanced PCa leading to local tumour control and an acceptable morbidity.

Dysglycaemia screening and its prognostic impact in patients with coronary artery disease: experiences from the EUROASPIRE IV and V cohort studies

Glucose perturbations can be detected by fasting plasma glucose (FPG), HbA1c, and the oral glucose tolerance test (OGTT). The highest yield is provided by OGTT. HbA1c is considered more practical. We compare the diagnostic and predictive performance of these glycaemic indicators based on combined data from the EUROASPIRE IV (EAIV) and V (EAV) studies. This cohort study was conducted in 79 centres in 24 European countries (EAIV) and 131 centres in 27 European countries (EAV). Eligible patients were aged 18-80 years, did not have diabetes, and were diagnosed with coronary artery disease 6-36 months (EAIV) or 6-24 months (EAV) before the investigation. Patients were investigated with OGTT (FPG and 2 h post-load glucose [2-hPG]) and HbA1c. Follow-up of subsequent cardiovascular events was done by means of a questionnaire at least 1 year after the baseline investigation. Analyses were done in patients with both OGTT and HbA1c data available. Outcome analysis in these patients was restricted to those with valid follow-up data available. 16 259 patients were interviewed in EAIV (2012-13) and EAV (2016-17). 8364 patients had both OGTT and HbA1C data and were included in the analysis population (3932 in EAIV and 4432 in EAV). Information on cardiovascular events was available in 7892 patients. Follow-up was for a median 1·6 years (IQR 1·2-2·0). The average patient age was 63·3 years (SD 9·8), and 6346 (75·9%) of 8364 patients were men. At baseline, 1856 (22·5%) of 8263 patients were determined to have newly detected type 2 diabetes using OGTT alone, compared with 346 (4·2%) using HbA1c alone. New dysglycaemia, defined as newly detected type 2 diabetes or impaired glucose tolerance (IGT), was present in 3896 (47·1%) of the patients according to 2hPG. 2hPG 9 mmol/L or greater (162 mg/dL, adjusted hazard ratio [aHR] 1·58; 95% CI 1·27-1·95, p<0·0001), and HbA1c 5·9% or greater (41 mmol/mol, aHR 1·48, 1·19-1·84; p=0·0010) were the strongest predictors of cardiovascular events, while FPG did not predict. A multivariable model showed that the effect of HbA1c on cardiovascular events was mainly explained by 2hPG (aHR for 1 unit increase in HbA1c 1·13, 0·98-1·30; p=0·11; and aHR for 1 unit increase in Ln[2hPG] 1·37, 1·08-1·74; p=0·0042). 2hPG appears better than HbA1c in detecting dysglycaemia and predicting its impact on future cardiovascular events in patients with coronary artery disease and should be recommended as the primary screening tool.

GLP-1RA vs DPP-4i Use and Rates of Hyperkalemia and RAS Blockade Discontinuation in Type 2 Diabetes

Hyperkalemia is a common complication in people with type 2 diabetes (T2D) that may limit the use of guideline-recommended renin-angiotensin system inhibitors (RASis). Emerging evidence suggests that glucagon-like peptide-1 receptor agonists (GLP-1RAs) increase urinary potassium excretion, which may translate into reduced hyperkalemia risk. To compare rates of hyperkalemia and RASi persistence among new users of GLP-1RAs vs dipeptidyl peptidase-4 inhibitors (DPP-4is). This cohort study included all adults with T2D in the region of Stockholm, Sweden, who initiated GLP-1RA or DPP-4i treatment between January 1, 2008, and December 31, 2021. Analyses were conducted between October 1, 2023, and April 29, 2024. GLP-1RAs or DPP-4is. The primary study outcome was time to any hyperkalemia (potassium level >5.0 mEq/L) and moderate to severe (potassium level >5.5 mEq/L) hyperkalemia. Time to discontinuation of RASi use among individuals using RASis at baseline was assessed. Inverse probability of treatment weights served to balance more than 70 identified confounders. Marginal structure models were used to estimate per-protocol hazard ratios (HRs). A total of 33 280 individuals (13 633 using GLP-1RAs and 19 647 using DPP-4is; mean [SD] age, 63.7 [12.6] years; 19 853 [59.7%] male) were included. The median (IQR) time receiving treatment was 3.9 (1.0-10.9) months. Compared with DPP-4i use, GLP-1RA use was associated with a lower rate of any hyperkalemia (HR, 0.61; 95% CI, 0.50-0.76) and moderate to severe (HR, 0.52; 95% CI, 0.28-0.84) hyperkalemia. Of 21 751 participants who were using RASis, 1381 discontinued this therapy. The use of GLP-1RAs vs DPP-4is was associated with a lower rate of RASi discontinuation (HR, 0.89; 95% CI, 0.82-0.97). Results were consistent in intention-to-treat analyses and across strata of age, sex, cardiovascular comorbidity, and baseline kidney function. In this study of patients with T2D managed in routine clinical care, the use of GLP-1RAs was associated with lower rates of hyperkalemia and sustained RASi use compared with DPP-4i use. These findings suggest that GLP-1RA treatment may enable wider use of guideline-recommended medications and contribute to clinical outcomes in this population.

Between principles and pragmatism – primary healthcare and social services professionals’ experiences and perceptions of self-care for older adults with home care: a qualitative study

Objective To explore the experiences of healthcare and social services professionals and their perceptions of using Certificate for self-care with support (CSS) for preventive self-care for older adults with home care, including the CSS process and collaborations between primary healthcare and social services. Design An inductive qualitative study including seven focus group interviews analyzed with reflexive thematic analysis. Setting and subjects The study was conducted in the Stockholm Region 2022/23. In total, 23 informants were recruited from four key partners involved in the CSS process: professionals from primary care rehabilitation and primary healthcare, social services officers, and home care staff. Result The analyses resulted in five interconnected themes: ‘Guidelines with scope for interpretation,’ ‘Support for self-care is needed, but complicated in practice,’ ‘To trust the other professions’ competence,’ ‘There is a transfer of responsibility,’ and ‘Communication is key.’ The overarching theme ‘Principles or pragmatism for safe person-centered care,’ anchoring the other themes, revealed a common goal of achieving safe and individualized care within available resources, but from two conflicting perspectives: the importance of following the process according to the guidelines or taking a more pragmatic approach. Conclusion This study highlights the need to establish structures facilitating safe self-care among frail groups, such as older persons dependent on home care. Our findings emphasize that the demarcation between, and responsibilities of, organizations need to be discussed and clarified to offer person-centered support. Comprehensible guidelines and functioning communication channels must be established so that all important perspectives can be heard, not least the patient’s.

Complications of colonoscopy surveillance of patients with Lynch syndrome – 33 years of follow up

Background and study aims: Lynch syndrome (LS) is a hereditary autosomal dominant condition, with an increased lifetime risk of developing malignancies including colorectal cancer (CRC). Current guidelines differ in recommended colonoscopy-surveillance intervals from 1 to 2 years. Although colonoscopy is considered a safe procedure, there are risks of severe adverse events (SAEs), such as perforation and bleeding, as well as adverse events (AEs), such as abdominal discomfort and post-colonoscopy gastrointestinal infections. Colonoscopy-related bleeding and perforation rates have been reported 0.17% and 0.11%, respectively. However, there are insufficient data regarding complications of colonoscopy-surveillance for LS patients. This study aims to investigate the risk of AEs among LS patients during colonoscopy in the Stockholm region. Patients and methods: This retrospective cohort study includes 351 LS patients undergoing endoscopic surveillance at the Karolinska University Hospital, August 1989 – April 2021. Data from endoscopic surveillance colonoscopies were extracted from patients’ medical records. Results: Of 1873 endoscopies in 351 LS patients, 12 complications (AEs) were documented within 30 days (0.64%) and with a total of 3 bleedings (SAEs, 0.16%). No perforations were identified. Conclusion: Colonoscopy surveillance for LS patients shows a comparatively low risk of AEs per-examination. Colonoscopy complications per-patient, including both SAEs and AEs, show a significantly higher risk. Colonoscopy complications only including SAEs, show a comparatively low risk. Understanding the lifetime risk of surveillance-related colonoscopy complications is important when designing targeted surveillance programmes.

Attainment of remission and low disease activity after treatment with belimumab in patients with systemic lupus erythematosus: a post-hoc analysis of pooled data from five randomised clinical trials

Disease remission or low disease activity are key treatment targets for patients with systemic lupus erythematosus (SLE). Pivotal trials of belimumab were conducted before the introduction of these targets. In this study, we aimed to pool data across trials to assess attainment of remission and low disease activity in a large, racially and culturally diverse patient population with SLE. In this integrated post-hoc analysis, we pooled data from five phase 3 trials of belimumab (BLISS-76 [NCT00410384], BLISS-52 [NCT00424476], BLISS-NEA [NCT01345253], BLISS-SC [NCT01484496], and EMBRACE [NCT01632241]), in patients with active, autoantibody-positive SLE. Patients were randomly assigned to receive belimumab (10 mg/kg per month intravenously or 200 mg per week subcutaneously) or placebo, plus standard therapy. The proportion of patients with Definitions of Remission in SLE (DORIS) remission and lupus low disease activity state (LLDAS) were analysed every 4 weeks from week 4 to week 52 for belimumab versus placebo, using modified Poisson regression adjusted for trial variance, in all patients and in subgroups per baseline SLE Disease Activity Index-2000 score (<10 or ≥10); anti-double stranded DNA positivity (yes or no); low complement 3 (C3) or C4 levels (yes or no); anti-dsDNA positivity or low C3 or C4 levels (yes and no); prednisone-equivalent dose (≤7·5 mg per day or >7·5 mg per day); antimalarial use (yes or no); and by race (Black African ancestry or African American, Asian, Indigenous American, or White). Data for 3086 patients (1869 in the belimumab group and 1217 in the placebo group) were analysed. 2913 (94%) of 3086 patients were women and 173 (6%) were men, and the median age was 36 years (IQR 28-45). The proportion of patients with DORIS remission was significantly higher in the belimumab group than the placebo group at weeks 28, 48, and 52 (week 52: 148 [8%] of 1869 participants vs 68 [6%] of 1217 participants; risk ratio 1·51 [95% CI 1·15-1·99]; p=0·0055). The proportion of patients who attained LLDAS was higher in the belimumab group than the placebo group at weeks 8, 24, 32-52 (week 52: 322 [17%] of 1869 participants vs 125 [10%] of 1217 participants; 1·74 [1·44-2·12]; p<0·0001). A higher proportion of patients had DORIS remission at week 52 in the belimumab group than the placebo group among all baseline subgroups denoting high disease activity, with the exception of those on a prednisone-equivalent dose higher than 7·5 mg per day in whom there was no difference for DORIS remission with belimumab versus placebo. The proportion of patients with LLDAS was significantly higher among patients in the belimuab group than those who received placebo from week 44 in all baseline subgroups denoting high disease activity or earlier in some subgroups, and the differences were maintained at week 52. In adults with active SLE, belimumab plus standard therapy yielded greater benefit than placebo plus standard therapy in attaining DORIS remission (for which low rates were attained in both groups) and LLDAS, with differences observed as early as week 28 for DORIS remission and week 8 for LLDAS.

Hospital admissions in the last month of life for patients with advanced cancer residing in nursing homes

IntroductionOvertreatment and frequent hospital admissions in patients at end-of-life has been shown in several studies, including in the nursing home (NH) setting. However, overtreatment in NH residents with advanced cancer has not been studied before. Our objective was to compare emergency room (ER) visits and hospital admissions in the last month of life and place of death among NH residents with or without advanced cancer. Materials and MethodsThis retrospective study is based on Region Stockholm's administrative database from 2015 to 2019. Demographic data, ER visits, and Hospital Frailty Risk Score (HFRS) were extracted for each subject. Univariable and multivariable analyses were performed, and odds ratios (OR) calculated. ResultsIn total, 30,324 NH residents were identified, of which 1807 had advanced cancer. Advanced cancer was associated with more ER visits in the last month of life in the univariable analysis but not when adjusted for age, sex, and risk of frailty with an adjusted aOR of 1.07 (95 %CI 0.97–1.19). Having a cancer diagnosis was significantly associated with acute hospital admissions, although the association was rather weak with an aOR 1.13 (95 %CI 1.02–1.26). NH residents with advanced cancer were less likely to die in hospital than non-cancer residents: aOR 0.63 (95 %CI 0.54–0.73). DiscussionNH residents with advanced cancer have a slightly higher risk of hospital admissions in the last month of life compared to non-cancer residents but are less likely to die in hospital. The probability of ER visits during the last month of life was similar between NH residents with and without cancer.

Statin treatment for primary and secondary prevention in elderly patients—a cross-sectional study in Stockholm, Sweden

BackgroundAge is a major risk factor for atherosclerotic cardiovascular disease (CVD) and death, but there has been a debate about benefit-risk of statin treatment in the elderly with limited evidence on benefits for primary prevention, while there is strong evidence for its use in secondary prevention.AimThe aim of this study was to provide an overview of statin utilization in primary and secondary prevention for patients 75–84 years and ≥ 85 years in the Swedish capital Region Stockholm in 2019.MethodsThis is a cross-sectional study based on the regional healthcare database VAL containing all diagnoses and dispensed prescription drugs for all 174,950 inhabitants ≥ 75 years old in the Stockholm Region. Prevalence and incidence were analyzed by sex, age, cardiovascular risk, substance, and the intensity of treatment.ResultsA total of 35% of all individuals above the age of 75 in the region were treated with statins in 2019. The overall incidence in this age group was 31 patients per 1000 inhabitants. Men, individuals 75–84 compared to ≥ 85 years of age, and those with higher cardiovascular risk were treated to a greater extent. Simvastatin was used primarily by prevalent users and atorvastatin by incident users. The majority was treated with moderate-intensity dosages and fewer women received high intensity treatment.ConclusionsStatins are widely prescribed in the elderly. Physicians seem to consider individual cardiovascular risk when deciding to initiate statin treatment for elderly patients, but here may still be some undertreatment among high-risk patients (especially women and elderly 85 + years) and some overtreatment among patients with low-risk for CVD.

Multilingual Classroom Assistants as Nonauthorized Policy Actors: Understanding and Enacting a Swedish School Policy

ABSTRACT The aim of this article is to explore how national-level Swedish policy intentions concerning multilingual classroom assistance are being enacted at the local level. The article is based on semi-structured interviews with 12 newly arrived students and 30 interviews with teachers, multilingual classroom assistants, school leaders, and other school staff, conducted in 2018/2019 at two compulsory schools in the Stockholm region, during one year of fieldwork. The data were analysed using the conceptual bases of critical policy analysis. The findings reveal that the structural conditions for enacting national policy concerning multilingual classroom assistance are characterized by collectivizing strategies. The schools build their support measure strategies on selective appropriations of collective solutions to achieve their own organizational strategies and goals. Engagement in policy enactment by constructing local strategies is not an option for all actors in these two schools, but only for authorized policy actors. The study further demonstrates the need to reorganize multilingual classroom assistance by grounding it in students’ individual educational needs.

The impact of discharge letter content on unplanned hospital readmissions within 30 and 90 days in older adults with chronic illness – a mixed methods study

BackgroundCare transitions are high-risk processes, especially for people with complex or chronic illness. Discharge letters are an opportunity to provide written information to improve patients’ self-management after discharge. The aim of this study is to determine the impact of discharge letter content on unplanned hospital readmissions and self-rated quality of care transitions among patients 60 years of age or older with chronic illness.MethodsThe study had a convergent mixed methods design. Patients with chronic obstructive pulmonary disease or congestive heart failure were recruited from two hospitals in Region Stockholm if they were living at home and Swedish-speaking. Patients with dementia or cognitive impairment, or a “do not resuscitate” statement in their medical record were excluded. Discharge letters from 136 patients recruited to a randomised controlled trial were coded using an assessment matrix and deductive content analysis. The assessment matrix was based on a literature review performed to identify key elements in discharge letters that facilitate a safe care transition to home. The coded key elements were transformed into a quantitative variable of “SAFE-D score”. Bivariate correlations between SAFE-D score and quality of care transition as well as unplanned readmissions within 30 and 90 days were calculated. Lastly, a multivariable Cox proportional hazards model was used to investigate associations between SAFE-D score and time to readmission.ResultsAll discharge letters contained at least five of eleven key elements. In less than two per cent of the discharge letters, all eleven key elements were present. Neither SAFE-D score, nor single key elements correlated with 30-day or 90-day readmission rate. SAFE-D score was not associated with time to readmission when adjusted for a range of patient characteristics and self-rated quality of care transitions.ConclusionsWhile written summaries play a role, they may not be sufficient on their own to ensure safe care transitions and effective self-care management post-discharge.Trial registrationClinical Trials. giv, NCT02823795, 01/09/2016.

Burden of CKD-Associated Pruritus and Adverse Clinical Outcomes in Patients Receiving Dialysis: The Stockholm Creatinine Measurements (SCREAM) Project

Pruritus is a common but not well-characterized complaint of patients receiving maintenance dialysis. This study sought to quantify the burden of pruritus and its associated adverse health outcomes in this population. Observational study. All patients receiving maintenance dialysis in Stockholm, Sweden, during 2005-2021. Clinically recognized pruritus defined using International Classification of Diseases, Tenth Revision codes or a prescription for antipruritus treatments (including UV therapy). All-cause mortality, severe infection-related hospitalizations (composite of endocarditis, peritoneal dialysis-related peritonitis, hemodialysis/peritoneal dialysis-related catheter infection, sepsis due to Staphylococcus spp., or skin infection) and incident diagnoses of anxiety/depression and sleep disorders. Multivariable logistic regression and cause-specific hazards models to analyze factors associated with prevalent and new-onset pruritus, respectively. Multivariable cause-specific hazards models with time-varying exposure were used to explore the association of prevalent and new-onset pruritus with adverse health outcomes. Among 3,281 dialysis recipients (median age, 64 years; 66% men; 69% receiving hemodialysis, 77% with incident dialysis), 456 (14%) had pruritus at enrollment. During a median follow-up of 3.3 (IQR, 1.3-9.2) years, 539 (19%) additional patients experienced pruritus. Older age, female sex, a lower serum albumin level, and higher C-reactive protein, serum calcium, and phosphorus levels were independently associated with pruritus. Compared with patients without pruritus, patients with pruritus were at a higher risk of sleep disorders (adjusted HR, 1.96; 95% CI, 1.60-2.39), developing anxiety/depression (adjusted HR, 1.56; 95% CI, 1.23-1.98), and being hospitalized for severe infections (adjusted HR, 1.36; 95% CI, 1.18-1.57), the latter attributed to higher risk of sepsis and peritoneal dialysis-related peritonitis. There was no detectable association between the development of pruritus and all-cause mortality. Potential misclassification bias if pruritus is not clinically recognized, lack of information on pruritus intensity/severity, use of diagnostic codes for exposure and outcome diagnoses. At least one third of patients experience pruritus during their first years undergoing dialysis, and pruritus was consistently associated with adverse health outcomes. Pruritus is a common but not well-characterized symptom of patients receiving dialysis. We analyzed data from 3,281 patients receiving maintenance hemodialysis or peritoneal dialysis in the region of Stockholm, Sweden. At baseline, 14% of patients had pruritus, and pruritus developed in an additional 19% of patients during their time receiving dialysis. We identified conditions associated with the development of pruritus (eg, older age, female sex, lower serum albumin level, and higher C-reactive protein, serum calcium, and phosphorus levels) and observed that the presence of pruritus was associated with higher risks of sleep disorders, developing anxiety and depression, and being hospitalized for severe infections. No association between pruritus and all-cause mortality was identified.
