Hospital Readmissions by Variation in Engagement in the Health Care Hotspotting Trial: A Secondary Analysis of a Randomized Clinical Trial

JAMA Netw Open. 2023 Sep 5;6(9):e2332715. doi: 10.1001/jamanetworkopen.2023.32715.

ABSTRACT

IMPORTANCE: Variability in intervention participation within care management programs can complicate standard analysis strategies.

OBJECTIVE: To evaluate whether care management was associated with reduced hospital readmissions among individuals with higher participation probabilities.

DESIGN, SETTING, AND PARTICIPANTS: A total of 800 hospitalized patients aged 18 years and older were randomized as part of the Health Care Hotspotting randomized clinical trial, which was conducted in Camden, New Jersey, from June 2014 to September 2017. Data were collected through October 2018. In this new analysis performed between April 6, 2022, and April 23, 2023, the distillation method was applied to account for variable intervention participation. A gradient-boosting machine learning model produced predicted probabilities of engaged participation using baseline covariates only. Predicted probabilities were used to trim both intervention and control populations in an equivalent manner, and intervention effects were reevaluated within study population subsets that were increasingly concentrated with patients having higher participation probabilities. Patients had 2 or more hospitalizations in the 6-month preenrollment period and documented evidence of chronic illness and social complexity.

INTERVENTION: Multidisciplinary teams provided services to patients in the intervention arm for a mean 120 days after hospital discharge. Patients in the control group received usual postdischarge care.

MAIN OUTCOMES AND MEASURES: Hospital readmission rates and counts 30, 90, and 180 days postdischarge.

RESULTS: Of 800 eligible patients, 782 had complete discharge information and were included in this analysis (mean [SD] age, 56.6 [12.7] years; 395 [50.5%] female). In the intent-to-treat analysis, the unadjusted 180-day readmission rate for treatment and control groups was 60.1% vs 61.7% (adjusted odds ratio, 0.95; 95% CI, 0.71-1.28; P = .73) and the mean (SD) number of 180-day readmissions was 1.45 (1.89) vs 1.48 (1.94) (adjusted incidence rate ratio, 0.99, 95% CI, 0.88-1.12; P = .86). Among the population with the highest participation probabilities, the mean (SD) 180-day readmission count was 1.22 (1.74) vs 1.57 (1.74) and the incidence rate ratio attained statistical significance (adjusted incidence rate ratio, 0.74; 95% CI, 0.56-0.99; P = .045). Adjusted odds ratios and adjusted incidence rate ratios for 30- and 90-day outcomes reached statistical significance after population distillation.

CONCLUSIONS AND RELEVANCE: This secondary analysis of a randomized clinical trial found that care management was associated with reduced readmissions among patients with higher participation probabilities, suggesting that program operation could be improved by addressing barriers to participation and refining inclusion criteria to identify patients most likely to benefit.

Phosphatidylethanol vs Transdermal Alcohol Monitoring for Detecting Alcohol Consumption Among Adults

JAMA Netw Open. 2023 Sep 5;6(9):e2333182. doi: 10.1001/jamanetworkopen.2023.33182.

ABSTRACT

IMPORTANCE: Alcohol biomarkers can improve detection of heavy alcohol use in clinical care, yet cutoffs for phosphatidylethanol (PEth), a blood biomarker, have not been established.

OBJECTIVE: To determine the optimal cutoff for PEth for heavy alcohol consumption in a study of middle-age and older adults.

DESIGN, SETTING, AND PARTICIPANTS: This was a 4-week diagnostic study of adults with paroxysmal atrial fibrillation (AF) and current alcohol consumption, recruited from general cardiology and cardiac electrophysiology outpatient clinics from September 2014 to September 2019. Data were analyzed from October 2021 to March 2022.

MAIN OUTCOMES AND MEASURES: The main aim was to determine the optimal PEth cutoff for heavy alcohol consumption, using the Secure Continuous Remote Alcohol Monitor (SCRAM) to measure transdermal alcohol. Area under the curve (AUC) for PEth-detected compared with SCRAM-detected heavy alcohol consumption in any week over the prior 4 weeks (ie, ≥3 [women] and ≥4 [men] episodes) or any estimated breath alcohol of 0.08% or greater in any week, and the PEth cutoff was calculated using the Youden J statistic. Similar analyses were conducted comparing PEth with individual drinks reported by pressing an event monitor, retrospective self-report via the Alcohol Use Disorders Identification Test-Consumption (AUDIT-C), and using 2-week look-backs.

RESULTS: In this diagnostic study of 64 patients with both PEth and SCRAM measures over 4 weeks (54 [84.4%] men; mean age, 65.5 [95% CI, 62.6-68.5] years; 51 [79.7%] White), 31 (48.4%) had any SCRAM-detected heavy alcohol consumption over the 4 weeks, and the median (IQR) PEth at 4 weeks was 23 ng/mL (<limit of quantification to 60 ng/mL). The AUC for PEth vs any SCRAM-detected heavy alcohol consumption was 0.83 (95% CI, 0.72-0.93). The optimal PEth cutoff was 18.5 ng/mL (AUC, 0.83; 95% CI, 0.72-0.93), with sensitivity of 83.9% (95% CI, 66.3%-94.5%) and specificity of 72.7% (95% CI, 54.5%-86.7%). The PEth test characteristics by individual drink reporting using the event monitors and by the AUDIT-C, and by these measures and by SCRAM collected for 2-week intervals, were similar to those compared with the 4-week SCRAM.

CONCLUSIONS AND RELEVANCE: In a predominately middle-age and older White male population, PEth compared well with SCRAM. A PEth cutoff of 18.5 ng/mL (or rounded to 20 ng/mL, a recommended PEth cutoff for significant alcohol consumption) can be used in clinical care to detect heavy alcohol consumption in middle-age and older men.

Blood Levels of Organochlorine Contaminants Mixtures and Cardiovascular Disease

JAMA Netw Open. 2023 Sep 5;6(9):e2333347. doi: 10.1001/jamanetworkopen.2023.33347.

ABSTRACT

IMPORTANCE: Cardiovascular toxic effects derived from high exposures to individual organochlorine compounds are well documented. However, there is no evidence on low but continuous exposure to combined organochlorine compounds in the general population.

OBJECTIVE: To evaluate the association of combined exposure to several organochlorine compounds, including organochlorine pesticides and polychlorinated biphenyls, with incident cardiovascular disease (CVD) in the general population.

DESIGN, SETTING, AND PARTICIPANTS: This prospective nested case-control study included data from 2 cohorts: the Swedish Mammography Cohort-Clinical (SMC-C) and the Cohort of 60-Year-Olds (60YO), with matched case-control pairs based on age, sex, and sample date. Baseline blood sampling occurred from November 2003 to September 2009 (SMC-C) and from August 1997 to March 1999 (60YO), with follow-up through December 2017 (SMC-C) and December 2014 (60YO). Participants with myocardial infarction or ischemic stroke were matched with controls for composite CVD evaluation. Data were analyzed from September 2020 to May 2023.

EXPOSURES: A total of 25 organochlorine compounds were measured in blood at baseline by gas chromatography-triple quadrupole mass spectrometry. For 7 compounds, more than 75% of the samples were lower than the limit of detection and not included.

MAIN OUTCOMES AND MEASURES: Incident cases of primary myocardial infarction and ischemic stroke were ascertained via linkage to the National Patient Register (International Statistical Classification of Diseases and Related Health Problems, Tenth Revision codes I21 and I63). The quantile-based g-computation method was used to estimate the association between the combined exposure to several organochlorine compounds and composite CVD.

RESULTS: Of 1528 included participants, 1024 (67.0%) were female, and the mean (SD) age was 72 (7.0) years in the SMC-C and 61 (0.1) years in the 60YO. The odds ratio of composite CVD was 1.71 (95% CI, 1.11-2.64) per 1-quartile increment of total organochlorine compounds mixture. Organochlorinated pesticides were the largest contributors, and β-hexachlorocyclohexane and transnonachlor had the highest impact. Most of the outcome was not explained by disturbances in the main cardiometabolic risk factors, ie, high body mass index, hypertension, lipid alteration, or diabetes.

CONCLUSIONS AND RELEVANCE: In this prospective nested case-control study, participants with higher exposures to organochlorines had an increased probability of experiencing a cardiovascular event, the major cause of death worldwide. Measures may be required to reduce these exposures.

Application of overlap anastomosis in digestive tract reconstruction during minimally invasive Ivor-Lewis esophagectomy

Updates Surg. 2023 Sep 12. doi: 10.1007/s13304-023-01642-0. Online ahead of print.

ABSTRACT

This study aims to assess the feasibility of the Overlap anastomosis technique in minimally invasive Ivor-Lewis esophagectomy. An accompanying video presentation elucidates our surgical procedures. A retrospective review of 46 patients diagnosed with middle and lower esophageal cancer was conducted. These patients underwent minimally invasive Ivor-Lewis esophagectomy with Overlap anastomosis between January 2019 and December 2020. A consistent team of surgeons performed all procedures. The initial phase involved laparoscopic stomach mobilization, intra-abdominal lymphadenectomies, and preparation of the tubular stomach. Subsequently, with the patient in the left decubitus position, thoracoscopy was used to dissect the esophagus, excise the diseased segment, and conduct mediastinal lymph node dissection. The final stage encompassed the intrathoracic gastroesophageal anastomosis using the Overlap method. All surgeries were completed without converting to an open approach, achieving complete resection. There were no operative fatalities, with an average surgery duration of 259.4 min. Average statistics included intraoperative blood loss of 92.3 ml, 16.2 lymph nodes dissected, and a postoperative hospital stay of 10.3 days. Postoperative complications comprised three instances of hoarseness due to recurrent laryngeal nerve palsy, two cases of aspiration pneumonia, one occurrence of chylothorax, and one gastric emptying disorder. Anastomotic technique-related complications were minimal, with only one patient experiencing an anastomotic leak that resolved spontaneously and two patients facing anastomotic stenosis, which was subsequently alleviated. Our findings posit that the Overlap anastomosis method is safe and efficient for minimally invasive Ivor-Lewis esophagectomy, marked by a notably low rate of anastomosis-related complications. Further evaluation of its long-term implications remains necessary.

Knowledge, attitudes and practices of Irish doctors regarding stop smoking care and electronic cigarettes

Ir J Med Sci. 2023 Sep 12. doi: 10.1007/s11845-023-03507-2. Online ahead of print.

ABSTRACT

BACKGROUND: Smoking continues to cause harm on a huge scale in Ireland. Doctors can help this harm through providing safe, effective and clinically sound stop smoking care, but the needs of Irish doctors in this area are largely uncharted.

AIMS: We assessed the knowledge, attitudes and practices of Irish doctors regarding stop smoking care and electronic cigarettes.

METHODS: An Internet-based cross-sectional survey was administered to members of the Royal College of Physicians in Ireland and the Irish College of General Practitioners. Descriptive statistics for key parameters were derived and factors associated with more consistent practice of brief intervention, a key component of stop smoking care, were analysed using chi-square testing.

RESULTS: There were 250 responses (58.7% female, 53.0% aged under 45 years, 55.1% graduated in medicine before 2000 and 57.2% worked in general practice). Most (84.9%) reported often or always asking about patient’s smoking behaviour, and most (86.1%) reported often or always advising patients to stop. However, providing or arranging effective stop smoking care was weak and less consistently practised, and while most (91.4%) saw it as a responsibility, few doctors (28.5%) agreed they were sufficiently trained in this area of clinical care. Confidence in the knowledge of e-cigarettes was poor.

CONCLUSIONS: While there is a strong reservoir support and areas of good reported practice in stop smoking care among doctors in Ireland, the development of their knowledge and skills in arranging effective care should be supported if doctors are to fulfil their huge potential role in tackling the harm caused by smoking.

ITI consensus report on zygomatic implants: indications, evaluation of surgical techniques and long-term treatment outcomes

Int J Implant Dent. 2023 Sep 12;9(1):28. doi: 10.1186/s40729-023-00489-9.

ABSTRACT

OBJECTIVES: The aim of the ITI Consensus Workshop on zygomatic implants was to provide Consensus Statements and Clinical Recommendations for the use of zygomatic implants.

MATERIALS AND METHODS: Three systematic reviews and one narrative review were written to address focused questions on (1) the indications for the use of zygomatic implants; (2) the survival rates and complications associated with surgery in zygomatic implant placement; (3) long-term survival rates of zygomatic implants and (4) the biomechanical principles involved when zygoma implants are placed under functional loads. Based on the reviews, three working groups then developed Consensus Statements and Clinical Recommendations. These were discussed in a plenary and finalized in Delphi rounds.

RESULTS: A total of 21 Consensus Statements were developed from the systematic reviews. Additionally, the group developed 17 Clinical Recommendations based on the Consensus Statements and the combined expertise of the participants.

CONCLUSIONS: Zygomatic implants are mainly indicated in cases with maxillary bone atrophy or deficiency. Long-term mean zygomatic implant survival was 96.2% [95% CI 93.8; 97.7] over a mean follow-up of 75.4 months (6.3 years) with a follow-up range of 36-141.6 months (3-11.8 years). Immediate loading showed a statistically significant increase in survival over delayed loading. Sinusitis presented with a total prevalence of 14.2% [95% CI 8.8; 22.0] over a mean 65.4 months follow-up, representing the most common complication which may lead to zygomatic implant loss. The international experts suggested clinical recommendations regarding planning, surgery, restoration, outcomes, and the patient’s perspective.

Efficiency and safety of optic canal unroofing in tuberculum sellae meningiomas: a meta-analysis and systematic review

Neurosurg Rev. 2023 Sep 12;46(1):240. doi: 10.1007/s10143-023-02151-9.

ABSTRACT

Optic canal unroofing (OCU) has gradually become a routine technique for tuberculum sellae meningiomas (TSMs) resection. This meta-analysis aimed to evaluate the efficacy and safety of OCU. A systematic review and meta-analysis of the published literature on this topic from 2003 to 2023 were conducted in accordance with the PRISMA guidelines. Rigorous statistical analysis with a p-value was performed for related change in visual improvement, gross total resection (GTR), visual deterioration, and olfactory nerve damage. The study included 15 articles with 384 patients in whom OCU was performed by the transcranial approach (TCA) or the endoscopic endonasal approach (EEA). Of these, 341 patients had preoperative visual loss, and 266 patients had postoperative visual recovery. The overall rate of visual improvement was 0.803 (95% CI: 0.733-0.874, p < 0.01). The rate of visual improvement in the EEA and TCA groups was 0.884 (95% CI: 0.803-0.965, p < 0.01) and 0.788 (95% CI: 0.700-0.875, p < 0.01). Further analysis of classification shows that the rate of visual improvement in Type I: < 2 cm was 0.889(95% CI: 0.739-0.969), Type II:2-4 cm was 0.844(95% CI: 0.755-0.910), Type III: > 4 cm was 0.500(95% CI: 0.068-0.932) and the total was 0.853(95% CI: 0.779-0.927 p < 0.01) with low heterogeneity of I2 = 20.80%.Twelve studies separately reported GTR with OCU was 293; the rate of GTR was 0.911 (95% CI: 0.848-0.961, p < 0.01). And the rate of GTR in Type I: < 2 cm was 0.933(95% CI: 0.817-0.986), Type II:2-4 cm was 0.880(95% CI: 0.800-0.936), Type III: > 4 cm was 0.600(95% CI: 0.147-0.947). The total was 0.897(95% CI: 0.830-0.965 p < 0.01) with low heterogeneity of I2 = 34.57%. The related complications of OCU were visual deterioration and olfactory nerve damage. Visual decline was reported in nine studies, and the rate was 0.077 (95% CI: 0.041-0.113, p < 0.01). Six studies reported olfactory nerve damage, and the overall rate was 0.054 (95% CI: 0.019-0.090, p < 0.01). OCU could significantly recover preoperative impaired vision and make GTR easier to achieve, which was also a safe and effective technique in TSM.

Identifying possible biomarkers of lower urinary tract symptoms using metabolomics and partial least square regression

Metabolomics. 2023 Sep 12;19(9):82. doi: 10.1007/s11306-023-02046-2.

ABSTRACT

INTRODUCTION: The objective of this study was to explore potential novel biomarkers for moderate to severe lower urinary tract symptoms (LUTS) using a metabolomics-based approach, and statistical methods with significant different features than previous reported.

MATERIALS AND METHODS: The patients and the controls were selected to participate in the study according to inclusion/exclusion criteria (n = 82). We recorded the following variables: International prostatic symptom score (IPSS), prostate volume, comorbidities, PSA, height, weight, triglycerides, glycemia, HDL cholesterol, and blood pressure. The study of 41 plasma metabolites was done using the nuclear magnetic resonance spectroscopy technique. First, the correlations between the metabolites and the IPSS were done using Pearson. Second, significant biomarkers of LUTS from metabolites were further analysed using a multiple linear regression model. Finally, we validated the findings using partial least square regression (PLS).

RESULTS: Small to moderate correlations were found between IPSS and methionine (-0.301), threonine (-0.320), lactic acid (0.294), pyruvic acid (0.207) and 2-aminobutyric-acid (0.229). The multiple linear regression model revealed that only threonine (p = 0.022) was significantly associated with IPSS, whereas methionine (p = 0.103), lactic acid (p = 0.093), pyruvic acid (p = 0.847) and 2-aminobutyric-acid (p = 0.244) lost their significance. However, all metabolites lost their significance in the PLS model.

CONCLUSION: When using the robust PLS-regression method, none of the metabolites in our analysis had a significant association with lower urinary tract symptoms. This highlights the importance of using appropriate statistical methods when exploring new biomarkers in urology.

Facilitators and barriers to COVID-19 vaccination among incarcerated people and staff in three large, state prisons: a cross-sectional study

Health Justice. 2023 Sep 12;11(1):38. doi: 10.1186/s40352-023-00240-x.

ABSTRACT

BACKGROUND: The COVID-19 pandemic has disproportionately impacted individuals in carceral facilities – both incarcerated people and staff. Vaccination is an important tool in reducing the risk of COVID-19 infection, hospitalization, and death. While the importance of promoting vaccination is clear, there are considerable barriers to doing so. This study aims to better understand: (1) why individuals chose to receive the COVID-19 vaccine; (2) why individuals were hesitant to vaccinate; (3) what motivators might influence a person’s decision to get vaccinated; and (4) what sources of information about COVID-19 vaccination people trust.

METHODS: We conducted a survey of incarcerated people and facility staff in three, large state prisons in Minnesota to identify barriers and facilitators to COVID-19 vaccination. Facilities were recruited to participate through purposive sampling, and surveys were administered between November and December 2021. Descriptive statistics were calculated using Stata.

RESULTS: Findings demonstrate that, for incarcerated individuals (N = 1,392), the most common reason for getting vaccinated was to return to normal activities in prison (61%, n = 801); the most common reason for being hesitant to get vaccinated was “other” (41%, n = 342), with individuals citing a variety of concerns. For staff (N = 190), the most common reason for getting vaccinated was to protect the health of family and friends (79%, n = 114); the most common reasons for being hesitant were disbelief that vaccination is necessary (55%, n = 23) and distrust of healthcare and public health systems (55%, n = 23). Incarcerated individuals reported that monetary and programmatic incentives would help motivate them to get vaccinated, while staff members said speaking with healthcare professionals and monetary incentives would help motivate them. Lastly, trusted sources of information for incarcerated individuals were healthcare professionals outside of prisons and jails, along with friends and family members. Staff members reported that they trusted healthcare professionals and national health organizations for information about COVID-19 vaccination.

CONCLUSIONS: While considerable barriers to COVID-19 vaccination persist among both incarcerated individuals and staff members, these findings also highlight areas of intervention to increase COVID-19 vaccine confidence and promote health equity among those disproportionately impacted by the COVID-19 pandemic.

Clinical outcomes in elderly patients with infections caused by NDM-producing Klebsiella pneumoniae: results from a real-life retrospective single center study in an endemic area

Intern Emerg Med. 2023 Sep 12. doi: 10.1007/s11739-023-03416-3. Online ahead of print.

ABSTRACT

Real-life outcomes data for elderly patients with infections caused by Klebsiella pneumoniae producing New Delhi metallo-beta-lactamase (NDM-Kp) are lacking. We conducted a retrospective cohort study enrolling 33 consecutive adult patients (mean age 77.4 years; 48.5% males; mean Charlson Comorbidity Index-CCI 5.9) hospitalized for NDM-Kp infections during a 24-month period in an Italian highly endemic area. 78.8% were admitted to Internal Medicine ward. 45.4% of patients had bloodstream infections (BSI), 39.4% urinary tract infections (UTI) without BSI, 9.1% respiratory tract infections and 6.1% intra-abdominal infections. 93.9% had rectal colonization.Adequate definitive antibiotic therapy (mainly represented by aztreonam plus ceftazidime/avibactam) was provided to 36.4% of cases. Mean age and CCI of patients adequately treated were significantly lower than those inadequately treated (71.2 vs 80.9 years, p = 0.041, and 4.6 vs 6.7, p = 0.040, respectively). Patients adequately treated had a mean hospitalization length significantly higher (28 vs 15 days, p = 0.016). The overall 30-day survival rate of patients adequately and inadequately treated was 83.3% and 57.1%, respectively: this difference was not statistically significant. Mean age and CCI of 22 patients who survived at 30 days were lower than those of 11 patients who died (73.7 vs 84.8 years, p = 0.003, and 5.3 vs 7.2, p = 0.049, respectively). Twelve survivors received an inadequate therapy: 8/12 had UTI. Six of nine patients inadequately treated who died within 30 days, died before microbiological diagnosis. Our study provides real-life data on outcomes of elderly and multimorbid patients hospitalized for infections caused by NDM-Kp. Further studies with larger sample size are warranted.
