ABSTRACT

BACKGROUND: Incorrect surgical counts are closely related to retained surgical items, which pose a threat to patients. However, the risk factors for incorrect surgical counts have not been identified yet.

AIM: To identify the risk factors associated with incorrect surgical counts during surgery in a tertiary hospital.

DESIGN: An observational case-control study.

METHODS: Seventy cases of incorrect surgical counts were reviewed in this study. Data were collected from January 1, 2014, to April 4, 2019. For each case, we included four randomly selected control cases involving the same surgical procedures by the same surgeon within a 6-month period for comparison. The medical data of these cases were extracted for further statistical analysis.

RESULTS: A higher incidence of incorrect surgical counts was observed among surgical counts performed between 8:00 a.m. to 12:00 a.m., emergency operations, prolonged procedures, and/or after addition of surgical items.

CONCLUSION: Prolonged surgical procedures, emergency operations, time of occurrence, and addition of surgical items were the risk factors related to incorrect surgical counts during surgery.

SUMMARY STATEMENT: What is already known about the topic? Incorrect surgical count is a perplexing problem during operation. Incorrect surgical count is closely associated with retained surgical items which can cause patient injury. The underlaying risk factors of incorrect surgical count were still unknown. What this paper adds? This was the first case-control study for incorrect surgical counts in China. The present research demonstrated that several risk factors were significantly associated with the occurrence of incorrect surgical counts, including the time period, the type of surgery, and the duration of the procedure. Vigilance should be maintained during an emergency operation or a long procedure to reduce the incidence of incorrect surgical counts. The implications of this paper: It is important for nurses to be aware of the factors that can interfere with correct surgical counts, thereby ensuring vigilance during emergency operations or long procedures. By identifying these risk factors, a more comprehensive safety policy in the operation room can be implemented to reduce incorrect surgical counts. Novel technological adjuncts should be promoted in the operating room gradually to improve overall patient safety.

ABSTRACT

INTRODUCTION: We have read with great interest the meta-analysis that examined the impact of increased red cell distribution width (RDW) and COVID-19 outcomes, conducted by Lee and colleagues, and recently published in the Journal of Medical Virology. The authors concluded that elevations in RDW were associated with adverse COVID-19 outcomes. However, the impact of elevation of RDW independent of anemia in COVID-19 remains to be clarified.

METHODS: Patients ≥18 years who were diagnosed with COVID-19 at the Mount Sinai Health System between March 1 and April 1, 2020 and had a complete blood count (CBC) at presentation (n=2562) were selected to assess the association between RDW and mortality. Multivariable Cox proportional hazards regression models, stratified by presence of anemia, were performed to assess the independent association of RDW with mechanical ventilation and mortality.

RESULTS: At univariate analysis, elevated RDW was statistically significantly associated with mechanical ventilation (p = 0.0109) and mortality (p < 0.0001). We found that elevated RDW was statistically associated with higher risk of both being placed on a ventilator (HRadj: 1.66, 95% CI: 1.19-2.32) and mortality (HRadj: 1.60, 95% CI: 1.18-2.15) in non-anemic patients, but there was no association in anemic patients. These associations were independent of the effects of age, sex, race, and CCI.

DISCUSSION: In this study, we show that the elevated RDW association with mortality and mechanical ventilation is present exclusively in non-anemic patients. Therefore, we propose that RDW be considered by clinicians, especially in non-anemic patients, when risk-stratifying COVID-19 patients. This article is protected by copyright. All rights reserved.

ABSTRACT

BACKGROUND: Older patients with acute decompensated heart failure (ADHF) have severely impaired physical function (PF) and quality of life (QOL). However, relationships between impairments in PF and QOL are unknown but are relevant to clinical practice and trial design.

METHODS: We assessed 202 consecutive patients hospitalized with ADHF in the multicenter Rehabilitation Therapy in Older Acute HF Patients (REHAB-HF) Trial. PF measures included Short Physical Performance Battery (SPPB) and 6-min walk distance (6MWD). Disease-specific QOL was assessed by the Kansas City Cardiomyopathy Questionnaire (KCCQ). General QOL was assessed by the Short Form-12 (SF-12) and EuroQol-5D-5L. PF was evaluated as a predictor of QOL using stepwise regression adjusted for age, sex, race, and New York Heart Association class.

RESULTS: Participants were 72 ± 8 years, 54% women, 55% minority race, 52% with reduced ejection fraction, and body mass index 33 ± 9 kg/m² . Participants had severe impairments in PF (6MWD 185 ± 99 m, SPPB 6.0 ± 2.5 units) and disease-specific QOL (KCCQ Overall Score 41 ± 21 and Physical Score 47 ± 24) and general QOL (SF-12 Physical Score 28 ± 9 and EuroQol Visual Analog Scale 57 ± 23). There were modest, statistically significant correlations between 6MWD and KCCQ Overall, KCCQ Physical Limitation, and SF-12 Physical Scores (r = 0.23, p < 0.001; r = 0.30, p < 0.001; and r = 0.24, p = 0.001, respectively); and between SPPB and KCCQ Physical and SF-12 Physical Scores (r = 0.20, p = 0.004, and r = 0.19, p = 0.007, respectively). Both 6MWD and SPPB were correlated with multiple components of the EuroQol-5D-5L. 6MWD was a significant, weak predictor of KCCQ Overall Score and SF-12 Physical Score (estimate = 0.05 ± 0.01, p < 0.001 and estimate = 0.05 ± 0.02, p = 0.012, respectively). SPPB was a significant, weak predictor of KCCQ Physical Score and SF-12 Physical Score (estimate = 1.37 ± 0.66, p = 0.040 and estimate = 0.54 ± 0.25, p = 0.030, respectively).

CONCLUSION: In older, hospitalized ADHF patients, PF and QOL are both severely impaired but are only modestly related, suggesting that PF and QOL provide complementary information and assessment of both should be considered to fully assess clinically meaningful patient-oriented outcomes.

ABSTRACT

BACKGROUND: The recommended rocuronium dose for rapid sequence intubation is 1.0 mg/kg; however, the optimal dose for emergency airway management is not clear. We assessed the relationship between rocuronium dose and first-attempt success among emergency department (ED) patients undergoing rapid sequence intubation.

METHODS: This is a secondary analysis of the National Emergency Airway Registry (NEAR), an observational 25-center registry of ED intubations. Ninety percent recording compliance was required from each site for data inclusion. We included all patients > 14 years of age who received rocuronium for rapid sequence intubation from 1 Jan 2016 to 31 Dec 2018. We compared first-attempt success between encounters using alternative rocuronium doses (< 1.0, 1.0-1.1, 1.2-1.3 and ≥1.4 mg/kg). We performed logistic regressions to control for predictors of difficult airways, indication, pre-intubation hemodynamics, operator, body habitus and device. We also performed subgroup analyses stratified by device (direct vs. video laryngoscopy). We calculated univariate descriptive statistics and odds ratios (OR) from multivariable logistic regressions with cluster-adjusted 95% confidence intervals (CI).

RESULTS: 19,071 encounters were recorded during the 3-year period. Of these, 8,034 utilized rocuronium for rapid sequence intubation. Overall, first attempt success was 88.4% for < 1.0 mg/kg, 88.1% for 1.0-1.1 mg/kg, 89.7% for 1.2-1.3 mg/kg, and 92.2% for ≥1.4 mg/kg. Logistic regression demonstrated that when direct laryngoscopy was used and when compared to the standard dosing range of 1.0-1.1 mg/kg, the adjusted odds of a first attempt success was significantly higher in ≥1.4 mg/kg group at 1.9 (95% CI 1.3-2.7) relative to the other dosing ranges, OR 0.9 (95% CI 0.7-1.2) for < 1.0 mg/kg and OR 1.2 (95% CI 0.9-1.7) for the 1.2-1.3 mg/kg group. First-attempt success was similar across all rocuronium doses among patients utilizing video laryngoscopy. Patients who were hypotensive (SBP < 100 mmHg) prior to intubation had higher first-attempt success 94.9% versus 88.6% when higher doses of rocuronium were used. The rates of all peri-intubation adverse events and desaturation were similar between dosing groups, laryngoscope type utilized and varying pre-intubation hemodynamics.

CONCLUSIONS: Rocuronium dosed ≥1.4 mg/kg was associated with higher first attempt success when using direct laryngoscopy and among patients with pre-intubation hypotension with no increase in adverse events. We recommend further prospective evaluation of the dosing of rocuronium prior to offering definitive clinical guidance.

ABSTRACT

This study evaluated the quality of groundwater and its suitability for drinking and irrigation in the hilly area of the Taihang Mountains in Henan Province, China. Groundwater samples were collected from 43 unconfined and 20 confined wells and analyzed. The pollution index of groundwater (PIG) was estimated based on the physicochemical parameters, and seven indices, including the sodium adsorption ratio (SAR), sodium percentage (%Na), residual sodium carbonate (RSC), permeability index (PI), magnesium ratio (MR), Kelley’s ratio (KR), and corrosivity ratio (CR), were calculated to qualify the groundwater within the research area for irrigation activities. Multivariate statistical techniques were performed to better understand the hydrochemical processes. Chemical analysis showed that the dominant cation and anion were Ca²⁺ and HCO₃^–, respectively, and the principal hydrochemical facies was Ca-Mg-HCO₃. In terms of pH, total dissolved solids, Na⁺, Cl^–, F^–, and SO₄^2-, most samples were well within the limits prescribed by Chinese standards for drinking water quality, but more than half of the unconfined samples exceeded the specified limits for total hardness and nitrate. The PIG values suggested the pollution level was insignificant for all confined water samples and 72.09% of unconfined water samples, but the PIG distribution map showed that the water in the south central part of the study area had low to moderate pollution. According to the computed values of SAR, %Na, RSC, PI, KR, and MR and the results of a salinity diagram, the results further indicated that most of the studied samples were appropriate for irrigation usage. Only the CR values rendered 41.86% of the unconfined samples and 20% of the confined samples unfit for irrigation. Hence, proper measures are needed to resolve the corrosivity problem. Factor analysis resulted in the extraction of 3 factors that explained 81% of the data variability, and the extracted factors pointed towards geogenic factors governing the groundwater quality.

ABSTRACT

INTRODUCTION: Genetic variations of enzymes that affect the pharmacokinetics and hence effects of medications differ between ethnicities, resulting in variation in the risk of adverse drug reactions (ADR) between different populations. Previous work has demonstrated that risk-group considerations can be incorporated into approaches of statistical signal detection. It is unknown whether databases of individual case safety reports (ICSRs) are sensitive to pharmacogenomic differences between populations.

OBJECTIVE: The aim of this study was to explore the sensitivity of a global database of ICSRs to known pharmacogenomic risk variants common in Japan.

METHODS: The data source was VigiBase, the global database of ICSRs, including all reports entered in the version frozen on 5 January 2020. Subgroup disproportionality analysis was used to compare ICSRs of two subgroups, Japan and rest of world (RoW). Reports for UGT1A1-metabolized irinotecan and the CYP2C19-metabolized drugs voriconazole, escitalopram and clopidogrel were selected for comparison between the subgroups based upon known genetic polymorphisms with high prevalence in Japan. Contrast between the subgroups was quantified by IC delta [Formula: see text]), a robust shrinkage observed-to-expected (OE) ratio on a log scale. Harmonic mean p values (HMP) were calculated for each drug to evaluate whether a list of pre-specified ADRs were collectively significantly over- (or under-)reported as hypothesized. Daily drug dosages were calculated for ICSRs with sufficient information, and dose distributions were compared between Japan and RoW and related to differences in regionally approved doses.

RESULTS: The predictions of over-reporting patterns for specific ADRs were observed and confirmed in bootstrap HMP analyses (p = 0.004 for irinotecan and p < 0.001 for each of voriconazole, escitalopram and clopidogrel) and compared with similar drugs with different metabolic pathways. The impact of proactive regulatory action, such as recommended dosing and therapeutic drug monitoring (TDM), was also observable within the global database. For irinotecan and escitalopram, there was evidence of use of lower dosages as recommended in the Japanese labels; for voriconazole, there was evidence of use of TDM with an over-reporting of terms related to drug level measurements and an under-reporting of liver toxicity.

CONCLUSIONS: Pharmaco-ethnic vulnerabilities caused by pharmacogenomic differences between populations may contribute to differences in ADR reporting between countries in a global database of ICSRs. Regional analyses within a global database can inform on the effectiveness of local risk minimization measures and should be leveraged to catalyse the conversion of real-world usage into safer use of drugs in ethnically tailored ways.

ABSTRACT

INTRODUCTION: Outbreak of corona virus disease in 2019 (COVID-19) has resulted in significant morbidity and mortality worldwide. Our aim is to document hematological parameters of patients with COVID-19 during initial stage of diagnosis and to identify early hematological indicators of severe infection.

MATERIALS AND METHODS: This retrospective study was conducted at Shifa International Hospital, Pakistan from April to November 2020. Patients hospitalized with COVID-19, diagnosed on RT-PCR and had a complete blood count (CBC) done within 48 hours of diagnosis were included. Data was analyzed using IBM^® SPSS Statistics.

RESULTS: A total of 425 patients were included in this study out of whom 272(64%) were males. The mean age was 55.61 ± 17.84 years. 95 patients (22.4%) had normal blood counts within 48 hours of COVID-19 diagnosis. Cytopenias were seen in 193(45.4%) patients. There were 75(17.6%) mortalities during the study period. Chi-square test showed that thrombocytopenia, lymphopenia and neutrophilic leucocytosis were significantly associated with mortality (P = .037, P < .001, P < .001 respectively) and need for ventilator (P = .009, P < .001, P < .001, respectively). Neutrophilia was also associated with development of Acute Respiratory Distress Syndrome (P < .001). On ROC analysis, Neutrophil-to-Lymphocyte Ratio yielded an area under the curve (AUC) of 0.693 and 0.660 for the outcomes mortality and need for ventilator, respectively. For a subset of 288 patients who had D-dimer levels checked within 48 hours of COVID-19 diagnosis, the AUC for mortality and ventilator need was 0.708 and 0.671, respectively.

CONCLUSION: Hematological indices are vital indicators in the prognosis and risk stratification of COVID-19 during initial stages of disease.

ABSTRACT

OBJECTIVE: To evaluate the discrepancy between historical and more recent descriptions of the first stage of labour by testing whether the statistical techniques used recently (repeated measures polynomial and interval censored regression) were appropriate for detection of periods of rapid acceleration of cervical dilatation as might occur at the time of transition from a latent to an active phase of labour.

DESIGN AND SETTING: A simulation study using regression techniques.

SAMPLE: We created a simulated dataset for 500,000 labours with clearly defined latent and active phases using the parameters described by Friedman. Additionally, we created a dataset comprising 500,000 labours with a progressively increasing rate of cervical dilatation as described by Zhang et al. METHODS: Repeated-measures polynomial regression was used to create summary labour curves based on simulated cervical examinations. Interval-censored regression was used to create centimetre-by-centimetre estimates of rates of cervical dilatation and their 95^th centiles.

MAIN OUTCOME MEASURES: Labour summary curves and rates of cervical dilatation.

RESULTS: Repeated-measures polynomial regression did not detect the rapid acceleration in cervical dilatation (i.e. ‘acceleration phase’) and over-estimated lengths of labour, especially at smaller cervical dilatations. There was a two-fold overestimation in the mean rate of cervical dilatation from four to six centimetres. Interval-censored regression overestimated median transit-times, at four to five centimetres cervical dilatation or when cervical examinations occurred less than 0.5 to 1.5 hourly.

CONCLUSION: Repeated-measures polynomial regression and interval-censored regression should not be routinely used to define labour progress because they do not accurately reflect the underlying data.

ABSTRACT

BACKGROUND: Tinnitus severity has been exacerbated due to the COVID-19 pandemic and those with tinnitus require additional support. Such support should be informed by patient preferences and needs. The objective of this study was to gather information from individuals with tinnitus living in Europe to inform stakeholders of the (i) support they needed in relation to changes associated with the COVID-19 pandemic, and (ii) suggestions regarding tinnitus care for the future.

METHODS: A cross-sectional mixed methods study design was used using closed and open-ended questions via an online survey. Data was gathered from 710 adults experiencing tinnitus in Western Europe, with the majority living in The Netherlands, Belgium, and Sweden. Data were analysed using qualitative content analysis and descriptive statistics.

RESULTS: Those with tinnitus indicated the following support needs during the pandemic (a) support for tinnitus, (b) support for hearing-related difficulties, (c) social support, and (d) pandemic-related support. Five directions for future tinnitus care were provided, namely (a) need for understanding professional support and access to multidisciplinary experts, (b) greater range of therapies and resources, (c) access to more information about tinnitus, (d) prioritizing tinnitus research, and (e) more support for hearing protection and hearing loss prevention CONCLUSIONS: The findings point to the need for accessible (remote), patient-centred, suitable and evidence-based tinnitus care. Insights from the current study can be used by various stakeholders including clinical practitioners and tinnitus support services to ensure those with tinnitus have access to the help and support required in order to reduce service provision insufficiencies.

ABSTRACT

BACKGROUND: Mounting evidence supports an association between Guillain-Barré syndrome spectrum (GBSs) and severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection. However, GBSs in the setting of coronavirus disease-2019 (COVID-19) remains poorly characterized, while GBSs prevalence among COVID-19 patients has not been previously systematically evaluated using a meta-analytical approach.

METHODS: We performed a systematic review and meta-analysis of observational cohort and case-series studies reporting on the occurrence, clinical characteristics and outcomes of patients with COVID-19-associated GBSs. A random-effects model was used to calculate pooled estimates and odds ratios (ORs) with corresponding 95% confidence intervals (CIs), when comparing to non-COVID-19, contemporary or historical GBSs patients.

RESULTS: We identified 18 eligible studies (11 cohorts, 7 case-series) including a total of 136,746 COVID-19 patients. Among COVID-19 patients, including hospitalized and non-hospitalized cases, the pooled GBSs prevalence was 0.15‰ (95%CI:0-0.49‰; I² =96%). Compared to non-infected contemporary or historical controls, patients with SARS-CoV-2 infection had increased odds for demyelinating GBSs subtypes (OR=3.27; 95%CI: 1.32-8.09; I² =0%). In SARS-CoV-2 infected patients, olfactory or concomitant cranial nerve involvement was noted in 41.4% (95%CI:3.5-60.4%; I² =46%) and 42.8% (95%CI:32.8-53%; I² =0%) of the patients, respectively. Clinical outcomes including in-hospital mortality were comparable between COVID-19 GBSs patients and non-infected contemporary or historical GBSs controls.

CONCLUSIONS: GBSs prevalence was estimated at 15 cases per 100,000 SARS-CoV-2 infections. COVID-19 appears to be associated with an increased likelihood of GBSs and with demyelinating GBSs variants in particular.
