[PMID: 38433755 PMCID: PMC10904606 DOI: 10.3389/fcvm.2024.1360763] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/01/2024] [Accepted: 02/07/2024] [Indexed: 03/05/2024] Open
Abstract
Background The clinical prognosis of mitral valve surgery at morning, afternoon, and evening is not yet clear. The aim of the study is to investigate the impact of different time periods of surgery in the morning, afternoon and evening on the short-term and long-term results of mitral valve surgery. Methods From January 2018 to December 2020, 947 patients with mitral valve surgery in our department were selected. These patients were divided into 3 groups according to the starting time of surgery. Morning group (operation start time 8:00-10:30, n = 231), afternoon group (operation start time 12:00-14:30, n = 543), and evening group (operation start time 17:30-20:00, n = 173). The short-term and long-term results of the three groups were compared. Results There were no significant difference in the long-term mortality, long-term risk of stroke and reoperation. And there were no significant difference in in-hospital outcomes, including mortality, stroke, cardiopulmonary bypass time, aortic cross clamp time, mitral valve repair convert to mitral valve replacement, number of aortic cross clamp ≥2 times, unplanned secondary surgery during hospitalization (including thoracotomy hemostasis, thoracotomy exploration, redo mitral valve surgery, and debridement), intra-aortic balloon pump, extracorporeal membrane oxygenation, continuous renal replacement therapy, mechanical ventilation time, and intensive care unit length of stay. Conclusion There is no significant difference in the risk of short-term and long-term survival and adverse events after mitral valve surgery at different time periods in the morning, afternoon, and evening. Mitral valve surgery at night is safe.

Wen ZL, Zhou X, Peng D. The effect of surgical starting time on elective colorectal cancer surgery: A propensity score matching analysis. Medicine (Baltimore) 2024; 103:e37072. [PMID: 38306533 PMCID: PMC10843472 DOI: 10.1097/md.0000000000037072] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/17/2023] [Accepted: 11/14/2023] [Indexed: 02/04/2024] Open
Abstract
The purpose of the current study is to analyze whether surgical starting time affects the short-term outcomes of elective colorectal cancer (CRC) surgery. We retrospectively collected CRC patients who underwent elective surgery from Jan 2008 to Jan 2021 in a single clinical center. The effect of surgical starting time (morning surgery vs afternoon surgery, day surgery vs night surgery) on elective CRC surgery was analyzed using propensity score matching (PSM). A total of 6783 patients were included in the current study. There were 5751 patients in day surgery group and 1032 patients in night surgery group, and there were 2920 patients in morning surgery group and 2831 patients in afternoon surgery group. After 1:1 ratio PSM, there were no significant difference in terms of the baseline information (P > .05). Day surgery group had longer operation time (P = .000) and longer hospital stay (P = .029) than night surgery group after PSM. Morning surgery group had longer operation time than afternoon surgery group before PSM (P = .000) and after PSM (P = .000). Univariate and multivariate analysis of the total of 6783 patients were conducted to find predictors of complications, and found that night surgery was a predictor of major complications (P = .002, OR = 1.763, 95% CI = 1.222-2.543) but not a predictor of overall complications (P = .250, OR = 1.096, 95% CI = 0.938-1.282). Night surgery is a predictor of major complications after elective CRC surgery, therefore, surgeons should be careful when operating at night.

Abstract
Technological progress, such as the launching of a new generation of drug-coated stents as well as new antiplatelet drugs, has resulted in the treatment of myocardial infarction (MI) becoming much more effective. The aim of this study was to assess in-hospital mortality and to conduct an assessment of risk factors relevant to the in-hospital death of patients with MI. This study was based on an observational hospital registry of patients with MI (ACS GRU registry). For the purpose of the statistical analysis of the risk factors of death, a univariate logistic regression model was applied. In-hospital general mortality amounted to 7.27%. A higher death risk was confirmed in the following cases: (1) serious adverse events (SAEs) that occurred during the procedure; (2) patients transferred from another department of a hospital (OR = 2.647, p = 0.0056); (3) primary percutaneous coronary angioplasty performed on weekdays between 10 p.m. and 8 a.m. (OR = 2.540, p = 0.0146). The influence of workload and operator experience on the risk of death in a patient with MI has not been confirmed. The results of this study indicate the increasing importance of new risk factors for in-hospital death in patients with MI, such as selected logistical aspects of the MI treatment process and individual SAEs.

Abstract
This systematic review and meta-analysis aimed to evaluate patients with acute ST-segment elevation myocardial infarction (STEMI) who were admitted during off-hours and treated with primary angioplasty associated with an increased risk of mortality compared with those admitted during regular working hours. We performed a systematic literature search using PubMed, SCOPUS, Europe PMC, and Cochrane CENTRAL databases that was finalized on March 15, 2021. The primary outcome was mortality comprising early (in-hospital), midterm (30 days to 1 year), and long-term mortality (>1 year). A total of 384,452 patients from 56 studies were included. The overall mortality of acute STEMI patients admitted during off-hours and regular hours were 6.1 and 6.7%, respectively. Patients admitted during off-hours had similar risk of early, midterm, and long-term mortality compared to those admitted during regular working hours ([relative risk or RR = 1.07, 95% confidence interval or CI, 1.00-1.14, p = 0.06; I 2 = 45%, p = 0.0009], [RR = 1.00, 95% CI, 0.95-1.05, p = 0.92; I 2 = 13%, p = 0.26], and [RR = 0.95, 95% CI, 0.86-1.04, p = 0.26; I 2 = 0%, p = 0.76], respectively). Subgroup analyses indicated that the results were consistent across all subgroups ([women vs. men], [age >65 years vs. ≤65 years], and [Killip classification II to IV vs. Killip I]). Funnel plot was asymmetrical. However, Egger's test suggests no significance of small-study effects ( p = 0.19). This meta-analysis showed that patients with acute STEMI who were admitted during off-hours and treated with primary angioplasty had similar risk of early, midterm, and long-term mortality compared with those admitted during regular working hours.

[PMID: 34970604 PMCID: PMC8712470 DOI: 10.3389/fcvm.2021.752675] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2021] [Accepted: 11/18/2021] [Indexed: 01/14/2023] Open
Abstract
Objectives: Out-of-hour admission (on weekends, holidays, and weekday nights) has been associated with higher mortality in patients with acute myocardial infarction (AMI). We conducted a meta-analysis to verify the association between out-of-hour admission and mortality (both short- and long-term) in AMI patients. Design: This Systematic review and meta-analysis of cohort studies. Data Sources: PubMed and EMBASE were searched from inception to 27 May 2021. Eligibility Criteria for Selected Studies: Studies of any design examined the potential association between out-of-hour admission and mortality in AMI. Data Extraction and Synthesis: In total, 2 investigators extracted the data and evaluated the risk of bias. Analysis was conducted using a random-effects model. The results are shown as odds ratios [ORs] with 95% confidence intervals (CIs). I2 value was used to estimate heterogeneity. Grading of Recommendations Assessment, Development, and Evaluation was used to assess the certainty of the evidence. Results: The final analysis included 45 articles and 15,346,544 patients. Short-term mortality (defined as either in-hospital or 30-day mortality) was reported in 42 articles (15,340,220 patients). Out-of-hour admission was associated with higher short-term mortality (OR 1.04; 95%CI 1.02–1.05; I2 = 69.2%) but there was a significant statistical indication for publication bias (modified Macaskill's test P < 0.001). One-year mortality was reported in 10 articles (1,386,837 patients). Out-of-hour admission was also associated with significantly increased long-term mortality (OR 1.03; 95%CI 1.01–1.04; I2 = 66.6%), with no statistical indication of publication bias (p = 0.207). In the exploratory subgroup analysis, the intervention effect for short-term mortality was pronounced among patients in different regions (p = 0.04 for interaction) and socio-economic levels (p = 0.007 for interaction) and long-term mortality was pronounced among patients with different type of AMI (p = 0.0008 for interaction) or on different types of out-to-hour admission (p = 0.006 for interaction). Conclusion: Out-of-hour admission may be associated with an increased risk of both short- and long-term mortality in AMI patients. Trial Registration: PROSPERO (CRD42020182364).

Abstract
BACKGROUND AND OBJECTIVE To facilitate timely surgery and efficient use of operating room time, our practice uses a team-based approach so patients may undergo primary rhegmatogenous retinal detachment (RRD) surgery with a different surgeon instead of the diagnosing surgeon. PATIENTS AND METHODS This was a retrospective cohort study of 331 eyes that underwent RRD surgery. Patients were divided into two groups: RRD surgery performed by the diagnosing surgon, and RRD surgery performed by a different surgeon. RESULTS Of 331 eyes, 200 eyes (60.4%) were repaired by the diagnosing surgeon and 131 eyes (39.6%) were repaired by a different surgeon. Primary anatomic success (PAS) rates at 3 months postoperatively were equivalent between the two groups (87.0% and 87.8% in the diagnosing surgeon and different surgeon groups, respectively [P = .83]). There was no significant difference in preoperative (P = .08) or final (P = .28) visual acuity between the groups. Time between diagnosis and RRD repair was shorter in the different surgeon group (median of 1.5 days [IQR: 1.0-3.6] in the surgeon group versus 2.2 days [IQR: 0.8-5.7] in the diagnosing surgeon group) (P = .03). Logistic regression analysis gave no evidence to suggest that PAS rates depended on day of week, time of day surgery was performed, group, or the interaction between those factors (P = .93). CONCLUSIONS Visual and anatomic success in RRD repair are equivalent when surgery is performed by either the diagnosing surgeon or a surgical colleague because time to surgery is reduced. Neither time of day nor day of the week had any influence on the outcomes. [Ophthalmic Surg Lasers Imaging Retina. 2021;52:560-566.].

Abstract
Purpose The purpose of the present study was to evaluate the effect of time (season, surgical starting time in the daytime, preoperative waiting time) on patients with gastric cancer. Methods A retrospective collection of medical records of patients who underwent gastrectomy at a single clinical center from January 2013 to December 2018 was performed. Medical records were collected, and short-term outcomes and long-term survival were analyzed by different time groups. Results A total of 586 patients were included in this study. In terms of surgical starting time, the midday group had a shorter operation time (p=0.017) but more complications (p=0.048) than the non-midday group. No significant difference was found based on the season of gastrectomy. The long preoperative waiting group had a shorter postoperative hospital stay than the short waiting group (p=0.026). No significant difference was found between the short-waiting group and long-waiting group in overall survival for all clinical stages. Age (p=0.040, HR=1.017, 95% CI=1.001-1.033), BMI (p<0.001, HR=0.879, 95% CI=0.844-0.953) and clinical stage (p<0.001, HR=2.053, 95% CI=1.619-2.603) were independent prognostic factors predicting overall survival; however, season of gastrectomy, surgical starting time and preoperative waiting time were not identified as independent prognostic factors. Conclusion Surgical starting time at the midday could cause more complications, and surgeons should be careful when the surgical starting time is midday.

Abstract
Background The increase in the incidence of esophageal cancers (ECs) combined with fewer surgeons working at large centers will increase the likelihood of surgery for ECs being performed during later hours. This study aimed to compare esophagectomies’ operative outcomes for EC performed at different surgical starting times. Methods This was a single-center, retrospective study. Risk-adjusted cumulative sum curve analysis and Cox regression analysis were used to identify the potential change-point of surgical starting times. The participants were then divided into 2 groups according to the change-point time. Propensity score matching was used to control confounding factors between the 2 groups. We compared the short- and long-term outcomes in both groups. Results A total of 702 patients who underwent potentially radical esophagectomy from 7 May 2014 to 31 December 2017 in our institute were included. The 3-year all-cause mortality showed a significant change-point at 16:42, with an increment from 56.5% to 76.9% (P=0.043). Esophagectomy that commenced between 17:00–18:59 was associated with significantly lower overall survival (OS) [multivariate hazard ratio (HR): 2.47; 95% confidence interval (CI): 1.25 to 4.90; P=0.010] and disease-free survival (DFS) (multivariate HR: 2.14; 95% CI: 1.08 to 4.21; P=0.028). The participants were allocated to the during-hours group and the after-hours group according to the change-point of 17:00. A total of 84 participants in the during-hours group were matched to 33 participants in the after-hours group. The median operative time was shorter in the after-hours group [309 (during-hours) vs. 239 (after-hours) minutes, P=0.014); the after-hours group had a greater incidence of respiratory complications (22.63% vs. 45.45%, P=0.023) and 90-day mortality (0 vs. 9.09%, P=0.021). The 5-year OS (P=0.042) and DFS (P=0.030) were significantly higher in the during-hours group. Conclusions Esophagectomies started during after-hours are correlated with poorer surgical outcomes. It is recommended to cancel selective esophagectomies due to commence after 17:00.

Comparison of the Characteristics of Coronary Interventions Performed During Day and Night Shifts in Patients with Acute Myocardial Infarction. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17155378. [PMID: 32722586 PMCID: PMC7432738 DOI: 10.3390/ijerph17155378] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 05/18/2020] [Revised: 07/20/2020] [Accepted: 07/22/2020] [Indexed: 11/16/2022]
Abstract
Therapeutic percutaneous coronary intervention (PCI) is the treatment of choice in acute myocardial infarction (AMI). If optimally performed, PCI reduces myocardial injury and improves the likelihood of a positive clinical outcome. Therefore, the equal quality of PCI throughout both day and night shifts is of paramount importance. Our aim was to compare urgent diagnostic and therapeutic coronary interventions performed during day and night shifts. We retrospectively analyzed the medical records of 144 patients who underwent coronary angiography for AMI over six months in a tertiary referral center working in 24/7 mode. The patients' characteristics, procedural data and the operator's experience in interventional cardiology were compared according to the time of intervention during a day shift (8 a.m. until 8 p.m., group A, n = 106) and night shift (from 8 p.m. until 8 a.m. next day, group B, n = 36). The baseline characteristics of the subjects of groups A and B were similar, except for a higher proportion of AMI without persistent ST-segment elevation (NSTEMI) in patients who underwent coronary angiography during regular working hours compared to off-hours (58% vs. 34%, p < 0.05). The average time of diagnostic coronary angiography was longer by about 5 min during the day shift (28.5 ± 12.2 vs. 23.8 ± 8.9 min, p < 0.05), while other procedural data, including the arterial access route, the number of catheters needed and the contrast-medium volume, were similar. The use of additional diagnostic tools for coronary lesion assessment (intracoronary ultrasound or fractional flow reserve measurement) was almost twice as frequent during regular working hours (15% vs. 8%). Urgent therapeutic PCI on the culprit artery was performed in 79% and 89% of group A and B patients, respectively. The groups did not differ in procedural characteristics regarding the total interventional session, including both diagnostic angiography and therapeutic PCI, such as total procedure duration, fluoroscopy time, radiation dose, stenting technique and total stent length. Coronary thrombectomy or rotational atherectomy were more frequently used in group A (27% vs. 15%, p = 0.16). The percentage of doctors with the least experience in interventional cardiology was, albeit insignificantly, lower during day shifts (31% vs. 42%). In conclusion, the majority of clinical and periprocedural characteristics appeared to be independent of intervention time, except for a longer duration of diagnostic coronary angiography during daytime. This finding could probably result from a higher proportion of NSTEMI patients frequently requiring additional angiographic projections and special techniques to properly identify the infarct-related artery during the day shift. Whether a tendency of less frequent use of additional tools at off-hours may also be due to a lower percentage of NSTEMI interventions at night, or whether this can be linked to lower availability of experienced operators, remains to be validated in a large study. The latter possibility, if confirmed, might encourage public health authorities and healthcare organizers to improve off-hours cathlab staffing with experienced interventionalists. Finally, additional obligatory training in special diagnostic and therapeutic invasive techniques might be advisable for the least experienced operators scheduled to work night shifts.

Abstract
Biological rhythms exist in organisms at all levels of complexity, in most organs and at myriad time scales. Our own biological rhythms are driven by energy emitted by the sun, interacting via our retinas with brain stem centres, which then send out complex messages designed to synchronize the behaviour of peripheral non-light sensing organs, to ensure optimal physiological responsiveness and performance of the organism based on the time of day. Peripheral organs themselves have autonomous rhythmic behaviours that can act independently from central nervous system control but is entrainable. Dysregulation of biological rhythms either through environment or disease has far-reaching consequences on health that we are only now beginning to appreciate. In this review, we focus on cardiovascular rhythms in health, with ageing and under disease conditions.

Abstract
Gastric cancer (GC) continues to be 1 of the malignant tumors with high morbidity and mortality worldwide. Although the improvements in targeted inhibitor therapy have promoted survival, the first choice for GC patients is still surgery. However, prolonged surgery may tire surgeons and affect surgical outcomes.To detect whether different time-of-day radical gastrectomy influenced short-term and long-term surgical outcomes.This study included 117 patients between 2008 and 2012 who underwent a radical gastrectomy. These patients were grouped into the morning (before 13:00) and afternoon (after 13:00) groups or divided into 2 groups according to the median operation start time (before or after 11:23). Then, the relevant influence of the surgical start time was analyzed.The morning group (before 13:00) and the front median group (before 11:23) showed longer operative time (P = .008 and P = .016, respectively), lower estimated blood loss (P < .001 and P = .158, respectively), and longer time before resuming oral intake (P < .001 and P < .173, respectively) than the afternoon group (after 13:00) or latter median group (after 11:23). Starting the operation in the morning had no effect on the rate of postoperative complications. The operation start time had no significant influence on the overall survival of patients who underwent a radical gastrectomy. However, in subgroup analysis, patients who underwent a distal gastrectomy faced poor prognosis when their surgery started after 13:00 (P = .030).The results suggest that the operation start time might be an indicator of total operative time, estimated blood loss, and the time to resuming oral intake. The operation start time may also influence the prognosis of radical gastrectomy in patients with GC.

Abstract
Background Conflicting data exist regarding the outcomes of primary percutaneous coronary intervention (PCI) for ST-segment elevation myocardial infarction (STEMI) based on intervention timings. It is believed that short staffing at night hours may lead to a lapse in the delivery of effective, efficient and timely medical intervention. Methods A retrospective single-center study was performed, and a total of 436 patients were randomized into two groups. Group A had 279 patients who had the heart catheterization done during the daytime (between 6 am and 6 pm), while group B had 157 patients who had the same intervention performed at night (between 6 pm and 6 am). Results Door to balloon (DTB) time during the day was about 16 min shorter than the DTB time at night (81.29 ± 3.26 vs. 97.30 ± 8.54) with no statistical difference (P = 0.051). The mean troponin rise during the day was 1.94 ± 10.60 SEM (95% confidence interval (CI): -22.70 to 18.90) higher than night troponin levels (71.75 ± 7.18 vs. 69.80 ± 7.18), but P value was 0.85. The left ventricular ejection fraction (LVEF) fall for daytime was 0.93% vs. 0.90% for night time patients (P = 0.94). Conclusion There is no significant difference in the mean DTB time, the rise in troponin, fall in LVEF, readmission rates, or mortality, and hence no negative effects on patient outcomes based on the patient's time of presentation between the two groups.

Abstract
BACKGROUND Gastric cancer continues to be one of the malignant tumor types with high morbidity and mortality worldwide. Although remarkable improvements have been made to combat gastric cancer, surgery is still the first choice of treatment for gastric cancer. METHODS This was a single-center and retrospective study. A total of 110 patients who underwent radical gastrectomy with D2 lymph node dissection between 2014 and 2017 were included in this study, and all patients were treated by the same medical staff. Based on the median operating time, patients were grouped into a long-time group (>180 min) and a short-time group (≤180 min). Influences of operating time on outcomes of patients in the short-term and long-term groups were analyzed. RESULTS The long-time group showed a higher incidence of postoperative complications compared with the short time group (P < 0.01) with a significant decrease in serum albumin and the prognostic nutritional index value. Moreover, a long operating time was often caused by the operating start time (P < 0.001), excision difficulty caused by lager tumor size (P < 0.001), worse tumor differentiation, and deeper tumor invasion (P < 0.05). However, length of operating time did not significantly influence overall survival of patients who underwent radical gastrectomy. CONCLUSIONS The results suggested that operating time might be an indicator of the incidence of postoperative complication and that several important variables, such as prognostic nutritional index, serum albumin, operating start time, and excision time, could be intervened in the perioperative period to help patients gain a better outcome after gastrectomy.

Abstract
BACKGROUND Several studies have shown contradictive findings regarding mortality and hospital admission time in patients presenting with ST-elevation myocardial infarction (STEMI). The aim of this study was to assess the impact of "on-" or "off-hour" admission on short- and long-term all-cause mortality of patients in the advanced Vienna STEMI network between 2003 and 2009. METHODS AND RESULTS In total, 2829 patients were included into this analysis. Patients were stratified according to admission time into "on-hour" admission (07:30 until 15:00h on weekdays) and "off-hour" admission (15:00-7:30h on weekdays and 24h on weekends). As endpoint of interest, all-cause mortality was investigated after 30days and 3years of follow-up, the latter for all patients and as Landmark analysis for survivors of the index event. Mean age was 60.5±13.3years, 2048 (72.4%) patients were male and 1260 (44.5%) patients presented with anterior wall infarction. 683 (24.1%) patients were admitted "on-hours", 2146 (75.9%) patients were admitted "off-hours". All-cause death occurred in 176 (6.2%) patients after a follow-up of 30days and in 337 (11.9%) patients after 3years. For short- and long-term all-cause mortality no significant differences could be detected between "on-" and "off-hour" admission in univariate and multivariate Cox proportional hazard analyses as well as for propensity score adjusted outcome analysis. CONCLUSION In the Vienna STEMI network, "on-" or "off-hour" admission had no impact on short- and long-term mortality for all-comers presenting with acute STEMI. Our findings confirm the imperative need for well-structured STEMI networks of care, as previous data repeatedly demonstrated increased adverse cardiovascular outcome for "off-hour" admission.

Abstract
BACKGROUND The association between off-hours presentation and mortality in patients with ST-segment elevation myocardial infarction (STEMI) remains unclear. We performed a meta-analysis to assess the impact of off-hours presentation on short- and long-term mortality among STEMI patients. METHODS We searched PubMed, EMBASE, and the Cochrane Library from their inception to 10 July 2016. Studies were eligible if they evaluated the relationship of off-hours (weekend and/or night) presentation with short- and/or long-term mortality. RESULTS A total of 30 studies with 33 cohorts involving 192,658 STEMI patients were included. Off-hours presentation was associated with short-term mortality (odds ratio [OR] 1.07, 95% confidence interval [CI] 1.02-1.12, P = 0.004) but not with long-term mortality (OR 1.00, 95% CI 0.94-1.07, P = 0.979). No significant heterogeneity was observed. The outcomes remained the same after sensitivity analyses and trim and fill analyses. Subgroup analyses showed that STEMI patients undergoing primary percutaneous coronary intervention do not have a higher risk of short-term mortality (OR 1.061, 95% CI 0.993-1.151). In addition, higher mortality was observed only during hospitalization (OR 1.072, 95% CI 1.022-1.125), not at the 30-day, 1-year or long-term follow-ups. CONCLUSIONS Off-hours presentation was associated with an increase in short-term mortality, but not long-term mortality, among STEMI patients. Clinical approaches to decrease short-term mortality regardless of the time of presentation should be evaluated in future studies.

Abstract
Previous studies have reported worse outcomes and longer door-to-balloon times (DBTs) in patients presenting with ST-elevation myocardial infarction (STEMI) after normal working hours, during weekends, and on holidays (off-hours) compared with normal business hours (on-hours). Recent studies, however, have reported similar outcomes regardless of presentation time. MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials were queried from January 1990 through December 2016. Only studies comparing STEMI outcomes during off-hours versus on-hours with percutaneous coronary intervention were included. A random-effects meta-analysis model was used to pool outcomes across the studies. Clinical end points included short- (<30 days of presentation), intermediate- (at 1 to 2 years), and long-term (at 3 to 4 years) stent thrombosis, mortality, recurrent myocardial infarction (MI), and major adverse cardiovascular events (MACEs). A total of 86,776 patients (62 years and 74.5% male) were identified from 39 studies. There was no significant difference between both groups with regard to mean DBT (odds ratio [OR] 0.74, 95% confidence interval [CI] -2.73 to 4.22, p = 0.67) or median DBT (p = 0.19). There was no significant difference between the 2 groups for short-term end points including mortality (OR 1.11, 95% CI 0.99 to 1.25, p = 0.08), MI (OR 1.25, 95% CI 0.90 to 1.74, p = 0.18), MACE (OR 1.06, 95% CI 0.93 to 1.20, p = 0.40), or stent thrombosis (OR 1.23, 95% CI 0.83 to 1.82, p = 0.31). Similarly, intermediate-term end points were not statistically different for mortality (OR 0.97, 95% CI 0.89 to 1.05, p = 0.46), MI (OR 0.86, 95% CI 0.73 to 1.02, p = 0.08), or MACE (OR 1.00, 95% CI 0.92 to 1.08, p = 0.98). Long-term end points did not differ statistically between groups for mortality (OR 0.95, 95% CI 0.83 to 1.09, p = 0.46), MI (OR 1.19, 95% CI 0.77 to 1.84, p = 0.44), or MACE (OR 0.98, 95% CI 0.89 to 1.08, p = 0.67). In conclusion, patients presenting with STEMI during off-hours and treated with percutaneous coronary intervention had similar short-, intermediate-, and long-term outcomes compared with patients presenting during on-hours. DBT was not affected by the time of presentation.

Abstract
BACKGROUND Regional healthcare projects improve the off-hour care of patients with acute coronary syndromes and persistent ST-segment elevation myocardial infarction (STEMI). To analyse differences in quality of care between on and off-hour care of STEMI patients admitted to certified German chest pain units. METHODS A total of 1107 STEMI patients from the German chest pain unit registry were enrolled. Analyses comprised critical time intervals (symptoms to first medical contact (FMC), FMC to admission, symptoms to admission, symptoms to balloon, FMC to balloon, door to balloon times) and major adverse cardiac and cerebrovascular events at follow-up. RESULTS 54.8% of patients were admitted off-hours. Symptoms to admission (2:28 (1:28-5:20 h) vs. 3:16 h (1:35-8:06 h), P<0.001), symptoms to FMC (1:15 h (0:33-3:00 h) vs. 2:00 h (0:40-6:46 h), P<0.001) and FMC to admission intervals (0:45 h (0:30-1:20 h) vs. 0:52 h (0:32-1:35 h), P=0.09) were shorter during off-hours. Percutaneous revascularisation rates were high and without difference between on and off-hours (95.5% vs. 96.8%, P=0.30). Door to balloon times were significantly less during on-hours (0:32 h (0:18-1:06 h) vs. 0:44 h (0:23-1:20 h), P<0.01) without negative impact on the proportion of patients with a door to balloon time of <60 min (72.6% vs. 68.4%, P=0.19), symptoms to balloon (3:49 h (2:12-10:46 h) vs. 3:30 h (2:04-7:41 h), P=0.08) or FMC to balloon times (1:26 h (0:56-2:22 h) vs. 1:30 h (1:03-2:29 h), P=0.14). Major adverse cardiac and cerebrovascular event rates did not differ significantly between on and off-hours (log-rank test P=0.36). CONCLUSIONS The German chest pain unit network ensures rapid and structured preclinical and in-hospital care independent from the circadian variation of admission. Slower door to balloon times off-hours are compensated by faster symptoms to admission or symptoms to FMC intervals. Further efforts should focus on patient awareness programmes on-hours and STEMI alarming tracks off-hours.

Abstract
BACKGROUND Surgical care is delivered 24 h a day at most institutions. Alarmingly, some authors have found that certain operative start times are associated with greater morbidity and mortality rates. This effect has been noted in both the public and private sector. Although some of these differences may be related to process, they may also be caused by the human circadian rhythm and corresponding changes in host defenses. We hypothesized that the time of day of an operation would impact the frequency of certain post-operative outcomes significantly. METHODS Cases at a single tertiary-care center reported to the American College of Surgeons National Surgical Quality Improvement Program over a 10-year period were identified. Operative start times were divided into six-hour blocks, with 6 am to noon serving as the reference. Standard univariable techniques were applied. Multivariable logistic regression with mixed effects modeling then was used to determine the relation between operative start times and infectious outcomes, controlling for surgeon clustering. Statistical significance was set at p < 0.01. RESULTS A total of 21,985 cases were identified, of which 2,764 (12.6%) were emergency procedures. Overall, 9.7% (n = 2,142) of patients experienced some post-operative infectious complication. Seventy percent of these infections (n = 1,506) were surgical site infections. On univariable analysis considering all cases, nighttime and evening operations had higher rates of post-operative infections than those in performed during the day (9.1% from 6 am to noon; 9.7% from noon to 6 pm; 14.8% from 6 pm to midnight; and 14.4% from midnight to 6 am; p < 0.001). On multivariable analysis, operative start time was not associated with the risk of post-operative infection, even when emergency cases were considered independently. CONCLUSION Our data suggest that operative start times have no correlation with post-operative infectious complications. Further work is required to identify the source of the time-dependent outcome variability observed in previous studies.

Abstract
IMPORTANCE Thousands of physicians attend scientific meetings annually. Although hospital physician staffing and composition may be affected by meetings, patient outcomes and treatment patterns during meeting dates are unknown. OBJECTIVE To analyze mortality and treatment differences among patients admitted with acute cardiovascular conditions during dates of national cardiology meetings compared with nonmeeting dates. DESIGN, SETTING, AND PARTICIPANTS Retrospective analysis of 30-day mortality among Medicare beneficiaries hospitalized with acute myocardial infarction (AMI), heart failure, or cardiac arrest from 2002 through 2011 during dates of 2 national cardiology meetings compared with identical nonmeeting days in the 3 weeks before and after conferences (AMI, 8570 hospitalizations during 82 meeting days and 57,471 during 492 nonmeeting days; heart failure, 19,282 during meeting days and 11,4591 during nonmeeting days; cardiac arrest, 1564 during meeting days and 9580 during nonmeeting days). Multivariable analyses were conducted separately for major teaching hospitals and nonteaching hospitals and for low- and high-risk patients. Differences in treatment utilization were assessed. EXPOSURES Hospitalization during cardiology meeting dates. MAIN OUTCOMES AND MEASURES Thirty-day mortality, procedure rates, charges, length of stay. RESULTS Patient characteristics were similar between meeting and nonmeeting dates. In teaching hospitals, adjusted 30-day mortality was lower among high-risk patients with heart failure or cardiac arrest admitted during meeting vs nonmeeting dates (heart failure, 17.5% [95% CI, 13.7%-21.2%] vs 24.8% [95% CI, 22.9%-26.6%]; P < .001; cardiac arrest, 59.1% [95% CI, 51.4%-66.8%] vs 69.4% [95% CI, 66.2%-72.6%]; P = .01). Adjusted mortality for high-risk AMI in teaching hospitals was similar between meeting and nonmeeting dates (39.2% [95% CI, 31.8%-46.6%] vs 38.5% [95% CI, 35.0%-42.0%]; P = .86), although adjusted percutaneous coronary intervention (PCI) rates were lower during meetings (20.8% vs 28.2%; P = .02). No mortality or utilization differences existed for low-risk patients in teaching hospitals or high- or low-risk patients in nonteaching hospitals. In sensitivity analyses, cardiac mortality was not affected by hospitalization during oncology, gastroenterology, and orthopedics meetings, nor was gastrointestinal hemorrhage or hip fracture mortality affected by hospitalization during cardiology meetings. CONCLUSIONS AND RELEVANCE High-risk patients with heart failure and cardiac arrest hospitalized in teaching hospitals had lower 30-day mortality when admitted during dates of national cardiology meetings. High-risk patients with AMI admitted to teaching hospitals during meetings were less likely to receive PCI, without any mortality effect.

Abstract
OBJECTIVE To assess the association between off-hour (weekends and nights) presentation, door to balloon times, and mortality in patients with acute myocardial infarction. DATA SOURCES Medline in-process and other non-indexed citations, Medline, Embase, Cochrane Database of Systematic Reviews, and Scopus through April 2013. STUDY SELECTION Any study that evaluated the association between time of presentation to a healthcare facility and mortality or door to balloon times among patients with acute myocardial infarction was included. DATA EXTRACTION Studies' characteristics and outcomes data were extracted. Quality of studies was assessed with the Newcastle-Ottawa scale. A random effect meta-analysis model was applied. Heterogeneity was assessed using the Q statistic and I(2). RESULTS 48 studies with fair quality, enrolling 1,896,859 patients, were included in the meta-analysis. 36 studies reported mortality outcomes for 1,892,424 patients with acute myocardial infarction, and 30 studies reported door to balloon times for 70,534 patients with ST elevation myocardial infarction (STEMI). Off-hour presentation for patients with acute myocardial infarction was associated with higher short term mortality (odds ratio 1.06, 95% confidence interval 1.04 to 1.09). Patients with STEMI presenting during off-hours were less likely to receive percutaneous coronary intervention within 90 minutes (odds ratio 0.40, 0.35 to 0.45) and had longer door to balloon time by 14.8 (95% confidence interval 10.7 to 19.0) minutes. A diagnosis of STEMI and countries outside North America were associated with larger increase in mortality during off-hours. Differences in mortality between off-hours and regular hours have increased in recent years. Analyses were associated with statistical heterogeneity. CONCLUSION This systematic review suggests that patients with acute myocardial infarction presenting during off-hours have higher mortality, and patients with STEMI have longer door to balloon times. Clinical performance measures may need to account for differences arising from time of presentation to a healthcare facility.

Abstract
Background Primary percutaneous coronary intervention (PCI) is a proven therapy for acute ST-segment elevation myocardial infarction. However, outcomes associated with primary PCI may differ depending on time of day. Methods and results Using the Alberta Provincial Project for Outcomes Assessment in Coronary Heart Disease, a clinical data-collection initiative capturing all cardiac catheterisation patients in Alberta, Canada, the authors described and compared crude and risk-adjusted survival for ST-segment elevation myocardial infarction patients undergoing primary PCI after-hours versus regular working hours. From 1 January 1999 to 31 March 2006, 1664 primary PCI procedures were performed (54.4% after-hours). Mortalities at 30 days were 3.6% for regular hours procedures and 5.0% for after-hours procedures (p=0.16). 1-year mortalities were 6.2% and 7.3% in the regular hours and after-hours groups, respectively (p=0.35). After adjusting for baseline risk factor differences, HRs for after-hours mortality were 1.26 (95% CI 0.78 to 2.02) for survival to 30 days and 1.08 (0.73 to 1.59) for survival to 1 year. A meta-analysis of our after-hours HR point estimate with other published risk estimates for after hours primary PCI outcomes yielded an RR of 1.23 (1.00 to 1.51) for shorter-term outcomes. Conclusions After-hours primary PCI was not associated with a statistically significant increase in mortality. However, a meta-analysis of this study with other published after-hours outcome studies yields an RR that leaves some questions about unexplored factors that may influence after-hours primary PCI care.

Abstract
BACKGROUND Mortality and complications after percutaneous coronary intervention is higher when performed after regular duty hours due to challenging patient characteristics, inferior processes of care and limited resources. Since these challenges are also encountered during coronary artery bypass graft (CABG) surgery that is performed after regular work hours, we assessed whether hour and day of procedure influenced mortality after CABG. METHODS We studied 4,714 consecutive patients who underwent CABG at the Minneapolis Veterans Administration (VA) Medical Center between 1987 and 2009. We compared postoperative (30-day) mortality rates in relation to hour and day in which the operation was performed. RESULTS Operations performed on weekends and after 4 PM had higher risk patients (p < 0.0001) and were more likely to be emergent (p < 0.0001), require intra-aortic balloon pump support (p < 0.0001) and result in postoperative complications (p < 0.0001) compared to those at regular work hours. Mortality was significantly higher when CABG was performed on weekends compared to weekdays (9.4% versus 2.5%; odds ratio (OR) 4.1, 95% confidence interval (CI) 1.6 to 10.4, p = 0.003), and after 4 PM compared to between 7 AM-4 PM (6.2% versus 2.2%; OR 2.9, 95% CI 1 to 8, p = 0.049). In multivariable analysis, when adjusted for the urgency of the operation and the VA estimated mortality risk score, these associations were no longer statistically significant. CONCLUSIONS Mortality after CABG is higher when surgery is performed on the weekends and after 4 PM. These variations in mortality were related to higher patient risk, and urgency of the operation rather than external factors.

Abstract
BACKGROUND AND OBJECTIVES Although circadian variation in the onset of acute myocardial infarction (AMI) has been reported in a number of studies, not much is known about the impact of circadian variation on 12-month mortality. The aim of this study was to investigate the impact of circadian variation on 12-month mortality in patients with AMI. SUBJECTS AND METHODS Eight hundred ninety two patients (mean age 67±12; 66.1% men) with AMI who visited Kyungpook National University Hospital from November 2005 to December 2007 were included in this study. Patients were divided into groups based on four 6-hours intervals: overnight (00:00-05:59); morning (06:00-11:59); afternoon (12:00-17:59) and evening (18:00-23:59). RESULTS Kaplan-Meier survival curves showed 12-month mortality rates of 9.6%, 9.1%, 12.1%, and 16.7% in the overnight, morning, afternoon, evening-onset groups, respectively (p=0.012). Compared with the morning-onset AMI group, the serum creatinine levels (p=0.002), frequency of Killip class ≥3 (p=0.004), and prescription rate of diuretics (p=0.011) were significantly higher in the evening-onset AMI group, while the left ventricular ejection fraction (p=0.012) was significantly lower. The proportion of patients who arrived in the emergency room during routine duty hours was significantly lower in evening-onset groups irrespective of the presence or absence of ST-segment elevation (p<0.001). According to univariate analysis, the 12-month mortality rate in the evening group was significantly higher compared to the morning group (hazard ratio 1.998, 95% confidence interval 1.196 to 3.338, p=0.008). CONCLUSION Patients with evening-onset AMI had poorer baseline clinical characteristics, and this might affect the circadian impact on 12-month mortality. Further studies are needed to clarify the role of circadian variation on the long-term outcome of AMI.

Abstract
It has been well established that there exists a circadian concentration of cardiovascular, cerebrovascular and cardiopulmonary events. The aim was to describe aspects of circadian variation in relation to cardiovascular, cerebrovascular and thromboembolic diseases and to describe the literature concerning post-operative circadian disturbances. We also present the literature concerning circadian variation in post-operative morbidity and mortality. PubMed and the Cochrane database were searched for papers using a combination of 'circadian,''surgery,''post-operative,''mortality' and 'morbidity.' Eleven relevant studies were found, and seven of these were excluded due to the use of time of surgery and not time of morbidity or mortality as the main variable. The results from the four articles showed a circadian distribution of morbidity and mortality that mimics the one seen without surgery. There is a peak incidence of myocardial ischemia, fatal thromboembolism and sudden unexpected death in the morning hours. A circadian variation exists in post-operative morbidity and mortality. The observed circadian variation in post-operative morbidity and mortality may warrant a chronopharmacological approach to patients in the perioperative period. The underlying pathophysiological mechanisms should be the focus for future studies.

Abstract
AIM To analyze the efficacy of a regionally organized primary percutaneous coronary intervention (PCI) network at the Heart Center, Semmelweis University Budapest, part of the "Budapest model," and the factors that influence it. METHODS In order to investigate the differences between regular and off-hours patient care in a 24-hour myocardial infarction primary care system, we included 1890 consecutive, unselected patients with ST-segment elevation myocardial infarction and followed them until at least one year. The follow-up was complete for all participants. RESULTS The difference between regular hours and off-hours mortality was not significant either after 30 days (8.6% vs 8.8%, respectively) or after 1 year (15.3% vs 14.7%, respectively). The rate of patients with re-infarction, frequency of re-intervention, and major adverse cardiac events, including death, re-infarction, re-intervention, and coronary artery bypass graft surgery, were similar in both patient groups. The time delay between the onset of chest pain and arrival to the clinic was 5.9+/-5.8 hours (mean+/- standard deviation) during regular hours and 5.2+/-4.6 hours during off-hours (P=0.235). Direct transport caused significant decrease in the 30-day and 1-year mortality independent of duty time (7.2% vs 9.9%, P=0.027; 12.6% vs 16.7%, P=0.028; respectively). CONCLUSION Centralized primary PCI network of the "Budapest model" achieved the same level of patient care during both off-hours and regular hours.

Abstract
BACKGROUND Studies about the influence of various factors on clinical therapy and course in acute coronary syndromes have shown that the outcome is related to admission time to the hospital, with an impaired prognosis in patients admitted out of regular working hours. However little is known about the impact of admission on weekend in hospitals with catheterisation laboratories. METHODS We analyzed data of the prospective MITRA-PLUS registry of 11,516 patients with ST-elevation myocardial infarction (STEMI) admitted to hospitals with catheterization facilities for differences of in-hospital mortality between patients admitted during regular working hours, at night and on weekends. RESULTS The prehospital delay and "door-to-balloon"-time were significantly longer on weekends and at nights than at regular working hours (median 196 Vs. 240 Vs. 155 min; P < 0.0001; 60 Vs. 84 min at weekends, resp. 75 min at nights; P < 0.0001). Reperfusion therapy was performed in 72.8% (8,248/11,332) patients, and there were less patients treated on weekend versus "on"-hours (69.7 Vs. 77 %, P < 0.0001). On weekends we found a significant higher in-hospital mortality (11.1 Vs. 9.4%, P = 0.01) and at night there was a trend to higher in-hospital mortality when compared with regular working hours (10.6 Vs. 9.4%, P = 0.07). CONCLUSION In patients with STEMI admitted to hospitals with catheterization facilities, admission during the "off"-hours is associated with higher in-hospital mortality. This may be due to lower rates of revascularization therapy and longer prehospital and in-hospital delays as compared to "on"-hours.
