Role of a rapid response system and code status discussion as determinants of prognosis for critical inpatients: An observational study in a Japanese urban hospital.

ABSTRACT: Rapid response systems (RRS) have been introduced worldwide to reduce unpredicted in-hospital cardiac arrest (IHCA) and in-hospital mortality. The role of advance care planning (ACP) in the management of critical patients has not yet been fully determined in Japan.We retrospectively assessed the characteristics of all inpatients with unpredicted IHCA in our hospital between 2016 and 2018. Yearly changes in the number of RRS activations and the incidence of unpredicted IHCA with or without code status discussion were evaluated from 2014 to 2018. Hospital standardized mortality ratios were assessed from the data reported in the annual reports by the National Hospital Organization.A total of 81 patients (age: 70.9 ±â€Š13.3 years) suffered an unpredicted IHCA and had multiple background diseases, including heart disease (75.3%), chronic kidney disease (25.9%), and postoperative status (cardiovascular surgery, 18.5%). Most of the patients manifested non-shockable rhythms (69.1%); survival to hospital discharge rate was markedly lower than that with shockable rhythms (26.8% vs 72.0%, P < .001). The hospital standardized mortality ratios was maintained nearly constant at approximately 50.0% for 3 consecutive years. The number of cases of RRS activation markedly increased from 75 in 2014 to 274 patients in 2018; conversely, the number of unpredicted IHCA cases was reduced from 40 in 2014 to 18 in 2018 (P < .001). Considering the data obtained in 2014 and 2015 as references, the RRS led to a reduction in the relative risk of unpredicted IHCA from 2016 to 2018 (ie, 0.618, 95% confidence interval 0.453-0.843). The reduction in unpredicted IHCA was attributed partly to the increased number of patients who had discussed the code status, and a significant correlation was observed between these parameters (R2 = 0.992, P < .001). The reduction in the number of patients with end-stage disease, including congestive heart failure and chronic renal failure, paralleled the incidence of unpredicted IHCA.Both RRS and ACP reduced the incidence of unpredicted IHCA; RRS prevents progression to unpredicted IHCA, whereas ACP decreases the number of patients with no code status discussion and thus potentially reducing the patient subgroup progressing to an unpredicted IHCA.

Changes in trends during the COVID-19 lockdown: An urban, Level-1 trauma center's experience.

BACKGROUND: A community lockdown has a profound impact on its citizens. Our objective was to identify changes in trauma patient demographics, volume, and pattern of injury following the COVID-19 lockdown. METHODS: A retrospective review was conducted at a Level-1 Trauma Center from 2017 to 2020. RESULTS: A downward trend in volume is seen December-April in 2020 (R2 = 0.9907). February through April showed an upward trend in 2018 and 2019 (R2= 0.80 and R2 = 0.90 respectively), but a downward trend in 2020 (R2 = 0.97). In April 2020, there was 41.6% decrease in total volume, a 47.4% decrease in blunt injury and no decrease in penetrating injury. In contrast to previous months, in April the majority of injuries occurred in home zip codes. CONCLUSIONS: A community lockdown decreased the number of blunt trauma, however despite social distancing, did not decrease penetrating injury. Injuries were more likely to occur in home zip codes.

A Roadmap to Reopening a Neurosurgical Practice in the Age of COVID-19.

BACKGROUND: The Coronavirus disease 2019 (COVID-19) outbreak has left a lasting mark on medicine globally. METHODS: Here we outline the steps that the Lenox Hill Hospital/Northwell Health Neurosurgery Department-located within the epicenter of the pandemic in New York City-is currently taking to recover our neurosurgical efforts in the age of COVID-19. RESULTS: We outline measurable milestones to identify the transition to the recovery period and hope these recommendations may serve as a framework for an effective path forward. CONCLUSIONS: We believe that recovery following the COVID-19 pandemic offers unique opportunities to disrupt and rebuild the historical patient and office experience as we evolve with modern medicine in a post-COVID-19 world.

Statewide Longitudinal Progression of the Whole-Patient Measure of Safety in South Carolina.

Meaningful improvement in patient safety encompasses a vast number of quality metrics, but a single measure to represent the overall level of safety is challenging to produce. Recently, Perla et al. established the Whole-Person Measure of Safety (WPMoS) to reflect the concept of global risk assessment at the patient level. We evaluated the WPMoS across an entire state to understand the impact of urban/rural setting, academic status, and hospital size on patient safety outcomes. The population included all South Carolina (SC) inpatient discharges from January 1, 2008, through to December 31, 2013, and was evaluated using established definitions of highly undesirable events (HUEs). Over the study period, the proportion of hospital discharges with at least one HUE significantly decreased from 9.7% to 8.8%, including significant reductions in nine of the 14 HUEs. Academic, large, and urban hospitals had a significantly lower proportion of hospital discharges with at least one HUE in 2008, but only urban hospitals remained significantly lower by 2013. Results indicate that there has been a decrease in harm events captured through administrative coded data over this 6-year period. A composite measure, such as the WPMoS, is necessary for hospitals to evaluate their progress toward reducing preventable harm.

Single Institution Early Experience with the Bundled Payments for Care Improvement Initiative.

The Centers for Medicare & Medicaid Services (CMS) implemented the Bundled Payments for Care Improvement (BPCI) initiative in 2011. Through BPCI, organizations enlisted into payment agreements that include both performance and financial accountability for episodes of care. To succeed, BPCI requires quality maintenance and care delivery at lower costs. This necessitates physicians and hospitals to merge interests. Orthopaedic surgeons must assume leadership roles in cost containment, surgical safety, and quality assurance to deliver cost-effective care. Because most orthopaedic surgeons practice independently and are not employed by hospitals, models of physician-hospital alignment (e.g., physician-hospital organizations) or contracted gainsharing arrangements between practices and hospitals may be necessary for successful bundled pricing. Under BPCI, hospitals, surgeons, or third parties share rewards but assume risks for the bundle.For patients, cost savings must be associated with maintenance or improvement in quality metrics. However, the definition of quality can vary, as can the rewards for processes and outcomes. Risk stratification for potential complications should be considered in bundled pricing agreements to prevent the exclusion of patients with substantial comorbidities and higher care costs (e.g., hip fractures treated with prostheses). Bundled pricing depends on economies of scale for success; smaller institutions must be cautious, as 1 costly patient could substantially impact the finances of its entire program. CMS recommends a minimum of 100 to 200 cases yearly. We also suggest that participants utilize technologies to maximize efficiency and provide the best possible environment for implementation of bundled payments. Substantial investment in infrastructure is required to develop programs to improve coordination of care, manage quality data, and distribute payments. Smaller institutions may have difficulty devoting resources to these infrastructural changes, although changes may be implemented more thoroughly once initiated. Herein, we discuss our early total joint arthroplasty BPCI experience at our tertiary-care academic medical center.

Impact of Stewardship Interventions on Antiretroviral Medication Errors in an Urban Medical Center: A 3-Year, Multiphase Study.

BACKGROUND: There is a high prevalence of HIV infection in Newark, New Jersey, with University Hospital admitting approximately 600 HIV-infected patients per year. Medication errors involving antiretroviral therapy (ART) could significantly affect treatment outcomes. The goal of this study was to evaluate the effectiveness of various stewardship interventions in reducing the prevalence of prescribing errors involving ART. METHODS: This was a retrospective review of all inpatients receiving ART for HIV treatment during three distinct 6-month intervals over a 3-year period. During the first year, the baseline prevalence of medication errors was determined. During the second year, physician and pharmacist education was provided, and a computerized order entry system with drug information resources and prescribing recommendations was implemented. Prospective audit of ART orders with feedback was conducted in the third year. Analyses and comparisons were made across the three phases of this study. RESULTS: Of the 334 patients with HIV admitted in the first year, 45% had at least one antiretroviral medication error and 38% had uncorrected errors at the time of discharge. After education and computerized order entry, significant reductions in medication error rates were observed compared to baseline rates; 36% of 315 admissions had at least one error and 31% had uncorrected errors at discharge. While the prevalence of antiretroviral errors in year 3 was similar to that of year 2 (37% of 276 admissions), there was a significant decrease in the prevalence of uncorrected errors at discharge (12%) with the use of prospective review and intervention. CONCLUSIONS: Interventions, such as education and guideline development, can aid in reducing ART medication errors, but a committed stewardship program is necessary to elicit the greatest impact.

[An urban EMS at the start of a cross-sectoral quality management system: prioritized implementation of the 2010 ERC recommendations and long-term survival after cardiac arrest]. / Ein städtischer Rettungsdienstbereich am Beginn eines sektorenübergreifenden Qualitätsmanagementsystems: Eine priorisierte Umsetzung der ERC Empfehlungen von 2010 und das Langzeitüberleben nach Herzkreislaufstillstand.

INTRODUCTION: Due to limited resources, the 2010 European Resuscitation Council (ERC) guidelines could not be fully implemented in the Emergency Medical Services (EMS) of Brunswick, Germany. This is why implementation was prioritized according to local conditions. Thus, prehospital therapeutic hypothermia, mechanical chest compression and feedback systems were not established. Clinical data and long-term results were assessed by a QM system and room for improvement was identified. METHODS: All attempted resuscitations from 2011 until 2014 were recorded and compared against the German Resuscitation Registry. Outcomes of adult patients following non-traumatic cardiac arrest were analyzed by year. RESULTS: 812 resuscitations were attempted (incidence 81.2/100,000 inhabitants/year). In the two years following full implementation since 2013 the discharge rate from hospital was 16.4 %, the discharge rate with a favorable neurologic outcome was 14.1 %, the 1-year survival rate was 14.4 % in 2013. A significant improvement of risk-adjusted ROSC rate during the investigation period was demonstrated. The discharge rates remained unchanged; the increase in the discharge rates paralleled the increase in CPR incidence. EMS response times were remarkably shorter. CONCLUSION: The implementation of the ERC guidelines chosen appears to be generally safe. Fast EMS response contributed to superior results. All links of the chain of survival showed room for improvement, especially the proportion of lay rescuer CPR and telephone-assisted CPR. The high CPR incidence might indicate room for improvement in prevention. Access to resuscitation care can hardly be evaluated. Age-related access to pre-hospital resuscitation seems to be appropriate.

Impact of accreditation in bariatric surgery.

BACKGROUND: Several studies have shown improved outcomes associated with accredited bariatric centers. The aim of our study was to examine the outcomes of bariatric surgery performed at accredited versus nonaccredited centers using a nationally representative database. Additionally, we aimed to determine if the presence of bariatric surgery accreditation could lead to improved outcomes for morbidly obese patients undergoing other general laparoscopic operations. METHODS: Using the Nationwide Inpatient Sample database, for data between 2008 and 2010, clinical data of morbidly obese patients who underwent bariatric surgery, laparoscopic antireflux surgery, cholecystectomy, and colectomy were analyzed according to the hospital's bariatric accreditation status. RESULTS: A total of 277,068 bariatric operations were performed during the 3-year period, with 88.4% of cases performed at accredited centers. In-hospital mortality was significantly lower at accredited compared to nonaccredited centers (.08% versus .19%, respectively). Multivariate analysis showed that nonaccredited centers had higher risk-adjusted mortality for bariatric procedures compared to accredited centers (odds ratio [OR] 3.1, P<.01). Post hoc analysis showed improved mortality for patients who underwent gastric bypass and sleeve gastrectomy at accredited centers compared to nonaccredited centers (.09% versus .27%, respectively, P<.01). Patients with a high severity of illness who underwent bariatric surgery also had lower mortality rates when the surgery was performed at accredited versus nonaccredited centers (.17% versus .45%, respectively, P<.01). Multivariate analysis showed that morbidly obese patients who underwent laparoscopic cholecystectomy (OR 2.4, P<.05) and antireflux surgery (OR 2.03, P<.01) at nonaccredited centers had higher rates of serious complications. CONCLUSION: Accreditation in bariatric surgery was associated with more than a 3-fold reduction in risk-adjusted in-hospital mortality. Resources established for bariatric surgery accreditation may have the secondary benefit of improving outcomes for morbidly obese patients undergoing general laparoscopic operations.

Practice and documentation of performance of colonoscopy in a central Canadian health region.

OBJECTIVE: To evaluate the reporting and performance of colonoscopy in a large urban centre. METHODS: Colonoscopies performed between January and April 2008 in community hospitals and academic centres in the Winnipeg Regional Health Authority (Manitoba) were identified from hospital discharge databases and retrospective review of a random sample of identified charts. Information regarding reporting of colonoscopies (including bowel preparation, photodocumentation of cecum/ileum, size, site, characteristics and method of polyp removal), colonoscopy completion rates and follow-up recommendations was extracted. Colonoscopy completion rates were compared among different groups of physicians. RESULTS: A total of 797 colonoscopies were evaluated. Several deficiencies in reporting were identified. For example, bowel preparation quality was reported in only 20%, the agent used for bowel preparation was recorded in 50%, photodocumentation of colonoscopy completion in 6% and polyp appearance (ie, pedunculated or not) in 34%, and polyp size in 66%. Although the overall colonoscopy completion rate was 92%, there was a significant difference among physicians with varying medical specialty training and volume of procedures performed. Recommendations for follow-up procedures (barium enema, computed tomography colonography or repeat colonoscopy) were recorded for a minority of individuals with reported poor bowel preparation or incomplete colonoscopy. CONCLUSIONS: The present study found many deficiencies in reporting of colonoscopy in typical, city-wide clinical practices. Colonoscopy completion rates varied among different physician specialties. There is an urgent need to adopt standardized colonoscopy reporting systems in everyday practice and to provide feedback to physicians regarding deficiencies so they can be rectified.

Utility of a child abuse screening guideline in an urban pediatric emergency department.

BACKGROUND: Previous studies have found racial and socioeconomic status bias in the way clinicians screen for and detect child abuse in patients presenting to the emergency department. We hypothesized that implementing a guideline for screening would attenuate this bias. METHODS: An algorithm for child abuse screening in patients younger than 1 year presenting with fractures was developed for a pediatric trauma center emergency department. Data were collected 1.5 years before and after implementation of the algorithm to investigate implementation success. Data were compared before and after the implementation of the algorithm using χ and univariate logistic regression analysis. RESULTS: The characteristics of patients with fractures were similar before and after the algorithm implementation. Implementation of the algorithm was related to a significant increase in algorithm required screenings: skeletal survey (p < 0.001), urinalysis (p < 0.001), and transaminase levels (p < 0.001). The racial composition of those screened did not change after the implementation of the protocol. Children with government-subsidized or no insurance were more likely to be screened for child abuse via skeletal survey before the algorithm implementation compared with those with private insurance (odds ratio, 2.7; 95% confidence interval, 1.2-6.0; p = 0.017). This relationship did not exist after the algorithm implementation (odds ratio, 1.2; 95% confidence interval, 0.56-2.46; p = 0.66). Final determination of child abuse was related to insurance status both before and after the algorithm implementation. CONCLUSION: A child abuse screening algorithm was successfully implemented in an urban trauma center. After implementation, screening was no longer associated with socioeconomic status of the patient's family, although final determination of child abuse still was. Additional research is needed to determine utility of unbiased screening on patient outcomes. LEVEL OF EVIDENCE: Therapeutic study, level IV.

Investigating the congruence of crowdsourced information with official government data: the case of pediatric clinics.

BACKGROUND: Health 2.0 is a benefit to society by helping patients acquire knowledge about health care by harnessing collective intelligence. However, any misleading information can directly affect patients' choices of hospitals and drugs, and potentially exacerbate their health condition. OBJECTIVE: This study investigates the congruence between crowdsourced information and official government data in the health care domain and identifies the determinants of low congruence where it exists. In-line with infodemiology, we suggest measures to help the patients in the regions vulnerable to inaccurate health information. METHODS: We text-mined multiple online health communities in South Korea to construct the data for crowdsourced information on public health services (173,748 messages). Kendall tau and Spearman rank order correlation coefficients were used to compute the differences in 2 ranking systems of health care quality: actual government evaluations of 779 hospitals and mining results of geospecific online health communities. Then we estimated the effect of sociodemographic characteristics on the level of congruence by using an ordinary least squares regression. RESULTS: The regression results indicated that the standard deviation of married women's education (P=.046), population density (P=.01), number of doctors per pediatric clinic (P=.048), and birthrate (P=.002) have a significant effect on the congruence of crowdsourced data (adjusted R²=.33). Specifically, (1) the higher the birthrate in a given region, (2) the larger the variance in educational attainment, (3) the higher the population density, and (4) the greater the number of doctors per clinic, the more likely that crowdsourced information from online communities is congruent with official government data. CONCLUSIONS: To investigate the cause of the spread of misleading health information in the online world, we adopted a unique approach by associating mining results on hospitals from geospecific online health communities with the sociodemographic characteristics of corresponding regions. We found that the congruence of crowdsourced information on health care services varied across regions and that these variations could be explained by geospecific demographic factors. This finding can be helpful to governments in reducing the potential risk of misleading online information and the accompanying safety issues.

Rural-urban differences in inpatient quality of care in US Veterans with ischemic stroke.

PURPOSE: Differences in stroke care quality for patients in rural and urban locations have been suggested, but whether differences exist across Veteran Administration Medical Centers (VAMCs) is unknown. This study examines whether rural-urban disparities exist in inpatient quality among veterans with acute ischemic stroke. METHODS: In this retrospective study, inpatient stroke care quality was assessed in a national sample of veterans with acute ischemic stroke using 14 quality indicators (QIs). Rural-Urban Commuting Areas codes defined each VAMC's rural-urban status. A hierarchical linear model assessed the rural-urban differences across the 14 QIs, adjusting for patient and facility characteristics, and clustering within VAMCs. FINDINGS: Among 128 VAMCs, 18 (14.1%) were classified as rural VAMCs and admitted 284 (7.3%) of the 3,889 ischemic stroke patients. Rural VAMCs had statistically significantly lower unadjusted rates on 6 QIs: Deep vein thrombosis (DVT) prophylaxis, antithrombotic at discharge, antithrombotic at day 2, lipid management, smoking cessation counseling, and National Institutes of Health Stroke Scale completion, but they had higher rates of stroke education, functional assessment, and fall risk assessment. After adjustment, differences in 2 QIs remained significant-patients treated in rural VAMCs were less likely to receive DVT prophylaxis, but more likely to have documented functional assessment. CONCLUSIONS: After adjustment for key demographic, clinical, and facility-level characteristics, there does not appear to be a systematic difference in inpatient stroke quality between rural and urban VAMCs. Future research should seek to understand the few differences in care found that could serve as targets for future quality improvement interventions.

The assessment of stat laboratory test ordering practice and impact of targeted individual feedback in an urban teaching hospital.

BACKGROUND: Overuse of inpatient stat laboratory orders ("stat" is an abbreviation of the Latin word "statim," meaning immediately, without delay) is a major problem in the modern healthcare system. OBJECTIVE: To understand patterns of stat laboratory ordering practices at our institution and to assess the effectiveness of individual feedback in reducing these orders. INTERVENTION: Medicine and General Surgery residents were given a teaching session about appropriate stat ordering practice in January 2010. Individual feedback was given to providers who were the highest utilizers of stat laboratory orders by their direct supervisors from February through June of 2010. MEASUREMENTS: The proportion of stat orders out of total laboratory orders per provider was the main outcome measure. All inpatient laboratory orders from September 2009 to June 2010 were analyzed. RESULTS: The median proportion of stat orders out of total laboratory orders was 41.6% for nontrainee providers (N = 500), 38.7% for Medicine residents (N = 125), 80.2% for General Surgery residents (N = 32), and 24.2% for other trainee providers (N = 150). Among 27 providers who received feedback (7 nontrainees, 16 Medicine residents, and 4 General Surgery residents), the proportion of stat laboratory orders per provider decreased by 15.7% (95% confidence interval: 5.6%-25.9%, P = 0.004) after feedback, whereas the decrease among providers who were high utilizers but did not receive feedback (N = 39) was not significant (4.5%; 95% confidence interval: 2.1%-11.0%, P = 0.18). Monthly trends showed reduction in the proportion of stat orders among Medicine and General Surgery residents, but not among other trainee providers. CONCLUSIONS: The frequency of stat ordering was highly variable among providers. Individual feedback to the highest utilizers of stat orders was effective in decreasing these orders.

Patterns of early mortality after trauma in a neighborhood urban trauma center: can we improve outcomes?

Even with specialized trauma systems, a significant number of deaths occur within the early postinjury period. Our goal was to examine deaths within this period for cause and determine if care could improve outcomes. A retrospective chart review was performed on all patients who were dead on arrival or died within 4 hours of arrival between January 1, 2005, and December 31, 2011. Survival probabilities and Injury Severity Score (ISS) were calculated. Chart review and trauma review processes were used to determine cases with opportunities for care improvement. Two hundred eighty-nine patients were dead on arrival (DOA), and 176 patients died within 4 hours of arrival. The most common mechanism of injury was gunshot wounds (68.4%). The most common causes of death were uncontrolled hemorrhage (68.2%) and neurologic trauma (23.4%). Average ISS was 32. Twenty-nine patients had survival probability percentages over 50. Ten of 176 (5.7%) deaths were found to have opportunities for care improvement. In three cases (1.7%), errors contributed to death. The majority of trauma patients DOA or dying within 4 hours of hospital arrival have nonsurvivable injuries. Regular trauma review processes are invaluable in determining opportunities for care improvement. Autopsy information increases the reliability of the review process.

Impact of Society of Cardiovascular Patient Care accreditation on quality: an ACTION Registry®-Get With The Guidelines™ analysis.

BACKGROUND: The Society of Cardiovascular Patient Care (SCPC) accredits hospital acute coronary syndrome management. The influence of accreditation on the subset of patients diagnosed with acute myocardial infarction (AMI) is unknown. Our purpose was to describe the association between SCPC accreditation and hospital quality metric performance among AMI patients enrolled in ACTION Registry-GWTG (ACTION-GWTG). This program is a voluntary registry that receives self-reported hospital AMI quality metrics data and provides quarterly feedback to 487 US hospitals. METHODS: Using urban nonacademic hospital registry data from January 1, 2007, to June 30, 2010, we performed a 1 to 2 matched pairs analysis, selecting 14 of 733 (1.9%) SCPC accredited and 28 of 309 (9.1%) nonaccredited registry facilities to compare changes in quality metrics between the year before and after SCPC accreditation. RESULTS: All hospitals improved quality metric compliance during the study period. Nonaccredited hospitals started with slightly lower rates of AMI composite score 1 year before accreditation. Although improvement compared with baseline was greater for nonaccredited hospitals (odds ratio = 1.27; 95% confidence interval: 1.20, 1.35) than accredited hospitals (odds ratio = 1.15; 95% confidence interval: 1.07, 1.23) (P = 0.022), the group ended with similar compliance scores (92.1% vs. 92.2%, respectively). Improvements in evaluating left ventricular function (P = 0.0001), adult smoking cessation advice (P = 0.0063), and cardiac rehab referral (P = 0.0020) were greater among nonaccredited hospitals, whereas accredited hospitals had greater improvement in discharge angiotensin-converting-enzyme inhibitor or angiotensin II receptor blocker use for left ventricular systolic dysfunction (P = 0.0238). CONCLUSIONS: All hospitals had high rates of quality metric compliance and finished with similar overall AMI performance composite scores after 1 year.

Clinical practice guidelines for pediatric appendicitis evaluation can decrease computed tomography utilization while maintaining diagnostic accuracy.

OBJECTIVES: The objective of this study was to compare usage of computed tomography (CT) scan for evaluation of appendicitis in a children's hospital emergency department before and after implementation of a clinical practice guideline focused on early surgical consultation before obtaining advanced imaging. METHODS: A multidisciplinary team met to create a pathway to formalize the evaluation of pediatric patients with abdominal pain. Computed tomography scan utilization rates were studied before and after pathway implementation. RESULTS: Among patients who had appendectomy in the year before implementation (n = 70), 90% had CT scans, 6.9% had ultrasound, and 5.7% had no imaging. The negative appendectomy rate before implementation was 5.7%. In patients undergoing appendectomy in the postimplementation cohort (n = 96), 48% underwent CT, 39.6% underwent ultrasound, and 15.6% had no imaging. The negative appendectomy rate was 5.2%. We demonstrated a 41% decrease in CT use for patients undergoing appendectomy at our institution without an increase in the negative appendectomy rate or missed appendectomy. The results were even more striking when comparing the rate of CT scan use in the subset of patients undergoing appendectomy without imaging from an outside hospital. In these patients, CT scan utilization decreased from 82% to 20%, a 76% reduction in CT use in our facility after protocol implementation. CONCLUSIONS: Implementation of a clinical evaluation pathway emphasizing examination, early surgeon involvement, and utilization of ultrasound as the initial imaging modality for evaluation of abdominal pain concerning for appendicitis resulted in a marked decrease in the reliance on CT scanning without loss of diagnostic accuracy.

Air quality monitoring of the post-operative recovery room and locations surrounding operating theaters in a medical center in Taiwan.

To prevent surgical site infection (SSI), the airborne microbial concentration in operating theaters must be reduced. The air quality in operating theaters and nearby areas is also important to healthcare workers. Therefore, this study assessed air quality in the post-operative recovery room, locations surrounding the operating theater area, and operating theaters in a medical center. Temperature, relative humidity (RH), and carbon dioxide (CO2), suspended particulate matter (PM), and bacterial concentrations were monitored weekly over one year. Measurement results reveal clear differences in air quality in different operating theater areas. The post-operative recovery room had significantly higher CO2 and bacterial concentrations than other locations. Bacillus spp., Micrococcus spp., and Staphylococcus spp. bacteria often existed in the operating theater area. Furthermore, Acinetobacter spp. was the main pathogen in the post-operative recovery room (18%) and traumatic surgery room (8%). The mixed effect models reveal a strong correlation between number of people in a space and high CO2 concentration after adjusting for sampling locations. In conclusion, air quality in the post-operative recovery room and operating theaters warrants attention, and merits long-term surveillance to protect both surgical patients and healthcare workers.

An observational study of the frequency, severity, and etiology of failures in postoperative care after major elective general surgery.

OBJECTIVE: To investigate the nature of process failures in postoperative care, to assess their frequency and preventability, and to explore their relationship to adverse events. BACKGROUND: Adverse events are common and are frequently caused by failures in the process of care. These processes are often evaluated independently using clinical audit. There is little understanding of process failures in terms of their overall frequency, relative risk, and cumulative effect on the surgical patient. METHODS: Patients were observed daily from the first postoperative day until discharge by an independent surgeon. Field notes on the circumstances surrounding any nonroutine or atypical event were recorded. Field notes were assessed by 2 surgeons to identify failures in the process of care. Preventability, the degree of harm caused to the patient, and the underlying etiology of process failures were evaluated by 2 independent surgeons. RESULTS: Fifty patients undergoing major elective general surgery were observed for a total of 659 days of postoperative care. A total of 256 process failures were identified, of which 85% were preventable and 51% directly led to patient harm. Process failures occurred in all aspects of care, the most frequent being medication prescribing and administration, management of lines, tubes, and drains, and pain control interventions. Process failures accounted for 57% of all preventable adverse events. Communication failures and delays were the main etiologies, leading to 54% of process failures. CONCLUSIONS: Process failures are common in postoperative care, are highly preventable, and frequently cause harm to patients. Interventions to prevent process failures will improve the reliability of surgical postoperative care and have the potential to reduce hospital stay.
