Use of failure-to-rescue to identify international variation in postoperative care in low-, middle- and high-income countries: a 7-day cohort study of elective surgery

Family supplemented patient monitoring after surgery (SMARTER): a pilot stepped-wedge cluster-randomised trial

BACKGROUND

Mortality after surgery in Africa is twice that in high-income countries. Most deaths occur on wards after patients develop postoperative complications. Family members might contribute meaningfully and safely to early recognition of deteriorating patients.

METHODS

This was a stepped-wedge cluster-randomised trial of an intervention training family members to support nursing staff to take and record patient vital signs every 4 h after surgery. Adult inpatients across four surgical wards (clusters) in a Ugandan hospital were included. Clusters crossed once from routine care to the SMARTER intervention at monthly intervals. The primary outcome was frequency of vital sign measurements from arrival on the postoperative ward to the end of the third postoperative day (3 days).

RESULTS

We enrolled 1395 patients between April and October 2021. Mean age was 28.2 (range 5-89) yr; 85.7% were female. The most common surgical procedure was Caesarean delivery (74.8%). Median (interquartile range) number of sets of vital signs increased from 0 (0-1) in control wards to 3 (1-8) in intervention wards (incident rate ratio 12.4, 95% confidence interval [CI] 8.8-17.5, P<0.001). Mortality was 6/718 (0.84%) patients in the usual care group vs 12/677 (1.77%) in the intervention group (odds ratio 1.32, 95% CI 0.1-14.7, P=0.821). There was no difference in length of hospital stay between groups (usual care: 2 [2-3] days vs intervention: 2 [2-4] days; hazard ratio 1.11, 95% CI 0.84-1.47, P=0.44).

CONCLUSIONS

Family member supplemented vital signs monitoring substantially increased the frequency of vital signs after surgery. Care interventions involving family members have the potential to positively impact patient care.

The frailty-driven predictive model for failure to rescue among patients who experienced a major complication following cervical decompression and fusion: an ACS-NSQIP analysis of 3,632 cases (2011-2020)

BACKGROUND CONTEXT

Preoperative risk stratification for patients considering cervical decompression and fusion (CDF) relies on established independent risk factors to predict the probability of complications and outcomes in order to help guide pre and perioperative decision-making.

PURPOSE

This study aims to determine frailty's impact on failure to rescue (FTR), or when a mortality occurs within 30 days following a major complication.

STUDY DESIGN/SETTING

Cross-sectional retrospective analysis of retrospective and nationally-representative data.

PATIENT SAMPLE

The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was queried for all CDF cases from 2011-2020.

OUTCOME MEASURES

CDF patients who experienced a major complication were identified and FTR was calculated as death or hospice disposition within 30 days of a major complication.

METHODS

Frailty was measured by the Risk Analysis Index-Revised (RAI-Rev). Baseline patient demographics and characteristics were compared for all FTR patients. Significant factors were assessed by univariate and multivariable regression for the development of a frailty-driven predictive model for FTR. The discriminative ability of the predictive model was assessed using a receiving operating characteristic (ROC) curve analysis.

RESULTS

There were 3632 CDF patients who suffered a major complication and 7.6% (277 patients) subsequently expired or dispositioned to hospice, the definition of FTR. Independent predictors of FTR were nonelective surgery, frailty, preoperative intubation, thrombosis or embolic complication, unplanned intubation, on ventilator for >48 hours, cardiac arrest, and septic shock. Frailty, and a combination of preoperative and postoperative risk factors in a predictive model for FTR, achieved outstanding discriminatory accuracy (C-statistic = 0.901, CI: 0.883-0.919).

CONCLUSION

Preoperative and postoperative risk factors, combined with frailty, yield a highly accurate predictive model for FTR in CDF patients. Our model may guide surgical management and/or prognostication regarding the likelihood of FTR after a major complication postoperatively with CDF patients. Future studies may determine the predictive ability of this model in other neurosurgical patient populations.

Intensive care utilisation after elective surgery in Australia and New Zealand: A point prevalence study

Objective

We aimed to describe the characteristics, outcomes and resource utilisation of patients being cared for in an ICU after undergoing elective surgery in Australia and New Zealand (ANZ).

Methods

This was a point prevalence study involving 51 adult ICUs in ANZ in June 2021. Patients met inclusion criteria if they were being treated in a participating ICU on he study dates. Patients were categorised according to whether they had undergone elective surgery, admitted directly from theatre or unplanned from the ward. Descriptive and comparative analysis was performed according to the source of ICU admission. Resource utilisation was measured by Length of stay, organ support and occupied bed days.

Results

712 patients met inclusion criteria, with 172 (24%) have undergone elective surgery. Of these, 136 (19%) were admitted directly to the ICU and 36 (5.1%) were an unplanned admission from the ward. Elective surgical patients occupied 15.8% of the total ICU patient bed days, of which 44.3% were following unplanned admissions. Elective surgical patients who were an unplanned admission from the ward, compared to those admitted directly from theatre, had a higher severity of illness (AP2 17 vs 13, p<0.01), require respiratory or vasopressor support (75% vs 44%, p<0.01) and hospital mortality (16.7% vs 2.2%, p < 0.01).

Conclusions

ICU resource utilisation of patients who have undergone elective surgery is substantial. Those patients admitted directly from theatre have good outcomes and low resource utilisation. Patient admitted unplanned from the ward, although fewer, were sicker, more resource intensive and had significantly worse outcomes.

Pancreatic surgery outcomes: multicentre prospective snapshot study in 67 countries

BACKGROUND

Pancreatic surgery remains associated with high morbidity rates. Although postoperative mortality appears to have improved with specialization, the outcomes reported in the literature reflect the activity of highly specialized centres. The aim of this study was to evaluate the outcomes following pancreatic surgery worldwide.

METHODS

This was an international, prospective, multicentre, cross-sectional snapshot study of consecutive patients undergoing pancreatic operations worldwide in a 3-month interval in 2021. The primary outcome was postoperative mortality within 90 days of surgery. Multivariable logistic regression was used to explore relationships with Human Development Index (HDI) and other parameters.

RESULTS

A total of 4223 patients from 67 countries were analysed. A complication of any severity was detected in 68.7 per cent of patients (2901 of 4223). Major complication rates (Clavien-Dindo grade at least IIIa) were 24, 18, and 27 per cent, and mortality rates were 10, 5, and 5 per cent in low-to-middle-, high-, and very high-HDI countries respectively. The 90-day postoperative mortality rate was 5.4 per cent (229 of 4223) overall, but was significantly higher in the low-to-middle-HDI group (adjusted OR 2.88, 95 per cent c.i. 1.80 to 4.48). The overall failure-to-rescue rate was 21 per cent; however, it was 41 per cent in low-to-middle- compared with 19 per cent in very high-HDI countries.

CONCLUSION

Excess mortality in low-to-middle-HDI countries could be attributable to failure to rescue of patients from severe complications. The authors call for a collaborative response from international and regional associations of pancreatic surgeons to address management related to death from postoperative complications to tackle the global disparities in the outcomes of pancreatic surgery (NCT04652271; ISRCTN95140761).

Intensive care utilisation after elective surgery in Australia and New Zealand: getting the balance right

Of the total intensive care unit (ICU) admissions in Australia and New Zealand, 36.6% occur following an elective surgical procedure. How best to use ICU services in this setting is not clear, despite this being an expensive and resource-intensive method of care delivery. The literature relating to this area has not demonstrated a clear association between improved outcomes and routine ICU utilisation. It has, however, demonstrated that methods of care delivery in this setting vary at the local, national and international level. There is now an increased interest in how we can offer safe, efficient care to patients who need ICU-level support after elective surgery, as well as where and when that care can be offered. We had previously performed a literature review relating to ICU utilisation in the elective surgical post-operative setting. This perspective piece arises from this literature review as well as extensive clinical experience from the authors. We discuss the need for a move towards an evidence-based indication for ICU admission and how this may be achieved. We then move on to the various alternative models of care that could be offered, briefly discussing their positives and potential drawbacks. We finish by outlining the research priorities and how these might be implemented in clinical practice. Getting the balance right between ICU admission and higher acuity ward-level care for post-operative elective surgical patients is difficult. However, this is an important challenge that we as a healthcare community must be working to answer.

Outcomes of elective liver surgery worldwide: a global, prospective, multicenter, cross-sectional study

BACKGROUND

The outcomes of liver surgery worldwide remain unknown. The true population-based outcomes are likely different to those vastly reported that reflect the activity of highly specialized academic centers. The aim of this study was to measure the true worldwide practice of liver surgery and associated outcomes by recruiting from centers across the globe. The geographic distribution of liver surgery activity and complexity was also evaluated to further understand variations in outcomes.

METHODS

LiverGroup.org was an international, prospective, multicenter, cross-sectional study following the Global Surgery Collaborative Snapshot Research approach with a 3-month prospective, consecutive patient enrollment within January-December 2019. Each patient was followed up for 90 days postoperatively. All patients undergoing liver surgery at their respective centers were eligible for study inclusion. Basic demographics, patient and operation characteristics were collected. Morbidity was recorded according to the Clavien-Dindo Classification of Surgical Complications. Country-based and hospital-based data were collected, including the Human Development Index (HDI). (NCT03768141).

RESULTS

A total of 2159 patients were included from six continents. Surgery was performed for cancer in 1785 (83%) patients. Of all patients, 912 (42%) experienced a postoperative complication of any severity, while the major complication rate was 16% (341/2159). The overall 90-day mortality rate after liver surgery was 3.8% (82/2,159). The overall failure to rescue rate was 11% (82/ 722) ranging from 5 to 35% among the higher and lower HDI groups, respectively.

CONCLUSIONS

This is the first to our knowledge global surgery study specifically designed and conducted for specialized liver surgery. The authors identified failure to rescue as a significant potentially modifiable factor for mortality after liver surgery, mostly related to lower Human Development Index countries. Members of the LiverGroup.org network could now work together to develop quality improvement collaboratives.

Initiatives to detect and prevent death from perioperative deterioration

PURPOSE OF REVIEW

This study indicates that there are differences between hospitals in detection, as well as in adequate management of postsurgical complications, a phenomenon that is described as 'failure-to-rescue'.In this review, recent initiatives to reduce failure-to-rescue in the perioperative period are described.

RECENT FINDINGS

Use of cognitive aids, emergency manuals, family participation as well as remote monitoring systems are measures to reduce failure-to-rescue situations. Postoperative visit of an anaesthesiologist on the ward was not shown to improve outcome, but there is still room for improvement of postoperative care.

SUMMARY

Improving the complete emergency chain, including monitoring, recognition and response in the afferent limb, as well as diagnostic and treatment in the efferent limb, should lead to reduced failure-to-rescue situations in the perioperative period.

Troponin elevation as a marker of short deterioration and one-year death in a high-risk surgical patient cohort in a low and middle income country setting: a postoperative approach to increase surveillance

PURPOSE

Myocardial injury after noncardiac surgery is common and mostly asymptomatic. The ideal target population that will benefit from routine troponin measurements in low and middle income countries (LMICs) is unclear. This study aims to evaluate the clinical outcomes of a cohort of high-risk surgical patients according to high-sensitivity troponin T (hsTnT) in an LMIC setting.

METHODS

We conducted a prospective cohort study of 442 high-risk patients undergoing noncardiac surgery at a Brazilian hospital between February 2019 and March 2020. High-sensitivity troponin T levels were measured preoperatively, 24 hr, and 48 hr after surgery and stratified into three groups: normal (< 20 ng·L-1); minor elevation (20-65 ng·L-1); and major elevation (> 65 ng·L-1). We performed survival analysis to determine the association between myocardial injury and one-year mortality. We described medical interventions and evaluated unplanned intensive care unit (ICU) admission and complications using multivariable models.

RESULTS

Postoperative myocardial injury occurred in 45% of patients. Overall, 30-day mortality was 8%. Thirty-day and one-year mortality were higher in patients with hsTnT ≥ 20 ng·L-1. One-year mortality was 18% in the unaltered troponin group vs 31% and 41% for minor and major elevation groups, respectively. Multivariable analysis of one-year survival showed a hazard ratio (HR) of 1.94 (95% confidence interval [CI], 1.22 to 3.09) for the minor elevation group and a HR of 2.73 (95% CI, 1.67 to 4.45) for the troponin > 65 ng·L-1 group. Patients with altered troponin had more unplanned ICU admissions (13% vs 5%) and more complications (78% vs 48%).

CONCLUSION

This study supports evidence that hsTnT is an important prognostic marker and a strong predictor of all-cause mortality after surgery. Troponin measurement in high-risk surgical patients could potentially be used as tool to scale-up care in LMIC settings.

Perioperative optimisation in low- and middle-income countries (LMICs): A systematic review and meta-analysis of enhanced recovery after surgery (ERAS)

Background

Enhanced recovery after surgery (ERAS) protocols have largely been incorporated into practice in high-income settings due to proven improvement in perioperative outcomes. We aimed to review the implementation of ERAS protocols and other perioperative optimisation strategies in low- and middle-income countries (LMICs) and their impact on length of hospital stay (LOS).

Methods

We searched MEDLINE, PubMed, Global Health (CABI), WHO Global Index Medicus, Index Medicus, and Latin American and Caribbean Health Sciences Literature (LILACS) for studies incorporating ERAS or other prehabilitation approaches in LMICs. We conducted a pooled analysis of LOS using a random-effects model to evaluate the impact of such programs. This systematic review was pre-registered on PROSPERO.

Results

We screened 1205 studies and included 70 for a full-text review; six were eligible for inclusion and five for quantitative analysis, two of which were randomised controlled trials. ERAS was compared to routine practice in all included studies, while none implemented prehabilitation or other preoperative optimisation strategies. Pooled analysis of 290 patients showed reduced LOS in the ERAS group with a standardised mean difference of -2.18 (95% confidence interval (CI) = -4.13, -.0.05, P < 0.01). The prediction interval was wide (95% CI = -7.85, 3.48) with substantial heterogeneity (I2 = 94%).

Conclusions

Perioperative optimisation is feasible in LMICs and appears to reduce LOS, despite high levels of between-study heterogeneity. There is a need for high-quality data on perioperative practice in LMICs and supplementary qualitative analysis to further understand barriers to perioperative optimisation implementation.

Failure to Rescue in Major Abdominal Surgery: A Regional Australian Experience

BACKGROUND

Failure to rescue (FTR) is increasingly recognised as a measure of the quality care provided by a health service in recognising and responding to patient deterioration. We report the association between a patient's pre-operative status and FTR following major abdominal surgery.

METHODS

A retrospective chart review was conducted on patients who underwent major abdominal surgery and who suffered Clavien-Dindo (CDC) III-V complications at the University Hospital Geelong between 2012 and 2019. For each patient suffering a major complication, pre-operative risk factors including demographics, comorbidities (Charlson Comorbidity Index (CCI)), American Society of Anaesthesiology (ASA) Score and biochemistry were compared for patients who survived and patients who died. Statistical analysis utilised logistic regression with results reported as odds ratios (ORs) and 95% confidence intervals (CIs).

RESULTS

There were 2579 patients who underwent major abdominal surgery, of whom 374 (14.5%) suffered CDC III-V complications. Eighty-eight patients subsequently died from their complication representing a 23.5% FTR and an overall operative mortality of 3.4%. Pre-operative risk factors for FTR included ASA score ≥ 3, CCI ≥ 3 and pre-operative serum albumin of < 35 g/L. Operative risk factors included emergency surgery, cancer surgery, greater than 500 ml intraoperative blood loss and need for ICU admission. Patients who suffered end-organ failure were more likely to die from their complication.

CONCLUSION

Identification of patients at high risk of FTR should they develop a complication would inform shared decision-making, highlight the need for optimisation prior to surgery, or in some cases, result in surgery not being undertaken.

Failure to Rescue and Mortality Differences After Appendectomy in a Low-Middle-Income Country and the United States

BACKGROUND

Major disparities in complications and mortality after appendectomy between countries with different income levels have not been well characterized, as comparative studies at patient level between countries are scant. This study aimed to investigate variations in postoperative complications, mortality, and failure to rescue after appendectomy between a high-income country and a low-to-middle-income country.

METHODS

Hospital discharges on adult patients who underwent appendectomy were extracted from administrative databases from Colombia and 2 states of the United States (Florida and New York). Outcomes included major postoperative complications, in-hospital mortality, and failure to rescue. Univariate analyses were conducted to compare outcomes between the 2 countries. Multivariable logistic regression analyses were conducted to examine the independent effect of country on outcomes after adjustment for patient age, sex, comorbidity index, severity of appendicitis, and appendectomy route (laparoscopic/open).

RESULTS

A total of 62,338 cases from Colombia and 57,987 from the United States were included in the analysis. Patients in Colombia were significantly younger and healthier but had a higher incidence of peritonitis. Use of laparoscopy was significantly lower in Colombia (5.9% vs 89.4%; P < .0001). After adjustment for covariates, multivariable logistic regression analyses revealed that compared to the United States, Colombia had lower complication rates (2.8% vs 6.6%; odds ratio [OR], 0.41; 95% confidence interval [CI], 0.39-0.44; P < .0001) but higher mortality (0.44% vs 0.08%; OR, 8.92; 95% CI, 5.69-13.98; P < .0001) and failure to rescue (13.6% vs 1.0%; OR, 17.01; 95% CI, 10.66-27.16; P < .0001).

CONCLUSIONS

Despite lower rates of postoperative complications, in-hospital mortality after appendectomy was higher in Colombia than in the United States. This difference may be explained by higher rates of failure to rescue in the low-to-middle-income country (ie, decreased ability of Colombian hospitals to rescue patients from complications).

Use of Telemedicine for Postdischarge Assessment of the Surgical Wound: International Cohort Study, and Systematic Review With Meta-analysis

OBJECTIVE

This study aimed to determine whether remote wound reviews using telemedicine can be safely upscaled, and if standardized assessment tools are needed.

BACKGROUND

Surgical site infection (SSI) is the most common complication of surgery worldwide, and frequently occurs after hospital discharge. Evidence to support implementation of telemedicine during postoperative recovery will be an essential component of pandemic recovery.

METHODS

The primary outcome of this study was SSI reported up to 30 days after surgery (SSI), comparing rates reported using telemedicine (telephone and/or video assessment) to those with in-person review. The first part of this study analyzed primary data from an international cohort study of adult patients undergoing abdominal surgery who were discharged from hospital before 30 days after surgery. The second part combined this data with the results of a systematic review to perform a meta-analysis of all available data conducted in accordance with PRIMSA guidelines (PROSPERO:192596).

RESULTS

The cohort study included 15,358 patients from 66 countries (8069 high, 4448 middle, 1744 low income). Of these, 6907 (45.0%) were followed up using telemedicine. The SSI rate reported using telemedicine was slightly lower than with in-person follow-up (13.4% vs 11.1%, P <0.001), which persisted after risk adjustment in a mixed-effects model (adjusted odds ratio: 0.73, 95% confidence interval: 0.63-0.84, P <0.001). This association was consistent across sensitivity and subgroup analyses, including a propensity-score matched model. In 9 eligible nonrandomized studies identified, a pooled mean of 64% of patients underwent telemedicine follow-up. Upon meta-analysis, the SSI rate reported was lower with telemedicine (odds ratio: 0.67, 0.47-0.94) than in-person (reference) follow-up ( I2 =0.45, P =0.12), although there a high risk of bias in included studies.

CONCLUSIONS

Use of telemedicine to assess the surgical wound postdischarge is feasible, but risks underreporting of SSI. Standardized tools for remote assessment of SSI must be evaluated and adopted as telemedicine is upscaled globally.

Enabling personalized perioperative risk prediction by using a machine-learning model based on preoperative data

Preoperative risk assessment is essential for shared decision-making and adequate perioperative care. Common scores provide limited predictive quality and lack personalized information. The aim of this study was to create an interpretable machine-learning-based model to assess the patient's individual risk of postoperative mortality based on preoperative data to allow analysis of personal risk factors. After ethical approval, a model for prediction of postoperative in-hospital mortality based on preoperative data of 66,846 patients undergoing elective non-cardiac surgery between June 2014 and March 2020 was created with extreme gradient boosting. Model performance and the most relevant parameters were shown using receiver operating characteristic (ROC-) and precision-recall (PR-) curves and importance plots. Individual risks of index patients were presented in waterfall diagrams. The model included 201 features and showed good predictive abilities with an area under receiver operating characteristic (AUROC) curve of 0.95 and an area under precision-recall curve (AUPRC) of 0.109. The feature with the highest information gain was the preoperative order for red packed cell concentrates followed by age and c-reactive protein. Individual risk factors could be identified on patient level. We created a highly accurate and interpretable machine learning model to preoperatively predict the risk of postoperative in-hospital mortality. The algorithm can be used to identify factors susceptible to preoperative optimization measures and to identify risk factors influencing individual patient risk.

A core set of quality performance indicators for HPB procedures: a global consensus for hepatectomy, pancreatectomy, and complex biliary surgery

BACKGROUND

Surgery for hepatopancreaticobiliary (HPB) conditions is performed worldwide. This investigation aimed to develop a set of globally accepted procedural quality performance indicators (QPI) for HPB surgical procedures.

METHODS

A systematic literature review generated a dataset of published QPI for hepatectomy, pancreatectomy, complex biliary surgery and cholecystectomy. Using a modified Delphi process, three rounds were conducted with working groups composed of self-nominating members of the International Hepatopancreaticobiliary Association (IHPBA). The final set of QPI was circulated to the full membership of the IHPBA for review.

RESULTS

Seven "core" indicators were agreed for hepatectomy, pancreatectomy, and complex biliary surgery (availability of specific services on site, a specialised surgical team with at least two certified HPB surgeons, a satisfactory institutional case volume, synoptic pathology reporting, undertaking of unplanned reintervention procedures within 90 days, the incidence of post-procedure bile leak and Clavien-Dindo grade ≥III complications and 90-day post-procedural mortality). Three further procedure specific QPI were proposed for pancreatectomy, six for hepatectomy and complex biliary surgery. Nine procedure-specific QPIs were proposed for cholecystectomy. The final set of proposed indicators were reviewed and approved by 102 IHPBA members from 34 countries.

CONCLUSIONS

This work presents a core set of internationally agreed QPI for HPB surgery.

Hospital Performance on Failure to Rescue Correlates With Likelihood of Home Discharge

INTRODUCTION

Failure to rescue (FTR) (avoiding death after complications) has been proposed as a measure of hospital quality. Although surviving complications is important, not all rescues are created equal. Patients also place considerable values on being able to return home after surgery and resume their normal lives. From a systems standpoint, nonhome discharge to skilled nursing and other facilities is the biggest driver of Medicare costs. We wanted to determine whether hospitals' ability to keep patients alive after complications was associated with higher rates of home discharge. We hypothesized that hospitals with higher rescue rates would also be more likely to discharge patients home after surgery.

METHODS

We conducted a retrospective cohort study using the nationwide inpatient sample. We included 1,358,041 patients ≥18 y old who had elective major surgery (general, vascular, orthopedic) at 3818 hospitals from 2013 to 2017. We predicted the correlation between a hospital's performance (rank) on FTR and its rank in terms of home discharge rate.

RESULTS

The cohort had a median age of 66 y (interquartile range [IQR] 58-73), and 77.9% of patients were Caucasian. Most patients (63.6%) were treated at urban teaching institutions. The surgical case mix included patients having colorectal (146,993 patients; 10.8%), pulmonary (52,334; 3.9%), pancreatic (13,635; 1.0%), hepatic (14,821; 1.1%), gastric (9182; 0.7%), esophageal (4494; 0.3%), peripheral vascular bypass (29,196; 2.2%), abdominal aneurysm repair (14,327; 1.1%), coronary artery bypass (61,976; 4.6%), hip replacement (356,400; 26.2%), and knee replacement (654,857; 48.2%) operations. The overall mortality was 0.3%, the average hospital complication rate was 15.9%, the median hospital rescue rate was 99% (IQR 70%-100%), and the median hospital rate of home discharge was 80% (IQR 74%-85%).There was a small but positive correlation between hospitals' performance on the FTR metric and the likelihood of home discharge after surgery (r = 0.0453; P = 0.006). When considering hospital rates of discharge to home following a postoperative complication, there was a similar correlation between rescue rates and probability of home discharge (r = 0.0963; P < 0.001). However, on sensitivity analysis excluding orthopedic surgery, there was a stronger correlation between rescue rates and home discharge rate (r = 0.4047, P < 0.001).

CONCLUSIONS

We found a small correlation between a hospital's ability to rescue patients from complication and that hospital's likelihood of discharging patients home after surgery. When excluding orthopedic operations from the analysis, this correlation strengthened. Our findings suggest that efforts to reduce mortality after complications will likely also help patients return home more frequently after complex surgery. However, more work needs to be done to identify successful programs and other patient and hospital factors that affect both rescue and home discharge.

Implementation of a Surgical Critical Care Service Reduces Failure to Rescue in Emergency Gastrointestinal Surgery in Rural Kenya

OBJECTIVE

We aimed to evaluate the implementation of a dedicated Surgical critical care service (SCCS) on failure to rescue (FTR) rates in rural Kenya.

SUMMARY BACKGROUND DATA

FTR adversely impacts perioperative outcomes. In the resource-limited contexts of low- and middle-income countries, emergency gastrointestinal surgery carries high morbidity and mortality rates. Quality improvement initiatives that decrease FTR rates are essential for improving perioperative care.

METHODS

All patients who underwent emergency gastrointestinal surgery between January 2016 and June 2019 at Tenwek Hospital in rural Kenya were reviewed. Critical care capabilities were constant throughout the study period. A supervised surgical resident was dedicated to the daily care of critically ill surgical patients beginning in January 2018. The impact of the SCCS initiation on the outcome of FTR was evaluated, controlling for patient complexity via the African Surgical Outcomes Study Surgical Risk Score.

RESULTS

A total of 484 patients were identified, consisting of 278 without and 206 with an active SCCS. A total of 165 (34.1%) patients experienced postoperative complications, including 49 mortalities (10.1%) yielding an FTR rate of 29.7%. The FTR rate decreased after SCCS implementation from 36.8% (95% CI: 26.7%-47.8%) to 21.8% (95% CI: 13.2%-32.6%) ( P = 0.035) despite an increase in the average patient African Surgical Outcomes Study score from 14.5 (95% CI, 14.1-14.9) to 15.2 (95% CI, 14.7-15.7) ( P =0.03).

CONCLUSIONS

The implementation of an SCCS in rural Kenya resulted in decreased rates of FTR despite an increase in patient complexity and severity of critical illness.

Postoperative outcomes associated with surgical care for women in Africa: an international risk-adjusted analysis of prospective observational cohorts

Background

Improving women's health is a critical component of the sustainable development goals. Although obstetric outcomes in Africa have received significant focus, non-obstetric surgical outcomes for women in Africa remain under-examined.

Methods

We did a secondary analysis of the African Surgical Outcomes Study (ASOS) and International Surgical Outcomes Study (ISOS), two 7-day prospective observational cohort studies of outcomes after adult inpatient surgery. This sub-study focuses specifically on the analysis of the female, elective, non-obstetric, non-gynaecological surgical data collected during these two large multicentre studies. The African data from both cohorts are compared with international (non-African) outcomes in a risk-adjusted logistic regression analysis using a generalised linear mixed-effects model. The primary outcome was severe postoperative complications including in-hospital mortality in Africa compared with non-African outcomes.

Results

A total of 1698 African participants and 18 449 international participants met the inclusion criteria. The African cohort were younger than the international cohort with a lower preoperative risk profile. Severe complications occurred in 48 (2.9%) of 1671, and 431 (2.3%) of 18 449 patients in the African and international cohorts, respectively, with in-hospital mortality after severe complications of 23/48 (47.9%) in Africa and 78/431 (18.1%) internationally. Women in Africa had an adjusted odds ratio of 2.06 (95% confidence interval, 1.17-3.62; P=0.012) of developing a severe postoperative complication after elective non-obstetric, non-gynaecological surgery, compared with the international cohort.

Conclusions

Women in Africa have double the risk adjusted odds of severe postoperative complications (including in-hospital mortality) after elective non-obstetric, non-gynaecological surgery compared with the international incidence.

Long-term mortality following complications after elective surgery: a secondary analysis of pooled data from two prospective cohort studies

BACKGROUND

Complications after surgery affect survival and quality of life. We aimed to confirm the relationship between postoperative complications and death within 1 yr after surgery.

METHODS

We conducted a secondary analysis of pooled data from two prospective cohort studies of patients undergoing surgery in five high-income countries between 2012 and 2014. Exposure was any complication within 30 days after surgery. Primary outcome was death within 1 yr after surgery, ascertained by direct follow-up or linkage to national registers. We adjusted for clinically important covariates using a mixed-effect multivariable Cox proportional hazards regression model. We conducted a planned subgroup analysis by type of complication. Data are presented as mean with standard deviation (sd), n (%), and adjusted hazard ratios (aHRs) with 95% confidence intervals (CIs).

RESULTS

The pooled cohort included 10 132 patients. After excluding 399 (3.9%) patients with missing data or incomplete follow-up, 9733 patients were analysed. The mean age was 59 [sd 16.8] yr, and 5362 (55.1%) were female. Of 9733 patients, 1841 (18.9%) had complications within 30 days after surgery, and 319 (3.3%) died within 1 yr after surgery. Of 1841 patients with complications, 138 (7.5%) died within 1 yr after surgery compared with 181 (2.3%) of 7892 patients without complications (aHR 1.94 [95% CI: 1.53-2.46]). Respiratory failure was associated with the highest risk of death, resulting in six deaths amongst 28 patients (21.4%).

CONCLUSIONS

Postoperative complications are associated with increased mortality at 1 yr. Further research is needed to identify patients at risk of complications and to reduce mortality.

Use of failure-to-rescue after emergency surgery as a dynamic indicator of hospital resilience during the COVID-19 pandemic. A multicenter retrospective propensity score-matched cohort study

Background

Surgical failure-to-rescue (FTR, death rate following complications) is a reliable cross-sectional quality of care marker, but has not been evaluated dynamically. We aimed to study changes in FTR following emergency surgery during the COVID-19 pandemic.

Material and methods

Matched cohort study including all COVID-19-non-infected adult patients undergoing emergency general surgery in 25 Spanish hospitals during COVID-19 pandemic peak (March–April 2020), non-peak (May–June 2020), and 2019 control periods. A propensity score-matched comparative analysis was conducted using a logistic regression model, in which period was regressed on observed baseline characteristics. Subsequently, a mixed effects logistic regression model was constructed for each variable of interest. Main variable was FTR. Secondary variables were post-operative complications, readmissions, reinterventions, and length of stay.

Results

5003 patients were included (948, 1108, and 2947 in the pandemic peak, non-peak, and control periods), with comparable clinical characteristics, prognostic scores, complications, reintervention, rehospitalization rates, and length of stay across periods. FTR was greater during the pandemic peak than during non-peak and pre-pandemic periods (22.5% vs. 17.2% and 12.7%), being this difference confirmed in adjusted analysis (odds ratio [OR] 2.13, 95% confidence interval [95% CI] 1.27–3.66). There was sensible inter-hospital variability in FTR changes during the pandemic peak (median FTR change +8.77%, IQR 0–29.17%) not observed during the pandemic non-peak period (median FTR change 0%, IQR -6.01−6.72%). Greater FTR increase was associated with higher COVID-19 incidence (OR 2.31, 95% CI 1.31–4.16) and some hospital characteristics, including tertiary level (OR 3.07, 95% CI 1.27–8.00), medium-volume (OR 2.79, 95% CI 1.14–7.34), and high basal-adjusted complication risk (OR 2.21, 95% CI 1.07–4.72).

Conclusion

FTR following emergency surgery experienced a heterogeneous increase during different periods of the COVID-19 pandemic, suggesting it to behave as an indicator of hospital resilience. FTR monitoring could facilitate identification of centres in special needs during ongoing health care challenges.

Effect of Intelligent Medical Data Technology in Postoperative Nursing Care

Surgery is one of the larger wounds in conventional surgery, and patients often experience different pain and postural discomfort after surgery. With the ever-changing standards of medical care and patient care requirements, providing high-quality care to postoperative patients is an important measure to reduce complications and promote rapid recovery. However, in the traditional postsurgical nursing methods, there are often the phenomenon that wrong patients are connected, patient data is messy, and medicines are counted incorrectly, which directly leads to a rapid decline in nursing efficiency. In the context of the rapid development of artificial intelligence and big data, intelligent medical data analysis technology has gradually been integrated into the medical field. This paper analyzes and studies the application effect of intelligent medical data analysis technology in postoperative nursing. It is aimed at changing the traditional postoperative nursing methods and improving nursing efficiency, and it provides important suggestions for the development of postoperative nursing in the new era. Combining big data and Internet of Things technology, this paper builds a smart medical Internet of Things framework and an intelligent postoperative care system and uses machine learning algorithms to preprocess relevant medical data. The final experimental results show that the intelligent medical data analysis technology has a good effect in improving the nursing efficiency after surgery, and the nursing efficiency has increased by 6.9%.

Value in acute care surgery, part 2: Defining and measuring quality outcomes

ABSTRACT

The prior article in this series delved into measuring cost in acute care surgery, and this subsequent work explains in detail how quality is measured. Specifically, objective quality is based on outcome measures, both from administrative and clinical registry databases from a multitude of sources. Risk stratification is key in comparing similar populations across diseases and procedures. Importantly, a move toward focusing on subjective outcomes like patient-reported outcomes measures and financial well-being are vital to evolving surgical quality measures for the 21st century.

A pragmatic method to compare international critical care beds: Implications to pandemic preparedness and non-pandemic planning

BACKGROUND

The current method for assessing critical care (CCU) bed numbers between countries is unreliable.

METHODS

A pragmatic method is presented using a logarithmic relationship between CCU beds per 1000 deaths and deaths per 1000 population, both of which are readily available. The method relies on the importance of the nearness to death effect, and on the effect of population size.

RESULTS

The method was tested using CCU bed numbers from 65 countries. A series of logarithmic relationships can be seen. High versus low countries can be distinguished by adjusting all countries to a common crude mortality rate. Hence at 9.5 deaths per 1000 population 'high' CCU bed countries average of around 30 CCU beds per 1000 deaths, while 'very low' countries only average 3 CCU beds per 1000 deaths. The United Kingdom falls among countries with low critical care provision with an average of 8 CCU beds per 1000 deaths, and during the COVID-19 epidemic UK industry intervened to rapidly manufacture various types of ventilators to avoid a catastrophe. CCU bed numbers in India are around 8.1 per 1000 deaths, which places it in the low category. However, such beds are inequitably distributed with the poorest states all in the 'very low' category. In India only around 50% of CCU beds have a ventilator.

CONCLUSION

A feasible region is defined for the optimum number of CCU beds.

The need for data describing the surgical population in Latin America

Latin American countries have a huge diversity in sociocultural factors, ethnicity, geography, and political systems. Provision of healthcare varies widely in Latin America, and it is unclear how these disparities relate to outcomes for individual patients undergoing surgery. The Latin American Surgical Outcome Study (LASOS), with its pragmatic design, will provide a snapshot of surgical activity throughout Latin America and identify the next steps needed to improve postoperative outcomes.

Wireless wearables for postoperative surveillance on surgical wards: a survey of 1158 anaesthesiologists in Western Europe and the USA

Background

Several continuous monitoring solutions, including wireless wearable sensors, are available or being developed to improve patient surveillance on surgical wards. We designed a survey to understand the current perception and expectations of anaesthesiologists who, as perioperative physicians, are increasingly involved in postoperative care.

Methods

The survey was shared in 40 university hospitals from Western Europe and the USA.

Results

From 5744 anaesthesiologists who received the survey link, there were 1158 valid questionnaires available for analysis. Current postoperative surveillance was mainly based on intermittent spot-checks of vital signs every 4-6 h in the USA (72%) and every 8-12 h in Europe (53%). A majority of respondents (91%) considered that continuous monitoring of vital signs should be available on surgical wards and that wireless sensors are preferable to tethered systems (86%). Most respondents indicated that oxygen saturation (93%), heart rate (80%), and blood pressure (71%) should be continuously monitored with wrist devices (71%) or skin adhesive patches (54%). They believed it may help detect clinical deterioration earlier (90%), decrease rescue interventions (59%), and decrease hospital mortality (54%). Opinions diverged regarding the impact on nurse workload (increase 46%, decrease 39%), and most respondents considered that the biggest implementation challenges are economic (79%) and connectivity issues (64%).

Conclusion

Continuous monitoring of vital signs with wireless sensors is wanted by most anaesthesiologists from university hospitals in Western Europe and in the USA. They believe it may improve patient safety and outcome, but may also be challenging to implement because of cost and connectivity issues.

Enhanced peri-operative care to improve outcomes for high-risk surgical patients in Brazil: a single-centre before-and-after cohort study

Mortality and morbidity for high-risk surgical patients are often high, especially in low-resource settings. Enhanced peri-operative care has the potential to reduce preventable deaths but must be designed to meet local needs. This before-and-after cohort study aimed to assess the effectiveness of a postoperative 48-hour enhanced care pathway for high-risk surgical patients ('high-risk surgical bundle') who did not meet the criteria for elective admission to intensive care. The pathway comprised of six elements: risk identification and communication; adoption of a high-risk post-anaesthesia care unit discharge checklist; prompt nursing admission to ward; intensification of vital signs monitoring; troponin measurement; and prompt access to medical support if required. The primary outcome was in-hospital mortality. Data describing 1189 patients from two groups, before and after implementation of the pathway, were compared. The usual care group comprised a retrospective cohort of high-risk surgical patients between September 2015 and December 2016. The intervention group prospectively included high-risk surgical patients from February 2019 to March 2020. Unadjusted mortality rate was 10.5% (78/746) for the usual care and 6.3% (28/443) for the intervention group. After adjustment, the intervention effect remained significant (RR 0.46 (95%CI 0.30-0.72). The high-risk surgical bundle group received more rapid response team calls (24% vs. 12.6%; RR 0.63 [95%CI 0.49-0.80]) and surgical re-interventions (18.9 vs. 7.5%; RR 0.41 [95%CI 0.30-0.59]). These data suggest that a clinical pathway based on enhanced surveillance for high-risk surgical patients in a resource-constrained setting could reduce in-hospital mortality.

The impact of the incorporation of a feasible postoperative mortality model at the Post-Anaesthestic Care Unit (PACU) on postoperative clinical deterioration: A pragmatic trial with 5,353 patients

Background

Practical use of risk predictive tools and the assessment of their impact on outcome reduction is still a challenge. This pragmatic study of quality improvement (QI) describes the preoperative adoption of a customised postoperative death probability model (SAMPE model) and the evaluation of the impact of a Postoperative Anaesthetic Care Unit (PACU) pathway on the clinical deterioration of high-risk surgical patients.

Methods

A prospective cohort of 2,533 surgical patients compared with 2,820 historical controls after the adoption of a quality improvement (QI) intervention. We carried out quick postoperative high-risk pathways at PACU when the probability of postoperative death exceeded 5%. As outcome measures, we used the number of rapid response team (RRT) calls within 7 and 30 postoperative days, in-hospital mortality, and non-planned Intensive Care Unit (ICU) admission.

Results

Not only did the QI succeed in the implementation of a customised risk stratification model, but it also diminished the postoperative deterioration evaluated by RRT calls on very high-risk patients within 30 postoperative days (from 23% before to 14% after the intervention, p = 0.05). We achieved no survival benefits or reduction of non-planned ICU. The small group of high-risk patients (13% of the total) accounted for the highest proportion of RRT calls and postoperative death.

Conclusion

Employing a risk predictive tool to guide immediate postoperative care may influence postoperative deterioration. It encouraged the design of pragmatic trials focused on feasible, low-technology, and long-term interventions that can be adapted to diverse health systems, especially those that demand more accurate decision making and ask for full engagement in the control of postoperative morbi-mortality.

Validation of Heart Rate Extracted From Wrist-Based Photoplethysmography in the Perioperative Setting: Prospective Observational Study

Background

Measurement of heart rate (HR) through an unobtrusive, wrist-worn optical HR monitor (OHRM) could enable earlier recognition of patient deterioration in low acuity settings and enable timely intervention.

Objective

The goal of this study was to assess the agreement between the HR extracted from the OHRM and the gold standard 5-lead electrocardiogram (ECG) connected to a patient monitor during surgery and in the recovery period.

Methods

In patients undergoing surgery requiring anesthesia, the HR reported by the patient monitor’s ECG module was recorded and stored simultaneously with the photopletysmography (PPG) from the OHRM attached to the patient’s wrist. The agreement between the HR reported by the patient’s monitor and the HR extracted from the OHRM’s PPG signal was assessed using Bland-Altman analysis during the surgical and recovery phase.

Results

A total of 271.8 hours of data in 99 patients was recorded simultaneously by the OHRM and patient monitor. The median coverage was 86% (IQR 65%-95%) and did not differ significantly between surgery and recovery (Wilcoxon paired difference test P=.17). Agreement analysis showed the limits of agreement (LoA) of the difference between the OHRM and the ECG HR were within the range of 5 beats per minute (bpm). The mean bias was –0.14 bpm (LoA between –3.08 bpm and 2.79 bpm) and –0.19% (LoA between –5 bpm to 5 bpm) for the PPG- measured HR compared to the ECG-measured HR during surgery; during recovery, it was –0.11 bpm (LoA between –2.79 bpm and 2.59 bpm) and –0.15% (LoA between –3.92% and 3.64%).

Conclusions

This study shows that an OHRM equipped with a PPG sensor can measure HR within the ECG reference standard of –5 bpm to 5 bpm or –10% to 10% in the perioperative setting when the PPG signal is of sufficient quality. This implies that an OHRM can be considered clinically acceptable for HR monitoring in low acuity hospitalized patients.

In-hospital survival after pancreatoduodenectomy is greater in high-volume hospitals versus lower-volume hospitals: a meta-analysis

BACKGROUND

Variation in cut-off values for what is considered a high volume (HV) hospital has made assessments of volume-outcome relationships for pancreaticoduodenectomy (PD) challenging. Accordingly, we performed a systematic review and meta-analysis comparing in-hospital mortality after PD in hospitals above and below HV thresholds of various cut-off values.

METHOD

PubMed/MEDLINE, Embase and Cochrane Library were searched to 4 January 2021 for studies comparing in-hospital mortality after PD in hospitals above and below defined HV thresholds. After data extraction, risk of bias was assessed using the Downs and Black checklist. A random-effects model was used for meta-analysis, including meta-regressions. Registration: PROSPERO, CRD42021224432.

RESULTS

From 1855 records, 17 observational studies of moderate quality were included. Median HV cut-off was 25 PDs/year (IQR: 20-32). Overall relative risk of in-hospital mortality was 0.37 (95% CI: 0.30, 0.45), that is, 63% less in HV hospitals. All subgroup analyses found an in-hospital survival benefit in performing PDs at HV hospitals. Meta-regressions from included studies found no statistically significant associations between relative risk of in-hospital mortality and region (USA vs. non-USA; p = 0.396); or 25th percentile (p = 0.231), median (p = 0.822) or 75th percentile (p = 0.469) HV cut-off values. Significant inverse relationships were found between PD hospital volume and other outcomes.

CONCLUSION

In-hospital survival was significantly greater for patients undergoing PDs at HV hospitals, regardless of HV cut-off value or region. Future research is required to investigate regions where low-volume centres have specialized PD infrastructure and the potential impact on mortality.

The discussion of risk in German surgical clinical practice guidelines: a qualitative review

Objectives

Clinical practice guidelines (CPGs) have a potentially important role regarding the assessment and communication of the risks of perioperative complications. This study aimed to (1) examine the content of German surgical CPGs in relation to surgical risks and (2) provide baseline results for future research in order to assess the development of surgical CPGs in Germany in relation to this issue.

Methods

In November 2015, all German surgical CPGs that provide guidance regarding illnesses that can be treated with a surgical procedure were collected from the websites of the German umbrella organisation of medical professional associations and the German Association for Cardiology.

Results

Data collection retrieved 230 CPGs of which 214 were included in the final analysis. The analysis identified four different groups: 1) 5% (10/214) of guidelines did not discuss “risks” or “complications” at all; 2) 21% (44/214) of guidelines discussed general risks that are not related to surgical complications; 3) 35% (76/214) of guidelines discussed surgical complications and often discussed their likelihood in terms of “high risk” or “low risk”, but did not provide numeric estimates and 4) 39% (84/214) of guidelines discussed specific surgical risks and also provided numerical risk estimates. Guidelines with higher methodological quality more frequently included numerical risk estimates.

Conclusions

It is positive that the vast majority of German surgical CPGs address the issue of risks. However, it would be helpful if more German surgical CPGs provide explicit and evidence-based estimates and recommendations relating to the surgical risk to support surgeons in providing high-quality care and to meet their ethical obligations to patients.

New nurse graduates and rapidly changing clinical situations: the role of expert critical care nurse mentors

OBJECTIVES

New nurse graduates may be prone to instances of failure to rescue. Mentoring programs may be an opportunity to assist them with clinical decision making in situations of patient decline. We explored the experiences of new nurse graduates and expert nurses after participation in a mentoring program.

METHODS

In this exploratory-descriptive study, five seasoned nurses were paired with five new nurse graduates. After four months, the new nurse graduates were interviewed, and the expert nurses participated in a focus group.

RESULTS

Themes emerged for the new nurse graduates: 1) importance of the charge nurse, 2) differences in practice areas, and 3) supportive healthcare teams. The focus group revealed three themes: 1) remembering what it was like, 2) desiring to help, and 3) having confidence in their preparation as mentors.

CONCLUSIONS

New nurse graduates relied on charge nurses for assistance. Therefore, it is imperative that charge nurses receive adequate support.

High-fidelity simulation and nurse clinical competence-An integrative review

AIM

The aim of this review was to synthesise current knowledge of high-fidelity simulation practices and its impact on nurse clinical competence in the acute care setting.

BACKGROUND

There is no consensus or standardisation surrounding best practices for the delivery of high-fidelity simulation in the acute care setting. This is an understudied area.

DESIGN

An integrative review using Johns Hopkins Nursing Evidence-Based Practice Model.

METHODS

Medical subject heading terms 'Clinical Competence', AND 'High Fidelity Simulation Training', AND 'Clinical Deterioration' were systematically searched in PubMed, CINAHL and Embase databases for peer-reviewed literature published through September 2020. The current study was evaluated using PRISMA checklist.

RESULTS

Seven studies met the inclusion criteria. Three main concepts were identified: modes of delivery, approach to learner participation and outcome measurement.

CONCLUSIONS

This review substantiated the use of high-fidelity simulation to improve acute care nurses' early identification and management of clinical deterioration. Global variations in course design and implementation highlight the need for future approaches to be standardised at the regional level (i.e., country-centric approach) where differing scopes of practice and sociocultural complexities are best contextualised.

RELEVANCE TO CLINICAL PRACTICE

These findings add to the growing body of evidence of simulation science. Important considerations in course planning and design for nursing clinical educators were uncovered. This is especially relevant given the current COVID-19 pandemic and urgent need to train redeployed nurses safely and effectively from other units and specialties to acute care.

Enhanced postoperative surveillance versus standard of care to reduce mortality among adult surgical patients in Africa (ASOS-2): a cluster-randomised controlled trial

Background

Risk of mortality following surgery in patients across Africa is twice as high as the global average. Most of these deaths occur on hospital wards after the surgery itself. We aimed to assess whether enhanced postoperative surveillance of adult surgical patients at high risk of postoperative morbidity or mortality in Africa could reduce 30-day in-hospital mortality.

Methods

We did a two-arm, open-label, cluster-randomised trial of hospitals (clusters) across Africa. Hospitals were eligible if they provided surgery with an overnight postoperative admission. Hospitals were randomly assigned through minimisation in recruitment blocks (1:1) to provide patients with either a package of enhanced postoperative surveillance interventions (admitting the patient to higher care ward, increasing the frequency of postoperative nursing observations, assigning the patient to a bed in view of the nursing station, allowing family members to stay in the ward, and placing a postoperative surveillance guide at the bedside) for those at high risk (ie, with African Surgical Outcomes Study Surgical Risk Calculator scores ≥10) and usual care for those at low risk (intervention group), or for all patients to receive usual postoperative care (control group). Health-care providers and participants were not masked, but data assessors were. The primary outcome was 30-day in-hospital mortality of patients at low and high risk, measured at the participant level. All analyses were done as allocated (by cluster) in all patients with available data. This trial is registered with ClinicalTrials.gov, NCT03853824.

Findings

Between May 3, 2019, and July 27, 2020, 594 eligible hospitals indicated a desire to participate across 33 African countries; 332 (56%) were able to recruit participants and were included in analyses. We allocated 160 hospitals (13 275 patients) to provide enhanced postoperative surveillance and 172 hospitals (15 617 patients) to provide standard care. The mean age of participants was 37·1 years (SD 15·5) and 20 039 (69·4%) of 28 892 patients were women. 30-day in-hospital mortality occurred in 169 (1·3%) of 12 970 patients with mortality data in the intervention group and in 193 (1·3%) of 15 242 patients with mortality data in the control group (relative risk 0·96, 95% CI 0·69–1·33; p=0·79). 45 (0·2%) of 22 031 patients at low risk and 309 (5·6%) of 5500 patients at high risk died. No harms associated with either intervention were reported.

Interpretation

This intervention package did not decrease 30-day in-hospital mortality among surgical patients in Africa at high risk of postoperative morbidity or mortality. Further research is needed to develop interventions that prevent death from surgical complications in resource-limited hospitals across Africa.

Association between Hospital Volume and Failure to Rescue after Open or Endovascular Repair of Intact Abdominal Aortic Aneurysms in the VASCUNET and International Consortium of Vascular Registries

OBJECTIVE

To investigate the association between hospital volume and failure to rescue (FtR), after open (OAR) and endovascular (EVAR) repair of intact abdominal aortic aneurysms (AAA) among centers participating in the VASCUNET and International Consortium of Vascular Registries (ICVR).

SUMMARY BACKGROUND DATA

FtR (i.e., in-hospital death following major complications) is a composite end-point representing the inability to treat complications effectively and prevent death.

METHODS

Using data from eight vascular registries, complication and mortality rates after intact AAA repair were examined (n = 60,273; EVAR-43,668; OAR-16,605). A restricted analysis using pooled data from four countries (Australia, Hungary, New Zealand, USA) reporting data on all postoperative complications (bleeding, stroke, cardiac, respiratory, renal, colonic ischemia) was performed to identify risk-adjusted association between hospital volume and FtR.

RESULTS

The most frequently reported complications were cardiac (EVAR-3.0%, OAR-8.9%) and respiratory (EVAR-1.0%, OAR-5.7%). In adjusted analysis, 4.3% of EVARs and 18.5% of OARs had at least one complication. The overall FtR rate was 10.3% after EVAR and 15.7% after OAR. Subjects treated in the highest volume centers(Q4) had 46% and 80% lower odds of FtR after EVAR (OR = 0.54; 95%CI = 0.34-0.87;p = 0.04) and OAR (OR = 0.22; 95%CI = 0.11-0.44;p < 0.001) when compared to lowest volume centers(Q1), respectively. Colonic ischemia had the highest risk of FtR for both procedures (adjusted predicted risks, EVAR: 27%, 95%CI 14%-45%; OAR: 30%, 95%CI 17%-46%).

CONCLUSIONS

In this multi-national dataset, FtR rate after intact AAA repair with EVAR and OAR is significantly associated with hospital volume. Hospitals in the top volume quartiles achieve the lowest mortality after a complication has occurred.

[Perioperative Management: from the OR to the ICU]

Patients who undergo high-risk surgical procedures represent a large proportion of admissions to intensive care units. Postoperative outcomes are a result of the complex interplay between the exact surgical procedure performed, the previous health of the patient, and specific intra- and postoperative events. Appropriate triage of patients to intensive care postoperatively may have a relevant impact on patient outcomes after high-risk surgery. It remains challenging to accurately identify patients who are at high risk of complications or death and target the patients who will benefit most from this highest level of postoperative care. "Failure to rescue" as an expression for the proportion of deaths in patients who developed a postoperative complication out of the total number of patients who developed a postoperative complication adds to the mortality of surgical patients. General wards may not properly recognize and manage postoperative complications when they occur which emphasises the necessity for adequate triage of intensive care capacity. When admission to the intensive care unit is granted patient transport from the operating room to the intensive care unit and patient handover to ICU-staff are further issues relevant to postoperative patient safety. Intrahospital transports are prone to adverse events and need careful preparation to be executed safely. In addition, exchange of clinical information during the transfer of responsibility between anesthesiologist and the intensive care physician has been recognized as a high-risk area for medical errors to occur. Structured handover protocols can reduce communication breakdowns during postoperative transfer of patients from the OR to the ICU.

Appendicitis Mortality in a Resource-Limited Setting: Issues of Access and Failure to Rescue

BACKGROUND

Appendicitis is one of the most common emergency surgery conditions worldwide, and the incidence is increasing in low- and middle-income countries. Disparities in access to care can lead to disproportionate morbidity and mortality in resource-limited settings; however, outcomes following an appendectomy in low- and middle-income countries remain poorly described. Therefore, we aimed to describe the characteristics and outcomes of patients with appendicitis presenting to a tertiary care center in Malawi.

METHODS

We conducted a retrospective analysis of the Kamuzu Central Hospital (KCH) Acute Care Surgery database from 2013 to 2020. We included all patients ≥13 years with a postoperative diagnosis of acute appendicitis. We performed bivariate analysis by mortality, followed by a modified Poisson regression analysis to determine predictors of mortality.

RESULTS

We treated 214 adults at KCH for acute appendicitis. The majority experienced prehospital delays to care, presenting at least 1 week from symptom onset (n = 99, 46.3%). Twenty (9.4%) patients had appendiceal perforation. Mortality was 5.6%. The presence of a postoperative complication the only statistically significant predictor of mortality (RR 5.1 [CI 1.13-23.03], P = 0.04) when adjusting for age, shock, transferring, and time to presentation.

CONCLUSIONS

Delay to intervention due to inadequate access to care predisposes our population for worse postoperative outcomes. The increased risk of mortality associated with resultant surgical complications suggests that failure to rescue is a significant contributor to appendicitis-related deaths at KCH. Improvement in barriers to diagnosis and management of complications is necessary to reduce further preventable deaths from this disease.

Global variation in postoperative mortality and complications after cancer surgery: a multicentre, prospective cohort study in 82 countries

BACKGROUND

80% of individuals with cancer will require a surgical procedure, yet little comparative data exist on early outcomes in low-income and middle-income countries (LMICs). We compared postoperative outcomes in breast, colorectal, and gastric cancer surgery in hospitals worldwide, focusing on the effect of disease stage and complications on postoperative mortality.

METHODS

This was a multicentre, international prospective cohort study of consecutive adult patients undergoing surgery for primary breast, colorectal, or gastric cancer requiring a skin incision done under general or neuraxial anaesthesia. The primary outcome was death or major complication within 30 days of surgery. Multilevel logistic regression determined relationships within three-level nested models of patients within hospitals and countries. Hospital-level infrastructure effects were explored with three-way mediation analyses. This study was registered with ClinicalTrials.gov, NCT03471494.

FINDINGS

Between April 1, 2018, and Jan 31, 2019, we enrolled 15 958 patients from 428 hospitals in 82 countries (high income 9106 patients, 31 countries; upper-middle income 2721 patients, 23 countries; or lower-middle income 4131 patients, 28 countries). Patients in LMICs presented with more advanced disease compared with patients in high-income countries. 30-day mortality was higher for gastric cancer in low-income or lower-middle-income countries (adjusted odds ratio 3·72, 95% CI 1·70-8·16) and for colorectal cancer in low-income or lower-middle-income countries (4·59, 2·39-8·80) and upper-middle-income countries (2·06, 1·11-3·83). No difference in 30-day mortality was seen in breast cancer. The proportion of patients who died after a major complication was greatest in low-income or lower-middle-income countries (6·15, 3·26-11·59) and upper-middle-income countries (3·89, 2·08-7·29). Postoperative death after complications was partly explained by patient factors (60%) and partly by hospital or country (40%). The absence of consistently available postoperative care facilities was associated with seven to 10 more deaths per 100 major complications in LMICs. Cancer stage alone explained little of the early variation in mortality or postoperative complications.

INTERPRETATION

Higher levels of mortality after cancer surgery in LMICs was not fully explained by later presentation of disease. The capacity to rescue patients from surgical complications is a tangible opportunity for meaningful intervention. Early death after cancer surgery might be reduced by policies focusing on strengthening perioperative care systems to detect and intervene in common complications.

Postoperative Outcomes Following Elective Surgery in India

Introduction

The incidence of complications and mortality in patients undergoing elective surgery in India are unknown. We contributed Indian data to ISOS. Since there were fewer than ten centers, Indian data were not included in the primary analysis. We report postoperative outcomes in the Indian data set of patients following elective surgery.

Materials and methods

In this prospective 7-day observational study, after obtaining a waiver of informed consent, data were collected for 30 days from consecutive patients >18 years undergoing elective surgery. The primary outcome was in-hospital postoperative complications. The secondary outcomes were in-hospital all-cause mortality, the relationship between postoperative complications and admission to critical care, and the duration of hospital stay. Complications were graded as mild, moderate, and severe. Failure to rescue was defined as mortality in patients admitted to an intensive care unit (ICU) for the treatment of complications.

Results

Complications occurred in 57 (27.5%) patients, who were older (53 vs 47 years, p < 0.001) and had American Society of Anaesthesiologists grades III and IV physical status (p = 0.029). One hundred and thirty-eight (65.7%) patients underwent a major surgical procedure of which 132 (62.8%) procedures were done for malignancy. Postoperative complications were significantly higher (41.5% vs 22.7%) in patients electively admitted to ICU. The overall mortality rate was 2.4%, whereas the mortality rate was 8.8% in those who developed complications.

Conclusion

We found that 28% of patients developed postoperative complications. The overall mortality was 2.4% but was higher (8.8%) in those who developed complications. Age and complex surgical procedures independently predicted complications, while lower preoperative hemoglobin appeared to be protective.

Preoperative anemia and surgical outcomes following laparotomy in a resource-limited setting

INTRODUCTION

Anemia is a common and potentially modifiable condition in sub-Saharan Africa. We sought to determine the role of preoperative anemia on post laparotomy abdominal complications.

METHODS

We conducted a six-month prospective, observational study of patients age >12 years following laparotomy at a tertiary hospital in Malawi. The outcome was the occurrence of abdominal complications. Poisson regression analyses estimated the risk of abdominal complications in patients with moderate/severe anemia.

RESULTS

Of 280 patients, most were male (76.4%) with median age of 35 years (IQR 24-50). Abdominal complications developed in 34 patients (15.2%). Of the 224 patients with known preoperative hemoglobin 54 (20.7%) were moderately or severely anemic at the time of surgery. Patients with moderate-to-severe anemia had an increased risk of abdominal complications (RR 4.44, 95% CI 2.0-9.6).

CONCLUSION

Anemia is a common but modifiable comorbidity among laparotomy patients and independently increases the risk of abdominal complications.

Which surgical patients require shared care?

Most hospitalized surgical patients have significant medical comorbidity and are treated with a considerable number of drugs and/or experience significant complications. Shared care (SC) is the shared responsibility and authority in managing hospitalized patients. In this article, we discuss whether patients should be selected for SC or not. The various selection criteria are not an exact science nor are they easy to apply. Furthermore, they may leave out many patients who may be good candidates for SC. Perioperative management is essential for preventing postoperative mortality. Failure to rescue (in-hospital mortality secondary to postoperative complications) is the main factor linked to in-hospital surgical mortality and can affect any patient regardless of age, comorbidity, or type of surgery. The component that most reduces failure to rescue is the presence of internists in surgical wards. We believe that all patients hospitalized in surgery departments should receive SC.

Postoperative Complications and Risk of Mortality after Laparotomy in a Resource-Limited Setting

BACKGROUND

Despite increases in surgical capacity in Malawi, minimal data exist on postoperative complications. Identifying surgical management gaps and targeting quality improvement requires detailed, longitudinal complications, and outcome data that assess surgical safety and efficacy.

METHODS

We conducted a 6-mo prospective, observational study of patients >12 y after laparotomy at a tertiary hospital in Lilongwe, Malawi. Outcomes included postoperative complications and mortality. The seniormost rounding physician determined complication diagnoses. Bivariate and Poisson regression analyses identified predictors of mortality.

RESULTS

Only patients undergoing emergent laparotomy (77.8%) died before discharge, so analysis excluded elective cases. Of 189 patients included, the median age was 33.5 y (IQR 22-50.5), 22 (12.2%) had prior abdominal surgery, and 11 (12.1%) were human immunodeficiency virus-positive. Gastrointestinal perforation was the most common diagnosis (35.5%). The most common procedures were primary gastrointestinal repair (24.9%), diverting ostomy (21.2%), and bowel resection with anastomosis (16.4%). Overall postoperative mortality was 14.8%. Intra-abdominal complication occurred in 17 (9.0%) patients, of whom 8 (47.1%) died. Older age (RR 1.05, 95% CI 1.02-1.08, P < 0.001) and intra-abdominal complication (RR 2.88, 95% CI 1.28-6.46, P = 0.01) increased the relative risk of mortality. Preoperative diagnosis, surgical intervention type, and symptom-to-surgery time did not increase the relative risk of mortality.

CONCLUSIONS

The incidence of complications and mortality after laparotomy at a large referral hospital in Malawi is high. Older age and intra-abdominal complications increase the risk of death. Strategies to improve operative mortality in Malawi should prioritize postoperative surveillance and management and continued outcomes reporting.

Exposure to surgery is associated with better long-term outcomes in patients admitted to Swedish intensive care units

BACKGROUND

Long-term outcomes of patients admitted to intensive care units (ICUs) after surgery are unknown. We investigated the long-term effects of surgical exposure prior to ICU admission.

METHODS

Registry-based cohort study. The adjusted effect of surgical exposure for mortality was examined using Cox regression. Secondary analysis with conditional logistic regression in a case-control subpopulation matched for age, gender, and Simplified Acute Physiology Score III (SAPS3) was also conducted.

RESULTS

72 242 adult patients (56.9% males, median age 66 years [IQR 50-76]), admitted to Swedish ICUs in 3-year (2012-2014) were followed for a median of 2026 days (IQR 1745-2293). Cardiovascular diseases (17.5%), respiratory diseases (15.8%), trauma (11.2%), and infections (11.4%) were the leading causes for ICU admission. Mortality at longest follow-up was 49.4%. Age; SAPS3; admissions due to malignancies, respiratory, cardiovascular and renal diseases; and transfer to another ICU were associated with increased mortality. Surgical exposure prior to ICU admission (adjusted hazard ratio [aHR] 0.90; 95% CI 0.87-0.94; P < .001), admissions from the operation theatre (aHR 0.94; CI 0.90-0.99; P = .022) or post-anaesthesia care unit (aHR 0.92; CI 0.87-0.97; P = .003) were associated with decreased mortality. Conditional logistic regression confirmed the association between surgical exposure and decreased mortality (adjusted odds ratio 0.82; CI 0.75-0.91; P < .001).

CONCLUSIONS

Long-term ICU mortality was associated with known risk factors such as age and SAPS3. Transfer to other ICUs also appeared to be a risk factor and requires further investigation. Prior surgical exposure was associated with better outcomes, a noteworthy observation given limited ICU admissions after surgery in Sweden.

Failure to rescue after major abdominal surgery: The role of hospital safety net burden

BACKGROUND

We aimed to examine whether safety-net burden is a significant predictor of failure-to-rescue (FTR) after major abdominal surgery controlling for patient and hospital characteristics, including surgical volume.

METHODS

Data were extracted from the 2007-2011 Nationwide Inpatient Sample. FTR was defined as mortality among patients experiencing major postoperative complications. Differences in rates of complications, mortality, and FTR across quartiles of safety-net burden were assessed with univariate analyses. Multilevel regression models were constructed to estimate the association between FTR and safety-net burden.

RESULTS

Among 238,645 patients, the incidence of perioperative complications, in-hospital mortality, and FTR were 33.7%, 4.4%, and 11.8%, respectively. All the outcomes significantly increased across the quartiles of safety-net burden. In the multilevel regression analyses, safety-net burden was a significant predictor of FTR after adjustment for patient and hospital characteristics, including hospital volume.

CONCLUSION

Increasing hospital safety-net burden is associated with higher odds of FTR for major abdominal surgery.

Towards high-quality peri-operative care: a global perspective

Article 25 of the United Nations' Universal Declaration of Human Rights enshrines the right to health and well-being for every individual. However, universal access to high-quality healthcare remains the purview of a handful of wealthy nations. This is no more apparent than in peri-operative care, where an estimated five billion individuals lack access to safe, affordable and timely surgical care. Delivery of surgery and anaesthesia in low-resource environments presents unique challenges that, when unaddressed, result in limited access to low-quality care. Current peri-operative research and clinical guidance often fail to acknowledge these system-level deficits and therefore have limited applicability in low-resource settings. In this manuscript, the authors priority-set the need for equitable access to high-quality peri-operative care and analyse the system-level contributors to excess peri-operative mortality rates, a key marker of quality of care. To provide examples of how research and investment may close the equity gap, a modified Delphi method was adopted to curate and appraise interventions which may, with subsequent research and evaluation, begin to address the barriers to high-quality peri-operative care in low- and middle-income countries.

Acute Kidney Injury and Risk of Death After Elective Surgery: Prospective Analysis of Data From an International Cohort Study

BACKGROUND

Postoperative acute kidney injury (AKI) is associated with a high mortality rate. However, the relationship among AKI, its associations, and mortality is not well understood.

METHODS

Planned analysis of data was collected during an international 7-day cohort study of adults undergoing elective in-patient surgery. AKI was defined using Kidney Disease Improving Global Outcomes criteria. Patients missing preoperative creatinine data were excluded. We used multivariable logistic regression to examine the relationships among preoperative creatinine-based estimated glomerular filtration rate (eGFR), postoperative AKI, and hospital mortality, accounting for the effects of age, major comorbid diseases, and nature and severity of surgical intervention on outcomes. We similarly modeled preoperative associations of AKI. Data are presented as n (%) or odds ratios (ORs) with 95% confidence intervals.

RESULTS

A total of 36,357 patients were included, 743 (2.0%) of whom developed AKI with 73 (9.8%) deaths in hospital. AKI affected 73 of 196 (37.2%) of all patients who died. Mortality was strongly associated with the severity of AKI (stage 1: OR, 2.57 [1.3-5.0]; stage 2: OR, 8.6 [5.0-15.1]; stage 3: OR, 30.1 [18.5-49.0]). Low preoperative eGFR was strongly associated with AKI. However, in our model, lower eGFR was not associated with increasing mortality in patients who did not develop AKI. Conversely, in older patients, high preoperative eGFR (>90 mL·minute·1.73 m) was associated with an increasing risk of death, potentially reflecting poor muscle mass.

CONCLUSIONS

The occurrence and severity of AKI are strongly associated with risk of death after surgery. However, the relationship between preoperative renal function as assessed by serum creatinine-based eGFR and risk of death dependent on patient age and whether AKI develops postoperatively.
