External validation of the Codman score in colorectal surgery: a pragmatic tool to drive quality improvement.

AIM: The simple six-variable Codman score is a tool designed to reduce the complexity of contemporary risk-adjusted postoperative mortality rate predictions. We sought to externally validate the Codman score in colorectal surgery. METHODS: The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) participant user file and colectomy targeted dataset of 2020 were merged. A Codman score (composed of six variables: age, American Society of Anesthesiologists score, emergency status, degree of sepsis, functional status and preoperative blood transfusion) was assigned to every patient. The primary outcome was in-hospital mortality and secondary outcome was morbidity at 30 days. Logistic regression analyses were performed using the Codman score and the ACS NSQIP mortality and morbidity algorithms as independent variables for the primary and secondary outcomes. The predictive performance of discrimination area under receiver operating curve (AUC) and calibration of the Codman score and these algorithms were compared. RESULTS: A total of 40 589 patients were included and a Codman score was generated for 40 557 (99.02%) patients. The median Codman score was 3 (interquartile range 1-4). To predict mortality, the Codman score had an AUC of 0.92 (95% CI 0.91-0.93) compared to the NSQIP mortality score 0.93 (95% CI 0.92-0.94). To predict morbidity, the Codman score had an AUC of 0.68 (95% CI 0.66-0.68) compared to the NSQIP morbidity score 0.72 (95% CI 0.71-0.73). When body mass index and surgical approach was added to the Codman score, the performance was no different to the NSQIP morbidity score. The calibration of observed versus expected predictions was almost perfect for both the morbidity and mortality NSQIP predictions, and only well fitted for Codman scores of less than 4 and greater than 7. CONCLUSION: We propose that the six-variable Codman score is an efficient and actionable method for generating validated risk-adjusted outcome predictions and comparative benchmarks to drive quality improvement in colorectal surgery.

A Prospective Audit of 805 Consecutive Patients With Penetrating Abdominal Trauma: Evolving Beyond Injury Mechanism Dictating Management.

BACKGROUND: Global trends of penetrating abdominal trauma (PAT) have seen a shift toward a selectively conservative management strategy. However, its widespread adoption for gunshot injuries has been sluggish. The purpose of this study is to compare the injury mechanisms of gunshot (GSW) and stab wounds (SW) to the abdomen in presentation, management, and outcomes. METHODS: Prospective cohort study, set in Cape Town, South Africa, over 2 years. All patients presenting to the center with PAT during this time were included. Presentation, management, and outcomes were compared by injury mechanism, with a focus on the operative strategy (operative vs nonoperative). RESULTS: During the study period, 805 patients (SW 37.6%; GSW 62.4%) with PAT were managed. Immediate laparotomies were performed in 119 (39.3%) SW and 355 (70.7%) GSW, with a therapeutic laparotomy rate of 85.7% and 91.8% for SW and GSW, respectively. Nonoperative management (NOM) was implemented in 184 SW (60.7%) and 147 GSW (29.3%) (P < 0.001), with a 92.9% and 92.5% success rate for SW and GSW, respectively. The therapeutic laparotomy rate for the delayed laparotomies (DOM) was 69.2% for SW, and 90.9% for GSW. The accuracy of clinical assessment (with adjuncts) in determining the need for laparotomy was: GSW-92% and SW-91%. Univariate analysis revealed the mechanism not to be associated with DOM. The overall mortality rate was 7.2%, and nonfatal morbidities 22.2%. CONCLUSION: Although GSW is a more morbid and often fatal injury, the general principles of selective conservatism hold true for both GSW and SW, equally.

Anastomotic leak after colorectal surgery: does timing affect failure to rescue?

BACKGROUND: Anastomotic leak (AL) is a common complication after colectomy with a relatively high failure to rescue rate (FTR), or death after major complications. There is emerging evidence to suggest an early AL may be associated with increased technical difficulty. Whether the timing of an AL is associated with higher FTR has not been established. METHODS: Patients who underwent a colectomy between 2012 and 2017 were identified from the American College of Surgeons National Quality Improvement Program (ACS NSQIP database). The primary outcome was FTR after AL. The predictor variable used was day of post-operative leak (POD) categorized into early (POD ≤ 3), intermediate (3 < POD ≤ 20) and late (20 < POD ≤ 30) AL. These POD groups were compared to generate hypotheses to explain any association observed between timing of AL and FTR. RESULTS: Of 135,539 identified patients, 4613 patients experienced an AL (3.4%) with an overall FTR of 6.4%. FTR differed by timing of AL: early AL was found to have a FTR of 28/195 (12.6%), with a FTR in intermediate AL of 152/2550 (5.6%) and 3/356 (0.8%) in late AL patients (p < 0.0001). When compared by timing of AL, patients differed by sex, pre-operative bowel preparation, de-functioning ostomy rates and re-operation rates (p < 0.05). Controlling for age, ASA, sex, emergency status, operative approach, indication, de-functioning ostomy, re-operation and concurrent procedure, an early AL was found to have a 2.3-fold increased risk of FTR (95% CI 1.38-3.84, p = 0.001), with a late AL having a 0.15-fold decreased risk (95% CI 0.04-0.49, p = 0.002), both compared to an intermediate AL. CONCLUSION: Early ALs, occurring within three days of surgery, may carry a significant risk of FTR. Given the findings identified here, this may support the use of early detection algorithms and interventions of AL to minimize the risk of FTR.

The effect of operative duration on the outcome of colon cancer procedures.

BACKGROUND: Prolonged operative duration has been associated with increased post-operative morbidity in numerous surgical subspecialties; however, data are limited in operations for colon cancer specifically and existing literature makes unwarranted methodological assumptions of linearity. We sought to assess the effects of extended operative duration on perioperative outcomes in those undergoing segmental colectomy for cancer using a methodologically sound approach. METHODS: We conducted a retrospective cohort study of patients undergoing segmental colectomy for cancer between 2014 and 2018, logged in the National Surgical Quality Improvement Program datasets. Our primary outcome was a composite of any complication within 30 days; secondary outcomes included length of stay and discharge disposition. Our main factor of interest was operative duration. RESULTS: We analyzed 26,380 segmental colectomy cases, the majority of which were approached laparoscopically (64.95%) and were right sided (62.93%). Median operative duration was 152 (95% CI 112-206) minutes. On multivariable regression, increased operative duration was linearly associated with any complication (OR = 1.003, 95% CI 1.003-1.003, p < 0.0001) in the overall cohort, as was length of stay (p < 0.0001). All subgroups except for the laparoscopic left colectomy group were linearly associated with operative duration. In the laparoscopic left colectomy group, an inflection point in the odds of any complication was found at 176 min (OR = 1.39, 95% CI 1.20-1.61, p < 0.0001). CONCLUSIONS: This study suggests that the risk of perioperative complications increases linearly with increasing operative duration, where each additional 30 min increases the odds of complication by 10%. In those undergoing laparoscopic left colectomy, the risk of complications sharply increases after ~ 3 h, suggesting that surgeons should aim to complete these procedures within 3 h where possible.

Will My Patient Survive an Anastomotic Leak? Predicting Failure to Rescue Using the Modified Frailty Index.

IMPORTANCE: Failure to rescue (FTR), or death after major complications, has emerged as a marker of hospital-level quality of care. OBJECTIVE: To evaluate the predictive performance of the ACS-NSQIP modified frailty index (mFI) in determining FTR following an anastomotic leak (AL) after a colectomy for colorectal cancer. DESIGN: Retrospective cohort study. SETTING: Multicenter interrogation of the 2012-2016 American College of Surgeons (ACS) colectomy procedure targeted National Surgical Quality Improvement Program (NSQIP) database. PATIENTS AND METHODS: A total of 50,944 patients who underwent colectomy for colorectal cancer. EXPOSURE: Frailty as measured by: (1) Age, ASA, and emergency status (model 1), (2) Age, ASA, emergency status, and mFI (model 2), (3) ACS-NSQIP mortality prediction (model 3). MAIN OUTCOME AND MEASURE: Primary outcome was FTR after AL. RESULTS: A total of 1755 patients experienced an AL (3.46%) with a FTR rate of 6.44%. The mean age was 65.6 years (95% CI 65.28-65.58 years), median ASA was 3 (IQR 2-3), 51 patients (2.92%) were partially or totally dependent, 366 (20.86%) were diabetic, 105 (5.98%) had a history of chronic obstructive pulmonary disease (COPD), 32 (1.82%) had a history of congestive heart disease (CHD), and 966 (55.04%) were on hypertensive treatment. The performance of model 1 (AUROC 0.77; 95% CI 0.72-0.81), model 2 (AUROC 0.77; 95% CI 0.73-0.82), and model 3 (AUROC 0.79; 95% CI 0.75-0.83) to predict FTR was not different (p = 0.44). CONCLUSIONS AND RELEVANCE: Age and ASA remain the most reliable predictors of failure to rescue anastomotic leak after colectomy for colorectal cancer. Addition of the modified frailty index, or all variables collected by NSQIP, did not significantly improve predictive performance.

Minimally Invasive Surgical Approaches Are Safe and Appropriate in N2 Colorectal Cancer.

BACKGROUND: There is emerging evidence of the oncological safety of minimally invasive surgery in T4 colorectal cancer; however, such support is lacking in N2 disease. OBJECTIVE: This study aimed to compare oncological and perioperative outcomes of surgical resection for N2 colorectal cancer using an open versus minimally invasive approach. DESIGN: We conducted a retrospective cohort study using the National Surgical Quality Improvement Program's generic and targeted colectomy data sets. SETTINGS: Data about surgery for N2 colorectal cancer were obtained regarding North American hospitals participating in the American College of Surgeons National Surgical Quality Improvement Program. PATIENTS: All patients undergoing elective surgical resection for N2 colorectal cancer in participating hospitals between 2014 and 2018 were selected. INTERVENTIONS: Surgical resection of N2 colorectal cancer was performed. MAIN OUTCOME MEASURES: Our primary outcome was nodal yield. Secondary outcomes included perioperative complications and mortality. RESULTS: A total of 1837 patients underwent open and 3907 patients underwent minimally invasive surgery colectomies for N2 colorectal cancer (n = 5744). Median nodal yield was 20 (interquartile range, 15-27) in the open group and 21 (interquartile range, 16-28) in the minimally invasive group (p < 0.0001); however, nodal harvest between the 2 groups was not significantly different on multivariate analysis. Perioperative complications were higher on univariate analysis in the open surgery group, with respect to key outcomes including anastomotic leak and death (p < 0.001). LIMITATIONS: This study is limited by its retrospective design and by the fact that the staging data collected by the National Surgical Quality Improvement Program are pathological rather than clinical; however, prior studies found a 97% concordance between pathological and clinical N2 determination. CONCLUSIONS: Minimally invasive surgery approaches to colorectal cancer with N2 disease result in equivalent nodal harvests compared with open approaches. Our group supports the use of a minimally invasive approach in advanced nodal stage colorectal cancer in the appropriately selected patient. See Video Abstract at http://links.lww.com/DCR/B417.

A New Recalibrated Four-Category Child-Pugh Score Performs Better than the Original Child-Pugh and MELD Scores in Predicting In-Hospital Mortality in Decompensated Alcoholic Cirrhotic Patients with Acute Variceal Bleeding: a Real-World Cohort Analysis.

BACKGROUND: There currently is no consensus on how to accurately predict early rebleeding and death after a major variceal bleed. This study investigated the relative predictive performances of the original Child-Pugh (CP), model for end-stage liver disease (MELD) and a four-category recalibrated Child-Pugh (rCP). METHODS: This prospective study included all adult patients admitted to Groote Schuur Hospital with acute esophageal variceal bleeding secondary to alcoholic cirrhosis, between January 2000 and December 2017. CP and rCP grades and MELD score were calculated on admission, and the predictive ability in discriminating in-hospital rebleeding and death was compared by area under receiver-operating characteristic (AUROC) curves. RESULTS: During the study period, 403 consecutive adult patients were treated for bleeding esophageal varices of whom 225 were secondary to alcoholic cirrhosis. Twenty-four (10.6%) patients were CP grade A, 88 (39.1%) grade B and 113 (50.2%) grade C on hospital admission. MELD scores ranged from 6 to 40. Thirty-one (13.8%) patients rebleed, and 41 (18.2%) patients died. There was no difference in the discriminatory capacity of the CP (AUROC 0.59, 95% CI 0.50-0.670) and MELD (AUROC 0.62, 95% CI 0.51-0.73) to predict rebleeding (p = 0.72), or between the Child-Pugh (AUROC 0.75, 95% CI 0.71-0.81) and MELD (AUROC 0.71, 95% CI 0.62-0.80) to predict death (p = 0.35). The rCP classification (A-D) had a significantly improved discriminatory capacity (AUROC 0.83 95% CI 0.77-0.89) compared to the CP score (A-C) and MELD to predict death (p = 0.004). CONCLUSION: A recalibrated Child-Pugh score outperforms the original Child-Pugh grade and MELD score in predicting in-hospital death in patients with bleeding esophageal varices secondary to alcoholic cirrhosis.

Derivation, Validation and Application of a Pragmatic Risk Prediction Index for Benchmarking of Surgical Outcomes.

BACKGROUND: Despite the existence of multiple validated risk assessment and quality benchmarking tools in surgery, their utility outside of high-income countries is limited. We sought to derive, validate and apply a scoring system that is both (1) feasible, and (2) reliably predicts mortality in a middle-income country (MIC) context. METHODS: A 5-step methodology was used: (1) development of a de novo surgical outcomes database modeled around the American College of Surgeons' National Surgical Quality Improvement Program (ACS-NSQIP) in South Africa (SA dataset), (2) use of the resultant data to identify all predictors of in-hospital death with more than 90% capture indicating feasibility of collection, (3) use these predictors to derive and validate an integer-based score that reliably predicts in-hospital death in the 2012 ACS-NSQIP, (4) apply the score in the original SA dataset and demonstrate its performance, (5) identify threshold cutoffs of the score to prompt action and drive quality improvement. RESULTS: Following step one-three above, the 13 point Codman's score was derived and validated on 211,737 and 109,079 patients, respectively, and includes: age 65 (1), partially or completely dependent functional status (1), preoperative transfusions ≥4 units (1), emergency operation (2), sepsis or septic shock (2) American Society of Anesthesia score ≥3 (3) and operative procedure (1-3). Application of the score to 373 patients in the SA dataset showed good discrimination and calibration to predict an in-hospital death. A Codman Score of 8 is an optimal cutoff point for defining expected and unexpected deaths. CONCLUSION: We have designed a novel risk prediction score specific for a MIC context. The Codman Score can prove useful for both (1) preoperative decision-making and (2) benchmarking the quality of surgical care in MIC's.

Development and validation of a pancreatic injury mortality score (PIMS) based on 473 consecutive patients treated at a level 1 trauma center.

BACKGROUND: This study sought to develop a pancreatic injury mortality score (PIMS) to identify patients at greatest risk of in-hospital mortality after a major pancreatic injury. METHODS: The study used data from a prospective database of 473 patients treated for pancreatic injuries between January 1990 and December 2015. Two thirds of the patients were assigned to the derivation cohort and one third to the validation cohort. Clinical correlates of in-hospital death were identified and considered in stepwise logistic regression analyses that identified the factors included in the risk index. RESULTS: Five variables, age >55, shock on admission, a vascular injury, number of associated injuries and American Association for the Study of Trauma (AAST) pancreatic injury scale correlated with in-hospital death and were used to calculate PIMS. The final score ROC in the derivation dataset was 0.84 (95% CI 0.79-0.89) and in the validation dataset was 0.91 (95% CI 0.84-0.97), which were comparable (p = 0.1). Finally, cut-off scores were used to generate three risk groups and the rate of mortality within the low (PIMS 0-4), medium (PIMS 5-9), and high risk (PIMS 10-20) groups were not significantly different. The scoring system was tested in a validation cohort and showed good calibration and discrimination for in-hospital mortality. CONCLUSIONS: We have derived and validated the PIMS, a novel organ-specific risk prediction score calculated from five variables for in-hospital mortality following major pancreatic trauma. PIMS is simple, quick and easily understandable, increases clinical risk prediction for patients with complex pancreatic and can be used as a benchmark for survival.

An Online Tool for Global Benchmarking of Risk-Adjusted Surgical Outcomes.

BACKGROUND: Increasing evidence demonstrates significant variation in adverse outcomes following surgery between countries. In order to better quantify these variations, we hypothesize that freely available online risk calculators can be used as a tool to generate global benchmarking of risk-adjusted surgical outcomes. METHODS: This is a prospective cohort study conducted at an academic teaching hospital in South Africa (GSH). Consecutive adult patients undergoing major general or vascular surgery who met the ACS-NSQIP inclusion criteria for a 3-month period were included. Data variables required by the ACS risk calculator were prospectively collected, and patients were followed for 30 days post-surgery for the occurrence of endpoints. Calculating observed-to-expected ratios for ten outcome measures of interest generated risk-adjusted outcomes benchmarked against the ACS-NSQIP consortium. RESULTS: A total of 373 major general and vascular surgery procedures met the inclusion criteria. The GSH operative cohort varied significantly compared to the 2012 ACS-NSQIP database. The risk-adjusted O/E ratios were significant for any complication O/E 1.91 (95 % CI 1.57-2.31), surgical site infections O/E 4.76 (95 % CI 3.71-6.01), renal failure O/E 3.29 (95 % CI 1.50-6.24), death O/E 3.43 (95 % CI 2.19-5.11), and total length of stay (LOS) O/E 3.43 (95 % CI 2.19-5.11). CONCLUSION: Freely available online risk calculators can be utilized as tools for global benchmarking of risk-adjusted surgical outcomes.

Inter-rater reliability of ACS-NSQIP colorectal procedure coding in Canada.

BACKGROUND: The American College of Surgeons National Surgical Quality Improvement Project (ACS-NSQIP) uses Current Procedural Terminology (CPT) codes for risk-adjusted calculations. This study evaluates the inter-rater reliability of coding colorectal resections across Canada by ACS-NSQIP surgical clinical nurse reviewers (SCNR) and its impact on risk predictions. METHODS: SCNRs in Canada were asked to code simulated operative reports. Percent agreement and free-marginal kappa correlation were calculated. The ACS-NSQIP risk calculator was utilized to illustrate its impact on risk prediction. RESULTS: Responses from 44 of 150 (29.3 â€‹%) SCNRs revealed 3 to 6 different codes chosen per case, with agreement ranging from 6.7 â€‹% to 62.3 â€‹%. Free-marginal kappa correlation ranged from moderate agreement (0.53) to high disagreement (-0.17). ACS-NSQIP risk calculator predicted large absolute differences in risk for serious complications (0.2 â€‹%-13.7 â€‹%) and mortality (0.2 â€‹%-6.3 â€‹%). CONCLUSION: This study demonstrated low inter-rater reliability in coding ACS-NSQIP colorectal procedures in Canada among SCNRs, impacting risk predictions.

Acculturation, drinking, and alcohol abuse and dependence among Hispanics in the Texas-Mexico border.

BACKGROUND: Acculturation has been linked to an increased prevalence of alcohol-related problems. However, most of the research has been conducted with Hispanic populations in metropolitan areas of the United States, none of which is on the U.S.-Mexico border. This study examines the association between acculturation, heavy episodic drinking, and DSM-IV alcohol abuse and dependence among Hispanics in the Texas-Mexico border. METHODS: The study used data from a survey conducted (2002 to 2003) along the Texas-Mexico border and included 472 male and 484 female Hispanic adults from El Paso, the Rio Grande Valley, and colonias. Based on the Acculturation Rating Scale for Mexican Americans-II scale, respondents were coded into 4 acculturation categories: "very Mexican oriented,""Mexican bicultural,""Anglo bicultural," or "very Anglo/Anglicized.". RESULTS: Acculturation was related to lower rates of alcohol use disorders among men and a higher frequency of heavy episodic drinking among women. Multivariate analyses indicate that men who report heavy episodic drinking and those who are "very Mexican,""bicultural Mexican," or "bicultural Anglo" are more at higher risk for alcohol abuse and/or dependence compared with "very Anglo/Anglicized" men. For women, acculturation level did not predict alcohol disorders. Statistical analyses included testing for bivariate associations and multivariate logistic regression predicting heavy episodic drinking alcohol abuse or dependence. CONCLUSIONS: This study suggests that acculturation has different effects on drinking for men and women. This finding needs some attention as literature also indicates that women drink more and may develop more alcohol-related problems as they acculturate. This increase in women's drinking is probably because of U.S. society's more liberal norms governing female drinking. The "bimodal" distribution of risk, in which only men in "very Anglo" group are at a lower risk than the others, may be unique to the Border. The association between acculturation and alcohol use disorders does not appear to be linear and the effect of acculturation is not uniform on individuals' drinking behavior.

Alcohol and drug use in rural colonias and adjacent urban areas of the Texas border.

CONTEXT: Little is known about substance use and treatment utilization in rural communities of the United States/Mexico border. PURPOSE: To compare substance use and need and desire for treatment in rural colonias and urban areas of the border. METHODS: Interviews were conducted in 2002-2003 with a random sample of adults living in the lower Rio Grande Valley of Texas, adjacent to the Mexican border. The present analysis compares responses from 400 residents of rural colonias to those of 395 residents of cities and towns in the same geographic region. FINDINGS: While the prevalence of drug use and drug-related problems was similar in both areas, binge drinking and alcohol dependence were higher in rural colonias than in urban areas and remained so after taking demographic and neighborhood variables into account. An increase in illicit drug use and substance-related problems in rural but not urban areas was seen when comparing results from this study with those of a previous survey conducted in 1996. The percentage of adults in potential need of treatment and the percentage motivated to seek it were similar in both urban and rural areas. However, colonia residents were more likely than their urban counterparts to be recent immigrants and to have lower incomes and educational attainment, factors that can increase the barriers they face in getting needed services. CONCLUSIONS: Rural areas are "catching up" with urban areas in problematic substance use. Given the potential barriers to accessing treatment services in rural areas, efforts should be focused on reaching those residents.

Comparative assessment of in-hospital trauma mortality at a South African trauma center and matched patients treated in the United States.

BACKGROUND: The unacceptably high rate of death and disability due to injury in Sub-Saharan Africa is alarming. The objective of this work was to compare mortality rates between severely injured trauma patients at a high-volume trauma center in South Africa with matched patients in the United States. METHODS: Clinical databases from the Groote Schuur Hospital for patients treated in Cape Town, South Africa and the American College of Surgeon's National Trauma Databank for patients treated at large academic trauma centers in the United States were used. Coarsened exact matching identified the most comparable patient populations based on sex, age, intent, injury type, injury mechanism, Injury Severity Score, Glasgow Coma Score, and systolic blood pressure. Conditional logistic regression generated odds ratios for mortality among the entire sample and clinically relevant subgroups. RESULTS: Coarsened exact matching matched 97.9% of the Groote Schuur Hospital patient sample, resulting in 3,206 matched-pairs between the Groote Schuur Hospital and National Trauma Databank cohorts. Conditional logistic regression revealed an odds ratio of mortality of 1.67 (95% confidence interval, 1.10-2.52) for patients at Groote Schuur Hospital compared with matched patients from the National Trauma Databank. Subset analyses revealed significantly increased odds of mortality among patients with blunt injuries (odds ratio 3.40, 95% confidence interval, 1.68-6.88) and patients with a Glasgow Coma Score of 8 or lower (odds ratio 4.33, 95% confidence interval, 2.10-8.95). No statistically significant difference was identified among patients with penetrating injuries or with a Glasgow Coma Score >8 (P value .90 and .39, respectively). CONCLUSION: International comparisons of interhospital variation in risk-adjusted outcomes following trauma can identify opportunities for quality improvement and have the potential to measure the impact of any corrective strategy implemented.

Drug use and risk of HIV/AIDS on the Mexico-USA border: a comparison of treatment admissions in both countries.

This study analyzes trends in treatment admissions and summarizes HIV/AIDS risk factors along the US-Mexican border. Data are presented at the national level and at the state level for states along the border. Client data also are compared for treatment programs located in sister cities on the Texas-Mexico border. These data show that methamphetamine admissions are increasing nationally and methamphetamine use is a major problem in the western states on both sides of the border. Use of Ice (smoked methamphetamine) has increased significantly. Use of crack (smoked cocaine) is a growing problem on the border, and injection is the primary route for using black tar heroin in this area. Each of these drugs is a risk factor, either from drug-influenced risky sexual behaviors or from sharing injection equipment. In addition, the availability of drugs on the border and patterns of risky behaviors among migrants mean that drug users on the border are at risk of HIV/AIDS, and this risk is expected to increase with the spreading methamphetamine epidemic and smoking of crack cocaine. Comparable data on HIV/AIDS are needed for further studies of the relationship of drug use and HIV/AIDS on the border.

Integrated versus parallel treatment of co-occurring psychiatric and substance use disorders.

The study examines 1-year treatment outcomes of 216 individuals with co-occurring severe and persistent mental illness and substance use disorders who were assigned to an integrated or parallel treatment condition. Comparisons indicated that the integrated group achieved greater reductions in the incidence of psychiatric hospitalization and arrest. The results of this study support the enhanced effectiveness of integrated treatment in decreasing the use of higher cost crisis-oriented services in clients with severe mental illness and substance use disorders.

Counselor and client characteristics in mental health versus substance abuse treatment settings providing services for co-occurring disorders.

The study compares counselor and client characteristics of state-funded co-occurring disorder (COPSD) programs in mental health (MH) versus substance abuse (SA) settings. SA counselors more often had graduate degrees and MH counselors rated their knowledge and skills lower on two of nine COPSD best practice principles. MH clients were more frequently diagnosed with schizophrenia, depression, and bipolar disorder, whereas SA clients displayed evidence of greater substance use severity and had higher rates of treatment completion and abstinence at discharge. Results reveal significant implications for workforce development and potential system changes to enhance COPSD services that are unique to each setting.

Assessing health care organizations' ability to implement screening, brief intervention, and referral to treatment.

OBJECTIVES: : To determine if a new measure of organizational readiness for change reflects site and staff role differences when implementing a screening, brief intervention, and referral to treatment (SBIRT) program for alcohol and drug misuse in a healthcare organization. SAMPLE: : One hundred forty-one Community Health Program (CHP) and 45 Emergency Center (EC) respondents completed the survey. METHODS: : Medical and ancillary staff from a Level 1 trauma hospital EC and 3 CHP clinics within a large, urban, publicly funded health-care system were asked to complete the 45-item Medical Organizational Readiness for Change (MORC) survey 5 to 7 months after the start of implementation planning. One-way ANOVAs compared the 4 sites' responses and independent t tests compared the clinical versus administrative staff responses on 8 MORC scales. RESULTS: : There were statistically significant differences between the EC and CHP sites on Need for External Guidance, Pressure to Change, Organizational Readiness to Change, Workgroup Functioning, Work Environment, and Autonomy Support. Clinical and administrative staff differed significantly on Need for External Guidance, Pressure to Change, and Organizational Readiness to Change. When change agents used the MORC data to inform their implementation process, the results were positive. CONCLUSIONS: : Among CHP sites, there were differences in organizational functioning, which were consistent with CHP implementation outcomes. The MORC scales can help planners and change agents understand their organization's current readiness to integrate screening, brief intervention, and referral to treatment services into their medical setting.
