Frailty as a predictor of surgical outcomes in older patients.

BACKGROUND: Preoperative risk assessment is important yet inexact in older patients because physiologic reserves are difficult to measure. Frailty is thought to estimate physiologic reserves, although its use has not been evaluated in surgical patients. We designed a study to determine if frailty predicts surgical complications and enhances current perioperative risk models. STUDY DESIGN: We prospectively measured frailty in 594 patients (age 65 years or older) presenting to a university hospital for elective surgery between July 2005 and July 2006. Frailty was classified using a validated scale (0 to 5) that included weakness, weight loss, exhaustion, low physical activity, and slowed walking speed. Patients scoring 4 to 5 were classified as frail, 2 to 3 were intermediately frail, and 0 to 1 were nonfrail. Main outcomes measures were 30-day surgical complications, length of stay, and discharge disposition. Multiple logistic regression (complications and discharge) and negative binomial regression (length of stay) were done to analyze frailty and postoperative outcomes associations. RESULTS: Preoperative frailty was associated with an increased risk for postoperative complications (intermediately frail: odds ratio [OR] 2.06; 95% CI 1.18-3.60; frail: OR 2.54; 95% CI 1.12-5.77), length of stay (intermediately frail: incidence rate ratio 1.49; 95% CI 1.24-1.80; frail: incidence rate ratio 1.69; 95% CI 1.28-2.23), and discharge to a skilled or assisted-living facility after previously living at home (intermediately frail: OR 3.16; 95% CI 1.0-9.99; frail: OR 20.48; 95% CI 5.54-75.68). Frailty improved predictive power (p < 0.01) of each risk index (ie, American Society of Anesthesiologists, Lee, and Eagle scores). CONCLUSIONS: Frailty independently predicts postoperative complications, length of stay, and discharge to a skilled or assisted-living facility in older surgical patients and enhances conventional risk models. Assessing frailty using a standardized definition can help patients and physicians make more informed decisions.

Impact of preoperative briefings on operating room delays: a preliminary report.

HYPOTHESIS: Preoperative briefings have the potential to reduce operating room (OR) delays through improved teamwork and communication. DESIGN: Pre-post study. SETTING: Tertiary academic center. PARTICIPANTS: Surgeons, anesthesiologists, nurses, and other OR personnel. INTERVENTION: An OR briefings program was implemented after training all OR staff in how to conduct preoperative briefings through in-service training sessions. During the preoperative briefings, the attending surgeon led OR personnel in a 2-minute discussion using a standardized format designed to familiarize caregivers with each other and the operative plan before each surgical procedure. MAIN OUTCOME MEASURES: The OR Briefings Assessment Tool was distributed to OR personnel at the end of each operation. Survey items questioned OR personnel about unexpected delays during each procedure and the relationship between communication breakdowns and delays. Responses were compared before and after the initiation of the preoperative briefings program. RESULTS: The use of preoperative briefings was associated with a 31% reduction in unexpected delays; 36% of OR personnel reported delays in the preintervention period, and 25% reported delays in the postintervention period (P<.04). Among surgeons alone, an 82% reduction in unexpected delays was observed (P<.001). A 19% reduction in communication breakdowns leading to delays was also associated with the use of briefings (P<.006). CONCLUSIONS: Preoperative briefings reduced unexpected delays in the OR by 31% and decreased the frequency of communication breakdowns that lead to delays. Preoperative briefings have the potential to increase OR efficiency and thereby improve quality of care and reduce cost.

Publication bias in surgery: implications for informed consent.

BACKGROUND: Patients consenting for pancreas surgery are often quoted an operative risk of 1% to 3% based on the literature. However, these results are often from centers of excellence, and as a result the literature mortality rates may not be representative or generalizable. METHODS: A MEDLINE search was performed to identify the major studies of pancreaticoduodenectomy (PD) and total pancreatectomy (TP) over a 6-y period (January 1998-December 2003). To obtain a literature-based mortality rate, we performed a meta-analysis of these published series and compared them with actual in-hospital mortality rates based on a representative 20% sample of hospital data in 37 states (the Nationwide Inpatient Sample). The sample included approximately 8 million patient records per year. Literature versus actual mortality rates were compared for the same 6-y period and stratified by academic versus nonacademic medical centers. RESULTS: We identified 16 major studies on PD and TP totaling 3641 patients with an overall mortality rate of 3.2% (range 0%-9.3%). The actual mortality rate based on the Nationwide Inpatient Sample (n = 7604) was 2.4-fold higher than the literature rate (adjusted rate of 7.6% versus 3.2%, P < 0.0001). All literature-based series were published from academic medical centers. By contrast, in the national database, 26.3% of PDs (2003/7604) were performed at nonacademic medical centers with a mortality rate of 11.4% (229/2003). The actual mortality rate at academic medical centers was lower than nonacademic medical centers (6.4% (360/5601), P < 0.0001), but still higher than the literature-based rate of 3.2% (P < 0.0001). CONCLUSIONS: Mortality rates for pancreatic resections in actual practice are 2.4-fold higher than those reported in the literature. Proper informed consent for surgical procedures should include an accurate description of the risks, using actual local and national mortality rates.

Operating room briefings and wrong-site surgery.

BACKGROUND: Wrong-site surgery can be a catastrophic event for a patient, caregiver, and institution. Although communication breakdowns have been identified as the leading cause of wrong-site surgery, the efficacy of preventive strategies remains unknown. This study evaluated the impact of operating room briefings on coordination of care and risk for wrong-site surgery. STUDY DESIGN: We administered a case-based version of the Safety Attitudes Questionnaire (SAQ) to operating room (OR) staff at an academic medical center, before and after initiation of an OR briefing program. Items questioned overall coordination and awareness of the surgical site. Response options ranged from 1 (disagree strongly) to 5 (agree strongly). MANOVA was used to compare caregiver assessments before and after the implementation of briefings, and the percentage of OR staff agreeing or disagreeing with each question was reported. RESULTS: The prebriefing response rate was 85% (306 of 360 respondents), and the postbriefing response rate was 75% (116 of 154). Respondents included surgeons (34.9%), anesthesiologists (14.0%), and nurses (44.4%). Briefings were associated with caregiver perceptions of reduced risk for wrong-site surgery and improved collaboration [F (6,390)=10.15, p < 0.001]. Operating room caregiver assessments of briefing and wrong-site surgery issues improved for 5 of 6 items, eg, "Surgery and anesthesia worked together as a well-coordinated team" (67.9% agreed prebriefing, 91.5% agreed postbriefing, p < 0.0001), and "A preoperative discussion increased my awareness of the surgical site and side being operated on" (52.4% agreed prebriefing, 64.4% agreed postbriefing, p < 0.001). CONCLUSIONS: OR briefings significantly reduce perceived risk for wrong-site surgery and improve perceived collaboration among OR personnel.

Human immunodeficiency virus and hepatitis testing and prevalence among surgical patients in an urban university hospital.

BACKGROUND: Human immunodeficiency virus (HIV), hepatitis B, and hepatitis C represent significant public health problems in an urban community. Early diagnosis and treatment of these infections can improve survival and allow for preventive strategies to reduce further transmission within a community. The aim of this study was to evaluate the surgical setting as a potential opportunity for early diagnosis of HIV, hepatitis B, and hepatitis C among trauma and non-trauma patients. METHODS: We performed a retrospective review of patients presenting for surgery over a 10-year period (July 1994 to July 2004) in an urban, university-based general surgical practice that includes all trauma services, as well as emergency department, inpatient, and outpatient surgical consultations. Data collected included diagnosis, operation, age, race, history of intravenous drug abuse, and HIV, hepatitis B, and hepatitis C test results. RESULTS: Among 2876 patients presenting for surgery, testing for blood-borne pathogens was less likely among trauma patients (21%, 79/380) compared to non-trauma patients (47%, 1183/2496) (P < .001). Among patients tested, the incidence of blood-borne pathogens was similar in the two groups: HIV (26% trauma vs 24% non-trauma, not significant [NS]), hepatitis B (4% trauma vs 3% non-trauma, NS), hepatitis C (33% trauma vs 41% non-trauma, NS), and co-infection with HIV and hepatitis C (18% trauma vs 12% non-trauma, NS). In both groups, blood-borne pathogens were associated with intravenous drug abuse (P < .01). CONCLUSION: HIV, hepatitis B, and hepatitis C are common in an urban community among both trauma and non-trauma surgical patients, although testing is less common among trauma patients. Testing of patients during a surgical admission may represent an excellent opportunity for early disease-specific services and preventive interventions.

Sharpless surgery: a prospective study of the feasibility of performing operations using non-sharp techniques in an urban, university-based surgical practice.

CONTEXT: Percutaneous injuries occur frequently during surgical procedures and represent a significant occupational hazard to operating room personnel. OBJECTIVES: To evaluate the feasibility of performing select general surgical procedures using a combination of non-sharp devices and techniques to replace the conventional use of scalpels and needles. DESIGN, SETTING, AND PARTICIPANTS: Candidate procedures for which sharpless techniques could replace conventional scalpels and suture needles were identified preoperatively in an urban, university-based general surgical practice over a 1-year period (June 2003-June 2004). Non-sharp techniques included monomeric 2-octyl cyanoacrylate adhesive, electrocautery, tissue stapler, and minimally invasive instrumentation. Conventional scalpels and suture needles were readily available and used whenever necessary. MAIN OUTCOME MEASURES: We rated the feasibility of performing specific procedures without sharps. We also documented the rate of overall reversion to sharps during operations on patients that had been identified preoperatively as candidates for sharpless surgery. RESULTS: Of 358 procedures performed in the general surgery university practice, 91 were identified preoperatively as appropriate for sharpless surgery. Of these, 86.8% (79/91) were completed without the use of sharps, including 13/22 (59.1%) open laparotomy procedures, 20/22 (90.9%) laparoscopic procedures, and 46/47 (97.8%) soft tissue procedures. Intraoperative reversion to sharps occurred in 12 cases when deemed necessary by the surgeon. CONCLUSIONS: Select common procedures can be performed entirely with sharpless techniques, eliminating the risk to surgical personnel associated with intraoperative percutaneous injuries.

Prevalence of blood-borne pathogens in an urban, university-based general surgical practice.

OBJECTIVE: To measure the current prevalence of blood-borne pathogens in an urban, university-based, general surgical practice. SUMMARY BACKGROUND DATA: Human immunodeficiency virus (HIV), hepatitis B, and hepatitis C represent significant occupational hazards to the surgeon. While the incidence of these blood-borne pathogens is increasing in the general population, little is known about the current prevalence of these exposures among patients presenting for surgery. METHODS: We studied 709 consecutive operative cases (July 2003 to June 2004) in a university practice that provides all inpatient, emergency department, and outpatient consultative general surgical services. Trauma cases and bedside procedures were excluded. Data collected included HIV, hepatitis B and C test results, type of operation, age, sex, and history of intravenous drug use. RESULTS: Testing for blood-borne pathogens was performed in 53% (N = 373) of 709 patients based on abnormal liver function tests, neutropenia, history of IV drug use, or patient request. Thirty-eight percent of all operations (142/373) were found to involve a blood-borne pathogen when tested: HIV (26%), hepatitis B (4%), hepatitis C (35%), and coinfection with HIV and hepatitis C (17%). Forty-seven percent of men tested positive for at least 1 blood-borne pathogen. Seventy-three different types of operations were performed, ranging from Whipple procedures to amputations. Soft-tissue abscess procedures 48% (34/71) and lymph node biopsies 67% (10/15) (P < 0.01) were most often associated with blood-borne pathogens. Infections were more common among men (P < 0.01), patients 41 to 50 years of age (P < 0.01), and patients with a history of intravenous drug use (P < 0.01). CONCLUSIONS: HIV and hepatitis C infections are common in an urban university general surgical practice, while hepatitis B is less common. In addition, certain operations are associated with significantly increased exposure rates. Given the high incidence of these infections, strategies such as sharpless surgical techniques should be evaluated and implemented to protect surgeons from blood-borne pathogens.
