ABSTRACT

BACKGROUND: The STOPP study (Surgical Treatment Outcomes for Patients with Psychiatric Disorders) analyzed variation in rates and types of major surgery by serious mental illness status among patients treated in the Veterans Health Administration (VA). VA patients are veterans of United States military service who qualify for federal care by reason of disability, special service experiences, or poverty. METHODS: STOPP conducted a secondary data analysis of medical record extracts for seven million VA patients treated Oct 2005-Sep 2009. The retrospective study aggregated inpatient surgery events, comorbid diagnoses, demographics, and postoperative 30-day mortality. RESULTS: Serious mental illness -- schizophrenia, bipolar disorder, posttraumatic stress disorder, or major depressive disorder, was identified in 12 % of VA patients. Over the 4-year study period, 321,131 patients (4.5 %) underwent surgery with same-day preoperative or immediate post-operative admission including14 % with serious mental illness. Surgery patients were older (64 vs. 61 years) and more commonly African-American, unmarried, impoverished, highly disabled (24 % vs 12 % were Priority 1), obese, with psychotic disorder (4.3 % vs 2.9 %). Among surgery patients, 3.7 % died within 30 days postop. After covariate adjustment, patients with pre-existing serious mental illness were relatively less likely to receive surgery (adjusted odds ratios 0.4-0.7). CONCLUSIONS: VA patients undergoing major surgery appeared, in models controlling for comorbidity and demographics, to disproportionately exclude those with serious mental illness. While VA preferentially treats the most economically and medically disadvantaged veterans, the surgery subpopulation may be especially ill, potentially warranting increased postoperative surveillance.

ABSTRACT

BACKGROUND: Anticipating poor recovery due to impaired self-management and appointment-keeping, clinicians may consider serious mental illness (SMI) a significant concern in organ transplantation. However, little empirical evidence exists regarding posttransplantation outcomes for patients with SMI. METHODS: This study analyzed health services data to evaluate posttransplantation 3-year survival by SMI status in a nationwide cohort of patients in the Veterans Health Administration (VHA). RESULTS: A total of 960 recipients of solid organ or bone marrow transplants were identified from Veterans Health Administration administrative data extracts for fiscal years 2006 to 2009. Of these, 164 (17%) had an SMI diagnosis before transplantation (schizophrenia, posttraumatic stress, major depressive, and bipolar disorders); 301 (31%) had some other mental illness diagnosis (such as anxiety, adjustment reactions, or substance abuse); and 495 (52%) had no mental health diagnosis. Twenty-two patients (2%) required retransplantation and 208 patients (22%) died during follow-up. Data on whether these were primary or repeat transplantations were unavailable. Rates of attendance at postoperative outpatient visits and number of months for which immunosuppressive drugs fills were recorded were similar among mental illness groups, as were rates of diagnosed immunological rejection. Three-year mortality was equivalent among mental health groups: no mental health (19%) versus other mental illness (23%) versus SMI (27%; χ(2) = 5.11; df = 2; P = .08). In adjusted survival models, no effect of mental health status was observed. CONCLUSIONS: Serious mental illness diagnosis does not appear to be associated with adverse transplantation outcomes over the first 3 years; however, a potentially diverging survival curve may portend higher mortality at 5 years.

ABSTRACT

OBJECTIVE: To estimate 1-year mortality risk associated with preoperative serious mental illness (SMI) as defined by the Veterans Health Administration (schizophrenia, bipolar disorder, posttraumatic stress disorder [PTSD], major depression) following nonambulatory cardiac or vascular surgical procedures compared to patients without SMI. Cardiac/vascular operations were selected because patients with SMI are known to be at elevated risk of cardiovascular disease. METHOD: Retrospective analysis of system-wide data from electronic medical records of patients undergoing nonambulatory surgery (inpatient or day-of-surgery admission) October 2005-September 2009 with 1-year follow-up (N=55,864; 99% male; <30 days of postoperative hospitalization). Death was hypothesized to be more common among patients with preoperative SMI. RESULTS: One in nine patients had SMI, mostly PTSD (6%). One-year mortality varied by procedure type and SMI status. Patients had vascular operations (64%; 23% died), coronary artery bypass graft (26%; 10% died) or other cardiac operations (11%; 15%-18% died). Fourteen percent of patients with PTSD died, 20% without SMI and 24% with schizophrenia, with other groups intermediate. In multivariable stratified models, SMI was associated with increased mortality only for patients with bipolar disorder following cardiac operations. Bipolar disorder and PTSD were negatively associated with death following vascular operations. CONCLUSIONS: SMI is not consistently associated with postoperative mortality in covariate-adjusted analyses.

ABSTRACT

Stress fractures are a common overuse problem among military trainees resulting in preventable morbidity, prolonged training, and long-term disability following military service. Femoral neck stress fractures (FNSFs) account for 2% of all stress fractures but result in disproportionate burden in terms of cost and convalescence. The purpose of this study was to describe and investigate FNSF in U.S. Air Force basic trainees and to present new data on risks factors for developing FNSF. We examined 47 cases of FNSF occurring in Air Force basic trainees between 2008 and 2011 and 94 controls using a matched case-control model. Analysis with t tests and conditional logistic regression found the risk of FNSF was not associated with body mass index or abdominal circumference. Female gender (p < 0.001) and slower run time significantly increased risk of FNSF (1.49 OR, p < 0.001; 95% CI 1.19-1.86). A greater number of push-up and sit-up repetitions significantly reduced risk of FNSF (0.55 OR, p = 0.03; 95% CI 0.32-0.93; 0.62 OR, p = 0.04; 95% CI 0.4-0.98) for females. In this study body mass index was not correlated with FNSF risk; however, physical fitness level on arrival to training and female gender were significantly associated with risk of FNSF.

ABSTRACT

CONTEXT: Postoperative paralytic ileus (POI) has profound clinical consequences because it represents a substantial burden on both patients and health care resources. OBJECTIVE: To determine the knowledge base regarding POI in the radical cystectomy (RC) population with an emphasis on preventive measures and risk factors. EVIDENCE ACQUISITION: A systematic literature search of Medline (1966 to February 2011) and a study review were conducted. Eligible studies explicitly reported the incidence of POI and/or at least two quantitative measures of gastrointestinal recovery. EVIDENCE SYNTHESIS: The search identified 727 relevant articles; 77 met eligibility criteria, comprising 13 793 patients. Of these, 21 used explicit definitions of POI, and they varied widely. Across studies, the incidence of POI ranged from 1.58% to 23.5%. Possible risk factors for POI included increasing age and body mass index. Seventeen studies reported effects of an intervention on POI: 3 randomized controlled studies, 11 observational cohort studies with concurrent comparison, and 3 observational cohort studies with nonconcurrent comparison. Gum chewing was associated with shortened times to flatus (2.4 vs 2.9 d; p<0.0001) and bowel movement (BM) (3.2 vs 3.9 d; p<0.001) in one observational cohort study (n=102); omission of a postoperative nasogastric tube (NGT) was associated with shorter time to flatus (4.21 vs 5.33 d; p=0.0001) and shorter length of stay (14.4 vs 19.1 d; p=0.001) in one observational cohort study (n=430); and the routine use of bowel preparation was associated with an increased incidence of POI (5% vs 19%) in another series (n=86). Additionally, readaptation of the dorsolateral peritoneal layer was shown to shorten times to flatus (p=0.016) and times to BM (p=0.011) in one randomized controlled study (n=200). CONCLUSIONS: The incidence/definition of POI after RC is highly variable. An improved reporting strategy is needed to identify true incidence and risk factors, and to guide future research for both potential preventive and therapeutic interventions.

ABSTRACT

To examine equity in one aspect of care provision in the Veterans Health Administration, this study analyzed factors associated with receipt of coronary artery bypass graft (CABG), vascular, hip/knee, or digestive system surgeries during FY2006-2009. A random sample of patients (N = 317, 072) included 9% with depression, 17% African-American patients, 5% Hispanics, and 5% women. In the four-year followup, 18,334 patients (6%) experienced surgery: 3,109 hip/knee, 3,755 digestive, 1,899 CABG, and 11,330 vascular operations. Patients with preexisting depression were less likely to have surgery than nondepressed patients (4% versus 6%). In covariate-adjusted analyses, minority patients were slightly less likely to receive vascular operations compared to white patients (Hispanic OR = 0.88, P < .01; African-American OR = 0.93, P < .01) but more likely to undergo digestive system procedures. Some race-/ethnicity-related disparities of care for cardiovascular disease may persist for veterans using the VHA.

ABSTRACT

OBJECTIVE: Veterans from the wars in Afghanistan and Iraq (OEF/OIF) report high rates of mental distress especially affective disorders. Ensuring continuity of care across institutions is a priority for both the Department of Defense (DoD) and the Veterans Health Administration (VHA), yet this process is not monitored nor are medical records integrated. This study assessed transition from DoD to VHA and subsequent psychiatric care of service members traumatically injured in OEF/OIF. METHODS: Inpatients at a DoD trauma treatment facility discharged in FY02-FY06 (n=994) were tracked into the VHA via archival data (n=216 OEF/OIF veterans). Mental health utilization in both systems was analyzed. RESULTS: VHA users were 9% female, 15% Hispanic; mean age 32 (SD=10; range 19-59). No DoD inpatients received diagnoses of post-traumatic stress disorder (PTSD); 21% had other mental health diagnoses, primarily drug abuse. In the VHA, 38% sought care within 6 months of DoD discharge; 75% within 1 year. VHA utilization increased over time, with 88-89% of the transition cohort seeking care in FY07-FY09. Most accessed VHA mental health services (81%) and had VHA psychiatric diagnoses (71%); half met criteria for depression (27%) or PTSD (38%). Treatment retention through FY09 was significantly greater for those receiving psychiatric care: 98% vs 62% of those not receiving psychiatric care (x(2)=53.3; p<.001). LIMITATIONS: DoD outpatient data were not available. The study relied on administrative data. CONCLUSIONS: Although physical trauma led to hospitalization in the DoD, high rates of psychiatric disorders were identified in subsequent VHA care, suggesting delay in development or recognition of psychiatric problems.

ABSTRACT

OBJECTIVES: Assess glycemic monitoring and follow-up. DESIGN: Retrospective study using administrative data (October 2001-September 2005). SETTING: Veterans Health Administration. PARTICIPANTS: A nationwide sample of 39,226 outpatients aged 50 years or older with schizophrenia. Patients had no diagnosis or medications for diabetes at baseline. MEASUREMENTS: Hemoglobin A1c tests; blood glucose tests with same-day low-density lipoprotein to approximate fasting glucose. Glycemic tests were combined to indicate a) prediabetic dysglycemia (100-125 mg/dL proxy fasting glucose or 5.8%-6.4% hemoglobin A1c) and b) diabetic dysglycemia (≥126 proxy fasting glucose or ≥6.5% A1c). RESULTS: Approximately one-third of patients (32%; 12,587) had proxy fasting blood glucose or A1c tests in 2002; multiple tests were rare. The proportion tested increased to 40% by 2005. Test results suggested prediabetic dysglycemia for 5,345 tested patients (42% of those tested) and diabetic dysglycemia for 1,287 tested patients (10%) at baseline. In multivariate regression models, glycemic testing was associated with dyslipidemia, hypertension, and younger age. Dysglycemia was associated with hypertension, dyslipidemia, and older age. Follow-up treatment/diagnosis of diabetes occurred for 8% of patients (11% of those tested) and was associated with baseline dysglycemia, hypertension, and younger age. Mortality (15% during the 4-year study) was higher among untested and untreated patients. CONCLUSIONS: Dysglycemia was prevalent among older patients with schizophrenia, although monitoring and follow-up were uncommon. Follow-up treatment correlated with survival. Despite evident utility of testing, few at-risk patients with schizophrenia were adequately monitored, diagnosed, or treated for dysglycemia.

ABSTRACT

BACKGROUND: Randomized controlled trials and meta-analyses provide conflicting guidance on the role of beta-adrenergic receptor blockers (beta-blockers) in reducing perioperative complications. We hypothesize that variability in trial results may be due in part to heterogeneous properties of beta-blockers. First, we propose that the extent of beta-blocker metabolism by cytochrome P-450 and the time available to titrate the dosage before surgery (titration time) may interact; dependence on P-450 may be most harmful when titration time is short. Second, beta-blockers vary in their selectivity for the beta-1 receptor and reduced selectivity may contribute to cerebral ischemia. METHODS: We used meta-analysis and meta-regression of existing trials to explore the role of these pharmacological properties. RESULTS: We found that both of these pharmacological factors are significantly associated with reduced efficacy of beta-blockers. CONCLUSIONS: Pharmacological properties of beta-blockers may contribute to heterogeneous trial results. Many trials have used metoprolol, which is extensively metabolized by cytochrome P450 and is less selective for the beta-1 receptor. For these two reasons, the efficacy of metoprolol to prevent perioperative cardiac complications should be compared with the efficacy of other beta-blockers.

ABSTRACT

BACKGROUND: Patients with schizophrenia have difficulty managing their medical healthcare needs, possibly resulting in delayed treatment and poor outcomes. We analyzed whether patients reduced primary care use over time, differentially by diagnosis with schizophrenia, diabetes, or both schizophrenia and diabetes. We also assessed whether such patterns of primary care use were a significant predictor of mortality over a 4-year period. METHODS: The Veterans Healthcare Administration (VA) is the largest integrated healthcare system in the United States. Administrative extracts of the VA's all-electronic medical records were studied. Patients over age 50 and diagnosed with schizophrenia in 2002 were age-matched 1:4 to diabetes patients. All patients were followed through 2005. Cluster analysis explored trajectories of primary care use. Proportional hazards regression modelled the impact of these primary care utilization trajectories on survival, controlling for demographic and clinical covariates. RESULTS: Patients comprised three diagnostic groups: diabetes only (n = 188,332), schizophrenia only (n = 40,109), and schizophrenia with diabetes (Scz-DM, n = 13,025). Cluster analysis revealed four distinct trajectories of primary care use: consistent over time, increasing over time, high and decreasing, low and decreasing. Patients with schizophrenia only were likely to have low-decreasing use (73% schizophrenia-only vs 54% Scz-DM vs 52% diabetes). Increasing use was least common among schizophrenia patients (4% vs 8% Scz-DM vs 7% diabetes) and was associated with improved survival. Low-decreasing primary care, compared to consistent use, was associated with shorter survival controlling for demographics and case-mix. The observational study was limited by reliance on administrative data. CONCLUSION: Regular primary care and high levels of primary care were associated with better survival for patients with chronic illness, whether psychiatric or medical. For schizophrenia patients, with or without comorbid diabetes, primary care offers a survival benefit, suggesting that innovations in treatment retention targeting at-risk groups can offer significant promise of improving outcomes.

ABSTRACT

OBJECTIVE: To determine the knowledge base on clinical outcomes of surgery among persons diagnosed with serious mental illness. BACKGROUND: Despite a burgeoning literature during the last 20 years regarding perioperative risk management, little is known about intraoperative and postoperative complications among patients with schizophrenia and other serious mental illnesses. METHODS: A systematic literature search of Medline (1966-August 2007) and review of studies was conducted. Eligible studies were of any design with at least 10 patients diagnosed with serious mental illness, reporting perioperative medical, surgical, or psychiatric complications. RESULTS: The search identified 1367 potentially relevant publications; only 12 met eligibility criteria. Of 10 studies of patients with schizophrenia, 9 had fewer than 100 patients, whereas one large retrospective study reported higher rates of postoperative complications among 466 schizophrenia patients compared with 338,257 controls. These studies suggest that patients with schizophrenia, compared with those without mental illness, may have higher pain thresholds, higher rates of death and postoperative complications, and differential outcomes (eg, confusion, ileus) by anesthetic technique. Two studies evaluated outcomes in patients with major depressive disorder and found higher rates of postoperative delirium and postoperative confusion. Both schizophrenia and depression patients experienced more postoperative confusion or delirium when psychiatric medications were discontinued preoperatively. We identified no studies of perioperative outcomes in patients with bipolar or posttraumatic stress disorder. CONCLUSIONS: There are few studies of perioperative outcomes in patients with serious mental illness. Future research should assess surgical risks among patients with serious psychiatric conditions using rigorous methods and well-defined clinical outcomes.

ABSTRACT

Cancer disproportionately afflicts older patients, with 56% of incident diagnoses and 71% of deaths occurring in this population. Yet little is known about the "oldest of the old", oncology patients underrepresented in clinical trials. We examined elderly veterans diagnosed with lung, colorectal, prostate or head-neck cancer in 2005 (n=194,797), analyses comparing treatment receipt by age group, 70-84 versus 85-115. Treatment was more common among younger elders, including surgery (1.3% versus 0.6%), chemotherapy (2.1% versus 0.8%) and radiation (1.7% versus 0.7%). Differences were sharper for certain cancers, e.g., chemotherapy for lung (9.0% versus 2.9%), or colorectal surgery (5.8% versus 3.4%). Cancer prevalence is high among elders yet treatment rates appear extremely low, despite evidence of well-tolerated treatment. Toxicity concerns and comorbidities may inhibit pursuit of definitive treatment. As we reconcile definitions of 'elderly' with appropriate treatment options, compassionate care requires identifying geriatric oncology guidelines that improve survival and quality of life.

ABSTRACT

The incidence of heparin-induced thrombocytopenia in human immunodeficiency virus (HIV)-infected inpatients was compared with that in a control group that was not known to be infected with HIV in a retrospective cohort study. HIV-infected patients receiving heparin therapy, especially unfractionated heparin therapy, were at increased risk of developing heparin-induced thrombocytopenia, compared with HIV-uninfected patients.

ABSTRACT

Postoperative pulmonary complications play an important role in the risk for patients undergoing noncardiothoracic surgery. Postoperative pulmonary complications are as prevalent as cardiac complications and contribute similarly to morbidity, mortality, and length of stay. Pulmonary complications may even be more likely than cardiac complications to predict long-term mortality after surgery. The purpose of this guideline is to provide guidance to clinicians on clinical and laboratory predictors of perioperative pulmonary risk before noncardiothoracic surgery. It also evaluates strategies to reduce the perioperative pulmonary risk and focuses on atelectasis, pneumonia, and respiratory failure. The target audience for this guideline is general internists or other clinicians involved in perioperative management of surgical patients. The target patient population is all adult persons undergoing noncardiothoracic surgery.

ABSTRACT

BACKGROUND: The importance of clinical risk factors for postoperative pulmonary complications and the value of preoperative testing to stratify risk are the subject of debate. PURPOSE: To systematically review the literature on preoperative pulmonary risk stratification before noncardiothoracic surgery. DATA SOURCES: MEDLINE search from 1 January 1980 through 30 June 2005 and hand search of the bibliographies of retrieved articles. STUDY SELECTION: English-language studies that reported the effect of patient- and procedure-related risk factors and laboratory predictors on postoperative pulmonary complication rates after noncardiothoracic surgery and that met predefined inclusion criteria. DATA EXTRACTION: The authors used standardized abstraction instruments to extract data on study characteristics, hierarchy of research design, study quality, risk factors, and laboratory predictors. DATA SYNTHESIS: The authors determined random-effects pooled estimate odds ratios and, when appropriate, trim-and-fill estimates for patient- and procedure-related risk factors from studies that used multivariable analyses. They assigned summary strength of evidence scores for each factor. Good evidence supports patient-related risk factors for postoperative pulmonary complications, including advanced age, American Society of Anesthesiologists class 2 or higher, functional dependence, chronic obstructive pulmonary disease, and congestive heart failure. Good evidence supports procedure-related risk factors for postoperative pulmonary complications, including aortic aneurysm repair, nonresective thoracic surgery, abdominal surgery, neurosurgery, emergency surgery, general anesthesia, head and neck surgery, vascular surgery, and prolonged surgery. Among laboratory predictors, good evidence exists only for serum albumin level less than 30 g/L. Insufficient evidence supports preoperative spirometry as a tool to stratify risk. LIMITATIONS: For certain risk factors and laboratory predictors, the literature provides only unadjusted estimates of risk. Prescreening, variable selection algorithms, and publication bias limited reporting of risk factors among studies using multivariable analysis. CONCLUSIONS: Selected clinical and laboratory factors allow risk stratification for postoperative pulmonary complications after noncardiothoracic surgery.

ABSTRACT

BACKGROUND: Postoperative pulmonary complications are as frequent and clinically important as cardiac complications in terms of morbidity, mortality, and length of stay. However, there has been much less research and no previous systematic reviews of the evidence of interventions to prevent pulmonary complications. PURPOSE: To systematically review the literature on interventions to prevent postoperative pulmonary complications after noncardiothoracic surgery. DATA SOURCES: MEDLINE English-language literature search, 1 January 1980 through 30 June 2005, plus bibliographies of retrieved publications. STUDY SELECTION: Randomized, controlled trials (RCTs); systematic reviews; or meta-analyses that met predefined inclusion criteria. DATA EXTRACTION: Using standardized forms, the authors abstracted data on study methods, quality, intervention and control groups, patient characteristics, surgery, postoperative pulmonary complications, and adverse events. DATA SYNTHESIS: The authors qualitatively synthesized, without meta-analysis, evidence from eligible studies. Good evidence (2 systematic reviews, 5 additional RCTs) indicates that lung expansion interventions (for example, incentive spirometry, deep breathing exercises, and continuous positive airway pressure) reduce pulmonary risk. Fair evidence suggests that selective, rather than routine, use of nasogastric tubes after abdominal surgery (2 meta-analyses) and short-acting rather than long-acting intraoperative neuromuscular blocking agents (1 RCT) reduce risk. The evidence is conflicting or insufficient for preoperative smoking cessation (1 RCT), epidural anesthesia (2 meta-analyses), epidural analgesia (6 RCTs, 1 meta-analysis), and laparoscopic (vs. open) operations (1 systematic review, 1 meta-analysis, 2 additional RCTs), although laparoscopic operations reduce pain and pulmonary compromise as measured by spirometry. While malnutrition is associated with increased pulmonary risk, routine total enteral or parenteral nutrition does not reduce risk (1 meta-analysis, 3 additional RCTs). Enteral formulations designed to improve immune status (immunonutrition) may prevent postoperative pneumonia (1 meta-analysis, 1 additional RCT). LIMITATIONS: The overall quality of the literature was fair: Ten of 20 RCTs and 6 of 11 systematic reviews were good quality. CONCLUSIONS: Few interventions have been shown to clearly or possibly reduce postoperative pulmonary complications.

ABSTRACT

BACKGROUND: Elders undergo approximately 40% of more than 1 million major abdominal operations annually. Yet evidence about recovery to preoperative levels of functional independence is limited. This study details course and predictors of functional recovery after elective major abdominal operations in the elderly. STUDY DESIGN: This was a prospective cohort of 372 consecutive patients, 60 years old or more, enrolled from surgeons in private practice and two university-affiliated hospitals, assessed preoperatively and postoperatively at 1, 3, and 6 weeks, 3 and 6 months, using self-report and performance-based measures (Activities of Daily Living [ADL], Instrumental Activities of Daily Living [IADL], Medical Outcomes Study Short Form-36 Physical Component and Mental Component Scales [PCS, MCS], Geriatric Depression Scale [GDS], Folstein Mini-Mental State Exam [MMSE], timed walk, functional reach, hand grip strength). RESULTS: Mean age was 69 +/- 6 years with 56% men, 47% nonHispanic Caucasian, and 42% Mexican American; hospital distribution was 49% private, 51% university-affiliated. Maximum functional declines (95% CI) occurred 1 week postoperatively: ADL, 2.8 points (2.4 to 3.2); IADL, 7.6 points (7 to 8.3); SF-36 PCS, 6.5 points (5.4 to 7.6); Mini-Mental State Exam, 0.5 points (0.2 to 0.7); timed walk, 6.8 seconds (5.2 to 8.4); functional reach, 1.7 inches (1.2 to 2.2); grip strength, 2 kilograms (1.3 to 2.7) (p < 0.001 for all). SF-36 mental component scale and Geriatric Depression Scale scores did not worsen. Mean recovery times were: Mini-Mental State Exam, 3 weeks; timed walk, 6 weeks; ADL, SF-36 PCS, and functional reach, 3 months; and IADL, 6 months. Mean grip strength did not return to preoperative status by 6 months. The incidence of persistent disability at 6 months, compared with preoperative status, was: ADL, 9%; IADL, 19%; PCS, 16%; mental component scale, 17%; timed walk, 39%; functional reach, 58%; and grip strength, 52%. Potentially modifiable independent predictors of ADL and IADL recovery were preoperative physical conditioning and depression plus serious postoperative complications. CONCLUSIONS: The clinical course of functional recovery varied across different measures. Protracted disability at 6 months after operation was substantial. Several potentially modifiable factors consistently predicted recovery.

ABSTRACT

BACKGROUND: The benefits and indications for blood transfusion are controversial. One possible reason to transfuse is to improve functional recovery after major surgery. However, the data linking improved function with higher Hb concentration are limited. STUDY DESIGN AND METHODS: A: retrospective cohort study was performed in 5793 patients at least 60 years old undergoing hip fracture repair at 20 academic and community hospitals. The primary outcome was distance walked at the time of discharge from the hospital. The mean postoperative Hb concentration was the main exposure variable and was defined as the average value from Day 1 after surgery to discharge. We used robust regression to assess the association between postoperative Hb level with distance walked, controlling for other preoperative variables that could influence functional recovery. RESULTS: On bivariate analysis, the predicted distance walked at discharge in feet (95% CI) increased with higher Hb levels (7 g/dL, 56 feet [42-70]; 8 g/dL, 61 feet [54-68]; 9 g/dL, 67 feet [64-70]; 10 g/dL, 74 feet [72-77]; 11 g/dL, 83 feet [80-85]; 12 g/dL, 92 feet [87-96]). After adjustment for other factors associated with ability to walk, higher average postoperative Hb level was independently associated with walking greater distance (p < 0.001). CONCLUSIONS: Higher postoperative Hb level may improve functional recovery after hip fracture repair. If confirmed with clinical trials, this finding would provide a rationale to maintain higher Hb concentrations in elderly patients recovering from surgery.
