Spine Surgery and Preoperative Hemoglobin, Hematocrit, and Hemoglobin A1c: A Systematic Review.

ABSTRACT:

Study design

Systematic review.

Objectives

Synthesize previous studies evaluating clinical utility of preoperative Hb/Hct and HbA1c in patients undergoing common spinal procedures: anterior cervical discectomy and fusion (ACDF), posterior cervical fusion (PCF), posterior lumbar fusion (PLF), and lumbar decompression (LD).

Methods

We queried PubMed, Embase, Cochrane Library, and Web of Science for literature on preoperative Hb/Hct and HbA1c and post-operative outcomes in adult patients undergoing ACDF, PCF, PLF, or LD surgeries.

Results

Total of 4,307 publications were assessed. Twenty-one articles met inclusion criteria.

Pcf and acdf

Decreased preoperative Hb/Hct were significant predictors of increased postoperative morbidity, including return to operating room, pulmonary complications, transfusions, and increased length of stay (LOS). For increased HbA1c, there was significant increase in risk of postoperative infection and cost of hospital stay.

Plf

Decreased Hb/Hct was reported to be associated with increased risk of postoperative cardiac events, blood transfusion, and increased LOS. Elevated HbA1c was associated with increased risk of infection as well as higher visual analogue scores (VAS) and Oswestry disability index (ODI) scores.

Ld

LOS and total episode of care cost were increased in patients with preoperative HbA1c elevation.

Conclusion

In adult patients undergoing spine surgery, preoperative Hb/Hct are clinically useful predictors for postoperative complications, transfusion rates, and LOS, and HbA1c is predictive for postoperative infection and functional outcomes. Using Hct values <35-38% and HbA1c >6.5%-6.9% for identifying patients at higher risk of postoperative complications is most supported by the literature. We recommend obtaining these labs as part of routine pre-operative risk stratification.

Project description:ImportancePreoperative hyperglycemia is associated with adverse postoperative outcomes among patients who undergo surgery. Whether preoperative hemoglobin A1c (HbA1c) or postoperative glucose levels are more useful in predicting adverse events following surgery is uncertain in the current literature.ObjectiveTo examine the use of preoperative HbA1c and early postoperative glucose levels for predicting postoperative complications and readmission.Design, setting, and participantsIn this observational cohort study, inpatient gastrointestinal surgical procedures performed at 117 Veterans Affairs hospitals from 2007 to 2014 were identified, and cases of known infection within 3 days before surgery were excluded. Preoperative HbA1c levels were examined as a continuous and categorical variable (<5.7%, 5.7%-6.5%, and >6.5%). A logistic regression modeled postoperative complications and readmissions with the closest preoperative HbA1c within 90 days and the highest postoperative glucose levels within 48 hours of undergoing surgery.Main outcomes and measuresPostoperative complications and 30-day unplanned readmission following discharge.ResultsOf 21 541 participants, 1193 (5.5%) were women, and the mean (SD) age was 63.7 (10.6) years. The cohort included 23 094 operations with measurements of preoperative HbA1c levels and postoperative glucose levels. The complication and 30-day readmission rates were 27.2% and 14.7%, respectively. In logistic regression models adjusting for HbA1c, postoperative glucose levels, postoperative insulin use, diabetes, body mass index (calculated as weight in kilograms divided by height in meters squared), and other patient and procedural factors, peak postoperative glucose levels of more than 250 mg/dL were associated with increased 30-day readmissions (odds ratio, 1.18; 95% CI, 0.99-1.41; P = .07). By contrast, a preoperative HbA1c of more than 6.5% was associated with decreased 30-day readmissions (odds ratio, 0.85; 95% CI, 0.74-0.96; P = .01). As preoperative HbA1c increased, the frequency of 48-hour postoperative glucose checks increased (4.92, 6.89, and 9.71 for an HbA1c <5.7%, 5.7%-6.4%, and >6.5%, respectively; P < .001). Patients with a preoperative HbA1c of more than 6.5% had lower thresholds for postoperative insulin use.Conclusions and relevanceEarly postoperative hyperglycemia was associated with increased readmission, but elevated preoperative HbA1c was not. A higher preoperative HbA1c was associated with increased postoperative glucose level checks and insulin use, suggesting that heightened postoperative vigilance and a lower threshold to treat hyperglycemia may explain this finding.

Project description:Study Design Systematic review. Objective To examine the relationship between the patient's preoperative expectations and short-term postoperative satisfaction and functional outcome in lumbar spine surgery. Methods The Medline, Embase, and Cochrane databases were queried using a predefined search algorithm to identify all lumbar spine studies analyzing the influence of preoperative expectations on postoperative satisfaction and functional outcome. Two independent reviewers and a third independent mediator reviewed the literature and performed study screening, selection, methodological assessment, and data extraction using an objective protocol. Results Of 444 studies identified, 13 met the inclusion criteria. Methodological quality scores ranged from 59 to 100% with the greatest variability in defining patient characteristics and the methods of assessing patient expectations. Patient expectations were assessed in 22 areas, most frequently back and leg pain expectations and general expectations. Functional outcome was assessed by 13 tools; the most common were the visual analog scale, Oswestry Disability Index (ODI), and Short Form Health Survey (SF-36). Positive expectations for symptomatology, activity, general health, and recovery correlated with satisfaction. General expectations correlated with higher SF-36 Physical Subcomponent scores, better global function, and lower ODI outcome. Conclusions on the influence of the expectations for pain were limited due to the study heterogeneity, but the evidence suggests a positive correlation between the expectation and outcome for back and leg pain. Conclusions Positive expectations correlated significantly with short-term postoperative satisfaction and functional outcome, including higher SF-36 scores, earlier return to work, and decreased ODI scores. Future expectation-based investigations will benefit from implementation of the standardized methods of expectation, satisfaction, and outcome analysis discussed herein.

Project description:BackgroundDiabetes mellitus is a chronic burden, with a prevalence that is increasing worldwide. Telemetric interventions have attracted great interest and may provide effective new therapeutic approaches for improving type 2 diabetes mellitus (T2DM) care.ObjectiveThe objective of this study was to analyze the clinical effectiveness of telemetric interventions on glycated hemoglobin A1c (HbA1c) specifically and T2DM management generally in a systematic meta-review.MethodsA systematic literature search was performed in PubMed, CINAHL, Cochrane Library, Web of Science Core Collection, and EMBASE databases from January 2008 to April 2020. Studies that addressed HbA1c, blood pressure, fasting blood glucose, BMI, diabetes-related and health-related quality of life, cost-effectiveness, time savings, and the clinical effectiveness of telemetric interventions were analyzed. In total, 73 randomized controlled trials (RCTs), 10 systematic reviews/meta-analyses, 9 qualitative studies, 2 cohort studies, 2 nonrandomized controlled studies, 2 observational studies, and 1 noncontrolled intervention study were analyzed.ResultsOverall, 1647 citations were identified. After careful screening, 99 studies (n=15,939 patients; n=82,436 patient cases) were selected by two independent reviewers for inclusion in the review. Telemetric interventions were categorized according to communication channels to health care providers: (1) "real-time video" interventions, (2) "real-time audio" interventions, (3) "asynchronous" interventions, and (4) "combined" interventions. To analyze changes in HbA1c, suitable RCTs were pooled and the average was determined. An HbA1c decrease of -1.15% (95% CI -1.84% to -0.45%), yielding an HbA1c value of 6.95% (SD 0.495), was shown in studies using 6-month "real-time video" interventions.ConclusionsTelemetric interventions clearly improve HbA1c values in both the short term and the long term and contribute to the effective management of T2DM. More studies need to be done in greater detail.
