Quality Improvement: A Primer for Plastic Surgeons.

SUMMARY: It is the duty of all health care workers to improve the quality of care and patient outcomes. Quality improvement is a component of health policy required by residency accrediting bodies and is a mandatory component of postgraduate medical education. It is imperative for plastic surgeons to develop skills in quality improvement to ensure that they can cope with increased patient volumes while ensuring that their patients have access to care that is safe, equitable, effective, efficient, timely, and patient-centered. This article discusses techniques and tools often used in quality improvement. Challenges encountered with quality improvement initiatives are discussed, and recommendations on how to handle them as they occur are offered. This primer provides a foundation for plastic surgeons and their staff to guide their quality improvement efforts. A hypothetical quality improvement project is used as an example to illustrate the concepts of quality improvement in this primer.

Is our initial evaluation of patients admitted for syncope guideline-directed and cost-effective?

INTRODUCTION: Recent American College of Cardiology and European Society of Cardiology guidelines for syncope evaluation help distinguish high-cardiac risk patients from those with low-risk orthostatic and neurogenic syncope. Inpatient evaluation is recommended if at least one high-risk feature is present. OBJECTIVE: To assess guideline adherence and its impact on hospitalization in patients who presented with syncope before and after the introduction of guideline-based syncope protocol in the emergency department (ED). METHODS: All adult patients admitted to general medicine from the ED with the primary diagnosis of syncope in the months of October 2016 and October 2018 (before and after the introduction of syncope protocol in 2017). Electronic charts were retrospectively reviewed for high-risk cardiac features and orthostatic blood pressure measurement. RESULTS: Sixty patients were admitted for syncope in October 2016 (n = 32) and October 2018 (n = 28), out of which 33 (55%) were female and 47 (78.3%) were over age 50. Forty-five patients had at least one high-risk feature. Excluding one patient with an alternate diagnosis at discharge, 14 out of 60 patients (23.3%) admitted for syncope did not have any high-risk feature. Orthostatic blood pressure was measured in 3 patients (5%) in the ED and 27 patients (45%) later in the hospitalization. Six out of eight patients with implanted cardioverter-defibrillator or pacemaker had their devices interrogated. After the introduction of syncope protocol, there was an improvement in the proportion of high-risk patients admitted [68.7% (22/32) in October 2016 vs. 82.1% (23/28) in October 2018]. CONCLUSION: Utilizing syncope protocol in the ED may improve guideline adherence, direct appropriate disposition, and reduce healthcare expenses.

Severe cholestatic hyperbilirubinaemia secondary to thyrotoxicosis complicated with bile cast nephropathy treated with plasma exchange and haemodialysis.

Thyrotoxicosis rarely presents as cholestatic hyperbilirubinaemia, and severe bilirubin elevation may lead to bile cast nephropathy. We present a case of a young woman with newly diagnosed Graves' disease with thyrotoxicosis who developed severe hyperbilirubinaemia and bile cast nephropathy. Serial plasma exchange and temporary haemodialysis led to full renal recovery. After treatment of her thyrotoxicosis with antithyroid medication and radioactive iodine ablation, her bilirubin normalised.

Hospitalized patients' and family members' preferences for real-time, transparent access to their hospital records.

OBJECTIVES: To better understand patient satisfaction and perceived engagement with traditional hospital-based communication and to elicit patient preferences for health information technologies that would lead to improved satisfaction and engagement. STUDY DESIGN: We performed a mixed-methods study involving qualitative interviews followed by a survey of hospitalized patients and their family members at a single large academic medical center. METHODS: We conducted semi-structured interviews with 41 patients and surveyed 267 patients or family members to elicit their perspectives on satisfaction with traditional hospital communication methods, information needed to more fully engage in the patients' medical care, and potential solutions for improved hospital-based communication. RESULTS: Qualitative interviews revealed patients' and family members' dissatisfaction with current hospital-based communication methods. They would prefer more information, in more flexible forms, with real-time digital access and the ability to share within their social and healthcare networks. Quantitative results from the survey supported these premises, with at least the majority of the 267 patients surveyed agreeing across each survey question. Furthermore, participants identified a "communications point person" as the individual who organizes, understands, and communicates about the patient's care, who was often a family member not available at the bedside during daily rounds. Potential solutions included improved transparency about hospital processes, creating systems that allow patients and family to help coordinate and double-check their own health-related communications, and delivering hospital-based communications through digital media. CONCLUSIONS: These study findings provide empiric evidence to hospital decision-makers regarding patient and family preferences for 21st-century hospital-based communication systems.

Diabetes mellitus: musculoskeletal manifestations and perioperative considerations for the orthopaedic surgeon.

Diabetes mellitus is a disease of uncontrolled hyperglycemia. Despite a more sophisticated understanding of the pathophysiology of diabetes mellitus and despite pharmacologic advancements that enable better glycemic control, the prevalence of this disease and its devastating sequelae continue to rise. The adverse effects of diabetes on the nervous, vascular, and immune systems render the musculoskeletal system vulnerable to considerable damage. Foot involvement has traditionally been thought of as the most severe and frequently encountered orthopaedic consequence. However, the upper extremity, spine, and muscles are also commonly affected. Orthopaedic surgeons are more involved than ever in the care of patients with diabetes mellitus, and they play a vital role in the multidisciplinary approach used to treat these patients. As a result, surgeons must have a comprehensive understanding of the musculoskeletal manifestations and perioperative considerations of diabetes in order to most effectively care for patients with diabetes mellitus.

Postoperative hyperglycemia and surgical site infection in general surgery patients.

HYPOTHESIS: Postoperative hyperglycemia is an independent risk factor for postoperative surgical site infection (SSI). DESIGN: Retrospective medical record review. SETTING: Academic tertiary referral center. PATIENTS: A total of 2090 general and vascular surgery patients in an institutional quality improvement database between November 1, 2006, and April 30, 2009. MAIN OUTCOME MEASURE: Postoperative SSI. RESULTS: Postoperative glucose levels were available for 1561 patients (74.7.0%), of which 803 (51.4%) were obtained within 12 hours of surgery. The significant univariate predictors of SSI in general surgery patients were increasing age, emergency status, American Society of Anesthesiologists physical status classes P3 to P5, operative time, more than 2 U of red blood cells transfused, preoperative glucose level higher than 180 mg/dL (to convert to millimoles per liter, multiply by 0.0555), diabetes mellitus, and postoperative hyperglycemia. On multivariate adjustment, increasing age, emergency status, American Society of Anesthesiologists classes P3 to P5, operative time, and diabetes remained significant predictors of SSI for general surgery patients. After adjustment for postoperative glucose level, all these variables ceased to be significant predictors of SSI; only incremental postoperative glucose level remained significant. Subanalysis revealed that a serum glucose level higher than 140 mg/dL was the only significant predictor of SSI (odds ratio, 3.2; 95% confidence interval [CI], 1.4-7.2) for colorectal surgery patients. Vascular surgery patients were 1.8 times (95% CI, 1.3-2.5 times) more likely to develop SSI than were general surgery patients. Operative time and diabetes mellitus were the only significant univariate predictors of SSI among vascular surgery patients, and postoperative hyperglycemia was not associated with SSI. CONCLUSIONS: Postoperative hyperglycemia may be the most important risk factor for SSI. Aggressive early postoperative glycemic control should reduce the incidence of SSI.

Hypoglycemia prediction and detection using optimal estimation.

Patients with diabetes play with a double-edged sword when it comes to deciding glucose and A1c target levels. On the one side, tight control has been shown to be crucial in avoiding long-term complications; on the other, tighter control leads to an increased risk of iatrogenic hypoglycemia, which is compounded when hypoglycemia unawareness sets in. Development of continuous glucose monitoring systems has led to the possibility of being able not only to detect hypoglycemic episodes, but to make predictions based on trends that would allow the patient to take preemptive action to entirely avoid the condition. Using an optimal estimation theory approach to hypoglycemia prediction, we demonstrate the effect of measurement sampling frequency, threshold level, and prediction horizon on the sensitivity and specificity of the predictions. We discuss how optimal estimators can be tuned to trade-off the false alarm rate with the rate of missed predicted hypoglycemic episodes. We also suggest the use of different alarm levels as a function of current and future estimates of glucose and the hypoglycemic threshold and prediction horizon.
