I try to care for all my young patients the way I would want my own children to be cared for, and I do my best to get to know each patient and understand what matters to them, beyond the orthopedic problem at hand. How well the patient, his or her family, and I get to know each other and work together to make decisions in the office is just as important as the technical details of an operation.

My number-one motivation is the happiness and satisfaction that I see in my patients when I have helped them with a problem and they are back to living life and doing what makes them happy.

I lived in Honduras and managed a primary care clinic for two years before I started medical school. It was a formative time in my life, and I found that I truly enjoy working at the front lines and taking care of patients on a daily basis. Recently, I was able to return to Guatemala on a surgical mission with Operation Rainbow and my colleagues Dr. Rinsky and Dr. Gamble.

Admission Through the Emergency Department Is an Independent Risk Factor for Lower Satisfaction With Physician Performance Among Orthopaedic Surgery Patients: A Multicenter Study JOURNAL OF THE AMERICAN ACADEMY OF ORTHOPAEDIC SURGEONS Vorhies, J. S., Weaver, M. J., Bishop, J. A. 2016; 24 (10): 735-742


Patient experience data are increasingly used to guide performance improvement and to determine physician and hospital reimbursement. We studied the relationship between emergency department (ED) admission and patient satisfaction with physicians' performance, and identified other associated predictors.We evaluated 6,524 inpatient Press Ganey patient experience surveys from two academic level I trauma centers over 5 years. We stratified patients by ED admission or other admission and compared the proportions of patients in each group who were satisfied with physician performance. We used logistic regression to control for demographic differences and characteristics of hospitalizations.Among patients admitted through the ED, 85.18% were satisfied, compared with 89.44% of patients admitted through other pathways (P < 0.001). Admission through the ED predicted decreased satisfaction, with an odds ratio of 0.67 (P = 0.032) after controls were applied through logistic regression.Admission through the ED is an independent risk factor for lower satisfaction with physician performance. Understanding the determinants of patient satisfaction will help improve physician-patient interactions and guide quality improvement and value-based reimbursement initiatives.This retrospective survey-based analysis of satisfaction does not fall clearly under any of the Journal's established categories of level of evidence. The most closely aligned choice would be Level III Prognostic.

Legal restrictions and complications of abortion: Insights from data on complication rates in the United States JOURNAL OF PUBLIC HEALTH POLICY Rolnick, J. A., Vorhies, J. S. 2012; 33 (3): 348-362


Although US federal law requires all American states to permit abortion within their borders, states retain authority to impose restrictions.We used hospital discharge data to study the rates of major abortion complications in 23 states from 2001 to 2008 and their relationship to two laws: (i) restrictions on Medicaid the state insurance programs for the poor funding, and (ii) mandatory delays before abortion. Of 131 000 000 discharges in the data set, 10 980 involved an abortion complication. The national rate for complications was 1.90 per 1000 abortions (95 per cent CI: 1.572.23). Eleven states required mandatory delays and 12 restricted funding for Medicaid participants. After controlling for socioeconomic characteristics and the pregnancy complication rate, legal restrictions were associated with lower complication rates: mandatory delays (OR 0.79(0.650.95)) and restricted Medicaid funding (OR 0.74 (0.610.90)). This result may reflect the fact that states without restrictions perform a higher percentage of second-trimester abortions. This study is the first to assess the association between legal restrictions on abortion and complication rates.

Decreased Length of Stay After TKA Is Not Associated With Increased Readmission Rates in a National Medicare Sample CLINICAL ORTHOPAEDICS AND RELATED RESEARCH Vorhies, J. S., Wang, Y., Herndon, J. H., Maloney, W. J., Huddleston, J. I. 2012; 470 (1): 166-171


There is a trend toward decreasing length of hospital stay (LOS) after TKA although it is unclear whether this trend is detrimental to the overall postoperative course. Such information is important for future decisions related to cost containment.We determined whether decreases in LOS after TKA are associated with increases in readmission rates.We retrospectively reviewed the rates and reasons for readmission and LOS for 4057 Medicare TKA patients from 2002 to 2007. We abstracted data from the Medicare Patient Safety Monitoring System. Hierarchical generalized linear modeling was used to assess the odds of changing readmission rates and LOS over time, controlling for changes in patient demographic and clinical variables.The overall readmission rate in the 30days after discharge was 228/4057 (5.6%). The 10 most common reasons for readmission were congestive heart failure (20.4%), chronic ischemic heart disease (13.9%), cardiac dysrhythmias (12.5%), pneumonia (10.8%), osteoarthrosis (9.4%), general symptoms (7.4%), acute myocardial infarction (7.0%), care involving other specified rehabilitation procedure (6.3%), diabetes mellitus (6.3%), and disorders of fluid, electrolyte, and acid-base balance (5.9%); the top 10 causes did not include venous thromboembolism syndromes. We found no difference in the readmission rate between the periods 2002-2004 (5.5%) and 2005-2007 (5.8%) but a reduction in LOS between the periods 2002-2004 (4.12.0days) and 2005-2007 (3.81.7days).The most common causes for readmission were cardiac-related. A reduction in LOS was not associated with an increase in the readmission rate in this sample. Optimization of cardiac status before discharge and routine primary care physician followup may lead to lower readmission rates.

Readmission and Length of Stay After Total Hip Arthroplasty in a National Medicare Sample JOURNAL OF ARTHROPLASTY Vorhies, J. S., Wang, Y., Herndon, J., Maloney, W., Huddleston, J. I. 2011; 26 (6): 119-123


Evaluation of hospital readmissions after total hip arthroplasty may help improve patient safety and cost reduction. This study investigates the rates and reasons for readmission as well as length of hospital stay (LOS) for 1802 total hip arthroplasty patients from 2002 to 2007. Data were abstracted from the Medicare Patient Safety Monitoring System. The overall 30-day rate of readmission was 6.8%. There was no difference in readmission rate from 2002 to 2004 (7.1%) to 2005 to 2007 (6.3%) (odds ratio, 0.90; 95% confidence interval, 0.63-1.30; P = .58). The overall mean LOS was 4.2 2.2 days. There was a significant reduction in LOS from 2002 to 2004 (4.4 2.5 days) to 2005 to 2007 (3.8 1.7 days) (odds ratio, 1.28; 95% confidence interval, 1.25-1.31; P < .0001). The most common causes for readmission were cardiac related. A reduction in LOS was not associated with an increase in the rate of readmission in this sample. Efforts to optimize cardiac status before discharge may lead to lower rates of readmission in the future.
