Effect of postoperative complications on health and employment following liver transplantation.

The influence of postoperative complications on employment and health status following orthotopic liver transplantation (OLT) remains elusive. Postoperative complications were scored prospectively using a standardized medical outcome classification in each patient transplanted at Duke University from October 1992 to January 1995. Functional status was evaluated by using the Karnofsky score. Between 12 and 18 months following transplantation, patients were asked to complete mailed questionnaires to assess employment and health status (SF-36). The response rate was 86% (42 of 49 eligible patients). The mean patient age was 48 yr. Sixteen of 42 patients (38%) exhibited minimal or no postoperative complications, and 62% exhibited moderate to severe postoperative complications. Age, gender, education, UNOS status for severity of disease, insurance status, and Karnofsky score did not correlate with postoperative complications. Postoperative complications did not predict employment post-transplantation. Paradoxically, patients with minimal or no postoperative complications perceived that their health status was significantly impaired post-transplantation, as evidenced by a median score of 0 in the role-physical subscale of the SF-36, in contrast to those patients with moderate or severe postoperative complications who exhibited a median score of 25 (p < 0.01). Similarly, patients with minimal or no postoperative complications had significantly lower scores on the mental health subscale than those with moderate or severe complications, with median score of 60 vs. 78 (p < 0.03). The physical functioning subscale was not affected by postoperative complications. Thirteen of 42 (31%) respondents returned to full employment post-transplantation. Health perceptions differed with respect to employment status post-transplantation. Patients unemployed post-transplantation exhibited a median score of 55 in the physical functioning subscale, a value much lower than the median score of 80 in the patients who were employed post-transplantation (p < 0.02). No differences in the role physical or mental health subscales were noted with respect to employment status post-transplantation. Employment status was unaffected by Karnofsky status, indicating that functional status does not predict employment. In conclusion, patients exhibited very poor health perceptions post-transplantation, irrespective of postoperative complications. Prospective evaluation of patients undergoing liver transplantation revealed that medical complications did not affect employment post-transplantation.

Effect of interferon-alpha treatment of chronic hepatitis C on health-related quality of life.

Studies of interferon-alpha (IFN-alpha) therapy for chronic hepatitis C have focused on viral clearance; however, few have evaluated patient's health-related quality of life during therapy. This study evaluates health-related quality of life and the prevalence of anxiety and depression in patients with chronic hepatitis C before, during, and following IFN-alpha therapy. Patients undergoing IFN-alpha therapy for chronic hepatitis C were asked to complete health status measures as well as anxiety and depression inventories before, during, and following IFN-alpha therapy. These measures were compared to the results of healthy adults in the general US population. Thirty-eight of forty-eight eligible patients (79%) with chronic hepatitis C completed the questionnaires. Respondents demonstrated a significant increase in depression during the sixth month of interferon therapy in comparison to pretreatment results. Anxiety scores improved significantly after one month of IFN-alpha in comparison to pretreatment results. Scores on the health status measures did not vary with IFN-alpha therapy. Patient responses were analyzed with respect to biochemical response (normalized transaminases) to IFN-alpha. IFN-alpha responders, who were aware of their transaminase results, exhibited lower scores on anxiety subscales during and after therapy (P = 0.02-0.04). Scores on the health status subscale, role emotional, improved in IFN-alpha responders compared to nonresponders during the sixth month of therapy (P = 0.02). Response to IFN-alpha therapy was not associated with any other differences on subscale analysis. Patients with chronic hepatitis C exhibited health perceptions similar to the general US population, and these were unchanged during IFN-alpha therapy. However, the incidence of depression significantly increased during the sixth month of IFN-alpha therapy. IFN-alpha responders exhibited fewer emotional problems as well as a lower incidence of anxiety during and following therapy.

Quantitative assessment of procedural competence. A prospective study of training in endoscopic retrograde cholangiopancreatography.

BACKGROUND: Endoscopic retrograde cholangiopancreatography (ERCP) is a technically demanding procedure that can cause substantial complications. Competence in performing ERCP and the learning curve for achieving competence are poorly understood. OBJECTIVE: To evaluate the number of supervised ERCPs that physicians must do to achieve procedural competence. Competence was defined as a 0.8 probability of successfully completing specific technical components of ERCP and an overall grading of competence as judged by the attending physician. DESIGN: Prospective study. SETTING: University training program for gastroenterologists. PARTICIPANTS: 17 gastroenterology fellows at various stages of training. MEASURES: Experienced therapeutic endoscopists prospectively graded gastroenterology fellows during 1796 consecutive ERCPs. Fellows were graded on their overall level of competence for the procedure and on specific technical components of ERCP. RESULTS: Grading data were available for 1450 ERCPs (81%). The number of ERCPs done before adequate skill was achieved was 160 for cholangiography, 140 for pancreatography, 160 for deep cannulation of the pancreatic duct, 120 for stone extraction, and 60 for stent insertion. Fellows achieved overall competence after completing 180 to 200 ERCPs. The predicted probability of overall competence was 0.8 after 137 ERCPs and 0.9 after 185 ERCPs. CONCLUSIONS: At least 180 ERCPs were required before these gastroenterology fellows could be considered competent in ERCP. This number is much greater than that previously recommended, and these findings have substantial implications for training guidelines and issues of competence and certification in ERCP. The methods used to define and evaluate competence in ERCP could also be used to assess competence in other medical procedures.

Patient-controlled analgesia for conscious sedation during endoscopic retrograde cholangiopancreatography: a randomized controlled trial.

BACKGROUND: Adequate comfort is essential to patients undergoing invasive procedures. This study was designed to evaluate whether patient-controlled analgesia could improve sedation for ERCP. METHODS: Patients were randomized to receive standard sedation (n = 31) or patient-controlled analgesia (n = 31). The patients were blinded to the randomization. After the procedure the patient, physician, and nurse each rated their satisfaction with sedation using a verbal rating scale. RESULTS: There was no significant difference between the patient's mean satisfaction score for the conventional and patient-controlled analgesia groups (9.3 and 9.6, respectively, p = 0.5). The physicians rated sedation higher in the conventional group compared with the patient-controlled analgesia group (8.6 and 8.2, respectively, p = 0.02). Physicians and nurses' scores correlated (r = 0.53, p = 0.0001), but there was no correlation between scores reported by either physicians or nurses and the patients' scores (r = 0.2 and r = 0.05, respectively). Oxygen saturation less than 90% occurred for more than 1 minute in three patients who received standard sedation but in none who used patient-controlled analgesia. CONCLUSION: This trial demonstrates that patient-controlled analgesia during ERCP is as effective as standard sedation with respect to patient satisfaction. Physicians and nurses, however, are not good proxies for assessing patient satisfaction.

Effect of orthotopic liver transplantation on employment and health status.

Employment, functional status, health status, and prevalence of anxiety and depression were assessed in patients who had undergone orthotopic liver transplantation at Duke University from 1984 to 1993 to identify social and economic factors that might influence return to work after liver transplantation. Patients were asked to complete mailed questionnaires. A transplant nurse coordinator assigned patients a Karnofsky score, unaware of the questionnaire responses. The response rate was 71% (52 of 72 patients). The median age of the post-liver transplantation patients was 49 years. Median years of education were 13. Sixty-five percent of patients were male. Sixty percent of patients were employed posttransplantation. Employed and unemployed posttransplantation patients showed no significant difference in age, education, gender, marital status, race, family coping skills, or cause of liver disease. Return to work after transplantation did not correlate with socioeconomic status or spouse's employment. Posttransplantation return to work was highly correlated with pretransplant employment (P < .0005). The prevalence of anxiety and depression, assessed by the Hospital Anxiety and Depression Scale (HAD), was 9% and was no different in the employed or unemployed patients. Health status, as measured by Karnofsky score, was excellent; all patients received Karnofsky scores > or = 80%. Health perceptions were compared in employed versus unemployed posttransplantation patients with the SF-36, a 36-item short form survey developed by the investigators of the Medical Outcome Study. This revealed significantly different values in the subscale, physical functioning, with a mean score of 70.6 in the employed and a mean score of 48.4 in the unemployed posttransplantation patients (P = .004) and role-physical with a mean score of 61.8 in the employed and a mean score of 27.6 in the unemployed posttransplantation patients (P = .005). Eighty percent of patients not returning to work cited "problems with their health" as their major obstacle to employment. Although objective health status was good to excellent in all patients after transplantation, patients perceived that their health status was poor, with the lowest scores observed in unemployed posttransplantation patients.
