Abstract
AIMS To evaluate the healthcare resource use (HRU) and cost of lost productivity due to migraine among Italians with ≥4 monthly migraine days (MMDs), with a focus on those with ≥2 prior preventive treatment failures (TFs). MATERIALS AND METHODS Data from Italian participants from the My Migraine Voice survey were used to assess migraine-related HRU and migraine's impact on work productivity and daily activities using the Work Productivity and Activity Impairment questionnaire. The mean, annualized cost of lost productivity was estimated using the Human Capital Approach and extrapolated to employed Italian population with ≥4 MMDs to calculate the overall migraine-related indirect cost burden in Italy. RESULTS Data of 420 participants, enrolled between September 2017 and February 2018, were analyzed (mean age: 38.5 years, 81.2% women, 37.8% with ≥2 TF). During a 6-month period, 57.6% of participants visited general practitioners (mean visits: 4.5), 31.9% neurologists (mean visits: 2.6), and 26.4% headache specialists (mean visits: 2.8). Overall, 32.0% of participants had ≥1 emergency room visit (mean visits: 2.8) and 15.0% had ≥1 hospitalization (mean visits: 2.9) because of migraine in the past 12 months. Participants who were employed (N = 215) reported 15.5% absenteeism, 45.3% presenteeism, 53.8% overall work impairment, and 52.6% activity impairment. The mean annualized indirect cost was estimated to be €14,368. The annual indirect cost burden was estimated to be €7.6 billion for the employed Italian population with ≥4 MMDs. The impact of migraine was particularly high among the ≥2 TF subgroups on all parameters. The indirect cost was estimated to be €15,881 (€5,007 attributed to absenteeism). CONCLUSION Migraine-related HRU and indirect costs are high among individuals with ≥4 MMDs (particularly those with ≥2 TF). There is a need for more effective treatments and better management of migraines to reduce the functional and economic burden among this difficult-to-treat population.

Abstract
BACKGROUND The effect of certolizumab pegol on employment status and work productivity has not been previously assessed. AIM To assess the impact of treatment with certolizumab pegol, the only PEGylated, Fab' TNF antagonist, on work productivity in patients with active Crohn's disease (CD) from the PRECiSE 2 study. METHODS Patients (n = 668) with active disease [CD activity index (CDAI) score of 220-450] were treated with open-label subcutaneous certolizumab pegol 400 mg (week 0, 2, 4). Responders (n = 425) (> or = 100-point decrease in CDAI from baseline) were randomized to receive certolizumab pegol 400 mg or placebo every 4 weeks until week 24, with final evaluation at week 26. Patients completed the Work Productivity and Activity Impairment for CD questionnaire (WPAI:CD) and the Inflammatory Bowel Disease Questionnaire (IBDQ) at weeks 0, 6, 16 and 26 and at the withdrawal visit. RESULTS Work productivity improved following induction with certolizumab pegol. Between week 6 and 26, certolizumab pegol-treated patients experienced significant improvement in work productivity compared with placebo recipients (11% and 10% overall improvement in work and activity impairment, respectively). During the maintenance phase, impairments in productivity and activities due to CD were significantly less in the certolizumab pegol group than in the placebo group. CONCLUSION Induction and maintenance therapy with certolizumab pegol significantly improved the work productivity of patients with active CD compared with those in the placebo group.

Abstract
OBJECTIVE To determine the validity, reliability and responsiveness of the Work Productivity and Activity Impairment questionnaire in AS (WPAI:SpA). METHODS Baseline and Week-24 data from a randomized, double-blind study of adalimumab in patients with AS were used. Discriminative validity of WPAI:SpA absenteeism, presenteeism, overall work productivity loss and activity impairment scores was assessed relative to patient-reported outcomes: Bath AS Disease Activity Index (BASDAI), AS Quality of Life Questionnaire (ASQOL), Short-Form 36 Health Survey (SF-36), Physical and Mental Component Summaries (PCS and MCS, respectively) and Health Utilities Index Mark 3 (HUI-3). Responsiveness of the WPAI:SpA instrument was assessed for patients meeting the minimum clinically important differences (MCIDs) for ASQOL and BASDAI (i.e. quality of life and clinical responders, respectively) and quantified with standardized response mean (SRM) calculations. RESULTS Of 315 patients, 205 were employed at baseline. Patients with more severe AS (BASDAI > median) showed significantly greater impairment in work and daily activities than patients with lesser disease severity (P < 0.001). This trend was consistent for ASQOL, SF-36 PCS, SF-36 MCS and HUI-3. There were significant differences in WPAI:SpA scores for patients achieving BASDAI clinical response and ASQOL quality of life response vs non-responders. For responders, SRMs were large for work presenteeism, overall work impairment and activity impairment (-0.86 to -1.29 for BASDAI; -0.89 to -1.18 for ASQOL) and small for absenteeism (-0.25 for BASDAI; -0.31 for ASQOL). CONCLUSIONS The WPAI:SpA is a valid, reliable and responsive tool for assessing work productivity for patients with AS.

Abstract
BACKGROUND Crohn's disease (CD) is a chronic inflammatory bowel disease usually diagnosed in early adult life and characterized by unpredictable flares and debilitating symptoms such as diarrhea, abdominal pain, and fever, which can interfere with a patient's ability to work and perform daily activities. OBJECTIVE The aim of this study was to assess the validity, reliability, and responsiveness of the Work Productivity and Activity Impairment questionnaire in CD (WPAI:CD). METHODS The WPAI:CD was tested in CD patients enrolled in a 26-week randomized clinical trial of cer-tolizumab pegol versus placebo. Discriminative validity of WPAI:CD absenteeism, presenteeism(reduced on-the-job effectiveness), overall work productivity loss (absenteeism + presenteeism), and activity impairment scores was assessed relative to 5 measures of disease severity and health status: CD Activity Index (CDAI), Short Form-36 physical component summary (PCS) and mental health component summary (MCS) scores, Inflammatory Bowel Disease Questionnaire (IBDQ), and the 5-dimensional EuroQoL health-related quality-of-life visual analog scale (EQ-VAS). Responsiveness was assessed by comparing changes in WPAI:CD scores from baseline to week 26 for patients in remission (CDAI <150 points) versus no remission. Standardized Response Means (SRMs) were calculated to evaluate the magnitude of the changes. RESULTS A total of 662 patients (mean [range] age, 37.4 [18-77] years; male, 288 [43.5%]; white, 629 [95.0%]) were enrolled in the study. Patients with CD of the worst severity (CDAI > median) showed significantly higher impairment in work (+10.5%) and activities (+10.4%) versus patients with "best health" (no problems) (both, P < or = 0.001). Patients with "worst" IBDQ, PCS, MCS, and EQ-VAS scores also showed significantly higher impairments in work (IBDQ, VAS -24.2%; PCS, -24.1%; MCS, -15.9%; EQ-VAS, -16.5%) and activities (IBDQ, -23.3%; PCS, -21.8%; MCS, -16.5%; EQ-VAS, -17.2%) versus "best" scores (all, P < 0.05). There were significant differences between WPAI:CD impairment scores for patients in remission versus patients failing to achieve remission (P < 0.05). SRMs were small (ie, <0.5) in the nonre-mission group, and moderate to large (ie, >0.5) for patients in remission. CONCLUSIONS The discriminative validity, reliability, and responsiveness of the WPAI:CD were demonstrated. The WPAI:CD may be useful for evaluating drug impact on CD.

Abstract
In mild Alzheimer's disease (AD), loss of relationship with the patient is a significant consequence for the partner (relative) and may be amenable to improvement with effective intervention. To evaluate relationship dynamics, the authors developed and tested content and discriminative validity of the self-administered Partner-Patient Questionnaire for Shared Activities among 100 partners of patients with mild to moderate Alzheimer's disease. Principal component analysis confirmed that interference in 17 activities derived from the literature and partner-specified activities comprised a relationship factor; internal consistency was very high. Time spent caregiving, caregiver esteem, lack of family support, and impact on partner health and activities were significant predictors of the Partner-Patient Questionnaire for Shared Activities, but the patient's cognitive and mood states were not. The Partner-Patient Questionnaire for Shared Activities warrants additional psychometric testing as a measure of Alzheimer's disease outcome.

Abstract
BACKGROUND Gastro-oesophageal reflux disease has wide-ranging effects on patients' lives. AIM To review systematically the effects of gastro-oesophageal reflux disease on work productivity. METHODS Studies of gastro-oesophageal reflux disease and work productivity were identified in a systematic literature search and their results were valued in US dollars using the human capital method. Work productivity loss was defined as absence from work (absenteeism) plus reduced effectiveness while working (presenteeism). RESULTS Eight eligible studies were included. Reported work productivity loss among individuals with gastro-oesophageal reflux disease ranged from 6% to 42% and was primarily because of presenteeism (6-40%) rather than absenteeism (<1% to 7%). Reported losses were greatest in patients experiencing sleep disturbance because of gastro-oesophageal reflux disease, and lowest in individuals from the general population taking appropriate prescription medication. Work productivity impairment correlated with symptom severity and responded to acid-suppressive therapy. Assuming a 40-h working week and average wages in the US, the weekly mean productivity loss per employee with gastro-oesophageal reflux disease can be estimated between 2.4 (62 dollars) and 16.6 h (430 dollars), depending on the population studied. CONCLUSIONS Gastro-oesophageal reflux disease has a substantial impact on employee productivity, primarily by impairing productivity while working. Further studies are needed to confirm that this impact can be decreased by acid-suppressive therapy.

Abstract
INTRODUCTION There are no measures of health-related absenteeism and presenteeism validated for use in the large and increasing US Spanish-speaking population. Before using a Spanish translation of an available English-language questionnaire, the linguistic validity of the Spanish version must be established to ensure its conceptual equivalence to the original and its cultural appropriateness. OBJECTIVE The objective of this study was to evaluate the linguistic validity of the US Spanish version of the Work Productivity and Activity Impairment questionnaire, General Health Version (WPAI:GH). METHODS A US Spanish translation of the US English WPAI:GH was created through a reiterative process of creating harmonized forward and back translations by independent translators. Spanish-speaking and English-speaking subjects residing in the US self-administered the WPAI:GH in their primary language and were subsequently debriefed by a bilingual (Spanish-English) interviewer. RESULTS US Spanish subjects (N = 31) and English subjects (N = 35), stratified equally by educational level, with and without a high school degree participated in the study. The WPAI-GH item comprehension rate was 98.6% for Spanish and 99.6% for English. Response revision rates during debriefing were 1.6% for Spanish and 0.5% for English. Responses to hypothetical scenarios indicated that both language versions adequately differentiate sick time taken for health and non-health reasons and between absenteeism and presenteeism. CONCLUSION Linguistic validity of the US Spanish translation of the WPAI:GH was established among a diverse US Spanish-speaking population, including those with minimal education.

Abstract
OBJECTIVES To assess the comparability, reliability, and subject acceptability of electronic data capture (EDC) versions of Irritable Bowel Syndrome-Quality of Life (IBS-QOL), EuroQoL (EQ-5D) and Work Productivity and Activity Impairment (WPAI:IBS) instruments. METHODS Comparability of EDC and paper questionnaires was evaluated in 72 subjects with IBS who completed a baseline EDC or paper questionnaire, a crossover questionnaire 24 hours later, and a retest of the crossover version at 1 week. The EDC version was presented on a hand-held device. Comparability was assessed using paired t-test statistics, intraclass correlation coefficients (ICC) and tests for internal consistency (Cronbach's alpha). RESULTS No significant differences were found between scores obtained by paper questionnaire and EDC at the baseline and crossover assessments. ICCs between baseline and crossover assessments ranged from 0.83 to 0.96 for the IBS-QOL scores, 0.82 to 0.96 for the WPAI:IBS scores, and 0.77 to 0.82 for the EQ-5D. Internal consistency was comparable for the two data collection methods for the IBS-QOL overall score (0.96) and subscales and the EQ-5D Index (0.70 vs. 0.74). Retest statistics (ICC) were generally comparable between the EDC and paper versions for all scores. Ease of use was comparable for the two modes of administration, but more patients preferred EDC (47.2%) than the paper questionnaire (23.6%). CONCLUSIONS EDC versions of the IBS-QOL, EQ-5D, and WPAI:IBS are comparable to paper questionnaires in internal consistency and test-retest reliability, and have greater patient acceptability.

Abstract
BACKGROUND Tegaserod is a promotility agent with proven efficacy and safety in patients with irritable bowel syndrome with constipation. AIM To assess tegaserod's effect on work productivity and daily activity. METHODS Women, 18-65 years old and meeting Rome II criteria for irritable bowel syndrome with constipation, were randomized to a double-blind, placebo-controlled, multicentre study of tegaserod 6 mg b.d. or placebo. Productivity loss and daily activity impairment because of irritable bowel syndrome were measured with the Work Productivity and Activity Impairment questionnaire for irritable bowel syndrome, modified to exclude diarrhoea as a symptom. Assessments were made at baseline, weeks 2 and 4. RESULTS A total of 2660 women were randomized and, of these, 1675 [tegaserod (n = 1363), placebo (n = 312)] were employed and completed Work Productivity and Activity Impairment for irritable bowel syndrome questionnaires. Compared with placebo, tegaserod significantly reduced work and daily activity impairment at weeks 2 and 4. Tegaserod reduced absenteeism by 2.6% (P = 0.004), presenteeism by 5.4% (P < 0.0001), overall work productivity loss by 6.3% (P < 0.0001), and activity impairment by 5.8% (P < 0.0001) at week 4 (vs. baseline). Assuming a 40-h workweek, tegaserod reduced work productivity loss by 2.5 h/week. CONCLUSIONS Tegaserod significantly reduced work productivity loss and daily activity impairment at 2 weeks, and this benefit was maintained at 4 weeks.

Abstract
BACKGROUND Irritable bowel syndrome is a common chronic functional gastrointestinal disorder characterized by recurrent abdominal pain and discomfort associated with alterations in bowel habit. Irritable bowel syndrome affects patients' quality of life and increases productivity loss. AIM To assess validity and accuracy of the Work Productivity and Activity Impairment questionnaire in irritable bowel syndrome as a tool for quantifying the effects of irritable bowel syndrome on productivity and daily activities. METHODS Validity and accuracy were evaluated in 135 irritable bowel syndrome patients relative to three measures of irritable bowel syndrome disease severity; a debriefing questionnaire; retrospective diary; Work Limitations Questionnaire, and an activity impairment measure (Dimensions of Daily Activities). RESULTS Symptom severity scores, diary scores, Work Limitations Questionnaire and Dimensions of Daily Activities were significant predictors of work productivity and activity impairment questionnaire in irritable bowel syndrome measures of work time missed, and work and activity productivity loss (P = 0.04 to < 0.0001). Impairment due to irritable bowel syndrome was estimated to be 2.9-4.3% for work time missed and 22-32% for impairment at work, the equivalent of 9.7 -14 h lost productivity per week. Activity impairment was 24-41%. CONCLUSIONS Discriminative validity of the Work Productivity and Activity Impairment questionnaire in irritable bowel syndrome was established, making it the only validated tool for measuring the relative differences between disease severity groups and quantifying work productivity loss and activity impairment in irritable bowel syndrome patients.

Abstract
Various methods of percutaneous fixation of tibial plateau fractures are available. The optimal method of fixation is dictated by soft tissue injury, fracture characteristics, and functional demands of the patient. Unicondylar fractures are amenable to percutaneous stabilization with screws or plates although some fractures are best approached with open techniques. Hybrid and ring external fixators are most appropriate for patients with bicondylar injuries who have severe soft tissue trauma. Use of intramedullary nails to align ipsilateral shaft fractures adjacent to percutaneously fixed plateau injuries remains controversial but may be indicated for some patients with bicondylar lesions and combined plateau and shaft fractures.

Abstract
OBJECTIVE To determine the incidence of superior gluteal artery injury following fracture of the acetabulum and to determine whether the combination of a superior gluteal artery injury and the use of an extended iliofemoral approach to the acetabulum creates abductor muscle necrosis. DESIGN Prospective protocol, consecutive cases. SETTING A consecutive series from the referral practice of the senior author plus seven cases from the practices of two other authors. PATIENTS Two hundred twenty-seven patients with fractures of the acetabulum were treated operatively between November 1992 and January 1995. Forty-one were treated with the use of the extended iliofemoral approach. Preoperative angiograms were not performed for any of the patients. All fractures involved the posterior column, and all but two fractures had displacement of the greater sciatic notch. The average displacement of the notch was 2.5 centimeters (range 6 to 60 millimeters). INTERVENTION All patients were treated with open reduction and internal fixation via the extended iliofemoral approach. Intraoperative Doppler examination of the superior gluteal artery was performed before and after reduction and fixation of the posterior column. MAIN OUTCOME MEASURE Wound complications, abductor manual muscle testing, hip range of motion. RESULTS Pulsatile flow was confirmed in forty of forty-one patients. All patients were followed for a minimum of six months with an average follow-up of 1.4 years. At most recent follow-up, no patients had evidence of complete loss of abductor function. Sixty-three percent of patients had achieved Grade 4 of 5 motor strength, and 25 percent of them had achieved normal motor strength. CONCLUSIONS No instances of superior gluteal artery laceration and only one instance of superior gluteal artery thrombosis were encountered in these forty-one patients despite significant fracture displacement involving the sciatic notch. The incidence of superior gluteal artery injury was significantly less than would be expected from previous studies. Massive abductor necrosis resulting from superior gluteal artery injury combined with an extended approach has been described primarily in animal and cadaver studies. Although arteriograms are useful in the control of hemodynamic instability, we cannot support the recommendation of preoperative angiographic study of all patients undergoing acetabular fracture surgery via an extended approach. In one case, an extended iliofemoral approach was tolerated in a patient with absent superior gluteal artery flow.

Abstract
Unstable fractures of the pelvic ring are an increasingly frequent outcome of motor vehicle trauma. Neurologic injury after such injuries can be a cause of significant morbidity. The available literature on neurologic injuries was reviewed and compared with a clinical review of 90 unstable pelvic injuries treated during a 3-year period. Eighty-three patients were available for followup examination. Neurologic injuries were seen in 21 % of the patients. Thirty-seven percent of patients had sensory deficits alone whereas the remaining 63% had motor and sensory findings. All patients showed some evidence of neurologic recovery at an average or 24-months followup. At least 1 grade of muscle function improvement was consistently seen and 53% of patients had complete neurologic recovery. Improvement in function was seen as many as 24 months postinjury, but L5 function was least likely to progress to full recovery. The incidence of neurologic injuries and their distribution was similar to that reported in the literature, whereas the prognosis for neurologic recovery was significantly better. This may be related to techniques of early anatomic reduction and stabilization of unstable pelvic ring injuries.

Abstract
Reversed-phase liquid chromatographic fractions of extracts of 2 preparations of eosinophilia-myalgia syndrome (EMS)-associated L-tryptophan were analyzed by proton nuclear magnetic resonance spectrometry, mass spectrometry, microbial-growth inhibition, and amino acid residue analyses. Fraction components demonstrated properties of an antibiotic peptide resembling bacitracin. Many peptide antibiotics like bacitracin are secondary metabolites of Bacillus species, genus of the tryptophan producer organism for the implicated manufacturer. In order to determine whether a correlation exists between individual EMS cases and the concentration of peptides or bacitracin consumed, reliable methods must be developed for quantification of the total of isoforms.

Abstract
The construct validity of a quantitative work productivity and activity impairment (WPAI) measure of health outcomes was tested for use in clinical trials, along with its reproducibility when administered by 2 different methods. 106 employed individuals affected by a health problem were randomised to receive either 2 self-administered questionnaires (self administration) or one self-administered questionnaire followed by a telephone interview (interviewer administration). Construct validity of the WPAI measures of time missed from work, impairment of work and regular activities due to overall health and symptoms, were assessed relative to measures of general health perceptions, role (physical), role (emotional), pain, symptom severity and global measures of work and interference with regular activity. Multivariate linear regression models were used to explain the variance in work productivity and regular activity by validation measures. Data generated by interviewer-administration of the WPAI had higher construct validity and fewer omissions than that obtained by self-administration of the instrument. All measures of work productivity and activity impairment were positively correlated with measures which had proven construct validity. These validation measures explained 54 to 64% of variance (p less than 0.0001) in productivity and activity impairment variables of the WPAI. Overall work productivity (health and symptom) was significantly related to general health perceptions and the global measures of interference with regular activity. The self-administered questionnaire had adequate reproducibility but less construct validity than interviewer administration. Both administration methods of the WPAI warrant further evaluation as a measure of morbidity.

Abstract
A pilot study was conducted to compare symptoms elicited with an open-ended question versus a checklist and to measure the responsiveness of quality-of-life measures to symptom severity. The pilot study was part of a multicentre, randomised, double-blind, placebo-controlled study of clentiazem, a calcium channel blocker, in the treatment of essential hypertension. Symptom and quality-of-life data were obtained from 88 patients at baseline and after 10 weeks of therapy by a trained telephone interviewer. Comparison of the symptom checklist and open-ended question method suggests that both methods are necessary to capture severe symptomatology. The 24-item checklist failed to elicit approximately 50% of the severe symptoms reported on the open question list. On the other hand, only 18% of the most severe symptoms subsequently reported on the checklist were first reported by the open question method. The responsiveness of quality-of-life measures to symptom severity was tested using a 20% change in symptom severity obtained from the checklist as the minimal clinically significant difference. Using Guyatt's formula, a minimum sample size of approximately 428 (alpha = 0.05, beta = 0.10) patients per treatment group is required to detect differences in measures of general health perception, anxiety, depression and limitations in social activities. A larger sample is required to show differences in leisure activities. Differences in limitations of the capability to perform house or yard work might be demonstrable with as few as 17 patients per group. This pilot study demonstrated that the severity of symptoms associated with hypertension, and the side effects of its treatment with drugs, are adequately captured by a symptom checklist preceded by an open-ended method of questioning. Responsiveness testing estimated the sample size required to show a statistically significant difference, assuming a 20% change in symptom severity.

Abstract
The cost of an average outpatient visit to a physician at a Veterans Administration hospital in 1976 was estimated from hospital records to have been $80.35 ($104.46 in 1979 dollars). When productivity was used to measure relative cost, cost per visit ranged from a low of $32.66 (1979: $42.46) for hypertension clinic to a high of $243.48 (1979; $316.52) for hematology clinic. The average patient was seen 12.6 times annually at a cost of $1012 (1979: $1315). The major cost category for a physician visit was salaries, with nonphysician salaries costing twice as much as physician salaries. The cost of medical equipment was minimal. The findings suggest that the outpatient bookkeeping system was inadequate for cost accounting, the cost per visit was expensive, there were an excessive number of visits, and problems in the institutional delivery system of ambulatory care lowered productivity of physicians.

Abstract
The place of longitudinal myotomy in the treatment of diverticular disease of the sigmoid colon is discussed, with passing reference to the drawbacks of transverse myotomy. The prime indication for longitudinal myotomy is in the longstanding uncomplicated case of troublesome diverticular disease that has not responded to correct medical treatment, which should include high-residue diet and bran. Such cases are usually over 50 years of age, when a functional and reversible obstruction has become organic and irreversible. They comprise 75% of a series of 104 cases described. A secondary indication is in cases of diverticular disease which have been complicated by perforation, abscess formation, acute intestinal obstruction or fistulae. Such cases comprise 25% of the present series. They may settle after drainage and/or defunctioning colostomy. Myotomy can be carried out later, with or without limited resection, provided that all signs of pus or peritonitis have disappeared. The technique of the operation is described and the results are analysed.

Abstract
This article is a critical review of empiric studies, in the medical care literature of the past two decades, that investigated associations between characteristics of physicians and medical care institutions and some measure of the quality of medical care given by them. The intention is to identify those characteristics of physicians and medical care institutions which can be considered the best indicators of the quality of performance to be expected, given the present state of knowledge. The analysis discusses 18 such characteristics but derives a list of 14 which appear to be the best choice of indicators on which further research might focus. It would be possible to design a survey instrument based on these characteristics, which, if upheld by empiric testing, could serve as a crude assessment tool for third parties needing to make quality comparisons between medical care institutions.
