Quality of life measures in health care. I: Applications and issues in assessment

A short generic patient experience questionnaire: howRwe development and validation

Background

Patient experience is a key quality outcome for modern health services, but most existing survey methods are long and setting-specific. We identified the need for a short generic questionnaire for tracking patient experience.

Methods

We describe the development and validation of the howRwe questionnaire. This has two items relating to clinical care (treat you kindly; listen and explain) and two items relating to the organisation of care (see you promptly; well organised) as perceived by patients. Each item has four responses (excellent, good, fair and poor). The questionnaire was trialled in 828 patients in an orthopaedic pre-operative assessment clinic (PAC).

Results

The howRwe questionnaire is shorter (29 words) and more readable (Flesch-Kincaid grade score 2.2) than other questionnaires with broadly similar objectives. Psychometric properties in this sample are good with Cronbach’s α=0.82. Following a change to the appointments system in the clinic, howRwe showed improvement in promptness and organisation, but not in kindness and communication, showing that it can distinguish between the clinical and organisational aspects of patient experience.

Conclusions

howRwe meets the criteria for a short generic patient experience questionnaire that is suitable for frequent use. In the validation study of PAC patients, it showed good psychometric properties and concurrent, construct and discriminant validity.

Comparison of two assessment instruments of quality of life in older adults

OBJECTIVE

To investigate if there is convergent validity between the dimensions of the World Health Organization Quality of Life Questionnaire-Brief Version (WHOQOL-Bref) and the Oral Health Impact Profile-14 (OHIP-14) questionnaire.

METHODS

In this cross-sectional study, a random sample of 872 elderly Southern-Brazilians was evaluated. Questionnaires assessing socio-demographic data and quality of life in general (WHOQOL-Bref) and oral health-related quality of life (OHIP-14) were used. Analysis of the WHOQOL-Bref and OHIP-14 questionnaires used descriptive statistics. The dimensions of the WHOQOL-Bref and OHIP-14 questionnaires were correlated by affinity. The convergence between WHOQOL-Bref and OHIP-14 dimensions was analyzed by Spearman's correlation coefficients.

RESULTS

The social relations dimension of the WHOQOL-Bref presented the greatest mean (18.24 ± 2.30). The physical pain dimension of the OHIP-14 presented a median of 1.0 (0.0 - 3.0). All correlations between the WHOQOL-Bref and OHIP-14 dimensions were significant, negative and associated with a low magnitude. The correlation between WHOQOL-physical and OHIP-functional limitation, OHIP-physical pain, OHIP-physical disability and OHIP-handicap were - 0.164, - 0.262, - 0.196 and - 0.125 respectively. WHOQOL-psychological was associated with OHIP-psychological discomfort and OHIP-psychological disability, and WHOQOL-social showed an association with OHIP-social disability.

CONCLUSIONS

All correlations analyzed had a positive association of low magnitude. Despite the fact that the WHOQOL-Bref and OHIP-14 instruments have related dimensions, they measure physical, psychological and social relations differently.

Quality of life and self-esteem in patients with paraplegia and pressure ulcers: a controlled cross-sectional study

OBJECTIVE

To evaluate health-related quality of life (HRQoL) and self-esteem in patients with traumatic spinal cord injury (SCI) and pressure ulcers.

METHOD

This study was a controlled cross-sectional study. HRQoL was assessed using the generic Medical Outcomes Study 36-Item Short Form Health Survey (SF-36) questionnaire and the Rosenberg Self-Esteem/UNIFESP-EPM Scale. A total of 120 patients with traumatic SCI were included in the sample, of which 60 had pressure ulcers and were assigned to the study group, and 60 had no pressure ulcers and were assigned to the control group. Statistical analysis was performed using the chi-square test, Fisher's exact test, and Student's t-test.

RESULTS

Of the 60 patients in the study group, 83.3% were men and the mean age was 38.17 years (SD = 9.08 years). When compared with controls, patients in the study group reported significantly lower scores (worse health status) on all SF-36 subscales (p less than or equal to 0.0013) except for general health (p=0.109). The RSE/UNIFESP-EMP scale total score indicated that patients with pressure ulcers had significantly lower self-esteem than controls (p<0.001).

CONCLUSION

Pressure ulcers had an adverse impact on the HRQoL and self-esteem of patients with SCI.

Predictors of changes in physical, psychosocial, sexual quality of life, and comfort with food after obesity surgery: a 12-month follow-up study

PURPOSE

Although obesity surgery provides significant postoperative improvement in quality of life (QoL), it is still unclear which factors might predict improvement in QoL after surgery. We aimed to determine which factors might predict changes in physical, psychosocial, sexual QoL, and comfort with food 12 months after surgery, by putting to the test a QoL model based on Wilson and Cleary's model.

METHODS

We included 126 obese patients (48.4% had gastric banding, 34.1% had sleeve gastrectomy, and 17.5% had gastric bypass). At baseline, we assessed QoL (Quality of Life, Obesity and Dietetics rating scale), BMI, depression (Beck Depression Inventory), and binge eating (Bulimic Investigatory Test, Edinburgh). At 12 months, we assessed QoL and BMI. To determine the predictors for changes in each QoL dimension after surgery, we used linear mixed models adjusted for preoperative age, BMI, time, type of surgery, preoperative binge eating severity, and preoperative depression severity.

RESULTS

After 12 months, we found significant improvement in physical, psychosocial, sexual QoL, but not in comfort with food. Increased weight loss was associated with better improvement in physical and psychosocial QoL. Higher preoperative depression severity predicted poorer improvement in physical, psychosocial, and sexual QoL. Higher preoperative binge eating severity predicted poorer improvement in psychosocial, sexual QoL, and comfort with food.

CONCLUSIONS

In addition to weight loss, preoperative levels of binge eating and depression should be considered as important predictors for QoL changes after bariatric surgery. Screening and treatment for preoperative depression and binge eating might improve QoL after bariatric surgery.

Functional assessment measures in rheumatologic disorders

Rheumatologic disorders cause functional impairment and significantly affect health-related quality of life. Functional assessment and health-related quality of life scales are increasingly being used as outcome measures to assess the influence of the diseases and health outcome in clinical studies of patients with rheumatologic diseases. In this article, we review the functional assessment and health-related quality of life measures which have been commonly used as outcome measures in rheumatologic disorders. These measures are Short form-36 (SF-36), SF-12, Nottingham Health Profile, Sickness Impact Profile, EuroQol, SF-6D, Health Utilities Index mark 2 and 3, Stanford Health Assessment Questionnaire, Rheumatoid Arthritis Quality of Life Questionnaire, Arthritis Impact Measurement Scales, McMaster Toronto Arthritis Patient Preference Disability Questionnaire, Western Ontario and McMaster Universities Osteoarthritis Index, Lequesne Index, Knee Disability and Osteoarthritis Outcome Score, Knee Disability and Osteoarthritis Outcome Score-Physical Function Short-form, Hip Disability and Osteoarthritis Outcome Score, Hip Disability and Osteoarthritis Outcome Score-Physical Function SF, Fibromyalgia Impact Questionnaire, Psoriatic Arthritis Quality of Life Scale, Gout Assessment Questionnaires, Dougados Functional Index, Bath Ankylosing Spondylitis Functional Index, and Ankylosing Spondylitis Quality of Life Scale.

Translation, adaptation and validation of a Portuguese version of the Moorehead-Ardelt Quality of Life Questionnaire II

The prevalence of obesity has increased worldwide. An assessment of the impact of obesity on health-related quality of life (HRQoL) requires specific instruments. The Moorehead-Ardelt Quality of Life Questionnaire II (MA-II) is a widely used instrument to assess HRQoL in morbidly obese patients. The objective of this study was to translate and validate a Portuguese version of the MA-II.The study included forward and backward translations of the original MA-II. The reliability of the Portuguese MA-II was estimated using the internal consistency and test-retest methods. For validation purposes, the Spearman's rank correlation coefficient was used to evaluate the correlation between the Portuguese MA-II and the Portuguese versions of two other questionnaires, the 36-item Short Form Health Survey (SF-36) and the Impact of Weight on Quality of Life-Lite (IWQOL-Lite).One hundred and fifty morbidly obese patients were randomly assigned to test the reliability and validity of the Portuguese MA-II. Good internal consistency was demonstrated by a Cronbach's alpha coefficient of 0.80, and a very good agreement in terms of test-retest reliability was recorded, with an overall intraclass correlation coefficient (ICC) of 0.88. The total sums of MA-II scores and each item of MA-II were significantly correlated with all domains of SF-36 and IWQOL-Lite. A statistically significant negative correlation was found between the MA-II total score and BMI. Moreover, age, gender and surgical status were independent predictors of MA-II total score.A reliable and valid Portuguese version of the MA-II was produced, thus enabling the routine use of MA-II in the morbidly obese Portuguese population.

Patient-reported outcomes following a physiotherapy rehabilitation programme for atraumatic posterior shoulder subluxation

BACKGROUND

There is a paucity of research that describes the patient-reported benefits of physiotherapy rehabilitation for atraumatic posterior instability despite non-operative treatment being considered the initial treatment of choice. This retrospective case series review describes the patient-reported outcomes following a physiotherapy rehabilitation programme for atraumatic posterior shoulder instability.

METHODS

Nineteen consecutive patients with a clinical diagnosis of atraumatic posterior shoulder subluxation completed our physiotherapy programme. All patients completed Oxford Instability Shoulder scores (OISS) and Western Ontario Shoulder Instability Index (WOSI) scores before and after physiotherapy intervention.

RESULTS

Patients reported a statistically significant clinical improvement in the main outcome measures following physiotherapy intervention. The OISS showed a mean improvement of 18.6 points, whereas the WOSI score showed a mean improvement of 37.2%. Following physiotherapy rehabilitation, all patients reported that their shoulder did not prevent them from performing their work/studies or their chosen hobbies/sports.

CONCLUSIONS

Our results support the view that specialized physiotherapy rehabilitation is a valuable treatment option for atraumatic posterior shoulder instability and reveal significant clinically important improvements in patient-reported outcomes.

Quality of life instruments used in mental health research: properties and utilization

Quality of life (QoL) assessment is increasingly used in mental health. Multiple instruments exist, but the conditions for choosing one instrument over another for purposes of a specific study are not clear. We performed a systematic review to identify the QoL instruments used in mental health. The instruments were systematically described regarding their intrinsic properties (e.g., generic v. disease-specific) and their characteristics of utilization in studies (e.g., study objectives). Using cluster analyses, we investigated the existence of similar instruments with respect to each of these sets of characteristics and studied potential links between instruments' intrinsic properties and their characteristics of utilization. We included 149 studies in which 56 distinct instruments were used. Similarities were found among instruments in terms of their intrinsic properties as well as their characteristics of utilization, leading to the construction of four clusters of instruments in each case. However, no relevant links were identified between instruments' intrinsic properties and their characteristics of utilization, suggesting that the choice of QoL instruments did not depend on their properties. A consensus about common QoL instruments must be reached to facilitate the choice of instruments, the comparison of results and thus to have an impact on clinical and policy decision-making.

Is the health status of female victims poorer than males in the post-disaster reconstruction in China: a comparative study of data on male victims in the first survey and double tracking survey data

BACKGROUND

The health of females is more at risk during disasters. Studies that focus on the comparison of males and time span are few. This article focuses on the health-related quality of life (HRQOL) of female victims in the post-disaster reconstruction in China. We aim to reduce gender health inequalities by comparing and analyzing gender differences in HRQOL. Moreover, we analyze the trends in HRQOL of female victims by using tracking data, and then provide reasonable suggestions to enhance the HRQOL.

METHODS

This article explores the HRQOL of women victims in the post-disaster reconstruction from two perspectives: a comparison between males and a time span of six-month intervals. We conducted the first survey, and the double tracking survey in 2013. This study uses data from half a year later sample surveys collected from five counties (Wenchuan, Qingchuan, Mianzhu, Lushan, and Dujiangyan) in Sichuan in 2013 (N = 2000).

RESULTS

(1) By calculating the Cronbach's alpha coefficients of the SF-12 scale, we found that that reliability of the scale and the internal consistency are good. (2) Using SF-12 instead of SF-36 to measure the HRQOL of survivors is feasible. (3) The ANOVA and non-parametric testing methods show that significant differences exist between the eight dimensions of HRQOL in different genders after the earthquake. (4) After six months, the HRQOL of female victims in the post-disaster reconstruction has also undergone a significant change. (5) Compared with male victims, we should give more attention to female victims' HRQOL issues in the post-disaster reconstruction in Sichuan. (6) The performances of victims in the post-disaster reconstruction in PCS and MCS affect each other.

CONCLUSION

We found that in terms of gender, the male and female victims' HRQOL after the disaster largely varied: (1) In general, significant difference exists between male and female victims in terms of HRQOL. The HRQOL of female victims is poorer than that of male victims. (2) The PCS and MCS of victims affect each other. However, for female victims, the degree of influence of MCS on PCS is larger than that in males. (3) The MCS of female victims is more vulnerable than that of male victims. In terms of time span, the following information was obtained: (1) after six months of rest, victims' HRQOL significantly improved. (2) At this stage, relative to the MCS, the PCS of females should be given more attention.

Three-year outcomes of cultured limbal epithelial allografts in aniridia and Stevens-Johnson syndrome evaluated using the Clinical Outcome Assessment in Surgical Trials assessment tool

Limbal stem cell deficiency (LSCD) is an eye disorder in which the stem cells responsible for forming the surface skin of the cornea are destroyed by disease. This results in pain, loss of vision, and a cosmetically unpleasant appearance. Many new treatments, including stem cell therapies, are emerging for the treatment of this condition, but assessment of these new technologies is severely hampered by the lack of biomarkers for this disease or validated tools for assessing its severity. The aims of this study were to design and test the reliability of a tool for grading LSCD, to define a set of core outcome measures for use in evaluating treatments for this condition, and to demonstrate their utility. This was achieved by using our defined outcome set (which included the Clinical Outcome Assessment in Surgical Trials of Limbal stem cell deficiency [COASTL] tool) to evaluate the 3-year outcomes for allogeneic ex vivo cultivated limbal epithelial transplantation (allo-CLET) in patients who had bilateral total LSCD secondary to aniridia or Stevens-Johnson syndrome. The results demonstrate that our new grading tool for LSCD, the COASTL tool, is reliable and repeatable, and that improvements in the biomarkers used in this tool correlate positively with improvements in visual acuity. The COASTL tool showed that following allo-CLET there was a decrease in LSCD severity and an increase in visual acuity up to 12 months post-treatment, but thereafter LSCD severity and visual acuity progressively deteriorated.

Self and parent perspectives on health-related quality of life of adolescents born very preterm

OBJECTIVES

To test whether health-related quality of life (HRQL) based on societal standards differs between very low birth weight/very preterm (VLBW/VP) and full-term (FT) adolescents using self and parent proxy reports. Also, to examine whether self and parent reported HRQL is explained by indicators of objective functioning in childhood.

STUDY DESIGN

This prospective cohort study followed 260 VLBW/VP adolescents, 12 VLBW/VP adolescents with disability, and 282 FT adolescents. Objective functioning was assessed at 8.5 years; HRQL was assessed at 13 years with the Health Utilities Index Mark 3 (HUI3).

RESULTS

Adolescents reported more functional impairment than their parents especially in the psychological aspects of health. The mean difference in HUI3 multi-attribute utility scores between FT and VLBW/VP adolescents was small (parents: 0.91 [95% CI, 0.90, 0.92] vs 0.88 [95% CI, 0.86, 0.90]; adolescents: 0.87 [95% CI, 0.85, 0.89] vs 0.84 [95% CI, 0.82, 0.86]), but high for VLBW/VP adolescents with disabilities (0.18, 95% CI, -0.04, 0.40). Objective function did not predict HRQL in FT adolescents but contributed to prediction of HRQL in VLBW/VP adolescents without disabilities. Different indicators of objective functioning were important for adolescent vs parent reports. More variation in HUI3 scores was explained by objective function in VLBW/VP parent reports compared with adolescent reports (25% vs 18%).

CONCLUSIONS

VLBW/VP adolescents reported poorer HRQL than their FT peers in early adolescence. Improvement in HRQL as VLBW/VP children grow up is, at least partly, explained by exclusion of the most disabled in self reports by VLBW/VP adolescents and the use of different reference points by adolescents compared with parents.

Younger patients report greater improvement in self-reported function after knee joint replacement

STUDY DESIGN

Retrospective chart review.

OBJECTIVES

To evaluate and compare the relationship between patients' age and the change in Oxford Knee Score from preoperative to postoperative assessments, and to investigate whether there is a relationship between preoperative Oxford Knee Score results and the indication for total knee replacement surgery, and if age affects this relationship.

BACKGROUND

An increasing number of younger patients receive knee joint replacements, yet it is unknown how this cohort functions after surgery. This warrants investigation into the potential age-related differences in joint function following surgery. The Oxford Knee Score has been validated as a clinical tool but has yet to be accepted in the decision-making process regarding the need for, or appropriateness of, total knee replacement.

METHODS

In a retrospective chart review, 240 patients completed the Oxford Knee Score questionnaire to evaluate chronic pain and/or dysfunction associated with the knee.

RESULTS

The largest improvement with joint replacement was observed to occur in the youngest patient group (50-59 years old). Moreover, the Oxford Knee Score was shown to be the strongest predictor (odds ratio = 0.61) for the indicated intervention when compared to other predictors. The youngest patient group reported a significantly (P<.03) higher Oxford Knee Score result when indicated for surgery, compared to the oldest patient group (80-89 years old).

CONCLUSION

The results provide insight into how age influences self-perceived joint function before and after joint replacement surgery, and into the clinical decision to provide the surgical option to younger patients. Moreover, the observed relationship between the Oxford Knee Score and the indicated treatment supports the use of the questionnaire as a preoperative tool in considering treatment options for patients with knee osteoarthritis.

LEVEL OF EVIDENCE

Prognosis, level 2b.

Outcome instruments for the shoulder

Outcome surveys may play a vital role in the future of orthopaedics. Institutions may increasingly look toward determining the effectiveness of treatment options, but different validation studies often yield different results. There is a clear need for consistency when reporting patient-reported outcome scores. Knowledge of the available outcome scores and their strengths and weaknesses will allow orthopaedic surgeons to practice evidence-based medicine, offer their patients the most appropriate treatments, and successfully navigate the increasingly complex reimbursement system. Orthopaedic surgeons will need to show conclusively that their procedures improved patient outcomes and were cost-effective. We conducted a review of upper extremity outcome systems commonly used in the shoulder and their scoring and validation.

The effectiveness of hydrotherapy in the management of rheumatoid arthritis: a systematic review

BACKGROUND

Hydrotherapy is frequently indicated for the rehabilitation of patients with rheumatoid arthritis (RA); nevertheless, there has been inadequate appraisal of its effectiveness. The potential benefits of hydrotherapy for patients with RA are to improve and/or maintain functional ability and quality of life.

OBJECTIVES

The aim of this systematic review was to evaluate the effectiveness of hydrotherapy in the management of patients with RA.

METHOD

AMED, CINAHL, EMBASE, MEDLINE, PubMed, Science Direct and Web of Science were searched between 1988 and May 2011. Keywords used were rheumatoid arthritis, hydrotherapy, aquatic physiotherapy, aqua therapy and water therapy. Searches were supplemented with hand searches of references of selected articles. Randomized controlled trials were assessed for their methodological quality using the Physiotherapy Evidence Database (PEDro) scale. This scale ranks the methodological quality of a study scoring 7 out of 10 as 'high quality', 5-6 as 'moderate quality' and less than 4 as 'poor quality'.

RESULTS

Initially, 197 studies were identified. Six studies met the inclusion criteria for further analysis. The average methodological quality for all studies was 6.8 using the PEDro scale. Most of the studies reported favourable outcomes for a hydrotherapy intervention compared with no treatment or other interventions for patients with RA. Improvement was particularly noted in reducing pain, joint tenderness, mood and tension symptoms, and increasing grip strength and patient satisfaction with hydrotherapy treatment in the short term.

CONCLUSIONS

There is some evidence to suggest that hydrotherapy has a positive role in reducing pain and improving the health status of patients with RA compared with no or other interventions in the short term. However, the long-term benefit is unknown. Further studies are needed.

Oral health-related quality of life among parents and teachers of disabled schoolchildren in Kuwait

OBJECTIVE

The objective of this study was to assess the oral health-related quality of life between the parents and the teachers of disabled schoolchildren in Kuwait.

SUBJECTS AND METHODS

The three category response version of the General Oral Health Assessment Index (GOHAI) (12 questions, always, sometimes, never) was used in the questionnaires in Kuwait. Three hundred and eight (308) parents and 112 teachers were enrolled in this study.

RESULTS

The mean age of the parents was 45 ± 9.9 years and of the teachers 38 ± 8.4 years. The mean GOHAI was 27.2 ± 3.5 among the parents and 27.8 ± 3.3 among the teachers (p = 0.091). GOHAI was higher in the older age groups (p = 0.002) and among the parents with a university education (p < 0.001). GOHAI was also higher with increasing toothbrushing frequency among the parents (p = 0.047) and the teachers (p = 0.003). Altogether, 203 (66%) of the parents and 85 (76%) of the teachers were always able to swallow comfortably; 123 (40%) of the parents and 41 (37%) of the teachers were able to eat without discomfort. Overall, 132 (43%) of the parents and 41 (37%) of the teachers were always pleased and happy with the looks of their teeth and gums, or dentures. The Cronbach's alpha (0.83) indicated a high degree of internal consistency between different GOHAI items.

CONCLUSION

There seemed to be no difference in the impact of oral health on the quality of life between the parents and the teachers of disabled schoolchildren. Oral health had a relatively weak impact on the quality of life of these adults.

Health-related quality of life after total joint arthroplasty: a scoping review

A scoping review was completed to summarize the change in health status after THA and TKA. Although a recent study has performed a systematic review of functional recovery after THA,(61) we reviewed a broad topic of HRQL changes after total joint arthroplasty. This scoping review was not restricted by study design; however, the majority of studies were prospective single group, observational studies so that change over time could be reported. A variety of HRQL measures were used, including disease-specific, generic, and utility measures. We reported on 33 studies that met our inclusion criteria. Most studies’ primary outcomes were disease-specific measures. Not surprisingly, MCIDs were reported with recovery both short term and long term. These clinically relevant changes were accompanied with large effect sizes for pain and function using disease-specific measures such as the WOMAC. In general, smaller changes were reported with joint stiffness; however, this may also be related to inherent measurement properties of the WOMAC in that it uses two questions to evaluate stiffness. Overall, large effect sizes, in excess of 1.0, were seen not only short term but also long term, that is, more than a year after surgery. The changes may also be reflected in the low rate of complications reported with total joint arthroplasty.(62) The generic health measures showed a smaller magnitude of change, which is to be expected given the construct of these measures evaluate overall health and includes the effect of other health conditions. That being said, the largest changes were seen in those domains that were primary to total joint arthroplasty, pain and physical function. A challenge of evaluating change of health status after total joint arthroplasty is that each measure has individual strengths and limitations. This review introduced the measures and the MCIDs when available to evaluate clinical change. The derived MCIDs should be considered carefully because these values are dependent on a number of features such as the study setting, methodology used to derive the values, baseline scores, and severity of the disease.(63) Change over time was also presented by the effect sizes. The effect size provided another perspective to measuring recovery after total joint arthroplasty in which comparison across measures can be made. Regardless of the type of outcome measure, large effect sizes are seen with total joint arthroplasty both over short-term and long-term outcomes. Because a number of HRQL measures are used to evaluate the outcomes after total joint arthroplasties, comparisons can be challenging. This review summarized published findings to help place the magnitude of change seen with total joint arthroplasty in perspective. Changes seen with HRQL are one aspect of evaluating outcomes from a patient perspective; however, recovery is a complex concept(64) that needs many clinical and research-oriented measures to evaluate the full spectrum of recovery.

Quality of life of the mentally ill. Reliability of the Swedish version of the Lancashire Quality of life profile

There has been a growing interest in the quality of life (QoL) of the mentally ill, subsequently a number of instruments to measure QoL have been developed. One of the measures of QoL which has received considerable attention is the Lancashire QoL Profile (LQOLP). The present study investigated test-retest reliability and internal consistency in the Swedish translation of the LQOLP using a cross-sectional sample of 29 inpatients. The results showed that test-retest reliability of subjective life satisfaction in the nine life domains covered by the LQOLP was satisfactory in seven of the domains, and acceptable in two (social relations and religion). Test-retest reliability for total subjective satisfaction score, global well-being, and an interviewer rated QoL were all on a satisfactory level (r > 0.80). The internal consistency and homogeneity of the total subjective QoL scale and the nine life domain subscales was satisfactory except for the social relations scale, where it was somewhat low.

Patient-reported outcome data generated in a clinical intervention in community mental health care--psychometric properties

BACKGROUND

DIALOG is an intervention to structure the communication between patient and key worker, which has been shown to improve patient outcomes in community mental health care. As part of the intervention, patients provide ratings of their subjective quality of life (SQOL) on eight Likert type items and their treatment satisfaction on three such items. This study explored the psychometric qualities of the outcome data generated in the DIALOG intervention to explore whether they may be used for evaluating treatment outcomes.

METHOD

Data were taken from 271 patients who received the DIALOG intervention. All patients were diagnosed with schizophrenia or a related disorder and treated in community mental health care. For SQOL and treatment satisfaction as assessed in the DIALOG intervention, we established the internal consistency (Cronbach's alpha), the convergent validity of SQOL items (correlation with Manchester Short Assessment of Quality of Life [MANSA]) and treatment satisfaction items (correlation with Client Satisfaction Questionnaire [CSQ]), the concurrent validity (correlations with Positive and Negative Syndrome Scale [PANSS]) and the sensitivity to change (t-test comparing ratings of the first and last intervention). We also explored the factorial structure of the eight SQOL items.

RESULTS

The internal consistency of the eight SQOL items was .71 and of the three treatment satisfaction items .57. SQOL scores were correlated with the MANSA (r = .95) and PANSS scores (general psychopathology: r = -.37, positive symptoms: r = -.27, negative symptoms: r = -.27). Treatment satisfaction scores were correlated with the CSQ (r = 0.36) and the PANSS (r = -.29, -.20, -.20). SQOL and treatment satisfaction score improved significantly over time. SQOL items loaded on two meaningful factors, one capturing health and personal safety and one reflecting other life domains.

CONCLUSIONS

The psychometric qualities of the SQOL scores generated in DIALOG are strong. The properties of the three treatment satisfaction items may be seen as acceptable. Although DIALOG has been designed as a therapeutic intervention, it can generate outcome data on SQOL and treatment satisfaction with acceptable psychometric qualities.

Health-related quality of life: expanding a conceptual framework to include older adults who receive long-term services and supports

For older adults receiving long-term services and supports (LTSS), health-related quality of life (HRQoL) has emerged as a critical construct to examine because of its focus on components of well-being, which are affected by progressive changes in health status, health care, and social support. HRQoL is a health-focused quality of life (QOL) concept that encompasses aspects of QOL that affect health such as function, physical, and emotional health. Examining existing theoretical constructs and indicators of HRQoL among LTSS recipients led us to posit a revised conceptual framework for studying HRQoL among LTSS recipients. We adapted the Wilson and Cleary HRQoL model by expanding function to specifically include cognition, adding behavior and LTSS environmental characteristics in order to create a more robust HRQoL conceptual framework for older adults receiving LTSS. This refined conceptual model allows for the measurement of a mix of structural, process, and outcome measures. Continued development of a multidimensional conceptual framework with specific HRQoL measures that account for the unique characteristics of older adults receiving LTSS will contribute significantly to LTSS research, policy, and planning efforts.

Improvement of quality of life following 6 months of methadone maintenance therapy in Malaysia

BACKGROUND

Methadone Maintenance Therapy (MMT) is one of the popular choices for drug substitution therapy and is fairly new in Malaysia. Aside from its role in harm reduction against HIV infection, MMT programme may potentially enhances clients' quality of life. This study aims to identify the impact of MMT programme on clients' quality of life after 6 months in treatment and to explore factors that may be associated with changes in their quality of life.

METHODS

In this retrospective report review, 122 subjects from 2 government MMT clinics were selected from the district of Tampin, Negeri Sembilan, Malaysia. The raw score from the WHO Quality of Life questionnaire (WHOQOL-BREF), at baseline and 6 months after therapy were collected and converted to 0-100 scale form to give quality of life scores for four domains; physical, psychological, social relationships and environment. Other variables of interest were socio-demography, age when joining MMT programme, age and duration of illicit drug use, HIV and Hepatitis C status, and the Opiate Treatment Index (OTI) score on drug use, sexual and social aspect at the baseline. Statistical analysis used the SPSS version 16.

RESULTS

There was significant improvement in all four domains of quality of life, after 6 months of MMT. The largest improvement was for psychological domain (mean score difference 15.54 ± 20.81). Multivariable linear regression analysis showed that, for the physical domain, there was no significant predictor. For both the psychological and social domains, having tertiary education is a significant predictor for improvement in both aspects of quality of life. Negative HIV status is associated with improvement for the environment domain.

CONCLUSIONS

There was a significant short term improvement in the quality of life of MMT clients who stayed in the programme for at least 6 months in the district of Tampin, Negeri Sembilan, Malaysia.

Development of a disease-specific quality-of-life questionnaire for anterior and central skull base pathology--the skull base inventory

OBJECTIVES/HYPOTHESIS

Anterior and central skull base lesions and their surgical treatment (endoscopic or open approaches) can affect quality of life. A disease-specific instrument is needed to compare quality of life for different surgical approaches.

STUDY DESIGN

Items were generated using a composite strategy consisting of chart review, systematic review of skull base instruments, expert interviews, and qualitative analysis of patient focus groups. A cross-sectional survey study was performed to reduce items based on an item impact score.

METHODS

Charts of 138 patients who underwent skull base surgery were reviewed to identify physical items and domains. Five experts were interviewed for item and domain identification. Thirty-four patients were recruited into eight focus groups based on their surgical approach (open or endoscopic) and tumor location (anterior or central). Items were generated using a composite approach and then reduced into a final questionnaire using item impact scores.

RESULTS

Chart review identified 47 physical items. Systematic review revealed nine relevant instruments with 217 relevant items. Experts identified 11 domains with 69 additional items. Qualitative analysis of focus groups generated 49 items. A total of 382 items were identified and reduced to 77 items after eliminating overlapping and irrelevant items. Further item reduction using item impact scores yielded 41 items.

CONCLUSIONS

The Skull Base Inventory is a disease-specific quality-of-life instrument. Psychometric properties have yet to be tested. It may serve to compare quality of life for endoscopic or open procedures.

Development and validation of a multidimensional quality of life questionnaire for congenital aural atresia

CONCLUSION

The psychometric characteristics of the Congenital Aural Atresia Questionnaire (CAAQ) are proposed to be reliable and sensitive to determine clinical changes in a patient's quality of life (QOL) and the questionnaire has potential for clinical application.

OBJECTIVE

The aim of this study was to develop a quantifiable, self-assessed, and health-related QOL questionnaire for patients with congenital aural atresia and to explore its reliability and validity.

METHODS

An initial QOL questionnaire for patients with congenital aural atresia was constructed according to widely used available QOL questionnaires. A total of 140 patients with congenital aural atresia were recruited into this study. After pretest and item sifting, the QOL questionnaire was constructed, and its reliability and validity were evaluated.

RESULTS

An 18-item QOL questionnaire for patients with congenital aural atresia was constructed, which included 3 principal domains: symptoms and impact (physical, 8 items), mental status (psychological, 6 items), and social interaction (4 items). The retest reliability was 0.878; split-half reliability coefficient and Cronbach's alpha coefficient were 0.927 and 0.899, respectively. The factor analysis results indicated satisfactory construct validity.

Effect of telehealth on use of secondary care and mortality: findings from the Whole System Demonstrator cluster randomised trial

OBJECTIVE

To assess the effect of home based telehealth interventions on the use of secondary healthcare and mortality.

DESIGN

Pragmatic, multisite, cluster randomised trial comparing telehealth with usual care, using data from routine administrative datasets. General practice was the unit of randomisation. We allocated practices using a minimisation algorithm, and did analyses by intention to treat.

SETTING

179 general practices in three areas in England.

PARTICIPANTS

3230 people with diabetes, chronic obstructive pulmonary disease, or heart failure recruited from practices between May 2008 and November 2009.

INTERVENTIONS

Telehealth involved remote exchange of data between patients and healthcare professionals as part of patients' diagnosis and management. Usual care reflected the range of services available in the trial sites, excluding telehealth.

MAIN OUTCOME MEASURE

Proportion of patients admitted to hospital during 12 month trial period.

RESULTS

Patient characteristics were similar at baseline. Compared with controls, the intervention group had a lower admission proportion within 12 month follow-up (odds ratio 0.82, 95% confidence interval 0.70 to 0.97, P = 0.017). Mortality at 12 months was also lower for intervention patients than for controls (4.6% v 8.3%; odds ratio 0.54, 0.39 to 0.75, P < 0.001). These differences in admissions and mortality remained significant after adjustment. The mean number of emergency admissions per head also differed between groups (crude rates, intervention 0.54 v control 0.68); these changes were significant in unadjusted comparisons (incidence rate ratio 0.81, 0.65 to 1.00, P = 0.046) and after adjusting for a predictive risk score, but not after adjusting for baseline characteristics. Length of hospital stay was shorter for intervention patients than for controls (mean bed days per head 4.87 v 5.68; geometric mean difference -0.64 days, -1.14 to -0.10, P = 0.023, which remained significant after adjustment). Observed differences in other forms of hospital use, including notional costs, were not significant in general. Differences in emergency admissions were greatest at the beginning of the trial, during which we observed a particularly large increase for the control group.

CONCLUSIONS

Telehealth is associated with lower mortality and emergency admission rates. The reasons for the short term increases in admissions for the control group are not clear, but the trial recruitment processes could have had an effect.

[Prospective evaluation of an intravaginal electrical stimulation in the treatment of women with pure genuine stress urinary incontinence]

OBJECTIVES

To study the objective and subjective effectiveness of transvaginal electrical stimulation for treatment of female pure genuine stress incontinence.

PATIENTS AND METHODS

This was a multicenter prospective trial including 207 patients with genuine stress incontinence who used the stimulator for 10 weeks. Similar pre-treatment and post-treatment assessments included both validated symptom severity index and health-related quality of life.

RESULTS

Objective evaluation showed a significant improvement in 65.7% of subjects with stress incontinence. All domains of quality of life improved significantly after treatment (P=0.0001) and rate of satisfactory was 84.7%. There were no statistical differences between the two stimulators.

DISCUSSION AND CONCLUSION

Pelvic floor electrical stimulation seems to be effective in treating female genuine stress incontinence and could be considered first-line therapy.

Responsiveness of the Manchester-Oxford Foot Questionnaire (MOXFQ) compared with AOFAS, SF-36 and EQ-5D assessments following foot or ankle surgery

The responsiveness of the Manchester-Oxford Foot Questionnaire (MOXFQ) was compared with foot/ankle-specific and generic outcome measures used to assess all surgery of the foot and ankle. We recruited 671 consecutive adult patients awaiting foot or ankle surgery, of whom 427 (63.6%) were female, with a mean age of 52.8 years (18 to 89). They independently completed the MOXFQ, Short-Form 36 (SF-36) and EuroQol (EQ-5D) questionnaires pre-operatively and at a mean of nine months (3.8 to 14.4) post-operatively. Foot/ankle surgeons assessed American Orthopaedic Foot and Ankle Society (AOFAS) scores corresponding to four foot/ankle regions. A transition item measured perceived changes in foot/ankle problems post-surgery. Of 628 eligible patients proceeding to surgery, 491 (78%) completed questionnaires and 262 (42%) received clinical assessments both pre- and post-operatively. The regions receiving surgery were: multiple/whole foot in eight (1.3%), ankle/hindfoot in 292 (46.5%), mid-foot in 21 (3.3%), hallux in 196 (31.2%), and lesser toes in 111 (17.7%). Foot/ankle-specific MOXFQ, AOFAS and EQ-5D domains produced larger effect sizes (> 0.8) than any SF-36 domains, suggesting superior responsiveness. In analyses that anchored change in scores and effect sizes to patients' responses to a transition item about their foot/ankle problems, the MOXFQ performed well. The SF-36 and EQ-5D performed poorly. Similar analyses, conducted within foot-region based sub-groups of patients, found that the responsiveness of the MOXFQ was good compared with the AOFAS. This evidence supports the MOXFQ's suitability for assessing all foot and ankle surgery.

[Validation of the Brazilian version of the generic six-dimensional short form quality of life questionnaire (SF-6D Brazil)]

OBJECTIVE

This study seeks to present the translation and validation of the SF-6D in the Brazilian context, based on the model and the version developed in the United Kingdom in 2002.

METHODS

An observational and transversal study. The tools for assessing quality of life were applied, namely HAQ, SF-36, EQ-5D and SF-6D (2002 version). Descriptive statistics and correlation coefficients were used for data analysis.

RESULTS

200 patients with rheumatoid arthritis, with a mean age of 49.22 years, 11.16 years of disease and mean HAQ 1.02 were studied. Preferences measured by the SF-6D, the EQ-5D and the techniques of EVA, TTO and SG were found to correlate among themselves, with Pearson coefficients from 0.19 to 0.66 (p <0.01).

CONCLUSION

The SF-6D Brazil questionnaire represents a valid option for assessing preferences on economic analysis conducted in Brazil.

Quality of life among adults with confirmed dengue in Brazil

The main objective of this study was to measure the quality of life (QoL) during a dengue episode. We conducted a facility-based survey in central Brazil in 2005 and recruited 372 laboratory-confirmed dengue patients greater than 12 years of age in hospital and ambulatory settings. We administered the World Health Organization QoL instrument approximately 15 days after the onset of symptoms. We used principal component analysis with varimax rotation to identify domains related to QoL. The median age of interviewees was 36 years. Most (85%) reported their general health status as very good or good before the dengue episode. Although ambulatory patients were mainly classified as having dengue fever, 44.8% of hospitalized patients had dengue hemorrhagic fever or intermediate dengue. Principal component analysis identified five principal components related to cognition, sleep and energy, mobility, self-care, pain, and discomfort, which explained 73% of the variability of the data matrix. Hospitalized patients had significantly lower mean scores for dimensions cognition, self-care, and pain than ambulatory patients. This investigation documented the generally poor QoL during a dengue episode caused by the large number of domains affected and significant differences between health care settings.

Cross-cultural adaptation of the Brazilian-Portuguese version of the chronic urticaria quality-of-life questionnaire - CU-Q2oL

BACKGROUND

Chronic urticaria (CU) is a debilitating skin disorder that affects patients' health related quality of life and the only questionnaire prepared specifically to CU is the Chronic Urticaria Quality of Life Questionnaire (CU-Q(2)oL).

OBJECTIVE

The purpose of this study was to cross-culturally adapt and validate the CU-Q(2)oL Brazilian-Portuguese version.

METHODS

Forward and back translation by three bilingual translators followed by pre-test was used to adapt the questionnaire. The CU-Q(2)oL was self-administered along with the Dermatology Life Quality Index (DLQI) in 112 patients with CU. Disease activity was assessed using the Urticaria Activity Score. Factor analysis was used to identify scales of the Brazilian portuguese CU-Q(2)oL. Internal consistency, convergent validity and known-group validity was determined. Reproducibility was evaluated by interclass correlation coefficient (ICC). Multiple linear regression was used to determine the predicting factors of CU-Q(2)oL results.

RESULTS

Factor analysis revealed a three-dimensional structure: sleep/mental status/eating (I), pruritus/impact on life activities (II) and swelling/limits/look (III), which explained 52.49% of the total variance. All scales showed excellent internal consistency. External construct validity was supported by correlations between the CU-Q(2)oL and DLQI. The tool was found to be able to differentiate between patients with high and low levels of urticaria activity. Test-retest reliability was good to excellent (ICC = 0.69-0.86). Disease severity and urticaria type were the only factors predicting results.

CONCLUSIONS

The CU-Q(2)oL Brazilian portuguese version was easily filled out, well accepted by the patients, demonstrated an acceptable validity and reliability and might be used to evaluate treatment outcomes and in clinical research.

The range of the Oxford Shoulder Score in the asymptomatic population: a marker for post-operative improvement

INTRODUCTION

The Oxford Shoulder Score (OSS) is a validated scoring system used to assess the degree of pain and disability caused by shoulder pathology. To date there is no knowledge of the range of the OSS in the healthy adult population. This study aimed to establish the range in asymptomatic individuals.

METHODS

The OSS of 100 asymptomatic volunteers was compared with the pre-operative OSS of 100 symptomatic individuals who had had elective shoulder surgery performed at the Royal Preston hospital.

RESULTS

The difference in mean scores in the operated group (36.7) and the asymptomatic group (15.3) was statistically significant (p<0.0001). There was, however, a substantial overlap between the scores of the two groups (operated group range: 19-55, asymptomatic group range: 12-47). Factors such as age, sex, body mass index, co-morbidities and smoking did not have a statistically significant impact on the eventual score in the asymptomatic group.

CONCLUSIONS

This study has established the range of OSS in the asymptomatic adult population. Symptom scores can only be used effectively when the range in the asymptomatic population is known. This is so that disease severity can be gauged in the context of the normal population and post-operative improvements can be forecast more accurately.

Patient-reported outcomes for irritable bowel syndrome are associated with patients' severity ratings of gastrointestinal symptoms and psychological factors

BACKGROUND & AIMS

Patient-reported outcomes (PROs) are used to gauge the benefit of treatments for functional gastrointestinal disorders, including irritable bowel syndrome (IBS). Commonly used end points derived from scales of symptom severity differ in their structure, format, and the extent to which they are based on established psychometric fundamentals. We evaluated the overlap between 2 measures of IBS symptom severity, documented their association with different symptoms (pain, bloating, altered defecation), and identified psychological factors that might bias PRO ratings, by affecting how patients interpret IBS symptom severity.

METHODS

Ninety-eight patients diagnosed with IBS, based on Rome III criteria, completed the multicomponent IBS Symptom Severity Scale and the single-item, UCLA Symptom Severity Scale. Data were collected on pain, bloating, and bowel habits, as well as somatization, sensitivity to arousal symptoms (anxiety sensitivity), and a negative thinking style called pain catastrophizing.

RESULTS

The 2 global scales were correlated with one another (r = 0.56); each scale was associated most strongly with variation in abdominal pain. Data were consistent with a model in which pain catastrophizing and somatization influenced 1 or more of patients' judgments of pain, bloating, and/or bowel habits, which then affected the PROs.

CONCLUSIONS

Depending on their structure and format, PROs can have different levels of sensitivity to core IBS symptoms and be influenced by psychological and somatic complaints that are beyond the aim of therapy and labeling claim. PROs that rely on patients' perspectives to index symptom severity can be improved by consideration of psychometric principles that influence self-report.

Psychometric properties of the Chinese quality of life instrument (HK version) in Chinese and Western medicine primary care settings

Background

The Chinese Quality of Life Measure (ChQOL) had only been validated on a small number of selected subjects in Hong Kong and had never been tested in the Western medicine (WM) primary care setting.

Aims and objectives

To test the psychometrics properties of ChQOL(HK version) in both TCM and WM general outpatient clinics.

Methods

Three samples of Chinese adult patients [(1) 569 consulting TCM clinics for episodic illnesses; (2) 524 consulting WM clinics for episodic illnesses; (3) 205 consulting WM clinics for chronic disease follow-up] in Hong Kong were invited to complete the ChQOL(HK version) and the SF-36 Health Survey during their consultations and 2 weeks after consultations. The scaling assumptions, factor structure, convergent construct validity, reliability, responsiveness, and discriminatory power of the ChQOL were evaluated.

Results

Majority of items satisfied the scaling assumptions. A two instead of 3-factor structure was found with physical form and emotion facets loading on one factor. Convergent construct validity was confirmed with moderate correlations with SF-36 scores. Internal consistency and test–retest reliability were satisfactory. The ChQOL(HK version) was able to detect significant improvements 2 weeks after consultations, and it was able to discriminate between groups with different illness severity, age, and sex.

Conclusion

The ChQOL(HK version) was shown to have satisfactory validity, reliability, discriminatory power, and responsiveness in both TCM and Western medicine primary care settings. The validity of the 3-domain scaling structure needs further evaluation.

Antihypertensive treatment using an angiotensin receptor blocker and a thiazide diuretic improves patients' quality of life: the Saga Challenge Antihypertensive Study (S-CATS)

The aim of the Saga Challenge Antihypertensive Study (S-CATS), a single-arm, prospective and multi-center trial, was to evaluate the effectiveness of combined antihypertensive treatment with losartan and hydrochlorothiazide (HCTZ). Enrolled in the study were a total of 161 patients with hypertension, who in spite of treatment with an angiotensin receptor blocker (ARB) alone or an ARB and calcium channel blocker (CCB), had not been able to reach blood pressure control goals set by the Japanese Society of Hypertension Guidelines (JSH 2004). The ARBs were replaced with a combination pill containing losartan (50 mg) and HCTZ (12.5 mg), and this treatment was continued for 3 months. This change in therapy resulted in significant decreases in systolic (158±14 to 137±15 mm Hg, P<0.001) and diastolic (85±11 to 76±10 mm Hg, P<0.001) blood pressure and heart rate (73±3 to 72±3) during the study. The patients' quality of life (QOL) score, the EuroQol 5 dimensions (EQ-5D) and the visual analog scale (VAS) (n=96; 70.0 (68.8-80.0) to 80.0 (70.0-90.0), P<0.01) all improved significantly. Another QOL score, the hypertension symptom score (HSS), which we originally developed for the S-CATS trial, decreased significantly (n=93; 4.0 (1.0-9.0) to 2.0 (1.0-8.0), P<0.05). The Pittsburgh sleep quality index (PSQI), which is a psychometric assessment of subjective sleep quality, also decreased significantly (n=45; 4.0 (2.0-7.0) to 3.0 (2.0-5.0), P<0.05). There was a significant correlation between a change in HSS (baseline value -3-months value) and a decrease in systolic blood pressure (n=93; R=0.241, P<0.05). These results suggest that an anti-hypertensive treatment combined with an ARB and a thiazide diuretic may improve patients' QOL, including sleep quality.

13 years of cultured limbal epithelial cell therapy: a review of the outcomes

The cornea is the clear tissue at the front of the eye which enables the transmission of light to the retina for normal vision. The surface of the cornea is composed of an epithelium which is renewed by stem cells located at the periphery of the cornea, a region known as the limbus. These limbal stem cells can become deficient as a result of various diseases of the eye's surface, resulting in the blinding disease of limbal stem cell deficiency. The treatment of this disease is often difficult and complex. In 1997, it was proposed that a small amount of limbal tissue containing limbal stem cells could be culture expanded and then transplanted. Since then various case reports and case series have been reported showing promising results. Here, we review the outcomes of this procedure over the past 13 years with the aim of highlighting the best culture and surgical techniques to date.

Statistical, practical, clinical, and personal significance: definitions and applications in speech-language pathology

PURPOSE

To discuss constructs and methods related to assessing the magnitude and the meaning of clinical outcomes, with a focus on applications in speech-language pathology.

METHOD

Professionals in medicine, allied health, psychology, education, and many other fields have long been concerned with issues referred to variously as practical significance, clinical significance, social validity, patient satisfaction, treatment effectiveness, or the meaningfulness or importance of beyond-clinic or real-world treatment outcomes. Existing literature addressing these issues from multiple disciplines was reviewed and synthesized.

CONCLUSIONS

Practical significance, an adjunct to statistical significance, refers to the magnitude of a change or a difference between groups. The appropriate existing term for the interpretation of treatment outcomes, or the attribution of meaning or value to treatment outcomes, is clinical significance. To further distinguish between important constructs, the authors suggest incorporating as definitive the existing notion that clinical significance may refer to measures selected or interpreted by professionals or with respect to groups of clients. The term personal significance is introduced to refer to goals, variables, measures, and changes that are of demonstrated value to individual clients.

The MOXFQ patient-reported questionnaire: assessment of data quality, reliability and validity in relation to foot and ankle surgery

Previously validated for hallux valgus surgery, the Manchester-Oxford Foot Questionnaire (MOXFQ) is here evaluated for use with different regions of the foot and ankle. The study recruited 671 consecutive patients (87.8% of those eligible), mean age 52.8 years, 64% female, who completed the MOXFQ and SF-36 general health survey before foot or ankle surgery. Surgeons completed the American Orthopaedic Foot & Ankle Society (AOFAS) scales and indicated that the patients' main regions for surgery were: Hallux 210 (31.3%), Lesser toes 119 (17.7%), Mid foot 22 (3.3%), Ankle/hind foot 311 (46.3%), Multiple/whole foot 9 (1.3%). Individual MOXFQ items were assessed in terms of response rate and floor/ceiling effects, with the validity of the three MOXFQ scales (Walking/standing, Pain, and Social interaction) being assessed in terms of item-total correlations, internal and test-retest reliability, and construct validity. MOXFQ item response rates were high (all >98%). Cronbach's alphas of >0.7 confirmed internal consistency of all three scales. Test-retest ICCs were all ≥0.89. Correlations of >0.4 obtained with related SF-36 and AOFAS scales supported a priori hypotheses. Good measurement properties are confirmed for the MOXFQ in the context of baseline assessment of patients receiving surgery for a variety of foot or ankle problems.

Preoperative symptoms of irritable bowel syndrome predict poor outcome after laparoscopic cholecystectomy

BACKGROUND

Laparoscopic cholecystectomy (LC) is the accepted treatment for symptomatic cholelithiasis. This study examines the effect LC has on quality of life (QOL) and gastrointestinal (GI) symptoms and determines whether patients with symptoms of irritable bowel syndrome (IBS) gain the same benefit as those without.

METHODS

A total of 158 patients who underwent LC for symptomatic gallstones were recruited to this prospective observational study. IBS Manning scores were calculated and QOL was measured using the Gastrointestinal Quality of Life Index (GIQLI) preoperatively, at 6 weeks, 3 months, and 2 years postoperatively. Linear regression analysis was used to identify preoperative symptoms that predict outcome.

RESULTS

One hundred twelve patients had sufficient data sets for inclusion. Patient's GIQLI scores were calculated for the four time points in the study. The mean preoperative score was 88.8 ± 1.3 (61.7% of 144, the highest score possible) and improved 6 weeks after surgery to 105.5 ± 1.3 (p < 0.001). This improvement was maintained at 3 months, but at 2 years analysis showed regression toward the baseline of 7.6 ± 2.3 (p = 0.003) points. There was a negative correlation of -5.2 ± 1.29 (p < 0.001) points between each Manning symptom and QOL scores. The largest effect was seen in patients describing loose bowel movement with the onset of pain. Patients with this symptom had a -17.3 ± 4.6 (p < 0.001) lower global QOL score.

CONCLUSIONS

Patients with symptoms of IBS indicated by the Manning criteria show less improvement in quality of life after laparoscopic cholecystectomy for gallstones.

The impact of change in visual field on health-related quality of life the los angeles latino eye study

PURPOSE

To assess the impact of change in visual field (VF) on change in health-related quality of life (HRQoL) at the population level.

DESIGN

Prospective cohort study.

PARTICIPANTS

Three thousand one hundred seventy-five Los Angles Latino Eye Study participants.

METHODS

Objective measures of VF and visual acuity and self-reported HRQoL were collected at baseline and at the 4-year follow-up. Analysis of covariance was used to evaluate mean differences in change of HRQoL across severity levels of change in VF and to test for effect modification by covariates.

MAIN OUTCOME MEASURES

General and vision-specific HRQoL.

RESULTS

Of 3175 participants, 1430 (45%) showed a change in VF (≥1 decibel [dB]) and 1715 (54%) reported a clinically important change (≥5 points) in vision-specific HRQoL. Progressive worsening and improvement in the VF were associated with increasing losses and gains in vision-specific HRQoL for the composite score and 10 of its 11 subscales (all P(trend)<0.05). Losses in VF of more than 5 dB and gains of more than 3 dB were associated with clinically meaningful losses and gains in vision-specific HRQoL, respectively. Areas of vision-specific HRQoL most affected by greater losses in VF were driving, dependency, role-functioning, and mental health. The effect of change in VF (loss or gain) on mean change in vision-specific HRQoL varied by level of baseline vision loss (in VF, visual acuity, or both) and by change in visual acuity (all P(interaction)<0.05). Those with moderate or severe VF loss at baseline and with a more than 5 dB loss in VF during the study period had a mean loss of vision-specific HRQoL of 11.3 points, whereas those with no VF loss at baseline had a mean loss of 0.97 points. Similarly, with a more than 5 dB loss in VF and baseline visual acuity impairment (mild or severe), there was a loss in vision-specific HRQoL of 10.5 points, whereas with no visual acuity impairment at baseline, there was a loss of vision-specific HRQoL of 3.7 points.

CONCLUSIONS

Both losses and gains in VF produce clinically meaningful changes in vision-specific HRQoL. In the presence of pre-existing vision loss (VF and visual acuity), similar levels of VF change produce greater losses in QOL.

Health-related quality of life in patients with Chagas disease

INTRODUCTION: Chagas disease (ChD) is a chronic illness related to significant morbidity and mortality that can affect the quality of life (QoL) of infected patients. However, there are few studies regarding QoL in ChD. The objectives of this study are to construct a health-related QoL (HRQoL) profile of ChD patients and compare this with a non-ChD (NChD) group to identify factors associated with the worst HRQoL scores in ChD patients. METHODS: HRQoL was investigated in 125 patients with ChD and 21 NChD individuals using the Medical Outcomes Study 36-item Short-Form (SF-36) and the Minnesota Living with Heart Failure Questionnaire (MLWHFQ). Patients were submitted to a standard protocol that included clinical examination, ECG, Holter monitoring, Doppler echocardiogram and autonomic function tests. RESULTS: HRQoL scores were significantly worse among the ChD group compared to the NChD group in the SF-36 domains of physical functioning and role-emotional and in the MLWHFQ scale. For the ChD group, univariate analysis showed that HRQoL score quartiles were associated with level of education, sex, marital status, use of medication, functional classification and cardiovascular and gastrointestinal symptoms. In the multivariate analysis, female sex, fewer years of education, single status, worst functional classification, presence of cardiovascular and gastrointestinal symptoms, associated illnesses, Doppler echocardiographic abnormalities and ventricular arrhythmia detected during Holter monitoring were predictors of lower HRQoL scores. CONCLUSIONS: ChD patients showed worse HRQoL scores compared to NChD. For the ChD group, sociodemographic and clinical variables were associated with worst scores.

Cross-cultural adaptation and validation with reliability, validity, and responsiveness of the Italian version of the Oxford Hip Score in patients with hip osteoarthritis

PURPOSE

The purpose of this study was to translate the Oxford Hip Score (OHS) into Italian and to evaluate the psychometric properties by testing the feasibility, internal consistency, reproducibility, construct validity, and responsiveness in patients with hip osteoarthritis (OA).

METHODS

The OHS Italian version was developed and evaluated in Italian-speaking patients with hip OA. The psychometric properties assessed were feasibility with floor and ceiling effect; internal consistency with Cronbach's Alpha; reproducibility with intraclass correlation coefficient (ICC); construct validity with evaluating correlation with the SF-36 and visual analogue scale (VAS) for pain; responsiveness to intra-articular hyaluronate injections. The standardized effect size (ES) and standardized response mean (SRM) were also evaluated.

RESULTS

A total of 96 patients were recruited (mean age 62.7 ± 5.8 years, range 49-77). No floor or ceiling effect was observed prior to or after treatment with HA injections. Cronbach's alpha value was 0.85 at baseline and 0.89 after treatment. The reproducibility was good with an ICC of 0.89. A strong correlation was found between OHS, VAS, and some SF-36 subscales, indicating good cross-sectional and longitudinal construct validity. The mean OHS improved from 16.4 ± 5.8 to 28.0 ± 9.0 after hyaluronate injections (P < 0.01). The ES and SRM values were 1.98 and 1.12, respectively.

CONCLUSIONS

The Italian OHS questionnaire is valid, reliable, and responsive for use in Italian patients with symptomatic hip OA receiving hyaluronate injections.
