Environmental health knowledge and competences in Basque health workers. A comparison of different professional profiles.

Environmental exposures are responsible for a quarter of morbidity and mortality rates globally. Primary care professionals work in a privileged position to detect and intervene on environmental health matters. Nevertheless, due to lack of specific training, international literature shows that primary care health professionals have limited skills to deal with those. The objectives of this study were to assess the levels of environmental health (EH) knowledge and competence of a sample of 446 health professionals and students in the Basque Country and explore the presence that EH has on their daily practice. Only a very small proportion of participants had received training and took environmental clinical history regularly. Participants were confident to deal, and actually dealt, with tobacco, pollen and sun exposures but less able to address topics like biomarkers, pesticides and endocrine disruptors. Finally, and in accordance to previous works, we found moderate levels of EH knowledge and skills in our sample, and observed that nurses and nursing students reported higher EH skills than other professional profiles but scored lower in knowledge. Despite the manifold impacts of environmental exposures on health, interventions to strengthen health professionals' EH competence are required.

Use of health care services according to functional performance in community-dwelling older adults in Spain. An approach using GAMLSS models.

Functional performance in older adults is a predictor of survival and other health outcomes and its measurement is highly recommended in primary care settings. Functional performance and frailty are closely related concepts, and frailty status is associated with the use of health care services. However, there is insufficient evidence on the utilization of services profile according to the functional performance of older adults. The aim of this study was to assess the relationship between functional performance and the use of a wide range of health services in community-dwelling older adults. Generalized additive models for location, scale and shape were used to study these complex data of services utilization, from primary to hospital care. A total of 749 participants from two Spanish regions were followed up for 2 years. Of those, 276 (37%) presented low functional performance and 473 (63%) normal performance according to the Timed Up and Go test. The results showed that even after adjusting for burden of comorbidity and polypharmacy, participants with low functional performance used primary and secondary care health services more intensively, visited emergency rooms more often, and were hospitalized more frequently and for longer periods of time. A negative binomial distribution and a variant thereof were found to be the best models to describe health service utilization data. In conclusion, functionality should be considered as an important health indicator for tailoring the provision of health services for older adults.

Multimorbidity and functional status in older people: a cluster analysis.

PURPOSE: Multimorbidity and frailty are complex conditions often present in older people. The aim of this study was to identify clusters of chronic diseases in robust and frail individuals and compare sociodemographic and health characteristics between these clusters. METHODS: This cross-sectional study used information from electronic health records and a baseline assessment, which included the Timed Up and Go test of physical performance as a measure of frailty. Multiple correspondence and cluster analyses were performed to identify groups. RESULTS: A total of 813 individuals (55.1% women; mean age 77.4 years, SD = 5.0) were studied. Frail individuals (n = 244) were older and had a poorer health status than robust individuals (n = 569). Three clusters were identified among the robust (RC1, n = 348; RC2, n = 139 and RC3, n = 82) and four among the frail individuals (FC1, n = 164; FC2, n = 23; FC3, n = 44 and FC4, n = 13). The RC1 and FC1 had a better health status (specifically, less polypharmacy, lower chronic disease burden and better self-perceived health) than RC2-RC3 and FC2-FC3-FC4, respectively. Diseases associated with mobility limitation and limb pain were more common in RC2 and FC2 than in the other clusters. Cardiovascular diseases and risk factors were more prevalent in RC3 and FC3. Among the frail a new cluster emerged, FC4, containing individuals with higher rates of cognitive and eye problems and a clearly poor health status. CONCLUSION: This exploratory study may provide relevant information for the clinical management of older patients with multimorbidity, even though the chronic disease clusters identified were similar in robust and frail individuals.

Description of frail older people profiles according to four screening tools applied in primary care settings: a cross sectional analysis.

BACKGROUND: Regarding the health care of older populations, WHO recommends shifting from disease-driven attention models towards a personalized, integrated and continuous care aimed to the maintenance and enhancement of functional capacities. Impairments in the construct of functional intrinsic capacity have been understood as the condition of frailty or vulnerability. No consensus has been yet reached regarding which tools are the most suitable for screening this kind of patients in primary care settings. Tools based on the measurement of functional performance such as Timed up and go test (TUG), Short Physical Performance battery (SPPB), self-completed questionnaires like Tilburg Frailty Indicator (TFI) and clinical judgement, as the Gerontopole Frailty Scale (GFS) may be adequate. The objective of this work is to describe and compare characteristics of community-dwelling individuals identified as vulnerable or frail by four tools applied in primary care settings. METHODS: Cross sectional analysis developed in primary care services in two regions of Spain. Community-dwelling independent individuals aged 70 or more willing to participate were recruited and data was collected via face-to-face interviews. Frailty was assessed by TUG, SPPB, TFI and GFST. Also socio-demographic characteristics, lifestyle habits and health status data (comorbidities, polypharmacy, self-perceived health), were collected. Multiple correspondence analysis (MCA) and cluster analysis were used to identify groups of individuals with similar characteristics. RESULTS: Eight hundred sixty-five individuals were recruited, 53% women, with a mean age of 78 years. Four clusters of participants emerge. Cluster 1 (N = 263) contained patients categorized as robust by most of the studied tools, whereas clusters 2 (N = 199), 3 (N = 183) and 4 (N = 220) grouped patients classified as frail or vulnerable by at least one of the tools. Significant differences were found between clusters. CONCLUSIONS: The assessed tools identify different profiles of patients according to their theoretical construct of frailty. There is a group of patients that are identified by TUG and SPPB but not by GFS or TFI. These tools may be useful in primary care settings for the implementation of a function- driven clinical care of older patients.

[Evaluation of an educational intervention and a structured review of polypharmacy in elderly patients in Primary Care]. / Evaluación de una intervención formativa con revisión estructurada de la medicación en pacientes mayores polimedicados en Atención Primaria.

BACKGROUND AND OBJECTIVE: Several interventions have been shown to reduce polypharmacy and potentially inappropriate prescription (PIP). The objective of the study was to evaluate the number of drugs and PIP before and after an educational intervention with the Primary Care physician (PCP), with electronic identification of PIP and structured medication review, in elderly patients with excessive polypharmacy (≥10 drugs). MATERIAL AND METHODS: A before-after intervention study was conducted in the Gipuzkoa district of Osakidetza (Basque Country Health System), in a random sample of patients older than 80 years taking ≥ 10 drugs, and whose PCP attended training sessions. Primary outcomes: change in the number of drugs and PIP, registered in computerised health records. SECONDARY OUTCOMES: benefit/risk ratio assessed by the PCP, safety problems, and therapeutic decision. RESULTS: Of the 591 eligible patients, 88 were excluded (41: PCP did not attend training sessions, 47: death/transfer/admission), including a total of 503 patients with mean age of 84.9 years, with 67.7% women. The mean number of drugs and PIP per patient decreased significantly, -0.88 (95% CI: -1.04 to -0.72) and -0.19 (95% CI: -0.29 to -0.09), respectively (p<.0001), with a 25.8% reduction in the number of patients with excessive polypharmacy. SECONDARY OUTCOMES: data collection sheets of 365 patients and 4,168 prescriptions were collected. The benefit-risk ratio was favourable for 75% of the prescriptions, with the most frequent decision being to maintain them (83%). Among the 911 prescriptions with an unfavourable/uncertain benefit/risk ratio, 47.3% were maintained. CONCLUSIONS: The intervention is associated with a reduction in excessive polypharmacy and PPI under real-world conditions.

Dietary Patterns and Their Relationship with Frailty in Functionally Independent Older Adults.

The impact of dietary patterns rather than single foods or nutrients on health outcomes is increasingly recognized. This cross-sectional study examines the dietary patterns of 527 non-institutionalized functionally independent older people aged ≥70 years from Gipuzkoa (Spain). Sociodemographic characteristics, health status, anthropometric measures and dietary data are collected. Multiple correspondence analysis (MCA) and cluster analysis are performed to identify dietary patterns and groups of individuals. Frequency of selected food items and compliance with food recommendations are included in the MCA. A high proportion of the sample population are overweight or obese, whereas only 3.3% are at risk of malnutrition (determined with the Mini Nutritional Assessment). Frail individuals (n = 130), measured with the Timed-Up and Go test are older, have a lower educational level, are more obese, present a poorer health status (more depressive symptoms, polypharmacy and falls, among others) and worse compliance with food recommendations than robust individuals (n = 392). Three groups of individuals are identified: cluster one (n = 285), cluster two (n = 194) and cluster three (n = 48). A gradient of increasing frailty and poorer health status is observed from cluster one to cluster three. The latter also shows the poorest dietary pattern, regarding dietary recommendations. The use of an easy-to-use tool to assess diet allows detection of differences among the three clusters. There is a need to increase awareness on the implementation of nutritional screening and a subsequent dietary assessment in primary care settings to provide nutritional care to elder, and moreover, frail individuals.

Health-related quality of life and associated factors in functionally independent older people.

BACKGROUND: Health-related quality of life (HRQL) is a key indicator of elderly people's health status that can be affected by different factors. However, little is known about which variables are associated with it in functionally independent elderly people. The aim of this project was to study HRQL and a wide variety of health, lifestyle, social and contextual aspects and their relation to HRQL in a sample of functionally independent, non-cognitively impaired community-dwelling adults, over 65 years of age, from a northern region of Spain. METHODS: A cross-sectional study for which data was collected by face-to-face interviews with the selected individuals. HRQL was measured with the EuroQol-5D scale, consisting of a 5 item descriptive system and a visual analogue scale (VAS). VAS values lower than 70 were considered poor HRQL. Binary logistic regression was used to identify factors related to the outcome. RESULTS: Six hundred and thirty-four individuals were included in the study. The mean age was 74.8 (SD 6.7) years, 55% of the participants were women and 46% rated their HRQL as poor. Several variables were found to be significantly associated with a poor HRQL in the multivariate model, adjusted for age and sex: polypharmacy (OR: 2.32, 95% CI: 1.62-3.31), the presence of sensory impairment (OR: 1.83, 95% CI: 1.24-2.69), not being engaged in cognitively stimulating activities (OR: 2.51, 95% CI: 1.03-6.16), or in group social activities (OR: 1.57, 95% CI: 1.11-2.22), low level of social support (OR: 3.12, 95%CI: 1.78-5.46) and the presence of obstacles in the closest home environment (OR: 1.83, 95%CI: 1.11-3.02). CONCLUSIONS: The study identified a set of health, social and contextual variables as strongly related to HRQL in functionally independent community-dwelling older people. The results highlight the multidimensional nature of HRQL. They also reveal the importance of a comprehensive assessment of HRQL when designing adequate health-related programmes aiming to enhance active and healthy ageing and delay the onset of dependence.

Patient self-report section of the ASES questionnaire: a Spanish validation study using classical test theory and the Rasch model.

BACKGROUND: The aim of the current study was to validate the self-report section of the American Shoulder and Elbow Surgeons questionnaire (ASES-p) into Spanish. METHODS: Shoulder pathology patients were recruited and followed up to 6 months post treatment. The ASES-p, Constant, SF-36 and Barthel scales were filled-in pre and post treatment. Reliability was tested with Cronbach's alpha, convergent validity with Spearman's correlations coefficients. Confirmatory factor analysis (CFA) and the Rasch model were implemented for assessing structural validity and unidimensionality of the scale. Models with and without the pain item were considered. Responsiveness to change was explored via standardised effect sizes. RESULTS: Results were acceptable for both tested models. Cronbach's alpha was 0.91, total scale correlations with Constant and physical SF-36 dimensions were >0.50. Factor loadings for CFA were >0.40. The Rasch model confirmed unidimensionality of the scale, even though item 10 "do usual sport" was suggested as non-informative. Finally, patients with improved post treatment shoulder function and those receiving surgery had higher standardised effect sizes. CONCLUSIONS: The adapted Spanish ASES-p version is a valid and reliable tool for shoulder evaluation and its unidimensionality is supported by the data.

Self-perceived health in functionally independent older people: associated factors.

BACKGROUND: Self-perceived health (SPH) is a powerful indicator of the health status of elderly people. This issue has been widely studied in oldest populations considering altogether functionally independent and dependent individuals. The objective of this study was to describe SPH and to identify the main factors that have an impact on SPH in a sample of functionally independent community-dwelling older adults. METHODS: For this cross-sectional study, face-to-face interviews were carried out with non-institutionalized functionally independent older individuals in a northern region of Spain. Participants were asked: "Overall, you would say that your health is excellent, very good, good, fair or poor?". SPH responses were grouped in two categories: good and poor. Binary logistic regression was used to identify factors associated with poor SPH. RESULTS: A sample of 634 individuals was studied, of whom 55 % were women. The mean age was 74.8 (SD 6.7) years. About 18 % of the respondents rated their health as poor. In the multivariate model adjusted for age and sex, reported poor health was significantly associated with polypharmacy (≥3 drugs per day) (OR: 5.76, 95 % CI: 3.60-9.18), the presence of sensory impairment (OR: 1.87, 95 % CI: 1.15-3.04), bad sleep quality (OR:1.82, 95 % CI: 1.02-3.28), a bad nutrition pattern (OR: 2.37, 95 % CI: 1.08-5.21), not engaging in cognitively stimulating activities (OR: 4.08, 95 % CI: 1.64-10.20), or group social activities (OR: 2.62, 95 % CI: 1.63-4.23). CONCLUSIONS: The study indicates that several health and social variables are strongly related to SPH in independent community-dwelling older adults. This finding highlights the need for thorough assessment of factors related to SPH in older independent adults, this being essential to develop health-related programmes for promoting active and healthy ageing and to delay the onset of dependence in this population.

Wrist fractures and their impact in daily living functionality on elderly people: a prospective cohort study.

BACKGROUND: Wrist fractures are the most common arm fractures in older adults. The impact of wrist fractures on daily functionality has been less studied than that of other types and so, less is known about the complexity of factors related to the functional impact of these fractures. This study is aimed to assess the role of individual and health care factors and its association with daily living functional changes after a wrist fracture. METHODS: A prospective cohort of patients aged 65 or more, affected by a fracture due to a fall, was conducted. These patients were identified at the emergency rooms of the six participating hospitals. As independent factors, the following were studied: socio-demographic data, characteristics of the fracture, health-related quality of life, wrist function and provided treatment. The main outcome was functional status measured by the Barthel Index for daily living basic activities and the Lawton Instrumental Activities of Daily Living (IADL) Scale for daily living instrumental activities. Data were collected at baseline just after the fall and after six months of follow-up. Patients were considered to have deteriorated if their functional status as measured by Barthel Index or Lawton IADL scores decreased in a significant way during the six months of follow up. RESULTS: Barthel Index and/or Lawton IADL scores fell at six months after the fracture in 33% of participants. This functional decline was more frequent in patients with comorbidity (p < 0.0001), polypharmacy (p < 0.0001), low health-related quality of life prior to the fall (p < 0.0001) and lower educational level (p = 0.009). The derived multivariate models show that patients that become dependent six months after the fall, have advanced age, severe chronic diseases, low functional performance prior to the fracture, and repeated episodes of accidental falls. This profile is consistent with a frailty phenotype. CONCLUSIONS: Wrist fractures are associated to the occurrence of dependence, especially in frail patients. These patients could benefit from being identified at the time the fracture is treated, in order to tackle their complex needs and so, prevent some of the burden of dependence generated by these fractures.

Evaluation of shoulder-specific patient-reported outcome measures: a systematic and standardized comparison of available evidence.

BACKGROUND: The aim of this study was to perform a standardized and systematic evaluation of the available evidence on multi-item shoulder-specific patient-reported outcome measures that are applicable to a wide spectrum of disorders. MATERIALS AND METHODS: A systematic review was conducted in PubMed to identify articles with information regarding the development process, metric properties, and administration issues of shoulder-specific patient-reported outcome measures. Two experts independently reviewed all the articles identified for one instrument and applied the EMPRO (Evaluating Measures of Patient Reported Outcomes) tool, which was designed to assess the quality of attributes in a standardized way. An overall EMPRO score and 6 attribute-specific scores were calculated (range, 0-100) to describe the quality of instrument performance. RESULTS: We identified 11 instruments and 112 articles (2-30 articles per instrument). The American Shoulder and Elbow Surgeons (ASES) shoulder assessment, Simple Shoulder Test (SST), and Oxford Shoulder Score (OSS) were the best rated, with overall scores of 77.4 points, 72.6 points, and 69.7 points, respectively. They have been shown to be valid, reliable, and responsive, with a low administration burden. Acceptable results were also found for the Flexilevel Scale of Shoulder Function, Shoulder Pain and Disability Index, and Dutch Shoulder Disability Questionnaire, but some of their attributes need further evaluation. CONCLUSIONS: Current evidence supports the use of the ASES, SST, or OSS. We recommend the SST for longitudinal studies or clinical trials, the Dutch Shoulder Disability Questionnaire for clinical practice to minimize administration burden, and the ASES or OSS to discriminate among patients' or groups' evaluations at one point of time.

Impact of a self-care education programme on patients with type 2 diabetes in primary care in the Basque Country.

BACKGROUND: Type 2 diabetes mellitus (DM2) is a disease with high prevalence and significant impact in terms of mortality and morbidity. The increased prevalence of the disease requires the implementation of new strategies to promote patient self-management. The Spanish Diabetes Self-Management Program (SDSMP) has proven to be effective in other settings. The objective of this study is to assess its effectiveness in terms of care for DM2 patients in primary care settings within the Basque Health Service - Osakidetza (Spain). METHOD/DESIGN: This is a randomised clinical trial in which patients diagnosed with DM2, 18-79 years of age, from four health regions within the Basque Health Service will be randomised into two groups: an intervention group, who will follow the SDSMP, and a control group, who will receive usual care in accordance with the clinical guidelines for DM2 and existing regulations in our region. The intervention consists of 2,5 hour-group sessions once a week for six weeks. The sessions cover target setting and problem solving techniques, promotion of physical exercise, basic knowledge of nutrition, proper use of medication, effective communication with relatives and health professionals, and basic knowledge about DM2 and its complications. This content is complemented by educational material: books, leaflets and CDs. The primary outcome measure will be the change in glycated haemoglobin (HbA1c), and secondary outcome measures will include changes in levels of physical activity and intake of fruit and vegetables, cardiovascular risk, quality of life, self-efficacy, number of consultations and drug prescriptions. The results will be analysed 6, 12 and 24 months after the intervention. DISCUSSION: If the intervention were to be effective, the programme should be spread to the entire diabetic population in the Basque Country and it could also be applied for other diseases. TRIAL REGISTRATION: ClinicalTrials.gov identifier NCT01642394.

Applying a coping with stress questionnaire for cancer patients to patients with non-cancer chronic illnesses.

One of the few instruments to evaluate coping skills among patients with chronic illnesses is the Cuestionario de Afrontamiento al Estrés para Pacientes Oncológicos (CAEPO), created initially for cancer patients. We evaluate how well CAEPO applies to patients with non-cancer chronic illnesses. A total of 344 patients (115 with chronic hepatitis C, 120 with inflammatory bowel disease and 109 with recurrent vertigo) completed the CAEPO. Exploratory factor analysis and Cronbach's alpha provide only partial support for the seven factors suggested by the original CAEPO. A streamlined version with fewer dimensions and items may be a better solution for identifying coping strategies among these patients.

Use of the long and short forms of the depression in the medically ill questionnaire in a Spanish population.

This study sought to translate, using a back-translation procedure, and evaluate the psychometric characteristics of Depression in the Medically Ill questionnaire (DMI-18) and its short version (DMI-10) in a Spanish population. Patients with somatic disorders (N = 366) completed the translated DMI-18 and another depression questionnaire. Among these, 167 were also assessed by a mental health professional (gold standard) to test criterion validity. Furthermore, coefficient alpha for both the versions were high (>.90), and convergent validity assessed against the Beck Depression Inventory for Primary Care, the Hospital Anxiety and Depression Scale, and the Patient Health Questionnaire-9 was satisfactory (r > .74). Confirmatory factor analysis results supported the one-factor model. When compared with the gold standard, sensitivity and specificity were 93% and 73% for DMI-18 and 87% and 74% for DMI-10, respectively. Thus, both the versions are acceptable measures that can be used by nonpsychiatric professionals to detect affective comorbidities in their patients.

[Validation of a short form of the function dimension of the WOMAC questionnaire]. / Validación de una escala reducida de capacidad funcional del cuestionario WOMAC.

OBJECTIVE: The aim of this prospective study was to evaluate the validity, reliability and responsiveness of the Spanish version of the 7-item short-form of the function dimension of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). METHODS: We conducted a prospective 1-year cohort study that included 459 patients on the waiting list for total knee or hip replacement. The WOMAC and EQ-5D questionnaires were sent at four time points: baseline and at 3, 6 and 12 months post-surgery. Based on a previously shortened scale, we performed a validation process with Rasch analysis and agreement measured by Bland-Altman plots. RESULTS: The values of Spearman's rho and Lin concordance coefficients between the full and short-form ranged from 0.96 to 0.98. Differences were statistically significant (p < 0.001) among the three groups of severity measured by a item in the EQ-5D. The two Bland-Altman plots showed no systematic differences and agreement was not dependent on the severity score. The short form fitted the Rasch model. Cronbach's α coefficients were higher than 0.85. Responsiveness was higher than 1.27 and 1.72 in knee and hip replacement, respectively. CONCLUSIONS: The Spanish 7-item short form of the WOMAC function dimension is valid, reliable and responsive for patients with total joint replacement. The use of this version will reduce the burden on patients in both clinical studies and clinical practice.

Opioid use at the end of life and survival in a Hospital at Home unit.

BACKGROUND AND SIGNIFICANCE: Although opioids are commonly used to treat pain, dyspnea, and other symptoms at the end of life, little information is available on the safety and efficacy of the use of these medications in terminally ill patients in the home care setting. OBJECTIVES: To explore whether high doses of opioids, or increasing doses, influence survival in patients with terminal cancer in a Hospital at Home unit. METHODOLOGY: A retrospective cohort study. Clinical records of 223 oncologic patients admitted to the Hospital at Home unit of Hospital Galdakao-Usansolo from 2003 to 2007 and who died at home were reviewed. Demographic variables (age and gender) as well as clinical variables at the time of admission (Eastern Cooperative Oncology Group Performance Status scale, previous intake of opioids, type of cancer, use of coadjuvant drugs) and daily doses of morphine during the admission were recorded. Main outcomes were the number of days from the maximum dose of opioids administered to death and total length of survival during the admission. RESULTS: Median survival from day of maximum dose to death was longer for patients who received higher doses of opioids (6 days) than those who received lower doses (2 days; p = 0.010). These differences disappeared after adjusting by demographic and clinical variables (HR, 0.86; 95% CI, 0.62-1.18 [p = 0.338]). Patients who received more than twofold increases in their initial doses had longer median survival (22 days) than those who did not (9 days; hazard ratio [HR], 0.45; 95% confidence interval [CI], 0.34-0.60 [p < 0.0001]); these differences persisted after adjustment. CONCLUSIONS: Our results suggest that the use of opioids is safe in for use in Hospital at Home patients with cancer and is not associated with reduced survival.

Comparison of 3 systems for assigning priority to patients on waiting lists for cataract extraction.

OBJECTIVE: As the demand for cataract surgery grows, patients in some health care systems are assigned to a waiting list. Several explicit priority tools have been developed. We compared 3 of these: the IRYSS-Cataract Priority Score (ICPS), Catalan Agency for Health Technology Assessment and Research cataract priority system (CCPS), and Western Canada Waiting List project for cataract surgery (WCWL). DESIGN: Prospective cohort study. PARTICIPANTS: A total of 1723 consecutive patients awaiting cataract surgery at 5 hospitals. METHODS: The ICPS, CCPS, and WCWL were applied to these patients after the collection of data. The 3 prioritization systems were compared using correlation methods, 95% limits of agreement, and the kappa coefficient. RESULTS: Means and standard deviations for the different prioritization systems were 60.9 (22.2) for the ICPS, 35.7 (20.4) for the CCPS, and 25.7 (21.5) for the WCWL. Pearson's correlation coefficients were 0.56 between the ICPS and the CCPS, 0.62 between the WCWL and CCPS, and 0.71 between the ICPS and WCWL. The kappa value among them ranged from 0.13 to 0.40, and the intraclass correlation coefficients ranged from 0.31 to 0.55. CONCLUSIONS: These 3 prioritization tools showed acceptable correlations but assigned significantly different point scores to similar scenarios. This may have consequences when using these tools for managing a waiting list for cataract extraction.

Potential for 2 priority systems to be used as appropriateness of indication tools for cataract surgery.

OBJECTIVE: To test 2 systems developed to prioritize patients on waiting lists for cataract surgery, the Western Canadian Waiting List (WCWL), and the Catalan Agency for Health Technology Assessment and Research Cataract Priority System (CCPS), as tools for judging the appropriateness of the intervention. DESIGN: Cross-sectional study with follow-up. PARTICIPANTS: A total of 1723 prospective patients awaiting cataract extraction in 5 hospitals were included in the study. METHODS: Priority scores using the WCWL and the CCPS systems were calculated and compared with visual acuity (VA) and visual function, measured by the Visual Function-14 index, before and after surgery. The sensitivity of each priority system to different groups was evaluated using a validated appropriateness of indications tool for cataract extraction. One-way analysis of variance and the Jonckheere-Terpstra test were used to detect differences in group scores. Spearman correlation coefficients were also examined. RESULTS: The WCWL and CCPS systems produced different mean values according to the preoperative levels of VA and visual function (p < 0.0001). Neither system showed a significant difference in mean scores based on gains in VA and visual function. Both systems produced different mean scores according to the different groups of appropriateness set by the appropriateness of indications tool for cataract (p < 0.0001). CONCLUSIONS: Given that appropriateness tools should correlate with outcomes, we recommend using neither the WCWL nor the CCPS for appropriateness purposes. Incorporating new criteria into these systems may improve the correlation with important outcomes and their adequacy for use as appropriateness tools.

Added value of dynamic contrast-enhanced magnetic resonance imaging in predicting advanced stage disease in patients with endometrial carcinoma.

AIM: To assess the added value of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) in predicting advanced stage disease in patients with endometrial carcinoma. MATERIALS AND METHODS: Fifty patients with endometrial carcinoma underwent preoperative MRI assessment in a single gynecological cancer center during a 2-year period. Magnetic resonance imaging examinations included high-resolution sagittal, axial, and axial-oblique T2-weighted images (T2WI) of the pelvis, and axial T1-weighted images (T1WI) of the pelvis and upper abdomen followed by DCE-MRI using a multiphase 3-dimensional gradient refocused echo T1WI sequence. The T2W images were evaluated initially, and local and overall staging was assigned according to the FIGO classification. An identical scoring system was used to evaluate the combination of DCE-MRI and T2WI. The presence of potential pitfalls in the accurate assessment of depth of myometrial invasion (leiomyoma, adenomyosis, loss of junctional zone definition, polypoid tumor, poor tumor-to-myometrium contrast, and tumor extension to uterine cornu) was also recorded. Surgical histology constituted the standard of reference. RESULTS: The depth of myometrial invasion was correctly determined in 78% (39/50) of the cases on T2WI alone, increasing to 92% (46/50) with the addition of DCE-MRI (95% confidence interval for improvement, 4.4%-23.6%, P = 0.016). The addition of DCE-MRI led to the correct detection of deep myometrial invasion in all cases. Tumor extension to uterine cornu was the only variable significantly associated (P = 0.014) with incorrect estimation of depth of myometrial invasion. CONCLUSIONS: The addition of multiphase 3-dimensional DCE-MRI to T2WI can effectively assess the depth of myometrial invasion in endometrial carcinoma and may be a useful tool to guide the surgical approach.

A brief self-administered psychological intervention to improve well-being in patients with cancer: results from a feasibility study.

BACKGROUND: Patients with cancer have relatively high rates of anxiety and distress, adversely affecting their well-being and quality of life. Recent studies indicate that addressing these symptoms could result in better response to cancer treatment. Researchers have found that interventions that focus on increasing mental awareness and the frequency of positive experiences may have a greater impact on reducing psychological morbidity and increasing quality of life than interventions that target relief of psychological symptoms. AIM: To develop and test a brief, easy to use intervention that could improve well-being and quality of life in cancer patients. METHODS: We developed a simple well-being intervention that made few demands on patient time and required little training resource. Participants were randomly assigned to an intervention group or a deferred entry group. Measures of anxiety, depression, well-being and quality of life were administered at baseline and at follow-ups. RESULTS: Twenty-two women with metastatic breast cancer and 24 men with metastatic prostate cancer were recruited from oncology clinics. Thirteen women and 14 men completed the study. Both qualitative and quantitative data showed that the intervention was acceptable to users. There was statistically significant improvement in quality of life scores on WHOQOL-BREF post-intervention (p=0.046). Compliance with the intervention was good. CONCLUSIONS: This brief well-being intervention appears to be a promising technique for improving quality of life of cancer patients, without making undue demands on staff resources or patient time. If further studies confirm its effectiveness, it could prove to be a cost-effective intervention.
