Postoperative Endophthalmitis in Immediate Sequential Bilateral Cataract Surgery: A Nationwide Registry Study.

PURPOSE: To report the incidence of postoperative endophthalmitis (PE) after immediate sequential bilateral cataract surgery (ISBCS) in Sweden. DESIGN: Retrospective cohort registry study. PARTICIPANTS: Patient data from 1 457 172 cataract extractions, including 1 364 934 unilateral surgeries and 92 238 ISBCSs. METHODS: Endophthalmitis cases reported to the Swedish National Cataract Register (NCR) during a 16-year period (2002-2017) were analyzed in comparison to all control cases with regard to patient characteristics, surgical technique, and capsule complication. MAIN OUTCOME MEASURE: Incidence and determinants for PE in ISBCS compared with unilateral surgeries. RESULTS: A total of 422 cases of PE were identified in 1 457 172 cataract extractions, yielding an overall incidence of 0.029% (95% confidence interval [CI], 0.0262-0.0317). For unilateral procedures, the rate was 0.0299% (95% CI, 0.0270-0.0328) or 408 cases in 1 364 934 operations, whereas that for ISBCS was 0.0152% (95% CI, 0.0072-0.0231) or 14 incidents in 92 238 operations (P = 0.01). In a logistic regression model including all cataract procedures, nonuse of intracameral (IC) antibiotics (ABs), capsule complication, age 85 years or more, male gender, and ocular comorbidity were found to be independent risk factors for PE. All these parameters were less frequent in ISBCS. Notwithstanding, in the same multivariate analysis, ISBCS in itself was associated with a significantly lower risk for PE. At follow-up, 5 of the 14 PE cases in the ISBCS cohort had a visual acuity (VA) of 20/200 or worse. Of these, one 93-year-old ISBCS patient developed bilateral infection. CONCLUSIONS: After ISBCS in Sweden, PE occurred once in 6600 surgeries. The risk of sustaining a final VA of 20/200 or less was 1 incident in 18 000 operated eyes. When counseling potential ISBCS patients about the risk of PE, it seems reasonable to state that the reported risk in the literature is lower than that with unilateral surgery but not negligible. Precautions remain necessary.

A Composite Risk Score for Capsule Complications Based on Data from the Swedish National Cataract Register: Relation to Surgery Volumes.

PURPOSE: To investigate case mix in relation to capsule complication, possible associations between case mix and operation volume, and change in case mix over time. DESIGN: Register-based study. PARTICIPANTS: Swedish patients who underwent cataract surgery between 2007 and 2016. METHODS: Demographics and data on ocular comorbidity, intraoperative difficulties, and capsule complications were registered from 2007 to 2016 and analyzed retrospectively in relation to coded data on individual surgeons' operation volume. Single factor analysis and logistic regression were performed, and a composite risk score was created. MAIN OUTCOME MEASURES: Risk of capsule complication, given as adjusted and composite odds ratio in relation to cataract surgery volume. RESULTS: Preoperative and intraoperative variables significantly associated with capsule complications were best-corrected visual acuity (BCVA) ≤0.1 (decimal, adjusted odds ratio [aOR], 1.82; P < 0.001); pseudoexfoliation (PEX) (aOR, 1.53; P < 0.001); sight-threatening ocular comorbidity other than age-related macular degeneration (AMD), diabetic retinopathy, glaucoma, or cornea guttata (aOR, 1.35; P = 0.006); use of Trypan blue (aOR, 1.76; P < 0.001); mechanical pupil dilation (aOR, 1.36; P = 0.024); and iris hooks at the rhexis margin (aOR, 6.99; P < 0.001). The composite risk score was 3.09 ± 6.40 (mean ± standard deviation) for patients with capsule complication and 1.28 ± 1.66 for uncomplicated procedures (P < 0.001). High-volume cataract surgeons (≥500 procedures yearly) had a significantly lower composite risk score (mean risk score ≤1.28; range, 1.01-2.02) compared with low- and medium-volume cataract surgeons (1.34 ± 0.56; range, 1.00-4.55 and 1.49 ± 0.58; range, 1.01-5.19), respectively. During the period 2007-2016, the proportion of patients aged >88 years, patients with BCVA ≤0.1, and patients with intraoperative difficulties decreased. CONCLUSIONS: Case mix, as calculated from a composite risk score based on preoperative and intraoperative parameters registered in the National Cataract Register (NCR), may contribute to the decrease in capsule complications from 2007 to 2016 and the lower complication rate observed in cases managed by high-volume cataract surgeons.

It's Not Just in the Walls: Patient and Staff Experiences of a New Spatial Design for Psychiatric Inpatient Care.

The environment in psychiatric inpatient care is key to patient recovery and staff job satisfaction. In this qualitative study of patient and staff experiences of a new spatial design in psychiatric inpatient care, we analysed data from 11 semi-structured interviews with patients and five focus group discussions with staff using qualitative content analysis. The new design contributed to feelings of safety and recovery, but patients and staff also reported some frustration and added stress. The results lead us to conclude that while the new spatial design improves some conditions for recovery and job satisfaction, the design itself is simply not enough. Changes in care environments require that both patients and staff be informed and involved in the renovation to ensure that patients feel respected and staff feel confident in using the new environment before and during treatment and follow-ups.

Cataract Surgery Volumes and Complications per Surgeon and Clinical Unit: Data from the Swedish National Cataract Register 2007 to 2016.

PURPOSE: To investigate the change in proportion of high-volume cataract surgeons during the period 2007 to 2016 and determine the impact of operation volume per surgeon and clinical unit on the rate of capsule complications. DESIGN: Retrospective, register-based study. PARTICIPANTS: Patients undergoing and surgeons performing cataract surgery at Swedish ophthalmologic departments 2007-2016. METHODS: All cataract procedures performed during a 10-year period were analyzed, and the change in operation volume of individual surgeons over time was determined. The yearly incidence of capsule complications was correlated to the operation volume of individual surgeons and clinical units. MAIN OUTCOME MEASURES: The number of cataract procedures yearly per surgeon and clinical unit, proportion of capsule complications, and change over time in operation volume and complication rate. RESULTS: The proportion of high-volume (≥500 procedures yearly) and very high-volume (≥1000 procedures yearly) surgeons increased from 15.0% to 34.0% and 2.1% to 10.9%, respectively (P < 0.001 for both categories). The proportion of all cataract procedures performed by high-volume surgeons was 36.9% in 2007, increasing to 68.1% in 2016. The yearly incidence of capsule complications decreased with increasing number of procedures; from a mean of 2.15% (standard deviation [SD], 3.17) for low-volume surgeons (10-99 procedures/year) to 1.32% (1.28) for medium-volume (100-499 procedures/year) surgeons and 0.59% (0.49) for high-volume surgeons (P = 0.016). Preoperative best-corrected visual acuity was significantly better in eyes operated on by high-volume and very high-volume cataract surgeons; the median best-corrected visual acuity (BCVA) was 0.5 (decimal) compared with a BCVA of 0.4 for patients who had their surgery performed by low- or medium-volume surgeons (overall P < 0.001). No significant difference in rate of capsule complications was seen between clinical units with high or low operation volume (P = 0.804). The overall incidence of capsule complications decreased gradually from 1.5% in 2007 to 0.8% in 2016, and preoperative BCVA increased from 0.46±0.10 (logarithm of the minimum angle of resolution) to 0.40±0.05 (P = 0.030). CONCLUSIONS: There is a strong association of rate of capsule complications with operation volume of individual surgeons but not with operation volume of individual clinical units. The decreased rate of capsule complications seen between 2007 and 2016 may be explained in part by a dramatic increase in the proportion of high-volume cataract surgeons during the period.

Dental Implant Quality Register-A possible tool to further improve implant treatment and outcome.

The Board of EAO (European Association for Osseointegration) has discussed an initiative to explore the conditions to establish a Dental Implant Register. It was suggested to bring this issue to the EAO Consensus Conference 2018 for a discussion and to possibly propose relevant and manageable parameters. This article presents some select examples from quality registers in the medical field. Based on the experience of established registers, essentially in the medical field, factors considered to be of importance, if and when establishing a Dental Implant Register are introduced and discussed.

Validity and test retest reliability of the vascular quality of life Questionnaire-6: a short form of a disease-specific health-related quality of life instrument for patients with peripheral arterial disease.

BACKGROUND: Many existing patient-reported outcome measures are extensive regarding both patient burden and administration, and in terms of analysing and reporting results. The VascuQoL-6 (VQ6) - a short version of the original Vascular Quality of Life Questionnaire (VascuQoL), a disease-specific instrument for peripheral arterial disease - was recently developed. However, the VQ6 has not yet been empirical tested with regard to content validity, construct validity and test retest reliability. Our aim was, therefore, to explore both the validity and the reliability of the VQ-6 in a target population with established peripheral arterial disease. METHODS: Two hundred patients treated at two vascular centres were consecutively recruited for the survey. Administered questionnaires included VQ6 and the Short Form Health Survey-36 (SF-36). Out of the 200 patients, 150 also received a second VQ6 questionnaire for a test-retest assessment. Further, a purposive sample of 22 patients consented to participate in cognitive interviews. All included patients suffer from peripheral arterial disease. The questionnaire data was tested by both Rasch analysis and traditional psychometric methods, while the cognitive interviews were analysed descriptively. RESULTS: The validity and reliability of the VQ6, as tested in a target population without the surrounding 19 items from the original VascuQoL, was high, in general, and a good fit to the Rasch model was observed. Further, an excellent internal consistency and significant correlations between comparable dimensions in SF-36 were demonstrated. In the test-retest analysis, the percentage agreement was somewhat poor (<70%) in the six items. However, no systematic disagreements between the two assessments were seen in any of the six items, and the test-retest assessment for the VQ6 sum score showed an acceptable intraclass correlation coefficient (0.86). Finally, all items in the VQ6 were considered as both understandable and relevant by the interviewed patients. CONCLUSIONS: The VQ6 has acceptable to good psychometric properties with regard to data quality, scale assumptions, targeting, validity and reliability. Further, VQ6 seems to be easy to use and comprehend within the target population of patients with PAD.

Inequity in waiting for cataract surgery--an analysis of data from the Swedish National Cataract Register.

BACKGROUND: Swedish Health and Medical Services act states that good care should be given to the entire population on equal terms. Still studies show that access to care in Sweden differ related to for example gender and socioeconomic variables. One of the areas in Swedish health care that has attracted attention for potential inequity in access is Cataract Extraction (CE). Previous studies of access to CE in Sweden show that female patients have in general poorer vision before they are operated and longer waiting times for CE than male patients. The aim of the study was to describe the waiting times in different patient groups with regards to visual acuity, gender, age, native country, educational level, annual income and whether the patient was retired or still working. METHODS: The study was designed as a register study of 102 532 patients who have had CE performed in Sweden 2010-2011. Linear regression was used to analyse the association between patient characteristics and waiting times. Mean waiting times for women and men were calculated for all groups. RESULTS: At significance level p < 0.05 longer waiting times corresponded to patients having good visual acuity, being of female gender, high age, retired, born outside the Nordic countries and having low income and education. Calculations of mean waiting times for all groups showed that women had longer waiting times than men. CONCLUSIONS: The differences between groups defined, for example, by gender, age, native country, income, education and retirement are statistically significant. We do not consider them as clinically significant, but we consider the consistent pattern that we have found noteworthy in relation to the principle of equity in health care.

Stress symptoms among adolescents before and after scoliosis surgery: correlations with postoperative pain.

AIMS AND OBJECTIVES: The aim of this study was to describe stress symptoms among adolescents before and after scoliosis surgery and to explore correlations with postoperative pain. BACKGROUND: Scoliosis surgery is a major surgical procedure. Adolescent patients suffer from preoperative stress and severe postoperative pain. Previous studies indicate that there is a risk of traumatisation and psychological complications during the recovery period. DESIGN: A prospective quantitative cohort study with consecutive inclusion of participants. METHODS: A cohort of 37 adolescent patients aged 13-18. To assess the adolescents' experiences before surgery and at six to eight months after surgery, the Trauma Symptom Checklist for Children - Alternative version, Youth Self-Report and Kiddie Schedule for Affective Disorder and Schizophrenia for children 12-18 were used. The Visual Analogue Scale was used for self-report of postoperative pain on day three. RESULTS: Rates of anxiety/depression and internalising behaviour were significantly higher before surgery than six months after. Preoperative anger, social problems and attention problems correlated significantly with postoperative pain on day three. At follow-up, postoperative pain correlated significantly with anxiety, social problems and attention problems. CONCLUSIONS: The results of this study indicate a need for interventions to reduce perioperative stress and postoperative pain to improve the quality of nursing care. RELEVANCE TO CLINICAL PRACTICE: Attention to preoperative stress and implementation of interventions to decrease stress symptoms could ameliorate the perioperative process by reducing levels of postoperative pain, anxiety, social and attention problems in the recovery period.

Evaluation of a Web-Based Training Program for Professional Carers Working With People With Learning Disabilities and Challenging Behavior: A Pilot Study with SSED-Design.

The interaction between people with intellectual disabilities and professional carers is often influenced by communicative difficulties contributing challenging behaviours. The aims of this study were to evaluate to a web-based training program aimed at improving carers' abilities to interact with people with learning disabilities who exhibit challenging behaviours and to explore carers' experiences of participating in such a program. A single-subject experimental design and mixed methods were used to integrate qualitative and quantitative data. Triangulation of questionnaires, interviews with carers, and assessments of one woman's behaviour was performed. The participants were professional carers aged 20 to 55 years. The web-based training program increased carers' abilities to handle challenging behaviours and decreased challenging behaviours in daily care. The program improved the opportunities to offer training to carers who work in community-based accommodations with limited time to receive training.

The changing pattern of cataract surgery indications: a 5-year study of 2 cataract surgery databases.

PURPOSE: The aim of this study was to describe changes over time in the indications and outcomes of cataract surgery and to discuss optimal timing for the surgery. DESIGN: Database study. PARTICIPANTS: Patients who had undergone cataract extraction in the Netherlands, Sweden, or Malaysia from 2008 through 2012. METHODS: We analyzed preoperative, surgical, and postoperative data from 2 databases: the European Registry of Quality Outcomes for Cataract and Refractive Surgery (EUREQUO) and the Malaysian National Cataract Registry. The EUREQUO contains complete data from the national cataract registries in the Netherlands and Sweden. MAIN OUTCOME MEASURES: Preoperative and postoperative corrected distance visual acuity, preoperative ocular comorbidity in the surgery eye, and capsule complications during surgery. RESULTS: There were substantial differences in indication for surgery between the 3 national data sets. The percentage of eyes with a preoperative best-corrected visual acuity of 20/200 or worse varied from 7.1% to 72%. In all 3 data sets, the visual thresholds for cataract surgery decreased over time by 6% to 28% of the baseline values. The frequency of capsule complications varied between the 3 data sets, from 1.1% to 3.7% in 2008 and from 0.6% to 2.7% in 2012. An increasing postoperative visual acuity was also seen for all 3 data sets. A high frequency of capsule complication was related significantly to poor preoperative visual acuity, and a high frequency of decreased visual acuity after surgery was related significantly to excellent preoperative visual acuity. CONCLUSIONS: The 5-year trend in all 3 national data sets showed decreasing visual thresholds for surgery, decreasing surgical complication rates, and increasing visual outcomes regardless of the initial preoperative visual level. Cataract surgery on eyes with poor preoperative visual acuity was related to surgical complications, and cataract surgery on eyes with excellent preoperative visual acuity was related to adverse visual results.

A qualitative study of young women's experiences of recovery from bulimia nervosa.

AIM: To describe experiences of recovery from bulimia nervosa among young adult women. BACKGROUND: Most studies into recovery from eating disorders focus on anorexia nervosa, although some include both anorexia and bulimia nervosa. Recovery has been described as beginning with renewed self-esteem. DESIGN: Qualitative interview study. METHODS: Fourteen women were invited to participate; five women, between 23-26 years of age, who assessed themselves as healthy for at least 2 years agreed to take part in narrative interviews. Tape-recorded interviews lasting 45-60 minutes (median 49 minutes) were conducted from February-April 2010 and transcribed verbatim. Data were analysed using qualitative content analysis. FINDINGS: The interviews revealed four themes in recovery from bulimia nervosa: feeling stuck in bulimia nervosa, getting ready to change, breaking free of bulimia nervosa and grasping a new reality, each comprising two or more subthemes. The process of recovery was not linear, but rather went back and forth between progress and relapse. The women expressed strong ambivalence about leaving the illness behind. An important part of their recovery was their ability to accept themselves. It was essential for their recovery to be supported in developing a unique explanation of the cause of their illness. CONCLUSION: Women's ability to recover from bulimia nervosa and take control over their lives is based on their self-efficacy. Effective care should therefore strive to strengthen women's beliefs in their own abilities, to instil hope for recovery and thus to bolster their self-efficacy.

Vascular Quality of Life Questionnaire-6 facilitates health-related quality of life assessment in peripheral arterial disease.

BACKGROUND: Most commonly used outcome measures in peripheral arterial disease (PAD) provide scarce information about achieved patient benefit. Therefore, patient-reported outcome measures have become increasingly important as complementary outcome measures. The abundance of items in most health-related quality of life instruments makes everyday clinical use difficult. This study aimed to develop a short version of the 25-item Vascular Quality of Life Questionnaire (VascuQoL-25), a PAD-specific health-related quality of life instrument. METHODS: The study recruited 129 individuals with intermittent claudication and 71 with critical limb ischemia from two university hospitals. Participants were a mean age of 70 ± 9 years, and 57% were men. All patients completed the original VascuQoL when evaluated for treatment, and 127 also completed the questionnaire 6 months after a vascular procedure. The VascuQoL-25 was reduced based on cognitive interviews and psychometric testing. The short instrument, the VascuQoL-6, was tested using item-response theory, exploring structure, precision, item fit, and targeting. A subgroup of 21 individuals with intermittent claudication was also tested correlating the results of VascuQoL-6 to the actual walking capacity, as measured using global positioning system technology. RESULTS: On the basis of structured psychometric testing, the six most informative items were selected (VascuQoL-6) and tested vs the original VascuQoL-25. The correlation between VascuQoL-25 and VascuQoL-6 was r = 0.88 before intervention, r = 0.96 after intervention, and the difference was r = 0.91 (P < .001). The Cronbach α for the VascuQoL-6 was .85 before and .94 after intervention. Cognitive interviews indicated that the responders considered all six items to be relevant and comprehensible. Rasch analysis was used to reduce response options from seven (VascuQoL-25) to four (VascuQoL-6). VascuQol-6 was shown to have high precision and discriminative properties. Item fit was excellent, with both "infit" and "outfit" between 0.7 and 1.3 for all six items. The standardized response mean after intervention was 1.15, indicating good responsiveness to clinical change. VascuQoL-6 results correlated strongly (r = 0.72; P < .001) with the actual measured walking ability (n = 21). CONCLUSIONS: VascuQoL-6 is a valid and responsive instrument for the assessment of health-related quality of life in PAD. The main advantage is the compact format that offers a possibility for routine use in busy clinical settings.

European registry for quality improvement in cataract surgery.

PURPOSE: A project aimed at creating a multi-national database for cataract and refractive surgery was initiated in 2008. The database was intended for learning and clinical improvement, not supervision. The project was co-funded by the European Union, under the Executive Agency for Health and Consumers and the European Society of Cataract and Refractive Surgeons (ESCRS) and supported by 11 national societies for cataract and refractive surgery. The purpose of this article is to describe the setup of the database and the ensuing achievements within cataract surgery after four years. DESIGN/METHODOLOGY/APPROACH: A web-based system was created for input and output of data, with a software interface to two databases, one for cataract surgery and one for refractive surgery. Data can be put in either manually through web forms or by transfer of data from existing national registries or large electronic medical record systems. Output of reports from the system or export of one's own data is available on the web. The data are anonymous to all users, with the sole exception that reporting surgeons and clinics have access to their own data. The system does not include any patient identification. FINDINGS: After four years, data from 16 countries have been entered into the system, including reports of more than 900,000 cataract extractions. The database has been used by individual clinics for benchmarking and clinical improvement work, and has also served as the basis for new clinical guidelines for cataract surgery. The ESCRS has guaranteed the sustainability of the database after the project period. ORIGINALITY/VALUE: A European quality registry with data input from surgeons and clinics in 16 European countries has been established. Close to one million surgeries have been entered into the system during the first four years. Evidence-based guidelines have been published based on data in the registry. The system is used for benchmarking by both experienced surgeons and trainees.

Endophthalmitis after cataract surgery and effect of different intracameral antibiotic regimes in Sweden 2011-2017: national registry study.

PURPOSE: To study the incidence, predictive factors, etiology, and visual consequences of postoperative endophthalmitis (PE) in relation to 3 intracameral (IC) antibiotic regimes. SETTING: Swedish National Cataract Register entries from 2011 through 2017. DESIGN: Observational retrospective study. METHODS: PE incidence, influencing factors, bacteriology, and visual outcome were analyzed regarding the 3 major prophylactic IC protocols. RESULTS: The overall incidence of PE was 0.023% or 177 cases in 764 513 cataract procedures. Analyzed per IC regime, the rates of PE were 0.024% (126 cases in 514 916 surgeries) for cefuroxime, 0.020% (25 cases in 122 340 surgeries) for moxifloxacin, and 0.017% (20 cases in 121 045 surgeries) for combined cefuroxime-ampicillin. Incidences were not statistically significantly different from one another. Gram-positive bacteria caused 89.0% of culture positive cases. Enterococci as pathogens were significantly more frequent with IC cefuroxime than with moxifloxacin, P = .006, or cefuroxime-ampicillin, P < .001, while streptococci other than enterococci were more common with moxifloxacin than with cefuroxime, P < .001. Bacterial susceptibility to the given antibiotics was demonstrated in 21.3% of PE cases treated with cefuroxime, which was statistically significantly lower than proportions found with cefuroxime-ampicillin, 60.0%, P = .015, or with moxifloxacin, 88.2%, P < .001. Visual outcome worse than 20/200 was similar in the groups ranging from 42.0% to 53.7%. CONCLUSIONS: No statistically significant differences in PE incidence or visual outcome results between treatment groups were demonstrated. However, differences in etiology and bacterial sensitivity were found between the prophylactic IC treatments.

Ten-year trends of immediate sequential bilateral cataract surgery (ISBCS) as reflected in the Swedish National Cataract Register.

PURPOSE: To analyse trends of ISBCS reported to the Swedish National Cataract Register (NCR) over a 10-year period. METHODS: Since 2010 the NCR contains social security number of all individuals in the list of parameters reported to NCR after each cataract procedure. Bilateral surgeries were mapped out using social security numbers. When dates of both-eye surgeries are identical for an individual it is classified as an immediate sequential bilateral cataract surgery (ISBCS). This study includes all data reported during the period 1st of January 2010 to 31st of December 2019. During the study period 113 cataract surgery clinics affiliated to the NCR reported their data on consecutive cataract cases. RESULTS: For the whole period 54 194 ISBCS were reported. The total number of bilateral cataract extractions was 422 300. There was a significant trend of increasing ISBCS over time with linear regression (Beta = 1.75, p < 0.001). In ISBCS the occurrence of an ocular comorbidity decreased over time. The use of a capsular tension ring was significantly more common in ISBCS than in delayed sequential bilateral cataract surgery (DSBCS). All other measures taken during surgery were more common in DSBCS. The use of multifocal IOL was significantly more frequent in ISBCS compared to DSBCS (p < 0.001). CONCLUSIONS: The use of ISBCS has increased over the study period. The operated eyes have less risk factors than eyes going through a DSBCS, but both ocular comorbidities and surgical complications occur in ISBCS eyes.

[2.6 million cataract surgeries: 31 years with the Swedish National Cataract Register 1992-2022]. / 2,6 miljoner kataraktoperationer.

This review summarizes data collected by the Swedish National Cataract Register (NCR), which by the end of 2022 contained data on more than 2.6 million cataract surgeries between 1992-2022. During these 31 years, the cataract surgery rate (CSR) rose from 3 700 to 14 407. The coverage of NCR is very high, including 93% of all cataract procedures in Sweden during the last decade. A clear trend is that the procedure is performed in eyes with increasingly high visual acuity. The proportion of patients with Snellen 0.5 or worse in the first eye at surgery has decreased from 88% in 2007 to 69% in 2022. Patient Reported Outcome Measures (PROM) have been registered with the Catquest-9SF questionnaire since 2008, demonstrating stable favorable outcomes. Surgical complications have decreased; endophthalmitis has decreased from 0.10% to below 0.02%, and posterior capsule rupture from 2.8% to 0.6%.

Analyzing patient-reported outcomes to improve cataract care.

PURPOSE: The purpose of this study was to analyze three models of how patient-reported outcome measures can be connected to clinical outcome measures in cataract surgery to identify opportunities for improvement of quality of care. METHODS: Three models were used to analyze the following questions: Is there a relationship between clinical parameters and patient-reported outcomes? (1) Is there a relationship between clinical parameters and a good or poor patient-reported outcome? (2) When and why do clinical and patient-reported outcomes diverge? (3) The study material to exemplify these models consisted of follow-up data on cataract extractions collected by the Swedish National Cataract Register in 2008 to 2011. Patient-reported outcome was measured using the Catquest-9SF questionnaire. A total of 9707 pairs of questionnaires completed before and after a cataract extraction were analyzed together with clinical data. RESULTS: Factors related to any change in patient-reported outcomes after surgery were the preoperative self-assessed visual function, the preoperative visual acuity in both eyes, the postoperative visual acuity, and ocular comorbidity. Factors related to poor patient-reported outcomes after surgery were good preoperative self-assessed visual functions, poor preoperative visual acuity in the better eye, ocular comorbidity, surgical complications, and large refractive deviation. Poor near vision after surgery was the main factor noted in situations where the clinical outcome was good and the patient-reported outcome was poor. Analyses 2 and 3 were the most useful analyses to give ideas for clinical improvement work. CONCLUSIONS: The best models to give ideas for improved quality of care by using a patient questionnaire in our study were analyzing the risk factors for a poor patient-reported outcome and analyzing the factors associated with disagreement between clinical outcomes and patient-reported outcomes.

Congenital cataract screening in maternity wards is effective: evaluation of the Paediatric Cataract Register of Sweden.

AIM: To study which eye-screening protocol prevails in Swedish maternity/neonatal wards, evaluate efficacy in a prospective study and compare results with earlier Swedish retrospective results. METHODS: Surveys were sent in 2006 to maternity/neonatal and women's health departments regarding screening policy. Response frequency was 96% (122/127). Data were derived from the Paediatric Cataract Register (PECARE), Sweden. All Swedish children diagnosed with congenital cataract and operated on before 1 year of age between January 2007 and December 2009 were included. Statistical comparison with earlier retrospective results was performed. RESULTS: Eye screening is a routine protocol at a rate of 90% of Swedish maternity wards. Sixty-one children were included in the study. An increase was shown in case referrals from maternity wards compared to 10 years ago (64% vs. 50%). Detection was performed within 6 weeks of age in 75% of the cases. A significant difference between the probabilities of early referral (0.38; p < 0.001, < 6 weeks of age) and early surgery (0.36; p < 0.001) (PECARE) was found in comparison with the historical data of no maternity-ward screening. Well-baby clinics were instrumental in early detection, as well. CONCLUSION: Eye screening in maternity wards is effective. Clear Swedish directives are to be preferred.
