OBJECTIVE: To study the visual acuity and astigmatism of persons undergoing cataract extraction by local surgeons in rural China. METHODS: Visual acuity, keratometry, and refraction were measured 10 to 14 months postoperatively for all cataract cases during 4 months in Sanrao, China. RESULTS: Among 313 eligible subjects, 242 (77%) could be contacted, of whom 176 (73%) were examined. Of those who were examined, mean +/- SD age was 69.3 +/- 10.5 years, 66.5% were female, 35 had been operated on bilaterally at Sanrao, and 85.2% had a preoperative presenting visual acuity of 6/60 or worse. Presenting and best-corrected postoperative acuity in the eye that was operated on were 6/18 or better in 83.4% and 95.7%, respectively. Among 27 fellow eyes operated on elsewhere, 40.7% had a presenting acuity of 6/18 or better and 40.7% were blind (P < .001). Mean +/- SD postoperative astigmatism did not differ between 211 eyes that were operated on (-1.13 +/- 0.84 diopters) and 109 eyes that were not (-1.13 +/- 1.17 diopters; P = .27). Presence of operative complications (8.5%) and older age were associated with worse vision; bilateral surgery was associated with better vision. CONCLUSIONS: These results confirm the effectiveness of skill transfer in this setting, with superior outcomes to most studies in rural Asia and to eyes in this cohort operated on at other facilities.

OBJECTIVE:
To study the postoperative visual function and uptake of refraction and second-eye surgery among persons undergoing cataract surgery in rural China.
METHODS:
Self-reported visual function was measured 10 to 14 months after surgery. Subjects with improvement of 2 or more lines with refraction were offered glasses, and those with significant cataract were offered second-eye surgery.
RESULTS:
Among 313 eligible subjects, 242 (77%) could be contacted; 176 (73%) of those contacted were examined. Interviewed subjects had a mean +/- SD age of 69.9 +/- 10.2 years, and 63.6% were female. The mean +/- SD visual function score was 88.4 +/- 12.3, higher than previously reported for cataract programs in rural China and significantly (P = .03) correlated with presenting vision. Forty-two percent of subjects had spectacles, more than half being reading glasses. Though 87% of subjects' vision improved with refraction, only 35% accepted prescriptions, the most common reason for refusal being lack of perceived need. Second-eye surgery was accepted by a total of 48% (85 of 176) of patients, cost being the biggest reason for refusal.
CONCLUSIONS:
Visual function was high in this cohort. Potential benefit of refraction and second-eye surgery was substantial, but uptake of services was modest. Programs to improve service uptake should focus on reading glasses and cost-reduction strategies such as tiered pricing.

PURPOSE: To determine the prevalence and impact on vision and visual function of ocular comorbidities in a rural Chinese cataract surgical program, and to devise strategies to reduce their associated burden. DESIGN: Cross-sectional cohort study. PARTICIPANTS: Persons undergoing cataract surgery by one of two recently trained local surgeons at a government-run village-level hospital in rural Guangdong between August 8 and December 31, 2005. INTERVENTIONS: Eligible subjects were invited to return for a comprehensive ocular examination and visual function interview 10 to 14 months after surgery. Prevalent ocular comorbid conditions were identified. MAIN OUTCOME MEASURES: Presenting and best-corrected vision, visual function, and treatability of the comorbidity. RESULTS: Of 313 persons operated within the study window, 242 (77%) could be contacted by telephone; study examinations and interviews were performed on 176 (74%). Examined subjects had a mean age of 69.4+/-10.5 years, 116 (66%) were female, and 149 (85%) had been blind (presenting vision < or = 6/60) in the operative eye before surgery. Among unoperated eyes, 89 of 109 (81.7%) had > or =1 ocular comorbidities, whereas for operated eyes the corresponding proportion was 72 of 211 (34.1%). The leading comorbidity among operated eyes was refractive error (43/72 [59.7%]), followed by glaucoma/glaucoma suspect (14/72 [19.4%]), whereas for unoperated eyes, it was cataract (80/92 [87.0%]), followed by refractive error (12/92 [13.0%]). Among operated eyes with comorbidities, 90.3% (65/72) had > or =1 comorbidities that were treatable. In separate models adjusting for age and gender, persons with > or =1 comorbidities in the operated eye had significantly worse presenting vision (P<0.001) than those without such findings, but visual function (P = 0.197) and satisfaction with surgery (P = 0.796) were unassociated with comorbidities. CONCLUSIONS: Ocular comorbidities are highly prevalent among persons undergoing cataract surgery in this rural Asian setting, and their presence is significantly associated with poorer visual outcomes. The fact that the great majority of comorbidities encountered in this program are treatable suggests that strategies to reduce their impact can be successful.

PURPOSE: To model the possible impact of using average-power intraocular lenses (IOLs) and evaluate the postoperative refractive error in patients having cataract surgery in rural China.SETTING: Rural Guangdong, China.METHODS: Patients having cataract surgery by local surgeons were examined and visual function was assessed 10 to 14 months after surgery. Subjective refraction at near and distance was performed bilaterally by an ophthalmologist. Patients had a target refraction of -0.50 diopter (D) based on ocular biometry.RESULTS: Of the 313 eligible patients, 242 (77%) could be contacted and 176 (74% of contacted patients, 56% overall) were examined. Examined patients had a mean age of 69.4 +/- 10.5 years. Of the 211 operated eyes, 73.2% were within +/-1.0 D of the target refraction after surgery. The best presenting distance vision was in patients within +/-1.0 D of plano and the best presenting near vision, in those with mild myopia (<-1.0 D to > or =2.0 D) (P= .005). However, patients with hyperopia (>+1.0 D) reported significantly better adjusted visual function than those with emmetropia or myopia (<-1.0 D). When the predicted use of an average-power IOL (median +21.5 D) was modeled, predicted visual acuity was significantly reduced (P= .001); however, predicted visual function was not significantly altered (P>.3).CONCLUSIONS: Accurate selection of postoperative refractive error was achieved by local surgeons in this rural area. Based on visual function results, aiming for mild postoperative myopia may not be suitable in this setting. Implanting average-power IOLs significantly reduced postoperative presenting vision, but not visual function.

AIM: To study patient sources of knowledge about cataract surgical services, and strategies for financing surgery in rural China. DESIGN: Cross-sectional case series. METHODS: Patients undergoing cataract surgery by local surgeons in a government, village-level facility in Sanrao, Guangdong between 8 August and 31 December 2005 were examined and had standardised interviews an average of 12 months after surgery. RESULTS: Of 313 eligible patients, 239 (76%) completed the questionnaire. Subjects had a mean (SD) age of 69.9 (10.2) years, 36.4% (87/239) were male, and 87.0% (208/239) had been blind (presenting visual acuity < or = 6/60) before surgery. Word-of-mouth advertising was particularly important: 198 (85.0%) of the subjects knew a person who had undergone cataract surgery, of whom 191 (96.5%) had had cataract surgery at Sanrao itself. Over 70% of subjects (166/239) watched TV daily, whereas 80.0% (188/239) "never" read the newspaper. Nearly two-thirds of suggestions from participants (n = 211, 59.6%) favoured either TV advertisements or word-of-mouth to publicise the programme. While the son or daughter had paid for surgery in over 70% of cases (164/233), the patient's having paid without help was the sole predictor of undergoing second-eye surgery (OR 2.27 (95% CI 1.01 to 5.0, p = 0.04)). DISCUSSION: Strategies to increase uptake of cataract surgery in rural China may benefit from enhancing word-of-mouth advertising (such as with pseudophakic motivators), using television advertising where affordable, and micro-credit or other programmes to enable patients to pay their own fees, thus increasing uptake of second-eye surgery.

AIM: To study the effect of posterior capsular opacification (PCO) on vision and visual function in patients undergoing cataract surgery in rural China, and to compare this with the effect of refractive error. METHODS: Patients undergoing cataract surgery in at least one eye by local surgeons in a rural setting between 8 August and 31 December 2005 were examined with slit lamp grading of PCO 10-14 months after surgery. Subjects with any PCO associated with best-corrected visual acuity of 6/7.5 or worse, or with grade 2+ or worse PCO without visual decrement, were offered YAG laser capsulotomy. Vision and self-reported visual function were assessed, and various demographic and clinical factors potentially associated with PCO were recorded. RESULTS: Of 313 patients operated on within the study window, 239 (76%) could be contacted by telephone; study examinations were performed on 176 (74%). Examined subjects had a mean (SD) age of 69.4 (10.5) years, 116 (67%) were female, and 149 (86%) had been blind (presenting visual acuity < or = 6/60) in the operated eye before surgery. PCO of grade 1 or above was present in 34 of 204 operated eyes (16.7%). Those with PCO had significantly worse presenting vision (p = 0.007) but not visual function (p>0.3) than those without PCO. Women had a significantly higher prevalence of PCO (20.9%) than did men (8.6%, p<0.05). Of 19 eyes undergoing capsulotomy with best-corrected visual acuity measured the next day, 13 (68%) improved by one or more lines, and seven (37%) improved by two or more lines. Despite a higher uptake of capsulotomy (95%) as opposed to refraction (35%) in this cohort, the yield in terms of eyes with poor presenting visual acuity (< 6/18) that could be improved was higher for refraction (26% = 9/35) than for capsulotomy (9% = 3/35). CONCLUSION: The prevalence of PCO and impact on vision and visual function in this cohort was modest 1 year after surgery. However, PCO prevalence increases with time. Follow-up of this cohort is underway to determine the effectiveness of this early intervention in identifying and treating subjects who will eventually experience clinically significant PCO.

OBJECTIVE: To assess the use of eye care and its predictors among diabetic patients in China. DESIGN: Cross-sectional, clinic-based study. PARTICIPANTS: Diabetic patients 18 years of age or older were recruited consecutively from an urban tertiary and community hospitals and from a rural clinic in Guangdong, China. METHODS: Information obtained by questionnaire and chart review included: demographic and socioeconomic status, knowledge about diabetic retinopathy (DR), and ocular and medical history. MAIN OUTCOME MEASURES: Self-reported or chart history of an eye examination ever or within the preceding 12 months. RESULTS: The participation rate among 889 eligible subjects was 92.7%. Among 824 participants (mean age, 62.6+/-12.9 years; 58.8% female), 550 (66.7%) had not been examined in the last year as recommended by the American Academy of Ophthalmology, and 356 (43.2%) had never been examined. For the rural hospital, these figures were 81.1% and 68.7%, respectively. In regression analyses, factors associated with having an eye examination in the last year were: attendance at urban hospitals (odds ratio [OR], 3.46 [P<0.001] and 1.76 [P = 0.021] for the tertiary and community hospitals, respectively, compared with the rural clinic), higher DR knowledge score (OR, 1.24; P = 0.001), greater concern about vision loss (OR, 1.22; P = 0.007), and recommendation of regular eye examinations by the provider (OR, 2.36; P = 0.011). Predictors of ever having an eye examination were similar. Monthly income and health insurance status were not predictive of being examined. CONCLUSIONS: These results suggest that the low proportion of diabetic receiving recommended annual eye examinations in China may be improved through patient and physician education.

OBJECTIVES:
To assess the use of eye care and its predictors among diabetic patients in Indonesia.
METHODS:
Diabetic patients aged 18 years and older were recruited consecutively from a university clinic and 2 community clinics in Jakarta, Indonesia. Information obtained by questionnaire and record review included demographic and socioeconomic status, knowledge about diabetic retinopathy, and ocular and medical history. The main outcome was self-reported or record history of an eye examination by an eye care professional with dilation of the pupil within the preceding year.
RESULTS:
Among 196 participants (mean [SD] age, 58.4 [9.4] years; 61.5% female), 166 (84.7%) had not undergone ocular examination in the last year, including 100 of 119 patients (84.0%) at the university clinic. Fewer than half (82 of 166 [49.4%]) of all patients reported being told of the need for eye examinations by their physician. In regression analyses, factors associated with having an eye examination were higher diabetic retinopathy knowledge score (odds ratio = 1.52; P = .01) and years since being diagnosed as having diabetes (odds ratio = 1.71 for third vs first tertile; P = .02). Education, income, health insurance status, and diagnosis of diabetic retinopathy were not predictive of examination. The most common reasons given by subjects for not having had eye examinations concerned lack of knowledge about the need for care (97 of 160 subjects [60.6%]), while financial barriers were cited by only 22 of 160 subjects (13.8%).
CONCLUSION:
The low proportion of diabetic subjects receiving recommended annual eye examinations in Indonesia might be improved through patient and physician education.

Background: Systematic assessment of severe asthma can be used to confirm the diagnosis, identify comorbidities, and address adherence to therapy. However, the prospective usefulness of this approach is yet to be established. The objective of this study was to determine whether the systematic assessment of severe asthma is associated with improved quality of life (QoL) and health-care use and, using prospective data collection, to compare relevant outcomes in patients referred with severe asthma to specialist centers across the United Kingdom. Methods: Data from the National Registry for dedicated UK Difficult Asthma Services were used to compare patient demographics, disease characteristics, and health-care use between initial assessment and a median follow-up of 286 days. Results: The study population consisted of 346 patients with severe asthma. At follow-up, there were significant reductions in health-care use in terms of primary care or ED visits (66.4% vs 87.8%, P < .0001) and hospital admissions (38% vs 48%, P = .0004). Although no difference was noted in terms of those requiring maintenance oral corticosteroids, there was a reduction in steroid dose (10 mg [8-20 mg] vs 15 mg [10-20 mg], P = .003), and fewer subjects required short-burst steroids (77.4% vs 90.8%, P = .01). Significant improvements were seen in QoL and control using the Asthma Quality of Life Questionnaire and the Asthma Control Questionnaire. Conclusions: To our knowledge, this is the first time that a prospective study has shown that a systematic assessment at a dedicated severe asthma center is associated with improved QoL and asthma control and a reduction in health-care use and oral steroid burden.

Introduction: While it is recommended that mental health professionals engage in family focused practice (FFP), there is limited understanding regarding psychiatric nurses’ practice with parents who have mental illness, their children and families in adult mental health services.
Methods: This study utilized a mixed methods approach to measure the extent of psychiatric nurses’ family focused practice and factors that predicted it. It also sought to explore the nature and scope of high scoring psychiatric nurses’ FFP and factors that affected their capacity to engage in FFP. Three hundred and forty three psychiatric nurses in 12 mental health services throughout Ireland completed the Family Focused Mental Health Practice Questionnaire (FFMHPQ). Fourteen nurses who achieved high scores on the FFMHPQ also participated in semi-structured interviews.
Results: Whilst the majority of nurses were not family focused a substantial minority were. High scoring nurses’ practice was complex and multifaceted, comprising various family focused activities, principles and processes. Nurses’ capacity to engage in FFP was determined by their knowledge and skills, working in community settings and own parenting experience.
Conclusions: Generally, low levels of family focused practice suggest the need for organizations to develop and implement guidelines, policies and training to support mental health professionals to adopt a whole family approach.

Background: Contact with primary care and psychiatric services prior to suicide may be considerable, presenting
opportunities for intervention. However, there is scant knowledge on the frequency, nature and determinants of
contact.
Method: Retrospective cohort study-an analysis of deaths recorded as suicide by the Northern Ireland Coroner’s
Office linked with data from General Practice patient records over a 2 year period
Results: Eighty-seven per cent of suicides were in contact with General Practice services in the 12 months before
suicide. The frequency of contact with services was considerable, particularly among patients with a common
mental disorder or substance misuse problems. A diagnosis of psychiatric problems was absent in 40 % of suicides.
Excluding suicide attempts, the main predictors of a noted general practitioner concern for patient suicidality are
male gender, frequency of consultations, diagnosis of mental illness and substance misuse.
Conclusions: Despite widespread and frequent contact, a substantial proportion of suicidal people were
undiagnosed and untreated for mental health problems. General Practitioner alertness to suicidality may be too
narrowly focused.
