Community implementation of the 3 Wishes Project: an observational study of a compassionate end-of-life care initiative for critically ill patients.

BACKGROUND: The 3 Wishes Project (3WP) promotes a personalized dying experience by eliciting and facilitating individualized terminal wishes for patients, families and the clinicians caring for them. We aimed to evaluate the adaptability of the 3WP to a community intensive care unit (ICU), and to describe the patients cared for with this palliative approach, as well as local implementation strategies. METHODS: The 3WP was implemented in a 15-bed community hospital ICU in southern Ontario from 2017 to 2019. In this observational, descriptive study, we invited adult patients (≥ 18 yr) whose risk of death was deemed to be 95% or greater by the attending physician, or patients undergoing withdrawal of life-support to participate. We abstracted patient data from medical records, as well as the type, timing and cost of each wish, which person or service made and facilitated each wish, and if and why wishes were completed or not. We summarized data both narratively and quantitatively. RESULTS: The 3WP helped to realize 479 (99.2%) of 483 terminal wishes for 101 dying patients. This initiative was introduced as an interprofessional intervention and championed by nursing staff who were responsible for most patient enrolment and wish facilitation. Wishes included humanizing the ICU environment for the patient with belongings and blankets, musical performances, smudging and bathing ceremonies, and keepsakes. The cost was $5.39 per patient (standard deviation $22.40), with 430 (89.8%) wishes incurring no cost. Wishes made directly by patients accounted for 30 (6.2%) of wishes; those from family members and ICU staff accounted for 236 (48.9%) and 238 (49.3%) of wishes, respectively. The program comforted patients and their loved ones, motivating clinicians to sustain this end-of-life intervention. INTERPRETATION: We documented successful implementation of the 3WP in a community hospital, showing program adaptability and uptake outside of academic centres at relatively low cost. The lack of strict protocolization and personalized design of this intervention underscores its inherent flexibility, with potential to promote individualized end-of-life care in nonacademic hospital wards, homes or hospice.

The Antioxidants in Prevention of Cataracts Study: effects of antioxidant supplements on cataract progression in South India.

AIM: To determine if antioxidant supplements (beta carotene and vitamins C and E) can decrease the progression of cataract in rural South India. METHODS: The Antioxidants in Prevention of Cataracts (APC) Study was a 5 year, randomised, triple masked, placebo controlled, field based clinical trial to assess the ability of interventional antioxidant supplements to slow cataract progression. The primary outcome variable was change in nuclear opalescence over time. Secondary outcome variables were cortical and posterior subcapsular opacities and nuclear colour changes; best corrected visual acuity change; myopic shift; and failure of treatment. Annual examinations were performed for each subject by three examiners, in a masked fashion. Multivariate modelling using a general estimating equation was used for analysis of results, correcting for multiple measurements over time. RESULTS: Initial enrolment was 798 subjects. Treatment groups were comparable at baseline. There was high compliance with follow up and study medications. There was progression in cataracts. There was no significant difference between placebo and active treatment groups for either the primary or secondary outcome variables. CONCLUSION: Antioxidant supplementation with beta carotene, vitamins C and E did not affect cataract progression in a population with a high prevalence of cataract whose diet is generally deficient in antioxidants.

Blindness in the Indian state of Andhra Pradesh.

PURPOSE: To determine the current prevalence and causes of blindness in the Indian state of Andhra Pradesh to assess if blindness has decreased since the last survey of 1986-1989. METHODS: A population-based epidemiology study, using a stratified, random, cluster, systematic sampling strategy, was conducted in the state of Andhra Pradesh in India. Participants of all ages (n = 10,293), 87.3% of the 11,786 eligible, from 94 clusters in one urban and three rural areas representative of the population of Andhra Pradesh, underwent interview and a detailed dilated ocular evaluation by trained professionals. Blindness was defined as presenting distance visual acuity < 6/60 or central visual field < 20(o) in the better eye. RESULTS: Two hundred seventy-five participants were blind, a prevalence of 1.84% (95% confidence interval, 1.49%-2.19%) when adjusted for the age, sex, and urban-rural distribution of the population in 2000. The causes of this blindness were easily treatable in 60.3% (cataract, 44%; refractive error, 16.3%). Preventable corneal disease, glaucoma, complications of cataract surgery, and amblyopia caused another 19% of the blindness. Blindness was more likely with increasing age and decreasing socioeconomic status, and in female subjects and in rural areas. Among the 76 million population of Andhra Pradesh, 714,400 are estimated to have cataract-related blindness (615,600 cataract, 53,200 cataract surgery-related complications, 45,600 aphakia), and 228,000 refractive error-related blindness (159,600 myopia, 22,800 hyperopia, 45,600 refractive error-related amblyopia). If 95% of the cataract and refractive error blindness in Andhra Pradesh had been treated effectively, 3.4 and 7.4 million blind-person-years, respectively, could have been prevented. If 90% of the blindness due to preventable corneal disease and glaucoma had been prevented, another 2.7 million blind-person-years could have been prevented. CONCLUSIONS: The prevalence of blindness in this Indian state has increased from 1.5% in the late 1980s to 1.84% currently, as against the target of the National Program for Control of Blindness to reduce the prevalence to 0.3% by 2000. The number of people with cataract-related blindness has not reduced even with the eye care policy focus on cataract. Reduction of blindness in India will require strategies that are more effective than those that have been pursued so far.

Population based assessment of uveitis in an urban population in southern India.

AIM: To assess the prevalence of active and inactive uveitis unrelated to previous surgery or trauma in an urban population in southern India. METHODS: As part of the Andhra Pradesh Eye Disease Study, 2522 subjects (85.4% of those eligible), a sample representative of the population of Hyderabad city in southern India, underwent interview and detailed dilated eye examination. Presence of sequelae of uveitis without current active inflammation was defined as inactive uveitis. RESULTS: Unequivocal evidence of active or inactive uveitis unrelated to previous surgery or trauma was present in 21 subjects, an age-sex adjusted prevalence of 0.73% (95% confidence interval (CI) 0.44-1.14%). Active uveitis was present in eight subjects, an age-sex adjusted prevalence of 0.37% (95% CI 0. 19-0.70), of which 0.06% was anterior, 0.25% intermediate, and 0.06% posterior. The 0.36% (95% CI 0.17-0.68%) prevalence of inactive uveitis included macular chorioretinitis scars (0.26%), anterior (0. 07%) and previous vasculitis involving the whole eye (0.03%). The prevalence of visual impairment due to uveitis of less than 6/18 in at least one eye was 0.27%, less than 6/60 in at least one eye was 0. 16%, and less than 6/60 in both eyes was 0.03%. CONCLUSION: These population based cross sectional data give an estimate of the prevalence of various types of uveitis in this urban population in India. Active or past uveitis that might need treatment at some stage was present in one of every 140 people in this population.

Sample size for ophthalmology studies.

Knowledge and the usage of actual sample size formulae are a necessity as validity of the inferences from research studies is often dependent on this. This paper explains how sample sizes are calculated. The concept of sampling variation is explained to emphasize the need for its proper calculation. Sample size formulae are explained with examples to provide researchers with a means of calculating the sample sizes for the commonly used study designs. Ophthalmic data are used as examples. It is perceived that this will improve the quality of inferences drawn from ophthalmic research studies.

HIV and HTLV-I infections in the Americas: a regional perspective.

With over 143,000 cases of AIDS reported to the World Health Organization from 145 countries and with an estimated 5 to 10 million people worldwide infected with HIV, AIDS has become firmly established as a global pandemic. In the region of the Americas over 100,862 cases of AIDS have been reported with indigenous transmission documented in 45 to 46 countries. While North America has the highest annual number of AIDS cases per population, with 72 cases/million, the Caribbean subregion has a disproportionately high number of cases, with annual rates as high as 200 to 300 cases/million population for some countries. Despite differences in absolute number of cases, there has been a remarkable similarity in the temporal rate of increase of AIDS in the countries of the Americas, reflecting delayed introduction of the virus to some areas with an early exponential increase similar to that observed initially in the United States. Although the modes of transmission of HIV are the same throughout the region, evidence of increasing bisexual and heterosexual transmission, particularly in the Caribbean subregion, has resulted in a lower male-to-female ratio of AIDS cases and increased perinatal transmission. Clinically, a resurgence of diarrheal diseases, respiratory infections, and tuberculosis has been documented in association with HIV infection in many tropical countries of the Americas. With relatively high rates of HTLV-I infection already established in the Caribbean subregion, the overall public health problems of the Americas will be markedly potentiated by further spread of these 2 human retroviruses. If HIV infection continues to penetrate the poor and less advantaged populations in Latin America and the Caribbean, the potential exists for a massive epidemic in the Americas that may rapidly parallel the situation in Africa.

PIP: The article describes in detail the extent and nature of HIV and HTLV-1 infections, and AIDS in the Americas. Surveillance statistics are provided for general populations, homosexual and bisexual men, IV-drug users, female prostitutes, hemophiliacs, heterosexual partners of HIV-infected persons, blood donors, and pregnant women. As of publication, over 100,862 AIDS cases have been reported in the region, with indigenous transmission documented in 45-46 countries. Clinical manifestations of HIV infection and AIDS are discussed. North America claims the highest annual AIDS cases per population at 72/million, while the Caribbean subregion has a disproportionately high number of cases, with annual rates reaching 200-300/million for some countries. The temporal rate of increase of AIDS cases has, however, been fundamentally comparable for all countries of the Americas. While HIV transmission modes are the same throughout the region, increasingly lower male-female ratios of AIDS cases, and more cases of perinatal transmission especially in Caribbean countries. Diarrheal disease, respiratory infections, and tuberculosis have also been documented as associated with HIV infection in many tropical countries of the Americas. Further, relatively high rates of HTLV-1 infection in the Caribbean will only exacerbate already significant public health problems faced by some countries of the region. Should HIV continue infiltrating poor, disadvantaged populations of Latin America and the Caribbean, HIV infection levels and AIDS could reach epidemic proportions similar to that witnesses in Africa.

Yaws in the Americas.

Until the middle of this century, yaws was a major public health problem in the Americas Region of the World Health Organization. All countries located between the tropics of Cancer and Capricorn reported cases of yaws. From 1950 to 1957, major programs for the eradication of yaws were implemented throughout the region, and yaws rapidly ceased to be a threat. As of 1983, sporadic cases continued to occur in limited geographic areas of Colombia, French Guyana, Guyana, and Suriname.

Frequency and distribution of salpingitis and pelvic inflammatory disease in short-stay hospitals in the United States.

Pelvic inflammatory disease is not a reportable condition in the United States. Based on data extracted from the Hospital Discharge Survey conducted by the National Center for Health Statistics, this article presents estimates of the frequency and distribution of PID in short-stay hospitals from 1970 through 1975.

PIP: Estimates of the frequency and distribution of pelvic inflammatory disease (PID) in short-stay hospitals in the US as measured by the Hospital Discharge Survey (HDS) of the National Center for Health Statistics are presented. Annual estimates of International Classification of Diseases codes for acute salpingitis, chronic salpingitis, unspecified salpingitis and PID for 1970-75 were pooled and the results presented as mean annual numbers for the period. The probable errors of the estimates ranged from a low of +or- 2.3% to a high of +or- 30.0%, and depended on the magnitude of the estimate. Overall, there were 212,611 diagnoses of salpingitis and PID yearly, of which 146,115 were PID and 66,496 were salpingitis. Chronic salpingitis (23,555 cases) was diagnosed about twice as frequently as acute salpingitis (12,961 cases), but almost 1/2 of cases were not specified. When the diagnosis was acute salpingitis, it was the principal cause for admission in 81% of all cases, compared to a corresponding rate of 38% for chronic salpingitis. Diagnosed salpingitis was the principal cause for admission in 53% of cases, compared to 70% for PID. Overall the 2 conditions were the principal reasons for hospital admission in 65% of cases. The mean and median days of hospital stay for patients with salpingits or PID as the principal diagnosis were 6.6 and 6.2 days, respectively. The median age of women with a principal diagnosis of acute salpingitis was 23 years while for chronic salpingitis it was 29 years. The overall rate of hospitalization for salpingitis and PID was 199/100,000 population . For white women the rate of 154 and for all other races it was 509/100,000. In 204,596 cases in which marital status was known, the highest risk groups were separated and divorced women, with rates of 867.4 and 617.9 respectively. Among women, 10.3 of every 1000 hospital admissions, excluding those for pregnancy, were necessitated by salpingitis or PID. The group at highest risk was 20-24 years of age, while the risk in women over 40 was quite low. Salpingitis and PID were the cause of 1 in every 11 hospital admissions in women aged 20-24 in races other than white. The overall frequency of hospital deaths among women with diagnoses of salpingitis or PID was 4.3/1000 hospitalized women. Surgery was performed on 42.3% of patients with principal diagnoses of salpingitis or PID and 76.1% of women with secondary diagnoses. 54.3% of the hospitalized women underwent operations, of whom 45.6%, or 52,634 women, underwent hysterectomies.
