Increasing healthcare costs: can we influence the costs of glaucoma care?

PURPOSE OF REVIEW Despite a decrease in real average growth rates per capita since 2009, healthcare costs continue to rise worldwide. Numerous patient-related and doctor-related factors have contributed to this rise. Glaucoma is the leading cause of irreversible blindness and requires chronic, usually lifelong treatment. As with other chronic diseases, the adherence to prescribed treatment is often low and maybe influenced by the cost of the therapy. The purpose of this review is to seek potential solutions to best control the escalating costs of glaucoma care. RECENT FINDINGS The studies we selected for this review can be divided into four different categories: costs of diagnostic tests; costs of direct comparisons between drugs or laser and conventional surgery; patient-related factors (such as adherence); and general aspects regarding costs: theoretical models and calculations. SUMMARY It is challenging to find reliable studies concerning this subject matter. As patients are under the umbrellas of variously organized healthcare systems which span different cultures, the costs between countries are difficult to compare. However, one common aspect to lower costs in glaucoma care is to improve patient adherence. Theoretical models with actual patient studies could enable cost reductions by comparing multiple diagnostic and therapeutic scenarios. VIDEO ABSTRACT: http://links.lww.com/COOP/A22

Influence of Cost of Care and Adherence in Glaucoma Management: An Update

The costs for glaucoma care are rising worldwide. The main reason is the increase of life expectancy and the increasing variety of diagnostic tests and therapeutically options by implants and devices. How can we influence the increase in costs? Does a relationship exist between the rising costs and the behavior of patients especially in regard to adherence of patients to the prescribed therapy? Are there ways to improve adherence? The costs of a disease can be estimated by adding the direct costs and the indirect costs deriving from the disease. Many studies have been looking at the direct costs, for example, the costs of diagnostic tests and treatment modalities. Unfortunately, not many studies investigated the indirect costs, i.e., costs related to the need of a person to accompany the patient during his or her outpatient visits or the costs deriving from loss of work capacity because of the disease itself or the outpatient visits. Adherence or the synonym compliance has been discussed since many years, and it seems that it remains a major problem in the management of many chronic diseases. Despite all efforts to improve adherence, the adherence rate in chronic diseases such as glaucoma or arterial hypertension remains considerably low. One of the main factors in improving adherence is raising patient's awareness of the disease by providing general understanding of their disease. Other important factors are simplified therapeutic regimens, e.g., fixed combination drops, sustained drug release techniques, or new glaucoma surgical procedures with a more favorable risk profile

Is laser trabeculoplasty the new star in glaucoma treatment?

PURPOSE OF REVIEW For decades, laser trabeculoplasty has been a well-proven therapeutic option in glaucoma management, and more recently, it has only gained in popularity. One reason for such popularity is that selective laser trabeculoplasty (SLT) is a therapy independent of patient adherence, which is typically low among glaucoma patients. Consequently, the number of studies on SLT has multiplied throughout the past years. This review provides an overview of studies on SLT from the last 12 months. RECENT FINDINGS The studies on treatment outcome show a wide range of success rates of SLT reaching between 18 and 88%; however, study designs differ and many studies are not directly comparable. The prospective laser trabeculoplasty for open-angle glaucoma and ocular hypertension (LiGHT) trial has demonstrated good efficacy of SLT - 75% of the eyes achieved their target pressure without drops and 58% after a single SLT. SUMMARY SLT has proven to be effective in lowering IOP with satisfactory success rates even after single SLT. SLT is repeatable independent of patient's adherence

Struktur/Funktion/Behandlung beim Glaukom: Fortschritt in den letzten 10 Jahren

Seit den 1990er-Jahren wurde mehrere sog. Landmark-Studien durchgeführt, die durch ihren multizentrischen, randomisierten und maskierten Aufbau eine wichtige Funktion in der Betreuung von Glaukompatienten haben. Im Bereich von Struktur/Funktion und der konservativen Glaukomtherapie sind insbesondere die Ocular Hypertension Treatment Study (OHTS) und die Collaborative Initial Glaucoma Treatment Study (CIGTS) mit ihren Folgestudien zu erwähnen. Die Ocular Hypertension Treatment Study (OHTS) untersuchte, ob eine IOD(Augeninnendruck)-senkende Therapie den Übergang einer okulären Hypertension in ein primäres Offenwinkelglaukom (POWG) beeinflusst und welche Risikofaktoren daran beteiligt sind. Bei der CIGTS wurde der Verlauf der Erkrankung bei einer medikamentösen vs. einer operativen Glaukomtherapie untersucht. In den neueren Studien United Kingdom Glaucoma Treatment Study (UKGTS) und Glaucoma Automated Test Evaluation (GATE) wurden der Einfluss der Therapie mit Latanoprost auf die Entstehung von Gesichtsfelddefekten (UKGTS) respektive verschiedene Methoden zum Glaukomscreening (GATE) untersucht. Die OHTS lieferte ein Ergebnis, das sowohl die prophylaktische Therapie als auch ein „watchful waiting“ rechtfertigt. Die CIGTS zeigte, dass unter Umständen auch eine chirurgische Therapie eines neu entdeckten Glaukoms bei moderaten bis fortgeschrittenen Glaukomen empfohlen werden kann. Eine Behandlung mit Latanoprost (UKTGS) reduzierte sowohl den Augendruck als auch die Progression von Gesichtsfeldern bei beginnendem und moderatem Glaukomschaden. Die GATE-Studie konnte keinen eindeutigen Vorteil einer Screeninguntersuchung – bei Kosteneffektivität und ohne dass ein substanzieller Anteil von Diagnosen verpasst wird – zeigen. = Since the 1990s several so-called landmark studies were carried out, which played an important role in the management of glaucoma patients due to their multicenter, randomized and masked structure. The Ocular Hypertension Treatment Study (OHTS) and the Collaborative Initial Treatment Glaucoma Study (CIGTS) and their follow-up studies are especially important in the conservative glaucoma management and in the evaluation of structure and function. The OHTS examined if lowering of the intraocular pressure (IOP) treatment reduces the progression from ocular hypertension to primary open angle glaucoma and what risk factors influence the progression. The CIGTS examined the progression of glaucoma in patients treated either with pharmacotherapy or with surgery. The recent studies, the United Kingdom Glaucoma Treatment Study (UKGTS) and Glaucoma Automated Test Evaluation (GATE) investigated the influence of treatment with latanoprost on the development of visual field defects and examination of different screening tests in glaucoma, respectively. The OHTS provided results that justify prophylactic treatment as well as watchful waiting. The results of CIGTS showed that under certain conditions surgical treatment of a newly discovered glaucoma can be recommended for moderate to advanced glaucoma. In the UKGTS treatment with latanoprost reduced the intraocular pressure and also the progression of visual field defects in beginning and moderate glaucoma damage. The GATE study found no clear-cut advantage of screening examinations, with cost effectiveness and without a substantial proportion of diagnoses being missed

Twenty-four hour intraocular pressure measurements and home tonometry

PURPOSE OF REVIEW IOP is the only treatable risk factor contributing to glaucoma and most management and treatment of glaucoma is based on IOP. However, current IOP measurements are limited to office hours and control of glaucoma in many patients would benefit from the ability to monitor IOP diurnally so as not to miss abnormal pressures, which occur outside of office hours Consequently, to improve patient care, the ability to enable accurate and minimally disruptive diurnal IOP monitoring would improve caring for these patients. RECENT FINDINGS The studies we selected for this review can be divided into three categories: self-/home-tonometry, continuous invasive intraocular pressure measurements, and continuous noninvasive ocular measurements. SUMMARY The desire to obtain better insight in our patients' true diurnal IOP has led to the development of home-tonometers, in addition to extraocular and intraocular continuous pressure measurement devices. All of the devices have respective advantages and disadvantages, but none to date completely fulfills the goal of providing a true diurnal IOP profile.Video abstracthttp://links.lww.com/COOP/A27

Influence of new treatment modalities on adherence in glaucoma

PURPOSE OF REVIEW It is well known that glaucoma patients are not adherent to their therapeutic regimens. The issue of nonadherence is multifactorial and includes inadequate communication between doctors and patients, resulting in significant costs associated with enhanced disease progression. Therapeutic regimens are risk factors which often influences adherence rates. Thus, alternative treatment modalities, especially those risk factors that do not rely on patients' cooperation, may enable improvements in long-term outcomes of glaucoma in patient. RECENT FINDINGS The studies selected for this review were divided into new medications, especially advancements in pharmaceutical approaches to treat glaucoma and new ways of delivering the medication, new surgical methods, especially minimally invasive surgery methods for glaucoma, and new studies about adherence in glaucoma. SUMMARY Surprisingly, a very few studies on glaucoma medication or surgery addressed the concept of adherence. However, adherence is discussed in studies which consider psychological aspects of patients or communication issues between doctors and patients. Although these studies were performed in clinical settings, the issue of adherence is not addressed; despite it has significant effect on long-term outpatient care. A combination of both aspects, adherence and miscommunication, should be considered in studies

We would like to thank Dr Ayla Basasoro Garmendia for the initial analyses of phase I survey answers.BACKGROUND/AIMS: The goal of health research is to improve patients care and outcomes. Thus, it is essential that research addresses questions that are important to patients and clinicians. The aim of this study was to develop a list of priorities for glaucoma research involving stakeholders from different countries in Europe. METHODS: We used a three-phase method, including a two-round electronic Delphi survey and a workshop. The clinician and patient electronic surveys were conducted in parallel and independently. For phase I, the survey was distributed to patients from 27 European countries in 6 different languages, and to European Glaucoma Society members, ophthalmologists with expertise in glaucoma care, asking to name up to five research priorities. During phase II, participants were asked to rank the questions identified in phase I using a Likert scale. Phase III was a 1 day workshop with patients and clinicians. The purpose was to make decisions about the 10 most important research priorities using the top 20 priorities identified by patients and clinicians. RESULTS: In phase I, 308 patients and 150 clinicians were involved. In phase II, the highest-ranking priority for both patients and clinicians was 'treatments to restore vision'. In phase III, eight patients and four clinicians were involved. The top three priorities were 'treatments to stop sight loss', 'treatments to restore vision' and 'improved detection of worsening glaucoma'. CONCLUSION: We have developed a list of priorities for glaucoma research involving clinicians and patients from different European countries that will help guide research efforts and investment
