Patients' Perceptions of Trichiasis Surgery: Results from the Partnership for Rapid Elimination of Trachoma (PRET) Surgery Clinical Trial

Trachoma

Trachoma is a neglected tropical disease caused by infection with conjunctival strains of Chlamydia trachomatis. It can result in blindness. Pathophysiologically, trachoma is a disease complex composed of two linked chronic processes: a recurrent, generally subclinical infectious-inflammatory disease that mostly affects children, and a non-communicable, cicatricial and, owing to trichiasis, eventually blinding disease that supervenes in some individuals later in life. At least 150 infection episodes over an individual's lifetime are needed to precipitate trichiasis; thus, opportunity exists for a just global health system to intervene to prevent trachomatous blindness. Trachoma is found at highest prevalence in the poorest communities of low-income countries, particularly in sub-Saharan Africa; in June 2021, 1.8 million people worldwide were going blind from the disease. Blindness attributable to trachoma can appear in communities many years after conjunctival C. trachomatis transmission has waned or ceased; therefore, the two linked disease processes require distinct clinical and public health responses. Surgery is offered to individuals with trichiasis and antibiotic mass drug administration and interventions to stimulate facial cleanliness and environmental improvement are designed to reduce infection prevalence and transmission. Together, these interventions comprise the SAFE strategy, which is achieving considerable success. Although much work remains, a continuing public health problem from trachoma in the year 2030 will be difficult for the world to excuse.

Characteristics and perspectives of patients with postoperative trichiasis in Hadiya Zone, Ethiopia

Background

Postoperative trachomatous trichiasis (PTT) is a challenge for trichiasis surgery programs. Little is known about PTT patients’ perceptions regarding outcomes and future disease management. This study aimed to understand the characteristics of PTT patients, how they managed trichiasis and their perceptions of prior surgeries and future surgery uptake.

Methods

Patients with PTT were identified during an existing trichiasis screening program in Hadiya Zone, Ethiopia. A vision assessment and evaluation of the eyelids were conducted to determine distance vision, presence and severity of trichiasis and eyelid contour abnormalities. A questionnaire was administered to obtain information regarding patients’ perceptions of surgery and PTT management approaches. Descriptive statistics were used to characterize PTT and determine associations between PTT severity and patient perceptions.

Results

Among 404 participants, most were female (79.7%) and aged 40–60 y (62.6%). In total, 514 eyelids had PTT, and nearly half had severe PTT (46.9%). Although >50% of participants were currently epilating to manage their PTT, the majority (82.8%) indicated that they wanted repeat surgery. Most participants indicated that pain persisted despite epilation. The majority (75.1%) indicated satisfaction with their prior surgery and 59.6% indicated that they would recommend surgery to others.

Conclusions

This study, which included a large proportion of severe PTT cases, indicated that individuals were generally satisfied with prior surgery and would prefer to have surgery again for PTT management.

Why do patients refuse trichiasis surgery? Lessons and an education initiative from Mtwara Region, Tanzania

BACKGROUND

Trachomatous trichiasis is one of the leading causes of preventable blindness worldwide. A relatively simple surgery can spare vision. Although this surgery is usually performed free of charge in endemic regions, multiple studies indicate that surgical refusal is common. Prior studies have attempted to examine these reasons, although they generally rely on patient recall months to years after the surgery was offered. This study set out to determine major decision-making factors at the time of refusal. In addition, this study looked for ways to help increase surgical uptake by targeting modifiable factors.

METHODOLOGY/PRINCIPAL FINDINGS

We used a combination of focus groups, interviews with community health workers, and individual interviews with trichiasis patients who refused surgery to understand their decision-making. We found that several factors influenced surgical refusals, including misconception regarding recovery time, inability to find a post-surgical caregiver, and the time of year of the surgical campaign. Fear of the surgery itself played a minimal role in refusals.

CONCLUSIONS/SIGNIFICANCE

Trichiasis patients refuse surgery for many reasons, but a large percentage is due to lack of information and education, and is, therefore, modifiable within the structure of a surgical outreach project. To address this, we developed a "frequently asked questions" (FAQ) document aimed at community health workers, which may have helped to decrease some of the misconceptions that had led to prior refusals.

Identifying Patient Perceived Barriers to Trichiasis Surgery in Kongwa District, Tanzania

BACKGROUND

Trachomatous trichiasis (TT), inturned eyelashes from repeated infection with Chlamydia trachomatis, is the leading infectious cause of blindness in the world. Though surgery will correct entropion caused by trachoma, uptake of TT surgery remains low. In this case-control study, we identify barriers that prevent TT patients from receiving sight-saving surgery.

METHODOLOGY/PRINCIPAL FINDINGS

Participants were selected from a database of TT cases who did (acceptors) and did not (non-acceptors) have surgery as of August 2015. We developed an in-home interview questionnaire, using open and closed-ended questions on perceived barriers to accessing surgical services. We compared responses between the acceptors and non-acceptors, examining differences in reasons for and against surgery, sources of TT information, and suggestions for improving surgical delivery. 167 participants (mean age 61 years, 79.7% females) were interviewed. Compared to acceptors, non-acceptors were more likely to report they had no one to accompany them to surgery (75.3% vs. 42.6%, p<0.0001), they could manage TT on their own (69.9% vs. 31.5%, p<0.0001), and the surgery camp was too far (53.4% vs. 28.7%, p = 0.001). Over 90% of both acceptors and non-acceptors agreed on the benefits of having surgery. Fear of surgery was the biggest barrier stated by both groups. Despite this fear, acceptors were more likely than non-acceptors to also report fear of losing further vision without surgery.

CONCLUSIONS/SIGNIFICANCE

Barriers included access issues, familial and/or work responsibilities, the perception that self-management was sufficient, and lack of education about surgery. Fear of surgery was the biggest barrier facing both acceptors and non-acceptors. Increasing uptake will require addressing how surgery is presented to community residents, including outlining treatment logistics, surgical outcomes, and stressing the risk of vision loss.
