Uptake of health monitoring and disease self-management in Australian adults with neurofibromatosis type 1: strategies to improve care

Characterization of health concerns in people with neurofibromatosis type 1

BACKGROUND

Neurofibromatosis 1 (NF1) is a common cancer predisposition syndrome. Affected individuals require lifelong surveillance and often suffer progressive disfigurement due to cutaneous neurofibromas. The aim of this research was to characterize health concerns and quality of life (QOL) in a population cohort.

METHODS

An online survey was completed by 68 adults and 32 parents of children with NF1, and 60 controls. The survey included the Skindex-29 QOL scale, 5D-itch scale, and additional health questions.

RESULTS

Frequency of itch was high in children (50%) and adults (69%), with most expressing interest in treatment for itch. The presence of itch and increased visibility of NF1 were predictors of poorer QoL. Many adults (53%) and parents (44%) desired access to treatment to improve cosmetic appearance. Muscle weakness/tiredness was also prevalent amongst (60-70%) adults and children with NF1. Two-thirds of adults with NF1 reported limited awareness of NF1 services and poor knowledge of surveillance, particularly breast screening in young women.

CONCLUSION

This study highlights the impact of NF1-related itch and visibility in adults and children with a need for cosmetic and itch treatment. The findings emphasize a need for strategies to promote awareness, and access to management and treatment of NF1 in adults.

Impact of neurofibromatosis type 1 in an adult community population

Background

Neurofibromatosis type 1 (NF1) is a common tumor predisposition syndrome with varying manifestations and severity. Adult NF1 patients often experience fragmented care, so we sought to characterize the health and demographic features of a community-based population of adults with NF1 and hypothesized that lack of a specialty clinic for adult NF1 patients correlates with unmet needs.

Methods

Retrospective case-control study of all adult cases of NF1 among 4.06 million medical records in a Pacific Northwest population. 122 case charts were reviewed to ascertain NF1 disease features, comorbidities, and severity of disease. A 1:1 control cohort was selected by matching case/control by age, sex, and ZIP code to compare demographic features and health status.

Results

Adult NF1 patients were less likely to have private insurance, be employed, and have children, but were equally likely to be married. One half of cases had disease features compromising health and well-being, and care involved 26 different specialties. Excluding neurofibromas, 43% of cases had cancer compared to 10% of controls [P < .0001, OR 5.38 (2.53-11.4)]. Only 27% of women ages 30-50 had undergone age-appropriate enhanced breast cancer surveillance. Behavioral health problems were found in 60% of NF1 patients compared to 37% of controls [P < .001, OR 2.61 (1.52-4.50)]. 93% of cases referred to a NF1 specialty center underwent a change in management upon establishing care.

Conclusions

NF1 patients may benefit from coordinated management of care in a specialty center.

The psychological impact and experience of breast cancer screening in young women with an increased risk of breast cancer due to neurofibromatosis type 1

Women with neurofibromatosis type 1 (NF1) have an increased risk of developing early breast cancer with a poorer prognosis compared to the general population. Therefore, international management guidelines recommend regular screening in women with NF1 starting from 30 to 35 years. As the psychological impacts of breast cancer screening in other high-risk populations cannot be extended to women with NF1, due to increased incidence of cognitive and mental health issues, the psychological harms of breast screening in women with NF1 are unknown. Consequently, the aim of this study was to assess the psychological impact of breast cancer screening in women with NF1 attending an established risk management clinic. Twenty-eight women with NF1 (30–50 years) completed psychological well-being and patient experience questionnaires, administered across five time points, before and after their initial and second round annual breast screening visits. Preliminary findings demonstrated the screening regimen was well-tolerated, with most participants reporting high satisfaction with the screening process. Overall, no significant increase in psychological distress related to the breast screening process was identified, with mean cancer worry and anxiety scores decreasing over time. However, some women did experience negative aspects of screening and barriers to re-attendance at annual breast screening appointments. As some women with NF1 exhibited clinical levels of psychological distress prior to screening, efforts to identify those at risk and additional support to address concerns and expectations throughout the breast screening process may be beneficial.

Factors associated with parental knowledge of neurofibromatosis type 1 (NF1): Parental affected status and genetic counseling

Neurofibromatosis type 1 (NF1) is a genetic condition characterized by various cutaneous, neurological and psychological manifestations. The present study examined whether parental knowledge of NF1 is associated with a parent's NF1 status, affected or unaffected, and exposure to genetic counseling. Parents of children with NF1 were invited to complete an online survey answering true or false and multiple-choice questions to evaluate their overall knowledge of NF1. The study included 274 respondents, of which NF1 knowledge scores were significantly higher for unaffected parents (p < .001), and for parents who reported previously meeting with a genetic counselor (p < .001). Items pertaining to NF1-related cancer were least likely to be answered correctly. The results of the current study revealed lower overall NF1 knowledge in affected parents and knowledge gaps identifying areas where focused NF1 education may be beneficial.

Patient coaching in specialist consultations. Which patients are interested in a coach and what communication barriers do they perceive?

OBJECTIVE

To characterize patients interested in support by a patient coach to guide them in medical specialist consultations.

METHODS

We compared 76 patients interested in a patient coach with 381 patients without such an interest, using a representative panel of patients with a chronic disease in the Netherlands. Independent variables were demographic factors, socio-economic status, perceived efficacy in patient-provider interaction, communication barriers, health literacy, (duration and type of) disease(s) and activation level.

RESULTS

In univariate analyses, patients who are interested in a coach were significantly older, had lower health literacy skills and less self-efficacy and, overall, experienced more communication barriers (>4), than patients without such interest (1-2 barriers). Multivariate analyses indicated three communications barriers as determinants of patient interest in a coach: feeling tense, uncertainty about own understanding, and believing that a certain topic is not part of a healthcare providers' task.

CONCLUSION

Patients interested in a coach perceive specific barriers in communicating with their medical specialist. In addition, patients who are > = 65 years, have lower health literacy and low self-efficacy may have interest in a coach.

PRACTICE IMPLICATIONS

Characterizing patients interested in a patient coach facilitates identification of those who could benefit from such a coach in clinical practice.

Increasing access to specialty care for rare diseases: a case study using a foundation sponsored clinic network for patients with neurofibromatosis 1, neurofibromatosis 2, and schwannomatosis

Background

Our primary aim was to assess the ability of a non-profit foundation-sponsored clinic network to facilitate access to specialized care for patients with neurofibromatoses (NF), a group of neurogenetic disorders including NF1, NF2, and schwannomatosis (SWN). Our secondary aim was to identify how our findings in NF could be applied more broadly to other rare diseases.

Methods

We retrospectively reviewed aggregate data on patient volume reported by specialty NF clinics in a nonprofit network from 2008 to 2015. We classified clinics as high or low volume for disease type (NF1 and NF2/schwannomatosis) and pediatric/adult care. We compared clinic-level data to self-reported patient-level data from a large online patient registry.

Results

Between 2008 and 2015, the number of certified NF clinics grew from 32 to 50, and annual patient volume rose from 6776 to 10,245 patients (13% of the total estimated U.S. NF patient population). For patient registry participants (n = 4476), the median driving distance to the nearest network clinic was 51.3 miles. Driving distances to reach high-volume centers were elevated for adults compared to children (295.8 vs. 67.9 miles), and schwannomatosis and NF2 patients compared to NF1 patients (310.9 vs. 368.1 vs. 161.7 miles). Of registry participants reporting their location of care (n = 2271), only 43.2% received care in a network specialty clinic, with especially low rates of attendance in the Southwest and Far West.

Conclusions

While the number of certified NF clinics and volume of patients seen in these clinics has increased, many NF patients still do not attend specialty clinics and/or travel a significant distance for care. Geographic access to care is more limited for adults, patients with rarer conditions, and patients in the Western U.S. Potential measures to improve access to specialty care for people living with NF and other rare diseases are discussed.
