BackgroundCancer not only impairs a patient’s physical and psychosocial functional behaviour, but also contributes to negative impact on family members’ health related quality of life. Currently, there is an absence of a relevant tool in Thai with which to measure such impact. The aim of this study was to translate and validate the Family Reported Outcome Measure (FROM-16) in Thai cancer patients’ family members.MethodsThai version of FROM-16 was generated by interactive forward-backward translation process following standard guidelines. This was tested for psychometric properties including reliability and validity, namely content validity, concurrent validity, known group validity, internal consistency, exploratory and confirmatory factor analysis. Construct validity was examined by comparing the Thai FROM-16 version with the WHOQOL-BREF-THAI.ResultsThe internal consistency reliability was strong (Cronbach’s alpha = 0.86). A Negative moderate correlation between the Thai FROM-16 and WHOQOL-BREF-THAI was observed (r = − 0.4545, p < 0.00), and known group validity was proved by a statistically significant higher score in family members with high burden of care and insufficient income. The factor analysis supported both 3-factor and 2-factor loading model with slight difference when compared with the original version.ConclusionsThe Thai FROM-16 showed good reliability and validity in Thai family members of patients with cancer. A slight difference in factor analysis results compared to the original version could be due to cross-culture application.
Introduction This describes variations in facility peritoneal dialysis (PD) effluent (PDE) culture techniques and local microbiology laboratory practices, competencies, and quality assurance associated with peritonitis, with a specific emphasis on factors associated with culture-negative peritonitis (CNP). Methods Peritonitis data were prospectively collected from 22 Thai PD centers between May 2016 and October 2017 as part of the Peritoneal Dialysis Outcomes and Practice Patterns Study. The first cloudy PD bags from PD participants with suspected peritonitis were sent to local and central laboratories for comparison of pathogen identification. The associations between these characteristics and CNP were evaluated. Results CNP was significantly more frequent in local laboratories (38%) compared with paired PDE samples sent to the central laboratory (12%, P < 0.05). Marked variations were observed in PD center practices, particularly with respect to specimen collection and processing, which often deviated from International Society for Peritoneal Dialysis Guideline recommendations, and laboratory capacities, capabilities, and certification. Lower rates of CNP were associated with PD nurse specimen collection, centrifugation of PDE, immediate transfer of samples to the laboratory, larger hospital size, larger PD unit size, availability of an on-site nephrologist, higher laboratory capacity, and laboratory ability to perform aerobic cultures, undertake standard operating procedures in antimicrobial susceptibilities, and obtain local accreditation. Conclusion There were large variations in PD center and laboratory capacities, capabilities, and practices, which in turn were associated with the likelihood of culturing and correctly identifying organisms responsible for causing PD-associated peritonitis. Deviations in practice from International Society for Peritoneal Dialysis guideline recommendations were associated with higher CNP rates.
Background Little is known about the prevalence of functional impairment in peritoneal dialysis (PD) patients, its variation by country, and its association with mortality or transfer to hemodialysis. Methods A prospective cohort study was conducted in PD patients from 7 countries in the Peritoneal Dialysis Outcomes and Practice Patterns Study (PDOPPS) (2014 – 2017). Functional status (FS) was assessed by combining self-reports of 8 instrumental and 5 basic activities of daily living, using the Lawton-Brody and the Katz questionnaires. Summary FS scores, ranging from 1.25 (most dependent) to 13 (independent), were based on the patient's ability to perform each activity with or without assistance. Logistic regression was used to estimate the odds ratio (OR; 95% confidence interval [CI]) of a FS score < 11 comparing each country with the United States (US). Cox regression was used to estimate the hazard ratio (HR; 95% CI) for the effect of a low FS score on mortality and transfer to hemodialysis, adjusting for case mix. Results Of 2,593 patients with complete data on FS, 48% were fully independent (FS = 13), 32% had a FS score 11 to < 13, 14% had a FS score 8 to < 11, and 6% had a FS score < 8. Relative to the US, low FS scores (< 11; more dependent) were more frequent in Thailand (OR = 10.48, 5.90 – 18.60) and the United Kingdom (UK) (OR = 3.29, 1.77 – 6.08), but similar in other PDOPPS countries. The FS score was inversely and monotonically associated with mortality but not with transfer to hemodialysis; the HR, comparing a FS score < 8 vs 13, was 4.01 (2.44 – 6.61) for mortality and 0.91 (0.58 – 1.43) for transfer to hemodialysis. Conclusion Regional differences in FS scores observed across PDOPPS countries may have been partly due to differences in regional patient selection for PD. Functional impairment was associated with mortality but not with permanent transfer to hemodialysis.
Background: Although caregivers allow peritoneal dialysis (PD) patients with disabilities the opportunity to perform PD, it is crucial to clarify the safety and effectiveness of assisted PD performed by caregivers compared to self-PD. Methods: PD patients from 22 PD centres in Thailand were prospectively followed in the Peritoneal Dialysis Outcomes and Practice Patterns Study during 2016–2017. Patients receiving assisted PD performed by caregivers were matched 1:1 with self-PD patients using propensity scores calculated by logistic regression. The associations between assisted PD and risk of mortality, peritonitis and permanent transfer to haemodialysis (HD) were assessed by multivariable competing risk regression. Results: Of 778 eligible patients, 447 (57%) required assisted PD performed by caregivers. Most of the caregivers were family members (98%), while the rest were non-family paid caregivers (2%). Patient factors associated with assisted PD were older age, female gender, lower educational level, cardiovascular comorbidities, diabetes, automated PD modality, poorer functional status and lower blood chemistries (albumin, creatinine, sodium, potassium and phosphate). After 1:1 matching, the baseline characteristics were adequately matched, and 269 patients in each group were analysed. Compared with self-PD, assisted PD was significantly associated with an increased risk of all-cause mortality (adjusted sub-hazard ratio: 2.15, 95% confidence interval: 1.24–3.74). There were no differences in the occurrences of peritonitis and permanent HD transfer between the groups. Conclusions: Assisted PD was required by more than half of Thai PD patients and was independently associated with a higher mortality risk. This may reflect causal effect or confounding by indication.
