Quantifying Regional and Health Care Variations to Identify Ways to Improve Hemodialysis Service Quality and Survival Outcomes

Jamal A, Babazono A, Li Y, Yoshida S, Fujita T, Kim SA

Am J Med Qual, 2021 5 20;36(5):345-354.
PMID: 34010165 DOI: 10.1097/01.JMQ.0000735484.44163.ce

The authors examined variations in hemodialysis care and quantified the effect of these variations on all-cause mortality. Insurance claims data from April 1, 2017 to March 30, 2018 were reviewed. In total, 2895 hospital patients were identified, among whom 398 died from various causes. Controlling effects of the facility and secondary medical care areas, all-cause mortality was associated with older age, heart failure, malignancy, cerebral stroke, severe comorbidity, and the first and ninth centile of physician density. Multilevel analyses indicated a significant variation at facility level (σ22 0.27, 95% confidence interval: 0.09-0.49). Inclusion of all covariates in the final model significantly reduced facility-level variance. Physician density emerged as an important factor affecting survival outcome; thus, a review of workforce and resource allocation policies is needed. Better clinical management and standardized work processes are necessary to attenuate differences in hospital practice patterns.

International Medical Journal Malaysia, 2017;16(1):45-52.
MyJurnal

Urine output provides a rapid estimate for kidney function, and its use has been incorporated in the diagnosis of acute kidney injury. However, not many studies had validated its use compared to the plasma creatinine. It has been showed that the ideal urine output threshold for prediction of death or the need for dialysis was 0.3 ml/kg/h. We aim to assess this threshold in our local ICU population.

Cardiovascular (CV) event is the most common cause of death in dialysis patients. Both traditional and nontraditional CV risk factors related to malnutrition, inflammation, and anemia are commonly found in this population. This study was conducted to evaluate the burden factors of CV risk factors and its management in our regularly dialyzed patients. It was a single-center, cross-sectional analysis of prevalent intermittent hemodialysis (IHD) and continuous ambulatory peritoneal dialysis (CAPD) patients followed up in our hospital. Both the traditional and non-traditional CV risk factors were recorded and compared between the two groups. Eighty-eight patients were recruited. Forty-five were treated with CAPD and 43 patients were treated with IHD. The mean age was 49.5 ± 15.17 years old and 54.5% were females. Eighty percent were Malay followed by Chinese (14.7%) and Indian (5.7%). Thirty-eight percent were hypertensive and 17% were diabetic. The mean age of CAPD patients was 48.9 ± 16.9 compared to 50 ± 13.5 years old for IHD patients (P > 0.05). The body mass index (BMI) of CAPD patients was 23.9 kg/m2 versus 21.7 kg/m2 of the IHD (P = 0.04). The systolic and diastolic blood pressure of CAPD patients were 158 and 89 mm Hg in comparison to 141 and 72 mm Hg in IHD patients (P <0.001) and their total and low-density lipoprotein cholesterol level were 5.93 mmol/L and 3.84 mmol/L versus 4.79 mmol/L and 2.52 mmol/L, respectively (P≤0.001). The CAPD patients were hyperglycemic more than IHD patients, although it was not statistically significant. All the nontraditional CV risk factors except serum albumin were comparable between the two groups. Serum albumin in CAPD patients was 35.5 g/L compared to 40.8 g/L in the IHD patients (P <0.001). In our prevalent dialysis-dependent patients, both traditional and non-traditional CV risk factors are common. Due to the prolonged and continuous glucose exposure from the peritoneal dialysis fluid, the CAPD patients had highly atherogenic serum, higher BMI, and intensified inflammation which pre-disposed them to higher CV events.

Benchmarking Diet Quality to Assess Nutritional Risk in Hemodialysis Patients: Applying Adequacy and Moderation Metrics of the Hemodialysis-Healthy Eating Index

Sualeheen A, Khor BH, Balasubramanian GV, Sahathevan S, Chinna K, Mat Daud ZA, et al.

J Ren Nutr, 2022 Nov;32(6):726-738.
PMID: 35182714 DOI: 10.1053/j.jrn.2022.02.002

OBJECTIVES: This study modified Healthy Eating Index (HEI) based on hemodialysis (HD)-specific nutritional guidelines and investigated associations between the diet quality (DQ) and nutritional risk in HD patients.
METHODS: The HD-HEI tool adapted the Malaysian Dietary Guidelines 2010 framework according to HD-specific nutrition guidelines. This HD-HEI was applied to 3-day dietary records of 382 HD patients. Relationships between HD-HEI scores and nutritional parameters were tested by partial correlations. Binary logistic regression models adjusted with confounders were used to determine adjusted odds ratio (adjOR) with 95% confidence interval (CI) for nutritional risk based on HD-HEI scores categorization.
RESULTS: The total HD-HEI score (51.3 ± 10.2) for this HD patient population was affected by ethnicity (Ptrend < .001) and sex (P = .003). No patient achieved "good" DQ (score: 81-100), while DQ of 54.5% patients were classified as "needs improvement" (score: 51-80) and remaining as "poor" (score: 0-51). Total HD-HEI scores were positively associated with dietary energy intake (DEI), dietary protein intake (DPI), dry weight, and handgrip strength, but inversely associated with Dietary Monotony Index (DMI) (all P

Factors Associated with Symptom Burden in Adults with Chronic Kidney Disease Undergoing Hemodialysis: A Prospective Study

Gunarathne TGNS, Tang LY, Lim SK, Nanayakkara N, Damayanthi HDWT, Abdullah KL

Int J Environ Res Public Health, 2022 May 03;19(9).
PMID: 35564935 DOI: 10.3390/ijerph19095540

People with end stage renal disease and undergoing hemodialysis experience a high symptom burden that impairs quality of life. This study aimed to assess the prevalence, dynamicity and determinants of symptom burden among middle-aged and older adult hemodialysis patients. A descriptive cross-sectional study together with a longitudinal assessment was used. A total of 118 and 102 hemodialysis patients were assessed at baseline and at a 6-month follow-up. Validated questionnaires were used to assess the symptom burden, stress, illness perception and social support. Multiple linear regression analysis was used to determine the factors associated with symptom burden. The median number of symptoms experienced was 21 (Interquartile Range (IQR); 18−23) and 19 (IQR; 13−22) at baseline and 6 months, respectively. Having elevated stress (β = 0.65, p ≤ 0.005) and illness perception (β = 0.21, p = 0.02) were significantly predicted symptom burden at baseline (F (4, 112) = 55.29, p < 0.005, R2 = 0.664). Stress (β = 0.28, p = 0.003), illness perception (β = 0.2, p = 0.03), poor social support (β = −0.22, p = 0.01) and low body weight (β = −0.19, p = 0.03) were the determinants for symptom burden at 6 months (F (5, 93) = 4.85, p ≤ 0.005, R2 = 0.24). Elevated stress, illness perception level, poor social support and low post-dialysis body weight were found to be determinants for symptom burden. Attention should be given to psychosocial factors of hemodialysis patients while conducting assessment and delivering care to patients.

Fulltext The effects of psychosocial and economic factors on the quality of life of patients with end-stage renal disease and their caregivers in Klang Valley, Malaysia: protocol for a mixed-methods study

Ibrahim N, Chu SY, Siau CS, Amit N, Ismail R, Abdul Gafor AH

BMJ Open, 2022 Jun 03;12(6):e059305.
PMID: 36691236 DOI: 10.1136/bmjopen-2021-059305

INTRODUCTION: The number of patients in Malaysia requiring dialysis is expected to rise substantially in the future due to the ageing population and increasing prevalence of diabetes mellitus and hypertension. Hence, more individuals will be expected to adopt the role of caregivers in the future. The upward trend of end-stage renal disease (ESRD) and caregiving for dialysis patients has detrimental consequences for both patients and caregivers in terms of their psychological well-being and quality of life. Despite the current circumstances, there are very few studies in Malaysia that have explored the psychosocial factors, specifically on the economic impact of the management of ESRD.
METHODS AND ANALYSIS: This two-phase sequential explanatory mixed-methods design, incorporating a quantitative design (phase I) and a qualitative study (phase II), is to be conducted in 4 government hospitals and 10 other non-governmental organisations or private dialysis centres within Klang Valley, Malaysia. A cross-sectional survey (phase I) will include 236 patient-caregiver dyads, while focus group discussions (phase II) will include 30 participants. The participants for both phases will be recruited purposively. Descriptive statistics, independent sample t-tests and multiple regression analysis will be used for analyses in phase I, and thematic analysis will be used in phase II.
ETHICS AND DISSEMINATION: Approval for the study has been obtained from the National Medical Research and Ethics Committee (MREC) (NMRR-21-1012-59714) and the Research Ethics Committee of Hospital Canselor Tuanku Muhriz UKM (UKM PPI/111/8/JEP-2021-078) and University of Malaya Medical Centre (MREC ID NO: 2 02 178-10346). Informed consent of the participants will be obtained beforehand, and no personal identifiers will be obtained from the participants to protect their anonymity. The findings will be published in peer-reviewed scientific journals and presented at national or international conferences with minimal anonymised data.

Atypical neuroleptic malignant syndrome and non-alcoholic Wernicke's encephalopathy

Hor ESL, Singh GP, Omar NA, Russell V

BMJ Case Rep, 2021 Aug 05;14(8).
PMID: 34353834 DOI: 10.1136/bcr-2021-244082

We report the case of a middle-aged woman with a history of bipolar disorder, in the absence of alcohol or substance misuse. The patient had been maintained on fluphenazine decanoate depot and now presented acutely with cognitive dysfunction and rigidity. Laboratory tests revealed elevated creatine kinase, acute kidney injury with metabolic acidosis and transaminitis, leading to a provisional diagnosis of neuroleptic malignant syndrome (NMS). Neuroleptics were withheld; dialysis was commenced; and blood biochemistry parameters improved in tandem. However, mental status changes persisted, and re-evaluation revealed multidirectional nystagmus with bilateral past-pointing. MRI confirmed the diagnosis of Wernicke's encephalopathy (WE). Prompt recovery followed treatment with high-dose intravenous thiamine. We discuss the co-occurrence of NMS and non-alcoholic WE-highlighting the need for a high index of suspicion for these relatively rare neuropsychiatric diagnoses which are often missed in those with atypical presentations.

Fulltext Preparation and characterization of a curcumin nanoemulsion gel for the effective treatment of mycoses

Al Fatease A, Alqahtani A, Khan BA, Mohamed JMM, Farhana SA

Sci Rep, 2023 Dec 20;13(1):22730.
PMID: 38123572 DOI: 10.1038/s41598-023-49328-2

Fungal infections of skin including mycoses are one of the most common infections in skin or skins. Mycosis is caused by dermatophytes, non-dermatophyte moulds and yeasts. Various studies show different drugs to treat mycoses, yet there is need to treat it with applied drugs delivery. This study was designed to prepare a bio curcumin (CMN) nanoemulsion (CMN-NEs) for transdermal administration to treat mycoses. The self-nanoemulsification approach was used to prepare a nanoemulsion (NE), utilizing an oil phase consisting of Cremophor EL 100 (Cre EL), glyceryl monooleate (GMO), and polyethylene glycol 5000 (PEG 5000). Particle size (PS), polydispersity index (PDI), zeta potential (ZP), Fourier transform infrared (FTIR) spectrophotometric analysis, and morphological analyses were performed to evaluate the nanoemulsion (NE). The in vitro permeation of CMN was investigated using a modified vertical diffusion cell with an activated dialysis membrane bag. Among all the formulations, a stable, spontaneously produced nanoemulsion was determined with 250 mg of CMN loaded with 10 g of the oil phase. The average droplet size, ZP, and PDI of CMN-NEs were 90.0 ± 2.1 nm, - 7.4 ± 0.4, and 0.171 ± 0.03 mV, respectively. The release kinetics of CMN differed from zero order with a Higuchi release profile as a result of nanoemulsification, which also significantly increased the flux of CMN permeating from the hydrophilic matrix gel. Overall, the prepared nanoemulsion system not only increased the permeability of CMN but also protected it against chemical deterioration. Both CMN-ME (24.0 ± 0.31 mm) and CMN-NE gel (29.6 ± 0.25 mm) had zones of inhibition against Candida albicans that were significantly larger than those of marketed Itrostred gel (21.5 ± 0.34 mm). The prepared CMN-NE improved the bioavailability, better skin penetration, and the CMN-NE gel enhanced the release of CMN from the gel matrix on mycotic patients.

Fulltext Poor Sleep Quality, Depression and Social Support Are Determinants of Serum Phosphate Level among Hemodialysis Patients in Malaysia

Ng ESY, Wong PY, Kamaruddin ATH, Lim CTS, Chan YM

Int J Environ Res Public Health, 2020 Jul 16;17(14).
PMID: 32708766 DOI: 10.3390/ijerph17145144

Despite optimal control of serum phosphate level being imperative to avoid undesirable health outcomes, hyperphosphataemia is a highly prevalent mineral abnormality among the dialysis population. This study aimed to determine factors associated with hyperphosphatemia among hemodialysis patients in Malaysia. Multiple linear regression analysis was used to ascertain the possible factors that influence serum phosphate levels. A total of 217 hemodialysis patients were recruited. Hyperphosphatemia was prevalent. Only approximately 25% of the patients were aware that optimal control of hyperphosphatemia requires the combined effort of phosphate binder medication therapy, dietary restriction, and dialysis prescription. The presence of diabetes mellitus may affect serum phosphate levels, complicating dietary phosphorus management. Patients who were less depressive portrayed higher serum phosphate levels, implying intentional non-compliance. Better compliance on phosphate binder, longer sleep duration, and higher social support was associated with a lower level of serum phosphate. Despite sleep disturbance being one of the most prevalent and intense symptom burdens identified by hemodialysis patients, relatively few studies have addressed this issue. It is time to formulate sleep therapeutic interventions besides the encouragement of strong social support, hoping which many clinical outcomes including hyperphosphatemia can be better controlled among hemodialysis patients.

Practice of dialysis access interventional nephrology procedures in the Asia-Pacific region: Getting lay of the land

Jasuja S, Gallieni M, Jha V, Vachharajani T, Bhalla AK, Tan J, et al.

Nephrology (Carlton), 2023 Dec;28(12):672-681.
PMID: 37697492 DOI: 10.1111/nep.14236

AIM: This cross-sectional survey aimed to determine the prevalence of Interventional Nephrology (IN) practice amongst nephrologists in the Asia-Pacific Region (APR), specifically related to dialysis access (DA).
METHODS: The Association of VA and intervenTionAl Renal physicians (AVATAR) Foundation from India conducted a multinational online survey amongst nephrologists from the Asia-Pacific to determine the practice of IN in the planning, creation, and management of dialysis access. The treatment modalities, manpower and equipment availability, monthly cost of treatment, specifics of dialysis access interventions, and challenges in the training and practice of IN by nephrologists were included in the survey.
RESULTS: Twenty-one countries from the APR participated in the survey. Nephrologists from 18 (85.7%) countries reported performing at least one of the basic dialysis access-related IN procedures, primarily the placement of non-tunnelled central catheters (n-TCC; 71.5%). Only 10 countries (47.6%) reported having an average of <4% of nephrologists performing any of the advanced IN access procedures, the most common being the placement of a peritoneal dialysis (PD) catheter (20%). Lack of formal training (57.14%), time (42.8%), incentive (38%), institutional support (38%), medico-legal protection (28.6%), and prohibitive cost (23.8%) were the main challenges to practice IN. The primary obstacles to implementing the IN training were a lack of funding and skilled personnel.
CONCLUSION: The practice of dialysis access-related IN in APR is inadequate, mostly due to a lack of training, backup support, and economic constraints, whereas training in access-related IN is constrained by a lack of a skilled workforce and finances.

Fulltext Organ donation campaigns: perspective of dialysis patient's family members

Tumin M, Raja Ariffin RN, Mohd Satar N, Ng KP, Lim SK, Chong CS

Iran J Public Health, 2014 Jul;43(7):926-35.
PMID: 25909060

BACKGROUND:
Solving the dilemma of the organ shortage in Malaysia requires educating Malaysians about organ donation and transplantation. This paper aims at exploring the average Malaysian households ' preferred channels of campaigns and the preferred campaigners in a family setting, targeting at the dialysis family members.

METHODS:
We analyzed the responses of 350 respondents regarding organ donation campaigns. The respondents are 2 family members of 175 dialysis patients from 3 different institutions. The information on respondents' willingness to donate and preferred method and channel of organ donation campaign were collected through questionnaire.

RESULTS:
Malaysian families have a good tendency to welcome campaigns in both the public and private (their homes) spheres. We also found that campaigns facilitated by the electronic media (Television and Radio) and executed by experienced doctors are expected to optimize the outcomes of organ donation, in general. Chi-square tests show that there are no significant differences in welcoming campaigns among ethnics. However, ethnics preferences over the campaign methods and campaigners are significantly different (P <0.05).

CONCLUSION:
Ethnic differences imply that necessary modifications on the campaign channels and campaigners should also be taken under consideration. By identifying the preferred channel and campaigners, this study hopes to shed some light on the ways to overcome the problem of organ shortage in Malaysia.

Fulltext Periodontal Health of Pre-Dialysis Chronic Kidney Disease Patients in a Northeast Peninsular Malaysia Tertiary Hospital

Ibrahim HA, Kassim NK, Jamsari FZ, Zainuddin SLA, Hanafi MH, Adnan AS

Malays J Med Sci, 2020 Feb;27(1):106-114.
PMID: 32158350 MyJurnal DOI: 10.21315/mjms2020.27.1.11

Introduction: Chronic kidney disease (CKD) is associated with periodontal disease due to its hyperinflammatory state. Limited studies have explored the prevalence of periodontal disease among CKD patients in Malaysia.
Objective: To assess the periodontal status of pre-dialysis CKD patients in Hospital Universiti Sains Malaysia.
Methods: A total of 46 pre-dialysis CKD patients who attended the nephrology clinic at Hospital Universiti Sains Malaysia were enrolled in this study. Periodontal examination was performed using the periodontal probing depth (PPD), clinical attachment loss (CAL) and plaque index.
Results: The majority of the CKD patients were Malay (95.7%) and 80.4% were males. The mean age of the patients was 58.5 years. Using PPD measurement, 37 (74.0%) of the patients had mild periodontitis, 9 (20.0%) had moderate periodontitis and 3 (6.0%) had no periodontitis. Based on CAL measurement, 12 (26%) patients had mild periodontitis, 29 (63.0%) had moderate periodontitis and 5 (11%) had severe periodontitis. The mean (standard deviation [SD]) value of mild and moderate-to-severe periodontitis by PPD measurement were 4.26 (0.26) and 5.24 (0.36), respectively. The mean of mild and moderate-to-severe periodontitis by CAL measurement were 2.66 (0.62) and 4.98 (0.73), respectively. There was no correlation between the periodontal parameters and estimated glomerular filtration rate (PPD: r = -0.160, P = 0.914; CAL: r = -0.135, P = 0.372; plaque index: r = 0.005, P = 0.974).
Conclusion: This study revealed a greater prevalence and severity of chronic periodontitis among CKD patients. Thus, the periodontal health of CKD patients' needs to be screened and monitored.

Perception of quality of life amongst end stage renal failure patients undergoing haemodialysis

Ho SE, Ho CC, Norshazwani N, Teoh KH, Ismail MS, Jaafar MZ, et al.

Clin Ter, 2013;164(6):499-505.
PMID: 24424213 DOI: 10.7417/CT.2013.1627

AIMS: The objective of the study was to examine the quality of life amongst the end stage renal disease (ESRD) haemodialysis patients in Malaysia.
MATERIALS AND METHODS: A cross sectional descriptive study was conducted on 72 ESRD patients at a Dialysis Centre in Malaysia. The modified KDQOL-SF™ subscales, kidney disease-targeted scale and 36 item health survey scale questionnaires were used.
RESULTS: The overall health rating was 66.73 ± 11.670 indicating good quality of life. There was no significant difference between quality of life for the different domains according to gender (p >0.05). However, there were significant differences between quality of life in the domain of burden of kidney disease. Physical functioning deteriorated significantly with age (p=0.012) while social functioning was lowest in the 50-65 years age group (p=0.037). Those who had no morbidities had significantly better scores on the effects of kidney (p=0.036), burden of kidney disease (p=0.011) and physical functioning (p=0.025).
CONCLUSIONS: Patients undergoing haemodialysis have been found to have good quality of life despite having ESRD. It is therefore of paramount importance to constantly monitor the standard of care for these patients to enable them to live their life to the fullest.

Fulltext Determinants of compliance behaviours among patients undergoing hemodialysis in Malaysia

Chan YM, Zalilah MS, Hii SZ

PLoS One, 2012;7(8):e41362.
PMID: 22870215 DOI: 10.1371/journal.pone.0041362

BACKGROUND: Patients with end stage renal disease often fail to follow prescribed dietary and fluid regimen, leading to undesirable outcomes. This study aimed to examine and identify factors influencing dietary, fluid, medication and dialysis compliance behaviours in patients undergoing hemodialysis.
METHODS: This was a cross-sectional study which employed purposive sampling design. A total of 188 respondents were recruited from 14 dialysis centres in Malaysia between 2008-2011. Self-reported compliance behaviours and biochemical measurements were used as evaluation tools.
RESULTS: Compliance rates of dietary, fluid, medication and dialysis were 27.7%, 24.5%, 66.5% and 91.0%, respectively. Younger, male, working patients and those with longer duration on hemodialysis were found more likely to be non-compliant. Lacks of adequate knowledge, inadequate self-efficacy skills, forgetfulness and financial constraints were the major perceived barriers towards better compliance to fluid, dietary, medication and dialysis, respectively.
CONCLUSIONS: Healthcare professionals should recognise the factors hindering compliance from the patients' perspective while assisting them with appropriate skills in making necessary changes possible.

Rothia dentocariosa repeat and relapsing peritoneal dialysis-related peritonitis: a case report and literature review

Keng TC, Ng KP, Tan LP, Chong YB, Wong CM, Lim SK

Ren Fail, 2012;34(6):804-6.
PMID: 22506572 DOI: 10.3109/0886022X.2012.678208

Peritonitis is well recognized as the Achilles tendon of peritoneal dialysis (PD). Reoccurrence of peritonitis due to the same organism, defined as either repeat or relapsing peritonitis under the 2005 guidelines by the International Society for Peritoneal Dialysis, often results in PD technique failure. Rothia dentocariosa, a low-virulent human oropharynx commensal, is a rarely reported pathogen in human infection, particularly infective endocarditis. R. dentocariosa PD-related peritonitis is exceedingly uncommon yet potentially results in repeat or relapsing peritonitis which requires catheter removal. We report a case of R. dentocariosa repeat and relapsing peritonitis in a PD patient who was treated successfully with antimicrobial therapy.

Fulltext Mixed-genotypes infections with hepatitis C virus in hemodialysis subjects

Hairul Aini H, Mustafa MIA, Seman MR, Nasuruddin BA

Med J Malaysia, 2012 Apr;67(2):199-203.
PMID: 22822643 MyJurnal

Mixed-genotypes hepatitis C virus (HCV) infections are normally ignored in chronic hemodialysis patients. The aim of this study is to investigate the prevalence of mixed-genotypes infections among hemodialysis patients in Pahang province, Malaysia. Reverse-transcription and polymerase chain reaction methods were performed using two different sets of primers, targeting the 5' untranslated region and nonstructural 5B region. Target region base sequences were obtained by direct sequencing. Discrepancy in outcomes from phylogenetic analysis of both regions suggests double infections. Of 40 subjects in eight hemodialysis centres, evidence of mixed-genotypes infections was found in 5 subjects (12.5%) from three different centres. Four patients were infected with mixed genotypes 3 and 1 and one with genotypes 3 and 4. Cases of mixed HCV genotypes infection were considered high among hemodialysis patients in Pahang. However, further investigation is needed to confirm whether they are true mixed infections or perhaps infection with recombinant virus and also to assess the clinicopathologic characteristics of the infection.

PMID: 22353629 DOI: 10.1111/j.1525-139X.2012.01051.x

The demands for timely catheter insertion have spurred the growth of peritoneoscopic catheter insertion program by nephrologists in Malaysia. We performed a multicenter analysis to study its impact on the growth of peritoneal dialysis (PD) population. Data were collected retrospectively from five centers at the point of program initiation until December 2009. In Center 1, with this program, PD population continued to grow from 25 patients in 2006 to 120 in 2009. In center 2, the program began in 2005, but comprised only 28.6% of total insertions. From 2007 onwards, nephrologists had overtaken the surgeon, inserting from 85% to 97% of the total insertions. In center 3, with the program at its infancy, a modest growth in its PD population was shown. In center 4, nephrologists maintained an annual average of 41.8% of total catheter insertions, and thus maintaining a stable PD population. In center 5, surgeon-assisted PD catheter insertions helped to maintain the growth of its PD, seeing lesser impact from this program. Subanalysis showed that 1-year catheter survival in Center 1 was 85.4%. This study on PD catheter insertion program by nephrologists showed the greatest impact on new center and center experiencing suboptimal catheter insertions by traditional providers.
