Kidney transplant. Pan-American and Iberian productivity analysis in 2019 with a Mexican and chronic kidney disease perspective.

BACKGROUND: Kidney transplant (KT) is the most common solid organ transplantation in the world. OBJECTIVE: To analyze the information from Mexico on KT, waiting lists (WL) and patients on dialysis between 2012 and 2019 and compare that of 2019 with those of the countries of the American Continent, Spain and Portugal. MATERIAL AND METHODS: The required information was obtained from the Global Observatory on Organ Donation and Transplantation (GODT). RESULTS: Between 2012 and 2019, the annual number of kidney transplants (KTs) in Mexico increased by 12.5%, while the WL by December 31 of each year did it by 86.1%. In 2019, Spain and the US reported the highest KT rates, while Mexico ranked 8th in the Pan-American and Iberian comparison, 6th in the American Continent and 4th in Latin America. Mexico did not report to GODT the number of patients on dialysis in 2019 and 2018. CONCLUSIONS: KTs should be considered an integral part of renal replacement therapies. The GODT reports include the numbers of patients on dialysis for each country. Mexico does not always report this data, probably due to the lack of a national registry of chronic kidney disease, the creation of which should be supported.

ANTECEDENTES: El trasplante renal (TR) es el trasplante de órgano sólido más frecuente en el mundo. OBJETIVO: Analizar la información de México sobre TR, listas de espera (LE) y pacientes en diálisis entre 2012-2019 y comparar la del año 2019 con la de los países del continente americano, España y Portugal. MATERIAL Y MÉTODOS: La información requerida se obtuvo del Global Observatory on Organ Donation and Transplantation (GODT). RESULTADOS: Entre 2012-2019 en México el número anual de trasplantes renales (TR) se incrementó en un 12.5%, mientras que la LE al 31 de diciembre de cada año lo hizo en un 86.1%. En 2019, España y EE.UU. reportaron las tasas más altas de TR, mientras que México ocupó el 8.° lugar en la comparativa panamericana e ibérica, 6.° en el Continente Americano y 4.° en América Latina. México no reportó al GODT el número de pacientes en diálisis en 2019 y 2018. CONCLUSIONES: Los TR deben considerarse parte integral de las terapias de reemplazo renal. Los reportes del GODT incluyen las cifras de pacientes en diálisis de cada país. México no siempre reporta este dato, probablemente por carecer de un registro nacional de enfermedad renal crónica, cuya creación debe apoyarse.

Intraoperative scrub nurse turnover in orthopaedic surgery procedures: An opportunity for improved operating room efficiency.

BACKGROUND: Scrub nurses play a crucial role in facilitating orthopaedic surgeries, and thus intraoperative scrub nurse turnover may disrupt the workflow of the surgical team and prolong duration of surgery (DOS). The purpose of this study was to quantify the impact of intraoperative scrub nurse turnover on operative time of orthopaedic surgeries lasting less than 3h in duration. METHODS: Prospectively collected databases from two institutions were retrospectively queried to identify all orthopaedic procedures of maximum mean duration of 180min from March 4th, 2018 to August 31st, 2022. Cases were divided into two groups, those with scrub nurse turnover and those without. Propensity score matching was conducted to match groups by surgeon, hospital, patient age, gender, and ASA classification. Unpaired t-tests were used to compare mean DOS for each surgical procedure. Average treatment effect on treated (ATET) with 95% confidence intervals (CIs) were calculated. RESULTS: Scrub nurse turnover significantly prolonged DOS for both bone forearm facture open reduction and internal fixation (ORIF) (ATET=21.08, p=0.001), ankle ORIF (ATET=21.26, p<0.001), clavicle ORIF (ATET=16.16, p=0.028), femur intramedullary nail (ATET=11.52, p=0.003), rotator cuff repair (ATET=16.88, p<0.001), partial discectomy (ATET=10.52, p=0.001), total knee arthroplasty (TKA) (ATET=5.69, p<0.001), anterior total hip arthroplasty (THA) (ATET=8.80, p<0.001), lateral THA (ATET=7.02, p<0.001), and uncemented hip hemiarthroplasty (ATET=16.79, p=0.049). CONCLUSION: Intraoperative scrub nurse turnover significantly prolongs surgical times in orthopaedic surgeries lasting up to 3h in duration. This highlights the importance of developing strategies to prevent intraoperative scrub nurse turnover to improve OR efficiency and decrease healthcare costs.

Effectiveness and efficiency of a special program to reduce the bariatric surgery waiting list at a tertiary hospital. / Eficacia y eficiencia de un programa especial para la disminución de la lista de espera de cirugía bariátrica en un hospital terciario.

INTRODUCTION: Bariatric surgery is one of the most common surgical practices in Spain. However, this procedure currently has longest delay on surgical waiting lists (SWL). We have developed a special surgical program that aims to reduce this waiting list and to assess the economic and clinical repercussions in a high-volume bariatric surgery unit. METHODS: A three-month prospective study was carried out comparing outcomes, results and perioperative resources consumed for 45 patients who underwent bariatric surgery. The patients were divided into 2 groups: patients who underwent the standard procedure in the operating room, and patients treated in the special program. Epidemiological, healthcare and economic factors were taken into account. RESULTS: Two homogeneous groups of patients were operated on, successfully reducing the SWL. Morbidity was similar in both groups and the average cost of the surgeries performed was €5,331.40; in the standard group, the cost was €5,372.50±€798.10, and the cost of the special program group was €5,290.30±€685.10, with no significant differences. CONCLUSIONS: In hospitals with a high volume of bariatric surgery, it is feasible to incorporate special surgical programs that are able to reduce surgical waiting lists, while maintaining quality criteria and without incurring a greater expense to the healthcare system.

Renunciations in forefoot surgery. Critical analysis of surgical waiting lists. / Renuncias en cirugía del antepié. Análisis crítico de las listas de espera.

INTRODUCTION: The high prevalence of forefoot pathology generates long surgical waiting lists (SWL). We have detected a considerable number of patients who withdraw surgery, which creates an important distortion in our activity and high expenditure of resources. Our objective is to study the factors related to these resignations, as well as, compare them with other pathologies of high prevalence and ambulatory surgical treatment: carpal tunnel syndrome (CTS) and internal meniscopathy (IM). MATERIAL AND METHODS: Retrospective study of the surgical cancellations on 2,399 patients included in the SWL of the Foot and Ankle Unit of our center for forefoot surgery, between January/2014 and March/2018, both included. RESULTS: We have found 389 renunciations, which represent 16.22% of the inclusions in SWL, with 84.83% of women. The pathologies with the highest rate of resignation have been Morton metatarsalgia (24%) and hallux rigidus (20.16%). The most frequent pathology, hallux valgus, records 15.96% of resignations that occur mostly between 6 and 9 months. In the CTS and IM, the resignation rate has been 17.42 and 8.92%, respectively, with higher resignation rates in the first 3 months. CONCLUSIONS: The withdrawal of a scheduled intervention on the forefoot registers a high frequency in our environment, which can be related to factors such as the type of pathology, its natural history, response to orthopedic interventions, time in LEQ, and other non-specific ones on which we must investigate, to rationalize and establish duties in our SWL.

Teledermatology in Remote Parts of Chile: Experience in 4 Isolated Rural Areas. / Teledermatología aplicada en zonas extremas: experiencia de 4 centros asistenciales chilenos en ámbito rural y aislamiento extremo.

BACKGROUND: Teledermatology was introduced in Chile to make up for the lack of dermatologists and improve the primary care system's ability to resolve problems. This strategy was implemented in the province of Palena in 2013, but outcomes were not analyzed and reported until now. MATERIAL AND METHODS: Descriptive, cross-sectional study with analysis of inter-rater agreement on diagnoses. All the teledermatology consultations made on behalf of patients in Ayacara, Chaitén, Futaleufú, and Palena from 2013 through 2017 were analyzed. Data were extracted from the MINSAL platform. The κ statistic was used to assess diagnostic agreement. RESULTS: A total of 326 teledermatology consultations were made. The mean (SD) age of the patients was 35.8 (22.4) years. The majority (59.8%) were female. Palena generated the largest volume of cases (40.8%). The mean time until a teledermatology diagnosis was given was 12.6 (22.8) days. This response time decreased to 6.4 (5.2) days after a staff dermatologist from Hospital Puerto Montt joined the program (P=.0005). Diagnosis concordance between the general practitioner and the dermatologist was moderate (κ=0.5). Physical examination by the dermatologist at the hospital of reference (Puerto Montt) was necessary for 20.6% of the patients, and time until a definitive diagnosis for the patient took longer in such cases (25.7 [41.2] days) than for the cases that didn't need a physical evaluation at the Hospital of Puerto Montt (P<.0001). CONCLUSIONS: Teledermatology provides a necessary diagnostic and therapeutic resource for general practitioners in isolated locations. Diagnostic agreement is moderate between the generalist and the specialist, similar to agreement in international studies but lower than agreement reported in other Chilean studies. The reduction in diagnostic response time after incorporation of a dermatologist on staff at the hospital of Puerto Montt was significant. The significant difference between the time for diagnosis under teledermatology and the delay when physical examination is required at the hospital of Puerto Montt identifies an aspect of care management to improve.

Waiting time for kidney transplantation based on calculated panel reactive antibodies: experience of a southern Brazilian center / Tempo de espera para transplante renal com base em painel de reatividade de anticorpos calculado: experiência de um centro do sul do Brasil

ABSTRACT Introduction: The aim of this study was to analyze the waiting list for kidney transplantation in our hospital according to candidate's panel reactive antibodies (cPRA) and its outcomes. Methods: One thousand six hundred forty patients who were on the waiting list between 2015 and 2019 were included. For the analysis, hazard ratios (HR) for transplant were estimated by Fine and Gray's regression model according to panel reactivity and HR for graft loss and death after transplantation. Results: The mean age was 45.39 ± 18.22 years. Male gender was predominant (61.2%), but the proportion decreased linearly with the increase in cPRA (p < 0.001). The distribution of patients according to panels were: 0% (n = 390), 1% - 49% (n = 517), 50% - 84% (n = 269), and ≥ 85% (n = 226). Transplantation was achieved in 85.5% of the sample within a median time of 8 months (CI 95%: 6.9 - 9.1). The estimated HRs for transplantation during the follow-up were 2.84 (95% CI: 2.51 - 3.34), 2.41(95%CI: 2.07 - 2.80), and 2.45(95%CI: 2.08 - 2.90) in the cPRA range of 0%, 1%-49%, and 50%-84%, respectively, compared to cPRA ≥ 85 (p < 0.001). After transplantation, the HR for graft loss was similar in the different cPRA groups, but the HR for death (0.46 95% CI 0.24-0.89 p = 0.022) was lower in the 0% cPRA group when adjusted for age, gender, and presence of donor specific antibodies (DSA). Conclusion: Patients with cPRA below 85% are more than twice as likely to receive a kidney transplantation with a shorter waiting time. The risk of graft loss after transplantation was similar in the different cPRA groups, and the adjusted risk of death was lower in nonsensitized recipients.

RESUMO Introdução: O objetivo foi analisar a lista de espera para transplante renal em nosso hospital segundo o painel de reatividade de anticorpos (PRAc) do candidato e seus desfechos. Métodos: Incluímos 1.640 pacientes em lista de espera entre 2015 e 2019. Para a análise, estimou-se a razão de risco (HR) para transplante pelo modelo de regressão de Fine e Gray conforme o painel de reatividade e HR para perda do enxerto e óbito após o transplante. Resultados: A idade média foi 45,39 ± 18,22 anos. Sexo masculino foi predominante (61,2%), mas a proporção diminuiu linearmente com o aumento do PRAc (p < 0,001). A distribuição de pacientes conforme os painéis foi: 0% (n = 390), 1% - 49% (n = 517), 50% - 84% (n = 269), e ≥85% (n = 226). O transplante foi realizado em 85,5% da amostra em tempo mediano de 8 meses (IC 95%: 6,9 - 9,1). As HRs estimadas para transplante durante o acompanhamento foram 2,84 (IC 95%: 2,51 - 3,34), 2,41 (IC 95%: 2,07 - 2,80) e 2,45 (IC 95%: 2,08 - 2,90) no intervalo de PRAc de 0%, 1%-49% e 50%-84%, respectivamente, comparadas com PRAc ≥ 85 (p < 0,001). Após o transplante, a HR para perda do enxerto foi semelhante nos diferentes grupos de PRAc, mas HR para óbito (0,46 IC 95% 0,24-0,89 p = 0,022) foi menor no grupo PRAc 0% quando ajustada para idade, sexo e presença de anticorpos doador específico (DSA). Conclusão: Pacientes com PRAc abaixo de 85% têm mais que o dobro de probabilidade de receber transplante renal com tempo de espera menor. Risco de perda do enxerto após o transplante foi semelhante nos diferentes grupos PRAc, e risco ajustado de óbito foi menor em receptores não sensibilizados.

Self-management model in the scheduling of successive appointments in rheumatology. / El modelo de autogestión en la agenda de consultas sucesivas en reumatología.

INTRODUCTION: The rheumatology service of Ciudad Real Hospital, located in an autonomous community of that same name that is nearly in the center of Spain, implemented a self-management model of successive appointments more than 10 years ago. Since then, the physicians of the department schedule follow-up visits for their patients depending on the disease, its course and ancillary tests. The purpose of this study is to evaluate and compare the self-management model for successive appointments in the rheumatology service of Ciudad Real Hospital versus the model of external appointment management implemented in 8 of the hospital's 15 medical services. MATERIAL AND METHODS: A comparative and multivariate analysis was performed to identify variables with statistically significant differences, in terms of activity and/or performance indicators and quality perceived by users. The comparison involved the self-management model for successive appointments employed in the rheumatology service of Ciudad Real Hospital and the model for external appointment management used in 8 hospital medical services between January 1 and May 31, 2016. RESULTS: In a database with more than 100,000 records of appointments involving the set of services included in the study, the mean waiting time and the numbers of non-appearances and rescheduling of follow-up visits in the rheumatology department were significantly lower than in the other services. The number of individuals treated in outpatient rheumatology services was 7,768, and a total of 280 patients were surveyed (response rate 63.21%). They showed great overall satisfaction, and the incidence rate of claims was low. CONCLUSION: Our results show that the self-management model of scheduling appointments has better results in terms of activity indicators and in quality perceived by users, despite the intense activity. Thus, this study could be fundamental for decision making in the management of health care organizations.
