In 2014, the Spanish Sociedad Española de Oncología Médica (SEOM) algorithm for the treatment of hyponatraemia secondary to to syndrome of inappropriate antidiuretic hormone (SIADH) in oncology patients was developed. Since it is hypothesised that the adherence to the SEOM algorithm is not 100%, the current retrospective non-interventional study will investigate the perceived and actual adherence of participating centres to the SEOM algorithm and its impact on patient outcomes

An Observational Study to Describe the Adherence to the SEOM Algorithm for the Treatment of Hyponatraemia in Spain

An Observational, Retrospective Study to Describe the Extent of Adherence to the Spanish Society of Medical Oncology Algorithm for the Treatment of Hyponatraemia Secondary to SIADH in Oncology Patients in Spain (ALGA)

Adherence to the algorithm will be evaluated using a pre-defined decision tree that will be provided in the electronic case report form (eCRF) and will be completed by the investigator

Improvement is defined as a change in the baseline sodium level category (mild, moderate or severe) from a worse category to a better category or eunatraemia. Note that the time to improvement of sodium levels was defined as the first date/time of improvement of sodium levels - date/time of collection of serum sodium levels at baseline (for patients where there was an improvement in sodium levels) or as the final date/time of collection of serum sodium levels - date/time of collection of serum sodium levels at baseline (for patients that did not achieve an improvement in sodium levels \[censored patients\]).

Any untoward medicinal occurrence in a patient administered a medicinal product and which does not necessarily have a causal relationship with this treatment (Directive 2001/83/EC amended by Directive 2010/ 84/ EU). An AE can therefore be any unfavourable and unintended sign (e.g., abnormal laboratory finding), symptom or disease temporally associated with the use of a medicinal product, whether or not it is considered causally related to the medicinal product.

Adult oncology patients who have been treated for ≥ 1 episode of hyponatraemia secondary to the SIADH (defined as a serum sodium level \<135 mmol/L)

Recruitment problems leading to smaller sample size than expected (70 patients vs 100). A priori, the impact on precision was considered acceptable (95% confidence interval equal to ± 10.0% with 100 patients vs ± 11.7% with 70 patients).

Number of Patients Managed According to the SEOM Algorithm (as a Result Adherence to the Algorithm Will be the % of These Patients Among the Total Number of Patients)

Adult oncology patients who have been treated for ≥ 1 episode of hyponatraemia secondary to the SIADH according to the SEOM algorithm.

Participants Treated According to SEOM Algorithm

Adult oncology patients who have been treated for ≥ 1 episode of hyponatraemia secondary to the SIADH not according to the SEOM algorithm.

Participant NOT Treated According to SEOM Algorithm

The overall number of patients analysed represents the number of participants for which the data (time in days) was available. As a retrospective chart review, there were some missing data in this outcome measure (date of improvement in this case)

Time to Sodium Level Improvement for Patients Who Were and Were Not Treated in Adherence With the SEOM Algorithm (Days)

Adult oncology patients who have been treated for ≥ 1 episode of hyponatraemia secondary to the SIADH according to the SEOM algorithm and who were candidate for or actually in chemotherapy treatement when the hyponatremia episode occurred.

Subjects With Chemotherapy Treated as Per SEOM Algorithm

Adult oncology patients who have been treated for ≥ 1 episode of hyponatraemia secondary to the SIADH NOT according to the SEOM algorithm and who were candidate for or actually in chemotherapy treatement when the hyponatremia episode occurred

Subjects With Chemotherapy NOT Treated as Per SEOM Algorithm

In this analysis, only the 22 patients who were candidate for chemotherapy during the study period were included, this explains the difference with the total number of participants.

Time to Initiation or Re-initiation of Chemotherapy (Since the Start of the Hyponatraemia Episode) in Patients Candidate for Chemotherapy Who Were and Were Not Treated in Adherence With the SEOM Algorithm.

Length of Hospitalisation (Measured From the Start of the Hyponatraemia Episode to Discharge) for Patients Who Were and Were Not Treated in Adherence With the Algorithm

The overall number of patients analysed represents the number of participants for which the data (time in hours) was available. As a retrospective chart review, there were some missing data in this outcome measure (time of improvement in this case)
