Hospital Admissions Secondary to Diseases of the Blood, Blood-Forming Organs, and Immune System in England and Wales

Abstract

BackgroundNon-malignant hematologic and immune disorders-related hospitalization trends are unstudied despite their importance from a public health standpoint. Therefore, this study aimed to define the hospitalization trends of the International Statistical Classification of Diseases-10 (ICD-10) category diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism (B&ID). MethodsWe conducted an ecologic study to analyze hospital admission data obtained from England's Hospital Episode Statistics database and Wales' Patient Episode Database. Hospital admissions data for nonmalignant hematologic disorders and immune disorders were extracted for the period from April 1999 to March 2019. We used the Poisson model to assess trends in hospital admissions. ResultsThe total annual B&ID-related hospital admission (RHA) rate for all categories increased by 137.9% between 1999 and 2019 (p<0.01). Females accounted for 54% of all B&ID-RHA. Around 37% of B&ID-RHA were seen in the age group of 15-59 years and 29% in the age group of 75 years and above. The most common causes of B&ID-RHA were aplastic and other anemias and other bone marrow failure syndromes, ICD-10 category (33%) and nutritional anemias category (28%). Certain disorders involving the immune mechanism category accounted for the least number of B&ID-RHA (8.4%). The highest increase in B&ID-RHA was seen in the nutritional anemias category (3.86 fold), followed by certain disorders involving the immune mechanism (1.28 fold). Iron deficiency anemia accounted for 95.1% of all hospitalizations secondary to nutritional anemias. Around half of all, hemolytic anemia category hospitalizations were secondary to the sickle cell anemia subcategory. ConclusionsHospital admissions trends in non-malignant hematologic and immune disorders changed dynamically among age groups and gender in England and Wales over the last two decades. Understanding these changes has important implications for public health planning.

Postprocedural Complications Hospitalization Pattern Among Paediatric Patients at National Health Service Trusts: An Ecological Study in England and Wales

“…16 These two medical databases were used previously to examine hospitalisation pattern of different clinical outcomes and diseases. [17][18][19][20][21][22][23] Postprocedural complications related hospital admissions were identified using the 10 th version of the International Statistical Classification of Diseases (ICD) system (D78, E89, H59, H95, J95, L76, M96, and N99. 24 The HES and PEDW databases record all hospital admissions, outpatient encounters and Accident and Emergency activities performed at all NHS trusts and any independent sector funded by NHS trusts.…”

Postprocedural Disorders of Eye and Adnexa Admissions Profile

“…21,22 These medical databases were previously used to examine hospitalisation profiles for different health conditions. [23][24][25][26][27] The HES and PEDW databases contain hospital admission data for patients with postprocedural disorders of eye and adnexa from all age groups, which are subdivided into four categories; "below 15 years, 15-59 years, 60-74 years, and 75 years and above." Diagnostic code for postprocedural disorders of eye and adnexa (H59) was used to identify hospital admission.…”

Profile of Hospital Admissions Due to Preterm Labor and Delivery in England

“…Continuous research and publication of new data on preterm labor and births ensures the attention of the world community to prevent and manage such cases efficiently [18]. Previous studies in the United Kingdom have examined the hospitalization profile among different disease areas, however, none of them examined admissions related to preterm labor and delivery [19][20][21]. In this regard, the current study aims to generate an admission profile of preterm labor and delivery in England between 2012 and 2020, and analyze the general trend of such cases with respect to demographic aspects of the mothers.…”
